Subject: [Zope] ZClass based on DTML Document
References: <200002291337.AA27406@rsphy9.anu.edu.au>
Message-ID: <38BC6ED7.94F2BCBC@aHIT.de>

Hi,

I created a POIDocumentClass (ZClass based on DTML Document; meta type
PIO Document) .
Than I created an instance of this POIDocumentClass id 'MyDoc' title 'My
Document'.

Now when I try to find all POIDocumentClass instances in a Folder I do
the following:

<dtml-with aq_parent>
<!--#in "objectItems(['POI Document','DTML Document'])"-->
  <!--#if
"AUTHENTICATED_USER.has_permission('View',_.getitem('id',1))"-->
      <a href="<!--#var "absolute_url()"-->"><!--#var title--></a><BR>
   <!--#/if-->
<!--#/in-->
</dtml-with> 

I get back the right title 'My Document' but absolute_url() returns
http://myserver:8080/foo/%3cstring%3e instead of
http://myserver:8080/foo/MyDoc

When I create a DTML Document instance within the same Folder
absolute_url() works fine.
I suspect there is something wrong with my POIDocumentClass :-(
Can anybody please explain this behaviour ?

Message-ID: <38BC9FB7.305143CF@aHIT.de>

I created a ZClass based upon DTMLDocument.I wanted to have
a DTMLDocument class with some additional integer properties. 
So I decided NOT to derive my class from ObjectManager.
 
Now when I create an instance of my new class within a Folder 
the instance has no id !

I think this is not a feature ;-)

Okay.  Perhaps someone else on the list can answer this one then: I
have a standard Debian install of Zope.  ZServer works fine.  Apache
works fine.  Zope shows up fine in apache.  Except... I can't log in. 
At all.  With any username.  What do I have to do to get Apache to
recognize Zope's authentication?

Don't forget that you can also download Zope and try it out easily. I'm
running it on Win32 for some development tasks, and it did not take much
effort at all to install it and run it locally. So, if you want to continue
playing you can always do that.

In terms of popularity and being supported for a long time, I do believe
that DC has been quite successful in their consulting business, so they'll
be around. And, Zope itself is open source, so there will always be avenues
available for using it.

IMHO, you'll be quite happy wiht what you can do when you migrate those apps
to Zope. In the meantime, though, you can continue using them by setting up
Apache with rewrite rules that allow you to access those CGIs still. Without
knowing anything about your app, it's difficult to state how you would
"interface" with them. There are avenues for doing so. A pretty
straightforward one might be XML-RPC. (Your perl CGIs could access Zope data
via XML-RPC.)

I think Zope is pretty stable (and I think most regular users of it would
agree). It's not generally more likely to die than your system itself. If
you do "low-level" development on a different machine, your database should
be OK. Plus, all you need to do is back up your Data.fs file. If something
got really messed up, you just drop in the back up file.

I think the answer to "what if Zope goes down" is really the same kind of
thing as "what if the server goes down?" or "what if the drive crashes?"

If you really want, there is a Zope product that will mirror your site in
HTML (and others have used wget to mirror the site in HTML). But, I think
it's better to just maintain a solid Zope, because your site quickly goes
from being a static HTML thing to being a dynamically produced, interactive
thing which can't be reasonably represented by HTML.

People on this list have done benchmarks using ab and other tools. I think
the general consensus was that with a moderate machine and a moderately
dynamic app you can do a million hits+ per day. Through more machine at it,
or go for ZEO (which lets you mirror the object database on multiple
machines) and you can handle lots and lots of traffic.

Our site (Byproducts.com) has been running on Zope since last May. I've had
very little downtime and I don't think I would blame any of it on Zope.

Subject: [Zope] trees and namespaces newbie q
Message-ID: <38BC6375.1CF97892@open.ac.uk>

Still much to learn.

I'm trying to write code to display a tree where different
kinds of node require different display action.  Each node has a
property (possibly acquired) "kind".  For nodes which reach
the innermost <dtml-else> in the code below I want the dtml
content rendered.  How can I do this?  If i refer in
some way to PARENTS[0] then id goes up with it.

Please, please, please, what expression will work here
to get the content of "id" rendered?

Code follows
------------
<dtml-tree expr="lists" branches=objectValues sort=order>

        <dtml-if "meta_type=='Folder'">
            <dtml-var title_or_id>
        <dtml-else>
            <dtml-if "kind=='discussion'">          
                    <A HREF="<dtml-var listURL>">
                    <dtml-var title_or_id></A>
            <dtml-else>
                     
                         <dtml-var id>

        </dtml-if>
        <dtml-if listinfo>

Just to follow up to myself so you know: I have seen snippets about
RewriteRules all over the place for using Apache with Zope...

I have tried everything i've found, and nothing has worked so far. 
(The RewriteRules appear to do nothing at all...)

Lot's not there. The only ones that show are those that use Zope built-in
ZServer. If your Zope is hidden behind a different web server and that
webserver's ID string hasn't been changed to mention Zope, then your site
doesn't show. Anyway none of my sites show up on the Netcraft list.

This is from the "Other Uses" page, right?  In that example, it is an error
to access the folder, since it is only meant to act as a placeholder for a
session value.  The IndexError occurs when the code tries to access the last
element in the remaining path, but there *is* no remaining path!

Access Rules execute before any authentication takes place, so
AUTHENTICATED_USER doesn't exist yet.  This also prevents them from
accessing any other Zope objects unless you give the Rule a Proxy role.

It looks like you need GenericUserFolder or UserDB.

Subject: [Zope] unhandled connect event
Message-ID: <010401bf831d$2f850440$6e00a8c0@redindustries.com>

(short time reader, first time poster)

So I've set up my zope installation to test it out for use as the intranet
server and content management system for my company. One of the features
that I intend to use heavily is the FTP access, the main users of the system
will be designers and their clients, so I want to set up an interface that
works with existing tools <DTML-rah-rah yeah>.

However everytime I connect with ftp (used Dreamweaver's FTP client as well
as EMACS) I get an "PROBLEM(100) ZServer unhandled connect event" error from
Zope. I've just upgraded to 2.1.4 which solved the crashing problem for the
most part.

My question is what is an "unhandled connect event", can I make a connect
event be handled? Is there a howto, a document or a previous thread on this
subject?

Help, I want to be a fanatic!

Right.

Yes.  One thread will win, and one thread will loose.  The winner will
get the new id.  The looser will try again.  The looser will find out
when it tries again the the id it wants is taken, and will report that
to the user.  The user picks another id.

No, but a programatic resolution protocol is planned for future releases
of ZODB.

The chances of colision are very small unless you have an incredibly
write intensive application (which is not ideal for ZODB filestorage. 
In that case, you should store your information in a RDBMS).  This the
"optimism" in optimistic.

WU IMAP on a RH 6.x box is *bizarre*.,

Ok, I kicked this off before dinner, having added some debugging output to
imaplib.py.  When I came back, there was a TON of it dumped across the console
at which I was running Zope, but no mail.  Basically, it had walked down through
all the .gnome/* directories, sucking up bitmaps, retular files, subdirectories,
everything (ICK!).

Maybe we need to add a property to the WorldPilot object which lets you
configure the folder passed to the initial list() call (e.g., to be something
like "~/Mail").  This parameter would default to the empty string, so that the
Cyrus clients would continue to operate as before.  I'll see if I can't come up
with some kind of patch.

If you click on the "what's that site running" link, and enter yours, it
will automatically appear in the next report set.

My sarcasm meter is in the shop after an accidental exposure to
comp.lang.perl.misc (ugly story, don't ask), so I'm not sure how big a brick of
salt to apply.  WU IMAP is a nice stick for clobbering those who think Zope's
documentation stinks;  there is absolutely *nothing* in the package to give the
hapluse admin any clue how to configure the damn thing.

I spent about 4 hours this weekend prowling the net looking to resolve this
issue.

Hi Tres,
This was written up last week and after a little digging on egroups (I thought I
had saved that message) I finally found it. Jo Meder provided the following
information

<quote>
Chances are, that the request to "LIST *" in directory "" that 
imaplib issues cause your imapd to begin scanning your whole home 
directory which can be a lot of data, as we all know.

I worked around this problem by creating /etc/c-client.cf with the
following contents (the first line is required by imapd, otherwise
the file is not accepted):

--------------------------------------cut here -------------------
I accept the risk for IMAP toolkit 4.1.
set black-box-directory /var/spool/imap_folderlinks/
--------------------------------------cut here -------------------

I then created /var/spool/imap_folderlinks and symlinked the
directory in which my mailbox folders reside to 
/var/spool/imap_folderlinks/jo

Repeat for all users on the system and set permissions appropriately.



        Jo.

Also some information on this can be found in the file imaprc.txt that should
be in /usr/doc/ or where ever RH dumps it. (I'm running this on SuSE myself.) I
have tried this fix but I probably will.

Subject: [Zope] RE: Different Login Screens for Management and User?
Message-ID: <38BCA9A0.C5CEA34@cs.rutgers.edu>

I was working on the same kind of problem (see my earlier post today),
and I think
I found some solution, thanks to the many hints here and in the zope-ptk
list. It's
actually quite simple.

The trick is to play with exceptions. In your standard_html_header,
include something
like (replace 'Member' with the role you want):
<dtml-unless "AUTHENTICATED_USER.has_role('Member')">
   <dtml-raise type="Please Login!">
                <p>Please login before entering!<p>
   </dtml-raise>
</dtml-unless>

When the error is raised, the standard_error_message is called, so from
there,
you can do some more tests and go to the appropriate login page. I have
not
fully tested this yet, but I think it should work. I think if you put
type=Unauthorized in the dtml-raise tag, you should get the usual HTML
login instead of the error.

Anyone has a better (more elegant/original/creative) solution?

I get this exact same problem trying to add completely normal File Objects
to my Zope site.
I can create the object empty if I don't include an upload, but the instant 
I try and upload anything it dies with the above error.
It happens _constantly_ for me, not just time to time.

Thank you. This 'patch' did in fact work although the problem was in fact more
subtle than originally described - the 'unhandled' type error only
arose if I used joins in the select part of the statement.

Message-ID: <20000301011319.A10204@devware.com>

So, if I am grokking the whole zope thang properly here, then
theoretically, when I imbed objects within my zope documents, I
shouldn't hardcode in specific urls to them.  Instead, I should treat
them almost as if they are always in the current directory, even if
they are a couple of folders up.  This way, if I want to override some
behavior in the future, I just copy the object down into the current
folder and edit it.  I notice however, that if I do this, it plays
hell with browser caching because the browser winds up pulling things
from different places all the time even if it's actually winding up
pulling the same document down.  How do other people deal with this?

Hi Lucas,

I am the original author of zGold, and I'd like to explain where it came
from and what happened to it subsequently.

zGold was originally written as an exercise of learning and also as an
example site for a conference/exhibition here in the UK.

At creation time there was no intention of releasing it to the public at
large.  It was however made available purely as a 'teaching aid'.

Subsequently it was proved that there was a serious security hole in it that
allowed users to see the clear-text passwords/usernames of other users.

Also since this was created in my 'spare time', I have had no further time
to allocate to it and it has sort of died of neglect.

That being said, I still have the original tarball hanging around and anyone
who wants it can mail me and I'll get it sent out.

caveat:
zGold is not supported in anyway and is not 'production' ready.  Use it at
your own risk.  I will not be liable/responsible for any/all problems it may
cause.

Thanks for listening.

Hello,

I want to import a static HTML web site (about 10 directories,
100 HTML pages, 10 PDF Files, Images ...) into Zope 2.1.4

But I couln't find any documentation about it.

Ok, I found load_site.py
 ./load_site.py [options] url file .....    

 But:
 	Which 'url' should I pass here?
 	Does 'file' mean that I only can import one file an not a 
		whole directory tree?
 
Where can I find more information?

Thank you
Veikko

Howdy all.  Please note that "More" under "Zope News" has the old style
display.

Question: do you think we should have a knob available for members that
lets them toggle the home page between old style and new style?

Subject: [Zope] ODBC + Zope + UNIX
Message-ID: <200003011127.VAA65638@mail.theinternet.com.au>

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

Hmm .. this sounds really weird. 

In my case I observed the following.

Structure:

/
  +Intermobil
    +daten (up-/download section with form for upload, dtml-methods,
external methods etc)
       +category1
       +category2
       +... (sub- and subsubfolders for storing the files)

testfile is a Winzip/Zip file (1.129 KB), uploading it gives the error.

I created a test folder somewhere else and pasted the content of the
daten folder (without category subfolders), tried to upload my zip file
there .. and -voila- it worked.

Then I changed the upload method in my test folder by inserting a
<dtml-with "Intermobil.daten"> in order to redirect the upload into a
category subfolder of the original daten folder .. and -surprisingly for
me- the upload of the test file worked, too.

I deleted the file, went back to daten, tried again and got the same
error as before.

So here I'm really confused, cause I don't know where to look and what
exactly could have caused this problem.

Thanks for bringing up this to the list again,
Thomas

Howdy all.  Please note that "More" under "Zope News" has the old style

Question: do you think we should have a knob available for members that

Message-ID: <38BD079B.3F5D35D5@imeme.net>

Zopistas,

I'm setting up zope on a linux box with support for large files.
(>2gb).  I need to make sure that the ZODB will continue to work
properly past this point.  Is the filesystem stuff the ZODB does handled
by python or ZODB?

If the answer is ZODB, where can I look for fs calls to make sure
they're 64 bit?

Thanks,

   It is an URL to a Zope folder. If, for example, you've installed Zope on
http://my.server/path/to/Zope/, and you want to upload your site into
http://my.server/path/to/Zope/virtual/site (the folder /virtual/site should
be created before using load_site.py), the URL will be just
http://my.server/path/to/Zope/virtual/site

   The file can be a file, or a directory, or a list of files and
directories...

Use the absolute_url() method on the objects. 

That way, your generated HTML will contain absolute URLs to the objects,
that are the same across different Folders in your site even when the
object is acquired from elsewhere. Overriding as you described will
still work the same, the URLs will reflect the change accordingly.

Syntax variations (as always from the top of my head, not tested, YMMV):

  <dtml-var "object.absolute_url()">
  <dtml-var object url>
  &dtml.url-object;

The last notation is especially useful in HTML tag attributes, as it
won't break WYSIWYG HTML editors:

  <a href="&dtml.url-object;">Go to object</a>

Brian,

I think it's a permissions thing with tinytable. There's a permission called
something like 'access tinytable contents' which you need to give to the
anonymous user in the squishdot folder.

Well, that's how I cracked it, anyway...

cheers,

Hello there,

we got a site up and running (its actually a shop solution based on
zope).
Platform is NT, zope version is 2.1.4.

Most of the time, the site is running very fast. But some times it
hangs.
It does not use much processor-time at this moment (arount 14%) but
it does not process any requests for some seconds.
Its very annoying. Does anyone know how to avoid such behavior?

It seems to me, that index_html is the default DTML document within a
Zope directory.
Can or should I change it to index.html? And where?


Thanks

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

What optimization do you have NT set for?

File Serving, Network processes, or local use?

By default NT optimization is set for file serving. This means that if some one is making heavy use of the file serving cpabilities
of the machine it gives less time to network processes like zope.

Hello there,

we got a site up and running (its actually a shop solution based on
zope).
Platform is NT, zope version is 2.1.4.

Most of the time, the site is running very fast. But some times it
hangs.
It does not use much processor-time at this moment (arount 14%) but
it does not process any requests for some seconds.
Its very annoying. Does anyone know how to avoid such behavior?

   Looks like a bug in HTML parsing. There is no simple solution for this.
When I got some free time (and it shouldn't be in the nearest future) I'll
add additional processing into the parser in load_site.py.

   You don't need to. Just create DTML Methtod index_html and put
<dtml-var index.html> in it. That's all.

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.

The how-to list is a bit daunting; also I get the feeling that
there's a level of jargon necessary just to figure out what 
documentation to read.  I don't have that, so I haven't found
what I'm looking for.

Is there anything like what I'm looking for?

But, on the other hand, there is not much file-serving at all from this
machine.
I only use it to transfer log-file or such.
All other communication is over Zope only.

It appears to me it could be some dead-lock situation inside Zope or
medusa.

Subject: [Zope] Best way to run Zope for hosting apps by multiple developers?
Message-ID: <000901bf8398$f3019ca0$24886883@uoguelph.ca>

Hi,

The University of Guelph is looking at making Zope hosting available
to our departments and organisations. Because we want to be able to
use MS Access databases, we propose to run Zope on NT (so that we can
use Z ODBC). In essence, we're looking at using Zope within an ISP
hosting model, where we will provide the infrastructure and our
clients will do their own development.

I'm trying understand how to design a Zope system to achieve two
things: 1, make it less likely that a poorly written app will
compromise the service for other developers, and 2, establish a test
environment where applications can be debugged, and then moved to a
production server.

I have two questions:

1.
I've read the FAQ for ISP's, and I've seen references in the
documentation to ways of configuring a system so that Zope so that
each client gets their own instance of Zope. This would presumably
help to insulate one Zope app from another. However, I can't find any
details about how that's done... can anyone point me to more info?

2.
Given developers with administrative control of their own folders on
two Zope servers (test and production), how can I make it possible for
them to take a test application (consisting of a set of Zope objects,
let's say within one Zope folder object), and move it to a production
Zope server. I can do this by exporting from one Zope server and
importing into another, but this involves giving the developers access
to the file system (they must place their exported object in the
"import" directory on the target Zope server), and all developers will
be dropping their objects in the same place. It's not elegant, and I
can foresee various management problems and security risks arising
from it. Are there other ways to migrate a Zope application from one
Zope server to another?

Thanks in advance for any pointers,

Nick Dobbing.

Hi:

I've been using DTML successfully to generate around 20+ reports outside
of zope itself.  The result come back from the DB as a pdf document.  The
solution has worked well.

It looks like there might possibly be a bug in the dtml totalling process,
however, when dealing with larger numbers.  The results on one report are
accurate for a 20 row table with smaller totals (say, e.g., 51518), but
the larger totals are incorrect (e.g., it reports a number say in the
300,000 range rather than 1,378,835).  The DTML for that column (the TOTAL
column) is: 

<!--#var total-TOTAL fmt="%15d"-->

Has anyone else seen this? The version of DTML I'm using is from the last
quarter or so of last year.  Any ideas?

All - Have a problem which I am certain many of you have already
encountered.

With most web servers, you can create specific web server instances that
listen to virtual network interfaces on the server (virtual IP addresses).
For example, I can have multiple httpd instances, with httpd1 listening to
192.168.1.101 and httpd2 listening to 192.168.1.102 on a box where the
physical IP address is 192.168.1.100.  This is configurable within the web
server.

I want to be able to have Zope listen to a specific network interface, i.e.
- a virtual IP address that has been created on the server.  This will allow
me to have multiple Zope sites running on the same machine.  How can this be
accomplished?  Any/all suggestions are greatly appreciated.

Thanks,
-Brian

You could run Zopes behind an Apache server and connect via ProxyPass or 
FastCGI. This would even allow virtual servers on one IP address.

I will be roasted -- I thought I'd followed these directions already, and still
had it hang.  When I went back to try again, I discovered that the symlinks were
screwy (how imapd found my home directory at all is a good question).  When I
clean them up, it works!

Hmmm, /usr/doc/imap-4.5 has only a README file, which doesn't mention the
/etc/c-client.cfg file at all (it talks about building the package, and setting
up the /etc/services and /etc/inetd.conf files to make IMAP work).  Thanks very
much for reposting those directions!

IMHO this is not necessary:

just use versions for your developpment work, then commit your version

If you want to stick with Basic HTTP Authentication, the key is to persuade
Apache to pass that info through.  On my setup, this involves adding the

Message-ID: <Pine.GSO.4.10.10003011156580.1074-100000@isis.visi.com>

Hi everyone,

I've grepped through the source and consulted the ZQR, but I still haven't
figured out how to use bobobase_modification_time. I've got a directory
with a file object, and I'd like index_html to display when that file
object was last modified. I've tried all manner of syntax combinations,
but I can't get it to refer to the modification time of a given object and
not just the modification time of index_html. Suggestions?

-Tim

Subject: [Zope] Dealing with Dictionaries
Message-ID: <4.2.2.20000301125741.00b6b100@saladin.aisys.com>

I have a DTML method from which I want to answer a dictionary.  It looks 
something like this:

<dtml-return "{'foo':'bar', 'biff':'boom'}">

I want to be able to use this information in two different ways.  First, I 
want to be able to get a list of keys from the dictionary.  Second, I want 
to be able to get a list of values.  I could easily do this in Python, but 
I'm sure there must be a simple way to do this in DTML.  I tried something 
like:

<dtml-return "_['dictionaryVariableName'].keys()">

but that didn't work.  I did notice that if I just used 
"_['dictionaryVariableName']" I actually got the keys.

Basically I'm trying to create a system by which a user can enter a full 
string and an abbreviation for the string.  I want to be able to produce a 
list of the full strings, and I want to be able to produce a list of the 
abbreviations.

Any help would be appreciated.

Thanks.

The ZODB uses a "pluggable" Storage-derived object to do the actual reads/writes
(this is where Ty Sarna's BSDDB Storage gets plugged in).  The "standard"
Storage is the FileStorage, defined in
$ZOPE_HOME/lib/python/ZODB/FileStorage.py.

   Frank, I agree, however I probably should have been more specific.  I
would like to be able to do this using ZServer rather than using Apache or
in my case Netscape Enterprise Server.  Do you know if ZServer supports
this?

Use the source. :)

From z2.py:

  -a ipaddress
    The IP address to listen on.  If this is an empty string
    (e.g. -a ''), then all addresses on the machine are used. The
    default is %(IP_ADDRESS)s.

so in your start script, add: -a xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is the IP address you want to hook to.

Cheers

Bill

1: What is your timezone setting. It could be that dates are displayed in a
different timezone.

2: If you do your test from a DTML Method, you'll be shown the modification
date of the container it is called on. For an explanation, see:

I think I found the problem, at least for my purposes. :)  I'm not sure
if this has already been corrected in the latest versions of DTML or not
but it might be worth a check.

DT_InSV.py line 239 was:
  s=item*item

Instead, I'm now using:
  if type(item)==type(1): s=item*long(item)
  else: s=item*item

Looks like this information is needed to calculate some of the other
statistics and when the item is a large integer it will cause an
exception.  The exception is then caught and results in that item
be omitted from some calculations, such as the total.

Hi Eric:

I'm not sure how much of what I've done would apply to your situation.
Basically, the powers that be wanted some complex reports for an Access
application hooked up to SQL Server.  Access reports were not anywhere
near flexible enough to produce the output they wanted.  Consequently,
I ended up building a reporting interface onto the rather low-level python
pdf module and then hooked it up to the DB.  That way I was able to
do most of the complex stuff in python, use DTML templates whenever
possible, and output the results in pdf.  When the user clicks on a report
in access, the application shells out without them knowing it and the
next thing they know a pdf pops out in Acrobat.

I gave some thought making it available to whoever might find it useful
but haven't had much time to make it more friendly.  In particular, I
might take the pdf wrapper, which allows for high level pdf
formatting (for switching font sizes, styles, page numbering, headings,
etc), and somehow hook it up to zope.  Sometime after I started,  someone
did come up with a pdf document hook for zope, but it didn't offer the
formatting options I needed and my reports weren't going through zope.  It
might be worth a look, however, for your purposes.

If you can get away with it, avoid PDF documents altogether and just use
DTML to web enable your reports through zope.  I ended up using pdf
because the users didn't want to web enable this stuff, wanted more
precision then browser formatting allowed, and I thought it would be kind
of neat to try....

Subject: [Zope] Advanced DTML Question
Message-ID: <4.2.2.20000301155145.00b6c400@saladin.aisys.com>

I'm trying to write a DTMLMethod which will write out a list of data items 
found from a catalog, sorted in alphabetical order.  This is 
easy.  Basically I do something like this:

<dtml-in "Catalog(meta_type='foo')" sort=someAttribute>
     <dtml-with "Catalog.getobject(data_record_id_)">
         <dtml-var objvar1><dtml-var objvar2> ...
     </dtml-with>
</dtml-in>

I've got this working, no problem.  Now, since the list of these items 
might be somewhat long, I want to build a simple index at the top of the 
page and use page anchors to get to key points on the page. Basically I'm 
going to display the alphabet and when the user clicks on a letter, the 
page should scroll somewhere in the vicinity of an item which starts with 
that letter.  To that end, what I would like to do is have some code inside 
of my dtml-in loop which gets the first letter from the current entry, 
checks to see if an anchor for that letter has been written, if not, a new 
anchor tag is inserted into the stream.  My problem is I don't really know 
how to code this up.  It seems like maybe that at least some of this should 
be done at the Python level but I'm not quite sure how to split up the 
functionality.

Has anybody done anything similar who would be willing to give me some 
advice as to the best way to go about solving this problem?

Thanks.

Quick, possibly misleading idea:  if you can give your Catalog entries a
brain class with a function "anchorGroup" which returns the first letter of
the entry, then you can use <dtml-if sequence-first-anchorGroup><a
name="&dtml-anchorGroup;"></a></dtml-if>

That should have worked.  You should be able to manipulate your dictionary
just as you would expect.  What happened when you tried it? What do you get
from <dtml-var expr="_['dictionaryVariableName']">?

"Brain Class?"  Could you explain that a bit?  It so happens that the 
objects I'm getting out of my catalog are instances of a ZClass that I 
created.  That ZClass inherits from a basically empty Python base 
class.  Is this what you mean by a "brain class"?  If so, are you saying 
that I should just define a method in my Python code which does the 
"anchorGroup" thing?

Even if this isn't what you meant, I think I like the idea that you are 
proposing.  I just need to make sure that I actually understand what you 
are suggesting.

Thanks.

Thanks for the info on your PDF implementation.

Here's my situation:
I currently have a Java applet that collects data from my users.  The applet
runs some calculations and sends the results to me via email.  I copy &
paste the data into a Win32 VC++ app I wrote that converts the data into
"Forms Data Format" (FDF) using Adobe's SDK for generating FDF files.  I am
using Adobe's fdf DLL right now, but I'm excited about the idea of moving
this to Zope - No more Applet for my clients to download!!!

I have ZERO Python experience.

I use PDF / FDF because I am filling PDF files that are created by a
governmental agency; these are 'State Standard' forms, so I want to stick
with them instead of generating dynamic forms using Zope.

Question:  Are you using a Python code supplied by adobe for generating your
FDF file?  If so, I would be VERY interested in any Python code you'd be
willing to share that ties Zope to the Adobe code.

Thanks for your response.

PS, I'm replying to you and CC'ing zope@zope.org.  Is this an acceptable way
to keep the mailing list folks in the loop?
PSS, what's your name?

Eric.

// I'm not sure how much of what I've done would apply to your situation.
// Basically, the powers that be wanted some complex reports for an Access
// application hooked up to SQL Server.  Access reports were not anywhere
// near flexible enough to produce the output they wanted.  Consequently,
// I ended up building a reporting interface onto the rather
// low-level python
// pdf module and then hooked it up to the DB.  That way I was able to
// do most of the complex stuff in python, use DTML templates whenever
// possible, and output the results in pdf.  When the user clicks
// on a report
// in access, the application shells out without them knowing it and the
// next thing they know a pdf pops out in Acrobat.
//
// I gave some thought making it available to whoever might find it useful
// but haven't had much time to make it more friendly.  In particular, I
// might take the pdf wrapper, which allows for high level pdf
// formatting (for switching font sizes, styles, page numbering, headings,
// etc), and somehow hook it up to zope.  Sometime after I started,  someone
// did come up with a pdf document hook for zope, but it didn't offer the
// formatting options I needed and my reports weren't going through
// zope.  It
// might be worth a look, however, for your purposes.
//
// If you can get away with it, avoid PDF documents altogether and just use
// DTML to web enable your reports through zope.  I ended up using pdf
// because the users didn't want to web enable this stuff, wanted more
// precision then browser formatting allowed, and I thought it would be kind
// of neat to try....

No problem. 

BTW: I just discovered this neat function called string.replace(). =)

This is almost certainly faster:

    string.replace(data, '\r\n', '\n') 

I swear, not a day goes by that I don't learn something new about Python.

Subject: [Zope] How to check memory usage in Python
Message-ID: <20000301225439.43329.qmail@hotmail.com>

Hi,

This is more a Python question. How can one
check the RAM memory usage of a Python program
from within itself? Is there such a function?
(Is it platform independent? I mean, does
such a function exist for most platforms?)

If such a function does not exist in Python,
how can one do it from Unix (or Windows) shell
calls?

thanks,

Hung Jung

Subject: [Zope] Zope Weekly News
Message-ID: <Pine.BSF.4.21.0003011851120.5888-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * XML.com has published another Zope article by Amos Latteier,
    titled "Advanced XML Applications in Zope"

    http://www.xml.com/pub/2000/02/23/zope/index.html


New Products

  * Software Product: PMPSurvey, by "sleeper"

    This is another survey product.  It supports single and multiple
    answer questions.  It may easily be embedded within other web
    pages, and reportedly sports a nice management interface.

    http://www.zope.org/Members/sleeper/PMPSurvey


Updates

  * Software Product: FSSession, by "gaaros"

    This product can be used to maintain arbitrary per-visitor data
    (session data) without burdening your ZODB with excessive
    transactions.  It does this by storing the sessions on your
    filesystem.

    This update, 0.2.3, uses cPickle, which makes it faster and more
    flexible.  There are additional new features.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: BannerFolder, by "lalo"

    This product randomly displays one of it's contained ads or DTML
    Methods.  There are provisions for tracking click-thrus and for
    limiting the number of times an ad will display.

    The current version is 0.4.

    http://www.zope.org/Members/lalo/BannerFolder

  * Software Product: ZRadius, by "Zen"

    This is a Radius authenticator.  It can be used on it's own, or in
    Zope as a GenericUserFolder plug-in.  This is a bug-fix release,
    bringing the version to 1.1.

    http://www.zope.org/Members/Zen/ZRadius


Zope.org items

  * Zope Documentation Plan, by Amos Latteier

    Amos Latteier is soliciting feedback on his Zope Documentation
    Plan.  It describes the initiatives to improve the documentation
    situation which are underway at DC, their goals, and the
    assumptions they are based on.  If you would like to offer
    feedback, Amos is available at <amos@digicool.com>.

    http://www.zope.org/Members/Amos/Documentation/Plan

  * Tip: Using PythonMethods on FreeBSD, by "als"

    This tip points out that a module required by PythonMethods (new)
    is not enabled by default by FreeBSD's python port.  It describes
    the solution.

    http://www.zope.org/Members/als/tips/PythonMethod_FBSD

  * All Product Releases, by Martijn Pieters

    This page is designed to be used with wget, Go!Zilla, or some
    other web-sucking tool.  It contains links to every Product
    Release on the Zope site.

    http://www.zope.org/Members/mj/AllProds

  * How-To: Wizards Made Easy, by "jspisak"

    This document explains a few techniques which make it easy to
    create simple multiple-page forms, like Windows' Wizards.

JC,

It was intended as a self registration sandbox environment for a Birds of a
feather group at a conference.

It basically allows users to self-register and then creates an area for them
to experiment with Zope.

Most people seem to be interested in the self-registration bit tho. (which
is quite strange as this is only a few lines of a python external method,
whereas most of the code is taken up with mundane stuff).

Message-ID: <00030211041201.20388@localhost.localdomain>

Is it at all possible to have this list set reply to?

since problems discussed and solved here are logged for others to search,
surely it would be best if, by default, replies to these messages came to the
list?  I know it's just a little thing, but it still bugs me.

I know that on other lists to which I subscribe this is done.

Anyone else have an opinion on this?

    You've no doubt noticed that over the last couple of months, the
actual list content in the ZWN has dwindled to nil, excpet for
zope-announce.  :-/  I'll change that first paragraph of the ZWN next
week.

That depends on what you want the 'dynamic' content to be, and where you
want to get it from.

Perhaps the webmaster at zope.org could add a how-to search interface to
the how-to listing page? You know, one that searches only how-tos (or
how-tos and tips). Sometimes using the current search box yields lots of
not-so-useful links. :(

Don't forget that you can click on the cplum headers on the How-TO index
page to sort by that header, and a second click will reverse sort.

For example, to sort by date, click "Date".

can we really run apache without running zserver?  i've been running apache as
the frontend, and uses pcgi, but i still run zserver.  if what you say is true,
then maybe i'm doing something wrong.

My email window dies suddenly, before I could write what I intedned ...
looks like it sent itself waaay too early. Sorry.

Anyway, have you tried the batch processing instructions at
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.5.html
They should give you some insight as to how to get the first letter. You
may then be able to set a temp variable, called CurrentAnchor, for
example, that contains the last letter that was used to set an anchor.
Testing agaimst the CurrentAnchor, you should be able to set (if not the
same), or continue (if the same).

Unfortunately, ZCatalog apparently doesn't do reg-ex searches yet.
Otherwise, I'd say create your links a alink to a page that looked for
thins that started with that letter.

Alternatively, you could look at the howto, and give a range of letter,
say a-e, f-j, etc. and just use the batch processing capabilities in
DTML. :)


Just some ideas.

This may be well hashed for most here but I'm curious about this. I've
noticed that most true mailing lists operate like this zope list, whereas
the lists I subscribe to via services like eGroups perform more like Curtis
would like it. I'm with Curtis on this, it seems much simpler to just send
the reply to the list... if I hit "reply to all" the person I'm responding
to and the others that have particpated in the thread get at least two
copies... one direct and one via the list. I'd have thought that the
multi-copy thing would quite bothersome for most overloaded list-partakers.
Plus the fact that at least some of the time messages must unintentionally
never make it to the list. I can sure live with it the way it is... but can
you give me an idea why "the standard makers" thought the way they did/do?

Thanks

I think so.  A "brain" in obscure Zope parlance is a class used to enhance a
raw tabular record, such as a ZSQLMethod or ZCatalog returns.

Hmm.  Somehow you aren't getting a dictionary, then.  It's hard to tell from
just what you've posted where it's going astray.  Are you dtml-return-ing a
literal dict as in your initial posting?  How is dictionaryVariableName set?

You need to hack the z2.py file.  Go down near the bottom (look for the
string '# HTTP Server') and you will see that the HTTP server is fired
up on the IP_ADDRESS interface.  This variable is defined on line 252
and the default is an empty string '' which means, 'all interfaces'.

You can hack the code here to do anything you want, define a bunch of
interface variables, etc...

Yes, this needs to be done better, but short of comming up with a conf
file like apache and dealing with all that, it's probably no so
realistic.  z2.py is currently config'ed with command line options,
which gets out of control after a while.

Erm... since when is the reply to field of an e-mail header NOT standard?
Why is it a bad idea?  It means the default action of replying to a message on
this list is to contribute to the list.

I'm not saying you are wrong.  I just would prefer a clear explanation instead
of an outright "that is wrong."

Well, one aspect of it is summed up in two words:

	Mail Loops.

Mail loops involving mailing lists get real nastym real fast. While it
is true that most MTAs have capabilities to detect them, it is also true
few are very effective, and even fewer admins even try to enable them.

As far as the two copies aspect, I hit reply-to-all, and delete the
individual from the recipient list. Some mailers do it properly and have
group, and individual response options.
A third aspect is end-user filtering adn reporting. On lists where the
headers are munged, often the client reader doesn't display attributions
correct, or sort correctly.

I believe i mentioned that everything in my email was from my questionable
understanding of ZOPE.  However, since nobody else has said "erm.. no, that's
not correct" i'm led to believe my assumtptions were correct. (o8

Personally, I've only used ZOPE directly with ZServer, or via an Apache server
with proxying (i don't count my as yet abortive attemts with apache and fastCGI
:)

From a review of my original assumptions (and actually looking further) i may
have been totally incorrect, believing the Zope.cgi might be a program you
could simply drop into your CGI directory, and presto.

But from closer examination, and some testing, I don't belive this is true.

You still need ZServer, I think this person meant that ZServer wasn't
actually listening on any outside ports, just the local domain socket to
Apache.

FYI, Zope used to be able to run without ZServer, but it was single
threaded.  You can still do that now (I imagine) but if you want
concurency you need ZServer.

This is highly cool, is there anyplace that this, and other similar
methods are documented besides the code itself?

Subject: [Zope] how much resource?
Message-ID: <0003021244090L.00679@tokey.kedai.com.my>

hi all,
i'm happy to say that our site (www.emedia.com.my) has been running steadily
since feb.  and we got our first 1M hits per day yesterday, and zope didn't
screeched to a halt.

now i'm wondering how much resource <dtml-if> ..<dtml-call>, <dtml-in> affect
the sending out of data to users.  will a lot of if and ins bog down the
server?  i wanted to do two different page for the same contents i.e. pages
with tables, and without tables.  i intend to do as what zope.org does for
printable page where we set a variable in the url or maybe set a cookie.  to do
that, i need to have an if statement in all files looking for that particular
variable and render the apropriate header file.   will this affect response
time? i've looked at chameleon skin but could not grasp the way it works.

if anyone got better ideas, better solution, shoot it here.  thanks

Zopistas,

I notice that there are two "performance" options with Zope, proxying

The digest version is that adding a reply-to field clobbers legitimate 
reply-to headers, that many mail readers will have difficulty replying 
to the sender's address without resorting to cut and paste, and that
it renders the 'reply to all' function on most mailers useless. 

Further more, on 'reply-to' style lists it's quite common to see
replies to messages that were intended to be send to the sender end up 
on the list - to the annoyance of the list readers, and often the
embarrassment of the person replying.

This is the downside to CC style lists. One day it will piss me off
enough to write a patch for Mailman so that it won't send a message to 
a list member if they are already in the To: or CC: fields.

The Reply-To field is intended to be a way for you to indicate the
email address that you can be contacted with when the one your sending 
from doesn't necessarily receive email - ie, you're migrating between
accounts, or posting to a publicly accessible list from an account
that isn't receiving email from that list. Whatever. The point is that 
we want to keep people's reply-to fields where possible.

Yes.  Measureable in milliseconds.  It's really not that much to worry
about just doing one conditional evaluation.  What you really want to
avoid are long loops.

A reply-to field itself is not against standards, the requested _use_ 
of the reply-to field is. Slight difference ;)

[The applicable standard is RFC822.]
(of course, technically speaking, the modified subject line in this very
post is in violation of the standard, but since it doesn't tend to cause
nasty mail loops, it largely goes unnoticed :) )

> Why is it a bad idea?  It means the default action of replying to a message on

Right. Now what happens when Joe User takes a trip, and sets his 'I am
on vacation.' autoresponder on? That response is sent to everyone. That
response generates another email to him ... continue ad nauseum. Or
consider the target email being no-longer-valid. You get a mailer-daemon
response telling everyone on the list about it; which includes the
target thus generating an error which....

Granted,  when all parts of the peices of the puzzle are coded properly,
that may be reduced in frequency and/or intensity, but unfortunately,
many, many manchines are not set up properly, and software isn't coded
correctly.

See my other response. On top of those, I would add the issues with mail
<-> news gateways and loops that can/do occur as a result of improper
header munging.

Hi John -

It does make sense from those angles. If it was just me and Curtis on the
list I guess we'd still like to have it our way <g>, but that's ok. I'm sure
what Bill said about this issue having been turned over endlessly is true,
and therefore if this sort of standard has emerged it's got to the the way

OK... here is something I was talking with my workmates about.  So, i send a
message to the list from somewhere other than my list registered account.  If i
was migrating accounts, or whatever, i would change my details with the list
server.  Mailing Lists should only be sending to registered addresses, surely?

so, the list server doesn't care where the message came from (or maybe it
does), and has a FIXED LIST (as far as it's concerned) of people to forward the
messages to.  Why does it care what is in the reply-to field?


on another point that is showing in this list... Reply-To-All buttons...

having reply-to set cirvumvents ALL the problems with duplicate messages, etc.
I have the option of a) Reply-To-All, and risk doubling to someone,
OR
hitting Reply, and getting the mailing list server to send it on to everyone
appropriate.

Be warned that this is a religious topic, and that the technical
arguments presented for both sides are (arguably) easily balanced by 
the arguments from the other side.  The following URLs contains 
reasonable arguments on both sides:

  http://www.metasystema.org/essays/reply-to-useful.mhtml  

Note that there are also some good pro-reply-to arguments under the
first URL, despite its title.

A small note: Given a message with a CC list list _and_ a Reply-To
set, a group reply on Many (even most?) MUAs will send the reply to
the Reply-To and ignore the CC list (IIRC the RFC is ambiguous in
this matter).  In this manner if an individual is using Reply-To
correctly (to hide the fact that they can't receive mail at their
From: address), they are also cutting the other recipients out of
the loop for replies.

Dangerous.

Conversely, if a list does do reply-to munging, this doesn't happen,
but the "proper" address for the original post is usually lost.

This is off-topic however.

Martijn, it is not problem of timezone setting. If yes I had to see the
difference in past also. And it was OK. The problem started with
29.2. date. I think that it is a bug in bobobase_modification_time. The
system time is OK, only problems with bobobase_modification_time.

A very meek greeting..


Ok... i have now seen the error of my ways.   I fully admit i was not aware
there were so many problems to what seemed like such a simple convenience.  I'm
sure i can live with trying to remember to set the To address.

Please,  _I_ require no further conviction in this matter.  The information has
been provided as i asked (thanks to all who did), and I have been made suitably
aware of why this (and many other) list avoids using the reply-to field, for
the simple matter of 'avoiding problems'.

Hey.. by the way... has anyone else noticed the prolific nature of vagueness in
RFCs?

Its the old game:

  Only what is stated is defined.  

  Some things are stated to be "implementation dependent".

  Everything else is undefined and might involve green hairy
  martians coming out of someone's nose.  Or not.  Or both.

RFCs are a little better (or worse, YMMV) than standards documents
(which aren't really written in english per se), as they often
concentrate more on "intent" than definition.

If you're running Debian/GNU Linux, you need the python-dev package,
but then why not install the zope packages?

$ dpkg -S /usr/lib/python1.5/config/Makefile

Message-ID: <Pine.LNX.4.21.0003020306150.8576-100000@zaibach.twistedmatrix.com>

just to elaborate on a few common points that have been brought up on this
list, and covered here: 

> http://www.metasystema.org/reply-to-useful.mhtml

1) "It's against the standard":

Quoting directly from that article:

The first thing to consider is that RFC 822, the document which defines
the standards and usages for email, specifically mentions this usage in
section 4.4.3:

 A somewhat different use may be of some help to "text message
 teleconferencing" groups equipped with automatic distribution
 services:  include the address of that service in the "Reply-
 To" field of all messages submitted to the teleconference;
 then participants can "reply"  to conference submissions to
 guarantee the correct distribution of any submission of their
 own.

It's not "against" the standard.  It may be a quirk of the
standard.  Detractors, please familiarize yourselves before FUDding.

2) "It causes mail loops."

Can someone please direct me to a record of this actually happening?  
It's certainly not common, and I run all of my lists with munging on.  It
doesn't cause problems there.  Several other lists (yes, some of them are
even "real" lists) that I subscribe to use munging and have never seen a
mailloop.

3) "Autoresponders are upset by it."

If you're going to use an autoresponder, configure it responsably!  Better
yet, don't use one at all.  They are annoying.  Mail loops generated here
would happen anyway.

4) "It removes useful information."

If you're using the 'reply-to' header rather than your 'from' header to
encode the address you want responses sent to, I know this is within the
standard, but you're wasting my bandwidth and my time.  I don't need to
know both what machine you sent from and what machine you want me to reply
to.  Just put your own address in the 'from' header.  (This is what most
people do anyway.  I don't know anyone that works otherwise.)

5) "It removes freedom"

This is a crock.  Anyone with a reasonably written mailer can respond to
messages how they please: reply-to munging makes it easier to reply *only
to the list* which is almost always the required functionality.  If you
really can't live without the original reply-to header, maybe you should
consider posting a message to the list asking the person's private email
that you want to get in touch with: you should really be requesting to
take on-topic discussions off the list in the first place anyway.

Speaking of wasting my money / time, if you're going to be a detractor of
reply-to munging, PLEASE be thoughtful enough, at least, to remove the
inevitable list of 18 or 20 recipients that cruft up to threads over time.  
This 'conscientious' behavior, as described by Chip Rosenthal, has gotten
me CC:ed on some messages 2 or 3 times on unmunged mailinglists.  I find
this annoying, but less so than getting flamed for sending out 8 replies
to a single mailing-list message.  And I like to conserve bandwidth.

This is much-repeated stuff, but I hate to think that there's this image
that technically sophistocated people all hate munging and think it's
evil.  Chip's opinion is, as the author of the essay referenced above has
told me, treated as gospel, and there are definitely two views on this
topic.  I strongly adhere to one, obviously. :-)

(Please, no flames, no personal email about this.  I'm not going to be
convinced of anything, this is just a message to make sure that 'newbies'
to list administration don't think that there is one answer to this
question.  It's not really for those of you who seriously consider munging
bad, and I certainly don't hope to get the policy on this list changed by
it; that would only spark more discussion of this, and one extra email
once in a while isn't so bad compared to thousands upon thousands of
messages in this thread... ^_^)

Hi,

Can you please tell us what is the configuration of your machine.  I am
very interested.  We had our servers crawl to halt when we used Zope but
we had other things running at the same time.  So I will appretiate it if
you can give us the configuration.  Are you using a database? Is it on the
same machine or by itself, and if so what are the configuration of the
supporitng servers.

1M pages/day is a great number, I think that if a farm configuration is
used you can create an extremely dynamic and scalable site.

TIA
Adonis

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.


[RH] Um, without plugging my own document, you may want to check out my
'Changing Contexts in Zope'; reading your post it may be what you want. It
is not (meant as) a howto, but a bit more general. It should go into in the
ZBook of ZDP (watch this list for announcements about ZDP rsn). In the
meantime it is available from my member page:

In addition to the valid uses posted otherwise ...

Real life example:
 At work, I am within a corporate firewall. On my unixen, my email
address is local to the machine, ie. bill@somehostname.bigcorp.com. If
you reply to that, you will be wasting your time and badwidth, since you
_can't_ access it from outside the firewall. Thus, I (in this example)
add a reply-to that has a _useable_ email address, ie. one avaiable to
you, form outside the firewall. I personally know of several hundred
people who do this, and several thousand who _should_ be. And before you
say it, no, not every mailer lets you set the 'from' header.


The point? Now you know someone who uses it. ;^)

How can this be on topic, you ask? Read on. :)

I've notice a certain increase in the amount of 'sending mass email with
zope' messages lately, and not many solutions.

Since I don't zope on windows, one method I have used when wanting to
avoid the sendmail tag (I _was_ having problems with the friggin thing
not working), was to shell out and call mail (or mailx, depending on
your *nix) to send each message. Problem was, when doing that, the
'from' address was 'nobody@foo.bar.com'. Since I wanted replies, I had
to add the reply-to to get a response that was useful.

(Hey, I din't say it was a strong effort to bring it back on topic for
the list :)
Perhaps those wanting to send out mass emails *cough*spam*cough* with
zope, and not finding answers from within Zope and the sendlmail tag
(yeah, I still look at that puppy with suspicion and a sneer :) may see
this as an option

hi, we have a PIII 500 M, dual processor running rh6.1 with 712M RAM.  there's
only zope there, and mysql to cater for banner ads.  i'm using phpAds for now
until we got a commercial ad server or until there exist a mature banner ad
products for zope. (i'mm eyeing banner ad with interest tho..)  everything is
in one server, although we're looking at adding another server for redundency. 
don't know yet how to go about this.  anybody got any pointers?  maybe
failoverd? (http://ps-ax.com/failoverd/ ) or eddie?(www.eddieware.org)

the 1M number is hits, not pages.  we have max 600k pages/day last  feb.  this
is our second month so, hopefully zope lives up to its standard.. or i'll need
to find another job *grin*

I only noticed it today (2000/03/02): the undo logs show
2000/03/01, and so do ZWiki times. This appears to be a bug in
bobobase_modification_time.

<dtml-var "_.DateTime()"> does show the right time, and the 'Content
changed' notification Zope gives does too. The bug happens on both
Windows NT and Linux.

Martijn

Thankyou.
However,to help my understanding how does this work?

Hope you don't mind - I've mailed my other, unanswered

In the depths of a tree tag I want to pick up a

if the property isn't present.

This code seems to work when used not in a tree tag
but when its in a tree tag it still finds the property

What gives? How can I do this?

The version below doesn't fall over if the property
isn't present on that object, it just finds it by acq.

To fully round out this little performance study (small study of 
course) could you tell us what capacity the machine is at as far as 
you know, what Zope version you are running and with what 
configuration (Zserver alone, w/ Apache etc)?

These kinds of things are really helpful in determining Zope's 
ability to scale and in winning out the hearts of iCEO's.

Martijn, it is not problem of timezone setting. If yes I had to see the
difference in past also. And it was OK. The problem started with
29.2. date. I think that it is a bug in bobobase_modification_time. The
system time is OK, only problems with bobobase_modification_time.

The best test is creating a DTML _Document_ (not a Method!), with the
contents:

  Modified: <dtml-var bobobase_modification_time><BR>

Subject: [Zope] Problems installing Zope
Message-ID: <38BE54C2.B71E007E@rdel.co.uk>

Having just successfully installed and setup Zope and Squishdot
on an 486 Linux box (Debian packages made it dead easy), I
thought I'd move over to a SUN box as it is quicker and I want to
run a discussion group for the intranet here.

[SunOS 5.5.1 Generic sun4m sparc SUNW,SPARCstation-10]

After installing the latest python (and then re-compiling with
threads, doh) I unpacked Zope-2.1.4-src and ran wo_pcgi.py.
Everything seemed to go fine, so I simply fired it up using
./start. After a couple of seconds Zope (okay, Python) falls over
reporting that the ExtensionClass module couldn't be found at the
import in ZODB/__init__.py.

Actually, after investigation, none of the modules would load
from an import even though they all have .so files present in the
lib/python dir. Now, I don't know a thing about Python so I don't
know where to look to sort this out... Any ideas?

Is it something to do with shared libraries being handled wrongly
on SunOS 5?

Only other thing I can think of is search paths. I install
outside of /usr, but I can't imagine that would be a problem. Do
I need to set a PYTHONPATH or something?

Help...

I've put this into the collector, the bug is a bit weird for those, who
use bobobase_modification_time quite heavy, like me :)

aah .. the 'content changed' is a bit irritating, but it's only the
notice 'content changed' and a <dtml-var DateTime> in the next line.

Thanks,

Okay, my code was unclear in the example (though with a new created
method the modification time of the container should have changed too:),
but I'm quite sure, it's a bug.

Or, as someone else pointed out, you could use the -a parameter to z2.py.

Just run z2.py --usage for all command line options.

Uuuhhhmmm.. <g>

I just tested this myself. Here's my output:

   Modified: 2000/03/01 13:06:16.05 GMT+1
   Current time: 2000/03/02 13:06:17.86 GMT+1

Heh. One day off. And so is the Undo log.

My apologies for my unduly applied sceptisism. I'll go and hide now, and
investigate.

   I have Zope installed and running on Sun Sparc Solaris 2.5.1. Zope is in
/usr/local/Zope. There are 17 .so libraries in lib/python. Zope is running
fine: http://sun.med.ru/~zphd/
   The only thing - I am running under Apache with PCGI, no ZServer.
Nothing special for dynamic linking...

Or use CVS load_site which has a -I feature that for every index.html

Apologies for the late reply - flu :(

Yes. I create a DBH in an EM and fire away. All I get from the Zope 
system is a request of the form http://supercascade?root_id=240551 
and I start to do my queries. They are nested in the EM to 9 levels 
deep (but normally the first 4 levels are enough to get all the nodes 
of the tree with the relevant root_id). Getting the list of nodes is 
quite fast, about 0.8 seconds. Then I have to render them. I've got 
that down by a factor of ten (since this thread has started in actual 
fact!)

I've also found out just how fast a cached ZSQL method can be - one 
DMTL method that used query took 3.2 seconds on the first render, and 
0.06 seconds on subsequent renders. Obviously some more work needs to 
be done in this area and I'm looking into that.

I'm also told that our MySQL server itself does some caching ... 
looking into that.

Ah, I hadn't thought of that...my query isn't recursive however.

Dunno if this is related or not, but I got some really weird errors yesterday
when trying to view some images I had created in Zope on the 29th.

All I was trying to do was view them using the image's view tab and I got a Zope
error. Something about an invalid datetime stamp I think but try simulating it
yourself if you want the exact answer...
They also appeared as broken images when I included them on pages using
<dtml-var image>

so, Zope doesn't like leap years? ;-)

A little while back I uploaded a patch to the ODBC Database Adaptor

Indeed it did, but unfortunately it broke a host of other things.

Anyone who downloaded the patch the first time around may be

Does anyone know the inner working well enough to tell me whether or 
not Zope actually makes two separate calls to the database or whether 
it makes one caches it and uses the results twice?

If you know and would like to expand on how Zope deals with caching 
SQL data that would be great I am trying to optimize my Zope

Hi,

Can anyone tell me what are the predefined error types
for the <dtml-raise type=...> tag, and how to use them?
The DTML manual talks about "Unauthorized", and
"Redirect", but doesn't give any details. I haven't found
how to use "Redirect" so far.

Thanks,

Stefan.

Dunno about raise, but if you want to do a redirect, try (untested,YMMV,etc)

<dtml-call "RESPONSE.redirect(url)">

Perhaps its an architecure-related bug -

Here's what I've got.  First, I have a DTMLMethod named creditCardsAccepted 
which is defined as follows:

<dtml-return "
{
'Visa':'V',
'Mastercard':'MC',
'American Express':'AE',
'Diners Club':'DC',
'Discover':'DS',
'Carte Blanche:'CB',
'Japanese Credit Bureau':'JCB',
'Transmedia':'T'
}">

I then have a method called creditCardSelections which is defined as follows:

<dtml-return "creditCardsAccepted.keys()">

(I also tried <dtml-return "_['creditCardsAccepted'].keys()">)

When I try to "view" my creditCardSelections, I get the attribute error on 
'keys'.

Just tried that, same results (keys error).

(BTW, there was a typo in my message describing the dictionary I was 
returning.  The typo existed only in the e-mail, not in the actual code)

Hi!

Can anybody tell me anything about subclassing a UserObject?
I have had some neat errors (including seg-faults and indefinite loops by just subclassing a ZClass from User Object)
When I tried to insantiate a Subclass of UserObject Zope quit.
(I did not change anything to the default constructors and expected something like "missing argument", but not an indefinite loop :)

I am using Zope 2.1.4 on Linux/x86 (2.2.13)

Thanks.

Followup,

I just realized that I had two definitions of "creditCardsAccepted".  One 
was defined inside my ZClass, and one was defined in the folder containing 
the ZClass.  The one in the container was just answering a list.  When I 
changed that one to answer a dictionary things worked.  I then simply 
deleted the DTMLMethod in the containing folder and now I get a name 
error.  Now I'm really confused.  After deleting the higher level method, I 
now have the creditCardsAccepted and the creditCardSelections both in the 
same folder.  It seems, however, that the creditCardSelections cannot see 
the sibling method.

I'm clearly overlooking something.

Andy,

Do all of the objects have a property 'rubbish'?

Try something like:

<dtml-with aq_explicit only>
  <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
</dtml-with>

This should check that the rubbish property exists and change what gets
rendered depending on that.

J,

In the advanced tab on the edit page of a SQL Method there is a entry box
for caching information.

You could start by looking there.

Phil,

> Do all of the objects have a property 'rubbish'?

No, only some of them.  The problem goes away if
I make sure that every object has some value for
this property but that's not a good solution.  The
code you suggest (the dtml-if ...) is exactly what I intended
but on my system (Linux slackware 7 + zope  2.1.4) it finds
higher level rubbish properties.  Actually its not really
called rubbish, that's just what I was using to check
it worked before using it.

It simply doesn't work - if it works for you lets find
out what's different.  Are you on a windows platform?
What Zope version?

Just to restate the problem for new readers:-

The problem is to use "dtml-with X only" inside a tree rendering
so as to be able to test whether the current object
has some specific property.  The code works outside trees but
used in a tree it still seems to find properties by
acquisition.


> Try something like:
> 
> <dtml-with aq_explicit only>
>   <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
> </dtml-with>


This code finds "rubbish" at higher acquisition levels.  I know it
shouldn't but it does.  Anyone throw any light on it?

Andy,

Hmm, I'm confused.

I use this 'trick' all the time, here's a bit of code from a method of mine:

<dtml-with aq_explicit only>
    <dtml-if url>
      <a href="<dtml-var url>" title="<dtml-if status><dtml-var
status></dtml-if>" target=main><dtml-var ident></a>
    <dtml-else>
      <dtml-var ident>
    </dtml-if>
</dtml-with>

Which works beautifully.

Hmmm

confusion reigns!??!

Phil

Subject: [Zope] urgent! help! strange blockings
Message-ID: <38BE960E.32E0F12E@wildenhain.de>

Hello,

I cannot get ride of those strange blockings of zope.
This happens from time to time and leads some times to
minutes without action from Zope.
I increased threads pool and decreased it, I use a much
bigger object cache (memory is not an issue on the machine)
and I pured the database (with help of an extra machine)
Zope stucks with about 18% processor use and does almost
nothing at the moment.

Any posibility for an dead-lock?

Help is very appreciated!

Configuration: Zope 2.1.4, ZODBC, Database-Size: 66MB (after purify)
Some sessions with unsafed work, 50 threads for pool, NT 4.0 (ok, this
sux, 
but we have to use ODBC with strange Databases)

I posted a message about this this morning. In effect, yes you can 
use caching and it is veery fast (one second and subsequent renders). 
For your document, I think you'll find it will speed up by a factor

ps it's the 'Advanced' tag. Put something in the 'cache results for n

Andy,

I sent before reading all your mail.

This technique works on NT and a Linux box both running 2.1.4.

I've tried to do something like you suggested, but it doesn't seem to 
work.  I'm probably not doing things quite correctly.  I've added a 
"getAnchorCharacter" method to my ZClass which correctly answers the 
character I want to use as an anchor.  I've tested this and know that it 
works.  I tried using "<dtml-if sequence-first-getAnchorCharacter> ...", 
but got no result.  Could you explain a bit more about how something like 
"sequence-first-xxx" works?  I haven't found any information on this form 
of a dtml-in variable.  Perhaps I'm just misunderstanding your solution.

In thinking about this solution, it seems that if I'm inside of a dtml-in 
iterating over entries in a Catalog, the objects known to the "dtml-in" 
aren't instances of my ZClass, but instances of some catalogging wrapper 
for my ZClass.  Therefore, it would seem that my getAnchorCharacter method 
wouldn't be accessible from within the dtml-in, but only from within a 
dtml-with which sets the object to be the object referenced by the catalog 
entry.

Can you clarify all this?

Thanks.

No light, no solution, only a bad workaround:

<dtml-let temp_rubbish=rubbish>
  <dtml-tree ...> # your tree code
  ...
    <dtml-if "rubbish <> temp_rubbish">
      <dtml-var rubbish>
    </dtml-if>
 ...
 </dtml-tree>
</dtml-let>

Check the Grouping Variables subsection of
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.html

I did give you the wrong syntax; it's <dtml-if first-getAnchorCharacter>,
with no "sequence-".

I misunderstood you.  The catalog wrapper is the "brain" which needs to have
the getAnchorCharacter method.  But... Suppose you add getAnchorCharacter as
a catalogued meta_type in your Catalog?  I think that would work.

Subject: [Zope] ZOPE!  I HATE YOU!
Message-ID: <20000302105256.A23108@devware.com>

It used to be that I was so open minded when it came to web
technologies.  I used to say "Oh yeah, pick whatever you want, we can
do it in that."  I used to say "No problem!  We can use your scripting
technology!  It's just as good as any other."  And I would, and they
would, and we did.  And we'd all stand around and say "Yeah
man... that's cool."

And then Zope entered my life.  And NOW I simply can't think of
virtually any project that Zope wouldn't do a better job of serving
than those *other* technologies.  It's very frustrating when every
time you see a project you think "Oh, Zope would make that SO much
easier!"  Especially any time someone mentions the word "Database" and
"Web" in close proximity.  The truly frustrating part is staying
focused on the problem-space when you have such a fun technology to
play with.

Now in some ways I'll admit, this is an exaggeration.  Obviously,
there ARE lots of cases when Zope isn't appropriate, but I just wanted
to shout out a big thanks for developing such an awesome system that
makes developing apps so easy to do.  Now if I could just get my mind
off of it's possibilities long enough to evaluate those OTHER
technologies objectively, then I'd be in good shape. ;D

Message-ID: <200003021716.MAA27689@amarok.cnri.reston.va.us>

I've made a new release of Oedipus, a Python package for presenting
data from the Open Directory Project.  
 
http://www.mems-exchange.org/software/python/oedipus/   

In v0.06, The improvements to the ODP code itself are pretty minor.
The major milestone is that, after some diligent sleuthing,
Jean-Claude Wippler tracked down an obscure bug in MetaKit that I was
tripping over.  A patch for MetaKit 2.0 is included in Oedipus 0.06,
so for the first time you can actually handle a complete ODP dump.
You'd better have 400Mb of disk space for the resulting data file,
though, plus 500Mb for the source XML files, plus 4-5 hours of
processing time (at least on a 550MHz Linux box).

The exported ZClass product still doesn't seem to work, though; if you
untar it in a new Zope installation, no Product is added when you
start up Zope.  Anyone else notice this problem?

Me too, I think. I haven't investigated this more deeply yet
but I noticed that all new News items created since March 1 in
the PTK portal I've been playing with get their
dates set back to 29 Feb the moment they are modified
(by being approved, for example).

Hello all -

I am unable to connect to my Zope 2.
I am running Linux 2.2.14, with Apache
I am new to Zope and pretty new to Linux

I installed Python 1.5.2, then installed Zope using "python w_pcgi.py"
I entered ./start
It worked...  for a while... until I shutdown...
When I restarted, Zope wasn't available.  I went back to the Zope directory
and tried ./start again but the script seems to lock up after displaying the

I was so happy when I got it running, now I'm incredibly frustrated!  Please

I can supply my Apache conf files if necessary...

apologies, ignore my pervious posting, try instead:

<dtml-let newid=id>
  <dtml-with "_[newid]" only>
  <dtml-if rubbish>
   <dtml-var rubbish>
  </dtml-if>

Subject: [Zope] [Newbie]  SQL database support on NT
Message-ID: <NDBBLMHEELDKLGHEEMJPIEMMCBAA.bac@ivc.com>

Hello All:

I'm just beginning to play with zope and really like what I see.  No Zen yet
but it's coming.

The project I'm working on must use NT as the server, much to my
displeasure.  I need to select a SQL database for the project and need to
find one that will work and play well with zope.  Searching through the
Guides and How-to's has left me a big puzzled.

Looking at the "Database Adapter Roadmap", it looks like there isn't a

It looks like you are indeed running the query multiple times. Unless you
are changing the data at some point internal to the process, which would
require your to "refresh" the results in order to have current data, you
could try:

<dtml-in sqlMethod query=start_query>
Do some stuff
Do some more stuff
Do even more stuff
</dtml-in>

Youd be "recycling" the result set, and sparing the DB backend.

I'll give that a try.  If I wanted to add a method to the catalog wrapper, 
is there a non-invasive way to do this or would I have to modify some 
standard Zope code to work differently?

Thanks.

We have been running an in house (approxiamately 100 users) contact management and order process site on NT 4.0 for several months
now using Visual FoxPro as the back end database (on a different NT machine) via ODBC and have had few problems. The zope machine is
a dell P3-400 w/256megs of ram. The db machine is a generic P2-200 with 512megs of ram. They are connected through a 100mbits
intelligent switch. However both machines now have dual port 100 mbits cards and we are in the processs of using the extra port on
each card to direct connect the 2 machine.

Our application is db intensive (every sql method involves at least 1 wrapper call to determine the AUTHENTICATED_USER's access
level) Unless there is network congestion and can display an order form (2 frames each the result of 5 to 10 sql methods) in about 2
to 3 seconds. (Response is 3 to 6 times faster via browser and ZOPE than throught the VFP apps that were originallly written to 2
this. )

VFP makes a very fast backend because if you are using only indexed columns and/or expressions the it can determine the record or
records entirely from the indexes meaning it never pulls data out of  the data file till it knows exactly which records to get.
Single record lookups - even with complex queries - are almost instantaneous.

Subject: [Zope] [Newbie] SQL database support on NT


Hello All:

I'm just beginning to play with zope and really like what I see.  No Zen yet
but it's coming.

The project I'm working on must use NT as the server, much to my
displeasure.  I need to select a SQL database for the project and need to
find one that will work and play well with zope.  Searching through the
Guides and How-to's has left me a big puzzled.

Looking at the "Database Adapter Roadmap", it looks like there isn't a
direct adapter for SQLServer.  is this correct?  Will the Oracle adapter
work on NT?

If not, is my only choice to use the ODBC adapter?  Or the ZJetAdapter for
MS-Access (which I don't think would be sufficient for my needs)?

Any suggestions for database selection on NT will be appreciated.

Thanks,

Brad

LoginManager now has this capability. The loginForm is passed
"needroles", the list of roles one would have to have one of to perform
the action that prompted the login. Thus you could do:

 <dtml-if "'Member' in needroles">
  ... member login form ...
 <dtml-else>
  ... manager login form ...
 </dtml-if>

(note that 'Manager' is likely allowed to do both member and manager
things, and thus checking "'Manager' in needroles" would be true in
either case and not do what you want)

Hey guys. 

I'm currently in a minor bidding war with the Oracle group here over
whether we re-implement some intranet programs in Zope or in Oracle
WebDB. I've got them on just about everything, except calling stored
procedures. 
Now, I know that ZOracleDA supports Stored Procedures. So I'm guessing
that something like the following would work, but I'll be buggered if I
can figure out how. 

ZOracleDA Connection : oracle_da
External Method : find_target(search_string)
Oracle Package : Program1
Oracle Procedure : Proc1

def find_target(self, search_string):
  c=self.oracle_da.cursor()
  s=self.oracle_da.procedures.Program1.Proc1(search_string,c)
  return c.fetchall()

Am I missing something? I can't even get -- 
>>> import DCOracle
>>> dbh=DCOracle.Connect('user/pass@DB1')
>>> c=dbh.cursor()
>>> sth=dbh.procedures.pgm1_api.find_target('spam',c)

Subject: [Zope] SQLSession and Performance issues
Message-ID: <38BEDC9C.734F4754@exceptionalminds.com>

Hi all,

I have a form on which I am having some interesting performance issues,
I think, but am not sure that it is my extensive use of SQLSession
variables throughout the form.

I have a single page data entry form where almost every field  gets
stored in the SESSION. This form can take from 9 to 15 seconds to
display. When all my other forms take 1 to 3 seconds this is a
significant slowdown.

I am curious as to what methods may be used to reduce calls to
SESSION['varname'], or if I am even barking up the right tree.

Thanks.

In the 'utilities' directory of Zope there is a tool called

ok.  by "a ZODB" do you mean that the call in my external method
is trying to reopen the ZODB zope is using?  i'd assumed i was 
crating another one, with a separate FileStorage.

ok, then how does code in my external method get at that?
that is, how do i create an object and stuff it in the DB?
all the code examples i've seen follow the pattern in GetPeople().

how do i do this?

i get the feeling i'm just missing something, perhaps thinking like
a python programmer rather than a zope guru.  i feel like there's 
some big obvious point that has escaped me, and i'm waiting for the
big "AHA!".

so, one more try.  given the following external method:

import ZODB, ZODB.FileStorage


def GetPeople( self ):
	"Return list of people in DB"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( 'TestDB.fs' ) )
	connection = db.open()
	root = connection.root()
	people = []
	for key in root.keys():
		people.append( root[ key ] )
	return people

if __name__ == '__main__':
	for person in GetPeople( None ):
		print person.name, 'is', person.age, 'years old'


referenced from a DTML Method:

<dtml-in "GetPeople()">
	<dtml-var name> is <dtml-var age> years old.<br>
</dtml-in>

when i restart zope and view the method, it works once, but shows
no persons.  the second time, it fails with the traceback.

what do i change to make it work?

thank you for your patience.

I have not followed the thread but reading this particular posting, seems
to me that you cannot do what you want to do (at least in a
straightforward way). Importing ZODB declares all kind of global
variables/methods, an important one being get_transaction() which returns
the current transaction. So if you do a get-transaction() in your external
method which transaction should it return? And how would the two
transaction managers interact? Couldn't you just register your root object
with the current ZODB (the one Zope is running), by just setting it as an
attribute to the root object?

Again I have not followed the thread so I may be way off topic.

Thanks for investigating this - because TimeStamp objects are 
used in the object database, I don't want to make any changes 
to this yet until I can talk to Jim and verify that the fix 
won't have any impact on ZODB code (mon. morning probably).

Last I checked, setting an SESSIOn variable immediately did an update
on the RDBM which would explain the slowdown. I do not know what the
current situation is but I remember Anthony mentioning he was thinking of
changing it. You might trying playing with the source code and store all
changes to SESSION in a volatile attribute and call the SQL method at the
end of the transaction only (at least this is how I do it in FSSession).

The Oracle adapter will work but not with SQL-server.

Your only choice is the ODBC adapter if you want tyo use SQL-server.
We're running Zope on a NT server with SQL-server as database.
It works very well.

Thanks... but I think I really need to raise an error:
I want to invoke the redirect in the standard_html_header,
so if I use <dtml-call "RESPONSE.redirect(url)">, only
the header will be redirected (I think...).

Another, slightly related question: On my zope, whenever 
there is an error, the whole Traceback is printed on
the error page, and this doesn't seem to be part of the
standard_error_message. Does anyone know how to hide it,
or to put it in a html comment, like www.zope.org does?

Thanks,

Stefan.

If a FieldIndex is treated as atomic, it shouldn't go trough
the Splitter, right?

I found out that an hyphen in a field indexed as FieldIndex
breaks the index (this field is just not indexed, it seems). A
space works. Weird.

I was working with my ZClasses today and was confronted with something 
which seems strange.  I was editing a method defined in my ZClass when I 
tried to click on the "propertysheets" link displayed at the top of the 
edit screen:

DTMLMethod at  / ControlPanel / Products / <product> / <zclass> / 
propertysheets / methods / <method name>

When I clicked on the link, a basic authorization dialog was displayed.  I 
was already logged in as the superuser.  Why am I getting an authorization 
dialog?

Mostly just curious.

Thanks.

I guess it depends on what database you are using. If your
database is a remote server hooked up through TCP/IP port,
too many calls to SESSION could be bad. Also, if the session
data is large, during the transimission many packets have to
be send.

I don't have an answer... maybe you could describe first
what database you are using (Gadfly on the same machine?
remote database?), do you do many retrievals and updates?

------------------------

In the code SQLSession.py, there is a 'caching' variable.
SQLSession seems to cache variables that are already
retrieved or are recently updated. Try to set 'caching'
to 1 and see if that helps.

------------------------

As Pavlos Christoforou said, another strategy is to
have a single session data variable (a dictionary,
for instance), and then retrieve it, say, in your
standard_html_header and store it in your standard_html_footer
(or their equivalents.) This way you only need to access
the database twice per request.

------------------------

Please post back... I am also very interested. You
can also time performance by calling time.time()
in Python or <dtml-var ZopeTime> in DTML. I am
curious in the source of the problem... It would be
nice to find out whether the time is spent in each
database query or in TCP/IP packet splitting/joining/waiting.

Hung Jung

PostgreSQL running on the same box as ZServer.

Thanks for this input. I will go and take a look at it. I did not know
it was there.

Now this in an interesting idea, but all my attempts to computationally
build a dictionary within Zope have gone to naught. I would love any
advice on this as I believe it could very well be the key to this
problem.

This will redirect the whole page, as it gives a client-side redirect.

it only does this if you're logged in, otherwise it puts it in a comment

This ist a typical Y2K bug, located in the module TimpeStamp.c,

Since nobody followed my hint from earlier this day so far, I took

changing the leap yar calculation

 l = y%4==0 && (y%100 != 0 || y%400==0);

to

 l = y%4==0 && (y%100 != 0 || (y+1900)%400==0);

in that function fixed the problem on my system.

erm.. one question... are you running Squid?  Or anything else on port 8080?

try "telnet 192.168.1.100 8080" and see what it says.


p.s.  if you want ZOPE to start on bootup, i put this in my /etc/rc.d/rc.local
file (I'm running RH6.2.. your rc.local may be elsewhere, or a different name):

/usr/local/Zope-2.1.3-src/start &

I actually run ZOPE as user 'zope', so i use:

su -l zope --command=/usr/local/Zope-2.1.3-src/start &

Have a better one,

This is the detail I did not notice, previously. I thought you were trying
to store objects in your Zope ZODB; I didn't notice that the filename you
were passing to FileStorage was not Data.fs.

I don't understand why the problem is manifesting as it is, but I got your
code to work by modifying your code as follows:

- for key in root.keys():
-         people.append(root[key])
+ connection.close()
- return people

Opening a connection without closing it is a Bad Idea. I just can't figure
out what this has to do with the lock file on the database. I figured when
I closed the connection it was deleting the lock, but this is not so. So,
I remain confused. ;-)

Hope this helps!

That's why I didn't suggest a fix in my first analysis. I don't know 
anything about the internals of the Zope object data base (hey, I 
learned about Zope only about two months ago, so what do you 
expect?). So I don't even know whether it's just a problem of 
displaying the wrong date, or whether wrong time stamps are 
written to the data base. In the latter case, most people would 
prefer to have that bug fix yesterday. Inconsistent dates in a data 
base are a serious problem, and it's getting worse as longer it lasts.

okey dokey.  the setup is not that big.  we're just starting out and are just
feeling our way here.  what we have:

a PIII 500 M compaq 5500 ,smartscsi with RH 6.1, zope 2.1.3. i tried running
zserver with fast cgi but it choked with high load.  so, in the end, it's
apache with pcgi.  so far, it handles all the traffic beautifully.

what we want, however - reliability, availability of our site, so that's where
we need to look now.  caching is also another matter.  currently we enabled
apache expire module, but  not quite sure whether that would have any effect on
pages served by zope.

yes, and are you going to use sql in the future?  or just stay with zodb?  i
would think going with sql is better in the sense that most of us have that 2G
fs limit, and putting data in sql would help separate data from zodb.

Hmm. ZClass products aren't automagically imported; when exported, turn into
zexp files, either on the client machine somewhere or in the server's
$ZOPE_HOME/var directory.  To install them on another server, on must:

  * copy the *.zexp file into the new server's $ZOPE_HOME/import directory

  * import the *.zexp file into the "Control Panel | Products" folder.

You don't have to restart the new server, either, unlike "normal" Python
products.

Unless somebody borrowed Guido's time machine and retrofitted Butch Landigan's
ZPack proposal, that is?

Tres.

Greetings.

To start imapd should be set to run vie inetd. In the /usr/doc/packages/pop
directory look at the BUILD file. This has the information for setting up
inetd.conf to work with the imapd. In short you need to edit a few lines of the
inetd that comes with SuSE. Mostly you will need to uncomment the imap lines
they should look like this:

imap2   stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/imapd
pop3    stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/ipop3d

This will allow you to use the imap server or the pop server if you want to.

You may also want to check your configuration with a regular IMAP compatible
mail client like Netscape Messinger. FWIW I'm running WorldPilot on my test
server that is SuSE 6.2 (upgraded from 6.0) and works well.

Good Luck!
Jack

I checked my /etc/services file and it isn't showing anything connected to
port 8080.  Is there somewhere else I need to check?

//
// try "telnet 192.168.1.100 8080" and see what it says.
It says: "telnet: Unable to connect to remote host: Connection refused"

Then I added the "/usr/local/Zope-2.1.3-src/start &" line to my
/etc/rc.d/rc.local file, rebooted, did a "ps -ax" to see what processes were
running, saw that "z2.py -D" (in there 2 times).

So, I tried to telnet in agian and this time it said "Connected to
192.168.1.100"

Next I tried to connect to "http://192.168.1.100:8080/manage" with my
browser...

IT WORKED!!!!

Thanks a million Curtis!  I guess I just needed to add the line to my
/etc/rc.d/rc.local file and reboot!  YAY!

OK, now I need to get to work.

/etc/services is mostly just a reference list of what the port number is

that means there's nothing there to accept the connection.

yes.  Because ZOPE threads, you will see a number of them about.  This is
normal.

hey... no problem... glad i could help.

that script file gets executed every time you boot up, right at the end.  That
line just starts zope, and backgrounds it.

I have an html document that I created outside the Zope env. that has a

is white. I can see the work I have done fine when I look at the
document in Netscape, but when I load it into zope and look at it, the
bgcolor for the table column isn't there. Am I doing something wrong, or
is this a zope feature?

Hi,

What is the difference between <dtml-call "...."> and <dtml-call ...>.  For
instance, if I have this directory structure:

|
+-base
    +-subfolder

from base,

<dtml-call subfolder.manage_addFolder(...)> doesn't add any folders, while
<dtml-call "subfolder.manage_addFolder(...)"> behaves as expected. It took
about an hour of experimenting before getting this right. Could someone
explain what is the difference here?

Thanks.

I would like to understand the source of your problem, too.

However, I think there is a misunderstanding here. In TM.py,
_registered is a class data attribute, which is typically
a trick for "initializing" Python instance data attribute.
That is, unless you explicitly do something like

  TM._register = 1

the class variable would never change. That is, TM._register
is always None. Always always. So there should not be any
problem in thread interference.

If x is an instance of TM (or an instance that has TM as
an interface, in the case of multiple inheritance), if you
look at the dictionary of x, i.e: x.__dict__ , you will see
that initially x does not have an attribute _register in
its own dictionary. However, x._register is a valid reference,
because it borrows from the class attribute. The statement:

  print x._register

would print out 'None'. As soon as you assign a value to

  x._register = 1

you create an attribute in the dictionary of x. That is, a
new item is added into x.__dict__ , which is totatally
independent of TM._register. So TM._register remains as None.

I'd like to take a look into it, too. But first I'll have
to learn what the flags _v_registered and _register mean. :(
I don't even understand what is a "transaction" in the sense
used by the transaction manager.

If I understand correctly, the definition of "transaction"
that you would like to use is one single HTTP transaction,
which lasts from the beginning of a foreign HTTP client
request till the end of Zope sending out the reply.

The question is: is this the same definition of "transaction"
as used by the transaction manager? Why would anything be
stored in ZODB?!? The HTTP "transaction" should not have
anything to do with ZODB database "transaction". The
"versions" that are stored in ZODB, are they FSSESSION
objects?

I'd like to look into all this. :)

regards,

Hung Jung

Calling tags with and without quotes follows mostly the same convention
throughout Zope. A tag without quotes, such as:

  <dtml-var myMethod>

is equivalent to:

  <dtml-var name=myMethod>

This says, "Include the variable with the name myMethod." The alternate
form is:

  <dtml-var "myMethod()">

which is equivalent to:

<dtml-var expr="myMethod()">

This says, "Include the result of the Python expression in quotes,
myMethod()."

In your specific case, dtml-call without quotes is equivalent to
using the name form, and thus does nothing. There is no attribute or
method called subfolder.manage_addFolder(...). Note that Zope would be
looking for this, literally, and would not interpret the period as an
application of a method to an instance.

Using the dtml-call tag with quotes is equivalent to the expr form, and
will thus interpret the period appropriately.

To convince yourself that this is the case, try including a DTML Method
using the expr form without parenthesis:

  <dtml-var expr="myMethod">

puts this in the response:

  <function myMethod at 8071cf8>

If you view this in a browser, you will not see it because your browser
will try and interpret it as a <function ...> tag, which, of course, does
not exist.

From my tests I am pretty sure the right dates are stored. It is just the
timeTime() representation of those dates that is wrong.

However, as you pointed out, the methods that provide the representation are
a bit confused over what format the year portion should be in when called.
This,and the fact its something so deeply part of the ZODB makes a fix
something that Jim can do.. =)

Message-ID: <00030318264705.22345@localhost.localdomain>

Again, greetings...

So I kept looking at what I had, and some things just did NOT look right.

So I fiddled.  I wrangled.  I bashed it with various bits of office equipment. 
And I got it to work!

here is a cutdown of what i used:

    <dtml-in "somQueryHere" size=5 start=qs>
      <dtml-if sequence-start>
        <dtml-if previous-sequence>
          <tr><td colspan="2"><a href="past_orders?qs=<dtml-var previous-sequence-start-index>">
              Previous <dtml-var previous-sequence-size> orders.</a></td>     
          </tr>
        </dtml-if>
       </dtml-if>
      <tr><td>STUFF</td>
          <td>FROM</td>
          <td>ITERATED</td>
          <td>QUERY</td>
          <td>HERE</td>
      </tr>
      <dtml-if sequence-end>
        <dtml-if next-sequence>
          <tr><td colspan="5"><a href="past_orders?qs=<dtml-var next-sequence-start-index>">
              Next <dtml-var next-sequence-size> orders.</a></td>
          </tr>
        </dtml-if>
      </dtml-if>
    </dtml-in>

it's much simpler than the example in the DTML book (IMHO), and it would be
faster in making only ONE call to whatever query it is you're using, not 3.

I'm not sure who is in charge of the DTML reference manual, but if i get a
moment i will be forwarding this code snippet on to them.

I think it worth to encourage zopelist to move more things to the
client-side by modify a Zope fresh installation.

I found out there are many things hard-coded in
python or dtml in zope's source.

There are some things which can be do better in the client side. For
example, there were many dynamic folder tree writen in javascript which can
be more responsible than the zope tree tag (which the change of the tree
state require the help from server).

I would like to urge zopelists to explorer the client side authoring which
could actually give zope a dramatically change.

1. Remove those hard-coded parameters from the source and placed them in the
folder tree as attributes which can be modified or overwrited by manage
interface and acquisition.

2. Define the basic css (which zope.org have one) as default elements with
the fress zope install.

3. Make the current Zope tag comply with xml standards : they should end
with /> or accept an end tag.

4. Collect open-source javascript codes and convert them into zope products
(like tree).

To build a dict in DTML, try something like this:

<dtml-call "REQUEST.set('mydict',{})">

<dtml-call "mydict.update({'e':7})">

<dtml-with mydict mapping>

What would it add ? But a CSS-method or similar would be a nice addition.

Or even a general TEXT-method, with Content-type: as an attribute, so I don't 
need to write <dtml-call "RESPONSE.setheader('Content-type'. .... for all 
non-html methods

Why ? As has been revealed in several discussions before, it would be very 
limiting for DTML to force compliance to XML (dtml tags inside html tags, etc)

Making it only superficially similar would just confuse people.

If you could integrate it nicely with other parts of zope it would be a
welcome 
addition. But I doubt it would be easy, but if you can come up with a nice 
implementation, I'm sure it would be accepted in contrib.

IMHO this would be a very bad idea, because not all browsers are able to
use javascript. 

for example the tree tag works perfectly with lynx. This is really very
nice, because often we can't do many things with text only browsers, but
the tree tag is very powerful and lynx can use it: it's cool.

IIRC the recommended way was to use

<dtml-var REQUEST>

or perhaps

<pre><dtml-var REQUEST></pre>


It was further recommended to make a method called DEBUG in your root 
folder containing the above and set permissions so that only managers 
could use it.

You may want to check out the Zope-Mozilla initiative (and the related
Model/View discussion), which does something like this. It's on
http://www.zope.org/Resources/Mozilla. As this is Open Source,
contributions are more than welcome.

Another tree difficulty:

I have a tree widget in a page.
When branches are expanded or collapsed the
view you get in the browser moves.

Now I know this is somewhat unavoidable but
can anyone think of a way to limit the effect
for example some way of making the text above
the newly-expanded bit stay still and just
re-rendering that below instead of shifting
everything around?

I am using Interbase 5.6 with ODBC.  It sucks. 2-3 x a week the ODBC
connection gets lost, and the Zope ODBC adapter refuses to reconnect.  

It usually happens after I enter the management screens as well.

I have to shut Zserver down, and restart it.   I think the problem must
be the ODBC driver supplied by Interbase Corp.

I'll probably shift it over to MS Sqlserver as people don't seem to
report problems there.

[ preventing acquisition within a tree-tag ]

After going through the archives my third (and hopefully better tested)
trial with this :-)

In your Extensions directory create an external python method with this
code:

def prev_acqu(self, prop):
    if self.__dict__.has_key(prop):
       return getattr(self,prop)
    else:
       return ''

add it with the id prev_acqu (or anything else you like better) to a
folder in the acquisition path.

In your tree code do:

   <dtml-var "prev_acqu('rubbish')">

If you choose a different id, of course you have to take it here, too.

Forget it, its a mad idea.  I was dreaming up some
mad-brained scheme using targets (so eg each
expansion could ensure that the very top of the
page was visible in the browser) but its crazy.
I need a weekend.

That is not "locked up" -- that is the normal "blocked waiting for requests"
state that you see whenever you start Zope with the "-D" flag.

Because the FTP server code is in Python, the chances of this 
being a real classic "buffer overflow" (of the sort that can 
start to overwrite unintended memory) is slim (I expect that 
the worst you could do is send something so long that it consumes
all available memory and causes Python to raise a MemoryError).

We should look into the handling of those commands though. I don't
manage the FTP code so I don't have enough deep Zen to know what 
the "correct" behavior is, but it seems that if it's giving a 
false positive then something is probably not being handled 
totally correctly. Can you make an post in the Collector about 
this so that it doesn't get lost in the flow of the list?

Thanks!

You might also look at TimeStamp_yad() (line 117 of the same file in 2.1.4)::

  static double
  TimeStamp_yad(int y)
  {
    double d, s;
  
    d=(y-1)*365;
    if (y > 0) 
      {
          s=1.0;
          y=y-1;
      }
    else
      {
        s=-1.0;
        y = -y;
      }
    return d+s*(y/4-y/100+(y+300)/400);
  }

I _think_ the last line should be::

    return d+s*((y/4)-(y/100)+(y/400));

"every fourth year, except century years, except every fourth century".  Perhaps
the original was "working" to compensate the base 1900 vs. base 0?

Weirdness...

I've almost got mod_pcgi2 setup to serve my entire site fronted by Apache
but I've run into one final snag.

When I access the home page of the site I notice that the BASE HREF
returned by Zope is saying its http://XXX/index.html/

Apparently Apache is appending the Index name for the folder?

I tried Options -Indexes but this didn't solve it.

Anyone have a valid configuration for this situation that I can take a
look at?

Thanks,

It's also worth mentioning that when you do this to call DTML Methods and
External Methods some things automatically get passed in. When you use the
expression form, these things are not passed in. The most important thing is
that the namespace is passed along to DTML Methods and this() and REQUEST
are passed along to external methods. I haven't looked at the python source
to know exactly what is passed in these cases, but you generally will get
what you want if you do this for DTML Methods:

<dtml-var "myMethod(_.None, _)">

and this for external/python methods:
<dtml-var "myMethod(this(), REQUEST)">

   This has nothing with mod_pcgi2 or Apache - it is Zope who adds BASE.
May be you can eliminate it with SiteAccess. It seems you are trying to do
virtual hosting with Apache, and Zope is not capable yet of virtual
hosting, but SiteAccess is one method to helps.

Subject: [Zope] Trouble with dtml-in
Message-ID: <38BFDB65.3AFA8796@lunateks.com>

I'm having trouble with using dtml-in in batch mode.

A syntax like this:

<dtml-in objectlist size=1 start=qs>
  <dtml-var sequence-item>
</dtml-in>

Works properly when qs=1 or qs=0 (treated as 1). Anything more than 1
causes it to ignore the "size=1" setting and loop through all the
elements in the list. The "next" and "previous" parameters exhibit this
problem too.

I can't understand what I'm doing wrong. I'm using the exact code as in
the DTML reference (except for the size of 1).

I upgraded from Zope-2.1.1 to 2.1.4 to see if this problem had been
fixed, but no luck yet.

The only way I can find to get around this is to remove the size=1
parameter and use a <dtml-if "_['sequence-index']-1==qs"> to make the
batch work.

A colleague insightfully commented that while Dynamo has a high bullshit
factor, this is the reason it sells.

Take a look at this screen shot:

http://www.atg.com/news/images/screen-shots/systemconsole.gif

Dynamo is an expensive, closed product with a promotional web site that
smells like a million-dollar penthouse office space, replete with glass
walls and postmodern sculptures. It smells a bit funky, and the people
are possibly evil, but the product is of high quality, and it sells. And
because it sells, many people use it, and because so many people use it,
skilled developers exist in large numbers. Unfortunately, I can't say
the same of Zope.

Speaking of which, SNMP support for Zope would have been nice. Then we
could import the numbers needed to build monitors like the one featured
in the screen shot.

Sorry; I wrote sloppily and shouldn't have said "exported".  This is
the .tgz file produced when you make a distribution of a ZClass-based
product.  For that, you do need to restart Zope -- but the new Product
never shows up.  I haven't yet dug into Zope to see if this feature is
broken, or if something else is going on.

Subject: [Zope] Finding matches between two lists
Message-ID: <3.0.6.32.20000303091400.009538f0@pop.dnvr.uswest.net>

Hey all!

	This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

	---------

	The layout:

	Most of my code is in a Python Product, but there is still a bunch of dtml
used.

	I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

	Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

	---------

	The DTML attempt:

	I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

	<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">
                   <A href="<dtml-var site_url>/<dtml-var id>"><dtml-var
sequence-item></a>, 
                 <dtml-else><dtml-var sequence-item>, 
                 </dtml-if>
              </dtml-in>
            </dtml-if>
          </dtml-in>
        </dtml-with>
    </dtml-if eventnames>


	---------

	The Python attempt:

	So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

    def list_dj_list(self, namelist):
        """ should return a list of names & IDs from a list of names
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rnames = []
        for i in range(len(namelist)):
            rnamelist = rlist
            rname = filter(lambda x,p=self,s=namelist[i] : p.data[x].name
== s, rnamelist)
            if len(rnames) == 0:
                rnames.append('None')
            elif len(rnames) == 1:
                rnames.append(rname)
            else:
                rnames.append('multiples')

        return rnames

	---------

	The question:

	How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

	Thanks for any help!

If I understand you properly, then I think you'll find the Squishdot product
perfect for experimenting with a "real" zope site. Squishdot is a product
that emulates the functionality of Slashdot. You can read about Squishdot
and download it at

http://www.zope.org/Members/butchland/Squishdot

Make sure you install the TinyTable product too for the full tour.

Funny, I had never heard of Dynamo before you mentioned it here. 
Fortunately, I can't say the same of Zope ;)   I think you underestimate
the actual numbers of people and sites that use Zope.  I also think that
you are creating FUD so that you can get a feature you want to see 
implemented by the folks at DC.  Truly bad taste.

Please no.  There is NO reason to pollute Zope with something as insecure
as SNMP.

Subject: [Zope] 'helper' classes in External Methods
Message-ID: <v04220803b4e59f28a438@[128.240.198.13]>

Can someone give me a pointer to what these helper classes actually 
do? Can I use them to setup lists and dictionaries that will be used 
over the lifetime of the Zope server?

This is an example from an external method that Pavlos posted a while back.

class MCQ:
         ''' helper class for MCQ system'''
         def __init__(self, score):
                 ''' constructor'''
                 self.score = 0
                 self.total_score = 0

What I would like to do is load up a template_lookups dictionary with 
quite a few entries;

for template_id in self.Actors.RENDER.objectIds():
         renderer = eval("self.Actors.RENDER.%s" % template_id)
         template_lookups[template_id] = renderer

Thing is, I need access to the ZODB in one of my methods later in the 
module and so the above code doesn't work (too many 'selfs'!).

Anyone got any ideas?

Well, I am doing Virtual Hosting via Apache, but I'm only running one site
per instance of Zope.

Isn't this possible with pure mod_pcgi2?

Note that the servers listed as runinng Zope on Netcraft, are those that run
straight ZServer. Those sites that run Zope behind Apache, IIS, Zeus, or any
other webserver, will be listed under those webservers. So, a small
percentage of the number of Apache sites on the web, runs Zope.

From my personal expirience, I find that a lot more people run Zope behind
Apache, instead of pure ZServer. So, the number of Zope sites is a
significant factor higher than the 300 listed by Netcraft.

For an example, go to:

  http://www.netcraft.com/whats/?host=www.zope.org

You'll see that it is listed as running Apache (which it is).

Subject: [Zope] Finding matches between two lists
References: <3.0.6.32.20000303091400.009538f0@pop.dnvr.uswest.net>
Message-ID: <38BFF7BB.8EA2DA2B@vt.edu>

Hi, ed.

I think I am a bit dense today, so could not quite understand completely
what you are doing, but

If you want to find matches between lists, there is a cool thing in
Python that can possibly help you.  

Let's say I have two lists, list1 and list2, and I want to know what in
list1 is in list2, which is I think what you are going for.

list1 = ['n', 'b', 'r']
list2 = ['f', 'd', 'b']

def intersect(lista, listb):

    tmp = []
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp.append(anitem) #if there, append to the temp list
    return tmp                 #return the temp list

print intersect(list1, list2)  #should be ['b']

If I want no dupes, (if 'b' is in list1 twice, it will be returned
twice) I probably would use a dictionary instead of a list and return
the keys, e.g, 

def intersectnodupes(lista, listb):
    tmp = {}
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp[anitem] = 1    #if there, throw it into the doct
    tmp1 = tmp.keys()          #get the keys (arbitrary order, alas!)
    tmp1.sort()                #the keys are in arbitrary order no
longer
    return tmp1                #return the unduplicated list

In DTML, you can use the 'if athing in alist' thing too:

<dtml-call "REQUEST.set('list1', ['n', 'b', 'r'])"> <!-- or use your own
lists -->
<dtml-call "REQUEST.set('list2', ['f', 'd', 'b'])">

<dtml-in list1>
<dtml-if "_['sequence-item'] in list2">
<dtml-var sequence-item> <!-- do something with the things in list1 that
are in list2 --> 
</dtml-if>
</dtml-in>

Message-ID: <3.0.6.32.20000303184315.0093e620@poirot>

Hi,

I'm once again trying to get further in my test products.

* I've created a catalogAware ZClass, called KBItem
* KBItem contains an external method with id manage_afterAdd

Now, I can add KBItem instances in Zope without problems, BUT!

when having a ZCatalog inside a folder with the id Catalog and then try to
create a KBItem instance, I get following error (where testje is the id of
the KBItem I try to create) :

Zope has encountered an error while publishing this resource. 

           Error Type: ValueError
           Error Value: Uncatalog of absent id 'TEST_Folder/testje'

Help! I don't know what I'm doing wrong or what is happening!
What does it mean and what can I do?

Thanks in advance,

Tom.

if you have 2 queries one of which returns tuples containing events and usernames,

Subject: [Zope] Finding matches between two lists


Hey all!

This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

---------

The layout:

Most of my code is in a Python Product, but there is still a bunch of dtml
used.

I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

---------

The DTML attempt:

I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">
                   <A href="<dtml-var site_url>/<dtml-var id>"><dtml-var
sequence-item></a>, 
                 <dtml-else><dtml-var sequence-item>, 
                 </dtml-if>
              </dtml-in>
            </dtml-if>
          </dtml-in>
        </dtml-with>
    </dtml-if eventnames>


---------

The Python attempt:

So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

    def list_dj_list(self, namelist):
        """ should return a list of names & IDs from a list of names
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rnames = []
        for i in range(len(namelist)):
            rnamelist = rlist
            rname = filter(lambda x,p=self,s=namelist[i] : p.data[x].name
== s, rnamelist)
            if len(rnames) == 0:
                rnames.append('None')
            elif len(rnames) == 1:
                rnames.append(rname)
            else:
                rnames.append('multiples')

        return rnames

---------

The question:

How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

Thanks for any help!

Hi Tom,

This might be because the CatalogAware class uses the manage_afterAdd hook
itself (CatalogAwareness.py).

In _your_ manage_afterAdd(self, item, container), try this (untested):

def manage_afterAdd(self, item, container):
      # do whatever want to
      CatalogAware.manage_afterAdd(self, item, container)

Hope this works.

Great idea!

However, no I get this error :

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: CatalogAware

Do I've to place somewhere an import of the CatalogAwareness library?
I'm afraid my knowledge of Python is to low to solve this correctly. Any
ideas?

Tom.

Hi,

I installed Zope 2.1.4 on my RedHat 6.1. I wanted to change the password given
by the installer. I tried : 
python zpasswd.py -p=mynewpassword access

Everything seems ok. I have new file called access which looks like the older
one except for the 'password' part.

1 - Do I need to restart zope in order to have the new password be effective.

2 - Even if I restart zope, i cannot use my new password. However if i replace
the new file called access by the old one, i can acces to the zope management
screen.

What have I done wrong?

Message-ID: <3BA3A8B61E4ED211ABB900A0C9615FE639C822@sev-mail.gtri.gatech.edu>

Okay, I'm new to Zope (3 days), but I was having such success with some
simple things that I thought that I could handle something tricky - I've
been working at it for a day now.

What I would like to do is present two selections (Division and Team) that
are populated from an ODBC connection.  I can do the population fine,
normally; but the trick is that I'd like to have the Team selection
dependent upon the Division selection (on the same web page).  I realized
that I couldn't do this on a simge form (or can I?), so I've assigned the
two selections to two forms.  I'm putting the two forms on the same page for
aesthetic (stubborness?) reasons.  Here's the code for the first form:

<form action="index_html" method="get"> Division:
  <select name="division" width=30 value="">
    <dtml-in sqlShowDivisions size=50 start=query_start>
      <option> <dtml-var age_group>
    </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>


This part works fine.  When I submit the form, the same page is regenerated
(with the 'division' parameter passed in).
One of my many failed attempts with the second form (which is also in
'index_html') is as follows:

<form action="TeamSchedule" method="get">
  <dtml-var division missing="Undefined"> Team:
  <select name="team" width=30 value="">
     <dtml-in sqlTeamsInDivision size=50 start=query_start>
        <option><dtml-var name>
     </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>

my sqlTeamsInDivision has 'division' as its only parameter.

When the user first enters the document, he gets an KeyError on 'division'.
I understand why this is so (the division parameter doesn't exist yet), but
I can't seem to work around it .

I tried changing the sql parameter to divisionname and changing the
<dtml-in> tag to:

<dtml-in expr="sqlTeamsInDivision(divisionname='<dtml-var division
missing>')" size=50 start=query_start>

and the error goes away, but the returned list is just blanks.  How should I
be handling this?

Also, when this form is submitted, it calls TeamSchedule with the 'team'
parameter, but I need to also pass the 'division' parameter.  How do I do
this?

Thanks in advance.

Subject: [Zope] Installation trouble on Solaris 2.6
Message-ID: <NDBBLONFDKEIFDBOFGJMCENCCCAA.ztf@one.com>

Hi all,

I'm trying to install Zope from source on a Solaris 2.6 system,
and I'm running into problems.

When I try "./start", I get the following error:

$ ./start
$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

/opt2/local/zope/Zope-2.1.4-src/lib/python/ExtensionClass.so: symbol
PyImport_ImportModule: referenced symbol not found

I am new to Python, so it's less than obvious to me what is going
on here.  It looks like the ExtensionClass module is failing to
import, but I have no idea how to go about fixing this.

[Yes, I know about the precompiled Solaris 2.6 binary.  However,
I eventually will need to get this running on a Solaris 2.5.1 system.
Also, as far as I can tell, the binary release is not set up for
Apache integration, which is something I also need to do.]


Thanks in advance,

I think it is not a good idea to define classes in external methods. It is
better to define them somewhere in Shared (see the directory DC under
lib/python/Shared for example) and import them in your external method. 

import Shared.Tony.helper

 They can be very handy especially since python is way more elegant and
easy for complex logic in relation to DTML.

Not sure. need some more info. Did you try to use getattr to get to

tmp=self.Actors.RENDER
renderer=getattr(tmp,template_id)

What kind of object is template_id?

People did report this bug elsewhere on the list. Apparently we're waiting
until monday when Jim Fulton can take a look at this. They're pretty sure
it's just a display problem and not something wrong with the object database,
but they want to make sure and check with Jim.

Message-ID: <NDBBLGMIGNLPGELLJNNIGENGCCAA.tneff@bigfoot.com>

If you are sure that you can get along without the BASE HREF in a virtually
hosted (or other) Zope page, there is a way to fool the ZPublisher so it
doesn't include the obnoxious tag.  Just put

	<base dummy=dummy>

near the top of your method.  This turns out to be enough to fool the fairly
droidal scanning code into thinking that no additional BASE tag is needed.
Since it's an unknown attribute it should be a total no-op in browsers.  Of
course they could write a smarter parser in a future release so caveat
Zopor, but it works for now.  I wish they hadn't relied on that tag to begin
with.

Okay, never mind.  I figured it out.  I needed to use:

 expr="REQUEST.has_key('division')

to determine if the 'division' has been defined.

Also, the passing of multiple variables was obvious - just define a hidden
input field.

Thanks, anyway.

Message-ID: <007c01bf8553$1d6fa8e0$7b5addc7@laptop>

KM|Net News is a Zope through-the-web Product that allows you to post
news-style articles on your site. 1.1 is easier to install (because it
creates its own Catalog and does not have any external methods) and now
incorporates linking to external sites for more weblog-style publishing.
(KMNN is still different from Squishdot in that there are no discussions
attached to the articles and has different features for placement of the
articles within the article listings). You can see KMNN 1.1 in action at
http://www.byproducts.com

KMNN 1.1 also includes a new "contrib" method for trusted people to
contribute articles without review.

*** KMNN 1.1 requires PythonMethods. ***

You can get KMNN here:
http://www.zope.org/Members/tazzzzz/kmnn

If you're upgrading from an earlier KMNN, you may want to use the "Restore
Defaults" tab to "Rebuild Catalog" and restore "incoming.html". The new
incoming.html adds the fields for external articles.

This will probably be the last major revision of KMNN before the PTK.

Subject: [Zope] Logging users in Zope 2.x (second try)
Message-ID: <38C036C6.2300C61C@tm.ee>

How should I configure logging to get usernames into Z2.log

I first hoped to get it from Apache's access_log, but it saves 
username only when doing user authentication itself.

Then I thought that Zope at least would log it and migrated the 
site to Zope 2.1.3 to get logging support. 

Unfortunately it does still not log usernames and I have not 
found the place where I could turn it on.

Also the format is buggy:

Apache access_log:

193.40.215.135 - - [11/Feb/2000:08:29:55 +0200] "GET / HTTP/1.1" 200 2673

Zope Z2.log

127.0.0.1- - [11/Feb/2000:19:04:46 +0300] "GET /misc_/OFSP/dtmlmethod.gif" 200
1000

the bug being the missing space after the IP address.

what I was hoping for would have looked like:

127.0.0.1 - superuser [11/Feb/2000:19:04:46 +0300] "GET /manage" 200 1000

It looks like your dynamic linker cannot find your python libraries. 
There is an environment variable that you must set so that the linker
can find any libraries needed by shared library modules like
ExtensionClass.so.  I believe the env variable beings with LD_.  Do an
'env' (in bash at least) and look for something like that.  I never
remeber it cuz in Linux you just edit a file.

The binary will work fine with PCGI (Apache integration).  Whether it
runs on 2.5.x I don't know.

Hi Tres, Hi Jack,

Thanks for the infos/repost.
Is there no way to control UW IMAP to look for a specific folder in each
user's home dir for the INBOX root? Something like the way
http://host/~username/ mapping works in apache?

If not, then I'll add this instruction to the upcoming FAQ for
worldpilot, since this is the no.1 question up to now. (Jeeze, looks
like I'll have to install UW IMAP myself afterall, too.)

Cheers,
Ryan

In Amos Latteier's "creating XML Applications With Zope" at
http://www.xml.com/pub/1999/12/zope/index.html


There is an example that uses a Zcatalog.

He says to enter this into the expr field of the "Find Items to Zcatalog":

getNodeName()=='entry'


and click find.

When I do this with my own version, or even his version 
Zope gets this error:

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: Eval


it has to do with that entry in expr.

Is that a typo?

Sorry, coming in late here. The Env variable you need is LD_LIBRARY_PATH. Mine
is set to
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib:/usr/local/lib/mys
ql

(I know this 'cos I did a new Zope install the other day on an account that
only had 
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib
I started the Zope server under that account and found a broken MySQL product,
with an error message saying it couldn't load libmysqlclient.so.6. I had cold
chills going down my back for a looong few minutes....shudder)

Subject: [Zope] Assorted Zope problems
Message-ID: <20000303164457.A1221@velocity>

Hello-

I've been trying to get our existing Zope server (previously with ZServer
handling http) under Apache.  Here are some problems I ran into:

1. My biggest problem was that Zope uses the SCRIPT_NAME environment
   variable to construct it's notion of the base URI.  Unfortunately,
   SCRIPT_NAME gives the actual script name, not the URI.  So if you
   do a ScriptAlias, or any rewriting inside Apache, this isn't necessarily
   valid.

   An adequate solution seems to be to change
   PYTHONHOME/lib/python/ZPublisher/HTTPRequest.py line 211, to use
   DOCUMENT_URI instead of SCRIPT_NAME.

2. I couldn't get Apache with FastCGI and Zope working reliably.  On about
   1% of requests, garbage would be returned, resulting in random broken
   images or pages full of gibberish.  This is with the Oct 06 snapshot of
   FastCGI, compiled into Apache-1.3.12.

Anyone else seen anything like this?

Ed

Just curious, what does the result of a LIST with "~/Mail" look like on
UW IMAP?
What is the top node labeled as? 
I guess I could add a parameter to control the behaviour of the LIST
call.

"1%?  You were _lucky_!" (in my best Yorkshire accent).  I was getting
a much higher rate of errors (admittedly, I was only using the management
screen at the time as I was just starting out with Zope), but I ended up
switching to mod_pcgi2 to cure these problems.  The problem has been
mentioned before on the mailing list, but I'm not sure if a solution has
been found.

Platform is (for data point purposes): RedHat 6.1, Apache 1.3.9, Zope
2.1.4 and fastcgi Oct06 snapshot.

I want to write an object that can be traversed by ZPublisher.  The
goal is so I can write URLs like thingyForwarder/45/display, to get an
object corresponding to thingy #45, and call its display() method.

What's the Zope Zen way of doing this?  Implement an __of__ method for
acquisition?  Implement a __bobo_traverse__ method?  Make
thingyForwarder a Folderish object and implement all the folder
methods?

Subject: [Zope] Client-side Zope
Message-ID: <002501bf856e$7aee5640$770da8c0@bbs>

Continue to moving more job to the client, There will be more for Zope to
perform:

1. There will be necessary to generate various section-specific temporary
objects for CSS, DTD and Scripting files, framed or embeded html.

2. There will be necessary to support java or javascript access of zope in
the client.

In the first requirement, I would like to suggest an machenism to create an
section specific temporary object (which zope create the unique name and
substitute it) which dtml is able to write to it. The new object can be just
a new dtml-document. As in the following

<dtml-object dtdobject>
<dtml-object scriptobject>
<dtml-object cssobject>
<script lang="javascript" src="<dtml-var scriptobject>">
....

<dtml-write target=scriptobject>
function <dtml-var uniquevalidfunctionname>(){
   ....
}
</dtml-write>

I don't known about the solution of the second request.

In the long run, zope might encourage separate of control and data. The
current opening all tags in one dtml-method and closing them in another is
very dangerous if the control get complicated. I would like to suggest DC
consider a xslt like syntax which can also be used in server side xml to
html conversion if the client do not support it.

If zope is going seriously to the international market and xml, then unicode
is important in the core level.

I think __bobo_traverse__ will do what you want. You can look at the local file
system code in LocalFS.py as an example.

Nope, a bug.  The fix is in CVS but failed to make it into the 2.1.4
branch.

Put this line just after the license in
lib/python/Products/ZCatalog/ZCatalog.py

from DocumentTemplate.DT_Util import Eval, expr_globals

and it will work.

Take yer pick.

ZPublisher will try the following methods to traverse an object, in this
order:

__bobo_traverse__(request, name)

  Request is, suprise, the REQUEST object, and 'name' is the path
element ZPublisher is trying to traverse to.

getattr

  ZPublisher will try and get the subobject by 'name' with getattr.  If
this fails with an Attribute error then...

getitem

  ZPublisher will try to get the subobject by 'name' with getitem.  If
this fails, you get a 404.

One subtlety to be aware of is that __getitem__ seems to be called *after*
acquisition is given a crack for reasons that elude me. Since I've never been
able to get an explanation of how to use __getattr__ without blowing up the
acquisition machinery, this makes __bobo_traverse__ the only foolproof way that
I know of for hooking traversal. Someone please correct me if I am wrong.

The reason you have not heard of Dynamo is that Dynamo isn't being
hyped; Zope is.

There are other, non-Zope solutions out there, some of them quite solid.
I like to keep an open mind, and so should you. There are, indeed, quite
a number of people who have heard of Dynamo but never heard of Zope.

While my statistical data is entirely non-existent, I'll wager that
Dynamo-awareness exceeds Zope-awareness by a factor of at least two. ;-)
This isn't necessarily something to get upset about, and anyway I
believe, and hope, that the difference is shrinking.

Just a bit of background since you're accusing me of FUD.

Dynamo drives many of the web's most popular sites, and is in direct
competition with Zope, sharing the application server space with
contenders such as SilverStream, Sybase, Vignette, Jade, and many
others. Along with Vignette, Dynamo is one of the most successfully and
widely employed app servers solutions in existence. Whether this is a
good or a bad thing I'll leave for you to decide; I don't like Dynamo,
but I acknowledge its technical edge on Zope (and other solutions) in
several areas, such as clustering, reporting, personalization services,
e-commerce services, stability, and raw speed.

As an artifact of Dynamo's platform of choice -- Java -- there is
indirectly a "virtually limitless" expertise on Dynamo. If you know your
Java and your Enterprise JavaBeans, you already know Dynamo, and
stepping into your Dynamo shoes will be easy. Compare that to stepping
into Zope's multiple zens: acquisition, DTML, objects, Python. Note that
I'm not arguing against Zope here, which has a self-inflicted and
justified learning curve. However, managers will not necessarily respect
this difference in philosophy: The cost of training a person in the arts
of Zope will be measured against the cost of hiring an already-trained
Java wizzkid, and -- at least right now, today -- Zope will lose.

This situation has nothing to do with open vs. closed, either. Just like
Zope we're talking about proprietary (as opposed to standarized -- DTML
may be open, but it's still proprietary) technology. The fact that Java
is more widely established, and evolving faster, than Python is
unfortunate and outright infuriating, but right now that's how the cards
are dealt.

Dynamo also costs a lot of money. For small businesses, it costs too
much. A heavy-duty support contract with Digital Creations also costs a
lot of money, but you have a choice. On top of that, Dynamo is
open-ended but not open -- there is no source distribution.

My point? Zope already has a foothold in the small-time web site segment
of the market. However, big people wield big swords, and Zope, despite
its many powerful features, is not big enough for truly big things.

This is a two-part problem. The first part is that Zope's bullshit
factor is too low; it's not flashy enough to convince a senior manager
that Zope has enough clout for their business. It's a purely aesthetical
apprecation of Zope's poor-man, open-source philosophy, and the fact
that Zope does not offer a comprehensive monitoring system with a ticker
bar providing useless but impressive information does not fare well with
those who like to be bullshitted. We tech people know better, we know a
shiny surface tells us nothing about the engine underneath, but we tech
people are not holding the crucial component -- those big brown bags of
money.

Now, the second part of the problem is that underneath Zope's lacklustre
but entirely deceptive surface lies a powerful engine with scalability
problems. So far the only way to scale properly with Zope is a
combination of a load-balancing clustering system (eg., TurboLinux'
TurboCluster Server, which I can personally vouch for -- brilliant stuff
-- or Linux Virtual Server) with Digital Creations' ZEO, of which I've
only read about. There are Zope sites out there that are suffering
scalability problems (I won't mention specifics, other than that the
project I'm involved in is one of them). The problem is real, and
intrinsically related to Python. I wish I fix Python rather than sit
still and bitch about it; I periodically express my dissatisfaction with
Python's lack of performance, and I have certain ideas as to how to
improve it, but a research project like this would take time, of which I
can currently allot none. So instead I just bitch. ;-)

Finally, as for DTML being proprietary, Zope desperately needs native
support for XSL/XSLT as an alternative transformation language. I think
it was Michel who spoke vaguely of this being considered incorporated
into a future version of Zope. (At one point I planned doing an XSL
product, but I have not yet had a project to fund it with. So I'm not
just bitching here.) We also need better in-line scripting capabilities
than currently offered with External Methods and PythonMethods. This to
fight the creeping and ever-expanding notion that Java (replacing
Smalltalk) is the chosen, possibly even pre-destined, language for app
servers and middleware. Try to find an OODBMS, RDBMS, or application
server nowadays that does not use, or plan to use, Java as its
fundamental extension mechanism. I can think of a few, but they're few.
If you want to talk about FUD, you've got it right there.

Anyway, just my two cents.

Then please offer us an alternative, open, standarized interface to
monitoring data. The fact that SNMP in itself is insecure has little, if
anything, to do with whether Zope should be "polluted" with such
support.

An alternate route might be to have Zope export necessary variables
through a well-defined XML DTD, and then provide the necessary tools to
convert this XML output to SNMP, although supporting SNMP traps this way
would be difficult.

Perhaps supporting Performance Co-Pilot
(http://oss.sgi.com/projects/pcp/) would suit you better. Unfortunately,
PCP is probably not -- at least not now -- portable to Windows NT. In
fact, I'm not sure whether PCP will exist outside IRIX and Linux for
some time yet.

As far as pollution goes, assuming Zope exports the appropriate data --
in whatever form -- then support for performance/monitoring/management
APIs such as SNMP, PCP, WBEM, and to a lesser extent PDH, aren't
difficult to isolate into add-on products.

Thanks, Tony and Michel.  Unfortunately, LD_LIBRARY_PATH doesn't
seem to solve it, which is really puzzling.

The gory details are:

My base Zope installation is /usr/local/zope/Zope-2.1.4-src.  So,
ExtensionClass.so is in /usr/local/zope/Zope-2.1.4-src/lib/python.
My LD_LIBRARY_PATH is
/usr/local/zope/Zope-2.1.4-src/lib/python:/usr/local/lib:/usr/openwin/lib,
which ought to pick up ExtensionClass.so.

Anything else which would cause the import to fail?  I tried setting
PYTHONPATH too, in desperation, but it doesn't seem to make any difference.


Thanks,

Zach Frey


P.S.: I did try the binary distribution on Solaris 2.5.1, and can
report that it doesn't work.  Zope fails to start up with an unresolved
symbol error, so it really does require 2.6+.

If you consider separate code and data. If you think about putting
XMLDocument in real use.  This is one of the possibility:

using an xmleditor, the user can save the xmldocument to zope server as zope
automatically make all parts of the document reusable as zope object (is it
all what zope about? making a document into many small parts as each of them
be re-usable object?) This is process by zope automatically, the author do
not required to do extra works. The author can edit the document or part of
it and view the final result if the xml-editor support this.

To make this better, the author can embed dtml code in the xml document,
which make the document be active and live. You may have a system
automatically updated. Isnt it what zope designed to be?

The document inside zope can have multiple view as we can have dtml-methods
to transfer them into different view: html, xml+xsl+css, pdf, doc, etc...

If dtml syntax is not xml-complience, all of these will not happen.

A deeper change is to make dtml syntax more xsl like. I.e., make it block
oriented. So, the author is forced to code in good manner, instead of the
opening and closing tags were spearated into many places which I think is
very bad for maintenance.

I believe the problem is with ZServer/FCGIServer.py.  If you pull the latest

FCGIServer.py (1.5.4.1 at the time), the problem went away completely.

Actually, what I am working on is abstracting that out. :)

What I _want_ to do, is to allow you to customize how you store the
dynamic data (like hits, clicks, remaing hits/click, etc.); whether it
be in an RDMS, Zope, File, whatever. I think I've got a pretty good

I was thinking of an XML-RPC cronscript, though that wouldn't work on
windows boxes(?). Perhaps the recent Scheduler product will mature
enough, soon enough.

Subject: [Zope] PostgreSQL money weird problem
Message-ID: <38C06A0A.1DD2F6BF@uol.com.br>

Hi,

I'm with a weird problem with a report from a SQL database. I have a
field of type 'money', and every time I use it in a SELECT query, it
returns 0.00, doesn't matter the actual value of the field (in the
example bellow - the 'test' of the query -, the field Valor is of type
'money'):

 Id | Idcliente | Data       | Valor
  1 | 11        | 03-03-2000 | 0.0
  2 | 11        | 03-03-2000 | 0.0
  3 | 11        | 03-03-2000 | 0.0

SQL used:

select *
from compras
where idcliente=11

Running the same query on the interactive client, gives the value of
money:

credito=> select * from compras where idcliente=11;
id|idcliente|      data|valor   
--+---------+----------+--------
 1|       11|03-03-2000|R$50,00 
 2|       11|03-03-2000|R$150,00
 3|       11|03-03-2000|R$15,00 
(3 rows)

I'm using Zope 2.1.2, ZPyGreSQLDA, and PostgreSQL 6.4.2, running in a
Conectiva Linux 4.0 (kernel version is 2.2.5).

The definition of the class compras is:

Table    = compras

Hi Ryan,

I thought I'd jump in on this since it gives me a good reason to learn a little
more about how IMAP works. ;-)

I logged in via telnet to my test system and determined (with some help
from the IMAP4 RFC) that the command being executed is 

LIST "" *

Since the UW IMAP server logs the user into their system account I can only
assume that this drops them into their home directory. If I execute the
requested command it will return nothing unless a Mail directory exists in the
users subdirectory. (I have one user setup this way from earlier tests and one
without the directory.) 

Executing the command LIST Mail * returns the same as LIST ~/Mail * for the
user with a Mail directory. 

I will attempt to do some checking on the functionality of the .imaprc file that
is sort of documented and see if this can be used to work past the problem.

Subject: [Zope] FYI: large files & linux.
Message-ID: <38C0AF01.C9887838@imeme.net>

Zopistas,

I was trying to get large file support on linux.  I succeeded, but only
partially.  Steps:

1. Download and install a kernel greater than 2.3.27. 
   It has the large file patch built in.

2. Reformat ext2 partition with 4k blocks:  
   mke2fs /dev/hdaX --block-size 4096
   the maximum filesize for ext2 depends 
   on the blocksize: with 4k blocks, it's 1TB.

3. Use Glibc 2.1.13-5 from debian potato.  
   unknown whether 2.1.12 from the gnu site is sufficient.

4. compile python 1.5.2 like so:
   CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" OPT="-O2 $CFLAGS"
\
 ./configure --with-threads

5. Now you can make files up to 4096 MB in size.  Why no bigger?
   I have no idea.  For me, at least, it means 1/2 as many zopes.

Optional step:

Wait.  In a few short months Linux should handle large files natively.

Ok, so you can't use the Zope distn that has a precompiled Python bundled (it
seems).

Try setting LD_LIBRARY_PATH as above and recompiling your Python source
distribution.

I know I had a real pain getting Zope-src distns running under Solaris (and
then found that our big expensive Sun Iron was half the speed - in pystones -
of my iMac! ...grrr) - but it can be done.

I would prefer this scheme too. You are breaking up a document into constituent
'blocks' in a different way than it is done presently.
I suspect you may get not only this but more in the future. There have been
similar thoughts going on in people's minds:

You'll have to call your DTML Method in a special way. When caling a DTML
object with <dtml-var name=DTMLMethodOrObject> this is automatically taken
care of. but when using it in the above way, you have to do this by hand:

  <dtml-in "creditCardSelections(_, _.None, *other arguments*)">

You now pass in the namespace as well, so your DTML knows how to access
other Zope Objects. This _will_ change in the future, BTW, this will be
automated for various reasons. You then won't have to think about all this
anymore.

Have alook at the following How-To, and espcecially the list referrenced at
the bottom of it:

They will introduce you to the more advanced ideas of DTML scripting.

I've just moved from qlcomm.com to the current location. Your DNS server
must still be using the cached entry. Should be fine in a little while.
You can mail me at jace@radiolink.net until then (the address I used to
subscribe to the list).

Here is what I use:


<dtml-var standard_html_header>

<dtml-with aq_parent>

<dtml-in "objectItems(['DTML Method'])" previous size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var previous-sequence-start-number>">
(Previous <dtml-var previous-sequence-size> results)</a>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" size=1 start=page>
     Document id: <dtml-var id>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" next size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var next-sequence-start-number>">
(Next  results)
</a>
</dtml-in>

</dtml-with>

<dtml-var standard_html_footer>

-----------
This doesn't work. When page=1, it's fine. When page >=1, dtml-in loops
all the way from "page" to the end of the list. I don't know why it's
doing that. The "dtml-in next" loop also does the same thing.

To explain the setup: I have a ZClass called "Article" based on
ObjectManager and set to accept only DTML Methods and Images. The above
code is in a DTML Method called "index_html" placed in the ArticleClass
(not when being implemented). I had the same annoying problem when
working with the results from an SQL query instead of objectItems. My
workaround then was to leave out the "size" parameter and instead use
dtml-if to compare sequence-index with page. It's ugly but usable when
there are only 4 or 5 pages.

I filed this in as a bug about an hour ago. Hope it gets resolved
quickly.

I've never used the DC Shared folder before. I've had a look in there as you
suggest and found some interesting things there. Time to read the docs on this
aspect I think...

Definitely. I'm now using the XXX PythonMethods that Evan Simpson contributed
and it's *definitely* helping to speed up development time.

Sorry, I should be more specific. The above code is in a method - def
supercascade(self, tag_id): which is called from Zope with a query_string,
tag_id=231441.

That code works, but I need to load up the renderers everytime supercascade is
called. I'm looking at the helper classes to see if I can't load up the
template_lookups array once. Having said that, supercascade isn't called
anywhere near the number of times that make_html (the method that generates
the HTML for display) is, so it's possible that I'm flogging a dead horse
here.

> tmp=self.Actors.RENDER
> renderer=getattr(tmp,template_id)
> 
> What kind of object is template_id?

It's a DTML document of the form (this example has id = lecture_info);
---
<hr>
<p class="<dtml-var class>"><dtml-var content null="&nbsp;"></p>
---

make_html then has a snippet in it so;
try:
    template_str = template_lookups[theclass]
    template = DocumentTemplate.HTML(template_str)
    theresult = template(self, content=content, src=src, thetag=thetag,
level=level, the
class=theclass, header=header)
    return "<!-- theclass [%s] thetag [%s]  -->" % (theclass, thetag)  +
theresult
except:
    pass

which will then render the HTML appropriately. The *really* neat thing is when
you have more complex DTML in the template that has ZSQL calls etc. 

It works well, but I want to speed it up a bit - it can take up to 6 seconds
to render a 100k document, and if I've understood my Zope architecture
correctly, thats one thread used up (and I'm only using the default thread
count - I think it's six) until the request has finished. I'm sure that
previous messages on the list have implied that it's not worth changing the
number of threads to something like 32-64, but I'm not sure.

That's my main problem, people are hitting the site and generating lots of
requests that are in the >1 second range. With our Apache servers, we just
spawn ludicrous numbers of httpd processes and don't worry about it. Zope is a
different kettle of fish and I need to think differently about it.

Many thanks for your help Pavlos, I feel things are a quite a bit clearer now.

Of course.  Some people suspected a "user error" at first, though. 
:-)

Anyway, I wasn't reporting a bug anymore,  I found the probable 
cause in the TimeStamp module, in the meantime, and reported 
that findings, and a way to fix it, here.

Lets hope for the best. :-)

PS: people have asked my for the modified TimeStamp module in 
(TimeStamp.pyd on my NT system) in private mail, but I'd prefer to 
have them wait for an "official" fix.  Poking around in the object data 
base source isn't something to take lightly.

   How many items are there in objectItems? May be you need orphan=0?

Subject: [Zope] Worldpilot/Python help
Message-ID: <003701bf85e2$693d6e80$6400a8c0@nc.rr.com>

I was very comfortable in my cozy PHP/MySQL world, until I saw Worldpilot.
I HAD to finally break down and
install Zope so I could have this.  Needless to say, my python/Zope skills
are a little lacking at this point.  I could
use some help.

Everything is installed and working great, except for a couple small
problems with Worldpilot.  I'll detail the most
significant first, and see how we do.

When I try to send mail, I get a Zope error with the following traceback:

<!--
Traceback (innermost last):

TypeError: not enough arguments; expected 4, got 1

-->

The problem is obviously (to me anyway) that the call to publish in the def
publish_module
(response = publish(request, module_name, after_list, debug=debug)) is only
getting one
argument instead of four.

I'm not sure I understand why, as this is a bit beyond my current
comprehension of python at the moment.
A gentle push in the right direction would be appreciated.

Thanks,
Matt

Hi all. I've read the Structured Text HOWTO but I'm still having trouble. 

I have a DTML Dccument, stx_about that looks something like:

----
This is my document.

- bullet1
- Bullet2

-----

I'm including that in another DTML Document, about, that looks like:

-----
<dtml-var standard_html_header>

<dtml-var stx_about fmt=structured-text>

<dtml-var standard_html_footer>

-----

but the text isn't coming out formatted. What am I missing?
I've tried many different variants of formatting, with and without blank
spaces inserted between different elements.

Please CC replies to me privately, as I'm not currently subscribed to the

I will have to concur that Philip's book is a very good read. In
addition to his book he has great suggestions for your library of other
books. There are many of his ideas I think are wonderful, however I do
have some philosophical disagreements on others.

Some of his views of computers and programming are somewhat cynical even
if based somewhat on fact.

His version of scalability of which he focuses on a lot is basically
throw lots of money at it.
Start off with a highly scalable, multi-threaded, high quality webserver
with an embedded scripting interpreter. In his case AOLserver with Tcl.
He openly hates Tcl, but doesn't work towards using the language he
likes where he works. Further more he thinks doing so is folly. (my
interpretation) He states relational dbms are the only way to store
data. Other technologies aren't as mature or capable. And on relational
dbs only Oracle is sufficient. With others you are taking unnecessary
risk.

So to scale with Philip you develop with AOLserver/Tcl/ACS, buy big,
expensive hardware, buy big expensive database. ie: throw lots of money.
Since he prefers everything to be in a single machine you can only scale
up processors so much before the $$$ start escalating. Price an 8
processor anything versus a Linux cluster of 8 machines.

This is not enabling for the little guy. Yes I know of the ACS port to
PostgreSQL. I think that's great. However it is going to be a step
behind ArsDigita/ACS because it does require porting to become
PostgreSQL able.

He has disparaging remarks about app servers, many of which are true.
However, I do not necessarily believe that learning Zope/webserver is
more difficult than learning AOLserver/ACS. And when you've got Zope
you've got Python instead of Tcl. For some of us, we like that. :)

As a prodigal son here, I embraced Bobo/Zope early, became concerned
about scalability, wandered the websphere, and have come back home. I
have looked at Java/Servlets/Enhydra, AOLserver/ACS, etc. I decided to
follow my heart. I like Python and Zope. I like the Python and Zope
communities. This is where I want to make a difference and contribute.

Zope can enable the idea person, the little guy with a twinkle in his
eye and a big dream to pursue.

Sure it may not "currently" scale as easily as AOLserver/ACS for big,
busy sites. However, I think it is being worked on. I think that there
are options within Zope, Digital Creations. To a very large extent
Philip solves scalability with $$$dollars.

With Zope you can still throw $$$dollars at Oracle. You can also throw
some at Sybase, or whateverBase you desire. If that gains you
scalability or the ability to sleep at night it's available. With
ArsDigita/ACS the only supported option is Oracle.

If I believed throwing $$$dollars to solve scalability was required. I
would much rather throw $$$dollars at Digital Creations. Instead of a
$20,000 to $500,000 on up license of Oracle which is per machine, per
website, and potentially expires. Instead of requiring buying big, big
hardware for $$$dollars. Throw the money towards Digital Creations or
other Zope or Python developers to solve the issues which hold
Zope/Python back. In the end you will have helped build a bigger, better
open source software solution.

As a little guy with ideas and dreams, this is my view. By the time a
website grows enough to run into scalability and performance problems
with Zope it could potentially be making enough $$$dollars to contribute
to solutions. Try that with AOLserver/ACS/Oracle, start with $$$dollars
and then hope for the best.

My other thoughts wandered into employment. When I master either Zope or
AOLserver/ACS, would I rather work for ArsDigita (yes, they pay well) or
Digital Creations, if an opportunity presented itself in the future. As
I know both are growing companies. I like Digital Creations. :) 

On a side note, on the AOLserver mail list there is effort to embed
Python and get Zope running on AOLserver. I think it would be great to
see Zope/Python being multi-thread, multi-processor able on a high
performance open source, multi-threaded webserver. It would be awesome
to have an embedded Python interpreter in AOLserver without a global
threadlock that worked with AOLserver's multi-threaded API running Zope.

On another side. A website I just learned about does a performance index
of many sites and gives a average amount of time to load pages. This
could put into perspective Zopes performance from the real world, from
your own website.

you need to put HTML comments at the beginning and end of your DTML
methods. These will be passed unchanged to the final page, and any
problems pointed out by your validator will be pinpointed.

The problem is a bit deeper than that. Even if a validator could be
convinced to ignore DTML, you would still have the problem of trying to
analyze an incomplete HTML document.

Message-ID: <000c01bf85fa$bfd07090$0201a8c0@iridium>

Hi,

This question may be very naive but is there any way to use Zope as a
mailing list manager?

The sort of thing I want to do is :

1. Check a mailbox for messages.
2. Grab any that are related to my Zope WebApplication
3. Process each message "request" depending on its content.
4. Send one or more email replies to one or more recipients (easy with what
is already in Zope).

This might allow me to create a simple list manager for instance or allow a
virtual mailbox for all my WebApp members.

I have not followed the discussions you're referring to, so this may be
old news to you, but one simple way to provide XML compliance without
screwing up the HTML is to require that the HTML -- or whatever you're
rendering -- must be properly UTF-8 encoded. This is probably the least
painful way of attaining XML compliance. 

Unfortunately, it *will* be painful unless you're also using an
XML-compliant editor. The low-level DTML source will end up looking a
bit like this:

  &lt;html&gt;
  &lt;head&gt;&lt;title&gt;<var name="title_or_id"/>&lt;/title&gt;
  &lt;/head&gt;
  [...]
  &lt;/html&gt;

The editor takes care of the en-/decoding of character entities.

An obvious alternative is to use XHTML and XML namespaces, which would
currently -- because clients aren't usually XHTML-aware -- incur
additional XHTML-to-HTML processing on the server side.

Just on a personal note: I _like_ the curtesy reply to my personal account.
I redirect mailinglists to their own folder. On a list like Zope, that is
very busy, I would very easily miss replies to my messages.

With a good filter (like I use), I get a personal reply into my In box, not

Subject: [Zope] setting a DTML method's namespace from a product method
Message-ID: <874sameir7.fsf@wiz.wiz>

I'm having some troubles with manipulating the namespace of DTML
methods that are called from methods of product instances.

Some questions:

- How do I provide a DTML method with a full acquisition namespace, as 
if it were called in DTML, when I call it from a product class method?

- Does a REQUEST.set(somevar, somevalue) operation add a variable to
the namespace, or does it re-initialize a new request? I can hardly
imagine the latter.

- Does the local scope of a class method in a product somehow
propagate itself to external DTML methods that are called from that
class method?

Context of my problem:

My product has the following class:

class NFGnav(
	OFS.SimpleItem.Item, 
	Persistent,
	Acquisition.Implicit,
	AccessControl.Role.RoleManager
	): 

which ultimately calls a DTML method:

	  return self.NFGnav_ActiveMapItem(REQUEST)

I can set arguments for the DTML method, no problem:
	  REQUEST.set('NFGnav_ItemTitle', object.title_or_id())
before calling the DTML method works just fine.

However, the DTML method seems to lose it's acquisition context in the 
process. That is, if I define an 'myimage' instance somewhere higher up in
the site hierarchy, I get KeyErrors if I try to call
	<dtml-var myimage>
from the DTML method.

Funny thing is, if I request the URL of the product instance with the
'myimage' appended, this seems to have no problem:
		  /mysite/somefolder/ProductInstance/myimage
returns the image, whereas
		/mysite/somefolder/ProductInstance/someMethod/myimage
gives a KeyError. So the aquisition context seems to be intact at the
product class level, but not at the product class method level. 

I took care to provide (PARENTS, REQUEST) parameters for every class
method invocation, by the way.

I'd appreciate any suggestions in tackling this problem. Is this
question more suited for the zope list or for the zope-dev list, by
the way?

Even simpler than buying new hardware, switch to a system like NetBSD or
FreeBSD that has supported large files for years and years :-)

I'm not sure if you considered this, but note that LD_LIBRARY_PATH needs
to point to *Python's* libraries, not Zopes.  It's not python that can't
find ExtensionClass.so, it's ExtensionClass.so that can't find the
standard Python library module.

Your message sort of implies that you were ensuring that
ExtensionClass.so was in the library path, but the problem (I think) is
that the Python libs are not in your path.

I could be wrong and this could be an entirely unrelated issue.  Can you
run python normally?  Import stuff like cPickle?

Welcome back, Jimmie. I enjoyed reading your analysis and agree with
the thrust of it.

One thing you express, and which seems to have ossified into the current
received wisdom, is that scalability will be improved  when some
mythical deep pockets consulting client pays to get it improved ; then
everyone else will benefit. The problem is with the leap of faith it
requires from the client.

I currently have several clients who are very interested in Zope.
Their web sites already receive megahits. They are willing to pay money
for consulting, but certainly won't bank their businesses on the chance
that a magic key to scalability is found. As a consequence, the
greatest commitment they will make is to install Zope on a Linux server
on a VPN and "see how it goes" in a toy setting.

Therefore, I can testify that right now, today, Zope is being hurt by
the lack of a story on scalability.

If economics or policy dictates that Zope requires an "Angel" to
bankroll scalability research, we all have to be prepared for a
scenario in which that Angel never appears. Personally, I don't like
taking such a passive approach.

Two clear impediments to Zope's wide acceptance have been frequently
discussed on this list -- documentation and performance.

The documentation "story" has travelled on an arc which might be
expressed like this:

* Zope is Open Source. The community should document.
* The community can't take on the deeper Zen issues
* Volunteers from the community are time constrained
* DC hires a technical writer
* The ZDP is formed
* ZDP suffers from the lack of time available to its volunteers
* DC commits Amos to attack the general documentation problem and to
evangelize documentation

Documentation currently seems headed on a good track. What have we
learned from this trajectory? We've all learned that the Zope experiment
is different from other Open Source projects. It *needs* the cooperation
of *both* the Zope community and Zope's authors "shooting at the same
basket" to solve this.

I believe scalability requires a similar coordinated attack and that it
can't wait to be bankrolled.

ZEO, although a bit of a black box to us at the moment, sounds, on
paper, like a logical and credible attack on one aspect of scalability
-- the "throw hardware at it" approach.

No doubt there are other hidden opportunities. What kinds of hidden
opportunities? Who knows; they're hidden. ;>) But can we bring them out
of hiding?

Some of them are simple applications of available compute science, yet
I don't see these codified or set down anywhere. Perhaps we should have
a single HOW-TO repository for techniques and metrics people have
discovered, or just happen to know, in the performance arena. This
would be a FAQ along the lines of "I want to build my Zope site for
best performance. What things should I do? What things should I avoid?"
God knows this question comes up often enough.

Then there's the design and makeup of the Zope software itself. Its
original design requirement probably didn't put scalability at the top
of the stack. Here, there are probably other areas where the user
community can't know enough about inner workings and overall design to
contribute effectively -- but which require attention and a commitment
from the folks at DC. I'll mention a couple of things that pop into my
head. These are simply conjectural -- dialog starters. I'll be happy to
be shown that I'm dead wrong about any of these conjectures.

Zope began as a brilliant notion, of Jim Fulton's devising. It began as
a fews lines of code and has evolved to include better than two
megabytes of code. DC has evolved from a company with one employee to a
company with maybe a dozen engineers contributing to the code
base and is looking to hire twenty more engineers.

Among this team of top notch talent, who takes ultimate responsibility
for evangelizing and improving performance? Who leads the effort at
code review, with an eye to marshalling refactoring efforts?

What would be an example? OK, Devil's Advocate: Here's one area of
concern I have, perhaps unfounded. Digital Creations utilizes Use Cases
as a tool for design, in the Ivor Jacobson tradition. Use Cases have
many proponents and some detractors. One detractor is Bertrand Meyer,
author of the classic _Object-Oriented Software Construction_. His beef
with the use of Use Cases is that it poses a fundamental risk: it
encourages a functional approach, based on processes (actions). He sees
this as the reverse of O-O decomposition, which focuses on data
abstraction. He believes it carries a risk of reverting, under the
heading of object-oriented development, to the traditional forms of
functional design, by considering what the system does, rather than
what it does it to. He believes that, due to this risk, Use Cases
should be confined to use as a validation tool, not a design tool, to
avoid closing interfaces prematurely.

So let's say that Use Cases is a useful tool, but one that has a subtle
built-in gotcha. What are the dangers? Naturally, one is negative
impact on code maintainability/reusability.

Another may arise due to the need to balance two competing technical
concerns: the desire to encapsulate abstractions, and the need to make
certain abstractions visible to other modules. With regard to the
dynamics of subprogram calls, the placement of declarations within
modules can greatly affect the locality of reference and thus the
paging behavior of a virtual memory system. Poor locality happens when
subprogram calls occur across segments and lead to cache misses and
page thrashing, which can ultimately slow down the whole system.

Is Zope prey to this? I don't have a clue. Does anyone? Like I say, I'd
be happy to be shown that this concern is unfounded. But this is the
sort of creeping problem which can enter into a growing code base like
Zope's, as it is worked on by numerous people, each devoted on one
module or interface. Combatting such problems probably requires having
someone (someone blessed with both Jim Fulton's dedication to O-O
principles and an unbending zealotry for absolute performance)
committed to periodically flying above the code at a sufficient
distance to see such patterns and making bombing runs against the
target problems. As busy as everyone at DC is, I'm not certain that
anyone is doing that at the moment.

Thanks for the replies!

I did get it to work.  Here is what i did:





I created a new python method inside my primary class:

    def is_local_name(self, name):
        """ returns true with ID if name is a local user
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rlist = filter(lambda x,p=self,s=thisdjname : p.data[x].name == s,
rlist)
        return rlist






then called it using this dtml:

<dtml-if namelist>
  <dtml-in namelist>
   <dtml-let thisname=sequence-item>
    <dtml-if "is_local_name(_['sequence-item'])">
     <dtml-in "is_local_name(_['sequence-item'])">
       <A HREF="<dtml-var site_url>/<dtml-var

     </dtml-in>
    <dtml-else><dtml-var sequence-item><BR>

I checked the WU IMAP mailing list, and found the following:

  http://www.washington.edu/imap/listarch/msg06947.html

In short, Mark Crispin (the author of WU IMAP) strongly recommends avoiding the
"*" wildcard altogether, using rather "%".  In this case, the '\NoSelect' flag
indicates (I think) that the item is a directory, and could be drilled into; 
or  perhaps the '\NoInferiors' says "this is a leaf -- don't descend" (my
ignorance of the IMAP protocol is showing).

I guess the idea here is to avoid using LIST once, but to do it "on demand" as
the user drills down the tree.  Mark also recommends using "LSUB" to pick up
"subscribed" mail folders.

Hope this helps!

Tres.

StructuredText expects list elements to be separate "paragraphs", where the
paragraph separator is an empty line.  Also, the indentation determines whether
the line before the list elements is treated as a header or as a paragraph.
Try::

 This is my document.
 
 - bullet1

 - Bullet2

which makes the preceding line a paragraph, or::

 Header Goes Here!
 
   - bullet1

   - Bullet2

Many thanks to Michael the author of TTImage
for pubishing your Product at zope.org.
You did a great job !

In order to create TTImage instances within DTML-Documents I made
some changes on TTImageClass_add because I got errors due to
empty BasicProps and DestinationURL.
Would be nice if you could include it in your next release.

I´m new with Python and especially with PIL so at the moment it´s 
not so easy for me to fix some further problems with the background
color.
When I set the backgroung color to 0xffffff the background color of the 
result is 0xfcfcfc ... seems to be an color palette problem ...   

Also I was wondering if it is possible to set the background to
transparent ?

I look forward to hearing your thoughts on my changes :-)

Hi Matt!

I ran into this same problem. I finally traced it to a problem in the IMAP and
SMTP server options set in the setup screen. It seems to work best when these
are explicitly set to localhost and localhost. I'm not sure why but that's how
I got it to stop giving me that particular error. Unfortunately it will require
removing the current WorldPilot object and replacing it with a new one since
those parameters are not visible on the parameter tab of the object.

Good Luck!

Thanks, however I think they only work on date objects.

There is a DateTime() function to create date objects mentioned in the
DTML guide, but it doesn't seem to be documented.

Nevertheless, I would be interested in why atoi does not work for me.

Okay, it's simple enough - 

<dtml-call "REQUEST.set('mydate',_.DateTime('2000/12/31'))">

creates the date object I need to then reformat it.

Message-ID: <38C1E1C8.6C56365E@texoma.net>

Thanks,

It was never my intention to imply that throwing $$$dollars at DC was
required to improve scalability. What I said was based on perception of
such requirement. I'll admit "currently" Zope does not scale as well or
as elegantly as I would like. A statement I was making was that "if" I
(or anyone) "believed" that scalability == $$$dollars, I would rather
give to DC than Oracle. I believe Larry is doing all right on his own.
:)

I find Oracle pricing obscene. For the kind of $dollars it would take to
license Oracle I would rather see what DC could do with the additional
employees on beefing up Zope/ZODBs concurrency/scalabilities. There is a
thread on the WebDB forum about a group of people talking about putting
together a co-op to buy an Oracle license based on Oracles "unit"
pricing scheme for a moderately powered single processor Intel machine
it was going to run about $20,000. You would have to renegotiate if your
site got busy and you added a processor. Yuck!

I believe Zope's scalability issues will be solved over time regardless
of external $dollars. I believe more $dollars could speed up the
process, however it will still take some time. Currently ZEO is an
option but I don't know how well understood it is by the community.

Scalability Now can still be a sticky wicket.

Future things on Zope's side:
1. Moore's law.
2. Advances in Python and it's performance.
   a. Python becomes fully multi-threaded, multi-processorable.
   b. Stackless Python gets adopted and performance improves.
   c. Viper 
3. Advances in Zope, it's architecture and performance.
   a. Sam Rushing works miracles on Medusa/Zserver using Stackless
Python and Continuations.
   b. Zope does process pooling with each process on a different
processor. ZEO?
   c. ZODB does multiple data.fs's based on user design based on url
path directories
        allowing different Zope processes on different processors to
handle their respective dir.

It would be nice if some C/Python programming guru/genius would solve
Python's global threadlock issues where Python would scale on
multiprocessor machines. This would potentially render scalability a
moot point. The geniuses at AOLserver rewrote the threading of the
built-in Tcl interpreter so that it would be multi-threaded and work
properly with their nice multi-threaded webserver. Tcl's standard
threading I don't think (I could be wrong) is as nice as Python's.

If I had Oracle kind of money to throw around I would like to see
Python's thread issue resolved where Python becomes fully
multi-processorable. That would transparently scale Zope and benefit
other Python user's as well. It would enable Python/Zope to embed well
and play nice in multi-threaded webservers like AOLserver and others.
IIRC Apache 2.0 will be multi-threaded. If Python scaled on
multi-processors even a little guy could put together a dual-celery
machine a serve a nice site.

I agree wholeheartedly with you that there should be a concerted
coordinated effort between DC and the community to improve scalability
by allowing people to throw hardware at it. That was the primary issue
causing me to wander the websphere looking at options. I've learned some
things in the search, but I always looked back at Zope, even tho' my
wife liked Enhydra's logo, she thinks the otter is cute. Zope's current
logo is much nicer than the Purple and Gold. :)

If ZEO currently scales well, then DC needs some testimonials on their
website.

There definitely needs to be some documentation best ways to...
As you said, there is a consistent recurring thread of is ZServer alone
or ZServer behind Apache better.
Should I use a RDBMS or ZODB.
...

Some of us have no legacy issues. From scratch what's the best way to
design...

I agree the solving of Performance/Scalability and Documentation issues
would definitely help convert lookers into believers.

I am currently working my way through the docs and plan on helping
there.

While I was wandering, in my heart Zope was the project I wanted to see
succeed. I decided to put my mind where my heart was.  Possibly someday
some of my money too. :)

Some of your other concerns I can't address. However, one of the nice
things about Zope is that it is written in Python. Python imminently
supports playing and algorithm improvement. :)

Oops, spoke too soon.  Spent the last few hours trying to suss this out
without any progress :-(

I have a variable called START returned by a sqlquery

<dtml-call "REQUEST.set('startdate',START)">
start is <dtml-var startdate>

and that's okay

<dtml-call "REQUEST.set('month',_.DateTime(startdate).aMonth">

That, and variations of the same, dies with

Error Type: TypeError
Error Value: __div__ nor __rdiv__ defined for these operands

Why is that these simple little things are so difficult in Zope?

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

FreeBSD on intel architecture doesn't have the large file limit of Linux.

Not exactly true.  The *BSD's, like most of the rest of the world,
implement the basic POSIX file APIs which use a signed 32bit long
for file offsets in the base ABIs.  Ergo. if you are using the
equivalent of C's fseek(...SEEK_SET) (from beginning of file), you
are explicitly limited in the maximum size files you can process.

There are multiple hacked ways to work around this, one of which is
to allow offsets from SEEK_CUR to page-flip out into longer files
(just never use a SEEK_SET), or to implement another, parallel ABI
which takes a 63/64bit offset value.  Neither of which however helps 
the poor application which merely expected standards compliant
behaviour from its host and therefore didn't play by the local
"special rules",

Not completely correct.

man lseek... it doesn't work on file streams (fopen ), it works on 
file descriptors like poll and select,  and, it works on very very large files.

lseek is a POSIX interface, and has been a part of linux since at least 1995.
Indeed the BSD and Linux manpages are basically identical including this as 
a bug:

No, a Redirect is a client side thing. The response will tell your browser

You have to start up your Zope install in non-debug mode. By default, it is
started with the -D flag (see you start script). Remove that flag, and all
your tracebacks will be demoted to HTML comments.

Yup. Take a look at REQUEST.environ['HTTP_USER_AGENT'], which is also
accessible as:

  REQUEST.HTTP_USER_AGENT
  REQUEST['HTTP_USER_AGENT']

and in DTML also as

  HTTP_USER_AGENT

You may want to take a look at this doc:

On Zope 2.1.4 (Win 32):
- I get "1900/02/28" when entering "2/28/00".
- I get "2000/02/28" when entering  "2/28/2000".

No errors. (I tested this on the Properties tab of a DTML Document).

The issue you report seems to be corrected in the last Zope subversion.

Hello Tim,


- To get the modify time for a file, use this code in a DTML document or 
method:

<dtml-with yourFileName>
   <dtml-var bobobase_modification_time>
</dtml-with>

or
<dtml-var "yourFileName.bobobase_modification_time()">


- If your filename includes a dot, use instead:

<dtml-with "_['yourFileName.gif']">
   <dtml-var bobobase_modification_time>
</dtml-with>

or

<dtml-var "_['yourFileName.gif'].bobobase_modification_time()">

Hi !

I have added this as a FAQ to 

http://zdp.zope.org/projects/zfaq/faq/DTML#952258570

As ZDP members you can become Maintainer of the question
and answer objects.

Greetings,

Maik Röder

   How do I use bobobase_modification_time on a file object ? 
                      
   To get the modify time for a file, use this code in a DTML
   document or method : 

   <dtml-with yourFileName>                                          
   <dtml-var bobobase_modification_time>                            
   </dtml-with>                                                           

   or 

   <dtml-var "yourFileName.bobobase_modification_time()">

   If your filename includes a dot, use instead: 

   <dtml-with "_['yourFileName.gif']">
     <dtml-var bobobase_modification_time>
   </dtml-with>

   or 

   <dtml-var "_['yourFileName.gif'].bobobase_modification_time()">

I want to do the following tasks

A user enters a list of products. Such a list is equivalent to
an order. Then i want the user to enter some things for each
product. I don't want to implement DTML pages for each
combination of products and i want to present one entry
screen for each order.

I tried the following approach:
I created a Folder named 'Products'. In this folder i
created subfolders named after the prducts code number,
e.g. `4007', `4008'., ....

In each of these folders i defined a DTML Method `New' which
hholds the DTML code to create an input form fr this product. My
plan is also to create methods named 'Display', 'Edit', .... so
i can render the objects in different ways.

In anotehr page i want to do something like:

<dtml-in products>
   <dtml-var "URL1 + '/Products/' + _['sequence-item'] + '/New'">
</dtml-in>


but this doesn't work. Nothing is displayed. I also tries
<dtml-var expr="...."> and <dtml-call "..."> (the last one
was pure desperation).


So what's the correct method for implementig such a system?

[many good points cut away]

| I don't like Dynamo, but I acknowledge its technical edge on Zope
| (and other solutions) in several areas, such as clustering,
| reporting, personalization services, e-commerce services, stability,
| and raw speed.

Not that I have very much to base a comparison on, but I regard Zope
as both stable and fairly speedy.  I think I can guess in what regards
an alternative could be faster, but I'd really appreciate to learn
where Zope lacks in stability.  Can you provide any references?

I don't quite grok what "the situation" is referring to, but I think
you're wrong here, or at least mistaken regarding the meaning of
"proprietary".  Proprietary, according to Merriam-Webster, means this:

[cut from Merriam-Webster]
Function: adjective
Etymology: Late Latin proprietarius, from Latin proprietas property --

I'm not sure if I agree it's a problem, then, that Zope lacks in the
big-department. :-)

| [under Zope's surface] lies a powerful engine with scalability
| problems.

What part of Zope's engine are you referring to here?  Do you mean
Python in general, are some specific part?  Like ZODB?

| So far the only way to scale properly with Zope is a combination of
| a load-balancing clustering system (eg., TurboLinux' TurboCluster
| Server, which I can personally vouch for -- brilliant stuff -- or
| Linux Virtual Server) with Digital Creations' ZEO, of which I've
| only read about.

I actually thought of ZEO as a very nice way to scale Zope.

| There are Zope sites out there that are suffering scalability

It would be very much appreciated if you could share some specifics.

You are right about that, and I think that's a better way to provide
such support, rather then building specific support for any of them
into Zope.

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

A more zopish would be: define your 'New', 'Display' and 'Edit' methods
in the Products folder and use properties in the subfolders for the
different rendering. For example:

give each subfolder a property 'Description', and a property 'Price', in
your Display method put something like:

Description: <dtml-var Description><br>
Costs: <dtml-var Price>

So, with an url http://yourhost/Products/4007/Display

Display is rendered in the context of the object '4007' and its
properties will be used.

This is a bit unclear. Where do you call it (note that Zope doesn't know
'pages', it only knows objects, which define what's going on) and where
does the 'products' come from? I assume you want something like this:

<dtml-in "objectValues(['Folder'])"> 
   <dtml-var absolute_url>/New <dtml-var title_or_id><br>
</dtml-in>

objectValues(['Folder']) gives a list of all (sub)folders of the current
object. Note, that if you put this into a DTML Document, the list will
be empty, because a DTML Document is an object by itself, which has no
folders associated with. You'll need in an DTML Document a <dtml-with
"PARENTS[0]">, this will include the namespace of the folder object,
where the DTML Document is called from.

For each found item <dtml-var absolute_url> displays the absolute url

Generally, this sounds like a typical ZClass task. Have a look into the
ZClass tutorial and into the example products (there is one called the
boring product on Zope.org) for more informations.

Is START being returned as a string, or as a DateTime from your query? If
it's being returned as a string, you need:

  <dtml-call "REQUEST.set('startdate', _.DateTime(START))">

aMonth() is a method, not an attribute. You need to _call_ it, i.e.:

  <dtml-call "REQUEST.set('month', _.DateTime(startdate).aMonth())">

or, if startdate is already a DateTime:

  <dtml-call "REQUEST.set('month', startdate.aMonth())">

Another way of doing this, however, is something like the following:

  <dtml-call "REQUEST.set('mydate', _.DateTime('2000/12/31'))">
  <dtml-var mydate fmt=dd>-<dtml-var mydate fmt=aMonth>-<dtml-var mydate
fmt=year>

Voila.

> Why is that these simple little things are so difficult in Zope?

The above does not seem too difficult to me. You made a few simple
mistakes, that's all.

I forgot that you can also use C-style formatting, which reads much better
in this case:

  <dtml-var mydate fmt="%d-%b-%Y">

Try (untested):

I would investigate ZClasses. It seems to me like you could end up with a
"Product" ZClass (though I might call it something else to avoid confusion
with Zope Products), which contains your New, Edit, and Display methods.

Depending on how much each Product differs, you might have a
WidgetProduct, ThingamabobProduct, DoohickeyProduct, etc. Or, maybe you
can just get away with Product. I'd have to know more specifics to get
into detail.

I'm a relative beginner to Zope, so I'm not sure what I'm talking
about <grin>, but it seems to me from my limited experience that
you can't call out an object using a URL in a dtml-var.  Instead
you need an object reference.  So try something along these
lines (this is untested because I'm in the middle of my own
debugging mess):

<dtml-in products>
  <dtml-var "Products.get_item(_['sequence-item'],0).New"
</dtml-in>

I'm sure the above is not right from a Zope standpoint, and
the Python is probably wrong too, but maybe it will send you in
in the right direction.  What I'm aming for with that psuedo code
is to get the property of Products whose name is in sequence-item,
without rendering it (that's the ',0' bit), and to pick up
*its* 'New' property and render that.  Maybe a real Zope expert
can correct my code.

Or more likely, as others have suggested, using a ZClass is the
right direction anyway, which would avoid the whole syntax issue
<grin>.

It works as written

<dtml-call "REQUEST.set('month',_.DateTime(startdate).aMonth">

Subject: [Zope] More search engine woes
Message-ID: <E12RiXK-0007iL-00@ethereal>

I'm not sure if this is a PTK-specific issue, but I'm starting to
believe that it isn't. So I thought I'd post here with my problem and
see if someone could possibly point me in the right direction. I also
unsubscribed from the list recently, so please CC me with any replies.

I'm using Zope on a student organization website which I am
developing. Ideally I'd like for this to be an extremely popular
community-driven site, so a working search engine would be a
necessity. Additionally, I'd like to exclude unapproved items from
searches so that only moderated content is placed in the queue of news
items and ad banners which are being indexed. I'm also writing
site-specific documentation which is intended to guide members through
the process of creating news items, ad banners, etc., and I'd very
much like to have this content indexed as well.

Today I noticed that my search engine failed to produce any
results. Searching for the letter 'e' didn't even reveal anything,
which is unusual since E is the most common letter in the English
language AFAIK. So I tried digging into the ZCatalog documentation,
and poking around in the interface has confused me.

I created a help folder, and added an advertising document which
briefly explains how to create news items and such. Yet, I can't seem
to get this item to appear in the ZCatalog. In fact, the only item
which does appear is /Members/nolan, my PTK account page. Clicking on
the "find" tab and checking the "all items" checkbox seems to imply
that all items of every type on my site will be cataloged, but doing
this always results in only one page being listed in the catalog. Is
there some reason why the contents of help/ aren't being listed?

Thanks a bunch. If I can provide any additional information then I
will be glad to do so.

Ran into this one myself - the solution is to remove the DocumentRoot
directive, then just use the SetHandler and similar tags in the body
of the config file, though you can put them in a location container if 
you like.

Subject: [Zope] Setting attribute from DTML method in ZClass
Message-ID: <20000305223451.A15162@mimar.demon.nl>

Hi,

I've created a ZClass with a method 'force_update'. When a user is viewing
an object, there is a formbutton which they can press and force_update is
then called. So far it works. What I want my force_update to do, is that
it should set the needs_check (type boolean) in the object to true.
With <dtml-if needs_check> I print different things depending on whether
the object needs a check. From the Property sheet I can change the
settings. 

So, how do I put something like this().needs_check = 1 in a dtml-method?

Greetings,
    Chris Niekel

Subject: [Zope] zclass instance "broken" on copy/paste?
Message-ID: <010301bf86f3$d507db20$c3f28ec6@hikari.anu.edu.au>

I have a ZClass (Shot) which is nested beneath
a container ZClass (Storyboard).  I.e., an
instance of Storyboard might be:

Scene1 (Storyboard)
 - shot1 (Shot)
 - shot2 (Shot)
 - shot3 (Shot) ...

For reasons that I cannot discern, copying and pasting 
instances of Shot does not work.  I can copy them, but 
pasting creates a broken object:

  "This object is broken because the unknown product that 
   created it is no longer installed or is installed 
   incorrectly."

I suspect the copy has in fact worked because the title
in brackets is that of the source object.  This is an 
isolated problem on my site.  All other nested Zclasses 
work fine but I cannot pin down the difference.  This is 
Zope 2.1.4.

Has anyone else encountered this problem?

Darran.

Subject: [Zope] Simple Z Search Question - lost something while renaming
Message-ID: <000601bf86f4$06c5c5f0$0100a8c0@pinol1.sfba.home.com>

I'm trying to determine what might have failed in a Z Search generated set
of objects.

I used the Z Search wizard to create the search interface and tabular
report. They ran fine. I then renamed the data source (odbc) and both the Z
Search generated objects. I made sure that the input form reflected the new
report name. Now the input form will come up but when attempting to search I
get a "Object Doesn't Exist" type error.

I've also recreated the tabular report and it's input form with the Z Search
interface, and of course they work. I think the problem is with the report
as the original input form will sucessfully populate the recreated report.
What's interesting is that a compare of the text in the original vs the new
Z Search created report object show that they contain identical text.

I've also used Z Search to creat a similar "record" format pair of objects
that seem to endure any number of renamings, which is puzzling too.

I think that there are some variables hidden away, properties, whatever,
that I can't get to. This is probably pretty transparent to everyone, but
it's a bit of a stumper for me. In general this is a useful experiment as
it's obviously very important to know what effect name changes will have.
The docs state something to the effect that it's not too wise to change
names, but I've also seen that some name changes are propagated. So it would
be great to know what the pattern is. Maybe it's as simple as "rename at
your own risk".

Message-ID: <00030608295700.14008@tokey.kedai.com.my>

hi all,

i installed fastcgi on my server and added -appconntimeout 0 (as suggested by
ppetru).  tried both unix and tcp socket.  however, i can't get 100%
availability.  there still exist connection failed (connection refused) errors
and incomplete headers 0 errors.

my config
rhl 6.1, pIII 500M, 776M RAM, oct6 fastcgi snapshot, FCGIServer.py from cvs ver
1.7, zope 2.1.3

i glanced at FCGIServer.py.  there were references of max connection (10) and
max request(50).  will this have any bearing on the connection refused error?

do i need to d/l other files instead of only FCGIServer.py?
i am also considering mod_pcgi2.  can anybody with fastcgi and mod_pcgi2
experience enlighten me?

This how-to will give you all the details:
http://www.zope.org/Members/lstaffor/zProperties

The short of it is that you need to call manage_changeProperties for the
propertysheet in question (which is actually what you need to do in Python
as well).

<dtml-call
"propertysheets.YourPropSheet.manage_changeProperties({'needs_check' : 1})">

It is very stable, indeed, so I take that back. ;-)

There are cases where I have been forced to kill Zope processes that
have falled into some sort of coma, but I've written these off as
growing pains in an evolving product. ;-) To date, Zope's stability
problems seem to have been mostly related to fragile database drivers.

I was really thinking of something else, and should have used another
phrase -- something like "high availability". Again, I have only read
the marketing material on ZEO, the product that supposedly provides such
features (load balancing, replication). Assuming ZEO works, strike that
from my list.

What I've observed is that I'm running Zope on Linux and accessing it from
a browser on a Windows box. I can create empty File objects and file
objects containing _text_ files without a problem, but as soon as I try and
include or upload an _.exe_ file it barfs with the commit_sub error.
I'm wondering whether there's something occuring inside the .exe file
that's playing up with the storage mechanism, maybe some kind of terminator
or something...

(I tried uploading files from Solaris and uploaded text files from there
fine, so I was thinking it was a windows problem, but upon trying them text
files worked under windows as well. It definitely seems to be an exe
problem instead.)

I mean proprietary as being controlled by a private party -- owned, in a
very liberal sense -- as opposed to being standarized. XML is not
proprietary. DTML and Java are.

I'm not as knowledge about IP laws as I would like to be, so I can't
really defend my use of this word or whether DTML is an intellectual
property of Digital Creations. Perhaps somebody else more suited to the
task could clarify.

If the suits in managements (assuming you work in such a place) tell you
to go learn Dynamo because that's what they want to use, wouldn't you
say it's a problem?

I definitely believe that Python is Zope's largest problem right now.
It's also, from a technical point of view, one of it's biggest assets --
Zope is becoming the killer application of Python, and might eventually
become the driving force to evolve Python, which is, I believe,
suffering from draught into the contributor department. Skilled
developers aren't flocking to Python to make it faster. Not right now,
anyway.

My hope is that Zope will change this, because Python has possibly one
of the slowest interpreters on earth. Python zealots -- and there is
such a beast -- will tell you that Python's performance is less of a
matter because what you sacrifice in speed you gain in power, ie.
computational expressiveness through a high-level, dynamic language.

For an example of a good, Python-like, dynamic language that is also
very fast, take a look at Dylan. In current implementations, Dylan is
not interpreted but rather compiled to native code, but in theory there
is nothing stopping anyone from writing a highly efficient Dylan
interpreter. Dylan's magic comes from its use of type hints, a system
which I had recognized as likely pivotal to improving Python's
interpreter long before I knew of Dylan. In Dylan, specifying a
variable's type is optional. When omitted, the Dylan compiler will
usually be able to infer the type from what you do with the variable
(ie., it sees you're assigning an integer to it; hence it can assume
that, for at least a stretch of execution, the variable remains an
integer). When you explicitly declare a variable's type, Dylan applies
the necessary code optimizations (such as using tight integer maths or
string copying) as well as static type checking. In Python, variables
can hold virtually anything, and this incurs a huge amount of checks.

Just imagine -- while Zope is running, thousands and thousands of the
same little checks are performed continuously, over and over again,
amounting to no uncertain overhead.

Python's biggest overhead comes from its dynamism -- the dynamic typing,
as explained, combined the object allocation system: most things is an
object, so a lot of objects are constantly spawned and torn down, often
in rapid succession because the compiler/interpreter can make few hard
analyses of when stuff is needed. Python also has a high function-call
overhead.

No. Ask around, do some research. Ask Digital Creations -- they probably
know of a few, although I'm guessing that they might feel it would hurt
their reputation to tell. Many companies using Zope might not want to
tell you because it would hurt their position, especially if they're
public companies.

Here's one specific case that I'm personally struggling with. I have a
page that returns a large number of dynamic database results in a
relatively simple table. The results are first munged by a small Python
script. This stuff is slow. Internally, as far as I can determine
(through shallow study of the database code), Zope allocates a row
object for every row you access -- even if the row has been returned
earlier on. Zope has a 1-row cache for cases when you repeatedly ask for
the same row in succession. Zope also has a row cache that is useful for
static result sets. Yet, for dynamic result sets, the processing
overhead is huge. The overhead isn't so higher than any other overhead
in other areas in Zope, but it's especially painful here, because it
affects the generation time of a single page, whereas other kinds of
overhead are more evenly distributed across multiple pages and multiple
users.

Exactly. However, the necessary counters must be built into Zope at some
point, and exposed through a common (XML? Python/XML-RPC?) API. Then we
could attach publishers for SNMP, HTML, XML, whatever.

Which reminds me. Does Zope have a mechanism for extending the
Control_Panel namespace other than through the Product sub-folder? I'm
too lazy to check, and I don't remember if this was ever discussed.

I need record level locking in a database, and I need it quickly, without having
a huge learning curve or added cost of administration.  What do folks out there
recommend.  Does Postgres allow record level locking?  I am on a linux platform,
and refuse to use any MS products, so don't go there.  Additionally, I need to
be able to easily export database content as both SQL statements and in some
sort of delimited text file format.  I can do the latter with Zope, of course,
but it is fairly slow and expensive.  MySQL does all of that nicely, but doesn't
have record level locking.  Please respond to me as well as the list.

Subject: [Zope] Zope Documentation Project (ZDP) Announcement
Message-ID: <38C31F68.123691B3@berg.net>

Dear Zopistas,


The Zope Documentation Project is pleased to announce the availability of
the new zdp.zope.org website, which aims to give the Zope community
an additional place for sharing knowledge, and for working together
on providing good Zope documentation. The new ZDP homepage already contains
many useful resources for the Zope community, which for the most part
complement the already existing types of documentation available on zope.org. 

We sincerely hope that Digital Creations will play an active role in
the Zope Documentation Project and help merging the existing Zope documentation
with the documentation provided via ZDP. To see what Digital Creation's Plans
for Zope Documentation are, have a look at:
http://www.zope.org/Members/Amos/Documentation/Plan

When we built the new ZDP site, great emphasis was placed on providing
ways to easily get aware of what is new on the site and to quickly get
an overview of what pieces of documentation need Maintainers, Writers,
Commenters and Reviewers. Thereby contributors are directed to the
documents and projects that need help. Everyone can contribute according
to their interest and level of experience.

We invite you to join the ZDP and to help building up a great
knowledge base on Zope. This also includes helping to customize and 
extend the ZDP-Tools, which is the software with which the ZDP site
was built and on which it runs. The ZDP-Tools are being developed 
on-site, and are completely written in DTML to allow for rapid 
through-the-web programming. Questions on the ZDP tools can either 
be directed to the ZDP mailing list or to me, as I am the ZDP-Tools
maintainer (Maik Röder, roeder@berg.net).

The most important sub-projects of the Zope Documentation Project are:

1. ZBook

   In this project, we are collaboratively writing a book about Zope.
   There are already many chapters, most of which are still drafts.
   We need feedback on these drafts, so maybe you can give some 
   comments directly on the drafts, or discuss them on the ZDP mailing
   list or directly with the author. The ZBook project is maintained 
   by Tom Deprez (tom.deprez@uz.kuleuven.ac.be). 

2. ZFAQ

   This project tries to answer the frequently asked questions on Zope.
   The project is in need of additional contributors, so if you
   have a  question on Zope, or an answer to share, then you are
   welcome to add it to the ZFAQ. If you want to help moving the old
   Zope FAQ  to the new one, then just contact Kamon Ayeva
   (kamon.ayeva@bureauveritas.com), the maintainer of the ZFAQ project.

3. ZSnippets

   Snippets are short pieces of DTML or Python code which come with a
   description of their purpose and how they work. This project is
   maintained by Rik Hoekstra (rik.hoekstra@inghist.nl), who will get
   an automatic email notification when you add a Snippet, so you are
   invited to help flooding his inbox ;-)

To become a ZDP member, write an email to the ZDP mailing list (zdp@zope.org),
and we will create an account for you. For the time being, this will give
you Manager rights on zdp.zope.org. Once we use a tool like the forthcoming
PTK Login Manager for automatically adding new members, we will have to
give more restricted access rights.

Thanks go out to Digital Creations for sponsoring the ZDP server at Codeit
Computing (http://www.codeit.com), a Zope Hosting Provider which is
kindly giving the ZDP project commercial support for an Advanced Zope
Hosting Server !

The ZDP site has not been tested under heavy load, so just in case 
you should experience down times, please report to the ZDP mailing list
at zdp@zope.org, and come back later. If you should not be able to 
reach this site under the name zdp.zope.org, try using the IP address
209.185.210.24 in the meantime.


So, you are invited to visit us at:

http://zdp.zope.org


Best Regards,

Maik Röder

"Update" and call manage_upload on a particular file object when it's
clicked. Ideas?

Subject: [Zope] AS400, DB2 and Zope
Message-ID: <20000306032022.4041.qmail@www.eventera.com>

I am putting together a proposal for a steel, cooper and plastics
manufacturer based out of Germany, but with a large IT shop in 
Detroit. They are looking at Uniface Web Application Server, from 
Compuware, to do their web work. Although they approached me for 
my Uniface expertise, they seem open minded toward Zope. This is
their first experience building an application on the internet. 

Thier data is stored in a DB2 database on an AS400. While I have
used DB2, that has only been on MVS (don't the call it OS/390 now?,
am I dating myself?), and I was never the DBA. They seem to be
open minded about the operating system for deploying the web
application server, but I suspect that they will want to use
Solaris. I gues I am nervous because I don't know what I need
to know, and I don't have a AS400 laying around to play with.

Is ODBC an option for talking to DB2 on an AS400 from a Solaris 
box running Zope? How about from a linux box running Zope? Has
anyone heard the news on the OCI-based driver that DC promised
"real soon now" at the IPC8? Does anyone have that working?

I am going to pitch Zope and this project proposal on March 17.
There is a lot of money on the line, I appreciate any assitance and
my memory is long. If appropriate, please resond to me in private.

Thanks,

Greetings,


Look, I don't want to start any holy wars, just to get a head count, more or
less.  But what are peoples preferred browsers for ZOPE development?

Until now, I've been using Netscape, whilst desperately searching for some
replacement that didn't haemorhage memory.  I think I've even managed to narrow
down which part of NS is losing the memory (it's the edit box, which is why it
seems to happen quicker when working with ZOPE).

However, in my searches I've yet to find ANYTHING under Linux that comes close
to the functionality of NS.

As I said... I don't want advocacy here, simply name and version, and perhaps
a quick rundown of the reason(s) you chose it over others.

Yep. In fact it goes quite a bit further:

It uses a BSD license so it's even more libre/lucre free than MySQL.

Er... do you mean ' I need to be able to easily export database

delimited text file format.'?

Or transactions, or constraits beyond NOT NULL and UNIQUE, or triggers 
or rules, or arrays or a dozen other things you'll wonder how you ever 
did without when you where using MySQL :-)

I'm running pretty much the same thing except for Zope 2.1.4.  I haven't had
any of the problems you describe.  I don't know if FastCGI changed from
2.1.3 or not, and I've only been using tcp socket.  I know this doesn't
really help solve your problem, but it does indicate that your setup

This is such a stupid question, but I can't seem to figure it out from

don't mean containing like a folder, I mean one object referencing
another in a different part of the hierarchy.  For example, if I make a
class to represent movies, and another to represent theaters and I want
the movies to reference the theaters they're playing at and vice versa. 
How does Zope handle this?

Please try to frame an answer in the context of ZClasses, since that's
what I'm using.  (Or tell me if ZClasses can't do this yet.)

Well, you see... here's my problem.  I am using NS 4.7 on Linux.  And it chews
up memory like it's going out of style.  If I don't keep an eye on it, I wind
up in a swap-frenzy, and having to wait up to 5 minutes for response to any
keystroke (always the "KILL THE DAMN APP" keystroke :)

As for IE, i've had no 'back' problems with it when i do work from home (that
box is mostly for playing, so why not have a toy OS ? :)

Message-ID: <3.0.6.32.20000306100909.00920070@poirot>

Help,

perhaps somebody from DC can help me swiftly?

Is it possible to use your own manage_afterAdd method in a ZClass which is
a descendant of CatalogAware Class? If so, how can you get this done?

Does there exist something like 'inherited manage_afterAdd', like in other
Object languages (eg Delphi?) : eg:

def manage_afterAdd ....
  <blablabla my stuff blabla>
  inherited (and does now performs the method from the parent class)


this doesn't seem to work :

def manage_afterAdd ...
  <my stuff>
  catalogAware.manage_afterAdd ... 

Help! Thanks in advance!

Tom.

Subject: [Zope] A zope fear...
Message-ID: <20000306033837.A12534@devware.com>

Several times I have heard folks mention a fear of "not being able to
get my files OUT of zope once they are in there." And usually the
answer is "Well just back up your Data.fs file and don't worry about
it."  I think perhaps this answer doesn't actually address the root
concern.  I think the root concern is one that I am actually coming up
against right now in debates about using Zope for a project.  That is,
if I stick with scripting languages or other traditional languages, if
I need to, I can always fall back on text processing tools to make
large global changes to my projects.  How can I do this with zope?
Many of us programmers are taught to learn to manipulate text like
magic.  Zope seems to take that power away from us.

So, the real heart of my question here is: I just spent 3 months
building a web site using Zope.  Suddenly, we decide to change our
database schema, and I now have to go through and change all 400 of my
SQL methods in zope.  How can I automate this process?  How can I do
this just like a good-ole multi file search and replace?

Answers that don't count are: Use the find mechanism built into
zope. - It's not powerful enough for this.

Another: Your design shouldn't have relied on something that would
change. - Well, it happens, now how do I fix it?

A secondary question here is, what about "software configuration
management" and zope?  What if I need to return to an exact version of
my web site for testing a certain bug that's now cropped up at a
customer site.  What's the easiest way to automate keeping old
versions around without having to roll back my current changes.  That
is, without using the built in versioning?  (Sorry, CVS *is* more
powerful in some cases)

Message-ID: <Pine.GS4.4.21.0003051530570.6405-100000@jeeves.stud.ntnu.no>

Zopistas,

I have a small problem here regarding uploading of files. We're setting up
a site where people can upload their MP3 files. We've tested everything on
our site, and everything seemed to work fine - until people started
uploading with modems.

They get timeouts, server not found etc. after around 5 minutes of
uploading. First we thought that it might be because of our proxy setup
with apache or - less likely - the external python method that handles
the file, but when I dug out my old 14.4Kbps modem and tried uploading
a 4MB file directly into Zope at port 9090, I got the same errors.

Is there any kind of timeout settings in the ZServer I can tweak?
Or is there something else going on?

Please help! This is very frustrating, as 90% of our users are modem
users...

Thanks in advance,


Alexander Limi
http://mp3.no


For reference, our setup is as follows:

We run an apache server which forwards all requests to mp3.no:80 to
login.mp3.no:9090. In other words, we use apache as a proxy for the
ZServer. When we try to upload a file from our own computers (10Mbit
network connection), all is fine and dandy. But when modem users try, or
if we try with extraordinarily large files, we get the following error:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST
/artists/testartist/testtrack/add_mp3.
Reason: Error sending from remote server.
Apache/1.3.9 Server at mp3.no port 80

Well I am not a Zopeguru by far, so the only idea I have is that in the
worst case you can always use ftp to such the stuff out of zope, then edit
it, then push it back into zope with ftp.

Well this is really something ftp should work for; making backups. ;)

NS (4.72) goes up to I guess 40 MB or so in worst case here. Just restart
it every day and it should be fine. Also, RAM is cheap (ok not as cheap as
it used to be a year ago, but anyway), so make sure you have 128 MB of ram
or more in your machine.

Mozilla is way cool, but it's still alpha so use at your own risk. I found
it is almost, but not quite, ready for real use.

Hello, 

we have some strange problems with the "SiteAccess"-Product. We are
building up three web-applications on one Zope-Server and three different
domains. Everything works fine with the "Site-Access" but if you have more
than 5 requests at one of the sites the speed gets very slow and you have
to wait about 3-5 and more seconds to get back a simple dtml-document.

We made some tests with the __no_before_traverse__ in the url and found
that there isn't that speed-problem if we access the documents direct
without use of the virtual-hosting.

Has anybody the same problem or an idea how to solve this ?

Since Zope always tells -at the line CatalogAware.manage_afterAdd- the

CatalogAwareness file. However, I still get this stupid message the object
CatalogAware doesn't exists, etc...

Somebody an idea?

on win2k i used to use InternetExplorer 5 , but it is
incredibly annoying when the backspace-key is also the hotkey for
'back'; i guess you can see what problems might arise
from this when you accidentally unselect the textfieds when
deleting text, and press backspace a couple of times and end
up 3 pages back in history..

I have found Opera 3.6 to be by far the best browser for
zope-management. It is quick, lightweight, and usable with
full keyboard-access, but it costs money, and allegedly the
linux-version stinks (haven't tested it myself)

Hi Petr,

I found the solution to your problem:

Zope here behaves different, depending on if it's running in normal or in
debug mode ("z2.py -D"). The deb package start up Zope in normal operation
mode, while the binary release's start script starts up Zope in debug mode.

When used in debug mode, Zope appearently doesn't cache extensions,
therefore you don't need to tell it that the module has changed. In normal
operation though, it seems to cache them, so that you have to "edit" the
method to tell Zope something has changed.

As I said, I guess it's a performace question and therefore an intended
feature. At least it's no bug in the deb ;-)

Actually, that isn't quite the point.  He isn't actually arguing 
for AOLserver's superiority over every other system, and somewhere
(but I can't find exactly where) he suggests instead:

     Your development technology doesn't matter.

I wish more managers knew this.  You can build interesting
applications in Zope.  You can build them using Java servlets, or CGI,
or WebObjects.  No tool is going to magically solve all your problems,
and solving them will require familiarity with your tools, hard work
and careful effort, no matter what you use.

We had a manager here who was quite enamored of Java, and early on we
wrote some stuff in Java servlets.  He viewed our Zope work as just
stopgaps on the way to Java code that would carry us into the
long-term, but every time I asked "What problem would be solved by
rewriting all our Python code into Java?", there was no clear answer.
Unfortunately, far too many people in business computing follow
a similar management-by-white-paper-and-press-release style.

Similarly, Greenspun argues that you shouldn't re-invent databases; it
would require a tremendous amount of work to add to your home-grown
system all the features that existing databases have -- fancy query
optimization; storage across several devices; on-line backups;
federated operation; etc...  So use an existing system; Greenspun's
preference is Oracle, but he doesn't argue it like a law of nature.

No, you're not wrong; I did have this problem.
Adding /usr/local/lib/python1.5/lib-dynload to LD_LIBRARY_PATH makes
everything behave much more sanely.  :^)  I wasn't able to import
standard python modules (like socket) before, now I can.

And yes, this was a problem with my basic python installation, but
since I'm only using Python to run Zope, I hadn't noticed.

Unfortunately, this doesn't make things better.  :^(  When I run the 'start'
script, I still get the same error:

$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

/opt2/local/zope/Zope-2.1.4-src/lib/python/ExtensionClass.so: symbol
PyImport_ImportModule: referenced symbol not found


Here's the part I don't understand.  I started stepping through z2.py (isn't
open
source wonderful?!), and trying the import commands one by one in a normal
Python interpreter.  They all succeed, including the one on line 436 which
resolves
to "import Zope".  Yet it doesn't work from within the 'start' script.

Oh well.  I just verified that I can set up Apache+FastCGI+Zope on my
Solaris2.6
box just fine with the binary distribution.  Am I correct that I should be
able
to set up FastCGI using a TCP socket that isn't localhost, and therefore be
able
to run Apache on our 2.5.1 box and Zope on a 2.6 box?  This would let me get
started
using Zope while I figure out how to install from source at a little more
leisure.


Thanks for all your help,

Not a stupid question, and not simple, either.  There are two ways to do it,
and choosing one over the other can be difficult.

1. Store the absoulte_url() of the referenced object, and run this through a
dereferencing method whenever you want to grab it.

Advantages:  If you really want a reference to a *location*, as opposed
to a specific object, this is the way to go.  That is, if you might delete
or
move the object, replace it with another one with the same name, and
expect the reference to refer to the new object, do this.

Disadvantages:  If you expect the reference to follow the object around
if it's renamed, don't do this.  It has to climb up the path to the object
instead of just grabbing it directly

2.  Store the object as an attribute of the referencing object.  This has to
be done (I think) from an External Method, since you *aren't* setting a
property.  You do something like "self.fooref = self.path.to.other.aq_base"
which DTML doesn't allow.

Advantages & Disadvantages: The inverse of #1

Architectures like Oracle with Vignette running atop it are very
capital-intensive.  Something that startup dot coms don't have a lot of.

Yes, it's a shame, because this model introduces yet another way where
you have to partition your "cloud".  It shouldn't matter what processor
or network gets added to your website "cloud".  Just keep throwing
capacity into the cloud.

Existing scalability architectures have such a schism along the
three-tier boundaries that it takes wizards to implement and operate
them.  Making them, obviously, brittle and prone to problems.

It will certainly take some time.  But obvious things can be solved as a
higher priority.  Since scalability means different things to different
people, though, there isn't One Answer.

I don't feel that advances in Python are absolutely required.  Apache
doesn't have a threaded model (before v2), and if Zope could dish out
requests like Apache 1.x, everybody would be awfully happy. :^)

This begs the question: how fast is fast enough?  These stupid PCWeek
tests, that give MTS a higher performance score than WebObjects because
it claims to do 4,000 requests/sec vs. 2,000 requests/sec, are just
ridiculous.  At 150 requests/sec, you're talking about the top one
percent of websites on the Web.

The other worry is that these super-freaky Python advances will require
cooperation from the app developers to keep the train on the tracks.

Again, I'm not so sure this is the big answer.  I don't think there's a
lot of evidence that Medusa/ZServer is the primary bottleneck.

Yep, this is ultimately an attractive architecture.  Particularly when
you pour all three tiers (presentation, logic, data) into it, you get a
single facility for scaling and distributing all three.

Right, though I'd encourage you to instead speak in terms of the goal,
rather than the solution.  Is the goal here to solve the 2Gb problem on
Linux/x86, to "limit corruption", or is it to do resource accounting on
a per user basis?  As Jim has pointed out, if your goal is the latter,
you won't get there -- user data can still appear in global things like
catalogs.

Jim's counterproposal, which he claims is easier than doing accounting
across separate Data.fs files, is to finish putting accounting hooks
into the object database.  Whenever a user exceeded their capacity (no
matter where the object), an exception would be raised.  This would
probably require that people be able to do their own packing.

I gotta admit, I'm awfully intrigued by this.  It is the kind of thing
that is _seriously_ compelling vs. other architectures, where you have
to keep on-disk quotas for presentation and logic, and in-RDBMS quotas
for data.

Still, the point is, make sure you speak in terms of goals first.

Doubt it.  There's still so much more, such as data scalability (vs. raw
performance).  As for the latter, we at DC _still_ need to make raw
performance go up.

Personally, I think a very smart caching system (where subtemplates are
pre-rendered in ZServer and know when the objects they depend on have
changed) is a huge win for a significant portion of high-load
situations.

Right.  Does this, though, limit them on the platforms you run on
because of assumptions in the threading model?

Right.  But again, this begs the question: what is a "nice site"?  What
if the goal of a "nice site" could be met w/out the disruption of
rearchitecting Python?

Is a "nice site" 100K hits/day?  A million hits/day?  Ten million
hits/day?

This steps into the next part of the problem.  To date, few in the Zope
community has been willing to publish any numbers for highly-traffic'd
sites, despite pleas even from our board chairman.  Perhaps that means
there aren't really any sites where Zope's limit has been reached?
Probably not.  But why are people so reticent to go on the record with
their hit logs?

But it _does_ mean that, until folks are willing to come forward and
provide numbers and test conditions, that we'll be working without a
map.

Subject: [Zope] Python equivalent of dtml-with?
Message-ID: <4.2.2.20000306100755.00b7bc90@saladin.aisys.com>

I'm writing an external method in Python which is going to be used to 
create new instances of a ZClass that I've written.  In my normal DTML for 
object creation, I would do something like this:

<dtml-with "ZClass.createInObjectManager(REQUEST['id'], REQUEST)">
    <dtml-call 
"propertysheets.instanceProperties.manage_editProperties(REQUEST)">
    <dtml-call unindex_object>
    <dtml-call "manage_editCataloger('MyCatalog', REQUEST)">
    <dtml-call index_object>
</dtml-with>

I've got an external method written which is able to create a new object by 
calling the ZClass.createInObjectManager method.  However, I'm not sure how 
to code up the code contained in the dtml-with block using Python.  I 
suspect that I could get things to work for the example above with 
something like this:

(self is the product containing my ZClass definition)

newobj = self.ZClass.createInObjectManager(REQUEST['id'], REQUEST)
newobj.propertysheets.instanceProperties.manage_editProperties(REQUEST)
newobj.unindex_object()
newobj.manage_editCataloger('MyCatalog', REQUEST)
newobj.index_object()

However, I'm interested in knowing how do code up stuff in Python which 
would take into account acquisition.

Thanks.

(AFAIK, the ObjectManager (base for folder) uses this mechanism too.)

Was just wondering, why the 'aq_base' part is required ? What could go wrong if
I just had self.path.to.other ?

Subject: [Zope] Refactoring Question
Message-ID: <4.2.2.20000306104328.00b75dc0@saladin.aisys.com>

I have a DTML method that I would like to refactor but I'm unsure of the 
results I'll get.  In one of my products, I have a ZClass_add method which 
has code which does something like this:

<dtml-with "ZClass.createInObjectManager(...)">
     <do something>
     <do something else>
     <dtml-call unindex_object>
     <dtml-call "method_editCataloger(...)">
     <dtml-call index_object>
</dtml-with>

What I would like to do is yank all the content out of the <dtml-with> 
block and put it in its own method.  I'm thinking that I would like the 
method to live in my product folder, but I'm open to suggestions.  The end 
result would be something like:

<dtml-with "ZClass.createInObjectManager(...)">
<dtml-call initObject>
</dtml-with>

and the initObject method would be contain

<do something>
<do something else>
<dtml-call unindex_object>
<dtml-call "manage_editCataloger(...)">
<dtml-call index_object>

My first question is, if I create an initObject method in my product 
folder, if I call it from within my dtml-with, will it execute exactly the 
same way as if it were included inline or would it somehow lose the fact 
that it was executing in the context of the "with" object?  I'm thinking 
that the "with" information is put on the namespace and the namespace will 
be available with my initObject method is executed, but I want to confirm 
that my thinking is correct.  Alternatively, should I define my initObject 
as a method of the ZClass itself rather than defining it in the Product folder?

Thanks.

There was a thread on this here about 2 weeks ago titled "object icons".
There is a "deprecated" way of doing it, but the thread got off track
without a real answer (the "right" way). The "deprecated"  (the
old-fashioned) way is documented in the old Product API and is used by
ZScheduler. It works like this:

In __init__.py module:

# use the old method to set the icon for the ZSchedule object
misc_ = { 'ZScheduleIcon': ImageFile('www/ZSchedule.gif', globals()) }

In class definition.

class ZSchedule(ZCatalog.ZCatalog):

I'm trying this on SunOS 5.5.1, and am getting more less the same

I have tried adding both the python dynload directory, and even
the Zope/lib/python directory to LD_LIBRARY_PATH, both of which
are no help.

The error I get is a little different:

File "/new1/misc/Zope-2.1.3-src/lib/python/ZODB/__init__.py",
line 85, in ?
  import sys, ExtensionClass, TimeStamp, cPersistence,

ImportError: No module named ExtensionClass.

As mention somewhere in this thread, this all stems from line 436
in z2.py :)

Any ideas?

Hi,

In the Control Panel, Database, Cache area, what does Target Size
refer to?  Number of pages?  Kilobytes?  What does it mean by
"target"?  What exactly is being cached?  Output from methods?  The
method content themselves?  What is the difference between this and
ZCache?

Thanks,
John

   Strange. Just a check: you wrote '-appConnTimeout 0', aren't you ?
mod_fastcgi is case sensitive (or at least it seems so at the first glance at
the source).

   No, they are only used to report to the webserver. As stated there,
mod_fastcgi doesn't even ask for them.

This is true, he doesn't necessarily argue for the superiority of
AOLserver vs. the world, and that is not what I said either. However, he
strongly advocates for AOLserver, which is fine it is good work. But he
and others who follow have also advocated against extending AOLserver
for tools other than Tcl/ACS. He says, after all, what for?

This is true, but it isn't wrong to want to do your job with a tool you
enjoy. In the event that there are multiple qualifying ways of doing a
job within reasonable means of quality, I think a tool you like and
enjoy would potentially help and enable productivity. There is not
necessarily any magically programming language or tool. However, some
are better than others. Programming well, requires effort and work.

Because something requires effort, even tremendous effort doesn't mean
it isn't worth it. Because something may duplicate features of another
product doesn't mean it isn't worth it. Linux did all of this.
Tremendous work and effort to somewhat duplicate available software. At
some point the efforts which could be perceived as a duplication of
existing software may at some point supplant and exceed the currently
available existing systems. Subsequent versions of many existing
software packages can also fall into this same description of tremendous
effort, to duplicate the features of existing software. But this is
generally for a reason. Some times to improve certain things,
performance, add features, interoperability, portability, etc. I'm sure
Oracle has done this. I'm sure Philip has.

In his forum and other writings Philip has openly argued against most
any potential competing database to Oracle. In his argument he believe
the price of Oracle isn't/shouldn't be a problem. However, to many
people it is. Even though his webserver of choice is db agnostic, his
software ACS isn't. It is very much hardwired to Oracle. Talk to the
people involved in the ACS port to PostgreSQL.

Any advancement of technology will come at a price of tremendous effort
and duplication of current capabilities and features. Sometime it's
worth it, sometimes not.

Philip is right on many of his points. How much has software really
advanced from the capabilities in Lisp from so many years ago? Very
debatable.

As I said his book is a very good read, great material. I like many of
the business ideas and practices of ArsDigita. I have populated my
library with many of his book suggestions.

I have absolutely nothing against Philip, ArsDigita, AOLserver, ACS,
Tcl, etc. AOLserver/ACS is a great tool and toolset. However, in the
discussion of comparing AOLserver/ACS (really ACS) to Zope it basically
boils down not as much to features but to design/architecture of each
tool and scalability. Some people will prefer the ACS way over the very
OO way of Zope, some the opposite. If you are agnostic on such, then
scalability may become an issue. AOLserver/ACS and Zope scale
differently. Philip has a distinct view scalability. Farms, clusters,
no. Single machine, multi-processor, yes. Database == Oracle (his other
uses were also big $$$dollars). Hence scalability == $$$dollars.

AOLserver/ACS currently scales better than Zope. Zope may not currently
be the best choice, or a choice, for Amazon, Ebay, etc. But I think it
can someday. Because Zope is reasonably db agnostic (it does like
transactions), it may be a better solution for many people than ACS
since it is tightly linked to Oracle. If your money and data is
somewhere else you would have to port. In their forum I made comments
that it would be great if ACS were decoupled from it's specific database
dependency. The db connectivity could be abstracted and an appropriate
database api could be created. This would enable other database users to
use ACS. No interest from ArsDigita. Instead there are various peoples
rewriting ACS for their db of choice. As far as I know all hardwired. :(

There is definitely room for both to be successful, and others like
Enhydra. Then there would quality choices for users of various
backgrounds and personal preferences.

There is most definitely a give and take among the choices out there for
languages, webservers, app servers, etc. As for me, when surveying the
landscape from my world view and perspective, the other options
primarily potentially beat Zope "currently" in scalability/performance.
But for me Zope won other areas. I like Zope, I like ZODB. If I don't
have to use an RDBMS, I won't. However, I do hope for ZODB to improve to
the robustness and scalability of the RDBMSes. For some uses it is.

As I read the paper today and see 1 ghz Athlon machines becoming
available, Zope horizons are looking better. Go Moore go. :)

Subject: [Zope] Comparing "unsized objects" and strings
Message-ID: <38C3ED35.C507DF33@newopenness.de>

Hello all,

I have a little problem. I know where it is, but not how to solve it :-)

I have a DTML document:
---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- aid comes from the result of the externalMeth -->
</dtml-in>
---snap

Okay, no problem so far. But when I want to compare the value to a
parameter I have given to the document via a <FORM>:

---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- Okay, works fine of course -->
<dtml-if "aid == param">
Hi there!
</dtml-if>
---snap

The expression evaluates always to false. I have traced the problem back
with an external method ("<dtml-if "equals(aid, param)">"). When trying
the "len" function on both variables, "param" is not a problem (it's a
string from the the <FORM>), but "aid" complains that it was an "unsized
object".

How do I compare them?

Thanks in advance
  Christian

hmm .. untested:

<dtml-if "_.str(aid)==param">

_.str(aid) should return a string presentation of aid.

Woohoo! Absolutely. :)
However, if a multi-threaded/multiprocessor capable Python were
available to embed into AOLserver then it seems to me that the improved
performance would be transparent.

This is true if the requests are evenly amortized throughout the 24 hour
period. Unfortunately they aren't. For me fast enough means that your
machine is not maxed out (or croaking) when handling peak loads. Your
visitors handle the speed/latency well. It is all very relative.

I agree. I was just hypothesizing. I would generally prefer to keep with
the advancements in core Python. Who knows what Py3k will bring. :)

True and maybe not. However as Zope pushes into heavier trafficked
environments who knows. But we'll take whatever speed gains we can. :)

What I like about this is the capability of distributing your work load

Actually not necessarily either. I don't want data corruption, so if
that's an issue it will need to be addressed. Say for example I have a
very large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5gb directory which is reasonably stable
updated monthly.
ZAuto/manufacturers isn't so large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.

My example above doesn't fit into this situation, at least as far as I
can tell. There are no user quotas or explicit restrictions.

I have somewhat lumped raw performance and scalability together. In many
ways they are hard to separate. I agree a smart caching system would be
nice and a tremendous boon to performance. In Philip's writings, he
believes that performance is best when the entire db resides in memory.
Sometimes that is not possible. However, if you cache the most often
accessed parts you reap tremendously.

I don't know, I am not a threading expert. However, with AOLserver, I
believe that stayed with the POSIX model. So if Python was such it seems
it wouldn't be a problem in most cases.

Yes, this is a very subjective area. My original problem with Zope's
scalability and what would scare me with a site is the inability to
throw hardware at it. ZEO didn't exist then. The question exists though
is if a Zope based website was getting 1 millions hits a day and gets
Slashdotted or some other such phenomena and in a few weeks or months
grows to 5 or 10 million, what are their options within Zope? Where will
the bottlenecks come from? Can they throw hardware at it? What if
tomorrow my "Slamazon" bookstore went online and was an instant success?

It does, but the "string" is still an unsized object. 'Scuse me, I
thought Python is not strong-typed?

I'd have thought someone would have answered you by now. Have a look at the
Zope Quick Reference:

  http://www.zope.org/Members/ZQR/

Also, looking over the doc/CHANGES.txt file can give you lots of clues about

I'm very new to zope and I was wondering how I can reference a property that
is in a subfolder.

ex:   there is a folder called "main"
      inside the "main" there is a folder called "sub"  and I create a
property called 	"message"

	is there a way for me to call to that property outside of that folder.

Any help would be greatly appreciated. Thanks

If I am understanding you correctly, you should have a look at Loren
Stafford's ZScheduler. Download it from Zope.org, and look at the code for
the ZEvents. They are catalog aware, and override manage_afterAdd, then call
the superclass method.

Hi,

What versions of Zope (probably 2.1.4) and what versions of MySQL work together?   I have tried unsuccessfully to get MySQL to work with the the MySQLDA using the latest stuff.

 Submitted by:  Dylan Jay djay@innocent.com

 When I create a ZClass with my own management methods they 
 will by default use standard_html_header etc. This doesn't look 
 like the standard management interface. I think we should have 
 a standard way of making all management interfaces look the 
 same.  In fact this should be able to be changed for any subset
 of management interfaces so you could for instance change the
 way the standard zope interfaces look.

Dang!  Another "lead zepplin" topic!

Perhaps everyon was holding off because they expect that the
management interface is merely a short-term, necessary evil, to
be replaced RSN by:

 * The "Zope Studio":http://www.zope.org/Resources/Mozilla/index_html
   project, which uses Mozilla's way cool XUL technology to build
   "Zope-aware" chrome in the browser?

or:

  * The upcoming Model-View-Controller
    "re-archictecture":http://www.zope.org/Resources/Mozilla/ZWiki/ModelViewController 
    project, which works to divorce the HTML presentation (the 
    "view") from the underlying Python objects (the "model");
    this is enabling technology for ZopeStudio, the 
    "ZIE":http://www.zope.org/Members/johanc/ZIE/ZIE-demo cognate
    for InternetExplod^Hrer, a wxPython and XML-RPC client like
    the one Amos Latteier
    "demonstrated":http://www.zope.org/Members/Amos/XML-RPC 

or:

  * The "Portal Toolkit":http://www.zope.org/Products/PTK, which
    replaces much of the current management interface with new
    "wizard"-based configuration tools.

I'll close by thanking Dylan Jay for suggesting the topic, and
for his thoughts on potential solutions.

 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel

Hi everyone,

I'm asking this question again because I still haven't been able to work
it out for myself. I'd like to have a button or link on a page that, when
pressed, presents the user (the Manager actually) with a dialog to upload
a new version of a file object that's in that directory. I presume that
the manage_upload method would do the trick, but I can't figure out how to
use it.

The file object I want to update is called 'Bookmark.htm'. I'm trying to
make it easy for our school librarian to distribute our standard bookmarks
to all of the machines in the building.

ZCache caches method results.  It's kinda broken and not very extendible. 
I'm writing GenericCache as a replacement, but it'll only be finished when I
have enough time.

Subject: [Zope] Listening on specific interfaces
Message-ID: <7502CAC76F59D211B0090000F8662FA305F43EE7@ap3expr3applge.appl.ge.com>

All - After bringing up a logical interface (hme0:4) on physical interface
hme0, Zope will not work if I try to use a value of 80 for the HTTP port.
Netscape Enterprise Server is running on this same box and is already bound
to the physical interface hme0 listening to port 80.  My guess is that Zope
is not really binding to the virtual interface, but is trying to bind to the
physical interface and thus it is conflicting with NES.  The error follows:

$ ./start -a 3.130.232.27 -w 80 -f 8021 -m 8099
Traceback (innermost last):
  File "/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/z2.py", line 493, in ?
    logger_object=lg)
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/http_server
.py", line 552, in __init__
    self.bind ((ip, port))
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/asyncore.py
", line 205, in bind
    return self.socket.bind (addr)
socket.error: (13, 'Permission denied')

3.130.232.27 = hme0:4

If I specify an HTTP port that is not currently bound to the physical
interface (hme0), such as 1234, Zope starts up properly.

How can I force Zope to bind to logical address 3.130.232.27:80 so that it
no longer conflicts with NES?  Is this even possible?  I have a few Zope
apps. that I would like to bind to different logical interfaces on port 80
so that I can use different hostnames.  Additionally, I do not want the
user(s) to specify a port in the URI.

Thanks,
-Brian

LoginManager is a thing that aims to replace user folders.  It accepts
plugin User Sources (which know about users) and Login Methods (plugins
for different methods of logging in -- things like Basic Auth, Cookie
Auth, etc).

You can get it from the ZopePTK CVS. (It's useable without PTK, though
-- there's nothing PTK-specific about it. It's just that it's
particularly useful for PTK)

LoginManager currently comes with a default User Source called Generic
User Source (GUS), that is a GUF-like roll-your-own system.  It uses
GUF-compatible methods (userExists, userRoles, etc), so converting any
GUF-using site to a LM site should be pretty easy.  We plan to write
another User Source that is a simple ZODB-based plugin that parallels the
current plain User Folder.  Other existing User Folders (etcUserFolder,
etc) could/should be converted to user sources. 

One advantage is that you can have more than one user source, so if you
need to have employee logins from your corporate LDAP directory and
customer logins from your Oracle database, you can do that. The
implementations of each can be completely separate and reuseable.

Another advantage is that there is no longer the "n times m" problem of
login methods.  If someone writes a PostGresSQLUserFolder that does SSL
client certificates, there's no easy way for you to use that SSL client
certificate capability with etcUserFolder.  But with LoginManager, if
someone writes a SSL client certificate Login Method and someone else
makes an etcUserSource, they automagically work together.

There are some other cool features too, and more coming.

By the way, for those of you who were at IPC8 and were confused by the
RIPP Patterns talk (which is everyone who attended, I think ;->),
LoginManager is so far a good example of at least the RI part of it.

LoginManager is the Implementor for users (it's just called acl_users
instead of I_User :->). User Sources are really Racks. 

The "things from different authors automatically work together" nature
of LoginManager is exatly what RIPP is for. Now that we have an example,
maybe we can try to explain it better and get other people using it for
other things :-)

Despite your following (very good) points, this is not true.  It leads
to conclusions like "Perl is just as readable as Python", "Let's just
use C, it can be made as portable as Java", "We should use Lisp for
this 3D first-person shooter, we just need a better algorythm than
previous C implementations."

A better way to phrase this is:

	Your development technology is only one piece in a larger
	puzzle.

I've recently switched a rather large project from Java to Python --
throwing out nearly 2 years of work in the process -- and I have
noticed an immediate increase in development speed.  Changing
development technologies was a GREAT idea; but only because it was
considered within the framework of the developers we had, the skills
they had, and the relative advantages of both frameworks.

The project had a high dependence on lists and hashes.  Changing to
python increased performance (all these data-types are native in C, in
python; profiling our code shows that it spends most of its time
inside java.util.Hashtable), scalability (Java has lots of hard limits;
a max of a few thousand interned strings, 32M of RAM per process unless
you start diddling command-line arguments, and GC gets unbelievably
slow if you do that), reliability (the JVM on Linux is buggy; python is
pretty robust if you're not using any crazy native modules ^_^), and
last but not least, we get the source to our tools so we can improve
them ourselves.

Certainly, nothing is a magic bullet or a panacea that will make all
your development problems go away, and I doubt that anyone reading this
list believes that.

Coincidentally, if you are, and you do, I have a GREAT WAY to MAKE
MONEY FAST with NO INVESTMENT!!! It is NOT MLM!! ;-)

This is a great point.  Considering the technology within a coherent
whole is EXTREMELY important, and the view of some managers that
something is just going to be a panacea that resolves everything is
depressing.  It's not limited to development technologies though -- it's
"employee empowerment", it's "diversity training", "thinking out of the
box"... bad management transcends the boundaries of space and time =)

In my experience (I admittedly haven't read this particular article)
Greenspun's advocacy of Oracle and WebDB is near-rabid and biased
toward extremely high-end applications for people with lots and lots of
money.

What you're referring to as "re-invent"ing, by the way, is referred to
by some as 'innovation'.  However, I will agree that the time to do
that is not necessarily when a large project is nearing a deadline...

Finally, I think Zope is a great tool, and for some applications (making
a Slashdot clone, for example) it DOES have the kind of killer advantage
that can make it worthwhile to switch lots of work in another system to.
 It all depends on what's appropriate though -- if, for example, your
site needs to have access to AdaBase, I don't know if Zope is the best
way to go.

I have actually seen projects for which CGIs written in C++ were
unquestionably the best choice.  Examples like that are rare, but they
do exist.

Hi,

I'm running Zope 2.1.14 on Redhat Linux 6.1. I would like it to start 
automatically when the computer boots. I'm looking for a workable rc script for
this configuration.

I tried the script found on the How-to: Installing and Upgrading Zope 2.X.
On start up the computer displays the messages "Sarting Zope2 service: ".
However it doesn't go further and I have to reboot my computer. Thanks in
advance.

Here is the script I used. Thanks in advance.

You didn't say what problems, if any, you are having, so I'm just going to
take a shot in the dark.

By choosing a DTML Document, clicking on the Upload tab, and viewing the
source, I believe you need something like:

<FORM action="manage_upload" method="POST" enctype="multipart/form-data">
<INPUT type="file" name="file" size="25" value=""><BR>
<INPUT type="submit" value="Change">
</FORM>

Make sure you don't leave out the enctype attribute or things will be
unhappy.

Let me know what, specifically, doesn't work if you continue to have
problems. I'll do my best to help.

Out of curiosity, are you running (lauching) Zope as root? The lower ports
(below 1024?) are privelaged on UNIX, and require root permission to bind.
Higher ports, such as 1234, are not; anyone has access to port 1234.

We have a Solaris 2.6 box here running Zope 2.1.4. We launch ZServer with
the -a parameter specifying our interface, and it works like a charm. I
suspect this is not interface related.

Look at the management form that you see when you create a File object, and
do what it does, only in the context of your user interface.

Thanks Jeff...that was the problem...all of my Zope instances until now have
been started by uid zope.  Rather stupid mistake, but a learning experience
nonetheless.

Anywhere inside the "main" folder, you should be able to write <dtml-var
expr="sub.message">.  Outside of "main", you would have to write <dtml-var
expr="main.sub.message"> or possibly <dtml-var
expr="f1.f2.main.sub.message"> if "main" is in "f2" is in "f1".

If I'm understanding the problem correctly, try:

Wade, the best you can do with basic authentication is to do something
like:

<dtml-raise Unauthorized>
 You are logged out.
</dtml-raise>


However, if the clicks cancel on the login box that pops up (there's no
way to prevent it from popping up), he or she will still be logged in.

Use cookie-based authentication if this is a constraint.

You can use the environment variable Z_REALM to change "Zope" to
something else in the login box text.

This looks right.

Acquisition is built into Zope objects; the only time you should ever have
to "take [it] into account" is if you are trying to acquire an object with a
non-identifier Id, or whose Id is stored in a variable.  In these cases
"anobj.aq_acquire('foo.html')" and "anobj.aq_acquire(fooname)" should do.

Yesterday I had to restart NS no fewer than 5 times, to prevent the
'swap-to-death' situation.  I have 96M in my machine, and i've been careful to
eliminate all extraneous tasks to reduce memory usage.

Yes, memory is cheap, but to get this box to 96M (from the original 32) took
quite some wrangling, since it seems ordering more RAM here can have at least
an 8 day lead time, amongst other things.

As a programmer myself (ZOPE is like a holiday :) I know that memory leaks can
be easy to code, and tiresome to track.  But in an application as large as
Netscape, I would hope for slightly tighter quality controls, and a little more
coding discipline.  There are some fairly simple guidelines you can follow to
write "zero resource loss" programs.

Greetings,

I have used MySQL 3.22 (Stable) and 3.23 (Development) with Zope 2.0.1 through
2.1.4.

I am currently using them with the ZMySQLDA version 1.1.3, along with MySQLdb
version 0.2.3.  There is a very good howto on installing these.  I have
recollections of compile problems on my first attempt, but it turned out I was
tryring to compile something that was obivated by MySQLdb.  So, follow the
instructions carefully.

Subject: [Zope] Frequent Zope Restarts and GUF authentication
Message-ID: <m3k8jf4svq.fsf@wacko.pdx.net>

I have a server that is being run in production mode without the
-D flag.  The server processes die after about two hours.  I haven't
seen the actual crash yet nor have any users complained about error
messages.  I know the server is restarting because the Control_Panel
tells me so.

Well, the real problem here is that since my site is protected with
GenericUserFolder in cookie mode, GUF's cache gets wiped when the
server bounces.  This forces my users to log in again.  

Two questions, 
  Any guesses as to what's causing the mysterious restarts?

  Any idea on how to resolve the GUF problem?

Zopists,

Has anyone else noticed that the endmail tag will sometimes not send a
mail even though the dtml method sucessfully completes? It's about one
out of ten at high traffic times, and it happened on Zope.org too when I
tested it by emailing my password to myself a few times.

In this context 'cache' is the in-memory cache of Persistent objects
(most objects in Zope are persistent, for example, just about everything
you can add or manage in Zope is persisent).

Obviously, it's not very good performance to read and write all objects
to and from the database everytime you use them.  Therefore, there is a
cache to speed this up.

The 'target' is the number of objects in the cache.  Note that this is
not a very hard limit, ie, if you set it to 10, it will let you load 10
tiny objects or 10 huge ones.  Or 10 of mixed size.  Experimenting this
this value and watching how much memory Zope consumes is a good exercise
in performance tuning.  Note that there is NO magic value here, you have
to play with it.  Keep in mind that the default is very conservative,
you can definatly start playing with it in the up direction (unless your
running on a 386 with 16MB of RAM...).

I am also trying to get MySQL running with Zope 2.1.4.  I'm trying to follow
the HOWTO by "alanpog."
I got to the part about Expand and Install MySQLDB but I am stuck.  In the
installation README, it says to read Setup.in to verify the paths.  I have
no idea what those paths or for and I don't have them on my Linux system.

Does anyone know what these paths are for and how I can determine what I
should set them to?

I have MySQL 3.22.32, I'm trying to install MySQLdb 0.1.2 and ZMySQLDA 1.1.3
per the alanpog HOWTO

Curtis, what is the really good HOWTO you mentioned?  The one I found is
very brief and isn't helping me much.  Also, where did you get MySQLdb
version 0.2.3?  The latest I saw was 0.1.2.

David, did you manage to get past the Install MySQLdb step?

Thanks,

Eric.

Message-ID: <00030620080400.02221@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

Something that seems maybe very trivial, but I did'nt find the solution.

I have a very simple class ItemId (metatype ItemClass) which is only a
subclass of Image and has no property sheet.

When I try to create a new instance I get the following message : 

Error Type: TypeError
Error Value: argument file was ommitted

Here is my addMethod:

.......
<dtml-with "ItemId.createInObjectManager(REQUEST['id'], REQUEST)">
<dtml-call manage_upload(REQUEST['myimage'])

</dtml-with>
......

Where 'myimage' is the name of a field of type file in my input_addForm.
I works fine when I use manage_upload with an Image but not when it is a ZClass
subclassing an Image. Where am I wrong?

Thanks.

Thanks, that sounds like what I'm after.  I don't quite understand why
this is not setting a property.  Can you point me to some documentation
that might help explain the difference?

I guess putting in a little Python is no big deal, but it does break my
ultimate goal of letting non-technical people create new classes of
content.  Is there any plan to add inter-object relationships to ZClasses?

what about the options in fastcgi?  processes in FastCgiServer defaults to 1. 
-maxProcesses defaults to (50)  >-maxClassProcesses defaults to (10)

will increasing these numbers help stop connection refused error?

fastcgi is a like a black box to me, full of mystery, even after reading the

I hope you got your setup working, Jeff.  Your rewrite rules look
good to me.  But I want to take this opportunity to make a (tested)
alternate suggestion for the rewrite rule.  The above rewrite rule
has the unfortunate feature that URLs like ".../Zopestuff/etc"
match the rewrite rule and get turned into the (not found) path
.../cgi-bin/Zope.cgistuff/etc.  This isn't a problem normally, but
you can perhaps imagine having Zope under a directory with a given
name but wanting another URL with that same name as a prefix
substring to also work (.../news and .../newsimages perhaps?).
I've come up with what I think is a better regexp for use in this
kind of rewrite rule, mostly to avoid the surprise factor of later
having a Zopestuff type URL mysteriously fail to work on me someday:

.../Zope(/.*)?$

which is mapped to

.../cgi-bin/Zope.cgi/$1

The ?$ means that the /<stuff> all the way to the end of the URL is
zero or one time.  So Zope by itself matches, and Zope followed
by a / matches, and Zope followed by /stuff matches, but Zopestuff
does not.

FWIW

If MySQL does everything you need, it is probably the better choice.
GenericUserFolder is more complicated to setup (so it appears better
supported as their are more questions), and exists to support sites
with more unusual requirements.

an acl_users folder only authenticates the sub-tree it is defined in.
If you want AUTHENTICATED_USER available in /home, then move your
acl_users folder into that folder. Your users will not be required
to login if they access stuff that is available to the Anonymous role,
but if they have logged in, AUTHENTICATED_USER will be set.

I'm trying to create a dtml-calendar which searches a Z catalog using

and it seems to work. I seem to be having a few issues with DTML,

</dtml-calendar>
<dtml-var standard_html_footer>

The problem line is <dtml-if "e">. What I was intending to do is
perform the code if the search result actually returned something, but
this doesn't seem to be happening. What I'd like to do is:

<dtml-if "len(e) > 0)">

But, len() doesn't seem to be defined in whichever namespace the code
is being run in. I tried:

<dtml-call "global len">

before the dtml-if, but this errored out as well. Am I completely
misunderstanding the problem which I'm having?

Thanks.

Good luck. :(

 Browsers and servers are neither required to, nor are (to my knowledge)
respecting any sequence of form fields. Basically, IME, if you need the
data going in somewhere to be in the same order ( a program that expects
certain values in certain a order, for example), have whatever processes
the returned data order it for you.

I've just been testing, to see when the most leaking occurrs.  It's definately
whenever I type in the edit box.  At one point I hit enter, and it grew by over
300K.  As I type, I can watch the size grow.  It's really that fast.

As I type, I am downloading the NS RPMs from RH6.2, which seems to be a few
steps ahead of the 6.1 updated i have (From 4.7-1.1 to 4.7-4 .. doesn't look

Much appreciate the effort.

Someone even suggested it might be my Motif lib.  KDE, afaik, catches all the
Motif calls and replaces them with its own widgets.  A workmate running Gnome
checked the same situation, and the memory leaks in just the same way.

scratch another theory.

To use len, try:

  <dtml-if expr="_.len(e) > 0">

It is part of the _ namespace.

You may also be able to achieve the same result (depending on the types of
data involved) using:

  <dtml-if e>

Ok, it appears that len() isn't what I want. I was under the
impression that searchResults() returned an object which functioned as a
list, but this wasn't right, apparently. Or maybe it was, *shrug*. :)
Here's my current code, which I've modified a bit for testing
purposes:

<dtml-var standard_html_header>
<dtml-calendar>
<dtml-call "setCalendar('valign','top')">

      hasdate="hasProperty(d)"                                                              
      dprop="getProperty(d)"

<dtml-if "hasdate==1">                                                                      
  <dtml-var dprop>

This code generates links as it should. What I'm trying to do though
is, if an object of the Event class exists with an event_date which
equals the current rendered date, I'd like to link directly to it. I can
successfully search for the date using the PTK's search form, so I'm
fairly sure that my issues with the catalog are resolved.

So, what exactly is being returned by searchResults, and how can I
determine whether my search yielded anything, so that I can display a
link to the item?

Not if you do not name them explicitly. The REQUEST.form.items() is a
python dictionary. Keys of a dictionary have no fixed order. You could
sort them if you wanted to, but that would be a computer order, not the
original order in which they appeared.

I had a system where it failed (also silently) every first time after reboot.

I just moved to an external method that used /usr/sbin/sendmail as I did 
not have enough time to start debugging. Telnet to port 25 had just a very 
long (>30 sec) startup time, probably some DNS problem. 

AFAIK Zope does not (for some unknown reasons to me) use pythons SMTPlib 
but has rolled their own smtp interface.

It has also been reported to fail with MS Exchange server, which someone 
fixed for himself by swithing to smtplib. IIRC the patches were also posted 
to zope or zope-dev list.

IMHO the right solution for Zope would be swithing to smtplib, and if there 
are faults then fix them there (and maybe include fixed smtplib with Zope 
until fixes are included in mail python distro). There is no need to invent 
to similar but slightly and differently broken wheels, at least in Open 
Source Software there aint.

Message-ID: <4.2.0.58.20000307085505.00c2ee80@195.60.12.162>

Dear Zopers,

I read Chris McDonough's How To on Gaining Zope Enlightenment by Grokking 
Object Orientation. It raised a few questions in my RDBMS-oriented head. So 
I mailed Chris with these questions but Chris explained he just couldn't 
answer them right now and asked me to post them to the list. They seem very 
basic, very fundamental questions to me.

So here is my email to Chris - If I get any answers here I would like to 
include my questions and your answers in a How-To to help those who come 
after me !

Thanks for any help !

Here's the original email

---------------------------------------------------------------------------- 
----------------------------------------------------------

Chris,
I enjoyed your How-To on Gaining Enlightenment very much. I've been using 
Zope for a couple of months now and I've made some progress - my first 
project has been to use it to give access to established databases over an 
Intranet. Like you I think its wonderful, but like you I keep getting 
stuck. Never mind, with the help of the mailing lists and long hours 
reading books on Python etc I've made progress.
BUT ... (there's always a but isn't there) - no matter how much I read and 
play around with OO - I still don't 'get it'. My background is many years 
working with relational databases on Unix - (and there are thousands like me).
I just don't get the bit about storing data as objects. Could we discuss 
this a bit more and perhaps publish my questions and your answers on 
Zope.org ?? This may help me and the thousands like me.
OK, you create your class of Spam, which has attributes of cansize and 
texture and it has methods that display these attributes. No doubt you 
could add other attributes, such as selling price and develop a method to 
increase the price by a percentage. OK so far ?
Now we create an object (which is an instance of the class Spam) - which we 
call myfirstcan. We can define the attributes for that object when we 
create it or later and we can use the methods defined in the Spam class to 
do so. OK so far ?

What I don't get is how you store and retrieve the objects you create. 
Let's go to a more realworld example - how would you implement a stock 
system using objects ? Let's take the simple table Stock which has three 
columns
Product_code Description Price
and we could enter rows of data into it, for example -
ABC Spluggifier 20.00
CDE Super-spluggifier 25.00

Now if I was writing a conventional database system I would maintain the 
above by defining a program which perhaps prompted the user for the 
required columns (Product, Description,Price) and then I would store the 
users input in a row in a table. Perhaps another program (the price change 
program) would use a stored procedure to allow price change. OK ?
Now in OO terms I see that I could create a class of Stock with attributes 
Product, Description and Price. I could create a method to allow price 
changes. Very neat.
Then I can create an object( i.e a particular stock item) by saying 
something like
product_1 = Stock(product_code="ABC", Description="Spluggifier", Price-"20.00")
Now I can create another object by saying
product_2 = etc
but that is not the way you would do it surely. You would be effectively 
'hard-coding' each product in your system.
Surely you would have a program which did something like
WHILE the user is entering data
PROMPT user for data
VALIDATE data
WRITE data to database
END WHILE
How do you do that in OO terms ?
How then do you search and retrieve an object with a particular value of 
product_code ?
How do you write a program which updates the price of all stock items where 
the product_code begins with AB by 2%.?
Thanks for reading this far. Hope you can stop my head spinning !

Regards

Richard

I'm still having difficulty with this.

I want to add a date to a character string ( dated user comments ) to
store into a sqltable.

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">

The docs say that this returns a date string ( as opposed to a date
object? )

<dtml-call "REQUEST.set('mystring', 'date: '+CurrentDate)">

produces this error

Error Type: TypeError
Error Value: illegal argument type for built-in operation

And if I try this

<dtml-call "REQUEST.set('mystring', 'date: '+_.str(CurrentDate))">

mystring is then 'date:'

I have not obviously researched this in detail (perhaps you may want to)
but I do not believe that the any of the various web rfcs define that
either the client or server should send/expect any form elements in any
explict order, and that if any order is mentioned at all it is probably
'implementation defined'.  The introduction of various CGI interface
libraries for various languages probably munges this even further.  I
would not rely on any consistent order at all coming from any system.

We wrote the sendmail tag before smtplib was written.  At the time there
was no existing standard smtp client library in python.

a sequence of record objects that describe cataloged objects that match
your search query.  The are NOT the actual objects themselves, just
'descriptions' that can be used to refer to the objects (with 'getpath'
as you discovered, or 'getobject').

In your case, 

<dtml-if e> 
    There are results.
<dtml-else> 
    There are not results. 
</dtml-in>

I don't undertand what you mean, you code apears to do this.

BTW, it is much easier for other people (or at least me) to assist you
if they can read your code.  For python programmers, this means
indenting it sensibly.

You can do this, but you must be sure you understand that your object
now references the other object without the Zope framework's
'knowledge'.  This is not a bad thing and happens all the time, but you
should be familiar with what this does to things like garbage
collection, persistent object deactivation, and circular references.

I don't know what you were trying to do before, so I can't answer this.

You mean references?  We've thought about this problem a little and Jim
and I discussed this over Chinese buffet once, I obviously had less of a
clue than him, but I belive the result of our discussion is that there
should be some sort of standard for one Zope object to refer to
another.  The simplest way we could think of is simply storing the
path.  Such as:

attribute = "../../relative/path/to/other/object"

or perhaps:

attribute = '/absolute/path/to/object'

Then when you want the object you ask Zope to resolve that path for
you.  Currently you can use REQUEST.resolve_url(attribute) to do that
for you.

If you're not working on python you can simply set a string property as
the path.

This is how ZCatalog does it (actually ZCatalog uses a slightly dumber
version of this concept, don't ask).  HOWEVER, the lack of any kind of
standard or support for such references in the framework has bitten
ZCatalog (and webdav) in the past, and the decisions we made will
probably come back to haunt us real soon now.  You have been warned.

Hi,
Stephen Pitts <smpitts@midsouth.rr.com> posted a patch that may help you.
This patch replaces the socket-base code with smtplib calls.
The original MailHost didn't work with our Exchange 5.5 server, but after I
have applied the patch it works fine.

Hi Zopistas,

A likely FAQ but it's late, I've been Zoping for 15 hours, ZQR 
is temporarily unreachable from Canberra, I can't see straight
and I'll admit it - I'd like to wake up to the answer ...

I simply need to copy an image object (image1) from my
globals folder to within an instance of a containerish 
ZClass.  I toyed with manage_addImage() but couldn't
find a method to get the raw data out of image1. 

Cheers,
Darran.

Subject: [Zope] Tricky usage of string to integer conversion
Message-ID: <000001bf8839$b997a5e0$0b00a8c0@nassau.islands.net>

I am trying to do the following:

<dtml-let x:int="REQUEST.get('prod_config')"
          item="_[REQUEST.get('prod_id')]"
          price="item.price_list[x]">
    <INPUT type="hidden" name="chargetotal" value="<dtml-var price>">
</dtml-let>

The prod_config variable is a number (returned as a string) from a SELECT
list.  The prod_id variable is the id of an object in the same folder as
this method that has a price_list attribute.  price_list is a list of
strings representing prices.

This results in a "Name Error" where Zope cannot find "x".  If I change line
3 to this:

          price="item.price_list['x']">

it fixes the Name Error, but then I get a "Sequence Index must be an
integer" error on price_list['x'].  I would have thought the use of "x:int"
in my <dtml-let> would take care of this issue.  Seems I can't win!

Does anyone know the correct way to do this lookup?

Best Regards,
Brian Holdsworth

"dtml-let" doesn't understand type annotations, so you are setting a
variable called 'x:int', which isn't what you want.  You need to do the
integer conversion in Python, like so:

<dtml-let x="_.int(REQUEST.get('prod_config')" ...>

See the DTML reference guide at zope.org for more useful methods of "_".

I think it must be converted by the atoi method of the string module:

so either:

<dtml-let x="_.string.atoi(REQUEST.get('prod_config'))" 
          [rest of your code]
or:

<dtml-let x="REQUEST.get('prod_config')"
           item="_[REQUEST.get('prod_id')]"
           price="item.price_list[_.string.atoi(x)]">

This is the same problem as last time. You must CALL the Date method, not
just reference it. The above line should read:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date()">

Note the use of parens on Date().

Try it for yourself by putting the following in a DTML Method:

  <dtml-var expr="ZopeTime().Date">

You get:
  
  <method DateTime.Date of DateTime instance at 568eb0>

if you do a View | Source in your browser.

It does, if you CALL it.

Here is some code that works:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
  <dtml-call "REQUEST.set('mystring', 'date: ' + CurrentDate)">
  <dtml-var mystring>

Again, you've never set CurrentDate correctly. View the source of the page
that comes back and you will see the problem.

Hope this helps.

It supports it to no greater or less extent than Linux does.  The
standard library defaults to using an int or a long for *seek calls.
The difference is semantic only, as they're both 32 bits on both
systems anyway.  Even if you assume unsigned (fseek is signed), that's
still 4gb, max.

However, on my Linux/Alpha system, a long is 64 bits.  This
effectively removes the problem.

I submit, therefore, that you are not seeing a Linux problem, but an
x86 problem :-)

Why?  This is overkill for what zope is.  Zope is not, in essence, a
web server.  If you want to do strange things like that, use Apache
:-)

Completely inaccurate.  Proprietary software (Please, use the Jargon
file next time you look something up in the dictionary, geez) is
software which is not licensed under a Free Software license.  This
includes Java *as implemented by Sun* but NOT DTML or Free
implementations of XML.

Well, the issue is not really "the language".  The issue is whatever
software implements it.  Anybody can implement DTML, or Java, or XML,
or whatever, and license it however they want.  The question is,
whether this implementation is Free Software, and indeed, it is.

Interesting point.  I myself prefer Perl to Python for a number of
reasons, but am nonetheless forced to learn some Python to use Zope
:-)

Untrue. Apache's load/stats and Zope's load/stats are different sides of
different coins.

You're implying that Zope has no statistics to export, and that if you
couple Zope with Apache (which you might not want to) then the numbers
that Apache can export would apply to Zope -- and this is clearly wrong.

Thank you for completely sidetracking me and instead choosing a flame
angle for petty word games.

My point specifically was that the mass of mainstream appreciation of
Zope versus a product like Dynamo was specificially _not_ related to
openness. IBM does not open its money floodgates to invest in Linux
merely because Linux is an open technology -- Linux was not the first,
nor the last, not arguably the finest open technology in the history of
IT. It and others do so, and give momentum to Linux, because of money,
pure and simple.

Let me relate a short anecdote for you, about the incident which
triggered this thread. See, my colleagues are currently involved in a
large project for a large company. They are buying Solaris 8 to run
Dynamo. I've made a very strong case for Linux and Zope.

There is, today, only a marginal difference between these two setups,
and that difference is in price: The Linux/Zope combo is significantly
cheaper than the Solaris/Dynamo combo. This has zero bearing upon their
choice, and indeed on most ordinary computer investments for any
company: The cost of buying a computer and licensing the software is
"nothing" compared the maintenance costs and the insurance a big company
needs that their investment is safe. In other words, heavy support plans
and brand names.

And guess what? Despite the fact that both Linux vendors and Digital
Creations offer such support plans, my advice to my colleague and this
company falls dead on the ground.

Zope doesn't have the flashy packaging and sexiness of a product line
Dynamo -- which, actually, I strongly urge you (and everybody else in
this forum) to experience yourself, before you snap back at my again --
and this affects management decisions. Dynamo is exceedingly sexy, and
it boasts the kind of bullshit magic that have management and tech
people alike drooling.

So is it "their problem"? In the end, I don't think so. I think they're
going to be quite happy with Dynamo.

As one of my colleagues pointed out, the problem starts with the name.
(Somebody out there is hyping what they call Linux' next-generating GUI.
And it's called... GNOME. What's wrong with this picture?) I don't care
myself, but I recognize the problem.

I don't claim to be an OO master or a ZOPE master, but I'll give this
a shot anyway and share some recent revelations I have had about OO in
general.

First off, the examples that people always use to demonstrate OO
concepts wind up being more distracting than they are worth.  For
instance modeling a can of spam in OO.  That would be a logical thing
to do, if you were writing a control program for a can of spam.  But
NOT if you were writing a database app!  This, I think is one of the
most confusing parts for database programmers coming to OO.

Second, so if you don't model your can of spam, then what DO you
model?  Well, you model *your data* and if your data is a database,
then that's what you model!  Soo, you create an object of type
"Products_Table" which contains methods to operate on the entire
table.  Then you create objects of types "Products" which contain
methods to operate on the objects.  But since your products can be
many different kinds, you don't "hard code" what kind of product they
are, you just make a generic object that contains generic functions.
If you wind up needing to do something special for a particular
product, *then* you create a subclass of product for that kind of
product that you can use for that.  Ie:  "Delicate_Product" might be a
subclass of "Product" that might have a special some special methods
for dealing with products of that type.  Something like "find" should
be a method of the table that returns an instance of your product.

So, your loop becomes something like this (pseudo code that looks like
c++?):

while(sData = Input.Read())
{
	MyProduct = new Product(sData); // object init's itself
	if(MyProduct.Validate())
	{
		MyProduct.Write(Table);
	}
	delete MyProduct;
}

Is there a way to upload more than one file or image at once?  It seems very
cumbersome.

thank you!

Hmm.. are you sure you are starting Zope as a priviliged user, like root?
Zope can only bind to port 80 if started as a priviliged user (it will not
run as a priviliged user, rather, it will, by default, switch to 'nobody').

The permission denied error is clear pointer in this direction.

Lynx does frames just fine. It lists them as hyperlinks. Just select the
second one, and you'll be amazed how much you can do with Lynx and Zope =)

This is because:

1/ MailHost doesn't integrate into the transaction mechanism all that well
(patches accepted =))

2/ Email is inherintly an unreliabale form of data transport.

Hi. How's Jim getting on with this? Apologies if I missed something

Message-ID: <Pine.SOL.4.10.10003071845510.26849-100000@marlowe.informatik.rwth-aachen.de>

Hi everybody,

although this may have been discussed several times:

I added a multiple property to a class, but when I call the instance's
property sheet from the management interface, I get an Type Error,
whenever I did not chose anything from the selection box. That is of
course ok, because there is no property defined within the instance if I
did not select anything. (getProperty(id) fails on None)
How do I create an "empty selection"?

Thanks for your help

BTW: <dtml-call "REQUEST.set('x','[]')"> did not work.

He has checked in the fix - if you are tracking CVS you need to 
update lib/python/ZODB/TimeStamp.c and rebuild it. For those not
using CVS, I've attached a copy of the updated file to this email 
(but you'll still have to rebuild the extension for the change to 
take effect).

It is definitively not a good idea to rely on browser detection
for you pages. Especially if you dont already know how to do it.
Try to make your HTML-code not so special to let it work for all
browsers (you cant know how to handle the specific of all the
browsers available).
But, if you really cant live without it (please overthing it more
than twice!)
REQUEST['HTTP_USER_AGENT'] is your friend, together with various
string-operations.
Please note: you cant be sure if this field is set and tells you the
truth about the partcular user-agent.

If I have a ZClass with a property sheet called 'Info', how can I get
access to the sheet when I DON'T have an instance of that ZClass to
work with.

Specifically, I want an ADD form for my ZClass that has an ID field
and a dynamically generated section containing all the properties from
'Info' all on ONE from.  I can't seem to figure out how to dynamically
generate the property section without an instance to work with.

Actually the guys at Spam inc. IT do model Spam cans (how about the lot 
numbers in case of botulism or something?) I believe the reference to 
Spam
was just an example though ;-)

More likely I would write a Class called "Table" that knows about 
accessing all 
relational database tables not just "Products" (see Data Adapters in 
Zope)

Would you have a different table for this?  This is a debatable topic -
if you don't have different attributes for your subclass then, it is 
argued,
you don't really need that subclass. Special methods for this can be 
done
as you propose or just tested for in one class.  The reason this is 
important
here (in this discussion) has to do with oo-relational mismatch or 
impedance.
When you are bringing back your objects from the database you are going 
to have
to know which object to "instantiate" (this term is used losely here). 
This means 
special handling for your queries. Or you can pay the pain by having 
two tables which
makes your queries for all objects harder. As you can see it isn't 
necessarily simple.

This would translate to a "Stock" object with three attributes

For me this method would be an instance method, each instance would 
have it called upon itself.

Actually you are correct. There will be an input program. You won't see 
much
difference between OO and your conventional database way (if you will 
allow me
to assign that term here). The reason is we haven't actually done 
anything
too significant yet.

Using my assumptions and examples from above I would have the Stock 
class
ask my table class to build a SQL query to do this

As above have the Stock Class have the table class find all "rows" which
meet this criteria then for each instance send updatePriceBy(2)
where the 2 is an argument and since it is positive the instance of 
stock
will add 2% to its own price

Here comes more spin though I'm afraid (sorry :-P)

Up til now I've left out alot of the mechanics.
The Table Object knows how to form SQL queries which gets you subsets
of your objects (not just rows of data) It in effect provides the code:

   product_1 = Stock(product_code="ABC",Description="Spluggifier", 
Price-"20.00")

only instead of product_1 it would be 'next_row' or 'this_row' 
(depending
on how you like to think of database cursors). Also somewhere there is 
a mapping between
the Table and the Class it represents. This allows the Table to become 
a Class,
the row to become an instance, and the columns to be attributes. These 
mappings
would be plugged into the above code also (i.e. product_code becomes 
attributes[1])

This mapping solution is a common pattern - IDL to Corba, DTD to XML in 
generic terms.
Here we start to see OO work. I defined my class and map it to 
different things
such as Corba or XML - now I can ship the object flattened as a string 
(or some other
form) and a reciever can inflate it back. This would be the user input 
form. This flattening has a special name in ZODB (as far as I can tell) 
it's "pickling"

Hope this doesn't add more head spin. There is much more to this story, 
we haven't
even talked about, such as foreign keys and how to map them to Objects. 
 

As far as modeling the data, I don't model a database, just the data, 
but it also
depends on if you are supporting a previously existing database or 
starting new.  I have done both and it is a black art. You have to 
support management, other departments etc without tipping the boat 
over, so you generally follow the flow. But for the most part you want 
to analyze the problem domain from an object point of view from the 
start. This gives you important insights to other parts of the problem 
such business processes and object interactions you didn't know about. 
OO is not just an elaborate ERD (Entity Relationship Diagram) But it is 
the most common place to start. This is just one way to do it, not 
necessarily the "Right" way, (if there is such a thing)

Hope this Helps

Other people answered your conversion question, I just wanted to point
out that the ':int' notation is meant for use in qualifying HTTP POSTED
data, like that coming from a form.  For example:

<form>
  <input name="bob:int">
</form>

This will cause ZPublisher to try and turn the value of this element
into an integer.  This is the only place the ':int' notation makes any
sense.  In your example, you have confused this notation with that of
the let tag.

Voila.  If you want to see the left hand tree frame go to /manage_menu.

Subject: [Zope] Property Sheet Question
Message-ID: <4.2.2.20000307143411.00b56800@saladin.aisys.com>

I'm defining a property sheet for a new ZClass object.  I want to define a 
property which is collection of items (in my current case it's strings, but 
conceptually it could be something else).  When a new instance is created 
(or edited), I want the user to be able to specify 0 or more items.  Is 
there a property type which supports this?  What, for example, are "lists" 
and "tokens" and how do you make use of them?  In the particular case that 
I'm working on, I want a user to be able to enter one or more e-mail 
addresses and one or more urls.  At some point I will want to iterate over 
the e-mail addresses, or iterate over the urls when I construct a view for 
this object.

Any tips or insights on this subject would be appreciated.

Thanks.

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

References: <m31z5mmy4y.fsf@wacko.pdx.net>
Message-ID: <38C55EE7.36417628@digicool.com>

There is no standard rythem for manipulating the class without an
instance.  At least not that I know of.  It can be done, however,
because it can be done from the managment interface.  Anything that you
can do with clicks in a browser you can do with DTML, it's just in this
case your problem is necessarily complex because we never, ever,
considered your use case when we engineered ZClasses.  This is one of
the reasons why software can be dificult to use, because the engineers
did not KNOW in advance how you wanted to use it.

But you want to do this so I suggest you look at how the managment
interface traverses through the Control Panel and Products to manipulate
ZClasses. Using URL introspection, you should be able to deduce how to
do this.  I would help you but I honestly don't know how it would be
done myself.

I use IE5 on Win98 and NS4.7 on an old LinuxPPC box. No problems here with
Netscape running away though, I leave it running days at a time.

Netscape on NT/98 frequently runs into authentication problems with our Zope
install (using mod_proxy and ZServer) and sits there flickering the status
bar forever, whereas IE5 doesn't do that, it pops up the password dialog
when confused. IE does occasionally crash in the management screens (never
any other time), and I can't figure out why.

Message-ID: <38C56A34.F9D9453B@globalcrossing.com>

Now I am desperate, this is the fourth posting and still only one reply.
Any thoughts no
matter how far fetched would be overwhelmingly appreciated.

Does anyone know how to export an object (Folder or such) from outside
of the Folder that contains the item to be exported without hard coding
the path. In other words I would like to be able to have a user
interface which would allow a person, with an export role, to be able to
enter a
list of fully qualified Items to be exported.

Consider:

FolderA
        FolderB
                ItemToExport

I can export ItemToExport from FolderA by calling:

<dtml-with "FolderA.FolderB">
        <dtml-call "manage_exportObject(id='ItemToExport')">
</dtml-with>




but I don't want the FolderA.FolderB to be hard coded. I would like it
to be a var that I pass into the method. Something like:

<dtml-with FullPath>

what should the syntax be. 

Thanks,

OK, but see you're trying to make Linux something it is not.  Linux is
not about marketing.  It is not about world domination.  We
specifically do not care about this :-)  Now, digicool is a company,
and they probably DO care about this.  Making Zope Free Software is a
great way for them -- and us -- to benefit.  So your comments should
be addressed at them if you want them to make the sale.  Not me, a
Linux hacker.

But see again, Free Software is not about marketing.  The name is
irrelevant to us.  Free Software is about what's *right* and what
*works*.  We leave the marketing to those that want to do it (such as
digital creations, or whomever else).  So again, write to digital
creations' marketing dept. :-)

object?  and then manipulate it in the way you need?  I'm having this same
concern from a project right now -- they are scared to put content in ZOPE
because if we move to another content manager- we may not be able to get the
data out (please point me to info). 

your secondary question is just as valid:  versioning lingo in zope is not
versioning as in source versioning but a 'temporary lock' on files.  things
look differently in/outside of versions.  thats versioning now.  how about
retaining 'versions' of a website (I think vignette does this) - so I can
call (if I had diskspace and *WANTED* to) my website and say, "what did the
frontpage look like last month?, last week?, two days ago?" <- anyone worked
with this, because this is what is typically referred to as 'versioning' (I
believe).

Then again, Windows crashes occasioanlly without you ever knowing why, so

Thirded. I discussed starting somekind of Zope-XML SIG with Amos Latteier
and generally he's favorable to this, but how do we start? We need a mailing

Thanks.

What had me confused is that

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
<dtml-var Currentdate>

and

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">
<dtml-var Currentdate>

both display the same date string whereas I guess the latter should
display an error.  It only reports an error when I try to do something
else with the variable.

Hm, skilled developers do hack on Python! There's the Python people at
CRNI, there's Christian Tismer in Germany doing Stackless Python (which
offers interesting arcane features and a mild performance improvements),
there's the whole JPython group, there's John Skaller with his Vyper
project (a Python interpreter/compiler in Ocaml, one of the reasons
is more speed). Then there's the Python Types-SIG, which I urge you to
look at if you haven't already.

It is _less_ of a problem, but most Pythoneers are indeed interested in
speeding of the language. I haven't heard of zealots who want to hold
back speedups, as long as it doesn't do away with the power.

It'll be pretty difficult to make a beast like Zope exploit type-hints, though,
I think. By the way, the Types-SIG is working on type extensions to Python,
partially for performance (OPT), partially for better error checking (ERR)
and partially for better documentation (DOC). See:

http://www.python.org/sigs/types-sig/

And also see the new compiler SIG:

Type inference is not a simple thing to add to the language, though..

That's of course true. I heard Christian Tismer talk about making a 
register machine interpreter for Python, which could potentially speed
things up quite a bit. I shall ask him about this idea again sometime. :)

All true. Anyway, the only thing you're wrong about is that Pythoneers aren't
interested in improving performance. They are, but I grant you they're not
performance nuts like users of C or C++. :)

Ask Linus Torvalds. :) Anyway, Linux is what people do with it. Not what

I care about making Zope more popular, as there will be more Zope users,
more Zope hackers, and better free Zope support. More cool Zope goodies.
More Zope related jobs. I care about Zope marketing.

Even if you only care about Free software, you care about marketing it,
as you care about what's 'right', and therefore you want people to use
the right stuff; Free software. Right? :)

Alexander Staubo obviously was interested in Zope marketing. Why tell him
'we' don't do that, while some of us are definitely interested?
Free software is about people doing what they want. Let us do want they
want and don't speak for me. :) Thanks.

This is just a guess (I'm a Zope newbie too) but I believe

<dtml-return "['John\'s', 'Mary\'s']">

Will work.

In the second case, I guess <dtml-var CurrentDate> is recognizing that
CurrentDate is a reference to a function and calling it.

I understand, now, how that had you confused. Anyway, glad it's working!

These are what you want. In the case of tokens, it will separate each word
into a list element. A "lines" property separates each line into a list
element.

Tokens: 'foo bar baz' = ['foo', 'bar', 'baz']
Lines:
foo bar
bar
baz

Becomes: ['foo bar', 'bar', 'baz']

This should work fine using standard <dtml-in>s, since tokens and lines are
sequences.

The kernel internals of Linux use a 32 bit off_t, hence discussion of
large file support in the next kernel release.

I'm not seeing an x86 problem at all:

lukasiewicz$ uname -sp
NetBSD i386
lukasiewicz$ ls -l huge
-rw-r--r--  1 tsarna  users  17592186044415 Mar  7 12:41 huge

Granted, that's a sparse file (I can't afford that much disk space :^),
but it demonstrates that file offsets are not a problem.  As mentioned,
NetBSD's off_t has been a 64 bit type for about 6 years now, even on
i386 (and evey other platform).  In fact, off_t was made 64 bit in 1994,
and NetBSD/alpha didn't exist until 1995, so it was done before there
were any native 64 bit platforms supported.  :-)

However, it turns out that for Zope use, at least with FileStorage,
there is a problem, which turns out to be even an x86 issue but a silly
ANSI C spec issue.  Unfortunaly Python large file support is broken on
(32-bit CPU) NetBSD as a result -- I had to make that sparse file with a
little C program.  Now, you could have a more than 4G BerkeleyStorage
Zope system, since the file handling isn't done at the Python level in
that case, but FileStorage won't work until I can work around the Python
problem (or until NetBSD 1.5, which will fix it in a different way). 

But at least it's the kind of thing that could be hacked around in an
application by one guy in a day, rather than taking drastic kernel
and libc changes :-)

What version of Zope is this?  A recent bug fix has been checked into
the pack function and my line numbers don't corespond with yours.  I
need to know what version of Zope you are using so that I can get the
right version of this file.

Packing does not modify your existing database file until it completely
succeeds.  During the pack, packed data is written to a temporary file
and your main file is just read from.

FYI, you are searching for the union of two search terms, 'ZODB' and
'troubleshooting' which is why you got more for the second query than
for the first.  To explicitly get an intersection, say 'ZODB AND
troubleshooting'.

That bring you back a much smaller number (0).

What version of Zope is this?  A recent bug fix has been checked into
the pack function and my line numbers don't corespond with yours.  I
need to know what version of Zope you are using so that I can get the
right version of this file.

Packing does not modify your existing database file until it completely
succeeds.  During the pack, packed data is written to a temporary file
and your main file is just read from.

FYI, you are searching for the union of two search terms, 'ZODB' and
'troubleshooting' which is why you got more for the second query than
for the first.  To explicitly get an intersection, say 'ZODB AND
troubleshooting'.

That bring you back a much smaller number (0).

One place to start might be to join the Python XML SIG. It has a high
S/N and most of the discussion is probably relevant to the Zope XML
effort.

It would provide the benefit of knowing what's currently available from
AMK, Four Thought, etc., which might be reusable for Zope.

Four Thought's 4DOM, 4XSLT, 4XPath are getting pretty mature, with 4ODS
and 4XLink in the wings.

Additionally, if you haven't the bandwidth (I certainly don't) to
follow the xml-dev newsgroup, the XML SIG gives you a filtered view of
all the mighty standards power struggles going on as we speak in the XML
world, so you can have some perspective on the right time to jump on the
Schema train and so forth.

Thanks.
We will eventually be looking into optimisations for the list command,
to
reduce the depth of braches traversed. If any UW IMAP users can confirm
which flags represent what in that context, that would be helpful. Then
we
could avoid listing them.

Yes, I did get the following response from Drew:

--- snip ---

The easiest way to make changes to all of your SQL methods would be to
export your entire Data.fs into XML format -- then use your magic       
text editing software tools.

With respect to version control and configuration management, I have
used the same XML export format and checked this into CVS. Of course,         
I feel that XML is human readable... YMMV.

--- snip ---

I agree with this basically, and I can see this as a partial
solution.  Basically, if you were using this in production, you would
want to schedule a script to automatically pull out the XML export
from your site say, once a day, and check it into CVS.  Depending on
your needs and your ambition, you could probably go so far as to go
into particular folders and pull out peices of the site individually
and check those in seperately, that way you could look at "Show me all
objects that have changed since April 10th" or whatever via CVS.  This
would also allow you to rollback to a previous version (ala Software
Configuration Management type stuff) by checking out all peices to a
system from CVS and then importing them back into Zope.  Kinda a
hassle compared to how CVS automates other development environments,
but then, other development environments aren't quite web RADs
either.  At least you CAN export and import the data as XML.  A
similar situation arises with tools like Delphi etc where your forms
are binary files and you can't make global changes to them except via
point and drool^H^H^H^H^Hclick.

Note: I refer to scripting exporting.  At this time, there's no tool I
know of to do this.  You would need to do this yourself.  SO... if
there's anyone out there who is a wiz with the ZODB that could MAKE a
tool to pull this stuff out.  I'd appreciate it.  If it was me, I'd
just script something to pull it through the web interface, but a
non-web oriented, just run on the ZODB tool would be better.

Message-ID: <200003080133.UAA14797@saltmine.radix.net>

Ok, I've gotten pretty far with Zope this time.  But (of course), I've
got a bunch of questions.  Starting with...

1)  What is the algorithm for determining which method to call?  The
    DTML documentation says

  "attributes, including inherited and
   acquired attributes, of the client passed 
   in the call to the document template are searched"

   But in what order?   There can be an index_html in the class, in a parent
   class, or somewhere up the acquisition tree.  Which takes precedence?
   Does the product that a ZClass have anything to do with the search?
   What about Z-Super-Classes?  Inquiring minds want to know.

1a) Why can't I have a method in a ZClass, but then override it in
   the instance?  I.E. (Gaak, it has been a while since I've had to
   even think about C++) virtual methods?  (Or have I got that wrong).

2) It seems that the examples require the user to generate forms by
   hand, which seems unnecessary.  For example, (after a protracted
   struggle with the underlying python code) I wrote a method that would
   create an html table for any query, ripping the column names and data
   out of the result object.

   2.1) Shouldn't this be a standard part of Zope?
   2.2) If so, do you want this code?
   2.2) Likewise for property edit forms.  I did find some DTML that
        would do this, but shouldn't this be standard.

3) Anyone want to help me whip snmpy into shape and create soem
   nice Zope classes for accessing SNMP variables and tables in routers
   and such?  

Enough for now...

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time.  I get the following log

I would have to research this to give a precise answer. Basically, it all
depends on the current contents of the namespace stack. Generally, this
will search REQUEST first. Next, we look to the object containing the
method being rendered. Then, the object containing that object, etc.
Whenever a ZClass is queried for an attribute and doesn't have it, it
looks to its parent(s).

I made this mistake when first working with ZClasses, too. If you think
about it a little, you'll realize that, virtual or not, you cannot
customize an OBJECT in C++, only a CLASS. i.e.:

---
class A
{
public:
  int x;

public:
  A() { x = 0; }
};

class B : public A
{
public:
  int y;

public:
  B() { y = 0; }
};

A* objectA = new A();
B* objectB = new B();

objectA->x = 1; // Valid
objectB->y = 2; // Valid
objectA->y = 2; // Invalid, because class A has no such attribute.
objectB->z = 3; // Invalid, because class B has no such attribute.
---

If you want to customize an object (instance), you have to extend its
class, first.

In Python, this is not (really) true. Any old object is a dictionary, so
yuo can add attributes to it on the fly. Thus, the question, how can we do
this with ZClasses?

I wrote a base class that overloads ObjectManager's _checkId method to
allow instances of a ZClass to be customized. It looks like this:

---
from OFS.ObjectManager import bad_id

class Overridable:
    def _checkId(self, id, allow_dup = 0):
        if not id:
            raise 'Bad Request', 'No id was specified'

        if bad_id(id) != -1:
            raise 'Bad Request', (
                'The id %s contains characters illegal in URLs' % id)

        if id[0] == '_':
            raise 'Bad Request', (
                'The id %s is invalid - it begins with an underscore' %
id)

        if not allow_dup:
            if hasattr(self, 'aq_base'):
                self = self.aq_base
            if self.__dict__.has_key(id):
                raise 'Bad Request', (
                    'The id %s is invalid - it is already in use' % id)
---

This is not foolproof (it allows you to override TOO much, i.e. you can
create a method with the same name as a property), but it shows the idea.
I just subclass my ZClasses from this class, and I can customize each
instance individually.

[snip]

Hope this helps. Gotta run.

I am now able to use the GUF the way I want to. I changed the POSTing
destination to something other than docLoginSuccess(docLoginSuccessURL,
the original variable that was there, didn't work at all). I created a
dummy dtml doc called dud, pointed my POST to it, and I authenticated
successfully. Now my problem is is, once I've authenticated like that
superuser can't access that stuff until I restart Netscape. But I think
I can live with that a little better. :)

Thanks a lot Ty for the detailed reply. Mostly for clarifying a few of
the stuff you were talking about at IPC. Seems to me that at least some of
the major components of Zope should be designed in this manner, but on the
other hand it is only after one codes a few specific situations that the
general pattern emerges.

Subject: [Zope] index_html for root
Message-ID: <001201bf88c0$8ad24e40$770da8c0@bbs>

The attached file is intended to replace the current architecture of header
body footer of current zope default index_html.

Together there will be some attributes which can be used to modify its
behaviors :

wap - when defined, set the content-type in RESPONSE accordingly according
to Ducan's WAP howto. and sent out the <wml></wml> tag.

xml - when defined, set the content-type to xml/plaintext and the xml header

frame - when defined, prevent sent out the body tag

Only one of the above can be set. I still got problem with acquisition: if
one of these is set in a higher lever, then all lowerlevel see it. Are there
any easy way to set them off?

doctype - when defined, should contain the correct doctype string: currently
the following doctype is available:

    html4.0
    htmlstrict4.0
    htmltransistional4.0
    htmlstrict4.01
    htmltransitional4.01
    htmlframe4.0
    htmlframe4.01
    xml1.0
    xhtml1.0

The following is defined inside the index_html:

dtml-head - the content of the <head></head> section
dtml-headers - the content of contructs before the main body: This should
not left any tag open.
dtml-footers - the closing contents of the main body. There should not
assume any opening tags.

index_htm - the main content. a frameset statement if frame is defined. If
the main content contains a table, then the main table is defined here, the
parts in the table can then be dtml-var. A index1 index2   .... or indexr1c1
index r1c2 .... naming convention is suggested.

I strongly suggest convert the current zope sites to adapt to this style
through much works shall be needed.

Further work would be in the dtm-head: Recently I will suggest to adapt the
W3C core styles : http://www.w3.org/StyleSheets/Core/Overview

All suggestion and comments are welcome.

Message-ID: <NDBBLBELNHAPHBBCOIFDGEHLCBAA.ewalstad@energywright.com>

Hi David and the rest of the group,

Can you believe I am still battling this MySQLDA installation!?  ARGH!

I hope you can help me out here:

According to the HOWTO by alanpog, I've
1. Downloaded MySQLDA 1.1.3
2. Expanded it into my top level Zope Directory (/usr/local/Zope) Note that
I did not do any installation here, just expanded it into this directory.
3. Downloaded MySQLdb v0.1.2
4. Expanded MySQLdb into /usr/local/Zope/lib/python/Products
4a. Modified the Setup.in file so that the one uncommented line is:
    _mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt
    As you mentioned, these point to where my MySQL libraries are.
4b. According to the README file, ran 'python build.py'
This is where I am stuck.  The build.py script crunches along then bombs
with the following error:

Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I checked and this file is in my /usr/local/lib/mysql directory.  It is a
link to libmysqlclient.so.6.0.0.  Both files are there; owner=root,
group=root.

I'm hoping this is a simple fix ;^)

Any idea's would be greatly appreciated!

Eric.

just it was in the product folder.

I deleted the SiteAccess Product directory and I was able to get in again.

>Is there a HOW-TO or other documentation that shows how to set up a login
>page so that you can use AUTHENTICATED_USER.getUserName()?  Thanks in
>advance for any help/pointers provided.

I don't know if there is a how-to but the way I do this is very
simple. I have a simple form with only a submit button with name login
(it appears on a sidebar of the web site).  When it is clicked it
posts to the current URL.

<dtml-if isRegistered>
You are 
<dtml-in "AUTHENTICATED_USER.getRoles()">
<dtml-var sequence-item> 
</dtml-in>
<b><dtml-var "AUTHENTICATED_USER.getUserName()"></b>
<dtml-else>
<FORM ACTION="<dtml-var baseURL>" METHOD="POST">
<INPUT NAME="logon" TYPE="SUBMIT" VALUE="Logon">
</form>
</dtml-if>

In the start of every page I call a method to check for 'login' in the
REQUEST variable. If it exists I calls or references an empty method
which anonymous users have no rights to but which authenticated users
do have access to (with ID login in this example.

<dtml-if "REQUEST.has_key('logon')"><dtml-var logon></dtml-if>
<dtml-call "REQUEST.set('isRegistered',AUTHENTICATED_USER.has_role(['Staff','Student','Manager']))">

Zope will therefore invoke the authentication mechanism which means
the browser will ask for a login a password as usual. From there on
the user will have been authenticated and you can check their name and
what role(s) they have in the current context. 

As you can see once with the code given here the user has logged in
instead of a login button they will see a message giving their
username and global role(s).

Hope this helps.

Message-ID: <003b01bf88d6$cd7c0860$770da8c0@bbs>

I am making a new head zope index_html file, I think it is now about time to
make use of the HTTP_ACCEPT_LANGUAGE which is sent by the browser to
indicate the perferred language.

The variable is a string like:

lang1, lang2;q=p1,lang3;q=p2....

while lang1, lang2, lang3 is the perferenced languages.

I have think of the following ways to make such brenches in zope:

1. by setting the lang variable in the REQUEST
2. by transfer to the brench of lang/
3. brench calls of index_lang

What will be the perferred way to make such a brench? I want to hear from
all.

In building the brench code : I have come up with the code:

<dtml-in "_.string.split(HTTP_ACCEPT_LANGUAGE, ',')">
   .....do thing according to sequence-item
</dtml-in>

but on the second argument, the sequence-item may contain ;q=0.5 which need
to be trancated. How can I trancated that in dtml?

It's quite nice being able to edit the site using Lynx,
but you cannot create new objects as the 'Add' option
box uses Javascript. Because it's listed as DISABLED,
Lynx won't let you pick a type before clicking on Add.

Just wondering if anyone had written a nice recursive tag converter

move to the new style <dtml- from <--# tags.

I'm also waiting for someone to write the "dtml-method beautifier".  :)
Thanks in advance for any tips/pointers/source.

I played around with nedit's syntax-hiliting so it recognizes dtml as
opposed to regular html.  Not perfect, but better than nothing.  Plus I
improved the python mode a bit.  If any one wants it email me.

Nope.  There may be some standard python library module that I don't
know about, however.  Otherwise, you will have to write your own.

The first two follow standard python rules, first instance attributes,
then shared instance (class) attributes, then any base class
attributes.  THEN acquisition.

No.

Same rules.  First the instance of the ZClass attributes, then shared
instance (ZClass) attributes, then any base (Z)Class attributes.  THEN
Acquisition.

I think your confused but I'm not sure.  If your ZClass is a container
(subclasses ObjectManager) then instances of that class can contain
sub-objects (attributes) with names that are managable by the Zope
managment interface.  The managment interface will NOT however let you
create a sub-object in that container that conflicts with the name of an
existing attribute *including shared instance attributes like methods of
YOUR ZClass*.  Methods of a ZClass may look like sub-objects in a
container instance, but that are not, they are shared attributes of a
class, and all instances of that class will share those attributes. 
Now, this is a limitation/feature of the managment interface, it is not
a limitation of python.  If you want to assign an attribute to an
instance in python that has the same name as a shared instance
attribute, then that instance attribute will override the shared
instance attribute.

Ok.  You're talking about SQL Methods?

If you're talking about SQL Methods or other objects that implement the
Zope Search Inteface then it is allready a standard part of Zope.

You should look at what is there first and tell us how to improve it.

The managment interface obviously builds the property view dynamicly, so
something like this is in Zope.  Whether or not it is useful to others
is unknown to me.

Can I retrieve the author's name from Zope? Is it always available?

I am writing a module to put into the header to generate dublin core rdf

BTW, does anybody have "open source"  legal notices and privacy policies (a
few samples for web masters to choose) can freely distributable with zope?

Right, this is certainly a good place to go to as well. But Zope has its
own rather different requirements, and I think we need a seperate place
to discuss adapting all these technologies so they'll work with Zope -- 
the people in the Python XML-SIG might not care about Zope.

Also, the Zope XML list should also be the place where people ask *questions*
on using Zope with XML; this way we learn more about what people want and
what problems they may be having. And that way we can improve Zope's 
XML support. The Python XML-SIG wouldn't be the right place for that.

Okay, I was considering joining that SIG anyway, but I don't think it's
enough for developing Zope's XML support.

I would say that I specifically do care about this. As a freelance 
developer I want there to be good recognition of Zope in the market place. 
It is all about recognition. I was extolling the virtues of Zope to the IT 
Director at a client and he said 'So why haven't I heard of Zope ?'. My 
answer, that it was all very new and on the verge of success probably did 
not convince him. (Of course it is all very new and it is on the verge of 
success ).

If I say Linux, Perl or C then management are usually quite happy. These 
are recognised names - but nobody owns them. SO it is possible for free 
software to be successful in the sense that they are as well recognised as 
commercial products (which have huge budgets behind them).

Some management (perhaps most) will prefer to buy a "fully supported" 
product from a major player. We don't need to take on that kind of 
marketing head on. Rather we can present Zope and Python as tools to do a 
job, not strategic decisions to be made by management. However it is 
reasonable for management to ask "Will Zope be around in three years" - 
"can we de-Zope if we have to" - "Who owns Zope" "Who uses Zope". Managers 
are not likely to take a "risk" on a product. At the moment they usually 
feel happy that Linux, C and Perl are going to be around in three years time.

If Zope is to succeed it will be because of its capabilities as a product - 
because it installs out of the box in six minutes, while the Microsoft 
equivalent takes 5 hours. Because 60 minutes after downloading it you can 
be running a web page which interrogates your legacy databases (which is 
what happened to me).

We know about the documentation issue, which is hopefully being sorted.

I feel there is also an issue with the product itself. Zope seems to work 
on two levels - you have a very high-level part - I'm thinking of the 
security model, the SQL methods and the Z Search interface, the drop-in 
products like SquishDot etc. These set Zope apart from other technologies 
which people might use (PHP/ASP etc).

You also have a low-level  part (External methods etc). Because Zope has 
the high level part it encourages the thought that there is not much 
'programming' needed to develop a Zope site. But sooner or later you are 
going to hit a wall - for example questions you see asked on this list such 
as "how do I assign a value to a variable". Well the answer is ...

<dtml-call expr="REQUEST.set('abc_search', strip_abc(abc_text))">

... a string of gobbledygook. (So what does the dtml-let tag do is the 
obvious question that springs to mind.)

It is great that Zope has the low level stuff but I feel that work needs to 
be done

1) To analyse actual usage of Zope to see what features are being used and 
which areas of usage cause concern/difficulty
2) To Implement high level dtml tags to implement them.

I've stuck my neck out here - feel free to chop it off.

I have installed ZOracleDA to bridge Zope and Oracle 8.0.5 on Linux.
How do I call the stored procedures written in Oracle from
"Add a SQL Method" interface, especially when there are OUT parameters
returned from stored procedures? I have read the DCOracle mini how-to
but there seems to be a missing step ahead.

Assume the scenario:

Oracle Procedure: myProc(para1 IN  VARCHAR2,

What should I put in the "Arguments" box and "Query template" box? 
And how do I retrieve the returned arguments in the following dtml

Yes, I care too. And for the exact same reasons. The more popular Zope becomes,

Yes. Alexander has brought up a very (IMO) relevant issue. It is in the
interest of the entire community to make Zope well known and I feel marketing
should not be left just for DC to take care of.

I see a number of articles/sites about 'app servers' which don't mention Zope
but mention others (including some mickey mouse servers I've never heard of).
Eg: http://serverwatch.internet.com/appservers.html
Why? Maybe Zope isn't talked about at all outside some circles?

Altavista shows about 1058 pages linking to zope.org (compare php.net:12,000 ;
apache.org:60,000). Why?

If nobody does anything, this will take time to change. If we want this to
change faster, all of us have to actively market Zope. This involves talking
about in appropriate newsgrousps, putting up zope webpages,
making Zope easier to learn and use, adding flashy features etc.
All this can make a whole lot of difference.

Still it would be sensible to do it by splitting the database file (say at
1M boundaries rather than supporting some obscure non-standard system calls 
that only few platforms support. Probably also one-day hack by someone 
who knows where to start digging.

At least this is how it was solved for PostgreSQL .

Message-ID: <001001bf88f9$4b84eca0$a1ac8ec6@hikari.anu.edu.au>

Say one has an object reference and knows the
string id of a child node.  From this info, we
want an object reference to the named child.

I'd like someone to prove me wrong that there
is not a one-liner to accomplish this seemingly
trivial task.  I've had to resort to (off the
top of my head) code like:

<dtml-in "objectValues(['child meta-type'])">
   <dtml-with sequence-item>
      <dtml-if "id == desired_id">
          <dtml-call "REQUEST.set('desired_ref',_['sequence-item'])">
      </dtml-if>
   </dtml-with>
</dtml-in>

I'm really looking for a solution that doesn't
require looping.  Since Zope enforces unique id's
at a given level, the name should be sufficient
to resolve the child object.

Darran.

   I wouldn't buy your idea of easy splitting Data.fs. Exactly like with
the VACUUM, packing Data.fs would be complex task if the data will be

The claim of "a days hacking" was meant as an ironic counterclaim to it being 
a day's job on *BSD

I would suggest it by implementing a file-like HugeSplitFile class and 
using that to hide all the splitting from all other layers. 

If we could implement it in python then it would be perhaps a 1-hour job, 
leaving the rest of the day for fixing up the parts of zope interfacing 
with it ;)

It would probably consist mostly of adding long() to some initialisation 
functions.

   This is a record object. You should use:

On the other hand, if you tell the user up front that HTML tags are not
allowed, you can simply html_quote the text.  That will prevent any tags
from rendering, and prevent normal uses of '<>&' characters from breaking
anything.

Subject: [Zope] Performance and Concurrency
Message-ID: <200003081355.IAA06034@saltmine.radix.net>

I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute).

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

Or, use something like w3m

to take the html and turn it into plaintext.
Pop it into an external method something like the following, and it should
do the trick:

---html2msg.py

from popen2 import popen2
def html2msg(htmlstring):
  try:

    (r, w) = popen2('/usr/local/bin/w3m -dump -S -cols 70 -T "text/html"')
 
    w.write(htmlstring)
    w.close()
  
    s = r.read()
    r.close()

    return s
    
  except:
  
    return 'Error converting article to plaintext.'

---

It's an ugly hack, and you lose things like <br> and <p>, so you may want to
replace \n with <br> afterwards. It does, however, do a brilliant job
layout-wise: tables and lists remain fairly well formatted, for example.

Sorry, I wasn't clear.  What I was looking for was a method to get,
for example, an html table out of what an ZSQL method returns.  I
had to look at the code under lib/python/Shared/DC/ZRDB to figure
out that calling a ZSQL Method returns a Results object, and then
look at the results object to see that it has methods like names(),
data_dictionary() and tuples().  Then I could write a loop like...

    <dtml-with "Your-query-method(parameter=value, parameter=value)">
    <table border=1>
      <tr>
        <dtml-in "names()">
          <th><dtml-var sequence-item capitalize spacify></th>
        </dtml-in>
      </tr>
      <dtml-in "tuples()">
      <tr>
        <dtml-in sequence-item>
    	<td><dtml-var sequence-item></td>
        </dtml-in>
      </tr>
      </dtml-in>
    </table>
    </dtml-with>

My point, I guess, is to suggest that this should be a built-in method
in a ZSQL query.   Unfortunately this would also hard-code the
appearance of the table unless it had lots of options.

I'm probably missing something.

I did find code that kind of did this in the manage_test method in the
ZRDB/DA.py file, but when called returns manage_tabs, and also access
some non-dtml-accessible functions like result._serachable_result_columns().

I'm sure I'm missing something, but this doesn't seem accessible from DTML.

Once again, there is code to render property table forms, but it is 
buried inside lib/python/OFS/properties.dtml.  Once again, it seems
as if a standard method to generate a form for editing properties
would simplify creating applications by eliminating the need to
type in, by hand, the required forms.

I've seen a couple of pieces of code, both in the mailing list and
on zope.org to do this.  

The overall goal is to make it easier for beginners to whip up an
application without having to know too much about html forms and
formatting.  Plus to make the system easier to maintain by not having
redundant information (i.e. in the property sheet or query, and also
in the DTML that renders it).

Thanks for your time...

In my ongoing efforts to gain a bit of recognition for the capacity of
Zope, Python,  and all things Open Source, it looks to me as if Marketing
Matters, regardless of my wishes. Even if, to me, the validity of Zope /
Python is "obvious", it is not so clear to others, and especially others
who make decisions about tool selection. 

At some point, if Zope / Python is to find a place in the larger world,
these folks must be convinced. There may be a more palatable word, call it
"education", "concsiousness raising", or some other more trendy phrase.
Still, you can get the gist from the words, "selling", "marketing", or even
"hype".

Check out some of the articles by the folks at Bynari Associates (any
search engine will get you there). You can see the need for marketing of
Linux and Open Source tools in their daily business. In fact, the articles
themselves are a form of marketing, gaining name recognition for Bynari
(see, it works!) in the Open Source community, while sharing the benefit of
their "real world" experiences of implementing "Linux" for paying clients. 

In short, the line between the coder and the customer relationship doesn't
look quite so distinct from here.

Later,

added to the instance in the form of properties, such as the description of
the task and which department it is created for).

The form that is used to submit a creation action resides in a created
folder (http://diis/tasks/generator) and therefore does not reside in the
folder where the DCTaskClass_add method resides. I think that my main
problem, though I could be wrong, is that I haven't found a way to access
the _add method from the /task/generator folder through the use of the
<FORM ACTION="...">. I believe that once I have can access that file
through the form action and have the ability to send all of the relivant
information I will be able to create instances through the use of the
public interface (ie. the form)

Any help will most appreciated.

Best regards, 

MJ Stahl

I shouldn't be that hard for you to write one yourself. I once wrote a function 
in perl using it's powerful patern matching which stripped out all HTML 
tags from an input text file. As I recall it took only 4 or 5 lines of code 
(including the function header). You should be able to do something similar 
in Python.

If you have a programmer and a web designer around it's possible to 
seperate the two tasks quite well, though, in my experience. Likewise a
situation with a programmer and a content manager, which is the situation
I'm in right now.

Still, both the web designer and the content manager want to know more
about Zope, and this does throw them off into the deep end (Python,
DTML, object oriented programming, etc).

I won't chop it off; you're right. Though I would say a simpler DTML
is only half of the story; the other half of the story is already there --
people _can_ use drop-in components. It's just that we need more and
better drop-in components (with possibly a nicer interface, ala Zope PTK
and/or Zope Mozilla).

Still, a simple variety of DTML would be nice. Currently you can
successfully use a subset of DTML, which almost has no arcaneness but
is still very powerful. PythonMethods will help even more there. Still,
DTML allows too much, so it's too easy to move into the arcane domain. Also
some of its powerful features have the side effect that some of the simple
features look too complex.

So perhaps we should create a seperate language, based on the subset,
with simplified syntax, which _doesn't_ allow fancy stuff. The fancy
stuff would be in DTML-methods or PythonMethods of some kind. Perhaps 
even the HTML would be in seperate methods. Perhaps some XML-ish Zope
glue language, like this:

<zopeglue>
<var object="header"/>

<assign name="age" object="get_age"/>
<var object="show_age_intro" arguments="age"/>

<var object="layout.table_header"/>
<in object="get_above_age" arguments="age">
<var object="myrecord" arguments="in_item"/>
</in>
<var object="layout.table_footer"/>

<assign name="age" object="getage">
<var object="footer"/>
</zopeglue>

And then some IDE that allows you to easily create all objects you
refer to here. Perhaps something wiki-like; any object name that you refer
to in the glue that can't be found will be presented in a list after you
edit the glue, and you can create objects for it then.

Ideas, ideas, now for some time. :)

Martijn

I would recommend taking a look at how the management interface does things.
(Just do a View Source in the Zope management frame that has the pull down
menu listing the different things you can add).

In KM|Net News, I made the incoming article form post to a DTML method
(AddArticle) that basically follows the steps in the "Adding ZClass
Instances Programmatically" how to.

http://www.zope.org/Members/tazzzzz/addZClasses

I haven't tested this, but posting your form to:

"manage_addProduct/YourProductName/YourZClass_add"

may do the trick, assuming your form is being called from the Folder where
you want the new instance created. Otherwise, you should do something like:

"/FolderForNewInstance/manage_addProduct/YourProductName/YourZClass_add"

The new scheduled DTMLMethod product, ZScheduler, can do that. Just schedule
the method for "now". Only works with DTMLMethod's but they can call any
other kind of method. The product is in alpha stages right now, so I
wouldn't use it for a production environment just yet, but I would
appreciate knowing whether it's useful for your application.

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time. 
The Z2.log file shows
123.123.123.123 [08/Mar/2000:16:49:40-0700]

The actual system time is  8:49 pacific time.
NT 4.0 show   (GMT-0800 UTC)  Pacific time (US and Canada);Tijuana
It and is set to automatically adjust for daylight saving time.  

I have a NT 4.0 windoze  workstation machine that is running Zope latest version 2.1.4. and of course python 1.5.2.
  
Is there a script file that needs adjusting to make the file log correctly?  I know that -700 is UTC is Mountain Standard Time.  Do Zope programmers like the warm southern climate better than the cold  climates?  In short can this "default" be changed.

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

Subject: [Zope] Setting title in an external method
Message-ID: <20000308121007.A561@cnri.reston.va.us>

Hi all --

A common idiom around here is to use an external method to process a
form and, if an error that the user can't fix occurs -- eg. you can't
view such-and-such an object because it doesn't exist, or you don't have
privileges -- use "return" to show them the contents of a DTML method
that explains the problem.

Here's a simple example:

    def my_xm (self, REQUEST=None, RESPONSE=None):
        # ... churn away, processing the form ...
        return self.my_dtml (self, REQUEST, RESPONSE)

Here's the source for the "my_dtml" DTML method:

    <dtml-var standard_html_header>
    title: <b><dtml-var title></b><br>
    document_title: <b><dtml-var document_title></b>
    <p>
    This is the <dtml-var document_id> Document 
    in the <dtml-var title_and_id> Folder.
    </p>
    <dtml-var standard_html_footer>

Both "my_xm" and "my_dtml" are in the root directory of an almost-fresh
Zope 2.1.4 installation.

The problem is that the "title" when I call "my_xm" (ie. the "Title:"
HTTP header and "<TITLE>" HTML tag) is just "Zope", which I presume is
the title *of the folder* containing the external method.  Yuck.  I want
the form result to have a title of its own, eg. "Error Viewing
Blah-blah".

What's the best way to do this?  Possibilities that occur to me:

  * redirect to the error-reporting DTML Method instead (but I like
    to keep the number of redirects to a minimum)
  * use a DTML Document instead of a Method (not sure if this will
    work, and sometimes I really do want it to be a method -- eg.
    it might be called from within a larger Document in some context)
  * set some magical attribute of 'self' or 'RESPONSE' in the external
    method; I tried "RESPONSE.setHeader ('Title', 'My Title')", but
    that didn't work

Any other ideas?  Thanks --

        Greg

(what the heck does the DCTask%20 do?) Before it couldn't find the product
DCTask (attribute error) and now it finds the product but I get a key error.

Error Type: KeyError

This is the code that I have for adding the adding ID of the instance of

Try htmllib.

The following bit of python will strip all formatting from some HTML. It 
replaces all anchors with footnote style references and images with 
their alt text. If you want something a bit fancier you could add 
methods to the MyParser class to pass through particular tags (see 
the commented out methods as an example). It shouldn't be too hard 
to wrap something like this up in an external method (as presented it 
is a complete runnable program that retrieves a URL and displays 
the text).

--------- File strip.py --------------
# Strip all HTML formatting.
import sys,formatter,StringIO,htmllib,string
from urllib import urlretrieve,urlcleanup

class MyParser(htmllib.HTMLParser):
    def __init__(self):
        self.bodytext = StringIO.StringIO()
        writer = formatter.DumbWriter(self.bodytext)
        htmllib.HTMLParser.__init__(self,
            formatter.AbstractFormatter(writer))

    def gettext(self):
        return self.bodytext.getvalue()

# Uncomment these to pass through bold tags.
#    def start_b(self, attrs):
#       self.formatter.add_flowing_data('<b>')
#
#    def end_b(self):
#        self.formatter.add_flowing_data('</b>')

def GetPage(url):
    try:
        fn, h = urlretrieve(url)
        text = open(fn, "r").read()
    finally:
        urlcleanup()
    return text

if __name__=='__main__':
    data = GetPage(sys.argv[1])
    p = MyParser()
    p.feed(data)
    p.close()
    text = string.replace(p.gettext(), '\xa0', ' ')
    print text
    anchors = p.anchorlist

Subject: [Zope] Object Manager and Folder
Message-ID: <E12SkGf-00074X-00@home.delysid.org>

Hi.

I am quite new to Zope and currently try to create a BookClass ZClass Product.
I came across several issues where you probably can give me some useful tips:

1. What is the difference between inheriting rom Object Manager and/or Folder.

2. My product will include Cover Images of the books. (a small and a large one).
Whats the best way to implement this? I thought about creating emtpy images (smallcover and largecover),
but I dont know how to ask the Objects if they contain something.
Or should I just add the Images in my BookClass Instance programmatically?

3. Wasn't their any web-client product for Zope so that I could retrieve content from the web directory and import it in Objects (like a Image) without having
to upload it manually?

And the last one:
Is their any special reason why FTP access doesnt work in the /Control_Panel/Products folder?
All methods are empty their. I work with Emacs and ange-ftp is quite
a good method to access content of Zope Objects.

Besides, if I change the content of a Object through the web interface,
Zope seems to convert < > and " chars into &lt; &gt; &quot;
I understand why, but is this really necessary. It seems as if nearly all
textmode browsers (as lynx and emacs/w3) dont care about converting the entities back tto their corresponding characters.

Thanks in advance,
               Mario <mlang@delysid.org>

If you can figure out improvements on how to configure UW IMAP for
interoperation with WorldPilot that would be great. We're currently
lacking 
a UW IMAP server with a reasonable amount of data on it for looking into
the
issues.
I'm putting in a parameter to control the LIST call, I think that should 
reduce the load for the large part of the users, but we're open for any
further
adaptions.

Ryan

I am hoping to add some performance benchmarks, quotes, etc... In other

Message-ID: <OFA5CFA31F.A45A80B0-ON8525689C.006234C6@ssga.ssb.com>

I just installed Zope (on NT) and would like to have reasonable
backup/recovery options.  One way to do this is to just make a copy of the
data.fs file in the var directory, but I'm concerned that this file may not
be in a consistent state when it gets copied somewhere.  Should I worry
about this?

I'm thinking it would be better to eliminate this file in favor of an
Oracle or Sybase database (I have access to both).  Can I do this?  If it
is possible, would I want to do it?  If I should want to do it, how do I do
it?  I've spent a few hours searching the documentation, but this has only
convinced me that it may be possible -- I've been unable to find a
definitive answer.

Ok that seems to work because I am getting other errors and I think this
task is a little advance for a zope infant like myself. Now, this line is
causing me problems (this happened after I called entered the hidden field):

<dtml-call "REQUEST.set('id',_.str(_.int(id)))">

The error it gave me was:

Error Type: ValueError
Error Value: invalid literal for int(): generator

It seems to be refering to the "(.int(id)))" of the above code.

Dave & Chris,
Thanks for replying.
I'm running Caldera OpenLinux 2.3.  I chose it because I heard that it had
one of the smoothest installations.  I am only a few months into Linux; I'm
transitioning over from the Dark Side (Microsoft).  Heehee.

Here's my best guess at what's going wrong with the MySQLDA/db installation.
I think it is related to access rights or locations to the
libmysqlclient.so.6 file.  When I run build.py, I can see the script
accessing the MySQL library folder (in my case: /usr/local/lib/mysql)  This
is the path the MySQL 'make install' script displayed when it was done
installing MySQL.  I checked, and the library files are there.  Anyway, I
can see the build.py script working some of its magic within this folder, so
I feel confident that the paths in the Setup.in file are correct.  However,
it is crashing when it tries to "from _mysql inport *".  I am not (yet) a
Python programmer, so I don't understand the implications of this import.
I'll reprint the error message I received for anyone else that reads this:
Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I like your idea of making a link to the MySQL library file
(libmysqlclient.so.6).  I know this is a stupid question, but if I run:
ln  /usr/local/include/mysql libmysqlclient.so.6
what will the link be called, and where will it be located?  How will this
help the build.py script?

Thanks again for your input!


Chris,
This seems to be pretty common which makes me feel, well, not alone...

Thanks for the note and I'll keep you updated on my progress.

Here's what Dave Curtis sent me earlier today.  He reinstalled EVERYTHING
and it worked, but I'm not ready to go that far yet.  Maybe something in
here will help you...

Ok, about your problem, this is where I also got stuck. Here is my solution.
I reinstalled linux (probably didn't need to but I did)  I used an older

tell you anymore.  Well, use can try using a link
# ln  /usr/local/include/mysql libmysqlclient.so.6
and see if it can now find the libraries/files it needs.

Are you sure that the Setup.in path is correct?  I looked at both these
files build.py and MySQLdb.py they both refer to libraries and their
respective location.  Anyway good luck and if you get an answer, please let
me know also.  I am curious what O/S your are using and why you choose it.
I probably going to change over to mandrake linux for security reasons.

I've never used Caldera's distribution, but if it's anything like Red Hat,
the following should work:

1) Open /etc/ld.so.conf with your favorite text editor and append the
directory in which libmysqlclient is located.
2) Run 'ldconfig'

This will update the list of directories that the linker searches.

Let me know how it goes.

I am impressed with the products I've seen so far but they can always be 
improved and there's certainly room for more. Perhaps there should be a 
coordinated 'wish list' on zope.org so that developers can pick up on 
needed products, or collaborate  on enhancements of existing products ?

Well that's a bit further than I was proposing. Perhaps I would settle for 
dtml which accessed the REQUEST object more simply. However your syntax 
looks good.

Yes, spawn a new thread.

WARNING this can cause havoc if not done properly.  For example, if you
want your seperate thread to be able to read and write data to the
database, you MUST open a seperate connection to the DB.  If your thread
goes away, you MUST close that connection.  There are a couple how-tos
on the site that explain database connections.

Yes, that makes sense. When it looks up "id" in the namespace, it first
comes across the id of your method. You're specifically wanting the "id"
from the REQUEST variable. So, the line should be:

<dtml-call "REQUEST.set('id',_.str(_.int(REQUEST['id'])))">

Nope. The Data.fs file is simply appended to when things change, and it is
quite safe to just copy the file over.

It *can* be done, but you would need to write your own ZODB Storage
mechanism for it. Right now, there are a few Storages available. FileStorage
is the most common (the one that works with Data.fs). There is also
CompressedStorage and BerkeleyStorage. No one has written a storage for an
RDBMS yet, but it should be possible.

Would you want to do it? Probably not. The FileSystem storage is pretty
solid. About the only thing you'll get from the RDBMS storage is that you
wouldn't have a file that keeps growing with every transaction and needs to
be packed from time to time.

Hi Chris (Carlson),
Thanks for the reply!

1.  I added the following line to my /etc/ld.so.conf file:
    /usr/local/lib/mysql
2.  I ran 'ldconfig'
3.  I re-ran build.py.  Here is the new error message. (notice that the last
line changed from before):
Traceback (innermost last):
   File "build.py", line 14, in ?
     import MySQLdb
   File "MySQLdb.py", line 19, in ?
     from _mysql inport *
 ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

Note that the file '_mysqlmodule.so' is in the
'/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' directory

4.  I tried adding '/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' to my
/etc/ld.so.conf file, re-running ldconfig, then re-running build.py, but I
got the same error.

It seems like we are getting a little closer!  Any more guidance would sure
be appreciated!

Thanks again,

Eric.

Subject: [Zope] Zope authentication problem
Message-ID: <v04220807b4ec46d1b515@[192.168.0.16]>

I apologize in advance for this note. I know this topic has come up 
several times in the archives, and I swear I've read every post, 
every how-to, and every other bit of documentation I can find. I 
can't get past the management screen authentication for Zope with 
Apache.

Here's my environment:

OS:		RedHat Linux 6.1

Zope: 		version 2.1.4, installed from Jeff Rush's RPMs (thanks, Jeff)

Zope PCGI:	version 2.1.4, also from Jeff Rush's RPMs (thanks again, Jeff)

Apache:		version 1.3.9, installed from the Red Hat RPMs (both base
		and devel RPMs are installed)

Python:		version 1.5.2, from the Red Hat RPMs


I'm configured as follows:

Zope install directory:		/var/zope

Zope.cgi:			copied to /home/httpd/cgi-bin/Zope
				(not a symlink, and renamed 'Zope')

access file:			/var/zope/access, contains:
				admin:cleartextpassword

httpd.conf contains:

RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/static/(.*)   /home/httpd/html/$1 [l]
RewriteRule ^/Zope(.*) /home/httpd/cgi-bin/Zope$1 
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

(that last line is all one long line, and I'm pretty sure I've sorted 
out the ls and the 1s properly)



Zope is launched with the following command:

cd $INSTANCE_HOME  (/var/zope)
/usr/bin/env python z2.py               \
         -z      /usr/share/zope         \
         -u      zope                    \
         -Z      /var/run/zwatchdog.pid  \
         -p      /home/httpd/cgi-bin/Zope \
         -w      ''                      \
         -f      8021                    \
         -m      ''                      \
         -l      /var/log/zope           \
         2>&1 >> /var/log/zope           \
         &

I can access all my other (non-Zope) CGI programs normally. I can 
access my static html with URLs of the form:

	http://server.ucop.edu/static/some_silly_url.html

So, I'm pretty sure that both CGI and the rewrite modules are 
installed, configured, and working properly. I can run Zope and see 
the QuickStart materials, so I'm pretty sure that the basic Zope 
installation is correct. But I can't get authenticated to Zope. 
There's nothing in the logs for httpd or Zope that looks interesting 
to me:

httpd - access_log:

207.212.67.31 - - [08/Mar/2000:10:14:18 -0800] "GET 
/cgi-bin/Zope/manage HTTP/1.0" 401 1388

Zope log (syslog messages file):

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- - 
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782

/var/log/zope is empty.


I've tried about a zillion other things, including installing the 
Zope binaries instead of the RPMs, and installing and building the 
Zope source. In every case I end up with the same result. Zope 
doesn't accept the authentication. One oddity I noticed is that if I 
access Zope through:

	http://server.ucop.edu/Zope

it immediately requests authentication. It doesn't even show me the 
opening screen or allow me to browse the QuickStart. If I dodge 
around the RewriteRule by going directly to:

	http://server.ucop.edu/cgi-bin/Zope

then it doesn't ask for authentication until I try to hit the 
management screen.

I should probably add that I tried using the built-in Zserver Python 
package and it worked fine. I haven't tried Zap. I would prefer to 
use Apache because I want to serve a mixture of legacy HTML and Zope 
content. I would prefer to use my own Apache instead of Zap because 
in general I'm not comfortable with using a package that I can't 
maintain at the current release level. Zap Apache trails plain Apache 
releases, at least by a little bit. I've tried a whole raft of 
variations on the rewrite rules in Apache. I'm stuck.

Anybody out there been through this already?

Try just REQUEST.set('title', 'Foo')

Folder inherits from all kinds of other things, including
ObjectManager.  Basicly, if you want your object to be a container then
subclass ObjectManager.  If you want to look and walk and quack exactly
like a Folder, use Folder.

They have a getSize() method that returns the length of the Image (Files
have this too).

Sure.

Yes, any automatable HTTP client will do.  You might want to look into
ZClient, or xmlrpclib, or httplib.

Yes it is, I'd like to see this too.  I don't think it would be too
complex for someone to do, certainly FTP support is fairly trivial.  For
this you would need to mine the source.

I don't understand.  Editing a DTML Method through the web should not
munge it in this way.

Create an new kind of Storage module that stuffs database records into
table rows, instead of a file.  We've hypothisized on this, and it is
very possible (the 'fs' in Data.fs means 'FileStorage', which is the
kind of storage used by default on Zope.  Other storages include
DemoStorage, BerkeleyStorage etc.  There is no saying you couldn't have
a RelationalStorage).  Butdo you REALLY want this?  Consider:

1) Relational databases do not store previous revisions of record
information.  You will have no Undo capability.  I guess with some
extremely fancy SQL or if you engineered the Storage to do some kind of
mapping, you could emulate the storage of previous revisions.

2) One of the benefits of RDBMS is that they can be used by outside
applications.  The data Zope stores however will be record objects,
basicly python pickles, information which is useless to other apps.

However, it's really not a bad idea, except for the no Undo part.

Yer gonna kick yourself if this is it, but I believe that you must have
a RewriteCond before each rule that you want the conditon to apply to,
so in this case your authorization information is poked into the
environment for your static content, but not Zope.

Duplicate the second line after the third and see if it works.

Subject: [Zope] Referencing a Zope Instance through a Hyperlink
Message-ID: <3.0.1.32.20000308144541.0068c798@bizux.net>

I have a group of ZClass (DCTasks) stored in a folder
'/tasks/generator/taskstorage'

The index_html of '/tasks' is the interface to view the instances and
certains properties that are saved on those instances. One of the
properties is 'task_title' and is displayed as a hyperlink to view the rest
of the properties of the instance.

This is my problem, when I check the source of the page (/tasks/index_html)
and I take a look at the hyperlinks for viewing the properties of the
instance, it gives a URL like so:

http://diis/tasks/generator/taskstorage/<string>

<string> should actually be replaced with the 'id' of the instance. This is
so by the DTML code for index_html:

<a href="<dtml-var URL1>/generator/taskstorage/<dtml-var id>">
  <dtml-var task_title>            
</a>

I have no idea why a string is taking the place of <dtml-var id> in
referance to the instance.

Any ideas would be helpful.

Best regards,

Well, basically what you are doing here is moving the point of
potential corruption from zope to the relational database.  This may
or may not give you any comfort.  For me, it makes me more nervous
since I don't have the source code to those particular databases, and
thus couldn't fix things if the worst does happen.

World domination has nothing to do with it. If Zope were the only tool
out there (or if it were enjoying the same kind of monopoly iron grip on
the market), that'd not be a Good Thing.

At the moment, Zope is still very much a "guerilla" product. It follows
that you might have to use guerilla tactics to lure it into your
company. Like Linux was just 1-2 years ago.

Arguably, free software (or Free Software) is about freedom, not
necessarily about what's right or what works.

RMS, arguably the grand old man, top banana, and icon of the Free
Software movement -- which is not the same as Open Source -- openly
admits he'd rather have bad, free software than good, non-free software.
The Open Source movement takes the pragmatic view that bad, free
software isn't an improvement at all, and that the software industry has
little use for RMS' moralisms. The Open Source guys just wants "software
that doesn't suck".

Perhaps Free Software people don't care about marketing. But then making
good impressions or having good hygiene has never been top priorities
for geeks. ;-)  For some people, outward perceptions do count. I flinch
every time somebody sets up Microsoft Exchange Server, or buys some
pricey piece of non-compliant Internet software, or seriously argue the
significance of ASP.

The people who make such decisions are often, sadly, uneducated about
what's good and about "software that doesn't suck". *Other* people
suffer because of such misfires.

Here's a different perspective you might not have taken into account in
your salutations to the spirit of Free Software. If Linux *hadn't* been
picked up by huge corporations and stock markets, if Linux *hadn't* been
rampantly commercialized, would we have seen the surge of wonderful
developments and innovations for the OS that we're seeing now? Methinks
not.

As much as I abhor commercialism and the new Linux hype, Linux' implicit
"world domination" plan is doing good things for the OS. Linux is not
the ultimate OS and hopefully won't be the last stop on the way to
utopia, but I rather look forward to the point where it's usable as a
desktop OS and I can forever throw out the software I know for a fact
sucks.

Marketing, in the case of Open Source/Free Software, is mostly a tool to
educate ignorant brass. *We*, as you point out, don't need the stuff.

Subject: [Zope] Puzzling DTML method results
Message-ID: <4.2.2.20000308154134.00b99280@saladin.aisys.com>

I'm encoutering a puzzling result with some DTMLMethods that I've 
written.  I have some code which is used to display a list of information 
derived from a catalog.  The information presented varies, based on which 
"category" of information the user desires.  The DTMLMethod which generates 
most of this information looks like this:

<dtml-in "InternetLinkCatalog(meta_type='Internet Link Info', 
categories=_['categoryName'])" sort=name>
    <dtml-with "InternetLinkCatalog.getobject(data_record_id_)">
        < ... display object stuff here ... >
    </dtml-with>
</dtml-in>

For testing purposes, I created another DTMLMethod in the same folder named 
'categoryName' and initially all it contained was one line:

Accounting

When I displayed the contents of my folder (which utilizes the list 
generation method),  I received a list of all objects which belonged to the 
category of Accounting.  I'm now trying to extend my code to use an actual 
category name specified by a user (or from a url clicked on by the 
user).  I changed my 'categoryName' code to look like this:

<dtml-with REQUEST only>
<dtml-if category>
    <dtml-var category>
<dtml-else>
Accounting
</dtml-if>
</dtml-with>

If I view this method, the result is 'Accounting', which is just what I 
would expect.  However, when I attempt to view my generated list in the 
same manner as before, I get no results.  I'm confused.  When the 
categoryName simply has the value 'Accounting' in it, I see results.  If I 
change the method to include some processing (but still answer the same 
thing), I get no results.  I'm sure that I'm just doing something stupid a, 
but it's getting late in the day and I'm not seeing what the problem might 
be.  Can someone help explain why I'm getting two different results for 
what should be the same?

Thanks.

I bet your ZClass inherits from either DTML Method or DTML Document, and
then the following article applies:

Or going to be available?

kb

>>> From: Patrick Phalen <zope@teleo.net>:

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

I can't see the problem either, but I suggest changing your method to
this:

<dtml-if category>
  <dtml-return category>
<dtml-else>
  <dtml-return "'Accounting'">
</dtml-if>

The <dtml-with> is unecessary.  Note the single quotes inside the double
quotes.

This might fix it, might not, not sure.  But here you are explicitly
returning a string, not a formatted document.

Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AC@VRTMAIL>

I'm attempting to create a directory list (well, the final version will be
more complex, but this is where I'm stuck).  I'm looking for some way to get
the creator ID for all of the (file) objects in a folder.  I'm also
interested in getting the mimetype, but this is less critical.  Here's what
I have so far:

<dtml-in "PARENTS[0].objectValues( ['File'])">
url <dtml-var URL1>/<dtml-var id>
title <dtml-var title>
id <dtml-var id>
size <dtml-var size>
ddate <dtml-var bobobase_modification_time fmt="%m/%d/%Y">
owner 
mimetype <dtml-call "getContentType()">
</dtml-in>
<dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')">

Unfortunately, getContentType always seems to return null strings, and I
cannot find any attribute which shows the owner/creator attribute of the
object. If the creator is not available, the last editor would be fine.

Pointers appreciated,

logged_in.html then checks <!--#if "AUTHENTICATED_USER.getUserName() !=
'Anonymous User'"--> and reports success or failure.

However, as usual, there's got to be something I'm missing.  If I simply
build those two pages, the AUTHENTICATED_USER.getUserName()  check on the
logged_in.html page always return 'Anonymous User'.

When and how do I get the form to actually 'chat' with Zope and make me a
valid authenticated user?

Thanks in advance for any help provided.

For those who are still having a problem with DCOracle and Oracle8i, that's
working great for me now.  If I can help, feel free to send me email.  I'm
running all this on RH Linux 6.1

I've been watching this debate since the begining and felt I'd put in one
observation on the above quotation. I actually think one of the comments in
this vain (maybe by ESR) was the goal for "software that sucks less" than
the whats out there. I don't think you can create software that doesn't suck
in some person opinion.

That said what I've learned is if I have to have software that isn't quite
where I want it to be I prefer the ability to adapt it myself. One argument
against open-source software projects is that they often come from amorphous
groups on the Internet. (Zope is an exception.) As a result there is no one
to "hang if it fails". What people don't factor into the equation is if I
have to pay $X for licenses from a vendor (with or without a support
contract) how many hours of contractor time will that buy me to install,
customize, administor, and maintain a freely available open-source product?

For those fighting this battle inside corporations I recommend

That did the trick.  I hadn't thought about putting primes around a value

Hello Zopistas -

FSSession 0.3.0 is available at:
http://www.zope.org/Members/gaaros/FSSession

FSSession 0.3.0 corrects a few reported bugs and has now working support
for Zope Transactions (thanks to Hung Jung Lu for valuable discussions).
Users of FSSession should upgrade to the newer version. Feedback
especially regarding speed will be appreciated.

People are indeed working on Python, but not to the extent of more
popular projects like Linux or even, I believe, Perl.

Compiler/language projects have, historically, not thrived in the
collaborative world of open source software -- for very specific reasons
inherent in the concept itself of languages and compilers. Still, I'm
very impressed with the evolution of next-gen GCC (formerly EGCS).

I consider Skaller's Vyper project a fringe project with limited
applicability, because Ocaml itself is a fringe project -- it's
certainly not what you might call a mainstream, popular language.
There's something icky about an OcamlPython. However, I'd love for it to
succeed. (Unfortunately, Skaller is already out on a limb, implementing
all sorts of stuff he deems interesting -- so true CPython compliance
isn't necessarily on his agenda, and fragmenting Python like this is,
imho, not a good thing.)

Anyway, while I have not been monitoring the Python type/interface SIG,
it seems to be moving quite slowly.

I'm not saying they're holding back, but rather they're dismissing speed
and scalability as being a problem. I firmly believe that speed is
Python's number of problem today, and it's keeping Python from being
used in more applications.

Python has plenty of problems, but they're tiny by comparison and imho
they're mostly artifacts of Python's currently somewhat anemic syntax
(eg., only two kinds of loops, no "switch", no protected members, no
constants, no syntax for declaring mutability).

Imho Python's second big problem is what you might call, in lack of a
better term (I'm not wearing my compiler-writer hat right now, sorry),
contractual semantics -- anything from static typing (pass a string to a
function that takes an int and you get either a compilation error or an
exception) to interfaces (the ability to enforce semantic compatibility)
to design-by-contract constructs.

I disagree, but there's only one way to find out -- implement it (or
simulate it very carefully).

Not potentially. Definitely. I thought about this yesterday, and I got
to thinking that it would probably be pretty simple to create a dynamic
native-code generator that translated bits of bytecode on-the-fly, with
the necessary stubs implemented in a small helper-assembler written in
C. Something like:

  def Halibut():
    ...

  import codegen
  c = codegen.Translate(Halibut)
  c()  # Call native-code function Halibut

and then with whole modules:

  import pickle, codegen
  pickle = codegen.Translate(pickle)

Internally, Translate() would disassemble the bytecode, generating
native assembly language code and pass it to the helper C module, which
would store it in an executable buffer and fix up the necessary
references to the Py* API symbols.

Just a thought.

It would be an interim solution for certain CPU-intensive modules, in
anticipation of such built-in functionality in CPython itself. Possibly.

Well, I guess they're too busy arguing about whether Python should allow
assignments as expressions so you could do "while line = f.readline():".

Thanks,
The problem is fixed. The box with the ftp server had PARANOID host 
deny settings. This caused user's with incorrect reverse IP lookup
nameserver settings to be disconnected.
Sorry :-( 
You should all be able to download now (but maybe get in touch with
your domain administrator/ISP and get your DNS entries corrected, if
you previously had trouble ;-)

Cheers,
Ryan

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * A Documentation Survey has been posted.  This survey will help
    Digital Creations decide where to focus our efforts by allowing
    you to tell us what you think about Zope documentation.

    http://www.zope.org/Members/Amos/Documentation/DocSurvey

  * "efm" has made a set of RPM distributions of Zope 2.1.4.

    ftp://www.tummy.com/pub/tummy/RPMS/

  * Maik Röder has posted an announcement regarding the Zope
    Documentation Project (ZDP).  Among other things, the ZDP has a
    new site.  It's a fantastic resource, and definitely worth
    checking out.

    http://www.zope.org/Members/roeder/zdp

  
New Products

  * Software Product: NFG Navigation Product, submitted by "gyst"

    Another product which provides navigation widgets such as trees
    and maps.

    http://www.zope.org/Members/gyst/NFGnav

  * Software Product: ZopeEDIT, submitted by "jimbag"

    This product allows you to edit DTML object from your Zope
    database in your favorite text editor.  Maybe.  Written in Python,
    so it just might work on your machine.  This is _not_ a Zope
    add-on, it runs on it's own.

    http://www.zope.org/Members/jimbag/ZopeEDIT


Updates

  * Software Product: mod_pcgi2, submitted by "phd"

    The update to 1.0.2 adds new documentation.  This is module allows
    Apache to communicate with long-running PCGI servers, such as Zope.

    http://www.zope.org/Members/phd/mod_pcgi2

  * Software Product: load_site.py with additional features, submitted
    by "Itamar"

    This is an enhancement to the load_site.py utility that comes with
    Zope.  It can be used to fill a Zope database with content from a
    filesystem.  This release, version 1.2, fixes all known bugs, has
    new features from the newest version of the original load_site.py,
    and runs in 'standalone' mode, loading into a remote Zope server.

    http://www.zope.org/Members/itamar/load_site/load_site1.2

  * Software Product: FSSession, submitted by "gaaros"

    FSSession allows you to store persistent, per-visitor information
    on your filesystem.  This update, to 0.3.0, fixes a number of bugs
    and properly supports Zope transactions.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: KM|Net News, submitted by Kevin Dangoor

    KM|New News is a weblog (news site) product, not unlike (but not
    identical to) Squishdot.  This update is version 1.1.

    http://lists.zope.org/pipermail/zope-announce/2000-March/000122.html
    http://www.zope.org/Members/tazzzzz/kmnn


Zope.org items

  * How-To: Managing http/https URL Links, submitted by "rbickers"

    This How-To describes a clever method to generate links to objects
    which require different protocols (http or https).  This allows
    you to use encryption only where needed, without using exclusively
    absolute links.

    http://www.zope.org/Members/rbickers/http_https_ulinks

  * How-To: How to view all inherited and acquired attributes and
    methods of an object, submitted by "dmost"

    This How-To is essentially an educational (or debugging) tool.
    Often it's difficult to figure out what methods an object has, or
    where those methods are coming from.  This How-To provides an
    external method which lays it all out for you.

    http://www.zope.org/Members/dmost/ViewSelf

  * How-To: User Defined Roles and Proxies, submitted by "lvogel"

    "This HOWTO is to give a brief explanation of what a user defined
    role is, why you would want to set one up, and how to go about
    creating one. I also briefly touch setting up a proxy on Zope
    objects."

    http://www.zope.org/Members/lvogel/proxy

  * How-To: Change TinyTable values using DTML, submitted by "cguardia"

    "The TinyTable product is a good tool if you need simple table
    lookup functionality in your Zope apps. However, it's usefulness
    is limited by the fact that it doesn't support writing single
    values to the tables you create."

  * How-To: RESPONSE.write with ZServer 2.1.4, submitted by "htrd"

    "Streaming output does not work in Zope 2.1.4, when using ZServer
    to serve HTTP. This is fixed with the following two files..."

In my case, they were, for IMAP, my local machine name, and for SMTP, my
ISP's (Roadrunner's) SMTP server.
IMAP has always worked great.  SMTP has been the problem.  I have not tried
Jack's solution, as I can't use localhost
for SMTP.

Thanks for any help,
Matt

I am getting a strange error when I try to access the Properties tab of
one of my objects called "News":

ErrorType: InError
ErrorValue: Strings are not allowed as input to the in tag.

The traceback is as follows:

Traceback (innermost last):

InError: (see above)

What does an error in the input to an "in" tag have to do with accessing
the properties tab?

I could be wrong, but I suspect that this has something to do with an
assignment I made to a lines property that belongs to the "News" object.

Something to the effect of a string being assigned to a lines property?
(I make this assumption because I have had this error come up before
with lines properties. In this previous case, I just flushed out the
contents of the lines property in question using
"manage_changeProperties". This fixed the error, although even then I
never understood what the error in input to an "in" tag had to do with
the lines property value being erroneous.) As I no longer need this
property, I would gladly eliminate it. However, Zope won't even let me
in to the Properties tab. It just displays the "InError" when I attempt
to go to Properties of the News object. I can't really remember the
exact wording of the lines property id so I can't delete it via
"manage_delProperties" or flush out the contents of the property using
"manage_changeProperties".


Any insights as to what is going on and how to resolve this situation?
Please excuse the verbosity of this posting.

Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AD@VRTMAIL>

I know, bad form responding to one's-own post, but I did figure it out and
thought other newbies might find it useful...  The first (trivial) problem
was that I had a typo (dtml-call instead of dtml-var) which prevented the
content-type from displaying.

"type" "<dtml-var "getContentType()">"

The creator/owner attribute can be got at by going through the
get_local_roles method then searching for a value that has "Owner" in it,
and copying the corresponding key.  I'm sure my dtml is atrocious, but hey,
I just learned it this afternoon :) .

"owner" "<dtml-in expr="get_local_roles()"><dtml-let
temp=sequence-item><dtml-if expr="temp and 'Owner' in temp"><dtml-var
sequence-key></dtml-if></dtml-let></dtml-in>"

Enjoy all,
Mike

Having a slow machine, not having to restart the server when testing is
important for me (it is a 20 second start up for me).
Is there a script around to let me do this... ?

Here is what I have done so far (using bits of snippet from the source):

log into the monitor, and do this:

import Zope
app = Zope.app
c=app()
OFS.Application.initialize(c)
c._p_jar.close()
del c

The net result is all items in the the "Add New Item" combobox double up,
and I am not even sure if this does the trick...

Good idea. Zope needs some more languages anyway.
Apache for example has mod_negotiation for this.

please not: the q argument is not meaningless.

I think a better way would be to implement a true negotiation mechanism.
That is, if the request comes, zope has to look for languages available
and rates them according to the language preferences coming from the UA.
Then it sends out the highest rated document, that might be the first
of the items in accept-language.
So each document (could be a folder?) schould have an attribute to
identify
its language capabilities. 

A simple branch would imply you have all documents in all requrired
languages.
I in doupt you can make this happen.

Easy with a second string.split(_.['sequence-item'],";")[0]

Subject: [Zope] Documentation survey
Message-ID: <14534.58177.603725.668441@antares.int.plain.co.nz>

As the tiny little text box on the survey page isn't up to long
dissertations, I'll post my comments here:

The guides need better examples and blank spots filled in, in
general. The DTML guide, in particular, needs a canonical explanation 
of the quoting rules and shortcuts so new DTML hackers understand why
you can get away with this:

<dtml-let foo=bar> ... </dtml-let>

But still need to do this:

<dtml-let foo="'constant'"> ... </dtml-let>

There is still a lot of docs using the old, ugly HTML comment style
tags, too, which is confusing, and there are a lot of examples of
using '_' and REQUEST to kludge up a temporary namespace when
<dtml-let> is the accepted means to kludge up a namespace[1].

The HOWTOs and Tips are potentially the basis of an excellent Zope
cookbook, but they require more stewardship from DC:

- They need more structure. Catagorizations like
'Authenication/Authorization', 'Using RDBMSs' and 'DTML tricks' would
save a lot of search time and provide hints towards missing
documentation. 

- The need to be vetted. There are a lot of docs with incorrect
examples and obsolete information that need to be tidied up. 

John

[1] Who the hell came up with a scoped assignment tag?! Why not
implement a <dtml-set> tag that isn't a container and that assigned to
a temporary namespace that persists for the duration of a DTML objects 
rendering. It can have a special attribute that you use to commit
changes made to an object in the temporary space back to it's
persistent name space, and you'd have a decent assignment tag.

It is the name of a method that will be called when the File is accessed.
You can use it for checking a session cookie, or anything you need from the
REQUEST.

If you then want to deny access to the resource, because your precondition
hasn't been met, the method can raise an exception.

I dont know if this is possible, but one feature of any tree-transformation
language that might be usefull to me would be the lazy construction of
nodes, or the creation of a virtual tree that is in fact a live view of the
source tree. XSL seems to be designed as a batch-processing language, which
seems at variance to the principles behind zope.

fmt="..." accepts any printf style formatting string.  Grab your handy C

No, sorry.  Python has a 'reload()' built-in, maybe that could be

Message-ID: <4.2.2.20000308192207.00e638e0@127.0.0.1>

I'm new with Zope.

One thing I'm looking for how to do is the effect that one document might 
virtually be stored in multiple folders.

For example, if I keep a hierarchy of folders that is an archive of 
articles, maybe stored chronologically in a folder for each month or 
something like that. But then I also want those same articles to appear in 
other folder hierarchies, categorizing and organizing them in various ways. 
And I don't just want to put duplicates of the document in there. I'd like 
that if somebody updates the original, the virtual documents in the other 
folders update too.

Is there some obvious DHTML statement or trick I don't know about yet? Or a 
Product that does something useful about this? Essentially I'm looking for 
an equivalent to symbolic or hard links to files in a Unix file system.

Subject: [Zope] what defines the absolute_url() prefix?
Message-ID: <38C72738.F8CB3EB8@picknowl.com.au>

G'day,

I'm having a blast using (technically: playing with :-) Zope 2.1.4 on
a RedHat 6.1 box, and mod_pcgi2 (1.0.1).  For my first efforts, I've
built a set of DTML methods which emulates www.python.org's style of
website, with an index_html method that "includes" Banner, Sidebar,
Body etc methods, which can be over-ridden in lower-down folders. 
All funky stuff, works well.

In the Sidebar, I have links to folders within the site using
absolute_url() (because of issues with BASE HREF giving me multiple
folder syndrome).  I can access the folder with the URL
http://localhost/cws/Help (and the logfile shows "GET /cws/Help"), but
the absolute_url() method on cws.Help is actually returning
"http://localhost/cws/cws/Help" (which is also accessible - kinda odd,
but not what I want).

I kinda suspect I've screwed the mod_pcgi2 config, mainly because its
the area I'm the most confused about :-)  I have the following config
in Apache:

<Location /zope>
    SetHandler pcgi-handler
    PCGI_ROOT /
    PCGI_SetEnv SiteRootPATH /
</Location>

<Location /cws>
    SetHandler pcgi-handler
    PCGI_ROOT /cws
    PCGI_SetEnv SiteRootPATH /cws
</Location>

(Oh, and I've just added a <dtml-var REQUEST> to the Help page, and
it's returning URL http://localhost/cws/cws/Help/index_html for
accesses to http://localhost/cws/Help, so it's awfully consistent
in its behaviour.

How does zope determine what the prefix is, and better yet, how do I
fix it to mesh with reality?


Regards,
  Daryl Tester

Flemming,

What you have described is exactly what Acquisition does.  Say you put a
document 'DocumentFoo' in your root level folder.  You could access that
document a number of ways:

/DocumentFoo

/AFolder/DocumentFoo

/AFolder/AnotherFolder/DocumentFoo

this happens for you automatically right now.  Try it youself, create
some folders, put a document somewhere 'above' them (like in the root
folder) and it will work.

Subject: [Zope] fast cgi
Message-ID: <003b01bf8988$d50e3960$0402a8c0@toil>

Exactly how do you get zope to work under apache with fastcgi?

I found 2 documents on the zope site dealing with this issue and they both have
command options "-pass-header Authorization" like
FastCgiExternalServer /home/httpd/html/z -host localhost:8999 -pass-header
Authorization

This produces an error as an invalid option, and looking at the documentation for
the FastCgiExternalServer directive it is not an option. The version of fastcgi
is 2.2.2 which is the same version they say to use in the documentation.

Does anyone besides Digital Creations know how to make this work? I have tried
this a bazillion ways from apache rpm's and binaries, but can't get it to work.
Someone must know how to do it.

Thanks

If you look around at Zope.org, you'll see that most content physically
resides in Member folders. But the same content can also be found through
the Documentation, Products and Reosurces pages.

We use the ZCatalog for this. You can build up pages with searches, thus
allowing multiple views into your content.

We are currently developing a thing called 'Topics', they exploit this
feature in an automated way. You specify a search on them, and they will
thus model a view into your indexed content. This way you can generate pages
with your articles by month, or by topic.

I think he typoed 0.2.3 instead of 0.1.2. 0.1.3 is out as of today (or
yesterday), but shouldn't offer any improvement in conjunction with Zope,
so you don't need to rush out and get it.

The main hurdle that people installing MySQLDA with MySQLdb seem to have
is, they want to try to compile the stuff in the src directory that
ZMySQLDA provides. This is MySQLmodule, which is the old interface. Just
rm -r src. There is a patch that comes with MySQLdb that needs to be
applied to ZMySQLDA. Once you've done these two things and installed
MySQLdb on your PYTHONPATH, you just need to restart Zope, and make a
ZMySQLDA Connection object (or whatever it's called).

I don't think a new syntax should be brought about. There are too many things
to learn already, it will only add to the confusion.

I do agree that dtml is complex and something needs to be done about it.
Probably a subset of the current dtml itself - with minimal additions which
make somethings easy - would be good.

Also (if this is seriously being considered) I would favour for a somewhat
different paradigm:

Instead of:
> <var object="layout.table_header"/>
> <in object="get_above_age" arguments="age">
> <var object="myrecord" arguments="in_item"/>
> </in>
> <var object="layout.table_footer"/>

We could have:
<dtml-var object="layout.table">
<param name="datasource" value="get_above_age">
<param name="columns" value="Name,Age">
</dtml-var>

The advantage here is that:
   o   One logical presentation element (a table) is one element in dtml code.

   o   One-to-one relation is possible between the code and any GUI entity
        being used to design (think ZStudio). This means the layout.table can
        be one icon that is dropped into a design view and it's parameters
        specifed through some fancy widget. 
        Also when the code is stored and reloaded, it would still be
        possible to display the same GUI entity in the design view and it's
        parameters would be editable.

Discussions on the above have taken place on the ptk and zope-moz lists.

That is a very peculiar error. Py_InitModule3 is a symbol from Python
itself, so if that's missing, I don't know what's wrong. Well, I can guess
a little, and my guess is, while you have Python installed, you don't have
the development libraries. With RedHat, this is python-devel, but may be
something else with Caldera. Actually, Py_InitModule3 is a macro in
Python.h, so if it's looking for that, then Python.h is probably not being
found, which could mean that the -I flag in Setup (or Setup.in) is not
right for your environment. But you would have all kinds of build errors,
I would think.

Try this:

find /usr/include -name Python.h -print

If nothing comes up, then the development stuff isn't installed, or it's
installed somewhere else.

Subject: [Zope] newbie tree q - how collapse and expand
Message-ID: <38C76321.43C0BBCA@open.ac.uk>

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Subject: [Zope] Zope Question : Virtual folders / URL's
Message-ID: <009301bf89a9$afced7b0$0201a8c0@iridium>

Have been reading the docs but still not clear on a few things.

I have my site mapped out in my mind. It has URL's like :

mysite.com/          (main page)
mysite.com/rss     (rss content for mysite)
mysite.com/<username>  (main <username> page)
mysite.com/<username>/rss (rss news content feed for <username> page)

Where I come from data belongs in a database. I'm happy for all my HTML to
be in the ZopeDB but not any application data (users definitions, news items
etc etc).

So, looking at my URLs I see that there are a mixture of static and virtual
folders.

mysite.com/index_html is obviously static though it contains dynamic
content. Doing this with Zope is easy and obvious.

mysite.com/Fred/ is a dynamic page. Fred only exists as a username in a
users table and related information in other tables. It's not obvious to me
how I go about serving this page because I can't create a static page for
every username (nor do I want to).

Clearly mysite.com/Fred/rss will use almost identical processing to the
mysite.com/rss page, just different parameters so re-using my "rss"
generating code is important to me too.

I'm know these virtual folders can be served up by Zope. Can someone tell me
what I am missing?

   You can even access

Last I heard about this, the status was "Not available".
http://lists.zope.org/pipermail/zope-ptk/2000-February/000323.html

But soon (hopefully!), I'll be releasing iTrack - an Issue Tracker Zope
Product. I haven't really used the ptk tracker so I can't give a comparison.

Cheers,
Shalabh

Well, it's a "feature" I can live with (otherwise it wouldn't be working
at all :-).

Tried that too, no joy (with all possible combinations of PCGI_ROOT and
PCGI_SetEnv, as I don't exactly understand its affect on Zope itself).

The dump from the REQUEST Session state shows (for both settings of
PCGI_SetEnv, plus some judicious editing):

URL:		http://localhost/cws/cws/Help/index_html
URL0:		http://localhost/cws/cws/Help/index_html
SERVER_URL:	http://localhost
REQUEST_URI:	/cws/Help
PATH_INFO:	/cws/Help

SiteRootPATH: changes (from /cws to /), so that's something.  :-)
From an environmental point of view, things appear OK (but what
would I know, I've only be using Zope for just over a week).  I'm
not sure how absolute_url() is constructing the full URL, but I guess
it would be from those above components (there doesn't appear to be
anything that defines the absolute hierarchy that I can find).

On a whim, I tried http://localhost/cws/manage, and the urls on that
page suffer the same problem too (eg, in the left hand frame there are
links of the form "http://localhost/cws/cws/Help/manage_workspace").
At least it's not just my DTML methods. :-)

Message-ID: <v04205508b4ed3dfc6467@[130.227.115.35]>

Hi,

Is it possible to use catalog to index ordinary html pages intelligent ?

If I have a html(dtml) file like:

<HTML>
<p id=title>
Are you Intelligent ?
</p>
<p id=author>
A. Einstein
</p>
</HTML>

I would like to index the title and the author id's, for which I could search.

Is it possible ??


Regards

   Well, let's me clarify a bit. PCGI_ROOT is the folder (or other object)
in Zope which will serve your requests. In your situation it is folder
"cws" in root folder.

   PCGI_SetEnv is *only an example* of how to set per-request environment
variable. Whatever variable you'll use and what value to set - it is up to
your configuration. In my example it is variable SiteRootPATH.

   This variable only works with SiteAccess. I use SiteAccess pretty
happily, and it solves all my virtual hosting needs, including rewriting of
BASE, absolute_url, etc.

   Without SiteAccess you'll get exactly what you get - additional path
components.

expand_all and collapse_all are all very well but I think Andy is after the same
thing that I gave up on. 

How can you expand or collapse a tree to a specific point, ie:

- make a particular subtree expanded 

- make sure a particular node in the tree in visible

The Zope DTML guide mentions the tree-s, tree-e and tree-c variables but it
doesn't explain how to use them. I haven't found any help anywhere on this.

Any ideas?

That's true, but that shouldn't hold us back indefinitely; some things are
can only be improved after a while if they're redesigned from scratch, 
otherwise the back-compatibility issues become too complicated. I don't know
if DTML is at this state though, and any new language proposal should be 
something to consider for the (very) long term.

But you lose some flexibility in defining table headers and footers;
you have to be careful your simple language becomes too rigid, making
too many assumptions.

Hm, what you're proposing is some higher level object (a product) that
does tables (in this case). That would in fact be rather neat.. Our simple
glue language could become extremely simple if we have sufficient higher
level components, and if it's easy enough to code up your own components.

I'm doing something like that for web forms in my ZFormulator product.

Okay, this kind of discussion probably belongs on another list, I agree. :)

I guess you could do it in XML-documents, that are
inherently more machine-readable than html..
Otherwise, storing title and author in properties would
do the trick for zcatalog..Not exactly what you ask for, but
as close as i can get with my skills..
I guess you could write a pythonmethod to extract title
and author from the html and store them in properties so
that they could be easily indexed..

Usin tree-s/c/e is going to be a bit problematic.

In my understanding those vars are built from the context of the node in the
tree, so if you add/remove anything to/from the tree then the tree-s/c/e
will change.

There doesn't seem to be anyway of going to a particular point in a tree
with any certainty.

I did this on one site for example, it's a prospectus for a college, the
tree is built from calls to a sql database.  Adding or removing records from
this database totally changed the tree-s/c/e vars that each node is
associated with.

I hope I'm wrong about that but I have a horrible feeling that I'm right.

Please someone prove me wrong.

actually I do have xml documents also but it is for an automatic 
system where the upload is done via webdav or ftp. So I need a way to 
upload Zope xmldocuments from a client.

I am not a Python programmer and would rather find a solution without 
doing some coding. But I have found the urls to find and update the 
index from the client. But now I need to upload xml documents to Zope 
AS xml documents. Is there an easy way to this ?

I don't know enough about Perl to judge this, but to me, there's
plenty of activity out there. Of course there could always be more,
but lots is happening.. We have _three_ independent implementations of
Python, for instance (Python, JPython and Vyper, and then there are
projects like Python2C).

Sure, it's not easy to do. I would debate that compiler/languages have
not thrived in the open source world, though. There seem to be
quite a few successful open source languages around.

[assessment of Vyper with which I agree]

That's the nature of discussion lists, almost. There are some prototype
implementations of type-checking systems for Python, though (I think
two or three independent ones, in fact).

Hm, but in my experience Python has been shown to be plenty fast enough
for the majority of applications. You're probably right though, and I
agree completely that a faster Python would be very nice.

I suggest you go discuss these things on comp.lang.python. :)

I don't miss switch. Functions are first class objects, and dictionaries
can be used instead of switch when necessary. Also, good object oriented
design tends to kill switch statements anyway.

I think the two loops are fine, though it would be nice to have the
current constructs to know about iterators. I believe Guido is
taking that into consideration. Also there's the list-comprehension
proposal which may help here. 

I don't think you'll see protected members any time soon.

I'm not sure what you mean with syntax for declaring mutability, though
it sounds interesting.

The types-sig is reaching consensus about optional static typing and
Guido does want to include that into the language in the future (beginnings
in 1.7, full implementation in Python 3000 aka Python 2). Interfaces are
being considered too, and Jim Fulton in fact has an interfaces proposal
out there (that may get used in Zope's code base).

I think using a unit testing framework can substitute for design by 
constract constructs myself.

Okay.

[snip code generator extension idea]

Something like that would definitely be neat. The hard part would be
in the translation process, of course. The other part is in the
interfacing with regular Python; do you allow your translated function
to refer to other Python objects? If you do, you're opening a can of
worms. If you don't, then it starts to look like the 'Swallow' subset
of Python I proposed once; a strict subset of Python with added full type
annotations, which is translatable into C or native machine code.

If you're starting such a project I want to hear more about it!

Not to mention indentation! Anyway, the people who keep bringing these
things up don't tend to be the Python nuts (mostly they're the newbies).

PCWeek did a shoot-out of various CMS packages about six months ago. 
They created a "scoresheet" that might be useful.  Unfortunately,
Vignette stood by their policy of not allowing their software to
reviewed, so it includes several other CMS packages.

This looks like the ZClass ID bug problem.

Message-ID: <4.2.0.58.20000309114320.01881df0@192.168.0.2>

Hello Darran,


building on Rik's previous answer, how about this:

   <dtml-call "REQUEST.set('myObjRef', _[desired_id])">

It tested OK with an Image object called "image" and located in the site root:

# Storing the image name in a variable
<dtml-call "REQUEST.set('desired_id','image')">

# Creating an object reference based on the variable
<dtml-call "REQUEST.set('myObjRef', _[desired_id])">

# Displaying the object title and size
<dtml-var "myObjRef.title">
<dtml-var "myObjRef.getSize()">

# Rendering the object if it's renderable. An image is.
<dtml-var myObjRef>

If it's not renderable, you'll end up with something like "<Folder instance 
at 01368880>" in the HTML page source code.

Does it work for you? If yes, you may want to add a FAQ Question and it's 
Answer on zdp.zope.org (hint, hint :-).


Cheers.

The answer in my case is both.
My test box is called "geezer" so initially it was set to "geezer". This
designation works with other IMAP tools (ishmail, Netscape). When this didn't
work I tried the FQDN: geezer.lab.jacku.com (My exposed FQDN is different due
to masking by the cable modem company.) This provided a similar error. Reading
the doc files I decided to leave the fields blank. This also generated an
error. (I don't remember at this point if it was the same exact error.) After
that failed I entered local host for both options and it worked. This became
the "last test" since its result was positive.

Hope this helps.

Hi Folks,

I sometimes et the strange and quite inconvenient problem that the
treeview of the manage interface gets spacing of a few cm's between the
(+) sign and the folders on any folder below the 2nd level. The result is
that the tree is quite wide. Does anybody else have this problem?

It seems to be happening if more than one or two branches are expanded,
but I haven't pinned the exact problem down yet. I use 2.1.4,
debian-packaged zope. Is this a known bug, can I help in some way in
tracking it down?

If there is a 'multiple select' on the property sheet with no value
initialized, you can get this error.  This seems to be a long-running
bug with multiple selects.  At the moment, it is important that the list
(or lines property) has values before creating the multiple select, and
then you must establish a value for any new multiple-select by selecting
one or more of the items in the multiple select as soon as you create
it.  I think the bug is in the collector, but I cannot be sure.

HI,

In the python interpreter I have done the following things:
>>>import sys, ZODB, ZODB.FileStorage
>>>db = ZODB.DB(ZODB.FileStorage('/usr/local/zope/zope214/Data.fs'))
>>>root=db.open().root()

Where 'Data.fs' is my Zope DB with a lot of stuff. Then I did the following
things:
>>>root.__dict__
>>>{}			#result of the previous "command"
>>>dir(root)
>>>[]			#result of the previous "command"
>>>vars(root)
>>>{'container' : {}}	#result of the previous "command"

I expected to find the stuff I have in my Zope DB. I double checked to look if
I didn't made a typo on the longname of my Data.fs file, but all seems ok. I
also saw that the modification time of Data.fs.lock and Data.fs.tmp were set to
the time I run db=ZODB.DB(....... so I guess I chose the right Data.fs file.

Can someone tell me where am I wrong?

Thanks

Hi,

When I have a form with a <textarea> field set to submit to an sql
method, ['it gets stored','like this']. How do I get around this? Do I
have to do some special formatting before submitting to the SQL method,
or is there something I must do in the SQL method declaration itself?
I'm using <dtml-sqlvar fieldname type=string> because this was the best
I could find in the documentation. Is there a type=lines? If there is,
someone please put it in the ZQR.

Another: I want a text holding ZClass for storing text pages. Deriving
from DTML Document or Method seems the obvious choice but I have an
issue with that: the content must be rendered thus:

<dtml-var standard_html_header>
<dtml-var raw newline_to_br>
<dtml-var standard_html_footer>

I suppose I have to override rendering for my ZClass and insert this
code. How do I do this?

This concept was kicked off by a specific need that led to discussions 
of polling, XML-RPC, Java RMI, JavaScript, and others that I can't recall. 
But, an unrelated need brought it home last night. The ZSchool project 
will at some point involve lot's of folks who won't be online constantly*, 
and suddenly Client Side Zope starts to look interesting. 

Keep in mind, it's Zope! For those of you who have sworn off all things 
Microsoft and have grown accustomed to the "joys" of compiling and 
tweaking Zope / Apache / etc. on all varieties of *n*x, you may not 
realize that getting Zope running on Windows takes about five minutes. 
Thats five minutes for a newbie. It's just a Windows "Install".

Now, if anyone mentioned Client Side Oracle Application Server, or Client 
Side Lotus Notes, we'd know they'd lost it. But Zope is actually small and 
nonintrusive enough to pull this off. Think about a world full of Zopelets, 
on all those nifty palm thingies. Your local WorldPilot could sync up with 
a central WorldPilot periodically, but you'd still have "all" your data
available 
while you're off-line*. Same with Xen Project Manager, zSchedule, etc. 
Of course that's just the beginning. A generation of new apps we've not 
dreamed of yet that could make this thing explode, when we figure out 
how to really exploit XML-RPC, and whatever comes next!

Later,

Hmmm....

Very interesting, I agree that installing Zope on Win* was very easy. The
problem I have is how to Sync stuff between my local Zope at home (no net
connection) and the 'real' Zope at work.

I currently do an export to a ZIP disk, and then an import back into the other
Zope from the disk. This makes a lot of things possible but only in very limited
circumstances:

You have to move *all* of Zope, or objects don't re-import back into the correct
place. Also, if an object changes on the 'real' Zope changes while I'm at home
and I import when I get back, the changes are lost as my import overwrites
whatever is there...not pretty.

Also, I can't do this trick with things like Squishdot postings, which is a
shame...

What would be nice is something like Lotus Notes replication when you import a
.zexp file; you get a replication conflict if both objects have changed, which
you can then sort out.

I'm not looking for the full-blown ZEO distributed object store, just a way to
periodically sync a set of selected objects (slightly more complex in the
squishdot case...) by exporting from one and re-importing (non-destructively)
into another.

Any ideas?

Hi,

  Is there any way in Zope to validate information
(news, new document) by third party before real
publishing.

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  How can I do this kind of things with Zope? Is it
possible?

  Any suggestion? links? help?

kindly,

Message-ID: <4.2.2.20000309104029.00be1b50@saladin.aisys.com>

I know that there have been several threads on this list concerning the way 
to pass arguments to a DTMLMethod.  I've done what I think is correct, yet 
my result is less than pleasing.

Here's what I have and what I'm doing.  Hopefully someone will identify 
what I'm doing wrong.

In my web sites root folder (aka /Foo), I have a DTMLMethod named 
"siteRoot".  It simply answers "Foo".

In a subfolder of Foo, I have a method named "linkFor".  The code for this 
method looks like this:

/<dtml-var siteRoot>/SomePage?option=<dtml-var optionValue>

In the same folder that contains the "linkFor" method, I have another 
method which wants to use the result of the "linkFor" method.  In this 
method there is a line which looks like this:

<a href="<dtml-var "linkFor(_, _.None, optionValue='some value')">">Some 
Text</a>

When this code gets executed, I get a "KeyError" on "siteRoot".  For some 
reason, when my linkFor method executes, it can't see the siteRoot method, 
even though the method exists in the parent folder.  What am I doing 
wrong?  Why can't linkFor see siteRoot?

Thanks.

I have never seen the Python interpreter crash in any way, nor have I heard
of it doing so. I havent seen this, but my partner tells me he as seen the
Perl interpreter crash. I have seen the Java JVM crash many many times. Some
of my Python code has been running 24/7 for the last 18 months.

I would say that, as languages or interpreters, Python and Perl are equally
and extremely stable. As tools for developing software, Python's object
oriented foundation is conducive to the building of more stable _systems_
that Perl. This could be because of the language itself, or because of the
programmers it attracts.

Most of the Perl programmers I have met are, frankly, obscuritan mess-heads.
The concept of structured programming is somewhat anathema to the Perl
programmer. I looked over the shoulder of one Perl programmer we had hired,
who was having trouble with a database import problem for several weeks.
This Perl programmer had written 6 pages of perl code without actually using
_any_ indentation. The program was full of nested loops and she was having a
difficult time debugging her code. Without knowing any Perl, I cleaned up
the indentation, fixed a few glaring problems, and handed it back to her.
She had the problem solved at the end of the day.

It comes down to this: It is hard to write a program in Python that another
Python programmer (or the same programer several months later) wont
understand. It is easy to write a program in Perl that another Perl
programmer wont understand.

As for the outside consultant. Ask them what makes them feel that Python is
less stable than Perl, and what exactly that means.

   There are mnay ways you can do it. Publish it in some hidden location
and later move it into public area. Use Versions. Develop your own
mechanism for publishing...

  Is there any way in Zope to validate information

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  Any suggestion? links? help?


[RH] There are several ways to accomplish this:
You could put the document in an 'incoming' folder and make a reviewer move
it to the publishing location (this also allows for letting the reviewer add
keywords/categories etc).

If the uploaded document goes directly to the documentation where it is
published, you could give it a property called 'approved'; reviewer invokes
dtml method which sets the approved property to 1. The document is not shown
unless the ' approved' == 1.
[untested simplistic dtml]

<dtml-unless "approved==0">
   <dtml-var <document>>
</dtml-unless>

I believe the Squishdot product
(http://www.zope.org/Members/butchland/Squishdot) allows for something like
this.

A third (more sophisticated) possibility is to combine the two approaches by
using the Catalog, more or less like the Zope site does:
contributions by members are submitted for approval to the Zope site
administrators, who then add them to the site's catalog. Then they are
available in pages that use the catalog for their contents (like the howto
pages, the products pages etc). In your case reviewers could also add
keywords/categories etc to the document before it is cataloged and the
catalog may index these. I do not think the Zope site approach is available
for the public, but it shouldn't be too difficult to implement it.

A related product is ZDP tools (http://www.zope.org/Members/roeder), which
does not exactly do this but may be a source of inspiration for workflow
management. Another workflow system in Zope is Xen (I do not have the URL
handy right now), but this may be overkill for your needs.

Hey James,

Just in my experience I have never had a problem with the stability of
either Python or Zope. I have set them both up on multiple servers (RH 6.0,
6.1) and been pounding away at them for months now. Python 1.5.2 has been
out of awhile (a year?) and Zope releases are certainly stable. In fact,
having been using Python for web CGI scripting for 4 years now I have never
had a problem with the stability of it as a language (run it on NT, Mac,
Linux and Solaris boxes). I usually just build it and let it leave it, never
needing to look back till I am ready to update it.

2 folders are next to each other, one is called test1 the other test2. They
are within the same Home folder, but one is not within the other. Can an
index_html document in test1 grab a dtml-var from test2? How is this done?
In html i would simply write ../test2/dtml-var. This does not work in Zope.

Message-ID: <v04220803b4ed7c0e4906@[192.168.0.16]>

I can confirm and reproduce this problem, and on a totally different 
architecture - Red Hat Linux system with Zope 2.1.4. Here's a snippet 
from my /var/log/messages file:

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- -
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782


Notice that the timestamp from the syslog facility is the correct 
local time, March 8 10:14:18, which is Pacific Standard Time. On the 
very same line, the timestamp passed to the syslog from Z2 is in GMT, 
08/Mar/2000:18:14:18 -0700. My guess is that Zope isn't picking up 
the $TZ environment variable. What I don't get is why it's showing 
GMT as 18:14:18 -0700. That would imply a local time of 11:14:18. I 
think it should be 18:14:18 -0800 right now, and -0700 during 
daylight savings time. Two, two, two bugs in one!

I think you are safe in classifying this statement as FUD.  I've been
using Python (outside of Zope) for five years.  I even had a non-trivial
accounting system that my business depended on running in Python.
A bad design decision on my part led to some real problems with memory
size and CPU use of the resulting program, but Python never crashed
no matter how much data I tried to shoehorn into my badly designed
system.  Python is rock solid.

So does KM|Netnews (available on the products page on zope.org).
If it doesn't meet your publishing needs, you might want to look
at its code to see an example of a way to do it.  (I haven't looked

I have a simple two field table in MySQL, "whowhat", that pulls a user id
from one table, and a class code from another.  (It tells you "who" has
"what" classes)

I , being somewhat new to python & Zope, am having the darndest time trying
to do a simple external method to do a count of how many times the class
"so-and-so" is in the table. (That way, I know how many people have
signed-up, and how close I am to the class max.)  I have tried different
searches.  I have an SQL Method that does:

select * from whowhat

And I also have one that does:

...
select * from whatwhat where classcode = <dtml-sqlvar class_name type=nb>

I've been trying to create an External Method, but I just can't seem to get
it to work. (yes, in the Extentions directory)

I need to try to stay away from doing a "select count(classcode)..." in an
SQL Method if I can.

Any help to this tormented soul would be greatly appreciated.

  Currently I have no problem view the HTML tables of the calendar or

the tables of the calendar.

Currently the variables for the date, whether the object has a property,
and the value of that property are registed just like the <dtml-calendar>
How-to.

<dtml-let d="date.Date()"
          hasdate="hasProperty(d)"

The 'd="date.Date()"' does what it is supposed to. (make d equal to
something like 2000/01/17). I checked the hasdate variable and found that
it was equal to a 0 (1 if true, 0 if false, of course).

The properties are kept on the folder, where the calendar method is. I
added a property via the method for doing such and went back and checked
the folder to see if it had a property on it. Yes it did... in this format.

Tree Structure:    /diis
                     /calendar (contains the properties)
                       index_html (displays the calendar)
                       /updatecalendar
                         index_html (used for editing the properties)
2000/01/17 This is the 17th day of January.

Yet, hasdate was equally 0 (false) therefore the 'dprop' value could not be
set.

I guess my question is this:
  If the folder containing the calendar method has properties on it which
are   to be read into the tables of the calendar, does this mean that
'hasProperty(d)' is not being read off the folder and is looking at some
other object for the value?  

If that is not the question can someone please point something out to me
that I am doing wrong...

All help is extremly appreciated.

Best regards, 

Mark J. Stahl

The testamonials continue...

I wrote a perl app a few years ago for a customer, about 10,000 lines.
It produces a book in postscript from a database of info. They run it
once a week. It crashed at random. After 6 months, I couldn't read my
own code, comments or not. I ended up rewriting in Python and it has run
without a hitch for about 2 years AND I can still read and understand
the code. I hesitate to write a thing in perl anymore, and if I am
forced to, won't support it. I've had Zope and numerous other programs
in Python running without one crash EVER! Believe it!

It really depends on how bad your intentions are. Could you use
subclassing? Or do you want to add methods dynamically after instance
creation?

I am not sure what you mean by dtml-var but I assume you want to access
some attribute in test2. You can make test2 attributes accessible in test1
by:

<dtml-with test2>
tarari tarara
</dtml-with>

Message-ID: <20000309110821.A2683@devware.com>

I have seen a couple of people mention zope lockups on here before and
I haven't seen any myself until just recently.  (I have zope on about
5-6 machines and this is the first time I've seen this happen)
Anyway, how can I diagnose this problem?  So far I have only seen it
happen twice, but it was twice in the last 24 hours, and I'm getting
ready to roll out this app to some users.  I'm concerned!  Anyone have
any suggestions?

Symptoms are basically that it just stops responding.  The web browser
seems to connect, but it never completes the connection.  Right now I
have it running in debug mode to see if I can catch whatever it is
with some console logging.  This is on an NT Server running NT 4.0

I believe you have to supply the (_.None, _)
parameter for the index_html method to work.

You are ALMOST ALWAYS better off using the
<dtml-with ...> tag, something like

<dtml-with test2>
  <dtml-var a_something_inside_test2>
</dtml-with>

Or in the more general case of many layers

<dtml-with "FolderA.SubFolderB.SubSubFolderC.test2">
  <dtml-var methodA>
</dtml-with>

This pushes test2 onto the namespace stack. So
your methodA can still access objects inside
the SubSubFolderC.

------------------------------------------------

Use the dotted notation, e.g:

<dtml-var "F1.SF2.methodA(_.None, _)">

only if you don't need any objects from the
subfolder F1.SF2 during the call. Most of the
times, this is not what you want.

In this case subclassing won't work and I'm not needing to do this

Subject: [Zope] Finding crash information
Message-ID: <m37lfcawfm.fsf@wacko.pdx.net>

I'm having a serious problem with my Zope server running in
production.

Platform: RedHat Linux 6 (2.2.12-20 kernel)
          Python 1.5.2
          Zope 2.1.4
          starting with: python z2.py
                         as root/nobody on port 80 straight ZServer


Under load (not too heavy, but busy) the Zope process SILENTLY stops.
I get no traceback info anywhere that I can see.  Nothing to
stdout/stderr, nothing in Z2.log.

If I start as: python z2.py -Z '' to prevent the fork and detach I
still get no message when the crash occurs.  

I can't run this in DEBUG mode because I'm using GUF cookie mode to
authenticate and the login screen ends up showing an exception error
(by design?)

If anyone can tell me how to run in DEBUG mode but make GUF still hide
the exception error that would be a big help.

If anyone can help me keep this server from crashing every forty-five
minutes I'll buy 'em a beer next time they're in Portland.

-Jon

BTW, the site is very non-exotic.  GenericUserFolder with a lot of
static content and one ZCatalog w/CatalogAware ZClass.

Let's say in Zope you have SQLMethod whowhat and SQLMethod whatwhat.  In
your external method you should simply be able to do:

def countWhoWhat(self):
  return len(self.whowhat())

def countWhatWhat(self, class):
  return len(self.whatwhat(class=class))

These should return the result count for each SQLMethod.

Now, I now I can do this using JavaScript on client side, by doing something

So is it possible to do this without JavaScript ?

I never had any problems, but then again, I'm not sure I've ever done this with
index_html, or in quite the way you describe.

Done it lots with calls to SQL methods and other DTML methods, but I don't think
they reference other objects themselves...

Hi all,

I have built a trivial ZClass : CD (from CDProduct, from the guides).

I try to add a DTML Method "render_short".
This method would render the CD Instance on one short line.

My ZClass has simple attributes (artist : string, title : string,
description : text)

I would like to be able to write this simple "render_short" DTML method like
:


Artist : <dtml-var artist>
Title : <dtml-var title>
Descr : <dtml-var description fmt="structured-text" newline_to_br>

But when I insert a <dtml_var myCDInstance> in my index_html, I got a
exception :

Error Type: KeyError
Error Value: artist

There is no typo in my code...
How can I access to my ZClass instance attribute from inside its methods ?


Please help me :)

Olivier

Is this a pure Python question? (Zope External methods
are VERY different from Python methods, that's why I need
to ask.)

If you are talking about pure Python, sure, you can add
class members (data or method) at any time.

-----------------------------
File A.py:

class Chicken:
    def __init__(self, size):
        self.size = size
--------------------------------
File B.py:

import A

def getSize(self):
    return self.size

A.Chicken.getSize = getSize

b = A.Chicken(123)
print b.getSize() # prints 123
--------------------------------

If you are using Zope, you must store your
classes where they can be accessed by
Python. Usually /lib/python/Shared/Local
is a good place, make sure to add the
__init__.py file inside the folder. You
then refer to the class as Shared.Local.Chicken.

What a coincidence.
 I have exactly the same problem. One site with GUF and a CatalogAware
ZClass which silently stops after some time. No errors.

The problem with GUF and DEBUG mode relates to lost filedescriptors.
Someone posted an explanation (maybe a patch too). You might be able to
locate it by doing a search on the list.

Please let me know if you find something out.

I agree. The guides need to be complete, error free, and chock full of
examples.

Hmm. I wasn't aware of the old style syntax, that should definitely be
updated. I also agree that we need to review guides and update examples
to use the latest and simplest techniques. This is especially true for
DTML.

I agree. We do have categories for How-Tos but they are not currently
sorted on Zope.org by category. Probably the categories could be
improved, too.

Again I agree. How-Tos should also provide some feedback system to allow
readers to comment on How-To and point out problems.

Thanks for your excellent ideas!

I'm a little pzzled about :

"objects don't re-import back into the correct place"

I haven't had any trouble exporting / Importing enitre branches. Of course,
I delete the branch to be overwritten first, or at least move, or rename
it. Is that how you're doing this?

XML export may come into play here, since the XML version is parsable. I'm
not aware of any existing Zope tool for dunning a comparison process.

One point that I think is still evolving is a clear set of guidelines
regarding what data is held in Zope, and what should be in other formats,
such as Gadfly. As long as we diligently keep DTML doing templating, and
avoid mixing tabular data and static content in with ZODB objects, it
should be fairly straightforward to do Zope Exports of the Zope Framework,
and file copies, or native exports of data in other "backends".

Mailman has no "global" username/password directory -- every email
address in every list has a password associated with it, that's all.
Known design flaw, and Barry Warsaw (the Mailman maintainer) has
threatened to fix it.

I think this *might* fix the problem you guys are having.  Although we
aren't using GUF or CatalogAware objects, we discovered this on a system
that was under pretty heavy load.

Hello,

Has someone a small code-snipet or something like that which explains the

Hello WorldPilot Users,

There's a new WorldPilot 1.0.3 maintenance release available,
that addresses some of the interoperability issues.
Check out
http://www.worldpilot.org
or
ftp://demo.worldpilot.com/pub/worldpilot/worldpilot-release-1.0.3.tar 


Calendar Problems:
For everybody who had Timezone troubles with the WorldPilot
Calendar, this release should hopefully work for you now.

Please send us your positive or negative feedback to
mailto:feedback@worldpilot.org
so that we know if it now works around the globe :-)


UW IMAP users:
And for all the (UW-) IMAP users there is now a IMAPHACK.py 
file located in the WorldPilot Product directory. Here you
can set the Base IMAP directory (e.g. Mail or INBOX) and
you can choose to only list subscribed folders (but you'll currently
need to subscribe them with a seperate client).

Thanks for all the tips and suggestions! I hope WorldPilot will 
soon operate with most of the remaining other IMAP servers, too.
We're still working on some of those other tracebacks that got
sent in.

Cheers,
Ryan

That's OK. Please do the experiment yourself, it
only takes 3 minutes or less to verify it. You
don't need to trust my words. Trust the result
you see with your own eyes. :)

A good many people in the list have said this
repeatedly: try it first, before posting. I think
it's a little bit too much to ask everyone to
do that every time, but this is a responsible
mailing list and not some flame-loaded newsgroup.
So, when it takes only a few minutes to confirm
something simple, why not try it first?

Hung Jung

Message-ID: <20000309142919.D183689@isc.upenn.edu>

hi: I'm trying to use the BasicAuth example in the "XML-RPC How To"

http://www.zope.org/Members/Amos/XML-RPC


I keep getting the Zope error when creaing the External Method:

Zope has encountered an error while publishing this resource. 

            Error Type: SyntaxError
            Error Value: invalid syntax

--------

I've just cut and pasted this from the webpage, only removed extra padding spaces, and spliced the one big
line back together:
 h.putheader("AUTHORIZATION", "Basic %s" % string.replace(encodestring("%s:%s" % (self.username,
self.password)),"\012", ""))



The code defines a class and a def:


---------------
class BasicAuthTransport(xmlrpclib.Transport):
    def __init__(self, username=xxxx, password=xxxx):
        self.username=username
        self.password=password

    def request(self, host, handler, request_body):
        # issue XML-RPC request

----------------
In the Add External method page, where you enter in the Function name I've tried:

request
BasicAuthTransport
BasicAuthTransport.request
request.BasicAuthTransport

Which is the right one? it want's the Function 'request', right?

So, the syntax error must be something in the script.

Any help would be appreciated.

You *can* actually get Python to crash if you're intentionally mean to
it.  All the ways I know of involve tricking it into blowing the C
stack, like:

	class C:
	    pass

	C.__init__ = C; C()

Not that you could expect that construct to do anything useful anyway;
you wouldn't ever see code like that in an application.

You have to go out of your way doing really bizarre stuff get it to crash.
It's very stable otherwise.  :-)

Message-ID: <38C8037B.8AD7F12C@digicool.com>

First of all, what you want can be done, but it is not that easy.  There
are a couple problems with your design goal, some Zope's, some yours. 
Luckily, the alternative is *very* easy ('very' being a relative term
here, basicly it means you don't have to re-engineer Zope).

You probably know this, but when Zope is tooling down through objects is
traverses them according to various rules.  First, it does something
special (we'll get to that), then it tries to find the next object in
line by just seeing if the next object is a subobject of the current
(getattr).  If that fails it tries to get the next objects as a sub-item
of the current (getitem).  If that fails, then it gives you a 404
telling you it couldn't find the next element in the URL you provided
(you being the client).

The special thing it does is it calls __bobo_traverse__.  This is a
special method.  So you override the root level folder's
__bobo_traverse__ to see if your 'virtual folder' is a user and then
proceed from there.  This is the problem: 1) You can't override the root
level folder, because it's not a folder, really, it's the entire Zope
application and 2) we override it allready so we beat you to it.

Further, although simple, I think you will come to hate having all of
your users in your root folder namespace.  Generally, you want to keep
this namespace as unclutered as possible for many reasons.  One good
reason is that everything in the root folder is acquireable by
everything else, so it's 'prime real estate' in Zope.  Another is what
if one of your users wants to be named index_html?  Or rss?  Your
__bobo_traverse__ method will either have to know all the special names
you want priority on and do the users second, or whatever.  Complex. 
Prone to error.

What you really want is this:

mysite.com/Users/Fred/rss

So you need a special object, in this case instanciated with the id
'Users', that takes the next argument in line as a key into a database,
and doesn't break acquisition paths along the way and lets you do this
fancy URL manipulation.  This special object can have a much simpler
__bobo_traverse__ method, because it's not also trying to deal with
other objects in the same namespace, the 'Users' namespace is dedicated
solely to serving these virtual path elements.  This special object
should also be very generic, not database specific, and should be
programmable directly with various SQL code to execute the query you
want.

This special object allready exists and does everthing you want to do,
it's called a ZSQL Method.  ZSQL Methods can accept arguments in the
URL, and maintain acquisition so you can apply results to 'higher'
objects.  In fact, you can even chain ZSQL methods together to do
multiple database look ups.  Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.

Nifty eh?

Exactly, absolute_url tools up through the various aq_inner wrappers to
build an objects absolute_url.  Sorry, I don't know anything about fcgi.

Hi Andy,

In my MySQLdb directory, the Setup.in file contains the following:

_mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt

Note that this does NOT point to the location of the Python.h file, as you
suggested it should (below)

I've just finished recompiling and installing Python, Python-devel, MySQL,
MySQL-devel; after each step, I tried to run the build.py script and each
time I get the following error:

 Traceback (innermost last):
    File "build.py", line 14, in ?
      import MySQLdb
    File "MySQLdb.py", line 19, in ?
      from _mysql inport *
  ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

I even tried installing just MySQLDA and that failed, too.

<EXTREME FRUSTRATION>All I want is to be able to connect to a MySQL DB from
Zope.</EXTREME FRUSTRATION>

Any assistance is greatly appreciated!

Eric.

<guess>

You must still use medusa (ZServer, in this case) even if you want to
use PCGI (which is what Zap uses).  ZServer listens to many protocols,
like HTTP, FTP, and PCGI.  If you don't use medusa, PCGI will try to
fire up Zope the OLD way, and it will probably work but it's not the
right way.  The problem is, now your process environment has the wrong
LD_LIBRARY_PATH (and a whole slew of other problems related to running
Zope the old way, like no concurrency) and cannot find your Oracle
dynamic libraries.

Run ZServer first.  Then Zap.  Then it should work.

Yes, the Catalog can be used programatically from DTML and Python.  You
will have to implement your own parser (look at the standard htmllib in
python) that feeds the parsed attributes into the Catalog.

Does it do it out of the box?  No.

I'm sure this is simpler than I'm making it out to be, but here goes...

I'm looking at using SquishDot as a 'home page' for our Intranet, but can't
seem to make its index_html show up as the default document.  What I'd like
is for a user to be able to point his or her browser at
"http://www.mysite.com" and get SquishDot, outisde of setting up a redirect.
What's the easiest way to do this?

I looked at this once and my mind got lost in a sea of table tags.  If
you pin it down conclusivly as a bug, we'll fix it.  But it never
happens on Exploder, and I haven't seen it on Mozilla yet, so I'm
betting it's a Netscrapism.

Yeah, and blue people are dumber than green people and orange people are

The perfect counter argument is.  "Prove it."  If this person asks *you*
to prove it, show them the Lawrence Livermore National Labs, the
mems-exchange (all multi-million $+ scientific establishments), Jon
Udell articles, etc etc.  There is a mountain of evidence on your side
and nothing on his/hers.

Subject: [Zope] newbie closing in on Zope / IIS
Message-ID: <NDBBKGBPJMFODAAFNMKEOEANCAAA.mduvall_22030@yahoo.com>

I think my Zope is working with IIS, but some of the icons in the Management
screen can't be found.

For example, the Control Panel icon is fine:
http://localhost/scripts/zope.pcgi/p_/ControlPanel_icon is indeed there.
This looks like an object reference, right?

The Folder Icon:
http://localhost/scripts/zope.pcgi/misc_/OFSP/Folder_icon.gif , however, is
not. The same is true for the User Folder and DTML Method gifs (and a few
others). In the Zope install, the gifs are in the
root\lib\python\Products\OFSP\images folder.

I'd welcome any suggestions. It's a minor problem, but it's a bit of an
eyesore. Thank you!

Regards,
Mitch Duvall
mduvall@webversant.com

P.S. There was a thread about Zope / IIS last month. I was in a similar
situation in which all I could see when I got to step 6 in Brian Hooper's
how-to was the "Welcome to Zope" page. The change that got me into the
Management screen and logged on was to use the default 401.5 error message
for IIS' "Default Web Site". My thanks to all who've helped out.

If the debug log in incomprehensable (it might be) post the tail end of

Not without javascript, clicking on a lick causes a GET.  Clicking on a
form button causes a POST.  I could be wrong, but I'm pretty certain
that's the convention.

Subject: [Zope] ZClass, Base Classes and logic (QUEST)
Message-ID: <00030915401200.06239@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

Most of the time when someone complains about DTML syntax or the learning curve
and so on, the answer is we should code our logic in python if we know this
language. That's what I am trying to do because I love Python.

However, many times I don't know how to import my logic in Zope. 

example:

I wrote a very simple module MyTest.py:
##################################
class SuperClass:
	def __init__(self):
		self.a='This is a in SuperClass'

class MyClass(SuperClass):
	def __init__(self):
		SuperClass.__init__(self)
		self.b='This is b in Myclass'
##################################
In the python interpreter I do the following things:
>>>import MyTest
>>>import MyTest.MyClass
>>>t=MyTest.MyClass.MyClass()
>>>t.a
'This is a in SuperClass'
>>>t.b
'This is b in Myclass'

That's what I expected. Now I intall the package in zope.  I make a ZClass which
only Base class in MyClass. Its metatype is MyClassClass, so it appears on the
popup menu near the Add button.

But when I try to add an instance I get the following message:

Error Type: TypeError
          Error Value: unbound method must be called with class instance 1st
          argument

I guess that the problem is the line
	SuperClass.__init__(self)

==>however I don't understand why it works fine with the python interpreter and
why not in Zope.

Others behaviors of Zope:
suppose i add the following line in the MyClass __init__ function:
self.d='I am d'

No problem when I run it with the interpreter:
	>>>t.d
	'I am d'

In zope:
	<dtml-var "MyClassInstance.d"> 
renders:
	Error Type: AttributeError
          	Error Value: d

I get the right value of d only with the new instances of MyClass. On the other
hand if MyClass has a property sheet, all the instances are updated if change
the property sheet.

==>So again, why these differences in the behavior of ZClass instances depending
of which part we modify (the python Base Class or the Zope ZClass)?

I really love Zope but I prefer code in python. However I hit often the wall
when I try to put the pieces together. I think that speaking about
documentation : clear API docs would be, for me the most important.
What behavior could I expect from the differents parts of Zope. 

Example of docs I find useful with other 'languages':
Python Library Reference
Java API documentation

What's the traceback embedded in the HTML source of the error page?

It will point you directly to where the syntax error is.

Nope -- that doesn't do it.  It does raise a lot more questions,
though.  :-(

Recap: I'm working in a near-fresh Zope 2.1.4 installation.
Everything's in the root folder.  Two objects of interest:

  my_dtml_meth -
    a DTML method that shows the document title, ID, etc.  (because I'm
    curious); the title for this object is "Test DTML Method"

  my_xm -
    an external method that does nothing except attempt to set the
    document title and call my_dtml_meth; the title for this object is
    "External Method: Call DTML Method"

The code has changed a bit since my last post, so here we go again.
Here's my_dtml_meth (the DTML Method):

  <dtml-var standard_html_header>
  id:             <b><dtml-var id></b><br>
  title:          <b><dtml-var title></b><br>
  document_title: <b><dtml-var document_title></b><br>
  document_id:    <b><dtml-var document_id></b><br>
  title_or_id:    <b><dtml-var title_or_id></b><br>
  title_and_id:   <b><dtml-var title_and_id></b><br>
  <dtml-var standard_html_footer>

And here's my_xm (the external method that calls my_dtml_meth):

  def my_xm (self, REQUEST=None, RESPONSE=None):
      RESPONSE.setHeader ('Title', "Title from External Method (try 1)")
      REQUEST.set ('title', "Title from External Method (try 2)")
      return self.my_dtml_meth (self, REQUEST, RESPONSE)

Note that I'm trying two attempts to set the title; my original guess
based on reading the HTTPResponse code, and Michel's suggestion.

Here's what happens when I call these things.  First, my_dtml_meth, as
rendered in Netscape:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Ie. it's possible to get the object's title using "document_title" --
but the standard_html_header uses "title", so my browser's window
advertises this document as "Zope".  Ugh.  Guess I could fix
standard_html_header, but why does it work this way?

Now I call my_xm, hoping against hope that it will override the title of
my_dtml_meth; here's what I get:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Hmmm... identical.  Ie. neither attempt to set the title in my_xm had
any affect whatsoever.  In fact, I just used a command-line HTTP client
to diff the headers and body, and they compare byte-for-byte.

So: no dice.  Better ideas, anyone?

(I think I've learned enough to solve my problem, though: use
document_title rather than title in standard_html_header, and make sure
the DTML method in question has a meaningful title.  But I'm still
curious why things work the way they do.)

Ha, ha!  Silly me...

Internally, my server is known as 'www.waco.ct' and I set up SiteAccess so
that every request containing 'waco' and 'ct' is redirected to the SquishDot
folder.  Of course, this means that I instantly can't get back to the root
folder for any reason.  To fix it, I shut down Zope, removed the SiteAccess
product manually, restarted, and got rid of the offending code.

I offer this as a warning to others interested in SiteAccess--the product
works great, but think a little before you set things up, lest you fall into
the same trap I did.

Thanks. That was the problem. I persevered in my mistake because I saw

I try to understand the ZODB because i want to process some data in my ZODB

My main achievement with Zope is part of the MEMS Exchange mentioned by
Michel:

   http://www.mems-exchange.org/z/process/builder/

This is a tool for people to specify the process sequence to fabricate a
MEMS device (= micro-electro-mechanical system, aka micromachine or
microsystem).  They're typically fabricated using the same techniques as
IC fab, but in much more varied ways -- hence the need for people to
specify custom fabrication sequences.  For non-specialists, most of this
tool is meaningless, but it's an interesting demo of how much user
interface you can get away with on the web using something like Zope.

For the record, before we started playing with Zope, I was convinced
that complex user interfaces on the web were all-but-impossible.  Thanks
to Zope, I now believe that complex user interfaces on the web are
merely very difficult.  

We have found no bugs in Python developing this system; we certainly
have our share of gripes with Zope, but I think we've only seen two bugs
that really affected the reliability of our web site.  The first bug was
when Zope 2.1 came out, and we made the mistake of going straight from a
single-threaded, PCGI, Zope 2.0 installation to multi-threaded, FastCGI,
Zope 2.1; things got really flaky.  I think we're now running
single-threaded, PCGI, Zope 2.1.4 and things are peachy.  We really need
to step gingerly back into multi-threaded/FastCGI territory to see how
it behaves.  The other bug was a nasty ref-counting problem deep in the
bowels of mxODBC, so can't really be blamed on Zope.

I've named the python script ba.py.


Is using 'request' proper for the 'Function name?'

If it's the same error we were seeing, then it isn't that Zope crashes,
it hangs, becomes non-responsive.  It's not spinning, it's just sitting
there not answering.  The reason why (in our case) is because of an
uncaptured exception in the medusa code.  Whenever medusa encounters an
uncaptured exception in a thread, it closes it down.  Well, it was
encountering an uncaptured exception in the main listening thread, so it
shut it down... now Zope isn't listening anymore... so it just sits
there.

If you want debug output without using debug mode, add this code to your
start script (reverse the slashes for Win32, of course):

STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE

Debug information will get stored in event.log.

Ok, my syntax error was that I was replacing the username and password with strings and not putting them in

That's fixed.

But I'm still having an error now.

True enough, though I'd have liked to see more, and I'd have liked to
contribute more, too, which is to say, I'd like to contribute at *all*
-- no time for that at the moment, however. Ironically, I'm too busy
using it to improve it.

I find it ironic that JPython is even *slower* than CPython. Curious --
is anybody using it for anything worthwhile?

I'm not disputing the success of these languages. Perl, Python, PHP,
Pike -- they're all quite successful at what they aim to be (*). But
people tend to use languages rather than contributing to their
development. You can't just evolve a language indiscriminantly, which is
why we have Guido and Larry, the benevolent dictators. You can't just
go, "oh, and I added iterated loops today". Every damn little feature
requires at least some kind of ratification process. Languages are much
more susceptible to breaking.

(*) Except possibly Pike. I'm ashamed to say it, but I find myself oddly
attracted to this language, if mostly because of its speed and
interesting resemblance to C. Pike is a good example of "how to make a
powerful language/interpreter system that's also very fast". Pike has
had a type system from the outset, which is a definite edge over Python.

Where?

The type system SIG has a funny intro: "Recently, the types SIG has come
under attack for inactivity, and in response Paul Prescod has offered to
guide the SIG towards accomplishing a single specific goal: to develop
an optional static typing system for Python. The December 1999 archives
of the SIG show the discussion that lead to this decision."

Reading this stuff now. It's interesting. I hope they get it right.
Maybe I'll chip in.

What's interesting about Dylan is that, because it relies on static
information such as type hints and class/method relationships to be
efficient, the developers of Functional Developer (formely Harlequin
Dylan) are facing a design problem related to how they compile programs.
They've actually put all of the various libraries into shared DLLs.
Unfortunately, this means they lose the benefits of the optimizations
that can be made through the use of static compiler information. When
you load up the [latest beta of the] Developer IDE and compile a
program, it consumes a whopping 45MB of RAM. And it's damn slow. The
absence of such optimizations is one reason for this hogging tendency.
So they're planning on providing a "whole program delivery" option
whereby all libraries would be statically linked.

I have several apps where I would rather use Python, but where speed is
so significant that I would either end up writing a lot of the code in
C++ for speed (which is painful due to the lack of integration between
the two languages -- Python classes can't inherit from stuff in the C++
extension, for example).

I also have a database-centric Zope app that causing me headache. The
ZODB is *way* too immature to replace a database right now -- fine for
the kind of stuff that runs on zope.org, not for us. ream

I would like to that all of you who responded to my question concerning 
Zope/Python stability.  It turns out that this information won't be helpful 
for this project (the 'consultant' is probably going to go a different 
direction), but hopefully I can use this information to overcome objections

Pardon me for sending off another email in mid-stride. Damn cat :-)

Let me finish the last sentence first: I also have a database-centric
Zope app that causing me headache. The ZODB is *way* too immature to
replace a database right now -- fine for the kind of stuff that runs on
zope.org, not for us. We're actually looking at alternative app servers
and solutions (such as hardwired C++ CGI code) right now. It's a shame,
and I'm fighting it, but we might end up with something like Dynamo.

I don't necessarily say they're _my_ problems, but some people think
they are, and that counts. I don't miss "switch" myself, although I do
miss a kind of enumerated type.

I remember sitting down with Python for the first time create a simple
CGI type thing, and found that I could just do

  def DoSomething(): ...
  def DoSomethingElse(): ...

  DoSomething(eval('Do' + Args['cmd']))

and then call up the CGI using a query string such as
/cgi-bin/foo.py?cmd=Something. Wonderful, and better than any kind of
RTTI.

The list comprehension syntax is cute, but not, I think, so clever.
Perhaps it'll prove to be a nice feature, even a successful one, but
personally I doubt, even with the knowledge in the back of my head of
how this stuff works, that I would instinctively grasp for a
list-comprehension expression as naturally as I grab for, say, a "while"
loop. My head is just not wired that way, and I think the syntax looks
positively alien for Python -- it's not "pythonic".
 
> I don't think you'll see protected members any time soon.

I think Zope's source code is one huge, glowing argument in favour of
having protected members.

I don't particularly take to the idea of a having
mutability/immulatibility property burned into the type itself.

Tuples are immutable, dicts and lists are mutable. Why? Because Guido
says so. Jon Udell, I think it was, has argued that tuples are currently
a redundant element in the language. Why have two kinds of lists? It
just confuses people.

A syntax for declaring the mutability of types would be helpful in
clearing out this mess. For example, you should be able to declare a
dict to be immutable when passed to a certain function call -- ie.,
forcing a copy. Python has no "out" parameter, only "in" parameters that
are mutable depending on the type of the object passed. The syntax I'm
alluding to would effectively give you both "out" and "const"
parameters.

I haven't thought it through. I just think it was potential. Why
shouldn't the translated function refer to other objects? The function
would essentially just constitute native calls to the Py* APIs -- in
effect, a translated function would summarize the runtime calls made by
the interpreter during normal execution. Therefore, non-translated
Python code could just as easily refer to translated code (within a
"translated module", which would be a special object), because the
translator module would construct the necessary proxy object to forward
external calls to the inner code. Or something. ;-)

Thanks Mike,

You are right, root/Users/<usernames> makes more sense than
root/<usernames>.

I looked at what you said, went away and read ZSQL Methods user guide
(again).

Now I'm back.....

>>
 Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.
<<

So my Zope folder layout looks like this :

root
   index_html (default)
   Users (SQL method)
   Flavor (SQL method)

I assume I would also need a DTML Document called "rss" because the SQL
methods can't actually deliver any content to the client browser?

So, if you would be so kind, lead me through how Zope works on this call :

mysite.com/Users/Fred/Flavor/Cherry/rss

Zope starts to traverse the call from left-to-right?

finds "Users", its a SQL method which takes an argument, aha! the argument
is "Fred",

[Does Zope now run the Users SQL with that argument?]

ok, what's left : "Flavor", okay, I have a "Flavor" SQL method here and that
takes an argument too, "Cherry" is that argument.

Finally, Zope finds "rss", if this is a DTMLDocument or something "servable"
it runs it and returns it to the client?

If "rss" wasn't there it grabs the index_html page and serves that?

=======

Thanks for your help.

Like many others I suspect, I see Zope through a cloud. Sometimes I see the
outlines of it and it glimmers! But I just can't grasp a picture of the
whole.

Ah yes, I didn't realize it was in an external method.  External methods
mask the exact error information.

Just import ba.py into a python interpreter *without* Zope and it will
tell you where the error is.

Subject: [Zope] how to tell if displayed in a frame
Message-ID: <38C82A33.B333748A@open.ac.uk>

I have a page that sometimes gets displayed in a frame
and sometimes in the main window.  I want it to be
display differently (with a header) when its  not
in a frame.  Is there a way I can do this?

I don't suppose the name of the target frame
gets passed to the browser does it?

Presumably the only way to do this would be
to do it in client-side code and fecth the header
if appropriate and filter it to make it what is
needed.  Or is it?

Calling a method with () is a python convention.  HTTP has no convention
of calling anything, we just use the convention that the query string
(everthing after the ? in a URL) is a list of name=value pairs seperated
by &.  This is per the CGI specification.

I'm getting a weird invalid character error on my ZSQL Method using
ZOracle... If anyone could help, I would appreciate it:

I have a method with the following params:

    id username password firstname lastname title deskphone cellphone
pagerphone emailaddr soffice_id sprdarea_id

And the following query text:

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values
      (<dtml-var id>,
       '<dtml-var username>',
       '<dtml-var password>',
       '<dtml-var firstname>',
       '<dtml-var lastname>',
       '<dtml-var title>',
       '<dtml-var deskphone>',

       '<dtml-var emailaddr>',
       <dtml-var soffice_id>,
       <dtml-var sprdarea_id>);

When I test it with example feild values, it renders the following
error:

    Error, oci.error: (911, 'ORA-00911: invalid character\012')

With this SQL Used (which if you try in SQL*Plus, is perfectly valid):

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values

They return query results, which are a sequence of record objects.

Yes.

If you tell it to, check out the 'Advanced' tab on ZSQL Methods. 
(First, don't forget to specify one argument to the method or else you
won't see what I'm talking about).

First it finds Flavor, then it traversed into Flavor, then Flavor find
the next element as its argument (once again, if you tell it to).  So
essentially the answer is yes.

Yes.

If rss wasn't there and it was in your URL then you would get a 404
NotFoundError.  If 'Cherry' is your last argument then yes, it would
acquire the first 'index_html' object that it found, which in this case
is the one in the root folder.

Greetings,


In my experience, to count the size of an array in ZOPE does not require an
external method, simply "_.len(sqlQuery())".  I use this myself in a few places.

I won't try to guess your reasons for not getting sql to count, but surely it
would be by far the simplest way?

Thank you Michel,

After trying your suggestion I came upon this problem:

A white screen with "No Items were specified!" at the address:

   ../BOStorage/manage_delObjects?id=20000428164227

(BOStorage is where the objects are stored and I verified the id#
20000428164227)

Thanks.

Can they do that? How? Something funny in the license agreement?

Subject: [Zope] Use only part of a list sequence? or External Method to Insert ZSQL?
Message-ID: <019301bf8a24$162d8180$5e577e86@jmu.edu>

To all Zopists,

<background>
I have a form that has several dynamically generated options from a MySQL
database.  I have each option using a hard-coded array like
name="mylist[0]", name="mylist[1]", etc..., and keep the value blank unless
selection is made.  Everything is working fine.  In the next page, I will
insert the Authenticated_user as the userid, and another field into a table
in the MySQL database.  When I get to the next page, I have:
...
<dtml-in mylist>
    <dtml-if "_['sequence-item'] != ''">
      <dtml-if "countuser(`AUTHENTICATED_USER`) < 6">  ##countuser counts
user in table
                 will be inserted into tabel here...
      </dtml-if>
    </dtml-if>
</dtml-in>
...
People are only allowed to have 5 entries in the table.
</background>

Here are my questions:
1.  Should I use an External Method that accesses a ZSQL Method to insert
the fields into the table?
(please give me an example of this, it sounds interesting...)

2.  Is there a way to only use the first 5 listings of the sequence?  Maybe
save into another list, then go directly to a ZSQL method insert?

3.  Should I just quit and go home?
:o)

Any help would be greatly appreciated.

   No, it takes a string. Try:

<dtml-call "RESPONSE.redirect('/target?myvariable=xyz')">

redirect takes string.  The correct syntax would be:

<dtml-call "RESPONSE.redirect('/target?myvariable=%s' % xyz)">

Remember, once inside quotes ("") you're writing Python code.

Thanks again Mike.

So my final (I think, for now) question is this :

The whole point of Zope is to get a result back so the URL :

mysite.com/Users/Fred/Flavor/Cherry/rss

is (the way we have discussed it) really a way of saying : "I want an "rss"
document containing information related to User=Fred, Flavor=Cherry.

So in order to get my content out I just have to do some things with
<dtml-with Users> and <dtml-with Flavor> in my "rss" document? (because
these SQLMethods will already have been set up & run as part of the URL
traversal and are ready to give me data?)

I appreciate your patience,

- Ian Sparks.

That would be the last semi-colon ";". Remove it and use in the ZSQL method.
Additionally, instead of <dtml-var  ...>, you might want to consider using
<dtml-sqlvar >, which will assist you in properly SQLising the data.

Message-ID: <00031011262501.26896@localhost.localdomain>

Greetings,


So, I got into work this morning, ready for another day of zoping, only to find
my server not quite responding properly.  When i went to the manage screen, the
tree frame didn't fill, but the right-hand frame was fine.

Hmm, thought I.  Oh well... i can work without it.  So, I clicked on the folder
for todays work and..... 

nothing....


no response at all, not ever a timeout!

Talk to the network admin, we both kick about... and it seems that the ZOPE
server will respond correctly to invalid GET requests, but just freeze on valid
requests.

Further testing shows that it's ONLY when i try to use the management screens. 
The only change in my system recently has been upgrading from NS4.7 to NS4.72.

It's RedHat 6.1, and Zope 2.1.4.

Any idea?

Yeah, that would be very helpful.

As a Zope Newbie, who's developed lots of database stuff in PHP and Perl, I 
am unclear on whether I'm "supposed to" try to make everything an object in 
ZODB.

Say I'm making a repository of documents, like articles or e-mail messages, 
and I expect to end up with 100s of thousands of those, should I 
confidently work on making them all Zope objects, or should I stick with 
mySQL records and/or files in the file system, like I normally would?

As a follow up... i checked another site of mine, and it is now showing

The whole server seems to have locked up.

You don't even have to work that hard, consider what happens:

Let's say that your Users method queries a table that contains two
columns, name and title.  Primary key is 'name'.

Your second method queries a table that contains two columns, flavor and
size.  Primary key is 'flavor'.

Users method is called with 'Fred' as argument, this returns a single
record object.

ZPublisher then tries to find 'Flavor' on that record object, it doesn't
have such an attribute, but it CAN acquire it, so it does.  It discovers
that it is a SQL method and calls that method, *in the context of the
first record object* (keep that in mind...).

The second method is called with 'Cherry' as a argument.  It returns a
single record object.  Now, ZPublisher tries to find 'rss' in that
record object and fails, but it DOES acquire it, *in the context of the
second record object which was found in the context of the first*.

Now you are in the rss method, but you are also in the context of the
second and first result objects, in that order.  So in your method, just
say:

Hi my name is <dtml-var name>.     I'm acquired from the first result
object.
My title is <dtml-var title>.      I'm acquired from the first result
object.
The flavor was <dtml-var flavor>.  I'm acquired from the second result
object.
The size was <dtml-var size>.      I'm acquired from the second result
object.

Note that if a subsequent record object has a column name identical to
that of a preceding record object, the subsequent one is acquired
first.  This means that subsequent results can 'refine' previous ones.

Note that this concept of accessing one object in the context of another
is what is called Acquisition and all Zope objects support it, not just
ZSQL Methods.

--------------------------------------------------

(1) It should work. I have tested it. Nothing
    special is required for the __init__.py file.

(2) Make sure that you have an __init__.py file
    inside your lib/python/Shared/Local folder.
    This file can be empty. Or you can provide
    some __doc__ and __version__ string like
    Digicool people do. But it really can be
    an empty file.

(3) Inside that folder, create a file Chicken.py,
    which contains the following three lines:

    class Chicken:
        def __init__(self, size):
           self.size = size

(4) This python file will not compile automatically.
    It will only be compiled when it is imported
    by some other Zope modules.

(5) To test what you want: create an external method.
    In the folder Extensions inside your Zope root
    (if you don't have an Extensions folder, you
    have to create one first), create a file Test.py
    containing the following lines:

    import Shared.Local.Chicken

    def getSize(self):
        return self.size

    def test(self):
        Shared.Local.Chicken.Chicken.getSize = getSize
        a = Shared.Local.Chicken.Chicken(123)
        return a.getSize()

(6) Go to Zope management screen. Restart Zope.
    (Or shut it down and restart it manually.)

(7) Create an external method with 'Id' = test,
    'Function name' = test, Python module file = Test
    and click on the 'Edit' button, then click on the
    'OK' button. If you don't know what an external
    method is, you've got bigger problems than I
    thought. :)

(8) Hit the 'Try It' tab.

Done! now you can use the external method inside
your other DTML documents/methods. For instance,
you can have a mytest_dtml method with the following
lines:

<dtml-var standard_html_header>
<dtml-var "test()">
<dtml-var standard_html_footer>

and it will print the number 123 when you view it.

I shouldn't have treated you like a 3-year old.
But I guess making instructions as clearly as
possible eliminates unnecessary confusions. :)
We've all been newbies once.

This really isn't enough information for us to do anything except
console you.  Can you do some more investigation?  Try shutting down
your Zope and going to the lib/python directory and then doing this:

bash$ python
Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [GCC 2.7.2.3] on linux2
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import ZPublisher, Zope
>>> ZPublisher.Zope('')

Does that return your top level ('yoursite.org/') content?

Are you using some non-standard modules like SiteAccess?

Yes, I am using SiteAccess.  However, this site has been working fine for some
weeks now.  The site works until you go to the management screens.

Also, an older site of mine (running on Zope 2.1.2) has also shown the same
problem, which started last night.

Two seperate sites showing the same problems at the same time?  Coincidence? 
Not likely.

No you are doing it the right way and it should work fine.

Is there an error and a traceback?

Ha! This must be the most innocent message in a long time. :)

BookS on Zope? Good titleS? Get THEM? Oh boy, oh boy.

There is ZERO book on Zope. But DC people neither confirms
nor denies book deals, this is what I last heard.

All what I need to know in Zope I learned it from the
net, just like everyone else. :) The myriads of loose docs
plus the mailing list does the job. Poorly, but it does
the job.

A good Python book is a must, though, when you want
to get into more advanced features of Zope. O'Reilly's
"Learning Python" by Mark Lutz and David Ascher is
a good bet, well... maybe the only bet. :)

No error or traceback.  It takes me to the "manage_test" page and I can put
the number in manually, and it works.  The crazy thing is, I can force-feed
it the manage_test, like:

<a href="/queries/SearchResultPage/manage_test?theid=<dtml-var
the_id>">link</a>

and the test comes up ok. I don't have a clue on this one...

There are no books on Zope yet.  Mike released a plan some time ago about a
book that he was working on w/ O'Reily.  Maybe he'll give us some new info
:)

I suggest "Learning Python" to get more acquainted with python and then
using the mailing lists and stuff on Zope.org for now.

Later, Nick

The problem was on my end.  I was referencing the method instead of the

here at work to long.....

I think it's time to go home....it can wait 'till 'morrow....

Thanks for helping my step-back and think alittle.

I don't know what it is, but something had to happen, unless there is
some mysterious kill-your-Zope-on-Mar-8 virus going around.  The one
upgrade to Netscape is unlikely.  But *something* had to happen to both
boxes.  They may be related, they may very well be coincidences, but
neither of them manifested themselves by themselves, that is even more
unlikely.

Greetings Thomas and welcome to the Zope list.

One place you may want to start is WorldPilot (http://www.worldpilot.org).
WorldPilot is a will handle some of your needs. Its a web based PIM with
e-mail, scheduling, address book, and to-do list functions.

What type of document administration are you looking to do? I have some
Notes/Domino experience and if that is your reference point I may be able to
help you find answers based on Notes style solutions.

No nothing. Really weird. I have actually tried on a Zope instance that
was accessed only by one person and still it will silently stop after some
time. Nothing related to heavy load ...


Could be related to GUF as I was getting some exceptions from GUF but they
were uncorrelated in time.

Thanks a lot Nick

I haven't tried out your suggestions yet but I *hope* they point to the
problem. You write nevertheless that in your case Zope hangs, whereas in
my case the process just dies silently and doesn't even trigger the
manager to restart it. I will try my own supervisor on it and see how it
behaves.

I don't think you need to really get out of your way to crash python. For
someone discovering __getattr__ for the first time and wanting to do some
simple delegation ...

class A:
    def __init__(self):
        self.a=[]
    def __getattr__(self,key):
        if hasattr(self.a,key):
            return getattr(self.a,key)
        else:
            return getattr(self,key)

Wrong but not really bizzare IMO

The story so far...


Well, the second site which appeared to be showing the same problems... isn't. 
It is now working fine.  So, I'm left with just the first site, which is
currently the more important site.

I can traverse normally, until i try to enter a management view.  Then, the
frames arrive, and, upon first attempt, /manage will work, except for the left
frame.  After that, no manage screens work at all.

I do have SiteAccess, but even with __no_before_traverse__, the same problem
occurs.  I can go back to regular pages, and all is fine.

Please come to see the http://zope.org/Members/kentsin

This is a set of method/attributes which will publish the folder's index_htm

The methods will generate the doctype, stylesheet, javascript, rdf for the

It can be configure by setting certain attributes.

Your problem definitely seems to be coming from
SiteAccess. Evan should be able to help you out.

What you may want to do first is to disable
SiteAccess first. Something like:

http://www.whatever.com/__no_before_traverse__/path/to/rule/manage_main'

Then go to the management screen and UNDO that very last thing
that causes SiteAccess to get into infinite loop. If Zope is
not problem, do you have Apache re-write rules somewhere
modifying your URLs?

The first time I used SiteAccess was also my last time.
It was so freaking scary to have a hang-up situation where
you cannot do anything except cry in desperation. :)
Several people have reported problems with SiteAccess.
It's not that I don't think SiteAccess is great: its
concept is great, just that I don't ever want to get
into this kind of scary situation again. :) I am waiting
another few months before I get more reliable version
of SiteAccess or its equivalent in Zope. And no, thanks,
I won't be a guinea pig to reproduce the bug. :)

Subject: [Zope] Zope + Coda = Client Side Zope?
Message-ID: <00030922411300.00635@viking>

Some of the dsicussions in the Client Side Zope thread got me to thinking about
an article I read in Linux Journal sometime ago on the Coda file system. As
luck would have I can't seem to find that issue. Most of the information
contained in that article (now over a year old) can be found in updated form at
http://www.coda.cs.cmu.edu/ . 

For those who've not heard of coda its a distributed filesystem that supports a
variety of the features, including disconnected operation and replication among
multiple servers, that were mentioned in the previous thread. 

I will admit to knowing only the very surface information about coda and throw
this to the list for anyone who has actually used it. Also do any of the DC
folks think that a data store centered around a coda type fs would be doable?
I've been intrigued by coda since I first read the article this may be the
reason to explore further.

Any other thoughts on this?

(I read your post and understand you have this working now)

Just wanted to mention there is another 'shorthand' way:

<a href="/queries/SearchResultPage?theid=&dtml-the_id;">link</a>

A little more compact than the one with <>s.

Server is still up, but I'm wondering if these channels reopen or if
they all close if that's what stops the server?

I can see how this exception is getting left unhandled in the medusa
code, so I'm going to try and catch it and startup the server again.

Greetings...


After trying constructing an entirely NEW zope install, and winding up with not
being able to import the backup of my site, I decided to reboot.

Strangely, everything is working again.

Oh well... at least i've learned some more about the innards of Zope.

Thanks for all those who joined me in my futile search for an answer.

Absolutly, but in this case you can just use FileStorage, since coda is
a filesystem.

I attended the Coda session at last year's Linux Expo.  There, the
professor in charge of the project gave a very clear explanation of coda
and how it works.

Useful results with Zope should be immediate, Simply store your Data.fs
file on a filesystem that is replicated by Coda.

There is a more interesting application however, and that is
implementing the actual coda protocols themsleves into a sort of
ReplicatedStorage (I'm not positive if that is the best way to slice the
pie, but it's an idea).  Another idea is to roll a similar or identical
protocol into ZEO, so that not only are Storage Clients and Storage
Server are distributed in a parent/child relationship, but also that
Storage Servers can be distributed in a peer relationship that replicate
each other to provide failover and replication.

Interesting stuff in any case.  I'd really like to hear about someone
who has a success story with Code and Zope using just it's filesystem
capabilities.

Subject: [Zope] WorldPilot Acquisition?
Message-ID: <CC59868A0A76D311B1F50090277B321C1F31BA@VRTMAIL>

I've been mucking around trying to get Acquisition to work with WorldPilot
objects (I want to define methods/documents that can query WorldPilot's
"normal" objects (Events, Address Cards, Notes, Todos, etceteras), and the
collections of the same.  So far no luck (I don't really understand
everything going on under the covers of either Zope _or_ WorldPilot, so I'm
not likely applying pressure at the right points).  I've been adding
Acquisition.Implicit to the hierarchies of just about every object with no
luck so far.

Does anyone have ideas on how to go forward?  Could I alter the "normal"
objects in some way to make them accessible at a higher-level (for example,
if I could get at the objects in a flat collection, I could run my queries
against them, using their types to sort into virtual collections).

I suppose, in a pinch, I could just read the local files and construct a
query against them, but that seems... well, too incredibly hacky.
Incidentally, why does WP use all these custom storage mechanisms?  The
actual objects don't seem too complex, and the interface doesn't _seem_ like
it would require the support.

Ideas appreciated,
Mike

If we can gather enough support for something like this, I'm all for it.

Um, no. Since the code that defines 'layout.table' is also available and
editable, (just like any other object).
So you can not only code the specific header you want into the object, but also
create a parameter which can be used like so:

 <dtml-var object="layout.table">
   <param name="datasource" value="get_above_age">
   <param name="columns" value="Name,Age">
   <param name="table_tagattrs" value=" border=0 bgcolor=green">
 </dtml-var>

I learnt you're doing something similar (from Rik). I have to look at it.

What I'm suggesting is that instead of having to create a product every time
you want a higher level object, we could have a framework so that you could
just create an object that does it. The goal would be to make it easy for
everyone to code their own component objects (or templates, or patterns,
or whatever)

Another thing I would like is that people start looking at 'documents'
differently. Instead of 'my_element_header' and 'my_element_footer', people
think of 'my_element' which takes one or more parameters. (Please don't flame
me, it's Paul who started all this :-)

I guess not. The problem I  have fits the description, but I don't use GUF.
I have the impression though it has to do with busy interactions with a
Gadfly database. Platform: Windows NT, Zope 2.0.1.

Message-ID: <38C8CAC9.C45A5056@nipltd.com>

Just an idea, but if you want to see if it's a bug, or 'non-standard' html
problem in Zope, try copying the 'view source' html of the tree into an html
document and editing it in Dreamweaver.

Dreamweaver seems very good at finding html problems, and you can run tests to
see if any browsers aren't going to like it.

Hope this helps...

Subject: [Zope] trees, hypernews and frames
Message-ID: <38C8C8E0.AB71B295@open.ac.uk>

Sorry, this is involved and takes a lot of words to explain.

I'm building a zope site which also serves HyperNews
discussions.  Apache and Zserver are working well together.

What I have is a tree widget iterating over a folder,
some of whose elements are treated as hyperlinks to hypernews
discussions.  Base articles for discussions are in the
contents of the zope items so .... when  you click
on an element in the tree it follows a link to hypernews
and the hypernews fetches the contents of the "same
item" you just clicked on.  This is a roundabout
way but the only way I know to keep my hypernews headers
and stuff in zope It does all work well but....

My first implementation had a two column table with
the tree on the left and the particular discussion on the
right.  This worked well logically but wasn't too visually
appealing because as you expanded/collapsed tree branches
everything moved around on the page.  So I re-organised
it to use frames - a header frame, then two columns
(tree in one, discussion in the other) and a footer
and this works very well.

My problem is now this - except for the top one
the frames on the page do not include 
what in the former implementation was the header (i.e.
the fancy bit at the top that gives context and doesn't move).
Now its possible and common to access the hypernews discussions
without coming in through the zope home page with the tree
widget.  It is common to do so because when hypernews sends
email it puts a hyperlink to the item in the email which
does just that.  When this hyperlink is followed the page is
fetched from zope but of course the fancy header isn't there.
Since its no longer displayed inside the frameset the
header needs to be displayed as well but isn't.

That's the crunch.  How to get the fancy header served
when its displayed outside the frameset but not served
when its inside.  If it were all in zope then this could
be done by passing a variable value so the page could
know how it was called but hypernews does not pass on
anything like this when it fetches content from other
servers.

Anyone think of a way round this?

Please copy replies to
a.k.heath@open.ac.uk
as I take the digest.

The Guides on http://www.zope.org are available for download and can be printed

Seriously, though, they are a bit out of date but certainly a very useful for a
beginner. the order I'd recommend:

Zope Content Managers Guide
Zope DTML Guide (more of a reference really...)
ZSQL Guide (if you want stuff out of a DB)
ZClass Guide (this is probably the worst of the guides and I personally didn't
find it very helpful...)

All available from http://www.zope.org/Documentation/Guides

You can easily turn off ZServer's http server but still leave the other
servers.  Or you can turn them all off except for PCGI.  See the usage
documentation in the z2.py file in the Zope top level folder.

Hi all!

I'm quite new at this whole Zope thing, so I'm probably overlooking 
something quite trivial.
Here's the deal:
I've uploaded some text files into a folder called "Taglines" there are some 
30 files in all. Now for the problem: How do I search the contents of the 
files?
I made a ZCatalog and I know I have to make an index on "something" but I 
can't find what that something is.
Can this be done? And if so: How?

greetings,
Bart Holthuijsen.

Subject: [Zope] REQUEST vraible methods
Message-ID: <38C8E437.3B1D9AC9@nipltd.com>

Hi,

I'm trying to write a SiteAccess Rule to do some simple virtual hosting helping.
Basically, I'd like to have access from http://www.mydomain.com (which is
virtually hosted...) and from http://zope-host.nipltd.com/mydomain (the actual
Zope host) and have all the management views, absolute_url()'s, etc working
properly.

If you just drop a SiteRoot in /mydomain then everything works fine through
http://www.mydomain.com but http://zope-host.nipltd.com/mydomain/manage just
jumps to http://zope-host.nipltd.com/manage. So I'd like to write my own Access
Rule to do this.

Now, the documentation for SiteAccess mentions a few methods of the REQUEST
object that I can't find documentation for. I was wondering where I could find
complete documentation for the REQUEST object, or how I can find out what its
data and method attributes are?

cheers,

Chris

   You don't need AccessRule for this - just path correct SiteRootBASE and
SiteRootPATH environment variables to SiteRoot. Define it differently on
every server, that's all.

Hmmm,

Not sure I get you, and I'm not sure my explanation was clear... ;-)

I'm only dealing with one server, which hosts several sites.
Each site is in its own directory off Zope's root.
eg: http://zope-host.nipltd.com/mydomain

Each of these sites has its own domain name, which is virtually hosted using
Apache as a front end into Zope. 
eg: www.mydomain.com --> http://zope-host.nipltd.com/mydomain

Now, we typically maintain the sites with:
http://zope-host.nipltd.com/manage
and navigate through the links from there.

However, site owners may maintain the site with, for example:
http://www.mydomain.com/manage.

Also, currently, wherever there's an absolute_url() or the like, such as in the
management screens or in Squishdot sites, links are generated as follows when
accessing through www.mydomain.com:
eg: http://www.mydomain.com/mydomain/manage

If you follow these links, they work through the magic of aquisition but,
through following several such links, you can end up with rediculous URLS.
eg: http://www.mydomain.com/mydomain/mydomain/mydomain/mydomain/manage

I think SiteAccess's Site Root's are designed to sort this out. You drop a Site
Root with a path of / into the /mydomain folder.
Unfortunately, this site root also affects access through
http://zope-host.nipltd.com/manage and so if you try and follow the link to
http://zope-host.nipltd.com/mydomain/manage_workspace you in effect get
redirected to http://zope-host.nipltd.com/manage_workspace 'cos the Site Root
strips out the /mydomain.

Also, if you go to http://zope-host.nipltd.com/mydomain/, all the links are
broken for the same reason.

Which is why I want to use an Access Rule instead and make it a little cleverer.

Which is why I'm trying to find out what methods/variables there are in the
REQUEST object, which doesn't appear to be documented very well ;-)

cheers,

Chris

Actually that's not _completely_ true.  The Quick Python book has a
chapter written by Brian Lloyd and Amos Latteier on what used to be
Bobo.  It's still a useful intro into the idea of object publishing with
Zope.

   Do not pass any SiteRoot* variables in this domain and pass both in
www.mydomain.com.

   SiteRootBASE => http://www.mydomain.com
   SiteRootPATH => /

That should do all tricks you want.

One tiny datapoint.

I set up a small Engineering Change Request system w/ zope and
PostgreSQL 6 months ago.  It has been running flawlessly [1] ever since.
Machine uptimes are in the mid-2 digits (i.e. about every 2 months we
have to rearrange things in the lab).  Note this is a very low load
application.

As for perl/python stability, you could go back and see how often
new releases come out and use that as an argument.

Okay, I think I'm starting to understand more, btu I'm still not quite there yet
;-)

When you say 'pass any siteroot variables' what do you mean?

Do you mean pass them from Apache?
Do you mean set them as properties somewhere?
or something else....

Well there goes this weekend. ;-) I've grabbed the Postscript copies of some of
the coda documentation and I think I'll attempt to set something up this
weekend if I have a chance. My "lab" setup includes a Linux server, a Linux
workstation, and a Windows 95 workstation, so I'll be able to check so measure
of "cross-platform-ness".

The idea of a ReplicatedStorage mechanism is what I was (mis)firing at with the
original question on feasability.  As I have stated before on this list some of
my background is Lotus Domino/Notes and this could bring Zope close to some
functionality of a Notes Client/Domino Server interaction. (I won't bore the
list with details if anybody wants some I'll be glad to do it outside the
bandwidth of the list, unless a lot people want it :-)

It looks fine, so far and i downloaded it.
I'm not sure if i understand the Workgroup-sharing correctly - can
different users participate at the same Address-book or Calendar?
I mean does it support a shared calendar for several people?

If yes, this Product is my way to go and Zope and WorldPilot will get another

I'm not entirely sure here - the client wants something that would be

to use LINUX and Zope. As i can tell, Notes/Domino may be exactly what

Do you know something that could would fit this?

   Exactly this. How do you access Zope from Apache? Proxy, FastCGI or
PCGI? They all have different methods to pass vars (and I afraid proxy
doesn't have such way).

   Properties will be used for all domains, that why I said set path
property empty in SiteRoot.

You can set any terms you like in your use license. Whether they are
enforcable in a civil court is a separate question. For example, all
through the '80s Oracle Corp. had a restriction from including Oracle
product in any product comparison, such as benchmarking. 

Sometime in the early '90s Oracle Corp. lifted that restriction. It may
have something to do with the fact that Oracle was finally running fast
enough to look good next to Informix, et. al. 

Microsoft picked up on this mode and had similar restrictions inserted into
SQL Server licenses. I didn't know about that part of Microsoft's license
until I heard Larry Ellison talking on a radio interview, blasting Uncle
Bill for this dispicable practise!

Okay, we use proxy :( . Also, the URLs are rewritten by Apache so that all the
relative links don't go to http://zope-host.nipltd.com/mydomain/*whatever* as
opposed to http://www.mydomain.com/*whatever*

What I was thinking is to write a Site Access rule as follows:

If the host name is zope-host.nipltd.com:
	do nothing
else
	<dtml-call "REQUEST.setURL(path='/')">

Maybe storing zope-host.nipltd.com in a property of the root level folder too.
My only problem is finding out what the host name is.

Will REQUEST.environ.HTTP_HOST be set by the time an Access Rule is called?

Subject: [Zope] how to tell if displayed in a frame
References: <38C82A33.B333748A@open.ac.uk>
Message-ID: <38C9047B.53DAD777@vt.edu>

It can be done in server-side code, if you know when you put the
document in a frame or not.
Something like the following might help:

In the document in question, do some code like:

<dtml-if in_frame>
...display definitely in frame
<dtml-elif not_in_frame>
...display definitely not in frame
<dtml-else>
...default display, which may be the same as one of the above
</dtml-if>
You will probably want to factor out the duplicated content into
subsidiary methods.

Now, if you want the default view, call it as <dtml-var mydoc>

If you want it in its frame view, call it as <dtml-var "mydoc(_.None, _,
in_frame=1)">
You might want to make a dtml method called e.g. myframedoc with the
above code so you can call it as a url.
<frame src="myframedoc" title="blah">

Another way is to call the document in HTTP:get format in the frameset.  
like: <frame src="mydoc?in_frame=1">

Thanks for solving the immediate problem Phil - another UK Zopista - 
there's a few of you out there ! I think I've had help from all of you in 
turn :-)

However I think this reveals a basic problem with the syntax which is 
causing me grief and presumably there are others like me out there.

I would expect an object to behave consistently wherever it was used - so 
if it renders/returns/evaluates to 'zope' inside a dtml-var I would expect 
it equally to render/return/evaluate to 'zope' inside a dtml-if.

If it doesn't then surely we have an inconsistent syntax. How do we know 
how any object is going to behave inside a dtml tag ?

Any comments ?

Why do you want to do this? Have you thought of why it is there?

Create a folder 'Foo' with an index_html method in that Folder, and a 'bar'
method. The index_html document contains a relative link to bar
(href="bar"). Next, go to the URL:

  http://your.server.name/Foo

Note the lack of a trailing space. If you now follow the relative 'bar'
link, you'll neatly end up in http://your.server.name/Foo/bar.

However, had you removed the BASE tag, your browser would have attempted to
load http://your.server.name/bar instead. This is because the relative URL
is offset against the last slash in the URL. The BASE tag however, tells
your browser that the actual URL of the document it is showing, contains an
additional slash.

So, unless you have a really good reason, you don't want to remove that
slash. And if you do, you have to make absolutely sure that the visitor will
never end up on a URL of which the browser needs to be notified is different
from the actual URL.

Richard,

As someone earlier today on the list said, "if it's in quotes it's python"
(or something similar).

Basically Python rules apply when using any expressions in zope dtml-var and
other tags.

Well, that's how I think of it.

Subject: [Zope] News ZClass Question
Message-ID: <013601bf8aa5$e2733060$0a00000a@smartway>

Hi all !

I try to learn Zope...

I have a very simple ZClass myClass.
This Class has few properties (let's say title:string, description:text).

I would like this class to have 2 methods that can render its instances
simply.

Let's say DTML Methods :
render1
render2

I've made thoose two methods in my Class :
ex :
render1 :
Title : <dtml-var title><BR>
Description : <dtml-var description fmt="structured-text" newline_to_br>

and render2 :

<B>Title</B> : <dtml-var title><BR>
<B>Description</B> : <dtml-var description fmt="structured-text"
newline_to_br>

(the examples are stupid !)

But when I call the methods from the index_html of my content folder like :

<dtml-var "myClass1.render1">
or
<dtml-var "myClass1.render1()">
or
<dtml-call "myClass1.render1(myClass1)">
or
<dtml-call "myClass1.render1(_.None)">

None of theese shows me the infos :(((((
Sometimes, i have AttributeError, sometimes Authorisation PB :(


Please help !

I still think it's an inconsistent syntax.  It should be possible (by
overriding __coerce__, I think?  I haven't had time to look this up yet)
to make the == operator do something different.  AUTHENTICATED_USER is
often used as a string (at least what I've seen of it ...)

Also, "if it's in quotes it's in python", why do I need to do _.str()?  
why does dir() not work?  It seems like some pretty horribly munged sort
of python...

In-Reply-To: <Pine.LNX.4.10.10003101041100.26820-100000@jeff.goingv.com>
Message-ID: <NDBBLENPLCPAHKODFHNGAEMHCNAA.morton@dennisinter.com>

A number of people have expressed a desire to have XSL support in Zope. The
projects I am working on also seem to be needing the application of XSL, and
whilst we can (and will) use some external XSL processor, it would seem that
a 'cleaner' solution would be to have XSL support directly in Zope.

I originally came to want to use Zope because I needed a tool that allowed
the manipulation of a persistant tree of objects; my prototype was done in
XML, but it needed persistance, an interface, and a programming language,
hence the use of Zope. Even having only XPath support would be an extremely
usefull way for packaging up simple 'queries' on the Zope database.

Ive been looking around at the Python XSL implementations and the
FourThought 4suite is looking pretty damned good, especially considering
their goal of eventual ODMG 2.0 support. Zope desparately needs some
standards compliance, even if only for the buzzwords.

The question on my mind is: how much do other people want XSL in Zope?

Im willing and able to put some $$$ up for a bounty on this. Is anyone else?

I guess Id also like to heard what DC has to say about this; whether they
are willing to have an external group contribute/merge a key technology into
their codebase, and if they have any preferences about who this group might
be.



---------------------------------------------------------------

Heres what Uche Ogbuji of FourThought has to say about Zope
http://www.pythonjournal.com/volume1/issue2/col-intranetpython/

The Zope Dope
Digital Creations, fresh from a capital infusion, has given Pythoneers their
first complete native Web application platform in Zope.  the "Z Object
Publishing Environment".  Zope is similar in scope to Cold Fusion or
SilverStream, but open-source and python-powered.

Zope accumulates many bits and pieces of a successful Intranet site.  It
incorporates a database management system with object extensions (which,
unfortunately, doesn't yet support the Object Database Management Group's
specifications) as well as facilities for developing template Web sites, an
application framework, a CGI mechanism for handling HTTP requests for
objects, an HTTP and FTP server, and a comprehensive application framework
to tie it all together.  Z Templates are developed using a proprietary
XML-based language, the Document Template Markup Language (DTML).  ZTML does
make some departures from the XML community in such areas as style-sheets,
but it is hoped that Digital Creations or other contributors to Zope will
work to close that gap.

Zope is a synthesis of Digital Creations' many earlier products, such as
Bobo, Principia and PCGI.  Bobo has been especially popular among Python/Web
programmers, and Zope looks poised to retain the tradition.  If Zope can
move a bit closer towards object database and XML-processing standards, it
is likely to be quite popular outside the Python community as well.

I would like to use an External Method to access a record field from a ZSQL
method by referencing another field in the record.  If I set the External
Method up such as:

def viewfield(self,reference_field,search_value,field_value):

where:
reference_field = So that I can tell it the field I want to reference
search_value = The value of the reference_field to query
field_value = The value of the returned field, that I was looking for

Do I use a "return" or a "result" or something else?  I still don't have a
handle on python yet, so I'm not sure what to put on the second line of the
method.

Subject: [Zope] MySQLDA / MySQLdb problems
Message-ID: <NDBBLBELNHAPHBBCOIFDGELDCBAA.ewalstad@energywright.com>

Hello all,

I have tried everything that I can think of (& a lot of what some of you
could think of) to get MySQLdb to compile and install.  I have had no luck.

So, I am now trying to install MySQLDA (a step back) and am still having no
luck.  I'm hoping that the MySQLDA problem is related to the MySQLdb problem
and that one of you will be able to point me in the right direction.

Here's what happens when I try to install MySQLDA:

First, the 'make -f Makefile.pre.in boot' script seems to work fine, but
I'll include the output anyway, just in case.

<OUTPUT OF make -f Makefile.pre.in boot>

As far as I know, I don't thing it's possible in Zope. I'm very interesed in a
way to do that, so I thought about a possible solution:
- make an empty class in python, e.g. MySuperClass;
- when creating your ZClass, make MySuperClass one of its Base Class;
- if you want to modify your ZClass Base classes, just add super classes to
MySuperClass and create/modify and __init__ method in it:

class MySuperClass(NewBaseClass01, NewBaseClasse02...):
	def __init__(self, parmeters...):
		NewClass01.__init__(parameters01)
		NewClass02.__init__(parameters01)
		...
It sounded a good idea to me and worked fine in python. However I got:
******************
Error Type: TypeError
Error Value: unbound method must be called with class instance 1st
argument
******************

Not very useful but who knows. Let me know if you figured out a solution.

Subject: [Zope] kind of variable in a document
Message-ID: <E12TUJB-0000FK-00@devel1.axiom.internal>

Hello,

I am trying to display a sequence of numbers with next to each of them the 
cumulated value of the previous ones. Thus, I was trying to declare a variable 
buffer to add at each cycle the value of the new number. But I can't figure 
out how to create a variable.

Can somebody tell me how to declare such variable?

Thanks,
Laurent

Hi,

I have an External to create object instances and add them in a Folder. As
expected they appear in the management screen. How to do that? If not, how to
display these instance (at least their ids) and how to delete them.

Hi, Laurent

Something like the following should work.

<dtml-call "REQUEST.set('mylist', [0,1,2,3,4,5,6])">
<dtml-call "REQUEST.set('cusum', 0)">
<table>
<dtml-in mylist>
  <dtml-let myvar=sequence-item>
  <dtml-call "REQUEST.set('cusum', cusum + myvar)">
  <tr><td><dtml-var myvar></td><td><dtml-var cusum></td></tr>
  </dtml-let>
</dtml-in>

I've always noticed the same thing, over a period of months. I'd also like
to know what it signifies. Is the list stored in the ZODB, and is this
therefore indicative of the kind of performance than can be expected with 6k
records? Or a relational table? It's not very impressive, makes the member
list something to avoid, and it's undoubtedly fixable...

Even if it gets "fixed" right away, it'd still be useful to know what the
problem was.

Subject: [Zope] Trees with DTML Methods?
Message-ID: <38C9562C.8B33C8E3@pacsg.css.mot.com>

http://www.zope.org/Members/anthony/tree-coding-tricks
"How-To: Some Neat Tricks with dtml-tree"
seems to imply that I can use trees on things other than ZODB objects.

But I've been banging my head against the wall on this for some time,
and I can't figure it out.

Here's what I've got:

An index_html document:
<dtml-var standard_html_header>
<dtml-call "REQUEST.set('eid', '1000')">
<dtml-tree id=eid branches_expr="GetEmployees(eid=eid)">
  <dtml-var eid>
</dtml-tree>
<dtml-var standard_html_footer>


A DTML Method called GetEmployees that returns test data:
<dtml-if "eid == '1000'">
  <dtml-return "[1001, 1010]">
</dtml-if>
<dtml-if "eid == '1001'">
  <dtml-return "[1002, 1003]">
</dtml-if>
<dtml-if "eid == '1010'">
  <dtml-return "[1011, 1012]">
</dtml-if>
<dtml-return "[]">


What I get is an infinitely expanding tree of two pairs of 1000's:

- 1000
    + 1000
    - 1000
        + 1000
        - 1000
            + 1000
            + 1000
+ 1000

What I don't understand is how the stuff from branches_expr is supposed
to change things around.  And, not coincidentally, that seems to be the
problem with this code....

Thanks for any help.

Uuupps, Thanks. I knew I'd forget to remove it.
I already got used to reading time in epoch UTC ;-)
worldpilot.1.0.4 fixes it.
I included WPsmtplib.py and WPimaplib.py and use them now instead of the
originals to avoid dependency problems in these modules

I took a look at the imap code. it basically complains that
the SELECTed folder is not read writable.
As far as I can remember the problem may be that UW IMAP locks your
folders when they get selected.
Possibly you're accessing that folder with a different client
concurrently?

Let me know if that's the problem, since I have heard about this problem
a few times, and I thought it was a locking issue on UW IMAP.

If not we'll have to look into it.

You are using a version of MySQL that is too new, I think.  I haven't seen this
one in a while, but I think I recognize the error messahes.  Try dropping back
to 3.22.25 (3.22.26 might work, but I know that .25 works and >.27 does not).
Send me a private email if you need a copy of the rpms.  I am sure I have thenm
somewhere

It is not inconsistent because all things behave consistently within
quotes and consistently without quotes.  You just have to know the rules
of each case.  Granted, it's not pretty, but it's consistent.

It's never used as a string because it is not a string.  You can't use
the word 'string' unless you are talking about python expressions.  DTML
does not have types, you must rely on python's expression machinery to
get down to thinking about the types of objects.

This is for security reasons.  We've overridden many of the built-in
functions like str and dir with our own so that DTML programmers cannot
do mean and nasty things, intentionally or unintentionally, from DTML.

It doesn't use the Catalog.  It's a plain Zope folder.  This means that
the folder object, including it's dictionary of childer, is loaded into
memory every time it is accessed.  This is the inefficient part. 
Folders were never meant to contain this many objects.  This is not
neccesarrily a lack, Linux directories are not that efficient either. 
Try putting 6000 files in one ext2 directory and then type 'ls'.  Pack a
lunch.

What is needed is a Folder object based on a more efficient storage
mechanism, like BTree.

I'm all for this.

And here comes the but.

But, 4Suite is not suitable (i.e. doesn't compile) for Win32 at the moment
(that's from the horses mouth, well Uche at least).

There was talk of win32 binaries but they seem to never have materialised.

I sopke to Uche today, and supposedly there are people who have had it
compile under win32. Im tracking them down at the moment. 4Suite may not be
suitable at the moment, but not because there arent win32 binaries.

I suppose line 1125 of mySQLmodule.c is something like:

If this is the case, try applying the following patch to your

Yes!  But I think that the concurrency might be happening from
Zope/WorldPilot?  I.e. that it is submitting another command prior to
the first results?  I ran (the patched) imaplib.py by itself (it has a
"sample session") which gave "reasonable" results...

Or, it might be an instance of the way recent UW imap daemons deal
with the maildir issue, copying files to the local user account from
the mail spool...  (see documentation, which I'm not yet sure that I
understand; but then again, I'm a research biostatistician, not a
sysadmin/www-master...).

I replicated it using UW imap locally on the linux (debian) box.

Maybe I'll try firing up Cyrus -- does anyone know if it "drops in" in
the same way that UW Imap does?  (i.e. install and go...).  Debian's
got it, so maybe I can do that...

Now I'm confused. You have to restart the Zope server after untarring the
package. Does WorldPilot show up on the Product Management page? If not maybe
it was unpacked into the wrong place. Did you set up the directories that are
listed in the INSTALL.txt. One change that can be made to the instructions is
the permission settings on the created directories. You can set them to 755 and
user to the user that runs Zope and group to its primary group. For example I
run zope with user jack.users so my directories look like this:

drwxr-xr-x   2 jack     users        1024 Feb 17 21:33 sessions
drwxr-xr-x   3 jack     users        1024 Feb  1 23:04 storage
drwxr-xr-x   2 jack     users        1024 Feb  1 23:04 user

The first time installed WorldPilot I think I had a permission error and ended
up with a broken product in the Product Management section.

Hope this helps.

Hi Patrick -

What happens if one manually deletes a file that is part of a transaction
involving many objects/files? How would transaction boundaries be enforced
on a filesystem? I am interested in hearing your thoughts on the issue
since it seems you have already done some work on it.

The following test was done with the WorldPilot Note facility and I suspect
would be similar in the calendar. I have three test users on the system
tester1, tester2, and tester3. I logged in as tester 1 and created 3 notes: 1
private, 1 public, and 1 confidential. I then added tester2 in the sharing page
with browse and read access. Tester3 only got browse access. Tester1 sees all
three notes, tester 2 the public and confidential, and tester3 the public. If
you have resources that need scheduling you should be able to set up userids
for the resource and let it have a calendar that is open to appropriate people
to read and/or edit. There may be a easier way to do this and maybe Ryan will
let us know if/when he sees this. :-)

I've not had a chance to work much with Exchange Server but if memory serves it
doesn't do much more than a standard IMAP server in the sense of
mailboxes and shared folders. It provides support for calendaring and address
books (with client support for LDAP, another of the things on my list of things
to learn.) So beyond that it depends on what they want to do. 

Good Luck!

Yep, although this would greatly improve my assertion that unix dirs,
like zope folders, are not efficient enough to handle 6000 objects, it
would not effect my assertion that zope folders need a more efficient
storage mechanism.

I know this is probably what you meant Patrick, I just wanted to be
explicit.

In this light, I have experimented with a BTree folder.  I posted the
code to zope-dev eariler this week.  Anyone get a change to see it? 
Anyone interested in actually improving it?

I have done nothing on this, unless you count daydreaming. ;>) At one
point, I had idly asked if anyone thought this might work, expecting
that some knowledgeable soul would immediately shoot the idea down.
Surprisingly, both Jim Fulton and Hans Reiser seemed to see that it was
in the realm of possibility, but not easy.

Of course, you have identified the hard part. Back in December, Jim
Fulton had the following reaction (below). Afterward, someone else at DC
told me that when Jim says it "getting transactional semantics right
might be a tad tricky" he means your head will explode. :)

Still ... since Linus Thorvalds has refused to add the complexity of
journalling to the Linux buffer cache, the people hacking on reiserfs
and other journalling filesystems, have been forced to implement their
own mechanisms for keeping track of dirty data. So one wonders if these
might be adaptable in some fashion, much as they are used to support
high availability network filesystems like Intermezzo, which exploits an
existing filesystem as a cache and wraps around it.

So, in answer to your question, I have no idea. ;)

===========

[Jim Fulton]
Would you imagine using the reiserfs as a ZODB storage?
If one was going to use a file system as an object store, 
then the reiserfs would be attractive due to it's effective
support for small files. Is this what you had in mind?

The ZODB has a well-defined "storage interface" that should
make implementation of a reiserfs- (or just an fs-) 
based storage reasonably straightforward, although getting
transactional sematics right might be a tad tricky.

Jim

One possible approach here is to have your proxy add a magic path element to
the path, sending http://www.mydomain.com/PATH to
http://zope-host.nipltd.com/PROXIED/mydomain/PATH.

Then have an Access Rule which says:

If "REQUEST.path and REQUEST.path[-1]=='PROXIED'" then "REQUEST.path.pop()"
and "REQUEST.setURL(path='/')".  There doesn't have to be a real object
called PROXIED, it's just a flag to be recognized and discarded by the
Access Rule.

I've just had a few frustrating hours trying to work out what was going on
with Zope.

It stopped allowing the addition of DTML-Methods. The connection would just
hang waiting for the Method to be created (also happened with DTML-Documents).

Turns out that /tmp was out of space temporarily. -- the disk that Zope
was running on had plenty of space.

It'd be nice if it would return low disk space errors rather than go off
into never-never land.

When in doubt, read the fine manual.  The _actual_ syntax you are using is::

  <dtml-var name="AUTHENTICATED_USER">

which can be abbreviated (and is, by almost every Zopista) as:

  <dtml-var AUTHENTICATED_USER>

The "name" form of the var tag is the "preferred" one, for the types of
applications DTML is really designed for: simple scripting of objects built
in Python.  It does several "automagic" things with the name:

  - If it is callable, calls it, passing the current object, the
    current namespace, and the REQUEST;  it then replaces the object
    with the result of the call.

  - If it has a string coercion (__str__) method, calls that and
    replaces the object with the result.

This behavior is the Right Thing (TM) for simple scripting;  but it _isn't_
Pythonic (the automagic stuff smells more Perlish, really).

The "in quotes" version is really::

  <dtml-var expr="AUTHENTICATED_USER">

but can also be spelt (and mostly is)::

  <dtml-var "AUTHENTICATED_USER">

The "expr" form of the var tag evaluates the Python expression (in this case,
to the object AUTHENTICATED_USER).  For fairly obvious security reasons, the
evaluation takes place inside a restricted namespace, without the usual
builtins;  the "safe" builtins are made available as members of the
"_" namespace.

The simplest disambiguation possible is to cease using the shortcut forms, and
always spell what you really want:

  <dtml-var name="AUTHENTICATED_USER">  <!-- DWIM: give me text!!! -->

or

  <dtml-var expr="AUTHENTICATED_USER.getUserName()"> <!-- DWIS,NWYTIM -->

Hope this helps!

I now just take my log files and run it thru a script to correct the

I got a quoted version of the object if I made

It does not evaluate the tags and quoted all < with &lt; and so they all
showed on the browser.

What rules determine when it will be quoted?

Also, I got the same result if I have

I can work around with

<dtml-with folder>
<dtml-var obj>

But how can I workaround "this"?

Actually, the Members roster is a bit more efficient. It uses caching to
store the results. This was added only recently, before the roster was
offline for a while because it was taking too much resources.

What happens is this:

If the cache has expired, or is empty, we do go through all 6000 Member
folders, and check wether or not they are listed. From listed Folders (just
over a 1000 now), we store the id and title in a list. This list is sorted
on id. Next we store the total number of Members found.

Then, we loop over the 6000 Member objects, and check wether or not they
have been active in the past two weeks. The number of active accounts is
also stored.

Together with a timestamp, this info is then stored as a volatile dictionary
attribute, and returned.

A next call to Members will return this cached information. Timeout of the
cache currently is 60 minutes. So, the batched pages and the searches use
this cached information.

There are a few reasons why it still may be slow:

1/ The cache has expired or is empty: we have to fill it again.

2/ The cache is per-thread. It isn't persistent, and therefor not shared
between threads. Your request could hit on thread first, your next request a
different thread, and then have to wait for the cache to fill twice.

3/ The volatile attributes don't hang around as long as I expect them to.
Maybe the object cache is a bit too aggressive, I haven't figured this out
yet. I haven't been able to get the cache to stay around for more than 20
minutes, but it is hard to verify and debug with 7 threads. I am not sure
about this one, because in the course of some extra testing I got to see
cache older than 20 minutes again.

4/ The dictionary containing the cache may be coming from swapped memory.
Currently, the Zope.org process grows quite large. This may have to do with
the up to 42000 Folder objects loaded into memory at any time. The Members
Folder holds references to 6000 Member Folders, and there can be up to 7 of
them (7 threads). This is an area where a BTree based folder would _really_
help.

5/ Plain network lag. Check other pages on Zope.org.

6/ CPU is hogged. The rendering of the ZQR is very expensive. If it runs,
the whole of Zope.org suffers. I am seriously considering disabeling it.
People really onlly need the pre-rendered version. I was testing just now,
had to wait way too long, and noticed someone was looking at both the normal
ZQR (rendering from XML), and the print preview version. The Members roster
came from cache.

I CCed David Kankiewicz on this, so he knows =)

1000 is still too many to be efficient in a regular folder.  You're
right that a BTree is probably the way to go here.  I didn't know about
the caching efforts, it seems like you went through some hoops to come
up with a better solution.

I think that we should seriously look into or have someone in the
community look into my BTree folder efforts to come up with a better
solution.  Depending on when I wake up tommorow, I'll see if I can fix
the various bugs in BTreeObjectManager and make an alpha release.

The only big question I can think of is, should BTreeObjectManager
replace ObjectManager?  Obviously not at first, but we should maybe look
into replacing OM with a more efficient form.  Looking strictly at
performance, I don't see any reason why this should be the case.  In all
cases, a BOM should be faster than an OM.  BOM are not any less
efficient in resource consumption either, and they are written in C, not
python.  Zope's BTree implementation is also very well tested, and
written by Jim, 'nuff said. ;)

Works for me. Especially if it results in a more up-to-date version in
pre-rendered style. Pre-rendered is about 6 months old, IIRC.

I imagine Zope is like anything else (basically) you would run in a

fine.

You may want to have alook at the Zope Product code for Zope Studio. I added
methods to the Application class, exactly what you want (watch it, long URL,
you may have to reconstruct):


http://cvs.zope.org/cgi-bin/cvsweb.cgi/ZopeMozilla/ZopeStudio/ZopeProduct/Zo
peStudio/ZopeStudioRDF.py?rev=1.2&content-type=text/x-cvsweb-markup

The important bits are 'import OFS.Application', and to assignments to class
members in OFS.Application.Application:

  OFS.Application.Application.zsTreeRoot = zsTreeRoot
  OFS.Application.Application.zsContainerRDF = zsContainerRDF

Note that the 1000 items is a sorted list of (id, title) tuples, _not_
Folder object references.

Once the cache is filled, we only have to display the precooked numbers,
take one _.len() of the listed members list for display, and have dtml-in do
it's magic on the afore-mentioned list.

The problem lies mostly in the fact that we have to access each and every
Member Folder to check if it is listed. Even if we use a BTree, we'd have to
load every Folder into memory. The same for the User objects in acl_user.

This is a side effect of using Extension Classes. From ExtensionClass.stx:

  Overriding methods inherited from Python base classes

    A problem occurs when trying to overide methods inherited from
    Python base classes.  Consider the following example::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            Spam.__init__(self,name)
            self.favorite_color=favorite_color

    This implementation will fail when an 'ECSpam' object is
    instantiated.  The problem is that 'ECSpam.__init__' calls
    'Spam.__init__', and 'Spam.__init__' can only be called with a
    Python instance (an object of type '"instance"') as the first
    argument.  The first argument passed to 'Spam.__init__' will be an
    'ECSpam' instance (an object of type 'ECSPam').

    To overcome this problem, extension classes provide a class method
    'inheritedAttribute' that can be used to obtain an inherited
    attribute that is suitable for calling with an extension class
    instance.  Using the 'inheritedAttribute' method, the above
    example can be rewritten as::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            ECSpam.inheritedAttribute('__init__')(self,name)
            self.favorite_color=favorite_color

    This isn't as pretty but does provide the desired result.

--
Another way, and I used this, is by bypassing the method binding, by
accessing the unbound method. The above example could also be:

        def __init__(self, name, favorite_color):
            ECSpam.__init__.im_func(self, name)
            self.favorite_color=favorite_color

The propertysheet variables become class variables, which are persisted as
well. So when you retrieve an instance, the persisted class that described
the behaviour of that instance is taken from the ZODB, and the new persisted
class has the .d attribute there.

In your python class however, .d is a instance variable, it gets set when a
new instance is created and __init__ is called. And exisiting instances
don't get __init__ called again, after all they were initialized already.
They only get their current state restored, and that state never included
the d attribute. Only on new instances, where __init__ is called, does d get
set.

You could get around this by making d a class variable, by adding d='I am d'
to you class definition. Alternatively, you could use the __setstate__
method, it is called when the instance is retrieved from the ZODB. It
revives the state of the object, and you'll have to remember to call
Persitant.__setstate__ as well:

    def __setstate__(self, state):
        Persistent.__setstate__(self, state)
        if not hasattr(self, 'd'):
            self.d = 'I am d'

'this' is an object reference, and it is being stringified. So the source is
returned, HTML quoted.

What do you want to achieve? Calling itself? ot very wise, as it would cause
an infinite loop..

If you want the source, do <dtml-var PricipiaSearchSource> and give the
Document a Proxy Role of Manager.

Well, here's a STUPID_LOG_FILE and a DEBUG.LOG during a crash.  I've
annotated the DEBUG LOG` as to when I think the crash occurred.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

I guess thats not the point here. Sure you can use POST for forms as
well
as GET. You can even "construct" A form-like URL for GET using
?var=value&var2=value
but you cannot send something inside forms without javascript over a
href-tag.

There is a really good Howto on the zope.org website that explains in detail how to
call a ZSqlMethod from an external method, and how to parse out the results
afterwards.  Follow those instructions and you shouldn't have any problems.  Your
email spells Extensions as 'Extentions', so make sure that this is not your problem
(probably just a typo, I know, but I thought I would check).

This might be a better idea. I'd use an external file, however.

This doesn't solve this. It's not the surfing of all those folders, it's the
accessing of the Members Folder itself. It's that folder that holds the

It is necessary when you want to call a DTML Method or Document from a
Python expression and you want that DTML Method or Document to be able
to look things up as an attribute of a 'client' or in your current
namespace (or any namespace you provide).  You can omit it when you are
using a DTML Method or Document _by name_ in DTML.  Note that:

<dtml-var IManager>

is the same as:

<dtml-var name="IManager">

and:

<dtml-var "IManager()">

is the same as:

<dtml-var expr="IManager()">

So most people use the first and third shorthand forms to use an object
by name and to execute a python expression respectivly.  When the DTML
Engine sees that you are using an object by name, it tries to do clever
things, like detect if it is a DTML object and to call the method and
pass the namespace 'magically'.

When the DTML engine sees that you are using an expression, it assumes
you know what you are doing and does no magic for you.  Therefore, you
must explicitly pass in the namespace.

> I'm also very unclear
> as to just what the 'client' is, especially since most of the examples
> I've seen involve passing in None for the client.

The 'client' is an object that you want to use as a namespace.  For
example, if DTML Method 'IManager' wants to find the name 'img' you can
pass a client object, and the method will try and do a getattr(client,
name) (in this case, name being 'img').  If you pass a namespace, then
it will try and do a namespace[name].  If neither of these succeed, it
will look for the name in the optional list of keyword arguments you can
provide.  If that fails, it raises a NameError.

The reason why it is None in most cases is because you want your method
to look things up using the Zope DTML Namespace (affectionately known as
'_').  In some special case however, you may want to explicitly provide
some other object.

This is single handedly the #1 obfusication in Zope and the most
frequently asked question.  We, of course, did not obfusicate this on
purpose.  When DTML was first concieved it worked by name only, so the
behind the scenes magic was acceptable and intuitive.  Later, we added
python expressions, and the ugliness of calling DTML Methods and
Documents became aparent.

Message-ID: <Pine.BSI.3.96.1000311155818.539I-100000@twirl.bitdance.com>

I've got a simple CatalogAware ZClass.  (CatalogAware is the only
class I added to its inheritance list.)  Everything seems fine,
but if I access an instance of the ZClass through the Catalog by doing, say,
getobject(data_record_id_), and then inspect the 'id' property of
the returned object, instead of getting the id of the object I get
the id of the folder in which the Catalog lives.  When I create
class instances, the 'id' in the meta-data is correct.  If tell
the catalog to update itself (or tell an item listed in the catalog
to update itself through the catalog management screen), then
suddenly the metadata id is also the id of the folder enclosing
the Catalog.

Is this a bug, or am I doing something stupid?  The object appears
under its id in all of the management screens, including the 'indexed
items' tab of the Catalog.

Hi DTML Gurus,

I am a newbie with DTML and i am trying to do the following with this script

1) using the subdirectory RegisteredUsers, check if a ZClass object of type
Player exists in the RegisteredUsers directory with an id that matches that
in the Request ( a form from the client ). This currently doesnt work for
some reason and i get the else case even if the object does exist.
2) In the else case i am then trying to create a new object of type Player
 a ZClass object defined in the GameSite product ).  I am creating the
object correctly in the correct place but the next bit of setting the
properties of  the player object does not work, and the object properties
are blank.

HELP !!

I have checked all the documentation for zclasses, dtml faq etc.  Can any
one help?

Is  there an easier/better way of achieving what i am trying to do, or am i
barking up the wrong tree ?


<dtml-with RegisteredUsers>

<dtml-if REQUEST['new_user_name']>

User currently exists

<dtml-else>

New user

  <dtml-with "manage_addProduct['GameSite']">

    <dtml-with "Player.createInObjectManager(REQUEST['new_user_name'],

I think I heard somewhere that it's now equal in speed to CPython, but 
I'm not sure. People use it to script Java components and such. It seems
to be reasonably popular for things like that in Java-land.

[snip explanation why open-source like collaboration is harder for languages]

It's hard for language *design*, yes, but it's less hard when you're doing
language implementation (for instance a faster one), and it's easier still
when you're writing libraries and such. And it does happen for language
design as well -- the Python static type design is currently being fleshed
out (in bursts) by the types-SIG (though of course Guido does final
approval about what goes into Python proper).

You'll find some of my silly messages too. :) The types SIG came quite
a long way after Guido proposed closing it down for inactivity. It's a bit
more quiet now, I believe.

There are various tools out there for Python which do offer this kind of

I think I see what you are trying to do here, but I don't think
DTML works that way.  The array reference is a python expression,
so you have to go to an expr.  But if you just enclose the above
in quotes you'll be testing whether or not REQUEST has a non-null
new_user_name variable.

One way to do what you want would be (tested):

<dtml-with RegisteredUsers>
  <dtml-if "new_user_name in objectIds(['Player'])">
  User currently exists
[...]

REQUEST is on the name space stack, so new_user_name will be found
without having to refer to REQUEST explicitly.  'objectIds' returns
a list of object ids, and the argument gives a list of meta_types
of the Ids to return.  So this call results in a list of just the
Player ids.  The python 'in' operator checks to see that the
left hand string is a member of the list of strings on the
right hand side.

Note: you'll run into some interesting issues with your planned
setup of the number of players gets large (say that large is several
hundred) due to practical limits on the capacity of Zope Folders.

Well, you may want to take a look at GUF and perhaps the (RealSoonNow) the
Portal Toolkit, but they may both be overkill for your application.
It depends on just what functionality you are trying to put into
your Player objects.

I forget which How-To I got this out of (maybe the CatalogAware
How-To?), but I think the call to update the property list function
name is (copied from some of my own code):

propertysheets.<your-sheet-name>.manage_changeProperties

Since your cut and paste dropped some stuff there, though, that may
be what you have, in which case I don't know why your properties
aren't getting updated.  Though you might try adding the _.None,_
arguments to the beginning of the call.

I'll repeat my question; why not use a relational database? Do you
need an object database? How is the ZODB too immature?

I'm having some trouble with it too, but perhaps that's just not being
familiar with the concept yet. But at least it looks less horrid than
some map()s and such.

Why so? I myself think Zope's source is an argument for explicit interfaces. :)

Well, tuples can be used as dictionary keys, lists cannot.

Forcing a *copy*, implicitly? But Python works with reference semantics
only? It's be nice to have a way to declare stuff immutable, I think,
but I'm not sure how often one would need to use it. There's something
to say for knowing something's a tuple, instead of having a list and
having to know whether it's immutable or not. Though perhaps that's
not a big problem in practice.

But that might result in a lot of incomprehensible code. I'm not sure if 
I'm in favor of having 'out' parameters anyway. constness as defined in
C++ is also tricky, as it infects code; everything that touches it
needs to be const-correct. Python tends to be less strict in this area.

[optimized statically typed modules calling classic python modules, why
is this tricky?]

Yes, it is doable but tricky in combination with static typing. See
the types-SIG for more info; I believe Guido has some messages on that.

Strange problem here - likely not related to Zope directly.  When our
content guys edit the DTML through the Zope management interface in IE 5.x,
the pages are properly displayed in IE 5.x (and assume 4.x).  However, in
Netscape, some pages do not display properly.  After running the DTML though
a code validator, the results indicate that the H/DTML is correctly
formatted for IE/Netscape 3.x and above.  We're aware of the normal
differences in table formatting, for example, between the different
browsers.

However, viewing the pages in Netscape 4.x, the source has all the "<" and
">" replaced with question marks.  This has been tested in Windows 98/NT 4.x
and Linux RH 6.1.

Now, I'm open to suggestions.  I am tempted to think this is a result of
some encoding issue, or perhaps  IE 5.x's handling of extended characters
but I'm at a loss.

This is likely some silly setting that we've overlooked but I thought I'd
check here first.

I've seen that behavior under Linux Netscape when viewing some sites.

Having worked with C++ for a long time, and later with Java,
I can tell you just how much I hated the whole thing about
data "encapsulation."

The whole mumbo-jumbo stuff about data hiding has one and one
single purpose: divide the programmers into engine programmers
and app programmers, so the engine programmers and exercise
full control over app programmers. It has more to do with
MONEY and corporate POWER CONTROL than with technology.
The private/protected keywords are an enterprise feature...
designed for big companies.

And generations of students are taught into this stupid
c**p about "data encapsulation." Funny thing is, many actually
buy the idea, get burnt for a few years and refuse to
acknowledge they are being burnt ("if it is mentioned in
textbooks, there must be a reason... it must be good for me..."),
and only then to realize much later... hmmm.... maybe
"data encapsulation" should be done by convention and not by
syntax.

Yes, another thing that I consider to be stupid in C++ is the
overuse of const, or its use at all. Again, generations of
programmers are taught into this thing about usage of const,
and buying into it without questionning.

Python uses references for object parameters in function calls.
It can also return tuples. That's enough. Really.

Keep Python simple. The role of Python is CP4E (Computer
Programming For Everyone.) In Java or C++, you have to type
all the extra stuff about public/ private/ protected/ void/
abstract/ static/ synchronize/ final/ const/... before you can
do something. I know many people that live in that world and
refuse to simplify their lives... well, then again, I also
know people that lives in the Perl world and insist that Perl
is a very readable language. :)

Message-ID: <20000311202916.B8706@magellan.midsouth.rr.com>

Right now, visitors to my site at http://www.centralchurchyouth.org go
through the following redirection:
http://www.centralchurchyouth.org (running IIS)
	to
http://www.centralchurchyouth.org:8100/ (running Zope)
	to
http://www.centralchurchyouth.org:8100/Home/ (the real home page)

This works in Netscape but doesn't work in IE. The user gets all the way
to the third page but it doesn't render. Upon further analysis, all of
the absolute_url calls (like "<dtml-var "stylesheet.absolute_url()">"
produce http://www.centralchurchyouth.org/xxx instead of
http;//www.centralchurchyouth.org:8100/xxx, so the page has a broken
logo, etc.

I think it has to go with the HTTP session between IE and
http://www.centralchurchyouth.org:8100/, but I'm not sure what. Using
wget also returns a correct page.
Surely someone has come across this issue.

[snip]

Having worked with C++, Python, and Object Pascal for a long time, I
tend to agree, with a few modifications:

- encapsulation helps keeping the code self-documenting -- nobody can
accidentally access hidden members;

- it aids documentation tools in that visibility rules can be seen as
metadata -- "source navigator"-type object browsers can categorize
members (methods and data) into their various protectedness; and

- most significantly, hiding data and replacing direct access with
clearly defined accessor methods lets you control access (such as
synchronizing access from multiple threads) and also provide behaviour
-- often data is calculated on demand rather than stored, and often
related objects must be notified when data is changed.

Python doesn't have accessor methods, but uses __setattr__ and
__getattr__() instead, which is less intuitive -- a code browser cannot
easily infer the access interface from the class definition alone -- and
certainly slower -- but also more flexible. 

I'm a big believer in pure-code interfaces, keeping data hidden and
restricting all reads and writes to accessor methods; languages such as
Dylan and Object Pascal fortunately have accessor-method support built
into the language, so referencing an attribute foo.name would actually
be resolved by the compiler into a call to foo.GetName(). Python doesn't
really need this, since its attributes are all dictionary-stored.

Btw, as for private data members that are very specific to an
implementation of a class, Ada95 solves this quite elegantly through
packages, which are similar to C++ namespaces. I don't remember if Ada
has language-assisted accessor method support.

Const is overrated but often useful. Given C++'s absolutely antique
object paradigm -- heap-based objects that aren't garbage-collected,
meaning you end up dabbling with pointers *a lot*, or use confusing
reference-counting smart-pointer template classes that go all over the
place -- I like pass-by-reference better.

I'm absolutely annoyed with C++. This is one reason:

  class Foo;

  class Bar
  {
    Foo F;
  };

  class Foo
  {
    Bar B;
  }

This, of course, won't compile -- the class Foo is undefined at the time
Bar is declared. This means that a class A cannot contain a member of
another class B if B already contains a member of class A, unless one of
them stores the member as a pointer reference. This certainly screws up
any reference-counting smart-pointer scheme, or at least makes it bloody
hard to keep simple.

Readability and verbosity are not the same things. Java is at least an
improvement on C++'s readability, but it is occasionally perhaps too
verbose. But not compared to, say, Dylan, which has keywords like
"required-init-keyword"; in spite of this, it's a great language once
you get used to it.

I rather like Borland's Object Pascal myself. It's suitably verbose to
be readable, strict enough to catch most trivial errors in the
compilation phase, statically-typed enough to perform really well, and
just plain likeable. It doesn't have operator overloading, parameterized
classes, multiple inheritance, or synchronized members, although it does
have interfaces, static, abstract, const, and member visibility
constructs. Here's the above snippet in OP:

  type
    Foo = class;

    Bar =
      class
        B: Bar;
      end;

    Foo = 
      class
        F: Bar;
      end;

(And this compiles.)

Indeed, but do I need to remind you that we're still at version 1.52?
:-)

And as for your argument that OSS boosts language implementation, true
in theory, but sitting down with a compiler and changing it, or building
a compiler from scratch, is a daunting and time-consuming task. I have,
certainly, thought about building a native-code compiler for Python. But
no time right now.

Your comments are well received. I hope I can put my own comments to
shame in the future by committing some of my resources to the Python
effort. As for the types-SIG, I've read through Guido's latest proposal,
and found it so-so; I have some comments about the syntax -- which IMHO
is heading in the right direction, but I feel it's still quite
unpolished, like the new "decl" keyword and the very odd, un-Pythonic
"->" operator. Other than that, it looks a lot like I had in mind
myself.

Interestingly enough, I'm discussing this with Jon Udell on his Byte
newsgroups (go news.cmpnet.com). I'll quote something I wrote in this
discussion, slightly edited for clarity:

<quote>
I can't easily tell Zope that objects of type A refers to objects of 
type B (mutual relationships), and that objects of type B should not 
be deletable as long as an object of type A is referring to it 
(referential integrity). The only kind of relationship Zope knows 
about is containment, a parent-child relationship. There is simply no 
other way for an object to refer to another object.

Consider the case of news articles. Let's say articles should be able 
to hold multiple sections of text, as well as images. Assuming we use 
Z Classes and not Products, two solutions come to mind: Either (a) let 
an article be a descendant of Zope's folder or object manager 
classes, and thus contain any such sub-data as objects -- a design 
which currently is the most useful, but which has its shortcomings -- 
or (b) let sub-data exist as objects elsewhere in the ODB, and have 
string attributes on the article object that refer to their names, 
eg. an attribute "Illustrations" of type "lines" containing image IDs 
such as "mayor.jpg", "airplane.jpg" etc. This is obviously ugly -- 
for example, these image objects could be moved or removed and the 
article object would never know. As for dividing article texts into 
multiple sections (page 1, page 2 etc., with appropriate headings), 
this is obviously pretty simple with scheme (a), but in the case of 
(b), the text could exist in one large attribute, and some sort of 
page tagging system might be enforced -- or we could go all the way 
and do XML. So far, with these solutions, we'll survive. Cracks begin 
to show when we start thinking about organizing authors, 
publications, and document flow.

Zope doesn't provide a framework to solve this things. Equally worse 
is that the ZODB hierarchy is so easily polluted with things that 
don't belong there. You end up putting a lot of objects in the root 
folder because they're needed globally -- and anyone who has used 
Zope will tell you that a folder becomes unwieldy and disorganized 
when it grows past 20+ objects. (Case in point: Personally, several of 
my Zope sites have a root-level Utils folder containing oft-used 
External Methods, because they tend to pollute the whole namespace.)
Zope needs a multiple-root, "multihomed" hierarchy. Z Classes must
be able to exist anywhere, not just in the one Products hierarchy.

No, although that's a clever trick. Hey, do it again! :-)

What you cite above may mirror the effect of an enumerated type, but it
doesn't contain any meta-information about the type itself: That is,
FOO, BAR, BAZ are integers. They will fit into any integer expression
and can be passed to any function taking integer arguments. The function
won't balk if you pass a value from another "enumeration". Another
problem with the above is that there is no way to ask Python to
enumerate the values or names in the sequence, because its values are
part of the top-level namespace -- I don't like that kind of namespace
pollution.

Instead, perhaps, this:

  class Enum:
    def __init__(self, Value):
      self.Value = Value
    def __int__(self):
      return self.Value

  class DeadParrot(Enum):
    FOO, BAR, BAZ = range(3)

  def PetShop(P):
    if int(P) == DeadParrot.FOO:
      print 'It''s resting.'

  D = DeadParrot(DeadParrot.FOO)
  PetShop(D)

...But hardly elegant.

And that makes sense to you? I don't know the historical significance of
tuples in Python -- I know the mathematical meaning, but Python tuples
aren't quite it -- but it smells a lot like an interface that has been
fit to the size of the implementation. A lot like, coincidentally, a
procrustean bed. (Coincidentally because the term has popped up a lot
lately; see the Byte thread.)

I think the idea that mutability as a behaviour is distributed among

(No, it would not -- it would effectively give you both "out" and

The alternative is returning dictionaries or tuples, is it not? Maybe
I'm not thinking in a Pythonic vein. Maybe

	A, B, C = GetABC()

is more immediately grokkable than

	GetABC(A, B, C)   # assuming these are "out" parameters

Well. Sure it is. Damn, I think you're right. ;-)

Subject: [Zope] Calling a Z SQL Method directly
Message-ID: <6rwvn824kh.fsf@franz.stat.wisc.edu>

I am a little confused about how to call a Z SQL Method directly from
within a DTML document or a DTML Method.

The application is web-based access to a bibliographic database.  I
have one Z SQL Method that looks up publications by author names, or
by words in the title, or by keywords.  I set up a search interface to
that method.  I am now trying to modify the DTML Method for generating
a report from such a query.  I have read the Z SQL Method User's Guide
but apparently I haven't understood it completely.

To make things definite I will describe a simple case.  Suppose I look
up one author's name.  The Z SQL Method is called search_author.  The
columns it returns include the "id" for each reference listing, the
"type", the "year", and the "title".  I have also created a Z SQL
Method called return_authors that takes a single argument "id" and
returns the names of the authors, one per row, in the correct order
for the publication.  Another Z SQL Method, return_journal, also takes
an "id" number and returns the title of the journal, the volume and
number, the beginning page and the final page of the article.

While I am processing the results of search_author in the DTML method,
I would like to be able to call return_authors and return_journal
directly.  It is not clear to me how I do this.  I had hoped that I
could use a dtml-in tag to call these methods while I was within
another dtml-in but either I am misinterpreting the effect of dtml-in
or I haven't got the sequence right.  What I was trying looked like

<dtml-in search_author size=50 start=query_start>
 ...
        <tr>
          <td><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
	  <td><dtml-in return_authors start=query_start>
                  <dtml-var name>;
              </dtml-in></td>
              <dtml-in return_journal_info start=query_start>
                  <td><dtml-var title></td>
                  <td><dtml-var vol null=""></td>
                  <td><dtml-var bpg null="">-
                      <dtml-var epg null=""></td>
              </dtml-in>
        </tr>
 ...
</dtml-in>

I was hoping that the <dtml-var id> from within the <dtml-in> loop
would be propagated to a call to return_authors or to return_journal.

I understand that I can use a URL to call the Z SQL Method but I am
hoping I can do it "inline", as it were.

I would appreciate any suggestions.

Douglas,

ZSQL methods can be passed arguments.. e.g.

<dtml-in expr="return_authors(id='123')">
...
</dtml-in>

In the case that the 'id' value you want to pass in comes from REQUEST
or another namespace, you can use it:

<dtml-in expr="return_authors(id=id)">
...
</dtml-in>

The _.render() method will do what you want:

  <html><head>....</head>
  <body><table><tr>...

  <dtml-var "_.render(this())">
  </tr>
  </table>
 ....
  </body>

you need a folder called "import" in the same directory as your zope
installation.  Then go into zope, click "Import/Export" tab at the top,
and enter 'filename.zexp' in the "Import file name" field.

then click "Import".

That should be it!

I'll take a stab at this:

Quantity of data doesn't tip the scales towards Zope or SQL.

If you have small units of data that change frequently, SQL, using a
non-transactional storage like BerkleyStorage, or packing frequently are
all reasonable approaches.

If you have a number of large (multimegabyte) files, the filesystem is
probably the best place for them, with something like LocalFS.  Also
nice because you can have a "real" ftp server serving the files, but
still use zope to reference them.

If your data expresses several many->many relations, a relational
database may be the solution, but don't underestimate the power of
Zcatalog. for data expressing one->many relationships, ZODB rocks.

In your example, I would use the ZODB because emails are always
hierarchical, and use Zcatalog to let people slice & dice it. The
articles would depend on what views you need to put on them and what
metadata you want.

You can also do some super neat stuff with ZODB+SQL, as the very
illuminating 
Zope Question : Virtual folders / URL's thread is illustrating.

I've done some really neat things (like securing the management screens)
with SiteAccess that I couldn't dream of doing any other way.  I've
never seen SiteAccess perform in any unadvertised fashion.

Anything that lets me have less than hundreds of zopes is a good

Let's say I have a TinyTable populated with some data.  I have a DTML
method that displays it all pretty like.  What I do *not* want is
someone seeing the TinyTable itself, so I give "access contents
information" to anonymous, but deny "view".

AFAIK.

This might be possible. I'm checking the IMAP code. Possibly we'll need
to use EXAMINE on some spots instead of SELECT.
Maybe there's a race situation which would explain why it works for some
and for some not.

If heavy copy operations are involved then that would support the race
situation.
We use debian, too, so we'll try to replicate the behaviour here, too.

Cyrus is better scalable and has cached indexes. furthermore mails are
stored in individual files instead of in mailbox files.

Use the DateTime Object, in python:

Py$ from DateTime import DateTime
Py$ DateTime() > DateTime('Jan 1, 1999')
1
Py$

in DTML:

<dtml-if "_.DateTime() > _.DateTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Calling the DateTime object with no arguments means 'now'.  It accepts a
number of different date formats.  I just made this one up and it
happily accepted it.

In DTML, _.DateTime is synonymous with the global value ZopeTime.  So
the Second example is equivalent to:

<dtml-if "ZopeTime() > ZopeTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Message-ID: <20000312145337.B24882@owl.rhein-zeitung.de>

Hi,

we started a new service for our online newspaper, that is served by a Zope
server. (http://rz-anzeigen.de) We currently experience the problem, that the
machine serves really well and also during the high traffic times. But
sometime in the early morning the Zope process crashes. Now I like to know if
it is possible to get some more specific out from the Zope server when it
crashes. Can I activate some kind of logging to monitor this, or something
else that helps me to deal with this? Or is my only option to start the Server
    form the shell and see what traceback I get?

Bye, Oliver

Subject: [Zope] where port num gone
Message-ID: <38CBAFBE.88BF3A23@open.ac.uk>

I have this

root
    ltscimages
        someimage
    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltecimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

IIRC the logic that puts in BASE tags ignores the port number.

It was a simple change (removing an if section) somewhere to fix it.

I did it in old bobo-based app so it may have changed by now.

Jo,
Thanks for your C expertise.  The changes you mentioned were all that was
needed to get the MySQLmodule to compile and the MySQLDA to work.  I now see
the ZMySQL Database Connection in my list of available items in Zope!!! (big
smile).

I will eventually want to get Andy Dustman's MySQLdb connection to work,
because it is multi-threaded.  But for now I will stick with what works,
learn how to tie Zope to MySQL and THEN go for the upgrade to MySQLdb.

Anyway, thanks again for taking the time to solve my problem.

Eric.

Subject: [Zope] Problem with Images
Message-ID: <LOBBJLLPAJLLCKOOOAGFOEADCCAA.gelhaar@compuserve.com>

I've got a problem with the image class. I use Zope 2.1.4 (downloaded from
http://yyy.zope.org/) with Windows 98 second edition.
Let me give an example:
1. I create an image object head_1 and upload an image "cat". Everything is
fine.
2. I upload an other image "dog". Almost nothing happens. The image is not
there. But something has changed: The size properties. What ever I do, I do
not get the right picture, I will see always "cat" but always in different
sizes, the size from the last uploaded picture.
But that's not all.
3. I delete the image object head_1
4. Create a new one, let's say head_2 and give it an image "dog". I see dog.
5. But now, when I rename the image object from head_2 to head_1 I will get
again the old picture "cat".
This scenario is always the same, regardless what I do:
* shutdown the database in between
* clearing the undo buffer
* new installation
* hide the python installation dir
* delete the database

I played around with the lib/python/OFS/Image.py. But I experienced enough
with Zope thus I know Python. What ist wrong with me or the Image class.

Help

I've been asking this list the very same question for quite a while.  There
are a few debug How-Tos that may help, but it's all very dependent on you're
configuration as to how much extra work will be necessary.  Can you give me
more details of your configuration?  What are you using for connection, are you
going through Apache, if so using what service (PCGI,FCGI,HTTP_Proxy)?  

We have several sites up and running with Zope and have found that when there
is /manage activity occuring during a time of moderate traffic we have frequent
Zope restarts, it can't stay up more than 5-20 minutes.  To date I've found no
reliable method of tracking what is causing these, though I've created a bunch
of monitoring and debuging tools to try.  These tools are not written up yet,
but I'd be happy to send out an explaination if you would like.

It is also very easy to create code that will crash or loop the Zope server,
these are easer to find since usually as soon as the object is called Zope
reacts adversly, crashes, slows, etc.  The problem using logs for this is log
entries are usually written post completion.

Good luck.

This is almost certainly because your browser has cached the image.
Try clearing your browser cache.  Or better yet (because sometimes
clearing the cache on some browsers doesn't seem to completely
clear it), try loading the thing from a browser that hasn't
looked at that image before, and you will probably see the correct
image.  At least, that's how it worked for me when I ran into this.

Do you know about STUPID_LOG_FILE?  Put that variable in your
environment when you start Zope, and Zope will write some stuff
to the specified file.  This info may or may not show something
when Zope crashes, but it is worth a try.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

Hi 

I've followed anser's How To on "Apache and ZServer (NOt CGI)"
and now I have Zope served thru Apache via module ModProxy and the
SiteAccess Zope Product.

Fine, But Now I want to make Zserver only accept connections from
a set of known IP address (ie that where my apache server runs)

Any ideas how you do this? I can see there are options to say
which ports it listens on but no mention of restricting the
IP addresses it allows to connect.

Thanks

Message-ID: <NDBBLENPLCPAHKODFHNGAEAPCOAA.morton@dennisinter.com>

Ive been having a similar problem. The problem lies not with Zope, but with
your browser and its cache. As long as you are trying to retrieve the image
from the same URL, your browser will grab the cached image rther than the
one from Zope. I havent delved into this, but I think adding some content
expiry info to the 'view' tab might be necessary. Either that or change your
browser settings.

You can connect to the database from the mysql command line utility?

ZServer does not do this interally, however there is a very secure and
popular program called tcpwrappers that does.  Your system probably
allready comes with tcpwrappers.

How to configure it to work with ZServer I don't know, but it shouldn't
be hard.  Consult the tcpwrappers docs.

If you are using Linux, this job is best done with
the firewall itself (like ipchains.) Otherwise it
is not very secure.

That being said, inside Zope itself, you can put in your
index_html (or equivalent)

<dtml-if "REQUEST.REMOTE_ADDR != '127.0.0.1'">
  <dtml-return "''">
</dtml-if>

Of course, you can return a nasty message, or redirect
the request to some other web addresses by using
<dtml-var "RESPONSE.redirect(...)"> :) If you are using
SiteAccess, you can put a hook at the root folder to
bounce off anyone that you don't like.

The REQUEST variable holds other environment variables
that might be of your interest. You can either use

<dtml-var REQUEST>

to print out the variable content, or simply append
/REQUEST to your URLs when you are browsing a Zope
site:

http://your.site.name/yourfolder/yourpage/REQUEST

Subject: [Zope] Generic User Folder Gotcha
Message-ID: <20000313105937.B4444@bob.sesgroup.net>

Just thought I'd let people know about a small gotcha in the GUF.

If you do not have a user folder in the root directory and then create
a GUF in a subfolder using cookie-based permissions it will lock you
out of that folder.

GUF works fine in this situation if you use basic authentication just
not with cookie based. The problem is that in cookie based authentication
method it never checks whether you are the super user or not. It works fine
if you have a user folder in the root becuase it then goes and checks it.

I tried some code to get around it but didn't really have time to fix it
esp when it is trivial bug/feature? to get around.

Anyway just though this might save some people some time along the way.

Oh and thanks to Zen GUF is a fantastic product !

Cheers,

Benno

Take a look at the dtml-try tag in the dtml documentation.

Message-ID: <B059671903C6D211A0D500C0F0301C792B2697@kubrick.mop.no>

Like so, for example:

	<dtml-var "MyDate.toZone('GMT')" fmt="ISO">

Date-time math is very simple with Zope's DateTime objects. DateTime
supports fractional, C-type clock values -- 1.0 is one day, 0.5 is half
a day, 1 / 24.0 ~= 0.0416 is one hour. So,

	<dtml-var "(ZopeTime() + 1).toZone('GMT+5')" fmt="ISO">

gives you the time tomorrow, adjusted to GMT+5. You can use named time
zones such as "US/Eastern".

Helmut,

I doubt it.  It's probably a username/password/databasename issue.

My suggestion would be to set up mysql to accept a null login (no
username, no password), create a database in there called "test" and
connect with the connection string "test@localhost"

I don't think this is a bug in WU or a concurrency issue, I think it's a
funky design decision in imaplib.py

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import imaplib
>>> server = imaplib.IMAP4('X.X.X.X')
>>> server.login('michel', '******')
('OK', ['LOGIN completed.'])
>>> server.select('Public Folders/Mailing Lists/Zope Folder')
Traceback (innermost last):
  File "<pyshell#8>", line 1, in ?
    server.select('Public Folders/Mailing Lists/Zope Folder')
  File "C:\Program Files\Python\Lib\imaplib.py", line 468, in select
    raise self.readonly('%s is not writable' % mailbox)
readonly: Public Folders/Mailing Lists/Zope Folder is not writable
>>> 

server in this case is a Exchange box.  There is nothing in section
6.3.1 of rfc2060 that says this should fail.  The imaplib authors
however seem to have felt otherwise, which is why there is an optional
second argument to IMAP4.select():

def select(self, mailbox='INBOX', readonly=None):

Passing a true value to the readonly argument will allow you to select
the mailbox, as shown:

>>> server.select('Public Folders/Mailing Lists/Zope Folder', 1)
('OK', ['964'])
>>>

Try the DebugLog, this is an as yet undocumented feature of Zope:

http://www.zope.org/Members/mcdonc/HowTos/DEBUG-LOG

This will show various state transitions of requests.  This helps
pinpoint, for example, if your problem is a ZServer or an application
issue.

Subject: [Zope] Python or C Library error?
Message-ID: <NDBBLBELNHAPHBBCOIFDKEMGCBAA.ewalstad@energywright.com>

Well, I thought I had it working...

I am trying to get MySQL to work with Zope.  I installed ZMySQLDA and was
able to make a connection to a database.  I was even able to make an SQL
method that added records to the table.  However, when I added a method to
lookup a record in the table, I get the following error when I "Add and
Test" it from Zope:

Error, exceptions.ImportError:
/usr/lib/python1.5/site-packages/_mysqlmodule.so: undefined symbol:
Py_InitModule3

This is the same error I got when I tried to install MySQLdb.  That's why I
tried to install  MySQLDA instead.

However, I can't tell if this error stems from C or from Python.  I don't
know much about Python (the book I ordered isn't here yet), but it looks
like the error is starting there.

If anyone has run into this error before, or has a clue as to how to fix it,
please let me know.

OR, if you have a working Zope/MySQL combo and wouldn't mind sending me a
copy of your '_mysqlmodule.so' binary, maybe that would do it?

Thanks,

Eric.

This is kind of a distressing message Tony, we'd very much like to see

Yeah ;) But whats with comparing wether we are between hour xx and hour
yy 
every day? Or even between 0:00 and 1:15 every day...
This comes up with very strange hassle with DateTime() and strings and
int() 
and so on...

Or is there a better way?

I've never used MySQLDA without MySQLdb.

I would try to follow the steps in the howto that deals with installing
mysql (including the steps for installing MySQLdb) in order to get the
thing working.

It sounds like you couldn't compile MySQLdb because you didn't have the
right libraries for MySQL.

I saw that, too, but wasn't sure if it behaves the same, because a few
lines further up if that parameter is true then it uses EXAMINE instead
of SELECT. I haven't made it yet back to the RFC's to check in detail
what the exact difference is between the two. If EXAMINE is OK for 
write operations as well, then that would be fine. But it sounds like
it's intended for following read only operations only. I'll check it
out...

Cheers,
Ryan

DateTime works at one one-thousandth of a second resolution.  Hours and
minutes are no problem.

No hassle that I can see, no more so than any other kind of object that
would do this.

There's mxDateTime, which I believe works similarly to DateTime.  I
don't think one is any 'better' than the other.

Subject: [Zope] RFC: Flaws in Structured text
Message-ID: <B059671903C6D211A0D500C0F0301C792B2699@kubrick.mop.no>

I would like to outline a few problems, based on
observations of real-world usage, with Structured text.
Comments are appreciated.

As much as I like the format, the current syntax is either
too loose, or the transformation logic too dumb, resulting
in text that does not come out quite as expected. There are
workarounds for all such problems, but authors and editors
aren't aware of them, and continually make the same mistakes
over and over again.

Here are a few gotchas:

- Lines starting with the text number-dot (eg., "1.") are
considered to be bullets.

  Problem: In other languages, and sometimes in English,
  this is a valid non-bullet introduction. In Scandinavian
  languages (Norwegian is the language of my country), for
  instance, "1." is an oft-used way of spelling "1nd" or
  "first" ("2." for "2nd" or "second", and so forth). My
  experience is that this occurs frequently.

  Solution: Avoid transforming such paragraphs into bullets
  when they occur adjacently to valid non-bullet sentences,
  and only apply the transformation when the number is
  higher than the preceding paragraph. Validate the number
  itself -- today you can write
  
    43423. Something
    
    24324. Something else
    
  and it's still transformed into 
  
    <ol><li><p>Something</p><li><p>Something else</p></ol>

- Lines starting with dash-space (eg., "- The") are also
interpreted as bullets.

  Problem: As with number bullets, this clashes with non-
  English conventions. At least in Scandinavian languages,
  quotes are often given using a preceding dash. Here's an
  actual example, translated to English for clarity:

    - Pooh, said Rabbit kindly, you haven't any brain. - I know, said
Pooh humbly. 

  Solution: Make this feature optional.
  
- Em dash sequence ("--") usage clashes with definition
lists.

  Problem: People, including me, frequently use an ASCII
  form ("--") of the em dash ("-"), in the absence of this
  character in the 7-bit ASCII character set. (Actually,
  what *I* want is an en dash, which ISO provides.) This
  transforms into a HTML <dl></dl> list, even when the dash
  occurs late in the paragraph.
  
  Solution: Only transform paragraph to definition list if
  the dash sequence follows the first, dot-terminated
  sentence, like so:
  
    This is a definition term. -- and this is the definition
    itself.
  
  Not sure whether this is ideal. It would likely break old
  stx documents. Perhaps a "force literal" control character
  can be introduced, like the "\" token used in Python, Perl,
  C, etc.
  
  Note to self: There ought to be a way to transform such
  poor-man's dashes into en/em dashes, and quotation marks
  to "smart" quotation marks.

- Link transformation into HTML anchors tags is poor, or at
least too rigidly parsed.

  Problem: Some examples of links that do not work:
  
    The document (found "here":http://www.zope.org).
    
    <dtml-var "'This is a \x022link\x022:http://www.zope.org/'" 
      fmt="structured-text">, 
   
  I'd love to give cite other annoying cases I've come
  across, but I don't remember them. ;-)
   
  Solution: Tolerate parantheses, and accept that URLs that
  are terminated with end-of-line. Provide better syntax for
  specifying URLs, such as this:
  
    A product called Zope (http://www.zope.org) can be found
    on the _Zope site_ (http://www.zope.org).
    
  which would be transformed into:
  
    A product called <a href="http://www.zope.org">Zope</a>
    can be found on the <a href="http://www.zope.org">Zope
    site</a>.
  
- Structured text code should not wrap transformed text in
paragraph tags (<p></p>), or should at least make this
wrapping optional.

  Problem: I often display stx in places where a new
  paragraph creates unnecessary vertical padding that
  violates page design -- for this purpose I have been
  forced to write a simple External Method that removes the
  offending paragraph tags. IMHO, this ought to be
  unnecessary.

  Solution: Provide necessary option.
  
- Structured text code not available to DTML.

  Problem: The code is only available to External Methods
  and products. DTML can only get at stx through dtml-var's
  fmt attribute.
  
  Solution: It would be swell to have an _.stx() or
  StructuredText() construct.

Define "top-level namespace"?  This is one of my favorite things about
Python.  You get the behavior you want below *for free*, because modules
are done the Right Way (tm).

'-- spam.py ---
| FOO, BAR, BAZ = range(3)
| 
| class Spam:
| 	def __init__(self,foovar):
| 		self.var=foovar
`--
'-- eggs.py --
| import spam
| can=spam.Spam(spam.FOO)
`--

Alternatively, if eggs.py uses spam.py heavily, and is closely integrated
with it:

'-- eggs2.py --
| from spam import *
| can=Spam(FOO)
`--

I use both styles -- and you can choose!  Clean namespaces, or terse
syntax -- voluntary namespace pollution.  You can even be selective (and
this can really be fun) with expressions like:

'-- eggs3.py
| import spam
| FOO=spam.FOO
| Spam=spam.Spam
`--

if you're heavily using FOO, but not BAR or BAZ in eggs ...

For some strange reason, although they have come under lots of fire,
tuples make perfect sense to me.  They don't seem to confuse new
programmers much, either, since I've been introducing lots of people to
python...

For example; lists used as dictionary keys, if mutable, would have all
sorts of confusing effects.  Class instances, being explicitly references,
don't have this problem; but if you pass a list in as a dictionary key,
change the list... what should happen?

class A: pass
x=[]
q=[]
# you may want to think of that as
# q=copy(x)
# instead
y={}
z=()
a=A()
b=A()
y[a]='a'
y[b]='b'
y[z]='z'
# broken, but to prove the point
y[x]='x'
print y[q]

The same thing goes for strings... I dunno.  Type-defined mutability makes
a lot of sense to me.

Doesn't that just *look* nice?  This is certainly how I'd write this
happening in pseudocode, and I was overjoyed to find that python did it
automatically.

> 	GetABC(A, B, C)   # assuming these are "out" parameters

This style is BAD BAD BAD.  I don't like having my variables manipulated
by functions, if they're mutable... but it would be even WORSE to have the
symbols actually changed!  Nonsense like this contributes to some of the
least readable code I've ever seen in C and C++ ... ugh.  I *wish* you
could return tuples in C++ =)

(The worst part about this is that SOMEtimes, calling a function would
create new variables for you, or reassign them, and sometimes it
wouldn't... ugh.  I don't like it.)

> Well. Sure it is. Damn, I think you're right. ;-)

Glad you see it that way =)

(Tuple unpacking is also brilliant, by the way, for constructs like
	for key,val in dict.items()
)

Subject: [Zope] efficient internal redirect
Message-ID: <38CCA329.9A3754CC@open.ac.uk>

I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

Not exactly. I suggest you read it again. What you and Martijn propose
gives _no_ type safety at run-time. That's just like using constants,
except they're wrapped in a module namespace.

And they do pollute the top-level -- that is, the module-global --
namespace. Let me know when you find out how to enumerate the values in
an enumerated type, and how to convert an enumerated value back to its
name -- and then I might think you're up to something.

Similarly to C++, Python classes behave like namespaces, so you can
avoid pollution by wrapping the values in a class:

	class Foo:
	  FOO, BAR, BAZ = range(3)

and so you can enumerate the values as attributes.

True. However, personally I prefer lexical scoping -- which I hear is
under consideration for Python 3000 -- to the weird three-level
namespace that Python provides. Having to import "global" variables
because the compiler optimizes assignments is way uncool.

I'm not contesting that dictionary keys should be immutable, but rather
that lists and tuples are nearly the same things (*nearly*, but not
quite) with the crucial difference that lists are mutable. Why? There's
no real design here. The only scientific answer to that question is
"Because."

Take a look at my Redirector product, which does this very thing -- it
lets you create Redirector folders which, when rendered, simply redirect
to somewhere else.

It uses regexps to let you apply patterns, such as saying that "/Parrot"
should redirect to "/PetShop" but than "/Parrot/Fish" should redirect to
"/Aquarium". It allows 1:1 redirects as well as many:1 redirects.

Dylan Jay has derived an improved version that supports simpler group
replacements using replace(). Both versions are on zope.org.

I agree with your points, but what is more important for me,
is that the rendered HTML is syntatically correct

* this is an item

* another item

* a third item

currently renders as :

<ul>
<li><p>this is an item</p>
<li><p>another item</p>
<li><p>a third item</p>
</ul>

which is not very slick.. I'd prefer a forward-compatible
list-rendering format, complying with HTML4.0 and XHTML,
looking like this :

<ul>
<li>this is an item</li>
<li>another item</li>
<li>a third item</li>
</ul>

Anybody who has tried to make Netscape4.x understand CSS
without properly closing tags will understand my point..

Thankyou for replying

Whilst this is I'm sure a useful mechanism redirecting
whole folders is overkill for what I need to do.  I have
many links into a tree and wish to have a very simple format
for the external links and an internal mapping mechanism
which maps each link to its real URL.  My question remains.
What's the most run-time-efficient (not development-time-efficient)
way of doing it?  I think you gave me the quickest development
route which is not quite what I was asking.

I agree with theese purposes on Structured Text...

I would like to be able to write simple tables with Structured Text.
Something like :

| FirstName | LastName | Age |
| Olivier | Deckmyn | 25 |
| Guido | Van Rossum | 32 |
| Linus | Torvald | 29 |

That will build a simple table :
<table>
  <tr>
    <td>FirstName</td><td>LastName</td><td>Age</td>
  </tr>
  <tr>
    <td>Olivier </td><td>Deckmyn</td><td>25</td>
  </tr>
  <tr>
    <td>Guido</td><td>Van Rossum</td><td>32</td>
  </tr>
  <tr>
    <td>Linus </td><td>Torvald </td><td>29</td>
  </tr>
</table>

Customization could be done with CSS...

Why can't they be the one and the same? Redirector is fast -- I suspect
the difference in speed between Redirector and something else would be
negigible.

Remember that a Redirector folder is in itself just an index (of
regexps -- it's not hard to wire the lookup so that, if the term is not
a regexp, then it will use a dictionary, which is a lot faster). It does
not need to contain anything, and you need only one Redirector folder to
accomplish what you ask for. Let's say you have three areas that others
link to: Downloads, Registration, and News. First, create a Redirector
folder called, say, /Targets. Then edit the folder's redirection
mappings to look like so:

	From                   To
	Downloads              /Downloads
	Registration           /Snark

Notice that the Registration name maps to /Snark -- this to illustrate
the mappings have nothing to do with the *names*. Now, having done this,
you can access your mappings like so:

	http://www.myserver.com/Targets/Downloads

which will redirect to

	http://www.myserver.com/Downloads

Isn't this what you want?

Shouldn't that rather be

After all, we *are* talking about paragraphs here. I happen to like --

Subject: [Zope] getting port number into URL - was where port num gone
Message-ID: <38CCBEF7.BF8534E5@open.ac.uk>

I'm sorry to ask this again but there must be a way of
getting a port number into a url without being explicit
about the address.  There has to be because absolute_url()
does it inside a tree.  I just don't know what I can use
and the expression syntax to do so.

I have this

root
    ltscimages
        someimage
    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltscimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

.. not necessarily.. the <p>s imply a paragraph of text,
which is not necessarily what is contained in the <li>..

i agree that in most cases the visual result is better with
the <p>, but this should really be taken care of with css.
As far as possible, presentation and content should be
separated...

the <p>s would be ok with me, if we just got the <li>s to
close correctly, but i don't think they should be there if the
reason is purely aesthetic..

Imho closing the <li>s is all we need -- adding padding with CSS works
with the latest browsers, but we still have non-CSS browsers. As much as
I prefer pure, CSS-enriched HTML, it doesn't work all that well in "real
life". Not yet, anyway.

I confess, what you have is a very good idea.  The reason I'm hesitating
is because there won't be two or three areas and its wrong to call
them areas.  They will be single documents and a little bit further down
the
road there may be hundreds of them needed and not in any homogenous
flat structure but at different places in a tree.  Also,
I really do need every last inch of speed out of this part.

Hardwiring your code to use a dictionary looks like a good idea for
the present.

Some questions:

1. does your product redirect back to the client or within zope?

2. assuming it were hardwired as you suggest what would be the runtime
cost over just having folder methods in zope do the redirection?

3. I haven't touched python for 2 years now (though I did use it a lot
then) - I'm very rusty.  Could you supply a patch to hardwire in a
dictionary
instead of the regex code?  Assuming 2. is satis this *could* be a good
answer.

4. still looking for an answer to my orginal q - what's the most
efficient way?

One of myw own - words in single quotes 'like this' should NOT be turned
into code examples.  Most people do not write code examples in their texts.

Or add the whole special_formats dictionary available in PythonMethods to _.

In general, strucutred text needs a complete rewrite to make it extendable
and customizable.  Using the current structure you end up commenting stuff
out and rewriting sections of the code, which is not a very good way of
working.  But I doubt DC have the time for that.

Why not derive a specialized version of my product ("Redirector Method")
that descends from not Folder, but SimpleItem? If each such method
represents only a single "mapping", you get what you ask for.

Of course, if you have plugged your Zope into Apache, then it would be
more efficient to use mod_rewrite anyway.

> Some questions:
>
> 1. does your product redirect back to the client or within zope?

Yes. It forces an HTTP redirect. I don't if Zope is re-entrant; that is,
whether you can emulate symbolic links by passing the request, modified,
back into Zope.

> 2. assuming it were hardwired as you suggest what would be the runtime
> cost over just having folder methods in zope do the redirection?

Not sure if the word "hardwired" is correct here. After all, what I just
described to you in the previous email was not about changing the
product itself -- that's hardwiring -- but changing the parameters to
the product's *folder instance* -- that's Zope. ;-)

What I suggested about using a dict for non-regexp mappings does not
involve any hardwiring, either -- I meant patching the product to
support dicts *in addition* to the existing regexps. Basically in the
folder's management interface you'd simply specify whether a mapping
used a regexp or not.

Runtime cost: You would have to time it. Marginal, unless you're
expecting a gazillion hits.

Let me think about it. I'm pretty busy -- perhaps Dylan is up to the
task, he did the previous patch.

You know, I have a similar problem... I have 6 aliased IP addresses. 
I'm running 3 zopes, at the moment.  All of them have been told what IP
address to use.  The first can listen to 8099 and 8021 no problem, but
the rest of them complain.

if I do -f '' and -m '' everything is fine, but they're all listening to
8080, so what's the gig?

netstat shows localhost:8099 and *:8021, and the same for the other
server that I set to 9023 and 9023 respectively.

Does Zserver listen indiscriminately on ftp and monitor?

But still people do change compilers! People have added garbage collecting
to the Python interpreter, list comprehensions, and there's the whole huge
stackless effort. I'm sure there are more examples in the past, for Python.
Without open source, this wouldn't have happened.

I've thought about it too, and no time either. Maybe we should get

That's indeed a shortcoming in Zope as it stands, but that's not an

That's true, but please note that C's enum is used successfully and

I agree it might be nice to have a more elegant way to deal with
enumerated types. Perhaps as a result of static type checking extensions?

Well, it makes sense to disallow mutable dictionary keys. You asked why
have two kinds of lists, I tried to give the answer. Lists and tuples have
been moving towards each other in recent Python versions, though; I believe
originally only tuples supported unpacking. If there was somekind of
mutability system in place that could replace tuples.

It's cute though, as immutable objects behave like pass by value objects
do (except those darn tuples again, if they contain something mutable like
a list or an instance). I think that's a neat idea.

You have misunderstood what I'm asking completely (probably my fault).
I am using apache and zope, some pages served via the zope-->apache
route, some
directly from Zserver (faster than going via apache) and some just with
apache. Some addresses are already being rewritten by apache - that's
not
a problem.  The mechanism I am seeking to use is just something like

<dtml-var destinationPage>.

Since this doesn't go back to the client between it has to be faster
than going back to the client and doing another request for these
particular
pages (which are in this database anyway).

Please can people reply to my original post without recommending
the redirector product.  I've reproduced the post below in the hope
someone can answer it for me.  Please don't reply telling me how
marvellous the redirector is - yes its a good idea but its not
what I'm looking for here - I'm just looking for some help to
know what's the fastest method and how to code it.

Original post
-------------
I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

> You have misunderstood what I'm asking completely (probably my fault).

If I were you, I'd definitely go over that original post of yours again
and consider how it can be rephrased -- because from what you say, this
is how I see your problem:

1) Pages within Zope
2) External sites or pages that link to these pages
3) You'd like the underlying pages to be separate from the URLs to which
these external pages refer, so that you can move the actual data around.
4) You want this to perform really well.

From this specification, it sounds like, aside from the marginal
performance loss incurred, you should be able to make do by using plain
old HTTP redirection. Did I get any part wrong?

You could use a kind of hub method like so:

<dtml-let Mappings="{
  'Downloads': PARENTS[-1].Downloads,
  'Foo': PARENTS[-1].Bar,
  'Snarf': PARENTS[-1].Smurf.Snark
}">
  <dtml-var "Mappings[REQUEST.Where]">
</dtml-let>

Assuming the method is called /Hub, then you can invoke it like so:

	http://www.andysserver.com/Hub?Where=Snarf

and it will display, in this case, the object "Snarf" in the root-level
"Smurf" container. While this works (you can also use a TinyTable
instead of a dictionary), this has a few gotchas, such as causing
trouble with proxy roles. No HTTP redirects, but not as elegant.

Oh, and did I mention how absolutely marvellous the Redirector product
is? ;-)

Message-ID: <3.0.1.32.20000313085541.0068c54c@bizux.net>

Can anyone give me any insight as to why the below URL doesn't work.

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?id=8185

After the URL is visited the manage screen comes up and tells me "No Items
were specified!" 

So I am a little confused as to why there is no item specified, when I am
sending the 'id' number with the URL, and will the activation of this
hyperlink take me to the manage screen or just delete the object and leave
the user at the page where the hyperlink was requested from.

Best regards, 

-M.

Yes.
Plain old inclusion (like #include in C) would work faster
because it doesn't go back to the client in the same sense
as HTTP redirection.

There is some way of doing this in dtml, I know because
I had something working at one point but I can't remember
what it is.  I do remember it only worked if the objects
that were redirected to (equivalent of included) were methods
not documents.


<dtml-var "whatever.whateverelse.object> gets the right object
but it doesn't get rendered.

This will imply some parameter to define whether you want headers or not
as not everybody uses them. Unless we can come up with some clever (but
visually pleasing in ASCII) format. 

Alexander also mentioned he does not like the <p> elements inside <li>
elements but IMO are required in cases where there are more than one
paragraphs in an <li> element. Unless we default single paragraphs in <li>
elements to non <p>, but then we break consistency.

I suppose a complete rewrite of stx is in order using a more modular
interface. For example I was thinking of one class per structure element
with the appropriate input method to receive the stx text, and a number of
output methods to produce a variety of formats, html,pdf,rtf etc. This is
the approach I followed in the Table patch but it is also slower. The
original stx was designed with performance in mind.

One suggestion I have (and it would be relatively easy to implement) is to
cache the rendered document in a volatile attribute attached to the
DTMLmethod/Document that contains it, together with a simple checksum of
the input text. Then we would be free from the performance constrain at
least to some extent.

The idea being that if a folder represents a virtual host (see the thread 'REQUEST vraible methods'

above rule checks for, and if it matches that in the header, if sets the base path to '/'.

However, if I try and access any folder with this rule in it, I get challenged for authentication
and get 'Authorization failed' no matter what username and password I use, including the root ones!

What is going on?

Would using re (so it can take advantage of multithreading) make up for a
more complicated rendering engine?

This wouldn't work in all cases - consider <dtml-var ZopeTime>, where the
output changes every time it's called.  If an object contains only
strucutred text then you store the rendered text too, and update it every
time the input text changes - the PTK has an object that does this.

manage_delObjects expects 'ids' - which is a list - as parameter. So,
try

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?ids=8185

or:

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?ids:list=8185

No, the user will be directed to the management screen. To prevent this,
you can either create a dtml method or you put something like:

<dtml-if delobject>
  <dtml-call "manage_delObjects(delobject)">
</dtml-if>

into the calling page and change the link to:

http://diis/inventory/outofstock/OOSStorage?delobject=8185

Hmm I hear the new re module of python1.6 is fast .. so a migration to re

If a block of structured text contains dynamic content then you are right,
caching won't work, but in many cases structured text documents contain
only static text. It does not harm to cache unless you have many stx docs
and little memory. I haven't checked PTK yet but in Zpdf Document the
rendered output is cached in a volatile attribute together with a fast
checksum on the input text. Works quite well and ZODB takes care of
garbage collection during object deactivation.

Referring to server side includes, I probably should have put that this
line was an error as well: 

<!--#include virtual="/include/header.html" -->

Subject: [Zope] mange_changeProperities external method
Message-ID: <3.0.1.32.20000313105947.0068de3c@bizux.net>

I have an a form in which the user can edit an instance of a ZClass and
resubmit the data. This data is to be used instead of the data that is
currently listed within the properties of said object.

After submitting the change I get this error:

Error Type: AttributeError
Error Value: 'string' object has no attribute '_properties'

The code that it is referring to is:

def editTaskProperty(self,REQUEST,RESPONSE):
  taskobject = self.taskstorage.REQUEST['task_id']

  for p in taskobject._properties:
    taskobject._setPropValue(p['task_title'], REQUEST['title'])

Can anyone give me any insight as to how the proper method of changing the
properties listed on an instance without the user catching any wind of the
management interface?

Best regards, 

Mark

You can do it in a DTML Method (very similar in an external method too)
like:

<dtml-call 
"MyZclassInstance.propertysheets.Mypropertysheet.manage_changeProperties(REQUEST)">

The reason I was using the external method was to avoid the user from
witnessing any use of the management interface.

This should work, is 'The Right Thing'.

If you are using a DTML Method, then it will be a method *of the
folder* containing the method. DTML method's dont add a namespace of
their own, so <dtml-var title_or_id> is supposed to give you the
folder's title.

No.

I mean that setting a production flag on the zope server and let all error
messages goes silent.

It will be very difficult and troublesome to keep track of all errors. Just
because some one have make a rename on one of my object, or the object is
being modify and thus not available.

Also, are there anyway to remove all the manage things from a production
site?

Are you killing the server between restarts, or closing it politely
with the management interface? The polite shutdown writes an index
file that speeds up the restart.

My development database has 30k objects, and restarts in under 3
seconds.

The call Pavlos gave does not visibly expose the user to the
management interface.  It does assume that the variables to be
changed were supplied in a form that caused this method to be
called, but that can be your own tailored form.  Or if you get
the values some other way, you should be able to pass them as
args to the call.

there are a few of howtos in Zope which use structure text were broken. I
dont remember all of them, but the one with date and sql is (I still can not
read it).

BTW, I  think structure text should be not be used in current way.  I think
a good use of structure text is to use it convert from/to. Instead of
publish.

A greate tool but in bad use.

But what would that look like?  The task requested by the user can't
be completed, so they need to get *some* sort of error message.  Or is
it that you are running with -D and so getting the python tracebacks
in the error web pages and you want to eliminate those?  In that
case, just remove the -D from your start script.

No, but anonymous users can't (by default) access the management
screens.  If your visitors have userids, just don't give them
permission to access the management interface, and they'll never
see it.

Thanks a lot for the info.  Seems that IE 5.x was saving in ISO (windows)

switching to standard ISO format (errr, I guess that's SISO), everything
worked out fine.

If it's a DTML Method, you could do <dtml-var
"whatever.whateverelse.object(_.None, _)">

There is also a _.render method that I've never had occasion to use.

Also, if you want to make things a bit more generic and work somewhat like
the Redirector, you could also do a
<dtml-var "REQUEST.resolve_url(the_new_complete_url)(_.None, _)">

All untested, but will hopefully help you along...

Hi,

I have the following python Class in MyTest module:

import DocumentTemplate

class Test:
	index_html = DocumentTemplate.HTMLFile('test_form.dtml')
	
	def __init__(self):
		... 

	...

	def mymethod(self):
		return 'Hello'

In my DoTest.py module i have:
import MyTest
t=MyTest.Test()


If I run:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t

i get the correct output (a html file with http header).

but if I try:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t/mythod

i get the following error message:
***************************
Status: 404 Not Found

...

  <H2>Zope Error</H2>
  <P>Zope has encountered an error while publishing this resource.

<!--

I really don't know what is my mistake. I'm pretty sure that mymethod is a
method of the Test class. I can also access to the variable index_html of the
Test class, so why am I unable to access Test instance methods this way?

Actually, I also tried the example in the Zen HowTo: The (old) Product API
Tutorial. Is there now another way to call a python class instance method
with the debugger?

If I do the <image src=imagename explicitly I have to fill

Also, is there a general mechanism for doing this sort of thing?

Thanks for this. Only just got round to trying it. For dummies
like me does "re-build" means do "python wo_pcgi.py" again
from the root of your Zope install (under Linux)? (Having,
of course, replaced the lib/python/ZODB/TimeStamp.c file.)

I hope so because I just did it and it seems to have solved
the problem in as much as new News Items in my PTK-generated
pages no longer all have dates of 29 Feb. (I guess there may
be more finely honed ways of just causing a selective
re-build ....)


I note, however, that those News Items that were created with wrong 
dates, still have wrong dates (at least as displayed on 
the Web pages). Perhaps this is a problem that is just
local to the PTK?

Your method does not have a doc string.  ZPublisher will not call a
method unless it has a doc string.

The FTP handler does not accept a hostname argument in it's
constructor.  This is probably an artifact of the medusa code. 
Shouldn't be a hard fix.

The monitor server is hardwired to localhost.  I believe this was a
security decision.  You can hack z2.py any way you like to remedy it.

I'm running Linux 2.2.12-20, Zope 2.1.4, currently with only ZServer

Nope.  Zope does not speak SSI.  It speaks a very similarly looking
language called DTML.  DTMLs 'old' syntax _looks_ like SSI, but it is
not.  It is syntactically different in many cases, and does not support
neccesarily same kinds of tags.

I sugest you read the Document Template Markup Language Users Guide on
the zope site.  It's in the Documentation section.

Subject: [Zope] condional client-side code
Message-ID: <38CD3812.64591827@open.ac.uk>

Ideas please - how to do this.

I'm using zope in frames and need some output to be
condionally there depending on what the window name
is.  The idea is  for client-side code to decide 
whether or not its displaying in a frame and output
a header if needed.

The only way I know to do this is with javascript

"if (window.name=="whatever")" etc.
on the client side.  What makes is messy
is having to hand-process the stuff that's on the
"then" part to put it in document.write() calls.

This is quite messy because there's quotes and all sorts in
it.  It would be nice to write

    document.write("<dtml-var whatever>")

but because of messy chars and returns and so in
in the "whatever" document it doesn't work.  Also,
its really desirable to be able to have "whatever"
in just one place and use it in different ways in
different documents.

My current thinking is - "is there some way I could
process the contents on "whatever" on the fly so that
it would work with document.write?

Any other ways to do what I want?

I believe error code 11 is a segfault, pointing toward a memory
problem.  I just finished dealing with a situation where zserver
was restarting, and increasing the available memory for the
process circumvented the problem.  This may well not be your
problem, but it may be worth looking at.

Is Zope supposed to handle out-of-memory problems gracefully?

For images, you can use:

<dtml-var "imagename.tag(border='0')">

I'm not sure what a "general method" would apply to, but I'd hazard
to guess that any object that produces a tag when rendered should
probably have a similar tag method...

Does Zope leave a core file?  Try 'find -name core -print' from the top
level directory.

Message-ID: <20000313201057.94590.qmail@hotmail.com>

Hi,

Is there any comparison between Enhydra (Java-based open-source
application server) and Zope (Python-base open-source application
server)?

I guess Zope and Enhydra are colliding head-on. :) Can anyone
give a little bit more background to Enhydra?

Zope site used to have a page about comparisons (like with
PHP), now I cannot find that page.

Having worked with Java (and previously with C++), I must say
that I don't have a positive opinion about Java. I know Enhydra
has this "open source" thingy and even tries its best at painting
"worldwide developer hall of fame" stuff, but it seems kind of
corny. I just don't think you can do open source well enough
with a language like Java which was designed by the corportate
and for the corporate.

It's not that Zope is excellent, it's not. But Python's CP4E
(computer programming for everyone) approach eventually will
make it longer lasting than anything else, (especially after
Python 2 comes out) and I just don't see how Java can
survive in the long run. As for Zope, I guess in the long
run it will need a major re-work, otherwise it will lost
the competitive edge.

Message-ID: <001b01bf8d2b$aaf24ee0$0201a8c0@iridium>

Here is my quick intro to Enydra and why I think it is interesting.

Enhydra (http://enhydra.org)
======

Licence : OpenSource.
Technologies : Java Servlets, XML DOM.

Java-based Enhydra has possibly the most interesting take. It uses
JavaServlets to provide content. You give it your HTML file, marked up with
some extra attribute tags :

<HEAD>
</HEAD>
<BODY>
  <P ID=Fred></P>  <!-- a Param tag with ID -->
  <P ID=Jim></P>     <!-- another -->
</BODY>

It then turns this HTML into a Java class with all the tagged elements given
getter/setter methods in the class. It compiles the class.

So now if I want to do something with the HTML fragment above I just create
an instance of MyClass and do things like :

  GetElementJim.SetText('My content for Para1');
  GetElementFred.SetText('My content for Para2');

In essence the Class models a XML DOM tree for the HTML put in so you can
now apply DOM methods to it to manipulate the model.

This neat because :

1. It's in compiled (well, as far as Java compiles) code so is quick.
2. DOMs  kick out "compressed" XML content, all redundant spaces CR/LF pairs
are removed.

Enyhdra also pools DB connections to improve performance.

with a language like Java which was designed by the corportate
and for the corporate.

It's not that Zope is excellent, it's not. But Python's CP4E
(computer programming for everyone) approach eventually will
make it longer lasting than anything else, (especially after
Python 2 comes out) and I just don't see how Java can
survive in the long run. As for Zope, I guess in the long
run it will need a major re-work, otherwise it will lost
the competitive edge.

Message-ID: <38cd5575.3a09.0@jps.net>

Hi Dave,

Unfortunately, I don't have an answer yet.  I am still trying to get the damn
thing to work.  I had ZMySQLDA working until I tried to run a query.  Then I
got the same error that I got when using MySQLdb.

Right now I am in the process of wiping everythin out (short of Linux itself)
and will try a re-install.  I hate doing this because I still don't understand
the source of the problem!

Anyway, I'll keep you updated...

Seems like this discussion should be moved to c.l.p., but ...

I don't understand your objection here. Tuples are immutable "by
design," or "by definition" if you prefer.

What alternative approach would you suggest?

We certainly benefit from having a mutable sequence type designed to
contain arbitrary objects.

We benefit from having a high level mapping type designed into the
language. You agree that dictionary keys must be immutable and you
appear to agree that sequences make useful keys, as well.

Under the covers, we also benefit from Python's design choice that
assignments create object references and the design choice that
dictionaries hash object references, not the objects themselves (which
therefore requires immutable keys).

So what's wrong with Guido setting things up this way and then saying,
"hmmm, this is pretty cool, we just need an immutable sequence type for
use in dictionary keys."

It's a little like the Old Testament Creation mythology. God creates the
heavens and the earth and he sees that it is good. But he decides he
needs to populate it. He finds that one human type isn't enough -- it
gets lonely. So it turns out that in His world, he needs two essentially
similar types, but with a key difference.

So Guido took a rib from the list and made the tuple.  ;)

For my own information, could you tell me how big big is?  I'm running a
database of 60K objects, and when there is a lot of activity on the 
database, the process grows to about 150M.  At around 180M, it
locked up and I had to restart Zope.  I think my server ran out of
available virtual memory.  (I'm moving the database to a dedicated
server Real Soon Now).

I use the attached script to batch-upload directories of jpegs as Photo
objects, so it should be a good start.

I found the source to String.__call__ (in DocumentTemplate/DT_String.py) very
enlightening. This is the same __call__ method that DTMLMethod and DTMLDocument
inherit.


    def __call__(self,client=None,mapping={},**kw):
        '''\
        Generate a document from a document template.

        The document will be generated by inserting values into the
        format string specified when the document template was
        created.  Values are inserted using standard python named
        string formats.

        The optional argument 'client' is used to specify a object
        containing values to be looked up.  Values will be looked up
        using getattr, so inheritence of values is supported.  Note
        that names beginning with '_' will not be looked up from the
        client.

        The optional argument, 'mapping' is used to specify a mapping
        object containing values to be inserted.

        Values to be inserted may also be specified using keyword
        arguments.

        Values will be inserted from one of several sources.  The
        sources, in the order in which they are consulted, are:

          o  Keyword arguments,

          o  The 'client' argument,

          o  The 'mapping' argument,

          o  The keyword arguments provided when the object was
             created, and

          o  The 'mapping' argument provided when the template was
             created.

        '''

You can see that __call__ with no arguments uses defaults of None and {} for
client and mapping, so essentially the template has nowhere to look up
attributes. This is why you must pass these explicitly. Apparently you can also
pass a mapping and keywords to the constructor but I don't think this is
possible from the management interface.

More ZZen is to be found in DocumentTemplate/DT_Util.py. This module contains
the expression evaluation machinery, as well as the code to the special
namespace variable, '_'.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A069@express.sematech.org>

I've put the following in a SQL method, but can't figure out where the count
ends up...

<dtml-in "_.string.split(tool_id)">

tool_id is a string (like 'EXP01 EXP02 EXP03').  For my normal DB activities I
use count-attribute name for the count total, but I can't seem to find out where
the count is stored in this example...  I tried getting the key with
sequence-key, which returned 1, but count-1 returns 0.

I've solved this already with
<dtml-if expr="_.len(_.string.split(tool_id)) > 1">

but this bothers me....  I know theres a better way!

Hmm, a simple test script seems to indicate that sending a child process
a signal 11 does not cause it to dump core.  Of course, it also does not
seem to cause it to return a status code of 11 either.  This might not
be a SIGSEGV, it might just be a coincidence that the return code of the
(crashed) child is 11.  (FYI, there are two processing going on here, a
'watcher' parent and a child, the parent prints the 'Aieee!' when the
child dies.

Does anyone out there know what a python program returning 11 means?

I think both NS and IE default to check for modified content 'only once per

I know that Zope has the capabality to keep up some sort of version
managament system for zope documents.  I have two questions concerning
this.  One, where might I find some more info concerning this.  And two,
what if I want to use my fav editor - say vi or pico...but that's another
war I don't want to start ;)...instead of the window that zope provides.
IF the file already exists in zope, and then I go and make changes in a
separate editor, and upload the file, since I am uploading the file, will
zope keep track of this as just another version of the same file?  Thanks.

The Very New Newbie to Zope,
Jessica

I don't know where the docs are, but I just started using versions
so I can answer this.

In your top level folder, go to the 'add' box and select 'version'
from the items to add.  This will create an object in that folder.
click on the object, and you'll get some management tabs.  You can
'join the version', and you can save or discard changes.  Once you
have joined the version any changes you make will not be visible
to anyone who has not also joined the version.  (Making changes
to an object will lock out any other updates to that object from anyone
not in the version).  When you are satisified that your changes
are working, you 'save' the version, which makes them visible to
the rest of the world. 

Each change you make to an object is committed to the zodb in a 
transaction, by the way, so even without versions you can
go back and "undo" a change you have made using the undo management
tab.  I'm not quite sure about the rules that determine when
a transaction is burried deeply enough in the undo stack that you
have to undo things above it to get to it, but it is still a
very handy feature.

Someone is developing a ZopeEdit program that helps with this.  I haven't
looked at it yet.

Yes, the upload should appear in the undo stack.

Message-ID: <00031317565600.03374@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

I'm trying to make my own pyhton classes and use them with zope, so I tried to
subclass the class Persistent. However, no matter what I try I get always an
error like:
***
Bobo-Exception-Value:
(<class exceptions.ImportError at 80a9d98>, 
'cannot import name Persistent')
***

I have read "The (old) Product API Tutorial", "Create a Boring Product in
Python" and "ZODB" HowTos but I didn't find the exact way to do it. Even
reading the Persistence module doesn't enlighten me too much: it's just the
license and a string.

So I would appreciate if someone could give a clue about how to subclass
Persistent and to which module it belong?

Oscar

If you're trying to import your product into the interpreter, you have to load
the Zope framework first. The Zope initialization is where the Persistent module
is populated.

From $zopedir/lib/python:

import Zope
import Products.MyProduct
etc...

Access Rules are triggered before authentication can be performed, so their
permissions are nil.  If you want them to access anything other than REQUEST
(as you do) you must give them a Proxy role.

A lot of this is actually a question of terminology.  It is true that
Zope keeps previous revisions of objects around.  This is how you can
'undo' them.  However, this is somewhat unrelated to a Zope 'Version'. 
In the case of multiple revisions of an object, we call them revisions,
not versions.

A 'Version' is an object that you can join or leave.  When you join it,
you are given a 'private view' of your entire managment session.  Any
changes you make will not be shown on the 'public view'.  You can leave
a version and rejoin it.  You can commit a version or discard it.  That
pretty much sums it up.

You do not need to use Versions to get the benefit of previous revisions
and undo, Zope does this for you out of the box.

Your question about editors is related to all this.  You can
edit/add/delete object through HTTP using the managment interface, you
can also use HTTP POST and GET methods directly, WebDAV, or XML-RPC. 
All of these methods are based on HTTP (some editors work directly with
HTTP, or use a protocol transported over HTTP like WebDAV).  You can
also use FTP.  Any changes you make with any of these protocols will
cause a new revision of an object to be written, meaning that they can
all be 'undone'.

FTP however does not work with Zope 'Versions'.  You cannot use FTP to
upload information in a Version that you have joined because FTP has no
join/leave/commit/discard semantics.

I have a method that takes a long time on a system that uses a level 2 DA,
therefore it blocks the entire site (it also uses UserDB so everything uses
the DB). How can I put sub-transactions in my DTML to give others a chance
to use the site?

Subject: [Zope] WorldPilot Performance
Message-ID: <38CD82B7.66FDB982@exceptionalminds.com>

Hi,

I've been playing with WorldPilot on my little notebook PC running
RH6.1, and have noticed that when I access my WorldPilot folder, my
processor spikes and stays spiked until I kill my ZServer and restart.

My machine is just only a 233 w/64Mb RAM, but I have never seen Zope
behave this way with any other products. Running a top shows that my
python/ZServer processes are consuming far  more than their fair share
of cycles.

Has anyone else noticed this?

Thanks.

zopistas,

how would I write a dtml_method to render a objects history (undoable
transactions/revisions)?  any insight is much appreciated.  how about being
able to export the objects history (revisions) via XML and then I could pack
and then reimport it into ZODB (or is this complete madness? ) - this way I
can still pack and keep revisions around of specific objects... 

i.e. I would like to keep all objects revisions but need to PACK the DB
(because its overwhelming large) -- what is the way, masters de zope?

many thanks,

Message-ID: <38CD88EC.36D70F86@ep.newtimes.com>

After looking at both Zope and Enhydra I concluded for my purposes that
they really fit into two very different realms.  Both tools
(applications, application interfaces, whatever you want to call them)
fit the bill for developing web applications.  Both tools provide for
HTML/XML markup to easily integrate with web designers. 

Enhydra deviates from here to be more consultant/development driven with
its class file delivery/deployment method.  Where as Zope continues, it
provides an interactive management model, where the web designer can
update an application and extent it without having to have development
support, there is no compile phase that needs to be done before
deployment.

I believe it depends on what your perspective; If you're more
development centric, Enhydra works great.  If you have to interface
developers and designers on a an ongoing basis and want to deligate more
control to designers Zope is the winner.

Well thats my 2 cents.

Message-ID: <m3ya7ms7uo.fsf@wacko.pdx.net>

I've been reading through code trying to figure out what is going on
here, where this message might be coming from.  My current train of
thought is that the 11 exit code being seen is in z2.py is a result of
sys.ZServerExitCode getting set somewhere and z2.py exiting with that
code.

So I've been trying to find where code sets sys.ZServerExitCode and
what I've found is in ZServer.HTTPResponse.ChannelPipe.close.  In this
routine, the value of self._shutdown is assigned to r which then gets
assigned to sys.ZServerExitCode.  

It looks like self._shutdown only gets assigned when
ZServer.HTTPResponse.ChannelPipe.finish gets called and a response
header contains an bobo-exception-type of exceptions.SystemExit.

So I'm guessing now that somewhere this exception is getting set but I
can't seem to figure out why.

Am I completely off base here?

My experience is that returning a large dataset ( about 40Mb ) from a

Subject: [Zope] Problems with dtml-in batch variables.
Message-ID: <00031412082101.01516@localhost.localdomain>

Greetings,

I am using the ever-so-handy next-sequence-* and previous-sequence-* variables
for a batched list.  This all seems to work fine, allowing users to look
through bite-sized portions of the list.

However, there seems to be a problem.  Whatever calculates these values appears
to assume that the numbers are sequential, which, in my case, they are not.

So, whilst i get the correct number of items each time, they overlap when they
shouldn't, and the next/previous limits are reported incorrectly.

The dtml-in tag in question is :

    <dtml-in "sqlQueryHere()" size=4 start=qs orphan=0>

Any comments?

Chris,

Are you saying that realmedia and netperceptions do their stuff
using Zope?  I've scanned their pages and can't find evidence
of that.  Or are you saying to go with a non-zope approach?
Seems like the non-zope way might be more expensive, for
a small site.

I don't *think* there is canned solution to this in Zope, though
I haven't looked at any of the banner products yet.  But in
principle it is simple enough: the page that is responding to
the search query has access to all the search variables, so it
can decide which banner to include based on those keywords.  For
a simple banner list, dtml-if logic would be sufficient.  But
you probably really want it integrated with a complete banner
product.

In about two months I'm going to have to implement this for a
client.  I'm expecting to add it to one of the banner products
if they don't support it already by then <grin>.

I'm not sure what Chris meant, but it seems like you could do what Marc
wants pretty simply using ZCatalog. Just set up a catalog that indexes the
ads by keyword or title that matches the desired search. Then, when
presenting the search results, pick an appropriate ad from the Catalog...

No.  We just don't have a banner ad product that does targeting.

RealMedia does a very good job of targeting.  It's not (terribly) cheap,
but it does have lots of features.

NetPerceptions can help if you spend lots of time and $.  It's not a
banner ad system in itself, but a collaborative filtering engine that
you can produce recommendations with.  This can help in ad targeting. 
It's incredibly expensive.

And yes, I would say to go with a non-Zope approach right now unless
you're willing to put in the time to write an ad targeting and delivery
system yourself.  We'd love to see such a beast, but done properly its a
fairly complex and time-consuming undertaking.  We've chosen to
recommend off the shelf systems for a couple customers rather than
building our own so far.

Is there anyone else who has been having Zope crashes where SQL in related.  We

Subject: [Zope] User Role, Authentication, HTTP
Message-ID: <20000314035606.71539.qmail@hotmail.com>

Hi,

I have the following situation:

(1) I'd like to use Zope's security model, so I can prevent
    unauthorized users from accessing contents in subfolders.

(2) I want to keep user name and password in a database,
    not in acl_users folder. (Basically, I would like
    ZODB to be read-only. So I can't add users into acl_users,
    I have to add users into my own database.)

(3) I don't want to use the pop-up dialog box to enter the
    user name and password. I want to do it through HTTP
    form interface.

So, what can I do?

Is there a way in Python to tap into ZODB Authentication?
I mean, I could create a generic user for the purpose of
ZODB user authentication, and then activate the ZODB generic
user from the HTML authentication. Or is there a way to
add a role to the current AUTHENTICATED_USER, dynamically?
This problem seems common enough that people have probably
addressed it before.

Where can I find more information on manipulating Zope's
AUTHENTICATED_USER?

regards,

Hung Jung

Message-ID: <3.0.6.32.20000313212413.008ef100@pop.dnvr.uswest.net>

I have a few questions as to how to map zope objcts in python, and I'm
looking for help with this particular example.



I am trying to create a python method that will take one argument, a string
variable.  It will then find the people that match and return a list with
each of the person's data.



I have found two methods that come close to doing what I am after.  The
first one returns all of the people data, including all the variables, and
the second one filters out the people I don't want, but only returns the
ids.  I've tried switching aroung the map(None,self.ids) to
map(None,self.data) and I get typerrors from lambda.  

I don't fully understand how this is working or what the data looks like to
the interpreter, but I know I'm close

Can anyone help?



I've got ! these both work ! :

--------

    def peopleValues(self):
        """ return list of people's data  """
        return map(lambda x, p=self: x.__of__(p), self.data.map(self.ids))


    def remote_personlist(self, thisdjname):
        """ returns true with ids to remote people that match
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].meta_type == 'This Kind
of Person', rlist)
        rlist = filter(lambda x,p=self,s=thispersonname :
p.data[x].clientpersonname == s, rlist)
        return rlist

You're absolutely correct.  It doesn't appear to be in the documentation.  The
closest I could find was an offhand reference to 'sequence-length' in the ZQR. 
I just assumed that since 'previous-sequence-size' and 'next-sequence-size'
existed, sequence-size would also.

Did it, in fact, work?

Hmm... have you looked at the Generic User Folder Product?

I think it would solve your purpose. There is also a howto for

I don't think zope should crash if this happens -- but is there any time
when you'd be retrieving data that it wouldn't crash (insert name of your
favorite web browser here, it doesn't matter which one)?

Subject: [Zope] DTMLTemplate product 0.2.0 released
Message-ID: <200003140538.AAA03457@ml.media.mit.edu>

I've just released my first development version of DTMLTemplates.

You can find the distribution at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate

DTML Templates are documents that allow blocks of text to be named and
made available to other documents. The basic building block of
templates is the DTML "block" tag, which can also be used with other
DTML document types. Templates export their blocks. Another new tag,
the "suppress" tag, allows block definition without rendering.

Here are several nice features of blocks and templates that I believe
will greatly benefit the Zope community (several of these items have
come up recently in Zope email discussions):

	* defines libraries of methods in one file,

	* allows structured text formatting in a DTML document,

	* allows pieces of multiple documents to be combined,

	* allows complex web designs created with HTML editors 
          to be used as templates,

	* provides template elements that encourage proper
	  nesting of markup tags.

In short, I think that Templates offer great promise for the Zope
and Zope developers.

This release is a very early one, though.  A construct as fundamental
as this one may need both syntactic and structural tweaks to function
in the most useful way, and only with discussion can we figure that
way out.  Please don't count on this product being stable for at least
a couple of releases.  

I appreciate your interest and feedback.

This is a Zope crash, not a browser.  Zope dies with a NT exception.

I am currently adding this to my BannerClass foundation. I expect to
have this out in the next month or so. As to how well it will work, that
is up in the air at the moment.

<dtml-alert type=semi-vaporware>
"ZBanner System" (or whatever the final name will be) currently is
capable of hit/click tracking, verification of banner validity based
upon time (after, until, or during a date range), a set variable by
management, hitcount, and clickcount (I think that's all of them). It
also has preference capability (ad weighting).

It also supports ad style and type (where style is button, vertical
banner, and horizontal banner; and type is 'integrated', 'remote',
'local').  In the near future it will be able to call ads based upon
keywords passed to it.

So, why is this not yet fully available you ask? The feature I haven't
mentioned yet. Database independance. Basically, I want to get it set up
to where you can store your banners in the ZODB, and RDBMS, localfs,
whatever. So far, I have a good foundation, but need to pin down the API
better. WHen it comes out, I want to include an example implementation
or two. As soon as my test ZServer works properly again, I'll be able to
progress faster.
</dtml-alert>


And now we return you to your regularly scheduled thread ...

Wow, wow wow. :) Thank you very much. I'll try it out!
Seems exactly what I want.

It's funny, I have seen quite a few postings mentioning
about GUF and Generic User Folder before, (never understood
what it was, though,) and I even mentioned in my own message
that I wanted to create a "Generic User." But somehow I just
never made the connection. :)

Hi all,
I'm using Evan Simpsons' XXX-PythonMethods with great results (after 
a few false starts due to my ignorance!). However, in Guarded.py we 
have the following;

# BEWARE OF THE LEOPARD!

# Set 'do_XXX' true to allow creation of XXXPythonMethods
# and ADD A MASSIVE GAPING SECURITY HOLE to Zope.
# DON'T DO THIS unless you use secure connections for ALL OF
# YOUR ADMINISTRATION or are RECKLESS and/or FEARLESS.
# Even if you DON'T create ANY XXXPythonMethods, just turning this
# on will PUT YOU AT RISK BIGTIME!

Of course, I then set
do_XXX=1   :)

I only ever run my Zope servers under a non-priviledged account.

Can anyone explain what sort of leopards I should look out for, as I 
can see that I'd want to use XXX-PythonMethods for a lot more things.

Tone
ps the icon for the XXX-PythonMethod object is way cool! :)

Good evening. We are a student group here at University of California,
Berkeley, and for the past couple of months we have been trying
(unsuccessfully) to get Zope to work with Apache properly. (We are
Residential Computing, a group which provides connectivity and support to
the residence halls at the UC Berkeley.)

The situation is as follows:

Right now, apache has been configured to pass all requests to zope.cgi
except for our personal pages (/about/staff), which a rewrite rule is
directing to a static file system location.

Our problem lies in an internal section of our site. We call it
/internal/.

What we are having problems with is getting Apache to authenticate the
user BEFORE it redirects to /internal/ in Zope. The other snag: everything
under /internal/ is under SSL. One area where we are not certain is if the
require user authentication specs should be in LOCATION tags or DIRECTORY
tags.

In addition to advice, if you have a similar set-up we would really
appreciate a snap-shot of your httpd.conf.

I would like to open discussion on Version access over FTP. Few weeks
ago I have posted some suggestion on this to Jim Fulton, but no
reaction. I know he is very busy and so maybe here I get any
response. Below, plaese see copy of what I have posted to Jim.

Hi Jim,
I have a problem with versions with FTP. I already read your comment in
mail-list and also made little of traffic on the Zope and Zope-dev
mail-lists. After this, maybe I have a suggestion how to solve the
versioning also over FTP and not only HTTP. This problem arised for me,
when I tried to work with versions edditing my DTML code in Emacs.
        I suggest to be version object a container object. The access to
the version over FTP could be determined in URL. (The ID of version
object, to which I want to make changes, must be a part of
URL. Additioanaly, commands for join/leave, commit .. should be also in
URL, just after the ID version.) This mechanism could allow to work with
versions also over FTP. The classical version management over web
interface in collaboratin with cookies will not be changed, the
mechanism to work with versions also over FTP will be an addition. In
addition, in this way, the other people could see the version
('functionality of version') also over HTTP if they know the version ID
and put it in the URL.
        What do you think about this? If there is any other possibility
to solve my problem, could you inform me? 

Thanks in advance,



Could anybody response to this, please.

Evan,

Cheers, gave an anonymous proxy role, worked a treat :-)

I did notice while playing around with this that moving or copying DTML methods that have been set
as site access rules did have some bizarre effects I wasn't expecting. I think when I copied one, it
stopped working, or something like that...as well as some other such wierdities, is this to be
expected?

Chris

PS: What do you, or anyone else for that matter, think of the rule as a solution to the problem in
my earlier post? I don't *think* I need any magic folders or anything else, but I'd like to get a
second (third, fourth and possibly fifth ;-) opinion before I put it into production...

<dtml-if "_.has_key('virtual_host') and REQUEST.environ['HTTP_HOST']==virtual_host">
 <dtml-call "REQUEST.setURL(path='/')">
</dtml-if>

   I'd more interested in fixing fast reload problem. There were some
reports in the list, that after installing SiteAccess Zope sometimes hangs
for a few seconds when you press Reload (in browser) a few times. I can
confirm this behaviour, but I've never realized the problem is in
SiteAccess - I never ran Zope without SiteAccess :)

Hello,


there used to be a way to change the base classes for a ZClass. It's 
documented here:

<http://lists.zope.org/pipermail/zope-dev/1999-August/001288.html>

I haven't used it recently. It worked for me several time in Zope 2.1.1.

Make sure you backup your database before trying it.

Salut Olivier,


Did you solve your issue below? If not, please reexplain what you are 
trying to achieve.

If you want to render one of your ZClass with <dtml-var myClass> you may 
need to subclass "Renderable BaseClass" (available on the Zope site).

Or I am barking up the wrong tree?

Hmmm,

It would appear that a Site Root and a Site Access Rule containing the following are NOT the same:
<dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

as my site access rule didn't work :( (it left the URL, BASEx and absolute_url() unchanged)

The only way I could solve it was to do the following:

Site Access Rule:
<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

And then put an empty SiteRoot object in the folder of each virtually hosted site.

Why did I need to do this? (more out of curiosity than anything else...)
Also why do the SiteRoot objects have to be in the folder of the virtually hosted site? why can't I
just have one in the root folder which gets picked up through aquisition (they're all blank anyway
;-)

And, most importantly of all, why does adding a site access rule prevent FTP access to Zope?

Subject: [Zope] SiteAccess breaks FTP!
Message-ID: <38CE382B.E4088A9E@nipltd.com>

Hi,

I'm trying to sort out the relative URLs of some virtually hosted Zope sites.
In a nutshell, there some sites visible to the outside world as www.site1.com, www.site2.com, etc
These are in /site1, /site2, etc folders off Zope's root.
The redirection is done using Apache's Proxy method, but I need to sort out BASE, URL, and
absolute_url() type things, which I'm doing using the following Site Access Rule:

<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

and blank SiteRoot objects in /site1, /site2, etc.

The only problem is that since I did this, I get the following whenever I try to FTP into Zope
(which used to work fine and which we use quite heavily for content editing with Dreamweaver):

 550 Could not list directory.

Why do I get this? How do I stop it happening? (preferably without stopping using SiteAccess...)

If anyone has any experience with this, I'd appreciate the help...

Chris

I've been trying to compile DCOracle for 8i under Linux and
I'm _really_ not cut out for messing about with C libraries.
I know Anthony Baxter has done it, but I have a strange feeling
he's probably not near a computer right now.

Has anyone else got this working?
If so could you send me your Setup file? (Better yet would be
to get it added to the ones already in the DCOracle package.)

Chris,


I had exactly the same problem as you.

I eventually found it was a bad idea to use the precompiled python version
shipped with the binary package. In fact when I do :

$ python
>>> import _mysql

it works. However, when I do :

$ $ZOPEHOME/bin/python
>>> import _mysql

It doesn't.


So, I think the best thing to do is to bypass the binary python shipped with
the tarball. I'm dowloading the source version to check if it is ok.

I can't get this to work at all:
<dtml-if "sequence-size > 1">
zope complains about not being able to find 'sequence'.  I had solved this issue
before with a let tag <dtml-let size=sequence-size>, but it seems very wasteful
and adds a lot of syntax overhead to the code.  How can I access the sequence
variable in an expression?

Actually, I'm checking to see if I've got multiple elements.  If I do, then I
use IN () in my DB query, else I put in =.  When I split the string, I don't
know if I have multiple items.

Access Rules are designated by name within their container; If you rename
them, copy them, or move them, the new/renamed method will not be a Rule
unless you designate it as one.

Looks good! This is similar to the solution that Digital Creations came up
with, and is better, I think, than my SiteRoot behavior.

> It would appear that a Site Root and a Site Access Rule containing the
following are NOT the same:
> <dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

Was this Rule living in the subfolder where the SiteRoot would have been?

(they're all blank anyway

Location determines the point at which the SiteRoot affects the URLs.  If
they did their internal 'setURL' in the root, all that would allow is
replacing the initial '/' with the path of your choice, when what you want
is to replace '/foo' (or whatever) with '/'.  A variant of the SiteRoot
scheme in which you could say "replace /foo with /" in the root would
require either rewriting the URLn/BASEn and absolute_url code to include the
replacement, or a hook after traversal completes which allowed the
replacement to be done before rendering the final object.  Either would
work.

> And, most importantly of all, why does adding a site access rule prevent
FTP access to Zope?

This is news to me! Prevents how?  What are the symptoms, and does it matter
what the Rule does?

Evan @ 4-am & digicool

So you've confirmed this behavior, and it goes away if you remove
SiteAccess?  Does it matter whether you're using an Access Rule or SiteRoot,
or is having the package installed enough to cause the problem?

[Sorry, I pressed the wrong key with my last message ; so here it is :]
Thanx Alex !

I've been fighting a little with the URL, but I got it  :)

For thoose who would have difficulties (like I've had!) here is the source
(should be zc.py) :

#!/dev/null
#
# (c) 1999 M.T.G. Handelsges.m.b.H.
#
# This module is only an experimental Extension module to play around with
ZClass internals.
#

import string

def fetchzclass(REQUEST,prefix=""):
    rg=REQUEST.get
    PARENTS=rg("PARENTS")
    product=rg(prefix+"product")
    zclass=rg(prefix+"zclass")
    app=PARENTS[-1]
    prod=getattr(app.Control_Panel.Products,product)
    zc=getattr(prod,zclass)
    return zc

def strbases(zc):
    r=[]
    for i in zc._zbases:
 r.append(str(i))
    return string.join(r,"\n")

def show(self,REQUEST):
    "This shows the bases of zclass in product."
    zc=fetchzclass(REQUEST)
    return strbases(zc)

def copybases(self,REQUEST):
    "this copies the bases from class srczclass in srcproduct to dstzclass
in dstproduct."
    src_class=fetchzclass(REQUEST,"src")
    dst_class=fetchzclass(REQUEST,"dst")
    dst_class._setBasesHoldOnToYourButts(src_class._zbases[1:])
    rg=REQUEST.get
    get_transaction().note("Copied baseclasses from %s[%s] to %s[%s]." %
      (rg("srcproduct"),rg("srczclass"),rg("dstproduct"),rg("dstzclass")))
    return strbases(dst_class)

Here is the doc (still from Andreas Kostyrka andreas@mtg.co.at):

Well, install the attached zc.py in your Externals directory. Add
external methods zc_copybases and zc_show (mapped to zc.py/copybases
and zc.py/show) somewhere in your ZOPE. For demonstration I assume
it's in your root folder, and your zope server is called
http://myzope/.

Well, then use your browser to visit the following URLs (this does
more or less exactly what the above python magic does):

http://myzope/zc_show?zclass=YourZClass&product=YourProduct
http://myzope/zc_show?zclass=TempZClass&product=YourProduct

   This shows you the baseclasses of the two Z classes.

http://myzope/zc_copybases?
srczclass=TempZClass&srcproduct=YourProduct&
dstzclass=YourZClass&dstproduct=YourProduct

   (This should be a one line URL.)
   This does the voodoo magic above. And completly without shutting down
your ZOPE, and
   it does even comment the transaction nicely. (Interesting question if it
is undoable.)

And yes, the attached file is twice unsupported ;)
1.) The voodoo is not supported by Digital Creations, so it may change
    at any time.
2.) The external module is not supported by MTG, as its voodoo coefficient
    is to high.

Hi Alex :)

Nice to see that there is at least ONE good guy that looks at my
contributions...

So : Yes and No...

I've seen the renderable ZClass...
but...this is not exactly what I want :

I have two (or more) rendering methods ...
Sometimes I call one or another, depending on the page I want to render it
in...

I wanted to write :
<dtml-var myClass.render_1>
or <dtml-var "myClass.render_1()">


but never works :(
The only thing I've found to be working is :
<dtml-with myClass>
  <dtml-var render_1>
</dtml-with>

pas glop...

So, it's okay to copy a Site Access Rule DTML method to another folder and then set as a Site Access
rule in that folder? I could have sworn when I tried it, the original stopped working too...
...but I was probbably wrong...

Nope... I was hoping just to have one Site Root Access rule that got aquired for each site. Is that
not possible? :S

Evan,

I don't think it matters what the rule does, it's just enough to have one set. It does, however,
matter where it is. I had to remove the site rule in the root folder so people could get on with
their work, but I left one in one of the virtually hosted sites.

FTP access now works fine except in the folder with the Access Rule in it. That said, that folder is
a Squishdot site and so I don't think it was accessible from FTP anyway...

Hope this information helps :-)

-Does Digital Creations know?

-Does it matter and if so : why / whynot?

I do _not_ want to start Linux vs. Linux thread.. but it seems to me that a

Hello,

I am new to Zope, so this might be a FAQ, but my seraches of the Zope
archives and website didn't come up with anything. I have created a Zope
application (phoebe.rider.edu:8080/Athena).
I am using a Z Class with Property Sheets to define the fields for each of
my entries. The entries are created using a form on my Zope site. My
question is, is there any document, instructions, how-to, etc., that can
tell me how to edit the entries once they are submitted?

Is there any way you can pass the connection to be used by a ZSQL Method as a parameter?

I'd like to encapsulate some SQL stuff in a method where the only thing that changes is the database

Since python interprets "sequence-size" to be sequence minus size, you need
to do a namespace lookup to get at the value.

<dtml-if "_['sequence-size'] > 1">

will do the trick.

Corel is more of a desktop version, so I'd say not, while Debian has a Zope
package so it's very easy to install and upgrade.  But I personally use
Redhat (and will install Debian 2.2 when it's released.  And OpenBSD when I
get my CD...).  Truth is that it doesn't matter.  Especially if all you're
running is Zope.  If you're running Oracle or some other commercial software
you'd want a commercial distrib such RedHat or SuSE.

Not really.  Just use whatever you're comfortable with.

Nice to know the trick, though.  Now I just need to find where the sequence-size
is stored as....

This is almost a religous subject but here's my two cents

it depends on your experience and what you want to do.

i've run Zope on Suse6.3, redhat6.1 and mandrake7.0
the differences between redhat and mandrake for a server are pretty
minimal, basically the pentium tuning in mandrakes rpms which are
meaningless in the context of installing zope and python. so for the
purpose of this discussion i'll call them both redhat. 

for automating startup of zope:
i personally found suse6.3 rc scripts to be alot easier to figure out
they have skeleton in /etc/rc.d/ which you copy alter and symlink into
the /etc/rc.d/"runlevel" directories you want to start and stop zope in.

try man init.d (in Suse)

for playing around with experimental stuff:
i would def. have to say go with redhat. if you want to play with stuff
like ZopeStudio(interface into Mozilla). Suse6.3 comes with a lot of
stuff in RPMs on CDs but requires a bit more experience to get stuff
installed from source and most sites don't offer suse RPMs which
generally aren't compatible with redhat RPMs. Suse itself doesn't offer
updates on most of its RPMs unless they're bugfixes for major programs.

 
for locking the box down:
i would go with Suse6.3. a good sys admin could lock either down. it
really depends on your experience from a sysadmin level. suse6.3 has a
pretty nice hardening script that passes SAINT with flying colors.
Bastille Linux is basically a redhat hardening script but i haven't
played with it at all and it tends to lag slightly behind the latest
version of redhat. 

for a minimal install:
i would go with Redhat.

my choice: Suse, but thats my personal bias cause i think its a better
distro. 

as for the other distros: the only other one i would consider seriously
is Debian, cause it has a very nice package management system through
which keeping your system updated is easy.

in summary: i really don't think it makes a difference, just go with
what you know.

This is untested but it should do the trick:)

<dtml-if "_.int(sequence-size) > 1">

as to why this doesn't work 

> <dtml-if "_['sequence-size'] > 1">
>Error, exceptions.KeyError: sequence-size 

i'm on shaky ground but here i think that your trying to lookup
sequence-size in the namespace variable but the batch process variables
aren't really defined in the global namespace.

This gives a key error as well.  To summarize what I'm trying to do:

<dtml-in "_.string.split(string_with_1_or_more_words)">
  <dtml-if "we_have_>_1_items">
   we have <dtml-var what_is_this_var?> items
  <dtml-else>
   we have only 1 item
  </dtml-if>

I can do the > 1 check with <dtml-if "_.len(_.string.split(string)) > 1">, but
it seems I should be able to get to a count-nnn var inside.  Since I'm not using
a SQL statement, I don't know what the variable is named.  sequence-size give a
name error wherever I use it (from the test screen of a SQL query).  <dtml-var
sequence-key> returns the fist digit of the word.

So, the question is, in the statement:
<dtml-in "_.string.split('item_1 item_2 item_3')>
what will the count-nnn variable be named?

<dtml-let numitems="_.len(items) > 1">

Howdy sports fans.  If the San Francisco traffic doesn't double cross

Unfortunately I don't have a URL handy for time, location, etc., but
I'll try and post it when I'm back in the office.

The subject of the talk is, well, Zope, plus a Big Announcement.

I can't comment too much on your problem, your report, although
detailed, still did not show everything, for example, how is it failing?
Does Zope show public pages but never lets you authenticate?

One thing I noticed is that you want Apache to authenticate, then you
try and pass the Auth headers into Zope.  You can't have it both ways,
either Apache authenticates you (and you are quite crippled in this
sense, using the front end web server to do authentication is not
desireable at all, and limits what Zope can do to a great extend) or
Zope authenticates you.  Perhaps I am not completly understanding what
you want to do, but I think you might be tackling too many problems at
once and your conf file apears to be very complex.

First, take out all the Apache auth and SSL and all the other Rewrites
and complexity and just get Zope to work with Apache.  _Then_ add
something else, and get it to work, and so on.  Further, you may want to
consult the Apache docs and inspect the environment that Apache sets up
for PCGI along each step of this process; Apache, for instance, may not
set up all of the CGI 1.1 environment variables in a way that makes Zope
happy when you use SSL.  Or maybe Apache ixnays the Auth header after it
does Auth.  I couldn't tell you either way.

This could very well be a memory error.  It would be interesting to know
if the underlying libraries could handle a dataset this large, in this
case it would not be Zope but the libraries (I can think of no reason
why python couldn't handle a 40MB object, but I can immagine a poorly
written python extension not doing this right, the old ct_sybase module
is a perfect example).  You didn't specify what database you are using.

There is only one reason why I can think of, clicking on the Shutdown
button. 

A quick grep shows sys.exit being called in a few places however, most
specificly in xmllib and pyexpat.  None of these calls set a value of 11
though.

Are you using any XML?  XML-RPC calls?

> Am I completely off base here?

Perhaps, it's a good avenue to look down however.  What I suspect is
that something is happening (like a SIGSEGV) that is causing the OS to
send a signal to the process whose default action is to kill the
process, setting the error code to 11 for some as-yet mysterious reason
(11 has *got* to be the clue however, I refuse to believe that it is
arbitrary, note also that SIGSEGV is signal 11, coincidence?).  A good
exercise may be to run Zope in gdb and wait, when one of these events
happens use gdb to inspect what's going on.  I'm no gdb expert however,
but I was under the idea that it could tell you when signals arrive (or
perhaps stop the process on the arival of a signal...)

I wrote a test script that forked a parent and child just like Zope. 
When I sent the child a SIGSEGV it returned an error code of 332.  Maybe
my experiment is flawed.  

Have you enough time to look that deeply?

To be more specific, it blocks all other requests through that and other
level 2 DAs.  Non SQL related calls and level 3 DA calls will not get
blocked.

Yeah that kinda puts a damper on the whole site... but that's just
because every access is now an SQL related call.

This is not what ZODB sub-transactions do.  Even if you were using a
relational database that has a notion of sub-transactions (Oracle has
'nested transactions' for example) that would not stop the blocking (of
course if you were using Oracle you would be using a level 3 DA...).
ZODB sub-transactions allow changed objects to get flushed to a temp
filestorage so that you can accumulate more object changes then can fit
in virtual memory.  There is no mapping of sub-transaction semantics to
any of the DAs.  In fact, if I remember correctly using ZODB
sub-transactions with SQL methods is Not A Good Thing.  I don't remember
the exact details.

Solutions?  Execute a shorter query or upgrade to a concurrent DA.

Subject: [Zope] More Z SQL head bashing...
Message-ID: <38CE754B.3F7DA16E@nipltd.com>

Hi,

Well, further to my earlier SQL post, here's the code I'm trying to encapsulate, but it doesn't work
;-)
The problem is one of getting a unique, integer, id from MySQL to use as a primary key for an
INSERT. And no, an AUTO_INCREMENT column won't help here 'cos I need to know what the number is
before I do the insert (it generates a reference number, which is used as the primary key, and needs
to be given back to the person doing the submission...)

Anyway, here's the Z SQL Method Code which goes into a MySQL DB connection:

SELECT COUNT(*) as exist FROM sequences WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
<dtml-if "exist==0">
 INSERT INTO sequences SET sequence=<dtml-sqlvar name type=string>, n=0
</dtml-if>
<dtml-var sql_delimiter>
UPDATE sequences SET n=LAST_INSERT_ID(n+1) WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
SELECT LAST_INSERT_ID() as number

When I try to test the method, I get a NameError for exists, which I presume is coming from the
dtml-if. Any idea what I'm doing wrong or other ways of solving this problem?

cheers,

Chris

I had a similar problem I just puzzled through, though I'm pretty new and don't
know the right ways yet :-)

What I did was create another DSQl query (sql_newID) that queried for the new ID
(select max(ID+1) as newID from table) and another sql_exist( select count
*....)  then I used this result, but it had to be within a <dtml-in > tag...

<dtml-in sql_exist>
  <dtml-if "exist > 0">
    <dtml-in sql_newID>
     insert into table (ID, name) values (<dtml-var newID>, <dtml-sqlvar
name...>
    </dtml-in>
  </dtml-if>
</dtml-in>

This worked because I knew the sql_newID and sql_exist will only return a single
value, so the loop only iterates once.  I've never seen the  <dtml-var
sqldelimiter>, though, so I don't know what it does....

Maybe this will help.....

I'm pretty sure now that async_loop is not exiting in my child process
so I'm guessing it is some other type of abort.  I'll try the gdb
avenue.  I'm pretty handy with that, but I've never done much
debugging python or threaded apps so....

I also grepped around the code and looked over every 11, sys.exit and
SystemExit I could find.  This is a real pain.

This looks like it'll work, but there has *got* to be a simpler and more efficient way of doing
it... ;-)

It's from the ZSQL guide, it lets you put more than one SQL statement in a ZSQL method. 
What I don't understand is why the 'exist' variable stops existing... (maybe I should have called it
something else... ;-)

My vote is also for Mandrake. I had troubles with
RH 6.0 and SuSE 6.3 . Switched to Mandrake 6.1, no
problems - works beautifully with also an Oracle 8

seems to have a slight improvement in performance.

Time of day can certainly be done. Shouldn't be that difficult to test
by IP, domain and browser, thoigu I admit I hadn't thought of them.


Basically, when called, a banner tests's it's validity agfainst a set of
rules, and those banners that pass are put into a list. that list is
built using weight, and the weights could be modified at runtime based
upon things such as keywords or other tests.

I have a bunch of really bad Python code sitting around here that tries
to do same.  I can't even remember how it does it.

It's got no docs and isn't even a working Zope product.  I doubt it will
help much.  But I can send it to you if you'd like.

That should work fine.  The only weird detail here is that the *icon* of the
method probably won't update correctly unless/until you make it not a Rule
before copying/renaming/moving it.  That's because the icon change is a
kludge.

Access Rules are *NEVER* acquired.  If they were, you'd have to think about
what they might do in every single contained folder.

Subject: [Zope] getting object given path
Message-ID: <Pine.BSI.3.96.1000314132519.17585J-100000@twirl.bitdance.com>

I know I've seen reference to a function to get an object reference
given a URL path, but I can't seem to find it.  It doesn't help
that I've been up for more than 24 hours trying to get this code to
work.

I'm just trying to update a series of objects programatically.
I have a form working that submits the data for a Catalog
query to select the correct objects.  The dtml-in statement
is working fine as evidenced by just printing the meta_data
Id.  However...

If I do a <dtml-with getobject(data_record_id)>, the 'id' variable
has the value of the id of the folder above the one the Catalog is
in.  Doing a <dtml-var> on the getobject call shows me a
'folder instandce'.  None of the cataloged items are folders,
they are ZClass instances.  Earlier I ran through the whole catalog
using the dtml-with construct and a reindex_object call, and the
reindexing worked fine.  But now if I try to call 
propertysheets.info.manageChangeProperties() I get told that 'info'
does not exist, even though that is definately the name of the
propertysheet.

I'm desperate to get this working for the client.  getpath returns
the correct value, so I think if I can turn that path into an
object I can access the property sheets and get them updated.  But I
also want to know what is going wrong with my Catalog and/or
the getobject method thereof.  I'm not sure where to start looking....

I'm running under Site Access, and I'm guessing that is the source
of my problem, somehow.

Thanks for the reference to the DTML Guide...it has helped a lot.  I have
come across something that I couldn't seem to find an answer to.  I have
the following line in my original code that I uploaded from an

I found this snippet of code for an echo and set, but my attempts at
modifying it to work for this have failed.

<!--#call "REQUEST.set('varName', 'varValue')"-->
<!--#var varName--> 

Thanks in Advance,

Message-ID: <20000314195906.78165.qmail@hotmail.com>

Hi,

I am starting to look into GUF, but the documentation is
not very well done: it's a bit cryptic and disorganized,
and makes too much assumptions on what the user knows.

Where can I find more help/examples regarding GUF?

The How-To in http://www.zope.org/Members/hippy/GUF_SQL_crypt
is not too good, either. Arrghh... give me some more
hints and I'll prepare another How-To, OK? :)

OK, I browsed a little bit about GUF on the mailing list,
and it seems that there are quite a few disasters. Horrible
disasters. Sorry, but GUF seems a bit too inmature.

So, let me come back to the original question again, beside
straight GUF, is there any other way of tapping into Zope's
security model and using a generic user?

Hi Olivier,


This sounds like a namespace issue.

When using the Python quoted syntax I think you need to enclose the namespace:

Could you try this:

<dtml-var "myClass.render_1(_.None, _)">


Here are explainations straight from my Zope snippets:

Note you could also pass additional variables:

Subject: [Zope] What if you can use Zope on development server only?
Message-ID: <20000314203306.46566.qmail@hotmail.com>

     Has anyone used Zope in a scenario where you don't have control of the 
production server?  In other words, I'm in a non-profit organization that 
rents space from a web host.  That web host doesn't have Zope installed and 
has no plans to install it.  I *might* be able to put Zope on my own 
personal Linux server, which would really make that machine like a 
development server.  Does anyone have any experience utilizing Zope in a 
scenario where the development and production servers are separate and the 
production server doesn't have Zope on it?

     I'd like to use Zope because our web site has reached the point where I 
really can't manage it myself (Ok, it reached that point over a year ago, 
but I'm finally frustrated enough to do something about it :).  I'd really 
like to be able to give other people in my organization, especially many who 
aren't ultra web savvy tech-heads, the ability to author content so I'm no 
longer a bottleneck to the site expanding regularly.  Zope looks like the 
best open source option to do this with.  I also considered Cocoon 
(http://xml.apache.org/cocoon/), but I know and love Python and Zope looks 
like it's both more mature and more well-established for this type of 
application.

     I also want to add that I *am* considering changing our web hosting 
provider, but due to other organizational changes in the non-profit it will 
have to wait at least six months (it's lower on my priority list than 
finding a replacement for our office manager, for example :).  I guess I'm 
just curious if there's a way to use Zope in my current scenario, without 
having to change to a web hosting company that already has Zope installed.

     thanks for any help anyone can provide,
     Anthony

But fs/select.c(sys_select) (in the linux kernel) DOES return
ERESTARTNOHAND of do_select returns a negative value.  This is, of
course, not documented in the select man page...  come to think of it,
it looks like the linux kernel returns ERESTARTNOHAND instead of EINTER
because (quoting the source comments) "ERESTARTSYS [instead of EINTER]
breaks at lest the xview clock binary, so I'm trying ERESTARTNOHAND
which restart only when you want to" [block comments are mine].

Fishy.

Well, after more poking around and experimenting, I'm able to make an
strace look like what my crashing server does by following these
steps...

start Zope (z2.py)
wait till everybody starts
attach an strace to child z2
wait till strace output shows I'm in select
send child z2 a SEGV

strace output matches what I see in production
event.log matches what I see in production

Now that I've figured this out, I managed to get ulimit set up so that
I will get a core file the next time this happens.

Let's hang on till I see the core.

I'm also going to play with getting gdb to work nicely.  I'm not sure
why this is failing yet.

I originally tried running Zope at pair.com, where I didn't have root access
to the box. I *did* have the ability to run CGIs and telnet in, however. You
can get Zope running in such a scenario. And, if they're running Apache with
mod_rewrite, you can even make Zope serve up your site's root.

    One note though: many ISPs don't want you to run a long-lived process.
If that's their policy, then you'll run into trouble that way.

    As far as running separate development and production servers, I believe
you can get something going. I think someone made a Product that will mirror
your Zope database in separate files. You'll lose all of Zope's cool dynamic
ability, but you'll at least be able to take advantage of the content
management.

Subject: [Zope] Getting the path of an Object
Message-ID: <38CEB515.DB36129E@globalcrossing.com>

Hey all, hope this one is relatively easy...

Background:
1. I have a zope site with folders, subfolders (possible several levels
of subfolders) and objects in them.
2. I built a simple interface to allow a user (with the correct
permissions) to see the tree. 
3. In the UI, each item (folder, subfolder, object etc) has a check box.
Kinda like the Zope UI


The question:
A user checks an object (folder, subfolder, object etc), how do I get
the path to the object that is checked.

i.e.

FolderA
	SubFolderB
		SubFolderC
			index_html

Suppose the user checked index_html in subFolderC. 
How do I get the path (which would be
FolderA/SubFolderB/SubFolderC/index_html)

The test code I am using looks like this (it's in a DTML Method):

<dtml-var standard_html_header>
<FORM ACTION="WhichFilesToExport" METHOD="POST">
<dtml-tree branches=objectValues>
  <INPUT TYPE="CHECKBOX" NAME="ids:list" VALUE="<dtml-var PATH_INFO>" >
        <IMG SRC="<dtml-var SCRIPT_NAME>/<dtml-var icon>">
       <dtml-var id>
</dtml-tree>
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Submit" >
<dtml-var standard_html_footer>

Using PATH_INFO obviously wont work since it returns the PATH_INFO of
this method and not the PATH_INFO of the checked item.


Any thoughts????????????

Thanks,
DR

R. David,

I think you want 
<dtml-in "Catalog(mystuff=mystuff)">
<dtml-with "resolve_url(getpath(data_record_id_),REQUEST)">
<dtml-call "propertysheets.MyProperties.manage_changeProperties(
           blah=foo
           blahblah=bar
           )">
</dtml-with>

This will change the properties to whatever you want for the instances
found in the above Catalog search (mystuff=mystuff).

All my best,

     Kevin, thanks for the information!  I do have CGI and telnet ability 
with this host, but I'm surprised that's sufficient to run Zope with.  I 
thought Zope would require a tighter integration with the web server (e.g., 
a mod_zope or something that needs to be compiled in so that Zope can catch 
special Zope-intended requests), and that I'd need root to install it.

     Do I have a misunderstanding of how Zope relates to the web server?  Is 
simple CGI access really enough to install and run Zope?  I was basing my 
understanding on the architecture documentation at 
http://www.zope.org/ZopeArchitecture and 
http://classic.zope.org:8080/Information/Components.

>     One note though: many ISPs don't want you to run a long-lived process.

     Hmm... interesting.  I'll have to look into that; thanks for the heads 
up.

     Yep... that's the tradeoff I figured I would have to accept.  I was 
even thinking I'd have to possibly write my own mirroring script, but wanted 
to see if there was a better way first.  Do you remember anything else about 
that product which might help me do a web search for it better (e.g., it 
definitely used the word "mirror", used the word synchronize a lot, etc.).

     thanks,
     Anthony

Well, I can't give it python, that would defeat the purpose of the

It seems to me that Zope maynot lend itself to being frozen.

Has anyone out there frozen Zope and managed it to continue to work?

If you use PCGI, Zope will work in a standard CGI environment. PCGI
(Persistent CGI) keeps Zope itself around in memory so that it does not need
to be loaded with each hit. However, you do pay the "fork tax", because the
small PCGI program needs to run. I don't know a lot about fastcgi, but you
may even be able to do that without root and eliminate the fork tax.

OK.. Two points.

Firstly, my appology.  I mistakenly believed sequence-size existed, since it's
previous- and next- counterparts do.  However, sequence-length aparently does.
(there is a reference to it in the ZQR, and it's also in the source code.)


Secondly, your problem stems from the fact that sequence-length is not a valid
variable name in Python.  you must use

<dtml-if "_['sequence-size'] > 1">

Annoying, yes... but that's the way somebody chose to go.  I don't know why,
but it's there.  In fact, if anyone could give me a good reason why it is this
way, I would be most appreciative.

Message-ID: <20000315001632.8621.qmail@hotmail.com>

OK, I know some of you are out there watching. :)

Here is what I found out you can do to use Zope's folder
security features using your own user info database, your
own login interface, and without using GUF (Generic User
Folder). It's kind of simple, so don't expect too much. :)
Hey, but at least it does not lock you up and send you
into a panic attack. :)

(1) Have your own login interface, and use some session
    management product or cookies to keep track of whether
    the user has been authenticated by you.

(2) Create additional user-defined roles at the root of
    your Zope project. (Click on the 'Security' tab of
    the root folder, and scroll to the bottom.) E.g:
    'teacher', 'student', 'parent', etc.

(3) Create an acl_users folder at the root of your Zope
    project. Inside the acl_users folder, add new generic
    users. E.g: 'GenericTeacher', 'GenericStudent',
    'GenericParent'. Assign non-trivial passwords to them,
    of course.

(4) In your standard_html_header or equivalent, you then
    check against your cookies or session data. If the
    user is a teacher, then call:

    <dtml-call "REQUEST.set('AUTHENTICATED_USER',
                acl_users.getUser('GenericTeacher'))">

Voila! Now you can use Zope's security settings to prevent
people from accessing given folders.

Message-ID: <DBEPIFAAMMDGMCBPNKJCIELOCIAA.dell7000@thot.net>

I don't know if this is do-able, but here goes.  I'd like to do something
like the following:

<dtml-var main_header>
<dtml-var "external site">
<dtml-var main_footer>

I know, this defeats the purpose of Zope to some degree, but in this case
I'd like to include an external site instead of employing frames.  Let's
say, for example, that I'd like to showcase a resource located on another
namespace.

I've tried:

<dtml-var "REQUEST.resolve_url(my_external_url)(_.None, _)">

but I get a namespace error for obvious reasons.  I realize that the
header's <body> tags would conflict with the external resources' and hence,
I'm not banking on anything.  I also looked at Redirector and found it to be
great for redirection within the same namespace, but I'm unsure on its
ability to redirect to external resources (or namespaces).

My dilemma is that I am using Zope to design a site and require Zope's
numerous features, but I need to include a CGI-rendered page within Zope
header and footers without using frames.  Ultimately, I intend to re-write
the CGI as a Zope object, but at present I'm at a loss.

Thanks in advance,

Mike

Subject: [Zope] WorldPilot IMAP folder filenames
Message-ID: <E12V23Q-0005Py-00@under.eng.cp.net>

I don't know if there are any standards here, but I'm moving a TWIG
installation to WorldPilotand am running into some IMAP folder
naming problems.

We have TWIG configured to look in ~<user>/imap/xyz for an IMAP
folder called "xyz".  This (per memory) is consistent with how I
recall other IMAP clients working outside of our use of "imap"
instead of the cannonical "Mail" (historical reasons).  Now, I can
edit WorldPilot's MailListRoot to be "imap", but the problem then is
that WorldPilot then looks for folders in ~<user>/imap.xyz (ie the
file "imap.xyz" versus the file "xyz" in the "imap" directory).

I'd thought the defacto standard was to use a directory and then
files underneath that.  No?  Is there a reason for WorldPilot taking
this tack?  It makes the migration less elegant (we can't let people
switch back and forth)..

why do I need a concept of a sub-transaction. Is there just something that I
can call that will commit all changes up until a certain point and then
begin the new transaction? I realize this will break the transaction model
to some extent but if the method is long and each iteration is indepedent
this seems a reasonable thing to do.

To do the work using a shorter query would mean breaking the method up into
chunks and then having to call it multiple times which is pretty ugly.

Tell me how to get a concurrent DA on NT without breaking the bank and I'll
do it.
So far I have:

- MS SQL server - Apparently sybaseDA will work but havn't been able to
compile it on NT. You need certain files from sybase I believe.

- SQLAnywhere - same problem as above.

- Oracle - too expensive.

- MySQL - No transactions.

- PostgresSQL - Got the NT binaries but can't get it working. Also can't
compile the postgresDA.

- ODBC - Not level 3.

As far as I can tell the above represents all the options I have open to me.

It's not immature, just unforgiving :-) GUF lets get down to the bare
bones of an authentication system. Unfortunately this tends to mean you 
have to build it all up from scratch. 

Sometime RSN I'll finish a the one I'm working on that uses postgresql
and I'll bundle that up as a package for people to use, or use as an
example. Not for a few weeks yet, though.

Look in the download section of www.zope.org for one. The first
question, though - what do you intend to authenticate out of? A
database? LDAP?

Think of it this way: under normal circumstances if someone hostile got full
access to your Zope management interface, through a bug or password sniffing
perhaps, your Data.fs would be toast.  That's what backups are for, of
course.  Put XXXPythonMethods in the picture and your entire Zope
installation, any filesystem areas writable by the Zope-process user, and
any services accessible to that user are subject to abuse.  Some of this can
also be handled by backups, but subtle subversion over a period long enough
to render backups worthless is a much greater possibility.

You might end up as a CPU server for arbitrary Python programs.  You might
not.  LOOK OUT, IT'S BEHIND Y..<glurk>

They had to have *something* positive going for them :-)

Message-ID: <000e01bf8e30$2c24b200$0100a8c0@pinol1.sfba.home.com>

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in
general?

Thanks

I have a problem with allowing clients to download files from a Zope folder.
The HTML tag is as follows:

With "AvB" being the Zope ID in the Download folder. 
There is an acl_users folder on the "some_folder" directory and the user
belongs to the correct group. All sub-folders obtain their permissions from
"some_folder".

When a client tries to save the file, the client gets the following message:
"Cannot copy. Cannot find the file specified."

Any ideas?

Perhaps not, but in my experience, Bete ZOPE products are much more stable than

In the site I am currently developing I send of e-mails with attaches.  From a
quick grep of the MIMETools files, you can see the boundary tag already exists.

Here is a quick example:

<dtml-sendmail smtphost="192.168.1.211" mailto="curtis@umd.com.au"
mailfrom="zope@umd.com.au" subject="Attach">
<dtml-mime type=text/plain encode=7bit>
Here is some text.
<dtml-boundary type=text/plain disposition=attachment encode=7bit

Message-ID: <v04220800b4f4ec979e3e@[134.76.23.157]>

Hello Zopistas out there!

I just stumbled about the threadsafety of different SQL-DAs. I'm 
coming from mod_perl + MySQL so it seemed a natural choice for me to 
also run Zope with MySQL in the background. I'm doing research (= low 
budget) in clinical psychology and have people fill in all kinds of 
questionnaires regularly which I have to store somewhere later. 
Looking at some past messages it seems to me that free and speedy 
MySQL is awfully bottlenecked by MySQLdb and financially-out-of-range 
Oracle rules. But how big is the difference? Does anybody know?

It also came to my mind that I might be missing an important feature 
of Zope: ZODB. For some reason (lack of marketing?) I just didn't 
realize that there is a database behind Zope that I could use to 
store my stuff. Last night I read some documentation but I have some 
questions left open:

Can I access ZODB via TCP/IP socket to retrieve data for statistical 
calculations?

What about performance?

is there an explaination of this situation? or do I misunderstand

REQUEST.resolve_url().  URL should be unurl-quoted.

getobject actually uses REQUEST.resolve_url and getpath, IIRC, so this may
not help.  But give it a try.

Hi Alex...
thx again !

so, half glop...

Strictly using what you gave me didn't work :(

But, after seeking a little, the following works :

<dtml-var "myClass.render_1(myClass,_)">

But I really don't like it ! Why doesn't Zope give "self" itself ? As normal
python methods do ?

Thanx all !

Normally I'd say try,

href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST['REQUEST_URI']">;weblint"
(the new Zope syntax is <dtml-XXX, but you can use <!--#var XXX--> if you want.

But that doesn't work as REQUEST_URI gives a KeyError.
This is weird because other REQUEST variables seem to work. Any deep 
voodoo Zopistas know why?

<dtml-in "REQUEST.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

Hint:
To see all the REQUEST variables tack on /REQUEST to any URL you have 
(only works with Zope < 2.1.4) or put this in a dtml document
<dtml-var REQUEST>

To just get the environment variables;
<dtml-in "REQUEST.environ.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

So your code should work if you do this;
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST.environ['REQUEST_URI']">;weblint"

(If this seems long winded, it's because I'm writing this as I figure 
it out! :)

Hint: Remember that anything inside "..." is a Python expression and 
Python, *not* Zope syntax applies.

>I found this snippet of code for an echo and set, but my attempts at

That should work fine.

<sigh>
Ok, I probably shouldn't use them then.
</sigh>

But (you knew there was going to be a but :). They are *so* useful.
E.g. I've got a XXXMethod that imports the following;
import os, sys, string, mimetypes, stat
import DocumentTemplate
from Acquisition import Implicit
from OFS.Image import File
from OFS.content_types import guess_content_type

setting do_XXX=0 gives me;

<!--
  Error type:  ImportError
  Error value: __import__ not found
  -->

Which is fair enough as the docs on the Zope site say import is 
controlled. Can you please be a bit more explicit and let me know 
*what* I can import? The Python code is a bit over my head...

<compromise>
Would you say that you could use a XXX PythonMethod to debug code 
that is going to become an External Method?
</compromise>

Thanks for the help Evan, it's much appreciated.

You might be able to do something with urllib.urlretrieve (in an 
external method) and feed that back into Zope

*vaguely tested*
def doit(self, your_url):
	import urllib
	fn, h = urllib.urlretrieve(your_url)
	if h:
		fp = open(fn, "rb")
		data = fp.read()
	return data

You'll get junk like <HTML> and </HTML> in it, but it's a start...

I could be talking out of a hole in the top of my head here, but here goes:

If you get Andy Dustmans' MySQLdb Module 
(http://www.zope.org/Members/adustman/MySQLdb). It's designed to be 
thread-safe. I've always taken that to mean that if a Zope request 
does a ZSQL query that uses this module, then if another ZSQL query 
comes along (in a different Zope thread) then it is *not* blocked 
until the first query is finished, but runs alongside the first query.

If I'm wrong on this I would *really* appreciate a correction here.

The Digital Creations people aren't overly keen on MySQL because it 
doesn't support transactions, which the Zope system uses extensively 
(I only use it for 'Undo'). For the sort of queries I have (many many 
SELECTs, few INSERTs, that isn't a major problem to me).

I'd reckon so. Look into XML-RPC as an example. Of course you can 
just construct URLs that obtain the data you need (eg have a folder 
with lots of properties of the form prop_n and get the values as 
http://server/path/to/folder/prop_125) and perhaps use something like 
urllib (Python library) to do some machinations at the client end).


>What about performance?

People seem to reckon ZODB is fast enough. I think it's Python 
limited (but again, I could be wrong here). That's possibly where the 
pystone benchmark comes in; check these out;

180MHz 603e (Linux) = 850 (my home Zope system)
300MHz UltraSparc (Solaris) = 2800 (our production machine! :(
266MHz G3 (MacOS) = 4600
500MHz PIII (SUSE Linux) = 5400
700MHz PIII (Win32) = 10150!! (this is really annoying, this box cost 
1100 quid - the same as the yearly maintenance on our Sun iron :(

I have no idea why those last two numbers are so disparate for the 
want of 200MHz. We'll be putting Linux onto the 700MHz box to see 
what happens there...

I struggled a little with this and I now have it working (in development 
anyway) using an SQL database (PostgreSQL) to hold details of users. It 
seems to me that if you need to store a 'profile' on your registered users 
then this is the way to go. You need to read the README that comes with the 
distribution and also read the SQL How-to you've listed below. This do not 
really explain how to use it once it is set up so I added a 'Tip' at
http://www.zope.org/Members/Lunus/lunus_01

I'm still learning but I haven't found any reason _not_ to use GUF yet.

if you mean  and <dtml-if "(OUTPUT == 'PROENG') and 'MATRIX'">

then it is equivalent to <dtml-if "OUTPUT='PROENG'">

if OTOH you mean  and <dtml-if "OUTPUT == ('PROENG' and 'MATRIX')">

it is same as <dtml-if "OUTPUT=='MATRIX'">


which one did you mean ?

If you are not planning of storing thousands of forms and have them
accessed by many users/per second then ZODB is really a good solution and
it is *easy* too use. For example (in the simplest case) you can design a
ZClass that contains all the required fields and a form for the clients to
fill. A method can instantiate the ZClass in a folder and add the
parameters provided by the customer and thats about it in terms of simple
storage. You can have a method that returns the data in some convenient
format as a text file which you can then input into your favorite stat
package. Or you can get fancier and build an xmlrpc method in your stat
package if it supports xmlrpc (ie if your stat package is a set of perl
programs) and get the data directly into your package, or get even fancier
and incorporate your statistical analysis routines inside your Zope
product, but I am getting carried away here :-) (and yes it is doable, it
has been done and if you decide to take this route I have some PCA
routines in python you might want)

zopistas,

during load testing i often see zope / zserver restart or exiting

i'm doing my load testing with apache benchmark, concurrency level
around 10.

"some_simple_oracle_select" being a simple zsql method.

the system is zope 2.1.4 on a suse linux 6.1 

we're going into production soon and we will have to support medium

Subject: [Zope] more on DTML Templates
Message-ID: <200003151443.JAA14787@ml.media.mit.edu>

Here is an update on DTML Templates, and a more in depth explanation
of how they work.

** Update ** 

I've updated the DTMLTemplate product to allow commenting out block
definitions and importing blocks using keyword arguments to the
blocks() method.  The new version is 0.3.0

Find DTMLTemplate at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate


** More Information **

Yesterday, Jonothan Farr (jfarr@real.com) asked about the differences
between Templates and the var tag.  Here's a short summary.


The Template product consists of the "dtml-block" tag and the 
"DTML Template" document type.  In a normal document, the dtml-block
described below::

   <dtml-block myblock>
     Block contents      
   </dtml-block>                   
                                 
works exactly like the following dtml::
                              
   <dtml-if myblock>
     <dtml-var myblock>
   <dtml-else>
     Block contents
   </dtml-if>

In addition, blocks can be used to insert structured text directly into
a DTML document (see the documentation for details)::

   <dtml-block mytext fmt="structured-text">
    * this is

    * structured text!
   </dtml-block>



DTML Templates use blocks in an additional way: to define DTML Methods
that other objects can use.  If the Template 'templ' contains the
following lines::

   <dtml-block myblock>
    Block contents
   </dtml-block>

   <dtml-block anotherblock>
    Another Block
   </dtml-block>
   Other, extraneous text.


then 'templ' will have two block methods that other documents can
access in this way::

   <dtml-var "templ.myblock">              ->  "Block contents"
   <dtml-var "templ.anotherblock">         ->  "Another Block"
   
Any document can also import all of the blocks of a Template into a
local namespace::

   <dtml-with "templ.blocks()">
    <dtml-var myblock>
    <dtml-var anotherblock>
   </dtml-with>

You can also refine blocks using Templates::

   <dtml-block myblock>
    <dtml-var "templ.myblock">
    with more stuff added
   </dtml-block>

   <dtml-var templ>

yields::

   Block contents
   with more stuff added
   Another block


** How is this stuff useful? **

I created Templates because I couldn't design complex and attractive
web pages for Zope using Dreamweaver.  I was always pulling out little
chunks of HTML and putting them into individual methods.  These chunks
weren't valid HTML documents, so I couldn't edit them individually.
With Templates, I create one document with all the HTML code I need,
and block out regions of the HTML using dtml-block.  I upload the
templates (once!) to Zope, and instantly I've changed the definitions
of all the template's block methods.  If I need to make further
changes, I can do it quickly in Dreamweaver.

Templates really makes coherent web design with Zope workable.

Hope this extra explanation helps.

Don't let me discourage you too much.  If you can isolate your Zope, you're
pretty safe.  That means a private or development installation only.  If you
are the only person allowed to touch the management interface, and you
really bite the bullet and do all of your administration through SSL, you
*might* be safe in production.

Right now, they are controlled into oblivion; I have vague plans to allow
some sort of safe import, but no clear idea what would truly be safe other
than trivial "you can use import as another way to spell x = self.foo"
stuff.

That should work well.  XXXPythonMethods and External Methods have very
similar semantics.

I wouldn't recommend it; Changes in the implementation of the authentication
machinery will break this, probably in the next release.  Even if that
weren't true, this trick would be discouraged.  This sort of thing is
*really* best done at the Python level, in a Product.

Subject: [Zope] questions about zope, netscape web server and certificates
Message-ID: <H0001bac07822848@MHS>

Hello all!

I have been posting questions every couple of months concerning digital
certificates and different types of authorization capabilities.  I think I have
finally convinced some people to look at using zope here at work.

Does anyone have any tips or hints for using Zope with Netscape web server on
HP-UX 10.2?  I don't have any way to test this before I get started, and I need
to have my ducks in a row before I start telling someone else how to make Zope
work (I don't have access to the machine that will host Zope).

I have used Zope on WinNT to display data from an Access database, and I have
played around with Zope on Linux (I did not have time to recreate my Access
database on Linux).

One of the things that I am trying to accomplish besides just trying to get
people to use Zope for more general stuff:

1. I need to allow users to login to Zope to approve requests for items (I am
looking at using LoginManager, Wizards and ZopePTK)
2. I need to use digital certificates for authentication (Verisign has a module
for Netscape web server which allows for certificate lookups to verify that the
certifcate is valid and issued by us)
3. I need to pass through the user information from Netscape so that I can keep
track of the user who is approving a request.
4. requests and approvals/denials will probably be stored in a rdbms, but some
information may need to be stored in zodb for searches

Message-ID: <00031510231600.01040@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi everybody,

I'm struggling with some concepts in Zope. The last one is the
DocumentTemplate.HTMLFIle behavior. I was trying to run the Zen 'The (old)
Product API Tutorial' examples when I came accross with this line of code that
looked strange for me (maybe I don't know python enough):

index_html = DocumentTemplate.HTMLFile('poll2.dtml')
...
p = Poll("What's for breakfast?", ['spam', 'eggs', 'toast'])
print p.index_html(p)
------------------^^^

It worked fine and rendered my form.
But what looked strange to me was to give p as an argument. So I tried
p.index_html: it gave me the dtml file (with &lt; for < and so on).

So fine depending on whether or not you provide an argument the rendering is
different. I tried to read the sources to understand better that behavior.

I read somethings about passing mapping object or keywords arguments. But the
question is:
As p.index_html is a DocumentTemplate.HTMLFile instance why can we
provide it with arguments like if it were a method or if we were instantiating a
class?

Subject: [Zope] Aiieeee!!!! How do I get Zope/Python to produce a core
Message-ID: <m3k8j4xj0e.fsf@wacko.pdx.net>

With my Zope server crashing about 6 times a day, how can I get the
durned thing to generate a core file?

I have this in my start script:

#! /bin/bash
reldir=`dirname $0`
PYTHONHOME=`cd $reldir; pwd`
export PYTHONHOME
STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE
ulimit -c unlimited
ulimit -a
/usr/bin/python \
     $PYTHONHOME/z2.py \
     "$@"

Which produces this on startup:
core file size (blocks)  unlimited
data seg size (kbytes)   unlimited
file size (blocks)       unlimited
max memory size (kbytes) unlimited
stack size (kbytes)      8192

pipe size (512 bytes)    8
open files               1024
virtual memory (kbytes)  2105343

But when I crash with an Aiieeeee error 11, I get no core file.

Box is Redhat 6.1 2.2.12-20.  

I'm able to generate core files from some trashy c code just fine.

Subject: [Zope] newbie - create and call methods ?
Message-ID: <38CFC78F.30634CD9@inpg.fr>

Hello all,

I've been looking in the available zope documentation, listening to
this list, looking in the archive of this list (BTW : are you planning
to add a keyword search ?)... That is to say that I'm used to
searching for the info about open source OS and applications, but I
have to admit I'am almost discouraged using Zope as the doc is really
scarse compared with what is usually found. 

So, sorry, I post my newbie questions :

I would like to create a method to generate a link (href) with a
leading image and text formatting, and so on. I'd like the method to
have two arguments : the name of the link and the URL.

How do I create a method with arguments ?
How do I call a methods with arguments ?
Do I mistake attributes (for docs but not for methods) and arguments ?

If you have pointers to documents I haven't found that...


Thanks in advance,
Greetings,
Eric


PS: Here is what I tryed:
--- DTML method "meth_link"
<h2>
  <dtml-var img_puce_paragraph>
  <a href= "<dtml-var link_url>">
  <dtml-var link_name>
  </a>
</h2>

--- in an other method
<dtml-var name="meth_link" link_name="foo" link_url="la_url">

--- Zope error
Invalid attribute name, "link_name", for tag <dtml-var
name="meth_link" link_name="foo" link_url="la_url">, on line 6 of
txt_user_content

Subject: [Zope] acl_users and differing behaviour with Netscape/IE
Message-ID: <JLEIIKFACBHJPOBKDLODGEEBCAAA.alexander@limi.net>

Hi.

In our development, we stumbled over some behaviour that caused us quite a
headache for a while. We managed to find a less than elegant solution, but
it works for now.

The case is this:

We have the following structure (greatly simplified :)

 rootfolder
  |
  |-images
  |
  |-artists
  |  |
  |  |-acl_users
  |  |
  |  |-Artist1
  |  |-Artist2
  |  |-...etc


As you can see, we have separated the "acl_users"-folder belonging to each
of our artists into the "artists"-hierarchy. All images we use are located
in "images", under the root folder.

The problem appeared when we used DTML similar to the following inside the
artists-folder:

<dtml-with images>
  <dtml-var picture>
</dtml-with>

In IE, this would work just fine, Zope got the "picture" object from the
"images" folder and displayed it - no problem. But with Netscape and
Mozilla, we got authentication problems. It seemed as though Netscape
insists on sending the authentication request no matter what, and is
actually denied access to material that can be read by anybody (ie: the
objects in our "images" folder).

As far as we can see, this is a result of us having an extra "acl_users"
folder in the "artists" folder. Thus the logged in artist is not a user in
the root hierarchy, but only from "artists" and further into the tree.

We've solved this problem temporarily by putting duplicates of the images in
the "artists" folder.

My questions are thus:

1. Should we move the "acl_users" folder to our root folder? If possible, we
would prefer separating the artist users into their own folder, to avoid
clutter. But they should be able to access the rest of the site, like any
anonymous user.

2. Is this a problem with the way Zope authenticates users? Shouldn't users
that don't authenticate correctly at least have access to the content
readable by anonymous users? Or have I done something terribly wrong? :)

You see, we plan on having a "listeners" folder too, where we are going to
store individual listeners' preferences (what artists they want to be
notified of, what music categories they prefer, etc) - and I assume we will
run into the same problems here - users being authenticated only in the
"listeners" folder and below. They should be able to browse the normal web,
however, and add artists to their notify-list. Does this acl_users have to
be in the root user folder too?

Please CC me, as I don't have access to the list at the moment.

Regards,


Alexander Limi.

In the beginning, there was DTML.  DTML did not have expressions as was
designed to look very much like HTML, so names like sequence-item were
chosen.  Later on, expressions were added.  Names like 'sequence-item'
were obviously not going to do, because in a python expression it looks
like a subtraction.  So, the DTML namespace was given the name _, and
given a mapping interface which allowed you to look up names in the
namespace.  Thus was born _['sequence-item'].  _ is a mapping like any
other.

It's really not that bad, just kinda ugly.

WorldPilot properly displays the mail in my "Inbox" which is located at
"/var/spool/mail/sbaird" on the server. I can create new mail foldersrs
from within Worldpilot, but I can't access them from WorldPilot (I can
from other IMAP clients). The mail folders created are placed in

directory mapping issue but after reading everything I can I can't
figure it out. Any help would be appreciated.

The Python DB API spec 2.0 talks about different levels of thread 
safety. MySQLdb has threadsafety level 1 (= threads my share the 
module but not connections), the ORACLE db has threadsafety level 3 
(= threads may share the module, connections and cursors). I wonder 
what that means in % performance gain in high traffic situations. I 
have no idea where the different levels of threadsafety kick in. Any 
experienced users?

I was rather thinking of connecting directly to ZODB (in a kind of 
server mode) via TCP/IP - not via Zope. But I guess that's an 
aberrant thought that would rather be applicable to connecting to 
ZEO. Still I feel like I'm only beginning to understand but in about 
two weeks the new production site must be ready running zope ;)

Actually I'm not planning anything except to be prepared. I'm only 
starting and have no idea what I will end up with. So of course I am 
looking for a scalable solution. From what I've learned from the list 
scalability seems to be a weak spot of Zope (while e.g. the latest 
Enhydra includes a failover solution). I have no idea how much ZEO 
costs. (People from DC could you help here? I couldn't find a price 
on the website.)

I tried to understand ZClasses and read the documentation a couple of 
times but it didn't help a lot. So now I'm using Python classes which 
is very easy (maybe only because it's better documented). Can you 
e.g. simply add a dictionary or a list of dictionaries to a ZClass 
and access each element individually?

Would be nice if I could get back to you some time later to talk 
about the PCA. :)

Subject: [Zope] Need help with site structure
Message-ID: <NDBBKGBPJMFODAAFNMKEGECMCAAA.mduvall_22030@yahoo.com>

I'm setting up a Zope site, and would like to know if the approach described
below makes sense. I imagine this is a no-brainer for the more experienced,
but I'd appreciate some feedback so I don't go too far afield. Thank you!

In a nutshell, the site will give customers the ability to run reports
against application data that we're hosting for them. There will also be an
area for developers to log on and tweak parameters of the hosted app.

User Management
---------------
To keep the user accounts organized, I'd like each customer organization
(say, ABC Corporation) to have a folder that contains an acl_users folder.
I'd merely prefer to look at a few users at a time instead of seeing them
all together.

When a users logs on, I'd like that user to have a role of custUser,
custAdmin, or custDeveloper. I'd define these roles at the root. I'd also
like the user to acquire (if that's the term) properties of the customer
account, such as customer ID, so customer ID would be a property of the
customer folder(?).

So folder-wise there'd be;
root/customers (containing...)
root/customers/abc_corp
              /...
root/customers/xyz_corp (each with an acl_users folder)

Site Content
------------
This side of the site seems straightforward. The user's role will determine
what's visible/accessible, and the user's acquired customer ID will
determine which application data can be included in reports.

root/mysite (will contain content sub-folders, such as...)
root/mysite/eggs
           /spam
           /reports
           /developers (custDeveloper role required for access)
           (more content sub-folders)

So the question is...
---------------------
My main question is the user authorization / acquisition piece. How do I run
username and password through the contents of the root/customers folder?

If the folder layout described above makes sense, is this authorization
piece a job for a ZSQL Method, for GUF, or for both? Last week's "virtual
folders / url's" thread provided interesting info ZSQL Methods.

Also, any comments about holes or vulnerabilities in this approach are
welcome.

Thank you.

Mitch Duvall

Subject: [Zope] Zclass subclassing Image - how to manage uploads?
Message-ID: <38CFD0D8.B5391DC8@funcom.com>

I've seen numerous postings about this, but so far I have been
unsuccessful in successfully subclassing the Image with my own ZClass
(called VProduct for this case). Here's what I have managed to do:

* Create my new VProduct ZClass with Image as a base class
* Add a couple of new simple (string) properties to VProduct
* Modify the VProduct_add and VProduct_addForm methods so that my new
properties gets asked for and filled in (and using the system clock to
generate  unique id's)

This seem to work great, and I can move about in the Zope filesystem and
add instances of my VProduct class as I want to.

I have not been able to successfully integrate the file upload feature.
What I have done is:

* Add an input file <input type=file name=file> in the addForm method
* Putting a file name in this field and pressing submit button

From here I am not quite sure what to do with the image, but from
browsing earlier postings about this, it seems to have something to do
with calling manage_upload one way or the other.

In the VProduct_add method, I have the following special code:

<dtml-call "REQUEST.set('ts', ZopeTime ())">
<dtml-call "REQUEST.set('id', _.str(_.int('ts')))">

The above code generates a unique id for my VProduct instances, and this
works fine.

Inside the automatically generated:

<dtml-with "VProduct.createInObjectManager(REQUEST['id'], REQUEST)">

further down in the VProduct_add method I have the following stuff:

  <dtml-call "propertysheets.Basic.mange_editProperties (REQUEST)">

that code should take care of modifying the properties of my VProduct
instance (and assumes I guess that the input field names match the
property names). This seams to work great.

Right before the "propertysheets..." line I have tried adding the
following:

  <dtml-call "manage_upload(REQUEST['file'])"> 

It does not generate an error. But it does not seem to manage the upload
part either, since my VProduct instance gets the content_type
"text/plain" (instead of image/jpeg which is the right type for the jpeg
file I try to upload). And when I try to "view" the VProduct instance, I
get a simple <img src="91231912" alt="sometext"> tag which displays like
a missing image in a web browser (no wonder since the content_type is
wrong). I have tried manually setting the content_type to "image/jpeg",
but the image still does not display correctly. My guess is that the
image never got uploaded.

Any ideas on how to handle the upload properly? I've done some 30
searches through the list archive, without any clear answers to how the
image uploads are handled (or should be handled). I've looked carefully
through the howto's but have not found anything.

Any help would be appreciated.

What I know is that you have to use Named Parameters in method

ex:
myFunction(url, image):
    return '<A HREF=%s><IMG SRC=%s></A>' % (url, image)

and the dtml call looks like :

<dtml-var "myFunction(url='http://www.zope.org', image='logo.gif')">

I am not sure of all...But I think it is the "spirit"...

You don't.  But that's what you were asking so that's what I was
answering.

I don't think the problem is that a transaction needs to be commited,
the problem is that the DA is engineered to block until it completes the
task at hand.  Even if you did call get_transaction().commit() from
python or an external method or whatever, I don't think it would unblock
your call.  You can try it, of course.

I don't know if we have immediate plans to bring the ODBC DA up to level
3.  Probably not any time soon unless it is a customer requirement.

Another option is to threadsafe the ODBC DA yourself.

I know, I know. :) But how otherwise do I get you people
to come out from hiding without posting a hack like that? :)

GUF has problems and we have to face it. If a product takes
a few days to install, if a product locks newbies up and send
them into panic attack, it has problems. Please just look
up past postings in the mailing list... headers like "Bad...
very bad" and "GenericUserFolder has locked me out" are
just heartbreaking. :)

If I have time I'll find something better, or make something
better. :)

Evan:

(1) When the the next version of Zope coming out?
    It fixes a tiny bug that I reported. :)
    Will it have a native feature like SiteAccess that
    you have mentioned before?

(2) Could you describe briefly how the traverse machinery
    works in Zope? I'd like to take a look into it. Which
    Python files are involved?

regards!

The boundary tag is implemented in the MIMETools product.  Because it is
only meaningful in the context of the mime tag, I did not explicitly
list it in the readme.

I'm not certain if the MySQL DA is level 3 (threaded) or not.  I am
certain that MySQL does not support transactions and Zope does.  What
this means is, if you call some SQL and later on an error occours, Zope
will "roll back the transaction" and discard any changes you made in
Zope.  If Zope is used with Oracle, Sybase, ODBC, Postgress or any other
database that supports transactions, then those databases will
synchronize transaction commits and rollbacks with Zope.  This means
that your data is allways consistent across databases, which is a good
thing.

This may not effect you.  Your database may be entirely read only, in
which case it's not a problem at all.  Just keep in mind that you are
missing an important piece.

Keep in mind that this is not an _relational_ database.  It's an object
database.

Yep.  You can access the ZODB through HTTP, FTP, XML-RPC and WebDAV. 
That's really what Zope is, it's a network aware application on top of
an object database.

The question is really too vague to get a specific answer.

Well, it's syntactically correct.  Whether or not it does what you want
it to do we can't tell because you didn't say what you want to do.

The expression "'PROENG' and 'MATRIX'"  will _allways_ return 'MATRIX'. 
So 'OK' will only be rendered if OUTPUT == 'MATRIX'.  In fact, this:

<dtml-if "OUTPUT == 'MATRIX'">
  OK
<dtml-if>

does exactly the same things as your code.

There apears to be a segment violation somewhere in Zope which was

Subject: [Zope] Zope and enterprise data access
Message-ID: <4.2.2.20000315131747.00ba5600@saladin.aisys.com>

The company I work for is starting to get more requests for web sites which 
need to have access to enterprise data.  We have several Java people on 
staff and most of these projects are currently being done (or planned to be 
done) using JSP/Servlets and Enterprise Java Beans.  The problem that I 
have with this solution is that there is very little in the way of content 
management available in this environment, without rolling your own.  What I 
would really like to be able to do is build the client interface using 
Zope, so I can easily blend static content, dynamic content and content 
management, with access to enterprise data.  I know that Enterprise Java 
Beans are accessible via CORBA, so theoretically it should be possible to 
access this data through Zope/Python.

My basic question is this, is there anything available (free or otherwise) 
which would make it fairly easy for Zope to interact with something like 
Enterprise Java Beans?  Are other people trying to use Zope in an 
environment where access to enterprise data is important?  If so, are there 
other solutions to this problem?  What I would really like to be able to do 
is use Zope in combination with a DBMS to build smaller systems, but when 
the need arises, I would like to be able to scale things up to allow for 
distributed data object access.

Any thoughts, suggestions or comments on this subject?

Thanks.

Hmm.. unfortunatly there is no good way to do this from DTML except to
use manage_FTPget().  Yuk.  This lack will be fixed in the near future
when we re-do alot of the Zope interfaces.  Currently we are in the
middle of documenting all of the existing interfaces which obviously
must come first.

The Splitter removes numbers.

You can create your own kind of splitter and replace Zope's (note that
Zope's splitter is written in C, and is found in
lib/python/SearchIndex/Splitter.c) you can write yours in C or Python.

I have not touched the authentication machinery yet so I must rely on
other Zopistas efforts. There is a LoginManager which is part of the PTK.
Seems to be well thought out, and it seems to provide a very general and
broad solution to the authentication problem, but I have no idea whether
or how it works.

Another useful add on is for GUF to ship  a complete example of its usage
based on standard Zope objects (Folders etc). Maybe as an exported
folder that the user can optionally import.

I know that you can use the dtml-in tag to iterate over a sequence, but
I want to know how to create a sequence? If, for example, in Python I
had:

foo = [1,2,3]

What would I have to do to get a sequence like that accessible from

I would solve this in the submit action by doing a select for the data before
doing an insert.

Example:

(form_html)

<form action="submit_html" method=post>
....
</form>

(submit_html)

<dtml-in select_data>
<dtml-if sequence-start>
<dtml-var error_message>
</dtml-if>
<dtml-else>
<dtml-call insert_data>
</dtml-in>

Dan,

It's gotta be a connection string or username/password problem as
defined in your interfaces file.  Are you sure the port number of the
remote server is correct in the interfaces file?  You can use isql from
the box that Zope is on to connect to the remote Sybase server?

Chris
First off let me say that I have searched the Zope archives.  I finally
got my sy_occ to compile and I have the SybaseDA Product installed(on
Linux).  When I try to add a new connection using the new DA I get the
follwoing error.  I have set up my interfaces file using dsedit and am
using this as the DSN in Zope.  Also I am trying to connect to a remote
Sybase server.  I am able to able to connect to the remote server using
PowerBuilder ODBC on Windows.

What am I missing?

"Invalid connection string: database: sybase, password: generic, server:

Dan,

You need to install the Sybase client libraries on your Zope machine to
use the SybaseDA.

For more info, please contact the Zope mailing list at
http://www.zope.org/MailingLists

Thanks!

Hello,

How can I make different output from one document?
Would XML be a solution?

I guess I'm confused.  I can't get to the actual jpeg image?  Here's what I'm
trying to do.  I want to create a form to upload data.  This data can be off any
type.  The data is stored in an ODBC database table along with it's mime type.
So, on the upload action form, I need to 1)  get the mime type and 2) get the
actual data.  Another part of the site mails off these items as attachments.
I've heard that the mime type should be uploaded along with the data, I just
don't know how to get to it.

You have a few (untested) choices:

1) Put the following in a DTML Document or Method:

     <dtml-call expr="REQUEST.set('first_sequence', [1, 2, 3])">
     First:<br>
     <dtml-in first_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

     <dtml-let second_sequence="[1, 2, 3]">
       Second:<br>
       <dtml-in second_sequence>
         <dtml-var sequence-index>: <dtml-var sequence-item>
       </dtml-in>
     </dtml-let>

2) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Tokens". Give it the value "1 2 3". Put this as the document
   source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

3) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Lines". Give it the value:

     1
     2
     3

   and put the following as the document source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

4) We could make a Python base class
   (lib/python/Products/MyClassBase/MyClassBase.py):

     class MyClassBase:
       def __init__(self):
         self.my_sequence = [1, 2, 3]

   and create a file (lib/python/Products/MyBase/__init__.py):

     from MyClassBase import MyClassBase

     def initialize(context):
       context.registerBaseClass(MyClassBase, 'MyClassBase')

   Now restart your Zope, go to the Control Panel, and Add a new product
   called "MyClass". Inside this product, create a ZClass called
   "MyClass". When creating the ZClass, select MyClassBase as a base
   class. In this ZClass, on the Methods tab, create a DTML Method
   (say, index_html) with the following source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

   Then, go to your root, drop an instance of MyClass with an id of
   "MyInstance". Now, navigate to http://your.server.com/MyInstance.
   Voila.

I probably missed two or three other ways to to it. But, I hope one of
these is what you're looking for.

Not directly from DTML.  You need to use a method on the Image object. 
manage_FTPget().

This is different from the first question that you asked.  In this case,
when your form uploads the file contents, ZPublisher will marshal that
into a StringIO object (which acts just like a python file object).  In
this case you can just do:

<dtml-var "REQUEST['name_of_form_element_that_is_the_file'].read()">

and get the 'contents' of the file.

In this case, your taking about a Zope 'Image' object, _not_ a standard
file object like you get when you upload data.  For this you need
manage_FTPget().

Has anyone noticed their dtml code mysteriously reverting to a previous
iteration of code??? Possible after a manual shutdown and restart.

In other words suppose you have a dtml document called DocA. It
contains:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Several days later you change
DocA to:

<!--#var standard_html_header-->
<h1><!--#var id--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Later that day or several days
later, after a manual shutdown and restart, DocA has reverted to:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

Ok, I guess this is where I get confused. When is the REQUEST['file']
instance
a string and when is it not? If I try to replace the manage_upload call
with
your suggestion, I get a message saying:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which indicates that REQUEST['file'] is a string at this stage (and
probably
the filename or similar). From the input form I guess "file" is a string
(at
least that is what it looks like in the input form - the filename) at
least
until I press the submit button. When it actually changes from the
filename
to a file I do not know.

Any other suggestions on how to get hold of that file?

Thanks,

Marius Kjeldahl

Your form element should be:

<input type=file name="file_name:file">

The ':file' is necessary to marshal the file into a file object.  I was
going on the assumption that you had done that otherwise as you've
discovered it will turn it into a string, which you may or may not want.

PS Don't forget the ENCTYPE="multipart/form-data" on your <form> tag.

MySQL takes a lot of criticism because it is (a) non-free, (b)
non-transactional. Non-fre I won't get into.

Non-transactional means that it doesn't support transactions. :) So what
are transactions? Say you own a bank and Joe transfers $50 from his
checking account to his savings account. The program removes $50 from
this checking account, but the disk is out of space and an error occurs
putting it into a savings account. Is Joe out $50? Not if it was a
"transaction" where all-or-none of a sequence of events happens. If at
any point an error occurs in the transaction, everything is rolled back
($50 is back in his checking account and the error is reported). MySQL's
lack of transactions rule it out IF you need transactions.

Another limitation of MySQL is that it doesn't support very large
databases. This usually isn't an issue.

Another solution is PostgreSQL, which is a free relational database
system (see http://www.postgresql.org). Postgres is very powerful and is
probably the most powerful free db by far! There are some drawbacks:
 * Last I heard, the PYTHON INTERFACE (not PG itself) for postgresql is
not threads compliant. You will have to kludge something with locks to
use it(?)... any ideas on this one, anyone?
 * You cannot remove or modify a column on your database. You can rename
the column and let it hang, or recreate the table. For changing schemes,
this can be a real pain.
 * Text beyond 16K must be stored in a large object - this is a pain.

It has some advantages:
 * Transactions
 * Super docs
 * Great reliability
 * Most of ANSI SQL Compliance
 * Stored procedures
 * Some real nice datatypes for everything from money to geometry

Alas, there is Oracle8i. It has some drawbacks:
 * Installation is a bitch! You usually have to edit kernel header
files, recompile, set mount points, apply patches, arg!!
 * Complexity; Oracle VERY complex even after you get it up and running
 * The Oracle/ZOPE interface does not have a Setup file for 8i. You'll
have to write one to compile it. (Or, email me for the one I got a hold
of)
 * Fewer column types than postgres

And the advantages:
 * Transactions, great reliability, and great SQL support
 * Java support
 * Plenty of docs. My favorite Oracle stuff is at photo.net (the web
page of some MIT guy)
 * Good interfacing with Zope, thread safe

In general, if you're willing to spend the overhead of a killer learning
curve, use Oracle8i.

Ok, I have changed my form element to what you suggested. These are the
results I am getting with various <dtml-call> tags in the VProduct_add
method (called after filling in VProduct_addForm):

* <dtml-call "REQUEST['file'].read ()">

Error Type: TypeError
Error Value: argument file was ommitted

I guess this is because no field in the form is named 'file'. So I try:

* <dtml-call "REQUEST['file_name'].read ()">

..and I get the same error. I even tried to name="file:file" in the form
element, and using REQUEST['file'].read () in the call, but then I get:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which I guess means that it now has the 'file' variable, but it is still
a string.

Any other pointers, or references to where I can read more about the
file stuff?

Thanks in advance,

Marius Kjeldahl

REQUEST['file'].read ()
                    ^
            Notice this space?

That space isn't supposed to be there.  You're supposed to be calling a
function with no arguments, the () has to be right next to the "read". 
The way you have it right now, it's looking for an attribute called read
instead of a function.

Actually you can get the image data as <dtml-var "my_image.data"> where
"my_image" is the name of your image object.

The following DTML will return the actual image to a browser (tested):

<dtml-call "REQUEST.set('Content-Type', my_image.content_type)"><dtml-var
"my_image.data">

It is crucial that the DTML method contain no extra whitespace, though, as this
will be interpreted as part of the image data.

Subject: [Zope] Zope Weekly News
Message-ID: <Pine.BSF.4.21.0003151720200.1009-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively (but I'm willing to share).


Announcements

  * The latest versions of the Zope Content Managers Guide, Z SQL
    Method User's Guide and DTML Reference Guides is available in
    postscript(ps) format.  With luck, the technical problems of the
    previous versions have been fixed.

    http://www.zope.org/Members/Pam/PSversion

  * Check out the new Zope Documentation Projects page that lists
    current Zope documentation projects and their status.

    http://www.zope.org/Documentation/Projects/Projects

  * Martijn Faassen <faassen@vet.uu.nl> has established a Zope-XML
    mailing list.  The intent is to discuss Zope's XML infrastructure.

    http://www.egroups.com/group/zope-xml/info.html


New Products

  * Software Product: iTrack Issue Tracker Product, by "shalabh"

    iTrack allows a team of people to keep track of various issues
    about a project. Currently this is in development stage (Version
    0.2.0) but usable, as long as you follow the instructions.

    http://www.zope.org/Members/shalabh/iTrack/

  * Software Product: ZGDChart Product, by "teyc"

    ZGDChart uses gdchart to draw charts.  This product comes with
    Windows binaries and source for non-Windows platforms.  This
    initial development release is 0.3.

    http://www.zope.org/Members/teyc/ZGDChart

  * Software Product: DTMLTemplate, by "halazar"

    DTML Templates are documents that allow blocks of text to be named
    and made available to other documents. The basic building block of
    templates is the DTML block tag, which can also be used with other
    DTML document types. Templates export their blocks. Another new
    tag, the suppress tag, allows block definition without rendering.

    http://www.zope.org/Members/halazar/Products/DTMLTemplate


Updates

  * Software Product: jcNTUserFolder, by Jephte CLAIN

    This product authenticates Zope users against an NT domain
    controller.  All users are encouraged to upgrade to this version,
    0.0.3.  Unfortunately, the upgrade is incompatible.  You will lose
    any role settings.

    http://www.zope.org/Members/jephte/jcNTUserFolder


Zope.org items

  * How-To: The Debugger Is Your Friend, by Michel Pelletier

    This HowTo is an invaluable resource for those days where if I get
    one more mysterious traceback, just one more and I swear I'll
    crack.  It explains how to step through Zope code line-by-line
    with the python debugger.

    http://www.zope.org/Members/michel/HowTos/TheDebuggerIsYourFriend

  * How-To: How to test your products without (re)starting Zope, by "teyc"

    This HowTo describes testing Zope products within a python
    interpreter without starting the Zope server.  This rather speeds
    up the code-test-curse-code cycle, because it allows you to
    quickly reload your Product with each change.

Subject: [Zope] Randomizing SQL Data ?
Message-ID: <B4F57760.14F5%Jatwood@bwanazulia.com>

I have some data returned by a SQL Method that I want to randomly pick from.
Since I cannot get the SQL Statement to return random data sets I was going
to use the "_.whrandom.choice" to go over the SQL list and create a new list
of the randomized choices.


This will go over the SQL Content
<dtml-in sqlMethod size=10 start=query_start>
</dtml-in>

But how do I create a list? (in Python I would just say list = () and a
list.append()

TIA,
JMA

Hi..

I just uploaded many files with load_site (thanks Itamar!), but
I ran out of disk space while doing this.
Seems as the last transaction corrupted the Database seriously.
When I try to delete the folder where the errors are I get:
Error Type: CorruptedDataError
Error Value:

The same with packing database.

And when invoking Undo, i get something like:
long int too long to convert

Any ideas what I could do to repair my database and deelete the corrupted
folders and start over again?

Thanks in advance,
    Mario

Havn't been able to so far. It seems you have to have a reasonably complete

That is a possible option. Does anyone know what the issues with this are?
From memory I think the non-thread-safeness of the odbc drivers themselves
was not the only problem. I suspect the python odbc interface might have
been not thread safe also. Can anyone confirm this?

Hi

i've spent the day trying to make this work so i thought i'd see if
brighter minds could illuminate the darkness of my night.

I'm trying to setup an email archiving system in Zope. I've got the
email retrieval setup in an separate python script and a couple of
ZClasses setup in Zope to archive/catalog the emails. My problem is
getting the parsed email info(to, from, body, etc) from the external
script into my Zclasses. i've tried xml-rpc but i keep getting server
errors. i connect to the server and try

zope.project.archive.addEmail(id)

but i keep getting a 500 Internal server error message. addEmail is just
a wrapper around the constructor which expects only one parameter the id
of the email Zclass object to create( just something to debug before i
pass in all the params). So what gives? i can call the method from the
web with

http://localhost/project/archive/addEmail?id=xx

but how do you call a dtml method with args from xml-rpc. fyi i'm using
amos's patched xmlrpclib for authentication (i fixed the import errors)

i've trying to reimplement this in an external methods but i would
really like to know how to do it with xml-rpc. btw 

Thanks

The Login Manager looks good because, unlike GUF and UserDb, it allowed
me to use the admin/supervisor password to authenticate straight away 
and so didn't lock me out of the directory.
I actually gave up on GUF because I _couldn't_ get it to let me in in
the first place to set up my db methods. The password that is supposed
to be built in didn't work at all, neither did the supervisor one.

To me this is the biggest problem with the other existing systems, that
they lock you out of your site and there is little you can do about it.
(In UserDb I had to comment out parts of the security code to get it
to let me in and set it up properly. After it was set up it worked fine
and I could put the code back.)

All authentication stuff from a database is going to require the
person to customise their own sql we can't make custom authentication
methods any easier than that, but in the simplest case this should
be _all_ they have to do. The supervisor password should _always_ work
in any authentication method from the beginning and it should be made
clear that people are going to have to authenticate using that particular
password until they have the rest of their site set up.

Anyway, the LoginManager looks very clean. It already doesn't have a
lot of the old problems and I like the abstraction. Now I just have to
finish getting DCOracle working (annoying truncated .so files...).

Yeah that was probably me, not to slam MySQL, it's fast, it's free, and
it's stable.  It's lack of transactions however means that you have to
be aware of and live with the possibilty of inconsistent states of data
between MySQL and Zope.

For read only operations, or low-write, or if an external application
handles inserting your data and Zope only reads it, this is not really a
problem.  Also, it's only really manifest if you change the database and
then change something in Zope and an error occours.  If you can isolate
your SQL calls as much as possible, then this shouldn't be a problem.

I posted a work around for that on this mailing list a couple of days ago.
And yes whilst it is frustrating it is no where near as hard as writing 
an authentication product from scratch (which from experience is difficult).

Last time I used it came with a very simple example already. All you need
to do is add in your logic and you're away. The SQL Howto on the website is
very informative (cheers to whoever wrote that).

Sorry I think that the GUF is also very clean and quite easy to work with.

I think GUF is great as it is. Thanks a lot to Zen for contributing it.

I would have to recommend postgresql. I've got a prototype ecommerce site 
running with Zope at the front, some python in the middle and postgresql
at the backend. Currently it is a prototype so we only have about 20,000
items in there at the moment however it seems to work very well. (Once I 
brushed up on some of my SQL).

Check it out at http://www.postgresql.org

I see a couple of issues with this:

1)  This may not scale well; if select_data becomes large you may
be spending a while in the dtml-in loop.

2)  There could still be a race condition here, between the check for
data and the insertion (especially coupled with the above point - the
probability would increase proportionally with the load of the machine
and the size of the table). I say "could" here (guardedly :-), because
I don't know how Zope's transaction semantics are implemented, and how
they affect the DA that you're using (does anyone have any pointers to
documents?  I've just started reading "How to Write a DA", and this
mentions the distributed commit protocol).

I'm not sure if a solution to the original problem is to surround
the insert with a <dtml-try> tag;  I'm going to try this myself
sometime today (if I get some spare time :-).

Subject: [Zope] XML-RPC Woes
Message-ID: <38D0221B.794D6C3A@wm.edu>

Hi

i've spent the day trying to make this work so i thought i'd see if
brighter minds could illuminate the darkness of my night.

I'm trying to setup an email archiving system in Zope. I've got the
email retrieval setup in an separate python script and a couple of
ZClasses setup in Zope to archive/catalog the emails. My problem is
getting the parsed email info(to, from, body, etc) from the external
script into my Zclasses. i've tried xml-rpc but i keep getting server
errors. i connect to the server and try

zope.project.archive.addEmail(id)

but i keep getting a 500 Internal server error message. addEmail is just
a wrapper around the constructor which expects only one parameter the id
of the email Zclass object to create( just something to debug before i
pass in all the params). So what gives? i can call the method from the
web with

http://localhost/project/archive/addEmail?id=xx

but how do you call a dtml method with args from xml-rpc. fyi i'm using
amos's patched xmlrpclib for authentication (i fixed the import errors)

i've trying to reimplement this as a xmlrpc call to an external method
but i would really like to know how to do it with xml-rpc and dtml. 

Thanks

Kapil

My experience with SyBase is that the adapter development is
kind of slow, and only Linux platform is supported. And
currently it has some glitches with some data types (decimal
with 10 or more digits), it does not support stored procedures,
and the implementation in Zope 2.1.4 crashes when you have
date fields ending between 59 and 60 seconds (e.g: 59.23 sec).
Also, when there is database problem, the adapter very often
just hangs and lock the database out, requiring a Zope reboot.

So, SyBase in Zope is not really in great shape. I don't know
about other databases, maybe other database adapters have
problems, too. SyBase adapter is workable for me (after I
patched the problem areas), just not that great in its current
shape. It has transaction, though, which you definitely want.
The thing is, SyBase itself seems fairly solid, it's just the
Zope adapter that is still not perfect.

regards,

Hung Jung

Subject: [Zope] DateTime exceptions
Message-ID: <00031611243805.02516@localhost.localdomain>

Greetings,

A workmate of mine has had this problem also, and now it's happened to me.

I cannot catch exceptions from the DateTime object!

My code:

<dtml-try>
    <dtml-call "REQUEST.set('delDate','%s/%s/%s' % (delYear, delMon, delDay) )">
<dtml-except>
    <dtml-call "REQUEST.set('delDate',0)">
    <font bgcolor="red">You have entered an invalid date.</font>
    <dtml-call "REQUEST.set('Error',1)">
</dtml-try>

Now, from my understanding, this should catch ALL exceptions.  So why, when i
give invalid values (like -1) does ZOPE give me an error page?

Is this some deficiency in the way the DateTime object handles exceptions?  Or
is there some funamental zen i'm not groking?

Have a better one,
	Curtis.

I would write the select_data query to only select a single record, i.e. the one
I'm worried about duplicating.

Heh. I certainly wouldn't want to do it from scratch myself...
I just tracked down your work around again and now remember why it didn't
help me. I actually have a UserDb in my root directory and that's what I'm
trying to get rid of (Since I'm moving to Oracle anyway I thought I'd
change to a supported product since UserDb has been giving me a few obscure
problems at times.) So since it doesn't support the admin user either your
suggestion doesn't help. I will, however, try making a normal user folder
in a subdirectory and then try to set GUF up in a subdirectory of that...

Grin. Seeing I never managed to get into GUF's management interface in the
first place I can't really comment on how clean it is.

IIRC, all you need is the libraires, a seperate download. I have a
couple machines that only have the libraries, and work just fine. Of
course, they are on various unixen, YYMV on NT.

Hi there,

Firstly, I'm not a member of this mailing list, although I have an archive
of over 2000 messages from it.  Could anyone replying to my message please
reply to tim_haines@hotmail.com as well as the list?  Thanks.


I've been developing a site using nt4, Access, and the odbc plugin.  Things
work great - most of the time.

I've noticed that occaisionally I get any error message that mentions
tpc_begin.  When I do a refresh, the problem is gone, and the site works
fine again.  I've also noticed that this normally occurs the first time a
database query is executed after a reboot.

Does anyone know why this would happen, or have any insights at all?  I look
forward to hearing from you.

Tim.

One thing I should point out firstly is that the LoginManager inside
the PTK isn't finished yet and the developers don't suggest actually
using it just yet.

While I said it looks great (and it does) and it accepts the admin
password it does _not_ yet have the api in place to let you authenticate
from SQL. So you probably want to wait a bit still.

But after saying that if you still want to look at how they are going
you need to actually install the Portal Tool Kit first.
Have a look at it's install instructions at:

Can you provide more specific detials? I am running two seperate systems
with Sybase, one of which is pounded on pretty hard, with zero problems.

Hello.

Many thanks to all for your answers on my recent question about MIMETools.
Really, tag <!--#boundary --> is implemented now, and works, but...
I need sending mail with multiple file attachement...
Combination of several tags <!--#boundary --> working...
When I tryed insert tag <!--#boundary --> into tag <!--#in -->,
Zope said: "Unexpected tag, for tag <!--#boundary ..."
Because <!--#boundary --> is only meaningful in the context of the 
<!--#mime --> tag.
We have loss of this context? Below example of my stupid code.

[ --- begin code snippet ---]

<!--#mime type=text/plain encode=7bit -->
just example text...

<!-- #in "files_to_mail" -->
<!--#boundary type=application/octet-stream disposition=attachment 
encode=base64-->
<!--#var sequence-item -->
<!-- #/in -->

<!--#/mime -->

[ --- end code snippet ---]

Any ideas?

Dima.

Are you just afeter a single random item from a ZSQL query? 
If so:

<dtml-with "_.whrandom.choice(_['getcategories'])">
	<dtml-var category>
</dtml-with>

Works for me. In this case, 'getcategories' is a ZSQL method that
returns a list of categories, consisting of:
"select category from linkCategories"

Message-ID: <38D077D6.CC74ABB3@suprize.com>

Hi,

    Zope seems to evaluate expressions in an unconventional way.
Say I have three properties, a=3, b=5, c=7 set in a Folder. In
a DTML Document I tried to say <dtml-var "a/b*c"> and got result
0. The expression was evaluated as a/(b*c) and rounded off. Is
not the expression supposed to be evaluated as (a/b)*3? The
result is not correct still if we put it this way:
<dtml-var "(a/b)*3">. I still got 0 as the result. Did I miss
anything fundamentally or is this a, bug?

Hi Zopistas,

I now that the failure is because the object in the namespace is "PARENTS". So what is the name of the root folder?

Hi,

    Suppose the following folder/Obj structure:

		Zope Root
		    - test
                        showImage     (DTML Document)
		        - image
			    testImage (image object)
		    - test2
                        testProgram   (DTML Document)

    showImage contains one line of code:
       <A HREF="test"><dtml-var "image.testImage"></A> 
    that shows the testImage properly alone. But if I put
    <dtml-var "test.showImage"> in testProgram (in test2),
    I got all "<" as "&lt;" and the ugly code like the
    following was returned intead of the image with link.

&lt;A HREF=&quot;test.html&quot;&gt;&lt;dtml-var
&quot;testImg&quot;&gt;&lt;/A&gt;

    I have tried the following but none works out:
	- Use DTML Method instead of DTML Document to hold
	  showImage
	- Use "/" instead of "." to point to objects
	- Use single quote or no quote instead of double quotes

    Please advise the proper way to resolve this annoying issue.
    Thanks a lot!

Most of the unfinshed pieces have to do with giving users
propertysheets. That makes it not quite useful for PTK yet.

I'd say for non-PTK use it's in pretty good shape.  Would I recommend
using it currently? Well, for a production sight, I think maybe it's a
bit too new.  It could stand more testing and security review.  But, if
you're developing a site that you don't need to go live tomorrow, I
say sure, go for it. It's quite useable for non-PTK applications.

Sure it does! Got a SQL-based GUF? You should be able to take your GUF
userExists/userRoles/userAuthenticate/etc methods and plop them
unchanged into a LoginManager Generic User Source (GUS), and have it
Just Work. 

You're probably thinking of the comment that it's not ready to do
SQL-based PTKs. This is because the propertysheet support that PTK needs
isn't there for SQL. But, that's a feature that no other SQL-based
userfolder has anyway -- it's a new thing, and at the moment only PTK
needs it.

Sadly, the way DTML tags work right now, this isn't possible.  Since
'boundary' is part of the 'mime' tag, like 'else' is part of 'if', you can't
put it inside another tag.  The only workaround I can think of is pretty
nasty; look at the source for MIMETag and use the MimeWriter class directly.
It's not that bad, unless you don't know Python...

Urk.  First, we can pick this apart in at least two ways:

<dtml-with "PARENTS[-1]">

or

<dtml-let rootObject="PARENTS[-1]">

In either case, the part in quotes takes the last element of PARENTS, giving
you the root folder.  In the first case, we use this directly in a
"dtml-with", and can refer to properties and contents of the root folder
inside it.  In the second case, we give the root folder the local name
'rootObject' which we can then use to access it.

Evan @ digicool & 4-am

You've run into a misfeature of Python.  Since 'a' and 'b' are integers,
'a/b' is performed as an integer division.

Thus 'a/b*c' == '(3/5)*7' == '(0)*7' == '0'.  If you want floating point
division, you need to make 'a' or 'b' a float, either directly or by writing
'_.float(a)/b*c'.

Subject: [Zope] Version bug?
Message-ID: <38D10EEF.156ABF9E@globalcrossing.com>

Greetings!

I think I may have found a bug in the way Zope handles versions.
To recreate:

1) Set up a version, say, "TestVersion."
2) Rename the version to something else, say, "NewTestVersion."
3) This breaks the following:
   * When you enter the version, the "you are working in" line displays
     "TestVersion"
   * The "Version Management" Control Panel link shows TestVersion as
     well (this breaks the link, too)
   * Any file modified by the version shows up as TestVersion, too.

This happens on:
  Zope version: Zope 2.1.4 (binary release, python 1.5.2, linux2-x86)

Is this a bug?

Hi Zopistas,
	Thank you for the answers. My problem arose because I was passing a DTML Method a list of strings: [ 'PARENTS[-1]', 'FolderA', ...]. And while I could do:
	<dtml-with "_( folderObject=_.getitem('FolderA'))">
I could not do the same with 'PARENTS[-1]'. The simple solution suggested by your answers is to just pass the objects themselves (duh!): [ PARENTS[-1], FolderA, ...].
	But out of curiosity I'm still wondering if there is a way to refer to the root folder by name so one could write
	_.getitem( 'rootFolderName' )

Subject: [Zope] How do I set properties from DTML? (Repost)
Message-ID: <00031617290300.13146@promotor>

I'm reposting due to mail problems ...

I'm working on a thing I'll probably call "ZBox"; it's a "widget
method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Sure, you just need to trace my previous postings. :)

SyBase adapter has two specific problems that I have ran
into. They are both 100% reproduceable and both have been
reported to the Collector. One of them is now fixed for
Zope 2.1.5 (the _validTime thing.) The other one still sits
still waiting for Digicool to fix it. If I say the development
of the adapter has been slow, it's because it's been slow. If
I alone have been able to find (and fix) two problems
and one limitation, somehow I don't think they are the
only problems and limitation. :)

Some of the bugs are later found independently by other
people, too. (See below.)

Many people also say that they have zero problems with
Microsoft Windows. I guess they just have been lucky. Ha ha.
But just because one person is lucky, it doesn't mean the
rest of the world is equally lucky. :) Let me teach you
how to para-phrase your question:

"Can you provide more specific details? I am running two
separate system with Sybase, and I would like to know more
about these problems."

Very nice. The following are three articles in chronological order.

Subject: [Zope] XML-RPC Woes
References: <38D0221B.794D6C3A@wm.edu>
Message-ID: <38D129D3.B15C9835@wm.edu>

After getting a few private emails with questions about what i was doing
i thought i'd share what i'd learned and some code.

First an apology, i read through my original email and realized that i
was a bit to vague to really get any help, mainly because i don't
understand what i'm passing through xml-rpc to dtml methods that are
expecting Zope stuff (client, mapping, kw).

Second, what i'm doing. I'm creating an email archive in zope. i wrote
up some python code that retrieves/parses email from a pop3 server and
then inserts via xml-rpc into a zclass so that it can be archived and
cataloged. I got the whole thing working last night by passing the
parsed info in a dict via xml-rpc to an external method which
took care of adding the Zclasses in Zope, basically following the
example from this howto http://www.zope.org/Members/teyc/howxmlrpc

Third, How to do XML-RPC with Amos's patched xmlrpclib.py for
Authentication:
    1. Assuming you already have the original xmlrpc implementation from
pythonware.com installed, copy Amos's xmlrpclib.py over it (WARNING this
will basically delete the original).

    2. Fix the subclassing error. Find 
	class BasicAuthTransport(xmlrpclib.Transport):
	and change it to
 	class BasicAuthTransport(Transport):

    3. Fix the import error. after the comments there are some imports
add:
	from base64 import encodestring



<dtml-with Standard_Code_Disclaimer>
all code is provided on as is basis for the purpose of an example. use
at your own risk.

Fourth. External Method Code:

	def import_mail(self, props):
		id = props['id']
	mailobj=
#netscape mangles this line
self.manage_addProduct['YourProduct'].YourZClass.createInObjectManager(id,
self.REQUEST)

	mailobj.propertysheets.YourPropertySheet.manage_changeProperties(props)
	return "Zope is Cool"


this is one of those times you just look at zope and sigh. so much power
if you know how to use it. i actually got the basis of this code from
the Zope CD that they passed out at the python conference(8). this
method is part of the archive folder called below.

Fifth. The XML-RPC call: from the python script without error checking

        self.zope = xmlrpclib.Server(YourZopeServer,
                            xmlrpclib.BasicAuthTransport(userid, passwd)

        Props = {
            'Id':Whrandom.Randint(0,1000000),
            'To':Prop_list[0],
            'From':Prop_list[1],
            'Subject':Prop_list[2],
            'Date':Prop_list[3],
            'Body':Prop_list[4]
            }
        Print Self.Zope.Test_project.Archive.import_mail(Props) 


</dtml-with>


I hope this helps. if anyone has any examples of passing args to dtml
methods via xml-rpc i'd love to see them. 

Cheers,

Kapil

No, its integer :)
3/5 is 0, anything multiplicated with 0 will be 0.
so 3/5*7 is 0 no matter where you set brackets :)
Integer does not round, it only cuts off everything after the "."

Eventually you want: a=3.0, b=5.0 and c=7.0
(even only one variable beeing "float" wuld be sufficient)

<dtml-let d="{}">

do something with the resulting dictionary...

so far so good. But how to I add items to the dictionary? 

<dtml-call "d[key]=value">  gives me syntax error.


Thank you!

Okay, I *think* I am beginning to grok zclasses, but I have a couple
of questions:

What is the scope/namespace of a ZClass' methods?  In my tests, I
cannot access other methods of the same ZClass.  I *can* access
methods in parent folders of my ZClass, but not the current folder.
Ie: Create ZClass called zcTest.  Create two methods in this ZClass,
called index_html and test.  Neither can see the other.

Secondly, when I try to access anything off of instances of my zclass
except for property sheets, I get access denied.  Where do I set up
the permissions to allow my methods to be viewable?

Subject: [Zope] ZODB question, again
Message-ID: <38D13016.6F9160EC@sage.att.com>

ok, persistent fool that i am, i'm still trying to figure out
how to use ZODB in an External Method to do some simple (ha!)
database stuff.

so i built a very simple app, to implement a counter.
each time you invoke the "Count" method, you get a number
back, and it increments.

running the script (see below) by hand, it works fine.
referencing it from Zope, using this dtml fragment:

	<dtml-var "Count( 'chickens' )">

or just pointing my browser at:
http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=chickens

to reference an External Method called Count, which 
refers to the Count function in this script, i get:

   Error Type: AttributeError
   Error Value: Counter

if i then click the reload button, i get:

   Could not lock the database file. There must be another
   process that has opened the file. 

and i'm locked out until i restart zope.
can someone please help?  this is getting really
discouraging.  a simple explanation of where i'm 
going wrong would be greatly appreciated.  a small
working example of a working app would be terrific.

thanks


--------------------------------------------------------------
script follows:

import ZODB, ZODB.FileStorage
import Persistence

class Counter(Persistence.Persistent):
	"""A Persistent Counter"""
	def __init__( self, name ):
		self.name = name
		self.value = 0

def Count( name ):
	"Get counter value, then increment, creating if necessary"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/CountDB.fs' ) )
	connection = db.open()
	root = connection.root()

	if not root.has_key( name ):
		counter = Counter( name )
		root[ name ] = counter
	else:	counter = root[ name ]

	counter.value = counter.value + 1
	
	get_transaction().commit()
	connection.close()
	return counter.value

I'm able to get Zope to dump a core file if run in debug mode ('-D').  I
haven't proved this, but I suspect that when a fork()ed child dies it
does not dump a core file.  Since debug mode does not cause Zope to fork
off Zope as a child from the parent watchdog, a core file is produced. 
None of this is mentioned on the fork() man page, or the clone() man
page, or whatever.  I probably need a good UNIX programming reference to
verify it.

Give it a try, fire up Zope in debug mode and run your load scripts
against it to reproduce your segfault.

Message-ID: <4.2.2.20000316001051.00a9f710@postoffice.pacbell.net>

I am having trouble with userDB cookie authentication in IE 5 through the 
@Home network. Apparently @Home uses a proxy server for all of their 
traffic. When accessing the docLogin page for authentication the user 
receives a "Cannot Display This Page" error from IE 5. Turning off 
cookie-based authentication seems to solve the problem. This problem does 
not occur in Netscape under the same conditions and does not occur in IE 5 
when used outside of the @Home proxy.  Does anyone know of specific 
problems with IE 5 and proxy servers? Is there any solution outside of 
using standard authentication?

Chien

Try this

<dtml-var "_.float(a)/_.float(b)*_.float(c)">

You calculation is using integers and there is no automatic conversion being
done.

You need to explicitly tell zope that you want float calculations.

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:


ERROR(200) ZServer uncaptured python exception, closing channel
<zhttp_server listening :8080 at 81f5b90>
(exceptions.TypeError:unpack non-sequence

[/usr/local/zope/2-1-4s/ZServer/medusa/http_server.py|handle_accept|609])

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

You cannot open the object database twice.  In this case, Zope opens it
first, and then you open it second (why you are getting the
AttributeError I don't know, a traceback there would help).

Basically what you are doing is sort-of a no-no unless you know what you
are doing.  First, a database cannot be opened twice, even from the same
process.  Second, you do not need to open the database again, because it
is already open and accessible to you from your external method:

def anExtMeth(self):
  connection = self._p_jar

All persistent objects (in this case, 'self' being the container of the
external method, probably a Folder) have an _p_jar attribute which is
their connection to the database.  Always use that instead of opening
your own.

Also, you need to be very careful with what you are doing.  You are
inserting objects right into the root level of the object database, this
is not really a good idea.  For example, let's say you fix your code to
not open the database again and you get it working.  Then (don't!) try
this URL:

http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=Application

Doh!  Guess what?  You just trampled your entire Zope, hosed the entire
enchilada, because Zope also lives in that top level namespace, and its
name is 'Application'.

Pick your own name (like GarryHodgsonApplication) and assign your
counter objects as sub-attributes of that.

Subject: [Zope] Zope Cookie Handling
Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF373@ap3expr3applge.appl.ge.com>

All,

Here is another interesting issue that I have encountered while trying to
process cookies in Zope.

On a different app. server I have a Java class which generates an encrypted
cookie when a user logs into the site.  When the user navigates over to my
Zope site, I wish to check the value of the UID.  I do this by retrieving
the cookie within the following snippet of DTML:

<dtml-if "REQUEST.cookies.has_key('UID')">
		<dtml-call "REQUEST.set('cookie',
REQUEST.cookies.values())">
		<dtml-var "validateCookie(REQUEST, REQUEST['REMOTE_ADDR'])">
</dtml-if>	

This DTML calls a DTML method (validateCookie) which in turn is calling the
following External Python Method:

import xmlrpclib, base64

def validateUID(self, REQUEST, ipaddr):
        cookie = REQUEST.get('cookie')
        servlet =
xmlrpclib.Server("http://salesnet-dev.appl.ge.com/geaservlet/X
mlRpcTest")
        cookie = repr(cookie)
        cookie = cookie[2:]
        cookie = cookie[:-2]
        return servlet.validateCookie.check(cookie, ipaddr) 

This XML-RPC call attempts to invoke the Java decrypt method.  Herein lies
the problem:

Upon investigation of the value contained in the UID cookie, Zope returned
the following:
\316\313\321\310\316\315\314\311\321\312\316\317\317\223\310\321\315\317\313
\316\317'

If I print out each character created during the Java encrypt method, the
following values are returned:

\206\203\209\200\etc.etc.

A colleague of mine pointed out that Zope was returning the values in Octal
rather than decimal.

Is this behavior by design?  Is there another mechanism I can use to
retrieve the raw cookie value before Zope places it in a dictionary?  Rather
than code a string parsing routine in Java, are there any suggestions as to
how to convert each character back to decimal, or obtain the string prior to
being converted into octal?

Once again, I appreciate the assistance/responses.  Everyone on this group
has been wonderful to interact with.

-Brian

This apears to be fixed in the CVS.  The reason is dispatcher.accept may
return None if the accept() sys call returns EWOULDBLOCK.

Assignment cannot be done in DTML, it is a security risk.  DTML was not
designed to be a general purpose programming language; it's meant to be
a reporting language.  Use python (either external methods or
PythonMethods) if you want to do this.

Subject: [Zope] Problem with ZODBCDA
Message-ID: <38B478360010B51B@smtp.visto.com> (added by administrator@visto.com)

I just installed ZODBCDA on a new Windows install of Zope 2.1.4 using ZServer running as an NT service.  After editing db.py to fix the THUNK typo (I've submitted that to the collector) it sees the System ODBC DSNs that exist, and it lets me pick one.  But when I try to open the connection, it tells me I have an invalid connect string.  The weird thing is that I turned on Windows ODBC tracing, and NOTHING is being logged from the Zope connection.  So I don't think it is actually passing anything to ODBC.  If I do the same thing from some other ODBC client, the connect string works and the session gets logged by the ODBS tracer.

There was a very similar problem in the list archives several months ago, and it seemed that running the service as a user, instead of the system, fixed the problem.  Didn't work for me.

Any suggestions on how to track this down further, or better yet to fix it, would be appreciated.

Subject: [Zope] ZODBCDA problem partially solved
Message-ID: <38B478360010BA29@smtp.visto.com> (added by administrator@visto.com)

Within the last half-hour I posted that ZODBCDA connections were not working correctly on my machine, with Zope running as an NT service.

I rebooted the computer and now the connection gets made. (I hadn't rebooted since I changed the user the service was supposed to be running as.)  So with the Zope service running as me, rather than as the system, it seems fine.
And now my problem is exactly the same as the one in the archives last year.  This doesn't seem too serious, but if anyone knows why it cares who Zope is running as, I'd still like to know.

Thanks,

Matt

Fortunately MySQL has transactions high up on the todo list (but it's

Zope doesn't do anything above and beyond what python does.

Python rounds integers, quite simply:

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> 1/2
0
>>> 3/5*7
0
>>> (3/5)*7
0
>>> 3/(5*7)
0
>>> 

integers as input gives an integer as output.  Obviously there are two
schools of thought on this.  If you want a floating point number, use
'float()' (or in DTML, _.float())

>>> float(1)/float(2)
0.5
>>>

<dtml-var rootProperty>

Sorry, this is not right. 

<A HREF="test"><dtml-var "image.testImage"></A>

is right. Next time I will test it ... :(

Uups, sorry

<dtml-var "test.showImage(_.None, _)">
           ^^^^^^^^^^^^^^ 

but i think you have to call also

I tried to use MySQLDA without success.
I have a redhat 6.1 and MySQL 3.22.29 installed. I even installed a
unixODBC connection to MySQL that works.
How can I access this database through ZOPE.

When I try to make the MySQLDA extension a lot of errors come out of it
:

Can you help me ?


Does DigitalCreation have a solution on connecting to MySQL on a Linux
Platform (thanks to ODBC or something else).

Thanks in advance.

You have to convert it from integer to float. Try:

<dtml-var "(_.float(a)/b)*c"> 

Though you're rigth, you need the parenthesis for the correct
evaluation.

Hello there

I' ve got some difficulties with the very final step of ZOPE-Installation:
I made the start-script as root (-> python wo_pcgi.py) and got all the neccessary scripts. Then I chown and chgrp all files to my ZOPE-user and tried to start up the server. Unfortunately the script has got some endless-loop or so and I have to break (Ctrl-C) in order to get my prompt and logout. I do have access to the server via WWW but only until I break the script. 

Do you know some hint?
Thank you very much!

The root folder can indeed be accessed by PARENTS[-1].

<dtml-with "PARENTS[-1]">

is all you need.

Keep in mind also that if the property of the root folder you're trying to
get at has a unique name, you can get to it via acquisition. (If the
property is called "foo", <dtml-var foo> would look up the property and find
it, all the way at the root.)

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

Your properties look like integers, and I believe that is your problem. Try
this:

<dtml-var "_.float(a)/b*c">

By converting a to a float and then doing the rest of the expression, python
should consider the whole expression to be floating point.

Subject: [Zope] BIG ZODB - Scalability
Message-ID: <E12Vac2-0001CF-00@home.delysid.org>

Hi.

I just got the job to find out how we (the technical university Graz)
could build up a large image-database for different users..
Zope came to my mind because of its oject oriented structure.
And because I'd really like to do Zope work at work :).

I now have to find out how Zope can be used with really large
databases.
(100000 to 1mio objects theoretically in the future).

Can anyone provide me with URLs or information on:
The relational Database Storage Manager (couldnt find any references)
  (is this intented for large databases?)
Or splitting the Zope hirarchy into multiple ZODB FileStorage Manager
instances. SO that I could e.g. save on subfolder of the root folder
in on data.fs and the next subfolder in another data.fs

I am thinking of the filesize limit of some operating systems.
2GB isnt really much.

I think that a FileStorage would be better for our content (images),
because performance issues (never saved 20GB in an relational database before :) )

Any help is appreciated,

There are three errors here :-)

First, Python atribution doesn't return the value like C. The
value of "myObject = 1" is None.

Second, as you said, 'PARENTS[-1]' is not an object. Using
_.getitem Zope will look for an object with this name, which
doesn't exist.

Third, there is absolutely no reason for the _.getitem.

What you want can be acomplished with:

<dtml-with "PARENTS[-1]">
   ...
</dtml-with>

or

<dtml-let rootObject="PARENTS[-1]">
   ...
</dtml-let>

depending on what it is you want. :-)


Also note that if you're using SiteAccess' virtual hosting,
PARENTS[-1] will (IIRC) not give you the root folder, but the
virtual root.

testProgram should *call* the showImage method, otherwise you just insert a

Thanks, I've never accessed the CVS. How soon might the fix show up in a
release? (Or is there a simple change I can make to one of the .py files
until that happens?)

I would implement this whole thing as a Python product and avoid mucking around
directly with the persistence machinery altogether. This would allow you to add
a Counter object anywhere in the Zope tree.

import OFS, Persistence

class Counter(OFS.SimpleItem.Item, Persistence.Persistent):

    def __init__(self, id, title):
        self.id = id
        self.title = title
        self.counters = {}

    def Count(self, name):
        if not self.counters.has_key(name):
            self.counters[name] = 0
        v = self.counters[name] + 1
        self.counters[name] = v
        return v

manage_addCounterForm=HTMLFile('methodAdd', globals())

def manage_addCounter(self, id, title, REQUEST=None):
    ob = Counter(id, title)
    self._setObject(id, ob)
    return self.manage_main(self, REQUEST)


Add a Counter call 'counter' to a folder, then call:

<dtml-var "counter.Count('chickens')">

Subject: [Zope] New LocalFS Release
Message-ID: <03f001bf8f8f$4dcdee20$eb0217ac@dev.prognet.com>

Version 0.1.6 of LocalFS is out. I'm calling this one the Ides of March
release. :)

New in v0.1.6:

 - Fixed a bug with filtering in directory browse view.

 - Fixed bogus text/html content-type on non-HTML files.

 - Use a more aggressive search to determine whether files are 
   binary or text. This causes directory browsing to take a bit 
   longer but hopefully prevents file corruption problems.

 - Added a Properties tab which allows specifying custom properties.

 - Improved the formatting of directory browse view again with tables.

 - Convert .xml files to XMLDocument objects if the XMLDocument 
   product is installed.

 - Convert .stx files to StructuredDocument objects if the 
   StructuredDocument product is installed.


In 0.1.7 I'm adding fully-customizable mapping of file extensions to
content-types, Zope object classes, and icons in the directory browse view.
Hopefully that should be out pretty soon as well.

  <dtml-call "REQUEST.set('minorVer',ua[iMSIE4+8])">
  <dtml-if bMSIE4>
   <dtml-if "minorVer == 'p' or minorVer == 'b'">
    <dtml-call "REQUEST.set('bMSIE4_beta',1)">
   </dtml-if>
   <dtml-if "minorVer == '1'">
    <dtml-call "REQUEST.set('bMSIE4_01',1)">
   </dtml-if>
  </dtml-if>
 </dtml-if>
 <dtml-if "_.string.find(ua,'MSIE 5') != -1">
  <dtml-call "REQUEST.set('bMSIE5',1)">
 </dtml-if>
<dtml-else>
 <dtml-comment>
  Let's assume netscape
 </dtml-comment>
 <dtml-call "REQUEST.set('bNetscape',1)">
 <dtml-if "ua[8] >= '4'">
  <dtml-call "REQUEST.set('bNetscape_4',1)">
 <dtml-elif "ua[8] >= '3'">
  <dtml-call "REQUEST.set('bNetscape_3',1)">
 <dtml-else>
  <dtml-call "REQUEST.set('bNetscape_2',1)">
 </dtml-if>
</dtml-if>


Include this in your standard_html_header and then use the variables in your
pages as normal,so:

<dtml-if bNetscape_4>
  do netscape specific stuff
<dtml-elif bMSIE4_01>
  do IE specific stuff
</dtml-if>

Hello Olivier,

Thank you for your help. The call to the method seems ok, but the code
of the method is displayed instead of been executed. May be is it a
code for external method ? Other things to do instead copying the code
to the DTML method code window in the Zope interface ?

Anyway, could someone please post an exemple of an DTML method
accepting parameters - that is the code to put in the proper windows
in the Zope interface - or a pointer to a document explaining how to
proceed ?

Thanks in advance,
Greetings,
Eric

I don't know.  Further, I'm not sure if the fix is in the 2.1 branch. 
Possibly not, so you'll have to wait until 2.2 which has no release data
set and will probably go through a thorough beta period.

Not really.  Check out the zope site under Resources and read the
instructions on how to check out code from the CVS.  You could probably
get away with replacing your ZServer/medusa directory with the CVS
version, but don't be suprised if that doesn't work.  In fact, if you
aren't confident about that or don't know how to use cvs or don't know
python, I don't recommend you do that at all.

Subject: [Zope] Subclassing ZObjectManager in ZClasses
Message-ID: <4.2.0.58.20000316233055.0163ae70@192.168.0.2>

[Repost - previous message was truncated.]


Hello,


I've been playing with ZClasses and I ran into an issue with ZObjectManager.

Summary: (when creating a folderish ZClass and cascading base classes) if 
ZObjectManager isn't subclassed at 1st level, objects can be added to the 
folderish ZClass instances but they don't show in the manage_main object list.

[Zope 2.1.4 on Win32, pure ZClasses, no Python around]

More details:

1) I first tried this simple setup. It worked fine:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyTestClass

MyTestClass is folderish and works as expected.


2) This setup worked fine too:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyBaseClass
     |_MyTestClass1
     |_MyTestClass2

I can create a custom base class and use it in several ZClasses. They are 
folderish and work as expected.


3) Then I tried this setup:

ZClass_for_CatalogAware
ZClass_for_Renderable
   |
   |_MyBaseClass
   |_ZObjectManager
      |_MyTestClass

Here I first created MyBaseClass, then I subclassed it together with 
ZObjectManager when creating MyTestClass.

MyTestClass looked OK; I created a Content view linked to manage_main; I 
allowed adding standard object types such as Folder and File.

However, when I add objects in an instance of MyTestClass they do not show 
in the object list (Content view). I *think* they are actually added 
because I cannot add an additional one with the same ID: I get an "ID 
already in use" error.

When testing further I got the same results when CatalogAware and 
Renderable were not around. Same results too when subclassing Folder instead.

It's not that bad, but I can't create a standard base class, then use it to 
create a folderish variant.

Does anyone understand why?

Your pattern is ^/Zope/(.*).  The ^ means match the beginning of the
'script path'.  So, this pattern will match:

http://www.test.net/Zope/

Keep in mind this will NOT match http://www.test.net/Zope (without a
terminating /).  If you want to match:

http://www.test.net/

The use the pattern ^/(.*)

You many need to play with the initial /s a bit.  Various versions of
mod_rewrite have done this different ways, some versions match ^ up to
the first /, and some don't.

Do note the rewrite documentation at 
http://www.apache.org/docs/mod/mod_rewrite.html

configurability and flexibility of Sendmail. The downside to mod_rewrite

Message-ID: <20000317004314.A1830@owl.rhein-zeitung.de>

Hi,

I am currently developing a new product for my company using Zope. No I am
running into a problem. I like to use the building user management and user
auth features, but I also need add to some new properties to a user record.
Nothing big just a few properties, that a relevant for some user specific
configuration parameters.

Can I add new properties to an User object, or do I have to create a new
UserFolder and new User object using ZClasses? The later wouldn't be very
satisfying. Or can I just create my own type of user and add it to any user
folder? Especially the buildin user folder of Zope?

Bye, Oliver Andrich

If you're using the 'start' script, background it:

Has anyone else seen this type of message.  We've been assuming they are

The Z SQL Methods User's Guide

This shows you everything you need to know to do things the Zope way. It assumes
you have a basic understanding of HTML forms and the SQL language.

I have gone a little bit down the road toward a design for this:

  http://www.zope.org/Members/tseaver/CosNaming

I also have some hackish code on my local box which exercises a tiny portion of
the design.  The code is too ugly to release, but I do hope to be working on it
over the next few weeks.  There are a couple of other folks on the list
interested in CORBA as well -- I'll CC them in case they have gotten further off
the dime than I have, and would therefore be able to bump your comfort factor up
a bit higher.  Perhaps we should set up another list for this topic?

There is a special piece of syntactic sugar for one-based numbering::

  <dtml-in "_.range(x)">
    <option><dtml-var sequence-number></option><br>
  </dtml-in>

(See $ZOPE_HOME/lib/python/DocumentTemplate/DT_InSV.py for more grubby details).

Subject: [Zope] External Methods and REQUEST
Message-ID: <38D1A522.E70421A6@picknowl.com.au>

Greetings,

I've started having a serious fiddle with External Methods, and have
run across a couple of brain issues:

1)  Most examples I've seen (well, both :-) pass REQUEST as a parameter
in addition to self (for example, def frobnicate(self, REQUEST)).  Yet
I've noticed that I can pull REQUEST out of self's namespace, and they
appear identical.  Is there a reason for passing in REQUEST explicitly?

2)  (And if this is related to point #1, then you may beat me around the
head with a Nerf bat).  I defined an external method called frobnicate
as follows:

def frobnicate(self):
    "One of many test functions"
    return self.REQUEST.form

and install it.  If I call it with http://localhost/zope/frobnicate?foo=bar
it returns a dictionary of {'foo' : 'bar'}, as it should.  If I call
it without any arguments as http://localhost/zope/frobnicate the
browser hangs and eventually times out with "The document contained no
data".  I'm specifically interested in form data here, which is why I
haven't used the REQUEST['thingo'] idiom, so I suspect I must be
accessing REQUEST incorrectly.  Any clues would be most welcome (if
only someone could write a ZenOfZope product; I'd download it into my
brain in an instant! :-)

--=====_95326528641=_
Content-Type: text/plain; charset="ISO-8859-1"

Overview

I am trying to put an XML structure into a Zope product that mirrors the=
 hierarchy.

The dtd for the XML is roughly of the form
<!ELEMENT nodes (node)*>
<!ELEMENT node (node|leaf)*>
<!ELEMENT leaf (object)*>
<!ELEMENT object EMPTY> 

The 4 elements share several attributes and each has some unique=
 attributes. So the intent is to group the common attributes in a couple of=
 property pages and create an property page for each individual element.

The desired ZClass representation is as follows:
container (object manager)
    base () {to contain common property pages}
    nodes (object manager, base)
        node (object manager, base)
            leaf (object manager, base)
                 object()

I build the hierarchy, set permissions as follows and do the factory edit=
 button trick
container - add_nodes
nodes - add_node
node - add_node, add_twigs
twigs - add_objects

I instantiate a container, 
add a nodes object to the container, 
add a node to th nodes.

At this point I can only add twigs though I think I should be able to add=
 nodes. I thought I would look at the SubOjbects list however the only=
 object that appears in the Subobjects list is nodes.

Am I missing something here? I have tried countless permutations with and=
 without the base class, deriving base from object manager etc... I think=
 one of my prior iterations actually worked but without the base class=
 concept though I seem unable to reproduce it now...

Does anyone have any ideas?

Thanks 
Bob

I am not sure what is going on but wouldn't it be generally safer if your
java class converts the encrypted cookie in some ASCII text format first?
I think that will solve your Zope problem too.

In general the process is:

- create a database adapter
- create a zsql method to do the insert
- create an html form to submit the data
- create a dtml method to call the zsql method as the form's submit action

Here's a pretty good how-to that describes the entire process in detail.

I find these pages to be an essential reference for zsql:

Hi Jeff.

Can you post the traceback. If this is the error I think it is then it may be
related to what you set as your SMTP server when you created the WorldPilot
object. One thing I found that works reliably is to specify   localhost  for
the SMTP and IMAP servers. 

BTW which IMAP server are you running? and what is your SMTP server?

Good Luck!

Being explicit.  Also, your method might not (depending on how you use
it) be being called from ZPublisher (in which case REQUEST is not
passed, it must be acquired), then again, your method might not be in an
acquisition context either, in which case you must pass it.  In 99% of
the cases however, you can do either.

Well, hanging is probably not the best way for Zope to handle this
situation, why it hangs I couldn't tell you (perhaps you should post
that to the collector).  However, form data usualy comes from a POST,
and here your doing a GET, passing a query string.

You can still get form data that way, the form attribute of REQUEST is
when you want to make sure you're definatly getting a value from a form
and not some other namespace.

Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF38C@ap3expr3applge.appl.ge.com>

I went ahead and wrote a Java helper class to convert from base 8 to base
10.  This has resolved the problem.  For those interested:

private static String convert(String uid)
	{
		
		StringBuffer sb = new StringBuffer();
		StringTokenizer octalString = new StringTokenizer(uid, "\\",
false);
		Integer convert = new Integer(1);

		while(octalString.hasMoreTokens())
		{
	
sb.append((char)convert.parseInt(octalString.nextToken(), 8));

		}	
		return(sb.toString());
	}

I am still curious as to why Zope converts the data into base 8.

Thanks for your response.

I keep forgetting that Zope is a collection of products :-(.  One day,
I do intend to spend more quality time with the source and how the
components interact.

Oddly, it only appears to do that when I call the external method
directly.  If I place <dtml-var "frobnicate(REQUEST)"> (modified to
pass in REQUEST explicitly) into a Method or Document and request
that without parameters, it comes up immediately and correctly.
Odd.

Will do.

Ahh, differing semantics.  I'm used to Python's cgi.py (and Perl's
cgi.pm, from memory) treating POSTs and GETs with query strings
the same.  The only way of telling the difference was by looking
at the REQUEST_METHOD (if you cared enough, that is).

This was my concern - REQUEST's namespace seems a little crowded, and I
was worried about clashing identifiers.

Hold the phone!  I've just constructed a document that basically does
<dtml-var REQUEST>, and invoked it with a query string, and the
parameters DO show up in REQUEST.form.  Are you pulling the wool over
my eyes, Michel?  :-)

Regards,
  Daryl Tester

PS - The recent "Virtual folders / URL" thread solution you proposed
was _very_ enlightening, but yet reading about direct traversal in
the ZSQL manual didn't provide anywhere near the same lightbulb factor.
Could Digital Creations consider adding that in as an example?

Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF372@ap3expr3applge.appl.ge.com>

All,

Have been trying to add File Attachment functionality to the ZDiscussions
Product.  Thus far, I have modded the ZDiscussions.py file, specifically the
ZDItem class's __init__ method, to accept one extra parameter called file.
The corresponding DTML-Method (postForm) within the ZDiscussion object has
been modded to include a FILE input field.

To facilitate the file handling, I am using the Squishfile.py module.  All
is working well, and via a new def attachment(self) method that was added to
the ZDiscussion.py module, I am able to return the file to the browser.

Herein lies the problem.  How can I reference the file via an HREF?  With
the following DTML:

<dtml-if attachment> 
	<b>Hello there</B>
	<tr><th bgcolor="#d0d0f0" align=left>Attachment:</th><td>
	<dtml-in attachment>		
		<A HREF="./<dtml-var file_name url_quote>">  
		<IMG SRC="<dtml-var SCRIPT_NAME >/<dtml-var icon >"
HEIGHT=16  
		  WIDTH=16 BORDER="0" ALT="Click to download
attachment"></A>    
		<A HREF="./<dtml-var file_name url_quote>">  
		<dtml-var file_name></A>   
		<dtml-var file_kbytes>KB (<dtml-var file_bytes> bytes)<BR>  
	</dtml-in attachment></td>
</dtml-if>

This of course references the file object as
absolute_url/ZDItem_id/file_name.  This same reference url is used in the
Squishdot product when displaying a link the user may click on to download
the file.  However, in my implementation it is not referencing the file.

The only way to reference the file is to use <dtml-var attachment>, which
means that the file will be streamed to the user as soon as they click on
the message thread, obviously not the way I would like to handle the
situation.

Do I need to include the file object as a property of the message?  I
thought by including the file object during the creation (__init__) method
of ZDItem this would be handled.

Any/all assistance would be greatly appreciated.  Also, if I am crazy for
doing this please let me know.  Perhaps a new ZDiscussion already exists
that supports attachments?

Thanks again,
-Brian

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,

Michael Bernstein.

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,


[RH]Michael,

What you seem to be descibing is some sort of an internal Zope 'link base'
as they exist for may hypertext systems (but zopish). This would be very
useful.
I do have some doubts about your desciption, however:

- would the generic relationships (meta-type<->meta-type) you describe be
the best way to go and whether they would turn out to be very useful. You
also do not mention one-to-one relationships; I'm sure this is not on
purpose, but this could be implemented quite simply by a specific python
product.

- I also wonder whether much of what you describe cannot also be achieved in
other ways, mainly through using the Catalog (as you indicated yourself). If
I may speculate a bit more on this point: what you want may be a specialized
folder index method that uses a mix of its own objectValues and Catalog
obtained objectvalues for its contents. If you wanted to use symlink type
relations, this may be done by using properties (this is more or less
generic) or by using the values of a 'link base' type of object (see above).
THis last would be very specific: pointing to specific objects.

- The idea of relationship aware is nice, but the drawback is that it can
only be true for derived ZClasses, and not all zope objects are Zclasses.

- In ZDP list many of these subjects have been in question for some time
now. You may want to have a look at the list archives of last month for many
of the discussions and of course the implementation of ZDP Tools by Maik
Roeder (available somewhere from his member page:
http://www.zope.org/Members/roeder)

Hi,

Wasn't it generally agreed that storing a counter in a ZODB was a bad idea 'cos of the high number
of refreshes, and hence the number of transactions stored in DB?

Basically, because of the undo/rollback capability of ZODB, the data.fs grows rapidly if you use it
to do counter-type things.

Or an I wrong?

I am using Zope for an large  project at the moment. For static content, 
such as images, I use apache to server them up (and will probably move
to something faster such as thttpd or kernel mode http server) and then just store
a URL reference to the actual data. This leaves zope to do presenatation, which it
does really  well and let a more suitable server handle the static content.
Any way, I'm not saying that zope couldn't handle this however depending on
 your exact use this may be an option for you.

Cheers,

Benno

You can help yourself by consulting the archives of this mailing
list:

The solution is to patch MySQLmodule.c to make it compliant with
mysql.h of newer versions of MySQL.

You can find my (unofficial) patch in the archives of the mailing 
list at

DTML-LET is meant for renaming expressions, like a macro

so when you do

      <dtml-let name="bob"
                relation="uncle">
        <dtml-var name> is your <dtml-var relation>
      </dtml-let>

what actually gets evaluated is <dtml-var "bob"> is your <dtml-var "uncle">,
which is nice.


the other part <dtml-let x=5 y=7>

is rewritten to <dtml-var 5><dtml-var 7>

which is not nice at all as there is no variables called 5 and 7.

OTOH 

      <dtml-let x="5" y="7">
        <dtml-var x><dtml-var y>
      </dtml-let>

should run fine as then x and y are expressions and not variables 
so 
<dtml-var x><dtml-var y> is <dtml-var "5"><dtml-var "7"> which runs fine.

Subject: [Zope] security question
Message-ID: <001401bf900d$0e049860$1464a8c0@sabine>

hello:

for my zope, the root directory is protected so that anonymous users have no
permissions.  in addition to root, two other users are defined and given the
role 'internal'.  one of the users has a username/password.  the other
allows access based upon IP range.  this works as intended.

i now want to give anonymous users permission to access
/subfolder/index_html.  this dtml method accesses a database and uses
LocalFS.

my first attempt to realize this was to assign the appropriate permissions
to Anonymous for index_html.  when this failed, i went to the /subfolder
security and modified permissions there that seemed relevant.  i tried many
combinations until finally giving up and granting all available permissions
to Anonymous at the /subfolder and /subfolder/index_html levels.  so now,
all permissions are checked for 'acquire' and for 'Anonymous'.

even this does not work!  users attempting to access
http://myzope/subfolder/index_html are greeted with an authentication
dialog.

so, despite the fact that security seems to be a pretty simple concept i
seem to be missing something fundamental.

any insight would be appreciated.

thanks,
bac

Security is never a simple concept, especially in system as complex as Zope.

Some decent documentation would help ;-)

Stupid bug :-)
here is the patch against
lib/python/Products/jcNTUserFolder/NTUserFolder.py:

164a165
>         userobjects = filter(None, userobjects)


if you don't have patch.exe (which is likely to be the case, as you run Zope
on Windows...), the above patch means that you have to add the line
userobjects = filter(None, userobjects) at line 165 of the file so the code:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        return userobjects

is turned into:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        userobjects = filter(None, userobjects)
        return userobjects

You could also download the latest jcNTUserFolder-0.0.4 at
http://www.zope.org/Members/jephte/jcNTUserFolder

Remember: Zope must run as a service or the user have "act as part of the
operating system" for jcNTUserFolder to work!

Message-ID: <200003171426.JAA22832@saltmine.radix.net>

[I'm posting this again because, suprisingly, there was no response]


I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute)?

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

I would add to this that Relationship objects, or rather the unnamed
sub-objects which actually hold the data for individual pairings, should
have properties in their own right.  A relationship (especially many-to-many
type) can have information associated with it which properly belongs to
neither of the related objects, such as 'advance amount' for an Author
relationship.

It isn't clear to me that Relationships is really the right way to do this,
but if someone wanted to code it I'm sure people would try it out.

I'm guessing that Steffen is using the "default" start script, which passes the
"-D" parameter to Zope -- it is therefore running in "debug mode", and writing
error messages to the console.  Backgrounding it will work, sort of, but will
leave Zope expecting to write to the controlling tty -- if it goes away (i.e.,
Steffen logs out), then Zope will die hard when trying to write to it.

A better fix is to edit the start script and remove the "-D" from the command
line.  Without the "-D", Zope will daemonize itself, and the backgrounding won't
be needed.

I'm trying to build up some variables from more than one form which are to

saving them in a SESSION variable using SQL Session (I can save them OK) 
but then of course I have to get them back into something which an SQL 
Method can understand. I'm stuck at this point.

Is there any way to pass the SESSION variable into an SQL Method ??

Or, if not, How do I get the values back from SESSION so that I can call an 
SQL Method ?

No, it is not supposed to be in the list. Zope is not SSI, nor does it try
to be SSI compatable. Zope does have analogous variables, though. For
example, when I navigate to http://my.server.com/jeff/dumpRequest, I get:

  URL0 = http://my.server.com/jeff/dumpRequest
  URL1 = http://my.server.com/jeff
  URL2 = http://my.server.com

  BASE0 = http://my.server.com
  BASE1 = http://my.server.com
  BASE2 = http://my.server.com/jeff
  BASE3 = http://my.server.com/jeff/dumpRequest

  PATH_INFO = /jeff/dumpRequest
  PATH_TRANSLATED = /jeff/dumpRequest

Since I haven't done much with SSI in the past, I don't know which one is
similiar to REQUEST_URI. If I had to guess, I would say PATH_INFO is the
one you are looking for.

Try this:

<A
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80&dtml-PATH_INFO;;weblint">Link
Text</A>

or,

<A href="http://validator.w3.org/check?uri=&dtml-URL0;;weblint">Link
Text</A>

Obviously, the second is preferred, since it is both more clear and
requires less maintenance (the URL is not hardcoded, so if your server
changes from dnrdb.cbi.tamucc.edu to newserver.cbi.tamucc.edu, the code
would not require change.)

One succeeds, the rest fail.

(I presume by 'it' you mean Zope)

Zope is, it's default storage, FileStorage, is not.

Yes.

Well, that question can't really be answered.  First off, there is a
global python interpreter lock.  I don't really want to get into the
details here, but basicly only one thread of execution can be in the
interpreter at once.  This is a pretty major limitation in Python's most
popular implementation, CPython (which is what Zope is based on).

The interpreter will 'give up the lock' every N bytecodes or so, there
is some mechanism for you to control this.  Check the python site for
more details.

Your idea is not bad, as long as you use a Storage that is multi-process
safe like ZEO.  I'm not sure if having as many Zope instances as Apache
instances is necessarily a good idea, since Zope instances can become
huge, many times bigger than their Apache counterparts.  Given Apache's
nature to do lots of forking and pre-forking (yes, this can be
controlled) this might lead to immense memory requirements.

Values like this that you are looking for come from the front end web
server.  Most web servers pass a number of these variables into the
environment of a program that they are executing (in this case, Zope). 
The specification of what variables gets passed and how is called Common
Gateway Interface (CGI).

REQUEST_URI is not part of the CGI/1.1 (the most recent) spec.  I
suspect you are used to programming in some sort of SSI environment
where REQUEST_URI exists as a convienience for programmers.  I do
believe I recall REQUEST_URI being a variable in Apache.  This
convienience does not exist for Zope because it is not a standard CGI
variable and Apache does not pass it to Zope or any other CGI program. 
There is, in fact, probably some other standard variable that does the
exact same thing as REQUEST_URI.

The list of standard variable can be found at:

Subject: [Zope] Odd AttributeError (__call__)
Message-ID: <38D294FE.357B2DA4@harlan.frohwitter.com>

I have three instances of Zope running on three different machines (all
dual PPro).  On the first two machines, a simple <a
href="otherfolder">Click here to move to the other folder</a> works just
fine to hyperlink to the index_html in the "otherfolder" folder. 
However, on the third machine (ironically the one that I want to deploy
to) the same hyperlink encounters the following error:


           
           Zope Error

           Zope has encountered an error while publishing this resource. 

           Error Type: AttributeError
           Error Value: __call__



In all three instances, the security is set up the same way on all
documents, images, and folders accessed.  Incidentally, the deploy
server and one of the working ones are running Zope 2.1.4.  The other
working one is running 2.1.3.  Does anyone have an idea what my problem
is?

Thanks in advance,

Ron

AUTHENTICATED_USER is an object created after a client authenticates, it
is not an http header nor is it derived from the Authentication header. 
The Authentication header contains a user id and base64 encoded password
that is used to authenticate the client.

I assume by 'packet' you mean request.  HTTP is stream based.

No.  You can authenticate yourself with such a client, but you must
still have a valid password.  You cannot just insert any old user id
into the Authentication header and expect Zope to believe you.  That
wouldn't exactly be very good security.

Subject: [Zope] Zope 2.1.5 release and *security update*
Message-ID: <613145F79272D211914B0020AFF6401914DE7D@gandalf.digicool.com>

Hi all,

Zope 2.1.5 has been released - you can download it from
the usual place on Zope.org:

http://www.zope.org/Products/Zope/2.1.5/


This release fixes two fairly important security issues 
that have recently come to our attention:

  o It was possible for a Zope user with a fair amount of Zope 
    zen and permission to create DTML documents and Folders
    to circumvent the security machinery within DTML in certain 
    situations, possibly giving the user the ability to use 
    resources that he wouldn't otherwise be able to access via 
    DTML.

  o It also came to our attention that the DTML code in 
    ZSQLMethod objects was not subject to the same security
    constraints as the DTML code in DTMLMethods and DTML 
    Documents.

The 2.1.5 release fixes both of these issues and we highly 
recommend that you upgrade, especially if you use Zope for 
sites that allow untrusted users to create Folders and DTML 
Documents or DTML Methods.

The release also includes a number of recent bug fixes, 
including the problem in TimeStamp objects that caused 
the bobobase_modification_time() of Zope objects to 
appear to be a day behind. Note that this release contains
two binary changes, so those running Zope from the source 
release will need to rebuild the Zope extensions after 
applying the update. The fixes are also available in CVS 
and binaries will need to be rebuilt after the update for 
those of you using CVS.

Note that with the 2.1.5 release we will also be releasing
"diff" updates as .tgz files that will let you easily 
upgrade an existing 2.1.x site. These updates are available 
for those currently using the 2.1.x source release or the
2.1.x binary releases for either solaris or linux (diff 
releases are not available for win32 for now).

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

As far as authorization goes, I've noticed that I get prompted for a
user-name/password only once during a session.  After you've been validated, it
appears zope does not prompt you again for that browser session.

The reason I'm concerned is that if I have to do maintenance on someone else's
web browser, how do I ensure that after I leave a person cannot use the back
button or history list to gain manager access to the site?  Do I have to exit
the browser when I'm done?

Daniel,

THis is a limitation of HTTP basic authentication and is not a
Zope-specific problem.

Either quit the browser before you leave or write a short dtml method:

<dtml-raise Unauthorized>
Logout
</dtml-raise>

and call it before you leave.  Note that you need to call it, then click
"OK", or you will still be logged in.

Actually Zope does prompt your client on every single request (that
requires authorization), it must, because HTTP is stateless.  Zope also
validates every single request.

This is a 'feature' of the HTTP Basic Authentication spec that says
browsers can cache auth information.  It is however often a lack that
browsers do not let you manually clear this cache.

Yes.  Or force the client to discard it's cached auth info with a
<dtml-raise Unauthorized></dtml-raise>.

Yes, you can nest dtml-in's and you pass the parameters to the SQL
method by explicitly invoking it as an expression, not just as a
name.  (It happens that I asked a very similar question of this list
recently, which is why I now know the answers.)  My example, stripped
down a bit, looks like

<dtml-var standard_html_header>
<dtml-in search_author size=50 start=query_start>
  ...
        <tr>
          <td class="center"><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
          <td><dtml-in expr="return_authors(seq=seq)">
                  <dtml-var name>;
              </dtml-in></td>
        </tr>
 ...
</dtml-in>

I hope this is enough to get you started.  Contact me directly if you
would like more explanation.

I am having some trouble getting Zope to work with a MS SQL Server database.  I can set the ODBC connection on the server and then add ZODBC connection to a folder matching that connection.  I can browse the new connection and see the tables, but when I try to test any simple SQL I get the following error:

Yes. Assuming that you're using basic HTTP authentication, restarting the
browser will clear everything out.

The key to figuring this behavior out is understanding how ZPublisher maps
a URL:

 * Split the URI path into a sequence of names

 * From the root, traverse each named object in order (allowing
   it to intercept the traversal, if it wants).  Traversal requires at
   least minimal permissions on the traversed-through object.

 * During traversal, allow the acquisition machinery to operate

 * If the last item traversed to is callable, call it;  otherwise, render
   it.

This works somewhat like permissions on a Unix directory:  you have to have the
executable bit set in order to traverse the directory, and the read bit set in
order to list it.

Hope this helps!

 Thanks.  I would think then this password is succeptible to the same pitfalls
as  sending clear text passwords over  the network which can be stolen. In
which case making users to use https is a good idea ?

Message-ID: <Pine.LNX.4.10.10003172246500.10594-100000@yoni.northernwastes.org>

So...

I'm sure the answer to this question is painfully obvious, but I've
pounded on the docs and I can't find it for the life of me.

I have created a subclass as per the instuctions in the Zope Developers
Guide.  I am doing this specificly to avoid my inner class polluting the
global product list.  (There will ulimately be a large number of these
inner classes if I can figure this out.)

So far, so good.  Using the dtml-var tag I can display any property of any
instance of my newly created subclass.  But I also need to build a table
that iterates though all instances of this subclass and displays several
of it's properties.

I suspect this involves the use of the dtml-in tag, but I can't for the
life of me figure out what the syntax should look like.  The discussion of
dtml-in tag seems to imply a list of objects in a folder, and what I have
is a list of subobjects in an object.

Hints anyone?  How-To?  FAQ?


TIA,


Geoffrey L. Wright

When Zen borders on Kamikaze.....

DTML Document --> product method --> DTML method

I've been banging my head against this for 4 days in a row now. I want 
to call a DTML method, via a product method, from a DTML document, but
I don't succeed in setting the client namespace for the DTML method to 
the original DTML Document's namespace.

I'd appreciate any help!

I have a DTML document. It has a valid aq_parent. From this DTML document, 
I'm calling a product method, passing the DTML documents's aq_parent as
an argument:

<dtml-var "NFGnavCore.aqqy(aq_parent)">

This method has access to the aq_parent object all right, tested
OK. Next, the DTML method is called from the product python method and
the original aq_parent object is given as the new acquisition context:

	def aqqy(self, context=None):
		""" some test method"""
		retval= "Hi! I'm the aqqy method, called with context.id <b>%s</b>" % context.id
		return retval + self.aqqy_helper(client=context)

The DTML method 'aqqy_helper' is called all right, but has no access
to the context object passed in. Any attempt to access objects that
should be in the acquired namespace, for example:

		 My aq_parent id= <dtml-var "aq_parent.id">

results in an error message:

          You are not authorized to access aq_parent. 

Which, if I'm not mistaken, is caused by the validate routine called 
from OFS/DTMLMethod.py as documented in 'oldvalidate()':

        if inst is parent:
            raise 'Unauthorized', (
                'You are not authorized to access <em>%s</em>.' % name)

So what am I doing wrong, and what is the right way to call DTML
methods from product methods?

Well, this gives you the ability to create, for example, 'Car' and
'Bicycle' objects, and designate them both as meta type 'vehicle', then
create an 'Owner' relationship between 'vehicle's and 'Person's. A
trivial example, to be sure.

I suppose the relationship objects could be 'instrumented' to allow
other types of filtering criteria. Whatever the criteria though, the
possible objects need to be presented through a 'relationships' form
within the ZClass instance.

You're right, one-to-one relationships should be implemented as well,
but as you noted, this proposal is not as critical to implementing
one-to-one relationships as it is for many-to-many.

That's pretty close. My proposal actually has two levels of indirection:
first the relationship objects that are relevant to the ZClass are
obtained from a ZCatalog like object (the relationship folder in the
control panel), and then those relationship objects (themselves
ZCatalog-like) are queried to obtain the objects that the ZClass
instance is associated with. Then you should be able to access these
objects' properties and contents as if they were contained within the
current object's relationship:

<dtml-in Author>
<dtml-var name>
</dtml-in>

By doing it this way, you can add relationship types between you classes
as your application grows in complexity without having to re-instantiate
all your objects. All you would have to change would be the add/edit
methods in the ZClass, and whatever viewing methods that you want to
expose the new information (other than the relationships tab in the
management intrface).

Neither approach would give me the ability to refer to linked to objects
as if they were sub-objects. This is critical for the simplicity of the
DTML to access the associated objects' contents and properties. In
short, I want a pseudo sub-object that acts as a proxy for the real
object, not a symlink I can follow or resolve to access. The end result
is much the same, but the semantics are radically simpler with my
proposal. Note: associated objects should NOT appear within the
'Contents' tab.

First, relationship_aware is optional; all it's absence means is that
the object is not aware of it's outgoing relationships. Other
relationship_aware objects could refer to it with no problem. Second,
if, for example,  you want a relationship_aware Folder, just subclass
Folder and relationship_aware in a new ZCLass.

Zope doesn't know how to call or execute php code.  To do this, you need
to have Zope make an 'external' http call back out to Apache, which will
execute the php code, return it to Zope, which returns it to your
client.

Here is a good how-to on it:

Hmm. This update has broken all my zsqlmethods I've tested so far.  I've
reverting to 2.1.4.

Eg when testing from the management interface:

File D:\zope2\lib\python\Shared\DC\ZRDB\DA.py, line 459, in __call__
    (Object: sqlShowComment)
TypeError: too many arguments; expected 4, got 5

SQLSESSION has also died with this version release.

I couldn't find 2.1.4 on zope.org, but had a copy of 2.1.3, and that has

Can you describe how it is broken?  Is there a traceback?  Are both

Notice that line where it refers to RSSChannel.py. It's pointing to the
RSSChannel.py file in my previous (2.1.4) version of Zope. Odd.

However, it might have something to do with the fact that when I installed
2.1.5 I didn't untar a fresh copy of RSSChannel, but copied it to the new
directory instead. I did that because I'd made some changes to
RSSChannel.py and another file and didn't want to redo them. I did a 'cp
-a' if memory serves.

I was under the impression that you could copy the directories in
lib/python/Products/ over to a new Zope. Obviously it didn't work in this
case.

Can anyone help?

I think integer division was covered last week on this
mailing list.  Change 1/24 to 1.0/24 (the upshot is 1/24 is
evaluating to 0).

Fabrice,

I ran into similar errors.  Here's the response from Jo Meder that helped me
get MySQLDA compiled:

I suppose line 1125 of mySQLmodule.c is something like:

	tf = & (mysql_fetch_field_direct(self->res,j));

If this is the case, try applying the following patch to your
MySQLmodule.c (this is strictly "works for me"):

------------------cut here-----------------------------------------
235c235

Subject: [Zope] Looking up object instances in a folder
Message-ID: <38D4C514.ED1D3EB5@funcom.com>

I have some instances of my own ZClass in a folder, and I can iterate
over them using:

<dtml-in "somefolder.subfolder.objectValues()">
  <dtml-var title>
</dtml>

The instances are stored using auto generated ids (simple numbers).

In addition to being able to iterate over the instances in the folder, I
also need to access an instance directly by using its id which is passed
in the REQUEST object, but so far I have been unsuccessful. What I am
trying to do is something like:

<dtml-in "somefolder.subfolder.getInstance(REQUEST.id)">
  <dtml-var title>
</dtml-in>

but I have not been able to get access to just the one instance (but
iterating works fine as mentioned before). Could somebody with a clue
give me a hint?

Thanks in advance,

   The ZMySQLDA is used (and will be used) by so many people that this
information should be packed into a HOW-TO and published along with the
very DA.

Subject: [Zope] Find object in a directory question
Message-ID: <20000319141420.A2559@mimar.demon.nl>

Hi,

I've created a ZClass 'CLink', which contains a URL, title and such things.
In my dtml-pages, I can do <dtml-var slashdot>, and the slashdot-clink
object will insert the <a href=...></a> stuff for me. I've got this 
working using the Renderable class. 

I've planned to put all CLink objects in the /links folder so I can
automatically create 'bookmarks' out of the links I reference to. I also
want to be able to categorize the links into subfolders, so I want to have
a links.sports.ski.resorts directory with ski resorts, and a
links.news.nerdish folder for nerd-related news. 
I can use <dtml-var links.news.nerdish.slashdot> to refer to the slashdot
object that way. 

However, I want to easily change my categories, without changing all
<dtml-var ...> that reference object in the categories. So I figured, I'd
make it <dtml-var links.find('slashdot')>. This should one day be the same as
<dtml-var links.news.slashdot> and the next day the same as
<dtml-var links.news.nerdish.slashdot>. With my external method (which only
looks in the current folder so far), I can't get this to work. 

Any ideas? Would the same be easier or simpler using a ZCatalog? 
Refering to a link should not be too much typing. 

As an extra question: is it possible to refer to an object in multiple
places, like softlinks (or hardlinks) in unix? Suppose I have a folder with
'My Frequent internet-visits', and 'News', they could both contain the same
CLink. Is that possible in zope?

Well, hope I made anysense..
Thanks,
    Chris Niekel

   It seems on one of my computers the problem went away whe I tried to

test linux installations later.
   I have problems upgrading to 2.1.5 - initially Zope came up well, but
when I tried to install 3rd-party modules (including SiteAccess) - I could
not login. I didn't traced the problem to SiteAccess or other product yet...

the register DTML method of zope.org. Is the DTML source for the user

can be inspected this way, but why not these pages? This can't be such a

Thanks for any hint.

   These pages probably written in Python, hence there is no view_source
for them.

Subject: [Zope] Property Sheet access from Python Products
Message-ID: <200003191153560734.0E5EF386@iqtinc.com>

I am creating a product in Python and I want to use property sheets. I am able to add sheets and add properties to those sheets. However how I have to access the property sheets differently than if I was accessing property sheets on a ZClass programmatically. I suspect that I am perhaps not using the right mixin classes.

For instance, I have a property sheet 'Private' with an attribute 'prop1'
If I create this in a ZClass, I can use 
<dtml-var prop1> to access my attribute.
in my class I have to do the following
<dtml-var "propertysheets.get('Private').getProperty('prop1')"><p>

likewise in Python code I must access the attribute using 
self.propertysheets.get('Private').getProperty('prop1')
where in a ZClass I could do 
propertysheets.Private.prop1

My class declaration is as follows mixins:
class base(ObjectManager,PropertyManager, 
    Acquisition.Implicit,
    Persistence.Persistent,
    RoleManager):

Am I missing a mixin somewhere? Or do I have to access the attributes differently from a Python Class?

Thanks 
Bob

Could you give us some more detail?

First of all, and this was probably just a typo on your part, but the two
products will appear in the "Available Objects selection list", not in an
"External Methods" list.

If they don't appear there (after restarting Zope), go to the Control Panel
and click on Product Management at the bottom of the page. If the installs
of Squishdot and TinyTables are busted you'll see them listed as such on
this Product Management page. Click on each broken item and send what it
presents you with to this list. Someone will be able to help with it at that
point. What I've just described is the procedure for debugging a failed
Squishdot install per it's installation instructions.

And you do see a folder for each of these products in your
zope/lib/python/products dir, right?

Hello all,

I think I have Zope running. I can get to the localhost:8080/manage page
and go into the Control Panel and External Methods.  I've tried to
install TinyTable and Squishdot by untarring them in /var/zope with
subdirectories preserved. No go -- they don't seem to show up in
External Methods as they say they should by the Squishdot Install guide.
Can anyone help?

Ahh, thank you. The Squishdot documentation is quite non-specific and says
you'll find it in Available Options.  The first Available Options I found was
under External. I see them now and have created a Squishdot site selecting the
demo.  Not sure how to get to the first page of the demo which I've put at
localhost.  Can you tell I'm new? -- IV

Learning Python is a great book if your new.  I had a chance to look at
Python Essential Reference before it went to print and it is also an
excellent book and well thought out reference.

I saw the same problem under 2.1.2.  What was even odder, I deleted my
equivalent of NewTestVersion, and recreated it.  After entering the
version, my browser still said 'working in TestVersion'.  Restarting
the browser fixed that, so it must have been some sort of caching

Message-ID: <003601bf91e9$0c1d5680$265eb5cf@kevin>

I've built an application with ZOPE and would like to create a Java
interface to it (probably using jpython/wxWindows)

Here's how it should work:

When changes are made on the ZOPE site by a client, a notification is sent
from ZOPE to the Java interface and displayed in real-time. The idea here is
not to have a continually refreshing Java window, but a window which updates
only when it receives a message from the site to do so.

What I don't know is how to send the data from ZOPE to the Java client.  Can
anyone point me to any existing ZOPE Products/Projects/How-To's which are
similar to what I've described, or perhaps point me in the right direction?

You could always put the values you've already accumulated into

This is because Zope has challenged for a username/password, and KFM doesn't
handle that nicely.

Either put http://user:password@localhost:8080/manage (iirc - there is a HOWTO
about this) or use a more sophisticated browser, like Netscape (but beware the
memory leaks when editing textareas. ):

David,

In order to use the management screens, you need to use a browser that
supports HTTP basic authentication.  To my knowledge, KFM does not
support this.  Use Netscape or Mozilla.

Hmmm.  Tried that, but still no luck.  Zope give me a
NameError, and tells me method is trying to reference a
nonexistent variable (fullname).  Here's the current
draft of my code:

<table>
  <tr>
    <th>Name</th>
    <th>Description</th>
  </tr>
  <dtml-with bwlib_abilities>
    <dtml-in "fullname('AbilityClass')">
      <tr>
        <td><dtml-var fullname></td>
        <td><dtml-var description></td>
      </tr>
    </dtml-in>
  </dtml-with>
</table>

Where bwlib_abilities is the name my container class,
AbilityClass is the subclass in question, fullname is
the sorting criterea and a poperty of AbilityClass, and
description is also a property of that subclass.

I know I'm hanging on something silly here, but I can't
for the life of myself figure out what it might be.

Also (as a more general sort of question):

Is this way of organizing data (ie, a bunch 'o
subclasses in a container class) a reasonable way to
deal with lists (50 to 100 items) of quasi-dynamic
objects?  I'm from more of a more traditional database
background, and am used to putting this sort of info in
a table.  But in the case of this particular app, ZODB
seems idea since it provides several less technical
users of the app a ready-made interface to these objects
and I don't really need access to this data outside of
this single app.  But there seems like an almost
daunting amount of flexibility in the way I might
organize this data -- objects in folders, subobjects in
container objects, zcatalogs, etc.

Thanks,

That behavior is expected. As far as I remeber, KFM (in the 1.x versions) 
does not support HTTP authentication. 
Furthermore, 
http://localhost:8080/manage?__ac_user=superuser&__ac_password=PASSWORD did 
not work for me either.

I don't know how KDE 2.0' new konquerer will handle it. But as much as they 
worked on this application, it will work there. Can anyone confirm that?

Stephan

sha is an optional python module.  Presumably it wasn't included
in Modules/Setup when you compiled your python, or wasn't included in
the binary set if you got a binary distrabution.  (It should
be a dynamically loaded module).

The module is used if you request sha encryption on the password.
If you choose some other encryption type the sha routines won't
get called.  So as a quick fix you could remove the sha from
the import line.  But you probably really want to recompile python
to make sure that all modules Zope uses are included.  Hopefully
there's a list somewhere, though I can't recally seeing one...I just
enabled all the modules I could <grin>.

Message-ID: <Pine.BSI.3.96.1000319220658.3933H-100000@twirl.bitdance.com>

There was a recent mention of using Lynx to access the management
interface of Zope.  I'd like to use w3m.  It produces a more pleasing
page given all those little spacer images Zope uses.  Also, it
automatically launches vi for me when I hit return on the edit
screen's text input area, which is *way* cool <grin>.

However, it doesn't seem to be handling the management interface
correctly.  If I descend into a management link, I get the 'view'
panel for the link instead of the manage_main screen.  Worse,
I tried to 'rename' an index_html method, and it renamed the
index_html in the *parent* folder!  This is most weird.  Anyone
know what Zope could be emitting that w3m is not handling correctly?
I'd guess redirects, but I'm surprised I end up in the view screen
in that case...

I'm currently running w3m beta-991203.  Anyone know if whatever-it-is
is fixed in a later version, assuming there is one?

This is w3m's fault, it does not send the Authentication header to
frames in a frameset, just to the frameset.  Zope calculates
'manage_workspace' based on various factors, including whether or not
you are authorized to access the managment view.  Since you are
effectivly 'anonymous' in the frame it shows you the anonymous view. 
Uncheck 'View' for anonymous and you will probably get a 401
Unauthorized.

I don't think it's Zope's fault.  In this case, w3m is probably ignoring
or not understanding the <base> tag.

You are either not using the right python, or you are using an old
python.  Python 1.5.2, including the python that comes with Zope,  comes
standard with the sha module.

It's now a standard module as of 1.5.2.  I presume matt is using an old
python or turned off sha.

i got the setup running on rh6.1, running userdb (cookie auth) for
authentication, run start as root.  i've chmod -R nobody.nobody * in Zope.  i
copied my previous Data.fs to replace the Data.fs that comes with
Zope-2.1.5-src.  will this be the cause?  i've been upgrading this way since
2.1.0
i did run with -D, but saw no error.

I knew it was all w3m's fault, since it all works in other browsers <grin>.

Thanks for letting me know what the likely problems are.  Whether or
not I'll have time to do anything with the information remains to be
seen.  I wonder, though...I'm starting from the manage_main URL,
not the manage URL, so the page I'm starting from doesn't have
a frameset as far as I can see.  Descending into a folder works,
but descending into, say, a DTML_method gets me the view.  Well,
I'll have to just ignore the whole thing for now.  w3m is a nice
browser, I hope they get these bugs worked out soon.

I do still find w3m useful, though.  Since it's U command to go
to a new URL does accept relative specifications, it's pretty
easy to use that to descend into the 'manage_main' view of
the items I'm interested in.

I'm trying to use etcUserFolder, and I want it to actually authenticate
off of /etc/shadow. saying /etc/shadow as the Password File doesn't
work, presumably because Zope is running as nobody.  Is there any way I
can let just etcUserFolder run as shadow?

On a similar note, am I doing something terribly stupid/compromising

You can just use File objects to store the flash content, and refer to the 
objects from HTML the same way you would from a static HTML site.

I wrote a special Python object for it, inheriting from File, just so it 
would take care of its own HTML tag, just like the Image object does. 
This because the site in question contained quite a lot of different Flash 
objects, and the widths and heights changed sometimes during the course of 
the design. The designers just had to upload their flash content into these  objects, which they very quickly got the hang of.

However, for the one Shockwave game in the site, I just had the Shickwave developer upload to a File object, and the HTML for it was handcoded into the reffering HTML page.

No, that is the best way. Note that you don't have to give that user a password, and that for users from the specified set of IP addresses the authentication will be transparent.

when I was cataloging my zope site and was editing i did get a conflict
'competing' writes, which reminded me: how many times does ZOPE try to write
to the ZODB and then 'fails' and roll's back - is it 3? assuming this size
is configurable where would I go and change this?  when i was cataloging i
got this:
2000-03:20T03:24:27 ERROR(200) ZODB Couldn't load state for
'\000\000\000\000\000\000\350\217' <- this happens right before the
competing writes. could someone explain what this \xxx\yyy\zzz is?

and how do I redirect ZServer's console to a file?  I'm in DOS right now
(havent done this in awhile) - and tried to "C:\Program

that didnt work..  In linux I've tried redirectings stderr and stdout to a

I believe that is python's octal representation of an internal object
index.  The 'could not load state' means the ZODB tried to load
the object from disk storage and could not complete the operation.

I'm getting those on my own database and haven't yet had the time
to track down where they are coming from.  I fear some sort of
database corruption, but so far the system has continued to function
despite these errors.

And I can't get it to work at all.  etcUserFolder.py says to put a file
in a directory called etcUsers in the root zope folder.  OK, I made a
folder zope/etcUsers/, and copied my /etc/shadow to there.  Then I
edited it to just have a few names:passwords.  then I chowned nobody. 
This wasn't working.  I copied it to the directory of the product-
lib/python/Products/etcUserFolder.
No juice.  while from crypt import crypt worked on the command line, I
still copied cryptmodule.so to my zope directory.  No dice.  So I copied
it to etc's directory.  No juice.

etcUserFolder still tells me there are no users whatsoever. what am I
doing wrong?

Yeh, and now that ZSQLMethods don't work neither does GUF with MySQL - e.g.,
the following code fails:

  <dtml-in "sqlGetUserRoles(username=username)">
  <dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'].rolename)">
  </dtml-in>
  <dtml-return ret>

With the error message:

  "You are not authorised to access 'rolename'"

The method has a Proxy role with appropriate access to the MySQL method.  It
just doesn't seem able to access the results variable!?

I'm getting the same error on Zope 2.1.5. My zclass A which inherits object
manager. Inside it I have zclass B. When I try to create B object inside A
folder Zope gives me an Attribute Error: _getOb inside
B.createInObjectManager ()
It seems then Zope does not see class A's parent object manager. But, I have
exported A objects containing B object from 2.1.4 to 2.1.5 and that works.

There are no problems on 2.1.4. Classes are first defined on 2.1.4 an then
exported to 2.1.5.

Zope is built from source on RH 6.0, python 1.5.2

Message-ID: <20000320100802.14614.qmail@web4001.mail.yahoo.com>

Hi,

  I've tried to write one generic SQL method and
passing argument to my SQL method using dtml-let but I
got KeyError. I've tried it with dtml-with also but
same thing. 

In my page I use:

<dtml-let curpage=total>
  <dtml-call hitinsert>
</dtml-let>

and MySQL method is:

update zp_stat 
set <dtml-var curpage>  = <dtml-var curpage> + 1

What I want to do, is passing mySQL argument and 
using one method. Ex:

<dtml-let curpage=astro>
	<dtml-call hitinsert>
</dtml-let>

total and astro are INT in my SQL table.

I dont know if dtml-let is a right way?

Any suggestion to do this?

Thank's

You can't, unless Zope runs as root (which would be a very bad thing).
This is by design.

The best you can do is:
    1) Setup Zope to run as its own user (eg. user 'zope') instead of
       user 'nobody'
    2) Add a crontab job to copy the /etc/shadow file to where Zope
       can see it, changing ownership to user zope and removing group
       and other permissions.

If you run Zope as the nobody user, then the encrypted passwords will
need to be visible to this user, as well as any other processes that
run as user nobody which is not a good thing.

Message-ID: <4.2.0.58.20000320110253.00a07c50@192.168.0.2>

Hello,


I upgraded to Zope 2.1.5 (Win 32) Saturday and carried out changes in the 
database (eg. created new ZClasses, added ZClass instances, etc.)

I had a nasty system crash (Win 95) around midnight Saturday. When I 
reopened Zope I realised the database was back to its 16:22 status:
- All new objects had vanished.
- The last transaction logged in the Undo list is dated about 16:22.
- The very Data.fs in the filesystem is stamped 16:22 if you can believe it.

I checked the Z2.log and it shows these missing changes. So I didn't dreamt 
doing them.

I suppose these changes are lost?


Cheers.

This makes the shadow password suite worthless.
Assuming readonly access to /etc/shadow it's better to use a simple 
wrapper program that can do the access. This program should be carefully 
designed to not allow arbitrary input to compromise security.

One example is checkpassword (not for non-root programs) which is located 
at http://cr.yp.to/checkpwd.html
It's designed primarily to get a simple interface to various 
authentication schemes, but my be used as an example.

Subject: [Zope] Fwd: How do I set properties from DTML? (Repost)
Message-ID: <00031617304502.13146@promotor>

I'm reposting due to mail problems of my provider ...

I'm working on a thing I'll probably call "ZBox"; it's a "widget
method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Hi! 

I thought I'd forward this to the list in case it helps anyone else:

If you want to use FTP with SiteAccess then you'll need to add the following to SiteRoot.py, after
line 124 (at the end of the SiteRoot class), and at a similar place in AccessRule.py:

    def get_size(self):

Well, I've downloaded and installed Zope on my windows9x
and I can't run it. Of course 

there is no executable component. start.bat

and now ... how to use the zope on my windows9x and

Read the documentation at www.zope.org. I think the best is to start with 
the feature tour and then "Zope Content Manager's Guide".

Is this really what you want to do?  Under this scheme, user 1 views the
site, clicks on the maxamize box, and gets the rerendered page.  Now
user 2 visits the site, and sees the maximized box.  He doesn't want
that one, so he minimizes the box.  Now user 1 clicks to maximize some
other box, and suddenly his previously maximized box is minimized.

Or am I missing something about your design?

In any case, changing properties in this way to store state is going to
cause your ZODB to grow quickly as each property state change is stored
as a new, undoable, transaction.

It seems to me you want to use either some sort of Session product to
retain the state, or do what I suspect the tree product does and
put the state you need to set/save into the URL using argument
passing ("?xxx=yyy") or by using forms to submit the change requests
and storing the state in 'hidden' fields in the frorm.

Your need a list of the AbilityClass instances in 'bwlib_abilities',
which you can sort by fullname. Assuming 'AbilityClass' is the meta-type
of your subclass, try something like the following: 

<dtml-with bwlib_abilities>
     <dtml-in "objectValues('AbilityClass')" sort=fullname>
       <tr>
         <td><dtml-var fullname></td>
         <td><dtml-var description></td>
      </tr>
     </dtml-in>
</dtml-with>

Subject: [Zope] mimetools -- an example, I hope this helps
Message-ID: <H0001bac0796f0b3@MHS>

I had to play around to get mime stuff to work right.  I needed to email
messages to about 1500 people.  Every person reaceived a couple of documents
that were the same, and each person received one document that was unique for
that individual.  I also through in a timer loop to provide a one minute delay
between each email message.  (Our mail server could not handle the load.)  I am
enclosing the code that worked for me.  Of course ymmv :)


pull_contacts : this is an sql method which pulls user information out of an
Access database.  Most of the variables listed come out of this database.

dtml-log : I used the logger product to create some logs so that I could see
that my mail messages went out.  I don't think this worked the way I wanted it
to work.

mime tag :  I added some custom code to the mime stuff because the mime stuff
does not add the mime version 1.0 header.  This may not cause problems for
everyone else, but it does cause problems for HP OpenMail and Lotus Notes.  I
do not know if anyone has fixed this in the standard zope code, but it was not
working when I did this mailout.

"_[QUESTION].data" :  this was what I had to do to pull in the unique object
for each individual.  (I imported all of my documents into the zodb.)

that makes sense.

ok, this i don't get.  i'd have thought that since i opened
what i thought was my own instance of a Zope DB, using my own
FileStorage pointing to a file in /tmp:

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/foo.fs' ) )
	connection = db.open()
	root = connection.root()

that this would have nothing to do with the DB that Zope
was using for its internals.  all of the code examples i've
seen for ZODB are from python programs, and all include code like this.
if this *is* using Zope's internal DB instance, then that would imply 
that you can't use ZODB outside of Zope when Zope is running.
what am i missing?

> (why you are getting the

it appears that was unrelated.  i actually got my example to
work since posting.  the "unable to access" thing only happens
when i get an exception due to bugs in my code.

cool.  that's good to know.

indeed.  that's part of why i wanted to use a completely separate
database.  the other part is so i can use the same routines outside
of Zope, perhaps at the same time.

i'll try that.  thanks for your help.

thanks, i'll give that a try.  i don't really need a counter, at all.
it was just a minimal example to try and figure out ZODB.

That's very odd. I tried reproducing this and couldn't.

What do you mean by parent?  Presumably, A subclasses ObjectManager.
Right?

That's because export/import doesn't use createInObjectManager.
 
I suggest one of the following:

  - Try a very simple example that you can deacribe completely
    so you can explain it to me in complete detail and I can try to reporiduce
    it.

  - If your database isn't too big (or if you can reproduce this
    with a small database) send me the database. I'll look at it and see if I
    can see what's going on.

I'm not seeing this. What are you trying to add the ZClass to?
Zope 2.1.5 has a fix to ZClasses that makes it work correctly
with ObjectManagers, including ObjectManagers that don't use 
instance attributes to hold sub-objects.  All ObjectManagers should
implement a method, _getOb, that is used to get an object from the object
manager. If you are adding your instance to an object that is *not*
an object manager, then the above error would be expected.

Problem actually solved (by digging arount in how-tos). Some remarks:

Yes, I save the state of the boxes with their properties. Where else
should an object save its state? I mean, "state" IS a property of  the object.
In terms of object orientation, this seems to me to be a much more logical
design than to save session stuff in some non-zope external database or file.

O.k., my ZODB might grow, but is it really that much of a problem (I mean,
a problem that can not be solved by just packing the DB once in a while)? Any
experience with that out there?

The problem with concurrent users switching each other's boxes from one state
to the other only occurs if they use the same objects. What I use in my
implementation is seperate box objects in different user folders. Those objects
only contain stuff that is customized. All "heavy lifting" is done by methods
in the aqcuisition path, so that there is no real duplication of code even
though the complete box structure is duplicated. In a later stage, those objects
(currently just empty folders with a view properties ...) will become instances
of a class.

The cool thing about this is that the portal becomes extremely customizable.
You can add boxes only you can see, use different rendering methods,
style sheets, whatever can be put into a folderish object.

My idea is actually working quite well now. I'll try to make it a ZClass and
put it on the web. But first I want to do some testing.

As soon as I find the time for it, I'll put my ideas into a how-to.

Please disregard this. I didn't perform the test correctly.
I now can reproduce this. Stay tuned.

Subject: [Zope] posted part 2 of the zope memepool application
Message-ID: <38D64B95.99E1F5FA@sistelnet.es>

Hello everyone:

I have posted the second part (Use Cases) of the zope memepool project at
http://zope.sistelnet.es/memez

The final goal of this project is to have a completely functional
memepool-like application, product or whatever, built completely from
scratch, using Zope. The project tries to use a completle Object Oriented
approach to development, and (since I am no Zope guru) feeds from user
comments and recommendations.

Please have a look.

Sorry this update took so long, but this past month has been busy as heck.

Best regards.

Yes, what I didn't know about your design was that the objects in
question were specific to the user.  In that case, and if it is not
expected that the user will want to change his settings with every
session but instead this is a customization feature, then what you
have described sounds like an ideal application of Zope and its
object machinery.

I think it all depends on how frequent the updates are and how many
users you have.  If your site gets to be high enough traffic
and users make frequent enough changes for it to be a problem, you
could always switch to an undo-less backing store for the ZODB and
therefore not have to change your implementation to continue to
scale. Others with direct experience with portal-like sites may have
more useful input.

Are you, by the way, aware of the Portal Toolkit project?  I haven't
investigated it yet, but if you aren't following it it sounds like
something you'd be interested in.  I'm sure they are thinking about
scalability issues there.

I want to compare them has dates and not strings with the built-in cmp()

OK, so it's not my favourite editor but I thought I'd

Can anyone tell me what I should set EDITOR_CMD to?

'C:\WINNT\system32\notepad.exe' and 'C:\WINNT\system32\notepad.exe %s'
don't do the job. (What's the %s for anyway?)

The %s will be replaced by the filename. This so Notpad knows what file to 
edit.

You will have to double the bacvslahes for this to work, because in Python 
(as in many programming languages), the backslash has special meaning:

  'C:\\WINNT\\system32\\notepad.exe %s'
 
or, you could place an 'r' in front of the string (r stands for raw):

  r'C:\WINNT\system32\notepad.exe %s'

ZopeEDIT will open Notepad for you. When done, you save and close notepad. ZopeEDIT will ask you wether or not you want to save the file to Zope. Click 'Yes', and your changes are now on your Zope server.

Subject: [Zope] dtml-let and MySQL
In-Reply-To: <20000320100802.14614.qmail@web4001.mail.yahoo.com>
Message-ID: <4.2.0.58.20000320162316.00ca5100@195.60.12.162>

As I understand it any variables you set in <dtml-let> </dtml_let> blocks 
are local to that block of code. There's no way to 'pass' them to an SQL 
Method. SQL Methods only use values which have been set within the REQUEST 
variable. The REQUEST variable is where Form variables are held - but Form 
variables only exist until the next Form is called. You can however 
explicitly force values into REQUEST using the syntax

<dtml-call expr="REQUEST.set('yourvariable','yourvalue')">

and these would then be available to an SQL Method.

A tip which I found very useful when working with the REQUEST variable and 
forms is to put the following line into your code
<dtml-var REQUEST>.

This displays all the current values within the REQUEST variable.

There's also a useful How-To on Namespaces which gives more background on 
this area (search for Namespace in www.zope.org).

However IMHO its an area of Zope that needs a lot more documentation and 
tutorials because I don't think it's very intuitive.

I also think it would be nice to have a version of SQL method which allowed 
you to pass the values you want into it - it's beyond me at the moment though.

Good luck

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985DC@pces.cadlab.it>

[Absolute beginner's question...]

I'm thinking to use Zope for an Internet site I have to develop for an
internal client. They will just receive a PC Box from me and will know
nothing about the technology in it.

I wonder if I can safely allow them to drop HTML documents inside Zope. This
would allow to publish their own simple HTML documents without worring about
DTML and the like (I do not think they are interested in developing their
own DTML-enabled sites...).

Is it Zope able to handle plain HTML+CSS+JavaScript documents, without
having to use any DTML file?

Can the user just drop a HTML document in a server directory and have this
document published on the intranet? How can I determine the directory they
can use?

Thanks.

I saw a nearly identical traceback, as well.  You might have to:
        1. play with the imap settings (probably need to change the
           LS* variable in IMAPHACK.py, can't recall it's exact name)
        2. make sure you are running 1.0.4 (a fairly recent version).

Sure.  Although with a little work you can have it automatically get your
intranet's headers and footers, for example.  But just plunking it in works
just fine.

Give them a user that only has permission to access a certain folder.  Then
set up ftp for them and they'll never know it's Zope.

Not exactly, but close enough.  A DTML Document could certainly
contain just HTML code and no DTML, and Zope would happily return
it and the client would render it just as if (say) Apache had
returned it.  I presume you could use the ftp server built in to
Zserver to upload the documents to whatever folders you had given
them permission on.  But keep in mind that all the Zope data is
stored in the ZODB (a single file in the unix filesystem) not as
seperate files in that filesystem, so any update transactions need
to go through Zserver somehow or another in order to update the content.

You might want to consider teaching them the (pretty easy) management
interface, though, as they could use that to upload files directly
from their PC desktops using just their web browser.  Who knows,
they might even decide they want to start taking advantage of Zope's
content management features, and actually start learning DTML <grin>.

Zopists,

Are there any other quoting methods besides html_quote and url_quote?  I
am looking for something that turns periods and minus signs to an
alternative as well.  I guess I could roll my own external method, but
I'd rather not if there are more to choose from.

All my best,

Doh**2. That now works very nicely. Thanks. One last request:

Any way of suppressing the reflection of the password in the
dialogue box that pops up? That would make my Computing Service
colleagues alot more comfortable.

Message-ID: <Pine.OSF.4.02.10003201131530.4100-100000@batman.tamucc.edu>

Currently, I have a customized standard html header, and would like to be
able to use the same header for all files, but have different titles for
each...I have tried using this in my header:

<title><dtml-let var="'TITLE'"></dtml-let></title>

and then using this in the individual file:

<dtml-let var="'TITLE'" 
value="'My title'"">
</dtml-let>

I only use the "'....'"...becuase otherwise, I get syntax
errors.....however, when I look at the source code on the page, it reads
<title></title>...so apparently this is not working.  Any suggestions?

Thanks,
Jessica Tishmack

This is the second report of this bug but I cannot reproduce this, can

You can't.  As security policy, we do not write code that lets Zope open
files outside of the Zope directory.  You can, of course, do this in
your own code, but we do not recommend it.  My first version of
etcUserFolder actually was able to open files anywhere (hence the name)
but I was enlightened by Jim that this is a possible secuirty hazzard.

There error occours because there are pickles in your database that
cannot be loaded.  The 'persistent' information for an object in the
database is a 'pickle', or a serialized representation of the object. 
In order for the object be loaded into memory the pickle needs to be
unwound into an object in memory.

However, this serialized representation does *not* contain any active
code, it's just the state of the object.  In order for the object to
truely 'come to life' the pickle must be matched up with the python code
that all objects have in one way or another.

This error occours when the pickle can be read, but no coresponding
python code could be matched up with the object to bring it to life, or,
an error occoured while object was being unpickled.  Unfortunatly, there
aren't any better iagnostic tools to find why these pickles cannot be
unloaded, and for the most part they are now orphaned objects, you
cannot delete them or manage them or remove them from your database.

I can envision some kind of tool like fsck or scandisk that goes through
your database (probably offline) and lets you examine/purge/fix these
kinds of dead objects.  Ty Sarna has come up with an introspectio ntool
called the Tranalyser that would probably be a good place to start.

from DateTime import DateTime

Now you can instantiate DateTime objects like so:

DateTime(string)

and compare them easily:

if date1 < date2:
  print 'foo'

Hi,

I just wanted to let you know that this has been fixed in the zope 2.1.4-3
package; never, never, never release a package without having it installed
yourself once, I know ;-)

Thanks for the report,

Subject: [Zope] retrieving variables from an earlier form
Message-ID: <Pine.LNX.4.10.10003201247220.564-100000@lawlearn.wuacc.edu>

I'm trying to create several screens to allow my technician to keep a log
of problem reports.

I chose to create a search form.  The data will display in the usual table
form and the user will select the item wanted for display in an update
form with the values shown as default field values.

In the table view, I created a link to my next form in the following way:

<a
href="http://localhost:8080/School/Admin/Computer/displayitem?id=<dtml-var
id>&Submit=Submit&Query">

The problem is that no data gets stuffed into the values="" attributes of
the form which leads me to believe that either I'm not using the
<dtml-sqlvar> tags correctly or I'm not calling the data selected from the
database (mysql) for use in the new form correctly.

I read the how-to on inserting sql data, but I want to create a form that
will update existing records.

Any help will be appreciated,
Joe

Thanks.  One problem that arises when I do this, is that in my
webpage, when I do  "view source" I have ...


stuff
<title></title>           ---> From the standard_html_header file
stuff

<title>mytitle</title>    ---> From the file itself

I guess I am wanting to know how to tell the header to place the correct
title in its own <title></title> portion, and not to add a second
<title></title> line.

Thanks,
Jessica

Subject: [Zope] ExtensionClass
Message-ID: <FRQFOV$I2ZLh74u5vUUBGyDxD3ExLIi5oGV5zoaH@uol.com.ar>

Hi!

I have an ExtensionClass(es) question and, being the 
latest releases of them distributed with Zope, I 
decided to ask it here.

Situation:

1) Class A subclasses 2+ extension classes E = 
{E1,...,En} and perhaps another non extension classes C 
= {C1,...,Cm}. That is, class A(B1,...,Bk): ...., where 
B1,...,Bk are each in E or in C.
2) a is an instance of A (a = A())
3) a.foo(bar) is invoked
4) getattr is invoked in the first extension class in 
the inherited classes list (i.e. the first Bi belonging 
to E)

Question:

What happens then?
I guess that calling Py_FindMethod (inside getattr 
implementation) will trigger a search in instance and 
base classes' dictionaries, but what about the other 
extension base classes and what about the searching 
order?
I can't find any doc on these, so I'm needing your help.

Thank you, Carlos.

(Snip.)

This is due to a fix in Acquisition to a bug that obscured a bug
in the handling of inner ZClasses. Sigh.

We'll be putting ot a release to fix this. In the mean time, if you wish
you can edit lib/python/App/Factory.py and change the line:

    _setObject=Acquisition.Acquired

to:

    _setObject=_getOb=Acquisition.Acquired

You are exactly right!  I took out the title lines in the file, and just
kept the title line in the header, and gave my file a title...and voila!

Yes.

Actually, there is a buglet in XMLDocument that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

In 2.1.5, when you add an XML document, you get a
WrongDocumentException.  This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py.

There may be other problems, however, I'm not very familiar 
with XMLDocument and wouldn't be a good person to find them.

Perhaps you could apply this patch and see if you can find 
anything else wrong.  If you do, please provide me and Amos 
with some sample data and instructions for reproducing the problem.

It did work.  The filename that appears in the traceback is the name
of the .py file when it was compiled to produce a .pyc file.
Since you copied the pyc file, the old name was retained.

Please see my other note for information on a fix to this problem.

It looks like you are trying to use an anchor tag to submit a form. 
This will not work as it is not proper HTML.  You need to use an <input
type=submit...> or some other valid way of submiting the form.

Hi,

sofar I solved the creation process of user accounts. This was quite easy
after I read the code for this. But now I have problems adding new roles via a
specialized interface. I setup tghe REQUEST object correctly, then I call
manage_defined_roles and I get various errors. Is their any method at all to
create Roles besides the management interface of Zope or via External Methods?
Setting local roles is easy, but I can get the role added to the system at
all. Any help appreciated. Thanks a lot.

After reading the how-to that Kevin Dangoor and making some changes from
the management interface, I am able to edit values connected to my Zope
objects. While this is a start, it really isn't ideal. As Nick Henderson
suggested, it would be better if there was a way to do this from standard
DTHML, so that the editing form looks like a filled-in entry form? Does
anyone have any suggestions? Also, a number of the fields in my entries
are coming from "select" lists or checkboxes. This is being done to
control the vocabulary so everyone enters the same term for the same item
(eg. It would be a problem for my application if person #1 calls it "Time"
and person #2 calls it "Time Magazine." Does anyone know of a way to take
the existing values of an entry and pull it into a select list and tell
the list to keep them "selected," or have an idea of a direction to go
in order to attempt this?

There's actually three parts to every error, the error type and
description, and the traceback.  Could you also send the error
description (it's above the traceback) so that I can look at the code
and they to see  what is raising the TypeError (which is the error
type).

What kind of errors?

You should be able to call a method that adds roles just like the
managment interface does.  Have you checked out
lib/python/AccessControl/access.dtml?  At the bottom is a second form
that lets you add roles.

Michel,

I'm trying to use a link on the Report Form to call another form that
displays the single database record with each field filling in the new 
form.  If the user is the proper authenticated user, an update button will
be available, anonymous will only get a listing of the record.

Granted, I'm not doing it the right way. Perhaps my question is how do you
select a value, in this case the record number, and use that value as a
key to pass the entire record to the form for display.  My calling DTML
Method is listed below.

So the question is how can I call up my new form with my selection
appearing as data.

Thanks,
Joe

Message-ID: <4.2.0.58.20000320194209.01654a20@192.168.0.2>

Hello,


I got a similar error with Zope 2.1.5 on Win32 Saturday. Here's how:

- I created a ZClass, TestClassA (it subclassed ObjectManager).
- In TestClassA, I created another ZClass, TestClassB (it also subclassed 
ObjectManager).

So I got ControlPanel / Products / AProduct / TestClassA / TestClassB.

Then :
- I created a TestClassA instance somewhere.
- In this instance, I tried to create a TestClassB instance.

I got:
Error Type: AttributeError
Error Value: _getOb

Somehow this was related to RESPONSE. This error didn't occur when for 
testing I added ", RESPONSE" to the line

   <dtml-with "TestClassB.createInObjectManager(REQUEST['id'], REQUEST)">

in the "TestClassB_add" constructor method.


Cheers.

Alexandre

I'd really like to see a global method that replicates the property sheet
editor but is callable from code rather than the management interface
and can thus be "wrapped"...

There is some sample code somewhere that shows how to mostly do
this in DTML.  I looked at it, but wound up just creating my own
specific editing form anyway, because I couldn't get it to run
out of the box and didn't have time (or at that point the knowledge)
to debug it.

Here's a snippet of code from my custom edit form that does this for
a multiple select property I have.  Hopefully this will help you roll
your own.  'regions' is a lines property defined on another propertysheet
(named 'constants' <wry grin>).  I haven't yet figured out how
to call this variable so I can use it in the addForm.)  I basically
copied this out of that sample code I mentioned above.

  <tr>
    <th><label id=in_regions>In Regions</label></th>
    <td>
      <select name="in_regions:list" multiple size="7">
        <dtml-in regions>
          <option <dtml-if
            "_['sequence-item'] in in_regions">SELECTED</dtml-if
          >> <dtml-var sequence-item></option>
        </dtml-in>
      </select>
    </td>
  </tr>

also,

how can i access directly objects atributes without using <dtml-in

Actually, i need to access to sequences at the same time. That's not

Please send email directly to me cause' i'm not suscribed.

The '%s' gets replaced by a temporary file name, it definitly needs to
be there. I know nothing about notepad.exe, but it sounds like notepad
can't accept filename arguments on the command line. I can't verify this
however. I know people are using ZopeEDIT in Win?? so it must be
something with notepad.

Hi Curtis -

We are going to be releasing a fixed update today - in 
the meantime, if you could try something out to verify 
that it fixes your problem as well, that would be great.

I've attached a file ZRDB.tgz. If you copy that to your
lib/python/Shared/DC/ZRDB directory and unpack it, then 
restart Zope you should be working again. If you have a 
minute to try this can you let me know how it goes? 

Thanks!

Suppose that Bi belongs to E (following the previous 
names) and is not, for example, Persistent, and that Bj 
is Persistent (where j > i).
The problem of the getattr (I mean in Persistent) 
invoked only when the attribute being accessed doesn't 
belong to the instance dictionary or class dictionary 
is still here, isn't it?

Subject: [Zope] my zope has got no pid!
Message-ID: <000a01bf92a4$f172fd00$1cf108c3@SteffenLemke>

Hello there,

something's strange with my zope. I am running zope as my personal zope-user (at least I have started it this way) but I don't get any pid if I say "ps -a". And I cannot stop the server because the script tells me kill: xxxx - no such pid? What's wrong with it?? Is there any additional flag I have to set or unset in the standard-scripts? 

Thank you for your help,
Steffen

Ok this problem is due to the bug in 2.1.5 that also breaks ZSQL
Methods, it is unlrelated to ODBC.  We will be releasing a 2.1.6 that
fixes the problems in 2.1.5 including this one.

try 'ps aux' (on linux at least).  Any other platform, who knows.

I don't know.

No, but certainly your Zope is running with a PID, it must be.  Go to
the control panel, you should absolutly get the right pid there.

Here is what I did to get it going...

EDITOR_CMD = ' "notepad" %s' 

# I put a space in there just to make it easy to see for the email but by
quoting notepad the command line gets interpreted properly.

Subject: [Zope] [ANNOUNCE] Zope 2.1.6 released...
Message-ID: <613145F79272D211914B0020AFF6401914DE8B@gandalf.digicool.com>

Hi all,

Zope 2.1.6 has been released - you can download it from
Zope.org:

http://www.zope.org/Products/Zope/2.1.6/


This release fixes a few issues with Friday's 2.1.5 security
update release:

  o Some bits from the currently development branch got into
    the 2.1.x release branch, causing problems for folks using 
    certain database adapters - this has been fixed.

  o A fix to Acquisition that happened in 2.1.5 caused a problem
    with ZClasses, since some of the code in Factory.py previously
    worked around the problem and now no longer needed to. This has
    been fixed in 2.1.6.

Users of the SiteAccess product should note that the security 
changes in 2.1.5 necessarily require a change to the SiteAccess
product - as he noted in a previous email to the zope list, Evan 
will be releasing an updated SiteAccess shortly.

Also, the XMLDocument product has a buglet that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

Currently, when you add an XML document, you will get a
WrongDocumentException. This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py. A new 
rev of XMLDocument containing this fix will be available soon.

Note that we have also posted "diff" updates as .tgz files 
that will let you easily upgrade an existing 2.1.x site. 
These updates are available for those currently using the 
2.1.x source release or the 2.1.x binary releases for either 
solaris or linux.

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

In an NT cmd.exe shell:

  ...2>C:\temp\zope.err >C:\temp\zope.log

or:

  ...2>&1 >C:\temp\zope.log

should both work.  On Win95/98, I think you're sunk -- the COMMAND.COM shell is
too brain-dead.  You might try 4DOS or another replacement shell.

"Broken pipe" says that the peer process/thread on the other end of a pipe died
without shutting down the pipe cleanly.  You should be concerned, because these
are your "Zope" threads that are dying -- eventually, you will have none left to
service requests.

This problem is a symptom of something inside Zope which is killing off threads,
most likely an unhandled exception somewhere.  Try turning on the
STUPID_DEBUGGER_LOG and see if you get more enlightening log output.

Hi,

well I use the following code snippet in my factory method of the product I am
developing.

<dtml-with "manage_clone(Home, REQUEST['new_id'], REQUEST)">
        <dtml-call "manage_changeProperties(
                        company_name=REQUEST['new_company_name'],
                        title='OS Job Tracking System für ' + REQUEST['new_company_name']
                    )">
        <dtml-call "acl_users.manage_users(submit='Add Role', REQUEST=REQUEST)">
        <dtml-call "manage_defined_roles(submit='Add Role', REQUEST=REQUEST)">
    </dtml-with>

I set the role element of my REQUEST object to a string, which is the name of
the new role. When I look a manage_defined_roles in
lib/python/AccessControl/Roles.py it searches for a submit element in the
REQUEST object that has a certain value. Otherwise it calls manage_access. 

Well, I set submit to the required value, so that _addRole is called. Then I
get the error

    Error Type: AttributeError
    Error Value: aq_acquire

And when I call it without setting the parameters at all

    Error Type: KeyError
    Error Value: SCRIPT_NAME

When I call it with REQUEST=REQUEST I get the first error again.

Any idea what is wrong with my call? I am not using any external method or so
from product, but I develop the product in Zope and use only DTML scripting,
cause this is sufficient for my task.

I am running Zope 2.1.4 as a standalon zserver. May be this helps too.

Any hint would be really fine.

Best regards,

    Oliver Andrich

Hi,

I just discovered something strange. At least I think that it is strange. I
can assign users Roles that don't exist at all in the system. In my last Email
I tried to create a Role in a system wide context. Well, know I removed the
role add code and just added the user with a fantasy role. Now the management
screen can't handle the user anymore cause the role doesn't exist. But when I
do a acl_users.getUser('admin').getRoles() I get the fantasy role I
    specified. Ok, this is not the solution, but should the manage_user code
    check if the role that is specified exists at all?

Bye, Oliver

start.bat is all you need.  It will leave a dos-box open, but that's fine.  It
will show you some (occasionally) useful output from Zope.

Steffen

This happens when you rename the Zope directory after installation.

The stop script has a hardcoded directory in it.

If you edit the stop script and change the old directory name to the new one
all works as expected.

Vladimir,

I just had this same thing happen, and bypassing the factory worked.
I changed the calling method from calling "maClass_factory to
myClass_addForm, and the add method worked fine.  That seems very buggy
to me.

The traceback was posted onthe zope-dev list this morning.

Here it is anyway:

<dtml-with "WorkDayClass.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-call "propertysheets.WorkDay_properties.manage_changeProperties(
             work_date=REQUEST['date'],
             )">
 <dtml-call reindex_object>
<dtml-with>

Now I get:

Error Type: AttributeError
            Error Value: _getOb

Subject: [Zope] Sybase: How generate id keys? (surrogate keys)
Message-ID: <20000320232355.87383.qmail@hotmail.com>

Hi,

How do people generate id keys (surrogate primary keys)
in Sybase+Zope? There are some recommended ways of doing it
in Sybase with stored procedures but I can't run stored
procedures in Sybase.

I am looking at heavy-traffic strategies. So I need something
slightly better than a simple increment table for the keys.

Any recommendations? Thanks in advance.

D'oh!  The environment variable which Zope checks for is STUPID_LOG_FILE:

 * If it is set to a blank string, Zope writes the verbose logging
   to stderr;

 * If it is a non-blank string, Zope opens it as a file and writes the
   verbose logging there;

 * Otherwise, Zope suppresses the verbose logging.

Ayup, there have been several threads reporting such restarts lately -- have you
been following them? (some were on the zope-dev list, I think).

Just to add my two cents:  I've seen these as well, usually connected to
someone disconnecting from downloading a page mid-way, usually also
connected to zope going into a really tight 'select (0,1), select (0,1,2),
select (0,1,2,3), select(0,1,2,3,4), etc loop - until it runs out of fd's
it's allowed to open, crashes, and needs restarting.  Oh, and only when
running with FastCGI.

Redhat 6.1ish, glibc from rpm glibc-2.1.2-15, python 1.5.2 from rpm
python-1.5.2-7, apache from rpm apache-1.3.9-8.

My response so far has been to whack a while : ; do ... done loop around
the kickoff command in ./start, and run the whole lot under screen -dmS.
STUPID_LOG_FILE didn't produce anything that was immediately useful to me
:(

I've just upgraded to 2.1.6, and so far I haven't seen the problem, which
may or may not be a good sign ;)

"Manage properties" is allowed only by those in the "Manager" role. In
order to allow all authenticated users to use
the "manage_changeProperties" method in "CategoryCustomizationForm", I
assigned the proxy role of "Manager" to "CategoryCustomizationForm".
However, zope still only allows users in the role of Manager to access
"manage_changeProperties" in my form. In other words, the proxy role
assigned to the method "CategoryCustomizationForm" failed to override
the permissions of its containing folder /News. As a temporary fix, I
gave the "Authenticated" role permission to "Manage properties" in
/News. This works with regards to allowing all authenticated users to
access "manage_changeProperties" in my form. However, in the long run, I
don't want all authenticated users having manager type access to all
properties of /News. I have this failure of proxy roles in other areas
of development too, such as dtml creation of folders via manage_clone.
Is there something I'm missing about how to use proxy roles? Thanks for
your time.

Unfortunately the IDENTITY column is not a good option.

According to our local Sybase expert, The IDENTITY columns
are just too buggy to use, even after the newer releases of
Sybase. They cause too many troubles, that is why we are
looking at alternatives. In older versions of Sybase, the
problems were so severe that they would cause the database
server to crash. Some drawbacks that were mentioned:
(some are fixed, but these are not the only problems...)

(1) When database server crashes, apparently the IDENTITY
    column jumps to the next block of values, so the table
    index space become sparsely populated, and you may hit
    the roll-over situation earlier than expected.

(2) When using BCP utility to download and upload tables,
    there are some problems with the IDENTITY columns, too.

(3) It is hard to access the values of the IDENTITY column
    when you are in multiple SQL statements.

Anyway, there seem to be too many problems, so the IDENTITY
column approach has been discarded. :(

Hung Jung

I've released LocalFS v0.1.7. It hasn't been tested extensively so I've left the
bits for v0.1.6 up on the site. I'm just too excited to wait. :)

The url is: http://www.zope.org/Members/jfarr/Products/LocalFS

Enhancements in v0.1.7:

- Added the ability to customize mappings between file extension, content-type,
and Zope object class.
- Added the ability to customize content-type to icon mappings.
- LocalFS objects now work with the <dtml-tree> tag, so they can be traversed
using the navigation menu.

(plus a few bug fixes)

If you try it out please let me know what you think or if you find any problems.

Thanks,

Subject: [Zope] ZClasses and clone/delete methods
Message-ID: <14550.61379.392791.186258@antares.int.plain.co.nz>

I need to know whether I can set up clone and delete methods in a
Zclass that automatically get invoked any time someone deletes or
copies an instance of that class from the management interface (via
cut and paste or whatever). 

What I'm doing is creating a simple link class that just stores the
key to a RDBMS row that contains all the details of the link
(description, URL, clickthrus etc). The trouble is that when a link is 
deleted from Zope, it needs to touch the db record or that record will 
become orphaned - ideally the db record needs to keep a reference
count of the number of link objects out their, and they need to
increment or decrement that count as they get copied and deleted.

So can this be done with a ZClass (if not, why not :-)) and if it
can't, how can I do this with a Python Product (given that I've never
written one!).

TIA,
John.

Message-ID: <38D6F845.A010DBE2@suprize.com>

Hi,

    I have Zope 2.1.5 and Oracle 8.0.5 running on the same Linux box.
ZOracleDA was installed successfully and bridged Zope and Oracle.
I can call my stored procedure by creating Z SQL Method like:

    begin
    procName(arg1, arg2,...);
    end;

But I cannot get return arguments (OUT args) no matter how the Z SQL
Method is set. I have tried the interfaces mentioned in DCOracle
documents, but failed. The only work-around I've found is creating 
extenal methods and import DCOracle via python. Is there any way
to get the OUT arguments from Z SQL Method? Thanks a lot!

Message-ID: <1F176F2C2977D311B3300090270E637887B105@scl-exch.phoenix.com>

I've read
http://www.zope.org/Members/Zen/howto/FormVariableTypes
and a few other HOW-TO's and still haven't figured out
how to make use of the :record type in form variables.

My form looks like:
<form method="post" action="processForm">
<input type=text name=choice.1:record>
<input type=text name=choice.3:record>
<input type=text name=choice.10:record>
<input type=submit>
</form>

Now processForm need to tell which and how many choice.x:record are entered.
This works:
	<dtml-var "REQUEST['choice']">
that's as far as I can go. I want to do:
	<dtml-in "REQUEST['choice'].keys()">
		<dtml-var sequence-item>:<dtml-var sequence-value>
	</dtml>
but it doesn't know what "keys()" is.

Question: how do I get the keys and values for this "choice" record in
processForm?

Thanx,
-Tanming Fong

iI'm going to have to disappoint you.

- I never published the object, it was simple and not that general. Also, I cannot release it now, because it was written while working for my previous employer.

- The site for which I used it was for a big Dutch youth event, and now that it has taken place the site has been taken down again.

Record objects do not implement a mapping interface.  Form elements are
turned into attributes of your 'choice' object, so your objects has
instance attributes named 1, 3, and 10.  You will need to use
_.getattr() to access these attributes since numbers are not very good
attribute names.

It might be a good idea to look into a new ZPublisher type called
:dictionary (or :mapping) that works much like :record, it would be
fairly trivial to implement, want to take a stab at it?

Message-ID: <38D73050.8A2546B8@knoll-is.de>

Hello Zopers,

I just joined these mailing lists. I have a boring problem I can't
understand. I wrote this little program:

import Persistence
import ZODB
import ZODB.Transaction
import ZODB.FileStorage

class dbclass(Persistence.Persistent):
	def __init__(self):
		self.thedata = 'testdata'

def getdata( request=None ):
	name = 'somename'
	db = ZODB.DB(ZODB.FileStorage.FileStorage('myfile.fs'))
	connection = db.open()
	root = connection.root()
	if not root.has_key( name ):
		print "initialising"
		root[name] = dbclass()
		get_transaction().commit()
	r = root[name].thedata
	connection.close()
	return r


This program works very well if it is started directly using the python
interpreter. But if I call it from Zope using 'Try it' in the management
console it works only one time. The second call of the function results
in:

Zope Error

          Zope has encountered an error while publishing this resource.

under Win98. I have a couple of different Zope instances running on Linux and
Windows, but that was the first data loss. It seemed to me as if the session
had been running in "demo" mode so that changes would not be really persistent.
As in Alexandre's case, I first thought I was dreaming because there was no
hint of my data except for the log files.

I suggest some further investigation into that. If Zope really lost things that
easily, I'd consider not using ZODB for production sites ...

BTW: In my case it also was a Windows system crash that caused the data loss.

This sounds like Win98 is using a write-cache that didn't get flushed to disk
because of the crah. IIRC, Zope forces write cache flushes, but it could well
be that Win98, being a client-patform, ignores that for performance reasons.

Then again, who'd use Win98 for production sites?

Try %1, instead.  %1, %2 etc stand for a commands first, second

*Sigh* Did anyone read my reply to the original message?? A backslash has
special meaning in python! And positional parameters have nothing to do with
python either!

In python (as in many programming languages based on C) \n means newline. Just
fire up a python interpreter:

  >> repr('C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\012otepad.exe %s'

\012 is the octal representation for newline. Note that, as \W and \s are
meaningless, they are interpreted as if you used a double backslash.

The solution immediatly becomes clear:

  >> repr('C:\\WINNT\\system32\\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'
  >> repr(r'C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'

ZopeEDIT uses the string to build up a command to feed to the system. It uses
the default python % operator to replace the %s (which is a C-sprintf-like
string formatting code) with the filename of the temporary file it creates.

Please, next time, use the python debugger or something to see what goes
wrong. Paul has long since gotten ZopeEDIT to work, BTW.

Subject: [Zope] Weird ZSQL Method thing...
Message-ID: <38D760E4.F25D1D00@nipltd.com>

Hi,

This is weird, I've got a solution but I don't know why I need to use it...

I have a DTML Document that uses two ZSQL Methods, something like:
<dtml-in item>
  ...the item ZSQL method returns cid...
 <dtml-var cid>
 <dtml-in case>
    ...the case ZSQL method takes cid as a required parameter
 </dtml-in>
</dtml-in>

Now, using this returns an error: Bad Request: [cid] 
which I've grown accustomed to seeing when a requried parameter is missing.
However, if I dtml-comment out the second dtml-in, it works fine and the correct cid is displayed by
the dtml-var.

The only way I can get it to work is to make the second dtml-in look like:
 <dtml-in case(cid=cid)>

I really don't understand why I need to do this and why the 'case' ZSQL method doesn't just pick up
cid from the current namespace...

Any ideas?

Chris

Um, more or less (apart from the quotes). The ZSQL Methods use namespace
different from than normal DTML documents/methods (though I don't
exactly know how). Therefore you have to call them explicitly with an
argument.

If this is true, it's really counterintuitive and should be changed if at all possible.

If it's specific to ZSQL methods or in otherwise confusing situations, then there's even more reason
to change it...

Anyone got any comments/suggestions?

Message-ID: <v04220807b4fd1bb332c0@[128.240.198.13]>

Hi all,
Anyone got any experience with FSSession and external methods 
(actually a PythonMethod).

I want to get the data out of an FSSession object using this construct-type

<argument>self</argument>

FS = self.FSSession
out = ""
for k,v in FS.items():
     out = out + "K:%s, V:%s<br>" % (k,v)
return out

and get this;

<!--
  Error type:  AttributeError
  Error value: _v_data
  -->

Looking at FSSession.py, _v_data is there as part of the FSSession class;
     def items(self): return self._v_data.items()
but it's not getting through to the method.

Anyone got a fixe for this? I need to do some heavy processing with 
the contents of the FSSession object so I can't *really* use DTML.

TIA
tone.

have you given roles to the user???
to protect the folder, I suppose you have created a role 'ROLE', and said
that anyone but those with the role 'ROLE' are able to view the folder.
however, if the users in the NT User Folder are not given roles, there are
two case:

when you create a NT user folder, you have to choose whether default
behavior when a user is not given roles is to acquire user settings from
higher user folders or not.

- if default behavior is to acquire settings, due to the very nature of user
folders, NT User Folders says the user *does not* exists if no roles are
defined, to allow higher user folders to handle the user. this is the
default for a nt user folder created in a sub folder

- if default behavior is not to acquire settings, NT User Folder always says
'yes' when the user is asked, but if no roles are defined, the user is
assumed to have to anonymous role. this is the default for a nt user folder
created at the top level

if roles are created for a user, it always exists, what ever the default
behavior is.

back to your problem: if you choose not to acquire user roles, all users for
which you didn't give roles are *anonymous*, so they have no rights on your
protected folder.

This is not true.

Method A:

<dtml-with "_(bob='uncle')">
  <dtml-var B>
</dtml-with>

Method B:

<dtml-var bob>

_will_ print 'uncle'.

It is specific to ZSQL Methods, they create their own fresh namespace. 
There may be a good reason, I can't think of one.

ZSQL Methods create their own namespace (I don't know why).  You must
explicitly pass them arguments.  You can, of course, pass then entire
namespace:

<dtml-in "case(ns=_)">
  ...
</dtml-in>


and in your SQL Method:

<dtml-with ns>
 ...
</dtml-with>

This is, like all of my advice, completely untested and off the top of
my head, but it should fly.

We have deployed a heavily modified Squishdot site that handles around

Now but we will have to. After 3000-4000 postings Squishdot is very slow
and I suppose zdiscussions too.

An external method will be appropriate. Forget DTL for such task.

IMHO, this isn't true. I have several ZSQL methods which have named parameters. 
It appears that they can get these parameters from REQUEST and possibly (I can't remember and
haven't got time to check :( ) things like dtml-let and dtml-with without having to explicitly pass
them which is why I was so surprised that dtml-in didn't work as expected.

Can anyone who knows say why this is the case and exactly what the critera are for something being
'visible' to a ZSQL method's parameter list?

HSCH,

Chris

You need to call FSSession before you can use it, as in DTML otherwise the
data will not be loaded into _v_data. I have just tried the following and
it works:


FS=self.FSSession
FS()
out=""
for k,v in FS.items():
   out = out + "K:%s, V:%s<br>" % (k,v)

Martijn, you're right. Nobody would use Win98 on production systems. But quite a
few people use it on their notebooks or home PCs for development, I guess. At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Well, I don't think that is the optimum solution, especially for big sites. 
Even though that is the Zope way of doing things, I hate the idea that I 
clutter my ZODB with files. I would suggest you add a property called 
attachments to your Class which points to various URLs and then serve the 
files via Apache. You may want to use PCGI to do this.
We just switched to PCGI and now we serve Images and Documents from another 
port via Apache (we can also use SSL now). That helps to keep the I/O 
stream to the ZODB file moderate. Remember, ZODB is just big one file (even 
though Zope does a lot of caching). You could also check into LocalFS, 
which is nice in some cases (even though we were unsuccessful to upload 
files, using it.)

Stephan

Subject: [Zope] Modifying Standard Error Pages
Message-ID: <Pine.LNX.3.96.1000321140832.11696D-100000@marvin.nipltd.com>

I'm currently trying to modify Zope's standard error pages in order to
have errors (such as 404 not founds or DTML errors) e-mailed to the 
webmaster as they occur.

At first, I thought this would be as simple as modifying the
standard_error_message document found in the root of the Zope
installation, but it appears that changes to the file do not get displayed
(even after forced refreshes) and thus it doesn't seem to be in use.

A search on zope.org lead me to find the real error message embedded in
<zopedir>/lib/python/OFS/Application.py - I've modified this and it
appears to work, but doesn't support HTTP related errors such as 404s.

After a bit of a search, I've tracked down HTTP-related error reports to
<zopedir>/lib/python/ZPublisher/HTTPResponse.py but, while this can be
modified, it doesn't support DTML as the HTML error message is returned
without apparently being parsed by Zope. As a result, I can't have
dtml-sendmail send an error message report.

Okay, I could modify HTTPResponse.py to send a mail using something like
Python's smtplib, but before I do that, have I overlooked the obvious and
is there really a much cleaner, easier way to modify the error pages
without delving into the sources?

Thanks in advance!

Neither. Add orphan=0 to the tag, and you'll feel sane again.

if ommitted, orphan is set to 3. This means that if the last batch is smaller
than 3 items, that batch is added to the one but last batch. See it as a
'minimal batch size' parameter.

When you call a method 'by name' (<dtml-var methodName>) then the DTML
machinery will magically try and line up any arguments to that method
with any names in the namespace.  It will do this for any kind of method
that accepts arguments, DTML Methods, SQL Method, ext methods,
PythonMethods, and methods written in python of the object this()
etc...  _However_ if that method is a SQL Method then as soon as you
enter the method any reference to <dtml-var name> in the SQL method will
NOT find the name in the previous DTML namespace.  If you want a name in
the DTML namespace to match an argument, that's a different matter all
together, and it will work, if you want to <dtml-var name> in a SQL
Method and 'name' is in the namespace of a calling DTML method, then it
won't work.

Have a look at:

  http://www.zope.org/standard_error_message/view_source

and you'll see how the Zope.org site handles 404 Not Found.

In the current CVS they do.  Tanming, if you're using a source code
distribution of Zope you can change the definition of class 'record' in
ZPublisher/HTTPRequest.py to the following:

class record:
    def __getattr__(self, key, default=None):
        if key in ('get', 'keys', 'items', 'values', 'copy', 'has_key'):
            return getattr(self.__dict__, key)
        raise AttributeError, key

    def __getitem__(self, key):
        return self.__dict__[key]

    def __str__(self):
        L1 = self.__dict__.items()
        L1.sort()
        return join(map(lambda item: "%s: %s" %item, L1), ", ")

    __repr__ = __str__

Cheers,

Evan @ digicool & 4-am

Are these batches of records the 'last' batch in the ZSQL query?
If so, it's the 'orphan' parameter kicking in, which *I believe* is set to 3.

If you have 19 records returned with a batch of 4, you get
1-4, 5-8,9-12,13-16,17-19 - no problem there

If you have 9 records returned with a batch of 4, you *would get*
1-4, 5-8, 9 (on it's own).

The 'orphan' parameter would make the last batch return 5-9 (ie 5 records).

It's described in greater detail in the ZSQL users guide...

Neither.  The in tag by default does not like orphans (result batches
smaller than 'size').  Set 'orphan=0' and sleep in peace that your
sanity is intact (and that the in tag is bug free).

Here's something that worked for me, it's got extraneous imports and 
stuff ('cos it's the front end of something bigger), but it does 
work. I add nnn_ to the beginning of file names so I can have more 
than one file called 'test.doc' in the directory, and I've not 
finished the URL stuff yet, but it certainly uploads normal files to 
LocalFS (probably because it bypasses the LocalFS machinery all 
together ? :) .

add_details is a ZSQL method that adds info about the upload into a database.

Martijn,

I think the problem is that any changes made to standard_error_message don't appear to have any
effect. I've tried just simply changing the text, add ' - wibble' after 'Zope Error' and the old
error message is still displayed, even after restarting Zope...

What's going on?

Is there some method such like with SiteAccess that you have to 'set' a DTML method as the standard
error message or is something else causing the old error message to be displayed?

HYCH,

Chris

For example if you order a product it should be saved somewhere over a

Same like Amazon.com or something like this.

Maybe someone have a simple solution for this.

I have no idea. I don't use SiteAccess, so I don't know what influence it has
on this issue. I can change standard_error_message just fine here. Try and
understand what the default code does first, then try and make a few
educated-guess changes to that code.

Does anything show up in the undo log? After a change, does the edit window
have a message 'Content changed [Date]' just below the tabs?

You've seen this before?  Great you're the first person who actually
gives me hope I'm not insane.  We have been running 7 sites from a
single zope install replicated across 3 servers.  Two of the servers
experience frequent Zope restarts (as often as every hour).  The third
server running an older version of Redhat (6.0 I believe) and
glibc-2.0.7-29, and hardly ever restarts.  

We are running Redhat 6.1, glibc from rpm glibc-2.1.1.6, python from rpm
python-1.5.2-7 and Apache/1.3.9 mod_fastcgi/2.2.3 and Apache/1.3.11
mod_fastcgi/2.2.3.

We have even gone as far as to modify FCGIServer.py to produce "debug"
output  to determine which requests go unanswered at the point of
restart; hoping this would lead to some suspect DTML or ExternalMethod
code.  No luck.

We're waiting a bit to upgrade to see how it shakes out w/ SiteAccess
etc.

We've also recently bumped cache *WAY* up, 450,000 items, w/ 5 minute
target max between accesses.  Which has resulted in 200M of memory for
the process.  This appears to have lowered the number of restarts, but
not eliminated them.

In your experience with this problem have you noticed /manage and or
traffic volume to have any impact on the frequency of restarts?  We've
been looking everywhere to determine what may be going wrong, and have
experienced the most restarts when traffic and /manage volumes are up. 
We unfortunatly have our most /manage volume within the same timespan as
our heaviest traffic.

Hopefully we can find a solution to this.  Thanks for the feedback.  Let
me know if you make any headway.

Hello,

I still can't figure out why my DTML document gives me the following
Zope error :

    Zope Error

    Zope has encountered an error while publishing this resource. 

    Error Type: AttributeError
    Error Value: __call__


when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?


Thanks in advance,
Greeting,
Eric

This is what happens when an exception is raised while rendering
standard_error_message (obtained through acquisition).

ZPublisher renders the default standard_error_message, rather than let
a problem go unreported.

Hi,

As I found out - you can not index numbers and therefore not search 
for dates using the zCatalog.

But I was wondering 'bout workarounds. I thougt maybe if I could 
change the bobo_modification_date to one of my own. That I could 
search for. But that seems like a pretty crappy workaround...

Ideas.... anyone ???

Has anyone modified the Zope index method to also index numbers ??

Sorry to butt in on an ongoing conversation, but:

Is it possible to do a redirect if a NotFound error is reported.

I'm trying to do this right now and failing miserably.

Any insight?

I think that's probably wrong. The thread-safety-ness of MySQLdb is that
two threads can share the module. You can't safely share connections, but
this is more of a MySQL limitation than a MySQLdb limitation. Of course,
you can share connections if you wrap a mutex around it so that only one
thread uses it at a time, but it is far better to have multiple
connections: Each connection is a seperate MySQL thread on the server
side.

The old MySQLmodule was probably thread-safe, but not thread-friendly: If
you ran a blocking operation (like a query), it would block all the
threads (i.e. it did not give up the Python interpreter lock during
blocking calls). This apparently causes really bad performance with Zope.

I may be deficient on Zope zen, but it seems like you would definitely
want to have several connection objects around, perhaps one for each ZSQL
Method, so that these can all work in parallel. From a security
perspective (i.e. you aren't just paranoid, you know they are out to get
you), this may make sense, as you can set up seperate users in MySQL with
very specific privileges, so each connection object can only do one thing
and can't be hijacked for something else.

Yup, just discovered this myself. :-) I put a buggy dtml expression in the
document and Zope displays a default message rather than the custom one
I've generated - removing the buggy stuff brings the custom version.

Thanks to Martin for pointing me to the 404 handling on zope.org, I've
solved the initial problem I was having with getting changes recognised in
the standard_error_message in Zope's root, and now have it mailing a basic
error report to the webmaster.

There are a few issues Chris noticed when he was doing some stuff, but I'm
going to take a look at these further before posting more on the subject.


Cheers,

John

Have you looked at the Zope.org error message and played with that? You should
be able to do a RESPONSE.redirect I think.

Martijn,

Yeah I look and even copied the code and fixed it to work on my server but
doing a redirect doesn't seem to work.  At best I get a blank page with no
redirect taking place.

Oh well, I'll keep on experimenting.

See ya

Hi Zopistas!

I need to get rid (completely) of some items in REQUEST that were 
passed from a form. Is there an opposite to REQUEST.set() that 
deletes instead e.g. REQUEST.delete() or so?

Jens,

You may want to look at Pavlos Christoforous' FSSession or Anthony
Baxter's SQLSession products to make this happen.  Look on zope.org.

Not a problem. Use ZSQL Sessions and an update SQL statement have it fed in
from a Zope form. Do a little error checking and Bob's Your Uncle.

I don't think this is true. Catalog does not index numbers in TextIndexes,
but I think a FieldIndex would work fine. I'm pretty sure I've done it (with
dates, even), but not 100% sure.

Just make sure you use a FieldIndex, and I think you'll be fine.

Hi,

    Take a look at the FSSession and SQLSession products. They allow you to
store data on the server for each user, and I think it would be pretty easy
to implement a shopping cart that way.

Hi,

  I went thru mailing list but I did not find a
response to my problem.

I've written simple form with one text field and one
file type:

<form action="/content/result" method="post"   
ENCTYPE="multipart/form-data">
<input name="c_title" width=30 value=""> 
<input type="file" name="c_body:file" width=30>
<input type="SUBMIT" name="SUBMIT" value="Submit">
</form>


result method is:
....
<dtml-call "manage_upload(REQUEST['c_body'].read())">
<dtml-var REQUEST>
....

When I press Submit button I get

Error Type: NameError
Error Value: manage_upload

Any suggestion?

b) How can I simply affiche (if I find a PB) the
upload content in browser?

c) How can insert uploaded content in MySql. I Have to
use:

VALUES
(
'<dtml-var c_title>',
'<dtml-call
"manage_upload(REQUEST['c_body'].read())">'
)

It works? it seems bizarre?

Thank's

The REQUEST object is defined in ../lib/python/ZPublisher/BaseRequest.py. I
don't see a delete there, but by studying that code, I'm sure you could
easily implement one.

Subject: [Zope] newbie CGI question
Message-ID: <Pine.OSF.4.02.10003211327080.9449-100000@batman.tamucc.edu>

I currently have a site that uses numerous perl cgi scripts....I have
successfully managed to transfer all the static pages to Zope...however,
what about CGI scripts?  Does Zope support them?  Can I use the Zserver
with these scripts or should I use the other server (with Apache)?

Also, from the Zope experts out there, I need your opinion.  I am
considering using Zope for my existing web site (it's fairly large)
...however, I would still like to continue to use perl/cgi, (have a
lot of time invested in my already existing scripts), and not use much
Python (no flames please...haha).  I like the graphical capabilities of
Zope, and the ability to assign roles to  certain users...but I don't know
if this is worth switching, especially if I am going to continue to use
perl/cgi (if that's even possible)...any suggestions out there?

Thanks in Advance,
Jessica

It seems to me that all this would require is passing the "_" namespace in place
of the REQUEST when calling the ZSQLMethod -- am I missing something?  Values
found in the REQUEST would still be found, but would be overridden by any
intermediate namespaces (e.g., from dtml-in, dtml-with, or dtml-let).

[RH] REQUEST is a python dictionary, but probably one that DC has altered
for security (or other sound reasons). I once used REQUEST.clear(), which
flushes the whole REQUEST  (this was necessary because I wanted to do a
batch operation on a fileobject of 500K , but didn't want to pass it around
several times). This worked, I believe (but I never tested this through).

Martijn, you're right. Nobody would use Win98 on production systems. But
quite a
few people use it on their notebooks or home PCs for development, I guess.
At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS
in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and
restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Joachim.

[RH]Hm, I have been developing for quite some time on an feeblish win95
machine at home, which repeatedly crashed, but I have never ever lost
committed transactions. Strange.

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in

Hello,

I still can't figure out why my DTML document gives me the following
Zope error :

    Zope Error

    Zope has encountered an error while publishing this resource.

    Error Type: AttributeError
    Error Value: __call__


when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?

[RH]Can you send us more detailed information:
the exact dtml for the local and the subobject method and the traceback of
the error (you can get it by viewing the source of the error page)

The REQUEST object stores form data in its .form member, which is a Python
dictionary.  You will need to find a way to execute the statement, "del
REQUEST.form[ 'variableToErase' ]", or the equivalent expression, "delattr(
REQUEST.form, 'variableToErase' )", neither of which can be done from DTML or
from PythonMethods (ergo, must be done in an ExternalMethod or done from a
Python product).

My Very First External Method (TM) -

def removeRequest(REQUEST, item):
    "Remove an item from a REQUEST.form"
    try:
        del REQUEST.form[item]
    except:
        pass
    return None

And invoked (once instantiated by the Management Interface) with

<dtml-call "removeRequest(REQUEST, 'form_variable')">

(Note that the except clause should really be trapping for KeyError -
version 1.1 will definitely have this :-).

Message-ID: <PKEBIHPBEGMAPMNHFPCFGEGNCKAA.jlv@volition.org>

Hi.

I installed Zope 2.1.6 on a W2K machine and have one problem installing
additional components.

I have tried to install TinyTable, Squishdot, Photo, ZPhoto-Album, and
others but NONE of them get noticed by Zope when re-starting the service.

A clue, I believe, is in this error message when trying to "import"
ZPhotoAlbum.zexp:

---
Zope Error
Zope has encountered an error while publishing this resource.

Error Type: Bad Request
Error Value: File does not exist:
C:\PROGRA~1\ZOPE-S~1\import\ZPhotoAlbum.zexp
---

Shouldn't that directory be:

C:\PROGRA~1\ZOPE-S~1\inst\import\ZPhotoAlbum.zexp

???

None of the lib installations that would be in ..\inst\lib get noticed upon
restart, which leads me to think that somewhere in the installation it
doesn't have the "installation" setting correct.

Thanks.

Jason

I always thought the inst directory was used by Zopeat install time and only
then.

Any products should go into <zopedir>/lib/python/Products

Any zexp files hould be in <zopedir>/import

You shouldn't need to put anything in the inst directory.

I'm pretty convinced it's related to glibc version - the fact that a strace
of the process shows it repeatedly opening/selecting over more and more
fd's just before the process goes away suggests some sort of funky error
handling to me - maybe one of the socket handling routines had a change in
what error it produces between glibc versions?  Anyway, I haven't had time
to sit down and properly dig.

2.1.6 suffers the same problem.

I can reproduce it instantly with a large enough page - stop the request
mid-way, the closing of the socket to the client while Zope is serving the
page up seems to be what causes it to go into it's loop, then die.

Mondo apologies to the zope crew for not putting this in the collector - I
had hoped to find the actual problem (and maybe a solution) first, but ran
out of time :(

Sometimes you do, sometimes you don't. I know that sometimes I can acquire ZSQL

I haven't been able to figure out what the rules are, either. If anyone out

Ok,  I finally did it.  I got my boss to slip a nice little application
server in the budget.  So here I am trying to spec out a nice Zope server.  
 
What should my priorities be when building this beast,  I think we'll be
able to spend about $10 Grand on this beast.  We will be running a secure
site using Apache and OpenSSL,  and we are targeting about 100 continuous
concurrent users.  I have already set SOME priorities, because uptime is a
big issue so the server will have redundant power supplies and hardware RAID
5.  
 
Beyond that,  what do you suggest.  Is memory more important than processor
speed?  Is it important to go with a Multi-processor server or will Zope/
Linux take advantage of a multi processor setup?  
 
 
Dream a little server for me :)

You will have to use Apache + mod_perl + mod_rewrite + Zope.
This way, you send the CGI requests to the cgi-bin, and the
rest requests to Zope. The details could be somewhat involved. :(

(see the following quote in
http://www.apache.org/docs/mod/mod_rewrite.html

`` Despite the tons of examples and docs, mod_rewrite is
voodoo. Damned cool voodoo, but still voodoo. ''
-- Brian Moore
bem@news.cmc.net
)

But it is definitely worth it. And I would guess many people
out there actually use this configuration.

I guess it is possible for someone to write some Zope product
for Perl (a la mod_perl), but it would be major engineering to
be fully compatible with Perl. If you don't mind re-launching
the Perl interpreter every single time (I know, it's primitive),
it's easy to execute the perl command from a Zope external method.

For now, the best bet is probably Apache + mod_perl + mod_rewrite +
Zope.

Hung Jung Lu ,
Along these same lines, I have a C++ CGI App that I would like to call from
zope.  It requires a couple of parameters.  The app can either return HTML
or I can have it save the output to a text file.  Ultimately, the text will
need to be displayed to the user from Zope.
Q1.  How does one call a C++ CGI program from Zope?
Q2.  How do you supply the C++ CGI program with "command line" parameters
from Zope when making the call?

Thanks,

Eric.

The intent of ZOPE is to replace writing CGI scripts. Zope itself often
runs as a large persistent CGI script. It has several advantages over
traditional CGI scripts detail on zope.org.

The general answer is that you'll need to put the CGI scripts in a
non-ZOPE location to use them.

I suggest deprecating your CGI scripts in favor of ZOPE classes.

Oh boy... 10 Grand?

IBM Netfinity 5500 M20

- Dual 700 MHz
- 5 x 9.1 GB RAID 5
- 2 GB RAM
- Dual NIC Cards
- RH 6.1 

Should be about 10 Grand. That thing is ROCK SOLID. It could eat 100
Concurrent users without a napkin. Can handle up to 4 GB RAM, 120+ GB of
Drive and 4 Processors. Almost everything is hot swappable (power, fan, PCI)
only time you would have to bring it down would be to so you could take it
home.

The other way to go would be to get 2 x Netfinity 5000 (Dual 700 MHz, 1 GB
RAM, 3 x 9.1 GB RAID 5). Load balance them and you are golden.

Enjoy...

Subject: [Zope] Zope hosting
Message-ID: <20000322010840.A1674@rosa.sferacarta.com>

Hallo! I'm thinking about using zope to develop some sites.

May you please advise me about a Zope hoster?
I've looked at those listed on zope.org, but some of them offer
just 20MB or have most of the site written in german.
One of them I can't even reach, others don't mention zope on
their pages, or are a bit on the pricey side.

I need a flexible, expandable solution. I may need 40MB and two
domains for a start, and more in the future. I have to install
my products and use pgsql or mysql.

Shell access is welcome, too..

Do you have some suggestion?
Which ISPs do you think are best?

 - OR -

Do you think I'd better install zope as a normal user, on one of
those cheap ISPs that give me 500MB ?


Thank you very very much.

Message-ID: <38D80AF9.3FE3909F@netspace.com.mx>

Hello,
I recently started to work with php (+ Apache), and now I found Zope. At
the first sight, Zope seems to be faster than php, but I don't know if
it's my php application that is not so complex than Zopes objects. So I
would like to ask, is there a benchmarks or articles or any sources that
discuss about performance and developing PHP versus Zope? Also, i am
cuirious, was Zope developed to replace PHP in the future? And what if
PHP comes up with an interface like Zope, so what would be better? Many
questions, isn't it ....

Any comments are welcome.

Thanks.

Field indexes can index any kind of picklable object value, including
DateTime objects.  This is how searching by date is done on the Zope
site.

Keep the cgi scripts in Apache, migrate to Zope at your leisure.

Zope, more correctly Python will not take advantage
of a dual processor. 
I probably seriously consider buying a ZEO solution
from DC. 
I don't know, but a ZEO solution might solve the 
problem with 100 continuous concurrent users
writing to the ZODB?

Yes it will, it just won't scale exactly two fold.  In almost all Python
wrapped C calls, the C code releases the interpeter lock as often as
possible, this allways happens, for example, when doing I/O or when
calling  database library routines.  Two processors will give you a
noticable benefit.  Four or more will probably not.

Further, Zope will not be the only process running, so a dual gives you
the usual benefits, like doing a compile on one thing without killing
your website.

ZODB FileStorage was not designed to be write intensive, the goal is to
provide a mid-write high-read solution, this solution satisfies 99.9% of
all web site needs.  You would be surprised how much money you have to
pay to Oracle to get, for example, their high write-write distributed
database solutions (its in the six figures).

ZEO is a distributed storage, but in the end it depends on a mechanism
that actual writes the data somewhere.  In the stock case, this is a
FileStorage.  If you want high-write intensity, consider a
BerkeleyStorage (which works fine as the backend for ZEO) or offload
alot of your high-write intensive data to a relational database.

The unique id problem come up again and again.

The automatically generated unique id will benefit web author with

sql row id
object id

and may be some others

With a view that zope will be run over the network with distributed storage
across the net, I would like to suggest we implement a unique id server
which can be a zope server serving on another port and serialize all request
and return the globally unique id.

Does this work?

I also suggest zope can be configured to automatically get the object id
from this service and have globally unique object ids.

Rgs,

Kent Sin

As far as multiprocessing goes,  if I were to run a MySQL database on the
same server (serving primarily to Zope) then the multiprocessor config would
be a very big performance boost wouldn't it?

What about Memory?   Again with MySQL.  I suppose I should have mentioned it
right of.  Our main goal is to serve up pages from a database that will be
about 500MB-1GB in size.  There will be very little information which will
be cachable,  almost all of the queries are unique.

Yes it will, it just won't scale exactly two fold.  In almost all Python
wrapped C calls, the C code releases the interpeter lock as often as
possible, this allways happens, for example, when doing I/O or when
calling  database library routines.  Two processors will give you a
noticable benefit.  Four or more will probably not.

Further, Zope will not be the only process running, so a dual gives you
the usual benefits, like doing a compile on one thing without killing
your website.

ZODB FileStorage was not designed to be write intensive, the goal is to
provide a mid-write high-read solution, this solution satisfies 99.9% of
all web site needs.  You would be surprised how much money you have to
pay to Oracle to get, for example, their high write-write distributed
database solutions (its in the six figures).

ZEO is a distributed storage, but in the end it depends on a mechanism
that actual writes the data somewhere.  In the stock case, this is a
FileStorage.  If you want high-write intensity, consider a
BerkeleyStorage (which works fine as the backend for ZEO) or offload
alot of your high-write intensive data to a relational database.

Does there have to be any meaning to the keys?

IOW, would a random, unique id work for you?

If so, you can take a look at:

http://www.zope.org/Members/Bill/Documentation/AutoGenID

For ways of doing it. You would insert the generated id into the SQL
table instead of the id field of a zope object.

If you are doing this inside a <dtml-in> tag, you can use the sequence-id-odd
and sequence-id-even vars, thus:

<dtml-in someSequence>
  <dtml-if sequence-id-odd>
    <tr bgcolor="blue">
  <dtml-else>
    <tr bgcolor="red">

Legacy.  python expressions were added after sequence-item.

Use the namespace object as a mapping:

<dtml-call "foo(var=_['sequence-item'])">

I asked much the same question whilst replying to a very similar question
recently.  the -'s in the names is from times predating Python expressions
(afaik).

to access that var, use the _ namespace:

<dtml-call "foo(var=_['sequence-item'])">

Sure, I do it all the time. The following way is the fastest I came up with:

- Create a style sheet that looks like that:

// even rows
td.listrow1 {
       color:        blue;
}

// odd rows
td.listrow0 {
       color:        white;
}

Then write a DTML method/document (for example displaying objects in a folder):

<table>

<dtml-in "objectValues()">
   <tr>
       <td class="listrow&dtml-sequence-even;">
           <dtml-var title_or_id>
       </td>
    </tr>
</dtml-in>

</table>

sequence-even returns a boolean  set true (1) when we have an even row.

This is untested code, but should work.

Stephan

First, you didn't provide a traceback.  Please allways send a traceback
with an error report otherwise we can't really help you.

Second, I can't reproduce the problem you describe.  I uploaded a file
into Zope, and randomly click a dozen or so checkboxes a dozen times,
and no error ever occur when I click 'Change'.

How, _exactly_ do you get this to happen?

 Our project has a requirement to have all artifacts under source
 control (in this case ClearCase). What is more, our defect
 tracking system is intergrated into our source control system
 such that work done on defects can be traced to versions in the
 source control system. The key requirment is tracability.  Any
 work done can be traced back to when, where, how and why and
 vice versa.

 The problem is Zope. To have meaningful tracability in zope
 means have some system whereby a representation of the zodb
 exists in source control and any changes by users are
 automatically reflected in the source control. The ability for
 the source control versions to be imported back into Zope would
 be a plus.

 Any ideas?

 When building a Product using ZClasses, I often want to create
 a "root" ZClass, which the manager will create in a normal
 folder, and which will then expose the Product's other ZClasses
 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel
    +- FooProduct
       + FooItem_add_permission
       +-FooRoot
         +- FooItem
         +- FooItem_add

 Hmmm, I don't seem to be doing so well on picking topics.  Here
 is what I had in mind:

  * This site is an instance of the 
    "ZGotW product":http://www.zope.org/Members/tseaver/ZGotW,
    which has a "main" factory, ZGotWRoot_factory, in its root
    folder.

  * This factory does *not* create an instance of a "folderish"
    ZClass, but rather, creates a normal Folder and populates
    it from a set of default DTML objects, along with a ZCatalog.

  * Individual issues of ZGotW are created within this folder
    as instances of the ZClass, ZGotWIssue, using the code in
    those "cloned" DTML objects.

 My rationale for adopting this approach, rather than creating
 a "folderish" ZClass, was to allow each instance of the "root"
 to be independently customized;  the "common" behavior of a
 ZGotW site is included in a set of utility methods, which can
 be tweaked to enforce different policies, or change the
 look-and-feel of a particular site.

 The downside to this choice is duplication of code:  should I
 find a bug in the original, default code, I have to then fix it
 in each instance as well as the Product.

 Comments, anyone?

Ethan,

Welcome to WorldPilot! (Note: I am not connected with the developers just a
user.)

In order to see other users names in any of the PIM areas those things must be
shared from the sharing page associated with the content type. In the Notes
section it works as follows and I assume similar for the other sections though
I haven't had time to work it through all the paces. If you have browse access
you can see public postings, if you have read access you can see public and
confidential postings. When in Notes any of the users who have shared
information that you can see will become visible. Example:
Tester1 enters 3 notes: 1 private, 1 public, 1 Confidential.
Tester2 has browseable; read access to Tester1's Notes. 
Tester3 has browseable access to Tester1's Notes. 

Both will see Tester1 as an option in the user selection under notes. Tester2
will see 2 notes and Tester3 only 1.

HTH,
Jack

Message-ID: <4.3.1.0.20000321214257.00a81ee0@mail.cbu.edu>

Here is my take on it:

- Never have something high-volume-write to ZODB.
- Use RDBs and LocalFS or other ports to write to the File System.
- If you really need to large data in Zope format look at plugable brains, 
the idea is great.
- I noticed PCGI and Apache increases your performance, especially when you 
serve up big files.
   Setup: Apache using virtual hosts HTTP & HTTPS running Zope PCGI, for 
Images and for large files.
             My Images are served using port 81 and Documents using port 
82. That worked very well so far. We still have to test it live.
- I have two servers running: One for the DB and one for the rest: Mail, 
HTTP/HTTPS, Zope, SSH ...
- Even though not much is going on, the Web server has a constant use of 
400 MB RAM (so I would suggest 512 MB RAM)
- The DB server should be your real performance working horse. Buy a 
computer that will reflect your DB load...get a lot of memory though (1-2 GB).
- Put in both servers a dedicated NIC only for the DB info transfer.

I think that will  get you going pretty well. For the Web server Processor 
power maybe more important than for the DB server. That completely depends 
on how much you team likes SQL (meaning, how much logic is done using SQL).

Message-ID: <l03130300b4fe04b0d651@[206.221.224.184]>

In a technological sense, comparing PHP and Zope is a little bit silly,
since they are so very different.  In a practical sense, comparing them
is extremely reasonable, since there are a wide variety of web development
tasks which can be approached with either PHP or Zope.

Performance comparisons are the toughest.  PHP is no slouch -- it is used
for some very high traffic sites, including freshmeat.net and lots of
others.

Zope, on the other hand, offers some features which will cause it to
outperform stock PHP in many cases.  PHP is a scripting language for
website development.  In contrast, Zope is described as an application
server.  As such, Zope includes features like pooling of database
connections and caching of database query results.  These are not
as easy to do in technologies like PHP, and they can make a huge
difference in the performance of database-driven sites.  We
implemented www.CodeCatalog.com twice -- once in Zope, and once in
PHP.  The Zope version ended up much, much faster.  Your mileage
may vary.

I'm pretty sure it's possible to get good performance from PHP and
Zope, if your situation is appropriate and you're willing to work at
it.

I am equally sure that it's pretty easy to get lousy performance from
either PHP or Zope, if your situation is especially inappropriate, and
you're willing to live entirely off the low hanging fruit.

There are lots of other comparisons which could be made, and have been
made.  These comparisons tend to degenerate into flamewars pretty quickly,
although I see no reason for this to happen.  Objective comparisons
of two technologies like this are useful.  I happen to like both, although
Zope certainly gets an increasing share of my attention.

Zope's three-tiered architecture and web-based authoring tends to make
the tool more approachable by people who may be less technical, and
more annoying to hardcore programmers who find they have a new paradigm
to learn.  The gap between the experiences of these two groups of
people tends to narrow very quickly as people start to grasp the soul
of what Zope is all about.  People who are learning Zope tend to
periodically burst out of their office with a desperate need to
tell someone about the latest core principle of Zope which they finally
came to understand.  The more you have these "light bulb" experiences,
the cooler Zope is.

PHP isn't like that.  It's an excellent tool, but it's really just
a scripting language.  It isn't everything that Zope is, and it
doesn't try to be.

Compare PHP to Python

Compare Zope to Midgard.

BTW, the safest way to do those comparisons is *probably* to do them
somewhere other than on this mailing list.  :-)

Subject: [Zope] Zope : Load_site features request
Message-ID: <000501bf93cd$87f93c20$770da8c0@bbs>

Load_site is a greate product.

I am using it to upload a brunch of files to zope now, I found I have an
idea :

In order to make the uploaded zope more alive, I would like the load_site to
make everyfile in the original archive an folder in zope, with index.html
representing the structure of the original html file. And all the contents
goes to obj1, obj2, .... reside on the same folder. For example,

Index_html :

<dtml-var standard_header>
<body><p><dtml-var object1></p><table><tr><td><dtml-var
object2></tr></td></table>
</body>
<dtml-var standard_footer>

This would make the resulting zope site more close to the zen of Zope.

I am not very good in python but please give me some hints to made this
modification. Will you make the change?

Rgs,

Kent Sin

Message-ID: <38D87A4A.FFBE3FF4@fr.bosch.de>

Hi Zopistas

while trying to make gtk's (very useful) Boring Product (slightly
more) interesting, I came across the following (for me) strange
behaviour.

manage_ methods seem to always have "REQUEST=None" as their last
parameter. If I remove the "=None" from manage_edit then I notice no
difference, so the actual parameter is presumably being passed.
However if remove the complete formal parameter (and the reference to
REQUEST in the body of the method) 

def manage_edit(self, title): 
        """does this really need a doc string?"""
        self.title = title
#	if REQUEST is not None:
#	    return MessageDialog(
#		title = 'Edited',
#		message = "Properties for %s changed." % self.id,
#		action = './manage_main',
#		)


then everything still works ! Why is python not complaining about a
parameter mismatch ?

I promise to publish a Howto on making Boring more Interesting when
this madness is  over.

Thanks in advance

Mark

Thanks. That is the current work-around that I am using...
(Key derived from a time-stamp with millisecond precision.)
There is one observation and two problems:

(1) ZopeTime is not as good as the getdate() function
    from Sybase, if you are running multiple Zope
    webservers (for load-balancing.) That is, it's
    better to rely on one unique source of timer.

(2) There is a slight chance of two processes getting
    the same key, if they happen to occur within one
    millisecond of each other. The probability is small,
    but unfortunately I have to address even this minuscule
    probability. :(

(3) If the server's time is re-adjusted for any reason,
    it's possible that some keys are regenerated.

I agree that the millisecond-precision key is really good
for non-critical applications. But because of the nature of
our project, we need to address even the slightest chance
of error. :(

I think I will adapt the Sybase's recommended stored procedure
to Zope, by using DTML and ZSQL methods. It's kind of nasty
for something as simple as a surrogate key generation, but it
seems more secure.

thanks again,

Hung Jung

hmm, i must admit that I still can't get it to work with simple 
numbers. I have a field with the number "20002" but it doesn't matter 
wether i use text or field index it still don't work. Am I forgetting 
something ?? And yes - I reindex the cataloge before searching.


But I will look into the date thing right now!!!

Because Zope passes in those parameters that the method asks for. If you take
away the REQUEST parameter, Zope simply doesn't pass it in.

The manage_ methods use REQUEST=None to make sure you can use the methods in
situations there is no REQUEST to pass in. You can call manage_edit with a new
title, and have it still work, from a DTML Method without having to pass in
the REQUEST object, as you won't need the MessageDialog anyway.

Hi.

I am wondering if I can do a search/replace in the ZODB
for e.g. every DTML Document (just like search, but with a replace-with field)?
Is there anything planned or under development?
This would be rather useful to easily use Acquisition
with content imported from HTML files.
Someone could replace a menubar (which appears in all files the same)
just with the <dtml-var ...> call and create a DTML method
which holds this content.

CYa,

I think this is my point exactly ;-)

It all seems really inconsistent and I was wondering if anyone could say exactly what the 'rules'
were and why?

Interesting topic!

How does Zope compare with Midgard?
Which one is more flexible (that is: which one can be used in a wider set of
cases)?
Which one is easier to learn for the webmaster?
Which one is better fit to develop and maintain a complex web site (let's
say: 10,000 documents and 50,000 pictures, updated weekly)?
Which one is better for web sites that uses database and/or a "fragmented
document" architecure (XML/SGML documents that are disassembled and
re-assembled on demand)?
Which one can better integrate other technologies (web-mail interfaces and
so on)?
Which one is easier to use for a remote customer, enabled to develop and
maintain his pages on the server?
Which one is better for "workgroup" intranet servers?
Which one is safer (more anti-hacker)?
Which features does Zope have that Midgard does not have?

Thanks.

PS What does "Midgard" mean (I'm italian...)?

stephan, 

i agree on apache increasing your performance when serving static
files (for instance images), but wouldn't url rewriting and the proxy
pass module of apache be an even better solution? i just switched from
PCGI to the Rewrite/Proxypass combo because of the additional overhead
of PCGI. 

(see http://www.zope.org/Members/anser/apache_zserver/ for the kind of

Mmmhh, I have to have a look. Okay, I just read the the little tutorial. 
Does it really speed things up?
I guess SSL should not be hard using this solution. I will be thinking

Subject: [Zope] Upload files in Zope and store elsewhere
Message-ID: <38D8B1FC.CCDA0827@funcom.com>

After some helpful advice, I have been successful in uploading files
(images) to Zope. Now I am trying to stuff the uploaded images in a
MySQL database, but am not able to access the image data.

If I try to stuff the image data "raw" into the database by declaring a
image:string parameter to the ZSQL Method and  <dtml-sqlvar image> in
the ZSQL code I get a string like "<ZPublisher.HTTPRequest.FileUpload
instance at 87956214>".

Another approach I have tried was <dtml-var image fmt=sql-quote>, but
this complains about the image being an instance and not a string.

Another approach has been to access the actual "raw" image data using
image.data in various combinations, but I have not gotten this to work
anywhere (contrary to what it seems other people have managed to do),
see this 

http://www.egroups.com/group/zope/26227.html?

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

Marius Kjeldahl

Hm, I _think_ I recall (but I can't test this right now) that the ZSQL
method will only accept values that are given explicitly in its
arguments and in that case it will also acquire them. That would make
sense from a security point of view.
Or perhaps it was a bit more complicated - I have to investigate this

some testing with apache benchmark:

the setup is an apache 1.3.12 sitting on port 1988.

/tstfolder/bmeth is a very simple dtml method ("i am bmeth in
/tstfolder" <dtml-call "REQUEST.set('testvar', 'hm...')">
&dtml-testvar;). 

i do 1000 requests at 50 concurrent users, keepalive-connection via
apache benchmark:

first the result of doing a proxypass to zserver on port 8080:

   --------------------


conclusion: with proxy pass i get around 30% more requests per second
and around 25% less connection time (and im not able to use keep-alive
as it seems).

please note that this is only a quick check and not scientific in any
way, and naturally the benefits will diminish when more complicated
pages are going to be served.

if there are any other test results please let me know...

peter.

Hello Marius,

TI am a Newbie to Zope and this is the first time I post a Answer to the
mailing list. But I had the same problem and I hope I can help you.

After a lot of test I find out the following method to upload images to
MySQL and after that retrieve it in the web pages.

Write the folliwing ZSQL method:

       Arguments: N_
                  Titulo
                  Subtitulo
                  Texto
                  Foto

      insert into Novedad
        (N_, Titulo, Subtitulo, Texto, Foto)
      values (
        <dtml-sqlvar N_ type=string>,
        <dtml-sqlvar Titulo type=string>,
        <dtml-sqlvar Subtitulo type=string>,
        <dtml-sqlvar Texto type=string>,
        <dtml-sqlvar
"_.string.replace(REQUEST['Foto'].read(),'\010','\\010')" type=string>
      )

Note that I replace the octal char 010 by the string "\\010".
If you don´t escaape this char MySQL change it for the char 008. I don't
know why.
To upload the image I have the following DTML Method:

<form action="novedades" method="post" ENCTYPE="multipart/form-data">
  <input type="hidden" name="accion" value="insertar_novedad">
  Nş producto: <select name="N_">
    <dtml-in listar_N__producto>
      <option value="<dtml-var N_>"><dtml-var N_></option>
    </dtml-in>
  </select><p>

  Texto: <textarea rows="8" cols="40" name="Texto"></textarea><p>
  Foto: <input type="file" name="Foto"><p>
  <input type="submit" name="submit">
</form>

Note the the line "Foto: <input type=....".
And to retrieve the image I have this DTML Method:

Method name: image

    <dtml-in obtener_foto>
    <dtml-call "RESPONSE.setHeader('Content-Type', 'image/gif')">
    <dtml-call "RESPONSE.setHeader('Content-Length', _.len(Foto))">
    <dtml-var "_.string.replace(Foto,'\\010','\010')">
    </dtml-in>

Note that you must put the 5 lines in the same line (without newlines).

ZSQL Method name "obtener_foto":

      Arguments: N_

      select Foto
      from Novedad
      where
      <dtml-sqltest N_ type=string>

To insert the image in an dtml method:

<img src="image?N_=AC-M56E">

Hope this can help you.

Excellent, just what I was looking for. 

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

and this to anyone who wants to answer: ;-)

3.

   Anyone know why? This is a little disturbing...

Subject: [Zope] Q: <dtml-in sort=twofields>
Message-ID: <E12XlPG-0002fb-00@home.delysid.org>

Hi.

I am constructing a search interface for a catalog.
The objects I index have three relevant properties:
title (textual title)
id (the id, sortable)
book_title (the name of the book where the chapter is included)

I want to have atabular result like this:

Book 1     Chapter 1.1
           Chapter 2.1
Book 2     Chapter 1.1
           Chapter 4.2


To acomplish this I currently do something like:

<dtml-in Catalog sort=id>
  <tr>
   <td><dtml-if first-book_title><dtml-var book_title></dtml-if></td>
   <td><dtml-var title></td>
  </tr>
</dtml-in>

But, to have the list look nice, I'd need to specify
two fields for sorting, book_title should be the primary
field sorted by, and id should be the field all identical
book_title entries should be sorted on.

Is there a way to do this with dtml-in?

CYa,
    Mario <mlang@delysid.org>

here you are! (see end of post)(i hope you dont mind my adressing

btw. does anybody know of other benchmarking software? (i once tried
to grab httperf but the ftp site holding the source is down...)

So ProxyPass is 20 % faster. Cool. I will try that.

Subject: [Zope] Names containing colons?
Message-ID: <200003221420.IAA08813@beluga.mojam.com>

In my web page input forms I've been using field names like "radius:int" so
Zope will coerce variables to the proper type.  This works fine on the
server.  Unfortunately, if I have a JavaScript function on my web page to do
form input validation, how do I reference that object?  Is there some
alternate naming scheme that will allow Zope to do the type cast and allow
references from JavaScript?  Should I just forego the :int stuff altogether
and do the coercion explicitly?

Thx,

In your JavaScript functions, reference the variable as such:

forms[0].elements["radius:int"]

(Replace the "0" with an actual name if you've named your form . . .)

If a "folderish" ZClass had some way to expose its customizable parts, so
that you could go to an instance and say "instantiate a local copy of method

Excellent, just what I was looking for.

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

It's BLOB

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

< 1MB

and this to anyone who wants to answer: ;-)

   Anyone know why? This is a little disturbing...

From Python (either an ExternalMethod or a product)::

  import sys, os, string

  def ExecCGI( cmdLine ):
      """
      Run an external command and return its standard output as a string.
      """
      f = os.popen( cmdLine ) # note that Win32 has a non-standard popen()
      lines = f.readlines()
      status = f.close()
      if status:
         raise "CGI returned error: %d" % status[1]
      return string.join( lines )

To call it from DTML, passing the current values of 'foo' and 'bar'::

   <dtml-let cmdLine="'/path/to/my/cgi %s %s' % ( foo, bar )">
     <dtml-var "ExecCGI( cmdLine )">

I am happily using CodeIt.  They offer several options above "basic" Zope
hosting:

  * Install your own products (this is their "professional" option).

  * Add disk space cheaply (they quoted me $0.50/month for each added 10 Mb).

  * Add domains, mapping them to separate Zope folders, for $10/mo each.

> Shell access is welcome, too..

They don't offer shell access -- I FTP products, export files, etc., into a
"home directory" with a slightly oddball layout.

Zope wants to be a long-running process, with significant CPU and RAM
requirements;  most ISPs don't appreciate you running such a beast, so ask
first.

Subject: [Zope] Zope Weekly News
Message-ID: <Pine.BSF.4.21.0003221005110.8916-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday before Noon.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * Two new Zope revisions were released this week.  2.1.5 filled in
    security holes which affected sites which allow untrusted users to
    create DTML documents.  Ironically, a bug-fix which was included
    in 2.1.5 broke code which depended on the bug.  This was fixed in
    the second release, 2.1.6.

    http://www.zope.org/Products/Zope/2.1.5/Zope_215_release
    http://www.zope.org/Products/Zope/2.1.6/Zope_216_release

  * Thanks to Eduardo Fernandez Corrales, the Zope Weekly News is now
    available in Spanish!  He is publishing translations at Zope
    Hispano, a portal for Spanish-speaking Zope developers and users.

    http://zope.sistelnet.es

  * Healtheon | WebMD is hiring in Atlanta, GA

    Healtheon | WebMD is looking for Software Engineers with
    experience in Python and/or Zope to work in our Global News Center
    located in Midtown Atlanta, GA. You must be willing to relocate.

    http://www.zope.org/Members/kbirch-webmd/hiring-notice


New Products

  * The Portal Toolkit has been packaged into a snapshot release for
    use by those who do not have access to CVS.  The PTK is targeted
    at community-oriented portals, but is also appropriate for any
    site which wants to give members a personalised view of content.
    The snapshot release is 0.7.1.

    http://www.zope.org/Products/PTK


Updates

  * Software Product: load_site.py with additional features, by Itamar
    Shtull-Trauring

    Itamar has updated his powered-up 'load_site.py' again.  The
    present release is 1.3.1.  This update adds a GUI, built with
    wxPython.  'load_site' is a utility for dumping content from a
    file system into the ZODB.

    http://www.zope.org/Members/itamar/load_site

  * Software Product: ZopeEDIT, by "jimbag"

    The latest release of this product, 0.0.5, adds limited RPC
    support which is used to create and delete folders.  ZopeEDIT is a
    tool which enables any text editor to edit content on a live Zope
    server.  It does not need to run on the same machine as the Zope
    server.

    http://www.zope.org/Members/jimbag/ZopeEDIT/

  * Software Product: LocalFS, by Jonothan Farr

    Version 0.1.6, the Ides of March release, fixes several bugs, is
    more robust about determining file types, and creates XMLDocuments
    and StructuredDocuments automatically, where appropriate.  LocalFS
    is a product which allows Zope to serve files out of a local
    filesystem.

    http://lists.zope.org/pipermail/zope-announce/2000-March/000130.html

  * Software Product: SiteAccess, by Evan Simpson

    Evan has release version 1.0.1 of SiteAccess.  This version fixes
    a bug which interfered with FTP access to Zope.  The SiteAccess
    product allows Zope to serve different content depending on the
    hostname the site was accessed by.

    http://www.zope.org/Members/4am/SiteAccess

Zope.org items

  * How-To: VersionFTPServer, by "htrd"

    This How-To describes modifications to Zope which allow you to
    work within a Version through FTP.  Versions allow you to stage
    changes to a Zope site by effectively forking the database.
    Changes that you make in a Version are not publicly visible until
    you ask them to be.

    http://www.zope.org/Members/htrd/howto/VersionFTPServer

  * How-To: How To: Use GenericUserFolder with an SQL database Version
    1.1, by "hippy"

    This How-To shows how to customise GenericUserFolder(GUF) to use
    an SQL database as its repository for usernames, passwords, roles
    and anything else you want to store about a user.  The update adds
    information from Dennis Baker to help get things going with MySQL.

Midgard is a PHP and MYSQL integration.  Midgard uses MySQL the way Zope
uses ZODB, as well as relying on MySQL for the things that Zope can use
other databases for.  I would assume that Midgard is a logical step for
those coders that are used to making database-driven dynamic web pages
with scripting languages, and is probably intimidating to those that
don't come from that background.

On a brief overview, Midgard seems to want to exert more control over
your approach to content.

[snip questions I can't answer]

> Which features does Zope have that Midgard does not have?

Well... Zope is object oriented, transactional, can interface with a
variety of databases, uses and is written almost entirely in python. 
The web-management seems more robust, but I could be out to lunch.

> PS What does "Midgard" mean (I'm italian...)?

Midgard (should be Midgaard or Midgĺrd) is the Norse word for the
material plane, as opposed to Asgĺrd (the realm of the gods).

but be careful, since this is a security hole.  the executed command line

Hi,

The company I work for is getting into Zope hosting.
We're based in the UK and are pretty open minded since we've started doing a fair bit of work in
Zope ourselves.

If you or anyone else is interested in European Zope Hosting with a flexible, open-minded ISP (of
course, I would say that ;-) then contact 
Simon Coles (simon@nipltd.com) or myself.

Hope this helps,

Chris

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A095@express.sematech.org>

I messed around with this a little bit before giving up, though I'd like it to
work....

The problem (as I see it), is that 1) you have to get to the data and 2) you
have to format the data properly so that the database stores it properly.  What
I've gleaned is that the binary data will contain characters that confuse
whatever DA you're using (I use the ODBC adapter).  This means you'll probably
have to replace these 'confusing' characters with their 'safe' counterparts.
For the person who got it to work, it was the 0x08 character.  I believe other
DB's will choke elsewhere.  I never could figure out which characters needed
replacing and with what, so I wrote an external method to save the file and just
wrote the filename/location/upload info into the database.

This wasn't as nice as I wanted (I had security concerns putting anyone's files
on the hard drive), but it will probably work (I get sidetracked once I got the
file saved and haven't finished that project).

Let me know if you get it solved (I'm using ODBC to a cheap acess database).

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

Marius Kjeldahl

Very intersting stuff ... I think I will need finaly to try Zope my self
to see how it is. But I have one more question, why they decided to base
Zope on Python and not other language?

I use Rackspace.com which is certainly not as cheap as other hosting
providers but for under $200 you can get a fully dedicated 350 MHz, 64MB
RAM, 8 GB HD and RH 6.1. So, in the end you pay about 2 to 3 times what
another hosting provider has but it is your machine. You can install
whatever you please, configure it to your hearts content and never have to
worry about what someone else will say. Zope loves its own machine.

I have found their support to be great and they do a 24 hr turn around for
new accounts.

Worth every penny (twice the penny if it is for your company).

I think the best analogy is to think of ZSQLMethods, ExternalMethods, and
PythonMethods like "normal" functions in C:  they receive information via
arguments, and acquisition is always done via one of the explicitly-passed
arguments.  DTMLMethods/Documents are in some ways more like C macros:  they
grab information from the surrounding DTML context, without having to be told
what they can "see".

The analogy breaks down at the "call site":  Zope looks at the explicit
parameter lists and tries hard to match arguments to any parameters which are
not explicitly passed by the caller:  normally, it does this by looking them up
in the REQUEST object, *not* in the current DTML namespace.  Therefore, whenever
calling a non-DTML method (External/Python/ZSQL/...):

  * poke all interesting values into the REQUEST object before calling::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-call "REQUEST.update( { 'bar' : 42, 'baz' : 3.1415926 } )">
     <dtml-var foo>

    This version has the advantage of avoiding the "expression" syntax
    of DTML, but does require polluting the REQUEST namespace (may be
    an actual advantage if multiple methods use the same values).

  * pass the values explicitly, using positional arguments::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( 42, 3.1415926 )">

    This version looks most "natural" to a programmer, but is fragile WRT
    changes in the parameter list (changing the order of parameters on the
    method silently breaks this call).

  * pass the values explicitly, using keyword arguments for clarity::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( bar=42, baz=3.1415926 )">

    This version, which I prefer for any method taking more than one argument,
    says explicitly what it is doing, and therefore eases maintenance.

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985FA@pces.cadlab.it>

Python is quite slanted toward this kind of applications:
1) very clear sintax (many webmasters are not particularly fond of C and
Perl, like me...)
2) strong support for string management and a very good regular expressions
module
3) wide choice of modules for interfacing with web servers, mail servers,
database, etc...
4) ready-to-use modules for HMTL, Mail messages and XML manipulation
5) tons of good documentation, examples and a very active community
6) hard-rock core system and reliable modules
7) indipendence from the platform (Python runs almost everywhere. I'm
re-compiling it for my Z80-based microwave oven...;-)

Despite this, I think that the real reason why they decided to use python
was the terror to commit a mortal sin (like touching a Perl interpreter) and
the desire to live immersed in the light of the true Faith. 

I would have done the same...

This is great, some light at the end of a very dark tunnel.  One
question here:

How where you able to get strace to work?  I've been trying and it
either would lock Zope up or just return instantly.

Yes, we noticed that to.

Is this only when accessing via FastCGI or does happen when using
ZServer as well?

Thanks for the info.  If we find anything out I'll let you know.

My advice here is not based on work with Zope, but on years of painful RDBMS
experience:  I do *not* recommend storing large BLOBs in any existing RDBMS --
they aren't built for them, and generally make your life miserable when you
try.  Most of the reasons you would choose to use an RDBMS (performance,
replication, stability, searchability, etc.) don't apply when it comes to large
BLOBs;  you are still much better off storing the "BLOB" in a filesystem
somewhere, and then storing a path/URL to it in the RDBMS.

With Zope, BLOBs present another issue:  because they aren't standardized, each
RDBMS has a proprietary API for BLOBS;  the Zope database adapter therefore has
to have custom code for each RDBMS, making the BLOB code one of the likeliest
sources of weird, hard-to-reproduce bugs I can think of.

In short, *don't go there*.  Really, I'm serious.

Tres.

P.S.  If you *have* to go there, use the Python base64 module to encode
      binary data.

No such decision was ever made. When Paul Everitt and Rob Page founded Digital
Creations (a history I know only from Paul's and Rob's telling me, I could
well be out for lunch on this), Paul was getting quite heavily into Python
already. He convinced Rob that it might be a good language to base their
development on.

They then hired Jim Fulton, then already a very active Python contributor (he
hosted, if IIRC, the 3rd and/or 4th python conference or something). Under his
technical guidance software was developed that only in November/December 1998
came together to form Zope.

Many parts of what is now Zope, like Bobo (predecessor of the ZODB), DTML
Templates, Extension Classes and Acquisition where already Open Source, and
heavily used by the python community. When Zope came to be, all those parts
were mixed with things like Acquaduct (now database adapters and ZSQL
Methods), and Principia (now the web management interface and many of the
stock Zope objects like File and Folder), that were commercially sold by
Digital Creations.

So, python made Zope and its power possible. If you now decide that you want
to go and build Zope in a different language, you will first have to try and
build all those parts from which Zope came to be. And this will be pretty
hard, if not impossible. Pythons clarity, OO orientation, extensibility and
last but not least Jim's technical excellence with python will be greatly
missing.

I think it had to more with Jim Fulton's "zealos object-orientedness" than
that -  Zope is a system for publishing python objects on the Web.

I suggest that you negotiate with service provided over the terms of the
service agreements. You might find that they are more flexible than their
web pages indicate. Or you may influence them to change the standard service
agreements. I use CodeIt Computing and am happy with their service.

The implementation I sketched out a version of the Prototype pattern, I think. 
Exposing the customizable bits is more like a TemplateMethod:  this would play
nicely with Acquisition, perhaps::

  <!-- Inside the index_html method of a "folderish" ZClass -->
  <dtml-if custom_foo>
    <dtml-var custom_foo>
  <dtml-else>
    <dtml-var default_foo>
  </dtml-if>

The trick then becomes giving the manager enough information to know how to
implement 'custom_foo'.  My current hack solves this by cloning the default bit
as a starting point -- perhaps the factory could clone 'default_foo' as
'sample_custom_foo', or something?

Message-ID: <Pine.OSF.4.02.10003211815310.20006-100000@batman.tamucc.edu>

Based on previous e-mails here, I have read that Zope does not support
server-side includes.  Is there a way to get around this in reference to
an img src, as in the following:

<img src="myprogram?-action=gif&amp;yadda yadda yadda>


Basically what I have here is a page that includes other documents (maps,
graphs, etc.) via server-side-includes.  If there isn't any way around
this, then I may have to forgo Zope for now...too much of my system
depends on this sort of thing.

This has to do with Amos's article on using XMLDocument at xml.com:
http://www.xml.com/pub/1999/12/zope/index.html

The example for finding items to catalog doesn't work for me.  When I enter
getNodeName()=='entry' in the 'expr' field I get the following error:
 Error Type: NameError
 Error Value: Eval

I'm running Debian GNU/Linux (frozen), Zope 2.1.4, Zcatalog 1.0.0 and
XMLDocument 1.0a5.

Thanks for any help you can give me on this one.

Message-ID: <B059671903C6D211A0D500C0F0301C792B2714@kubrick.mop.no>

Adding a SiteRoot object to some folder upward from a ZDConfera topic
("Confera Topic" object) will break the topic.

It seems that when adding a message, instead of inserting a valid
message object, ZDConfera ends up adding a corrupt object. At one point
ZDConfera, when I tried adding a follow-up, duplicated the parent
message instead of adding the reply, resulting in a circular reference
that only a database restore would fix.

This is Zope 2.1.4, SiteAccess 1.0.1, ZDiscussions 0.2.0, on Slackware
Linux 2.2.

Here's the traceback.

I would like to know why the following happens, and what I can do to fix
it:

I have a ZCatalog instance in my root folder called Catalog. I have some
CatalogAware ZClasses that get added to it automatically.

The problem is, when I query Catalog for results, it only shows the
elements that were present the last time I clicked the "Update" button in
ZCatalog. The new elements are present in the catalog, but they don't show
up in the query until I manually update the catalog.

Here's the query code:


<dtml-in "Catalog(meta_type='Track', track_hasfile='on',
track_active='')">
  <li>
  <a href="<dtml-var "Catalog.getpath(data_record_id_)">/approve">
  <dtml-var "Catalog.getpath(data_record_id_)"></a>
</dtml-in>

Any help appreciated. Please CC me if you answer.

Here's the scenario that I'm dealing with (all of this works w/o Zope,
i.e. static content):

  - user starts at www.mydomain.edu (http)
  - user goes to www.mydomain.edu/internal which is secure (https) and
    requires a password for entry
  - all pages under www.mydomain.edu/internal are secure (https)

I'm having trouble getting this to work with out Zope-ified site, however.
What I would like is to have Apache handle all password authentication, and
I would like it to happen over ssl.  Is this possible at all?

Any help would be appreciated.

Just a few thoughts.

Simple workaround: make the id field unique. it would seem to me that
you could then use a try/except clause that tried to insert the data
into sybase, and redreate an id if it failed due to the id already
existing.

Additional options:
 o add a randomly selected letter (or two) to the numerical id. Now the
odds that any two servers, or a change in time, will obtain the same key
are extremely slim.
 o Randomize the order of numbers in the 'timestamp'

Combine these with the unique restriction above, and you should have a
_very_ scaleable, an relatively easy to implement, solution.

Subject: [Zope] Casting to a list
Message-ID: <38D91168.F163496@messagemedia.com>

Another question (soon I'll start answering more on this list :) - I
have a set of checkboxes with the same name that I iterate through
using dtml-in. However, when only one checkbox is checked, dtml-in
complains that a string cannot be used as input, it expects a
sequence. My initial thought was to do this:

<dtml-if "type(var) == type('')">
  ... (do not iterate)
<dtml-else>
  <dtml-in var>
    ...
  </dtml-in>
</dtml-if>

How can I either cast a string to a list w/o messing up an existing
list, or gain access to Python functions such as type() from a
dtml-if statement?

Zope in a sense replaces server-side includes with <dtml-var>.

What you need to do is upload the images to Zope in whatever folder
is appropriate. To do this, select "Image" from the create item menu
found at the bottom of your Zope "Contents" screen. Select the images
you would like to upload, and submit.

The images will then be in your object hierarchy.

You can reference them using either
  (1) Manual <img src="...">
  (2) Using dtml-var (the Zope way of doing things)

Say, for example, you uploaded an image called foo_jpg (Zope does not
allow dots in object names). You could reference it from any object in
the same folder as the image or nested folders using dtml-var

	<dtml-var foo_jpg>

Zope will automatically insert the height and width attributes and so
forth. To remove the border, you would use...

	<dtml-var "foo.jpg.tags(border=0)">

(I think)...

There are some interesting HOWTO's on this topic at zope.org.

I quess Zope is more "object-oriented" as it is based on an OO language.

OTOH, said OO language itself has been implemented in OO and non-OO 
languages (java and C) ;)

Probably the less flexible one ;) I don't know which.

There is currently a 2 Gig native (Zope internal) database size limit. 
This won't apply when you use external database or sore files in file system.

Zope has integrated a lot, so does PHP - you probably find most popular 
"other technologies" supported/supportable on both.

Probably Zope (this is a Zope list)

The one you know better :-p

I guess they are about the same. The one that will be used more will 
eventually be safer due to more eyballing.

Both can be configured to be insecure ;)

Howdy everybody.  Last night at the Bay Area Linux Users Group meeting I
announced that we are going to make ZEO Open Source and thus a
first-class feature of the Zope platform.  For more information:

  http://www.zope.org/Products/ZEO/

Some quick notes:

  o A first release for a very small, qualified group of testers will
happen mid-April

  o General release some weeks after that

ZEO (Zope Enterprise Option) turns Zope into a *distributed*
transactional object system, allowing people to add processors,
machines, and networks to scale their web applications.

It looks like Proxy Pass is the best way to go.  Can you use Proxy Pass with
SSL?  ZServer alone is not a choice because SSL is a requirement.

I'll look into something like this possibly being a feature.

It sounds like this is probably coming from an SQL database? If it is
modify the query you're using to sort on the DBML-side. If your
query looked like:

	select * from books

You would modify it. Having mutliple levels of order by varies from
DBMS to DBMS, but it'll look something like this:

	select * from books order by book_name, id

Or something to that effect.

Sorting using the DBMS is more desirable as well because the DBMS
is likely to sort it more quickly, with all its indicies and so
forth.

If you tell me which DBMS you're using, I probably know exactly
what you should do to your query.

Ihis didn't work, then?  Looks better than what I came up with, which, for the
list vs. string situation goes like:

<dtml-try>
  <dtml-in string_or_list_var>
   list stuff...
  </dtml-in>
<dtml-except>
  non-list stuff...
</dtml-try>

If you have a string with multiple values to split, use the _.string.split()
function, as...

<dtml-in "_.string.split(str [,separator])">

This will probably choke on lists, though.  Combine the two for a wholesome,
good-start-to-your day breakfast code. :-)

This is less of a Zope issue and more of a DBMS issue (which is why I
can answer it)...

There are two ways to get global unique ID's:
  - Have a unique ID server
  - Find a way two servers can come up with ID's unique to each other
    without talking to each other. This is a lot of fun, and is done
    by using the network card's ID number, which is statistically
    unique. Basically, if you use the computer's network card ID, you
    can generate statistically unique ID's (this, incidentally, is the
    MS SQL Server way[*])

[*] I in now way indorse MS SQL Server. Please do not flame me for
mentioning it; I know it's a peice of crap. :)

The former is more elegant, but the latter is sometimes more practical
for distributed systems. At any rate, there is no simple solution to
this problem (many companies have had major research into this area
with little results). Your best bet is to keep this out of Zope and
just set up a unique ID server.

Have your databases (Sybase?) establish foreign links to the unique ID
server. Then, write triggers that grab ID's when rows are insert. Say
you had two tables, on two servers, that need to have unique ID's.
You would omit their ID fields upon doing an insertion, making them
NULL. You would write a trigger on insertion for these tables that
would detect the NULL id field, grab the unique ID from the unique ID
server, and insert the row with the unique ID.

In very large environments with lots of data importing, this can be
a large strain on the network and the unique ID server. If this is
the case, be sure to have good bandwidth between the servers. And
as always, bigger servers means more performance. :)

The simple answer is: you don't need to cast. :)

Zope provides a solution: your specify in your multiple-select
a name like varname:list, and Zope will automatically cast it
into a list. That is, append the ':list' to your variable names.

Thank you for your input..I think I need to explain myself a little
better, however.  I have no trouble with a static image...the trouble I am
having is with images created on the fly.


For example, I have a cgi program (which I would like to continue residing
in my linux structure.....static pages I would like to be in
my Zope structure).  This program will generate a graph based
on the time units, and whatever particular data sets I pass as parameters
to the program.  So, the image can't be stored on  Zope, since the image
may be different each time it is brought up...for example, I have the
ability to pass the word "today" as a parameter...this means that
everyday, the graph generated will be different.  Is there a way for
Zope to respond to a cgi program that's being called as "img src" value?


Thanks,
Jessica

My understanding from a recent discussion was that it happens on all platforms 
with 32-bit ints regardless of weather they support large files or not.

does ZDB use longs internally and just some small part strangles it to 32-bit,
or is it something more widespread ?

Message-ID: <B059671903C6D211A0D500C0F0301C792B271A@kubrick.mop.no>

I use identity columns with Sybase -- the only problem I've experienced
is a tendency to occasionally "burn" ID values, resulting in gaps.

If you're not worried about non-sequentiality, identity columns are
generally not a problem. Do you anticipate crashes? I have run Sybase
for about a year, and never experienced a single crash -- meanwhile,
Zope has crashed and/or been restarted many, many times.

Aside for identity columns, here's an alternative scheme I used some
time ago with an  Access database (where, aside from DAO/ADO, you simply
cannot obtain the previously inserted "autoincrement" value, causing
problems for web-based forms): Create a table such as this

	create table Ids
	(
	  Id int
	    not null
	    primary key nonclustered
	)

Then create either a stored procedure (don't like 'em) or a Zope DTML
Method that will (a) get the lowest available ID, and (b) if the table
is getting empty (count < delta), then replenish the table with new,
unique values, starting at the ID you just obtained. (If the table is
empty when you start out, assume this is the first time the method is
run, and simply start with a seed of, say, 1.)

Because of transaction logic, IDs will never be "burned", and the only
gaps you will experience will come from IDs that disappear when their
parent records are deleted.

Hope this helps.

Hi there,

I'm trying to connect to an Oracle 7.3 database through Zope using a 'Z
ODBC Database Connection'.
It's giving me an error saying:
'Invalid connection string: gsmInfo'

I set up a DSN throught the Control Panel as follows:

Data Source Name: gsmInfo
SQL* Net Connect String: 2:
UserId: testowner

This is using the 'Oracle73 Ver 2.5' Driver.

I also used the '32-bit ODBC TEST' that comes with Oracle and this
connected to the database no problem after entering in a password.

Has anyone got any clues or suggestions to the problem.

Thanks in advance,

Michael Gannon.

So, you have a CGI script that dynamically creates an image as its
output. You'll either need to re-implement this using Python and make
a ZOPE product, wrap it using a Zope product (which seems the least
elegant), or just keep it out of Zope (probably the desirable). I
assume you're running apache and using Zope.cgi, so your Zope path
is

	http://yourhostname/Zope

Now, your CGI scripts are under:

	http://yourhostname/cgi-bin

You'll just want to reference the images just like you would in
normal HTML. Zope will not mess with an img tag, so if it points
to a working CGI script, you're ok.

Does that answer your question?

Subject: [Zope] Role weirdness
Message-ID: <m3em92zrw9.fsf@wacko.pdx.net>

I have a site containing some content users need to register to see.
The way I set this up was:

/premium/acl_users[GUF]
Using GUF to authenticate and assign users a role of
contentSubscriber.

At one point in time, I created a user defined role at the root level
of my Zope called contentSubscriber.

I then changed the security on /premium to require contentSubscriber
role to view or access content information.

Now, I can't seem to find any mention of a contentSubscriber role
anywhere in my Zope management screens OTHER than by looking at a user
through /premium/acl_users/userList.

None of the Find/Advanced... screens mention my contentSubscriber role
either.

The odd thing is that my access control scheme appears to work.  Other
than my random hourly crashes.

That doesn't look like a valid connection string. Usually, the connect
string is something like:

        user/password@sid

At least using the normal Oracle interface. SID, which I assume would
map to ODBC would be the datasource name defined in your tnsnames.ora
file.

You might try testowner/password@gsmInfo

Or consult your ODBC docs on proper connect strings.

Sure.  I'm using mod_ssl and apache 1.3.12:
My conf is like this:

<VirtualHost 216.17.170.666:80>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
</VirtualHost>
<VirtualHost 216.17.170.666:443>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
   ServerName imeme.net
   ServerAdmin mindlace@imeme.net
   ErrorLog /path/to/apache/logs/error_log
   TransferLog /path/to/apache/logs/access_log
   SSLEngine on
   SSLCertificateFile /path/to/apache/conf/ssl.crt/server.crt
   SSLCertificateKeyFile /path/to/apache/conf/ssl.key/server.key
</VirtualHost>

I have zope actually running standalone on port 6666.  Then I use
SiteAccess.
The access rule should look like this for you:

look for internal, then munge the result to be 0 if not found:
<dtml-if "1+(_.string.find(PATH_INFO, 'internal'))">
  <dtml-call "REQUEST.set('SiteRootBASE','https://www.mydomain.edu')">
<dtml-else>
  <dtml-call "REQUEST.set('SiteRootBASE','http://www.mydomain.edu')">
</dtml-if>

then you want to put a SiteRoot object in your root folder, leaving
everything as per default.

As long as your first links to /internal are written as https:// the
austhentification should be over ssl. The access rule makes sure any
dynamically generated URLs under /internal are written as https://

Subject: [Zope] Roles, Local Roles, and so on
Message-ID: <20000322213020.A16021@owl.rhein-zeitung.de>

Hi,

I have a question concerning the Role and Local Role system. Well, am I right
with the observation, that Local Roles are only locally assigned global roles?
For example I have an user "oandrich" which is globally just a member of Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to get
really local roles?

Bye, Oliver

emphatically yes- see my message to Erick Mechler re: httpd.conf help.
There are some complications with virtualhosting, because zope only sees
whatever it's listening to, so you have to have a different
<virtualhost> directive for every virtual host as opposed to just
letting zope handle virtualhosting.

phew.

I use a wrapper sql method called UserSettings.

Any calls to data are wrapped in a call to UserSettings eg.

<dtml-in UserSettings>
...
</dtml-in>

UserSettings SQL is : "select * from online where username=<dtml-sqlvar "_.str(AUTHENTICATED_USER)" type=string>"

The online table has columns for data (user name , etc) as text and memos  and permissions (is_super, edit_media...) as logicals
(True/False)

I use the returned information to decide whether an item is displayed or how it is displayed.

No, its a dtml-in for a ZCatalog.
Can I pre-sort the catalog for one MetaData field, and sort the dtml-in
for the other one?

Or are their any easy ways to modify the dtml-in tag to handle multiple sort fields?

Note that the version I posted has several rough edges:

 * It doesn't propagate the CGI environment to the child process.  We
   could fix this on Unixen by doing a fork() and some execve() magic,
   but then we lose the convenience of popen();  CreateProces() on Win32
   requires special handling, too.

 * It doesn't propagate the input stream some CGI's may expect to find.
   "Temp files and fork() and dup(), oh my!"

 * Win32 versions to use the win32.popen(), instead of os.popen().

 * The error handling is ugly.

 * It double-buffers results (which could get ugly if the CGI does
   weird stuff, or returns a really huge result).

In short, its a pretty ugly bandaid, recommended only for easing the CGI
withdrawal jitters. :)  Doing the Right Thing (TM) involves reimplementing a big
chunk of a web server, which is probably why Zope Didn't Go There already. 
mod_rewrite looks pretty sane by comparison.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A09A@express.sematech.org>

I have a dtml-method page that displays a table of values and allows the viewer
to delete on of them (using an sql method on the next page).  All works as
expected, but I noticed an odd thing:  when I used the back button on the
browser the table of values was not updated, but showed the old values.  This is
bad, because people will think their delete did not work.

How do I force a page update?  I checked the IE5 options to make sure it was
checking the date stamp on every visit, so I don't think it's a cache issue,
though I don't know enough about browsing to say it isn't.  Shouldn't forms be
re-submitted on the back button?

I'm sort of confused how this is all handled....

Environemt propagation after a fork wouldn't be too hard, and I was
kindof assuming punting on Win32.

There wouldn't need to be much, just catching errors from the Zope side
code, anything the CGI raises is it's own problem.

I strongly suspect that this is a symptom of a known (to me) incompatibility
between SiteAccess and ZCatalog.  If ZDConfera uses a ZCatalog to track
topics, it will not be able to retrieve them correctly.  I have a patch to
ZCatalog to fix this, but it hasn't been tested by anyone but me.  It just
replaces the resolve_url method of ZCatalog with one that doesn't reenter
ZPublisher.  If you're willing to test it, I'd be happy to send it.

Hi,

may be I am just to dumb or something like that, but Zope has to now who is
the owner of a certain document. This is for sure, but how can I get the owner
of a document from DTML or an external method? I read through the sources and
maybe I am just to dumb or so to find it, but I can't find any manage_* call,
that tells me how to do this?

I have to write a small DTML method, that finds all documents, that are
located in a givben hierachie which are owned by a certain user.

Bye and many thanks,

Please send me the patch. The problem does not seem to have anything to
do with URLs, but rather the objects indexed by the topic -- but I could
be wrong here.

Is there a way to modify ZDConfera/ZDiscussions to fix the problem,
without patching ZPublisher? I wouldn't want to break something else in
the process.

I think maybe the issue got clouded by the phrase, "server-side includes".
What you are asking for is not a server-side include:  you want to generate a
tag in Zope, something like:

  <img src="build_graph?units=hours&series_a=hit_count&series_b=load_factor">

This isn't SSI because the browser makes a separate request for the image,
after/while loading the page containing the tag;  SSI is massaged by the server
before the browser ever sees the text.

That said, it *is* feasible to build a parameterized image link, using exactly
this kind of syntax.  There are a couple of contributed products which do
on-the-fly image generation:

  * "gdchart":http://www.zope.org/Members/teyc/ZGDChart 
 
      "draws charts using data from your ZSQLMethod"

  * "TTImage":http://www.zope.org/Members/RainDog/TTImage

      Converts text strings into a GIF/PNG/JPEG images using
      TrueType fonts.

I may have even missed one -- check out the "Zope
Products":http://www.zope.org/Products page.

Without patching ZCatalog, you mean? Hmm.  Possibly.  If ZD* were patched to
use a subclass of ZCatalog which overrode resolve_url, that would work.
Here's the replacement resolve_url for ZCatalog:

    def resolve_url(self, path, REQUEST):
        """
        Attempt to resolve a url into an object in the Zope
        namespace. The url may be absolute (site-relative) or a catalog path
        style url. If no object is found, None is returned.
        No exceptions are raised.
        """
        pparts = filter(None, string.split(path, '/'))
        try:
            obj = getattr(self.aq_parent, pparts.pop(0))
            while pparts:
                obj = obj[pparts.pop(0)]
            return obj
        except:
            return

Yes, most browsers do this.  It's simply a result of their caching.

The only way i know of involves catching hits to the back button involving
JavaScript.  Not pretty, IMHO, nor terribly portable.

Either that, or, as some of our sites have, put up a message saying "DO NOT

Subject: [Zope] How do I get the owner of a document?
Message-ID: <B059671903C6D211A0D500C0F0301C792B2722@kubrick.mop.no>

If the object inherits from CatalogAware, you get a bonus method called
owner(), which you can call like so:

	<p>The owner of this document is <dtml-var owner>.</p>

If not, you can use the get_local_roles() method. You need to iterate it
-- best with an External Method. Like so:

	def GetOwner(self):
	  for Role in self.get_local_roles():
	    if 'Owner' in Role[1]:
	      return Role[0]
	  return 'Zope'

Add this External Method at top-level. Then, thanks to Acquisiton, you
can access the value in any document thus:

	<p>The owner of this document is <dtml-var GetOwner>.</p>

Hope this helps.

I have an application (Windows/DOS) that I want to re-write for the
web.  It is a data entry intensive application, with approx. 200 screens
for adding and updating a number of tables.  I am currently looking at
using PostgreSQL for the database.

Is this application appropriate for Zope?

Yikes, just noticed this one sat in my outbox unqueued :

Going back a month, just have to say thank you Chris.

It does work - I was getting the earlier error messages due
to being a bit ambitious and trying to display all of the 
images.

Just for the record, to get it to work :

1. Create a ZSQL method <ZSQL_SelectPicture> to extract the binary data 
   field ('picture') of one (1) image. That's the important part - one 
   single image.  Don't try to select several records for further logic
   processing.

2. Create a DTML method that returns nothing more than the 
   BLOB data from the ZSQL method, with the correct content type.
   Eg. 
  <dtml-call "RESPONSE.setHeader('content-type', 'image/jpeg')"><dtml-in
ZSQL_SelectPicture><dtml-var picture></dtml-in>

Accessing the DTML method directly will return the image.

This is stunning news.

Still absorbing this, but I think this will have ...interesting... ramifications for Zope in the marketplace.

From the Fact Sheet
"In summary, the ZEO architecture provides the power, flexibility and intelligence needed for the most demanding web applications."

and to think I wasn't going to check my email tonight.

I would imagine so... DC has written apps that handle intensive data
entry.. Zope gives you stuff like a security framework, a relational
database interface, a built-in object database, a document templating
language, undo, remote procedure calls from other machines, more.   

But the number of "screens" your application owns isn't really enough
information on which to provide a meaningful judgment.  Does your
application require delegation of authority?  Multiple security levels? 
A management interface?  Personalization?    Would it benefit you to be
able to run the app on multiple platforms without source code change? 
Does XML-RPC buy you anything?  Does FTP access to the ZODB buy you
anything?

Additionally, in the end a decision should generally take in to account
to how comfortable and familiar you are with a product.  If you're new
to Zope, Python, and OO, and you're under the gun to get this project
done and meanwhile you have 7 years of Perl experience, you may want to
seriously consider using Perl.  On the other hand, if you're curious
about Zope, Python, and OO, and you want to get some experience and
you're not tied to anything else in particular, Zope starts to look
really attractive.

Arghh... I should have been more clear, hopefully
someone else already has told you in the meantime,
but if not, the colons should be in the HTML FORM
fields, not inside the target DTML method.

That is, if you have check boxes or multiple select
form-input-elements, you would use something like:

<input type=checkbox name="mychoices:list" value="myvalue1">
...
<select name="mychoices:list" multiple>
<option>
...

Inside DTML, you would just use the name "mychoices" without
the colon. Something like:

  <dtml-in mychoices>
   <dtml-call "qryCAssign(user_id=_['sequence-item'],
                          client_id=client_id)">
  </dtml-in>

If qryCAssign() is a DTML method instead of an
external method, generally you would need to
prepend (_.None, _,... ) to the argument list.
That is, qryCAssign(_.None, _, user_id=.......)

Stable and functional.  It is being tested on several projects.

No.  These are very deep issues, especially the replication part.  If
this is important to you, I suggest using a replicated filesystem to
store the final FileStorage file, like Coda or Intermetzo.

While it would be a great idea for there to be failover and replication,
the issues are complex and without more wide spread use we really don't
want to start engineering a solution (one of the reasons we are open
sourcing it...)

IE will show a cached page, regardless of the settings, when hitting the back button.
If you were to type in the URL, it might actually get the page, but you can never be
too sure with IE.  Its cache is terribly misbehaved.  Try making the page uncacheable
with a Cache-Control: no-cache header.  To verify if this is the problem, hit
ctl-reload in IE (shift-reload in netscape) to force a reload of the page.

This should work (untested):

Some sort of transaction log would be nice. Not only could you track this

on my part.

Paul teased greatly last week with his announcement about a BIG
announcement he was going to make at BALUG. I was going to be out for the
day and not able to keep up with the mail but before I left I checked mail
hoping there would be news as to what it was. Alas no such fortune.

I get back and WOW! This is absolutely tremendous news.
Major, major thanks to all at DC, especially those that pulled the trigger.

I agree that this does set Zope apart from the others. It also set DC apart
from the others in their willingness to do a very good thing.

May DC be greatly blessed and prosper mightily because of the gracious
giving and contributions to the best open source web platform out there.
Once again mucho gracias.

This should be fairly easy to do by creating an external method that calls your
program, then calling the external method using dtml.

Just to nitpick, that isn't true. Zope object ids can contain periods, but it
makes it a pain to refer to those objects in Python expressions. -jfarr

Just for the record, I dont' use FastCGI and have seen Zope
die under the same circumstances; ie. by disconnecting the 
browser mid-download of a (usually long) page. Fortunately, 
that 'client' has been me via the administration screens, 
but it does seem like a rather trivial DoS. 
But it seems that this only happens with certain types of
pages - I'm not sure which.

Unfortunately, I can't remember if this was when we were using 
PCGI or Proxy-Pass, but it was definitely one of the two.

Hearing that others are now experiencing the same gives me
hope: this could explain the crashes that we've been plagued
with for months (though I fear any solution will come too late
to prevent our switch to an alternative platform).
 
chas

ps. Weird thing : the most stable Zope installation I have
    is on NT. It never, ever crashes, despite being the 
    development machine (I wouldn't say that load is causing
    my production server to die b/c it happens under low load
    too).

It seems that a lot of sites (including mine) have problems with Zope's
stability but somehow not many people reported the problems, and I am not
sure whether DC was/is aware of them. Our most useful Zope component right
now is a script that checks our Zope server every 5 minutes and restarts
it if it is down. I have spend many hours debuging but I failed to find
anything sustantial. I am under the impression (but nothing more solid)
that one problem might involve the interaction of the select call and
signal handling or the python wrap around the select call. No proofs
though. Unfortunately like you I failed to convince people in my group to
use Zope for more ambitious projects because of the stability problem.

It may also be due to people using the ZopeMonitor on Unix, which
restarts Zope if it dies.

Even better, it is a part of Zope! :)
From z2.py:
========================================

  -Z path
    Unix only! This option is ignored on windows.
    If this option is specified, a separate managemnt process will
    be created that restarts Zope after a shutdown (or crash).
    The path must point to a pid file that the process will record its
    process id in. The path may be relative, in which case it will be
    relative to the Zope location.
    To prevent use of a separate management process, provide an
    empty string: -Z ''
===========================================

Basically, add the option, along with the requisite options, and there
you go.

the problem is not in your query-code, i guess ..

IIRC, the catalog-aware zclasses are indexed automagically
when created, but not properties you set after creation. So
when you search for track_hasfile='on' , Zcatalog doesn't
have that property indexed:

You'll have to add :
<dtml-call reindex_object> in your Zclass Constructor method
( if you change properties there)

like this :

<dtml-with "Zclass_name.createInObjectManager(REQUEST['id'], REQUEST)">
       <dtml-call "propertysheets.Propertyshhet_name.manage_editProperties(REQUEST)">
       <dtml-call reindex_object>
</dtml-with>

-
Another possibility could be that you haven't added
track_hasfile to your indexes in Zcatalog.
If it is just a on/off-flag (which it looks like from here)
, add it as a field-index..


For better information, check out the excellent Zcatalog /
catalogAware HowTos on zope.org..

try

                relation='uncle'>

When you use the double quotation mark, it processes the content between
the double quotes as python code to be executed.  Since there is no
python code called bob, it fails.  Putting single quotes treats the
value as a string.

Hi there,

Thanks all for your help.
I got it working by keeping my old configuration in the ODBC Control

'gsmInfo testowner PASSWORD' as the connect string in Zope.

Message-ID: <38D9EA88.8BB86B9F@nipltd.com>

Hi,

A simple question, but getting a bit irritating...

How can I change the roles assigned to a user without knowing their password?

The form to do this has password fields which come up blank, and you can't submit the form without
filling them in.

I don't want to know what the user's password is anyway, I just want to change the assigned roles...
;-)

HSCH,

Chris

Subject: [Zope] Using a database connection from an external method
Message-ID: <38D9F99C.726D6D4C@funcom.com>

I'm still figuring out how to integrate stuff in and out of Zope, and
thanks to all the people who gave me the friendly advice that I should
stay away from storing blobs in databases (I kind of knew that already,
but guess I was to busy worrying about marshalling things in and out of
Zope).

Anyway, what I am trying to do now is create an external method that
will receive the REQUEST object with some fields AND the uploaded file.
This external method will insert a record into an SQL table and return a
unique ID which I will use for the filename for storing the image in the
local filesystem (I am not worried about LOTS of images in a single
directory - that can be solved by a more intelligent filesystem
[ReiserFS?] or by some clever directory indexing).

Assuming I am able to pull this off, it should be quite easy to pull the
image back in again using the LocalFS product or my own external method.

I guess the external method will be run in the same process and thread
as the Zope process itself, so I would really like to get hold of the
database connection from my database connection instance in Zope. 

From searching the lists, I have learned:

* How to get the ZODB instance using self._p_jar; but this is not what I
need. I need to get the database object for my MySQL database, not ZODB
* How to call ZSQL methods from external methods by simply doing
self.someZSQLmethod

The last method would probably work, but since adding something to my
database table really consists of a database insert, then getting the
unique ID returned and using this for stuffing an image into the local
filesystem, I would prefer to keep this all in the same External method.

So the question then is:

How can I obtain the database connection to the external database (the
"Z MySQL Database Connection" in my case)? And I do not mean the
connection to ZODB.

Thanks,

Marius Kjeldahl

i have a server running apache, with zope running on a specified port number. when i first created the documents i wanted to run in zope, i created a directory for images and the like in the zodb. after studying the structure of my site, i've decided i'd rather have the images directory in the server's folder system as opposed to the zodb. moving the images and such is no problem, however, the linkage from the documents to the images is going to be a big one. is there a way to set up something like a symbolic link from the images directory in the zodb to the images directory in the server folder system so i don't have to go in and manually modify the path for each image?

To be fair, there's not really a lot there...

I think everyone wants to know how to get onto the mid-april testing program! ;-)

You can specify ":list" in your checkbox code to typecast the input.

Here is a quick test. The list should display OK when one checkbox is checked.

<FORM method="post">
<INPUT type="checkbox" name="myList:list" value="First">First<BR>
<INPUT type="checkbox" name="myList:list" value="Second">Second<BR>

<dtml-if btOK>
  <dtml-if myList>
   <SELECT name="myList">
    <dtml-in myList>
     <OPTION><dtml-var sequence-item></OPTION>
    </dtml-in>
   </SELECT>
  </dtml-if>
</dtml-if>

<INPUT type="submit" name="btOK" value="OK">
</FORM>

This creates a user from python - nice, but doesn't solve my problem. I want
to be able to assign a property sheet of some sort to each user I create, so
I can store his/her local preferences on my site.

Does anybody have a clue on how to accomplish this?

Thanks for the suggestion, though.

Message-ID: <38DA05CD.7F089CCC@nipltd.com>

Hi,

I was thinking about putting my 'Changing Roles' problem into the collector as either a bug or a
feature request so I went and had a look.

It's REALLY hard to try and find out whether anyone else has done this before.
Not only is there not any real categorization of bugs/featrues within Zope (everything seems to be
'General') but neither the search or advanced search is documented.

Most irritating though was that it doesn't look like you can read problems unless they're been
solved, so although there were a couple of bug titles which looked like they could be what I was
talking about, they were all ***This item is under review*** so I couldn't check.

By all means flame me if I'm being stupid, but otherwise coudl someone help me out?

cheers,

Chris

Actually dots are allowed in object names. You can create a picture called 
"myPic.jpg" and insert it with <dtml-var myPic.jpg>.

However because of their special meaning in Python they make it more 
difficult to access objects in Python expressions from DTML.

Example, to access the picture title, you'd need to use :

<dtml-var "_['myPic.jpg'].title">

or (simpler but longer)

<dtml-with myPic.jpg>
    <dtml-var title>
</dtml-with>

Subject: [Zope] Roles, Local Roles, and so on


Hi,

I have a question concerning the Role and Local Role system. Well, am I
right
with the observation, that Local Roles are only locally assigned global
roles?
For example I have an user "oandrich" which is globally just a member of
Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available
below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders
of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online
admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is
no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to
get
really local roles?

Bye, Oliver


[RH]Oliver,

the current role system lets you assign roles from a certain object (you can
add them under the security tab).

You could also devise a method or a product that (manually) registers the
roles a user is entitled to (or already has, depending on the situation),
but that could get you turning in circles easily.

Rik

Would it work for you to create a folder for each user with id same as the
username?
You get a propertysheet with the folder for free. You could also make good use
of acquisition to display pages based on preferences.

The easiest option is simply to wait a bit til the PTK version is working. 
Or even help out yourself with this part of the code.  Otherwise, you can,
for example, create an SQL table (in gadfly) with the username as an unique
index and properties as other columns.

Okay, I've put this into the collector now (hence my complaints about the collector ;-)

I've got a proposal:

How about leaving the form as is, but if the password fields are blank, then don't change the user's
password?

I might have a look at coding this later today.

If I do, how do I get it into the CVS or back to DC in some other way that it'll make it into the
next Zope point release?

cheers,

Chris

I am not in a position to go into a testing program in mid-april,
however I think there are probably many of us who wouldn't or don't
currently qualify who would simply like observer status on a mailing
list or something. That way we can at least begin the learning process.
It also puts more eyes on the problem.

Your question addresses a fundamental lack in Zope.  Zope was developed
internally in a closed source fasion for years to address the needs of
paying customers.  These customers typically did not design applications
themselves, we did all of that.  Therefore, much of Zope's API is fairly
oriented toward specific directions and there are big gaping holes.

Don't let that discourage, you, there are big gaping holes in all
software.  We are working on a project right now to come up with a solid
undertanding of interfaces in Zope.  While this may seem like a simple
task, it is not, but we are working on it and we are making progress. 
Here, you have come upon a hole, there is a method that lets you do a
number of things in one call but there are no decomposed methods that
let you do finer grained tasks.  This kind of situation is common, not
just in Zope, but in lots of software where extensability is very
important.

Unfortunatly, this is a gnarly problem.  For example, if we decompose
manage_users() into a number of smaller methods, it would make sense for
us to re-implement manage_users() to use those methods.  But this
involves not only writing a bunch of new methods but also taking solid
proven code and discarding it for new code, based on even _newer_ code. 
This problem becomes almost nauseatingly dificult when you consider that
we could turn this process to all objects in Zope, Folders,
ObjectManagers, ZCatalogs... And while it may seem clear there should be
so and so methods to decompose to, we need to make sure we think hard
about issues like, should they be callable via XML-RPC?  Will this new
method reveal a security exploit?  etc...

I don't want to take the wind out of your sails, perhaps you could
suggest some improvments, all the code is there.  For now we are taking
small steps, document what is there, propose a framework for sensible
extension, and then fill in some of the gaps, and tear down some of the
cruft.  I will make a note of your question for when we get to security.

I totally agree, don't worry... no wind taken out of any sails ;-)

After all, Zope is free and there are plenty of (very) expensive alternatives that will have just
the same sort of problems.

Hope I can help at some stage :-)

Aye carumba, I haven't even been following this thread, not the most
useful subject line!

Ok, it looks like there are two issues:

1) some sort of FCGI issue which I do not have the capacity to reproduce

2) the same stability issue I am currently looking into.

The problem with 2) is that no one can reproduce it reliably (this may
not be true after I look at something someone sent me today, I'll keep
everyone updated) including myself.  I have pounded a half dozen
sandboxes with ab for hours and gotten nowhere.  No crashes.  Not a
single burp.

I'm, of course still looking into this, but I need more data from the
folks out there.

First of all, if you suspect that your Zope is dying and restarting
alot, run it in debug mode like this (unix only, sorry):

bash$ strace -f -e trace=none -signal=all python z2.py -D

See 'man strace' for the gory details.

obviously tune the parameters to z2.py to suite your needs.

What we are looking for here are SIGSEGV.  You'll probably see a lot of
SIGUSR1s, these are normal.

If you can get a SIGSEGV to happen reliably, _please_ let me know.

You'll have to roll your own form, and have it call manage_users on the user
object with the variable 'remote_user_mode__=1'.  For example::

 
<URL:http://server:8080/acl_users/manage_users?name=fred&submit=Edit&remote_user_mode__=1>

suppreses the password display (but it is still there in hidden input field!)

You aren't being stupid at all.  Here is the low-down on the Collector:

 * New items in the collector are immediately marked "under review" 

 * "Under review" issues can't be viewed until they get marked "in work"
   or some such, allowing submission of security-sensitive bugs without
   publicizing them to "black hats."

 * Most issues sit in the "under review" state far longer than the minimum
   time to triage out the security bugs; this is a lamentable corrollary to
   DC's short-handedness.

Fixing this problem would require adding to the Collector a new state,
"submitted", which then becomes the "show no details to black hats" state, and
sending off nightly emails of "submitted" bugs to the sucker^H^H^H^H^Hteam
member responsible for the Collector.  Moving the bug to "under review" should
then make it visible to outsiders in all its glory.

Hello everybody!

Please join me in welcoming Matt Burleigh to the Digital Creations
team!!

Matt joins us as our first (and sorely needed!) system administrator.

From Matt's man page:
"""
I call beautiful and historic Fredericksburg, Virginia my /home.
Fishing, hunting, and reading civil war history are my hobbies.  Don't
tell anyone but I've taken many tech support calls from a boat and even
lost a cell phone in the lake once.

In 1983 I got a 1200 baud modem for my 64k IBM PC and it was down hill
from there. Sometimes I feel like I spent all of my life in front of a
computer. I started the first BBS in the Fredericksburg area and a quite
successful one. Eventually becoming Central Virginia mail hub for
FidoNET and sucking Usenet newsgroup feeds off of a satellite dish then
divvying it up for the local area SysOps. Those Usenet feeds were from
this thing called the Internet, which took me by suprise in 1994. At the
time I was running a small computer sales and service shop in the area.

Once I realized that BBS's and RIP Script (a graphical language for
BBS's that was going revolutionize the online world, ha!) wasn't going
to make it, we switched our dial-up modems to direct connections to
ISPs.

In 1996 a friend of mine introduced me to Slackware Linux. This crude
operating system really intrigued me and I found it to be an exciting
new challenge. A couple months later I began selling used machines with
IP masquerading and firewall setups. Soon after that, I convinced a
customer of mine to switch from the ever failing Windows NT v3.51 to
Linux. The system ran for over 6 months with not one problem or required
reboot. I was hooked and swore never to install Windows NT again.

You could try:
<dtml-call "RESPONSE.expireCookie('main_counter'">

which might work.

Hello all:

Not sure if this has been asked before, probably yes, but haven't been
able to find anything yet.

Does any of you has been able to print from a Zope application to a
printer attached to the same machine where Zope is running, in my case
it's a Red Hat Linux 6.1 box.

I need to print from Zope with a specific printing format (like
invoices, receipts, etc).  This will be done on always the same Intranet
and printing will be controlled from the Linux spooling system.

If you can copy your comments to me by email besides the mail list, it'd
be great.

,Any help is appreciated, thanks in advance.

I am not usre what you need to do. The cookie name is SassionUID. If you
need to delete something from the FSSession data use FSSession.delete
like:

<dtml-call "FSSession.delete('main_counter')">

you can expire the cookie by ... reading Chris followup email (just

Message-ID: <Pine.LNX.3.96.1000323155356.11696K-100000@marvin.nipltd.com>

My saga with the standard_error_message continues ;-)

I'm trapping 404 errors for missing pages, checking the intended URL
against a list of URLs which have moved to new locations and returning a
link to the new location as part of the error page.

What would be useful would be to automatically redirect to a new URL if
it occurs, but this is proving a problem. I've been using
RESPONSE.redirect() as this has proved useful on other pages, but on
standard_error_message this doesn't appear to have any effect - even when
the entire contents of the error page is stripped out and replaced by just
the call to redirect().

Is it possible for standard_error_message to handle redirects (in which
case, what else do I need to do?) or is there another way to go about
this?


Thanks in advance.

John

Subject: [Zope] records form variable type
Message-ID: <wksnxh8xai.fsf@email.aston.ac.uk>

I have been using the records form variable type, but believe there
may be a problem with it. With most browsers all appears OK, however some
browsers (e.g. Mozilla) may return form elements out of order. What
this means is that when trying to use the records type their is no
guarantee that the different elements of a single record will be sent
consecutively and therefore the records objects will not be correctly
constructed by Zope.

I would like to know if this is the fault of browser or if this is an
issue which excludes the general use of the records type. If the
latter what alternatives would be recommended - I would prefer not to
have to create unique form element names as it would add a fair amount
of complication. 


What guarantees can be safely assumed about data arriving from a form
- for example if you try using the list type is the order in which the
components of the list guaranteed to be the same as the order in which
the respective form elements occur in the document?

i'm getting some funny behavior using a (separate from Zope's)
ZODB from External Methods.  after much thrashing, i've got my
application working.  however, every so often, when i click 
on a submit button that invokes an External Method, i get:

   Could not lock the database file. There must be another process
   that has opened the file. 

the odd thing is that if i click the browser "back" button, then
hit my button again, it works.  occasionally i need do this
back/resubmit thing more than once, but usually once suffices.

smells like a race condition to me.
has anyone else seen this, or have an idea how i can avoid it?

http://www.reportlab.com/ may be what you need.  It's in Python, so it
should be easy to hook up to Zope, and it outputs PDF which can then be sent
to lpr for printing.  Since RH uses Ghostscript as a print driver the
generated docs should print fine.

I would favor making it like the HowTo list; where you can organize by
title, date, author, and reverse them. The code should be a basic
copy-paste with slight modifications operation.

Just wondering if anyone has thought about personalization
services based on Zope ? 

The most obvious/traditional approach seems to be :
1. Acquire user information (via forms/surveys/transaction-histories etc)
   and store in RDB. 
2. When the user comes to the site (and either logs in or is identified 
   by IP or cookie), query the RDB for customized content or appropriate
   products. 

OK, no magic there. But it's not very scalable in terms of :
a) Load. We can keep shoving Zope servers on the front end
   but the RDB is going to get hammered if this has to occur
   for each and every request. 
b) Development. A more object-oriented approach would be nicer.
   eg. Personalities with behaviours and properties. 
   Could a pool of persistent personalities be left floating 
   around ? (No, this is not an early April's fool) 

A while back (1997) I saw Broadvision and didn't really appreciate
what they were doing. It seems that they've really improved a lot
since then but I can't get my hands on their software (not for free
anyway). So, I'm wondering if anybody has experience with it and 
can enlighten a heathen on key features we might wish to, er, 
'appropriate' in Zope systems ?  Or is it, like Vignette and Netscape
ECXpert, nothing special and you're basically paying for the 'knowhow' ? 

Thank you,

Message-ID: <002b01bf94e6$968a7af0$f2381bd8@LIPS>

hello:

i'm using Zope 2.1.6 and LocalFS 0.1.7.  when i try to view an image via a
LocalFS object i get an exception in OFS.Image.py at line 187:

last_mod =int(self._p_mtime)

the error occurs the *first* time i try to access a specific image with a
recently launched browser.  accessing other images or subsequent hits to the
troublesome image in the same browser do not cause the problem.  subsequent
hits in the same launch of zope from a fresh browser on another machine
causes the exception.

having modified Image.py to catch the exception and dump some information i
see that self._p_mtime is None.  i've looked around but cannot determine
where _p_mtime is defined or how it is supposed to be set.

i see this method in Image was re-written after Zope 2.1.4.

similarly, accessing a .wav file via LocalFS causes the following message:

2000-03-23T16:27:13 ERROR(200) ZServer uncaptured python exception, closing

the wav file is delivered to the browser correctly.

as a quick fix to the Image problem, i catch the exception, set last_mod =
0, and continue.  this does not seem to have any ill effects.

There was a CVS Checkin today for this problem.  You might want to check

Subject: [Zope] ZWiki comments
Message-ID: <38DA502B.B20E8928@texoma.net>

For a previous message I posted to the list I was prompted to place a
comment in the associated ZWiki.

I went to the ZWiki to comment and played with the "Sandbox" before
posting to learn a few things. From the things I learned here are a
couple of comments I wanted to throw out. I know some of these run
counter to the thoughts of the Wiki community but they are concerns
nevertheless.

The nature of Wiki is very unsecured. This is for better or worse. I
know the ZWiki on the Zope site does require logging in before editing
which helps but does not eliminate the potential of malicious or
accidental editing.

Anyone logged in can do any kind of editing they wish on a page. They
can erase all text. They can insert, delete or otherwise modify comments
or content made by other people. These things can be positive or
negative depending on the goal or intent of the page.

I think editing a page is more applicable to stable open content than it
is to a forum oriented page.

Examples.

If Zope's documentation was managed by ZWiki in a secure manner then a
community member could make corrections of typo's or legacy information
like references to Principia, etc. The submit button could either be a
"Submit for review" or if really trusted "Change". I know this
duplicates somewhat what CVS does. Once again depends on goals.

If the page is forum oriented, i.e.: an on going conversation like a
bulletin board and such then it is more appropriate to "Add comment"
than to "Change page". This would present the user with a cleaner
interface and a clearer idea of what they are doing. They would not be
presented with the entire contents of a page so they could merely append
a comment on the end.


If the ZWiki on the Zope site starts getting busy we run into other
problems. The problems especially affect a forum oriented type page.
Just to learn I opened up the "Sandbox" in a new page, I then open the
"Sandbox" again in a new page. I edited the first and submitted and then
edited the second and submitted. The first was successful. The second
fortunately got an error message. I say fortunately because it did not
overwrite the previous submission.

In a busy forum or BBoard multiple people getting errors would be a bad
thing. If in a forum oriented page an "Add comment" button was available
then the conflicts and errors would be avoided. This would also enable
ZODB's transaction mechanism better with each comment being an object
associated with the page.

This would also be more secure in that people would adding their value
and not altering other peoples.

On Philip Greenspun's site  http://www.photo.net  the BBoard's are
somewhat integrated with email. You can subscribe to a bboard and
receive email for the added comments. This is a nice feature. Their
implementation is quite inelegant and could be improved. Zope/ZWiki
could shine here. This allows user to choose how they want to view the
messages, either through the web or via email.

Just a few thoughts to throw out to the community.

Actuatly, there may be one other quicker method to do this.  You can somehow
(i haven't tried this) compile php into a stand alown executable.  Then you
could then have an external method do a shell call running the php script.
Another interesting thing you could do would be to make a zope product that
stored php3 code, and then called out to php to parse it.  This might not be
a bad way to allow clients to have their own maintainable php3 scripts up
on the web without giving them ftp or shell access.  hmm..

I was thinking of a general simple caching product for Zope, to use in
conjuction with FSSession for high load sites. A simple implementation is
to use an in memory python dictionary to hold marshalled or cPickled data.
Since the access times are fast we could use the asyncore classes that
come with python to achieve really high rates. The cache contents can be
served from a socket or a named pipe. A more difficult but more efficient
way is to use shared memory for IPC. As I don't expect two clients to
connect simultaneously with the same user id, write conflicts will be few
(I suppose writes will be few too).

In our environment I have found FSSession to be very fast, probably
because the OS caches files. If someone complains about FSSession's speed
I will code the caching product.

This was also posted to the ZEO/ZWiki at

Would there be any potential for allowing people who are doing
development only, not deployment stage, into the beta program? Using ZEO
could change the way I design the app. At least this is a thought from
what I read in the description.

I am very interested in learning the ZEO architecture and capabilities
but am only in a development phase. In other words, I will not be
offended by crashing or data corruption as I am in total control of the
system, access and backups, etc. I thoroughly understand this is a work

Just a thought.

On Zope, I created a new ZClass, EBook which is Subclassing, CatalogAware,

I created an instance of EBook which id is 'aid' in a Folder called 'new_test'.
It works fine in Zope except I cannot use my writeData method of my EBook
class because of the following error: 

Error Type: IOError
Error Value: [Errno 13] Permission denied: '/home/oscar/data/test_out.jpg'

I work with Linux and all users have the right to write in /home/oscar/data'.
I even tried to run the method from the interpreter, just changin
f.write(self.data) to f.write('arbitrary string') and it works fine.

I also tried to use the debugger to understand where I am wrong.

Or even better, a generalized version - so you could serve perl and php and
python cgi  scripts transparently from zope.  That's be pretty cool actually
- migrating our old sites from php to Zope would be trivial.  

Of course, it'd be much slower than having PHP3 compiled in to Apache.

Subject: [Zope] ZEO app architecture options
Message-ID: <38DA5AD1.EE6A264B@texoma.net>

Hello,

In light of ZEO becoming open source, I'm still extremely excited, I
want to revisit some questions I threw out in a previous thread about
Zope's scalability.

Can I architect a website like this using different Zope Storage Servers
for the various directories or 'would be' tables in an RDBMS? Yes, I
understand the impact of the OS filesystem concerning ZODB size.

Say for example I have a large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5+gb directory which is reasonably
stable updated monthly.
ZAuto/manufacturers isn't as large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.


Also, when comments are made about Zope's ZODB or ZSS not being
appropriate for heavy write apps, does this refer to apps doing
"updates" on objects or doing "inserts" or both using SQL terminology?

Would structuring an app like above help in write situations?

I am trying to determine the desirability or necessity of an RDBMS for
my idea. I like keeping it in Zope if reasonable and ZEO can definitely
help. If need be I'll go to an RDBMS for certain data.

Thanks for any help or clues.

As much as I appreciate the desire to get at ZEO early, we have to
balance that with our limited resources internally.  We're taking a
conservative approach to getting it out the door, rather than just
dumping code and telling people they're on their own.

Hopefully everyone can appreciate this.  Unfortunately we're taking a
lot of flak, for instance, for not releasing Tracker.  I wish we had
unlimited resources, but that's just not the case.  As everyone in the
Zope community will probably agree, we need to do a better job and not a
bigger job.

This isn't necessarily true.  Zope caches objects, and the scenario you
describe is well suited to the caching strategy.  (That is, a user is
probably going to come back again within a minute of their previous
request.)

Compare this to an RDBMS strategy where state is always being retrieved
on each request.

The PTK membership model allows arbitrary extension of methods and

Sorry, I forgot that I hadn't uploaded the text of the FAQ.  My network
connection was horrible yesterday (I'm in a hotel in the Bay Area right
now).  I'll upload it in a moment.

You'll need to write some software in Python that will interface with
Zope for printing to your local Linux printer. In general, this isn't
something one would normally go about doing.

Why not use something like SWIG (I don't know much about it, just a general
idea on what it does), to link the interpreter to python, and then make a
Zope extension like <dtml-perl xxx> to call it? Then you could probably get
the perl/PHP scripts into the ZODB, and therefore get cached, making it even
faster..

i think you need to set permissions to execute cgis within that
section, ie. put

Options ExecCGI

into your <VirtualHost></VirtualHost> section

Subject: [Zope] Troubles with SQL queries
Message-ID: <Pine.LNX.4.10.10003231313390.10023-100000@odeon.net>

Heya folks,

I've got an SQL query that looks like the following:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.date, gigs.start_time

This works fine.  The '/'s indicate that a single line continues, in the
ZSQL method the 'and gigs.date >= etc." part is on one line.

I'd link to be able to change the values the query is ordered by based on
the link used to access it.  Something like the following:

http://foo.bar.com/Zope/query?first=date&second=start_time

Towards that end I made the above look like:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.<dtml-sqlvar first type=string>, /
    gigs.<dtml-sqlvar second type=string>

When I test the ZSQL method it shows the SQL used as:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "2000/03/23"
  order by gigs.'date', gigs.'start_time'

Note the 'date' and 'start_time'...  Because of the 's the query does not
work.  

Is there a way to not have the <dtml-sqlvar> tag return the 's to MySQL,
or is there another way I should be trying to do this?

Thanks for the help,

Jeff Robertson

Subject: [Zope] How do I pass parms past a redirect?
Message-ID: <38DA80A9.411DFC15@sage.att.com>

i'm building an app that requires me to connect to another
server in the company to do employee authentication.
one connects to that site, passing a return URL.
it verifies the employee, sets a cookie, and redirects
to the URL you gave it.

so, in a document i want to protect, say, ChangePerson.dtml,
i've got something like:

<dtml-if "REQUEST.cookies.has_key( 'attESSec' )">

	...regular actions for the page...

	<dtml-call "RESPONSE.expireCookie( 'attESSec' )">
<dtml-else>
	Missing attESSec cookie!
	<dtml-call "RESPONSE.redirect(
'http://othersite/cgi-bin/authenticate?retURL=http://mysite:8080/ChangePerson&sysName=foo'
)">
</dtml-if>

note that the URL i redirect to expects two parameters,
retURL says where to return, and
sysName is an application name given when
i registered to use their services.

so far, so good.  the problem is, my document expects to be
called with some parameters passed, like:

	<a href=ChangePerson?hrid=1234567&name=garry>Change</a>

now, i can't encode these parameters in the retURL
i pass the other site, as i get a "malformed syntax" error.

so, my question is, how do i make this information available
to my script on the return?  do i set a variable in the container?
set a cookie?  or is there some better way?

to broaden a bit, how does one pass information around in general?
so far, i see several methods, for calling:

External Method: piece of cake.  real live arglists, like god intended.
DMTL Doc from form: form variables, mixing hidden vars in for other
stuff.
HTML links: cgi-style syntax, leads to ugly URLs.

is this the right way to do things, or am i missing something?

Subject: [Zope] xmlrpc authentication woes
Message-ID: <38DA8147.3E2F3325@boi.hp.com>

First, let me say I have patched my xmlrpclib.py to support
authentication; that isn't the problem.

Overview:
I have a folder, 'Administration', which requires manager login to
access. In this folder is a subfolder called 'MachineTracker'. In this
folder is a collection of ZSQl Methods, DTML Methods, and DTML
Documents. What I want to do is to connect to the server via XML-RPC,
and make use of the ZSQL Method for inserting data into the database.

Problem:
When attempting this from python in XML-RPC, I get a 401 Unauthorized
error. I can access the folder, and other methods, such as index_html()
and objectIds() with no authentication issues. 

Any ideas?

(please cc me here, this isn't my subscribed address)
TIA, Bill

 You can use one of the Session products (SQLSession or FSSession) to
store arbitrary per session info (even Zope objects) on the server. It is
probably the cleanest solution.

yellow,

As I was trying to send an attachment via Zope to whatever@somewhere.com i
wanted the dtml-boundary tag to do something like this:

<dtml-boundary type=application/octet-stream disposition=attachment
encode=base64 name="_['file.filename']">

but I just can't get this to work... the only way it works is to use the
attribute   name=file
The result is an attachment file.dat
I want Zope to send the attachment with the real filename.

HELP???

Use the handy dandy Python range operator (generates a list of ascending
integers of a specified length):

<dtml-in "_.range(noOfTimes)">
  <input type="text" name="...

A simple question, how can I determine the Owner
of a ZClass instance (or any Zope object for that matter)?

My users create instances of a Seminar ZClass.  I did not
create a SubmittedBy property (which I would fill from
AUTHENTICATED_USER.getUserName()) thinking that I could
easily extract this from the Owner role.  I just can't
see how to do it.

I have run into this problem before.  Floating about on the ZOPE site is a
patch for the MIMETools, which addes a few *_expr attributes, so you can replace

name="_['file.filename']"

with:

name_expr="_['file.filename]"

I have just written my own tag product (may or may not be allowed to release..
we'll see :)  I understand now why this is so.  It seems that, so far as the
product is concerned, there is no real way to tell the difference between a
string and an expression.

If I am mistaken, I would dearly LOVE someone to point me in the right
direction.  I currently distinguish vars and strings by if they have 's around
them, and expressions are attrib_expr.

But I digress.... the patch is your friend.. It is on the ZOPE site (sorry I
can't be more specific, but a quick search will find it.)  I have used it
myself, and know it works.

Message-ID: <000f01bf9521$065bc480$2aac8ec6@hikari.anu.edu.au>

I have a container ZClass Person.  Person has a (string) property
CurrentPosition which gives the id of a ZClass instance contained
in Person.  Example:

   DarranEdmundson (Person)
       bsc_degree (Degree)
       phd_degree (Degree)
       fellow     (Academic)
       fujitsu    (employment)
       vizlab     (employment)

where DarranEdmundson.CurrentPosition = "vizlab"


I am having problems accessing the CurrentPosition object
in a pythonMethod.

list = []
for person in self.objectValues('Person'):
     position = _.getitem(person.CurrentPosition)
     list.append(person.LastName, position.anyProperty))


I can do it in DTML via

<dtml-in "objectValues('Person')">
<dtml-with "_.getitem(CurrentPosition)">
   <dtml-var LastName> <dtml-var anyProperty>
</dtml-with>
</dtml-in>

I think the question really comes down to: how does one
achieve <dtml-with name> in a pythonMethod?

Subject: [Zope] how to get the fields returned SQL method
Message-ID: <86ln39meyg.fsf@marcelle.revolink.com>

Hello,

I'm trying to get a list of fields returned by a dynamic SQL query.
I've found a howto telling me to write something like :
	<dtml-in SQL.names>
	<dtml-var sequence-item>
	</dtml-in>
But it doesn't work : I get the error "Attribute Error : names".
I've tried with .items, .keys and .fields too.

I'd like to do the same for an LDAP query.


Any idea ? I think it's very useful and that an easy way exists but I
can't find it.


Thanks,

EB.

Message-ID: <Pine.BSI.3.96.1000323191423.15163E-100000@twirl.bitdance.com>

OK, so I read the Advanced Catalog Search HowTo, and I am left with
a couple of questions.  I'm concerned here with "or"ing the searches
on two fields.  The first question is, once I do the OR is the
result (which may be close to a thousand records) cached?  Otherwise
I don't think this is going to work.  Even if it is cached, I'm
thinking it may not work.  Is there any way to do an OR without
loading both result sets into memory?

The other question is, when I do the OR, how do I reduce the
composed list to just unique records?  The HowTo seems to just
do a sequence join, which would leave me with duplicated records
for those items that matched on both search columns.

Well, since the SQL will return a list, firsly you would have to index it...
also, .keys et al are Python stuff, so...(untested)

<dtml-in "SQL[0].keys()">

might be more what you're looking for.  Or...

<dtml-in SQL>
  <dtml-in "keys()">
    <dtml-var sequence-item>
  </dtml-in>
</dtml-in>


should iterate through the keys of each line of the returned table.

ZEO is transparent to the application, it is a _singular storage_
meaning that all the issues of multiple databases still apply, re, they
are not yet supported.

What this needs is the ZDBF (Zope DataBase Framework).  This is a layer
that sits above ZODB.  Currently, ZODB takes care of all these issues
(or punts on them) when really a higher level abstraction should handle
multiple database issues (including any future extensions to the
Relational/Object model).  Obviously, this is a big task.  See paul's
email about resources. ;)

First, keep in mind that to a certain degree, all databases are
sensitive to the high-write issue.  ZODB is more sensitive because it's
conflict resolution is optimisitic.  FileStorage is also sensitive
because of the  inherent behavior of filesystems, and ZEO is sensitive
because for every object written, an invalidation message must be sent
to all other ZEOs so that they are given the chance to invalidate the
object in their cache.  This also increases chances of collisions
because the Time To Write a record is extended for varous reasons
(network delay, invalidation delay, etc...).
 
> Would structuring an app like above help in write situations?

Not without ZDBF.  Multiple database support would allow you to use
different, less write sensitive storages like a RelationalStorage or a
BerkeleyStorage.

Do some benchmarks, ZODB is very fast if you are a little more clever
about how you change your objects.  If you need more write intensiveness
go relational.

One doesn't.  Instead one uses local variables, as you did with 'person'.
Your solution is almost complete, actually, and should work if you replace
'_.getitem(person.CurrentPosition)' with one of the following (I'm not sure
which, you'll need to experiment):

person[person.CurrentPosition]
getattr(person, person.CurrentPosition)
person.aq_acquire(person.CurrentPostion)

Sorry I can't be more specific.  In general, though, any place you would use
dtml-with in DTML, you set up a local variable in PythonMethods.

Cheers,

Evan @ 4-am & digicool

Message-ID: <200003240350.AA11082@rsphy9.anu.edu.au>

I recently took the site I have been developing online
and have been beta testing with several users.  I
have a problem which is preventing a user from
viewing his home page; any attempt I make to isolate
the problem hangs Zope, stops anyone accessing
my site, and requires a forced unix kill.

The user's page is:
   http://rsphysse.anu.edu.au/optics/people/jdl124

Users are implemented as a Person ZClass.  One
of their contained objects is a PublicationFolder
ZClass, itself a container class for Journal ZClass
instances.  So above:

optics (folder)
   people (folder)
      jdl124 (Person)
         publications (PublicationFolder)
             article1 (Journal)
             article2 (Journal)
                .
                .
             article69 (Journal)


jdl124's home page is dying when it tries to iterate
over the results from a search of the ZCatalog publicationCatalog.

The problem isn't in the publicationCatalog however, the following DTML snippet locks up my Zope completely:

<dtml-with publications>
<dtml-in "objectValues()">
    <dtml-var id><br>
</dtml-in>
</dtml-with>
</dtml-with>

I can deal with this during solo testing but my users' budding confidence in the system I have created
has been mildly rocked by this situation.  Needless to say, jdl124 is none too impressed.  Any help
you can offer is most appreciated.

Cheers,
Darran.

Subject: [Zope] DateTime Feb 29 error just in Netscape 4?
Message-ID: <Pine.BSI.3.96.1000323232658.15163F-100000@twirl.bitdance.com>

This is a bit odd.  I have some image objects that display fine in
IE 4, but in Netscape 4 I get a Zope error

Invalid Date-Time String
Tuesday, 29-Feb-00 17:53:59

The traceback ends with DateTime.py, line 848, in _parse.

Is this a Y2K-leap error, or is something else going on here?  I've
checked two of these images and in both cases the date it is
complaining about is on the 29th.

And why only Netscape 4 and not IE?

I think you want this, which (it claims) generates PDF documents within
zope.

http://yyy.zope.org/Members/gaaros/ZpdfDocument

Then you just print it however your clients are already printing.

--------------11C1869DF092DB44C388B170
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

Assuming you are just going to be using linux this shouldn't be _too_ hard.

You probably would want to firstly use the http client module in python
(not sure exactly what it is sorry). Which could download a html page which
is generated by Zope.

The with the html page you can make a system call to "html2ps temphtmlfile temppsfile;  lpr temppsfile -Pprinter". Python has the ability to simply call 
external program (i think it is os.system( ) ). Of course you could find/write
your own html->ps and printing code but when you already have html2ps and lpr
I wouldn't really bother.

Now if you wrap all that up into an external method which is called when the 
print button is pressed it should be quite acceptable.

Is this the type of thing you want or am I off in another planet?

How do I get it's contents if I only know it's ID??

<dtml-var id> returns string value for id
<dtml-var "id"> returns <Python Method object at 864c500>

So, stupid question.

HOW do I get the real document contents???

Why not generate a PDF file on the local file system and then print it

just my 2 cents...

I think a translator should implemented using a flag in dtml-var:

syntax: <dtml-var VARIABLE translate> and <dtml-var VARIABLE 
translate="de"> for example.
Short form: &dtml.translate-VARIABLE;

By default it chooses the root folder's (or even Zope's?) language setting, 
but the programmer can also choose the language. This syntax is very 
similar to the "missing" flag. This way you do not a separate phrasebook 
and word translator. All that is in the background....

Then there is a generic translate product which handles all the translation 
stuff and administrates the languages. One can easily drop languages into 
the product, by installing simply the dictionary for this language into 
some standard location and specifying some admin info.
I think that would be the cleanest way to implement ZIP.

What do you guys think? Comments?

Stephan

I tried sticking <dtml-var get_local_roles> in a dtml document and got a blank list back even though
I know I've got some local roles.

Also, where did you find out about this? I haven't found it documented anywhere...

<dtml-var "AUTHENTICATED_USER.getRoles()"> is also not too useful since it only returns roles where
the user object is defined, ie no local roles...

What am I doing wrong?

References: <86ln39meyg.fsf@marcelle.revolink.com>

Okay, a lot depends on what your query is returning.

If 'names' is not the name of a column, then ignore the rest of this message ;-)

If it is, then try the following:
<dtml-in SQL>
 <dtml-var names><BR>
</dtml-in>

- If 'SQL' returns a single row and 'names' is a single-valued column, then it should display the
value of names.
- If 'SQL' returns multiple rows and 'names' is a single-valued column, then it should display the
value of names for each row returned on a seperate line.
- If names is a multi-valued column then you should get something like
  [...,...,...]
  for each row returned.

cheers,

Chris 


If names is a single-valued column then the following should work

I experienced this as well also on Netscape (but I didn't try with IE)

Did you create the images on Feb 29th? I think I did and made the problem go away by re-uploading
the images.

This is a bit of a worry though, anyone got any ideas what's going on?

Hi Chris

I wrote Amos for exactly the same thing and here is his answer:

...
This is a Zope error. I was working with a development version of Zope
which didn't have the error. The error is fixed in CVS and should ship
in the next release of Zope. To fix the error add this line near the top
of your lib/python/Products/ZCatalog/ZCatalog.py file.

from DocumentTemplate.DT_Util import Eval, expr_globals

This should work if 'id' is what appears in the management view, etc...
What do you mean by string value?

Hmm, are you sure you're not trying to include python methods rather than DTML documents or DTML
methods?

Try:
<dtml-var "id()"> if there's not another reason why this isn't working...

Provided that ID contains a string representation of the id of the

Hmm. That's not what happens for me. I get something like:

[('admin', ['Owner'])]

How do you know you've got some local roles? Also, is this a DTML document or
DTML method, because methods seem to acquire the roles from their container.

> Also, where did you find out about this? I haven't found it documented

It's all in AccessControl/Role.py.

IMO the documentation is just a good place to figure out where to start reading
the code. ;)

Hi

  I've found two banners product under Zope site. My
question is: how can I give the importance to banner?
for example telling that particular banner comes up
30% more than other banners or ...

Is there any simple way to do this kind of things in
Zope?

Thanks.

I downloaded Zope-2.1.6-linux2-x86.tgz. I unpacked it in /usr/local/bin,
then ./install, then ./start. Please see below and advise.

I tried logging in several times. I even used python zpasswd.py access and

Subject: [Zope] error with ptk
Message-ID: <028801bf9584$2e178be0$722624d5@amazigh1>

I began to download and to install PTK's last version recently. I installed
the product by following procedure described in the file " Read Me ", and I
so obtained three new elements in the section products. But when I try to
create a new element "Portal", Zope sends back me an error. I search so the
details of the installed products and I notice that in the part " DemoPortal
" certain elements are broken:

It is a question of:
 . " DemoPortal / Portal "
 . " DemoPortal / PortalWizard "
 . " DemoPortal / Wizard "

In fact they are all the DemoPortal's ZClass which are lacking. Can it
involve a conflict with another product? Is it necessary to settle PTK on
Zope's clean version?

I work with:
Zope version: Zope 2.1.2 (binary release, python 1.5.2 , win32-x86) on Win
NT4 / sp4, as well as with Zope 2.1.4 on Linux Mandrake 7.0. (on whom I did
not test PTK because it is my working environment, and I do not wish to
pollute it).

Thank you for advices. I intervene only rarely. What is well , it is that
major subjects and basic questions were approached in depth, repeatedly,
what allows to avoid resting the same questions. By getting back this
information, the people of the ZDP make a formidable job. That has the taste
of object oriented thinking...

Your best bet is http://zdp.zope.org

I hope you can get more out of it than I did...

PS: In reality, the best way to learn Zope (IMHO) is to start with the guides
and then read the mailing list religiously.

The guides are at:

good luck, it is worth the effort ;-)

It doesn't work too. I can't understand why.
More general, I'd like to extract all the variables available in a
namespace (and if I can do it, I'll can get the list of the fields).

Hi,

I'd like to add, modify and delete entry in an LDAP directory. I've
quickly read ZLDAPConnection's source and I guess that fonctions
"_addEntry", "_deleteEntry" and "_modifyEntry" can do what I'm looking
for, but I can't imagine how ! :)
I've tried a LDAPlink.addEntry('dn','values') in a dtml-call. Apparently
it work, but there nothing new in the directory :(
Have you any ideas ?

Same suggestion. How it works (one possible way of doing it):

Using a standard Linux installation, create a document with your data in a
Python method and safe it as a local (temporary) file (e.g. using the PDF tools
that exist for Python, e.g. "PIDDLE"). Then just do the following in your Python
code:

import os
os.system('lpr /path/filename')

This works under Windows, too. Just replace the system call by something
appropriate like "copy path\filename lp1".

It should also be possible to redirect the stdout data stream directly to the
printing device. 

I have also found some more sophisticated solutions:

- using the classes wxPrinter and wxPrintout from the wxPython package
- for Windows: using the Printer API directly with
   import win32ui
   import win32com
   ... (gets complicated)

You can also have a look at ZDP : zdp.zope.org

Subject: [Zope] getUserObject Attrib Error
Message-ID: <Pine.SOL.4.10.10003241424100.6039-100000@marlowe.informatik.rwth-aachen.de>

Hi All!

Now and then there are strange things going on with my Zope 2.1.4/Linux
Intel installation.
Ok, here is what happens:

http://www.myhost.de:8080

raises a Zope Error (Attribute Error, getUserObject)

http://www.myhost.de:8080/manage

requests authentication and I give as UID/pwd as the superuser's pwd.
Again, strange Error-Messages.

I repeat (non-deterministic number of times) this and suddenly: everything
is ok.

What can this be??

Regards, Ingo.

Eddie,

I seems from your traceback that the user you are using to
_run_ your Zope process does not have permission to read 
some (or all) of the Zope files from the filesystem:

> IOError: [Errno 13] Permission denied: 
> '/usr/local/bin/Zope-2.1.6-linux2-x86/lib/python/App/manage.dtml'

You need to make sure that either you run Zope as the same 
user you used to install it, or change the filesystem permissions 
so that the user you are using has read access to all of the 
Zope files (and write access to the /var directory and any files
in the /var directory).

Hope this helps!

Authentication is not your problem, the user your Zope is running as
does not have permission to read it's own files.  Keep in mind that if
you run Zope as root, Zope will automatically demote itself to the user
'nobody', this is a standard practice of many servers as running a
server as root can be a security hazard.  If you want to run Zope this
way, then make sure that 'nobody' can at least read everything, and can
write to the /var directory.  

Otherwise, run Zope as a user that can read its files.

So do I.  Several people have reported this bug, but I cannot reproduce
it.  No one has been able to reproduce it or tell me how to reproduce
it, therefore, I cannot fix it.  The only thing I can tell you is that
it has to do with ZClasses that catalog themselves and that it happens
rarely and that updating your catalog allways fixes it.  I suspect it
has to do with poorly engineered ZClasses.

The method that contains this code.  You are probably experiencing some
sort of infinite loop.

Message-ID: <00032409234800.00783@modemcable215.47-200-24.mtl.mc.videotron.net>

HI,

How to get information about a ZClass property sheet from outdside the ZClass?

The goal is to create a "myzclass_addForm" that generate automatically the
input fields for the ZClass propertysheets.

In tried this:
/Control_Panel/Products/MyProduct
	myzclass
	myzclass_addForm
	myzclass_addPermission
	myzclass_factory

I just modified "myzclass_addForm" to add:

<dtml-in "ebook.propertysheets.common.mypropertysheet.propertyMap()">

...stuff to generate the input for each property.... 

</dtml-in>

It worked fine when I called "myclass_addForm" by clicking on the "View" tab of
the myzclass_addForm management screen. However if I try to add a MyZClass
instance from anywhere in my Zope hierarchy, I get the following message:
"Authorization failed. Retry?" and if I cancel:

"Unauthorized

       You are not authorized to access common."

I tried to change permissions and proxy of my myzclass_addFrom but it doesn't
work.

Can someone be sweet enough to tell me where I could find docs on how to access
the propertysheets elements.

Thanks

I submitted the ZOE announcement to /. and Devshed (www.devshed.com). I got
back something from /. asking for more information and DevShed posted it
under news.

Hopefully it will be up on /. today. Hope the Zope.org servers are ready.

:)

There is also a Zope Discussion Board at DevShed (based on UBB) which is
pretty quiet now. It might be a place to get people learning about Zope who
are not going to be a part of mailing lists.

Hi,

if you want to hide them based on permissions, this is easy. Set the "Access
content property" to the correct value and it works. This is the way I do it
for my application, where I have browseable admin area and a public area. If
    an admin logs in, he sees the admin area too.

If this is not the case, then do a 

<dtml-tree>
    <dtml-if "id=='x'">
        display as you like it
    </dtml-if>
</dtml-tree>

Bye, Oliver

I didn't create the images, but I would not surprised if they were
created then as there was a big push to get things uploaded before
the 1st.

I can have them reupload the images to work around the problem, but I
agree that it would be much better to know what the bug is.

I've implemented a variant of Michel's suggestion. Let me explain what I
am trying to do. I'm trying to implement the
SelfServeFAQ:www.lcg.org/ssfaq (SSF),written in php3, within my Zope
website. To give a consistent look to my site, I also want to wrap the
SSF with standard_html_header, etc. So when a visitor goes to
www.mysite.com/FAQ they are really being served
/SSF/directory/index.php3 wrapped with my Zope code.

The problems come when a user clicks on www.mysite.com/FAQ/add.php3 or
some such similar link in the HTML produced by index.php3. I tried using
mod_rewrite in Apache, but found that Zope used
www.mysite.com/FAQ/add.php3 as the base for all the links in the
wrapping code. The only way I found to avoid this was to use the "[R]"
flag in the Apache RewriteRule. 

But I want SSF to be transparent to the user so instead I used
SiteAccess to rewrite /FAQ/add.php3 to /FAQ and pass /FAQ/index_html the
script name "add.php3". index_html then uses lstaffor's How-To tip( use
"Client.call( www.mysite.com/SSF/directory/add.php3)[ 1 ]" ) to embed
the PHP script call in my Zope page. In addition, I wrote additional
code in my accessRule to pass images in the PHP directory tree via Zope.

There is one inconveniences with this approach: I had to hack SSF to
remove the <html> tags and some others returned by Client.call (it
worked otherwise but, hey, I want my HTML code to be clean). But all in
all, the resources of Zope (the code and the community around it)
allowed me to solve the problem with very little modification of the SSF
PHP directory tree contents.

If there is wider interest on this I could write a How-To on it.

Michel, I take back the assertion in my private email.

I've just determined that this glitch in my
CatalogAware Journal ZClass (using a custom catalog
as per http://www.zope.org/Members/AlexR/CatalogAware)
arises whenever a user edits an instance of this class.  

Users are using the standard Zope management interface 
but I have substituted the standard Properties View 
with an "Edit Journal" View.  This is a copy of the 
Journal_AddForm method (with default values culled from 
the now existing instance).

As per #4 in the above How-To, on submission this calls 
the following DTML method which puts my publicationCatalog 
in a strange state (requiring the update):

<html><body>

<dtml-call "propertysheets.Properties.manage_changeProperties(REQUEST)">
<dtml-call reindex_object>
<p>Changes saved.</p>

</body></html>

I desperately need to sort this out before users start
making changes.  I certainly can't do an update of
the catalog on every edit of an existing Journal
instance.

Any help is much appreciated.

Cheers,
Darran.

Hello,

I intend to get from fatbrain the e-matter edition of the Learning Python

The problem is that they mention that e-matter works only on windows

I can use it while working my computer, which does not run windows.

Thanks in advance.

What would constitute a poorly engineered ZClass?  I've seen this
problem with a ZClass that is descended from just CatalogAware,
has a few properties, and for which I've rewritten the Add and Edit
methods to call reindex_object.  I'm not sure how I could engineer
this simple class better, but I don't really understand why I have
to rewrite the Add and Edit methods to call reindex_object,
so it could well be that there are improvements that could be made.

In my case, I did not even do an update catalog.  After adding
a few additional objects, the error message went away on its
own.  (I didn't do a catalog update, because if I do that the
meta data for the id field gets completely screwed up, so I stay
well away from catalog update).

I am running under SiteAccess, and I have a sneaking suspicion my
problems orignate there.  I'll be moving the database to a
dedicated server soon and will remove SiteAccess.  If I see the
error again at that point I'll let you know.

Imagine I have a python extension, with zope id pyFetch

I want to call this in a manner similar to:

  <!--#/let-->

So it seems to evaluate and call the extension without adding the
parameters.  I guess I need something like lambda in python.

Can anyone help me please?

Subject: [Zope] Newbie question: using backing files.
Message-ID: <013c01bf95b2$9320f070$afe9612f@entrust.com>

I have a situation where there are some HTML files which I do not control
that I would like to open up to access through my Zope server.  I don't want
to import these HTML files as Zope objects because these files will
frequently be edited and updated in place and I want any changes made to
these HTML sources to be immediately reflected in Zope as they occur.  I
also don't want to just use a URL to access them because a) the end-users
shouldn't be aware that they're exiting Zope scope for these items and b) no
URL could possibly point to these files since they're actually stored in a
revision control system through a "view" (in essence, a virtual local
directory tree).

So what this basically boils down to is this: I'd like to take a URL like
this...

    http://my.intranet.site/Documentation/ComponentSpecs/MyComponent.html

...and have the logic behind it conform roughly to the following pseudocode:

    1. Switch to "/viewdir/source/component/MyComponent/doc".
    2. Open the file "ComponentSpec.html".
    3. Serve up the contents of that file to the user.

The user should see no visible signs that the data comes from outside of the
Zope environment.

I've already investigated using an external method to accomplish some of
this.  For example I served up an outside file in almost exactly the way I
wanted to accomplish this using code like the following:

    def testMethod():
        s = ""
        f = open("/viewdir/[...]/ComponentSpec.html", "r")
        for l in f.readlines():
            s = s + l[:-1]
        return s

Indeed this does EXACTLY what I want.  (In any production version of
this--this was only a quick'n'dirty hack--I'd be doing some significant
caching and version checking.  But the example gets the drift across.)  The
only problem is that I can't figure out how to translate a URL like the one
I provided above into a method call like testMethod("MyComponent").  (The
documentation on these things is a bit... spare.)

So does anybody out there have any suggestions?  I'm not afraid to get my
hands dirty with Python (it being my scripting language of choice for the
past 4+ years) and I'm not afraid to learn Stupid DTML Tricks.  I just don't
know enough Zope yet to even be dangerous.

Subject: Re: [Zope] Printing from Zope.....Report writer building


I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

I haven't bought the eMatter edition of Learning Python =), but I did by the
Eff-bot's guide.  I was able to print it fine, although personally I prefer
nicely bound books to large amounts of single-sided A4/letter pages with too
much whitespace around the borders.

Also, know that some folks have had problems with eMatter's distribution
schemes, especially those with non-US installations of Windows, from what I
gather.  Luckily, I hear that fatbrain's technical support helps folks get
past these issues.

On the positive side, I do like the ability to search PDF files.

the 'address' mentioned there is the port (one of the ports) zope is
listening on. this means either you already have some process (zope?)
listening there or your os thinks that there is some process on this
port. 

in the former case look if there's one of your zope processes still
there (e.g. 'ps auxw | grep python' to list your python processes (on
linux)) or if there's some other process using it ('socklist' will
tell you if its in use); in the latter wait a little, the os will
usually grok this eventually.

hth,

We have very erratic crashes, the only commonality we can find is
volume.  When requests are low the system is awesome, but once load
starts increasing we see frequent restarts, once an hour at least.  This
could be due to people experience slower response times and breaking the
connection to attempt a reload.  From what someother people have been
saying a 'broken pipe' error in zope_msg.log may cause all the threads
to die off.  The problem here is I generated 30-40 'broken pipe' errors
and could not crash Zope.

When you run ab against it are you hitting a wide variety of objects or
the same page over and over.  I've had Zope perform great accessing the
same page repeatedly but show some strain once you vary it's diet a bit
especially when cached SQL results are involved.

What server method are you using on the sandboxes.  We use a combination
of ZServer and FastCGI connections for our traffic, with all /manage
going through FastCGI and the actual public traffic using a mix of
FastCGI & ZServer.

I can't get this to work.  When I try it all the messages come on the
screen like they should, each service that is up etc, but the darn thing
will not answer requests.  As soon as I run the exact same command w/o
strace it works.  I've also tried to attach strace directly to the
already running processes, and no luck.

As soon as I'm able to collect more info I'll forward it to you.  Is
there anywhere else I should be posting this information?

Hi,

As I didn't receive any answer from my previous message, I guess it wasn't very
clear.

How can I get a list of property.ids, property.types of a ZClass propertysheet
from outside the product containing my ZClass.

I tried a lot of things but i hit a wall.

Thanks

This should be easy, if you can get Zope read access to the files...

Use Jonothan Farr's Local File System Product.

If I put a tree tag in the index_html document it gives me nothing.  If I put it
in a document in the same folder it show everything properly.  This seems odd to
me, can anyone clue me in?  I don't see anything in the docs about this
behavior, it says it should default to the current folder.

I don't know what you mean by "python extension" -- is this an ExternalMethod? 
A PythonMethod (it doesn't look like one)?  A method of a class defined in a
Python product (I don't see an instance anywhere)?  I'll assume an
ExternalMethod, because it looks most like your stuff.

Assuming you have a folder, which contains/acquires an ExternalMethod,
'pyFetch', defined as taking two parameters, as above (I'm assuming from your
description that you have the EM with a different ID than its underlying
function -- that works, but for clarity I would generally avoid that).  This
folder contains/acquires some method, 'list_hrefs', which returns a list of
objects which have an attribute, href.

In a DTML method contained/acquired by that folder::

  # I'm using a PythonMethod which returns a list of dicts,
  #  so I am using the 'mapping' argument to get its key/values to
  #  look like attributes.

  <ul>
  <dtml-in list_hrefs mapping> 
    <li><dtml-var "this().pyFetch( href )"></li>
  </dtml-in>
  </ul>

That works for me -- I get an unordered list of the results of calling pyFetch()
on each href "attribute".

Message-ID: <01b401bf95da$0c434e90$29a8efd0@atinucleus.com>

I use an external python function to return the SQL result set.

here it is: ( I reference it as an external method called getRes in Zope)
---------------------------------------
def doPySQL(self, zQry) :
    tvar1 = 'res=self.'+zQry
    exec tvar1
    return res._schema.items()
----------------------------------------

This function returns a set of key/value pairs that are the column_name/column number

Here is the dtml document I used for testing: (UserSettings returns info for a user)

-------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=getRes('Your_Query_Name_Here()'))">
<dtml-var "_.len(t1)"> Columns<br>
<dtml-var "_.str(t1)" html_quote><br><br>
<dtml-in t1>
<dtml-var "_.str(_['sequence-key'])"> = <dtml-var "_.str(_['sequence-item'])"><br>
</dtml-in>
<br><br>
</dtml-with>
</body></html>
______________________________

This code will give you a listing of column names and values
sorted by column name for every record returned by the SQL Query:

--------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=Your_Query_Name_Here(),t2=getRes('Your_Query_Name_Here()'))">
<hr>
<dtml-in t1>
  <dtml-in t2 sort=sequence-item>
    <dtml-var "_['sequence-key']"> = <dtml-var "_.getitem(_['sequence-key'])" html_quote><br>
  </dtml-in><hr>

Look at how Zope's management interface does it
($ZOPE_HOME/lib/python/OFS/properties.dtml).

You allready have a service that is running on a port Zope wants.

Zope wants 8080 (for web) 8021 (for FTP) and 8099 (for the monitor).

It's just a suspicion, and as I noted in my previous mail I cant tell
you constitutes a poorly engineered ZClass because I can't reproduce the
bug.  By 'poorly engineered' I mean both the possibility that the bug is
manifest of the user createing the ZClass, _or_ that the ZClass
implementation is broken.  I did not mean to point fingers.

Can you reproduce it deterministicly?

Because when you change an object, you must inform the catalog that the
object has change so it can update its indexes.

This is because one of your new objects filled in the missing hole, it
may have made the problem go away, but it didn't fix it.

This has never happened to me, can you reproduce this deterministicly

What I need to fix this is a way to reproduce it.  If you can do this,
then I need your help.  I would like to see your product, but first I
have to make sure that I *can* debug this using your product.  Your
produce needs to be self contained (not dependent on subclassing python
code I don't have) and must not use any relational database stuff as I
cannot reproduce your database environment.  In other words, if you can
drop your product into a clean Zope out of the box and reproduce this
problem, then you _are_ then man.

Message-ID: <38DBE09E.336A5056@hiretechs.com>

Felipe,

i had the ned for this too at the start of my current project.  I
actually have the fortune of having a smart printer.  If I shoot a pdf
via lpr, it just prints it.  It's an HP 4050.  

lpr -P HP4050_raw myfile.pdf works fine.  So I was just writing an
external method to slap that document to my printer.  But I stopped
thinking  about this because we decided online delivery of all documents
was okay and other things took priority.  

If you wanted to print more than just plain text, I guess the mime type
would have to have a "printer" application sort of, or filter just like
they have "viewers".

Has 'weighted' banners.
If you have 2 banners, each with the nromal weight of 1, each will
appear roughly 50% . If you assign a wieght of 2 to one of them, it will
appear roughly 67% of the time.

dtml-method I noticed the values  for loginid and password were the same each
time no matter what the user typed in the form. I changed the variable names
and everything was back to normal again.
Any ideas why these variable values were the same across multiple browser
sessions
Thanks

Yes.  It lives in the zope extensions directory though - blame lack of sleep.

Problem: In real life, I don't know that I'm calling pyFetch, it could be 
pyDontFetch or pyGoToSleep etc (the "#let call_method" is in another DTML 
method and there are a few alternatives).  All I know is that it shares 
the same signature.  Works fine if you call it directly.

Is there a better method than the equivalent of

  <!--#if "call_method=='pyFetch'"-->
    <!--#var pyFetch( href )-->
  <!--#elif "call_method=='pyDontFetch'"-->
    <!--#var pyDontFetch( href )-->
  ...


Thanks

Glenn

Stab in dark:

index_html is a 'DTML Document' and other documents are actually 'DTML

Zopistas,

how do I pull this off?

<dtml-in "objectValues(['Folder'])">
  <dtml-with sequence-item only>
   <dtml-unless noshow>
    do something
   </dtml-unless>
  </dtml-with>
</dtml-in>

I've tried messing around with the _ variable, with little luck.

This is part of a menu, and the thing is, even if I don't want to show
the folder in the menu, I don't want the menu to disappear when I'm in
the folder.

thanks,

Ethan Fremen

Hi everyone,

I'm hoping that someone on the list has some experience with NetWare's NDS.
The school district where I work is a NetWare shop with the exception of
the Web server which is running Linux. A couple of my students and I do the
Web stuff on the side.

Starting in the fall, I'd like to begin using the PTK and authenticating
users against our NDS directory. I'm wondering if anyone can tell me whether
Novell's recent release of their eDirectory product for Linux will affect
how we approach this. Are the existing LDAP Zope products sufficient?

Looking for some NDS Zen,
Tim

Some good news at last ...

When I set DEBUG in asyncore.py to 1 so I could view the lists going into
select, ZServer stabilised and hasn't crashed since. Smells like a race
condition and somehow the extra time it takes to print the list contents
stabilises things.

Still I cannot understand how the child process causes the supevising
(zdaemon) process to die too.

If your printer is setup is fine you can write the zope output to a file and
print it  using an external method 
If you can name your printale docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
pos = find(self.__name__, ".prt")
if pos >= 0:
redt = PrintJob(r)
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better
bet

This might be a seperate problem than The Mysterious Segment Violation. 
Can race conditions cause SEG faults? , I guess they can like any other
piece of code.  but I would expect a race condition to just spin the
process.  Can someone who I've spoken with about their SIGSEV problem
reproduce Pavlos' cure?

This makes me think it's a different problem also.  I get the feeling
you should be able to reproduce this problem on a fresh checkout on your
platform since it's so low level.  Can you check that?

The reason depends on how it didn't work.  Did it give you an error and

Interbase has gone open source, and the 6.0 beta version ( Windows,

www.interbase.com.

Looking at the contributed downloads, they have a Perl DBD driver, an
AOLServer database driver for Linux, and a port of the ArsDigita

Pity there is no Zope support except from ODBC in Win32 - and that is
extremely unstable in my experience.

Hello Darran,


I created a new CatalogAware ZClass in Zope 2.1.6 with a custom Catalog 
name based on the information in the Howto.

It works fine so far. I didn't have any similar error when I updated the 
ZClass properties a couple of times.

If you can trap this elusive ZODB error please let me know. I'll update the 
howto if it's related.


Cheers.

Message-ID: <002c01bf967a$b500ac80$3e5eb5cf@kevin>

Hi, I'm hoping to get some feedback to a question I've had about whether
making ZClasses Catalog Aware is a good idea or not. Below is a my question
I asked and a few ideas from a response I received, can anyone
validate/invalidate any of these statements?

kh

Question:
------------------
Is it good practice to simply make ZClasses Catalog Aware by default, or is
this something that should only be done when necessary?

Response
----------------

 - Object cutting and pasting does not work properly for CatalogAware
 ZClasses. Is this a problem for you? Note you can still copy, paste and
 then delete the original object.

 - CatalogAware ZClasses look slightly more "fragile". I've seen posting
 about (fairly elusive) errors in Catalogs with such ZClasses. Note I never
 experienced them firsthand.

 - You could first create a base ZClass, then subclass it when creating your

 it's a hack.

Get a user name at the Zope site. Publish your product there. Someone at DC 
will approve it, and it will be on the official list.

Pretty easy. :)

How do you do that? That is my problem. Sometimes I forget a base class 
other times I have too many. Can someone write a How-to?

Subject: [Zope] Some basic questions concerning ZClasses
Message-ID: <00032518334200.08192@promotor>

I've just started to work with ZClasses. They are really cool. But I am running
into some problems:

I added a folder to my ZClass. Let's say the folder contains images. Using the
images from the folder in my ZClass methods works fine. But like all other
ZClass "internals" (methods etc.) the folder (correctly speaking: its
instance; or is there no seperate instance of the folder???) is invisible to the
management interface.

Is it possible to make a folder visible in the management interface so that
a user can enter additional images? Same with dtml methods/documents ...


Is it true that the methods of a ZClass don't open a new property namespace for
each instance? If I change the property of a method in one instance it seems to
be globally changed.

How can this be solved?


Thanks in advance

Joachim.

Message-ID: <Pine.SUN.3.96.1000325132704.16062A-100000@grendel.csc.smith.edu>

Hi all--- 

I'm trying to modify my copy of the SimpleURL product, and I need some
help. SimpleURL defines a property Sections within URLDirectory, where
each line is a section within a URL list. I've added another property to
my URLDirectory--- SectionDescriptions. I want to generate a list like
this:

SectionName1 (link)
  SectionDescription1
SectionName2 (link)
  SectionDescription2

I have the following code in the index_html of a URLDirectory instance:

<dtml-in Sections>
	<dtml-let  section=sequence-item>
          <A HREF="section_list?ts=<dtml-var 
"_['sequence-index']">"><dtml-var
section></A> <br>
	</dtml-let>
</dtml-in>


Now I know there has to be a way to modify that so that I can display the 
sequence-indexth element of the SectionDescriptions sequence. What am I
missing here?


And a design question: my URLDirectory is already fairly large; I may want
to create folders within it for each section. How would I adjust the
method above so that it looks to subfolder properties to display the same
information?

While I still have the training wheels on, I've been trying to be careful 
to understand the difference between DTML Methods and DTML Documents. I 
thought I was doing OK until I noticed this about the management interface 
(when looking at a folder):

There is a tab for Properties but none for Methods
The tab for Contents contains Methods as well as Objects

So either I don't really understand DTML Methods vs Documents, or the 
management interface should, to be consistent, also have a Methods tab 
instead of lumping methods under Contents. I'm not complaining, just trying 
to figure out the tricks so I can take the training wheels off.

Hi,

after I settled my problems with the Zope authentification system and

people of course, I have another problem.

How can I allow a certain role to add local roles to an object? Which
permission do I have to activate, that this is possible? At the moment I have
solved the problem with a Manager proxy role, but I like to live without proxy
roles.

I have kind of a stupid question about sockets.  When starting zope (using

Note that what you're describing isn't really part of ZEO, it's really
more in the realm of what is already in Zope.  Thus, if you're eager to
add such a feature, you already have what you need.  Start tinkering
with the transaction machinery and see how you can extend it.

You asked one of the most tricky questions for beginners. If you look in 
the mailing list archives you will find the answer, but here my attempt:

I think of DTML Methods as functions that work on the folder they are in. 
Think about it this way: A folder is a class, then all DTML Methods are 
methods of the class Folder. They contain no properties other than id and 
title.
DTML Documents are on the other hand classes as well. So a DTML Document in 
Folder is like a subclass of the class Folder. Since DTML Document is a 
class, it can contain properties, while DTML Method does not.

Also, if you say: <dtml-var title> the DTML Method will return the title of 
the folder, whereby DTML Document will return its own title. That makes 
perfectly sense knowing the above definition.

How do I use them? Whenever DTML is called directly from the browser (like 
a link, or typed in  URL) I use DTML Documents. Whenever a document or 
other object calls DTML from inside I use DTML Methods.

I hope I did not confuse you. Don't take it as a major drawback to not 
completely understand the differences. It took me well over a month.

Regards,
Stephan

you can write the zope output to a file and
print it  using an external method 
not the cleanest way but works :
If you can name your printable docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
----snip snip --------
pos = find(self.__name__, ".prt")
if pos >= 0:
 PrintJob(r)
--snip snip----------
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better.
Another idea that I have tried :
inherit from DTMLDocument and create a new object type that will send itself to
the printer at the end of processing
 embed latex with dtml  and send the results to the printer using pdflatex.
There are some cool tex macros called context written by hans hagen that 
  can be used to create rich documents

How did you save the version? Did you click on the first button you see when
you bring up the Versin object in the management interface, or did you
actively go to the Save/Discard tab, where you can enter a message and then
save or discard the change?

To make a Folder show up in the ZClass instance, you should create it from
the ZClass_add method. For example, if your ZClass is called Foo, in the
method Foo_add, you could put a line:

<dtml-call "manage_addFolder('MyFolder')">

Then, every instance will have a folder called MyFolder in it.

Same thing applies for DTML methods/documents. Check out KM|Net News if you
want to see one way to provide default documents that the user can change.
KMNN also provides a way for the user to revert to the default.

Your properties should be stored on ZClass propertysheets. Then the
properties can vary from instance to instance.

Now that a beta version of Pike has been released (see
http://www.scripting.com/ and http://pikebeta.userland.com/), has anyone
given any thought to a Pike compatible interface to Zope?  It's a cool
way to interact with a content-management system.

Unfortunately it is only available for the Mac and Windows.

I hope you have got your answer ,  any way my 2 cents
ssi pales in comparision to
dtml. dtml makes template programming a breeze.  You will have to learn the
syntax and ssi statements have their equivalents in dtml and more. But zope is
best for dynamic stuff.   For static pages  I would stick with the http server.
For your problem I see coding some dtml to replace the ssi and refer to the
external cgi just as usual for creating the image dynamically.

I was just looking at that earlier today. I was thinking that it might be
fun to make some Pike-compatible stuff. Also, it might be interesting if we
can set up a preferences system on top of LoginManager that is compatible
with the UserLand spec.

Mmmm... interoperability.

I looked briefly at the XML-RPC spec this morning. It certainly seems
plausible to create Pike compatible interfaces for specific products. Zope
and Frontier work pretty differently, but from a content-writer's
perspective there does not need to be a difference.

The people who maintain the _other_ Pike (http://pike.idonex.com/) will
be happy about this -- not.

Why can't people do a little name research before they hijack somebody
else's name for their project? This new Pike will only hurt the original
Pike's reputation, possibly even forcing the latter into changing its
name.

Pike is the C-like, interpreted OSS scripting language that powers
Roxen, a web/app server that competes directly with Zope, as well as
this Manila/Frontier thing.

I'm sorry, the corrected text above is what works. What never works is
<dtml-with sequence-item only>.  The error I get with <dtml-with
sequence-item only> or <dtml-with _[sequence-item] only> are:

Do you see what I was trying to do?  I wanted to see if just the
sequence-item had the boolean attribute "noshow"

Ethan,

Try something like (tested, but not in this situation, i.e. I use it a lot
and it works YMMV):

<dtml-with "PARENTS[-1].net" only>
  <dtml-in "objectValues(['Folder'])">
    <dtml-in aq_explicit only>
      <dtml-unless noshow>
        do something
      </dtml-unless>
    </dtml-in>
  </dtml-in>
</dtml-with>

| Note that what you're describing isn't really part of ZEO, it's really
| more in the realm of what is already in Zope.  Thus, if you're eager to
| add such a feature, you already have what you need.  Start tinkering
| with the transaction machinery and see how you can extend it.

Except at the ZEO level, the conflicts must have been resolved.
I only want to replicate the state of play at the ZSS end.

Otherwise I could alter ZEO to take a list of ZSSs and do a 'broadcast' and
have them all do the same work (hoping like crazy that all transactions
arrived at all servers in the same order). Then I would have n copies of the 
primary ZSS. Failover from this point is almost trivial. 

The other option is to get the ZSS to forward transactions in the order
IT gets them and send them to a list of servers it knows about. This is
slightly cleaner, since all of the Zope machines don't need to know
about all of the ZSSs.

The other major problem is, that if I do this work, I will be unable to 
contribute it back to the project for some time (if ever). I don't really
have the facilities at home to be able to do ZEO type work, my current
employers (where I have more available resources) like OSS, but, tend to 
treat it as a code repository, rather than a symbiotic relationship.

netstat -a should tell you what ports are being listened to.  try 
./start -m '9898'
and if it works, well, then you've probably got something listening to
the monitor port.

Note that while http can be virtualized (listen on selective IP's),
monitor and ftp cannot, so you have to pick your ports accordingly.

Try this (untested), assuming the name of the method you want to call is stored
somehow in the variable 'methodName'::

  <dtml-let methodToCall="_[ methodName ]">
    <dtml-in list_hrefs mapping>
      <dtml-var "methodToCall( this(), href )">
    </dtml-in>
  </dtml-let>

Brad Clements has done a bunch of work on melding Python with NetWare -- he was
to present a paper on it at the last Python conference, but couldn't get there
due to weather.  His paper was part of the procedings, anyway, and may be online
somewhere under www.python.org.  His e-mail address is bkc@murkworks.com.

I think I even remember reading that he had Zope up and running as an NLM.

The Gestalt System project aims to develop a free, Open Source,
object-oriented software framework which makes use of other free, Open
Source software tools for the purposes of managing, analysing, and
reporting on quantitative data in a manner which is suited to modern,
networked computing environments in which processor, memory, and storage
resources are abundant but time is scarce and requirements are forever
changing. 

The Gestalt System may be of particular interest to Zope users because
we propose to use Zope to provide some important aspects of the
project's
infrastructure.

Full details of the project proposal can be found in the Gestalt System
Manifesto which is available at http://gestalt-system.sourceforge.net 

We welcome any comments or suggestions you may have on the project
proposal - please send them to

I was very confused about this  - the only Pike *I* knew of, is the core language of the Roxen webserver (www.roxen.com), which has been going for some time. As the Roxen team are about to shift version 2 of their server it seems like some lawyers are going to get some bunce here :(

Subject: [Zope] Accessing ZSQL connection from external method
Message-ID: <v04220801b503b1dd8153@[134.76.23.194]>

Howdy!

I'm making heavy use of MySQLdb in my external methods. Now I just 
realized that ZSQL-connections are kept open permanently and it would 
save a lot of time if I wouldn't have to open a connection each time 
my external method is invoked but use the already existing 
ZSQL-connection instead.
My question: How can I access a ZSQL-connection (ZMySQLDA) from an 
external method?

--Ragnar

P.S.: I benchmarked MySQLdb and found that opening a connection took 
1.2ms on my systen whereas a very short request for authentication 
took only 1.1ms. So beeing able to use an existing connection would 
result in about 100% performance gain (at least at first glance).

Subject: [Zope] anonymous Products?
Message-ID: <38DE0A95.CF7CA9A7@imeme.net>

Zopistas,

I need to have a dtml-method that does manage_clone,
manage_changeProperties, and manage_users.

It has to let an anonymous user do this:  I have to set up accounts for
people automagically.

I cannot seem- either with a product or just a straight method- to give
it the permission it needs to be called anonymously.

If anyone could give me a hint as to how to achieve this, that would be
great.

I looked at http://yyy.zope.org/Register/register.html , but I cannot
seem to get the dtml code for the actual new-user-maker.

Answer: make sure REQUEST has confirm and roles:list properties (the
latter isn't absolutely necessary, but you'd just have to set it later
anyway.)

Subject: [Zope] Performance Testing / Expections
Message-ID: <20000326232738.A30471@bob.sesgroup.net>

Ok,

I know it has been asked a couple of times before on the list, but
there hasn't really been any absolute conclusions on the type of
performance to expect from zope and/or how to tweak it for the best
kind of performance.

Over the last two days I have been doing some testing and would like 
to hear on opinions if these results are similar to other peoples.

Firstly the machine specs are:

PIII 450Mhz
128Mb 
IDE Harddrive

Running Debian Potato

Zope is running through Apache with PCGI.

All tests were run using ab.

First I tested apache to see how fast it was as a benchmark.

1000 requests, 25 Concurrent.

/usr/sbin/ab -c 25 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

Results:

384 requests per seconds (rps). Avg wait: 54ms. Max Wait. 83ms. Throughput: 20MB/s

1000 requests, 1 at a time.

 /usr/sbin/ab -c 1 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

425 rps AvgWait: 2ms MaxWait: 3ms Throughput: 21MB/s

The I tested the same document servered statically through zope. (From zope's root)

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/testemc"

42 rps Avg Wait: 514ms MaxWait: 743ms Throughput: 2MB/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/testemc"

45 rps AvgWait: 21ms MaxWait: 29ms Throughput 2.3MB/s

Next on line was a moderately dynamic page. Dtml only, no DB or Ext. Methods.

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/sesgroup?cu
rrentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/siteinfo/index_html?"

4.97 rps AvWait: 4.4s MaxWait: 5.6s Throughput 21kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/
ecom2/sesgroup?currentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/
siteinfo/index_html?"

5.09 rps AvWait: 195ms MaxWait: 198ms Throughput 22kb/s

Then finally testing a page with the same amount of DTML complexity but
some external methods which call a database using pygresql

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps  Avwait 16s  MaxWait 20s Throughput 19.51 kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps Avwait 768s MacWait 789 Throughput 19.55 kb/s

In summary serving straight of apache is very fast, and doesn't suffer if 
multiple people access the site at once.

Static Zope (which you wouldn't really do anyway) was acceptable speed and
didn't really suffer too badly if there were multiple accesses.

Dynamic Zope was fair in speed, but proably still fast enough, at least for
my site anyway. It started to suffer in a bad way with multiple accesses, 
up to 5 sec response time.

Highly dynamic Zope was very bad in rps and hopeless more multiple access.

Now I have only been in this game I a while so I don't know how critical 
the multiple access thing is going to be. I am expecting at most 1000 
visitors each day (say a 10 hour period). So 100 visitor each hour shouldn't
cuase me any problems at the moment.

I guess how I would like to know if anyone out there knows how to improve 
this performance at all. Can I throw memory and processors at it and make
it go away? Obviously there are some things in the highly dynamic bit
which I will need to speed up, however how can I make just normal
dtml execute faster? The prospect of ZEO has certainly helped in this
area but surely I must be able to sqeeze some more performance out of this
machine.

Thanks in advance.

1. Generate Expires headers for your pages, and maybe handle
If-Modified-Since headers too (see OFS.Image.File for an example of the
latter.)  This lets the browser cache results of yor pages, which won't up
your requests-per-second but will reduce the number of requests you have to
handle.

2. Cache results of dynamic pages and then serve that up instead.  This can
speed things up by a factor of 5 for pages that are only a little dynamic.


I'll follow this up in a short while with an example of generating Expires
headers in DTML.

The following dtml code will tell the browser that the page expires one hour
in the future:

<dtml-call "RESPONSE.setHeader('Expires', _.DateTime(_.DateTime().timeTime()
+ 3600).toZone('GMT').rfc822())">

Wild idea: Do you ever get errors when you try to compile a big, big
program, specifically the Linux kernel?  It seems as if a large number
of seemingly perfectly functioning PCs have memory errors that only
show up under specific, not well known access patterns.  Compiling a
big program is a process that can exhibit these error prone
patterns[1][2].  Perhaps Zope under load causes the same access
patterns?

[1] This is not an urban legend.  I have seen it.
[2] Search for gcc and signal-11 or sigsegv.  There are a couple of
    web pages out there about this.

I get them constantly when recompiling Mozilla, which is a daily task almost.
And bad_slab_magic, and random segv's.

I'll be running a good memory stress test soon, to see if I can pinpoint the
offending Mem. bank.

You can embed SSI within Zope. I'm currently writing a How-To on it.
Depending on how complex your inclusion is, you may be able to get away
with using Apache rewrite rules. If you want to embed the SSIs within
your Zope pages, you can resort to using SiteAccess and a call to
Client.call. Take a look at the thread "How to serve PHP within Zope"
for a more detailed explanation of what I mean. I should have the How-To
finished soon. If you are in a rush, I can send you a draft.

Well, that is food for thought today. If anyone has some really good
analysis of this (since this is my first time using AB) that would be
great.

netstat -a shows only ssh, http, smtp, sunrpc, and syslog sockets open.  
Nothing too wierd.  Like I said, using other socket numbers (e.g. 9898)
doesn't seem to fix it.

I can offer you an NDS user folder if you're running Zope on Windows or 
NetWare itself. For Linux, I suggest using LDAP

Message-ID: <Pine.LNX.4.10.10003261217150.15096-100000@odeon.net>

	Greetings,

	I've got a form that has three fields.  One for year, one for day,
	and one for month.  The selection parts of the form are similar to
	the following:

   <select name="date_mm">
    <option value="01">January          
    <option value="02">February     
    <option value="03">March
    <option value="04">April     
    <option value="05">May     
    <option value="06">June     
    <option value="07">July     
    <option value="08">August     
    <option value="09">September     
    <option value="10">October   
    <option value="11">November     
    <option value="12">December    
   </select>


	What I'm trying to do is pull the 'date_mm' (along with the other
	two fields, 'date_yy' and 'date_dd') into the namespace area so I
	can do something like:

  <input type="hidden" name="event.date" value= \
    "<dtml-var var_yy>-<dtml-var var-mm>-<dtml-var var-dd>">

	I would expect that I can use something like:

  <dtml-call "REQUEST.set('var_mm', 'date_mm')">

	However, that doesn't work like I'd hoped.

	Any help would be greatly appreciated,

	Jeff

Subject: [Zope] dtml-tree question
Message-ID: <20000326221801.A17865@owl.rhein-zeitung.de>

Hi, 

I have a problem with dtml-tree. But I think that is just a problem I have,
cause I don't completely understand the dtml-tree thing.

I have the following dtml code snippet

<dtml-tree skip_unauthorized=1 branches_expr="objectValues('Folder')" sort="order">
    <dtml-if "'index_html' in objectIds()">
        <a href="<dtml-var tree-item-url>" target="contentframe"><dtml-var title_or_id></a>
    <dtml-else>
        <dtml-var title_or_id>
    </dtml-if>
</dtml-tree>

Well, I traverse my folder structure to build a nice dtml-tree from it. So far
the insertion of links, the if-clause of the dtml-if statement, works really,
really fine. But I also want people to be able to click on the elements that
are part of the tree, so that they don't need to click on the plus signs but
can also click on the text next to the plus sign. This is the else-clause in
the dtml-if statement. But everything I tried didn't work. 

Is is solveable? And how? Or do I have to build my own tree using a recursive
call of a dtml-in loop?

Bye, Oliver Andrich

P.S.: For all of you who have seen my questions about users, roles, and so on.
I like to tell you, that I am writing a HOWTO on this, so that people don't
have to dig into the information and bother people with questions, as I did.

Looks to me like you're close...

<dtml-call "REQUEST.set('var_mm', date_mm)">

Note that there are no quotes around date_mm. Assuming that this DTML is in
something POSTed to by your form, date_mm will be available in the
namespace, and you can use it like a normal variable.

Your question is not quiet clear, but I will make some assumptions and then 
try to answer it:

I assume you want to do that all in the same file, without sending a form. 
In this case what you want to do is not possible, because you ask the 
server to know something which does not exist yet.

A form is created in the moment the user submits it. So here is how you do it:

FILE: someForm

...
<form action="someAction">
   <select name="date_dd">
      <option value="01">01
      <option value="02">02
      ...
   </select>
   <select name="date_mm">
      <option value="01">January
      <option value="02">February
      ...
   </select>
   <select name="date_yy">
      <option value="1999">1999
      <option value="2000">2000
      ...
   </select>
   <input type="submit">
</form>
...

FILE: someAction

...
<dtml-call "REQUEST.set('eventDate' , date_mm+'/'+date_dd+'/'+date_yy)">
...

So you combine your date AFTER the form is transmitted. I cannot think 
about a case, where you need it differently. If you have one, you should 
revise your design, since weird syntax is mostly due to bad design.

Regards,
Stephan

Ben,

Hi...

This topic is probably better suited for the main Zope mailing list so I
moved my reply to it there.

Err... we'd all love to see better docs written for this process.  Maybe
you can write them once you get it done.  :-)  No, Zope does not
necessarily need to be installed from source, but I think the MySQLdb
stuff needs python include libraries.

Can you give more specific questions about your problem?

Some hints anyway:

 - the MySQL development libaries need to be installed on the machine.
 - python 1.5.2 libraries should be installed on the machine

Yeah I am currently thinking of the best way todo this. I guess I now reach
another point. Does anyone know how to make External Methods persitent, or
would I have to store cached information on the filesystem. Does ZCache work
for External Methods, are there any plans todo this? I don't mind writing
code for ZCache todo this if the current framework easily allows this.

Thanks,

 I usually  create python classes instead of plain external methods and
instantiate them  as zclasses. This way I can cache information with inthe
python class as class members. If there are hooks in the zope framework to do
somthing similar (ie make use of zcache etc) please post

Not convinced that's it tho.

Side-note:  I've patched ZServer/medusa/asynchat.py line 255 - the 'first'
method - to check if self.list actually has anything on it before
returning:

        def first (self):
                if self.list:
                        return self.list[0]
                else:
                        return None

Since I did that, I haven't been able to reproduce the crash.  I doubt
that's the problem as such - I'm still leaning toward a race condition
somewhere - but the fact that it hasn't crashed since then is curious...

Oh, and strace'ing and adding debug and so forth seems to cause the problem
to display subtly different behaviour - which makes me unhappy...

Hi there,
I've got an 8-character string, say str='12345678'. With
<dtml-var str> ofcourse I get 12345678.
How can I display only part of it ? Say the first 4 chars
(1234) or the next 2 (56) or the last two (78).
In python I know this can be done with something like
str[:4], str[4:6] and str[6:].
Any help ? (Hope I didn't sound too newbish !).

Subject: [Zope] Passing data to/from Python
Message-ID: <NCBBJGNEKLKGLMECHMLGIEFOENAA.wexler@ccr.jussieu.fr>

Dear Zopistas,

I am in the process of learning about Zope, and trying to
determine whether to make the switch from pure Python CGI
scripts. If someone could answer the following questions (and I
apologize, as it will probably seem naive), it would really help.

Let's suppose I have a page where the user queries a data base,
for instance a telephone directory. The telephone directory is in
an Excel file. At present, I have a CGI script that opens an
ODBC.Windows connection, executes an SQL query, and outputs the
results (names, phone numbers) as an HTML table using "print".

What is the best way to do this in Zope? Here are the points that
I don't get:

1. It seems that the only way to establish a DB connection is
through Gadfly. There are warnings everywhere that Gadfly is
inefficient. Therefore, I want to use ODBC (ODBC.Windows), like I
did before. How?

2. I might eventually need to do complex calculations on the
retrieved data, so I would prefer using Python code in an
external method, rather than a DTML method. In order to get Zope
to accept the line "import ODBC.Windows", I had to copy the ODBC
and DateTime directories from my regular Python installation
(PYTHON/lib) to ZOPE/bin/lib. But then, when I try running the
script, I get one of the following problems:

   a. If I go through authentification, the script runs, but I
   cannot establish the connection to the database.

   b. If I type in the URL of my search page directly, without
   authentification, I get a Zope error: "initialization of
   module mxODBC failed
   (exceptions.AttributeError:mxDateTimeAPI)".

Is my ODBC.Windows installation wrong, or do I have a more
fundamental problem?

3. What if my Python function in my external method wants to
return information to my DTML method? For instance, how do I
return a Python list, and what do I do in my DTML method to
process it (e.g., output a line for every member of the list)?

4. The way I call my Python function now is through the <form
method="POST" action="search"> tag, where "search" is the
external method ID. The form has a field called "name", and my
Python function has an argument also called "name", and so it
recuperates the string that was entered in the "name" field. Can
I pass the "name" as an argument to a DTML method?

If these questions have answers, I would really appreciate them.
Otherwise, if I'm completely off-base (for instance, if I'm
thinking in Python terms and not in Zope terms), please point me
in the right direction!

Thanks in advance.

Nonono.... ZOPE uses the Gadfly db to store "zope objects".  It can also
connect to other DBs, and access them via SQL methods.  There are a number of
DB interfaces, including an ODBC interface.

afaik, you can simply return a list.  As for iterating through the list, you
would use <dtml-in myMethod> stuff goes here </dtml-in>

All fields passed in a POST are available via the REQUEST.form map.  Also, so
long as they don't match the name of other objects in the namespace, you can
access then directly.  So, your 'name' field will be accessible:

<dtml-var name>  <-- assuming you don't have any other objects called "name"
<dtml-var "REQUEST['name']">    or
<dtml-var "REQUEST.form['name']">

Gadfly is just one of  the db's you can use. The aquaduct product family gives
you many options
 look at http://www.zope.org/Products/DA/ZODBCDA for the ODBC
adapter.  This is defenitely the easier way

You can do quite a bit with dtml unless of course you prefer python  and
sometimes it is easier to do stuff in python,  dtml is not a replacement by
any means

return a list and process it using  <dtml-in > which behaves  very similar to a
database cursor 
>  Can

Absolutely with the dtml  programming you can do the same things and more 
All the form variables show up in the REQUEST object and become part of the
namespace in your script,you can use them like any other variable in the
script

There's an ODBC database adapter for Windows machines.  It does not work
under UNIX.  The Sybase DA works against MS SQL Server 6.5 and below
from UNIX.

Look under "Downloads" on Zope.org.

Also read the ZSQL User Guide.

Hmm.  I've never seen ODBC.Windows.  We've punted on supporting ODBC
under UNIX, and we're now supposed to be contracting out to some other
folks to provide it for us.  Not sure when this will happen.  You can
try to write your own ODBC DA for UNIX/Linux.  There is a HowTo on
writing a DA someplace out there that Chris Petrilli wrote.

external method named "pyfunction":

def pyfunction(self):
   return ['1','2','3']

a dtml method that uses pyfunction:

<dtml-in pyfunction>
   <dtml-var sequence-item><br>
</dtml-in>

Should output:
1
2
3

If you use an external method to handle the form input, you should be
able
to get at its attributes by looking in REQUEST ala:

def myformhandler(self, REQUEST):
    a = REQUEST['a']
    b = REQUEST['b']

where 'a' and 'b' are form field names.  This can also be done by:

def myformhandler(self):
    a = self.REQUEST['a']
    b = self.REQUEST['b']

Hey Mark,

This is your lucky day... Zope does this without even blinking... I 
would say (and without starting a flame war) that Zope's ability to 
easily connect to databases is one its best features. To the 
questions...

1) Gadfly is the example. You connect to anything that there is a 
ZSQL connection product for (Oracle, Sybase?, PostGreSQL, MySQL, 
Gadfly)

2) You get back the data and can do anything you want with it. You 
can parse it, calculate it (although you might want to look into 
doing some of it in SQL) or just spit it out. Authentication has 
nothing to do with what you do with the data.

3) It is easy in DTML, just do a <dtml-in> to go over the list.

4) Yup. You build a form and send that form to a DTML method that 
processes the form. If you are super slick you have it in the same 
DTML method.

Don't worry about thinking in Python terms. I came from Python.. 
thought Zope was going to be easy, found out it hard than studied up 
a bit and now respect it. There are a LOT of things you can do in 
Zope, most of them "like" things you do in Python, just stated a bit 
different. The DTML reference guide is your buddy. You read that and 
come back here when you are truly stuck.

Now go Zope...

:)

Ok.. my mistake.. sorry.... thanks for correcting me.  I was under the
impression ZOPE stored data in a db, using gadfly as the default, and it was
refered to as ZODB for convenience.

Thanks for clearning that up for me.

Subject: [Zope] Problems with adding ZClass instances
Message-ID: <14558.57262.760790.737744@antares.int.plain.co.nz>

I'm have problems with a ZClass I'm working on that uses Folder as
it's base class and is supposed to install a set of default methods
when it's created. The trouble is that it won't when the webDirectory
is created, but it will when I invoke the same method from a tab afterwards.

Here's the body of webDirectory_add:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-if createDefaultMethods>
   <dtml-in "default_methods.objectIds()">
   <dtml-try>
      <dtml-call "manage_delObjects(ids=[_['sequence-item']])">
      <dtml-except>
      </dtml-try>
     <dtml-call "manage_clone(
            _.getattr(default_methods, _['sequence-item']), 
            _['sequence-item'], REQUEST)">
  </dtml-in>
  </dtml-if>
</dtml-with>

I'm assuming that the code within the <dtml-with ...> is effectively
opperating in the context of the newly created object, but when the
first manage_clone() is executed, it bombs out in _getCopy,
tripping over on this line:

ob=container._p_jar.importFile(f)

...because whatever container is, it's not a folderish object. 

So what do I need to do to switch to the new webDirectory object at

 Actually the limit is 4 GIG. however ext2 FS on Linux has a 2 gig limitation 
you can use a patch that will take it to 4 GIG, its available on the ext2 home

First of all, someone needs to let you know that data should never be 
stored in an Excel file. Anyway, what you would do is use the Zope ODBC 
database adapter. The Gadfly one is the only one installed by default, 
but others are availible at zope.org

You really should be storing that in a relational database though. 
Speaking for years of database experience, Excel is never a good place 
to keep things.

This isn't really a Zope issue. It's a bug in your script or the serveor

Ask those in the ODBC.Windows mailing list; this is not a Zope issue.

You might consider though, not using so many external methods and 
whether writing packages - they are more powerful and can be more 
powerful. External Methods are usually for quick one-timers.

I beleive you can do just that - return it as a list, and use it like 
this inside DTML

<dtml-in externalmethodid>

Hang in there. Learning to do this kind of thing in ZOPE is hard - I 
know because I'm trying to do it myself.

<dtml-var "search(name=name)"> should do the job, if I understand your 
question right. (Works like in Python.)

And remember: If you want performance, use any OS other than Windoze. Two 
good free DBs are PostGres (currently in 7.0 beta 3, yeah!) and MySQL. If 
you go to the RedHat site and sign up, they will send you Oracle 8i for 
free (or do they not do that anymore). I think Sybase has a similar 
promotion program. For all these DBs you have Zope DB Adapters.

Zope is cool, the docs are a big issue (I know), but a lot of people work 
very hard to change that. If you have suggestions of how to improve them, 
mail: Zope Documentation Project <zdp@zope.org>. Thanks.

Stephan

sorting is ascendingly by default (taken that you put a sort in the
dtml-tag, like 
<dtml-in sort=id>)

turning the sort to descending is done by putting in 'reverse', like so
<dtml-in sort=id reverse>

It is always ascending unless you specify "reverse" as an attribute with no 
argument in DTML-IN

<dtml-in "objectValues()" reverse sort="id">
   ...
</dtml-in>

Message-ID: <000601bf97c5$3590d960$0200a8c0@digitalview.com.hk>

Hi

I've got a load of files (PDFs, TIFs) that needs to be accessible from
within a Zope application. I need to be able to link to them so people can
download them. What is the best way to go about it?

If I add them into Zope (ie [Add new item]>[File]>[Browse]... etc is there
an easier way of doing it? I've got hundreds of files to add and I don't
want to do it using the HTML interface.

If I have the files in directory outside of Zope how do I reference them?
Bearing in mind I only need to link to them for download, no need for the
information in the files to be accessible by Zope.

thanks

By searching of the documents using ZCatalog, in query I list words with
"OR", for example, "web or pop or mail" - all works well. But if in a query
with "OR" there is a word that is not in the index, ZCatalog finds nothing,
for example, "web or pop or mailvvv", but the documents with "web" and
"pop" exist. On www.zope.org the same effect. Is it possible to correct
this situation?

Subject: [Zope] zope search problems w/squishdot with latin1, locale fi_FI
Message-ID: <200003270923.MAA02125@katto.kaapeli.fi>

I'm using Zope 2.1.4 on Linux with environment LC_ALL set to fi_FI and
Zope started with -L fi_FI, and ZCatalog indexing & searching seems to
work fine.  (well, there's a problem with some documents having &auml;
etc. spelled out, but if ä is used everything works OK.)

BUT, ZDConfera & Squishdot don't work right.  For some reason, at some
phase of the indexing characters like ö (&ouml;, octal 366) in words
are converted to their octal codes.  This can be seen by looking at
the raw Data.fs file.  The result is that when I have a word like

kökköviesti

in the ZDConfera or Squishdot article, it can be found by search as

366viesti

It is converted in the db storing/indexing phase to something like
k\366kk\366viesti, which is then broken into words k, 366kk, 366viesti
which are stored into the textindex.

Any ideas on how to fix this?  I've looked at Splitter.c,
TextIndex.py, ZDiscussions.py and Squishdot.py, but I can't find
anything which would convert characters to their octal codes.

Aha! I have it!

Your external methods are given a pointer to self as the first
arguement.  You can use this to access any methods in the current
folder (self is the current folder)  So just call:

self.MyZSQLMethod(arg1, arg2)

where arg1 and arg2 are would be the arguments for the ZSQL Method.

Yes I am using postgres, however I am _not_ using the postgres adapter. 
I am using External Methods and python to do all data access since the data
requires formatting after it comes out of the database which is much
more easily done in python cf. dtml.

   Then you loose all the data caching done by the ZSQL methods.

Alas! It doesn't work.  It appears to fall down on the line:
  <dtml-let methodToCall="_[ methodName ]">

Traceback:
  File C:\PROGRA~1\Zope\lib\python\DocumentTemplate\DT_Let.py,

TypeError: (see above)

It seems evaluating this doesn't just give the string contents of the
dictionary item, it evaluates the actual external method call.

I think I'll have to give up at this point and take the cludgy option
(unless anyone can think up another way).

Thanks for your help.

Yeah I know, which is a shame, however the postgres db adapter is only a
development version and as I said we need to manipulate the data in python
before it comes out of the db. I plan on putting in my own caching routines
here, however this will still only get me up to at most 8 request per second,
which is proably reasonable for my application.

Cheers,

Hello,
i'm testing Zope 2.1.6 with Windows NT 2000. Everything is running fine
but... it's
slow updating the internal database. Each time you press the "Change"
button the wait is 30 seconds! On the same machine with Windows98SE and
Linux there is no wait.
All the other operations are working without any problems of speed.

Is there anyone else who tried Zope with Nt2000?

Thanks,
    Bruno

Message-ID: <38DFE1F7.290CCF16@hal.varese.it>

Hello,
i'm a fan of statistics, i want to know how many hits my sites have
received, from which country, how long, etc. etc.
I run several programs to analyze the logs from Apache and Zope but, i
don't know how to split the log files of Zope for different sites.
In my situation i have some web based only on Apache, as virtual hosts
where i can specify which log file to use for that single entry; some
are on Zope, virtual hosts done using SiteAccess and ProxyPass. Mine
problem is that i want one single different file for every virtual host
i have on Zope.
Is there a solution?
I also have problems with kill -hup, it doesn't work with python, so to
take the daily log
i have to stop Zope, take out the log and then start it again. Ok, it's
not a big problem, but that single minute of pause it's not making me
happy!

Thanks,
    Bruno

I'm running my dev-server (2.1.4) off my
win2k-box..(P2-400Mhz - win2k professional)
Usually, updating is close to instant, but occasionally i
experience 20-30 second hangs when updating.. Never thought
of it as a problem, though , as the machine is not a dedicated server
and i run a lot of stuff of it simultaneously (browsers,
photoshop,etc..)

This I cannot understand, what's new ;-)
I've mocked it up in the attached .zexp if anyone wants to try it out themselves.

I have a site with a subfolder. This is private and so has 'view' permission only to a 'user' role
and the usual 'manager' role.

I have a file, index_html in the mockup, in this subfolder, which includes an image called 'black'
from the root of the site. The root folder has 'view' granted to the anonymous user.

I added my users with the 'user' role, user1 in the mockup - password 'user1', to the subfolder's
acl_users . However, when I went to view the subfolder and logged in as user1, the page loaded fine,
except for the 'black' image. I was asked to authenticate again but the only way I could get past
this was to use user2, password 'user2', who has manage access to the whole site. 

This is really confusing as 'black' comes from the root of the site, which is viewable by even the
anonymous user, and viewing the black image on its own in another browser session, even using the
URL from the HTML generated for the subfolder index_html, worked fine and no authentication was
requested.

Obviously giving these users manager access to the whole site was unacceptable. I managed to solve
the problem, see user3 - password 'user3' in the mockup, by creating the user in the root acl_users
folder and giving them no roles. Then, giving them 'user' as a local role in subfolder.

I've tried this with Zope 2.1.4 and 2.1.6 on Linux and NT4, Netscape 3.04, Netscape 4.7 and Explorer
5.1 all with the same result.

Anyone know what's going on?

Chris

I had the same question, and found the answer in the code of the SQLSession

Message-ID: <B504CF1E.2EF1%Jatwood@bwanazulia.com>

I have set up a form for people to send an email to someone else from the
website. They put in a from and a to email address. It will take any "to"
email but if the "from" email address does not exist it returns the error

"Recieved error code 501 from SMTP: 501 ... Sender domain must exist "

I have used <dtml-try> but it does not work.

Anyone have another way to handle this error?

Thanks,

If you want to use pythonish expressions in a dtml-var tag, just quote
them.

e.g., <dtml-var expr="myStr[:4]">  will get you the first four
characters of string myStr.  The 'expr=' part is optional.

Hi there,

I'm trying hard to make my Oracle8i  (Oracle 8.1.5.0.1)  for Linux  on
Redhat 6.0 with Python 1.52 plus python-devel installed from rpms and Zope
2.1.6 talk to each other...


As I understand so far, I first have to

      build the extension modules used by DCOracle.

     Install the ZOracleDA


Right?

I tried the new Oracle8i  setup-file provided on www.zope.org, I also tried
both Setup-Files provided with DCOracle, but everytime the same.

By the way, I suppose that there is no problem with the Oracle
client-library setup, because I am already connecting to the Oracle8i with
PHP.
I've never had problems with Python installed from rpms? Did anybody else
have?

some additional data points on those crashes:

in my test setup (CVS checkout using ZOracleDA) i found the following
ways to avoid crashing:

- using Pavlos' cure (setting DEBUG=1 in asyncore.py)

- manually closing the oracle database connection or deleting it (which
renders the membership components of my site useless since all that info
is in oracle)

- calling the offending page directly in a python interpreter by talking
to ZPublisher and circumventing ZServer

my suspicion is some weird interaction between the database adapter and
ZServer.

How can this be fixed?  

I can probably figure out how to make sure libpq (postgresql API
library) is reentrant (it might be already).  What has to happen to
the DA to make this work?

And if this was done, could you configure the DA to open, say 5
backend processes and use them in turn?

Thanks for your input.However I'm not sure that i really understand it. I
guessed that in that method the key element is popertyMap. So I tried:
<dtml-var propertyMap> in my zclass_addForm.

When i tried to add a myzclass instance anywhere in the ZODB hierearchy i get:
({'id': 'title', 'type': 'string'},)
Not exactly what i wanted. I wanted to get the ids and types of the
propertysheets properties.

Here is the purpose. I found that the default method of adding ZClass instance
is boring. The form asks you to type the id, then you can add your instance and
after that go to the propertysheets/myproperty/manage method to fill the
propertysheets properties.

I think that most of the times it's better to fill these properties when you
create the instance. So i began to modify each time, the addForm to include
the propertysheets properties in its form. It worked fine but each time i
create new ZClass i have to modify manually the addForm. So i tried to create a
generic addForm that could work with any kind of ZClass no matter what are the
propertysheets properties.

That's why i wanted to get the ids end types of the propertysheets properties of
a ZClass from outside the ZClass.

I can do that by creating an instance, taking the needed information from that
instance to generate automatically the addForm, creating a new instance with
the addForm then deleting the instance from where i got the required
information about the propertysheets. It works fine but it's not very elegant
and may a source of potentiel problems. Here is a "addForm" code that works:

<form action="ebook_add" method="post" enctype="multipart/form-data">

    <td><input type=text width=25 name=id></td>

Yellow,

I don't know about all you but I'm trying to use MySQLdb  0.1.2 on NT4 +
SP6a + Zope 2.1.4
The Installation Instructions aren't to precise on using it on win32
platforms and Zope doesn't show me the MySQLdb on the product list. Is there
some special steps to install it on NT?
I've seen the instructions page on zope.org and I know about having to aplly
the patch and compiling the .py on unix systems.. but what about win32?

anyone?

To use the propertysheet before you have an instance, you need to get the
Product into the namespace stack, something like this (untested, but I do stuff
like this elsewhere)::

  <dtml-with "manage_addProduct[ 'MyZClassProduct' ]">
   <dtml-in "MyZClass.propertysheets.info.propertyMap()">
    ....
   </dtml-in>
  </dtml-with>

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Hi,

I've Zope 2.1.4 running on NT4.0, using ZServer.
I would like to set up IE5.0's "Web Folder" feature
for Zope, with Zope's authentication. I could set
up a web folder, but it doesn't do authentication,
so I can't've any PUT rights...

Any thoughts?

Thanks

You should be running Zope with -D option and no -Z option, ie not as a
deamon. Then you will be able to see the connections that come in and out.
Seems though that there are two (or more) problems.

I don't think I'm following you - what do you mean 
by "it doesn't do authentication"? After setting up 
a Web Folder pointed to a folder in your Zope 
installation, what happens if you try to drag a file 
from your desktop to the Web Folder?

Has anybody seen this before? I seriously doubt my maxusers setting is
the problem -- this usually indicates an infinate openfile loop. Anyway,
the short of it is that Zope isn't starting. I'm using FreeBSD 3.4 and
Python 1.5.2.

Thanks!

Oops!

Sorry, folks. Stupid IE problem. I don't know
what happened, but went to MS site, downloaded
5.01 and did a complete re-install, and it is
working fine, now.

Another thing - would it be possible
to've https for ZServer webDAV? I'm trying
to push Zope's use in my organization, and
right now, am toying with the idea below
(because FTP is ruled out by our security
guy).
  - Run Zope as a webDav server
  - IE5.0 as client
  - People who want to post content to the HTTPD
    server (which is IIS3), just drag and drop
    from their PC to the Web Folder.
Issues as of now:
  - How to get the content to NT folders rather than ZODB?
      localFS does not permit uploads... May be I'll try ZMirror.

I work for a non-profit organization and right now we are
not in a position to adopt IIS5 or NT2000. Nor do people
want to go for Apache + Linux. And I could'nt find out
any other affordable webDAV server for NT.

Zope has got lof of people excited in my workplace and
that is also one reason I want to push for Zope.

Subject: [Zope] Same name property for different propertysheets
Message-ID: <00032712571600.01015@modemcable215.47-200-24.mtl.mc.videotron.net>

In the Z Class tutorial (page8) I read:

"Property Sheets also allow more indirect access to properties via the
propertysheets attribute. ... we could access the 'title' property via
propertysheets.stuff.title attribute in addition to simply the title attribute.
The sort of access is handy in the case where two different propety sheets
define properties with the same name."

Sounds great, so I tried to use to it to create a sort of "international" class:

myClass:
    propertysheets
        english
            name
            description
            .....


but if i try:
myClass:
    propertysheets
        french
            name
            .....

i get the following werror message:
Invalid property id, first_name. It is in use.

So it seems that contrary to what suggests the Z Class tutorial it is not
possible to have two properties with the same name in the same ZClass even if
they are in different propertysheets at least when using the management tabs to
add a new property.

Is it a mistake in the tutorial or is there another means to add a property
with a same name in another propertysheet without getting an error?

I was just about to implement a similar method, and it occurred to me that I
would have to give a proxy role to the method so that it could add a user.
Have you tried that?

I do something very similar in the ZGotW product's root factory::

 <dtml-in "defaults.objectIds( 'DTML Method' )">
  <dtml-let si=sequence-item>
   <dtml-with newRoot>
     <dtml-call "manage_addDTMLMethod( si, '', defaults[ si ] )"> 
   </dtml-with>
  </dtml-let>
 </dtml-in>

The key here may be the inner '<dtml-with newRoot>', which is forcing the
newly-created root folder to the top of the namespace stack, so that
'manage_addDTMLMethod()' is being invoked on it, rather than on the
sequence-item.

Hope this helps!

Tres.

I have a timestamp, for instance, 2000/03/27 19:57:53.9808 GMT.

Lets say I have a document property, type date, where I want to

I found that the use of A or B is different:

A)

	<form action=manage_changeProperties>
	<input type="text:date" name="mydate" value=<dtml-var Prop1>
	<input type=submit>
	</form>


The difference arise when formating for presentation:

A)
	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 18:57

B)

	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 19:57

Note: the 1 hour difference.

	I guess the difference is in the "Prop1:date" that forces
zope to create the correct object with all the information needed to,
for instance, recognize the GMT change since March 26.

	I found that using another kind of presentation format will
bypass this problem, i.e, instead of fmt="c style", I use functions like 
dd(), mm(), timeminutes().

	Is there a way to make the code A tell zope to create a
correct date object(property)?

My best regards,
Júlio Silva

Subject: [Zope] Creating Python class instances via DTML
Message-ID: <38DFC3D2.92037BD3@www.ifopen.com>

Greetings,

	I have created a Python class (Lead) and added it as a product and
am able to create and edit instances via the managment interface.
However,
I have run into a wall when trying to do so via DTML. Taking the path
used
in the "Adding ZClass Instances Programmatically" HOWTO, I've tried
things
like:

	<dtml-with "manage_addproduct(['Lead'])">
	<dtml-call "manage_addLeadForm">
	</dtml-with>

where "manage_addLeadForm = HTMLFile('leadAdd', globals())" appears
within
".../Products/Lead/Lead.py" and "leadAdd.dtml" contains the form used
to populate the object fields. I continually get "NameError's" on
"manage_addLeadForm" so I'm guessing that I'm have namespace issues.
Can anyone point me in the right direction?

				Thanks, Bill

Sounds like you want to roll the results into a ZRDB Results object,
like an sql query results object.

from Shared.DC.ZRDB.Results import Results

I'd suggest that you take a look at Shared.DC.ZRDB as well as Ty
Sarna's TinyTable Product which does this in a more simplistic
manner.

One of my product has a LocalFS descendent class, where I can upload
files. Well I simply use a Zope file object for uploading, then I save
the content of the file object into a NT folder. If it helps you I can
send this code for you.

Is there a way to do this using Zope-zserver, and not Zope-pcgi?
When I started this, I was just using the Zserver....but now that I need
to include calls to cgi programs for the sake of a couple images, I am
thinking I will needs Zope-pcgi..

If this is the case, I will need to uninstall the Zope-Zserver (if I try
to have both, there is a conflict) and install Zope-pcgi.  Does this mean 
I will have to import all the files, directories, etc. back into Zope, and
then reconfigure all of the files (replace all SSI lines with
dtml lines, etc)?


Thanks,

Made no difference here either.

In desperation, I moved the server behind an apache using fastcgi. Same
problem persists...random crashes with aaiiieee 11 and 256 in the debug
log, often with core dumps.

May be time to move away from the Lintel box (stock redhat 6.1, 2.16 src
install, pII350, 256mB ram) - I don't see this on a sun box I'm also
running.

Does this happen with binary installs ? Is it just redhat 6.1 (we didn't
see this on 5.2!)? One problem is that the zmonitor usually works - the
server restarts itself and users may only notice a long delay. I see it
because I'm watching the logs anxiously.

True, I still get the restart problem. What the DEBUG=1 solved was the
mysterious exits without core dumps or debug notices under very little 
load (I cannot still grok why it would kill the monitor process too).
Under high load we still get crashes but at least now when it dies the
monitor process will usually restart Zope.

We are also running behind FastCGI but as you have experienced too, we
still get the crashes, at least every 5-10 hours sometimes more
frequently. (And we have no DB connections or any weird code.)

About to give up ...

MySQLdb is the python client (driver) for MySQL.  ZMySQLDA is the Zope
Database Adaptor which interfaces with MySQLdb to access the MySQL database.
As far as getting it to run on NT,  good luck.  

Under Debian the whole process looked like this:
  apt-get install ZMySQLDA

I let some poor Debian developer worry about how to configure the two and
make it all work.

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Well, I just moved my zope to a Solaris box rebuilt with gcc.  I'm now
able to CONSISTENTLY get this thing to crash.

What i do is point a couple of wgets at the box to recursively snarf
up pages.  This doesn't seem to cause any  problems (yet)

Then with my browser, I try and load up some pages.  Usually, within
four or five attempts at loading pages, BAMM zope starts eating up CPU
cycles and within two minutes zope crashes...

And this is what the debugger tells me:

Program received signal SIGSEGV, Segmentation fault.

Yes, at one point, in desparation, my method had all the rights I could
grant it :)  It turned out that you have to give the rights to the
object you're cloning, too.

Hm - what we need is someone running on Solaris who can get
crashes, who also has access to purify. We're moving from
linux to Solaris at the moment, and I'll be getting hold of
purify to try and track down this damn problem.

I did a search on the web and found out a few complains about programs
compiled with gcc seg faulting. One posting mentioned a faulty
implementaion of the pow() call, of course I have *no clue* how or why it
causes problems in Zope.

One more thing.
Can you try disabling multithreading by giving the option -t 1 to z2.py?

Good to be able to reproduce the problem. I suppose I can call it progress
...

Subject: [Zope] multipart content type
Message-ID: <38DFFDC2.AF2335FA@adroitnet.com.au>

Hi,

I need to get zope to server multiplart content.  The problem I have is
that Zope always puts its own header with a content-type,
content-length, etc on each RESPONSE.   Is there any way to stop zope
doing this?   This is a problem because the RESPONSE specifically needs
to look something like this:

        Content-type: multipart/mixed

--Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: application-compressed/zip

      {contents of .ZIP file, character for character}

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: text/html

      <html>
      <head>...</head>
      <body>...</body>
      </html>

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!--

I can set the content-type that zope returns by using
RESPONSE.setHeader, but i cannot control what else is put in the header,
and the order of the header attributes.  This causes a problem with
multipart messages because the boundary string needs to directly follow
the content-type: multipart/mixed, and the first message part
content-type needs to directly follow that.

Any suggestions?

Hmm... if you just want to check that everything is there, try
(untested):

<dtml-if "_.len(REQUEST.form) > X">
  render page
<dtml-else>
  go back and fix it
</dtml-if>

where x is the number of variables in your form.

Yes you can but it is more involved than the management interface. Can you
log in into the management screen of a different folder? Then you can undo
from there.

Yes and no :-) Your product's add method creates a folder object, then 
switches to it and adds the default methods with each appropriate add
method. What I was trying to do was add a ZClass based product with
the createInObjectManager method, then use manage_clone to copy my
default objects across. 

It turns out I was doing this from the right place (inside the
dtml-with that is used to create the object), but manage_clone is
broken - it let you copy objects into a thing you've just created
inside the same method at all. I'm pretty sure this is a bug - I'd be
interested to know if anyone has actually got this working at all.

In the process of testing this out, I discovered another piece of
unexpected behaviour - you can do this:

<dtml-with "manage_addFolder( rootID, rootTitle )">
</dtml-with>

...and you can then switch to using that object straight away, but if
you do this:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
</dtml-with>

...the object you've just created doesn't appear to exist as far as
the rest of your dtml method is concerned. 

So I've got something working, using the various object add methods,
but I need to make sure I have one for each type of object in my
default set, and I have a feeling that I'll need to recurse into
folders to add those and their contents. 

Thank,
John.

Just curious, but I am using a rewrite rule from apache (same things happens if
append the folder to the URL using site access) and the controls for the calendar
keep appending the root folder of the site. For instance, jobs.domain.com
correctly displays items from the /jobs folder in zope, but the calendar controls
keep appending jobs as I navigate the calendar like after a few times I get
jobs.domain.com/jobs/jobs/jobs/jobs/jobs/myCal.

Is there anyway around this?

I've written a mxODBC DA but can't even get off first base with testing it.

Arg! I don't seem to be able to add anything other than DTML methods
and properties inside a Zclass creation. So it looks like I'm back to
doing it all by had. What a time saver...

Graham

please correct me if I'm mistaken - having read the How-To it seems that it
only allows you to get at the *contents* of the files. All I need is a
pointer, a reference, to the file so someone can download it.

Anyway I tried it with the following:

<dtml-var standard_html_header>
<h2><dtml-var title_or_id></h2>
<a href="<dtml-var "support['brochures']['brochure.pdf']">">Test Doc</a>
<dtml-var standard_html_footer>

When I view this in the browser I get a 'Save to file' dialog, I duly saved
the file (it was an HTML file) and on viewing the saved file I can see that
it does indeed
contain the contents of brochure.pdf(!), which is not what I want.

To re-phrase my original question - how do I construct a URL in Zope such
that it can refer to a file on the local filesystem?

thanks

The traceback is in error_tb -- try <dtml-var error_tb>

Other variables that are defined for error messages are:

  error_message (may be null)

Take a look at /standard_error_message for their usage.

Subject: [Zope] Serving external files
Message-ID: <38E068A5.11CCAA4D@rrsg.ee.uct.ac.za>

Hi,
I have some questions about serving external files:

I want to be able to serve a file that is external to Zope's Object
database. This file would probably be a binary file. So far, I have an
external method that reads the data from the file, and sets the header
of the RESPONSE object passed to it. The external method looks something
like:
    def readFile(self, REQUEST, RESPONSE):
        ...
        data = f.read()   # where f is the binary file, and has been
opened
       RESPONSE.setHeader("Content-Type", "application/data")
        return data

The zope id of the external method is "getFile".

I have a dtml method that calls this external method, using
<dtml-var "getFile(REQUEST, RESPONSE)">
The id of this dtml method is "download".
Say I have a dtm document with something like
<a href="download">SomeFile.dat</a>

This works, and the file is downloaded correctly. I want to know firstly
whether there is a better way of achieving this.
Secondly, when the user clicks on the SomeFile.dat hyperlink, and the
browser's "save as" dialog pops up, the browser uses the id of the dtml
method "download" as the filename in the dialog. Obviously I would
rather this dialog shows the name of the file that will be downloaded.
How can I change this? I can't rename the dtml method suitable for each
different filname that might be downloaded, so where else can I alter
this behaviour?

Thanks
Allen

Take three. I've solved the problem for all cases by having the ZClass 
add method redirect to a method that copies the default methods into
the new ZClass instance, then redirects back to the management screen.

Might have to write a howto for this one.

<dtml-var ***> with an image object writes out a full <img
src=***>-tag..
Your html-will look like this :
background"<img src="myimage">"

write it out as straight html :
background=myimage"

the error you're getting is probably because of the faulty
qouting in the dtml-var-tag..

Message-ID: <v04205507b5061c302dc9@[130.227.115.56]>

Hi,

I have a simple question - how do I use the fmod function in the math 
module with dtml ?

I've tried something like this(and a lot of variants):

<dtml-if expr="_.math.fmod(x,y) == 0">
	do something
</dtml-if>



What is it for:

I have some words returned from a search which I want to be displayed 
like this:

word_a	word_b	word_c
word_d	word_e	word_f
word_g	word_h	word_i

Thanks in advance.

And with good reason, you have overlapping angle brackets, your expression should read

<body background="<dtml-var "myimage">"

or

<body background="<dtml-var myimage>">

but this won't achieve what you want. What you really want is:

<body background="&dtml.url-myimage;"> 

See http://www.zope.org/Members/AlexR/EntitySyntax for more details.

Allen,

Try looking at the LocalFS product available on the Zope.org site.

It makes folders on the physical drive look like part of the ZODB.

You need to recompile your kernel with an higher value for MAXUSER parameter
(x2 or x4 the current value).

MAXUSER parameter helps the kernel handle the load of the machine(max file
numbers, buffers, etc...). Python&Zope opens loads of files on the
filesystem, so the default value for MAXUSER is not enough.

Hope that helps.

Hi

The following snippet (tested) works as expected, printing the values in
three columns.

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('WordList', ['word_a', 'word_b', 'word_c', 'word_d',
'word_e', 'word_f', 'word_g'])">

<dtml-in WordList>
  <dtml-unless sequence-start>
    <dtml-if "_.math.fmod(_['sequence-index'], 3) == 0">
      <br>
    </dtml-if>
  </dtml-unless>
  <dtml-var sequence-item>
</dtml-in>
<dtml-var standard_html_footer>

Yes. Use the LocalFS product, it's taken care of a lot of the things 
that you're battling with (I've done the same thing and am in the 
process of moving to LocalFS).

Again, LocalFS will do this for you (my main reason for switching!).

Subject: [Zope] Is Zope suitable?
Message-ID: <000001bf989a$f08d97a0$1e01a8c0@tingeling>

Hello!

I have some questions about Zope and I thought I ask them before
spending alot of time reading the documentation.


Can I install zope on a apache system WITHOUT being root? My ISP is
running apache on a Solaris 5.6 system.

I want to create a system that lets any user create his own User Data
Record. The user data record will contain data about the user, e.g.
Name, email address, etc. This record should only be editable by the
user (and admin) with somekind of login. This user data must then be
searchable! Listings on all or some of the data should be able to
present in different sorting orders, e.g. Lastname, country, etc.

Is Zope suited for this kind of system?
Maybe someone already has created a system like this?

   You can, but would your ISP allow you to run Long Running Process? Zope
is LRP, you know, and many ISPs are very afarid of it.
   In any case you'd nned a support from ISP to setup a way their WWW
server will use to talk to your Zope installation - pcgi-wrapper,
mod_pcgi2, ProxyPass...

   Looks like a job for Zope Portal Toolkit; probably, you'd need to
extend it...

We made something like this with zclasses and regular user
folders recently, using a zclass to hold the
info, and dynamically creating users with localroles in
their own zclass-instance, allowing them to edit their own
information..

Not the best way if you expect a lot of writes to your
server,i guess,  but nice enough for small sites..

Thanks -
I have downloaded LocalFS, but haven't tried anything substantial with it,
my reason being that I needed to upload these external files as well.
A user must be able to upload a file, which will be saved to the local file
system, and made available for download from the local file system. The
actual path to the file will be stored in a relational database (along with
a whole lot of other info). If I were to use the LocalFS product for this,
is it possible to add a LocalFS object dynamically (through some dtml method
that gets called when a user uploads a file)? Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.

Any comments appreciated!
thanks
Allen

Thanks, this works perfectly. I don't know why my code doesn't work 
because I have tried the same thing as you have. But I must have

Yes, but just set up a LocalFS object from the management interface 
and don't worry about it. If you're worried about files cluttering up 
the filestore, use a cron job to wipe them out.

Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.


It uses python filesystem methods, so I reckon the number of files in 
a LocalFS object (ie the directory) is os limited.

I sent an email to the list on the 21st March where I had some 
(rudimentary) dtml and python code that uploads to a LocalFS object 
(ie the directory that the LocalFS object is pointing to). Check it

Message-ID: <REhvNZAilI44Ew7q@compkarori.com>

I couldn't see this covered in the Zsql user's guide.

select myfield from foo

works as expected.

As the current ODBC driver I am using has a bug which truncates varchar
fields, it was suggested I cast it to char while retrieving the field.

But

select cast(my_varchar_field as char(140)) from foo

gives an error with the following traceback...

I just found a HOWTO by jpenny: Accessing a ZSQL method from an 
external method. It helps a bit but actually I don't want to use a 
ZSQL method I just want to take advantage of a persistant connection. 
Wait, I got an idea ...

[20 min. later]
Hooray! Try this: I have an open ZMySQL Database called 
'my_connection'. Now I can query the db from my external method with:

self.my_connection._v_database_connection.query('select * from whatever')

[another 20 min. later]
I benchmarked it agains opening a connection and cursor and then 
execute() and fetchall(). Using the Zope connection took about 60% of 
the time the other method took.

I wonder if there are any disadvantages???

Synchronicity!  I've just read the same document today and found the python
code for database connections (in ./lib/python/Shared/DC/ZRDB/Connection.py,
if anyone is interested :-), and am about to try passing my own queries in.

> I wonder if there are any disadvantages???

The only one I could immediately think of was "what if the database
connection hasn't been opened".  I can see the method for
manage_open_connection() (and _v_connected/connected() for the status
of the connection), but don't feel 100% comfortable calling Zope
internals just yet.  Any caveats for just semi-blindly calling
.manage_open_connection() if .connected() returns false?

Subject: [Zope] Problems with ZCatalog-indexing
Message-ID: <Pine.GSO.3.96.1000328140758.20415A-100000@nausikaa>

Hello all,

I've got some problems with indexing in ZCatalog.

First of all it doesn't seem possible to index words containing any
non-ascii characters (most important german umlauts). On zope.org the
only info on charactersets I found was, that there are some supported
ones, but I couldn't find out which these are.

How is it possible to have a correct indexed catalog on a german site ?

The second problem is related with the first one, but not restricted to
german characters.
Words where a hyphen appears, e.g. names like 'Hans-Dietrich', aren't
indexed at all, in the example 'Hans-Dietrich'
cannot be found on the site, but 'Hans' or 'Dietrich' cannot be found,
either.

If I cannot fix these Problems, the ZCatalog is unusable in the site, as
there are a lot of important keywords using umlauts or containig hyphens.

Thanks for your help,

Tobias Kiesling

You should use a recursive mathod.

Write one method recursiveMethod:

def recursiveMethod(obj):
     result = []
     if obj.parent != None:
          result = recursiveMethod(obj)
     if obj.meta_type=='KBItem':
          result.append(obj.Title)
     return result

Then call this method like:

def GetParentNames(self):
     recursiveMethod(self)


This code is untested, but should work.

Stephan

I'm glad you found a workaround.  Just offhand, did you try to just call that
additional method, before redirecting to it?  I have seen a couple of cases
where I refactored code like that into a new method and then things got simpler.

We're phasing out hosting in favor of DASH (Dedicated Application Server
Hosting). This is not a price quote: For about $200/mo, you can get a
Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT for
some reason, there's an HP box available. For more details, see:

Hi,

I'm in the process of cleaning up our production Zope server and I've found a folder which has one
file in it. I don't know who created either of them and I'm wondering if they're redundant.

I'd like to find out who created the both the folder and the file and, if possible, when it was last
created. How do I go about doing this?

Cheers for any help,

Subject: [Zope] Newbie question - product embedding
Message-ID: <38E0C7B5.38276033@advis.cz>

Hello,

I am just evaluating the Zope system, and it looks good. I am trying to
build an example Intranet site, using Squishdot.
I need a poll embedded in one of the Squishboxes.

I tried both PMPPoll product and Poll product, but cannot get it to
render into the page.

I have a DTML method calling the poll object like this


... some simple HTML ...
<br>
<dtml-var name="my_sample_poll">
<br>
.. some more simple HTML ...

The simple HTML indeed appears in the box, but instead of the poll form,
which I expect to be rendered, I get the following in the page source :

<br>
<Survey instance at 8635589>
<br>

Am I missing something obvious? Should I call the object from within my
DTML method some other way? Thanks for your help.

Hi,

Yes, this gives me parents, but it doesn't work for my problem :

The external method is used for storing the information into a ZCatalog.
Now, when the Catalog is updated, I get the wrong parents, I get the
parents of the catalog and not of the object itself. :-(

Somebody another idea?

Tom.

I tend to agree with Tres here. MySQL can certainly handle BLOBS, but
here's something you might not realize: All MySQL queries are literals.
Let that sink in for a moment. What does this mean? Suppose you are
using MySQLdb (not a ZSQLDA, we'll get to that). You need to do
something like this:

c = db.cursor()
c.execute("INSERT INTO BlobCity (Pix) VALUES (%s)", pix)

Looks simple, doesn't it? Well, here's what happens behind the scenes.
First MySQLdb has to turn pix into a MySQL literal value. Fortunately, if
you have, say, a JPEG class, you can write a function (not method) which
converts it into a MySQL literal. Suppose your class has a __str__ method
which returns the raw data as a Python string (maybe it IS a string
internally). Then you can do:

def JPEG2Literal(j): return "'%s'" % MySQLdb.escape_string(str(j))

(Although this is actually the default converter, used for strings; if you
have a __str__ method, you can just pass it to MySQLdb and it should do
the right thing.)

MySQLdb.escape string does all of necssary escaping of special characters,
namely backslash, NUL, and single-quote. But to do this, it has to
allocate a temporary buffer that's twice the size of the original string
to handle the pathological cases. Then quotes have to be added. Then this
all has to be inserted back into the original query. In the case of a 5 MB
BLOB, these steps work out to be:

1) str(j): 5MB
2) escape_string(#1): intermediate 10MB, return new 5MB+ string
3) "'%s'" % #2: return new 5MB+ string, but del #2
4) querystring % (#3): return new 5MB+ string, but del #3

So you're making and destroying a lot of big strings, which takes a
considerable amount of time. And we're only using one column and one row.
(I should probably make a new C function that combines #2 and #3 for
efficiency.) Most of what MySQLdb does is string crunching. For that
matter, MySQL returns all values to the C API as strings (including
numbers).

And now the Zope ZMySQLDA case: Z DA's always build literal queries
anyway, so this makes MySQL no worse off than any other database. (Most
database APIs, like ODBC, seem to use positional placeholders in the query
and pass the rows/columns as a data structure, which makes for much less
parsing on the server side, and is much easier to construct on the client
side.)

Compare this to writing into the filesystem. Well, no comparison, really.
open, write, done. So long as you can keep things organized, you're ok.

MySQLdb is not a Zope Product; it's a Python module. ZMySQLDA is the Zope
Product. It needs to be patched to work with MySQLdb, however. I have no
idea how you would do this on Windows. Only the Python code (no C code)
needs to be patched. Stay tuned...

Ok, now I found the error. The error must be in the while loop, where we
say 'iterate until the obj = None'. However 'None' is never reached... (I
guess). 
The following code works, but I this isn't at all a good solution. 

Can someone tell me how I can safely test that the current object is the
first object in the object database. In other laguages you can test this
with 'nil'. How can I test this within Zope? Please, tell me!

def GetParentNames(self):
  result=[]
  obj=self
  while obj.title != 'Zope':
    obj=obj.aq_parent
    if obj.meta_type=='KBItem':
      result.append(obj.Title)    
  return result

Thanks in advance,

You must your locale environment variable correctly.  See 'man locale'
on linux, for example.  Also, you can pass z2.py the -L argument to
explicitly set a locale.  This will allow you to index german
characters.

Hyphens are hard coded in the text index to split words.  This is
because the text splitter is not very flexible and is very english
centric.

To fix this, you must either 1) create your own splitter, 2) update to
the latest CVS and create your own vocabulary and provide a new
splitter.  

The CVS version of Catalog is much more language neutral, and there are
now two kids of vocabulary object, English and Globbing-English.  Soon
someone I'm in contact with will be providing a Japanese vocabulary.  If
you have the patience, you should developer a German vocabulary to
address these issue.

Sometime between when your catalog was generated and when you tried to
re index the content you updated your CVS sandbox.  When you did this,
you got the new catalog code that doesn't work with old catalogs.

This non-backwards compatability has since been fixed.  If you update
your CVS to the most recent version this error should go away.

Let me know if it doesn't.

I think this would be a useful addition to the Zope core...I find
myself doing the same thing and I've been thinking about developing
the generic add form but haven't had time to even start it.

This works for me:

<dtml-with right_poll>
  <dtml-var index_html>
</dtml-with>

Of course you'll have to modify the poll's index_html document to
remove all of the full page stuff because you only want a table cell
for rightbox items.

Hi!

First of all I've to say that I'm a realy beginner in Zope.
I recently updated from 2.1.3 to 2.1.6 and noticed following problems:


In 2.1.3
<dtml-with "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
  <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
  </dtml-in>
</dtml-with>
 works great

In 2.1.6 it produces an Error message that
title, empf_sem, diplompruefungsfach is not known by the system
(I already Posted that)

Now I found out that
<dtml-call "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
 <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"_.getitem(REQUEST['fach'],1).propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
 </dtml-in>

works fine in 2.1.6. (getSubjectInfo is a SQL Method)

Has someone a hint for me?

Helmut.

Subject: [Zope] RE: ZCatalog Indexing
Message-ID: <38E0EC1E.7DBC7011@hiretechs.com>

Tobias,

The Catalgo uses a stripper to make the indexes smaller. It doesn't
index =-+*&)(^%$#@. etc... or numbers.  Some words too like 'Bill'. From
what I've been told there is a version of the Catalog on it's way which
will allow you to put keywords or charaters in a special place that will
include them.  I couldn't wait for that, and I love Zope, so I came up
with a major kludge.  catalog_quote() and catalog_unquote().  They are
from an External Method which I wrote catalog_quote.py.  Here it is:


from string import strip, split, join, uppercase, lowercase, find
bad_characters=(('.'),
                ('+'),
                ('-'),
                (';'),
                (':'),
                ('&'),
                ('*'),
                ('%'),
                ('#'),
                ('@'),
                ('$'),
                ('0'),
                ('1'),
                ('2'),
                ('3'),
                ('4'),
                ('5'),
                ('6'),
                ('7'),
                ('8'),
                ('9'))

def catalog_quote(self, ascii):
    text = str(ascii)
    for re in bad_characters:
        if find(text, re) >= 0: text=join(split(text,re),ordinalize(re))
    return text

def ordinalize(letter):
    number = ord(letter)
    number_string = str(number)
    myletters = lowercase[-5:] + uppercase[-10:]
    converted = ''
    for character in number_string:
        converted = converted + myletters[int(character)]
    return converted  + 'g'

def catalog_unquote(self, ascii):
    text = str(ascii)
    for un in bad_characters:
        if find(text, ordinalize(un)) >= 0:
text=join(split(text,ordinalize(un)),un)
    return text


I just use it to turn anything that might contain the charaters in
bad_charaters into catalogable stuff.

Then when you search, you must catalog_quote() your search strings, and
you'll get 100% accurate results.  Hope this helps.


All my best,

Subject: [Zope] ZClass Icon broken when ZClass moved.
Message-ID: <3.0.5.32.20000329041128.009adc20@mail.skinnyhippo.com>

I had a ZClass (InnerClass) which was defined within
another ZClass (OuterClass) as follows :

/Control_Panel/Products/MyProduct/OuterClass/InnerClass

And a great many instances were defined with both
the OuterClass and the InnerClass. However, in order
to catalog the InnerClass (it is not CatalogAware 
and I do not want it to be), I need to move it to

/Control_Panel/Products/MyProduct/InnerClass

in order for 'InnerClass' to appear in the select
list ('Find objects of type') under the 'Find items
to ZCatalog' tab of the ZCatalog.

So far, so good. I moved the class and now can 
catalog it. However, now the icon is broken on all
of the instances of the 'InnerClass' ZClass. I 
have tried adding a new icon under the 'basic'
tab of the ZClass definition, but that doesn't
help either. I know it's just a petty icon and
it doesn't affect functionality but I'd really
like to clean this up so any clues/help appreciated.

Thank you very much,

chas

Hi all,

This code results in a error:

<dtml-let MyVar="_.string.replace(Mytext,'"','&quot;')">

I know its because of the quote in '"' because that cause in
same way an error when the "dtml parser" is parsing the code.

I've tryed to use '\"' and even _.chr(34) instead of " but the former gives 
me the same error and the latter dont give a error but also
dont do the string replace I want to do.

Any help?
Thanx,
Julio

This one goes especialy to ho write zope.

I have found that the dtml-in has a problem when you specify a batch-size that is less than the double of the length of the input list.
Ex.:
a list of 6 itens:
when size is 3, dtml-in returns 3 itens, correct. (3*2 <= 6) = true
when size is 4, dtml-in returns 6 itens, error. (4*2 <= 6) = false

Is this a bug?

Adding an "orphan=0" tag inside the dtml-in should do it:

  <dtml-in foo orphan=0>
    . . . bar . . .
  </dtml-in>

A more general question for the list, though:  Shouldn't the default
orphan value be zero?  It seems to me that if someone explicitly says
"I want three items," it should be more of a special case that they'd
somehow want more . . .

Opps. It works, but my sugestion of using _.chr(34) also works.
I was looking at the wrong results when testing _.chr().

Tried that - I in-lined it on the list for brevity's sake. The problem
is definitely with manage_clone not wanting to be used on a thing
inside the transaction that creates that thing.

This works for me (tested right at the moment with Zope 2.10)

This must be simple, but I haven't found it in the docs.
Can I get ZopeTime to give me the date, say, 20 days ago ?
Or a month ago ?
Something like (yes I know this won't work) 
<dtml-var expr="ZopeTime - 20")

One thing you need to keep in mind is that dtml-in has an orphan
attribute that determines the minimum amount of items to print out.  If
orphan is set to 3 (default) and you have a list of 6 items, and you set
size=4, the dtml-in tag will realize that 2 is too little to have on one
page and so it displays all 6.

If you don't want this, set orphan=0 in the dtml-in.

Subject: [Zope] BASE tag on File objects
Message-ID: <m38zz23a9e.fsf@wacko.pdx.net>

I've got a number of static HTML files on my site that Zope keeps
putting BASE tags into.  IMHO, it is inadvertantly appending a slash
onto the end of the HREF.  For example a file called default.htm in
the classified directory ends up with a base tag of:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm/">

I would think this should be:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm">

So I have modified: OFS.Image.File.index_html to strip the trailing
slash by adding:
        # clean up the base if neccessary
        if( RESPONSE.base[-1:] == '/' ):
            RESPONSE.base = RESPONSE.base[:-1]

What think you?

This should work:

<dtml-in SQL_ViewMember>
  <dtml-with Eligibility>
    <dtml-var MemberInfo>
  </dtml-with>
</dtml-in>

There could be a way with zserver but I don't know it. My advice is to
use PCGI for performance and salability anyway, though. ZServer is
quicker to setup, but in a production environment, apache is still
higher performance.

Although, having CGI scripts are never good for performance. ;) PCGI
is fine though.

You can generally have both pcgi and zserver installed without a
conflict; there's just no point to it. There very well could be a way
to "wrap" CGI scripts in zserver, but it would still be better done
in a true apache environment, where it belongs. To be 100% ZOPE you
would re-implement everything in Zope/Python/DTML though. I've seen
a lot of company areas where zope stuff points to CGI stuff and visa
versa, so your situation seems to frequently be solved that way.

You only need Zope-pcgi if the cgi calls need to come off of the
same IP as the rest of your zope.  If your Zope site is, say,
www.mysite.com, then you could put your image cgi stuff into an
Apahce responding to the an IP under the name of, say, images.mysite.com.
This would be your maximum performance route: direct calls to
Zserver for the Zope stuff, and direct calls to Apache for the cgi
images.

You only need the separate IP, by the way, if both need to be listening
on port 80 (say because people from behind a firewall need to access
your site).  If you can deal with either one listening on another
port, then Zope at least can deal with that (I imagine Apache can too,
but I've never tried it.)

> If this is the case, I will need to uninstall the Zope-Zserver (if I try

What have you run into that makes you think there is a conflict?
When you run Zope using pcgi, you are still running Zserver.  It's
just listening to pcgi calls instead of port 80 (or whatever) calls.
It is certainly possible to run Zserver such that it will respond
both to direct calls and to pcgi calls.  This is the way it is set
up by default, at least under Unix if you compile Zope using
w_pcgi: Zserver listens on port 8080 for http traffic, and also
communicates with Apache using pcgi.

Reinstalling to add pcgi support is like upgrading to a new version
of Zope: copy your var directory (actually just Data.fs should be
enough) to a safe place, do the install, and then copy your saved
var overtop of the new one built by the install.  You'll also need
to reinstall any Products that you downloaded and installed.

Hi,

I am looking for a translation engine (similar to Babelfish) that can 
be fully integrated with Zope. The only option I found so far is 
GPLTrans, which is based on PHP. Before I start porting it to Zope: 
is there anyone else out there already working on a similar project?

Anyone interested in helping out with such a project? Have a look at

   http://babelfish.altavista.com/
   http://gpltrans.sourceforge.net/

to see what I am talking about. Results to be released under the GPL.

Thnx,
Jonathan

Hi,
How do I import a module - I've been reading the DTML guide, and I would
like to use some of the functions described in the string module, but
how do use them - do I have to import the module (if so, how), or what
else. What I want to use is the following:
<dtml-if expr="lower(somestring)=='supplier'">

</dtml-if>
where lower is defined in the string module. I've also tried
string.lower(...) but that didn't seem to work.

thanks
Allen

I don't think you'd need any Zope products or additional code for a basic
implementation of what you want to do.

Just create the folder structure you want to have in Zope. Then you can add all
your documents with the management interface. To create the directory view, you
only need an index_html DTML Document that lists the folder structure (either
using the tree-tag or some dtml-in construction). 

For higher performance, you can use the ZCatalog to index the folder structure
and use code similar to the one on Zope.org to list the topic pages (e.g. all
the news on the Zope.org news page and all the products in the download area
are collected from the site using the ZCatalog.

I wouldn' use MySQL for that particular task because it fits the ZODB (Zope
object Database) perfectly (many reads, few writes).

You could also look into some of the products on the download page. I recall
that there might be some "out-of-the-box" directory solutions.

I'm finding myself again trying to figure out how things work in Zope, just

undocumented! Or maybe I just haven't looked for it enough ...

Isn't there somewhere a list of all method calls I can use from DTML (like
manage_addXYZ)? It can't all be just trial and error or "read the code". -- Yes
it can, but I don't want to be that pessimistic ;-)

O.k., my current problem is that I have a folder with icons and images in a
ZClass that should be copied to all new instances of the class.

There seems to be a "manage_clone" call for that (just read about it in a
posting), but how does it work and where do I find any documentation on it?

As all those methods are in the namespace, isn't there at least a trick to get
a list of all names to print out? That would be a first start.

I mean, I had to figure out every single call like manage_addDTMLDocument or
manage_changeProperties by trial and error. That makes Zope so much less
efficient that it could be ...

The string module is already available, just not as you'd expect ;)

Try something like:

<dtml-if expr="_.string.lower(somestring)=='supplier'">

</dtml-if>

You could also try <dtml-var "Eligibility.MemberInfo()"> although this might to use the namespace

from the zqr: 

manage_clone(ob, id, [REQUEST])
           Clone an object, creating a new object with the given id.

have you tried :

<dtml-var "Eligibility.MemberInfo(_.None,_)">

- just might do what you want..

Don't ask me about the specifics of what  (_.None,_) does,
though.

Subject: [Zope] passing arguments from dtml methods to SQL methods
Message-ID: <38E1D121.D5689279@rrsg.ee.uct.ac.za>

Hi,
Thanks for previous help on the namespace variable '_', much
appreciated!

I have another problem though, how does one pass parameters between DTML
methods, and from dtml methods to ZSQL methods?

I have a DTML method "getSearchResults" that gets called when a form is
posted using
<FORM... action="getSearchResults">
<INPUT NAME="fname"
</FORM>
The method gets called and magically the form fields like fname
described in the above form are accessible from the dtml method, so I
can do <dtml-var fname> and there's the input from the user. (I still
don't fully understand how that bit of black magic works...)

Ok, then I have a ZSQL method with fname as an argument, and again, when
my dtml method calls the zsql method, that variable fname can be
accessed using <dtml-var fname> in the SQL query. While maybe I don't
completely understand what's happening, I can still use it. The problem
now is, my ZSQL method needs to have an argument "tablename" that it can
use so that a different table can be selected, however, this tablename
is not under the user's direct control. It gets set according to some
choices that the user makes along the way. I would hence need to
"declare" it in the dtml method "getSearchResults", initialise it, and
pass it to the ZSQL method so that the ZSQL method can use it. I tried
doing the following: (suppose the ZMYSQL method's id is "searchMySQL").
in the dtml method:
    <dtml-if expr="whatever">
       <dtml-var name="getSearchResults(fname=fname,
tablename='suppname')">
    </dtml-if>
So that didn't work, but maybe it describes what I'm trying to do - that
is, fname exists and is initialised from the user's form input, but
I want to create the variable tablename, and pass it to another method
(or just create in the namespace space so that it's accessible to other
methods).

Sorry to be so long-winded, trying my best to describe things with my
very limited knowledge of zope/python.

Many thanks
Allen

Hm, is it - if it's undefined? 

what about (taking the function from one of your previouw posts) (only
lightly tested):

def recursiveMethod(self, obj, result):
    try:
     if obj.aq_parent:
           result.append(obj.title)
           recursiveMethod(self, obj.aq_parent, result)
    except AttributeError:
        pass
    return result

This is less elegant than testing for the attribute aq_parent, but
either hasattr is not allowed for External Methods, or ac_parent is not
an attribute.

Note, however, that if an object has no title it may also throw in an
AttributeError, thus aborting your method in too early. You could try
and catch this exception separately, but perhaps it shouldn't happen
anyway.

One small addition: I threw out the test for KBItem (because my Zope has
no such items), you can put them back in at line 4. Sorry for posting

Is there an easy way to test whether a value exists in a SQL table, so
that I can do something like this in a ZSQL Method:

<dtml-if> 
   [here follows the test for the existence of a value in a table]
   insert items into table
</dtml-else>
   update item in table
</dtml-if>

This problem probably came along before on the lists, but I can't find
it anymore...

Try using a COUNT in your SQL select formula. 

e.g.

Select count(colname) from tablename where colname='myvalue';

If it returns a 0 then that value doesn't exist.
If it returns anything then that is the number of times the value exists.

How about

<dtml-in "sqlFindItem(item=itemid)">
  <dtml-if sequence-start>
     do insert
  </dtml-if sequence-start>
<dtml-else>
     do update

Is it possible for zope to separate control from data automatically?

To make the best use of Zope, it will be necessary to separate the data and
control.

with XML, DOM will assign id for each node and thus  all of them can be
refered by that id.

Is it possible for zope to perform this? Will a modify of  load_site able to
do this semi-automatically? (run load_site over an existing zope tree?)

Message-ID: <Pine.LNX.4.10.10003291331390.19425-100000@oeh.tu-graz.ac.at>

if you want to pass variables to a dtml method you have the option to
set it in the REQUEST object eg.

  <dtml-call "REQUEST.set('varname', 'somestringval')">

or put it in the namespace eg.

  <dtml-let varname="'somestringval'">

then call your method as per normal eg. <dtml-var yourmethod> which
then will find the vars you set before.

or you call your method with keyword args like

  <dtml-var "yourmethod(_.None, _, varname='somestringval')">


note the difference between 

  <dtml-var "method"> which is <dtml-var expr="method">

and 

  <dtml-var method> which is <dtml-var name="method">


see the "Document Template Markup Language Reference",
http://www.zope.org/Documentation/Guides/DTML and the zope howto's.

Salutations,

I've been staring at this one for a while, but I can't quite seem to
pull it off.

I'd like to render a document based on the contents of a variable.
For example (simplified):

<dtml-call "REQUEST.set('foo', 'index_html')">
<dtml-var foo>

should (would? could?  I'd like!) render index_html.  Double
quotes don't cut it (both print the string 'index_html') :-(

- Because PrincipiaSearchSource (which is probably what you
are using for your full text search) is a property(method?) of DTML document and
method, but not of your new product..

try making a pythonmethod or external method (pythonmethod
is simpler) inside your
Zclass containing something like :

   return string.join((self.yourAttribute1, self.yourAttribute2, self.yourAttribute3), '; ')


where yourAttributeX are the attributes of your Zclass..add
as many you like...

name it PrincipiaSearchSource if that's what you're using
for the full text search.. (might be 'raw' too...)

Hi,
Thanks again for the help with the let and with tags...

I am making slow progress, but now can't seem to display my results from
a ZSQL method. How are the results returned? If they are in some
RESPONSE object, how would I read the items out?
So far, I have an SQL query which I'm fairly sure is working, and whcih
when tested gives the results I expect, but when I use it in the
following bit of DTML, nothing is rendered at all:

<dtml-call "REQUEST.set('cmatch', 'sup_name')">
<dtml-var searchMySQL>

The <dtml-var searchMySQL> line returns nothing, even though I know that
there are results for that method.

Apologies if I'm missing something I should be picking up from searching
the archives, but at the moment our connection is bogged down with lunch
time traffic, so I can't even get to the zope site.
thanks
Allen

No biggy..

<dtml-in searchMySql start=query_start>

<dtml-var variable_name>

</dtml-in>

That should get  you started but you should read the ZSQL Guide as it 
has lots of options that you can include (size, orphan, start 
sequence, end sequence, etc)

Really is worth the read.

Bear in mind you may have two pythons running on your machine.. the 'normal'
python that appears when you type 'python' at the command line, as well as
the python that zope installs. It may be that PIL is only in the path of the
former and not the latter.

In my case, 'foo' must be a string, and is actually passed in via

Message-ID: <38E22874.727DD231@wildenhain.de>

Hi,

browsing thru Shared.DC.ZRDB.Results i found this construct:

-------- line 117 ------------
		if not name:
			raise ValueError, 'Empty column name, %s' % name

------------------------------

This looks a bit silly, because if name is empty, %s will be replaced
with
nothing...
Furthermore, would it not be better to provide a generic name for the
empty column? Sure, it is difficult to provide such a name who does not
collide with others in namespace, but it would be very helpful, if the
underlying database-adaptor does not provide full names under certain
circumstances, such as ODBC with CenturaSQLBase always returns
empty column names to Zope with the count() Operator. Even if used "as"
to rename.
How about something like:
		if not name:
			name='column%d' % i

or such?
Next there is always some hassle with those 'table.column' columns
returning from databases who do not support column renaming.

Would it be a way to rename them automatically to something like
table_column? Yes, I know there could be a column already beeing 
called so. But if one knows she can use table.table_column in such
circumstances.
May be as alias?

I'm coming in late on this thread, so ignore me if this

It sounds like what you want is something like the following:

# docname is the variable passed in via the POST whose
# value is the name of the document to render. We use
# _.getattr(this(), docname) to retrieve the needed 
# document from the current object. Note that we use

# increasingly considered evil :)

<dtml-let theDoc="_.getattr(this(), docname)">
  <dtml-var theDoc>
</dtml-let>

Subject: [Zope] Problem with SQL+Special chars...
Message-ID: <B507F9A6.5E85%owrede@khm.de>

I am having a problem with HTML entities.

I am using Zope to enter and output text into a MySQL Database.

When I output the text, it is rendered through my own External Method:

   <dtml-var "myMthod(myText)">

I tired to write a little subrouting which is supposed to translate special
chars in the database into HTML during output.

Unfortuneatly the texts are entered on both MacOS and Windows browsers. This
unfortunatly makes it difficult: There is no unique ASCII code in the
database -- in other words: the same special char may be represented in the
database with to character values.

First I looked if the <dtml-sqlvar ...> had anything to offer, but that does
not seem to be the case.

How can I store text in ISO-Latin into the database regardless the Text is
entered via a Mac-Browser or a Windows-Browser?

Message-ID: <38E22FB4.7C8FFF18@nipltd.com>

Can you do colour in structured text?

The reason I ask is that I've just found out how great ZWiki Webs are but I'm wondering if there's a
shorter way of changing text colour than:
<FONT COLOR="#xxxxxx"> </FONT>

I'm looking to use a Wiki so a group of people can edit a web of documents and I was hoping that
each person could use a different colour. Having to do the colour by hand defeats the simplicity of
a Wiki :(

Any ideas?

Subject: [Zope] Mac2ISO conversion?
Message-ID: <B507FECC.5E86%owrede@khm.de>

I need to enter text data into a MySQL database via HTML forms.

Text entered on a Macintosh client is not ISO-Latin as it seems. When
getting that text out of the database, the special characters are broken in
the HTML page but not in the textarea.

Text entered via a Windows browser are not broken in the Mac browsers HTML
page - but in the textarea.

So I guess I should care for getting ISO-Latin text from the Mac clients
into the database!

From other areas I know this requires a mac-to-iso translation (in both
directions (because the text must be editable on Macs).


But how can I do this in Zope?

I know how to figure out, if it's a Mac-Client -- do I have to create an
External method fr this?

Hi,

I'm doing a back link to go on a page (yes, I know browsers have back buttons, but some people don't
like to use them ;-) which is easy enough:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>

except that if there is no referer, you get a key error. So I thought I'd try the following:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>">Back</A>

But I still get a key error. I thought the 'missing' attribute was supposed to catch that?

   Not quite. You are tripping a key error here so that won't work. Try:

<dtml-if "REQUEST.has_key('HTTP_REFERER')">
   <dtml-var "REQUEST['HTTP_REFERER']">
</dtml-if>

It still exists, in a very domant stage.  The next Zope release will
probably break it right out.  There's not much you can do with ZTables
that you can't do with the ZCatalog.

Subject: [Zope] building/exporting site and server question
Message-ID: <4.2.2.20000329111442.00a63b10@mail.bowmansystems.com>

I am relatively new to Zope, and I am working on a personal project at home 
on my Win98 box. I am just now getting the "zen" of Zope as everyone refers 
to it, and am building a true functional application.

So now that I am getting comfortable with Zope, here is my question. I am 
wondering if I can build my site/application on my Win98 box at home, 
export it out and then import it into another Zope installation running on 
another operating system (either BSDI or Linux). I am thinking I will have 
to buy my own server so that I can let Zope run as the server itself -- our 
servers up here all run Apache and I doubt our systems administrator up 
here would want to take the time and effort required to get that running 
properly (plus those are production servers, not really for employee 
projects!).

Is it possible and/or recommended to build a site/application on one 
installation and import it into another? Or should I just go ahead and by a 
box, put Linux on it, and proceed to build it on that platform? My concern 
is spending a lot of time building out the site on my home box and then 
finding a show-stopping hitch in the migration to another 
platform/installation.

Anyone who has had any experience with migrating Zope applications to other 
platforms/installation please reply so that I can make an informed decision 
as to how to proceed.

And also is there any reason to use Apache instead of letting Zope run as 
the server itself -- this will be on my own server so I doubt there will be 
much else on the box then my personal project and my home site (two virtual 
domains).

Thanks in advance.

This counts only for something like <dtml-var ought_to_be_missing
missing>
In your case you are inside Python when calling with " ".
So "missing" cannot catch this exception.
(Actually this simple <dtml-var .. > does much magic :)
So in your case you should do:

<dtml-if "REQUEST.environ.has_key('HTTP_REFERER')">
	<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>
</dtml-if>

This has the advantage of no blind link if there is no HTTP_REFERER set.

The reasons I came across were if you wanted to use SSL or have a site that
is half Zope, half Apache. Otherwise for simplicity sake ZServer by itself
is a great option. It is certainly the fastest and easiest to set up.

I decided to swith the roles, as I have ZServer running on Port 80 and
Apache on 8080 to sever up statistics, documentation docs and other very
static and non-production things that would be difficult to get into Zope.

As for the W98 migration, I would say develop it on the box you are going to
use it on. In the long run all the experience you get on the development
will not transfer to another OS. Linux is a great way go.

Btw. this works:

<dtml-with REQUEST>
  <dtml-with environ>
    <dtml-var HTTP_REFERER missing>
  </dtml-with>
</dtml-with>

or 

<dtml-with "REQUEST.environ">
    <dtml-var HTTP_REFERER missing>
</dtml-with>

if you want :-)

If you are experimenting with WIN 2000 try creating a NETWORK MAPPING
(WEBDAV) to a ZOPE FOLDER.

1. Click on Network
2. Click on Add a Network Place
3. Enter the url to a ZOPE Folder
4. Done

You now should have a folder view in Windows that Maps to a Zope Folder.
Enabling all sorts of great things:

1. Editing and Saving back to the folder with Security
2. Drag and Drop assets into the folder with Security

Great work on the Implementation of WEBDAV!!! Thanks DC!!!

That's very good news! Unfortunately I haven't been able to 
install win2K yet to see how it worked - I know about one 
further tweak that a little microsoft birdie told me I could
use to enable editing of "unprocessed" source (i.e. double 
click on a DTML method from a web folder and have it open 
unrendered in your chosen text editor or something). It 
shouldn't be hard to add, I just need to get the time and find
a box that I care little enough about to put w2K on it... :)

They do not offer "normal" PHP as an option -- you could ask them if they would
quote it as a "custom" add-on.  With enough work, it might be possible to call
PHP through a Zope product;  I don't know enough about what support PHP requires
from the OS and environment to know if this is feasible.

Of course, I also can't think of any reason to use PHP, but that is another
issue altogether. :)

Hi All!

Ok, just in time for my new nervous-breakdown, read this:

I have a ZClass which does have a "render" method.
The render-method collects items from a catalog and calls these objects'
"render" method.
Unfortunately this raises an Unauthorised Error, whenever I do not use the
super-user account.
(Zope has encountered an error while publishing this resource. 

Unauthorized

You are not authorized to access render.

Ok, so I gave the calling Method the proxy-role of the Manager. No change.
The strange thing about it is, and that is what puzzles me, that it works
for another class (which does only slightly different things).

So, what now, hu?

Regards, Ingo.

Do you mean site usage statistics (page views, etc.)?

If so, how do you measure Zope's stats if it is running as a separate
server and logging separately?

Yup.

ZServer runs at Port 80 and logs all of its activity to Z2.log. I have
Apache running on port 8080 and it is logging to its own access log. I run
Analog (and Webalizer) on the Z2.log (cron) and write it to the Apache HTML
directory. That way I can browse all the Zope stats I want while not having
to import the static HTML into Zope. This also works great for documentation
and other things that come as static HTML.

The site, though, is pure Zserver.

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the zope-announce mailing list and
    the Zope.org site.

    The ZWN is changing days!  The next ZWN will be published on
    Tuesday.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * ZEO will go Open Source

    ZEO, the commercial Zope scalability option from Digital
    Creations, will go Open Source. After a trial period in mid-April,
    it will be available to everyone by mid-May.

    ZEO (Zope Enterprise Option) turns Zope into a distributed
    transactional object system, allowing people to add processors,
    machines, and networks to scale their web applications.

    More information can be found on the ZEO Product page.

    http://www.zope.org/Products/ZEO/

  * Oracle 8i Setup file, by Chris Petrilli

    Chris has released his Oracle setup file.  This file is used to
    create the Oracle library.  It has been tested internally for a
    couple of weeks.  See Chris's announcement for a caveat.

    http://www.zope.org/Members/petrilli/Oracle8i

  * Zope LATEX Math, by Bruno Vernier

    On his site, Bruno describes how to use LaTeX notation to render
    mathematical expressions directly from Zope.

    http://ess.vancouver.bc.ca/zope/math

  * Users Group - Ohio

    James Orbin <jorbin33@hotmail.com> would like to set up (or would
    like to participate in) a Zope users group for Ohio.  If you are
    interested, please write James, or see:

    http://lists.zope.org/pipermail/zope-announce/2000-March/000137.html


New Products

  * Software Product: L10NFolder, by "fog"

    The author writes, "This is a subclass of the standard folder with
    some added bonuses. The L10NFolder support localized properties
    and search paths."

    http://www.zope.org/Members/fog/l10nfolder


Updates

  * Software Product: XML Document, by Amos Latteier

    XML Document has been updated to work with Zope 2.1.6.  The latest
    release is 1.0a6.

    http://www.zope.org/Products/XMLDocument

  * Software Product: Zope MySQL Database Adapter, by "mordred"

    "mordred" has released an update to the MySQL Database Adapter, by
    Michel Pelletier (Portland). This release is 1.1.4, and fixes one
    bug:

      - Fixed a bug that caused Zope to fail on selecting aggregate
      functions such as 'select max(number) from table'

  * Software Product: ZWiki, by "simon"

    ZWiki is a Wiki web for Zope.  Zope and Wiki are a good
    combination.  Wiki assumes that, in general, users are
    trustworthy.  Zope, with it's security and transaction history,
    makes it easy to trust users.

    ZWiki is a sort of anarchic collaborative authoring system.  This
    version, 0.5, streamlines the default pages and UI, and disables
    the experimental catalog support. This release is intended to be
    immediately usable out of the box.

Zope.org items

  * How-To: Changing Base Classes for a ZClass, by "AlexR"

    When you create a ZClass, you are given an opportunity to chose
    which classes it will inherit from.  Since ZClasses are often used
    for rapid prototyping, you will not always select the correct
    classes the first time.  It is quite a lot of work to create a new
    set of classes with the correct bases and to move all the contents
    into them from the old classes.  Armed with this How-To, you will
    be able to change the base classes of a ZClass in-place!

    http://www.zope.org/Members/AlexR/ChangingBaseClasses

  * How-To: Serve PHP/Perl within Zope, by "Mamey"

    "As you migrate your site to Zope, you may want to embed a
    previously created PHP or Perl directory tree within Zope. Or
    perhaps you found a nifty web application that is coded in
    PHP/Perl and want to serve it within your Zope site."  This is a
    bit more advanced than simply rewriting certain URLs to be served
    by a different server.  This How-To will actually allow you to
    embed the external content in dynamic Zope pages.

Thanks so much everyone for all the help...actually, I ended up still
being able to use Zserver (without pcgi)...I left  the cgi programs on my
separate non-Zope site...and then for the image source, I just used a link
to the site, with all the corresponding parameters to generate the
picture...like so:

<img src="http://www.mynonzopesite.com/cgiprogram?parameters">

This worked! So, I was able to keep the regular Zserver, and still do
calls (at least for an image generation) to a cgi program residing on a
completely different site...looks like I will stick with Zope now, since I
am able to do this. :-)

> What have you run into that makes you think there is a conflict?

When I would do "rpm -Uvh Zope-pcgi-2.1.4-1.i386.rpm"

I would get the following message:

"error: failed dependencies:
        Zope-zserver conflicts with Zope-pcgi-2.1.4-1
        Zope-pcgi conflicts with Zope-zserver-2.1.2-3"   

But I no longer need pcgi, so I guess this isn't a problem for me anymore.

Thanks Again,
Jessica

Nope ...

I installed Zope-2.1.4-linux2-x86 and worldpilot-release-1.0.4.tar from
the zope-topdir. It installs correctly in ~/lib/python/Products/WorldPilot,
but when restarting the server, there is no "WorldPilot" or something
similar in "Available Objects" ...

I did:

umask 000
mkdir /var/spool/worldpilot
mkdir /var/spool/worldpilot/storage
mkdir /var/spool/worldpilot/storage/user
mkdir /var/spool/worldpilot/sessions
mkdir /var/spool/worldpilot/user
chmod -R 700 /var/spool/worldpilot

I set "DOMAIN.py" to domain="math.uni-bonn.de"

I thought that i found the error - WorldPilot is the only Product
i ever tried that uses DOS-Fileformat for (some) of it's files ...
I converted those ^M (meaning 
) to UNIX-format, but it still does
not show up in the available objects	;-(

Still, those DOS-format may be part of the problem?!?!

Confused ...

User-defined role authenticationAdam,

Something before I answer your question.

Please don't send HTML formatted mail to mailing lists.

Not all members use clients capable of reading it correctly, it makes it v
difficult to decipher when using elm for example.

OK that said onto the question.

You need to create users that have that role and then set permissions
appropriately for the location in question.

For example try turning view permissions off for the location. then try
browsing to it.

I have defined a role, editor, in my Zope system. It is not clear to me how
to prompt a user who is not a manager to authenticate so that Zope will
recognize the user as something other than anonymous. Any pointers?

Please also send the traceback along with all problems you send to the

Help very desperate....


We have a Zope site running: 
	Zope version: Zope 2.0.1 (source release, python 1.5.1, linux2)
		(also happens on a seperate box running Zope 2.1.6) 
     	Python version: 1.5.2 (#6, Sep 22 1999, 10:32:58) [GCC 2.8.1] 
     	System Platform: sunos5, Ultra-2  

It seems that if a user hits a page that either does an intense database
query or iterates over a large number of items, all other users are
prevented from accessing any page....! This problem may to be related to
the dtml-in but we are not sure.

For example suppose user A hits the following page (before user B hits
his page):
<!--#var standard_html_header-->
<dtml-in "_.range(999)">
	<dtml-var "_['sequence-item']">
	<dtml-in "_.range(999)">
		<dtml-var "_['sequence-item']">
	</dtml-in>
</dtml-in>
<!--#var standard_html_footer-->

And User B tries to access this page:
<html><head>
</head>
<body>
This is test
</body>
</html>

User B is prevented from accessing his page until User A's page returns.

Please help ASAP

I'm not sure I understand this. Perhaps you could rephrase the question.

We're phasing out hosting in favor of DASH (Dedicated Application Server
Hosting). This is not a price quote: For about $200/mo, you can get a
Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT

The RaQ3 is a Intel-like setup (AMD K6-2, I think). Earlier models used an
embedded MIPS CPU. I have no personal experience with either, but we use a
fair number of them (and some older RaQ models). Zope ought to run just
fine on it, but I've never tried.

I'm doing some Zope development on a VA 500 (dual P-II-350), and we have
two of them for mailservers. No complaints. They come with Red Hat. Using
my own RPMs for now.

I will stop babbling at once! (it is just this urgency that drove me ...)

Of course, the *other* one needs to allow one to write to the own

Message-ID: <Pine.LNX.4.10.10003291624590.20418-100000@kenny.comstar.net>

Environment: Red Hat Linux/Intel, Zope 2.1.6, GenericUserFolder 1.1.0

Problem: I have a GenericUserFolder in a folder in the root folder. When I
log in to the initial Zope management screen, with a user with both
Manager and Owner roles (andy), I get this as debugging output:

2000-03-29T21:23:04 PROBLEM(100) GUF gudid is   

Even though I am not going into the folder with the GUF. Probably this is
due to just accessing contents information. Note that it says "gudid" and
not "gufid", which is what's in the code, which is a bit odd. It's also
printing some squirrely 8-bit character that doesn't paste in.

The folder with the GUF (XXX) has acquisition turned off for all
permissions, and all permissions enabled on Manager. The GUF itself has
normal security. In addtion to this, the user is assigned the local roles
of Manager and Owner in both XXX and XXX/acl_users. It doesn't seem to
matter whether these local roles are assigned or not.

If, as my user with Manager and Owner roles, I try to get into XXX, this
happens in the debug log:

------

The first three messages seem okay to me. The problem is that it is only
validating my user for the Anonymous role, and from then it seems to be
working as it should: It pops up a login document. The login stuff and
authentication seems to work properly. But it is not getting the correct
Roles from the top-level acl_users. The superuser works as you would
expect, until you look at the debugging info.

The difference here is on the first try (with andy), it crawls up twice
and fails each time, but with the superuser, it again crawls up twice
(gets just the Anonymous role at first), but on the second crawl,
validates the correct roles (note that manager appears twice).

Tracebacks dont look useful, just raising the LoginRequired exception, and
the only reason I have a traceback is because of debug mode.

Is this a bug (whose bug is it, anyway?) or a feature?

(BTW, that's a Python XXX, not a porno XXX. So don't flood the box looking
for pix of hot naked teen action. You won't even find any hot Python
action yet.)

Zope is greate, all reviews say so. Most of the reviews complain the
documentation.

I believe all come to known zope have experience the same difficults and all
those remains can feel the power of zope.

Not only the documentation is matter. Under the greate architecture, zope is
inconsistance, non-intutive, and mistiness.

To be fast to market is not enough, it must also easy to maintain, endure
greate and fast change to make zope success.

To make good use of zope, one should paid more attentation on content
instead of control. Making separation of control and content as deep as
possible. Write re-usable, structural components.

I believe the following is very important :

Message-ID: <NDBBJGKAALOFPHJIDGAIKEMDCAAA.mdlatham@mail1.scottsboro.org>

Ok, I've got the z sql method & odbc working correctly, and from a screen i
can input a date ( as text string) and product which then returns a nice
 and fast! ) graph of dates on the x axis versus avg values on the y. Now
from the documentation you can only get back 2 variables to use in the graph
but i need to plot about 5 Y values. So i thought about multiple graphs but
can't get that to work either.
    My solution was to create 5 radio buttons asking for what type of plot
they want, then based on the button selected fire off the appropriate
<action>. I'm new to Zope so i can't seem to get the Conditional statement
to work right on the <submit>. Anyone with any experience in any of this
please send suggestions. Thanks.

Hello,

I have a sprinkling of Pystones for everything from the original Qube to a
P3-700:
http://weblogs.userland.com/qube/stories/storyReader$289

If you're doing any Zope work, you might consider as a minimum a RaQ3. Even
then I would think twice. There's a massive performance boost with the
P3-600 and P3-700.

I don't have any results for a RaQ3, but based on the CPU, it's not at all
an ideal Zope environment.

If you want a fast, cheap, Zope box look at the G3-450s. Even an iMac. Or a
Celeron. But not the Cobalt lineup.

Hi All,

Ive created a Product on my site that clones a file, then changes its
properties and
places the new file into whatever folder Im accessing that Product from.
It was working fine until I moved a bunch of folders. Basically, In the root
folder I
had a folder called website, then within that, folders called topstories,
sports,
weather etc. I copied the topstories, sports, weather folders to the root
directory and
then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to
access
manage_changeProperties". I am listed as a Manager of the site though, and
seem to have
full permission to do anything. I have discussed this with the superuser and
we can't figure
out why this happening.

keeping all the power of OO and Python.

Hello:

I'm not getting dtml-let. I use it to create a variable that I can access, correct?

Say I want to initialize a counter, and change it from 0 1 each iteration of a loop.

This will print out rows of a table with alternating background colors:


<dtml-let x=0>
</dtml-let>

<dtml-in "getElementsByTagName('book')" >

<dtml-if x==0>
	<tr bgcolor="DDEEAC">
<dtml-else>
	<tr>
</dtml-if>


write out some html

</tr>

<dtml-if x==0>
	<dtml-let x=1>
	</dtml-let>
<dtml-else>
	<dtml-let x=0>
	</dtml-let>
</dtml-if>

</dtml-in>
</table>
</dtml-with>



The let and if syntax is not good, and I can't read anywhere on how you would accomplish this type of
construct.

Few.

Many.

Java is not an open platform.  Zope depends very much on the current
CPython implementation. Java has 'stability' issues, depending on what
vendor/platform/day of the week it is.  No in-house Java expertise.  Add
to this the list of debatable reasons why doing anything at all in Java
is a bad idea.  The bottom line is probably that we don't trust Java
like we trust C and Python.  If Java sticks around for as long as either
C or Python, then maybe I'll trust it a little, but never more than that
as long as it is a closed platform.

>It seems like a natural way to increase the performance of Zope while

Increase?  I think that's highly debatable.  We could put just as much
effort into increasing the performance of the CPython JVM or rewriting
components of Zope in C and probably get a much higher performance
return than depending on any one of a number of wildly different Java
implementations to give us that.

Consistent, everywhere?  This would require incredible re-writing and
probably break alot.  We'd rather come up with some newer, cleaner
interfaces and deprecate the old ones.  You're in luck, because now you
can propose new interfaces and corrections for existing ones, complete
with your prefered unified naming convention at the Interfaces Wiki:

I'm not sure what you mean by user space.  Zope is pretty well
segmented, we do need to clean up the application itself a bit.

> 3. support of unicode

Ah, as soon as python does, we do.  Also, soon there will be a Japanese
Vocabulary to support Japanese searching of text, and after that we are
going to try Chinese.  In Zope 2.2, using these examples, you can create
a Vocabulary object for the language of your preference.

This is kind of vague, nothing in ZODB is specific to the way Zope
stores its objects, currently Zope uses a FileStorage but there is
nothing preventing you from creating an XMLStorage or a
FileSystemStorage or a ReiserFSStorage or what have you.  Doing what you
want here can be done right now, it just has do _be_ done.

> 5. support cvs style versioning

Same as 4, all of the hooks and technology is there to support this, it
just needs to be done.

Can you define this better?

Well, there is some experimental stuff going on, but probably not
anything like xsl or xpointer, more like dealing with templates applied
to textual content that has structure.  Also some people are working on
introducing some more xml based tools in Zope.  Keep in mind also that
all the hooks are there, you just have to come up with an
implementation.  There is nothing in Zope that says you can't look at
the entire thing as XML or whatever, in fact, this can all hapen right
now.

This is one of the few genuine benefits, and soon it will be supported
in CPython so it's not a very pressing issue.

You can still use those components with Zope; why would you want them
all to be in the same language?  If those components have well defined
interfaces that Zope can work with why does it matter what language they
are written in?  I don't see this as a benefit.

Yes, we are working on these issues right now.

<dtml-let> tags only set that variable within the <dtml-let>context</dtml-let>
tags. 

The task you wish to do would much easily done using the variables set by
dtml-in. Eg <dtml-var sequence-index> will print out the 'count' if you like
for the list.

<dtml-if sequence-start> </dtml-if> (from memory?) will evaluate if it is
the first iteration of the loop.

<dtml-if sequence-even> and <dtml-if sequence-odd> will evaluate odd and
even iterations of the loop, which is what it apears you want todo.

Check out the zope quick reference document for documentation on
this

To concur with Michel --  JPython is a wonderful java prototyping
environment.  I know that people use it to do real work, as well...

But, I'm really not sure that it gains you much, given Java's high
footprint on anything that is non-Windows/non-Solaris.  

Also, JPython loses some of the nicer features of python (such as
multiple inheritance; at least the more recent functional versions
did, last I looked, 6 months ago).  This might be problematic,
depending on the guts of Zope.

If you really want Java, I suggest sticking with Servlets.  Or fork
the source code... 

But Digital Creations, please don't reimplement Zope in JPython...

best,
-tony

Let me warn you, you are allready thinking too procedurally.  Remeber
DTML is a _template_ language.

Let defines a new scope for variables, the scope being defined by the
let block.  Each time you use the let tag, you are creating and then
immediatly destroying the scope of your variable.  If you want to use
'x' in your DTML code, that code must be contained in the let block that
defines x.

What you are doing is easily done using the 'sequence-even' attribute.

<dtml-in "getElementsByTagName('book')" >
  <dtml-if sequence-even>
    Print stuff for even rows
  <dtml-else>
    Print stuff for odd rows.
  </dtml-if>
</dtml-in>

Message-ID: <38E2BA94.FF282F9B@suprize.com>

Hi,

    Since zope was introduced, I've created a handful of objects in
the nice application server and make great progress on several projects.
Thanks to DC and supports from people in this forum.

    Lately, these handful of objects keep growing and, from time to
time, I need to use find an object ID based on my vague memory. The
"find" tab in the zope interface grabbed my attention. But it seems
only accept full ID name to be put in the search field. Is there a way
to let "find" search by pattern or wild card characters? I've tried
*<pattern>%, %<pattern>%, or just <pattern> but with no luck. Please
advise and sorry for my bad memory for which only part of the names 
can be kept for a short while.

I need to do something like this:

<dtml-in "_['<dtml-var qry_name>']">

where qry_name contains the name of the ZSQL Method that I want to use.

However neither of the above works, the latter gives a traceback error,
which I daren't reproduce here because of it's length :)

The above is used inside a DTML Method which is called by passing parameters
to it from a DTML Document. qry_name is one of the parameters being passed.

Any help appreciated.

Starting to look like a thread problem for linux zopes ?
Anyone else ?

etcUserFolder is an older piece of unsupported software that may have
compatability problems with newer versions of Zope.  I don't know if
anyone out there maintains it actively.  Without similar reports I would
tend to believe that this is because etcUserFolder has not be changed to
reflect recent changes in the API.

You can do some string matching with the 'expr' field, this lets you
type in a python expression that is evaluated against each object, for
example "id[3:] == 'bob'" would match all objects beginning with 'bob'. 
There is no regular expression facility.

This probably won't be expanded on because to a point the find tool just
doesn't scale.  If you want advanced wildcard searching of textual
content, use a Catalog.

I think it's a thread problem but not anything linux related, or at
least I'd need to see proof of that.

I wonder if the fact that manage_changeProperties was a latecomer to
security makes it different in other ways.

Subject: [Zope] Problems using DateTime in dtml and python. Help...
Message-ID: <38E2F888.51937800@ne.mediaone.net>

I have been building an interface for call reports from a MySQL database
on linux slackware 7 using
recent source distributions of Zope ,MySql and python. Besides a messy
bout with the ZMySQLDA
source, which is now not an issue,  I've  done OK. The problems:

1:

  I can call the DateTime() function from dtml like this-
    <dtml-var "_.DateTime(a_later_time) - _.DateTime(an_earlier_time)">
and I get what I need - a duration of time- but in days.  Is there a
method to change this to
minutes and seconds or do I just do my own math ... result * 24 * 60
etc... Whenever I try to
use the  DateTime  objects, eg fmt=DayOfWeek etc, I get invalid
attribute errors.

2:

I would rather do this work in an External Method, but when I try to use
DateTime() in a method
I get a Name Error when I try to update the Eternal Method in Zope.

So I went  to the python command line.
>>> from DateTime import *
Traceback (innermost last):
 File "<stdin>", line 1, in ?
ImportError:No module named DateTime

Obviously, I have some work to do, but what ? Recompile Python or Zope ?

How do I get DateTime to be recognized as a module?
I noted that the contents of  the Setup file in
/Zope/lib/python/DateTime are commented out-
 # install DateTime.py
 # install DateTimeZone.py
I uncommented them for kicks and reinstalled Zope with the same results.

It seems to me I'm missing something OBVIOUS.
And help greatly appreciated...

A GUF object has just been instantiated. The squirrely character needs
to be unique and is used as a key in the cookie cache. Junk debug message
basically.

Its a bug. I'm putting together a patch release as we speak, and I hope
to have this fixed (next on my list). I was hoping that the 2.1.6 release 
would make all this crawling-up-the-tree business unnecessary but the 
change proposed doesn't seem to have been implemented.
(see http://lists.zope.org/pipermail/zope-dev/2000-January/002940.html )
I vaguely remember that the LoginManager for the PTK was going to make
use of this, but I havn't had time to pay attention for the last month or
so :-(

The Anonymous role being returned the first time is a recursion check
kicking in - during the authentication stage, we need to access your
methods in the GUF, which kicks in the authentication system again...

My bug.

</SELECT>

<input type="SUBMIT" name="SUBMIT" value="go">

</BODY></HTML>

It should "remember" the day selected and choose that as the default 
when making the select box. But for some reason the sentence:
<dtml-if "_['sequence-item'] == day"> SELECTED</dtml-if>

Doesn't work. I have also tried ... == _[day] ... == 'day'
...and a lot of other stuff but with no positive result.

I start the page with zope:8080/test?day=1

I have tried to logout with standard basic authentification, but I have
not seen nothing in Mailing List.
Only I have seen log out with  cookie-based authentication, but i have
to use standard authentification. I don't know how i can do it.
What can I do to logout with standard basic authentification?

Thanks

[exec. summary -- concurrent requests becoming serialised; suggestions]

Hi,

I ran your test script on our zope server, and managed to view many other
pages while zope was parsing the page...

It looks like you might not have enough available threads (or maybe database
connections?). 

It's strange that only one request at a time is processed -- are you perhaps
using Zope in single-threaded mode (using pcgi_publisher; see
doc/WEBSERVER.txt for details)? You can set the number of threads Zope uses
by changing NUMBER_OF_THREADS in Zope.cgi; the default is 4. Note that
increasing this number will also increase Zope's memory footprint, as each
thread gets its own copy of the persistent object space.

It may also be that your machine is simply choking on that test script -- it
takes a while for zope to parse and render it. Despite python switching
between threads every n bytecodes, such a script (rendering one million
items) is going to put quite a load on the machine!

On your database queries you may be using a database adaptor that doesn't
give up the global python interpreter lock during transactions. This
prevents other threads from executing. What database and database adaptor
version are you using? See http://www.zope.org/Members/petrilli/DARoadmap
for details. There is a brief description of why the interpreter lock exists
in the python FAQ, section 4.88 (http://www.python.org/doc/FAQ.html#4.88).

Although unlikely with only one user, it's also possible that you could be
running out of database connections. By default, a maximum of seven
connections can be opened to any database you add. This limit can be set by
adjusting pool_size in zope_dir/lib/pyhthon/ZODB/DB.py (later versions of
Zope allow you to tweak these things in a custom_zodb.py file; try searching
the mailing list for details). Note that increasing pool_size will again
increase Zope's memory footprint, as query results are cached on a
per-connection basis.

hth,

Hope this is not too stupid a question:

When I use the view option from within the management interface I only get
to see the 'live' (ie public) version and not the version that I'm working

Hi,

With basic authentication, the user's browser caches the username and
password, and sends them along with each request. All you can do to
invalidate the cached values is raise an "Unauthorized" exception.

<dtml-raise type="Unauthorized">
 You have been logged out. Please log in again.
</dtml-raise>

This sends an HTTP 500 Unauthorized back to your browser, which should
display the basic auth. login box again.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.12.html for
details.

Try:

_['something'] means I want the value with the literal key of 
something.

_[reftosomething] means I want the value with the key which is the 
value of reftosomething, if that makes sense.

The problem with this is that the browser will not clear its cache of this
valid username/password unless the user clicks 'OK' on the login dialog box
that pops up.  If the user clicks 'Cancel' then the browser assumes that
the user doesn't want to change the username/password, and keeps the
existing one in cache, hence, a reload of the page will be successfull.

Does anyone know of any tricks to get around this?

Hi Jonathan,

You might want to check with the ZIP - Zope Internationalisation

lately. You might find interested partners there! You can find the
ZIP-Maillist home at <http://www.eevolute.com/mailman/listinfo/zip>

Really? What would you put on the Macs? Linux, OS X or MacOS?

What makes the Celeron superior to the Cobalt-setup in your opinion?
I thought the Cobalts where rahter high-speed (full) pentiums and
that the Celeron is not well suited for server use??

In my browser (Netscape) this works if you're following a link after
aborting this process.
Another (not very nice) method is using java-script closing the windows.

Message-ID: <D1ECF6535638D3119B360004AC3D9FBC30D0FA@CORP_MAIL2>

Thanks for pointing that out. 

As I understand it, this is a limitation of the HTTP Basic Auth. spec. RFC
2617 deals with this, and says that a client may preemptively send the Auth.
header with requests without receipt of another challenge (section 2). The
browser sends this information for every request in the zope realm (if it
didn't, you'd get the login box on every page). The server also sends an
authentication required header for every page that is protected, so this
behaviour in fact is quite logical.

The only way around it is to use a different authentication mechanism, like
Generic User Folder, et al.

Oh, yeah, and I meant 401 Unauthorised... what a week...

So, ZTables is going to die silently? I don't know much about it, but
considering the number of times I use TinyTable I would say that
ZTables is a needed datastucture for handling larger amounts of data.

Of course I understand and encourageDC to sell it as a commercial
extension, but I have problems understanding why they don't release it
to
the public if they lost interest. Anyone from DC?

Hello!

My current ISP has no interest in supporting Zope and will not install some
kind of 'Long Running Process', so I can't install it myself...

Can someone recommend an ISP that supports Zope?

I found Armored Internet, but it seems like they only support Zope for
Business Services (and they also charge $37.50/month for it). So if someone
knows an another ISP, preferable cheaper, PLEASE let me know!

Hi,

I have learning Zope for 6 months and have been
following the mailling list. I come across the
following news :  

Python 3000 will not be backwards compatible. 

Question :
How will it affects Zope ?

"Python 3000 to be Complete Rewrite. Linux Today

will not be backwards compatible with Python 1.x.
Guido plans to develop 3000 in tandem with 1.7 later
this year. (1.6 is due by summer.) "'Python 3000 is a
monumental effort - all the code will be rewritten and

Sorry to be picky here but, quoting from Table 15 on page 21 of the DTML Guide:
missing - Provide a value to be used if the ariable(sic) is missing, rather than raising a KeyError.

> <dtml-if "REQUEST.has_key('HTTP_REFERER')">

This is what I ended up doing :-)

Is it just me or does it seem silly that:
<dtml-var HTTP_REFERER missing='/'>
works as expected but
<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>
doesn't, even though they're logically the same thing?

The KeyError should be caught when evaluating the expression as well as the name in dtml-var :(

I might chuck this in the collector at some stage...

That's because 'day' in the request is a string which you compare to an
integer.
Try:

<dtml-if "_['sequence-item'] == _.int(day)"> and your code should work
fine.

BTW you can shorten you <dtml-in> statement with the range tag:

<dtml-in "_.range(31)"> will give you the same output.

Zope won't run on MacOS. It would have to be either Linux or OSX or BSD.

It runs Python faster than a PIII of the same speed. I'm assuming that's
because the cache, while half the size of a standard PIII, runs at full CPU
speed. That it supports only a 66MHz bus and memory may cause it to not
perform as well under load. I don't know. I  don't have the resources to
test that sort of thing properly.

There's more to a building a server than its Pystone rating, but it's a
start when you start looking at putting together a box.

Subject: [Zope] variable SQL insert method
Message-ID: <38E3368A.98950BF0@rrsg.ee.uct.ac.za>

Hi,
I have a database with 3 tables. I would like to create a ZSQL method
for inserting data into the tables. I started by creating a separate
method for each table, but that seems a bit of a waste. Ideally I would
like to have one method, "addEntry". The template would look something
like:

<dtml-if "tname=='supplier'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar sup_name
type=string>  etc...);
<dtml-elif "tname='manufacturer'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar man_name
type=string> etc...);

</dtml-if>

The problem is that I have to specify the arguments in the argument
list, and the arguments are different for each if clause in the above
code. Is there a way around this?

thanks
Allen

if get_returner_id(xxx) returns an empty list, then it _should_ return
nothing.

as the <dtml-in will be executed 0 times.

(untested, and will need finishing off)

Put ALL the arguments in the ZQSL method's arguments section, but give them all defaults (eg put
myvar_name='' in the arguments section)

Now, to make sure the right ones have been supplied, you need to put in an extra level of dtml-if in
each branch of your current dtml-if, something like:
<dtml-if "tname=='supplier'">
 <dtml-if "_.has_key('var1') and _.has_key('var2')">
  ... your insert here...
 <else>
  ... do something to warn of the error, such as a dtml-raise
 </dtml-if>
<dtml-elif ...>
...

HTH,

Hi,
I just ./stop and ./start'ed two Zope servers that were taking up 
rather a lot of memory;

   PID USERNAME THR PRI NICE  SIZE   RES STATE   TIME    CPU COMMAND
   841 nnle      12  33    0  395M  318M sleep 177:24  0.00% python
   834 nnle       9  23    0  531M   14M sleep 101:20  0.00% python

Is there any way of telling what objects are taking up this memory - 
could it be a memory leak in Zope at all? I'm using src-2.1.3 on 
Solaris because I still use the /REQUEST hint to see what my 
variables are.

cheers,
Tone.

Now - LinuxPPC (my Mac at home that gets 900 pystones is usable for 
me to do dev work on).
Later - choose from OS-X or LinuxPPC
You can't (easily) use MacOS because Zope has some unix-centric parts 
that don't translate well to the Mac.

>What makes the Celeron superior to the Cobalt-setup in your opinion?

The Pystone scores are higher
Celeron-400a
Pystone(1.1) time for 10000 passes = 1.78
This machine benchmarks at 5588.87 pystones/second
vs
Qube2
Pystone(1.1) time for 10000 passes = 8.81
This machine benchmarks at 1135.07 pystones/second

Sorry, not qualified to answer that bit. All I do know is that we 
have a 700MHz PIII here that gets 10,500 Pystones against our 
Enterprise 450 with ... 2700. As the maintenance on the Sun kit is 
roughly the same price as the PIII, you could say I'm not overly 
impressed with the Sun...

Hello,

I've just discovered Zope, and would like to get more information about it
as it
seems quite interesting . But I'm not sure I could use it for the web
project I'm
working on.

First, I'd need to stock XML files in an object database like the one
provided with
Zope. What kind of requesting language may I use ?
XQL ? Xpath ? XML-QC ? OQL ? XOQL ?

Second question, is there a java API integrated in Zope ? If not, is it
possible to
interface Zope with others java products as Resine, servlet engines, EJB
server...?

Thanks in advance

Subject: [Zope] dtml-return'ing the result of a SQL select (does not work)
Message-ID: <38E35092.A8838265@knoll-is.de>

Hi,

I just tried to implement something as described in the How-To
	How To: Use GenericUserFolder with an SQL database
It does not work. The problem boils down to the fact that I can't
dtml-return the result of a SQL query.

I wrote the Z SQL Method 'qryTest':
	select * from mytable

This method can be executed without problems. It displays all rows in
the table.

And I wrote a DTML Method 'returnData':
	<dtml-return qryTest>

When calling the method I get
	Resource not found

Traceback (innermost last):
  File D:\Programme\uZope\lib\python\ZPublisher\Publish.py, line 214, in

I'm using Zope 2.1.4, WinNT. What's going on here? Can anybody help?!
Thank you!

Watch out, this might be confusing, since Subscribe is a permission
referencing in the other direction (eventually actually needs to be
placed somewhere seperately). You have to set that checkbox in the 
account, that is supposed to access that data in it's default view,
or in that account session you must use the "Go-control" to switch to
the shared account.

Does the method return the full text if you call it
directly?

like:

http://your.zopeserver.dk/yourZclass_instance/PrincipiaSearchSource

you should get the raw contents of the instance..

If you don't , somethings wrong with the method or its
placement..
i think product/product_entry/methods is the right place..

If you get the raw text returned, the fault is with your
Zcatalog.. Have you updated it after adding the pythonmethod
??
- Checking the status-view of your zcatalog can often help to see
if it has updated correctly..

Subject: [Zope] ZSQL arguments
Message-ID: <E12afEQ-0004UC-00@marvin.nipltd.com>

Hi,

ZSQL methods can have two types of string argument, string and 
required, where required is a non-empty string and a string is (one 
assumes) a potentially empty string.

Although does not say in the ZSQL users guide, it would be nice if 
strings were also not required to exist as arguments, which to my 
mind is the logical progression of allowing an empty string.

The reason I want to do this is that I am writing sql methods which 
build queries based on the existence of certain arguments.  
Obviously I can code the logic to test for empty strings, but it 
would be neater and simpler to be able to simply have

<dtml-if myarg>
...

The other reason this would be a neater solution is that it would 
avoid the need to set up lots of empty arguments in the dtml which 
calls the sql method.

Comments?

Cheers,
Stephen

Sorry, Tom,

I was blabbering last time about hasattr. The right solution is of course:

def recursiveMethod(self, obj, result):
     if hasattr(obj, aq_parent):
            result.append(obj.title)
            recursiveMethod(self, obj.aq_parent, result)
     return result


which you will have to call like this (assuming you external method in Zope
is called recursiveMethod):

<dtml-var "recursiveMethod(<obj>, [])">

Working with a keyword argument didn't work for me. I'm sure someone can
explain you why (but I don't have time for sorting that out right now)

I eventually found the answer by creating an external method :

def SetValue (self, dictionnary, key, value):
    """Ajoute une valeur ŕ un dictionnaire"""
    dictionnary[key] = value


Which you can call with <dtml-call SetValue (REQUEST.form, 'tata', 'titi')>. It
works !...

*Increase* performance by rewriting in Java?  You've been reading
Sun's press releases again and, worse still, actually believing them;
don't make that mistake! :) 

I can think of any number of improvements that could be made to Zope,
but a translation into another language, with no clear idea of what
actual problem would be solved by the translation, isn't one of them.

	Also, take a look at: www.step-thermodynamics.com

	Their primary business is selling specialized cooling systems
	for processors, which they bond to the processor.  As a result
	they only sell their cooling system with a processor.

	They provide a lifetime guarantee on what they sell, and they
	also guarantee that a processor will run at a specific MHz
	(which in the case of a Celeron 333a processor is 500 MHz if
	I remember correctly).  That particular configuration uses a
	100 MHz front side bus speed.

	A friend of mine has got a couple of dual processor boxes with
	Abit BP6 motherboards (socket Celeron motherboards) with two
	Celerons each running at 500 MHz.

	For any task that requires fast cache, but not a lot it, they
	are great systems.

Ok.. so I opened up a can of worms.

Thanks to everyone for setting me straight. I do think, though, that
performance and benchmarking should be an issues on the tips of DC tongues.
I have been doing a lot of benchmarking (and will publish results soon)
trying to figure just where the bottlenecks are (DTML, references, SQL,
size, caching). The good and bad news is that there seems to be no
difference in many of the different tests. I can get a MAX of 40 requests
per second, and that, is that.

The reason I asked about JPython and performance was because I get a lot of
developers telling me that Servlets are much faster. Now, that being said I
am about to set up a website with servlets and pound on it till it bleeds to
see if it is true.

One of the comparisons that would be nice on Zope.org would be the servlets
vrs Zope. (JServ, Enhydra, etc).

Thanks,
J

Hi,

I ran into trouble when trying use PIL (python imaging lib) in zope
product. 
The problem is that zope's App.ImageFile is used by PIL's internals
instead of PILs ImageFile and of course this doesn't work.

Any ideas how to fix this problem?

Im using Debian Linux 2.2 pyhton packages.

Sure. You just need to 'packagize' PIL. 

Place the PIL directory somewhere in your
Zope's python's path. Add an __init__.py
to the PIL directory.

Inside the __init__.py place the following:
# Add any additional PIL modules that you want imported.
# This is one, long import statement that my email clien will
# wrap.
import Image, ImageFile, ImageEnhance, ImageDraw,  _imaging, GifImagePlugin, 
JpegImagePlugin, PngImagePlugin, BmpImagePlugin

in Zope? I could not access the locale namespace in a dtml method.

Thank you.

I can think of one: I wrote my first program in php in some minutes, while
my first zope silliness took me days.

 - BUT -

now I'm in this mailing list so I can flood you with questions.


Please keep in mind that I'm a total newbie, at the moment I know
little more than Nicholas Petreley about Zope. I'm fluent with python
and slow but steady with html.

My first site is for an antique trader (my father): four languages,
lots of photos with descriptions, some search methods, some registered
users, a private addressbook.

There will be an "uploader" interface for my brother, a public and
a "frequent customers" interface. I don't think the Photo product
is stable enough for use, so I'll try and write something by myself.

If I use a "pure" zope provider, do I need to keep the photos on
the ZODB?

Is it possible to write to the file system via an external python
method, so that I can:

 * receive a photo with netscape
 * give it an unique filename
 * write it to the file
 * update the info (filename, descriptions) on a SQL table

 and then

 * reference (from DTML) or delete (from python) the photo by the
   filename stored on the SQL table

 ?



The trouble with Zope is not that it isn't documented, but the
documentation at first makes me fell stupid. I don't know why.

It is like loving a girl you didn't have the chance to talk to.
It makes me feel stupid.

Maybe the fact that I need a 21" to look at my source, and I have to
look at the source of the page returned by the browser to see the
stack trace with my error (when there is a stack trace), has something
to do with the stress I am having during my learning sessions.

Will zopezilla (or mozzope)? enhance my Zope Experience?



Thank you for reading this far.

Subject: [Zope] namespaces and uploading files etc
Message-ID: <38E37FB9.25E18857@rrsg.ee.uct.ac.za>

Hi,
I've written an external method that will write some data to a specified
location in the server's file system. I would like a user to be able to
upload a binary file, and for the external method to then write that
file to the local file system. I understand that when a user uploads
something using an <INPUT TYPE="file" NAME="uFile"> that the file is
encapsulated in a FileUpload object. That data would be accessible in my
external method using REQUEST.uFile.read().
However, suppose my external method is defined as :
def writeFile(self, file, rootdir, filename):
    ...write data using f.write(file.read())
    return filename

I would like the argument "file" above to be a reference to
REQUEST.uFile. Also, the "filename" that is returned would be the actual
filename used (it may have been altered due to filename clashes or
whatever).
I tried using the following dtml to call this method:
<dtml-let filename="writeFileLocally(_.None, _, _.uFile,
  '/usr/local/ZopeExternalFiles/Components', _.uFile.filename)">
<dtml-var filename>
</dtml-let>
However zope complains...
I'm obviously still fumbling with zope's namespaces.

Thanks
Allen

Comparisons of this type are always quite difficult to pull off. I know that
the applications I've created are rather Zope-specific. I designed them for
Zope and they take advantage of Zope's features. It would be really
difficult to try to do a reasonable comparison, because Zope has features
the other systems don't. Sure, I could make a servlet that acts kind of like
an app of mine, but how would I simulate retrieval of data from the ZODB and
acquisition and the like?

I'm sure that I'm paying a performance price for things like the ZODB and
acquisition... but I think that price is offset by the productivity
improvements that I get as a result.

Convert the DateTime objects to seconds before subtracting::

  <dtml-let early="_.DateTime(an_earlier_time)"
            late="_.DateTime(a_later_time)"
    <dtml-var "_.float( late ) - _.float( early )">
  </dtml-let>

You can use '_.int(..)' or '_.long(..)', to, truncating to whole seconds.

Put an __init__.py in the PIL file that says:

import Image, ImageDraw 

and have it import whatever you need from pIL.

Then you can just do 
	import PIL
in Zope.


The Poll Product has some instructions on this.

I have a zope ISP (hurrah.com) and am trying to determine how fast/reliable
they are.  Is there a way to compare Zope ISPs for speed and reliability.  I
would imagine speed is the easiest to test and reliability is subjective and
based on historical knowledge.  I am just having trouble telling if my test
version of Squishdot (and my test site in general) is really supposed to be
as slow as it is.  I am used to working with a large ISP (Verio) with no
Zope.

Any ideas on how to compare or test would be greatly appreciated.

Isn't it 32kb for Postgres?

Unfortunately, the photos are up to 350kb.

Ok, ten smaller objects could do :-)))

Subject: [Zope] Date Zone Problem
Message-ID: <20000330165619.76957.qmail@hotmail.com>

Hello,

Last March 26th Portugal changed to GMT+1.

ZopeTime() returns, for instance, "2000/03/30 16:00:00.000 GMT+0".

16 hours is correct but I think it should give a GMT+1 at the end of
the date?

I found this because I'm having this problem:

I have a object with a property date that when created first time
with the factory add method uses the manage_changeProperties with
the date value added to request with,
<dtml-var "REQUEST('date',ZopeTime())">.

The object is cataloged. Then I make a search to get the objects and
sort them by date. When I render this objects dates If I format the output 
using fmt="%C %Style" the date presented is "2000/03/30 15:00:00.000 GMT+0", 
one hour less!!

Since this is not right cause the real hour is 16 I work around the
problem and discovered that the TimeHours() function returns the correct 16 
hours. That resolved my output problem.

But then again a problem emerge. I have a form to update my objects 
properties, in this case, the date property. This form when rendered
writes a <input type=text:date name=mydate>. When submited a strange
thing happen. If I output the date of this updated object with the
fmt="%C %Style" format the hour will now be correct, i.e, 16.

I though then that the "text:date" type in the html was important for this 
happening.

But the problem now is that when sorting my objects this one will be sorted 
using 16 as the hour but other objects that I did not updated, i.e, dont 
passing them trough the "text:date" form, will be giving 15
for the sort.

Questions:

Is this a internationalization of zope related problem?
Does the GMT+0 instead of GMT+1 is a zope/python bug?
Am I missing something about the international date zone system?

Best Regards,
Julio

I have the following problem:

All this objects have the same method foo
now I want my users to check that objects where the function foo shall be

when I do a

<dtml-in ids>
 <dtml-var sequence-item>

it prints out the ids of the checked objects fine,
but when I try a

<dtml-in ids>
 <dtml-call "sequence-item.foo">
</dtml-in>

he doesn't know sequence-item anymore

any ideas?

I did a private extension to DT_Var.py which incorporates 
the modifier "german-money", which returns 
1&nbsp;234,5 for 1234.5 
Just because I needed it.

I did not mention it to the group since I want a much cleaner and more
general approach for supporting multiple languages.
I dont think we could handle this with locale, since the actual page
could be in a different language.

Nope. :(
Straight Zope with a _few_ added products

I've since moved back to 2.1.4 and it works fine there. Will be setting

Can you tell me what products? I know that if you are using 
SiteAccess and don't use the most recent release it will break
with 2.1.6 in a manner much like you describe...

Hi All,

Ive created a Product on my site that clones a file, then changes its
properties and
places the new file into whatever folder Im accessing that Product from.
It was working fine until I moved a bunch of folders. Basically, In the root
folder I
had a folder called website, then within that, folders called topstories,
sports,
weather etc. I copied the topstories, sports, weather folders to the root
directory and
then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to
access
manage_changeProperties". I am listed as a Manager of the site though, and
seem to have
full permission to do anything. I have discussed this with the superuser and
we can't figure
out why this happening.

No, Zope can't, especially Python can't, because it trys to evaluate
something like sequence - item.foo.

So try

<dtml-with sequence-item>
 <dtml-call "foo">
</dtml-with

or:

<dtml-call "_.['sequence-item'].foo">

I've had exactly the same problem. I put 2.1.6 and it breaks (user
authenication), I put back in 2.1.4 and it works fine. I'm also just
using straigt Zope. Just so you know it's not isolated.

Too much effort to fix it.  We don't have the time, we are working on
too many projects as it is, even discussing ZTables takes more time than
we have.

Releasing it to the public would still take time, someone would need to
maintain it, but to maintain it they'd first have to understand it, it's
complex; as complex as the catalog.  If we threw it out to the community
I suspect it would die there also.

Besides, TinyTables could be updated to support more efficient data
structures like the BTrees that ZTables and ZCatalog use.  ZCatalog + a
more efficient TinyTables is probably 99% of ZTables.

If one makes heavy use of TinyTables but needs more functionality (but no
RDBMS) I suggest he/she takes a look at Metakit. (www.equi4.com). This
amazing software deserves more attention than it gets and has already a
very nice interface to python. Returned rows behave more or less like
Zope Record objects. You can do sophisticated stuff like joins
selects etc but it can also be used in a manner similar to TinyTable. It
is transactional and *very* fast/efficient. Currently in not multithreaded
so one needs to serialize requests. I think the author, Jean-Claude
Wippler mentioned that he is working in a thread safe python version (the
TCL one is out).

A Zope interface would have beed nice ...

yes, only in pythonish these are called attributes.

Hm, I tested it. It works for me. Can you tell me where it doesn't work and
in what way? Does it fail. Is there a traceback? Remember it will still bail
out (with an AttributeError) if the object has no attribute title!

That is because there is no high level framework with servlets.  There
is no standard authentication framework, acquisition framework, standard
object/relational model, template language, through the web managment
system, object publishing over multiple protocols... servlets don't come
with an HTTP, FTP, PCGI and a FastCGI server.  All of this you get with
Zope out of the box.

It may very well be.  With the subsequent open sourcing of ZEO however,
you could scale your Zope application invisibly to a hundred machines,
how far can  you scale that Servlet without making any changes to it at
all (or not paying money)?  Requests per second is only one tiny factor
of scale, and when you scale beyond a handful of machines it becomes
less and less important.

That's because Zope can't write it (that's what the 'w' means).  The
user you are running Zope as (if you are root, Zope turns itself into
nobody) does not have permission to write to your var/ directory.
 
> Q1.  Why is Zope looking for Z2.pid if I installed it WITH PCGI?

The Z2.pid file contains the process id of Zope, it allways writes it
and has nothing to do with PCGI.

> Q2.  If Zope still needs Z2.pid with PCGI, how do I get the file there?

Zope will put it there if it can write to the var/ directory.

Though I haven't seen any clear statement to confirm this, I believe this
is a very large part of DC's decision to release ZEO. By enabling Zope
clusters ZEO addresses pragmatically several limitations inherent in the
curent state of Zope / Python. As a side effect, redundancy brings with it
answers to concerns regarding reliablility, of hardware, if not Zope
itself, in a mission critical setting.

While some may see throwing hardware at performance / reliability needs, as
inelegant at best, to others with hopes of rolling Zope out for the long
term, this seems like a perfectly reasonable solution. Python and Zope will
continue to improve, and all Zope users will benefit. For now, leveraging
commodity priced hardware is actually about as elegant as it gets.

So, DC has heard and answered, and Zope is the better for it!

The FileStorage format is portable across platforms.  The objects in
that filestorage are portable across Zope, _as long as_ your target Zope
has the same products installed as your source Zope.

Hm. In the example

<dtml-in list>
  <dtml-var foo>
</dtml-in>

the iteration will change the namespace to that of each sequence-item
automatically. So the foo asked for will always be the foo of the current
sequence-item. Things like
<with sequence-item> or "_['sequence-item']..." are not necessary.

If you iteration is by a number of IDs, as your question suggests, though,
the example is not enough. When you iterate over a list of IDs, the
sequence-item will be an ID (that is a string) and foo will have no meaning
(it will throw an AttributeError).
There are two way of remediating this:

preferrably use objectValues(), like so

<dtml-in objectValues>
   <dtml-var foo>
</dtml-in>

If you _have_ to use a list of ids, things get more complicated

<dtml-in Ids>
  <dtml-var "_.getitem(_['sequence-item'].foo)">
</dtml-in>

(sorry about that)

All code is untested, but it should work.

OK, this is probably a stupid question, but how do I fix it?  I tried:
changing the /Zopedir/var/ folder and file settings to user=ewalstad,
group=users and had no luck running ./start.  I also tried copying one of
the other .pid files and renaming it z2.pid; that didn't work, either.

Any advice is appreciated.

Replying only to the last sentence:  Add a DTMLMethod in the root of your Zope
(call it maybe "debug_request"), with the following body:

  <dtml-var standard_html_header>
  <dtml-var REQUEST>
  <dtml-var standard_html_footer>

This works fine on 2.1.4+ -- they only suppress the "direct traversal" of
REQUEST.

Access to a version is based on a cookie set in your browser.  So
when you go into the version object and click on work in version,
the cookie gets set.  If you then access your site from that same
browser session, you *should* see the version.  This, at least, is
how it works for me <grin>.  You should see the version on the view
tab, too, though, so I think you must have some problem with your
browser sending the cookie.

Message-ID: <613145F79272D211914B0020AFF640192E8F83@gandalf.digicool.com>

Hello everybody!

Please join me in welcoming Shane Hathaway to the Digital Creations
team!!

From Shane's man page:
"""
I come from a small but growing town called Magna, Utah. I
always considered it an underrated city in the Salt Lake
Valley.  I enjoyed my friends and neighbors there and some
of them keep in touch even now.

I have been programming since I was eight years old.  I
enjoyed the Commodore 64 so much that television I still use
is actually a Commodore monitor.  I had to learn to program
early because my parents refused to buy any software--if I
wanted software, they said, I'd have to write it myself. So
I did!

I enjoy singing.  I have sung in many choirs over the years
including the Cyprus High madrigals.  I have sung enough
solos for various functions that it's now easier for me to
sing a solo than to give a speech in public.

If you ever want to butter me up for something, give me a
genuine Brazilian feijoada.  Include every part of the pig
but avoid the hairy stuff.  Having spent two years there, I
hold Brazil close to my heart.

Not long ago I wrote Web Academics
(http://www.webacademics.com), software for delivering
courses over the web.  It was designed to handle specific
needs requested by educators as well as the needs I was
aware of as a student.  I am working on porting the
education-related components of Web Academics to Zope.

Zope and Digital Creations are very interesting to me
because the product is built on solid foundations and the
company is built on a solid philosophy.  I am excited to
begin working with the team.

Subject: [Zope] Mysterious Netscape Upload failure
Message-ID: <38E3CED8.E4A2561D@palladion.com>

After banging my head on it for a couple of days, I just resolved a really ugly
problem for any Zopista who uses Netscape:  any form which contains a file
upload button was timing out, failing to send data to Zope (e.g., I couldn't
create DTMLMethods!).

The underlying cause of this was Netscape's poor tempfile hygeine:  their file
upload control handler was creating tempfiles, which it then never bothered to
clean up.  Eventually, it exhausted the tempfile namespace, at which point it
looped pointlessly trying to create a tempfile with an unused name.

I tried several reinstalls, tweaked preferences, all to no avail.  The solution
was to scrub the temp dir of all the ns*.tmp files -- everything is hunky-dory,
now.

Looking-for-the-voodoo-doll'ly,

Tres.

Additionally, I would suggest removing the "Acquire Permissions Settings" from the 
"View" permission, and making the "View" permission only available to managers.

This is easy to do, assuming you called the DTMLMethod above "debug_request" and
created it in your Zope Site Root, then you could:

1. Navigate to http://mysite.com:8080/debug_request/manage_access
2. Scroll to the bottom of that long page.
3. Uncheck "Acquire Permissions Settings" next to the "View" Permission/
4. The "Manager" box should already be check, verify this.
5. Click the "Change" button near the bottom of the permission list.

Forgive me if I over-explain.

Subject: [Zope] Restarting Zope makes Values in python class disappear
Message-ID: <200003302208.PAA10382@ifopen.com>

I've got a simple python class that has a data member that holds a list of 
strings (among other things).  I can laod values into this list fine.  
And can query the object and the list is populated.  However, after  I 
restart Zope,  the list for the class instance is empty.  The other data 
values in my class retain their values just fine.

I've got other classes that hold similar lists for which this doesn't occur.

I'm banging my head against a wall - any ideas?

Lets see here ...

KnowledgeKit
LocalFS (installed, not currently in use)
SybaseDAv2
PSQLInput
Cookie Cutter (likewise not in use)
TinyTable (see above)
A small,simple 'nes article' product
Calendar
Standard Zope stuff

That's it.

It is it's own server, so no need for SiteAccess.

In a word, yes. :-)

Here's how I do it on my site. This line tells me when a particular object
(a file object as it turns out) was last updated:

<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=Day>,
<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=pCommon>

The output looks like (for example):
Tuesday, Mar. 7, 2000 11:35am

The extra '_' business in my dtml-var tag is necessary because my file
object has a '.' in its name. I believe that

<dtml-var "spamobject.bobobase_modification_time()" fmt=Day>

should do it if you don't have a '.'

HTH,
Tim

I think you'll find the How-To on creating a mail form very helpful. You'll

Good luck.

Thanks, this is what I was looking for. I was adding object names on the the end of it, rather than

I installed Zope 2.1.6, the product called Photo, a full version of =
Python 1.5.2, and PIL on a RedHat 5.2 system.  When I bring up Zope, the =
product Photo says it is broken (in the Product Management page in the =
Control Panel).  The traceback shows the following:

    from PIL.Image            import BICUBIC, BILINEAR, NEAREST
ImportError: No module named PIL.Image


I followed the instructions in PIL.  I created a directory called =
site_packages in /usr/lib/python1.5, copied the PIL directory to there =
(/usr/lib/python1.5/site_packages/PIL),
put a PIL.pth file in /usr/lib/python1.5/site_packages which has one =
line ("PIL")

I removed the zope/bin/python file, and changed the start file to use =
/usr/bin/python

Now if I execute python and do this....

You're probably mutating the list without informing the instance that you've
changed it.  If you do:

thing.stufflist[4] = 'newstring'

or

thing.stufflist.append('newstring')

...then 'thing' has no way of knowing that 'stufflist' has changed, unless
you replace 'stufflist':

# This can be confusing, since it doesn't look like it does anything
thing.stufflist = thing.stufflist

... or tell 'thing' explicitly:

# This is the official interface to mark an object changed
thing._p_changed = 1

Your changes will also get saved if you happened to change any other
attributes of 'thing' in the same transaction, but as you've discovered this
is unreliable at best.  Explicit is better.

Cheers,

Just on this subject :

a) You may find the Perl mandarin text-splitter at www.mandarintools.com
   very useful. I rewrote it in Python once but my Perl sucks so you may 
   wish to do this yourself. Otherwise, e-mail me for copy ... it's so 
   short I'm sure you'd rather not trust mine though.

b) What algorithm do you use in your searching of text ? Is it just a
   simple frequency tally ?

You will need to use an external python method.

I am currently writing one that will take any sql query and a file name as its parameters and put the results of the query into the
file as  comma or tab delimited records with or without the the field names in the first record.

Will post info here when I have it completed

Subject: [Zope] How do I download the results of a large Query


I would like to set up a link to some SQL query results in comma delimited
ascii that will download the data rather than display it.  I am having two
problems.  First the data is coming up in the browser and I want them to
download it without having to right click and select download.  Second,
before the SQL is completed the browser times out.

I think if I solve the first problem,  the second will be Ok,  Any ideas?

Subject: [Zope] ODBC and MS SQLServer Problems
Message-ID: <20000330163600.A3429@24.64.237.96.ab.wave.home.com>

I am trying to get Zope to play nice with MS SQL Server.  They are both installed on the same Compaq Proliant server.  I can create my database, make it accessible through ODBC and then add a ODBC Connection in Zope by picking my ODBC connection from the list.  I can then use the connection just fine for SELECTs and UPDATEs for a little while (30 mins to an hour). However, eventually I get the following error:

Error Type: sql.error
Error Value: ('S0002', 208, "[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'users'.")

where 'users' is a table name.  Up until this point, it was accessing 'users' just fine, and I can still run queries on it from the SQL Query Analyzer app so I know the table is there.  My only option at this time seems to be to delete the whole database and create it again and recreate the tables.  This isn't acceptable if this system is to actually be used.

Can anyone who has gotten SQL Server and Zope working post explicit instructions.  Or better yet, let me know what is causing the above error.

Thanks.

Not a lot if Zope continues to use Python 1.[5, 6, 7].

<opinion type="personal">

People are making a bigger deal out of this than it needs to be.
I admire Guido for taking a stance and fixing the problems he
perceives in his language;  I've had to support "backwards
compatability" issues in a commercial interpretive language
before, and "It Sucks(TM)".

Here he is being honest, stating that there will be change, but
not knowing the extent, and people are carrying on like it will
be the end of Python as we know it (or to use an Australian term,
"carrying on like pork chops").  When Python 3000 comes out, it
will not render all the Python versions before it automagically
obsolete; people will still be free to use whatever version they
most feel comfortable with (heck, I came across a site the other
day still running 1.3, and quite happy with it - it runs their
_current_ applications fine).  If there is a large enough groundswell,
there is nothing stopping other people from maintaining the "1.7"
version, but I personally can't see that happening (unless Guido
goes mad and puts braces in to denote blocks :-).

It's an Open Source language - you actually have options.

One thing that is kinda amusing (to me, at least) - the fuss I'm seeing
about this is, in a way, a testament to just _how_ _good_ a job Guido's
done as Benevolent Dictator. I've been using python since v 0.9.mumble,
and there's been _very_ _very_ few times where I've had to go back and
change working code because of a python upgrade.

And that's not just the python scripts, I'm also talking about C
extensions. 

Thinking back to a previous place of work where we had perl software of
around 10-12K lines of code, it seemed like every bloody minor rev of
perl5 would break something in it.

P3K has been talked about for a long long time as the "chance to fix
stuff" (ok, it used to be known as Python 2.0, but...).  I, for one, 
am looking forward to it. (particularly if the types/classes split 
goes away).

Here's a silly thing that's always niggled me : 

How do you get Zope to render the DTML that is 
stored in properties of a ZClass ? 

eg. Consider you have a ZClass with a string 
    property called 'my_property'

    In an instance of this ZClass, you set the 
    value of 'my_property' to "Hello <dtml-var x>"
    where x might be a string, integer, image etc

    Now, if a DTML method were to call <dtml-var my_property>,
    it would display "Hello <dtml-var x>"
    How can we get the DTML to be executed too, so that it
    displays "Hello [value of x]". Is there any easy method
    other than splitting this up into different fields ? 

Apologies if this is such a trivial thing. It's
escaped me for ages.

Heh, I just ran into this same problem a few days ago.  For some reason
PIL doesn't install a __init__.py (or at least the RPM of it didn't). 
Check /usr/lib/python1.5/site-packages/PIL for a __init__.py.  If it
isn't there, then make one with this content:

import Image, ImageFile, ImageEnhance, ImageDraw, _imaging,
GifImagePlugin, JpegImagePlugin, PngImagePlugin, BmpImagePlugin

if you are starting zope as root, the following (from the Zope root
folder) should work:

chown nobody access
chown -R nobody var

then you can start.  If you're starting zope as some other user, then
replace "nobody" with other user.  All the files in var need to be owned
by nobody or the starting user.  Copying Z2.pid won't work, because zope
sets it afresh each time it runs.

No, unfortunately, it's not possible.  You can use the Sybase database
adapter to talk to SQL Server 6.5 from Linux.  SQL Server 7 evidently
has a different wire protocol which prevents it from working against the
Sybase DA.  There is no ODBC support for Linux in Zope, and though there
have been rumblings about getting such a thing going one way or another,
nothing concrete has happened.

I have seen register*Class for various classes in ProductContext, but nothing

Not entirely true. You won't be able to use some SQL Server 7 features if
you use the Sybase adaptor, but the standard stuff should work fine.

Once freetds is thread safe, it should also be useful.

It is very possible to get ODBC connectivity using the OpenLink UDBC Multi-Tier
drivers and ZODBCDA. You will have to do some minor hacking, and if you want 
access to any fields longer than 128 bytes, some larger hacking :-)
(There is I think a major bug in SQLGetString in sql.c too that causes
Zope to crash -- I think I have fixed it... at least w.r.t. the UDBC drivers,
sz should be SDWORD [for OpenLink drivers anyway]).

The UDBC drivers are thread-safe (so they say).

I have a FreeBSD box quite happily talking to MS-SQL-7, I implemented this
for a client, so I can tell you how to do it, but, not what I did to get it to
work.The joys of contract programming.

I seem get restarts often when going into the management screen on one
of my servers.
All is dandy until I go to the management screen, then I wait a couple
seconds while it restarts.

Sounds like you are really after the LoginManager, which according to
reports is usable for non-PTK, but not for PTK.

It comes with the PTK, but is a seperate product in development.

Thanks for the answer, I'll have a look. But I would like the basic
structures to be compatible with the PTK, as I might want to employ that
later on. Any comments?

Message-ID: <00033114332105.02681@tokey.kedai.com.my>

hi all,
i'm thinking of hacking zdiscussion to use rdb as the backend instead of zodb. 
but before i start anything, i'd like input from you learned zopistas.

me:- i'm not a REAL programmer.  just a hobbyist.  some of my concerns
-will a level  2 da be sufficient for high write site?  i'm thinking of using
postgres
-if i were to retain  what zdiscssion has, willl it suffice to have just one
table?  i would like to tie this to AUTHENTICATED_USER.  so i want to use user
db as the authenticating agent.  is it advisable to just put the forum table in
the user db database?  
-how would you guys do the tree from sql?
-what other improvement can be included?  what pitfalls to avoid?
-anybody done this(zdiscussion/confera with sql backend) yet?

this is just a start.  i'm not sure whether i'll succeed.  but i'll die trying
:)

thanks.

Yes, that's because the split does something else. 
Don't know if you want to pursue this further, but if so, let's try and
track it down

How do you call it from dtml?
Have you tried it from outside the ZClass (in a test situation)?

If there is a traceback, it will show in the same way as normally, I

Is it possible to do it???

Is there any possibility to get some debbugging information to know

What about this acquire permission settings checkbox?
Is there any special behavior when I added a local role in a

Can this affect acquisition of permissions of e.g. the anonymous role?

Ah, so I understand that it's not called with arguments. So you need
another external method.
Change you external method to look like this

def recursiveMethod(obj, result):
     if hasattr(obj, 'aq_parent'):
          result.append(obj.title)
          recursiveMethod(obj.aq_parent, result)
     return result


def ParentList(self):
    obj=self
    return recursiveMethod(obj, [])

Then make you external method refer to ParentList
This works without arguments from a testfolder. It should work from a
ZClass as well, but I did not test that.

Facile !... (façon de parler...) Deux solutions ŕ deux problčmes différents :

1- Pour rediriger une page vers une autre, utiliser la syntaxe suivante :
<dtml-call "REQUEST.redirect (<url>)">
Dans ce cas, on n'a pas accčs au contenu html de la page.

2 - Pour avoir accčs au contenu HTML d'une page extérieure au site, il faut
utiliser la méthode externe suivante (trouvée dans un HowTo du site Zope, que
je sois pardonné pour l'emprunt sans mention de l'auteur....) :
import httplib

def GetURL(site, filename):
 from httplib import HTTP
 http = HTTP(site)
 http.putrequest('GET', filename)
 http.putheader('Accept', 'text/html')  # we can handle text/html
 http.putheader('Accept', 'text/plain')  # we can handle text/plain
 http.endheaders()
 httpcode, httpmsg, headers = http.getreply()  # get response headers
 if httpcode != 200:
  raise "Could not get document"  # HTTP error
 doc = http.getfile()
 data = doc.read()  # read file
 doc.close()
 return data

Ensuite, aprčs avoir inséré l'External Method dans la hierarchie de Zope, pour
récupérer le texte html d'une URL distante, utiliser la syntaxe suivante :
<dtml-let mapage="GetURL ('www.toto.com', '/index.html')">

    //    Traitements...

</dtml-let>


3- Pour accéder au contenu d'une page interne au site, utiliser une référence
du style :
<dtml-let mapage="_['page_a_traiter']">

</dtml-let>


Et voilŕ !...

This becomes very funny, it doesn't work. It still returns nothing.
Although I found a way to get this working, I would really like to know the
cause why it doesn't work. I'll try something different right away.

I'm trying to assign the string:

Some playing around reveals that it doesn't like spaces and the equals sign
(=) in the string.

Am I correct in thinking that something delimited by single quotes (eg.
'this is a string') is a string? If so why can't I (or how can I) include
spaces and the equal sign inside the string.


thanks

Hi

Try <dtml-let criteria="'1=1'">

The bit inside the double quotes is evaluated as a python expression, and
thus returns the string you want.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.10.html

Unlike other tags, the dtml-let tag is quote-sensitive, requiring that
attribute values are quoted. So in the above code, you're trying to
evaluate the expression "1=1", which isn't valid Python code (you're
trying to assign a value to a value). What you want is:

	<dtml-let criteria="'1=1'">

the roles given to the user in the sub-folder *replace* the roles
defined in higher folders, due to the way user folders work. the user in
the subfolder must have the same role as in higher folders (so he can
traverse the higher folders), plus any new roles in the subfolder.

jcNTUserFolder was developped because htrd's NT User Folder has not this
functionality, which I needed also.

Thanks.

After scouring through all the docs that I can lay my hands on I finally
found an implicit reference to the above usage of dtml-let in "HowTo:
Advanced DTML techniques".

<dtml-gripe>
One of the main stumbling blocks in getting to grips
with Zope is the incoherent documentation. The information
one needs is scattered about in countless docs so a lot of
the time will be spent searching those docs. This isn't helped
by the fact that the guides and how-to's themselves contain many
errors in the examples.
</dtml-gripe>

But many thanks to the kind people on this list who have responded swiftly
to my questions.

<dtml-let criteria=="'1=1'"> should work.

In dtml-let, you write one pair of quotes to specify that your're writing a
python expression. Inside quotes you're writing python.

Examples of valid python expressions:
   'this is a string'
   23
   methodname

You can wrap up any of the above inside a pair of double quotes and then use it
in <dtml-let>

DTML-LET sintax:<dtml-let variable="exp"> </dtml-let>

So use:
<dtml-let criteria="'1=1'">
not
<dtml-let criteria='1=1'>

Or te best way ( I've  found it yesterday) :

<dtml-let valueVar="'var has value: %s'  % (var)">


All the best!

Thanks for the tip with the Zope Quick Reference! It helps a lot.
In my specific case however, I still have a problem. It may be caused by
permission settings, but I don' really think so.

I have a folder "sample_images" in the ZClass "foo".

I in the "foo_add" method I try:

<dtml-call "manage_clone(sample_images,'my_images')">

in the "with"-section. Things like "manage_addFolder" work there.

The result is:
"The object sample_images does not support this operation. "

Suggestions?

Thanks! Joachim.

I am up to a slew of tables and building the forms to add topics. 
Take a look and let me know if this is what you were looking to build.

I will add that I too am not a "real" programmer and while I have 
been using Zope for months I am still just ramping up.

Windows 2000 professional is the equivalent of NT Workstation.
on Windows 2000 server, there is two way of managing the domain: the old
way (with pdc/bdc,etc.), and the new way, with active directory. in
native mode, pdc/bdc support is disabled and my code rely on it. you may
not be concerned by this 'problem' because nt 2000 pro (aka workstation)
can't manage a domain.

bizarre, it should work. are you sure that Benutzers can *view* sub
folders? where did you create the administrator role? in the top level
folder or in the sub folders?
by the way, where do your users authenticate from? from the nt 2k pro
box (that is, the users are created *on* this box)? from a different
domain (and the domain controller is another machine)? until I can write
a better doc, also read in the zope archives the messages from 'Ava' and
'minf7'

I'm not at the office right now, so I can't do further tests. but I
should be able to reply on monday, at least.

by the way, if you want to force all users to log in, you may consider
using zope with iis, and let iis do the authentication. this may not be
possible with nt 2k *pro* (it doesn't work with nt workstation because
IIS requires nt server).

You should try, instead :
<dtml-let criteria="'1=1'">

A string is an expression, and expressions must be enclosed in double-quotes...

If you really want all content served out of mysite, you might want to
look into the SiteAccess product.

If you want just http://localhost:8080/mysite, try BASE1.

BASEn starts from the root and adds an object (from the current
aquisition path) according to n- BASE0 = root, BASE5 = root + 5 objects. 
BASE == BASE0

URLn counts the other way, starting with the current aquisition path and
removing an object according to n- URL0 = current path, URL1 current
path - 1 object. 
URL == URL0

The Zope Quick Reference has this information.

Message-ID: <38E4A089.9533A493@rrsg.ee.uct.ac.za>

Hi,
Say I want to call a dtml method that requires some extra variable, one
way is to set that variable in the REQUEST using REQUEST.set('name',
'value'), and one is able to call the dtml method.
Somebody suggested using the DTML-let tag to do the same thing, but I
haven't been able to get it to work:

<dtml-let variable="some expresion">
 <dtml-var dtmlmethodname>
</dtml-let>

when dtmlmethodname tries to access "variable" with <dtml-var variable>,
zope complains that variable does not exist. Is there a way of using the
let tag to accomplish this, or is there a different way?
Is using the REQUEST object the normal way of "passing" variables to
other methods ?
thanks
Allen

I've a ZClass which has the properties 'Title', 'Issue', 'Comment'.
This ZClass automatically reindexes itself in catalog.

Now, when I change the contents of Issue, Comment and then search the

However, when I change the contents of the Title and I again search the

However, looking inside the catalog, the ZClass is still there!

Is this a naming conflict? Or is it something else?

How dtml be used to emulate the manage* interface to change and delete
properties and DTML documents.

The editonly properties howto involved some python code were too complex for
me.

If I just use the manage method, it will re-direct me to the manage screen
which is not good.

Subject: [Zope] Variable as record type or dictionary
Message-ID: <NBBBINPMKCEPBDEGNIEOCEBIDBAA.jcoruna@umd.es>

Hi Zopists!

I need to copy a record from into a <dtml-in> tag to use it later.

Suppose:

"Client" is a select ZSQL method (select * from Client where <dtml-sqltest
client_num type=string>).
----
<dtml-in "Client(client_num='2345')">
  copy the retrieved record in a variable
</dtml-in>
----
"OrderLine" is a insert ZSQL method:

insert into OrderLine
  (order_num,client_num,client_name,client_address,...,product_num,...)
values
  (<dtml-sqlvar order_num type=string>,
   insert the column "client_num" from the previous retrieved Client record,
   insert the column "client_name" from the previous retrieved Client
record,
   insert the column "client_address" from the previous retrieved Client
record,
   ...,
   <dtml-sqlvar product_num type=string>,
   ...)
----
Registering the order lines...
<dtml-call "OrderLine(order_num='OR4567',product_num='PENCIL-0067')">
<dtml-call "OrderLine(order_num='OR4568',product_num='PEN-BLUE-8')">
<dtml-call "OrderLine(order_num='OR4569',product_num='PENCIL-0045')">
<dtml-call "OrderLine(order_num='OR4570',product_num='PENCIL-0023')">
<dtml-call "OrderLine(order_num='OR4571',product_num='PEN-BLCK-1')">
<dtml-call "OrderLine(order_num='OR4572',product_num='PEN-031')">

----

Take in mind that I can't put the ZSQL method "Client" inside the ZSQL
method "OrderLine" because the Client method needs about 10 seconds to
execute and if every "OrderLine" method needs his time plus 10 seconds (from
the "Client" method) this can take over one minute for the above example
order. This is not viable! Awaiting 15 seconds to place the order is
acceptable but over one minute isn't.

The solution is to execute the "Client" method only one time. Any ideas how
can I copy the Client record?

Subject: [Zope] DST Zone Date, help needed!
Message-ID: <20000331145302.10067.qmail@hotmail.com>

Hello all,

I'm having a hard time with dates since portugal entered DST last March 26.

If I use:

<dtml-var "REQUEST.set('mydate','2000/03/31 15:00:00.000 GMT')">
manage_changeProperties(REQUEST)

I can get from "mydate" the utc hour (14:00) with the
fmt="a-la-C %H:%M" and the current GMT DST of Portugal(15:00) with
Zope's TimeMinutes().

If I use:

<form action="manage_changeProperties">
<input type="text:date" value="2000/03/31 15:00:00.000 GMT" name=mydate>
<input type=submit>
</form>

the fmt format and zope's zopetime() give me the same hour that
is the GMT-DST (15:00), i.e, somehow the "text:date" conversion is
ignoring the Portuguese GMT-DST and assume, in this example, 15:00 as
the UTC.

Since nobody is answering I'm going into the source to find where is this 
conversion. I'll get back with a solution... I hope :-)

Thanx,
Julio

Hi All.

I have reported this earlier, but I missed to give in the trace-back.
The Situation is the following:
I can access a certain method (render) only when using the super-user
account. I have two similiar render-methods in two very similiar ZClasses
and I have set the permissions exactly alike. Rendering the one class is
ok for non-super-users, but rendering the other one gives this:
Zope Error



Zope has encountered an error while publishing this resource.

Hi everybody,

I have having some problems with the latest versions of Zope.

I am using a straight Zope 2.1.1 (tgz) + the latest Postgresql adapter.
It worked fine and give no special problem.

I have tried to update to the version 2.1.2 (RPMs) using Apache + pcgi.
Every time I try to use the zsql methods, zoe dies.

I have tried the latest version 2.1.6 (tgz). In this case I receive
keyerror: no REQUEST object.

Any suggestion ?

Can you not achieve the same thing with a single user folder in the
root, and applying 'Local Roles' to sub-folders?

That's how I use NTUserFolder.

If you are fiddling with the setup of your pages you should do this
inside a version. So nobody sees what you are doing until you are done

Hi,

1- Is there a way to keep user quotas on Zope objects ?... I.e. restrict the
amount of place a user can waste with its objects.
I briefly looked at the list's archive but did not find the actual answer.

2- Is there a way to purge the ZODB object history (ie. not the cache but the
older versions of each object) once I have a stabe "release" of my website
?... It would take less space on disk, and I suppose rendering will be faster.


Thanks,

The short answer is yes.

But your performance varies depending on how deep you want
to get into the subject. The most simple way to run Perl
CGI is:

(1) Use a Python external method to handle all CGI request.
    Let's call it "cgi_bin".

(2) Your CGI URL requests would be something like:
    http://www.mysite.com/cgi_bin?cgi=mycgi.pl&arg1=var2&arg2=var2

(3) Inside your external method, you check the values of
    REQUEST.cgi, REQUEST.arg1, REQUEST.arg2 and use Python
    pipe commands to launch the Perl interpreters and capture
    the output. (On Windows, use functions from the win32pipe
    module in Python's Win32 extensions.)

There was some discussion on all this about a week ago. Please
read the thread "newbie CGI question":

http://www.egroups.com/group/zope/showthread.html?start=26666

If you don't like the look of the URL, you can still use
Zope's SiteAccess product to tweak and interprete a URL like
htpp://www.mysite.com/cgi-bin/mycgi.pl?arg1=var1&arg2=var2

But in order to achieve decent response time, you will have to use
Apache + mod_rewrite + mod_perl + Zope. Which is more involved.

Hi again,

after read the mail I thought it could be misunderstood.

What DateTime returns wrong is the "GMT" part of, for instance,
"2000/03/31 18:08:58.3851 GMT".

It should return, "2000/03/31 18:08:58.3851 GMT+1".

Note: the hour is correct, but the gmt part no, should be added "+1".

[cb] I guess you have the permission to view the rendered document as

 Putting a

AUTHENTICATED_USER is an object , the html source of  your rendered document
will show its id
try: "AUTHENTICATED_USER.getUserName()" (with quotes) in your dtml-var tag,
which is a string representing the name of the authenticated user (or
'anonymous').

El castellano tambien funciona aqui. ;) Podrias dar mas
detalles del mensaje de error? Asegurate de que el
duenno de las carpetas sea "nobody", para que no haya
problemas durante el proceso de makefile.

Could you provide the error message itself? Make sure that
the owner of folders are "nobody". (Usually I am lazy
and change myself to superuser, and then change everything
recursively into nobody.nobody for owner.group)

The owner:group of all folders is nobody.

The system is: 

	RedHat 6.1
	ZOPE 2.1.6
	Python 1.5 

i don't know what more tell you about the error.

We too have seen more frequent restarts centered around /manage
activity.  I have one user that I can tell when he starts working in the
morning by the first Zope restart of the day.  We have not been able to
get a consistent repeat of the behavior though.

We have three servers running with one taking most /manage activity and
that machine is the one that restarts the most.

>i don't know what more tell you about the error.

In case you have not realized, what you have provided is NOT
an error message. I don't know why you call it an error message.
That is why I asked you to provide the error message. :)
If you have an error message, please provide it. If not,
please don't call something an error message when it is NOT.

Por Dios, si no hay error, para que me asustas? :)

Please read the README.txt file and follow the steps there.

(1) First check your environmental variable is properly
    pointed. Do

    echo $SYBASE

    if it does not show the directory of installation of your
    Sybase database, you are in bad shape. You need to set this
    environment variable, preferable from the moment you reboot
    the machine, but if not, from your Zope's "start" file.

          SYBASE=/mnt/sybase1192
          export SYBASE

(2) Follow the instructions in README.txt

    cp Setup.linux Setup
    make -f Makefile.pre.in boot
    make
    cp sy_occ.so ..

Then it'll work.

(Me parece que tu problema no es Sybase adapter, tu
problema puede ser Unix/Linux. Parece que no eres
familiar con Unix/Linux.)

All,

Has anyone used Andrew Kuchling's Oedipus package (parses and displays
ODP data from dmoz.org) with Zope ?
In the Oedipus 0.0.7 distribution there is a .gz file with what looks
like a Zope product distribution.
But unpacking it in the usual place for zope products doesn't make it
visible in my Zope Products folder.
I am using Linux RH 6.1, Zope v 2.1.6, Oedipus v 0.07.
Any known problems ?  Do I need to have XMLDocument imported before
Oedipus will import ?

Help !

Hi,

How do I store an object in RAM during Zope's up-time?

I don't want to store it as a persistent object.
And I don't want it to disappear after a http transaction
(so REQUEST variable is no good.)

I would like to be able to create this object given
a particular http transaction, and afterward I may
want to modify it. This is a bit like session management
data, but it's a piece of data that is shared by all
sessions...

regards,

Hung Jung

None other than to check the Zope-ptk archives for info, I haven't used

As far as I know there is not currently any such mechanism.  I wonder
if the PTK people have thought about this?  I haven't gotten around
to signing on to the PTK list yet, but I really need to.

Go to database management on the control panel, and compress your
database.  This will delete old transactions up to whatever point
you tell it, thus shrinking the database.  It won't have any affect
on rendering speed, though; from what I understand ZODB is designed
to keep read performance high regardless of the number of transactions
recorded in the database.

I read you could define a ZClass instance's method as a field-index of a
ZCatalog; but it's not working for me.

The DTML method dept_code is simply:

  <dtml-return "_.string.split(jobcode,'-')[0]">

When I call the method directly it returns a single character, the first
character of the jobcode.

The method dept_code is defined as a field-index of the ZCatalog JobsCat.
But when I access JobsCat thus:

 <dtml-in "JobsCat(meta_type='Job Opening', sort_on='dept_code')">
   <li>
   <a href="<dtml-var "JobsCat.getpath(data_record_id_)">">
            (<dtml-var dept_code>) <dtml-var jobcode>: <dtml-var title></a>
 </dtml-in>

the items are not sorted, and dept_code is null.

Can anyone see what I'm doing wrong?

Hi Tino

A lot of my pages are served by sqlsession, and sometimes I have to do
maintenance on the sql tables, and take down the database server.

Hmm, here is what I have, in DTML Method aaabbbccc::

 <dtml-var standard_html_header>

 <p> Calling asdf with variable 'foo' = 'bar', using the let tag: </p>

 <dtml-let foo="'bar'">
   <dtml-var asdf>
 </dtml-let>

 <dtml-var standard_html_footer>

And in DTML Method asdf::

  <p> <dtml-var foo></p>

When I view aaabbbccc, I see::

 Calling asdf with variable 'foo' = 'bar', using the let tag: 

 bar

which is exactly what I expected.

Can you see any differences between your code and mine?

Subject: [Zope] REQUEST weirdness . . .
Message-ID: <38E534D6.133329E4@globalcrossing.com>

'ello.

Bear with me on this one; I'm having worlds of problems coming up
with any kind of coherent way of expressing the problem. :)

I have a form which contains the following:

<input type=text name="street.address1:record">
<input type=text name="street.address2:record">
<input type=text name="street.city:record">
<input type=text name="street.state:record">
<input type=text name="street.zip:record">

To parse this data, I would ordinarily just use a dtml-with:

<dtml-with street>
  <dtml-var address1>, etc, etc, etc
</dtml-with>

No problem.  This, however, is where things get interesting.
I'm passing the data from this form to a "confirmation"
page.  The data from the first form will be simply put into a bunch
of "hidden" fields, where the user will be prompted to REALLY do what
they were doing, or cancel back to the original form.

Now, I don't want to have to re-code the confirmation page every
time I add a new value to the main form, or remove an input for
whatever reason.  What I figured I would do is the following:

<dtml-in "REQUEST.form.keys()">
  <input type=hidden
         name="<dtml-var sequence-item>"
         value="<dtml-var "REQUEST.form[_['sequence-item']]">">
</dtml-in>

This works fine for all the values in the form which aren't using
the ":record" tag, but obviously for my address, I'll 
need to iterate through it.  ie:

<dtml-in "REQUEST.form['street'].keys()">
  <input type=hidden
         name="street.<dtml-var sequence-item>:record"
         value="<dtml-var "REQUEST.form['street'][_['sequence-item']]">">
</dtml-in>

( In the original code, "street" wasn't hardcoded, and I just wrapped
  that statement around a dtml-try, where the except clause was my
  original dtml-in. )

This code doesn't work.  Upon closer inspection, the following line
was the culprit:

  <dtml-in "REQUEST.form['street'].keys()">

Upon even closer inspection, *none* of the dictionary functions would
work.  Not even <dtml-var "REQUEST.form['street']['address1']">

Then I decided it was time to just see exactly what was in the object.
<dtml-var "REQUEST.form['street']"> yielded the following results
(I had just entered sequential numbers for all five inputs):

address1: 1, address2: 2, city: 3, state: 4, zip: 5

Here's the output of <dtml-var "REQUEST.form">:

{'street': address1: 1, address2: 2, city: 3, state: 4, zip: 5, 'submit':
'submit'}

The original <dtml-with> code still works, as does
<dtml-var "street.address1">.  I've also tried using getitem:

<dtml-var "_.getitem('street')['address1']">

I'm quite confused.  It would appear that "street" really *isn't*
a dictionary at all, yet somehow the <dtml-xxx> tags still work.  What's
going on here?  I'm quite befuddled.

Thanks a lot in advance for any help, and apologies again for the
convoluted message.

Message-ID: <Z4C$7kAIdS54EwQ+@compkarori.com>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Hi,

I previously posted that I was having problems with Zope and Interbase
losing the ODBC connection ( on Win32 ).  This would happen whenever I
entered the web management interface, and at other times when I could
not identify a cause.  I then had to shut Zope down and restart it.
Zope would not allow the ODBC connection to be made otherwise.

I was using the much older Visigenic driver because the Intersolv driver
truncated varchar fields (a known bug).

However, recently I joined the Interbase mailing list, and one of the
Interbase staffers suggested I retry the Intersolv driver and recast the
varchar field as char to work round the truncation

viz. select cast(myvarchar as char(n)) as myvarchar from foo;

I am pleased to report that this works well, and over the last few days
I have not observed a single disconnection.

Furthermore, I have noticed that the very first use of the OBDC
connection after Zope started always gave an error.  This problem has
also now disappeared.

For interest, my experimental server is using a PII 300 overclocked to
450, 128Mb ram, NT4 server, and an IDE hard drive served on an ADSL
connection.  There are about 20,000 items in the ecommerce database.  I
am also using Interbase to do Zope session management.

You can reach the server by using the url below ( a PHP script on my
static server redirects to the ADSL box).

I'll post an update if the situation changes.

In addition, Interbase Corp has expressed an interest in supporting Zope
by helping/writing native drivers for Linux and other platforms which
are supported by the new Open Source Interbase 6.0

I know that in the CVS now, record objects support the Python mapping
interface (which is what you're trying to do) but before that, and I
think this is the case for the 2.1.x branch, this wasn't supported, and
you needed to access the object by attribute only.  This makes what you
want to do in DTML pretty impossible (but not impossible from python).

I guess you can try waiting for the next main trunk release, or you can
modify your record objects to support a mapping interface just like the
CVS does.  It's a very simple class in the
lib/python/ZPublisher/HTTPRequest.py module.  This is probably the
simplest solution to your problem.

Nope.  In your case it's an object with _instance attributes_ that
contain your values.

Hi there,

For some reason Zope would suddenly hang and it's thread would consume 99.9% of CPU usage.  The first time this happened the problem magically disappeared after a complete reinstall. Here's what happened while casually throwing bannerexchange code into the default DTML document.

standard_html_footer
    </td>
   </tr>
  </table>
  <dtml-var bannerexchange>
  </body>
 </html>

bannerexchange
 <dtml-var standard_html_header>
 <h2><dtml-var title_or_id></h2>
 <p>
 <!-- bannerexchange code -->
 </p>
 <dtml-var standard_html_footer>    <---- Oops!


I'm on Zope 2.1.6, do future version prevent me from making accidental infinite loops like this?

BTW: I get exponentially more done with Zope every day.  Thanks for Zope.

References: <200002291337.AA27406@rsphy9.anu.edu.au>
Message-ID: <38BC6ED7.94F2BCBC@aHIT.de>

Hi,

I created a POIDocumentClass (ZClass based on DTML Document; meta type
PIO Document) .
Than I created an instance of this POIDocumentClass id 'MyDoc' title 'My
Document'.

Now when I try to find all POIDocumentClass instances in a Folder I do
the following:

<dtml-with aq_parent>
<!--#in "objectItems(['POI Document','DTML Document'])"-->
  <!--#if
"AUTHENTICATED_USER.has_permission('View',_.getitem('id',1))"-->
      <a href="<!--#var "absolute_url()"-->"><!--#var title--></a><BR>
   <!--#/if-->
<!--#/in-->
</dtml-with> 

I get back the right title 'My Document' but absolute_url() returns
http://myserver:8080/foo/%3cstring%3e instead of
http://myserver:8080/foo/MyDoc

When I create a DTML Document instance within the same Folder
absolute_url() works fine.
I suspect there is something wrong with my POIDocumentClass :-(
Can anybody please explain this behaviour ?

I created a ZClass based upon DTMLDocument.I wanted to have

So I decided NOT to derive my class from ObjectManager.
 
Now when I create an instance of my new class within a Folder 
the instance has no id !

I think this is not a feature ;-)

Okay.  Perhaps someone else on the list can answer this one then: I
have a standard Debian install of Zope.  ZServer works fine.  Apache
works fine.  Zope shows up fine in apache.  Except... I can't log in. 
At all.  With any username.  What do I have to do to get Apache to
recognize Zope's authentication?

Don't forget that you can also download Zope and try it out easily. I'm
running it on Win32 for some development tasks, and it did not take much
effort at all to install it and run it locally. So, if you want to continue
playing you can always do that.

In terms of popularity and being supported for a long time, I do believe
that DC has been quite successful in their consulting business, so they'll
be around. And, Zope itself is open source, so there will always be avenues
available for using it.

IMHO, you'll be quite happy wiht what you can do when you migrate those apps
to Zope. In the meantime, though, you can continue using them by setting up
Apache with rewrite rules that allow you to access those CGIs still. Without
knowing anything about your app, it's difficult to state how you would
"interface" with them. There are avenues for doing so. A pretty
straightforward one might be XML-RPC. (Your perl CGIs could access Zope data
via XML-RPC.)

I think Zope is pretty stable (and I think most regular users of it would
agree). It's not generally more likely to die than your system itself. If
you do "low-level" development on a different machine, your database should
be OK. Plus, all you need to do is back up your Data.fs file. If something
got really messed up, you just drop in the back up file.

I think the answer to "what if Zope goes down" is really the same kind of
thing as "what if the server goes down?" or "what if the drive crashes?"

If you really want, there is a Zope product that will mirror your site in
HTML (and others have used wget to mirror the site in HTML). But, I think
it's better to just maintain a solid Zope, because your site quickly goes
from being a static HTML thing to being a dynamically produced, interactive
thing which can't be reasonably represented by HTML.

People on this list have done benchmarks using ab and other tools. I think
the general consensus was that with a moderate machine and a moderately
dynamic app you can do a million hits+ per day. Through more machine at it,
or go for ZEO (which lets you mirror the object database on multiple
machines) and you can handle lots and lots of traffic.

Our site (Byproducts.com) has been running on Zope since last May. I've had
very little downtime and I don't think I would blame any of it on Zope.

Subject: [Zope] trees and namespaces newbie q
Message-ID: <38BC6375.1CF97892@open.ac.uk>

Still much to learn.

I'm trying to write code to display a tree where different
kinds of node require different display action.  Each node has a
property (possibly acquired) "kind".  For nodes which reach
the innermost <dtml-else> in the code below I want the dtml
content rendered.  How can I do this?  If i refer in
some way to PARENTS[0] then id goes up with it.

Please, please, please, what expression will work here
to get the content of "id" rendered?

Code follows
------------
<dtml-tree expr="lists" branches=objectValues sort=order>

        <dtml-if "meta_type=='Folder'">
            <dtml-var title_or_id>
        <dtml-else>
            <dtml-if "kind=='discussion'">          
                    <A HREF="<dtml-var listURL>">
                    <dtml-var title_or_id></A>
            <dtml-else>
                     
                         <dtml-var id>

        </dtml-if>
        <dtml-if listinfo>

Just to follow up to myself so you know: I have seen snippets about
RewriteRules all over the place for using Apache with Zope...

I have tried everything i've found, and nothing has worked so far. 
(The RewriteRules appear to do nothing at all...)

Lot's not there. The only ones that show are those that use Zope built-in
ZServer. If your Zope is hidden behind a different web server and that
webserver's ID string hasn't been changed to mention Zope, then your site
doesn't show. Anyway none of my sites show up on the Netcraft list.

This is from the "Other Uses" page, right?  In that example, it is an error
to access the folder, since it is only meant to act as a placeholder for a
session value.  The IndexError occurs when the code tries to access the last
element in the remaining path, but there *is* no remaining path!

Access Rules execute before any authentication takes place, so
AUTHENTICATED_USER doesn't exist yet.  This also prevents them from
accessing any other Zope objects unless you give the Rule a Proxy role.

It looks like you need GenericUserFolder or UserDB.

Subject: [Zope] unhandled connect event
Message-ID: <010401bf831d$2f850440$6e00a8c0@redindustries.com>

(short time reader, first time poster)

So I've set up my zope installation to test it out for use as the intranet
server and content management system for my company. One of the features
that I intend to use heavily is the FTP access, the main users of the system
will be designers and their clients, so I want to set up an interface that
works with existing tools <DTML-rah-rah yeah>.

However everytime I connect with ftp (used Dreamweaver's FTP client as well
as EMACS) I get an "PROBLEM(100) ZServer unhandled connect event" error from
Zope. I've just upgraded to 2.1.4 which solved the crashing problem for the
most part.

My question is what is an "unhandled connect event", can I make a connect
event be handled? Is there a howto, a document or a previous thread on this
subject?

Help, I want to be a fanatic!

Right.

Yes.  One thread will win, and one thread will loose.  The winner will
get the new id.  The looser will try again.  The looser will find out
when it tries again the the id it wants is taken, and will report that
to the user.  The user picks another id.

No, but a programatic resolution protocol is planned for future releases
of ZODB.

The chances of colision are very small unless you have an incredibly
write intensive application (which is not ideal for ZODB filestorage. 
In that case, you should store your information in a RDBMS).  This the
"optimism" in optimistic.

WU IMAP on a RH 6.x box is *bizarre*.,

Ok, I kicked this off before dinner, having added some debugging output to
imaplib.py.  When I came back, there was a TON of it dumped across the console
at which I was running Zope, but no mail.  Basically, it had walked down through
all the .gnome/* directories, sucking up bitmaps, retular files, subdirectories,
everything (ICK!).

Maybe we need to add a property to the WorldPilot object which lets you
configure the folder passed to the initial list() call (e.g., to be something
like "~/Mail").  This parameter would default to the empty string, so that the
Cyrus clients would continue to operate as before.  I'll see if I can't come up
with some kind of patch.

If you click on the "what's that site running" link, and enter yours, it

My sarcasm meter is in the shop after an accidental exposure to
comp.lang.perl.misc (ugly story, don't ask), so I'm not sure how big a brick of
salt to apply.  WU IMAP is a nice stick for clobbering those who think Zope's
documentation stinks;  there is absolutely *nothing* in the package to give the
hapluse admin any clue how to configure the damn thing.

I spent about 4 hours this weekend prowling the net looking to resolve this
issue.

Hi Tres,
This was written up last week and after a little digging on egroups (I thought I
had saved that message) I finally found it. Jo Meder provided the following
information

<quote>
Chances are, that the request to "LIST *" in directory "" that 
imaplib issues cause your imapd to begin scanning your whole home 
directory which can be a lot of data, as we all know.

I worked around this problem by creating /etc/c-client.cf with the
following contents (the first line is required by imapd, otherwise
the file is not accepted):

--------------------------------------cut here -------------------
I accept the risk for IMAP toolkit 4.1.
set black-box-directory /var/spool/imap_folderlinks/
--------------------------------------cut here -------------------

I then created /var/spool/imap_folderlinks and symlinked the
directory in which my mailbox folders reside to 
/var/spool/imap_folderlinks/jo

Repeat for all users on the system and set permissions appropriately.



        Jo.
</quote>

Also some information on this can be found in the file imaprc.txt that should
be in /usr/doc/ or where ever RH dumps it. (I'm running this on SuSE myself.) I
have tried this fix but I probably will.

Subject: [Zope] RE: Different Login Screens for Management and User?
Message-ID: <38BCA9A0.C5CEA34@cs.rutgers.edu>

I was working on the same kind of problem (see my earlier post today),
and I think
I found some solution, thanks to the many hints here and in the zope-ptk
list. It's
actually quite simple.

The trick is to play with exceptions. In your standard_html_header,
include something
like (replace 'Member' with the role you want):
<dtml-unless "AUTHENTICATED_USER.has_role('Member')">
   <dtml-raise type="Please Login!">
                <p>Please login before entering!<p>
   </dtml-raise>
</dtml-unless>

When the error is raised, the standard_error_message is called, so from
there,
you can do some more tests and go to the appropriate login page. I have
not
fully tested this yet, but I think it should work. I think if you put
type=Unauthorized in the dtml-raise tag, you should get the usual HTML
login instead of the error.

Anyone has a better (more elegant/original/creative) solution?

I get this exact same problem trying to add completely normal File Objects
to my Zope site.
I can create the object empty if I don't include an upload, but the instant 
I try and upload anything it dies with the above error.
It happens _constantly_ for me, not just time to time.

Thank you. This 'patch' did in fact work although the problem was in fact more
subtle than originally described - the 'unhandled' type error only
arose if I used joins in the select part of the statement.

Message-ID: <20000301011319.A10204@devware.com>

So, if I am grokking the whole zope thang properly here, then
theoretically, when I imbed objects within my zope documents, I
shouldn't hardcode in specific urls to them.  Instead, I should treat
them almost as if they are always in the current directory, even if
they are a couple of folders up.  This way, if I want to override some
behavior in the future, I just copy the object down into the current
folder and edit it.  I notice however, that if I do this, it plays
hell with browser caching because the browser winds up pulling things
from different places all the time even if it's actually winding up
pulling the same document down.  How do other people deal with this?

Hi Lucas,

I am the original author of zGold, and I'd like to explain where it came
from and what happened to it subsequently.

zGold was originally written as an exercise of learning and also as an
example site for a conference/exhibition here in the UK.

At creation time there was no intention of releasing it to the public at
large.  It was however made available purely as a 'teaching aid'.

Subsequently it was proved that there was a serious security hole in it that
allowed users to see the clear-text passwords/usernames of other users.

Also since this was created in my 'spare time', I have had no further time
to allocate to it and it has sort of died of neglect.

That being said, I still have the original tarball hanging around and anyone
who wants it can mail me and I'll get it sent out.

caveat:
zGold is not supported in anyway and is not 'production' ready.  Use it at
your own risk.  I will not be liable/responsible for any/all problems it may
cause.

Thanks for listening.

I want to import a static HTML web site (about 10 directories,

But I couln't find any documentation about it.

Ok, I found load_site.py
 ./load_site.py [options] url file .....    

 But:
 	Which 'url' should I pass here?
 	Does 'file' mean that I only can import one file an not a 
		whole directory tree?
 
Where can I find more information?

Thank you

Howdy all.  Please note that "More" under "Zope News" has the old style
display.

Question: do you think we should have a knob available for members that
lets them toggle the home page between old style and new style?

Message-ID: <200003011127.VAA65638@mail.theinternet.com.au>

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

Hmm .. this sounds really weird. 

In my case I observed the following.

Structure:

/
  +Intermobil
    +daten (up-/download section with form for upload, dtml-methods,
external methods etc)
       +category1
       +category2
       +... (sub- and subsubfolders for storing the files)

testfile is a Winzip/Zip file (1.129 KB), uploading it gives the error.

I created a test folder somewhere else and pasted the content of the
daten folder (without category subfolders), tried to upload my zip file
there .. and -voila- it worked.

Then I changed the upload method in my test folder by inserting a
<dtml-with "Intermobil.daten"> in order to redirect the upload into a
category subfolder of the original daten folder .. and -surprisingly for
me- the upload of the test file worked, too.

I deleted the file, went back to daten, tried again and got the same
error as before.

So here I'm really confused, cause I don't know where to look and what
exactly could have caused this problem.

Thanks for bringing up this to the list again,
Thomas

Howdy all.  Please note that "More" under "Zope News" has the old style
display.

Question: do you think we should have a knob available for members that

Message-ID: <38BD079B.3F5D35D5@imeme.net>

Zopistas,

I'm setting up zope on a linux box with support for large files.
(>2gb).  I need to make sure that the ZODB will continue to work
properly past this point.  Is the filesystem stuff the ZODB does handled
by python or ZODB?

If the answer is ZODB, where can I look for fs calls to make sure
they're 64 bit?

Thanks,

   It is an URL to a Zope folder. If, for example, you've installed Zope on
http://my.server/path/to/Zope/, and you want to upload your site into
http://my.server/path/to/Zope/virtual/site (the folder /virtual/site should
be created before using load_site.py), the URL will be just
http://my.server/path/to/Zope/virtual/site

   The file can be a file, or a directory, or a list of files and
directories...

Use the absolute_url() method on the objects. 

That way, your generated HTML will contain absolute URLs to the objects,
that are the same across different Folders in your site even when the
object is acquired from elsewhere. Overriding as you described will
still work the same, the URLs will reflect the change accordingly.

Syntax variations (as always from the top of my head, not tested, YMMV):

  <dtml-var "object.absolute_url()">
  <dtml-var object url>
  &dtml.url-object;

The last notation is especially useful in HTML tag attributes, as it
won't break WYSIWYG HTML editors:

  <a href="&dtml.url-object;">Go to object</a>

Brian,

I think it's a permissions thing with tinytable. There's a permission called
something like 'access tinytable contents' which you need to give to the
anonymous user in the squishdot folder.

Well, that's how I cracked it, anyway...

cheers,

Message-ID: <38BD1DF9.49AEA62B@wildenhain.de>

Hello there,

we got a site up and running (its actually a shop solution based on
zope).
Platform is NT, zope version is 2.1.4.

Most of the time, the site is running very fast. But some times it
hangs.
It does not use much processor-time at this moment (arount 14%) but
it does not process any requests for some seconds.
Its very annoying. Does anyone know how to avoid such behavior?

thanks. I've imported the data now. 

with
python ./load_site.py -D  -u superuser:pwd http://host:8080/ directory

There are 2 problems now:

1) HTML character references are only imported within quotes.
The line 
	<a href="#Einf&uuml;hrung">Einf&uuml;hrung</a>
is imported as
	<A href="#Einf&uuml;hrung">Einfhrung</A>

and 
Transportmittel unerl&auml;&szlig;lich.
is imported as
Transportmittel unerllich.	


2) file names are used as the DTML document Id e.g. index.html
It seems to me, that index_html is the default DTML document within a
Zope directory.
Can or should I change it to index.html? And where?


Thanks
Veikko

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

What optimization do you have NT set for?

File Serving, Network processes, or local use?

By default NT optimization is set for file serving. This means that if some one is making heavy use of the file serving cpabilities
of the machine it gives less time to network processes like zope.

   Looks like a bug in HTML parsing. There is no simple solution for this.
When I got some free time (and it shouldn't be in the nearest future) I'll
add additional processing into the parser in load_site.py.

   You don't need to. Just create DTML Methtod index_html and put
<dtml-var index.html> in it. That's all.

Message-ID: <20000301065259.C26464@triceratops.com>

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.

The how-to list is a bit daunting; also I get the feeling that
there's a level of jargon necessary just to figure out what 
documentation to read.  I don't have that, so I haven't found
what I'm looking for.

Is there anything like what I'm looking for?

But, on the other hand, there is not much file-serving at all from this
machine.
I only use it to transfer log-file or such.
All other communication is over Zope only.

It appears to me it could be some dead-lock situation inside Zope or
medusa.

Subject: [Zope] Best way to run Zope for hosting apps by multiple developers?
Message-ID: <000901bf8398$f3019ca0$24886883@uoguelph.ca>

Hi,

The University of Guelph is looking at making Zope hosting available
to our departments and organisations. Because we want to be able to
use MS Access databases, we propose to run Zope on NT (so that we can
use Z ODBC). In essence, we're looking at using Zope within an ISP
hosting model, where we will provide the infrastructure and our
clients will do their own development.

I'm trying understand how to design a Zope system to achieve two
things: 1, make it less likely that a poorly written app will
compromise the service for other developers, and 2, establish a test
environment where applications can be debugged, and then moved to a
production server.

I have two questions:

1.
I've read the FAQ for ISP's, and I've seen references in the
documentation to ways of configuring a system so that Zope so that
each client gets their own instance of Zope. This would presumably
help to insulate one Zope app from another. However, I can't find any
details about how that's done... can anyone point me to more info?

2.
Given developers with administrative control of their own folders on
two Zope servers (test and production), how can I make it possible for
them to take a test application (consisting of a set of Zope objects,
let's say within one Zope folder object), and move it to a production
Zope server. I can do this by exporting from one Zope server and
importing into another, but this involves giving the developers access
to the file system (they must place their exported object in the
"import" directory on the target Zope server), and all developers will
be dropping their objects in the same place. It's not elegant, and I
can foresee various management problems and security risks arising
from it. Are there other ways to migrate a Zope application from one
Zope server to another?

Thanks in advance for any pointers,

Nick Dobbing.

Hi:

I've been using DTML successfully to generate around 20+ reports outside
of zope itself.  The result come back from the DB as a pdf document.  The
solution has worked well.

It looks like there might possibly be a bug in the dtml totalling process,
however, when dealing with larger numbers.  The results on one report are
accurate for a 20 row table with smaller totals (say, e.g., 51518), but
the larger totals are incorrect (e.g., it reports a number say in the
300,000 range rather than 1,378,835).  The DTML for that column (the TOTAL
column) is: 

<!--#var total-TOTAL fmt="%15d"-->

Has anyone else seen this? The version of DTML I'm using is from the last
quarter or so of last year.  Any ideas?

All - Have a problem which I am certain many of you have already
encountered.

With most web servers, you can create specific web server instances that
listen to virtual network interfaces on the server (virtual IP addresses).
For example, I can have multiple httpd instances, with httpd1 listening to
192.168.1.101 and httpd2 listening to 192.168.1.102 on a box where the
physical IP address is 192.168.1.100.  This is configurable within the web
server.

I want to be able to have Zope listen to a specific network interface, i.e.
- a virtual IP address that has been created on the server.  This will allow
me to have multiple Zope sites running on the same machine.  How can this be
accomplished?  Any/all suggestions are greatly appreciated.

Thanks,
-Brian

You could run Zopes behind an Apache server and connect via ProxyPass or 
FastCGI. This would even allow virtual servers on one IP address.

I will be roasted -- I thought I'd followed these directions already, and still
had it hang.  When I went back to try again, I discovered that the symlinks were
screwy (how imapd found my home directory at all is a good question).  When I
clean them up, it works!

Hmmm, /usr/doc/imap-4.5 has only a README file, which doesn't mention the
/etc/c-client.cfg file at all (it talks about building the package, and setting
up the /etc/services and /etc/inetd.conf files to make IMAP work).  Thanks very
much for reposting those directions!

IMHO this is not necessary:

just use versions for your developpment work, then commit your version 
when it's done.

If you want to stick with Basic HTTP Authentication, the key is to persuade
Apache to pass that info through.  On my setup, this involves adding the
following to the "RewriteRule" line:

 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

Also, the "RewriteCond %{HTTP:Authorization} ^(.*)" line has to be repeated
before *each* rule to which you want it to apply.

Hi everyone,

I've grepped through the source and consulted the ZQR, but I still haven't
figured out how to use bobobase_modification_time. I've got a directory
with a file object, and I'd like index_html to display when that file
object was last modified. I've tried all manner of syntax combinations,
but I can't get it to refer to the modification time of a given object and
not just the modification time of index_html. Suggestions?

-Tim

Subject: [Zope] Dealing with Dictionaries
Message-ID: <4.2.2.20000301125741.00b6b100@saladin.aisys.com>

I have a DTML method from which I want to answer a dictionary.  It looks 
something like this:

<dtml-return "{'foo':'bar', 'biff':'boom'}">

I want to be able to use this information in two different ways.  First, I 
want to be able to get a list of keys from the dictionary.  Second, I want 
to be able to get a list of values.  I could easily do this in Python, but 
I'm sure there must be a simple way to do this in DTML.  I tried something 
like:

<dtml-return "_['dictionaryVariableName'].keys()">

but that didn't work.  I did notice that if I just used 
"_['dictionaryVariableName']" I actually got the keys.

Basically I'm trying to create a system by which a user can enter a full 
string and an abbreviation for the string.  I want to be able to produce a 
list of the full strings, and I want to be able to produce a list of the 
abbreviations.

Any help would be appreciated.

Thanks.

The ZODB uses a "pluggable" Storage-derived object to do the actual reads/writes
(this is where Ty Sarna's BSDDB Storage gets plugged in).  The "standard"
Storage is the FileStorage, defined in
$ZOPE_HOME/lib/python/ZODB/FileStorage.py.

   Frank, I agree, however I probably should have been more specific.  I
would like to be able to do this using ZServer rather than using Apache or
in my case Netscape Enterprise Server.  Do you know if ZServer supports
this?

Use the source. :)

From z2.py:

  -a ipaddress
    The IP address to listen on.  If this is an empty string
    (e.g. -a ''), then all addresses on the machine are used. The
    default is %(IP_ADDRESS)s.

so in your start script, add: -a xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is the IP address you want to hook to.

Cheers

Bill

1: What is your timezone setting. It could be that dates are displayed in a
different timezone.

2: If you do your test from a DTML Method, you'll be shown the modification
date of the container it is called on. For an explanation, see:

I think I found the problem, at least for my purposes. :)  I'm not sure
if this has already been corrected in the latest versions of DTML or not
but it might be worth a check.

DT_InSV.py line 239 was:
  s=item*item

Instead, I'm now using:
  if type(item)==type(1): s=item*long(item)
  else: s=item*item

Looks like this information is needed to calculate some of the other
statistics and when the item is a large integer it will cause an
exception.  The exception is then caught and results in that item
be omitted from some calculations, such as the total.

Hi Eric:

I'm not sure how much of what I've done would apply to your situation.
Basically, the powers that be wanted some complex reports for an Access
application hooked up to SQL Server.  Access reports were not anywhere
near flexible enough to produce the output they wanted.  Consequently,
I ended up building a reporting interface onto the rather low-level python
pdf module and then hooked it up to the DB.  That way I was able to
do most of the complex stuff in python, use DTML templates whenever
possible, and output the results in pdf.  When the user clicks on a report
in access, the application shells out without them knowing it and the
next thing they know a pdf pops out in Acrobat.

I gave some thought making it available to whoever might find it useful
but haven't had much time to make it more friendly.  In particular, I
might take the pdf wrapper, which allows for high level pdf
formatting (for switching font sizes, styles, page numbering, headings,
etc), and somehow hook it up to zope.  Sometime after I started,  someone
did come up with a pdf document hook for zope, but it didn't offer the
formatting options I needed and my reports weren't going through zope.  It
might be worth a look, however, for your purposes.

If you can get away with it, avoid PDF documents altogether and just use
DTML to web enable your reports through zope.  I ended up using pdf
because the users didn't want to web enable this stuff, wanted more
precision then browser formatting allowed, and I thought it would be kind
of neat to try....

Subject: [Zope] Advanced DTML Question
Message-ID: <4.2.2.20000301155145.00b6c400@saladin.aisys.com>

I'm trying to write a DTMLMethod which will write out a list of data items 
found from a catalog, sorted in alphabetical order.  This is 
easy.  Basically I do something like this:

<dtml-in "Catalog(meta_type='foo')" sort=someAttribute>
     <dtml-with "Catalog.getobject(data_record_id_)">
         <dtml-var objvar1><dtml-var objvar2> ...
     </dtml-with>
</dtml-in>

I've got this working, no problem.  Now, since the list of these items 
might be somewhat long, I want to build a simple index at the top of the 
page and use page anchors to get to key points on the page. Basically I'm 
going to display the alphabet and when the user clicks on a letter, the 
page should scroll somewhere in the vicinity of an item which starts with 
that letter.  To that end, what I would like to do is have some code inside 
of my dtml-in loop which gets the first letter from the current entry, 
checks to see if an anchor for that letter has been written, if not, a new 
anchor tag is inserted into the stream.  My problem is I don't really know 
how to code this up.  It seems like maybe that at least some of this should 
be done at the Python level but I'm not quite sure how to split up the 
functionality.

Has anybody done anything similar who would be willing to give me some 
advice as to the best way to go about solving this problem?

Thanks.

Quick, possibly misleading idea:  if you can give your Catalog entries a
brain class with a function "anchorGroup" which returns the first letter of
the entry, then you can use <dtml-if sequence-first-anchorGroup><a
name="&dtml-anchorGroup;"></a></dtml-if>

That should have worked.  You should be able to manipulate your dictionary
just as you would expect.  What happened when you tried it? What do you get
from <dtml-var expr="_['dictionaryVariableName']">?

"Brain Class?"  Could you explain that a bit?  It so happens that the 
objects I'm getting out of my catalog are instances of a ZClass that I 
created.  That ZClass inherits from a basically empty Python base 
class.  Is this what you mean by a "brain class"?  If so, are you saying 
that I should just define a method in my Python code which does the 
"anchorGroup" thing?

Even if this isn't what you meant, I think I like the idea that you are 
proposing.  I just need to make sure that I actually understand what you 
are suggesting.

Thanks.

Thanks for the info on your PDF implementation.

Here's my situation:
I currently have a Java applet that collects data from my users.  The applet
runs some calculations and sends the results to me via email.  I copy &
paste the data into a Win32 VC++ app I wrote that converts the data into
"Forms Data Format" (FDF) using Adobe's SDK for generating FDF files.  I am
using Adobe's fdf DLL right now, but I'm excited about the idea of moving
this to Zope - No more Applet for my clients to download!!!

I have ZERO Python experience.

I use PDF / FDF because I am filling PDF files that are created by a
governmental agency; these are 'State Standard' forms, so I want to stick
with them instead of generating dynamic forms using Zope.

Question:  Are you using a Python code supplied by adobe for generating your
FDF file?  If so, I would be VERY interested in any Python code you'd be
willing to share that ties Zope to the Adobe code.

Thanks for your response.

PS, I'm replying to you and CC'ing zope@zope.org.  Is this an acceptable way
to keep the mailing list folks in the loop?
PSS, what's your name?

Eric.

// If you can get away with it, avoid PDF documents altogether and just use

No problem. 

BTW: I just discovered this neat function called string.replace(). =)

This is almost certainly faster:

    string.replace(data, '\r\n', '\n') 

I swear, not a day goes by that I don't learn something new about Python.

Subject: [Zope] How to check memory usage in Python
Message-ID: <20000301225439.43329.qmail@hotmail.com>

Hi,

This is more a Python question. How can one
check the RAM memory usage of a Python program
from within itself? Is there such a function?
(Is it platform independent? I mean, does
such a function exist for most platforms?)

If such a function does not exist in Python,
how can one do it from Unix (or Windows) shell
calls?

thanks,

Hung Jung

Message-ID: <Pine.BSF.4.21.0003011851120.5888-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * XML.com has published another Zope article by Amos Latteier,
    titled "Advanced XML Applications in Zope"

    http://www.xml.com/pub/2000/02/23/zope/index.html


New Products

  * Software Product: PMPSurvey, by "sleeper"

    This is another survey product.  It supports single and multiple
    answer questions.  It may easily be embedded within other web
    pages, and reportedly sports a nice management interface.

    http://www.zope.org/Members/sleeper/PMPSurvey


Updates

  * Software Product: FSSession, by "gaaros"

    This product can be used to maintain arbitrary per-visitor data
    (session data) without burdening your ZODB with excessive
    transactions.  It does this by storing the sessions on your
    filesystem.

    This update, 0.2.3, uses cPickle, which makes it faster and more
    flexible.  There are additional new features.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: BannerFolder, by "lalo"

    This product randomly displays one of it's contained ads or DTML
    Methods.  There are provisions for tracking click-thrus and for
    limiting the number of times an ad will display.

    The current version is 0.4.

    http://www.zope.org/Members/lalo/BannerFolder

  * Software Product: ZRadius, by "Zen"

    This is a Radius authenticator.  It can be used on it's own, or in
    Zope as a GenericUserFolder plug-in.  This is a bug-fix release,
    bringing the version to 1.1.

    http://www.zope.org/Members/Zen/ZRadius


Zope.org items

  * Zope Documentation Plan, by Amos Latteier

    Amos Latteier is soliciting feedback on his Zope Documentation
    Plan.  It describes the initiatives to improve the documentation
    situation which are underway at DC, their goals, and the
    assumptions they are based on.  If you would like to offer
    feedback, Amos is available at <amos@digicool.com>.

    http://www.zope.org/Members/Amos/Documentation/Plan

  * Tip: Using PythonMethods on FreeBSD, by "als"

    This tip points out that a module required by PythonMethods (new)
    is not enabled by default by FreeBSD's python port.  It describes
    the solution.

    http://www.zope.org/Members/als/tips/PythonMethod_FBSD

  * All Product Releases, by Martijn Pieters

    This page is designed to be used with wget, Go!Zilla, or some
    other web-sucking tool.  It contains links to every Product
    Release on the Zope site.

    http://www.zope.org/Members/mj/AllProds

  * How-To: Wizards Made Easy, by "jspisak"

    This document explains a few techniques which make it easy to
    create simple multiple-page forms, like Windows' Wizards.

JC,

It was intended as a self registration sandbox environment for a Birds of a
feather group at a conference.

It basically allows users to self-register and then creates an area for them
to experiment with Zope.

Most people seem to be interested in the self-registration bit tho. (which
is quite strange as this is only a few lines of a python external method,
whereas most of the code is taken up with mundane stuff).

Is it at all possible to have this list set reply to?

since problems discussed and solved here are logged for others to search,
surely it would be best if, by default, replies to these messages came to the
list?  I know it's just a little thing, but it still bugs me.

I know that on other lists to which I subscribe this is done.

Anyone else have an opinion on this?

be great to have a seperate archive of ZWN as a more concise form of

    You've no doubt noticed that over the last couple of months, the
actual list content in the ZWN has dwindled to nil, excpet for
zope-announce.  :-/  I'll change that first paragraph of the ZWN next
week.

That depends on what you want the 'dynamic' content to be, and where you
want to get it from.

Perhaps the webmaster at zope.org could add a how-to search interface to
the how-to listing page? You know, one that searches only how-tos (or
how-tos and tips). Sometimes using the current search box yields lots of
not-so-useful links. :(

Don't forget that you can click on the cplum headers on the How-TO index
page to sort by that header, and a second click will reverse sort.

For example, to sort by date, click "Date".

can we really run apache without running zserver?  i've been running apache as

then maybe i'm doing something wrong.

My email window dies suddenly, before I could write what I intedned ...
looks like it sent itself waaay too early. Sorry.

Anyway, have you tried the batch processing instructions at
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.5.html
They should give you some insight as to how to get the first letter. You
may then be able to set a temp variable, called CurrentAnchor, for
example, that contains the last letter that was used to set an anchor.
Testing agaimst the CurrentAnchor, you should be able to set (if not the
same), or continue (if the same).

Unfortunately, ZCatalog apparently doesn't do reg-ex searches yet.
Otherwise, I'd say create your links a alink to a page that looked for
thins that started with that letter.

Alternatively, you could look at the howto, and give a range of letter,
say a-e, f-j, etc. and just use the batch processing capabilities in
DTML. :)


Just some ideas.

This may be well hashed for most here but I'm curious about this. I've
noticed that most true mailing lists operate like this zope list, whereas
the lists I subscribe to via services like eGroups perform more like Curtis
would like it. I'm with Curtis on this, it seems much simpler to just send
the reply to the list... if I hit "reply to all" the person I'm responding
to and the others that have particpated in the thread get at least two
copies... one direct and one via the list. I'd have thought that the
multi-copy thing would quite bothersome for most overloaded list-partakers.
Plus the fact that at least some of the time messages must unintentionally
never make it to the list. I can sure live with it the way it is... but can
you give me an idea why "the standard makers" thought the way they did/do?

Thanks

I think so.  A "brain" in obscure Zope parlance is a class used to enhance a
raw tabular record, such as a ZSQLMethod or ZCatalog returns.

Hmm.  Somehow you aren't getting a dictionary, then.  It's hard to tell from
just what you've posted where it's going astray.  Are you dtml-return-ing a
literal dict as in your initial posting?  How is dictionaryVariableName set?

You need to hack the z2.py file.  Go down near the bottom (look for the
string '# HTTP Server') and you will see that the HTTP server is fired
up on the IP_ADDRESS interface.  This variable is defined on line 252
and the default is an empty string '' which means, 'all interfaces'.

You can hack the code here to do anything you want, define a bunch of
interface variables, etc...

Yes, this needs to be done better, but short of comming up with a conf
file like apache and dealing with all that, it's probably no so
realistic.  z2.py is currently config'ed with command line options,
which gets out of control after a while.

Erm... since when is the reply to field of an e-mail header NOT standard?
Why is it a bad idea?  It means the default action of replying to a message on
this list is to contribute to the list.

I'm not saying you are wrong.  I just would prefer a clear explanation instead
of an outright "that is wrong."

Well, one aspect of it is summed up in two words:

	Mail Loops.

Mail loops involving mailing lists get real nastym real fast. While it
is true that most MTAs have capabilities to detect them, it is also true
few are very effective, and even fewer admins even try to enable them.

As far as the two copies aspect, I hit reply-to-all, and delete the
individual from the recipient list. Some mailers do it properly and have
group, and individual response options.
A third aspect is end-user filtering adn reporting. On lists where the
headers are munged, often the client reader doesn't display attributions
correct, or sort correctly.

I believe i mentioned that everything in my email was from my questionable
understanding of ZOPE.  However, since nobody else has said "erm.. no, that's
not correct" i'm led to believe my assumtptions were correct. (o8

Personally, I've only used ZOPE directly with ZServer, or via an Apache server
with proxying (i don't count my as yet abortive attemts with apache and fastCGI
:)

From a review of my original assumptions (and actually looking further) i may
have been totally incorrect, believing the Zope.cgi might be a program you
could simply drop into your CGI directory, and presto.

But from closer examination, and some testing, I don't belive this is true.

Do you have a particular one in mind?  I looked, but it's entirely possible

You still need ZServer, I think this person meant that ZServer wasn't
actually listening on any outside ports, just the local domain socket to
Apache.

FYI, Zope used to be able to run without ZServer, but it was single
threaded.  You can still do that now (I imagine) but if you want
concurency you need ZServer.

Subject: [Zope] how much resource?
Message-ID: <0003021244090L.00679@tokey.kedai.com.my>

hi all,
i'm happy to say that our site (www.emedia.com.my) has been running steadily
since feb.  and we got our first 1M hits per day yesterday, and zope didn't
screeched to a halt.

now i'm wondering how much resource <dtml-if> ..<dtml-call>, <dtml-in> affect
the sending out of data to users.  will a lot of if and ins bog down the
server?  i wanted to do two different page for the same contents i.e. pages
with tables, and without tables.  i intend to do as what zope.org does for
printable page where we set a variable in the url or maybe set a cookie.  to do
that, i need to have an if statement in all files looking for that particular
variable and render the apropriate header file.   will this affect response
time? i've looked at chameleon skin but could not grasp the way it works.

if anyone got better ideas, better solution, shoot it here.  thanks

The digest version is that adding a reply-to field clobbers legitimate 
reply-to headers, that many mail readers will have difficulty replying 
to the sender's address without resorting to cut and paste, and that
it renders the 'reply to all' function on most mailers useless. 

Further more, on 'reply-to' style lists it's quite common to see
replies to messages that were intended to be send to the sender end up 
on the list - to the annoyance of the list readers, and often the
embarrassment of the person replying.

This is the downside to CC style lists. One day it will piss me off
enough to write a patch for Mailman so that it won't send a message to 
a list member if they are already in the To: or CC: fields.

Better than the other way around. See above.

The Reply-To field is intended to be a way for you to indicate the
email address that you can be contacted with when the one your sending 
from doesn't necessarily receive email - ie, you're migrating between
accounts, or posting to a publicly accessible list from an account
that isn't receiving email from that list. Whatever. The point is that 
we want to keep people's reply-to fields where possible.

Yes.  Measureable in milliseconds.  It's really not that much to worry
about just doing one conditional evaluation.  What you really want to
avoid are long loops.

A reply-to field itself is not against standards, the requested _use_ 
of the reply-to field is. Slight difference ;)

[The applicable standard is RFC822.]
(of course, technically speaking, the modified subject line in this very
post is in violation of the standard, but since it doesn't tend to cause
nasty mail loops, it largely goes unnoticed :) )

Right. Now what happens when Joe User takes a trip, and sets his 'I am
on vacation.' autoresponder on? That response is sent to everyone. That
response generates another email to him ... continue ad nauseum. Or
consider the target email being no-longer-valid. You get a mailer-daemon
response telling everyone on the list about it; which includes the
target thus generating an error which....

Granted,  when all parts of the peices of the puzzle are coded properly,
that may be reduced in frequency and/or intensity, but unfortunately,
many, many manchines are not set up properly, and software isn't coded
correctly.

See my other response. On top of those, I would add the issues with mail
<-> news gateways and loops that can/do occur as a result of improper
header munging.

Hi John -

It does make sense from those angles. If it was just me and Curtis on the
list I guess we'd still like to have it our way <g>, but that's ok. I'm sure
what Bill said about this issue having been turned over endlessly is true,
and therefore if this sort of standard has emerged it's got to the the way
to go.

OK... here is something I was talking with my workmates about.  So, i send a
message to the list from somewhere other than my list registered account.  If i
was migrating accounts, or whatever, i would change my details with the list
server.  Mailing Lists should only be sending to registered addresses, surely?

so, the list server doesn't care where the message came from (or maybe it
does), and has a FIXED LIST (as far as it's concerned) of people to forward the
messages to.  Why does it care what is in the reply-to field?


on another point that is showing in this list... Reply-To-All buttons...

having reply-to set cirvumvents ALL the problems with duplicate messages, etc.
I have the option of a) Reply-To-All, and risk doubling to someone,
OR
hitting Reply, and getting the mailing list server to send it on to everyone
appropriate.

Be warned that this is a religious topic, and that the technical
arguments presented for both sides are (arguably) easily balanced by 
the arguments from the other side.  The following URLs contains 
reasonable arguments on both sides:

  http://www.unicom.com/pw/reply-to-harmful.html
  http://www.metasystema.org/essays/reply-to-useful.mhtml  

Note that there are also some good pro-reply-to arguments under the
first URL, despite its title.

A small note: Given a message with a CC list list _and_ a Reply-To
set, a group reply on Many (even most?) MUAs will send the reply to
the Reply-To and ignore the CC list (IIRC the RFC is ambiguous in
this matter).  In this manner if an individual is using Reply-To
correctly (to hide the fact that they can't receive mail at their
From: address), they are also cutting the other recipients out of
the loop for replies.

Dangerous.

Conversely, if a list does do reply-to munging, this doesn't happen,
but the "proper" address for the original post is usually lost.

This is off-topic however.

Martijn, it is not problem of timezone setting. If yes I had to see the

29.2. date. I think that it is a bug in bobobase_modification_time. The

A very meek greeting..


Ok... i have now seen the error of my ways.   I fully admit i was not aware
there were so many problems to what seemed like such a simple convenience.  I'm
sure i can live with trying to remember to set the To address.

Please,  _I_ require no further conviction in this matter.  The information has
been provided as i asked (thanks to all who did), and I have been made suitably
aware of why this (and many other) list avoids using the reply-to field, for
the simple matter of 'avoiding problems'.

Hey.. by the way... has anyone else noticed the prolific nature of vagueness in
RFCs?

Its the old game:

  Only what is stated is defined.  

  Some things are stated to be "implementation dependent".

  Everything else is undefined and might involve green hairy
  martians coming out of someone's nose.  Or not.  Or both.

RFCs are a little better (or worse, YMMV) than standards documents
(which aren't really written in english per se), as they often
concentrate more on "intent" than definition.

If you're running Debian/GNU Linux, you need the python-dev package,
but then why not install the zope packages?

Message-ID: <Pine.LNX.4.21.0003020306150.8576-100000@zaibach.twistedmatrix.com>

just to elaborate on a few common points that have been brought up on this
list, and covered here: 

> http://www.metasystema.org/reply-to-useful.mhtml

1) "It's against the standard":

Quoting directly from that article:

The first thing to consider is that RFC 822, the document which defines
the standards and usages for email, specifically mentions this usage in
section 4.4.3:

 A somewhat different use may be of some help to "text message
 teleconferencing" groups equipped with automatic distribution
 services:  include the address of that service in the "Reply-
 To" field of all messages submitted to the teleconference;
 then participants can "reply"  to conference submissions to
 guarantee the correct distribution of any submission of their
 own.

It's not "against" the standard.  It may be a quirk of the
standard.  Detractors, please familiarize yourselves before FUDding.

2) "It causes mail loops."

Can someone please direct me to a record of this actually happening?  
It's certainly not common, and I run all of my lists with munging on.  It
doesn't cause problems there.  Several other lists (yes, some of them are
even "real" lists) that I subscribe to use munging and have never seen a
mailloop.

3) "Autoresponders are upset by it."

If you're going to use an autoresponder, configure it responsably!  Better
yet, don't use one at all.  They are annoying.  Mail loops generated here
would happen anyway.

4) "It removes useful information."

If you're using the 'reply-to' header rather than your 'from' header to
encode the address you want responses sent to, I know this is within the
standard, but you're wasting my bandwidth and my time.  I don't need to
know both what machine you sent from and what machine you want me to reply
to.  Just put your own address in the 'from' header.  (This is what most
people do anyway.  I don't know anyone that works otherwise.)

5) "It removes freedom"

This is a crock.  Anyone with a reasonably written mailer can respond to
messages how they please: reply-to munging makes it easier to reply *only
to the list* which is almost always the required functionality.  If you
really can't live without the original reply-to header, maybe you should
consider posting a message to the list asking the person's private email
that you want to get in touch with: you should really be requesting to
take on-topic discussions off the list in the first place anyway.

Speaking of wasting my money / time, if you're going to be a detractor of
reply-to munging, PLEASE be thoughtful enough, at least, to remove the
inevitable list of 18 or 20 recipients that cruft up to threads over time.  
This 'conscientious' behavior, as described by Chip Rosenthal, has gotten
me CC:ed on some messages 2 or 3 times on unmunged mailinglists.  I find
this annoying, but less so than getting flamed for sending out 8 replies
to a single mailing-list message.  And I like to conserve bandwidth.

This is much-repeated stuff, but I hate to think that there's this image
that technically sophistocated people all hate munging and think it's
evil.  Chip's opinion is, as the author of the essay referenced above has
told me, treated as gospel, and there are definitely two views on this
topic.  I strongly adhere to one, obviously. :-)

(Please, no flames, no personal email about this.  I'm not going to be
convinced of anything, this is just a message to make sure that 'newbies'
to list administration don't think that there is one answer to this
question.  It's not really for those of you who seriously consider munging
bad, and I certainly don't hope to get the policy on this list changed by
it; that would only spark more discussion of this, and one extra email
once in a while isn't so bad compared to thousands upon thousands of
messages in this thread... ^_^)

Hi,

Can you please tell us what is the configuration of your machine.  I am
very interested.  We had our servers crawl to halt when we used Zope but
we had other things running at the same time.  So I will appretiate it if
you can give us the configuration.  Are you using a database? Is it on the
same machine or by itself, and if so what are the configuration of the
supporitng servers.

1M pages/day is a great number, I think that if a farm configuration is
used you can create an extremely dynamic and scalable site.

TIA
Adonis

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.


[RH] Um, without plugging my own document, you may want to check out my
'Changing Contexts in Zope'; reading your post it may be what you want. It
is not (meant as) a howto, but a bit more general. It should go into in the
ZBook of ZDP (watch this list for announcements about ZDP rsn). In the
meantime it is available from my member page:

In addition to the valid uses posted otherwise ...

Real life example:
 At work, I am within a corporate firewall. On my unixen, my email
address is local to the machine, ie. bill@somehostname.bigcorp.com. If
you reply to that, you will be wasting your time and badwidth, since you
_can't_ access it from outside the firewall. Thus, I (in this example)
add a reply-to that has a _useable_ email address, ie. one avaiable to
you, form outside the firewall. I personally know of several hundred
people who do this, and several thousand who _should_ be. And before you
say it, no, not every mailer lets you set the 'from' header.


The point? Now you know someone who uses it. ;^)

How can this be on topic, you ask? Read on. :)

I've notice a certain increase in the amount of 'sending mass email with
zope' messages lately, and not many solutions.

Since I don't zope on windows, one method I have used when wanting to
avoid the sendmail tag (I _was_ having problems with the friggin thing
not working), was to shell out and call mail (or mailx, depending on
your *nix) to send each message. Problem was, when doing that, the
'from' address was 'nobody@foo.bar.com'. Since I wanted replies, I had
to add the reply-to to get a response that was useful.

(Hey, I din't say it was a strong effort to bring it back on topic for
the list :)
Perhaps those wanting to send out mass emails *cough*spam*cough* with
zope, and not finding answers from within Zope and the sendlmail tag
(yeah, I still look at that puppy with suspicion and a sneer :) may see
this as an option

hi, we have a PIII 500 M, dual processor running rh6.1 with 712M RAM.  there's
only zope there, and mysql to cater for banner ads.  i'm using phpAds for now
until we got a commercial ad server or until there exist a mature banner ad
products for zope. (i'mm eyeing banner ad with interest tho..)  everything is
in one server, although we're looking at adding another server for redundency. 
don't know yet how to go about this.  anybody got any pointers?  maybe
failoverd? (http://ps-ax.com/failoverd/ ) or eddie?(www.eddieware.org)

the 1M number is hits, not pages.  we have max 600k pages/day last  feb.  this
is our second month so, hopefully zope lives up to its standard.. or i'll need
to find another job *grin*

I only noticed it today (2000/03/02): the undo logs show
2000/03/01, and so do ZWiki times. This appears to be a bug in
bobobase_modification_time.

<dtml-var "_.DateTime()"> does show the right time, and the 'Content
changed' notification Zope gives does too. The bug happens on both
Windows NT and Linux.

Martijn

Thankyou.
However,to help my understanding how does this work?

Hope you don't mind - I've mailed my other, unanswered
tree question to you because I desparately need an answer.

Subject: [Zope] why doesn't this work with tree tag
Message-ID: <38BE5FB6.9EFCCE4C@open.ac.uk>

In the depths of a tree tag I want to pick up a
property of the "current" object without acquisition
if the property isn't present.

This code seems to work when used not in a tree tag
but when its in a tree tag it still finds the property
from higher up in the acquisition space.

<dtml-with this only>

What gives? How can I do this?

The version below doesn't fall over if the property
isn't present on that object, it just finds it by acq.

To fully round out this little performance study (small study of 
course) could you tell us what capacity the machine is at as far as 
you know, what Zope version you are running and with what 
configuration (Zserver alone, w/ Apache etc)?

These kinds of things are really helpful in determining Zope's 
ability to scale and in winning out the hearts of iCEO's.

Martijn, it is not problem of timezone setting. If yes I had to see the
difference in past also. And it was OK. The problem started with
29.2. date. I think that it is a bug in bobobase_modification_time. The
system time is OK, only problems with bobobase_modification_time.

The best test is creating a DTML _Document_ (not a Method!), with the
contents:

  Modified: <dtml-var bobobase_modification_time><BR>
  Current time: <dtml-var ZopeTime><BR>

Subject: [Zope] Problems installing Zope
Message-ID: <38BE54C2.B71E007E@rdel.co.uk>

Having just successfully installed and setup Zope and Squishdot
on an 486 Linux box (Debian packages made it dead easy), I
thought I'd move over to a SUN box as it is quicker and I want to
run a discussion group for the intranet here.

[SunOS 5.5.1 Generic sun4m sparc SUNW,SPARCstation-10]

After installing the latest python (and then re-compiling with
threads, doh) I unpacked Zope-2.1.4-src and ran wo_pcgi.py.
Everything seemed to go fine, so I simply fired it up using
./start. After a couple of seconds Zope (okay, Python) falls over
reporting that the ExtensionClass module couldn't be found at the
import in ZODB/__init__.py.

Actually, after investigation, none of the modules would load
from an import even though they all have .so files present in the
lib/python dir. Now, I don't know a thing about Python so I don't
know where to look to sort this out... Any ideas?

Is it something to do with shared libraries being handled wrongly
on SunOS 5?

Only other thing I can think of is search paths. I install
outside of /usr, but I can't imagine that would be a problem. Do
I need to set a PYTHONPATH or something?

Help...

I've put this into the collector, the bug is a bit weird for those, who
use bobobase_modification_time quite heavy, like me :)

aah .. the 'content changed' is a bit irritating, but it's only the
notice 'content changed' and a <dtml-var DateTime> in the next line.

Thanks,

Okay, my code was unclear in the example (though with a new created
method the modification time of the container should have changed too:),
but I'm quite sure, it's a bug.

Or, as someone else pointed out, you could use the -a parameter to z2.py.

Just run z2.py --usage for all command line options.

Uuuhhhmmm.. <g>

I just tested this myself. Here's my output:

   Modified: 2000/03/01 13:06:16.05 GMT+1
   Current time: 2000/03/02 13:06:17.86 GMT+1

Heh. One day off. And so is the Undo log.

My apologies for my unduly applied sceptisism. I'll go and hide now, and
investigate.

   I have Zope installed and running on Sun Sparc Solaris 2.5.1. Zope is in
/usr/local/Zope. There are 17 .so libraries in lib/python. Zope is running
fine: http://sun.med.ru/~zphd/
   The only thing - I am running under Apache with PCGI, no ZServer.
Nothing special for dynamic linking...

Or use CVS load_site which has a -I feature that for every index.html
creates an appropriate index_html.

Apologies for the late reply - flu :(

Yes. I create a DBH in an EM and fire away. All I get from the Zope 
system is a request of the form http://supercascade?root_id=240551 
and I start to do my queries. They are nested in the EM to 9 levels 
deep (but normally the first 4 levels are enough to get all the nodes 
of the tree with the relevant root_id). Getting the list of nodes is 
quite fast, about 0.8 seconds. Then I have to render them. I've got 
that down by a factor of ten (since this thread has started in actual 
fact!)

I've also found out just how fast a cached ZSQL method can be - one 
DMTL method that used query took 3.2 seconds on the first render, and 
0.06 seconds on subsequent renders. Obviously some more work needs to 
be done in this area and I'm looking into that.

I'm also told that our MySQL server itself does some caching ... 
looking into that.

Ah, I hadn't thought of that...my query isn't recursive however.

MySQL (MySQLmodule-1.4), DocumentTemplate and from 
Acquisition,Implicit in the main.

Dunno if this is related or not, but I got some really weird errors yesterday
when trying to view some images I had created in Zope on the 29th.

All I was trying to do was view them using the image's view tab and I got a Zope
error. Something about an invalid datetime stamp I think but try simulating it
yourself if you want the exact answer...
They also appeared as broken images when I included them on pages using
<dtml-var image>

so, Zope doesn't like leap years? ;-)

A little while back I uploaded a patch to the ODBC Database Adaptor

Indeed it did, but unfortunately it broke a host of other things.

Anyone who downloaded the patch the first time around may be

Does anyone know the inner working well enough to tell me whether or 
not Zope actually makes two separate calls to the database or whether 
it makes one caches it and uses the results twice?

If you know and would like to expand on how Zope deals with caching 
SQL data that would be great I am trying to optimize my Zope 
installation and don't want to tax the database.

Hi,

Can anyone tell me what are the predefined error types
for the <dtml-raise type=...> tag, and how to use them?
The DTML manual talks about "Unauthorized", and
"Redirect", but doesn't give any details. I haven't found
how to use "Redirect" so far.

Thanks,

Stefan.

Dunno about raise, but if you want to do a redirect, try (untested,YMMV,etc)

<dtml-call "RESPONSE.redirect(url)">

Function TimeStamp_yad(int y) in
zope-2.1.4-src\lib\python\zodb\TimeStamp.c
expects a 1900 based year (i.e. 0 = 1900, 2000=100, etc.), 
for positive agruments, when computing (y+300)/400.

TimeStamp_abst(int y, int mo, int d, int m, int s)
seems to expect a 0 based year, on the other hand.

Phil,
    nope.  Doesn't find the property called rubbish.

Baffled.
Perhaps its an architecure-related bug -

Here's what I've got.  First, I have a DTMLMethod named creditCardsAccepted 
which is defined as follows:

<dtml-return "
{
'Visa':'V',
'Mastercard':'MC',
'American Express':'AE',
'Diners Club':'DC',
'Discover':'DS',
'Carte Blanche:'CB',
'Japanese Credit Bureau':'JCB',
'Transmedia':'T'
}">

I then have a method called creditCardSelections which is defined as follows:

<dtml-return "creditCardsAccepted.keys()">

(I also tried <dtml-return "_['creditCardsAccepted'].keys()">)

When I try to "view" my creditCardSelections, I get the attribute error on 
'keys'.

Just tried that, same results (keys error).

(BTW, there was a typo in my message describing the dictionary I was 
returning.  The typo existed only in the e-mail, not in the actual code)

Hi!

Can anybody tell me anything about subclassing a UserObject?
I have had some neat errors (including seg-faults and indefinite loops by just subclassing a ZClass from User Object)
When I tried to insantiate a Subclass of UserObject Zope quit.
(I did not change anything to the default constructors and expected something like "missing argument", but not an indefinite loop :)

I am using Zope 2.1.4 on Linux/x86 (2.2.13)

Thanks.

Followup,

I just realized that I had two definitions of "creditCardsAccepted".  One 
was defined inside my ZClass, and one was defined in the folder containing 
the ZClass.  The one in the container was just answering a list.  When I 
changed that one to answer a dictionary things worked.  I then simply 
deleted the DTMLMethod in the containing folder and now I get a name 
error.  Now I'm really confused.  After deleting the higher level method, I 
now have the creditCardsAccepted and the creditCardSelections both in the 
same folder.  It seems, however, that the creditCardSelections cannot see 
the sibling method.

I'm clearly overlooking something.

Andy,

Do all of the objects have a property 'rubbish'?

Try something like:

<dtml-with aq_explicit only>
  <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
</dtml-with>

This should check that the rubbish property exists and change what gets
rendered depending on that.

J,

In the advanced tab on the edit page of a SQL Method there is a entry box
for caching information.

You could start by looking there.

Phil,

> Do all of the objects have a property 'rubbish'?

No, only some of them.  The problem goes away if
I make sure that every object has some value for
this property but that's not a good solution.  The
code you suggest (the dtml-if ...) is exactly what I intended
but on my system (Linux slackware 7 + zope  2.1.4) it finds
higher level rubbish properties.  Actually its not really
called rubbish, that's just what I was using to check
it worked before using it.

It simply doesn't work - if it works for you lets find
out what's different.  Are you on a windows platform?
What Zope version?

Just to restate the problem for new readers:-

The problem is to use "dtml-with X only" inside a tree rendering
so as to be able to test whether the current object
has some specific property.  The code works outside trees but
used in a tree it still seems to find properties by
acquisition.

> 
> <dtml-with aq_explicit only>
>   <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
> </dtml-with>


This code finds "rubbish" at higher acquisition levels.  I know it
shouldn't but it does.  Anyone throw any light on it?

Andy,

Hmm, I'm confused.

I use this 'trick' all the time, here's a bit of code from a method of mine:

<dtml-with aq_explicit only>
    <dtml-if url>
      <a href="<dtml-var url>" title="<dtml-if status><dtml-var
status></dtml-if>" target=main><dtml-var ident></a>
    <dtml-else>
      <dtml-var ident>
    </dtml-if>
</dtml-with>

Which works beautifully.

Hmmm

confusion reigns!??!

Phil

Subject: [Zope] urgent! help! strange blockings
Message-ID: <38BE960E.32E0F12E@wildenhain.de>

Hello,

I cannot get ride of those strange blockings of zope.
This happens from time to time and leads some times to
minutes without action from Zope.
I increased threads pool and decreased it, I use a much
bigger object cache (memory is not an issue on the machine)
and I pured the database (with help of an extra machine)
Zope stucks with about 18% processor use and does almost
nothing at the moment.

Any posibility for an dead-lock?

Help is very appreciated!

Configuration: Zope 2.1.4, ZODBC, Database-Size: 66MB (after purify)
Some sessions with unsafed work, 50 threads for pool, NT 4.0 (ok, this
sux, 
but we have to use ODBC with strange Databases)

I posted a message about this this morning. In effect, yes you can 
use caching and it is veery fast (one second and subsequent renders). 
For your document, I think you'll find it will speed up by a factor 
of how many times the ZSQL method is called...
tone.
ps it's the 'Advanced' tag. Put something in the 'cache results for n 
seconds' box

I've tried to do something like you suggested, but it doesn't seem to 
work.  I'm probably not doing things quite correctly.  I've added a 
"getAnchorCharacter" method to my ZClass which correctly answers the 
character I want to use as an anchor.  I've tested this and know that it 
works.  I tried using "<dtml-if sequence-first-getAnchorCharacter> ...", 
but got no result.  Could you explain a bit more about how something like 
"sequence-first-xxx" works?  I haven't found any information on this form 
of a dtml-in variable.  Perhaps I'm just misunderstanding your solution.

In thinking about this solution, it seems that if I'm inside of a dtml-in 
iterating over entries in a Catalog, the objects known to the "dtml-in" 
aren't instances of my ZClass, but instances of some catalogging wrapper 
for my ZClass.  Therefore, it would seem that my getAnchorCharacter method 
wouldn't be accessible from within the dtml-in, but only from within a 
dtml-with which sets the object to be the object referenced by the catalog 
entry.

Can you clarify all this?

Thanks.

No light, no solution, only a bad workaround:

<dtml-let temp_rubbish=rubbish>
  <dtml-tree ...> # your tree code
  ...
    <dtml-if "rubbish <> temp_rubbish">
      <dtml-var rubbish>
    </dtml-if>
 ...
 </dtml-tree>
</dtml-let>

Check the Grouping Variables subsection of
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.html

I did give you the wrong syntax; it's <dtml-if first-getAnchorCharacter>,
with no "sequence-".

I misunderstood you.  The catalog wrapper is the "brain" which needs to have
the getAnchorCharacter method.  But... Suppose you add getAnchorCharacter as
a catalogued meta_type in your Catalog?  I think that would work.

Subject: [Zope] ZOPE!  I HATE YOU!
Message-ID: <20000302105256.A23108@devware.com>

It used to be that I was so open minded when it came to web
technologies.  I used to say "Oh yeah, pick whatever you want, we can
do it in that."  I used to say "No problem!  We can use your scripting
technology!  It's just as good as any other."  And I would, and they
would, and we did.  And we'd all stand around and say "Yeah
man... that's cool."

And then Zope entered my life.  And NOW I simply can't think of
virtually any project that Zope wouldn't do a better job of serving
than those *other* technologies.  It's very frustrating when every
time you see a project you think "Oh, Zope would make that SO much
easier!"  Especially any time someone mentions the word "Database" and
"Web" in close proximity.  The truly frustrating part is staying
focused on the problem-space when you have such a fun technology to
play with.

Now in some ways I'll admit, this is an exaggeration.  Obviously,
there ARE lots of cases when Zope isn't appropriate, but I just wanted
to shout out a big thanks for developing such an awesome system that
makes developing apps so easy to do.  Now if I could just get my mind
off of it's possibilities long enough to evaluate those OTHER
technologies objectively, then I'd be in good shape. ;D

Subject: [Zope] Oedipus 0.06 released
Message-ID: <200003021716.MAA27689@amarok.cnri.reston.va.us>

I've made a new release of Oedipus, a Python package for presenting
data from the Open Directory Project.  
 
http://www.mems-exchange.org/software/python/oedipus/   

In v0.06, The improvements to the ODP code itself are pretty minor.
The major milestone is that, after some diligent sleuthing,
Jean-Claude Wippler tracked down an obscure bug in MetaKit that I was
tripping over.  A patch for MetaKit 2.0 is included in Oedipus 0.06,
so for the first time you can actually handle a complete ODP dump.
You'd better have 400Mb of disk space for the resulting data file,
though, plus 500Mb for the source XML files, plus 4-5 hours of
processing time (at least on a 550MHz Linux box).

The exported ZClass product still doesn't seem to work, though; if you
untar it in a new Zope installation, no Product is added when you
start up Zope.  Anyone else notice this problem?

Me too, I think. I haven't investigated this more deeply yet
but I noticed that all new News items created since March 1 in
the PTK portal I've been playing with get their
dates set back to 29 Feb the moment they are modified
(by being approved, for example).

Hello all -

I am unable to connect to my Zope 2.
I am running Linux 2.2.14, with Apache
I am new to Zope and pretty new to Linux

I installed Python 1.5.2, then installed Zope using "python w_pcgi.py"
I entered ./start
It worked...  for a while... until I shutdown...
When I restarted, Zope wasn't available.  I went back to the Zope directory
and tried ./start again but the script seems to lock up after displaying the

I was so happy when I got it running, now I'm incredibly frustrated!  Please

I can supply my Apache conf files if necessary...

Many Thanks,  Eric.

apologies, ignore my pervious posting, try instead:

<dtml-let newid=id>
  <dtml-with "_[newid]" only>

Subject: [Zope] [Newbie]  SQL database support on NT
Message-ID: <NDBBLMHEELDKLGHEEMJPIEMMCBAA.bac@ivc.com>

Hello All:

I'm just beginning to play with zope and really like what I see.  No Zen yet
but it's coming.

The project I'm working on must use NT as the server, much to my
displeasure.  I need to select a SQL database for the project and need to
find one that will work and play well with zope.  Searching through the
Guides and How-to's has left me a big puzzled.

Looking at the "Database Adapter Roadmap", it looks like there isn't a
direct adapter for SQLServer.  is this correct?  Will the Oracle adapter
work on NT?

If not, is my only choice to use the ODBC adapter?  Or the ZJetAdapter for
MS-Access (which I don't think would be sufficient for my needs)?

Any suggestions for database selection on NT will be appreciated.

Thanks,

Brad

It looks like you are indeed running the query multiple times. Unless you
are changing the data at some point internal to the process, which would
require your to "refresh" the results in order to have current data, you
could try:

<dtml-in sqlMethod query=start_query>
Do some stuff
Do some more stuff
Do even more stuff
</dtml-in>

Youd be "recycling" the result set, and sparing the DB backend.

I'll give that a try.  If I wanted to add a method to the catalog wrapper, 
is there a non-invasive way to do this or would I have to modify some 
standard Zope code to work differently?

We have been running an in house (approxiamately 100 users) contact management and order process site on NT 4.0 for several months
now using Visual FoxPro as the back end database (on a different NT machine) via ODBC and have had few problems. The zope machine is
a dell P3-400 w/256megs of ram. The db machine is a generic P2-200 with 512megs of ram. They are connected through a 100mbits
intelligent switch. However both machines now have dual port 100 mbits cards and we are in the processs of using the extra port on
each card to direct connect the 2 machine.

Our application is db intensive (every sql method involves at least 1 wrapper call to determine the AUTHENTICATED_USER's access
level) Unless there is network congestion and can display an order form (2 frames each the result of 5 to 10 sql methods) in about 2
to 3 seconds. (Response is 3 to 6 times faster via browser and ZOPE than throught the VFP apps that were originallly written to 2
this. )

VFP makes a very fast backend because if you are using only indexed columns and/or expressions the it can determine the record or
records entirely from the indexes meaning it never pulls data out of  the data file till it knows exactly which records to get.
Single record lookups - even with complex queries - are almost instantaneous.

LoginManager now has this capability. The loginForm is passed
"needroles", the list of roles one would have to have one of to perform
the action that prompted the login. Thus you could do:

 <dtml-if "'Member' in needroles">
  ... member login form ...
 <dtml-else>
  ... manager login form ...
 </dtml-if>

(note that 'Manager' is likely allowed to do both member and manager
things, and thus checking "'Manager' in needroles" would be true in
either case and not do what you want)

Hey guys. 

I'm currently in a minor bidding war with the Oracle group here over
whether we re-implement some intranet programs in Zope or in Oracle
WebDB. I've got them on just about everything, except calling stored
procedures. 
Now, I know that ZOracleDA supports Stored Procedures. So I'm guessing
that something like the following would work, but I'll be buggered if I
can figure out how. 

ZOracleDA Connection : oracle_da
External Method : find_target(search_string)
Oracle Package : Program1
Oracle Procedure : Proc1

def find_target(self, search_string):
  c=self.oracle_da.cursor()
  s=self.oracle_da.procedures.Program1.Proc1(search_string,c)
  return c.fetchall()

Am I missing something? I can't even get -- 
>>> import DCOracle
>>> dbh=DCOracle.Connect('user/pass@DB1')
>>> c=dbh.cursor()
>>> sth=dbh.procedures.pgm1_api.find_target('spam',c)

Message-ID: <38BEDC9C.734F4754@exceptionalminds.com>

Hi all,

I have a form on which I am having some interesting performance issues,
I think, but am not sure that it is my extensive use of SQLSession
variables throughout the form.

I have a single page data entry form where almost every field  gets
stored in the SESSION. This form can take from 9 to 15 seconds to
display. When all my other forms take 1 to 3 seconds this is a
significant slowdown.

I am curious as to what methods may be used to reduce calls to
SESSION['varname'], or if I am even barking up the right tree.

Thanks.

In the 'utilities' directory of Zope there is a tool called

ok.  by "a ZODB" do you mean that the call in my external method
is trying to reopen the ZODB zope is using?  i'd assumed i was 
crating another one, with a separate FileStorage.

ok, then how does code in my external method get at that?
that is, how do i create an object and stuff it in the DB?
all the code examples i've seen follow the pattern in GetPeople().

how do i do this?

i get the feeling i'm just missing something, perhaps thinking like
a python programmer rather than a zope guru.  i feel like there's 
some big obvious point that has escaped me, and i'm waiting for the
big "AHA!".

so, one more try.  given the following external method:

import ZODB, ZODB.FileStorage


def GetPeople( self ):
	"Return list of people in DB"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( 'TestDB.fs' ) )
	connection = db.open()
	root = connection.root()
	people = []
	for key in root.keys():
		people.append( root[ key ] )
	return people

if __name__ == '__main__':
	for person in GetPeople( None ):
		print person.name, 'is', person.age, 'years old'


referenced from a DTML Method:

<dtml-in "GetPeople()">
	<dtml-var name> is <dtml-var age> years old.<br>
</dtml-in>

when i restart zope and view the method, it works once, but shows
no persons.  the second time, it fails with the traceback.

what do i change to make it work?

thank you for your patience.

I have not followed the thread but reading this particular posting, seems
to me that you cannot do what you want to do (at least in a
straightforward way). Importing ZODB declares all kind of global
variables/methods, an important one being get_transaction() which returns
the current transaction. So if you do a get-transaction() in your external
method which transaction should it return? And how would the two
transaction managers interact? Couldn't you just register your root object
with the current ZODB (the one Zope is running), by just setting it as an
attribute to the root object?

Again I have not followed the thread so I may be way off topic.

Thanks for investigating this - because TimeStamp objects are 
used in the object database, I don't want to make any changes 
to this yet until I can talk to Jim and verify that the fix 
won't have any impact on ZODB code (mon. morning probably).

Last I checked, setting an SESSIOn variable immediately did an update
on the RDBM which would explain the slowdown. I do not know what the
current situation is but I remember Anthony mentioning he was thinking of
changing it. You might trying playing with the source code and store all
changes to SESSION in a volatile attribute and call the SQL method at the
end of the transaction only (at least this is how I do it in FSSession).

Your only choice is the ODBC adapter if you want tyo use SQL-server.
We're running Zope on a NT server with SQL-server as database.
It works very well.

Thanks... but I think I really need to raise an error:
I want to invoke the redirect in the standard_html_header,
so if I use <dtml-call "RESPONSE.redirect(url)">, only
the header will be redirected (I think...).

Another, slightly related question: On my zope, whenever 
there is an error, the whole Traceback is printed on
the error page, and this doesn't seem to be part of the
standard_error_message. Does anyone know how to hide it,
or to put it in a html comment, like www.zope.org does?

Thanks,

Stefan.

If a FieldIndex is treated as atomic, it shouldn't go trough
the Splitter, right?

I found out that an hyphen in a field indexed as FieldIndex
breaks the index (this field is just not indexed, it seems). A
space works. Weird.

I was working with my ZClasses today and was confronted with something 
which seems strange.  I was editing a method defined in my ZClass when I 
tried to click on the "propertysheets" link displayed at the top of the 
edit screen:

DTMLMethod at  / ControlPanel / Products / <product> / <zclass> / 
propertysheets / methods / <method name>

When I clicked on the link, a basic authorization dialog was displayed.  I 
was already logged in as the superuser.  Why am I getting an authorization 
dialog?

Mostly just curious.

Thanks.

I guess it depends on what database you are using. If your
database is a remote server hooked up through TCP/IP port,
too many calls to SESSION could be bad. Also, if the session
data is large, during the transimission many packets have to
be send.

I don't have an answer... maybe you could describe first
what database you are using (Gadfly on the same machine?
remote database?), do you do many retrievals and updates?

------------------------

In the code SQLSession.py, there is a 'caching' variable.
SQLSession seems to cache variables that are already
retrieved or are recently updated. Try to set 'caching'
to 1 and see if that helps.

------------------------

As Pavlos Christoforou said, another strategy is to
have a single session data variable (a dictionary,
for instance), and then retrieve it, say, in your
standard_html_header and store it in your standard_html_footer
(or their equivalents.) This way you only need to access
the database twice per request.

------------------------

Please post back... I am also very interested. You
can also time performance by calling time.time()
in Python or <dtml-var ZopeTime> in DTML. I am
curious in the source of the problem... It would be
nice to find out whether the time is spent in each
database query or in TCP/IP packet splitting/joining/waiting.

regards,

Hung Jung

PostgreSQL running on the same box as ZServer.

Thanks for this input. I will go and take a look at it. I did not know
it was there.

Now this in an interesting idea, but all my attempts to computationally
build a dictionary within Zope have gone to naught. I would love any
advice on this as I believe it could very well be the key to this
problem.

This will redirect the whole page, as it gives a client-side redirect.

it only does this if you're logged in, otherwise it puts it in a comment
(or displays your standard_error_message)

This ist a typical Y2K bug, located in the module TimpeStamp.c, 
as I suspected earlier.
 
Since nobody followed my hint from earlier this day so far, I took 
the opportunity to dig a little deeper, learning how to build and 
replace a python extension on the way.

Given how little documentation there is, I don't claim having 
understood anything about, but noticing that the function

static double TimeStamp_abst(int y, int mo, int d, int m, int s)

gets called with y=100 (not 2000), 

changing the leap yar calculation

 l = y%4==0 && (y%100 != 0 || y%400==0);

to

 l = y%4==0 && (y%100 != 0 || (y+1900)%400==0);

in that function fixed the problem on my system.

erm.. one question... are you running Squid?  Or anything else on port 8080?

try "telnet 192.168.1.100 8080" and see what it says.


p.s.  if you want ZOPE to start on bootup, i put this in my /etc/rc.d/rc.local
file (I'm running RH6.2.. your rc.local may be elsewhere, or a different name):

/usr/local/Zope-2.1.3-src/start &

I actually run ZOPE as user 'zope', so i use:

su -l zope --command=/usr/local/Zope-2.1.3-src/start &

This is the detail I did not notice, previously. I thought you were trying
to store objects in your Zope ZODB; I didn't notice that the filename you
were passing to FileStorage was not Data.fs.

Sorry.

I don't understand why the problem is manifesting as it is, but I got your
code to work by modifying your code as follows:

- for key in root.keys():
-         people.append(root[key])
+ connection.close()
- return people

Opening a connection without closing it is a Bad Idea. I just can't figure
out what this has to do with the lock file on the database. I figured when
I closed the connection it was deleting the lock, but this is not so. So,
I remain confused. ;-)

Hope this helps!

That's why I didn't suggest a fix in my first analysis. I don't know 
anything about the internals of the Zope object data base (hey, I 
learned about Zope only about two months ago, so what do you 
expect?). So I don't even know whether it's just a problem of 
displaying the wrong date, or whether wrong time stamps are 
written to the data base. In the latter case, most people would 
prefer to have that bug fix yesterday. Inconsistent dates in a data 
base are a serious problem, and it's getting worse as longer it lasts.

okey dokey.  the setup is not that big.  we're just starting out and are just
feeling our way here.  what we have:

a PIII 500 M compaq 5500 ,smartscsi with RH 6.1, zope 2.1.3. i tried running
zserver with fast cgi but it choked with high load.  so, in the end, it's
apache with pcgi.  so far, it handles all the traffic beautifully.

what we want, however - reliability, availability of our site, so that's where
we need to look now.  caching is also another matter.  currently we enabled
apache expire module, but  not quite sure whether that would have any effect on
pages served by zope.

yes, and are you going to use sql in the future?  or just stay with zodb?  i
would think going with sql is better in the sense that most of us have that 2G
fs limit, and putting data in sql would help separate data from zodb.

Hmm. ZClass products aren't automagically imported; when exported, turn into
zexp files, either on the client machine somewhere or in the server's
$ZOPE_HOME/var directory.  To install them on another server, on must:

  * copy the *.zexp file into the new server's $ZOPE_HOME/import directory

  * import the *.zexp file into the "Control Panel | Products" folder.

You don't have to restart the new server, either, unlike "normal" Python
products.

Unless somebody borrowed Guido's time machine and retrofitted Butch Landigan's
ZPack proposal, that is?

Tres.

Greetings.

To start imapd should be set to run vie inetd. In the /usr/doc/packages/pop
directory look at the BUILD file. This has the information for setting up
inetd.conf to work with the imapd. In short you need to edit a few lines of the
inetd that comes with SuSE. Mostly you will need to uncomment the imap lines
they should look like this:

imap2   stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/imapd
pop3    stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/ipop3d

This will allow you to use the imap server or the pop server if you want to.

You may also want to check your configuration with a regular IMAP compatible
mail client like Netscape Messinger. FWIW I'm running WorldPilot on my test
server that is SuSE 6.2 (upgraded from 6.0) and works well.

Good Luck!
Jack

I checked my /etc/services file and it isn't showing anything connected to
port 8080.  Is there somewhere else I need to check?

//
// try "telnet 192.168.1.100 8080" and see what it says.
It says: "telnet: Unable to connect to remote host: Connection refused"

Then I added the "/usr/local/Zope-2.1.3-src/start &" line to my
/etc/rc.d/rc.local file, rebooted, did a "ps -ax" to see what processes were
running, saw that "z2.py -D" (in there 2 times).

So, I tried to telnet in agian and this time it said "Connected to
192.168.1.100"

Next I tried to connect to "http://192.168.1.100:8080/manage" with my
browser...

IT WORKED!!!!

Thanks a million Curtis!  I guess I just needed to add the line to my
/etc/rc.d/rc.local file and reboot!  YAY!

OK, now I need to get to work.

Eric.

I have an html document that I created outside the Zope env. that has a
table. One column of the table is blue, the background of the document
is white. I can see the work I have done fine when I look at the
document in Netscape, but when I load it into zope and look at it, the
bgcolor for the table column isn't there. Am I doing something wrong, or
is this a zope feature?

Hi,

What is the difference between <dtml-call "...."> and <dtml-call ...>.  For
instance, if I have this directory structure:

|
+-base
    +-subfolder

from base,

<dtml-call subfolder.manage_addFolder(...)> doesn't add any folders, while
<dtml-call "subfolder.manage_addFolder(...)"> behaves as expected. It took
about an hour of experimenting before getting this right. Could someone
explain what is the difference here?

Thanks.

I would like to understand the source of your problem, too.

However, I think there is a misunderstanding here. In TM.py,
_registered is a class data attribute, which is typically
a trick for "initializing" Python instance data attribute.
That is, unless you explicitly do something like

  TM._register = 1

the class variable would never change. That is, TM._register
is always None. Always always. So there should not be any
problem in thread interference.

If x is an instance of TM (or an instance that has TM as
an interface, in the case of multiple inheritance), if you
look at the dictionary of x, i.e: x.__dict__ , you will see
that initially x does not have an attribute _register in
its own dictionary. However, x._register is a valid reference,
because it borrows from the class attribute. The statement:

  print x._register

would print out 'None'. As soon as you assign a value to

  x._register = 1

you create an attribute in the dictionary of x. That is, a
new item is added into x.__dict__ , which is totatally
independent of TM._register. So TM._register remains as None.

I'd like to take a look into it, too. But first I'll have
to learn what the flags _v_registered and _register mean. :(
I don't even understand what is a "transaction" in the sense
used by the transaction manager.

If I understand correctly, the definition of "transaction"
that you would like to use is one single HTTP transaction,
which lasts from the beginning of a foreign HTTP client
request till the end of Zope sending out the reply.

The question is: is this the same definition of "transaction"
as used by the transaction manager? Why would anything be
stored in ZODB?!? The HTTP "transaction" should not have
anything to do with ZODB database "transaction". The
"versions" that are stored in ZODB, are they FSSESSION
objects?

I'd like to look into all this. :)

regards,

Hung Jung

Calling tags with and without quotes follows mostly the same convention
throughout Zope. A tag without quotes, such as:

  <dtml-var myMethod>

is equivalent to:

  <dtml-var name=myMethod>

This says, "Include the variable with the name myMethod." The alternate
form is:

  <dtml-var "myMethod()">

which is equivalent to:

<dtml-var expr="myMethod()">

This says, "Include the result of the Python expression in quotes,
myMethod()."

In your specific case, dtml-call without quotes is equivalent to
using the name form, and thus does nothing. There is no attribute or
method called subfolder.manage_addFolder(...). Note that Zope would be
looking for this, literally, and would not interpret the period as an
application of a method to an instance.

Using the dtml-call tag with quotes is equivalent to the expr form, and
will thus interpret the period appropriately.

To convince yourself that this is the case, try including a DTML Method
using the expr form without parenthesis:

  <dtml-var expr="myMethod">

puts this in the response:

  <function myMethod at 8071cf8>

If you view this in a browser, you will not see it because your browser
will try and interpret it as a <function ...> tag, which, of course, does
not exist.

Hope this helps.

From my tests I am pretty sure the right dates are stored. It is just the
timeTime() representation of those dates that is wrong.

However, as you pointed out, the methods that provide the representation are
a bit confused over what format the year portion should be in when called.
This,and the fact its something so deeply part of the ZODB makes a fix
something that Jim can do.. =)

Again, greetings...

So I kept looking at what I had, and some things just did NOT look right.

So I fiddled.  I wrangled.  I bashed it with various bits of office equipment. 
And I got it to work!

here is a cutdown of what i used:

    <dtml-in "somQueryHere" size=5 start=qs>
      <dtml-if sequence-start>
        <dtml-if previous-sequence>
          <tr><td colspan="2"><a href="past_orders?qs=<dtml-var previous-sequence-start-index>">
              Previous <dtml-var previous-sequence-size> orders.</a></td>     
          </tr>
        </dtml-if>
       </dtml-if>
      <tr><td>STUFF</td>
          <td>FROM</td>
          <td>ITERATED</td>
          <td>QUERY</td>
          <td>HERE</td>
      </tr>
      <dtml-if sequence-end>
        <dtml-if next-sequence>
          <tr><td colspan="5"><a href="past_orders?qs=<dtml-var next-sequence-start-index>">
              Next <dtml-var next-sequence-size> orders.</a></td>
          </tr>
        </dtml-if>
      </dtml-if>
    </dtml-in>

it's much simpler than the example in the DTML book (IMHO), and it would be
faster in making only ONE call to whatever query it is you're using, not 3.

I'm not sure who is in charge of the DTML reference manual, but if i get a
moment i will be forwarding this code snippet on to them.

How could I dump all names in REQUEST for debug? The quick reference reval

Message-ID: <007701bf84f3$98a60640$770da8c0@bbs>

I think it worth to encourage zopelist to move more things to the
client-side by modify a Zope fresh installation.

I found out there are many things hard-coded in
python or dtml in zope's source.

There are some things which can be do better in the client side. For
example, there were many dynamic folder tree writen in javascript which can
be more responsible than the zope tree tag (which the change of the tree
state require the help from server).

I would like to urge zopelists to explorer the client side authoring which
could actually give zope a dramatically change.

1. Remove those hard-coded parameters from the source and placed them in the
folder tree as attributes which can be modified or overwrited by manage
interface and acquisition.

2. Define the basic css (which zope.org have one) as default elements with
the fress zope install.

3. Make the current Zope tag comply with xml standards : they should end
with /> or accept an end tag.

4. Collect open-source javascript codes and convert them into zope products
(like tree).

To build a dict in DTML, try something like this:

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('mydict',{})">

<dtml-call "mydict.update({'e':7})">

<dtml-with mydict mapping>
[<dtml-var e>]
</dtml-with>

<dtml-var standard_html_footer>

Plain python assignment won't work, as a "=" in python is a statement, 
and statements are not supported, only function calls.

to remove a key, use <dtml-call "del(mydict['e'])">

That could be good idea.

What would it add ? But a CSS-method or similar would be a nice addition.

Or even a general TEXT-method, with Content-type: as an attribute, so I don't 
need to write <dtml-call "RESPONSE.setheader('Content-type'. .... for all 
non-html methods

Why ? As has been revealed in several discussions before, it would be very 
limiting for DTML to force compliance to XML (dtml tags inside html tags, etc)

Making it only superficially similar would just confuse people.

If you could integrate it nicely with other parts of zope it would be a
welcome 
addition. But I doubt it would be easy, but if you can come up with a nice 
implementation, I'm sure it would be accepted in contrib.

IMHO this would be a very bad idea, because not all browsers are able to
use javascript. 

for example the tree tag works perfectly with lynx. This is really very
nice, because often we can't do many things with text only browsers, but
the tree tag is very powerful and lynx can use it: it's cool.

IIRC the recommended way was to use

<dtml-var REQUEST>

or perhaps

<pre><dtml-var REQUEST></pre>


It was further recommended to make a method called DEBUG in your root 
folder containing the above and set permissions so that only managers 
could use it.

You may want to check out the Zope-Mozilla initiative (and the related
Model/View discussion), which does something like this. It's on
http://www.zope.org/Resources/Mozilla. As this is Open Source,
contributions are more than welcome.

Another tree difficulty:

I have a tree widget in a page.
When branches are expanded or collapsed the
view you get in the browser moves.

Now I know this is somewhat unavoidable but
can anyone think of a way to limit the effect
for example some way of making the text above
the newly-expanded bit stay still and just
re-rendering that below instead of shifting
everything around?

I am using Interbase 5.6 with ODBC.  It sucks. 2-3 x a week the ODBC
connection gets lost, and the Zope ODBC adapter refuses to reconnect.  

It usually happens after I enter the management screens as well.

I have to shut Zserver down, and restart it.   I think the problem must
be the ODBC driver supplied by Interbase Corp.

I'll probably shift it over to MS Sqlserver as people don't seem to
report problems there.

[ preventing acquisition within a tree-tag ]

After going through the archives my third (and hopefully better tested)
trial with this :-)

In your Extensions directory create an external python method with this
code:

def prev_acqu(self, prop):
    if self.__dict__.has_key(prop):
       return getattr(self,prop)
    else:
       return ''

add it with the id prev_acqu (or anything else you like better) to a
folder in the acquisition path.

In your tree code do:

   <dtml-var "prev_acqu('rubbish')">

If you choose a different id, of course you have to take it here, too. 

Apologies again for jumping into this thread without exactly verifying
my code examples yesterday,

Forget it, its a mad idea.  I was dreaming up some
mad-brained scheme using targets (so eg each
expansion could ensure that the very top of the
page was visible in the browser) but its crazy.
I need a weekend.

That is not "locked up" -- that is the normal "blocked waiting for requests"

Because the FTP server code is in Python, the chances of this 
being a real classic "buffer overflow" (of the sort that can 
start to overwrite unintended memory) is slim (I expect that 
the worst you could do is send something so long that it consumes
all available memory and causes Python to raise a MemoryError).

We should look into the handling of those commands though. I don't
manage the FTP code so I don't have enough deep Zen to know what 
the "correct" behavior is, but it seems that if it's giving a 
false positive then something is probably not being handled 
totally correctly. Can you make an post in the Collector about 
this so that it doesn't get lost in the flow of the list?

Thanks!

FWIW, I'm 99% sure that it's just a formatting/display problem. I'm

You might also look at TimeStamp_yad() (line 117 of the same file in 2.1.4)::

  static double
  TimeStamp_yad(int y)
  {
    double d, s;
  
    d=(y-1)*365;
    if (y > 0) 
      {
          s=1.0;
          y=y-1;
      }
    else
      {
        s=-1.0;
        y = -y;
      }
    return d+s*(y/4-y/100+(y+300)/400);
  }

I _think_ the last line should be::

    return d+s*((y/4)-(y/100)+(y/400));

"every fourth year, except century years, except every fourth century".  Perhaps
the original was "working" to compensate the base 1900 vs. base 0?

Weirdness...

I've almost got mod_pcgi2 setup to serve my entire site fronted by Apache
but I've run into one final snag.

When I access the home page of the site I notice that the BASE HREF
returned by Zope is saying its http://XXX/index.html/

Apparently Apache is appending the Index name for the folder?

I tried Options -Indexes but this didn't solve it.

Anyone have a valid configuration for this situation that I can take a
look at?

Thanks,

It's also worth mentioning that when you do this to call DTML Methods and
External Methods some things automatically get passed in. When you use the
expression form, these things are not passed in. The most important thing is
that the namespace is passed along to DTML Methods and this() and REQUEST
are passed along to external methods. I haven't looked at the python source
to know exactly what is passed in these cases, but you generally will get
what you want if you do this for DTML Methods:

<dtml-var "myMethod(_.None, _)">

and this for external/python methods:
<dtml-var "myMethod(this(), REQUEST)">

   This has nothing with mod_pcgi2 or Apache - it is Zope who adds BASE.
May be you can eliminate it with SiteAccess. It seems you are trying to do
virtual hosting with Apache, and Zope is not capable yet of virtual
hosting, but SiteAccess is one method to helps.

Subject: [Zope] Trouble with dtml-in
Message-ID: <38BFDB65.3AFA8796@lunateks.com>

I'm having trouble with using dtml-in in batch mode.

A syntax like this:

<dtml-in objectlist size=1 start=qs>
  <dtml-var sequence-item>
</dtml-in>

Works properly when qs=1 or qs=0 (treated as 1). Anything more than 1
causes it to ignore the "size=1" setting and loop through all the
elements in the list. The "next" and "previous" parameters exhibit this
problem too.

I can't understand what I'm doing wrong. I'm using the exact code as in
the DTML reference (except for the size of 1).

I upgraded from Zope-2.1.1 to 2.1.4 to see if this problem had been
fixed, but no luck yet.

The only way I can find to get around this is to remove the size=1
parameter and use a <dtml-if "_['sequence-index']-1==qs"> to make the
batch work.

A colleague insightfully commented that while Dynamo has a high bullshit
factor, this is the reason it sells.

Take a look at this screen shot:

http://www.atg.com/news/images/screen-shots/systemconsole.gif

Dynamo is an expensive, closed product with a promotional web site that
smells like a million-dollar penthouse office space, replete with glass
walls and postmodern sculptures. It smells a bit funky, and the people
are possibly evil, but the product is of high quality, and it sells. And
because it sells, many people use it, and because so many people use it,
skilled developers exist in large numbers. Unfortunately, I can't say
the same of Zope.

Speaking of which, SNMP support for Zope would have been nice. Then we
could import the numbers needed to build monitors like the one featured
in the screen shot.

Sorry; I wrote sloppily and shouldn't have said "exported".  This is
the .tgz file produced when you make a distribution of a ZClass-based
product.  For that, you do need to restart Zope -- but the new Product
never shows up.  I haven't yet dug into Zope to see if this feature is
broken, or if something else is going on.

Subject: [Zope] Finding matches between two lists
Message-ID: <3.0.6.32.20000303091400.009538f0@pop.dnvr.uswest.net>

Hey all!

	This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

	---------

	The layout:

	Most of my code is in a Python Product, but there is still a bunch of dtml
used.

	I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

	Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

	---------

	The DTML attempt:

	I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

	<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">
                   <A href="<dtml-var site_url>/<dtml-var id>"><dtml-var
sequence-item></a>, 
                 <dtml-else><dtml-var sequence-item>, 
                 </dtml-if>
              </dtml-in>
            </dtml-if>
          </dtml-in>
        </dtml-with>
    </dtml-if eventnames>


	---------

	The Python attempt:

	So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

    def list_dj_list(self, namelist):
        """ should return a list of names & IDs from a list of names
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rnames = []
        for i in range(len(namelist)):
            rnamelist = rlist
            rname = filter(lambda x,p=self,s=namelist[i] : p.data[x].name
== s, rnamelist)
            if len(rnames) == 0:
                rnames.append('None')
            elif len(rnames) == 1:
                rnames.append(rname)
            else:
                rnames.append('multiples')

        return rnames

	---------

	The question:

	How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

	Thanks for any help!

If I understand you properly, then I think you'll find the Squishdot product
perfect for experimenting with a "real" zope site. Squishdot is a product
that emulates the functionality of Slashdot. You can read about Squishdot
and download it at

http://www.zope.org/Members/butchland/Squishdot

Make sure you install the TinyTable product too for the full tour.

As a post-installation test tool, it would be great to have a sample DTML
web site.
Does anybody have such a small collection of DTML pages to donate to the

Funny, I had never heard of Dynamo before you mentioned it here. 
Fortunately, I can't say the same of Zope ;)   I think you underestimate
the actual numbers of people and sites that use Zope.  I also think that
you are creating FUD so that you can get a feature you want to see 
implemented by the folks at DC.  Truly bad taste.

Please no.  There is NO reason to pollute Zope with something as insecure
as SNMP.

Subject: [Zope] 'helper' classes in External Methods
Message-ID: <v04220803b4e59f28a438@[128.240.198.13]>

Can someone give me a pointer to what these helper classes actually 
do? Can I use them to setup lists and dictionaries that will be used 
over the lifetime of the Zope server?

This is an example from an external method that Pavlos posted a while back.

class MCQ:
         ''' helper class for MCQ system'''
         def __init__(self, score):
                 ''' constructor'''
                 self.score = 0
                 self.total_score = 0

What I would like to do is load up a template_lookups dictionary with 
quite a few entries;

for template_id in self.Actors.RENDER.objectIds():
         renderer = eval("self.Actors.RENDER.%s" % template_id)
         template_lookups[template_id] = renderer

Thing is, I need access to the ZODB in one of my methods later in the 
module and so the above code doesn't work (too many 'selfs'!).

Anyone got any ideas?

Well, I am doing Virtual Hosting via Apache, but I'm only running one site
per instance of Zope.

Isn't this possible with pure mod_pcgi2?

Note that the servers listed as runinng Zope on Netcraft, are those that run
straight ZServer. Those sites that run Zope behind Apache, IIS, Zeus, or any
other webserver, will be listed under those webservers. So, a small
percentage of the number of Apache sites on the web, runs Zope.

From my personal expirience, I find that a lot more people run Zope behind
Apache, instead of pure ZServer. So, the number of Zope sites is a
significant factor higher than the 300 listed by Netcraft.

For an example, go to:

  http://www.netcraft.com/whats/?host=www.zope.org

You'll see that it is listed as running Apache (which it is).

Message-ID: <38BFF7BB.8EA2DA2B@vt.edu>

Hi, ed.

I think I am a bit dense today, so could not quite understand completely
what you are doing, but

If you want to find matches between lists, there is a cool thing in
Python that can possibly help you.  

Let's say I have two lists, list1 and list2, and I want to know what in
list1 is in list2, which is I think what you are going for.

list1 = ['n', 'b', 'r']
list2 = ['f', 'd', 'b']

def intersect(lista, listb):

    tmp = []
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp.append(anitem) #if there, append to the temp list
    return tmp                 #return the temp list

print intersect(list1, list2)  #should be ['b']

If I want no dupes, (if 'b' is in list1 twice, it will be returned
twice) I probably would use a dictionary instead of a list and return
the keys, e.g, 

def intersectnodupes(lista, listb):
    tmp = {}
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp[anitem] = 1    #if there, throw it into the doct
    tmp1 = tmp.keys()          #get the keys (arbitrary order, alas!)
    tmp1.sort()                #the keys are in arbitrary order no
longer
    return tmp1                #return the unduplicated list

In DTML, you can use the 'if athing in alist' thing too:

<dtml-call "REQUEST.set('list1', ['n', 'b', 'r'])"> <!-- or use your own
lists -->
<dtml-call "REQUEST.set('list2', ['f', 'd', 'b'])">

<dtml-in list1>
<dtml-if "_['sequence-item'] in list2">
<dtml-var sequence-item> <!-- do something with the things in list1 that
are in list2 --> 
</dtml-if>
</dtml-in>

Message-ID: <3.0.6.32.20000303184315.0093e620@poirot>

Hi,

I'm once again trying to get further in my test products.

* I've created a catalogAware ZClass, called KBItem
* KBItem contains an external method with id manage_afterAdd

Now, I can add KBItem instances in Zope without problems, BUT!

when having a ZCatalog inside a folder with the id Catalog and then try to
create a KBItem instance, I get following error (where testje is the id of
the KBItem I try to create) :

Zope has encountered an error while publishing this resource. 

           Error Type: ValueError
           Error Value: Uncatalog of absent id 'TEST_Folder/testje'

Help! I don't know what I'm doing wrong or what is happening!
What does it mean and what can I do?

Thanks in advance,

Tom.

if you have 2 queries one of which returns tuples containing events and usernames,

Subject: [Zope] Finding matches between two lists


Hey all!

This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

---------

The layout:

Most of my code is in a Python Product, but there is still a bunch of dtml
used.

I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

---------

The DTML attempt:

I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">
                   <A href="<dtml-var site_url>/<dtml-var id>"><dtml-var
sequence-item></a>, 
                 <dtml-else><dtml-var sequence-item>, 
                 </dtml-if>
              </dtml-in>
            </dtml-if>
          </dtml-in>
        </dtml-with>
    </dtml-if eventnames>


---------

The Python attempt:

So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

The question:

How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

Thanks for any help!

I tried this:

The question thus:
Why are the two different?

Anyone?

Hi Tom,

This might be because the CatalogAware class uses the manage_afterAdd hook
itself (CatalogAwareness.py).

In _your_ manage_afterAdd(self, item, container), try this (untested):

def manage_afterAdd(self, item, container):
      # do whatever want to
      CatalogAware.manage_afterAdd(self, item, container)

Hope this works.

Great idea!

However, no I get this error :

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: CatalogAware

Do I've to place somewhere an import of the CatalogAwareness library?
I'm afraid my knowledge of Python is to low to solve this correctly. Any
ideas?

Tom.

Hi,

I installed Zope 2.1.4 on my RedHat 6.1. I wanted to change the password given
by the installer. I tried : 
python zpasswd.py -p=mynewpassword access

Everything seems ok. I have new file called access which looks like the older
one except for the 'password' part.

1 - Do I need to restart zope in order to have the new password be effective.

2 - Even if I restart zope, i cannot use my new password. However if i replace
the new file called access by the old one, i can acces to the zope management
screen.

What have I done wrong?

Message-ID: <3BA3A8B61E4ED211ABB900A0C9615FE639C822@sev-mail.gtri.gatech.edu>

Okay, I'm new to Zope (3 days), but I was having such success with some
simple things that I thought that I could handle something tricky - I've
been working at it for a day now.

What I would like to do is present two selections (Division and Team) that
are populated from an ODBC connection.  I can do the population fine,
normally; but the trick is that I'd like to have the Team selection
dependent upon the Division selection (on the same web page).  I realized
that I couldn't do this on a simge form (or can I?), so I've assigned the
two selections to two forms.  I'm putting the two forms on the same page for
aesthetic (stubborness?) reasons.  Here's the code for the first form:

<form action="index_html" method="get"> Division:
  <select name="division" width=30 value="">
    <dtml-in sqlShowDivisions size=50 start=query_start>
      <option> <dtml-var age_group>
    </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>


This part works fine.  When I submit the form, the same page is regenerated
(with the 'division' parameter passed in).
One of my many failed attempts with the second form (which is also in
'index_html') is as follows:

<form action="TeamSchedule" method="get">
  <dtml-var division missing="Undefined"> Team:
  <select name="team" width=30 value="">
     <dtml-in sqlTeamsInDivision size=50 start=query_start>
        <option><dtml-var name>
     </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>

my sqlTeamsInDivision has 'division' as its only parameter.

When the user first enters the document, he gets an KeyError on 'division'.
I understand why this is so (the division parameter doesn't exist yet), but
I can't seem to work around it .

I tried changing the sql parameter to divisionname and changing the
<dtml-in> tag to:

<dtml-in expr="sqlTeamsInDivision(divisionname='<dtml-var division
missing>')" size=50 start=query_start>

and the error goes away, but the returned list is just blanks.  How should I
be handling this?

Also, when this form is submitted, it calls TeamSchedule with the 'team'
parameter, but I need to also pass the 'division' parameter.  How do I do
this?

Thanks in advance.

Subject: [Zope] Installation trouble on Solaris 2.6
Message-ID: <NDBBLONFDKEIFDBOFGJMCENCCCAA.ztf@one.com>

Hi all,

I'm trying to install Zope from source on a Solaris 2.6 system,
and I'm running into problems.

When I try "./start", I get the following error:

$ ./start
$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

/opt2/local/zope/Zope-2.1.4-src/lib/python/ExtensionClass.so: symbol
PyImport_ImportModule: referenced symbol not found

I am new to Python, so it's less than obvious to me what is going
on here.  It looks like the ExtensionClass module is failing to
import, but I have no idea how to go about fixing this.

[Yes, I know about the precompiled Solaris 2.6 binary.  However,
I eventually will need to get this running on a Solaris 2.5.1 system.
Also, as far as I can tell, the binary release is not set up for
Apache integration, which is something I also need to do.]


Thanks in advance,

I think it is not a good idea to define classes in external methods. It is
better to define them somewhere in Shared (see the directory DC under
lib/python/Shared for example) and import them in your external method. 

import Shared.Tony.helper

 They can be very handy especially since python is way more elegant and
easy for complex logic in relation to DTML.

Not sure. need some more info. Did you try to use getattr to get to
object?


tmp=self.Actors.RENDER
renderer=getattr(tmp,template_id)

What kind of object is template_id?

People did report this bug elsewhere on the list. Apparently we're waiting
until monday when Jim Fulton can take a look at this. They're pretty sure
it's just a display problem and not something wrong with the object database,
but they want to make sure and check with Jim.

If you are sure that you can get along without the BASE HREF in a virtually
hosted (or other) Zope page, there is a way to fool the ZPublisher so it
doesn't include the obnoxious tag.  Just put

	<base dummy=dummy>

near the top of your method.  This turns out to be enough to fool the fairly
droidal scanning code into thinking that no additional BASE tag is needed.
Since it's an unknown attribute it should be a total no-op in browsers.  Of
course they could write a smarter parser in a future release so caveat
Zopor, but it works for now.  I wish they hadn't relied on that tag to begin
with.

Okay, never mind.  I figured it out.  I needed to use:

 expr="REQUEST.has_key('division')

to determine if the 'division' has been defined.

Also, the passing of multiple variables was obvious - just define a hidden
input field.

Thanks, anyway.

Message-ID: <007c01bf8553$1d6fa8e0$7b5addc7@laptop>

KM|Net News is a Zope through-the-web Product that allows you to post
news-style articles on your site. 1.1 is easier to install (because it
creates its own Catalog and does not have any external methods) and now
incorporates linking to external sites for more weblog-style publishing.
(KMNN is still different from Squishdot in that there are no discussions
attached to the articles and has different features for placement of the
articles within the article listings). You can see KMNN 1.1 in action at
http://www.byproducts.com

KMNN 1.1 also includes a new "contrib" method for trusted people to
contribute articles without review.

*** KMNN 1.1 requires PythonMethods. ***

You can get KMNN here:
http://www.zope.org/Members/tazzzzz/kmnn

If you're upgrading from an earlier KMNN, you may want to use the "Restore
Defaults" tab to "Rebuild Catalog" and restore "incoming.html". The new
incoming.html adds the fields for external articles.

This will probably be the last major revision of KMNN before the PTK.

Subject: [Zope] Logging users in Zope 2.x (second try)
Message-ID: <38C036C6.2300C61C@tm.ee>

How should I configure logging to get usernames into Z2.log

I first hoped to get it from Apache's access_log, but it saves 
username only when doing user authentication itself.

Then I thought that Zope at least would log it and migrated the 
site to Zope 2.1.3 to get logging support. 

Unfortunately it does still not log usernames and I have not 
found the place where I could turn it on.

Also the format is buggy:

Apache access_log:

193.40.215.135 - - [11/Feb/2000:08:29:55 +0200] "GET / HTTP/1.1" 200 2673

Zope Z2.log

127.0.0.1- - [11/Feb/2000:19:04:46 +0300] "GET /misc_/OFSP/dtmlmethod.gif" 200
1000

the bug being the missing space after the IP address.

what I was hoping for would have looked like:

127.0.0.1 - superuser [11/Feb/2000:19:04:46 +0300] "GET /manage" 200 1000

It looks like your dynamic linker cannot find your python libraries. 
There is an environment variable that you must set so that the linker
can find any libraries needed by shared library modules like
ExtensionClass.so.  I believe the env variable beings with LD_.  Do an
'env' (in bash at least) and look for something like that.  I never
remeber it cuz in Linux you just edit a file.

The binary will work fine with PCGI (Apache integration).  Whether it
runs on 2.5.x I don't know.

Hi Tres, Hi Jack,

Thanks for the infos/repost.
Is there no way to control UW IMAP to look for a specific folder in each
user's home dir for the INBOX root? Something like the way
http://host/~username/ mapping works in apache?

If not, then I'll add this instruction to the upcoming FAQ for
worldpilot, since this is the no.1 question up to now. (Jeeze, looks
like I'll have to install UW IMAP myself afterall, too.)

Cheers,
Ryan

In Amos Latteier's "creating XML Applications With Zope" at
http://www.xml.com/pub/1999/12/zope/index.html


There is an example that uses a Zcatalog.

He says to enter this into the expr field of the "Find Items to Zcatalog":

getNodeName()=='entry'


and click find.

When I do this with my own version, or even his version 
Zope gets this error:

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: Eval


it has to do with that entry in expr.

Is that a typo?

Sorry, coming in late here. The Env variable you need is LD_LIBRARY_PATH. Mine
is set to
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib:/usr/local/lib/mys
ql

(I know this 'cos I did a new Zope install the other day on an account that
only had 
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib
I started the Zope server under that account and found a broken MySQL product,
with an error message saying it couldn't load libmysqlclient.so.6. I had cold
chills going down my back for a looong few minutes....shudder)

Subject: [Zope] Assorted Zope problems
Message-ID: <20000303164457.A1221@velocity>

Hello-

I've been trying to get our existing Zope server (previously with ZServer
handling http) under Apache.  Here are some problems I ran into:

1. My biggest problem was that Zope uses the SCRIPT_NAME environment
   variable to construct it's notion of the base URI.  Unfortunately,
   SCRIPT_NAME gives the actual script name, not the URI.  So if you
   do a ScriptAlias, or any rewriting inside Apache, this isn't necessarily
   valid.

   An adequate solution seems to be to change
   PYTHONHOME/lib/python/ZPublisher/HTTPRequest.py line 211, to use
   DOCUMENT_URI instead of SCRIPT_NAME.

2. I couldn't get Apache with FastCGI and Zope working reliably.  On about
   1% of requests, garbage would be returned, resulting in random broken
   images or pages full of gibberish.  This is with the Oct 06 snapshot of
   FastCGI, compiled into Apache-1.3.12.

Anyone else seen anything like this?

Ed

Just curious, what does the result of a LIST with "~/Mail" look like on
UW IMAP?
What is the top node labeled as? 
I guess I could add a parameter to control the behaviour of the LIST
call.

"1%?  You were _lucky_!" (in my best Yorkshire accent).  I was getting
a much higher rate of errors (admittedly, I was only using the management
screen at the time as I was just starting out with Zope), but I ended up
switching to mod_pcgi2 to cure these problems.  The problem has been
mentioned before on the mailing list, but I'm not sure if a solution has
been found.

Platform is (for data point purposes): RedHat 6.1, Apache 1.3.9, Zope
2.1.4 and fastcgi Oct06 snapshot.

I want to write an object that can be traversed by ZPublisher.  The
goal is so I can write URLs like thingyForwarder/45/display, to get an
object corresponding to thingy #45, and call its display() method.

What's the Zope Zen way of doing this?  Implement an __of__ method for
acquisition?  Implement a __bobo_traverse__ method?  Make
thingyForwarder a Folderish object and implement all the folder
methods?

Subject: [Zope] Client-side Zope
Message-ID: <002501bf856e$7aee5640$770da8c0@bbs>

Continue to moving more job to the client, There will be more for Zope to
perform:

1. There will be necessary to generate various section-specific temporary
objects for CSS, DTD and Scripting files, framed or embeded html.

2. There will be necessary to support java or javascript access of zope in
the client.

In the first requirement, I would like to suggest an machenism to create an
section specific temporary object (which zope create the unique name and
substitute it) which dtml is able to write to it. The new object can be just
a new dtml-document. As in the following

<dtml-object dtdobject>
<dtml-object scriptobject>
<dtml-object cssobject>
<script lang="javascript" src="<dtml-var scriptobject>">
....

<dtml-write target=scriptobject>
function <dtml-var uniquevalidfunctionname>(){
   ....
}
</dtml-write>

I don't known about the solution of the second request.

In the long run, zope might encourage separate of control and data. The
current opening all tags in one dtml-method and closing them in another is
very dangerous if the control get complicated. I would like to suggest DC
consider a xslt like syntax which can also be used in server side xml to
html conversion if the client do not support it.

If zope is going seriously to the international market and xml, then unicode
is important in the core level.

I think __bobo_traverse__ will do what you want. You can look at the local file
system code in LocalFS.py as an example.

Nope, a bug.  The fix is in CVS but failed to make it into the 2.1.4
branch.

Put this line just after the license in
lib/python/Products/ZCatalog/ZCatalog.py

from DocumentTemplate.DT_Util import Eval, expr_globals

and it will work.

Take yer pick.

ZPublisher will try the following methods to traverse an object, in this
order:

__bobo_traverse__(request, name)

  Request is, suprise, the REQUEST object, and 'name' is the path
element ZPublisher is trying to traverse to.

getattr

  ZPublisher will try and get the subobject by 'name' with getattr.  If

One subtlety to be aware of is that __getitem__ seems to be called *after*
acquisition is given a crack for reasons that elude me. Since I've never been
able to get an explanation of how to use __getattr__ without blowing up the
acquisition machinery, this makes __bobo_traverse__ the only foolproof way that
I know of for hooking traversal. Someone please correct me if I am wrong.

The reason you have not heard of Dynamo is that Dynamo isn't being
hyped; Zope is.

There are other, non-Zope solutions out there, some of them quite solid.
I like to keep an open mind, and so should you. There are, indeed, quite
a number of people who have heard of Dynamo but never heard of Zope.

While my statistical data is entirely non-existent, I'll wager that
Dynamo-awareness exceeds Zope-awareness by a factor of at least two. ;-)
This isn't necessarily something to get upset about, and anyway I
believe, and hope, that the difference is shrinking.

Just a bit of background since you're accusing me of FUD.

Dynamo drives many of the web's most popular sites, and is in direct
competition with Zope, sharing the application server space with
contenders such as SilverStream, Sybase, Vignette, Jade, and many
others. Along with Vignette, Dynamo is one of the most successfully and
widely employed app servers solutions in existence. Whether this is a
good or a bad thing I'll leave for you to decide; I don't like Dynamo,
but I acknowledge its technical edge on Zope (and other solutions) in
several areas, such as clustering, reporting, personalization services,
e-commerce services, stability, and raw speed.

As an artifact of Dynamo's platform of choice -- Java -- there is
indirectly a "virtually limitless" expertise on Dynamo. If you know your
Java and your Enterprise JavaBeans, you already know Dynamo, and
stepping into your Dynamo shoes will be easy. Compare that to stepping
into Zope's multiple zens: acquisition, DTML, objects, Python. Note that
I'm not arguing against Zope here, which has a self-inflicted and
justified learning curve. However, managers will not necessarily respect
this difference in philosophy: The cost of training a person in the arts
of Zope will be measured against the cost of hiring an already-trained
Java wizzkid, and -- at least right now, today -- Zope will lose.

This situation has nothing to do with open vs. closed, either. Just like
Zope we're talking about proprietary (as opposed to standarized -- DTML
may be open, but it's still proprietary) technology. The fact that Java
is more widely established, and evolving faster, than Python is
unfortunate and outright infuriating, but right now that's how the cards
are dealt.

Dynamo also costs a lot of money. For small businesses, it costs too
much. A heavy-duty support contract with Digital Creations also costs a
lot of money, but you have a choice. On top of that, Dynamo is
open-ended but not open -- there is no source distribution.

My point? Zope already has a foothold in the small-time web site segment
of the market. However, big people wield big swords, and Zope, despite
its many powerful features, is not big enough for truly big things.

This is a two-part problem. The first part is that Zope's bullshit
factor is too low; it's not flashy enough to convince a senior manager
that Zope has enough clout for their business. It's a purely aesthetical
apprecation of Zope's poor-man, open-source philosophy, and the fact
that Zope does not offer a comprehensive monitoring system with a ticker
bar providing useless but impressive information does not fare well with
those who like to be bullshitted. We tech people know better, we know a
shiny surface tells us nothing about the engine underneath, but we tech
people are not holding the crucial component -- those big brown bags of
money.

Now, the second part of the problem is that underneath Zope's lacklustre
but entirely deceptive surface lies a powerful engine with scalability
problems. So far the only way to scale properly with Zope is a
combination of a load-balancing clustering system (eg., TurboLinux'
TurboCluster Server, which I can personally vouch for -- brilliant stuff
-- or Linux Virtual Server) with Digital Creations' ZEO, of which I've
only read about. There are Zope sites out there that are suffering
scalability problems (I won't mention specifics, other than that the
project I'm involved in is one of them). The problem is real, and
intrinsically related to Python. I wish I fix Python rather than sit
still and bitch about it; I periodically express my dissatisfaction with
Python's lack of performance, and I have certain ideas as to how to
improve it, but a research project like this would take time, of which I
can currently allot none. So instead I just bitch. ;-)

Finally, as for DTML being proprietary, Zope desperately needs native
support for XSL/XSLT as an alternative transformation language. I think
it was Michel who spoke vaguely of this being considered incorporated
into a future version of Zope. (At one point I planned doing an XSL
product, but I have not yet had a project to fund it with. So I'm not
just bitching here.) We also need better in-line scripting capabilities
than currently offered with External Methods and PythonMethods. This to
fight the creeping and ever-expanding notion that Java (replacing
Smalltalk) is the chosen, possibly even pre-destined, language for app
servers and middleware. Try to find an OODBMS, RDBMS, or application
server nowadays that does not use, or plan to use, Java as its
fundamental extension mechanism. I can think of a few, but they're few.
If you want to talk about FUD, you've got it right there.

Anyway, just my two cents.

Then please offer us an alternative, open, standarized interface to
monitoring data. The fact that SNMP in itself is insecure has little, if
anything, to do with whether Zope should be "polluted" with such
support.

An alternate route might be to have Zope export necessary variables
through a well-defined XML DTD, and then provide the necessary tools to
convert this XML output to SNMP, although supporting SNMP traps this way
would be difficult.

Perhaps supporting Performance Co-Pilot
(http://oss.sgi.com/projects/pcp/) would suit you better. Unfortunately,
PCP is probably not -- at least not now -- portable to Windows NT. In
fact, I'm not sure whether PCP will exist outside IRIX and Linux for
some time yet.

As far as pollution goes, assuming Zope exports the appropriate data --
in whatever form -- then support for performance/monitoring/management
APIs such as SNMP, PCP, WBEM, and to a lesser extent PDH, aren't
difficult to isolate into add-on products.

Thanks, Tony and Michel.  Unfortunately, LD_LIBRARY_PATH doesn't
seem to solve it, which is really puzzling.

The gory details are:

My base Zope installation is /usr/local/zope/Zope-2.1.4-src.  So,
ExtensionClass.so is in /usr/local/zope/Zope-2.1.4-src/lib/python.
My LD_LIBRARY_PATH is
/usr/local/zope/Zope-2.1.4-src/lib/python:/usr/local/lib:/usr/openwin/lib,
which ought to pick up ExtensionClass.so.

Anything else which would cause the import to fail?  I tried setting
PYTHONPATH too, in desperation, but it doesn't seem to make any difference.


Thanks,

Zach Frey


P.S.: I did try the binary distribution on Solaris 2.5.1, and can
report that it doesn't work.  Zope fails to start up with an unresolved
symbol error, so it really does require 2.6+.

If you consider separate code and data. If you think about putting
XMLDocument in real use.  This is one of the possibility:

using an xmleditor, the user can save the xmldocument to zope server as zope
automatically make all parts of the document reusable as zope object (is it
all what zope about? making a document into many small parts as each of them
be re-usable object?) This is process by zope automatically, the author do
not required to do extra works. The author can edit the document or part of
it and view the final result if the xml-editor support this.

To make this better, the author can embed dtml code in the xml document,
which make the document be active and live. You may have a system
automatically updated. Isnt it what zope designed to be?

The document inside zope can have multiple view as we can have dtml-methods
to transfer them into different view: html, xml+xsl+css, pdf, doc, etc...

If dtml syntax is not xml-complience, all of these will not happen.

A deeper change is to make dtml syntax more xsl like. I.e., make it block
oriented. So, the author is forced to code in good manner, instead of the
opening and closing tags were spearated into many places which I think is
very bad for maintenance.

I believe the problem is with ZServer/FCGIServer.py.  If you pull the latest
version from CVS (1.7), the problem should go away.  I had this problem a
LOT when I first started using it, but after getting the latest
FCGIServer.py (1.5.4.1 at the time), the problem went away completely.

Actually, what I am working on is abstracting that out. :)

What I _want_ to do, is to allow you to customize how you store the
dynamic data (like hits, clicks, remaing hits/click, etc.); whether it
be in an RDMS, Zope, File, whatever. I think I've got a pretty good
handle on it ... on paper (yes, I still do much of my code-writing on

I was thinking of an XML-RPC cronscript, though that wouldn't work on
windows boxes(?). Perhaps the recent Scheduler product will mature
enough, soon enough.

Subject: [Zope] PostgreSQL money weird problem
Message-ID: <38C06A0A.1DD2F6BF@uol.com.br>

Hi,

I'm with a weird problem with a report from a SQL database. I have a
field of type 'money', and every time I use it in a SELECT query, it
returns 0.00, doesn't matter the actual value of the field (in the
example bellow - the 'test' of the query -, the field Valor is of type
'money'):

 Id | Idcliente | Data       | Valor
  1 | 11        | 03-03-2000 | 0.0
  2 | 11        | 03-03-2000 | 0.0
  3 | 11        | 03-03-2000 | 0.0

SQL used:

select *
from compras
where idcliente=11

Running the same query on the interactive client, gives the value of
money:

credito=> select * from compras where idcliente=11;
id|idcliente|      data|valor   
--+---------+----------+--------
 1|       11|03-03-2000|R$50,00

 3|       11|03-03-2000|R$15,00 
(3 rows)

I'm using Zope 2.1.2, ZPyGreSQLDA, and PostgreSQL 6.4.2, running in a
Conectiva Linux 4.0 (kernel version is 2.2.5).

The definition of the class compras is:

Hi Ryan,

I thought I'd jump in on this since it gives me a good reason to learn a little
more about how IMAP works. ;-)

I logged in via telnet to my test system and determined (with some help
from the IMAP4 RFC) that the command being executed is 

LIST "" *

Since the UW IMAP server logs the user into their system account I can only
assume that this drops them into their home directory. If I execute the
requested command it will return nothing unless a Mail directory exists in the
users subdirectory. (I have one user setup this way from earlier tests and one
without the directory.) 

Executing the command LIST Mail * returns the same as LIST ~/Mail * for the
user with a Mail directory. 

I will attempt to do some checking on the functionality of the .imaprc file that
is sort of documented and see if this can be used to work past the problem.

Subject: [Zope] FYI: large files & linux.
Message-ID: <38C0AF01.C9887838@imeme.net>

Zopistas,

I was trying to get large file support on linux.  I succeeded, but only
partially.  Steps:

1. Download and install a kernel greater than 2.3.27. 
   It has the large file patch built in.

2. Reformat ext2 partition with 4k blocks:  
   mke2fs /dev/hdaX --block-size 4096
   the maximum filesize for ext2 depends 
   on the blocksize: with 4k blocks, it's 1TB.

3. Use Glibc 2.1.13-5 from debian potato.  
   unknown whether 2.1.12 from the gnu site is sufficient.

4. compile python 1.5.2 like so:
   CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" OPT="-O2 $CFLAGS"
\
 ./configure --with-threads

5. Now you can make files up to 4096 MB in size.  Why no bigger?
   I have no idea.  For me, at least, it means 1/2 as many zopes.

Optional step:

Wait.  In a few short months Linux should handle large files natively.

Ok, so you can't use the Zope distn that has a precompiled Python bundled (it
seems).

Try setting LD_LIBRARY_PATH as above and recompiling your Python source
distribution.

I know I had a real pain getting Zope-src distns running under Solaris (and
then found that our big expensive Sun Iron was half the speed - in pystones -
of my iMac! ...grrr) - but it can be done.

I would prefer this scheme too. You are breaking up a document into constituent
'blocks' in a different way than it is done presently.
I suspect you may get not only this but more in the future. There have been
similar thoughts going on in people's minds:

You'll have to call your DTML Method in a special way. When caling a DTML
object with <dtml-var name=DTMLMethodOrObject> this is automatically taken
care of. but when using it in the above way, you have to do this by hand:

  <dtml-in "creditCardSelections(_, _.None, *other arguments*)">

You now pass in the namespace as well, so your DTML knows how to access
other Zope Objects. This _will_ change in the future, BTW, this will be
automated for various reasons. You then won't have to think about all this
anymore.

Have alook at the following How-To, and espcecially the list referrenced at
the bottom of it:

They will introduce you to the more advanced ideas of DTML scripting.

I've just moved from qlcomm.com to the current location. Your DNS server
must still be using the cached entry. Should be fine in a little while.
You can mail me at jace@radiolink.net until then (the address I used to
subscribe to the list).

Here is what I use:


<dtml-var standard_html_header>

<dtml-with aq_parent>

<dtml-in "objectItems(['DTML Method'])" previous size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var previous-sequence-start-number>">
(Previous <dtml-var previous-sequence-size> results)</a>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" size=1 start=page>
     Document id: <dtml-var id>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" next size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var next-sequence-start-number>">
(Next  results)
</a>
</dtml-in>

</dtml-with>

<dtml-var standard_html_footer>

-----------
This doesn't work. When page=1, it's fine. When page >=1, dtml-in loops
all the way from "page" to the end of the list. I don't know why it's
doing that. The "dtml-in next" loop also does the same thing.

To explain the setup: I have a ZClass called "Article" based on
ObjectManager and set to accept only DTML Methods and Images. The above
code is in a DTML Method called "index_html" placed in the ArticleClass
(not when being implemented). I had the same annoying problem when
working with the results from an SQL query instead of objectItems. My
workaround then was to leave out the "size" parameter and instead use
dtml-if to compare sequence-index with page. It's ugly but usable when
there are only 4 or 5 pages.

I filed this in as a bug about an hour ago. Hope it gets resolved
quickly.

I've never used the DC Shared folder before. I've had a look in there as you
suggest and found some interesting things there. Time to read the docs on this
aspect I think...

Definitely. I'm now using the XXX PythonMethods that Evan Simpson contributed
and it's *definitely* helping to speed up development time.

Sorry, I should be more specific. The above code is in a method - def
supercascade(self, tag_id): which is called from Zope with a query_string,
tag_id=231441.

That code works, but I need to load up the renderers everytime supercascade is
called. I'm looking at the helper classes to see if I can't load up the
template_lookups array once. Having said that, supercascade isn't called
anywhere near the number of times that make_html (the method that generates
the HTML for display) is, so it's possible that I'm flogging a dead horse
here.

> tmp=self.Actors.RENDER
> renderer=getattr(tmp,template_id)
> 
> What kind of object is template_id?

It's a DTML document of the form (this example has id = lecture_info);
---
<hr>
<p class="<dtml-var class>"><dtml-var content null="&nbsp;"></p>
---

make_html then has a snippet in it so;
try:
    template_str = template_lookups[theclass]
    template = DocumentTemplate.HTML(template_str)
    theresult = template(self, content=content, src=src, thetag=thetag,
level=level, the
class=theclass, header=header)
    return "<!-- theclass [%s] thetag [%s]  -->" % (theclass, thetag)  +
theresult
except:
    pass

which will then render the HTML appropriately. The *really* neat thing is when
you have more complex DTML in the template that has ZSQL calls etc. 

It works well, but I want to speed it up a bit - it can take up to 6 seconds
to render a 100k document, and if I've understood my Zope architecture
correctly, thats one thread used up (and I'm only using the default thread
count - I think it's six) until the request has finished. I'm sure that
previous messages on the list have implied that it's not worth changing the
number of threads to something like 32-64, but I'm not sure.

That's my main problem, people are hitting the site and generating lots of
requests that are in the >1 second range. With our Apache servers, we just
spawn ludicrous numbers of httpd processes and don't worry about it. Zope is a
different kettle of fish and I need to think differently about it.

Many thanks for your help Pavlos, I feel things are a quite a bit clearer now.

Of course.  Some people suspected a "user error" at first, though. 
:-)

Anyway, I wasn't reporting a bug anymore,  I found the probable 
cause in the TimeStamp module, in the meantime, and reported 
that findings, and a way to fix it, here.

Lets hope for the best. :-)

PS: people have asked my for the modified TimeStamp module in 
(TimeStamp.pyd on my NT system) in private mail, but I'd prefer to 
have them wait for an "official" fix.  Poking around in the object data 
base source isn't something to take lightly.

   How many items are there in objectItems? May be you need orphan=0?

Subject: [Zope] Worldpilot/Python help
Message-ID: <003701bf85e2$693d6e80$6400a8c0@nc.rr.com>

I was very comfortable in my cozy PHP/MySQL world, until I saw Worldpilot.
I HAD to finally break down and
install Zope so I could have this.  Needless to say, my python/Zope skills
are a little lacking at this point.  I could
use some help.

Everything is installed and working great, except for a couple small
problems with Worldpilot.  I'll detail the most
significant first, and see how we do.

When I try to send mail, I get a Zope error with the following traceback:

<!--
Traceback (innermost last):

The problem is obviously (to me anyway) that the call to publish in the def
publish_module
(response = publish(request, module_name, after_list, debug=debug)) is only
getting one
argument instead of four.

I'm not sure I understand why, as this is a bit beyond my current
comprehension of python at the moment.
A gentle push in the right direction would be appreciated.

Thanks,

Hi all. I've read the Structured Text HOWTO but I'm still having trouble. 

I have a DTML Dccument, stx_about that looks something like:

I'm including that in another DTML Document, about, that looks like:

but the text isn't coming out formatted. What am I missing?
I've tried many different variants of formatting, with and without blank

I will have to concur that Philip's book is a very good read. In
addition to his book he has great suggestions for your library of other
books. There are many of his ideas I think are wonderful, however I do
have some philosophical disagreements on others.

Some of his views of computers and programming are somewhat cynical even
if based somewhat on fact.

His version of scalability of which he focuses on a lot is basically
throw lots of money at it.
Start off with a highly scalable, multi-threaded, high quality webserver
with an embedded scripting interpreter. In his case AOLserver with Tcl.
He openly hates Tcl, but doesn't work towards using the language he
likes where he works. Further more he thinks doing so is folly. (my
interpretation) He states relational dbms are the only way to store
data. Other technologies aren't as mature or capable. And on relational
dbs only Oracle is sufficient. With others you are taking unnecessary
risk.

So to scale with Philip you develop with AOLserver/Tcl/ACS, buy big,
expensive hardware, buy big expensive database. ie: throw lots of money.
Since he prefers everything to be in a single machine you can only scale
up processors so much before the $$$ start escalating. Price an 8
processor anything versus a Linux cluster of 8 machines.

This is not enabling for the little guy. Yes I know of the ACS port to
PostgreSQL. I think that's great. However it is going to be a step
behind ArsDigita/ACS because it does require porting to become
PostgreSQL able.

He has disparaging remarks about app servers, many of which are true.
However, I do not necessarily believe that learning Zope/webserver is
more difficult than learning AOLserver/ACS. And when you've got Zope
you've got Python instead of Tcl. For some of us, we like that. :)

As a prodigal son here, I embraced Bobo/Zope early, became concerned
about scalability, wandered the websphere, and have come back home. I
have looked at Java/Servlets/Enhydra, AOLserver/ACS, etc. I decided to
follow my heart. I like Python and Zope. I like the Python and Zope
communities. This is where I want to make a difference and contribute.

Zope can enable the idea person, the little guy with a twinkle in his
eye and a big dream to pursue.

Sure it may not "currently" scale as easily as AOLserver/ACS for big,
busy sites. However, I think it is being worked on. I think that there
are options within Zope, Digital Creations. To a very large extent
Philip solves scalability with $$$dollars.

With Zope you can still throw $$$dollars at Oracle. You can also throw
some at Sybase, or whateverBase you desire. If that gains you
scalability or the ability to sleep at night it's available. With
ArsDigita/ACS the only supported option is Oracle.

If I believed throwing $$$dollars to solve scalability was required. I
would much rather throw $$$dollars at Digital Creations. Instead of a
$20,000 to $500,000 on up license of Oracle which is per machine, per
website, and potentially expires. Instead of requiring buying big, big
hardware for $$$dollars. Throw the money towards Digital Creations or
other Zope or Python developers to solve the issues which hold
Zope/Python back. In the end you will have helped build a bigger, better
open source software solution.

As a little guy with ideas and dreams, this is my view. By the time a
website grows enough to run into scalability and performance problems
with Zope it could potentially be making enough $$$dollars to contribute
to solutions. Try that with AOLserver/ACS/Oracle, start with $$$dollars
and then hope for the best.

My other thoughts wandered into employment. When I master either Zope or
AOLserver/ACS, would I rather work for ArsDigita (yes, they pay well) or
Digital Creations, if an opportunity presented itself in the future. As
I know both are growing companies. I like Digital Creations. :) 

On a side note, on the AOLserver mail list there is effort to embed
Python and get Zope running on AOLserver. I think it would be great to
see Zope/Python being multi-thread, multi-processor able on a high
performance open source, multi-threaded webserver. It would be awesome
to have an embedded Python interpreter in AOLserver without a global
threadlock that worked with AOLserver's multi-threaded API running Zope.

On another side. A website I just learned about does a performance index
of many sites and gives a average amount of time to load pages. This
could put into perspective Zopes performance from the real world, from
your own website.

you need to put HTML comments at the beginning and end of your DTML
methods. These will be passed unchanged to the final page, and any
problems pointed out by your validator will be pinpointed.

The problem is a bit deeper than that. Even if a validator could be
convinced to ignore DTML, you would still have the problem of trying to
analyze an incomplete HTML document.

Message-ID: <000c01bf85fa$bfd07090$0201a8c0@iridium>

Hi,

This question may be very naive but is there any way to use Zope as a
mailing list manager?

The sort of thing I want to do is :

1. Check a mailbox for messages.
2. Grab any that are related to my Zope WebApplication
3. Process each message "request" depending on its content.
4. Send one or more email replies to one or more recipients (easy with what
is already in Zope).

This might allow me to create a simple list manager for instance or allow a
virtual mailbox for all my WebApp members.

I have not followed the discussions you're referring to, so this may be
old news to you, but one simple way to provide XML compliance without
screwing up the HTML is to require that the HTML -- or whatever you're
rendering -- must be properly UTF-8 encoded. This is probably the least
painful way of attaining XML compliance. 

Unfortunately, it *will* be painful unless you're also using an
XML-compliant editor. The low-level DTML source will end up looking a
bit like this:

  &lt;html&gt;
  &lt;head&gt;&lt;title&gt;<var name="title_or_id"/>&lt;/title&gt;
  &lt;/head&gt;
  [...]
  &lt;/html&gt;

The editor takes care of the en-/decoding of character entities.

An obvious alternative is to use XHTML and XML namespaces, which would
currently -- because clients aren't usually XHTML-aware -- incur
additional XHTML-to-HTML processing on the server side.

Just on a personal note: I _like_ the curtesy reply to my personal account.
I redirect mailinglists to their own folder. On a list like Zope, that is
very busy, I would very easily miss replies to my messages.

With a good filter (like I use), I get a personal reply into my In box, not

Subject: [Zope] setting a DTML method's namespace from a product method
Message-ID: <874sameir7.fsf@wiz.wiz>

I'm having some troubles with manipulating the namespace of DTML
methods that are called from methods of product instances.

Some questions:

- How do I provide a DTML method with a full acquisition namespace, as 
if it were called in DTML, when I call it from a product class method?

- Does a REQUEST.set(somevar, somevalue) operation add a variable to
the namespace, or does it re-initialize a new request? I can hardly
imagine the latter.

- Does the local scope of a class method in a product somehow
propagate itself to external DTML methods that are called from that
class method?

Context of my problem:

My product has the following class:

class NFGnav(
	OFS.SimpleItem.Item, 
	Persistent,
	Acquisition.Implicit,
	AccessControl.Role.RoleManager
	): 

which ultimately calls a DTML method:

	  return self.NFGnav_ActiveMapItem(REQUEST)

I can set arguments for the DTML method, no problem:
	  REQUEST.set('NFGnav_ItemTitle', object.title_or_id())
before calling the DTML method works just fine.

However, the DTML method seems to lose it's acquisition context in the 
process. That is, if I define an 'myimage' instance somewhere higher up in
the site hierarchy, I get KeyErrors if I try to call
	<dtml-var myimage>
from the DTML method.

Funny thing is, if I request the URL of the product instance with the
'myimage' appended, this seems to have no problem:
		  /mysite/somefolder/ProductInstance/myimage
returns the image, whereas
		/mysite/somefolder/ProductInstance/someMethod/myimage
gives a KeyError. So the aquisition context seems to be intact at the
product class level, but not at the product class method level. 

I took care to provide (PARENTS, REQUEST) parameters for every class
method invocation, by the way.

I'd appreciate any suggestions in tackling this problem. Is this
question more suited for the zope list or for the zope-dev list, by
the way?

Even simpler than buying new hardware, switch to a system like NetBSD or
FreeBSD that has supported large files for years and years :-)

I'm not sure if you considered this, but note that LD_LIBRARY_PATH needs
to point to *Python's* libraries, not Zopes.  It's not python that can't
find ExtensionClass.so, it's ExtensionClass.so that can't find the
standard Python library module.

Your message sort of implies that you were ensuring that
ExtensionClass.so was in the library path, but the problem (I think) is
that the Python libs are not in your path.

I could be wrong and this could be an entirely unrelated issue.  Can you
run python normally?  Import stuff like cPickle?

Welcome back, Jimmie. I enjoyed reading your analysis and agree with
the thrust of it.

One thing you express, and which seems to have ossified into the current
received wisdom, is that scalability will be improved  when some
mythical deep pockets consulting client pays to get it improved ; then
everyone else will benefit. The problem is with the leap of faith it
requires from the client.

I currently have several clients who are very interested in Zope.
Their web sites already receive megahits. They are willing to pay money
for consulting, but certainly won't bank their businesses on the chance
that a magic key to scalability is found. As a consequence, the
greatest commitment they will make is to install Zope on a Linux server
on a VPN and "see how it goes" in a toy setting.

Therefore, I can testify that right now, today, Zope is being hurt by
the lack of a story on scalability.

If economics or policy dictates that Zope requires an "Angel" to
bankroll scalability research, we all have to be prepared for a
scenario in which that Angel never appears. Personally, I don't like
taking such a passive approach.

Two clear impediments to Zope's wide acceptance have been frequently
discussed on this list -- documentation and performance.

The documentation "story" has travelled on an arc which might be
expressed like this:

* Zope is Open Source. The community should document.
* The community can't take on the deeper Zen issues
* Volunteers from the community are time constrained
* DC hires a technical writer
* The ZDP is formed
* ZDP suffers from the lack of time available to its volunteers
* DC commits Amos to attack the general documentation problem and to
evangelize documentation

Documentation currently seems headed on a good track. What have we
learned from this trajectory? We've all learned that the Zope experiment
is different from other Open Source projects. It *needs* the cooperation
of *both* the Zope community and Zope's authors "shooting at the same
basket" to solve this.

I believe scalability requires a similar coordinated attack and that it
can't wait to be bankrolled.

ZEO, although a bit of a black box to us at the moment, sounds, on
paper, like a logical and credible attack on one aspect of scalability
-- the "throw hardware at it" approach.

No doubt there are other hidden opportunities. What kinds of hidden
opportunities? Who knows; they're hidden. ;>) But can we bring them out
of hiding?

Some of them are simple applications of available compute science, yet
I don't see these codified or set down anywhere. Perhaps we should have
a single HOW-TO repository for techniques and metrics people have
discovered, or just happen to know, in the performance arena. This
would be a FAQ along the lines of "I want to build my Zope site for
best performance. What things should I do? What things should I avoid?"
God knows this question comes up often enough.

Then there's the design and makeup of the Zope software itself. Its
original design requirement probably didn't put scalability at the top
of the stack. Here, there are probably other areas where the user
community can't know enough about inner workings and overall design to
contribute effectively -- but which require attention and a commitment
from the folks at DC. I'll mention a couple of things that pop into my
head. These are simply conjectural -- dialog starters. I'll be happy to
be shown that I'm dead wrong about any of these conjectures.

Zope began as a brilliant notion, of Jim Fulton's devising. It began as
a fews lines of code and has evolved to include better than two
megabytes of code. DC has evolved from a company with one employee to a
company with maybe a dozen engineers contributing to the code
base and is looking to hire twenty more engineers.

Among this team of top notch talent, who takes ultimate responsibility
for evangelizing and improving performance? Who leads the effort at
code review, with an eye to marshalling refactoring efforts?

What would be an example? OK, Devil's Advocate: Here's one area of
concern I have, perhaps unfounded. Digital Creations utilizes Use Cases
as a tool for design, in the Ivor Jacobson tradition. Use Cases have
many proponents and some detractors. One detractor is Bertrand Meyer,
author of the classic _Object-Oriented Software Construction_. His beef
with the use of Use Cases is that it poses a fundamental risk: it
encourages a functional approach, based on processes (actions). He sees
this as the reverse of O-O decomposition, which focuses on data
abstraction. He believes it carries a risk of reverting, under the
heading of object-oriented development, to the traditional forms of
functional design, by considering what the system does, rather than
what it does it to. He believes that, due to this risk, Use Cases
should be confined to use as a validation tool, not a design tool, to
avoid closing interfaces prematurely.

So let's say that Use Cases is a useful tool, but one that has a subtle
built-in gotcha. What are the dangers? Naturally, one is negative
impact on code maintainability/reusability.

Another may arise due to the need to balance two competing technical
concerns: the desire to encapsulate abstractions, and the need to make
certain abstractions visible to other modules. With regard to the
dynamics of subprogram calls, the placement of declarations within
modules can greatly affect the locality of reference and thus the
paging behavior of a virtual memory system. Poor locality happens when
subprogram calls occur across segments and lead to cache misses and
page thrashing, which can ultimately slow down the whole system.

Is Zope prey to this? I don't have a clue. Does anyone? Like I say, I'd
be happy to be shown that this concern is unfounded. But this is the
sort of creeping problem which can enter into a growing code base like
Zope's, as it is worked on by numerous people, each devoted on one
module or interface. Combatting such problems probably requires having
someone (someone blessed with both Jim Fulton's dedication to O-O
principles and an unbending zealotry for absolute performance)
committed to periodically flying above the code at a sufficient
distance to see such patterns and making bombing runs against the
target problems. As busy as everyone at DC is, I'm not certain that
anyone is doing that at the moment.

Thanks for the replies!

I did get it to work.  Here is what i did:





I created a new python method inside my primary class:

    def is_local_name(self, name):
        """ returns true with ID if name is a local user
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rlist = filter(lambda x,p=self,s=thisdjname : p.data[x].name == s,
rlist)
        return rlist






then called it using this dtml:

<dtml-if namelist>
  <dtml-in namelist>
   <dtml-let thisname=sequence-item>
    <dtml-if "is_local_name(_['sequence-item'])">

I checked the WU IMAP mailing list, and found the following:

  http://www.washington.edu/imap/listarch/msg06947.html

In short, Mark Crispin (the author of WU IMAP) strongly recommends avoiding the
"*" wildcard altogether, using rather "%".  In this case, the '\NoSelect' flag
indicates (I think) that the item is a directory, and could be drilled into; 
or  perhaps the '\NoInferiors' says "this is a leaf -- don't descend" (my
ignorance of the IMAP protocol is showing).

I guess the idea here is to avoid using LIST once, but to do it "on demand" as
the user drills down the tree.  Mark also recommends using "LSUB" to pick up
"subscribed" mail folders.

Hope this helps!

Tres.

StructuredText expects list elements to be separate "paragraphs", where the
paragraph separator is an empty line.  Also, the indentation determines whether
the line before the list elements is treated as a header or as a paragraph.
Try::

 This is my document.
 
 - bullet1

 - Bullet2

which makes the preceding line a paragraph, or::

 Header Goes Here!
 
   - bullet1

   - Bullet2

Message-ID: <38C22166.EFC36537@aHIT.de>

Many thanks to Michael the author of TTImage
for pubishing your Product at zope.org.
You did a great job !

In order to create TTImage instances within DTML-Documents I made
some changes on TTImageClass_add because I got errors due to
empty BasicProps and DestinationURL.
Would be nice if you could include it in your next release.

I´m new with Python and especially with PIL so at the moment it´s 
not so easy for me to fix some further problems with the background
color.
When I set the backgroung color to 0xffffff the background color of the 
result is 0xfcfcfc ... seems to be an color palette problem ...   

Also I was wondering if it is possible to set the background to
transparent ?

I look forward to hearing your thoughts on my changes :-)

regards 
Andreas Heckel

Hi Matt!

I ran into this same problem. I finally traced it to a problem in the IMAP and
SMTP server options set in the setup screen. It seems to work best when these
are explicitly set to localhost and localhost. I'm not sure why but that's how
I got it to stop giving me that particular error. Unfortunately it will require
removing the current WorldPilot object and replacing it with a new one since
those parameters are not visible on the parameter tab of the object.

Good Luck!

Thanks, however I think they only work on date objects.

There is a DateTime() function to create date objects mentioned in the
DTML guide, but it doesn't seem to be documented.

Nevertheless, I would be interested in why atoi does not work for me.

Okay, it's simple enough - 

<dtml-call "REQUEST.set('mydate',_.DateTime('2000/12/31'))">

creates the date object I need to then reformat it.

Thanks,

It was never my intention to imply that throwing $$$dollars at DC was
required to improve scalability. What I said was based on perception of
such requirement. I'll admit "currently" Zope does not scale as well or
as elegantly as I would like. A statement I was making was that "if" I
(or anyone) "believed" that scalability == $$$dollars, I would rather
give to DC than Oracle. I believe Larry is doing all right on his own.
:)

I find Oracle pricing obscene. For the kind of $dollars it would take to
license Oracle I would rather see what DC could do with the additional
employees on beefing up Zope/ZODBs concurrency/scalabilities. There is a
thread on the WebDB forum about a group of people talking about putting
together a co-op to buy an Oracle license based on Oracles "unit"
pricing scheme for a moderately powered single processor Intel machine
it was going to run about $20,000. You would have to renegotiate if your
site got busy and you added a processor. Yuck!

I believe Zope's scalability issues will be solved over time regardless
of external $dollars. I believe more $dollars could speed up the
process, however it will still take some time. Currently ZEO is an
option but I don't know how well understood it is by the community.

Scalability Now can still be a sticky wicket.

Future things on Zope's side:
1. Moore's law.
2. Advances in Python and it's performance.
   a. Python becomes fully multi-threaded, multi-processorable.
   b. Stackless Python gets adopted and performance improves.
   c. Viper 
3. Advances in Zope, it's architecture and performance.
   a. Sam Rushing works miracles on Medusa/Zserver using Stackless
Python and Continuations.
   b. Zope does process pooling with each process on a different
processor. ZEO?
   c. ZODB does multiple data.fs's based on user design based on url
path directories
        allowing different Zope processes on different processors to
handle their respective dir.

It would be nice if some C/Python programming guru/genius would solve
Python's global threadlock issues where Python would scale on
multiprocessor machines. This would potentially render scalability a
moot point. The geniuses at AOLserver rewrote the threading of the
built-in Tcl interpreter so that it would be multi-threaded and work
properly with their nice multi-threaded webserver. Tcl's standard
threading I don't think (I could be wrong) is as nice as Python's.

If I had Oracle kind of money to throw around I would like to see
Python's thread issue resolved where Python becomes fully
multi-processorable. That would transparently scale Zope and benefit
other Python user's as well. It would enable Python/Zope to embed well
and play nice in multi-threaded webservers like AOLserver and others.
IIRC Apache 2.0 will be multi-threaded. If Python scaled on
multi-processors even a little guy could put together a dual-celery
machine a serve a nice site.

I agree wholeheartedly with you that there should be a concerted
coordinated effort between DC and the community to improve scalability
by allowing people to throw hardware at it. That was the primary issue
causing me to wander the websphere looking at options. I've learned some
things in the search, but I always looked back at Zope, even tho' my
wife liked Enhydra's logo, she thinks the otter is cute. Zope's current
logo is much nicer than the Purple and Gold. :)

If ZEO currently scales well, then DC needs some testimonials on their
website.

There definitely needs to be some documentation best ways to...
As you said, there is a consistent recurring thread of is ZServer alone
or ZServer behind Apache better.
Should I use a RDBMS or ZODB.
...

Some of us have no legacy issues. From scratch what's the best way to
design...

I agree the solving of Performance/Scalability and Documentation issues
would definitely help convert lookers into believers.

I am currently working my way through the docs and plan on helping
there.

While I was wandering, in my heart Zope was the project I wanted to see
succeed. I decided to put my mind where my heart was.  Possibly someday
some of my money too. :)

Some of your other concerns I can't address. However, one of the nice
things about Zope is that it is written in Python. Python imminently
supports playing and algorithm improvement. :)

Oops, spoke too soon.  Spent the last few hours trying to suss this out
without any progress :-(

I have a variable called START returned by a sqlquery

<dtml-call "REQUEST.set('startdate',START)">
start is <dtml-var startdate>

and that's okay

<dtml-call "REQUEST.set('month',_.DateTime(startdate).aMonth">

That, and variations of the same, dies with

Error Type: TypeError
Error Value: __div__ nor __rdiv__ defined for these operands

Why is that these simple little things are so difficult in Zope?

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

FreeBSD on intel architecture doesn't have the large file limit of Linux.

Not exactly true.  The *BSD's, like most of the rest of the world,
implement the basic POSIX file APIs which use a signed 32bit long
for file offsets in the base ABIs.  Ergo. if you are using the
equivalent of C's fseek(...SEEK_SET) (from beginning of file), you
are explicitly limited in the maximum size files you can process.

There are multiple hacked ways to work around this, one of which is
to allow offsets from SEEK_CUR to page-flip out into longer files
(just never use a SEEK_SET), or to implement another, parallel ABI
which takes a 63/64bit offset value.  Neither of which however helps 
the poor application which merely expected standards compliant
behaviour from its host and therefore didn't play by the local
"special rules",

Not completely correct.

man lseek... it doesn't work on file streams (fopen ), it works on 
file descriptors like poll and select,  and, it works on very very large files.

lseek is a POSIX interface, and has been a part of linux since at least 1995.
Indeed the BSD and Linux manpages are basically identical including this as 
a bug:

No, a Redirect is a client side thing. The response will tell your browser

You have to start up your Zope install in non-debug mode. By default, it is
started with the -D flag (see you start script). Remove that flag, and all
your tracebacks will be demoted to HTML comments.

Yup. Take a look at REQUEST.environ['HTTP_USER_AGENT'], which is also
accessible as:

  REQUEST.HTTP_USER_AGENT
  REQUEST['HTTP_USER_AGENT']

and in DTML also as

  HTTP_USER_AGENT

On Zope 2.1.4 (Win 32):
- I get "1900/02/28" when entering "2/28/00".
- I get "2000/02/28" when entering  "2/28/2000".

No errors. (I tested this on the Properties tab of a DTML Document).

The issue you report seems to be corrected in the last Zope subversion.


Cheers.

Hello Tim,


- To get the modify time for a file, use this code in a DTML document or 
method:

<dtml-with yourFileName>
   <dtml-var bobobase_modification_time>
</dtml-with>

or
<dtml-var "yourFileName.bobobase_modification_time()">

Hi !

I have added this as a FAQ to

As ZDP members you can become Maintainer of the question
and answer objects.

Greetings,

Maik Röder

   How do I use bobobase_modification_time on a file object ? 
                      
   To get the modify time for a file, use this code in a DTML
   document or method : 

   <dtml-with yourFileName>                                          
   <dtml-var bobobase_modification_time>                            
   </dtml-with>                                                           

   or 

   <dtml-var "yourFileName.bobobase_modification_time()">

   If your filename includes a dot, use instead: 

   <dtml-with "_['yourFileName.gif']">
     <dtml-var bobobase_modification_time>
   </dtml-with>

   or 

   <dtml-var "_['yourFileName.gif'].bobobase_modification_time()">

Message-ID: <14530.26613.662250.268116@loki.1012internet.at>

I want to do the following tasks

A user enters a list of products. Such a list is equivalent to
an order. Then i want the user to enter some things for each
product. I don't want to implement DTML pages for each
combination of products and i want to present one entry
screen for each order.

I tried the following approach:
I created a Folder named 'Products'. In this folder i
created subfolders named after the prducts code number,
e.g. `4007', `4008'., ....

In each of these folders i defined a DTML Method `New' which
hholds the DTML code to create an input form fr this product. My
plan is also to create methods named 'Display', 'Edit', .... so
i can render the objects in different ways.

In anotehr page i want to do something like:

<dtml-in products>
   <dtml-var "URL1 + '/Products/' + _['sequence-item'] + '/New'">
</dtml-in>


but this doesn't work. Nothing is displayed. I also tries
<dtml-var expr="...."> and <dtml-call "..."> (the last one
was pure desperation).


So what's the correct method for implementig such a system?

[many good points cut away]

| I don't like Dynamo, but I acknowledge its technical edge on Zope
| (and other solutions) in several areas, such as clustering,
| reporting, personalization services, e-commerce services, stability,
| and raw speed.

Not that I have very much to base a comparison on, but I regard Zope
as both stable and fairly speedy.  I think I can guess in what regards
an alternative could be faster, but I'd really appreciate to learn
where Zope lacks in stability.  Can you provide any references?

| -- DTML may be open, but it's still proprietary)

I don't quite grok what "the situation" is referring to, but I think
you're wrong here, or at least mistaken regarding the meaning of
"proprietary".  Proprietary, according to Merriam-Webster, means this:

[cut from Merriam-Webster]
Function: adjective
Etymology: Late Latin proprietarius, from Latin proprietas property --
           more at PROPERTY

    <a proprietary process>
3 : privately owned and managed and run as a profit-making
    organization  <a proprietary clinic> 
[/]

|

| factor is too low; 
[...]
| We tech people know better, we know a shiny surface tells us nothing
| about the engine underneath, but we tech people are not holding the
| crucial component -- those big brown bags of money.

I'm not sure if I agree it's a problem, then, that Zope lacks in the
big-department. :-)

| [under Zope's surface] lies a powerful engine with scalability
| problems.

What part of Zope's engine are you referring to here?  Do you mean
Python in general, are some specific part?  Like ZODB?

| So far the only way to scale properly with Zope is a combination of
| a load-balancing clustering system (eg., TurboLinux' TurboCluster
| Server, which I can personally vouch for -- brilliant stuff -- or
| Linux Virtual Server) with Digital Creations' ZEO, of which I've
| only read about.

I actually thought of ZEO as a very nice way to scale Zope.

| There are Zope sites out there that are suffering scalability
| problems (I won't mention specifics, other than that the project I'm

It would be very much appreciated if you could share some specifics.

[...]

I second that.

| -- in whatever form -- then support for
| performance/monitoring/management APIs such as SNMP, PCP, WBEM, and
| to a lesser extent PDH, aren't difficult to isolate into add-on

You are right about that, and I think that's a better way to provide
such support, rather then building specific support for any of them
into Zope.

2. what's wrong if there is no table-update after

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

A more zopish would be: define your 'New', 'Display' and 'Edit' methods
in the Products folder and use properties in the subfolders for the
different rendering. For example:

give each subfolder a property 'Description', and a property 'Price', in
your Display method put something like:

Description: <dtml-var Description><br>
Costs: <dtml-var Price>

So, with an url http://yourhost/Products/4007/Display

Display is rendered in the context of the object '4007' and its
properties will be used.

This is a bit unclear. Where do you call it (note that Zope doesn't know
'pages', it only knows objects, which define what's going on) and where
does the 'products' come from? I assume you want something like this:

<dtml-in "objectValues(['Folder'])"> 
   <dtml-var absolute_url>/New <dtml-var title_or_id><br>
</dtml-in>

objectValues(['Folder']) gives a list of all (sub)folders of the current
object. Note, that if you put this into a DTML Document, the list will
be empty, because a DTML Document is an object by itself, which has no
folders associated with. You'll need in an DTML Document a <dtml-with
"PARENTS[0]">, this will include the namespace of the folder object,
where the DTML Document is called from.

For each found item <dtml-var absolute_url> displays the absolute url

Generally, this sounds like a typical ZClass task. Have a look into the
ZClass tutorial and into the example products (there is one called the
boring product on Zope.org) for more informations.

Is START being returned as a string, or as a DateTime from your query? If
it's being returned as a string, you need:

  <dtml-call "REQUEST.set('startdate', _.DateTime(START))">

aMonth() is a method, not an attribute. You need to _call_ it, i.e.:

  <dtml-call "REQUEST.set('month', _.DateTime(startdate).aMonth())">

or, if startdate is already a DateTime:

  <dtml-call "REQUEST.set('month', startdate.aMonth())">

Another way of doing this, however, is something like the following:

  <dtml-call "REQUEST.set('mydate', _.DateTime('2000/12/31'))">
  <dtml-var mydate fmt=dd>-<dtml-var mydate fmt=aMonth>-<dtml-var mydate
fmt=year>

Voila.

The above does not seem too difficult to me. You made a few simple
mistakes, that's all.

I forgot that you can also use C-style formatting, which reads much better
in this case:

  <dtml-var mydate fmt="%d-%b-%Y">

Try (untested):

  <dtml-in expr="Products.objectValues()">
    <dtml-var expr="_['sequence-item'].New(_.None, _)">
  </dtml-in>

I would investigate ZClasses. It seems to me like you could end up with a
"Product" ZClass (though I might call it something else to avoid confusion
with Zope Products), which contains your New, Edit, and Display methods.

Depending on how much each Product differs, you might have a
WidgetProduct, ThingamabobProduct, DoohickeyProduct, etc. Or, maybe you
can just get away with Product. I'd have to know more specifics to get
into detail.

I'm a relative beginner to Zope, so I'm not sure what I'm talking
about <grin>, but it seems to me from my limited experience that
you can't call out an object using a URL in a dtml-var.  Instead
you need an object reference.  So try something along these
lines (this is untested because I'm in the middle of my own
debugging mess):

<dtml-in products>
  <dtml-var "Products.get_item(_['sequence-item'],0).New"
</dtml-in>

I'm sure the above is not right from a Zope standpoint, and
the Python is probably wrong too, but maybe it will send you in
in the right direction.  What I'm aming for with that psuedo code
is to get the property of Products whose name is in sequence-item,
without rendering it (that's the ',0' bit), and to pick up
*its* 'New' property and render that.  Maybe a real Zope expert
can correct my code.

Or more likely, as others have suggested, using a ZClass is the
right direction anyway, which would avoid the whole syntax issue
<grin>.

It works as written

<dtml-call "REQUEST.set('month',_.DateTime(startdate).aMonth">

Subject: [Zope] More search engine woes
Message-ID: <E12RiXK-0007iL-00@ethereal>

I'm not sure if this is a PTK-specific issue, but I'm starting to
believe that it isn't. So I thought I'd post here with my problem and
see if someone could possibly point me in the right direction. I also
unsubscribed from the list recently, so please CC me with any replies.

I'm using Zope on a student organization website which I am
developing. Ideally I'd like for this to be an extremely popular
community-driven site, so a working search engine would be a
necessity. Additionally, I'd like to exclude unapproved items from
searches so that only moderated content is placed in the queue of news
items and ad banners which are being indexed. I'm also writing
site-specific documentation which is intended to guide members through
the process of creating news items, ad banners, etc., and I'd very
much like to have this content indexed as well.

Today I noticed that my search engine failed to produce any
results. Searching for the letter 'e' didn't even reveal anything,
which is unusual since E is the most common letter in the English
language AFAIK. So I tried digging into the ZCatalog documentation,
and poking around in the interface has confused me.

I created a help folder, and added an advertising document which
briefly explains how to create news items and such. Yet, I can't seem
to get this item to appear in the ZCatalog. In fact, the only item
which does appear is /Members/nolan, my PTK account page. Clicking on
the "find" tab and checking the "all items" checkbox seems to imply
that all items of every type on my site will be cataloged, but doing
this always results in only one page being listed in the catalog. Is
there some reason why the contents of help/ aren't being listed?

Thanks a bunch. If I can provide any additional information then I
will be glad to do so.

Ran into this one myself - the solution is to remove the DocumentRoot
directive, then just use the SetHandler and similar tags in the body
of the config file, though you can put them in a location container if 
you like.

Subject: [Zope] Setting attribute from DTML method in ZClass
Message-ID: <20000305223451.A15162@mimar.demon.nl>

Hi,

I've created a ZClass with a method 'force_update'. When a user is viewing
an object, there is a formbutton which they can press and force_update is
then called. So far it works. What I want my force_update to do, is that
it should set the needs_check (type boolean) in the object to true.
With <dtml-if needs_check> I print different things depending on whether
the object needs a check. From the Property sheet I can change the
settings. 

So, how do I put something like this().needs_check = 1 in a dtml-method?

Greetings,
    Chris Niekel

Subject: [Zope] zclass instance "broken" on copy/paste?
Message-ID: <010301bf86f3$d507db20$c3f28ec6@hikari.anu.edu.au>

I have a ZClass (Shot) which is nested beneath
a container ZClass (Storyboard).  I.e., an
instance of Storyboard might be:

Scene1 (Storyboard)
 - shot1 (Shot)
 - shot2 (Shot)
 - shot3 (Shot) ...

For reasons that I cannot discern, copying and pasting 
instances of Shot does not work.  I can copy them, but 
pasting creates a broken object:

  "This object is broken because the unknown product that 
   created it is no longer installed or is installed 
   incorrectly."

I suspect the copy has in fact worked because the title
in brackets is that of the source object.  This is an 
isolated problem on my site.  All other nested Zclasses 
work fine but I cannot pin down the difference.  This is 
Zope 2.1.4.

Has anyone else encountered this problem?

Darran.

Subject: [Zope] Simple Z Search Question - lost something while renaming
Message-ID: <000601bf86f4$06c5c5f0$0100a8c0@pinol1.sfba.home.com>

I'm trying to determine what might have failed in a Z Search generated set
of objects.

I used the Z Search wizard to create the search interface and tabular
report. They ran fine. I then renamed the data source (odbc) and both the Z
Search generated objects. I made sure that the input form reflected the new
report name. Now the input form will come up but when attempting to search I
get a "Object Doesn't Exist" type error.

I've also recreated the tabular report and it's input form with the Z Search
interface, and of course they work. I think the problem is with the report
as the original input form will sucessfully populate the recreated report.
What's interesting is that a compare of the text in the original vs the new
Z Search created report object show that they contain identical text.

I've also used Z Search to creat a similar "record" format pair of objects
that seem to endure any number of renamings, which is puzzling too.

I think that there are some variables hidden away, properties, whatever,
that I can't get to. This is probably pretty transparent to everyone, but
it's a bit of a stumper for me. In general this is a useful experiment as
it's obviously very important to know what effect name changes will have.
The docs state something to the effect that it's not too wise to change
names, but I've also seen that some name changes are propagated. So it would
be great to know what the pattern is. Maybe it's as simple as "rename at
your own risk".

hi all,

i installed fastcgi on my server and added -appconntimeout 0 (as suggested by
ppetru).  tried both unix and tcp socket.  however, i can't get 100%
availability.  there still exist connection failed (connection refused) errors
and incomplete headers 0 errors.

my config
rhl 6.1, pIII 500M, 776M RAM, oct6 fastcgi snapshot, FCGIServer.py from cvs ver
1.7, zope 2.1.3

i glanced at FCGIServer.py.  there were references of max connection (10) and
max request(50).  will this have any bearing on the connection refused error?

do i need to d/l other files instead of only FCGIServer.py?
i am also considering mod_pcgi2.  can anybody with fastcgi and mod_pcgi2
experience enlighten me?

This how-to will give you all the details:
http://www.zope.org/Members/lstaffor/zProperties

The short of it is that you need to call manage_changeProperties for the
propertysheet in question (which is actually what you need to do in Python
as well).

<dtml-call
"propertysheets.YourPropSheet.manage_changeProperties({'needs_check' : 1})">

It is very stable, indeed, so I take that back. ;-)

There are cases where I have been forced to kill Zope processes that
have falled into some sort of coma, but I've written these off as
growing pains in an evolving product. ;-) To date, Zope's stability
problems seem to have been mostly related to fragile database drivers.

I was really thinking of something else, and should have used another
phrase -- something like "high availability". Again, I have only read
the marketing material on ZEO, the product that supposedly provides such
features (load balancing, replication). Assuming ZEO works, strike that
from my list.

What I've observed is that I'm running Zope on Linux and accessing it from
a browser on a Windows box. I can create empty File objects and file
objects containing _text_ files without a problem, but as soon as I try and
include or upload an _.exe_ file it barfs with the commit_sub error.
I'm wondering whether there's something occuring inside the .exe file
that's playing up with the storage mechanism, maybe some kind of terminator
or something...

(I tried uploading files from Solaris and uploaded text files from there
fine, so I was thinking it was a windows problem, but upon trying them text
files worked under windows as well. It definitely seems to be an exe
problem instead.)

I mean proprietary as being controlled by a private party -- owned, in a
very liberal sense -- as opposed to being standarized. XML is not
proprietary. DTML and Java are.

I'm not as knowledge about IP laws as I would like to be, so I can't
really defend my use of this word or whether DTML is an intellectual
property of Digital Creations. Perhaps somebody else more suited to the
task could clarify.

If the suits in managements (assuming you work in such a place) tell you
to go learn Dynamo because that's what they want to use, wouldn't you
say it's a problem?

I definitely believe that Python is Zope's largest problem right now.
It's also, from a technical point of view, one of it's biggest assets --
Zope is becoming the killer application of Python, and might eventually
become the driving force to evolve Python, which is, I believe,
suffering from draught into the contributor department. Skilled
developers aren't flocking to Python to make it faster. Not right now,
anyway.

My hope is that Zope will change this, because Python has possibly one
of the slowest interpreters on earth. Python zealots -- and there is
such a beast -- will tell you that Python's performance is less of a
matter because what you sacrifice in speed you gain in power, ie.
computational expressiveness through a high-level, dynamic language.

For an example of a good, Python-like, dynamic language that is also
very fast, take a look at Dylan. In current implementations, Dylan is
not interpreted but rather compiled to native code, but in theory there
is nothing stopping anyone from writing a highly efficient Dylan
interpreter. Dylan's magic comes from its use of type hints, a system
which I had recognized as likely pivotal to improving Python's
interpreter long before I knew of Dylan. In Dylan, specifying a
variable's type is optional. When omitted, the Dylan compiler will
usually be able to infer the type from what you do with the variable
(ie., it sees you're assigning an integer to it; hence it can assume
that, for at least a stretch of execution, the variable remains an
integer). When you explicitly declare a variable's type, Dylan applies
the necessary code optimizations (such as using tight integer maths or
string copying) as well as static type checking. In Python, variables
can hold virtually anything, and this incurs a huge amount of checks.

Just imagine -- while Zope is running, thousands and thousands of the
same little checks are performed continuously, over and over again,
amounting to no uncertain overhead.

Python's biggest overhead comes from its dynamism -- the dynamic typing,
as explained, combined the object allocation system: most things is an
object, so a lot of objects are constantly spawned and torn down, often
in rapid succession because the compiler/interpreter can make few hard
analyses of when stuff is needed. Python also has a high function-call
overhead.

No. Ask around, do some research. Ask Digital Creations -- they probably
know of a few, although I'm guessing that they might feel it would hurt
their reputation to tell. Many companies using Zope might not want to
tell you because it would hurt their position, especially if they're
public companies.

Here's one specific case that I'm personally struggling with. I have a
page that returns a large number of dynamic database results in a
relatively simple table. The results are first munged by a small Python
script. This stuff is slow. Internally, as far as I can determine
(through shallow study of the database code), Zope allocates a row
object for every row you access -- even if the row has been returned
earlier on. Zope has a 1-row cache for cases when you repeatedly ask for
the same row in succession. Zope also has a row cache that is useful for
static result sets. Yet, for dynamic result sets, the processing
overhead is huge. The overhead isn't so higher than any other overhead
in other areas in Zope, but it's especially painful here, because it
affects the generation time of a single page, whereas other kinds of
overhead are more evenly distributed across multiple pages and multiple
users.

Exactly. However, the necessary counters must be built into Zope at some
point, and exposed through a common (XML? Python/XML-RPC?) API. Then we
could attach publishers for SNMP, HTML, XML, whatever.

Which reminds me. Does Zope have a mechanism for extending the
Control_Panel namespace other than through the Product sub-folder? I'm
too lazy to check, and I don't remember if this was ever discussed.

I need record level locking in a database, and I need it quickly, without having

and refuse to use any MS products, so don't go there.  Additionally, I need to
be able to easily export database content as both SQL statements and in some
sort of delimited text file format.  I can do the latter with Zope, of course,
but it is fairly slow and expensive.  MySQL does all of that nicely, but doesn't
have record level locking.  Please respond to me as well as the list.

Subject: [Zope] Zope Documentation Project (ZDP) Announcement
Message-ID: <38C31F68.123691B3@berg.net>

Dear Zopistas,


The Zope Documentation Project is pleased to announce the availability of
the new zdp.zope.org website, which aims to give the Zope community
an additional place for sharing knowledge, and for working together
on providing good Zope documentation. The new ZDP homepage already contains
many useful resources for the Zope community, which for the most part
complement the already existing types of documentation available on zope.org. 

We sincerely hope that Digital Creations will play an active role in
the Zope Documentation Project and help merging the existing Zope documentation
with the documentation provided via ZDP. To see what Digital Creation's Plans
for Zope Documentation are, have a look at:
http://www.zope.org/Members/Amos/Documentation/Plan

When we built the new ZDP site, great emphasis was placed on providing
ways to easily get aware of what is new on the site and to quickly get
an overview of what pieces of documentation need Maintainers, Writers,
Commenters and Reviewers. Thereby contributors are directed to the
documents and projects that need help. Everyone can contribute according
to their interest and level of experience.

We invite you to join the ZDP and to help building up a great
knowledge base on Zope. This also includes helping to customize and 
extend the ZDP-Tools, which is the software with which the ZDP site
was built and on which it runs. The ZDP-Tools are being developed 
on-site, and are completely written in DTML to allow for rapid 
through-the-web programming. Questions on the ZDP tools can either 
be directed to the ZDP mailing list or to me, as I am the ZDP-Tools
maintainer (Maik Röder, roeder@berg.net).

The most important sub-projects of the Zope Documentation Project are:

1. ZBook

   In this project, we are collaboratively writing a book about Zope.
   There are already many chapters, most of which are still drafts.
   We need feedback on these drafts, so maybe you can give some 
   comments directly on the drafts, or discuss them on the ZDP mailing
   list or directly with the author. The ZBook project is maintained 
   by Tom Deprez (tom.deprez@uz.kuleuven.ac.be). 

2. ZFAQ

   This project tries to answer the frequently asked questions on Zope.
   The project is in need of additional contributors, so if you
   have a  question on Zope, or an answer to share, then you are
   welcome to add it to the ZFAQ. If you want to help moving the old
   Zope FAQ  to the new one, then just contact Kamon Ayeva
   (kamon.ayeva@bureauveritas.com), the maintainer of the ZFAQ project.

3. ZSnippets

   Snippets are short pieces of DTML or Python code which come with a
   description of their purpose and how they work. This project is
   maintained by Rik Hoekstra (rik.hoekstra@inghist.nl), who will get
   an automatic email notification when you add a Snippet, so you are
   invited to help flooding his inbox ;-)

To become a ZDP member, write an email to the ZDP mailing list (zdp@zope.org),
and we will create an account for you. For the time being, this will give
you Manager rights on zdp.zope.org. Once we use a tool like the forthcoming
PTK Login Manager for automatically adding new members, we will have to
give more restricted access rights.

Thanks go out to Digital Creations for sponsoring the ZDP server at Codeit
Computing (http://www.codeit.com), a Zope Hosting Provider which is
kindly giving the ZDP project commercial support for an Advanced Zope
Hosting Server !

The ZDP site has not been tested under heavy load, so just in case 
you should experience down times, please report to the ZDP mailing list
at zdp@zope.org, and come back later. If you should not be able to 
reach this site under the name zdp.zope.org, try using the IP address
209.185.210.24 in the meantime.


So, you are invited to visit us at:

http://zdp.zope.org


Best Regards,

Maik Röder

Subject: [Zope] AS400, DB2 and Zope
Message-ID: <20000306032022.4041.qmail@www.eventera.com>

I am putting together a proposal for a steel, cooper and plastics
manufacturer based out of Germany, but with a large IT shop in 
Detroit. They are looking at Uniface Web Application Server, from 
Compuware, to do their web work. Although they approached me for 
my Uniface expertise, they seem open minded toward Zope. This is
their first experience building an application on the internet. 

Thier data is stored in a DB2 database on an AS400. While I have
used DB2, that has only been on MVS (don't the call it OS/390 now?,
am I dating myself?), and I was never the DBA. They seem to be
open minded about the operating system for deploying the web
application server, but I suspect that they will want to use
Solaris. I gues I am nervous because I don't know what I need
to know, and I don't have a AS400 laying around to play with.

Is ODBC an option for talking to DB2 on an AS400 from a Solaris 
box running Zope? How about from a linux box running Zope? Has
anyone heard the news on the OCI-based driver that DC promised
"real soon now" at the IPC8? Does anyone have that working?

I am going to pitch Zope and this project proposal on March 17.
There is a lot of money on the line, I appreciate any assitance and
my memory is long. If appropriate, please resond to me in private.

Greetings,


Look, I don't want to start any holy wars, just to get a head count, more or

Until now, I've been using Netscape, whilst desperately searching for some
replacement that didn't haemorhage memory.  I think I've even managed to narrow
down which part of NS is losing the memory (it's the edit box, which is why it
seems to happen quicker when working with ZOPE).

However, in my searches I've yet to find ANYTHING under Linux that comes close
to the functionality of NS.

As I said... I don't want advocacy here, simply name and version, and perhaps
a quick rundown of the reason(s) you chose it over others.

I am on windows and use IE 5.  However, when NS 6 (mozilla) comes out I am

Yep. In fact it goes quite a bit further:

It uses a BSD license so it's even more libre/lucre free than MySQL.

Er... do you mean ' I need to be able to easily export database

Or transactions, or constraits beyond NOT NULL and UNIQUE, or triggers 
or rules, or arrays or a dozen other things you'll wonder how you ever 
did without when you where using MySQL :-)

I'm running pretty much the same thing except for Zope 2.1.4.  I haven't had
any of the problems you describe.  I don't know if FastCGI changed from
2.1.3 or not, and I've only been using tcp socket.  I know this doesn't
really help solve your problem, but it does indicate that your setup

Subject: [Zope] beginner's question: references
Message-ID: <38C34B36.596AF966@primenet.com>

This is such a stupid question, but I can't seem to figure it out from
the docs.  How do I make an object in Zope reference another object?  I
don't mean containing like a folder, I mean one object referencing
another in a different part of the hierarchy.  For example, if I make a
class to represent movies, and another to represent theaters and I want
the movies to reference the theaters they're playing at and vice versa. 
How does Zope handle this?

Please try to frame an answer in the context of ZClasses, since that's
what I'm using.  (Or tell me if ZClasses can't do this yet.)

Thanks,
Perrin

Hi,

Problem:
    I have two web servers on one machine.  The first uses the standard
    port (80) the second (Zserver) uses port 8080.  How can I point
    to a page on the first server from the second?

Given:
    hostname:  monica.usc.edu

I've tried:  href="//monica.usc.edu:80/...

Results:
    * The page delivered to the browser has the site name including
      the ":80" stripped off.
    * Any foreign site name is NOT stripped off.

Well, you see... here's my problem.  I am using NS 4.7 on Linux.  And it chews
up memory like it's going out of style.  If I don't keep an eye on it, I wind
up in a swap-frenzy, and having to wait up to 5 minutes for response to any
keystroke (always the "KILL THE DAMN APP" keystroke :)

As for IE, i've had no 'back' problems with it when i do work from home (that
box is mostly for playing, so why not have a toy OS ? :)

Help,

perhaps somebody from DC can help me swiftly?

Is it possible to use your own manage_afterAdd method in a ZClass which is
a descendant of CatalogAware Class? If so, how can you get this done?

Does there exist something like 'inherited manage_afterAdd', like in other
Object languages (eg Delphi?) : eg:

def manage_afterAdd ....
  <blablabla my stuff blabla>
  inherited (and does now performs the method from the parent class)


this doesn't seem to work :

def manage_afterAdd ...
  <my stuff>
  catalogAware.manage_afterAdd ... 

Help! Thanks in advance!

Tom.

Subject: [Zope] A zope fear...
Message-ID: <20000306033837.A12534@devware.com>

Several times I have heard folks mention a fear of "not being able to
get my files OUT of zope once they are in there." And usually the
answer is "Well just back up your Data.fs file and don't worry about
it."  I think perhaps this answer doesn't actually address the root
concern.  I think the root concern is one that I am actually coming up
against right now in debates about using Zope for a project.  That is,
if I stick with scripting languages or other traditional languages, if
I need to, I can always fall back on text processing tools to make
large global changes to my projects.  How can I do this with zope?
Many of us programmers are taught to learn to manipulate text like
magic.  Zope seems to take that power away from us.

So, the real heart of my question here is: I just spent 3 months
building a web site using Zope.  Suddenly, we decide to change our
database schema, and I now have to go through and change all 400 of my
SQL methods in zope.  How can I automate this process?  How can I do
this just like a good-ole multi file search and replace?

Answers that don't count are: Use the find mechanism built into
zope. - It's not powerful enough for this.

Another: Your design shouldn't have relied on something that would
change. - Well, it happens, now how do I fix it?

A secondary question here is, what about "software configuration
management" and zope?  What if I need to return to an exact version of
my web site for testing a certain bug that's now cropped up at a
customer site.  What's the easiest way to automate keeping old
versions around without having to roll back my current changes.  That
is, without using the built in versioning?  (Sorry, CVS *is* more
powerful in some cases)

Message-ID: <Pine.GS4.4.21.0003051530570.6405-100000@jeeves.stud.ntnu.no>

Zopistas,

I have a small problem here regarding uploading of files. We're setting up
a site where people can upload their MP3 files. We've tested everything on
our site, and everything seemed to work fine - until people started
uploading with modems.

They get timeouts, server not found etc. after around 5 minutes of
uploading. First we thought that it might be because of our proxy setup
with apache or - less likely - the external python method that handles
the file, but when I dug out my old 14.4Kbps modem and tried uploading
a 4MB file directly into Zope at port 9090, I got the same errors.

Is there any kind of timeout settings in the ZServer I can tweak?
Or is there something else going on?

Please help! This is very frustrating, as 90% of our users are modem
users...

Thanks in advance,


Alexander Limi
http://mp3.no


For reference, our setup is as follows:

We run an apache server which forwards all requests to mp3.no:80 to
login.mp3.no:9090. In other words, we use apache as a proxy for the
ZServer. When we try to upload a file from our own computers (10Mbit
network connection), all is fine and dandy. But when modem users try, or
if we try with extraordinarily large files, we get the following error:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST
/artists/testartist/testtrack/add_mp3.
Reason: Error sending from remote server.
Apache/1.3.9 Server at mp3.no port 80

Well I am not a Zopeguru by far, so the only idea I have is that in the
worst case you can always use ftp to such the stuff out of zope, then edit
it, then push it back into zope with ftp.

Well this is really something ftp should work for; making backups. ;)

NS (4.72) goes up to I guess 40 MB or so in worst case here. Just restart
it every day and it should be fine. Also, RAM is cheap (ok not as cheap as
it used to be a year ago, but anyway), so make sure you have 128 MB of ram
or more in your machine.

Mozilla is way cool, but it's still alpha so use at your own risk. I found
it is almost, but not quite, ready for real use.

Hello, 

we have some strange problems with the "SiteAccess"-Product. We are
building up three web-applications on one Zope-Server and three different
domains. Everything works fine with the "Site-Access" but if you have more
than 5 requests at one of the sites the speed gets very slow and you have
to wait about 3-5 and more seconds to get back a simple dtml-document.

We made some tests with the __no_before_traverse__ in the url and found
that there isn't that speed-problem if we access the documents direct
without use of the virtual-hosting.

Has anybody the same problem or an idea how to solve this ?

on win2k i used to use InternetExplorer 5 , but it is
incredibly annoying when the backspace-key is also the hotkey for
'back'; i guess you can see what problems might arise
from this when you accidentally unselect the textfieds when
deleting text, and press backspace a couple of times and end
up 3 pages back in history..

I have found Opera 3.6 to be by far the best browser for
zope-management. It is quick, lightweight, and usable with
full keyboard-access, but it costs money, and allegedly the
linux-version stinks (haven't tested it myself)

I've tracked down the problems in using RESPONSE.write with ZServer.
The symptoms of this bug are an incorrect Content-Length: 0 header,

Hi Petr,

I found the solution to your problem:

Zope here behaves different, depending on if it's running in normal or in
debug mode ("z2.py -D"). The deb package start up Zope in normal operation
mode, while the binary release's start script starts up Zope in debug mode.

When used in debug mode, Zope appearently doesn't cache extensions,
therefore you don't need to tell it that the module has changed. In normal
operation though, it seems to cache them, so that you have to "edit" the
method to tell Zope something has changed.

As I said, I guess it's a performace question and therefore an intended
feature. At least it's no bug in the deb ;-)

Actually, that isn't quite the point.  He isn't actually arguing 
for AOLserver's superiority over every other system, and somewhere
(but I can't find exactly where) he suggests instead:

     Your development technology doesn't matter.

I wish more managers knew this.  You can build interesting
applications in Zope.  You can build them using Java servlets, or CGI,
or WebObjects.  No tool is going to magically solve all your problems,
and solving them will require familiarity with your tools, hard work
and careful effort, no matter what you use.

We had a manager here who was quite enamored of Java, and early on we
wrote some stuff in Java servlets.  He viewed our Zope work as just
stopgaps on the way to Java code that would carry us into the
long-term, but every time I asked "What problem would be solved by
rewriting all our Python code into Java?", there was no clear answer.
Unfortunately, far too many people in business computing follow
a similar management-by-white-paper-and-press-release style.

Similarly, Greenspun argues that you shouldn't re-invent databases; it
would require a tremendous amount of work to add to your home-grown
system all the features that existing databases have -- fancy query
optimization; storage across several devices; on-line backups;
federated operation; etc...  So use an existing system; Greenspun's
preference is Oracle, but he doesn't argue it like a law of nature.

No, you're not wrong; I did have this problem.
Adding /usr/local/lib/python1.5/lib-dynload to LD_LIBRARY_PATH makes
everything behave much more sanely.  :^)  I wasn't able to import
standard python modules (like socket) before, now I can.

And yes, this was a problem with my basic python installation, but
since I'm only using Python to run Zope, I hadn't noticed.

Unfortunately, this doesn't make things better.  :^(  When I run the 'start'
script, I still get the same error:

$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

PyImport_ImportModule: referenced symbol not found


Here's the part I don't understand.  I started stepping through z2.py (isn't
open
source wonderful?!), and trying the import commands one by one in a normal
Python interpreter.  They all succeed, including the one on line 436 which
resolves
to "import Zope".  Yet it doesn't work from within the 'start' script.

Oh well.  I just verified that I can set up Apache+FastCGI+Zope on my
Solaris2.6
box just fine with the binary distribution.  Am I correct that I should be
able
to set up FastCGI using a TCP socket that isn't localhost, and therefore be
able
to run Apache on our 2.5.1 box and Zope on a 2.6 box?  This would let me get
started
using Zope while I figure out how to install from source at a little more
leisure.


Thanks for all your help,

Not a stupid question, and not simple, either.  There are two ways to do it,
and choosing one over the other can be difficult.

1. Store the absoulte_url() of the referenced object, and run this through a
dereferencing method whenever you want to grab it.

Advantages:  If you really want a reference to a *location*, as opposed
to a specific object, this is the way to go.  That is, if you might delete
or
move the object, replace it with another one with the same name, and
expect the reference to refer to the new object, do this.

Disadvantages:  If you expect the reference to follow the object around
if it's renamed, don't do this.  It has to climb up the path to the object
instead of just grabbing it directly

2.  Store the object as an attribute of the referencing object.  This has to
be done (I think) from an External Method, since you *aren't* setting a
property.  You do something like "self.fooref = self.path.to.other.aq_base"
which DTML doesn't allow.

Advantages & Disadvantages: The inverse of #1

Architectures like Oracle with Vignette running atop it are very

Yes, it's a shame, because this model introduces yet another way where
you have to partition your "cloud".  It shouldn't matter what processor
or network gets added to your website "cloud".  Just keep throwing
capacity into the cloud.

Existing scalability architectures have such a schism along the
three-tier boundaries that it takes wizards to implement and operate
them.  Making them, obviously, brittle and prone to problems.

It will certainly take some time.  But obvious things can be solved as a
higher priority.  Since scalability means different things to different
people, though, there isn't One Answer.

I don't feel that advances in Python are absolutely required.  Apache
doesn't have a threaded model (before v2), and if Zope could dish out
requests like Apache 1.x, everybody would be awfully happy. :^)

This begs the question: how fast is fast enough?  These stupid PCWeek
tests, that give MTS a higher performance score than WebObjects because
it claims to do 4,000 requests/sec vs. 2,000 requests/sec, are just
ridiculous.  At 150 requests/sec, you're talking about the top one
percent of websites on the Web.

The other worry is that these super-freaky Python advances will require
cooperation from the app developers to keep the train on the tracks.

Again, I'm not so sure this is the big answer.  I don't think there's a
lot of evidence that Medusa/ZServer is the primary bottleneck.

Yep, this is ultimately an attractive architecture.  Particularly when
you pour all three tiers (presentation, logic, data) into it, you get a
single facility for scaling and distributing all three.

Right, though I'd encourage you to instead speak in terms of the goal,
rather than the solution.  Is the goal here to solve the 2Gb problem on
Linux/x86, to "limit corruption", or is it to do resource accounting on
a per user basis?  As Jim has pointed out, if your goal is the latter,
you won't get there -- user data can still appear in global things like
catalogs.

Jim's counterproposal, which he claims is easier than doing accounting
across separate Data.fs files, is to finish putting accounting hooks
into the object database.  Whenever a user exceeded their capacity (no
matter where the object), an exception would be raised.  This would
probably require that people be able to do their own packing.

I gotta admit, I'm awfully intrigued by this.  It is the kind of thing
that is _seriously_ compelling vs. other architectures, where you have
to keep on-disk quotas for presentation and logic, and in-RDBMS quotas
for data.

Still, the point is, make sure you speak in terms of goals first.

Doubt it.  There's still so much more, such as data scalability (vs. raw
performance).  As for the latter, we at DC _still_ need to make raw
performance go up.

Personally, I think a very smart caching system (where subtemplates are
pre-rendered in ZServer and know when the objects they depend on have
changed) is a huge win for a significant portion of high-load
situations.

Right.  Does this, though, limit them on the platforms you run on
because of assumptions in the threading model?

Right.  But again, this begs the question: what is a "nice site"?  What
if the goal of a "nice site" could be met w/out the disruption of
rearchitecting Python?

Is a "nice site" 100K hits/day?  A million hits/day?  Ten million
hits/day?

This steps into the next part of the problem.  To date, few in the Zope
community has been willing to publish any numbers for highly-traffic'd
sites, despite pleas even from our board chairman.  Perhaps that means
there aren't really any sites where Zope's limit has been reached?
Probably not.  But why are people so reticent to go on the record with
their hit logs?

But it _does_ mean that, until folks are willing to come forward and
provide numbers and test conditions, that we'll be working without a
map.

Subject: [Zope] Python equivalent of dtml-with?
Message-ID: <4.2.2.20000306100755.00b7bc90@saladin.aisys.com>

I'm writing an external method in Python which is going to be used to 
create new instances of a ZClass that I've written.  In my normal DTML for 
object creation, I would do something like this:

<dtml-with "ZClass.createInObjectManager(REQUEST['id'], REQUEST)">
    <dtml-call 
"propertysheets.instanceProperties.manage_editProperties(REQUEST)">
    <dtml-call unindex_object>
    <dtml-call "manage_editCataloger('MyCatalog', REQUEST)">
    <dtml-call index_object>
</dtml-with>

I've got an external method written which is able to create a new object by 
calling the ZClass.createInObjectManager method.  However, I'm not sure how 
to code up the code contained in the dtml-with block using Python.  I 
suspect that I could get things to work for the example above with 
something like this:

(self is the product containing my ZClass definition)

newobj = self.ZClass.createInObjectManager(REQUEST['id'], REQUEST)
newobj.propertysheets.instanceProperties.manage_editProperties(REQUEST)
newobj.unindex_object()
newobj.manage_editCataloger('MyCatalog', REQUEST)
newobj.index_object()

However, I'm interested in knowing how do code up stuff in Python which 
would take into account acquisition.

Thanks.

(AFAIK, the ObjectManager (base for folder) uses this mechanism too.)

Was just wondering, why the 'aq_base' part is required ? What could go wrong if
I just had self.path.to.other ?

Subject: [Zope] Refactoring Question
Message-ID: <4.2.2.20000306104328.00b75dc0@saladin.aisys.com>

I have a DTML method that I would like to refactor but I'm unsure of the 
results I'll get.  In one of my products, I have a ZClass_add method which 
has code which does something like this:

<dtml-with "ZClass.createInObjectManager(...)">
     <do something>
     <do something else>
     <dtml-call unindex_object>
     <dtml-call "method_editCataloger(...)">
     <dtml-call index_object>
</dtml-with>

What I would like to do is yank all the content out of the <dtml-with> 
block and put it in its own method.  I'm thinking that I would like the 
method to live in my product folder, but I'm open to suggestions.  The end 
result would be something like:

<dtml-with "ZClass.createInObjectManager(...)">
<dtml-call initObject>
</dtml-with>

and the initObject method would be contain

<do something>
<do something else>
<dtml-call unindex_object>
<dtml-call "manage_editCataloger(...)">
<dtml-call index_object>

My first question is, if I create an initObject method in my product 
folder, if I call it from within my dtml-with, will it execute exactly the 
same way as if it were included inline or would it somehow lose the fact 
that it was executing in the context of the "with" object?  I'm thinking 
that the "with" information is put on the namespace and the namespace will 
be available with my initObject method is executed, but I want to confirm 
that my thinking is correct.  Alternatively, should I define my initObject 
as a method of the ZClass itself rather than defining it in the Product folder?

Thanks.

There is a "deprecated" way of doing it, but the thread got off track
without a real answer (the "right" way). The "deprecated"  (the

ZScheduler. It works like this:

In __init__.py module:

In class definition.

Message-ID: <38C3DBD4.A31D2482@ep.newtimes.com>

Does anyone know how to logout a Zope user?
Basically I need to be able to force an authenticated user back to the
'Anonymous' user
programmatically. (when someone presses a logout button, etc.)

Also, how can I change the message text in the login popup window?
Currently it says something like, "Enter username for Zope at
foo.bar.com:"
I would like to be able to modify this depending on where someone is
logging in.

I'm trying this on SunOS 5.5.1, and am getting more less the same
results. See my other article [Problems Installing Zope]...

I have tried adding both the python dynload directory, and even
the Zope/lib/python directory to LD_LIBRARY_PATH, both of which
are no help.

The error I get is a little different:

File "/new1/misc/Zope-2.1.3-src/lib/python/ZODB/__init__.py",
line 85, in ?
  import sys, ExtensionClass, TimeStamp, cPersistence,
Persistence
ImportError: No module named ExtensionClass.

As mention somewhere in this thread, this all stems from line 436
in z2.py :)

Any ideas?

   Strange. Just a check: you wrote '-appConnTimeout 0', aren't you ?
mod_fastcgi is case sensitive (or at least it seems so at the first glance at
the source).

   No, they are only used to report to the webserver. As stated there,
mod_fastcgi doesn't even ask for them.

This is true, he doesn't necessarily argue for the superiority of
AOLserver vs. the world, and that is not what I said either. However, he
strongly advocates for AOLserver, which is fine it is good work. But he
and others who follow have also advocated against extending AOLserver
for tools other than Tcl/ACS. He says, after all, what for?

This is true, but it isn't wrong to want to do your job with a tool you
enjoy. In the event that there are multiple qualifying ways of doing a
job within reasonable means of quality, I think a tool you like and
enjoy would potentially help and enable productivity. There is not
necessarily any magically programming language or tool. However, some
are better than others. Programming well, requires effort and work.

Because something requires effort, even tremendous effort doesn't mean
it isn't worth it. Because something may duplicate features of another
product doesn't mean it isn't worth it. Linux did all of this.
Tremendous work and effort to somewhat duplicate available software. At
some point the efforts which could be perceived as a duplication of
existing software may at some point supplant and exceed the currently
available existing systems. Subsequent versions of many existing
software packages can also fall into this same description of tremendous
effort, to duplicate the features of existing software. But this is
generally for a reason. Some times to improve certain things,
performance, add features, interoperability, portability, etc. I'm sure
Oracle has done this. I'm sure Philip has.

In his forum and other writings Philip has openly argued against most
any potential competing database to Oracle. In his argument he believe
the price of Oracle isn't/shouldn't be a problem. However, to many
people it is. Even though his webserver of choice is db agnostic, his
software ACS isn't. It is very much hardwired to Oracle. Talk to the
people involved in the ACS port to PostgreSQL.

Any advancement of technology will come at a price of tremendous effort
and duplication of current capabilities and features. Sometime it's
worth it, sometimes not.

Philip is right on many of his points. How much has software really
advanced from the capabilities in Lisp from so many years ago? Very
debatable.

As I said his book is a very good read, great material. I like many of
the business ideas and practices of ArsDigita. I have populated my
library with many of his book suggestions.

I have absolutely nothing against Philip, ArsDigita, AOLserver, ACS,
Tcl, etc. AOLserver/ACS is a great tool and toolset. However, in the
discussion of comparing AOLserver/ACS (really ACS) to Zope it basically
boils down not as much to features but to design/architecture of each
tool and scalability. Some people will prefer the ACS way over the very
OO way of Zope, some the opposite. If you are agnostic on such, then
scalability may become an issue. AOLserver/ACS and Zope scale
differently. Philip has a distinct view scalability. Farms, clusters,
no. Single machine, multi-processor, yes. Database == Oracle (his other
uses were also big $$$dollars). Hence scalability == $$$dollars.

AOLserver/ACS currently scales better than Zope. Zope may not currently
be the best choice, or a choice, for Amazon, Ebay, etc. But I think it
can someday. Because Zope is reasonably db agnostic (it does like
transactions), it may be a better solution for many people than ACS
since it is tightly linked to Oracle. If your money and data is
somewhere else you would have to port. In their forum I made comments
that it would be great if ACS were decoupled from it's specific database
dependency. The db connectivity could be abstracted and an appropriate
database api could be created. This would enable other database users to
use ACS. No interest from ArsDigita. Instead there are various peoples
rewriting ACS for their db of choice. As far as I know all hardwired. :(

There is definitely room for both to be successful, and others like
Enhydra. Then there would quality choices for users of various
backgrounds and personal preferences.

There is most definitely a give and take among the choices out there for
languages, webservers, app servers, etc. As for me, when surveying the
landscape from my world view and perspective, the other options
primarily potentially beat Zope "currently" in scalability/performance.
But for me Zope won other areas. I like Zope, I like ZODB. If I don't
have to use an RDBMS, I won't. However, I do hope for ZODB to improve to
the robustness and scalability of the RDBMSes. For some uses it is.

As I read the paper today and see 1 ghz Athlon machines becoming
available, Zope horizons are looking better. Go Moore go. :)

Subject: [Zope] Comparing "unsized objects" and strings
Message-ID: <38C3ED35.C507DF33@newopenness.de>

Hello all,

I have a little problem. I know where it is, but not how to solve it :-)

I have a DTML document:
---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- aid comes from the result of the externalMeth -->
</dtml-in>
---snap

Okay, no problem so far. But when I want to compare the value to a
parameter I have given to the document via a <FORM>:

---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- Okay, works fine of course -->
<dtml-if "aid == param">
Hi there!
</dtml-if>
---snap

The expression evaluates always to false. I have traced the problem back
with an external method ("<dtml-if "equals(aid, param)">"). When trying
the "len" function on both variables, "param" is not a problem (it's a
string from the the <FORM>), but "aid" complains that it was an "unsized
object".

How do I compare them?

Thanks in advance
  Christian

hmm .. untested:

<dtml-if "_.str(aid)==param">

_.str(aid) should return a string presentation of aid.

Woohoo! Absolutely. :)
However, if a multi-threaded/multiprocessor capable Python were
available to embed into AOLserver then it seems to me that the improved
performance would be transparent.

This is true if the requests are evenly amortized throughout the 24 hour
period. Unfortunately they aren't. For me fast enough means that your
machine is not maxed out (or croaking) when handling peak loads. Your
visitors handle the speed/latency well. It is all very relative.

I agree. I was just hypothesizing. I would generally prefer to keep with

True and maybe not. However as Zope pushes into heavier trafficked
environments who knows. But we'll take whatever speed gains we can. :)

What I like about this is the capability of distributing your work load

Actually not necessarily either. I don't want data corruption, so if
that's an issue it will need to be addressed. Say for example I have a
very large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5gb directory which is reasonably stable
updated monthly.
ZAuto/manufacturers isn't so large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.

My example above doesn't fit into this situation, at least as far as I
can tell. There are no user quotas or explicit restrictions.

I have somewhat lumped raw performance and scalability together. In many
ways they are hard to separate. I agree a smart caching system would be
nice and a tremendous boon to performance. In Philip's writings, he
believes that performance is best when the entire db resides in memory.
Sometimes that is not possible. However, if you cache the most often
accessed parts you reap tremendously.

I don't know, I am not a threading expert. However, with AOLserver, I
believe that stayed with the POSIX model. So if Python was such it seems
it wouldn't be a problem in most cases.

Yes, this is a very subjective area. My original problem with Zope's
scalability and what would scare me with a site is the inability to
throw hardware at it. ZEO didn't exist then. The question exists though
is if a Zope based website was getting 1 millions hits a day and gets
Slashdotted or some other such phenomena and in a few weeks or months
grows to 5 or 10 million, what are their options within Zope? Where will
the bottlenecks come from? Can they throw hardware at it? What if
tomorrow my "Slamazon" bookstore went online and was an instant success?

It does, but the "string" is still an unsized object. 'Scuse me, I
thought Python is not strong-typed?

I'd have thought someone would have answered you by now. Have a look at the
Zope Quick Reference:

  http://www.zope.org/Members/ZQR/

Also, looking over the doc/CHANGES.txt file can give you lots of clues about
new features that may not yet have been documented.

If I am understanding you correctly, you should have a look at Loren
Stafford's ZScheduler. Download it from Zope.org, and look at the code for
the ZEvents. They are catalog aware, and override manage_afterAdd, then call
the superclass method.

Hi,

What versions of Zope (probably 2.1.4) and what versions of MySQL work together?   I have tried unsuccessfully to get MySQL to work with the the MySQLDA using the latest stuff.

     Keywords:  Management Interface 

 Submitted by:  Dylan Jay djay@innocent.com
-------------------------------------------------------------------
 When I create a ZClass with my own management methods they 
 will by default use standard_html_header etc. This doesn't look 
 like the standard management interface. I think we should have 
 a standard way of making all management interfaces look the 
 same.  In fact this should be able to be changed for any subset
 of management interfaces so you could for instance change the
 way the standard zope interfaces look.

Dang!  Another "lead zepplin" topic!

Perhaps everyon was holding off because they expect that the
management interface is merely a short-term, necessary evil, to
be replaced RSN by:

 * The "Zope Studio":http://www.zope.org/Resources/Mozilla/index_html
   project, which uses Mozilla's way cool XUL technology to build
   "Zope-aware" chrome in the browser?

or:

  * The upcoming Model-View-Controller
    "re-archictecture":http://www.zope.org/Resources/Mozilla/ZWiki/ModelViewController 
    project, which works to divorce the HTML presentation (the 
    "view") from the underlying Python objects (the "model");
    this is enabling technology for ZopeStudio, the 
    "ZIE":http://www.zope.org/Members/johanc/ZIE/ZIE-demo cognate
    for InternetExplod^Hrer, a wxPython and XML-RPC client like
    the one Amos Latteier
    "demonstrated":http://www.zope.org/Members/Amos/XML-RPC 

or:

  * The "Portal Toolkit":http://www.zope.org/Products/PTK, which
    replaces much of the current management interface with new
    "wizard"-based configuration tools.

I'll close by thanking Dylan Jay for suggesting the topic, and
for his thoughts on potential solutions.

Keep those cards and letters coming!

     Keywords:  ZClasses 

 Submitted by:  Tres Seaver tseaver@palladion.com
-------------------------------------------------------------------
 When building a Product using ZClasses, I often want to create
 a "root" ZClass, which the manager will create in a normal
 folder, and which will then expose the Product's other ZClasses
 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel
    +- FooProduct
       + FooItem_add_permission
       +-FooRoot
         +- FooItem
         +- FooItem_add

       + FooRoot_addForm
       + FooRoot_Factory

Hi everyone,

I'm asking this question again because I still haven't been able to work
it out for myself. I'd like to have a button or link on a page that, when
pressed, presents the user (the Manager actually) with a dialog to upload
a new version of a file object that's in that directory. I presume that
the manage_upload method would do the trick, but I can't figure out how to
use it.

The file object I want to update is called 'Bookmark.htm'. I'm trying to
make it easy for our school librarian to distribute our standard bookmarks
to all of the machines in the building.

ZCache caches method results.  It's kinda broken and not very extendible. 
I'm writing GenericCache as a replacement, but it'll only be finished when I
have enough time.

Message-ID: <7502CAC76F59D211B0090000F8662FA305F43EE7@ap3expr3applge.appl.ge.com>

All - After bringing up a logical interface (hme0:4) on physical interface
hme0, Zope will not work if I try to use a value of 80 for the HTTP port.
Netscape Enterprise Server is running on this same box and is already bound
to the physical interface hme0 listening to port 80.  My guess is that Zope
is not really binding to the virtual interface, but is trying to bind to the
physical interface and thus it is conflicting with NES.  The error follows:

$ ./start -a 3.130.232.27 -w 80 -f 8021 -m 8099
Traceback (innermost last):
  File "/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/z2.py", line 493, in ?
    logger_object=lg)
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/http_server
.py", line 552, in __init__
    self.bind ((ip, port))
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/asyncore.py
", line 205, in bind
    return self.socket.bind (addr)
socket.error: (13, 'Permission denied')

3.130.232.27 = hme0:4

If I specify an HTTP port that is not currently bound to the physical
interface (hme0), such as 1234, Zope starts up properly.

How can I force Zope to bind to logical address 3.130.232.27:80 so that it
no longer conflicts with NES?  Is this even possible?  I have a few Zope
apps. that I would like to bind to different logical interfaces on port 80
so that I can use different hostnames.  Additionally, I do not want the
user(s) to specify a port in the URI.

Thanks,
-Brian

LoginManager is a thing that aims to replace user folders.  It accepts
plugin User Sources (which know about users) and Login Methods (plugins
for different methods of logging in -- things like Basic Auth, Cookie
Auth, etc).

You can get it from the ZopePTK CVS. (It's useable without PTK, though
-- there's nothing PTK-specific about it. It's just that it's
particularly useful for PTK)

LoginManager currently comes with a default User Source called Generic
User Source (GUS), that is a GUF-like roll-your-own system.  It uses
GUF-compatible methods (userExists, userRoles, etc), so converting any
GUF-using site to a LM site should be pretty easy.  We plan to write
another User Source that is a simple ZODB-based plugin that parallels the
current plain User Folder.  Other existing User Folders (etcUserFolder,
etc) could/should be converted to user sources. 

One advantage is that you can have more than one user source, so if you
need to have employee logins from your corporate LDAP directory and
customer logins from your Oracle database, you can do that. The
implementations of each can be completely separate and reuseable.

Another advantage is that there is no longer the "n times m" problem of
login methods.  If someone writes a PostGresSQLUserFolder that does SSL
client certificates, there's no easy way for you to use that SSL client
certificate capability with etcUserFolder.  But with LoginManager, if
someone writes a SSL client certificate Login Method and someone else
makes an etcUserSource, they automagically work together.

There are some other cool features too, and more coming.

By the way, for those of you who were at IPC8 and were confused by the
RIPP Patterns talk (which is everyone who attended, I think ;->),
LoginManager is so far a good example of at least the RI part of it.

LoginManager is the Implementor for users (it's just called acl_users
instead of I_User :->). User Sources are really Racks. 

The "things from different authors automatically work together" nature
of LoginManager is exatly what RIPP is for. Now that we have an example,
maybe we can try to explain it better and get other people using it for
other things :-)

Despite your following (very good) points, this is not true.  It leads
to conclusions like "Perl is just as readable as Python", "Let's just
use C, it can be made as portable as Java", "We should use Lisp for
this 3D first-person shooter, we just need a better algorythm than
previous C implementations."

A better way to phrase this is:

	Your development technology is only one piece in a larger
	puzzle.

I've recently switched a rather large project from Java to Python --
throwing out nearly 2 years of work in the process -- and I have
noticed an immediate increase in development speed.  Changing
development technologies was a GREAT idea; but only because it was
considered within the framework of the developers we had, the skills
they had, and the relative advantages of both frameworks.

The project had a high dependence on lists and hashes.  Changing to
python increased performance (all these data-types are native in C, in
python; profiling our code shows that it spends most of its time
inside java.util.Hashtable), scalability (Java has lots of hard limits;
a max of a few thousand interned strings, 32M of RAM per process unless
you start diddling command-line arguments, and GC gets unbelievably
slow if you do that), reliability (the JVM on Linux is buggy; python is
pretty robust if you're not using any crazy native modules ^_^), and
last but not least, we get the source to our tools so we can improve
them ourselves.

Certainly, nothing is a magic bullet or a panacea that will make all
your development problems go away, and I doubt that anyone reading this
list believes that.

Coincidentally, if you are, and you do, I have a GREAT WAY to MAKE
MONEY FAST with NO INVESTMENT!!! It is NOT MLM!! ;-)

This is a great point.  Considering the technology within a coherent
whole is EXTREMELY important, and the view of some managers that
something is just going to be a panacea that resolves everything is
depressing.  It's not limited to development technologies though -- it's
"employee empowerment", it's "diversity training", "thinking out of the
box"... bad management transcends the boundaries of space and time =)

In my experience (I admittedly haven't read this particular article)
Greenspun's advocacy of Oracle and WebDB is near-rabid and biased
toward extremely high-end applications for people with lots and lots of
money.

What you're referring to as "re-invent"ing, by the way, is referred to
by some as 'innovation'.  However, I will agree that the time to do
that is not necessarily when a large project is nearing a deadline...

Finally, I think Zope is a great tool, and for some applications (making
a Slashdot clone, for example) it DOES have the kind of killer advantage
that can make it worthwhile to switch lots of work in another system to.
 It all depends on what's appropriate though -- if, for example, your
site needs to have access to AdaBase, I don't know if Zope is the best
way to go.

I have actually seen projects for which CGIs written in C++ were
unquestionably the best choice.  Examples like that are rare, but they
do exist.

Hi,

I'm running Zope 2.1.14 on Redhat Linux 6.1. I would like it to start 
automatically when the computer boots. I'm looking for a workable rc script for
this configuration.

I tried the script found on the How-to: Installing and Upgrading Zope 2.X.
On start up the computer displays the messages "Sarting Zope2 service: ".
However it doesn't go further and I have to reboot my computer. Thanks in

Here is the script I used. Thanks in advance.

You didn't say what problems, if any, you are having, so I'm just going to
take a shot in the dark.

By choosing a DTML Document, clicking on the Upload tab, and viewing the
source, I believe you need something like:

<FORM action="manage_upload" method="POST" enctype="multipart/form-data">
<INPUT type="file" name="file" size="25" value=""><BR>
<INPUT type="submit" value="Change">
</FORM>

Make sure you don't leave out the enctype attribute or things will be
unhappy.

Let me know what, specifically, doesn't work if you continue to have
problems. I'll do my best to help.

Out of curiosity, are you running (lauching) Zope as root? The lower ports
(below 1024?) are privelaged on UNIX, and require root permission to bind.
Higher ports, such as 1234, are not; anyone has access to port 1234.

We have a Solaris 2.6 box here running Zope 2.1.4. We launch ZServer with
the -a parameter specifying our interface, and it works like a charm. I
suspect this is not interface related.

Look at the management form that you see when you create a File object, and
do what it does, only in the context of your user interface.

Thanks Jeff...that was the problem...all of my Zope instances until now have
been started by uid zope.  Rather stupid mistake, but a learning experience
nonetheless.

Thanks again,         -Brian

Anywhere inside the "main" folder, you should be able to write <dtml-var
expr="sub.message">.  Outside of "main", you would have to write <dtml-var
expr="main.sub.message"> or possibly <dtml-var
expr="f1.f2.main.sub.message"> if "main" is in "f2" is in "f1".

If I'm understanding the problem correctly, try:

Wade, the best you can do with basic authentication is to do something
like:

<dtml-raise Unauthorized>
 You are logged out.
</dtml-raise>


However, if the clicks cancel on the login box that pops up (there's no
way to prevent it from popping up), he or she will still be logged in.

Use cookie-based authentication if this is a constraint.

You can use the environment variable Z_REALM to change "Zope" to
something else in the login box text.

This looks right.

Acquisition is built into Zope objects; the only time you should ever have
to "take [it] into account" is if you are trying to acquire an object with a
non-identifier Id, or whose Id is stored in a variable.  In these cases
"anobj.aq_acquire('foo.html')" and "anobj.aq_acquire(fooname)" should do.

Yesterday I had to restart NS no fewer than 5 times, to prevent the
'swap-to-death' situation.  I have 96M in my machine, and i've been careful to
eliminate all extraneous tasks to reduce memory usage.

Yes, memory is cheap, but to get this box to 96M (from the original 32) took
quite some wrangling, since it seems ordering more RAM here can have at least
an 8 day lead time, amongst other things.

As a programmer myself (ZOPE is like a holiday :) I know that memory leaks can
be easy to code, and tiresome to track.  But in an application as large as
Netscape, I would hope for slightly tighter quality controls, and a little more
coding discipline.  There are some fairly simple guidelines you can follow to
write "zero resource loss" programs.

Yes, I looked into Mozilla yesterday.  However, I discovered it will ONLY work

don't have ANY other apps using it.

Greetings,

I have used MySQL 3.22 (Stable) and 3.23 (Development) with Zope 2.0.1 through
2.1.4.

I am currently using them with the ZMySQLDA version 1.1.3, along with MySQLdb
version 0.2.3.  There is a very good howto on installing these.  I have
recollections of compile problems on my first attempt, but it turned out I was
tryring to compile something that was obivated by MySQLdb.  So, follow the
instructions carefully.

Subject: [Zope] Frequent Zope Restarts and GUF authentication
Message-ID: <m3k8jf4svq.fsf@wacko.pdx.net>

I have a server that is being run in production mode without the
-D flag.  The server processes die after about two hours.  I haven't
seen the actual crash yet nor have any users complained about error
messages.  I know the server is restarting because the Control_Panel
tells me so.

Well, the real problem here is that since my site is protected with
GenericUserFolder in cookie mode, GUF's cache gets wiped when the
server bounces.  This forces my users to log in again.  

Two questions, 
  Any guesses as to what's causing the mysterious restarts?

  Any idea on how to resolve the GUF problem?

Zopists,

Has anyone else noticed that the endmail tag will sometimes not send a

out of ten at high traffic times, and it happened on Zope.org too when I
tested it by emailing my password to myself a few times.

In this context 'cache' is the in-memory cache of Persistent objects
(most objects in Zope are persistent, for example, just about everything
you can add or manage in Zope is persisent).

Obviously, it's not very good performance to read and write all objects
to and from the database everytime you use them.  Therefore, there is a
cache to speed this up.

The 'target' is the number of objects in the cache.  Note that this is
not a very hard limit, ie, if you set it to 10, it will let you load 10
tiny objects or 10 huge ones.  Or 10 of mixed size.  Experimenting this
this value and watching how much memory Zope consumes is a good exercise
in performance tuning.  Note that there is NO magic value here, you have
to play with it.  Keep in mind that the default is very conservative,
you can definatly start playing with it in the up direction (unless your
running on a 386 with 16MB of RAM...).

I am also trying to get MySQL running with Zope 2.1.4.  I'm trying to follow

I got to the part about Expand and Install MySQLDB but I am stuck.  In the
installation README, it says to read Setup.in to verify the paths.  I have
no idea what those paths or for and I don't have them on my Linux system.

Does anyone know what these paths are for and how I can determine what I
should set them to?

I have MySQL 3.22.32, I'm trying to install MySQLdb 0.1.2 and ZMySQLDA 1.1.3
per the alanpog HOWTO

Curtis, what is the really good HOWTO you mentioned?  The one I found is
very brief and isn't helping me much.  Also, where did you get MySQLdb
version 0.2.3?  The latest I saw was 0.1.2.

David, did you manage to get past the Install MySQLdb step?

Thanks,

Hi,

Something that seems maybe very trivial, but I did'nt find the solution.

I have a very simple class ItemId (metatype ItemClass) which is only a
subclass of Image and has no property sheet.

When I try to create a new instance I get the following message : 

Error Type: TypeError
Error Value: argument file was ommitted

Here is my addMethod:

.......
<dtml-with "ItemId.createInObjectManager(REQUEST['id'], REQUEST)">
<dtml-call manage_upload(REQUEST['myimage'])

</dtml-with>
......

Where 'myimage' is the name of a field of type file in my input_addForm.
I works fine when I use manage_upload with an Image but not when it is a ZClass
subclassing an Image. Where am I wrong?

Thanks.

Thanks, that sounds like what I'm after.  I don't quite understand why
this is not setting a property.  Can you point me to some documentation
that might help explain the difference?

I guess putting in a little Python is no big deal, but it does break my
ultimate goal of letting non-technical people create new classes of
content.  Is there any plan to add inter-object relationships to ZClasses?

what about the options in fastcgi?  processes in FastCgiServer defaults to 1. 
-maxProcesses defaults to (50)  >-maxClassProcesses defaults to (10)

will increasing these numbers help stop connection refused error?

fastcgi is a like a black box to me, full of mystery, even after reading the
docs.

I hope you got your setup working, Jeff.  Your rewrite rules look
good to me.  But I want to take this opportunity to make a (tested)
alternate suggestion for the rewrite rule.  The above rewrite rule
has the unfortunate feature that URLs like ".../Zopestuff/etc"
match the rewrite rule and get turned into the (not found) path
.../cgi-bin/Zope.cgistuff/etc.  This isn't a problem normally, but
you can perhaps imagine having Zope under a directory with a given
name but wanting another URL with that same name as a prefix
substring to also work (.../news and .../newsimages perhaps?).
I've come up with what I think is a better regexp for use in this
kind of rewrite rule, mostly to avoid the surprise factor of later
having a Zopestuff type URL mysteriously fail to work on me someday:

.../Zope(/.*)?$

which is mapped to

.../cgi-bin/Zope.cgi/$1

The ?$ means that the /<stuff> all the way to the end of the URL is
zero or one time.  So Zope by itself matches, and Zope followed
by a / matches, and Zope followed by /stuff matches, but Zopestuff
does not.

FWIW

If MySQL does everything you need, it is probably the better choice.
GenericUserFolder is more complicated to setup (so it appears better
supported as their are more questions), and exists to support sites
with more unusual requirements.

an acl_users folder only authenticates the sub-tree it is defined in.
If you want AUTHENTICATED_USER available in /home, then move your
acl_users folder into that folder. Your users will not be required
to login if they access stuff that is available to the Anonymous role,
but if they have logged in, AUTHENTICATED_USER will be set.

The problem line is <dtml-if "e">. What I was intending to do is
perform the code if the search result actually returned something, but
this doesn't seem to be happening. What I'd like to do is:

<dtml-if "len(e) > 0)">

But, len() doesn't seem to be defined in whichever namespace the code
is being run in. I tried:

<dtml-call "global len">

before the dtml-if, but this errored out as well. Am I completely
misunderstanding the problem which I'm having?

Thanks.

Good luck. :(

 Browsers and servers are neither required to, nor are (to my knowledge)
respecting any sequence of form fields. Basically, IME, if you need the
data going in somewhere to be in the same order ( a program that expects
certain values in certain a order, for example), have whatever processes
the returned data order it for you.

I've just been testing, to see when the most leaking occurrs.  It's definately
whenever I type in the edit box.  At one point I hit enter, and it grew by over
300K.  As I type, I can watch the size grow.  It's really that fast.

As I type, I am downloading the NS RPMs from RH6.2, which seems to be a few
steps ahead of the 6.1 updated i have (From 4.7-1.1 to 4.7-4 .. doesn't look

Much appreciate the effort.

Someone even suggested it might be my Motif lib.  KDE, afaik, catches all the
Motif calls and replaces them with its own widgets.  A workmate running Gnome
checked the same situation, and the memory leaks in just the same way.

scratch another theory.

To use len, try:

  <dtml-if expr="_.len(e) > 0">

It is part of the _ namespace.

You may also be able to achieve the same result (depending on the types of

  <dtml-if e>

Ok, it appears that len() isn't what I want. I was under the
impression that searchResults() returned an object which functioned as a
list, but this wasn't right, apparently. Or maybe it was, *shrug*. :)
Here's my current code, which I've modified a bit for testing
purposes:

<dtml-var standard_html_header>

<dtml-call "setCalendar('valign','top')">

  <dtml-var dprop>

This code generates links as it should. What I'm trying to do though
is, if an object of the Event class exists with an event_date which
equals the current rendered date, I'd like to link directly to it. I can
successfully search for the date using the PTK's search form, so I'm
fairly sure that my issues with the catalog are resolved.

So, what exactly is being returned by searchResults, and how can I
determine whether my search yielded anything, so that I can display a
link to the item?

Not if you do not name them explicitly. The REQUEST.form.items() is a
python dictionary. Keys of a dictionary have no fixed order. You could
sort them if you wanted to, but that would be a computer order, not the
original order in which they appeared.

I had a system where it failed (also silently) every first time after reboot.

I just moved to an external method that used /usr/sbin/sendmail as I did 
not have enough time to start debugging. Telnet to port 25 had just a very 
long (>30 sec) startup time, probably some DNS problem. 

AFAIK Zope does not (for some unknown reasons to me) use pythons SMTPlib 
but has rolled their own smtp interface.

It has also been reported to fail with MS Exchange server, which someone 
fixed for himself by swithing to smtplib. IIRC the patches were also posted 
to zope or zope-dev list.

IMHO the right solution for Zope would be swithing to smtplib, and if there 
are faults then fix them there (and maybe include fixed smtplib with Zope 
until fixes are included in mail python distro). There is no need to invent 
to similar but slightly and differently broken wheels, at least in Open 
Source Software there aint.

Message-ID: <4.2.0.58.20000307085505.00c2ee80@195.60.12.162>

Dear Zopers,

I read Chris McDonough's How To on Gaining Zope Enlightenment by Grokking 
Object Orientation. It raised a few questions in my RDBMS-oriented head. So 
I mailed Chris with these questions but Chris explained he just couldn't 
answer them right now and asked me to post them to the list. They seem very 
basic, very fundamental questions to me.

So here is my email to Chris - If I get any answers here I would like to 
include my questions and your answers in a How-To to help those who come 
after me !

Thanks for any help !

Here's the original email

---------------------------------------------------------------------------- 
----------------------------------------------------------

Chris,
I enjoyed your How-To on Gaining Enlightenment very much. I've been using 
Zope for a couple of months now and I've made some progress - my first 
project has been to use it to give access to established databases over an 
Intranet. Like you I think its wonderful, but like you I keep getting 
stuck. Never mind, with the help of the mailing lists and long hours 
reading books on Python etc I've made progress.
BUT ... (there's always a but isn't there) - no matter how much I read and 
play around with OO - I still don't 'get it'. My background is many years 
working with relational databases on Unix - (and there are thousands like me).
I just don't get the bit about storing data as objects. Could we discuss 
this a bit more and perhaps publish my questions and your answers on 
Zope.org ?? This may help me and the thousands like me.
OK, you create your class of Spam, which has attributes of cansize and 
texture and it has methods that display these attributes. No doubt you 
could add other attributes, such as selling price and develop a method to 
increase the price by a percentage. OK so far ?
Now we create an object (which is an instance of the class Spam) - which we 
call myfirstcan. We can define the attributes for that object when we 
create it or later and we can use the methods defined in the Spam class to 
do so. OK so far ?

What I don't get is how you store and retrieve the objects you create. 
Let's go to a more realworld example - how would you implement a stock 
system using objects ? Let's take the simple table Stock which has three 
columns
Product_code Description Price
and we could enter rows of data into it, for example -
ABC Spluggifier 20.00
CDE Super-spluggifier 25.00

Now if I was writing a conventional database system I would maintain the 
above by defining a program which perhaps prompted the user for the 
required columns (Product, Description,Price) and then I would store the 
users input in a row in a table. Perhaps another program (the price change 
program) would use a stored procedure to allow price change. OK ?
Now in OO terms I see that I could create a class of Stock with attributes 
Product, Description and Price. I could create a method to allow price 
changes. Very neat.
Then I can create an object( i.e a particular stock item) by saying 
something like
product_1 = Stock(product_code="ABC", Description="Spluggifier", Price-"20.00")
Now I can create another object by saying
product_2 = etc
but that is not the way you would do it surely. You would be effectively 
'hard-coding' each product in your system.
Surely you would have a program which did something like
WHILE the user is entering data
PROMPT user for data
VALIDATE data
WRITE data to database
END WHILE
How do you do that in OO terms ?
How then do you search and retrieve an object with a particular value of 
product_code ?
How do you write a program which updates the price of all stock items where 
the product_code begins with AB by 2%.?
Thanks for reading this far. Hope you can stop my head spinning !

Regards

Richard

I'm still having difficulty with this.

I want to add a date to a character string ( dated user comments ) to
store into a sqltable.

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">

The docs say that this returns a date string ( as opposed to a date
object? )

<dtml-call "REQUEST.set('mystring', 'date: '+CurrentDate)">

produces this error

Error Type: TypeError
Error Value: illegal argument type for built-in operation

And if I try this

<dtml-call "REQUEST.set('mystring', 'date: '+_.str(CurrentDate))">

mystring is then 'date:'

I have not obviously researched this in detail (perhaps you may want to)
but I do not believe that the any of the various web rfcs define that
either the client or server should send/expect any form elements in any
explict order, and that if any order is mentioned at all it is probably
'implementation defined'.  The introduction of various CGI interface
libraries for various languages probably munges this even further.  I
would not rely on any consistent order at all coming from any system.

We wrote the sendmail tag before smtplib was written.  At the time there
was no existing standard smtp client library in python.

a sequence of record objects that describe cataloged objects that match
your search query.  The are NOT the actual objects themselves, just
'descriptions' that can be used to refer to the objects (with 'getpath'
as you discovered, or 'getobject').

In your case, 

<dtml-if e> 
    There are results.
<dtml-else> 
    There are not results. 
</dtml-in>

I don't undertand what you mean, you code apears to do this.

BTW, it is much easier for other people (or at least me) to assist you
if they can read your code.  For python programmers, this means
indenting it sensibly.

You can do this, but you must be sure you understand that your object
now references the other object without the Zope framework's
'knowledge'.  This is not a bad thing and happens all the time, but you
should be familiar with what this does to things like garbage
collection, persistent object deactivation, and circular references.

I don't know what you were trying to do before, so I can't answer this.

You mean references?  We've thought about this problem a little and Jim
and I discussed this over Chinese buffet once, I obviously had less of a
clue than him, but I belive the result of our discussion is that there
should be some sort of standard for one Zope object to refer to
another.  The simplest way we could think of is simply storing the
path.  Such as:

attribute = "../../relative/path/to/other/object"

or perhaps:

attribute = '/absolute/path/to/object'

Then when you want the object you ask Zope to resolve that path for
you.  Currently you can use REQUEST.resolve_url(attribute) to do that
for you.

If you're not working on python you can simply set a string property as
the path.

This is how ZCatalog does it (actually ZCatalog uses a slightly dumber
version of this concept, don't ask).  HOWEVER, the lack of any kind of
standard or support for such references in the framework has bitten
ZCatalog (and webdav) in the past, and the decisions we made will
probably come back to haunt us real soon now.  You have been warned.

This patch replaces the socket-base code with smtplib calls.
The original MailHost didn't work with our Exchange 5.5 server, but after I

Subject: [Zope] copying image object?
Message-ID: <200003071209.AA19294@rsphy9.anu.edu.au>

Hi Zopistas,

A likely FAQ but it's late, I've been Zoping for 15 hours, ZQR 
is temporarily unreachable from Canberra, I can't see straight
and I'll admit it - I'd like to wake up to the answer ...

I simply need to copy an image object (image1) from my
globals folder to within an instance of a containerish 
ZClass.  I toyed with manage_addImage() but couldn't
find a method to get the raw data out of image1. 

Cheers,
Darran.

Subject: [Zope] Tricky usage of string to integer conversion
Message-ID: <000001bf8839$b997a5e0$0b00a8c0@nassau.islands.net>

I am trying to do the following:

<dtml-let x:int="REQUEST.get('prod_config')"
          item="_[REQUEST.get('prod_id')]"
          price="item.price_list[x]">
    <INPUT type="hidden" name="chargetotal" value="<dtml-var price>">
</dtml-let>

The prod_config variable is a number (returned as a string) from a SELECT
list.  The prod_id variable is the id of an object in the same folder as
this method that has a price_list attribute.  price_list is a list of
strings representing prices.

This results in a "Name Error" where Zope cannot find "x".  If I change line
3 to this:

          price="item.price_list['x']">

it fixes the Name Error, but then I get a "Sequence Index must be an
integer" error on price_list['x'].  I would have thought the use of "x:int"
in my <dtml-let> would take care of this issue.  Seems I can't win!

Does anyone know the correct way to do this lookup?

Brian Holdsworth

"dtml-let" doesn't understand type annotations, so you are setting a
variable called 'x:int', which isn't what you want.  You need to do the
integer conversion in Python, like so:

<dtml-let x="_.int(REQUEST.get('prod_config')" ...>

See the DTML reference guide at zope.org for more useful methods of "_".

I think it must be converted by the atoi method of the string module:

so either:

<dtml-let x="_.string.atoi(REQUEST.get('prod_config'))" 
          [rest of your code]
or:

<dtml-let x="REQUEST.get('prod_config')"
           item="_[REQUEST.get('prod_id')]"
           price="item.price_list[_.string.atoi(x)]">

This is the same problem as last time. You must CALL the Date method, not
just reference it. The above line should read:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date()">

Note the use of parens on Date().

Try it for yourself by putting the following in a DTML Method:

  <dtml-var expr="ZopeTime().Date">

You get:
  
  <method DateTime.Date of DateTime instance at 568eb0>

if you do a View | Source in your browser.

It does, if you CALL it.

Here is some code that works:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
  <dtml-call "REQUEST.set('mystring', 'date: ' + CurrentDate)">
  <dtml-var mystring>

Again, you've never set CurrentDate correctly. View the source of the page
that comes back and you will see the problem.

Hope this helps.

It supports it to no greater or less extent than Linux does.  The
standard library defaults to using an int or a long for *seek calls.
The difference is semantic only, as they're both 32 bits on both
systems anyway.  Even if you assume unsigned (fseek is signed), that's
still 4gb, max.

However, on my Linux/Alpha system, a long is 64 bits.  This
effectively removes the problem.

I submit, therefore, that you are not seeing a Linux problem, but an
x86 problem :-)

Why?  This is overkill for what zope is.  Zope is not, in essence, a
web server.  If you want to do strange things like that, use Apache
:-)

Completely inaccurate.  Proprietary software (Please, use the Jargon
file next time you look something up in the dictionary, geez) is
software which is not licensed under a Free Software license.  This
includes Java *as implemented by Sun* but NOT DTML or Free
implementations of XML.

Well, the issue is not really "the language".  The issue is whatever
software implements it.  Anybody can implement DTML, or Java, or XML,
or whatever, and license it however they want.  The question is,
whether this implementation is Free Software, and indeed, it is.

Interesting point.  I myself prefer Perl to Python for a number of

Untrue. Apache's load/stats and Zope's load/stats are different sides of
different coins.

You're implying that Zope has no statistics to export, and that if you
couple Zope with Apache (which you might not want to) then the numbers
that Apache can export would apply to Zope -- and this is clearly wrong.

Thank you for completely sidetracking me and instead choosing a flame
angle for petty word games.

My point specifically was that the mass of mainstream appreciation of
Zope versus a product like Dynamo was specificially _not_ related to
openness. IBM does not open its money floodgates to invest in Linux
merely because Linux is an open technology -- Linux was not the first,
nor the last, not arguably the finest open technology in the history of
IT. It and others do so, and give momentum to Linux, because of money,
pure and simple.

Let me relate a short anecdote for you, about the incident which
triggered this thread. See, my colleagues are currently involved in a
large project for a large company. They are buying Solaris 8 to run
Dynamo. I've made a very strong case for Linux and Zope.

There is, today, only a marginal difference between these two setups,
and that difference is in price: The Linux/Zope combo is significantly
cheaper than the Solaris/Dynamo combo. This has zero bearing upon their
choice, and indeed on most ordinary computer investments for any
company: The cost of buying a computer and licensing the software is
"nothing" compared the maintenance costs and the insurance a big company
needs that their investment is safe. In other words, heavy support plans
and brand names.

And guess what? Despite the fact that both Linux vendors and Digital
Creations offer such support plans, my advice to my colleague and this
company falls dead on the ground.

Zope doesn't have the flashy packaging and sexiness of a product line
Dynamo -- which, actually, I strongly urge you (and everybody else in
this forum) to experience yourself, before you snap back at my again --
and this affects management decisions. Dynamo is exceedingly sexy, and
it boasts the kind of bullshit magic that have management and tech
people alike drooling.

So is it "their problem"? In the end, I don't think so. I think they're
going to be quite happy with Dynamo.

As one of my colleagues pointed out, the problem starts with the name.
(Somebody out there is hyping what they call Linux' next-generating GUI.
And it's called... GNOME. What's wrong with this picture?) I don't care
myself, but I recognize the problem.

I don't claim to be an OO master or a ZOPE master, but I'll give this
a shot anyway and share some recent revelations I have had about OO in
general.

First off, the examples that people always use to demonstrate OO
concepts wind up being more distracting than they are worth.  For
instance modeling a can of spam in OO.  That would be a logical thing
to do, if you were writing a control program for a can of spam.  But
NOT if you were writing a database app!  This, I think is one of the
most confusing parts for database programmers coming to OO.

Second, so if you don't model your can of spam, then what DO you
model?  Well, you model *your data* and if your data is a database,
then that's what you model!  Soo, you create an object of type
"Products_Table" which contains methods to operate on the entire
table.  Then you create objects of types "Products" which contain
methods to operate on the objects.  But since your products can be
many different kinds, you don't "hard code" what kind of product they
are, you just make a generic object that contains generic functions.
If you wind up needing to do something special for a particular
product, *then* you create a subclass of product for that kind of
product that you can use for that.  Ie:  "Delicate_Product" might be a
subclass of "Product" that might have a special some special methods
for dealing with products of that type.  Something like "find" should
be a method of the table that returns an instance of your product.

So, your loop becomes something like this (pseudo code that looks like
c++?):

while(sData = Input.Read())
{
	MyProduct = new Product(sData); // object init's itself
	if(MyProduct.Validate())
	{
		MyProduct.Write(Table);
	}
	delete MyProduct;
}

Is there a way to upload more than one file or image at once?  It seems very
cumbersome.

Hmm.. are you sure you are starting Zope as a priviliged user, like root?
Zope can only bind to port 80 if started as a priviliged user (it will not
run as a priviliged user, rather, it will, by default, switch to 'nobody').

The permission denied error is clear pointer in this direction.

Lynx does frames just fine. It lists them as hyperlinks. Just select the
second one, and you'll be amazed how much you can do with Lynx and Zope =)

This is because:

1/ MailHost doesn't integrate into the transaction mechanism all that well
(patches accepted =))

2/ Email is inherintly an unreliabale form of data transport.

Hi. How's Jim getting on with this? Apologies if I missed something

Hi everybody,

although this may have been discussed several times:

I added a multiple property to a class, but when I call the instance's
property sheet from the management interface, I get an Type Error,
whenever I did not chose anything from the selection box. That is of
course ok, because there is no property defined within the instance if I
did not select anything. (getProperty(id) fails on None)
How do I create an "empty selection"?

Thanks for your help

BTW: <dtml-call "REQUEST.set('x','[]')"> did not work.

He has checked in the fix - if you are tracking CVS you need to 
update lib/python/ZODB/TimeStamp.c and rebuild it. For those not
using CVS, I've attached a copy of the updated file to this email 
(but you'll still have to rebuild the extension for the change to 
take effect).

It is definitively not a good idea to rely on browser detection
for you pages. Especially if you dont already know how to do it.
Try to make your HTML-code not so special to let it work for all
browsers (you cant know how to handle the specific of all the
browsers available).
But, if you really cant live without it (please overthing it more
than twice!)
REQUEST['HTTP_USER_AGENT'] is your friend, together with various
string-operations.
Please note: you cant be sure if this field is set and tells you the
truth about the partcular user-agent.

Message-ID: <m31z5mmy4y.fsf@wacko.pdx.net>

If I have a ZClass with a property sheet called 'Info', how can I get
access to the sheet when I DON'T have an instance of that ZClass to
work with.

Specifically, I want an ADD form for my ZClass that has an ID field
and a dynamically generated section containing all the properties from
'Info' all on ONE from.  I can't seem to figure out how to dynamically
generate the property section without an instance to work with.

Actually the guys at Spam inc. IT do model Spam cans (how about the lot 
numbers in case of botulism or something?) I believe the reference to 
Spam
was just an example though ;-)

More likely I would write a Class called "Table" that knows about 
accessing all 
relational database tables not just "Products" (see Data Adapters in 
Zope)

Would you have a different table for this?  This is a debatable topic -
if you don't have different attributes for your subclass then, it is 
argued,
you don't really need that subclass. Special methods for this can be 
done
as you propose or just tested for in one class.  The reason this is 
important
here (in this discussion) has to do with oo-relational mismatch or 
impedance.
When you are bringing back your objects from the database you are going 
to have
to know which object to "instantiate" (this term is used losely here). 
This means 
special handling for your queries. Or you can pay the pain by having 
two tables which
makes your queries for all objects harder. As you can see it isn't 
necessarily simple.

There are several ways actually --

This would translate to a "Stock" object with three attributes
as you have stated below -

Yes this is still olde kinderhook.

For me this method would be an instance method, each instance would 
have it called upon itself.

Actually you are correct. There will be an input program. You won't see 
much
difference between OO and your conventional database way (if you will 
allow me
to assign that term here). The reason is we haven't actually done 
anything
too significant yet.

Using my assumptions and examples from above I would have the Stock 
class
ask my table class to build a SQL query to do this

As above have the Stock Class have the table class find all "rows" which
meet this criteria then for each instance send updatePriceBy(2)
where the 2 is an argument and since it is positive the instance of 
stock
will add 2% to its own price

Here comes more spin though I'm afraid (sorry :-P)

Up til now I've left out alot of the mechanics.
The Table Object knows how to form SQL queries which gets you subsets
of your objects (not just rows of data) It in effect provides the code:

   product_1 = Stock(product_code="ABC",Description="Spluggifier", 
Price-"20.00")

only instead of product_1 it would be 'next_row' or 'this_row' 
(depending
on how you like to think of database cursors). Also somewhere there is 
a mapping between
the Table and the Class it represents. This allows the Table to become 
a Class,
the row to become an instance, and the columns to be attributes. These 
mappings
would be plugged into the above code also (i.e. product_code becomes 
attributes[1])

This mapping solution is a common pattern - IDL to Corba, DTD to XML in 
generic terms.
Here we start to see OO work. I defined my class and map it to 
different things
such as Corba or XML - now I can ship the object flattened as a string 
(or some other
form) and a reciever can inflate it back. This would be the user input 
form. This flattening has a special name in ZODB (as far as I can tell) 
it's "pickling"

Hope this doesn't add more head spin. There is much more to this story, 
we haven't
even talked about, such as foreign keys and how to map them to Objects. 
 

As far as modeling the data, I don't model a database, just the data, 
but it also
depends on if you are supporting a previously existing database or 
starting new.  I have done both and it is a black art. You have to 
support management, other departments etc without tipping the boat 
over, so you generally follow the flow. But for the most part you want 
to analyze the problem domain from an object point of view from the 
start. This gives you important insights to other parts of the problem 
such business processes and object interactions you didn't know about. 
OO is not just an elaborate ERD (Entity Relationship Diagram) But it is 
the most common place to start. This is just one way to do it, not 
necessarily the "Right" way, (if there is such a thing)

Hope this Helps

Other people answered your conversion question, I just wanted to point
out that the ':int' notation is meant for use in qualifying HTTP POSTED
data, like that coming from a form.  For example:

<form>
  <input name="bob:int">
</form>

This will cause ZPublisher to try and turn the value of this element
into an integer.  This is the only place the ':int' notation makes any
sense.  In your example, you have confused this notation with that of
the let tag.

Please post a traceback with your error (look in the HTML source of the

Instead of going to http://blah/Object/manage go to

Voila.  If you want to see the left hand tree frame go to /manage_menu.
It many not look all that pretty on lynx, but it works fine and I use it

Subject: [Zope] Property Sheet Question
Message-ID: <4.2.2.20000307143411.00b56800@saladin.aisys.com>

I'm defining a property sheet for a new ZClass object.  I want to define a 
property which is collection of items (in my current case it's strings, but 
conceptually it could be something else).  When a new instance is created 
(or edited), I want the user to be able to specify 0 or more items.  Is 
there a property type which supports this?  What, for example, are "lists" 
and "tokens" and how do you make use of them?  In the particular case that 
I'm working on, I want a user to be able to enter one or more e-mail 
addresses and one or more urls.  At some point I will want to iterate over 
the e-mail addresses, or iterate over the urls when I construct a view for 
this object.

Any tips or insights on this subject would be appreciated.

Thanks.

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Message-ID: <38C55EE7.36417628@digicool.com>

There is no standard rythem for manipulating the class without an
instance.  At least not that I know of.  It can be done, however,
because it can be done from the managment interface.  Anything that you
can do with clicks in a browser you can do with DTML, it's just in this
case your problem is necessarily complex because we never, ever,
considered your use case when we engineered ZClasses.  This is one of
the reasons why software can be dificult to use, because the engineers
did not KNOW in advance how you wanted to use it.

But you want to do this so I suggest you look at how the managment
interface traverses through the Control Panel and Products to manipulate
ZClasses. Using URL introspection, you should be able to deduce how to
do this.  I would help you but I honestly don't know how it would be
done myself.

I use IE5 on Win98 and NS4.7 on an old LinuxPPC box. No problems here with
Netscape running away though, I leave it running days at a time.

Netscape on NT/98 frequently runs into authentication problems with our Zope
install (using mod_proxy and ZServer) and sits there flickering the status
bar forever, whereas IE5 doesn't do that, it pops up the password dialog
when confused. IE does occasionally crash in the management screens (never
any other time), and I can't figure out why.

the path. In other words I would like to be able to have a user
interface which would allow a person, with an export role, to be able to
enter a
list of fully qualified Items to be exported.

Consider:

FolderA
        FolderB
                ItemToExport

I can export ItemToExport from FolderA by calling:

<dtml-with "FolderA.FolderB">
        <dtml-call "manage_exportObject(id='ItemToExport')">
</dtml-with>




but I don't want the FolderA.FolderB to be hard coded. I would like it
to be a var that I pass into the method. Something like:

<dtml-with FullPath>

what should the syntax be. 

Thanks,

OK, but see you're trying to make Linux something it is not.  Linux is
not about marketing.  It is not about world domination.  We
specifically do not care about this :-)  Now, digicool is a company,
and they probably DO care about this.  Making Zope Free Software is a
great way for them -- and us -- to benefit.  So your comments should
be addressed at them if you want them to make the sale.  Not me, a
Linux hacker.

But see again, Free Software is not about marketing.  The name is
irrelevant to us.  Free Software is about what's *right* and what
*works*.  We leave the marketing to those that want to do it (such as
digital creations, or whomever else).  So again, write to digital
creations' marketing dept. :-)

have you figured out a way to move through the ZODB for a certain type of
object?  and then manipulate it in the way you need?  I'm having this same
concern from a project right now -- they are scared to put content in ZOPE
because if we move to another content manager- we may not be able to get the
data out (please point me to info). 

your secondary question is just as valid:  versioning lingo in zope is not
versioning as in source versioning but a 'temporary lock' on files.  things
look differently in/outside of versions.  thats versioning now.  how about
retaining 'versions' of a website (I think vignette does this) - so I can
call (if I had diskspace and *WANTED* to) my website and say, "what did the
frontpage look like last month?, last week?, two days ago?" <- anyone worked
with this, because this is what is typically referred to as 'versioning' (I
believe).

Thirded. I discussed starting somekind of Zope-XML SIG with Amos Latteier
and generally he's favorable to this, but how do we start? We need a mailing

Thanks.

What had me confused is that

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
<dtml-var Currentdate>

and

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">
<dtml-var Currentdate>

both display the same date string whereas I guess the latter should
display an error.  It only reports an error when I try to do something
else with the variable.

Hm, skilled developers do hack on Python! There's the Python people at
CRNI, there's Christian Tismer in Germany doing Stackless Python (which
offers interesting arcane features and a mild performance improvements),
there's the whole JPython group, there's John Skaller with his Vyper
project (a Python interpreter/compiler in Ocaml, one of the reasons
is more speed). Then there's the Python Types-SIG, which I urge you to
look at if you haven't already.

It is _less_ of a problem, but most Pythoneers are indeed interested in
speeding of the language. I haven't heard of zealots who want to hold
back speedups, as long as it doesn't do away with the power.

It'll be pretty difficult to make a beast like Zope exploit type-hints, though,
I think. By the way, the Types-SIG is working on type extensions to Python,
partially for performance (OPT), partially for better error checking (ERR)
and partially for better documentation (DOC). See:

http://www.python.org/sigs/types-sig/

And also see the new compiler SIG:

Type inference is not a simple thing to add to the language, though..

That's of course true. I heard Christian Tismer talk about making a 
register machine interpreter for Python, which could potentially speed
things up quite a bit. I shall ask him about this idea again sometime. :)

All true. Anyway, the only thing you're wrong about is that Pythoneers aren't
interested in improving performance. They are, but I grant you they're not
performance nuts like users of C or C++. :)

Ask Linus Torvalds. :) Anyway, Linux is what people do with it. Not what
people say about it.

I care about making Zope more popular, as there will be more Zope users,
more Zope hackers, and better free Zope support. More cool Zope goodies.
More Zope related jobs. I care about Zope marketing.

Even if you only care about Free software, you care about marketing it,
as you care about what's 'right', and therefore you want people to use
the right stuff; Free software. Right? :)

Alexander Staubo obviously was interested in Zope marketing. Why tell him
'we' don't do that, while some of us are definitely interested?
Free software is about people doing what they want. Let us do want they
want and don't speak for me. :) Thanks.

This is just a guess (I'm a Zope newbie too) but I believe

<dtml-return "['John\'s', 'Mary\'s']">

Will work.

In the second case, I guess <dtml-var CurrentDate> is recognizing that
CurrentDate is a reference to a function and calling it.

I understand, now, how that had you confused. Anyway, glad it's working!

These are what you want. In the case of tokens, it will separate each word
into a list element. A "lines" property separates each line into a list
element.

Tokens: 'foo bar baz' = ['foo', 'bar', 'baz']
Lines:
foo bar
bar
baz

Becomes: ['foo bar', 'bar', 'baz']

This should work fine using standard <dtml-in>s, since tokens and lines are
sequences.

The kernel internals of Linux use a 32 bit off_t, hence discussion of

Granted, that's a sparse file (I can't afford that much disk space :^),
but it demonstrates that file offsets are not a problem.  As mentioned,
NetBSD's off_t has been a 64 bit type for about 6 years now, even on
i386 (and evey other platform).  In fact, off_t was made 64 bit in 1994,
and NetBSD/alpha didn't exist until 1995, so it was done before there
were any native 64 bit platforms supported.  :-)

However, it turns out that for Zope use, at least with FileStorage,
there is a problem, which turns out to be even an x86 issue but a silly
ANSI C spec issue.  Unfortunaly Python large file support is broken on
(32-bit CPU) NetBSD as a result -- I had to make that sparse file with a
little C program.  Now, you could have a more than 4G BerkeleyStorage
Zope system, since the file handling isn't done at the Python level in
that case, but FileStorage won't work until I can work around the Python
problem (or until NetBSD 1.5, which will fix it in a different way). 

But at least it's the kind of thing that could be hacked around in an
application by one guy in a day, rather than taking drastic kernel
and libc changes :-)

What version of Zope is this?  A recent bug fix has been checked into
the pack function and my line numbers don't corespond with yours.  I
need to know what version of Zope you are using so that I can get the

Packing does not modify your existing database file until it completely
succeeds.  During the pack, packed data is written to a temporary file
and your main file is just read from.

FYI, you are searching for the union of two search terms, 'ZODB' and
'troubleshooting' which is why you got more for the second query than
for the first.  To explicitly get an intersection, say 'ZODB AND
troubleshooting'.

That bring you back a much smaller number (0).

One place to start might be to join the Python XML SIG. It has a high
S/N and most of the discussion is probably relevant to the Zope XML
effort.

It would provide the benefit of knowing what's currently available from
AMK, Four Thought, etc., which might be reusable for Zope.

Four Thought's 4DOM, 4XSLT, 4XPath are getting pretty mature, with 4ODS
and 4XLink in the wings.

Additionally, if you haven't the bandwidth (I certainly don't) to
follow the xml-dev newsgroup, the XML SIG gives you a filtered view of
all the mighty standards power struggles going on as we speak in the XML
world, so you can have some perspective on the right time to jump on the
Schema train and so forth.

Thanks.
We will eventually be looking into optimisations for the list command,
to
reduce the depth of braches traversed. If any UW IMAP users can confirm
which flags represent what in that context, that would be helpful. Then
we
could avoid listing them.

Yes, I did get the following response from Drew:

--- snip ---

The easiest way to make changes to all of your SQL methods would be to
export your entire Data.fs into XML format -- then use your magic       
text editing software tools.

With respect to version control and configuration management, I have
used the same XML export format and checked this into CVS. Of course,         
I feel that XML is human readable... YMMV.

--- snip ---

I agree with this basically, and I can see this as a partial
solution.  Basically, if you were using this in production, you would
want to schedule a script to automatically pull out the XML export
from your site say, once a day, and check it into CVS.  Depending on
your needs and your ambition, you could probably go so far as to go
into particular folders and pull out peices of the site individually
and check those in seperately, that way you could look at "Show me all
objects that have changed since April 10th" or whatever via CVS.  This
would also allow you to rollback to a previous version (ala Software
Configuration Management type stuff) by checking out all peices to a
system from CVS and then importing them back into Zope.  Kinda a
hassle compared to how CVS automates other development environments,
but then, other development environments aren't quite web RADs
either.  At least you CAN export and import the data as XML.  A
similar situation arises with tools like Delphi etc where your forms
are binary files and you can't make global changes to them except via
point and drool^H^H^H^H^Hclick.

Note: I refer to scripting exporting.  At this time, there's no tool I
know of to do this.  You would need to do this yourself.  SO... if
there's anyone out there who is a wiz with the ZODB that could MAKE a
tool to pull this stuff out.  I'd appreciate it.  If it was me, I'd
just script something to pull it through the web interface, but a
non-web oriented, just run on the ZODB tool would be better.

Message-ID: <200003080133.UAA14797@saltmine.radix.net>

Ok, I've gotten pretty far with Zope this time.  But (of course), I've
got a bunch of questions.  Starting with...

1)  What is the algorithm for determining which method to call?  The
    DTML documentation says

  "attributes, including inherited and
   acquired attributes, of the client passed 
   in the call to the document template are searched"

   But in what order?   There can be an index_html in the class, in a parent
   class, or somewhere up the acquisition tree.  Which takes precedence?
   Does the product that a ZClass have anything to do with the search?
   What about Z-Super-Classes?  Inquiring minds want to know.

1a) Why can't I have a method in a ZClass, but then override it in
   the instance?  I.E. (Gaak, it has been a while since I've had to
   even think about C++) virtual methods?  (Or have I got that wrong).

2) It seems that the examples require the user to generate forms by
   hand, which seems unnecessary.  For example, (after a protracted
   struggle with the underlying python code) I wrote a method that would
   create an html table for any query, ripping the column names and data
   out of the result object.

   2.1) Shouldn't this be a standard part of Zope?
   2.2) If so, do you want this code?
   2.2) Likewise for property edit forms.  I did find some DTML that
        would do this, but shouldn't this be standard.

3) Anyone want to help me whip snmpy into shape and create soem
   nice Zope classes for accessing SNMP variables and tables in routers
   and such?  

Enough for now...

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time.  I get the following log

I would have to research this to give a precise answer. Basically, it all
depends on the current contents of the namespace stack. Generally, this
will search REQUEST first. Next, we look to the object containing the
method being rendered. Then, the object containing that object, etc.
Whenever a ZClass is queried for an attribute and doesn't have it, it
looks to its parent(s).

I made this mistake when first working with ZClasses, too. If you think
about it a little, you'll realize that, virtual or not, you cannot
customize an OBJECT in C++, only a CLASS. i.e.:

---
class A
{
public:
  int x;

public:
  A() { x = 0; }
};

class B : public A
{
public:
  int y;

public:
  B() { y = 0; }
};

A* objectA = new A();
B* objectB = new B();

objectA->x = 1; // Valid
objectB->y = 2; // Valid
objectA->y = 2; // Invalid, because class A has no such attribute.
objectB->z = 3; // Invalid, because class B has no such attribute.
---

If you want to customize an object (instance), you have to extend its
class, first.

In Python, this is not (really) true. Any old object is a dictionary, so
yuo can add attributes to it on the fly. Thus, the question, how can we do
this with ZClasses?

I wrote a base class that overloads ObjectManager's _checkId method to
allow instances of a ZClass to be customized. It looks like this:

---
from OFS.ObjectManager import bad_id

class Overridable:
    def _checkId(self, id, allow_dup = 0):
        if not id:
            raise 'Bad Request', 'No id was specified'

        if bad_id(id) != -1:
            raise 'Bad Request', (
                'The id %s contains characters illegal in URLs' % id)

        if id[0] == '_':
            raise 'Bad Request', (
                'The id %s is invalid - it begins with an underscore' %
id)

        if not allow_dup:
            if hasattr(self, 'aq_base'):
                self = self.aq_base
            if self.__dict__.has_key(id):
                raise 'Bad Request', (
                    'The id %s is invalid - it is already in use' % id)
---

This is not foolproof (it allows you to override TOO much, i.e. you can
create a method with the same name as a property), but it shows the idea.
I just subclass my ZClasses from this class, and I can customize each
instance individually.

I am now able to use the GUF the way I want to. I changed the POSTing

the original variable that was there, didn't work at all). I created a
dummy dtml doc called dud, pointed my POST to it, and I authenticated

Thanks a lot Ty for the detailed reply. Mostly for clarifying a few of
the stuff you were talking about at IPC. Seems to me that at least some of
the major components of Zope should be designed in this manner, but on the
other hand it is only after one codes a few specific situations that the
general pattern emerges.

Subject: [Zope] index_html for root
Message-ID: <001201bf88c0$8ad24e40$770da8c0@bbs>

The attached file is intended to replace the current architecture of header
body footer of current zope default index_html.

Together there will be some attributes which can be used to modify its
behaviors :

wap - when defined, set the content-type in RESPONSE accordingly according
to Ducan's WAP howto. and sent out the <wml></wml> tag.

xml - when defined, set the content-type to xml/plaintext and the xml header

frame - when defined, prevent sent out the body tag

Only one of the above can be set. I still got problem with acquisition: if
one of these is set in a higher lever, then all lowerlevel see it. Are there
any easy way to set them off?

doctype - when defined, should contain the correct doctype string: currently
the following doctype is available:

    html4.0
    htmlstrict4.0
    htmltransistional4.0
    htmlstrict4.01
    htmltransitional4.01
    htmlframe4.0
    htmlframe4.01
    xml1.0
    xhtml1.0

The following is defined inside the index_html:

dtml-head - the content of the <head></head> section
dtml-headers - the content of contructs before the main body: This should
not left any tag open.
dtml-footers - the closing contents of the main body. There should not
assume any opening tags.

index_htm - the main content. a frameset statement if frame is defined. If
the main content contains a table, then the main table is defined here, the
parts in the table can then be dtml-var. A index1 index2   .... or indexr1c1
index r1c2 .... naming convention is suggested.

I strongly suggest convert the current zope sites to adapt to this style
through much works shall be needed.

Further work would be in the dtm-head: Recently I will suggest to adapt the
W3C core styles : http://www.w3.org/StyleSheets/Core/Overview

All suggestion and comments are welcome.

Message-ID: <NDBBLBELNHAPHBBCOIFDGEHLCBAA.ewalstad@energywright.com>

Hi David and the rest of the group,

Can you believe I am still battling this MySQLDA installation!?  ARGH!

I hope you can help me out here:

According to the HOWTO by alanpog, I've
1. Downloaded MySQLDA 1.1.3
2. Expanded it into my top level Zope Directory (/usr/local/Zope) Note that
I did not do any installation here, just expanded it into this directory.
3. Downloaded MySQLdb v0.1.2
4. Expanded MySQLdb into /usr/local/Zope/lib/python/Products
4a. Modified the Setup.in file so that the one uncommented line is:
    _mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt
    As you mentioned, these point to where my MySQL libraries are.
4b. According to the README file, ran 'python build.py'
This is where I am stuck.  The build.py script crunches along then bombs
with the following error:

Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I checked and this file is in my /usr/local/lib/mysql directory.  It is a
link to libmysqlclient.so.6.0.0.  Both files are there; owner=root,
group=root.

I'm hoping this is a simple fix ;^)

Any idea's would be greatly appreciated!

Eric.

>Is there a HOW-TO or other documentation that shows how to set up a login

>advance for any help/pointers provided.

I don't know if there is a how-to but the way I do this is very
simple. I have a simple form with only a submit button with name login
(it appears on a sidebar of the web site).  When it is clicked it
posts to the current URL.

<dtml-if isRegistered>
You are 
<dtml-in "AUTHENTICATED_USER.getRoles()">
<dtml-var sequence-item> 
</dtml-in>
<b><dtml-var "AUTHENTICATED_USER.getUserName()"></b>
<dtml-else>
<FORM ACTION="<dtml-var baseURL>" METHOD="POST">
<INPUT NAME="logon" TYPE="SUBMIT" VALUE="Logon">
</form>
</dtml-if>

In the start of every page I call a method to check for 'login' in the
REQUEST variable. If it exists I calls or references an empty method
which anonymous users have no rights to but which authenticated users
do have access to (with ID login in this example.

<dtml-if "REQUEST.has_key('logon')"><dtml-var logon></dtml-if>
<dtml-call "REQUEST.set('isRegistered',AUTHENTICATED_USER.has_role(['Staff','Student','Manager']))">

Zope will therefore invoke the authentication mechanism which means
the browser will ask for a login a password as usual. From there on
the user will have been authenticated and you can check their name and
what role(s) they have in the current context. 

As you can see once with the code given here the user has logged in
instead of a login button they will see a message giving their
username and global role(s).

Hope this helps.

I am making a new head zope index_html file, I think it is now about time to
make use of the HTTP_ACCEPT_LANGUAGE which is sent by the browser to
indicate the perferred language.

The variable is a string like:

lang1, lang2;q=p1,lang3;q=p2....

while lang1, lang2, lang3 is the perferenced languages.

I have think of the following ways to make such brenches in zope:

1. by setting the lang variable in the REQUEST
2. by transfer to the brench of lang/
3. brench calls of index_lang

What will be the perferred way to make such a brench? I want to hear from
all.

In building the brench code : I have come up with the code:

<dtml-in "_.string.split(HTTP_ACCEPT_LANGUAGE, ',')">
   .....do thing according to sequence-item
</dtml-in>

but on the second argument, the sequence-item may contain ;q=0.5 which need
to be trancated. How can I trancated that in dtml?

It's quite nice being able to edit the site using Lynx,
but you cannot create new objects as the 'Add' option
box uses Javascript. Because it's listed as DISABLED,
Lynx won't let you pick a type before clicking on Add.

move to the new style <dtml- from <--# tags.

I'm also waiting for someone to write the "dtml-method beautifier".  :)

I played around with nedit's syntax-hiliting so it recognizes dtml as
opposed to regular html.  Not perfect, but better than nothing.  Plus I
improved the python mode a bit.  If any one wants it email me.

Nope.  There may be some standard python library module that I don't
know about, however.  Otherwise, you will have to write your own.

The first two follow standard python rules, first instance attributes,
then shared instance (class) attributes, then any base class
attributes.  THEN acquisition.

No.

Same rules.  First the instance of the ZClass attributes, then shared
instance (ZClass) attributes, then any base (Z)Class attributes.  THEN
Acquisition.

I think your confused but I'm not sure.  If your ZClass is a container
(subclasses ObjectManager) then instances of that class can contain
sub-objects (attributes) with names that are managable by the Zope
managment interface.  The managment interface will NOT however let you
create a sub-object in that container that conflicts with the name of an
existing attribute *including shared instance attributes like methods of
YOUR ZClass*.  Methods of a ZClass may look like sub-objects in a
container instance, but that are not, they are shared attributes of a
class, and all instances of that class will share those attributes. 
Now, this is a limitation/feature of the managment interface, it is not
a limitation of python.  If you want to assign an attribute to an
instance in python that has the same name as a shared instance
attribute, then that instance attribute will override the shared
instance attribute.

Ok.  You're talking about SQL Methods?

If you're talking about SQL Methods or other objects that implement the
Zope Search Inteface then it is allready a standard part of Zope.

You should look at what is there first and tell us how to improve it.

The managment interface obviously builds the property view dynamicly, so
something like this is in Zope.  Whether or not it is useful to others
is unknown to me.

Right, this is certainly a good place to go to as well. But Zope has its
own rather different requirements, and I think we need a seperate place
to discuss adapting all these technologies so they'll work with Zope -- 
the people in the Python XML-SIG might not care about Zope.

Also, the Zope XML list should also be the place where people ask *questions*
on using Zope with XML; this way we learn more about what people want and
what problems they may be having. And that way we can improve Zope's 
XML support. The Python XML-SIG wouldn't be the right place for that.

Okay, I was considering joining that SIG anyway, but I don't think it's
enough for developing Zope's XML support.

I would say that I specifically do care about this. As a freelance 
developer I want there to be good recognition of Zope in the market place. 
It is all about recognition. I was extolling the virtues of Zope to the IT 
Director at a client and he said 'So why haven't I heard of Zope ?'. My 
answer, that it was all very new and on the verge of success probably did 
not convince him. (Of course it is all very new and it is on the verge of 
success ).

If I say Linux, Perl or C then management are usually quite happy. These 
are recognised names - but nobody owns them. SO it is possible for free 
software to be successful in the sense that they are as well recognised as 
commercial products (which have huge budgets behind them).

Some management (perhaps most) will prefer to buy a "fully supported" 
product from a major player. We don't need to take on that kind of 
marketing head on. Rather we can present Zope and Python as tools to do a 
job, not strategic decisions to be made by management. However it is 
reasonable for management to ask "Will Zope be around in three years" - 
"can we de-Zope if we have to" - "Who owns Zope" "Who uses Zope". Managers 
are not likely to take a "risk" on a product. At the moment they usually 
feel happy that Linux, C and Perl are going to be around in three years time.

If Zope is to succeed it will be because of its capabilities as a product - 
because it installs out of the box in six minutes, while the Microsoft 
equivalent takes 5 hours. Because 60 minutes after downloading it you can 
be running a web page which interrogates your legacy databases (which is 
what happened to me).

We know about the documentation issue, which is hopefully being sorted.

I feel there is also an issue with the product itself. Zope seems to work 
on two levels - you have a very high-level part - I'm thinking of the 
security model, the SQL methods and the Z Search interface, the drop-in 
products like SquishDot etc. These set Zope apart from other technologies 
which people might use (PHP/ASP etc).

You also have a low-level  part (External methods etc). Because Zope has 
the high level part it encourages the thought that there is not much 
'programming' needed to develop a Zope site. But sooner or later you are 
going to hit a wall - for example questions you see asked on this list such 
as "how do I assign a value to a variable". Well the answer is ...

<dtml-call expr="REQUEST.set('abc_search', strip_abc(abc_text))">

... a string of gobbledygook. (So what does the dtml-let tag do is the 
obvious question that springs to mind.)

It is great that Zope has the low level stuff but I feel that work needs to 
be done

1) To analyse actual usage of Zope to see what features are being used and 
which areas of usage cause concern/difficulty
2) To Implement high level dtml tags to implement them.

I've stuck my neck out here - feel free to chop it off.

How do I call the stored procedures written in Oracle from
"Add a SQL Method" interface, especially when there are OUT parameters

but there seems to be a missing step ahead.

Assume the scenario:

Oracle Procedure: myProc(para1 IN  VARCHAR2,

What should I put in the "Arguments" box and "Query template" box? 
And how do I retrieve the returned arguments in the following dtml

Yes. Alexander has brought up a very (IMO) relevant issue. It is in the
interest of the entire community to make Zope well known and I feel marketing
should not be left just for DC to take care of.

I see a number of articles/sites about 'app servers' which don't mention Zope
but mention others (including some mickey mouse servers I've never heard of).
Eg: http://serverwatch.internet.com/appservers.html
Why? Maybe Zope isn't talked about at all outside some circles?

Altavista shows about 1058 pages linking to zope.org (compare php.net:12,000 ;
apache.org:60,000). Why?

If nobody does anything, this will take time to change. If we want this to
change faster, all of us have to actively market Zope. This involves talking
about in appropriate newsgrousps, putting up zope webpages,
making Zope easier to learn and use, adding flashy features etc.
All this can make a whole lot of difference.

Still it would be sensible to do it by splitting the database file (say at
1M boundaries rather than supporting some obscure non-standard system calls 
that only few platforms support. Probably also one-day hack by someone 
who knows where to start digging.

At least this is how it was solved for PostgreSQL .

Subject: [Zope] getting object reference from an id string?
Message-ID: <001001bf88f9$4b84eca0$a1ac8ec6@hikari.anu.edu.au>

Say one has an object reference and knows the
string id of a child node.  From this info, we
want an object reference to the named child.

I'd like someone to prove me wrong that there
is not a one-liner to accomplish this seemingly
trivial task.  I've had to resort to (off the
top of my head) code like:

<dtml-in "objectValues(['child meta-type'])">
   <dtml-with sequence-item>
      <dtml-if "id == desired_id">
          <dtml-call "REQUEST.set('desired_ref',_['sequence-item'])">
      </dtml-if>
   </dtml-with>
</dtml-in>

I'm really looking for a solution that doesn't
require looping.  Since Zope enforces unique id's
at a given level, the name should be sufficient
to resolve the child object.

Darran.

just use 'reverse'

like this :

<dtml-in "objectValues(_['sequence-item'])" sort=bobobase_modification_time reverse size=3 orphan=0>

   It is hust plain "reverse".

   I wouldn't buy your idea of easy splitting Data.fs. Exactly like with
the VACUUM, packing Data.fs would be complex task if the data will be

The claim of "a days hacking" was meant as an ironic counterclaim to it being 
a day's job on *BSD

I would suggest it by implementing a file-like HugeSplitFile class and 
using that to hide all the splitting from all other layers. 

If we could implement it in python then it would be perhaps a 1-hour job, 
leaving the rest of the day for fixing up the parts of zope interfacing 
with it ;)

It would probably consist mostly of adding long() to some initialisation 
functions.

   This is a record object. You should use:

On the other hand, if you tell the user up front that HTML tags are not
allowed, you can simply html_quote the text.  That will prevent any tags
from rendering, and prevent normal uses of '<>&' characters from breaking
anything.

Subject: [Zope] Performance and Concurrency
Message-ID: <200003081355.IAA06034@saltmine.radix.net>

I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute).

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

Or, use something like w3m

to take the html and turn it into plaintext.
Pop it into an external method something like the following, and it should
do the trick:

---html2msg.py

from popen2 import popen2
def html2msg(htmlstring):
  try:

    (r, w) = popen2('/usr/local/bin/w3m -dump -S -cols 70 -T "text/html"')
 
    w.write(htmlstring)
    w.close()
  
    s = r.read()
    r.close()

    return s
    
  except:
  
    return 'Error converting article to plaintext.'

It's an ugly hack, and you lose things like <br> and <p>, so you may want to
replace \n with <br> afterwards. It does, however, do a brilliant job
layout-wise: tables and lists remain fairly well formatted, for example.

Sorry, I wasn't clear.  What I was looking for was a method to get,
for example, an html table out of what an ZSQL method returns.  I
had to look at the code under lib/python/Shared/DC/ZRDB to figure
out that calling a ZSQL Method returns a Results object, and then
look at the results object to see that it has methods like names(),
data_dictionary() and tuples().  Then I could write a loop like...

    <dtml-with "Your-query-method(parameter=value, parameter=value)">
    <table border=1>
      <tr>
        <dtml-in "names()">
          <th><dtml-var sequence-item capitalize spacify></th>
        </dtml-in>
      </tr>
      <dtml-in "tuples()">
      <tr>
        <dtml-in sequence-item>
    	<td><dtml-var sequence-item></td>
        </dtml-in>
      </tr>
      </dtml-in>
    </table>
    </dtml-with>

My point, I guess, is to suggest that this should be a built-in method
in a ZSQL query.   Unfortunately this would also hard-code the
appearance of the table unless it had lots of options.

I'm probably missing something.

I did find code that kind of did this in the manage_test method in the
ZRDB/DA.py file, but when called returns manage_tabs, and also access
some non-dtml-accessible functions like result._serachable_result_columns().

I'm sure I'm missing something, but this doesn't seem accessible from DTML.

Once again, there is code to render property table forms, but it is 
buried inside lib/python/OFS/properties.dtml.  Once again, it seems
as if a standard method to generate a form for editing properties
would simplify creating applications by eliminating the need to
type in, by hand, the required forms.

I've seen a couple of pieces of code, both in the mailing list and
on zope.org to do this.  

The overall goal is to make it easier for beginners to whip up an
application without having to know too much about html forms and
formatting.  Plus to make the system easier to maintain by not having
redundant information (i.e. in the property sheet or query, and also
in the DTML that renders it).

Thanks for your time...

In my ongoing efforts to gain a bit of recognition for the capacity of
Zope, Python,  and all things Open Source, it looks to me as if Marketing
Matters, regardless of my wishes. Even if, to me, the validity of Zope /
Python is "obvious", it is not so clear to others, and especially others
who make decisions about tool selection. 

At some point, if Zope / Python is to find a place in the larger world,
these folks must be convinced. There may be a more palatable word, call it
"education", "concsiousness raising", or some other more trendy phrase.
Still, you can get the gist from the words, "selling", "marketing", or even
"hype".

Check out some of the articles by the folks at Bynari Associates (any
search engine will get you there). You can see the need for marketing of
Linux and Open Source tools in their daily business. In fact, the articles
themselves are a form of marketing, gaining name recognition for Bynari
(see, it works!) in the Open Source community, while sharing the benefit of
their "real world" experiences of implementing "Linux" for paying clients. 

In short, the line between the coder and the customer relationship doesn't
look quite so distinct from here.

Later,
Jerry S.

Message-ID: <3.0.1.32.20000308102356.0068b264@bizux.net>

I am new to Zope but I am very appreciative of the How-To's and Guides that
have been produced by those that are more experienced than I in the use of
Zope. 

I am currently working on intranet for the company I work for, and am
having problems creating an instance of a ZClass, that I created, (DCTask,
which is actually the product, DCTaskClass is the ZClass)through the a
public interface (form that requires the entry of information that will be
added to the instance in the form of properties, such as the description of
the task and which department it is created for).

The form that is used to submit a creation action resides in a created
folder (http://diis/tasks/generator) and therefore does not reside in the
folder where the DCTaskClass_add method resides. I think that my main
problem, though I could be wrong, is that I haven't found a way to access
the _add method from the /task/generator folder through the use of the
<FORM ACTION="...">. I believe that once I have can access that file
through the form action and have the ability to send all of the relivant
information I will be able to create instances through the use of the
public interface (ie. the form)

Any help will most appreciated.

Best regards,

If you have a programmer and a web designer around it's possible to 
seperate the two tasks quite well, though, in my experience. Likewise a
situation with a programmer and a content manager, which is the situation
I'm in right now.

Still, both the web designer and the content manager want to know more
about Zope, and this does throw them off into the deep end (Python,
DTML, object oriented programming, etc).

I won't chop it off; you're right. Though I would say a simpler DTML
is only half of the story; the other half of the story is already there --
people _can_ use drop-in components. It's just that we need more and
better drop-in components (with possibly a nicer interface, ala Zope PTK
and/or Zope Mozilla).

Still, a simple variety of DTML would be nice. Currently you can
successfully use a subset of DTML, which almost has no arcaneness but
is still very powerful. PythonMethods will help even more there. Still,
DTML allows too much, so it's too easy to move into the arcane domain. Also
some of its powerful features have the side effect that some of the simple
features look too complex.

So perhaps we should create a seperate language, based on the subset,
with simplified syntax, which _doesn't_ allow fancy stuff. The fancy
stuff would be in DTML-methods or PythonMethods of some kind. Perhaps 
even the HTML would be in seperate methods. Perhaps some XML-ish Zope
glue language, like this:

<zopeglue>
<var object="header"/>

<assign name="age" object="get_age"/>
<var object="show_age_intro" arguments="age"/>

<var object="layout.table_header"/>
<in object="get_above_age" arguments="age">
<var object="myrecord" arguments="in_item"/>
</in>
<var object="layout.table_footer"/>

<assign name="age" object="getage">
<var object="footer"/>
</zopeglue>

And then some IDE that allows you to easily create all objects you
refer to here. Perhaps something wiki-like; any object name that you refer
to in the glue that can't be found will be presented in a list after you
edit the glue, and you can create objects for it then.

Ideas, ideas, now for some time. :)

Martijn

I would recommend taking a look at how the management interface does things.
(Just do a View Source in the Zope management frame that has the pull down
menu listing the different things you can add).

In KM|Net News, I made the incoming article form post to a DTML method
(AddArticle) that basically follows the steps in the "Adding ZClass
Instances Programmatically" how to.

http://www.zope.org/Members/tazzzzz/addZClasses

I haven't tested this, but posting your form to:

"manage_addProduct/YourProductName/YourZClass_add"

may do the trick, assuming your form is being called from the Folder where
you want the new instance created. Otherwise, you should do something like:

"/FolderForNewInstance/manage_addProduct/YourProductName/YourZClass_add"

The new scheduled DTMLMethod product, ZScheduler, can do that. Just schedule
the method for "now". Only works with DTMLMethod's but they can call any
other kind of method. The product is in alpha stages right now, so I
wouldn't use it for a production environment just yet, but I would
appreciate knowing whether it's useful for your application.

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time. 
The Z2.log file shows
123.123.123.123 [08/Mar/2000:16:49:40-0700]

The actual system time is  8:49 pacific time.
NT 4.0 show   (GMT-0800 UTC)  Pacific time (US and Canada);Tijuana
It and is set to automatically adjust for daylight saving time.  

I have a NT 4.0 windoze  workstation machine that is running Zope latest version 2.1.4. and of course python 1.5.2.
  
Is there a script file that needs adjusting to make the file log correctly?  I know that -700 is UTC is Mountain Standard Time.  Do Zope programmers like the warm southern climate better than the cold  climates?  In short can this "default" be changed.

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

Subject: [Zope] Setting title in an external method
Message-ID: <20000308121007.A561@cnri.reston.va.us>

Hi all --

A common idiom around here is to use an external method to process a
form and, if an error that the user can't fix occurs -- eg. you can't
view such-and-such an object because it doesn't exist, or you don't have
privileges -- use "return" to show them the contents of a DTML method
that explains the problem.

Here's a simple example:

    def my_xm (self, REQUEST=None, RESPONSE=None):
        # ... churn away, processing the form ...
        return self.my_dtml (self, REQUEST, RESPONSE)

Here's the source for the "my_dtml" DTML method:

    <dtml-var standard_html_header>
    title: <b><dtml-var title></b><br>
    document_title: <b><dtml-var document_title></b>
    <p>
    This is the <dtml-var document_id> Document 
    in the <dtml-var title_and_id> Folder.
    </p>
    <dtml-var standard_html_footer>

Both "my_xm" and "my_dtml" are in the root directory of an almost-fresh
Zope 2.1.4 installation.

The problem is that the "title" when I call "my_xm" (ie. the "Title:"
HTTP header and "<TITLE>" HTML tag) is just "Zope", which I presume is
the title *of the folder* containing the external method.  Yuck.  I want
the form result to have a title of its own, eg. "Error Viewing
Blah-blah".

What's the best way to do this?  Possibilities that occur to me:

  * redirect to the error-reporting DTML Method instead (but I like
    to keep the number of redirects to a minimum)
  * use a DTML Document instead of a Method (not sure if this will
    work, and sometimes I really do want it to be a method -- eg.
    it might be called from within a larger Document in some context)
  * set some magical attribute of 'self' or 'RESPONSE' in the external
    method; I tried "RESPONSE.setHeader ('Title', 'My Title')", but
    that didn't work

Any other ideas?  Thanks --

        Greg

This is bizarre:

I added this line to the form ACTION... after I took a look at how the
management interface was adding the DCTask.

manage_addProduct/DCTask%20/DCTaskClass_add

(what the heck does the DCTask%20 do?) Before it couldn't find the product
DCTask (attribute error) and now it finds the product but I get a key error.

Error Type: KeyError
Error Value: id

This is the code that I have for adding the adding ID of the instance of
the class (it provides a random ID or at least generates on)

<dtml-call "REQUEST.set('id',_.random.random()*10000)">
<dtml-call "REQUEST.set('id',_.str(_.int(id)))">

Try htmllib.

The following bit of python will strip all formatting from some HTML. It 
replaces all anchors with footnote style references and images with 
their alt text. If you want something a bit fancier you could add 
methods to the MyParser class to pass through particular tags (see 
the commented out methods as an example). It shouldn't be too hard 
to wrap something like this up in an external method (as presented it 
is a complete runnable program that retrieves a URL and displays 
the text).

--------- File strip.py --------------
# Strip all HTML formatting.
import sys,formatter,StringIO,htmllib,string
from urllib import urlretrieve,urlcleanup

class MyParser(htmllib.HTMLParser):
    def __init__(self):
        self.bodytext = StringIO.StringIO()
        writer = formatter.DumbWriter(self.bodytext)
        htmllib.HTMLParser.__init__(self,
            formatter.AbstractFormatter(writer))

    def gettext(self):
        return self.bodytext.getvalue()

# Uncomment these to pass through bold tags.
#    def start_b(self, attrs):
#       self.formatter.add_flowing_data('<b>')
#
#    def end_b(self):
#        self.formatter.add_flowing_data('</b>')

def GetPage(url):
    try:
        fn, h = urlretrieve(url)
        text = open(fn, "r").read()
    finally:
        urlcleanup()
    return text

if __name__=='__main__':
    data = GetPage(sys.argv[1])
    p = MyParser()
    p.feed(data)
    p.close()
    text = string.replace(p.gettext(), '\xa0', ' ')
    print text
    anchors = p.anchorlist
    for i in range(len(anchors)):
        print "[%d]: %s" % (i+1, anchors[i])
--------- end of strip.py --------------

Subject: [Zope] Object Manager and Folder
Message-ID: <E12SkGf-00074X-00@home.delysid.org>

Hi.

I am quite new to Zope and currently try to create a BookClass ZClass Product.
I came across several issues where you probably can give me some useful tips:

1. What is the difference between inheriting rom Object Manager and/or Folder.

2. My product will include Cover Images of the books. (a small and a large one).
Whats the best way to implement this? I thought about creating emtpy images (smallcover and largecover),
but I dont know how to ask the Objects if they contain something.
Or should I just add the Images in my BookClass Instance programmatically?

3. Wasn't their any web-client product for Zope so that I could retrieve content from the web directory and import it in Objects (like a Image) without having
to upload it manually?

And the last one:
Is their any special reason why FTP access doesnt work in the /Control_Panel/Products folder?
All methods are empty their. I work with Emacs and ange-ftp is quite
a good method to access content of Zope Objects.

Besides, if I change the content of a Object through the web interface,
Zope seems to convert < > and " chars into &lt; &gt; &quot;
I understand why, but is this really necessary. It seems as if nearly all
textmode browsers (as lynx and emacs/w3) dont care about converting the entities back tto their corresponding characters.

Thanks in advance,
               Mario <mlang@delysid.org>

If you can figure out improvements on how to configure UW IMAP for
interoperation with WorldPilot that would be great. We're currently
lacking 
a UW IMAP server with a reasonable amount of data on it for looking into
the
issues.
I'm putting in a parameter to control the LIST call, I think that should 
reduce the load for the large part of the users, but we're open for any
further
adaptions.

Ryan

I am hoping to add some performance benchmarks, quotes, etc... In other

Message-ID: <OFA5CFA31F.A45A80B0-ON8525689C.006234C6@ssga.ssb.com>

I just installed Zope (on NT) and would like to have reasonable
backup/recovery options.  One way to do this is to just make a copy of the
data.fs file in the var directory, but I'm concerned that this file may not
be in a consistent state when it gets copied somewhere.  Should I worry
about this?

I'm thinking it would be better to eliminate this file in favor of an
Oracle or Sybase database (I have access to both).  Can I do this?  If it
is possible, would I want to do it?  If I should want to do it, how do I do
it?  I've spent a few hours searching the documentation, but this has only
convinced me that it may be possible -- I've been unable to find a
definitive answer.

Ok that seems to work because I am getting other errors and I think this
task is a little advance for a zope infant like myself. Now, this line is
causing me problems (this happened after I called entered the hidden field):

<dtml-call "REQUEST.set('id',_.str(_.int(id)))">

The error it gave me was:

Error Type: ValueError
Error Value: invalid literal for int(): generator

It seems to be refering to the "(.int(id)))" of the above code.

Dave & Chris,
Thanks for replying.
I'm running Caldera OpenLinux 2.3.  I chose it because I heard that it had
one of the smoothest installations.  I am only a few months into Linux; I'm
transitioning over from the Dark Side (Microsoft).  Heehee.

Here's my best guess at what's going wrong with the MySQLDA/db installation.
I think it is related to access rights or locations to the
libmysqlclient.so.6 file.  When I run build.py, I can see the script
accessing the MySQL library folder (in my case: /usr/local/lib/mysql)  This
is the path the MySQL 'make install' script displayed when it was done
installing MySQL.  I checked, and the library files are there.  Anyway, I
can see the build.py script working some of its magic within this folder, so
I feel confident that the paths in the Setup.in file are correct.  However,
it is crashing when it tries to "from _mysql inport *".  I am not (yet) a
Python programmer, so I don't understand the implications of this import.
I'll reprint the error message I received for anyone else that reads this:
Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I like your idea of making a link to the MySQL library file
(libmysqlclient.so.6).  I know this is a stupid question, but if I run:
ln  /usr/local/include/mysql libmysqlclient.so.6
what will the link be called, and where will it be located?  How will this
help the build.py script?

Thanks again for your input!


Chris,
This seems to be pretty common which makes me feel, well, not alone...

Thanks for the note and I'll keep you updated on my progress.

I reinstalled linux (probably didn't need to but I did)  I used an older

and see if it can now find the libraries/files it needs.

Are you sure that the Setup.in path is correct?  I looked at both these
files build.py and MySQLdb.py they both refer to libraries and their

I probably going to change over to mandrake linux for security reasons.

I've never used Caldera's distribution, but if it's anything like Red Hat,
the following should work:

1) Open /etc/ld.so.conf with your favorite text editor and append the
directory in which libmysqlclient is located.
2) Run 'ldconfig'

This will update the list of directories that the linker searches.

Let me know how it goes.

I am impressed with the products I've seen so far but they can always be 
improved and there's certainly room for more. Perhaps there should be a 
coordinated 'wish list' on zope.org so that developers can pick up on 
needed products, or collaborate  on enhancements of existing products ?

Well that's a bit further than I was proposing. Perhaps I would settle for 
dtml which accessed the REQUEST object more simply. However your syntax 
looks good.

What "non-standard" syscalls? I'm talking about calls like lseek().

Yes, spawn a new thread.

WARNING this can cause havoc if not done properly.  For example, if you
want your seperate thread to be able to read and write data to the
database, you MUST open a seperate connection to the DB.  If your thread
goes away, you MUST close that connection.  There are a couple how-tos
on the site that explain database connections.

Yes, that makes sense. When it looks up "id" in the namespace, it first
comes across the id of your method. You're specifically wanting the "id"
from the REQUEST variable. So, the line should be:

<dtml-call "REQUEST.set('id',_.str(_.int(REQUEST['id'])))">

Nope. The Data.fs file is simply appended to when things change, and it is
quite safe to just copy the file over.

It *can* be done, but you would need to write your own ZODB Storage
mechanism for it. Right now, there are a few Storages available. FileStorage
is the most common (the one that works with Data.fs). There is also
CompressedStorage and BerkeleyStorage. No one has written a storage for an
RDBMS yet, but it should be possible.

Would you want to do it? Probably not. The FileSystem storage is pretty
solid. About the only thing you'll get from the RDBMS storage is that you
wouldn't have a file that keeps growing with every transaction and needs to
be packed from time to time.

Hi Chris (Carlson),
Thanks for the reply!

1.  I added the following line to my /etc/ld.so.conf file:
    /usr/local/lib/mysql
2.  I ran 'ldconfig'
3.  I re-ran build.py.  Here is the new error message. (notice that the last
line changed from before):
Traceback (innermost last):
   File "build.py", line 14, in ?
     import MySQLdb
   File "MySQLdb.py", line 19, in ?
     from _mysql inport *
 ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

Note that the file '_mysqlmodule.so' is in the
'/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' directory

4.  I tried adding '/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' to my
/etc/ld.so.conf file, re-running ldconfig, then re-running build.py, but I
got the same error.

It seems like we are getting a little closer!  Any more guidance would sure
be appreciated!

Thanks again,

Eric.

Subject: [Zope] Zope authentication problem
Message-ID: <v04220807b4ec46d1b515@[192.168.0.16]>

I apologize in advance for this note. I know this topic has come up 
several times in the archives, and I swear I've read every post, 
every how-to, and every other bit of documentation I can find. I 
can't get past the management screen authentication for Zope with 
Apache.

Here's my environment:

OS:		RedHat Linux 6.1

Zope: 		version 2.1.4, installed from Jeff Rush's RPMs (thanks, Jeff)

Zope PCGI:	version 2.1.4, also from Jeff Rush's RPMs (thanks again, Jeff)

Apache:		version 1.3.9, installed from the Red Hat RPMs (both base
		and devel RPMs are installed)

Python:		version 1.5.2, from the Red Hat RPMs


I'm configured as follows:

Zope install directory:		/var/zope

Zope.cgi:			copied to /home/httpd/cgi-bin/Zope
				(not a symlink, and renamed 'Zope')

access file:			/var/zope/access, contains:
				admin:cleartextpassword

httpd.conf contains:

RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/static/(.*)   /home/httpd/html/$1 [l]
RewriteRule ^/Zope(.*) /home/httpd/cgi-bin/Zope$1 
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

(that last line is all one long line, and I'm pretty sure I've sorted 
out the ls and the 1s properly)



Zope is launched with the following command:

cd $INSTANCE_HOME  (/var/zope)
/usr/bin/env python z2.py               \
         -z      /usr/share/zope         \
         -u      zope                    \
         -Z      /var/run/zwatchdog.pid  \
         -p      /home/httpd/cgi-bin/Zope \
         -w      ''                      \
         -f      8021                    \
         -m      ''                      \
         -l      /var/log/zope           \
         2>&1 >> /var/log/zope           \
         &

I can access all my other (non-Zope) CGI programs normally. I can 
access my static html with URLs of the form:

	http://server.ucop.edu/static/some_silly_url.html

So, I'm pretty sure that both CGI and the rewrite modules are 
installed, configured, and working properly. I can run Zope and see 
the QuickStart materials, so I'm pretty sure that the basic Zope 
installation is correct. But I can't get authenticated to Zope. 
There's nothing in the logs for httpd or Zope that looks interesting 
to me:

httpd - access_log:

207.212.67.31 - - [08/Mar/2000:10:14:18 -0800] "GET 
/cgi-bin/Zope/manage HTTP/1.0" 401 1388

Zope log (syslog messages file):

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- - 
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782

/var/log/zope is empty.


I've tried about a zillion other things, including installing the 
Zope binaries instead of the RPMs, and installing and building the 
Zope source. In every case I end up with the same result. Zope 
doesn't accept the authentication. One oddity I noticed is that if I 
access Zope through:

	http://server.ucop.edu/Zope

it immediately requests authentication. It doesn't even show me the 
opening screen or allow me to browse the QuickStart. If I dodge 
around the RewriteRule by going directly to:

	http://server.ucop.edu/cgi-bin/Zope

then it doesn't ask for authentication until I try to hit the 
management screen.

I should probably add that I tried using the built-in Zserver Python 
package and it worked fine. I haven't tried Zap. I would prefer to 
use Apache because I want to serve a mixture of legacy HTML and Zope 
content. I would prefer to use my own Apache instead of Zap because 
in general I'm not comfortable with using a package that I can't 
maintain at the current release level. Zap Apache trails plain Apache 
releases, at least by a little bit. I've tried a whole raft of 
variations on the rewrite rules in Apache. I'm stuck.

Anybody out there been through this already?

We need a couple more data points before we can blame Zope for this or

Try just REQUEST.set('title', 'Foo')

Folder inherits from all kinds of other things, including
ObjectManager.  Basicly, if you want your object to be a container then
subclass ObjectManager.  If you want to look and walk and quack exactly
like a Folder, use Folder.

They have a getSize() method that returns the length of the Image (Files
have this too).

Sure.

Yes, any automatable HTTP client will do.  You might want to look into
ZClient, or xmlrpclib, or httplib.

Yes it is, I'd like to see this too.  I don't think it would be too
complex for someone to do, certainly FTP support is fairly trivial.  For
this you would need to mine the source.

I don't understand.  Editing a DTML Method through the web should not
munge it in this way.

Create an new kind of Storage module that stuffs database records into
table rows, instead of a file.  We've hypothisized on this, and it is
very possible (the 'fs' in Data.fs means 'FileStorage', which is the
kind of storage used by default on Zope.  Other storages include
DemoStorage, BerkeleyStorage etc.  There is no saying you couldn't have
a RelationalStorage).  Butdo you REALLY want this?  Consider:

1) Relational databases do not store previous revisions of record
information.  You will have no Undo capability.  I guess with some
extremely fancy SQL or if you engineered the Storage to do some kind of
mapping, you could emulate the storage of previous revisions.

2) One of the benefits of RDBMS is that they can be used by outside
applications.  The data Zope stores however will be record objects,
basicly python pickles, information which is useless to other apps.

However, it's really not a bad idea, except for the no Undo part.

Yer gonna kick yourself if this is it, but I believe that you must have
a RewriteCond before each rule that you want the conditon to apply to,
so in this case your authorization information is poked into the
environment for your static content, but not Zope.

Duplicate the second line after the third and see if it works.

Message-ID: <3.0.1.32.20000308144541.0068c798@bizux.net>

I have a group of ZClass (DCTasks) stored in a folder
'/tasks/generator/taskstorage'

The index_html of '/tasks' is the interface to view the instances and
certains properties that are saved on those instances. One of the
properties is 'task_title' and is displayed as a hyperlink to view the rest
of the properties of the instance.

This is my problem, when I check the source of the page (/tasks/index_html)
and I take a look at the hyperlinks for viewing the properties of the
instance, it gives a URL like so:

http://diis/tasks/generator/taskstorage/<string>

<string> should actually be replaced with the 'id' of the instance. This is
so by the DTML code for index_html:

<a href="<dtml-var URL1>/generator/taskstorage/<dtml-var id>">
  <dtml-var task_title>            
</a>

I have no idea why a string is taking the place of <dtml-var id> in
referance to the instance.

Any ideas would be helpful.

Best regards,

Well, basically what you are doing here is moving the point of
potential corruption from zope to the relational database.  This may
or may not give you any comfort.  For me, it makes me more nervous
since I don't have the source code to those particular databases, and
thus couldn't fix things if the worst does happen.

World domination has nothing to do with it. If Zope were the only tool
out there (or if it were enjoying the same kind of monopoly iron grip on
the market), that'd not be a Good Thing.

At the moment, Zope is still very much a "guerilla" product. It follows
that you might have to use guerilla tactics to lure it into your
company. Like Linux was just 1-2 years ago.

Arguably, free software (or Free Software) is about freedom, not
necessarily about what's right or what works.

RMS, arguably the grand old man, top banana, and icon of the Free
Software movement -- which is not the same as Open Source -- openly
admits he'd rather have bad, free software than good, non-free software.
The Open Source movement takes the pragmatic view that bad, free
software isn't an improvement at all, and that the software industry has
little use for RMS' moralisms. The Open Source guys just wants "software
that doesn't suck".

Perhaps Free Software people don't care about marketing. But then making
good impressions or having good hygiene has never been top priorities
for geeks. ;-)  For some people, outward perceptions do count. I flinch
every time somebody sets up Microsoft Exchange Server, or buys some
pricey piece of non-compliant Internet software, or seriously argue the
significance of ASP.

The people who make such decisions are often, sadly, uneducated about
what's good and about "software that doesn't suck". *Other* people
suffer because of such misfires.

Here's a different perspective you might not have taken into account in
your salutations to the spirit of Free Software. If Linux *hadn't* been
picked up by huge corporations and stock markets, if Linux *hadn't* been
rampantly commercialized, would we have seen the surge of wonderful
developments and innovations for the OS that we're seeing now? Methinks
not.

As much as I abhor commercialism and the new Linux hype, Linux' implicit
"world domination" plan is doing good things for the OS. Linux is not
the ultimate OS and hopefully won't be the last stop on the way to
utopia, but I rather look forward to the point where it's usable as a
desktop OS and I can forever throw out the software I know for a fact
sucks.

Marketing, in the case of Open Source/Free Software, is mostly a tool to
educate ignorant brass. *We*, as you point out, don't need the stuff.

Subject: [Zope] Puzzling DTML method results
Message-ID: <4.2.2.20000308154134.00b99280@saladin.aisys.com>

I'm encoutering a puzzling result with some DTMLMethods that I've 
written.  I have some code which is used to display a list of information 
derived from a catalog.  The information presented varies, based on which 
"category" of information the user desires.  The DTMLMethod which generates 
most of this information looks like this:

<dtml-in "InternetLinkCatalog(meta_type='Internet Link Info', 
categories=_['categoryName'])" sort=name>
    <dtml-with "InternetLinkCatalog.getobject(data_record_id_)">
        < ... display object stuff here ... >
    </dtml-with>
</dtml-in>

For testing purposes, I created another DTMLMethod in the same folder named 
'categoryName' and initially all it contained was one line:

Accounting

When I displayed the contents of my folder (which utilizes the list 
generation method),  I received a list of all objects which belonged to the 
category of Accounting.  I'm now trying to extend my code to use an actual 
category name specified by a user (or from a url clicked on by the 
user).  I changed my 'categoryName' code to look like this:

<dtml-with REQUEST only>
<dtml-if category>
    <dtml-var category>
<dtml-else>
Accounting
</dtml-if>
</dtml-with>

If I view this method, the result is 'Accounting', which is just what I 
would expect.  However, when I attempt to view my generated list in the 
same manner as before, I get no results.  I'm confused.  When the 
categoryName simply has the value 'Accounting' in it, I see results.  If I 
change the method to include some processing (but still answer the same 
thing), I get no results.  I'm sure that I'm just doing something stupid a, 
but it's getting late in the day and I'm not seeing what the problem might 
be.  Can someone help explain why I'm getting two different results for 
what should be the same?

Thanks.

I bet your ZClass inherits from either DTML Method or DTML Document, and
then the following article applies:

Is this comparison available?

Or going to be available?

kb

>>> From: Patrick Phalen <zope@teleo.net>:

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

I can't see the problem either, but I suggest changing your method to
this:

<dtml-if category>
  <dtml-return category>
<dtml-else>
  <dtml-return "'Accounting'">
</dtml-if>

The <dtml-with> is unecessary.  Note the single quotes inside the double
quotes.

This might fix it, might not, not sure.  But here you are explicitly
returning a string, not a formatted document.

Subject: [Zope] creator/owner attribute of an object? Mime-type of a file object?
Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AC@VRTMAIL>

I'm attempting to create a directory list (well, the final version will be
more complex, but this is where I'm stuck).  I'm looking for some way to get
the creator ID for all of the (file) objects in a folder.  I'm also
interested in getting the mimetype, but this is less critical.  Here's what
I have so far:

<dtml-in "PARENTS[0].objectValues( ['File'])">
url <dtml-var URL1>/<dtml-var id>
title <dtml-var title>
id <dtml-var id>
size <dtml-var size>
ddate <dtml-var bobobase_modification_time fmt="%m/%d/%Y">
owner 
mimetype <dtml-call "getContentType()">
</dtml-in>
<dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')">

Unfortunately, getContentType always seems to return null strings, and I
cannot find any attribute which shows the owner/creator attribute of the
object. If the creator is not available, the last editor would be fine.

Pointers appreciated,
Mike

Message-ID: <F32B7D6249C5D31187DB00C00D00F78C076EF8@weebo-2.osip.com>

Hello,

I've been trying to decipher the Zope member log in screens.  It appears
pretty straight forward.  There is the login.html screen which is basically
just a form for entering Name and Password and then passing this information
to logged_in.html.  I'll ignore the cookie for now.

logged_in.html then checks <!--#if "AUTHENTICATED_USER.getUserName() !=
'Anonymous User'"--> and reports success or failure.

However, as usual, there's got to be something I'm missing.  If I simply
build those two pages, the AUTHENTICATED_USER.getUserName()  check on the
logged_in.html page always return 'Anonymous User'.

When and how do I get the form to actually 'chat' with Zope and make me a
valid authenticated user?

Thanks in advance for any help provided.

	-mark

PS.

For those who are still having a problem with DCOracle and Oracle8i, that's
working great for me now.  If I can help, feel free to send me email.  I'm
running all this on RH Linux 6.1

I've been watching this debate since the begining and felt I'd put in one
observation on the above quotation. I actually think one of the comments in
this vain (maybe by ESR) was the goal for "software that sucks less" than
the whats out there. I don't think you can create software that doesn't suck
in some person opinion.

That said what I've learned is if I have to have software that isn't quite
where I want it to be I prefer the ability to adapt it myself. One argument
against open-source software projects is that they often come from amorphous
groups on the Internet. (Zope is an exception.) As a result there is no one
to "hang if it fails". What people don't factor into the equation is if I
have to pay $X for licenses from a vendor (with or without a support
contract) how many hours of contractor time will that buy me to install,
customize, administor, and maintain a freely available open-source product?

For those fighting this battle inside corporations I recommend
http://www.cluetrain.com as a place to visit.

That did the trick.  I hadn't thought about putting primes around a value

Hello Zopistas -

FSSession 0.3.0 is available at:
http://www.zope.org/Members/gaaros/FSSession

FSSession 0.3.0 corrects a few reported bugs and has now working support
for Zope Transactions (thanks to Hung Jung Lu for valuable discussions).
Users of FSSession should upgrade to the newer version. Feedback
especially regarding speed will be appreciated.

People are indeed working on Python, but not to the extent of more
popular projects like Linux or even, I believe, Perl.

Compiler/language projects have, historically, not thrived in the
collaborative world of open source software -- for very specific reasons
inherent in the concept itself of languages and compilers. Still, I'm
very impressed with the evolution of next-gen GCC (formerly EGCS).

I consider Skaller's Vyper project a fringe project with limited
applicability, because Ocaml itself is a fringe project -- it's
certainly not what you might call a mainstream, popular language.
There's something icky about an OcamlPython. However, I'd love for it to
succeed. (Unfortunately, Skaller is already out on a limb, implementing
all sorts of stuff he deems interesting -- so true CPython compliance
isn't necessarily on his agenda, and fragmenting Python like this is,
imho, not a good thing.)

Anyway, while I have not been monitoring the Python type/interface SIG,
it seems to be moving quite slowly.

I'm not saying they're holding back, but rather they're dismissing speed
and scalability as being a problem. I firmly believe that speed is
Python's number of problem today, and it's keeping Python from being
used in more applications.

Python has plenty of problems, but they're tiny by comparison and imho
they're mostly artifacts of Python's currently somewhat anemic syntax
(eg., only two kinds of loops, no "switch", no protected members, no
constants, no syntax for declaring mutability).

Imho Python's second big problem is what you might call, in lack of a
better term (I'm not wearing my compiler-writer hat right now, sorry),
contractual semantics -- anything from static typing (pass a string to a
function that takes an int and you get either a compilation error or an
exception) to interfaces (the ability to enforce semantic compatibility)
to design-by-contract constructs.

I disagree, but there's only one way to find out -- implement it (or
simulate it very carefully).

Not potentially. Definitely. I thought about this yesterday, and I got
to thinking that it would probably be pretty simple to create a dynamic
native-code generator that translated bits of bytecode on-the-fly, with
the necessary stubs implemented in a small helper-assembler written in
C. Something like:

  def Halibut():
    ...

  import codegen
  c = codegen.Translate(Halibut)
  c()  # Call native-code function Halibut

and then with whole modules:

  import pickle, codegen
  pickle = codegen.Translate(pickle)

Internally, Translate() would disassemble the bytecode, generating
native assembly language code and pass it to the helper C module, which
would store it in an executable buffer and fix up the necessary
references to the Py* API symbols.

Just a thought.

It would be an interim solution for certain CPU-intensive modules, in
anticipation of such built-in functionality in CPython itself. Possibly.

Well, I guess they're too busy arguing about whether Python should allow
assignments as expressions so you could do "while line = f.readline():".

Thanks,
The problem is fixed. The box with the ftp server had PARANOID host 
deny settings. This caused user's with incorrect reverse IP lookup
nameserver settings to be disconnected.
Sorry :-( 
You should all be able to download now (but maybe get in touch with
your domain administrator/ISP and get your DNS entries corrected, if
you previously had trouble ;-)

Cheers,

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * A Documentation Survey has been posted.  This survey will help
    Digital Creations decide where to focus our efforts by allowing
    you to tell us what you think about Zope documentation.

    http://www.zope.org/Members/Amos/Documentation/DocSurvey

  * "efm" has made a set of RPM distributions of Zope 2.1.4.

    ftp://www.tummy.com/pub/tummy/RPMS/

  * Maik Röder has posted an announcement regarding the Zope
    Documentation Project (ZDP).  Among other things, the ZDP has a
    new site.  It's a fantastic resource, and definitely worth
    checking out.

    http://www.zope.org/Members/roeder/zdp

  
New Products

  * Software Product: NFG Navigation Product, submitted by "gyst"

    Another product which provides navigation widgets such as trees
    and maps.

    http://www.zope.org/Members/gyst/NFGnav

  * Software Product: ZopeEDIT, submitted by "jimbag"

    This product allows you to edit DTML object from your Zope
    database in your favorite text editor.  Maybe.  Written in Python,
    so it just might work on your machine.  This is _not_ a Zope
    add-on, it runs on it's own.

    http://www.zope.org/Members/jimbag/ZopeEDIT


Updates

  * Software Product: mod_pcgi2, submitted by "phd"

    The update to 1.0.2 adds new documentation.  This is module allows
    Apache to communicate with long-running PCGI servers, such as Zope.

    http://www.zope.org/Members/phd/mod_pcgi2

  * Software Product: load_site.py with additional features, submitted
    by "Itamar"

    This is an enhancement to the load_site.py utility that comes with
    Zope.  It can be used to fill a Zope database with content from a
    filesystem.  This release, version 1.2, fixes all known bugs, has
    new features from the newest version of the original load_site.py,
    and runs in 'standalone' mode, loading into a remote Zope server.

    http://www.zope.org/Members/itamar/load_site/load_site1.2

  * Software Product: FSSession, submitted by "gaaros"

    FSSession allows you to store persistent, per-visitor information
    on your filesystem.  This update, to 0.3.0, fixes a number of bugs
    and properly supports Zope transactions.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: KM|Net News, submitted by Kevin Dangoor

    KM|New News is a weblog (news site) product, not unlike (but not
    identical to) Squishdot.  This update is version 1.1.

Zope.org items

  * How-To: Managing http/https URL Links, submitted by "rbickers"

    This How-To describes a clever method to generate links to objects
    which require different protocols (http or https).  This allows
    you to use encryption only where needed, without using exclusively
    absolute links.

    http://www.zope.org/Members/rbickers/http_https_ulinks

  * How-To: How to view all inherited and acquired attributes and
    methods of an object, submitted by "dmost"

    This How-To is essentially an educational (or debugging) tool.
    Often it's difficult to figure out what methods an object has, or
    where those methods are coming from.  This How-To provides an
    external method which lays it all out for you.

    http://www.zope.org/Members/dmost/ViewSelf

  * How-To: User Defined Roles and Proxies, submitted by "lvogel"

    "This HOWTO is to give a brief explanation of what a user defined
    role is, why you would want to set one up, and how to go about
    creating one. I also briefly touch setting up a proxy on Zope
    objects."

    http://www.zope.org/Members/lvogel/proxy

  * How-To: Change TinyTable values using DTML, submitted by "cguardia"

    "The TinyTable product is a good tool if you need simple table
    lookup functionality in your Zope apps. However, it's usefulness
    is limited by the fact that it doesn't support writing single
    values to the tables you create."

Hi Matt, Hi Jack,

What were your IMAP/SMTP settings prior to setting them to localhost?
Were they empty or pointing to a specific host name?

Cheers,
Ryan

In my case, they were, for IMAP, my local machine name, and for SMTP, my
ISP's (Roadrunner's) SMTP server.
IMAP has always worked great.  SMTP has been the problem.  I have not tried
Jack's solution, as I can't use localhost
for SMTP.

Thanks for any help,
Matt

I am getting a strange error when I try to access the Properties tab of
one of my objects called "News":

ErrorType: InError
ErrorValue: Strings are not allowed as input to the in tag.

The traceback is as follows:

Traceback (innermost last):

InError: (see above)

What does an error in the input to an "in" tag have to do with accessing
the properties tab?

I could be wrong, but I suspect that this has something to do with an
assignment I made to a lines property that belongs to the "News" object.

Something to the effect of a string being assigned to a lines property?
(I make this assumption because I have had this error come up before
with lines properties. In this previous case, I just flushed out the
contents of the lines property in question using
"manage_changeProperties". This fixed the error, although even then I
never understood what the error in input to an "in" tag had to do with
the lines property value being erroneous.) As I no longer need this
property, I would gladly eliminate it. However, Zope won't even let me
in to the Properties tab. It just displays the "InError" when I attempt
to go to Properties of the News object. I can't really remember the
exact wording of the lines property id so I can't delete it via
"manage_delProperties" or flush out the contents of the property using
"manage_changeProperties".


Any insights as to what is going on and how to resolve this situation?

Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AD@VRTMAIL>

I know, bad form responding to one's-own post, but I did figure it out and
thought other newbies might find it useful...  The first (trivial) problem
was that I had a typo (dtml-call instead of dtml-var) which prevented the
content-type from displaying.

"type" "<dtml-var "getContentType()">"

The creator/owner attribute can be got at by going through the
get_local_roles method then searching for a value that has "Owner" in it,
and copying the corresponding key.  I'm sure my dtml is atrocious, but hey,
I just learned it this afternoon :) .

"owner" "<dtml-in expr="get_local_roles()"><dtml-let
temp=sequence-item><dtml-if expr="temp and 'Owner' in temp"><dtml-var
sequence-key></dtml-if></dtml-let></dtml-in>"

Enjoy all,
Mike

Having a slow machine, not having to restart the server when testing is
important for me (it is a 20 second start up for me).
Is there a script around to let me do this... ?

Here is what I have done so far (using bits of snippet from the source):

log into the monitor, and do this:

import Zope
app = Zope.app
c=app()
OFS.Application.initialize(c)
c._p_jar.close()
del c

The net result is all items in the the "Add New Item" combobox double up,
and I am not even sure if this does the trick...

Good idea. Zope needs some more languages anyway.
Apache for example has mod_negotiation for this.

please not: the q argument is not meaningless.

I think a better way would be to implement a true negotiation mechanism.
That is, if the request comes, zope has to look for languages available
and rates them according to the language preferences coming from the UA.
Then it sends out the highest rated document, that might be the first
of the items in accept-language.
So each document (could be a folder?) schould have an attribute to
identify
its language capabilities. 

A simple branch would imply you have all documents in all requrired
languages.
I in doupt you can make this happen.

Easy with a second string.split(_.['sequence-item'],";")[0]

Message-ID: <14534.58177.603725.668441@antares.int.plain.co.nz>

As the tiny little text box on the survey page isn't up to long
dissertations, I'll post my comments here:

The guides need better examples and blank spots filled in, in
general. The DTML guide, in particular, needs a canonical explanation 
of the quoting rules and shortcuts so new DTML hackers understand why
you can get away with this:

<dtml-let foo=bar> ... </dtml-let>

But still need to do this:

<dtml-let foo="'constant'"> ... </dtml-let>

There is still a lot of docs using the old, ugly HTML comment style
tags, too, which is confusing, and there are a lot of examples of
using '_' and REQUEST to kludge up a temporary namespace when
<dtml-let> is the accepted means to kludge up a namespace[1].

The HOWTOs and Tips are potentially the basis of an excellent Zope
cookbook, but they require more stewardship from DC:

- They need more structure. Catagorizations like
'Authenication/Authorization', 'Using RDBMSs' and 'DTML tricks' would
save a lot of search time and provide hints towards missing
documentation. 

- The need to be vetted. There are a lot of docs with incorrect
examples and obsolete information that need to be tidied up. 

John

[1] Who the hell came up with a scoped assignment tag?! Why not
implement a <dtml-set> tag that isn't a container and that assigned to
a temporary namespace that persists for the duration of a DTML objects 
rendering. It can have a special attribute that you use to commit
changes made to an object in the temporary space back to it's
persistent name space, and you'd have a decent assignment tag.

It is the name of a method that will be called when the File is accessed.
You can use it for checking a session cookie, or anything you need from the
REQUEST.

If you then want to deny access to the resource, because your precondition
hasn't been met, the method can raise an exception.

I dont know if this is possible, but one feature of any tree-transformation
language that might be usefull to me would be the lazy construction of
nodes, or the creation of a virtual tree that is in fact a live view of the
source tree. XSL seems to be designed as a batch-processing language, which
seems at variance to the principles behind zope.

No, sorry.  Python has a 'reload()' built-in, maybe that could be

Message-ID: <4.2.2.20000308192207.00e638e0@127.0.0.1>

I'm new with Zope.

One thing I'm looking for how to do is the effect that one document might 
virtually be stored in multiple folders.

For example, if I keep a hierarchy of folders that is an archive of 
articles, maybe stored chronologically in a folder for each month or 
something like that. But then I also want those same articles to appear in 
other folder hierarchies, categorizing and organizing them in various ways. 
And I don't just want to put duplicates of the document in there. I'd like 
that if somebody updates the original, the virtual documents in the other 
folders update too.

Is there some obvious DHTML statement or trick I don't know about yet? Or a 
Product that does something useful about this? Essentially I'm looking for 
an equivalent to symbolic or hard links to files in a Unix file system.

Subject: [Zope] what defines the absolute_url() prefix?
Message-ID: <38C72738.F8CB3EB8@picknowl.com.au>

G'day,

I'm having a blast using (technically: playing with :-) Zope 2.1.4 on
a RedHat 6.1 box, and mod_pcgi2 (1.0.1).  For my first efforts, I've
built a set of DTML methods which emulates www.python.org's style of
website, with an index_html method that "includes" Banner, Sidebar,
Body etc methods, which can be over-ridden in lower-down folders. 
All funky stuff, works well.

In the Sidebar, I have links to folders within the site using
absolute_url() (because of issues with BASE HREF giving me multiple
folder syndrome).  I can access the folder with the URL
http://localhost/cws/Help (and the logfile shows "GET /cws/Help"), but
the absolute_url() method on cws.Help is actually returning
"http://localhost/cws/cws/Help" (which is also accessible - kinda odd,
but not what I want).

I kinda suspect I've screwed the mod_pcgi2 config, mainly because its
the area I'm the most confused about :-)  I have the following config
in Apache:

<Location /zope>
    SetHandler pcgi-handler
    PCGI_ROOT /
    PCGI_SetEnv SiteRootPATH /
</Location>

<Location /cws>
    SetHandler pcgi-handler
    PCGI_ROOT /cws
    PCGI_SetEnv SiteRootPATH /cws
</Location>

(Oh, and I've just added a <dtml-var REQUEST> to the Help page, and
it's returning URL http://localhost/cws/cws/Help/index_html for
accesses to http://localhost/cws/Help, so it's awfully consistent
in its behaviour.

How does zope determine what the prefix is, and better yet, how do I
fix it to mesh with reality?


Regards,
  Daryl Tester

Flemming,

What you have described is exactly what Acquisition does.  Say you put a
document 'DocumentFoo' in your root level folder.  You could access that
document a number of ways:

/DocumentFoo

/AFolder/DocumentFoo

/AFolder/AnotherFolder/DocumentFoo

this happens for you automatically right now.  Try it youself, create
some folders, put a document somewhere 'above' them (like in the root
folder) and it will work.

Message-ID: <003b01bf8988$d50e3960$0402a8c0@toil>

Exactly how do you get zope to work under apache with fastcgi?

I found 2 documents on the zope site dealing with this issue and they both have
command options "-pass-header Authorization" like
FastCgiExternalServer /home/httpd/html/z -host localhost:8999 -pass-header
Authorization

This produces an error as an invalid option, and looking at the documentation for
the FastCgiExternalServer directive it is not an option. The version of fastcgi
is 2.2.2 which is the same version they say to use in the documentation.

Does anyone besides Digital Creations know how to make this work? I have tried
this a bazillion ways from apache rpm's and binaries, but can't get it to work.
Someone must know how to do it.

Thanks

If you look around at Zope.org, you'll see that most content physically
resides in Member folders. But the same content can also be found through
the Documentation, Products and Reosurces pages.

We use the ZCatalog for this. You can build up pages with searches, thus
allowing multiple views into your content.

We are currently developing a thing called 'Topics', they exploit this
feature in an automated way. You specify a search on them, and they will
thus model a view into your indexed content. This way you can generate pages
with your articles by month, or by topic.

I think he typoed 0.2.3 instead of 0.1.2. 0.1.3 is out as of today (or
yesterday), but shouldn't offer any improvement in conjunction with Zope,
so you don't need to rush out and get it.

The main hurdle that people installing MySQLDA with MySQLdb seem to have
is, they want to try to compile the stuff in the src directory that
ZMySQLDA provides. This is MySQLmodule, which is the old interface. Just
rm -r src. There is a patch that comes with MySQLdb that needs to be
applied to ZMySQLDA. Once you've done these two things and installed
MySQLdb on your PYTHONPATH, you just need to restart Zope, and make a
ZMySQLDA Connection object (or whatever it's called).

I don't think a new syntax should be brought about. There are too many things
to learn already, it will only add to the confusion.

I do agree that dtml is complex and something needs to be done about it.
Probably a subset of the current dtml itself - with minimal additions which
make somethings easy - would be good.

Also (if this is seriously being considered) I would favour for a somewhat
different paradigm:

Instead of:
> <var object="layout.table_header"/>
> <in object="get_above_age" arguments="age">
> <var object="myrecord" arguments="in_item"/>
> </in>
> <var object="layout.table_footer"/>

We could have:
<dtml-var object="layout.table">
<param name="datasource" value="get_above_age">
<param name="columns" value="Name,Age">
</dtml-var>

The advantage here is that:
   o   One logical presentation element (a table) is one element in dtml code.

   o   One-to-one relation is possible between the code and any GUI entity
        being used to design (think ZStudio). This means the layout.table can
        be one icon that is dropped into a design view and it's parameters
        specifed through some fancy widget. 
        Also when the code is stored and reloaded, it would still be
        possible to display the same GUI entity in the design view and it's
        parameters would be editable.

Discussions on the above have taken place on the ptk and zope-moz lists.

That is a very peculiar error. Py_InitModule3 is a symbol from Python
itself, so if that's missing, I don't know what's wrong. Well, I can guess
a little, and my guess is, while you have Python installed, you don't have
the development libraries. With RedHat, this is python-devel, but may be
something else with Caldera. Actually, Py_InitModule3 is a macro in
Python.h, so if it's looking for that, then Python.h is probably not being
found, which could mean that the -I flag in Setup (or Setup.in) is not
right for your environment. But you would have all kinds of build errors,
I would think.

Try this:

find /usr/include -name Python.h -print

If nothing comes up, then the development stuff isn't installed, or it's
installed somewhere else.

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Subject: [Zope] Zope Question : Virtual folders / URL's
Message-ID: <009301bf89a9$afced7b0$0201a8c0@iridium>

Have been reading the docs but still not clear on a few things.

I have my site mapped out in my mind. It has URL's like :

mysite.com/          (main page)
mysite.com/rss     (rss content for mysite)
mysite.com/<username>  (main <username> page)
mysite.com/<username>/rss (rss news content feed for <username> page)

Where I come from data belongs in a database. I'm happy for all my HTML to
be in the ZopeDB but not any application data (users definitions, news items
etc etc).

So, looking at my URLs I see that there are a mixture of static and virtual
folders.

mysite.com/index_html is obviously static though it contains dynamic
content. Doing this with Zope is easy and obvious.

mysite.com/Fred/ is a dynamic page. Fred only exists as a username in a
users table and related information in other tables. It's not obvious to me
how I go about serving this page because I can't create a static page for
every username (nor do I want to).

Clearly mysite.com/Fred/rss will use almost identical processing to the
mysite.com/rss page, just different parameters so re-using my "rss"
generating code is important to me too.

I'm know these virtual folders can be served up by Zope. Can someone tell me
what I am missing?

Last I heard about this, the status was "Not available".
http://lists.zope.org/pipermail/zope-ptk/2000-February/000323.html

But soon (hopefully!), I'll be releasing iTrack - an Issue Tracker Zope
Product. I haven't really used the ptk tracker so I can't give a comparison.

Well, it's a "feature" I can live with (otherwise it wouldn't be working
at all :-).

Tried that too, no joy (with all possible combinations of PCGI_ROOT and
PCGI_SetEnv, as I don't exactly understand its affect on Zope itself).

The dump from the REQUEST Session state shows (for both settings of
PCGI_SetEnv, plus some judicious editing):

URL:		http://localhost/cws/cws/Help/index_html
URL0:		http://localhost/cws/cws/Help/index_html
SERVER_URL:	http://localhost
REQUEST_URI:	/cws/Help
PATH_INFO:	/cws/Help

SiteRootPATH: changes (from /cws to /), so that's something.  :-)
From an environmental point of view, things appear OK (but what
would I know, I've only be using Zope for just over a week).  I'm
not sure how absolute_url() is constructing the full URL, but I guess
it would be from those above components (there doesn't appear to be
anything that defines the absolute hierarchy that I can find).

On a whim, I tried http://localhost/cws/manage, and the urls on that
page suffer the same problem too (eg, in the left hand frame there are
links of the form "http://localhost/cws/cws/Help/manage_workspace").
At least it's not just my DTML methods. :-)

Subject: [Zope] Indexing dtml/html files
Message-ID: <v04205508b4ed3dfc6467@[130.227.115.35]>

Hi,

Is it possible to use catalog to index ordinary html pages intelligent ?

If I have a html(dtml) file like:

<HTML>
<p id=title>
Are you Intelligent ?
</p>
<p id=author>
A. Einstein
</p>
</HTML>

I would like to index the title and the author id's, for which I could search.

Is it possible ??

   Well, let's me clarify a bit. PCGI_ROOT is the folder (or other object)
in Zope which will serve your requests. In your situation it is folder
"cws" in root folder.

   PCGI_SetEnv is *only an example* of how to set per-request environment
variable. Whatever variable you'll use and what value to set - it is up to
your configuration. In my example it is variable SiteRootPATH.

   This variable only works with SiteAccess. I use SiteAccess pretty
happily, and it solves all my virtual hosting needs, including rewriting of
BASE, absolute_url, etc.

   Without SiteAccess you'll get exactly what you get - additional path
components.

expand_all and collapse_all are all very well but I think Andy is after the same
thing that I gave up on. 

How can you expand or collapse a tree to a specific point, ie:

- make a particular subtree expanded 

- make sure a particular node in the tree in visible

The Zope DTML guide mentions the tree-s, tree-e and tree-c variables but it
doesn't explain how to use them. I haven't found any help anywhere on this.

Any ideas?

That's true, but that shouldn't hold us back indefinitely; some things are
can only be improved after a while if they're redesigned from scratch, 
otherwise the back-compatibility issues become too complicated. I don't know
if DTML is at this state though, and any new language proposal should be 
something to consider for the (very) long term.

But you lose some flexibility in defining table headers and footers;
you have to be careful your simple language becomes too rigid, making
too many assumptions.

Hm, what you're proposing is some higher level object (a product) that
does tables (in this case). That would in fact be rather neat.. Our simple
glue language could become extremely simple if we have sufficient higher
level components, and if it's easy enough to code up your own components.

I'm doing something like that for web forms in my ZFormulator product.

Okay, this kind of discussion probably belongs on another list, I agree. :)

I guess you could do it in XML-documents, that are
inherently more machine-readable than html..
Otherwise, storing title and author in properties would
do the trick for zcatalog..Not exactly what you ask for, but
as close as i can get with my skills..
I guess you could write a pythonmethod to extract title
and author from the html and store them in properties so
that they could be easily indexed..

Usin tree-s/c/e is going to be a bit problematic.

In my understanding those vars are built from the context of the node in the
tree, so if you add/remove anything to/from the tree then the tree-s/c/e
will change.

There doesn't seem to be anyway of going to a particular point in a tree
with any certainty.

I did this on one site for example, it's a prospectus for a college, the
tree is built from calls to a sql database.  Adding or removing records from
this database totally changed the tree-s/c/e vars that each node is
associated with.

I hope I'm wrong about that but I have a horrible feeling that I'm right.

Please someone prove me wrong.

actually I do have xml documents also but it is for an automatic 
system where the upload is done via webdav or ftp. So I need a way to 
upload Zope xmldocuments from a client.

I am not a Python programmer and would rather find a solution without 
doing some coding. But I have found the urls to find and update the 
index from the client. But now I need to upload xml documents to Zope 
AS xml documents. Is there an easy way to this ?

I don't know enough about Perl to judge this, but to me, there's
plenty of activity out there. Of course there could always be more,
but lots is happening.. We have _three_ independent implementations of
Python, for instance (Python, JPython and Vyper, and then there are
projects like Python2C).

Sure, it's not easy to do. I would debate that compiler/languages have
not thrived in the open source world, though. There seem to be
quite a few successful open source languages around.

[assessment of Vyper with which I agree]

That's the nature of discussion lists, almost. There are some prototype
implementations of type-checking systems for Python, though (I think
two or three independent ones, in fact).

Hm, but in my experience Python has been shown to be plenty fast enough
for the majority of applications. You're probably right though, and I
agree completely that a faster Python would be very nice.

I suggest you go discuss these things on comp.lang.python. :)

I don't miss switch. Functions are first class objects, and dictionaries
can be used instead of switch when necessary. Also, good object oriented
design tends to kill switch statements anyway.

I think the two loops are fine, though it would be nice to have the
current constructs to know about iterators. I believe Guido is
taking that into consideration. Also there's the list-comprehension
proposal which may help here. 

I don't think you'll see protected members any time soon.

I'm not sure what you mean with syntax for declaring mutability, though
it sounds interesting.

The types-sig is reaching consensus about optional static typing and
Guido does want to include that into the language in the future (beginnings
in 1.7, full implementation in Python 3000 aka Python 2). Interfaces are
being considered too, and Jim Fulton in fact has an interfaces proposal
out there (that may get used in Zope's code base).

I think using a unit testing framework can substitute for design by

Okay.

[snip code generator extension idea]

Something like that would definitely be neat. The hard part would be
in the translation process, of course. The other part is in the
interfacing with regular Python; do you allow your translated function
to refer to other Python objects? If you do, you're opening a can of
worms. If you don't, then it starts to look like the 'Swallow' subset
of Python I proposed once; a strict subset of Python with added full type
annotations, which is translatable into C or native machine code.

If you're starting such a project I want to hear more about it!

Not to mention indentation! Anyway, the people who keep bringing these

PCWeek did a shoot-out of various CMS packages about six months ago. 
They created a "scoresheet" that might be useful.  Unfortunately,
Vignette stood by their policy of not allowing their software to
reviewed, so it includes several other CMS packages.

Message-ID: <4.2.0.58.20000309114320.01881df0@192.168.0.2>

Hello Darran,


building on Rik's previous answer, how about this:

   <dtml-call "REQUEST.set('myObjRef', _[desired_id])">

It tested OK with an Image object called "image" and located in the site root:

# Storing the image name in a variable
<dtml-call "REQUEST.set('desired_id','image')">

# Creating an object reference based on the variable
<dtml-call "REQUEST.set('myObjRef', _[desired_id])">

# Displaying the object title and size
<dtml-var "myObjRef.title">
<dtml-var "myObjRef.getSize()">

# Rendering the object if it's renderable. An image is.
<dtml-var myObjRef>

If it's not renderable, you'll end up with something like "<Folder instance 
at 01368880>" in the HTML page source code.

Does it work for you? If yes, you may want to add a FAQ Question and it's 
Answer on zdp.zope.org (hint, hint :-).


Cheers.

The answer in my case is both.
My test box is called "geezer" so initially it was set to "geezer". This
designation works with other IMAP tools (ishmail, Netscape). When this didn't
work I tried the FQDN: geezer.lab.jacku.com (My exposed FQDN is different due
to masking by the cable modem company.) This provided a similar error. Reading
the doc files I decided to leave the fields blank. This also generated an
error. (I don't remember at this point if it was the same exact error.) After
that failed I entered local host for both options and it worked. This became
the "last test" since its result was positive.

Hope this helps.

Hi Folks,

I sometimes et the strange and quite inconvenient problem that the
treeview of the manage interface gets spacing of a few cm's between the
(+) sign and the folders on any folder below the 2nd level. The result is
that the tree is quite wide. Does anybody else have this problem?

It seems to be happening if more than one or two branches are expanded,
but I haven't pinned the exact problem down yet. I use 2.1.4,
debian-packaged zope. Is this a known bug, can I help in some way in
tracking it down?

If there is a 'multiple select' on the property sheet with no value
initialized, you can get this error.  This seems to be a long-running
bug with multiple selects.  At the moment, it is important that the list
(or lines property) has values before creating the multiple select, and
then you must establish a value for any new multiple-select by selecting
one or more of the items in the multiple select as soon as you create
it.  I think the bug is in the collector, but I cannot be sure.

HI,

In the python interpreter I have done the following things:
>>>import sys, ZODB, ZODB.FileStorage
>>>db = ZODB.DB(ZODB.FileStorage('/usr/local/zope/zope214/Data.fs'))
>>>root=db.open().root()

Where 'Data.fs' is my Zope DB with a lot of stuff. Then I did the following
things:
>>>root.__dict__
>>>{}			#result of the previous "command"
>>>dir(root)
>>>[]			#result of the previous "command"
>>>vars(root)
>>>{'container' : {}}	#result of the previous "command"

I expected to find the stuff I have in my Zope DB. I double checked to look if
I didn't made a typo on the longname of my Data.fs file, but all seems ok. I
also saw that the modification time of Data.fs.lock and Data.fs.tmp were set to
the time I run db=ZODB.DB(....... so I guess I chose the right Data.fs file.

Can someone tell me where am I wrong?

Thanks

Hi,

When I have a form with a <textarea> field set to submit to an sql
method, ['it gets stored','like this']. How do I get around this? Do I
have to do some special formatting before submitting to the SQL method,
or is there something I must do in the SQL method declaration itself?
I'm using <dtml-sqlvar fieldname type=string> because this was the best
I could find in the documentation. Is there a type=lines? If there is,
someone please put it in the ZQR.

Another: I want a text holding ZClass for storing text pages. Deriving
from DTML Document or Method seems the obvious choice but I have an
issue with that: the content must be rendered thus:

<dtml-var standard_html_header>
<dtml-var raw newline_to_br>
<dtml-var standard_html_footer>

I suppose I have to override rendering for my ZClass and insert this
code. How do I do this?

Message-ID: <3.0.6.32.20000309100628.0079b6f0@spicklemire.com>

This concept was kicked off by a specific need that led to discussions 
of polling, XML-RPC, Java RMI, JavaScript, and others that I can't recall. 
But, an unrelated need brought it home last night. The ZSchool project 
will at some point involve lot's of folks who won't be online constantly*, 
and suddenly Client Side Zope starts to look interesting. 

Keep in mind, it's Zope! For those of you who have sworn off all things 
Microsoft and have grown accustomed to the "joys" of compiling and 
tweaking Zope / Apache / etc. on all varieties of *n*x, you may not 
realize that getting Zope running on Windows takes about five minutes. 
Thats five minutes for a newbie. It's just a Windows "Install".

Now, if anyone mentioned Client Side Oracle Application Server, or Client 
Side Lotus Notes, we'd know they'd lost it. But Zope is actually small and 
nonintrusive enough to pull this off. Think about a world full of Zopelets, 
on all those nifty palm thingies. Your local WorldPilot could sync up with

Hmmm....

Very interesting, I agree that installing Zope on Win* was very easy. The
problem I have is how to Sync stuff between my local Zope at home (no net
connection) and the 'real' Zope at work.

I currently do an export to a ZIP disk, and then an import back into the other
Zope from the disk. This makes a lot of things possible but only in very limited
circumstances:

You have to move *all* of Zope, or objects don't re-import back into the correct
place. Also, if an object changes on the 'real' Zope changes while I'm at home
and I import when I get back, the changes are lost as my import overwrites
whatever is there...not pretty.

Also, I can't do this trick with things like Squishdot postings, which is a
shame...

What would be nice is something like Lotus Notes replication when you import a
.zexp file; you get a replication conflict if both objects have changed, which
you can then sort out.

I'm not looking for the full-blown ZEO distributed object store, just a way to
periodically sync a set of selected objects (slightly more complex in the
squishdot case...) by exporting from one and re-importing (non-destructively)
into another.

Any ideas?

Hi,

  Is there any way in Zope to validate information
(news, new document) by third party before real
publishing.

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  How can I do this kind of things with Zope? Is it
possible?

  Any suggestion? links? help?

Message-ID: <4.2.2.20000309104029.00be1b50@saladin.aisys.com>

I know that there have been several threads on this list concerning the way 
to pass arguments to a DTMLMethod.  I've done what I think is correct, yet 
my result is less than pleasing.

Here's what I have and what I'm doing.  Hopefully someone will identify 
what I'm doing wrong.

In my web sites root folder (aka /Foo), I have a DTMLMethod named 
"siteRoot".  It simply answers "Foo".

In a subfolder of Foo, I have a method named "linkFor".  The code for this 
method looks like this:

/<dtml-var siteRoot>/SomePage?option=<dtml-var optionValue>

In the same folder that contains the "linkFor" method, I have another 
method which wants to use the result of the "linkFor" method.  In this 
method there is a line which looks like this:

<a href="<dtml-var "linkFor(_, _.None, optionValue='some value')">">Some 
Text</a>

When this code gets executed, I get a "KeyError" on "siteRoot".  For some 
reason, when my linkFor method executes, it can't see the siteRoot method, 
even though the method exists in the parent folder.  What am I doing 
wrong?  Why can't linkFor see siteRoot?

Thanks.

I have never seen the Python interpreter crash in any way, nor have I heard
of it doing so. I havent seen this, but my partner tells me he as seen the
Perl interpreter crash. I have seen the Java JVM crash many many times. Some
of my Python code has been running 24/7 for the last 18 months.

I would say that, as languages or interpreters, Python and Perl are equally
and extremely stable. As tools for developing software, Python's object
oriented foundation is conducive to the building of more stable _systems_
that Perl. This could be because of the language itself, or because of the
programmers it attracts.

Most of the Perl programmers I have met are, frankly, obscuritan mess-heads.
The concept of structured programming is somewhat anathema to the Perl
programmer. I looked over the shoulder of one Perl programmer we had hired,
who was having trouble with a database import problem for several weeks.
This Perl programmer had written 6 pages of perl code without actually using
_any_ indentation. The program was full of nested loops and she was having a
difficult time debugging her code. Without knowing any Perl, I cleaned up
the indentation, fixed a few glaring problems, and handed it back to her.
She had the problem solved at the end of the day.

It comes down to this: It is hard to write a program in Python that another
Python programmer (or the same programer several months later) wont
understand. It is easy to write a program in Perl that another Perl
programmer wont understand.

As for the outside consultant. Ask them what makes them feel that Python is
less stable than Perl, and what exactly that means.

   There are mnay ways you can do it. Publish it in some hidden location
and later move it into public area. Use Versions. Develop your own
mechanism for publishing...

  Is there any way in Zope to validate information
(news, new document) by third party before real
publishing.

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  Any suggestion? links? help?


[RH] There are several ways to accomplish this:
You could put the document in an 'incoming' folder and make a reviewer move
it to the publishing location (this also allows for letting the reviewer add
keywords/categories etc).

If the uploaded document goes directly to the documentation where it is
published, you could give it a property called 'approved'; reviewer invokes
dtml method which sets the approved property to 1. The document is not shown
unless the ' approved' == 1.
[untested simplistic dtml]

<dtml-unless "approved==0">
   <dtml-var <document>>
</dtml-unless>

I believe the Squishdot product
(http://www.zope.org/Members/butchland/Squishdot) allows for something like
this.

A third (more sophisticated) possibility is to combine the two approaches by
using the Catalog, more or less like the Zope site does:
contributions by members are submitted for approval to the Zope site
administrators, who then add them to the site's catalog. Then they are
available in pages that use the catalog for their contents (like the howto
pages, the products pages etc). In your case reviewers could also add
keywords/categories etc to the document before it is cataloged and the
catalog may index these. I do not think the Zope site approach is available
for the public, but it shouldn't be too difficult to implement it.

A related product is ZDP tools (http://www.zope.org/Members/roeder), which
does not exactly do this but may be a source of inspiration for workflow
management. Another workflow system in Zope is Xen (I do not have the URL
handy right now), but this may be overkill for your needs.

Hey James,

Just in my experience I have never had a problem with the stability of
either Python or Zope. I have set them both up on multiple servers (RH 6.0,
6.1) and been pounding away at them for months now. Python 1.5.2 has been
out of awhile (a year?) and Zope releases are certainly stable. In fact,
having been using Python for web CGI scripting for 4 years now I have never
had a problem with the stability of it as a language (run it on NT, Mac,
Linux and Solaris boxes). I usually just build it and let it leave it, never
needing to look back till I am ready to update it.

2 folders are next to each other, one is called test1 the other test2. They
are within the same Home folder, but one is not within the other. Can an
index_html document in test1 grab a dtml-var from test2? How is this done?
In html i would simply write ../test2/dtml-var. This does not work in Zope.

Message-ID: <v04220803b4ed7c0e4906@[192.168.0.16]>

I can confirm and reproduce this problem, and on a totally different 
architecture - Red Hat Linux system with Zope 2.1.4. Here's a snippet 
from my /var/log/messages file:

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- -
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782


Notice that the timestamp from the syslog facility is the correct 
local time, March 8 10:14:18, which is Pacific Standard Time. On the 
very same line, the timestamp passed to the syslog from Z2 is in GMT, 
08/Mar/2000:18:14:18 -0700. My guess is that Zope isn't picking up 
the $TZ environment variable. What I don't get is why it's showing 
GMT as 18:14:18 -0700. That would imply a local time of 11:14:18. I 
think it should be 18:14:18 -0800 right now, and -0700 during 
daylight savings time. Two, two, two bugs in one!

I think you are safe in classifying this statement as FUD.  I've been
using Python (outside of Zope) for five years.  I even had a non-trivial
accounting system that my business depended on running in Python.
A bad design decision on my part led to some real problems with memory
size and CPU use of the resulting program, but Python never crashed
no matter how much data I tried to shoehorn into my badly designed
system.  Python is rock solid.

So does KM|Netnews (available on the products page on zope.org).
If it doesn't meet your publishing needs, you might want to look
at its code to see an example of a way to do it.  (I haven't looked

I have a simple two field table in MySQL, "whowhat", that pulls a user id
from one table, and a class code from another.  (It tells you "who" has
"what" classes)

I , being somewhat new to python & Zope, am having the darndest time trying
to do a simple external method to do a count of how many times the class
"so-and-so" is in the table. (That way, I know how many people have
signed-up, and how close I am to the class max.)  I have tried different
searches.  I have an SQL Method that does:

select * from whowhat

And I also have one that does:

...
select * from whatwhat where classcode = <dtml-sqlvar class_name type=nb>

I've been trying to create an External Method, but I just can't seem to get
it to work. (yes, in the Extentions directory)

I need to try to stay away from doing a "select count(classcode)..." in an
SQL Method if I can.

Any help to this tormented soul would be greatly appreciated.

Subject: [Zope] Having slight problems with <dtml-calendar>
Message-ID: <3.0.1.32.20000309114825.00698938@bizux.net>

Problem:
  Currently I have no problem view the HTML tables of the calendar or
adding properities. Where my problem lies is displaying those properties in
the tables of the calendar.

Currently the variables for the date, whether the object has a property,
and the value of that property are registed just like the <dtml-calendar>
How-to.

<dtml-let d="date.Date()"
          hasdate="hasProperty(d)"
          dprop="getProperty(d)">

The 'd="date.Date()"' does what it is supposed to. (make d equal to
something like 2000/01/17). I checked the hasdate variable and found that
it was equal to a 0 (1 if true, 0 if false, of course).

The properties are kept on the folder, where the calendar method is. I
added a property via the method for doing such and went back and checked
the folder to see if it had a property on it. Yes it did... in this format.

Tree Structure:    /diis
                     /calendar (contains the properties)
                       index_html (displays the calendar)
                       /updatecalendar
                         index_html (used for editing the properties)
2000/01/17 This is the 17th day of January.

Yet, hasdate was equally 0 (false) therefore the 'dprop' value could not be
set.

I guess my question is this:
  If the folder containing the calendar method has properties on it which
are   to be read into the tables of the calendar, does this mean that
'hasProperty(d)' is not being read off the folder and is looking at some
other object for the value?  

If that is not the question can someone please point something out to me
that I am doing wrong...

All help is extremly appreciated.

Best regards, 

Mark J. Stahl

The testamonials continue...

I wrote a perl app a few years ago for a customer, about 10,000 lines.
It produces a book in postscript from a database of info. They run it
once a week. It crashed at random. After 6 months, I couldn't read my
own code, comments or not. I ended up rewriting in Python and it has run
without a hitch for about 2 years AND I can still read and understand
the code. I hesitate to write a thing in perl anymore, and if I am
forced to, won't support it. I've had Zope and numerous other programs
in Python running without one crash EVER! Believe it!

It really depends on how bad your intentions are. Could you use
subclassing? Or do you want to add methods dynamically after instance
creation?

I am not sure what you mean by dtml-var but I assume you want to access
some attribute in test2. You can make test2 attributes accessible in test1
by:

<dtml-with test2>
tarari tarara
</dtml-with>

Message-ID: <20000309110821.A2683@devware.com>

I have seen a couple of people mention zope lockups on here before and
I haven't seen any myself until just recently.  (I have zope on about
5-6 machines and this is the first time I've seen this happen)
Anyway, how can I diagnose this problem?  So far I have only seen it
happen twice, but it was twice in the last 24 hours, and I'm getting
ready to roll out this app to some users.  I'm concerned!  Anyone have
any suggestions?

Symptoms are basically that it just stops responding.  The web browser
seems to connect, but it never completes the connection.  Right now I
have it running in debug mode to see if I can catch whatever it is
with some console logging.  This is on an NT Server running NT 4.0

I believe you have to supply the (_.None, _)
parameter for the index_html method to work.

You are ALMOST ALWAYS better off using the
<dtml-with ...> tag, something like

<dtml-with test2>
  <dtml-var a_something_inside_test2>
</dtml-with>

Or in the more general case of many layers

<dtml-with "FolderA.SubFolderB.SubSubFolderC.test2">
  <dtml-var methodA>
</dtml-with>

This pushes test2 onto the namespace stack. So
your methodA can still access objects inside
the SubSubFolderC.

------------------------------------------------

Use the dotted notation, e.g:

<dtml-var "F1.SF2.methodA(_.None, _)">

only if you don't need any objects from the
subfolder F1.SF2 during the call. Most of the
times, this is not what you want.

In this case subclassing won't work and I'm not needing to do this

Subject: [Zope] Finding crash information
Message-ID: <m37lfcawfm.fsf@wacko.pdx.net>

I'm having a serious problem with my Zope server running in
production.

Platform: RedHat Linux 6 (2.2.12-20 kernel)
          Python 1.5.2
          Zope 2.1.4
          starting with: python z2.py
                         as root/nobody on port 80 straight ZServer


Under load (not too heavy, but busy) the Zope process SILENTLY stops.
I get no traceback info anywhere that I can see.  Nothing to
stdout/stderr, nothing in Z2.log.

If I start as: python z2.py -Z '' to prevent the fork and detach I
still get no message when the crash occurs.  

I can't run this in DEBUG mode because I'm using GUF cookie mode to
authenticate and the login screen ends up showing an exception error
(by design?)

If anyone can tell me how to run in DEBUG mode but make GUF still hide
the exception error that would be a big help.

If anyone can help me keep this server from crashing every forty-five
minutes I'll buy 'em a beer next time they're in Portland.

BTW, the site is very non-exotic.  GenericUserFolder with a lot of
static content and one ZCatalog w/CatalogAware ZClass.

Let's say in Zope you have SQLMethod whowhat and SQLMethod whatwhat.  In
your external method you should simply be able to do:

def countWhoWhat(self):
  return len(self.whowhat())

def countWhatWhat(self, class):
  return len(self.whatwhat(class=class))

These should return the result count for each SQLMethod.

Now, I now I can do this using JavaScript on client side, by doing something

MyFunc()

form.submit();

}

So is it possible to do this without JavaScript ?

I never had any problems, but then again, I'm not sure I've ever done this with
index_html, or in quite the way you describe.

Done it lots with calls to SQL methods and other DTML methods, but I don't think
they reference other objects themselves...

Hi all,

I have built a trivial ZClass : CD (from CDProduct, from the guides).

I try to add a DTML Method "render_short".
This method would render the CD Instance on one short line.

My ZClass has simple attributes (artist : string, title : string,
description : text)

I would like to be able to write this simple "render_short" DTML method like
:


Artist : <dtml-var artist>
Title : <dtml-var title>
Descr : <dtml-var description fmt="structured-text" newline_to_br>

But when I insert a <dtml_var myCDInstance> in my index_html, I got a
exception :

Error Type: KeyError
Error Value: artist

There is no typo in my code...
How can I access to my ZClass instance attribute from inside its methods ?


Please help me :)

Olivier

Is this a pure Python question? (Zope External methods
are VERY different from Python methods, that's why I need
to ask.)

If you are talking about pure Python, sure, you can add
class members (data or method) at any time.

-----------------------------
File A.py:

class Chicken:
    def __init__(self, size):
        self.size = size
--------------------------------
File B.py:

import A

def getSize(self):
    return self.size

A.Chicken.getSize = getSize

b = A.Chicken(123)
print b.getSize() # prints 123
--------------------------------

If you are using Zope, you must store your
classes where they can be accessed by
Python. Usually /lib/python/Shared/Local
is a good place, make sure to add the
__init__.py file inside the folder. You
then refer to the class as Shared.Local.Chicken.

What a coincidence.
 I have exactly the same problem. One site with GUF and a CatalogAware
ZClass which silently stops after some time. No errors.

The problem with GUF and DEBUG mode relates to lost filedescriptors.
Someone posted an explanation (maybe a patch too). You might be able to
locate it by doing a search on the list.

Please let me know if you find something out.

I agree. The guides need to be complete, error free, and chock full of
examples.

Hmm. I wasn't aware of the old style syntax, that should definitely be
updated. I also agree that we need to review guides and update examples
to use the latest and simplest techniques. This is especially true for
DTML.

I agree. We do have categories for How-Tos but they are not currently
sorted on Zope.org by category. Probably the categories could be
improved, too.

Again I agree. How-Tos should also provide some feedback system to allow
readers to comment on How-To and point out problems.

Thanks for your excellent ideas!

I'm a little pzzled about :

"objects don't re-import back into the correct place"

I haven't had any trouble exporting / Importing enitre branches. Of course,
I delete the branch to be overwritten first, or at least move, or rename
it. Is that how you're doing this?

XML export may come into play here, since the XML version is parsable. I'm
not aware of any existing Zope tool for dunning a comparison process.

One point that I think is still evolving is a clear set of guidelines
regarding what data is held in Zope, and what should be in other formats,
such as Gadfly. As long as we diligently keep DTML doing templating, and
avoid mixing tabular data and static content in with ZODB objects, it
should be fairly straightforward to do Zope Exports of the Zope Framework,
and file copies, or native exports of data in other "backends".

Mailman has no "global" username/password directory -- every email
address in every list has a password associated with it, that's all.
Known design flaw, and Barry Warsaw (the Mailman maintainer) has
threatened to fix it.

I think this *might* fix the problem you guys are having.  Although we
aren't using GUF or CatalogAware objects, we discovered this on a system
that was under pretty heavy load.

Hello,

I search for a way to implement an URL-Traverse like the SQL-Product. I
need some key/value-pairs for a method and won't use an URL-get like
.../my_method?key=value. Instead a .../my_method/key/value or
.../my_method/key/value/view would fine.

Has someone a small code-snipet or something like that which explains the
__bobo_traverse__ - mechanism ?

Thanks,

Hello WorldPilot Users,

There's a new WorldPilot 1.0.3 maintenance release available,
that addresses some of the interoperability issues.
Check out
http://www.worldpilot.org
or
ftp://demo.worldpilot.com/pub/worldpilot/worldpilot-release-1.0.3.tar 


Calendar Problems:
For everybody who had Timezone troubles with the WorldPilot
Calendar, this release should hopefully work for you now.

Please send us your positive or negative feedback to
mailto:feedback@worldpilot.org
so that we know if it now works around the globe :-)


UW IMAP users:
And for all the (UW-) IMAP users there is now a IMAPHACK.py 
file located in the WorldPilot Product directory. Here you
can set the Base IMAP directory (e.g. Mail or INBOX) and
you can choose to only list subscribed folders (but you'll currently
need to subscribe them with a seperate client).

Thanks for all the tips and suggestions! I hope WorldPilot will 
soon operate with most of the remaining other IMAP servers, too.
We're still working on some of those other tracebacks that got
sent in.

Cheers,
Ryan

That's OK. Please do the experiment yourself, it
only takes 3 minutes or less to verify it. You
don't need to trust my words. Trust the result
you see with your own eyes. :)

A good many people in the list have said this
repeatedly: try it first, before posting. I think
it's a little bit too much to ask everyone to
do that every time, but this is a responsible
mailing list and not some flame-loaded newsgroup.
So, when it takes only a few minutes to confirm
something simple, why not try it first?

regards,

Hung Jung

Message-ID: <20000309142919.D183689@isc.upenn.edu>

hi: I'm trying to use the BasicAuth example in the "XML-RPC How To"

http://www.zope.org/Members/Amos/XML-RPC


I keep getting the Zope error when creaing the External Method:

Zope has encountered an error while publishing this resource. 

            Error Type: SyntaxError
            Error Value: invalid syntax

--------

I've just cut and pasted this from the webpage, only removed extra padding spaces, and spliced the one big
line back together:
 h.putheader("AUTHORIZATION", "Basic %s" % string.replace(encodestring("%s:%s" % (self.username,
self.password)),"\012", ""))



The code defines a class and a def:


---------------
class BasicAuthTransport(xmlrpclib.Transport):
    def __init__(self, username=xxxx, password=xxxx):
        self.username=username
        self.password=password

    def request(self, host, handler, request_body):
        # issue XML-RPC request

----------------
In the Add External method page, where you enter in the Function name I've tried:

request
BasicAuthTransport
BasicAuthTransport.request
request.BasicAuthTransport

Which is the right one? it want's the Function 'request', right?

So, the syntax error must be something in the script.

Any help would be appreciated.

You *can* actually get Python to crash if you're intentionally mean to
it.  All the ways I know of involve tricking it into blowing the C
stack, like:

	class C:
	    pass

	C.__init__ = C; C()

Not that you could expect that construct to do anything useful anyway;
you wouldn't ever see code like that in an application.

You have to go out of your way doing really bizarre stuff get it to crash.
It's very stable otherwise.  :-)

Message-ID: <38C8037B.8AD7F12C@digicool.com>

First of all, what you want can be done, but it is not that easy.  There
are a couple problems with your design goal, some Zope's, some yours. 
Luckily, the alternative is *very* easy ('very' being a relative term
here, basicly it means you don't have to re-engineer Zope).

You probably know this, but when Zope is tooling down through objects is
traverses them according to various rules.  First, it does something
special (we'll get to that), then it tries to find the next object in
line by just seeing if the next object is a subobject of the current
(getattr).  If that fails it tries to get the next objects as a sub-item
of the current (getitem).  If that fails, then it gives you a 404
telling you it couldn't find the next element in the URL you provided
(you being the client).

The special thing it does is it calls __bobo_traverse__.  This is a
special method.  So you override the root level folder's
__bobo_traverse__ to see if your 'virtual folder' is a user and then
proceed from there.  This is the problem: 1) You can't override the root
level folder, because it's not a folder, really, it's the entire Zope
application and 2) we override it allready so we beat you to it.

Further, although simple, I think you will come to hate having all of
your users in your root folder namespace.  Generally, you want to keep
this namespace as unclutered as possible for many reasons.  One good
reason is that everything in the root folder is acquireable by
everything else, so it's 'prime real estate' in Zope.  Another is what
if one of your users wants to be named index_html?  Or rss?  Your
__bobo_traverse__ method will either have to know all the special names
you want priority on and do the users second, or whatever.  Complex. 
Prone to error.

What you really want is this:

mysite.com/Users/Fred/rss

So you need a special object, in this case instanciated with the id
'Users', that takes the next argument in line as a key into a database,
and doesn't break acquisition paths along the way and lets you do this
fancy URL manipulation.  This special object can have a much simpler
__bobo_traverse__ method, because it's not also trying to deal with
other objects in the same namespace, the 'Users' namespace is dedicated
solely to serving these virtual path elements.  This special object
should also be very generic, not database specific, and should be
programmable directly with various SQL code to execute the query you
want.

This special object allready exists and does everthing you want to do,
it's called a ZSQL Method.  ZSQL Methods can accept arguments in the
URL, and maintain acquisition so you can apply results to 'higher'
objects.  In fact, you can even chain ZSQL methods together to do
multiple database look ups.  Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.

Nifty eh?

Exactly, absolute_url tools up through the various aq_inner wrappers to

Hi Andy,

In my MySQLdb directory, the Setup.in file contains the following:

_mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt

Note that this does NOT point to the location of the Python.h file, as you
suggested it should (below)

I've just finished recompiling and installing Python, Python-devel, MySQL,
MySQL-devel; after each step, I tried to run the build.py script and each
time I get the following error:

 Traceback (innermost last):
    File "build.py", line 14, in ?
      import MySQLdb
    File "MySQLdb.py", line 19, in ?
      from _mysql inport *
  ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

I even tried installing just MySQLDA and that failed, too.

<EXTREME FRUSTRATION>All I want is to be able to connect to a MySQL DB from
Zope.</EXTREME FRUSTRATION>

Any assistance is greatly appreciated!

Eric.

<guess>

You must still use medusa (ZServer, in this case) even if you want to
use PCGI (which is what Zap uses).  ZServer listens to many protocols,
like HTTP, FTP, and PCGI.  If you don't use medusa, PCGI will try to
fire up Zope the OLD way, and it will probably work but it's not the
right way.  The problem is, now your process environment has the wrong
LD_LIBRARY_PATH (and a whole slew of other problems related to running
Zope the old way, like no concurrency) and cannot find your Oracle
dynamic libraries.

Run ZServer first.  Then Zap.  Then it should work.

Yes, the Catalog can be used programatically from DTML and Python.  You
will have to implement your own parser (look at the standard htmllib in
python) that feeds the parsed attributes into the Catalog.

Does it do it out of the box?  No.

I'm sure this is simpler than I'm making it out to be, but here goes...

I'm looking at using SquishDot as a 'home page' for our Intranet, but can't
seem to make its index_html show up as the default document.  What I'd like
is for a user to be able to point his or her browser at
"http://www.mysite.com" and get SquishDot, outisde of setting up a redirect.
What's the easiest way to do this?

I looked at this once and my mind got lost in a sea of table tags.  If
you pin it down conclusivly as a bug, we'll fix it.  But it never
happens on Exploder, and I haven't seen it on Mozilla yet, so I'm

Yeah, and blue people are dumber than green people and orange people are

The perfect counter argument is.  "Prove it."  If this person asks *you*
to prove it, show them the Lawrence Livermore National Labs, the
mems-exchange (all multi-million $+ scientific establishments), Jon
Udell articles, etc etc.  There is a mountain of evidence on your side

Subject: [Zope] newbie closing in on Zope / IIS
Message-ID: <NDBBKGBPJMFODAAFNMKEOEANCAAA.mduvall_22030@yahoo.com>

I think my Zope is working with IIS, but some of the icons in the Management
screen can't be found.

For example, the Control Panel icon is fine:
http://localhost/scripts/zope.pcgi/p_/ControlPanel_icon is indeed there.
This looks like an object reference, right?

The Folder Icon:
http://localhost/scripts/zope.pcgi/misc_/OFSP/Folder_icon.gif , however, is
not. The same is true for the User Folder and DTML Method gifs (and a few
others). In the Zope install, the gifs are in the
root\lib\python\Products\OFSP\images folder.

I'd welcome any suggestions. It's a minor problem, but it's a bit of an
eyesore. Thank you!

Regards,
Mitch Duvall
mduvall@webversant.com

P.S. There was a thread about Zope / IIS last month. I was in a similar
situation in which all I could see when I got to step 6 in Brian Hooper's
how-to was the "Welcome to Zope" page. The change that got me into the
Management screen and logged on was to use the default 401.5 error message
for IIS' "Default Web Site". My thanks to all who've helped out.

Not without javascript, clicking on a lick causes a GET.  Clicking on a
form button causes a POST.  I could be wrong, but I'm pretty certain
that's the convention.

Subject: [Zope] ZClass, Base Classes and logic (QUEST)
Message-ID: <00030915401200.06239@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

Most of the time when someone complains about DTML syntax or the learning curve
and so on, the answer is we should code our logic in python if we know this
language. That's what I am trying to do because I love Python.

However, many times I don't know how to import my logic in Zope. 

example:

I wrote a very simple module MyTest.py:
##################################
class SuperClass:
	def __init__(self):
		self.a='This is a in SuperClass'

class MyClass(SuperClass):
	def __init__(self):
		SuperClass.__init__(self)
		self.b='This is b in Myclass'
##################################
In the python interpreter I do the following things:
>>>import MyTest
>>>import MyTest.MyClass
>>>t=MyTest.MyClass.MyClass()
>>>t.a
'This is a in SuperClass'
>>>t.b
'This is b in Myclass'

That's what I expected. Now I intall the package in zope.  I make a ZClass which
only Base class in MyClass. Its metatype is MyClassClass, so it appears on the
popup menu near the Add button.

But when I try to add an instance I get the following message:

Error Type: TypeError
          Error Value: unbound method must be called with class instance 1st
          argument

I guess that the problem is the line
	SuperClass.__init__(self)

==>however I don't understand why it works fine with the python interpreter and
why not in Zope.

Others behaviors of Zope:
suppose i add the following line in the MyClass __init__ function:
self.d='I am d'

No problem when I run it with the interpreter:
	>>>t.d
	'I am d'

In zope:
	<dtml-var "MyClassInstance.d"> 
renders:
	Error Type: AttributeError
          	Error Value: d

I get the right value of d only with the new instances of MyClass. On the other
hand if MyClass has a property sheet, all the instances are updated if change
the property sheet.

==>So again, why these differences in the behavior of ZClass instances depending
of which part we modify (the python Base Class or the Zope ZClass)?

I really love Zope but I prefer code in python. However I hit often the wall
when I try to put the pieces together. I think that speaking about
documentation : clear API docs would be, for me the most important.
What behavior could I expect from the differents parts of Zope. 

Example of docs I find useful with other 'languages':
Python Library Reference
Java API documentation

What's the traceback embedded in the HTML source of the error page?

It will point you directly to where the syntax error is.

Nope -- that doesn't do it.  It does raise a lot more questions,
though.  :-(

Recap: I'm working in a near-fresh Zope 2.1.4 installation.
Everything's in the root folder.  Two objects of interest:

  my_dtml_meth -
    a DTML method that shows the document title, ID, etc.  (because I'm
    curious); the title for this object is "Test DTML Method"

  my_xm -
    an external method that does nothing except attempt to set the
    document title and call my_dtml_meth; the title for this object is
    "External Method: Call DTML Method"

The code has changed a bit since my last post, so here we go again.
Here's my_dtml_meth (the DTML Method):

  <dtml-var standard_html_header>
  id:             <b><dtml-var id></b><br>
  title:          <b><dtml-var title></b><br>
  document_title: <b><dtml-var document_title></b><br>
  document_id:    <b><dtml-var document_id></b><br>
  title_or_id:    <b><dtml-var title_or_id></b><br>
  title_and_id:   <b><dtml-var title_and_id></b><br>
  <dtml-var standard_html_footer>

And here's my_xm (the external method that calls my_dtml_meth):

  def my_xm (self, REQUEST=None, RESPONSE=None):
      RESPONSE.setHeader ('Title', "Title from External Method (try 1)")
      REQUEST.set ('title', "Title from External Method (try 2)")
      return self.my_dtml_meth (self, REQUEST, RESPONSE)

Note that I'm trying two attempts to set the title; my original guess
based on reading the HTTPResponse code, and Michel's suggestion.

Here's what happens when I call these things.  First, my_dtml_meth, as
rendered in Netscape:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Ie. it's possible to get the object's title using "document_title" --
but the standard_html_header uses "title", so my browser's window
advertises this document as "Zope".  Ugh.  Guess I could fix
standard_html_header, but why does it work this way?

Now I call my_xm, hoping against hope that it will override the title of
my_dtml_meth; here's what I get:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Hmmm... identical.  Ie. neither attempt to set the title in my_xm had
any affect whatsoever.  In fact, I just used a command-line HTTP client
to diff the headers and body, and they compare byte-for-byte.

So: no dice.  Better ideas, anyone?

(I think I've learned enough to solve my problem, though: use
document_title rather than title in standard_html_header, and make sure
the DTML method in question has a meaningful title.  But I'm still
curious why things work the way they do.)

Ha, ha!  Silly me...

Internally, my server is known as 'www.waco.ct' and I set up SiteAccess so
that every request containing 'waco' and 'ct' is redirected to the SquishDot
folder.  Of course, this means that I instantly can't get back to the root
folder for any reason.  To fix it, I shut down Zope, removed the SiteAccess
product manually, restarted, and got rid of the offending code.

I offer this as a warning to others interested in SiteAccess--the product
works great, but think a little before you set things up, lest you fall into
the same trap I did.

Thanks. That was the problem. I persevered in my mistake because I saw
'Data.fs' in my zope folder (probably created by my own mistake).

I try to understand the ZODB because i want to process some data in my ZODB
with python. Do you it is the right way to do it?

My main achievement with Zope is part of the MEMS Exchange mentioned by
Michel:

   http://www.mems-exchange.org/z/process/builder/

This is a tool for people to specify the process sequence to fabricate a
MEMS device (= micro-electro-mechanical system, aka micromachine or
microsystem).  They're typically fabricated using the same techniques as
IC fab, but in much more varied ways -- hence the need for people to
specify custom fabrication sequences.  For non-specialists, most of this
tool is meaningless, but it's an interesting demo of how much user
interface you can get away with on the web using something like Zope.

For the record, before we started playing with Zope, I was convinced
that complex user interfaces on the web were all-but-impossible.  Thanks
to Zope, I now believe that complex user interfaces on the web are
merely very difficult.  

We have found no bugs in Python developing this system; we certainly
have our share of gripes with Zope, but I think we've only seen two bugs
that really affected the reliability of our web site.  The first bug was
when Zope 2.1 came out, and we made the mistake of going straight from a
single-threaded, PCGI, Zope 2.0 installation to multi-threaded, FastCGI,
Zope 2.1; things got really flaky.  I think we're now running
single-threaded, PCGI, Zope 2.1.4 and things are peachy.  We really need
to step gingerly back into multi-threaded/FastCGI territory to see how
it behaves.  The other bug was a nasty ref-counting problem deep in the
bowels of mxODBC, so can't really be blamed on Zope.

I've named the python script ba.py.


Is using 'request' proper for the 'Function name?'

If it's the same error we were seeing, then it isn't that Zope crashes,
it hangs, becomes non-responsive.  It's not spinning, it's just sitting
there not answering.  The reason why (in our case) is because of an
uncaptured exception in the medusa code.  Whenever medusa encounters an
uncaptured exception in a thread, it closes it down.  Well, it was
encountering an uncaptured exception in the main listening thread, so it
shut it down... now Zope isn't listening anymore... so it just sits
there.

If you want debug output without using debug mode, add this code to your
start script (reverse the slashes for Win32, of course):

STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE

Debug information will get stored in event.log.

Ok, my syntax error was that I was replacing the username and password with strings and not putting them in

That's fixed.

But I'm still having an error now.

True enough, though I'd have liked to see more, and I'd have liked to
contribute more, too, which is to say, I'd like to contribute at *all*
-- no time for that at the moment, however. Ironically, I'm too busy
using it to improve it.

I find it ironic that JPython is even *slower* than CPython. Curious --
is anybody using it for anything worthwhile?

I'm not disputing the success of these languages. Perl, Python, PHP,
Pike -- they're all quite successful at what they aim to be (*). But
people tend to use languages rather than contributing to their
development. You can't just evolve a language indiscriminantly, which is
why we have Guido and Larry, the benevolent dictators. You can't just
go, "oh, and I added iterated loops today". Every damn little feature
requires at least some kind of ratification process. Languages are much
more susceptible to breaking.

(*) Except possibly Pike. I'm ashamed to say it, but I find myself oddly
attracted to this language, if mostly because of its speed and
interesting resemblance to C. Pike is a good example of "how to make a
powerful language/interpreter system that's also very fast". Pike has
had a type system from the outset, which is a definite edge over Python.

Where?

The type system SIG has a funny intro: "Recently, the types SIG has come
under attack for inactivity, and in response Paul Prescod has offered to
guide the SIG towards accomplishing a single specific goal: to develop
an optional static typing system for Python. The December 1999 archives
of the SIG show the discussion that lead to this decision."

Reading this stuff now. It's interesting. I hope they get it right.
Maybe I'll chip in.

What's interesting about Dylan is that, because it relies on static
information such as type hints and class/method relationships to be
efficient, the developers of Functional Developer (formely Harlequin
Dylan) are facing a design problem related to how they compile programs.
They've actually put all of the various libraries into shared DLLs.
Unfortunately, this means they lose the benefits of the optimizations
that can be made through the use of static compiler information. When
you load up the [latest beta of the] Developer IDE and compile a
program, it consumes a whopping 45MB of RAM. And it's damn slow. The
absence of such optimizations is one reason for this hogging tendency.
So they're planning on providing a "whole program delivery" option
whereby all libraries would be statically linked.

I have several apps where I would rather use Python, but where speed is
so significant that I would either end up writing a lot of the code in
C++ for speed (which is painful due to the lack of integration between
the two languages -- Python classes can't inherit from stuff in the C++
extension, for example).

I also have a database-centric Zope app that causing me headache. The
ZODB is *way* too immature to replace a database right now -- fine for
the kind of stuff that runs on zope.org, not for us. ream

Pardon me for sending off another email in mid-stride. Damn cat :-)

Let me finish the last sentence first: I also have a database-centric
Zope app that causing me headache. The ZODB is *way* too immature to
replace a database right now -- fine for the kind of stuff that runs on
zope.org, not for us. We're actually looking at alternative app servers
and solutions (such as hardwired C++ CGI code) right now. It's a shame,
and I'm fighting it, but we might end up with something like Dynamo.

I don't necessarily say they're _my_ problems, but some people think
they are, and that counts. I don't miss "switch" myself, although I do
miss a kind of enumerated type.

I remember sitting down with Python for the first time create a simple
CGI type thing, and found that I could just do

  def DoSomething(): ...
  def DoSomethingElse(): ...

  DoSomething(eval('Do' + Args['cmd']))

and then call up the CGI using a query string such as
/cgi-bin/foo.py?cmd=Something. Wonderful, and better than any kind of
RTTI.

The list comprehension syntax is cute, but not, I think, so clever.
Perhaps it'll prove to be a nice feature, even a successful one, but
personally I doubt, even with the knowledge in the back of my head of
how this stuff works, that I would instinctively grasp for a
list-comprehension expression as naturally as I grab for, say, a "while"
loop. My head is just not wired that way, and I think the syntax looks
positively alien for Python -- it's not "pythonic".
 
> I don't think you'll see protected members any time soon.

I think Zope's source code is one huge, glowing argument in favour of
having protected members.

I don't particularly take to the idea of a having
mutability/immulatibility property burned into the type itself.

Tuples are immutable, dicts and lists are mutable. Why? Because Guido
says so. Jon Udell, I think it was, has argued that tuples are currently
a redundant element in the language. Why have two kinds of lists? It
just confuses people.

A syntax for declaring the mutability of types would be helpful in
clearing out this mess. For example, you should be able to declare a
dict to be immutable when passed to a certain function call -- ie.,
forcing a copy. Python has no "out" parameter, only "in" parameters that
are mutable depending on the type of the object passed. The syntax I'm
alluding to would effectively give you both "out" and "const"
parameters.

I haven't thought it through. I just think it was potential. Why
shouldn't the translated function refer to other objects? The function
would essentially just constitute native calls to the Py* APIs -- in
effect, a translated function would summarize the runtime calls made by
the interpreter during normal execution. Therefore, non-translated
Python code could just as easily refer to translated code (within a
"translated module", which would be a special object), because the
translator module would construct the necessary proxy object to forward
external calls to the inner code. Or something. ;-)

I'll let you know. ;-)

Thanks Mike,

You are right, root/Users/<usernames> makes more sense than
root/<usernames>.

I looked at what you said, went away and read ZSQL Methods user guide
(again).

Now I'm back.....

>>
 Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.
<<

So my Zope folder layout looks like this :

root
   index_html (default)
   Users (SQL method)
   Flavor (SQL method)

I assume I would also need a DTML Document called "rss" because the SQL
methods can't actually deliver any content to the client browser?

So, if you would be so kind, lead me through how Zope works on this call :

mysite.com/Users/Fred/Flavor/Cherry/rss

Zope starts to traverse the call from left-to-right?

finds "Users", its a SQL method which takes an argument, aha! the argument
is "Fred",

[Does Zope now run the Users SQL with that argument?]

ok, what's left : "Flavor", okay, I have a "Flavor" SQL method here and that
takes an argument too, "Cherry" is that argument.

Finally, Zope finds "rss", if this is a DTMLDocument or something "servable"
it runs it and returns it to the client?

If "rss" wasn't there it grabs the index_html page and serves that?

=======

Thanks for your help.

Like many others I suspect, I see Zope through a cloud. Sometimes I see the
outlines of it and it glimmers! But I just can't grasp a picture of the
whole.

Ah yes, I didn't realize it was in an external method.  External methods
mask the exact error information.

Just import ba.py into a python interpreter *without* Zope and it will
tell you where the error is.

Subject: [Zope] how to tell if displayed in a frame
Message-ID: <38C82A33.B333748A@open.ac.uk>

I have a page that sometimes gets displayed in a frame
and sometimes in the main window.  I want it to be
display differently (with a header) when its  not
in a frame.  Is there a way I can do this?

I don't suppose the name of the target frame
gets passed to the browser does it?

Presumably the only way to do this would be
to do it in client-side code and fecth the header
if appropriate and filter it to make it what is
needed.  Or is it?

Calling a method with () is a python convention.  HTTP has no convention
of calling anything, we just use the convention that the query string
(everthing after the ? in a URL) is a list of name=value pairs seperated
by &.  This is per the CGI specification.

I'm getting a weird invalid character error on my ZSQL Method using
ZOracle... If anyone could help, I would appreciate it:

I have a method with the following params:

    id username password firstname lastname title deskphone cellphone
pagerphone emailaddr soffice_id sprdarea_id

And the following query text:

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values
      (<dtml-var id>,
       '<dtml-var username>',
       '<dtml-var password>',
       '<dtml-var firstname>',
       '<dtml-var lastname>',
       '<dtml-var title>',
       '<dtml-var deskphone>',

       '<dtml-var emailaddr>',
       <dtml-var soffice_id>,
       <dtml-var sprdarea_id>);

When I test it with example feild values, it renders the following
error:

    Error, oci.error: (911, 'ORA-00911: invalid character\012')

With this SQL Used (which if you try in SQL*Plus, is perfectly valid):

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values

Any words of wisdom?

They return query results, which are a sequence of record objects.

Yes.

If you tell it to, check out the 'Advanced' tab on ZSQL Methods. 
(First, don't forget to specify one argument to the method or else you
won't see what I'm talking about).

First it finds Flavor, then it traversed into Flavor, then Flavor find
the next element as its argument (once again, if you tell it to).  So
essentially the answer is yes.

Yes.

If rss wasn't there and it was in your URL then you would get a 404
NotFoundError.  If 'Cherry' is your last argument then yes, it would
acquire the first 'index_html' object that it found, which in this case
is the one in the root folder.

Greetings,


In my experience, to count the size of an array in ZOPE does not require an
external method, simply "_.len(sqlQuery())".  I use this myself in a few places.

I won't try to guess your reasons for not getting sql to count, but surely it
would be by far the simplest way?

Thank you Michel,

After trying your suggestion I came upon this problem:

A white screen with "No Items were specified!" at the address:

   ../BOStorage/manage_delObjects?id=20000428164227

(BOStorage is where the objects are stored and I verified the id#
20000428164227)

Thanks.

Can they do that? How? Something funny in the license agreement?

Subject: [Zope] Use only part of a list sequence? or External Method to Insert ZSQL?
Message-ID: <019301bf8a24$162d8180$5e577e86@jmu.edu>

To all Zopists,

<background>
I have a form that has several dynamically generated options from a MySQL
database.  I have each option using a hard-coded array like
name="mylist[0]", name="mylist[1]", etc..., and keep the value blank unless
selection is made.  Everything is working fine.  In the next page, I will
insert the Authenticated_user as the userid, and another field into a table
in the MySQL database.  When I get to the next page, I have:
...
<dtml-in mylist>
    <dtml-if "_['sequence-item'] != ''">
      <dtml-if "countuser(`AUTHENTICATED_USER`) < 6">  ##countuser counts
user in table
                 will be inserted into tabel here...
      </dtml-if>
    </dtml-if>
</dtml-in>
...
People are only allowed to have 5 entries in the table.
</background>

Here are my questions:
1.  Should I use an External Method that accesses a ZSQL Method to insert
the fields into the table?
(please give me an example of this, it sounds interesting...)

2.  Is there a way to only use the first 5 listings of the sequence?  Maybe
save into another list, then go directly to a ZSQL method insert?

3.  Should I just quit and go home?
:o)

Any help would be greatly appreciated.

   No, it takes a string. Try:

<dtml-call "RESPONSE.redirect('/target?myvariable=xyz')">

Subject: [Zope] how do you do dynamic redirection?



I would like to redirect a user based upon a variable.

<dtml-call "RESPONSE.redirect(/target?myvariable=xyz)">

raises a syntax error.  Does the redirect command only take literals?

redirect takes string.  The correct syntax would be:

<dtml-call "RESPONSE.redirect('/target?myvariable=%s' % xyz)">

Remember, once inside quotes ("") you're writing Python code.

Thanks again Mike.

So my final (I think, for now) question is this :

The whole point of Zope is to get a result back so the URL :

mysite.com/Users/Fred/Flavor/Cherry/rss

is (the way we have discussed it) really a way of saying : "I want an "rss"
document containing information related to User=Fred, Flavor=Cherry.

So in order to get my content out I just have to do some things with
<dtml-with Users> and <dtml-with Flavor> in my "rss" document? (because
these SQLMethods will already have been set up & run as part of the URL
traversal and are ready to give me data?)

I appreciate your patience,

- Ian Sparks.

That would be the last semi-colon ";". Remove it and use in the ZSQL method.
Additionally, instead of <dtml-var  ...>, you might want to consider using
<dtml-sqlvar >, which will assist you in properly SQLising the data.

Message-ID: <00031011262501.26896@localhost.localdomain>

Greetings,


So, I got into work this morning, ready for another day of zoping, only to find
my server not quite responding properly.  When i went to the manage screen, the
tree frame didn't fill, but the right-hand frame was fine.

Hmm, thought I.  Oh well... i can work without it.  So, I clicked on the folder
for todays work and..... 

nothing....


no response at all, not ever a timeout!

Talk to the network admin, we both kick about... and it seems that the ZOPE
server will respond correctly to invalid GET requests, but just freeze on valid
requests.

Further testing shows that it's ONLY when i try to use the management screens. 
The only change in my system recently has been upgrading from NS4.7 to NS4.72.

It's RedHat 6.1, and Zope 2.1.4.

Any idea?

Yeah, that would be very helpful.

As a Zope Newbie, who's developed lots of database stuff in PHP and Perl, I 
am unclear on whether I'm "supposed to" try to make everything an object in 
ZODB.

Say I'm making a repository of documents, like articles or e-mail messages, 
and I expect to end up with 100s of thousands of those, should I 
confidently work on making them all Zope objects, or should I stick with 
mySQL records and/or files in the file system, like I normally would?

As a follow up... i checked another site of mine, and it is now showing

The whole server seems to have locked up.

You don't even have to work that hard, consider what happens:

Let's say that your Users method queries a table that contains two
columns, name and title.  Primary key is 'name'.

Your second method queries a table that contains two columns, flavor and
size.  Primary key is 'flavor'.

Users method is called with 'Fred' as argument, this returns a single
record object.

ZPublisher then tries to find 'Flavor' on that record object, it doesn't
have such an attribute, but it CAN acquire it, so it does.  It discovers
that it is a SQL method and calls that method, *in the context of the
first record object* (keep that in mind...).

The second method is called with 'Cherry' as a argument.  It returns a
single record object.  Now, ZPublisher tries to find 'rss' in that
record object and fails, but it DOES acquire it, *in the context of the
second record object which was found in the context of the first*.

Now you are in the rss method, but you are also in the context of the
second and first result objects, in that order.  So in your method, just
say:

Hi my name is <dtml-var name>.     I'm acquired from the first result
object.
My title is <dtml-var title>.      I'm acquired from the first result
object.
The flavor was <dtml-var flavor>.  I'm acquired from the second result
object.
The size was <dtml-var size>.      I'm acquired from the second result
object.

Note that if a subsequent record object has a column name identical to
that of a preceding record object, the subsequent one is acquired
first.  This means that subsequent results can 'refine' previous ones.

Note that this concept of accessing one object in the context of another
is what is called Acquisition and all Zope objects support it, not just
ZSQL Methods.

--------------------------------------------------

(1) It should work. I have tested it. Nothing
    special is required for the __init__.py file.

(2) Make sure that you have an __init__.py file
    inside your lib/python/Shared/Local folder.
    This file can be empty. Or you can provide
    some __doc__ and __version__ string like
    Digicool people do. But it really can be
    an empty file.

(3) Inside that folder, create a file Chicken.py,
    which contains the following three lines:

    class Chicken:
        def __init__(self, size):
           self.size = size

(4) This python file will not compile automatically.
    It will only be compiled when it is imported
    by some other Zope modules.

(5) To test what you want: create an external method.
    In the folder Extensions inside your Zope root
    (if you don't have an Extensions folder, you
    have to create one first), create a file Test.py
    containing the following lines:

    import Shared.Local.Chicken

    def getSize(self):
        return self.size

    def test(self):
        Shared.Local.Chicken.Chicken.getSize = getSize
        a = Shared.Local.Chicken.Chicken(123)
        return a.getSize()

(6) Go to Zope management screen. Restart Zope.
    (Or shut it down and restart it manually.)

(7) Create an external method with 'Id' = test,
    'Function name' = test, Python module file = Test
    and click on the 'Edit' button, then click on the
    'OK' button. If you don't know what an external
    method is, you've got bigger problems than I
    thought. :)

(8) Hit the 'Try It' tab.

Done! now you can use the external method inside
your other DTML documents/methods. For instance,
you can have a mytest_dtml method with the following
lines:

<dtml-var standard_html_header>
<dtml-var "test()">
<dtml-var standard_html_footer>

and it will print the number 123 when you view it.

I shouldn't have treated you like a 3-year old.
But I guess making instructions as clearly as
possible eliminates unnecessary confusions. :)
We've all been newbies once.

This really isn't enough information for us to do anything except
console you.  Can you do some more investigation?  Try shutting down
your Zope and going to the lib/python directory and then doing this:

bash$ python
Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [GCC 2.7.2.3] on linux2
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import ZPublisher, Zope
>>> ZPublisher.Zope('')

Does that return your top level ('yoursite.org/') content?

Are you using some non-standard modules like SiteAccess?

Yes, I am using SiteAccess.  However, this site has been working fine for some
weeks now.  The site works until you go to the management screens.

Also, an older site of mine (running on Zope 2.1.2) has also shown the same
problem, which started last night.

Two seperate sites showing the same problems at the same time?  Coincidence? 
Not likely.

No you are doing it the right way and it should work fine.

Is there an error and a traceback?

Ha! This must be the most innocent message in a long time. :)

BookS on Zope? Good titleS? Get THEM? Oh boy, oh boy.

There is ZERO book on Zope. But DC people neither confirms
nor denies book deals, this is what I last heard.

All what I need to know in Zope I learned it from the
net, just like everyone else. :) The myriads of loose docs
plus the mailing list does the job. Poorly, but it does
the job.

A good Python book is a must, though, when you want
to get into more advanced features of Zope. O'Reilly's
"Learning Python" by Mark Lutz and David Ascher is
a good bet, well... maybe the only bet. :)

No error or traceback.  It takes me to the "manage_test" page and I can put
the number in manually, and it works.  The crazy thing is, I can force-feed
it the manage_test, like:

<a href="/queries/SearchResultPage/manage_test?theid=<dtml-var
the_id>">link</a>

and the test comes up ok. I don't have a clue on this one...

There are no books on Zope yet.  Mike released a plan some time ago about a
book that he was working on w/ O'Reily.  Maybe he'll give us some new info
:)

I suggest "Learning Python" to get more acquainted with python and then
using the mailing lists and stuff on Zope.org for now.

Later, Nick

Mike,

The problem was on my end.  I was referencing the method instead of the
report page.  Ok, I admit, oops on my part.  Sorry for the trouble. Been
here at work to long.....

I think it's time to go home....it can wait 'till 'morrow....

Thanks for helping my step-back and think alittle.

I don't know what it is, but something had to happen, unless there is
some mysterious kill-your-Zope-on-Mar-8 virus going around.  The one
upgrade to Netscape is unlikely.  But *something* had to happen to both
boxes.  They may be related, they may very well be coincidences, but
neither of them manifested themselves by themselves, that is even more
unlikely.

Greetings Thomas and welcome to the Zope list.

One place you may want to start is WorldPilot (http://www.worldpilot.org).
WorldPilot is a will handle some of your needs. Its a web based PIM with
e-mail, scheduling, address book, and to-do list functions.

What type of document administration are you looking to do? I have some
Notes/Domino experience and if that is your reference point I may be able to
help you find answers based on Notes style solutions.

Thanks a lot for this info...  Well, in that case, I have to be content

No nothing. Really weird. I have actually tried on a Zope instance that
was accessed only by one person and still it will silently stop after some
time. Nothing related to heavy load ...


Could be related to GUF as I was getting some exceptions from GUF but they
were uncorrelated in time.

Thanks a lot Nick

I haven't tried out your suggestions yet but I *hope* they point to the
problem. You write nevertheless that in your case Zope hangs, whereas in
my case the process just dies silently and doesn't even trigger the
manager to restart it. I will try my own supervisor on it and see how it
behaves.

I don't think you need to really get out of your way to crash python. For
someone discovering __getattr__ for the first time and wanting to do some
simple delegation ...

class A:
    def __init__(self):
        self.a=[]
    def __getattr__(self,key):
        if hasattr(self.a,key):
            return getattr(self.a,key)
        else:
            return getattr(self,key)

Wrong but not really bizzare IMO

The story so far...


Well, the second site which appeared to be showing the same problems... isn't. 
It is now working fine.  So, I'm left with just the first site, which is
currently the more important site.

I can traverse normally, until i try to enter a management view.  Then, the
frames arrive, and, upon first attempt, /manage will work, except for the left
frame.  After that, no manage screens work at all.

I do have SiteAccess, but even with __no_before_traverse__, the same problem
occurs.  I can go back to regular pages, and all is fine.

Please do not try to match the start tag and end tag again and again in
zope.

Please come to see the http://zope.org/Members/kentsin

and get the root.zexp for evaluation.

This is a set of method/attributes which will publish the folder's index_htm
document

The methods will generate the doctype, stylesheet, javascript, rdf for the
document.

It can be configure by setting certain attributes.

Hope this will get into the zope mainstream.

Rgs,

Your problem definitely seems to be coming from
SiteAccess. Evan should be able to help you out.

What you may want to do first is to disable
SiteAccess first. Something like:

http://www.whatever.com/__no_before_traverse__/path/to/rule/manage_main'

Then go to the management screen and UNDO that very last thing
that causes SiteAccess to get into infinite loop. If Zope is
not problem, do you have Apache re-write rules somewhere
modifying your URLs?

The first time I used SiteAccess was also my last time.
It was so freaking scary to have a hang-up situation where
you cannot do anything except cry in desperation. :)
Several people have reported problems with SiteAccess.
It's not that I don't think SiteAccess is great: its
concept is great, just that I don't ever want to get
into this kind of scary situation again. :) I am waiting
another few months before I get more reliable version
of SiteAccess or its equivalent in Zope. And no, thanks,
I won't be a guinea pig to reproduce the bug. :)

Subject: [Zope] Zope + Coda = Client Side Zope?
Message-ID: <00030922411300.00635@viking>

Some of the dsicussions in the Client Side Zope thread got me to thinking about
an article I read in Linux Journal sometime ago on the Coda file system. As
luck would have I can't seem to find that issue. Most of the information
contained in that article (now over a year old) can be found in updated form at
http://www.coda.cs.cmu.edu/ . 

For those who've not heard of coda its a distributed filesystem that supports a
variety of the features, including disconnected operation and replication among
multiple servers, that were mentioned in the previous thread. 

I will admit to knowing only the very surface information about coda and throw
this to the list for anyone who has actually used it. Also do any of the DC
folks think that a data store centered around a coda type fs would be doable?
I've been intrigued by coda since I first read the article this may be the
reason to explore further.

Any other thoughts on this?

(I read your post and understand you have this working now)

Just wanted to mention there is another 'shorthand' way:

<a href="/queries/SearchResultPage?theid=&dtml-the_id;">link</a>

A little more compact than the one with <>s.

Server is still up, but I'm wondering if these channels reopen or if
they all close if that's what stops the server?

I can see how this exception is getting left unhandled in the medusa
code, so I'm going to try and catch it and startup the server again.

After trying constructing an entirely NEW zope install, and winding up with not
being able to import the backup of my site, I decided to reboot.

Strangely, everything is working again.

Oh well... at least i've learned some more about the innards of Zope.

Absolutly, but in this case you can just use FileStorage, since coda is
a filesystem.

I attended the Coda session at last year's Linux Expo.  There, the
professor in charge of the project gave a very clear explanation of coda
and how it works.

Useful results with Zope should be immediate, Simply store your Data.fs
file on a filesystem that is replicated by Coda.

There is a more interesting application however, and that is
implementing the actual coda protocols themsleves into a sort of
ReplicatedStorage (I'm not positive if that is the best way to slice the
pie, but it's an idea).  Another idea is to roll a similar or identical
protocol into ZEO, so that not only are Storage Clients and Storage
Server are distributed in a parent/child relationship, but also that
Storage Servers can be distributed in a peer relationship that replicate
each other to provide failover and replication.

Interesting stuff in any case.  I'd really like to hear about someone
who has a success story with Code and Zope using just it's filesystem
capabilities.

Subject: [Zope] WorldPilot Acquisition?
Message-ID: <CC59868A0A76D311B1F50090277B321C1F31BA@VRTMAIL>

I've been mucking around trying to get Acquisition to work with WorldPilot
objects (I want to define methods/documents that can query WorldPilot's
"normal" objects (Events, Address Cards, Notes, Todos, etceteras), and the
collections of the same.  So far no luck (I don't really understand
everything going on under the covers of either Zope _or_ WorldPilot, so I'm
not likely applying pressure at the right points).  I've been adding
Acquisition.Implicit to the hierarchies of just about every object with no
luck so far.

Does anyone have ideas on how to go forward?  Could I alter the "normal"
objects in some way to make them accessible at a higher-level (for example,
if I could get at the objects in a flat collection, I could run my queries
against them, using their types to sort into virtual collections).

I suppose, in a pinch, I could just read the local files and construct a
query against them, but that seems... well, too incredibly hacky.
Incidentally, why does WP use all these custom storage mechanisms?  The
actual objects don't seem too complex, and the interface doesn't _seem_ like
it would require the support.

Ideas appreciated,
Mike

Um, no. Since the code that defines 'layout.table' is also available and
editable, (just like any other object).
So you can not only code the specific header you want into the object, but also
create a parameter which can be used like so:

 <dtml-var object="layout.table">
   <param name="datasource" value="get_above_age">
   <param name="columns" value="Name,Age">
   <param name="table_tagattrs" value=" border=0 bgcolor=green">
 </dtml-var>

I learnt you're doing something similar (from Rik). I have to look at it.

What I'm suggesting is that instead of having to create a product every time
you want a higher level object, we could have a framework so that you could
just create an object that does it. The goal would be to make it easy for
everyone to code their own component objects (or templates, or patterns,
or whatever)

Another thing I would like is that people start looking at 'documents'
differently. Instead of 'my_element_header' and 'my_element_footer', people
think of 'my_element' which takes one or more parameters. (Please don't flame
me, it's Paul who started all this :-)

I guess not. The problem I  have fits the description, but I don't use GUF.
I have the impression though it has to do with busy interactions with a
Gadfly database. Platform: Windows NT, Zope 2.0.1.

Message-ID: <38C8CAC9.C45A5056@nipltd.com>

Just an idea, but if you want to see if it's a bug, or 'non-standard' html
problem in Zope, try copying the 'view source' html of the tree into an html
document and editing it in Dreamweaver.

Dreamweaver seems very good at finding html problems, and you can run tests to
see if any browsers aren't going to like it.

Hope this helps...

Subject: [Zope] trees, hypernews and frames
Message-ID: <38C8C8E0.AB71B295@open.ac.uk>

Sorry, this is involved and takes a lot of words to explain.

I'm building a zope site which also serves HyperNews
discussions.  Apache and Zserver are working well together.

What I have is a tree widget iterating over a folder,
some of whose elements are treated as hyperlinks to hypernews
discussions.  Base articles for discussions are in the
contents of the zope items so .... when  you click
on an element in the tree it follows a link to hypernews
and the hypernews fetches the contents of the "same
item" you just clicked on.  This is a roundabout
way but the only way I know to keep my hypernews headers
and stuff in zope It does all work well but....

My first implementation had a two column table with
the tree on the left and the particular discussion on the
right.  This worked well logically but wasn't too visually
appealing because as you expanded/collapsed tree branches
everything moved around on the page.  So I re-organised
it to use frames - a header frame, then two columns
(tree in one, discussion in the other) and a footer
and this works very well.

My problem is now this - except for the top one
the frames on the page do not include 
what in the former implementation was the header (i.e.
the fancy bit at the top that gives context and doesn't move).
Now its possible and common to access the hypernews discussions
without coming in through the zope home page with the tree
widget.  It is common to do so because when hypernews sends
email it puts a hyperlink to the item in the email which
does just that.  When this hyperlink is followed the page is
fetched from zope but of course the fancy header isn't there.
Since its no longer displayed inside the frameset the
header needs to be displayed as well but isn't.

That's the crunch.  How to get the fancy header served
when its displayed outside the frameset but not served
when its inside.  If it were all in zope then this could
be done by passing a variable value so the page could
know how it was called but hypernews does not pass on
anything like this when it fetches content from other
servers.

Anyone think of a way round this?

Please copy replies to
a.k.heath@open.ac.uk
as I take the digest.

The Guides on http://www.zope.org are available for download and can be printed
out, they feel almost like books if you spiral-bind them ;-)

Seriously, though, they are a bit out of date but certainly a very useful for a
beginner. the order I'd recommend:

Zope Content Managers Guide
Zope DTML Guide (more of a reference really...)
ZSQL Guide (if you want stuff out of a DB)
ZClass Guide (this is probably the worst of the guides and I personally didn't
find it very helpful...)

All available from http://www.zope.org/Documentation/Guides

You can easily turn off ZServer's http server but still leave the other
servers.  Or you can turn them all off except for PCGI.  See the usage
documentation in the z2.py file in the Zope top level folder.

Subject: [Zope] Searching in textfiles
Message-ID: <20000310114307.95496.qmail@hotmail.com>

Hi all!

I'm quite new at this whole Zope thing, so I'm probably overlooking 
something quite trivial.
Here's the deal:
I've uploaded some text files into a folder called "Taglines" there are some 
30 files in all. Now for the problem: How do I search the contents of the 
files?
I made a ZCatalog and I know I have to make an index on "something" but I 
can't find what that something is.
Can this be done? And if so: How?

greetings,
Bart Holthuijsen.

Subject: [Zope] REQUEST vraible methods
Message-ID: <38C8E437.3B1D9AC9@nipltd.com>

Hi,

I'm trying to write a SiteAccess Rule to do some simple virtual hosting helping.
Basically, I'd like to have access from http://www.mydomain.com (which is
virtually hosted...) and from http://zope-host.nipltd.com/mydomain (the actual
Zope host) and have all the management views, absolute_url()'s, etc working
properly.

If you just drop a SiteRoot in /mydomain then everything works fine through
http://www.mydomain.com but http://zope-host.nipltd.com/mydomain/manage just
jumps to http://zope-host.nipltd.com/manage. So I'd like to write my own Access
Rule to do this.

Now, the documentation for SiteAccess mentions a few methods of the REQUEST
object that I can't find documentation for. I was wondering where I could find
complete documentation for the REQUEST object, or how I can find out what its
data and method attributes are?

cheers,

Chris

   You don't need AccessRule for this - just path correct SiteRootBASE and
SiteRootPATH environment variables to SiteRoot. Define it differently on
every server, that's all.

Hmmm,

Not sure I get you, and I'm not sure my explanation was clear... ;-)

I'm only dealing with one server, which hosts several sites.
Each site is in its own directory off Zope's root.
eg: http://zope-host.nipltd.com/mydomain

Each of these sites has its own domain name, which is virtually hosted using
Apache as a front end into Zope. 
eg: www.mydomain.com --> http://zope-host.nipltd.com/mydomain

Now, we typically maintain the sites with:
http://zope-host.nipltd.com/manage
and navigate through the links from there.

However, site owners may maintain the site with, for example:
http://www.mydomain.com/manage.

Also, currently, wherever there's an absolute_url() or the like, such as in the
management screens or in Squishdot sites, links are generated as follows when
accessing through www.mydomain.com:
eg: http://www.mydomain.com/mydomain/manage

If you follow these links, they work through the magic of aquisition but,
through following several such links, you can end up with rediculous URLS.
eg: http://www.mydomain.com/mydomain/mydomain/mydomain/mydomain/manage

I think SiteAccess's Site Root's are designed to sort this out. You drop a Site
Root with a path of / into the /mydomain folder.
Unfortunately, this site root also affects access through
http://zope-host.nipltd.com/manage and so if you try and follow the link to
http://zope-host.nipltd.com/mydomain/manage_workspace you in effect get
redirected to http://zope-host.nipltd.com/manage_workspace 'cos the Site Root
strips out the /mydomain.

Also, if you go to http://zope-host.nipltd.com/mydomain/, all the links are
broken for the same reason.

Which is why I want to use an Access Rule instead and make it a little cleverer.

Which is why I'm trying to find out what methods/variables there are in the
REQUEST object, which doesn't appear to be documented very well ;-)

cheers,

Chris

Actually that's not _completely_ true.  The Quick Python book has a
chapter written by Brian Lloyd and Amos Latteier on what used to be
Bobo.  It's still a useful intro into the idea of object publishing with
Zope.

   Do not pass any SiteRoot* variables in this domain and pass both in
www.mydomain.com.

   SiteRootBASE => http://www.mydomain.com
   SiteRootPATH => /

That should do all tricks you want.

Richard,

The equality check on AUTHENTICATED_USER will always fail because your
comparing an object with a string.

You need soemthiong more like :

<dtml-if expr="AUTHENTICATED_USER.getUserName()=='zope'">

One tiny datapoint.

I set up a small Engineering Change Request system w/ zope and
PostgreSQL 6 months ago.  It has been running flawlessly [1] ever since.
Machine uptimes are in the mid-2 digits (i.e. about every 2 months we
have to rearrange things in the lab).  Note this is a very low load
application.

As for perl/python stability, you could go back and see how often
new releases come out and use that as an argument.

Okay, I think I'm starting to understand more, btu I'm still not quite there yet
;-)

When you say 'pass any siteroot variables' what do you mean?

Do you mean pass them from Apache?
Do you mean set them as properties somewhere?
or something else....

Well there goes this weekend. ;-) I've grabbed the Postscript copies of some of
the coda documentation and I think I'll attempt to set something up this
weekend if I have a chance. My "lab" setup includes a Linux server, a Linux
workstation, and a Windows 95 workstation, so I'll be able to check so measure
of "cross-platform-ness".

The idea of a ReplicatedStorage mechanism is what I was (mis)firing at with the
original question on feasability.  As I have stated before on this list some of
my background is Lotus Domino/Notes and this could bring Zope close to some
functionality of a Notes Client/Domino Server interaction. (I won't bore the
list with details if anybody wants some I'll be glad to do it outside the
bandwidth of the list, unless a lot people want it :-)

It looks fine, so far and i downloaded it.
I'm not sure if i understand the Workgroup-sharing correctly - can
different users participate at the same Address-book or Calendar?
I mean does it support a shared calendar for several people?

If yes, this Product is my way to go and Zope and WorldPilot will get another

I'm not entirely sure here - the client wants something that would be

to use LINUX and Zope. As i can tell, Notes/Domino may be exactly what

   Exactly this. How do you access Zope from Apache? Proxy, FastCGI or
PCGI? They all have different methods to pass vars (and I afraid proxy
doesn't have such way).

   Properties will be used for all domains, that why I said set path
property empty in SiteRoot.

You can set any terms you like in your use license. Whether they are
enforcable in a civil court is a separate question. For example, all
through the '80s Oracle Corp. had a restriction from including Oracle
product in any product comparison, such as benchmarking. 

Sometime in the early '90s Oracle Corp. lifted that restriction. It may
have something to do with the fact that Oracle was finally running fast
enough to look good next to Informix, et. al. 

Microsoft picked up on this mode and had similar restrictions inserted into
SQL Server licenses. I didn't know about that part of Microsoft's license
until I heard Larry Ellison talking on a radio interview, blasting Uncle
Bill for this dispicable practise!

Okay, we use proxy :( . Also, the URLs are rewritten by Apache so that all the
relative links don't go to http://zope-host.nipltd.com/mydomain/*whatever* as
opposed to http://www.mydomain.com/*whatever*

What I was thinking is to write a Site Access rule as follows:

If the host name is zope-host.nipltd.com:
	do nothing
else
	<dtml-call "REQUEST.setURL(path='/')">

Maybe storing zope-host.nipltd.com in a property of the root level folder too.
My only problem is finding out what the host name is.

Will REQUEST.environ.HTTP_HOST be set by the time an Access Rule is called?

Richard,

The equality check on AUTHENTICATED_USER will always fail because your
comparing an object with a string.

You need soemthiong more like :

<dtml-if expr="AUTHENTICATED_USER.getUserName()=='zope'">

Subject: [Zope] how to tell if displayed in a frame
References: <38C82A33.B333748A@open.ac.uk>
Message-ID: <38C9047B.53DAD777@vt.edu>

It can be done in server-side code, if you know when you put the
document in a frame or not.
Something like the following might help:

In the document in question, do some code like:

<dtml-if in_frame>
...display definitely in frame
<dtml-elif not_in_frame>
...display definitely not in frame
<dtml-else>
...default display, which may be the same as one of the above
</dtml-if>
You will probably want to factor out the duplicated content into
subsidiary methods.

Now, if you want the default view, call it as <dtml-var mydoc>

If you want it in its frame view, call it as <dtml-var "mydoc(_.None, _,
in_frame=1)">
You might want to make a dtml method called e.g. myframedoc with the
above code so you can call it as a url.
<frame src="myframedoc" title="blah">

Another way is to call the document in HTTP:get format in the frameset.  
like: <frame src="mydoc?in_frame=1">

Thanks for solving the immediate problem Phil - another UK Zopista - 
there's a few of you out there ! I think I've had help from all of you in 
turn :-)

However I think this reveals a basic problem with the syntax which is 
causing me grief and presumably there are others like me out there.

I would expect an object to behave consistently wherever it was used - so 
if it renders/returns/evaluates to 'zope' inside a dtml-var I would expect 
it equally to render/return/evaluate to 'zope' inside a dtml-if.

If it doesn't then surely we have an inconsistent syntax. How do we know 
how any object is going to behave inside a dtml tag ?

Any comments ?

Why do you want to do this? Have you thought of why it is there?

Create a folder 'Foo' with an index_html method in that Folder, and a 'bar'
method. The index_html document contains a relative link to bar
(href="bar"). Next, go to the URL:

  http://your.server.name/Foo

Note the lack of a trailing space. If you now follow the relative 'bar'
link, you'll neatly end up in http://your.server.name/Foo/bar.

However, had you removed the BASE tag, your browser would have attempted to
load http://your.server.name/bar instead. This is because the relative URL
is offset against the last slash in the URL. The BASE tag however, tells
your browser that the actual URL of the document it is showing, contains an
additional slash.

So, unless you have a really good reason, you don't want to remove that
slash. And if you do, you have to make absolutely sure that the visitor will
never end up on a URL of which the browser needs to be notified is different
from the actual URL.

Richard,

As someone earlier today on the list said, "if it's in quotes it's python"
(or something similar).

Basically Python rules apply when using any expressions in zope dtml-var and
other tags.

Well, that's how I think of it.

Message-ID: <013601bf8aa5$e2733060$0a00000a@smartway>

Hi all !

I try to learn Zope...

I have a very simple ZClass myClass.
This Class has few properties (let's say title:string, description:text).

I would like this class to have 2 methods that can render its instances
simply.

Let's say DTML Methods :
render1
render2

I've made thoose two methods in my Class :
ex :
render1 :
Title : <dtml-var title><BR>
Description : <dtml-var description fmt="structured-text" newline_to_br>

and render2 :

<B>Title</B> : <dtml-var title><BR>
<B>Description</B> : <dtml-var description fmt="structured-text"
newline_to_br>

(the examples are stupid !)

But when I call the methods from the index_html of my content folder like :

<dtml-var "myClass1.render1">
or
<dtml-var "myClass1.render1()">
or
<dtml-call "myClass1.render1(myClass1)">
or
<dtml-call "myClass1.render1(_.None)">

None of theese shows me the infos :(((((
Sometimes, i have AttributeError, sometimes Authorisation PB :(


Please help !

I still think it's an inconsistent syntax.  It should be possible (by
overriding __coerce__, I think?  I haven't had time to look this up yet)
to make the == operator do something different.  AUTHENTICATED_USER is
often used as a string (at least what I've seen of it ...)

Also, "if it's in quotes it's in python", why do I need to do _.str()?  
why does dir() not work?  It seems like some pretty horribly munged sort
of python...

In-Reply-To: <Pine.LNX.4.10.10003101041100.26820-100000@jeff.goingv.com>
Message-ID: <NDBBLENPLCPAHKODFHNGAEMHCNAA.morton@dennisinter.com>

A number of people have expressed a desire to have XSL support in Zope. The
projects I am working on also seem to be needing the application of XSL, and
whilst we can (and will) use some external XSL processor, it would seem that
a 'cleaner' solution would be to have XSL support directly in Zope.

I originally came to want to use Zope because I needed a tool that allowed
the manipulation of a persistant tree of objects; my prototype was done in
XML, but it needed persistance, an interface, and a programming language,
hence the use of Zope. Even having only XPath support would be an extremely
usefull way for packaging up simple 'queries' on the Zope database.

Ive been looking around at the Python XSL implementations and the
FourThought 4suite is looking pretty damned good, especially considering
their goal of eventual ODMG 2.0 support. Zope desparately needs some
standards compliance, even if only for the buzzwords.

The question on my mind is: how much do other people want XSL in Zope?

Im willing and able to put some $$$ up for a bounty on this. Is anyone else?

I guess Id also like to heard what DC has to say about this; whether they
are willing to have an external group contribute/merge a key technology into
their codebase, and if they have any preferences about who this group might

Heres what Uche Ogbuji of FourThought has to say about Zope
http://www.pythonjournal.com/volume1/issue2/col-intranetpython/

The Zope Dope
Digital Creations, fresh from a capital infusion, has given Pythoneers their
first complete native Web application platform in Zope.  the "Z Object
Publishing Environment".  Zope is similar in scope to Cold Fusion or
SilverStream, but open-source and python-powered.

Zope accumulates many bits and pieces of a successful Intranet site.  It
incorporates a database management system with object extensions (which,
unfortunately, doesn't yet support the Object Database Management Group's
specifications) as well as facilities for developing template Web sites, an
application framework, a CGI mechanism for handling HTTP requests for
objects, an HTTP and FTP server, and a comprehensive application framework
to tie it all together.  Z Templates are developed using a proprietary
XML-based language, the Document Template Markup Language (DTML).  ZTML does
make some departures from the XML community in such areas as style-sheets,
but it is hoped that Digital Creations or other contributors to Zope will
work to close that gap.

Zope is a synthesis of Digital Creations' many earlier products, such as
Bobo, Principia and PCGI.  Bobo has been especially popular among Python/Web
programmers, and Zope looks poised to retain the tradition.  If Zope can
move a bit closer towards object database and XML-processing standards, it
is likely to be quite popular outside the Python community as well.

Subject: [Zope] External Method to view ZSQL Record
Message-ID: <00c901bf8ab6$b38ce6e0$5e577e86@jmu.edu>

To all Zopists,

I would like to use an External Method to access a record field from a ZSQL
method by referencing another field in the record.  If I set the External
Method up such as:

def viewfield(self,reference_field,search_value,field_value):

where:
reference_field = So that I can tell it the field I want to reference
search_value = The value of the reference_field to query
field_value = The value of the returned field, that I was looking for

Do I use a "return" or a "result" or something else?  I still don't have a
handle on python yet, so I'm not sure what to put on the second line of the
method.

Thanks for all the help so far, and thanks for the help on this, in advance.

Subject: [Zope] MySQLDA / MySQLdb problems
Message-ID: <NDBBLBELNHAPHBBCOIFDGELDCBAA.ewalstad@energywright.com>

Hello all,

I have tried everything that I can think of (& a lot of what some of you
could think of) to get MySQLdb to compile and install.  I have had no luck.

So, I am now trying to install MySQLDA (a step back) and am still having no
luck.  I'm hoping that the MySQLDA problem is related to the MySQLdb problem
and that one of you will be able to point me in the right direction.

Here's what happens when I try to install MySQLDA:

First, the 'make -f Makefile.pre.in boot' script seems to work fine, but
I'll include the output anyway, just in case.

As far as I know, I don't thing it's possible in Zope. I'm very interesed in a
way to do that, so I thought about a possible solution:
- make an empty class in python, e.g. MySuperClass;
- when creating your ZClass, make MySuperClass one of its Base Class;
- if you want to modify your ZClass Base classes, just add super classes to
MySuperClass and create/modify and __init__ method in it:

class MySuperClass(NewBaseClass01, NewBaseClasse02...):
	def __init__(self, parmeters...):
		NewClass01.__init__(parameters01)
		NewClass02.__init__(parameters01)
		...
It sounded a good idea to me and worked fine in python. However I got:
******************
Error Type: TypeError
Error Value: unbound method must be called with class instance 1st
argument
******************

Not very useful but who knows. Let me know if you figured out a solution.

Hello,

I am trying to display a sequence of numbers with next to each of them the 
cumulated value of the previous ones. Thus, I was trying to declare a variable 
buffer to add at each cycle the value of the new number. But I can't figure 
out how to create a variable.

Can somebody tell me how to declare such variable?

Thanks,

Hi,

I've always noticed the same thing, over a period of months. I'd also like
to know what it signifies. Is the list stored in the ZODB, and is this
therefore indicative of the kind of performance than can be expected with 6k
records? Or a relational table? It's not very impressive, makes the member
list something to avoid, and it's undoubtedly fixable...

Even if it gets "fixed" right away, it'd still be useful to know what the
problem was.

Subject: [Zope] Trees with DTML Methods?
Message-ID: <38C9562C.8B33C8E3@pacsg.css.mot.com>

http://www.zope.org/Members/anthony/tree-coding-tricks
"How-To: Some Neat Tricks with dtml-tree"
seems to imply that I can use trees on things other than ZODB objects.

But I've been banging my head against the wall on this for some time,
and I can't figure it out.

Here's what I've got:

An index_html document:
<dtml-var standard_html_header>
<dtml-call "REQUEST.set('eid', '1000')">
<dtml-tree id=eid branches_expr="GetEmployees(eid=eid)">
  <dtml-var eid>
</dtml-tree>
<dtml-var standard_html_footer>


A DTML Method called GetEmployees that returns test data:
<dtml-if "eid == '1000'">
  <dtml-return "[1001, 1010]">
</dtml-if>
<dtml-if "eid == '1001'">
  <dtml-return "[1002, 1003]">
</dtml-if>
<dtml-if "eid == '1010'">
  <dtml-return "[1011, 1012]">
</dtml-if>
<dtml-return "[]">


What I get is an infinitely expanding tree of two pairs of 1000's:

- 1000
    + 1000
    - 1000
        + 1000
        - 1000
            + 1000
            + 1000
+ 1000

What I don't understand is how the stuff from branches_expr is supposed
to change things around.  And, not coincidentally, that seems to be the
problem with this code....

Thanks for any help.

worldpilot.1.0.4 fixes it.
I included WPsmtplib.py and WPimaplib.py and use them now instead of the
originals to avoid dependency problems in these modules

I took a look at the imap code. it basically complains that
the SELECTed folder is not read writable.
As far as I can remember the problem may be that UW IMAP locks your
folders when they get selected.
Possibly you're accessing that folder with a different client
concurrently?

Let me know if that's the problem, since I have heard about this problem
a few times, and I thought it was a locking issue on UW IMAP.

If not we'll have to look into it.

Cheers,
Ryan

You are using a version of MySQL that is too new, I think.  I haven't seen this
one in a while, but I think I recognize the error messahes.  Try dropping back
to 3.22.25 (3.22.26 might work, but I know that .25 works and >.27 does not).
Send me a private email if you need a copy of the rpms.  I am sure I have thenm
somewhere

It is not inconsistent because all things behave consistently within
quotes and consistently without quotes.  You just have to know the rules
of each case.  Granted, it's not pretty, but it's consistent.

It's never used as a string because it is not a string.  You can't use
the word 'string' unless you are talking about python expressions.  DTML
does not have types, you must rely on python's expression machinery to
get down to thinking about the types of objects.

This is for security reasons.  We've overridden many of the built-in
functions like str and dir with our own so that DTML programmers cannot
do mean and nasty things, intentionally or unintentionally, from DTML.

It doesn't use the Catalog.  It's a plain Zope folder.  This means that
the folder object, including it's dictionary of childer, is loaded into
memory every time it is accessed.  This is the inefficient part. 
Folders were never meant to contain this many objects.  This is not
neccesarrily a lack, Linux directories are not that efficient either. 
Try putting 6000 files in one ext2 directory and then type 'ls'.  Pack a
lunch.

What is needed is a Folder object based on a more efficient storage
mechanism, like BTree.

I'm all for this.

And here comes the but.

But, 4Suite is not suitable (i.e. doesn't compile) for Win32 at the moment
(that's from the horses mouth, well Uche at least).

There was talk of win32 binaries but they seem to never have materialised.

I sopke to Uche today, and supposedly there are people who have had it
compile under win32. Im tracking them down at the moment. 4Suite may not be
suitable at the moment, but not because there arent win32 binaries.

I suppose line 1125 of mySQLmodule.c is something like:

Yes!  But I think that the concurrency might be happening from
Zope/WorldPilot?  I.e. that it is submitting another command prior to
the first results?  I ran (the patched) imaplib.py by itself (it has a
"sample session") which gave "reasonable" results...

Or, it might be an instance of the way recent UW imap daemons deal
with the maildir issue, copying files to the local user account from
the mail spool...  (see documentation, which I'm not yet sure that I
understand; but then again, I'm a research biostatistician, not a
sysadmin/www-master...).

I replicated it using UW imap locally on the linux (debian) box.

Maybe I'll try firing up Cyrus -- does anyone know if it "drops in" in
the same way that UW Imap does?  (i.e. install and go...).  Debian's
got it, so maybe I can do that...

Now I'm confused. You have to restart the Zope server after untarring the
package. Does WorldPilot show up on the Product Management page? If not maybe
it was unpacked into the wrong place. Did you set up the directories that are
listed in the INSTALL.txt. One change that can be made to the instructions is
the permission settings on the created directories. You can set them to 755 and
user to the user that runs Zope and group to its primary group. For example I
run zope with user jack.users so my directories look like this:

drwxr-xr-x   2 jack     users        1024 Feb 17 21:33 sessions
drwxr-xr-x   3 jack     users        1024 Feb  1 23:04 storage
drwxr-xr-x   2 jack     users        1024 Feb  1 23:04 user

The first time installed WorldPilot I think I had a permission error and ended
up with a broken product in the Product Management section.

Hope this helps.

Hi Patrick -

What happens if one manually deletes a file that is part of a transaction
involving many objects/files? How would transaction boundaries be enforced
on a filesystem? I am interested in hearing your thoughts on the issue
since it seems you have already done some work on it.

The following test was done with the WorldPilot Note facility and I suspect
would be similar in the calendar. I have three test users on the system
tester1, tester2, and tester3. I logged in as tester 1 and created 3 notes: 1
private, 1 public, and 1 confidential. I then added tester2 in the sharing page
with browse and read access. Tester3 only got browse access. Tester1 sees all
three notes, tester 2 the public and confidential, and tester3 the public. If
you have resources that need scheduling you should be able to set up userids
for the resource and let it have a calendar that is open to appropriate people
to read and/or edit. There may be a easier way to do this and maybe Ryan will
let us know if/when he sees this. :-)

I've not had a chance to work much with Exchange Server but if memory serves it
doesn't do much more than a standard IMAP server in the sense of
mailboxes and shared folders. It provides support for calendaring and address
books (with client support for LDAP, another of the things on my list of things
to learn.) So beyond that it depends on what they want to do. 

Good Luck!

Yep, although this would greatly improve my assertion that unix dirs,
like zope folders, are not efficient enough to handle 6000 objects, it
would not effect my assertion that zope folders need a more efficient
storage mechanism.

I know this is probably what you meant Patrick, I just wanted to be
explicit.

In this light, I have experimented with a BTree folder.  I posted the
code to zope-dev eariler this week.  Anyone get a change to see it? 
Anyone interested in actually improving it?

I have done nothing on this, unless you count daydreaming. ;>) At one
point, I had idly asked if anyone thought this might work, expecting
that some knowledgeable soul would immediately shoot the idea down.
Surprisingly, both Jim Fulton and Hans Reiser seemed to see that it was
in the realm of possibility, but not easy.

Of course, you have identified the hard part. Back in December, Jim
Fulton had the following reaction (below). Afterward, someone else at DC
told me that when Jim says it "getting transactional semantics right
might be a tad tricky" he means your head will explode. :)

Still ... since Linus Thorvalds has refused to add the complexity of
journalling to the Linux buffer cache, the people hacking on reiserfs
and other journalling filesystems, have been forced to implement their
own mechanisms for keeping track of dirty data. So one wonders if these
might be adaptable in some fashion, much as they are used to support
high availability network filesystems like Intermezzo, which exploits an
existing filesystem as a cache and wraps around it.

So, in answer to your question, I have no idea. ;)

===========

[Jim Fulton]
Would you imagine using the reiserfs as a ZODB storage?
If one was going to use a file system as an object store, 
then the reiserfs would be attractive due to it's effective
support for small files. Is this what you had in mind?

The ZODB has a well-defined "storage interface" that should
make implementation of a reiserfs- (or just an fs-) 
based storage reasonably straightforward, although getting
transactional sematics right might be a tad tricky.

Jim

One possible approach here is to have your proxy add a magic path element to
the path, sending http://www.mydomain.com/PATH to
http://zope-host.nipltd.com/PROXIED/mydomain/PATH.

Then have an Access Rule which says:

If "REQUEST.path and REQUEST.path[-1]=='PROXIED'" then "REQUEST.path.pop()"
and "REQUEST.setURL(path='/')".  There doesn't have to be a real object
called PROXIED, it's just a flag to be recognized and discarded by the
Access Rule.

I've just had a few frustrating hours trying to work out what was going on
with Zope.

It stopped allowing the addition of DTML-Methods. The connection would just
hang waiting for the Method to be created (also happened with DTML-Documents).

Turns out that /tmp was out of space temporarily. -- the disk that Zope
was running on had plenty of space.

It'd be nice if it would return low disk space errors rather than go off
into never-never land.

When in doubt, read the fine manual.  The _actual_ syntax you are using is::

  <dtml-var name="AUTHENTICATED_USER">

which can be abbreviated (and is, by almost every Zopista) as:

  <dtml-var AUTHENTICATED_USER>

The "name" form of the var tag is the "preferred" one, for the types of
applications DTML is really designed for: simple scripting of objects built
in Python.  It does several "automagic" things with the name:

  - If it is callable, calls it, passing the current object, the
    current namespace, and the REQUEST;  it then replaces the object
    with the result of the call.

  - If it has a string coercion (__str__) method, calls that and
    replaces the object with the result.

This behavior is the Right Thing (TM) for simple scripting;  but it _isn't_
Pythonic (the automagic stuff smells more Perlish, really).

The "in quotes" version is really::

  <dtml-var expr="AUTHENTICATED_USER">

but can also be spelt (and mostly is)::

  <dtml-var "AUTHENTICATED_USER">

The "expr" form of the var tag evaluates the Python expression (in this case,
to the object AUTHENTICATED_USER).  For fairly obvious security reasons, the
evaluation takes place inside a restricted namespace, without the usual
builtins;  the "safe" builtins are made available as members of the
"_" namespace.

The simplest disambiguation possible is to cease using the shortcut forms, and
always spell what you really want:

  <dtml-var name="AUTHENTICATED_USER">  <!-- DWIM: give me text!!! -->

or

  <dtml-var expr="AUTHENTICATED_USER.getUserName()"> <!-- DWIS,NWYTIM -->

Hope this helps!

I now just take my log files and run it thru a script to correct the

I got a quoted version of the object if I made

It does not evaluate the tags and quoted all < with &lt; and so they all
showed on the browser.

What rules determine when it will be quoted?

Also, I got the same result if I have

<dtml-var "folder.obj">

I can work around with

<dtml-with folder>
<dtml-var obj>
</dtml-with>

But how can I workaround "this"?

Actually, the Members roster is a bit more efficient. It uses caching to
store the results. This was added only recently, before the roster was
offline for a while because it was taking too much resources.

What happens is this:

If the cache has expired, or is empty, we do go through all 6000 Member
folders, and check wether or not they are listed. From listed Folders (just
over a 1000 now), we store the id and title in a list. This list is sorted
on id. Next we store the total number of Members found.

Then, we loop over the 6000 Member objects, and check wether or not they
have been active in the past two weeks. The number of active accounts is
also stored.

Together with a timestamp, this info is then stored as a volatile dictionary
attribute, and returned.

A next call to Members will return this cached information. Timeout of the
cache currently is 60 minutes. So, the batched pages and the searches use
this cached information.

There are a few reasons why it still may be slow:

1/ The cache has expired or is empty: we have to fill it again.

2/ The cache is per-thread. It isn't persistent, and therefor not shared
between threads. Your request could hit on thread first, your next request a
different thread, and then have to wait for the cache to fill twice.

3/ The volatile attributes don't hang around as long as I expect them to.
Maybe the object cache is a bit too aggressive, I haven't figured this out
yet. I haven't been able to get the cache to stay around for more than 20
minutes, but it is hard to verify and debug with 7 threads. I am not sure
about this one, because in the course of some extra testing I got to see
cache older than 20 minutes again.

4/ The dictionary containing the cache may be coming from swapped memory.
Currently, the Zope.org process grows quite large. This may have to do with
the up to 42000 Folder objects loaded into memory at any time. The Members
Folder holds references to 6000 Member Folders, and there can be up to 7 of
them (7 threads). This is an area where a BTree based folder would _really_
help.

5/ Plain network lag. Check other pages on Zope.org.

6/ CPU is hogged. The rendering of the ZQR is very expensive. If it runs,
the whole of Zope.org suffers. I am seriously considering disabeling it.
People really onlly need the pre-rendered version. I was testing just now,
had to wait way too long, and noticed someone was looking at both the normal
ZQR (rendering from XML), and the print preview version. The Members roster
came from cache.

I CCed David Kankiewicz on this, so he knows =)

1000 is still too many to be efficient in a regular folder.  You're
right that a BTree is probably the way to go here.  I didn't know about
the caching efforts, it seems like you went through some hoops to come
up with a better solution.

I think that we should seriously look into or have someone in the
community look into my BTree folder efforts to come up with a better
solution.  Depending on when I wake up tommorow, I'll see if I can fix
the various bugs in BTreeObjectManager and make an alpha release.

The only big question I can think of is, should BTreeObjectManager
replace ObjectManager?  Obviously not at first, but we should maybe look
into replacing OM with a more efficient form.  Looking strictly at
performance, I don't see any reason why this should be the case.  In all
cases, a BOM should be faster than an OM.  BOM are not any less
efficient in resource consumption either, and they are written in C, not
python.  Zope's BTree implementation is also very well tested, and
written by Jim, 'nuff said. ;)

FWIW, I am running the latest stable release of MySQL, MySQL-3.22.32-1

Works for me. Especially if it results in a more up-to-date version in
pre-rendered style. Pre-rendered is about 6 months old, IIRC.

I imagine Zope is like anything else (basically) you would run in a
chrooted environment. Give it the things it needs, and it should be
fine.

You may want to have alook at the Zope Product code for Zope Studio. I added
methods to the Application class, exactly what you want (watch it, long URL,
you may have to reconstruct):


http://cvs.zope.org/cgi-bin/cvsweb.cgi/ZopeMozilla/ZopeStudio/ZopeProduct/Zo
peStudio/ZopeStudioRDF.py?rev=1.2&content-type=text/x-cvsweb-markup

The important bits are 'import OFS.Application', and to assignments to class
members in OFS.Application.Application:

  OFS.Application.Application.zsTreeRoot = zsTreeRoot
  OFS.Application.Application.zsContainerRDF = zsContainerRDF

Note that the 1000 items is a sorted list of (id, title) tuples, _not_
Folder object references.

Once the cache is filled, we only have to display the precooked numbers,
take one _.len() of the listed members list for display, and have dtml-in do
it's magic on the afore-mentioned list.

The problem lies mostly in the fact that we have to access each and every
Member Folder to check if it is listed. Even if we use a BTree, we'd have to
load every Folder into memory. The same for the User objects in acl_user.

This is a side effect of using Extension Classes. From ExtensionClass.stx:

  Overriding methods inherited from Python base classes

    A problem occurs when trying to overide methods inherited from
    Python base classes.  Consider the following example::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            Spam.__init__(self,name)
            self.favorite_color=favorite_color

    This implementation will fail when an 'ECSpam' object is
    instantiated.  The problem is that 'ECSpam.__init__' calls
    'Spam.__init__', and 'Spam.__init__' can only be called with a
    Python instance (an object of type '"instance"') as the first
    argument.  The first argument passed to 'Spam.__init__' will be an
    'ECSpam' instance (an object of type 'ECSPam').

    To overcome this problem, extension classes provide a class method
    'inheritedAttribute' that can be used to obtain an inherited
    attribute that is suitable for calling with an extension class
    instance.  Using the 'inheritedAttribute' method, the above
    example can be rewritten as::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            ECSpam.inheritedAttribute('__init__')(self,name)
            self.favorite_color=favorite_color

    This isn't as pretty but does provide the desired result.

--
Another way, and I used this, is by bypassing the method binding, by
accessing the unbound method. The above example could also be:

        def __init__(self, name, favorite_color):
            ECSpam.__init__.im_func(self, name)
            self.favorite_color=favorite_color

The propertysheet variables become class variables, which are persisted as
well. So when you retrieve an instance, the persisted class that described
the behaviour of that instance is taken from the ZODB, and the new persisted
class has the .d attribute there.

In your python class however, .d is a instance variable, it gets set when a
new instance is created and __init__ is called. And exisiting instances
don't get __init__ called again, after all they were initialized already.
They only get their current state restored, and that state never included
the d attribute. Only on new instances, where __init__ is called, does d get
set.

You could get around this by making d a class variable, by adding d='I am d'
to you class definition. Alternatively, you could use the __setstate__
method, it is called when the instance is retrieved from the ZODB. It
revives the state of the object, and you'll have to remember to call
Persitant.__setstate__ as well:

    def __setstate__(self, state):
        Persistent.__setstate__(self, state)
        if not hasattr(self, 'd'):
            self.d = 'I am d'

'this' is an object reference, and it is being stringified. So the source is
returned, HTML quoted.

What do you want to achieve? Calling itself? ot very wise, as it would cause
an infinite loop..

If you want the source, do <dtml-var PricipiaSearchSource> and give the
Document a Proxy Role of Manager.

Well, here's a STUPID_LOG_FILE and a DEBUG.LOG during a crash.  I've
annotated the DEBUG LOG` as to when I think the crash occurred.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

I guess thats not the point here. Sure you can use POST for forms as
well
as GET. You can even "construct" A form-like URL for GET using
?var=value&var2=value
but you cannot send something inside forms without javascript over a
href-tag.

There is a really good Howto on the zope.org website that explains in detail how to
call a ZSqlMethod from an external method, and how to parse out the results
afterwards.  Follow those instructions and you shouldn't have any problems.  Your
email spells Extensions as 'Extentions', so make sure that this is not your problem
(probably just a typo, I know, but I thought I would check).

This might be a better idea. I'd use an external file, however.

User will alway read from file, is fast (shared locking). A cache update

This doesn't solve this. It's not the surfing of all those folders, it's the
accessing of the Members Folder itself. It's that folder that holds the
references of 6000+ sub Folders.

It is necessary when you want to call a DTML Method or Document from a
Python expression and you want that DTML Method or Document to be able
to look things up as an attribute of a 'client' or in your current
namespace (or any namespace you provide).  You can omit it when you are
using a DTML Method or Document _by name_ in DTML.  Note that:

<dtml-var IManager>

is the same as:

<dtml-var name="IManager">

and:

<dtml-var "IManager()">

is the same as:

<dtml-var expr="IManager()">

So most people use the first and third shorthand forms to use an object
by name and to execute a python expression respectivly.  When the DTML
Engine sees that you are using an object by name, it tries to do clever
things, like detect if it is a DTML object and to call the method and
pass the namespace 'magically'.

When the DTML engine sees that you are using an expression, it assumes
you know what you are doing and does no magic for you.  Therefore, you
must explicitly pass in the namespace.

> I'm also very unclear
> as to just what the 'client' is, especially since most of the examples
> I've seen involve passing in None for the client.

The 'client' is an object that you want to use as a namespace.  For
example, if DTML Method 'IManager' wants to find the name 'img' you can
pass a client object, and the method will try and do a getattr(client,
name) (in this case, name being 'img').  If you pass a namespace, then
it will try and do a namespace[name].  If neither of these succeed, it
will look for the name in the optional list of keyword arguments you can
provide.  If that fails, it raises a NameError.

The reason why it is None in most cases is because you want your method
to look things up using the Zope DTML Namespace (affectionately known as
'_').  In some special case however, you may want to explicitly provide
some other object.

This is single handedly the #1 obfusication in Zope and the most
frequently asked question.  We, of course, did not obfusicate this on
purpose.  When DTML was first concieved it worked by name only, so the
behind the scenes magic was acceptable and intuitive.  Later, we added
python expressions, and the ugliness of calling DTML Methods and
Documents became aparent.

Message-ID: <Pine.BSI.3.96.1000311155818.539I-100000@twirl.bitdance.com>

I've got a simple CatalogAware ZClass.  (CatalogAware is the only
class I added to its inheritance list.)  Everything seems fine,
but if I access an instance of the ZClass through the Catalog by doing, say,
getobject(data_record_id_), and then inspect the 'id' property of
the returned object, instead of getting the id of the object I get
the id of the folder in which the Catalog lives.  When I create
class instances, the 'id' in the meta-data is correct.  If tell
the catalog to update itself (or tell an item listed in the catalog
to update itself through the catalog management screen), then
suddenly the metadata id is also the id of the folder enclosing
the Catalog.

Is this a bug, or am I doing something stupid?  The object appears
under its id in all of the management screens, including the 'indexed
items' tab of the Catalog.

Hi DTML Gurus,

I am a newbie with DTML and i am trying to do the following with this script

1) using the subdirectory RegisteredUsers, check if a ZClass object of type
Player exists in the RegisteredUsers directory with an id that matches that
in the Request ( a form from the client ). This currently doesnt work for
some reason and i get the else case even if the object does exist.
2) In the else case i am then trying to create a new object of type Player
 a ZClass object defined in the GameSite product ).  I am creating the
object correctly in the correct place but the next bit of setting the
properties of  the player object does not work, and the object properties
are blank.

HELP !!

I have checked all the documentation for zclasses, dtml faq etc.  Can any
one help?

Is  there an easier/better way of achieving what i am trying to do, or am i
barking up the wrong tree ?


<dtml-with RegisteredUsers>

<dtml-if REQUEST['new_user_name']>

User currently exists

<dtml-else>

New user

  <dtml-with "manage_addProduct['GameSite']">

    <dtml-with "Player.createInObjectManager(REQUEST['new_user_name'],

I think I heard somewhere that it's now equal in speed to CPython, but 
I'm not sure. People use it to script Java components and such. It seems
to be reasonably popular for things like that in Java-land.

[snip explanation why open-source like collaboration is harder for languages]

It's hard for language *design*, yes, but it's less hard when you're doing
language implementation (for instance a faster one), and it's easier still
when you're writing libraries and such. And it does happen for language
design as well -- the Python static type design is currently being fleshed
out (in bursts) by the types-SIG (though of course Guido does final
approval about what goes into Python proper).

Hm, I'm not entirely sure how to find it other than digging through the

You'll find some of my silly messages too. :) The types SIG came quite
a long way after Guido proposed closing it down for inactivity. It's a bit
more quiet now, I believe.

There are various tools out there for Python which do offer this kind of
functionality, though, I think? Check at the vaults of parnassus sometime:

Why not use a relational database? Is it too immature that way?

I think I see what you are trying to do here, but I don't think
DTML works that way.  The array reference is a python expression,
so you have to go to an expr.  But if you just enclose the above
in quotes you'll be testing whether or not REQUEST has a non-null
new_user_name variable.

One way to do what you want would be (tested):

<dtml-with RegisteredUsers>
  <dtml-if "new_user_name in objectIds(['Player'])">
  User currently exists
[...]

REQUEST is on the name space stack, so new_user_name will be found
without having to refer to REQUEST explicitly.  'objectIds' returns
a list of object ids, and the argument gives a list of meta_types
of the Ids to return.  So this call results in a list of just the
Player ids.  The python 'in' operator checks to see that the
left hand string is a member of the list of strings on the
right hand side.

Note: you'll run into some interesting issues with your planned
setup of the number of players gets large (say that large is several
hundred) due to practical limits on the capacity of Zope Folders.

Well, you may want to take a look at GUF and perhaps the (RealSoonNow) the
Portal Toolkit, but they may both be overkill for your application.
It depends on just what functionality you are trying to put into
your Player objects.

I forget which How-To I got this out of (maybe the CatalogAware

name is (copied from some of my own code):

propertysheets.<your-sheet-name>.manage_changeProperties

Since your cut and paste dropped some stuff there, though, that may
be what you have, in which case I don't know why your properties
aren't getting updated.  Though you might try adding the _.None,_
arguments to the beginning of the call.

I'll repeat my question; why not use a relational database? Do you
need an object database? How is the ZODB too immature?

I'm having some trouble with it too, but perhaps that's just not being
familiar with the concept yet. But at least it looks less horrid than
some map()s and such.

Why so? I myself think Zope's source is an argument for explicit interfaces. :)

Well, tuples can be used as dictionary keys, lists cannot.

Forcing a *copy*, implicitly? But Python works with reference semantics
only? It's be nice to have a way to declare stuff immutable, I think,
but I'm not sure how often one would need to use it. There's something
to say for knowing something's a tuple, instead of having a list and
having to know whether it's immutable or not. Though perhaps that's
not a big problem in practice.

But that might result in a lot of incomprehensible code. I'm not sure if 
I'm in favor of having 'out' parameters anyway. constness as defined in
C++ is also tricky, as it infects code; everything that touches it
needs to be const-correct. Python tends to be less strict in this area.

[optimized statically typed modules calling classic python modules, why
is this tricky?]

Yes, it is doable but tricky in combination with static typing. See
the types-SIG for more info; I believe Guido has some messages on that.

Strange problem here - likely not related to Zope directly.  When our
content guys edit the DTML through the Zope management interface in IE 5.x,
the pages are properly displayed in IE 5.x (and assume 4.x).  However, in
Netscape, some pages do not display properly.  After running the DTML though
a code validator, the results indicate that the H/DTML is correctly
formatted for IE/Netscape 3.x and above.  We're aware of the normal
differences in table formatting, for example, between the different
browsers.

However, viewing the pages in Netscape 4.x, the source has all the "<" and
">" replaced with question marks.  This has been tested in Windows 98/NT 4.x
and Linux RH 6.1.

Now, I'm open to suggestions.  I am tempted to think this is a result of
some encoding issue, or perhaps  IE 5.x's handling of extended characters
but I'm at a loss.

This is likely some silly setting that we've overlooked but I thought I'd
check here first.

I've seen that behavior under Linux Netscape when viewing some sites.

Having worked with C++ for a long time, and later with Java,
I can tell you just how much I hated the whole thing about
data "encapsulation."

The whole mumbo-jumbo stuff about data hiding has one and one
single purpose: divide the programmers into engine programmers
and app programmers, so the engine programmers and exercise
full control over app programmers. It has more to do with
MONEY and corporate POWER CONTROL than with technology.
The private/protected keywords are an enterprise feature...
designed for big companies.

And generations of students are taught into this stupid
c**p about "data encapsulation." Funny thing is, many actually
buy the idea, get burnt for a few years and refuse to
acknowledge they are being burnt ("if it is mentioned in
textbooks, there must be a reason... it must be good for me..."),
and only then to realize much later... hmmm.... maybe
"data encapsulation" should be done by convention and not by
syntax.

Yes, another thing that I consider to be stupid in C++ is the
overuse of const, or its use at all. Again, generations of
programmers are taught into this thing about usage of const,
and buying into it without questionning.

Python uses references for object parameters in function calls.
It can also return tuples. That's enough. Really.

Keep Python simple. The role of Python is CP4E (Computer
Programming For Everyone.) In Java or C++, you have to type
all the extra stuff about public/ private/ protected/ void/
abstract/ static/ synchronize/ final/ const/... before you can
do something. I know many people that live in that world and
refuse to simplify their lives... well, then again, I also
know people that lives in the Perl world and insist that Perl
is a very readable language. :)

So to keep all start tags and end tags in the same object.

I can do that for a folder by making the method call index_html and call the

But I want to publish anyobject by adding this method to it:

abc/publish

will warp abc with the apropriate html codes which traditionally in zope is
done by header, var, footer. which might result in the opening tags in
header and end tags left in footer.

Subject: [Zope] Redirection problems
Message-ID: <20000311202916.B8706@magellan.midsouth.rr.com>

Right now, visitors to my site at http://www.centralchurchyouth.org go
through the following redirection:
http://www.centralchurchyouth.org (running IIS)
	to
http://www.centralchurchyouth.org:8100/ (running Zope)
	to
http://www.centralchurchyouth.org:8100/Home/ (the real home page)

This works in Netscape but doesn't work in IE. The user gets all the way
to the third page but it doesn't render. Upon further analysis, all of
the absolute_url calls (like "<dtml-var "stylesheet.absolute_url()">"
produce http://www.centralchurchyouth.org/xxx instead of
http;//www.centralchurchyouth.org:8100/xxx, so the page has a broken
logo, etc.

I think it has to go with the HTTP session between IE and
http://www.centralchurchyouth.org:8100/, but I'm not sure what. Using
wget also returns a correct page.
Surely someone has come across this issue.

[snip]

Having worked with C++, Python, and Object Pascal for a long time, I
tend to agree, with a few modifications:

- encapsulation helps keeping the code self-documenting -- nobody can
accidentally access hidden members;

- it aids documentation tools in that visibility rules can be seen as
metadata -- "source navigator"-type object browsers can categorize
members (methods and data) into their various protectedness; and

- most significantly, hiding data and replacing direct access with
clearly defined accessor methods lets you control access (such as
synchronizing access from multiple threads) and also provide behaviour
-- often data is calculated on demand rather than stored, and often
related objects must be notified when data is changed.

Python doesn't have accessor methods, but uses __setattr__ and
__getattr__() instead, which is less intuitive -- a code browser cannot
easily infer the access interface from the class definition alone -- and
certainly slower -- but also more flexible. 

I'm a big believer in pure-code interfaces, keeping data hidden and
restricting all reads and writes to accessor methods; languages such as
Dylan and Object Pascal fortunately have accessor-method support built
into the language, so referencing an attribute foo.name would actually
be resolved by the compiler into a call to foo.GetName(). Python doesn't
really need this, since its attributes are all dictionary-stored.

Btw, as for private data members that are very specific to an
implementation of a class, Ada95 solves this quite elegantly through
packages, which are similar to C++ namespaces. I don't remember if Ada
has language-assisted accessor method support.

Const is overrated but often useful. Given C++'s absolutely antique
object paradigm -- heap-based objects that aren't garbage-collected,
meaning you end up dabbling with pointers *a lot*, or use confusing
reference-counting smart-pointer template classes that go all over the
place -- I like pass-by-reference better.

I'm absolutely annoyed with C++. This is one reason:

  class Foo;

  class Bar
  {
    Foo F;
  };

  class Foo
  {
    Bar B;
  }

This, of course, won't compile -- the class Foo is undefined at the time
Bar is declared. This means that a class A cannot contain a member of
another class B if B already contains a member of class A, unless one of
them stores the member as a pointer reference. This certainly screws up
any reference-counting smart-pointer scheme, or at least makes it bloody
hard to keep simple.

Readability and verbosity are not the same things. Java is at least an
improvement on C++'s readability, but it is occasionally perhaps too
verbose. But not compared to, say, Dylan, which has keywords like
"required-init-keyword"; in spite of this, it's a great language once
you get used to it.

I rather like Borland's Object Pascal myself. It's suitably verbose to
be readable, strict enough to catch most trivial errors in the
compilation phase, statically-typed enough to perform really well, and
just plain likeable. It doesn't have operator overloading, parameterized
classes, multiple inheritance, or synchronized members, although it does
have interfaces, static, abstract, const, and member visibility
constructs. Here's the above snippet in OP:

  type
    Foo = class;

    Bar =
      class
        B: Bar;
      end;

    Foo = 
      class
        F: Bar;
      end;

(And this compiles.)

Indeed, but do I need to remind you that we're still at version 1.52?
:-)

And as for your argument that OSS boosts language implementation, true
in theory, but sitting down with a compiler and changing it, or building
a compiler from scratch, is a daunting and time-consuming task. I have,
certainly, thought about building a native-code compiler for Python. But
no time right now.

Your comments are well received. I hope I can put my own comments to
shame in the future by committing some of my resources to the Python
effort. As for the types-SIG, I've read through Guido's latest proposal,
and found it so-so; I have some comments about the syntax -- which IMHO
is heading in the right direction, but I feel it's still quite
unpolished, like the new "decl" keyword and the very odd, un-Pythonic
"->" operator. Other than that, it looks a lot like I had in mind
myself.

Interestingly enough, I'm discussing this with Jon Udell on his Byte
newsgroups (go news.cmpnet.com). I'll quote something I wrote in this
discussion, slightly edited for clarity:

<quote>
I can't easily tell Zope that objects of type A refers to objects of 
type B (mutual relationships), and that objects of type B should not 
be deletable as long as an object of type A is referring to it 
(referential integrity). The only kind of relationship Zope knows 
about is containment, a parent-child relationship. There is simply no 
other way for an object to refer to another object.

Consider the case of news articles. Let's say articles should be able 
to hold multiple sections of text, as well as images. Assuming we use 
Z Classes and not Products, two solutions come to mind: Either (a) let 
an article be a descendant of Zope's folder or object manager 
classes, and thus contain any such sub-data as objects -- a design 
which currently is the most useful, but which has its shortcomings -- 
or (b) let sub-data exist as objects elsewhere in the ODB, and have 
string attributes on the article object that refer to their names, 
eg. an attribute "Illustrations" of type "lines" containing image IDs 
such as "mayor.jpg", "airplane.jpg" etc. This is obviously ugly -- 
for example, these image objects could be moved or removed and the 
article object would never know. As for dividing article texts into 
multiple sections (page 1, page 2 etc., with appropriate headings), 
this is obviously pretty simple with scheme (a), but in the case of 
(b), the text could exist in one large attribute, and some sort of 
page tagging system might be enforced -- or we could go all the way 
and do XML. So far, with these solutions, we'll survive. Cracks begin 
to show when we start thinking about organizing authors, 
publications, and document flow.

Zope doesn't provide a framework to solve this things. Equally worse 
is that the ZODB hierarchy is so easily polluted with things that 
don't belong there. You end up putting a lot of objects in the root 
folder because they're needed globally -- and anyone who has used 
Zope will tell you that a folder becomes unwieldy and disorganized 
when it grows past 20+ objects. (Case in point: Personally, several of 
my Zope sites have a root-level Utils folder containing oft-used 
External Methods, because they tend to pollute the whole namespace.)
Zope needs a multiple-root, "multihomed" hierarchy. Z Classes must
be able to exist anywhere, not just in the one Products hierarchy.

No, although that's a clever trick. Hey, do it again! :-)

What you cite above may mirror the effect of an enumerated type, but it
doesn't contain any meta-information about the type itself: That is,
FOO, BAR, BAZ are integers. They will fit into any integer expression
and can be passed to any function taking integer arguments. The function
won't balk if you pass a value from another "enumeration". Another
problem with the above is that there is no way to ask Python to
enumerate the values or names in the sequence, because its values are
part of the top-level namespace -- I don't like that kind of namespace
pollution.

Instead, perhaps, this:

  class Enum:
    def __init__(self, Value):
      self.Value = Value
    def __int__(self):
      return self.Value

  class DeadParrot(Enum):
    FOO, BAR, BAZ = range(3)

  def PetShop(P):
    if int(P) == DeadParrot.FOO:
      print 'It''s resting.'

  D = DeadParrot(DeadParrot.FOO)
  PetShop(D)

...But hardly elegant.

And that makes sense to you? I don't know the historical significance of
tuples in Python -- I know the mathematical meaning, but Python tuples
aren't quite it -- but it smells a lot like an interface that has been
fit to the size of the implementation. A lot like, coincidentally, a
procrustean bed. (Coincidentally because the term has popped up a lot
lately; see the Byte thread.)

I think the idea that mutability as a behaviour is distributed among

(No, it would not -- it would effectively give you both "out" and
*pass-by-value* parameters.)

The alternative is returning dictionaries or tuples, is it not? Maybe
I'm not thinking in a Pythonic vein. Maybe

	A, B, C = GetABC()

is more immediately grokkable than

	GetABC(A, B, C)   # assuming these are "out" parameters

Well. Sure it is. Damn, I think you're right. ;-)

Subject: [Zope] Calling a Z SQL Method directly
Message-ID: <6rwvn824kh.fsf@franz.stat.wisc.edu>

I am a little confused about how to call a Z SQL Method directly from
within a DTML document or a DTML Method.

The application is web-based access to a bibliographic database.  I
have one Z SQL Method that looks up publications by author names, or
by words in the title, or by keywords.  I set up a search interface to
that method.  I am now trying to modify the DTML Method for generating
a report from such a query.  I have read the Z SQL Method User's Guide
but apparently I haven't understood it completely.

To make things definite I will describe a simple case.  Suppose I look
up one author's name.  The Z SQL Method is called search_author.  The
columns it returns include the "id" for each reference listing, the
"type", the "year", and the "title".  I have also created a Z SQL
Method called return_authors that takes a single argument "id" and
returns the names of the authors, one per row, in the correct order
for the publication.  Another Z SQL Method, return_journal, also takes
an "id" number and returns the title of the journal, the volume and
number, the beginning page and the final page of the article.

While I am processing the results of search_author in the DTML method,
I would like to be able to call return_authors and return_journal
directly.  It is not clear to me how I do this.  I had hoped that I
could use a dtml-in tag to call these methods while I was within
another dtml-in but either I am misinterpreting the effect of dtml-in
or I haven't got the sequence right.  What I was trying looked like

<dtml-in search_author size=50 start=query_start>
 ...
        <tr>
          <td><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
	  <td><dtml-in return_authors start=query_start>
                  <dtml-var name>;
              </dtml-in></td>
              <dtml-in return_journal_info start=query_start>
                  <td><dtml-var title></td>
                  <td><dtml-var vol null=""></td>
                  <td><dtml-var bpg null="">-
                      <dtml-var epg null=""></td>
              </dtml-in>
        </tr>
 ...
</dtml-in>

I was hoping that the <dtml-var id> from within the <dtml-in> loop
would be propagated to a call to return_authors or to return_journal.

I understand that I can use a URL to call the Z SQL Method but I am
hoping I can do it "inline", as it were.

I would appreciate any suggestions.

Douglas,

ZSQL methods can be passed arguments.. e.g.

<dtml-in expr="return_authors(id='123')">
...
</dtml-in>

In the case that the 'id' value you want to pass in comes from REQUEST
or another namespace, you can use it:

<dtml-in expr="return_authors(id=id)">
...
</dtml-in>

The _.render() method will do what you want:

  <html><head>....</head>
  <body><table><tr>...

  <dtml-var "_.render(this())">
  </tr>
  </table>
 ....
  </body>

you need a folder called "import" in the same directory as your zope
installation.  Then go into zope, click "Import/Export" tab at the top,
and enter 'filename.zexp' in the "Import file name" field.

then click "Import".

That should be it!

I'll take a stab at this:

Quantity of data doesn't tip the scales towards Zope or SQL.

If you have small units of data that change frequently, SQL, using a
non-transactional storage like BerkleyStorage, or packing frequently are
all reasonable approaches.

If you have a number of large (multimegabyte) files, the filesystem is
probably the best place for them, with something like LocalFS.  Also
nice because you can have a "real" ftp server serving the files, but
still use zope to reference them.

If your data expresses several many->many relations, a relational
database may be the solution, but don't underestimate the power of
Zcatalog. for data expressing one->many relationships, ZODB rocks.

In your example, I would use the ZODB because emails are always
hierarchical, and use Zcatalog to let people slice & dice it. The
articles would depend on what views you need to put on them and what
metadata you want.

You can also do some super neat stuff with ZODB+SQL, as the very
illuminating 
Zope Question : Virtual folders / URL's thread is illustrating.

I've done some really neat things (like securing the management screens)
with SiteAccess that I couldn't dream of doing any other way.  I've
never seen SiteAccess perform in any unadvertised fashion.

Anything that lets me have less than hundreds of zopes is a good

Let's say I have a TinyTable populated with some data.  I have a DTML
method that displays it all pretty like.  What I do *not* want is
someone seeing the TinyTable itself, so I give "access contents
information" to anonymous, but deny "view".

AFAIK.

This might be possible. I'm checking the IMAP code. Possibly we'll need
to use EXAMINE on some spots instead of SELECT.
Maybe there's a race situation which would explain why it works for some
and for some not.

If heavy copy operations are involved then that would support the race
situation.
We use debian, too, so we'll try to replicate the behaviour here, too.

Cyrus is better scalable and has cached indexes. furthermore mails are
stored in individual files instead of in mailbox files.

Use the DateTime Object, in python:

Py$ from DateTime import DateTime
Py$ DateTime() > DateTime('Jan 1, 1999')
1
Py$

in DTML:

<dtml-if "_.DateTime() > _.DateTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Calling the DateTime object with no arguments means 'now'.  It accepts a
number of different date formats.  I just made this one up and it
happily accepted it.

In DTML, _.DateTime is synonymous with the global value ZopeTime.  So
the Second example is equivalent to:

<dtml-if "ZopeTime() > ZopeTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Hi,

we started a new service for our online newspaper, that is served by a Zope
server. (http://rz-anzeigen.de) We currently experience the problem, that the
machine serves really well and also during the high traffic times. But
sometime in the early morning the Zope process crashes. Now I like to know if
it is possible to get some more specific out from the Zope server when it
crashes. Can I activate some kind of logging to monitor this, or something
else that helps me to deal with this? Or is my only option to start the Server
    form the shell and see what traceback I get?

Bye, Oliver

I have this

    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltecimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

IIRC the logic that puts in BASE tags ignores the port number.

It was a simple change (removing an if section) somewhere to fix it.

I did it in old bobo-based app so it may have changed by now.

Jo,
Thanks for your C expertise.  The changes you mentioned were all that was
needed to get the MySQLmodule to compile and the MySQLDA to work.  I now see
the ZMySQL Database Connection in my list of available items in Zope!!! (big
smile).

I will eventually want to get Andy Dustman's MySQLdb connection to work,
because it is multi-threaded.  But for now I will stick with what works,
learn how to tie Zope to MySQL and THEN go for the upgrade to MySQLdb.

Anyway, thanks again for taking the time to solve my problem.

Eric.

Subject: [Zope] Problem with Images
Message-ID: <LOBBJLLPAJLLCKOOOAGFOEADCCAA.gelhaar@compuserve.com>

I've got a problem with the image class. I use Zope 2.1.4 (downloaded from
http://yyy.zope.org/) with Windows 98 second edition.
Let me give an example:
1. I create an image object head_1 and upload an image "cat". Everything is
fine.
2. I upload an other image "dog". Almost nothing happens. The image is not
there. But something has changed: The size properties. What ever I do, I do
not get the right picture, I will see always "cat" but always in different
sizes, the size from the last uploaded picture.
But that's not all.
3. I delete the image object head_1
4. Create a new one, let's say head_2 and give it an image "dog". I see dog.
5. But now, when I rename the image object from head_2 to head_1 I will get
again the old picture "cat".
This scenario is always the same, regardless what I do:
* shutdown the database in between
* clearing the undo buffer
* new installation
* hide the python installation dir
* delete the database

I played around with the lib/python/OFS/Image.py. But I experienced enough
with Zope thus I know Python. What ist wrong with me or the Image class.

Help

I've been asking this list the very same question for quite a while.  There
are a few debug How-Tos that may help, but it's all very dependent on you're
configuration as to how much extra work will be necessary.  Can you give me
more details of your configuration?  What are you using for connection, are you
going through Apache, if so using what service (PCGI,FCGI,HTTP_Proxy)?  

We have several sites up and running with Zope and have found that when there
is /manage activity occuring during a time of moderate traffic we have frequent
Zope restarts, it can't stay up more than 5-20 minutes.  To date I've found no
reliable method of tracking what is causing these, though I've created a bunch
of monitoring and debuging tools to try.  These tools are not written up yet,
but I'd be happy to send out an explaination if you would like.

It is also very easy to create code that will crash or loop the Zope server,
these are easer to find since usually as soon as the object is called Zope
reacts adversly, crashes, slows, etc.  The problem using logs for this is log
entries are usually written post completion.

Good luck.

This is almost certainly because your browser has cached the image.
Try clearing your browser cache.  Or better yet (because sometimes
clearing the cache on some browsers doesn't seem to completely
clear it), try loading the thing from a browser that hasn't
looked at that image before, and you will probably see the correct
image.  At least, that's how it worked for me when I ran into this.

Do you know about STUPID_LOG_FILE?  Put that variable in your
environment when you start Zope, and Zope will write some stuff
to the specified file.  This info may or may not show something
when Zope crashes, but it is worth a try.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

I've followed anser's How To on "Apache and ZServer (NOt CGI)"
and now I have Zope served thru Apache via module ModProxy and the
SiteAccess Zope Product.

Fine, But Now I want to make Zserver only accept connections from
a set of known IP address (ie that where my apache server runs)

Any ideas how you do this? I can see there are options to say
which ports it listens on but no mention of restricting the
IP addresses it allows to connect.

Thanks

Jon

Ive been having a similar problem. The problem lies not with Zope, but with
your browser and its cache. As long as you are trying to retrieve the image
from the same URL, your browser will grab the cached image rther than the
one from Zope. I havent delved into this, but I think adding some content
expiry info to the 'view' tab might be necessary. Either that or change your
browser settings.

You can connect to the database from the mysql command line utility?

ZServer does not do this interally, however there is a very secure and
popular program called tcpwrappers that does.  Your system probably
allready comes with tcpwrappers.

How to configure it to work with ZServer I don't know, but it shouldn't
be hard.  Consult the tcpwrappers docs.

If you are using Linux, this job is best done with
the firewall itself (like ipchains.) Otherwise it
is not very secure.

That being said, inside Zope itself, you can put in your
index_html (or equivalent)

<dtml-if "REQUEST.REMOTE_ADDR != '127.0.0.1'">
  <dtml-return "''">
</dtml-if>

Of course, you can return a nasty message, or redirect
the request to some other web addresses by using
<dtml-var "RESPONSE.redirect(...)"> :) If you are using
SiteAccess, you can put a hook at the root folder to
bounce off anyone that you don't like.

The REQUEST variable holds other environment variables
that might be of your interest. You can either use

<dtml-var REQUEST>

to print out the variable content, or simply append
/REQUEST to your URLs when you are browsing a Zope
site:

http://your.site.name/yourfolder/yourpage/REQUEST

Subject: [Zope] Generic User Folder Gotcha
Message-ID: <20000313105937.B4444@bob.sesgroup.net>

Just thought I'd let people know about a small gotcha in the GUF.

If you do not have a user folder in the root directory and then create
a GUF in a subfolder using cookie-based permissions it will lock you
out of that folder.

GUF works fine in this situation if you use basic authentication just
not with cookie based. The problem is that in cookie based authentication
method it never checks whether you are the super user or not. It works fine
if you have a user folder in the root becuase it then goes and checks it.

I tried some code to get around it but didn't really have time to fix it
esp when it is trivial bug/feature? to get around.

Anyway just though this might save some people some time along the way.

Oh and thanks to Zen GUF is a fantastic product !

Cheers,

Benno

Take a look at the dtml-try tag in the dtml documentation.

Message-ID: <B059671903C6D211A0D500C0F0301C792B2697@kubrick.mop.no>

Like so, for example:

	<dtml-var "MyDate.toZone('GMT')" fmt="ISO">

Date-time math is very simple with Zope's DateTime objects. DateTime
supports fractional, C-type clock values -- 1.0 is one day, 0.5 is half
a day, 1 / 24.0 ~= 0.0416 is one hour. So,

	<dtml-var "(ZopeTime() + 1).toZone('GMT+5')" fmt="ISO">

gives you the time tomorrow, adjusted to GMT+5. You can use named time
zones such as "US/Eastern".

Helmut,

I doubt it.  It's probably a username/password/databasename issue.

My suggestion would be to set up mysql to accept a null login (no
username, no password), create a database in there called "test" and
connect with the connection string "test@localhost"

I don't think this is a bug in WU or a concurrency issue, I think it's a
funky design decision in imaplib.py

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import imaplib
>>> server = imaplib.IMAP4('X.X.X.X')
>>> server.login('michel', '******')
('OK', ['LOGIN completed.'])
>>> server.select('Public Folders/Mailing Lists/Zope Folder')
Traceback (innermost last):
  File "<pyshell#8>", line 1, in ?
    server.select('Public Folders/Mailing Lists/Zope Folder')
  File "C:\Program Files\Python\Lib\imaplib.py", line 468, in select
    raise self.readonly('%s is not writable' % mailbox)
readonly: Public Folders/Mailing Lists/Zope Folder is not writable
>>> 

server in this case is a Exchange box.  There is nothing in section
6.3.1 of rfc2060 that says this should fail.  The imaplib authors
however seem to have felt otherwise, which is why there is an optional
second argument to IMAP4.select():

def select(self, mailbox='INBOX', readonly=None):

Passing a true value to the readonly argument will allow you to select
the mailbox, as shown:

>>> server.select('Public Folders/Mailing Lists/Zope Folder', 1)
('OK', ['964'])
>>>

Try the DebugLog, this is an as yet undocumented feature of Zope:

http://www.zope.org/Members/mcdonc/HowTos/DEBUG-LOG

This will show various state transitions of requests.  This helps
pinpoint, for example, if your problem is a ZServer or an application
issue.

Subject: [Zope] Python or C Library error?
Message-ID: <NDBBLBELNHAPHBBCOIFDKEMGCBAA.ewalstad@energywright.com>

Well, I thought I had it working...

I am trying to get MySQL to work with Zope.  I installed ZMySQLDA and was
able to make a connection to a database.  I was even able to make an SQL
method that added records to the table.  However, when I added a method to
lookup a record in the table, I get the following error when I "Add and
Test" it from Zope:

Error, exceptions.ImportError:
/usr/lib/python1.5/site-packages/_mysqlmodule.so: undefined symbol:
Py_InitModule3

This is the same error I got when I tried to install MySQLdb.  That's why I
tried to install  MySQLDA instead.

However, I can't tell if this error stems from C or from Python.  I don't
know much about Python (the book I ordered isn't here yet), but it looks
like the error is starting there.

If anyone has run into this error before, or has a clue as to how to fix it,
please let me know.

OR, if you have a working Zope/MySQL combo and wouldn't mind sending me a
copy of your '_mysqlmodule.so' binary, maybe that would do it?

Thanks,

Eric.

This is kind of a distressing message Tony, we'd very much like to see
any code that can easily crash Zope.

Yeah ;) But whats with comparing wether we are between hour xx and hour
yy 
every day? Or even between 0:00 and 1:15 every day...
This comes up with very strange hassle with DateTime() and strings and
int() 
and so on...

Or is there a better way?

I've never used MySQLDA without MySQLdb.

I would try to follow the steps in the howto that deals with installing
mysql (including the steps for installing MySQLdb) in order to get the
thing working.

It sounds like you couldn't compile MySQLdb because you didn't have the
right libraries for MySQL.

I saw that, too, but wasn't sure if it behaves the same, because a few
lines further up if that parameter is true then it uses EXAMINE instead
of SELECT. I haven't made it yet back to the RFC's to check in detail
what the exact difference is between the two. If EXAMINE is OK for 
write operations as well, then that would be fine. But it sounds like
it's intended for following read only operations only. I'll check it
out...

Cheers,
Ryan

DateTime works at one one-thousandth of a second resolution.  Hours and
minutes are no problem.

No hassle that I can see, no more so than any other kind of object that
would do this.

There's mxDateTime, which I believe works similarly to DateTime.  I
don't think one is any 'better' than the other.

Subject: [Zope] RFC: Flaws in Structured text
Message-ID: <B059671903C6D211A0D500C0F0301C792B2699@kubrick.mop.no>

I would like to outline a few problems, based on
observations of real-world usage, with Structured text.
Comments are appreciated.

As much as I like the format, the current syntax is either
too loose, or the transformation logic too dumb, resulting
in text that does not come out quite as expected. There are
workarounds for all such problems, but authors and editors
aren't aware of them, and continually make the same mistakes
over and over again.

Here are a few gotchas:

- Lines starting with the text number-dot (eg., "1.") are
considered to be bullets.

  Problem: In other languages, and sometimes in English,
  this is a valid non-bullet introduction. In Scandinavian
  languages (Norwegian is the language of my country), for
  instance, "1." is an oft-used way of spelling "1nd" or
  "first" ("2." for "2nd" or "second", and so forth). My
  experience is that this occurs frequently.

  Solution: Avoid transforming such paragraphs into bullets
  when they occur adjacently to valid non-bullet sentences,
  and only apply the transformation when the number is
  higher than the preceding paragraph. Validate the number
  itself -- today you can write
  
    43423. Something
    
    24324. Something else
    
  and it's still transformed into 
  
    <ol><li><p>Something</p><li><p>Something else</p></ol>

- Lines starting with dash-space (eg., "- The") are also
interpreted as bullets.

  Problem: As with number bullets, this clashes with non-
  English conventions. At least in Scandinavian languages,
  quotes are often given using a preceding dash. Here's an
  actual example, translated to English for clarity:

    - Pooh, said Rabbit kindly, you haven't any brain. - I know, said
Pooh humbly. 

  Solution: Make this feature optional.
  
- Em dash sequence ("--") usage clashes with definition
lists.

  Problem: People, including me, frequently use an ASCII
  form ("--") of the em dash ("-"), in the absence of this
  character in the 7-bit ASCII character set. (Actually,
  what *I* want is an en dash, which ISO provides.) This
  transforms into a HTML <dl></dl> list, even when the dash
  occurs late in the paragraph.
  
  Solution: Only transform paragraph to definition list if
  the dash sequence follows the first, dot-terminated
  sentence, like so:
  
    This is a definition term. -- and this is the definition
    itself.
  
  Not sure whether this is ideal. It would likely break old
  stx documents. Perhaps a "force literal" control character
  can be introduced, like the "\" token used in Python, Perl,
  C, etc.
  
  Note to self: There ought to be a way to transform such
  poor-man's dashes into en/em dashes, and quotation marks
  to "smart" quotation marks.

- Link transformation into HTML anchors tags is poor, or at
least too rigidly parsed.

  Problem: Some examples of links that do not work:
  
    The document (found "here":http://www.zope.org).
    
    <dtml-var "'This is a \x022link\x022:http://www.zope.org/'" 
      fmt="structured-text">, 
   
  I'd love to give cite other annoying cases I've come
  across, but I don't remember them. ;-)
   
  Solution: Tolerate parantheses, and accept that URLs that
  are terminated with end-of-line. Provide better syntax for
  specifying URLs, such as this:
  
    A product called Zope (http://www.zope.org) can be found
    on the _Zope site_ (http://www.zope.org).
    
  which would be transformed into:
  
    A product called <a href="http://www.zope.org">Zope</a>
    can be found on the <a href="http://www.zope.org">Zope
    site</a>.
  
- Structured text code should not wrap transformed text in
paragraph tags (<p></p>), or should at least make this
wrapping optional.

  Problem: I often display stx in places where a new
  paragraph creates unnecessary vertical padding that
  violates page design -- for this purpose I have been
  forced to write a simple External Method that removes the
  offending paragraph tags. IMHO, this ought to be
  unnecessary.

  Solution: Provide necessary option.
  
- Structured text code not available to DTML.

  Problem: The code is only available to External Methods
  and products. DTML can only get at stx through dtml-var's
  fmt attribute.
  
  Solution: It would be swell to have an _.stx() or
  StructuredText() construct.

Define "top-level namespace"?  This is one of my favorite things about
Python.  You get the behavior you want below *for free*, because modules
are done the Right Way (tm).

'-- spam.py ---
| FOO, BAR, BAZ = range(3)
| 
| class Spam:
| 	def __init__(self,foovar):
| 		self.var=foovar
`--
'-- eggs.py --
| import spam
| can=spam.Spam(spam.FOO)
`--

Alternatively, if eggs.py uses spam.py heavily, and is closely integrated
with it:

'-- eggs2.py --
| from spam import *
| can=Spam(FOO)
`--

I use both styles -- and you can choose!  Clean namespaces, or terse
syntax -- voluntary namespace pollution.  You can even be selective (and
this can really be fun) with expressions like:

'-- eggs3.py
| import spam
| FOO=spam.FOO
| Spam=spam.Spam
`--

if you're heavily using FOO, but not BAR or BAZ in eggs ...

For some strange reason, although they have come under lots of fire,
tuples make perfect sense to me.  They don't seem to confuse new
programmers much, either, since I've been introducing lots of people to
python...

For example; lists used as dictionary keys, if mutable, would have all
sorts of confusing effects.  Class instances, being explicitly references,
don't have this problem; but if you pass a list in as a dictionary key,
change the list... what should happen?

class A: pass
x=[]
q=[]
# you may want to think of that as
# q=copy(x)
# instead
y={}
z=()
a=A()
b=A()
y[a]='a'
y[b]='b'
y[z]='z'
# broken, but to prove the point
y[x]='x'
print y[q]

The same thing goes for strings... I dunno.  Type-defined mutability makes
a lot of sense to me.

Doesn't that just *look* nice?  This is certainly how I'd write this
happening in pseudocode, and I was overjoyed to find that python did it
automatically.

> is more immediately grokkable than
> 
> 	GetABC(A, B, C)   # assuming these are "out" parameters

This style is BAD BAD BAD.  I don't like having my variables manipulated
by functions, if they're mutable... but it would be even WORSE to have the
symbols actually changed!  Nonsense like this contributes to some of the
least readable code I've ever seen in C and C++ ... ugh.  I *wish* you
could return tuples in C++ =)

(The worst part about this is that SOMEtimes, calling a function would
create new variables for you, or reassign them, and sometimes it
wouldn't... ugh.  I don't like it.)

> Well. Sure it is. Damn, I think you're right. ;-)

Glad you see it that way =)

(Tuple unpacking is also brilliant, by the way, for constructs like
	for key,val in dict.items()
)

Subject: [Zope] efficient internal redirect
Message-ID: <38CCA329.9A3754CC@open.ac.uk>

I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

Not exactly. I suggest you read it again. What you and Martijn propose
gives _no_ type safety at run-time. That's just like using constants,
except they're wrapped in a module namespace.

And they do pollute the top-level -- that is, the module-global --
namespace. Let me know when you find out how to enumerate the values in
an enumerated type, and how to convert an enumerated value back to its
name -- and then I might think you're up to something.

Similarly to C++, Python classes behave like namespaces, so you can
avoid pollution by wrapping the values in a class:

	class Foo:
	  FOO, BAR, BAZ = range(3)

and so you can enumerate the values as attributes.

True. However, personally I prefer lexical scoping -- which I hear is
under consideration for Python 3000 -- to the weird three-level
namespace that Python provides. Having to import "global" variables
because the compiler optimizes assignments is way uncool.

I'm not contesting that dictionary keys should be immutable, but rather
that lists and tuples are nearly the same things (*nearly*, but not
quite) with the crucial difference that lists are mutable. Why? There's
no real design here. The only scientific answer to that question is
"Because."

Take a look at my Redirector product, which does this very thing -- it
lets you create Redirector folders which, when rendered, simply redirect
to somewhere else.

It uses regexps to let you apply patterns, such as saying that "/Parrot"
should redirect to "/PetShop" but than "/Parrot/Fish" should redirect to
"/Aquarium". It allows 1:1 redirects as well as many:1 redirects.

Dylan Jay has derived an improved version that supports simpler group
replacements using replace(). Both versions are on zope.org.

I agree with your points, but what is more important for me,
is that the rendered HTML is syntatically correct

* this is an item

* another item

* a third item

currently renders as :

<ul>
<li><p>this is an item</p>
<li><p>another item</p>
<li><p>a third item</p>
</ul>

which is not very slick.. I'd prefer a forward-compatible
list-rendering format, complying with HTML4.0 and XHTML,
looking like this :

<ul>
<li>this is an item</li>
<li>another item</li>
<li>a third item</li>
</ul>

Anybody who has tried to make Netscape4.x understand CSS
without properly closing tags will understand my point..

Thankyou for replying

Whilst this is I'm sure a useful mechanism redirecting
whole folders is overkill for what I need to do.  I have
many links into a tree and wish to have a very simple format
for the external links and an internal mapping mechanism
which maps each link to its real URL.  My question remains.
What's the most run-time-efficient (not development-time-efficient)
way of doing it?  I think you gave me the quickest development
route which is not quite what I was asking.

I agree with theese purposes on Structured Text...

I would like to be able to write simple tables with Structured Text.
Something like :

| FirstName | LastName | Age |
| Olivier | Deckmyn | 25 |
| Guido | Van Rossum | 32 |
| Linus | Torvald | 29 |

That will build a simple table :
<table>
  <tr>
    <td>FirstName</td><td>LastName</td><td>Age</td>
  </tr>
  <tr>
    <td>Olivier </td><td>Deckmyn</td><td>25</td>
  </tr>
  <tr>
    <td>Guido</td><td>Van Rossum</td><td>32</td>
  </tr>
  <tr>
    <td>Linus </td><td>Torvald </td><td>29</td>
  </tr>
</table>

Customization could be done with CSS...

Why can't they be the one and the same? Redirector is fast -- I suspect
the difference in speed between Redirector and something else would be
negigible.

Remember that a Redirector folder is in itself just an index (of
regexps -- it's not hard to wire the lookup so that, if the term is not
a regexp, then it will use a dictionary, which is a lot faster). It does
not need to contain anything, and you need only one Redirector folder to
accomplish what you ask for. Let's say you have three areas that others
link to: Downloads, Registration, and News. First, create a Redirector
folder called, say, /Targets. Then edit the folder's redirection
mappings to look like so:

	From                   To
	Downloads              /Downloads
	Registration           /Snark
      News                   /News

Notice that the Registration name maps to /Snark -- this to illustrate
the mappings have nothing to do with the *names*. Now, having done this,
you can access your mappings like so:

	http://www.myserver.com/Targets/Downloads

which will redirect to

	http://www.myserver.com/Downloads

Isn't this what you want?

Shouldn't that rather be

After all, we *are* talking about paragraphs here. I happen to like --

Subject: [Zope] getting port number into URL - was where port num gone
Message-ID: <38CCBEF7.BF8534E5@open.ac.uk>

I'm sorry to ask this again but there must be a way of
getting a port number into a url without being explicit
about the address.  There has to be because absolute_url()
does it inside a tree.  I just don't know what I can use
and the expression syntax to do so.

I have this

root
    ltscimages
        someimage
    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltscimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

.. not necessarily.. the <p>s imply a paragraph of text,
which is not necessarily what is contained in the <li>..

i agree that in most cases the visual result is better with
the <p>, but this should really be taken care of with css.
As far as possible, presentation and content should be
separated...

the <p>s would be ok with me, if we just got the <li>s to
close correctly, but i don't think they should be there if the
reason is purely aesthetic..

Imho closing the <li>s is all we need -- adding padding with CSS works
with the latest browsers, but we still have non-CSS browsers. As much as
I prefer pure, CSS-enriched HTML, it doesn't work all that well in "real
life". Not yet, anyway.

I confess, what you have is a very good idea.  The reason I'm hesitating
is because there won't be two or three areas and its wrong to call
them areas.  They will be single documents and a little bit further down
the
road there may be hundreds of them needed and not in any homogenous
flat structure but at different places in a tree.  Also,
I really do need every last inch of speed out of this part.

Hardwiring your code to use a dictionary looks like a good idea for
the present.

Some questions:

1. does your product redirect back to the client or within zope?

2. assuming it were hardwired as you suggest what would be the runtime
cost over just having folder methods in zope do the redirection?

3. I haven't touched python for 2 years now (though I did use it a lot
then) - I'm very rusty.  Could you supply a patch to hardwire in a
dictionary
instead of the regex code?  Assuming 2. is satis this *could* be a good
answer.

4. still looking for an answer to my orginal q - what's the most
efficient way?

One of myw own - words in single quotes 'like this' should NOT be turned
into code examples.  Most people do not write code examples in their texts.

Or add the whole special_formats dictionary available in PythonMethods to _.

In general, strucutred text needs a complete rewrite to make it extendable
and customizable.  Using the current structure you end up commenting stuff
out and rewriting sections of the code, which is not a very good way of
working.  But I doubt DC have the time for that.

Why not derive a specialized version of my product ("Redirector Method")
that descends from not Folder, but SimpleItem? If each such method
represents only a single "mapping", you get what you ask for.

Of course, if you have plugged your Zope into Apache, then it would be
more efficient to use mod_rewrite anyway.

> Some questions:
>
> 1. does your product redirect back to the client or within zope?

Yes. It forces an HTTP redirect. I don't if Zope is re-entrant; that is,
whether you can emulate symbolic links by passing the request, modified,
back into Zope.

> 2. assuming it were hardwired as you suggest what would be the runtime
> cost over just having folder methods in zope do the redirection?

Not sure if the word "hardwired" is correct here. After all, what I just
described to you in the previous email was not about changing the
product itself -- that's hardwiring -- but changing the parameters to
the product's *folder instance* -- that's Zope. ;-)

What I suggested about using a dict for non-regexp mappings does not
involve any hardwiring, either -- I meant patching the product to
support dicts *in addition* to the existing regexps. Basically in the
folder's management interface you'd simply specify whether a mapping
used a regexp or not.

Runtime cost: You would have to time it. Marginal, unless you're
expecting a gazillion hits.

Let me think about it. I'm pretty busy -- perhaps Dylan is up to the
task, he did the previous patch.

mod_rewrite.

You know, I have a similar problem... I have 6 aliased IP addresses. 
I'm running 3 zopes, at the moment.  All of them have been told what IP
address to use.  The first can listen to 8099 and 8021 no problem, but
the rest of them complain.

if I do -f '' and -m '' everything is fine, but they're all listening to
8080, so what's the gig?

netstat shows localhost:8099 and *:8021, and the same for the other
server that I set to 9023 and 9023 respectively.

Does Zserver listen indiscriminately on ftp and monitor?

But still people do change compilers! People have added garbage collecting
to the Python interpreter, list comprehensions, and there's the whole huge
stackless effort. I'm sure there are more examples in the past, for Python.
Without open source, this wouldn't have happened.

I've thought about it too, and no time either. Maybe we should get

That's indeed a shortcoming in Zope as it stands, but that's not an

That's true, but please note that C's enum is used successfully and 
isn't checked either.

I agree it might be nice to have a more elegant way to deal with
enumerated types. Perhaps as a result of static type checking extensions?

Well, it makes sense to disallow mutable dictionary keys. You asked why
have two kinds of lists, I tried to give the answer. Lists and tuples have
been moving towards each other in recent Python versions, though; I believe
originally only tuples supported unpacking. If there was somekind of
mutability system in place that could replace tuples.

It's cute though, as immutable objects behave like pass by value objects
do (except those darn tuples again, if they contain something mutable like
a list or an instance). I think that's a neat idea.

Python has a syntax for that:

You have misunderstood what I'm asking completely (probably my fault).
I am using apache and zope, some pages served via the zope-->apache
route, some
directly from Zserver (faster than going via apache) and some just with
apache. Some addresses are already being rewritten by apache - that's
not
a problem.  The mechanism I am seeking to use is just something like

<dtml-var destinationPage>.

Since this doesn't go back to the client between it has to be faster
than going back to the client and doing another request for these
particular
pages (which are in this database anyway).

Please can people reply to my original post without recommending
the redirector product.  I've reproduced the post below in the hope
someone can answer it for me.  Please don't reply telling me how
marvellous the redirector is - yes its a good idea but its not
what I'm looking for here - I'm just looking for some help to
know what's the fastest method and how to code it.

Original post
-------------
I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

> You have misunderstood what I'm asking completely (probably my fault).

If I were you, I'd definitely go over that original post of yours again
and consider how it can be rephrased -- because from what you say, this
is how I see your problem:

1) Pages within Zope
2) External sites or pages that link to these pages
3) You'd like the underlying pages to be separate from the URLs to which
these external pages refer, so that you can move the actual data around.
4) You want this to perform really well.

From this specification, it sounds like, aside from the marginal
performance loss incurred, you should be able to make do by using plain
old HTTP redirection. Did I get any part wrong?

You could use a kind of hub method like so:

<dtml-let Mappings="{
  'Downloads': PARENTS[-1].Downloads,
  'Foo': PARENTS[-1].Bar,
  'Snarf': PARENTS[-1].Smurf.Snark
}">
  <dtml-var "Mappings[REQUEST.Where]">
</dtml-let>

Assuming the method is called /Hub, then you can invoke it like so:

	http://www.andysserver.com/Hub?Where=Snarf

and it will display, in this case, the object "Snarf" in the root-level
"Smurf" container. While this works (you can also use a TinyTable
instead of a dictionary), this has a few gotchas, such as causing
trouble with proxy roles. No HTTP redirects, but not as elegant.

Oh, and did I mention how absolutely marvellous the Redirector product
is? ;-)

Message-ID: <3.0.1.32.20000313085541.0068c54c@bizux.net>

Can anyone give me any insight as to why the below URL doesn't work.

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?id=8185

After the URL is visited the manage screen comes up and tells me "No Items
were specified!" 

So I am a little confused as to why there is no item specified, when I am
sending the 'id' number with the URL, and will the activation of this
hyperlink take me to the manage screen or just delete the object and leave
the user at the page where the hyperlink was requested from.

Best regards, 

-M.

Yes.
Plain old inclusion (like #include in C) would work faster
because it doesn't go back to the client in the same sense
as HTTP redirection.

There is some way of doing this in dtml, I know because
I had something working at one point but I can't remember
what it is.  I do remember it only worked if the objects
that were redirected to (equivalent of included) were methods
not documents.


<dtml-var "whatever.whateverelse.object> gets the right object
but it doesn't get rendered.

This will imply some parameter to define whether you want headers or not
as not everybody uses them. Unless we can come up with some clever (but
visually pleasing in ASCII) format. 

Alexander also mentioned he does not like the <p> elements inside <li>
elements but IMO are required in cases where there are more than one
paragraphs in an <li> element. Unless we default single paragraphs in <li>
elements to non <p>, but then we break consistency.

I suppose a complete rewrite of stx is in order using a more modular
interface. For example I was thinking of one class per structure element
with the appropriate input method to receive the stx text, and a number of
output methods to produce a variety of formats, html,pdf,rtf etc. This is
the approach I followed in the Table patch but it is also slower. The
original stx was designed with performance in mind.

One suggestion I have (and it would be relatively easy to implement) is to
cache the rendered document in a volatile attribute attached to the
DTMLmethod/Document that contains it, together with a simple checksum of
the input text. Then we would be free from the performance constrain at
least to some extent.

Hi,

I have the following access rule:

<dtml-if "_.has_key('virtual_host') and REQUEST.environ['HTTP_HOST']==virtual_host">
 <dtml-call "REQUEST.setURL(path='/')">
</dtml-if>

The idea being that if a folder represents a virtual host (see the thread 'REQUEST vraible methods'
on this list for background...) you can just give that folder a virtual_host property which the
above rule checks for, and if it matches that in the header, if sets the base path to '/'.

However, if I try and access any folder with this rule in it, I get challenged for authentication
and get 'Authorization failed' no matter what username and password I use, including the root ones!

What is going on?

Would using re (so it can take advantage of multithreading) make up for a
more complicated rendering engine?

This wouldn't work in all cases - consider <dtml-var ZopeTime>, where the
output changes every time it's called.  If an object contains only
strucutred text then you store the rendered text too, and update it every
time the input text changes - the PTK has an object that does this.

manage_delObjects expects 'ids' - which is a list - as parameter. So,
try

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?ids=8185

or:

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?ids:list=8185

No, the user will be directed to the management screen. To prevent this,
you can either create a dtml method or you put something like:

<dtml-if delobject>
  <dtml-call "manage_delObjects(delobject)">
</dtml-if>

into the calling page and change the link to:

http://diis/inventory/outofstock/OOSStorage?delobject=8185

Hmm I hear the new re module of python1.6 is fast .. so a migration to re

If a block of structured text contains dynamic content then you are right,
caching won't work, but in many cases structured text documents contain
only static text. It does not harm to cache unless you have many stx docs
and little memory. I haven't checked PTK yet but in Zpdf Document the
rendered output is cached in a volatile attribute together with a fast
checksum on the input text. Works quite well and ZODB takes care of
garbage collection during object deactivation.

Hi,

I am new to Zope, and having some trouble.  I imported my directory
structure into zope, but zope doesn't recognize server side includes...for
example, 

<!--#set var="TITLE" value="Some title here"-->

I get the error: Unexpected tag, for tag ......

Is there a way to get zope to recognize server side includes?

Thanks,
Jessica

Referring to server side includes, I probably should have put that this
line was an error as well: 

<!--#include virtual="/include/header.html" -->

Subject: [Zope] mange_changeProperities external method
Message-ID: <3.0.1.32.20000313105947.0068de3c@bizux.net>

I have an a form in which the user can edit an instance of a ZClass and
resubmit the data. This data is to be used instead of the data that is
currently listed within the properties of said object.

After submitting the change I get this error:

Error Type: AttributeError
Error Value: 'string' object has no attribute '_properties'

The code that it is referring to is:

def editTaskProperty(self,REQUEST,RESPONSE):
  taskobject = self.taskstorage.REQUEST['task_id']

  for p in taskobject._properties:
    taskobject._setPropValue(p['task_title'], REQUEST['title'])

Can anyone give me any insight as to how the proper method of changing the
properties listed on an instance without the user catching any wind of the
management interface?

Best regards, 

Mark

You can do it in a DTML Method (very similar in an external method too)
like:

<dtml-call 
"MyZclassInstance.propertysheets.Mypropertysheet.manage_changeProperties(REQUEST)">

The reason I was using the external method was to avoid the user from
witnessing any use of the management interface.

This should work, is 'The Right Thing'.

If you are using a DTML Method, then it will be a method *of the
folder* containing the method. DTML method's dont add a namespace of
their own, so <dtml-var title_or_id> is supposed to give you the
folder's title.

No.

I mean that setting a production flag on the zope server and let all error
messages goes silent.

It will be very difficult and troublesome to keep track of all errors. Just
because some one have make a rename on one of my object, or the object is
being modify and thus not available.

Also, are there anyway to remove all the manage things from a production
site?

Are you killing the server between restarts, or closing it politely
with the management interface? The polite shutdown writes an index
file that speeds up the restart.

My development database has 30k objects, and restarts in under 3
seconds.

The call Pavlos gave does not visibly expose the user to the
management interface.  It does assume that the variables to be
changed were supplied in a form that caused this method to be
called, but that can be your own tailored form.  Or if you get
the values some other way, you should be able to pass them as
args to the call.

there are a few of howtos in Zope which use structure text were broken. I
dont remember all of them, but the one with date and sql is (I still can not
read it).

BTW, I  think structure text should be not be used in current way.  I think
a good use of structure text is to use it convert from/to. Instead of
publish.

A greate tool but in bad use.

But what would that look like?  The task requested by the user can't
be completed, so they need to get *some* sort of error message.  Or is
it that you are running with -D and so getting the python tracebacks
in the error web pages and you want to eliminate those?  In that
case, just remove the -D from your start script.

No, but anonymous users can't (by default) access the management
screens.  If your visitors have userids, just don't give them
permission to access the management interface, and they'll never
see it.

switching to standard ISO format (errr, I guess that's SISO), everything

If it's a DTML Method, you could do <dtml-var
"whatever.whateverelse.object(_.None, _)">

There is also a _.render method that I've never had occasion to use.

Also, if you want to make things a bit more generic and work somewhat like
the Redirector, you could also do a
<dtml-var "REQUEST.resolve_url(the_new_complete_url)(_.None, _)">

All untested, but will hopefully help you along...

Hi,

I have the following python Class in MyTest module:

import DocumentTemplate

class Test:
	index_html = DocumentTemplate.HTMLFile('test_form.dtml')
	
	def __init__(self):
		... 

	...

	def mymethod(self):
		return 'Hello'

In my DoTest.py module i have:
import MyTest
t=MyTest.Test()


If I run:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t

i get the correct output (a html file with http header).

but if I try:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t/mythod

i get the following error message:
***************************
Status: 404 Not Found

...

  <H2>Zope Error</H2>

I really don't know what is my mistake. I'm pretty sure that mymethod is a
method of the Test class. I can also access to the variable index_html of the
Test class, so why am I unable to access Test instance methods this way?

Actually, I also tried the example in the Zen HowTo: The (old) Product API
Tutorial. Is there now another way to call a python class instance method
with the debugger?

If I do the <image src=imagename explicitly I have to fill

Also, is there a general mechanism for doing this sort of thing?

of course, replaced the lib/python/ZODB/TimeStamp.c file.)

I hope so because I just did it and it seems to have solved
the problem in as much as new News Items in my PTK-generated
pages no longer all have dates of 29 Feb. (I guess there may
be more finely honed ways of just causing a selective
re-build ....)


I note, however, that those News Items that were created with wrong 
dates, still have wrong dates (at least as displayed on 
the Web pages). Perhaps this is a problem that is just
local to the PTK?

Yeah, I knew that, but I love the fact that everything in python is really
just assignment, so I do it explicitly a lot.  I got carried away... :-)

Your method does not have a doc string.  ZPublisher will not call a
method unless it has a doc string.

The FTP handler does not accept a hostname argument in it's
constructor.  This is probably an artifact of the medusa code. 
Shouldn't be a hard fix.

The monitor server is hardwired to localhost.  I believe this was a
security decision.  You can hack z2.py any way you like to remedy it.

Nope.  Zope does not speak SSI.  It speaks a very similarly looking
language called DTML.  DTMLs 'old' syntax _looks_ like SSI, but it is
not.  It is syntactically different in many cases, and does not support
neccesarily same kinds of tags.

I sugest you read the Document Template Markup Language Users Guide on
the zope site.  It's in the Documentation section.

Subject: [Zope] condional client-side code
Message-ID: <38CD3812.64591827@open.ac.uk>

Ideas please - how to do this.

I'm using zope in frames and need some output to be
condionally there depending on what the window name
is.  The idea is  for client-side code to decide 
whether or not its displaying in a frame and output
a header if needed.

The only way I know to do this is with javascript

"if (window.name=="whatever")" etc.
on the client side.  What makes is messy
is having to hand-process the stuff that's on the
"then" part to put it in document.write() calls.

This is quite messy because there's quotes and all sorts in
it.  It would be nice to write

    document.write("<dtml-var whatever>")

but because of messy chars and returns and so in
in the "whatever" document it doesn't work.  Also,
its really desirable to be able to have "whatever"
in just one place and use it in different ways in
different documents.

My current thinking is - "is there some way I could
process the contents on "whatever" on the fly so that
it would work with document.write?

Any other ways to do what I want?

I believe error code 11 is a segfault, pointing toward a memory
problem.  I just finished dealing with a situation where zserver
was restarting, and increasing the available memory for the
process circumvented the problem.  This may well not be your
problem, but it may be worth looking at.

Is Zope supposed to handle out-of-memory problems gracefully?

For images, you can use:

<dtml-var "imagename.tag(border='0')">

I'm not sure what a "general method" would apply to, but I'd hazard
to guess that any object that produces a tag when rendered should
probably have a similar tag method...

Does Zope leave a core file?  Try 'find -name core -print' from the top
level directory.

Subject: [Zope] Enhydra anyone?
Message-ID: <20000313201057.94590.qmail@hotmail.com>

Hi,

Is there any comparison between Enhydra (Java-based open-source
application server) and Zope (Python-base open-source application
server)?

I guess Zope and Enhydra are colliding head-on. :) Can anyone
give a little bit more background to Enhydra?

Zope site used to have a page about comparisons (like with
PHP), now I cannot find that page.

Having worked with Java (and previously with C++), I must say
that I don't have a positive opinion about Java. I know Enhydra
has this "open source" thingy and even tries its best at painting
"worldwide developer hall of fame" stuff, but it seems kind of
corny. I just don't think you can do open source well enough
with a language like Java which was designed by the corportate
and for the corporate.

It's not that Zope is excellent, it's not. But Python's CP4E
(computer programming for everyone) approach eventually will
make it longer lasting than anything else, (especially after
Python 2 comes out) and I just don't see how Java can
survive in the long run. As for Zope, I guess in the long
run it will need a major re-work, otherwise it will lost
the competitive edge.

Message-ID: <001b01bf8d2b$aaf24ee0$0201a8c0@iridium>

Here is my quick intro to Enydra and why I think it is interesting.

Enhydra (http://enhydra.org)
======

Licence : OpenSource.
Technologies : Java Servlets, XML DOM.

Java-based Enhydra has possibly the most interesting take. It uses
JavaServlets to provide content. You give it your HTML file, marked up with
some extra attribute tags :

<HEAD>
</HEAD>
<BODY>
  <P ID=Fred></P>  <!-- a Param tag with ID -->
  <P ID=Jim></P>     <!-- another -->
</BODY>

It then turns this HTML into a Java class with all the tagged elements given
getter/setter methods in the class. It compiles the class.

So now if I want to do something with the HTML fragment above I just create
an instance of MyClass and do things like :

  GetElementJim.SetText('My content for Para1');
  GetElementFred.SetText('My content for Para2');

In essence the Class models a XML DOM tree for the HTML put in so you can
now apply DOM methods to it to manipulate the model.

This neat because :

1. It's in compiled (well, as far as Java compiles) code so is quick.
2. DOMs  kick out "compressed" XML content, all redundant spaces CR/LF pairs
are removed.

Enyhdra also pools DB connections to improve performance.

Message-ID: <38cd5575.3a09.0@jps.net>

Hi Dave,

Unfortunately, I don't have an answer yet.  I am still trying to get the damn
thing to work.  I had ZMySQLDA working until I tried to run a query.  Then I
got the same error that I got when using MySQLdb.

Right now I am in the process of wiping everythin out (short of Linux itself)
and will try a re-install.  I hate doing this because I still don't understand
the source of the problem!

Anyway, I'll keep you updated...

Seems like this discussion should be moved to c.l.p., but ...

I don't understand your objection here. Tuples are immutable "by
design," or "by definition" if you prefer.

What alternative approach would you suggest?

We certainly benefit from having a mutable sequence type designed to
contain arbitrary objects.

We benefit from having a high level mapping type designed into the
language. You agree that dictionary keys must be immutable and you
appear to agree that sequences make useful keys, as well.

Under the covers, we also benefit from Python's design choice that
assignments create object references and the design choice that
dictionaries hash object references, not the objects themselves (which
therefore requires immutable keys).

So what's wrong with Guido setting things up this way and then saying,
"hmmm, this is pretty cool, we just need an immutable sequence type for
use in dictionary keys."

It's a little like the Old Testament Creation mythology. God creates the
heavens and the earth and he sees that it is good. But he decides he
needs to populate it. He finds that one human type isn't enough -- it
gets lonely. So it turns out that in His world, he needs two essentially
similar types, but with a key difference.

So Guido took a rib from the list and made the tuple.  ;)

For my own information, could you tell me how big big is?  I'm running a
database of 60K objects, and when there is a lot of activity on the 
database, the process grows to about 150M.  At around 180M, it
locked up and I had to restart Zope.  I think my server ran out of
available virtual memory.  (I'm moving the database to a dedicated
server Real Soon Now).

I use the attached script to batch-upload directories of jpegs as Photo

I found the source to String.__call__ (in DocumentTemplate/DT_String.py) very
enlightening. This is the same __call__ method that DTMLMethod and DTMLDocument
inherit.


    def __call__(self,client=None,mapping={},**kw):
        '''\
        Generate a document from a document template.

        The document will be generated by inserting values into the
        format string specified when the document template was
        created.  Values are inserted using standard python named
        string formats.

        The optional argument 'client' is used to specify a object
        containing values to be looked up.  Values will be looked up
        using getattr, so inheritence of values is supported.  Note
        that names beginning with '_' will not be looked up from the
        client.

        The optional argument, 'mapping' is used to specify a mapping
        object containing values to be inserted.

        Values to be inserted may also be specified using keyword
        arguments.

        Values will be inserted from one of several sources.  The
        sources, in the order in which they are consulted, are:

          o  Keyword arguments,

          o  The 'client' argument,

          o  The 'mapping' argument,

          o  The keyword arguments provided when the object was
             created, and

          o  The 'mapping' argument provided when the template was
             created.

        '''

You can see that __call__ with no arguments uses defaults of None and {} for
client and mapping, so essentially the template has nowhere to look up
attributes. This is why you must pass these explicitly. Apparently you can also
pass a mapping and keywords to the constructor but I don't think this is
possible from the management interface.

More ZZen is to be found in DocumentTemplate/DT_Util.py. This module contains
the expression evaluation machinery, as well as the code to the special
namespace variable, '_'.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A069@express.sematech.org>

I've put the following in a SQL method, but can't figure out where the count
ends up...

<dtml-in "_.string.split(tool_id)">

tool_id is a string (like 'EXP01 EXP02 EXP03').  For my normal DB activities I
use count-attribute name for the count total, but I can't seem to find out where
the count is stored in this example...  I tried getting the key with
sequence-key, which returned 1, but count-1 returns 0.

I've solved this already with
<dtml-if expr="_.len(_.string.split(tool_id)) > 1">

but this bothers me....  I know theres a better way!

Hmm, a simple test script seems to indicate that sending a child process
a signal 11 does not cause it to dump core.  Of course, it also does not
seem to cause it to return a status code of 11 either.  This might not
be a SIGSEGV, it might just be a coincidence that the return code of the
(crashed) child is 11.  (FYI, there are two processing going on here, a
'watcher' parent and a child, the parent prints the 'Aieee!' when the
child dies.

Does anyone out there know what a python program returning 11 means?

I think both NS and IE default to check for modified content 'only once per

I know that Zope has the capabality to keep up some sort of version
managament system for zope documents.  I have two questions concerning
this.  One, where might I find some more info concerning this.  And two,
what if I want to use my fav editor - say vi or pico...but that's another
war I don't want to start ;)...instead of the window that zope provides.
IF the file already exists in zope, and then I go and make changes in a
separate editor, and upload the file, since I am uploading the file, will
zope keep track of this as just another version of the same file?  Thanks.

The Very New Newbie to Zope,
Jessica

I don't know where the docs are, but I just started using versions
so I can answer this.

In your top level folder, go to the 'add' box and select 'version'
from the items to add.  This will create an object in that folder.
click on the object, and you'll get some management tabs.  You can
'join the version', and you can save or discard changes.  Once you
have joined the version any changes you make will not be visible
to anyone who has not also joined the version.  (Making changes
to an object will lock out any other updates to that object from anyone
not in the version).  When you are satisified that your changes
are working, you 'save' the version, which makes them visible to
the rest of the world. 

Each change you make to an object is committed to the zodb in a 
transaction, by the way, so even without versions you can
go back and "undo" a change you have made using the undo management
tab.  I'm not quite sure about the rules that determine when
a transaction is burried deeply enough in the undo stack that you
have to undo things above it to get to it, but it is still a
very handy feature.

Someone is developing a ZopeEdit program that helps with this.  I haven't
looked at it yet.

Yes, the upload should appear in the undo stack.

Message-ID: <00031317565600.03374@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

I'm trying to make my own pyhton classes and use them with zope, so I tried to
subclass the class Persistent. However, no matter what I try I get always an
error like:
***
Bobo-Exception-Value:
(<class exceptions.ImportError at 80a9d98>, 
'cannot import name Persistent')
***

I have read "The (old) Product API Tutorial", "Create a Boring Product in
Python" and "ZODB" HowTos but I didn't find the exact way to do it. Even
reading the Persistence module doesn't enlighten me too much: it's just the
license and a string.

So I would appreciate if someone could give a clue about how to subclass
Persistent and to which module it belong?

Oscar

If you're trying to import your product into the interpreter, you have to load
the Zope framework first. The Zope initialization is where the Persistent module
is populated.

From $zopedir/lib/python:

import Zope
import Products.MyProduct
etc...

Access Rules are triggered before authentication can be performed, so their
permissions are nil.  If you want them to access anything other than REQUEST
(as you do) you must give them a Proxy role.

A lot of this is actually a question of terminology.  It is true that
Zope keeps previous revisions of objects around.  This is how you can
'undo' them.  However, this is somewhat unrelated to a Zope 'Version'. 
In the case of multiple revisions of an object, we call them revisions,
not versions.

A 'Version' is an object that you can join or leave.  When you join it,
you are given a 'private view' of your entire managment session.  Any
changes you make will not be shown on the 'public view'.  You can leave
a version and rejoin it.  You can commit a version or discard it.  That
pretty much sums it up.

You do not need to use Versions to get the benefit of previous revisions
and undo, Zope does this for you out of the box.

Your question about editors is related to all this.  You can
edit/add/delete object through HTTP using the managment interface, you
can also use HTTP POST and GET methods directly, WebDAV, or XML-RPC. 
All of these methods are based on HTTP (some editors work directly with
HTTP, or use a protocol transported over HTTP like WebDAV).  You can
also use FTP.  Any changes you make with any of these protocols will
cause a new revision of an object to be written, meaning that they can
all be 'undone'.

FTP however does not work with Zope 'Versions'.  You cannot use FTP to
upload information in a Version that you have joined because FTP has no
join/leave/commit/discard semantics.

I have a method that takes a long time on a system that uses a level 2 DA,
therefore it blocks the entire site (it also uses UserDB so everything uses
the DB). How can I put sub-transactions in my DTML to give others a chance

Subject: [Zope] WorldPilot Performance
Message-ID: <38CD82B7.66FDB982@exceptionalminds.com>

Hi,

I've been playing with WorldPilot on my little notebook PC running
RH6.1, and have noticed that when I access my WorldPilot folder, my
processor spikes and stays spiked until I kill my ZServer and restart.

My machine is just only a 233 w/64Mb RAM, but I have never seen Zope
behave this way with any other products. Running a top shows that my
python/ZServer processes are consuming far  more than their fair share
of cycles.

Has anyone else noticed this?

Thanks.

zopistas,

how would I write a dtml_method to render a objects history (undoable
transactions/revisions)?  any insight is much appreciated.  how about being
able to export the objects history (revisions) via XML and then I could pack
and then reimport it into ZODB (or is this complete madness? ) - this way I
can still pack and keep revisions around of specific objects... 

i.e. I would like to keep all objects revisions but need to PACK the DB
(because its overwhelming large) -- what is the way, masters de zope?

many thanks,
george runyan		grunyan@emerging.com

Message-ID: <38CD88EC.36D70F86@ep.newtimes.com>

After looking at both Zope and Enhydra I concluded for my purposes that
they really fit into two very different realms.  Both tools
(applications, application interfaces, whatever you want to call them)
fit the bill for developing web applications.  Both tools provide for
HTML/XML markup to easily integrate with web designers. 

Enhydra deviates from here to be more consultant/development driven with
its class file delivery/deployment method.  Where as Zope continues, it
provides an interactive management model, where the web designer can
update an application and extent it without having to have development
support, there is no compile phase that needs to be done before
deployment.

I believe it depends on what your perspective; If you're more
development centric, Enhydra works great.  If you have to interface
developers and designers on a an ongoing basis and want to deligate more
control to designers Zope is the winner.

Well thats my 2 cents.

Message-ID: <m3ya7ms7uo.fsf@wacko.pdx.net>

I've been reading through code trying to figure out what is going on
here, where this message might be coming from.  My current train of
thought is that the 11 exit code being seen is in z2.py is a result of
sys.ZServerExitCode getting set somewhere and z2.py exiting with that
code.

So I've been trying to find where code sets sys.ZServerExitCode and
what I've found is in ZServer.HTTPResponse.ChannelPipe.close.  In this
routine, the value of self._shutdown is assigned to r which then gets
assigned to sys.ZServerExitCode.  

It looks like self._shutdown only gets assigned when
ZServer.HTTPResponse.ChannelPipe.finish gets called and a response
header contains an bobo-exception-type of exceptions.SystemExit.

So I'm guessing now that somewhere this exception is getting set but I
can't seem to figure out why.

Am I completely off base here?

Subject: [Zope] Problems with dtml-in batch variables.
Message-ID: <00031412082101.01516@localhost.localdomain>

Greetings,

I am using the ever-so-handy next-sequence-* and previous-sequence-* variables
for a batched list.  This all seems to work fine, allowing users to look
through bite-sized portions of the list.

However, there seems to be a problem.  Whatever calculates these values appears
to assume that the numbers are sequential, which, in my case, they are not.

So, whilst i get the correct number of items each time, they overlap when they
shouldn't, and the next/previous limits are reported incorrectly.

The dtml-in tag in question is :

    <dtml-in "sqlQueryHere()" size=4 start=qs orphan=0>

Any comments?

Chris,

Are you saying that realmedia and netperceptions do their stuff
using Zope?  I've scanned their pages and can't find evidence
of that.  Or are you saying to go with a non-zope approach?
Seems like the non-zope way might be more expensive, for
a small site.

I don't *think* there is canned solution to this in Zope, though
I haven't looked at any of the banner products yet.  But in
principle it is simple enough: the page that is responding to
the search query has access to all the search variables, so it
can decide which banner to include based on those keywords.  For
a simple banner list, dtml-if logic would be sufficient.  But
you probably really want it integrated with a complete banner
product.

In about two months I'm going to have to implement this for a
client.  I'm expecting to add it to one of the banner products
if they don't support it already by then <grin>.

I'm not sure what Chris meant, but it seems like you could do what Marc
wants pretty simply using ZCatalog. Just set up a catalog that indexes the
ads by keyword or title that matches the desired search. Then, when
presenting the search results, pick an appropriate ad from the Catalog...

No.  We just don't have a banner ad product that does targeting.

RealMedia does a very good job of targeting.  It's not (terribly) cheap,
but it does have lots of features.

NetPerceptions can help if you spend lots of time and $.  It's not a
banner ad system in itself, but a collaborative filtering engine that
you can produce recommendations with.  This can help in ad targeting. 
It's incredibly expensive.

And yes, I would say to go with a non-Zope approach right now unless
you're willing to put in the time to write an ad targeting and delivery
system yourself.  We'd love to see such a beast, but done properly its a
fairly complex and time-consuming undertaking.  We've chosen to
recommend off the shelf systems for a couple customers rather than
building our own so far.

Is there anyone else who has been having Zope crashes where SQL in related.  We

Subject: [Zope] User Role, Authentication, HTTP
Message-ID: <20000314035606.71539.qmail@hotmail.com>

Hi,

I have the following situation:

(1) I'd like to use Zope's security model, so I can prevent
    unauthorized users from accessing contents in subfolders.

(2) I want to keep user name and password in a database,
    not in acl_users folder. (Basically, I would like
    ZODB to be read-only. So I can't add users into acl_users,
    I have to add users into my own database.)

(3) I don't want to use the pop-up dialog box to enter the
    user name and password. I want to do it through HTTP
    form interface.

So, what can I do?

Is there a way in Python to tap into ZODB Authentication?
I mean, I could create a generic user for the purpose of
ZODB user authentication, and then activate the ZODB generic
user from the HTML authentication. Or is there a way to
add a role to the current AUTHENTICATED_USER, dynamically?
This problem seems common enough that people have probably
addressed it before.

Where can I find more information on manipulating Zope's
AUTHENTICATED_USER?

regards,

Hung Jung

Message-ID: <3.0.6.32.20000313212413.008ef100@pop.dnvr.uswest.net>

I have a few questions as to how to map zope objcts in python, and I'm
looking for help with this particular example.



I am trying to create a python method that will take one argument, a string
variable.  It will then find the people that match and return a list with
each of the person's data.



I have found two methods that come close to doing what I am after.  The
first one returns all of the people data, including all the variables, and
the second one filters out the people I don't want, but only returns the
ids.  I've tried switching aroung the map(None,self.ids) to
map(None,self.data) and I get typerrors from lambda.  

I don't fully understand how this is working or what the data looks like to
the interpreter, but I know I'm close

Can anyone help?



I've got ! these both work ! :

--------

    def peopleValues(self):
        """ return list of people's data  """
        return map(lambda x, p=self: x.__of__(p), self.data.map(self.ids))


    def remote_personlist(self, thisdjname):
        """ returns true with ids to remote people that match
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].meta_type == 'This Kind
of Person', rlist)
        rlist = filter(lambda x,p=self,s=thispersonname :
p.data[x].clientpersonname == s, rlist)
        return rlist

You're absolutely correct.  It doesn't appear to be in the documentation.  The
closest I could find was an offhand reference to 'sequence-length' in the ZQR. 
I just assumed that since 'previous-sequence-size' and 'next-sequence-size'
existed, sequence-size would also.

Did it, in fact, work?

Hmm... have you looked at the Generic User Folder Product?

I think it would solve your purpose. There is also a howto for

I don't think zope should crash if this happens -- but is there any time
when you'd be retrieving data that it wouldn't crash (insert name of your
favorite web browser here, it doesn't matter which one)?

Subject: [Zope] DTMLTemplate product 0.2.0 released
Message-ID: <200003140538.AAA03457@ml.media.mit.edu>

I've just released my first development version of DTMLTemplates.

You can find the distribution at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate

DTML Templates are documents that allow blocks of text to be named and
made available to other documents. The basic building block of
templates is the DTML "block" tag, which can also be used with other
DTML document types. Templates export their blocks. Another new tag,
the "suppress" tag, allows block definition without rendering.

Here are several nice features of blocks and templates that I believe
will greatly benefit the Zope community (several of these items have
come up recently in Zope email discussions):

	* defines libraries of methods in one file,

	* allows structured text formatting in a DTML document,

	* allows pieces of multiple documents to be combined,

	* allows complex web designs created with HTML editors 
          to be used as templates,

	* provides template elements that encourage proper
	  nesting of markup tags.

In short, I think that Templates offer great promise for the Zope
and Zope developers.

This release is a very early one, though.  A construct as fundamental
as this one may need both syntactic and structural tweaks to function
in the most useful way, and only with discussion can we figure that
way out.  Please don't count on this product being stable for at least
a couple of releases.  

I appreciate your interest and feedback.

This is a Zope crash, not a browser.  Zope dies with a NT exception.

I am currently adding this to my BannerClass foundation. I expect to
have this out in the next month or so. As to how well it will work, that
is up in the air at the moment.

<dtml-alert type=semi-vaporware>
"ZBanner System" (or whatever the final name will be) currently is
capable of hit/click tracking, verification of banner validity based
upon time (after, until, or during a date range), a set variable by
management, hitcount, and clickcount (I think that's all of them). It
also has preference capability (ad weighting).

It also supports ad style and type (where style is button, vertical
banner, and horizontal banner; and type is 'integrated', 'remote',
'local').  In the near future it will be able to call ads based upon
keywords passed to it.

So, why is this not yet fully available you ask? The feature I haven't
mentioned yet. Database independance. Basically, I want to get it set up
to where you can store your banners in the ZODB, and RDBMS, localfs,
whatever. So far, I have a good foundation, but need to pin down the API
better. WHen it comes out, I want to include an example implementation
or two. As soon as my test ZServer works properly again, I'll be able to
progress faster.
</dtml-alert>


And now we return you to your regularly scheduled thread ...

Wow, wow wow. :) Thank you very much. I'll try it out!
Seems exactly what I want.

It's funny, I have seen quite a few postings mentioning
about GUF and Generic User Folder before, (never understood
what it was, though,) and I even mentioned in my own message
that I wanted to create a "Generic User." But somehow I just
never made the connection. :)

# BEWARE OF THE LEOPARD!

# Set 'do_XXX' true to allow creation of XXXPythonMethods
# and ADD A MASSIVE GAPING SECURITY HOLE to Zope.
# DON'T DO THIS unless you use secure connections for ALL OF
# YOUR ADMINISTRATION or are RECKLESS and/or FEARLESS.
# Even if you DON'T create ANY XXXPythonMethods, just turning this
# on will PUT YOU AT RISK BIGTIME!

Of course, I then set
do_XXX=1   :)

I only ever run my Zope servers under a non-priviledged account.

Can anyone explain what sort of leopards I should look out for, as I 
can see that I'd want to use XXX-PythonMethods for a lot more things.

Tone
ps the icon for the XXX-PythonMethod object is way cool! :)

Subject: [Zope] httpd.conf HELP! please
Message-ID: <Pine.LNX.4.10.10003140058240.20645-100000@hal.rescomp.berkeley.edu>

Good evening. We are a student group here at University of California,
Berkeley, and for the past couple of months we have been trying
(unsuccessfully) to get Zope to work with Apache properly. (We are
Residential Computing, a group which provides connectivity and support to
the residence halls at the UC Berkeley.)

The situation is as follows:

Right now, apache has been configured to pass all requests to zope.cgi
except for our personal pages (/about/staff), which a rewrite rule is
directing to a static file system location.

Our problem lies in an internal section of our site. We call it
/internal/.

What we are having problems with is getting Apache to authenticate the
user BEFORE it redirects to /internal/ in Zope. The other snag: everything
under /internal/ is under SSL. One area where we are not certain is if the
require user authentication specs should be in LOCATION tags or DIRECTORY
tags.

In addition to advice, if you have a similar set-up we would really
appreciate a snap-shot of your httpd.conf.

I have included snippits of out httpd.conf file below.

Thanks for your help,
Sachin

I'm seeing that on a box running BSDI.  I haven't looked closely

I would like to open discussion on Version access over FTP. Few weeks
ago I have posted some suggestion on this to Jim Fulton, but no
reaction. I know he is very busy and so maybe here I get any
response. Below, plaese see copy of what I have posted to Jim.

Hi Jim,
I have a problem with versions with FTP. I already read your comment in
mail-list and also made little of traffic on the Zope and Zope-dev
mail-lists. After this, maybe I have a suggestion how to solve the
versioning also over FTP and not only HTTP. This problem arised for me,
when I tried to work with versions edditing my DTML code in Emacs.
        I suggest to be version object a container object. The access to
the version over FTP could be determined in URL. (The ID of version
object, to which I want to make changes, must be a part of
URL. Additioanaly, commands for join/leave, commit .. should be also in
URL, just after the ID version.) This mechanism could allow to work with
versions also over FTP. The classical version management over web
interface in collaboratin with cookies will not be changed, the
mechanism to work with versions also over FTP will be an addition. In
addition, in this way, the other people could see the version
('functionality of version') also over HTTP if they know the version ID
and put it in the URL.
        What do you think about this? If there is any other possibility
to solve my problem, could you inform me? 

Thanks in advance,



Could anybody response to this, please.

Evan,

Cheers, gave an anonymous proxy role, worked a treat :-)

I did notice while playing around with this that moving or copying DTML methods that have been set
as site access rules did have some bizarre effects I wasn't expecting. I think when I copied one, it
stopped working, or something like that...as well as some other such wierdities, is this to be
expected?

Chris

PS: What do you, or anyone else for that matter, think of the rule as a solution to the problem in
my earlier post? I don't *think* I need any magic folders or anything else, but I'd like to get a
second (third, fourth and possibly fifth ;-) opinion before I put it into production...

<dtml-if "_.has_key('virtual_host') and REQUEST.environ['HTTP_HOST']==virtual_host">
 <dtml-call "REQUEST.setURL(path='/')">
</dtml-if>

   I'd more interested in fixing fast reload problem. There were some
reports in the list, that after installing SiteAccess Zope sometimes hangs
for a few seconds when you press Reload (in browser) a few times. I can
confirm this behaviour, but I've never realized the problem is in
SiteAccess - I never ran Zope without SiteAccess :)

Hello,


there used to be a way to change the base classes for a ZClass. It's 
documented here:

<http://lists.zope.org/pipermail/zope-dev/1999-August/001288.html>

I haven't used it recently. It worked for me several time in Zope 2.1.1.

Make sure you backup your database before trying it.

Salut Olivier,


Did you solve your issue below? If not, please reexplain what you are 
trying to achieve.

If you want to render one of your ZClass with <dtml-var myClass> you may 
need to subclass "Renderable BaseClass" (available on the Zope site).

Or I am barking up the wrong tree?

Hmmm,

It would appear that a Site Root and a Site Access Rule containing the following are NOT the same:
<dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

as my site access rule didn't work :( (it left the URL, BASEx and absolute_url() unchanged)

The only way I could solve it was to do the following:

Site Access Rule:
<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

And then put an empty SiteRoot object in the folder of each virtually hosted site.

Why did I need to do this? (more out of curiosity than anything else...)
Also why do the SiteRoot objects have to be in the folder of the virtually hosted site? why can't I
just have one in the root folder which gets picked up through aquisition (they're all blank anyway
;-)

And, most importantly of all, why does adding a site access rule prevent FTP access to Zope?

Subject: [Zope] SiteAccess breaks FTP!
Message-ID: <38CE382B.E4088A9E@nipltd.com>

Hi,

I'm trying to sort out the relative URLs of some virtually hosted Zope sites.
In a nutshell, there some sites visible to the outside world as www.site1.com, www.site2.com, etc
These are in /site1, /site2, etc folders off Zope's root.
The redirection is done using Apache's Proxy method, but I need to sort out BASE, URL, and
absolute_url() type things, which I'm doing using the following Site Access Rule:

<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

and blank SiteRoot objects in /site1, /site2, etc.

The only problem is that since I did this, I get the following whenever I try to FTP into Zope
(which used to work fine and which we use quite heavily for content editing with Dreamweaver):

 550 Could not list directory.

Why do I get this? How do I stop it happening? (preferably without stopping using SiteAccess...)

If anyone has any experience with this, I'd appreciate the help...

Chris

Mourning...

I've been trying to compile DCOracle for 8i under Linux and
I'm _really_ not cut out for messing about with C libraries.
I know Anthony Baxter has done it, but I have a strange feeling
he's probably not near a computer right now.

Has anyone else got this working?
If so could you send me your Setup file? (Better yet would be
to get it added to the ones already in the DCOracle package.)

Thanks for your time,

Chris,


I had exactly the same problem as you.

I eventually found it was a bad idea to use the precompiled python version
shipped with the binary package. In fact when I do :

$ python
>>> import _mysql

it works. However, when I do :

$ $ZOPEHOME/bin/python
>>> import _mysql

It doesn't.


So, I think the best thing to do is to bypass the binary python shipped with
the tarball. I'm dowloading the source version to check if it is ok.

I can't get this to work at all:
<dtml-if "sequence-size > 1">
zope complains about not being able to find 'sequence'.  I had solved this issue
before with a let tag <dtml-let size=sequence-size>, but it seems very wasteful
and adds a lot of syntax overhead to the code.  How can I access the sequence
variable in an expression?

Actually, I'm checking to see if I've got multiple elements.  If I do, then I
use IN () in my DB query, else I put in =.  When I split the string, I don't
know if I have multiple items.

Access Rules are designated by name within their container; If you rename
them, copy them, or move them, the new/renamed method will not be a Rule
unless you designate it as one.

Looks good! This is similar to the solution that Digital Creations came up
with, and is better, I think, than my SiteRoot behavior.

> It would appear that a Site Root and a Site Access Rule containing the
following are NOT the same:
> <dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

Was this Rule living in the subfolder where the SiteRoot would have been?

(they're all blank anyway

Location determines the point at which the SiteRoot affects the URLs.  If
they did their internal 'setURL' in the root, all that would allow is
replacing the initial '/' with the path of your choice, when what you want
is to replace '/foo' (or whatever) with '/'.  A variant of the SiteRoot
scheme in which you could say "replace /foo with /" in the root would
require either rewriting the URLn/BASEn and absolute_url code to include the
replacement, or a hook after traversal completes which allowed the
replacement to be done before rendering the final object.  Either would
work.

> And, most importantly of all, why does adding a site access rule prevent
FTP access to Zope?

This is news to me! Prevents how?  What are the symptoms, and does it matter
what the Rule does?

So you've confirmed this behavior, and it goes away if you remove
SiteAccess?  Does it matter whether you're using an Access Rule or SiteRoot,
or is having the package installed enough to cause the problem?

[Sorry, I pressed the wrong key with my last message ; so here it is :]
Thanx Alex !

I've been fighting a little with the URL, but I got it  :)

For thoose who would have difficulties (like I've had!) here is the source
(should be zc.py) :

#!/dev/null
#
# (c) 1999 M.T.G. Handelsges.m.b.H.
#
# This module is only an experimental Extension module to play around with
ZClass internals.
#

import string

def fetchzclass(REQUEST,prefix=""):
    rg=REQUEST.get
    PARENTS=rg("PARENTS")
    product=rg(prefix+"product")
    zclass=rg(prefix+"zclass")
    app=PARENTS[-1]
    prod=getattr(app.Control_Panel.Products,product)
    zc=getattr(prod,zclass)
    return zc

def strbases(zc):
    r=[]
    for i in zc._zbases:
 r.append(str(i))
    return string.join(r,"\n")

def show(self,REQUEST):
    "This shows the bases of zclass in product."
    zc=fetchzclass(REQUEST)
    return strbases(zc)

def copybases(self,REQUEST):
    "this copies the bases from class srczclass in srcproduct to dstzclass
in dstproduct."
    src_class=fetchzclass(REQUEST,"src")
    dst_class=fetchzclass(REQUEST,"dst")
    dst_class._setBasesHoldOnToYourButts(src_class._zbases[1:])
    rg=REQUEST.get
    get_transaction().note("Copied baseclasses from %s[%s] to %s[%s]." %
      (rg("srcproduct"),rg("srczclass"),rg("dstproduct"),rg("dstzclass")))
    return strbases(dst_class)

Here is the doc (still from Andreas Kostyrka andreas@mtg.co.at):

Well, install the attached zc.py in your Externals directory. Add
external methods zc_copybases and zc_show (mapped to zc.py/copybases
and zc.py/show) somewhere in your ZOPE. For demonstration I assume
it's in your root folder, and your zope server is called
http://myzope/.

Well, then use your browser to visit the following URLs (this does
more or less exactly what the above python magic does):

http://myzope/zc_show?zclass=YourZClass&product=YourProduct
http://myzope/zc_show?zclass=TempZClass&product=YourProduct

   This shows you the baseclasses of the two Z classes.

http://myzope/zc_copybases?
srczclass=TempZClass&srcproduct=YourProduct&
dstzclass=YourZClass&dstproduct=YourProduct

   (This should be a one line URL.)
   This does the voodoo magic above. And completly without shutting down
your ZOPE, and
   it does even comment the transaction nicely. (Interesting question if it
is undoable.)

And yes, the attached file is twice unsupported ;)
1.) The voodoo is not supported by Digital Creations, so it may change
    at any time.
2.) The external module is not supported by MTG, as its voodoo coefficient
    is to high.

Hi Alex :)

Nice to see that there is at least ONE good guy that looks at my
contributions...

So : Yes and No...

I've seen the renderable ZClass...
but...this is not exactly what I want :

I have two (or more) rendering methods ...
Sometimes I call one or another, depending on the page I want to render it
in...

I wanted to write :
<dtml-var myClass.render_1>
or <dtml-var "myClass.render_1()">


but never works :(
The only thing I've found to be working is :
<dtml-with myClass>
  <dtml-var render_1>
</dtml-with>

pas glop...

Hi Evan :-)

So, it's okay to copy a Site Access Rule DTML method to another folder and then set as a Site Access
rule in that folder? I could have sworn when I tried it, the original stopped working too...
...but I was probbably wrong...

Nope... I was hoping just to have one Site Root Access rule that got aquired for each site. Is that
not possible? :S

Evan,

I don't think it matters what the rule does, it's just enough to have one set. It does, however,
matter where it is. I had to remove the site rule in the root folder so people could get on with
their work, but I left one in one of the virtually hosted sites.

FTP access now works fine except in the folder with the Access Rule in it. That said, that folder is
a Squishdot site and so I don't think it was accessible from FTP anyway...

Hope this information helps :-)

Hello

Q: Which Linux to install..

We are tilting to RedHat..

Welcome any comparisons, recommendations, or guides about this..
RedHat
SUSE
Caldera

-Is there a recent table or article which lists the pros and cons which
relate to Linux family & Zope?

-What are the statstics among Zope users ? 

-Does Digital Creations know?

-Does it matter and if so : why / whynot?

I do _not_ want to start Linux vs. Linux thread.. but it seems to me that a
useful public page should be on zope.org with links to the How-Tos  per
Linux for gotchas etc..

If you prefer reply to me off-list. 

Thanks in advance any help.

Hello,

I am new to Zope, so this might be a FAQ, but my seraches of the Zope
archives and website didn't come up with anything. I have created a Zope
application (phoebe.rider.edu:8080/Athena).
I am using a Z Class with Property Sheets to define the fields for each of
my entries. The entries are created using a form on my Zope site. My
question is, is there any document, instructions, how-to, etc., that can
tell me how to edit the entries once they are submitted?

Since python interprets "sequence-size" to be sequence minus size, you need
to do a namespace lookup to get at the value.

<dtml-if "_['sequence-size'] > 1">

will do the trick.

Corel is more of a desktop version, so I'd say not, while Debian has a Zope
package so it's very easy to install and upgrade.  But I personally use
Redhat (and will install Debian 2.2 when it's released.  And OpenBSD when I
get my CD...).  Truth is that it doesn't matter.  Especially if all you're
running is Zope.  If you're running Oracle or some other commercial software
you'd want a commercial distrib such RedHat or SuSE.

Not really.  Just use whatever you're comfortable with.

Nice to know the trick, though.  Now I just need to find where the sequence-size
is stored as....

This is almost a religous subject but here's my two cents

it depends on your experience and what you want to do.

i've run Zope on Suse6.3, redhat6.1 and mandrake7.0
the differences between redhat and mandrake for a server are pretty
minimal, basically the pentium tuning in mandrakes rpms which are
meaningless in the context of installing zope and python. so for the
purpose of this discussion i'll call them both redhat. 

for automating startup of zope:
i personally found suse6.3 rc scripts to be alot easier to figure out
they have skeleton in /etc/rc.d/ which you copy alter and symlink into
the /etc/rc.d/"runlevel" directories you want to start and stop zope in.

try man init.d (in Suse)

for playing around with experimental stuff:
i would def. have to say go with redhat. if you want to play with stuff
like ZopeStudio(interface into Mozilla). Suse6.3 comes with a lot of
stuff in RPMs on CDs but requires a bit more experience to get stuff
installed from source and most sites don't offer suse RPMs which
generally aren't compatible with redhat RPMs. Suse itself doesn't offer
updates on most of its RPMs unless they're bugfixes for major programs.

 
for locking the box down:
i would go with Suse6.3. a good sys admin could lock either down. it
really depends on your experience from a sysadmin level. suse6.3 has a
pretty nice hardening script that passes SAINT with flying colors.
Bastille Linux is basically a redhat hardening script but i haven't
played with it at all and it tends to lag slightly behind the latest
version of redhat. 

for a minimal install:
i would go with Redhat.

my choice: Suse, but thats my personal bias cause i think its a better
distro. 

as for the other distros: the only other one i would consider seriously
is Debian, cause it has a very nice package management system through
which keeping your system updated is easy.

in summary: i really don't think it makes a difference, just go with
what you know.

This is untested but it should do the trick:)

<dtml-if "_.int(sequence-size) > 1">

as to why this doesn't work 

> <dtml-if "_['sequence-size'] > 1">
>Error, exceptions.KeyError: sequence-size 

i'm on shaky ground but here i think that your trying to lookup
sequence-size in the namespace variable but the batch process variables
aren't really defined in the global namespace.

This gives a key error as well.  To summarize what I'm trying to do:

<dtml-in "_.string.split(string_with_1_or_more_words)">
  <dtml-if "we_have_>_1_items">
   we have <dtml-var what_is_this_var?> items
  <dtml-else>
   we have only 1 item
  </dtml-if>

I can do the > 1 check with <dtml-if "_.len(_.string.split(string)) > 1">, but
it seems I should be able to get to a count-nnn var inside.  Since I'm not using
a SQL statement, I don't know what the variable is named.  sequence-size give a
name error wherever I use it (from the test screen of a SQL query).  <dtml-var
sequence-key> returns the fist digit of the word.

So, the question is, in the statement:
<dtml-in "_.string.split('item_1 item_2 item_3')>
what will the count-nnn variable be named?

Howdy sports fans.  If the San Francisco traffic doesn't double cross
me, I'll be speaking at the Bay Area Linux User's Group meeting next
Tue, Mar 21.  The complication arises because I'm speaking down in San
Jose at SDWest from 5PM-6PM, then have to hurry back to hopefully make
the BALUG meeting.

Unfortunately I don't have a URL handy for time, location, etc., but
I'll try and post it when I'm back in the office.

The subject of the talk is, well, Zope, plus a Big Announcement.

I can't comment too much on your problem, your report, although
detailed, still did not show everything, for example, how is it failing?
Does Zope show public pages but never lets you authenticate?

One thing I noticed is that you want Apache to authenticate, then you
try and pass the Auth headers into Zope.  You can't have it both ways,
either Apache authenticates you (and you are quite crippled in this
sense, using the front end web server to do authentication is not
desireable at all, and limits what Zope can do to a great extend) or
Zope authenticates you.  Perhaps I am not completly understanding what
you want to do, but I think you might be tackling too many problems at
once and your conf file apears to be very complex.

First, take out all the Apache auth and SSL and all the other Rewrites
and complexity and just get Zope to work with Apache.  _Then_ add
something else, and get it to work, and so on.  Further, you may want to
consult the Apache docs and inspect the environment that Apache sets up
for PCGI along each step of this process; Apache, for instance, may not
set up all of the CGI 1.1 environment variables in a way that makes Zope
happy when you use SSL.  Or maybe Apache ixnays the Auth header after it
does Auth.  I couldn't tell you either way.

This could very well be a memory error.  It would be interesting to know
if the underlying libraries could handle a dataset this large, in this
case it would not be Zope but the libraries (I can think of no reason
why python couldn't handle a 40MB object, but I can immagine a poorly
written python extension not doing this right, the old ct_sybase module
is a perfect example).  You didn't specify what database you are using.

There is only one reason why I can think of, clicking on the Shutdown
button. 

A quick grep shows sys.exit being called in a few places however, most
specificly in xmllib and pyexpat.  None of these calls set a value of 11
though.

Are you using any XML?  XML-RPC calls?

> Am I completely off base here?

Perhaps, it's a good avenue to look down however.  What I suspect is
that something is happening (like a SIGSEGV) that is causing the OS to
send a signal to the process whose default action is to kill the
process, setting the error code to 11 for some as-yet mysterious reason
(11 has *got* to be the clue however, I refuse to believe that it is
arbitrary, note also that SIGSEGV is signal 11, coincidence?).  A good
exercise may be to run Zope in gdb and wait, when one of these events
happens use gdb to inspect what's going on.  I'm no gdb expert however,
but I was under the idea that it could tell you when signals arrive (or
perhaps stop the process on the arival of a signal...)

I wrote a test script that forked a parent and child just like Zope. 
When I sent the child a SIGSEGV it returned an error code of 332.  Maybe
my experiment is flawed.  

Have you enough time to look that deeply?

To be more specific, it blocks all other requests through that and other
level 2 DAs.  Non SQL related calls and level 3 DA calls will not get
blocked.

Yeah that kinda puts a damper on the whole site... but that's just
because every access is now an SQL related call.

This is not what ZODB sub-transactions do.  Even if you were using a
relational database that has a notion of sub-transactions (Oracle has
'nested transactions' for example) that would not stop the blocking (of
course if you were using Oracle you would be using a level 3 DA...).
ZODB sub-transactions allow changed objects to get flushed to a temp
filestorage so that you can accumulate more object changes then can fit
in virtual memory.  There is no mapping of sub-transaction semantics to
any of the DAs.  In fact, if I remember correctly using ZODB
sub-transactions with SQL methods is Not A Good Thing.  I don't remember
the exact details.

Solutions?  Execute a shorter query or upgrade to a concurrent DA.

Subject: [Zope] More Z SQL head bashing...
Message-ID: <38CE754B.3F7DA16E@nipltd.com>

Hi,

Well, further to my earlier SQL post, here's the code I'm trying to encapsulate, but it doesn't work
;-)
The problem is one of getting a unique, integer, id from MySQL to use as a primary key for an
INSERT. And no, an AUTO_INCREMENT column won't help here 'cos I need to know what the number is
before I do the insert (it generates a reference number, which is used as the primary key, and needs
to be given back to the person doing the submission...)

Anyway, here's the Z SQL Method Code which goes into a MySQL DB connection:

SELECT COUNT(*) as exist FROM sequences WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
<dtml-if "exist==0">
 INSERT INTO sequences SET sequence=<dtml-sqlvar name type=string>, n=0
</dtml-if>
<dtml-var sql_delimiter>
UPDATE sequences SET n=LAST_INSERT_ID(n+1) WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
SELECT LAST_INSERT_ID() as number

When I try to test the method, I get a NameError for exists, which I presume is coming from the
dtml-if. Any idea what I'm doing wrong or other ways of solving this problem?

cheers,

Chris

I had a similar problem I just puzzled through, though I'm pretty new and don't
know the right ways yet :-)

What I did was create another DSQl query (sql_newID) that queried for the new ID
(select max(ID+1) as newID from table) and another sql_exist( select count
*....)  then I used this result, but it had to be within a <dtml-in > tag...

<dtml-in sql_exist>
  <dtml-if "exist > 0">
    <dtml-in sql_newID>
     insert into table (ID, name) values (<dtml-var newID>, <dtml-sqlvar
name...>
    </dtml-in>
  </dtml-if>
</dtml-in>

This worked because I knew the sql_newID and sql_exist will only return a single
value, so the loop only iterates once.  I've never seen the  <dtml-var
sqldelimiter>, though, so I don't know what it does....

Maybe this will help.....

I'm pretty sure now that async_loop is not exiting in my child process
so I'm guessing it is some other type of abort.  I'll try the gdb
avenue.  I'm pretty handy with that, but I've never done much
debugging python or threaded apps so....

I also grepped around the code and looked over every 11, sys.exit and
SystemExit I could find.  This is a real pain.

It's from the ZSQL guide, it lets you put more than one SQL statement in a ZSQL method. 
What I don't understand is why the 'exist' variable stops existing... (maybe I should have called it
something else... ;-)

Time of day can certainly be done. Shouldn't be that difficult to test
by IP, domain and browser, thoigu I admit I hadn't thought of them.


Basically, when called, a banner tests's it's validity agfainst a set of
rules, and those banners that pass are put into a list. that list is
built using weight, and the weights could be modified at runtime based
upon things such as keywords or other tests.

I have a bunch of really bad Python code sitting around here that tries
to do same.  I can't even remember how it does it.

It's got no docs and isn't even a working Zope product.  I doubt it will
help much.  But I can send it to you if you'd like.

That should work fine.  The only weird detail here is that the *icon* of the
method probably won't update correctly unless/until you make it not a Rule
before copying/renaming/moving it.  That's because the icon change is a
kludge.

Access Rules are *NEVER* acquired.  If they were, you'd have to think about
what they might do in every single contained folder.

Subject: [Zope] getting object given path
Message-ID: <Pine.BSI.3.96.1000314132519.17585J-100000@twirl.bitdance.com>

I know I've seen reference to a function to get an object reference
given a URL path, but I can't seem to find it.  It doesn't help
that I've been up for more than 24 hours trying to get this code to
work.

I'm just trying to update a series of objects programatically.
I have a form working that submits the data for a Catalog
query to select the correct objects.  The dtml-in statement
is working fine as evidenced by just printing the meta_data
Id.  However...

If I do a <dtml-with getobject(data_record_id)>, the 'id' variable
has the value of the id of the folder above the one the Catalog is
in.  Doing a <dtml-var> on the getobject call shows me a
'folder instandce'.  None of the cataloged items are folders,
they are ZClass instances.  Earlier I ran through the whole catalog
using the dtml-with construct and a reindex_object call, and the
reindexing worked fine.  But now if I try to call 
propertysheets.info.manageChangeProperties() I get told that 'info'
does not exist, even though that is definately the name of the
propertysheet.

I'm desperate to get this working for the client.  getpath returns
the correct value, so I think if I can turn that path into an
object I can access the property sheets and get them updated.  But I
also want to know what is going wrong with my Catalog and/or
the getobject method thereof.  I'm not sure where to start looking....

I'm running under Site Access, and I'm guessing that is the source
of my problem, somehow.

I found this snippet of code for an echo and set, but my attempts at

Hi,

I am starting to look into GUF, but the documentation is
not very well done: it's a bit cryptic and disorganized,
and makes too much assumptions on what the user knows.

Where can I find more help/examples regarding GUF?

The How-To in http://www.zope.org/Members/hippy/GUF_SQL_crypt
is not too good, either. Arrghh... give me some more
hints and I'll prepare another How-To, OK? :)

OK, I browsed a little bit about GUF on the mailing list,
and it seems that there are quite a few disasters. Horrible
disasters. Sorry, but GUF seems a bit too inmature.

So, let me come back to the original question again, beside
straight GUF, is there any other way of tapping into Zope's
security model and using a generic user?

Hi Olivier,


This sounds like a namespace issue.

When using the Python quoted syntax I think you need to enclose the namespace:

Could you try this:

<dtml-var "myClass.render_1(_.None, _)">


Here are explainations straight from my Zope snippets:

Note you could also pass additional variables:

Subject: [Zope] What if you can use Zope on development server only?
Message-ID: <20000314203306.46566.qmail@hotmail.com>

     Has anyone used Zope in a scenario where you don't have control of the 
production server?  In other words, I'm in a non-profit organization that 
rents space from a web host.  That web host doesn't have Zope installed and 
has no plans to install it.  I *might* be able to put Zope on my own 
personal Linux server, which would really make that machine like a 
development server.  Does anyone have any experience utilizing Zope in a 
scenario where the development and production servers are separate and the 
production server doesn't have Zope on it?

     I'd like to use Zope because our web site has reached the point where I 
really can't manage it myself (Ok, it reached that point over a year ago, 
but I'm finally frustrated enough to do something about it :).  I'd really 
like to be able to give other people in my organization, especially many who 
aren't ultra web savvy tech-heads, the ability to author content so I'm no 
longer a bottleneck to the site expanding regularly.  Zope looks like the 
best open source option to do this with.  I also considered Cocoon 
(http://xml.apache.org/cocoon/), but I know and love Python and Zope looks 
like it's both more mature and more well-established for this type of 
application.

     I also want to add that I *am* considering changing our web hosting 
provider, but due to other organizational changes in the non-profit it will 
have to wait at least six months (it's lower on my priority list than 
finding a replacement for our office manager, for example :).  I guess I'm 
just curious if there's a way to use Zope in my current scenario, without 
having to change to a web hosting company that already has Zope installed.

     thanks for any help anyone can provide,
     Anthony

But fs/select.c(sys_select) (in the linux kernel) DOES return
ERESTARTNOHAND of do_select returns a negative value.  This is, of
course, not documented in the select man page...  come to think of it,
it looks like the linux kernel returns ERESTARTNOHAND instead of EINTER
because (quoting the source comments) "ERESTARTSYS [instead of EINTER]
breaks at lest the xview clock binary, so I'm trying ERESTARTNOHAND
which restart only when you want to" [block comments are mine].

Fishy.

Well, after more poking around and experimenting, I'm able to make an
strace look like what my crashing server does by following these
steps...

start Zope (z2.py)
wait till everybody starts
attach an strace to child z2
wait till strace output shows I'm in select
send child z2 a SEGV

strace output matches what I see in production
event.log matches what I see in production

Now that I've figured this out, I managed to get ulimit set up so that
I will get a core file the next time this happens.

Let's hang on till I see the core.

I'm also going to play with getting gdb to work nicely.  I'm not sure
why this is failing yet.

I originally tried running Zope at pair.com, where I didn't have root access
to the box. I *did* have the ability to run CGIs and telnet in, however. You
can get Zope running in such a scenario. And, if they're running Apache with
mod_rewrite, you can even make Zope serve up your site's root.

    One note though: many ISPs don't want you to run a long-lived process.
If that's their policy, then you'll run into trouble that way.

    As far as running separate development and production servers, I believe
you can get something going. I think someone made a Product that will mirror
your Zope database in separate files. You'll lose all of Zope's cool dynamic
ability, but you'll at least be able to take advantage of the content
management.

Subject: [Zope] Getting the path of an Object
Message-ID: <38CEB515.DB36129E@globalcrossing.com>

Hey all, hope this one is relatively easy...

Background:
1. I have a zope site with folders, subfolders (possible several levels
of subfolders) and objects in them.
2. I built a simple interface to allow a user (with the correct
permissions) to see the tree. 
3. In the UI, each item (folder, subfolder, object etc) has a check box.
Kinda like the Zope UI


The question:
A user checks an object (folder, subfolder, object etc), how do I get
the path to the object that is checked.

i.e.

FolderA
	SubFolderB
		SubFolderC
			index_html

Suppose the user checked index_html in subFolderC. 
How do I get the path (which would be
FolderA/SubFolderB/SubFolderC/index_html)

The test code I am using looks like this (it's in a DTML Method):

<dtml-var standard_html_header>
<FORM ACTION="WhichFilesToExport" METHOD="POST">
<dtml-tree branches=objectValues>
  <INPUT TYPE="CHECKBOX" NAME="ids:list" VALUE="<dtml-var PATH_INFO>" >
        <IMG SRC="<dtml-var SCRIPT_NAME>/<dtml-var icon>">
       <dtml-var id>
</dtml-tree>
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Submit" >
<dtml-var standard_html_footer>

Using PATH_INFO obviously wont work since it returns the PATH_INFO of
this method and not the PATH_INFO of the checked item.


Any thoughts????????????

Thanks,
DR

R. David,

I think you want 
<dtml-in "Catalog(mystuff=mystuff)">
<dtml-with "resolve_url(getpath(data_record_id_),REQUEST)">
<dtml-call "propertysheets.MyProperties.manage_changeProperties(
           blah=foo
           blahblah=bar
           )">
</dtml-with>
</dtml-in>

This will change the properties to whatever you want for the instances
found in the above Catalog search (mystuff=mystuff).

All my best,

     Kevin, thanks for the information!  I do have CGI and telnet ability 
with this host, but I'm surprised that's sufficient to run Zope with.  I 
thought Zope would require a tighter integration with the web server (e.g., 
a mod_zope or something that needs to be compiled in so that Zope can catch 
special Zope-intended requests), and that I'd need root to install it.

     Do I have a misunderstanding of how Zope relates to the web server?  Is 
simple CGI access really enough to install and run Zope?  I was basing my 
understanding on the architecture documentation at 
http://www.zope.org/ZopeArchitecture and 
http://classic.zope.org:8080/Information/Components.

>     One note though: many ISPs don't want you to run a long-lived process.

     Hmm... interesting.  I'll have to look into that; thanks for the heads 
up.

     Yep... that's the tradeoff I figured I would have to accept.  I was 
even thinking I'd have to possibly write my own mirroring script, but wanted 
to see if there was a better way first.  Do you remember anything else about 
that product which might help me do a web search for it better (e.g., it 
definitely used the word "mirror", used the word synchronize a lot, etc.).

     thanks,
     Anthony

Well, I can't give it python, that would defeat the purpose of the 
chrooted webspace.

It seems to me that Zope maynot lend itself to being frozen.

Has anyone out there frozen Zope and managed it to continue to work?

If you use PCGI, Zope will work in a standard CGI environment. PCGI
(Persistent CGI) keeps Zope itself around in memory so that it does not need
to be loaded with each hit. However, you do pay the "fork tax", because the
small PCGI program needs to run. I don't know a lot about fastcgi, but you
may even be able to do that without root and eliminate the fork tax.

OK.. Two points.

Firstly, my appology.  I mistakenly believed sequence-size existed, since it's
previous- and next- counterparts do.  However, sequence-length aparently does.
(there is a reference to it in the ZQR, and it's also in the source code.)


Secondly, your problem stems from the fact that sequence-length is not a valid
variable name in Python.  you must use

<dtml-if "_['sequence-size'] > 1">

Annoying, yes... but that's the way somebody chose to go.  I don't know why,
but it's there.  In fact, if anyone could give me a good reason why it is this
way, I would be most appreciative.

Subject: [Zope] GUF: Generic User Folder
Message-ID: <20000315001632.8621.qmail@hotmail.com>

OK, I know some of you are out there watching. :)

Here is what I found out you can do to use Zope's folder
security features using your own user info database, your
own login interface, and without using GUF (Generic User
Folder). It's kind of simple, so don't expect too much. :)
Hey, but at least it does not lock you up and send you
into a panic attack. :)

(1) Have your own login interface, and use some session
    management product or cookies to keep track of whether
    the user has been authenticated by you.

(2) Create additional user-defined roles at the root of
    your Zope project. (Click on the 'Security' tab of
    the root folder, and scroll to the bottom.) E.g:
    'teacher', 'student', 'parent', etc.

(3) Create an acl_users folder at the root of your Zope
    project. Inside the acl_users folder, add new generic
    users. E.g: 'GenericTeacher', 'GenericStudent',
    'GenericParent'. Assign non-trivial passwords to them,
    of course.

(4) In your standard_html_header or equivalent, you then
    check against your cookies or session data. If the
    user is a teacher, then call:

    <dtml-call "REQUEST.set('AUTHENTICATED_USER',
                acl_users.getUser('GenericTeacher'))">

Voila! Now you can use Zope's security settings to prevent
people from accessing given folders.

Message-ID: <DBEPIFAAMMDGMCBPNKJCIELOCIAA.dell7000@thot.net>

I don't know if this is do-able, but here goes.  I'd like to do something
like the following:

<dtml-var main_header>
<dtml-var "external site">
<dtml-var main_footer>

I know, this defeats the purpose of Zope to some degree, but in this case
I'd like to include an external site instead of employing frames.  Let's
say, for example, that I'd like to showcase a resource located on another
namespace.

I've tried:

<dtml-var "REQUEST.resolve_url(my_external_url)(_.None, _)">

but I get a namespace error for obvious reasons.  I realize that the
header's <body> tags would conflict with the external resources' and hence,
I'm not banking on anything.  I also looked at Redirector and found it to be
great for redirection within the same namespace, but I'm unsure on its
ability to redirect to external resources (or namespaces).

My dilemma is that I am using Zope to design a site and require Zope's
numerous features, but I need to include a CGI-rendered page within Zope
header and footers without using frames.  Ultimately, I intend to re-write
the CGI as a Zope object, but at present I'm at a loss.

Thanks in advance,

Mike

Subject: [Zope] WorldPilot IMAP folder filenames
Message-ID: <E12V23Q-0005Py-00@under.eng.cp.net>

I don't know if there are any standards here, but I'm moving a TWIG
installation to WorldPilotand am running into some IMAP folder
naming problems.

We have TWIG configured to look in ~<user>/imap/xyz for an IMAP
folder called "xyz".  This (per memory) is consistent with how I
recall other IMAP clients working outside of our use of "imap"
instead of the cannonical "Mail" (historical reasons).  Now, I can
edit WorldPilot's MailListRoot to be "imap", but the problem then is
that WorldPilot then looks for folders in ~<user>/imap.xyz (ie the
file "imap.xyz" versus the file "xyz" in the "imap" directory).

I'd thought the defacto standard was to use a directory and then
files underneath that.  No?  Is there a reason for WorldPilot taking
this tack?  It makes the migration less elegant (we can't let people
switch back and forth)..

why do I need a concept of a sub-transaction. Is there just something that I
can call that will commit all changes up until a certain point and then
begin the new transaction? I realize this will break the transaction model
to some extent but if the method is long and each iteration is indepedent
this seems a reasonable thing to do.

To do the work using a shorter query would mean breaking the method up into
chunks and then having to call it multiple times which is pretty ugly.

Tell me how to get a concurrent DA on NT without breaking the bank and I'll
do it.
So far I have:

- MS SQL server - Apparently sybaseDA will work but havn't been able to
compile it on NT. You need certain files from sybase I believe.

- SQLAnywhere - same problem as above.

- Oracle - too expensive.

- MySQL - No transactions.

- PostgresSQL - Got the NT binaries but can't get it working. Also can't
compile the postgresDA.

- ODBC - Not level 3.

As far as I can tell the above represents all the options I have open to me.

It's not immature, just unforgiving :-) GUF lets get down to the bare
bones of an authentication system. Unfortunately this tends to mean you 
have to build it all up from scratch. 

Sometime RSN I'll finish a the one I'm working on that uses postgresql
and I'll bundle that up as a package for people to use, or use as an
example. Not for a few weeks yet, though.

Look in the download section of www.zope.org for one. The first
question, though - what do you intend to authenticate out of? A
database? LDAP?

Think of it this way: under normal circumstances if someone hostile got full
access to your Zope management interface, through a bug or password sniffing
perhaps, your Data.fs would be toast.  That's what backups are for, of
course.  Put XXXPythonMethods in the picture and your entire Zope
installation, any filesystem areas writable by the Zope-process user, and
any services accessible to that user are subject to abuse.  Some of this can
also be handled by backups, but subtle subversion over a period long enough
to render backups worthless is a much greater possibility.

You might end up as a CPU server for arbitrary Python programs.  You might
not.  LOOK OUT, IT'S BEHIND Y..<glurk>

They had to have *something* positive going for them :-)

Message-ID: <000e01bf8e30$2c24b200$0100a8c0@pinol1.sfba.home.com>

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in
general?

Thanks

I have a problem with allowing clients to download files from a Zope folder.
The HTML tag is as follows:

 <P><AHREF="/some_folder/Download/AvsB">AvB</A></P>

With "AvB" being the Zope ID in the Download folder. 
There is an acl_users folder on the "some_folder" directory and the user
belongs to the correct group. All sub-folders obtain their permissions from
"some_folder".

When a client tries to save the file, the client gets the following message:
"Cannot copy. Cannot find the file specified."

Any ideas?

G'Day.

I need sending mail with multiple file attachement...
But really cool product MIMETools is not ready fully.

Quotation from MIMETools Readme:
"Currently, the MIMETools product's only function is to provide the
<!--#mime--> DTML tag."

When expected implementing of <!--#boundary--> tag?

Thanks,
Dima.

Perhaps not, but in my experience, Bete ZOPE products are much more stable than
most.

In the site I am currently developing I send of e-mails with attaches.  From a
quick grep of the MIMETools files, you can see the boundary tag already exists.

Here is a quick example:

<dtml-sendmail smtphost="192.168.1.211" mailto="curtis@umd.com.au"
mailfrom="zope@umd.com.au" subject="Attach">
<dtml-mime type=text/plain encode=7bit>
Here is some text.
<dtml-boundary type=text/plain disposition=attachment encode=7bit
name="file.txt">
This is in the attached file.
</dtml-mime>
</dtml-sendmail>

Message-ID: <v04220800b4f4ec979e3e@[134.76.23.157]>

Hello Zopistas out there!

I just stumbled about the threadsafety of different SQL-DAs. I'm 
coming from mod_perl + MySQL so it seemed a natural choice for me to 
also run Zope with MySQL in the background. I'm doing research (= low 
budget) in clinical psychology and have people fill in all kinds of 
questionnaires regularly which I have to store somewhere later. 
Looking at some past messages it seems to me that free and speedy 
MySQL is awfully bottlenecked by MySQLdb and financially-out-of-range 
Oracle rules. But how big is the difference? Does anybody know?

It also came to my mind that I might be missing an important feature 
of Zope: ZODB. For some reason (lack of marketing?) I just didn't 
realize that there is a database behind Zope that I could use to 
store my stuff. Last night I read some documentation but I have some 
questions left open:

Can I access ZODB via TCP/IP socket to retrieve data for statistical 
calculations?

What about performance?

REQUEST.resolve_url().  URL should be unurl-quoted.

getobject actually uses REQUEST.resolve_url and getpath, IIRC, so this may
not help.  But give it a try.

Hi Alex...
thx again !

so, half glop...

Strictly using what you gave me didn't work :(

But, after seeking a little, the following works :

<dtml-var "myClass.render_1(myClass,_)">

But I really don't like it ! Why doesn't Zope give "self" itself ? As normal
python methods do ?

Thanx all !

Normally I'd say try,

href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST['REQUEST_URI']">;weblint"
(the new Zope syntax is <dtml-XXX, but you can use <!--#var XXX--> if you want.

But that doesn't work as REQUEST_URI gives a KeyError.
This is weird because other REQUEST variables seem to work. Any deep 
voodoo Zopistas know why?

<dtml-in "REQUEST.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

Hint:
To see all the REQUEST variables tack on /REQUEST to any URL you have 
(only works with Zope < 2.1.4) or put this in a dtml document
<dtml-var REQUEST>

To just get the environment variables;
<dtml-in "REQUEST.environ.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

So your code should work if you do this;
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST.environ['REQUEST_URI']">;weblint"

(If this seems long winded, it's because I'm writing this as I figure 
it out! :)

Hint: Remember that anything inside "..." is a Python expression and 
Python, *not* Zope syntax applies.

>I found this snippet of code for an echo and set, but my attempts at

That should work fine.

<sigh>
Ok, I probably shouldn't use them then.
</sigh>

But (you knew there was going to be a but :). They are *so* useful.
E.g. I've got a XXXMethod that imports the following;
import os, sys, string, mimetypes, stat
import DocumentTemplate
from Acquisition import Implicit
from OFS.Image import File
from OFS.content_types import guess_content_type

setting do_XXX=0 gives me;

<!--
  Error type:  ImportError
  Error value: __import__ not found
  -->

Which is fair enough as the docs on the Zope site say import is 
controlled. Can you please be a bit more explicit and let me know 
*what* I can import? The Python code is a bit over my head...

<compromise>
Would you say that you could use a XXX PythonMethod to debug code 
that is going to become an External Method?
</compromise>

Thanks for the help Evan, it's much appreciated.

You might be able to do something with urllib.urlretrieve (in an 
external method) and feed that back into Zope

*vaguely tested*
def doit(self, your_url):
	import urllib
	fn, h = urllib.urlretrieve(your_url)
	if h:
		fp = open(fn, "rb")
		data = fp.read()
	return data

You'll get junk like <HTML> and </HTML> in it, but it's a start...

I could be talking out of a hole in the top of my head here, but here goes:

If you get Andy Dustmans' MySQLdb Module 
(http://www.zope.org/Members/adustman/MySQLdb). It's designed to be 
thread-safe. I've always taken that to mean that if a Zope request 
does a ZSQL query that uses this module, then if another ZSQL query 
comes along (in a different Zope thread) then it is *not* blocked 
until the first query is finished, but runs alongside the first query.

If I'm wrong on this I would *really* appreciate a correction here.

The Digital Creations people aren't overly keen on MySQL because it 
doesn't support transactions, which the Zope system uses extensively 
(I only use it for 'Undo'). For the sort of queries I have (many many 
SELECTs, few INSERTs, that isn't a major problem to me).

I'd reckon so. Look into XML-RPC as an example. Of course you can 
just construct URLs that obtain the data you need (eg have a folder 
with lots of properties of the form prop_n and get the values as 
http://server/path/to/folder/prop_125) and perhaps use something like 
urllib (Python library) to do some machinations at the client end).


>What about performance?

People seem to reckon ZODB is fast enough. I think it's Python 
limited (but again, I could be wrong here). That's possibly where the 
pystone benchmark comes in; check these out;

180MHz 603e (Linux) = 850 (my home Zope system)
300MHz UltraSparc (Solaris) = 2800 (our production machine! :(
266MHz G3 (MacOS) = 4600
500MHz PIII (SUSE Linux) = 5400
700MHz PIII (Win32) = 10150!! (this is really annoying, this box cost 
1100 quid - the same as the yearly maintenance on our Sun iron :(

I have no idea why those last two numbers are so disparate for the 
want of 200MHz. We'll be putting Linux onto the 700MHz box to see 
what happens there...

hi all,
managed to install pcgi2 and got it working.  however, i got errors in apache

i think this is the same error i got if i use fastcgi ( connection refused). 
if i use pcgi, i still got this error but at a much lesser rate.  can anything
be done?  which knob to turn?  which bolt to tighten?

anybody?  tks.

I struggled a little with this and I now have it working (in development 
anyway) using an SQL database (PostgreSQL) to hold details of users. It 
seems to me that if you need to store a 'profile' on your registered users 
then this is the way to go. You need to read the README that comes with the 
distribution and also read the SQL How-to you've listed below. This do not 
really explain how to use it once it is set up so I added a 'Tip' at
http://www.zope.org/Members/Lunus/lunus_01

I'm still learning but I haven't found any reason _not_ to use GUF yet.

if you mean  and <dtml-if "(OUTPUT == 'PROENG') and 'MATRIX'">

then it is equivalent to <dtml-if "OUTPUT='PROENG'">

if OTOH you mean  and <dtml-if "OUTPUT == ('PROENG' and 'MATRIX')">

it is same as <dtml-if "OUTPUT=='MATRIX'">


which one did you mean ?

If you are not planning of storing thousands of forms and have them
accessed by many users/per second then ZODB is really a good solution and
it is *easy* too use. For example (in the simplest case) you can design a
ZClass that contains all the required fields and a form for the clients to
fill. A method can instantiate the ZClass in a folder and add the
parameters provided by the customer and thats about it in terms of simple
storage. You can have a method that returns the data in some convenient
format as a text file which you can then input into your favorite stat
package. Or you can get fancier and build an xmlrpc method in your stat
package if it supports xmlrpc (ie if your stat package is a set of perl
programs) and get the data directly into your package, or get even fancier
and incorporate your statistical analysis routines inside your Zope
product, but I am getting carried away here :-) (and yes it is doable, it
has been done and if you decide to take this route I have some PCA
routines in python you might want)

zopistas,

during load testing i often see zope / zserver restart or exiting
silently even if the loads are rather moderate.

i'm doing my load testing with apache benchmark, concurrency level
around 10.

doing:

/tstfolder/test is

<dtml-in some_simple_oracle_select>
<dtml-var titel>
</dtml-in>
</dtml-in>


"some_simple_oracle_select" being a simple zsql method.

the system is zope 2.1.4 on a suse linux 6.1 

we're going into production soon and we will have to support medium

Subject: [Zope] more on DTML Templates
Message-ID: <200003151443.JAA14787@ml.media.mit.edu>

Here is an update on DTML Templates, and a more in depth explanation
of how they work.

** Update ** 

I've updated the DTMLTemplate product to allow commenting out block
definitions and importing blocks using keyword arguments to the
blocks() method.  The new version is 0.3.0

Find DTMLTemplate at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate


** More Information **

Yesterday, Jonothan Farr (jfarr@real.com) asked about the differences
between Templates and the var tag.  Here's a short summary.


The Template product consists of the "dtml-block" tag and the 
"DTML Template" document type.  In a normal document, the dtml-block
described below::

   <dtml-block myblock>
     Block contents      
   </dtml-block>                   
                                 
works exactly like the following dtml::
                              
   <dtml-if myblock>
     <dtml-var myblock>
   <dtml-else>
     Block contents
   </dtml-if>

In addition, blocks can be used to insert structured text directly into
a DTML document (see the documentation for details)::

   <dtml-block mytext fmt="structured-text">
    * this is

    * structured text!
   </dtml-block>



DTML Templates use blocks in an additional way: to define DTML Methods
that other objects can use.  If the Template 'templ' contains the
following lines::

   <dtml-block myblock>
    Block contents
   </dtml-block>

   <dtml-block anotherblock>
    Another Block
   </dtml-block>
   Other, extraneous text.


then 'templ' will have two block methods that other documents can
access in this way::

   <dtml-var "templ.myblock">              ->  "Block contents"
   <dtml-var "templ.anotherblock">         ->  "Another Block"
   
Any document can also import all of the blocks of a Template into a
local namespace::

   <dtml-with "templ.blocks()">
    <dtml-var myblock>
    <dtml-var anotherblock>
   </dtml-with>

You can also refine blocks using Templates::

   <dtml-block myblock>
    <dtml-var "templ.myblock">
    with more stuff added
   </dtml-block>

   <dtml-var templ>

yields::

   Block contents
   with more stuff added
   Another block


** How is this stuff useful? **

I created Templates because I couldn't design complex and attractive
web pages for Zope using Dreamweaver.  I was always pulling out little
chunks of HTML and putting them into individual methods.  These chunks
weren't valid HTML documents, so I couldn't edit them individually.
With Templates, I create one document with all the HTML code I need,
and block out regions of the HTML using dtml-block.  I upload the
templates (once!) to Zope, and instantly I've changed the definitions
of all the template's block methods.  If I need to make further
changes, I can do it quickly in Dreamweaver.

Templates really makes coherent web design with Zope workable.

Hope this extra explanation helps.

Don't let me discourage you too much.  If you can isolate your Zope, you're
pretty safe.  That means a private or development installation only.  If you
are the only person allowed to touch the management interface, and you
really bite the bullet and do all of your administration through SSL, you
*might* be safe in production.

Right now, they are controlled into oblivion; I have vague plans to allow
some sort of safe import, but no clear idea what would truly be safe other
than trivial "you can use import as another way to spell x = self.foo"
stuff.

That should work well.  XXXPythonMethods and External Methods have very
similar semantics.

I wouldn't recommend it; Changes in the implementation of the authentication
machinery will break this, probably in the next release.  Even if that
weren't true, this trick would be discouraged.  This sort of thing is
*really* best done at the Python level, in a Product.

Subject: [Zope] questions about zope, netscape web server and certificates
Message-ID: <H0001bac07822848@MHS>

Hello all!

I have been posting questions every couple of months concerning digital
certificates and different types of authorization capabilities.  I think I have
finally convinced some people to look at using zope here at work.

Does anyone have any tips or hints for using Zope with Netscape web server on
HP-UX 10.2?  I don't have any way to test this before I get started, and I need
to have my ducks in a row before I start telling someone else how to make Zope
work (I don't have access to the machine that will host Zope).

I have used Zope on WinNT to display data from an Access database, and I have
played around with Zope on Linux (I did not have time to recreate my Access
database on Linux).

One of the things that I am trying to accomplish besides just trying to get
people to use Zope for more general stuff:

1. I need to allow users to login to Zope to approve requests for items (I am
looking at using LoginManager, Wizards and ZopePTK)
2. I need to use digital certificates for authentication (Verisign has a module
for Netscape web server which allows for certificate lookups to verify that the
certifcate is valid and issued by us)
3. I need to pass through the user information from Netscape so that I can keep
track of the user who is approving a request.
4. requests and approvals/denials will probably be stored in a rdbms, but some
information may need to be stored in zodb for searches

Message-ID: <00031510231600.01040@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi everybody,

I'm struggling with some concepts in Zope. The last one is the
DocumentTemplate.HTMLFIle behavior. I was trying to run the Zen 'The (old)
Product API Tutorial' examples when I came accross with this line of code that
looked strange for me (maybe I don't know python enough):

index_html = DocumentTemplate.HTMLFile('poll2.dtml')
...
p = Poll("What's for breakfast?", ['spam', 'eggs', 'toast'])
print p.index_html(p)
------------------^^^

It worked fine and rendered my form.
But what looked strange to me was to give p as an argument. So I tried
p.index_html: it gave me the dtml file (with &lt; for < and so on).

So fine depending on whether or not you provide an argument the rendering is
different. I tried to read the sources to understand better that behavior.

I read somethings about passing mapping object or keywords arguments. But the
question is:
As p.index_html is a DocumentTemplate.HTMLFile instance why can we
provide it with arguments like if it were a method or if we were instantiating a
class?

Hooray! My First Product.

http://www.zope.org/Members/shalabh/iTrack/

iTrack is an Issue Tracking System. It allows a team of people to keep track of
various issues about a project (or anything else under the Sun worth tracking
issues about, for that matter).

Currently this is in development stage (Version 0.2.0) but usable, as long as
you follow the instructions.

Basic Idea:
 o  Issues
 o  FollowUps
 o  Properties of an Issue
     - Title
     - Description
     - Type   (WorkItem, CodeIssue)
     - AssignedTo   (multiple selection of users)
     - Status    (open, closed)
     - (some others not listed)
 o  Types and States configurable through web

For more information:

Subject: [Zope] Symbolic Links in ZODB
Message-ID: <E12VGUF-0000l3-00@home.delysid.org>

Hi.

Is there a proposed way how to realize symbolic links in Zope.
I mean, how to place one instance of an object into more than one folder?

This is quite important to information organisation IMHO.

CYa,

Message-ID: <025401bf8e73$520ed430$a602a8c0@intranet.pspl.co.in>

Hooray! My First Product.

http://www.zope.org/Members/shalabh/iTrack/

iTrack is an Issue Tracking System. It allows a team of people to keep track of
various issues about a project (or anything else under the Sun worth traking
issues about, for that matter).

Currently this is in development stage (Version 0.2.0) but usable, as long as
you follow the instructions.

Basic Idea:
 o  Issues
 o  FollowUps
 o  Properties of an Issue
     - Title
     - Description
     - Type   (WorkItem, CodeIssue)
     - AssignedTo   (multiple selection of users)
     - Status    (open, closed)
     - (some others not listed)
 o  Types and States configurable through web

For more information:
http://www.zope.org/Members/shalabh/iTrack/Readme

If you use this, I'd be glad to know.

Enjoy!
Shalabh

Message-ID: <m3k8j4xj0e.fsf@wacko.pdx.net>

With my Zope server crashing about 6 times a day, how can I get the
durned thing to generate a core file?

I have this in my start script:

#! /bin/bash
reldir=`dirname $0`
PYTHONHOME=`cd $reldir; pwd`
export PYTHONHOME
STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE
ulimit -c unlimited
ulimit -a
/usr/bin/python \
     $PYTHONHOME/z2.py \
     "$@"

Which produces this on startup:
core file size (blocks)  unlimited
data seg size (kbytes)   unlimited
file size (blocks)       unlimited
max memory size (kbytes) unlimited
stack size (kbytes)      8192
cpu time (seconds)       unlimited
max user processes       2048
pipe size (512 bytes)    8
open files               1024
virtual memory (kbytes)  2105343

But when I crash with an Aiieeeee error 11, I get no core file.

Box is Redhat 6.1 2.2.12-20.  

I'm able to generate core files from some trashy c code just fine.

Subject: [Zope] newbie - create and call methods ?
Message-ID: <38CFC78F.30634CD9@inpg.fr>

Hello all,

I've been looking in the available zope documentation, listening to
this list, looking in the archive of this list (BTW : are you planning
to add a keyword search ?)... That is to say that I'm used to
searching for the info about open source OS and applications, but I
have to admit I'am almost discouraged using Zope as the doc is really
scarse compared with what is usually found. 

So, sorry, I post my newbie questions :

I would like to create a method to generate a link (href) with a
leading image and text formatting, and so on. I'd like the method to
have two arguments : the name of the link and the URL.

How do I create a method with arguments ?
How do I call a methods with arguments ?
Do I mistake attributes (for docs but not for methods) and arguments ?

If you have pointers to documents I haven't found that...


Thanks in advance,
Greetings,
Eric


PS: Here is what I tryed:
--- DTML method "meth_link"
<h2>
  <dtml-var img_puce_paragraph>
  <a href= "<dtml-var link_url>">
  <dtml-var link_name>
  </a>
</h2>

--- in an other method
<dtml-var name="meth_link" link_name="foo" link_url="la_url">

--- Zope error
Invalid attribute name, "link_name", for tag <dtml-var
name="meth_link" link_name="foo" link_url="la_url">, on line 6 of
txt_user_content

Subject: [Zope] acl_users and differing behaviour with Netscape/IE
Message-ID: <JLEIIKFACBHJPOBKDLODGEEBCAAA.alexander@limi.net>

Hi.

In our development, we stumbled over some behaviour that caused us quite a
headache for a while. We managed to find a less than elegant solution, but
it works for now.

The case is this:

We have the following structure (greatly simplified :)

 rootfolder
  |
  |-images
  |
  |-artists
  |  |
  |  |-acl_users
  |  |
  |  |-Artist1
  |  |-Artist2
  |  |-...etc


As you can see, we have separated the "acl_users"-folder belonging to each
of our artists into the "artists"-hierarchy. All images we use are located
in "images", under the root folder.

The problem appeared when we used DTML similar to the following inside the
artists-folder:

<dtml-with images>
  <dtml-var picture>
</dtml-with>

In IE, this would work just fine, Zope got the "picture" object from the
"images" folder and displayed it - no problem. But with Netscape and
Mozilla, we got authentication problems. It seemed as though Netscape
insists on sending the authentication request no matter what, and is
actually denied access to material that can be read by anybody (ie: the
objects in our "images" folder).

As far as we can see, this is a result of us having an extra "acl_users"
folder in the "artists" folder. Thus the logged in artist is not a user in
the root hierarchy, but only from "artists" and further into the tree.

We've solved this problem temporarily by putting duplicates of the images in
the "artists" folder.

My questions are thus:

1. Should we move the "acl_users" folder to our root folder? If possible, we
would prefer separating the artist users into their own folder, to avoid
clutter. But they should be able to access the rest of the site, like any
anonymous user.

2. Is this a problem with the way Zope authenticates users? Shouldn't users
that don't authenticate correctly at least have access to the content
readable by anonymous users? Or have I done something terribly wrong? :)

You see, we plan on having a "listeners" folder too, where we are going to
store individual listeners' preferences (what artists they want to be
notified of, what music categories they prefer, etc) - and I assume we will
run into the same problems here - users being authenticated only in the
"listeners" folder and below. They should be able to browse the normal web,
however, and add artists to their notify-list. Does this acl_users have to
be in the root user folder too?

Please CC me, as I don't have access to the list at the moment.

Regards,


Alexander Limi.

In the beginning, there was DTML.  DTML did not have expressions as was
designed to look very much like HTML, so names like sequence-item were
chosen.  Later on, expressions were added.  Names like 'sequence-item'
were obviously not going to do, because in a python expression it looks
like a subtraction.  So, the DTML namespace was given the name _, and
given a mapping interface which allowed you to look up names in the
namespace.  Thus was born _['sequence-item'].  _ is a mapping like any
other.

It's really not that bad, just kinda ugly.

WorldPilot properly displays the mail in my "Inbox" which is located at
"/var/spool/mail/sbaird" on the server. I can create new mail foldersrs
from within Worldpilot, but I can't access them from WorldPilot (I can
from other IMAP clients). The mail folders created are placed in
"/home/sbaird/" as "INBOX.personal" etc. I suspect this is just a
directory mapping issue but after reading everything I can I can't
figure it out. Any help would be appreciated.

The Python DB API spec 2.0 talks about different levels of thread 
safety. MySQLdb has threadsafety level 1 (= threads my share the 
module but not connections), the ORACLE db has threadsafety level 3 
(= threads may share the module, connections and cursors). I wonder 
what that means in % performance gain in high traffic situations. I 
have no idea where the different levels of threadsafety kick in. Any 
experienced users?

I was rather thinking of connecting directly to ZODB (in a kind of 
server mode) via TCP/IP - not via Zope. But I guess that's an 
aberrant thought that would rather be applicable to connecting to 
ZEO. Still I feel like I'm only beginning to understand but in about 
two weeks the new production site must be ready running zope ;)

Actually I'm not planning anything except to be prepared. I'm only 
starting and have no idea what I will end up with. So of course I am 
looking for a scalable solution. From what I've learned from the list 
scalability seems to be a weak spot of Zope (while e.g. the latest 
Enhydra includes a failover solution). I have no idea how much ZEO 
costs. (People from DC could you help here? I couldn't find a price 
on the website.)

I tried to understand ZClasses and read the documentation a couple of 
times but it didn't help a lot. So now I'm using Python classes which 
is very easy (maybe only because it's better documented). Can you 
e.g. simply add a dictionary or a list of dictionaries to a ZClass 
and access each element individually?

Would be nice if I could get back to you some time later to talk 
about the PCA. :)

Subject: [Zope] Need help with site structure
Message-ID: <NDBBKGBPJMFODAAFNMKEGECMCAAA.mduvall_22030@yahoo.com>

I'm setting up a Zope site, and would like to know if the approach described
below makes sense. I imagine this is a no-brainer for the more experienced,
but I'd appreciate some feedback so I don't go too far afield. Thank you!

In a nutshell, the site will give customers the ability to run reports
against application data that we're hosting for them. There will also be an
area for developers to log on and tweak parameters of the hosted app.

User Management
---------------
To keep the user accounts organized, I'd like each customer organization
(say, ABC Corporation) to have a folder that contains an acl_users folder.
I'd merely prefer to look at a few users at a time instead of seeing them
all together.

When a users logs on, I'd like that user to have a role of custUser,
custAdmin, or custDeveloper. I'd define these roles at the root. I'd also
like the user to acquire (if that's the term) properties of the customer
account, such as customer ID, so customer ID would be a property of the
customer folder(?).

So folder-wise there'd be;
root/customers (containing...)
root/customers/abc_corp
              /...
root/customers/xyz_corp (each with an acl_users folder)

Site Content
------------
This side of the site seems straightforward. The user's role will determine
what's visible/accessible, and the user's acquired customer ID will
determine which application data can be included in reports.

root/mysite (will contain content sub-folders, such as...)
root/mysite/eggs
           /spam
           /reports
           /developers (custDeveloper role required for access)
           (more content sub-folders)

So the question is...
---------------------
My main question is the user authorization / acquisition piece. How do I run
username and password through the contents of the root/customers folder?

If the folder layout described above makes sense, is this authorization
piece a job for a ZSQL Method, for GUF, or for both? Last week's "virtual
folders / url's" thread provided interesting info ZSQL Methods.

Also, any comments about holes or vulnerabilities in this approach are
welcome.

Thank you.

Mitch Duvall

Subject: [Zope] Zclass subclassing Image - how to manage uploads?
Message-ID: <38CFD0D8.B5391DC8@funcom.com>

I've seen numerous postings about this, but so far I have been
unsuccessful in successfully subclassing the Image with my own ZClass
(called VProduct for this case). Here's what I have managed to do:

* Create my new VProduct ZClass with Image as a base class
* Add a couple of new simple (string) properties to VProduct
* Modify the VProduct_add and VProduct_addForm methods so that my new
properties gets asked for and filled in (and using the system clock to
generate  unique id's)

This seem to work great, and I can move about in the Zope filesystem and
add instances of my VProduct class as I want to.

I have not been able to successfully integrate the file upload feature.
What I have done is:

* Add an input file <input type=file name=file> in the addForm method
* Putting a file name in this field and pressing submit button

From here I am not quite sure what to do with the image, but from
browsing earlier postings about this, it seems to have something to do
with calling manage_upload one way or the other.

In the VProduct_add method, I have the following special code:

<dtml-call "REQUEST.set('ts', ZopeTime ())">
<dtml-call "REQUEST.set('id', _.str(_.int('ts')))">

The above code generates a unique id for my VProduct instances, and this
works fine.

Inside the automatically generated:

<dtml-with "VProduct.createInObjectManager(REQUEST['id'], REQUEST)">

further down in the VProduct_add method I have the following stuff:

  <dtml-call "propertysheets.Basic.mange_editProperties (REQUEST)">

that code should take care of modifying the properties of my VProduct
instance (and assumes I guess that the input field names match the
property names). This seams to work great.

Right before the "propertysheets..." line I have tried adding the
following:

  <dtml-call "manage_upload(REQUEST['file'])"> 

It does not generate an error. But it does not seem to manage the upload
part either, since my VProduct instance gets the content_type
"text/plain" (instead of image/jpeg which is the right type for the jpeg
file I try to upload). And when I try to "view" the VProduct instance, I
get a simple <img src="91231912" alt="sometext"> tag which displays like
a missing image in a web browser (no wonder since the content_type is
wrong). I have tried manually setting the content_type to "image/jpeg",
but the image still does not display correctly. My guess is that the
image never got uploaded.

Any ideas on how to handle the upload properly? I've done some 30
searches through the list archive, without any clear answers to how the
image uploads are handled (or should be handled). I've looked carefully
through the howto's but have not found anything.

Any help would be appreciated.

What I know is that you have to use Named Parameters in method

ex:
myFunction(url, image):
    return '<A HREF=%s><IMG SRC=%s></A>' % (url, image)

and the dtml call looks like :

<dtml-var "myFunction(url='http://www.zope.org', image='logo.gif')">

I am not sure of all...But I think it is the "spirit"...

Good luck !

You don't.  But that's what you were asking so that's what I was
answering.

I don't think the problem is that a transaction needs to be commited,
the problem is that the DA is engineered to block until it completes the
task at hand.  Even if you did call get_transaction().commit() from
python or an external method or whatever, I don't think it would unblock
your call.  You can try it, of course.

I don't know if we have immediate plans to bring the ODBC DA up to level
3.  Probably not any time soon unless it is a customer requirement.

Another option is to threadsafe the ODBC DA yourself.

I know, I know. :) But how otherwise do I get you people
to come out from hiding without posting a hack like that? :)

GUF has problems and we have to face it. If a product takes
a few days to install, if a product locks newbies up and send
them into panic attack, it has problems. Please just look
up past postings in the mailing list... headers like "Bad...
very bad" and "GenericUserFolder has locked me out" are
just heartbreaking. :)

If I have time I'll find something better, or make something
better. :)

Evan:

(1) When the the next version of Zope coming out?
    It fixes a tiny bug that I reported. :)
    Will it have a native feature like SiteAccess that
    you have mentioned before?

(2) Could you describe briefly how the traverse machinery
    works in Zope? I'd like to take a look into it. Which
    Python files are involved?

regards!

The boundary tag is implemented in the MIMETools product.  Because it is
only meaningful in the context of the mime tag, I did not explicitly
list it in the readme.

I'm not certain if the MySQL DA is level 3 (threaded) or not.  I am
certain that MySQL does not support transactions and Zope does.  What
this means is, if you call some SQL and later on an error occours, Zope
will "roll back the transaction" and discard any changes you made in
Zope.  If Zope is used with Oracle, Sybase, ODBC, Postgress or any other
database that supports transactions, then those databases will
synchronize transaction commits and rollbacks with Zope.  This means
that your data is allways consistent across databases, which is a good
thing.

This may not effect you.  Your database may be entirely read only, in
which case it's not a problem at all.  Just keep in mind that you are
missing an important piece.

Keep in mind that this is not an _relational_ database.  It's an object
database.

Yep.  You can access the ZODB through HTTP, FTP, XML-RPC and WebDAV. 
That's really what Zope is, it's a network aware application on top of
an object database.

The question is really too vague to get a specific answer.

Well, it's syntactically correct.  Whether or not it does what you want
it to do we can't tell because you didn't say what you want to do.

The expression "'PROENG' and 'MATRIX'"  will _allways_ return 'MATRIX'. 
So 'OK' will only be rendered if OUTPUT == 'MATRIX'.  In fact, this:

<dtml-if "OUTPUT == 'MATRIX'">
  OK
<dtml-if>

does exactly the same things as your code.

There apears to be a segment violation somewhere in Zope which was

Subject: [Zope] Zope and enterprise data access
Message-ID: <4.2.2.20000315131747.00ba5600@saladin.aisys.com>

The company I work for is starting to get more requests for web sites which 
need to have access to enterprise data.  We have several Java people on 
staff and most of these projects are currently being done (or planned to be 
done) using JSP/Servlets and Enterprise Java Beans.  The problem that I 
have with this solution is that there is very little in the way of content 
management available in this environment, without rolling your own.  What I 
would really like to be able to do is build the client interface using 
Zope, so I can easily blend static content, dynamic content and content 
management, with access to enterprise data.  I know that Enterprise Java 
Beans are accessible via CORBA, so theoretically it should be possible to 
access this data through Zope/Python.

My basic question is this, is there anything available (free or otherwise) 
which would make it fairly easy for Zope to interact with something like 
Enterprise Java Beans?  Are other people trying to use Zope in an 
environment where access to enterprise data is important?  If so, are there 
other solutions to this problem?  What I would really like to be able to do 
is use Zope in combination with a DBMS to build smaller systems, but when 
the need arises, I would like to be able to scale things up to allow for 
distributed data object access.

Any thoughts, suggestions or comments on this subject?

Thanks.

Hmm.. unfortunatly there is no good way to do this from DTML except to
use manage_FTPget().  Yuk.  This lack will be fixed in the near future
when we re-do alot of the Zope interfaces.  Currently we are in the
middle of documenting all of the existing interfaces which obviously
must come first.

I *think* you want REQUEST['file'].read().  manage_upload wants a string

You can create your own kind of splitter and replace Zope's (note that
Zope's splitter is written in C, and is found in
lib/python/SearchIndex/Splitter.c) you can write yours in C or Python.

I have not touched the authentication machinery yet so I must rely on
other Zopistas efforts. There is a LoginManager which is part of the PTK.
Seems to be well thought out, and it seems to provide a very general and
broad solution to the authentication problem, but I have no idea whether
or how it works.

Another useful add on is for GUF to ship  a complete example of its usage
based on standard Zope objects (Folders etc). Maybe as an exported
folder that the user can optionally import.

What would I have to do to get a sequence like that accessible from

I would solve this in the submit action by doing a select for the data before
doing an insert.

Example:

(form_html)

<form action="submit_html" method=post>
....
</form>

(submit_html)

<dtml-in select_data>
<dtml-if sequence-start>
<dtml-var error_message>
</dtml-if>
<dtml-else>
<dtml-call insert_data>
</dtml-in>

Dan,

It's gotta be a connection string or username/password problem as
defined in your interfaces file.  Are you sure the port number of the
remote server is correct in the interfaces file?  You can use isql from
the box that Zope is on to connect to the remote Sybase server?

Dan,

You need to install the Sybase client libraries on your Zope machine to
use the SybaseDA.

For more info, please contact the Zope mailing list at

I guess I'm confused.  I can't get to the actual jpeg image?  Here's what I'm
trying to do.  I want to create a form to upload data.  This data can be off any
type.  The data is stored in an ODBC database table along with it's mime type.
So, on the upload action form, I need to 1)  get the mime type and 2) get the
actual data.  Another part of the site mails off these items as attachments.
I've heard that the mime type should be uploaded along with the data, I just
don't know how to get to it.

You have a few (untested) choices:

1) Put the following in a DTML Document or Method:

     <dtml-call expr="REQUEST.set('first_sequence', [1, 2, 3])">
     First:<br>
     <dtml-in first_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

     <dtml-let second_sequence="[1, 2, 3]">
       Second:<br>
       <dtml-in second_sequence>
         <dtml-var sequence-index>: <dtml-var sequence-item>
       </dtml-in>
     </dtml-let>

2) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Tokens". Give it the value "1 2 3". Put this as the document
   source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

3) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Lines". Give it the value:

     1
     2
     3

   and put the following as the document source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

4) We could make a Python base class
   (lib/python/Products/MyClassBase/MyClassBase.py):

     class MyClassBase:
       def __init__(self):
         self.my_sequence = [1, 2, 3]

   and create a file (lib/python/Products/MyBase/__init__.py):

     from MyClassBase import MyClassBase

     def initialize(context):
       context.registerBaseClass(MyClassBase, 'MyClassBase')

   Now restart your Zope, go to the Control Panel, and Add a new product
   called "MyClass". Inside this product, create a ZClass called
   "MyClass". When creating the ZClass, select MyClassBase as a base
   class. In this ZClass, on the Methods tab, create a DTML Method
   (say, index_html) with the following source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

   Then, go to your root, drop an instance of MyClass with an id of
   "MyInstance". Now, navigate to http://your.server.com/MyInstance.
   Voila.

I probably missed two or three other ways to to it. But, I hope one of
these is what you're looking for.

Not directly from DTML.  You need to use a method on the Image object. 
manage_FTPget().

This is different from the first question that you asked.  In this case,
when your form uploads the file contents, ZPublisher will marshal that
into a StringIO object (which acts just like a python file object).  In
this case you can just do:

<dtml-var "REQUEST['name_of_form_element_that_is_the_file'].read()">

and get the 'contents' of the file.

In this case, your taking about a Zope 'Image' object, _not_ a standard
file object like you get when you upload data.  For this you need
manage_FTPget().

Has anyone noticed their dtml code mysteriously reverting to a previous

In other words suppose you have a dtml document called DocA. It
contains:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Several days later you change
DocA to:

<!--#var standard_html_header-->
<h1><!--#var id--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Later that day or several days
later, after a manual shutdown and restart, DocA has reverted to:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

Ok, I guess this is where I get confused. When is the REQUEST['file']
instance
a string and when is it not? If I try to replace the manage_upload call
with
your suggestion, I get a message saying:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which indicates that REQUEST['file'] is a string at this stage (and
probably
the filename or similar). From the input form I guess "file" is a string
(at
least that is what it looks like in the input form - the filename) at
least
until I press the submit button. When it actually changes from the
filename
to a file I do not know.

Any other suggestions on how to get hold of that file?

Thanks,

Marius Kjeldahl

Your form element should be:

<input type=file name="file_name:file">

The ':file' is necessary to marshal the file into a file object.  I was
going on the assumption that you had done that otherwise as you've
discovered it will turn it into a string, which you may or may not want.

MySQL takes a lot of criticism because it is (a) non-free, (b)
non-transactional. Non-fre I won't get into.

Non-transactional means that it doesn't support transactions. :) So what
are transactions? Say you own a bank and Joe transfers $50 from his
checking account to his savings account. The program removes $50 from
this checking account, but the disk is out of space and an error occurs
putting it into a savings account. Is Joe out $50? Not if it was a
"transaction" where all-or-none of a sequence of events happens. If at
any point an error occurs in the transaction, everything is rolled back
($50 is back in his checking account and the error is reported). MySQL's
lack of transactions rule it out IF you need transactions.

Another limitation of MySQL is that it doesn't support very large
databases. This usually isn't an issue.

Another solution is PostgreSQL, which is a free relational database
system (see http://www.postgresql.org). Postgres is very powerful and is
probably the most powerful free db by far! There are some drawbacks:
 * Last I heard, the PYTHON INTERFACE (not PG itself) for postgresql is
not threads compliant. You will have to kludge something with locks to
use it(?)... any ideas on this one, anyone?
 * You cannot remove or modify a column on your database. You can rename
the column and let it hang, or recreate the table. For changing schemes,
this can be a real pain.
 * Text beyond 16K must be stored in a large object - this is a pain.

It has some advantages:
 * Transactions
 * Super docs
 * Great reliability
 * Most of ANSI SQL Compliance
 * Stored procedures
 * Some real nice datatypes for everything from money to geometry

Alas, there is Oracle8i. It has some drawbacks:
 * Installation is a bitch! You usually have to edit kernel header
files, recompile, set mount points, apply patches, arg!!
 * Complexity; Oracle VERY complex even after you get it up and running
 * The Oracle/ZOPE interface does not have a Setup file for 8i. You'll
have to write one to compile it. (Or, email me for the one I got a hold
of)
 * Fewer column types than postgres

And the advantages:
 * Transactions, great reliability, and great SQL support
 * Java support
 * Plenty of docs. My favorite Oracle stuff is at photo.net (the web
page of some MIT guy)
 * Good interfacing with Zope, thread safe

In general, if you're willing to spend the overhead of a killer learning
curve, use Oracle8i.

Ok, I have changed my form element to what you suggested. These are the
results I am getting with various <dtml-call> tags in the VProduct_add
method (called after filling in VProduct_addForm):

* <dtml-call "REQUEST['file'].read ()">

Error Type: TypeError
Error Value: argument file was ommitted

I guess this is because no field in the form is named 'file'. So I try:

* <dtml-call "REQUEST['file_name'].read ()">

..and I get the same error. I even tried to name="file:file" in the form
element, and using REQUEST['file'].read () in the call, but then I get:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which I guess means that it now has the 'file' variable, but it is still
a string.

Any other pointers, or references to where I can read more about the
file stuff?

Thanks in advance,

Marius Kjeldahl

REQUEST['file'].read ()
                    ^
            Notice this space?

That space isn't supposed to be there.  You're supposed to be calling a
function with no arguments, the () has to be right next to the "read". 
The way you have it right now, it's looking for an attribute called read
instead of a function.

Actually you can get the image data as <dtml-var "my_image.data"> where
"my_image" is the name of your image object.

The following DTML will return the actual image to a browser (tested):

<dtml-call "REQUEST.set('Content-Type', my_image.content_type)"><dtml-var
"my_image.data">

It is crucial that the DTML method contain no extra whitespace, though, as this
will be interpreted as part of the image data.

Subject: [Zope] Zope Weekly News
Message-ID: <Pine.BSF.4.21.0003151720200.1009-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively (but I'm willing to share).


Announcements

  * The latest versions of the Zope Content Managers Guide, Z SQL
    Method User's Guide and DTML Reference Guides is available in
    postscript(ps) format.  With luck, the technical problems of the
    previous versions have been fixed.

    http://www.zope.org/Members/Pam/PSversion

  * Check out the new Zope Documentation Projects page that lists
    current Zope documentation projects and their status.

    http://www.zope.org/Documentation/Projects/Projects

  * Martijn Faassen <faassen@vet.uu.nl> has established a Zope-XML
    mailing list.  The intent is to discuss Zope's XML infrastructure.

    http://www.egroups.com/group/zope-xml/info.html


New Products

  * Software Product: iTrack Issue Tracker Product, by "shalabh"

    iTrack allows a team of people to keep track of various issues
    about a project. Currently this is in development stage (Version
    0.2.0) but usable, as long as you follow the instructions.

    http://www.zope.org/Members/shalabh/iTrack/

  * Software Product: ZGDChart Product, by "teyc"

    ZGDChart uses gdchart to draw charts.  This product comes with
    Windows binaries and source for non-Windows platforms.  This
    initial development release is 0.3.

    http://www.zope.org/Members/teyc/ZGDChart

  * Software Product: DTMLTemplate, by "halazar"

    DTML Templates are documents that allow blocks of text to be named
    and made available to other documents. The basic building block of
    templates is the DTML block tag, which can also be used with other
    DTML document types. Templates export their blocks. Another new
    tag, the suppress tag, allows block definition without rendering.

    http://www.zope.org/Members/halazar/Products/DTMLTemplate


Updates

  * Software Product: jcNTUserFolder, by Jephte CLAIN

    This product authenticates Zope users against an NT domain
    controller.  All users are encouraged to upgrade to this version,
    0.0.3.  Unfortunately, the upgrade is incompatible.  You will lose
    any role settings.

    http://www.zope.org/Members/jephte/jcNTUserFolder


Zope.org items

  * How-To: The Debugger Is Your Friend, by Michel Pelletier

    This HowTo is an invaluable resource for those days where if I get
    one more mysterious traceback, just one more and I swear I'll
    crack.  It explains how to step through Zope code line-by-line
    with the python debugger.

    http://www.zope.org/Members/michel/HowTos/TheDebuggerIsYourFriend

  * How-To: How to test your products without (re)starting Zope, by "teyc"

    This HowTo describes testing Zope products within a python
    interpreter without starting the Zope server.  This rather speeds
    up the code-test-curse-code cycle, because it allows you to
    quickly reload your Product with each change.

Subject: [Zope] Randomizing SQL Data ?
Message-ID: <B4F57760.14F5%Jatwood@bwanazulia.com>

I have some data returned by a SQL Method that I want to randomly pick from.
Since I cannot get the SQL Statement to return random data sets I was going
to use the "_.whrandom.choice" to go over the SQL list and create a new list
of the randomized choices.


This will go over the SQL Content
<dtml-in sqlMethod size=10 start=query_start>
</dtml-in>

But how do I create a list? (in Python I would just say list = () and a
list.append()

TIA,
JMA

Hi..

I just uploaded many files with load_site (thanks Itamar!), but
I ran out of disk space while doing this.
Seems as the last transaction corrupted the Database seriously.
When I try to delete the folder where the errors are I get:
Error Type: CorruptedDataError
Error Value:

The same with packing database.

And when invoking Undo, i get something like:
long int too long to convert

Any ideas what I could do to repair my database and deelete the corrupted
folders and start over again?

Thanks in advance,
    Mario

Havn't been able to so far. It seems you have to have a reasonably complete

That is a possible option. Does anyone know what the issues with this are?
From memory I think the non-thread-safeness of the odbc drivers themselves
was not the only problem. I suspect the python odbc interface might have
been not thread safe also. Can anyone confirm this?

Hi

i've spent the day trying to make this work so i thought i'd see if
brighter minds could illuminate the darkness of my night.

I'm trying to setup an email archiving system in Zope. I've got the
email retrieval setup in an separate python script and a couple of
ZClasses setup in Zope to archive/catalog the emails. My problem is
getting the parsed email info(to, from, body, etc) from the external
script into my Zclasses. i've tried xml-rpc but i keep getting server
errors. i connect to the server and try

zope.project.archive.addEmail(id)

but i keep getting a 500 Internal server error message. addEmail is just
a wrapper around the constructor which expects only one parameter the id
of the email Zclass object to create( just something to debug before i
pass in all the params). So what gives? i can call the method from the
web with

http://localhost/project/archive/addEmail?id=xx

but how do you call a dtml method with args from xml-rpc. fyi i'm using
amos's patched xmlrpclib for authentication (i fixed the import errors)

i've trying to reimplement this in an external methods but i would
really like to know how to do it with xml-rpc. btw 

Thanks

Kapil

The Login Manager looks good because, unlike GUF and UserDb, it allowed
me to use the admin/supervisor password to authenticate straight away 
and so didn't lock me out of the directory.
I actually gave up on GUF because I _couldn't_ get it to let me in in
the first place to set up my db methods. The password that is supposed
to be built in didn't work at all, neither did the supervisor one.

To me this is the biggest problem with the other existing systems, that
they lock you out of your site and there is little you can do about it.
(In UserDb I had to comment out parts of the security code to get it
to let me in and set it up properly. After it was set up it worked fine
and I could put the code back.)

All authentication stuff from a database is going to require the
person to customise their own sql we can't make custom authentication
methods any easier than that, but in the simplest case this should
be _all_ they have to do. The supervisor password should _always_ work
in any authentication method from the beginning and it should be made
clear that people are going to have to authenticate using that particular
password until they have the rest of their site set up.

Anyway, the LoginManager looks very clean. It already doesn't have a
lot of the old problems and I like the abstraction. Now I just have to
finish getting DCOracle working (annoying truncated .so files...).

Yeah that was probably me, not to slam MySQL, it's fast, it's free, and
it's stable.  It's lack of transactions however means that you have to
be aware of and live with the possibilty of inconsistent states of data
between MySQL and Zope.

For read only operations, or low-write, or if an external application
handles inserting your data and Zope only reads it, this is not really a
problem.  Also, it's only really manifest if you change the database and
then change something in Zope and an error occours.  If you can isolate
your SQL calls as much as possible, then this shouldn't be a problem.

I posted a work around for that on this mailing list a couple of days ago.
And yes whilst it is frustrating it is no where near as hard as writing 
an authentication product from scratch (which from experience is difficult).

Last time I used it came with a very simple example already. All you need
to do is add in your logic and you're away. The SQL Howto on the website is
very informative (cheers to whoever wrote that).

Sorry I think that the GUF is also very clean and quite easy to work with.

I think GUF is great as it is. Thanks a lot to Zen for contributing it.

I would have to recommend postgresql. I've got a prototype ecommerce site 
running with Zope at the front, some python in the middle and postgresql
at the backend. Currently it is a prototype so we only have about 20,000
items in there at the moment however it seems to work very well. (Once I 
brushed up on some of my SQL).

Check it out at http://www.postgresql.org

I see a couple of issues with this:

1)  This may not scale well; if select_data becomes large you may
be spending a while in the dtml-in loop.

2)  There could still be a race condition here, between the check for
data and the insertion (especially coupled with the above point - the
probability would increase proportionally with the load of the machine
and the size of the table). I say "could" here (guardedly :-), because
I don't know how Zope's transaction semantics are implemented, and how
they affect the DA that you're using (does anyone have any pointers to
documents?  I've just started reading "How to Write a DA", and this
mentions the distributed commit protocol).

I'm not sure if a solution to the original problem is to surround
the insert with a <dtml-try> tag;  I'm going to try this myself
sometime today (if I get some spare time :-).

My experience with SyBase is that the adapter development is
kind of slow, and only Linux platform is supported. And
currently it has some glitches with some data types (decimal
with 10 or more digits), it does not support stored procedures,
and the implementation in Zope 2.1.4 crashes when you have
date fields ending between 59 and 60 seconds (e.g: 59.23 sec).
Also, when there is database problem, the adapter very often
just hangs and lock the database out, requiring a Zope reboot.

So, SyBase in Zope is not really in great shape. I don't know
about other databases, maybe other database adapters have
problems, too. SyBase adapter is workable for me (after I
patched the problem areas), just not that great in its current
shape. It has transaction, though, which you definitely want.
The thing is, SyBase itself seems fairly solid, it's just the
Zope adapter that is still not perfect.

regards,

Hung Jung

Subject: [Zope] DateTime exceptions
Message-ID: <00031611243805.02516@localhost.localdomain>

Greetings,

A workmate of mine has had this problem also, and now it's happened to me.

I cannot catch exceptions from the DateTime object!

My code:

<dtml-try>
    <dtml-call "REQUEST.set('delDate','%s/%s/%s' % (delYear, delMon, delDay) )">
<dtml-except>
    <dtml-call "REQUEST.set('delDate',0)">
    <font bgcolor="red">You have entered an invalid date.</font>
    <dtml-call "REQUEST.set('Error',1)">
</dtml-try>

Now, from my understanding, this should catch ALL exceptions.  So why, when i
give invalid values (like -1) does ZOPE give me an error page?

Is this some deficiency in the way the DateTime object handles exceptions?  Or
is there some funamental zen i'm not groking?

Have a better one,
	Curtis.

I would write the select_data query to only select a single record, i.e. the one
I'm worried about duplicating.

Heh. I certainly wouldn't want to do it from scratch myself...
I just tracked down your work around again and now remember why it didn't
help me. I actually have a UserDb in my root directory and that's what I'm
trying to get rid of (Since I'm moving to Oracle anyway I thought I'd
change to a supported product since UserDb has been giving me a few obscure
problems at times.) So since it doesn't support the admin user either your
suggestion doesn't help. I will, however, try making a normal user folder
in a subdirectory and then try to set GUF up in a subdirectory of that...

Grin. Seeing I never managed to get into GUF's management interface in the
first place I can't really comment on how clean it is.

IIRC, all you need is the libraires, a seperate download. I have a
couple machines that only have the libraries, and work just fine. Of
course, they are on various unixen, YYMV on NT.

Hi there,

Firstly, I'm not a member of this mailing list, although I have an archive
of over 2000 messages from it.  Could anyone replying to my message please
reply to tim_haines@hotmail.com as well as the list?  Thanks.


I've been developing a site using nt4, Access, and the odbc plugin.  Things
work great - most of the time.

I've noticed that occaisionally I get any error message that mentions
tpc_begin.  When I do a refresh, the problem is gone, and the site works
fine again.  I've also noticed that this normally occurs the first time a
database query is executed after a reboot.

Does anyone know why this would happen, or have any insights at all?  I look
forward to hearing from you.

Tim.

One thing I should point out firstly is that the LoginManager inside
the PTK isn't finished yet and the developers don't suggest actually
using it just yet.

While I said it looks great (and it does) and it accepts the admin
password it does _not_ yet have the api in place to let you authenticate
from SQL. So you probably want to wait a bit still.

But after saying that if you still want to look at how they are going
you need to actually install the Portal Tool Kit first.
Have a look at it's install instructions at:

Can you provide more specific detials? I am running two seperate systems

Hello.

Many thanks to all for your answers on my recent question about MIMETools.
Really, tag <!--#boundary --> is implemented now, and works, but...
I need sending mail with multiple file attachement...
Combination of several tags <!--#boundary --> working...
When I tryed insert tag <!--#boundary --> into tag <!--#in -->,
Zope said: "Unexpected tag, for tag <!--#boundary ..."
Because <!--#boundary --> is only meaningful in the context of the 
<!--#mime --> tag.
We have loss of this context? Below example of my stupid code.

[ --- begin code snippet ---]

<!--#mime type=text/plain encode=7bit -->
just example text...

<!-- #in "files_to_mail" -->
<!--#boundary type=application/octet-stream disposition=attachment 
encode=base64-->
<!--#var sequence-item -->
<!-- #/in -->

<!--#/mime -->

[ --- end code snippet ---]

Any ideas?

Dima.

Are you just afeter a single random item from a ZSQL query? 
If so:

<dtml-with "_.whrandom.choice(_['getcategories'])">
	<dtml-var category>
</dtml-with>

Works for me. In this case, 'getcategories' is a ZSQL method that
returns a list of categories, consisting of:
"select category from linkCategories"

Message-ID: <38D077D6.CC74ABB3@suprize.com>

Hi,

    Zope seems to evaluate expressions in an unconventional way.
Say I have three properties, a=3, b=5, c=7 set in a Folder. In
a DTML Document I tried to say <dtml-var "a/b*c"> and got result
0. The expression was evaluated as a/(b*c) and rounded off. Is
not the expression supposed to be evaluated as (a/b)*3? The
result is not correct still if we put it this way:
<dtml-var "(a/b)*3">. I still got 0 as the result. Did I miss
anything fundamentally or is this a, bug?

Hi Zopistas,

I now that the failure is because the object in the namespace is "PARENTS". So what is the name of the root folder?

Hi,

    Suppose the following folder/Obj structure:

		Zope Root
		    - test
                        showImage     (DTML Document)
		        - image
			    testImage (image object)
		    - test2
                        testProgram   (DTML Document)

    showImage contains one line of code:
       <A HREF="test"><dtml-var "image.testImage"></A> 
    that shows the testImage properly alone. But if I put
    <dtml-var "test.showImage"> in testProgram (in test2),
    I got all "<" as "&lt;" and the ugly code like the
    following was returned intead of the image with link.

&lt;A HREF=&quot;test.html&quot;&gt;&lt;dtml-var
&quot;testImg&quot;&gt;&lt;/A&gt;

    I have tried the following but none works out:
	- Use DTML Method instead of DTML Document to hold
	  showImage
	- Use "/" instead of "." to point to objects
	- Use single quote or no quote instead of double quotes

    Please advise the proper way to resolve this annoying issue.
    Thanks a lot!

Most of the unfinshed pieces have to do with giving users
propertysheets. That makes it not quite useful for PTK yet.

I'd say for non-PTK use it's in pretty good shape.  Would I recommend
using it currently? Well, for a production sight, I think maybe it's a
bit too new.  It could stand more testing and security review.  But, if
you're developing a site that you don't need to go live tomorrow, I
say sure, go for it. It's quite useable for non-PTK applications.

Sure it does! Got a SQL-based GUF? You should be able to take your GUF
userExists/userRoles/userAuthenticate/etc methods and plop them
unchanged into a LoginManager Generic User Source (GUS), and have it
Just Work. 

You're probably thinking of the comment that it's not ready to do
SQL-based PTKs. This is because the propertysheet support that PTK needs
isn't there for SQL. But, that's a feature that no other SQL-based
userfolder has anyway -- it's a new thing, and at the moment only PTK
needs it.

Sadly, the way DTML tags work right now, this isn't possible.  Since
'boundary' is part of the 'mime' tag, like 'else' is part of 'if', you can't
put it inside another tag.  The only workaround I can think of is pretty
nasty; look at the source for MIMETag and use the MimeWriter class directly.
It's not that bad, unless you don't know Python...

Urk.  First, we can pick this apart in at least two ways:

<dtml-with "PARENTS[-1]">

or

<dtml-let rootObject="PARENTS[-1]">

In either case, the part in quotes takes the last element of PARENTS, giving
you the root folder.  In the first case, we use this directly in a
"dtml-with", and can refer to properties and contents of the root folder
inside it.  In the second case, we give the root folder the local name
'rootObject' which we can then use to access it.

You've run into a misfeature of Python.  Since 'a' and 'b' are integers,
'a/b' is performed as an integer division.

Thus 'a/b*c' == '(3/5)*7' == '(0)*7' == '0'.  If you want floating point
division, you need to make 'a' or 'b' a float, either directly or by writing
'_.float(a)/b*c'.

Subject: [Zope] Version bug?
Message-ID: <38D10EEF.156ABF9E@globalcrossing.com>

Greetings!

I think I may have found a bug in the way Zope handles versions.
To recreate:

1) Set up a version, say, "TestVersion."
2) Rename the version to something else, say, "NewTestVersion."
3) This breaks the following:
   * When you enter the version, the "you are working in" line displays
     "TestVersion"
   * The "Version Management" Control Panel link shows TestVersion as
     well (this breaks the link, too)
   * Any file modified by the version shows up as TestVersion, too.

This happens on:
  Zope version: Zope 2.1.4 (binary release, python 1.5.2, linux2-x86)

Is this a bug?

Hi Zopistas,
	Thank you for the answers. My problem arose because I was passing a DTML Method a list of strings: [ 'PARENTS[-1]', 'FolderA', ...]. And while I could do:
	<dtml-with "_( folderObject=_.getitem('FolderA'))">
I could not do the same with 'PARENTS[-1]'. The simple solution suggested by your answers is to just pass the objects themselves (duh!): [ PARENTS[-1], FolderA, ...].
	But out of curiosity I'm still wondering if there is a way to refer to the root folder by name so one could write
	_.getitem( 'rootFolderName' )

Subject: [Zope] How do I set properties from DTML? (Repost)
Message-ID: <00031617290300.13146@promotor>

I'm reposting due to mail problems ...

I'm working on a thing I'll probably call "ZBox"; it's a "widget
method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Sure, you just need to trace my previous postings. :)

SyBase adapter has two specific problems that I have ran
into. They are both 100% reproduceable and both have been
reported to the Collector. One of them is now fixed for
Zope 2.1.5 (the _validTime thing.) The other one still sits
still waiting for Digicool to fix it. If I say the development
of the adapter has been slow, it's because it's been slow. If
I alone have been able to find (and fix) two problems
and one limitation, somehow I don't think they are the
only problems and limitation. :)

Some of the bugs are later found independently by other
people, too. (See below.)

Many people also say that they have zero problems with
Microsoft Windows. I guess they just have been lucky. Ha ha.
But just because one person is lucky, it doesn't mean the
rest of the world is equally lucky. :) Let me teach you
how to para-phrase your question:

"Can you provide more specific details? I am running two
separate system with Sybase, and I would like to know more
about these problems."

Very nice. The following are three articles in chronological order.

Subject: [Zope] XML-RPC Woes
References: <38D0221B.794D6C3A@wm.edu>
Message-ID: <38D129D3.B15C9835@wm.edu>

After getting a few private emails with questions about what i was doing
i thought i'd share what i'd learned and some code.

First an apology, i read through my original email and realized that i
was a bit to vague to really get any help, mainly because i don't
understand what i'm passing through xml-rpc to dtml methods that are
expecting Zope stuff (client, mapping, kw).

Second, what i'm doing. I'm creating an email archive in zope. i wrote
up some python code that retrieves/parses email from a pop3 server and
then inserts via xml-rpc into a zclass so that it can be archived and
cataloged. I got the whole thing working last night by passing the
parsed info in a dict via xml-rpc to an external method which
took care of adding the Zclasses in Zope, basically following the
example from this howto http://www.zope.org/Members/teyc/howxmlrpc

Third, How to do XML-RPC with Amos's patched xmlrpclib.py for
Authentication:
    1. Assuming you already have the original xmlrpc implementation from
pythonware.com installed, copy Amos's xmlrpclib.py over it (WARNING this
will basically delete the original).

    2. Fix the subclassing error. Find 
	class BasicAuthTransport(xmlrpclib.Transport):
	and change it to
 	class BasicAuthTransport(Transport):

    3. Fix the import error. after the comments there are some imports
add:
	from base64 import encodestring



<dtml-with Standard_Code_Disclaimer>
all code is provided on as is basis for the purpose of an example. use
at your own risk.

Fourth. External Method Code:

	def import_mail(self, props):
		id = props['id']
	mailobj=
#netscape mangles this line
self.manage_addProduct['YourProduct'].YourZClass.createInObjectManager(id,
self.REQUEST)

	mailobj.propertysheets.YourPropertySheet.manage_changeProperties(props)
	return "Zope is Cool"


this is one of those times you just look at zope and sigh. so much power
if you know how to use it. i actually got the basis of this code from
the Zope CD that they passed out at the python conference(8). this
method is part of the archive folder called below.

Fifth. The XML-RPC call: from the python script without error checking

        self.zope = xmlrpclib.Server(YourZopeServer,
                            xmlrpclib.BasicAuthTransport(userid, passwd)

        Props = {
            'Id':Whrandom.Randint(0,1000000),
            'To':Prop_list[0],
            'From':Prop_list[1],
            'Subject':Prop_list[2],
            'Date':Prop_list[3],
            'Body':Prop_list[4]
            }
        Print Self.Zope.Test_project.Archive.import_mail(Props) 


</dtml-with>


I hope this helps. if anyone has any examples of passing args to dtml
methods via xml-rpc i'd love to see them. 

Cheers,

Kapil

No, its integer :)
3/5 is 0, anything multiplicated with 0 will be 0.
so 3/5*7 is 0 no matter where you set brackets :)
Integer does not round, it only cuts off everything after the "."

Eventually you want: a=3.0, b=5.0 and c=7.0
(even only one variable beeing "float" wuld be sufficient)

Okay, I *think* I am beginning to grok zclasses, but I have a couple
of questions:

What is the scope/namespace of a ZClass' methods?  In my tests, I
cannot access other methods of the same ZClass.  I *can* access
methods in parent folders of my ZClass, but not the current folder.
Ie: Create ZClass called zcTest.  Create two methods in this ZClass,
called index_html and test.  Neither can see the other.

Secondly, when I try to access anything off of instances of my zclass
except for property sheets, I get access denied.  Where do I set up
the permissions to allow my methods to be viewable?

Subject: [Zope] ZODB question, again
Message-ID: <38D13016.6F9160EC@sage.att.com>

ok, persistent fool that i am, i'm still trying to figure out
how to use ZODB in an External Method to do some simple (ha!)
database stuff.

so i built a very simple app, to implement a counter.
each time you invoke the "Count" method, you get a number
back, and it increments.

running the script (see below) by hand, it works fine.
referencing it from Zope, using this dtml fragment:

	<dtml-var "Count( 'chickens' )">

or just pointing my browser at:
http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=chickens

to reference an External Method called Count, which 
refers to the Count function in this script, i get:

   Error Type: AttributeError
   Error Value: Counter

if i then click the reload button, i get:

   Could not lock the database file. There must be another
   process that has opened the file. 

and i'm locked out until i restart zope.
can someone please help?  this is getting really
discouraging.  a simple explanation of where i'm 
going wrong would be greatly appreciated.  a small
working example of a working app would be terrific.

thanks


--------------------------------------------------------------
script follows:

import ZODB, ZODB.FileStorage
import Persistence

class Counter(Persistence.Persistent):
	"""A Persistent Counter"""
	def __init__( self, name ):
		self.name = name
		self.value = 0

def Count( name ):
	"Get counter value, then increment, creating if necessary"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/CountDB.fs' ) )
	connection = db.open()
	root = connection.root()

	if not root.has_key( name ):
		counter = Counter( name )
		root[ name ] = counter
	else:	counter = root[ name ]

	counter.value = counter.value + 1
	
	get_transaction().commit()
	connection.close()
	return counter.value

I'm able to get Zope to dump a core file if run in debug mode ('-D').  I
haven't proved this, but I suspect that when a fork()ed child dies it
does not dump a core file.  Since debug mode does not cause Zope to fork
off Zope as a child from the parent watchdog, a core file is produced. 
None of this is mentioned on the fork() man page, or the clone() man
page, or whatever.  I probably need a good UNIX programming reference to
verify it.

Give it a try, fire up Zope in debug mode and run your load scripts
against it to reproduce your segfault.

Message-ID: <4.2.2.20000316001051.00a9f710@postoffice.pacbell.net>

I am having trouble with userDB cookie authentication in IE 5 through the 
@Home network. Apparently @Home uses a proxy server for all of their 
traffic. When accessing the docLogin page for authentication the user 
receives a "Cannot Display This Page" error from IE 5. Turning off 
cookie-based authentication seems to solve the problem. This problem does 
not occur in Netscape under the same conditions and does not occur in IE 5 
when used outside of the @Home proxy.  Does anyone know of specific 
problems with IE 5 and proxy servers? Is there any solution outside of 
using standard authentication?

Try this

<dtml-var "_.float(a)/_.float(b)*_.float(c)">

You calculation is using integers and there is no automatic conversion being
done.

You need to explicitly tell zope that you want float calculations.

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:


ERROR(200) ZServer uncaptured python exception, closing channel
<zhttp_server listening :8080 at 81f5b90>

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

You cannot open the object database twice.  In this case, Zope opens it
first, and then you open it second (why you are getting the
AttributeError I don't know, a traceback there would help).

Basically what you are doing is sort-of a no-no unless you know what you
are doing.  First, a database cannot be opened twice, even from the same
process.  Second, you do not need to open the database again, because it
is already open and accessible to you from your external method:

def anExtMeth(self):
  connection = self._p_jar

All persistent objects (in this case, 'self' being the container of the
external method, probably a Folder) have an _p_jar attribute which is
their connection to the database.  Always use that instead of opening
your own.

Also, you need to be very careful with what you are doing.  You are
inserting objects right into the root level of the object database, this
is not really a good idea.  For example, let's say you fix your code to
not open the database again and you get it working.  Then (don't!) try
this URL:

http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=Application

Doh!  Guess what?  You just trampled your entire Zope, hosed the entire
enchilada, because Zope also lives in that top level namespace, and its
name is 'Application'.

Pick your own name (like GarryHodgsonApplication) and assign your
counter objects as sub-attributes of that.

Subject: [Zope] Zope Cookie Handling
Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF373@ap3expr3applge.appl.ge.com>

All,

Here is another interesting issue that I have encountered while trying to
process cookies in Zope.

On a different app. server I have a Java class which generates an encrypted
cookie when a user logs into the site.  When the user navigates over to my
Zope site, I wish to check the value of the UID.  I do this by retrieving
the cookie within the following snippet of DTML:

<dtml-if "REQUEST.cookies.has_key('UID')">
		<dtml-call "REQUEST.set('cookie',
REQUEST.cookies.values())">
		<dtml-var "validateCookie(REQUEST, REQUEST['REMOTE_ADDR'])">
</dtml-if>	

This DTML calls a DTML method (validateCookie) which in turn is calling the
following External Python Method:

import xmlrpclib, base64

def validateUID(self, REQUEST, ipaddr):
        cookie = REQUEST.get('cookie')
        servlet =
xmlrpclib.Server("http://salesnet-dev.appl.ge.com/geaservlet/X
mlRpcTest")
        cookie = repr(cookie)
        cookie = cookie[2:]
        cookie = cookie[:-2]
        return servlet.validateCookie.check(cookie, ipaddr) 

This XML-RPC call attempts to invoke the Java decrypt method.  Herein lies
the problem:

Upon investigation of the value contained in the UID cookie, Zope returned
the following:
\316\313\321\310\316\315\314\311\321\312\316\317\317\223\310\321\315\317\313
\316\317'

If I print out each character created during the Java encrypt method, the
following values are returned:

\206\203\209\200\etc.etc.

A colleague of mine pointed out that Zope was returning the values in Octal
rather than decimal.

Is this behavior by design?  Is there another mechanism I can use to
retrieve the raw cookie value before Zope places it in a dictionary?  Rather
than code a string parsing routine in Java, are there any suggestions as to
how to convert each character back to decimal, or obtain the string prior to
being converted into octal?

Once again, I appreciate the assistance/responses.  Everyone on this group
has been wonderful to interact with.

-Brian

This apears to be fixed in the CVS.  The reason is dispatcher.accept may
return None if the accept() sys call returns EWOULDBLOCK.

Assignment cannot be done in DTML, it is a security risk.  DTML was not
designed to be a general purpose programming language; it's meant to be
a reporting language.  Use python (either external methods or
PythonMethods) if you want to do this.

Subject: [Zope] Problem with ZODBCDA
Message-ID: <38B478360010B51B@smtp.visto.com> (added by administrator@visto.com)

I just installed ZODBCDA on a new Windows install of Zope 2.1.4 using ZServer running as an NT service.  After editing db.py to fix the THUNK typo (I've submitted that to the collector) it sees the System ODBC DSNs that exist, and it lets me pick one.  But when I try to open the connection, it tells me I have an invalid connect string.  The weird thing is that I turned on Windows ODBC tracing, and NOTHING is being logged from the Zope connection.  So I don't think it is actually passing anything to ODBC.  If I do the same thing from some other ODBC client, the connect string works and the session gets logged by the ODBS tracer.

There was a very similar problem in the list archives several months ago, and it seemed that running the service as a user, instead of the system, fixed the problem.  Didn't work for me.

Any suggestions on how to track this down further, or better yet to fix it, would be appreciated.

Message-ID: <38B478360010BA29@smtp.visto.com> (added by administrator@visto.com)

Within the last half-hour I posted that ZODBCDA connections were not working correctly on my machine, with Zope running as an NT service.

I rebooted the computer and now the connection gets made. (I hadn't rebooted since I changed the user the service was supposed to be running as.)  So with the Zope service running as me, rather than as the system, it seems fine.
And now my problem is exactly the same as the one in the archives last year.  This doesn't seem too serious, but if anyone knows why it cares who Zope is running as, I'd still like to know.

Thanks,

Fortunately MySQL has transactions high up on the todo list (but it's

Zope doesn't do anything above and beyond what python does.

Python rounds integers, quite simply:

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> 1/2
0
>>> 3/5*7
0
>>> (3/5)*7
0
>>> 3/(5*7)
0
>>> 

integers as input gives an integer as output.  Obviously there are two
schools of thought on this.  If you want a floating point number, use
'float()' (or in DTML, _.float())

>>> float(1)/float(2)
0.5
>>>

because of acquisition:

<dtml-var rootProperty>

Uups, sorry

<dtml-var "test.showImage(_.None, _)">
           ^^^^^^^^^^^^^^ 

but i think you have to call also

<A HREF="test"><dtml-var "image.testImage()"></A>

I tried to use MySQLDA without success.

unixODBC connection to MySQL that works.
How can I access this database through ZOPE.

When I try to make the MySQLDA extension a lot of errors come out of it
:

Can you help me ?


Does DigitalCreation have a solution on connecting to MySQL on a Linux

You have to convert it from integer to float. Try:

<dtml-var "(_.float(a)/b)*c"> 

Though you're rigth, you need the parenthesis for the correct
evaluation.

Hello there

I' ve got some difficulties with the very final step of ZOPE-Installation:
I made the start-script as root (-> python wo_pcgi.py) and got all the neccessary scripts. Then I chown and chgrp all files to my ZOPE-user and tried to start up the server. Unfortunately the script has got some endless-loop or so and I have to break (Ctrl-C) in order to get my prompt and logout. I do have access to the server via WWW but only until I break the script. 

Do you know some hint?
Thank you very much!

The root folder can indeed be accessed by PARENTS[-1].

<dtml-with "PARENTS[-1]">

is all you need.

Keep in mind also that if the property of the root folder you're trying to
get at has a unique name, you can get to it via acquisition. (If the
property is called "foo", <dtml-var foo> would look up the property and find
it, all the way at the root.)

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

Your properties look like integers, and I believe that is your problem. Try
this:

<dtml-var "_.float(a)/b*c">

By converting a to a float and then doing the rest of the expression, python
should consider the whole expression to be floating point.

Subject: [Zope] BIG ZODB - Scalability
Message-ID: <E12Vac2-0001CF-00@home.delysid.org>

Hi.

I just got the job to find out how we (the technical university Graz)
could build up a large image-database for different users..
Zope came to my mind because of its oject oriented structure.
And because I'd really like to do Zope work at work :).

I now have to find out how Zope can be used with really large
databases.
(100000 to 1mio objects theoretically in the future).

Can anyone provide me with URLs or information on:
The relational Database Storage Manager (couldnt find any references)
  (is this intented for large databases?)
Or splitting the Zope hirarchy into multiple ZODB FileStorage Manager
instances. SO that I could e.g. save on subfolder of the root folder
in on data.fs and the next subfolder in another data.fs

I am thinking of the filesize limit of some operating systems.
2GB isnt really much.

I think that a FileStorage would be better for our content (images),
because performance issues (never saved 20GB in an relational database before :) )

Any help is appreciated,

There are three errors here :-)

First, Python atribution doesn't return the value like C. The
value of "myObject = 1" is None.

Second, as you said, 'PARENTS[-1]' is not an object. Using
_.getitem Zope will look for an object with this name, which
doesn't exist.

Third, there is absolutely no reason for the _.getitem.

What you want can be acomplished with:

<dtml-with "PARENTS[-1]">
   ...
</dtml-with>

or

<dtml-let rootObject="PARENTS[-1]">
   ...
</dtml-let>

depending on what it is you want. :-)


Also note that if you're using SiteAccess' virtual hosting,
PARENTS[-1] will (IIRC) not give you the root folder, but the
virtual root.

testProgram should *call* the showImage method, otherwise you just insert a
string representation of it.

<dtml-var "test.showImage(_.None, _)">

Thanks, I've never accessed the CVS. How soon might the fix show up in a
release? (Or is there a simple change I can make to one of the .py files
until that happens?)

I would implement this whole thing as a Python product and avoid mucking around
directly with the persistence machinery altogether. This would allow you to add
a Counter object anywhere in the Zope tree.

import OFS, Persistence

class Counter(OFS.SimpleItem.Item, Persistence.Persistent):

    def __init__(self, id, title):
        self.id = id
        self.title = title
        self.counters = {}

    def Count(self, name):
        if not self.counters.has_key(name):
            self.counters[name] = 0
        v = self.counters[name] + 1
        self.counters[name] = v
        return v

manage_addCounterForm=HTMLFile('methodAdd', globals())

def manage_addCounter(self, id, title, REQUEST=None):
    ob = Counter(id, title)
    self._setObject(id, ob)
    return self.manage_main(self, REQUEST)


Add a Counter call 'counter' to a folder, then call:

<dtml-var "counter.Count('chickens')">

Subject: [Zope] New LocalFS Release
Message-ID: <03f001bf8f8f$4dcdee20$eb0217ac@dev.prognet.com>

Version 0.1.6 of LocalFS is out. I'm calling this one the Ides of March
release. :)

New in v0.1.6:

 - Fixed a bug with filtering in directory browse view.

 - Fixed bogus text/html content-type on non-HTML files.

 - Use a more aggressive search to determine whether files are 
   binary or text. This causes directory browsing to take a bit 
   longer but hopefully prevents file corruption problems.

 - Added a Properties tab which allows specifying custom properties.

 - Improved the formatting of directory browse view again with tables.

 - Convert .xml files to XMLDocument objects if the XMLDocument 
   product is installed.

 - Convert .stx files to StructuredDocument objects if the 
   StructuredDocument product is installed.


In 0.1.7 I'm adding fully-customizable mapping of file extensions to
content-types, Zope object classes, and icons in the directory browse view.
Hopefully that should be out pretty soon as well.

Tom,

Try this (only slightly tested)

<dtml-call "REQUEST.set('ua',HTTP_USER_AGENT)">

<dtml-if "_.string.find(ua,'MSIE') != -1">
 <dtml-comment>
  Its MSIE
 </dtml-comment>

 <dtml-if "_.string.find(ua,'MSIE 3.0') != -1">
  <dtml-call "REQUEST.set('bMSIE3',1)">
 </dtml-if>
 <dtml-call "REQUEST.set('iMSIE4',_.string.find(ua,'MSIE 4.0'))">
 <dtml-if "iMSIE4 == -1">
  <dtml-call "REQUEST.set('iMSIE4',_.None)">
 </dtml-if>
 <dtml-if iMSIE4>
  <dtml-call "REQUEST.set('bMSIE4',1)">
 </dtml-if>
 <dtml-if bMSIE4>
  <dtml-call "REQUEST.set('minorVer',ua[iMSIE4+8])">
  <dtml-if bMSIE4>
   <dtml-if "minorVer == 'p' or minorVer == 'b'">
    <dtml-call "REQUEST.set('bMSIE4_beta',1)">
   </dtml-if>
   <dtml-if "minorVer == '1'">
    <dtml-call "REQUEST.set('bMSIE4_01',1)">
   </dtml-if>
  </dtml-if>
 </dtml-if>
 <dtml-if "_.string.find(ua,'MSIE 5') != -1">
  <dtml-call "REQUEST.set('bMSIE5',1)">
 </dtml-if>
<dtml-else>
 <dtml-comment>
  Let's assume netscape
 </dtml-comment>
 <dtml-call "REQUEST.set('bNetscape',1)">
 <dtml-if "ua[8] >= '4'">
  <dtml-call "REQUEST.set('bNetscape_4',1)">
 <dtml-elif "ua[8] >= '3'">
  <dtml-call "REQUEST.set('bNetscape_3',1)">
 <dtml-else>
  <dtml-call "REQUEST.set('bNetscape_2',1)">
 </dtml-if>
</dtml-if>


Include this in your standard_html_header and then use the variables in your
pages as normal,so:

<dtml-if bNetscape_4>
  do netscape specific stuff
<dtml-elif bMSIE4_01>
  do IE specific stuff
</dtml-if>

Hello Olivier,

Thank you for your help. The call to the method seems ok, but the code
of the method is displayed instead of been executed. May be is it a
code for external method ? Other things to do instead copying the code
to the DTML method code window in the Zope interface ?

Anyway, could someone please post an exemple of an DTML method
accepting parameters - that is the code to put in the proper windows
in the Zope interface - or a pointer to a document explaining how to
proceed ?

Thanks in advance,
Greetings,
Eric

I don't know.  Further, I'm not sure if the fix is in the 2.1 branch. 
Possibly not, so you'll have to wait until 2.2 which has no release data
set and will probably go through a thorough beta period.

Not really.  Check out the zope site under Resources and read the
instructions on how to check out code from the CVS.  You could probably
get away with replacing your ZServer/medusa directory with the CVS
version, but don't be suprised if that doesn't work.  In fact, if you
aren't confident about that or don't know how to use cvs or don't know
python, I don't recommend you do that at all.

Message-ID: <4.2.0.58.20000316233055.0163ae70@192.168.0.2>

[Repost - previous message was truncated.]


Hello,


I've been playing with ZClasses and I ran into an issue with ZObjectManager.

Summary: (when creating a folderish ZClass and cascading base classes) if 
ZObjectManager isn't subclassed at 1st level, objects can be added to the 
folderish ZClass instances but they don't show in the manage_main object list.

[Zope 2.1.4 on Win32, pure ZClasses, no Python around]

More details:

1) I first tried this simple setup. It worked fine:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyTestClass

MyTestClass is folderish and works as expected.


2) This setup worked fine too:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyBaseClass
     |_MyTestClass1
     |_MyTestClass2

I can create a custom base class and use it in several ZClasses. They are 
folderish and work as expected.


3) Then I tried this setup:

ZClass_for_CatalogAware
ZClass_for_Renderable
   |
   |_MyBaseClass
   |_ZObjectManager
      |_MyTestClass

Here I first created MyBaseClass, then I subclassed it together with 
ZObjectManager when creating MyTestClass.

MyTestClass looked OK; I created a Content view linked to manage_main; I 
allowed adding standard object types such as Folder and File.

However, when I add objects in an instance of MyTestClass they do not show 
in the object list (Content view). I *think* they are actually added 
because I cannot add an additional one with the same ID: I get an "ID 
already in use" error.

When testing further I got the same results when CatalogAware and 
Renderable were not around. Same results too when subclassing Folder instead.

It's not that bad, but I can't create a standard base class, then use it to 
create a folderish variant.

Does anyone understand why?


Cheers.

Alexandre

Your pattern is ^/Zope/(.*).  The ^ means match the beginning of the
'script path'.  So, this pattern will match:

http://www.test.net/Zope/

Keep in mind this will NOT match http://www.test.net/Zope (without a
terminating /).  If you want to match:

http://www.test.net/

The use the pattern ^/(.*)

You many need to play with the initial /s a bit.  Various versions of
mod_rewrite have done this different ways, some versions match ^ up to
the first /, and some don't.

Do note the rewrite documentation at 
http://www.apache.org/docs/mod/mod_rewrite.html

``The great thing about mod_rewrite is it gives you all the
configurability and flexibility of Sendmail. The downside to mod_rewrite
is that it gives you all the configurability and flexibility of
Sendmail.''

Hi,

I am currently developing a new product for my company using Zope. No I am
running into a problem. I like to use the building user management and user
auth features, but I also need add to some new properties to a user record.
Nothing big just a few properties, that a relevant for some user specific
configuration parameters.

Can I add new properties to an User object, or do I have to create a new
UserFolder and new User object using ZClasses? The later wouldn't be very
satisfying. Or can I just create my own type of user and add it to any user
folder? Especially the buildin user folder of Zope?

Bye, Oliver Andrich

If you're using the 'start' script, background it:

Has anyone else seen this type of message.  We've been assuming they are

The Z SQL Methods User's Guide

This shows you everything you need to know to do things the Zope way. It assumes
you have a basic understanding of HTML forms and the SQL language.

I have gone a little bit down the road toward a design for this:

  http://www.zope.org/Members/tseaver/CosNaming

I also have some hackish code on my local box which exercises a tiny portion of
the design.  The code is too ugly to release, but I do hope to be working on it
over the next few weeks.  There are a couple of other folks on the list
interested in CORBA as well -- I'll CC them in case they have gotten further off
the dime than I have, and would therefore be able to bump your comfort factor up
a bit higher.  Perhaps we should set up another list for this topic?

There is a special piece of syntactic sugar for one-based numbering::

  <dtml-in "_.range(x)">
    <option><dtml-var sequence-number></option><br>
  </dtml-in>

(See $ZOPE_HOME/lib/python/DocumentTemplate/DT_InSV.py for more grubby details).

Subject: [Zope] External Methods and REQUEST
Message-ID: <38D1A522.E70421A6@picknowl.com.au>

Greetings,

I've started having a serious fiddle with External Methods, and have
run across a couple of brain issues:

1)  Most examples I've seen (well, both :-) pass REQUEST as a parameter
in addition to self (for example, def frobnicate(self, REQUEST)).  Yet
I've noticed that I can pull REQUEST out of self's namespace, and they
appear identical.  Is there a reason for passing in REQUEST explicitly?

2)  (And if this is related to point #1, then you may beat me around the
head with a Nerf bat).  I defined an external method called frobnicate
as follows:

def frobnicate(self):
    "One of many test functions"
    return self.REQUEST.form

and install it.  If I call it with http://localhost/zope/frobnicate?foo=bar
it returns a dictionary of {'foo' : 'bar'}, as it should.  If I call
it without any arguments as http://localhost/zope/frobnicate the
browser hangs and eventually times out with "The document contained no
data".  I'm specifically interested in form data here, which is why I
haven't used the REQUEST['thingo'] idiom, so I suspect I must be
accessing REQUEST incorrectly.  Any clues would be most welcome (if
only someone could write a ZenOfZope product; I'd download it into my
brain in an instant! :-)

Overview

I am trying to put an XML structure into a Zope product that mirrors the=
 hierarchy.

The dtd for the XML is roughly of the form
<!ELEMENT nodes (node)*>
<!ELEMENT node (node|leaf)*>
<!ELEMENT leaf (object)*>
<!ELEMENT object EMPTY> 

The 4 elements share several attributes and each has some unique=
 attributes. So the intent is to group the common attributes in a couple of=
 property pages and create an property page for each individual element.

The desired ZClass representation is as follows:

I build the hierarchy, set permissions as follows and do the factory edit=

I instantiate a container,

At this point I can only add twigs though I think I should be able to add=

Am I missing something here? I have tried countless permutations with and=

I am not sure what is going on but wouldn't it be generally safer if your
java class converts the encrypted cookie in some ASCII text format first?
I think that will solve your Zope problem too.

In general the process is:

- create a database adapter
- create a zsql method to do the insert
- create an html form to submit the data
- create a dtml method to call the zsql method as the form's submit action

Here's a pretty good how-to that describes the entire process in detail.

I find these pages to be an essential reference for zsql:

Hi Jeff.

Can you post the traceback. If this is the error I think it is then it may be
related to what you set as your SMTP server when you created the WorldPilot
object. One thing I found that works reliably is to specify   localhost  for
the SMTP and IMAP servers. 

BTW which IMAP server are you running? and what is your SMTP server?

Good Luck!

Being explicit.  Also, your method might not (depending on how you use
it) be being called from ZPublisher (in which case REQUEST is not
passed, it must be acquired), then again, your method might not be in an
acquisition context either, in which case you must pass it.  In 99% of
the cases however, you can do either.

Well, hanging is probably not the best way for Zope to handle this
situation, why it hangs I couldn't tell you (perhaps you should post
that to the collector).  However, form data usualy comes from a POST,
and here your doing a GET, passing a query string.

You can still get form data that way, the form attribute of REQUEST is
when you want to make sure you're definatly getting a value from a form
and not some other namespace.

I went ahead and wrote a Java helper class to convert from base 8 to base
10.  This has resolved the problem.  For those interested:

private static String convert(String uid)
	{
		
		StringBuffer sb = new StringBuffer();
		StringTokenizer octalString = new StringTokenizer(uid, "\\",
false);
		Integer convert = new Integer(1);

		while(octalString.hasMoreTokens())
		{
	
sb.append((char)convert.parseInt(octalString.nextToken(), 8));

		}	
		return(sb.toString());
	}

I am still curious as to why Zope converts the data into base 8.

Thanks for your response.

I keep forgetting that Zope is a collection of products :-(.  One day,
I do intend to spend more quality time with the source and how the
components interact.

Oddly, it only appears to do that when I call the external method
directly.  If I place <dtml-var "frobnicate(REQUEST)"> (modified to
pass in REQUEST explicitly) into a Method or Document and request
that without parameters, it comes up immediately and correctly.
Odd.

Will do.

Ahh, differing semantics.  I'm used to Python's cgi.py (and Perl's
cgi.pm, from memory) treating POSTs and GETs with query strings
the same.  The only way of telling the difference was by looking
at the REQUEST_METHOD (if you cared enough, that is).

This was my concern - REQUEST's namespace seems a little crowded, and I
was worried about clashing identifiers.

Hold the phone!  I've just constructed a document that basically does
<dtml-var REQUEST>, and invoked it with a query string, and the
parameters DO show up in REQUEST.form.  Are you pulling the wool over
my eyes, Michel?  :-)

Regards,
  Daryl Tester

PS - The recent "Virtual folders / URL" thread solution you proposed
was _very_ enlightening, but yet reading about direct traversal in
the ZSQL manual didn't provide anywhere near the same lightbulb factor.
Could Digital Creations consider adding that in as an example?

Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF372@ap3expr3applge.appl.ge.com>

All,

Have been trying to add File Attachment functionality to the ZDiscussions
Product.  Thus far, I have modded the ZDiscussions.py file, specifically the
ZDItem class's __init__ method, to accept one extra parameter called file.
The corresponding DTML-Method (postForm) within the ZDiscussion object has
been modded to include a FILE input field.

To facilitate the file handling, I am using the Squishfile.py module.  All
is working well, and via a new def attachment(self) method that was added to
the ZDiscussion.py module, I am able to return the file to the browser.

Herein lies the problem.  How can I reference the file via an HREF?  With
the following DTML:

<dtml-if attachment> 
	<b>Hello there</B>
	<tr><th bgcolor="#d0d0f0" align=left>Attachment:</th><td>
	<dtml-in attachment>		
		<A HREF="./<dtml-var file_name url_quote>">  
		<IMG SRC="<dtml-var SCRIPT_NAME >/<dtml-var icon >"
HEIGHT=16  
		  WIDTH=16 BORDER="0" ALT="Click to download
attachment"></A>    
		<A HREF="./<dtml-var file_name url_quote>">  
		<dtml-var file_name></A>   
		<dtml-var file_kbytes>KB (<dtml-var file_bytes> bytes)<BR>  
	</dtml-in attachment></td>
</dtml-if>

This of course references the file object as
absolute_url/ZDItem_id/file_name.  This same reference url is used in the
Squishdot product when displaying a link the user may click on to download
the file.  However, in my implementation it is not referencing the file.

The only way to reference the file is to use <dtml-var attachment>, which
means that the file will be streamed to the user as soon as they click on
the message thread, obviously not the way I would like to handle the
situation.

Do I need to include the file object as a property of the message?  I
thought by including the file object during the creation (__init__) method
of ZDItem this would be handled.

Any/all assistance would be greatly appreciated.  Also, if I am crazy for
doing this please let me know.  Perhaps a new ZDiscussion already exists
that supports attachments?

Thanks again,
-Brian

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,

Michael Bernstein.

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,


[RH]Michael,

What you seem to be descibing is some sort of an internal Zope 'link base'
as they exist for may hypertext systems (but zopish). This would be very
useful.
I do have some doubts about your desciption, however:

- would the generic relationships (meta-type<->meta-type) you describe be
the best way to go and whether they would turn out to be very useful. You
also do not mention one-to-one relationships; I'm sure this is not on
purpose, but this could be implemented quite simply by a specific python
product.

- I also wonder whether much of what you describe cannot also be achieved in
other ways, mainly through using the Catalog (as you indicated yourself). If
I may speculate a bit more on this point: what you want may be a specialized
folder index method that uses a mix of its own objectValues and Catalog
obtained objectvalues for its contents. If you wanted to use symlink type
relations, this may be done by using properties (this is more or less
generic) or by using the values of a 'link base' type of object (see above).
THis last would be very specific: pointing to specific objects.

- The idea of relationship aware is nice, but the drawback is that it can
only be true for derived ZClasses, and not all zope objects are Zclasses.

- In ZDP list many of these subjects have been in question for some time
now. You may want to have a look at the list archives of last month for many
of the discussions and of course the implementation of ZDP Tools by Maik
Roeder (available somewhere from his member page:
http://www.zope.org/Members/roeder)

Hi,

Wasn't it generally agreed that storing a counter in a ZODB was a bad idea 'cos of the high number
of refreshes, and hence the number of transactions stored in DB?

Basically, because of the undo/rollback capability of ZODB, the data.fs grows rapidly if you use it
to do counter-type things.

Or an I wrong?

I am using Zope for an large  project at the moment. For static content, 
such as images, I use apache to server them up (and will probably move
to something faster such as thttpd or kernel mode http server) and then just store
a URL reference to the actual data. This leaves zope to do presenatation, which it
does really  well and let a more suitable server handle the static content.
Any way, I'm not saying that zope couldn't handle this however depending on
 your exact use this may be an option for you.

Cheers,

Benno

You can help yourself by consulting the archives of this mailing
list:

The solution is to patch MySQLmodule.c to make it compliant with
mysql.h of newer versions of MySQL.

You can find my (unofficial) patch in the archives of the mailing 
list at

DTML-LET is meant for renaming expressions, like a macro

      <dtml-let name="bob"
                relation="uncle">
        <dtml-var name> is your <dtml-var relation>
      </dtml-let>

what actually gets evaluated is <dtml-var "bob"> is your <dtml-var "uncle">,
which is nice.


the other part <dtml-let x=5 y=7>

is rewritten to <dtml-var 5><dtml-var 7>

which is not nice at all as there is no variables called 5 and 7.

OTOH 

      <dtml-let x="5" y="7">
        <dtml-var x><dtml-var y>
      </dtml-let>

should run fine as then x and y are expressions and not variables 
so 
<dtml-var x><dtml-var y> is <dtml-var "5"><dtml-var "7"> which runs fine.

If you want to put a string into any variable you must do it as follows:

The term inside double quote is python code and in your code, without

Subject: [Zope] security question
Message-ID: <001401bf900d$0e049860$1464a8c0@sabine>

hello:

for my zope, the root directory is protected so that anonymous users have no
permissions.  in addition to root, two other users are defined and given the
role 'internal'.  one of the users has a username/password.  the other
allows access based upon IP range.  this works as intended.

i now want to give anonymous users permission to access
/subfolder/index_html.  this dtml method accesses a database and uses
LocalFS.

my first attempt to realize this was to assign the appropriate permissions
to Anonymous for index_html.  when this failed, i went to the /subfolder
security and modified permissions there that seemed relevant.  i tried many
combinations until finally giving up and granting all available permissions
to Anonymous at the /subfolder and /subfolder/index_html levels.  so now,
all permissions are checked for 'acquire' and for 'Anonymous'.

even this does not work!  users attempting to access
http://myzope/subfolder/index_html are greeted with an authentication
dialog.

so, despite the fact that security seems to be a pretty simple concept i
seem to be missing something fundamental.

any insight would be appreciated.

thanks,
bac

Security is never a simple concept, especially in system as complex as Zope.

Some decent documentation would help ;-)

Stupid bug :-)
here is the patch against
lib/python/Products/jcNTUserFolder/NTUserFolder.py:

164a165
>         userobjects = filter(None, userobjects)


if you don't have patch.exe (which is likely to be the case, as you run Zope
on Windows...), the above patch means that you have to add the line
userobjects = filter(None, userobjects) at line 165 of the file so the code:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        return userobjects

is turned into:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        userobjects = filter(None, userobjects)
        return userobjects

You could also download the latest jcNTUserFolder-0.0.4 at
http://www.zope.org/Members/jephte/jcNTUserFolder

Remember: Zope must run as a service or the user have "act as part of the
operating system" for jcNTUserFolder to work!

Message-ID: <200003171426.JAA22832@saltmine.radix.net>

[I'm posting this again because, suprisingly, there was no response]


I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute)?

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

I would add to this that Relationship objects, or rather the unnamed
sub-objects which actually hold the data for individual pairings, should
have properties in their own right.  A relationship (especially many-to-many
type) can have information associated with it which properly belongs to
neither of the related objects, such as 'advance amount' for an Author
relationship.

It isn't clear to me that Relationships is really the right way to do this,
but if someone wanted to code it I'm sure people would try it out.

I'm guessing that Steffen is using the "default" start script, which passes the
"-D" parameter to Zope -- it is therefore running in "debug mode", and writing
error messages to the console.  Backgrounding it will work, sort of, but will
leave Zope expecting to write to the controlling tty -- if it goes away (i.e.,
Steffen logs out), then Zope will die hard when trying to write to it.

A better fix is to edit the start script and remove the "-D" from the command
line.  Without the "-D", Zope will daemonize itself, and the backgrounding won't
be needed.

Message-ID: <4.2.0.58.20000317180935.00c97e80@195.60.12.162>

I'm trying to build up some variables from more than one form which are to 
be inserted into an SQL table. THe problem is that as soon as I call the 
second form the existing FORM variables in the REQUEST are lost. I've tried 
saving them in a SESSION variable using SQL Session (I can save them OK) 
but then of course I have to get them back into something which an SQL 
Method can understand. I'm stuck at this point.

Is there any way to pass the SESSION variable into an SQL Method ??

Or, if not, How do I get the values back from SESSION so that I can call an 
SQL Method ?

Many thanks in advance

No, it is not supposed to be in the list. Zope is not SSI, nor does it try
to be SSI compatable. Zope does have analogous variables, though. For
example, when I navigate to http://my.server.com/jeff/dumpRequest, I get:

  URL0 = http://my.server.com/jeff/dumpRequest
  URL1 = http://my.server.com/jeff
  URL2 = http://my.server.com

  BASE0 = http://my.server.com
  BASE1 = http://my.server.com
  BASE2 = http://my.server.com/jeff
  BASE3 = http://my.server.com/jeff/dumpRequest

  PATH_INFO = /jeff/dumpRequest
  PATH_TRANSLATED = /jeff/dumpRequest

Since I haven't done much with SSI in the past, I don't know which one is
similiar to REQUEST_URI. If I had to guess, I would say PATH_INFO is the
one you are looking for.

Try this:

<A
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80&dtml-PATH_INFO;;weblint">Link
Text</A>

or,

<A href="http://validator.w3.org/check?uri=&dtml-URL0;;weblint">Link
Text</A>

Obviously, the second is preferred, since it is both more clear and
requires less maintenance (the URL is not hardcoded, so if your server
changes from dnrdb.cbi.tamucc.edu to newserver.cbi.tamucc.edu, the code
would not require change.)

Yes.

Well, that question can't really be answered.  First off, there is a
global python interpreter lock.  I don't really want to get into the
details here, but basicly only one thread of execution can be in the
interpreter at once.  This is a pretty major limitation in Python's most
popular implementation, CPython (which is what Zope is based on).

The interpreter will 'give up the lock' every N bytecodes or so, there
is some mechanism for you to control this.  Check the python site for
more details.

Your idea is not bad, as long as you use a Storage that is multi-process
safe like ZEO.  I'm not sure if having as many Zope instances as Apache
instances is necessarily a good idea, since Zope instances can become
huge, many times bigger than their Apache counterparts.  Given Apache's
nature to do lots of forking and pre-forking (yes, this can be
controlled) this might lead to immense memory requirements.

Besides the AUTHORIZED_USER field in the http header what else does zope use to identify
an http packet from a browser ?.  I am just wondering can I not masquerade as a user by setting 
the http header using httplib or some such utility ?. I have not seen any session ids in the REQUEST
variable which is supposed to contain all the variables in the browser request

Values like this that you are looking for come from the front end web
server.  Most web servers pass a number of these variables into the
environment of a program that they are executing (in this case, Zope). 
The specification of what variables gets passed and how is called Common
Gateway Interface (CGI).

REQUEST_URI is not part of the CGI/1.1 (the most recent) spec.  I
suspect you are used to programming in some sort of SSI environment
where REQUEST_URI exists as a convienience for programmers.  I do
believe I recall REQUEST_URI being a variable in Apache.  This
convienience does not exist for Zope because it is not a standard CGI
variable and Apache does not pass it to Zope or any other CGI program. 
There is, in fact, probably some other standard variable that does the
exact same thing as REQUEST_URI.

The list of standard variable can be found at:

Subject: [Zope] Odd AttributeError (__call__)
Message-ID: <38D294FE.357B2DA4@harlan.frohwitter.com>

I have three instances of Zope running on three different machines (all
dual PPro).  On the first two machines, a simple <a
href="otherfolder">Click here to move to the other folder</a> works just
fine to hyperlink to the index_html in the "otherfolder" folder. 
However, on the third machine (ironically the one that I want to deploy
to) the same hyperlink encounters the following error:


           
           Zope Error

           Zope has encountered an error while publishing this resource. 

           Error Type: AttributeError
           Error Value: __call__



In all three instances, the security is set up the same way on all
documents, images, and folders accessed.  Incidentally, the deploy
server and one of the working ones are running Zope 2.1.4.  The other
working one is running 2.1.3.  Does anyone have an idea what my problem
is?

Thanks in advance,

Ron

AUTHENTICATED_USER is an object created after a client authenticates, it
is not an http header nor is it derived from the Authentication header. 
The Authentication header contains a user id and base64 encoded password
that is used to authenticate the client.

I assume by 'packet' you mean request.  HTTP is stream based.

No.  You can authenticate yourself with such a client, but you must
still have a valid password.  You cannot just insert any old user id
into the Authentication header and expect Zope to believe you.  That
wouldn't exactly be very good security.

Message-ID: <613145F79272D211914B0020AFF6401914DE7D@gandalf.digicool.com>

Hi all,

Zope 2.1.5 has been released - you can download it from
the usual place on Zope.org:

http://www.zope.org/Products/Zope/2.1.5/


This release fixes two fairly important security issues 
that have recently come to our attention:

  o It was possible for a Zope user with a fair amount of Zope 
    zen and permission to create DTML documents and Folders
    to circumvent the security machinery within DTML in certain 
    situations, possibly giving the user the ability to use 
    resources that he wouldn't otherwise be able to access via 
    DTML.

  o It also came to our attention that the DTML code in 
    ZSQLMethod objects was not subject to the same security
    constraints as the DTML code in DTMLMethods and DTML 
    Documents.

The 2.1.5 release fixes both of these issues and we highly 
recommend that you upgrade, especially if you use Zope for 
sites that allow untrusted users to create Folders and DTML 
Documents or DTML Methods.

The release also includes a number of recent bug fixes, 
including the problem in TimeStamp objects that caused 
the bobobase_modification_time() of Zope objects to 
appear to be a day behind. Note that this release contains
two binary changes, so those running Zope from the source 
release will need to rebuild the Zope extensions after 
applying the update. The fixes are also available in CVS 
and binaries will need to be rebuilt after the update for 
those of you using CVS.

Note that with the 2.1.5 release we will also be releasing
"diff" updates as .tgz files that will let you easily 
upgrade an existing 2.1.x site. These updates are available 
for those currently using the 2.1.x source release or the
2.1.x binary releases for either solaris or linux (diff 
releases are not available for win32 for now).

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

As far as authorization goes, I've noticed that I get prompted for a
user-name/password only once during a session.  After you've been validated, it
appears zope does not prompt you again for that browser session.

The reason I'm concerned is that if I have to do maintenance on someone else's
web browser, how do I ensure that after I leave a person cannot use the back
button or history list to gain manager access to the site?  Do I have to exit
the browser when I'm done?

Daniel,

THis is a limitation of HTTP basic authentication and is not a
Zope-specific problem.

Either quit the browser before you leave or write a short dtml method:

<dtml-raise Unauthorized>
Logout
</dtml-raise>

and call it before you leave.  Note that you need to call it, then click
"OK", or you will still be logged in.

Actually Zope does prompt your client on every single request (that
requires authorization), it must, because HTTP is stateless.  Zope also
validates every single request.

This is a 'feature' of the HTTP Basic Authentication spec that says
browsers can cache auth information.  It is however often a lack that
browsers do not let you manually clear this cache.

Yes.  Or force the client to discard it's cached auth info with a
<dtml-raise Unauthorized></dtml-raise>.

Yes, you can nest dtml-in's and you pass the parameters to the SQL
method by explicitly invoking it as an expression, not just as a
name.  (It happens that I asked a very similar question of this list
recently, which is why I now know the answers.)  My example, stripped
down a bit, looks like

<dtml-var standard_html_header>
<dtml-in search_author size=50 start=query_start>
  ...
        <tr>
          <td class="center"><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
          <td><dtml-in expr="return_authors(seq=seq)">
                  <dtml-var name>;
              </dtml-in></td>
        </tr>
 ...
</dtml-in>

I hope this is enough to get you started.  Contact me directly if you
would like more explanation.

Yes. Assuming that you're using basic HTTP authentication, restarting the
browser will clear everything out.

The key to figuring this behavior out is understanding how ZPublisher maps
a URL:

 * Split the URI path into a sequence of names

 * From the root, traverse each named object in order (allowing
   it to intercept the traversal, if it wants).  Traversal requires at
   least minimal permissions on the traversed-through object.

 * During traversal, allow the acquisition machinery to operate

 * If the last item traversed to is callable, call it;  otherwise, render
   it.

This works somewhat like permissions on a Unix directory:  you have to have the
executable bit set in order to traverse the directory, and the read bit set in
order to list it.

Hope this helps!

 Thanks.  I would think then this password is succeptible to the same pitfalls
as  sending clear text passwords over  the network which can be stolen. In
which case making users to use https is a good idea ?

Yeah this is probably the best idea. Zope sits
quite nicely behind apache-ssl

Message-ID: <Pine.LNX.4.10.10003172246500.10594-100000@yoni.northernwastes.org>

So...

I'm sure the answer to this question is painfully obvious, but I've
pounded on the docs and I can't find it for the life of me.

I have created a subclass as per the instuctions in the Zope Developers
Guide.  I am doing this specificly to avoid my inner class polluting the
global product list.  (There will ulimately be a large number of these
inner classes if I can figure this out.)

So far, so good.  Using the dtml-var tag I can display any property of any
instance of my newly created subclass.  But I also need to build a table
that iterates though all instances of this subclass and displays several
of it's properties.

I suspect this involves the use of the dtml-in tag, but I can't for the
life of me figure out what the syntax should look like.  The discussion of
dtml-in tag seems to imply a list of objects in a folder, and what I have
is a list of subobjects in an object.

Hints anyone?  How-To?  FAQ?


TIA,


Geoffrey L. Wright

When Zen borders on Kamikaze.....

DTML Document --> product method --> DTML method

I've been banging my head against this for 4 days in a row now. I want 
to call a DTML method, via a product method, from a DTML document, but
I don't succeed in setting the client namespace for the DTML method to 
the original DTML Document's namespace.

I'd appreciate any help!

I have a DTML document. It has a valid aq_parent. From this DTML document, 
I'm calling a product method, passing the DTML documents's aq_parent as
an argument:

<dtml-var "NFGnavCore.aqqy(aq_parent)">

This method has access to the aq_parent object all right, tested
OK. Next, the DTML method is called from the product python method and
the original aq_parent object is given as the new acquisition context:

	def aqqy(self, context=None):
		""" some test method"""
		retval= "Hi! I'm the aqqy method, called with context.id <b>%s</b>" % context.id
		return retval + self.aqqy_helper(client=context)

The DTML method 'aqqy_helper' is called all right, but has no access
to the context object passed in. Any attempt to access objects that
should be in the acquired namespace, for example:

		 My aq_parent id= <dtml-var "aq_parent.id">

results in an error message:

          You are not authorized to access aq_parent. 

Which, if I'm not mistaken, is caused by the validate routine called 
from OFS/DTMLMethod.py as documented in 'oldvalidate()':

        if inst is parent:
            raise 'Unauthorized', (
                'You are not authorized to access <em>%s</em>.' % name)

So what am I doing wrong, and what is the right way to call DTML
methods from product methods?

Well, this gives you the ability to create, for example, 'Car' and
'Bicycle' objects, and designate them both as meta type 'vehicle', then
create an 'Owner' relationship between 'vehicle's and 'Person's. A
trivial example, to be sure.

I suppose the relationship objects could be 'instrumented' to allow
other types of filtering criteria. Whatever the criteria though, the
possible objects need to be presented through a 'relationships' form
within the ZClass instance.

You're right, one-to-one relationships should be implemented as well,
but as you noted, this proposal is not as critical to implementing
one-to-one relationships as it is for many-to-many.

That's pretty close. My proposal actually has two levels of indirection:
first the relationship objects that are relevant to the ZClass are
obtained from a ZCatalog like object (the relationship folder in the
control panel), and then those relationship objects (themselves
ZCatalog-like) are queried to obtain the objects that the ZClass
instance is associated with. Then you should be able to access these
objects' properties and contents as if they were contained within the
current object's relationship:

<dtml-in Author>
<dtml-var name>
</dtml-in>

By doing it this way, you can add relationship types between you classes
as your application grows in complexity without having to re-instantiate
all your objects. All you would have to change would be the add/edit
methods in the ZClass, and whatever viewing methods that you want to
expose the new information (other than the relationships tab in the
management intrface).

Neither approach would give me the ability to refer to linked to objects
as if they were sub-objects. This is critical for the simplicity of the
DTML to access the associated objects' contents and properties. In
short, I want a pseudo sub-object that acts as a proxy for the real
object, not a symlink I can follow or resolve to access. The end result
is much the same, but the semantics are radically simpler with my
proposal. Note: associated objects should NOT appear within the
'Contents' tab.

First, relationship_aware is optional; all it's absence means is that
the object is not aware of it's outgoing relationships. Other
relationship_aware objects could refer to it with no problem. Second,
if, for example,  you want a relationship_aware Folder, just subclass
Folder and relationship_aware in a new ZCLass.

Zope doesn't know how to call or execute php code.  To do this, you need
to have Zope make an 'external' http call back out to Apache, which will
execute the php code, return it to Zope, which returns it to your
client.

Here is a good how-to on it:

Hmm. This update has broken all my zsqlmethods I've tested so far.  I've
reverting to 2.1.4.

Eg when testing from the management interface:

File D:\zope2\lib\python\Shared\DC\ZRDB\DA.py, line 459, in __call__
    (Object: sqlShowComment)
TypeError: too many arguments; expected 4, got 5

SQLSESSION has also died with this version release.

I couldn't find 2.1.4 on zope.org, but had a copy of 2.1.3, and that has

Hi everyone,

I'm using Amos's RSSChannel prodcut along with XMLDocument, but it seems
that upgrading to 2.1.5 has broken it. Can anyone else verify this?

Can you describe how it is broken?  Is there a traceback?  Are both
RSSChannel and XMLDocument broken?

Notice that line where it refers to RSSChannel.py. It's pointing to the
RSSChannel.py file in my previous (2.1.4) version of Zope. Odd.

However, it might have something to do with the fact that when I installed
2.1.5 I didn't untar a fresh copy of RSSChannel, but copied it to the new
directory instead. I did that because I'd made some changes to
RSSChannel.py and another file and didn't want to redo them. I did a 'cp
-a' if memory serves.

I was under the impression that you could copy the directories in
lib/python/Products/ over to a new Zope. Obviously it didn't work in this
case.

I think integer division was covered last week on this
mailing list.  Change 1/24 to 1.0/24 (the upshot is 1/24 is
evaluating to 0).

As far as I can see, I'm not getting any errors about missing includes

Fabrice,

I ran into similar errors.  Here's the response from Jo Meder that helped me
get MySQLDA compiled:

I suppose line 1125 of mySQLmodule.c is something like:

	tf = & (mysql_fetch_field_direct(self->res,j));

If this is the case, try applying the following patch to your
MySQLmodule.c (this is strictly "works for me"):

------------------cut here-----------------------------------------
235c235
<     unsigned int *lengths;

Subject: [Zope] Looking up object instances in a folder
Message-ID: <38D4C514.ED1D3EB5@funcom.com>

I have some instances of my own ZClass in a folder, and I can iterate
over them using:

<dtml-in "somefolder.subfolder.objectValues()">
  <dtml-var title>
</dtml>

The instances are stored using auto generated ids (simple numbers).

In addition to being able to iterate over the instances in the folder, I
also need to access an instance directly by using its id which is passed
in the REQUEST object, but so far I have been unsuccessful. What I am
trying to do is something like:

<dtml-in "somefolder.subfolder.getInstance(REQUEST.id)">
  <dtml-var title>
</dtml-in>

but I have not been able to get access to just the one instance (but
iterating works fine as mentioned before). Could somebody with a clue
give me a hint?

Thanks in advance,

   The ZMySQLDA is used (and will be used) by so many people that this
information should be packed into a HOW-TO and published along with the
very DA.

Subject: [Zope] Find object in a directory question
Message-ID: <20000319141420.A2559@mimar.demon.nl>

Hi,

I've created a ZClass 'CLink', which contains a URL, title and such things.
In my dtml-pages, I can do <dtml-var slashdot>, and the slashdot-clink
object will insert the <a href=...></a> stuff for me. I've got this 
working using the Renderable class. 

I've planned to put all CLink objects in the /links folder so I can
automatically create 'bookmarks' out of the links I reference to. I also
want to be able to categorize the links into subfolders, so I want to have
a links.sports.ski.resorts directory with ski resorts, and a
links.news.nerdish folder for nerd-related news. 
I can use <dtml-var links.news.nerdish.slashdot> to refer to the slashdot
object that way. 

However, I want to easily change my categories, without changing all
<dtml-var ...> that reference object in the categories. So I figured, I'd
make it <dtml-var links.find('slashdot')>. This should one day be the same as
<dtml-var links.news.slashdot> and the next day the same as
<dtml-var links.news.nerdish.slashdot>. With my external method (which only
looks in the current folder so far), I can't get this to work. 

Any ideas? Would the same be easier or simpler using a ZCatalog? 
Refering to a link should not be too much typing. 

As an extra question: is it possible to refer to an object in multiple
places, like softlinks (or hardlinks) in unix? Suppose I have a folder with
'My Frequent internet-visits', and 'News', they could both contain the same
CLink. Is that possible in zope?

Well, hope I made anysense..
Thanks,
    Chris Niekel

   It seems on one of my computers the problem went away whe I tried to
hunt :) - Zope 2.1.3 + SiteAccess 1.0.0 on Sun Sparc Solaris 2.5.1. I'll
test linux installations later.
   I have problems upgrading to 2.1.5 - initially Zope came up well, but
when I tried to install 3rd-party modules (including SiteAccess) - I could
not login. I didn't traced the problem to SiteAccess or other product yet...

Hello!

   Five minutes experiment - and the problem is narrowed down to
SiteAccess. Clean and fresh install of Zope 2.1.5, than some 3rd-party
modules - Zope came up well. install SiteAccess - and I cannot login to
Zope. Authentication failed all the time. Seems SiteAccess became
incompatible with latest Zope. Go back to 2.1.3, waiting for new Zopes
and/or new SiteAccess' :)

Subject: [Zope] Public available DTML Source of zope.org?????
Message-ID: <20000319163904.C28541@owl.rhein-zeitung.de>

Hi,

may be some people might remeber my question concerning the user folder
question. Well, I haven't got any answer yet. But I found a source a knowledge
that would give me all the information. Basically I don't need much more then
the register DTML method of zope.org. Is the DTML source for the user
registration and user updates available for download somewhere? When I hit the
view "DTML Source" link I get a "Not Found" error. Everything else on Zope.org
can be inspected this way, but why not these pages? This can't be such a
security problem at all. Or am I just to dumb to discover the trick.

Thanks for any hint.

Best regards,

    Oliver Andrich

   These pages probably written in Python, hence there is no view_source
for them.

Subject: [Zope] Property Sheet access from Python Products
Message-ID: <200003191153560734.0E5EF386@iqtinc.com>

I am creating a product in Python and I want to use property sheets. I am able to add sheets and add properties to those sheets. However how I have to access the property sheets differently than if I was accessing property sheets on a ZClass programmatically. I suspect that I am perhaps not using the right mixin classes.

For instance, I have a property sheet 'Private' with an attribute 'prop1'
If I create this in a ZClass, I can use 
<dtml-var prop1> to access my attribute.
in my class I have to do the following
<dtml-var "propertysheets.get('Private').getProperty('prop1')"><p>

likewise in Python code I must access the attribute using 
self.propertysheets.get('Private').getProperty('prop1')
where in a ZClass I could do 
propertysheets.Private.prop1

My class declaration is as follows mixins:
class base(ObjectManager,PropertyManager, 
    Acquisition.Implicit,
    Persistence.Persistent,
    RoleManager):

Am I missing a mixin somewhere? Or do I have to access the attributes differently from a Python Class?

Thanks 
Bob

Could you give us some more detail?

First of all, and this was probably just a typo on your part, but the two
products will appear in the "Available Objects selection list", not in an
"External Methods" list.

If they don't appear there (after restarting Zope), go to the Control Panel
and click on Product Management at the bottom of the page. If the installs
of Squishdot and TinyTables are busted you'll see them listed as such on
this Product Management page. Click on each broken item and send what it
presents you with to this list. Someone will be able to help with it at that
point. What I've just described is the procedure for debugging a failed
Squishdot install per it's installation instructions.

And you do see a folder for each of these products in your
zope/lib/python/products dir, right?

Hello all,

I think I have Zope running. I can get to the localhost:8080/manage page
and go into the Control Panel and External Methods.  I've tried to
install TinyTable and Squishdot by untarring them in /var/zope with
subdirectories preserved. No go -- they don't seem to show up in
External Methods as they say they should by the Squishdot Install guide.
Can anyone help?

Ahh, thank you. The Squishdot documentation is quite non-specific and says
you'll find it in Available Options.  The first Available Options I found was
under External. I see them now and have created a Squishdot site selecting the
demo.  Not sure how to get to the first page of the demo which I've put at
localhost.  Can you tell I'm new? -- IV

Learning Python is a great book if your new.  I had a chance to look at
Python Essential Reference before it went to print and it is also an
excellent book and well thought out reference.

I saw the same problem under 2.1.2.  What was even odder, I deleted my
equivalent of NewTestVersion, and recreated it.  After entering the
version, my browser still said 'working in TestVersion'.  Restarting
the browser fixed that, so it must have been some sort of caching

Subject: [Zope] reall-time data to a Java client interface from ZOPE
Message-ID: <003601bf91e9$0c1d5680$265eb5cf@kevin>

I've built an application with ZOPE and would like to create a Java
interface to it (probably using jpython/wxWindows)

Here's how it should work:

When changes are made on the ZOPE site by a client, a notification is sent
from ZOPE to the Java interface and displayed in real-time. The idea here is
not to have a continually refreshing Java window, but a window which updates
only when it receives a message from the site to do so.

What I don't know is how to send the data from ZOPE to the Java client.  Can
anyone point me to any existing ZOPE Products/Projects/How-To's which are
similar to what I've described, or perhaps point me in the right direction?

You could always put the values you've already accumulated into

This is because Zope has challenged for a username/password, and KFM doesn't
handle that nicely.

Either put http://user:password@localhost:8080/manage (iirc - there is a HOWTO
about this) or use a more sophisticated browser, like Netscape (but beware the
memory leaks when editing textareas. ):

David,

In order to use the management screens, you need to use a browser that
supports HTTP basic authentication.  To my knowledge, KFM does not
support this.  Use Netscape or Mozilla.

Hmmm.  Tried that, but still no luck.  Zope give me a
NameError, and tells me method is trying to reference a
nonexistent variable (fullname).  Here's the current
draft of my code:

<table>
  <tr>
    <th>Name</th>
    <th>Description</th>
  </tr>
  <dtml-with bwlib_abilities>
    <dtml-in "fullname('AbilityClass')">
      <tr>
        <td><dtml-var fullname></td>
        <td><dtml-var description></td>
      </tr>
    </dtml-in>
  </dtml-with>
</table>

Where bwlib_abilities is the name my container class,
AbilityClass is the subclass in question, fullname is
the sorting criterea and a poperty of AbilityClass, and
description is also a property of that subclass.

I know I'm hanging on something silly here, but I can't
for the life of myself figure out what it might be.

Also (as a more general sort of question):

Is this way of organizing data (ie, a bunch 'o
subclasses in a container class) a reasonable way to
deal with lists (50 to 100 items) of quasi-dynamic
objects?  I'm from more of a more traditional database
background, and am used to putting this sort of info in
a table.  But in the case of this particular app, ZODB
seems idea since it provides several less technical
users of the app a ready-made interface to these objects
and I don't really need access to this data outside of
this single app.  But there seems like an almost
daunting amount of flexibility in the way I might
organize this data -- objects in folders, subobjects in
container objects, zcatalogs, etc.

Thanks,

That behavior is expected. As far as I remeber, KFM (in the 1.x versions) 
does not support HTTP authentication. 
Furthermore, 
http://localhost:8080/manage?__ac_user=superuser&__ac_password=PASSWORD did 
not work for me either.

I don't know how KDE 2.0' new konquerer will handle it. But as much as they 
worked on this application, it will work there. Can anyone confirm that?

Stephan

sha is an optional python module.  Presumably it wasn't included
in Modules/Setup when you compiled your python, or wasn't included in
the binary set if you got a binary distrabution.  (It should
be a dynamically loaded module).

The module is used if you request sha encryption on the password.
If you choose some other encryption type the sha routines won't
get called.  So as a quick fix you could remove the sha from
the import line.  But you probably really want to recompile python
to make sure that all modules Zope uses are included.  Hopefully
there's a list somewhere, though I can't recally seeing one...I just
enabled all the modules I could <grin>.

Message-ID: <Pine.BSI.3.96.1000319220658.3933H-100000@twirl.bitdance.com>

There was a recent mention of using Lynx to access the management
interface of Zope.  I'd like to use w3m.  It produces a more pleasing
page given all those little spacer images Zope uses.  Also, it
automatically launches vi for me when I hit return on the edit
screen's text input area, which is *way* cool <grin>.

However, it doesn't seem to be handling the management interface
correctly.  If I descend into a management link, I get the 'view'
panel for the link instead of the manage_main screen.  Worse,
I tried to 'rename' an index_html method, and it renamed the
index_html in the *parent* folder!  This is most weird.  Anyone
know what Zope could be emitting that w3m is not handling correctly?
I'd guess redirects, but I'm surprised I end up in the view screen
in that case...

I'm currently running w3m beta-991203.  Anyone know if whatever-it-is
is fixed in a later version, assuming there is one?

This is w3m's fault, it does not send the Authentication header to
frames in a frameset, just to the frameset.  Zope calculates
'manage_workspace' based on various factors, including whether or not
you are authorized to access the managment view.  Since you are
effectivly 'anonymous' in the frame it shows you the anonymous view. 
Uncheck 'View' for anonymous and you will probably get a 401
Unauthorized.

I don't think it's Zope's fault.  In this case, w3m is probably ignoring
or not understanding the <base> tag.

You are either not using the right python, or you are using an old
python.  Python 1.5.2, including the python that comes with Zope,  comes
standard with the sha module.

It's now a standard module as of 1.5.2.  I presume matt is using an old
python or turned off sha.

i got the setup running on rh6.1, running userdb (cookie auth) for
authentication, run start as root.  i've chmod -R nobody.nobody * in Zope.  i
copied my previous Data.fs to replace the Data.fs that comes with
Zope-2.1.5-src.  will this be the cause?  i've been upgrading this way since
2.1.0
i did run with -D, but saw no error.

I knew it was all w3m's fault, since it all works in other browsers <grin>.

Thanks for letting me know what the likely problems are.  Whether or
not I'll have time to do anything with the information remains to be
seen.  I wonder, though...I'm starting from the manage_main URL,
not the manage URL, so the page I'm starting from doesn't have
a frameset as far as I can see.  Descending into a folder works,
but descending into, say, a DTML_method gets me the view.  Well,
I'll have to just ignore the whole thing for now.  w3m is a nice
browser, I hope they get these bugs worked out soon.

I do still find w3m useful, though.  Since it's U command to go
to a new URL does accept relative specifications, it's pretty
easy to use that to descend into the 'manage_main' view of
the items I'm interested in.

I can confirm this, SiteAccess broke my 2.1.5 installation.  Oleg, if

Zopistas and MikeP,

I'm trying to use etcUserFolder, and I want it to actually authenticate
off of /etc/shadow. saying /etc/shadow as the Password File doesn't
work, presumably because Zope is running as nobody.  Is there any way I
can let just etcUserFolder run as shadow?

On a similar note, am I doing something terribly stupid/compromising
here?

You can just use File objects to store the flash content, and refer to the 
objects from HTML the same way you would from a static HTML site.

I wrote a special Python object for it, inheriting from File, just so it 
would take care of its own HTML tag, just like the Image object does. 
This because the site in question contained quite a lot of different Flash 
objects, and the widths and heights changed sometimes during the course of 
the design. The designers just had to upload their flash content into these  objects, which they very quickly got the hang of.

However, for the one Shockwave game in the site, I just had the Shickwave developer upload to a File object, and the HTML for it was handcoded into the reffering HTML page.

No, that is the best way. Note that you don't have to give that user a password, and that for users from the specified set of IP addresses the authentication will be transparent.

when I was cataloging my zope site and was editing i did get a conflict
'competing' writes, which reminded me: how many times does ZOPE try to write
to the ZODB and then 'fails' and roll's back - is it 3? assuming this size
is configurable where would I go and change this?  when i was cataloging i
got this:

competing writes. could someone explain what this \xxx\yyy\zzz is?

and how do I redirect ZServer's console to a file?  I'm in DOS right now
(havent done this in awhile) - and tried to "C:\Program

that didnt work..  In linux I've tried redirectings stderr and stdout to a

I believe that is python's octal representation of an internal object
index.  The 'could not load state' means the ZODB tried to load
the object from disk storage and could not complete the operation.

I'm getting those on my own database and haven't yet had the time
to track down where they are coming from.  I fear some sort of
database corruption, but so far the system has continued to function
despite these errors.

And I can't get it to work at all.  etcUserFolder.py says to put a file
in a directory called etcUsers in the root zope folder.  OK, I made a
folder zope/etcUsers/, and copied my /etc/shadow to there.  Then I
edited it to just have a few names:passwords.  then I chowned nobody. 
This wasn't working.  I copied it to the directory of the product-
lib/python/Products/etcUserFolder.
No juice.  while from crypt import crypt worked on the command line, I
still copied cryptmodule.so to my zope directory.  No dice.  So I copied
it to etc's directory.  No juice.

etcUserFolder still tells me there are no users whatsoever. what am I
doing wrong?

Yeh, and now that ZSQLMethods don't work neither does GUF with MySQL - e.g.,
the following code fails:

  <dtml-in "sqlGetUserRoles(username=username)">
  <dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'].rolename)">
  </dtml-in>
  <dtml-return ret>

With the error message:

  "You are not authorised to access 'rolename'"

The method has a Proxy role with appropriate access to the MySQL method.  It
just doesn't seem able to access the results variable!?

   Thanks! But I have it, and I didn't remove 2.1.3 directories while

I'm getting the same error on Zope 2.1.5. My zclass A which inherits object
manager. Inside it I have zclass B. When I try to create B object inside A
folder Zope gives me an Attribute Error: _getOb inside
B.createInObjectManager ()
It seems then Zope does not see class A's parent object manager. But, I have
exported A objects containing B object from 2.1.4 to 2.1.5 and that works.

There are no problems on 2.1.4. Classes are first defined on 2.1.4 an then
exported to 2.1.5.

Zope is built from source on RH 6.0, python 1.5.2

Message-ID: <20000320100802.14614.qmail@web4001.mail.yahoo.com>

Hi,

  I've tried to write one generic SQL method and
passing argument to my SQL method using dtml-let but I
got KeyError. I've tried it with dtml-with also but
same thing. 

In my page I use:

<dtml-let curpage=total>
  <dtml-call hitinsert>
</dtml-let>

and MySQL method is:

update zp_stat 
set <dtml-var curpage>  = <dtml-var curpage> + 1

What I want to do, is passing mySQL argument and 
using one method. Ex:

<dtml-let curpage=astro>
	<dtml-call hitinsert>
</dtml-let>

total and astro are INT in my SQL table.

I dont know if dtml-let is a right way?

Any suggestion to do this?

Thank's

You can't, unless Zope runs as root (which would be a very bad thing).
This is by design.

The best you can do is:
    1) Setup Zope to run as its own user (eg. user 'zope') instead of
       user 'nobody'
    2) Add a crontab job to copy the /etc/shadow file to where Zope
       can see it, changing ownership to user zope and removing group
       and other permissions.

If you run Zope as the nobody user, then the encrypted passwords will
need to be visible to this user, as well as any other processes that
run as user nobody which is not a good thing.

Message-ID: <4.2.0.58.20000320110253.00a07c50@192.168.0.2>

Hello,


I upgraded to Zope 2.1.5 (Win 32) Saturday and carried out changes in the 
database (eg. created new ZClasses, added ZClass instances, etc.)

I had a nasty system crash (Win 95) around midnight Saturday. When I 
reopened Zope I realised the database was back to its 16:22 status:
- All new objects had vanished.
- The last transaction logged in the Undo list is dated about 16:22.
- The very Data.fs in the filesystem is stamped 16:22 if you can believe it.

I checked the Z2.log and it shows these missing changes. So I didn't dreamt 
doing them.

I suppose these changes are lost?


Cheers.

This makes the shadow password suite worthless.
Assuming readonly access to /etc/shadow it's better to use a simple 
wrapper program that can do the access. This program should be carefully 
designed to not allow arbitrary input to compromise security.

One example is checkpassword (not for non-root programs) which is located 
at http://cr.yp.to/checkpwd.html
It's designed primarily to get a simple interface to various 
authentication schemes, but my be used as an example.

Subject: [Zope] Fwd: How do I set properties from DTML? (Repost)
Message-ID: <00031617304502.13146@promotor>

I'm reposting due to mail problems of my provider ...

I'm working on a thing I'll probably call "ZBox"; it's a "widget
method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Hi! 

I thought I'd forward this to the list in case it helps anyone else:

If you want to use FTP with SiteAccess then you'll need to add the following to SiteRoot.py, after
line 124 (at the end of the SiteRoot class), and at a similar place in AccessRule.py:

    def get_size(self):
        '''Make FTP happy'''
        return 0

If anyone knows WHY this makes it work, please let us all know! :-)

cheers,

Chris

Read the documentation at www.zope.org. I think the best is to start with 
the feature tour and then "Zope Content Manager's Guide".

Is this really what you want to do?  Under this scheme, user 1 views the
site, clicks on the maxamize box, and gets the rerendered page.  Now
user 2 visits the site, and sees the maximized box.  He doesn't want
that one, so he minimizes the box.  Now user 1 clicks to maximize some
other box, and suddenly his previously maximized box is minimized.

Or am I missing something about your design?

In any case, changing properties in this way to store state is going to
cause your ZODB to grow quickly as each property state change is stored
as a new, undoable, transaction.

It seems to me you want to use either some sort of Session product to
retain the state, or do what I suspect the tree product does and
put the state you need to set/save into the URL using argument
passing ("?xxx=yyy") or by using forms to submit the change requests
and storing the state in 'hidden' fields in the frorm.

Your need a list of the AbilityClass instances in 'bwlib_abilities',
which you can sort by fullname. Assuming 'AbilityClass' is the meta-type
of your subclass, try something like the following: 

<dtml-with bwlib_abilities>
     <dtml-in "objectValues('AbilityClass')" sort=fullname>
       <tr>
         <td><dtml-var fullname></td>
         <td><dtml-var description></td>
      </tr>
     </dtml-in>
</dtml-with>

Subject: [Zope] mimetools -- an example, I hope this helps
Message-ID: <H0001bac0796f0b3@MHS>

I had to play around to get mime stuff to work right.  I needed to email
messages to about 1500 people.  Every person reaceived a couple of documents
that were the same, and each person received one document that was unique for
that individual.  I also through in a timer loop to provide a one minute delay
between each email message.  (Our mail server could not handle the load.)  I am
enclosing the code that worked for me.  Of course ymmv :)


pull_contacts : this is an sql method which pulls user information out of an
Access database.  Most of the variables listed come out of this database.

dtml-log : I used the logger product to create some logs so that I could see
that my mail messages went out.  I don't think this worked the way I wanted it
to work.

mime tag :  I added some custom code to the mime stuff because the mime stuff
does not add the mime version 1.0 header.  This may not cause problems for
everyone else, but it does cause problems for HP OpenMail and Lotus Notes.  I
do not know if anyone has fixed this in the standard zope code, but it was not
working when I did this mailout.

"_[QUESTION].data" :  this was what I had to do to pull in the unique object
for each individual.  (I imported all of my documents into the zodb.)

that makes sense.

ok, this i don't get.  i'd have thought that since i opened
what i thought was my own instance of a Zope DB, using my own
FileStorage pointing to a file in /tmp:

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/foo.fs' ) )
	connection = db.open()
	root = connection.root()

that this would have nothing to do with the DB that Zope
was using for its internals.  all of the code examples i've
seen for ZODB are from python programs, and all include code like this.
if this *is* using Zope's internal DB instance, then that would imply 
that you can't use ZODB outside of Zope when Zope is running.
what am i missing?

> (why you are getting the

it appears that was unrelated.  i actually got my example to
work since posting.  the "unable to access" thing only happens
when i get an exception due to bugs in my code.

cool.  that's good to know.

indeed.  that's part of why i wanted to use a completely separate
database.  the other part is so i can use the same routines outside
of Zope, perhaps at the same time.

i'll try that.  thanks for your help.

thanks, i'll give that a try.  i don't really need a counter, at all.
it was just a minimal example to try and figure out ZODB.

That's very odd. I tried reproducing this and couldn't.

What do you mean by parent?  Presumably, A subclasses ObjectManager.
Right?

That's because export/import doesn't use createInObjectManager.
 
I suggest one of the following:

  - Try a very simple example that you can deacribe completely
    so you can explain it to me in complete detail and I can try to reporiduce
    it.

  - If your database isn't too big (or if you can reproduce this
    with a small database) send me the database. I'll look at it and see if I
    can see what's going on.

I'm not seeing this. What are you trying to add the ZClass to?
Zope 2.1.5 has a fix to ZClasses that makes it work correctly
with ObjectManagers, including ObjectManagers that don't use 
instance attributes to hold sub-objects.  All ObjectManagers should
implement a method, _getOb, that is used to get an object from the object
manager. If you are adding your instance to an object that is *not*
an object manager, then the above error would be expected.

Problem actually solved (by digging arount in how-tos). Some remarks:

Yes, I save the state of the boxes with their properties. Where else
should an object save its state? I mean, "state" IS a property of  the object.
In terms of object orientation, this seems to me to be a much more logical
design than to save session stuff in some non-zope external database or file.

O.k., my ZODB might grow, but is it really that much of a problem (I mean,
a problem that can not be solved by just packing the DB once in a while)? Any
experience with that out there?

The problem with concurrent users switching each other's boxes from one state
to the other only occurs if they use the same objects. What I use in my
implementation is seperate box objects in different user folders. Those objects
only contain stuff that is customized. All "heavy lifting" is done by methods
in the aqcuisition path, so that there is no real duplication of code even
though the complete box structure is duplicated. In a later stage, those objects
(currently just empty folders with a view properties ...) will become instances
of a class.

The cool thing about this is that the portal becomes extremely customizable.
You can add boxes only you can see, use different rendering methods,
style sheets, whatever can be put into a folderish object.

My idea is actually working quite well now. I'll try to make it a ZClass and
put it on the web. But first I want to do some testing.

As soon as I find the time for it, I'll put my ideas into a how-to.

Please disregard this. I didn't perform the test correctly.
I now can reproduce this. Stay tuned.

Message-ID: <38D64B95.99E1F5FA@sistelnet.es>

Hello everyone:

I have posted the second part (Use Cases) of the zope memepool project at
http://zope.sistelnet.es/memez

The final goal of this project is to have a completely functional
memepool-like application, product or whatever, built completely from
scratch, using Zope. The project tries to use a completle Object Oriented
approach to development, and (since I am no Zope guru) feeds from user
comments and recommendations.

Please have a look.

Sorry this update took so long, but this past month has been busy as heck.

Best regards.

Yes, what I didn't know about your design was that the objects in
question were specific to the user.  In that case, and if it is not
expected that the user will want to change his settings with every
session but instead this is a customization feature, then what you
have described sounds like an ideal application of Zope and its
object machinery.

I think it all depends on how frequent the updates are and how many
users you have.  If your site gets to be high enough traffic
and users make frequent enough changes for it to be a problem, you
could always switch to an undo-less backing store for the ZODB and
therefore not have to change your implementation to continue to
scale. Others with direct experience with portal-like sites may have
more useful input.

Are you, by the way, aware of the Portal Toolkit project?  I haven't
investigated it yet, but if you aren't following it it sounds like
something you'd be interested in.  I'm sure they are thinking about
scalability issues there.

Hi all!

and

"Fri, 21 Jan 2000 11:29:10 +0000"

I want to compare them has dates and not strings with the built-in cmp()

can I use for this. Is really anything already  done, I do not want
to go scratchy :-)

OK, so it's not my favourite editor but I thought I'd

Can anyone tell me what I should set EDITOR_CMD to?

'C:\WINNT\system32\notepad.exe' and 'C:\WINNT\system32\notepad.exe %s'
don't do the job. (What's the %s for anyway?)

The %s will be replaced by the filename. This so Notpad knows what file to 
edit.

You will have to double the bacvslahes for this to work, because in Python 
(as in many programming languages), the backslash has special meaning:

  'C:\\WINNT\\system32\\notepad.exe %s'
 
or, you could place an 'r' in front of the string (r stands for raw):

  r'C:\WINNT\system32\notepad.exe %s'

ZopeEDIT will open Notepad for you. When done, you save and close notepad. ZopeEDIT will ask you wether or not you want to save the file to Zope. Click 'Yes', and your changes are now on your Zope server.

Subject: [Zope] dtml-let and MySQL
In-Reply-To: <20000320100802.14614.qmail@web4001.mail.yahoo.com>
Message-ID: <4.2.0.58.20000320162316.00ca5100@195.60.12.162>

As I understand it any variables you set in <dtml-let> </dtml_let> blocks 
are local to that block of code. There's no way to 'pass' them to an SQL 
Method. SQL Methods only use values which have been set within the REQUEST 
variable. The REQUEST variable is where Form variables are held - but Form 
variables only exist until the next Form is called. You can however 
explicitly force values into REQUEST using the syntax

<dtml-call expr="REQUEST.set('yourvariable','yourvalue')">

and these would then be available to an SQL Method.

A tip which I found very useful when working with the REQUEST variable and 
forms is to put the following line into your code
<dtml-var REQUEST>.

This displays all the current values within the REQUEST variable.

There's also a useful How-To on Namespaces which gives more background on 
this area (search for Namespace in www.zope.org).

However IMHO its an area of Zope that needs a lot more documentation and 
tutorials because I don't think it's very intuitive.

I also think it would be nice to have a version of SQL method which allowed 
you to pass the values you want into it - it's beyond me at the moment though.

Good luck

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985DC@pces.cadlab.it>

[Absolute beginner's question...]

I'm thinking to use Zope for an Internet site I have to develop for an
internal client. They will just receive a PC Box from me and will know
nothing about the technology in it.

I wonder if I can safely allow them to drop HTML documents inside Zope. This
would allow to publish their own simple HTML documents without worring about
DTML and the like (I do not think they are interested in developing their
own DTML-enabled sites...).

Is it Zope able to handle plain HTML+CSS+JavaScript documents, without
having to use any DTML file?

Can the user just drop a HTML document in a server directory and have this
document published on the intranet? How can I determine the directory they
can use?

Thanks.

I saw a nearly identical traceback, as well.  You might have to:
        1. play with the imap settings (probably need to change the
           LS* variable in IMAPHACK.py, can't recall it's exact name)
        2. make sure you are running 1.0.4 (a fairly recent version).

Sure.  Although with a little work you can have it automatically get your
intranet's headers and footers, for example.  But just plunking it in works
just fine.

Give them a user that only has permission to access a certain folder.  Then
set up ftp for them and they'll never know it's Zope.

Not exactly, but close enough.  A DTML Document could certainly
contain just HTML code and no DTML, and Zope would happily return
it and the client would render it just as if (say) Apache had
returned it.  I presume you could use the ftp server built in to
Zserver to upload the documents to whatever folders you had given
them permission on.  But keep in mind that all the Zope data is
stored in the ZODB (a single file in the unix filesystem) not as
seperate files in that filesystem, so any update transactions need
to go through Zserver somehow or another in order to update the content.

You might want to consider teaching them the (pretty easy) management
interface, though, as they could use that to upload files directly
from their PC desktops using just their web browser.  Who knows,
they might even decide they want to start taking advantage of Zope's
content management features, and actually start learning DTML <grin>.

Zopists,

Are there any other quoting methods besides html_quote and url_quote?  I
am looking for something that turns periods and minus signs to an
alternative as well.  I guess I could roll my own external method, but
I'd rather not if there are more to choose from.

Doh**2. That now works very nicely. Thanks. One last request:

Any way of suppressing the reflection of the password in the

Message-ID: <Pine.OSF.4.02.10003201131530.4100-100000@batman.tamucc.edu>

Currently, I have a customized standard html header, and would like to be
able to use the same header for all files, but have different titles for
each...I have tried using this in my header:

<title><dtml-let var="'TITLE'"></dtml-let></title>

and then using this in the individual file:

<dtml-let var="'TITLE'" 
value="'My title'"">
</dtml-let>

I only use the "'....'"...becuase otherwise, I get syntax
errors.....however, when I look at the source code on the page, it reads
<title></title>...so apparently this is not working.  Any suggestions?

Thanks,

This is the second report of this bug but I cannot reproduce this, can

You can't.  As security policy, we do not write code that lets Zope open
files outside of the Zope directory.  You can, of course, do this in
your own code, but we do not recommend it.  My first version of
etcUserFolder actually was able to open files anywhere (hence the name)
but I was enlightened by Jim that this is a possible secuirty hazzard.

There error occours because there are pickles in your database that
cannot be loaded.  The 'persistent' information for an object in the
database is a 'pickle', or a serialized representation of the object. 
In order for the object be loaded into memory the pickle needs to be
unwound into an object in memory.

However, this serialized representation does *not* contain any active
code, it's just the state of the object.  In order for the object to
truely 'come to life' the pickle must be matched up with the python code
that all objects have in one way or another.

This error occours when the pickle can be read, but no coresponding
python code could be matched up with the object to bring it to life, or,
an error occoured while object was being unpickled.  Unfortunatly, there
aren't any better iagnostic tools to find why these pickles cannot be
unloaded, and for the most part they are now orphaned objects, you
cannot delete them or manage them or remove them from your database.

I can envision some kind of tool like fsck or scandisk that goes through
your database (probably offline) and lets you examine/purge/fix these
kinds of dead objects.  Ty Sarna has come up with an introspectio ntool
called the Tranalyser that would probably be a good place to start.

from DateTime import DateTime

Now you can instantiate DateTime objects like so:

DateTime(string)

and compare them easily:

if date1 < date2:
  print 'foo'

yourself once, I know ;-)

Thanks for the report,

Message-ID: <Pine.LNX.4.10.10003201247220.564-100000@lawlearn.wuacc.edu>

I'm trying to create several screens to allow my technician to keep a log
of problem reports.

I chose to create a search form.  The data will display in the usual table
form and the user will select the item wanted for display in an update
form with the values shown as default field values.

In the table view, I created a link to my next form in the following way:

<a
href="http://localhost:8080/School/Admin/Computer/displayitem?id=<dtml-var
id>&Submit=Submit&Query">

The problem is that no data gets stuffed into the values="" attributes of
the form which leads me to believe that either I'm not using the
<dtml-sqlvar> tags correctly or I'm not calling the data selected from the
database (mysql) for use in the new form correctly.

I read the how-to on inserting sql data, but I want to create a form that
will update existing records.

Any help will be appreciated,
Joe

Thanks.  One problem that arises when I do this, is that in my
webpage, when I do  "view source" I have ...


stuff
<title></title>           ---> From the standard_html_header file
stuff

<title>mytitle</title>    ---> From the file itself

I guess I am wanting to know how to tell the header to place the correct
title in its own <title></title> portion, and not to add a second
<title></title> line.

Thanks,
Jessica

Subject: [Zope] ExtensionClass
Message-ID: <FRQFOV$I2ZLh74u5vUUBGyDxD3ExLIi5oGV5zoaH@uol.com.ar>

Hi!

I have an ExtensionClass(es) question and, being the 
latest releases of them distributed with Zope, I 
decided to ask it here.

Situation:

1) Class A subclasses 2+ extension classes E = 
{E1,...,En} and perhaps another non extension classes C 
= {C1,...,Cm}. That is, class A(B1,...,Bk): ...., where 
B1,...,Bk are each in E or in C.
2) a is an instance of A (a = A())
3) a.foo(bar) is invoked
4) getattr is invoked in the first extension class in 
the inherited classes list (i.e. the first Bi belonging 
to E)

Question:

What happens then?
I guess that calling Py_FindMethod (inside getattr 
implementation) will trigger a search in instance and 
base classes' dictionaries, but what about the other 
extension base classes and what about the searching 
order?
I can't find any doc on these, so I'm needing your help.

Thank you, Carlos.

(Snip.)

This is due to a fix in Acquisition to a bug that obscured a bug
in the handling of inner ZClasses. Sigh.

We'll be putting ot a release to fix this. In the mean time, if you wish
you can edit lib/python/App/Factory.py and change the line:

    _setObject=Acquisition.Acquired

to:

    _setObject=_getOb=Acquisition.Acquired

You are exactly right!  I took out the title lines in the file, and just
kept the title line in the header, and gave my file a title...and voila!

Yes.

Actually, there is a buglet in XMLDocument that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

In 2.1.5, when you add an XML document, you get a
WrongDocumentException.  This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py.

There may be other problems, however, I'm not very familiar 
with XMLDocument and wouldn't be a good person to find them.

Perhaps you could apply this patch and see if you can find 
anything else wrong.  If you do, please provide me and Amos 
with some sample data and instructions for reproducing the problem.

It did work.  The filename that appears in the traceback is the name
of the .py file when it was compiled to produce a .pyc file.
Since you copied the pyc file, the old name was retained.

Please see my other note for information on a fix to this problem.

It looks like you are trying to use an anchor tag to submit a form. 
This will not work as it is not proper HTML.  You need to use an <input
type=submit...> or some other valid way of submiting the form.

Hi,

sofar I solved the creation process of user accounts. This was quite easy
after I read the code for this. But now I have problems adding new roles via a
specialized interface. I setup tghe REQUEST object correctly, then I call
manage_defined_roles and I get various errors. Is their any method at all to
create Roles besides the management interface of Zope or via External Methods?
Setting local roles is easy, but I can get the role added to the system at
all. Any help appreciated. Thanks a lot.

After reading the how-to that Kevin Dangoor and making some changes from
the management interface, I am able to edit values connected to my Zope
objects. While this is a start, it really isn't ideal. As Nick Henderson
suggested, it would be better if there was a way to do this from standard
DTHML, so that the editing form looks like a filled-in entry form? Does
anyone have any suggestions? Also, a number of the fields in my entries
are coming from "select" lists or checkboxes. This is being done to
control the vocabulary so everyone enters the same term for the same item
(eg. It would be a problem for my application if person #1 calls it "Time"
and person #2 calls it "Time Magazine." Does anyone know of a way to take
the existing values of an entry and pull it into a select list and tell
the list to keep them "selected," or have an idea of a direction to go
in order to attempt this?

There's actually three parts to every error, the error type and
description, and the traceback.  Could you also send the error
description (it's above the traceback) so that I can look at the code
and they to see  what is raising the TypeError (which is the error
type).

What kind of errors?

You should be able to call a method that adds roles just like the
managment interface does.  Have you checked out
lib/python/AccessControl/access.dtml?  At the bottom is a second form
that lets you add roles.

Michel,

I'm trying to use a link on the Report Form to call another form that
displays the single database record with each field filling in the new 
form.  If the user is the proper authenticated user, an update button will
be available, anonymous will only get a listing of the record.

Granted, I'm not doing it the right way. Perhaps my question is how do you
select a value, in this case the record number, and use that value as a
key to pass the entire record to the form for display.  My calling DTML
Method is listed below.

So the question is how can I call up my new form with my selection
appearing as data.

Thanks,
Joe

Message-ID: <4.2.0.58.20000320194209.01654a20@192.168.0.2>

Hello,


I got a similar error with Zope 2.1.5 on Win32 Saturday. Here's how:

- I created a ZClass, TestClassA (it subclassed ObjectManager).
- In TestClassA, I created another ZClass, TestClassB (it also subclassed 
ObjectManager).

So I got ControlPanel / Products / AProduct / TestClassA / TestClassB.

Then :
- I created a TestClassA instance somewhere.
- In this instance, I tried to create a TestClassB instance.

I got:
Error Type: AttributeError
Error Value: _getOb

Somehow this was related to RESPONSE. This error didn't occur when for 
testing I added ", RESPONSE" to the line

   <dtml-with "TestClassB.createInObjectManager(REQUEST['id'], REQUEST)">

in the "TestClassB_add" constructor method.


Cheers.

Alexandre

I'd really like to see a global method that replicates the property sheet
editor but is callable from code rather than the management interface
and can thus be "wrapped"...

There is some sample code somewhere that shows how to mostly do
this in DTML.  I looked at it, but wound up just creating my own
specific editing form anyway, because I couldn't get it to run
out of the box and didn't have time (or at that point the knowledge)
to debug it.

Here's a snippet of code from my custom edit form that does this for
a multiple select property I have.  Hopefully this will help you roll
your own.  'regions' is a lines property defined on another propertysheet
(named 'constants' <wry grin>).  I haven't yet figured out how
to call this variable so I can use it in the addForm.)  I basically
copied this out of that sample code I mentioned above.

  <tr>
    <th><label id=in_regions>In Regions</label></th>
    <td>
      <select name="in_regions:list" multiple size="7">
        <dtml-in regions>
          <option <dtml-if
            "_['sequence-item'] in in_regions">SELECTED</dtml-if
          >> <dtml-var sequence-item></option>
        </dtml-in>
      </select>
    </td>
  </tr>

also,

how can i access directly objects atributes without using <dtml-in

Actually, i need to access to sequences at the same time. That's not
posible with <dtml-in ...>, or maybe i'm lost.


Please send email directly to me cause' i'm not suscribed.

The '%s' gets replaced by a temporary file name, it definitly needs to
be there. I know nothing about notepad.exe, but it sounds like notepad
can't accept filename arguments on the command line. I can't verify this
however. I know people are using ZopeEDIT in Win?? so it must be
something with notepad.

Brian,

It appears to be a good fix.  I'll run with it and let you know how it goes.  I suppose that I should  cc the list as well.

Hi Curtis -

We are going to be releasing a fixed update today - in 
the meantime, if you could try something out to verify 
that it fixes your problem as well, that would be great.

I've attached a file ZRDB.tgz. If you copy that to your
lib/python/Shared/DC/ZRDB directory and unpack it, then 
restart Zope you should be working again. If you have a 
minute to try this can you let me know how it goes? 

Thanks!

Suppose that Bi belongs to E (following the previous 
names) and is not, for example, Persistent, and that Bj 
is Persistent (where j > i).
The problem of the getattr (I mean in Persistent) 
invoked only when the attribute being accessed doesn't 
belong to the instance dictionary or class dictionary 
is still here, isn't it?

Subject: [Zope] my zope has got no pid!
Message-ID: <000a01bf92a4$f172fd00$1cf108c3@SteffenLemke>

Hello there,

something's strange with my zope. I am running zope as my personal zope-user (at least I have started it this way) but I don't get any pid if I say "ps -a". And I cannot stop the server because the script tells me kill: xxxx - no such pid? What's wrong with it?? Is there any additional flag I have to set or unset in the standard-scripts? 

Thank you for your help,
Steffen

Ok this problem is due to the bug in 2.1.5 that also breaks ZSQL
Methods, it is unlrelated to ODBC.  We will be releasing a 2.1.6 that
fixes the problems in 2.1.5 including this one.

try 'ps aux' (on linux at least).  Any other platform, who knows.

I don't know.

No, but certainly your Zope is running with a PID, it must be.  Go to
the control panel, you should absolutly get the right pid there.

Here is what I did to get it going...

EDITOR_CMD = ' "notepad" %s' 

# I put a space in there just to make it easy to see for the email but by
quoting notepad the command line gets interpreted properly.

Subject: [Zope] [ANNOUNCE] Zope 2.1.6 released...
Message-ID: <613145F79272D211914B0020AFF6401914DE8B@gandalf.digicool.com>

Hi all,

Zope 2.1.6 has been released - you can download it from
Zope.org:

http://www.zope.org/Products/Zope/2.1.6/


This release fixes a few issues with Friday's 2.1.5 security
update release:

  o Some bits from the currently development branch got into
    the 2.1.x release branch, causing problems for folks using 
    certain database adapters - this has been fixed.

  o A fix to Acquisition that happened in 2.1.5 caused a problem
    with ZClasses, since some of the code in Factory.py previously
    worked around the problem and now no longer needed to. This has
    been fixed in 2.1.6.

Users of the SiteAccess product should note that the security 
changes in 2.1.5 necessarily require a change to the SiteAccess
product - as he noted in a previous email to the zope list, Evan 
will be releasing an updated SiteAccess shortly.

Also, the XMLDocument product has a buglet that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

Currently, when you add an XML document, you will get a
WrongDocumentException. This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py. A new 
rev of XMLDocument containing this fix will be available soon.

Note that we have also posted "diff" updates as .tgz files 
that will let you easily upgrade an existing 2.1.x site. 
These updates are available for those currently using the 
2.1.x source release or the 2.1.x binary releases for either 
solaris or linux.

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

In an NT cmd.exe shell:

  ...2>C:\temp\zope.err >C:\temp\zope.log

or:

  ...2>&1 >C:\temp\zope.log

should both work.  On Win95/98, I think you're sunk -- the COMMAND.COM shell is
too brain-dead.  You might try 4DOS or another replacement shell.

"Broken pipe" says that the peer process/thread on the other end of a pipe died
without shutting down the pipe cleanly.  You should be concerned, because these
are your "Zope" threads that are dying -- eventually, you will have none left to
service requests.

This problem is a symptom of something inside Zope which is killing off threads,
most likely an unhandled exception somewhere.  Try turning on the
STUPID_DEBUGGER_LOG and see if you get more enlightening log output.

Hi,

well I use the following code snippet in my factory method of the product I am
developing.

<dtml-with "manage_clone(Home, REQUEST['new_id'], REQUEST)">
        <dtml-call "manage_changeProperties(
                        company_name=REQUEST['new_company_name'],
                        title='OS Job Tracking System für ' + REQUEST['new_company_name']
                    )">
        <dtml-call "acl_users.manage_users(submit='Add Role', REQUEST=REQUEST)">
        <dtml-call "manage_defined_roles(submit='Add Role', REQUEST=REQUEST)">
    </dtml-with>

I set the role element of my REQUEST object to a string, which is the name of
the new role. When I look a manage_defined_roles in
lib/python/AccessControl/Roles.py it searches for a submit element in the
REQUEST object that has a certain value. Otherwise it calls manage_access. 

Well, I set submit to the required value, so that _addRole is called. Then I
get the error

    Error Type: AttributeError
    Error Value: aq_acquire

And when I call it without setting the parameters at all

    Error Type: KeyError
    Error Value: SCRIPT_NAME

When I call it with REQUEST=REQUEST I get the first error again.

Any idea what is wrong with my call? I am not using any external method or so
from product, but I develop the product in Zope and use only DTML scripting,
cause this is sufficient for my task.

I am running Zope 2.1.4 as a standalon zserver. May be this helps too.

Any hint would be really fine.

Best regards,

    Oliver Andrich

Hi,

I just discovered something strange. At least I think that it is strange. I
can assign users Roles that don't exist at all in the system. In my last Email
I tried to create a Role in a system wide context. Well, know I removed the
role add code and just added the user with a fantasy role. Now the management
screen can't handle the user anymore cause the role doesn't exist. But when I
do a acl_users.getUser('admin').getRoles() I get the fantasy role I
    specified. Ok, this is not the solution, but should the manage_user code
    check if the role that is specified exists at all?

Bye, Oliver

start.bat is all you need.  It will leave a dos-box open, but that's fine.  It

Steffen

This happens when you rename the Zope directory after installation.

The stop script has a hardcoded directory in it.

If you edit the stop script and change the old directory name to the new one
all works as expected.

Vladimir,

I just had this same thing happen, and bypassing the factory worked.
I changed the calling method from calling "maClass_factory to
myClass_addForm, and the add method worked fine.  That seems very buggy
to me.

The traceback was posted onthe zope-dev list this morning.

Here it is anyway:

<dtml-with "WorkDayClass.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-call "propertysheets.WorkDay_properties.manage_changeProperties(
             work_date=REQUEST['date'],

 <dtml-call reindex_object>
<dtml-with>

Now I get:

Error Type: AttributeError
            Error Value: _getOb

Message-ID: <20000320232355.87383.qmail@hotmail.com>

Hi,

How do people generate id keys (surrogate primary keys)
in Sybase+Zope? There are some recommended ways of doing it
in Sybase with stored procedures but I can't run stored
procedures in Sybase.

I am looking at heavy-traffic strategies. So I need something
slightly better than a simple increment table for the keys.

Any recommendations? Thanks in advance.

D'oh!  The environment variable which Zope checks for is STUPID_LOG_FILE:

 * If it is set to a blank string, Zope writes the verbose logging
   to stderr;

 * If it is a non-blank string, Zope opens it as a file and writes the
   verbose logging there;

 * Otherwise, Zope suppresses the verbose logging.

Ayup, there have been several threads reporting such restarts lately -- have you
been following them? (some were on the zope-dev list, I think).

Just to add my two cents:  I've seen these as well, usually connected to
someone disconnecting from downloading a page mid-way, usually also
connected to zope going into a really tight 'select (0,1), select (0,1,2),
select (0,1,2,3), select(0,1,2,3,4), etc loop - until it runs out of fd's
it's allowed to open, crashes, and needs restarting.  Oh, and only when
running with FastCGI.

Redhat 6.1ish, glibc from rpm glibc-2.1.2-15, python 1.5.2 from rpm
python-1.5.2-7, apache from rpm apache-1.3.9-8.

My response so far has been to whack a while : ; do ... done loop around
the kickoff command in ./start, and run the whole lot under screen -dmS.
STUPID_LOG_FILE didn't produce anything that was immediately useful to me
:(

I've just upgraded to 2.1.6, and so far I haven't seen the problem, which
may or may not be a good sign ;)

Hello all,

I have the following code fragment in a method called
CategoryCustomizationForm contained in the folder /News:

<dtml-if preferences_saved>
  <hr>
  <b> Your preferences have been saved </b>
  <hr>
  <dtml-call "manage_changeProperties(preferences_saved=0)">
</dtml-if>

where "preferences_saved" is a property of the folder /News.

In the folder /News, the security view verfies that the permission of
"Manage properties" is allowed only by those in the "Manager" role. In
order to allow all authenticated users to use
the "manage_changeProperties" method in "CategoryCustomizationForm", I
assigned the proxy role of "Manager" to "CategoryCustomizationForm".
However, zope still only allows users in the role of Manager to access
"manage_changeProperties" in my form. In other words, the proxy role
assigned to the method "CategoryCustomizationForm" failed to override
the permissions of its containing folder /News. As a temporary fix, I
gave the "Authenticated" role permission to "Manage properties" in
/News. This works with regards to allowing all authenticated users to
access "manage_changeProperties" in my form. However, in the long run, I
don't want all authenticated users having manager type access to all
properties of /News. I have this failure of proxy roles in other areas
of development too, such as dtml creation of folders via manage_clone.
Is there something I'm missing about how to use proxy roles? Thanks for
your time.

Unfortunately the IDENTITY column is not a good option.

According to our local Sybase expert, The IDENTITY columns
are just too buggy to use, even after the newer releases of
Sybase. They cause too many troubles, that is why we are
looking at alternatives. In older versions of Sybase, the
problems were so severe that they would cause the database
server to crash. Some drawbacks that were mentioned:
(some are fixed, but these are not the only problems...)

(1) When database server crashes, apparently the IDENTITY
    column jumps to the next block of values, so the table
    index space become sparsely populated, and you may hit
    the roll-over situation earlier than expected.

(2) When using BCP utility to download and upload tables,
    there are some problems with the IDENTITY columns, too.

(3) It is hard to access the values of the IDENTITY column
    when you are in multiple SQL statements.

Anyway, there seem to be too many problems, so the IDENTITY
column approach has been discarded. :(

regards,

Hung Jung

I've released LocalFS v0.1.7. It hasn't been tested extensively so I've left the
bits for v0.1.6 up on the site. I'm just too excited to wait. :)

The url is: http://www.zope.org/Members/jfarr/Products/LocalFS

Enhancements in v0.1.7:

- Added the ability to customize mappings between file extension, content-type,
and Zope object class.
- Added the ability to customize content-type to icon mappings.
- LocalFS objects now work with the <dtml-tree> tag, so they can be traversed
using the navigation menu.

(plus a few bug fixes)

If you try it out please let me know what you think or if you find any problems.

Thanks,
-jfarr

Subject: [Zope] ZClasses and clone/delete methods
Message-ID: <14550.61379.392791.186258@antares.int.plain.co.nz>

I need to know whether I can set up clone and delete methods in a
Zclass that automatically get invoked any time someone deletes or
copies an instance of that class from the management interface (via
cut and paste or whatever). 

What I'm doing is creating a simple link class that just stores the
key to a RDBMS row that contains all the details of the link
(description, URL, clickthrus etc). The trouble is that when a link is 
deleted from Zope, it needs to touch the db record or that record will 
become orphaned - ideally the db record needs to keep a reference
count of the number of link objects out their, and they need to
increment or decrement that count as they get copied and deleted.

So can this be done with a ZClass (if not, why not :-)) and if it
can't, how can I do this with a Python Product (given that I've never
written one!).

TIA,
John.

Message-ID: <38D6F845.A010DBE2@suprize.com>

Hi,

    I have Zope 2.1.5 and Oracle 8.0.5 running on the same Linux box.
ZOracleDA was installed successfully and bridged Zope and Oracle.
I can call my stored procedure by creating Z SQL Method like:

    begin
    procName(arg1, arg2,...);
    end;

But I cannot get return arguments (OUT args) no matter how the Z SQL
Method is set. I have tried the interfaces mentioned in DCOracle
documents, but failed. The only work-around I've found is creating 
extenal methods and import DCOracle via python. Is there any way
to get the OUT arguments from Z SQL Method? Thanks a lot!

Message-ID: <1F176F2C2977D311B3300090270E637887B105@scl-exch.phoenix.com>

I've read
http://www.zope.org/Members/Zen/howto/FormVariableTypes
and a few other HOW-TO's and still haven't figured out
how to make use of the :record type in form variables.

My form looks like:
<form method="post" action="processForm">
<input type=text name=choice.1:record>
<input type=text name=choice.3:record>
<input type=text name=choice.10:record>
<input type=submit>
</form>

Now processForm need to tell which and how many choice.x:record are entered.
This works:
	<dtml-var "REQUEST['choice']">
that's as far as I can go. I want to do:
	<dtml-in "REQUEST['choice'].keys()">
		<dtml-var sequence-item>:<dtml-var sequence-value>
	</dtml>
but it doesn't know what "keys()" is.

Question: how do I get the keys and values for this "choice" record in
processForm?

Thanx,
-Tanming Fong

iI'm going to have to disappoint you.

- I never published the object, it was simple and not that general. Also, I cannot release it now, because it was written while working for my previous employer.

- The site for which I used it was for a big Dutch youth event, and now that it has taken place the site has been taken down again.

Record objects do not implement a mapping interface.  Form elements are
turned into attributes of your 'choice' object, so your objects has
instance attributes named 1, 3, and 10.  You will need to use
_.getattr() to access these attributes since numbers are not very good
attribute names.

It might be a good idea to look into a new ZPublisher type called
:dictionary (or :mapping) that works much like :record, it would be
fairly trivial to implement, want to take a stab at it?

Subject: [Zope] ZODB Couldn't load state - help please
Message-ID: <38D73050.8A2546B8@knoll-is.de>

Hello Zopers,

I just joined these mailing lists. I have a boring problem I can't
understand. I wrote this little program:

import Persistence
import ZODB
import ZODB.Transaction
import ZODB.FileStorage

class dbclass(Persistence.Persistent):
	def __init__(self):
		self.thedata = 'testdata'

def getdata( request=None ):
	name = 'somename'
	db = ZODB.DB(ZODB.FileStorage.FileStorage('myfile.fs'))
	connection = db.open()
	root = connection.root()
	if not root.has_key( name ):
		print "initialising"
		root[name] = dbclass()
		get_transaction().commit()
	r = root[name].thedata
	connection.close()
	return r


This program works very well if it is started directly using the python
interpreter. But if I call it from Zope using 'Try it' in the management
console it works only one time. The second call of the function results
in:

Zope Error

          Zope has encountered an error while publishing this resource.

however, i'm also looking at other perl/php products.

my Q:
-anybody on the list have deployed confera/zdiscussion on  a large site?
-what will a lot of traffic do to Data.fs?  will i have to pack often?
-i'm looking at modifying zdiscussion to store to an RDBMS.  anybody done that
already?  if so, mind sharing how you did it?
-i'm not a python programmer.  and i would like to implement filtering for
certain words/malicious html tags.  i see an external method here.  any other
solution?  dtml maybe? :)

i thank all for your help, pointers, docs.

I had the same experience a few days ago with a 2.1.4 installation running
under Win98. I have a couple of different Zope instances running on Linux and
Windows, but that was the first data loss. It seemed to me as if the session
had been running in "demo" mode so that changes would not be really persistent.
As in Alexandre's case, I first thought I was dreaming because there was no
hint of my data except for the log files.

I suggest some further investigation into that. If Zope really lost things that
easily, I'd consider not using ZODB for production sites ...

BTW: In my case it also was a Windows system crash that caused the data loss.

This sounds like Win98 is using a write-cache that didn't get flushed to disk
because of the crah. IIRC, Zope forces write cache flushes, but it could well
be that Win98, being a client-patform, ignores that for performance reasons.

Then again, who'd use Win98 for production sites?

Try %1, instead.  %1, %2 etc stand for a commands first, second 
... positional parameter in the MSDOS/Windows/Windows NT

*Sigh* Did anyone read my reply to the original message?? A backslash has
special meaning in python! And positional parameters have nothing to do with
python either!

In python (as in many programming languages based on C) \n means newline. Just
fire up a python interpreter:

  >> repr('C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\012otepad.exe %s'

\012 is the octal representation for newline. Note that, as \W and \s are
meaningless, they are interpreted as if you used a double backslash.

The solution immediatly becomes clear:

  >> repr('C:\\WINNT\\system32\\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'
  >> repr(r'C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'

ZopeEDIT uses the string to build up a command to feed to the system. It uses
the default python % operator to replace the %s (which is a C-sprintf-like
string formatting code) with the filename of the temporary file it creates.

Please, next time, use the python debugger or something to see what goes
wrong. Paul has long since gotten ZopeEDIT to work, BTW.

Subject: [Zope] Weird ZSQL Method thing...
Message-ID: <38D760E4.F25D1D00@nipltd.com>

Hi,

This is weird, I've got a solution but I don't know why I need to use it...

I have a DTML Document that uses two ZSQL Methods, something like:
<dtml-in item>
  ...the item ZSQL method returns cid...
 <dtml-var cid>
 <dtml-in case>
    ...the case ZSQL method takes cid as a required parameter
 </dtml-in>
</dtml-in>

Now, using this returns an error: Bad Request: [cid] 
which I've grown accustomed to seeing when a requried parameter is missing.
However, if I dtml-comment out the second dtml-in, it works fine and the correct cid is displayed by
the dtml-var.

The only way I can get it to work is to make the second dtml-in look like:
 <dtml-in case(cid=cid)>

I really don't understand why I need to do this and why the 'case' ZSQL method doesn't just pick up
cid from the current namespace...

Any ideas?

Chris

Um, more or less (apart from the quotes). The ZSQL Methods use namespace
different from than normal DTML documents/methods (though I don't
exactly know how). Therefore you have to call them explicitly with an
argument.

If this is true, it's really counterintuitive and should be changed if at all possible.

If it's specific to ZSQL methods or in otherwise confusing situations, then there's even more reason
to change it...

Anyone got any comments/suggestions?

Subject: [Zope] FSSession and external methods...
Message-ID: <v04220807b4fd1bb332c0@[128.240.198.13]>

Hi all,
Anyone got any experience with FSSession and external methods 
(actually a PythonMethod).

I want to get the data out of an FSSession object using this construct-type

<argument>self</argument>

FS = self.FSSession
out = ""
for k,v in FS.items():
     out = out + "K:%s, V:%s<br>" % (k,v)
return out

and get this;

<!--
  Error type:  AttributeError
  Error value: _v_data
  -->

Looking at FSSession.py, _v_data is there as part of the FSSession class;
     def items(self): return self._v_data.items()
but it's not getting through to the method.

Anyone got a fixe for this? I need to do some heavy processing with 
the contents of the FSSession object so I can't *really* use DTML.

TIA
tone.

have you given roles to the user???
to protect the folder, I suppose you have created a role 'ROLE', and said
that anyone but those with the role 'ROLE' are able to view the folder.
however, if the users in the NT User Folder are not given roles, there are
two case:

when you create a NT user folder, you have to choose whether default
behavior when a user is not given roles is to acquire user settings from
higher user folders or not.

- if default behavior is to acquire settings, due to the very nature of user
folders, NT User Folders says the user *does not* exists if no roles are
defined, to allow higher user folders to handle the user. this is the
default for a nt user folder created in a sub folder

- if default behavior is not to acquire settings, NT User Folder always says
'yes' when the user is asked, but if no roles are defined, the user is
assumed to have to anonymous role. this is the default for a nt user folder
created at the top level

if roles are created for a user, it always exists, what ever the default
behavior is.

back to your problem: if you choose not to acquire user roles, all users for
which you didn't give roles are *anonymous*, so they have no rights on your
protected folder.

This is not true.

Method A:

<dtml-with "_(bob='uncle')">
  <dtml-var B>
</dtml-with>

Method B:

<dtml-var bob>

_will_ print 'uncle'.

It is specific to ZSQL Methods, they create their own fresh namespace. 
There may be a good reason, I can't think of one.

ZSQL Methods create their own namespace (I don't know why).  You must
explicitly pass them arguments.  You can, of course, pass then entire
namespace:

<dtml-in "case(ns=_)">
  ...
</dtml-in>


and in your SQL Method:

<dtml-with ns>
 ...
</dtml-with>

This is, like all of my advice, completely untested and off the top of
my head, but it should fly.

We have deployed a heavily modified Squishdot site that handles around
30-40K requests a day.

Depends. Trafic by itself does not increase the size of Data.fs.

Now but we will have to. After 3000-4000 postings Squishdot is very slow
and I suppose zdiscussions too.

An external method will be appropriate. Forget DTL for such task.

IMHO, this isn't true. I have several ZSQL methods which have named parameters. 
It appears that they can get these parameters from REQUEST and possibly (I can't remember and

Can anyone who knows say why this is the case and exactly what the critera are for something being

You need to call FSSession before you can use it, as in DTML otherwise the
data will not be loaded into _v_data. I have just tried the following and
it works:


FS=self.FSSession
FS()
out=""
for k,v in FS.items():
   out = out + "K:%s, V:%s<br>" % (k,v)
return out

Martijn, you're right. Nobody would use Win98 on production systems. But quite a
few people use it on their notebooks or home PCs for development, I guess. At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Well, I don't think that is the optimum solution, especially for big sites. 
Even though that is the Zope way of doing things, I hate the idea that I 
clutter my ZODB with files. I would suggest you add a property called 
attachments to your Class which points to various URLs and then serve the 
files via Apache. You may want to use PCGI to do this.
We just switched to PCGI and now we serve Images and Documents from another 
port via Apache (we can also use SSL now). That helps to keep the I/O 
stream to the ZODB file moderate. Remember, ZODB is just big one file (even 
though Zope does a lot of caching). You could also check into LocalFS, 
which is nice in some cases (even though we were unsuccessful to upload 
files, using it.)

Stephan

Subject: [Zope] Modifying Standard Error Pages
Message-ID: <Pine.LNX.3.96.1000321140832.11696D-100000@marvin.nipltd.com>

I'm currently trying to modify Zope's standard error pages in order to
have errors (such as 404 not founds or DTML errors) e-mailed to the 
webmaster as they occur.

At first, I thought this would be as simple as modifying the
standard_error_message document found in the root of the Zope
installation, but it appears that changes to the file do not get displayed
(even after forced refreshes) and thus it doesn't seem to be in use.

A search on zope.org lead me to find the real error message embedded in
<zopedir>/lib/python/OFS/Application.py - I've modified this and it
appears to work, but doesn't support HTTP related errors such as 404s.

After a bit of a search, I've tracked down HTTP-related error reports to
<zopedir>/lib/python/ZPublisher/HTTPResponse.py but, while this can be
modified, it doesn't support DTML as the HTML error message is returned
without apparently being parsed by Zope. As a result, I can't have
dtml-sendmail send an error message report.

Okay, I could modify HTTPResponse.py to send a mail using something like
Python's smtplib, but before I do that, have I overlooked the obvious and
is there really a much cleaner, easier way to modify the error pages
without delving into the sources?

Thanks in advance!

Neither. Add orphan=0 to the tag, and you'll feel sane again.

if ommitted, orphan is set to 3. This means that if the last batch is smaller
than 3 items, that batch is added to the one but last batch. See it as a
'minimal batch size' parameter.

This is different.

When you call a method 'by name' (<dtml-var methodName>) then the DTML
machinery will magically try and line up any arguments to that method
with any names in the namespace.  It will do this for any kind of method
that accepts arguments, DTML Methods, SQL Method, ext methods,
PythonMethods, and methods written in python of the object this()
etc...  _However_ if that method is a SQL Method then as soon as you
enter the method any reference to <dtml-var name> in the SQL method will
NOT find the name in the previous DTML namespace.  If you want a name in
the DTML namespace to match an argument, that's a different matter all
together, and it will work, if you want to <dtml-var name> in a SQL
Method and 'name' is in the namespace of a calling DTML method, then it
won't work.

Have a look at:

  http://www.zope.org/standard_error_message/view_source

and you'll see how the Zope.org site handles 404 Not Found.

In the current CVS they do.  Tanming, if you're using a source code
distribution of Zope you can change the definition of class 'record' in
ZPublisher/HTTPRequest.py to the following:

class record:
    def __getattr__(self, key, default=None):
        if key in ('get', 'keys', 'items', 'values', 'copy', 'has_key'):
            return getattr(self.__dict__, key)
        raise AttributeError, key

    def __getitem__(self, key):
        return self.__dict__[key]

    def __str__(self):
        L1 = self.__dict__.items()
        L1.sort()
        return join(map(lambda item: "%s: %s" %item, L1), ", ")

    __repr__ = __str__

Cheers,

Are these batches of records the 'last' batch in the ZSQL query?
If so, it's the 'orphan' parameter kicking in, which *I believe* is set to 3.

If you have 19 records returned with a batch of 4, you get
1-4, 5-8,9-12,13-16,17-19 - no problem there

If you have 9 records returned with a batch of 4, you *would get*
1-4, 5-8, 9 (on it's own).

The 'orphan' parameter would make the last batch return 5-9 (ie 5 records).

It's described in greater detail in the ZSQL users guide...

Neither.  The in tag by default does not like orphans (result batches
smaller than 'size').  Set 'orphan=0' and sleep in peace that your
sanity is intact (and that the in tag is bug free).

Here's something that worked for me, it's got extraneous imports and 
stuff ('cos it's the front end of something bigger), but it does 
work. I add nnn_ to the beginning of file names so I can have more 
than one file called 'test.doc' in the directory, and I've not 
finished the URL stuff yet, but it certainly uploads normal files to 
LocalFS (probably because it bypasses the LocalFS machinery all 
together ? :) .

add_details is a ZSQL method that adds info about the upload into a database.

Martijn,

I think the problem is that any changes made to standard_error_message don't appear to have any
effect. I've tried just simply changing the text, add ' - wibble' after 'Zope Error' and the old
error message is still displayed, even after restarting Zope...

What's going on?

Is there some method such like with SiteAccess that you have to 'set' a DTML method as the standard
error message or is something else causing the old error message to be displayed?

HYCH,

Chris

I have no idea. I don't use SiteAccess, so I don't know what influence it has
on this issue. I can change standard_error_message just fine here. Try and
understand what the default code does first, then try and make a few
educated-guess changes to that code.

Does anything show up in the undo log? After a change, does the edit window
have a message 'Content changed [Date]' just below the tabs?

You've seen this before?  Great you're the first person who actually
gives me hope I'm not insane.  We have been running 7 sites from a
single zope install replicated across 3 servers.  Two of the servers
experience frequent Zope restarts (as often as every hour).  The third
server running an older version of Redhat (6.0 I believe) and
glibc-2.0.7-29, and hardly ever restarts.  

We are running Redhat 6.1, glibc from rpm glibc-2.1.1.6, python from rpm
python-1.5.2-7 and Apache/1.3.9 mod_fastcgi/2.2.3 and Apache/1.3.11
mod_fastcgi/2.2.3.

We have even gone as far as to modify FCGIServer.py to produce "debug"
output  to determine which requests go unanswered at the point of
restart; hoping this would lead to some suspect DTML or ExternalMethod
code.  No luck.

We're waiting a bit to upgrade to see how it shakes out w/ SiteAccess
etc.

We've also recently bumped cache *WAY* up, 450,000 items, w/ 5 minute
target max between accesses.  Which has resulted in 200M of memory for
the process.  This appears to have lowered the number of restarts, but
not eliminated them.

In your experience with this problem have you noticed /manage and or
traffic volume to have any impact on the frequency of restarts?  We've
been looking everywhere to determine what may be going wrong, and have
experienced the most restarts when traffic and /manage volumes are up. 
We unfortunatly have our most /manage volume within the same timespan as
our heaviest traffic.

Hopefully we can find a solution to this.  Thanks for the feedback.  Let
me know if you make any headway.

Hello,

I still can't figure out why my DTML document gives me the following
Zope error :

    Zope Error

    Zope has encountered an error while publishing this resource. 

    Error Type: AttributeError
    Error Value: __call__


when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?


Thanks in advance,
Greeting,
Eric

This is what happens when an exception is raised while rendering
standard_error_message (obtained through acquisition).

ZPublisher renders the default standard_error_message, rather than let
a problem go unreported.

Hi,

As I found out - you can not index numbers and therefore not search 
for dates using the zCatalog.

But I was wondering 'bout workarounds. I thougt maybe if I could 
change the bobo_modification_date to one of my own. That I could 
search for. But that seems like a pretty crappy workaround...

Ideas.... anyone ???

Has anyone modified the Zope index method to also index numbers ??

I think that's probably wrong. The thread-safety-ness of MySQLdb is that
two threads can share the module. You can't safely share connections, but
this is more of a MySQL limitation than a MySQLdb limitation. Of course,
you can share connections if you wrap a mutex around it so that only one
thread uses it at a time, but it is far better to have multiple
connections: Each connection is a seperate MySQL thread on the server
side.

The old MySQLmodule was probably thread-safe, but not thread-friendly: If
you ran a blocking operation (like a query), it would block all the
threads (i.e. it did not give up the Python interpreter lock during
blocking calls). This apparently causes really bad performance with Zope.

I may be deficient on Zope zen, but it seems like you would definitely
want to have several connection objects around, perhaps one for each ZSQL
Method, so that these can all work in parallel. From a security
perspective (i.e. you aren't just paranoid, you know they are out to get
you), this may make sense, as you can set up seperate users in MySQL with
very specific privileges, so each connection object can only do one thing
and can't be hijacked for something else.

Yup, just discovered this myself. :-) I put a buggy dtml expression in the
document and Zope displays a default message rather than the custom one
I've generated - removing the buggy stuff brings the custom version.

Thanks to Martin for pointing me to the 404 handling on zope.org, I've
solved the initial problem I was having with getting changes recognised in
the standard_error_message in Zope's root, and now have it mailing a basic
error report to the webmaster.

There are a few issues Chris noticed when he was doing some stuff, but I'm
going to take a look at these further before posting more on the subject.


Cheers,

John

Have you looked at the Zope.org error message and played with that? You should
be able to do a RESPONSE.redirect I think.

Martijn,

Yeah I look and even copied the code and fixed it to work on my server but
doing a redirect doesn't seem to work.  At best I get a blank page with no
redirect taking place.

Oh well, I'll keep on experimenting.

See ya

Hi Zopistas!

I need to get rid (completely) of some items in REQUEST that were 
passed from a form. Is there an opposite to REQUEST.set() that 
deletes instead e.g. REQUEST.delete() or so?

You may want to look at Pavlos Christoforous' FSSession or Anthony
Baxter's SQLSession products to make this happen.  Look on zope.org.

Not a problem. Use ZSQL Sessions and an update SQL statement have it fed in
from a Zope form. Do a little error checking and Bob's Your Uncle.

I don't think this is true. Catalog does not index numbers in TextIndexes,
but I think a FieldIndex would work fine. I'm pretty sure I've done it (with
dates, even), but not 100% sure.

Just make sure you use a FieldIndex, and I think you'll be fine.

Hi,

    Take a look at the FSSession and SQLSession products. They allow you to
store data on the server for each user, and I think it would be pretty easy
to implement a shopping cart that way.

Hi,

  I went thru mailing list but I did not find a
response to my problem.

I've written simple form with one text field and one
file type:

<form action="/content/result" method="post"   
ENCTYPE="multipart/form-data">
<input name="c_title" width=30 value=""> 
<input type="file" name="c_body:file" width=30>
<input type="SUBMIT" name="SUBMIT" value="Submit">
</form>


result method is:
....
<dtml-call "manage_upload(REQUEST['c_body'].read())">
<dtml-var REQUEST>
....

When I press Submit button I get

Error Type: NameError
Error Value: manage_upload

Any suggestion?

b) How can I simply affiche (if I find a PB) the
upload content in browser?

c) How can insert uploaded content in MySql. I Have to
use:

VALUES
(
'<dtml-var c_title>',
'<dtml-call
"manage_upload(REQUEST['c_body'].read())">'
)

It works? it seems bizarre?

Thank's

The REQUEST object is defined in ../lib/python/ZPublisher/BaseRequest.py. I
don't see a delete there, but by studying that code, I'm sure you could
easily implement one.

Subject: [Zope] newbie CGI question
Message-ID: <Pine.OSF.4.02.10003211327080.9449-100000@batman.tamucc.edu>

I currently have a site that uses numerous perl cgi scripts....I have
successfully managed to transfer all the static pages to Zope...however,
what about CGI scripts?  Does Zope support them?  Can I use the Zserver
with these scripts or should I use the other server (with Apache)?

Also, from the Zope experts out there, I need your opinion.  I am
considering using Zope for my existing web site (it's fairly large)
...however, I would still like to continue to use perl/cgi, (have a
lot of time invested in my already existing scripts), and not use much
Python (no flames please...haha).  I like the graphical capabilities of
Zope, and the ability to assign roles to  certain users...but I don't know
if this is worth switching, especially if I am going to continue to use
perl/cgi (if that's even possible)...any suggestions out there?

Thanks in Advance,
Jessica

It seems to me that all this would require is passing the "_" namespace in place
of the REQUEST when calling the ZSQLMethod -- am I missing something?  Values
found in the REQUEST would still be found, but would be overridden by any
intermediate namespaces (e.g., from dtml-in, dtml-with, or dtml-let).

[RH] REQUEST is a python dictionary, but probably one that DC has altered
for security (or other sound reasons). I once used REQUEST.clear(), which
flushes the whole REQUEST  (this was necessary because I wanted to do a
batch operation on a fileobject of 500K , but didn't want to pass it around
several times). This worked, I believe (but I never tested this through).

Martijn, you're right. Nobody would use Win98 on production systems. But
quite a
few people use it on their notebooks or home PCs for development, I guess.
At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS
in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and
restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Joachim.

[RH]Hm, I have been developing for quite some time on an feeblish win95
machine at home, which repeatedly crashed, but I have never ever lost
committed transactions. Strange.

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in

I still can't figure out why my DTML document gives me the following
Zope error :

    Zope Error

    Zope has encountered an error while publishing this resource.

    Error Type: AttributeError

when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?

[RH]Can you send us more detailed information:
the exact dtml for the local and the subobject method and the traceback of
the error (you can get it by viewing the source of the error page)

The REQUEST object stores form data in its .form member, which is a Python
dictionary.  You will need to find a way to execute the statement, "del
REQUEST.form[ 'variableToErase' ]", or the equivalent expression, "delattr(
REQUEST.form, 'variableToErase' )", neither of which can be done from DTML or
from PythonMethods (ergo, must be done in an ExternalMethod or done from a
Python product).

My Very First External Method (TM) -

def removeRequest(REQUEST, item):
    "Remove an item from a REQUEST.form"
    try:
        del REQUEST.form[item]
    except:
        pass
    return None

And invoked (once instantiated by the Management Interface) with

<dtml-call "removeRequest(REQUEST, 'form_variable')">

(Note that the except clause should really be trapping for KeyError -
version 1.1 will definitely have this :-).

Subject: [Zope] Installation Directory Problems in a W2K install
Message-ID: <PKEBIHPBEGMAPMNHFPCFGEGNCKAA.jlv@volition.org>

Hi.

I installed Zope 2.1.6 on a W2K machine and have one problem installing
additional components.

I have tried to install TinyTable, Squishdot, Photo, ZPhoto-Album, and
others but NONE of them get noticed by Zope when re-starting the service.

A clue, I believe, is in this error message when trying to "import"
ZPhotoAlbum.zexp:

---
Zope Error
Zope has encountered an error while publishing this resource.

Error Type: Bad Request
Error Value: File does not exist:
C:\PROGRA~1\ZOPE-S~1\import\ZPhotoAlbum.zexp
---

Shouldn't that directory be:

C:\PROGRA~1\ZOPE-S~1\inst\import\ZPhotoAlbum.zexp

???

None of the lib installations that would be in ..\inst\lib get noticed upon
restart, which leads me to think that somewhere in the installation it
doesn't have the "installation" setting correct.

I always thought the inst directory was used by Zopeat install time and only
then.

Any products should go into <zopedir>/lib/python/Products

Any zexp files hould be in <zopedir>/import

You shouldn't need to put anything in the inst directory.

I'm pretty convinced it's related to glibc version - the fact that a strace
of the process shows it repeatedly opening/selecting over more and more
fd's just before the process goes away suggests some sort of funky error
handling to me - maybe one of the socket handling routines had a change in
what error it produces between glibc versions?  Anyway, I haven't had time
to sit down and properly dig.

2.1.6 suffers the same problem.

I can reproduce it instantly with a large enough page - stop the request
mid-way, the closing of the socket to the client while Zope is serving the
page up seems to be what causes it to go into it's loop, then die.

Mondo apologies to the zope crew for not putting this in the collector - I
had hoped to find the actual problem (and maybe a solution) first, but ran
out of time :(

Sometimes you do, sometimes you don't. I know that sometimes I can acquire ZSQL
method parameters from the request. Sometimes I have to provide them explicitly.
I haven't been able to figure out what the rules are, either. If anyone out

Ok,  I finally did it.  I got my boss to slip a nice little application
server in the budget.  So here I am trying to spec out a nice Zope server.  
 
What should my priorities be when building this beast,  I think we'll be
able to spend about $10 Grand on this beast.  We will be running a secure
site using Apache and OpenSSL,  and we are targeting about 100 continuous
concurrent users.  I have already set SOME priorities, because uptime is a
big issue so the server will have redundant power supplies and hardware RAID
5.  
 
Beyond that,  what do you suggest.  Is memory more important than processor
speed?  Is it important to go with a Multi-processor server or will Zope/
Linux take advantage of a multi processor setup?  
 
 
Dream a little server for me :)

You will have to use Apache + mod_perl + mod_rewrite + Zope.
This way, you send the CGI requests to the cgi-bin, and the
rest requests to Zope. The details could be somewhat involved. :(

(see the following quote in
http://www.apache.org/docs/mod/mod_rewrite.html

`` Despite the tons of examples and docs, mod_rewrite is
voodoo. Damned cool voodoo, but still voodoo. ''
-- Brian Moore
bem@news.cmc.net
)

But it is definitely worth it. And I would guess many people
out there actually use this configuration.

I guess it is possible for someone to write some Zope product
for Perl (a la mod_perl), but it would be major engineering to
be fully compatible with Perl. If you don't mind re-launching
the Perl interpreter every single time (I know, it's primitive),
it's easy to execute the perl command from a Zope external method.

For now, the best bet is probably Apache + mod_perl + mod_rewrite +
Zope.

Hung Jung Lu ,
Along these same lines, I have a C++ CGI App that I would like to call from
zope.  It requires a couple of parameters.  The app can either return HTML
or I can have it save the output to a text file.  Ultimately, the text will
need to be displayed to the user from Zope.
Q1.  How does one call a C++ CGI program from Zope?
Q2.  How do you supply the C++ CGI program with "command line" parameters
from Zope when making the call?

Thanks,

Eric.

The intent of ZOPE is to replace writing CGI scripts. Zope itself often
runs as a large persistent CGI script. It has several advantages over
traditional CGI scripts detail on zope.org.

The general answer is that you'll need to put the CGI scripts in a
non-ZOPE location to use them.

I suggest deprecating your CGI scripts in favor of ZOPE classes.

Oh boy... 10 Grand?

IBM Netfinity 5500 M20

- Dual 700 MHz
- 5 x 9.1 GB RAID 5
- 2 GB RAM
- Dual NIC Cards
- RH 6.1 

Should be about 10 Grand. That thing is ROCK SOLID. It could eat 100
Concurrent users without a napkin. Can handle up to 4 GB RAM, 120+ GB of
Drive and 4 Processors. Almost everything is hot swappable (power, fan, PCI)
only time you would have to bring it down would be to so you could take it
home.

The other way to go would be to get 2 x Netfinity 5000 (Dual 700 MHz, 1 GB
RAM, 3 x 9.1 GB RAID 5). Load balance them and you are golden.

Enjoy...

Subject: [Zope] Zope hosting
Message-ID: <20000322010840.A1674@rosa.sferacarta.com>

Hallo! I'm thinking about using zope to develop some sites.

May you please advise me about a Zope hoster?
I've looked at those listed on zope.org, but some of them offer
just 20MB or have most of the site written in german.
One of them I can't even reach, others don't mention zope on
their pages, or are a bit on the pricey side.

I need a flexible, expandable solution. I may need 40MB and two
domains for a start, and more in the future. I have to install
my products and use pgsql or mysql.

Shell access is welcome, too..

Do you have some suggestion?
Which ISPs do you think are best?

 - OR -

Do you think I'd better install zope as a normal user, on one of
those cheap ISPs that give me 500MB ?


Thank you very very much.

Message-ID: <38D80AF9.3FE3909F@netspace.com.mx>

Hello,
I recently started to work with php (+ Apache), and now I found Zope. At
the first sight, Zope seems to be faster than php, but I don't know if
it's my php application that is not so complex than Zopes objects. So I
would like to ask, is there a benchmarks or articles or any sources that
discuss about performance and developing PHP versus Zope? Also, i am
cuirious, was Zope developed to replace PHP in the future? And what if
PHP comes up with an interface like Zope, so what would be better? Many
questions, isn't it ....

Any comments are welcome.

Thanks.
Nikolai

Field indexes can index any kind of picklable object value, including
DateTime objects.  This is how searching by date is done on the Zope
site.

Keep the cgi scripts in Apache, migrate to Zope at your leisure.

Zope, more correctly Python will not take advantage
of a dual processor. 
I probably seriously consider buying a ZEO solution
from DC. 
I don't know, but a ZEO solution might solve the 
problem with 100 continuous concurrent users
writing to the ZODB?

Yes it will, it just won't scale exactly two fold.  In almost all Python
wrapped C calls, the C code releases the interpeter lock as often as
possible, this allways happens, for example, when doing I/O or when
calling  database library routines.  Two processors will give you a
noticable benefit.  Four or more will probably not.

Further, Zope will not be the only process running, so a dual gives you
the usual benefits, like doing a compile on one thing without killing
your website.

ZODB FileStorage was not designed to be write intensive, the goal is to
provide a mid-write high-read solution, this solution satisfies 99.9% of
all web site needs.  You would be surprised how much money you have to
pay to Oracle to get, for example, their high write-write distributed
database solutions (its in the six figures).

ZEO is a distributed storage, but in the end it depends on a mechanism
that actual writes the data somewhere.  In the stock case, this is a
FileStorage.  If you want high-write intensity, consider a
BerkeleyStorage (which works fine as the backend for ZEO) or offload
alot of your high-write intensive data to a relational database.

The unique id problem come up again and again.

The automatically generated unique id will benefit web author with

sql row id
object id

and may be some others

With a view that zope will be run over the network with distributed storage
across the net, I would like to suggest we implement a unique id server
which can be a zope server serving on another port and serialize all request
and return the globally unique id.

Does this work?

I also suggest zope can be configured to automatically get the object id
from this service and have globally unique object ids.

As far as multiprocessing goes,  if I were to run a MySQL database on the
same server (serving primarily to Zope) then the multiprocessor config would
be a very big performance boost wouldn't it?

What about Memory?   Again with MySQL.  I suppose I should have mentioned it
right of.  Our main goal is to serve up pages from a database that will be
about 500MB-1GB in size.  There will be very little information which will
be cachable,  almost all of the queries are unique.

Does there have to be any meaning to the keys?

IOW, would a random, unique id work for you?

If so, you can take a look at:

http://www.zope.org/Members/Bill/Documentation/AutoGenID

For ways of doing it. You would insert the generated id into the SQL
table instead of the id field of a zope object.

If you are doing this inside a <dtml-in> tag, you can use the sequence-id-odd
and sequence-id-even vars, thus:

<dtml-in someSequence>
  <dtml-if sequence-id-odd>
    <tr bgcolor="blue">
  <dtml-else>
    <tr bgcolor="red">

Legacy.  python expressions were added after sequence-item.

Use the namespace object as a mapping:

I asked much the same question whilst replying to a very similar question
recently.  the -'s in the names is from times predating Python expressions
(afaik).

to access that var, use the _ namespace:

<dtml-call "foo(var=_['sequence-item'])">

Sure, I do it all the time. The following way is the fastest I came up with:

- Create a style sheet that looks like that:

// even rows
td.listrow1 {
       color:        blue;
}

// odd rows
td.listrow0 {
       color:        white;
}

Then write a DTML method/document (for example displaying objects in a folder):

<table>

<dtml-in "objectValues()">
   <tr>
       <td class="listrow&dtml-sequence-even;">
           <dtml-var title_or_id>
       </td>
    </tr>
</dtml-in>

</table>

sequence-even returns a boolean  set true (1) when we have an even row.

This is untested code, but should work.

Stephan

First, you didn't provide a traceback.  Please allways send a traceback
with an error report otherwise we can't really help you.

Second, I can't reproduce the problem you describe.  I uploaded a file
into Zope, and randomly click a dozen or so checkboxes a dozen times,
and no error ever occur when I click 'Change'.

How, _exactly_ do you get this to happen?

 Our project has a requirement to have all artifacts under source
 control (in this case ClearCase). What is more, our defect
 tracking system is intergrated into our source control system
 such that work done on defects can be traced to versions in the
 source control system. The key requirment is tracability.  Any
 work done can be traced back to when, where, how and why and
 vice versa.

 The problem is Zope. To have meaningful tracability in zope
 means have some system whereby a representation of the zodb
 exists in source control and any changes by users are
 automatically reflected in the source control. The ability for
 the source control versions to be imported back into Zope would
 be a plus.

 Any ideas?

 When building a Product using ZClasses, I often want to create
 a "root" ZClass, which the manager will create in a normal
 folder, and which will then expose the Product's other ZClasses
 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel
    +- FooProduct
       + FooItem_add_permission
       +-FooRoot
         +- FooItem
         +- FooItem_add

       + FooRoot_addForm
       + FooRoot_Factory

  Reviewed by:  Tres Seaver tseaver@palladion.com

 Hmmm, I don't seem to be doing so well on picking topics.  Here
 is what I had in mind:

  * This site is an instance of the 
    "ZGotW product":http://www.zope.org/Members/tseaver/ZGotW,
    which has a "main" factory, ZGotWRoot_factory, in its root
    folder.

  * This factory does *not* create an instance of a "folderish"
    ZClass, but rather, creates a normal Folder and populates
    it from a set of default DTML objects, along with a ZCatalog.

  * Individual issues of ZGotW are created within this folder
    as instances of the ZClass, ZGotWIssue, using the code in
    those "cloned" DTML objects.

 My rationale for adopting this approach, rather than creating
 a "folderish" ZClass, was to allow each instance of the "root"
 to be independently customized;  the "common" behavior of a
 ZGotW site is included in a set of utility methods, which can
 be tweaked to enforce different policies, or change the
 look-and-feel of a particular site.

 The downside to this choice is duplication of code:  should I
 find a bug in the original, default code, I have to then fix it
 in each instance as well as the Product.

 Comments, anyone?

Ethan,

Welcome to WorldPilot! (Note: I am not connected with the developers just a
user.)

In order to see other users names in any of the PIM areas those things must be
shared from the sharing page associated with the content type. In the Notes
section it works as follows and I assume similar for the other sections though
I haven't had time to work it through all the paces. If you have browse access
you can see public postings, if you have read access you can see public and
confidential postings. When in Notes any of the users who have shared
information that you can see will become visible. Example:
Tester1 enters 3 notes: 1 private, 1 public, 1 Confidential.
Tester2 has browseable; read access to Tester1's Notes. 
Tester3 has browseable access to Tester1's Notes. 

Both will see Tester1 as an option in the user selection under notes. Tester2
will see 2 notes and Tester3 only 1.

HTH,
Jack

Here is my take on it:

- Never have something high-volume-write to ZODB.
- Use RDBs and LocalFS or other ports to write to the File System.
- If you really need to large data in Zope format look at plugable brains, 
the idea is great.
- I noticed PCGI and Apache increases your performance, especially when you 
serve up big files.
   Setup: Apache using virtual hosts HTTP & HTTPS running Zope PCGI, for 
Images and for large files.
             My Images are served using port 81 and Documents using port 
82. That worked very well so far. We still have to test it live.
- I have two servers running: One for the DB and one for the rest: Mail, 
HTTP/HTTPS, Zope, SSH ...
- Even though not much is going on, the Web server has a constant use of 
400 MB RAM (so I would suggest 512 MB RAM)
- The DB server should be your real performance working horse. Buy a 
computer that will reflect your DB load...get a lot of memory though (1-2 GB).
- Put in both servers a dedicated NIC only for the DB info transfer.

I think that will  get you going pretty well. For the Web server Processor 
power maybe more important than for the DB server. That completely depends 
on how much you team likes SQL (meaning, how much logic is done using SQL).

Stephan

Subject: [Zope] PHP vs Zope
In-Reply-To: <38D80AF9.3FE3909F@netspace.com.mx>
Message-ID: <l03130300b4fe04b0d651@[206.221.224.184]>

In a technological sense, comparing PHP and Zope is a little bit silly,
since they are so very different.  In a practical sense, comparing them
is extremely reasonable, since there are a wide variety of web development
tasks which can be approached with either PHP or Zope.

Performance comparisons are the toughest.  PHP is no slouch -- it is used
for some very high traffic sites, including freshmeat.net and lots of
others.

Zope, on the other hand, offers some features which will cause it to
outperform stock PHP in many cases.  PHP is a scripting language for
website development.  In contrast, Zope is described as an application
server.  As such, Zope includes features like pooling of database
connections and caching of database query results.  These are not
as easy to do in technologies like PHP, and they can make a huge
difference in the performance of database-driven sites.  We
implemented www.CodeCatalog.com twice -- once in Zope, and once in
PHP.  The Zope version ended up much, much faster.  Your mileage
may vary.

I'm pretty sure it's possible to get good performance from PHP and
Zope, if your situation is appropriate and you're willing to work at
it.

I am equally sure that it's pretty easy to get lousy performance from
either PHP or Zope, if your situation is especially inappropriate, and
you're willing to live entirely off the low hanging fruit.

There are lots of other comparisons which could be made, and have been
made.  These comparisons tend to degenerate into flamewars pretty quickly,
although I see no reason for this to happen.  Objective comparisons
of two technologies like this are useful.  I happen to like both, although
Zope certainly gets an increasing share of my attention.

Zope's three-tiered architecture and web-based authoring tends to make
the tool more approachable by people who may be less technical, and
more annoying to hardcore programmers who find they have a new paradigm
to learn.  The gap between the experiences of these two groups of
people tends to narrow very quickly as people start to grasp the soul
of what Zope is all about.  People who are learning Zope tend to
periodically burst out of their office with a desperate need to
tell someone about the latest core principle of Zope which they finally
came to understand.  The more you have these "light bulb" experiences,
the cooler Zope is.

PHP isn't like that.  It's an excellent tool, but it's really just
a scripting language.  It isn't everything that Zope is, and it
doesn't try to be.

Compare PHP to Python

Compare Zope to Midgard.

BTW, the safest way to do those comparisons is *probably* to do them
somewhere other than on this mailing list.  :-)

Subject: [Zope] Zope : Load_site features request
Message-ID: <000501bf93cd$87f93c20$770da8c0@bbs>

Load_site is a greate product.

I am using it to upload a brunch of files to zope now, I found I have an
idea :

In order to make the uploaded zope more alive, I would like the load_site to
make everyfile in the original archive an folder in zope, with index.html
representing the structure of the original html file. And all the contents
goes to obj1, obj2, .... reside on the same folder. For example,

Index_html :

<dtml-var standard_header>
<body><p><dtml-var object1></p><table><tr><td><dtml-var
object2></tr></td></table>
</body>
<dtml-var standard_footer>

This would make the resulting zope site more close to the zen of Zope.

I am not very good in python but please give me some hints to made this
modification. Will you make the change?

Rgs,

Kent Sin

Message-ID: <38D87A4A.FFBE3FF4@fr.bosch.de>

Hi Zopistas

while trying to make gtk's (very useful) Boring Product (slightly
more) interesting, I came across the following (for me) strange
behaviour.

manage_ methods seem to always have "REQUEST=None" as their last
parameter. If I remove the "=None" from manage_edit then I notice no
difference, so the actual parameter is presumably being passed.
However if remove the complete formal parameter (and the reference to
REQUEST in the body of the method) 

def manage_edit(self, title): 
        """does this really need a doc string?"""
        self.title = title
#	if REQUEST is not None:
#	    return MessageDialog(
#		title = 'Edited',
#		message = "Properties for %s changed." % self.id,
#		action = './manage_main',
#		)


then everything still works ! Why is python not complaining about a
parameter mismatch ?

I promise to publish a Howto on making Boring more Interesting when
this madness is  over.

Thanks in advance

Thanks. That is the current work-around that I am using...
(Key derived from a time-stamp with millisecond precision.)
There is one observation and two problems:

(1) ZopeTime is not as good as the getdate() function
    from Sybase, if you are running multiple Zope
    webservers (for load-balancing.) That is, it's
    better to rely on one unique source of timer.

(2) There is a slight chance of two processes getting
    the same key, if they happen to occur within one
    millisecond of each other. The probability is small,
    but unfortunately I have to address even this minuscule
    probability. :(

(3) If the server's time is re-adjusted for any reason,
    it's possible that some keys are regenerated.

I agree that the millisecond-precision key is really good
for non-critical applications. But because of the nature of
our project, we need to address even the slightest chance
of error. :(

I think I will adapt the Sybase's recommended stored procedure
to Zope, by using DTML and ZSQL methods. It's kind of nasty
for something as simple as a surrogate key generation, but it
seems more secure.

thanks again,

Hung Jung

hmm, i must admit that I still can't get it to work with simple 
numbers. I have a field with the number "20002" but it doesn't matter 
wether i use text or field index it still don't work. Am I forgetting 
something ?? And yes - I reindex the cataloge before searching.


But I will look into the date thing right now!!!

Because Zope passes in those parameters that the method asks for. If you take
away the REQUEST parameter, Zope simply doesn't pass it in.

The manage_ methods use REQUEST=None to make sure you can use the methods in
situations there is no REQUEST to pass in. You can call manage_edit with a new
title, and have it still work, from a DTML Method without having to pass in
the REQUEST object, as you won't need the MessageDialog anyway.

Hi.

I am wondering if I can do a search/replace in the ZODB
for e.g. every DTML Document (just like search, but with a replace-with field)?
Is there anything planned or under development?
This would be rather useful to easily use Acquisition
with content imported from HTML files.
Someone could replace a menubar (which appears in all files the same)
just with the <dtml-var ...> call and create a DTML method
which holds this content.

CYa,

I think this is my point exactly ;-)

It all seems really inconsistent and I was wondering if anyone could say exactly what the 'rules'
were and why?

Interesting topic!

How does Zope compare with Midgard?
Which one is more flexible (that is: which one can be used in a wider set of
cases)?
Which one is easier to learn for the webmaster?
Which one is better fit to develop and maintain a complex web site (let's
say: 10,000 documents and 50,000 pictures, updated weekly)?
Which one is better for web sites that uses database and/or a "fragmented
document" architecure (XML/SGML documents that are disassembled and
re-assembled on demand)?
Which one can better integrate other technologies (web-mail interfaces and
so on)?
Which one is easier to use for a remote customer, enabled to develop and
maintain his pages on the server?
Which one is better for "workgroup" intranet servers?
Which one is safer (more anti-hacker)?
Which features does Zope have that Midgard does not have?

Thanks.

PS What does "Midgard" mean (I'm italian...)?

stephan, 

i agree on apache increasing your performance when serving static
files (for instance images), but wouldn't url rewriting and the proxy

PCGI to the Rewrite/Proxypass combo because of the additional overhead
of PCGI. 

(see http://www.zope.org/Members/anser/apache_zserver/ for the kind of

Mmmhh, I have to have a look. Okay, I just read the the little tutorial. 
Does it really speed things up?
I guess SSL should not be hard using this solution. I will be thinking 
about it.

Anyone else?

Subject: [Zope] Upload files in Zope and store elsewhere
Message-ID: <38D8B1FC.CCDA0827@funcom.com>

After some helpful advice, I have been successful in uploading files
(images) to Zope. Now I am trying to stuff the uploaded images in a
MySQL database, but am not able to access the image data.

If I try to stuff the image data "raw" into the database by declaring a
image:string parameter to the ZSQL Method and  <dtml-sqlvar image> in
the ZSQL code I get a string like "<ZPublisher.HTTPRequest.FileUpload
instance at 87956214>".

Another approach I have tried was <dtml-var image fmt=sql-quote>, but
this complains about the image being an instance and not a string.

Another approach has been to access the actual "raw" image data using
image.data in various combinations, but I have not gotten this to work
anywhere (contrary to what it seems other people have managed to do),
see this 

http://www.egroups.com/group/zope/26227.html?

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

Marius Kjeldahl

Hm, I _think_ I recall (but I can't test this right now) that the ZSQL
method will only accept values that are given explicitly in its
arguments and in that case it will also acquire them. That would make
sense from a security point of view.
Or perhaps it was a bit more complicated - I have to investigate this

some testing with apache benchmark:

the setup is an apache 1.3.12 sitting on port 1988.

/tstfolder/bmeth is a very simple dtml method ("i am bmeth in
/tstfolder" <dtml-call "REQUEST.set('testvar', 'hm...')">
&dtml-testvar;). 

i do 1000 requests at 50 concurrent users, keepalive-connection via
apache benchmark:

first the result of doing a proxypass to zserver on port 8080:

   --------------------


conclusion: with proxy pass i get around 30% more requests per second
and around 25% less connection time (and im not able to use keep-alive
as it seems).

please note that this is only a quick check and not scientific in any
way, and naturally the benefits will diminish when more complicated
pages are going to be served.

if there are any other test results please let me know...

peter.

Hello Marius,

TI am a Newbie to Zope and this is the first time I post a Answer to the
mailing list. But I had the same problem and I hope I can help you.

After a lot of test I find out the following method to upload images to
MySQL and after that retrieve it in the web pages.

Write the folliwing ZSQL method:

       Arguments: N_
                  Titulo
                  Subtitulo
                  Texto
                  Foto

      insert into Novedad
        (N_, Titulo, Subtitulo, Texto, Foto)
      values (
        <dtml-sqlvar N_ type=string>,
        <dtml-sqlvar Titulo type=string>,
        <dtml-sqlvar Subtitulo type=string>,
        <dtml-sqlvar Texto type=string>,
        <dtml-sqlvar
"_.string.replace(REQUEST['Foto'].read(),'\010','\\010')" type=string>
      )

Note that I replace the octal char 010 by the string "\\010".
If you don´t escaape this char MySQL change it for the char 008. I don't
know why.
To upload the image I have the following DTML Method:

<form action="novedades" method="post" ENCTYPE="multipart/form-data">
  <input type="hidden" name="accion" value="insertar_novedad">
  Nş producto: <select name="N_">
    <dtml-in listar_N__producto>
      <option value="<dtml-var N_>"><dtml-var N_></option>
    </dtml-in>
  </select><p>
  Título: <textarea rows="2" cols="20" name="Titulo"></textarea><p>
  Subtítulo: <textarea rows="2" cols="20" name="Subtitulo"></textarea><p>
  Texto: <textarea rows="8" cols="40" name="Texto"></textarea><p>
  Foto: <input type="file" name="Foto"><p>
  <input type="submit" name="submit">
</form>

Note the the line "Foto: <input type=....".
And to retrieve the image I have this DTML Method:

Method name: image

    <dtml-in obtener_foto>
    <dtml-call "RESPONSE.setHeader('Content-Type', 'image/gif')">
    <dtml-call "RESPONSE.setHeader('Content-Length', _.len(Foto))">
    <dtml-var "_.string.replace(Foto,'\\010','\010')">
    </dtml-in>

Note that you must put the 5 lines in the same line (without newlines).

ZSQL Method name "obtener_foto":

      Arguments: N_

      select Foto
      from Novedad
      where
      <dtml-sqltest N_ type=string>

To insert the image in an dtml method:

<img src="image?N_=AC-M56E">

Hope this can help you.

Excellent, just what I was looking for. 

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

and this to anyone who wants to answer: ;-)

   Anyone know why? This is a little disturbing...

Subject: [Zope] Q: <dtml-in sort=twofields>
Message-ID: <E12XlPG-0002fb-00@home.delysid.org>

Hi.

I am constructing a search interface for a catalog.
The objects I index have three relevant properties:
title (textual title)
id (the id, sortable)
book_title (the name of the book where the chapter is included)

I want to have atabular result like this:

Book 1     Chapter 1.1
           Chapter 2.1
Book 2     Chapter 1.1
           Chapter 4.2


To acomplish this I currently do something like:

<dtml-in Catalog sort=id>
  <tr>
   <td><dtml-if first-book_title><dtml-var book_title></dtml-if></td>
   <td><dtml-var title></td>
  </tr>
</dtml-in>

But, to have the list look nice, I'd need to specify
two fields for sorting, book_title should be the primary
field sorted by, and id should be the field all identical
book_title entries should be sorted on.

Is there a way to do this with dtml-in?

CYa,
    Mario <mlang@delysid.org>

here you are! (see end of post)(i hope you dont mind my adressing

btw. does anybody know of other benchmarking software? (i once tried
to grab httperf but the ftp site holding the source is down...)

So ProxyPass is 20 % faster. Cool. I will try that.

Subject: [Zope] Names containing colons?
Message-ID: <200003221420.IAA08813@beluga.mojam.com>

In my web page input forms I've been using field names like "radius:int" so
Zope will coerce variables to the proper type.  This works fine on the
server.  Unfortunately, if I have a JavaScript function on my web page to do
form input validation, how do I reference that object?  Is there some
alternate naming scheme that will allow Zope to do the type cast and allow
references from JavaScript?  Should I just forego the :int stuff altogether
and do the coercion explicitly?

Thx,

In your JavaScript functions, reference the variable as such:

forms[0].elements["radius:int"]

(Replace the "0" with an actual name if you've named your form . . .)

If a "folderish" ZClass had some way to expose its customizable parts, so
that you could go to an instance and say "instantiate a local copy of method

Excellent, just what I was looking for.

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

It's BLOB

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

< 1MB

and this to anyone who wants to answer: ;-)

   Anyone know why? This is a little disturbing...

From Python (either an ExternalMethod or a product)::

  import sys, os, string

  def ExecCGI( cmdLine ):
      """
      Run an external command and return its standard output as a string.
      """
      f = os.popen( cmdLine ) # note that Win32 has a non-standard popen()
      lines = f.readlines()
      status = f.close()
      if status:
         raise "CGI returned error: %d" % status[1]
      return string.join( lines )

To call it from DTML, passing the current values of 'foo' and 'bar'::

   <dtml-let cmdLine="'/path/to/my/cgi %s %s' % ( foo, bar )">
     <dtml-var "ExecCGI( cmdLine )">

I am happily using CodeIt.  They offer several options above "basic" Zope
hosting:

  * Install your own products (this is their "professional" option).

  * Add disk space cheaply (they quoted me $0.50/month for each added 10 Mb).

  * Add domains, mapping them to separate Zope folders, for $10/mo each.

> Shell access is welcome, too..

They don't offer shell access -- I FTP products, export files, etc., into a
"home directory" with a slightly oddball layout.

Zope wants to be a long-running process, with significant CPU and RAM
requirements;  most ISPs don't appreciate you running such a beast, so ask
first.

Message-ID: <Pine.BSF.4.21.0003221005110.8916-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday before Noon.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * Two new Zope revisions were released this week.  2.1.5 filled in
    security holes which affected sites which allow untrusted users to
    create DTML documents.  Ironically, a bug-fix which was included
    in 2.1.5 broke code which depended on the bug.  This was fixed in
    the second release, 2.1.6.

    http://www.zope.org/Products/Zope/2.1.5/Zope_215_release
    http://www.zope.org/Products/Zope/2.1.6/Zope_216_release

  * Thanks to Eduardo Fernandez Corrales, the Zope Weekly News is now
    available in Spanish!  He is publishing translations at Zope
    Hispano, a portal for Spanish-speaking Zope developers and users.

    http://zope.sistelnet.es

  * Healtheon | WebMD is hiring in Atlanta, GA

    Healtheon | WebMD is looking for Software Engineers with
    experience in Python and/or Zope to work in our Global News Center
    located in Midtown Atlanta, GA. You must be willing to relocate.

    http://www.zope.org/Members/kbirch-webmd/hiring-notice


New Products

  * The Portal Toolkit has been packaged into a snapshot release for
    use by those who do not have access to CVS.  The PTK is targeted
    at community-oriented portals, but is also appropriate for any
    site which wants to give members a personalised view of content.
    The snapshot release is 0.7.1.

    http://www.zope.org/Products/PTK


Updates

  * Software Product: load_site.py with additional features, by Itamar
    Shtull-Trauring

    Itamar has updated his powered-up 'load_site.py' again.  The
    present release is 1.3.1.  This update adds a GUI, built with
    wxPython.  'load_site' is a utility for dumping content from a
    file system into the ZODB.

    http://www.zope.org/Members/itamar/load_site

  * Software Product: ZopeEDIT, by "jimbag"

    The latest release of this product, 0.0.5, adds limited RPC
    support which is used to create and delete folders.  ZopeEDIT is a
    tool which enables any text editor to edit content on a live Zope
    server.  It does not need to run on the same machine as the Zope
    server.

    http://www.zope.org/Members/jimbag/ZopeEDIT/

  * Software Product: LocalFS, by Jonothan Farr

    Version 0.1.6, the Ides of March release, fixes several bugs, is
    more robust about determining file types, and creates XMLDocuments
    and StructuredDocuments automatically, where appropriate.  LocalFS
    is a product which allows Zope to serve files out of a local
    filesystem.

    http://lists.zope.org/pipermail/zope-announce/2000-March/000130.html

  * Software Product: SiteAccess, by Evan Simpson

    Evan has release version 1.0.1 of SiteAccess.  This version fixes
    a bug which interfered with FTP access to Zope.  The SiteAccess
    product allows Zope to serve different content depending on the
    hostname the site was accessed by.

    http://www.zope.org/Members/4am/SiteAccess

Zope.org items

  * How-To: VersionFTPServer, by "htrd"

    This How-To describes modifications to Zope which allow you to
    work within a Version through FTP.  Versions allow you to stage
    changes to a Zope site by effectively forking the database.
    Changes that you make in a Version are not publicly visible until
    you ask them to be.

    http://www.zope.org/Members/htrd/howto/VersionFTPServer

  * How-To: How To: Use GenericUserFolder with an SQL database Version
    1.1, by "hippy"

    This How-To shows how to customise GenericUserFolder(GUF) to use
    an SQL database as its repository for usernames, passwords, roles
    and anything else you want to store about a user.  The update adds
    information from Dennis Baker to help get things going with MySQL.

Midgard is a PHP and MYSQL integration.  Midgard uses MySQL the way Zope
uses ZODB, as well as relying on MySQL for the things that Zope can use
other databases for.  I would assume that Midgard is a logical step for
those coders that are used to making database-driven dynamic web pages
with scripting languages, and is probably intimidating to those that
don't come from that background.

On a brief overview, Midgard seems to want to exert more control over
your approach to content.

[snip questions I can't answer]

> Which features does Zope have that Midgard does not have?

Well... Zope is object oriented, transactional, can interface with a
variety of databases, uses and is written almost entirely in python. 
The web-management seems more robust, but I could be out to lunch.

> PS What does "Midgard" mean (I'm italian...)?

Midgard (should be Midgaard or Midgĺrd) is the Norse word for the
material plane, as opposed to Asgĺrd (the realm of the gods).

but be careful, since this is a security hole.  the executed command line

Hi,

The company I work for is getting into Zope hosting.
We're based in the UK and are pretty open minded since we've started doing a fair bit of work in
Zope ourselves.

If you or anyone else is interested in European Zope Hosting with a flexible, open-minded ISP (of
course, I would say that ;-) then contact 
Simon Coles (simon@nipltd.com) or myself.

Hope this helps,

Chris

I messed around with this a little bit before giving up, though I'd like it to
work....

The problem (as I see it), is that 1) you have to get to the data and 2) you
have to format the data properly so that the database stores it properly.  What
I've gleaned is that the binary data will contain characters that confuse
whatever DA you're using (I use the ODBC adapter).  This means you'll probably
have to replace these 'confusing' characters with their 'safe' counterparts.
For the person who got it to work, it was the 0x08 character.  I believe other
DB's will choke elsewhere.  I never could figure out which characters needed
replacing and with what, so I wrote an external method to save the file and just
wrote the filename/location/upload info into the database.

This wasn't as nice as I wanted (I had security concerns putting anyone's files
on the hard drive), but it will probably work (I get sidetracked once I got the
file saved and haven't finished that project).

Let me know if you get it solved (I'm using ODBC to a cheap acess database).

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

Marius Kjeldahl

Zope on Python and not other language?

I use Rackspace.com which is certainly not as cheap as other hosting
providers but for under $200 you can get a fully dedicated 350 MHz, 64MB
RAM, 8 GB HD and RH 6.1. So, in the end you pay about 2 to 3 times what
another hosting provider has but it is your machine. You can install
whatever you please, configure it to your hearts content and never have to
worry about what someone else will say. Zope loves its own machine.

I have found their support to be great and they do a 24 hr turn around for
new accounts.

Worth every penny (twice the penny if it is for your company).

I think the best analogy is to think of ZSQLMethods, ExternalMethods, and
PythonMethods like "normal" functions in C:  they receive information via
arguments, and acquisition is always done via one of the explicitly-passed
arguments.  DTMLMethods/Documents are in some ways more like C macros:  they
grab information from the surrounding DTML context, without having to be told
what they can "see".

The analogy breaks down at the "call site":  Zope looks at the explicit
parameter lists and tries hard to match arguments to any parameters which are
not explicitly passed by the caller:  normally, it does this by looking them up
in the REQUEST object, *not* in the current DTML namespace.  Therefore, whenever
calling a non-DTML method (External/Python/ZSQL/...):

  * poke all interesting values into the REQUEST object before calling::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-call "REQUEST.update( { 'bar' : 42, 'baz' : 3.1415926 } )">
     <dtml-var foo>

    This version has the advantage of avoiding the "expression" syntax
    of DTML, but does require polluting the REQUEST namespace (may be
    an actual advantage if multiple methods use the same values).

  * pass the values explicitly, using positional arguments::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( 42, 3.1415926 )">

    This version looks most "natural" to a programmer, but is fragile WRT
    changes in the parameter list (changing the order of parameters on the
    method silently breaks this call).

  * pass the values explicitly, using keyword arguments for clarity::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( bar=42, baz=3.1415926 )">

    This version, which I prefer for any method taking more than one argument,
    says explicitly what it is doing, and therefore eases maintenance.

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985FA@pces.cadlab.it>

Python is quite slanted toward this kind of applications:
1) very clear sintax (many webmasters are not particularly fond of C and
Perl, like me...)
2) strong support for string management and a very good regular expressions
module
3) wide choice of modules for interfacing with web servers, mail servers,
database, etc...
4) ready-to-use modules for HMTL, Mail messages and XML manipulation
5) tons of good documentation, examples and a very active community
6) hard-rock core system and reliable modules
7) indipendence from the platform (Python runs almost everywhere. I'm
re-compiling it for my Z80-based microwave oven...;-)

Despite this, I think that the real reason why they decided to use python
was the terror to commit a mortal sin (like touching a Perl interpreter) and
the desire to live immersed in the light of the true Faith. 

I would have done the same...

This is great, some light at the end of a very dark tunnel.  One
question here:

How where you able to get strace to work?  I've been trying and it
either would lock Zope up or just return instantly.

Yes, we noticed that to.

Is this only when accessing via FastCGI or does happen when using
ZServer as well?

Thanks for the info.  If we find anything out I'll let you know.

My advice here is not based on work with Zope, but on years of painful RDBMS
experience:  I do *not* recommend storing large BLOBs in any existing RDBMS --
they aren't built for them, and generally make your life miserable when you
try.  Most of the reasons you would choose to use an RDBMS (performance,
replication, stability, searchability, etc.) don't apply when it comes to large
BLOBs;  you are still much better off storing the "BLOB" in a filesystem
somewhere, and then storing a path/URL to it in the RDBMS.

With Zope, BLOBs present another issue:  because they aren't standardized, each
RDBMS has a proprietary API for BLOBS;  the Zope database adapter therefore has
to have custom code for each RDBMS, making the BLOB code one of the likeliest
sources of weird, hard-to-reproduce bugs I can think of.

In short, *don't go there*.  Really, I'm serious.

Tres.

P.S.  If you *have* to go there, use the Python base64 module to encode
      binary data.

No such decision was ever made. When Paul Everitt and Rob Page founded Digital
Creations (a history I know only from Paul's and Rob's telling me, I could
well be out for lunch on this), Paul was getting quite heavily into Python
already. He convinced Rob that it might be a good language to base their
development on.

They then hired Jim Fulton, then already a very active Python contributor (he
hosted, if IIRC, the 3rd and/or 4th python conference or something). Under his
technical guidance software was developed that only in November/December 1998
came together to form Zope.

Many parts of what is now Zope, like Bobo (predecessor of the ZODB), DTML
Templates, Extension Classes and Acquisition where already Open Source, and
heavily used by the python community. When Zope came to be, all those parts
were mixed with things like Acquaduct (now database adapters and ZSQL
Methods), and Principia (now the web management interface and many of the
stock Zope objects like File and Folder), that were commercially sold by
Digital Creations.

So, python made Zope and its power possible. If you now decide that you want
to go and build Zope in a different language, you will first have to try and
build all those parts from which Zope came to be. And this will be pretty
hard, if not impossible. Pythons clarity, OO orientation, extensibility and
last but not least Jim's technical excellence with python will be greatly
missing.

I think it had to more with Jim Fulton's "zealos object-orientedness" than
that -  Zope is a system for publishing python objects on the Web.

I suggest that you negotiate with service provided over the terms of the
service agreements. You might find that they are more flexible than their
web pages indicate. Or you may influence them to change the standard service
agreements. I use CodeIt Computing and am happy with their service.

The implementation I sketched out a version of the Prototype pattern, I think. 
Exposing the customizable bits is more like a TemplateMethod:  this would play
nicely with Acquisition, perhaps::

  <!-- Inside the index_html method of a "folderish" ZClass -->
  <dtml-if custom_foo>
    <dtml-var custom_foo>
  <dtml-else>
    <dtml-var default_foo>
  </dtml-if>

The trick then becomes giving the manager enough information to know how to
implement 'custom_foo'.  My current hack solves this by cloning the default bit
as a starting point -- perhaps the factory could clone 'default_foo' as
'sample_custom_foo', or something?

Message-ID: <Pine.OSF.4.02.10003211815310.20006-100000@batman.tamucc.edu>

Based on previous e-mails here, I have read that Zope does not support
server-side includes.  Is there a way to get around this in reference to
an img src, as in the following:

<img src="myprogram?-action=gif&amp;yadda yadda yadda>


Basically what I have here is a page that includes other documents (maps,
graphs, etc.) via server-side-includes.  If there isn't any way around
this, then I may have to forgo Zope for now...too much of my system
depends on this sort of thing.

Thansk in Advance,

This has to do with Amos's article on using XMLDocument at xml.com:

The example for finding items to catalog doesn't work for me.  When I enter
getNodeName()=='entry' in the 'expr' field I get the following error:
 Error Type: NameError
 Error Value: Eval

I'm running Debian GNU/Linux (frozen), Zope 2.1.4, Zcatalog 1.0.0 and

Message-ID: <B059671903C6D211A0D500C0F0301C792B2714@kubrick.mop.no>

Adding a SiteRoot object to some folder upward from a ZDConfera topic
("Confera Topic" object) will break the topic.

It seems that when adding a message, instead of inserting a valid
message object, ZDConfera ends up adding a corrupt object. At one point
ZDConfera, when I tried adding a follow-up, duplicated the parent
message instead of adding the reply, resulting in a circular reference
that only a database restore would fix.

This is Zope 2.1.4, SiteAccess 1.0.1, ZDiscussions 0.2.0, on Slackware
Linux 2.2.

Here's the traceback.

I would like to know why the following happens, and what I can do to fix
it:

I have a ZCatalog instance in my root folder called Catalog. I have some
CatalogAware ZClasses that get added to it automatically.

The problem is, when I query Catalog for results, it only shows the
elements that were present the last time I clicked the "Update" button in
ZCatalog. The new elements are present in the catalog, but they don't show
up in the query until I manually update the catalog.

Here's the query code:


<dtml-in "Catalog(meta_type='Track', track_hasfile='on',
track_active='')">
  <li>
  <a href="<dtml-var "Catalog.getpath(data_record_id_)">/approve">
  <dtml-var "Catalog.getpath(data_record_id_)"></a>
</dtml-in>

Any help appreciated. Please CC me if you answer.

Here's the scenario that I'm dealing with (all of this works w/o Zope,
i.e. static content):

  - user starts at www.mydomain.edu (http)
  - user goes to www.mydomain.edu/internal which is secure (https) and
    requires a password for entry
  - all pages under www.mydomain.edu/internal are secure (https)

I'm having trouble getting this to work with out Zope-ified site, however.
What I would like is to have Apache handle all password authentication, and
I would like it to happen over ssl.  Is this possible at all?

Any help would be appreciated.

Thanks in advance,

Just a few thoughts.

Simple workaround: make the id field unique. it would seem to me that
you could then use a try/except clause that tried to insert the data
into sybase, and redreate an id if it failed due to the id already
existing.

Additional options:
 o add a randomly selected letter (or two) to the numerical id. Now the
odds that any two servers, or a change in time, will obtain the same key
are extremely slim.
 o Randomize the order of numbers in the 'timestamp'

Combine these with the unique restriction above, and you should have a
_very_ scaleable, an relatively easy to implement, solution.

Subject: [Zope] Casting to a list
Message-ID: <38D91168.F163496@messagemedia.com>

Another question (soon I'll start answering more on this list :) - I
have a set of checkboxes with the same name that I iterate through
using dtml-in. However, when only one checkbox is checked, dtml-in
complains that a string cannot be used as input, it expects a
sequence. My initial thought was to do this:

<dtml-if "type(var) == type('')">
  ... (do not iterate)
<dtml-else>
  <dtml-in var>
    ...
  </dtml-in>
</dtml-if>

How can I either cast a string to a list w/o messing up an existing
list, or gain access to Python functions such as type() from a
dtml-if statement?

Zope in a sense replaces server-side includes with <dtml-var>.

What you need to do is upload the images to Zope in whatever folder
is appropriate. To do this, select "Image" from the create item menu
found at the bottom of your Zope "Contents" screen. Select the images
you would like to upload, and submit.

The images will then be in your object hierarchy.

You can reference them using either
  (1) Manual <img src="...">
  (2) Using dtml-var (the Zope way of doing things)

Say, for example, you uploaded an image called foo_jpg (Zope does not
allow dots in object names). You could reference it from any object in
the same folder as the image or nested folders using dtml-var

	<dtml-var foo_jpg>

Zope will automatically insert the height and width attributes and so
forth. To remove the border, you would use...

	<dtml-var "foo.jpg.tags(border=0)">

(I think)...

There are some interesting HOWTO's on this topic at zope.org.

I quess Zope is more "object-oriented" as it is based on an OO language.

OTOH, said OO language itself has been implemented in OO and non-OO 
languages (java and C) ;)

Probably the less flexible one ;) I don't know which.

There is currently a 2 Gig native (Zope internal) database size limit. 
This won't apply when you use external database or sore files in file system.

Bot are wll supported on Zope. Dunno about Midgard.

Zope has integrated a lot, so does PHP - you probably find most popular 
"other technologies" supported/supportable on both.

Probably Zope (this is a Zope list)

The one you know better :-p

I guess they are about the same. The one that will be used more will 
eventually be safer due to more eyballing.

Both can be configured to be insecure ;)

Howdy everybody.  Last night at the Bay Area Linux Users Group meeting I
announced that we are going to make ZEO Open Source and thus a
first-class feature of the Zope platform.  For more information:

  http://www.zope.org/Products/ZEO/

Some quick notes:

  o A first release for a very small, qualified group of testers will
happen mid-April

  o General release some weeks after that

ZEO (Zope Enterprise Option) turns Zope into a *distributed*
transactional object system, allowing people to add processors,
machines, and networks to scale their web applications.

It looks like Proxy Pass is the best way to go.  Can you use Proxy Pass with
SSL?  ZServer alone is not a choice because SSL is a requirement.

You know after reading this thread I was pretty surprised that we didn't
have simply execcgi ability in Zope, considering how trivial it is.

I'll look into something like this possibly being a feature.

It sounds like this is probably coming from an SQL database? If it is
modify the query you're using to sort on the DBML-side. If your
query looked like:

	select * from books

You would modify it. Having mutliple levels of order by varies from
DBMS to DBMS, but it'll look something like this:

	select * from books order by book_name, id

Or something to that effect.

Sorting using the DBMS is more desirable as well because the DBMS
is likely to sort it more quickly, with all its indicies and so
forth.

If you tell me which DBMS you're using, I probably know exactly
what you should do to your query.

Ihis didn't work, then?  Looks better than what I came up with, which, for the
list vs. string situation goes like:

<dtml-try>
  <dtml-in string_or_list_var>
   list stuff...
  </dtml-in>
<dtml-except>
  non-list stuff...
</dtml-try>

If you have a string with multiple values to split, use the _.string.split()
function, as...

<dtml-in "_.string.split(str [,separator])">

This will probably choke on lists, though.  Combine the two for a wholesome,
good-start-to-your day breakfast code. :-)

This is less of a Zope issue and more of a DBMS issue (which is why I
can answer it)...

There are two ways to get global unique ID's:
  - Have a unique ID server
  - Find a way two servers can come up with ID's unique to each other
    without talking to each other. This is a lot of fun, and is done
    by using the network card's ID number, which is statistically
    unique. Basically, if you use the computer's network card ID, you
    can generate statistically unique ID's (this, incidentally, is the
    MS SQL Server way[*])

[*] I in now way indorse MS SQL Server. Please do not flame me for
mentioning it; I know it's a peice of crap. :)

The former is more elegant, but the latter is sometimes more practical
for distributed systems. At any rate, there is no simple solution to
this problem (many companies have had major research into this area
with little results). Your best bet is to keep this out of Zope and
just set up a unique ID server.

Have your databases (Sybase?) establish foreign links to the unique ID
server. Then, write triggers that grab ID's when rows are insert. Say
you had two tables, on two servers, that need to have unique ID's.
You would omit their ID fields upon doing an insertion, making them
NULL. You would write a trigger on insertion for these tables that
would detect the NULL id field, grab the unique ID from the unique ID
server, and insert the row with the unique ID.

In very large environments with lots of data importing, this can be
a large strain on the network and the unique ID server. If this is
the case, be sure to have good bandwidth between the servers. And
as always, bigger servers means more performance. :)

The simple answer is: you don't need to cast. :)

Zope provides a solution: your specify in your multiple-select
a name like varname:list, and Zope will automatically cast it
into a list. That is, append the ':list' to your variable names.

Thank you for your input..I think I need to explain myself a little
better, however.  I have no trouble with a static image...the trouble I am
having is with images created on the fly.


For example, I have a cgi program (which I would like to continue residing
in my linux structure.....static pages I would like to be in
my Zope structure).  This program will generate a graph based
on the time units, and whatever particular data sets I pass as parameters
to the program.  So, the image can't be stored on  Zope, since the image
may be different each time it is brought up...for example, I have the
ability to pass the word "today" as a parameter...this means that
everyday, the graph generated will be different.  Is there a way for
Zope to respond to a cgi program that's being called as "img src" value?


Thanks,
Jessica

My understanding from a recent discussion was that it happens on all platforms 
with 32-bit ints regardless of weather they support large files or not.

does ZDB use longs internally and just some small part strangles it to 32-bit,
or is it something more widespread ?

Message-ID: <B059671903C6D211A0D500C0F0301C792B271A@kubrick.mop.no>

I use identity columns with Sybase -- the only problem I've experienced
is a tendency to occasionally "burn" ID values, resulting in gaps.

If you're not worried about non-sequentiality, identity columns are
generally not a problem. Do you anticipate crashes? I have run Sybase
for about a year, and never experienced a single crash -- meanwhile,
Zope has crashed and/or been restarted many, many times.

Aside for identity columns, here's an alternative scheme I used some
time ago with an  Access database (where, aside from DAO/ADO, you simply
cannot obtain the previously inserted "autoincrement" value, causing
problems for web-based forms): Create a table such as this

	create table Ids
	(
	  Id int
	    not null
	    primary key nonclustered
	)

Then create either a stored procedure (don't like 'em) or a Zope DTML
Method that will (a) get the lowest available ID, and (b) if the table
is getting empty (count < delta), then replenish the table with new,
unique values, starting at the ID you just obtained. (If the table is
empty when you start out, assume this is the first time the method is
run, and simply start with a seed of, say, 1.)

Because of transaction logic, IDs will never be "burned", and the only
gaps you will experience will come from IDs that disappear when their
parent records are deleted.

Hope this helps.

Hi there,

I'm trying to connect to an Oracle 7.3 database through Zope using a 'Z
ODBC Database Connection'.
It's giving me an error saying:
'Invalid connection string: gsmInfo'

I set up a DSN throught the Control Panel as follows:

Data Source Name: gsmInfo
SQL* Net Connect String: 2:
UserId: testowner

This is using the 'Oracle73 Ver 2.5' Driver.

I also used the '32-bit ODBC TEST' that comes with Oracle and this
connected to the database no problem after entering in a password.

Has anyone got any clues or suggestions to the problem.

Thanks in advance,

Michael Gannon.

So, you have a CGI script that dynamically creates an image as its
output. You'll either need to re-implement this using Python and make
a ZOPE product, wrap it using a Zope product (which seems the least
elegant), or just keep it out of Zope (probably the desirable). I
assume you're running apache and using Zope.cgi, so your Zope path
is

	http://yourhostname/Zope

Now, your CGI scripts are under:

You'll just want to reference the images just like you would in
normal HTML. Zope will not mess with an img tag, so if it points
to a working CGI script, you're ok.

Does that answer your question?

Subject: [Zope] Role weirdness
Message-ID: <m3em92zrw9.fsf@wacko.pdx.net>

I have a site containing some content users need to register to see.
The way I set this up was:

/premium/acl_users[GUF]
Using GUF to authenticate and assign users a role of
contentSubscriber.

At one point in time, I created a user defined role at the root level
of my Zope called contentSubscriber.

I then changed the security on /premium to require contentSubscriber
role to view or access content information.

Now, I can't seem to find any mention of a contentSubscriber role
anywhere in my Zope management screens OTHER than by looking at a user
through /premium/acl_users/userList.

None of the Find/Advanced... screens mention my contentSubscriber role
either.

The odd thing is that my access control scheme appears to work.  Other
than my random hourly crashes.

That doesn't look like a valid connection string. Usually, the connect
string is something like:

        user/password@sid

At least using the normal Oracle interface. SID, which I assume would
map to ODBC would be the datasource name defined in your tnsnames.ora
file.

You might try testowner/password@gsmInfo

Or consult your ODBC docs on proper connect strings.

Sure.  I'm using mod_ssl and apache 1.3.12:
My conf is like this:

<VirtualHost 216.17.170.666:80>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
</VirtualHost>
<VirtualHost 216.17.170.666:443>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
   ServerName imeme.net
   ServerAdmin mindlace@imeme.net
   ErrorLog /path/to/apache/logs/error_log
   TransferLog /path/to/apache/logs/access_log
   SSLEngine on
   SSLCertificateFile /path/to/apache/conf/ssl.crt/server.crt
   SSLCertificateKeyFile /path/to/apache/conf/ssl.key/server.key
</VirtualHost>

I have zope actually running standalone on port 6666.  Then I use
SiteAccess.
The access rule should look like this for you:

look for internal, then munge the result to be 0 if not found:
<dtml-if "1+(_.string.find(PATH_INFO, 'internal'))">
  <dtml-call "REQUEST.set('SiteRootBASE','https://www.mydomain.edu')">
<dtml-else>
  <dtml-call "REQUEST.set('SiteRootBASE','http://www.mydomain.edu')">
</dtml-if>

then you want to put a SiteRoot object in your root folder, leaving
everything as per default.

As long as your first links to /internal are written as https:// the
austhentification should be over ssl. The access rule makes sure any
dynamically generated URLs under /internal are written as https://

Subject: [Zope] Roles, Local Roles, and so on
Message-ID: <20000322213020.A16021@owl.rhein-zeitung.de>

Hi,

I have a question concerning the Role and Local Role system. Well, am I right
with the observation, that Local Roles are only locally assigned global roles?
For example I have an user "oandrich" which is globally just a member of Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to get
really local roles?

Bye, Oliver

emphatically yes- see my message to Erick Mechler re: httpd.conf help.
There are some complications with virtualhosting, because zope only sees
whatever it's listening to, so you have to have a different
<virtualhost> directive for every virtual host as opposed to just
letting zope handle virtualhosting.

phew.

I use a wrapper sql method called UserSettings.

Any calls to data are wrapped in a call to UserSettings eg.

<dtml-in UserSettings>
...
</dtml-in>

UserSettings SQL is : "select * from online where username=<dtml-sqlvar "_.str(AUTHENTICATED_USER)" type=string>"

The online table has columns for data (user name , etc) as text and memos  and permissions (is_super, edit_media...) as logicals
(True/False)

I use the returned information to decide whether an item is displayed or how it is displayed.

No, its a dtml-in for a ZCatalog.
Can I pre-sort the catalog for one MetaData field, and sort the dtml-in
for the other one?

Or are their any easy ways to modify the dtml-in tag to handle multiple sort fields?

Note that the version I posted has several rough edges:

 * It doesn't propagate the CGI environment to the child process.  We
   could fix this on Unixen by doing a fork() and some execve() magic,
   but then we lose the convenience of popen();  CreateProces() on Win32
   requires special handling, too.

 * It doesn't propagate the input stream some CGI's may expect to find.
   "Temp files and fork() and dup(), oh my!"

 * Win32 versions to use the win32.popen(), instead of os.popen().

 * The error handling is ugly.

 * It double-buffers results (which could get ugly if the CGI does
   weird stuff, or returns a really huge result).

In short, its a pretty ugly bandaid, recommended only for easing the CGI
withdrawal jitters. :)  Doing the Right Thing (TM) involves reimplementing a big
chunk of a web server, which is probably why Zope Didn't Go There already. 
mod_rewrite looks pretty sane by comparison.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A09A@express.sematech.org>

I have a dtml-method page that displays a table of values and allows the viewer
to delete on of them (using an sql method on the next page).  All works as
expected, but I noticed an odd thing:  when I used the back button on the
browser the table of values was not updated, but showed the old values.  This is
bad, because people will think their delete did not work.

How do I force a page update?  I checked the IE5 options to make sure it was
checking the date stamp on every visit, so I don't think it's a cache issue,
though I don't know enough about browsing to say it isn't.  Shouldn't forms be
re-submitted on the back button?

I'm sort of confused how this is all handled....

Environemt propagation after a fork wouldn't be too hard, and I was
kindof assuming punting on Win32.

There wouldn't need to be much, just catching errors from the Zope side
code, anything the CGI raises is it's own problem.

I strongly suspect that this is a symptom of a known (to me) incompatibility
between SiteAccess and ZCatalog.  If ZDConfera uses a ZCatalog to track
topics, it will not be able to retrieve them correctly.  I have a patch to
ZCatalog to fix this, but it hasn't been tested by anyone but me.  It just
replaces the resolve_url method of ZCatalog with one that doesn't reenter
ZPublisher.  If you're willing to test it, I'd be happy to send it.

of a document from DTML or an external method? I read through the sources and
maybe I am just to dumb or so to find it, but I can't find any manage_* call,

I have to write a small DTML method, that finds all documents, that are

Message-ID: <B059671903C6D211A0D500C0F0301C792B271D@kubrick.mop.no>

Please send me the patch. The problem does not seem to have anything to
do with URLs, but rather the objects indexed by the topic -- but I could
be wrong here.

Is there a way to modify ZDConfera/ZDiscussions to fix the problem,
without patching ZPublisher? I wouldn't want to break something else in
the process.

I think maybe the issue got clouded by the phrase, "server-side includes".
What you are asking for is not a server-side include:  you want to generate a
tag in Zope, something like:

  <img src="build_graph?units=hours&series_a=hit_count&series_b=load_factor">

This isn't SSI because the browser makes a separate request for the image,
after/while loading the page containing the tag;  SSI is massaged by the server
before the browser ever sees the text.

That said, it *is* feasible to build a parameterized image link, using exactly
this kind of syntax.  There are a couple of contributed products which do
on-the-fly image generation:

  * "gdchart":http://www.zope.org/Members/teyc/ZGDChart 
 
      "draws charts using data from your ZSQLMethod"

  * "TTImage":http://www.zope.org/Members/RainDog/TTImage

      Converts text strings into a GIF/PNG/JPEG images using
      TrueType fonts.

I may have even missed one -- check out the "Zope
Products":http://www.zope.org/Products page.

Without patching ZCatalog, you mean? Hmm.  Possibly.  If ZD* were patched to
use a subclass of ZCatalog which overrode resolve_url, that would work.
Here's the replacement resolve_url for ZCatalog:

    def resolve_url(self, path, REQUEST):
        """
        Attempt to resolve a url into an object in the Zope
        namespace. The url may be absolute (site-relative) or a catalog path
        style url. If no object is found, None is returned.
        No exceptions are raised.
        """
        pparts = filter(None, string.split(path, '/'))
        try:
            obj = getattr(self.aq_parent, pparts.pop(0))
            while pparts:
                obj = obj[pparts.pop(0)]
            return obj
        except:
            return

Yes, most browsers do this.  It's simply a result of their caching.

The only way i know of involves catching hits to the back button involving
JavaScript.  Not pretty, IMHO, nor terribly portable.

Either that, or, as some of our sites have, put up a message saying "DO NOT

Subject: [Zope] How do I get the owner of a document?
Message-ID: <B059671903C6D211A0D500C0F0301C792B2722@kubrick.mop.no>

If the object inherits from CatalogAware, you get a bonus method called
owner(), which you can call like so:

	<p>The owner of this document is <dtml-var owner>.</p>

If not, you can use the get_local_roles() method. You need to iterate it
-- best with an External Method. Like so:

	def GetOwner(self):
	  for Role in self.get_local_roles():
	    if 'Owner' in Role[1]:
	      return Role[0]
	  return 'Zope'

Add this External Method at top-level. Then, thanks to Acquisiton, you
can access the value in any document thus:

	<p>The owner of this document is <dtml-var GetOwner>.</p>

Hope this helps.

Is this application appropriate for Zope?

Yikes, just noticed this one sat in my outbox unqueued :

Going back a month, just have to say thank you Chris.

It does work - I was getting the earlier error messages due
to being a bit ambitious and trying to display all of the 
images.

Just for the record, to get it to work :

1. Create a ZSQL method <ZSQL_SelectPicture> to extract the binary data 
   field ('picture') of one (1) image. That's the important part - one 
   single image.  Don't try to select several records for further logic
   processing.

2. Create a DTML method that returns nothing more than the 
   BLOB data from the ZSQL method, with the correct content type.
   Eg. 
  <dtml-call "RESPONSE.setHeader('content-type', 'image/jpeg')"><dtml-in
ZSQL_SelectPicture><dtml-var picture></dtml-in>

Accessing the DTML method directly will return the image.

This is stunning news.

Still absorbing this, but I think this will have ...interesting... ramifications for Zope in the marketplace.

From the Fact Sheet
"In summary, the ZEO architecture provides the power, flexibility and intelligence needed for the most demanding web applications."

and to think I wasn't going to check my email tonight.

thanks Paul!

Subject: [Zope] Use of Zope for data entry intensive app re-write
References: <38D950FC.F6B7CE47@voyager.net>
Message-ID: <38D96220.DCCD37EE@digicool.com>

I would imagine so... DC has written apps that handle intensive data
entry.. Zope gives you stuff like a security framework, a relational
database interface, a built-in object database, a document templating
language, undo, remote procedure calls from other machines, more.   

But the number of "screens" your application owns isn't really enough
information on which to provide a meaningful judgment.  Does your
application require delegation of authority?  Multiple security levels? 
A management interface?  Personalization?    Would it benefit you to be
able to run the app on multiple platforms without source code change? 
Does XML-RPC buy you anything?  Does FTP access to the ZODB buy you
anything?

Additionally, in the end a decision should generally take in to account
to how comfortable and familiar you are with a product.  If you're new
to Zope, Python, and OO, and you're under the gun to get this project
done and meanwhile you have 7 years of Perl experience, you may want to
seriously consider using Perl.  On the other hand, if you're curious
about Zope, Python, and OO, and you want to get some experience and
you're not tied to anything else in particular, Zope starts to look
really attractive.

Arghh... I should have been more clear, hopefully
someone else already has told you in the meantime,
but if not, the colons should be in the HTML FORM
fields, not inside the target DTML method.

That is, if you have check boxes or multiple select
form-input-elements, you would use something like:

<input type=checkbox name="mychoices:list" value="myvalue1">
...
<select name="mychoices:list" multiple>
<option>
...

Inside DTML, you would just use the name "mychoices" without
the colon. Something like:

  <dtml-in mychoices>
   <dtml-call "qryCAssign(user_id=_['sequence-item'],
                          client_id=client_id)">
  </dtml-in>

If qryCAssign() is a DTML method instead of an
external method, generally you would need to
prepend (_.None, _,... ) to the argument list.
That is, qryCAssign(_.None, _, user_id=.......)

Stable and functional.  It is being tested on several projects.

No.  These are very deep issues, especially the replication part.  If
this is important to you, I suggest using a replicated filesystem to
store the final FileStorage file, like Coda or Intermetzo.

While it would be a great idea for there to be failover and replication,
the issues are complex and without more wide spread use we really don't
want to start engineering a solution (one of the reasons we are open
sourcing it...)

IE will show a cached page, regardless of the settings, when hitting the back button.
If you were to type in the URL, it might actually get the page, but you can never be
too sure with IE.  Its cache is terribly misbehaved.  Try making the page uncacheable
with a Cache-Control: no-cache header.  To verify if this is the problem, hit
ctl-reload in IE (shift-reload in netscape) to force a reload of the page.

This should work (untested):

Some sort of transaction log would be nice. Not only could you track this

on my part.

Paul teased greatly last week with his announcement about a BIG
announcement he was going to make at BALUG. I was going to be out for the
day and not able to keep up with the mail but before I left I checked mail
hoping there would be news as to what it was. Alas no such fortune.

I get back and WOW! This is absolutely tremendous news.
Major, major thanks to all at DC, especially those that pulled the trigger.

I agree that this does set Zope apart from the others. It also set DC apart
from the others in their willingness to do a very good thing.

May DC be greatly blessed and prosper mightily because of the gracious
giving and contributions to the best open source web platform out there.
Once again mucho gracias.

This should be fairly easy to do by creating an external method that calls your
program, then calling the external method using dtml.

Just to nitpick, that isn't true. Zope object ids can contain periods, but it
makes it a pain to refer to those objects in Python expressions. -jfarr

Just for the record, I dont' use FastCGI and have seen Zope
die under the same circumstances; ie. by disconnecting the 
browser mid-download of a (usually long) page. Fortunately, 
that 'client' has been me via the administration screens, 
but it does seem like a rather trivial DoS. 
But it seems that this only happens with certain types of
pages - I'm not sure which.

Unfortunately, I can't remember if this was when we were using 
PCGI or Proxy-Pass, but it was definitely one of the two.

Hearing that others are now experiencing the same gives me
hope: this could explain the crashes that we've been plagued
with for months (though I fear any solution will come too late
to prevent our switch to an alternative platform).
 
chas

ps. Weird thing : the most stable Zope installation I have
    is on NT. It never, ever crashes, despite being the 
    development machine (I wouldn't say that load is causing
    my production server to die b/c it happens under low load
    too).

It seems that a lot of sites (including mine) have problems with Zope's
stability but somehow not many people reported the problems, and I am not
sure whether DC was/is aware of them. Our most useful Zope component right
now is a script that checks our Zope server every 5 minutes and restarts
it if it is down. I have spend many hours debuging but I failed to find
anything sustantial. I am under the impression (but nothing more solid)
that one problem might involve the interaction of the select call and
signal handling or the python wrap around the select call. No proofs
though. Unfortunately like you I failed to convince people in my group to
use Zope for more ambitious projects because of the stability problem.

It may also be due to people using the ZopeMonitor on Unix, which
restarts Zope if it dies.

Even better, it is a part of Zope! :)
From z2.py:
========================================

  -Z path
    Unix only! This option is ignored on windows.
    If this option is specified, a separate managemnt process will
    be created that restarts Zope after a shutdown (or crash).
    The path must point to a pid file that the process will record its
    process id in. The path may be relative, in which case it will be
    relative to the Zope location.
    To prevent use of a separate management process, provide an
    empty string: -Z ''
===========================================

Basically, add the option, along with the requisite options, and there
you go.

the problem is not in your query-code, i guess ..

IIRC, the catalog-aware zclasses are indexed automagically
when created, but not properties you set after creation. So
when you search for track_hasfile='on' , Zcatalog doesn't
have that property indexed:

You'll have to add :
<dtml-call reindex_object> in your Zclass Constructor method
( if you change properties there)

like this :

<dtml-with "Zclass_name.createInObjectManager(REQUEST['id'], REQUEST)">
       <dtml-call "propertysheets.Propertyshhet_name.manage_editProperties(REQUEST)">
       <dtml-call reindex_object>
</dtml-with>

-
Another possibility could be that you haven't added
track_hasfile to your indexes in Zcatalog.
If it is just a on/off-flag (which it looks like from here)
, add it as a field-index..


For better information, check out the excellent Zcatalog /
catalogAware HowTos on zope.org..

try

When you use the double quotation mark, it processes the content between
the double quotes as python code to be executed.  Since there is no
python code called bob, it fails.  Putting single quotes treats the
value as a string.

Hi there,

Thanks all for your help.
I got it working by keeping my old configuration in the ODBC Control

'gsmInfo testowner PASSWORD' as the connect string in Zope.

Cheers,

Message-ID: <38D9EA88.8BB86B9F@nipltd.com>

Hi,

A simple question, but getting a bit irritating...

How can I change the roles assigned to a user without knowing their password?

The form to do this has password fields which come up blank, and you can't submit the form without
filling them in.

I don't want to know what the user's password is anyway, I just want to change the assigned roles...
;-)

HSCH,

Chris

Subject: [Zope] Using a database connection from an external method
Message-ID: <38D9F99C.726D6D4C@funcom.com>

I'm still figuring out how to integrate stuff in and out of Zope, and
thanks to all the people who gave me the friendly advice that I should
stay away from storing blobs in databases (I kind of knew that already,
but guess I was to busy worrying about marshalling things in and out of
Zope).

Anyway, what I am trying to do now is create an external method that
will receive the REQUEST object with some fields AND the uploaded file.
This external method will insert a record into an SQL table and return a
unique ID which I will use for the filename for storing the image in the
local filesystem (I am not worried about LOTS of images in a single
directory - that can be solved by a more intelligent filesystem
[ReiserFS?] or by some clever directory indexing).

Assuming I am able to pull this off, it should be quite easy to pull the
image back in again using the LocalFS product or my own external method.

I guess the external method will be run in the same process and thread
as the Zope process itself, so I would really like to get hold of the
database connection from my database connection instance in Zope. 

From searching the lists, I have learned:

* How to get the ZODB instance using self._p_jar; but this is not what I
need. I need to get the database object for my MySQL database, not ZODB
* How to call ZSQL methods from external methods by simply doing
self.someZSQLmethod

The last method would probably work, but since adding something to my
database table really consists of a database insert, then getting the
unique ID returned and using this for stuffing an image into the local
filesystem, I would prefer to keep this all in the same External method.

So the question then is:

How can I obtain the database connection to the external database (the
"Z MySQL Database Connection" in my case)? And I do not mean the
connection to ZODB.

Thanks,

i have a server running apache, with zope running on a specified port number. when i first created the documents i wanted to run in zope, i created a directory for images and the like in the zodb. after studying the structure of my site, i've decided i'd rather have the images directory in the server's folder system as opposed to the zodb. moving the images and such is no problem, however, the linkage from the documents to the images is going to be a big one. is there a way to set up something like a symbolic link from the images directory in the zodb to the images directory in the server folder system so i don't have to go in and manually modify the path for each image?

You can specify ":list" in your checkbox code to typecast the input.

Here is a quick test. The list should display OK when one checkbox is checked.

<FORM method="post">
<INPUT type="checkbox" name="myList:list" value="First">First<BR>
<INPUT type="checkbox" name="myList:list" value="Second">Second<BR>

<dtml-if btOK>
  <dtml-if myList>
   <SELECT name="myList">
    <dtml-in myList>
     <OPTION><dtml-var sequence-item></OPTION>
    </dtml-in>
   </SELECT>
  </dtml-if>
</dtml-if>

<INPUT type="submit" name="btOK" value="OK">
</FORM>

This creates a user from python - nice, but doesn't solve my problem. I want
to be able to assign a property sheet of some sort to each user I create, so
I can store his/her local preferences on my site.

Does anybody have a clue on how to accomplish this?

Thanks for the suggestion, though.

Message-ID: <38DA05CD.7F089CCC@nipltd.com>

Hi,

I was thinking about putting my 'Changing Roles' problem into the collector as either a bug or a
feature request so I went and had a look.

It's REALLY hard to try and find out whether anyone else has done this before.
Not only is there not any real categorization of bugs/featrues within Zope (everything seems to be
'General') but neither the search or advanced search is documented.

Most irritating though was that it doesn't look like you can read problems unless they're been
solved, so although there were a couple of bug titles which looked like they could be what I was
talking about, they were all ***This item is under review*** so I couldn't check.

By all means flame me if I'm being stupid, but otherwise coudl someone help me out?

cheers,

Chris

Actually dots are allowed in object names. You can create a picture called 
"myPic.jpg" and insert it with <dtml-var myPic.jpg>.

However because of their special meaning in Python they make it more 
difficult to access objects in Python expressions from DTML.

Example, to access the picture title, you'd need to use :

<dtml-var "_['myPic.jpg'].title">

or (simpler but longer)

<dtml-with myPic.jpg>
    <dtml-var title>
</dtml-with>

Subject: [Zope] Roles, Local Roles, and so on


Hi,

I have a question concerning the Role and Local Role system. Well, am I
right
with the observation, that Local Roles are only locally assigned global
roles?
For example I have an user "oandrich" which is globally just a member of
Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available
below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders
of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online
admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is
no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to
get
really local roles?

Bye, Oliver


[RH]Oliver,

the current role system lets you assign roles from a certain object (you can
add them under the security tab).

You could also devise a method or a product that (manually) registers the
roles a user is entitled to (or already has, depending on the situation),
but that could get you turning in circles easily.

Rik

Would it work for you to create a folder for each user with id same as the
username?
You get a propertysheet with the folder for free. You could also make good use
of acquisition to display pages based on preferences.

The easiest option is simply to wait a bit til the PTK version is working. 
Or even help out yourself with this part of the code.  Otherwise, you can,
for example, create an SQL table (in gadfly) with the username as an unique
index and properties as other columns.

Okay, I've put this into the collector now (hence my complaints about the collector ;-)

I've got a proposal:

How about leaving the form as is, but if the password fields are blank, then don't change the user's
password?

I might have a look at coding this later today.

If I do, how do I get it into the CVS or back to DC in some other way that it'll make it into the
next Zope point release?

cheers,

Chris

I am not in a position to go into a testing program in mid-april,
however I think there are probably many of us who wouldn't or don't
currently qualify who would simply like observer status on a mailing
list or something. That way we can at least begin the learning process.
It also puts more eyes on the problem.

Your question addresses a fundamental lack in Zope.  Zope was developed
internally in a closed source fasion for years to address the needs of
paying customers.  These customers typically did not design applications
themselves, we did all of that.  Therefore, much of Zope's API is fairly
oriented toward specific directions and there are big gaping holes.

Don't let that discourage, you, there are big gaping holes in all
software.  We are working on a project right now to come up with a solid
undertanding of interfaces in Zope.  While this may seem like a simple
task, it is not, but we are working on it and we are making progress. 
Here, you have come upon a hole, there is a method that lets you do a
number of things in one call but there are no decomposed methods that
let you do finer grained tasks.  This kind of situation is common, not
just in Zope, but in lots of software where extensability is very
important.

Unfortunatly, this is a gnarly problem.  For example, if we decompose
manage_users() into a number of smaller methods, it would make sense for
us to re-implement manage_users() to use those methods.  But this
involves not only writing a bunch of new methods but also taking solid
proven code and discarding it for new code, based on even _newer_ code. 
This problem becomes almost nauseatingly dificult when you consider that
we could turn this process to all objects in Zope, Folders,
ObjectManagers, ZCatalogs... And while it may seem clear there should be
so and so methods to decompose to, we need to make sure we think hard
about issues like, should they be callable via XML-RPC?  Will this new
method reveal a security exploit?  etc...

I don't want to take the wind out of your sails, perhaps you could
suggest some improvments, all the code is there.  For now we are taking
small steps, document what is there, propose a framework for sensible
extension, and then fill in some of the gaps, and tear down some of the
cruft.  I will make a note of your question for when we get to security.

I totally agree, don't worry... no wind taken out of any sails ;-)

After all, Zope is free and there are plenty of (very) expensive alternatives that will have just
the same sort of problems.

Hope I can help at some stage :-)

Aye carumba, I haven't even been following this thread, not the most
useful subject line!

Ok, it looks like there are two issues:

1) some sort of FCGI issue which I do not have the capacity to reproduce

2) the same stability issue I am currently looking into.

The problem with 2) is that no one can reproduce it reliably (this may
not be true after I look at something someone sent me today, I'll keep
everyone updated) including myself.  I have pounded a half dozen
sandboxes with ab for hours and gotten nowhere.  No crashes.  Not a
single burp.

I'm, of course still looking into this, but I need more data from the
folks out there.

First of all, if you suspect that your Zope is dying and restarting
alot, run it in debug mode like this (unix only, sorry):

bash$ strace -f -e trace=none -signal=all python z2.py -D

See 'man strace' for the gory details.

obviously tune the parameters to z2.py to suite your needs.

What we are looking for here are SIGSEGV.  You'll probably see a lot of
SIGUSR1s, these are normal.

If you can get a SIGSEGV to happen reliably, _please_ let me know.

You'll have to roll your own form, and have it call manage_users on the user
object with the variable 'remote_user_mode__=1'.  For example::

 
<URL:http://server:8080/acl_users/manage_users?name=fred&submit=Edit&remote_user_mode__=1>

suppreses the password display (but it is still there in hidden input field!)

You aren't being stupid at all.  Here is the low-down on the Collector:

 * New items in the collector are immediately marked "under review" 

 * "Under review" issues can't be viewed until they get marked "in work"
   or some such, allowing submission of security-sensitive bugs without
   publicizing them to "black hats."

 * Most issues sit in the "under review" state far longer than the minimum
   time to triage out the security bugs; this is a lamentable corrollary to
   DC's short-handedness.

Fixing this problem would require adding to the Collector a new state,
"submitted", which then becomes the "show no details to black hats" state, and
sending off nightly emails of "submitted" bugs to the sucker^H^H^H^H^Hteam
member responsible for the Collector.  Moving the bug to "under review" should
then make it visible to outsiders in all its glory.

Hello everybody!

Please join me in welcoming Matt Burleigh to the Digital Creations
team!!

Matt joins us as our first (and sorely needed!) system administrator.

From Matt's man page:
"""
I call beautiful and historic Fredericksburg, Virginia my /home.
Fishing, hunting, and reading civil war history are my hobbies.  Don't
tell anyone but I've taken many tech support calls from a boat and even
lost a cell phone in the lake once.

In 1983 I got a 1200 baud modem for my 64k IBM PC and it was down hill
from there. Sometimes I feel like I spent all of my life in front of a
computer. I started the first BBS in the Fredericksburg area and a quite
successful one. Eventually becoming Central Virginia mail hub for
FidoNET and sucking Usenet newsgroup feeds off of a satellite dish then
divvying it up for the local area SysOps. Those Usenet feeds were from
this thing called the Internet, which took me by suprise in 1994. At the
time I was running a small computer sales and service shop in the area.

Once I realized that BBS's and RIP Script (a graphical language for
BBS's that was going revolutionize the online world, ha!) wasn't going
to make it, we switched our dial-up modems to direct connections to
ISPs.

In 1996 a friend of mine introduced me to Slackware Linux. This crude
operating system really intrigued me and I found it to be an exciting
new challenge. A couple months later I began selling used machines with
IP masquerading and firewall setups. Soon after that, I convinced a
customer of mine to switch from the ever failing Windows NT v3.51 to
Linux. The system ran for over 6 months with not one problem or required
reboot. I was hooked and swore never to install Windows NT again.

You could try:
<dtml-call "RESPONSE.expireCookie('main_counter'">

which might work.

Hello all:

Not sure if this has been asked before, probably yes, but haven't been

Does any of you has been able to print from a Zope application to a
printer attached to the same machine where Zope is running, in my case
it's a Red Hat Linux 6.1 box.

I need to print from Zope with a specific printing format (like
invoices, receipts, etc).  This will be done on always the same Intranet
and printing will be controlled from the Linux spooling system.

If you can copy your comments to me by email besides the mail list, it'd
be great.

,Any help is appreciated, thanks in advance.

I am not usre what you need to do. The cookie name is SassionUID. If you
need to delete something from the FSSession data use FSSession.delete
like:

<dtml-call "FSSession.delete('main_counter')">

you can expire the cookie by ... reading Chris followup email (just

Message-ID: <Pine.LNX.3.96.1000323155356.11696K-100000@marvin.nipltd.com>

My saga with the standard_error_message continues ;-)

I'm trapping 404 errors for missing pages, checking the intended URL
against a list of URLs which have moved to new locations and returning a
link to the new location as part of the error page.

What would be useful would be to automatically redirect to a new URL if
it occurs, but this is proving a problem. I've been using
RESPONSE.redirect() as this has proved useful on other pages, but on
standard_error_message this doesn't appear to have any effect - even when
the entire contents of the error page is stripped out and replaced by just
the call to redirect().

Is it possible for standard_error_message to handle redirects (in which
case, what else do I need to do?) or is there another way to go about
this?


Thanks in advance.

John

Subject: [Zope] records form variable type
Message-ID: <wksnxh8xai.fsf@email.aston.ac.uk>

I have been using the records form variable type, but believe there
may be a problem with it. With most browsers all appears OK, however some
browsers (e.g. Mozilla) may return form elements out of order. What
this means is that when trying to use the records type their is no
guarantee that the different elements of a single record will be sent
consecutively and therefore the records objects will not be correctly
constructed by Zope.

I would like to know if this is the fault of browser or if this is an
issue which excludes the general use of the records type. If the
latter what alternatives would be recommended - I would prefer not to
have to create unique form element names as it would add a fair amount
of complication. 


What guarantees can be safely assumed about data arriving from a form
- for example if you try using the list type is the order in which the
components of the list guaranteed to be the same as the order in which
the respective form elements occur in the document?

i'm getting some funny behavior using a (separate from Zope's)
ZODB from External Methods.  after much thrashing, i've got my
application working.  however, every so often, when i click 
on a submit button that invokes an External Method, i get:

   Could not lock the database file. There must be another process
   that has opened the file. 

the odd thing is that if i click the browser "back" button, then
hit my button again, it works.  occasionally i need do this
back/resubmit thing more than once, but usually once suffices.

smells like a race condition to me.
has anyone else seen this, or have an idea how i can avoid it?

http://www.reportlab.com/ may be what you need.  It's in Python, so it
should be easy to hook up to Zope, and it outputs PDF which can then be sent
to lpr for printing.  Since RH uses Ghostscript as a print driver the
generated docs should print fine.

I would favor making it like the HowTo list; where you can organize by
title, date, author, and reverse them. The code should be a basic
copy-paste with slight modifications operation.

Just wondering if anyone has thought about personalization
services based on Zope ? 

The most obvious/traditional approach seems to be :
1. Acquire user information (via forms/surveys/transaction-histories etc)
   and store in RDB. 
2. When the user comes to the site (and either logs in or is identified 
   by IP or cookie), query the RDB for customized content or appropriate
   products. 

OK, no magic there. But it's not very scalable in terms of :
a) Load. We can keep shoving Zope servers on the front end
   but the RDB is going to get hammered if this has to occur
   for each and every request. 
b) Development. A more object-oriented approach would be nicer.
   eg. Personalities with behaviours and properties. 
   Could a pool of persistent personalities be left floating 
   around ? (No, this is not an early April's fool) 

A while back (1997) I saw Broadvision and didn't really appreciate
what they were doing. It seems that they've really improved a lot
since then but I can't get my hands on their software (not for free
anyway). So, I'm wondering if anybody has experience with it and 
can enlighten a heathen on key features we might wish to, er, 
'appropriate' in Zope systems ?  Or is it, like Vignette and Netscape
ECXpert, nothing special and you're basically paying for the 'knowhow' ? 

Thank you,

Message-ID: <002b01bf94e6$968a7af0$f2381bd8@LIPS>

hello:

i'm using Zope 2.1.6 and LocalFS 0.1.7.  when i try to view an image via a
LocalFS object i get an exception in OFS.Image.py at line 187:

last_mod =int(self._p_mtime)

the error occurs the *first* time i try to access a specific image with a
recently launched browser.  accessing other images or subsequent hits to the
troublesome image in the same browser do not cause the problem.  subsequent
hits in the same launch of zope from a fresh browser on another machine
causes the exception.

having modified Image.py to catch the exception and dump some information i
see that self._p_mtime is None.  i've looked around but cannot determine
where _p_mtime is defined or how it is supposed to be set.

i see this method in Image was re-written after Zope 2.1.4.

similarly, accessing a .wav file via LocalFS causes the following message:

2000-03-23T16:27:13 ERROR(200) ZServer uncaptured python exception, closing

the wav file is delivered to the browser correctly.

as a quick fix to the Image problem, i catch the exception, set last_mod =
0, and continue.  this does not seem to have any ill effects.

There was a CVS Checkin today for this problem.  You might want to check

Subject: [Zope] ZWiki comments
Message-ID: <38DA502B.B20E8928@texoma.net>

For a previous message I posted to the list I was prompted to place a
comment in the associated ZWiki.

I went to the ZWiki to comment and played with the "Sandbox" before
posting to learn a few things. From the things I learned here are a
couple of comments I wanted to throw out. I know some of these run
counter to the thoughts of the Wiki community but they are concerns
nevertheless.

The nature of Wiki is very unsecured. This is for better or worse. I
know the ZWiki on the Zope site does require logging in before editing
which helps but does not eliminate the potential of malicious or
accidental editing.

Anyone logged in can do any kind of editing they wish on a page. They
can erase all text. They can insert, delete or otherwise modify comments
or content made by other people. These things can be positive or
negative depending on the goal or intent of the page.

I think editing a page is more applicable to stable open content than it
is to a forum oriented page.

Examples.

If Zope's documentation was managed by ZWiki in a secure manner then a
community member could make corrections of typo's or legacy information
like references to Principia, etc. The submit button could either be a
"Submit for review" or if really trusted "Change". I know this
duplicates somewhat what CVS does. Once again depends on goals.

If the page is forum oriented, i.e.: an on going conversation like a
bulletin board and such then it is more appropriate to "Add comment"
than to "Change page". This would present the user with a cleaner
interface and a clearer idea of what they are doing. They would not be
presented with the entire contents of a page so they could merely append
a comment on the end.


If the ZWiki on the Zope site starts getting busy we run into other
problems. The problems especially affect a forum oriented type page.
Just to learn I opened up the "Sandbox" in a new page, I then open the
"Sandbox" again in a new page. I edited the first and submitted and then
edited the second and submitted. The first was successful. The second
fortunately got an error message. I say fortunately because it did not
overwrite the previous submission.

In a busy forum or BBoard multiple people getting errors would be a bad
thing. If in a forum oriented page an "Add comment" button was available
then the conflicts and errors would be avoided. This would also enable
ZODB's transaction mechanism better with each comment being an object
associated with the page.

This would also be more secure in that people would adding their value
and not altering other peoples.

On Philip Greenspun's site  http://www.photo.net  the BBoard's are
somewhat integrated with email. You can subscribe to a bboard and
receive email for the added comments. This is a nice feature. Their
implementation is quite inelegant and could be improved. Zope/ZWiki
could shine here. This allows user to choose how they want to view the
messages, either through the web or via email.

Just a few thoughts to throw out to the community.

Actuatly, there may be one other quicker method to do this.  You can somehow
(i haven't tried this) compile php into a stand alown executable.  Then you
could then have an external method do a shell call running the php script.
Another interesting thing you could do would be to make a zope product that
stored php3 code, and then called out to php to parse it.  This might not be
a bad way to allow clients to have their own maintainable php3 scripts up
on the web without giving them ftp or shell access.  hmm..

I was thinking of a general simple caching product for Zope, to use in
conjuction with FSSession for high load sites. A simple implementation is
to use an in memory python dictionary to hold marshalled or cPickled data.
Since the access times are fast we could use the asyncore classes that
come with python to achieve really high rates. The cache contents can be
served from a socket or a named pipe. A more difficult but more efficient
way is to use shared memory for IPC. As I don't expect two clients to
connect simultaneously with the same user id, write conflicts will be few
(I suppose writes will be few too).

In our environment I have found FSSession to be very fast, probably
because the OS caches files. If someone complains about FSSession's speed
I will code the caching product.

Would there be any potential for allowing people who are doing

I am very interested in learning the ZEO architecture and capabilities

On Zope, I created a new ZClass, EBook which is Subclassing, CatalogAware,

I created an instance of EBook which id is 'aid' in a Folder called 'new_test'.
It works fine in Zope except I cannot use my writeData method of my EBook
class because of the following error: 

Error Type: IOError
Error Value: [Errno 13] Permission denied: '/home/oscar/data/test_out.jpg'

I work with Linux and all users have the right to write in /home/oscar/data'.
I even tried to run the method from the interpreter, just changin
f.write(self.data) to f.write('arbitrary string') and it works fine.

**Can you tell me where am I wrong?**

I also tried to use the debugger to understand where I am wrong.

Or even better, a generalized version - so you could serve perl and php and
python cgi  scripts transparently from zope.  That's be pretty cool actually
- migrating our old sites from php to Zope would be trivial.  

Of course, it'd be much slower than having PHP3 compiled in to Apache.

Subject: [Zope] ZEO app architecture options
Message-ID: <38DA5AD1.EE6A264B@texoma.net>

Hello,

In light of ZEO becoming open source, I'm still extremely excited, I
want to revisit some questions I threw out in a previous thread about
Zope's scalability.

Can I architect a website like this using different Zope Storage Servers
for the various directories or 'would be' tables in an RDBMS? Yes, I
understand the impact of the OS filesystem concerning ZODB size.

Say for example I have a large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5+gb directory which is reasonably
stable updated monthly.
ZAuto/manufacturers isn't as large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.


Also, when comments are made about Zope's ZODB or ZSS not being
appropriate for heavy write apps, does this refer to apps doing
"updates" on objects or doing "inserts" or both using SQL terminology?

Would structuring an app like above help in write situations?

I am trying to determine the desirability or necessity of an RDBMS for
my idea. I like keeping it in Zope if reasonable and ZEO can definitely
help. If need be I'll go to an RDBMS for certain data.

Thanks for any help or clues.

As much as I appreciate the desire to get at ZEO early, we have to
balance that with our limited resources internally.  We're taking a
conservative approach to getting it out the door, rather than just
dumping code and telling people they're on their own.

Hopefully everyone can appreciate this.  Unfortunately we're taking a
lot of flak, for instance, for not releasing Tracker.  I wish we had
unlimited resources, but that's just not the case.  As everyone in the
Zope community will probably agree, we need to do a better job and not a
bigger job.

This isn't necessarily true.  Zope caches objects, and the scenario you
describe is well suited to the caching strategy.  (That is, a user is
probably going to come back again within a minute of their previous
request.)

Compare this to an RDBMS strategy where state is always being retrieved
on each request.

The PTK membership model allows arbitrary extension of methods and
attributes.

Sorry, I forgot that I hadn't uploaded the text of the FAQ.  My network
connection was horrible yesterday (I'm in a hotel in the Bay Area right

You'll need to write some software in Python that will interface with
Zope for printing to your local Linux printer. In general, this isn't
something one would normally go about doing.

Is there anyway of debugging the interaction between Zope and Apache rewrite?

Why not use something like SWIG (I don't know much about it, just a general
idea on what it does), to link the interpreter to python, and then make a
Zope extension like <dtml-perl xxx> to call it? Then you could probably get
the perl/PHP scripts into the ZODB, and therefore get cached, making it even
faster..

i think you need to set permissions to execute cgis within that
section, ie. put

Options ExecCGI

into your <VirtualHost></VirtualHost> section

Subject: [Zope] Troubles with SQL queries
Message-ID: <Pine.LNX.4.10.10003231313390.10023-100000@odeon.net>

Heya folks,

I've got an SQL query that looks like the following:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.date, gigs.start_time

This works fine.  The '/'s indicate that a single line continues, in the
ZSQL method the 'and gigs.date >= etc." part is on one line.

I'd link to be able to change the values the query is ordered by based on
the link used to access it.  Something like the following:

http://foo.bar.com/Zope/query?first=date&second=start_time

Towards that end I made the above look like:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.<dtml-sqlvar first type=string>, /
    gigs.<dtml-sqlvar second type=string>

When I test the ZSQL method it shows the SQL used as:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "2000/03/23"
  order by gigs.'date', gigs.'start_time'

Note the 'date' and 'start_time'...  Because of the 's the query does not
work.  

Is there a way to not have the <dtml-sqlvar> tag return the 's to MySQL,
or is there another way I should be trying to do this?

Thanks for the help,

Jeff Robertson

From: garry@sage.att.com (Garry Hodgson)
Date: Thu, 23 Mar 2000 15:38:01 -0500
Subject: [Zope] How do I pass parms past a redirect?
Message-ID: <38DA80A9.411DFC15@sage.att.com>

i'm building an app that requires me to connect to another
server in the company to do employee authentication.
one connects to that site, passing a return URL.
it verifies the employee, sets a cookie, and redirects
to the URL you gave it.

so, in a document i want to protect, say, ChangePerson.dtml,
i've got something like:

<dtml-if "REQUEST.cookies.has_key( 'attESSec' )">

	...regular actions for the page...

	<dtml-call "RESPONSE.expireCookie( 'attESSec' )">
<dtml-else>
	Missing attESSec cookie!
	<dtml-call "RESPONSE.redirect(
'http://othersite/cgi-bin/authenticate?retURL=http://mysite:8080/ChangePerson&sysName=foo'
)">
</dtml-if>

note that the URL i redirect to expects two parameters,
retURL says where to return, and
sysName is an application name given when
i registered to use their services.

so far, so good.  the problem is, my document expects to be
called with some parameters passed, like:

	<a href=ChangePerson?hrid=1234567&name=garry>Change</a>

now, i can't encode these parameters in the retURL
i pass the other site, as i get a "malformed syntax" error.

so, my question is, how do i make this information available
to my script on the return?  do i set a variable in the container?
set a cookie?  or is there some better way?

to broaden a bit, how does one pass information around in general?
so far, i see several methods, for calling:

External Method: piece of cake.  real live arglists, like god intended.
DMTL Doc from form: form variables, mixing hidden vars in for other
stuff.
HTML links: cgi-style syntax, leads to ugly URLs.

is this the right way to do things, or am i missing something?

Subject: [Zope] xmlrpc authentication woes
Message-ID: <38DA8147.3E2F3325@boi.hp.com>

First, let me say I have patched my xmlrpclib.py to support
authentication; that isn't the problem.

Overview:
I have a folder, 'Administration', which requires manager login to
access. In this folder is a subfolder called 'MachineTracker'. In this
folder is a collection of ZSQl Methods, DTML Methods, and DTML
Documents. What I want to do is to connect to the server via XML-RPC,
and make use of the ZSQL Method for inserting data into the database.

Problem:
When attempting this from python in XML-RPC, I get a 401 Unauthorized
error. I can access the folder, and other methods, such as index_html()
and objectIds() with no authentication issues. 

Any ideas?

(please cc me here, this isn't my subscribed address)
TIA, Bill

 You can use one of the Session products (SQLSession or FSSession) to
store arbitrary per session info (even Zope objects) on the server. It is
probably the cleanest solution.

Use the handy dandy Python range operator (generates a list of ascending
integers of a specified length):

<dtml-in "_.range(noOfTimes)">
  <input type="text" name="...

A simple question, how can I determine the Owner
of a ZClass instance (or any Zope object for that matter)?

My users create instances of a Seminar ZClass.  I did not
create a SubmittedBy property (which I would fill from
AUTHENTICATED_USER.getUserName()) thinking that I could
easily extract this from the Owner role.  I just can't
see how to do it.

I have run into this problem before.  Floating about on the ZOPE site is a
patch for the MIMETools, which addes a few *_expr attributes, so you can replace

name="_['file.filename']"

with:

name_expr="_['file.filename]"

I have just written my own tag product (may or may not be allowed to release..
we'll see :)  I understand now why this is so.  It seems that, so far as the
product is concerned, there is no real way to tell the difference between a
string and an expression.

If I am mistaken, I would dearly LOVE someone to point me in the right
direction.  I currently distinguish vars and strings by if they have 's around
them, and expressions are attrib_expr.

But I digress.... the patch is your friend.. It is on the ZOPE site (sorry I
can't be more specific, but a quick search will find it.)  I have used it
myself, and know it works.

Message-ID: <000f01bf9521$065bc480$2aac8ec6@hikari.anu.edu.au>

I have a container ZClass Person.  Person has a (string) property
CurrentPosition which gives the id of a ZClass instance contained
in Person.  Example:

   DarranEdmundson (Person)
       bsc_degree (Degree)
       phd_degree (Degree)
       fellow     (Academic)
       fujitsu    (employment)
       vizlab     (employment)

where DarranEdmundson.CurrentPosition = "vizlab"


I am having problems accessing the CurrentPosition object
in a pythonMethod.

list = []
for person in self.objectValues('Person'):
     position = _.getitem(person.CurrentPosition)
     list.append(person.LastName, position.anyProperty))


I can do it in DTML via

<dtml-in "objectValues('Person')">
<dtml-with "_.getitem(CurrentPosition)">
   <dtml-var LastName> <dtml-var anyProperty>
</dtml-with>
</dtml-in>

I think the question really comes down to: how does one
achieve <dtml-with name> in a pythonMethod?

Subject: [Zope] how to get the fields returned SQL method
Message-ID: <86ln39meyg.fsf@marcelle.revolink.com>

Hello,

I'm trying to get a list of fields returned by a dynamic SQL query.
I've found a howto telling me to write something like :
	<dtml-in SQL.names>
	<dtml-var sequence-item>
	</dtml-in>
But it doesn't work : I get the error "Attribute Error : names".
I've tried with .items, .keys and .fields too.

I'd like to do the same for an LDAP query.


Any idea ? I think it's very useful and that an easy way exists but I
can't find it.


Thanks,

EB.

OK, so I read the Advanced Catalog Search HowTo, and I am left with
a couple of questions.  I'm concerned here with "or"ing the searches
on two fields.  The first question is, once I do the OR is the
result (which may be close to a thousand records) cached?  Otherwise
I don't think this is going to work.  Even if it is cached, I'm
thinking it may not work.  Is there any way to do an OR without
loading both result sets into memory?

The other question is, when I do the OR, how do I reduce the
composed list to just unique records?  The HowTo seems to just
do a sequence join, which would leave me with duplicated records
for those items that matched on both search columns.

Well, since the SQL will return a list, firsly you would have to index it...
also, .keys et al are Python stuff, so...(untested)

<dtml-in "SQL[0].keys()">

might be more what you're looking for.  Or...

<dtml-in SQL>
  <dtml-in "keys()">
    <dtml-var sequence-item>
  </dtml-in>
</dtml-in>


should iterate through the keys of each line of the returned table.

ZEO is transparent to the application, it is a _singular storage_
meaning that all the issues of multiple databases still apply, re, they
are not yet supported.

What this needs is the ZDBF (Zope DataBase Framework).  This is a layer
that sits above ZODB.  Currently, ZODB takes care of all these issues
(or punts on them) when really a higher level abstraction should handle
multiple database issues (including any future extensions to the
Relational/Object model).  Obviously, this is a big task.  See paul's
email about resources. ;)

First, keep in mind that to a certain degree, all databases are
sensitive to the high-write issue.  ZODB is more sensitive because it's
conflict resolution is optimisitic.  FileStorage is also sensitive
because of the  inherent behavior of filesystems, and ZEO is sensitive
because for every object written, an invalidation message must be sent
to all other ZEOs so that they are given the chance to invalidate the
object in their cache.  This also increases chances of collisions
because the Time To Write a record is extended for varous reasons
(network delay, invalidation delay, etc...).
 
> Would structuring an app like above help in write situations?

Not without ZDBF.  Multiple database support would allow you to use
different, less write sensitive storages like a RelationalStorage or a
BerkeleyStorage.

Do some benchmarks, ZODB is very fast if you are a little more clever
about how you change your objects.  If you need more write intensiveness
go relational.

One doesn't.  Instead one uses local variables, as you did with 'person'.
Your solution is almost complete, actually, and should work if you replace
'_.getitem(person.CurrentPosition)' with one of the following (I'm not sure
which, you'll need to experiment):

person[person.CurrentPosition]
getattr(person, person.CurrentPosition)
person.aq_acquire(person.CurrentPostion)

Sorry I can't be more specific.  In general, though, any place you would use
dtml-with in DTML, you set up a local variable in PythonMethods.

Cheers,

Evan @ 4-am & digicool

Message-ID: <200003240350.AA11082@rsphy9.anu.edu.au>

I recently took the site I have been developing online
and have been beta testing with several users.  I
have a problem which is preventing a user from
viewing his home page; any attempt I make to isolate
the problem hangs Zope, stops anyone accessing
my site, and requires a forced unix kill.

The user's page is:
   http://rsphysse.anu.edu.au/optics/people/jdl124

Users are implemented as a Person ZClass.  One
of their contained objects is a PublicationFolder
ZClass, itself a container class for Journal ZClass
instances.  So above:

optics (folder)
   people (folder)
      jdl124 (Person)
         publications (PublicationFolder)
             article1 (Journal)
             article2 (Journal)
                .
                .
             article69 (Journal)


jdl124's home page is dying when it tries to iterate
over the results from a search of the ZCatalog publicationCatalog.

The problem isn't in the publicationCatalog however, the following DTML snippet locks up my Zope completely:

<dtml-with jdl124>
<dtml-with publications>
<dtml-in "objectValues()">
    <dtml-var id><br>
</dtml-in>
</dtml-with>
</dtml-with>

I can deal with this during solo testing but my users' budding confidence in the system I have created
has been mildly rocked by this situation.  Needless to say, jdl124 is none too impressed.  Any help
you can offer is most appreciated.

Cheers,
Darran.

This is a bit odd.  I have some image objects that display fine in
IE 4, but in Netscape 4 I get a Zope error

Invalid Date-Time String
Tuesday, 29-Feb-00 17:53:59

The traceback ends with DateTime.py, line 848, in _parse.

Is this a Y2K-leap error, or is something else going on here?  I've
checked two of these images and in both cases the date it is
complaining about is on the 29th.

And why only Netscape 4 and not IE?

I think you want this, which (it claims) generates PDF documents within
zope.

http://yyy.zope.org/Members/gaaros/ZpdfDocument

Then you just print it however your clients are already printing.

--------------11C1869DF092DB44C388B170
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

Assuming you are just going to be using linux this shouldn't be _too_ hard.

You probably would want to firstly use the http client module in python
(not sure exactly what it is sorry). Which could download a html page which
is generated by Zope.

The with the html page you can make a system call to "html2ps temphtmlfile temppsfile;  lpr temppsfile -Pprinter". Python has the ability to simply call 
external program (i think it is os.system( ) ). Of course you could find/write
your own html->ps and printing code but when you already have html2ps and lpr
I wouldn't really bother.

Now if you wrap all that up into an external method which is called when the 
print button is pressed it should be quite acceptable.

Is this the type of thing you want or am I off in another planet?

Why not generate a PDF file on the local file system and then print it

I think a translator should implemented using a flag in dtml-var:

syntax: <dtml-var VARIABLE translate> and <dtml-var VARIABLE 
translate="de"> for example.
Short form: &dtml.translate-VARIABLE;

By default it chooses the root folder's (or even Zope's?) language setting, 
but the programmer can also choose the language. This syntax is very 
similar to the "missing" flag. This way you do not a separate phrasebook 
and word translator. All that is in the background....

Then there is a generic translate product which handles all the translation 
stuff and administrates the languages. One can easily drop languages into 
the product, by installing simply the dictionary for this language into 
some standard location and specifying some admin info.
I think that would be the cleanest way to implement ZIP.

What do you guys think? Comments?

Stephan

I tried sticking <dtml-var get_local_roles> in a dtml document and got a blank list back even though
I know I've got some local roles.

Also, where did you find out about this? I haven't found it documented anywhere...

<dtml-var "AUTHENTICATED_USER.getRoles()"> is also not too useful since it only returns roles where
the user object is defined, ie no local roles...

What am I doing wrong?

References: <86ln39meyg.fsf@marcelle.revolink.com>

Okay, a lot depends on what your query is returning.

If 'names' is not the name of a column, then ignore the rest of this message ;-)

If it is, then try the following:
<dtml-in SQL>
 <dtml-var names><BR>
</dtml-in>

- If 'SQL' returns a single row and 'names' is a single-valued column, then it should display the
value of names.
- If 'SQL' returns multiple rows and 'names' is a single-valued column, then it should display the
value of names for each row returned on a seperate line.
- If names is a multi-valued column then you should get something like
  [...,...,...]
  for each row returned.

cheers,

Chris 


If names is a single-valued column then the following should work

I experienced this as well also on Netscape (but I didn't try with IE)

Did you create the images on Feb 29th? I think I did and made the problem go away by re-uploading
the images.

This is a bit of a worry though, anyone got any ideas what's going on?

Hi Chris

I wrote Amos for exactly the same thing and here is his answer:

...
This is a Zope error. I was working with a development version of Zope
which didn't have the error. The error is fixed in CVS and should ship
in the next release of Zope. To fix the error add this line near the top
of your lib/python/Products/ZCatalog/ZCatalog.py file.

from DocumentTemplate.DT_Util import Eval, expr_globals

This should work if 'id' is what appears in the management view, etc...
What do you mean by string value?

Hmm, are you sure you're not trying to include python methods rather than DTML documents or DTML
methods?

Try:
<dtml-var "id()"> if there's not another reason why this isn't working...

| HOW do I get the real document contents???

Provided that ID contains a string representation of the id of the
document you want, this should do it:

<dtml-var "_[id]">

I hope I understood what you wanted to do, this may very well be
solving the wrong problem.

Hmm. That's not what happens for me. I get something like:

[('admin', ['Owner'])]

How do you know you've got some local roles? Also, is this a DTML document or
DTML method, because methods seem to acquire the roles from their container.

> Also, where did you find out about this? I haven't found it documented

It's all in AccessControl/Role.py.

IMO the documentation is just a good place to figure out where to start reading
the code. ;)

Is there any simple way to do this kind of things in

I downloaded Zope-2.1.6-linux2-x86.tgz. I unpacked it in /usr/local/bin,
then ./install, then ./start. Please see below and advise.

I tried logging in several times. I even used python zpasswd.py access and

Subject: [Zope] error with ptk
Message-ID: <028801bf9584$2e178be0$722624d5@amazigh1>

I began to download and to install PTK's last version recently. I installed
the product by following procedure described in the file " Read Me ", and I
so obtained three new elements in the section products. But when I try to
create a new element "Portal", Zope sends back me an error. I search so the
details of the installed products and I notice that in the part " DemoPortal
" certain elements are broken:

It is a question of:
 . " DemoPortal / Portal "
 . " DemoPortal / PortalWizard "
 . " DemoPortal / Wizard "

In fact they are all the DemoPortal's ZClass which are lacking. Can it
involve a conflict with another product? Is it necessary to settle PTK on
Zope's clean version?

I work with:
Zope version: Zope 2.1.2 (binary release, python 1.5.2 , win32-x86) on Win
NT4 / sp4, as well as with Zope 2.1.4 on Linux Mandrake 7.0. (on whom I did
not test PTK because it is my working environment, and I do not wish to
pollute it).

Thank you for advices. I intervene only rarely. What is well , it is that
major subjects and basic questions were approached in depth, repeatedly,
what allows to avoid resting the same questions. By getting back this
information, the people of the ZDP make a formidable job. That has the taste
of object oriented thinking...

Your best bet is http://zdp.zope.org

PS: In reality, the best way to learn Zope (IMHO) is to start with the guides
and then read the mailing list religiously.

The guides are at:

good luck, it is worth the effort ;-)

It doesn't work too. I can't understand why.
More general, I'd like to extract all the variables available in a
namespace (and if I can do it, I'll can get the list of the fields).

Hi,

I'd like to add, modify and delete entry in an LDAP directory. I've
quickly read ZLDAPConnection's source and I guess that fonctions
"_addEntry", "_deleteEntry" and "_modifyEntry" can do what I'm looking
for, but I can't imagine how ! :)
I've tried a LDAPlink.addEntry('dn','values') in a dtml-call. Apparently
it work, but there nothing new in the directory :(
Have you any ideas ?


Thanks,

Same suggestion. How it works (one possible way of doing it):

Using a standard Linux installation, create a document with your data in a
Python method and safe it as a local (temporary) file (e.g. using the PDF tools
that exist for Python, e.g. "PIDDLE"). Then just do the following in your Python
code:

import os
os.system('lpr /path/filename')

This works under Windows, too. Just replace the system call by something
appropriate like "copy path\filename lp1".

It should also be possible to redirect the stdout data stream directly to the
printing device. 

I have also found some more sophisticated solutions:

- using the classes wxPrinter and wxPrintout from the wxPython package
- for Windows: using the Printer API directly with
   import win32ui
   import win32com
   ... (gets complicated)

Hi,

Sorry, there are no book of Zope, yet. Many (I think) are comming.
You can also have a look at ZDP : zdp.zope.org

Hi All!

Now and then there are strange things going on with my Zope 2.1.4/Linux
Intel installation.
Ok, here is what happens:

http://www.myhost.de:8080

raises a Zope Error (Attribute Error, getUserObject)

http://www.myhost.de:8080/manage

requests authentication and I give as UID/pwd as the superuser's pwd.
Again, strange Error-Messages.

I repeat (non-deterministic number of times) this and suddenly: everything
is ok.

What can this be??

Regards, Ingo.

Eddie,

I seems from your traceback that the user you are using to
_run_ your Zope process does not have permission to read 
some (or all) of the Zope files from the filesystem:

> IOError: [Errno 13] Permission denied: 
> '/usr/local/bin/Zope-2.1.6-linux2-x86/lib/python/App/manage.dtml'

You need to make sure that either you run Zope as the same 
user you used to install it, or change the filesystem permissions 
so that the user you are using has read access to all of the 
Zope files (and write access to the /var directory and any files
in the /var directory).

Hope this helps!

Authentication is not your problem, the user your Zope is running as
does not have permission to read it's own files.  Keep in mind that if
you run Zope as root, Zope will automatically demote itself to the user
'nobody', this is a standard practice of many servers as running a
server as root can be a security hazard.  If you want to run Zope this
way, then make sure that 'nobody' can at least read everything, and can
write to the /var directory.  

Otherwise, run Zope as a user that can read its files.

So do I.  Several people have reported this bug, but I cannot reproduce
it.  No one has been able to reproduce it or tell me how to reproduce
it, therefore, I cannot fix it.  The only thing I can tell you is that
it has to do with ZClasses that catalog themselves and that it happens
rarely and that updating your catalog allways fixes it.  I suspect it
has to do with poorly engineered ZClasses.

The method that contains this code.  You are probably experiencing some

Message-ID: <00032409234800.00783@modemcable215.47-200-24.mtl.mc.videotron.net>

HI,

How to get information about a ZClass property sheet from outdside the ZClass?

The goal is to create a "myzclass_addForm" that generate automatically the
input fields for the ZClass propertysheets.

In tried this:
/Control_Panel/Products/MyProduct
	myzclass
	myzclass_addForm
	myzclass_addPermission
	myzclass_factory

I just modified "myzclass_addForm" to add:

<dtml-in "ebook.propertysheets.common.mypropertysheet.propertyMap()">

...stuff to generate the input for each property.... 

</dtml-in>

It worked fine when I called "myclass_addForm" by clicking on the "View" tab of
the myzclass_addForm management screen. However if I try to add a MyZClass
instance from anywhere in my Zope hierarchy, I get the following message:
"Authorization failed. Retry?" and if I cancel:

"Unauthorized

       You are not authorized to access common."

I tried to change permissions and proxy of my myzclass_addFrom but it doesn't
work.

Can someone be sweet enough to tell me where I could find docs on how to access
the propertysheets elements.

Thanks

Hopefully it will be up on /. today. Hope the Zope.org servers are ready.

There is also a Zope Discussion Board at DevShed (based on UBB) which is
pretty quiet now. It might be a place to get people learning about Zope who

Hi,

if you want to hide them based on permissions, this is easy. Set the "Access
content property" to the correct value and it works. This is the way I do it
for my application, where I have browseable admin area and a public area. If
    an admin logs in, he sees the admin area too.

If this is not the case, then do a 

<dtml-tree>
    <dtml-if "id=='x'">
        display as you like it
    </dtml-if>
</dtml-tree>

Bye, Oliver

I didn't create the images, but I would not surprised if they were
created then as there was a big push to get things uploaded before
the 1st.

I can have them reupload the images to work around the problem, but I
agree that it would be much better to know what the bug is.

I've implemented a variant of Michel's suggestion. Let me explain what I
am trying to do. I'm trying to implement the
SelfServeFAQ:www.lcg.org/ssfaq (SSF),written in php3, within my Zope
website. To give a consistent look to my site, I also want to wrap the
SSF with standard_html_header, etc. So when a visitor goes to
www.mysite.com/FAQ they are really being served
/SSF/directory/index.php3 wrapped with my Zope code.

The problems come when a user clicks on www.mysite.com/FAQ/add.php3 or
some such similar link in the HTML produced by index.php3. I tried using
mod_rewrite in Apache, but found that Zope used
www.mysite.com/FAQ/add.php3 as the base for all the links in the
wrapping code. The only way I found to avoid this was to use the "[R]"
flag in the Apache RewriteRule. 

But I want SSF to be transparent to the user so instead I used
SiteAccess to rewrite /FAQ/add.php3 to /FAQ and pass /FAQ/index_html the
script name "add.php3". index_html then uses lstaffor's How-To tip( use
"Client.call( www.mysite.com/SSF/directory/add.php3)[ 1 ]" ) to embed
the PHP script call in my Zope page. In addition, I wrote additional
code in my accessRule to pass images in the PHP directory tree via Zope.

There is one inconveniences with this approach: I had to hack SSF to
remove the <html> tags and some others returned by Client.call (it
worked otherwise but, hey, I want my HTML code to be clean). But all in
all, the resources of Zope (the code and the community around it)
allowed me to solve the problem with very little modification of the SSF
PHP directory tree contents.

If there is wider interest on this I could write a How-To on it.

Michel, I take back the assertion in my private email.

I've just determined that this glitch in my
CatalogAware Journal ZClass (using a custom catalog
as per http://www.zope.org/Members/AlexR/CatalogAware)
arises whenever a user edits an instance of this class.  

Users are using the standard Zope management interface 
but I have substituted the standard Properties View 
with an "Edit Journal" View.  This is a copy of the 
Journal_AddForm method (with default values culled from 
the now existing instance).

As per #4 in the above How-To, on submission this calls 
the following DTML method which puts my publicationCatalog 
in a strange state (requiring the update):

<html><body>

<dtml-call "propertysheets.Properties.manage_changeProperties(REQUEST)">
<dtml-call reindex_object>
<p>Changes saved.</p>

</body></html>

I desperately need to sort this out before users start
making changes.  I certainly can't do an update of
the catalog on every edit of an existing Journal
instance.

Any help is much appreciated.

Cheers,
Darran.

Hello,

I intend to get from fatbrain the e-matter edition of the Learning Python

The problem is that they mention that e-matter works only on windows
platforms, and I want to know if it is possible to print the book so that
I can use it while working my computer, which does not run windows.

Thanks in advance.

What would constitute a poorly engineered ZClass?  I've seen this
problem with a ZClass that is descended from just CatalogAware,
has a few properties, and for which I've rewritten the Add and Edit
methods to call reindex_object.  I'm not sure how I could engineer
this simple class better, but I don't really understand why I have
to rewrite the Add and Edit methods to call reindex_object,
so it could well be that there are improvements that could be made.

In my case, I did not even do an update catalog.  After adding
a few additional objects, the error message went away on its
own.  (I didn't do a catalog update, because if I do that the
meta data for the id field gets completely screwed up, so I stay
well away from catalog update).

I am running under SiteAccess, and I have a sneaking suspicion my
problems orignate there.  I'll be moving the database to a
dedicated server soon and will remove SiteAccess.  If I see the
error again at that point I'll let you know.

Imagine I have a python extension, with zope id pyFetch

I want to call this in a manner similar to:

  <!--#let call_method="'pyFetch'"-->
    <!--#in sql-method-returns-href-->
      <!--#var "_[call_method]( href )"-->
    <!--#/in-->
  <!--#/let-->

But I get an error:

  Error Type: TypeError

So it seems to evaluate and call the extension without adding the
parameters.  I guess I need something like lambda in python.

Can anyone help me please?

Subject: [Zope] Newbie question: using backing files.
Message-ID: <013c01bf95b2$9320f070$afe9612f@entrust.com>

I have a situation where there are some HTML files which I do not control
that I would like to open up to access through my Zope server.  I don't want
to import these HTML files as Zope objects because these files will
frequently be edited and updated in place and I want any changes made to
these HTML sources to be immediately reflected in Zope as they occur.  I
also don't want to just use a URL to access them because a) the end-users
shouldn't be aware that they're exiting Zope scope for these items and b) no
URL could possibly point to these files since they're actually stored in a
revision control system through a "view" (in essence, a virtual local
directory tree).

So what this basically boils down to is this: I'd like to take a URL like
this...

    http://my.intranet.site/Documentation/ComponentSpecs/MyComponent.html

...and have the logic behind it conform roughly to the following pseudocode:

    1. Switch to "/viewdir/source/component/MyComponent/doc".
    2. Open the file "ComponentSpec.html".
    3. Serve up the contents of that file to the user.

The user should see no visible signs that the data comes from outside of the
Zope environment.

I've already investigated using an external method to accomplish some of
this.  For example I served up an outside file in almost exactly the way I
wanted to accomplish this using code like the following:

    def testMethod():
        s = ""
        f = open("/viewdir/[...]/ComponentSpec.html", "r")
        for l in f.readlines():
            s = s + l[:-1]
        return s

Indeed this does EXACTLY what I want.  (In any production version of
this--this was only a quick'n'dirty hack--I'd be doing some significant
caching and version checking.  But the example gets the drift across.)  The
only problem is that I can't figure out how to translate a URL like the one
I provided above into a method call like testMethod("MyComponent").  (The
documentation on these things is a bit... spare.)

So does anybody out there have any suggestions?  I'm not afraid to get my
hands dirty with Python (it being my scripting language of choice for the
past 4+ years) and I'm not afraid to learn Stupid DTML Tricks.  I just don't
know enough Zope yet to even be dangerous.

Subject: Re: [Zope] Printing from Zope.....Report writer building


I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

I haven't bought the eMatter edition of Learning Python =), but I did by the
Eff-bot's guide.  I was able to print it fine, although personally I prefer
nicely bound books to large amounts of single-sided A4/letter pages with too
much whitespace around the borders.

Also, know that some folks have had problems with eMatter's distribution
schemes, especially those with non-US installations of Windows, from what I
gather.  Luckily, I hear that fatbrain's technical support helps folks get
past these issues.

On the positive side, I do like the ability to search PDF files.

the 'address' mentioned there is the port (one of the ports) zope is
listening on. this means either you already have some process (zope?)
listening there or your os thinks that there is some process on this
port. 

in the former case look if there's one of your zope processes still
there (e.g. 'ps auxw | grep python' to list your python processes (on
linux)) or if there's some other process using it ('socklist' will
tell you if its in use); in the latter wait a little, the os will
usually grok this eventually.

We have very erratic crashes, the only commonality we can find is
volume.  When requests are low the system is awesome, but once load
starts increasing we see frequent restarts, once an hour at least.  This
could be due to people experience slower response times and breaking the
connection to attempt a reload.  From what someother people have been
saying a 'broken pipe' error in zope_msg.log may cause all the threads
to die off.  The problem here is I generated 30-40 'broken pipe' errors
and could not crash Zope.

When you run ab against it are you hitting a wide variety of objects or
the same page over and over.  I've had Zope perform great accessing the
same page repeatedly but show some strain once you vary it's diet a bit
especially when cached SQL results are involved.

What server method are you using on the sandboxes.  We use a combination
of ZServer and FastCGI connections for our traffic, with all /manage
going through FastCGI and the actual public traffic using a mix of
FastCGI & ZServer.

I can't get this to work.  When I try it all the messages come on the
screen like they should, each service that is up etc, but the darn thing
will not answer requests.  As soon as I run the exact same command w/o
strace it works.  I've also tried to attach strace directly to the
already running processes, and no luck.

As soon as I'm able to collect more info I'll forward it to you.  Is
there anywhere else I should be posting this information?

Please send any new info to all of us. I could not get strace to work
either but what is puzzling, I will get the problem even on a no load
site.

Hi,

As I didn't receive any answer from my previous message, I guess it wasn't very
clear.

How can I get a list of property.ids, property.types of a ZClass propertysheet
from outside the product containing my ZClass.

I tried a lot of things but i hit a wall.

Thanks

This should be easy, if you can get Zope read access to the files...

Use Jonothan Farr's Local File System Product.

I don't know what you mean by "python extension" -- is this an ExternalMethod? 
A PythonMethod (it doesn't look like one)?  A method of a class defined in a
Python product (I don't see an instance anywhere)?  I'll assume an
ExternalMethod, because it looks most like your stuff.

Assuming you have a folder, which contains/acquires an ExternalMethod,
'pyFetch', defined as taking two parameters, as above (I'm assuming from your
description that you have the EM with a different ID than its underlying
function -- that works, but for clarity I would generally avoid that).  This
folder contains/acquires some method, 'list_hrefs', which returns a list of
objects which have an attribute, href.

In a DTML method contained/acquired by that folder::

  # I'm using a PythonMethod which returns a list of dicts,
  #  so I am using the 'mapping' argument to get its key/values to
  #  look like attributes.

  <ul>
  <dtml-in list_hrefs mapping> 
    <li><dtml-var "this().pyFetch( href )"></li>
  </dtml-in>
  </ul>

That works for me -- I get an unordered list of the results of calling pyFetch()
on each href "attribute".

Message-ID: <01b401bf95da$0c434e90$29a8efd0@atinucleus.com>

I use an external python function to return the SQL result set.

here it is: ( I reference it as an external method called getRes in Zope)
---------------------------------------
def doPySQL(self, zQry) :
    tvar1 = 'res=self.'+zQry
    exec tvar1
    return res._schema.items()
----------------------------------------

This function returns a set of key/value pairs that are the column_name/column number

Here is the dtml document I used for testing: (UserSettings returns info for a user)

-------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=getRes('Your_Query_Name_Here()'))">
<dtml-var "_.len(t1)"> Columns<br>
<dtml-var "_.str(t1)" html_quote><br><br>
<dtml-in t1>
<dtml-var "_.str(_['sequence-key'])"> = <dtml-var "_.str(_['sequence-item'])"><br>
</dtml-in>
<br><br>
</dtml-with>
</body></html>
______________________________

This code will give you a listing of column names and values
sorted by column name for every record returned by the SQL Query:

--------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=Your_Query_Name_Here(),t2=getRes('Your_Query_Name_Here()'))">
<hr>
<dtml-in t1>
  <dtml-in t2 sort=sequence-item>
    <dtml-var "_['sequence-key']"> = <dtml-var "_.getitem(_['sequence-key'])" html_quote><br>

Look at how Zope's management interface does it
($ZOPE_HOME/lib/python/OFS/properties.dtml).

to Garden Gnomes, is there some way that I could index every site listed in

You allready have a service that is running on a port Zope wants.

Zope wants 8080 (for web) 8021 (for FTP) and 8099 (for the monitor).

It's just a suspicion, and as I noted in my previous mail I cant tell
you constitutes a poorly engineered ZClass because I can't reproduce the
bug.  By 'poorly engineered' I mean both the possibility that the bug is
manifest of the user createing the ZClass, _or_ that the ZClass
implementation is broken.  I did not mean to point fingers.

Can you reproduce it deterministicly?

Because when you change an object, you must inform the catalog that the
object has change so it can update its indexes.

This is because one of your new objects filled in the missing hole, it
may have made the problem go away, but it didn't fix it.

This has never happened to me, can you reproduce this deterministicly

What I need to fix this is a way to reproduce it.  If you can do this,
then I need your help.  I would like to see your product, but first I
have to make sure that I *can* debug this using your product.  Your
produce needs to be self contained (not dependent on subclassing python
code I don't have) and must not use any relational database stuff as I
cannot reproduce your database environment.  In other words, if you can
drop your product into a clean Zope out of the box and reproduce this
problem, then you _are_ then man.

lpr -P HP4050_raw myfile.pdf works fine.  So I was just writing an
external method to slap that document to my printer.  But I stopped
thinking  about this because we decided online delivery of all documents
was okay and other things took priority.  

If you wanted to print more than just plain text, I guess the mime type
would have to have a "printer" application sort of, or filter just like
they have "viewers".

Has 'weighted' banners.
If you have 2 banners, each with the nromal weight of 1, each will
appear roughly 50% . If you assign a wieght of 2 to one of them, it will
appear roughly 67% of the time.

Our users were having problems accessing our site today. On examining the login

and everything was back to normal again.
Any ideas why these variable values were the same across multiple browser

Yes.  It lives in the zope extensions directory though - blame lack of sleep.

Problem: In real life, I don't know that I'm calling pyFetch, it could be 
pyDontFetch or pyGoToSleep etc (the "#let call_method" is in another DTML 
method and there are a few alternatives).  All I know is that it shares 
the same signature.  Works fine if you call it directly.

Is there a better method than the equivalent of

  <!--#if "call_method=='pyFetch'"-->
    <!--#var pyFetch( href )-->
  <!--#elif "call_method=='pyDontFetch'"-->
    <!--#var pyDontFetch( href )-->
  ...


Thanks

index_html is a 'DTML Document' and other documents are actually 'DTML

Zopistas,

how do I pull this off?

<dtml-in "objectValues(['Folder'])">
  <dtml-with sequence-item only>
   <dtml-unless noshow>
    do something
   </dtml-unless>
  </dtml-with>
</dtml-in>

I've tried messing around with the _ variable, with little luck.

This is part of a menu, and the thing is, even if I don't want to show
the folder in the menu, I don't want the menu to disappear when I'm in
the folder.

thanks,

Ethan Fremen

Hi everyone,

I'm hoping that someone on the list has some experience with NetWare's NDS.
The school district where I work is a NetWare shop with the exception of
the Web server which is running Linux. A couple of my students and I do the
Web stuff on the side.

Starting in the fall, I'd like to begin using the PTK and authenticating
users against our NDS directory. I'm wondering if anyone can tell me whether
Novell's recent release of their eDirectory product for Linux will affect
how we approach this. Are the existing LDAP Zope products sufficient?

Looking for some NDS Zen,
Tim

Some good news at last ...

When I set DEBUG in asyncore.py to 1 so I could view the lists going into
select, ZServer stabilised and hasn't crashed since. Smells like a race
condition and somehow the extra time it takes to print the list contents
stabilises things.

Still I cannot understand how the child process causes the supevising
(zdaemon) process to die too.

If your printer is setup is fine you can write the zope output to a file and
print it  using an external method 
If you can name your printale docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
pos = find(self.__name__, ".prt")
if pos >= 0:
redt = PrintJob(r)
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better
bet

This might be a seperate problem than The Mysterious Segment Violation. 
Can race conditions cause SEG faults? , I guess they can like any other
piece of code.  but I would expect a race condition to just spin the
process.  Can someone who I've spoken with about their SIGSEV problem
reproduce Pavlos' cure?

This makes me think it's a different problem also.  I get the feeling
you should be able to reproduce this problem on a fresh checkout on your
platform since it's so low level.  Can you check that?

The reason depends on how it didn't work.  Did it give you an error and

Interbase has gone open source, and the 6.0 beta version ( Windows,

www.interbase.com.

Looking at the contributed downloads, they have a Perl DBD driver, an
AOLServer database driver for Linux, and a port of the ArsDigita
Community System.

Pity there is no Zope support except from ODBC in Win32 - and that is
extremely unstable in my experience.

Hello Darran,


I created a new CatalogAware ZClass in Zope 2.1.6 with a custom Catalog 
name based on the information in the Howto.

It works fine so far. I didn't have any similar error when I updated the 
ZClass properties a couple of times.

If you can trap this elusive ZODB error please let me know. I'll update the 
howto if it's related.


Cheers.

Hello,
I have created a Zclass to publish FDF data for Adobe forms that can be used to
fill forms from zope (i.e create forms over the web). How can i get it added to
the contributed list ?. Is there a reveiw process to undergo ?

Hi, I'm hoping to get some feedback to a question I've had about whether
making ZClasses Catalog Aware is a good idea or not. Below is a my question
I asked and a few ideas from a response I received, can anyone
validate/invalidate any of these statements?

kh

Question:
------------------
Is it good practice to simply make ZClasses Catalog Aware by default, or is
this something that should only be done when necessary?

Response
----------------

 - Object cutting and pasting does not work properly for CatalogAware
 ZClasses. Is this a problem for you? Note you can still copy, paste and
 then delete the original object.

 - CatalogAware ZClasses look slightly more "fragile". I've seen posting
 about (fairly elusive) errors in Catalogs with such ZClasses. Note I never
 experienced them firsthand.

 - You could first create a base ZClass, then subclass it when creating your
 actual ZClasses. This base ZClass could include common stuff such as
 CatalogAwareness. Then if you change your mind you just need to modify the
 base ZClass. There is a way to change the base classes for a ZClass, though
 it's a hack.

Get a user name at the Zope site. Publish your product there. Someone at DC 
will approve it, and it will be on the official list.

Pretty easy. :)

How do you do that? That is my problem. Sometimes I forget a base class 
other times I have too many. Can someone write a How-to?

Subject: [Zope] Some basic questions concerning ZClasses
Message-ID: <00032518334200.08192@promotor>

I've just started to work with ZClasses. They are really cool. But I am running
into some problems:

I added a folder to my ZClass. Let's say the folder contains images. Using the
images from the folder in my ZClass methods works fine. But like all other
ZClass "internals" (methods etc.) the folder (correctly speaking: its
instance; or is there no seperate instance of the folder???) is invisible to the
management interface.

Is it possible to make a folder visible in the management interface so that
a user can enter additional images? Same with dtml methods/documents ...


Is it true that the methods of a ZClass don't open a new property namespace for
each instance? If I change the property of a method in one instance it seems to
be globally changed.

How can this be solved?


Thanks in advance

Joachim.

Message-ID: <Pine.SUN.3.96.1000325132704.16062A-100000@grendel.csc.smith.edu>

Hi all--- 

I'm trying to modify my copy of the SimpleURL product, and I need some
help. SimpleURL defines a property Sections within URLDirectory, where
each line is a section within a URL list. I've added another property to
my URLDirectory--- SectionDescriptions. I want to generate a list like
this:

SectionName1 (link)
  SectionDescription1
SectionName2 (link)
  SectionDescription2

I have the following code in the index_html of a URLDirectory instance:

<dtml-in Sections>
	<dtml-let  section=sequence-item>
          <A HREF="section_list?ts=<dtml-var 
"_['sequence-index']">"><dtml-var
section></A> <br>
	</dtml-let>
</dtml-in>


Now I know there has to be a way to modify that so that I can display the 
sequence-indexth element of the SectionDescriptions sequence. What am I
missing here?


And a design question: my URLDirectory is already fairly large; I may want
to create folders within it for each section. How would I adjust the
method above so that it looks to subfolder properties to display the same
information?

Message-ID: <4.3.2.20000325123830.00b9c100@tradingconnections.com>

While I still have the training wheels on, I've been trying to be careful 
to understand the difference between DTML Methods and DTML Documents. I 
thought I was doing OK until I noticed this about the management interface 
(when looking at a folder):

There is a tab for Properties but none for Methods
The tab for Contents contains Methods as well as Objects

So either I don't really understand DTML Methods vs Documents, or the 
management interface should, to be consistent, also have a Methods tab 
instead of lumping methods under Contents. I'm not complaining, just trying 
to figure out the tricks so I can take the training wheels off.

Hi,

after I settled my problems with the Zope authentification system and
dsicovered some nice tricks about Zope, with some help of some very gentle
people of course, I have another problem.

How can I allow a certain role to add local roles to an object? Which
permission do I have to activate, that this is possible? At the moment I have
solved the problem with a Manager proxy role, but I like to live without proxy
roles.

I have kind of a stupid question about sockets.  When starting zope (using
z2.py -D) I get:

(Except no monitor, obviously).  Using -m with other socket numbers

FreeBSD 3.4, Zope 2.1.4, running as root.  Any ideas what to try?  I would
like to use the monitor, if just for the coolness factor.

Note that what you're describing isn't really part of ZEO, it's really
more in the realm of what is already in Zope.  Thus, if you're eager to
add such a feature, you already have what you need.  Start tinkering
with the transaction machinery and see how you can extend it.

You asked one of the most tricky questions for beginners. If you look in 
the mailing list archives you will find the answer, but here my attempt:

I think of DTML Methods as functions that work on the folder they are in. 
Think about it this way: A folder is a class, then all DTML Methods are 
methods of the class Folder. They contain no properties other than id and 
title.
DTML Documents are on the other hand classes as well. So a DTML Document in 
Folder is like a subclass of the class Folder. Since DTML Document is a 
class, it can contain properties, while DTML Method does not.

Also, if you say: <dtml-var title> the DTML Method will return the title of 
the folder, whereby DTML Document will return its own title. That makes 
perfectly sense knowing the above definition.

How do I use them? Whenever DTML is called directly from the browser (like 
a link, or typed in  URL) I use DTML Documents. Whenever a document or 
other object calls DTML from inside I use DTML Methods.

I hope I did not confuse you. Don't take it as a major drawback to not 
completely understand the differences. It took me well over a month.

Regards,
Stephan

you can write the zope output to a file and
print it  using an external method 
not the cleanest way but works :
If you can name your printable docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
----snip snip --------
pos = find(self.__name__, ".prt")
if pos >= 0:
 PrintJob(r)
--snip snip----------
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better.
Another idea that I have tried :
inherit from DTMLDocument and create a new object type that will send itself to
the printer at the end of processing
 embed latex with dtml  and send the results to the printer using pdflatex.
There are some cool tex macros called context written by hans hagen that 
  can be used to create rich documents

How did you save the version? Did you click on the first button you see when
you bring up the Versin object in the management interface, or did you
actively go to the Save/Discard tab, where you can enter a message and then
save or discard the change?

To make a Folder show up in the ZClass instance, you should create it from
the ZClass_add method. For example, if your ZClass is called Foo, in the
method Foo_add, you could put a line:

<dtml-call "manage_addFolder('MyFolder')">

Then, every instance will have a folder called MyFolder in it.

Same thing applies for DTML methods/documents. Check out KM|Net News if you
want to see one way to provide default documents that the user can change.
KMNN also provides a way for the user to revert to the default.

Your properties should be stored on ZClass propertysheets. Then the
properties can vary from instance to instance.

Message-ID: <0003251501490F.21205@scorpio.redspice.com>

ok  so
I am trying to export a folder using import/export
I give an export id and click on export and I get an exception
however if i give an import file name and click on  export  I get a
filename.zexp  in the var dir. Isn't this rather confusing.  Do import and
export have their own
zopish meanings ?
I am seeing really weird stuff in 2.1.4  cant wait to upgrade to 2.1.6

given any thought to a Pike compatible interface to Zope?  It's a cool

I hope you have got your answer ,  any way my 2 cents
ssi pales in comparision to
dtml. dtml makes template programming a breeze.  You will have to learn the
syntax and ssi statements have their equivalents in dtml and more. But zope is
best for dynamic stuff.   For static pages  I would stick with the http server.
For your problem I see coding some dtml to replace the ssi and refer to the
external cgi just as usual for creating the image dynamically.

I was just looking at that earlier today. I was thinking that it might be
fun to make some Pike-compatible stuff. Also, it might be interesting if we
can set up a preferences system on top of LoginManager that is compatible
with the UserLand spec.

Mmmm... interoperability.

I looked briefly at the XML-RPC spec this morning. It certainly seems
plausible to create Pike compatible interfaces for specific products. Zope
and Frontier work pretty differently, but from a content-writer's
perspective there does not need to be a difference.

The people who maintain the _other_ Pike (http://pike.idonex.com/) will
be happy about this -- not.

Why can't people do a little name research before they hijack somebody
else's name for their project? This new Pike will only hurt the original
Pike's reputation, possibly even forcing the latter into changing its
name.

Pike is the C-like, interpreted OSS scripting language that powers
Roxen, a web/app server that competes directly with Zope, as well as
this Manila/Frontier thing.

I'm sorry, the corrected text above is what works. What never works is
<dtml-with sequence-item only>.  The error I get with <dtml-with
sequence-item only> or <dtml-with _[sequence-item] only> are:

Do you see what I was trying to do?  I wanted to see if just the
sequence-item had the boolean attribute "noshow"

Ethan,

Try something like (tested, but not in this situation, i.e. I use it a lot
and it works YMMV):

<dtml-with "PARENTS[-1].net" only>
  <dtml-in "objectValues(['Folder'])">
    <dtml-in aq_explicit only>
      <dtml-unless noshow>
        do something
      </dtml-unless>
    </dtml-in>
  </dtml-in>
</dtml-with>

| Note that what you're describing isn't really part of ZEO, it's really
| more in the realm of what is already in Zope.  Thus, if you're eager to
| add such a feature, you already have what you need.  Start tinkering
| with the transaction machinery and see how you can extend it.

Except at the ZEO level, the conflicts must have been resolved.
I only want to replicate the state of play at the ZSS end.

Otherwise I could alter ZEO to take a list of ZSSs and do a 'broadcast' and
have them all do the same work (hoping like crazy that all transactions
arrived at all servers in the same order). Then I would have n copies of the 
primary ZSS. Failover from this point is almost trivial. 

The other option is to get the ZSS to forward transactions in the order
IT gets them and send them to a list of servers it knows about. This is
slightly cleaner, since all of the Zope machines don't need to know
about all of the ZSSs.

The other major problem is, that if I do this work, I will be unable to 
contribute it back to the project for some time (if ever). I don't really
have the facilities at home to be able to do ZEO type work, my current
employers (where I have more available resources) like OSS, but, tend to 
treat it as a code repository, rather than a symbiotic relationship.

netstat -a should tell you what ports are being listened to.  try 
./start -m '9898'
and if it works, well, then you've probably got something listening to
the monitor port.

Note that while http can be virtualized (listen on selective IP's),
monitor and ftp cannot, so you have to pick your ports accordingly.

Try this (untested), assuming the name of the method you want to call is stored
somehow in the variable 'methodName'::

  <dtml-let methodToCall="_[ methodName ]">
    <dtml-in list_hrefs mapping>
      <dtml-var "methodToCall( this(), href )">
    </dtml-in>

Brad Clements has done a bunch of work on melding Python with NetWare -- he was
to present a paper on it at the last Python conference, but couldn't get there
due to weather.  His paper was part of the procedings, anyway, and may be online
somewhere under www.python.org.  His e-mail address is bkc@murkworks.com.

I think I even remember reading that he had Zope up and running as an NLM.

Subject: [Zope] Returning sequences of values with External Methods
Message-ID: <38DC6718.5080501@messagemedia.com>

Currently, I am making a lot of external methods, and I would like to 
use one like this:

<dtml-in methodname>
  <dtml-var foo> <dtml-var bar>
</dtml-in>

So basicly, I want to return a list of named values (a dist of 
dictionaries)? Are there any pittfalls you guys can see in doing this? 
suggestions?

Should I make it a Product?

Subject: [Zope] Project proposal: The Gestalt System (using Zope)
Message-ID: <38DDD362.22728102@bigpond.com>

The Gestalt System project aims to develop a free, Open Source,
object-oriented software framework which makes use of other free, Open
Source software tools for the purposes of managing, analysing, and
reporting on quantitative data in a manner which is suited to modern,
networked computing environments in which processor, memory, and storage
resources are abundant but time is scarce and requirements are forever
changing. 

The Gestalt System may be of particular interest to Zope users because
we propose to use Zope to provide some important aspects of the
project's
infrastructure.

Full details of the project proposal can be found in the Gestalt System
Manifesto which is available at http://gestalt-system.sourceforge.net

I was very confused about this  - the only Pike *I* knew of, is the core language of the Roxen webserver (www.roxen.com), which has been going for some time. As the Roxen team are about to shift version 2 of their server it seems like some lawyers are going to get some bunce here :(

Subject: [Zope] Accessing ZSQL connection from external method
Message-ID: <v04220801b503b1dd8153@[134.76.23.194]>

Howdy!

I'm making heavy use of MySQLdb in my external methods. Now I just 
realized that ZSQL-connections are kept open permanently and it would 
save a lot of time if I wouldn't have to open a connection each time 
my external method is invoked but use the already existing 
ZSQL-connection instead.
My question: How can I access a ZSQL-connection (ZMySQLDA) from an 
external method?

--Ragnar

P.S.: I benchmarked MySQLdb and found that opening a connection took 
1.2ms on my systen whereas a very short request for authentication 
took only 1.1ms. So beeing able to use an existing connection would 
result in about 100% performance gain (at least at first glance).

Subject: [Zope] anonymous Products?
Message-ID: <38DE0A95.CF7CA9A7@imeme.net>

Zopistas,

I need to have a dtml-method that does manage_clone,
manage_changeProperties, and manage_users.

It has to let an anonymous user do this:  I have to set up accounts for
people automagically.

I cannot seem- either with a product or just a straight method- to give
it the permission it needs to be called anonymously.

If anyone could give me a hint as to how to achieve this, that would be
great.

I looked at http://yyy.zope.org/Register/register.html , but I cannot
seem to get the dtml code for the actual new-user-maker.

Answer: make sure REQUEST has confirm and roles:list properties (the
latter isn't absolutely necessary, but you'd just have to set it later
anyway.)

Subject: [Zope] Performance Testing / Expections
Message-ID: <20000326232738.A30471@bob.sesgroup.net>

Ok,

I know it has been asked a couple of times before on the list, but
there hasn't really been any absolute conclusions on the type of
performance to expect from zope and/or how to tweak it for the best
kind of performance.

Over the last two days I have been doing some testing and would like 
to hear on opinions if these results are similar to other peoples.

Firstly the machine specs are:

PIII 450Mhz
128Mb 
IDE Harddrive

Running Debian Potato

Zope is running through Apache with PCGI.

All tests were run using ab.

First I tested apache to see how fast it was as a benchmark.

1000 requests, 25 Concurrent.

/usr/sbin/ab -c 25 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

Results:

384 requests per seconds (rps). Avg wait: 54ms. Max Wait. 83ms. Throughput: 20MB/s

1000 requests, 1 at a time.

 /usr/sbin/ab -c 1 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

425 rps AvgWait: 2ms MaxWait: 3ms Throughput: 21MB/s

The I tested the same document servered statically through zope. (From zope's root)

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/testemc"

42 rps Avg Wait: 514ms MaxWait: 743ms Throughput: 2MB/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/testemc"

45 rps AvgWait: 21ms MaxWait: 29ms Throughput 2.3MB/s

Next on line was a moderately dynamic page. Dtml only, no DB or Ext. Methods.

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/sesgroup?cu
rrentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/siteinfo/index_html?"

4.97 rps AvWait: 4.4s MaxWait: 5.6s Throughput 21kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/
ecom2/sesgroup?currentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/
siteinfo/index_html?"

5.09 rps AvWait: 195ms MaxWait: 198ms Throughput 22kb/s

Then finally testing a page with the same amount of DTML complexity but
some external methods which call a database using pygresql

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps  Avwait 16s  MaxWait 20s Throughput 19.51 kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps Avwait 768s MacWait 789 Throughput 19.55 kb/s

In summary serving straight of apache is very fast, and doesn't suffer if 
multiple people access the site at once.

Static Zope (which you wouldn't really do anyway) was acceptable speed and
didn't really suffer too badly if there were multiple accesses.

Dynamic Zope was fair in speed, but proably still fast enough, at least for
my site anyway. It started to suffer in a bad way with multiple accesses, 
up to 5 sec response time.

Highly dynamic Zope was very bad in rps and hopeless more multiple access.

Now I have only been in this game I a while so I don't know how critical 
the multiple access thing is going to be. I am expecting at most 1000 
visitors each day (say a 10 hour period). So 100 visitor each hour shouldn't
cuase me any problems at the moment.

I guess how I would like to know if anyone out there knows how to improve 
this performance at all. Can I throw memory and processors at it and make
it go away? Obviously there are some things in the highly dynamic bit
which I will need to speed up, however how can I make just normal
dtml execute faster? The prospect of ZEO has certainly helped in this
area but surely I must be able to sqeeze some more performance out of this
machine.

Thanks in advance.

1. Generate Expires headers for your pages, and maybe handle
If-Modified-Since headers too (see OFS.Image.File for an example of the
latter.)  This lets the browser cache results of yor pages, which won't up
your requests-per-second but will reduce the number of requests you have to
handle.

2. Cache results of dynamic pages and then serve that up instead.  This can
speed things up by a factor of 5 for pages that are only a little dynamic.


I'll follow this up in a short while with an example of generating Expires
headers in DTML.

The following dtml code will tell the browser that the page expires one hour
in the future:

<dtml-call "RESPONSE.setHeader('Expires', _.DateTime(_.DateTime().timeTime()
+ 3600).toZone('GMT').rfc822())">

Wild idea: Do you ever get errors when you try to compile a big, big
program, specifically the Linux kernel?  It seems as if a large number
of seemingly perfectly functioning PCs have memory errors that only
show up under specific, not well known access patterns.  Compiling a
big program is a process that can exhibit these error prone
patterns[1][2].  Perhaps Zope under load causes the same access
patterns?

[1] This is not an urban legend.  I have seen it.
[2] Search for gcc and signal-11 or sigsegv.  There are a couple of
    web pages out there about this.

I get them constantly when recompiling Mozilla, which is a daily task almost.
And bad_slab_magic, and random segv's.

I'll be running a good memory stress test soon, to see if I can pinpoint the
offending Mem. bank.

You can embed SSI within Zope. I'm currently writing a How-To on it.
Depending on how complex your inclusion is, you may be able to get away
with using Apache rewrite rules. If you want to embed the SSIs within
your Zope pages, you can resort to using SiteAccess and a call to
Client.call. Take a look at the thread "How to serve PHP within Zope"
for a more detailed explanation of what I mean. I should have the How-To
finished soon. If you are in a rush, I can send you a draft.

Well, that is food for thought today. If anyone has some really good
analysis of this (since this is my first time using AB) that would be
great.

netstat -a shows only ssh, http, smtp, sunrpc, and syslog sockets open.  
Nothing too wierd.  Like I said, using other socket numbers (e.g. 9898)
doesn't seem to fix it.

I can offer you an NDS user folder if you're running Zope on Windows or 
NetWare itself. For Linux, I suggest using LDAP

Message-ID: <Pine.LNX.4.10.10003261217150.15096-100000@odeon.net>

	Greetings,

	I've got a form that has three fields.  One for year, one for day,
	and one for month.  The selection parts of the form are similar to
	the following:

   <select name="date_mm">
    <option value="01">January          
    <option value="02">February     
    <option value="03">March
    <option value="04">April     
    <option value="05">May     
    <option value="06">June     
    <option value="07">July     
    <option value="08">August     
    <option value="09">September     
    <option value="10">October   
    <option value="11">November     
    <option value="12">December    
   </select>


	What I'm trying to do is pull the 'date_mm' (along with the other
	two fields, 'date_yy' and 'date_dd') into the namespace area so I
	can do something like:

  <input type="hidden" name="event.date" value= \
    "<dtml-var var_yy>-<dtml-var var-mm>-<dtml-var var-dd>">

	I would expect that I can use something like:

  <dtml-call "REQUEST.set('var_mm', 'date_mm')">

	However, that doesn't work like I'd hoped.

	Any help would be greatly appreciated,

	Jeff

Subject: [Zope] dtml-tree question
Message-ID: <20000326221801.A17865@owl.rhein-zeitung.de>

Hi, 

I have a problem with dtml-tree. But I think that is just a problem I have,
cause I don't completely understand the dtml-tree thing.

I have the following dtml code snippet

<dtml-tree skip_unauthorized=1 branches_expr="objectValues('Folder')" sort="order">
    <dtml-if "'index_html' in objectIds()">
        <a href="<dtml-var tree-item-url>" target="contentframe"><dtml-var title_or_id></a>
    <dtml-else>
        <dtml-var title_or_id>
    </dtml-if>
</dtml-tree>

Well, I traverse my folder structure to build a nice dtml-tree from it. So far
the insertion of links, the if-clause of the dtml-if statement, works really,
really fine. But I also want people to be able to click on the elements that
are part of the tree, so that they don't need to click on the plus signs but
can also click on the text next to the plus sign. This is the else-clause in
the dtml-if statement. But everything I tried didn't work. 

Is is solveable? And how? Or do I have to build my own tree using a recursive
call of a dtml-in loop?

Bye, Oliver Andrich

P.S.: For all of you who have seen my questions about users, roles, and so on.
I like to tell you, that I am writing a HOWTO on this, so that people don't
have to dig into the information and bother people with questions, as I did.

Looks to me like you're close...

<dtml-call "REQUEST.set('var_mm', date_mm)">

Note that there are no quotes around date_mm. Assuming that this DTML is in
something POSTed to by your form, date_mm will be available in the
namespace, and you can use it like a normal variable.

Your question is not quiet clear, but I will make some assumptions and then 
try to answer it:

I assume you want to do that all in the same file, without sending a form. 
In this case what you want to do is not possible, because you ask the 
server to know something which does not exist yet.

A form is created in the moment the user submits it. So here is how you do it:

FILE: someForm

...
<form action="someAction">
   <select name="date_dd">
      <option value="01">01
      <option value="02">02
      ...
   </select>
   <select name="date_mm">
      <option value="01">January
      <option value="02">February
      ...
   </select>
   <select name="date_yy">
      <option value="1999">1999
      <option value="2000">2000

<dtml-call "REQUEST.set('eventDate' , date_mm+'/'+date_dd+'/'+date_yy)">

So you combine your date AFTER the form is transmitted. I cannot think 
about a case, where you need it differently. If you have one, you should 
revise your design, since weird syntax is mostly due to bad design.

Ben,

Hi...

This topic is probably better suited for the main Zope mailing list so I
moved my reply to it there.

Err... we'd all love to see better docs written for this process.  Maybe
you can write them once you get it done.  :-)  No, Zope does not
necessarily need to be installed from source, but I think the MySQLdb
stuff needs python include libraries.

Can you give more specific questions about your problem?

Some hints anyway:

 - the MySQL development libaries need to be installed on the machine.
 - python 1.5.2 libraries should be installed on the machine

Yeah I am currently thinking of the best way todo this. I guess I now reach
another point. Does anyone know how to make External Methods persitent, or
would I have to store cached information on the filesystem. Does ZCache work
for External Methods, are there any plans todo this? I don't mind writing
code for ZCache todo this if the current framework easily allows this.

Thanks,

 I usually  create python classes instead of plain external methods and
instantiate them  as zclasses. This way I can cache information with inthe
python class as class members. If there are hooks in the zope framework to do
somthing similar (ie make use of zcache etc) please post

Not convinced that's it tho.

Side-note:  I've patched ZServer/medusa/asynchat.py line 255 - the 'first'
method - to check if self.list actually has anything on it before
returning:

        def first (self):
                if self.list:
                        return self.list[0]
                else:
                        return None

Since I did that, I haven't been able to reproduce the crash.  I doubt
that's the problem as such - I'm still leaning toward a race condition
somewhere - but the fact that it hasn't crashed since then is curious...

Oh, and strace'ing and adding debug and so forth seems to cause the problem
to display subtly different behaviour - which makes me unhappy...

Hi there,
I've got an 8-character string, say str='12345678'. With
<dtml-var str> ofcourse I get 12345678.
How can I display only part of it ? Say the first 4 chars
(1234) or the next 2 (56) or the last two (78).
In python I know this can be done with something like
str[:4], str[4:6] and str[6:].
Any help ? (Hope I didn't sound too newbish !).

Subject: [Zope] Passing data to/from Python
Message-ID: <NCBBJGNEKLKGLMECHMLGIEFOENAA.wexler@ccr.jussieu.fr>

Dear Zopistas,

I am in the process of learning about Zope, and trying to
determine whether to make the switch from pure Python CGI
scripts. If someone could answer the following questions (and I
apologize, as it will probably seem naive), it would really help.

Let's suppose I have a page where the user queries a data base,
for instance a telephone directory. The telephone directory is in
an Excel file. At present, I have a CGI script that opens an
ODBC.Windows connection, executes an SQL query, and outputs the
results (names, phone numbers) as an HTML table using "print".

What is the best way to do this in Zope? Here are the points that
I don't get:

1. It seems that the only way to establish a DB connection is
through Gadfly. There are warnings everywhere that Gadfly is
inefficient. Therefore, I want to use ODBC (ODBC.Windows), like I
did before. How?

2. I might eventually need to do complex calculations on the
retrieved data, so I would prefer using Python code in an
external method, rather than a DTML method. In order to get Zope
to accept the line "import ODBC.Windows", I had to copy the ODBC
and DateTime directories from my regular Python installation
(PYTHON/lib) to ZOPE/bin/lib. But then, when I try running the
script, I get one of the following problems:

   a. If I go through authentification, the script runs, but I
   cannot establish the connection to the database.

   b. If I type in the URL of my search page directly, without
   authentification, I get a Zope error: "initialization of
   module mxODBC failed
   (exceptions.AttributeError:mxDateTimeAPI)".

Is my ODBC.Windows installation wrong, or do I have a more
fundamental problem?

3. What if my Python function in my external method wants to
return information to my DTML method? For instance, how do I
return a Python list, and what do I do in my DTML method to
process it (e.g., output a line for every member of the list)?

4. The way I call my Python function now is through the <form
method="POST" action="search"> tag, where "search" is the
external method ID. The form has a field called "name", and my
Python function has an argument also called "name", and so it
recuperates the string that was entered in the "name" field. Can
I pass the "name" as an argument to a DTML method?

If these questions have answers, I would really appreciate them.
Otherwise, if I'm completely off-base (for instance, if I'm
thinking in Python terms and not in Zope terms), please point me
in the right direction!

Thanks in advance.

Nonono.... ZOPE uses the Gadfly db to store "zope objects".  It can also
connect to other DBs, and access them via SQL methods.  There are a number of
DB interfaces, including an ODBC interface.

afaik, you can simply return a list.  As for iterating through the list, you
would use <dtml-in myMethod> stuff goes here </dtml-in>

All fields passed in a POST are available via the REQUEST.form map.  Also, so
long as they don't match the name of other objects in the namespace, you can
access then directly.  So, your 'name' field will be accessible:

<dtml-var name>  <-- assuming you don't have any other objects called "name"
<dtml-var "REQUEST['name']">    or
<dtml-var "REQUEST.form['name']">

Gadfly is just one of  the db's you can use. The aquaduct product family gives
you many options
 look at http://www.zope.org/Products/DA/ZODBCDA for the ODBC
adapter.  This is defenitely the easier way

You can do quite a bit with dtml unless of course you prefer python  and
sometimes it is easier to do stuff in python,  dtml is not a replacement by
any means

return a list and process it using  <dtml-in > which behaves  very similar to a
database cursor 
>  Can

Absolutely with the dtml  programming you can do the same things and more 
All the form variables show up in the REQUEST object and become part of the
namespace in your script,you can use them like any other variable in the
script

There's an ODBC database adapter for Windows machines.  It does not work
under UNIX.  The Sybase DA works against MS SQL Server 6.5 and below
from UNIX.

Look under "Downloads" on Zope.org.

Also read the ZSQL User Guide.

Hmm.  I've never seen ODBC.Windows.  We've punted on supporting ODBC
under UNIX, and we're now supposed to be contracting out to some other
folks to provide it for us.  Not sure when this will happen.  You can
try to write your own ODBC DA for UNIX/Linux.  There is a HowTo on
writing a DA someplace out there that Chris Petrilli wrote.

external method named "pyfunction":

def pyfunction(self):
   return ['1','2','3']

a dtml method that uses pyfunction:

<dtml-in pyfunction>
   <dtml-var sequence-item><br>
</dtml-in>

Should output:
1
2
3

If you use an external method to handle the form input, you should be
able
to get at its attributes by looking in REQUEST ala:

def myformhandler(self, REQUEST):
    a = REQUEST['a']
    b = REQUEST['b']

where 'a' and 'b' are form field names.  This can also be done by:

def myformhandler(self):
    a = self.REQUEST['a']
    b = self.REQUEST['b']

Hey Mark,

This is your lucky day... Zope does this without even blinking... I 
would say (and without starting a flame war) that Zope's ability to 
easily connect to databases is one its best features. To the 
questions...

1) Gadfly is the example. You connect to anything that there is a 
ZSQL connection product for (Oracle, Sybase?, PostGreSQL, MySQL, 
Gadfly)

2) You get back the data and can do anything you want with it. You 
can parse it, calculate it (although you might want to look into 
doing some of it in SQL) or just spit it out. Authentication has 
nothing to do with what you do with the data.

3) It is easy in DTML, just do a <dtml-in> to go over the list.

4) Yup. You build a form and send that form to a DTML method that 
processes the form. If you are super slick you have it in the same 
DTML method.

Don't worry about thinking in Python terms. I came from Python.. 
thought Zope was going to be easy, found out it hard than studied up 
a bit and now respect it. There are a LOT of things you can do in 
Zope, most of them "like" things you do in Python, just stated a bit 
different. The DTML reference guide is your buddy. You read that and 
come back here when you are truly stuck.

Now go Zope...

:)

Ok.. my mistake.. sorry.... thanks for correcting me.  I was under the
impression ZOPE stored data in a db, using gadfly as the default, and it was
refered to as ZODB for convenience.

Thanks for clearning that up for me.

Subject: [Zope] Problems with adding ZClass instances
Message-ID: <14558.57262.760790.737744@antares.int.plain.co.nz>

I'm have problems with a ZClass I'm working on that uses Folder as
it's base class and is supposed to install a set of default methods
when it's created. The trouble is that it won't when the webDirectory
is created, but it will when I invoke the same method from a tab afterwards.

Here's the body of webDirectory_add:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-if createDefaultMethods>
   <dtml-in "default_methods.objectIds()">
   <dtml-try>
      <dtml-call "manage_delObjects(ids=[_['sequence-item']])">
      <dtml-except>
      </dtml-try>
     <dtml-call "manage_clone(
            _.getattr(default_methods, _['sequence-item']), 
            _['sequence-item'], REQUEST)">
  </dtml-in>
  </dtml-if>
</dtml-with>

I'm assuming that the code within the <dtml-with ...> is effectively
opperating in the context of the newly created object, but when the
first manage_clone() is executed, it bombs out in _getCopy,
tripping over on this line:

ob=container._p_jar.importFile(f)

...because whatever container is, it's not a folderish object. 

So what do I need to do to switch to the new webDirectory object at
creation time, so adding methods is automatic?

Thanks,
John.

 Actually the limit is 4 GIG. however ext2 FS on Linux has a 2 gig limitation 
you can use a patch that will take it to 4 GIG, its available on the ext2 home

First of all, someone needs to let you know that data should never be 
stored in an Excel file. Anyway, what you would do is use the Zope ODBC 
database adapter. The Gadfly one is the only one installed by default, 
but others are availible at zope.org

You really should be storing that in a relational database though. 
Speaking for years of database experience, Excel is never a good place 
to keep things.

This isn't really a Zope issue. It's a bug in your script or the serveor

Ask those in the ODBC.Windows mailing list; this is not a Zope issue.

You might consider though, not using so many external methods and 
whether writing packages - they are more powerful and can be more 
powerful. External Methods are usually for quick one-timers.

I beleive you can do just that - return it as a list, and use it like 
this inside DTML

<dtml-in externalmethodid>

Hang in there. Learning to do this kind of thing in ZOPE is hard - I 
know because I'm trying to do it myself.

<dtml-var "search(name=name)"> should do the job, if I understand your 
question right. (Works like in Python.)

And remember: If you want performance, use any OS other than Windoze. Two 
good free DBs are PostGres (currently in 7.0 beta 3, yeah!) and MySQL. If 
you go to the RedHat site and sign up, they will send you Oracle 8i for 
free (or do they not do that anymore). I think Sybase has a similar 
promotion program. For all these DBs you have Zope DB Adapters.

Zope is cool, the docs are a big issue (I know), but a lot of people work 
very hard to change that. If you have suggestions of how to improve them, 
mail: Zope Documentation Project <zdp@zope.org>. Thanks.

Stephan

sorting is ascendingly by default (taken that you put a sort in the
dtml-tag, like 
<dtml-in sort=id>)

turning the sort to descending is done by putting in 'reverse', like so
<dtml-in sort=id reverse>

It is always ascending unless you specify "reverse" as an attribute with no 
argument in DTML-IN

<dtml-in "objectValues()" reverse sort="id">
   ...
</dtml-in>

Message-ID: <000601bf97c5$3590d960$0200a8c0@digitalview.com.hk>

Hi

I've got a load of files (PDFs, TIFs) that needs to be accessible from
within a Zope application. I need to be able to link to them so people can
download them. What is the best way to go about it?

If I add them into Zope (ie [Add new item]>[File]>[Browse]... etc is there
an easier way of doing it? I've got hundreds of files to add and I don't
want to do it using the HTML interface.

If I have the files in directory outside of Zope how do I reference them?
Bearing in mind I only need to link to them for download, no need for the
information in the files to be accessible by Zope.

thanks

By searching of the documents using ZCatalog, in query I list words with

with "OR" there is a word that is not in the index, ZCatalog finds nothing,
for example, "web or pop or mailvvv", but the documents with "web" and
"pop" exist. On www.zope.org the same effect. Is it possible to correct
this situation?

Subject: [Zope] zope search problems w/squishdot with latin1, locale fi_FI
Message-ID: <200003270923.MAA02125@katto.kaapeli.fi>

I'm using Zope 2.1.4 on Linux with environment LC_ALL set to fi_FI and
Zope started with -L fi_FI, and ZCatalog indexing & searching seems to
work fine.  (well, there's a problem with some documents having &auml;
etc. spelled out, but if ä is used everything works OK.)

BUT, ZDConfera & Squishdot don't work right.  For some reason, at some
phase of the indexing characters like ö (&ouml;, octal 366) in words
are converted to their octal codes.  This can be seen by looking at
the raw Data.fs file.  The result is that when I have a word like

kökköviesti

in the ZDConfera or Squishdot article, it can be found by search as

366viesti

It is converted in the db storing/indexing phase to something like
k\366kk\366viesti, which is then broken into words k, 366kk, 366viesti
which are stored into the textindex.

Any ideas on how to fix this?  I've looked at Splitter.c,
TextIndex.py, ZDiscussions.py and Squishdot.py, but I can't find
anything which would convert characters to their octal codes.

Aha! I have it!

Your external methods are given a pointer to self as the first
arguement.  You can use this to access any methods in the current
folder (self is the current folder)  So just call:

self.MyZSQLMethod(arg1, arg2)

where arg1 and arg2 are would be the arguments for the ZSQL Method.

Yes I am using postgres, however I am _not_ using the postgres adapter. 
I am using External Methods and python to do all data access since the data
requires formatting after it comes out of the database which is much
more easily done in python cf. dtml.

   Then you loose all the data caching done by the ZSQL methods.

Alas! It doesn't work.  It appears to fall down on the line:
  <dtml-let methodToCall="_[ methodName ]">

Traceback:
  File C:\PROGRA~1\Zope\lib\python\DocumentTemplate\DT_Let.py, 
      line 144, in render

      (Info: ((), {}, None))
TypeError: (see above)

It seems evaluating this doesn't just give the string contents of the
dictionary item, it evaluates the actual external method call.

I think I'll have to give up at this point and take the cludgy option
(unless anyone can think up another way).

Thanks for your help.

Yeah I know, which is a shame, however the postgres db adapter is only a
development version and as I said we need to manipulate the data in python
before it comes out of the db. I plan on putting in my own caching routines
here, however this will still only get me up to at most 8 request per second,
which is proably reasonable for my application.

Cheers,

Hello,
i'm testing Zope 2.1.6 with Windows NT 2000. Everything is running fine
but... it's
slow updating the internal database. Each time you press the "Change"
button the wait is 30 seconds! On the same machine with Windows98SE and
Linux there is no wait.
All the other operations are working without any problems of speed.

Is there anyone else who tried Zope with Nt2000?

Thanks,

Message-ID: <38DFE1F7.290CCF16@hal.varese.it>

Hello,
i'm a fan of statistics, i want to know how many hits my sites have
received, from which country, how long, etc. etc.
I run several programs to analyze the logs from Apache and Zope but, i
don't know how to split the log files of Zope for different sites.
In my situation i have some web based only on Apache, as virtual hosts
where i can specify which log file to use for that single entry; some
are on Zope, virtual hosts done using SiteAccess and ProxyPass. Mine
problem is that i want one single different file for every virtual host
i have on Zope.
Is there a solution?
I also have problems with kill -hup, it doesn't work with python, so to
take the daily log
i have to stop Zope, take out the log and then start it again. Ok, it's
not a big problem, but that single minute of pause it's not making me
happy!

Thanks,
    Bruno

Yes, I have been running it for a while on 2000 Pro and advanced server without

I'm running my dev-server (2.1.4) off my
win2k-box..(P2-400Mhz - win2k professional)
Usually, updating is close to instant, but occasionally i
experience 20-30 second hangs when updating.. Never thought
of it as a problem, though , as the machine is not a dedicated server
and i run a lot of stuff of it simultaneously (browsers,
photoshop,etc..)

This I cannot understand, what's new ;-)
I've mocked it up in the attached .zexp if anyone wants to try it out themselves.

I have a site with a subfolder. This is private and so has 'view' permission only to a 'user' role
and the usual 'manager' role.

I have a file, index_html in the mockup, in this subfolder, which includes an image called 'black'
from the root of the site. The root folder has 'view' granted to the anonymous user.

I added my users with the 'user' role, user1 in the mockup - password 'user1', to the subfolder's
acl_users . However, when I went to view the subfolder and logged in as user1, the page loaded fine,
except for the 'black' image. I was asked to authenticate again but the only way I could get past
this was to use user2, password 'user2', who has manage access to the whole site. 

This is really confusing as 'black' comes from the root of the site, which is viewable by even the
anonymous user, and viewing the black image on its own in another browser session, even using the
URL from the HTML generated for the subfolder index_html, worked fine and no authentication was
requested.

Obviously giving these users manager access to the whole site was unacceptable. I managed to solve
the problem, see user3 - password 'user3' in the mockup, by creating the user in the root acl_users
folder and giving them no roles. Then, giving them 'user' as a local role in subfolder.

I've tried this with Zope 2.1.4 and 2.1.6 on Linux and NT4, Netscape 3.04, Netscape 4.7 and Explorer
5.1 all with the same result.

Anyone know what's going on?

Chris

I had the same question, and found the answer in the code of the SQLSession
product.. I haven't tried coding it myself yet, but its does exactly what
you (and myself) are trying to do...

I have used <dtml-try> but it does not work.

Anyone have another way to handle this error?

If you want to use pythonish expressions in a dtml-var tag, just quote
them.

e.g., <dtml-var expr="myStr[:4]">  will get you the first four
characters of string myStr.  The 'expr=' part is optional.

Message-ID: <002d01bf97f7$73216d30$0980b1c3@net22.net>

Hi there,

I'm trying hard to make my Oracle8i  (Oracle 8.1.5.0.1)  for Linux  on
Redhat 6.0 with Python 1.52 plus python-devel installed from rpms and Zope
2.1.6 talk to each other...


As I understand so far, I first have to

Right?

I tried the new Oracle8i  setup-file provided on www.zope.org, I also tried
both Setup-Files provided with DCOracle, but everytime the same.

By the way, I suppose that there is no problem with the Oracle
client-library setup, because I am already connecting to the Oracle8i with
PHP.
I've never had problems with Python installed from rpms? Did anybody else
have?

some additional data points on those crashes:

in my test setup (CVS checkout using ZOracleDA) i found the following
ways to avoid crashing:

- using Pavlos' cure (setting DEBUG=1 in asyncore.py)

- manually closing the oracle database connection or deleting it (which
renders the membership components of my site useless since all that info
is in oracle)

- calling the offending page directly in a python interpreter by talking
to ZPublisher and circumventing ZServer

my suspicion is some weird interaction between the database adapter and
ZServer.

How can this be fixed?  

I can probably figure out how to make sure libpq (postgresql API
library) is reentrant (it might be already).  What has to happen to
the DA to make this work?

And if this was done, could you configure the DA to open, say 5
backend processes and use them in turn?

Thanks for your input.However I'm not sure that i really understand it. I
guessed that in that method the key element is popertyMap. So I tried:
<dtml-var propertyMap> in my zclass_addForm.

When i tried to add a myzclass instance anywhere in the ZODB hierearchy i get:
({'id': 'title', 'type': 'string'},)
Not exactly what i wanted. I wanted to get the ids and types of the
propertysheets properties.

Here is the purpose. I found that the default method of adding ZClass instance
is boring. The form asks you to type the id, then you can add your instance and
after that go to the propertysheets/myproperty/manage method to fill the
propertysheets properties.

I think that most of the times it's better to fill these properties when you
create the instance. So i began to modify each time, the addForm to include
the propertysheets properties in its form. It worked fine but each time i
create new ZClass i have to modify manually the addForm. So i tried to create a
generic addForm that could work with any kind of ZClass no matter what are the
propertysheets properties.

That's why i wanted to get the ids end types of the propertysheets properties of
a ZClass from outside the ZClass.

I can do that by creating an instance, taking the needed information from that
instance to generate automatically the addForm, creating a new instance with
the addForm then deleting the instance from where i got the required
information about the propertysheets. It works fine but it's not very elegant
and may a source of potentiel problems. Here is a "addForm" code that works:

<form action="ebook_add" method="post" enctype="multipart/form-data">

<table> 

<tr>

    <td><input type=text width=25 name=id></td>

Another possible solution would be to create a new instance with temporary id

Yellow,

I don't know about all you but I'm trying to use MySQLdb  0.1.2 on NT4 +
SP6a + Zope 2.1.4
The Installation Instructions aren't to precise on using it on win32
platforms and Zope doesn't show me the MySQLdb on the product list. Is there
some special steps to install it on NT?
I've seen the instructions page on zope.org and I know about having to aplly
the patch and compiling the .py on unix systems.. but what about win32?

anyone?

To use the propertysheet before you have an instance, you need to get the
Product into the namespace stack, something like this (untested, but I do stuff
like this elsewhere)::

  <dtml-with "manage_addProduct[ 'MyZClassProduct' ]">
   <dtml-in "MyZClass.propertysheets.info.propertyMap()">
    ....
   </dtml-in>
  </dtml-with>

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Hi,

I've Zope 2.1.4 running on NT4.0, using ZServer.
I would like to set up IE5.0's "Web Folder" feature
for Zope, with Zope's authentication. I could set
up a web folder, but it doesn't do authentication,
so I can't've any PUT rights...

Any thoughts?

Thanks

You should be running Zope with -D option and no -Z option, ie not as a
deamon. Then you will be able to see the connections that come in and out.
Seems though that there are two (or more) problems.

I don't think I'm following you - what do you mean 
by "it doesn't do authentication"? After setting up 
a Web Folder pointed to a folder in your Zope 
installation, what happens if you try to drag a file 
from your desktop to the Web Folder?

Has anybody seen this before? I seriously doubt my maxusers setting is
the problem -- this usually indicates an infinate openfile loop. Anyway,
the short of it is that Zope isn't starting. I'm using FreeBSD 3.4 and
Python 1.5.2.

Oops!

Sorry, folks. Stupid IE problem. I don't know
what happened, but went to MS site, downloaded
5.01 and did a complete re-install, and it is
working fine, now.

Another thing - would it be possible
to've https for ZServer webDAV? I'm trying
to push Zope's use in my organization, and
right now, am toying with the idea below
(because FTP is ruled out by our security
guy).
  - Run Zope as a webDav server
  - IE5.0 as client
  - People who want to post content to the HTTPD
    server (which is IIS3), just drag and drop
    from their PC to the Web Folder.
Issues as of now:
  - How to get the content to NT folders rather than ZODB?
      localFS does not permit uploads... May be I'll try ZMirror.

I work for a non-profit organization and right now we are
not in a position to adopt IIS5 or NT2000. Nor do people
want to go for Apache + Linux. And I could'nt find out
any other affordable webDAV server for NT.

Zope has got lof of people excited in my workplace and
that is also one reason I want to push for Zope.

Message-ID: <00032712571600.01015@modemcable215.47-200-24.mtl.mc.videotron.net>

In the Z Class tutorial (page8) I read:

"Property Sheets also allow more indirect access to properties via the
propertysheets attribute. ... we could access the 'title' property via
propertysheets.stuff.title attribute in addition to simply the title attribute.
The sort of access is handy in the case where two different propety sheets
define properties with the same name."

Sounds great, so I tried to use to it to create a sort of "international" class:

myClass:
    propertysheets
        english
            name
            description
            .....


but if i try:
myClass:
    propertysheets
        french
            name
            .....

i get the following werror message:
Invalid property id, first_name. It is in use.

So it seems that contrary to what suggests the Z Class tutorial it is not
possible to have two properties with the same name in the same ZClass even if
they are in different propertysheets at least when using the management tabs to
add a new property.

Is it a mistake in the tutorial or is there another means to add a property
with a same name in another propertysheet without getting an error?

I was just about to implement a similar method, and it occurred to me that I
would have to give a proxy role to the method so that it could add a user.
Have you tried that?

I do something very similar in the ZGotW product's root factory::

 <dtml-in "defaults.objectIds( 'DTML Method' )">
  <dtml-let si=sequence-item>
   <dtml-with newRoot>
     <dtml-call "manage_addDTMLMethod( si, '', defaults[ si ] )"> 
   </dtml-with>
  </dtml-let>
 </dtml-in>

The key here may be the inner '<dtml-with newRoot>', which is forcing the
newly-created root folder to the top of the namespace stack, so that
'manage_addDTMLMethod()' is being invoked on it, rather than on the
sequence-item.

Hope this helps!

Subject: [Zope] date property format
Message-ID: <20000327195040.3288.qmail@hotmail.com>

Hello you all!

I have a timestamp, for instance, 2000/03/27 19:57:53.9808 GMT.

Lets say I have a document property, type date, where I want to
store this timestamp.

I found that the use of A or B is different:

A)

	<dtml-call "REQUEST.set('Prop1', ZopeTime())">
	<dtml-call "manage_changeProperties(REQUEST)">

B)
	<dtml-call "REQUEST.set('Prop1', ZopeTime())">
	<form action=manage_changeProperties>
	<input type="text:date" name="mydate" value=<dtml-var Prop1>
	<input type=submit>
	</form>


The difference arise when formating for presentation:

A)
	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 18:57

B)

	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 19:57

Note: the 1 hour difference.

	I guess the difference is in the "Prop1:date" that forces
zope to create the correct object with all the information needed to,
for instance, recognize the GMT change since March 26.

	I found that using another kind of presentation format will
bypass this problem, i.e, instead of fmt="c style", I use functions like 
dd(), mm(), timeminutes().

	Is there a way to make the code A tell zope to create a
correct date object(property)?

My best regards,
Júlio Silva

Subject: [Zope] Creating Python class instances via DTML
Message-ID: <38DFC3D2.92037BD3@www.ifopen.com>

Greetings,

	I have created a Python class (Lead) and added it as a product and
am able to create and edit instances via the managment interface.
However,
I have run into a wall when trying to do so via DTML. Taking the path
used
in the "Adding ZClass Instances Programmatically" HOWTO, I've tried
things
like:

	<dtml-with "manage_addproduct(['Lead'])">
	<dtml-call "manage_addLeadForm">
	</dtml-with>

where "manage_addLeadForm = HTMLFile('leadAdd', globals())" appears
within
".../Products/Lead/Lead.py" and "leadAdd.dtml" contains the form used
to populate the object fields. I continually get "NameError's" on
"manage_addLeadForm" so I'm guessing that I'm have namespace issues.
Can anyone point me in the right direction?

				Thanks, Bill

Sounds like you want to roll the results into a ZRDB Results object,
like an sql query results object.

from Shared.DC.ZRDB.Results import Results

I'd suggest that you take a look at Shared.DC.ZRDB as well as Ty
Sarna's TinyTable Product which does this in a more simplistic
manner.

One of my product has a LocalFS descendent class, where I can upload
files. Well I simply use a Zope file object for uploading, then I save
the content of the file object into a NT folder. If it helps you I can
send this code for you.

Is there a way to do this using Zope-zserver, and not Zope-pcgi?
When I started this, I was just using the Zserver....but now that I need
to include calls to cgi programs for the sake of a couple images, I am
thinking I will needs Zope-pcgi..

If this is the case, I will need to uninstall the Zope-Zserver (if I try
to have both, there is a conflict) and install Zope-pcgi.  Does this mean 
I will have to import all the files, directories, etc. back into Zope, and
then reconfigure all of the files (replace all SSI lines with
dtml lines, etc)?


Thanks,

Made no difference here either.

In desperation, I moved the server behind an apache using fastcgi. Same
problem persists...random crashes with aaiiieee 11 and 256 in the debug
log, often with core dumps.

May be time to move away from the Lintel box (stock redhat 6.1, 2.16 src
install, pII350, 256mB ram) - I don't see this on a sun box I'm also
running.

Does this happen with binary installs ? Is it just redhat 6.1 (we didn't
see this on 5.2!)? One problem is that the zmonitor usually works - the
server restarts itself and users may only notice a long delay. I see it
because I'm watching the logs anxiously.

True, I still get the restart problem. What the DEBUG=1 solved was the
mysterious exits without core dumps or debug notices under very little 
load (I cannot still grok why it would kill the monitor process too).
Under high load we still get crashes but at least now when it dies the
monitor process will usually restart Zope.

We are also running behind FastCGI but as you have experienced too, we
still get the crashes, at least every 5-10 hours sometimes more
frequently. (And we have no DB connections or any weird code.)

About to give up ...

MySQLdb is the python client (driver) for MySQL.  ZMySQLDA is the Zope
Database Adaptor which interfaces with MySQLdb to access the MySQL database.
As far as getting it to run on NT,  good luck.  

Under Debian the whole process looked like this:
  apt-get install ZMySQLDA

I let some poor Debian developer worry about how to configure the two and
make it all work.

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Well, I just moved my zope to a Solaris box rebuilt with gcc.  I'm now
able to CONSISTENTLY get this thing to crash.

What i do is point a couple of wgets at the box to recursively snarf
up pages.  This doesn't seem to cause any  problems (yet)

Then with my browser, I try and load up some pages.  Usually, within
four or five attempts at loading pages, BAMM zope starts eating up CPU
cycles and within two minutes zope crashes...

And this is what the debugger tells me:

Program received signal SIGSEGV, Segmentation fault.

Yes, at one point, in desparation, my method had all the rights I could
grant it :)  It turned out that you have to give the rights to the
object you're cloning, too.

Hm - what we need is someone running on Solaris who can get
crashes, who also has access to purify. We're moving from
linux to Solaris at the moment, and I'll be getting hold of
purify to try and track down this damn problem.

Jon 

I did a search on the web and found out a few complains about programs
compiled with gcc seg faulting. One posting mentioned a faulty
implementaion of the pow() call, of course I have *no clue* how or why it
causes problems in Zope.

One more thing.
Can you try disabling multithreading by giving the option -t 1 to z2.py?

Good to be able to reproduce the problem. I suppose I can call it progress
...

Subject: [Zope] multipart content type
Message-ID: <38DFFDC2.AF2335FA@adroitnet.com.au>

Hi,

I need to get zope to server multiplart content.  The problem I have is
that Zope always puts its own header with a content-type,
content-length, etc on each RESPONSE.   Is there any way to stop zope
doing this?   This is a problem because the RESPONSE specifically needs
to look something like this:

        Content-type: multipart/mixed

--Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: application-compressed/zip

      {contents of .ZIP file, character for character}

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: text/html

      <html>
      <head>...</head>
      <body>...</body>
      </html>

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!--

I can set the content-type that zope returns by using
RESPONSE.setHeader, but i cannot control what else is put in the header,
and the order of the header attributes.  This causes a problem with
multipart messages because the boundary string needs to directly follow
the content-type: multipart/mixed, and the first message part
content-type needs to directly follow that.

Any suggestions?

Hmm... if you just want to check that everything is there, try
(untested):

<dtml-if "_.len(REQUEST.form) > X">
  render page
<dtml-else>
  go back and fix it
</dtml-if>

where x is the number of variables in your form.

Yes you can but it is more involved than the management interface. Can you
log in into the management screen of a different folder? Then you can undo
from there.

Yes and no :-) Your product's add method creates a folder object, then 
switches to it and adds the default methods with each appropriate add
method. What I was trying to do was add a ZClass based product with
the createInObjectManager method, then use manage_clone to copy my
default objects across. 

It turns out I was doing this from the right place (inside the
dtml-with that is used to create the object), but manage_clone is
broken - it let you copy objects into a thing you've just created
inside the same method at all. I'm pretty sure this is a bug - I'd be
interested to know if anyone has actually got this working at all.

In the process of testing this out, I discovered another piece of
unexpected behaviour - you can do this:

<dtml-with "manage_addFolder( rootID, rootTitle )">
</dtml-with>

...and you can then switch to using that object straight away, but if
you do this:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
</dtml-with>

...the object you've just created doesn't appear to exist as far as
the rest of your dtml method is concerned. 

So I've got something working, using the various object add methods,
but I need to make sure I have one for each type of object in my
default set, and I have a feeling that I'll need to recurse into
folders to add those and their contents. 

Thank,
John.

Just curious, but I am using a rewrite rule from apache (same things happens if
append the folder to the URL using site access) and the controls for the calendar
keep appending the root folder of the site. For instance, jobs.domain.com
correctly displays items from the /jobs folder in zope, but the calendar controls
keep appending jobs as I navigate the calendar like after a few times I get
jobs.domain.com/jobs/jobs/jobs/jobs/jobs/myCal.

Is there anyway around this?

Arg! I don't seem to be able to add anything other than DTML methods
and properties inside a Zclass creation. So it looks like I'm back to
doing it all by had. What a time saver...

Graham

please correct me if I'm mistaken - having read the How-To it seems that it
only allows you to get at the *contents* of the files. All I need is a
pointer, a reference, to the file so someone can download it.

Anyway I tried it with the following:

<dtml-var standard_html_header>
<h2><dtml-var title_or_id></h2>
<a href="<dtml-var "support['brochures']['brochure.pdf']">">Test Doc</a>
<dtml-var standard_html_footer>

When I view this in the browser I get a 'Save to file' dialog, I duly saved
the file (it was an HTML file) and on viewing the saved file I can see that
it does indeed
contain the contents of brochure.pdf(!), which is not what I want.

To re-phrase my original question - how do I construct a URL in Zope such
that it can refer to a file on the local filesystem?

thanks

The traceback is in error_tb -- try <dtml-var error_tb>

Other variables that are defined for error messages are:

  error_message (may be null)

Take a look at /standard_error_message for their usage.

Subject: [Zope] Serving external files
Message-ID: <38E068A5.11CCAA4D@rrsg.ee.uct.ac.za>

Hi,
I have some questions about serving external files:

I want to be able to serve a file that is external to Zope's Object
database. This file would probably be a binary file. So far, I have an
external method that reads the data from the file, and sets the header
of the RESPONSE object passed to it. The external method looks something
like:
    def readFile(self, REQUEST, RESPONSE):
        ...
        data = f.read()   # where f is the binary file, and has been
opened
       RESPONSE.setHeader("Content-Type", "application/data")
        return data

The zope id of the external method is "getFile".

I have a dtml method that calls this external method, using
<dtml-var "getFile(REQUEST, RESPONSE)">
The id of this dtml method is "download".
Say I have a dtm document with something like
<a href="download">SomeFile.dat</a>

This works, and the file is downloaded correctly. I want to know firstly
whether there is a better way of achieving this.
Secondly, when the user clicks on the SomeFile.dat hyperlink, and the
browser's "save as" dialog pops up, the browser uses the id of the dtml
method "download" as the filename in the dialog. Obviously I would
rather this dialog shows the name of the file that will be downloaded.
How can I change this? I can't rename the dtml method suitable for each
different filname that might be downloaded, so where else can I alter
this behaviour?

Thanks
Allen

Take three. I've solved the problem for all cases by having the ZClass 
add method redirect to a method that copies the default methods into
the new ZClass instance, then redirects back to the management screen.

Might have to write a howto for this one.

<dtml-var ***> with an image object writes out a full <img
src=***>-tag..
Your html-will look like this :
background"<img src="myimage">"

write it out as straight html :
background=myimage"

the error you're getting is probably because of the faulty
qouting in the dtml-var-tag..

Message-ID: <v04205507b5061c302dc9@[130.227.115.56]>

Hi,

I have a simple question - how do I use the fmod function in the math 
module with dtml ?

I've tried something like this(and a lot of variants):

<dtml-if expr="_.math.fmod(x,y) == 0">
	do something
</dtml-if>



What is it for:

I have some words returned from a search which I want to be displayed 
like this:

word_a	word_b	word_c
word_d	word_e	word_f
word_g	word_h	word_i

Thanks in advance.

And with good reason, you have overlapping angle brackets, your expression should read

<body background="<dtml-var "myimage">"

or

<body background="<dtml-var myimage>">

but this won't achieve what you want. What you really want is:

<body background="&dtml.url-myimage;"> 

See http://www.zope.org/Members/AlexR/EntitySyntax for more details.

Try looking at the LocalFS product available on the Zope.org site.

It makes folders on the physical drive look like part of the ZODB.

You need to recompile your kernel with an higher value for MAXUSER parameter
(x2 or x4 the current value).

MAXUSER parameter helps the kernel handle the load of the machine(max file
numbers, buffers, etc...). Python&Zope opens loads of files on the
filesystem, so the default value for MAXUSER is not enough.

Hope that helps.

Hi

The following snippet (tested) works as expected, printing the values in
three columns.

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('WordList', ['word_a', 'word_b', 'word_c', 'word_d',
'word_e', 'word_f', 'word_g'])">

<dtml-in WordList>
  <dtml-unless sequence-start>
    <dtml-if "_.math.fmod(_['sequence-index'], 3) == 0">
      <br>
    </dtml-if>
  </dtml-unless>
  <dtml-var sequence-item>
</dtml-in>
<dtml-var standard_html_footer>

Yes. Use the LocalFS product, it's taken care of a lot of the things 
that you're battling with (I've done the same thing and am in the 
process of moving to LocalFS).

Again, LocalFS will do this for you (my main reason for switching!).

Subject: [Zope] Is Zope suitable?
Message-ID: <000001bf989a$f08d97a0$1e01a8c0@tingeling>

Hello!

I have some questions about Zope and I thought I ask them before
spending alot of time reading the documentation.


Can I install zope on a apache system WITHOUT being root? My ISP is
running apache on a Solaris 5.6 system.

I want to create a system that lets any user create his own User Data
Record. The user data record will contain data about the user, e.g.
Name, email address, etc. This record should only be editable by the
user (and admin) with somekind of login. This user data must then be
searchable! Listings on all or some of the data should be able to
present in different sorting orders, e.g. Lastname, country, etc.

Is Zope suited for this kind of system?
Maybe someone already has created a system like this?

   You can, but would your ISP allow you to run Long Running Process? Zope
is LRP, you know, and many ISPs are very afarid of it.
   In any case you'd nned a support from ISP to setup a way their WWW
server will use to talk to your Zope installation - pcgi-wrapper,
mod_pcgi2, ProxyPass...

We made something like this with zclasses and regular user
folders recently, using a zclass to hold the
info, and dynamically creating users with localroles in
their own zclass-instance, allowing them to edit their own
information..

Not the best way if you expect a lot of writes to your
server,i guess,  but nice enough for small sites..

Thanks -
I have downloaded LocalFS, but haven't tried anything substantial with it,
my reason being that I needed to upload these external files as well.
A user must be able to upload a file, which will be saved to the local file
system, and made available for download from the local file system. The
actual path to the file will be stored in a relational database (along with
a whole lot of other info). If I were to use the LocalFS product for this,
is it possible to add a LocalFS object dynamically (through some dtml method
that gets called when a user uploads a file)? Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.

Any comments appreciated!
thanks
Allen

Thanks, this works perfectly. I don't know why my code doesn't work 
because I have tried the same thing as you have. But I must have

Yes, but just set up a LocalFS object from the management interface 
and don't worry about it. If you're worried about files cluttering up 
the filestore, use a cron job to wipe them out.

Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.


It uses python filesystem methods, so I reckon the number of files in 
a LocalFS object (ie the directory) is os limited.

I sent an email to the list on the 21st March where I had some 
(rudimentary) dtml and python code that uploads to a LocalFS object 
(ie the directory that the LocalFS object is pointing to). Check it 
out, the subject line is [Zope] Re: [Zope-dev] RE: ZDiscussions

Message-ID: <REhvNZAilI44Ew7q@compkarori.com>

I couldn't see this covered in the Zsql user's guide.

select myfield from foo

works as expected.

As the current ODBC driver I am using has a bug which truncates varchar
fields, it was suggested I cast it to char while retrieving the field.

But

select cast(my_varchar_field as char(140)) from foo

gives an error with the following traceback...

I just found a HOWTO by jpenny: Accessing a ZSQL method from an 
external method. It helps a bit but actually I don't want to use a 
ZSQL method I just want to take advantage of a persistant connection. 
Wait, I got an idea ...

[20 min. later]
Hooray! Try this: I have an open ZMySQL Database called 
'my_connection'. Now I can query the db from my external method with:

self.my_connection._v_database_connection.query('select * from whatever')

[another 20 min. later]
I benchmarked it agains opening a connection and cursor and then 
execute() and fetchall(). Using the Zope connection took about 60% of 
the time the other method took.

I wonder if there are any disadvantages???

Synchronicity!  I've just read the same document today and found the python
code for database connections (in ./lib/python/Shared/DC/ZRDB/Connection.py,
if anyone is interested :-), and am about to try passing my own queries in.

> I wonder if there are any disadvantages???

The only one I could immediately think of was "what if the database
connection hasn't been opened".  I can see the method for
manage_open_connection() (and _v_connected/connected() for the status
of the connection), but don't feel 100% comfortable calling Zope
internals just yet.  Any caveats for just semi-blindly calling
.manage_open_connection() if .connected() returns false?

Subject: [Zope] Problems with ZCatalog-indexing
Message-ID: <Pine.GSO.3.96.1000328140758.20415A-100000@nausikaa>

Hello all,

I've got some problems with indexing in ZCatalog.

First of all it doesn't seem possible to index words containing any
non-ascii characters (most important german umlauts). On zope.org the
only info on charactersets I found was, that there are some supported
ones, but I couldn't find out which these are.

How is it possible to have a correct indexed catalog on a german site ?

The second problem is related with the first one, but not restricted to
german characters.
Words where a hyphen appears, e.g. names like 'Hans-Dietrich', aren't
indexed at all, in the example 'Hans-Dietrich'
cannot be found on the site, but 'Hans' or 'Dietrich' cannot be found,
either.

If I cannot fix these Problems, the ZCatalog is unusable in the site, as
there are a lot of important keywords using umlauts or containig hyphens.

Thanks for your help,

Tobias Kiesling

You should use a recursive mathod.

Write one method recursiveMethod:

def recursiveMethod(obj):
     result = []
     if obj.parent != None:
          result = recursiveMethod(obj)
     if obj.meta_type=='KBItem':
          result.append(obj.Title)
     return result

Then call this method like:

def GetParentNames(self):
     recursiveMethod(self)


This code is untested, but should work.

Stephan

I'm glad you found a workaround.  Just offhand, did you try to just call that
additional method, before redirecting to it?  I have seen a couple of cases
where I refactored code like that into a new method and then things got simpler.

We're phasing out hosting in favor of DASH (Dedicated Application Server

Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT for
some reason, there's an HP box available. For more details, see:

Hi,

I'm in the process of cleaning up our production Zope server and I've found a folder which has one
file in it. I don't know who created either of them and I'm wondering if they're redundant.

I'd like to find out who created the both the folder and the file and, if possible, when it was last
created. How do I go about doing this?

Cheers for any help,

Subject: [Zope] Newbie question - product embedding
Message-ID: <38E0C7B5.38276033@advis.cz>

Hello,

I am just evaluating the Zope system, and it looks good. I am trying to
build an example Intranet site, using Squishdot.
I need a poll embedded in one of the Squishboxes.

I tried both PMPPoll product and Poll product, but cannot get it to
render into the page.

I have a DTML method calling the poll object like this


... some simple HTML ...
<br>
<dtml-var name="my_sample_poll">
<br>
.. some more simple HTML ...

The simple HTML indeed appears in the box, but instead of the poll form,
which I expect to be rendered, I get the following in the page source :

<br>
<Survey instance at 8635589>
<br>

Am I missing something obvious? Should I call the object from within my
DTML method some other way? Thanks for your help.

Hi,

Yes, this gives me parents, but it doesn't work for my problem :

The external method is used for storing the information into a ZCatalog.
Now, when the Catalog is updated, I get the wrong parents, I get the
parents of the catalog and not of the object itself. :-(

Somebody another idea?

Tom.

I tend to agree with Tres here. MySQL can certainly handle BLOBS, but
here's something you might not realize: All MySQL queries are literals.
Let that sink in for a moment. What does this mean? Suppose you are
using MySQLdb (not a ZSQLDA, we'll get to that). You need to do
something like this:

c = db.cursor()
c.execute("INSERT INTO BlobCity (Pix) VALUES (%s)", pix)

Looks simple, doesn't it? Well, here's what happens behind the scenes.
First MySQLdb has to turn pix into a MySQL literal value. Fortunately, if
you have, say, a JPEG class, you can write a function (not method) which
converts it into a MySQL literal. Suppose your class has a __str__ method
which returns the raw data as a Python string (maybe it IS a string
internally). Then you can do:

def JPEG2Literal(j): return "'%s'" % MySQLdb.escape_string(str(j))

(Although this is actually the default converter, used for strings; if you
have a __str__ method, you can just pass it to MySQLdb and it should do
the right thing.)

MySQLdb.escape string does all of necssary escaping of special characters,
namely backslash, NUL, and single-quote. But to do this, it has to
allocate a temporary buffer that's twice the size of the original string
to handle the pathological cases. Then quotes have to be added. Then this
all has to be inserted back into the original query. In the case of a 5 MB
BLOB, these steps work out to be:

1) str(j): 5MB
2) escape_string(#1): intermediate 10MB, return new 5MB+ string
3) "'%s'" % #2: return new 5MB+ string, but del #2
4) querystring % (#3): return new 5MB+ string, but del #3

So you're making and destroying a lot of big strings, which takes a
considerable amount of time. And we're only using one column and one row.
(I should probably make a new C function that combines #2 and #3 for
efficiency.) Most of what MySQLdb does is string crunching. For that
matter, MySQL returns all values to the C API as strings (including
numbers).

And now the Zope ZMySQLDA case: Z DA's always build literal queries
anyway, so this makes MySQL no worse off than any other database. (Most
database APIs, like ODBC, seem to use positional placeholders in the query
and pass the rows/columns as a data structure, which makes for much less
parsing on the server side, and is much easier to construct on the client
side.)

Compare this to writing into the filesystem. Well, no comparison, really.
open, write, done. So long as you can keep things organized, you're ok.

I'm guessing I could do it with MySQL...  what does everyone think?  
Is there a Zope plugin that already does this.  
Does someone have some code laying around you could send me?

MySQLdb is not a Zope Product; it's a Python module. ZMySQLDA is the Zope
Product. It needs to be patched to work with MySQLdb, however. I have no
idea how you would do this on Windows. Only the Python code (no C code)
needs to be patched. Stay tuned...

Message-ID: <3.0.6.32.20000328181014.0092e0c0@poirot>

Ok, now I found the error. The error must be in the while loop, where we
say 'iterate until the obj = None'. However 'None' is never reached... (I
guess). 
The following code works, but I this isn't at all a good solution. 

Can someone tell me how I can safely test that the current object is the
first object in the object database. In other laguages you can test this
with 'nil'. How can I test this within Zope? Please, tell me!

def GetParentNames(self):
  result=[]
  obj=self
  while obj.title != 'Zope':
    obj=obj.aq_parent
    if obj.meta_type=='KBItem':
      result.append(obj.Title)    
  return result

Thanks in advance,

Tom.

You must your locale environment variable correctly.  See 'man locale'
on linux, for example.  Also, you can pass z2.py the -L argument to
explicitly set a locale.  This will allow you to index german
characters.

Hyphens are hard coded in the text index to split words.  This is
because the text splitter is not very flexible and is very english
centric.

To fix this, you must either 1) create your own splitter, 2) update to
the latest CVS and create your own vocabulary and provide a new
splitter.  

The CVS version of Catalog is much more language neutral, and there are
now two kids of vocabulary object, English and Globbing-English.  Soon
someone I'm in contact with will be providing a Japanese vocabulary.  If
you have the patience, you should developer a German vocabulary to
address these issue.

Sometime between when your catalog was generated and when you tried to
re index the content you updated your CVS sandbox.  When you did this,
you got the new catalog code that doesn't work with old catalogs.

This non-backwards compatability has since been fixed.  If you update
your CVS to the most recent version this error should go away.

Let me know if it doesn't.

I think this would be a useful addition to the Zope core...I find
myself doing the same thing and I've been thinking about developing
the generic add form but haven't had time to even start it.

This works for me:

<dtml-with right_poll>
  <dtml-var index_html>
</dtml-with>

Of course you'll have to modify the poll's index_html document to
remove all of the full page stuff because you only want a table cell
for rightbox items.

Hi!

First of all I've to say that I'm a realy beginner in Zope.
I recently updated from 2.1.3 to 2.1.6 and noticed following problems:


In 2.1.3
<dtml-with "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
  <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
  </dtml-in>
</dtml-with>
 works great

In 2.1.6 it produces an Error message that
title, empf_sem, diplompruefungsfach is not known by the system
(I already Posted that)

Now I found out that
<dtml-call "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
 <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"_.getitem(REQUEST['fach'],1).propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
 </dtml-in>

works fine in 2.1.6. (getSubjectInfo is a SQL Method)

Has someone a hint for me?

Helmut.

Subject: [Zope] RE: ZCatalog Indexing
Message-ID: <38E0EC1E.7DBC7011@hiretechs.com>

Tobias,

The Catalgo uses a stripper to make the indexes smaller. It doesn't
index =-+*&)(^%$#@. etc... or numbers.  Some words too like 'Bill'. From
what I've been told there is a version of the Catalog on it's way which
will allow you to put keywords or charaters in a special place that will
include them.  I couldn't wait for that, and I love Zope, so I came up
with a major kludge.  catalog_quote() and catalog_unquote().  They are
from an External Method which I wrote catalog_quote.py.  Here it is:


from string import strip, split, join, uppercase, lowercase, find
bad_characters=(('.'),
                ('+'),
                ('-'),
                (';'),
                (':'),
                ('&'),
                ('*'),
                ('%'),
                ('#'),
                ('@'),
                ('$'),
                ('0'),
                ('1'),
                ('2'),
                ('3'),
                ('4'),
                ('5'),
                ('6'),
                ('7'),
                ('8'),
                ('9'))

def catalog_quote(self, ascii):
    text = str(ascii)
    for re in bad_characters:
        if find(text, re) >= 0: text=join(split(text,re),ordinalize(re))
    return text

def ordinalize(letter):
    number = ord(letter)
    number_string = str(number)
    myletters = lowercase[-5:] + uppercase[-10:]
    converted = ''
    for character in number_string:
        converted = converted + myletters[int(character)]
    return converted  + 'g'

def catalog_unquote(self, ascii):
    text = str(ascii)
    for un in bad_characters:
        if find(text, ordinalize(un)) >= 0:
text=join(split(text,ordinalize(un)),un)
    return text


I just use it to turn anything that might contain the charaters in
bad_charaters into catalogable stuff.

Then when you search, you must catalog_quote() your search strings, and
you'll get 100% accurate results.  Hope this helps.


All my best,

Message-ID: <3.0.5.32.20000329041128.009adc20@mail.skinnyhippo.com>

I had a ZClass (InnerClass) which was defined within
another ZClass (OuterClass) as follows :

/Control_Panel/Products/MyProduct/OuterClass/InnerClass

And a great many instances were defined with both
the OuterClass and the InnerClass. However, in order
to catalog the InnerClass (it is not CatalogAware 
and I do not want it to be), I need to move it to

/Control_Panel/Products/MyProduct/InnerClass

in order for 'InnerClass' to appear in the select
list ('Find objects of type') under the 'Find items
to ZCatalog' tab of the ZCatalog.

So far, so good. I moved the class and now can 
catalog it. However, now the icon is broken on all
of the instances of the 'InnerClass' ZClass. I 
have tried adding a new icon under the 'basic'
tab of the ZClass definition, but that doesn't
help either. I know it's just a petty icon and
it doesn't affect functionality but I'd really
like to clean this up so any clues/help appreciated.

Thank you very much,

chas

Hi all,

This code results in a error:

<dtml-let MyVar="_.string.replace(Mytext,'"','&quot;')">

I know its because of the quote in '"' because that cause in
same way an error when the "dtml parser" is parsing the code.

I've tryed to use '\"' and even _.chr(34) instead of " but the former gives 
me the same error and the latter dont give a error but also
dont do the string replace I want to do.

Any help?
Thanx,
Julio

This one goes especialy to ho write zope.

I have found that the dtml-in has a problem when you specify a batch-size that is less than the double of the length of the input list.
Ex.:
a list of 6 itens:
when size is 3, dtml-in returns 3 itens, correct. (3*2 <= 6) = true
when size is 4, dtml-in returns 6 itens, error. (4*2 <= 6) = false

Is this a bug?

Adding an "orphan=0" tag inside the dtml-in should do it:

  <dtml-in foo orphan=0>
    . . . bar . . .
  </dtml-in>

A more general question for the list, though:  Shouldn't the default
orphan value be zero?  It seems to me that if someone explicitly says
"I want three items," it should be more of a special case that they'd
somehow want more . . .

Opps. It works, but my sugestion of using _.chr(34) also works.
I was looking at the wrong results when testing _.chr().

Tried that - I in-lined it on the list for brevity's sake. The problem
is definitely with manage_clone not wanting to be used on a thing
inside the transaction that creates that thing.

Message-ID: <71D21CF19DE2D011AD43006097BD8C019D5C7B@SJMR-MSG-01>

Sometimes when I reference other dtml documents I get the dtml code returned
as text,  rather that outputting HTML like it should.  For example,  the
code I have below will print out the standard header properly and then
display the raw html where the Eligibility.MemberInfo document should be.
What am I doing wrong?

<dtml-var standard_html_header>
<dtml-in SQL_ViewMember>
 <dtml-var "Eligibility.MemberInfo">
</dtml-in>
<dtml-var standard_html_footer>

Hi there,
This must be simple, but I haven't found it in the docs.
Can I get ZopeTime to give me the date, say, 20 days ago ?
Or a month ago ?
Something like (yes I know this won't work) 
<dtml-var expr="ZopeTime - 20")

One thing you need to keep in mind is that dtml-in has an orphan
attribute that determines the minimum amount of items to print out.  If
orphan is set to 3 (default) and you have a list of 6 items, and you set
size=4, the dtml-in tag will realize that 2 is too little to have on one
page and so it displays all 6.

If you don't want this, set orphan=0 in the dtml-in.

Subject: [Zope] BASE tag on File objects
Message-ID: <m38zz23a9e.fsf@wacko.pdx.net>

I've got a number of static HTML files on my site that Zope keeps
putting BASE tags into.  IMHO, it is inadvertantly appending a slash
onto the end of the HREF.  For example a file called default.htm in
the classified directory ends up with a base tag of:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm/">

I would think this should be:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm">

So I have modified: OFS.Image.File.index_html to strip the trailing
slash by adding:
        # clean up the base if neccessary
        if( RESPONSE.base[-1:] == '/' ):
            RESPONSE.base = RESPONSE.base[:-1]

What think you?

-Jon

This should work:

<dtml-in SQL_ViewMember>
  <dtml-with Eligibility>
    <dtml-var MemberInfo>
  </dtml-with>
</dtml-in>

There could be a way with zserver but I don't know it. My advice is to
use PCGI for performance and salability anyway, though. ZServer is
quicker to setup, but in a production environment, apache is still
higher performance.

Although, having CGI scripts are never good for performance. ;) PCGI
is fine though.

You can generally have both pcgi and zserver installed without a
conflict; there's just no point to it. There very well could be a way
to "wrap" CGI scripts in zserver, but it would still be better done
in a true apache environment, where it belongs. To be 100% ZOPE you
would re-implement everything in Zope/Python/DTML though. I've seen
a lot of company areas where zope stuff points to CGI stuff and visa
versa, so your situation seems to frequently be solved that way.

You only need Zope-pcgi if the cgi calls need to come off of the
same IP as the rest of your zope.  If your Zope site is, say,
www.mysite.com, then you could put your image cgi stuff into an
Apahce responding to the an IP under the name of, say, images.mysite.com.
This would be your maximum performance route: direct calls to
Zserver for the Zope stuff, and direct calls to Apache for the cgi
images.

You only need the separate IP, by the way, if both need to be listening
on port 80 (say because people from behind a firewall need to access
your site).  If you can deal with either one listening on another
port, then Zope at least can deal with that (I imagine Apache can too,
but I've never tried it.)

> If this is the case, I will need to uninstall the Zope-Zserver (if I try
> to have both, there is a conflict) and install Zope-pcgi.  Does this mean 

What have you run into that makes you think there is a conflict?
When you run Zope using pcgi, you are still running Zserver.  It's
just listening to pcgi calls instead of port 80 (or whatever) calls.
It is certainly possible to run Zserver such that it will respond
both to direct calls and to pcgi calls.  This is the way it is set
up by default, at least under Unix if you compile Zope using
w_pcgi: Zserver listens on port 8080 for http traffic, and also
communicates with Apache using pcgi.

Reinstalling to add pcgi support is like upgrading to a new version
of Zope: copy your var directory (actually just Data.fs should be
enough) to a safe place, do the install, and then copy your saved
var overtop of the new one built by the install.  You'll also need
to reinstall any Products that you downloaded and installed.

Hi,

I am looking for a translation engine (similar to Babelfish) that can 
be fully integrated with Zope. The only option I found so far is 
GPLTrans, which is based on PHP. Before I start porting it to Zope: 
is there anyone else out there already working on a similar project?

Anyone interested in helping out with such a project? Have a look at

   http://babelfish.altavista.com/
   http://gpltrans.sourceforge.net/

to see what I am talking about. Results to be released under the GPL.

Thnx,
Jonathan

Hi,
How do I import a module - I've been reading the DTML guide, and I would
like to use some of the functions described in the string module, but
how do use them - do I have to import the module (if so, how), or what
else. What I want to use is the following:
<dtml-if expr="lower(somestring)=='supplier'">

</dtml-if>
where lower is defined in the string module. I've also tried
string.lower(...) but that didn't seem to work.

thanks

I don't think you'd need any Zope products or additional code for a basic
implementation of what you want to do.

Just create the folder structure you want to have in Zope. Then you can add all
your documents with the management interface. To create the directory view, you
only need an index_html DTML Document that lists the folder structure (either
using the tree-tag or some dtml-in construction). 

For higher performance, you can use the ZCatalog to index the folder structure
and use code similar to the one on Zope.org to list the topic pages (e.g. all
the news on the Zope.org news page and all the products in the download area
are collected from the site using the ZCatalog.

I wouldn' use MySQL for that particular task because it fits the ZODB (Zope
object Database) perfectly (many reads, few writes).

You could also look into some of the products on the download page. I recall
that there might be some "out-of-the-box" directory solutions.

I'm finding myself again trying to figure out how things work in Zope, just
to find out at the end that it is MUCH simpler that I thought  -- but totally
undocumented! Or maybe I just haven't looked for it enough ...

Isn't there somewhere a list of all method calls I can use from DTML (like
manage_addXYZ)? It can't all be just trial and error or "read the code". -- Yes
it can, but I don't want to be that pessimistic ;-)

O.k., my current problem is that I have a folder with icons and images in a
ZClass that should be copied to all new instances of the class.

There seems to be a "manage_clone" call for that (just read about it in a
posting), but how does it work and where do I find any documentation on it?

As all those methods are in the namespace, isn't there at least a trick to get
a list of all names to print out? That would be a first start.

I mean, I had to figure out every single call like manage_addDTMLDocument or
manage_changeProperties by trial and error. That makes Zope so much less
efficient that it could be ...

The string module is already available, just not as you'd expect ;)

Try something like:

<dtml-if expr="_.string.lower(somestring)=='supplier'">

</dtml-if>

You could also try <dtml-var "Eligibility.MemberInfo()"> although this might to use the namespace

from the zqr: 

manage_clone(ob, id, [REQUEST])
           Clone an object, creating a new object with the given id.

have you tried :

<dtml-var "Eligibility.MemberInfo(_.None,_)">

- just might do what you want..

Don't ask me about the specifics of what  (_.None,_) does,
though.

Subject: [Zope] passing arguments from dtml methods to SQL methods
Message-ID: <38E1D121.D5689279@rrsg.ee.uct.ac.za>

Hi,
Thanks for previous help on the namespace variable '_', much
appreciated!

I have another problem though, how does one pass parameters between DTML
methods, and from dtml methods to ZSQL methods?

I have a DTML method "getSearchResults" that gets called when a form is
posted using
<FORM... action="getSearchResults">
<INPUT NAME="fname"
</FORM>
The method gets called and magically the form fields like fname
described in the above form are accessible from the dtml method, so I
can do <dtml-var fname> and there's the input from the user. (I still
don't fully understand how that bit of black magic works...)

Ok, then I have a ZSQL method with fname as an argument, and again, when
my dtml method calls the zsql method, that variable fname can be
accessed using <dtml-var fname> in the SQL query. While maybe I don't
completely understand what's happening, I can still use it. The problem
now is, my ZSQL method needs to have an argument "tablename" that it can
use so that a different table can be selected, however, this tablename
is not under the user's direct control. It gets set according to some
choices that the user makes along the way. I would hence need to
"declare" it in the dtml method "getSearchResults", initialise it, and
pass it to the ZSQL method so that the ZSQL method can use it. I tried
doing the following: (suppose the ZMYSQL method's id is "searchMySQL").
in the dtml method:
    <dtml-if expr="whatever">
       <dtml-var name="getSearchResults(fname=fname,
tablename='suppname')">
    </dtml-if>
So that didn't work, but maybe it describes what I'm trying to do - that
is, fname exists and is initialised from the user's form input, but
I want to create the variable tablename, and pass it to another method
(or just create in the namespace space so that it's accessible to other
methods).

Sorry to be so long-winded, trying my best to describe things with my
very limited knowledge of zope/python.

Many thanks
Allen

Hm, is it - if it's undefined? 

what about (taking the function from one of your previouw posts) (only
lightly tested):

def recursiveMethod(self, obj, result):
    try:
     if obj.aq_parent:
           result.append(obj.title)
           recursiveMethod(self, obj.aq_parent, result)
    except AttributeError:
        pass
    return result

This is less elegant than testing for the attribute aq_parent, but
either hasattr is not allowed for External Methods, or ac_parent is not
an attribute.

Note, however, that if an object has no title it may also throw in an
AttributeError, thus aborting your method in too early. You could try
and catch this exception separately, but perhaps it shouldn't happen
anyway.

One small addition: I threw out the test for KBItem (because my Zope has
no such items), you can put them back in at line 4. Sorry for posting

Try using a COUNT in your SQL select formula. 

e.g.

Select count(colname) from tablename where colname='myvalue';

If it returns a 0 then that value doesn't exist.
If it returns anything then that is the number of times the value exists.

How about

<dtml-in "sqlFindItem(item=itemid)">
  <dtml-if sequence-start>
     do insert
  </dtml-if sequence-start>
<dtml-else>
     do update

Is it possible for zope to separate control from data automatically?

To make the best use of Zope, it will be necessary to separate the data and
control.

with XML, DOM will assign id for each node and thus  all of them can be
refered by that id.

Is it possible for zope to perform this? Will a modify of  load_site able to
do this semi-automatically? (run load_site over an existing zope tree?)

Message-ID: <Pine.LNX.4.10.10003291331390.19425-100000@oeh.tu-graz.ac.at>

if you want to pass variables to a dtml method you have the option to
set it in the REQUEST object eg.

  <dtml-call "REQUEST.set('varname', 'somestringval')">

or put it in the namespace eg.

  <dtml-let varname="'somestringval'">

then call your method as per normal eg. <dtml-var yourmethod> which
then will find the vars you set before.

or you call your method with keyword args like

  <dtml-var "yourmethod(_.None, _, varname='somestringval')">


note the difference between 

  <dtml-var "method"> which is <dtml-var expr="method">

and 

  <dtml-var method> which is <dtml-var name="method">


see the "Document Template Markup Language Reference",
http://www.zope.org/Documentation/Guides/DTML and the zope howto's.

Salutations,

I've been staring at this one for a while, but I can't quite seem to
pull it off.

I'd like to render a document based on the contents of a variable.
For example (simplified):

<dtml-call "REQUEST.set('foo', 'index_html')">
<dtml-var foo>

should (would? could?  I'd like!) render index_html.  Double
quotes don't cut it (both print the string 'index_html') :-(

- Because PrincipiaSearchSource (which is probably what you
are using for your full text search) is a property(method?) of DTML document and
method, but not of your new product..

try making a pythonmethod or external method (pythonmethod
is simpler) inside your
Zclass containing something like :

   return string.join((self.yourAttribute1, self.yourAttribute2, self.yourAttribute3), '; ')


where yourAttributeX are the attributes of your Zclass..add
as many you like...

name it PrincipiaSearchSource if that's what you're using
for the full text search.. (might be 'raw' too...)

Hi,
Thanks again for the help with the let and with tags...

I am making slow progress, but now can't seem to display my results from
a ZSQL method. How are the results returned? If they are in some
RESPONSE object, how would I read the items out?
So far, I have an SQL query which I'm fairly sure is working, and whcih
when tested gives the results I expect, but when I use it in the
following bit of DTML, nothing is rendered at all:

<dtml-call "REQUEST.set('cmatch', 'sup_name')">
<dtml-var searchMySQL>

The <dtml-var searchMySQL> line returns nothing, even though I know that
there are results for that method.

Apologies if I'm missing something I should be picking up from searching
the archives, but at the moment our connection is bogged down with lunch
time traffic, so I can't even get to the zope site.
thanks
Allen

No biggy..

<dtml-in searchMySql start=query_start>

<dtml-var variable_name>

</dtml-in>

That should get  you started but you should read the ZSQL Guide as it 
has lots of options that you can include (size, orphan, start 
sequence, end sequence, etc)

Really is worth the read.

Bear in mind you may have two pythons running on your machine.. the 'normal'
python that appears when you type 'python' at the command line, as well as
the python that zope installs. It may be that PIL is only in the path of the
former and not the latter.

In my case, 'foo' must be a string, and is actually passed in via
a POST (I need it to maintain state in a "wizard" style form).

Subject: [Zope] ZRDB
Message-ID: <38E22874.727DD231@wildenhain.de>

Hi,

browsing thru Shared.DC.ZRDB.Results i found this construct:

-------- line 117 ------------
		if not name:
			raise ValueError, 'Empty column name, %s' % name

------------------------------

This looks a bit silly, because if name is empty, %s will be replaced
with
nothing...
Furthermore, would it not be better to provide a generic name for the
empty column? Sure, it is difficult to provide such a name who does not
collide with others in namespace, but it would be very helpful, if the
underlying database-adaptor does not provide full names under certain
circumstances, such as ODBC with CenturaSQLBase always returns
empty column names to Zope with the count() Operator. Even if used "as"
to rename.
How about something like:
		if not name:
			name='column%d' % i

or such?
Next there is always some hassle with those 'table.column' columns
returning from databases who do not support column renaming.

Would it be a way to rename them automatically to something like
table_column? Yes, I know there could be a column already beeing 
called so. But if one knows she can use table.table_column in such
circumstances.
May be as alias?

I'm coming in late on this thread, so ignore me if this 
has already been covered... :)

It sounds like what you want is something like the following:

# docname is the variable passed in via the POST whose
# value is the name of the document to render. We use
# _.getattr(this(), docname) to retrieve the needed 
# document from the current object. Note that we use
# the "let" tag instead of REQUEST.set, which is 
# increasingly considered evil :)

<dtml-let theDoc="_.getattr(this(), docname)">
  <dtml-var theDoc>
</dtml-let>

Subject: [Zope] Problem with SQL+Special chars...
Message-ID: <B507F9A6.5E85%owrede@khm.de>

I am having a problem with HTML entities.

I am using Zope to enter and output text into a MySQL Database.

When I output the text, it is rendered through my own External Method:

   <dtml-var "myMthod(myText)">

I tired to write a little subrouting which is supposed to translate special
chars in the database into HTML during output.

Unfortuneatly the texts are entered on both MacOS and Windows browsers. This
unfortunatly makes it difficult: There is no unique ASCII code in the
database -- in other words: the same special char may be represented in the
database with to character values.

First I looked if the <dtml-sqlvar ...> had anything to offer, but that does
not seem to be the case.

How can I store text in ISO-Latin into the database regardless the Text is
entered via a Mac-Browser or a Windows-Browser?

Message-ID: <38E22FB4.7C8FFF18@nipltd.com>

Can you do colour in structured text?

The reason I ask is that I've just found out how great ZWiki Webs are but I'm wondering if there's a
shorter way of changing text colour than:
<FONT COLOR="#xxxxxx"> </FONT>

I'm looking to use a Wiki so a group of people can edit a web of documents and I was hoping that
each person could use a different colour. Having to do the colour by hand defeats the simplicity of
a Wiki :(

Any ideas?

Subject: [Zope] Mac2ISO conversion?
Message-ID: <B507FECC.5E86%owrede@khm.de>

I need to enter text data into a MySQL database via HTML forms.

Text entered on a Macintosh client is not ISO-Latin as it seems. When
getting that text out of the database, the special characters are broken in
the HTML page but not in the textarea.

Text entered via a Windows browser are not broken in the Mac browsers HTML
page - but in the textarea.

So I guess I should care for getting ISO-Latin text from the Mac clients
into the database!

From other areas I know this requires a mac-to-iso translation (in both
directions (because the text must be editable on Macs).


But how can I do this in Zope?

I know how to figure out, if it's a Mac-Client -- do I have to create an
External method fr this?

Hi,

I'm doing a back link to go on a page (yes, I know browsers have back buttons, but some people don't
like to use them ;-) which is easy enough:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>

except that if there is no referer, you get a key error. So I thought I'd try the following:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>">Back</A>

But I still get a key error. I thought the 'missing' attribute was supposed to catch that?

   Not quite. You are tripping a key error here so that won't work. Try:

<dtml-if "REQUEST.has_key('HTTP_REFERER')">
   <dtml-var "REQUEST['HTTP_REFERER']">
</dtml-if>

It still exists, in a very domant stage.  The next Zope release will
probably break it right out.  There's not much you can do with ZTables

Subject: [Zope] building/exporting site and server question
Message-ID: <4.2.2.20000329111442.00a63b10@mail.bowmansystems.com>

I am relatively new to Zope, and I am working on a personal project at home 
on my Win98 box. I am just now getting the "zen" of Zope as everyone refers 
to it, and am building a true functional application.

So now that I am getting comfortable with Zope, here is my question. I am 
wondering if I can build my site/application on my Win98 box at home, 
export it out and then import it into another Zope installation running on 
another operating system (either BSDI or Linux). I am thinking I will have 
to buy my own server so that I can let Zope run as the server itself -- our 
servers up here all run Apache and I doubt our systems administrator up 
here would want to take the time and effort required to get that running 
properly (plus those are production servers, not really for employee 
projects!).

Is it possible and/or recommended to build a site/application on one 
installation and import it into another? Or should I just go ahead and by a 
box, put Linux on it, and proceed to build it on that platform? My concern 
is spending a lot of time building out the site on my home box and then 
finding a show-stopping hitch in the migration to another 
platform/installation.

Anyone who has had any experience with migrating Zope applications to other 
platforms/installation please reply so that I can make an informed decision 
as to how to proceed.

And also is there any reason to use Apache instead of letting Zope run as 
the server itself -- this will be on my own server so I doubt there will be 
much else on the box then my personal project and my home site (two virtual 
domains).

Thanks in advance.

This counts only for something like <dtml-var ought_to_be_missing
missing>
In your case you are inside Python when calling with " ".
So "missing" cannot catch this exception.
(Actually this simple <dtml-var .. > does much magic :)
So in your case you should do:

<dtml-if "REQUEST.environ.has_key('HTTP_REFERER')">
	<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>
</dtml-if>

This has the advantage of no blind link if there is no HTTP_REFERER set.

The reasons I came across were if you wanted to use SSL or have a site that
is half Zope, half Apache. Otherwise for simplicity sake ZServer by itself
is a great option. It is certainly the fastest and easiest to set up.

I decided to swith the roles, as I have ZServer running on Port 80 and
Apache on 8080 to sever up statistics, documentation docs and other very
static and non-production things that would be difficult to get into Zope.

As for the W98 migration, I would say develop it on the box you are going to
use it on. In the long run all the experience you get on the development
will not transfer to another OS. Linux is a great way go.

Btw. this works:

<dtml-with REQUEST>
  <dtml-with environ>
    <dtml-var HTTP_REFERER missing>
  </dtml-with>
</dtml-with>

or 

<dtml-with "REQUEST.environ">
    <dtml-var HTTP_REFERER missing>
</dtml-with>

if you want :-)

If you are experimenting with WIN 2000 try creating a NETWORK MAPPING
(WEBDAV) to a ZOPE FOLDER.

1. Click on Network
2. Click on Add a Network Place
3. Enter the url to a ZOPE Folder
4. Done

You now should have a folder view in Windows that Maps to a Zope Folder.
Enabling all sorts of great things:

1. Editing and Saving back to the folder with Security
2. Drag and Drop assets into the folder with Security

Great work on the Implementation of WEBDAV!!! Thanks DC!!!

That's very good news! Unfortunately I haven't been able to 
install win2K yet to see how it worked - I know about one 
further tweak that a little microsoft birdie told me I could
use to enable editing of "unprocessed" source (i.e. double 
click on a DTML method from a web folder and have it open 
unrendered in your chosen text editor or something). It 
shouldn't be hard to add, I just need to get the time and find
a box that I care little enough about to put w2K on it... :)

They do not offer "normal" PHP as an option -- you could ask them if they would
quote it as a "custom" add-on.  With enough work, it might be possible to call
PHP through a Zope product;  I don't know enough about what support PHP requires
from the OS and environment to know if this is feasible.

Of course, I also can't think of any reason to use PHP, but that is another
issue altogether. :)

The render-method collects items from a catalog and calls these objects'
"render" method.
Unfortunately this raises an Unauthorised Error, whenever I do not use the
super-user account.
(Zope has encountered an error while publishing this resource. 

Unauthorized

You are not authorized to access render.

Ok, so I gave the calling Method the proxy-role of the Manager. No change.
The strange thing about it is, and that is what puzzles me, that it works
for another class (which does only slightly different things).

So, what now, hu?

Regards, Ingo.

Do you mean site usage statistics (page views, etc.)?

If so, how do you measure Zope's stats if it is running as a separate
server and logging separately?

ZServer runs at Port 80 and logs all of its activity to Z2.log. I have
Apache running on port 8080 and it is logging to its own access log. I run
Analog (and Webalizer) on the Z2.log (cron) and write it to the Apache HTML
directory. That way I can browse all the Zope stats I want while not having
to import the static HTML into Zope. This also works great for documentation
and other things that come as static HTML.

The site, though, is pure Zserver.

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the zope-announce mailing list and
    the Zope.org site.

    The ZWN is changing days!  The next ZWN will be published on
    Tuesday.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * ZEO will go Open Source

    ZEO, the commercial Zope scalability option from Digital
    Creations, will go Open Source. After a trial period in mid-April,
    it will be available to everyone by mid-May.

    ZEO (Zope Enterprise Option) turns Zope into a distributed
    transactional object system, allowing people to add processors,
    machines, and networks to scale their web applications.

    More information can be found on the ZEO Product page.

    http://www.zope.org/Products/ZEO/

  * Oracle 8i Setup file, by Chris Petrilli

    Chris has released his Oracle setup file.  This file is used to
    create the Oracle library.  It has been tested internally for a
    couple of weeks.  See Chris's announcement for a caveat.

    http://www.zope.org/Members/petrilli/Oracle8i

  * Zope LATEX Math, by Bruno Vernier

    On his site, Bruno describes how to use LaTeX notation to render
    mathematical expressions directly from Zope.

    http://ess.vancouver.bc.ca/zope/math

  * Users Group - Ohio

    James Orbin <jorbin33@hotmail.com> would like to set up (or would
    like to participate in) a Zope users group for Ohio.  If you are
    interested, please write James, or see:

New Products

  * Software Product: L10NFolder, by "fog"

    The author writes, "This is a subclass of the standard folder with
    some added bonuses. The L10NFolder support localized properties
    and search paths."

    http://www.zope.org/Members/fog/l10nfolder


Updates

  * Software Product: XML Document, by Amos Latteier

    XML Document has been updated to work with Zope 2.1.6.  The latest
    release is 1.0a6.

    http://www.zope.org/Products/XMLDocument

  * Software Product: Zope MySQL Database Adapter, by "mordred"

    "mordred" has released an update to the MySQL Database Adapter, by
    Michel Pelletier (Portland). This release is 1.1.4, and fixes one
    bug:

      - Fixed a bug that caused Zope to fail on selecting aggregate
      functions such as 'select max(number) from table'

  * Software Product: ZWiki, by "simon"

    ZWiki is a Wiki web for Zope.  Zope and Wiki are a good
    combination.  Wiki assumes that, in general, users are
    trustworthy.  Zope, with it's security and transaction history,
    makes it easy to trust users.

    ZWiki is a sort of anarchic collaborative authoring system.  This
    version, 0.5, streamlines the default pages and UI, and disables
    the experimental catalog support. This release is intended to be
    immediately usable out of the box.

Zope.org items

  * How-To: Changing Base Classes for a ZClass, by "AlexR"

    When you create a ZClass, you are given an opportunity to chose
    which classes it will inherit from.  Since ZClasses are often used
    for rapid prototyping, you will not always select the correct
    classes the first time.  It is quite a lot of work to create a new
    set of classes with the correct bases and to move all the contents
    into them from the old classes.  Armed with this How-To, you will
    be able to change the base classes of a ZClass in-place!

    http://www.zope.org/Members/AlexR/ChangingBaseClasses

  * How-To: Serve PHP/Perl within Zope, by "Mamey"

    "As you migrate your site to Zope, you may want to embed a
    previously created PHP or Perl directory tree within Zope. Or
    perhaps you found a nifty web application that is coded in
    PHP/Perl and want to serve it within your Zope site."  This is a
    bit more advanced than simply rewriting certain URLs to be served
    by a different server.  This How-To will actually allow you to
    embed the external content in dynamic Zope pages.

Thanks so much everyone for all the help...actually, I ended up still
being able to use Zserver (without pcgi)...I left  the cgi programs on my
separate non-Zope site...and then for the image source, I just used a link
to the site, with all the corresponding parameters to generate the
picture...like so:

<img src="http://www.mynonzopesite.com/cgiprogram?parameters">

This worked! So, I was able to keep the regular Zserver, and still do
calls (at least for an image generation) to a cgi program residing on a
completely different site...looks like I will stick with Zope now, since I
am able to do this. :-)

> What have you run into that makes you think there is a conflict?

When I would do "rpm -Uvh Zope-pcgi-2.1.4-1.i386.rpm"

I would get the following message:

"error: failed dependencies:
        Zope-zserver conflicts with Zope-pcgi-2.1.4-1
        Zope-pcgi conflicts with Zope-zserver-2.1.2-3"   

But I no longer need pcgi, so I guess this isn't a problem for me anymore.

Thanks Again,
Jessica

Nope ...

I installed Zope-2.1.4-linux2-x86 and worldpilot-release-1.0.4.tar from
the zope-topdir. It installs correctly in ~/lib/python/Products/WorldPilot,
but when restarting the server, there is no "WorldPilot" or something
similar in "Available Objects" ...

I did:

umask 000
mkdir /var/spool/worldpilot
mkdir /var/spool/worldpilot/storage
mkdir /var/spool/worldpilot/storage/user
mkdir /var/spool/worldpilot/sessions
mkdir /var/spool/worldpilot/user
chmod -R 700 /var/spool/worldpilot

I set "DOMAIN.py" to domain="math.uni-bonn.de"

I converted those ^M (meaning

not show up in the available objects	;-(

Still, those DOS-format may be part of the problem?!?!

Confused ...

User-defined role authenticationAdam,

Something before I answer your question.

Please don't send HTML formatted mail to mailing lists.

Not all members use clients capable of reading it correctly, it makes it v
difficult to decipher when using elm for example.

OK that said onto the question.

You need to create users that have that role and then set permissions
appropriately for the location in question.

For example try turning view permissions off for the location. then try
browsing to it.

I have defined a role, editor, in my Zope system. It is not clear to me how
to prompt a user who is not a manager to authenticate so that Zope will
recognize the user as something other than anonymous. Any pointers?

Help very desperate....


We have a Zope site running: 
	Zope version: Zope 2.0.1 (source release, python 1.5.1, linux2)
		(also happens on a seperate box running Zope 2.1.6) 
     	Python version: 1.5.2 (#6, Sep 22 1999, 10:32:58) [GCC 2.8.1] 
     	System Platform: sunos5, Ultra-2  

It seems that if a user hits a page that either does an intense database
query or iterates over a large number of items, all other users are
prevented from accessing any page....! This problem may to be related to
the dtml-in but we are not sure.

For example suppose user A hits the following page (before user B hits
his page):
<!--#var standard_html_header-->
<dtml-in "_.range(999)">
	<dtml-var "_['sequence-item']">
	<dtml-in "_.range(999)">
		<dtml-var "_['sequence-item']">
	</dtml-in>
</dtml-in>
<!--#var standard_html_footer-->

And User B tries to access this page:
<html><head>
</head>
<body>
This is test
</body>
</html>

User B is prevented from accessing his page until User A's page returns.

Please help ASAP

I'm not sure I understand this. Perhaps you could rephrase the question.

We're phasing out hosting in favor of DASH (Dedicated Application Server
Hosting). This is not a price quote: For about $200/mo, you can get a
Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT

The RaQ3 is a Intel-like setup (AMD K6-2, I think). Earlier models used an
embedded MIPS CPU. I have no personal experience with either, but we use a
fair number of them (and some older RaQ models). Zope ought to run just
fine on it, but I've never tried.

I'm doing some Zope development on a VA 500 (dual P-II-350), and we have
two of them for mailservers. No complaints. They come with Red Hat. Using
my own RPMs for now.

Of course, the *other* one needs to allow one to write to the own

Message-ID: <Pine.LNX.4.10.10003291624590.20418-100000@kenny.comstar.net>

Environment: Red Hat Linux/Intel, Zope 2.1.6, GenericUserFolder 1.1.0

Problem: I have a GenericUserFolder in a folder in the root folder. When I
log in to the initial Zope management screen, with a user with both
Manager and Owner roles (andy), I get this as debugging output:

2000-03-29T21:23:04 PROBLEM(100) GUF gudid is   

Even though I am not going into the folder with the GUF. Probably this is
due to just accessing contents information. Note that it says "gudid" and
not "gufid", which is what's in the code, which is a bit odd. It's also
printing some squirrely 8-bit character that doesn't paste in.

The folder with the GUF (XXX) has acquisition turned off for all
permissions, and all permissions enabled on Manager. The GUF itself has
normal security. In addtion to this, the user is assigned the local roles
of Manager and Owner in both XXX and XXX/acl_users. It doesn't seem to
matter whether these local roles are assigned or not.

If, as my user with Manager and Owner roles, I try to get into XXX, this
happens in the debug log:

------

The first three messages seem okay to me. The problem is that it is only
validating my user for the Anonymous role, and from then it seems to be
working as it should: It pops up a login document. The login stuff and
authentication seems to work properly. But it is not getting the correct
Roles from the top-level acl_users. The superuser works as you would
expect, until you look at the debugging info.

The difference here is on the first try (with andy), it crawls up twice
and fails each time, but with the superuser, it again crawls up twice
(gets just the Anonymous role at first), but on the second crawl,
validates the correct roles (note that manager appears twice).

Tracebacks dont look useful, just raising the LoginRequired exception, and
the only reason I have a traceback is because of debug mode.

Is this a bug (whose bug is it, anyway?) or a feature?

(BTW, that's a Python XXX, not a porno XXX. So don't flood the box looking
for pix of hot naked teen action. You won't even find any hot Python
action yet.)

Subject: [Zope] Zope in Jpython
Message-ID: <000501bf99d0$f37f0b60$770da8c0@bbs>

Zope is greate, all reviews say so. Most of the reviews complain the
documentation.

I believe all come to known zope have experience the same difficults and all
those remains can feel the power of zope.

Not only the documentation is matter. Under the greate architecture, zope is
inconsistance, non-intutive, and mistiness.

To be fast to market is not enough, it must also easy to maintain, endure
greate and fast change to make zope success.

To make good use of zope, one should paid more attentation on content
instead of control. Making separation of control and content as deep as
possible. Write re-usable, structural components.

I believe the following is very important :

1. re-introduce unified naming convention. encourage developers to change
over this
2. move un-necessary codes from the zope kernel to user space: <base> <lang>
...
3. support of unicode
4. make zope content easy to co-operative with current technonlgy especially
search engines. zope oodb is greate, but it prevent other apps to access the
data, so it is difficult to contruct a local search facility.
5. support cvs style versioning
6. multiple output format
7. new scripting language, encourage separation of content and control, may
be more xsl and xpointer style.

Converting zope to Jpython have the following benefits:

1. Unicode support
2. draw other java components : for example, several  xml tools being
develop in Apache.org is very useful.

If a complete re-write is not economic, at least DC should consider how to
separate the content and control in zope, make the syntax easy to learn and
use.

Ok, I've got the z sql method & odbc working correctly, and from a screen i
can input a date ( as text string) and product which then returns a nice
 and fast! ) graph of dates on the x axis versus avg values on the y. Now
from the documentation you can only get back 2 variables to use in the graph
but i need to plot about 5 Y values. So i thought about multiple graphs but
can't get that to work either.
    My solution was to create 5 radio buttons asking for what type of plot
they want, then based on the button selected fire off the appropriate
<action>. I'm new to Zope so i can't seem to get the Conditional statement
to work right on the <submit>. Anyone with any experience in any of this
please send suggestions. Thanks.

I have a sprinkling of Pystones for everything from the original Qube to a
P3-700:
http://weblogs.userland.com/qube/stories/storyReader$289

If you're doing any Zope work, you might consider as a minimum a RaQ3. Even
then I would think twice. There's a massive performance boost with the
P3-600 and P3-700.

I don't have any results for a RaQ3, but based on the CPU, it's not at all
an ideal Zope environment.

If you want a fast, cheap, Zope box look at the G3-450s. Even an iMac. Or a
Celeron. But not the Cobalt lineup.

Hi All,

Ive created a Product on my site that clones a file, then changes its
properties and
places the new file into whatever folder Im accessing that Product from.
It was working fine until I moved a bunch of folders. Basically, In the root
folder I
had a folder called website, then within that, folders called topstories,
sports,
weather etc. I copied the topstories, sports, weather folders to the root
directory and
then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to
access
manage_changeProperties". I am listed as a Manager of the site though, and
seem to have
full permission to do anything. I have discussed this with the superuser and
we can't figure
out why this happening.

Hello:

I'm not getting dtml-let. I use it to create a variable that I can access, correct?

Say I want to initialize a counter, and change it from 0 1 each iteration of a loop.

This will print out rows of a table with alternating background colors:


<dtml-let x=0>
</dtml-let>

<dtml-in "getElementsByTagName('book')" >

<dtml-if x==0>
	<tr bgcolor="DDEEAC">
<dtml-else>
	<tr>
</dtml-if>


write out some html

</tr>

<dtml-if x==0>
	<dtml-let x=1>
	</dtml-let>
<dtml-else>
	<dtml-let x=0>
	</dtml-let>
</dtml-if>

</dtml-in>
</table>
</dtml-with>



The let and if syntax is not good, and I can't read anywhere on how you would accomplish this type of
construct.

Few.

> Bad idea? 

Many.

Java is not an open platform.  Zope depends very much on the current
CPython implementation. Java has 'stability' issues, depending on what
vendor/platform/day of the week it is.  No in-house Java expertise.  Add
to this the list of debatable reasons why doing anything at all in Java
is a bad idea.  The bottom line is probably that we don't trust Java
like we trust C and Python.  If Java sticks around for as long as either
C or Python, then maybe I'll trust it a little, but never more than that
as long as it is a closed platform.

>It seems like a natural way to increase the performance of Zope while

Increase?  I think that's highly debatable.  We could put just as much
effort into increasing the performance of the CPython JVM or rewriting
components of Zope in C and probably get a much higher performance
return than depending on any one of a number of wildly different Java
implementations to give us that.

Consistent, everywhere?  This would require incredible re-writing and
probably break alot.  We'd rather come up with some newer, cleaner
interfaces and deprecate the old ones.  You're in luck, because now you
can propose new interfaces and corrections for existing ones, complete
with your prefered unified naming convention at the Interfaces Wiki:

I'm not sure what you mean by user space.  Zope is pretty well
segmented, we do need to clean up the application itself a bit.

> 3. support of unicode

Ah, as soon as python does, we do.  Also, soon there will be a Japanese
Vocabulary to support Japanese searching of text, and after that we are
going to try Chinese.  In Zope 2.2, using these examples, you can create
a Vocabulary object for the language of your preference.

This is kind of vague, nothing in ZODB is specific to the way Zope
stores its objects, currently Zope uses a FileStorage but there is
nothing preventing you from creating an XMLStorage or a
FileSystemStorage or a ReiserFSStorage or what have you.  Doing what you
want here can be done right now, it just has do _be_ done.

> 5. support cvs style versioning

Same as 4, all of the hooks and technology is there to support this, it
just needs to be done.

Can you define this better?

Well, there is some experimental stuff going on, but probably not
anything like xsl or xpointer, more like dealing with templates applied
to textual content that has structure.  Also some people are working on
introducing some more xml based tools in Zope.  Keep in mind also that
all the hooks are there, you just have to come up with an
implementation.  There is nothing in Zope that says you can't look at
the entire thing as XML or whatever, in fact, this can all hapen right
now.

This is one of the few genuine benefits, and soon it will be supported
in CPython so it's not a very pressing issue.

You can still use those components with Zope; why would you want them
all to be in the same language?  If those components have well defined
interfaces that Zope can work with why does it matter what language they
are written in?  I don't see this as a benefit.

Yes, we are working on these issues right now.

<dtml-let> tags only set that variable within the <dtml-let>context</dtml-let>
tags. 

The task you wish to do would much easily done using the variables set by
dtml-in. Eg <dtml-var sequence-index> will print out the 'count' if you like
for the list.

<dtml-if sequence-start> </dtml-if> (from memory?) will evaluate if it is
the first iteration of the loop.

<dtml-if sequence-even> and <dtml-if sequence-odd> will evaluate odd and
even iterations of the loop, which is what it apears you want todo.

Check out the zope quick reference document for documentation on
this

To concur with Michel --  JPython is a wonderful java prototyping
environment.  I know that people use it to do real work, as well...

But, I'm really not sure that it gains you much, given Java's high
footprint on anything that is non-Windows/non-Solaris.  

Also, JPython loses some of the nicer features of python (such as
multiple inheritance; at least the more recent functional versions
did, last I looked, 6 months ago).  This might be problematic,
depending on the guts of Zope.

If you really want Java, I suggest sticking with Servlets.  Or fork
the source code... 

But Digital Creations, please don't reimplement Zope in JPython...

best,

Let me warn you, you are allready thinking too procedurally.  Remeber
DTML is a _template_ language.

Let defines a new scope for variables, the scope being defined by the
let block.  Each time you use the let tag, you are creating and then
immediatly destroying the scope of your variable.  If you want to use
'x' in your DTML code, that code must be contained in the let block that
defines x.

What you are doing is easily done using the 'sequence-even' attribute.

<dtml-in "getElementsByTagName('book')" >
  <dtml-if sequence-even>
    Print stuff for even rows
  <dtml-else>
    Print stuff for odd rows.
  </dtml-if>
</dtml-in>

Message-ID: <38E2BA94.FF282F9B@suprize.com>

Hi,

    Since zope was introduced, I've created a handful of objects in
the nice application server and make great progress on several projects.
Thanks to DC and supports from people in this forum.

    Lately, these handful of objects keep growing and, from time to
time, I need to use find an object ID based on my vague memory. The
"find" tab in the zope interface grabbed my attention. But it seems
only accept full ID name to be put in the search field. Is there a way
to let "find" search by pattern or wild card characters? I've tried
*<pattern>%, %<pattern>%, or just <pattern> but with no luck. Please
advise and sorry for my bad memory for which only part of the names 
can be kept for a short while.

However neither of the above works, the latter gives a traceback error,

The above is used inside a DTML Method which is called by passing parameters
to it from a DTML Document. qry_name is one of the parameters being passed.

Any help appreciated.

etcUserFolder is an older piece of unsupported software that may have
compatability problems with newer versions of Zope.  I don't know if
anyone out there maintains it actively.  Without similar reports I would
tend to believe that this is because etcUserFolder has not be changed to
reflect recent changes in the API.

You can do some string matching with the 'expr' field, this lets you
type in a python expression that is evaluated against each object, for
example "id[3:] == 'bob'" would match all objects beginning with 'bob'. 
There is no regular expression facility.

This probably won't be expanded on because to a point the find tool just
doesn't scale.  If you want advanced wildcard searching of textual
content, use a Catalog.

I think it's a thread problem but not anything linux related, or at
least I'd need to see proof of that.

Wait another day, and try -t 2.  See what happens.

I wonder if the fact that manage_changeProperties was a latecomer to
security makes it different in other ways.

Subject: [Zope] Problems using DateTime in dtml and python. Help...
Message-ID: <38E2F888.51937800@ne.mediaone.net>

I have been building an interface for call reports from a MySQL database
on linux slackware 7 using
recent source distributions of Zope ,MySql and python. Besides a messy
bout with the ZMySQLDA
source, which is now not an issue,  I've  done OK. The problems:

1:

  I can call the DateTime() function from dtml like this-
    <dtml-var "_.DateTime(a_later_time) - _.DateTime(an_earlier_time)">
and I get what I need - a duration of time- but in days.  Is there a
method to change this to
minutes and seconds or do I just do my own math ... result * 24 * 60
etc... Whenever I try to
use the  DateTime  objects, eg fmt=DayOfWeek etc, I get invalid
attribute errors.

2:

I would rather do this work in an External Method, but when I try to use
DateTime() in a method
I get a Name Error when I try to update the Eternal Method in Zope.

So I went  to the python command line.
>>> from DateTime import *
Traceback (innermost last):
 File "<stdin>", line 1, in ?
ImportError:No module named DateTime

Obviously, I have some work to do, but what ? Recompile Python or Zope ?

How do I get DateTime to be recognized as a module?
I noted that the contents of  the Setup file in
/Zope/lib/python/DateTime are commented out-
 # install DateTime.py
 # install DateTimeZone.py
I uncommented them for kicks and reinstalled Zope with the same results.

It seems to me I'm missing something OBVIOUS.
And help greatly appreciated...

A GUF object has just been instantiated. The squirrely character needs

Its a bug. I'm putting together a patch release as we speak, and I hope
to have this fixed (next on my list). I was hoping that the 2.1.6 release 
would make all this crawling-up-the-tree business unnecessary but the 
change proposed doesn't seem to have been implemented.
(see http://lists.zope.org/pipermail/zope-dev/2000-January/002940.html )
I vaguely remember that the LoginManager for the PTK was going to make
use of this, but I havn't had time to pay attention for the last month or
so :-(

The Anonymous role being returned the first time is a recursion check
kicking in - during the authentication stage, we need to access your
methods in the GUF, which kicks in the authentication system again...

My bug.

I need to get the ZCatalog to update it self when I do new postings.
I have tried this

<dtml-call "Catalog.manage_catalogFoundItems(REQUEST, RESPONSE, _, _,
obj_metatypes="MyClass")">

But I'm not sure about the REQUEST and RESPONSE...

Subject: [Zope] problem with dtml-if
Message-ID: <v04205500b508b9940b8b@[130.227.115.56]>

hi,

I have this code in a dtml method called "test":

<HTML><body bgcolor=#ffffff>

<form action="test" method="get">

<SELECT NAME="day">
	<dtml-in 
"(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26 
,27,28,29,30,31)">
		<OPTION VALUE="<dtml-var sequence-item>"<dtml-if 
"_['sequence-item'] == day"> SELECTED</dtml-if>>
			<dtml-var sequence-item>
		</OPTION>
	</dtml-in>
</SELECT>

<input type="SUBMIT" name="SUBMIT" value="go">
</FORM>
</BODY></HTML>

It should "remember" the day selected and choose that as the default 
when making the select box. But for some reason the sentence:
<dtml-if "_['sequence-item'] == day"> SELECTED</dtml-if>

Doesn't work. I have also tried ... == _[day] ... == 'day'
...and a lot of other stuff but with no positive result.

I start the page with zope:8080/test?day=1

Regards

What can I do to logout with standard basic authentification?

[exec. summary -- concurrent requests becoming serialised; suggestions]

Hi,

I ran your test script on our zope server, and managed to view many other
pages while zope was parsing the page...

It looks like you might not have enough available threads (or maybe database
connections?). 

It's strange that only one request at a time is processed -- are you perhaps
using Zope in single-threaded mode (using pcgi_publisher; see
doc/WEBSERVER.txt for details)? You can set the number of threads Zope uses
by changing NUMBER_OF_THREADS in Zope.cgi; the default is 4. Note that
increasing this number will also increase Zope's memory footprint, as each
thread gets its own copy of the persistent object space.

It may also be that your machine is simply choking on that test script -- it
takes a while for zope to parse and render it. Despite python switching
between threads every n bytecodes, such a script (rendering one million
items) is going to put quite a load on the machine!

On your database queries you may be using a database adaptor that doesn't
give up the global python interpreter lock during transactions. This
prevents other threads from executing. What database and database adaptor
version are you using? See http://www.zope.org/Members/petrilli/DARoadmap
for details. There is a brief description of why the interpreter lock exists
in the python FAQ, section 4.88 (http://www.python.org/doc/FAQ.html#4.88).

Although unlikely with only one user, it's also possible that you could be
running out of database connections. By default, a maximum of seven
connections can be opened to any database you add. This limit can be set by
adjusting pool_size in zope_dir/lib/pyhthon/ZODB/DB.py (later versions of
Zope allow you to tweak these things in a custom_zodb.py file; try searching
the mailing list for details). Note that increasing pool_size will again
increase Zope's memory footprint, as query results are cached on a
per-connection basis.

hth,

Hope this is not too stupid a question:

How do I test a version without saving changes?

When I use the view option from within the management interface I only get
to see the 'live' (ie public) version and not the version that I'm working

Hi,

With basic authentication, the user's browser caches the username and
password, and sends them along with each request. All you can do to
invalidate the cached values is raise an "Unauthorized" exception.

<dtml-raise type="Unauthorized">
 You have been logged out. Please log in again.
</dtml-raise>

This sends an HTTP 500 Unauthorized back to your browser, which should
display the basic auth. login box again.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.12.html for
details.

Try:

_['something'] means I want the value with the literal key of 
something.

_[reftosomething] means I want the value with the key which is the 
value of reftosomething, if that makes sense.

The problem with this is that the browser will not clear its cache of this
valid username/password unless the user clicks 'OK' on the login dialog box
that pops up.  If the user clicks 'Cancel' then the browser assumes that
the user doesn't want to change the username/password, and keeps the
existing one in cache, hence, a reload of the page will be successfull.

Does anyone know of any tricks to get around this?

Hi Jonathan,

You might want to check with the ZIP - Zope Internationalisation
Project. There was some talk about a word by word translation service
lately. You might find interested partners there! You can find the
ZIP-Maillist home at <http://www.eevolute.com/mailman/listinfo/zip>

Really? What would you put on the Macs? Linux, OS X or MacOS?

What makes the Celeron superior to the Cobalt-setup in your opinion?
I thought the Cobalts where rahter high-speed (full) pentiums and
that the Celeron is not well suited for server use??

In my browser (Netscape) this works if you're following a link after
aborting this process.
Another (not very nice) method is using java-script closing the windows.
Recently found no better hints.

Thanks for pointing that out. 

As I understand it, this is a limitation of the HTTP Basic Auth. spec. RFC
2617 deals with this, and says that a client may preemptively send the Auth.
header with requests without receipt of another challenge (section 2). The
browser sends this information for every request in the zope realm (if it
didn't, you'd get the login box on every page). The server also sends an
authentication required header for every page that is protected, so this
behaviour in fact is quite logical.

The only way around it is to use a different authentication mechanism, like
Generic User Folder, et al.

Oh, yeah, and I meant 401 Unauthorised... what a week...

So, ZTables is going to die silently? I don't know much about it, but
considering the number of times I use TinyTable I would say that
ZTables is a needed datastucture for handling larger amounts of data.

Of course I understand and encourageDC to sell it as a commercial
extension, but I have problems understanding why they don't release it
to
the public if they lost interest. Anyone from DC?

Hello!

My current ISP has no interest in supporting Zope and will not install some
kind of 'Long Running Process', so I can't install it myself...

Can someone recommend an ISP that supports Zope?

I found Armored Internet, but it seems like they only support Zope for
Business Services (and they also charge $37.50/month for it). So if someone
knows an another ISP, preferable cheaper, PLEASE let me know!

Hi,

I have learning Zope for 6 months and have been
following the mailling list. I come across the
following news :  

Python 3000 will not be backwards compatible. 

Question :
How will it affects Zope ?

Sorry to be picky here but, quoting from Table 15 on page 21 of the DTML Guide:
missing - Provide a value to be used if the ariable(sic) is missing, rather than raising a KeyError.

This is what I ended up doing :-)

Is it just me or does it seem silly that:
<dtml-var HTTP_REFERER missing='/'>
works as expected but
<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>
doesn't, even though they're logically the same thing?

The KeyError should be caught when evaluating the expression as well as the name in dtml-var :(

I might chuck this in the collector at some stage...

That's because 'day' in the request is a string which you compare to an
integer.
Try:

<dtml-if "_['sequence-item'] == _.int(day)"> and your code should work
fine.

BTW you can shorten you <dtml-in> statement with the range tag:

<dtml-in "_.range(31)"> will give you the same output.

Zope won't run on MacOS. It would have to be either Linux or OSX or BSD.

It runs Python faster than a PIII of the same speed. I'm assuming that's
because the cache, while half the size of a standard PIII, runs at full CPU
speed. That it supports only a 66MHz bus and memory may cause it to not
perform as well under load. I don't know. I  don't have the resources to
test that sort of thing properly.

There's more to a building a server than its Pystone rating, but it's a
start when you start looking at putting together a box.

Subject: [Zope] variable SQL insert method
Message-ID: <38E3368A.98950BF0@rrsg.ee.uct.ac.za>

Hi,
I have a database with 3 tables. I would like to create a ZSQL method
for inserting data into the tables. I started by creating a separate
method for each table, but that seems a bit of a waste. Ideally I would
like to have one method, "addEntry". The template would look something
like:

<dtml-if "tname=='supplier'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar sup_name
type=string>  etc...);
<dtml-elif "tname='manufacturer'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar man_name
type=string> etc...);

</dtml-if>

The problem is that I have to specify the arguments in the argument
list, and the arguments are different for each if clause in the above
code. Is there a way around this?

thanks
Allen

if get_returner_id(xxx) returns an empty list, then it _should_ return
nothing.

as the <dtml-in will be executed 0 times.

(untested, and will need finishing off)

Put ALL the arguments in the ZQSL method's arguments section, but give them all defaults (eg put
myvar_name='' in the arguments section)

Now, to make sure the right ones have been supplied, you need to put in an extra level of dtml-if in
each branch of your current dtml-if, something like:
<dtml-if "tname=='supplier'">
 <dtml-if "_.has_key('var1') and _.has_key('var2')">
  ... your insert here...
 <else>
  ... do something to warn of the error, such as a dtml-raise
 </dtml-if>
<dtml-elif ...>
...

Hi,
I just ./stop and ./start'ed two Zope servers that were taking up 
rather a lot of memory;

   PID USERNAME THR PRI NICE  SIZE   RES STATE   TIME    CPU COMMAND
   841 nnle      12  33    0  395M  318M sleep 177:24  0.00% python
   834 nnle       9  23    0  531M   14M sleep 101:20  0.00% python

Is there any way of telling what objects are taking up this memory - 
could it be a memory leak in Zope at all? I'm using src-2.1.3 on 
Solaris because I still use the /REQUEST hint to see what my 
variables are.

cheers,

Now - LinuxPPC (my Mac at home that gets 900 pystones is usable for 
me to do dev work on).
Later - choose from OS-X or LinuxPPC
You can't (easily) use MacOS because Zope has some unix-centric parts 
that don't translate well to the Mac.

>What makes the Celeron superior to the Cobalt-setup in your opinion?

The Pystone scores are higher
Celeron-400a
Pystone(1.1) time for 10000 passes = 1.78
This machine benchmarks at 5588.87 pystones/second
vs
Qube2
Pystone(1.1) time for 10000 passes = 8.81
This machine benchmarks at 1135.07 pystones/second

Sorry, not qualified to answer that bit. All I do know is that we 
have a 700MHz PIII here that gets 10,500 Pystones against our 
Enterprise 450 with ... 2700. As the maintenance on the Sun kit is 
roughly the same price as the PIII, you could say I'm not overly 
impressed with the Sun...

Hello,

I've just discovered Zope, and would like to get more information about it
as it
seems quite interesting . But I'm not sure I could use it for the web
project I'm
working on.

First, I'd need to stock XML files in an object database like the one
provided with
Zope. What kind of requesting language may I use ?
XQL ? Xpath ? XML-QC ? OQL ? XOQL ?

Second question, is there a java API integrated in Zope ? If not, is it
possible to
interface Zope with others java products as Resine, servlet engines, EJB
server...?

Thanks in advance

Bruno Faure

Subject: [Zope] dtml-return'ing the result of a SQL select (does not work)
Message-ID: <38E35092.A8838265@knoll-is.de>

Hi,

I just tried to implement something as described in the How-To
	How To: Use GenericUserFolder with an SQL database
It does not work. The problem boils down to the fact that I can't
dtml-return the result of a SQL query.

I wrote the Z SQL Method 'qryTest':
	select * from mytable

This method can be executed without problems. It displays all rows in
the table.

And I wrote a DTML Method 'returnData':
	<dtml-return qryTest>

When calling the method I get
	Resource not found

Traceback (innermost last):
  File D:\Programme\uZope\lib\python\ZPublisher\Publish.py, line 214, in

Watch out, this might be confusing, since Subscribe is a permission
referencing in the other direction (eventually actually needs to be
placed somewhere seperately). You have to set that checkbox in the 
account, that is supposed to access that data in it's default view,
or in that account session you must use the "Go-control" to switch to
the shared account.

Does the method return the full text if you call it
directly?

like:

http://your.zopeserver.dk/yourZclass_instance/PrincipiaSearchSource

you should get the raw contents of the instance..

If you don't , somethings wrong with the method or its
placement..
i think product/product_entry/methods is the right place..

If you get the raw text returned, the fault is with your
Zcatalog.. Have you updated it after adding the pythonmethod
??
- Checking the status-view of your zcatalog can often help to see
if it has updated correctly..

Subject: [Zope] ZSQL arguments
Message-ID: <E12afEQ-0004UC-00@marvin.nipltd.com>

Hi,

ZSQL methods can have two types of string argument, string and 
required, where required is a non-empty string and a string is (one 
assumes) a potentially empty string.

Although does not say in the ZSQL users guide, it would be nice if 
strings were also not required to exist as arguments, which to my 
mind is the logical progression of allowing an empty string.

The reason I want to do this is that I am writing sql methods which 
build queries based on the existence of certain arguments.  
Obviously I can code the logic to test for empty strings, but it 
would be neater and simpler to be able to simply have

<dtml-if myarg>
...

The other reason this would be a neater solution is that it would 
avoid the need to set up lots of empty arguments in the dtml which 
calls the sql method.

Comments?

Cheers,
Stephen

Sorry, Tom,

I was blabbering last time about hasattr. The right solution is of course:

def recursiveMethod(self, obj, result):
     if hasattr(obj, aq_parent):
            result.append(obj.title)
            recursiveMethod(self, obj.aq_parent, result)
     return result


which you will have to call like this (assuming you external method in Zope
is called recursiveMethod):

<dtml-var "recursiveMethod(<obj>, [])">

Working with a keyword argument didn't work for me. I'm sure someone can
explain you why (but I don't have time for sorting that out right now)

Zope returns a key error on "set". The same appends for 'append' method, as if,

I eventually found the answer by creating an external method :

def SetValue (self, dictionnary, key, value):
    """Ajoute une valeur ŕ un dictionnaire"""
    dictionnary[key] = value


Which you can call with <dtml-call SetValue (REQUEST.form, 'tata', 'titi')>. It
works !...

*Increase* performance by rewriting in Java?  You've been reading
Sun's press releases again and, worse still, actually believing them;
don't make that mistake! :) 

I can think of any number of improvements that could be made to Zope,
but a translation into another language, with no clear idea of what
actual problem would be solved by the translation, isn't one of them.

	Also, take a look at: www.step-thermodynamics.com

	Their primary business is selling specialized cooling systems
	for processors, which they bond to the processor.  As a result
	they only sell their cooling system with a processor.

	They provide a lifetime guarantee on what they sell, and they
	also guarantee that a processor will run at a specific MHz
	(which in the case of a Celeron 333a processor is 500 MHz if
	I remember correctly).  That particular configuration uses a
	100 MHz front side bus speed.

	A friend of mine has got a couple of dual processor boxes with
	Abit BP6 motherboards (socket Celeron motherboards) with two
	Celerons each running at 500 MHz.

	For any task that requires fast cache, but not a lot it, they
	are great systems.

Ok.. so I opened up a can of worms.

Thanks to everyone for setting me straight. I do think, though, that
performance and benchmarking should be an issues on the tips of DC tongues.
I have been doing a lot of benchmarking (and will publish results soon)
trying to figure just where the bottlenecks are (DTML, references, SQL,
size, caching). The good and bad news is that there seems to be no
difference in many of the different tests. I can get a MAX of 40 requests
per second, and that, is that.

The reason I asked about JPython and performance was because I get a lot of
developers telling me that Servlets are much faster. Now, that being said I
am about to set up a website with servlets and pound on it till it bleeds to
see if it is true.

One of the comparisons that would be nice on Zope.org would be the servlets
vrs Zope. (JServ, Enhydra, etc).

Thanks,
J

Hi,

I ran into trouble when trying use PIL (python imaging lib) in zope
product. 
The problem is that zope's App.ImageFile is used by PIL's internals
instead of PILs ImageFile and of course this doesn't work.

Any ideas how to fix this problem?

Sure. You just need to 'packagize' PIL. 

Place the PIL directory somewhere in your
Zope's python's path. Add an __init__.py
to the PIL directory.

Inside the __init__.py place the following:
# Add any additional PIL modules that you want imported.
# This is one, long import statement that my email clien will
# wrap.
import Image, ImageFile, ImageEnhance, ImageDraw,  _imaging, GifImagePlugin, 
JpegImagePlugin, PngImagePlugin, BmpImagePlugin

Message-ID: <38E37C81.365E6845@knoll-is.de>

Hi,

I just found something in DT_Var.py which I mean is a bug.
The function thousands_commas uses a hard coded ',' to as thousands
delimiter. I think it would be best to use locale.format instead for
this purpose.

Is there anybody how can incorporate this change into Zope?!

One more related question: How can I print the current currency symbol
in Zope? I could not access the locale namespace in a dtml method.

Thank you.

I can think of one: I wrote my first program in php in some minutes, while
my first zope silliness took me days.

 - BUT -

now I'm in this mailing list so I can flood you with questions.


Please keep in mind that I'm a total newbie, at the moment I know
little more than Nicholas Petreley about Zope. I'm fluent with python
and slow but steady with html.

My first site is for an antique trader (my father): four languages,
lots of photos with descriptions, some search methods, some registered
users, a private addressbook.

There will be an "uploader" interface for my brother, a public and
a "frequent customers" interface. I don't think the Photo product
is stable enough for use, so I'll try and write something by myself.

If I use a "pure" zope provider, do I need to keep the photos on
the ZODB?

Is it possible to write to the file system via an external python
method, so that I can:

 * receive a photo with netscape
 * give it an unique filename
 * write it to the file
 * update the info (filename, descriptions) on a SQL table

 and then

 * reference (from DTML) or delete (from python) the photo by the
   filename stored on the SQL table

 ?



The trouble with Zope is not that it isn't documented, but the
documentation at first makes me fell stupid. I don't know why.

It is like loving a girl you didn't have the chance to talk to.
It makes me feel stupid.

Maybe the fact that I need a 21" to look at my source, and I have to
look at the source of the page returned by the browser to see the
stack trace with my error (when there is a stack trace), has something
to do with the stress I am having during my learning sessions.

Will zopezilla (or mozzope)? enhance my Zope Experience?



Thank you for reading this far.

Subject: [Zope] namespaces and uploading files etc
Message-ID: <38E37FB9.25E18857@rrsg.ee.uct.ac.za>

Hi,
I've written an external method that will write some data to a specified
location in the server's file system. I would like a user to be able to
upload a binary file, and for the external method to then write that
file to the local file system. I understand that when a user uploads
something using an <INPUT TYPE="file" NAME="uFile"> that the file is
encapsulated in a FileUpload object. That data would be accessible in my
external method using REQUEST.uFile.read().
However, suppose my external method is defined as :
def writeFile(self, file, rootdir, filename):
    ...write data using f.write(file.read())
    return filename

I would like the argument "file" above to be a reference to
REQUEST.uFile. Also, the "filename" that is returned would be the actual
filename used (it may have been altered due to filename clashes or
whatever).
I tried using the following dtml to call this method:
<dtml-let filename="writeFileLocally(_.None, _, _.uFile,
  '/usr/local/ZopeExternalFiles/Components', _.uFile.filename)">
<dtml-var filename>
</dtml-let>
However zope complains...
I'm obviously still fumbling with zope's namespaces.

Thanks
Allen

Comparisons of this type are always quite difficult to pull off. I know that
the applications I've created are rather Zope-specific. I designed them for
Zope and they take advantage of Zope's features. It would be really
difficult to try to do a reasonable comparison, because Zope has features
the other systems don't. Sure, I could make a servlet that acts kind of like
an app of mine, but how would I simulate retrieval of data from the ZODB and
acquisition and the like?

I'm sure that I'm paying a performance price for things like the ZODB and
acquisition... but I think that price is offset by the productivity
improvements that I get as a result.

Convert the DateTime objects to seconds before subtracting::

  <dtml-let early="_.DateTime(an_earlier_time)"
            late="_.DateTime(a_later_time)"
    <dtml-var "_.float( late ) - _.float( early )">
  </dtml-let>

You can use '_.int(..)' or '_.long(..)', to, truncating to whole seconds.

Put an __init__.py in the PIL file that says:

import Image, ImageDraw 

and have it import whatever you need from pIL.

Then you can just do 
	import PIL
in Zope.


The Poll Product has some instructions on this.

I have a zope ISP (hurrah.com) and am trying to determine how fast/reliable
they are.  Is there a way to compare Zope ISPs for speed and reliability.  I
would imagine speed is the easiest to test and reliability is subjective and
based on historical knowledge.  I am just having trouble telling if my test
version of Squishdot (and my test site in general) is really supposed to be
as slow as it is.  I am used to working with a large ISP (Verio) with no
Zope.

Any ideas on how to compare or test would be greatly appreciated.

Isn't it 32kb for Postgres?

Unfortunately, the photos are up to 350kb.

Ok, ten smaller objects could do :-)))

Subject: [Zope] Date Zone Problem
Message-ID: <20000330165619.76957.qmail@hotmail.com>

Hello,

Last March 26th Portugal changed to GMT+1.

ZopeTime() returns, for instance, "2000/03/30 16:00:00.000 GMT+0".

16 hours is correct but I think it should give a GMT+1 at the end of
the date?

I found this because I'm having this problem:

I have a object with a property date that when created first time
with the factory add method uses the manage_changeProperties with
the date value added to request with,
<dtml-var "REQUEST('date',ZopeTime())">.

The object is cataloged. Then I make a search to get the objects and
sort them by date. When I render this objects dates If I format the output 
using fmt="%C %Style" the date presented is "2000/03/30 15:00:00.000 GMT+0", 
one hour less!!

Since this is not right cause the real hour is 16 I work around the
problem and discovered that the TimeHours() function returns the correct 16 
hours. That resolved my output problem.

But then again a problem emerge. I have a form to update my objects 
properties, in this case, the date property. This form when rendered
writes a <input type=text:date name=mydate>. When submited a strange
thing happen. If I output the date of this updated object with the
fmt="%C %Style" format the hour will now be correct, i.e, 16.

I though then that the "text:date" type in the html was important for this 
happening.

But the problem now is that when sorting my objects this one will be sorted 
using 16 as the hour but other objects that I did not updated, i.e, dont 
passing them trough the "text:date" form, will be giving 15
for the sort.

Questions:

Is this a internationalization of zope related problem?
Does the GMT+0 instead of GMT+1 is a zope/python bug?
Am I missing something about the international date zone system?

Best Regards,
Julio

I did a private extension to DT_Var.py which incorporates 
the modifier "german-money", which returns 
1&nbsp;234,5 for 1234.5 
Just because I needed it.

I did not mention it to the group since I want a much cleaner and more
general approach for supporting multiple languages.
I dont think we could handle this with locale, since the actual page
could be in a different language.

I've since moved back to 2.1.4 and it works fine there. Will be setting

Can you tell me what products? I know that if you are using

then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to

No, Zope can't, especially Python can't, because it trys to evaluate
something like sequence - item.foo.

So try

<dtml-with sequence-item>
 <dtml-call "foo">
</dtml-with

or:

<dtml-call "_.['sequence-item'].foo">

I've had exactly the same problem. I put 2.1.6 and it breaks (user
authenication), I put back in 2.1.4 and it works fine. I'm also just
using straigt Zope. Just so you know it's not isolated.

Too much effort to fix it.  We don't have the time, we are working on
too many projects as it is, even discussing ZTables takes more time than
we have.

Releasing it to the public would still take time, someone would need to
maintain it, but to maintain it they'd first have to understand it, it's
complex; as complex as the catalog.  If we threw it out to the community
I suspect it would die there also.

Besides, TinyTables could be updated to support more efficient data
structures like the BTrees that ZTables and ZCatalog use.  ZCatalog + a
more efficient TinyTables is probably 99% of ZTables.

If one makes heavy use of TinyTables but needs more functionality (but no
RDBMS) I suggest he/she takes a look at Metakit. (www.equi4.com). This
amazing software deserves more attention than it gets and has already a
very nice interface to python. Returned rows behave more or less like
Zope Record objects. You can do sophisticated stuff like joins
selects etc but it can also be used in a manner similar to TinyTable. It
is transactional and *very* fast/efficient. Currently in not multithreaded
so one needs to serialize requests. I think the author, Jean-Claude
Wippler mentioned that he is working in a thread safe python version (the
TCL one is out).

A Zope interface would have beed nice ...

yes, only in pythonish these are called attributes.

Hm, I tested it. It works for me. Can you tell me where it doesn't work and
in what way? Does it fail. Is there a traceback? Remember it will still bail
out (with an AttributeError) if the object has no attribute title!

That is because there is no high level framework with servlets.  There
is no standard authentication framework, acquisition framework, standard
object/relational model, template language, through the web managment
system, object publishing over multiple protocols... servlets don't come
with an HTTP, FTP, PCGI and a FastCGI server.  All of this you get with
Zope out of the box.

It may very well be.  With the subsequent open sourcing of ZEO however,
you could scale your Zope application invisibly to a hundred machines,
how far can  you scale that Servlet without making any changes to it at
all (or not paying money)?  Requests per second is only one tiny factor
of scale, and when you scale beyond a handful of machines it becomes
less and less important.

That's because Zope can't write it (that's what the 'w' means).  The
user you are running Zope as (if you are root, Zope turns itself into
nobody) does not have permission to write to your var/ directory.
 
> Q1.  Why is Zope looking for Z2.pid if I installed it WITH PCGI?

The Z2.pid file contains the process id of Zope, it allways writes it
and has nothing to do with PCGI.

> Q2.  If Zope still needs Z2.pid with PCGI, how do I get the file there?

Zope will put it there if it can write to the var/ directory.

Though I haven't seen any clear statement to confirm this, I believe this
is a very large part of DC's decision to release ZEO. By enabling Zope
clusters ZEO addresses pragmatically several limitations inherent in the
curent state of Zope / Python. As a side effect, redundancy brings with it
answers to concerns regarding reliablility, of hardware, if not Zope
itself, in a mission critical setting.

While some may see throwing hardware at performance / reliability needs, as
inelegant at best, to others with hopes of rolling Zope out for the long
term, this seems like a perfectly reasonable solution. Python and Zope will
continue to improve, and all Zope users will benefit. For now, leveraging
commodity priced hardware is actually about as elegant as it gets.

So, DC has heard and answered, and Zope is the better for it!

The FileStorage format is portable across platforms.  The objects in
that filestorage are portable across Zope, _as long as_ your target Zope
has the same products installed as your source Zope.

Hm. In the example

<dtml-in list>
  <dtml-var foo>
</dtml-in>

the iteration will change the namespace to that of each sequence-item
automatically. So the foo asked for will always be the foo of the current
sequence-item. Things like
<with sequence-item> or "_['sequence-item']..." are not necessary.

If you iteration is by a number of IDs, as your question suggests, though,
the example is not enough. When you iterate over a list of IDs, the
sequence-item will be an ID (that is a string) and foo will have no meaning
(it will throw an AttributeError).
There are two way of remediating this:

preferrably use objectValues(), like so

<dtml-in objectValues>
   <dtml-var foo>
</dtml-in>

If you _have_ to use a list of ids, things get more complicated

<dtml-in Ids>
  <dtml-var "_.getitem(_['sequence-item'].foo)">
</dtml-in>

(sorry about that)

All code is untested, but it should work.

OK, this is probably a stupid question, but how do I fix it?  I tried:
changing the /Zopedir/var/ folder and file settings to user=ewalstad,
group=users and had no luck running ./start.  I also tried copying one of
the other .pid files and renaming it z2.pid; that didn't work, either.

Any advice is appreciated.

Replying only to the last sentence:  Add a DTMLMethod in the root of your Zope
(call it maybe "debug_request"), with the following body:

  <dtml-var standard_html_header>
  <dtml-var REQUEST>
  <dtml-var standard_html_footer>

This works fine on 2.1.4+ -- they only suppress the "direct traversal" of
REQUEST.

Hello all. I'm just starting my first Zope site, and I'd like to create
a feedback form for the site. I have very little "useful" experience
with DTML, especially for logic. Once I create the form, how do I write
a DTML script to process the input (like linking entries to variables,
testing valid answers, raising errors, etc.) ANY help whatsoever would
be greatly appreciated, and all the useful stuff I learn I'd like to
make a how-to from. Real world solutions like this in Zope are few as
far as documentation go....

thanks in advance,

Eron

Access to a version is based on a cookie set in your browser.  So
when you go into the version object and click on work in version,
the cookie gets set.  If you then access your site from that same
browser session, you *should* see the version.  This, at least, is
how it works for me <grin>.  You should see the version on the view
tab, too, though, so I think you must have some problem with your
browser sending the cookie.

Hello everybody!

Please join me in welcoming Shane Hathaway to the Digital Creations
team!!

From Shane's man page:
"""
I come from a small but growing town called Magna, Utah. I
always considered it an underrated city in the Salt Lake
Valley.  I enjoyed my friends and neighbors there and some
of them keep in touch even now.

I have been programming since I was eight years old.  I
enjoyed the Commodore 64 so much that television I still use
is actually a Commodore monitor.  I had to learn to program
early because my parents refused to buy any software--if I
wanted software, they said, I'd have to write it myself. So
I did!

I enjoy singing.  I have sung in many choirs over the years
including the Cyprus High madrigals.  I have sung enough
solos for various functions that it's now easier for me to
sing a solo than to give a speech in public.

If you ever want to butter me up for something, give me a
genuine Brazilian feijoada.  Include every part of the pig
but avoid the hairy stuff.  Having spent two years there, I
hold Brazil close to my heart.

Not long ago I wrote Web Academics
(http://www.webacademics.com), software for delivering
courses over the web.  It was designed to handle specific
needs requested by educators as well as the needs I was
aware of as a student.  I am working on porting the
education-related components of Web Academics to Zope.

Zope and Digital Creations are very interesting to me
because the product is built on solid foundations and the
company is built on a solid philosophy.  I am excited to
begin working with the team.

Subject: [Zope] Mysterious Netscape Upload failure
Message-ID: <38E3CED8.E4A2561D@palladion.com>

After banging my head on it for a couple of days, I just resolved a really ugly
problem for any Zopista who uses Netscape:  any form which contains a file
upload button was timing out, failing to send data to Zope (e.g., I couldn't
create DTMLMethods!).

The underlying cause of this was Netscape's poor tempfile hygeine:  their file
upload control handler was creating tempfiles, which it then never bothered to
clean up.  Eventually, it exhausted the tempfile namespace, at which point it
looped pointlessly trying to create a tempfile with an unused name.

I tried several reinstalls, tweaked preferences, all to no avail.  The solution
was to scrub the temp dir of all the ns*.tmp files -- everything is hunky-dory,
now.

Looking-for-the-voodoo-doll'ly,

Tres.

Additionally, I would suggest removing the "Acquire Permissions Settings" from the 
"View" permission, and making the "View" permission only available to managers.

This is easy to do, assuming you called the DTMLMethod above "debug_request" and
created it in your Zope Site Root, then you could:

1. Navigate to http://mysite.com:8080/debug_request/manage_access
2. Scroll to the bottom of that long page.
3. Uncheck "Acquire Permissions Settings" next to the "View" Permission/
4. The "Manager" box should already be check, verify this.
5. Click the "Change" button near the bottom of the permission list.

Forgive me if I over-explain.

Message-ID: <200003302208.PAA10382@ifopen.com>

I've got a simple python class that has a data member that holds a list of 
strings (among other things).  I can laod values into this list fine.  
And can query the object and the list is populated.  However, after  I 
restart Zope,  the list for the class instance is empty.  The other data 
values in my class retain their values just fine.

I've got other classes that hold similar lists for which this doesn't occur.

I'm banging my head against a wall - any ideas?

Lets see here ...

KnowledgeKit
LocalFS (installed, not currently in use)
SybaseDAv2
PSQLInput
Cookie Cutter (likewise not in use)
TinyTable (see above)
A small,simple 'nes article' product
Calendar
Standard Zope stuff

That's it.

It is it's own server, so no need for SiteAccess.

In a word, yes. :-)

Here's how I do it on my site. This line tells me when a particular object
(a file object as it turns out) was last updated:

<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=Day>,
<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=pCommon>

The output looks like (for example):
Tuesday, Mar. 7, 2000 11:35am

The extra '_' business in my dtml-var tag is necessary because my file
object has a '.' in its name. I believe that

<dtml-var "spamobject.bobobase_modification_time()" fmt=Day>

should do it if you don't have a '.'

HTH,
Tim

I think you'll find the How-To on creating a mail form very helpful. You'll
find it at http://www.zope.org/Documentation/How-To/Mailform

Good luck.

Thanks, this is what I was looking for. I was adding object names on the the end of it, rather than

I followed the instructions in PIL.  I created a directory called =

I removed the zope/bin/python file, and changed the start file to use =

You're probably mutating the list without informing the instance that you've
changed it.  If you do:

thing.stufflist[4] = 'newstring'

or

thing.stufflist.append('newstring')

...then 'thing' has no way of knowing that 'stufflist' has changed, unless
you replace 'stufflist':

# This can be confusing, since it doesn't look like it does anything
thing.stufflist = thing.stufflist

... or tell 'thing' explicitly:

# This is the official interface to mark an object changed
thing._p_changed = 1

Your changes will also get saved if you happened to change any other
attributes of 'thing' in the same transaction, but as you've discovered this
is unreliable at best.  Explicit is better.

Cheers,

After a minute or two, the directory listing shows up.  Clicking to edit a file

Just on this subject :

a) You may find the Perl mandarin text-splitter at www.mandarintools.com
   very useful. I rewrote it in Python once but my Perl sucks so you may 
   wish to do this yourself. Otherwise, e-mail me for copy ... it's so 
   short I'm sure you'd rather not trust mine though.

b) What algorithm do you use in your searching of text ? Is it just a
   simple frequency tally ?

You will need to use an external python method.

I am currently writing one that will take any sql query and a file name as its parameters and put the results of the query into the
file as  comma or tab delimited records with or without the the field names in the first record.

Will post info here when I have it completed

Subject: [Zope] How do I download the results of a large Query


I would like to set up a link to some SQL query results in comma delimited
ascii that will download the data rather than display it.  I am having two
problems.  First the data is coming up in the browser and I want them to
download it without having to right click and select download.  Second,
before the SQL is completed the browser times out.

I think if I solve the first problem,  the second will be Ok,  Any ideas?

Subject: [Zope] ODBC and MS SQLServer Problems
Message-ID: <20000330163600.A3429@24.64.237.96.ab.wave.home.com>

I am trying to get Zope to play nice with MS SQL Server.  They are both installed on the same Compaq Proliant server.  I can create my database, make it accessible through ODBC and then add a ODBC Connection in Zope by picking my ODBC connection from the list.  I can then use the connection just fine for SELECTs and UPDATEs for a little while (30 mins to an hour). However, eventually I get the following error:

Error Type: sql.error
Error Value: ('S0002', 208, "[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'users'.")

where 'users' is a table name.  Up until this point, it was accessing 'users' just fine, and I can still run queries on it from the SQL Query Analyzer app so I know the table is there.  My only option at this time seems to be to delete the whole database and create it again and recreate the tables.  This isn't acceptable if this system is to actually be used.

Can anyone who has gotten SQL Server and Zope working post explicit instructions.  Or better yet, let me know what is causing the above error.

Thanks.

Not a lot if Zope continues to use Python 1.[5, 6, 7].

<opinion type="personal">

People are making a bigger deal out of this than it needs to be.
I admire Guido for taking a stance and fixing the problems he
perceives in his language;  I've had to support "backwards
compatability" issues in a commercial interpretive language
before, and "It Sucks(TM)".

Here he is being honest, stating that there will be change, but
not knowing the extent, and people are carrying on like it will
be the end of Python as we know it (or to use an Australian term,
"carrying on like pork chops").  When Python 3000 comes out, it
will not render all the Python versions before it automagically
obsolete; people will still be free to use whatever version they
most feel comfortable with (heck, I came across a site the other
day still running 1.3, and quite happy with it - it runs their
_current_ applications fine).  If there is a large enough groundswell,
there is nothing stopping other people from maintaining the "1.7"
version, but I personally can't see that happening (unless Guido
goes mad and puts braces in to denote blocks :-).

It's an Open Source language - you actually have options.

One thing that is kinda amusing (to me, at least) - the fuss I'm seeing
about this is, in a way, a testament to just _how_ _good_ a job Guido's
done as Benevolent Dictator. I've been using python since v 0.9.mumble,
and there's been _very_ _very_ few times where I've had to go back and
change working code because of a python upgrade.

And that's not just the python scripts, I'm also talking about C
extensions. 

Thinking back to a previous place of work where we had perl software of
around 10-12K lines of code, it seemed like every bloody minor rev of
perl5 would break something in it.

P3K has been talked about for a long long time as the "chance to fix
stuff" (ok, it used to be known as Python 2.0, but...).  I, for one, 
am looking forward to it. (particularly if the types/classes split 
goes away).

Here's a silly thing that's always niggled me : 

How do you get Zope to render the DTML that is 
stored in properties of a ZClass ? 

eg. Consider you have a ZClass with a string 
    property called 'my_property'

    In an instance of this ZClass, you set the 
    value of 'my_property' to "Hello <dtml-var x>"
    where x might be a string, integer, image etc

    Now, if a DTML method were to call <dtml-var my_property>,
    it would display "Hello <dtml-var x>"
    How can we get the DTML to be executed too, so that it
    displays "Hello [value of x]". Is there any easy method
    other than splitting this up into different fields ? 

Apologies if this is such a trivial thing. It's
escaped me for ages.

Heh, I just ran into this same problem a few days ago.  For some reason
PIL doesn't install a __init__.py (or at least the RPM of it didn't). 
Check /usr/lib/python1.5/site-packages/PIL for a __init__.py.  If it
isn't there, then make one with this content:

import Image, ImageFile, ImageEnhance, ImageDraw, _imaging,
GifImagePlugin, JpegImagePlugin, PngImagePlugin, BmpImagePlugin

if you are starting zope as root, the following (from the Zope root
folder) should work:

chown nobody access
chown -R nobody var

then you can start.  If you're starting zope as some other user, then
replace "nobody" with other user.  All the files in var need to be owned
by nobody or the starting user.  Copying Z2.pid won't work, because zope
sets it afresh each time it runs.

No, unfortunately, it's not possible.  You can use the Sybase database
adapter to talk to SQL Server 6.5 from Linux.  SQL Server 7 evidently
has a different wire protocol which prevents it from working against the
Sybase DA.  There is no ODBC support for Linux in Zope, and though there
have been rumblings about getting such a thing going one way or another,
nothing concrete has happened.

Not entirely true. You won't be able to use some SQL Server 7 features if
you use the Sybase adaptor, but the standard stuff should work fine.

Once freetds is thread safe, it should also be useful.

It is very possible to get ODBC connectivity using the OpenLink UDBC Multi-Tier
drivers and ZODBCDA. You will have to do some minor hacking, and if you want 
access to any fields longer than 128 bytes, some larger hacking :-)
(There is I think a major bug in SQLGetString in sql.c too that causes
Zope to crash -- I think I have fixed it... at least w.r.t. the UDBC drivers,
sz should be SDWORD [for OpenLink drivers anyway]).

The UDBC drivers are thread-safe (so they say).

I have a FreeBSD box quite happily talking to MS-SQL-7, I implemented this
for a client, so I can tell you how to do it, but, not what I did to get it to
work.The joys of contract programming.

I seem get restarts often when going into the management screen on one
of my servers.
All is dandy until I go to the management screen, then I wait a couple
seconds while it restarts.

Sounds like you are really after the LoginManager, which according to
reports is usable for non-PTK, but not for PTK.

It comes with the PTK, but is a seperate product in development.

Thanks for the answer, I'll have a look. But I would like the basic
structures to be compatible with the PTK, as I might want to employ that
later on. Any comments?

where qry_name is the *name* of the ZSQL-Method that I want to use. Thus if

Message-ID: <00033114332105.02681@tokey.kedai.com.my>

hi all,
i'm thinking of hacking zdiscussion to use rdb as the backend instead of zodb. 
but before i start anything, i'd like input from you learned zopistas.

me:- i'm not a REAL programmer.  just a hobbyist.  some of my concerns
-will a level  2 da be sufficient for high write site?  i'm thinking of using
postgres
-if i were to retain  what zdiscssion has, willl it suffice to have just one
table?  i would like to tie this to AUTHENTICATED_USER.  so i want to use user
db as the authenticating agent.  is it advisable to just put the forum table in
the user db database?  
-how would you guys do the tree from sql?
-what other improvement can be included?  what pitfalls to avoid?
-anybody done this(zdiscussion/confera with sql backend) yet?

this is just a start.  i'm not sure whether i'll succeed.  but i'll die trying
:)

thanks.

Yes, that's because the split does something else. 
Don't know if you want to pursue this further, but if so, let's try and
track it down

How do you call it from dtml?
Have you tried it from outside the ZClass (in a test situation)?

If there is a traceback, it will show in the same way as normally, I
believe.

Hi,
OK, part of my zope pages are inserted from another site (like frames,

What must make my product is taking these external pages, treating the
HTML code and print it with some new features.
When the user clicks a link of this inserted page, I want to intercept
the request, treat the URL to go and searsh the HTML code to insert it
in my page.
Is it possible to do it???
How???

Thank you for your attention.

Is there any possibility to get some debbugging information to know

Is there any possibility to see from within python if the smbvalid

Is there any way to calculate a roles effective rights on a object in Zope?
I currently have the situation that I can access two DTML documents

Trying to track the problem down, but I dont get it right.

What about this acquire permission settings checkbox?
Is there any special behavior when I added a local role in a

Can this affect acquisition of permissions of e.g. the anonymous role?

Ah, so I understand that it's not called with arguments. So you need
another external method.
Change you external method to look like this

def recursiveMethod(obj, result):
     if hasattr(obj, 'aq_parent'):
          result.append(obj.title)
          recursiveMethod(obj.aq_parent, result)
     return result


def ParentList(self):
    obj=self
    return recursiveMethod(obj, [])

Then make you external method refer to ParentList
This works without arguments from a testfolder. It should work from a
ZClass as well, but I did not test that.

Facile !... (façon de parler...) Deux solutions ŕ deux problčmes différents :

1- Pour rediriger une page vers une autre, utiliser la syntaxe suivante :
<dtml-call "REQUEST.redirect (<url>)">
Dans ce cas, on n'a pas accčs au contenu html de la page.

2 - Pour avoir accčs au contenu HTML d'une page extérieure au site, il faut
utiliser la méthode externe suivante (trouvée dans un HowTo du site Zope, que
je sois pardonné pour l'emprunt sans mention de l'auteur....) :
import httplib

def GetURL(site, filename):
 from httplib import HTTP
 http = HTTP(site)
 http.putrequest('GET', filename)
 http.putheader('Accept', 'text/html')  # we can handle text/html
 http.putheader('Accept', 'text/plain')  # we can handle text/plain
 http.endheaders()
 httpcode, httpmsg, headers = http.getreply()  # get response headers
 if httpcode != 200:
  raise "Could not get document"  # HTTP error
 doc = http.getfile()
 data = doc.read()  # read file
 doc.close()
 return data

Ensuite, aprčs avoir inséré l'External Method dans la hierarchie de Zope, pour
récupérer le texte html d'une URL distante, utiliser la syntaxe suivante :
<dtml-let mapage="GetURL ('www.toto.com', '/index.html')">

    //    Traitements...

</dtml-let>


3- Pour accéder au contenu d'une page interne au site, utiliser une référence
du style :
<dtml-let mapage="_['page_a_traiter']">

</dtml-let>


Et voilŕ !...

This becomes very funny, it doesn't work. It still returns nothing.
Although I found a way to get this working, I would really like to know the
cause why it doesn't work. I'll try something different right away.

Hi Rik,

Forget my previous message, I got it working now with hasattr. I made a

Message-ID: <000901bf9afc$bc8da9e0$0200a8c0@digitalview.com.hk>

I'm trying to assign the string:

1=1

to the variable criteria using this construct:

<dtml-let criteria='1=1'>

but I can't because Zope complains:

invalid parameter: "=1'", for tag <dtml-let criteria='1=1'>, on line 5 of
Create_List

Some playing around reveals that it doesn't like spaces and the equals sign
(=) in the string.

Am I correct in thinking that something delimited by single quotes (eg.
'this is a string') is a string? If so why can't I (or how can I) include
spaces and the equal sign inside the string.


thanks

Hi

Try <dtml-let criteria="'1=1'">

The bit inside the double quotes is evaluated as a python expression, and
thus returns the string you want.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.10.html

Unlike other tags, the dtml-let tag is quote-sensitive, requiring that
attribute values are quoted. So in the above code, you're trying to
evaluate the expression "1=1", which isn't valid Python code (you're
trying to assign a value to a value). What you want is:

	<dtml-let criteria="'1=1'">

the roles given to the user in the sub-folder *replace* the roles
defined in higher folders, due to the way user folders work. the user in
the subfolder must have the same role as in higher folders (so he can
traverse the higher folders), plus any new roles in the subfolder.

jcNTUserFolder was developped because htrd's NT User Folder has not this
functionality, which I needed also.

Thanks.

After scouring through all the docs that I can lay my hands on I finally
found an implicit reference to the above usage of dtml-let in "HowTo:
Advanced DTML techniques".

<dtml-gripe>
One of the main stumbling blocks in getting to grips
with Zope is the incoherent documentation. The information
one needs is scattered about in countless docs so a lot of
the time will be spent searching those docs. This isn't helped
by the fact that the guides and how-to's themselves contain many
errors in the examples.
</dtml-gripe>

But many thanks to the kind people on this list who have responded swiftly
to my questions.

<dtml-let criteria=="'1=1'"> should work.

In dtml-let, you write one pair of quotes to specify that your're writing a
python expression. Inside quotes you're writing python.

Examples of valid python expressions:
   'this is a string'
   23
   methodname

You can wrap up any of the above inside a pair of double quotes and then use it
in <dtml-let>

DTML-LET sintax:<dtml-let variable="exp"> </dtml-let>

So use:
<dtml-let criteria="'1=1'">
not
<dtml-let criteria='1=1'>

Or te best way ( I've  found it yesterday) :

<dtml-let valueVar="'var has value: %s'  % (var)">


All the best!

Thanks for the tip with the Zope Quick Reference! It helps a lot.
In my specific case however, I still have a problem. It may be caused by
permission settings, but I don' really think so.

I have a folder "sample_images" in the ZClass "foo".

I in the "foo_add" method I try:

<dtml-call "manage_clone(sample_images,'my_images')">

in the "with"-section. Things like "manage_addFolder" work there.

The result is:
"The object sample_images does not support this operation. "

Suggestions?

Thanks! Joachim.

Take a look and let me know if this is what you were looking to build.

I will add that I too am not a "real" programmer and while I have 
been using Zope for months I am still just ramping up.

Windows 2000 professional is the equivalent of NT Workstation.
on Windows 2000 server, there is two way of managing the domain: the old
way (with pdc/bdc,etc.), and the new way, with active directory. in
native mode, pdc/bdc support is disabled and my code rely on it. you may
not be concerned by this 'problem' because nt 2000 pro (aka workstation)
can't manage a domain.

bizarre, it should work. are you sure that Benutzers can *view* sub
folders? where did you create the administrator role? in the top level
folder or in the sub folders?
by the way, where do your users authenticate from? from the nt 2k pro
box (that is, the users are created *on* this box)? from a different
domain (and the domain controller is another machine)? until I can write
a better doc, also read in the zope archives the messages from 'Ava' and
'minf7'

I'm not at the office right now, so I can't do further tests. but I
should be able to reply on monday, at least.

by the way, if you want to force all users to log in, you may consider
using zope with iis, and let iis do the authentication. this may not be
possible with nt 2k *pro* (it doesn't work with nt workstation because
IIS requires nt server).

You should try, instead :
<dtml-let criteria="'1=1'">

A string is an expression, and expressions must be enclosed in double-quotes...

If you really want all content served out of mysite, you might want to
look into the SiteAccess product.

If you want just http://localhost:8080/mysite, try BASE1.

BASEn starts from the root and adds an object (from the current
aquisition path) according to n- BASE0 = root, BASE5 = root + 5 objects. 
BASE == BASE0

URLn counts the other way, starting with the current aquisition path and
removing an object according to n- URL0 = current path, URL1 current
path - 1 object. 
URL == URL0

The Zope Quick Reference has this information.

Message-ID: <38E4A089.9533A493@rrsg.ee.uct.ac.za>

Hi,
Say I want to call a dtml method that requires some extra variable, one
way is to set that variable in the REQUEST using REQUEST.set('name',
'value'), and one is able to call the dtml method.
Somebody suggested using the DTML-let tag to do the same thing, but I
haven't been able to get it to work:

<dtml-let variable="some expresion">
 <dtml-var dtmlmethodname>
</dtml-let>

when dtmlmethodname tries to access "variable" with <dtml-var variable>,
zope complains that variable does not exist. Is there a way of using the
let tag to accomplish this, or is there a different way?
Is using the REQUEST object the normal way of "passing" variables to
other methods ?
thanks
Allen

Perhaps something very stupid I'm doing, but I've a strange result here.


I've a ZClass which has the properties 'Title', 'Issue', 'Comment'.
This ZClass automatically reindexes itself in catalog.

Now, when I change the contents of Issue, Comment and then search the
catalog for the specific ZClasses, I get all the created ZClass instances.

However, when I change the contents of the Title and I again search the
catalog for these ZClasses, I get all but the changed instance back!
However, looking inside the catalog, the ZClass is still there!

I forgot even to mention one thing!

Only when Title is empty it is returned by the catalog! Otherwise it's
excluded from the catalog result list.

Tom.

---

Perhaps something very stupid I'm doing, but I've a strange result here.


I've a ZClass which has the properties 'Title', 'Issue', 'Comment'.
This ZClass automatically reindexes itself in catalog.

Now, when I change the contents of Issue, Comment and then search the
catalog for the specific ZClasses, I get all the created ZClass instances.

However, when I change the contents of the Title and I again search the
catalog for these ZClasses, I get all but the changed instance back!
However, looking inside the catalog, the ZClass is still there!

Is this a naming conflict? Or is it something else?

The editonly properties howto involved some python code were too complex for

If I just use the manage method, it will re-direct me to the manage screen

Subject: [Zope] Variable as record type or dictionary
Message-ID: <NBBBINPMKCEPBDEGNIEOCEBIDBAA.jcoruna@umd.es>

Hi Zopists!

I need to copy a record from into a <dtml-in> tag to use it later.

Suppose:

"Client" is a select ZSQL method (select * from Client where <dtml-sqltest
client_num type=string>).
----
<dtml-in "Client(client_num='2345')">
  copy the retrieved record in a variable
</dtml-in>
----
"OrderLine" is a insert ZSQL method:

insert into OrderLine
  (order_num,client_num,client_name,client_address,...,product_num,...)
values
  (<dtml-sqlvar order_num type=string>,
   insert the column "client_num" from the previous retrieved Client record,
   insert the column "client_name" from the previous retrieved Client
record,
   insert the column "client_address" from the previous retrieved Client
record,
   ...,
   <dtml-sqlvar product_num type=string>,
   ...)
----
Registering the order lines...
<dtml-call "OrderLine(order_num='OR4567',product_num='PENCIL-0067')">
<dtml-call "OrderLine(order_num='OR4568',product_num='PEN-BLUE-8')">
<dtml-call "OrderLine(order_num='OR4569',product_num='PENCIL-0045')">
<dtml-call "OrderLine(order_num='OR4570',product_num='PENCIL-0023')">
<dtml-call "OrderLine(order_num='OR4571',product_num='PEN-BLCK-1')">
<dtml-call "OrderLine(order_num='OR4572',product_num='PEN-031')">

----

Take in mind that I can't put the ZSQL method "Client" inside the ZSQL
method "OrderLine" because the Client method needs about 10 seconds to
execute and if every "OrderLine" method needs his time plus 10 seconds (from
the "Client" method) this can take over one minute for the above example
order. This is not viable! Awaiting 15 seconds to place the order is
acceptable but over one minute isn't.

The solution is to execute the "Client" method only one time. Any ideas how
can I copy the Client record?

Subject: [Zope] DST Zone Date, help needed!
Message-ID: <20000331145302.10067.qmail@hotmail.com>

Hello all,

I'm having a hard time with dates since portugal entered DST last March 26.

If I use:

<dtml-var "REQUEST.set('mydate','2000/03/31 15:00:00.000 GMT')">
manage_changeProperties(REQUEST)

I can get from "mydate" the utc hour (14:00) with the
fmt="a-la-C %H:%M" and the current GMT DST of Portugal(15:00) with
Zope's TimeMinutes().

If I use:

<form action="manage_changeProperties">
<input type="text:date" value="2000/03/31 15:00:00.000 GMT" name=mydate>
<input type=submit>
</form>

the fmt format and zope's zopetime() give me the same hour that
is the GMT-DST (15:00), i.e, somehow the "text:date" conversion is
ignoring the Portuguese GMT-DST and assume, in this example, 15:00 as
the UTC.

Since nobody is answering I'm going into the source to find where is this 
conversion. I'll get back with a solution... I hope :-)

Thanx,
Julio

Hi All.

and I have set the permissions exactly alike. Rendering the one class is
ok for non-super-users, but rendering the other one gives this:

It worked fine and give no special problem.

I have tried to update to the version 2.1.2 (RPMs) using Apache + pcgi.
Every time I try to use the zsql methods, zoe dies.

I have tried the latest version 2.1.6 (tgz). In this case I receive

Any suggestion ?

Can you not achieve the same thing with a single user folder in the

That's how I use NTUserFolder.

If you are fiddling with the setup of your pages you should do this

I briefly looked at the list's archive but did not find the actual answer.

2- Is there a way to purge the ZODB object history (ie. not the cache but the

The short answer is yes.

But your performance varies depending on how deep you want
to get into the subject. The most simple way to run Perl
CGI is:

(1) Use a Python external method to handle all CGI request.
    Let's call it "cgi_bin".

(2) Your CGI URL requests would be something like:
    http://www.mysite.com/cgi_bin?cgi=mycgi.pl&arg1=var2&arg2=var2

(3) Inside your external method, you check the values of
    REQUEST.cgi, REQUEST.arg1, REQUEST.arg2 and use Python
    pipe commands to launch the Perl interpreters and capture
    the output. (On Windows, use functions from the win32pipe
    module in Python's Win32 extensions.)

There was some discussion on all this about a week ago. Please
read the thread "newbie CGI question":

http://www.egroups.com/group/zope/showthread.html?start=26666

If you don't like the look of the URL, you can still use
Zope's SiteAccess product to tweak and interprete a URL like
htpp://www.mysite.com/cgi-bin/mycgi.pl?arg1=var1&arg2=var2

But in order to achieve decent response time, you will have to use
Apache + mod_rewrite + mod_perl + Zope. Which is more involved.

Hi again,

after read the mail I thought it could be misunderstood.

What DateTime returns wrong is the "GMT" part of, for instance,
"2000/03/31 18:08:58.3851 GMT".

It should return, "2000/03/31 18:08:58.3851 GMT+1".

Note: the hour is correct, but the gmt part no, should be added "+1".

Onderwerp: [Zope] Only allowing authenticated users to view document


I have a dtml-document which I wish to be viewed only by (certain)
authenticated
users.  I tried un-checking all the security permissions and the acquire
permissions boxes, but I can still access the method.
[cb] I guess you have the permission to view the rendered document as
manager
 Putting a
<dtml-var AUTHENTICATED_USER> in the form shows nothing when I test it (and
not
anonymous as I thought it would).

AUTHENTICATED_USER is an object , the html source of  your rendered document
will show its id
try: "AUTHENTICATED_USER.getUserName()" (with quotes) in your dtml-var tag,
which is a string representing the name of the authenticated user (or
'anonymous').

cb

El castellano tambien funciona aqui. ;) Podrias dar mas
detalles del mensaje de error? Asegurate de que el
duenno de las carpetas sea "nobody", para que no haya
problemas durante el proceso de makefile.

Could you provide the error message itself? Make sure that
the owner of folders are "nobody". (Usually I am lazy
and change myself to superuser, and then change everything
recursively into nobody.nobody for owner.group)

The owner:group of all folders is nobody.

The system is: 

	RedHat 6.1
	ZOPE 2.1.6
	Python 1.5 

i don't know what more tell you about the error.

We too have seen more frequent restarts centered around /manage
activity.  I have one user that I can tell when he starts working in the
morning by the first Zope restart of the day.  We have not been able to
get a consistent repeat of the behavior though.

We have three servers running with one taking most /manage activity and
that machine is the one that restarts the most.

>i don't know what more tell you about the error.

In case you have not realized, what you have provided is NOT
an error message. I don't know why you call it an error message.
That is why I asked you to provide the error message. :)
If you have an error message, please provide it. If not,
please don't call something an error message when it is NOT.

Por Dios, si no hay error, para que me asustas? :)

Please read the README.txt file and follow the steps there.

(1) First check your environmental variable is properly
    pointed. Do

    echo $SYBASE

    if it does not show the directory of installation of your
    Sybase database, you are in bad shape. You need to set this
    environment variable, preferable from the moment you reboot
    the machine, but if not, from your Zope's "start" file.

          SYBASE=/mnt/sybase1192
          export SYBASE

(2) Follow the instructions in README.txt

    cp Setup.linux Setup
    make -f Makefile.pre.in boot
    make
    cp sy_occ.so ..

Then it'll work.

(Me parece que tu problema no es Sybase adapter, tu
problema puede ser Unix/Linux. Parece que no eres
familiar con Unix/Linux.)

All,

Has anyone used Andrew Kuchling's Oedipus package (parses and displays
ODP data from dmoz.org) with Zope ?
In the Oedipus 0.0.7 distribution there is a .gz file with what looks
like a Zope product distribution.
But unpacking it in the usual place for zope products doesn't make it
visible in my Zope Products folder.
I am using Linux RH 6.1, Zope v 2.1.6, Oedipus v 0.07.
Any known problems ?  Do I need to have XMLDocument imported before
Oedipus will import ?

Help !

Hi,

How do I store an object in RAM during Zope's up-time?

I don't want to store it as a persistent object.
And I don't want it to disappear after a http transaction
(so REQUEST variable is no good.)

I would like to be able to create this object given
a particular http transaction, and afterward I may
want to modify it. This is a bit like session management
data, but it's a piece of data that is shared by all
sessions...

regards,

Hung Jung

None other than to check the Zope-ptk archives for info, I haven't used
it yet myself.

As far as I know there is not currently any such mechanism.  I wonder
if the PTK people have thought about this?  I haven't gotten around
to signing on to the PTK list yet, but I really need to.

Go to database management on the control panel, and compress your
database.  This will delete old transactions up to whatever point
you tell it, thus shrinking the database.  It won't have any affect
on rendering speed, though; from what I understand ZODB is designed
to keep read performance high regardless of the number of transactions
recorded in the database.

I read you could define a ZClass instance's method as a field-index of a
ZCatalog; but it's not working for me.

The DTML method dept_code is simply:

  <dtml-return "_.string.split(jobcode,'-')[0]">

When I call the method directly it returns a single character, the first
character of the jobcode.

The method dept_code is defined as a field-index of the ZCatalog JobsCat.
But when I access JobsCat thus:

 <dtml-in "JobsCat(meta_type='Job Opening', sort_on='dept_code')">
   <li>
   <a href="<dtml-var "JobsCat.getpath(data_record_id_)">">
            (<dtml-var dept_code>) <dtml-var jobcode>: <dtml-var title></a>
 </dtml-in>

the items are not sorted, and dept_code is null.

Can anyone see what I'm doing wrong?

Hi Tino

A lot of my pages are served by sqlsession, and sometimes I have to do
maintenance on the sql tables, and take down the database server.

Hmm, here is what I have, in DTML Method aaabbbccc::

 <dtml-var standard_html_header>

 <p> Calling asdf with variable 'foo' = 'bar', using the let tag: </p>

 <dtml-let foo="'bar'">
   <dtml-var asdf>
 </dtml-let>

 <dtml-var standard_html_footer>

And in DTML Method asdf::

  <p> <dtml-var foo></p>

When I view aaabbbccc, I see::

 Calling asdf with variable 'foo' = 'bar', using the let tag: 

 bar

which is exactly what I expected.

Can you see any differences between your code and mine?

Subject: [Zope] REQUEST weirdness . . .
Message-ID: <38E534D6.133329E4@globalcrossing.com>

'ello.

Bear with me on this one; I'm having worlds of problems coming up
with any kind of coherent way of expressing the problem. :)

I have a form which contains the following:

<input type=text name="street.address1:record">
<input type=text name="street.address2:record">
<input type=text name="street.city:record">
<input type=text name="street.state:record">
<input type=text name="street.zip:record">

To parse this data, I would ordinarily just use a dtml-with:

<dtml-with street>
  <dtml-var address1>, etc, etc, etc
</dtml-with>

No problem.  This, however, is where things get interesting.
I'm passing the data from this form to a "confirmation"
page.  The data from the first form will be simply put into a bunch
of "hidden" fields, where the user will be prompted to REALLY do what
they were doing, or cancel back to the original form.

Now, I don't want to have to re-code the confirmation page every
time I add a new value to the main form, or remove an input for
whatever reason.  What I figured I would do is the following:

<dtml-in "REQUEST.form.keys()">
  <input type=hidden
         name="<dtml-var sequence-item>"
         value="<dtml-var "REQUEST.form[_['sequence-item']]">">
</dtml-in>

This works fine for all the values in the form which aren't using
the ":record" tag, but obviously for my address, I'll 
need to iterate through it.  ie:

<dtml-in "REQUEST.form['street'].keys()">
  <input type=hidden
         name="street.<dtml-var sequence-item>:record"
         value="<dtml-var "REQUEST.form['street'][_['sequence-item']]">">
</dtml-in>

( In the original code, "street" wasn't hardcoded, and I just wrapped
  that statement around a dtml-try, where the except clause was my
  original dtml-in. )

This code doesn't work.  Upon closer inspection, the following line
was the culprit:

  <dtml-in "REQUEST.form['street'].keys()">

Upon even closer inspection, *none* of the dictionary functions would
work.  Not even <dtml-var "REQUEST.form['street']['address1']">

Then I decided it was time to just see exactly what was in the object.
<dtml-var "REQUEST.form['street']"> yielded the following results
(I had just entered sequential numbers for all five inputs):

address1: 1, address2: 2, city: 3, state: 4, zip: 5

Here's the output of <dtml-var "REQUEST.form">:

{'street': address1: 1, address2: 2, city: 3, state: 4, zip: 5, 'submit':
'submit'}

The original <dtml-with> code still works, as does
<dtml-var "street.address1">.  I've also tried using getitem:

<dtml-var "_.getitem('street')['address1']">

I'm quite confused.  It would appear that "street" really *isn't*
a dictionary at all, yet somehow the <dtml-xxx> tags still work.  What's
going on here?  I'm quite befuddled.

Thanks a lot in advance for any help, and apologies again for the
convoluted message.

Message-ID: <Z4C$7kAIdS54EwQ+@compkarori.com>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Hi,

I previously posted that I was having problems with Zope and Interbase
losing the ODBC connection ( on Win32 ).  This would happen whenever I
entered the web management interface, and at other times when I could
not identify a cause.  I then had to shut Zope down and restart it.
Zope would not allow the ODBC connection to be made otherwise.

I was using the much older Visigenic driver because the Intersolv driver
truncated varchar fields (a known bug).

However, recently I joined the Interbase mailing list, and one of the
Interbase staffers suggested I retry the Intersolv driver and recast the
varchar field as char to work round the truncation

viz. select cast(myvarchar as char(n)) as myvarchar from foo;

I am pleased to report that this works well, and over the last few days
I have not observed a single disconnection.

Furthermore, I have noticed that the very first use of the OBDC
connection after Zope started always gave an error.  This problem has
also now disappeared.

For interest, my experimental server is using a PII 300 overclocked to
450, 128Mb ram, NT4 server, and an IDE hard drive served on an ADSL
connection.  There are about 20,000 items in the ecommerce database.  I
am also using Interbase to do Zope session management.

You can reach the server by using the url below ( a PHP script on my
static server redirects to the ADSL box).

I'll post an update if the situation changes.

In addition, Interbase Corp has expressed an interest in supporting Zope
by helping/writing native drivers for Linux and other platforms which
are supported by the new Open Source Interbase 6.0

I know that in the CVS now, record objects support the Python mapping
interface (which is what you're trying to do) but before that, and I
think this is the case for the 2.1.x branch, this wasn't supported, and
you needed to access the object by attribute only.  This makes what you
want to do in DTML pretty impossible (but not impossible from python).

I guess you can try waiting for the next main trunk release, or you can
modify your record objects to support a mapping interface just like the
CVS does.  It's a very simple class in the
lib/python/ZPublisher/HTTPRequest.py module.  This is probably the
simplest solution to your problem.

Nope.  In your case it's an object with _instance attributes_ that
contain your values.

Hi there,

For some reason Zope would suddenly hang and it's thread would consume 99.9% of CPU usage.  The first time this happened the problem magically disappeared after a complete reinstall. Here's what happened while casually throwing bannerexchange code into the default DTML document.

standard_html_footer

   </tr>
  </table>
  <dtml-var bannerexchange>
  </body>
 </html>

bannerexchange

 <h2><dtml-var title_or_id></h2>
 <p>
 <!-- bannerexchange code -->

I'm on Zope 2.1.6, do future version prevent me from making accidental infinite loops like this?

Message-ID: <38BC6ED7.94F2BCBC@aHIT.de>

Hi,

I created a POIDocumentClass (ZClass based on DTML Document; meta type
PIO Document) .
Than I created an instance of this POIDocumentClass id 'MyDoc' title 'My
Document'.

Now when I try to find all POIDocumentClass instances in a Folder I do
the following:

<dtml-with aq_parent>
<!--#in "objectItems(['POI Document','DTML Document'])"-->
  <!--#if
"AUTHENTICATED_USER.has_permission('View',_.getitem('id',1))"-->
      <a href="<!--#var "absolute_url()"-->"><!--#var title--></a><BR>
   <!--#/if-->
<!--#/in-->
</dtml-with> 

I get back the right title 'My Document' but absolute_url() returns
http://myserver:8080/foo/%3cstring%3e instead of
http://myserver:8080/foo/MyDoc

When I create a DTML Document instance within the same Folder
absolute_url() works fine.
I suspect there is something wrong with my POIDocumentClass :-(
Can anybody please explain this behaviour ?

I created a ZClass based upon DTMLDocument.I wanted to have

So I decided NOT to derive my class from ObjectManager.
 
Now when I create an instance of my new class within a Folder 
the instance has no id !

I think this is not a feature ;-)

Okay.  Perhaps someone else on the list can answer this one then: I
have a standard Debian install of Zope.  ZServer works fine.  Apache
works fine.  Zope shows up fine in apache.  Except... I can't log in. 
At all.  With any username.  What do I have to do to get Apache to
recognize Zope's authentication?

Don't forget that you can also download Zope and try it out easily. I'm
running it on Win32 for some development tasks, and it did not take much
effort at all to install it and run it locally. So, if you want to continue
playing you can always do that.

In terms of popularity and being supported for a long time, I do believe
that DC has been quite successful in their consulting business, so they'll
be around. And, Zope itself is open source, so there will always be avenues
available for using it.

IMHO, you'll be quite happy wiht what you can do when you migrate those apps
to Zope. In the meantime, though, you can continue using them by setting up
Apache with rewrite rules that allow you to access those CGIs still. Without
knowing anything about your app, it's difficult to state how you would
"interface" with them. There are avenues for doing so. A pretty
straightforward one might be XML-RPC. (Your perl CGIs could access Zope data
via XML-RPC.)

I think Zope is pretty stable (and I think most regular users of it would
agree). It's not generally more likely to die than your system itself. If
you do "low-level" development on a different machine, your database should
be OK. Plus, all you need to do is back up your Data.fs file. If something
got really messed up, you just drop in the back up file.

I think the answer to "what if Zope goes down" is really the same kind of
thing as "what if the server goes down?" or "what if the drive crashes?"

If you really want, there is a Zope product that will mirror your site in
HTML (and others have used wget to mirror the site in HTML). But, I think
it's better to just maintain a solid Zope, because your site quickly goes
from being a static HTML thing to being a dynamically produced, interactive
thing which can't be reasonably represented by HTML.

People on this list have done benchmarks using ab and other tools. I think
the general consensus was that with a moderate machine and a moderately
dynamic app you can do a million hits+ per day. Through more machine at it,
or go for ZEO (which lets you mirror the object database on multiple
machines) and you can handle lots and lots of traffic.

Our site (Byproducts.com) has been running on Zope since last May. I've had
very little downtime and I don't think I would blame any of it on Zope.

Still much to learn.

I'm trying to write code to display a tree where different
kinds of node require different display action.  Each node has a
property (possibly acquired) "kind".  For nodes which reach
the innermost <dtml-else> in the code below I want the dtml
content rendered.  How can I do this?  If i refer in
some way to PARENTS[0] then id goes up with it.

Please, please, please, what expression will work here
to get the content of "id" rendered?

Code follows
------------
<dtml-tree expr="lists" branches=objectValues sort=order>

        <dtml-if "meta_type=='Folder'">
            <dtml-var title_or_id>
        <dtml-else>
            <dtml-if "kind=='discussion'">          
                    <A HREF="<dtml-var listURL>">

Just to follow up to myself so you know: I have seen snippets about
RewriteRules all over the place for using Apache with Zope...

I have tried everything i've found, and nothing has worked so far. 
(The RewriteRules appear to do nothing at all...)

Lot's not there. The only ones that show are those that use Zope built-in
ZServer. If your Zope is hidden behind a different web server and that
webserver's ID string hasn't been changed to mention Zope, then your site
doesn't show. Anyway none of my sites show up on the Netcraft list.

This is from the "Other Uses" page, right?  In that example, it is an error
to access the folder, since it is only meant to act as a placeholder for a
session value.  The IndexError occurs when the code tries to access the last
element in the remaining path, but there *is* no remaining path!

Access Rules execute before any authentication takes place, so
AUTHENTICATED_USER doesn't exist yet.  This also prevents them from
accessing any other Zope objects unless you give the Rule a Proxy role.

It looks like you need GenericUserFolder or UserDB.

Message-ID: <010401bf831d$2f850440$6e00a8c0@redindustries.com>

(short time reader, first time poster)

So I've set up my zope installation to test it out for use as the intranet
server and content management system for my company. One of the features
that I intend to use heavily is the FTP access, the main users of the system
will be designers and their clients, so I want to set up an interface that
works with existing tools <DTML-rah-rah yeah>.

However everytime I connect with ftp (used Dreamweaver's FTP client as well
as EMACS) I get an "PROBLEM(100) ZServer unhandled connect event" error from
Zope. I've just upgraded to 2.1.4 which solved the crashing problem for the
most part.

My question is what is an "unhandled connect event", can I make a connect
event be handled? Is there a howto, a document or a previous thread on this
subject?

Help, I want to be a fanatic!

Right.

Yes.  One thread will win, and one thread will loose.  The winner will
get the new id.  The looser will try again.  The looser will find out
when it tries again the the id it wants is taken, and will report that
to the user.  The user picks another id.

No, but a programatic resolution protocol is planned for future releases
of ZODB.

The chances of colision are very small unless you have an incredibly
write intensive application (which is not ideal for ZODB filestorage. 
In that case, you should store your information in a RDBMS).  This the
"optimism" in optimistic.

WU IMAP on a RH 6.x box is *bizarre*.,

Ok, I kicked this off before dinner, having added some debugging output to
imaplib.py.  When I came back, there was a TON of it dumped across the console
at which I was running Zope, but no mail.  Basically, it had walked down through
all the .gnome/* directories, sucking up bitmaps, retular files, subdirectories,
everything (ICK!).

Maybe we need to add a property to the WorldPilot object which lets you
configure the folder passed to the initial list() call (e.g., to be something
like "~/Mail").  This parameter would default to the empty string, so that the
Cyrus clients would continue to operate as before.  I'll see if I can't come up
with some kind of patch.

My sarcasm meter is in the shop after an accidental exposure to
comp.lang.perl.misc (ugly story, don't ask), so I'm not sure how big a brick of
salt to apply.  WU IMAP is a nice stick for clobbering those who think Zope's
documentation stinks;  there is absolutely *nothing* in the package to give the
hapluse admin any clue how to configure the damn thing.

I spent about 4 hours this weekend prowling the net looking to resolve this
issue.

Hi Tres,
This was written up last week and after a little digging on egroups (I thought I
had saved that message) I finally found it. Jo Meder provided the following
information

<quote>
Chances are, that the request to "LIST *" in directory "" that 
imaplib issues cause your imapd to begin scanning your whole home 
directory which can be a lot of data, as we all know.

I worked around this problem by creating /etc/c-client.cf with the
following contents (the first line is required by imapd, otherwise
the file is not accepted):

--------------------------------------cut here -------------------
I accept the risk for IMAP toolkit 4.1.
set black-box-directory /var/spool/imap_folderlinks/
--------------------------------------cut here -------------------

I then created /var/spool/imap_folderlinks and symlinked the
directory in which my mailbox folders reside to 
/var/spool/imap_folderlinks/jo

Repeat for all users on the system and set permissions appropriately.



        Jo.
</quote>

Also some information on this can be found in the file imaprc.txt that should
be in /usr/doc/ or where ever RH dumps it. (I'm running this on SuSE myself.) I
have tried this fix but I probably will.

Subject: [Zope] RE: Different Login Screens for Management and User?
Message-ID: <38BCA9A0.C5CEA34@cs.rutgers.edu>

I was working on the same kind of problem (see my earlier post today),
and I think
I found some solution, thanks to the many hints here and in the zope-ptk
list. It's
actually quite simple.

The trick is to play with exceptions. In your standard_html_header,
include something
like (replace 'Member' with the role you want):
<dtml-unless "AUTHENTICATED_USER.has_role('Member')">
   <dtml-raise type="Please Login!">
                <p>Please login before entering!<p>
   </dtml-raise>
</dtml-unless>

When the error is raised, the standard_error_message is called, so from
there,
you can do some more tests and go to the appropriate login page. I have
not
fully tested this yet, but I think it should work. I think if you put
type=Unauthorized in the dtml-raise tag, you should get the usual HTML
login instead of the error.

Anyone has a better (more elegant/original/creative) solution?

I get this exact same problem trying to add completely normal File Objects
to my Zope site.
I can create the object empty if I don't include an upload, but the instant 
I try and upload anything it dies with the above error.
It happens _constantly_ for me, not just time to time.

Thank you. This 'patch' did in fact work although the problem was in fact more
subtle than originally described - the 'unhandled' type error only
arose if I used joins in the select part of the statement.

Message-ID: <20000301011319.A10204@devware.com>

So, if I am grokking the whole zope thang properly here, then
theoretically, when I imbed objects within my zope documents, I
shouldn't hardcode in specific urls to them.  Instead, I should treat
them almost as if they are always in the current directory, even if
they are a couple of folders up.  This way, if I want to override some
behavior in the future, I just copy the object down into the current
folder and edit it.  I notice however, that if I do this, it plays
hell with browser caching because the browser winds up pulling things
from different places all the time even if it's actually winding up
pulling the same document down.  How do other people deal with this?

Hi Lucas,

I am the original author of zGold, and I'd like to explain where it came
from and what happened to it subsequently.

zGold was originally written as an exercise of learning and also as an
example site for a conference/exhibition here in the UK.

At creation time there was no intention of releasing it to the public at
large.  It was however made available purely as a 'teaching aid'.

Subsequently it was proved that there was a serious security hole in it that
allowed users to see the clear-text passwords/usernames of other users.

Also since this was created in my 'spare time', I have had no further time
to allocate to it and it has sort of died of neglect.

That being said, I still have the original tarball hanging around and anyone
who wants it can mail me and I'll get it sent out.

caveat:
zGold is not supported in anyway and is not 'production' ready.  Use it at
your own risk.  I will not be liable/responsible for any/all problems it may
cause.

Thanks for listening.

I want to import a static HTML web site (about 10 directories,

But I couln't find any documentation about it.

Ok, I found load_site.py
 ./load_site.py [options] url file .....    

 But:
 	Which 'url' should I pass here?
 	Does 'file' mean that I only can import one file an not a 
		whole directory tree?
 
Where can I find more information?

Thank you
Veikko

Howdy all.  Please note that "More" under "Zope News" has the old style
display.

Question: do you think we should have a knob available for members that
lets them toggle the home page between old style and new style?

Message-ID: <200003011127.VAA65638@mail.theinternet.com.au>

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

Hmm .. this sounds really weird. 

In my case I observed the following.

Structure:

/
  +Intermobil
    +daten (up-/download section with form for upload, dtml-methods,
external methods etc)
       +category1
       +category2
       +... (sub- and subsubfolders for storing the files)

testfile is a Winzip/Zip file (1.129 KB), uploading it gives the error.

I created a test folder somewhere else and pasted the content of the
daten folder (without category subfolders), tried to upload my zip file
there .. and -voila- it worked.

Then I changed the upload method in my test folder by inserting a
<dtml-with "Intermobil.daten"> in order to redirect the upload into a
category subfolder of the original daten folder .. and -surprisingly for
me- the upload of the test file worked, too.

I deleted the file, went back to daten, tried again and got the same
error as before.

So here I'm really confused, cause I don't know where to look and what
exactly could have caused this problem.

Thanks for bringing up this to the list again,
Thomas

Howdy all.  Please note that "More" under "Zope News" has the old style
display.

Question: do you think we should have a knob available for members that
lets them toggle the home page between old style and new style?

Message-ID: <38BD079B.3F5D35D5@imeme.net>

Zopistas,

I'm setting up zope on a linux box with support for large files.
(>2gb).  I need to make sure that the ZODB will continue to work
properly past this point.  Is the filesystem stuff the ZODB does handled
by python or ZODB?

If the answer is ZODB, where can I look for fs calls to make sure
they're 64 bit?

Thanks,

   It is an URL to a Zope folder. If, for example, you've installed Zope on
http://my.server/path/to/Zope/, and you want to upload your site into
http://my.server/path/to/Zope/virtual/site (the folder /virtual/site should
be created before using load_site.py), the URL will be just
http://my.server/path/to/Zope/virtual/site

   The file can be a file, or a directory, or a list of files and
directories...

Use the absolute_url() method on the objects. 

That way, your generated HTML will contain absolute URLs to the objects,
that are the same across different Folders in your site even when the
object is acquired from elsewhere. Overriding as you described will
still work the same, the URLs will reflect the change accordingly.

Syntax variations (as always from the top of my head, not tested, YMMV):

  <dtml-var "object.absolute_url()">
  <dtml-var object url>
  &dtml.url-object;

The last notation is especially useful in HTML tag attributes, as it
won't break WYSIWYG HTML editors:

  <a href="&dtml.url-object;">Go to object</a>

Brian,

I think it's a permissions thing with tinytable. There's a permission called
something like 'access tinytable contents' which you need to give to the
anonymous user in the squishdot folder.

Well, that's how I cracked it, anyway...

cheers,

Chris

Hello there,

we got a site up and running (its actually a shop solution based on
zope).
Platform is NT, zope version is 2.1.4.

Most of the time, the site is running very fast. But some times it
hangs.
It does not use much processor-time at this moment (arount 14%) but
it does not process any requests for some seconds.
Its very annoying. Does anyone know how to avoid such behavior?

thanks. I've imported the data now. 

with
python ./load_site.py -D  -u superuser:pwd http://host:8080/ directory

There are 2 problems now:

1) HTML character references are only imported within quotes.
The line 
	<a href="#Einf&uuml;hrung">Einf&uuml;hrung</a>
is imported as
	<A href="#Einf&uuml;hrung">Einfhrung</A>

and 
Transportmittel unerl&auml;&szlig;lich.
is imported as
Transportmittel unerllich.	


2) file names are used as the DTML document Id e.g. index.html
It seems to me, that index_html is the default DTML document within a
Zope directory.
Can or should I change it to index.html? And where?


Thanks
Veikko

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

What optimization do you have NT set for?

File Serving, Network processes, or local use?

By default NT optimization is set for file serving. This means that if some one is making heavy use of the file serving cpabilities
of the machine it gives less time to network processes like zope.

   Looks like a bug in HTML parsing. There is no simple solution for this.
When I got some free time (and it shouldn't be in the nearest future) I'll
add additional processing into the parser in load_site.py.

   You don't need to. Just create DTML Methtod index_html and put
<dtml-var index.html> in it. That's all.

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.

The how-to list is a bit daunting; also I get the feeling that
there's a level of jargon necessary just to figure out what 
documentation to read.  I don't have that, so I haven't found
what I'm looking for.

Is there anything like what I'm looking for?

But, on the other hand, there is not much file-serving at all from this
machine.
I only use it to transfer log-file or such.
All other communication is over Zope only.

It appears to me it could be some dead-lock situation inside Zope or
medusa.

Subject: [Zope] Best way to run Zope for hosting apps by multiple developers?
Message-ID: <000901bf8398$f3019ca0$24886883@uoguelph.ca>

Hi,

The University of Guelph is looking at making Zope hosting available
to our departments and organisations. Because we want to be able to
use MS Access databases, we propose to run Zope on NT (so that we can
use Z ODBC). In essence, we're looking at using Zope within an ISP
hosting model, where we will provide the infrastructure and our
clients will do their own development.

I'm trying understand how to design a Zope system to achieve two
things: 1, make it less likely that a poorly written app will
compromise the service for other developers, and 2, establish a test
environment where applications can be debugged, and then moved to a
production server.

I have two questions:

1.
I've read the FAQ for ISP's, and I've seen references in the
documentation to ways of configuring a system so that Zope so that
each client gets their own instance of Zope. This would presumably
help to insulate one Zope app from another. However, I can't find any
details about how that's done... can anyone point me to more info?

2.
Given developers with administrative control of their own folders on
two Zope servers (test and production), how can I make it possible for
them to take a test application (consisting of a set of Zope objects,
let's say within one Zope folder object), and move it to a production
Zope server. I can do this by exporting from one Zope server and
importing into another, but this involves giving the developers access
to the file system (they must place their exported object in the
"import" directory on the target Zope server), and all developers will
be dropping their objects in the same place. It's not elegant, and I
can foresee various management problems and security risks arising
from it. Are there other ways to migrate a Zope application from one
Zope server to another?

Thanks in advance for any pointers,

Nick Dobbing.

Hi:

I've been using DTML successfully to generate around 20+ reports outside
of zope itself.  The result come back from the DB as a pdf document.  The
solution has worked well.

It looks like there might possibly be a bug in the dtml totalling process,
however, when dealing with larger numbers.  The results on one report are
accurate for a 20 row table with smaller totals (say, e.g., 51518), but
the larger totals are incorrect (e.g., it reports a number say in the
300,000 range rather than 1,378,835).  The DTML for that column (the TOTAL
column) is: 

<!--#var total-TOTAL fmt="%15d"-->

Has anyone else seen this? The version of DTML I'm using is from the last
quarter or so of last year.  Any ideas?

All - Have a problem which I am certain many of you have already
encountered.

With most web servers, you can create specific web server instances that
listen to virtual network interfaces on the server (virtual IP addresses).
For example, I can have multiple httpd instances, with httpd1 listening to
192.168.1.101 and httpd2 listening to 192.168.1.102 on a box where the
physical IP address is 192.168.1.100.  This is configurable within the web
server.

I want to be able to have Zope listen to a specific network interface, i.e.
- a virtual IP address that has been created on the server.  This will allow
me to have multiple Zope sites running on the same machine.  How can this be
accomplished?  Any/all suggestions are greatly appreciated.

Thanks,
-Brian

You could run Zopes behind an Apache server and connect via ProxyPass or 
FastCGI. This would even allow virtual servers on one IP address.

I will be roasted -- I thought I'd followed these directions already, and still
had it hang.  When I went back to try again, I discovered that the symlinks were
screwy (how imapd found my home directory at all is a good question).  When I
clean them up, it works!

Hmmm, /usr/doc/imap-4.5 has only a README file, which doesn't mention the
/etc/c-client.cfg file at all (it talks about building the package, and setting
up the /etc/services and /etc/inetd.conf files to make IMAP work).  Thanks very
much for reposting those directions!

Message-ID: <200003011733.SAA13630@rztsun.rz.tu-harburg.de>

Am I the only one whose bobo_modification_time started today with
/2000/2/29 instead of /2000/03/01?

I create a new method Time_now:

<dtml-var ZopeTime><br>
<dtml-var bobobase_modification_time-->

and the Output is:

2000/03/01 18:30:21.091 GMT+1
2000/02/29 18:30:5.198 GMT+1 

Same appears in my Undo Log (February, 29th started again today) and so
on.

TIA,
Thomas

IMHO this is not necessary:

just use versions for your developpment work, then commit your version 
when it's done.

If you want to stick with Basic HTTP Authentication, the key is to persuade
Apache to pass that info through.  On my setup, this involves adding the
following to the "RewriteRule" line:

 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

Also, the "RewriteCond %{HTTP:Authorization} ^(.*)" line has to be repeated
before *each* rule to which you want it to apply.

Hi everyone,

I've grepped through the source and consulted the ZQR, but I still haven't
figured out how to use bobobase_modification_time. I've got a directory
with a file object, and I'd like index_html to display when that file
object was last modified. I've tried all manner of syntax combinations,
but I can't get it to refer to the modification time of a given object and
not just the modification time of index_html. Suggestions?

-Tim

Subject: [Zope] Dealing with Dictionaries
Message-ID: <4.2.2.20000301125741.00b6b100@saladin.aisys.com>

I have a DTML method from which I want to answer a dictionary.  It looks 
something like this:

<dtml-return "{'foo':'bar', 'biff':'boom'}">

I want to be able to use this information in two different ways.  First, I 
want to be able to get a list of keys from the dictionary.  Second, I want 
to be able to get a list of values.  I could easily do this in Python, but 
I'm sure there must be a simple way to do this in DTML.  I tried something 
like:

<dtml-return "_['dictionaryVariableName'].keys()">

but that didn't work.  I did notice that if I just used 
"_['dictionaryVariableName']" I actually got the keys.

Basically I'm trying to create a system by which a user can enter a full 
string and an abbreviation for the string.  I want to be able to produce a 
list of the full strings, and I want to be able to produce a list of the 
abbreviations.

Any help would be appreciated.

Thanks.

The ZODB uses a "pluggable" Storage-derived object to do the actual reads/writes
(this is where Ty Sarna's BSDDB Storage gets plugged in).  The "standard"
Storage is the FileStorage, defined in
$ZOPE_HOME/lib/python/ZODB/FileStorage.py.

   Frank, I agree, however I probably should have been more specific.  I
would like to be able to do this using ZServer rather than using Apache or
in my case Netscape Enterprise Server.  Do you know if ZServer supports
this?

Use the source. :)

From z2.py:

  -a ipaddress
    The IP address to listen on.  If this is an empty string
    (e.g. -a ''), then all addresses on the machine are used. The
    default is %(IP_ADDRESS)s.

so in your start script, add: -a xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is the IP address you want to hook to.

Cheers

Bill

1: What is your timezone setting. It could be that dates are displayed in a
different timezone.

2: If you do your test from a DTML Method, you'll be shown the modification
date of the container it is called on. For an explanation, see:

I think I found the problem, at least for my purposes. :)  I'm not sure
if this has already been corrected in the latest versions of DTML or not
but it might be worth a check.

DT_InSV.py line 239 was:
  s=item*item

Instead, I'm now using:
  if type(item)==type(1): s=item*long(item)
  else: s=item*item

Looks like this information is needed to calculate some of the other
statistics and when the item is a large integer it will cause an
exception.  The exception is then caught and results in that item
be omitted from some calculations, such as the total.

Hi Eric:

I'm not sure how much of what I've done would apply to your situation.
Basically, the powers that be wanted some complex reports for an Access
application hooked up to SQL Server.  Access reports were not anywhere
near flexible enough to produce the output they wanted.  Consequently,
I ended up building a reporting interface onto the rather low-level python
pdf module and then hooked it up to the DB.  That way I was able to
do most of the complex stuff in python, use DTML templates whenever
possible, and output the results in pdf.  When the user clicks on a report
in access, the application shells out without them knowing it and the
next thing they know a pdf pops out in Acrobat.

I gave some thought making it available to whoever might find it useful
but haven't had much time to make it more friendly.  In particular, I
might take the pdf wrapper, which allows for high level pdf
formatting (for switching font sizes, styles, page numbering, headings,
etc), and somehow hook it up to zope.  Sometime after I started,  someone
did come up with a pdf document hook for zope, but it didn't offer the
formatting options I needed and my reports weren't going through zope.  It
might be worth a look, however, for your purposes.

If you can get away with it, avoid PDF documents altogether and just use
DTML to web enable your reports through zope.  I ended up using pdf
because the users didn't want to web enable this stuff, wanted more
precision then browser formatting allowed, and I thought it would be kind
of neat to try....

Subject: [Zope] Advanced DTML Question
Message-ID: <4.2.2.20000301155145.00b6c400@saladin.aisys.com>

I'm trying to write a DTMLMethod which will write out a list of data items 
found from a catalog, sorted in alphabetical order.  This is 
easy.  Basically I do something like this:

<dtml-in "Catalog(meta_type='foo')" sort=someAttribute>
     <dtml-with "Catalog.getobject(data_record_id_)">
         <dtml-var objvar1><dtml-var objvar2> ...
     </dtml-with>
</dtml-in>

I've got this working, no problem.  Now, since the list of these items 
might be somewhat long, I want to build a simple index at the top of the 
page and use page anchors to get to key points on the page. Basically I'm 
going to display the alphabet and when the user clicks on a letter, the 
page should scroll somewhere in the vicinity of an item which starts with 
that letter.  To that end, what I would like to do is have some code inside 
of my dtml-in loop which gets the first letter from the current entry, 
checks to see if an anchor for that letter has been written, if not, a new 
anchor tag is inserted into the stream.  My problem is I don't really know 
how to code this up.  It seems like maybe that at least some of this should 
be done at the Python level but I'm not quite sure how to split up the 
functionality.

Has anybody done anything similar who would be willing to give me some 
advice as to the best way to go about solving this problem?

Thanks.

Quick, possibly misleading idea:  if you can give your Catalog entries a
brain class with a function "anchorGroup" which returns the first letter of
the entry, then you can use <dtml-if sequence-first-anchorGroup><a
name="&dtml-anchorGroup;"></a></dtml-if>

That should have worked.  You should be able to manipulate your dictionary
just as you would expect.  What happened when you tried it? What do you get
from <dtml-var expr="_['dictionaryVariableName']">?

"Brain Class?"  Could you explain that a bit?  It so happens that the 
objects I'm getting out of my catalog are instances of a ZClass that I 
created.  That ZClass inherits from a basically empty Python base 
class.  Is this what you mean by a "brain class"?  If so, are you saying 
that I should just define a method in my Python code which does the 
"anchorGroup" thing?

Even if this isn't what you meant, I think I like the idea that you are 
proposing.  I just need to make sure that I actually understand what you 
are suggesting.

Thanks.

Thanks for the info on your PDF implementation.

Here's my situation:
I currently have a Java applet that collects data from my users.  The applet
runs some calculations and sends the results to me via email.  I copy &
paste the data into a Win32 VC++ app I wrote that converts the data into
"Forms Data Format" (FDF) using Adobe's SDK for generating FDF files.  I am
using Adobe's fdf DLL right now, but I'm excited about the idea of moving
this to Zope - No more Applet for my clients to download!!!

I have ZERO Python experience.

I use PDF / FDF because I am filling PDF files that are created by a
governmental agency; these are 'State Standard' forms, so I want to stick
with them instead of generating dynamic forms using Zope.

Question:  Are you using a Python code supplied by adobe for generating your
FDF file?  If so, I would be VERY interested in any Python code you'd be
willing to share that ties Zope to the Adobe code.

Thanks for your response.

PS, I'm replying to you and CC'ing zope@zope.org.  Is this an acceptable way
to keep the mailing list folks in the loop?
PSS, what's your name?

Eric.

No problem. 

BTW: I just discovered this neat function called string.replace(). =)

This is almost certainly faster:

    string.replace(data, '\r\n', '\n') 

I swear, not a day goes by that I don't learn something new about Python.

Subject: [Zope] How to check memory usage in Python
Message-ID: <20000301225439.43329.qmail@hotmail.com>

Hi,

This is more a Python question. How can one
check the RAM memory usage of a Python program
from within itself? Is there such a function?
(Is it platform independent? I mean, does
such a function exist for most platforms?)

If such a function does not exist in Python,
how can one do it from Unix (or Windows) shell
calls?

thanks,

Hung Jung

Message-ID: <Pine.BSF.4.21.0003011851120.5888-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * XML.com has published another Zope article by Amos Latteier,
    titled "Advanced XML Applications in Zope"

    http://www.xml.com/pub/2000/02/23/zope/index.html


New Products

  * Software Product: PMPSurvey, by "sleeper"

    This is another survey product.  It supports single and multiple
    answer questions.  It may easily be embedded within other web
    pages, and reportedly sports a nice management interface.

    http://www.zope.org/Members/sleeper/PMPSurvey


Updates

  * Software Product: FSSession, by "gaaros"

    This product can be used to maintain arbitrary per-visitor data
    (session data) without burdening your ZODB with excessive
    transactions.  It does this by storing the sessions on your
    filesystem.

    This update, 0.2.3, uses cPickle, which makes it faster and more
    flexible.  There are additional new features.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: BannerFolder, by "lalo"

    This product randomly displays one of it's contained ads or DTML
    Methods.  There are provisions for tracking click-thrus and for
    limiting the number of times an ad will display.

    The current version is 0.4.

    http://www.zope.org/Members/lalo/BannerFolder

  * Software Product: ZRadius, by "Zen"

    This is a Radius authenticator.  It can be used on it's own, or in
    Zope as a GenericUserFolder plug-in.  This is a bug-fix release,
    bringing the version to 1.1.

    http://www.zope.org/Members/Zen/ZRadius


Zope.org items

  * Zope Documentation Plan, by Amos Latteier

    Amos Latteier is soliciting feedback on his Zope Documentation
    Plan.  It describes the initiatives to improve the documentation
    situation which are underway at DC, their goals, and the
    assumptions they are based on.  If you would like to offer
    feedback, Amos is available at <amos@digicool.com>.

    http://www.zope.org/Members/Amos/Documentation/Plan

  * Tip: Using PythonMethods on FreeBSD, by "als"

    This tip points out that a module required by PythonMethods (new)
    is not enabled by default by FreeBSD's python port.  It describes
    the solution.

    http://www.zope.org/Members/als/tips/PythonMethod_FBSD

  * All Product Releases, by Martijn Pieters

    This page is designed to be used with wget, Go!Zilla, or some
    other web-sucking tool.  It contains links to every Product
    Release on the Zope site.

    http://www.zope.org/Members/mj/AllProds

  * How-To: Wizards Made Easy, by "jspisak"

    This document explains a few techniques which make it easy to
    create simple multiple-page forms, like Windows' Wizards.

JC,

It was intended as a self registration sandbox environment for a Birds of a
feather group at a conference.

It basically allows users to self-register and then creates an area for them
to experiment with Zope.

Most people seem to be interested in the self-registration bit tho. (which
is quite strange as this is only a few lines of a python external method,
whereas most of the code is taken up with mundane stuff).

Is it at all possible to have this list set reply to?

since problems discussed and solved here are logged for others to search,
surely it would be best if, by default, replies to these messages came to the
list?  I know it's just a little thing, but it still bugs me.

I know that on other lists to which I subscribe this is done.

Anyone else have an opinion on this?

be great to have a seperate archive of ZWN as a more concise form of

    You've no doubt noticed that over the last couple of months, the
actual list content in the ZWN has dwindled to nil, excpet for
zope-announce.  :-/  I'll change that first paragraph of the ZWN next
week.

That depends on what you want the 'dynamic' content to be, and where you
want to get it from.

Perhaps the webmaster at zope.org could add a how-to search interface to
the how-to listing page? You know, one that searches only how-tos (or
how-tos and tips). Sometimes using the current search box yields lots of
not-so-useful links. :(

Don't forget that you can click on the cplum headers on the How-TO index
page to sort by that header, and a second click will reverse sort.

For example, to sort by date, click "Date".

can we really run apache without running zserver?  i've been running apache as

then maybe i'm doing something wrong.

My email window dies suddenly, before I could write what I intedned ...
looks like it sent itself waaay too early. Sorry.

Anyway, have you tried the batch processing instructions at
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.5.html
They should give you some insight as to how to get the first letter. You
may then be able to set a temp variable, called CurrentAnchor, for
example, that contains the last letter that was used to set an anchor.
Testing agaimst the CurrentAnchor, you should be able to set (if not the
same), or continue (if the same).

Unfortunately, ZCatalog apparently doesn't do reg-ex searches yet.
Otherwise, I'd say create your links a alink to a page that looked for
thins that started with that letter.

Alternatively, you could look at the howto, and give a range of letter,
say a-e, f-j, etc. and just use the batch processing capabilities in
DTML. :)


Just some ideas.

This may be well hashed for most here but I'm curious about this. I've
noticed that most true mailing lists operate like this zope list, whereas
the lists I subscribe to via services like eGroups perform more like Curtis
would like it. I'm with Curtis on this, it seems much simpler to just send
the reply to the list... if I hit "reply to all" the person I'm responding
to and the others that have particpated in the thread get at least two
copies... one direct and one via the list. I'd have thought that the
multi-copy thing would quite bothersome for most overloaded list-partakers.
Plus the fact that at least some of the time messages must unintentionally
never make it to the list. I can sure live with it the way it is... but can
you give me an idea why "the standard makers" thought the way they did/do?

Thanks

I think so.  A "brain" in obscure Zope parlance is a class used to enhance a
raw tabular record, such as a ZSQLMethod or ZCatalog returns.

Hmm.  Somehow you aren't getting a dictionary, then.  It's hard to tell from
just what you've posted where it's going astray.  Are you dtml-return-ing a
literal dict as in your initial posting?  How is dictionaryVariableName set?

You need to hack the z2.py file.  Go down near the bottom (look for the
string '# HTTP Server') and you will see that the HTTP server is fired
up on the IP_ADDRESS interface.  This variable is defined on line 252
and the default is an empty string '' which means, 'all interfaces'.

You can hack the code here to do anything you want, define a bunch of
interface variables, etc...

Yes, this needs to be done better, but short of comming up with a conf
file like apache and dealing with all that, it's probably no so
realistic.  z2.py is currently config'ed with command line options,
which gets out of control after a while.

Erm... since when is the reply to field of an e-mail header NOT standard?
Why is it a bad idea?  It means the default action of replying to a message on
this list is to contribute to the list.

I'm not saying you are wrong.  I just would prefer a clear explanation instead
of an outright "that is wrong."

Well, one aspect of it is summed up in two words:

	Mail Loops.

Mail loops involving mailing lists get real nastym real fast. While it
is true that most MTAs have capabilities to detect them, it is also true
few are very effective, and even fewer admins even try to enable them.

As far as the two copies aspect, I hit reply-to-all, and delete the
individual from the recipient list. Some mailers do it properly and have
group, and individual response options.
A third aspect is end-user filtering adn reporting. On lists where the
headers are munged, often the client reader doesn't display attributions
correct, or sort correctly.

I believe i mentioned that everything in my email was from my questionable
understanding of ZOPE.  However, since nobody else has said "erm.. no, that's
not correct" i'm led to believe my assumtptions were correct. (o8

Personally, I've only used ZOPE directly with ZServer, or via an Apache server
with proxying (i don't count my as yet abortive attemts with apache and fastCGI
:)

From a review of my original assumptions (and actually looking further) i may
have been totally incorrect, believing the Zope.cgi might be a program you
could simply drop into your CGI directory, and presto.

But from closer examination, and some testing, I don't belive this is true.

You still need ZServer, I think this person meant that ZServer wasn't
actually listening on any outside ports, just the local domain socket to
Apache.

FYI, Zope used to be able to run without ZServer, but it was single
threaded.  You can still do that now (I imagine) but if you want
concurency you need ZServer.

Subject: [Zope] how much resource?
Message-ID: <0003021244090L.00679@tokey.kedai.com.my>

hi all,
i'm happy to say that our site (www.emedia.com.my) has been running steadily
since feb.  and we got our first 1M hits per day yesterday, and zope didn't
screeched to a halt.

now i'm wondering how much resource <dtml-if> ..<dtml-call>, <dtml-in> affect
the sending out of data to users.  will a lot of if and ins bog down the
server?  i wanted to do two different page for the same contents i.e. pages
with tables, and without tables.  i intend to do as what zope.org does for
printable page where we set a variable in the url or maybe set a cookie.  to do
that, i need to have an if statement in all files looking for that particular
variable and render the apropriate header file.   will this affect response
time? i've looked at chameleon skin but could not grasp the way it works.

if anyone got better ideas, better solution, shoot it here.  thanks

Zopistas,

I notice that there are two "performance" options with Zope, proxying

The digest version is that adding a reply-to field clobbers legitimate 
reply-to headers, that many mail readers will have difficulty replying 
to the sender's address without resorting to cut and paste, and that
it renders the 'reply to all' function on most mailers useless. 

Further more, on 'reply-to' style lists it's quite common to see
replies to messages that were intended to be send to the sender end up 
on the list - to the annoyance of the list readers, and often the
embarrassment of the person replying.

This is the downside to CC style lists. One day it will piss me off
enough to write a patch for Mailman so that it won't send a message to 
a list member if they are already in the To: or CC: fields.

Better than the other way around. See above.

The Reply-To field is intended to be a way for you to indicate the
email address that you can be contacted with when the one your sending 
from doesn't necessarily receive email - ie, you're migrating between
accounts, or posting to a publicly accessible list from an account
that isn't receiving email from that list. Whatever. The point is that 
we want to keep people's reply-to fields where possible.

Yes.  Measureable in milliseconds.  It's really not that much to worry
about just doing one conditional evaluation.  What you really want to
avoid are long loops.

A reply-to field itself is not against standards, the requested _use_ 
of the reply-to field is. Slight difference ;)

[The applicable standard is RFC822.]
(of course, technically speaking, the modified subject line in this very
post is in violation of the standard, but since it doesn't tend to cause
nasty mail loops, it largely goes unnoticed :) )

Right. Now what happens when Joe User takes a trip, and sets his 'I am
on vacation.' autoresponder on? That response is sent to everyone. That
response generates another email to him ... continue ad nauseum. Or
consider the target email being no-longer-valid. You get a mailer-daemon
response telling everyone on the list about it; which includes the
target thus generating an error which....

Granted,  when all parts of the peices of the puzzle are coded properly,
that may be reduced in frequency and/or intensity, but unfortunately,
many, many manchines are not set up properly, and software isn't coded
correctly.

See my other response. On top of those, I would add the issues with mail
<-> news gateways and loops that can/do occur as a result of improper
header munging.

what Bill said about this issue having been turned over endlessly is true,

OK... here is something I was talking with my workmates about.  So, i send a
message to the list from somewhere other than my list registered account.  If i
was migrating accounts, or whatever, i would change my details with the list
server.  Mailing Lists should only be sending to registered addresses, surely?

so, the list server doesn't care where the message came from (or maybe it
does), and has a FIXED LIST (as far as it's concerned) of people to forward the
messages to.  Why does it care what is in the reply-to field?


on another point that is showing in this list... Reply-To-All buttons...

having reply-to set cirvumvents ALL the problems with duplicate messages, etc.
I have the option of a) Reply-To-All, and risk doubling to someone,
OR
hitting Reply, and getting the mailing list server to send it on to everyone
appropriate.

Be warned that this is a religious topic, and that the technical

the arguments from the other side.  The following URLs contains 
reasonable arguments on both sides:

Note that there are also some good pro-reply-to arguments under the

A small note: Given a message with a CC list list _and_ a Reply-To
set, a group reply on Many (even most?) MUAs will send the reply to
the Reply-To and ignore the CC list (IIRC the RFC is ambiguous in
this matter).  In this manner if an individual is using Reply-To
correctly (to hide the fact that they can't receive mail at their
From: address), they are also cutting the other recipients out of
the loop for replies.

Dangerous.

Conversely, if a list does do reply-to munging, this doesn't happen,
but the "proper" address for the original post is usually lost.

This is off-topic however.

Martijn, it is not problem of timezone setting. If yes I had to see the

29.2. date. I think that it is a bug in bobobase_modification_time. The
system time is OK, only problems with bobobase_modification_time.

A very meek greeting..


Ok... i have now seen the error of my ways.   I fully admit i was not aware
there were so many problems to what seemed like such a simple convenience.  I'm
sure i can live with trying to remember to set the To address.

Please,  _I_ require no further conviction in this matter.  The information has
been provided as i asked (thanks to all who did), and I have been made suitably
aware of why this (and many other) list avoids using the reply-to field, for
the simple matter of 'avoiding problems'.

Hey.. by the way... has anyone else noticed the prolific nature of vagueness in
RFCs?

Its the old game:

  Only what is stated is defined.  

  Some things are stated to be "implementation dependent".

  Everything else is undefined and might involve green hairy
  martians coming out of someone's nose.  Or not.  Or both.

RFCs are a little better (or worse, YMMV) than standards documents
(which aren't really written in english per se), as they often
concentrate more on "intent" than definition.

If you're running Debian/GNU Linux, you need the python-dev package,
but then why not install the zope packages?

Message-ID: <Pine.LNX.4.21.0003020306150.8576-100000@zaibach.twistedmatrix.com>

just to elaborate on a few common points that have been brought up on this
list, and covered here: 

> http://www.metasystema.org/reply-to-useful.mhtml

1) "It's against the standard":

Quoting directly from that article:

The first thing to consider is that RFC 822, the document which defines
the standards and usages for email, specifically mentions this usage in
section 4.4.3:

 A somewhat different use may be of some help to "text message
 teleconferencing" groups equipped with automatic distribution
 services:  include the address of that service in the "Reply-
 To" field of all messages submitted to the teleconference;
 then participants can "reply"  to conference submissions to
 guarantee the correct distribution of any submission of their
 own.

It's not "against" the standard.  It may be a quirk of the
standard.  Detractors, please familiarize yourselves before FUDding.

2) "It causes mail loops."

Can someone please direct me to a record of this actually happening?  
It's certainly not common, and I run all of my lists with munging on.  It
doesn't cause problems there.  Several other lists (yes, some of them are
even "real" lists) that I subscribe to use munging and have never seen a
mailloop.

3) "Autoresponders are upset by it."

If you're going to use an autoresponder, configure it responsably!  Better
yet, don't use one at all.  They are annoying.  Mail loops generated here
would happen anyway.

4) "It removes useful information."

If you're using the 'reply-to' header rather than your 'from' header to
encode the address you want responses sent to, I know this is within the
standard, but you're wasting my bandwidth and my time.  I don't need to
know both what machine you sent from and what machine you want me to reply
to.  Just put your own address in the 'from' header.  (This is what most
people do anyway.  I don't know anyone that works otherwise.)

5) "It removes freedom"

This is a crock.  Anyone with a reasonably written mailer can respond to
messages how they please: reply-to munging makes it easier to reply *only
to the list* which is almost always the required functionality.  If you
really can't live without the original reply-to header, maybe you should
consider posting a message to the list asking the person's private email
that you want to get in touch with: you should really be requesting to
take on-topic discussions off the list in the first place anyway.

Speaking of wasting my money / time, if you're going to be a detractor of
reply-to munging, PLEASE be thoughtful enough, at least, to remove the
inevitable list of 18 or 20 recipients that cruft up to threads over time.  
This 'conscientious' behavior, as described by Chip Rosenthal, has gotten
me CC:ed on some messages 2 or 3 times on unmunged mailinglists.  I find
this annoying, but less so than getting flamed for sending out 8 replies
to a single mailing-list message.  And I like to conserve bandwidth.

This is much-repeated stuff, but I hate to think that there's this image
that technically sophistocated people all hate munging and think it's
evil.  Chip's opinion is, as the author of the essay referenced above has
told me, treated as gospel, and there are definitely two views on this
topic.  I strongly adhere to one, obviously. :-)

(Please, no flames, no personal email about this.  I'm not going to be
convinced of anything, this is just a message to make sure that 'newbies'
to list administration don't think that there is one answer to this
question.  It's not really for those of you who seriously consider munging
bad, and I certainly don't hope to get the policy on this list changed by
it; that would only spark more discussion of this, and one extra email
once in a while isn't so bad compared to thousands upon thousands of
messages in this thread... ^_^)

Hi,

Can you please tell us what is the configuration of your machine.  I am
very interested.  We had our servers crawl to halt when we used Zope but
we had other things running at the same time.  So I will appretiate it if
you can give us the configuration.  Are you using a database? Is it on the
same machine or by itself, and if so what are the configuration of the
supporitng servers.

1M pages/day is a great number, I think that if a farm configuration is
used you can create an extremely dynamic and scalable site.

TIA
Adonis

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.


[RH] Um, without plugging my own document, you may want to check out my
'Changing Contexts in Zope'; reading your post it may be what you want. It
is not (meant as) a howto, but a bit more general. It should go into in the
ZBook of ZDP (watch this list for announcements about ZDP rsn). In the
meantime it is available from my member page:

In addition to the valid uses posted otherwise ...

Real life example:
 At work, I am within a corporate firewall. On my unixen, my email
address is local to the machine, ie. bill@somehostname.bigcorp.com. If
you reply to that, you will be wasting your time and badwidth, since you
_can't_ access it from outside the firewall. Thus, I (in this example)
add a reply-to that has a _useable_ email address, ie. one avaiable to
you, form outside the firewall. I personally know of several hundred
people who do this, and several thousand who _should_ be. And before you
say it, no, not every mailer lets you set the 'from' header.


The point? Now you know someone who uses it. ;^)

How can this be on topic, you ask? Read on. :)

I've notice a certain increase in the amount of 'sending mass email with
zope' messages lately, and not many solutions.

Since I don't zope on windows, one method I have used when wanting to
avoid the sendmail tag (I _was_ having problems with the friggin thing
not working), was to shell out and call mail (or mailx, depending on
your *nix) to send each message. Problem was, when doing that, the
'from' address was 'nobody@foo.bar.com'. Since I wanted replies, I had
to add the reply-to to get a response that was useful.

(Hey, I din't say it was a strong effort to bring it back on topic for
the list :)
Perhaps those wanting to send out mass emails *cough*spam*cough* with
zope, and not finding answers from within Zope and the sendlmail tag
(yeah, I still look at that puppy with suspicion and a sneer :) may see
this as an option

hi, we have a PIII 500 M, dual processor running rh6.1 with 712M RAM.  there's
only zope there, and mysql to cater for banner ads.  i'm using phpAds for now
until we got a commercial ad server or until there exist a mature banner ad
products for zope. (i'mm eyeing banner ad with interest tho..)  everything is
in one server, although we're looking at adding another server for redundency. 
don't know yet how to go about this.  anybody got any pointers?  maybe
failoverd? (http://ps-ax.com/failoverd/ ) or eddie?(www.eddieware.org)

the 1M number is hits, not pages.  we have max 600k pages/day last  feb.  this
is our second month so, hopefully zope lives up to its standard.. or i'll need
to find another job *grin*

I only noticed it today (2000/03/02): the undo logs show
2000/03/01, and so do ZWiki times. This appears to be a bug in
bobobase_modification_time.

<dtml-var "_.DateTime()"> does show the right time, and the 'Content
changed' notification Zope gives does too. The bug happens on both
Windows NT and Linux.

Thankyou.
However,to help my understanding how does this work?

Hope you don't mind - I've mailed my other, unanswered

Message-ID: <38BE5FB6.9EFCCE4C@open.ac.uk>

In the depths of a tree tag I want to pick up a
property of the "current" object without acquisition
if the property isn't present.

This code seems to work when used not in a tree tag
but when its in a tree tag it still finds the property
from higher up in the acquisition space.

What gives? How can I do this?

The version below doesn't fall over if the property
isn't present on that object, it just finds it by acq.

To fully round out this little performance study (small study of 
course) could you tell us what capacity the machine is at as far as 
you know, what Zope version you are running and with what 
configuration (Zserver alone, w/ Apache etc)?

These kinds of things are really helpful in determining Zope's 
ability to scale and in winning out the hearts of iCEO's.

Thanks,

Martijn, it is not problem of timezone setting. If yes I had to see the
difference in past also. And it was OK. The problem started with
29.2. date. I think that it is a bug in bobobase_modification_time. The
system time is OK, only problems with bobobase_modification_time.

The best test is creating a DTML _Document_ (not a Method!), with the
contents:

  Modified: <dtml-var bobobase_modification_time><BR>
  Current time: <dtml-var ZopeTime><BR>

Subject: [Zope] Problems installing Zope
Message-ID: <38BE54C2.B71E007E@rdel.co.uk>

Having just successfully installed and setup Zope and Squishdot
on an 486 Linux box (Debian packages made it dead easy), I
thought I'd move over to a SUN box as it is quicker and I want to
run a discussion group for the intranet here.

[SunOS 5.5.1 Generic sun4m sparc SUNW,SPARCstation-10]

After installing the latest python (and then re-compiling with
threads, doh) I unpacked Zope-2.1.4-src and ran wo_pcgi.py.
Everything seemed to go fine, so I simply fired it up using
./start. After a couple of seconds Zope (okay, Python) falls over
reporting that the ExtensionClass module couldn't be found at the
import in ZODB/__init__.py.

Actually, after investigation, none of the modules would load
from an import even though they all have .so files present in the
lib/python dir. Now, I don't know a thing about Python so I don't
know where to look to sort this out... Any ideas?

Is it something to do with shared libraries being handled wrongly
on SunOS 5?

Only other thing I can think of is search paths. I install
outside of /usr, but I can't imagine that would be a problem. Do
I need to set a PYTHONPATH or something?

Help...

I've put this into the collector, the bug is a bit weird for those, who
use bobobase_modification_time quite heavy, like me :)

aah .. the 'content changed' is a bit irritating, but it's only the
notice 'content changed' and a <dtml-var DateTime> in the next line.

Okay, my code was unclear in the example (though with a new created
method the modification time of the container should have changed too:),
but I'm quite sure, it's a bug.

Or, as someone else pointed out, you could use the -a parameter to z2.py.

Just run z2.py --usage for all command line options.

Uuuhhhmmm.. <g>

I just tested this myself. Here's my output:

   Modified: 2000/03/01 13:06:16.05 GMT+1
   Current time: 2000/03/02 13:06:17.86 GMT+1

Heh. One day off. And so is the Undo log.

My apologies for my unduly applied sceptisism. I'll go and hide now, and
investigate.

   I have Zope installed and running on Sun Sparc Solaris 2.5.1. Zope is in
/usr/local/Zope. There are 17 .so libraries in lib/python. Zope is running
fine: http://sun.med.ru/~zphd/
   The only thing - I am running under Apache with PCGI, no ZServer.
Nothing special for dynamic linking...

Or use CVS load_site which has a -I feature that for every index.html

Apologies for the late reply - flu :(

Yes. I create a DBH in an EM and fire away. All I get from the Zope 
system is a request of the form http://supercascade?root_id=240551 
and I start to do my queries. They are nested in the EM to 9 levels 
deep (but normally the first 4 levels are enough to get all the nodes 
of the tree with the relevant root_id). Getting the list of nodes is 
quite fast, about 0.8 seconds. Then I have to render them. I've got 
that down by a factor of ten (since this thread has started in actual 
fact!)

I've also found out just how fast a cached ZSQL method can be - one 
DMTL method that used query took 3.2 seconds on the first render, and 
0.06 seconds on subsequent renders. Obviously some more work needs to 
be done in this area and I'm looking into that.

I'm also told that our MySQL server itself does some caching ... 
looking into that.

Ah, I hadn't thought of that...my query isn't recursive however.

MySQL (MySQLmodule-1.4), DocumentTemplate and from 
Acquisition,Implicit in the main.

thanks for the thoughts Martijn,

Dunno if this is related or not, but I got some really weird errors yesterday
when trying to view some images I had created in Zope on the 29th.

All I was trying to do was view them using the image's view tab and I got a Zope
error. Something about an invalid datetime stamp I think but try simulating it
yourself if you want the exact answer...
They also appeared as broken images when I included them on pages using
<dtml-var image>

so, Zope doesn't like leap years? ;-)

A little while back I uploaded a patch to the ODBC Database Adaptor

Indeed it did, but unfortunately it broke a host of other things.

Anyone who downloaded the patch the first time around may be

I have a page that has the same SQL Method called a few times....

Do some more stuff

<dtml-in sqlMethod query=start_query>
Do some more stuff

Does anyone know the inner working well enough to tell me whether or 
not Zope actually makes two separate calls to the database or whether 
it makes one caches it and uses the results twice?

If you know and would like to expand on how Zope deals with caching 
SQL data that would be great I am trying to optimize my Zope 
installation and don't want to tax the database.

Hi,

Can anyone tell me what are the predefined error types
for the <dtml-raise type=...> tag, and how to use them?
The DTML manual talks about "Unauthorized", and
"Redirect", but doesn't give any details. I haven't found
how to use "Redirect" so far.

Thanks,

Stefan.

Dunno about raise, but if you want to do a redirect, try (untested,YMMV,etc)

<dtml-call "RESPONSE.redirect(url)">

Function TimeStamp_yad(int y) in
zope-2.1.4-src\lib\python\zodb\TimeStamp.c
expects a 1900 based year (i.e. 0 = 1900, 2000=100, etc.), 
for positive agruments, when computing (y+300)/400.

TimeStamp_abst(int y, int mo, int d, int m, int s)
seems to expect a 0 based year, on the other hand.

l = y%4==0 && (y%100 != 0 || y%400==0)

But it gets called with a 1900 based year in line 290 in 
function TimeStamp_timeTime(

Phil,
    nope.  Doesn't find the property called rubbish.

Baffled.
Perhaps its an architecure-related bug -

Here's what I've got.  First, I have a DTMLMethod named creditCardsAccepted 
which is defined as follows:

<dtml-return "
{
'Visa':'V',
'Mastercard':'MC',
'American Express':'AE',
'Diners Club':'DC',
'Discover':'DS',
'Carte Blanche:'CB',
'Japanese Credit Bureau':'JCB',
'Transmedia':'T'
}">

I then have a method called creditCardSelections which is defined as follows:

<dtml-return "creditCardsAccepted.keys()">

(I also tried <dtml-return "_['creditCardsAccepted'].keys()">)

When I try to "view" my creditCardSelections, I get the attribute error on 
'keys'.

Just tried that, same results (keys error).

(BTW, there was a typo in my message describing the dictionary I was 
returning.  The typo existed only in the e-mail, not in the actual code)

Subject: [Zope] Subclassing User
Message-ID: <200003021337.OAA05522@OSKAR.ingo.net>

Hi!

Can anybody tell me anything about subclassing a UserObject?
I have had some neat errors (including seg-faults and indefinite loops by just subclassing a ZClass from User Object)
When I tried to insantiate a Subclass of UserObject Zope quit.
(I did not change anything to the default constructors and expected something like "missing argument", but not an indefinite loop :)

I am using Zope 2.1.4 on Linux/x86 (2.2.13)

Thanks.

Regards, Ingo.

Followup,

I just realized that I had two definitions of "creditCardsAccepted".  One 
was defined inside my ZClass, and one was defined in the folder containing 
the ZClass.  The one in the container was just answering a list.  When I 
changed that one to answer a dictionary things worked.  I then simply 
deleted the DTMLMethod in the containing folder and now I get a name 
error.  Now I'm really confused.  After deleting the higher level method, I 
now have the creditCardsAccepted and the creditCardSelections both in the 
same folder.  It seems, however, that the creditCardSelections cannot see 
the sibling method.

I'm clearly overlooking something.

Andy,

Do all of the objects have a property 'rubbish'?

Try something like:

<dtml-with aq_explicit only>
  <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
</dtml-with>

This should check that the rubbish property exists and change what gets
rendered depending on that.

J,

In the advanced tab on the edit page of a SQL Method there is a entry box
for caching information.

You could start by looking there.

Phil,

> Do all of the objects have a property 'rubbish'?

No, only some of them.  The problem goes away if
I make sure that every object has some value for
this property but that's not a good solution.  The
code you suggest (the dtml-if ...) is exactly what I intended
but on my system (Linux slackware 7 + zope  2.1.4) it finds
higher level rubbish properties.  Actually its not really
called rubbish, that's just what I was using to check
it worked before using it.

It simply doesn't work - if it works for you lets find
out what's different.  Are you on a windows platform?
What Zope version?

Just to restate the problem for new readers:-

The problem is to use "dtml-with X only" inside a tree rendering
so as to be able to test whether the current object
has some specific property.  The code works outside trees but
used in a tree it still seems to find properties by
acquisition.

> 
> <dtml-with aq_explicit only>
>   <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
> </dtml-with>


This code finds "rubbish" at higher acquisition levels.  I know it
shouldn't but it does.  Anyone throw any light on it?

Andy,

Hmm, I'm confused.

I use this 'trick' all the time, here's a bit of code from a method of mine:

<dtml-with aq_explicit only>
    <dtml-if url>
      <a href="<dtml-var url>" title="<dtml-if status><dtml-var
status></dtml-if>" target=main><dtml-var ident></a>
    <dtml-else>
      <dtml-var ident>
    </dtml-if>
</dtml-with>

Which works beautifully.

Hmmm

confusion reigns!??!

Phil

Subject: [Zope] urgent! help! strange blockings
Message-ID: <38BE960E.32E0F12E@wildenhain.de>

Hello,

I cannot get ride of those strange blockings of zope.
This happens from time to time and leads some times to
minutes without action from Zope.
I increased threads pool and decreased it, I use a much
bigger object cache (memory is not an issue on the machine)
and I pured the database (with help of an extra machine)
Zope stucks with about 18% processor use and does almost
nothing at the moment.

Any posibility for an dead-lock?

Help is very appreciated!

Configuration: Zope 2.1.4, ZODBC, Database-Size: 66MB (after purify)
Some sessions with unsafed work, 50 threads for pool, NT 4.0 (ok, this
sux, 
but we have to use ODBC with strange Databases)

I posted a message about this this morning. In effect, yes you can 
use caching and it is veery fast (one second and subsequent renders). 
For your document, I think you'll find it will speed up by a factor 
of how many times the ZSQL method is called...

ps it's the 'Advanced' tag. Put something in the 'cache results for n 
seconds' box

I've tried to do something like you suggested, but it doesn't seem to 
work.  I'm probably not doing things quite correctly.  I've added a 
"getAnchorCharacter" method to my ZClass which correctly answers the 
character I want to use as an anchor.  I've tested this and know that it 
works.  I tried using "<dtml-if sequence-first-getAnchorCharacter> ...", 
but got no result.  Could you explain a bit more about how something like 
"sequence-first-xxx" works?  I haven't found any information on this form 
of a dtml-in variable.  Perhaps I'm just misunderstanding your solution.

In thinking about this solution, it seems that if I'm inside of a dtml-in 
iterating over entries in a Catalog, the objects known to the "dtml-in" 
aren't instances of my ZClass, but instances of some catalogging wrapper 
for my ZClass.  Therefore, it would seem that my getAnchorCharacter method 
wouldn't be accessible from within the dtml-in, but only from within a 
dtml-with which sets the object to be the object referenced by the catalog 
entry.

Can you clarify all this?

Thanks.

No light, no solution, only a bad workaround:

<dtml-let temp_rubbish=rubbish>
  <dtml-tree ...> # your tree code
  ...
    <dtml-if "rubbish <> temp_rubbish">
      <dtml-var rubbish>
    </dtml-if>
 ...
 </dtml-tree>
</dtml-let>

Check the Grouping Variables subsection of
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.html

I did give you the wrong syntax; it's <dtml-if first-getAnchorCharacter>,
with no "sequence-".

I misunderstood you.  The catalog wrapper is the "brain" which needs to have
the getAnchorCharacter method.  But... Suppose you add getAnchorCharacter as
a catalogued meta_type in your Catalog?  I think that would work.

Subject: [Zope] ZOPE!  I HATE YOU!
Message-ID: <20000302105256.A23108@devware.com>

It used to be that I was so open minded when it came to web
technologies.  I used to say "Oh yeah, pick whatever you want, we can
do it in that."  I used to say "No problem!  We can use your scripting
technology!  It's just as good as any other."  And I would, and they
would, and we did.  And we'd all stand around and say "Yeah
man... that's cool."

And then Zope entered my life.  And NOW I simply can't think of
virtually any project that Zope wouldn't do a better job of serving
than those *other* technologies.  It's very frustrating when every
time you see a project you think "Oh, Zope would make that SO much
easier!"  Especially any time someone mentions the word "Database" and
"Web" in close proximity.  The truly frustrating part is staying
focused on the problem-space when you have such a fun technology to
play with.

Now in some ways I'll admit, this is an exaggeration.  Obviously,
there ARE lots of cases when Zope isn't appropriate, but I just wanted
to shout out a big thanks for developing such an awesome system that
makes developing apps so easy to do.  Now if I could just get my mind
off of it's possibilities long enough to evaluate those OTHER
technologies objectively, then I'd be in good shape. ;D

Message-ID: <200003021716.MAA27689@amarok.cnri.reston.va.us>

I've made a new release of Oedipus, a Python package for presenting
data from the Open Directory Project.  
 
http://www.mems-exchange.org/software/python/oedipus/   

In v0.06, The improvements to the ODP code itself are pretty minor.
The major milestone is that, after some diligent sleuthing,
Jean-Claude Wippler tracked down an obscure bug in MetaKit that I was
tripping over.  A patch for MetaKit 2.0 is included in Oedipus 0.06,
so for the first time you can actually handle a complete ODP dump.
You'd better have 400Mb of disk space for the resulting data file,
though, plus 500Mb for the source XML files, plus 4-5 hours of
processing time (at least on a 550MHz Linux box).

The exported ZClass product still doesn't seem to work, though; if you
untar it in a new Zope installation, no Product is added when you
start up Zope.  Anyone else notice this problem?

Me too, I think. I haven't investigated this more deeply yet
but I noticed that all new News items created since March 1 in
the PTK portal I've been playing with get their
dates set back to 29 Feb the moment they are modified
(by being approved, for example).

and tried ./start again but the script seems to lock up after displaying the

apologies, ignore my pervious posting, try instead:

Subject: [Zope] [Newbie]  SQL database support on NT
Message-ID: <NDBBLMHEELDKLGHEEMJPIEMMCBAA.bac@ivc.com>

Hello All:

I'm just beginning to play with zope and really like what I see.  No Zen yet
but it's coming.

The project I'm working on must use NT as the server, much to my
displeasure.  I need to select a SQL database for the project and need to
find one that will work and play well with zope.  Searching through the
Guides and How-to's has left me a big puzzled.

Looking at the "Database Adapter Roadmap", it looks like there isn't a
direct adapter for SQLServer.  is this correct?  Will the Oracle adapter
work on NT?

If not, is my only choice to use the ODBC adapter?  Or the ZJetAdapter for
MS-Access (which I don't think would be sufficient for my needs)?

Any suggestions for database selection on NT will be appreciated.

Thanks,

Brad

It looks like you are indeed running the query multiple times. Unless you
are changing the data at some point internal to the process, which would
require your to "refresh" the results in order to have current data, you
could try:

<dtml-in sqlMethod query=start_query>
Do some stuff
Do some more stuff
Do even more stuff
</dtml-in>

Youd be "recycling" the result set, and sparing the DB backend.

I'll give that a try.  If I wanted to add a method to the catalog wrapper, 
is there a non-invasive way to do this or would I have to modify some 
standard Zope code to work differently?

We have been running an in house (approxiamately 100 users) contact management and order process site on NT 4.0 for several months
now using Visual FoxPro as the back end database (on a different NT machine) via ODBC and have had few problems. The zope machine is
a dell P3-400 w/256megs of ram. The db machine is a generic P2-200 with 512megs of ram. They are connected through a 100mbits
intelligent switch. However both machines now have dual port 100 mbits cards and we are in the processs of using the extra port on
each card to direct connect the 2 machine.

Our application is db intensive (every sql method involves at least 1 wrapper call to determine the AUTHENTICATED_USER's access
level) Unless there is network congestion and can display an order form (2 frames each the result of 5 to 10 sql methods) in about 2
to 3 seconds. (Response is 3 to 6 times faster via browser and ZOPE than throught the VFP apps that were originallly written to 2
this. )

VFP makes a very fast backend because if you are using only indexed columns and/or expressions the it can determine the record or
records entirely from the indexes meaning it never pulls data out of  the data file till it knows exactly which records to get.
Single record lookups - even with complex queries - are almost instantaneous.

LoginManager now has this capability. The loginForm is passed
"needroles", the list of roles one would have to have one of to perform
the action that prompted the login. Thus you could do:

 <dtml-if "'Member' in needroles">
  ... member login form ...
 <dtml-else>
  ... manager login form ...
 </dtml-if>

(note that 'Manager' is likely allowed to do both member and manager
things, and thus checking "'Manager' in needroles" would be true in
either case and not do what you want)

Hey guys. 

I'm currently in a minor bidding war with the Oracle group here over
whether we re-implement some intranet programs in Zope or in Oracle
WebDB. I've got them on just about everything, except calling stored
procedures. 
Now, I know that ZOracleDA supports Stored Procedures. So I'm guessing
that something like the following would work, but I'll be buggered if I
can figure out how. 

ZOracleDA Connection : oracle_da
External Method : find_target(search_string)
Oracle Package : Program1
Oracle Procedure : Proc1

def find_target(self, search_string):
  c=self.oracle_da.cursor()
  s=self.oracle_da.procedures.Program1.Proc1(search_string,c)
  return c.fetchall()

Am I missing something? I can't even get -- 
>>> import DCOracle
>>> dbh=DCOracle.Connect('user/pass@DB1')
>>> c=dbh.cursor()
>>> sth=dbh.procedures.pgm1_api.find_target('spam',c)

Subject: [Zope] SQLSession and Performance issues
Message-ID: <38BEDC9C.734F4754@exceptionalminds.com>

Hi all,

I have a form on which I am having some interesting performance issues,
I think, but am not sure that it is my extensive use of SQLSession
variables throughout the form.

I have a single page data entry form where almost every field  gets
stored in the SESSION. This form can take from 9 to 15 seconds to
display. When all my other forms take 1 to 3 seconds this is a
significant slowdown.

I am curious as to what methods may be used to reduce calls to
SESSION['varname'], or if I am even barking up the right tree.

Thanks.

In the 'utilities' directory of Zope there is a tool called

ok.  by "a ZODB" do you mean that the call in my external method
is trying to reopen the ZODB zope is using?  i'd assumed i was 
crating another one, with a separate FileStorage.

ok, then how does code in my external method get at that?
that is, how do i create an object and stuff it in the DB?
all the code examples i've seen follow the pattern in GetPeople().

> AFAIK, you simply need to create an instance of your object and set it as

how do i do this?

i get the feeling i'm just missing something, perhaps thinking like
a python programmer rather than a zope guru.  i feel like there's 
some big obvious point that has escaped me, and i'm waiting for the
big "AHA!".

so, one more try.  given the following external method:

import ZODB, ZODB.FileStorage


def GetPeople( self ):
	"Return list of people in DB"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( 'TestDB.fs' ) )
	connection = db.open()
	root = connection.root()
	people = []
	for key in root.keys():
		people.append( root[ key ] )
	return people

if __name__ == '__main__':
	for person in GetPeople( None ):
		print person.name, 'is', person.age, 'years old'


referenced from a DTML Method:

<dtml-in "GetPeople()">
	<dtml-var name> is <dtml-var age> years old.<br>
</dtml-in>

when i restart zope and view the method, it works once, but shows
no persons.  the second time, it fails with the traceback.

what do i change to make it work?

thank you for your patience.

I have not followed the thread but reading this particular posting, seems
to me that you cannot do what you want to do (at least in a
straightforward way). Importing ZODB declares all kind of global
variables/methods, an important one being get_transaction() which returns
the current transaction. So if you do a get-transaction() in your external
method which transaction should it return? And how would the two
transaction managers interact? Couldn't you just register your root object
with the current ZODB (the one Zope is running), by just setting it as an
attribute to the root object?

Again I have not followed the thread so I may be way off topic.

Thanks for investigating this - because TimeStamp objects are 
used in the object database, I don't want to make any changes 
to this yet until I can talk to Jim and verify that the fix 
won't have any impact on ZODB code (mon. morning probably).

Last I checked, setting an SESSIOn variable immediately did an update
on the RDBM which would explain the slowdown. I do not know what the
current situation is but I remember Anthony mentioning he was thinking of
changing it. You might trying playing with the source code and store all
changes to SESSION in a volatile attribute and call the SQL method at the
end of the transaction only (at least this is how I do it in FSSession).

Your only choice is the ODBC adapter if you want tyo use SQL-server.
We're running Zope on a NT server with SQL-server as database.
It works very well.

Thanks... but I think I really need to raise an error:
I want to invoke the redirect in the standard_html_header,
so if I use <dtml-call "RESPONSE.redirect(url)">, only
the header will be redirected (I think...).

Another, slightly related question: On my zope, whenever 
there is an error, the whole Traceback is printed on
the error page, and this doesn't seem to be part of the
standard_error_message. Does anyone know how to hide it,
or to put it in a html comment, like www.zope.org does?

Thanks,

Stefan.

If a FieldIndex is treated as atomic, it shouldn't go trough
the Splitter, right?

I found out that an hyphen in a field indexed as FieldIndex
breaks the index (this field is just not indexed, it seems). A
space works. Weird.

I was working with my ZClasses today and was confronted with something 
which seems strange.  I was editing a method defined in my ZClass when I 
tried to click on the "propertysheets" link displayed at the top of the 
edit screen:

DTMLMethod at  / ControlPanel / Products / <product> / <zclass> / 
propertysheets / methods / <method name>

When I clicked on the link, a basic authorization dialog was displayed.  I 
was already logged in as the superuser.  Why am I getting an authorization 
dialog?

Mostly just curious.

Thanks.

I guess it depends on what database you are using. If your
database is a remote server hooked up through TCP/IP port,
too many calls to SESSION could be bad. Also, if the session
data is large, during the transimission many packets have to
be send.

I don't have an answer... maybe you could describe first
what database you are using (Gadfly on the same machine?
remote database?), do you do many retrievals and updates?

------------------------

In the code SQLSession.py, there is a 'caching' variable.
SQLSession seems to cache variables that are already
retrieved or are recently updated. Try to set 'caching'
to 1 and see if that helps.

------------------------

As Pavlos Christoforou said, another strategy is to
have a single session data variable (a dictionary,
for instance), and then retrieve it, say, in your
standard_html_header and store it in your standard_html_footer
(or their equivalents.) This way you only need to access
the database twice per request.

------------------------

Please post back... I am also very interested. You
can also time performance by calling time.time()
in Python or <dtml-var ZopeTime> in DTML. I am
curious in the source of the problem... It would be
nice to find out whether the time is spent in each
database query or in TCP/IP packet splitting/joining/waiting.

regards,

Hung Jung

PostgreSQL running on the same box as ZServer.

Thanks for this input. I will go and take a look at it. I did not know
it was there.

Now this in an interesting idea, but all my attempts to computationally
build a dictionary within Zope have gone to naught. I would love any
advice on this as I believe it could very well be the key to this
problem.

This will redirect the whole page, as it gives a client-side redirect.

it only does this if you're logged in, otherwise it puts it in a comment
(or displays your standard_error_message)

This ist a typical Y2K bug, located in the module TimpeStamp.c, 
as I suspected earlier.
 
Since nobody followed my hint from earlier this day so far, I took 
the opportunity to dig a little deeper, learning how to build and

Given how little documentation there is, I don't claim having 
understood anything about, but noticing that the function

static double TimeStamp_abst(int y, int mo, int d, int m, int s)

gets called with y=100 (not 2000), 

changing the leap yar calculation

 l = y%4==0 && (y%100 != 0 || y%400==0);

to

 l = y%4==0 && (y%100 != 0 || (y+1900)%400==0);

in that function fixed the problem on my system.

erm.. one question... are you running Squid?  Or anything else on port 8080?

try "telnet 192.168.1.100 8080" and see what it says.


p.s.  if you want ZOPE to start on bootup, i put this in my /etc/rc.d/rc.local
file (I'm running RH6.2.. your rc.local may be elsewhere, or a different name):

/usr/local/Zope-2.1.3-src/start &

I actually run ZOPE as user 'zope', so i use:

su -l zope --command=/usr/local/Zope-2.1.3-src/start &

This is the detail I did not notice, previously. I thought you were trying
to store objects in your Zope ZODB; I didn't notice that the filename you
were passing to FileStorage was not Data.fs.

Sorry.

I don't understand why the problem is manifesting as it is, but I got your
code to work by modifying your code as follows:

- for key in root.keys():
-         people.append(root[key])
+ connection.close()
- return people

Opening a connection without closing it is a Bad Idea. I just can't figure
out what this has to do with the lock file on the database. I figured when
I closed the connection it was deleting the lock, but this is not so. So,
I remain confused. ;-)

Hope this helps!

That's why I didn't suggest a fix in my first analysis. I don't know 
anything about the internals of the Zope object data base (hey, I 
learned about Zope only about two months ago, so what do you 
expect?). So I don't even know whether it's just a problem of 
displaying the wrong date, or whether wrong time stamps are 
written to the data base. In the latter case, most people would 
prefer to have that bug fix yesterday. Inconsistent dates in a data 
base are a serious problem, and it's getting worse as longer it lasts.

okey dokey.  the setup is not that big.  we're just starting out and are just
feeling our way here.  what we have:

a PIII 500 M compaq 5500 ,smartscsi with RH 6.1, zope 2.1.3. i tried running
zserver with fast cgi but it choked with high load.  so, in the end, it's
apache with pcgi.  so far, it handles all the traffic beautifully.

what we want, however - reliability, availability of our site, so that's where
we need to look now.  caching is also another matter.  currently we enabled
apache expire module, but  not quite sure whether that would have any effect on
pages served by zope.

yes, and are you going to use sql in the future?  or just stay with zodb?  i
would think going with sql is better in the sense that most of us have that 2G
fs limit, and putting data in sql would help separate data from zodb.

Hmm. ZClass products aren't automagically imported; when exported, turn into
zexp files, either on the client machine somewhere or in the server's
$ZOPE_HOME/var directory.  To install them on another server, on must:

  * copy the *.zexp file into the new server's $ZOPE_HOME/import directory

  * import the *.zexp file into the "Control Panel | Products" folder.

You don't have to restart the new server, either, unlike "normal" Python
products.

Unless somebody borrowed Guido's time machine and retrofitted Butch Landigan's
ZPack proposal, that is?

Tres.

Greetings.

To start imapd should be set to run vie inetd. In the /usr/doc/packages/pop
directory look at the BUILD file. This has the information for setting up
inetd.conf to work with the imapd. In short you need to edit a few lines of the
inetd that comes with SuSE. Mostly you will need to uncomment the imap lines
they should look like this:

imap2   stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/imapd
pop3    stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/ipop3d

This will allow you to use the imap server or the pop server if you want to.

You may also want to check your configuration with a regular IMAP compatible
mail client like Netscape Messinger. FWIW I'm running WorldPilot on my test
server that is SuSE 6.2 (upgraded from 6.0) and works well.

Good Luck!
Jack

I checked my /etc/services file and it isn't showing anything connected to
port 8080.  Is there somewhere else I need to check?

//
// try "telnet 192.168.1.100 8080" and see what it says.
It says: "telnet: Unable to connect to remote host: Connection refused"

Then I added the "/usr/local/Zope-2.1.3-src/start &" line to my
/etc/rc.d/rc.local file, rebooted, did a "ps -ax" to see what processes were
running, saw that "z2.py -D" (in there 2 times).

So, I tried to telnet in agian and this time it said "Connected to
192.168.1.100"

Next I tried to connect to "http://192.168.1.100:8080/manage" with my
browser...

IT WORKED!!!!

Thanks a million Curtis!  I guess I just needed to add the line to my

Hi,

What is the difference between <dtml-call "...."> and <dtml-call ...>.  For
instance, if I have this directory structure:

|
+-base
    +-subfolder

from base,

<dtml-call subfolder.manage_addFolder(...)> doesn't add any folders, while
<dtml-call "subfolder.manage_addFolder(...)"> behaves as expected. It took
about an hour of experimenting before getting this right. Could someone
explain what is the difference here?

Thanks.

I would like to understand the source of your problem, too.

However, I think there is a misunderstanding here. In TM.py,
_registered is a class data attribute, which is typically
a trick for "initializing" Python instance data attribute.
That is, unless you explicitly do something like

  TM._register = 1

the class variable would never change. That is, TM._register
is always None. Always always. So there should not be any
problem in thread interference.

If x is an instance of TM (or an instance that has TM as
an interface, in the case of multiple inheritance), if you
look at the dictionary of x, i.e: x.__dict__ , you will see
that initially x does not have an attribute _register in
its own dictionary. However, x._register is a valid reference,
because it borrows from the class attribute. The statement:

  print x._register

would print out 'None'. As soon as you assign a value to

  x._register = 1

you create an attribute in the dictionary of x. That is, a
new item is added into x.__dict__ , which is totatally
independent of TM._register. So TM._register remains as None.

I'd like to take a look into it, too. But first I'll have
to learn what the flags _v_registered and _register mean. :(
I don't even understand what is a "transaction" in the sense
used by the transaction manager.

If I understand correctly, the definition of "transaction"
that you would like to use is one single HTTP transaction,
which lasts from the beginning of a foreign HTTP client
request till the end of Zope sending out the reply.

The question is: is this the same definition of "transaction"
as used by the transaction manager? Why would anything be
stored in ZODB?!? The HTTP "transaction" should not have
anything to do with ZODB database "transaction". The
"versions" that are stored in ZODB, are they FSSESSION
objects?

I'd like to look into all this. :)

regards,

Hung Jung

Calling tags with and without quotes follows mostly the same convention
throughout Zope. A tag without quotes, such as:

  <dtml-var myMethod>

is equivalent to:

  <dtml-var name=myMethod>

This says, "Include the variable with the name myMethod." The alternate
form is:

  <dtml-var "myMethod()">

which is equivalent to:

<dtml-var expr="myMethod()">

This says, "Include the result of the Python expression in quotes,
myMethod()."

In your specific case, dtml-call without quotes is equivalent to
using the name form, and thus does nothing. There is no attribute or
method called subfolder.manage_addFolder(...). Note that Zope would be
looking for this, literally, and would not interpret the period as an
application of a method to an instance.

Using the dtml-call tag with quotes is equivalent to the expr form, and
will thus interpret the period appropriately.

To convince yourself that this is the case, try including a DTML Method
using the expr form without parenthesis:

  <dtml-var expr="myMethod">

puts this in the response:

  <function myMethod at 8071cf8>

If you view this in a browser, you will not see it because your browser
will try and interpret it as a <function ...> tag, which, of course, does
not exist.

Hope this helps.

From my tests I am pretty sure the right dates are stored. It is just the
timeTime() representation of those dates that is wrong.

However, as you pointed out, the methods that provide the representation are
a bit confused over what format the year portion should be in when called.
This,and the fact its something so deeply part of the ZODB makes a fix
something that Jim can do.. =)

Again, greetings...

So I kept looking at what I had, and some things just did NOT look right.

So I fiddled.  I wrangled.  I bashed it with various bits of office equipment. 
And I got it to work!

here is a cutdown of what i used:

    <dtml-in "somQueryHere" size=5 start=qs>
      <dtml-if sequence-start>
        <dtml-if previous-sequence>
          <tr><td colspan="2"><a href="past_orders?qs=<dtml-var previous-sequence-start-index>">
              Previous <dtml-var previous-sequence-size> orders.</a></td>     
          </tr>
        </dtml-if>
       </dtml-if>
      <tr><td>STUFF</td>
          <td>FROM</td>
          <td>ITERATED</td>
          <td>QUERY</td>
          <td>HERE</td>
      </tr>
      <dtml-if sequence-end>
        <dtml-if next-sequence>
          <tr><td colspan="5"><a href="past_orders?qs=<dtml-var next-sequence-start-index>">
              Next <dtml-var next-sequence-size> orders.</a></td>
          </tr>
        </dtml-if>
      </dtml-if>
    </dtml-in>

it's much simpler than the example in the DTML book (IMHO), and it would be
faster in making only ONE call to whatever query it is you're using, not 3.

I'm not sure who is in charge of the DTML reference manual, but if i get a
moment i will be forwarding this code snippet on to them.

Message-ID: <007701bf84f3$98a60640$770da8c0@bbs>

I think it worth to encourage zopelist to move more things to the
client-side by modify a Zope fresh installation.

I found out there are many things hard-coded in
python or dtml in zope's source.

There are some things which can be do better in the client side. For
example, there were many dynamic folder tree writen in javascript which can
be more responsible than the zope tree tag (which the change of the tree
state require the help from server).

I would like to urge zopelists to explorer the client side authoring which
could actually give zope a dramatically change.

1. Remove those hard-coded parameters from the source and placed them in the
folder tree as attributes which can be modified or overwrited by manage
interface and acquisition.

2. Define the basic css (which zope.org have one) as default elements with
the fress zope install.

3. Make the current Zope tag comply with xml standards : they should end
with /> or accept an end tag.

4. Collect open-source javascript codes and convert them into zope products
(like tree).

To build a dict in DTML, try something like this:

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('mydict',{})">

<dtml-call "mydict.update({'e':7})">

<dtml-with mydict mapping>
[<dtml-var e>]
</dtml-with>

<dtml-var standard_html_footer>

Plain python assignment won't work, as a "=" in python is a statement, 
and statements are not supported, only function calls.

to remove a key, use <dtml-call "del(mydict['e'])">

That could be good idea.

What would it add ? But a CSS-method or similar would be a nice addition.

Or even a general TEXT-method, with Content-type: as an attribute, so I don't 
need to write <dtml-call "RESPONSE.setheader('Content-type'. .... for all 
non-html methods

Why ? As has been revealed in several discussions before, it would be very 
limiting for DTML to force compliance to XML (dtml tags inside html tags, etc)

Making it only superficially similar would just confuse people.

If you could integrate it nicely with other parts of zope it would be a
welcome 
addition. But I doubt it would be easy, but if you can come up with a nice 
implementation, I'm sure it would be accepted in contrib.

IMHO this would be a very bad idea, because not all browsers are able to
use javascript. 

for example the tree tag works perfectly with lynx. This is really very
nice, because often we can't do many things with text only browsers, but
the tree tag is very powerful and lynx can use it: it's cool.

IIRC the recommended way was to use

<dtml-var REQUEST>

or perhaps

<pre><dtml-var REQUEST></pre>


It was further recommended to make a method called DEBUG in your root 
folder containing the above and set permissions so that only managers 
could use it.

You may want to check out the Zope-Mozilla initiative (and the related
Model/View discussion), which does something like this. It's on
http://www.zope.org/Resources/Mozilla. As this is Open Source,
contributions are more than welcome.

Another tree difficulty:

I have a tree widget in a page.
When branches are expanded or collapsed the
view you get in the browser moves.

Now I know this is somewhat unavoidable but
can anyone think of a way to limit the effect
for example some way of making the text above
the newly-expanded bit stay still and just
re-rendering that below instead of shifting
everything around?

I am using Interbase 5.6 with ODBC.  It sucks. 2-3 x a week the ODBC
connection gets lost, and the Zope ODBC adapter refuses to reconnect.  

It usually happens after I enter the management screens as well.

I have to shut Zserver down, and restart it.   I think the problem must
be the ODBC driver supplied by Interbase Corp.

I'll probably shift it over to MS Sqlserver as people don't seem to
report problems there.

[ preventing acquisition within a tree-tag ]

After going through the archives my third (and hopefully better tested)
trial with this :-)

In your Extensions directory create an external python method with this
code:

def prev_acqu(self, prop):
    if self.__dict__.has_key(prop):
       return getattr(self,prop)
    else:
       return ''

add it with the id prev_acqu (or anything else you like better) to a
folder in the acquisition path.

In your tree code do:

   <dtml-var "prev_acqu('rubbish')">

If you choose a different id, of course you have to take it here, too. 

Apologies again for jumping into this thread without exactly verifying
my code examples yesterday,

Forget it, its a mad idea.  I was dreaming up some
mad-brained scheme using targets (so eg each
expansion could ensure that the very top of the
page was visible in the browser) but its crazy.
I need a weekend.

That is not "locked up" -- that is the normal "blocked waiting for requests"

Because the FTP server code is in Python, the chances of this 
being a real classic "buffer overflow" (of the sort that can 
start to overwrite unintended memory) is slim (I expect that 
the worst you could do is send something so long that it consumes
all available memory and causes Python to raise a MemoryError).

We should look into the handling of those commands though. I don't
manage the FTP code so I don't have enough deep Zen to know what 
the "correct" behavior is, but it seems that if it's giving a 
false positive then something is probably not being handled 
totally correctly. Can you make an post in the Collector about 
this so that it doesn't get lost in the flow of the list?

Thanks!

You might also look at TimeStamp_yad() (line 117 of the same file in 2.1.4)::

  static double
  TimeStamp_yad(int y)
  {
    double d, s;
  
    d=(y-1)*365;
    if (y > 0) 
      {
          s=1.0;
          y=y-1;
      }
    else
      {
        s=-1.0;
        y = -y;
      }
    return d+s*(y/4-y/100+(y+300)/400);
  }

I _think_ the last line should be::

    return d+s*((y/4)-(y/100)+(y/400));

"every fourth year, except century years, except every fourth century".  Perhaps
the original was "working" to compensate the base 1900 vs. base 0?

Weirdness...

I've almost got mod_pcgi2 setup to serve my entire site fronted by Apache
but I've run into one final snag.

When I access the home page of the site I notice that the BASE HREF
returned by Zope is saying its http://XXX/index.html/

Apparently Apache is appending the Index name for the folder?

I tried Options -Indexes but this didn't solve it.

Anyone have a valid configuration for this situation that I can take a
look at?

Thanks,

It's also worth mentioning that when you do this to call DTML Methods and
External Methods some things automatically get passed in. When you use the
expression form, these things are not passed in. The most important thing is
that the namespace is passed along to DTML Methods and this() and REQUEST
are passed along to external methods. I haven't looked at the python source
to know exactly what is passed in these cases, but you generally will get
what you want if you do this for DTML Methods:

<dtml-var "myMethod(_.None, _)">

and this for external/python methods:
<dtml-var "myMethod(this(), REQUEST)">

   This has nothing with mod_pcgi2 or Apache - it is Zope who adds BASE.
May be you can eliminate it with SiteAccess. It seems you are trying to do
virtual hosting with Apache, and Zope is not capable yet of virtual
hosting, but SiteAccess is one method to helps.

Subject: [Zope] Trouble with dtml-in
Message-ID: <38BFDB65.3AFA8796@lunateks.com>

I'm having trouble with using dtml-in in batch mode.

A syntax like this:

<dtml-in objectlist size=1 start=qs>
  <dtml-var sequence-item>
</dtml-in>

Works properly when qs=1 or qs=0 (treated as 1). Anything more than 1
causes it to ignore the "size=1" setting and loop through all the
elements in the list. The "next" and "previous" parameters exhibit this
problem too.

I can't understand what I'm doing wrong. I'm using the exact code as in
the DTML reference (except for the size of 1).

I upgraded from Zope-2.1.1 to 2.1.4 to see if this problem had been
fixed, but no luck yet.

The only way I can find to get around this is to remove the size=1
parameter and use a <dtml-if "_['sequence-index']-1==qs"> to make the
batch work.

A colleague insightfully commented that while Dynamo has a high bullshit
factor, this is the reason it sells.

Take a look at this screen shot:

http://www.atg.com/news/images/screen-shots/systemconsole.gif

Dynamo is an expensive, closed product with a promotional web site that
smells like a million-dollar penthouse office space, replete with glass
walls and postmodern sculptures. It smells a bit funky, and the people
are possibly evil, but the product is of high quality, and it sells. And
because it sells, many people use it, and because so many people use it,
skilled developers exist in large numbers. Unfortunately, I can't say
the same of Zope.

Speaking of which, SNMP support for Zope would have been nice. Then we
could import the numbers needed to build monitors like the one featured
in the screen shot.

Sorry; I wrote sloppily and shouldn't have said "exported".  This is
the .tgz file produced when you make a distribution of a ZClass-based
product.  For that, you do need to restart Zope -- but the new Product
never shows up.  I haven't yet dug into Zope to see if this feature is
broken, or if something else is going on.

Subject: [Zope] Finding matches between two lists
Message-ID: <3.0.6.32.20000303091400.009538f0@pop.dnvr.uswest.net>

Hey all!

	This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

	---------

	The layout:

	Most of my code is in a Python Product, but there is still a bunch of dtml
used.

	I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

	Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

	---------

	The DTML attempt:

	I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

	<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">
                   <A href="<dtml-var site_url>/<dtml-var id>"><dtml-var
sequence-item></a>, 
                 <dtml-else><dtml-var sequence-item>, 
                 </dtml-if>
              </dtml-in>
            </dtml-if>
          </dtml-in>
        </dtml-with>
    </dtml-if eventnames>


	---------

	The Python attempt:

	So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

    def list_dj_list(self, namelist):
        """ should return a list of names & IDs from a list of names
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rnames = []
        for i in range(len(namelist)):
            rnamelist = rlist
            rname = filter(lambda x,p=self,s=namelist[i] : p.data[x].name
== s, rnamelist)
            if len(rnames) == 0:
                rnames.append('None')
            elif len(rnames) == 1:
                rnames.append(rname)
            else:
                rnames.append('multiples')

        return rnames

	---------

	The question:

	How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

	Thanks for any help!

If I understand you properly, then I think you'll find the Squishdot product
perfect for experimenting with a "real" zope site. Squishdot is a product
that emulates the functionality of Slashdot. You can read about Squishdot
and download it at

http://www.zope.org/Members/butchland/Squishdot

Make sure you install the TinyTable product too for the full tour.

As a post-installation test tool, it would be great to have a sample DTML

Does anybody have such a small collection of DTML pages to donate to the

Funny, I had never heard of Dynamo before you mentioned it here. 
Fortunately, I can't say the same of Zope ;)   I think you underestimate
the actual numbers of people and sites that use Zope.  I also think that
you are creating FUD so that you can get a feature you want to see 
implemented by the folks at DC.  Truly bad taste.

Please no.  There is NO reason to pollute Zope with something as insecure
as SNMP.

Subject: [Zope] 'helper' classes in External Methods
Message-ID: <v04220803b4e59f28a438@[128.240.198.13]>

Can someone give me a pointer to what these helper classes actually 
do? Can I use them to setup lists and dictionaries that will be used 
over the lifetime of the Zope server?

This is an example from an external method that Pavlos posted a while back.

class MCQ:
         ''' helper class for MCQ system'''
         def __init__(self, score):
                 ''' constructor'''
                 self.score = 0
                 self.total_score = 0

What I would like to do is load up a template_lookups dictionary with 
quite a few entries;

for template_id in self.Actors.RENDER.objectIds():
         renderer = eval("self.Actors.RENDER.%s" % template_id)
         template_lookups[template_id] = renderer

Thing is, I need access to the ZODB in one of my methods later in the 
module and so the above code doesn't work (too many 'selfs'!).

Anyone got any ideas?

Well, I am doing Virtual Hosting via Apache, but I'm only running one site
per instance of Zope.

Isn't this possible with pure mod_pcgi2?

Note that the servers listed as runinng Zope on Netcraft, are those that run
straight ZServer. Those sites that run Zope behind Apache, IIS, Zeus, or any
other webserver, will be listed under those webservers. So, a small
percentage of the number of Apache sites on the web, runs Zope.

From my personal expirience, I find that a lot more people run Zope behind
Apache, instead of pure ZServer. So, the number of Zope sites is a
significant factor higher than the 300 listed by Netcraft.

For an example, go to:

  http://www.netcraft.com/whats/?host=www.zope.org

You'll see that it is listed as running Apache (which it is).

Message-ID: <38BFF7BB.8EA2DA2B@vt.edu>

Hi, ed.

I think I am a bit dense today, so could not quite understand completely
what you are doing, but

If you want to find matches between lists, there is a cool thing in
Python that can possibly help you.  

Let's say I have two lists, list1 and list2, and I want to know what in
list1 is in list2, which is I think what you are going for.

list1 = ['n', 'b', 'r']
list2 = ['f', 'd', 'b']

def intersect(lista, listb):

    tmp = []
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp.append(anitem) #if there, append to the temp list
    return tmp                 #return the temp list

print intersect(list1, list2)  #should be ['b']

If I want no dupes, (if 'b' is in list1 twice, it will be returned
twice) I probably would use a dictionary instead of a list and return
the keys, e.g, 

def intersectnodupes(lista, listb):
    tmp = {}
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp[anitem] = 1    #if there, throw it into the doct
    tmp1 = tmp.keys()          #get the keys (arbitrary order, alas!)
    tmp1.sort()                #the keys are in arbitrary order no
longer
    return tmp1                #return the unduplicated list

In DTML, you can use the 'if athing in alist' thing too:

<dtml-call "REQUEST.set('list1', ['n', 'b', 'r'])"> <!-- or use your own
lists -->
<dtml-call "REQUEST.set('list2', ['f', 'd', 'b'])">

<dtml-in list1>
<dtml-if "_['sequence-item'] in list2">
<dtml-var sequence-item> <!-- do something with the things in list1 that
are in list2 --> 
</dtml-if>
</dtml-in>

Message-ID: <3.0.6.32.20000303184315.0093e620@poirot>

Hi,

I'm once again trying to get further in my test products.

* I've created a catalogAware ZClass, called KBItem
* KBItem contains an external method with id manage_afterAdd

Now, I can add KBItem instances in Zope without problems, BUT!

when having a ZCatalog inside a folder with the id Catalog and then try to
create a KBItem instance, I get following error (where testje is the id of
the KBItem I try to create) :

Zope has encountered an error while publishing this resource. 

           Error Type: ValueError
           Error Value: Uncatalog of absent id 'TEST_Folder/testje'

Help! I don't know what I'm doing wrong or what is happening!
What does it mean and what can I do?

Thanks in advance,

Tom.

if you have 2 queries one of which returns tuples containing events and usernames,

Subject: [Zope] Finding matches between two lists


Hey all!

This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

---------

The layout:

Most of my code is in a Python Product, but there is still a bunch of dtml
used.

I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

---------

The DTML attempt:

I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">

The Python attempt:

So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

    def list_dj_list(self, namelist):
        """ should return a list of names & IDs from a list of names
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rnames = []
        for i in range(len(namelist)):
            rnamelist = rlist
            rname = filter(lambda x,p=self,s=namelist[i] : p.data[x].name
== s, rnamelist)
            if len(rnames) == 0:
                rnames.append('None')
            elif len(rnames) == 1:
                rnames.append(rname)
            else:
                rnames.append('multiples')

        return rnames

---------

The question:

How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

Thanks for any help!

Hi Tom,

This might be because the CatalogAware class uses the manage_afterAdd hook
itself (CatalogAwareness.py).

In _your_ manage_afterAdd(self, item, container), try this (untested):

def manage_afterAdd(self, item, container):
      # do whatever want to
      CatalogAware.manage_afterAdd(self, item, container)

Hope this works.

Great idea!

However, no I get this error :

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: CatalogAware

Do I've to place somewhere an import of the CatalogAwareness library?
I'm afraid my knowledge of Python is to low to solve this correctly. Any
ideas?

Tom.

Hi,

I installed Zope 2.1.4 on my RedHat 6.1. I wanted to change the password given
by the installer. I tried : 
python zpasswd.py -p=mynewpassword access

Everything seems ok. I have new file called access which looks like the older
one except for the 'password' part.

1 - Do I need to restart zope in order to have the new password be effective.

2 - Even if I restart zope, i cannot use my new password. However if i replace
the new file called access by the old one, i can acces to the zope management
screen.

What have I done wrong?

Message-ID: <3BA3A8B61E4ED211ABB900A0C9615FE639C822@sev-mail.gtri.gatech.edu>

Okay, I'm new to Zope (3 days), but I was having such success with some
simple things that I thought that I could handle something tricky - I've
been working at it for a day now.

What I would like to do is present two selections (Division and Team) that
are populated from an ODBC connection.  I can do the population fine,
normally; but the trick is that I'd like to have the Team selection
dependent upon the Division selection (on the same web page).  I realized
that I couldn't do this on a simge form (or can I?), so I've assigned the
two selections to two forms.  I'm putting the two forms on the same page for
aesthetic (stubborness?) reasons.  Here's the code for the first form:

<form action="index_html" method="get"> Division:
  <select name="division" width=30 value="">
    <dtml-in sqlShowDivisions size=50 start=query_start>
      <option> <dtml-var age_group>
    </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>


This part works fine.  When I submit the form, the same page is regenerated
(with the 'division' parameter passed in).
One of my many failed attempts with the second form (which is also in
'index_html') is as follows:

<form action="TeamSchedule" method="get">
  <dtml-var division missing="Undefined"> Team:
  <select name="team" width=30 value="">
     <dtml-in sqlTeamsInDivision size=50 start=query_start>
        <option><dtml-var name>
     </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>

my sqlTeamsInDivision has 'division' as its only parameter.

When the user first enters the document, he gets an KeyError on 'division'.
I understand why this is so (the division parameter doesn't exist yet), but
I can't seem to work around it .

I tried changing the sql parameter to divisionname and changing the
<dtml-in> tag to:

<dtml-in expr="sqlTeamsInDivision(divisionname='<dtml-var division
missing>')" size=50 start=query_start>

and the error goes away, but the returned list is just blanks.  How should I
be handling this?

Also, when this form is submitted, it calls TeamSchedule with the 'team'
parameter, but I need to also pass the 'division' parameter.  How do I do
this?

Thanks in advance.

Subject: [Zope] Installation trouble on Solaris 2.6
Message-ID: <NDBBLONFDKEIFDBOFGJMCENCCCAA.ztf@one.com>

Hi all,

I'm trying to install Zope from source on a Solaris 2.6 system,
and I'm running into problems.

When I try "./start", I get the following error:

$ ./start
$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

PyImport_ImportModule: referenced symbol not found

I am new to Python, so it's less than obvious to me what is going
on here.  It looks like the ExtensionClass module is failing to
import, but I have no idea how to go about fixing this.

[Yes, I know about the precompiled Solaris 2.6 binary.  However,
I eventually will need to get this running on a Solaris 2.5.1 system.
Also, as far as I can tell, the binary release is not set up for
Apache integration, which is something I also need to do.]


Thanks in advance,

I think it is not a good idea to define classes in external methods. It is
better to define them somewhere in Shared (see the directory DC under
lib/python/Shared for example) and import them in your external method. 

import Shared.Tony.helper

 They can be very handy especially since python is way more elegant and
easy for complex logic in relation to DTML.

Not sure. need some more info. Did you try to use getattr to get to
object?


tmp=self.Actors.RENDER
renderer=getattr(tmp,template_id)

What kind of object is template_id?

People did report this bug elsewhere on the list. Apparently we're waiting
until monday when Jim Fulton can take a look at this. They're pretty sure
it's just a display problem and not something wrong with the object database,
but they want to make sure and check with Jim.

If you are sure that you can get along without the BASE HREF in a virtually
hosted (or other) Zope page, there is a way to fool the ZPublisher so it
doesn't include the obnoxious tag.  Just put

	<base dummy=dummy>

near the top of your method.  This turns out to be enough to fool the fairly
droidal scanning code into thinking that no additional BASE tag is needed.
Since it's an unknown attribute it should be a total no-op in browsers.  Of
course they could write a smarter parser in a future release so caveat
Zopor, but it works for now.  I wish they hadn't relied on that tag to begin
with.

Okay, never mind.  I figured it out.  I needed to use:

 expr="REQUEST.has_key('division')

to determine if the 'division' has been defined.

Also, the passing of multiple variables was obvious - just define a hidden
input field.

Thanks, anyway.

Message-ID: <007c01bf8553$1d6fa8e0$7b5addc7@laptop>

KM|Net News is a Zope through-the-web Product that allows you to post
news-style articles on your site. 1.1 is easier to install (because it
creates its own Catalog and does not have any external methods) and now
incorporates linking to external sites for more weblog-style publishing.
(KMNN is still different from Squishdot in that there are no discussions
attached to the articles and has different features for placement of the
articles within the article listings). You can see KMNN 1.1 in action at
http://www.byproducts.com

KMNN 1.1 also includes a new "contrib" method for trusted people to
contribute articles without review.

*** KMNN 1.1 requires PythonMethods. ***

You can get KMNN here:
http://www.zope.org/Members/tazzzzz/kmnn

If you're upgrading from an earlier KMNN, you may want to use the "Restore
Defaults" tab to "Rebuild Catalog" and restore "incoming.html". The new
incoming.html adds the fields for external articles.

This will probably be the last major revision of KMNN before the PTK.

Subject: [Zope] Logging users in Zope 2.x (second try)
Message-ID: <38C036C6.2300C61C@tm.ee>

How should I configure logging to get usernames into Z2.log

I first hoped to get it from Apache's access_log, but it saves 
username only when doing user authentication itself.

Then I thought that Zope at least would log it and migrated the 
site to Zope 2.1.3 to get logging support. 

Unfortunately it does still not log usernames and I have not 
found the place where I could turn it on.

Also the format is buggy:

Apache access_log:

193.40.215.135 - - [11/Feb/2000:08:29:55 +0200] "GET / HTTP/1.1" 200 2673

Zope Z2.log

127.0.0.1- - [11/Feb/2000:19:04:46 +0300] "GET /misc_/OFSP/dtmlmethod.gif" 200
1000

the bug being the missing space after the IP address.

what I was hoping for would have looked like:

127.0.0.1 - superuser [11/Feb/2000:19:04:46 +0300] "GET /manage" 200 1000

It looks like your dynamic linker cannot find your python libraries. 
There is an environment variable that you must set so that the linker
can find any libraries needed by shared library modules like
ExtensionClass.so.  I believe the env variable beings with LD_.  Do an
'env' (in bash at least) and look for something like that.  I never
remeber it cuz in Linux you just edit a file.

The binary will work fine with PCGI (Apache integration).  Whether it
runs on 2.5.x I don't know.

Hi Tres, Hi Jack,

Thanks for the infos/repost.
Is there no way to control UW IMAP to look for a specific folder in each
user's home dir for the INBOX root? Something like the way
http://host/~username/ mapping works in apache?

If not, then I'll add this instruction to the upcoming FAQ for
worldpilot, since this is the no.1 question up to now. (Jeeze, looks
like I'll have to install UW IMAP myself afterall, too.)

Cheers,
Ryan

In Amos Latteier's "creating XML Applications With Zope" at
http://www.xml.com/pub/1999/12/zope/index.html


There is an example that uses a Zcatalog.

He says to enter this into the expr field of the "Find Items to Zcatalog":

getNodeName()=='entry'


and click find.

When I do this with my own version, or even his version 
Zope gets this error:

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: Eval


it has to do with that entry in expr.

Is that a typo?

Sorry, coming in late here. The Env variable you need is LD_LIBRARY_PATH. Mine
is set to
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib:/usr/local/lib/mys
ql

(I know this 'cos I did a new Zope install the other day on an account that
only had 
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib
I started the Zope server under that account and found a broken MySQL product,
with an error message saying it couldn't load libmysqlclient.so.6. I had cold
chills going down my back for a looong few minutes....shudder)

Subject: [Zope] Assorted Zope problems
Message-ID: <20000303164457.A1221@velocity>

Hello-

I've been trying to get our existing Zope server (previously with ZServer
handling http) under Apache.  Here are some problems I ran into:

1. My biggest problem was that Zope uses the SCRIPT_NAME environment
   variable to construct it's notion of the base URI.  Unfortunately,
   SCRIPT_NAME gives the actual script name, not the URI.  So if you
   do a ScriptAlias, or any rewriting inside Apache, this isn't necessarily
   valid.

   An adequate solution seems to be to change
   PYTHONHOME/lib/python/ZPublisher/HTTPRequest.py line 211, to use
   DOCUMENT_URI instead of SCRIPT_NAME.

2. I couldn't get Apache with FastCGI and Zope working reliably.  On about
   1% of requests, garbage would be returned, resulting in random broken
   images or pages full of gibberish.  This is with the Oct 06 snapshot of
   FastCGI, compiled into Apache-1.3.12.

Anyone else seen anything like this?

Ed

Just curious, what does the result of a LIST with "~/Mail" look like on
UW IMAP?
What is the top node labeled as? 
I guess I could add a parameter to control the behaviour of the LIST
call.

"1%?  You were _lucky_!" (in my best Yorkshire accent).  I was getting
a much higher rate of errors (admittedly, I was only using the management
screen at the time as I was just starting out with Zope), but I ended up
switching to mod_pcgi2 to cure these problems.  The problem has been
mentioned before on the mailing list, but I'm not sure if a solution has
been found.

Platform is (for data point purposes): RedHat 6.1, Apache 1.3.9, Zope
2.1.4 and fastcgi Oct06 snapshot.

I want to write an object that can be traversed by ZPublisher.  The
goal is so I can write URLs like thingyForwarder/45/display, to get an
object corresponding to thingy #45, and call its display() method.

What's the Zope Zen way of doing this?  Implement an __of__ method for
acquisition?  Implement a __bobo_traverse__ method?  Make
thingyForwarder a Folderish object and implement all the folder
methods?

Subject: [Zope] Client-side Zope
Message-ID: <002501bf856e$7aee5640$770da8c0@bbs>

Continue to moving more job to the client, There will be more for Zope to
perform:

1. There will be necessary to generate various section-specific temporary
objects for CSS, DTD and Scripting files, framed or embeded html.

2. There will be necessary to support java or javascript access of zope in
the client.

In the first requirement, I would like to suggest an machenism to create an
section specific temporary object (which zope create the unique name and
substitute it) which dtml is able to write to it. The new object can be just
a new dtml-document. As in the following

<dtml-object dtdobject>
<dtml-object scriptobject>
<dtml-object cssobject>
<script lang="javascript" src="<dtml-var scriptobject>">
....

<dtml-write target=scriptobject>
function <dtml-var uniquevalidfunctionname>(){
   ....
}
</dtml-write>

I don't known about the solution of the second request.

In the long run, zope might encourage separate of control and data. The
current opening all tags in one dtml-method and closing them in another is
very dangerous if the control get complicated. I would like to suggest DC
consider a xslt like syntax which can also be used in server side xml to
html conversion if the client do not support it.

If zope is going seriously to the international market and xml, then unicode
is important in the core level.

I think __bobo_traverse__ will do what you want. You can look at the local file
system code in LocalFS.py as an example.

Nope, a bug.  The fix is in CVS but failed to make it into the 2.1.4
branch.

Put this line just after the license in
lib/python/Products/ZCatalog/ZCatalog.py

from DocumentTemplate.DT_Util import Eval, expr_globals

and it will work.

Take yer pick.

ZPublisher will try the following methods to traverse an object, in this
order:

__bobo_traverse__(request, name)

  Request is, suprise, the REQUEST object, and 'name' is the path
element ZPublisher is trying to traverse to.

getattr

  ZPublisher will try and get the subobject by 'name' with getattr.  If
this fails with an Attribute error then...

getitem

  ZPublisher will try to get the subobject by 'name' with getitem.  If
this fails, you get a 404.

One subtlety to be aware of is that __getitem__ seems to be called *after*
acquisition is given a crack for reasons that elude me. Since I've never been
able to get an explanation of how to use __getattr__ without blowing up the
acquisition machinery, this makes __bobo_traverse__ the only foolproof way that
I know of for hooking traversal. Someone please correct me if I am wrong.

The reason you have not heard of Dynamo is that Dynamo isn't being
hyped; Zope is.

There are other, non-Zope solutions out there, some of them quite solid.
I like to keep an open mind, and so should you. There are, indeed, quite
a number of people who have heard of Dynamo but never heard of Zope.

While my statistical data is entirely non-existent, I'll wager that
Dynamo-awareness exceeds Zope-awareness by a factor of at least two. ;-)
This isn't necessarily something to get upset about, and anyway I
believe, and hope, that the difference is shrinking.

Just a bit of background since you're accusing me of FUD.

Dynamo drives many of the web's most popular sites, and is in direct
competition with Zope, sharing the application server space with
contenders such as SilverStream, Sybase, Vignette, Jade, and many
others. Along with Vignette, Dynamo is one of the most successfully and
widely employed app servers solutions in existence. Whether this is a
good or a bad thing I'll leave for you to decide; I don't like Dynamo,
but I acknowledge its technical edge on Zope (and other solutions) in
several areas, such as clustering, reporting, personalization services,
e-commerce services, stability, and raw speed.

As an artifact of Dynamo's platform of choice -- Java -- there is
indirectly a "virtually limitless" expertise on Dynamo. If you know your
Java and your Enterprise JavaBeans, you already know Dynamo, and
stepping into your Dynamo shoes will be easy. Compare that to stepping
into Zope's multiple zens: acquisition, DTML, objects, Python. Note that
I'm not arguing against Zope here, which has a self-inflicted and
justified learning curve. However, managers will not necessarily respect
this difference in philosophy: The cost of training a person in the arts
of Zope will be measured against the cost of hiring an already-trained
Java wizzkid, and -- at least right now, today -- Zope will lose.

This situation has nothing to do with open vs. closed, either. Just like
Zope we're talking about proprietary (as opposed to standarized -- DTML
may be open, but it's still proprietary) technology. The fact that Java
is more widely established, and evolving faster, than Python is
unfortunate and outright infuriating, but right now that's how the cards
are dealt.

Dynamo also costs a lot of money. For small businesses, it costs too
much. A heavy-duty support contract with Digital Creations also costs a
lot of money, but you have a choice. On top of that, Dynamo is
open-ended but not open -- there is no source distribution.

My point? Zope already has a foothold in the small-time web site segment
of the market. However, big people wield big swords, and Zope, despite
its many powerful features, is not big enough for truly big things.

This is a two-part problem. The first part is that Zope's bullshit
factor is too low; it's not flashy enough to convince a senior manager
that Zope has enough clout for their business. It's a purely aesthetical
apprecation of Zope's poor-man, open-source philosophy, and the fact
that Zope does not offer a comprehensive monitoring system with a ticker
bar providing useless but impressive information does not fare well with
those who like to be bullshitted. We tech people know better, we know a
shiny surface tells us nothing about the engine underneath, but we tech
people are not holding the crucial component -- those big brown bags of
money.

Now, the second part of the problem is that underneath Zope's lacklustre
but entirely deceptive surface lies a powerful engine with scalability
problems. So far the only way to scale properly with Zope is a
combination of a load-balancing clustering system (eg., TurboLinux'
TurboCluster Server, which I can personally vouch for -- brilliant stuff
-- or Linux Virtual Server) with Digital Creations' ZEO, of which I've
only read about. There are Zope sites out there that are suffering
scalability problems (I won't mention specifics, other than that the
project I'm involved in is one of them). The problem is real, and
intrinsically related to Python. I wish I fix Python rather than sit
still and bitch about it; I periodically express my dissatisfaction with
Python's lack of performance, and I have certain ideas as to how to
improve it, but a research project like this would take time, of which I
can currently allot none. So instead I just bitch. ;-)

Finally, as for DTML being proprietary, Zope desperately needs native
support for XSL/XSLT as an alternative transformation language. I think
it was Michel who spoke vaguely of this being considered incorporated
into a future version of Zope. (At one point I planned doing an XSL
product, but I have not yet had a project to fund it with. So I'm not
just bitching here.) We also need better in-line scripting capabilities
than currently offered with External Methods and PythonMethods. This to
fight the creeping and ever-expanding notion that Java (replacing
Smalltalk) is the chosen, possibly even pre-destined, language for app
servers and middleware. Try to find an OODBMS, RDBMS, or application
server nowadays that does not use, or plan to use, Java as its
fundamental extension mechanism. I can think of a few, but they're few.
If you want to talk about FUD, you've got it right there.

Anyway, just my two cents.

Then please offer us an alternative, open, standarized interface to
monitoring data. The fact that SNMP in itself is insecure has little, if
anything, to do with whether Zope should be "polluted" with such
support.

An alternate route might be to have Zope export necessary variables
through a well-defined XML DTD, and then provide the necessary tools to
convert this XML output to SNMP, although supporting SNMP traps this way
would be difficult.

Perhaps supporting Performance Co-Pilot
(http://oss.sgi.com/projects/pcp/) would suit you better. Unfortunately,
PCP is probably not -- at least not now -- portable to Windows NT. In
fact, I'm not sure whether PCP will exist outside IRIX and Linux for
some time yet.

As far as pollution goes, assuming Zope exports the appropriate data --
in whatever form -- then support for performance/monitoring/management
APIs such as SNMP, PCP, WBEM, and to a lesser extent PDH, aren't
difficult to isolate into add-on products.

Thanks, Tony and Michel.  Unfortunately, LD_LIBRARY_PATH doesn't
seem to solve it, which is really puzzling.

The gory details are:

My base Zope installation is /usr/local/zope/Zope-2.1.4-src.  So,
ExtensionClass.so is in /usr/local/zope/Zope-2.1.4-src/lib/python.
My LD_LIBRARY_PATH is
/usr/local/zope/Zope-2.1.4-src/lib/python:/usr/local/lib:/usr/openwin/lib,
which ought to pick up ExtensionClass.so.

Anything else which would cause the import to fail?  I tried setting
PYTHONPATH too, in desperation, but it doesn't seem to make any difference.


Thanks,

Zach Frey


P.S.: I did try the binary distribution on Solaris 2.5.1, and can
report that it doesn't work.  Zope fails to start up with an unresolved
symbol error, so it really does require 2.6+.

If you consider separate code and data. If you think about putting
XMLDocument in real use.  This is one of the possibility:

using an xmleditor, the user can save the xmldocument to zope server as zope
automatically make all parts of the document reusable as zope object (is it
all what zope about? making a document into many small parts as each of them
be re-usable object?) This is process by zope automatically, the author do
not required to do extra works. The author can edit the document or part of
it and view the final result if the xml-editor support this.

To make this better, the author can embed dtml code in the xml document,
which make the document be active and live. You may have a system
automatically updated. Isnt it what zope designed to be?

The document inside zope can have multiple view as we can have dtml-methods
to transfer them into different view: html, xml+xsl+css, pdf, doc, etc...

If dtml syntax is not xml-complience, all of these will not happen.

A deeper change is to make dtml syntax more xsl like. I.e., make it block
oriented. So, the author is forced to code in good manner, instead of the
opening and closing tags were spearated into many places which I think is
very bad for maintenance.

I believe the problem is with ZServer/FCGIServer.py.  If you pull the latest
version from CVS (1.7), the problem should go away.  I had this problem a
LOT when I first started using it, but after getting the latest
FCGIServer.py (1.5.4.1 at the time), the problem went away completely.

Actually, what I am working on is abstracting that out. :)

What I _want_ to do, is to allow you to customize how you store the
dynamic data (like hits, clicks, remaing hits/click, etc.); whether it
be in an RDMS, Zope, File, whatever. I think I've got a pretty good
handle on it ... on paper (yes, I still do much of my code-writing on

I was thinking of an XML-RPC cronscript, though that wouldn't work on
windows boxes(?). Perhaps the recent Scheduler product will mature
enough, soon enough.

Subject: [Zope] PostgreSQL money weird problem
Message-ID: <38C06A0A.1DD2F6BF@uol.com.br>

Hi,

I'm with a weird problem with a report from a SQL database. I have a
field of type 'money', and every time I use it in a SELECT query, it
returns 0.00, doesn't matter the actual value of the field (in the
example bellow - the 'test' of the query -, the field Valor is of type
'money'):

 Id | Idcliente | Data       | Valor
  1 | 11        | 03-03-2000 | 0.0
  2 | 11        | 03-03-2000 | 0.0
  3 | 11        | 03-03-2000 | 0.0

SQL used:

select *
from compras
where idcliente=11

Running the same query on the interactive client, gives the value of
money:

credito=> select * from compras where idcliente=11;
id|idcliente|      data|valor   
--+---------+----------+--------
 1|       11|03-03-2000|R$50,00

 3|       11|03-03-2000|R$15,00 
(3 rows)

I'm using Zope 2.1.2, ZPyGreSQLDA, and PostgreSQL 6.4.2, running in a
Conectiva Linux 4.0 (kernel version is 2.2.5).

The definition of the class compras is:

Hi Ryan,

I thought I'd jump in on this since it gives me a good reason to learn a little
more about how IMAP works. ;-)

I logged in via telnet to my test system and determined (with some help
from the IMAP4 RFC) that the command being executed is 

LIST "" *

Since the UW IMAP server logs the user into their system account I can only
assume that this drops them into their home directory. If I execute the
requested command it will return nothing unless a Mail directory exists in the
users subdirectory. (I have one user setup this way from earlier tests and one
without the directory.) 

Executing the command LIST Mail * returns the same as LIST ~/Mail * for the
user with a Mail directory. 

I will attempt to do some checking on the functionality of the .imaprc file that
is sort of documented and see if this can be used to work past the problem.

Subject: [Zope] FYI: large files & linux.
Message-ID: <38C0AF01.C9887838@imeme.net>

Zopistas,

I was trying to get large file support on linux.  I succeeded, but only
partially.  Steps:

1. Download and install a kernel greater than 2.3.27. 
   It has the large file patch built in.

2. Reformat ext2 partition with 4k blocks:  
   mke2fs /dev/hdaX --block-size 4096
   the maximum filesize for ext2 depends 
   on the blocksize: with 4k blocks, it's 1TB.

3. Use Glibc 2.1.13-5 from debian potato.  
   unknown whether 2.1.12 from the gnu site is sufficient.

4. compile python 1.5.2 like so:
   CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" OPT="-O2 $CFLAGS"
\
 ./configure --with-threads

5. Now you can make files up to 4096 MB in size.  Why no bigger?
   I have no idea.  For me, at least, it means 1/2 as many zopes.

Optional step:

Wait.  In a few short months Linux should handle large files natively.

Ok, so you can't use the Zope distn that has a precompiled Python bundled (it
seems).

Try setting LD_LIBRARY_PATH as above and recompiling your Python source
distribution.

I know I had a real pain getting Zope-src distns running under Solaris (and
then found that our big expensive Sun Iron was half the speed - in pystones -
of my iMac! ...grrr) - but it can be done. 

HTH?

I would prefer this scheme too. You are breaking up a document into constituent
'blocks' in a different way than it is done presently.
I suspect you may get not only this but more in the future. There have been
similar thoughts going on in people's minds:

You'll have to call your DTML Method in a special way. When caling a DTML
object with <dtml-var name=DTMLMethodOrObject> this is automatically taken
care of. but when using it in the above way, you have to do this by hand:

  <dtml-in "creditCardSelections(_, _.None, *other arguments*)">

You now pass in the namespace as well, so your DTML knows how to access
other Zope Objects. This _will_ change in the future, BTW, this will be
automated for various reasons. You then won't have to think about all this
anymore.

Have alook at the following How-To, and espcecially the list referrenced at
the bottom of it:

  http://www.zope.org/Members/Pam/DTMLScripting

They will introduce you to the more advanced ideas of DTML scripting.

I've just moved from qlcomm.com to the current location. Your DNS server
must still be using the cached entry. Should be fine in a little while.
You can mail me at jace@radiolink.net until then (the address I used to

Here is what I use:


<dtml-var standard_html_header>

<dtml-with aq_parent>

<dtml-in "objectItems(['DTML Method'])" previous size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var previous-sequence-start-number>">
(Previous <dtml-var previous-sequence-size> results)</a>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" size=1 start=page>
     Document id: <dtml-var id>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" next size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var next-sequence-start-number>">
(Next  results)
</a>
</dtml-in>

</dtml-with>

<dtml-var standard_html_footer>

-----------
This doesn't work. When page=1, it's fine. When page >=1, dtml-in loops
all the way from "page" to the end of the list. I don't know why it's
doing that. The "dtml-in next" loop also does the same thing.

To explain the setup: I have a ZClass called "Article" based on
ObjectManager and set to accept only DTML Methods and Images. The above
code is in a DTML Method called "index_html" placed in the ArticleClass
(not when being implemented). I had the same annoying problem when
working with the results from an SQL query instead of objectItems. My
workaround then was to leave out the "size" parameter and instead use
dtml-if to compare sequence-index with page. It's ugly but usable when
there are only 4 or 5 pages.

I filed this in as a bug about an hour ago. Hope it gets resolved
quickly.

I've never used the DC Shared folder before. I've had a look in there as you
suggest and found some interesting things there. Time to read the docs on this

Definitely. I'm now using the XXX PythonMethods that Evan Simpson contributed

Sorry, I should be more specific. The above code is in a method - def
supercascade(self, tag_id): which is called from Zope with a query_string,
tag_id=231441.

That code works, but I need to load up the renderers everytime supercascade is
called. I'm looking at the helper classes to see if I can't load up the
template_lookups array once. Having said that, supercascade isn't called
anywhere near the number of times that make_html (the method that generates
the HTML for display) is, so it's possible that I'm flogging a dead horse
here.

> tmp=self.Actors.RENDER
> renderer=getattr(tmp,template_id)
> 
> What kind of object is template_id?

It's a DTML document of the form (this example has id = lecture_info);
---
<hr>
<p class="<dtml-var class>"><dtml-var content null="&nbsp;"></p>
---

make_html then has a snippet in it so;
try:
    template_str = template_lookups[theclass]
    template = DocumentTemplate.HTML(template_str)
    theresult = template(self, content=content, src=src, thetag=thetag,
level=level, the
class=theclass, header=header)
    return "<!-- theclass [%s] thetag [%s]  -->" % (theclass, thetag)  +
theresult
except:
    pass

which will then render the HTML appropriately. The *really* neat thing is when
you have more complex DTML in the template that has ZSQL calls etc. 

It works well, but I want to speed it up a bit - it can take up to 6 seconds
to render a 100k document, and if I've understood my Zope architecture
correctly, thats one thread used up (and I'm only using the default thread
count - I think it's six) until the request has finished. I'm sure that
previous messages on the list have implied that it's not worth changing the
number of threads to something like 32-64, but I'm not sure.

That's my main problem, people are hitting the site and generating lots of
requests that are in the >1 second range. With our Apache servers, we just
spawn ludicrous numbers of httpd processes and don't worry about it. Zope is a
different kettle of fish and I need to think differently about it.

Many thanks for your help Pavlos, I feel things are a quite a bit clearer now.

Of course.  Some people suspected a "user error" at first, though. 
:-)

Anyway, I wasn't reporting a bug anymore,  I found the probable 
cause in the TimeStamp module, in the meantime, and reported 
that findings, and a way to fix it, here.

Lets hope for the best. :-)

PS: people have asked my for the modified TimeStamp module in 
(TimeStamp.pyd on my NT system) in private mail, but I'd prefer to 
have them wait for an "official" fix.  Poking around in the object data 
base source isn't something to take lightly.

   How many items are there in objectItems? May be you need orphan=0?

I was very comfortable in my cozy PHP/MySQL world, until I saw Worldpilot.
I HAD to finally break down and
install Zope so I could have this.  Needless to say, my python/Zope skills
are a little lacking at this point.  I could
use some help.

Everything is installed and working great, except for a couple small
problems with Worldpilot.  I'll detail the most
significant first, and see how we do.

When I try to send mail, I get a Zope error with the following traceback:

The problem is obviously (to me anyway) that the call to publish in the def

getting one

I'm not sure I understand why, as this is a bit beyond my current
comprehension of python at the moment.
A gentle push in the right direction would be appreciated.

I have a DTML Dccument, stx_about that looks something like:

I will have to concur that Philip's book is a very good read. In
addition to his book he has great suggestions for your library of other
books. There are many of his ideas I think are wonderful, however I do
have some philosophical disagreements on others.

Some of his views of computers and programming are somewhat cynical even
if based somewhat on fact.

His version of scalability of which he focuses on a lot is basically
throw lots of money at it.
Start off with a highly scalable, multi-threaded, high quality webserver
with an embedded scripting interpreter. In his case AOLserver with Tcl.
He openly hates Tcl, but doesn't work towards using the language he
likes where he works. Further more he thinks doing so is folly. (my
interpretation) He states relational dbms are the only way to store
data. Other technologies aren't as mature or capable. And on relational
dbs only Oracle is sufficient. With others you are taking unnecessary
risk.

So to scale with Philip you develop with AOLserver/Tcl/ACS, buy big,
expensive hardware, buy big expensive database. ie: throw lots of money.
Since he prefers everything to be in a single machine you can only scale
up processors so much before the $$$ start escalating. Price an 8
processor anything versus a Linux cluster of 8 machines.

This is not enabling for the little guy. Yes I know of the ACS port to
PostgreSQL. I think that's great. However it is going to be a step
behind ArsDigita/ACS because it does require porting to become
PostgreSQL able.

He has disparaging remarks about app servers, many of which are true.
However, I do not necessarily believe that learning Zope/webserver is
more difficult than learning AOLserver/ACS. And when you've got Zope
you've got Python instead of Tcl. For some of us, we like that. :)

As a prodigal son here, I embraced Bobo/Zope early, became concerned
about scalability, wandered the websphere, and have come back home. I
have looked at Java/Servlets/Enhydra, AOLserver/ACS, etc. I decided to
follow my heart. I like Python and Zope. I like the Python and Zope
communities. This is where I want to make a difference and contribute.

Zope can enable the idea person, the little guy with a twinkle in his
eye and a big dream to pursue.

Sure it may not "currently" scale as easily as AOLserver/ACS for big,
busy sites. However, I think it is being worked on. I think that there
are options within Zope, Digital Creations. To a very large extent
Philip solves scalability with $$$dollars.

With Zope you can still throw $$$dollars at Oracle. You can also throw
some at Sybase, or whateverBase you desire. If that gains you
scalability or the ability to sleep at night it's available. With
ArsDigita/ACS the only supported option is Oracle.

If I believed throwing $$$dollars to solve scalability was required. I
would much rather throw $$$dollars at Digital Creations. Instead of a
$20,000 to $500,000 on up license of Oracle which is per machine, per
website, and potentially expires. Instead of requiring buying big, big
hardware for $$$dollars. Throw the money towards Digital Creations or
other Zope or Python developers to solve the issues which hold
Zope/Python back. In the end you will have helped build a bigger, better
open source software solution.

As a little guy with ideas and dreams, this is my view. By the time a
website grows enough to run into scalability and performance problems
with Zope it could potentially be making enough $$$dollars to contribute
to solutions. Try that with AOLserver/ACS/Oracle, start with $$$dollars
and then hope for the best.

My other thoughts wandered into employment. When I master either Zope or
AOLserver/ACS, would I rather work for ArsDigita (yes, they pay well) or
Digital Creations, if an opportunity presented itself in the future. As
I know both are growing companies. I like Digital Creations. :) 

On a side note, on the AOLserver mail list there is effort to embed
Python and get Zope running on AOLserver. I think it would be great to
see Zope/Python being multi-thread, multi-processor able on a high
performance open source, multi-threaded webserver. It would be awesome
to have an embedded Python interpreter in AOLserver without a global
threadlock that worked with AOLserver's multi-threaded API running Zope.

On another side. A website I just learned about does a performance index
of many sites and gives a average amount of time to load pages. This
could put into perspective Zopes performance from the real world, from
your own website.

you need to put HTML comments at the beginning and end of your DTML
methods. These will be passed unchanged to the final page, and any
problems pointed out by your validator will be pinpointed.

The problem is a bit deeper than that. Even if a validator could be
convinced to ignore DTML, you would still have the problem of trying to
analyze an incomplete HTML document.

Message-ID: <000c01bf85fa$bfd07090$0201a8c0@iridium>

Hi,

This question may be very naive but is there any way to use Zope as a
mailing list manager?

The sort of thing I want to do is :

1. Check a mailbox for messages.
2. Grab any that are related to my Zope WebApplication
3. Process each message "request" depending on its content.
4. Send one or more email replies to one or more recipients (easy with what
is already in Zope).

This might allow me to create a simple list manager for instance or allow a
virtual mailbox for all my WebApp members.

I have not followed the discussions you're referring to, so this may be
old news to you, but one simple way to provide XML compliance without
screwing up the HTML is to require that the HTML -- or whatever you're
rendering -- must be properly UTF-8 encoded. This is probably the least
painful way of attaining XML compliance. 

Unfortunately, it *will* be painful unless you're also using an
XML-compliant editor. The low-level DTML source will end up looking a
bit like this:

  &lt;html&gt;
  &lt;head&gt;&lt;title&gt;<var name="title_or_id"/>&lt;/title&gt;
  &lt;/head&gt;
  [...]
  &lt;/html&gt;

The editor takes care of the en-/decoding of character entities.

An obvious alternative is to use XHTML and XML namespaces, which would
currently -- because clients aren't usually XHTML-aware -- incur
additional XHTML-to-HTML processing on the server side.

Just on a personal note: I _like_ the curtesy reply to my personal account.
I redirect mailinglists to their own folder. On a list like Zope, that is
very busy, I would very easily miss replies to my messages.

With a good filter (like I use), I get a personal reply into my In box, not

Subject: [Zope] setting a DTML method's namespace from a product method
Message-ID: <874sameir7.fsf@wiz.wiz>

I'm having some troubles with manipulating the namespace of DTML
methods that are called from methods of product instances.

Some questions:

- How do I provide a DTML method with a full acquisition namespace, as 
if it were called in DTML, when I call it from a product class method?

- Does a REQUEST.set(somevar, somevalue) operation add a variable to
the namespace, or does it re-initialize a new request? I can hardly
imagine the latter.

- Does the local scope of a class method in a product somehow
propagate itself to external DTML methods that are called from that
class method?

Context of my problem:

My product has the following class:

class NFGnav(
	OFS.SimpleItem.Item, 
	Persistent,
	Acquisition.Implicit,
	AccessControl.Role.RoleManager
	): 

which ultimately calls a DTML method:

	  return self.NFGnav_ActiveMapItem(REQUEST)

I can set arguments for the DTML method, no problem:
	  REQUEST.set('NFGnav_ItemTitle', object.title_or_id())
before calling the DTML method works just fine.

However, the DTML method seems to lose it's acquisition context in the 
process. That is, if I define an 'myimage' instance somewhere higher up in
the site hierarchy, I get KeyErrors if I try to call
	<dtml-var myimage>
from the DTML method.

Funny thing is, if I request the URL of the product instance with the
'myimage' appended, this seems to have no problem:
		  /mysite/somefolder/ProductInstance/myimage
returns the image, whereas
		/mysite/somefolder/ProductInstance/someMethod/myimage
gives a KeyError. So the aquisition context seems to be intact at the
product class level, but not at the product class method level. 

I took care to provide (PARENTS, REQUEST) parameters for every class
method invocation, by the way.

I'd appreciate any suggestions in tackling this problem. Is this
question more suited for the zope list or for the zope-dev list, by
the way?

Even simpler than buying new hardware, switch to a system like NetBSD or
FreeBSD that has supported large files for years and years :-)

I'm not sure if you considered this, but note that LD_LIBRARY_PATH needs
to point to *Python's* libraries, not Zopes.  It's not python that can't
find ExtensionClass.so, it's ExtensionClass.so that can't find the
standard Python library module.

Your message sort of implies that you were ensuring that
ExtensionClass.so was in the library path, but the problem (I think) is
that the Python libs are not in your path.

I could be wrong and this could be an entirely unrelated issue.  Can you
run python normally?  Import stuff like cPickle?

Welcome back, Jimmie. I enjoyed reading your analysis and agree with
the thrust of it.

One thing you express, and which seems to have ossified into the current
received wisdom, is that scalability will be improved  when some
mythical deep pockets consulting client pays to get it improved ; then
everyone else will benefit. The problem is with the leap of faith it
requires from the client.

I currently have several clients who are very interested in Zope.
Their web sites already receive megahits. They are willing to pay money
for consulting, but certainly won't bank their businesses on the chance
that a magic key to scalability is found. As a consequence, the
greatest commitment they will make is to install Zope on a Linux server
on a VPN and "see how it goes" in a toy setting.

Therefore, I can testify that right now, today, Zope is being hurt by
the lack of a story on scalability.

If economics or policy dictates that Zope requires an "Angel" to
bankroll scalability research, we all have to be prepared for a
scenario in which that Angel never appears. Personally, I don't like
taking such a passive approach.

Two clear impediments to Zope's wide acceptance have been frequently
discussed on this list -- documentation and performance.

The documentation "story" has travelled on an arc which might be
expressed like this:

* Zope is Open Source. The community should document.
* The community can't take on the deeper Zen issues
* Volunteers from the community are time constrained
* DC hires a technical writer
* The ZDP is formed
* ZDP suffers from the lack of time available to its volunteers
* DC commits Amos to attack the general documentation problem and to
evangelize documentation

Documentation currently seems headed on a good track. What have we
learned from this trajectory? We've all learned that the Zope experiment
is different from other Open Source projects. It *needs* the cooperation
of *both* the Zope community and Zope's authors "shooting at the same
basket" to solve this.

I believe scalability requires a similar coordinated attack and that it
can't wait to be bankrolled.

ZEO, although a bit of a black box to us at the moment, sounds, on
paper, like a logical and credible attack on one aspect of scalability
-- the "throw hardware at it" approach.

No doubt there are other hidden opportunities. What kinds of hidden
opportunities? Who knows; they're hidden. ;>) But can we bring them out
of hiding?

Some of them are simple applications of available compute science, yet
I don't see these codified or set down anywhere. Perhaps we should have
a single HOW-TO repository for techniques and metrics people have
discovered, or just happen to know, in the performance arena. This
would be a FAQ along the lines of "I want to build my Zope site for
best performance. What things should I do? What things should I avoid?"
God knows this question comes up often enough.

Then there's the design and makeup of the Zope software itself. Its
original design requirement probably didn't put scalability at the top
of the stack. Here, there are probably other areas where the user
community can't know enough about inner workings and overall design to
contribute effectively -- but which require attention and a commitment
from the folks at DC. I'll mention a couple of things that pop into my
head. These are simply conjectural -- dialog starters. I'll be happy to
be shown that I'm dead wrong about any of these conjectures.

Zope began as a brilliant notion, of Jim Fulton's devising. It began as
a fews lines of code and has evolved to include better than two
megabytes of code. DC has evolved from a company with one employee to a
company with maybe a dozen engineers contributing to the code
base and is looking to hire twenty more engineers.

Among this team of top notch talent, who takes ultimate responsibility
for evangelizing and improving performance? Who leads the effort at
code review, with an eye to marshalling refactoring efforts?

What would be an example? OK, Devil's Advocate: Here's one area of
concern I have, perhaps unfounded. Digital Creations utilizes Use Cases
as a tool for design, in the Ivor Jacobson tradition. Use Cases have
many proponents and some detractors. One detractor is Bertrand Meyer,
author of the classic _Object-Oriented Software Construction_. His beef
with the use of Use Cases is that it poses a fundamental risk: it
encourages a functional approach, based on processes (actions). He sees
this as the reverse of O-O decomposition, which focuses on data
abstraction. He believes it carries a risk of reverting, under the
heading of object-oriented development, to the traditional forms of
functional design, by considering what the system does, rather than
what it does it to. He believes that, due to this risk, Use Cases
should be confined to use as a validation tool, not a design tool, to
avoid closing interfaces prematurely.

So let's say that Use Cases is a useful tool, but one that has a subtle
built-in gotcha. What are the dangers? Naturally, one is negative
impact on code maintainability/reusability.

Another may arise due to the need to balance two competing technical
concerns: the desire to encapsulate abstractions, and the need to make
certain abstractions visible to other modules. With regard to the
dynamics of subprogram calls, the placement of declarations within
modules can greatly affect the locality of reference and thus the
paging behavior of a virtual memory system. Poor locality happens when
subprogram calls occur across segments and lead to cache misses and
page thrashing, which can ultimately slow down the whole system.

Is Zope prey to this? I don't have a clue. Does anyone? Like I say, I'd
be happy to be shown that this concern is unfounded. But this is the
sort of creeping problem which can enter into a growing code base like
Zope's, as it is worked on by numerous people, each devoted on one
module or interface. Combatting such problems probably requires having
someone (someone blessed with both Jim Fulton's dedication to O-O
principles and an unbending zealotry for absolute performance)
committed to periodically flying above the code at a sufficient
distance to see such patterns and making bombing runs against the
target problems. As busy as everyone at DC is, I'm not certain that
anyone is doing that at the moment.

Thanks for the replies!

I did get it to work.  Here is what i did:





I created a new python method inside my primary class:

    def is_local_name(self, name):
        """ returns true with ID if name is a local user
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rlist = filter(lambda x,p=self,s=thisdjname : p.data[x].name == s,
rlist)
        return rlist






then called it using this dtml:

<dtml-if namelist>
  <dtml-in namelist>
   <dtml-let thisname=sequence-item>
    <dtml-if "is_local_name(_['sequence-item'])">
     <dtml-in "is_local_name(_['sequence-item'])">

I checked the WU IMAP mailing list, and found the following:

  http://www.washington.edu/imap/listarch/msg06947.html

In short, Mark Crispin (the author of WU IMAP) strongly recommends avoiding the
"*" wildcard altogether, using rather "%".  In this case, the '\NoSelect' flag
indicates (I think) that the item is a directory, and could be drilled into; 
or  perhaps the '\NoInferiors' says "this is a leaf -- don't descend" (my
ignorance of the IMAP protocol is showing).

I guess the idea here is to avoid using LIST once, but to do it "on demand" as
the user drills down the tree.  Mark also recommends using "LSUB" to pick up
"subscribed" mail folders.

Hope this helps!

Tres.

StructuredText expects list elements to be separate "paragraphs", where the
paragraph separator is an empty line.  Also, the indentation determines whether
the line before the list elements is treated as a header or as a paragraph.
Try::

 This is my document.
 
 - bullet1

 - Bullet2

which makes the preceding line a paragraph, or::

 Header Goes Here!
 
   - bullet1

   - Bullet2

Message-ID: <38C22166.EFC36537@aHIT.de>

Many thanks to Michael the author of TTImage
for pubishing your Product at zope.org.
You did a great job !

In order to create TTImage instances within DTML-Documents I made
some changes on TTImageClass_add because I got errors due to
empty BasicProps and DestinationURL.
Would be nice if you could include it in your next release.

I´m new with Python and especially with PIL so at the moment it´s 
not so easy for me to fix some further problems with the background
color.
When I set the backgroung color to 0xffffff the background color of the 
result is 0xfcfcfc ... seems to be an color palette problem ...   

Also I was wondering if it is possible to set the background to
transparent ?

I look forward to hearing your thoughts on my changes :-)

Andreas Heckel

Hi Matt!

I ran into this same problem. I finally traced it to a problem in the IMAP and
SMTP server options set in the setup screen. It seems to work best when these
are explicitly set to localhost and localhost. I'm not sure why but that's how
I got it to stop giving me that particular error. Unfortunately it will require
removing the current WorldPilot object and replacing it with a new one since
those parameters are not visible on the parameter tab of the object.

Good Luck!

Thanks, however I think they only work on date objects.

There is a DateTime() function to create date objects mentioned in the
DTML guide, but it doesn't seem to be documented.

Nevertheless, I would be interested in why atoi does not work for me.

Okay, it's simple enough - 

<dtml-call "REQUEST.set('mydate',_.DateTime('2000/12/31'))">

creates the date object I need to then reformat it.

Thanks,

It was never my intention to imply that throwing $$$dollars at DC was
required to improve scalability. What I said was based on perception of
such requirement. I'll admit "currently" Zope does not scale as well or
as elegantly as I would like. A statement I was making was that "if" I
(or anyone) "believed" that scalability == $$$dollars, I would rather
give to DC than Oracle. I believe Larry is doing all right on his own.
:)

I find Oracle pricing obscene. For the kind of $dollars it would take to
license Oracle I would rather see what DC could do with the additional
employees on beefing up Zope/ZODBs concurrency/scalabilities. There is a
thread on the WebDB forum about a group of people talking about putting
together a co-op to buy an Oracle license based on Oracles "unit"
pricing scheme for a moderately powered single processor Intel machine
it was going to run about $20,000. You would have to renegotiate if your
site got busy and you added a processor. Yuck!

I believe Zope's scalability issues will be solved over time regardless
of external $dollars. I believe more $dollars could speed up the
process, however it will still take some time. Currently ZEO is an
option but I don't know how well understood it is by the community.

Scalability Now can still be a sticky wicket.

Future things on Zope's side:
1. Moore's law.
2. Advances in Python and it's performance.
   a. Python becomes fully multi-threaded, multi-processorable.
   b. Stackless Python gets adopted and performance improves.
   c. Viper 
3. Advances in Zope, it's architecture and performance.
   a. Sam Rushing works miracles on Medusa/Zserver using Stackless
Python and Continuations.
   b. Zope does process pooling with each process on a different
processor. ZEO?
   c. ZODB does multiple data.fs's based on user design based on url
path directories
        allowing different Zope processes on different processors to
handle their respective dir.

It would be nice if some C/Python programming guru/genius would solve
Python's global threadlock issues where Python would scale on
multiprocessor machines. This would potentially render scalability a
moot point. The geniuses at AOLserver rewrote the threading of the
built-in Tcl interpreter so that it would be multi-threaded and work
properly with their nice multi-threaded webserver. Tcl's standard
threading I don't think (I could be wrong) is as nice as Python's.

If I had Oracle kind of money to throw around I would like to see
Python's thread issue resolved where Python becomes fully
multi-processorable. That would transparently scale Zope and benefit
other Python user's as well. It would enable Python/Zope to embed well
and play nice in multi-threaded webservers like AOLserver and others.
IIRC Apache 2.0 will be multi-threaded. If Python scaled on
multi-processors even a little guy could put together a dual-celery
machine a serve a nice site.

I agree wholeheartedly with you that there should be a concerted
coordinated effort between DC and the community to improve scalability
by allowing people to throw hardware at it. That was the primary issue
causing me to wander the websphere looking at options. I've learned some
things in the search, but I always looked back at Zope, even tho' my
wife liked Enhydra's logo, she thinks the otter is cute. Zope's current
logo is much nicer than the Purple and Gold. :)

If ZEO currently scales well, then DC needs some testimonials on their
website.

There definitely needs to be some documentation best ways to...
As you said, there is a consistent recurring thread of is ZServer alone
or ZServer behind Apache better.
Should I use a RDBMS or ZODB.
...

Some of us have no legacy issues. From scratch what's the best way to
design...

I agree the solving of Performance/Scalability and Documentation issues
would definitely help convert lookers into believers.

I am currently working my way through the docs and plan on helping
there.

While I was wandering, in my heart Zope was the project I wanted to see
succeed. I decided to put my mind where my heart was.  Possibly someday
some of my money too. :)

Some of your other concerns I can't address. However, one of the nice
things about Zope is that it is written in Python. Python imminently
supports playing and algorithm improvement. :)

Oops, spoke too soon.  Spent the last few hours trying to suss this out
without any progress :-(

I have a variable called START returned by a sqlquery

<dtml-call "REQUEST.set('startdate',START)">
start is <dtml-var startdate>

and that's okay

<dtml-call "REQUEST.set('month',_.DateTime(startdate).aMonth">

That, and variations of the same, dies with

Error Type: TypeError
Error Value: __div__ nor __rdiv__ defined for these operands

Why is that these simple little things are so difficult in Zope?

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

FreeBSD on intel architecture doesn't have the large file limit of Linux.

Not exactly true.  The *BSD's, like most of the rest of the world,
implement the basic POSIX file APIs which use a signed 32bit long
for file offsets in the base ABIs.  Ergo. if you are using the
equivalent of C's fseek(...SEEK_SET) (from beginning of file), you
are explicitly limited in the maximum size files you can process.

There are multiple hacked ways to work around this, one of which is
to allow offsets from SEEK_CUR to page-flip out into longer files
(just never use a SEEK_SET), or to implement another, parallel ABI
which takes a 63/64bit offset value.  Neither of which however helps 
the poor application which merely expected standards compliant
behaviour from its host and therefore didn't play by the local
"special rules",

Not completely correct.

man lseek... it doesn't work on file streams (fopen ), it works on 
file descriptors like poll and select,  and, it works on very very large files.

lseek is a POSIX interface, and has been a part of linux since at least 1995.
Indeed the BSD and Linux manpages are basically identical including this as 
a bug:

No, a Redirect is a client side thing. The response will tell your browser

You have to start up your Zope install in non-debug mode. By default, it is
started with the -D flag (see you start script). Remove that flag, and all
your tracebacks will be demoted to HTML comments.

Yup. Take a look at REQUEST.environ['HTTP_USER_AGENT'], which is also
accessible as:

  REQUEST.HTTP_USER_AGENT
  REQUEST['HTTP_USER_AGENT']

and in DTML also as

  HTTP_USER_AGENT

On Zope 2.1.4 (Win 32):
- I get "1900/02/28" when entering "2/28/00".
- I get "2000/02/28" when entering  "2/28/2000".

No errors. (I tested this on the Properties tab of a DTML Document).

The issue you report seems to be corrected in the last Zope subversion.


Cheers.

- To get the modify time for a file, use this code in a DTML document or 
method:

<dtml-with yourFileName>
   <dtml-var bobobase_modification_time>

or
<dtml-var "yourFileName.bobobase_modification_time()">

   How do I use bobobase_modification_time on a file object ? 
                      
   To get the modify time for a file, use this code in a DTML
   document or method : 

   <dtml-with yourFileName>                                          
   <dtml-var bobobase_modification_time>

   or 

   <dtml-var "yourFileName.bobobase_modification_time()">

   If your filename includes a dot, use instead: 

   <dtml-with "_['yourFileName.gif']">
     <dtml-var bobobase_modification_time>
   </dtml-with>

   or

Message-ID: <14530.26613.662250.268116@loki.1012internet.at>

I want to do the following tasks

A user enters a list of products. Such a list is equivalent to
an order. Then i want the user to enter some things for each
product. I don't want to implement DTML pages for each
combination of products and i want to present one entry
screen for each order.

I tried the following approach:
I created a Folder named 'Products'. In this folder i
created subfolders named after the prducts code number,
e.g. `4007', `4008'., ....

In each of these folders i defined a DTML Method `New' which
hholds the DTML code to create an input form fr this product. My
plan is also to create methods named 'Display', 'Edit', .... so
i can render the objects in different ways.

In anotehr page i want to do something like:

<dtml-in products>
   <dtml-var "URL1 + '/Products/' + _['sequence-item'] + '/New'">
</dtml-in>


but this doesn't work. Nothing is displayed. I also tries
<dtml-var expr="...."> and <dtml-call "..."> (the last one
was pure desperation).


So what's the correct method for implementig such a system?

[many good points cut away]

| I don't like Dynamo, but I acknowledge its technical edge on Zope
| (and other solutions) in several areas, such as clustering,
| reporting, personalization services, e-commerce services, stability,
| and raw speed.

Not that I have very much to base a comparison on, but I regard Zope
as both stable and fairly speedy.  I think I can guess in what regards
an alternative could be faster, but I'd really appreciate to learn
where Zope lacks in stability.  Can you provide any references?

I don't quite grok what "the situation" is referring to, but I think
you're wrong here, or at least mistaken regarding the meaning of
"proprietary".  Proprietary, according to Merriam-Webster, means this:

[cut from Merriam-Webster]
Function: adjective
Etymology: Late Latin proprietarius, from Latin proprietas property --
           more at PROPERTY
Date: 1589

    <a proprietary process>
3 : privately owned and managed and run as a profit-making
    organization  <a proprietary clinic> 
[/]

| factor is too low; 
[...]
| We tech people know better, we know a shiny surface tells us nothing
| about the engine underneath, but we tech people are not holding the
| crucial component -- those big brown bags of money.

I'm not sure if I agree it's a problem, then, that Zope lacks in the
big-department. :-)

| [under Zope's surface] lies a powerful engine with scalability
| problems.

What part of Zope's engine are you referring to here?  Do you mean
Python in general, are some specific part?  Like ZODB?

| So far the only way to scale properly with Zope is a combination of
| a load-balancing clustering system (eg., TurboLinux' TurboCluster
| Server, which I can personally vouch for -- brilliant stuff -- or
| Linux Virtual Server) with Digital Creations' ZEO, of which I've
| only read about.

I actually thought of ZEO as a very nice way to scale Zope.

| There are Zope sites out there that are suffering scalability
| problems (I won't mention specifics, other than that the project I'm

It would be very much appreciated if you could share some specifics.

[...]

I second that.

[...]

| -- in whatever form -- then support for
| performance/monitoring/management APIs such as SNMP, PCP, WBEM, and
| to a lesser extent PDH, aren't difficult to isolate into add-on

You are right about that, and I think that's a better way to provide
such support, rather then building specific support for any of them
into Zope.

2. what's wrong if there is no table-update after

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

A more zopish would be: define your 'New', 'Display' and 'Edit' methods
in the Products folder and use properties in the subfolders for the
different rendering. For example:

give each subfolder a property 'Description', and a property 'Price', in
your Display method put something like:

Description: <dtml-var Description><br>
Costs: <dtml-var Price>

So, with an url http://yourhost/Products/4007/Display

Display is rendered in the context of the object '4007' and its
properties will be used.

This is a bit unclear. Where do you call it (note that Zope doesn't know
'pages', it only knows objects, which define what's going on) and where
does the 'products' come from? I assume you want something like this:

<dtml-in "objectValues(['Folder'])"> 
   <dtml-var absolute_url>/New <dtml-var title_or_id><br>
</dtml-in>

objectValues(['Folder']) gives a list of all (sub)folders of the current
object. Note, that if you put this into a DTML Document, the list will
be empty, because a DTML Document is an object by itself, which has no
folders associated with. You'll need in an DTML Document a <dtml-with
"PARENTS[0]">, this will include the namespace of the folder object,
where the DTML Document is called from.

For each found item <dtml-var absolute_url> displays the absolute url

Generally, this sounds like a typical ZClass task. Have a look into the
ZClass tutorial and into the example products (there is one called the
boring product on Zope.org) for more informations.

Is START being returned as a string, or as a DateTime from your query? If
it's being returned as a string, you need:

  <dtml-call "REQUEST.set('startdate', _.DateTime(START))">

aMonth() is a method, not an attribute. You need to _call_ it, i.e.:

  <dtml-call "REQUEST.set('month', _.DateTime(startdate).aMonth())">

or, if startdate is already a DateTime:

  <dtml-call "REQUEST.set('month', startdate.aMonth())">

Another way of doing this, however, is something like the following:

  <dtml-call "REQUEST.set('mydate', _.DateTime('2000/12/31'))">
  <dtml-var mydate fmt=dd>-<dtml-var mydate fmt=aMonth>-<dtml-var mydate
fmt=year>

Voila.

The above does not seem too difficult to me. You made a few simple
mistakes, that's all.

I forgot that you can also use C-style formatting, which reads much better
in this case:

  <dtml-var mydate fmt="%d-%b-%Y">

Try (untested):

  <dtml-in expr="Products.objectValues()">
    <dtml-var expr="_['sequence-item'].New(_.None, _)">
  </dtml-in>

I would investigate ZClasses. It seems to me like you could end up with a
"Product" ZClass (though I might call it something else to avoid confusion
with Zope Products), which contains your New, Edit, and Display methods.

Depending on how much each Product differs, you might have a
WidgetProduct, ThingamabobProduct, DoohickeyProduct, etc. Or, maybe you
can just get away with Product. I'd have to know more specifics to get
into detail.

I'm a relative beginner to Zope, so I'm not sure what I'm talking
about <grin>, but it seems to me from my limited experience that
you can't call out an object using a URL in a dtml-var.  Instead
you need an object reference.  So try something along these
lines (this is untested because I'm in the middle of my own
debugging mess):

<dtml-in products>
  <dtml-var "Products.get_item(_['sequence-item'],0).New"
</dtml-in>

I'm sure the above is not right from a Zope standpoint, and
the Python is probably wrong too, but maybe it will send you in
in the right direction.  What I'm aming for with that psuedo code
is to get the property of Products whose name is in sequence-item,
without rendering it (that's the ',0' bit), and to pick up
*its* 'New' property and render that.  Maybe a real Zope expert
can correct my code.

Or more likely, as others have suggested, using a ZClass is the
right direction anyway, which would avoid the whole syntax issue
<grin>.

It works as written

Subject: [Zope] More search engine woes
Message-ID: <E12RiXK-0007iL-00@ethereal>

I'm not sure if this is a PTK-specific issue, but I'm starting to
believe that it isn't. So I thought I'd post here with my problem and
see if someone could possibly point me in the right direction. I also
unsubscribed from the list recently, so please CC me with any replies.

I'm using Zope on a student organization website which I am
developing. Ideally I'd like for this to be an extremely popular
community-driven site, so a working search engine would be a
necessity. Additionally, I'd like to exclude unapproved items from
searches so that only moderated content is placed in the queue of news
items and ad banners which are being indexed. I'm also writing
site-specific documentation which is intended to guide members through
the process of creating news items, ad banners, etc., and I'd very
much like to have this content indexed as well.

Today I noticed that my search engine failed to produce any
results. Searching for the letter 'e' didn't even reveal anything,
which is unusual since E is the most common letter in the English
language AFAIK. So I tried digging into the ZCatalog documentation,
and poking around in the interface has confused me.

I created a help folder, and added an advertising document which
briefly explains how to create news items and such. Yet, I can't seem
to get this item to appear in the ZCatalog. In fact, the only item
which does appear is /Members/nolan, my PTK account page. Clicking on
the "find" tab and checking the "all items" checkbox seems to imply
that all items of every type on my site will be cataloged, but doing
this always results in only one page being listed in the catalog. Is
there some reason why the contents of help/ aren't being listed?

Thanks a bunch. If I can provide any additional information then I
will be glad to do so.

Ran into this one myself - the solution is to remove the DocumentRoot
directive, then just use the SetHandler and similar tags in the body
of the config file, though you can put them in a location container if 
you like.

Subject: [Zope] Setting attribute from DTML method in ZClass
Message-ID: <20000305223451.A15162@mimar.demon.nl>

Hi,

I've created a ZClass with a method 'force_update'. When a user is viewing
an object, there is a formbutton which they can press and force_update is
then called. So far it works. What I want my force_update to do, is that
it should set the needs_check (type boolean) in the object to true.
With <dtml-if needs_check> I print different things depending on whether
the object needs a check. From the Property sheet I can change the
settings. 

So, how do I put something like this().needs_check = 1 in a dtml-method?

Greetings,
    Chris Niekel

Message-ID: <010301bf86f3$d507db20$c3f28ec6@hikari.anu.edu.au>

I have a ZClass (Shot) which is nested beneath
a container ZClass (Storyboard).  I.e., an
instance of Storyboard might be:

Scene1 (Storyboard)
 - shot1 (Shot)
 - shot2 (Shot)
 - shot3 (Shot) ...

For reasons that I cannot discern, copying and pasting 
instances of Shot does not work.  I can copy them, but 
pasting creates a broken object:

  "This object is broken because the unknown product that 
   created it is no longer installed or is installed 
   incorrectly."

I suspect the copy has in fact worked because the title
in brackets is that of the source object.  This is an 
isolated problem on my site.  All other nested Zclasses 
work fine but I cannot pin down the difference.  This is 
Zope 2.1.4.

Has anyone else encountered this problem?

Darran.

Subject: [Zope] Simple Z Search Question - lost something while renaming
Message-ID: <000601bf86f4$06c5c5f0$0100a8c0@pinol1.sfba.home.com>

I'm trying to determine what might have failed in a Z Search generated set
of objects.

I used the Z Search wizard to create the search interface and tabular
report. They ran fine. I then renamed the data source (odbc) and both the Z
Search generated objects. I made sure that the input form reflected the new
report name. Now the input form will come up but when attempting to search I
get a "Object Doesn't Exist" type error.

I've also recreated the tabular report and it's input form with the Z Search
interface, and of course they work. I think the problem is with the report
as the original input form will sucessfully populate the recreated report.
What's interesting is that a compare of the text in the original vs the new
Z Search created report object show that they contain identical text.

I've also used Z Search to creat a similar "record" format pair of objects
that seem to endure any number of renamings, which is puzzling too.

I think that there are some variables hidden away, properties, whatever,
that I can't get to. This is probably pretty transparent to everyone, but
it's a bit of a stumper for me. In general this is a useful experiment as
it's obviously very important to know what effect name changes will have.
The docs state something to the effect that it's not too wise to change
names, but I've also seen that some name changes are propagated. So it would
be great to know what the pattern is. Maybe it's as simple as "rename at
your own risk".

hi all,

i installed fastcgi on my server and added -appconntimeout 0 (as suggested by
ppetru).  tried both unix and tcp socket.  however, i can't get 100%
availability.  there still exist connection failed (connection refused) errors
and incomplete headers 0 errors.

my config
rhl 6.1, pIII 500M, 776M RAM, oct6 fastcgi snapshot, FCGIServer.py from cvs ver
1.7, zope 2.1.3

i glanced at FCGIServer.py.  there were references of max connection (10) and
max request(50).  will this have any bearing on the connection refused error?

do i need to d/l other files instead of only FCGIServer.py?
i am also considering mod_pcgi2.  can anybody with fastcgi and mod_pcgi2
experience enlighten me?

This how-to will give you all the details:
http://www.zope.org/Members/lstaffor/zProperties

The short of it is that you need to call manage_changeProperties for the
propertysheet in question (which is actually what you need to do in Python
as well).

<dtml-call
"propertysheets.YourPropSheet.manage_changeProperties({'needs_check' : 1})">

It is very stable, indeed, so I take that back. ;-)

There are cases where I have been forced to kill Zope processes that
have falled into some sort of coma, but I've written these off as
growing pains in an evolving product. ;-) To date, Zope's stability
problems seem to have been mostly related to fragile database drivers.

I was really thinking of something else, and should have used another
phrase -- something like "high availability". Again, I have only read
the marketing material on ZEO, the product that supposedly provides such
features (load balancing, replication). Assuming ZEO works, strike that
from my list.

What I've observed is that I'm running Zope on Linux and accessing it from
a browser on a Windows box. I can create empty File objects and file
objects containing _text_ files without a problem, but as soon as I try and
include or upload an _.exe_ file it barfs with the commit_sub error.
I'm wondering whether there's something occuring inside the .exe file
that's playing up with the storage mechanism, maybe some kind of terminator
or something...

(I tried uploading files from Solaris and uploaded text files from there
fine, so I was thinking it was a windows problem, but upon trying them text
files worked under windows as well. It definitely seems to be an exe
problem instead.)

I mean proprietary as being controlled by a private party -- owned, in a
very liberal sense -- as opposed to being standarized. XML is not
proprietary. DTML and Java are.

I'm not as knowledge about IP laws as I would like to be, so I can't
really defend my use of this word or whether DTML is an intellectual
property of Digital Creations. Perhaps somebody else more suited to the
task could clarify.

If the suits in managements (assuming you work in such a place) tell you
to go learn Dynamo because that's what they want to use, wouldn't you
say it's a problem?

I definitely believe that Python is Zope's largest problem right now.
It's also, from a technical point of view, one of it's biggest assets --
Zope is becoming the killer application of Python, and might eventually
become the driving force to evolve Python, which is, I believe,
suffering from draught into the contributor department. Skilled
developers aren't flocking to Python to make it faster. Not right now,
anyway.

My hope is that Zope will change this, because Python has possibly one
of the slowest interpreters on earth. Python zealots -- and there is
such a beast -- will tell you that Python's performance is less of a
matter because what you sacrifice in speed you gain in power, ie.
computational expressiveness through a high-level, dynamic language.

For an example of a good, Python-like, dynamic language that is also
very fast, take a look at Dylan. In current implementations, Dylan is
not interpreted but rather compiled to native code, but in theory there
is nothing stopping anyone from writing a highly efficient Dylan
interpreter. Dylan's magic comes from its use of type hints, a system
which I had recognized as likely pivotal to improving Python's
interpreter long before I knew of Dylan. In Dylan, specifying a
variable's type is optional. When omitted, the Dylan compiler will
usually be able to infer the type from what you do with the variable
(ie., it sees you're assigning an integer to it; hence it can assume
that, for at least a stretch of execution, the variable remains an
integer). When you explicitly declare a variable's type, Dylan applies
the necessary code optimizations (such as using tight integer maths or
string copying) as well as static type checking. In Python, variables
can hold virtually anything, and this incurs a huge amount of checks.

Just imagine -- while Zope is running, thousands and thousands of the
same little checks are performed continuously, over and over again,
amounting to no uncertain overhead.

Python's biggest overhead comes from its dynamism -- the dynamic typing,
as explained, combined the object allocation system: most things is an
object, so a lot of objects are constantly spawned and torn down, often
in rapid succession because the compiler/interpreter can make few hard
analyses of when stuff is needed. Python also has a high function-call
overhead.

I agree.

No. Ask around, do some research. Ask Digital Creations -- they probably
know of a few, although I'm guessing that they might feel it would hurt
their reputation to tell. Many companies using Zope might not want to
tell you because it would hurt their position, especially if they're
public companies.

Here's one specific case that I'm personally struggling with. I have a
page that returns a large number of dynamic database results in a
relatively simple table. The results are first munged by a small Python
script. This stuff is slow. Internally, as far as I can determine
(through shallow study of the database code), Zope allocates a row
object for every row you access -- even if the row has been returned
earlier on. Zope has a 1-row cache for cases when you repeatedly ask for
the same row in succession. Zope also has a row cache that is useful for
static result sets. Yet, for dynamic result sets, the processing
overhead is huge. The overhead isn't so higher than any other overhead
in other areas in Zope, but it's especially painful here, because it
affects the generation time of a single page, whereas other kinds of
overhead are more evenly distributed across multiple pages and multiple
users.

Exactly. However, the necessary counters must be built into Zope at some
point, and exposed through a common (XML? Python/XML-RPC?) API. Then we
could attach publishers for SNMP, HTML, XML, whatever.

Which reminds me. Does Zope have a mechanism for extending the
Control_Panel namespace other than through the Product sub-folder? I'm
too lazy to check, and I don't remember if this was ever discussed.

I need record level locking in a database, and I need it quickly, without having

recommend.  Does Postgres allow record level locking?  I am on a linux platform,
and refuse to use any MS products, so don't go there.  Additionally, I need to
be able to easily export database content as both SQL statements and in some
sort of delimited text file format.  I can do the latter with Zope, of course,
but it is fairly slow and expensive.  MySQL does all of that nicely, but doesn't
have record level locking.  Please respond to me as well as the list.

Subject: [Zope] Zope Documentation Project (ZDP) Announcement
Message-ID: <38C31F68.123691B3@berg.net>

Dear Zopistas,


The Zope Documentation Project is pleased to announce the availability of
the new zdp.zope.org website, which aims to give the Zope community
an additional place for sharing knowledge, and for working together
on providing good Zope documentation. The new ZDP homepage already contains
many useful resources for the Zope community, which for the most part
complement the already existing types of documentation available on zope.org. 

We sincerely hope that Digital Creations will play an active role in
the Zope Documentation Project and help merging the existing Zope documentation
with the documentation provided via ZDP. To see what Digital Creation's Plans
for Zope Documentation are, have a look at:
http://www.zope.org/Members/Amos/Documentation/Plan

When we built the new ZDP site, great emphasis was placed on providing
ways to easily get aware of what is new on the site and to quickly get
an overview of what pieces of documentation need Maintainers, Writers,
Commenters and Reviewers. Thereby contributors are directed to the
documents and projects that need help. Everyone can contribute according
to their interest and level of experience.

We invite you to join the ZDP and to help building up a great
knowledge base on Zope. This also includes helping to customize and 
extend the ZDP-Tools, which is the software with which the ZDP site
was built and on which it runs. The ZDP-Tools are being developed 
on-site, and are completely written in DTML to allow for rapid 
through-the-web programming. Questions on the ZDP tools can either 
be directed to the ZDP mailing list or to me, as I am the ZDP-Tools
maintainer (Maik Röder, roeder@berg.net).

The most important sub-projects of the Zope Documentation Project are:

1. ZBook

   In this project, we are collaboratively writing a book about Zope.
   There are already many chapters, most of which are still drafts.
   We need feedback on these drafts, so maybe you can give some 
   comments directly on the drafts, or discuss them on the ZDP mailing
   list or directly with the author. The ZBook project is maintained 
   by Tom Deprez (tom.deprez@uz.kuleuven.ac.be). 

2. ZFAQ

   This project tries to answer the frequently asked questions on Zope.
   The project is in need of additional contributors, so if you
   have a  question on Zope, or an answer to share, then you are
   welcome to add it to the ZFAQ. If you want to help moving the old
   Zope FAQ  to the new one, then just contact Kamon Ayeva
   (kamon.ayeva@bureauveritas.com), the maintainer of the ZFAQ project.

3. ZSnippets

   Snippets are short pieces of DTML or Python code which come with a
   description of their purpose and how they work. This project is
   maintained by Rik Hoekstra (rik.hoekstra@inghist.nl), who will get
   an automatic email notification when you add a Snippet, so you are
   invited to help flooding his inbox ;-)

To become a ZDP member, write an email to the ZDP mailing list (zdp@zope.org),
and we will create an account for you. For the time being, this will give
you Manager rights on zdp.zope.org. Once we use a tool like the forthcoming
PTK Login Manager for automatically adding new members, we will have to
give more restricted access rights.

Thanks go out to Digital Creations for sponsoring the ZDP server at Codeit
Computing (http://www.codeit.com), a Zope Hosting Provider which is
kindly giving the ZDP project commercial support for an Advanced Zope
Hosting Server !

The ZDP site has not been tested under heavy load, so just in case 
you should experience down times, please report to the ZDP mailing list
at zdp@zope.org, and come back later. If you should not be able to 
reach this site under the name zdp.zope.org, try using the IP address
209.185.210.24 in the meantime.


So, you are invited to visit us at:

http://zdp.zope.org


Best Regards,

Maik Röder

Subject: [Zope] AS400, DB2 and Zope
Message-ID: <20000306032022.4041.qmail@www.eventera.com>

I am putting together a proposal for a steel, cooper and plastics
manufacturer based out of Germany, but with a large IT shop in 
Detroit. They are looking at Uniface Web Application Server, from 
Compuware, to do their web work. Although they approached me for 
my Uniface expertise, they seem open minded toward Zope. This is
their first experience building an application on the internet. 

Thier data is stored in a DB2 database on an AS400. While I have
used DB2, that has only been on MVS (don't the call it OS/390 now?,
am I dating myself?), and I was never the DBA. They seem to be
open minded about the operating system for deploying the web
application server, but I suspect that they will want to use
Solaris. I gues I am nervous because I don't know what I need
to know, and I don't have a AS400 laying around to play with.

Is ODBC an option for talking to DB2 on an AS400 from a Solaris 
box running Zope? How about from a linux box running Zope? Has
anyone heard the news on the OCI-based driver that DC promised
"real soon now" at the IPC8? Does anyone have that working?

I am going to pitch Zope and this project proposal on March 17.
There is a lot of money on the line, I appreciate any assitance and
my memory is long. If appropriate, please resond to me in private.

Greetings,


Look, I don't want to start any holy wars, just to get a head count, more or

Until now, I've been using Netscape, whilst desperately searching for some
replacement that didn't haemorhage memory.  I think I've even managed to narrow
down which part of NS is losing the memory (it's the edit box, which is why it
seems to happen quicker when working with ZOPE).

However, in my searches I've yet to find ANYTHING under Linux that comes close
to the functionality of NS.

As I said... I don't want advocacy here, simply name and version, and perhaps
a quick rundown of the reason(s) you chose it over others.

I am on windows and use IE 5.  However, when NS 6 (mozilla) comes out I am

Yep. In fact it goes quite a bit further:

It uses a BSD license so it's even more libre/lucre free than MySQL.

Er... do you mean ' I need to be able to easily export database

Or transactions, or constraits beyond NOT NULL and UNIQUE, or triggers 
or rules, or arrays or a dozen other things you'll wonder how you ever 
did without when you where using MySQL :-)

I'm running pretty much the same thing except for Zope 2.1.4.  I haven't had
any of the problems you describe.  I don't know if FastCGI changed from
2.1.3 or not, and I've only been using tcp socket.  I know this doesn't
really help solve your problem, but it does indicate that your setup
"should" work.

Subject: [Zope] beginner's question: references
Message-ID: <38C34B36.596AF966@primenet.com>

This is such a stupid question, but I can't seem to figure it out from
the docs.  How do I make an object in Zope reference another object?  I
don't mean containing like a folder, I mean one object referencing
another in a different part of the hierarchy.  For example, if I make a
class to represent movies, and another to represent theaters and I want
the movies to reference the theaters they're playing at and vice versa. 
How does Zope handle this?

Please try to frame an answer in the context of ZClasses, since that's
what I'm using.  (Or tell me if ZClasses can't do this yet.)

Thanks,
Perrin

Hi,

Problem:
    I have two web servers on one machine.  The first uses the standard
    port (80) the second (Zserver) uses port 8080.  How can I point
    to a page on the first server from the second?

Given:
    hostname:  monica.usc.edu

I've tried:  href="//monica.usc.edu:80/...

Results:
    * The page delivered to the browser has the site name including
      the ":80" stripped off.
    * Any foreign site name is NOT stripped off.

Well, you see... here's my problem.  I am using NS 4.7 on Linux.  And it chews
up memory like it's going out of style.  If I don't keep an eye on it, I wind
up in a swap-frenzy, and having to wait up to 5 minutes for response to any
keystroke (always the "KILL THE DAMN APP" keystroke :)

As for IE, i've had no 'back' problems with it when i do work from home (that

Help,

perhaps somebody from DC can help me swiftly?

Is it possible to use your own manage_afterAdd method in a ZClass which is
a descendant of CatalogAware Class? If so, how can you get this done?

Does there exist something like 'inherited manage_afterAdd', like in other
Object languages (eg Delphi?) : eg:

def manage_afterAdd ....
  <blablabla my stuff blabla>
  inherited (and does now performs the method from the parent class)


this doesn't seem to work :

def manage_afterAdd ...
  <my stuff>
  catalogAware.manage_afterAdd ... 

Help! Thanks in advance!

Tom.

Subject: [Zope] A zope fear...
Message-ID: <20000306033837.A12534@devware.com>

Several times I have heard folks mention a fear of "not being able to
get my files OUT of zope once they are in there." And usually the
answer is "Well just back up your Data.fs file and don't worry about
it."  I think perhaps this answer doesn't actually address the root
concern.  I think the root concern is one that I am actually coming up
against right now in debates about using Zope for a project.  That is,
if I stick with scripting languages or other traditional languages, if
I need to, I can always fall back on text processing tools to make
large global changes to my projects.  How can I do this with zope?
Many of us programmers are taught to learn to manipulate text like
magic.  Zope seems to take that power away from us.

So, the real heart of my question here is: I just spent 3 months
building a web site using Zope.  Suddenly, we decide to change our
database schema, and I now have to go through and change all 400 of my
SQL methods in zope.  How can I automate this process?  How can I do
this just like a good-ole multi file search and replace?

Answers that don't count are: Use the find mechanism built into
zope. - It's not powerful enough for this.

Another: Your design shouldn't have relied on something that would
change. - Well, it happens, now how do I fix it?

A secondary question here is, what about "software configuration
management" and zope?  What if I need to return to an exact version of
my web site for testing a certain bug that's now cropped up at a
customer site.  What's the easiest way to automate keeping old
versions around without having to roll back my current changes.  That
is, without using the built in versioning?  (Sorry, CVS *is* more
powerful in some cases)

Message-ID: <Pine.GS4.4.21.0003051530570.6405-100000@jeeves.stud.ntnu.no>

Zopistas,

I have a small problem here regarding uploading of files. We're setting up
a site where people can upload their MP3 files. We've tested everything on
our site, and everything seemed to work fine - until people started
uploading with modems.

They get timeouts, server not found etc. after around 5 minutes of
uploading. First we thought that it might be because of our proxy setup
with apache or - less likely - the external python method that handles
the file, but when I dug out my old 14.4Kbps modem and tried uploading
a 4MB file directly into Zope at port 9090, I got the same errors.

Is there any kind of timeout settings in the ZServer I can tweak?
Or is there something else going on?

Please help! This is very frustrating, as 90% of our users are modem
users...

Thanks in advance,


Alexander Limi
http://mp3.no


For reference, our setup is as follows:

We run an apache server which forwards all requests to mp3.no:80 to
login.mp3.no:9090. In other words, we use apache as a proxy for the
ZServer. When we try to upload a file from our own computers (10Mbit
network connection), all is fine and dandy. But when modem users try, or
if we try with extraordinarily large files, we get the following error:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST
/artists/testartist/testtrack/add_mp3.
Reason: Error sending from remote server.
Apache/1.3.9 Server at mp3.no port 80

Well I am not a Zopeguru by far, so the only idea I have is that in the
worst case you can always use ftp to such the stuff out of zope, then edit
it, then push it back into zope with ftp.

Well this is really something ftp should work for; making backups. ;)

NS (4.72) goes up to I guess 40 MB or so in worst case here. Just restart
it every day and it should be fine. Also, RAM is cheap (ok not as cheap as
it used to be a year ago, but anyway), so make sure you have 128 MB of ram
or more in your machine.

Mozilla is way cool, but it's still alpha so use at your own risk. I found
it is almost, but not quite, ready for real use.

Hello, 

we have some strange problems with the "SiteAccess"-Product. We are
building up three web-applications on one Zope-Server and three different
domains. Everything works fine with the "Site-Access" but if you have more
than 5 requests at one of the sites the speed gets very slow and you have
to wait about 3-5 and more seconds to get back a simple dtml-document.

We made some tests with the __no_before_traverse__ in the url and found
that there isn't that speed-problem if we access the documents direct
without use of the virtual-hosting.

Has anybody the same problem or an idea how to solve this ?

on win2k i used to use InternetExplorer 5 , but it is
incredibly annoying when the backspace-key is also the hotkey for
'back'; i guess you can see what problems might arise
from this when you accidentally unselect the textfieds when
deleting text, and press backspace a couple of times and end
up 3 pages back in history..

I have found Opera 3.6 to be by far the best browser for
zope-management. It is quick, lightweight, and usable with
full keyboard-access, but it costs money, and allegedly the
linux-version stinks (haven't tested it myself)

Hi Petr,

I found the solution to your problem:

Zope here behaves different, depending on if it's running in normal or in
debug mode ("z2.py -D"). The deb package start up Zope in normal operation
mode, while the binary release's start script starts up Zope in debug mode.

When used in debug mode, Zope appearently doesn't cache extensions,
therefore you don't need to tell it that the module has changed. In normal
operation though, it seems to cache them, so that you have to "edit" the
method to tell Zope something has changed.

As I said, I guess it's a performace question and therefore an intended
feature. At least it's no bug in the deb ;-)

Actually, that isn't quite the point.  He isn't actually arguing 
for AOLserver's superiority over every other system, and somewhere
(but I can't find exactly where) he suggests instead:

     Your development technology doesn't matter.

I wish more managers knew this.  You can build interesting
applications in Zope.  You can build them using Java servlets, or CGI,
or WebObjects.  No tool is going to magically solve all your problems,
and solving them will require familiarity with your tools, hard work
and careful effort, no matter what you use.

We had a manager here who was quite enamored of Java, and early on we
wrote some stuff in Java servlets.  He viewed our Zope work as just
stopgaps on the way to Java code that would carry us into the
long-term, but every time I asked "What problem would be solved by
rewriting all our Python code into Java?", there was no clear answer.
Unfortunately, far too many people in business computing follow
a similar management-by-white-paper-and-press-release style.

Similarly, Greenspun argues that you shouldn't re-invent databases; it
would require a tremendous amount of work to add to your home-grown
system all the features that existing databases have -- fancy query
optimization; storage across several devices; on-line backups;
federated operation; etc...  So use an existing system; Greenspun's
preference is Oracle, but he doesn't argue it like a law of nature.

No, you're not wrong; I did have this problem.
Adding /usr/local/lib/python1.5/lib-dynload to LD_LIBRARY_PATH makes
everything behave much more sanely.  :^)  I wasn't able to import
standard python modules (like socket) before, now I can.

And yes, this was a problem with my basic python installation, but
since I'm only using Python to run Zope, I hadn't noticed.

Unfortunately, this doesn't make things better.  :^(  When I run the 'start'
script, I still get the same error:

$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

PyImport_ImportModule: referenced symbol not found


Here's the part I don't understand.  I started stepping through z2.py (isn't
open
source wonderful?!), and trying the import commands one by one in a normal
Python interpreter.  They all succeed, including the one on line 436 which
resolves
to "import Zope".  Yet it doesn't work from within the 'start' script.

Oh well.  I just verified that I can set up Apache+FastCGI+Zope on my
Solaris2.6
box just fine with the binary distribution.  Am I correct that I should be
able
to set up FastCGI using a TCP socket that isn't localhost, and therefore be
able
to run Apache on our 2.5.1 box and Zope on a 2.6 box?  This would let me get
started
using Zope while I figure out how to install from source at a little more
leisure.


Thanks for all your help,

Not a stupid question, and not simple, either.  There are two ways to do it,
and choosing one over the other can be difficult.

1. Store the absoulte_url() of the referenced object, and run this through a
dereferencing method whenever you want to grab it.

Advantages:  If you really want a reference to a *location*, as opposed
to a specific object, this is the way to go.  That is, if you might delete
or
move the object, replace it with another one with the same name, and
expect the reference to refer to the new object, do this.

Disadvantages:  If you expect the reference to follow the object around
if it's renamed, don't do this.  It has to climb up the path to the object
instead of just grabbing it directly

2.  Store the object as an attribute of the referencing object.  This has to
be done (I think) from an External Method, since you *aren't* setting a
property.  You do something like "self.fooref = self.path.to.other.aq_base"
which DTML doesn't allow.

Advantages & Disadvantages: The inverse of #1

Architectures like Oracle with Vignette running atop it are very

Yes, it's a shame, because this model introduces yet another way where
you have to partition your "cloud".  It shouldn't matter what processor
or network gets added to your website "cloud".  Just keep throwing
capacity into the cloud.

Existing scalability architectures have such a schism along the
three-tier boundaries that it takes wizards to implement and operate
them.  Making them, obviously, brittle and prone to problems.

It will certainly take some time.  But obvious things can be solved as a
higher priority.  Since scalability means different things to different
people, though, there isn't One Answer.

I don't feel that advances in Python are absolutely required.  Apache
doesn't have a threaded model (before v2), and if Zope could dish out
requests like Apache 1.x, everybody would be awfully happy. :^)

This begs the question: how fast is fast enough?  These stupid PCWeek
tests, that give MTS a higher performance score than WebObjects because
it claims to do 4,000 requests/sec vs. 2,000 requests/sec, are just
ridiculous.  At 150 requests/sec, you're talking about the top one
percent of websites on the Web.

The other worry is that these super-freaky Python advances will require
cooperation from the app developers to keep the train on the tracks.

Again, I'm not so sure this is the big answer.  I don't think there's a
lot of evidence that Medusa/ZServer is the primary bottleneck.

Yep, this is ultimately an attractive architecture.  Particularly when
you pour all three tiers (presentation, logic, data) into it, you get a
single facility for scaling and distributing all three.

Right, though I'd encourage you to instead speak in terms of the goal,
rather than the solution.  Is the goal here to solve the 2Gb problem on
Linux/x86, to "limit corruption", or is it to do resource accounting on
a per user basis?  As Jim has pointed out, if your goal is the latter,
you won't get there -- user data can still appear in global things like
catalogs.

Jim's counterproposal, which he claims is easier than doing accounting
across separate Data.fs files, is to finish putting accounting hooks
into the object database.  Whenever a user exceeded their capacity (no
matter where the object), an exception would be raised.  This would
probably require that people be able to do their own packing.

I gotta admit, I'm awfully intrigued by this.  It is the kind of thing
that is _seriously_ compelling vs. other architectures, where you have
to keep on-disk quotas for presentation and logic, and in-RDBMS quotas
for data.

Still, the point is, make sure you speak in terms of goals first.

Doubt it.  There's still so much more, such as data scalability (vs. raw
performance).  As for the latter, we at DC _still_ need to make raw
performance go up.

Personally, I think a very smart caching system (where subtemplates are
pre-rendered in ZServer and know when the objects they depend on have
changed) is a huge win for a significant portion of high-load
situations.

Right.  Does this, though, limit them on the platforms you run on
because of assumptions in the threading model?

Right.  But again, this begs the question: what is a "nice site"?  What
if the goal of a "nice site" could be met w/out the disruption of
rearchitecting Python?

Is a "nice site" 100K hits/day?  A million hits/day?  Ten million
hits/day?

This steps into the next part of the problem.  To date, few in the Zope
community has been willing to publish any numbers for highly-traffic'd
sites, despite pleas even from our board chairman.  Perhaps that means
there aren't really any sites where Zope's limit has been reached?
Probably not.  But why are people so reticent to go on the record with
their hit logs?

But it _does_ mean that, until folks are willing to come forward and
provide numbers and test conditions, that we'll be working without a
map.

Subject: [Zope] Python equivalent of dtml-with?
Message-ID: <4.2.2.20000306100755.00b7bc90@saladin.aisys.com>

I'm writing an external method in Python which is going to be used to 
create new instances of a ZClass that I've written.  In my normal DTML for 
object creation, I would do something like this:

<dtml-with "ZClass.createInObjectManager(REQUEST['id'], REQUEST)">
    <dtml-call 
"propertysheets.instanceProperties.manage_editProperties(REQUEST)">
    <dtml-call unindex_object>
    <dtml-call "manage_editCataloger('MyCatalog', REQUEST)">
    <dtml-call index_object>
</dtml-with>

I've got an external method written which is able to create a new object by 
calling the ZClass.createInObjectManager method.  However, I'm not sure how 
to code up the code contained in the dtml-with block using Python.  I 
suspect that I could get things to work for the example above with 
something like this:

(self is the product containing my ZClass definition)

newobj = self.ZClass.createInObjectManager(REQUEST['id'], REQUEST)
newobj.propertysheets.instanceProperties.manage_editProperties(REQUEST)
newobj.unindex_object()
newobj.manage_editCataloger('MyCatalog', REQUEST)
newobj.index_object()

However, I'm interested in knowing how do code up stuff in Python which 
would take into account acquisition.

Thanks.

(AFAIK, the ObjectManager (base for folder) uses this mechanism too.)

Was just wondering, why the 'aq_base' part is required ? What could go wrong if
I just had self.path.to.other ?

Subject: [Zope] Refactoring Question
Message-ID: <4.2.2.20000306104328.00b75dc0@saladin.aisys.com>

I have a DTML method that I would like to refactor but I'm unsure of the 
results I'll get.  In one of my products, I have a ZClass_add method which 
has code which does something like this:

<dtml-with "ZClass.createInObjectManager(...)">
     <do something>
     <do something else>
     <dtml-call unindex_object>
     <dtml-call "method_editCataloger(...)">
     <dtml-call index_object>
</dtml-with>

What I would like to do is yank all the content out of the <dtml-with> 
block and put it in its own method.  I'm thinking that I would like the 
method to live in my product folder, but I'm open to suggestions.  The end 
result would be something like:

<dtml-with "ZClass.createInObjectManager(...)">
<dtml-call initObject>
</dtml-with>

and the initObject method would be contain

<do something>
<do something else>
<dtml-call unindex_object>
<dtml-call "manage_editCataloger(...)">
<dtml-call index_object>

My first question is, if I create an initObject method in my product 
folder, if I call it from within my dtml-with, will it execute exactly the 
same way as if it were included inline or would it somehow lose the fact 
that it was executing in the context of the "with" object?  I'm thinking 
that the "with" information is put on the namespace and the namespace will 
be available with my initObject method is executed, but I want to confirm 
that my thinking is correct.  Alternatively, should I define my initObject 
as a method of the ZClass itself rather than defining it in the Product folder?

Thanks.

There is a "deprecated" way of doing it, but the thread got off track
without a real answer (the "right" way). The "deprecated"  (the

ZScheduler. It works like this:

In __init__.py module:

# use the old method to set the icon for the ZSchedule object

In class definition.

Subject: [Zope] Authentication - login/logout
Message-ID: <38C3DBD4.A31D2482@ep.newtimes.com>

Does anyone know how to logout a Zope user?
Basically I need to be able to force an authenticated user back to the
'Anonymous' user
programmatically. (when someone presses a logout button, etc.)

Also, how can I change the message text in the login popup window?
Currently it says something like, "Enter username for Zope at
foo.bar.com:"
I would like to be able to modify this depending on where someone is
logging in.

I'm trying this on SunOS 5.5.1, and am getting more less the same
results. See my other article [Problems Installing Zope]...

I have tried adding both the python dynload directory, and even
the Zope/lib/python directory to LD_LIBRARY_PATH, both of which
are no help.

The error I get is a little different:

File "/new1/misc/Zope-2.1.3-src/lib/python/ZODB/__init__.py",
line 85, in ?
  import sys, ExtensionClass, TimeStamp, cPersistence,
Persistence
ImportError: No module named ExtensionClass.

As mention somewhere in this thread, this all stems from line 436
in z2.py :)

Any ideas?

   Strange. Just a check: you wrote '-appConnTimeout 0', aren't you ?
mod_fastcgi is case sensitive (or at least it seems so at the first glance at
the source).

   No, they are only used to report to the webserver. As stated there,
mod_fastcgi doesn't even ask for them.

This is true, he doesn't necessarily argue for the superiority of
AOLserver vs. the world, and that is not what I said either. However, he
strongly advocates for AOLserver, which is fine it is good work. But he
and others who follow have also advocated against extending AOLserver
for tools other than Tcl/ACS. He says, after all, what for?

This is true, but it isn't wrong to want to do your job with a tool you
enjoy. In the event that there are multiple qualifying ways of doing a
job within reasonable means of quality, I think a tool you like and
enjoy would potentially help and enable productivity. There is not
necessarily any magically programming language or tool. However, some
are better than others. Programming well, requires effort and work.

Because something requires effort, even tremendous effort doesn't mean
it isn't worth it. Because something may duplicate features of another
product doesn't mean it isn't worth it. Linux did all of this.
Tremendous work and effort to somewhat duplicate available software. At
some point the efforts which could be perceived as a duplication of
existing software may at some point supplant and exceed the currently
available existing systems. Subsequent versions of many existing
software packages can also fall into this same description of tremendous
effort, to duplicate the features of existing software. But this is
generally for a reason. Some times to improve certain things,
performance, add features, interoperability, portability, etc. I'm sure
Oracle has done this. I'm sure Philip has.

In his forum and other writings Philip has openly argued against most
any potential competing database to Oracle. In his argument he believe
the price of Oracle isn't/shouldn't be a problem. However, to many
people it is. Even though his webserver of choice is db agnostic, his
software ACS isn't. It is very much hardwired to Oracle. Talk to the
people involved in the ACS port to PostgreSQL.

Any advancement of technology will come at a price of tremendous effort
and duplication of current capabilities and features. Sometime it's
worth it, sometimes not.

Philip is right on many of his points. How much has software really
advanced from the capabilities in Lisp from so many years ago? Very
debatable.

As I said his book is a very good read, great material. I like many of
the business ideas and practices of ArsDigita. I have populated my
library with many of his book suggestions.

I have absolutely nothing against Philip, ArsDigita, AOLserver, ACS,
Tcl, etc. AOLserver/ACS is a great tool and toolset. However, in the
discussion of comparing AOLserver/ACS (really ACS) to Zope it basically
boils down not as much to features but to design/architecture of each
tool and scalability. Some people will prefer the ACS way over the very
OO way of Zope, some the opposite. If you are agnostic on such, then
scalability may become an issue. AOLserver/ACS and Zope scale
differently. Philip has a distinct view scalability. Farms, clusters,
no. Single machine, multi-processor, yes. Database == Oracle (his other
uses were also big $$$dollars). Hence scalability == $$$dollars.

AOLserver/ACS currently scales better than Zope. Zope may not currently
be the best choice, or a choice, for Amazon, Ebay, etc. But I think it
can someday. Because Zope is reasonably db agnostic (it does like
transactions), it may be a better solution for many people than ACS
since it is tightly linked to Oracle. If your money and data is
somewhere else you would have to port. In their forum I made comments
that it would be great if ACS were decoupled from it's specific database
dependency. The db connectivity could be abstracted and an appropriate
database api could be created. This would enable other database users to
use ACS. No interest from ArsDigita. Instead there are various peoples
rewriting ACS for their db of choice. As far as I know all hardwired. :(

There is definitely room for both to be successful, and others like
Enhydra. Then there would quality choices for users of various
backgrounds and personal preferences.

There is most definitely a give and take among the choices out there for
languages, webservers, app servers, etc. As for me, when surveying the
landscape from my world view and perspective, the other options
primarily potentially beat Zope "currently" in scalability/performance.
But for me Zope won other areas. I like Zope, I like ZODB. If I don't
have to use an RDBMS, I won't. However, I do hope for ZODB to improve to
the robustness and scalability of the RDBMSes. For some uses it is.

As I read the paper today and see 1 ghz Athlon machines becoming
available, Zope horizons are looking better. Go Moore go. :)

Subject: [Zope] Comparing "unsized objects" and strings
Message-ID: <38C3ED35.C507DF33@newopenness.de>

Hello all,

I have a little problem. I know where it is, but not how to solve it :-)

I have a DTML document:
---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- aid comes from the result of the externalMeth -->
</dtml-in>
---snap

Okay, no problem so far. But when I want to compare the value to a
parameter I have given to the document via a <FORM>:

---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- Okay, works fine of course -->
<dtml-if "aid == param">
Hi there!
</dtml-if>
---snap

The expression evaluates always to false. I have traced the problem back
with an external method ("<dtml-if "equals(aid, param)">"). When trying
the "len" function on both variables, "param" is not a problem (it's a
string from the the <FORM>), but "aid" complains that it was an "unsized
object".

How do I compare them?

Thanks in advance
  Christian

hmm .. untested:

<dtml-if "_.str(aid)==param">

_.str(aid) should return a string presentation of aid.

Woohoo! Absolutely. :)
However, if a multi-threaded/multiprocessor capable Python were
available to embed into AOLserver then it seems to me that the improved
performance would be transparent.

This is true if the requests are evenly amortized throughout the 24 hour
period. Unfortunately they aren't. For me fast enough means that your
machine is not maxed out (or croaking) when handling peak loads. Your
visitors handle the speed/latency well. It is all very relative.

I agree. I was just hypothesizing. I would generally prefer to keep with

True and maybe not. However as Zope pushes into heavier trafficked
environments who knows. But we'll take whatever speed gains we can. :)

What I like about this is the capability of distributing your work load

Actually not necessarily either. I don't want data corruption, so if
that's an issue it will need to be addressed. Say for example I have a
very large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5gb directory which is reasonably stable
updated monthly.
ZAuto/manufacturers isn't so large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.

My example above doesn't fit into this situation, at least as far as I
can tell. There are no user quotas or explicit restrictions.

I have somewhat lumped raw performance and scalability together. In many
ways they are hard to separate. I agree a smart caching system would be
nice and a tremendous boon to performance. In Philip's writings, he
believes that performance is best when the entire db resides in memory.
Sometimes that is not possible. However, if you cache the most often
accessed parts you reap tremendously.

I don't know, I am not a threading expert. However, with AOLserver, I
believe that stayed with the POSIX model. So if Python was such it seems
it wouldn't be a problem in most cases.

Yes, this is a very subjective area. My original problem with Zope's
scalability and what would scare me with a site is the inability to
throw hardware at it. ZEO didn't exist then. The question exists though
is if a Zope based website was getting 1 millions hits a day and gets
Slashdotted or some other such phenomena and in a few weeks or months
grows to 5 or 10 million, what are their options within Zope? Where will
the bottlenecks come from? Can they throw hardware at it? What if
tomorrow my "Slamazon" bookstore went online and was an instant success?

It does, but the "string" is still an unsized object. 'Scuse me, I
thought Python is not strong-typed?

I'd have thought someone would have answered you by now. Have a look at the
Zope Quick Reference:

  http://www.zope.org/Members/ZQR/

Also, looking over the doc/CHANGES.txt file can give you lots of clues about
new features that may not yet have been documented.

If I am understanding you correctly, you should have a look at Loren
Stafford's ZScheduler. Download it from Zope.org, and look at the code for
the ZEvents. They are catalog aware, and override manage_afterAdd, then call
the superclass method.

Hi,

What versions of Zope (probably 2.1.4) and what versions of MySQL work together?   I have tried unsuccessfully to get MySQL to work with the the MySQLDA using the latest stuff.

     Keywords:  Management Interface 

 Submitted by:  Dylan Jay djay@innocent.com
-------------------------------------------------------------------
 When I create a ZClass with my own management methods they 
 will by default use standard_html_header etc. This doesn't look 
 like the standard management interface. I think we should have 
 a standard way of making all management interfaces look the 
 same.  In fact this should be able to be changed for any subset
 of management interfaces so you could for instance change the
 way the standard zope interfaces look.

Dang!  Another "lead zepplin" topic!

Perhaps everyon was holding off because they expect that the
management interface is merely a short-term, necessary evil, to
be replaced RSN by:

 * The "Zope Studio":http://www.zope.org/Resources/Mozilla/index_html
   project, which uses Mozilla's way cool XUL technology to build
   "Zope-aware" chrome in the browser?

or:

  * The upcoming Model-View-Controller
    "re-archictecture":http://www.zope.org/Resources/Mozilla/ZWiki/ModelViewController 
    project, which works to divorce the HTML presentation (the 
    "view") from the underlying Python objects (the "model");
    this is enabling technology for ZopeStudio, the 
    "ZIE":http://www.zope.org/Members/johanc/ZIE/ZIE-demo cognate
    for InternetExplod^Hrer, a wxPython and XML-RPC client like
    the one Amos Latteier
    "demonstrated":http://www.zope.org/Members/Amos/XML-RPC 

or:

  * The "Portal Toolkit":http://www.zope.org/Products/PTK, which
    replaces much of the current management interface with new
    "wizard"-based configuration tools.

I'll close by thanking Dylan Jay for suggesting the topic, and
for his thoughts on potential solutions.

Keep those cards and letters coming!

     Keywords:  ZClasses 

 Submitted by:  Tres Seaver tseaver@palladion.com
-------------------------------------------------------------------
 When building a Product using ZClasses, I often want to create
 a "root" ZClass, which the manager will create in a normal
 folder, and which will then expose the Product's other ZClasses
 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel
    +- FooProduct
       + FooItem_add_permission
       +-FooRoot
         +- FooItem
         +- FooItem_add

       + FooRoot_addForm
       + FooRoot_Factory

Hi everyone,

I'm asking this question again because I still haven't been able to work
it out for myself. I'd like to have a button or link on a page that, when
pressed, presents the user (the Manager actually) with a dialog to upload
a new version of a file object that's in that directory. I presume that
the manage_upload method would do the trick, but I can't figure out how to
use it.

The file object I want to update is called 'Bookmark.htm'. I'm trying to
make it easy for our school librarian to distribute our standard bookmarks
to all of the machines in the building.

ZCache caches method results.  It's kinda broken and not very extendible. 
I'm writing GenericCache as a replacement, but it'll only be finished when I
have enough time.

Subject: [Zope] Listening on specific interfaces
Message-ID: <7502CAC76F59D211B0090000F8662FA305F43EE7@ap3expr3applge.appl.ge.com>

All - After bringing up a logical interface (hme0:4) on physical interface
hme0, Zope will not work if I try to use a value of 80 for the HTTP port.
Netscape Enterprise Server is running on this same box and is already bound
to the physical interface hme0 listening to port 80.  My guess is that Zope
is not really binding to the virtual interface, but is trying to bind to the
physical interface and thus it is conflicting with NES.  The error follows:

$ ./start -a 3.130.232.27 -w 80 -f 8021 -m 8099
Traceback (innermost last):
  File "/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/z2.py", line 493, in ?
    logger_object=lg)
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/http_server
.py", line 552, in __init__
    self.bind ((ip, port))
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/asyncore.py
", line 205, in bind
    return self.socket.bind (addr)
socket.error: (13, 'Permission denied')

3.130.232.27 = hme0:4

If I specify an HTTP port that is not currently bound to the physical
interface (hme0), such as 1234, Zope starts up properly.

How can I force Zope to bind to logical address 3.130.232.27:80 so that it
no longer conflicts with NES?  Is this even possible?  I have a few Zope
apps. that I would like to bind to different logical interfaces on port 80
so that I can use different hostnames.  Additionally, I do not want the
user(s) to specify a port in the URI.

Thanks,
-Brian

I have Oracle 8i for Linux. When I tried to compiled the ZOPE DCOracle
interface, I got errors about the missing library 'netv2' which it seems
is supposed to be part of Oracle. Does anyone know why I might not have
this library or how I can get my hands on it?

LoginManager is a thing that aims to replace user folders.  It accepts
plugin User Sources (which know about users) and Login Methods (plugins
for different methods of logging in -- things like Basic Auth, Cookie
Auth, etc).

You can get it from the ZopePTK CVS. (It's useable without PTK, though
-- there's nothing PTK-specific about it. It's just that it's
particularly useful for PTK)

LoginManager currently comes with a default User Source called Generic
User Source (GUS), that is a GUF-like roll-your-own system.  It uses
GUF-compatible methods (userExists, userRoles, etc), so converting any
GUF-using site to a LM site should be pretty easy.  We plan to write
another User Source that is a simple ZODB-based plugin that parallels the
current plain User Folder.  Other existing User Folders (etcUserFolder,
etc) could/should be converted to user sources. 

One advantage is that you can have more than one user source, so if you
need to have employee logins from your corporate LDAP directory and
customer logins from your Oracle database, you can do that. The
implementations of each can be completely separate and reuseable.

Another advantage is that there is no longer the "n times m" problem of
login methods.  If someone writes a PostGresSQLUserFolder that does SSL
client certificates, there's no easy way for you to use that SSL client
certificate capability with etcUserFolder.  But with LoginManager, if
someone writes a SSL client certificate Login Method and someone else
makes an etcUserSource, they automagically work together.

There are some other cool features too, and more coming.

By the way, for those of you who were at IPC8 and were confused by the
RIPP Patterns talk (which is everyone who attended, I think ;->),
LoginManager is so far a good example of at least the RI part of it.

LoginManager is the Implementor for users (it's just called acl_users
instead of I_User :->). User Sources are really Racks. 

The "things from different authors automatically work together" nature
of LoginManager is exatly what RIPP is for. Now that we have an example,
maybe we can try to explain it better and get other people using it for
other things :-)

Despite your following (very good) points, this is not true.  It leads
to conclusions like "Perl is just as readable as Python", "Let's just
use C, it can be made as portable as Java", "We should use Lisp for
this 3D first-person shooter, we just need a better algorythm than
previous C implementations."

A better way to phrase this is:

	Your development technology is only one piece in a larger
	puzzle.

I've recently switched a rather large project from Java to Python --
throwing out nearly 2 years of work in the process -- and I have
noticed an immediate increase in development speed.  Changing
development technologies was a GREAT idea; but only because it was
considered within the framework of the developers we had, the skills
they had, and the relative advantages of both frameworks.

The project had a high dependence on lists and hashes.  Changing to
python increased performance (all these data-types are native in C, in
python; profiling our code shows that it spends most of its time
inside java.util.Hashtable), scalability (Java has lots of hard limits;
a max of a few thousand interned strings, 32M of RAM per process unless
you start diddling command-line arguments, and GC gets unbelievably
slow if you do that), reliability (the JVM on Linux is buggy; python is
pretty robust if you're not using any crazy native modules ^_^), and
last but not least, we get the source to our tools so we can improve
them ourselves.

Certainly, nothing is a magic bullet or a panacea that will make all
your development problems go away, and I doubt that anyone reading this
list believes that.

Coincidentally, if you are, and you do, I have a GREAT WAY to MAKE
MONEY FAST with NO INVESTMENT!!! It is NOT MLM!! ;-)

This is a great point.  Considering the technology within a coherent
whole is EXTREMELY important, and the view of some managers that
something is just going to be a panacea that resolves everything is
depressing.  It's not limited to development technologies though -- it's
"employee empowerment", it's "diversity training", "thinking out of the
box"... bad management transcends the boundaries of space and time =)

In my experience (I admittedly haven't read this particular article)
Greenspun's advocacy of Oracle and WebDB is near-rabid and biased
toward extremely high-end applications for people with lots and lots of
money.

What you're referring to as "re-invent"ing, by the way, is referred to
by some as 'innovation'.  However, I will agree that the time to do
that is not necessarily when a large project is nearing a deadline...

Finally, I think Zope is a great tool, and for some applications (making
a Slashdot clone, for example) it DOES have the kind of killer advantage
that can make it worthwhile to switch lots of work in another system to.
 It all depends on what's appropriate though -- if, for example, your
site needs to have access to AdaBase, I don't know if Zope is the best
way to go.

I have actually seen projects for which CGIs written in C++ were
unquestionably the best choice.  Examples like that are rare, but they
do exist.

Hi,

I'm running Zope 2.1.14 on Redhat Linux 6.1. I would like it to start 
automatically when the computer boots. I'm looking for a workable rc script for

I tried the script found on the How-to: Installing and Upgrading Zope 2.X.

You didn't say what problems, if any, you are having, so I'm just going to
take a shot in the dark.

By choosing a DTML Document, clicking on the Upload tab, and viewing the
source, I believe you need something like:

<FORM action="manage_upload" method="POST" enctype="multipart/form-data">
<INPUT type="file" name="file" size="25" value=""><BR>
<INPUT type="submit" value="Change">
</FORM>

Make sure you don't leave out the enctype attribute or things will be
unhappy.

Let me know what, specifically, doesn't work if you continue to have
problems. I'll do my best to help.

Out of curiosity, are you running (lauching) Zope as root? The lower ports
(below 1024?) are privelaged on UNIX, and require root permission to bind.
Higher ports, such as 1234, are not; anyone has access to port 1234.

We have a Solaris 2.6 box here running Zope 2.1.4. We launch ZServer with
the -a parameter specifying our interface, and it works like a charm. I
suspect this is not interface related.

Look at the management form that you see when you create a File object, and
do what it does, only in the context of your user interface.

Thanks Jeff...that was the problem...all of my Zope instances until now have
been started by uid zope.  Rather stupid mistake, but a learning experience
nonetheless.

Thanks again,         -Brian

Anywhere inside the "main" folder, you should be able to write <dtml-var
expr="sub.message">.  Outside of "main", you would have to write <dtml-var
expr="main.sub.message"> or possibly <dtml-var
expr="f1.f2.main.sub.message"> if "main" is in "f2" is in "f1".

If I'm understanding the problem correctly, try:

Wade, the best you can do with basic authentication is to do something
like:

<dtml-raise Unauthorized>
 You are logged out.
</dtml-raise>


However, if the clicks cancel on the login box that pops up (there's no
way to prevent it from popping up), he or she will still be logged in.

Use cookie-based authentication if this is a constraint.

You can use the environment variable Z_REALM to change "Zope" to
something else in the login box text.

This looks right.

Acquisition is built into Zope objects; the only time you should ever have
to "take [it] into account" is if you are trying to acquire an object with a
non-identifier Id, or whose Id is stored in a variable.  In these cases
"anobj.aq_acquire('foo.html')" and "anobj.aq_acquire(fooname)" should do.

Yesterday I had to restart NS no fewer than 5 times, to prevent the
'swap-to-death' situation.  I have 96M in my machine, and i've been careful to
eliminate all extraneous tasks to reduce memory usage.

Yes, memory is cheap, but to get this box to 96M (from the original 32) took
quite some wrangling, since it seems ordering more RAM here can have at least
an 8 day lead time, amongst other things.

As a programmer myself (ZOPE is like a holiday :) I know that memory leaks can
be easy to code, and tiresome to track.  But in an application as large as
Netscape, I would hope for slightly tighter quality controls, and a little more
coding discipline.  There are some fairly simple guidelines you can follow to
write "zero resource loss" programs.

Yes, I looked into Mozilla yesterday.  However, I discovered it will ONLY work

don't have ANY other apps using it.

Greetings,

I have used MySQL 3.22 (Stable) and 3.23 (Development) with Zope 2.0.1 through
2.1.4.

I am currently using them with the ZMySQLDA version 1.1.3, along with MySQLdb
version 0.2.3.  There is a very good howto on installing these.  I have
recollections of compile problems on my first attempt, but it turned out I was
tryring to compile something that was obivated by MySQLdb.  So, follow the
instructions carefully.

Subject: [Zope] Frequent Zope Restarts and GUF authentication
Message-ID: <m3k8jf4svq.fsf@wacko.pdx.net>

I have a server that is being run in production mode without the
-D flag.  The server processes die after about two hours.  I haven't
seen the actual crash yet nor have any users complained about error
messages.  I know the server is restarting because the Control_Panel
tells me so.

Well, the real problem here is that since my site is protected with
GenericUserFolder in cookie mode, GUF's cache gets wiped when the
server bounces.  This forces my users to log in again.  

Two questions, 
  Any guesses as to what's causing the mysterious restarts?

  Any idea on how to resolve the GUF problem?

Zopists,

Has anyone else noticed that the endmail tag will sometimes not send a

In this context 'cache' is the in-memory cache of Persistent objects
(most objects in Zope are persistent, for example, just about everything
you can add or manage in Zope is persisent).

Obviously, it's not very good performance to read and write all objects
to and from the database everytime you use them.  Therefore, there is a
cache to speed this up.

The 'target' is the number of objects in the cache.  Note that this is
not a very hard limit, ie, if you set it to 10, it will let you load 10
tiny objects or 10 huge ones.  Or 10 of mixed size.  Experimenting this
this value and watching how much memory Zope consumes is a good exercise
in performance tuning.  Note that there is NO magic value here, you have
to play with it.  Keep in mind that the default is very conservative,
you can definatly start playing with it in the up direction (unless your
running on a 386 with 16MB of RAM...).

I am also trying to get MySQL running with Zope 2.1.4.  I'm trying to follow
the HOWTO by "alanpog."
I got to the part about Expand and Install MySQLDB but I am stuck.  In the
installation README, it says to read Setup.in to verify the paths.  I have
no idea what those paths or for and I don't have them on my Linux system.

Does anyone know what these paths are for and how I can determine what I
should set them to?

I have MySQL 3.22.32, I'm trying to install MySQLdb 0.1.2 and ZMySQLDA 1.1.3
per the alanpog HOWTO

Curtis, what is the really good HOWTO you mentioned?  The one I found is
very brief and isn't helping me much.  Also, where did you get MySQLdb
version 0.2.3?  The latest I saw was 0.1.2.

David, did you manage to get past the Install MySQLdb step?

Thanks,

Eric.

Hi,

Something that seems maybe very trivial, but I did'nt find the solution.

I have a very simple class ItemId (metatype ItemClass) which is only a
subclass of Image and has no property sheet.

When I try to create a new instance I get the following message : 

Error Type: TypeError
Error Value: argument file was ommitted

Here is my addMethod:

.......
<dtml-with "ItemId.createInObjectManager(REQUEST['id'], REQUEST)">
<dtml-call manage_upload(REQUEST['myimage'])

</dtml-with>
......

Where 'myimage' is the name of a field of type file in my input_addForm.
I works fine when I use manage_upload with an Image but not when it is a ZClass
subclassing an Image. Where am I wrong?

Thanks.

Thanks, that sounds like what I'm after.  I don't quite understand why
this is not setting a property.  Can you point me to some documentation
that might help explain the difference?

I guess putting in a little Python is no big deal, but it does break my
ultimate goal of letting non-technical people create new classes of
content.  Is there any plan to add inter-object relationships to ZClasses?

what about the options in fastcgi?  processes in FastCgiServer defaults to 1. 
-maxProcesses defaults to (50)  >-maxClassProcesses defaults to (10)

will increasing these numbers help stop connection refused error?

fastcgi is a like a black box to me, full of mystery, even after reading the
docs.

I hope you got your setup working, Jeff.  Your rewrite rules look
good to me.  But I want to take this opportunity to make a (tested)
alternate suggestion for the rewrite rule.  The above rewrite rule
has the unfortunate feature that URLs like ".../Zopestuff/etc"
match the rewrite rule and get turned into the (not found) path
.../cgi-bin/Zope.cgistuff/etc.  This isn't a problem normally, but
you can perhaps imagine having Zope under a directory with a given
name but wanting another URL with that same name as a prefix
substring to also work (.../news and .../newsimages perhaps?).
I've come up with what I think is a better regexp for use in this
kind of rewrite rule, mostly to avoid the surprise factor of later
having a Zopestuff type URL mysteriously fail to work on me someday:

.../Zope(/.*)?$

which is mapped to

.../cgi-bin/Zope.cgi/$1

The ?$ means that the /<stuff> all the way to the end of the URL is
zero or one time.  So Zope by itself matches, and Zope followed
by a / matches, and Zope followed by /stuff matches, but Zopestuff
does not.

FWIW

If MySQL does everything you need, it is probably the better choice.
GenericUserFolder is more complicated to setup (so it appears better
supported as their are more questions), and exists to support sites
with more unusual requirements.

an acl_users folder only authenticates the sub-tree it is defined in.
If you want AUTHENTICATED_USER available in /home, then move your
acl_users folder into that folder. Your users will not be required
to login if they access stuff that is available to the Anonymous role,
but if they have logged in, AUTHENTICATED_USER will be set.

The problem line is <dtml-if "e">. What I was intending to do is
perform the code if the search result actually returned something, but
this doesn't seem to be happening. What I'd like to do is:

<dtml-if "len(e) > 0)">

But, len() doesn't seem to be defined in whichever namespace the code
is being run in. I tried:

<dtml-call "global len">

before the dtml-if, but this errored out as well. Am I completely
misunderstanding the problem which I'm having?

Thanks.

Good luck. :(

 Browsers and servers are neither required to, nor are (to my knowledge)
respecting any sequence of form fields. Basically, IME, if you need the
data going in somewhere to be in the same order ( a program that expects
certain values in certain a order, for example), have whatever processes
the returned data order it for you.

I've just been testing, to see when the most leaking occurrs.  It's definately
whenever I type in the edit box.  At one point I hit enter, and it grew by over
300K.  As I type, I can watch the size grow.  It's really that fast.

As I type, I am downloading the NS RPMs from RH6.2, which seems to be a few

Much appreciate the effort.

Someone even suggested it might be my Motif lib.  KDE, afaik, catches all the
Motif calls and replaces them with its own widgets.  A workmate running Gnome
checked the same situation, and the memory leaks in just the same way.

scratch another theory.

To use len, try:

  <dtml-if expr="_.len(e) > 0">

It is part of the _ namespace.

You may also be able to achieve the same result (depending on the types of

  <dtml-if e>

Ok, it appears that len() isn't what I want. I was under the
impression that searchResults() returned an object which functioned as a
list, but this wasn't right, apparently. Or maybe it was, *shrug*. :)
Here's my current code, which I've modified a bit for testing
purposes:

<dtml-var standard_html_header>

<dtml-call "setCalendar('valign','top')">

  <dtml-var dprop>

This code generates links as it should. What I'm trying to do though
is, if an object of the Event class exists with an event_date which
equals the current rendered date, I'd like to link directly to it. I can
successfully search for the date using the PTK's search form, so I'm
fairly sure that my issues with the catalog are resolved.

So, what exactly is being returned by searchResults, and how can I
determine whether my search yielded anything, so that I can display a
link to the item?

Not if you do not name them explicitly. The REQUEST.form.items() is a
python dictionary. Keys of a dictionary have no fixed order. You could
sort them if you wanted to, but that would be a computer order, not the
original order in which they appeared.

I had a system where it failed (also silently) every first time after reboot.

I just moved to an external method that used /usr/sbin/sendmail as I did 
not have enough time to start debugging. Telnet to port 25 had just a very 
long (>30 sec) startup time, probably some DNS problem. 

AFAIK Zope does not (for some unknown reasons to me) use pythons SMTPlib 
but has rolled their own smtp interface.

It has also been reported to fail with MS Exchange server, which someone 
fixed for himself by swithing to smtplib. IIRC the patches were also posted 
to zope or zope-dev list.

IMHO the right solution for Zope would be swithing to smtplib, and if there 
are faults then fix them there (and maybe include fixed smtplib with Zope 
until fixes are included in mail python distro). There is no need to invent 
to similar but slightly and differently broken wheels, at least in Open 
Source Software there aint.

Message-ID: <4.2.0.58.20000307085505.00c2ee80@195.60.12.162>

Dear Zopers,

I read Chris McDonough's How To on Gaining Zope Enlightenment by Grokking 
Object Orientation. It raised a few questions in my RDBMS-oriented head. So 
I mailed Chris with these questions but Chris explained he just couldn't 
answer them right now and asked me to post them to the list. They seem very 
basic, very fundamental questions to me.

So here is my email to Chris - If I get any answers here I would like to 
include my questions and your answers in a How-To to help those who come 
after me !

Thanks for any help !

Here's the original email

---------------------------------------------------------------------------- 
----------------------------------------------------------

Chris,
I enjoyed your How-To on Gaining Enlightenment very much. I've been using 
Zope for a couple of months now and I've made some progress - my first 
project has been to use it to give access to established databases over an 
Intranet. Like you I think its wonderful, but like you I keep getting 
stuck. Never mind, with the help of the mailing lists and long hours 
reading books on Python etc I've made progress.
BUT ... (there's always a but isn't there) - no matter how much I read and 
play around with OO - I still don't 'get it'. My background is many years 
working with relational databases on Unix - (and there are thousands like me).
I just don't get the bit about storing data as objects. Could we discuss 
this a bit more and perhaps publish my questions and your answers on 
Zope.org ?? This may help me and the thousands like me.
OK, you create your class of Spam, which has attributes of cansize and 
texture and it has methods that display these attributes. No doubt you 
could add other attributes, such as selling price and develop a method to 
increase the price by a percentage. OK so far ?
Now we create an object (which is an instance of the class Spam) - which we 
call myfirstcan. We can define the attributes for that object when we 
create it or later and we can use the methods defined in the Spam class to 
do so. OK so far ?

What I don't get is how you store and retrieve the objects you create. 
Let's go to a more realworld example - how would you implement a stock 
system using objects ? Let's take the simple table Stock which has three 
columns
Product_code Description Price
and we could enter rows of data into it, for example -
ABC Spluggifier 20.00
CDE Super-spluggifier 25.00

Now if I was writing a conventional database system I would maintain the 
above by defining a program which perhaps prompted the user for the 
required columns (Product, Description,Price) and then I would store the 
users input in a row in a table. Perhaps another program (the price change 
program) would use a stored procedure to allow price change. OK ?
Now in OO terms I see that I could create a class of Stock with attributes 
Product, Description and Price. I could create a method to allow price 
changes. Very neat.
Then I can create an object( i.e a particular stock item) by saying 
something like
product_1 = Stock(product_code="ABC", Description="Spluggifier", Price-"20.00")
Now I can create another object by saying
product_2 = etc
but that is not the way you would do it surely. You would be effectively 
'hard-coding' each product in your system.
Surely you would have a program which did something like
WHILE the user is entering data
PROMPT user for data
VALIDATE data
WRITE data to database
END WHILE
How do you do that in OO terms ?
How then do you search and retrieve an object with a particular value of 
product_code ?
How do you write a program which updates the price of all stock items where 
the product_code begins with AB by 2%.?
Thanks for reading this far. Hope you can stop my head spinning !

Regards

Richard

I'm still having difficulty with this.

I want to add a date to a character string ( dated user comments ) to
store into a sqltable.

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">

The docs say that this returns a date string ( as opposed to a date
object? )

<dtml-call "REQUEST.set('mystring', 'date: '+CurrentDate)">

produces this error

Error Type: TypeError
Error Value: illegal argument type for built-in operation

And if I try this

<dtml-call "REQUEST.set('mystring', 'date: '+_.str(CurrentDate))">

mystring is then 'date:'

I have not obviously researched this in detail (perhaps you may want to)
but I do not believe that the any of the various web rfcs define that
either the client or server should send/expect any form elements in any
explict order, and that if any order is mentioned at all it is probably
'implementation defined'.  The introduction of various CGI interface
libraries for various languages probably munges this even further.  I
would not rely on any consistent order at all coming from any system.

We wrote the sendmail tag before smtplib was written.  At the time there
was no existing standard smtp client library in python.

a sequence of record objects that describe cataloged objects that match
your search query.  The are NOT the actual objects themselves, just
'descriptions' that can be used to refer to the objects (with 'getpath'
as you discovered, or 'getobject').

In your case, 

<dtml-if e> 
    There are results.
<dtml-else> 
    There are not results. 
</dtml-in>

I don't undertand what you mean, you code apears to do this.

BTW, it is much easier for other people (or at least me) to assist you
if they can read your code.  For python programmers, this means
indenting it sensibly.

You can do this, but you must be sure you understand that your object
now references the other object without the Zope framework's
'knowledge'.  This is not a bad thing and happens all the time, but you
should be familiar with what this does to things like garbage
collection, persistent object deactivation, and circular references.

I don't know what you were trying to do before, so I can't answer this.

You mean references?  We've thought about this problem a little and Jim
and I discussed this over Chinese buffet once, I obviously had less of a
clue than him, but I belive the result of our discussion is that there
should be some sort of standard for one Zope object to refer to
another.  The simplest way we could think of is simply storing the
path.  Such as:

attribute = "../../relative/path/to/other/object"

or perhaps:

attribute = '/absolute/path/to/object'

Then when you want the object you ask Zope to resolve that path for
you.  Currently you can use REQUEST.resolve_url(attribute) to do that
for you.

If you're not working on python you can simply set a string property as
the path.

This is how ZCatalog does it (actually ZCatalog uses a slightly dumber
version of this concept, don't ask).  HOWEVER, the lack of any kind of
standard or support for such references in the framework has bitten
ZCatalog (and webdav) in the past, and the decisions we made will
probably come back to haunt us real soon now.  You have been warned.

Hi,
Stephen Pitts <smpitts@midsouth.rr.com> posted a patch that may help you.
This patch replaces the socket-base code with smtplib calls.
The original MailHost didn't work with our Exchange 5.5 server, but after I
have applied the patch it works fine.

Subject: [Zope] copying image object?
Message-ID: <200003071209.AA19294@rsphy9.anu.edu.au>

Hi Zopistas,

A likely FAQ but it's late, I've been Zoping for 15 hours, ZQR 
is temporarily unreachable from Canberra, I can't see straight
and I'll admit it - I'd like to wake up to the answer ...

I simply need to copy an image object (image1) from my
globals folder to within an instance of a containerish 
ZClass.  I toyed with manage_addImage() but couldn't
find a method to get the raw data out of image1. 

Cheers,
Darran.

Subject: [Zope] Tricky usage of string to integer conversion
Message-ID: <000001bf8839$b997a5e0$0b00a8c0@nassau.islands.net>

I am trying to do the following:

<dtml-let x:int="REQUEST.get('prod_config')"
          item="_[REQUEST.get('prod_id')]"
          price="item.price_list[x]">
    <INPUT type="hidden" name="chargetotal" value="<dtml-var price>">
</dtml-let>

The prod_config variable is a number (returned as a string) from a SELECT
list.  The prod_id variable is the id of an object in the same folder as
this method that has a price_list attribute.  price_list is a list of
strings representing prices.

This results in a "Name Error" where Zope cannot find "x".  If I change line
3 to this:

          price="item.price_list['x']">

it fixes the Name Error, but then I get a "Sequence Index must be an
integer" error on price_list['x'].  I would have thought the use of "x:int"
in my <dtml-let> would take care of this issue.  Seems I can't win!

Does anyone know the correct way to do this lookup?

Brian Holdsworth

"dtml-let" doesn't understand type annotations, so you are setting a
variable called 'x:int', which isn't what you want.  You need to do the
integer conversion in Python, like so:

<dtml-let x="_.int(REQUEST.get('prod_config')" ...>

See the DTML reference guide at zope.org for more useful methods of "_".

I think it must be converted by the atoi method of the string module:

so either:

<dtml-let x="_.string.atoi(REQUEST.get('prod_config'))" 
          [rest of your code]
or:

<dtml-let x="REQUEST.get('prod_config')"
           item="_[REQUEST.get('prod_id')]"
           price="item.price_list[_.string.atoi(x)]">

This is the same problem as last time. You must CALL the Date method, not
just reference it. The above line should read:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date()">

Note the use of parens on Date().

Try it for yourself by putting the following in a DTML Method:

  <dtml-var expr="ZopeTime().Date">

You get:
  
  <method DateTime.Date of DateTime instance at 568eb0>

if you do a View | Source in your browser.

It does, if you CALL it.

Here is some code that works:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
  <dtml-call "REQUEST.set('mystring', 'date: ' + CurrentDate)">
  <dtml-var mystring>

Again, you've never set CurrentDate correctly. View the source of the page
that comes back and you will see the problem.

Hope this helps.

It supports it to no greater or less extent than Linux does.  The
standard library defaults to using an int or a long for *seek calls.
The difference is semantic only, as they're both 32 bits on both
systems anyway.  Even if you assume unsigned (fseek is signed), that's
still 4gb, max.

However, on my Linux/Alpha system, a long is 64 bits.  This
effectively removes the problem.

I submit, therefore, that you are not seeing a Linux problem, but an
x86 problem :-)

Why?  This is overkill for what zope is.  Zope is not, in essence, a
web server.  If you want to do strange things like that, use Apache
:-)

Completely inaccurate.  Proprietary software (Please, use the Jargon
file next time you look something up in the dictionary, geez) is
software which is not licensed under a Free Software license.  This
includes Java *as implemented by Sun* but NOT DTML or Free
implementations of XML.

Well, the issue is not really "the language".  The issue is whatever
software implements it.  Anybody can implement DTML, or Java, or XML,
or whatever, and license it however they want.  The question is,
whether this implementation is Free Software, and indeed, it is.

Interesting point.  I myself prefer Perl to Python for a number of

Untrue. Apache's load/stats and Zope's load/stats are different sides of
different coins.

You're implying that Zope has no statistics to export, and that if you
couple Zope with Apache (which you might not want to) then the numbers
that Apache can export would apply to Zope -- and this is clearly wrong.

Thank you for completely sidetracking me and instead choosing a flame
angle for petty word games.

My point specifically was that the mass of mainstream appreciation of
Zope versus a product like Dynamo was specificially _not_ related to
openness. IBM does not open its money floodgates to invest in Linux
merely because Linux is an open technology -- Linux was not the first,
nor the last, not arguably the finest open technology in the history of
IT. It and others do so, and give momentum to Linux, because of money,
pure and simple.

Let me relate a short anecdote for you, about the incident which
triggered this thread. See, my colleagues are currently involved in a
large project for a large company. They are buying Solaris 8 to run
Dynamo. I've made a very strong case for Linux and Zope.

There is, today, only a marginal difference between these two setups,
and that difference is in price: The Linux/Zope combo is significantly
cheaper than the Solaris/Dynamo combo. This has zero bearing upon their
choice, and indeed on most ordinary computer investments for any
company: The cost of buying a computer and licensing the software is
"nothing" compared the maintenance costs and the insurance a big company
needs that their investment is safe. In other words, heavy support plans
and brand names.

And guess what? Despite the fact that both Linux vendors and Digital
Creations offer such support plans, my advice to my colleague and this
company falls dead on the ground.

Zope doesn't have the flashy packaging and sexiness of a product line
Dynamo -- which, actually, I strongly urge you (and everybody else in
this forum) to experience yourself, before you snap back at my again --
and this affects management decisions. Dynamo is exceedingly sexy, and
it boasts the kind of bullshit magic that have management and tech
people alike drooling.

So is it "their problem"? In the end, I don't think so. I think they're
going to be quite happy with Dynamo.

As one of my colleagues pointed out, the problem starts with the name.
(Somebody out there is hyping what they call Linux' next-generating GUI.
And it's called... GNOME. What's wrong with this picture?) I don't care
myself, but I recognize the problem.

I don't claim to be an OO master or a ZOPE master, but I'll give this
a shot anyway and share some recent revelations I have had about OO in
general.

First off, the examples that people always use to demonstrate OO
concepts wind up being more distracting than they are worth.  For
instance modeling a can of spam in OO.  That would be a logical thing
to do, if you were writing a control program for a can of spam.  But
NOT if you were writing a database app!  This, I think is one of the
most confusing parts for database programmers coming to OO.

Second, so if you don't model your can of spam, then what DO you
model?  Well, you model *your data* and if your data is a database,
then that's what you model!  Soo, you create an object of type
"Products_Table" which contains methods to operate on the entire
table.  Then you create objects of types "Products" which contain
methods to operate on the objects.  But since your products can be
many different kinds, you don't "hard code" what kind of product they
are, you just make a generic object that contains generic functions.
If you wind up needing to do something special for a particular
product, *then* you create a subclass of product for that kind of
product that you can use for that.  Ie:  "Delicate_Product" might be a
subclass of "Product" that might have a special some special methods
for dealing with products of that type.  Something like "find" should
be a method of the table that returns an instance of your product.

So, your loop becomes something like this (pseudo code that looks like
c++?):

while(sData = Input.Read())
{
	MyProduct = new Product(sData); // object init's itself
	if(MyProduct.Validate())
	{
		MyProduct.Write(Table);
	}
	delete MyProduct;
}

Is there a way to upload more than one file or image at once?  It seems very
cumbersome.

thank you!

Hmm.. are you sure you are starting Zope as a priviliged user, like root?
Zope can only bind to port 80 if started as a priviliged user (it will not
run as a priviliged user, rather, it will, by default, switch to 'nobody').

The permission denied error is clear pointer in this direction.

Lynx does frames just fine. It lists them as hyperlinks. Just select the
second one, and you'll be amazed how much you can do with Lynx and Zope =)

This is because:

1/ MailHost doesn't integrate into the transaction mechanism all that well
(patches accepted =))

2/ Email is inherintly an unreliabale form of data transport.

Hi. How's Jim getting on with this? Apologies if I missed something

Hi everybody,

although this may have been discussed several times:

I added a multiple property to a class, but when I call the instance's
property sheet from the management interface, I get an Type Error,
whenever I did not chose anything from the selection box. That is of
course ok, because there is no property defined within the instance if I
did not select anything. (getProperty(id) fails on None)
How do I create an "empty selection"?

Thanks for your help

BTW: <dtml-call "REQUEST.set('x','[]')"> did not work.

He has checked in the fix - if you are tracking CVS you need to 
update lib/python/ZODB/TimeStamp.c and rebuild it. For those not
using CVS, I've attached a copy of the updated file to this email 
(but you'll still have to rebuild the extension for the change to 
take effect).

It is definitively not a good idea to rely on browser detection
for you pages. Especially if you dont already know how to do it.
Try to make your HTML-code not so special to let it work for all
browsers (you cant know how to handle the specific of all the
browsers available).
But, if you really cant live without it (please overthing it more
than twice!)
REQUEST['HTTP_USER_AGENT'] is your friend, together with various
string-operations.
Please note: you cant be sure if this field is set and tells you the
truth about the partcular user-agent.

Subject: [Zope] Syntax for getting property sheet
Message-ID: <m31z5mmy4y.fsf@wacko.pdx.net>

If I have a ZClass with a property sheet called 'Info', how can I get
access to the sheet when I DON'T have an instance of that ZClass to
work with.

Specifically, I want an ADD form for my ZClass that has an ID field
and a dynamically generated section containing all the properties from
'Info' all on ONE from.  I can't seem to figure out how to dynamically
generate the property section without an instance to work with.

Actually the guys at Spam inc. IT do model Spam cans (how about the lot 
numbers in case of botulism or something?) I believe the reference to 
Spam
was just an example though ;-)

More likely I would write a Class called "Table" that knows about 
accessing all 
relational database tables not just "Products" (see Data Adapters in 
Zope)

Would you have a different table for this?  This is a debatable topic -
if you don't have different attributes for your subclass then, it is 
argued,
you don't really need that subclass. Special methods for this can be 
done
as you propose or just tested for in one class.  The reason this is 
important
here (in this discussion) has to do with oo-relational mismatch or 
impedance.
When you are bringing back your objects from the database you are going 
to have
to know which object to "instantiate" (this term is used losely here). 
This means 
special handling for your queries. Or you can pay the pain by having 
two tables which
makes your queries for all objects harder. As you can see it isn't 
necessarily simple.

There are several ways actually --

This would translate to a "Stock" object with three attributes
as you have stated below -

Yes this is still olde kinderhook.

For me this method would be an instance method, each instance would 
have it called upon itself.

Actually you are correct. There will be an input program. You won't see 
much
difference between OO and your conventional database way (if you will 
allow me
to assign that term here). The reason is we haven't actually done 
anything
too significant yet.

Using my assumptions and examples from above I would have the Stock 
class
ask my table class to build a SQL query to do this

As above have the Stock Class have the table class find all "rows" which
meet this criteria then for each instance send updatePriceBy(2)
where the 2 is an argument and since it is positive the instance of 
stock
will add 2% to its own price

Here comes more spin though I'm afraid (sorry :-P)

Up til now I've left out alot of the mechanics.
The Table Object knows how to form SQL queries which gets you subsets
of your objects (not just rows of data) It in effect provides the code:

   product_1 = Stock(product_code="ABC",Description="Spluggifier", 
Price-"20.00")

only instead of product_1 it would be 'next_row' or 'this_row' 
(depending
on how you like to think of database cursors). Also somewhere there is 
a mapping between
the Table and the Class it represents. This allows the Table to become 
a Class,
the row to become an instance, and the columns to be attributes. These 
mappings
would be plugged into the above code also (i.e. product_code becomes 
attributes[1])

This mapping solution is a common pattern - IDL to Corba, DTD to XML in 
generic terms.
Here we start to see OO work. I defined my class and map it to 
different things
such as Corba or XML - now I can ship the object flattened as a string 
(or some other
form) and a reciever can inflate it back. This would be the user input 
form. This flattening has a special name in ZODB (as far as I can tell) 
it's "pickling"

Hope this doesn't add more head spin. There is much more to this story, 
we haven't
even talked about, such as foreign keys and how to map them to Objects. 
 

As far as modeling the data, I don't model a database, just the data, 
but it also
depends on if you are supporting a previously existing database or 
starting new.  I have done both and it is a black art. You have to 
support management, other departments etc without tipping the boat 
over, so you generally follow the flow. But for the most part you want 
to analyze the problem domain from an object point of view from the 
start. This gives you important insights to other parts of the problem 
such business processes and object interactions you didn't know about. 
OO is not just an elaborate ERD (Entity Relationship Diagram) But it is 
the most common place to start. This is just one way to do it, not 
necessarily the "Right" way, (if there is such a thing)

Hope this Helps

Other people answered your conversion question, I just wanted to point
out that the ':int' notation is meant for use in qualifying HTTP POSTED
data, like that coming from a form.  For example:

<form>
  <input name="bob:int">
</form>

This will cause ZPublisher to try and turn the value of this element
into an integer.  This is the only place the ':int' notation makes any
sense.  In your example, you have confused this notation with that of
the let tag.

Subject: [Zope] Property Sheet Question
Message-ID: <4.2.2.20000307143411.00b56800@saladin.aisys.com>

I'm defining a property sheet for a new ZClass object.  I want to define a 
property which is collection of items (in my current case it's strings, but 
conceptually it could be something else).  When a new instance is created 
(or edited), I want the user to be able to specify 0 or more items.  Is 
there a property type which supports this?  What, for example, are "lists" 
and "tokens" and how do you make use of them?  In the particular case that 
I'm working on, I want a user to be able to enter one or more e-mail 
addresses and one or more urls.  At some point I will want to iterate over 
the e-mail addresses, or iterate over the urls when I construct a view for 
this object.

Any tips or insights on this subject would be appreciated.

Thanks.

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Message-ID: <38C55EE7.36417628@digicool.com>

There is no standard rythem for manipulating the class without an
instance.  At least not that I know of.  It can be done, however,
because it can be done from the managment interface.  Anything that you
can do with clicks in a browser you can do with DTML, it's just in this
case your problem is necessarily complex because we never, ever,
considered your use case when we engineered ZClasses.  This is one of
the reasons why software can be dificult to use, because the engineers
did not KNOW in advance how you wanted to use it.

But you want to do this so I suggest you look at how the managment
interface traverses through the Control Panel and Products to manipulate
ZClasses. Using URL introspection, you should be able to deduce how to
do this.  I would help you but I honestly don't know how it would be
done myself.

I use IE5 on Win98 and NS4.7 on an old LinuxPPC box. No problems here with
Netscape running away though, I leave it running days at a time.

Netscape on NT/98 frequently runs into authentication problems with our Zope
install (using mod_proxy and ZServer) and sits there flickering the status
bar forever, whereas IE5 doesn't do that, it pops up the password dialog
when confused. IE does occasionally crash in the management screens (never
any other time), and I can't figure out why.

Subject: [Zope] manage_exportObject
Message-ID: <38C56A34.F9D9453B@globalcrossing.com>

Now I am desperate, this is the fourth posting and still only one reply.
Any thoughts no
matter how far fetched would be overwhelmingly appreciated.

Does anyone know how to export an object (Folder or such) from outside
of the Folder that contains the item to be exported without hard coding
the path. In other words I would like to be able to have a user
interface which would allow a person, with an export role, to be able to
enter a
list of fully qualified Items to be exported.

Consider:

FolderA
        FolderB
                ItemToExport

I can export ItemToExport from FolderA by calling:

<dtml-with "FolderA.FolderB">
        <dtml-call "manage_exportObject(id='ItemToExport')">
</dtml-with>




but I don't want the FolderA.FolderB to be hard coded. I would like it
to be a var that I pass into the method. Something like:

<dtml-with FullPath>

what should the syntax be. 

Thanks,

OK, but see you're trying to make Linux something it is not.  Linux is
not about marketing.  It is not about world domination.  We
specifically do not care about this :-)  Now, digicool is a company,
and they probably DO care about this.  Making Zope Free Software is a
great way for them -- and us -- to benefit.  So your comments should
be addressed at them if you want them to make the sale.  Not me, a
Linux hacker.

But see again, Free Software is not about marketing.  The name is
irrelevant to us.  Free Software is about what's *right* and what
*works*.  We leave the marketing to those that want to do it (such as
digital creations, or whomever else).  So again, write to digital
creations' marketing dept. :-)

have you figured out a way to move through the ZODB for a certain type of
object?  and then manipulate it in the way you need?  I'm having this same
concern from a project right now -- they are scared to put content in ZOPE
because if we move to another content manager- we may not be able to get the
data out (please point me to info). 

your secondary question is just as valid:  versioning lingo in zope is not
versioning as in source versioning but a 'temporary lock' on files.  things
look differently in/outside of versions.  thats versioning now.  how about
retaining 'versions' of a website (I think vignette does this) - so I can
call (if I had diskspace and *WANTED* to) my website and say, "what did the
frontpage look like last month?, last week?, two days ago?" <- anyone worked
with this, because this is what is typically referred to as 'versioning' (I
believe).

Thirded. I discussed starting somekind of Zope-XML SIG with Amos Latteier
and generally he's favorable to this, but how do we start? We need a mailing

Thanks.

What had me confused is that

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
<dtml-var Currentdate>

and

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">
<dtml-var Currentdate>

both display the same date string whereas I guess the latter should
display an error.  It only reports an error when I try to do something
else with the variable.

Hm, skilled developers do hack on Python! There's the Python people at
CRNI, there's Christian Tismer in Germany doing Stackless Python (which
offers interesting arcane features and a mild performance improvements),
there's the whole JPython group, there's John Skaller with his Vyper
project (a Python interpreter/compiler in Ocaml, one of the reasons
is more speed). Then there's the Python Types-SIG, which I urge you to
look at if you haven't already.

It is _less_ of a problem, but most Pythoneers are indeed interested in
speeding of the language. I haven't heard of zealots who want to hold
back speedups, as long as it doesn't do away with the power.

It'll be pretty difficult to make a beast like Zope exploit type-hints, though,
I think. By the way, the Types-SIG is working on type extensions to Python,
partially for performance (OPT), partially for better error checking (ERR)
and partially for better documentation (DOC). See:

http://www.python.org/sigs/types-sig/

And also see the new compiler SIG:

Type inference is not a simple thing to add to the language, though..

That's of course true. I heard Christian Tismer talk about making a 
register machine interpreter for Python, which could potentially speed
things up quite a bit. I shall ask him about this idea again sometime. :)

All true. Anyway, the only thing you're wrong about is that Pythoneers aren't
interested in improving performance. They are, but I grant you they're not
performance nuts like users of C or C++. :)

Ask Linus Torvalds. :) Anyway, Linux is what people do with it. Not what
people say about it.

I care about making Zope more popular, as there will be more Zope users,
more Zope hackers, and better free Zope support. More cool Zope goodies.
More Zope related jobs. I care about Zope marketing.

Even if you only care about Free software, you care about marketing it,
as you care about what's 'right', and therefore you want people to use
the right stuff; Free software. Right? :)

Alexander Staubo obviously was interested in Zope marketing. Why tell him
'we' don't do that, while some of us are definitely interested?
Free software is about people doing what they want. Let us do want they
want and don't speak for me. :) Thanks.

This is just a guess (I'm a Zope newbie too) but I believe

<dtml-return "['John\'s', 'Mary\'s']">

Will work.

In the second case, I guess <dtml-var CurrentDate> is recognizing that
CurrentDate is a reference to a function and calling it.

I understand, now, how that had you confused. Anyway, glad it's working!

These are what you want. In the case of tokens, it will separate each word
into a list element. A "lines" property separates each line into a list
element.

Tokens: 'foo bar baz' = ['foo', 'bar', 'baz']
Lines:
foo bar
bar
baz

Becomes: ['foo bar', 'bar', 'baz']

This should work fine using standard <dtml-in>s, since tokens and lines are
sequences.

The kernel internals of Linux use a 32 bit off_t, hence discussion of
large file support in the next kernel release.

I'm not seeing an x86 problem at all:

lukasiewicz$ uname -sp
NetBSD i386
lukasiewicz$ ls -l huge
-rw-r--r--  1 tsarna  users  17592186044415 Mar  7 12:41 huge

Granted, that's a sparse file (I can't afford that much disk space :^),
but it demonstrates that file offsets are not a problem.  As mentioned,
NetBSD's off_t has been a 64 bit type for about 6 years now, even on
i386 (and evey other platform).  In fact, off_t was made 64 bit in 1994,
and NetBSD/alpha didn't exist until 1995, so it was done before there
were any native 64 bit platforms supported.  :-)

However, it turns out that for Zope use, at least with FileStorage,
there is a problem, which turns out to be even an x86 issue but a silly
ANSI C spec issue.  Unfortunaly Python large file support is broken on
(32-bit CPU) NetBSD as a result -- I had to make that sparse file with a
little C program.  Now, you could have a more than 4G BerkeleyStorage
Zope system, since the file handling isn't done at the Python level in
that case, but FileStorage won't work until I can work around the Python
problem (or until NetBSD 1.5, which will fix it in a different way). 

But at least it's the kind of thing that could be hacked around in an
application by one guy in a day, rather than taking drastic kernel
and libc changes :-)

Packing does not modify your existing database file until it completely
succeeds.  During the pack, packed data is written to a temporary file
and your main file is just read from.

FYI, you are searching for the union of two search terms, 'ZODB' and
'troubleshooting' which is why you got more for the second query than
for the first.  To explicitly get an intersection, say 'ZODB AND
troubleshooting'.

That bring you back a much smaller number (0).

One place to start might be to join the Python XML SIG. It has a high
S/N and most of the discussion is probably relevant to the Zope XML
effort.

It would provide the benefit of knowing what's currently available from
AMK, Four Thought, etc., which might be reusable for Zope.

Four Thought's 4DOM, 4XSLT, 4XPath are getting pretty mature, with 4ODS
and 4XLink in the wings.

Additionally, if you haven't the bandwidth (I certainly don't) to
follow the xml-dev newsgroup, the XML SIG gives you a filtered view of
all the mighty standards power struggles going on as we speak in the XML
world, so you can have some perspective on the right time to jump on the
Schema train and so forth.

Thanks.
We will eventually be looking into optimisations for the list command,
to
reduce the depth of braches traversed. If any UW IMAP users can confirm
which flags represent what in that context, that would be helpful. Then
we
could avoid listing them.

Yes, I did get the following response from Drew:

--- snip ---

The easiest way to make changes to all of your SQL methods would be to
export your entire Data.fs into XML format -- then use your magic       
text editing software tools.

With respect to version control and configuration management, I have
used the same XML export format and checked this into CVS. Of course,         
I feel that XML is human readable... YMMV.

--- snip ---

I agree with this basically, and I can see this as a partial
solution.  Basically, if you were using this in production, you would
want to schedule a script to automatically pull out the XML export
from your site say, once a day, and check it into CVS.  Depending on
your needs and your ambition, you could probably go so far as to go
into particular folders and pull out peices of the site individually
and check those in seperately, that way you could look at "Show me all
objects that have changed since April 10th" or whatever via CVS.  This
would also allow you to rollback to a previous version (ala Software
Configuration Management type stuff) by checking out all peices to a
system from CVS and then importing them back into Zope.  Kinda a
hassle compared to how CVS automates other development environments,
but then, other development environments aren't quite web RADs
either.  At least you CAN export and import the data as XML.  A
similar situation arises with tools like Delphi etc where your forms
are binary files and you can't make global changes to them except via
point and drool^H^H^H^H^Hclick.

Note: I refer to scripting exporting.  At this time, there's no tool I
know of to do this.  You would need to do this yourself.  SO... if
there's anyone out there who is a wiz with the ZODB that could MAKE a
tool to pull this stuff out.  I'd appreciate it.  If it was me, I'd
just script something to pull it through the web interface, but a
non-web oriented, just run on the ZODB tool would be better.

Message-ID: <200003080133.UAA14797@saltmine.radix.net>

Ok, I've gotten pretty far with Zope this time.  But (of course), I've
got a bunch of questions.  Starting with...

1)  What is the algorithm for determining which method to call?  The
    DTML documentation says

  "attributes, including inherited and
   acquired attributes, of the client passed 
   in the call to the document template are searched"

   But in what order?   There can be an index_html in the class, in a parent
   class, or somewhere up the acquisition tree.  Which takes precedence?
   Does the product that a ZClass have anything to do with the search?
   What about Z-Super-Classes?  Inquiring minds want to know.

1a) Why can't I have a method in a ZClass, but then override it in
   the instance?  I.E. (Gaak, it has been a while since I've had to
   even think about C++) virtual methods?  (Or have I got that wrong).

2) It seems that the examples require the user to generate forms by
   hand, which seems unnecessary.  For example, (after a protracted
   struggle with the underlying python code) I wrote a method that would
   create an html table for any query, ripping the column names and data
   out of the result object.

   2.1) Shouldn't this be a standard part of Zope?
   2.2) If so, do you want this code?
   2.2) Likewise for property edit forms.  I did find some DTML that
        would do this, but shouldn't this be standard.

3) Anyone want to help me whip snmpy into shape and create soem
   nice Zope classes for accessing SNMP variables and tables in routers
   and such?  

Enough for now...

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time.  I get the following log

I would have to research this to give a precise answer. Basically, it all
depends on the current contents of the namespace stack. Generally, this
will search REQUEST first. Next, we look to the object containing the
method being rendered. Then, the object containing that object, etc.
Whenever a ZClass is queried for an attribute and doesn't have it, it
looks to its parent(s).

I made this mistake when first working with ZClasses, too. If you think
about it a little, you'll realize that, virtual or not, you cannot
customize an OBJECT in C++, only a CLASS. i.e.:

---
class A
{
public:
  int x;

public:
  A() { x = 0; }
};

class B : public A
{
public:
  int y;

public:
  B() { y = 0; }
};

A* objectA = new A();
B* objectB = new B();

objectA->x = 1; // Valid
objectB->y = 2; // Valid
objectA->y = 2; // Invalid, because class A has no such attribute.
objectB->z = 3; // Invalid, because class B has no such attribute.
---

If you want to customize an object (instance), you have to extend its
class, first.

In Python, this is not (really) true. Any old object is a dictionary, so
yuo can add attributes to it on the fly. Thus, the question, how can we do
this with ZClasses?

I wrote a base class that overloads ObjectManager's _checkId method to
allow instances of a ZClass to be customized. It looks like this:

---
from OFS.ObjectManager import bad_id

class Overridable:
    def _checkId(self, id, allow_dup = 0):
        if not id:
            raise 'Bad Request', 'No id was specified'

        if bad_id(id) != -1:
            raise 'Bad Request', (
                'The id %s contains characters illegal in URLs' % id)

        if id[0] == '_':
            raise 'Bad Request', (
                'The id %s is invalid - it begins with an underscore' %
id)

        if not allow_dup:
            if hasattr(self, 'aq_base'):
                self = self.aq_base
            if self.__dict__.has_key(id):
                raise 'Bad Request', (
                    'The id %s is invalid - it is already in use' % id)
---

This is not foolproof (it allows you to override TOO much, i.e. you can
create a method with the same name as a property), but it shows the idea.
I just subclass my ZClasses from this class, and I can customize each
instance individually.

Thanks a lot Ty for the detailed reply. Mostly for clarifying a few of
the stuff you were talking about at IPC. Seems to me that at least some of
the major components of Zope should be designed in this manner, but on the
other hand it is only after one codes a few specific situations that the
general pattern emerges.

Subject: [Zope] index_html for root
Message-ID: <001201bf88c0$8ad24e40$770da8c0@bbs>

The attached file is intended to replace the current architecture of header
body footer of current zope default index_html.

Together there will be some attributes which can be used to modify its
behaviors :

wap - when defined, set the content-type in RESPONSE accordingly according
to Ducan's WAP howto. and sent out the <wml></wml> tag.

xml - when defined, set the content-type to xml/plaintext and the xml header

frame - when defined, prevent sent out the body tag

Only one of the above can be set. I still got problem with acquisition: if
one of these is set in a higher lever, then all lowerlevel see it. Are there
any easy way to set them off?

doctype - when defined, should contain the correct doctype string: currently
the following doctype is available:

    html4.0
    htmlstrict4.0
    htmltransistional4.0
    htmlstrict4.01
    htmltransitional4.01
    htmlframe4.0
    htmlframe4.01
    xml1.0
    xhtml1.0

The following is defined inside the index_html:

dtml-head - the content of the <head></head> section
dtml-headers - the content of contructs before the main body: This should
not left any tag open.
dtml-footers - the closing contents of the main body. There should not
assume any opening tags.

index_htm - the main content. a frameset statement if frame is defined. If
the main content contains a table, then the main table is defined here, the
parts in the table can then be dtml-var. A index1 index2   .... or indexr1c1
index r1c2 .... naming convention is suggested.

I strongly suggest convert the current zope sites to adapt to this style
through much works shall be needed.

Further work would be in the dtm-head: Recently I will suggest to adapt the
W3C core styles : http://www.w3.org/StyleSheets/Core/Overview

All suggestion and comments are welcome.

Message-ID: <NDBBLBELNHAPHBBCOIFDGEHLCBAA.ewalstad@energywright.com>

Hi David and the rest of the group,

Can you believe I am still battling this MySQLDA installation!?  ARGH!

I hope you can help me out here:

According to the HOWTO by alanpog, I've
1. Downloaded MySQLDA 1.1.3
2. Expanded it into my top level Zope Directory (/usr/local/Zope) Note that
I did not do any installation here, just expanded it into this directory.
3. Downloaded MySQLdb v0.1.2
4. Expanded MySQLdb into /usr/local/Zope/lib/python/Products
4a. Modified the Setup.in file so that the one uncommented line is:
    _mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt
    As you mentioned, these point to where my MySQL libraries are.
4b. According to the README file, ran 'python build.py'
This is where I am stuck.  The build.py script crunches along then bombs
with the following error:

Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I checked and this file is in my /usr/local/lib/mysql directory.  It is a
link to libmysqlclient.so.6.0.0.  Both files are there; owner=root,
group=root.

I'm hoping this is a simple fix ;^)

Any idea's would be greatly appreciated!

Eric.

>Is there a HOW-TO or other documentation that shows how to set up a login

>advance for any help/pointers provided.

I don't know if there is a how-to but the way I do this is very
simple. I have a simple form with only a submit button with name login
(it appears on a sidebar of the web site).  When it is clicked it
posts to the current URL.

<dtml-if isRegistered>
You are 
<dtml-in "AUTHENTICATED_USER.getRoles()">
<dtml-var sequence-item> 
</dtml-in>
<b><dtml-var "AUTHENTICATED_USER.getUserName()"></b>
<dtml-else>
<FORM ACTION="<dtml-var baseURL>" METHOD="POST">
<INPUT NAME="logon" TYPE="SUBMIT" VALUE="Logon">
</form>
</dtml-if>

In the start of every page I call a method to check for 'login' in the
REQUEST variable. If it exists I calls or references an empty method
which anonymous users have no rights to but which authenticated users
do have access to (with ID login in this example.

<dtml-if "REQUEST.has_key('logon')"><dtml-var logon></dtml-if>
<dtml-call "REQUEST.set('isRegistered',AUTHENTICATED_USER.has_role(['Staff','Student','Manager']))">

Zope will therefore invoke the authentication mechanism which means
the browser will ask for a login a password as usual. From there on
the user will have been authenticated and you can check their name and
what role(s) they have in the current context. 

As you can see once with the code given here the user has logged in
instead of a login button they will see a message giving their
username and global role(s).

Hope this helps.

I am making a new head zope index_html file, I think it is now about time to
make use of the HTTP_ACCEPT_LANGUAGE which is sent by the browser to
indicate the perferred language.

The variable is a string like:

lang1, lang2;q=p1,lang3;q=p2....

while lang1, lang2, lang3 is the perferenced languages.

I have think of the following ways to make such brenches in zope:

1. by setting the lang variable in the REQUEST
2. by transfer to the brench of lang/
3. brench calls of index_lang

What will be the perferred way to make such a brench? I want to hear from
all.

In building the brench code : I have come up with the code:

<dtml-in "_.string.split(HTTP_ACCEPT_LANGUAGE, ',')">
   .....do thing according to sequence-item
</dtml-in>

but on the second argument, the sequence-item may contain ;q=0.5 which need
to be trancated. How can I trancated that in dtml?

It's quite nice being able to edit the site using Lynx,
but you cannot create new objects as the 'Add' option
box uses Javascript. Because it's listed as DISABLED,
Lynx won't let you pick a type before clicking on Add.

move to the new style <dtml- from <--# tags.

I'm also waiting for someone to write the "dtml-method beautifier".  :)

I played around with nedit's syntax-hiliting so it recognizes dtml as
opposed to regular html.  Not perfect, but better than nothing.  Plus I
improved the python mode a bit.  If any one wants it email me.

Nope.  There may be some standard python library module that I don't
know about, however.  Otherwise, you will have to write your own.

The first two follow standard python rules, first instance attributes,
then shared instance (class) attributes, then any base class
attributes.  THEN acquisition.

No.

Same rules.  First the instance of the ZClass attributes, then shared
instance (ZClass) attributes, then any base (Z)Class attributes.  THEN
Acquisition.

I think your confused but I'm not sure.  If your ZClass is a container
(subclasses ObjectManager) then instances of that class can contain
sub-objects (attributes) with names that are managable by the Zope
managment interface.  The managment interface will NOT however let you
create a sub-object in that container that conflicts with the name of an
existing attribute *including shared instance attributes like methods of
YOUR ZClass*.  Methods of a ZClass may look like sub-objects in a
container instance, but that are not, they are shared attributes of a
class, and all instances of that class will share those attributes. 
Now, this is a limitation/feature of the managment interface, it is not
a limitation of python.  If you want to assign an attribute to an
instance in python that has the same name as a shared instance
attribute, then that instance attribute will override the shared
instance attribute.

Ok.  You're talking about SQL Methods?

If you're talking about SQL Methods or other objects that implement the
Zope Search Inteface then it is allready a standard part of Zope.

You should look at what is there first and tell us how to improve it.

The managment interface obviously builds the property view dynamicly, so
something like this is in Zope.  Whether or not it is useful to others
is unknown to me.

Right, this is certainly a good place to go to as well. But Zope has its
own rather different requirements, and I think we need a seperate place
to discuss adapting all these technologies so they'll work with Zope -- 
the people in the Python XML-SIG might not care about Zope.

Also, the Zope XML list should also be the place where people ask *questions*
on using Zope with XML; this way we learn more about what people want and
what problems they may be having. And that way we can improve Zope's 
XML support. The Python XML-SIG wouldn't be the right place for that.

Okay, I was considering joining that SIG anyway, but I don't think it's
enough for developing Zope's XML support.

I would say that I specifically do care about this. As a freelance 
developer I want there to be good recognition of Zope in the market place. 
It is all about recognition. I was extolling the virtues of Zope to the IT 
Director at a client and he said 'So why haven't I heard of Zope ?'. My 
answer, that it was all very new and on the verge of success probably did 
not convince him. (Of course it is all very new and it is on the verge of 
success ).

If I say Linux, Perl or C then management are usually quite happy. These 
are recognised names - but nobody owns them. SO it is possible for free 
software to be successful in the sense that they are as well recognised as 
commercial products (which have huge budgets behind them).

Some management (perhaps most) will prefer to buy a "fully supported" 
product from a major player. We don't need to take on that kind of 
marketing head on. Rather we can present Zope and Python as tools to do a 
job, not strategic decisions to be made by management. However it is 
reasonable for management to ask "Will Zope be around in three years" - 
"can we de-Zope if we have to" - "Who owns Zope" "Who uses Zope". Managers 
are not likely to take a "risk" on a product. At the moment they usually 
feel happy that Linux, C and Perl are going to be around in three years time.

If Zope is to succeed it will be because of its capabilities as a product - 
because it installs out of the box in six minutes, while the Microsoft 
equivalent takes 5 hours. Because 60 minutes after downloading it you can 
be running a web page which interrogates your legacy databases (which is 
what happened to me).

We know about the documentation issue, which is hopefully being sorted.

I feel there is also an issue with the product itself. Zope seems to work 
on two levels - you have a very high-level part - I'm thinking of the 
security model, the SQL methods and the Z Search interface, the drop-in 
products like SquishDot etc. These set Zope apart from other technologies 
which people might use (PHP/ASP etc).

You also have a low-level  part (External methods etc). Because Zope has 
the high level part it encourages the thought that there is not much 
'programming' needed to develop a Zope site. But sooner or later you are 
going to hit a wall - for example questions you see asked on this list such 
as "how do I assign a value to a variable". Well the answer is ...

<dtml-call expr="REQUEST.set('abc_search', strip_abc(abc_text))">

... a string of gobbledygook. (So what does the dtml-let tag do is the 
obvious question that springs to mind.)

It is great that Zope has the low level stuff but I feel that work needs to 
be done

1) To analyse actual usage of Zope to see what features are being used and 
which areas of usage cause concern/difficulty
2) To Implement high level dtml tags to implement them.

I've stuck my neck out here - feel free to chop it off.

How do I call the stored procedures written in Oracle from
"Add a SQL Method" interface, especially when there are OUT parameters
returned from stored procedures? I have read the DCOracle mini how-to
but there seems to be a missing step ahead.

Assume the scenario:

Oracle Procedure: myProc(para1 IN  VARCHAR2,

What should I put in the "Arguments" box and "Query template" box? 
And how do I retrieve the returned arguments in the following dtml
document/methods? Thanks a lot!

Yes, I care too. And for the exact same reasons. The more popular Zope becomes,

Yes. Alexander has brought up a very (IMO) relevant issue. It is in the
interest of the entire community to make Zope well known and I feel marketing
should not be left just for DC to take care of.

I see a number of articles/sites about 'app servers' which don't mention Zope
but mention others (including some mickey mouse servers I've never heard of).
Eg: http://serverwatch.internet.com/appservers.html
Why? Maybe Zope isn't talked about at all outside some circles?

Altavista shows about 1058 pages linking to zope.org (compare php.net:12,000 ;
apache.org:60,000). Why?

If nobody does anything, this will take time to change. If we want this to
change faster, all of us have to actively market Zope. This involves talking
about in appropriate newsgrousps, putting up zope webpages,
making Zope easier to learn and use, adding flashy features etc.
All this can make a whole lot of difference.

Still it would be sensible to do it by splitting the database file (say at
1M boundaries rather than supporting some obscure non-standard system calls 
that only few platforms support. Probably also one-day hack by someone 
who knows where to start digging.

At least this is how it was solved for PostgreSQL .

Subject: [Zope] getting object reference from an id string?
Message-ID: <001001bf88f9$4b84eca0$a1ac8ec6@hikari.anu.edu.au>

Say one has an object reference and knows the
string id of a child node.  From this info, we
want an object reference to the named child.

I'd like someone to prove me wrong that there
is not a one-liner to accomplish this seemingly
trivial task.  I've had to resort to (off the
top of my head) code like:

<dtml-in "objectValues(['child meta-type'])">
   <dtml-with sequence-item>
      <dtml-if "id == desired_id">
          <dtml-call "REQUEST.set('desired_ref',_['sequence-item'])">
      </dtml-if>
   </dtml-with>
</dtml-in>

I'm really looking for a solution that doesn't
require looping.  Since Zope enforces unique id's
at a given level, the name should be sufficient
to resolve the child object.

Darran.

just use 'reverse'

   If you remember, it wasn't done in a day. There was a long period of
bugs, esp. bugs in VACUUM.
   I wouldn't buy your idea of easy splitting Data.fs. Exactly like with
the VACUUM, packing Data.fs would be complex task if the data will be

The claim of "a days hacking" was meant as an ironic counterclaim to it being 
a day's job on *BSD

I would suggest it by implementing a file-like HugeSplitFile class and 
using that to hide all the splitting from all other layers. 

If we could implement it in python then it would be perhaps a 1-hour job, 
leaving the rest of the day for fixing up the parts of zope interfacing 
with it ;)

It would probably consist mostly of adding long() to some initialisation 
functions.

   This is a record object. You should use:

On the other hand, if you tell the user up front that HTML tags are not
allowed, you can simply html_quote the text.  That will prevent any tags
from rendering, and prevent normal uses of '<>&' characters from breaking
anything.

Subject: [Zope] Performance and Concurrency
Message-ID: <200003081355.IAA06034@saltmine.radix.net>

I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute).

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

to take the html and turn it into plaintext.
Pop it into an external method something like the following, and it should
do the trick:

---html2msg.py

from popen2 import popen2
def html2msg(htmlstring):
  try:

    (r, w) = popen2('/usr/local/bin/w3m -dump -S -cols 70 -T "text/html"')
 
    w.write(htmlstring)
    w.close()
  
    s = r.read()
    r.close()

    return s
    
  except:
  
    return 'Error converting article to plaintext.'

It's an ugly hack, and you lose things like <br> and <p>, so you may want to
replace \n with <br> afterwards. It does, however, do a brilliant job
layout-wise: tables and lists remain fairly well formatted, for example.

Sorry, I wasn't clear.  What I was looking for was a method to get,
for example, an html table out of what an ZSQL method returns.  I
had to look at the code under lib/python/Shared/DC/ZRDB to figure
out that calling a ZSQL Method returns a Results object, and then
look at the results object to see that it has methods like names(),
data_dictionary() and tuples().  Then I could write a loop like...

    <dtml-with "Your-query-method(parameter=value, parameter=value)">
    <table border=1>
      <tr>
        <dtml-in "names()">
          <th><dtml-var sequence-item capitalize spacify></th>
        </dtml-in>
      </tr>
      <dtml-in "tuples()">
      <tr>
        <dtml-in sequence-item>
    	<td><dtml-var sequence-item></td>
        </dtml-in>
      </tr>
      </dtml-in>
    </table>
    </dtml-with>

My point, I guess, is to suggest that this should be a built-in method
in a ZSQL query.   Unfortunately this would also hard-code the
appearance of the table unless it had lots of options.

I'm probably missing something.

I did find code that kind of did this in the manage_test method in the
ZRDB/DA.py file, but when called returns manage_tabs, and also access
some non-dtml-accessible functions like result._serachable_result_columns().

I'm sure I'm missing something, but this doesn't seem accessible from DTML.

Once again, there is code to render property table forms, but it is 
buried inside lib/python/OFS/properties.dtml.  Once again, it seems
as if a standard method to generate a form for editing properties
would simplify creating applications by eliminating the need to
type in, by hand, the required forms.

I've seen a couple of pieces of code, both in the mailing list and
on zope.org to do this.  

The overall goal is to make it easier for beginners to whip up an
application without having to know too much about html forms and
formatting.  Plus to make the system easier to maintain by not having
redundant information (i.e. in the property sheet or query, and also
in the DTML that renders it).

Thanks for your time...

I forgot to try that (I tried using alternative quote characters and that

In my ongoing efforts to gain a bit of recognition for the capacity of
Zope, Python,  and all things Open Source, it looks to me as if Marketing
Matters, regardless of my wishes. Even if, to me, the validity of Zope /
Python is "obvious", it is not so clear to others, and especially others
who make decisions about tool selection. 

At some point, if Zope / Python is to find a place in the larger world,
these folks must be convinced. There may be a more palatable word, call it
"education", "concsiousness raising", or some other more trendy phrase.
Still, you can get the gist from the words, "selling", "marketing", or even
"hype".

Check out some of the articles by the folks at Bynari Associates (any
search engine will get you there). You can see the need for marketing of
Linux and Open Source tools in their daily business. In fact, the articles
themselves are a form of marketing, gaining name recognition for Bynari
(see, it works!) in the Open Source community, while sharing the benefit of
their "real world" experiences of implementing "Linux" for paying clients. 

In short, the line between the coder and the customer relationship doesn't
look quite so distinct from here.

Later,
Jerry S.

Message-ID: <3.0.1.32.20000308102356.0068b264@bizux.net>

I am new to Zope but I am very appreciative of the How-To's and Guides that
have been produced by those that are more experienced than I in the use of
Zope. 

I am currently working on intranet for the company I work for, and am
having problems creating an instance of a ZClass, that I created, (DCTask,
which is actually the product, DCTaskClass is the ZClass)through the a
public interface (form that requires the entry of information that will be
added to the instance in the form of properties, such as the description of
the task and which department it is created for).

The form that is used to submit a creation action resides in a created
folder (http://diis/tasks/generator) and therefore does not reside in the
folder where the DCTaskClass_add method resides. I think that my main
problem, though I could be wrong, is that I haven't found a way to access
the _add method from the /task/generator folder through the use of the
<FORM ACTION="...">. I believe that once I have can access that file
through the form action and have the ability to send all of the relivant
information I will be able to create instances through the use of the
public interface (ie. the form)

Any help will most appreciated.

Best regards,

If you have a programmer and a web designer around it's possible to 
seperate the two tasks quite well, though, in my experience. Likewise a
situation with a programmer and a content manager, which is the situation
I'm in right now.

Still, both the web designer and the content manager want to know more
about Zope, and this does throw them off into the deep end (Python,
DTML, object oriented programming, etc).

I won't chop it off; you're right. Though I would say a simpler DTML
is only half of the story; the other half of the story is already there --
people _can_ use drop-in components. It's just that we need more and
better drop-in components (with possibly a nicer interface, ala Zope PTK
and/or Zope Mozilla).

Still, a simple variety of DTML would be nice. Currently you can
successfully use a subset of DTML, which almost has no arcaneness but
is still very powerful. PythonMethods will help even more there. Still,
DTML allows too much, so it's too easy to move into the arcane domain. Also
some of its powerful features have the side effect that some of the simple
features look too complex.

So perhaps we should create a seperate language, based on the subset,
with simplified syntax, which _doesn't_ allow fancy stuff. The fancy
stuff would be in DTML-methods or PythonMethods of some kind. Perhaps 
even the HTML would be in seperate methods. Perhaps some XML-ish Zope
glue language, like this:

<zopeglue>
<var object="header"/>

<assign name="age" object="get_age"/>
<var object="show_age_intro" arguments="age"/>

<var object="layout.table_header"/>
<in object="get_above_age" arguments="age">
<var object="myrecord" arguments="in_item"/>
</in>
<var object="layout.table_footer"/>

<assign name="age" object="getage">
<var object="footer"/>
</zopeglue>

And then some IDE that allows you to easily create all objects you
refer to here. Perhaps something wiki-like; any object name that you refer
to in the glue that can't be found will be presented in a list after you
edit the glue, and you can create objects for it then.

Ideas, ideas, now for some time. :)

Martijn

I would recommend taking a look at how the management interface does things.
(Just do a View Source in the Zope management frame that has the pull down
menu listing the different things you can add).

In KM|Net News, I made the incoming article form post to a DTML method
(AddArticle) that basically follows the steps in the "Adding ZClass
Instances Programmatically" how to.

http://www.zope.org/Members/tazzzzz/addZClasses

I haven't tested this, but posting your form to:

"manage_addProduct/YourProductName/YourZClass_add"

may do the trick, assuming your form is being called from the Folder where
you want the new instance created. Otherwise, you should do something like:

"/FolderForNewInstance/manage_addProduct/YourProductName/YourZClass_add"

The new scheduled DTMLMethod product, ZScheduler, can do that. Just schedule
the method for "now". Only works with DTMLMethod's but they can call any
other kind of method. The product is in alpha stages right now, so I
wouldn't use it for a production environment just yet, but I would
appreciate knowing whether it's useful for your application.

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time. 
The Z2.log file shows
123.123.123.123 [08/Mar/2000:16:49:40-0700]

The actual system time is  8:49 pacific time.
NT 4.0 show   (GMT-0800 UTC)  Pacific time (US and Canada);Tijuana
It and is set to automatically adjust for daylight saving time.  

I have a NT 4.0 windoze  workstation machine that is running Zope latest version 2.1.4. and of course python 1.5.2.
  
Is there a script file that needs adjusting to make the file log correctly?  I know that -700 is UTC is Mountain Standard Time.  Do Zope programmers like the warm southern climate better than the cold  climates?  In short can this "default" be changed.

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

Subject: [Zope] Setting title in an external method
Message-ID: <20000308121007.A561@cnri.reston.va.us>

Hi all --

A common idiom around here is to use an external method to process a
form and, if an error that the user can't fix occurs -- eg. you can't
view such-and-such an object because it doesn't exist, or you don't have
privileges -- use "return" to show them the contents of a DTML method
that explains the problem.

Here's a simple example:

    def my_xm (self, REQUEST=None, RESPONSE=None):
        # ... churn away, processing the form ...
        return self.my_dtml (self, REQUEST, RESPONSE)

Here's the source for the "my_dtml" DTML method:

    <dtml-var standard_html_header>
    title: <b><dtml-var title></b><br>
    document_title: <b><dtml-var document_title></b>
    <p>
    This is the <dtml-var document_id> Document 
    in the <dtml-var title_and_id> Folder.
    </p>
    <dtml-var standard_html_footer>

Both "my_xm" and "my_dtml" are in the root directory of an almost-fresh
Zope 2.1.4 installation.

The problem is that the "title" when I call "my_xm" (ie. the "Title:"
HTTP header and "<TITLE>" HTML tag) is just "Zope", which I presume is
the title *of the folder* containing the external method.  Yuck.  I want
the form result to have a title of its own, eg. "Error Viewing
Blah-blah".

What's the best way to do this?  Possibilities that occur to me:

  * redirect to the error-reporting DTML Method instead (but I like
    to keep the number of redirects to a minimum)
  * use a DTML Document instead of a Method (not sure if this will
    work, and sometimes I really do want it to be a method -- eg.
    it might be called from within a larger Document in some context)
  * set some magical attribute of 'self' or 'RESPONSE' in the external
    method; I tried "RESPONSE.setHeader ('Title', 'My Title')", but
    that didn't work

Any other ideas?  Thanks --

        Greg

This is the code that I have for adding the adding ID of the instance of
the class (it provides a random ID or at least generates on)

<dtml-call "REQUEST.set('id',_.random.random()*10000)">
<dtml-call "REQUEST.set('id',_.str(_.int(id)))">

I copied (and modifyed slightly) this from the How-To: AutoGenerate Random

Try htmllib.

The following bit of python will strip all formatting from some HTML. It 
replaces all anchors with footnote style references and images with 
their alt text. If you want something a bit fancier you could add 
methods to the MyParser class to pass through particular tags (see 
the commented out methods as an example). It shouldn't be too hard 
to wrap something like this up in an external method (as presented it 
is a complete runnable program that retrieves a URL and displays 
the text).

--------- File strip.py --------------
# Strip all HTML formatting.
import sys,formatter,StringIO,htmllib,string
from urllib import urlretrieve,urlcleanup

class MyParser(htmllib.HTMLParser):
    def __init__(self):
        self.bodytext = StringIO.StringIO()
        writer = formatter.DumbWriter(self.bodytext)
        htmllib.HTMLParser.__init__(self,
            formatter.AbstractFormatter(writer))

    def gettext(self):
        return self.bodytext.getvalue()

# Uncomment these to pass through bold tags.
#    def start_b(self, attrs):
#       self.formatter.add_flowing_data('<b>')
#
#    def end_b(self):
#        self.formatter.add_flowing_data('</b>')

def GetPage(url):
    try:
        fn, h = urlretrieve(url)
        text = open(fn, "r").read()
    finally:
        urlcleanup()
    return text

if __name__=='__main__':
    data = GetPage(sys.argv[1])
    p = MyParser()
    p.feed(data)
    p.close()
    text = string.replace(p.gettext(), '\xa0', ' ')
    print text
    anchors = p.anchorlist
    for i in range(len(anchors)):
        print "[%d]: %s" % (i+1, anchors[i])
--------- end of strip.py --------------

Subject: [Zope] Object Manager and Folder
Message-ID: <E12SkGf-00074X-00@home.delysid.org>

Hi.

I am quite new to Zope and currently try to create a BookClass ZClass Product.
I came across several issues where you probably can give me some useful tips:

1. What is the difference between inheriting rom Object Manager and/or Folder.

2. My product will include Cover Images of the books. (a small and a large one).
Whats the best way to implement this? I thought about creating emtpy images (smallcover and largecover),
but I dont know how to ask the Objects if they contain something.
Or should I just add the Images in my BookClass Instance programmatically?

3. Wasn't their any web-client product for Zope so that I could retrieve content from the web directory and import it in Objects (like a Image) without having
to upload it manually?

And the last one:
Is their any special reason why FTP access doesnt work in the /Control_Panel/Products folder?
All methods are empty their. I work with Emacs and ange-ftp is quite
a good method to access content of Zope Objects.

Besides, if I change the content of a Object through the web interface,
Zope seems to convert < > and " chars into &lt; &gt; &quot;
I understand why, but is this really necessary. It seems as if nearly all
textmode browsers (as lynx and emacs/w3) dont care about converting the entities back tto their corresponding characters.

Thanks in advance,
               Mario <mlang@delysid.org>

If you can figure out improvements on how to configure UW IMAP for
interoperation with WorldPilot that would be great. We're currently
lacking 
a UW IMAP server with a reasonable amount of data on it for looking into
the
issues.
I'm putting in a parameter to control the LIST call, I think that should 
reduce the load for the large part of the users, but we're open for any
further
adaptions.

Ryan

I am hoping to add some performance benchmarks, quotes, etc... In other

Message-ID: <OFA5CFA31F.A45A80B0-ON8525689C.006234C6@ssga.ssb.com>

I just installed Zope (on NT) and would like to have reasonable
backup/recovery options.  One way to do this is to just make a copy of the
data.fs file in the var directory, but I'm concerned that this file may not
be in a consistent state when it gets copied somewhere.  Should I worry
about this?

I'm thinking it would be better to eliminate this file in favor of an
Oracle or Sybase database (I have access to both).  Can I do this?  If it
is possible, would I want to do it?  If I should want to do it, how do I do
it?  I've spent a few hours searching the documentation, but this has only
convinced me that it may be possible -- I've been unable to find a
definitive answer.

Ok that seems to work because I am getting other errors and I think this
task is a little advance for a zope infant like myself. Now, this line is
causing me problems (this happened after I called entered the hidden field):

<dtml-call "REQUEST.set('id',_.str(_.int(id)))">

The error it gave me was:

Error Type: ValueError
Error Value: invalid literal for int(): generator

It seems to be refering to the "(.int(id)))" of the above code.

Dave & Chris,
Thanks for replying.
I'm running Caldera OpenLinux 2.3.  I chose it because I heard that it had
one of the smoothest installations.  I am only a few months into Linux; I'm
transitioning over from the Dark Side (Microsoft).  Heehee.

Here's my best guess at what's going wrong with the MySQLDA/db installation.
I think it is related to access rights or locations to the
libmysqlclient.so.6 file.  When I run build.py, I can see the script
accessing the MySQL library folder (in my case: /usr/local/lib/mysql)  This
is the path the MySQL 'make install' script displayed when it was done
installing MySQL.  I checked, and the library files are there.  Anyway, I
can see the build.py script working some of its magic within this folder, so
I feel confident that the paths in the Setup.in file are correct.  However,
it is crashing when it tries to "from _mysql inport *".  I am not (yet) a
Python programmer, so I don't understand the implications of this import.
I'll reprint the error message I received for anyone else that reads this:
Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I like your idea of making a link to the MySQL library file
(libmysqlclient.so.6).  I know this is a stupid question, but if I run:
ln  /usr/local/include/mysql libmysqlclient.so.6
what will the link be called, and where will it be located?  How will this
help the build.py script?

Thanks again for your input!


Chris,
This seems to be pretty common which makes me feel, well, not alone...

Thanks for the note and I'll keep you updated on my progress.

I reinstalled linux (probably didn't need to but I did)  I used an older

# ln  /usr/local/include/mysql libmysqlclient.so.6
and see if it can now find the libraries/files it needs.

Are you sure that the Setup.in path is correct?  I looked at both these
files build.py and MySQLdb.py they both refer to libraries and their
respective location.  Anyway good luck and if you get an answer, please let

I probably going to change over to mandrake linux for security reasons.

I've never used Caldera's distribution, but if it's anything like Red Hat,
the following should work:

1) Open /etc/ld.so.conf with your favorite text editor and append the
directory in which libmysqlclient is located.
2) Run 'ldconfig'

This will update the list of directories that the linker searches.

Let me know how it goes.

improved and there's certainly room for more. Perhaps there should be a 
coordinated 'wish list' on zope.org so that developers can pick up on 
needed products, or collaborate  on enhancements of existing products ?

Agreed <dml-var object> is a pretty good start for most people.

><var object="layout.table_footer"/>

><var object="footer"/>
></zopeglue>

Well that's a bit further than I was proposing. Perhaps I would settle for 
dtml which accessed the REQUEST object more simply. However your syntax 
looks good.

What "non-standard" syscalls? I'm talking about calls like lseek().

Yes, spawn a new thread.

WARNING this can cause havoc if not done properly.  For example, if you
want your seperate thread to be able to read and write data to the
database, you MUST open a seperate connection to the DB.  If your thread
goes away, you MUST close that connection.  There are a couple how-tos
on the site that explain database connections.

Yes, that makes sense. When it looks up "id" in the namespace, it first
comes across the id of your method. You're specifically wanting the "id"
from the REQUEST variable. So, the line should be:

<dtml-call "REQUEST.set('id',_.str(_.int(REQUEST['id'])))">

Nope. The Data.fs file is simply appended to when things change, and it is
quite safe to just copy the file over.

It *can* be done, but you would need to write your own ZODB Storage
mechanism for it. Right now, there are a few Storages available. FileStorage
is the most common (the one that works with Data.fs). There is also
CompressedStorage and BerkeleyStorage. No one has written a storage for an
RDBMS yet, but it should be possible.

Would you want to do it? Probably not. The FileSystem storage is pretty
solid. About the only thing you'll get from the RDBMS storage is that you
wouldn't have a file that keeps growing with every transaction and needs to
be packed from time to time.

Hi Chris (Carlson),
Thanks for the reply!

1.  I added the following line to my /etc/ld.so.conf file:
    /usr/local/lib/mysql
2.  I ran 'ldconfig'
3.  I re-ran build.py.  Here is the new error message. (notice that the last
line changed from before):
Traceback (innermost last):
   File "build.py", line 14, in ?
     import MySQLdb
   File "MySQLdb.py", line 19, in ?
     from _mysql inport *
 ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

Note that the file '_mysqlmodule.so' is in the
'/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' directory

4.  I tried adding '/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' to my
/etc/ld.so.conf file, re-running ldconfig, then re-running build.py, but I
got the same error.

It seems like we are getting a little closer!  Any more guidance would sure
be appreciated!

Thanks again,

Eric.

Subject: [Zope] Zope authentication problem
Message-ID: <v04220807b4ec46d1b515@[192.168.0.16]>

I apologize in advance for this note. I know this topic has come up 
several times in the archives, and I swear I've read every post, 
every how-to, and every other bit of documentation I can find. I 
can't get past the management screen authentication for Zope with 
Apache.

Here's my environment:

OS:		RedHat Linux 6.1

Zope: 		version 2.1.4, installed from Jeff Rush's RPMs (thanks, Jeff)

Zope PCGI:	version 2.1.4, also from Jeff Rush's RPMs (thanks again, Jeff)

Apache:		version 1.3.9, installed from the Red Hat RPMs (both base
		and devel RPMs are installed)

Python:		version 1.5.2, from the Red Hat RPMs


I'm configured as follows:

Zope install directory:		/var/zope

Zope.cgi:			copied to /home/httpd/cgi-bin/Zope
				(not a symlink, and renamed 'Zope')

access file:			/var/zope/access, contains:
				admin:cleartextpassword

httpd.conf contains:

RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/static/(.*)   /home/httpd/html/$1 [l]
RewriteRule ^/Zope(.*) /home/httpd/cgi-bin/Zope$1 
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

(that last line is all one long line, and I'm pretty sure I've sorted 
out the ls and the 1s properly)



Zope is launched with the following command:

cd $INSTANCE_HOME  (/var/zope)
/usr/bin/env python z2.py               \
         -z      /usr/share/zope         \
         -u      zope                    \
         -Z      /var/run/zwatchdog.pid  \
         -p      /home/httpd/cgi-bin/Zope \
         -w      ''                      \
         -f      8021                    \
         -m      ''                      \
         -l      /var/log/zope           \
         2>&1 >> /var/log/zope           \
         &

I can access all my other (non-Zope) CGI programs normally. I can 
access my static html with URLs of the form:

	http://server.ucop.edu/static/some_silly_url.html

So, I'm pretty sure that both CGI and the rewrite modules are 
installed, configured, and working properly. I can run Zope and see 
the QuickStart materials, so I'm pretty sure that the basic Zope 
installation is correct. But I can't get authenticated to Zope. 
There's nothing in the logs for httpd or Zope that looks interesting 
to me:

httpd - access_log:

207.212.67.31 - - [08/Mar/2000:10:14:18 -0800] "GET 
/cgi-bin/Zope/manage HTTP/1.0" 401 1388

Zope log (syslog messages file):

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- - 
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782

/var/log/zope is empty.


I've tried about a zillion other things, including installing the 
Zope binaries instead of the RPMs, and installing and building the 
Zope source. In every case I end up with the same result. Zope 
doesn't accept the authentication. One oddity I noticed is that if I 
access Zope through:

	http://server.ucop.edu/Zope

it immediately requests authentication. It doesn't even show me the 
opening screen or allow me to browse the QuickStart. If I dodge 
around the RewriteRule by going directly to:

	http://server.ucop.edu/cgi-bin/Zope

then it doesn't ask for authentication until I try to hit the 
management screen.

I should probably add that I tried using the built-in Zserver Python 
package and it worked fine. I haven't tried Zap. I would prefer to 
use Apache because I want to serve a mixture of legacy HTML and Zope 
content. I would prefer to use my own Apache instead of Zap because 
in general I'm not comfortable with using a package that I can't 
maintain at the current release level. Zap Apache trails plain Apache 
releases, at least by a little bit. I've tried a whole raft of 
variations on the rewrite rules in Apache. I'm stuck.

Anybody out there been through this already?

We need a couple more data points before we can blame Zope for this or

Try just REQUEST.set('title', 'Foo')

Folder inherits from all kinds of other things, including
ObjectManager.  Basicly, if you want your object to be a container then
subclass ObjectManager.  If you want to look and walk and quack exactly
like a Folder, use Folder.

They have a getSize() method that returns the length of the Image (Files
have this too).

Sure.

Yes, any automatable HTTP client will do.  You might want to look into
ZClient, or xmlrpclib, or httplib.

Yes, because we haven't implemented it.

Yes it is, I'd like to see this too.  I don't think it would be too
complex for someone to do, certainly FTP support is fairly trivial.  For
this you would need to mine the source.

I don't understand.  Editing a DTML Method through the web should not
munge it in this way.

Create an new kind of Storage module that stuffs database records into
table rows, instead of a file.  We've hypothisized on this, and it is
very possible (the 'fs' in Data.fs means 'FileStorage', which is the
kind of storage used by default on Zope.  Other storages include
DemoStorage, BerkeleyStorage etc.  There is no saying you couldn't have
a RelationalStorage).  Butdo you REALLY want this?  Consider:

1) Relational databases do not store previous revisions of record
information.  You will have no Undo capability.  I guess with some
extremely fancy SQL or if you engineered the Storage to do some kind of
mapping, you could emulate the storage of previous revisions.

2) One of the benefits of RDBMS is that they can be used by outside
applications.  The data Zope stores however will be record objects,
basicly python pickles, information which is useless to other apps.

However, it's really not a bad idea, except for the no Undo part.

Yer gonna kick yourself if this is it, but I believe that you must have
a RewriteCond before each rule that you want the conditon to apply to,
so in this case your authorization information is poked into the
environment for your static content, but not Zope.

Duplicate the second line after the third and see if it works.

Subject: [Zope] Referencing a Zope Instance through a Hyperlink
Message-ID: <3.0.1.32.20000308144541.0068c798@bizux.net>

I have a group of ZClass (DCTasks) stored in a folder
'/tasks/generator/taskstorage'

The index_html of '/tasks' is the interface to view the instances and
certains properties that are saved on those instances. One of the
properties is 'task_title' and is displayed as a hyperlink to view the rest
of the properties of the instance.

This is my problem, when I check the source of the page (/tasks/index_html)
and I take a look at the hyperlinks for viewing the properties of the
instance, it gives a URL like so:

http://diis/tasks/generator/taskstorage/<string>

<string> should actually be replaced with the 'id' of the instance. This is
so by the DTML code for index_html:

<a href="<dtml-var URL1>/generator/taskstorage/<dtml-var id>">
  <dtml-var task_title>            
</a>

I have no idea why a string is taking the place of <dtml-var id> in
referance to the instance.

Any ideas would be helpful.

Best regards, 

MJ Stahl

Well, basically what you are doing here is moving the point of
potential corruption from zope to the relational database.  This may
or may not give you any comfort.  For me, it makes me more nervous
since I don't have the source code to those particular databases, and
thus couldn't fix things if the worst does happen.

World domination has nothing to do with it. If Zope were the only tool
out there (or if it were enjoying the same kind of monopoly iron grip on
the market), that'd not be a Good Thing.

At the moment, Zope is still very much a "guerilla" product. It follows
that you might have to use guerilla tactics to lure it into your
company. Like Linux was just 1-2 years ago.

Arguably, free software (or Free Software) is about freedom, not
necessarily about what's right or what works.

RMS, arguably the grand old man, top banana, and icon of the Free
Software movement -- which is not the same as Open Source -- openly
admits he'd rather have bad, free software than good, non-free software.
The Open Source movement takes the pragmatic view that bad, free
software isn't an improvement at all, and that the software industry has
little use for RMS' moralisms. The Open Source guys just wants "software
that doesn't suck".

Perhaps Free Software people don't care about marketing. But then making
good impressions or having good hygiene has never been top priorities
for geeks. ;-)  For some people, outward perceptions do count. I flinch
every time somebody sets up Microsoft Exchange Server, or buys some
pricey piece of non-compliant Internet software, or seriously argue the
significance of ASP.

The people who make such decisions are often, sadly, uneducated about
what's good and about "software that doesn't suck". *Other* people
suffer because of such misfires.

Here's a different perspective you might not have taken into account in
your salutations to the spirit of Free Software. If Linux *hadn't* been
picked up by huge corporations and stock markets, if Linux *hadn't* been
rampantly commercialized, would we have seen the surge of wonderful
developments and innovations for the OS that we're seeing now? Methinks
not.

As much as I abhor commercialism and the new Linux hype, Linux' implicit
"world domination" plan is doing good things for the OS. Linux is not
the ultimate OS and hopefully won't be the last stop on the way to
utopia, but I rather look forward to the point where it's usable as a
desktop OS and I can forever throw out the software I know for a fact
sucks.

Marketing, in the case of Open Source/Free Software, is mostly a tool to
educate ignorant brass. *We*, as you point out, don't need the stuff.

Subject: [Zope] Puzzling DTML method results
Message-ID: <4.2.2.20000308154134.00b99280@saladin.aisys.com>

I'm encoutering a puzzling result with some DTMLMethods that I've 
written.  I have some code which is used to display a list of information 
derived from a catalog.  The information presented varies, based on which 
"category" of information the user desires.  The DTMLMethod which generates 
most of this information looks like this:

<dtml-in "InternetLinkCatalog(meta_type='Internet Link Info', 
categories=_['categoryName'])" sort=name>
    <dtml-with "InternetLinkCatalog.getobject(data_record_id_)">
        < ... display object stuff here ... >
    </dtml-with>
</dtml-in>

For testing purposes, I created another DTMLMethod in the same folder named 
'categoryName' and initially all it contained was one line:

Accounting

When I displayed the contents of my folder (which utilizes the list 
generation method),  I received a list of all objects which belonged to the 
category of Accounting.  I'm now trying to extend my code to use an actual 
category name specified by a user (or from a url clicked on by the 
user).  I changed my 'categoryName' code to look like this:

<dtml-with REQUEST only>
<dtml-if category>
    <dtml-var category>
<dtml-else>
Accounting
</dtml-if>
</dtml-with>

If I view this method, the result is 'Accounting', which is just what I 
would expect.  However, when I attempt to view my generated list in the 
same manner as before, I get no results.  I'm confused.  When the 
categoryName simply has the value 'Accounting' in it, I see results.  If I 
change the method to include some processing (but still answer the same 
thing), I get no results.  I'm sure that I'm just doing something stupid a, 
but it's getting late in the day and I'm not seeing what the problem might 
be.  Can someone help explain why I'm getting two different results for 
what should be the same?

Thanks.

I bet your ZClass inherits from either DTML Method or DTML Document, and
then the following article applies:

Is this comparison available?

Or going to be available?

kb

>>> From: Patrick Phalen <zope@teleo.net>:

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

I can't see the problem either, but I suggest changing your method to
this:

<dtml-if category>
  <dtml-return category>
<dtml-else>
  <dtml-return "'Accounting'">
</dtml-if>

The <dtml-with> is unecessary.  Note the single quotes inside the double
quotes.

This might fix it, might not, not sure.  But here you are explicitly
returning a string, not a formatted document.

Subject: [Zope] creator/owner attribute of an object? Mime-type of a file object?
Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AC@VRTMAIL>

I'm attempting to create a directory list (well, the final version will be
more complex, but this is where I'm stuck).  I'm looking for some way to get
the creator ID for all of the (file) objects in a folder.  I'm also
interested in getting the mimetype, but this is less critical.  Here's what
I have so far:

<dtml-in "PARENTS[0].objectValues( ['File'])">
url <dtml-var URL1>/<dtml-var id>
title <dtml-var title>
id <dtml-var id>
size <dtml-var size>
ddate <dtml-var bobobase_modification_time fmt="%m/%d/%Y">
owner 
mimetype <dtml-call "getContentType()">
</dtml-in>
<dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')">

Unfortunately, getContentType always seems to return null strings, and I
cannot find any attribute which shows the owner/creator attribute of the
object. If the creator is not available, the last editor would be fine.

Pointers appreciated,
Mike

Message-ID: <F32B7D6249C5D31187DB00C00D00F78C076EF8@weebo-2.osip.com>

Hello,

I've been trying to decipher the Zope member log in screens.  It appears
pretty straight forward.  There is the login.html screen which is basically
just a form for entering Name and Password and then passing this information
to logged_in.html.  I'll ignore the cookie for now.

logged_in.html then checks <!--#if "AUTHENTICATED_USER.getUserName() !=
'Anonymous User'"--> and reports success or failure.

However, as usual, there's got to be something I'm missing.  If I simply
build those two pages, the AUTHENTICATED_USER.getUserName()  check on the
logged_in.html page always return 'Anonymous User'.

When and how do I get the form to actually 'chat' with Zope and make me a
valid authenticated user?

Thanks in advance for any help provided.

	-mark

PS.

For those who are still having a problem with DCOracle and Oracle8i, that's
working great for me now.  If I can help, feel free to send me email.  I'm
running all this on RH Linux 6.1

I've been watching this debate since the begining and felt I'd put in one
observation on the above quotation. I actually think one of the comments in
this vain (maybe by ESR) was the goal for "software that sucks less" than
the whats out there. I don't think you can create software that doesn't suck
in some person opinion.

That said what I've learned is if I have to have software that isn't quite
where I want it to be I prefer the ability to adapt it myself. One argument
against open-source software projects is that they often come from amorphous
groups on the Internet. (Zope is an exception.) As a result there is no one
to "hang if it fails". What people don't factor into the equation is if I
have to pay $X for licenses from a vendor (with or without a support
contract) how many hours of contractor time will that buy me to install,
customize, administor, and maintain a freely available open-source product?

For those fighting this battle inside corporations I recommend
http://www.cluetrain.com as a place to visit.

That did the trick.  I hadn't thought about putting primes around a value

People are indeed working on Python, but not to the extent of more
popular projects like Linux or even, I believe, Perl.

Compiler/language projects have, historically, not thrived in the
collaborative world of open source software -- for very specific reasons
inherent in the concept itself of languages and compilers. Still, I'm
very impressed with the evolution of next-gen GCC (formerly EGCS).

I consider Skaller's Vyper project a fringe project with limited
applicability, because Ocaml itself is a fringe project -- it's
certainly not what you might call a mainstream, popular language.
There's something icky about an OcamlPython. However, I'd love for it to
succeed. (Unfortunately, Skaller is already out on a limb, implementing
all sorts of stuff he deems interesting -- so true CPython compliance
isn't necessarily on his agenda, and fragmenting Python like this is,
imho, not a good thing.)

Anyway, while I have not been monitoring the Python type/interface SIG,
it seems to be moving quite slowly.

I'm not saying they're holding back, but rather they're dismissing speed
and scalability as being a problem. I firmly believe that speed is
Python's number of problem today, and it's keeping Python from being
used in more applications.

Python has plenty of problems, but they're tiny by comparison and imho
they're mostly artifacts of Python's currently somewhat anemic syntax
(eg., only two kinds of loops, no "switch", no protected members, no
constants, no syntax for declaring mutability).

Imho Python's second big problem is what you might call, in lack of a
better term (I'm not wearing my compiler-writer hat right now, sorry),
contractual semantics -- anything from static typing (pass a string to a
function that takes an int and you get either a compilation error or an
exception) to interfaces (the ability to enforce semantic compatibility)
to design-by-contract constructs.

I disagree, but there's only one way to find out -- implement it (or
simulate it very carefully).

Not potentially. Definitely. I thought about this yesterday, and I got
to thinking that it would probably be pretty simple to create a dynamic
native-code generator that translated bits of bytecode on-the-fly, with
the necessary stubs implemented in a small helper-assembler written in
C. Something like:

  def Halibut():
    ...

  import codegen
  c = codegen.Translate(Halibut)
  c()  # Call native-code function Halibut

and then with whole modules:

  import pickle, codegen
  pickle = codegen.Translate(pickle)

Internally, Translate() would disassemble the bytecode, generating
native assembly language code and pass it to the helper C module, which
would store it in an executable buffer and fix up the necessary
references to the Py* API symbols.

Just a thought.

It would be an interim solution for certain CPU-intensive modules, in
anticipation of such built-in functionality in CPython itself. Possibly.

Well, I guess they're too busy arguing about whether Python should allow
assignments as expressions so you could do "while line = f.readline():".

Thanks,
The problem is fixed. The box with the ftp server had PARANOID host 
deny settings. This caused user's with incorrect reverse IP lookup
nameserver settings to be disconnected.
Sorry :-( 
You should all be able to download now (but maybe get in touch with
your domain administrator/ISP and get your DNS entries corrected, if
you previously had trouble ;-)

Cheers,

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * A Documentation Survey has been posted.  This survey will help
    Digital Creations decide where to focus our efforts by allowing
    you to tell us what you think about Zope documentation.

    http://www.zope.org/Members/Amos/Documentation/DocSurvey

  * "efm" has made a set of RPM distributions of Zope 2.1.4.

    ftp://www.tummy.com/pub/tummy/RPMS/

  * Maik Röder has posted an announcement regarding the Zope
    Documentation Project (ZDP).  Among other things, the ZDP has a
    new site.  It's a fantastic resource, and definitely worth
    checking out.

    http://www.zope.org/Members/roeder/zdp

  
New Products

  * Software Product: NFG Navigation Product, submitted by "gyst"

    Another product which provides navigation widgets such as trees
    and maps.

    http://www.zope.org/Members/gyst/NFGnav

  * Software Product: ZopeEDIT, submitted by "jimbag"

    This product allows you to edit DTML object from your Zope
    database in your favorite text editor.  Maybe.  Written in Python,
    so it just might work on your machine.  This is _not_ a Zope
    add-on, it runs on it's own.

    http://www.zope.org/Members/jimbag/ZopeEDIT


Updates

  * Software Product: mod_pcgi2, submitted by "phd"

    The update to 1.0.2 adds new documentation.  This is module allows
    Apache to communicate with long-running PCGI servers, such as Zope.

    http://www.zope.org/Members/phd/mod_pcgi2

  * Software Product: load_site.py with additional features, submitted
    by "Itamar"

    This is an enhancement to the load_site.py utility that comes with
    Zope.  It can be used to fill a Zope database with content from a
    filesystem.  This release, version 1.2, fixes all known bugs, has
    new features from the newest version of the original load_site.py,
    and runs in 'standalone' mode, loading into a remote Zope server.

    http://www.zope.org/Members/itamar/load_site/load_site1.2

  * Software Product: FSSession, submitted by "gaaros"

    FSSession allows you to store persistent, per-visitor information
    on your filesystem.  This update, to 0.3.0, fixes a number of bugs
    and properly supports Zope transactions.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: KM|Net News, submitted by Kevin Dangoor

    KM|New News is a weblog (news site) product, not unlike (but not
    identical to) Squishdot.  This update is version 1.1.

Zope.org items

  * How-To: Managing http/https URL Links, submitted by "rbickers"

    This How-To describes a clever method to generate links to objects
    which require different protocols (http or https).  This allows
    you to use encryption only where needed, without using exclusively
    absolute links.

    http://www.zope.org/Members/rbickers/http_https_ulinks

  * How-To: How to view all inherited and acquired attributes and
    methods of an object, submitted by "dmost"

    This How-To is essentially an educational (or debugging) tool.

Hi Matt, Hi Jack,

What were your IMAP/SMTP settings prior to setting them to localhost?
Were they empty or pointing to a specific host name?

Cheers,
Ryan

In my case, they were, for IMAP, my local machine name, and for SMTP, my
ISP's (Roadrunner's) SMTP server.
IMAP has always worked great.  SMTP has been the problem.  I have not tried
Jack's solution, as I can't use localhost
for SMTP.

Thanks for any help,
Matt

I am getting a strange error when I try to access the Properties tab of
one of my objects called "News":

ErrorType: InError
ErrorValue: Strings are not allowed as input to the in tag.

The traceback is as follows:

Traceback (innermost last):

    (Object: getProperty(id))
InError: (see above)

What does an error in the input to an "in" tag have to do with accessing
the properties tab?

I could be wrong, but I suspect that this has something to do with an
assignment I made to a lines property that belongs to the "News" object.

Something to the effect of a string being assigned to a lines property?
(I make this assumption because I have had this error come up before
with lines properties. In this previous case, I just flushed out the
contents of the lines property in question using
"manage_changeProperties". This fixed the error, although even then I
never understood what the error in input to an "in" tag had to do with
the lines property value being erroneous.) As I no longer need this
property, I would gladly eliminate it. However, Zope won't even let me
in to the Properties tab. It just displays the "InError" when I attempt
to go to Properties of the News object. I can't really remember the
exact wording of the lines property id so I can't delete it via
"manage_delProperties" or flush out the contents of the property using
"manage_changeProperties".


Any insights as to what is going on and how to resolve this situation?
Please excuse the verbosity of this posting.

Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AD@VRTMAIL>

I know, bad form responding to one's-own post, but I did figure it out and
thought other newbies might find it useful...  The first (trivial) problem
was that I had a typo (dtml-call instead of dtml-var) which prevented the
content-type from displaying.

"type" "<dtml-var "getContentType()">"

The creator/owner attribute can be got at by going through the
get_local_roles method then searching for a value that has "Owner" in it,
and copying the corresponding key.  I'm sure my dtml is atrocious, but hey,
I just learned it this afternoon :) .

"owner" "<dtml-in expr="get_local_roles()"><dtml-let
temp=sequence-item><dtml-if expr="temp and 'Owner' in temp"><dtml-var
sequence-key></dtml-if></dtml-let></dtml-in>"

Enjoy all,
Mike

Having a slow machine, not having to restart the server when testing is
important for me (it is a 20 second start up for me).
Is there a script around to let me do this... ?

Here is what I have done so far (using bits of snippet from the source):

log into the monitor, and do this:

import Zope
app = Zope.app
c=app()
OFS.Application.initialize(c)
c._p_jar.close()
del c

The net result is all items in the the "Add New Item" combobox double up,
and I am not even sure if this does the trick...

Good idea. Zope needs some more languages anyway.
Apache for example has mod_negotiation for this.

please not: the q argument is not meaningless.

I think a better way would be to implement a true negotiation mechanism.
That is, if the request comes, zope has to look for languages available
and rates them according to the language preferences coming from the UA.
Then it sends out the highest rated document, that might be the first
of the items in accept-language.
So each document (could be a folder?) schould have an attribute to
identify
its language capabilities. 

A simple branch would imply you have all documents in all requrired
languages.
I in doupt you can make this happen.

Easy with a second string.split(_.['sequence-item'],";")[0]

Subject: [Zope] Documentation survey
Message-ID: <14534.58177.603725.668441@antares.int.plain.co.nz>

As the tiny little text box on the survey page isn't up to long
dissertations, I'll post my comments here:

The guides need better examples and blank spots filled in, in
general. The DTML guide, in particular, needs a canonical explanation 
of the quoting rules and shortcuts so new DTML hackers understand why
you can get away with this:

<dtml-let foo=bar> ... </dtml-let>

But still need to do this:

<dtml-let foo="'constant'"> ... </dtml-let>

There is still a lot of docs using the old, ugly HTML comment style
tags, too, which is confusing, and there are a lot of examples of
using '_' and REQUEST to kludge up a temporary namespace when
<dtml-let> is the accepted means to kludge up a namespace[1].

The HOWTOs and Tips are potentially the basis of an excellent Zope
cookbook, but they require more stewardship from DC:

- They need more structure. Catagorizations like
'Authenication/Authorization', 'Using RDBMSs' and 'DTML tricks' would
save a lot of search time and provide hints towards missing
documentation. 

- The need to be vetted. There are a lot of docs with incorrect
examples and obsolete information that need to be tidied up. 

John

[1] Who the hell came up with a scoped assignment tag?! Why not
implement a <dtml-set> tag that isn't a container and that assigned to
a temporary namespace that persists for the duration of a DTML objects 
rendering. It can have a special attribute that you use to commit
changes made to an object in the temporary space back to it's
persistent name space, and you'd have a decent assignment tag.

It is the name of a method that will be called when the File is accessed.
You can use it for checking a session cookie, or anything you need from the
REQUEST.

If you then want to deny access to the resource, because your precondition
hasn't been met, the method can raise an exception.

I dont know if this is possible, but one feature of any tree-transformation
language that might be usefull to me would be the lazy construction of
nodes, or the creation of a virtual tree that is in fact a live view of the
source tree. XSL seems to be designed as a batch-processing language, which
seems at variance to the principles behind zope.

fmt="..." accepts any printf style formatting string.  Grab your handy C

No, sorry.  Python has a 'reload()' built-in, maybe that could be

Message-ID: <4.2.2.20000308192207.00e638e0@127.0.0.1>

I'm new with Zope.

One thing I'm looking for how to do is the effect that one document might 
virtually be stored in multiple folders.

For example, if I keep a hierarchy of folders that is an archive of 
articles, maybe stored chronologically in a folder for each month or 
something like that. But then I also want those same articles to appear in 
other folder hierarchies, categorizing and organizing them in various ways. 
And I don't just want to put duplicates of the document in there. I'd like 
that if somebody updates the original, the virtual documents in the other 
folders update too.

Is there some obvious DHTML statement or trick I don't know about yet? Or a 
Product that does something useful about this? Essentially I'm looking for 
an equivalent to symbolic or hard links to files in a Unix file system.

Subject: [Zope] what defines the absolute_url() prefix?
Message-ID: <38C72738.F8CB3EB8@picknowl.com.au>

G'day,

I'm having a blast using (technically: playing with :-) Zope 2.1.4 on
a RedHat 6.1 box, and mod_pcgi2 (1.0.1).  For my first efforts, I've
built a set of DTML methods which emulates www.python.org's style of
website, with an index_html method that "includes" Banner, Sidebar,
Body etc methods, which can be over-ridden in lower-down folders. 
All funky stuff, works well.

In the Sidebar, I have links to folders within the site using
absolute_url() (because of issues with BASE HREF giving me multiple
folder syndrome).  I can access the folder with the URL
http://localhost/cws/Help (and the logfile shows "GET /cws/Help"), but
the absolute_url() method on cws.Help is actually returning
"http://localhost/cws/cws/Help" (which is also accessible - kinda odd,
but not what I want).

I kinda suspect I've screwed the mod_pcgi2 config, mainly because its
the area I'm the most confused about :-)  I have the following config
in Apache:

<Location /zope>
    SetHandler pcgi-handler
    PCGI_ROOT /
    PCGI_SetEnv SiteRootPATH /
</Location>

<Location /cws>
    SetHandler pcgi-handler
    PCGI_ROOT /cws
    PCGI_SetEnv SiteRootPATH /cws
</Location>

(Oh, and I've just added a <dtml-var REQUEST> to the Help page, and
it's returning URL http://localhost/cws/cws/Help/index_html for
accesses to http://localhost/cws/Help, so it's awfully consistent
in its behaviour.

How does zope determine what the prefix is, and better yet, how do I
fix it to mesh with reality?


Regards,
  Daryl Tester

Flemming,

What you have described is exactly what Acquisition does.  Say you put a
document 'DocumentFoo' in your root level folder.  You could access that
document a number of ways:

/DocumentFoo

/AFolder/DocumentFoo

/AFolder/AnotherFolder/DocumentFoo

this happens for you automatically right now.  Try it youself, create
some folders, put a document somewhere 'above' them (like in the root
folder) and it will work.

Subject: [Zope] fast cgi
Message-ID: <003b01bf8988$d50e3960$0402a8c0@toil>

Exactly how do you get zope to work under apache with fastcgi?

I found 2 documents on the zope site dealing with this issue and they both have
command options "-pass-header Authorization" like
FastCgiExternalServer /home/httpd/html/z -host localhost:8999 -pass-header
Authorization

This produces an error as an invalid option, and looking at the documentation for
the FastCgiExternalServer directive it is not an option. The version of fastcgi
is 2.2.2 which is the same version they say to use in the documentation.

Does anyone besides Digital Creations know how to make this work? I have tried
this a bazillion ways from apache rpm's and binaries, but can't get it to work.
Someone must know how to do it.

Thanks

If you look around at Zope.org, you'll see that most content physically
resides in Member folders. But the same content can also be found through
the Documentation, Products and Reosurces pages.

We use the ZCatalog for this. You can build up pages with searches, thus
allowing multiple views into your content.

We are currently developing a thing called 'Topics', they exploit this
feature in an automated way. You specify a search on them, and they will
thus model a view into your indexed content. This way you can generate pages
with your articles by month, or by topic.

I think he typoed 0.2.3 instead of 0.1.2. 0.1.3 is out as of today (or
yesterday), but shouldn't offer any improvement in conjunction with Zope,
so you don't need to rush out and get it.

The main hurdle that people installing MySQLDA with MySQLdb seem to have
is, they want to try to compile the stuff in the src directory that
ZMySQLDA provides. This is MySQLmodule, which is the old interface. Just
rm -r src. There is a patch that comes with MySQLdb that needs to be
applied to ZMySQLDA. Once you've done these two things and installed
MySQLdb on your PYTHONPATH, you just need to restart Zope, and make a
ZMySQLDA Connection object (or whatever it's called).

I don't think a new syntax should be brought about. There are too many things
to learn already, it will only add to the confusion.

I do agree that dtml is complex and something needs to be done about it.
Probably a subset of the current dtml itself - with minimal additions which
make somethings easy - would be good.

Also (if this is seriously being considered) I would favour for a somewhat
different paradigm:

Instead of:
> <var object="layout.table_header"/>
> <in object="get_above_age" arguments="age">
> <var object="myrecord" arguments="in_item"/>
> </in>
> <var object="layout.table_footer"/>

We could have:
<dtml-var object="layout.table">
<param name="datasource" value="get_above_age">
<param name="columns" value="Name,Age">
</dtml-var>

The advantage here is that:
   o   One logical presentation element (a table) is one element in dtml code.

   o   One-to-one relation is possible between the code and any GUI entity
        being used to design (think ZStudio). This means the layout.table can
        be one icon that is dropped into a design view and it's parameters
        specifed through some fancy widget. 
        Also when the code is stored and reloaded, it would still be
        possible to display the same GUI entity in the design view and it's
        parameters would be editable.

Discussions on the above have taken place on the ptk and zope-moz lists.

That is a very peculiar error. Py_InitModule3 is a symbol from Python
itself, so if that's missing, I don't know what's wrong. Well, I can guess
a little, and my guess is, while you have Python installed, you don't have
the development libraries. With RedHat, this is python-devel, but may be
something else with Caldera. Actually, Py_InitModule3 is a macro in
Python.h, so if it's looking for that, then Python.h is probably not being
found, which could mean that the -I flag in Setup (or Setup.in) is not
right for your environment. But you would have all kinds of build errors,
I would think.

Try this:

find /usr/include -name Python.h -print

If nothing comes up, then the development stuff isn't installed, or it's
installed somewhere else.

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Subject: [Zope] Zope Question : Virtual folders / URL's
Message-ID: <009301bf89a9$afced7b0$0201a8c0@iridium>

Have been reading the docs but still not clear on a few things.

I have my site mapped out in my mind. It has URL's like :

mysite.com/          (main page)
mysite.com/rss     (rss content for mysite)
mysite.com/<username>  (main <username> page)
mysite.com/<username>/rss (rss news content feed for <username> page)

Where I come from data belongs in a database. I'm happy for all my HTML to
be in the ZopeDB but not any application data (users definitions, news items
etc etc).

So, looking at my URLs I see that there are a mixture of static and virtual
folders.

mysite.com/index_html is obviously static though it contains dynamic
content. Doing this with Zope is easy and obvious.

mysite.com/Fred/ is a dynamic page. Fred only exists as a username in a
users table and related information in other tables. It's not obvious to me
how I go about serving this page because I can't create a static page for
every username (nor do I want to).

Clearly mysite.com/Fred/rss will use almost identical processing to the
mysite.com/rss page, just different parameters so re-using my "rss"
generating code is important to me too.

I'm know these virtual folders can be served up by Zope. Can someone tell me
what I am missing?

Last I heard about this, the status was "Not available".
http://lists.zope.org/pipermail/zope-ptk/2000-February/000323.html

But soon (hopefully!), I'll be releasing iTrack - an Issue Tracker Zope
Product. I haven't really used the ptk tracker so I can't give a comparison.

Well, it's a "feature" I can live with (otherwise it wouldn't be working
at all :-).

Tried that too, no joy (with all possible combinations of PCGI_ROOT and
PCGI_SetEnv, as I don't exactly understand its affect on Zope itself).

The dump from the REQUEST Session state shows (for both settings of
PCGI_SetEnv, plus some judicious editing):

URL:		http://localhost/cws/cws/Help/index_html
URL0:		http://localhost/cws/cws/Help/index_html
SERVER_URL:	http://localhost
REQUEST_URI:	/cws/Help
PATH_INFO:	/cws/Help

SiteRootPATH: changes (from /cws to /), so that's something.  :-)
From an environmental point of view, things appear OK (but what
would I know, I've only be using Zope for just over a week).  I'm
not sure how absolute_url() is constructing the full URL, but I guess
it would be from those above components (there doesn't appear to be
anything that defines the absolute hierarchy that I can find).

On a whim, I tried http://localhost/cws/manage, and the urls on that
page suffer the same problem too (eg, in the left hand frame there are
links of the form "http://localhost/cws/cws/Help/manage_workspace").
At least it's not just my DTML methods. :-)

Subject: [Zope] Indexing dtml/html files
Message-ID: <v04205508b4ed3dfc6467@[130.227.115.35]>

Hi,

Is it possible to use catalog to index ordinary html pages intelligent ?

If I have a html(dtml) file like:

<HTML>
<p id=title>
Are you Intelligent ?
</p>
<p id=author>
A. Einstein
</p>
</HTML>

I would like to index the title and the author id's, for which I could search.

Is it possible ??

   Well, let's me clarify a bit. PCGI_ROOT is the folder (or other object)
in Zope which will serve your requests. In your situation it is folder
"cws" in root folder.

   PCGI_SetEnv is *only an example* of how to set per-request environment
variable. Whatever variable you'll use and what value to set - it is up to
your configuration. In my example it is variable SiteRootPATH.

   This variable only works with SiteAccess. I use SiteAccess pretty
happily, and it solves all my virtual hosting needs, including rewriting of
BASE, absolute_url, etc.

   Without SiteAccess you'll get exactly what you get - additional path
components.

expand_all and collapse_all are all very well but I think Andy is after the same
thing that I gave up on. 

How can you expand or collapse a tree to a specific point, ie:

- make a particular subtree expanded 

- make sure a particular node in the tree in visible

The Zope DTML guide mentions the tree-s, tree-e and tree-c variables but it
doesn't explain how to use them. I haven't found any help anywhere on this.

Any ideas?

That's true, but that shouldn't hold us back indefinitely; some things are
can only be improved after a while if they're redesigned from scratch, 
otherwise the back-compatibility issues become too complicated. I don't know
if DTML is at this state though, and any new language proposal should be 
something to consider for the (very) long term.

But you lose some flexibility in defining table headers and footers;
you have to be careful your simple language becomes too rigid, making
too many assumptions.

Hm, what you're proposing is some higher level object (a product) that
does tables (in this case). That would in fact be rather neat.. Our simple
glue language could become extremely simple if we have sufficient higher
level components, and if it's easy enough to code up your own components.

I'm doing something like that for web forms in my ZFormulator product.

Okay, this kind of discussion probably belongs on another list, I agree. :)

I guess you could do it in XML-documents, that are
inherently more machine-readable than html..
Otherwise, storing title and author in properties would
do the trick for zcatalog..Not exactly what you ask for, but
as close as i can get with my skills..
I guess you could write a pythonmethod to extract title
and author from the html and store them in properties so
that they could be easily indexed..

Usin tree-s/c/e is going to be a bit problematic.

In my understanding those vars are built from the context of the node in the
tree, so if you add/remove anything to/from the tree then the tree-s/c/e
will change.

There doesn't seem to be anyway of going to a particular point in a tree
with any certainty.

I did this on one site for example, it's a prospectus for a college, the
tree is built from calls to a sql database.  Adding or removing records from
this database totally changed the tree-s/c/e vars that each node is
associated with.

I hope I'm wrong about that but I have a horrible feeling that I'm right.

Please someone prove me wrong.

actually I do have xml documents also but it is for an automatic 
system where the upload is done via webdav or ftp. So I need a way to 
upload Zope xmldocuments from a client.

I am not a Python programmer and would rather find a solution without 
doing some coding. But I have found the urls to find and update the 
index from the client. But now I need to upload xml documents to Zope 
AS xml documents. Is there an easy way to this ?

I don't know enough about Perl to judge this, but to me, there's
plenty of activity out there. Of course there could always be more,
but lots is happening.. We have _three_ independent implementations of
Python, for instance (Python, JPython and Vyper, and then there are
projects like Python2C).

Sure, it's not easy to do. I would debate that compiler/languages have
not thrived in the open source world, though. There seem to be
quite a few successful open source languages around.

[assessment of Vyper with which I agree]

That's the nature of discussion lists, almost. There are some prototype
implementations of type-checking systems for Python, though (I think
two or three independent ones, in fact).

Hm, but in my experience Python has been shown to be plenty fast enough
for the majority of applications. You're probably right though, and I
agree completely that a faster Python would be very nice.

I suggest you go discuss these things on comp.lang.python. :)

I don't miss switch. Functions are first class objects, and dictionaries
can be used instead of switch when necessary. Also, good object oriented
design tends to kill switch statements anyway.

I think the two loops are fine, though it would be nice to have the
current constructs to know about iterators. I believe Guido is
taking that into consideration. Also there's the list-comprehension
proposal which may help here. 

I don't think you'll see protected members any time soon.

I'm not sure what you mean with syntax for declaring mutability, though
it sounds interesting.

The types-sig is reaching consensus about optional static typing and
Guido does want to include that into the language in the future (beginnings
in 1.7, full implementation in Python 3000 aka Python 2). Interfaces are
being considered too, and Jim Fulton in fact has an interfaces proposal
out there (that may get used in Zope's code base).

I think using a unit testing framework can substitute for design by 
constract constructs myself.

Okay.

[snip code generator extension idea]

Something like that would definitely be neat. The hard part would be
in the translation process, of course. The other part is in the
interfacing with regular Python; do you allow your translated function
to refer to other Python objects? If you do, you're opening a can of
worms. If you don't, then it starts to look like the 'Swallow' subset
of Python I proposed once; a strict subset of Python with added full type
annotations, which is translatable into C or native machine code.

If you're starting such a project I want to hear more about it!

Not to mention indentation! Anyway, the people who keep bringing these

PCWeek did a shoot-out of various CMS packages about six months ago. 
They created a "scoresheet" that might be useful.  Unfortunately,
Vignette stood by their policy of not allowing their software to
reviewed, so it includes several other CMS packages.

Message-ID: <4.2.0.58.20000309114320.01881df0@192.168.0.2>

Hello Darran,


building on Rik's previous answer, how about this:

   <dtml-call "REQUEST.set('myObjRef', _[desired_id])">

It tested OK with an Image object called "image" and located in the site root:

# Storing the image name in a variable
<dtml-call "REQUEST.set('desired_id','image')">

# Creating an object reference based on the variable
<dtml-call "REQUEST.set('myObjRef', _[desired_id])">

# Displaying the object title and size
<dtml-var "myObjRef.title">
<dtml-var "myObjRef.getSize()">

# Rendering the object if it's renderable. An image is.
<dtml-var myObjRef>

If it's not renderable, you'll end up with something like "<Folder instance 
at 01368880>" in the HTML page source code.

Does it work for you? If yes, you may want to add a FAQ Question and it's 
Answer on zdp.zope.org (hint, hint :-).


Cheers.

The answer in my case is both.
My test box is called "geezer" so initially it was set to "geezer". This
designation works with other IMAP tools (ishmail, Netscape). When this didn't
work I tried the FQDN: geezer.lab.jacku.com (My exposed FQDN is different due
to masking by the cable modem company.) This provided a similar error. Reading
the doc files I decided to leave the fields blank. This also generated an
error. (I don't remember at this point if it was the same exact error.) After
that failed I entered local host for both options and it worked. This became
the "last test" since its result was positive.

Hope this helps.

Hi Folks,

I sometimes et the strange and quite inconvenient problem that the
treeview of the manage interface gets spacing of a few cm's between the
(+) sign and the folders on any folder below the 2nd level. The result is
that the tree is quite wide. Does anybody else have this problem?

It seems to be happening if more than one or two branches are expanded,
but I haven't pinned the exact problem down yet. I use 2.1.4,
debian-packaged zope. Is this a known bug, can I help in some way in
tracking it down?

If there is a 'multiple select' on the property sheet with no value
initialized, you can get this error.  This seems to be a long-running
bug with multiple selects.  At the moment, it is important that the list
(or lines property) has values before creating the multiple select, and
then you must establish a value for any new multiple-select by selecting
one or more of the items in the multiple select as soon as you create
it.  I think the bug is in the collector, but I cannot be sure.

HI,

In the python interpreter I have done the following things:
>>>import sys, ZODB, ZODB.FileStorage
>>>db = ZODB.DB(ZODB.FileStorage('/usr/local/zope/zope214/Data.fs'))
>>>root=db.open().root()

Where 'Data.fs' is my Zope DB with a lot of stuff. Then I did the following
things:
>>>root.__dict__
>>>{}			#result of the previous "command"
>>>dir(root)
>>>[]			#result of the previous "command"
>>>vars(root)
>>>{'container' : {}}	#result of the previous "command"

I expected to find the stuff I have in my Zope DB. I double checked to look if
I didn't made a typo on the longname of my Data.fs file, but all seems ok. I
also saw that the modification time of Data.fs.lock and Data.fs.tmp were set to
the time I run db=ZODB.DB(....... so I guess I chose the right Data.fs file.

Can someone tell me where am I wrong?

Thanks

Hi,

When I have a form with a <textarea> field set to submit to an sql
method, ['it gets stored','like this']. How do I get around this? Do I
have to do some special formatting before submitting to the SQL method,
or is there something I must do in the SQL method declaration itself?
I'm using <dtml-sqlvar fieldname type=string> because this was the best
I could find in the documentation. Is there a type=lines? If there is,
someone please put it in the ZQR.

Another: I want a text holding ZClass for storing text pages. Deriving
from DTML Document or Method seems the obvious choice but I have an
issue with that: the content must be rendered thus:

<dtml-var standard_html_header>
<dtml-var raw newline_to_br>
<dtml-var standard_html_footer>

I suppose I have to override rendering for my ZClass and insert this
code. How do I do this?

Hmmm....

Very interesting, I agree that installing Zope on Win* was very easy. The
problem I have is how to Sync stuff between my local Zope at home (no net
connection) and the 'real' Zope at work.

I currently do an export to a ZIP disk, and then an import back into the other
Zope from the disk. This makes a lot of things possible but only in very limited
circumstances:

You have to move *all* of Zope, or objects don't re-import back into the correct
place. Also, if an object changes on the 'real' Zope changes while I'm at home
and I import when I get back, the changes are lost as my import overwrites
whatever is there...not pretty.

Also, I can't do this trick with things like Squishdot postings, which is a
shame...

What would be nice is something like Lotus Notes replication when you import a
.zexp file; you get a replication conflict if both objects have changed, which
you can then sort out.

I'm not looking for the full-blown ZEO distributed object store, just a way to
periodically sync a set of selected objects (slightly more complex in the
squishdot case...) by exporting from one and re-importing (non-destructively)
into another.

Any ideas?

Hi,

  Is there any way in Zope to validate information
(news, new document) by third party before real
publishing.

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  How can I do this kind of things with Zope? Is it
possible?

  Any suggestion? links? help?

Message-ID: <4.2.2.20000309104029.00be1b50@saladin.aisys.com>

I know that there have been several threads on this list concerning the way 
to pass arguments to a DTMLMethod.  I've done what I think is correct, yet 
my result is less than pleasing.

Here's what I have and what I'm doing.  Hopefully someone will identify 
what I'm doing wrong.

In my web sites root folder (aka /Foo), I have a DTMLMethod named 
"siteRoot".  It simply answers "Foo".

In a subfolder of Foo, I have a method named "linkFor".  The code for this 
method looks like this:

/<dtml-var siteRoot>/SomePage?option=<dtml-var optionValue>

In the same folder that contains the "linkFor" method, I have another 
method which wants to use the result of the "linkFor" method.  In this 
method there is a line which looks like this:

<a href="<dtml-var "linkFor(_, _.None, optionValue='some value')">">Some 
Text</a>

When this code gets executed, I get a "KeyError" on "siteRoot".  For some 
reason, when my linkFor method executes, it can't see the siteRoot method, 
even though the method exists in the parent folder.  What am I doing 
wrong?  Why can't linkFor see siteRoot?

Thanks.

Message-ID: <NDBBLENPLCPAHKODFHNGMEHKCNAA.morton@dennisinter.com>

I have never seen the Python interpreter crash in any way, nor have I heard
of it doing so. I havent seen this, but my partner tells me he as seen the
Perl interpreter crash. I have seen the Java JVM crash many many times. Some
of my Python code has been running 24/7 for the last 18 months.

I would say that, as languages or interpreters, Python and Perl are equally
and extremely stable. As tools for developing software, Python's object
oriented foundation is conducive to the building of more stable _systems_
that Perl. This could be because of the language itself, or because of the
programmers it attracts.

Most of the Perl programmers I have met are, frankly, obscuritan mess-heads.
The concept of structured programming is somewhat anathema to the Perl
programmer. I looked over the shoulder of one Perl programmer we had hired,
who was having trouble with a database import problem for several weeks.
This Perl programmer had written 6 pages of perl code without actually using
_any_ indentation. The program was full of nested loops and she was having a
difficult time debugging her code. Without knowing any Perl, I cleaned up
the indentation, fixed a few glaring problems, and handed it back to her.
She had the problem solved at the end of the day.

It comes down to this: It is hard to write a program in Python that another
Python programmer (or the same programer several months later) wont
understand. It is easy to write a program in Perl that another Perl
programmer wont understand.

As for the outside consultant. Ask them what makes them feel that Python is
less stable than Perl, and what exactly that means.

   There are mnay ways you can do it. Publish it in some hidden location
and later move it into public area. Use Versions. Develop your own
mechanism for publishing...

  Is there any way in Zope to validate information

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  Any suggestion? links? help?


[RH] There are several ways to accomplish this:
You could put the document in an 'incoming' folder and make a reviewer move
it to the publishing location (this also allows for letting the reviewer add
keywords/categories etc).

If the uploaded document goes directly to the documentation where it is
published, you could give it a property called 'approved'; reviewer invokes
dtml method which sets the approved property to 1. The document is not shown
unless the ' approved' == 1.
[untested simplistic dtml]

<dtml-unless "approved==0">
   <dtml-var <document>>
</dtml-unless>

I believe the Squishdot product
(http://www.zope.org/Members/butchland/Squishdot) allows for something like
this.

A third (more sophisticated) possibility is to combine the two approaches by
using the Catalog, more or less like the Zope site does:
contributions by members are submitted for approval to the Zope site
administrators, who then add them to the site's catalog. Then they are
available in pages that use the catalog for their contents (like the howto
pages, the products pages etc). In your case reviewers could also add
keywords/categories etc to the document before it is cataloged and the
catalog may index these. I do not think the Zope site approach is available
for the public, but it shouldn't be too difficult to implement it.

A related product is ZDP tools (http://www.zope.org/Members/roeder), which
does not exactly do this but may be a source of inspiration for workflow
management. Another workflow system in Zope is Xen (I do not have the URL
handy right now), but this may be overkill for your needs.

Hey James,

Just in my experience I have never had a problem with the stability of
either Python or Zope. I have set them both up on multiple servers (RH 6.0,
6.1) and been pounding away at them for months now. Python 1.5.2 has been
out of awhile (a year?) and Zope releases are certainly stable. In fact,
having been using Python for web CGI scripting for 4 years now I have never
had a problem with the stability of it as a language (run it on NT, Mac,
Linux and Solaris boxes). I usually just build it and let it leave it, never
needing to look back till I am ready to update it.

2 folders are next to each other, one is called test1 the other test2. They
are within the same Home folder, but one is not within the other. Can an
index_html document in test1 grab a dtml-var from test2? How is this done?
In html i would simply write ../test2/dtml-var. This does not work in Zope.

Message-ID: <v04220803b4ed7c0e4906@[192.168.0.16]>

I can confirm and reproduce this problem, and on a totally different 
architecture - Red Hat Linux system with Zope 2.1.4. Here's a snippet 
from my /var/log/messages file:

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- -
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782


Notice that the timestamp from the syslog facility is the correct 
local time, March 8 10:14:18, which is Pacific Standard Time. On the 
very same line, the timestamp passed to the syslog from Z2 is in GMT, 
08/Mar/2000:18:14:18 -0700. My guess is that Zope isn't picking up 
the $TZ environment variable. What I don't get is why it's showing 
GMT as 18:14:18 -0700. That would imply a local time of 11:14:18. I 
think it should be 18:14:18 -0800 right now, and -0700 during 
daylight savings time. Two, two, two bugs in one!

I think you are safe in classifying this statement as FUD.  I've been
using Python (outside of Zope) for five years.  I even had a non-trivial
accounting system that my business depended on running in Python.
A bad design decision on my part led to some real problems with memory
size and CPU use of the resulting program, but Python never crashed
no matter how much data I tried to shoehorn into my badly designed
system.  Python is rock solid.

So does KM|Netnews (available on the products page on zope.org).
If it doesn't meet your publishing needs, you might want to look
at its code to see an example of a way to do it.  (I haven't looked

I have a simple two field table in MySQL, "whowhat", that pulls a user id

"what" classes)

I , being somewhat new to python & Zope, am having the darndest time trying
to do a simple external method to do a count of how many times the class
"so-and-so" is in the table. (That way, I know how many people have
signed-up, and how close I am to the class max.)  I have tried different
searches.  I have an SQL Method that does:

select * from whowhat

And I also have one that does:

...
select * from whatwhat where classcode = <dtml-sqlvar class_name type=nb>

I've been trying to create an External Method, but I just can't seem to get
it to work. (yes, in the Extentions directory)

I need to try to stay away from doing a "select count(classcode)..." in an
SQL Method if I can.

Any help to this tormented soul would be greatly appreciated.

<dtml-var "parents[1].test2.index_html">

would get index_html from ../test2 in a dtml document in ../test1

<dtml-var "parents[0].test2.index_html">

would get index_html from ../test2 in a dtml method in ../test1

There are other postings on why there is a difference between documents and
methods if you care...

Subject: [Zope] Having slight problems with <dtml-calendar>
Message-ID: <3.0.1.32.20000309114825.00698938@bizux.net>

Problem:
  Currently I have no problem view the HTML tables of the calendar or
adding properities. Where my problem lies is displaying those properties in
the tables of the calendar.

Currently the variables for the date, whether the object has a property,
and the value of that property are registed just like the <dtml-calendar>
How-to.

<dtml-let d="date.Date()"
          hasdate="hasProperty(d)"
          dprop="getProperty(d)">

The 'd="date.Date()"' does what it is supposed to. (make d equal to
something like 2000/01/17). I checked the hasdate variable and found that
it was equal to a 0 (1 if true, 0 if false, of course).

The properties are kept on the folder, where the calendar method is. I
added a property via the method for doing such and went back and checked
the folder to see if it had a property on it. Yes it did... in this format.

Tree Structure:    /diis
                     /calendar (contains the properties)
                       index_html (displays the calendar)
                       /updatecalendar
                         index_html (used for editing the properties)
2000/01/17 This is the 17th day of January.

Yet, hasdate was equally 0 (false) therefore the 'dprop' value could not be
set.

I guess my question is this:
  If the folder containing the calendar method has properties on it which
are   to be read into the tables of the calendar, does this mean that
'hasProperty(d)' is not being read off the folder and is looking at some
other object for the value?  

If that is not the question can someone please point something out to me
that I am doing wrong...

All help is extremly appreciated.

Best regards, 

Mark J. Stahl

The testamonials continue...

I wrote a perl app a few years ago for a customer, about 10,000 lines.
It produces a book in postscript from a database of info. They run it
once a week. It crashed at random. After 6 months, I couldn't read my
own code, comments or not. I ended up rewriting in Python and it has run
without a hitch for about 2 years AND I can still read and understand
the code. I hesitate to write a thing in perl anymore, and if I am
forced to, won't support it. I've had Zope and numerous other programs
in Python running without one crash EVER! Believe it!

It really depends on how bad your intentions are. Could you use
subclassing? Or do you want to add methods dynamically after instance
creation?

I am not sure what you mean by dtml-var but I assume you want to access
some attribute in test2. You can make test2 attributes accessible in test1
by:

<dtml-with test2>
tarari tarara
</dtml-with>

Message-ID: <20000309110821.A2683@devware.com>

I have seen a couple of people mention zope lockups on here before and
I haven't seen any myself until just recently.  (I have zope on about
5-6 machines and this is the first time I've seen this happen)
Anyway, how can I diagnose this problem?  So far I have only seen it
happen twice, but it was twice in the last 24 hours, and I'm getting
ready to roll out this app to some users.  I'm concerned!  Anyone have
any suggestions?

Symptoms are basically that it just stops responding.  The web browser
seems to connect, but it never completes the connection.  Right now I
have it running in debug mode to see if I can catch whatever it is
with some console logging.  This is on an NT Server running NT 4.0

I believe you have to supply the (_.None, _)
parameter for the index_html method to work.

You are ALMOST ALWAYS better off using the
<dtml-with ...> tag, something like

<dtml-with test2>
  <dtml-var a_something_inside_test2>
</dtml-with>

Or in the more general case of many layers

<dtml-with "FolderA.SubFolderB.SubSubFolderC.test2">
  <dtml-var methodA>
</dtml-with>

This pushes test2 onto the namespace stack. So
your methodA can still access objects inside
the SubSubFolderC.

------------------------------------------------

Use the dotted notation, e.g:

<dtml-var "F1.SF2.methodA(_.None, _)">

only if you don't need any objects from the
subfolder F1.SF2 during the call. Most of the
times, this is not what you want.

In this case subclassing won't work and I'm not needing to do this

Subject: [Zope] Finding crash information
Message-ID: <m37lfcawfm.fsf@wacko.pdx.net>

I'm having a serious problem with my Zope server running in
production.

Platform: RedHat Linux 6 (2.2.12-20 kernel)
          Python 1.5.2
          Zope 2.1.4
          starting with: python z2.py
                         as root/nobody on port 80 straight ZServer


Under load (not too heavy, but busy) the Zope process SILENTLY stops.
I get no traceback info anywhere that I can see.  Nothing to
stdout/stderr, nothing in Z2.log.

If I start as: python z2.py -Z '' to prevent the fork and detach I
still get no message when the crash occurs.  

I can't run this in DEBUG mode because I'm using GUF cookie mode to
authenticate and the login screen ends up showing an exception error
(by design?)

If anyone can tell me how to run in DEBUG mode but make GUF still hide
the exception error that would be a big help.

If anyone can help me keep this server from crashing every forty-five
minutes I'll buy 'em a beer next time they're in Portland.

-Jon

BTW, the site is very non-exotic.  GenericUserFolder with a lot of
static content and one ZCatalog w/CatalogAware ZClass.

Let's say in Zope you have SQLMethod whowhat and SQLMethod whatwhat.  In
your external method you should simply be able to do:

def countWhoWhat(self):
  return len(self.whowhat())

def countWhatWhat(self, class):
  return len(self.whatwhat(class=class))

These should return the result count for each SQLMethod.

Now, I now I can do this using JavaScript on client side, by doing something

MyFunc()

form.submit();

}

So is it possible to do this without JavaScript ?

I never had any problems, but then again, I'm not sure I've ever done this with
index_html, or in quite the way you describe.

Done it lots with calls to SQL methods and other DTML methods, but I don't think
they reference other objects themselves...

Hi all,

I have built a trivial ZClass : CD (from CDProduct, from the guides).

I try to add a DTML Method "render_short".
This method would render the CD Instance on one short line.

My ZClass has simple attributes (artist : string, title : string,
description : text)

I would like to be able to write this simple "render_short" DTML method like
:


Artist : <dtml-var artist>
Title : <dtml-var title>
Descr : <dtml-var description fmt="structured-text" newline_to_br>

But when I insert a <dtml_var myCDInstance> in my index_html, I got a
exception :

Error Type: KeyError
Error Value: artist

There is no typo in my code...
How can I access to my ZClass instance attribute from inside its methods ?


Please help me :)

Olivier

Is this a pure Python question? (Zope External methods
are VERY different from Python methods, that's why I need
to ask.)

If you are talking about pure Python, sure, you can add
class members (data or method) at any time.

-----------------------------
File A.py:

class Chicken:
    def __init__(self, size):
        self.size = size
--------------------------------
File B.py:

import A

def getSize(self):
    return self.size

A.Chicken.getSize = getSize

b = A.Chicken(123)
print b.getSize() # prints 123
--------------------------------

If you are using Zope, you must store your
classes where they can be accessed by
Python. Usually /lib/python/Shared/Local
is a good place, make sure to add the
__init__.py file inside the folder. You
then refer to the class as Shared.Local.Chicken.

What a coincidence.
 I have exactly the same problem. One site with GUF and a CatalogAware
ZClass which silently stops after some time. No errors.

The problem with GUF and DEBUG mode relates to lost filedescriptors.
Someone posted an explanation (maybe a patch too). You might be able to
locate it by doing a search on the list.

Please let me know if you find something out.

I agree. The guides need to be complete, error free, and chock full of
examples.

Hmm. I wasn't aware of the old style syntax, that should definitely be
updated. I also agree that we need to review guides and update examples
to use the latest and simplest techniques. This is especially true for
DTML.

I agree. We do have categories for How-Tos but they are not currently
sorted on Zope.org by category. Probably the categories could be
improved, too.

Again I agree. How-Tos should also provide some feedback system to allow
readers to comment on How-To and point out problems.

Thanks for your excellent ideas!

I'm a little pzzled about :

"objects don't re-import back into the correct place"

I haven't had any trouble exporting / Importing enitre branches. Of course,
I delete the branch to be overwritten first, or at least move, or rename
it. Is that how you're doing this?

XML export may come into play here, since the XML version is parsable. I'm
not aware of any existing Zope tool for dunning a comparison process.

One point that I think is still evolving is a clear set of guidelines
regarding what data is held in Zope, and what should be in other formats,
such as Gadfly. As long as we diligently keep DTML doing templating, and
avoid mixing tabular data and static content in with ZODB objects, it
should be fairly straightforward to do Zope Exports of the Zope Framework,
and file copies, or native exports of data in other "backends".

Mailman has no "global" username/password directory -- every email
address in every list has a password associated with it, that's all.
Known design flaw, and Barry Warsaw (the Mailman maintainer) has
threatened to fix it.

I think this *might* fix the problem you guys are having.  Although we
aren't using GUF or CatalogAware objects, we discovered this on a system
that was under pretty heavy load.

Hello,

I search for a way to implement an URL-Traverse like the SQL-Product. I
need some key/value-pairs for a method and won't use an URL-get like
.../my_method?key=value. Instead a .../my_method/key/value or

Has someone a small code-snipet or something like that which explains the

Hello WorldPilot Users,

There's a new WorldPilot 1.0.3 maintenance release available,
that addresses some of the interoperability issues.
Check out
http://www.worldpilot.org
or
ftp://demo.worldpilot.com/pub/worldpilot/worldpilot-release-1.0.3.tar 


Calendar Problems:
For everybody who had Timezone troubles with the WorldPilot
Calendar, this release should hopefully work for you now.

Please send us your positive or negative feedback to
mailto:feedback@worldpilot.org
so that we know if it now works around the globe :-)


UW IMAP users:
And for all the (UW-) IMAP users there is now a IMAPHACK.py 
file located in the WorldPilot Product directory. Here you
can set the Base IMAP directory (e.g. Mail or INBOX) and
you can choose to only list subscribed folders (but you'll currently
need to subscribe them with a seperate client).

Thanks for all the tips and suggestions! I hope WorldPilot will 
soon operate with most of the remaining other IMAP servers, too.
We're still working on some of those other tracebacks that got
sent in.

Cheers,
Ryan

That's OK. Please do the experiment yourself, it
only takes 3 minutes or less to verify it. You
don't need to trust my words. Trust the result
you see with your own eyes. :)

A good many people in the list have said this
repeatedly: try it first, before posting. I think
it's a little bit too much to ask everyone to
do that every time, but this is a responsible
mailing list and not some flame-loaded newsgroup.
So, when it takes only a few minutes to confirm
something simple, why not try it first?

regards,

Hung Jung

Message-ID: <20000309142919.D183689@isc.upenn.edu>

hi: I'm trying to use the BasicAuth example in the "XML-RPC How To"

http://www.zope.org/Members/Amos/XML-RPC


I keep getting the Zope error when creaing the External Method:

Zope has encountered an error while publishing this resource. 

            Error Type: SyntaxError
            Error Value: invalid syntax

--------

I've just cut and pasted this from the webpage, only removed extra padding spaces, and spliced the one big
line back together:
 h.putheader("AUTHORIZATION", "Basic %s" % string.replace(encodestring("%s:%s" % (self.username,
self.password)),"\012", ""))



The code defines a class and a def:


---------------
class BasicAuthTransport(xmlrpclib.Transport):
    def __init__(self, username=xxxx, password=xxxx):
        self.username=username
        self.password=password

    def request(self, host, handler, request_body):
        # issue XML-RPC request

----------------
In the Add External method page, where you enter in the Function name I've tried:

request
BasicAuthTransport
BasicAuthTransport.request
request.BasicAuthTransport

Which is the right one? it want's the Function 'request', right?

So, the syntax error must be something in the script.

Any help would be appreciated.

You *can* actually get Python to crash if you're intentionally mean to
it.  All the ways I know of involve tricking it into blowing the C
stack, like:

	class C:
	    pass

	C.__init__ = C; C()

Not that you could expect that construct to do anything useful anyway;
you wouldn't ever see code like that in an application.

You have to go out of your way doing really bizarre stuff get it to crash.
It's very stable otherwise.  :-)

First of all, what you want can be done, but it is not that easy.  There
are a couple problems with your design goal, some Zope's, some yours. 
Luckily, the alternative is *very* easy ('very' being a relative term
here, basicly it means you don't have to re-engineer Zope).

You probably know this, but when Zope is tooling down through objects is
traverses them according to various rules.  First, it does something
special (we'll get to that), then it tries to find the next object in
line by just seeing if the next object is a subobject of the current
(getattr).  If that fails it tries to get the next objects as a sub-item
of the current (getitem).  If that fails, then it gives you a 404
telling you it couldn't find the next element in the URL you provided
(you being the client).

The special thing it does is it calls __bobo_traverse__.  This is a
special method.  So you override the root level folder's
__bobo_traverse__ to see if your 'virtual folder' is a user and then
proceed from there.  This is the problem: 1) You can't override the root
level folder, because it's not a folder, really, it's the entire Zope
application and 2) we override it allready so we beat you to it.

Further, although simple, I think you will come to hate having all of
your users in your root folder namespace.  Generally, you want to keep
this namespace as unclutered as possible for many reasons.  One good
reason is that everything in the root folder is acquireable by
everything else, so it's 'prime real estate' in Zope.  Another is what
if one of your users wants to be named index_html?  Or rss?  Your
__bobo_traverse__ method will either have to know all the special names
you want priority on and do the users second, or whatever.  Complex. 
Prone to error.

What you really want is this:

mysite.com/Users/Fred/rss

So you need a special object, in this case instanciated with the id
'Users', that takes the next argument in line as a key into a database,
and doesn't break acquisition paths along the way and lets you do this
fancy URL manipulation.  This special object can have a much simpler
__bobo_traverse__ method, because it's not also trying to deal with
other objects in the same namespace, the 'Users' namespace is dedicated
solely to serving these virtual path elements.  This special object
should also be very generic, not database specific, and should be
programmable directly with various SQL code to execute the query you
want.

This special object allready exists and does everthing you want to do,
it's called a ZSQL Method.  ZSQL Methods can accept arguments in the
URL, and maintain acquisition so you can apply results to 'higher'
objects.  In fact, you can even chain ZSQL methods together to do
multiple database look ups.  Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.

Nifty eh?

Exactly, absolute_url tools up through the various aq_inner wrappers to

Hi Andy,

In my MySQLdb directory, the Setup.in file contains the following:

_mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt

Note that this does NOT point to the location of the Python.h file, as you
suggested it should (below)

I've just finished recompiling and installing Python, Python-devel, MySQL,
MySQL-devel; after each step, I tried to run the build.py script and each
time I get the following error:

 Traceback (innermost last):
    File "build.py", line 14, in ?
      import MySQLdb
    File "MySQLdb.py", line 19, in ?
      from _mysql inport *
  ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

I even tried installing just MySQLDA and that failed, too.

<EXTREME FRUSTRATION>All I want is to be able to connect to a MySQL DB from
Zope.</EXTREME FRUSTRATION>

Any assistance is greatly appreciated!

Eric.

<guess>

You must still use medusa (ZServer, in this case) even if you want to
use PCGI (which is what Zap uses).  ZServer listens to many protocols,
like HTTP, FTP, and PCGI.  If you don't use medusa, PCGI will try to
fire up Zope the OLD way, and it will probably work but it's not the
right way.  The problem is, now your process environment has the wrong
LD_LIBRARY_PATH (and a whole slew of other problems related to running
Zope the old way, like no concurrency) and cannot find your Oracle
dynamic libraries.

Run ZServer first.  Then Zap.  Then it should work.

Yes, the Catalog can be used programatically from DTML and Python.  You
will have to implement your own parser (look at the standard htmllib in
python) that feeds the parsed attributes into the Catalog.

Does it do it out of the box?  No.

I'm sure this is simpler than I'm making it out to be, but here goes...

I'm looking at using SquishDot as a 'home page' for our Intranet, but can't
seem to make its index_html show up as the default document.  What I'd like
is for a user to be able to point his or her browser at
"http://www.mysite.com" and get SquishDot, outisde of setting up a redirect.
What's the easiest way to do this?

I looked at this once and my mind got lost in a sea of table tags.  If
you pin it down conclusivly as a bug, we'll fix it.  But it never
happens on Exploder, and I haven't seen it on Mozilla yet, so I'm

Yeah, and blue people are dumber than green people and orange people are

The perfect counter argument is.  "Prove it."  If this person asks *you*
to prove it, show them the Lawrence Livermore National Labs, the
mems-exchange (all multi-million $+ scientific establishments), Jon
Udell articles, etc etc.  There is a mountain of evidence on your side

Message-ID: <NDBBKGBPJMFODAAFNMKEOEANCAAA.mduvall_22030@yahoo.com>

I think my Zope is working with IIS, but some of the icons in the Management
screen can't be found.

For example, the Control Panel icon is fine:
http://localhost/scripts/zope.pcgi/p_/ControlPanel_icon is indeed there.
This looks like an object reference, right?

The Folder Icon:
http://localhost/scripts/zope.pcgi/misc_/OFSP/Folder_icon.gif , however, is
not. The same is true for the User Folder and DTML Method gifs (and a few
others). In the Zope install, the gifs are in the
root\lib\python\Products\OFSP\images folder.

I'd welcome any suggestions. It's a minor problem, but it's a bit of an
eyesore. Thank you!

Regards,
Mitch Duvall
mduvall@webversant.com

P.S. There was a thread about Zope / IIS last month. I was in a similar
situation in which all I could see when I got to step 6 in Brian Hooper's
how-to was the "Welcome to Zope" page. The change that got me into the
Management screen and logged on was to use the default 401.5 error message
for IIS' "Default Web Site". My thanks to all who've helped out.

Not without javascript, clicking on a lick causes a GET.  Clicking on a
form button causes a POST.  I could be wrong, but I'm pretty certain
that's the convention.

Subject: [Zope] ZClass, Base Classes and logic (QUEST)
Message-ID: <00030915401200.06239@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

Most of the time when someone complains about DTML syntax or the learning curve
and so on, the answer is we should code our logic in python if we know this
language. That's what I am trying to do because I love Python.

However, many times I don't know how to import my logic in Zope. 

example:

I wrote a very simple module MyTest.py:
##################################
class SuperClass:
	def __init__(self):
		self.a='This is a in SuperClass'

class MyClass(SuperClass):
	def __init__(self):
		SuperClass.__init__(self)
		self.b='This is b in Myclass'
##################################
In the python interpreter I do the following things:
>>>import MyTest
>>>import MyTest.MyClass
>>>t=MyTest.MyClass.MyClass()
>>>t.a
'This is a in SuperClass'
>>>t.b
'This is b in Myclass'

That's what I expected. Now I intall the package in zope.  I make a ZClass which
only Base class in MyClass. Its metatype is MyClassClass, so it appears on the
popup menu near the Add button.

But when I try to add an instance I get the following message:

Error Type: TypeError
          Error Value: unbound method must be called with class instance 1st
          argument

I guess that the problem is the line
	SuperClass.__init__(self)

==>however I don't understand why it works fine with the python interpreter and
why not in Zope.

Others behaviors of Zope:
suppose i add the following line in the MyClass __init__ function:
self.d='I am d'

No problem when I run it with the interpreter:
	>>>t.d
	'I am d'

In zope:
	<dtml-var "MyClassInstance.d"> 
renders:
	Error Type: AttributeError
          	Error Value: d

I get the right value of d only with the new instances of MyClass. On the other
hand if MyClass has a property sheet, all the instances are updated if change
the property sheet.

==>So again, why these differences in the behavior of ZClass instances depending
of which part we modify (the python Base Class or the Zope ZClass)?

I really love Zope but I prefer code in python. However I hit often the wall
when I try to put the pieces together. I think that speaking about
documentation : clear API docs would be, for me the most important.
What behavior could I expect from the differents parts of Zope. 

Example of docs I find useful with other 'languages':
Python Library Reference
Java API documentation

What's the traceback embedded in the HTML source of the error page?

It will point you directly to where the syntax error is.

Nope -- that doesn't do it.  It does raise a lot more questions,
though.  :-(

Recap: I'm working in a near-fresh Zope 2.1.4 installation.
Everything's in the root folder.  Two objects of interest:

  my_dtml_meth -
    a DTML method that shows the document title, ID, etc.  (because I'm
    curious); the title for this object is "Test DTML Method"

  my_xm -
    an external method that does nothing except attempt to set the
    document title and call my_dtml_meth; the title for this object is
    "External Method: Call DTML Method"

The code has changed a bit since my last post, so here we go again.
Here's my_dtml_meth (the DTML Method):

  <dtml-var standard_html_header>
  id:             <b><dtml-var id></b><br>
  title:          <b><dtml-var title></b><br>
  document_title: <b><dtml-var document_title></b><br>
  document_id:    <b><dtml-var document_id></b><br>
  title_or_id:    <b><dtml-var title_or_id></b><br>
  title_and_id:   <b><dtml-var title_and_id></b><br>
  <dtml-var standard_html_footer>

And here's my_xm (the external method that calls my_dtml_meth):

  def my_xm (self, REQUEST=None, RESPONSE=None):
      RESPONSE.setHeader ('Title', "Title from External Method (try 1)")
      REQUEST.set ('title', "Title from External Method (try 2)")
      return self.my_dtml_meth (self, REQUEST, RESPONSE)

Note that I'm trying two attempts to set the title; my original guess
based on reading the HTTPResponse code, and Michel's suggestion.

Here's what happens when I call these things.  First, my_dtml_meth, as
rendered in Netscape:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Ie. it's possible to get the object's title using "document_title" --
but the standard_html_header uses "title", so my browser's window
advertises this document as "Zope".  Ugh.  Guess I could fix
standard_html_header, but why does it work this way?

Now I call my_xm, hoping against hope that it will override the title of
my_dtml_meth; here's what I get:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Hmmm... identical.  Ie. neither attempt to set the title in my_xm had
any affect whatsoever.  In fact, I just used a command-line HTTP client
to diff the headers and body, and they compare byte-for-byte.

So: no dice.  Better ideas, anyone?

(I think I've learned enough to solve my problem, though: use
document_title rather than title in standard_html_header, and make sure
the DTML method in question has a meaningful title.  But I'm still
curious why things work the way they do.)

Ha, ha!  Silly me...

Internally, my server is known as 'www.waco.ct' and I set up SiteAccess so
that every request containing 'waco' and 'ct' is redirected to the SquishDot
folder.  Of course, this means that I instantly can't get back to the root
folder for any reason.  To fix it, I shut down Zope, removed the SiteAccess
product manually, restarted, and got rid of the offending code.

I offer this as a warning to others interested in SiteAccess--the product
works great, but think a little before you set things up, lest you fall into
the same trap I did.

Thanks. That was the problem. I persevered in my mistake because I saw
'Data.fs' in my zope folder (probably created by my own mistake).

I try to understand the ZODB because i want to process some data in my ZODB
with python. Do you it is the right way to do it?

My main achievement with Zope is part of the MEMS Exchange mentioned by
Michel:

   http://www.mems-exchange.org/z/process/builder/

This is a tool for people to specify the process sequence to fabricate a
MEMS device (= micro-electro-mechanical system, aka micromachine or
microsystem).  They're typically fabricated using the same techniques as
IC fab, but in much more varied ways -- hence the need for people to
specify custom fabrication sequences.  For non-specialists, most of this
tool is meaningless, but it's an interesting demo of how much user
interface you can get away with on the web using something like Zope.

For the record, before we started playing with Zope, I was convinced
that complex user interfaces on the web were all-but-impossible.  Thanks
to Zope, I now believe that complex user interfaces on the web are
merely very difficult.  

We have found no bugs in Python developing this system; we certainly
have our share of gripes with Zope, but I think we've only seen two bugs
that really affected the reliability of our web site.  The first bug was
when Zope 2.1 came out, and we made the mistake of going straight from a
single-threaded, PCGI, Zope 2.0 installation to multi-threaded, FastCGI,
Zope 2.1; things got really flaky.  I think we're now running
single-threaded, PCGI, Zope 2.1.4 and things are peachy.  We really need
to step gingerly back into multi-threaded/FastCGI territory to see how
it behaves.  The other bug was a nasty ref-counting problem deep in the
bowels of mxODBC, so can't really be blamed on Zope.

I've named the python script ba.py.


Is using 'request' proper for the 'Function name?'

If it's the same error we were seeing, then it isn't that Zope crashes,
it hangs, becomes non-responsive.  It's not spinning, it's just sitting
there not answering.  The reason why (in our case) is because of an
uncaptured exception in the medusa code.  Whenever medusa encounters an
uncaptured exception in a thread, it closes it down.  Well, it was
encountering an uncaptured exception in the main listening thread, so it
shut it down... now Zope isn't listening anymore... so it just sits
there.

If you want debug output without using debug mode, add this code to your
start script (reverse the slashes for Win32, of course):

STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE

Debug information will get stored in event.log.

Ok, my syntax error was that I was replacing the username and password with strings and not putting them in

That's fixed.

But I'm still having an error now.

True enough, though I'd have liked to see more, and I'd have liked to
contribute more, too, which is to say, I'd like to contribute at *all*
-- no time for that at the moment, however. Ironically, I'm too busy
using it to improve it.

I find it ironic that JPython is even *slower* than CPython. Curious --
is anybody using it for anything worthwhile?

I'm not disputing the success of these languages. Perl, Python, PHP,
Pike -- they're all quite successful at what they aim to be (*). But
people tend to use languages rather than contributing to their
development. You can't just evolve a language indiscriminantly, which is
why we have Guido and Larry, the benevolent dictators. You can't just
go, "oh, and I added iterated loops today". Every damn little feature
requires at least some kind of ratification process. Languages are much
more susceptible to breaking.

(*) Except possibly Pike. I'm ashamed to say it, but I find myself oddly
attracted to this language, if mostly because of its speed and
interesting resemblance to C. Pike is a good example of "how to make a
powerful language/interpreter system that's also very fast". Pike has
had a type system from the outset, which is a definite edge over Python.

Where?

The type system SIG has a funny intro: "Recently, the types SIG has come
under attack for inactivity, and in response Paul Prescod has offered to
guide the SIG towards accomplishing a single specific goal: to develop
an optional static typing system for Python. The December 1999 archives
of the SIG show the discussion that lead to this decision."

Reading this stuff now. It's interesting. I hope they get it right.
Maybe I'll chip in.

What's interesting about Dylan is that, because it relies on static
information such as type hints and class/method relationships to be
efficient, the developers of Functional Developer (formely Harlequin
Dylan) are facing a design problem related to how they compile programs.
They've actually put all of the various libraries into shared DLLs.
Unfortunately, this means they lose the benefits of the optimizations
that can be made through the use of static compiler information. When
you load up the [latest beta of the] Developer IDE and compile a
program, it consumes a whopping 45MB of RAM. And it's damn slow. The
absence of such optimizations is one reason for this hogging tendency.
So they're planning on providing a "whole program delivery" option
whereby all libraries would be statically linked.

I have several apps where I would rather use Python, but where speed is
so significant that I would either end up writing a lot of the code in
C++ for speed (which is painful due to the lack of integration between
the two languages -- Python classes can't inherit from stuff in the C++
extension, for example).

I also have a database-centric Zope app that causing me headache. The
ZODB is *way* too immature to replace a database right now -- fine for
the kind of stuff that runs on zope.org, not for us. ream

Pardon me for sending off another email in mid-stride. Damn cat :-)

Let me finish the last sentence first: I also have a database-centric
Zope app that causing me headache. The ZODB is *way* too immature to
replace a database right now -- fine for the kind of stuff that runs on
zope.org, not for us. We're actually looking at alternative app servers
and solutions (such as hardwired C++ CGI code) right now. It's a shame,
and I'm fighting it, but we might end up with something like Dynamo.

I don't necessarily say they're _my_ problems, but some people think
they are, and that counts. I don't miss "switch" myself, although I do
miss a kind of enumerated type.

I remember sitting down with Python for the first time create a simple
CGI type thing, and found that I could just do

  def DoSomething(): ...
  def DoSomethingElse(): ...

  DoSomething(eval('Do' + Args['cmd']))

and then call up the CGI using a query string such as
/cgi-bin/foo.py?cmd=Something. Wonderful, and better than any kind of
RTTI.

The list comprehension syntax is cute, but not, I think, so clever.
Perhaps it'll prove to be a nice feature, even a successful one, but
personally I doubt, even with the knowledge in the back of my head of
how this stuff works, that I would instinctively grasp for a
list-comprehension expression as naturally as I grab for, say, a "while"
loop. My head is just not wired that way, and I think the syntax looks
positively alien for Python -- it's not "pythonic".
 
> I don't think you'll see protected members any time soon.

I think Zope's source code is one huge, glowing argument in favour of
having protected members.

I don't particularly take to the idea of a having
mutability/immulatibility property burned into the type itself.

Tuples are immutable, dicts and lists are mutable. Why? Because Guido
says so. Jon Udell, I think it was, has argued that tuples are currently
a redundant element in the language. Why have two kinds of lists? It
just confuses people.

A syntax for declaring the mutability of types would be helpful in
clearing out this mess. For example, you should be able to declare a
dict to be immutable when passed to a certain function call -- ie.,
forcing a copy. Python has no "out" parameter, only "in" parameters that
are mutable depending on the type of the object passed. The syntax I'm
alluding to would effectively give you both "out" and "const"
parameters.

I haven't thought it through. I just think it was potential. Why
shouldn't the translated function refer to other objects? The function
would essentially just constitute native calls to the Py* APIs -- in
effect, a translated function would summarize the runtime calls made by
the interpreter during normal execution. Therefore, non-translated
Python code could just as easily refer to translated code (within a
"translated module", which would be a special object), because the
translator module would construct the necessary proxy object to forward
external calls to the inner code. Or something. ;-)

I'll let you know. ;-)

Thanks Mike,

You are right, root/Users/<usernames> makes more sense than
root/<usernames>.

I looked at what you said, went away and read ZSQL Methods user guide
(again).

Now I'm back.....

>>
 Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.
<<

So my Zope folder layout looks like this :

root
   index_html (default)
   Users (SQL method)
   Flavor (SQL method)

I assume I would also need a DTML Document called "rss" because the SQL
methods can't actually deliver any content to the client browser?

So, if you would be so kind, lead me through how Zope works on this call :

mysite.com/Users/Fred/Flavor/Cherry/rss

Zope starts to traverse the call from left-to-right?

finds "Users", its a SQL method which takes an argument, aha! the argument
is "Fred",

[Does Zope now run the Users SQL with that argument?]

ok, what's left : "Flavor", okay, I have a "Flavor" SQL method here and that
takes an argument too, "Cherry" is that argument.

Finally, Zope finds "rss", if this is a DTMLDocument or something "servable"
it runs it and returns it to the client?

If "rss" wasn't there it grabs the index_html page and serves that?

=======

Thanks for your help.

Like many others I suspect, I see Zope through a cloud. Sometimes I see the
outlines of it and it glimmers! But I just can't grasp a picture of the
whole.

Ah yes, I didn't realize it was in an external method.  External methods
mask the exact error information.

Just import ba.py into a python interpreter *without* Zope and it will
tell you where the error is.

I have a page that sometimes gets displayed in a frame

display differently (with a header) when its  not
in a frame.  Is there a way I can do this?

I don't suppose the name of the target frame
gets passed to the browser does it?

Presumably the only way to do this would be
to do it in client-side code and fecth the header
if appropriate and filter it to make it what is
needed.  Or is it?

Calling a method with () is a python convention.  HTTP has no convention
of calling anything, we just use the convention that the query string
(everthing after the ? in a URL) is a list of name=value pairs seperated
by &.  This is per the CGI specification.

I'm getting a weird invalid character error on my ZSQL Method using
ZOracle... If anyone could help, I would appreciate it:

I have a method with the following params:

    id username password firstname lastname title deskphone cellphone
pagerphone emailaddr soffice_id sprdarea_id

And the following query text:

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values
      (<dtml-var id>,
       '<dtml-var username>',
       '<dtml-var password>',
       '<dtml-var firstname>',
       '<dtml-var lastname>',
       '<dtml-var title>',
       '<dtml-var deskphone>',

       '<dtml-var emailaddr>',
       <dtml-var soffice_id>,
       <dtml-var sprdarea_id>);

When I test it with example feild values, it renders the following
error:

    Error, oci.error: (911, 'ORA-00911: invalid character\012')

With this SQL Used (which if you try in SQL*Plus, is perfectly valid):

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values

Any words of wisdom?

For the sake of this discussion, yes.

They return query results, which are a sequence of record objects.

Yes.

If you tell it to, check out the 'Advanced' tab on ZSQL Methods. 
(First, don't forget to specify one argument to the method or else you
won't see what I'm talking about).
 
> ok, what's left : "Flavor", okay, I have a "Flavor" SQL method here and that

First it finds Flavor, then it traversed into Flavor, then Flavor find
the next element as its argument (once again, if you tell it to).  So
essentially the answer is yes.

Yes.

If rss wasn't there and it was in your URL then you would get a 404
NotFoundError.  If 'Cherry' is your last argument then yes, it would
acquire the first 'index_html' object that it found, which in this case
is the one in the root folder.

Greetings,


In my experience, to count the size of an array in ZOPE does not require an
external method, simply "_.len(sqlQuery())".  I use this myself in a few places.

I won't try to guess your reasons for not getting sql to count, but surely it
would be by far the simplest way?

Thank you Michel,

After trying your suggestion I came upon this problem:

A white screen with "No Items were specified!" at the address:

   ../BOStorage/manage_delObjects?id=20000428164227

(BOStorage is where the objects are stored and I verified the id#
20000428164227)

Thanks.

Can they do that? How? Something funny in the license agreement?

Subject: [Zope] Use only part of a list sequence? or External Method to Insert ZSQL?
Message-ID: <019301bf8a24$162d8180$5e577e86@jmu.edu>

To all Zopists,

<background>
I have a form that has several dynamically generated options from a MySQL
database.  I have each option using a hard-coded array like
name="mylist[0]", name="mylist[1]", etc..., and keep the value blank unless
selection is made.  Everything is working fine.  In the next page, I will
insert the Authenticated_user as the userid, and another field into a table
in the MySQL database.  When I get to the next page, I have:
...
<dtml-in mylist>
    <dtml-if "_['sequence-item'] != ''">
      <dtml-if "countuser(`AUTHENTICATED_USER`) < 6">  ##countuser counts
user in table
                 will be inserted into tabel here...
      </dtml-if>
    </dtml-if>
</dtml-in>
...
People are only allowed to have 5 entries in the table.
</background>

Here are my questions:
1.  Should I use an External Method that accesses a ZSQL Method to insert
the fields into the table?
(please give me an example of this, it sounds interesting...)

2.  Is there a way to only use the first 5 listings of the sequence?  Maybe
save into another list, then go directly to a ZSQL method insert?

3.  Should I just quit and go home?
:o)

Any help would be greatly appreciated.

   No, it takes a string. Try:

<dtml-call "RESPONSE.redirect('/target?myvariable=xyz')">

I would like to redirect a user based upon a variable.

<dtml-call "RESPONSE.redirect(/target?myvariable=xyz)">

raises a syntax error.  Does the redirect command only take literals?

redirect takes string.  The correct syntax would be:

<dtml-call "RESPONSE.redirect('/target?myvariable=%s' % xyz)">

Remember, once inside quotes ("") you're writing Python code.

Thanks again Mike.

So my final (I think, for now) question is this :

The whole point of Zope is to get a result back so the URL :

mysite.com/Users/Fred/Flavor/Cherry/rss

is (the way we have discussed it) really a way of saying : "I want an "rss"
document containing information related to User=Fred, Flavor=Cherry.

So in order to get my content out I just have to do some things with
<dtml-with Users> and <dtml-with Flavor> in my "rss" document? (because
these SQLMethods will already have been set up & run as part of the URL
traversal and are ready to give me data?)

I appreciate your patience,

- Ian Sparks.

That would be the last semi-colon ";". Remove it and use in the ZSQL method.
Additionally, instead of <dtml-var  ...>, you might want to consider using
<dtml-sqlvar >, which will assist you in properly SQLising the data.

Subject: [Zope] No resposne to valid HTTP requests.
Message-ID: <00031011262501.26896@localhost.localdomain>

Greetings,


So, I got into work this morning, ready for another day of zoping, only to find
my server not quite responding properly.  When i went to the manage screen, the
tree frame didn't fill, but the right-hand frame was fine.

Hmm, thought I.  Oh well... i can work without it.  So, I clicked on the folder
for todays work and..... 

nothing....


no response at all, not ever a timeout!

Talk to the network admin, we both kick about... and it seems that the ZOPE
server will respond correctly to invalid GET requests, but just freeze on valid
requests.

Further testing shows that it's ONLY when i try to use the management screens. 
The only change in my system recently has been upgrading from NS4.7 to NS4.72.

It's RedHat 6.1, and Zope 2.1.4.

Any idea?

Yeah, that would be very helpful.

As a Zope Newbie, who's developed lots of database stuff in PHP and Perl, I 
am unclear on whether I'm "supposed to" try to make everything an object in 
ZODB.

Say I'm making a repository of documents, like articles or e-mail messages, 
and I expect to end up with 100s of thousands of those, should I 
confidently work on making them all Zope objects, or should I stick with 
mySQL records and/or files in the file system, like I normally would?

As a follow up... i checked another site of mine, and it is now showing

The whole server seems to have locked up.

You don't even have to work that hard, consider what happens:

Let's say that your Users method queries a table that contains two
columns, name and title.  Primary key is 'name'.

Your second method queries a table that contains two columns, flavor and
size.  Primary key is 'flavor'.

Users method is called with 'Fred' as argument, this returns a single
record object.

ZPublisher then tries to find 'Flavor' on that record object, it doesn't
have such an attribute, but it CAN acquire it, so it does.  It discovers
that it is a SQL method and calls that method, *in the context of the
first record object* (keep that in mind...).

The second method is called with 'Cherry' as a argument.  It returns a
single record object.  Now, ZPublisher tries to find 'rss' in that
record object and fails, but it DOES acquire it, *in the context of the
second record object which was found in the context of the first*.

Now you are in the rss method, but you are also in the context of the
second and first result objects, in that order.  So in your method, just
say:

Hi my name is <dtml-var name>.     I'm acquired from the first result
object.
My title is <dtml-var title>.      I'm acquired from the first result
object.
The flavor was <dtml-var flavor>.  I'm acquired from the second result
object.
The size was <dtml-var size>.      I'm acquired from the second result
object.

Note that if a subsequent record object has a column name identical to
that of a preceding record object, the subsequent one is acquired
first.  This means that subsequent results can 'refine' previous ones.

Note that this concept of accessing one object in the context of another
is what is called Acquisition and all Zope objects support it, not just
ZSQL Methods.

--------------------------------------------------

(1) It should work. I have tested it. Nothing
    special is required for the __init__.py file.

(2) Make sure that you have an __init__.py file
    inside your lib/python/Shared/Local folder.
    This file can be empty. Or you can provide
    some __doc__ and __version__ string like
    Digicool people do. But it really can be
    an empty file.

(3) Inside that folder, create a file Chicken.py,
    which contains the following three lines:

    class Chicken:
        def __init__(self, size):
           self.size = size

(4) This python file will not compile automatically.
    It will only be compiled when it is imported
    by some other Zope modules.

(5) To test what you want: create an external method.
    In the folder Extensions inside your Zope root
    (if you don't have an Extensions folder, you
    have to create one first), create a file Test.py
    containing the following lines:

    import Shared.Local.Chicken

    def getSize(self):
        return self.size

    def test(self):
        Shared.Local.Chicken.Chicken.getSize = getSize
        a = Shared.Local.Chicken.Chicken(123)
        return a.getSize()

(6) Go to Zope management screen. Restart Zope.
    (Or shut it down and restart it manually.)

(7) Create an external method with 'Id' = test,
    'Function name' = test, Python module file = Test
    and click on the 'Edit' button, then click on the
    'OK' button. If you don't know what an external
    method is, you've got bigger problems than I
    thought. :)

(8) Hit the 'Try It' tab.

Done! now you can use the external method inside
your other DTML documents/methods. For instance,
you can have a mytest_dtml method with the following
lines:

<dtml-var standard_html_header>
<dtml-var "test()">
<dtml-var standard_html_footer>

and it will print the number 123 when you view it.

I shouldn't have treated you like a 3-year old.
But I guess making instructions as clearly as
possible eliminates unnecessary confusions. :)
We've all been newbies once.

This really isn't enough information for us to do anything except
console you.  Can you do some more investigation?  Try shutting down
your Zope and going to the lib/python directory and then doing this:

bash$ python
Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [GCC 2.7.2.3] on linux2
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import ZPublisher, Zope
>>> ZPublisher.Zope('')

Does that return your top level ('yoursite.org/') content?

Are you using some non-standard modules like SiteAccess?

Yes, I am using SiteAccess.  However, this site has been working fine for some
weeks now.  The site works until you go to the management screens.

Also, an older site of mine (running on Zope 2.1.2) has also shown the same
problem, which started last night.

Two seperate sites showing the same problems at the same time?  Coincidence? 
Not likely.

No you are doing it the right way and it should work fine.

Is there an error and a traceback?

Ha! This must be the most innocent message in a long time. :)

BookS on Zope? Good titleS? Get THEM? Oh boy, oh boy.

There is ZERO book on Zope. But DC people neither confirms
nor denies book deals, this is what I last heard.

All what I need to know in Zope I learned it from the
net, just like everyone else. :) The myriads of loose docs
plus the mailing list does the job. Poorly, but it does
the job.

A good Python book is a must, though, when you want
to get into more advanced features of Zope. O'Reilly's
"Learning Python" by Mark Lutz and David Ascher is
a good bet, well... maybe the only bet. :)

No error or traceback.  It takes me to the "manage_test" page and I can put
the number in manually, and it works.  The crazy thing is, I can force-feed
it the manage_test, like:

<a href="/queries/SearchResultPage/manage_test?theid=<dtml-var
the_id>">link</a>

and the test comes up ok. I don't have a clue on this one...

There are no books on Zope yet.  Mike released a plan some time ago about a
book that he was working on w/ O'Reily.  Maybe he'll give us some new info
:)

I suggest "Learning Python" to get more acquainted with python and then
using the mailing lists and stuff on Zope.org for now.

Later, Nick

Mike,

The problem was on my end.  I was referencing the method instead of the
report page.  Ok, I admit, oops on my part.  Sorry for the trouble. Been
here at work to long.....

I think it's time to go home....it can wait 'till 'morrow....

Thanks for helping my step-back and think alittle.

I don't know what it is, but something had to happen, unless there is
some mysterious kill-your-Zope-on-Mar-8 virus going around.  The one
upgrade to Netscape is unlikely.  But *something* had to happen to both
boxes.  They may be related, they may very well be coincidences, but
neither of them manifested themselves by themselves, that is even more
unlikely.

Greetings Thomas and welcome to the Zope list.

One place you may want to start is WorldPilot (http://www.worldpilot.org).
WorldPilot is a will handle some of your needs. Its a web based PIM with
e-mail, scheduling, address book, and to-do list functions.

What type of document administration are you looking to do? I have some
Notes/Domino experience and if that is your reference point I may be able to
help you find answers based on Notes style solutions.

Thanks a lot for this info...  Well, in that case, I have to be content

No nothing. Really weird. I have actually tried on a Zope instance that
was accessed only by one person and still it will silently stop after some
time. Nothing related to heavy load ...


Could be related to GUF as I was getting some exceptions from GUF but they
were uncorrelated in time.

Thanks a lot Nick

I haven't tried out your suggestions yet but I *hope* they point to the
problem. You write nevertheless that in your case Zope hangs, whereas in
my case the process just dies silently and doesn't even trigger the
manager to restart it. I will try my own supervisor on it and see how it
behaves.

I don't think you need to really get out of your way to crash python. For
someone discovering __getattr__ for the first time and wanting to do some
simple delegation ...

class A:
    def __init__(self):
        self.a=[]
    def __getattr__(self,key):
        if hasattr(self.a,key):
            return getattr(self.a,key)
        else:
            return getattr(self,key)

Wrong but not really bizzare IMO

The story so far...


Well, the second site which appeared to be showing the same problems... isn't. 
It is now working fine.  So, I'm left with just the first site, which is
currently the more important site.

I can traverse normally, until i try to enter a management view.  Then, the
frames arrive, and, upon first attempt, /manage will work, except for the left
frame.  After that, no manage screens work at all.

I do have SiteAccess, but even with __no_before_traverse__, the same problem
occurs.  I can go back to regular pages, and all is fine.

Have a better one,

Please do not try to match the start tag and end tag again and again in
zope.

Please come to see the http://zope.org/Members/kentsin

and get the root.zexp for evaluation.

This is a set of method/attributes which will publish the folder's index_htm
document

The methods will generate the doctype, stylesheet, javascript, rdf for the
document.

It can be configure by setting certain attributes.

Hope this will get into the zope mainstream.

Rgs,

Your problem definitely seems to be coming from
SiteAccess. Evan should be able to help you out.

What you may want to do first is to disable
SiteAccess first. Something like:

http://www.whatever.com/__no_before_traverse__/path/to/rule/manage_main'

Then go to the management screen and UNDO that very last thing
that causes SiteAccess to get into infinite loop. If Zope is
not problem, do you have Apache re-write rules somewhere
modifying your URLs?

The first time I used SiteAccess was also my last time.
It was so freaking scary to have a hang-up situation where
you cannot do anything except cry in desperation. :)
Several people have reported problems with SiteAccess.
It's not that I don't think SiteAccess is great: its
concept is great, just that I don't ever want to get
into this kind of scary situation again. :) I am waiting
another few months before I get more reliable version
of SiteAccess or its equivalent in Zope. And no, thanks,
I won't be a guinea pig to reproduce the bug. :)

Subject: [Zope] Zope + Coda = Client Side Zope?
Message-ID: <00030922411300.00635@viking>

Some of the dsicussions in the Client Side Zope thread got me to thinking about
an article I read in Linux Journal sometime ago on the Coda file system. As
luck would have I can't seem to find that issue. Most of the information
contained in that article (now over a year old) can be found in updated form at
http://www.coda.cs.cmu.edu/ . 

For those who've not heard of coda its a distributed filesystem that supports a
variety of the features, including disconnected operation and replication among
multiple servers, that were mentioned in the previous thread. 

I will admit to knowing only the very surface information about coda and throw
this to the list for anyone who has actually used it. Also do any of the DC
folks think that a data store centered around a coda type fs would be doable?
I've been intrigued by coda since I first read the article this may be the
reason to explore further.

Any other thoughts on this?

(I read your post and understand you have this working now)

Just wanted to mention there is another 'shorthand' way:

<a href="/queries/SearchResultPage?theid=&dtml-the_id;">link</a>

A little more compact than the one with <>s.

Server is still up, but I'm wondering if these channels reopen or if
they all close if that's what stops the server?

I can see how this exception is getting left unhandled in the medusa
code, so I'm going to try and catch it and startup the server again.

Greetings...


After trying constructing an entirely NEW zope install, and winding up with not
being able to import the backup of my site, I decided to reboot.

Strangely, everything is working again.

Oh well... at least i've learned some more about the innards of Zope.

Absolutly, but in this case you can just use FileStorage, since coda is
a filesystem.

I attended the Coda session at last year's Linux Expo.  There, the
professor in charge of the project gave a very clear explanation of coda
and how it works.

Useful results with Zope should be immediate, Simply store your Data.fs
file on a filesystem that is replicated by Coda.

There is a more interesting application however, and that is
implementing the actual coda protocols themsleves into a sort of
ReplicatedStorage (I'm not positive if that is the best way to slice the
pie, but it's an idea).  Another idea is to roll a similar or identical
protocol into ZEO, so that not only are Storage Clients and Storage
Server are distributed in a parent/child relationship, but also that
Storage Servers can be distributed in a peer relationship that replicate
each other to provide failover and replication.

Interesting stuff in any case.  I'd really like to hear about someone
who has a success story with Code and Zope using just it's filesystem
capabilities.

Subject: [Zope] WorldPilot Acquisition?
Message-ID: <CC59868A0A76D311B1F50090277B321C1F31BA@VRTMAIL>

I've been mucking around trying to get Acquisition to work with WorldPilot
objects (I want to define methods/documents that can query WorldPilot's
"normal" objects (Events, Address Cards, Notes, Todos, etceteras), and the
collections of the same.  So far no luck (I don't really understand
everything going on under the covers of either Zope _or_ WorldPilot, so I'm
not likely applying pressure at the right points).  I've been adding
Acquisition.Implicit to the hierarchies of just about every object with no
luck so far.

Does anyone have ideas on how to go forward?  Could I alter the "normal"
objects in some way to make them accessible at a higher-level (for example,
if I could get at the objects in a flat collection, I could run my queries
against them, using their types to sort into virtual collections).

I suppose, in a pinch, I could just read the local files and construct a
query against them, but that seems... well, too incredibly hacky.
Incidentally, why does WP use all these custom storage mechanisms?  The
actual objects don't seem too complex, and the interface doesn't _seem_ like
it would require the support.

Ideas appreciated,
Mike

Um, no. Since the code that defines 'layout.table' is also available and
editable, (just like any other object).
So you can not only code the specific header you want into the object, but also
create a parameter which can be used like so:

 <dtml-var object="layout.table">
   <param name="datasource" value="get_above_age">
   <param name="columns" value="Name,Age">
   <param name="table_tagattrs" value=" border=0 bgcolor=green">
 </dtml-var>

I learnt you're doing something similar (from Rik). I have to look at it.

What I'm suggesting is that instead of having to create a product every time
you want a higher level object, we could have a framework so that you could
just create an object that does it. The goal would be to make it easy for
everyone to code their own component objects (or templates, or patterns,
or whatever)

Another thing I would like is that people start looking at 'documents'
differently. Instead of 'my_element_header' and 'my_element_footer', people
think of 'my_element' which takes one or more parameters. (Please don't flame
me, it's Paul who started all this :-)

I guess not. The problem I  have fits the description, but I don't use GUF.
I have the impression though it has to do with busy interactions with a
Gadfly database. Platform: Windows NT, Zope 2.0.1.

Message-ID: <38C8CAC9.C45A5056@nipltd.com>

Just an idea, but if you want to see if it's a bug, or 'non-standard' html
problem in Zope, try copying the 'view source' html of the tree into an html
document and editing it in Dreamweaver.

Dreamweaver seems very good at finding html problems, and you can run tests to
see if any browsers aren't going to like it.

Hope this helps...

Subject: [Zope] trees, hypernews and frames
Message-ID: <38C8C8E0.AB71B295@open.ac.uk>

Sorry, this is involved and takes a lot of words to explain.

I'm building a zope site which also serves HyperNews
discussions.  Apache and Zserver are working well together.

What I have is a tree widget iterating over a folder,
some of whose elements are treated as hyperlinks to hypernews
discussions.  Base articles for discussions are in the
contents of the zope items so .... when  you click
on an element in the tree it follows a link to hypernews
and the hypernews fetches the contents of the "same
item" you just clicked on.  This is a roundabout
way but the only way I know to keep my hypernews headers
and stuff in zope It does all work well but....

My first implementation had a two column table with
the tree on the left and the particular discussion on the
right.  This worked well logically but wasn't too visually
appealing because as you expanded/collapsed tree branches
everything moved around on the page.  So I re-organised
it to use frames - a header frame, then two columns
(tree in one, discussion in the other) and a footer
and this works very well.

My problem is now this - except for the top one
the frames on the page do not include 
what in the former implementation was the header (i.e.
the fancy bit at the top that gives context and doesn't move).
Now its possible and common to access the hypernews discussions
without coming in through the zope home page with the tree
widget.  It is common to do so because when hypernews sends
email it puts a hyperlink to the item in the email which
does just that.  When this hyperlink is followed the page is
fetched from zope but of course the fancy header isn't there.
Since its no longer displayed inside the frameset the
header needs to be displayed as well but isn't.

That's the crunch.  How to get the fancy header served
when its displayed outside the frameset but not served
when its inside.  If it were all in zope then this could
be done by passing a variable value so the page could
know how it was called but hypernews does not pass on
anything like this when it fetches content from other
servers.

Anyone think of a way round this?

Please copy replies to
a.k.heath@open.ac.uk
as I take the digest.

The Guides on http://www.zope.org are available for download and can be printed
out, they feel almost like books if you spiral-bind them ;-)

Seriously, though, they are a bit out of date but certainly a very useful for a
beginner. the order I'd recommend:

Zope Content Managers Guide
Zope DTML Guide (more of a reference really...)
ZSQL Guide (if you want stuff out of a DB)
ZClass Guide (this is probably the worst of the guides and I personally didn't
find it very helpful...)

All available from http://www.zope.org/Documentation/Guides

You can easily turn off ZServer's http server but still leave the other
servers.  Or you can turn them all off except for PCGI.  See the usage
documentation in the z2.py file in the Zope top level folder.

Subject: [Zope] Searching in textfiles
Message-ID: <20000310114307.95496.qmail@hotmail.com>

Hi all!

I'm quite new at this whole Zope thing, so I'm probably overlooking 
something quite trivial.
Here's the deal:
I've uploaded some text files into a folder called "Taglines" there are some 
30 files in all. Now for the problem: How do I search the contents of the 
files?
I made a ZCatalog and I know I have to make an index on "something" but I 
can't find what that something is.
Can this be done? And if so: How?

greetings,
Bart Holthuijsen.

Subject: [Zope] REQUEST vraible methods
Message-ID: <38C8E437.3B1D9AC9@nipltd.com>

Hi,

I'm trying to write a SiteAccess Rule to do some simple virtual hosting helping.
Basically, I'd like to have access from http://www.mydomain.com (which is
virtually hosted...) and from http://zope-host.nipltd.com/mydomain (the actual
Zope host) and have all the management views, absolute_url()'s, etc working
properly.

If you just drop a SiteRoot in /mydomain then everything works fine through
http://www.mydomain.com but http://zope-host.nipltd.com/mydomain/manage just
jumps to http://zope-host.nipltd.com/manage. So I'd like to write my own Access
Rule to do this.

Now, the documentation for SiteAccess mentions a few methods of the REQUEST
object that I can't find documentation for. I was wondering where I could find
complete documentation for the REQUEST object, or how I can find out what its
data and method attributes are?

cheers,

Chris

   You don't need AccessRule for this - just path correct SiteRootBASE and
SiteRootPATH environment variables to SiteRoot. Define it differently on
every server, that's all.

Hmmm,

Not sure I get you, and I'm not sure my explanation was clear... ;-)

I'm only dealing with one server, which hosts several sites.
Each site is in its own directory off Zope's root.
eg: http://zope-host.nipltd.com/mydomain

Each of these sites has its own domain name, which is virtually hosted using
Apache as a front end into Zope. 
eg: www.mydomain.com --> http://zope-host.nipltd.com/mydomain

Now, we typically maintain the sites with:
http://zope-host.nipltd.com/manage
and navigate through the links from there.

However, site owners may maintain the site with, for example:
http://www.mydomain.com/manage.

Also, currently, wherever there's an absolute_url() or the like, such as in the
management screens or in Squishdot sites, links are generated as follows when
accessing through www.mydomain.com:
eg: http://www.mydomain.com/mydomain/manage

If you follow these links, they work through the magic of aquisition but,
through following several such links, you can end up with rediculous URLS.
eg: http://www.mydomain.com/mydomain/mydomain/mydomain/mydomain/manage

I think SiteAccess's Site Root's are designed to sort this out. You drop a Site
Root with a path of / into the /mydomain folder.
Unfortunately, this site root also affects access through
http://zope-host.nipltd.com/manage and so if you try and follow the link to
http://zope-host.nipltd.com/mydomain/manage_workspace you in effect get
redirected to http://zope-host.nipltd.com/manage_workspace 'cos the Site Root
strips out the /mydomain.

Also, if you go to http://zope-host.nipltd.com/mydomain/, all the links are
broken for the same reason.

Which is why I want to use an Access Rule instead and make it a little cleverer.

Which is why I'm trying to find out what methods/variables there are in the
REQUEST object, which doesn't appear to be documented very well ;-)

cheers,

Chris

Actually that's not _completely_ true.  The Quick Python book has a
chapter written by Brian Lloyd and Amos Latteier on what used to be
Bobo.  It's still a useful intro into the idea of object publishing with
Zope.

   Do not pass any SiteRoot* variables in this domain and pass both in
www.mydomain.com.

   SiteRootBASE => http://www.mydomain.com
   SiteRootPATH => /

That should do all tricks you want.

Richard,

The equality check on AUTHENTICATED_USER will always fail because your
comparing an object with a string.

You need soemthiong more like :

<dtml-if expr="AUTHENTICATED_USER.getUserName()=='zope'">

One tiny datapoint.

I set up a small Engineering Change Request system w/ zope and
PostgreSQL 6 months ago.  It has been running flawlessly [1] ever since.
Machine uptimes are in the mid-2 digits (i.e. about every 2 months we
have to rearrange things in the lab).  Note this is a very low load
application.

As for perl/python stability, you could go back and see how often
new releases come out and use that as an argument.

Okay, I think I'm starting to understand more, btu I'm still not quite there yet
;-)

When you say 'pass any siteroot variables' what do you mean?

Do you mean pass them from Apache?
Do you mean set them as properties somewhere?
or something else....

Well there goes this weekend. ;-) I've grabbed the Postscript copies of some of
the coda documentation and I think I'll attempt to set something up this
weekend if I have a chance. My "lab" setup includes a Linux server, a Linux
workstation, and a Windows 95 workstation, so I'll be able to check so measure
of "cross-platform-ness".

The idea of a ReplicatedStorage mechanism is what I was (mis)firing at with the
original question on feasability.  As I have stated before on this list some of
my background is Lotus Domino/Notes and this could bring Zope close to some
functionality of a Notes Client/Domino Server interaction. (I won't bore the
list with details if anybody wants some I'll be glad to do it outside the
bandwidth of the list, unless a lot people want it :-)

It looks fine, so far and i downloaded it.
I'm not sure if i understand the Workgroup-sharing correctly - can
different users participate at the same Address-book or Calendar?
I mean does it support a shared calendar for several people?

If yes, this Product is my way to go and Zope and WorldPilot will get another

I'm not entirely sure here - the client wants something that would be

to use LINUX and Zope. As i can tell, Notes/Domino may be exactly what

   Exactly this. How do you access Zope from Apache? Proxy, FastCGI or
PCGI? They all have different methods to pass vars (and I afraid proxy
doesn't have such way).

   Properties will be used for all domains, that why I said set path
property empty in SiteRoot.

You can set any terms you like in your use license. Whether they are
enforcable in a civil court is a separate question. For example, all
through the '80s Oracle Corp. had a restriction from including Oracle
product in any product comparison, such as benchmarking. 

Sometime in the early '90s Oracle Corp. lifted that restriction. It may
have something to do with the fact that Oracle was finally running fast
enough to look good next to Informix, et. al. 

Microsoft picked up on this mode and had similar restrictions inserted into
SQL Server licenses. I didn't know about that part of Microsoft's license
until I heard Larry Ellison talking on a radio interview, blasting Uncle
Bill for this dispicable practise!

Okay, we use proxy :( . Also, the URLs are rewritten by Apache so that all the
relative links don't go to http://zope-host.nipltd.com/mydomain/*whatever* as
opposed to http://www.mydomain.com/*whatever*

What I was thinking is to write a Site Access rule as follows:

If the host name is zope-host.nipltd.com:
	do nothing
else
	<dtml-call "REQUEST.setURL(path='/')">

Maybe storing zope-host.nipltd.com in a property of the root level folder too.
My only problem is finding out what the host name is.

Will REQUEST.environ.HTTP_HOST be set by the time an Access Rule is called?

Richard,

The equality check on AUTHENTICATED_USER will always fail because your
comparing an object with a string.

You need soemthiong more like :

<dtml-if expr="AUTHENTICATED_USER.getUserName()=='zope'">

Subject: [Zope] how to tell if displayed in a frame
References: <38C82A33.B333748A@open.ac.uk>
Message-ID: <38C9047B.53DAD777@vt.edu>

It can be done in server-side code, if you know when you put the
document in a frame or not.
Something like the following might help:

In the document in question, do some code like:

<dtml-if in_frame>
...display definitely in frame
<dtml-elif not_in_frame>
...display definitely not in frame
<dtml-else>
...default display, which may be the same as one of the above
</dtml-if>
You will probably want to factor out the duplicated content into
subsidiary methods.

Now, if you want the default view, call it as <dtml-var mydoc>

If you want it in its frame view, call it as <dtml-var "mydoc(_.None, _,
in_frame=1)">
You might want to make a dtml method called e.g. myframedoc with the
above code so you can call it as a url.
<frame src="myframedoc" title="blah">

Another way is to call the document in HTTP:get format in the frameset.  
like: <frame src="mydoc?in_frame=1">

Thanks for solving the immediate problem Phil - another UK Zopista - 
there's a few of you out there ! I think I've had help from all of you in 
turn :-)

However I think this reveals a basic problem with the syntax which is 
causing me grief and presumably there are others like me out there.

I would expect an object to behave consistently wherever it was used - so 
if it renders/returns/evaluates to 'zope' inside a dtml-var I would expect 
it equally to render/return/evaluate to 'zope' inside a dtml-if.

If it doesn't then surely we have an inconsistent syntax. How do we know 
how any object is going to behave inside a dtml tag ?

Any comments ?

Why do you want to do this? Have you thought of why it is there?

Create a folder 'Foo' with an index_html method in that Folder, and a 'bar'
method. The index_html document contains a relative link to bar
(href="bar"). Next, go to the URL:

  http://your.server.name/Foo

Note the lack of a trailing space. If you now follow the relative 'bar'
link, you'll neatly end up in http://your.server.name/Foo/bar.

However, had you removed the BASE tag, your browser would have attempted to
load http://your.server.name/bar instead. This is because the relative URL
is offset against the last slash in the URL. The BASE tag however, tells
your browser that the actual URL of the document it is showing, contains an
additional slash.

So, unless you have a really good reason, you don't want to remove that
slash. And if you do, you have to make absolutely sure that the visitor will
never end up on a URL of which the browser needs to be notified is different
from the actual URL.

Richard,

As someone earlier today on the list said, "if it's in quotes it's python"
(or something similar).

Basically Python rules apply when using any expressions in zope dtml-var and
other tags.

Well, that's how I think of it.

Message-ID: <013601bf8aa5$e2733060$0a00000a@smartway>

Hi all !

I try to learn Zope...

I have a very simple ZClass myClass.
This Class has few properties (let's say title:string, description:text).

I would like this class to have 2 methods that can render its instances
simply.

Let's say DTML Methods :
render1
render2

I've made thoose two methods in my Class :
ex :
render1 :
Title : <dtml-var title><BR>
Description : <dtml-var description fmt="structured-text" newline_to_br>

and render2 :

<B>Title</B> : <dtml-var title><BR>
<B>Description</B> : <dtml-var description fmt="structured-text"
newline_to_br>

(the examples are stupid !)

But when I call the methods from the index_html of my content folder like :

<dtml-var "myClass1.render1">
or
<dtml-var "myClass1.render1()">
or
<dtml-call "myClass1.render1(myClass1)">
or
<dtml-call "myClass1.render1(_.None)">

None of theese shows me the infos :(((((
Sometimes, i have AttributeError, sometimes Authorisation PB :(


Please help !

I still think it's an inconsistent syntax.  It should be possible (by
overriding __coerce__, I think?  I haven't had time to look this up yet)
to make the == operator do something different.  AUTHENTICATED_USER is
often used as a string (at least what I've seen of it ...)

Also, "if it's in quotes it's in python", why do I need to do _.str()?  
why does dir() not work?  It seems like some pretty horribly munged sort
of python...

Message-ID: <NDBBLENPLCPAHKODFHNGAEMHCNAA.morton@dennisinter.com>

A number of people have expressed a desire to have XSL support in Zope. The
projects I am working on also seem to be needing the application of XSL, and
whilst we can (and will) use some external XSL processor, it would seem that
a 'cleaner' solution would be to have XSL support directly in Zope.

I originally came to want to use Zope because I needed a tool that allowed
the manipulation of a persistant tree of objects; my prototype was done in
XML, but it needed persistance, an interface, and a programming language,
hence the use of Zope. Even having only XPath support would be an extremely
usefull way for packaging up simple 'queries' on the Zope database.

Ive been looking around at the Python XSL implementations and the
FourThought 4suite is looking pretty damned good, especially considering
their goal of eventual ODMG 2.0 support. Zope desparately needs some
standards compliance, even if only for the buzzwords.

The question on my mind is: how much do other people want XSL in Zope?

Im willing and able to put some $$$ up for a bounty on this. Is anyone else?

I guess Id also like to heard what DC has to say about this; whether they
are willing to have an external group contribute/merge a key technology into
their codebase, and if they have any preferences about who this group might
be.



---------------------------------------------------------------

Heres what Uche Ogbuji of FourThought has to say about Zope
http://www.pythonjournal.com/volume1/issue2/col-intranetpython/

The Zope Dope
Digital Creations, fresh from a capital infusion, has given Pythoneers their
first complete native Web application platform in Zope.  the "Z Object
Publishing Environment".  Zope is similar in scope to Cold Fusion or
SilverStream, but open-source and python-powered.

Zope accumulates many bits and pieces of a successful Intranet site.  It
incorporates a database management system with object extensions (which,
unfortunately, doesn't yet support the Object Database Management Group's
specifications) as well as facilities for developing template Web sites, an
application framework, a CGI mechanism for handling HTTP requests for
objects, an HTTP and FTP server, and a comprehensive application framework
to tie it all together.  Z Templates are developed using a proprietary
XML-based language, the Document Template Markup Language (DTML).  ZTML does
make some departures from the XML community in such areas as style-sheets,
but it is hoped that Digital Creations or other contributors to Zope will
work to close that gap.

Zope is a synthesis of Digital Creations' many earlier products, such as
Bobo, Principia and PCGI.  Bobo has been especially popular among Python/Web
programmers, and Zope looks poised to retain the tradition.  If Zope can
move a bit closer towards object database and XML-processing standards, it
is likely to be quite popular outside the Python community as well.

Subject: [Zope] External Method to view ZSQL Record
Message-ID: <00c901bf8ab6$b38ce6e0$5e577e86@jmu.edu>

To all Zopists,

I would like to use an External Method to access a record field from a ZSQL
method by referencing another field in the record.  If I set the External
Method up such as:

def viewfield(self,reference_field,search_value,field_value):

where:
reference_field = So that I can tell it the field I want to reference
search_value = The value of the reference_field to query
field_value = The value of the returned field, that I was looking for

Do I use a "return" or a "result" or something else?  I still don't have a
handle on python yet, so I'm not sure what to put on the second line of the
method.

Thanks for all the help so far, and thanks for the help on this, in advance.

Message-ID: <NDBBLBELNHAPHBBCOIFDGELDCBAA.ewalstad@energywright.com>

Hello all,

I have tried everything that I can think of (& a lot of what some of you
could think of) to get MySQLdb to compile and install.  I have had no luck.

So, I am now trying to install MySQLDA (a step back) and am still having no
luck.  I'm hoping that the MySQLDA problem is related to the MySQLdb problem
and that one of you will be able to point me in the right direction.

Here's what happens when I try to install MySQLDA:

First, the 'make -f Makefile.pre.in boot' script seems to work fine, but
I'll include the output anyway, just in case.

As far as I know, I don't thing it's possible in Zope. I'm very interesed in a
way to do that, so I thought about a possible solution:
- make an empty class in python, e.g. MySuperClass;
- when creating your ZClass, make MySuperClass one of its Base Class;
- if you want to modify your ZClass Base classes, just add super classes to
MySuperClass and create/modify and __init__ method in it:

class MySuperClass(NewBaseClass01, NewBaseClasse02...):
	def __init__(self, parmeters...):
		NewClass01.__init__(parameters01)
		NewClass02.__init__(parameters01)
		...
It sounded a good idea to me and worked fine in python. However I got:
******************
Error Type: TypeError
Error Value: unbound method must be called with class instance 1st
argument
******************

Not very useful but who knows. Let me know if you figured out a solution.

Hello,

I am trying to display a sequence of numbers with next to each of them the

buffer to add at each cycle the value of the new number. But I can't figure 
out how to create a variable.

Can somebody tell me how to declare such variable?

I've always noticed the same thing, over a period of months. I'd also like
to know what it signifies. Is the list stored in the ZODB, and is this
therefore indicative of the kind of performance than can be expected with 6k
records? Or a relational table? It's not very impressive, makes the member
list something to avoid, and it's undoubtedly fixable...

Even if it gets "fixed" right away, it'd still be useful to know what the
problem was.

Subject: [Zope] Trees with DTML Methods?
Message-ID: <38C9562C.8B33C8E3@pacsg.css.mot.com>

http://www.zope.org/Members/anthony/tree-coding-tricks
"How-To: Some Neat Tricks with dtml-tree"
seems to imply that I can use trees on things other than ZODB objects.

But I've been banging my head against the wall on this for some time,
and I can't figure it out.

Here's what I've got:

An index_html document:
<dtml-var standard_html_header>
<dtml-call "REQUEST.set('eid', '1000')">
<dtml-tree id=eid branches_expr="GetEmployees(eid=eid)">
  <dtml-var eid>
</dtml-tree>
<dtml-var standard_html_footer>


A DTML Method called GetEmployees that returns test data:
<dtml-if "eid == '1000'">
  <dtml-return "[1001, 1010]">
</dtml-if>
<dtml-if "eid == '1001'">
  <dtml-return "[1002, 1003]">
</dtml-if>
<dtml-if "eid == '1010'">
  <dtml-return "[1011, 1012]">
</dtml-if>
<dtml-return "[]">


What I get is an infinitely expanding tree of two pairs of 1000's:

- 1000
    + 1000
    - 1000
        + 1000
        - 1000
            + 1000
            + 1000
+ 1000

What I don't understand is how the stuff from branches_expr is supposed
to change things around.  And, not coincidentally, that seems to be the
problem with this code....

Thanks for any help.

Uuupps, Thanks. I knew I'd forget to remove it.
I already got used to reading time in epoch UTC ;-)
worldpilot.1.0.4 fixes it.
I included WPsmtplib.py and WPimaplib.py and use them now instead of the
originals to avoid dependency problems in these modules

I took a look at the imap code. it basically complains that
the SELECTed folder is not read writable.
As far as I can remember the problem may be that UW IMAP locks your
folders when they get selected.
Possibly you're accessing that folder with a different client
concurrently?

Let me know if that's the problem, since I have heard about this problem
a few times, and I thought it was a locking issue on UW IMAP.

If not we'll have to look into it.

Ryan

You are using a version of MySQL that is too new, I think.  I haven't seen this
one in a while, but I think I recognize the error messahes.  Try dropping back
to 3.22.25 (3.22.26 might work, but I know that .25 works and >.27 does not).
Send me a private email if you need a copy of the rpms.  I am sure I have thenm
somewhere

It is not inconsistent because all things behave consistently within
quotes and consistently without quotes.  You just have to know the rules
of each case.  Granted, it's not pretty, but it's consistent.

It's never used as a string because it is not a string.  You can't use
the word 'string' unless you are talking about python expressions.  DTML
does not have types, you must rely on python's expression machinery to
get down to thinking about the types of objects.

This is for security reasons.  We've overridden many of the built-in
functions like str and dir with our own so that DTML programmers cannot
do mean and nasty things, intentionally or unintentionally, from DTML.

It doesn't use the Catalog.  It's a plain Zope folder.  This means that
the folder object, including it's dictionary of childer, is loaded into
memory every time it is accessed.  This is the inefficient part. 
Folders were never meant to contain this many objects.  This is not
neccesarrily a lack, Linux directories are not that efficient either. 
Try putting 6000 files in one ext2 directory and then type 'ls'.  Pack a
lunch.

What is needed is a Folder object based on a more efficient storage
mechanism, like BTree.

I'm all for this.

And here comes the but.

But, 4Suite is not suitable (i.e. doesn't compile) for Win32 at the moment
(that's from the horses mouth, well Uche at least).

There was talk of win32 binaries but they seem to never have materialised.

I sopke to Uche today, and supposedly there are people who have had it
compile under win32. Im tracking them down at the moment. 4Suite may not be
suitable at the moment, but not because there arent win32 binaries.

I suppose line 1125 of mySQLmodule.c is something like:

Yes!  But I think that the concurrency might be happening from
Zope/WorldPilot?  I.e. that it is submitting another command prior to
the first results?  I ran (the patched) imaplib.py by itself (it has a
"sample session") which gave "reasonable" results...

Or, it might be an instance of the way recent UW imap daemons deal
with the maildir issue, copying files to the local user account from
the mail spool...  (see documentation, which I'm not yet sure that I
understand; but then again, I'm a research biostatistician, not a
sysadmin/www-master...).

I replicated it using UW imap locally on the linux (debian) box.

Maybe I'll try firing up Cyrus -- does anyone know if it "drops in" in
the same way that UW Imap does?  (i.e. install and go...).  Debian's
got it, so maybe I can do that...

Now I'm confused. You have to restart the Zope server after untarring the
package. Does WorldPilot show up on the Product Management page? If not maybe
it was unpacked into the wrong place. Did you set up the directories that are
listed in the INSTALL.txt. One change that can be made to the instructions is
the permission settings on the created directories. You can set them to 755 and
user to the user that runs Zope and group to its primary group. For example I
run zope with user jack.users so my directories look like this:

drwxr-xr-x   2 jack     users        1024 Feb 17 21:33 sessions
drwxr-xr-x   3 jack     users        1024 Feb  1 23:04 storage
drwxr-xr-x   2 jack     users        1024 Feb  1 23:04 user

The first time installed WorldPilot I think I had a permission error and ended
up with a broken product in the Product Management section.

Hope this helps.
Jack

Hi Patrick -

What happens if one manually deletes a file that is part of a transaction
involving many objects/files? How would transaction boundaries be enforced
on a filesystem? I am interested in hearing your thoughts on the issue
since it seems you have already done some work on it.

The following test was done with the WorldPilot Note facility and I suspect
would be similar in the calendar. I have three test users on the system
tester1, tester2, and tester3. I logged in as tester 1 and created 3 notes: 1
private, 1 public, and 1 confidential. I then added tester2 in the sharing page
with browse and read access. Tester3 only got browse access. Tester1 sees all
three notes, tester 2 the public and confidential, and tester3 the public. If
you have resources that need scheduling you should be able to set up userids
for the resource and let it have a calendar that is open to appropriate people
to read and/or edit. There may be a easier way to do this and maybe Ryan will
let us know if/when he sees this. :-)

I've not had a chance to work much with Exchange Server but if memory serves it
doesn't do much more than a standard IMAP server in the sense of
mailboxes and shared folders. It provides support for calendaring and address
books (with client support for LDAP, another of the things on my list of things
to learn.) So beyond that it depends on what they want to do. 

Good Luck!

Yep, although this would greatly improve my assertion that unix dirs,
like zope folders, are not efficient enough to handle 6000 objects, it
would not effect my assertion that zope folders need a more efficient
storage mechanism.

I know this is probably what you meant Patrick, I just wanted to be
explicit.

In this light, I have experimented with a BTree folder.  I posted the
code to zope-dev eariler this week.  Anyone get a change to see it? 
Anyone interested in actually improving it?

I have done nothing on this, unless you count daydreaming. ;>) At one
point, I had idly asked if anyone thought this might work, expecting
that some knowledgeable soul would immediately shoot the idea down.
Surprisingly, both Jim Fulton and Hans Reiser seemed to see that it was
in the realm of possibility, but not easy.

Of course, you have identified the hard part. Back in December, Jim
Fulton had the following reaction (below). Afterward, someone else at DC
told me that when Jim says it "getting transactional semantics right
might be a tad tricky" he means your head will explode. :)

Still ... since Linus Thorvalds has refused to add the complexity of
journalling to the Linux buffer cache, the people hacking on reiserfs
and other journalling filesystems, have been forced to implement their
own mechanisms for keeping track of dirty data. So one wonders if these
might be adaptable in some fashion, much as they are used to support
high availability network filesystems like Intermezzo, which exploits an
existing filesystem as a cache and wraps around it.

So, in answer to your question, I have no idea. ;)

===========

[Jim Fulton]
Would you imagine using the reiserfs as a ZODB storage?
If one was going to use a file system as an object store, 
then the reiserfs would be attractive due to it's effective
support for small files. Is this what you had in mind?

The ZODB has a well-defined "storage interface" that should
make implementation of a reiserfs- (or just an fs-) 
based storage reasonably straightforward, although getting
transactional sematics right might be a tad tricky.

Jim

One possible approach here is to have your proxy add a magic path element to
the path, sending http://www.mydomain.com/PATH to
http://zope-host.nipltd.com/PROXIED/mydomain/PATH.

Then have an Access Rule which says:

If "REQUEST.path and REQUEST.path[-1]=='PROXIED'" then "REQUEST.path.pop()"
and "REQUEST.setURL(path='/')".  There doesn't have to be a real object
called PROXIED, it's just a flag to be recognized and discarded by the
Access Rule.

Subject: [Zope] Zope under low Disk Conditions
Message-ID: <200003110340.NAA88677@mail.theinternet.com.au>

I've just had a few frustrating hours trying to work out what was going on
with Zope.

It stopped allowing the addition of DTML-Methods. The connection would just
hang waiting for the Method to be created (also happened with DTML-Documents).

Turns out that /tmp was out of space temporarily. -- the disk that Zope
was running on had plenty of space.

It'd be nice if it would return low disk space errors rather than go off
into never-never land.

When in doubt, read the fine manual.  The _actual_ syntax you are using is::

  <dtml-var name="AUTHENTICATED_USER">

which can be abbreviated (and is, by almost every Zopista) as:

  <dtml-var AUTHENTICATED_USER>

The "name" form of the var tag is the "preferred" one, for the types of
applications DTML is really designed for: simple scripting of objects built
in Python.  It does several "automagic" things with the name:

  - If it is callable, calls it, passing the current object, the
    current namespace, and the REQUEST;  it then replaces the object
    with the result of the call.

  - If it has a string coercion (__str__) method, calls that and
    replaces the object with the result.

This behavior is the Right Thing (TM) for simple scripting;  but it _isn't_
Pythonic (the automagic stuff smells more Perlish, really).

The "in quotes" version is really::

  <dtml-var expr="AUTHENTICATED_USER">

but can also be spelt (and mostly is)::

  <dtml-var "AUTHENTICATED_USER">

The "expr" form of the var tag evaluates the Python expression (in this case,
to the object AUTHENTICATED_USER).  For fairly obvious security reasons, the
evaluation takes place inside a restricted namespace, without the usual
builtins;  the "safe" builtins are made available as members of the
"_" namespace.

The simplest disambiguation possible is to cease using the shortcut forms, and
always spell what you really want:

  <dtml-var name="AUTHENTICATED_USER">  <!-- DWIM: give me text!!! -->

or

  <dtml-var expr="AUTHENTICATED_USER.getUserName()"> <!-- DWIS,NWYTIM -->

Hope this helps!

I now just take my log files and run it thru a script to correct the

I got a quoted version of the object if I made

It does not evaluate the tags and quoted all < with &lt; and so they all

What rules determine when it will be quoted?

Also, I got the same result if I have

I can work around with

<dtml-with folder>
<dtml-var obj>

But how can I workaround "this"?

Actually, the Members roster is a bit more efficient. It uses caching to
store the results. This was added only recently, before the roster was
offline for a while because it was taking too much resources.

What happens is this:

If the cache has expired, or is empty, we do go through all 6000 Member
folders, and check wether or not they are listed. From listed Folders (just
over a 1000 now), we store the id and title in a list. This list is sorted
on id. Next we store the total number of Members found.

Then, we loop over the 6000 Member objects, and check wether or not they
have been active in the past two weeks. The number of active accounts is
also stored.

Together with a timestamp, this info is then stored as a volatile dictionary
attribute, and returned.

A next call to Members will return this cached information. Timeout of the
cache currently is 60 minutes. So, the batched pages and the searches use
this cached information.

There are a few reasons why it still may be slow:

1/ The cache has expired or is empty: we have to fill it again.

2/ The cache is per-thread. It isn't persistent, and therefor not shared
between threads. Your request could hit on thread first, your next request a
different thread, and then have to wait for the cache to fill twice.

3/ The volatile attributes don't hang around as long as I expect them to.
Maybe the object cache is a bit too aggressive, I haven't figured this out
yet. I haven't been able to get the cache to stay around for more than 20
minutes, but it is hard to verify and debug with 7 threads. I am not sure
about this one, because in the course of some extra testing I got to see
cache older than 20 minutes again.

4/ The dictionary containing the cache may be coming from swapped memory.
Currently, the Zope.org process grows quite large. This may have to do with
the up to 42000 Folder objects loaded into memory at any time. The Members
Folder holds references to 6000 Member Folders, and there can be up to 7 of
them (7 threads). This is an area where a BTree based folder would _really_
help.

5/ Plain network lag. Check other pages on Zope.org.

6/ CPU is hogged. The rendering of the ZQR is very expensive. If it runs,
the whole of Zope.org suffers. I am seriously considering disabeling it.
People really onlly need the pre-rendered version. I was testing just now,
had to wait way too long, and noticed someone was looking at both the normal
ZQR (rendering from XML), and the print preview version. The Members roster
came from cache.

I CCed David Kankiewicz on this, so he knows =)

1000 is still too many to be efficient in a regular folder.  You're
right that a BTree is probably the way to go here.  I didn't know about
the caching efforts, it seems like you went through some hoops to come
up with a better solution.

I think that we should seriously look into or have someone in the
community look into my BTree folder efforts to come up with a better
solution.  Depending on when I wake up tommorow, I'll see if I can fix
the various bugs in BTreeObjectManager and make an alpha release.

The only big question I can think of is, should BTreeObjectManager
replace ObjectManager?  Obviously not at first, but we should maybe look
into replacing OM with a more efficient form.  Looking strictly at
performance, I don't see any reason why this should be the case.  In all
cases, a BOM should be faster than an OM.  BOM are not any less
efficient in resource consumption either, and they are written in C, not
python.  Zope's BTree implementation is also very well tested, and
written by Jim, 'nuff said. ;)

Works for me. Especially if it results in a more up-to-date version in
pre-rendered style. Pre-rendered is about 6 months old, IIRC.

I imagine Zope is like anything else (basically) you would run in a
chrooted environment. Give it the things it needs, and it should be
fine.

You may want to have alook at the Zope Product code for Zope Studio. I added
methods to the Application class, exactly what you want (watch it, long URL,
you may have to reconstruct):


http://cvs.zope.org/cgi-bin/cvsweb.cgi/ZopeMozilla/ZopeStudio/ZopeProduct/Zo
peStudio/ZopeStudioRDF.py?rev=1.2&content-type=text/x-cvsweb-markup

The important bits are 'import OFS.Application', and to assignments to class
members in OFS.Application.Application:

  OFS.Application.Application.zsTreeRoot = zsTreeRoot
  OFS.Application.Application.zsContainerRDF = zsContainerRDF

Note that the 1000 items is a sorted list of (id, title) tuples, _not_
Folder object references.

Once the cache is filled, we only have to display the precooked numbers,
take one _.len() of the listed members list for display, and have dtml-in do
it's magic on the afore-mentioned list.

The problem lies mostly in the fact that we have to access each and every
Member Folder to check if it is listed. Even if we use a BTree, we'd have to
load every Folder into memory. The same for the User objects in acl_user.

This is a side effect of using Extension Classes. From ExtensionClass.stx:

  Overriding methods inherited from Python base classes

    A problem occurs when trying to overide methods inherited from
    Python base classes.  Consider the following example::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            Spam.__init__(self,name)
            self.favorite_color=favorite_color

    This implementation will fail when an 'ECSpam' object is
    instantiated.  The problem is that 'ECSpam.__init__' calls
    'Spam.__init__', and 'Spam.__init__' can only be called with a
    Python instance (an object of type '"instance"') as the first
    argument.  The first argument passed to 'Spam.__init__' will be an
    'ECSpam' instance (an object of type 'ECSPam').

    To overcome this problem, extension classes provide a class method
    'inheritedAttribute' that can be used to obtain an inherited
    attribute that is suitable for calling with an extension class
    instance.  Using the 'inheritedAttribute' method, the above
    example can be rewritten as::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            ECSpam.inheritedAttribute('__init__')(self,name)
            self.favorite_color=favorite_color

    This isn't as pretty but does provide the desired result.

--
Another way, and I used this, is by bypassing the method binding, by
accessing the unbound method. The above example could also be:

        def __init__(self, name, favorite_color):
            ECSpam.__init__.im_func(self, name)
            self.favorite_color=favorite_color

The propertysheet variables become class variables, which are persisted as
well. So when you retrieve an instance, the persisted class that described
the behaviour of that instance is taken from the ZODB, and the new persisted
class has the .d attribute there.

In your python class however, .d is a instance variable, it gets set when a
new instance is created and __init__ is called. And exisiting instances
don't get __init__ called again, after all they were initialized already.
They only get their current state restored, and that state never included
the d attribute. Only on new instances, where __init__ is called, does d get
set.

You could get around this by making d a class variable, by adding d='I am d'
to you class definition. Alternatively, you could use the __setstate__
method, it is called when the instance is retrieved from the ZODB. It
revives the state of the object, and you'll have to remember to call
Persitant.__setstate__ as well:

    def __setstate__(self, state):
        Persistent.__setstate__(self, state)
        if not hasattr(self, 'd'):
            self.d = 'I am d'

'this' is an object reference, and it is being stringified. So the source is
returned, HTML quoted.

What do you want to achieve? Calling itself? ot very wise, as it would cause
an infinite loop..

If you want the source, do <dtml-var PricipiaSearchSource> and give the
Document a Proxy Role of Manager.

Well, here's a STUPID_LOG_FILE and a DEBUG.LOG during a crash.  I've
annotated the DEBUG LOG` as to when I think the crash occurred.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

I guess thats not the point here. Sure you can use POST for forms as
well
as GET. You can even "construct" A form-like URL for GET using
?var=value&var2=value
but you cannot send something inside forms without javascript over a
href-tag.

There is a really good Howto on the zope.org website that explains in detail how to
call a ZSqlMethod from an external method, and how to parse out the results
afterwards.  Follow those instructions and you shouldn't have any problems.  Your
email spells Extensions as 'Extentions', so make sure that this is not your problem
(probably just a typo, I know, but I thought I would check).

This might be a better idea. I'd use an external file, however.

User will alway read from file, is fast (shared locking). A cache update

This doesn't solve this. It's not the surfing of all those folders, it's the
accessing of the Members Folder itself. It's that folder that holds the
references of 6000+ sub Folders.

It is necessary when you want to call a DTML Method or Document from a
Python expression and you want that DTML Method or Document to be able
to look things up as an attribute of a 'client' or in your current
namespace (or any namespace you provide).  You can omit it when you are
using a DTML Method or Document _by name_ in DTML.  Note that:

<dtml-var IManager>

is the same as:

<dtml-var name="IManager">

and:

<dtml-var "IManager()">

is the same as:

<dtml-var expr="IManager()">

So most people use the first and third shorthand forms to use an object
by name and to execute a python expression respectivly.  When the DTML
Engine sees that you are using an object by name, it tries to do clever
things, like detect if it is a DTML object and to call the method and
pass the namespace 'magically'.

When the DTML engine sees that you are using an expression, it assumes
you know what you are doing and does no magic for you.  Therefore, you
must explicitly pass in the namespace.

> I'm also very unclear
> as to just what the 'client' is, especially since most of the examples
> I've seen involve passing in None for the client.

The 'client' is an object that you want to use as a namespace.  For
example, if DTML Method 'IManager' wants to find the name 'img' you can
pass a client object, and the method will try and do a getattr(client,
name) (in this case, name being 'img').  If you pass a namespace, then
it will try and do a namespace[name].  If neither of these succeed, it
will look for the name in the optional list of keyword arguments you can
provide.  If that fails, it raises a NameError.

The reason why it is None in most cases is because you want your method
to look things up using the Zope DTML Namespace (affectionately known as
'_').  In some special case however, you may want to explicitly provide
some other object.

This is single handedly the #1 obfusication in Zope and the most
frequently asked question.  We, of course, did not obfusicate this on
purpose.  When DTML was first concieved it worked by name only, so the
behind the scenes magic was acceptable and intuitive.  Later, we added
python expressions, and the ugliness of calling DTML Methods and
Documents became aparent.

Message-ID: <Pine.BSI.3.96.1000311155818.539I-100000@twirl.bitdance.com>

I've got a simple CatalogAware ZClass.  (CatalogAware is the only
class I added to its inheritance list.)  Everything seems fine,
but if I access an instance of the ZClass through the Catalog by doing, say,
getobject(data_record_id_), and then inspect the 'id' property of
the returned object, instead of getting the id of the object I get
the id of the folder in which the Catalog lives.  When I create
class instances, the 'id' in the meta-data is correct.  If tell
the catalog to update itself (or tell an item listed in the catalog
to update itself through the catalog management screen), then
suddenly the metadata id is also the id of the folder enclosing
the Catalog.

Is this a bug, or am I doing something stupid?  The object appears
under its id in all of the management screens, including the 'indexed
items' tab of the Catalog.

Hi DTML Gurus,

I am a newbie with DTML and i am trying to do the following with this script

1) using the subdirectory RegisteredUsers, check if a ZClass object of type
Player exists in the RegisteredUsers directory with an id that matches that
in the Request ( a form from the client ). This currently doesnt work for
some reason and i get the else case even if the object does exist.
2) In the else case i am then trying to create a new object of type Player
 a ZClass object defined in the GameSite product ).  I am creating the
object correctly in the correct place but the next bit of setting the
properties of  the player object does not work, and the object properties
are blank.

HELP !!

I have checked all the documentation for zclasses, dtml faq etc.  Can any
one help?

Is  there an easier/better way of achieving what i am trying to do, or am i
barking up the wrong tree ?


<dtml-with RegisteredUsers>

<dtml-if REQUEST['new_user_name']>

User currently exists

<dtml-else>

New user

  <dtml-with "manage_addProduct['GameSite']">

I think I heard somewhere that it's now equal in speed to CPython, but 
I'm not sure. People use it to script Java components and such. It seems
to be reasonably popular for things like that in Java-land.

[snip explanation why open-source like collaboration is harder for languages]

It's hard for language *design*, yes, but it's less hard when you're doing
language implementation (for instance a faster one), and it's easier still
when you're writing libraries and such. And it does happen for language
design as well -- the Python static type design is currently being fleshed
out (in bursts) by the types-SIG (though of course Guido does final
approval about what goes into Python proper).

Hm, I'm not entirely sure how to find it other than digging through the
types-SIG mailing list. Try something mid-january.

You'll find some of my silly messages too. :) The types SIG came quite
a long way after Guido proposed closing it down for inactivity. It's a bit
more quiet now, I believe.

There are various tools out there for Python which do offer this kind of
functionality, though, I think? Check at the vaults of parnassus sometime:

Why not use a relational database? Is it too immature that way?

I think I see what you are trying to do here, but I don't think
DTML works that way.  The array reference is a python expression,
so you have to go to an expr.  But if you just enclose the above
in quotes you'll be testing whether or not REQUEST has a non-null
new_user_name variable.

One way to do what you want would be (tested):

<dtml-with RegisteredUsers>
  <dtml-if "new_user_name in objectIds(['Player'])">
  User currently exists
[...]

REQUEST is on the name space stack, so new_user_name will be found
without having to refer to REQUEST explicitly.  'objectIds' returns
a list of object ids, and the argument gives a list of meta_types
of the Ids to return.  So this call results in a list of just the
Player ids.  The python 'in' operator checks to see that the
left hand string is a member of the list of strings on the
right hand side.

Note: you'll run into some interesting issues with your planned
setup of the number of players gets large (say that large is several
hundred) due to practical limits on the capacity of Zope Folders.

Well, you may want to take a look at GUF and perhaps the (RealSoonNow) the
Portal Toolkit, but they may both be overkill for your application.
It depends on just what functionality you are trying to put into
your Player objects.

I forget which How-To I got this out of (maybe the CatalogAware
How-To?), but I think the call to update the property list function
name is (copied from some of my own code):

propertysheets.<your-sheet-name>.manage_changeProperties

Since your cut and paste dropped some stuff there, though, that may
be what you have, in which case I don't know why your properties
aren't getting updated.  Though you might try adding the _.None,_
arguments to the beginning of the call.

I'll repeat my question; why not use a relational database? Do you
need an object database? How is the ZODB too immature?

I'm having some trouble with it too, but perhaps that's just not being
familiar with the concept yet. But at least it looks less horrid than
some map()s and such.

Why so? I myself think Zope's source is an argument for explicit interfaces. :)

Well, tuples can be used as dictionary keys, lists cannot.

Forcing a *copy*, implicitly? But Python works with reference semantics
only? It's be nice to have a way to declare stuff immutable, I think,
but I'm not sure how often one would need to use it. There's something
to say for knowing something's a tuple, instead of having a list and
having to know whether it's immutable or not. Though perhaps that's
not a big problem in practice.

But that might result in a lot of incomprehensible code. I'm not sure if 
I'm in favor of having 'out' parameters anyway. constness as defined in
C++ is also tricky, as it infects code; everything that touches it
needs to be const-correct. Python tends to be less strict in this area.

[optimized statically typed modules calling classic python modules, why
is this tricky?]

Yes, it is doable but tricky in combination with static typing. See
the types-SIG for more info; I believe Guido has some messages on that.

Strange problem here - likely not related to Zope directly.  When our
content guys edit the DTML through the Zope management interface in IE 5.x,
the pages are properly displayed in IE 5.x (and assume 4.x).  However, in
Netscape, some pages do not display properly.  After running the DTML though
a code validator, the results indicate that the H/DTML is correctly
formatted for IE/Netscape 3.x and above.  We're aware of the normal
differences in table formatting, for example, between the different
browsers.

However, viewing the pages in Netscape 4.x, the source has all the "<" and
">" replaced with question marks.  This has been tested in Windows 98/NT 4.x
and Linux RH 6.1.

Now, I'm open to suggestions.  I am tempted to think this is a result of
some encoding issue, or perhaps  IE 5.x's handling of extended characters
but I'm at a loss.

This is likely some silly setting that we've overlooked but I thought I'd
check here first.


Thanks in advance,

I've seen that behavior under Linux Netscape when viewing some sites.

Having worked with C++ for a long time, and later with Java,
I can tell you just how much I hated the whole thing about
data "encapsulation."

The whole mumbo-jumbo stuff about data hiding has one and one
single purpose: divide the programmers into engine programmers
and app programmers, so the engine programmers and exercise
full control over app programmers. It has more to do with
MONEY and corporate POWER CONTROL than with technology.
The private/protected keywords are an enterprise feature...
designed for big companies.

And generations of students are taught into this stupid
c**p about "data encapsulation." Funny thing is, many actually
buy the idea, get burnt for a few years and refuse to
acknowledge they are being burnt ("if it is mentioned in
textbooks, there must be a reason... it must be good for me..."),
and only then to realize much later... hmmm.... maybe
"data encapsulation" should be done by convention and not by
syntax.

Yes, another thing that I consider to be stupid in C++ is the
overuse of const, or its use at all. Again, generations of
programmers are taught into this thing about usage of const,
and buying into it without questionning.

Python uses references for object parameters in function calls.
It can also return tuples. That's enough. Really.

Keep Python simple. The role of Python is CP4E (Computer
Programming For Everyone.) In Java or C++, you have to type
all the extra stuff about public/ private/ protected/ void/
abstract/ static/ synchronize/ final/ const/... before you can
do something. I know many people that live in that world and
refuse to simplify their lives... well, then again, I also
know people that lives in the Perl world and insist that Perl
is a very readable language. :)

So to keep all start tags and end tags in the same object.

I can do that for a folder by making the method call index_html and call the

But I want to publish anyobject by adding this method to it:

abc/publish

will warp abc with the apropriate html codes which traditionally in zope is
done by header, var, footer. which might result in the opening tags in
header and end tags left in footer.

Subject: [Zope] Redirection problems
Message-ID: <20000311202916.B8706@magellan.midsouth.rr.com>

Right now, visitors to my site at http://www.centralchurchyouth.org go
through the following redirection:
http://www.centralchurchyouth.org (running IIS)
	to
http://www.centralchurchyouth.org:8100/ (running Zope)
	to
http://www.centralchurchyouth.org:8100/Home/ (the real home page)

This works in Netscape but doesn't work in IE. The user gets all the way
to the third page but it doesn't render. Upon further analysis, all of
the absolute_url calls (like "<dtml-var "stylesheet.absolute_url()">"
produce http://www.centralchurchyouth.org/xxx instead of
http;//www.centralchurchyouth.org:8100/xxx, so the page has a broken
logo, etc.

I think it has to go with the HTTP session between IE and
http://www.centralchurchyouth.org:8100/, but I'm not sure what. Using
wget also returns a correct page.
Surely someone has come across this issue.

[snip]

Having worked with C++, Python, and Object Pascal for a long time, I
tend to agree, with a few modifications:

- encapsulation helps keeping the code self-documenting -- nobody can
accidentally access hidden members;

- it aids documentation tools in that visibility rules can be seen as
metadata -- "source navigator"-type object browsers can categorize
members (methods and data) into their various protectedness; and

- most significantly, hiding data and replacing direct access with
clearly defined accessor methods lets you control access (such as
synchronizing access from multiple threads) and also provide behaviour
-- often data is calculated on demand rather than stored, and often
related objects must be notified when data is changed.

Python doesn't have accessor methods, but uses __setattr__ and
__getattr__() instead, which is less intuitive -- a code browser cannot
easily infer the access interface from the class definition alone -- and
certainly slower -- but also more flexible. 

I'm a big believer in pure-code interfaces, keeping data hidden and
restricting all reads and writes to accessor methods; languages such as
Dylan and Object Pascal fortunately have accessor-method support built
into the language, so referencing an attribute foo.name would actually
be resolved by the compiler into a call to foo.GetName(). Python doesn't
really need this, since its attributes are all dictionary-stored.

Btw, as for private data members that are very specific to an
implementation of a class, Ada95 solves this quite elegantly through
packages, which are similar to C++ namespaces. I don't remember if Ada
has language-assisted accessor method support.

Const is overrated but often useful. Given C++'s absolutely antique
object paradigm -- heap-based objects that aren't garbage-collected,
meaning you end up dabbling with pointers *a lot*, or use confusing
reference-counting smart-pointer template classes that go all over the
place -- I like pass-by-reference better.

I'm absolutely annoyed with C++. This is one reason:

  class Foo;

  class Bar
  {
    Foo F;
  };

  class Foo
  {
    Bar B;
  }

This, of course, won't compile -- the class Foo is undefined at the time
Bar is declared. This means that a class A cannot contain a member of
another class B if B already contains a member of class A, unless one of
them stores the member as a pointer reference. This certainly screws up
any reference-counting smart-pointer scheme, or at least makes it bloody
hard to keep simple.

Readability and verbosity are not the same things. Java is at least an
improvement on C++'s readability, but it is occasionally perhaps too
verbose. But not compared to, say, Dylan, which has keywords like
"required-init-keyword"; in spite of this, it's a great language once
you get used to it.

I rather like Borland's Object Pascal myself. It's suitably verbose to
be readable, strict enough to catch most trivial errors in the
compilation phase, statically-typed enough to perform really well, and
just plain likeable. It doesn't have operator overloading, parameterized
classes, multiple inheritance, or synchronized members, although it does
have interfaces, static, abstract, const, and member visibility
constructs. Here's the above snippet in OP:

  type
    Foo = class;

    Bar =
      class
        B: Bar;
      end;

    Foo = 
      class
        F: Bar;
      end;

(And this compiles.)

Indeed, but do I need to remind you that we're still at version 1.52?
:-)

And as for your argument that OSS boosts language implementation, true
in theory, but sitting down with a compiler and changing it, or building
a compiler from scratch, is a daunting and time-consuming task. I have,
certainly, thought about building a native-code compiler for Python. But
no time right now.

Your comments are well received. I hope I can put my own comments to
shame in the future by committing some of my resources to the Python
effort. As for the types-SIG, I've read through Guido's latest proposal,
and found it so-so; I have some comments about the syntax -- which IMHO
is heading in the right direction, but I feel it's still quite
unpolished, like the new "decl" keyword and the very odd, un-Pythonic
"->" operator. Other than that, it looks a lot like I had in mind
myself.

Interestingly enough, I'm discussing this with Jon Udell on his Byte
newsgroups (go news.cmpnet.com). I'll quote something I wrote in this
discussion, slightly edited for clarity:

<quote>
I can't easily tell Zope that objects of type A refers to objects of 
type B (mutual relationships), and that objects of type B should not 
be deletable as long as an object of type A is referring to it 
(referential integrity). The only kind of relationship Zope knows 
about is containment, a parent-child relationship. There is simply no 
other way for an object to refer to another object.

Consider the case of news articles. Let's say articles should be able 
to hold multiple sections of text, as well as images. Assuming we use 
Z Classes and not Products, two solutions come to mind: Either (a) let 
an article be a descendant of Zope's folder or object manager 
classes, and thus contain any such sub-data as objects -- a design 
which currently is the most useful, but which has its shortcomings -- 
or (b) let sub-data exist as objects elsewhere in the ODB, and have 
string attributes on the article object that refer to their names, 
eg. an attribute "Illustrations" of type "lines" containing image IDs 
such as "mayor.jpg", "airplane.jpg" etc. This is obviously ugly -- 
for example, these image objects could be moved or removed and the 
article object would never know. As for dividing article texts into 
multiple sections (page 1, page 2 etc., with appropriate headings), 
this is obviously pretty simple with scheme (a), but in the case of 
(b), the text could exist in one large attribute, and some sort of 
page tagging system might be enforced -- or we could go all the way 
and do XML. So far, with these solutions, we'll survive. Cracks begin 
to show when we start thinking about organizing authors, 
publications, and document flow.

Zope doesn't provide a framework to solve this things. Equally worse 
is that the ZODB hierarchy is so easily polluted with things that 
don't belong there. You end up putting a lot of objects in the root 
folder because they're needed globally -- and anyone who has used 
Zope will tell you that a folder becomes unwieldy and disorganized 
when it grows past 20+ objects. (Case in point: Personally, several of 
my Zope sites have a root-level Utils folder containing oft-used 
External Methods, because they tend to pollute the whole namespace.)
Zope needs a multiple-root, "multihomed" hierarchy. Z Classes must
be able to exist anywhere, not just in the one Products hierarchy.

No, although that's a clever trick. Hey, do it again! :-)

What you cite above may mirror the effect of an enumerated type, but it
doesn't contain any meta-information about the type itself: That is,
FOO, BAR, BAZ are integers. They will fit into any integer expression
and can be passed to any function taking integer arguments. The function
won't balk if you pass a value from another "enumeration". Another
problem with the above is that there is no way to ask Python to
enumerate the values or names in the sequence, because its values are
part of the top-level namespace -- I don't like that kind of namespace
pollution.

Instead, perhaps, this:

  class Enum:
    def __init__(self, Value):
      self.Value = Value
    def __int__(self):
      return self.Value

  class DeadParrot(Enum):
    FOO, BAR, BAZ = range(3)

  def PetShop(P):
    if int(P) == DeadParrot.FOO:
      print 'It''s resting.'

  D = DeadParrot(DeadParrot.FOO)
  PetShop(D)

...But hardly elegant.

And that makes sense to you? I don't know the historical significance of
tuples in Python -- I know the mathematical meaning, but Python tuples
aren't quite it -- but it smells a lot like an interface that has been
fit to the size of the implementation. A lot like, coincidentally, a
procrustean bed. (Coincidentally because the term has popped up a lot
lately; see the Byte thread.)

I think the idea that mutability as a behaviour is distributed among

(No, it would not -- it would effectively give you both "out" and
*pass-by-value* parameters.)

The alternative is returning dictionaries or tuples, is it not? Maybe
I'm not thinking in a Pythonic vein. Maybe

	A, B, C = GetABC()

is more immediately grokkable than

	GetABC(A, B, C)   # assuming these are "out" parameters

Well. Sure it is. Damn, I think you're right. ;-)

Subject: [Zope] Calling a Z SQL Method directly
Message-ID: <6rwvn824kh.fsf@franz.stat.wisc.edu>

I am a little confused about how to call a Z SQL Method directly from
within a DTML document or a DTML Method.

The application is web-based access to a bibliographic database.  I
have one Z SQL Method that looks up publications by author names, or
by words in the title, or by keywords.  I set up a search interface to
that method.  I am now trying to modify the DTML Method for generating
a report from such a query.  I have read the Z SQL Method User's Guide
but apparently I haven't understood it completely.

To make things definite I will describe a simple case.  Suppose I look
up one author's name.  The Z SQL Method is called search_author.  The
columns it returns include the "id" for each reference listing, the
"type", the "year", and the "title".  I have also created a Z SQL
Method called return_authors that takes a single argument "id" and
returns the names of the authors, one per row, in the correct order
for the publication.  Another Z SQL Method, return_journal, also takes
an "id" number and returns the title of the journal, the volume and
number, the beginning page and the final page of the article.

While I am processing the results of search_author in the DTML method,
I would like to be able to call return_authors and return_journal
directly.  It is not clear to me how I do this.  I had hoped that I
could use a dtml-in tag to call these methods while I was within
another dtml-in but either I am misinterpreting the effect of dtml-in
or I haven't got the sequence right.  What I was trying looked like

<dtml-in search_author size=50 start=query_start>
 ...
        <tr>
          <td><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
	  <td><dtml-in return_authors start=query_start>
                  <dtml-var name>;
              </dtml-in></td>
              <dtml-in return_journal_info start=query_start>
                  <td><dtml-var title></td>
                  <td><dtml-var vol null=""></td>
                  <td><dtml-var bpg null="">-
                      <dtml-var epg null=""></td>
              </dtml-in>
        </tr>
 ...
</dtml-in>

I was hoping that the <dtml-var id> from within the <dtml-in> loop
would be propagated to a call to return_authors or to return_journal.

I understand that I can use a URL to call the Z SQL Method but I am
hoping I can do it "inline", as it were.

I would appreciate any suggestions.

Douglas,

ZSQL methods can be passed arguments.. e.g.

<dtml-in expr="return_authors(id='123')">
...
</dtml-in>

In the case that the 'id' value you want to pass in comes from REQUEST
or another namespace, you can use it:

<dtml-in expr="return_authors(id=id)">
...
</dtml-in>

The _.render() method will do what you want:

  <html><head>....</head>
  <body><table><tr>...

  <dtml-var "_.render(this())">
  </tr>
  </table>
 ....

you need a folder called "import" in the same directory as your zope
installation.  Then go into zope, click "Import/Export" tab at the top,
and enter 'filename.zexp' in the "Import file name" field.

then click "Import".

That should be it!

I'll take a stab at this:

Quantity of data doesn't tip the scales towards Zope or SQL.

If you have small units of data that change frequently, SQL, using a
non-transactional storage like BerkleyStorage, or packing frequently are
all reasonable approaches.

If you have a number of large (multimegabyte) files, the filesystem is
probably the best place for them, with something like LocalFS.  Also
nice because you can have a "real" ftp server serving the files, but
still use zope to reference them.

If your data expresses several many->many relations, a relational
database may be the solution, but don't underestimate the power of
Zcatalog. for data expressing one->many relationships, ZODB rocks.

In your example, I would use the ZODB because emails are always
hierarchical, and use Zcatalog to let people slice & dice it. The
articles would depend on what views you need to put on them and what
metadata you want.

You can also do some super neat stuff with ZODB+SQL, as the very
illuminating 
Zope Question : Virtual folders / URL's thread is illustrating.

I've done some really neat things (like securing the management screens)
with SiteAccess that I couldn't dream of doing any other way.  I've
never seen SiteAccess perform in any unadvertised fashion.

Anything that lets me have less than hundreds of zopes is a good

Let's say I have a TinyTable populated with some data.  I have a DTML
method that displays it all pretty like.  What I do *not* want is
someone seeing the TinyTable itself, so I give "access contents
information" to anonymous, but deny "view".

AFAIK.

This might be possible. I'm checking the IMAP code. Possibly we'll need
to use EXAMINE on some spots instead of SELECT.
Maybe there's a race situation which would explain why it works for some
and for some not.

If heavy copy operations are involved then that would support the race
situation.
We use debian, too, so we'll try to replicate the behaviour here, too.

Cyrus is better scalable and has cached indexes. furthermore mails are
stored in individual files instead of in mailbox files.

Use the DateTime Object, in python:

Py$ from DateTime import DateTime
Py$ DateTime() > DateTime('Jan 1, 1999')
1
Py$

in DTML:

<dtml-if "_.DateTime() > _.DateTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Calling the DateTime object with no arguments means 'now'.  It accepts a
number of different date formats.  I just made this one up and it
happily accepted it.

In DTML, _.DateTime is synonymous with the global value ZopeTime.  So
the Second example is equivalent to:

<dtml-if "ZopeTime() > ZopeTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Hi,

we started a new service for our online newspaper, that is served by a Zope
server. (http://rz-anzeigen.de) We currently experience the problem, that the
machine serves really well and also during the high traffic times. But
sometime in the early morning the Zope process crashes. Now I like to know if
it is possible to get some more specific out from the Zope server when it
crashes. Can I activate some kind of logging to monitor this, or something
else that helps me to deal with this? Or is my only option to start the Server
    form the shell and see what traceback I get?

Bye, Oliver

I have this

    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltecimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

IIRC the logic that puts in BASE tags ignores the port number.

It was a simple change (removing an if section) somewhere to fix it.

I did it in old bobo-based app so it may have changed by now.

Jo,
Thanks for your C expertise.  The changes you mentioned were all that was
needed to get the MySQLmodule to compile and the MySQLDA to work.  I now see
the ZMySQL Database Connection in my list of available items in Zope!!! (big
smile).

I will eventually want to get Andy Dustman's MySQLdb connection to work,
because it is multi-threaded.  But for now I will stick with what works,
learn how to tie Zope to MySQL and THEN go for the upgrade to MySQLdb.

Anyway, thanks again for taking the time to solve my problem.

Eric.

Subject: [Zope] Problem with Images
Message-ID: <LOBBJLLPAJLLCKOOOAGFOEADCCAA.gelhaar@compuserve.com>

I've got a problem with the image class. I use Zope 2.1.4 (downloaded from
http://yyy.zope.org/) with Windows 98 second edition.
Let me give an example:
1. I create an image object head_1 and upload an image "cat". Everything is
fine.
2. I upload an other image "dog". Almost nothing happens. The image is not
there. But something has changed: The size properties. What ever I do, I do
not get the right picture, I will see always "cat" but always in different
sizes, the size from the last uploaded picture.
But that's not all.
3. I delete the image object head_1
4. Create a new one, let's say head_2 and give it an image "dog". I see dog.
5. But now, when I rename the image object from head_2 to head_1 I will get
again the old picture "cat".
This scenario is always the same, regardless what I do:
* shutdown the database in between
* clearing the undo buffer
* new installation
* hide the python installation dir
* delete the database

I played around with the lib/python/OFS/Image.py. But I experienced enough
with Zope thus I know Python. What ist wrong with me or the Image class.

Help

I've been asking this list the very same question for quite a while.  There
are a few debug How-Tos that may help, but it's all very dependent on you're
configuration as to how much extra work will be necessary.  Can you give me
more details of your configuration?  What are you using for connection, are you
going through Apache, if so using what service (PCGI,FCGI,HTTP_Proxy)?  

We have several sites up and running with Zope and have found that when there
is /manage activity occuring during a time of moderate traffic we have frequent
Zope restarts, it can't stay up more than 5-20 minutes.  To date I've found no
reliable method of tracking what is causing these, though I've created a bunch
of monitoring and debuging tools to try.  These tools are not written up yet,
but I'd be happy to send out an explaination if you would like.

It is also very easy to create code that will crash or loop the Zope server,
these are easer to find since usually as soon as the object is called Zope
reacts adversly, crashes, slows, etc.  The problem using logs for this is log
entries are usually written post completion.

Good luck.

This is almost certainly because your browser has cached the image.
Try clearing your browser cache.  Or better yet (because sometimes
clearing the cache on some browsers doesn't seem to completely
clear it), try loading the thing from a browser that hasn't
looked at that image before, and you will probably see the correct
image.  At least, that's how it worked for me when I ran into this.

Do you know about STUPID_LOG_FILE?  Put that variable in your
environment when you start Zope, and Zope will write some stuff
to the specified file.  This info may or may not show something
when Zope crashes, but it is worth a try.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

Subject: [Zope] How do you Restrict ZServer socket connections
Message-ID: <14540.5250.770668.306712@erdos.totient.co.uk>

Hi 

I've followed anser's How To on "Apache and ZServer (NOt CGI)"
and now I have Zope served thru Apache via module ModProxy and the
SiteAccess Zope Product.

Fine, But Now I want to make Zserver only accept connections from
a set of known IP address (ie that where my apache server runs)

Any ideas how you do this? I can see there are options to say
which ports it listens on but no mention of restricting the
IP addresses it allows to connect.

Thanks

Jon

Ive been having a similar problem. The problem lies not with Zope, but with
your browser and its cache. As long as you are trying to retrieve the image
from the same URL, your browser will grab the cached image rther than the
one from Zope. I havent delved into this, but I think adding some content
expiry info to the 'view' tab might be necessary. Either that or change your
browser settings.

You can connect to the database from the mysql command line utility?

ZServer does not do this interally, however there is a very secure and
popular program called tcpwrappers that does.  Your system probably
allready comes with tcpwrappers.

How to configure it to work with ZServer I don't know, but it shouldn't
be hard.  Consult the tcpwrappers docs.

If you are using Linux, this job is best done with
the firewall itself (like ipchains.) Otherwise it
is not very secure.

That being said, inside Zope itself, you can put in your
index_html (or equivalent)

<dtml-if "REQUEST.REMOTE_ADDR != '127.0.0.1'">
  <dtml-return "''">
</dtml-if>

Of course, you can return a nasty message, or redirect
the request to some other web addresses by using
<dtml-var "RESPONSE.redirect(...)"> :) If you are using
SiteAccess, you can put a hook at the root folder to
bounce off anyone that you don't like.

The REQUEST variable holds other environment variables
that might be of your interest. You can either use

<dtml-var REQUEST>

to print out the variable content, or simply append
/REQUEST to your URLs when you are browsing a Zope
site:

http://your.site.name/yourfolder/yourpage/REQUEST

Subject: [Zope] Generic User Folder Gotcha
Message-ID: <20000313105937.B4444@bob.sesgroup.net>

Just thought I'd let people know about a small gotcha in the GUF.

If you do not have a user folder in the root directory and then create
a GUF in a subfolder using cookie-based permissions it will lock you
out of that folder.

GUF works fine in this situation if you use basic authentication just
not with cookie based. The problem is that in cookie based authentication
method it never checks whether you are the super user or not. It works fine
if you have a user folder in the root becuase it then goes and checks it.

I tried some code to get around it but didn't really have time to fix it
esp when it is trivial bug/feature? to get around.

Anyway just though this might save some people some time along the way.

Oh and thanks to Zen GUF is a fantastic product !

Cheers,

Benno

Take a look at the dtml-try tag in the dtml documentation.

Message-ID: <B059671903C6D211A0D500C0F0301C792B2697@kubrick.mop.no>

Like so, for example:

	<dtml-var "MyDate.toZone('GMT')" fmt="ISO">

Date-time math is very simple with Zope's DateTime objects. DateTime
supports fractional, C-type clock values -- 1.0 is one day, 0.5 is half
a day, 1 / 24.0 ~= 0.0416 is one hour. So,

	<dtml-var "(ZopeTime() + 1).toZone('GMT+5')" fmt="ISO">

gives you the time tomorrow, adjusted to GMT+5. You can use named time
zones such as "US/Eastern".

Helmut,

I doubt it.  It's probably a username/password/databasename issue.

My suggestion would be to set up mysql to accept a null login (no
username, no password), create a database in there called "test" and
connect with the connection string "test@localhost"

I don't think this is a bug in WU or a concurrency issue, I think it's a
funky design decision in imaplib.py

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import imaplib
>>> server = imaplib.IMAP4('X.X.X.X')
>>> server.login('michel', '******')
('OK', ['LOGIN completed.'])
>>> server.select('Public Folders/Mailing Lists/Zope Folder')
Traceback (innermost last):
  File "<pyshell#8>", line 1, in ?
    server.select('Public Folders/Mailing Lists/Zope Folder')
  File "C:\Program Files\Python\Lib\imaplib.py", line 468, in select
    raise self.readonly('%s is not writable' % mailbox)
readonly: Public Folders/Mailing Lists/Zope Folder is not writable
>>> 

server in this case is a Exchange box.  There is nothing in section
6.3.1 of rfc2060 that says this should fail.  The imaplib authors
however seem to have felt otherwise, which is why there is an optional
second argument to IMAP4.select():

def select(self, mailbox='INBOX', readonly=None):

Passing a true value to the readonly argument will allow you to select
the mailbox, as shown:

>>> server.select('Public Folders/Mailing Lists/Zope Folder', 1)
('OK', ['964'])
>>>

Try the DebugLog, this is an as yet undocumented feature of Zope:

http://www.zope.org/Members/mcdonc/HowTos/DEBUG-LOG

This will show various state transitions of requests.  This helps
pinpoint, for example, if your problem is a ZServer or an application
issue.

Subject: [Zope] Python or C Library error?
Message-ID: <NDBBLBELNHAPHBBCOIFDKEMGCBAA.ewalstad@energywright.com>

Well, I thought I had it working...

I am trying to get MySQL to work with Zope.  I installed ZMySQLDA and was
able to make a connection to a database.  I was even able to make an SQL
method that added records to the table.  However, when I added a method to
lookup a record in the table, I get the following error when I "Add and
Test" it from Zope:

Error, exceptions.ImportError:
/usr/lib/python1.5/site-packages/_mysqlmodule.so: undefined symbol:
Py_InitModule3

This is the same error I got when I tried to install MySQLdb.  That's why I
tried to install  MySQLDA instead.

However, I can't tell if this error stems from C or from Python.  I don't
know much about Python (the book I ordered isn't here yet), but it looks
like the error is starting there.

If anyone has run into this error before, or has a clue as to how to fix it,
please let me know.

OR, if you have a working Zope/MySQL combo and wouldn't mind sending me a
copy of your '_mysqlmodule.so' binary, maybe that would do it?

Thanks,

Eric.

This is kind of a distressing message Tony, we'd very much like to see

Yeah ;) But whats with comparing wether we are between hour xx and hour
yy 
every day? Or even between 0:00 and 1:15 every day...
This comes up with very strange hassle with DateTime() and strings and
int() 
and so on...

Or is there a better way?

I've never used MySQLDA without MySQLdb.

I would try to follow the steps in the howto that deals with installing
mysql (including the steps for installing MySQLdb) in order to get the
thing working.

It sounds like you couldn't compile MySQLdb because you didn't have the
right libraries for MySQL.

I saw that, too, but wasn't sure if it behaves the same, because a few
lines further up if that parameter is true then it uses EXAMINE instead
of SELECT. I haven't made it yet back to the RFC's to check in detail
what the exact difference is between the two. If EXAMINE is OK for 
write operations as well, then that would be fine. But it sounds like
it's intended for following read only operations only. I'll check it
out...

Cheers,
Ryan

DateTime works at one one-thousandth of a second resolution.  Hours and
minutes are no problem.

No hassle that I can see, no more so than any other kind of object that
would do this.

There's mxDateTime, which I believe works similarly to DateTime.  I
don't think one is any 'better' than the other.

Subject: [Zope] RFC: Flaws in Structured text
Message-ID: <B059671903C6D211A0D500C0F0301C792B2699@kubrick.mop.no>

I would like to outline a few problems, based on
observations of real-world usage, with Structured text.
Comments are appreciated.

As much as I like the format, the current syntax is either
too loose, or the transformation logic too dumb, resulting
in text that does not come out quite as expected. There are
workarounds for all such problems, but authors and editors
aren't aware of them, and continually make the same mistakes
over and over again.

Here are a few gotchas:

- Lines starting with the text number-dot (eg., "1.") are
considered to be bullets.

  Problem: In other languages, and sometimes in English,
  this is a valid non-bullet introduction. In Scandinavian
  languages (Norwegian is the language of my country), for
  instance, "1." is an oft-used way of spelling "1nd" or
  "first" ("2." for "2nd" or "second", and so forth). My
  experience is that this occurs frequently.

  Solution: Avoid transforming such paragraphs into bullets
  when they occur adjacently to valid non-bullet sentences,
  and only apply the transformation when the number is
  higher than the preceding paragraph. Validate the number
  itself -- today you can write
  
    43423. Something
    
    24324. Something else
    
  and it's still transformed into 
  
    <ol><li><p>Something</p><li><p>Something else</p></ol>

- Lines starting with dash-space (eg., "- The") are also
interpreted as bullets.

  Problem: As with number bullets, this clashes with non-
  English conventions. At least in Scandinavian languages,
  quotes are often given using a preceding dash. Here's an
  actual example, translated to English for clarity:

    - Pooh, said Rabbit kindly, you haven't any brain. - I know, said
Pooh humbly. 

  Solution: Make this feature optional.
  
- Em dash sequence ("--") usage clashes with definition
lists.

  Problem: People, including me, frequently use an ASCII
  form ("--") of the em dash ("-"), in the absence of this
  character in the 7-bit ASCII character set. (Actually,
  what *I* want is an en dash, which ISO provides.) This
  transforms into a HTML <dl></dl> list, even when the dash
  occurs late in the paragraph.
  
  Solution: Only transform paragraph to definition list if
  the dash sequence follows the first, dot-terminated
  sentence, like so:
  
    This is a definition term. -- and this is the definition
    itself.
  
  Not sure whether this is ideal. It would likely break old
  stx documents. Perhaps a "force literal" control character
  can be introduced, like the "\" token used in Python, Perl,
  C, etc.
  
  Note to self: There ought to be a way to transform such
  poor-man's dashes into en/em dashes, and quotation marks
  to "smart" quotation marks.

- Link transformation into HTML anchors tags is poor, or at
least too rigidly parsed.

  Problem: Some examples of links that do not work:
  
    The document (found "here":http://www.zope.org).
    
    <dtml-var "'This is a \x022link\x022:http://www.zope.org/'" 
      fmt="structured-text">, 
   
  I'd love to give cite other annoying cases I've come
  across, but I don't remember them. ;-)
   
  Solution: Tolerate parantheses, and accept that URLs that
  are terminated with end-of-line. Provide better syntax for
  specifying URLs, such as this:
  
    A product called Zope (http://www.zope.org) can be found
    on the _Zope site_ (http://www.zope.org).
    
  which would be transformed into:
  
    A product called <a href="http://www.zope.org">Zope</a>
    can be found on the <a href="http://www.zope.org">Zope
    site</a>.
  
- Structured text code should not wrap transformed text in
paragraph tags (<p></p>), or should at least make this
wrapping optional.

  Problem: I often display stx in places where a new
  paragraph creates unnecessary vertical padding that
  violates page design -- for this purpose I have been
  forced to write a simple External Method that removes the
  offending paragraph tags. IMHO, this ought to be
  unnecessary.

  Solution: Provide necessary option.
  
- Structured text code not available to DTML.

  Problem: The code is only available to External Methods
  and products. DTML can only get at stx through dtml-var's
  fmt attribute.
  
  Solution: It would be swell to have an _.stx() or
  StructuredText() construct.

Define "top-level namespace"?  This is one of my favorite things about
Python.  You get the behavior you want below *for free*, because modules
are done the Right Way (tm).

'-- spam.py ---
| FOO, BAR, BAZ = range(3)
| 
| class Spam:
| 	def __init__(self,foovar):
| 		self.var=foovar
`--
'-- eggs.py --
| import spam
| can=spam.Spam(spam.FOO)
`--

Alternatively, if eggs.py uses spam.py heavily, and is closely integrated
with it:

'-- eggs2.py --
| from spam import *
| can=Spam(FOO)
`--

I use both styles -- and you can choose!  Clean namespaces, or terse
syntax -- voluntary namespace pollution.  You can even be selective (and
this can really be fun) with expressions like:

'-- eggs3.py
| import spam
| FOO=spam.FOO
| Spam=spam.Spam
`--

if you're heavily using FOO, but not BAR or BAZ in eggs ...

For some strange reason, although they have come under lots of fire,
tuples make perfect sense to me.  They don't seem to confuse new
programmers much, either, since I've been introducing lots of people to
python...

For example; lists used as dictionary keys, if mutable, would have all
sorts of confusing effects.  Class instances, being explicitly references,
don't have this problem; but if you pass a list in as a dictionary key,
change the list... what should happen?

class A: pass
x=[]
q=[]
# you may want to think of that as
# q=copy(x)
# instead
y={}
z=()
a=A()
b=A()
y[a]='a'
y[b]='b'
y[z]='z'
# broken, but to prove the point
y[x]='x'
print y[q]

The same thing goes for strings... I dunno.  Type-defined mutability makes
a lot of sense to me.

Doesn't that just *look* nice?  This is certainly how I'd write this
happening in pseudocode, and I was overjoyed to find that python did it
automatically.

> is more immediately grokkable than
> 
> 	GetABC(A, B, C)   # assuming these are "out" parameters

This style is BAD BAD BAD.  I don't like having my variables manipulated
by functions, if they're mutable... but it would be even WORSE to have the
symbols actually changed!  Nonsense like this contributes to some of the
least readable code I've ever seen in C and C++ ... ugh.  I *wish* you
could return tuples in C++ =)

(The worst part about this is that SOMEtimes, calling a function would
create new variables for you, or reassign them, and sometimes it
wouldn't... ugh.  I don't like it.)

> Well. Sure it is. Damn, I think you're right. ;-)

Glad you see it that way =)

(Tuple unpacking is also brilliant, by the way, for constructs like
	for key,val in dict.items()
)

Subject: [Zope] efficient internal redirect
Message-ID: <38CCA329.9A3754CC@open.ac.uk>

I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

Not exactly. I suggest you read it again. What you and Martijn propose
gives _no_ type safety at run-time. That's just like using constants,
except they're wrapped in a module namespace.

And they do pollute the top-level -- that is, the module-global --
namespace. Let me know when you find out how to enumerate the values in
an enumerated type, and how to convert an enumerated value back to its
name -- and then I might think you're up to something.

Similarly to C++, Python classes behave like namespaces, so you can
avoid pollution by wrapping the values in a class:

	class Foo:
	  FOO, BAR, BAZ = range(3)

and so you can enumerate the values as attributes.

True. However, personally I prefer lexical scoping -- which I hear is
under consideration for Python 3000 -- to the weird three-level
namespace that Python provides. Having to import "global" variables
because the compiler optimizes assignments is way uncool.

I'm not contesting that dictionary keys should be immutable, but rather
that lists and tuples are nearly the same things (*nearly*, but not
quite) with the crucial difference that lists are mutable. Why? There's
no real design here. The only scientific answer to that question is
"Because."

Take a look at my Redirector product, which does this very thing -- it
lets you create Redirector folders which, when rendered, simply redirect
to somewhere else.

It uses regexps to let you apply patterns, such as saying that "/Parrot"
should redirect to "/PetShop" but than "/Parrot/Fish" should redirect to
"/Aquarium". It allows 1:1 redirects as well as many:1 redirects.

Dylan Jay has derived an improved version that supports simpler group
replacements using replace(). Both versions are on zope.org.

I agree with your points, but what is more important for me,
is that the rendered HTML is syntatically correct

* this is an item

* another item

* a third item

currently renders as :

<ul>
<li><p>this is an item</p>
<li><p>another item</p>
<li><p>a third item</p>
</ul>

which is not very slick.. I'd prefer a forward-compatible
list-rendering format, complying with HTML4.0 and XHTML,
looking like this :

<ul>
<li>this is an item</li>
<li>another item</li>
<li>a third item</li>
</ul>

Anybody who has tried to make Netscape4.x understand CSS
without properly closing tags will understand my point..

Thankyou for replying

Whilst this is I'm sure a useful mechanism redirecting
whole folders is overkill for what I need to do.  I have
many links into a tree and wish to have a very simple format
for the external links and an internal mapping mechanism
which maps each link to its real URL.  My question remains.
What's the most run-time-efficient (not development-time-efficient)
way of doing it?  I think you gave me the quickest development
route which is not quite what I was asking.

I agree with theese purposes on Structured Text...

I would like to be able to write simple tables with Structured Text.
Something like :

| FirstName | LastName | Age |
| Olivier | Deckmyn | 25 |
| Guido | Van Rossum | 32 |
| Linus | Torvald | 29 |

That will build a simple table :
<table>
  <tr>
    <td>FirstName</td><td>LastName</td><td>Age</td>
  </tr>
  <tr>
    <td>Olivier </td><td>Deckmyn</td><td>25</td>
  </tr>
  <tr>
    <td>Guido</td><td>Van Rossum</td><td>32</td>
  </tr>
  <tr>
    <td>Linus </td><td>Torvald </td><td>29</td>
  </tr>
</table>

Customization could be done with CSS...

Why can't they be the one and the same? Redirector is fast -- I suspect
the difference in speed between Redirector and something else would be
negigible.

Remember that a Redirector folder is in itself just an index (of
regexps -- it's not hard to wire the lookup so that, if the term is not
a regexp, then it will use a dictionary, which is a lot faster). It does
not need to contain anything, and you need only one Redirector folder to
accomplish what you ask for. Let's say you have three areas that others
link to: Downloads, Registration, and News. First, create a Redirector
folder called, say, /Targets. Then edit the folder's redirection
mappings to look like so:

	From                   To
	Downloads              /Downloads
	Registration           /Snark
      News                   /News

Notice that the Registration name maps to /Snark -- this to illustrate
the mappings have nothing to do with the *names*. Now, having done this,
you can access your mappings like so:

	http://www.myserver.com/Targets/Downloads

which will redirect to

	http://www.myserver.com/Downloads

Isn't this what you want?

Shouldn't that rather be

<ul>
<li><p>this is an item</p></li>
<li><p>another item</p></li>
<li><p>a third item</p></li>
</ul>

After all, we *are* talking about paragraphs here. I happen to like --

Subject: [Zope] getting port number into URL - was where port num gone
Message-ID: <38CCBEF7.BF8534E5@open.ac.uk>

I'm sorry to ask this again but there must be a way of
getting a port number into a url without being explicit
about the address.  There has to be because absolute_url()
does it inside a tree.  I just don't know what I can use
and the expression syntax to do so.

I have this

root
    ltscimages
        someimage
    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltscimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

Andy

.. not necessarily.. the <p>s imply a paragraph of text,
which is not necessarily what is contained in the <li>..

i agree that in most cases the visual result is better with
the <p>, but this should really be taken care of with css.
As far as possible, presentation and content should be
separated...

the <p>s would be ok with me, if we just got the <li>s to
close correctly, but i don't think they should be there if the
reason is purely aesthetic..

Imho closing the <li>s is all we need -- adding padding with CSS works
with the latest browsers, but we still have non-CSS browsers. As much as
I prefer pure, CSS-enriched HTML, it doesn't work all that well in "real
life". Not yet, anyway.

I confess, what you have is a very good idea.  The reason I'm hesitating
is because there won't be two or three areas and its wrong to call
them areas.  They will be single documents and a little bit further down
the
road there may be hundreds of them needed and not in any homogenous
flat structure but at different places in a tree.  Also,
I really do need every last inch of speed out of this part.

Hardwiring your code to use a dictionary looks like a good idea for
the present.

Some questions:

1. does your product redirect back to the client or within zope?

2. assuming it were hardwired as you suggest what would be the runtime
cost over just having folder methods in zope do the redirection?

3. I haven't touched python for 2 years now (though I did use it a lot
then) - I'm very rusty.  Could you supply a patch to hardwire in a
dictionary
instead of the regex code?  Assuming 2. is satis this *could* be a good
answer.

4. still looking for an answer to my orginal q - what's the most
efficient way?

One of myw own - words in single quotes 'like this' should NOT be turned
into code examples.  Most people do not write code examples in their texts.

Or add the whole special_formats dictionary available in PythonMethods to _.

In general, strucutred text needs a complete rewrite to make it extendable
and customizable.  Using the current structure you end up commenting stuff
out and rewriting sections of the code, which is not a very good way of
working.  But I doubt DC have the time for that.

Why not derive a specialized version of my product ("Redirector Method")
that descends from not Folder, but SimpleItem? If each such method
represents only a single "mapping", you get what you ask for.

Of course, if you have plugged your Zope into Apache, then it would be
more efficient to use mod_rewrite anyway.

> Some questions:
>
> 1. does your product redirect back to the client or within zope?

Yes. It forces an HTTP redirect. I don't if Zope is re-entrant; that is,
whether you can emulate symbolic links by passing the request, modified,
back into Zope.

> 2. assuming it were hardwired as you suggest what would be the runtime
> cost over just having folder methods in zope do the redirection?

Not sure if the word "hardwired" is correct here. After all, what I just
described to you in the previous email was not about changing the
product itself -- that's hardwiring -- but changing the parameters to
the product's *folder instance* -- that's Zope. ;-)

What I suggested about using a dict for non-regexp mappings does not
involve any hardwiring, either -- I meant patching the product to
support dicts *in addition* to the existing regexps. Basically in the
folder's management interface you'd simply specify whether a mapping
used a regexp or not.

Runtime cost: You would have to time it. Marginal, unless you're
expecting a gazillion hits.

Let me think about it. I'm pretty busy -- perhaps Dylan is up to the
task, he did the previous patch.

mod_rewrite.

You know, I have a similar problem... I have 6 aliased IP addresses. 
I'm running 3 zopes, at the moment.  All of them have been told what IP
address to use.  The first can listen to 8099 and 8021 no problem, but
the rest of them complain.

if I do -f '' and -m '' everything is fine, but they're all listening to
8080, so what's the gig?

netstat shows localhost:8099 and *:8021, and the same for the other
server that I set to 9023 and 9023 respectively.

Does Zserver listen indiscriminately on ftp and monitor?

But still people do change compilers! People have added garbage collecting
to the Python interpreter, list comprehensions, and there's the whole huge
stackless effort. I'm sure there are more examples in the past, for Python.
Without open source, this wouldn't have happened.

I've thought about it too, and no time either. Maybe we should get

That's indeed a shortcoming in Zope as it stands, but that's not an

That's true, but please note that C's enum is used successfully and

I agree it might be nice to have a more elegant way to deal with
enumerated types. Perhaps as a result of static type checking extensions?

Well, it makes sense to disallow mutable dictionary keys. You asked why
have two kinds of lists, I tried to give the answer. Lists and tuples have
been moving towards each other in recent Python versions, though; I believe
originally only tuples supported unpacking. If there was somekind of
mutability system in place that could replace tuples.

It's cute though, as immutable objects behave like pass by value objects
do (except those darn tuples again, if they contain something mutable like
a list or an instance). I think that's a neat idea.

Python has a syntax for that:

You have misunderstood what I'm asking completely (probably my fault).
I am using apache and zope, some pages served via the zope-->apache
route, some
directly from Zserver (faster than going via apache) and some just with
apache. Some addresses are already being rewritten by apache - that's
not
a problem.  The mechanism I am seeking to use is just something like

<dtml-var destinationPage>.

Since this doesn't go back to the client between it has to be faster
than going back to the client and doing another request for these
particular
pages (which are in this database anyway).

Please can people reply to my original post without recommending
the redirector product.  I've reproduced the post below in the hope
someone can answer it for me.  Please don't reply telling me how
marvellous the redirector is - yes its a good idea but its not
what I'm looking for here - I'm just looking for some help to
know what's the fastest method and how to code it.

Original post
-------------
I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

[snip]
> You have misunderstood what I'm asking completely (probably my fault).

If I were you, I'd definitely go over that original post of yours again
and consider how it can be rephrased -- because from what you say, this
is how I see your problem:

1) Pages within Zope
2) External sites or pages that link to these pages
3) You'd like the underlying pages to be separate from the URLs to which
these external pages refer, so that you can move the actual data around.
4) You want this to perform really well.

From this specification, it sounds like, aside from the marginal
performance loss incurred, you should be able to make do by using plain
old HTTP redirection. Did I get any part wrong?

You could use a kind of hub method like so:

<dtml-let Mappings="{
  'Downloads': PARENTS[-1].Downloads,
  'Foo': PARENTS[-1].Bar,
  'Snarf': PARENTS[-1].Smurf.Snark
}">
  <dtml-var "Mappings[REQUEST.Where]">
</dtml-let>

Assuming the method is called /Hub, then you can invoke it like so:

	http://www.andysserver.com/Hub?Where=Snarf

and it will display, in this case, the object "Snarf" in the root-level
"Smurf" container. While this works (you can also use a TinyTable
instead of a dictionary), this has a few gotchas, such as causing
trouble with proxy roles. No HTTP redirects, but not as elegant.

Oh, and did I mention how absolutely marvellous the Redirector product
is? ;-)

Subject: [Zope] manage_delObjects problem
Message-ID: <3.0.1.32.20000313085541.0068c54c@bizux.net>

Can anyone give me any insight as to why the below URL doesn't work.

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?id=8185

After the URL is visited the manage screen comes up and tells me "No Items
were specified!" 

So I am a little confused as to why there is no item specified, when I am
sending the 'id' number with the URL, and will the activation of this
hyperlink take me to the manage screen or just delete the object and leave
the user at the page where the hyperlink was requested from.

Best regards, 

-M.

Yes.
Plain old inclusion (like #include in C) would work faster
because it doesn't go back to the client in the same sense
as HTTP redirection.

There is some way of doing this in dtml, I know because
I had something working at one point but I can't remember
what it is.  I do remember it only worked if the objects
that were redirected to (equivalent of included) were methods
not documents.


<dtml-var "whatever.whateverelse.object> gets the right object
but it doesn't get rendered.

This will imply some parameter to define whether you want headers or not
as not everybody uses them. Unless we can come up with some clever (but
visually pleasing in ASCII) format. 

Alexander also mentioned he does not like the <p> elements inside <li>
elements but IMO are required in cases where there are more than one
paragraphs in an <li> element. Unless we default single paragraphs in <li>
elements to non <p>, but then we break consistency.

I suppose a complete rewrite of stx is in order using a more modular
interface. For example I was thinking of one class per structure element
with the appropriate input method to receive the stx text, and a number of
output methods to produce a variety of formats, html,pdf,rtf etc. This is
the approach I followed in the Table patch but it is also slower. The
original stx was designed with performance in mind.

One suggestion I have (and it would be relatively easy to implement) is to
cache the rendered document in a volatile attribute attached to the
DTMLmethod/Document that contains it, together with a simple checksum of
the input text. Then we would be free from the performance constrain at
least to some extent.

Hi,

I have the following access rule:

<dtml-if "_.has_key('virtual_host') and REQUEST.environ['HTTP_HOST']==virtual_host">
 <dtml-call "REQUEST.setURL(path='/')">

The idea being that if a folder represents a virtual host (see the thread 'REQUEST vraible methods'
on this list for background...) you can just give that folder a virtual_host property which the
above rule checks for, and if it matches that in the header, if sets the base path to '/'.

However, if I try and access any folder with this rule in it, I get challenged for authentication
and get 'Authorization failed' no matter what username and password I use, including the root ones!

What is going on?

Would using re (so it can take advantage of multithreading) make up for a
more complicated rendering engine?

This wouldn't work in all cases - consider <dtml-var ZopeTime>, where the
output changes every time it's called.  If an object contains only
strucutred text then you store the rendered text too, and update it every
time the input text changes - the PTK has an object that does this.

manage_delObjects expects 'ids' - which is a list - as parameter. So,
try

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?ids=8185

or:

No, the user will be directed to the management screen. To prevent this,
you can either create a dtml method or you put something like:

<dtml-if delobject>
  <dtml-call "manage_delObjects(delobject)">
</dtml-if>

into the calling page and change the link to:

Hmm I hear the new re module of python1.6 is fast .. so a migration to re

If a block of structured text contains dynamic content then you are right,
caching won't work, but in many cases structured text documents contain
only static text. It does not harm to cache unless you have many stx docs
and little memory. I haven't checked PTK yet but in Zpdf Document the
rendered output is cached in a volatile attribute together with a fast
checksum on the input text. Works quite well and ZODB takes care of
garbage collection during object deactivation.

Hi,

I am new to Zope, and having some trouble.  I imported my directory
structure into zope, but zope doesn't recognize server side includes...for
example, 

<!--#set var="TITLE" value="Some title here"-->

I get the error: Unexpected tag, for tag ......

Is there a way to get zope to recognize server side includes?

Thanks,
Jessica

Referring to server side includes, I probably should have put that this
line was an error as well: 

<!--#include virtual="/include/header.html" -->

Subject: [Zope] mange_changeProperities external method
Message-ID: <3.0.1.32.20000313105947.0068de3c@bizux.net>

I have an a form in which the user can edit an instance of a ZClass and
resubmit the data. This data is to be used instead of the data that is
currently listed within the properties of said object.

After submitting the change I get this error:

Error Type: AttributeError
Error Value: 'string' object has no attribute '_properties'

The code that it is referring to is:

def editTaskProperty(self,REQUEST,RESPONSE):
  taskobject = self.taskstorage.REQUEST['task_id']

  for p in taskobject._properties:
    taskobject._setPropValue(p['task_title'], REQUEST['title'])

Can anyone give me any insight as to how the proper method of changing the
properties listed on an instance without the user catching any wind of the
management interface?

Best regards, 

Mark

You can do it in a DTML Method (very similar in an external method too)
like:

<dtml-call 
"MyZclassInstance.propertysheets.Mypropertysheet.manage_changeProperties(REQUEST)">

The reason I was using the external method was to avoid the user from

This should work, is 'The Right Thing'.

If you are using a DTML Method, then it will be a method *of the
folder* containing the method. DTML method's dont add a namespace of
their own, so <dtml-var title_or_id> is supposed to give you the
folder's title.

No.

I mean that setting a production flag on the zope server and let all error
messages goes silent.

It will be very difficult and troublesome to keep track of all errors. Just
because some one have make a rename on one of my object, or the object is
being modify and thus not available.

Also, are there anyway to remove all the manage things from a production
site?

Are you killing the server between restarts, or closing it politely
with the management interface? The polite shutdown writes an index
file that speeds up the restart.

My development database has 30k objects, and restarts in under 3
seconds.

The call Pavlos gave does not visibly expose the user to the
management interface.  It does assume that the variables to be
changed were supplied in a form that caused this method to be
called, but that can be your own tailored form.  Or if you get
the values some other way, you should be able to pass them as
args to the call.

there are a few of howtos in Zope which use structure text were broken. I
dont remember all of them, but the one with date and sql is (I still can not
read it).

BTW, I  think structure text should be not be used in current way.  I think
a good use of structure text is to use it convert from/to. Instead of
publish.

A greate tool but in bad use.

But what would that look like?  The task requested by the user can't
be completed, so they need to get *some* sort of error message.  Or is
it that you are running with -D and so getting the python tracebacks
in the error web pages and you want to eliminate those?  In that
case, just remove the -D from your start script.

No, but anonymous users can't (by default) access the management
screens.  If your visitors have userids, just don't give them
permission to access the management interface, and they'll never
see it.

If it's a DTML Method, you could do <dtml-var
"whatever.whateverelse.object(_.None, _)">

There is also a _.render method that I've never had occasion to use.

Also, if you want to make things a bit more generic and work somewhat like
the Redirector, you could also do a
<dtml-var "REQUEST.resolve_url(the_new_complete_url)(_.None, _)">

All untested, but will hopefully help you along...

Hi,

I have the following python Class in MyTest module:

import DocumentTemplate

class Test:
	index_html = DocumentTemplate.HTMLFile('test_form.dtml')
	
	def __init__(self):
		... 

	...

	def mymethod(self):
		return 'Hello'

In my DoTest.py module i have:
import MyTest
t=MyTest.Test()


If I run:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t

i get the correct output (a html file with http header).

but if I try:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t/mythod

i get the following error message:
***************************
Status: 404 Not Found

...

  <H2>Zope Error</H2>
  <P>Zope has encountered an error while publishing this resource.

<!--

I really don't know what is my mistake. I'm pretty sure that mymethod is a
method of the Test class. I can also access to the variable index_html of the
Test class, so why am I unable to access Test instance methods this way?

Actually, I also tried the example in the Zen HowTo: The (old) Product API
Tutorial. Is there now another way to call a python class instance method
with the debugger?

If I do the <image src=imagename explicitly I have to fill

Thanks for this. Only just got round to trying it. For dummies
like me does "re-build" means do "python wo_pcgi.py" again
from the root of your Zope install (under Linux)? (Having,
of course, replaced the lib/python/ZODB/TimeStamp.c file.)

I hope so because I just did it and it seems to have solved
the problem in as much as new News Items in my PTK-generated
pages no longer all have dates of 29 Feb. (I guess there may
be more finely honed ways of just causing a selective
re-build ....)


I note, however, that those News Items that were created with wrong 
dates, still have wrong dates (at least as displayed on 
the Web pages). Perhaps this is a problem that is just
local to the PTK?

Yeah, I knew that, but I love the fact that everything in python is really
just assignment, so I do it explicitly a lot.  I got carried away... :-)

Your method does not have a doc string.  ZPublisher will not call a
method unless it has a doc string.

The FTP handler does not accept a hostname argument in it's
constructor.  This is probably an artifact of the medusa code. 
Shouldn't be a hard fix.

The monitor server is hardwired to localhost.  I believe this was a
security decision.  You can hack z2.py any way you like to remedy it.

Nope.  Zope does not speak SSI.  It speaks a very similarly looking
language called DTML.  DTMLs 'old' syntax _looks_ like SSI, but it is
not.  It is syntactically different in many cases, and does not support
neccesarily same kinds of tags.

I sugest you read the Document Template Markup Language Users Guide on
the zope site.  It's in the Documentation section.

Subject: [Zope] condional client-side code
Message-ID: <38CD3812.64591827@open.ac.uk>

Ideas please - how to do this.

I'm using zope in frames and need some output to be
condionally there depending on what the window name
is.  The idea is  for client-side code to decide 
whether or not its displaying in a frame and output
a header if needed.

The only way I know to do this is with javascript

"if (window.name=="whatever")" etc.
on the client side.  What makes is messy
is having to hand-process the stuff that's on the
"then" part to put it in document.write() calls.

This is quite messy because there's quotes and all sorts in
it.  It would be nice to write

    document.write("<dtml-var whatever>")

but because of messy chars and returns and so in
in the "whatever" document it doesn't work.  Also,
its really desirable to be able to have "whatever"
in just one place and use it in different ways in
different documents.

My current thinking is - "is there some way I could
process the contents on "whatever" on the fly so that
it would work with document.write?

Any other ways to do what I want?

I believe error code 11 is a segfault, pointing toward a memory
problem.  I just finished dealing with a situation where zserver
was restarting, and increasing the available memory for the
process circumvented the problem.  This may well not be your
problem, but it may be worth looking at.

Is Zope supposed to handle out-of-memory problems gracefully?

For images, you can use:

<dtml-var "imagename.tag(border='0')">

I'm not sure what a "general method" would apply to, but I'd hazard
to guess that any object that produces a tag when rendered should
probably have a similar tag method...

Does Zope leave a core file?  Try 'find -name core -print' from the top
level directory.

Subject: [Zope] Enhydra anyone?
Message-ID: <20000313201057.94590.qmail@hotmail.com>

Hi,

Is there any comparison between Enhydra (Java-based open-source
application server) and Zope (Python-base open-source application
server)?

I guess Zope and Enhydra are colliding head-on. :) Can anyone
give a little bit more background to Enhydra?

Zope site used to have a page about comparisons (like with
PHP), now I cannot find that page.

Having worked with Java (and previously with C++), I must say
that I don't have a positive opinion about Java. I know Enhydra
has this "open source" thingy and even tries its best at painting
"worldwide developer hall of fame" stuff, but it seems kind of
corny. I just don't think you can do open source well enough
with a language like Java which was designed by the corportate
and for the corporate.

It's not that Zope is excellent, it's not. But Python's CP4E
(computer programming for everyone) approach eventually will
make it longer lasting than anything else, (especially after
Python 2 comes out) and I just don't see how Java can
survive in the long run. As for Zope, I guess in the long
run it will need a major re-work, otherwise it will lost
the competitive edge.

Message-ID: <001b01bf8d2b$aaf24ee0$0201a8c0@iridium>

Here is my quick intro to Enydra and why I think it is interesting.

Enhydra (http://enhydra.org)
======

Licence : OpenSource.
Technologies : Java Servlets, XML DOM.

Java-based Enhydra has possibly the most interesting take. It uses
JavaServlets to provide content. You give it your HTML file, marked up with
some extra attribute tags :

<HEAD>
</HEAD>
<BODY>
  <P ID=Fred></P>  <!-- a Param tag with ID -->
  <P ID=Jim></P>     <!-- another -->
</BODY>

It then turns this HTML into a Java class with all the tagged elements given
getter/setter methods in the class. It compiles the class.

So now if I want to do something with the HTML fragment above I just create
an instance of MyClass and do things like :

  GetElementJim.SetText('My content for Para1');
  GetElementFred.SetText('My content for Para2');

In essence the Class models a XML DOM tree for the HTML put in so you can
now apply DOM methods to it to manipulate the model.

This neat because :

1. It's in compiled (well, as far as Java compiles) code so is quick.
2. DOMs  kick out "compressed" XML content, all redundant spaces CR/LF pairs
are removed.

Enyhdra also pools DB connections to improve performance.

Message-ID: <38cd5575.3a09.0@jps.net>

Hi Dave,

Unfortunately, I don't have an answer yet.  I am still trying to get the damn
thing to work.  I had ZMySQLDA working until I tried to run a query.  Then I
got the same error that I got when using MySQLdb.

Right now I am in the process of wiping everythin out (short of Linux itself)
and will try a re-install.  I hate doing this because I still don't understand
the source of the problem!

Anyway, I'll keep you updated...

Seems like this discussion should be moved to c.l.p., but ...

I don't understand your objection here. Tuples are immutable "by
design," or "by definition" if you prefer.

What alternative approach would you suggest?

We certainly benefit from having a mutable sequence type designed to
contain arbitrary objects.

We benefit from having a high level mapping type designed into the
language. You agree that dictionary keys must be immutable and you
appear to agree that sequences make useful keys, as well.

Under the covers, we also benefit from Python's design choice that
assignments create object references and the design choice that
dictionaries hash object references, not the objects themselves (which
therefore requires immutable keys).

So what's wrong with Guido setting things up this way and then saying,
"hmmm, this is pretty cool, we just need an immutable sequence type for
use in dictionary keys."

It's a little like the Old Testament Creation mythology. God creates the
heavens and the earth and he sees that it is good. But he decides he
needs to populate it. He finds that one human type isn't enough -- it
gets lonely. So it turns out that in His world, he needs two essentially
similar types, but with a key difference.

So Guido took a rib from the list and made the tuple.  ;)

For my own information, could you tell me how big big is?  I'm running a
database of 60K objects, and when there is a lot of activity on the 
database, the process grows to about 150M.  At around 180M, it
locked up and I had to restart Zope.  I think my server ran out of
available virtual memory.  (I'm moving the database to a dedicated
server Real Soon Now).

I use the attached script to batch-upload directories of jpegs as Photo

I found the source to String.__call__ (in DocumentTemplate/DT_String.py) very
enlightening. This is the same __call__ method that DTMLMethod and DTMLDocument
inherit.


    def __call__(self,client=None,mapping={},**kw):
        '''\
        Generate a document from a document template.

        The document will be generated by inserting values into the
        format string specified when the document template was
        created.  Values are inserted using standard python named
        string formats.

        The optional argument 'client' is used to specify a object
        containing values to be looked up.  Values will be looked up
        using getattr, so inheritence of values is supported.  Note
        that names beginning with '_' will not be looked up from the
        client.

        The optional argument, 'mapping' is used to specify a mapping
        object containing values to be inserted.

        Values to be inserted may also be specified using keyword
        arguments.

        Values will be inserted from one of several sources.  The
        sources, in the order in which they are consulted, are:

          o  Keyword arguments,

          o  The 'client' argument,

          o  The 'mapping' argument,

          o  The keyword arguments provided when the object was
             created, and

          o  The 'mapping' argument provided when the template was
             created.

        '''

You can see that __call__ with no arguments uses defaults of None and {} for
client and mapping, so essentially the template has nowhere to look up
attributes. This is why you must pass these explicitly. Apparently you can also
pass a mapping and keywords to the constructor but I don't think this is
possible from the management interface.

More ZZen is to be found in DocumentTemplate/DT_Util.py. This module contains
the expression evaluation machinery, as well as the code to the special
namespace variable, '_'.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A069@express.sematech.org>

I've put the following in a SQL method, but can't figure out where the count
ends up...

<dtml-in "_.string.split(tool_id)">

tool_id is a string (like 'EXP01 EXP02 EXP03').  For my normal DB activities I
use count-attribute name for the count total, but I can't seem to find out where
the count is stored in this example...  I tried getting the key with
sequence-key, which returned 1, but count-1 returns 0.

I've solved this already with
<dtml-if expr="_.len(_.string.split(tool_id)) > 1">

but this bothers me....  I know theres a better way!

Hmm, a simple test script seems to indicate that sending a child process
a signal 11 does not cause it to dump core.  Of course, it also does not
seem to cause it to return a status code of 11 either.  This might not
be a SIGSEGV, it might just be a coincidence that the return code of the
(crashed) child is 11.  (FYI, there are two processing going on here, a
'watcher' parent and a child, the parent prints the 'Aieee!' when the
child dies.

Does anyone out there know what a python program returning 11 means?

I think both NS and IE default to check for modified content 'only once per

I know that Zope has the capabality to keep up some sort of version
managament system for zope documents.  I have two questions concerning
this.  One, where might I find some more info concerning this.  And two,
what if I want to use my fav editor - say vi or pico...but that's another
war I don't want to start ;)...instead of the window that zope provides.
IF the file already exists in zope, and then I go and make changes in a
separate editor, and upload the file, since I am uploading the file, will
zope keep track of this as just another version of the same file?  Thanks.

I don't know where the docs are, but I just started using versions
so I can answer this.

In your top level folder, go to the 'add' box and select 'version'
from the items to add.  This will create an object in that folder.
click on the object, and you'll get some management tabs.  You can
'join the version', and you can save or discard changes.  Once you
have joined the version any changes you make will not be visible
to anyone who has not also joined the version.  (Making changes
to an object will lock out any other updates to that object from anyone
not in the version).  When you are satisified that your changes
are working, you 'save' the version, which makes them visible to
the rest of the world. 

Each change you make to an object is committed to the zodb in a 
transaction, by the way, so even without versions you can
go back and "undo" a change you have made using the undo management
tab.  I'm not quite sure about the rules that determine when
a transaction is burried deeply enough in the undo stack that you
have to undo things above it to get to it, but it is still a
very handy feature.

Someone is developing a ZopeEdit program that helps with this.  I haven't
looked at it yet.

Yes, the upload should appear in the undo stack.

Message-ID: <00031317565600.03374@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

I'm trying to make my own pyhton classes and use them with zope, so I tried to
subclass the class Persistent. However, no matter what I try I get always an
error like:
***
Bobo-Exception-Value:
(<class exceptions.ImportError at 80a9d98>, 
'cannot import name Persistent')
***

I have read "The (old) Product API Tutorial", "Create a Boring Product in
Python" and "ZODB" HowTos but I didn't find the exact way to do it. Even
reading the Persistence module doesn't enlighten me too much: it's just the
license and a string.

So I would appreciate if someone could give a clue about how to subclass
Persistent and to which module it belong?

Oscar

If you're trying to import your product into the interpreter, you have to load
the Zope framework first. The Zope initialization is where the Persistent module
is populated.

From $zopedir/lib/python:

import Zope
import Products.MyProduct
etc...

Access Rules are triggered before authentication can be performed, so their
permissions are nil.  If you want them to access anything other than REQUEST
(as you do) you must give them a Proxy role.

A lot of this is actually a question of terminology.  It is true that
Zope keeps previous revisions of objects around.  This is how you can
'undo' them.  However, this is somewhat unrelated to a Zope 'Version'. 
In the case of multiple revisions of an object, we call them revisions,
not versions.

A 'Version' is an object that you can join or leave.  When you join it,
you are given a 'private view' of your entire managment session.  Any
changes you make will not be shown on the 'public view'.  You can leave
a version and rejoin it.  You can commit a version or discard it.  That
pretty much sums it up.

You do not need to use Versions to get the benefit of previous revisions
and undo, Zope does this for you out of the box.

Your question about editors is related to all this.  You can
edit/add/delete object through HTTP using the managment interface, you
can also use HTTP POST and GET methods directly, WebDAV, or XML-RPC. 
All of these methods are based on HTTP (some editors work directly with
HTTP, or use a protocol transported over HTTP like WebDAV).  You can
also use FTP.  Any changes you make with any of these protocols will
cause a new revision of an object to be written, meaning that they can
all be 'undone'.

FTP however does not work with Zope 'Versions'.  You cannot use FTP to
upload information in a Version that you have joined because FTP has no
join/leave/commit/discard semantics.

Message-ID: <38CD82B7.66FDB982@exceptionalminds.com>

Hi,

I've been playing with WorldPilot on my little notebook PC running
RH6.1, and have noticed that when I access my WorldPilot folder, my
processor spikes and stays spiked until I kill my ZServer and restart.

My machine is just only a 233 w/64Mb RAM, but I have never seen Zope
behave this way with any other products. Running a top shows that my
python/ZServer processes are consuming far  more than their fair share
of cycles.

Has anyone else noticed this?

Thanks.

zopistas,

how would I write a dtml_method to render a objects history (undoable
transactions/revisions)?  any insight is much appreciated.  how about being
able to export the objects history (revisions) via XML and then I could pack
and then reimport it into ZODB (or is this complete madness? ) - this way I
can still pack and keep revisions around of specific objects... 

i.e. I would like to keep all objects revisions but need to PACK the DB
(because its overwhelming large) -- what is the way, masters de zope?

many thanks,

Message-ID: <38CD88EC.36D70F86@ep.newtimes.com>

After looking at both Zope and Enhydra I concluded for my purposes that
they really fit into two very different realms.  Both tools
(applications, application interfaces, whatever you want to call them)
fit the bill for developing web applications.  Both tools provide for
HTML/XML markup to easily integrate with web designers. 

Enhydra deviates from here to be more consultant/development driven with
its class file delivery/deployment method.  Where as Zope continues, it
provides an interactive management model, where the web designer can
update an application and extent it without having to have development
support, there is no compile phase that needs to be done before
deployment.

I believe it depends on what your perspective; If you're more
development centric, Enhydra works great.  If you have to interface
developers and designers on a an ongoing basis and want to deligate more
control to designers Zope is the winner.

Well thats my 2 cents.

Message-ID: <m3ya7ms7uo.fsf@wacko.pdx.net>

I've been reading through code trying to figure out what is going on
here, where this message might be coming from.  My current train of
thought is that the 11 exit code being seen is in z2.py is a result of
sys.ZServerExitCode getting set somewhere and z2.py exiting with that
code.

So I've been trying to find where code sets sys.ZServerExitCode and
what I've found is in ZServer.HTTPResponse.ChannelPipe.close.  In this
routine, the value of self._shutdown is assigned to r which then gets
assigned to sys.ZServerExitCode.  

It looks like self._shutdown only gets assigned when
ZServer.HTTPResponse.ChannelPipe.finish gets called and a response
header contains an bobo-exception-type of exceptions.SystemExit.

So I'm guessing now that somewhere this exception is getting set but I
can't seem to figure out why.

Am I completely off base here?

Subject: [Zope] Problems with dtml-in batch variables.
Message-ID: <00031412082101.01516@localhost.localdomain>

Greetings,

I am using the ever-so-handy next-sequence-* and previous-sequence-* variables
for a batched list.  This all seems to work fine, allowing users to look
through bite-sized portions of the list.

However, there seems to be a problem.  Whatever calculates these values appears
to assume that the numbers are sequential, which, in my case, they are not.

So, whilst i get the correct number of items each time, they overlap when they
shouldn't, and the next/previous limits are reported incorrectly.

The dtml-in tag in question is :

    <dtml-in "sqlQueryHere()" size=4 start=qs orphan=0>

Any comments?

Chris,

Are you saying that realmedia and netperceptions do their stuff
using Zope?  I've scanned their pages and can't find evidence
of that.  Or are you saying to go with a non-zope approach?
Seems like the non-zope way might be more expensive, for
a small site.

Hi,

Could anyone point me to any code snippets, which allows a user to add a
file attachment to a sendmail form.

I tryed the code in the user documentation, and the attachment is a .dat
file which contains the path name to the attached file?!?

I don't *think* there is canned solution to this in Zope, though
I haven't looked at any of the banner products yet.  But in
principle it is simple enough: the page that is responding to
the search query has access to all the search variables, so it
can decide which banner to include based on those keywords.  For
a simple banner list, dtml-if logic would be sufficient.  But
you probably really want it integrated with a complete banner
product.

In about two months I'm going to have to implement this for a
client.  I'm expecting to add it to one of the banner products
if they don't support it already by then <grin>.

I'm not sure what Chris meant, but it seems like you could do what Marc
wants pretty simply using ZCatalog. Just set up a catalog that indexes the
ads by keyword or title that matches the desired search. Then, when
presenting the search results, pick an appropriate ad from the Catalog...

No.  We just don't have a banner ad product that does targeting.

RealMedia does a very good job of targeting.  It's not (terribly) cheap,
but it does have lots of features.

NetPerceptions can help if you spend lots of time and $.  It's not a
banner ad system in itself, but a collaborative filtering engine that
you can produce recommendations with.  This can help in ad targeting. 
It's incredibly expensive.

And yes, I would say to go with a non-Zope approach right now unless
you're willing to put in the time to write an ad targeting and delivery
system yourself.  We'd love to see such a beast, but done properly its a
fairly complex and time-consuming undertaking.  We've chosen to
recommend off the shelf systems for a couple customers rather than
building our own so far.

Is there anyone else who has been having Zope crashes where SQL in related.  We

Subject: [Zope] User Role, Authentication, HTTP
Message-ID: <20000314035606.71539.qmail@hotmail.com>

Hi,

I have the following situation:

(1) I'd like to use Zope's security model, so I can prevent
    unauthorized users from accessing contents in subfolders.

(2) I want to keep user name and password in a database,
    not in acl_users folder. (Basically, I would like
    ZODB to be read-only. So I can't add users into acl_users,
    I have to add users into my own database.)

(3) I don't want to use the pop-up dialog box to enter the
    user name and password. I want to do it through HTTP
    form interface.

So, what can I do?

Is there a way in Python to tap into ZODB Authentication?
I mean, I could create a generic user for the purpose of
ZODB user authentication, and then activate the ZODB generic
user from the HTML authentication. Or is there a way to
add a role to the current AUTHENTICATED_USER, dynamically?
This problem seems common enough that people have probably
addressed it before.

Where can I find more information on manipulating Zope's
AUTHENTICATED_USER?

regards,

Hung Jung

Message-ID: <3.0.6.32.20000313212413.008ef100@pop.dnvr.uswest.net>

I have a few questions as to how to map zope objcts in python, and I'm
looking for help with this particular example.



I am trying to create a python method that will take one argument, a string
variable.  It will then find the people that match and return a list with
each of the person's data.



I have found two methods that come close to doing what I am after.  The
first one returns all of the people data, including all the variables, and
the second one filters out the people I don't want, but only returns the
ids.  I've tried switching aroung the map(None,self.ids) to
map(None,self.data) and I get typerrors from lambda.  

I don't fully understand how this is working or what the data looks like to
the interpreter, but I know I'm close

Can anyone help?



I've got ! these both work ! :

--------

    def peopleValues(self):
        """ return list of people's data  """
        return map(lambda x, p=self: x.__of__(p), self.data.map(self.ids))


    def remote_personlist(self, thisdjname):
        """ returns true with ids to remote people that match
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].meta_type == 'This Kind
of Person', rlist)
        rlist = filter(lambda x,p=self,s=thispersonname :
p.data[x].clientpersonname == s, rlist)
        return rlist

You're absolutely correct.  It doesn't appear to be in the documentation.  The
closest I could find was an offhand reference to 'sequence-length' in the ZQR. 
I just assumed that since 'previous-sequence-size' and 'next-sequence-size'
existed, sequence-size would also.

Did it, in fact, work?

Hmm... have you looked at the Generic User Folder Product?

I think it would solve your purpose. There is also a howto for

I don't think zope should crash if this happens -- but is there any time
when you'd be retrieving data that it wouldn't crash (insert name of your
favorite web browser here, it doesn't matter which one)?

Subject: [Zope] DTMLTemplate product 0.2.0 released
Message-ID: <200003140538.AAA03457@ml.media.mit.edu>

I've just released my first development version of DTMLTemplates.

You can find the distribution at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate

DTML Templates are documents that allow blocks of text to be named and
made available to other documents. The basic building block of
templates is the DTML "block" tag, which can also be used with other
DTML document types. Templates export their blocks. Another new tag,
the "suppress" tag, allows block definition without rendering.

Here are several nice features of blocks and templates that I believe
will greatly benefit the Zope community (several of these items have
come up recently in Zope email discussions):

	* defines libraries of methods in one file,

	* allows structured text formatting in a DTML document,

	* allows pieces of multiple documents to be combined,

	* allows complex web designs created with HTML editors 
          to be used as templates,

	* provides template elements that encourage proper
	  nesting of markup tags.

In short, I think that Templates offer great promise for the Zope
and Zope developers.

This release is a very early one, though.  A construct as fundamental
as this one may need both syntactic and structural tweaks to function
in the most useful way, and only with discussion can we figure that
way out.  Please don't count on this product being stable for at least
a couple of releases.  

I appreciate your interest and feedback.

This is a Zope crash, not a browser.  Zope dies with a NT exception.

I am currently adding this to my BannerClass foundation. I expect to
have this out in the next month or so. As to how well it will work, that
is up in the air at the moment.

<dtml-alert type=semi-vaporware>
"ZBanner System" (or whatever the final name will be) currently is
capable of hit/click tracking, verification of banner validity based
upon time (after, until, or during a date range), a set variable by
management, hitcount, and clickcount (I think that's all of them). It
also has preference capability (ad weighting).

It also supports ad style and type (where style is button, vertical
banner, and horizontal banner; and type is 'integrated', 'remote',
'local').  In the near future it will be able to call ads based upon
keywords passed to it.

So, why is this not yet fully available you ask? The feature I haven't
mentioned yet. Database independance. Basically, I want to get it set up
to where you can store your banners in the ZODB, and RDBMS, localfs,
whatever. So far, I have a good foundation, but need to pin down the API
better. WHen it comes out, I want to include an example implementation
or two. As soon as my test ZServer works properly again, I'll be able to
progress faster.

Wow, wow wow. :) Thank you very much. I'll try it out!
Seems exactly what I want.

It's funny, I have seen quite a few postings mentioning
about GUF and Generic User Folder before, (never understood
what it was, though,) and I even mentioned in my own message
that I wanted to create a "Generic User." But somehow I just
never made the connection. :)

Subject: [Zope] XXX-PythonMethods caveats?
Message-ID: <v04220800b4f3a7c28944@[128.240.198.13]>

Hi all,
I'm using Evan Simpsons' XXX-PythonMethods with great results (after 
a few false starts due to my ignorance!). However, in Guarded.py we 
have the following;

# BEWARE OF THE LEOPARD!

# Set 'do_XXX' true to allow creation of XXXPythonMethods
# and ADD A MASSIVE GAPING SECURITY HOLE to Zope.
# DON'T DO THIS unless you use secure connections for ALL OF
# YOUR ADMINISTRATION or are RECKLESS and/or FEARLESS.
# Even if you DON'T create ANY XXXPythonMethods, just turning this
# on will PUT YOU AT RISK BIGTIME!

Of course, I then set
do_XXX=1   :)

I only ever run my Zope servers under a non-priviledged account.

Can anyone explain what sort of leopards I should look out for, as I 
can see that I'd want to use XXX-PythonMethods for a lot more things.

Tone
ps the icon for the XXX-PythonMethod object is way cool! :)

Subject: [Zope] httpd.conf HELP! please
Message-ID: <Pine.LNX.4.10.10003140058240.20645-100000@hal.rescomp.berkeley.edu>

Good evening. We are a student group here at University of California,
Berkeley, and for the past couple of months we have been trying
(unsuccessfully) to get Zope to work with Apache properly. (We are
Residential Computing, a group which provides connectivity and support to
the residence halls at the UC Berkeley.)

The situation is as follows:

Right now, apache has been configured to pass all requests to zope.cgi
except for our personal pages (/about/staff), which a rewrite rule is
directing to a static file system location.

Our problem lies in an internal section of our site. We call it
/internal/.

What we are having problems with is getting Apache to authenticate the
user BEFORE it redirects to /internal/ in Zope. The other snag: everything
under /internal/ is under SSL. One area where we are not certain is if the
require user authentication specs should be in LOCATION tags or DIRECTORY
tags.

In addition to advice, if you have a similar set-up we would really
appreciate a snap-shot of your httpd.conf.

I have included snippits of out httpd.conf file below.

Thanks for your help,
Sachin

I'm seeing that on a box running BSDI.  I haven't looked closely
enough to see what time it is logging, but it certainly doesn't
*claim* to be GMT (it's giving -4 for the offset, which is wrong
and does not relate in any way to either the real GMT offset (-5)

I would like to open discussion on Version access over FTP. Few weeks
ago I have posted some suggestion on this to Jim Fulton, but no
reaction. I know he is very busy and so maybe here I get any
response. Below, plaese see copy of what I have posted to Jim.

Hi Jim,
I have a problem with versions with FTP. I already read your comment in
mail-list and also made little of traffic on the Zope and Zope-dev
mail-lists. After this, maybe I have a suggestion how to solve the
versioning also over FTP and not only HTTP. This problem arised for me,
when I tried to work with versions edditing my DTML code in Emacs.
        I suggest to be version object a container object. The access to
the version over FTP could be determined in URL. (The ID of version
object, to which I want to make changes, must be a part of
URL. Additioanaly, commands for join/leave, commit .. should be also in
URL, just after the ID version.) This mechanism could allow to work with
versions also over FTP. The classical version management over web
interface in collaboratin with cookies will not be changed, the
mechanism to work with versions also over FTP will be an addition. In
addition, in this way, the other people could see the version
('functionality of version') also over HTTP if they know the version ID
and put it in the URL.
        What do you think about this? If there is any other possibility
to solve my problem, could you inform me? 

Thanks in advance,



Could anybody response to this, please.

Evan,

Cheers, gave an anonymous proxy role, worked a treat :-)

I did notice while playing around with this that moving or copying DTML methods that have been set
as site access rules did have some bizarre effects I wasn't expecting. I think when I copied one, it
stopped working, or something like that...as well as some other such wierdities, is this to be
expected?

Chris

PS: What do you, or anyone else for that matter, think of the rule as a solution to the problem in
my earlier post? I don't *think* I need any magic folders or anything else, but I'd like to get a
second (third, fourth and possibly fifth ;-) opinion before I put it into production...

<dtml-if "_.has_key('virtual_host') and REQUEST.environ['HTTP_HOST']==virtual_host">
 <dtml-call "REQUEST.setURL(path='/')">

   I'd more interested in fixing fast reload problem. There were some
reports in the list, that after installing SiteAccess Zope sometimes hangs
for a few seconds when you press Reload (in browser) a few times. I can
confirm this behaviour, but I've never realized the problem is in
SiteAccess - I never ran Zope without SiteAccess :)

Hello,


there used to be a way to change the base classes for a ZClass. It's 
documented here:

<http://lists.zope.org/pipermail/zope-dev/1999-August/001288.html>

I haven't used it recently. It worked for me several time in Zope 2.1.1.

Make sure you backup your database before trying it.

Salut Olivier,


Did you solve your issue below? If not, please reexplain what you are 
trying to achieve.

If you want to render one of your ZClass with <dtml-var myClass> you may 
need to subclass "Renderable BaseClass" (available on the Zope site).

Or I am barking up the wrong tree?

It would appear that a Site Root and a Site Access Rule containing the following are NOT the same:
<dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

as my site access rule didn't work :( (it left the URL, BASEx and absolute_url() unchanged)

The only way I could solve it was to do the following:

Site Access Rule:
<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

And then put an empty SiteRoot object in the folder of each virtually hosted site.

Why did I need to do this? (more out of curiosity than anything else...)
Also why do the SiteRoot objects have to be in the folder of the virtually hosted site? why can't I
just have one in the root folder which gets picked up through aquisition (they're all blank anyway
;-)

And, most importantly of all, why does adding a site access rule prevent FTP access to Zope?

Subject: [Zope] SiteAccess breaks FTP!
Message-ID: <38CE382B.E4088A9E@nipltd.com>

Hi,

I'm trying to sort out the relative URLs of some virtually hosted Zope sites.
In a nutshell, there some sites visible to the outside world as www.site1.com, www.site2.com, etc
These are in /site1, /site2, etc folders off Zope's root.
The redirection is done using Apache's Proxy method, but I need to sort out BASE, URL, and
absolute_url() type things, which I'm doing using the following Site Access Rule:

<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

and blank SiteRoot objects in /site1, /site2, etc.

The only problem is that since I did this, I get the following whenever I try to FTP into Zope
(which used to work fine and which we use quite heavily for content editing with Dreamweaver):

 550 Could not list directory.

Why do I get this? How do I stop it happening? (preferably without stopping using SiteAccess...)

If anyone has any experience with this, I'd appreciate the help...

Chris

Mourning...

I've been trying to compile DCOracle for 8i under Linux and
I'm _really_ not cut out for messing about with C libraries.
I know Anthony Baxter has done it, but I have a strange feeling
he's probably not near a computer right now.

Has anyone else got this working?
If so could you send me your Setup file? (Better yet would be
to get it added to the ones already in the DCOracle package.)

Thanks for your time,

Chris,


I had exactly the same problem as you.

I eventually found it was a bad idea to use the precompiled python version
shipped with the binary package. In fact when I do :

$ python
>>> import _mysql

it works. However, when I do :

$ $ZOPEHOME/bin/python
>>> import _mysql

It doesn't.


So, I think the best thing to do is to bypass the binary python shipped with
the tarball. I'm dowloading the source version to check if it is ok.

I can't get this to work at all:
<dtml-if "sequence-size > 1">
zope complains about not being able to find 'sequence'.  I had solved this issue
before with a let tag <dtml-let size=sequence-size>, but it seems very wasteful
and adds a lot of syntax overhead to the code.  How can I access the sequence
variable in an expression?

Actually, I'm checking to see if I've got multiple elements.  If I do, then I
use IN () in my DB query, else I put in =.  When I split the string, I don't
know if I have multiple items.

Access Rules are designated by name within their container; If you rename
them, copy them, or move them, the new/renamed method will not be a Rule
unless you designate it as one.

Looks good! This is similar to the solution that Digital Creations came up
with, and is better, I think, than my SiteRoot behavior.

> It would appear that a Site Root and a Site Access Rule containing the

> <dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

Was this Rule living in the subfolder where the SiteRoot would have been?

Location determines the point at which the SiteRoot affects the URLs.  If
they did their internal 'setURL' in the root, all that would allow is
replacing the initial '/' with the path of your choice, when what you want
is to replace '/foo' (or whatever) with '/'.  A variant of the SiteRoot
scheme in which you could say "replace /foo with /" in the root would
require either rewriting the URLn/BASEn and absolute_url code to include the
replacement, or a hook after traversal completes which allowed the
replacement to be done before rendering the final object.  Either would
work.

> And, most importantly of all, why does adding a site access rule prevent
FTP access to Zope?

This is news to me! Prevents how?  What are the symptoms, and does it matter
what the Rule does?

So you've confirmed this behavior, and it goes away if you remove
SiteAccess?  Does it matter whether you're using an Access Rule or SiteRoot,
or is having the package installed enough to cause the problem?

[Sorry, I pressed the wrong key with my last message ; so here it is :]
Thanx Alex !

I've been fighting a little with the URL, but I got it  :)

For thoose who would have difficulties (like I've had!) here is the source
(should be zc.py) :

#!/dev/null
#
# (c) 1999 M.T.G. Handelsges.m.b.H.
#
# This module is only an experimental Extension module to play around with
ZClass internals.
#

import string

def fetchzclass(REQUEST,prefix=""):
    rg=REQUEST.get
    PARENTS=rg("PARENTS")
    product=rg(prefix+"product")
    zclass=rg(prefix+"zclass")
    app=PARENTS[-1]
    prod=getattr(app.Control_Panel.Products,product)
    zc=getattr(prod,zclass)
    return zc

def strbases(zc):
    r=[]
    for i in zc._zbases:
 r.append(str(i))
    return string.join(r,"\n")

def show(self,REQUEST):
    "This shows the bases of zclass in product."
    zc=fetchzclass(REQUEST)
    return strbases(zc)

def copybases(self,REQUEST):
    "this copies the bases from class srczclass in srcproduct to dstzclass
in dstproduct."
    src_class=fetchzclass(REQUEST,"src")
    dst_class=fetchzclass(REQUEST,"dst")
    dst_class._setBasesHoldOnToYourButts(src_class._zbases[1:])
    rg=REQUEST.get
    get_transaction().note("Copied baseclasses from %s[%s] to %s[%s]." %
      (rg("srcproduct"),rg("srczclass"),rg("dstproduct"),rg("dstzclass")))
    return strbases(dst_class)

Here is the doc (still from Andreas Kostyrka andreas@mtg.co.at):

Well, install the attached zc.py in your Externals directory. Add
external methods zc_copybases and zc_show (mapped to zc.py/copybases
and zc.py/show) somewhere in your ZOPE. For demonstration I assume
it's in your root folder, and your zope server is called
http://myzope/.

Well, then use your browser to visit the following URLs (this does
more or less exactly what the above python magic does):

http://myzope/zc_show?zclass=YourZClass&product=YourProduct
http://myzope/zc_show?zclass=TempZClass&product=YourProduct

   This shows you the baseclasses of the two Z classes.

http://myzope/zc_copybases?
srczclass=TempZClass&srcproduct=YourProduct&
dstzclass=YourZClass&dstproduct=YourProduct

   (This should be a one line URL.)
   This does the voodoo magic above. And completly without shutting down
your ZOPE, and
   it does even comment the transaction nicely. (Interesting question if it
is undoable.)

And yes, the attached file is twice unsupported ;)
1.) The voodoo is not supported by Digital Creations, so it may change
    at any time.
2.) The external module is not supported by MTG, as its voodoo coefficient
    is to high.

but...this is not exactly what I want :

I have two (or more) rendering methods ...
Sometimes I call one or another, depending on the page I want to render it
in...

I wanted to write :
<dtml-var myClass.render_1>
or <dtml-var "myClass.render_1()">


but never works :(
The only thing I've found to be working is :
<dtml-with myClass>
  <dtml-var render_1>
</dtml-with>

pas glop...

So, it's okay to copy a Site Access Rule DTML method to another folder and then set as a Site Access
rule in that folder? I could have sworn when I tried it, the original stopped working too...
...but I was probbably wrong...

Nope... I was hoping just to have one Site Root Access rule that got aquired for each site. Is that
not possible? :S

Evan,

I don't think it matters what the rule does, it's just enough to have one set. It does, however,
matter where it is. I had to remove the site rule in the root folder so people could get on with
their work, but I left one in one of the virtually hosted sites.

FTP access now works fine except in the folder with the Access Rule in it. That said, that folder is
a Squishdot site and so I don't think it was accessible from FTP anyway...

Hope this information helps :-)

Hello,

I am new to Zope, so this might be a FAQ, but my seraches of the Zope

I am using a Z Class with Property Sheets to define the fields for each of

Since python interprets "sequence-size" to be sequence minus size, you need
to do a namespace lookup to get at the value.

<dtml-if "_['sequence-size'] > 1">

will do the trick.

Corel is more of a desktop version, so I'd say not, while Debian has a Zope
package so it's very easy to install and upgrade.  But I personally use
Redhat (and will install Debian 2.2 when it's released.  And OpenBSD when I
get my CD...).  Truth is that it doesn't matter.  Especially if all you're
running is Zope.  If you're running Oracle or some other commercial software
you'd want a commercial distrib such RedHat or SuSE.

Not really.  Just use whatever you're comfortable with.

Nice to know the trick, though.  Now I just need to find where the sequence-size
is stored as....

This is almost a religous subject but here's my two cents

it depends on your experience and what you want to do.

i've run Zope on Suse6.3, redhat6.1 and mandrake7.0
the differences between redhat and mandrake for a server are pretty
minimal, basically the pentium tuning in mandrakes rpms which are
meaningless in the context of installing zope and python. so for the
purpose of this discussion i'll call them both redhat. 

for automating startup of zope:
i personally found suse6.3 rc scripts to be alot easier to figure out
they have skeleton in /etc/rc.d/ which you copy alter and symlink into
the /etc/rc.d/"runlevel" directories you want to start and stop zope in.

try man init.d (in Suse)

for playing around with experimental stuff:
i would def. have to say go with redhat. if you want to play with stuff
like ZopeStudio(interface into Mozilla). Suse6.3 comes with a lot of
stuff in RPMs on CDs but requires a bit more experience to get stuff
installed from source and most sites don't offer suse RPMs which
generally aren't compatible with redhat RPMs. Suse itself doesn't offer
updates on most of its RPMs unless they're bugfixes for major programs.

 
for locking the box down:
i would go with Suse6.3. a good sys admin could lock either down. it
really depends on your experience from a sysadmin level. suse6.3 has a
pretty nice hardening script that passes SAINT with flying colors.
Bastille Linux is basically a redhat hardening script but i haven't
played with it at all and it tends to lag slightly behind the latest
version of redhat. 

for a minimal install:
i would go with Redhat.

my choice: Suse, but thats my personal bias cause i think its a better
distro. 

as for the other distros: the only other one i would consider seriously
is Debian, cause it has a very nice package management system through
which keeping your system updated is easy.

in summary: i really don't think it makes a difference, just go with
what you know.

This is untested but it should do the trick:)

<dtml-if "_.int(sequence-size) > 1">

as to why this doesn't work 

> <dtml-if "_['sequence-size'] > 1">
>Error, exceptions.KeyError: sequence-size 

i'm on shaky ground but here i think that your trying to lookup
sequence-size in the namespace variable but the batch process variables
aren't really defined in the global namespace.

This gives a key error as well.  To summarize what I'm trying to do:

<dtml-in "_.string.split(string_with_1_or_more_words)">
  <dtml-if "we_have_>_1_items">
   we have <dtml-var what_is_this_var?> items
  <dtml-else>
   we have only 1 item
  </dtml-if>

I can do the > 1 check with <dtml-if "_.len(_.string.split(string)) > 1">, but
it seems I should be able to get to a count-nnn var inside.  Since I'm not using
a SQL statement, I don't know what the variable is named.  sequence-size give a
name error wherever I use it (from the test screen of a SQL query).  <dtml-var
sequence-key> returns the fist digit of the word.

So, the question is, in the statement:

Howdy sports fans.  If the San Francisco traffic doesn't double cross
me, I'll be speaking at the Bay Area Linux User's Group meeting next
Tue, Mar 21.  The complication arises because I'm speaking down in San
Jose at SDWest from 5PM-6PM, then have to hurry back to hopefully make
the BALUG meeting.

Unfortunately I don't have a URL handy for time, location, etc., but
I'll try and post it when I'm back in the office.

The subject of the talk is, well, Zope, plus a Big Announcement.

I can't comment too much on your problem, your report, although
detailed, still did not show everything, for example, how is it failing?
Does Zope show public pages but never lets you authenticate?

One thing I noticed is that you want Apache to authenticate, then you
try and pass the Auth headers into Zope.  You can't have it both ways,
either Apache authenticates you (and you are quite crippled in this
sense, using the front end web server to do authentication is not
desireable at all, and limits what Zope can do to a great extend) or
Zope authenticates you.  Perhaps I am not completly understanding what
you want to do, but I think you might be tackling too many problems at
once and your conf file apears to be very complex.

First, take out all the Apache auth and SSL and all the other Rewrites
and complexity and just get Zope to work with Apache.  _Then_ add
something else, and get it to work, and so on.  Further, you may want to
consult the Apache docs and inspect the environment that Apache sets up
for PCGI along each step of this process; Apache, for instance, may not
set up all of the CGI 1.1 environment variables in a way that makes Zope
happy when you use SSL.  Or maybe Apache ixnays the Auth header after it
does Auth.  I couldn't tell you either way.

This could very well be a memory error.  It would be interesting to know
if the underlying libraries could handle a dataset this large, in this
case it would not be Zope but the libraries (I can think of no reason
why python couldn't handle a 40MB object, but I can immagine a poorly
written python extension not doing this right, the old ct_sybase module
is a perfect example).  You didn't specify what database you are using.

There is only one reason why I can think of, clicking on the Shutdown
button. 

A quick grep shows sys.exit being called in a few places however, most
specificly in xmllib and pyexpat.  None of these calls set a value of 11
though.

Are you using any XML?  XML-RPC calls?

> Am I completely off base here?

Perhaps, it's a good avenue to look down however.  What I suspect is
that something is happening (like a SIGSEGV) that is causing the OS to
send a signal to the process whose default action is to kill the
process, setting the error code to 11 for some as-yet mysterious reason
(11 has *got* to be the clue however, I refuse to believe that it is
arbitrary, note also that SIGSEGV is signal 11, coincidence?).  A good
exercise may be to run Zope in gdb and wait, when one of these events
happens use gdb to inspect what's going on.  I'm no gdb expert however,
but I was under the idea that it could tell you when signals arrive (or
perhaps stop the process on the arival of a signal...)

I wrote a test script that forked a parent and child just like Zope. 
When I sent the child a SIGSEGV it returned an error code of 332.  Maybe
my experiment is flawed.  

Have you enough time to look that deeply?

To be more specific, it blocks all other requests through that and other
level 2 DAs.  Non SQL related calls and level 3 DA calls will not get
blocked.

Yeah that kinda puts a damper on the whole site... but that's just
because every access is now an SQL related call.

This is not what ZODB sub-transactions do.  Even if you were using a
relational database that has a notion of sub-transactions (Oracle has
'nested transactions' for example) that would not stop the blocking (of
course if you were using Oracle you would be using a level 3 DA...).
ZODB sub-transactions allow changed objects to get flushed to a temp
filestorage so that you can accumulate more object changes then can fit
in virtual memory.  There is no mapping of sub-transaction semantics to
any of the DAs.  In fact, if I remember correctly using ZODB
sub-transactions with SQL methods is Not A Good Thing.  I don't remember
the exact details.

Solutions?  Execute a shorter query or upgrade to a concurrent DA.

Subject: [Zope] More Z SQL head bashing...
Message-ID: <38CE754B.3F7DA16E@nipltd.com>

Hi,

Well, further to my earlier SQL post, here's the code I'm trying to encapsulate, but it doesn't work
;-)
The problem is one of getting a unique, integer, id from MySQL to use as a primary key for an
INSERT. And no, an AUTO_INCREMENT column won't help here 'cos I need to know what the number is
before I do the insert (it generates a reference number, which is used as the primary key, and needs
to be given back to the person doing the submission...)

Anyway, here's the Z SQL Method Code which goes into a MySQL DB connection:

SELECT COUNT(*) as exist FROM sequences WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
<dtml-if "exist==0">
 INSERT INTO sequences SET sequence=<dtml-sqlvar name type=string>, n=0
</dtml-if>
<dtml-var sql_delimiter>
UPDATE sequences SET n=LAST_INSERT_ID(n+1) WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
SELECT LAST_INSERT_ID() as number

When I try to test the method, I get a NameError for exists, which I presume is coming from the
dtml-if. Any idea what I'm doing wrong or other ways of solving this problem?

cheers,

Chris

I had a similar problem I just puzzled through, though I'm pretty new and don't
know the right ways yet :-)

What I did was create another DSQl query (sql_newID) that queried for the new ID
(select max(ID+1) as newID from table) and another sql_exist( select count
*....)  then I used this result, but it had to be within a <dtml-in > tag...

<dtml-in sql_exist>
  <dtml-if "exist > 0">
    <dtml-in sql_newID>
     insert into table (ID, name) values (<dtml-var newID>, <dtml-sqlvar
name...>
    </dtml-in>
  </dtml-if>
</dtml-in>

This worked because I knew the sql_newID and sql_exist will only return a single
value, so the loop only iterates once.  I've never seen the  <dtml-var
sqldelimiter>, though, so I don't know what it does....

Maybe this will help.....

I'm pretty sure now that async_loop is not exiting in my child process
so I'm guessing it is some other type of abort.  I'll try the gdb
avenue.  I'm pretty handy with that, but I've never done much
debugging python or threaded apps so....

I also grepped around the code and looked over every 11, sys.exit and
SystemExit I could find.  This is a real pain.

It's from the ZSQL guide, it lets you put more than one SQL statement in a ZSQL method. 
What I don't understand is why the 'exist' variable stops existing... (maybe I should have called it
something else... ;-)

Time of day can certainly be done. Shouldn't be that difficult to test
by IP, domain and browser, thoigu I admit I hadn't thought of them.


Basically, when called, a banner tests's it's validity agfainst a set of
rules, and those banners that pass are put into a list. that list is
built using weight, and the weights could be modified at runtime based
upon things such as keywords or other tests.

I have a bunch of really bad Python code sitting around here that tries
to do same.  I can't even remember how it does it.

It's got no docs and isn't even a working Zope product.  I doubt it will
help much.  But I can send it to you if you'd like.

That should work fine.  The only weird detail here is that the *icon* of the
method probably won't update correctly unless/until you make it not a Rule
before copying/renaming/moving it.  That's because the icon change is a
kludge.

Access Rules are *NEVER* acquired.  If they were, you'd have to think about
what they might do in every single contained folder.

Subject: [Zope] getting object given path
Message-ID: <Pine.BSI.3.96.1000314132519.17585J-100000@twirl.bitdance.com>

I know I've seen reference to a function to get an object reference
given a URL path, but I can't seem to find it.  It doesn't help
that I've been up for more than 24 hours trying to get this code to
work.

I'm just trying to update a series of objects programatically.
I have a form working that submits the data for a Catalog
query to select the correct objects.  The dtml-in statement
is working fine as evidenced by just printing the meta_data
Id.  However...

If I do a <dtml-with getobject(data_record_id)>, the 'id' variable
has the value of the id of the folder above the one the Catalog is
in.  Doing a <dtml-var> on the getobject call shows me a
'folder instandce'.  None of the cataloged items are folders,
they are ZClass instances.  Earlier I ran through the whole catalog
using the dtml-with construct and a reindex_object call, and the
reindexing worked fine.  But now if I try to call 
propertysheets.info.manageChangeProperties() I get told that 'info'
does not exist, even though that is definately the name of the
propertysheet.

I'm desperate to get this working for the client.  getpath returns
the correct value, so I think if I can turn that path into an
object I can access the property sheets and get them updated.  But I
also want to know what is going wrong with my Catalog and/or
the getobject method thereof.  I'm not sure where to start looking....

I'm running under Site Access, and I'm guessing that is the source
of my problem, somehow.

Thanks for the reference to the DTML Guide...it has helped a lot.  I have
come across something that I couldn't seem to find an answer to.  I have
the following line in my original code that I uploaded from an

replace the echo statements here...

href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80/

I found this snippet of code for an echo and set, but my attempts at
modifying it to work for this have failed.

Hi,

I am starting to look into GUF, but the documentation is
not very well done: it's a bit cryptic and disorganized,
and makes too much assumptions on what the user knows.

Where can I find more help/examples regarding GUF?

The How-To in http://www.zope.org/Members/hippy/GUF_SQL_crypt
is not too good, either. Arrghh... give me some more
hints and I'll prepare another How-To, OK? :)

and it seems that there are quite a few disasters. Horrible
disasters. Sorry, but GUF seems a bit too inmature.

So, let me come back to the original question again, beside
straight GUF, is there any other way of tapping into Zope's
security model and using a generic user?

Hi Olivier,


This sounds like a namespace issue.

When using the Python quoted syntax I think you need to enclose the namespace:

Could you try this:

<dtml-var "myClass.render_1(_.None, _)">


Here are explainations straight from my Zope snippets:

Note you could also pass additional variables:

Subject: [Zope] What if you can use Zope on development server only?
Message-ID: <20000314203306.46566.qmail@hotmail.com>

     Has anyone used Zope in a scenario where you don't have control of the 
production server?  In other words, I'm in a non-profit organization that 
rents space from a web host.  That web host doesn't have Zope installed and 
has no plans to install it.  I *might* be able to put Zope on my own 
personal Linux server, which would really make that machine like a 
development server.  Does anyone have any experience utilizing Zope in a 
scenario where the development and production servers are separate and the 
production server doesn't have Zope on it?

     I'd like to use Zope because our web site has reached the point where I 
really can't manage it myself (Ok, it reached that point over a year ago, 
but I'm finally frustrated enough to do something about it :).  I'd really 
like to be able to give other people in my organization, especially many who 
aren't ultra web savvy tech-heads, the ability to author content so I'm no 
longer a bottleneck to the site expanding regularly.  Zope looks like the 
best open source option to do this with.  I also considered Cocoon 
(http://xml.apache.org/cocoon/), but I know and love Python and Zope looks 
like it's both more mature and more well-established for this type of 
application.

     I also want to add that I *am* considering changing our web hosting 
provider, but due to other organizational changes in the non-profit it will 
have to wait at least six months (it's lower on my priority list than 
finding a replacement for our office manager, for example :).  I guess I'm 
just curious if there's a way to use Zope in my current scenario, without 
having to change to a web hosting company that already has Zope installed.

     thanks for any help anyone can provide,
     Anthony

But fs/select.c(sys_select) (in the linux kernel) DOES return
ERESTARTNOHAND of do_select returns a negative value.  This is, of
course, not documented in the select man page...  come to think of it,
it looks like the linux kernel returns ERESTARTNOHAND instead of EINTER
because (quoting the source comments) "ERESTARTSYS [instead of EINTER]
breaks at lest the xview clock binary, so I'm trying ERESTARTNOHAND
which restart only when you want to" [block comments are mine].

Fishy.

Well, after more poking around and experimenting, I'm able to make an
strace look like what my crashing server does by following these
steps...

start Zope (z2.py)
wait till everybody starts
attach an strace to child z2
wait till strace output shows I'm in select
send child z2 a SEGV

strace output matches what I see in production
event.log matches what I see in production

Now that I've figured this out, I managed to get ulimit set up so that
I will get a core file the next time this happens.

Let's hang on till I see the core.

I'm also going to play with getting gdb to work nicely.  I'm not sure
why this is failing yet.

I originally tried running Zope at pair.com, where I didn't have root access
to the box. I *did* have the ability to run CGIs and telnet in, however. You
can get Zope running in such a scenario. And, if they're running Apache with
mod_rewrite, you can even make Zope serve up your site's root.

    One note though: many ISPs don't want you to run a long-lived process.
If that's their policy, then you'll run into trouble that way.

    As far as running separate development and production servers, I believe
you can get something going. I think someone made a Product that will mirror
your Zope database in separate files. You'll lose all of Zope's cool dynamic
ability, but you'll at least be able to take advantage of the content
management.

Subject: [Zope] Getting the path of an Object
Message-ID: <38CEB515.DB36129E@globalcrossing.com>

Hey all, hope this one is relatively easy...

Background:
1. I have a zope site with folders, subfolders (possible several levels
of subfolders) and objects in them.
2. I built a simple interface to allow a user (with the correct
permissions) to see the tree. 
3. In the UI, each item (folder, subfolder, object etc) has a check box.
Kinda like the Zope UI


The question:
A user checks an object (folder, subfolder, object etc), how do I get
the path to the object that is checked.

i.e.

FolderA
	SubFolderB
		SubFolderC
			index_html

Suppose the user checked index_html in subFolderC. 
How do I get the path (which would be
FolderA/SubFolderB/SubFolderC/index_html)

The test code I am using looks like this (it's in a DTML Method):

<dtml-var standard_html_header>
<FORM ACTION="WhichFilesToExport" METHOD="POST">
<dtml-tree branches=objectValues>
  <INPUT TYPE="CHECKBOX" NAME="ids:list" VALUE="<dtml-var PATH_INFO>" >
        <IMG SRC="<dtml-var SCRIPT_NAME>/<dtml-var icon>">
       <dtml-var id>
</dtml-tree>
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Submit" >
<dtml-var standard_html_footer>

Using PATH_INFO obviously wont work since it returns the PATH_INFO of
this method and not the PATH_INFO of the checked item.


Any thoughts????????????

Thanks,
DR

R. David,

I think you want 
<dtml-in "Catalog(mystuff=mystuff)">
<dtml-with "resolve_url(getpath(data_record_id_),REQUEST)">
<dtml-call "propertysheets.MyProperties.manage_changeProperties(
           blah=foo
           blahblah=bar
           )">
</dtml-with>
</dtml-in>

This will change the properties to whatever you want for the instances
found in the above Catalog search (mystuff=mystuff).

All my best,

     Kevin, thanks for the information!  I do have CGI and telnet ability 
with this host, but I'm surprised that's sufficient to run Zope with.  I 
thought Zope would require a tighter integration with the web server (e.g., 
a mod_zope or something that needs to be compiled in so that Zope can catch 
special Zope-intended requests), and that I'd need root to install it.

     Do I have a misunderstanding of how Zope relates to the web server?  Is 
simple CGI access really enough to install and run Zope?  I was basing my 
understanding on the architecture documentation at 
http://www.zope.org/ZopeArchitecture and 
http://classic.zope.org:8080/Information/Components.

>     One note though: many ISPs don't want you to run a long-lived process.

     Hmm... interesting.  I'll have to look into that; thanks for the heads 
up.

     Yep... that's the tradeoff I figured I would have to accept.  I was 
even thinking I'd have to possibly write my own mirroring script, but wanted 
to see if there was a better way first.  Do you remember anything else about 
that product which might help me do a web search for it better (e.g., it 
definitely used the word "mirror", used the word synchronize a lot, etc.).

     thanks,
     Anthony

Well, I can't give it python, that would defeat the purpose of the 
chrooted webspace.

It seems to me that Zope maynot lend itself to being frozen.

Has anyone out there frozen Zope and managed it to continue to work?

If you use PCGI, Zope will work in a standard CGI environment. PCGI
(Persistent CGI) keeps Zope itself around in memory so that it does not need
to be loaded with each hit. However, you do pay the "fork tax", because the
small PCGI program needs to run. I don't know a lot about fastcgi, but you
may even be able to do that without root and eliminate the fork tax.

OK.. Two points.

Firstly, my appology.  I mistakenly believed sequence-size existed, since it's
previous- and next- counterparts do.  However, sequence-length aparently does.
(there is a reference to it in the ZQR, and it's also in the source code.)


Secondly, your problem stems from the fact that sequence-length is not a valid
variable name in Python.  you must use

<dtml-if "_['sequence-size'] > 1">

Annoying, yes... but that's the way somebody chose to go.  I don't know why,
but it's there.  In fact, if anyone could give me a good reason why it is this
way, I would be most appreciative.

Message-ID: <20000315001632.8621.qmail@hotmail.com>

OK, I know some of you are out there watching. :)

Here is what I found out you can do to use Zope's folder
security features using your own user info database, your
own login interface, and without using GUF (Generic User
Folder). It's kind of simple, so don't expect too much. :)
Hey, but at least it does not lock you up and send you
into a panic attack. :)

(1) Have your own login interface, and use some session
    management product or cookies to keep track of whether
    the user has been authenticated by you.

(2) Create additional user-defined roles at the root of
    your Zope project. (Click on the 'Security' tab of
    the root folder, and scroll to the bottom.) E.g:
    'teacher', 'student', 'parent', etc.

(3) Create an acl_users folder at the root of your Zope
    project. Inside the acl_users folder, add new generic
    users. E.g: 'GenericTeacher', 'GenericStudent',
    'GenericParent'. Assign non-trivial passwords to them,
    of course.

(4) In your standard_html_header or equivalent, you then
    check against your cookies or session data. If the
    user is a teacher, then call:

    <dtml-call "REQUEST.set('AUTHENTICATED_USER',
                acl_users.getUser('GenericTeacher'))">

Voila! Now you can use Zope's security settings to prevent
people from accessing given folders.

Message-ID: <DBEPIFAAMMDGMCBPNKJCIELOCIAA.dell7000@thot.net>

I don't know if this is do-able, but here goes.  I'd like to do something
like the following:

<dtml-var main_header>
<dtml-var "external site">
<dtml-var main_footer>

I know, this defeats the purpose of Zope to some degree, but in this case
I'd like to include an external site instead of employing frames.  Let's
say, for example, that I'd like to showcase a resource located on another
namespace.

I've tried:

<dtml-var "REQUEST.resolve_url(my_external_url)(_.None, _)">

but I get a namespace error for obvious reasons.  I realize that the
header's <body> tags would conflict with the external resources' and hence,
I'm not banking on anything.  I also looked at Redirector and found it to be
great for redirection within the same namespace, but I'm unsure on its
ability to redirect to external resources (or namespaces).

My dilemma is that I am using Zope to design a site and require Zope's
numerous features, but I need to include a CGI-rendered page within Zope
header and footers without using frames.  Ultimately, I intend to re-write
the CGI as a Zope object, but at present I'm at a loss.

Thanks in advance,

Mike

Subject: [Zope] WorldPilot IMAP folder filenames
Message-ID: <E12V23Q-0005Py-00@under.eng.cp.net>

I don't know if there are any standards here, but I'm moving a TWIG
installation to WorldPilotand am running into some IMAP folder
naming problems.

We have TWIG configured to look in ~<user>/imap/xyz for an IMAP
folder called "xyz".  This (per memory) is consistent with how I
recall other IMAP clients working outside of our use of "imap"
instead of the cannonical "Mail" (historical reasons).  Now, I can
edit WorldPilot's MailListRoot to be "imap", but the problem then is
that WorldPilot then looks for folders in ~<user>/imap.xyz (ie the
file "imap.xyz" versus the file "xyz" in the "imap" directory).

I'd thought the defacto standard was to use a directory and then
files underneath that.  No?  Is there a reason for WorldPilot taking
this tack?  It makes the migration less elegant (we can't let people
switch back and forth)..

why do I need a concept of a sub-transaction. Is there just something that I
can call that will commit all changes up until a certain point and then
begin the new transaction? I realize this will break the transaction model
to some extent but if the method is long and each iteration is indepedent
this seems a reasonable thing to do.

To do the work using a shorter query would mean breaking the method up into
chunks and then having to call it multiple times which is pretty ugly.

Tell me how to get a concurrent DA on NT without breaking the bank and I'll
do it.
So far I have:

- MS SQL server - Apparently sybaseDA will work but havn't been able to
compile it on NT. You need certain files from sybase I believe.

- SQLAnywhere - same problem as above.

- Oracle - too expensive.

- MySQL - No transactions.

- PostgresSQL - Got the NT binaries but can't get it working. Also can't
compile the postgresDA.

- ODBC - Not level 3.

As far as I can tell the above represents all the options I have open to me.

It's not immature, just unforgiving :-) GUF lets get down to the bare
bones of an authentication system. Unfortunately this tends to mean you 
have to build it all up from scratch. 

Sometime RSN I'll finish a the one I'm working on that uses postgresql
and I'll bundle that up as a package for people to use, or use as an
example. Not for a few weeks yet, though.

Look in the download section of www.zope.org for one. The first
question, though - what do you intend to authenticate out of? A
database? LDAP?

Think of it this way: under normal circumstances if someone hostile got full
access to your Zope management interface, through a bug or password sniffing
perhaps, your Data.fs would be toast.  That's what backups are for, of
course.  Put XXXPythonMethods in the picture and your entire Zope
installation, any filesystem areas writable by the Zope-process user, and
any services accessible to that user are subject to abuse.  Some of this can
also be handled by backups, but subtle subversion over a period long enough
to render backups worthless is a much greater possibility.

You might end up as a CPU server for arbitrary Python programs.  You might
not.  LOOK OUT, IT'S BEHIND Y..<glurk>

They had to have *something* positive going for them :-)

Message-ID: <000e01bf8e30$2c24b200$0100a8c0@pinol1.sfba.home.com>

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in
general?

Maybe you should make it into a HOWTO. It is really useful.

G'Day.

I need sending mail with multiple file attachement...
But really cool product MIMETools is not ready fully.

Quotation from MIMETools Readme:
"Currently, the MIMETools product's only function is to provide the
<!--#mime--> DTML tag."

When expected implementing of <!--#boundary--> tag?

Thanks,

Perhaps not, but in my experience, Bete ZOPE products are much more stable than

In the site I am currently developing I send of e-mails with attaches.  From a
quick grep of the MIMETools files, you can see the boundary tag already exists.

Here is a quick example:

<dtml-sendmail smtphost="192.168.1.211" mailto="curtis@umd.com.au"
mailfrom="zope@umd.com.au" subject="Attach">
<dtml-mime type=text/plain encode=7bit>
Here is some text.
<dtml-boundary type=text/plain disposition=attachment encode=7bit
name="file.txt">
This is in the attached file.
</dtml-mime>
</dtml-sendmail>

Hello Zopistas out there!

I just stumbled about the threadsafety of different SQL-DAs. I'm 
coming from mod_perl + MySQL so it seemed a natural choice for me to 
also run Zope with MySQL in the background. I'm doing research (= low 
budget) in clinical psychology and have people fill in all kinds of 
questionnaires regularly which I have to store somewhere later. 
Looking at some past messages it seems to me that free and speedy 
MySQL is awfully bottlenecked by MySQLdb and financially-out-of-range 
Oracle rules. But how big is the difference? Does anybody know?

It also came to my mind that I might be missing an important feature 
of Zope: ZODB. For some reason (lack of marketing?) I just didn't 
realize that there is a database behind Zope that I could use to 
store my stuff. Last night I read some documentation but I have some 
questions left open:

Can I access ZODB via TCP/IP socket to retrieve data for statistical 
calculations?

What about performance?

REQUEST.resolve_url().  URL should be unurl-quoted.

getobject actually uses REQUEST.resolve_url and getpath, IIRC, so this may
not help.  But give it a try.

Hi Alex...
thx again !

so, half glop...

Strictly using what you gave me didn't work :(

But, after seeking a little, the following works :

<dtml-var "myClass.render_1(myClass,_)">

But I really don't like it ! Why doesn't Zope give "self" itself ? As normal
python methods do ?

Thanx all !

Normally I'd say try,

href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST['REQUEST_URI']">;weblint"
(the new Zope syntax is <dtml-XXX, but you can use <!--#var XXX--> if you want.

But that doesn't work as REQUEST_URI gives a KeyError.
This is weird because other REQUEST variables seem to work. Any deep 
voodoo Zopistas know why?

<dtml-in "REQUEST.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

Hint:
To see all the REQUEST variables tack on /REQUEST to any URL you have 
(only works with Zope < 2.1.4) or put this in a dtml document
<dtml-var REQUEST>

To just get the environment variables;
<dtml-in "REQUEST.environ.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

So your code should work if you do this;
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST.environ['REQUEST_URI']">;weblint"

(If this seems long winded, it's because I'm writing this as I figure 
it out! :)

Hint: Remember that anything inside "..." is a Python expression and 
Python, *not* Zope syntax applies.

That should work fine.

<sigh>
Ok, I probably shouldn't use them then.
</sigh>

But (you knew there was going to be a but :). They are *so* useful.
E.g. I've got a XXXMethod that imports the following;
import os, sys, string, mimetypes, stat
import DocumentTemplate
from Acquisition import Implicit
from OFS.Image import File
from OFS.content_types import guess_content_type

setting do_XXX=0 gives me;

<!--
  Error type:  ImportError
  Error value: __import__ not found
  -->

Which is fair enough as the docs on the Zope site say import is 
controlled. Can you please be a bit more explicit and let me know 
*what* I can import? The Python code is a bit over my head...

<compromise>
Would you say that you could use a XXX PythonMethod to debug code 
that is going to become an External Method?
</compromise>

Thanks for the help Evan, it's much appreciated.

You might be able to do something with urllib.urlretrieve (in an 
external method) and feed that back into Zope

*vaguely tested*
def doit(self, your_url):
	import urllib
	fn, h = urllib.urlretrieve(your_url)
	if h:
		fp = open(fn, "rb")
		data = fp.read()
	return data

You'll get junk like <HTML> and </HTML> in it, but it's a start...

I could be talking out of a hole in the top of my head here, but here goes:

If you get Andy Dustmans' MySQLdb Module 
(http://www.zope.org/Members/adustman/MySQLdb). It's designed to be 
thread-safe. I've always taken that to mean that if a Zope request 
does a ZSQL query that uses this module, then if another ZSQL query 
comes along (in a different Zope thread) then it is *not* blocked 
until the first query is finished, but runs alongside the first query.

If I'm wrong on this I would *really* appreciate a correction here.

The Digital Creations people aren't overly keen on MySQL because it 
doesn't support transactions, which the Zope system uses extensively 
(I only use it for 'Undo'). For the sort of queries I have (many many 
SELECTs, few INSERTs, that isn't a major problem to me).

I'd reckon so. Look into XML-RPC as an example. Of course you can 
just construct URLs that obtain the data you need (eg have a folder 
with lots of properties of the form prop_n and get the values as 
http://server/path/to/folder/prop_125) and perhaps use something like 
urllib (Python library) to do some machinations at the client end).


>What about performance?

People seem to reckon ZODB is fast enough. I think it's Python 
limited (but again, I could be wrong here). That's possibly where the 
pystone benchmark comes in; check these out;

180MHz 603e (Linux) = 850 (my home Zope system)
300MHz UltraSparc (Solaris) = 2800 (our production machine! :(
266MHz G3 (MacOS) = 4600
500MHz PIII (SUSE Linux) = 5400
700MHz PIII (Win32) = 10150!! (this is really annoying, this box cost 
1100 quid - the same as the yearly maintenance on our Sun iron :(

I have no idea why those last two numbers are so disparate for the 
want of 200MHz. We'll be putting Linux onto the 700MHz box to see 
what happens there...

I struggled a little with this and I now have it working (in development 
anyway) using an SQL database (PostgreSQL) to hold details of users. It 
seems to me that if you need to store a 'profile' on your registered users 
then this is the way to go. You need to read the README that comes with the 
distribution and also read the SQL How-to you've listed below. This do not 
really explain how to use it once it is set up so I added a 'Tip' at
http://www.zope.org/Members/Lunus/lunus_01

I'm still learning but I haven't found any reason _not_ to use GUF yet.

if you mean  and <dtml-if "(OUTPUT == 'PROENG') and 'MATRIX'">

then it is equivalent to <dtml-if "OUTPUT='PROENG'">

if OTOH you mean  and <dtml-if "OUTPUT == ('PROENG' and 'MATRIX')">

it is same as <dtml-if "OUTPUT=='MATRIX'">


which one did you mean ?

If you are not planning of storing thousands of forms and have them
accessed by many users/per second then ZODB is really a good solution and
it is *easy* too use. For example (in the simplest case) you can design a
ZClass that contains all the required fields and a form for the clients to
fill. A method can instantiate the ZClass in a folder and add the
parameters provided by the customer and thats about it in terms of simple
storage. You can have a method that returns the data in some convenient
format as a text file which you can then input into your favorite stat
package. Or you can get fancier and build an xmlrpc method in your stat
package if it supports xmlrpc (ie if your stat package is a set of perl
programs) and get the data directly into your package, or get even fancier
and incorporate your statistical analysis routines inside your Zope
product, but I am getting carried away here :-) (and yes it is doable, it
has been done and if you decide to take this route I have some PCA
routines in python you might want)

zopistas,

during load testing i often see zope / zserver restart or exiting

i'm doing my load testing with apache benchmark, concurrency level
around 10.

"some_simple_oracle_select" being a simple zsql method.

the system is zope 2.1.4 on a suse linux 6.1 

we're going into production soon and we will have to support medium

Subject: [Zope] more on DTML Templates
Message-ID: <200003151443.JAA14787@ml.media.mit.edu>

Here is an update on DTML Templates, and a more in depth explanation
of how they work.

** Update ** 

I've updated the DTMLTemplate product to allow commenting out block
definitions and importing blocks using keyword arguments to the
blocks() method.  The new version is 0.3.0

Find DTMLTemplate at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate


** More Information **

Yesterday, Jonothan Farr (jfarr@real.com) asked about the differences
between Templates and the var tag.  Here's a short summary.


The Template product consists of the "dtml-block" tag and the 
"DTML Template" document type.  In a normal document, the dtml-block
described below::

   <dtml-block myblock>
     Block contents      
   </dtml-block>                   
                                 
works exactly like the following dtml::
                              
   <dtml-if myblock>
     <dtml-var myblock>
   <dtml-else>
     Block contents
   </dtml-if>

In addition, blocks can be used to insert structured text directly into
a DTML document (see the documentation for details)::

   <dtml-block mytext fmt="structured-text">
    * this is

    * structured text!
   </dtml-block>



DTML Templates use blocks in an additional way: to define DTML Methods
that other objects can use.  If the Template 'templ' contains the
following lines::

   <dtml-block myblock>
    Block contents
   </dtml-block>

   <dtml-block anotherblock>
    Another Block
   </dtml-block>
   Other, extraneous text.


then 'templ' will have two block methods that other documents can
access in this way::

   <dtml-var "templ.myblock">              ->  "Block contents"
   <dtml-var "templ.anotherblock">         ->  "Another Block"
   
Any document can also import all of the blocks of a Template into a
local namespace::

   <dtml-with "templ.blocks()">
    <dtml-var myblock>
    <dtml-var anotherblock>
   </dtml-with>

You can also refine blocks using Templates::

   <dtml-block myblock>
    <dtml-var "templ.myblock">
    with more stuff added
   </dtml-block>

   <dtml-var templ>

yields::

   Block contents
   with more stuff added
   Another block


** How is this stuff useful? **

I created Templates because I couldn't design complex and attractive
web pages for Zope using Dreamweaver.  I was always pulling out little
chunks of HTML and putting them into individual methods.  These chunks
weren't valid HTML documents, so I couldn't edit them individually.
With Templates, I create one document with all the HTML code I need,
and block out regions of the HTML using dtml-block.  I upload the
templates (once!) to Zope, and instantly I've changed the definitions
of all the template's block methods.  If I need to make further
changes, I can do it quickly in Dreamweaver.

Templates really makes coherent web design with Zope workable.

Hope this extra explanation helps.

Don't let me discourage you too much.  If you can isolate your Zope, you're
pretty safe.  That means a private or development installation only.  If you
are the only person allowed to touch the management interface, and you
really bite the bullet and do all of your administration through SSL, you
*might* be safe in production.

Right now, they are controlled into oblivion; I have vague plans to allow
some sort of safe import, but no clear idea what would truly be safe other
than trivial "you can use import as another way to spell x = self.foo"
stuff.

That should work well.  XXXPythonMethods and External Methods have very
similar semantics.

I wouldn't recommend it; Changes in the implementation of the authentication
machinery will break this, probably in the next release.  Even if that
weren't true, this trick would be discouraged.  This sort of thing is
*really* best done at the Python level, in a Product.

Subject: [Zope] questions about zope, netscape web server and certificates
Message-ID: <H0001bac07822848@MHS>

Hello all!

I have been posting questions every couple of months concerning digital
certificates and different types of authorization capabilities.  I think I have
finally convinced some people to look at using zope here at work.

Does anyone have any tips or hints for using Zope with Netscape web server on
HP-UX 10.2?  I don't have any way to test this before I get started, and I need
to have my ducks in a row before I start telling someone else how to make Zope
work (I don't have access to the machine that will host Zope).

I have used Zope on WinNT to display data from an Access database, and I have
played around with Zope on Linux (I did not have time to recreate my Access
database on Linux).

One of the things that I am trying to accomplish besides just trying to get
people to use Zope for more general stuff:

1. I need to allow users to login to Zope to approve requests for items (I am
looking at using LoginManager, Wizards and ZopePTK)
2. I need to use digital certificates for authentication (Verisign has a module
for Netscape web server which allows for certificate lookups to verify that the
certifcate is valid and issued by us)
3. I need to pass through the user information from Netscape so that I can keep
track of the user who is approving a request.
4. requests and approvals/denials will probably be stored in a rdbms, but some
information may need to be stored in zodb for searches

Message-ID: <00031510231600.01040@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi everybody,

I'm struggling with some concepts in Zope. The last one is the
DocumentTemplate.HTMLFIle behavior. I was trying to run the Zen 'The (old)
Product API Tutorial' examples when I came accross with this line of code that
looked strange for me (maybe I don't know python enough):

index_html = DocumentTemplate.HTMLFile('poll2.dtml')
...
p = Poll("What's for breakfast?", ['spam', 'eggs', 'toast'])
print p.index_html(p)
------------------^^^

It worked fine and rendered my form.
But what looked strange to me was to give p as an argument. So I tried
p.index_html: it gave me the dtml file (with &lt; for < and so on).

So fine depending on whether or not you provide an argument the rendering is
different. I tried to read the sources to understand better that behavior.

I read somethings about passing mapping object or keywords arguments. But the
question is:
As p.index_html is a DocumentTemplate.HTMLFile instance why can we
provide it with arguments like if it were a method or if we were instantiating a
class?

Hooray! My First Product.

http://www.zope.org/Members/shalabh/iTrack/

iTrack is an Issue Tracking System. It allows a team of people to keep track of
various issues about a project (or anything else under the Sun worth tracking
issues about, for that matter).

Currently this is in development stage (Version 0.2.0) but usable, as long as
you follow the instructions.

Basic Idea:
 o  Issues
 o  FollowUps
 o  Properties of an Issue
     - Title
     - Description
     - Type   (WorkItem, CodeIssue)
     - AssignedTo   (multiple selection of users)
     - Status    (open, closed)
     - (some others not listed)
 o  Types and States configurable through web

For more information:

Hi.

Is there a proposed way how to realize symbolic links in Zope.
I mean, how to place one instance of an object into more than one folder?

This is quite important to information organisation IMHO.

Hooray! My First Product.

http://www.zope.org/Members/shalabh/iTrack/

iTrack is an Issue Tracking System. It allows a team of people to keep track of
various issues about a project (or anything else under the Sun worth traking
issues about, for that matter).

Currently this is in development stage (Version 0.2.0) but usable, as long as
you follow the instructions.

Basic Idea:
 o  Issues
 o  FollowUps
 o  Properties of an Issue
     - Title
     - Description
     - Type   (WorkItem, CodeIssue)
     - AssignedTo   (multiple selection of users)
     - Status    (open, closed)
     - (some others not listed)
 o  Types and States configurable through web

For more information:
http://www.zope.org/Members/shalabh/iTrack/Readme

If you use this, I'd be glad to know.

Enjoy!
Shalabh

Message-ID: <m3k8j4xj0e.fsf@wacko.pdx.net>

With my Zope server crashing about 6 times a day, how can I get the
durned thing to generate a core file?

I have this in my start script:

#! /bin/bash
reldir=`dirname $0`
PYTHONHOME=`cd $reldir; pwd`
export PYTHONHOME
STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE
ulimit -c unlimited
ulimit -a
/usr/bin/python \
     $PYTHONHOME/z2.py \
     "$@"

Which produces this on startup:
core file size (blocks)  unlimited
data seg size (kbytes)   unlimited
file size (blocks)       unlimited
max memory size (kbytes) unlimited
stack size (kbytes)      8192
cpu time (seconds)       unlimited
max user processes       2048
pipe size (512 bytes)    8
open files               1024
virtual memory (kbytes)  2105343

But when I crash with an Aiieeeee error 11, I get no core file.

Box is Redhat 6.1 2.2.12-20.  

I'm able to generate core files from some trashy c code just fine.

Subject: [Zope] newbie - create and call methods ?
Message-ID: <38CFC78F.30634CD9@inpg.fr>

Hello all,

I've been looking in the available zope documentation, listening to
this list, looking in the archive of this list (BTW : are you planning
to add a keyword search ?)... That is to say that I'm used to
searching for the info about open source OS and applications, but I
have to admit I'am almost discouraged using Zope as the doc is really
scarse compared with what is usually found. 

So, sorry, I post my newbie questions :

I would like to create a method to generate a link (href) with a
leading image and text formatting, and so on. I'd like the method to
have two arguments : the name of the link and the URL.

How do I create a method with arguments ?
How do I call a methods with arguments ?
Do I mistake attributes (for docs but not for methods) and arguments ?

If you have pointers to documents I haven't found that...


Thanks in advance,
Greetings,
Eric


PS: Here is what I tryed:
--- DTML method "meth_link"
<h2>
  <dtml-var img_puce_paragraph>
  <a href= "<dtml-var link_url>">
  <dtml-var link_name>
  </a>
</h2>

--- in an other method
<dtml-var name="meth_link" link_name="foo" link_url="la_url">

--- Zope error
Invalid attribute name, "link_name", for tag <dtml-var
name="meth_link" link_name="foo" link_url="la_url">, on line 6 of
txt_user_content

Subject: [Zope] acl_users and differing behaviour with Netscape/IE
Message-ID: <JLEIIKFACBHJPOBKDLODGEEBCAAA.alexander@limi.net>

Hi.

In our development, we stumbled over some behaviour that caused us quite a
headache for a while. We managed to find a less than elegant solution, but
it works for now.

The case is this:

We have the following structure (greatly simplified :)

 rootfolder
  |
  |-images
  |
  |-artists
  |  |
  |  |-acl_users
  |  |
  |  |-Artist1
  |  |-Artist2
  |  |-...etc


As you can see, we have separated the "acl_users"-folder belonging to each
of our artists into the "artists"-hierarchy. All images we use are located
in "images", under the root folder.

The problem appeared when we used DTML similar to the following inside the
artists-folder:

<dtml-with images>
  <dtml-var picture>
</dtml-with>

In IE, this would work just fine, Zope got the "picture" object from the
"images" folder and displayed it - no problem. But with Netscape and
Mozilla, we got authentication problems. It seemed as though Netscape
insists on sending the authentication request no matter what, and is
actually denied access to material that can be read by anybody (ie: the
objects in our "images" folder).

As far as we can see, this is a result of us having an extra "acl_users"
folder in the "artists" folder. Thus the logged in artist is not a user in
the root hierarchy, but only from "artists" and further into the tree.

We've solved this problem temporarily by putting duplicates of the images in
the "artists" folder.

My questions are thus:

1. Should we move the "acl_users" folder to our root folder? If possible, we
would prefer separating the artist users into their own folder, to avoid
clutter. But they should be able to access the rest of the site, like any
anonymous user.

2. Is this a problem with the way Zope authenticates users? Shouldn't users
that don't authenticate correctly at least have access to the content
readable by anonymous users? Or have I done something terribly wrong? :)

You see, we plan on having a "listeners" folder too, where we are going to
store individual listeners' preferences (what artists they want to be
notified of, what music categories they prefer, etc) - and I assume we will
run into the same problems here - users being authenticated only in the
"listeners" folder and below. They should be able to browse the normal web,
however, and add artists to their notify-list. Does this acl_users have to
be in the root user folder too?

Please CC me, as I don't have access to the list at the moment.

Regards,


Alexander Limi.

In the beginning, there was DTML.  DTML did not have expressions as was
designed to look very much like HTML, so names like sequence-item were
chosen.  Later on, expressions were added.  Names like 'sequence-item'
were obviously not going to do, because in a python expression it looks
like a subtraction.  So, the DTML namespace was given the name _, and
given a mapping interface which allowed you to look up names in the
namespace.  Thus was born _['sequence-item'].  _ is a mapping like any
other.

It's really not that bad, just kinda ugly.

I'm running WorldPilot 1.0.4 on Zope 2.14 with the stock IMAP server

RedHat). Everything works fine but I can't create or use new folders.
WorldPilot properly displays the mail in my "Inbox" which is located at
"/var/spool/mail/sbaird" on the server. I can create new mail foldersrs
from within Worldpilot, but I can't access them from WorldPilot (I can
from other IMAP clients). The mail folders created are placed in
"/home/sbaird/" as "INBOX.personal" etc. I suspect this is just a
directory mapping issue but after reading everything I can I can't
figure it out. Any help would be appreciated.

The Python DB API spec 2.0 talks about different levels of thread 
safety. MySQLdb has threadsafety level 1 (= threads my share the 
module but not connections), the ORACLE db has threadsafety level 3 
(= threads may share the module, connections and cursors). I wonder 
what that means in % performance gain in high traffic situations. I 
have no idea where the different levels of threadsafety kick in. Any 
experienced users?

I was rather thinking of connecting directly to ZODB (in a kind of 
server mode) via TCP/IP - not via Zope. But I guess that's an 
aberrant thought that would rather be applicable to connecting to 
ZEO. Still I feel like I'm only beginning to understand but in about 
two weeks the new production site must be ready running zope ;)

Actually I'm not planning anything except to be prepared. I'm only 
starting and have no idea what I will end up with. So of course I am 
looking for a scalable solution. From what I've learned from the list 
scalability seems to be a weak spot of Zope (while e.g. the latest 
Enhydra includes a failover solution). I have no idea how much ZEO 
costs. (People from DC could you help here? I couldn't find a price 
on the website.)

I tried to understand ZClasses and read the documentation a couple of 
times but it didn't help a lot. So now I'm using Python classes which 
is very easy (maybe only because it's better documented). Can you 
e.g. simply add a dictionary or a list of dictionaries to a ZClass 
and access each element individually?

Would be nice if I could get back to you some time later to talk 
about the PCA. :)

Subject: [Zope] Need help with site structure
Message-ID: <NDBBKGBPJMFODAAFNMKEGECMCAAA.mduvall_22030@yahoo.com>

I'm setting up a Zope site, and would like to know if the approach described
below makes sense. I imagine this is a no-brainer for the more experienced,
but I'd appreciate some feedback so I don't go too far afield. Thank you!

In a nutshell, the site will give customers the ability to run reports
against application data that we're hosting for them. There will also be an
area for developers to log on and tweak parameters of the hosted app.

User Management
---------------
To keep the user accounts organized, I'd like each customer organization
(say, ABC Corporation) to have a folder that contains an acl_users folder.
I'd merely prefer to look at a few users at a time instead of seeing them
all together.

When a users logs on, I'd like that user to have a role of custUser,
custAdmin, or custDeveloper. I'd define these roles at the root. I'd also
like the user to acquire (if that's the term) properties of the customer
account, such as customer ID, so customer ID would be a property of the
customer folder(?).

So folder-wise there'd be;
root/customers (containing...)
root/customers/abc_corp
              /...
root/customers/xyz_corp (each with an acl_users folder)

Site Content
------------
This side of the site seems straightforward. The user's role will determine
what's visible/accessible, and the user's acquired customer ID will
determine which application data can be included in reports.

root/mysite (will contain content sub-folders, such as...)
root/mysite/eggs
           /spam
           /reports
           /developers (custDeveloper role required for access)
           (more content sub-folders)

So the question is...
---------------------
My main question is the user authorization / acquisition piece. How do I run
username and password through the contents of the root/customers folder?

If the folder layout described above makes sense, is this authorization
piece a job for a ZSQL Method, for GUF, or for both? Last week's "virtual
folders / url's" thread provided interesting info ZSQL Methods.

Also, any comments about holes or vulnerabilities in this approach are
welcome.

Thank you.

Mitch Duvall

Message-ID: <38CFD0D8.B5391DC8@funcom.com>

I've seen numerous postings about this, but so far I have been
unsuccessful in successfully subclassing the Image with my own ZClass
(called VProduct for this case). Here's what I have managed to do:

* Create my new VProduct ZClass with Image as a base class
* Add a couple of new simple (string) properties to VProduct
* Modify the VProduct_add and VProduct_addForm methods so that my new
properties gets asked for and filled in (and using the system clock to
generate  unique id's)

This seem to work great, and I can move about in the Zope filesystem and
add instances of my VProduct class as I want to.

I have not been able to successfully integrate the file upload feature.
What I have done is:

* Add an input file <input type=file name=file> in the addForm method
* Putting a file name in this field and pressing submit button

From here I am not quite sure what to do with the image, but from
browsing earlier postings about this, it seems to have something to do
with calling manage_upload one way or the other.

In the VProduct_add method, I have the following special code:

<dtml-call "REQUEST.set('ts', ZopeTime ())">
<dtml-call "REQUEST.set('id', _.str(_.int('ts')))">

The above code generates a unique id for my VProduct instances, and this
works fine.

Inside the automatically generated:

<dtml-with "VProduct.createInObjectManager(REQUEST['id'], REQUEST)">

further down in the VProduct_add method I have the following stuff:

  <dtml-call "propertysheets.Basic.mange_editProperties (REQUEST)">

that code should take care of modifying the properties of my VProduct
instance (and assumes I guess that the input field names match the
property names). This seams to work great.

Right before the "propertysheets..." line I have tried adding the
following:

  <dtml-call "manage_upload(REQUEST['file'])"> 

It does not generate an error. But it does not seem to manage the upload
part either, since my VProduct instance gets the content_type
"text/plain" (instead of image/jpeg which is the right type for the jpeg
file I try to upload). And when I try to "view" the VProduct instance, I
get a simple <img src="91231912" alt="sometext"> tag which displays like
a missing image in a web browser (no wonder since the content_type is
wrong). I have tried manually setting the content_type to "image/jpeg",
but the image still does not display correctly. My guess is that the
image never got uploaded.

Any ideas on how to handle the upload properly? I've done some 30
searches through the list archive, without any clear answers to how the
image uploads are handled (or should be handled). I've looked carefully
through the howto's but have not found anything.

Any help would be appreciated.

What I know is that you have to use Named Parameters in method

ex:
myFunction(url, image):
    return '<A HREF=%s><IMG SRC=%s></A>' % (url, image)

and the dtml call looks like :

<dtml-var "myFunction(url='http://www.zope.org', image='logo.gif')">

I am not sure of all...But I think it is the "spirit"...

Good luck !

You don't.  But that's what you were asking so that's what I was
answering.

I don't think the problem is that a transaction needs to be commited,
the problem is that the DA is engineered to block until it completes the
task at hand.  Even if you did call get_transaction().commit() from
python or an external method or whatever, I don't think it would unblock
your call.  You can try it, of course.

I don't know if we have immediate plans to bring the ODBC DA up to level
3.  Probably not any time soon unless it is a customer requirement.

Another option is to threadsafe the ODBC DA yourself.

I know, I know. :) But how otherwise do I get you people
to come out from hiding without posting a hack like that? :)

GUF has problems and we have to face it. If a product takes
a few days to install, if a product locks newbies up and send
them into panic attack, it has problems. Please just look
up past postings in the mailing list... headers like "Bad...
very bad" and "GenericUserFolder has locked me out" are
just heartbreaking. :)

If I have time I'll find something better, or make something
better. :)

Evan:

(1) When the the next version of Zope coming out?
    It fixes a tiny bug that I reported. :)
    Will it have a native feature like SiteAccess that
    you have mentioned before?

(2) Could you describe briefly how the traverse machinery
    works in Zope? I'd like to take a look into it. Which
    Python files are involved?

regards!

The boundary tag is implemented in the MIMETools product.  Because it is
only meaningful in the context of the mime tag, I did not explicitly
list it in the readme.

I'm not certain if the MySQL DA is level 3 (threaded) or not.  I am
certain that MySQL does not support transactions and Zope does.  What
this means is, if you call some SQL and later on an error occours, Zope
will "roll back the transaction" and discard any changes you made in
Zope.  If Zope is used with Oracle, Sybase, ODBC, Postgress or any other
database that supports transactions, then those databases will
synchronize transaction commits and rollbacks with Zope.  This means
that your data is allways consistent across databases, which is a good
thing.

This may not effect you.  Your database may be entirely read only, in
which case it's not a problem at all.  Just keep in mind that you are
missing an important piece.

Keep in mind that this is not an _relational_ database.  It's an object
database.

Yep.  You can access the ZODB through HTTP, FTP, XML-RPC and WebDAV. 
That's really what Zope is, it's a network aware application on top of
an object database.

The question is really too vague to get a specific answer.

Well, it's syntactically correct.  Whether or not it does what you want
it to do we can't tell because you didn't say what you want to do.

The expression "'PROENG' and 'MATRIX'"  will _allways_ return 'MATRIX'. 
So 'OK' will only be rendered if OUTPUT == 'MATRIX'.  In fact, this:

<dtml-if "OUTPUT == 'MATRIX'">
  OK
<dtml-if>

does exactly the same things as your code.

There apears to be a segment violation somewhere in Zope which was

Subject: [Zope] Zope and enterprise data access
Message-ID: <4.2.2.20000315131747.00ba5600@saladin.aisys.com>

The company I work for is starting to get more requests for web sites which 
need to have access to enterprise data.  We have several Java people on 
staff and most of these projects are currently being done (or planned to be 
done) using JSP/Servlets and Enterprise Java Beans.  The problem that I 
have with this solution is that there is very little in the way of content 
management available in this environment, without rolling your own.  What I 
would really like to be able to do is build the client interface using 
Zope, so I can easily blend static content, dynamic content and content 
management, with access to enterprise data.  I know that Enterprise Java 
Beans are accessible via CORBA, so theoretically it should be possible to 
access this data through Zope/Python.

My basic question is this, is there anything available (free or otherwise) 
which would make it fairly easy for Zope to interact with something like 
Enterprise Java Beans?  Are other people trying to use Zope in an 
environment where access to enterprise data is important?  If so, are there 
other solutions to this problem?  What I would really like to be able to do 
is use Zope in combination with a DBMS to build smaller systems, but when 
the need arises, I would like to be able to scale things up to allow for 
distributed data object access.

Any thoughts, suggestions or comments on this subject?

Thanks.

Hmm.. unfortunatly there is no good way to do this from DTML except to
use manage_FTPget().  Yuk.  This lack will be fixed in the near future
when we re-do alot of the Zope interfaces.  Currently we are in the
middle of documenting all of the existing interfaces which obviously
must come first.

I *think* you want REQUEST['file'].read().  manage_upload wants a string

You can create your own kind of splitter and replace Zope's (note that
Zope's splitter is written in C, and is found in
lib/python/SearchIndex/Splitter.c) you can write yours in C or Python.

I have not touched the authentication machinery yet so I must rely on
other Zopistas efforts. There is a LoginManager which is part of the PTK.
Seems to be well thought out, and it seems to provide a very general and
broad solution to the authentication problem, but I have no idea whether
or how it works.

Another useful add on is for GUF to ship  a complete example of its usage
based on standard Zope objects (Folders etc). Maybe as an exported
folder that the user can optionally import.

I would solve this in the submit action by doing a select for the data before
doing an insert.

Example:

(form_html)

<form action="submit_html" method=post>
....
</form>

(submit_html)

<dtml-in select_data>
<dtml-if sequence-start>
<dtml-var error_message>
</dtml-if>
<dtml-else>
<dtml-call insert_data>
</dtml-in>

Dan,

It's gotta be a connection string or username/password problem as
defined in your interfaces file.  Are you sure the port number of the
remote server is correct in the interfaces file?  You can use isql from
the box that Zope is on to connect to the remote Sybase server?

First off let me say that I have searched the Zope archives.  I finally

Dan,

You need to install the Sybase client libraries on your Zope machine to
use the SybaseDA.

For more info, please contact the Zope mailing list at

I guess I'm confused.  I can't get to the actual jpeg image?  Here's what I'm
trying to do.  I want to create a form to upload data.  This data can be off any
type.  The data is stored in an ODBC database table along with it's mime type.
So, on the upload action form, I need to 1)  get the mime type and 2) get the
actual data.  Another part of the site mails off these items as attachments.
I've heard that the mime type should be uploaded along with the data, I just
don't know how to get to it.

You have a few (untested) choices:

1) Put the following in a DTML Document or Method:

     <dtml-call expr="REQUEST.set('first_sequence', [1, 2, 3])">
     First:<br>
     <dtml-in first_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

     <dtml-let second_sequence="[1, 2, 3]">
       Second:<br>
       <dtml-in second_sequence>
         <dtml-var sequence-index>: <dtml-var sequence-item>
       </dtml-in>
     </dtml-let>

2) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Tokens". Give it the value "1 2 3". Put this as the document
   source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

3) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Lines". Give it the value:

     1
     2
     3

   and put the following as the document source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

4) We could make a Python base class
   (lib/python/Products/MyClassBase/MyClassBase.py):

     class MyClassBase:
       def __init__(self):
         self.my_sequence = [1, 2, 3]

   and create a file (lib/python/Products/MyBase/__init__.py):

     from MyClassBase import MyClassBase

     def initialize(context):
       context.registerBaseClass(MyClassBase, 'MyClassBase')

   Now restart your Zope, go to the Control Panel, and Add a new product
   called "MyClass". Inside this product, create a ZClass called
   "MyClass". When creating the ZClass, select MyClassBase as a base
   class. In this ZClass, on the Methods tab, create a DTML Method
   (say, index_html) with the following source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

   Then, go to your root, drop an instance of MyClass with an id of
   "MyInstance". Now, navigate to http://your.server.com/MyInstance.
   Voila.

I probably missed two or three other ways to to it. But, I hope one of
these is what you're looking for.

Not directly from DTML.  You need to use a method on the Image object. 
manage_FTPget().

This is different from the first question that you asked.  In this case,
when your form uploads the file contents, ZPublisher will marshal that
into a StringIO object (which acts just like a python file object).  In
this case you can just do:

<dtml-var "REQUEST['name_of_form_element_that_is_the_file'].read()">

and get the 'contents' of the file.

In this case, your taking about a Zope 'Image' object, _not_ a standard
file object like you get when you upload data.  For this you need
manage_FTPget().

Has anyone noticed their dtml code mysteriously reverting to a previous

In other words suppose you have a dtml document called DocA. It
contains:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Several days later you change
DocA to:

<!--#var standard_html_header-->
<h1><!--#var id--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Later that day or several days
later, after a manual shutdown and restart, DocA has reverted to:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

Ok, I guess this is where I get confused. When is the REQUEST['file']
instance
a string and when is it not? If I try to replace the manage_upload call
with
your suggestion, I get a message saying:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which indicates that REQUEST['file'] is a string at this stage (and
probably
the filename or similar). From the input form I guess "file" is a string
(at
least that is what it looks like in the input form - the filename) at
least
until I press the submit button. When it actually changes from the
filename
to a file I do not know.

Any other suggestions on how to get hold of that file?

Thanks,

Marius Kjeldahl

Your form element should be:

<input type=file name="file_name:file">

The ':file' is necessary to marshal the file into a file object.  I was
going on the assumption that you had done that otherwise as you've
discovered it will turn it into a string, which you may or may not want.

MySQL takes a lot of criticism because it is (a) non-free, (b)
non-transactional. Non-fre I won't get into.

Non-transactional means that it doesn't support transactions. :) So what
are transactions? Say you own a bank and Joe transfers $50 from his
checking account to his savings account. The program removes $50 from
this checking account, but the disk is out of space and an error occurs
putting it into a savings account. Is Joe out $50? Not if it was a
"transaction" where all-or-none of a sequence of events happens. If at
any point an error occurs in the transaction, everything is rolled back
($50 is back in his checking account and the error is reported). MySQL's
lack of transactions rule it out IF you need transactions.

Another limitation of MySQL is that it doesn't support very large
databases. This usually isn't an issue.

Another solution is PostgreSQL, which is a free relational database
system (see http://www.postgresql.org). Postgres is very powerful and is
probably the most powerful free db by far! There are some drawbacks:
 * Last I heard, the PYTHON INTERFACE (not PG itself) for postgresql is
not threads compliant. You will have to kludge something with locks to
use it(?)... any ideas on this one, anyone?
 * You cannot remove or modify a column on your database. You can rename
the column and let it hang, or recreate the table. For changing schemes,
this can be a real pain.
 * Text beyond 16K must be stored in a large object - this is a pain.

It has some advantages:
 * Transactions
 * Super docs
 * Great reliability
 * Most of ANSI SQL Compliance
 * Stored procedures
 * Some real nice datatypes for everything from money to geometry

Alas, there is Oracle8i. It has some drawbacks:
 * Installation is a bitch! You usually have to edit kernel header
files, recompile, set mount points, apply patches, arg!!
 * Complexity; Oracle VERY complex even after you get it up and running
 * The Oracle/ZOPE interface does not have a Setup file for 8i. You'll
have to write one to compile it. (Or, email me for the one I got a hold
of)
 * Fewer column types than postgres

And the advantages:
 * Transactions, great reliability, and great SQL support
 * Java support
 * Plenty of docs. My favorite Oracle stuff is at photo.net (the web
page of some MIT guy)
 * Good interfacing with Zope, thread safe

In general, if you're willing to spend the overhead of a killer learning
curve, use Oracle8i.

Ok, I have changed my form element to what you suggested. These are the
results I am getting with various <dtml-call> tags in the VProduct_add
method (called after filling in VProduct_addForm):

* <dtml-call "REQUEST['file'].read ()">

Error Type: TypeError
Error Value: argument file was ommitted

I guess this is because no field in the form is named 'file'. So I try:

* <dtml-call "REQUEST['file_name'].read ()">

..and I get the same error. I even tried to name="file:file" in the form
element, and using REQUEST['file'].read () in the call, but then I get:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which I guess means that it now has the 'file' variable, but it is still
a string.

Any other pointers, or references to where I can read more about the
file stuff?

Thanks in advance,

Marius Kjeldahl

REQUEST['file'].read ()
                    ^
            Notice this space?

That space isn't supposed to be there.  You're supposed to be calling a
function with no arguments, the () has to be right next to the "read". 
The way you have it right now, it's looking for an attribute called read
instead of a function.

Actually you can get the image data as <dtml-var "my_image.data"> where
"my_image" is the name of your image object.

The following DTML will return the actual image to a browser (tested):

<dtml-call "REQUEST.set('Content-Type', my_image.content_type)"><dtml-var
"my_image.data">

It is crucial that the DTML method contain no extra whitespace, though, as this
will be interpreted as part of the image data.

Message-ID: <Pine.BSF.4.21.0003151720200.1009-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively (but I'm willing to share).


Announcements

  * The latest versions of the Zope Content Managers Guide, Z SQL
    Method User's Guide and DTML Reference Guides is available in
    postscript(ps) format.  With luck, the technical problems of the
    previous versions have been fixed.

    http://www.zope.org/Members/Pam/PSversion

  * Check out the new Zope Documentation Projects page that lists
    current Zope documentation projects and their status.

    http://www.zope.org/Documentation/Projects/Projects

  * Martijn Faassen <faassen@vet.uu.nl> has established a Zope-XML
    mailing list.  The intent is to discuss Zope's XML infrastructure.

    http://www.egroups.com/group/zope-xml/info.html


New Products

  * Software Product: iTrack Issue Tracker Product, by "shalabh"

    iTrack allows a team of people to keep track of various issues
    about a project. Currently this is in development stage (Version
    0.2.0) but usable, as long as you follow the instructions.

    http://www.zope.org/Members/shalabh/iTrack/

  * Software Product: ZGDChart Product, by "teyc"

    ZGDChart uses gdchart to draw charts.  This product comes with
    Windows binaries and source for non-Windows platforms.  This
    initial development release is 0.3.

    http://www.zope.org/Members/teyc/ZGDChart

  * Software Product: DTMLTemplate, by "halazar"

    DTML Templates are documents that allow blocks of text to be named
    and made available to other documents. The basic building block of
    templates is the DTML block tag, which can also be used with other
    DTML document types. Templates export their blocks. Another new
    tag, the suppress tag, allows block definition without rendering.

    http://www.zope.org/Members/halazar/Products/DTMLTemplate


Updates

  * Software Product: jcNTUserFolder, by Jephte CLAIN

    This product authenticates Zope users against an NT domain
    controller.  All users are encouraged to upgrade to this version,
    0.0.3.  Unfortunately, the upgrade is incompatible.  You will lose
    any role settings.

    http://www.zope.org/Members/jephte/jcNTUserFolder


Zope.org items

  * How-To: The Debugger Is Your Friend, by Michel Pelletier

    This HowTo is an invaluable resource for those days where if I get
    one more mysterious traceback, just one more and I swear I'll
    crack.  It explains how to step through Zope code line-by-line
    with the python debugger.

    http://www.zope.org/Members/michel/HowTos/TheDebuggerIsYourFriend

  * How-To: How to test your products without (re)starting Zope, by "teyc"

    This HowTo describes testing Zope products within a python
    interpreter without starting the Zope server.  This rather speeds
    up the code-test-curse-code cycle, because it allows you to
    quickly reload your Product with each change.

Message-ID: <B4F57760.14F5%Jatwood@bwanazulia.com>

I have some data returned by a SQL Method that I want to randomly pick from.
Since I cannot get the SQL Statement to return random data sets I was going
to use the "_.whrandom.choice" to go over the SQL list and create a new list
of the randomized choices.


This will go over the SQL Content
<dtml-in sqlMethod size=10 start=query_start>
</dtml-in>

But how do I create a list? (in Python I would just say list = () and a
list.append()

TIA,

Hi..

I just uploaded many files with load_site (thanks Itamar!), but
I ran out of disk space while doing this.
Seems as the last transaction corrupted the Database seriously.
When I try to delete the folder where the errors are I get:
Error Type: CorruptedDataError
Error Value:

The same with packing database.

And when invoking Undo, i get something like:
long int too long to convert

Any ideas what I could do to repair my database and deelete the corrupted
folders and start over again?

Thanks in advance,
    Mario

Havn't been able to so far. It seems you have to have a reasonably complete

That is a possible option. Does anyone know what the issues with this are?
From memory I think the non-thread-safeness of the odbc drivers themselves
was not the only problem. I suspect the python odbc interface might have
been not thread safe also. Can anyone confirm this?

Dan,

Please cc the Zope list while we're talking about this.

What is the -H option to isql?

Can you import the sybase module from python as per the build
instructions?

What user are you running Zope as?  Does that user have permissions to
the sybase client directory?

Hi

i've spent the day trying to make this work so i thought i'd see if
brighter minds could illuminate the darkness of my night.

I'm trying to setup an email archiving system in Zope. I've got the
email retrieval setup in an separate python script and a couple of
ZClasses setup in Zope to archive/catalog the emails. My problem is
getting the parsed email info(to, from, body, etc) from the external
script into my Zclasses. i've tried xml-rpc but i keep getting server
errors. i connect to the server and try

zope.project.archive.addEmail(id)

but i keep getting a 500 Internal server error message. addEmail is just
a wrapper around the constructor which expects only one parameter the id
of the email Zclass object to create( just something to debug before i
pass in all the params). So what gives? i can call the method from the
web with

http://localhost/project/archive/addEmail?id=xx

but how do you call a dtml method with args from xml-rpc. fyi i'm using
amos's patched xmlrpclib for authentication (i fixed the import errors)

i've trying to reimplement this in an external methods but i would
really like to know how to do it with xml-rpc. btw 

Thanks

Kapil

The Login Manager looks good because, unlike GUF and UserDb, it allowed
me to use the admin/supervisor password to authenticate straight away 
and so didn't lock me out of the directory.
I actually gave up on GUF because I _couldn't_ get it to let me in in
the first place to set up my db methods. The password that is supposed
to be built in didn't work at all, neither did the supervisor one.

To me this is the biggest problem with the other existing systems, that
they lock you out of your site and there is little you can do about it.
(In UserDb I had to comment out parts of the security code to get it
to let me in and set it up properly. After it was set up it worked fine
and I could put the code back.)

All authentication stuff from a database is going to require the
person to customise their own sql we can't make custom authentication
methods any easier than that, but in the simplest case this should
be _all_ they have to do. The supervisor password should _always_ work
in any authentication method from the beginning and it should be made
clear that people are going to have to authenticate using that particular
password until they have the rest of their site set up.

Anyway, the LoginManager looks very clean. It already doesn't have a
lot of the old problems and I like the abstraction. Now I just have to
finish getting DCOracle working (annoying truncated .so files...).

Yeah that was probably me, not to slam MySQL, it's fast, it's free, and
it's stable.  It's lack of transactions however means that you have to
be aware of and live with the possibilty of inconsistent states of data
between MySQL and Zope.

For read only operations, or low-write, or if an external application
handles inserting your data and Zope only reads it, this is not really a
problem.  Also, it's only really manifest if you change the database and
then change something in Zope and an error occours.  If you can isolate
your SQL calls as much as possible, then this shouldn't be a problem.

I posted a work around for that on this mailing list a couple of days ago.
And yes whilst it is frustrating it is no where near as hard as writing 
an authentication product from scratch (which from experience is difficult).

Last time I used it came with a very simple example already. All you need
to do is add in your logic and you're away. The SQL Howto on the website is
very informative (cheers to whoever wrote that).

Sorry I think that the GUF is also very clean and quite easy to work with.

I think GUF is great as it is. Thanks a lot to Zen for contributing it.

I would have to recommend postgresql. I've got a prototype ecommerce site 
running with Zope at the front, some python in the middle and postgresql
at the backend. Currently it is a prototype so we only have about 20,000
items in there at the moment however it seems to work very well. (Once I 
brushed up on some of my SQL).

Check it out at http://www.postgresql.org

I see a couple of issues with this:

1)  This may not scale well; if select_data becomes large you may
be spending a while in the dtml-in loop.

2)  There could still be a race condition here, between the check for
data and the insertion (especially coupled with the above point - the
probability would increase proportionally with the load of the machine
and the size of the table). I say "could" here (guardedly :-), because
I don't know how Zope's transaction semantics are implemented, and how
they affect the DA that you're using (does anyone have any pointers to
documents?  I've just started reading "How to Write a DA", and this
mentions the distributed commit protocol).

I'm not sure if a solution to the original problem is to surround
the insert with a <dtml-try> tag;  I'm going to try this myself
sometime today (if I get some spare time :-).

My experience with SyBase is that the adapter development is
kind of slow, and only Linux platform is supported. And
currently it has some glitches with some data types (decimal
with 10 or more digits), it does not support stored procedures,
and the implementation in Zope 2.1.4 crashes when you have
date fields ending between 59 and 60 seconds (e.g: 59.23 sec).
Also, when there is database problem, the adapter very often
just hangs and lock the database out, requiring a Zope reboot.

So, SyBase in Zope is not really in great shape. I don't know
about other databases, maybe other database adapters have
problems, too. SyBase adapter is workable for me (after I
patched the problem areas), just not that great in its current
shape. It has transaction, though, which you definitely want.
The thing is, SyBase itself seems fairly solid, it's just the
Zope adapter that is still not perfect.

Hung Jung

Subject: [Zope] DateTime exceptions
Message-ID: <00031611243805.02516@localhost.localdomain>

Greetings,

A workmate of mine has had this problem also, and now it's happened to me.

I cannot catch exceptions from the DateTime object!

My code:

<dtml-try>
    <dtml-call "REQUEST.set('delDate','%s/%s/%s' % (delYear, delMon, delDay) )">
<dtml-except>
    <dtml-call "REQUEST.set('delDate',0)">
    <font bgcolor="red">You have entered an invalid date.</font>
    <dtml-call "REQUEST.set('Error',1)">
</dtml-try>

Now, from my understanding, this should catch ALL exceptions.  So why, when i
give invalid values (like -1) does ZOPE give me an error page?

Is this some deficiency in the way the DateTime object handles exceptions?  Or
is there some funamental zen i'm not groking?

I would write the select_data query to only select a single record, i.e. the one
I'm worried about duplicating.

Heh. I certainly wouldn't want to do it from scratch myself...
I just tracked down your work around again and now remember why it didn't
help me. I actually have a UserDb in my root directory and that's what I'm
trying to get rid of (Since I'm moving to Oracle anyway I thought I'd
change to a supported product since UserDb has been giving me a few obscure
problems at times.) So since it doesn't support the admin user either your
suggestion doesn't help. I will, however, try making a normal user folder
in a subdirectory and then try to set GUF up in a subdirectory of that...

Grin. Seeing I never managed to get into GUF's management interface in the
first place I can't really comment on how clean it is.

IIRC, all you need is the libraires, a seperate download. I have a
couple machines that only have the libraries, and work just fine. Of
course, they are on various unixen, YYMV on NT.

Firstly, I'm not a member of this mailing list, although I have an archive
of over 2000 messages from it.  Could anyone replying to my message please
reply to tim_haines@hotmail.com as well as the list?  Thanks.


I've been developing a site using nt4, Access, and the odbc plugin.  Things
work great - most of the time.

I've noticed that occaisionally I get any error message that mentions
tpc_begin.  When I do a refresh, the problem is gone, and the site works
fine again.  I've also noticed that this normally occurs the first time a
database query is executed after a reboot.

Does anyone know why this would happen, or have any insights at all?  I look
forward to hearing from you.

Tim.

One thing I should point out firstly is that the LoginManager inside
the PTK isn't finished yet and the developers don't suggest actually
using it just yet.

While I said it looks great (and it does) and it accepts the admin
password it does _not_ yet have the api in place to let you authenticate
from SQL. So you probably want to wait a bit still.

But after saying that if you still want to look at how they are going
you need to actually install the Portal Tool Kit first.
Have a look at it's install instructions at:

Can you provide more specific detials? I am running two seperate systems

Hello.

Many thanks to all for your answers on my recent question about MIMETools.
Really, tag <!--#boundary --> is implemented now, and works, but...
I need sending mail with multiple file attachement...
Combination of several tags <!--#boundary --> working...
When I tryed insert tag <!--#boundary --> into tag <!--#in -->,
Zope said: "Unexpected tag, for tag <!--#boundary ..."
Because <!--#boundary --> is only meaningful in the context of the 
<!--#mime --> tag.
We have loss of this context? Below example of my stupid code.

[ --- begin code snippet ---]

<!--#mime type=text/plain encode=7bit -->
just example text...

<!-- #in "files_to_mail" -->
<!--#boundary type=application/octet-stream disposition=attachment 
encode=base64-->
<!--#var sequence-item -->
<!-- #/in -->

<!--#/mime -->

[ --- end code snippet ---]

Any ideas?

Dima.

Are you just afeter a single random item from a ZSQL query? 
If so:

<dtml-with "_.whrandom.choice(_['getcategories'])">
	<dtml-var category>
</dtml-with>

Works for me. In this case, 'getcategories' is a ZSQL method that
returns a list of categories, consisting of:
"select category from linkCategories"

Message-ID: <38D077D6.CC74ABB3@suprize.com>

Hi,

    Zope seems to evaluate expressions in an unconventional way.
Say I have three properties, a=3, b=5, c=7 set in a Folder. In
a DTML Document I tried to say <dtml-var "a/b*c"> and got result
0. The expression was evaluated as a/(b*c) and rounded off. Is
not the expression supposed to be evaluated as (a/b)*3? The
result is not correct still if we put it this way:
<dtml-var "(a/b)*3">. I still got 0 as the result. Did I miss
anything fundamentally or is this a, bug?

Hi Zopistas,

I now that the failure is because the object in the namespace is "PARENTS". So what is the name of the root folder?

Hi,

    Suppose the following folder/Obj structure:

		Zope Root
		    - test
                        showImage     (DTML Document)
		        - image
			    testImage (image object)
		    - test2
                        testProgram   (DTML Document)

    showImage contains one line of code:
       <A HREF="test"><dtml-var "image.testImage"></A> 
    that shows the testImage properly alone. But if I put
    <dtml-var "test.showImage"> in testProgram (in test2),
    I got all "<" as "&lt;" and the ugly code like the
    following was returned intead of the image with link.

&lt;A HREF=&quot;test.html&quot;&gt;&lt;dtml-var
&quot;testImg&quot;&gt;&lt;/A&gt;

    I have tried the following but none works out:
	- Use DTML Method instead of DTML Document to hold
	  showImage
	- Use "/" instead of "." to point to objects
	- Use single quote or no quote instead of double quotes

    Please advise the proper way to resolve this annoying issue.
    Thanks a lot!

Most of the unfinshed pieces have to do with giving users
propertysheets. That makes it not quite useful for PTK yet.

I'd say for non-PTK use it's in pretty good shape.  Would I recommend
using it currently? Well, for a production sight, I think maybe it's a
bit too new.  It could stand more testing and security review.  But, if
you're developing a site that you don't need to go live tomorrow, I
say sure, go for it. It's quite useable for non-PTK applications.

Sure it does! Got a SQL-based GUF? You should be able to take your GUF
userExists/userRoles/userAuthenticate/etc methods and plop them
unchanged into a LoginManager Generic User Source (GUS), and have it
Just Work. 

You're probably thinking of the comment that it's not ready to do
SQL-based PTKs. This is because the propertysheet support that PTK needs
isn't there for SQL. But, that's a feature that no other SQL-based
userfolder has anyway -- it's a new thing, and at the moment only PTK
needs it.

Sadly, the way DTML tags work right now, this isn't possible.  Since
'boundary' is part of the 'mime' tag, like 'else' is part of 'if', you can't
put it inside another tag.  The only workaround I can think of is pretty
nasty; look at the source for MIMETag and use the MimeWriter class directly.
It's not that bad, unless you don't know Python...

Urk.  First, we can pick this apart in at least two ways:

<dtml-with "PARENTS[-1]">

or

<dtml-let rootObject="PARENTS[-1]">

In either case, the part in quotes takes the last element of PARENTS, giving
you the root folder.  In the first case, we use this directly in a
"dtml-with", and can refer to properties and contents of the root folder
inside it.  In the second case, we give the root folder the local name
'rootObject' which we can then use to access it.

Evan @ digicool & 4-am

You've run into a misfeature of Python.  Since 'a' and 'b' are integers,
'a/b' is performed as an integer division.

Thus 'a/b*c' == '(3/5)*7' == '(0)*7' == '0'.  If you want floating point
division, you need to make 'a' or 'b' a float, either directly or by writing
'_.float(a)/b*c'.

Cheers,

Subject: [Zope] Version bug?
Message-ID: <38D10EEF.156ABF9E@globalcrossing.com>

Greetings!

I think I may have found a bug in the way Zope handles versions.
To recreate:

1) Set up a version, say, "TestVersion."
2) Rename the version to something else, say, "NewTestVersion."
3) This breaks the following:
   * When you enter the version, the "you are working in" line displays
     "TestVersion"
   * The "Version Management" Control Panel link shows TestVersion as
     well (this breaks the link, too)
   * Any file modified by the version shows up as TestVersion, too.

This happens on:
  Zope version: Zope 2.1.4 (binary release, python 1.5.2, linux2-x86)

Is this a bug?

Hi Zopistas,
	Thank you for the answers. My problem arose because I was passing a DTML Method a list of strings: [ 'PARENTS[-1]', 'FolderA', ...]. And while I could do:
	<dtml-with "_( folderObject=_.getitem('FolderA'))">
I could not do the same with 'PARENTS[-1]'. The simple solution suggested by your answers is to just pass the objects themselves (duh!): [ PARENTS[-1], FolderA, ...].
	But out of curiosity I'm still wondering if there is a way to refer to the root folder by name so one could write
	_.getitem( 'rootFolderName' )

Subject: [Zope] How do I set properties from DTML? (Repost)
Message-ID: <00031617290300.13146@promotor>

I'm reposting due to mail problems ...

I'm working on a thing I'll probably call "ZBox"; it's a "widget
method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Sure, you just need to trace my previous postings. :)

SyBase adapter has two specific problems that I have ran
into. They are both 100% reproduceable and both have been
reported to the Collector. One of them is now fixed for
Zope 2.1.5 (the _validTime thing.) The other one still sits
still waiting for Digicool to fix it. If I say the development
of the adapter has been slow, it's because it's been slow. If
I alone have been able to find (and fix) two problems
and one limitation, somehow I don't think they are the
only problems and limitation. :)

Some of the bugs are later found independently by other
people, too. (See below.)

Many people also say that they have zero problems with
Microsoft Windows. I guess they just have been lucky. Ha ha.
But just because one person is lucky, it doesn't mean the
rest of the world is equally lucky. :) Let me teach you
how to para-phrase your question:

"Can you provide more specific details? I am running two
separate system with Sybase, and I would like to know more
about these problems."

Very nice. The following are three articles in chronological order.

Subject: [Zope] XML-RPC Woes
References: <38D0221B.794D6C3A@wm.edu>
Message-ID: <38D129D3.B15C9835@wm.edu>

After getting a few private emails with questions about what i was doing
i thought i'd share what i'd learned and some code.

First an apology, i read through my original email and realized that i
was a bit to vague to really get any help, mainly because i don't
understand what i'm passing through xml-rpc to dtml methods that are
expecting Zope stuff (client, mapping, kw).

Second, what i'm doing. I'm creating an email archive in zope. i wrote
up some python code that retrieves/parses email from a pop3 server and
then inserts via xml-rpc into a zclass so that it can be archived and
cataloged. I got the whole thing working last night by passing the
parsed info in a dict via xml-rpc to an external method which
took care of adding the Zclasses in Zope, basically following the
example from this howto http://www.zope.org/Members/teyc/howxmlrpc

Third, How to do XML-RPC with Amos's patched xmlrpclib.py for
Authentication:
    1. Assuming you already have the original xmlrpc implementation from
pythonware.com installed, copy Amos's xmlrpclib.py over it (WARNING this
will basically delete the original).

    2. Fix the subclassing error. Find 
	class BasicAuthTransport(xmlrpclib.Transport):
	and change it to
 	class BasicAuthTransport(Transport):

    3. Fix the import error. after the comments there are some imports
add:
	from base64 import encodestring



<dtml-with Standard_Code_Disclaimer>
all code is provided on as is basis for the purpose of an example. use
at your own risk.

Fourth. External Method Code:

	def import_mail(self, props):
		id = props['id']
	mailobj=
#netscape mangles this line
self.manage_addProduct['YourProduct'].YourZClass.createInObjectManager(id,
self.REQUEST)

	mailobj.propertysheets.YourPropertySheet.manage_changeProperties(props)
	return "Zope is Cool"


this is one of those times you just look at zope and sigh. so much power
if you know how to use it. i actually got the basis of this code from
the Zope CD that they passed out at the python conference(8). this
method is part of the archive folder called below.

Fifth. The XML-RPC call: from the python script without error checking

        self.zope = xmlrpclib.Server(YourZopeServer,
                            xmlrpclib.BasicAuthTransport(userid, passwd)

        Props = {
            'Id':Whrandom.Randint(0,1000000),
            'To':Prop_list[0],
            'From':Prop_list[1],
            'Subject':Prop_list[2],
            'Date':Prop_list[3],
            'Body':Prop_list[4]
            }
        Print Self.Zope.Test_project.Archive.import_mail(Props) 


</dtml-with>


I hope this helps. if anyone has any examples of passing args to dtml
methods via xml-rpc i'd love to see them. 

Cheers,

Kapil

No, its integer :)
3/5 is 0, anything multiplicated with 0 will be 0.
so 3/5*7 is 0 no matter where you set brackets :)
Integer does not round, it only cuts off everything after the "."

Eventually you want: a=3.0, b=5.0 and c=7.0
(even only one variable beeing "float" wuld be sufficient)

so far so good. But how to I add items to the dictionary?

Okay, I *think* I am beginning to grok zclasses, but I have a couple
of questions:

What is the scope/namespace of a ZClass' methods?  In my tests, I
cannot access other methods of the same ZClass.  I *can* access
methods in parent folders of my ZClass, but not the current folder.
Ie: Create ZClass called zcTest.  Create two methods in this ZClass,
called index_html and test.  Neither can see the other.

Secondly, when I try to access anything off of instances of my zclass
except for property sheets, I get access denied.  Where do I set up
the permissions to allow my methods to be viewable?

Subject: [Zope] ZODB question, again
Message-ID: <38D13016.6F9160EC@sage.att.com>

ok, persistent fool that i am, i'm still trying to figure out
how to use ZODB in an External Method to do some simple (ha!)
database stuff.

so i built a very simple app, to implement a counter.
each time you invoke the "Count" method, you get a number
back, and it increments.

running the script (see below) by hand, it works fine.
referencing it from Zope, using this dtml fragment:

	<dtml-var "Count( 'chickens' )">

or just pointing my browser at:
http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=chickens

to reference an External Method called Count, which 
refers to the Count function in this script, i get:

   Error Type: AttributeError
   Error Value: Counter

if i then click the reload button, i get:

   Could not lock the database file. There must be another
   process that has opened the file. 

and i'm locked out until i restart zope.
can someone please help?  this is getting really
discouraging.  a simple explanation of where i'm 
going wrong would be greatly appreciated.  a small
working example of a working app would be terrific.

thanks


--------------------------------------------------------------
script follows:

import ZODB, ZODB.FileStorage
import Persistence

class Counter(Persistence.Persistent):
	"""A Persistent Counter"""
	def __init__( self, name ):
		self.name = name
		self.value = 0

def Count( name ):
	"Get counter value, then increment, creating if necessary"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/CountDB.fs' ) )
	connection = db.open()
	root = connection.root()

	if not root.has_key( name ):
		counter = Counter( name )
		root[ name ] = counter
	else:	counter = root[ name ]

	counter.value = counter.value + 1
	
	get_transaction().commit()
	connection.close()
	return counter.value

if __name__ == '__main__':

I'm able to get Zope to dump a core file if run in debug mode ('-D').  I
haven't proved this, but I suspect that when a fork()ed child dies it
does not dump a core file.  Since debug mode does not cause Zope to fork
off Zope as a child from the parent watchdog, a core file is produced. 
None of this is mentioned on the fork() man page, or the clone() man
page, or whatever.  I probably need a good UNIX programming reference to
verify it.

Give it a try, fire up Zope in debug mode and run your load scripts
against it to reproduce your segfault.

Message-ID: <4.2.2.20000316001051.00a9f710@postoffice.pacbell.net>

I am having trouble with userDB cookie authentication in IE 5 through the 
@Home network. Apparently @Home uses a proxy server for all of their 
traffic. When accessing the docLogin page for authentication the user 
receives a "Cannot Display This Page" error from IE 5. Turning off 
cookie-based authentication seems to solve the problem. This problem does 
not occur in Netscape under the same conditions and does not occur in IE 5 
when used outside of the @Home proxy.  Does anyone know of specific 
problems with IE 5 and proxy servers? Is there any solution outside of 
using standard authentication?

Try this

<dtml-var "_.float(a)/_.float(b)*_.float(c)">

You calculation is using integers and there is no automatic conversion being
done.

You need to explicitly tell zope that you want float calculations.

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:


ERROR(200) ZServer uncaptured python exception, closing channel
<zhttp_server listening :8080 at 81f5b90>

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

You cannot open the object database twice.  In this case, Zope opens it
first, and then you open it second (why you are getting the
AttributeError I don't know, a traceback there would help).

Basically what you are doing is sort-of a no-no unless you know what you
are doing.  First, a database cannot be opened twice, even from the same
process.  Second, you do not need to open the database again, because it
is already open and accessible to you from your external method:

def anExtMeth(self):
  connection = self._p_jar

All persistent objects (in this case, 'self' being the container of the
external method, probably a Folder) have an _p_jar attribute which is
their connection to the database.  Always use that instead of opening
your own.

Also, you need to be very careful with what you are doing.  You are
inserting objects right into the root level of the object database, this
is not really a good idea.  For example, let's say you fix your code to
not open the database again and you get it working.  Then (don't!) try
this URL:

http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=Application

Doh!  Guess what?  You just trampled your entire Zope, hosed the entire
enchilada, because Zope also lives in that top level namespace, and its
name is 'Application'.

Pick your own name (like GarryHodgsonApplication) and assign your
counter objects as sub-attributes of that.

Subject: [Zope] Zope Cookie Handling
Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF373@ap3expr3applge.appl.ge.com>

All,

Here is another interesting issue that I have encountered while trying to
process cookies in Zope.

On a different app. server I have a Java class which generates an encrypted
cookie when a user logs into the site.  When the user navigates over to my
Zope site, I wish to check the value of the UID.  I do this by retrieving
the cookie within the following snippet of DTML:

<dtml-if "REQUEST.cookies.has_key('UID')">
		<dtml-call "REQUEST.set('cookie',
REQUEST.cookies.values())">
		<dtml-var "validateCookie(REQUEST, REQUEST['REMOTE_ADDR'])">
</dtml-if>	

This DTML calls a DTML method (validateCookie) which in turn is calling the
following External Python Method:

import xmlrpclib, base64

def validateUID(self, REQUEST, ipaddr):
        cookie = REQUEST.get('cookie')
        servlet =
xmlrpclib.Server("http://salesnet-dev.appl.ge.com/geaservlet/X
mlRpcTest")
        cookie = repr(cookie)
        cookie = cookie[2:]
        cookie = cookie[:-2]
        return servlet.validateCookie.check(cookie, ipaddr) 

This XML-RPC call attempts to invoke the Java decrypt method.  Herein lies
the problem:

Upon investigation of the value contained in the UID cookie, Zope returned
the following:
\316\313\321\310\316\315\314\311\321\312\316\317\317\223\310\321\315\317\313
\316\317'

If I print out each character created during the Java encrypt method, the
following values are returned:

\206\203\209\200\etc.etc.

A colleague of mine pointed out that Zope was returning the values in Octal
rather than decimal.

Is this behavior by design?  Is there another mechanism I can use to
retrieve the raw cookie value before Zope places it in a dictionary?  Rather
than code a string parsing routine in Java, are there any suggestions as to
how to convert each character back to decimal, or obtain the string prior to
being converted into octal?

Once again, I appreciate the assistance/responses.  Everyone on this group
has been wonderful to interact with.

-Brian

This apears to be fixed in the CVS.  The reason is dispatcher.accept may
return None if the accept() sys call returns EWOULDBLOCK.

Assignment cannot be done in DTML, it is a security risk.  DTML was not
designed to be a general purpose programming language; it's meant to be
a reporting language.  Use python (either external methods or
PythonMethods) if you want to do this.

Subject: [Zope] Problem with ZODBCDA
Message-ID: <38B478360010B51B@smtp.visto.com> (added by administrator@visto.com)

I just installed ZODBCDA on a new Windows install of Zope 2.1.4 using ZServer running as an NT service.  After editing db.py to fix the THUNK typo (I've submitted that to the collector) it sees the System ODBC DSNs that exist, and it lets me pick one.  But when I try to open the connection, it tells me I have an invalid connect string.  The weird thing is that I turned on Windows ODBC tracing, and NOTHING is being logged from the Zope connection.  So I don't think it is actually passing anything to ODBC.  If I do the same thing from some other ODBC client, the connect string works and the session gets logged by the ODBS tracer.

There was a very similar problem in the list archives several months ago, and it seemed that running the service as a user, instead of the system, fixed the problem.  Didn't work for me.

Any suggestions on how to track this down further, or better yet to fix it, would be appreciated.

Message-ID: <38B478360010BA29@smtp.visto.com> (added by administrator@visto.com)

Within the last half-hour I posted that ZODBCDA connections were not working correctly on my machine, with Zope running as an NT service.

I rebooted the computer and now the connection gets made. (I hadn't rebooted since I changed the user the service was supposed to be running as.)  So with the Zope service running as me, rather than as the system, it seems fine.
And now my problem is exactly the same as the one in the archives last year.  This doesn't seem too serious, but if anyone knows why it cares who Zope is running as, I'd still like to know.

Thanks,

Fortunately MySQL has transactions high up on the todo list (but it's

Zope doesn't do anything above and beyond what python does.

Python rounds integers, quite simply:

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> 1/2
0
>>> 3/5*7
0
>>> (3/5)*7
0
>>> 3/(5*7)
0
>>> 

integers as input gives an integer as output.  Obviously there are two
schools of thought on this.  If you want a floating point number, use
'float()' (or in DTML, _.float())

>>> float(1)/float(2)
0.5
>>>

<dtml-with "PARENTS[-1]">
	<dtml-var rootProperty>
</dtml-with>

should do the trick - although you have access to rootProperty in any case
because of acquisition:

<dtml-var rootProperty>

Uups, sorry

<dtml-var "test.showImage(_.None, _)">
           ^^^^^^^^^^^^^^ 

but i think you have to call also

<A HREF="test"><dtml-var "image.testImage()"></A>

How can I access this database through ZOPE.

When I try to make the MySQLDA extension a lot of errors come out of it
:

Can you help me ?


Does DigitalCreation have a solution on connecting to MySQL on a Linux
Platform (thanks to ODBC or something else).

Thanks in advance.

You have to convert it from integer to float. Try:

<dtml-var "(_.float(a)/b)*c"> 

Though you're rigth, you need the parenthesis for the correct
evaluation.

Hello there

I' ve got some difficulties with the very final step of ZOPE-Installation:
I made the start-script as root (-> python wo_pcgi.py) and got all the neccessary scripts. Then I chown and chgrp all files to my ZOPE-user and tried to start up the server. Unfortunately the script has got some endless-loop or so and I have to break (Ctrl-C) in order to get my prompt and logout. I do have access to the server via WWW but only until I break the script. 

Do you know some hint?
Thank you very much!

The root folder can indeed be accessed by PARENTS[-1].

<dtml-with "PARENTS[-1]">

is all you need.

Keep in mind also that if the property of the root folder you're trying to
get at has a unique name, you can get to it via acquisition. (If the
property is called "foo", <dtml-var foo> would look up the property and find
it, all the way at the root.)

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

Your properties look like integers, and I believe that is your problem. Try
this:

<dtml-var "_.float(a)/b*c">

By converting a to a float and then doing the rest of the expression, python
should consider the whole expression to be floating point.

Subject: [Zope] BIG ZODB - Scalability
Message-ID: <E12Vac2-0001CF-00@home.delysid.org>

Hi.

I just got the job to find out how we (the technical university Graz)
could build up a large image-database for different users..
Zope came to my mind because of its oject oriented structure.
And because I'd really like to do Zope work at work :).

I now have to find out how Zope can be used with really large
databases.
(100000 to 1mio objects theoretically in the future).

Can anyone provide me with URLs or information on:
The relational Database Storage Manager (couldnt find any references)
  (is this intented for large databases?)
Or splitting the Zope hirarchy into multiple ZODB FileStorage Manager
instances. SO that I could e.g. save on subfolder of the root folder
in on data.fs and the next subfolder in another data.fs

I am thinking of the filesize limit of some operating systems.
2GB isnt really much.

I think that a FileStorage would be better for our content (images),
because performance issues (never saved 20GB in an relational database before :) )

Any help is appreciated,

There are three errors here :-)

First, Python atribution doesn't return the value like C. The
value of "myObject = 1" is None.

Second, as you said, 'PARENTS[-1]' is not an object. Using
_.getitem Zope will look for an object with this name, which
doesn't exist.

Third, there is absolutely no reason for the _.getitem.

What you want can be acomplished with:

<dtml-with "PARENTS[-1]">
   ...
</dtml-with>

or

<dtml-let rootObject="PARENTS[-1]">
   ...
</dtml-let>

depending on what it is you want. :-)


Also note that if you're using SiteAccess' virtual hosting,
PARENTS[-1] will (IIRC) not give you the root folder, but the
virtual root.

testProgram should *call* the showImage method, otherwise you just insert a
string representation of it.

<dtml-var "test.showImage(_.None, _)">

Thanks, I've never accessed the CVS. How soon might the fix show up in a
release? (Or is there a simple change I can make to one of the .py files
until that happens?)

I would implement this whole thing as a Python product and avoid mucking around
directly with the persistence machinery altogether. This would allow you to add
a Counter object anywhere in the Zope tree.

import OFS, Persistence

class Counter(OFS.SimpleItem.Item, Persistence.Persistent):

    def __init__(self, id, title):
        self.id = id
        self.title = title
        self.counters = {}

    def Count(self, name):
        if not self.counters.has_key(name):
            self.counters[name] = 0
        v = self.counters[name] + 1
        self.counters[name] = v
        return v

manage_addCounterForm=HTMLFile('methodAdd', globals())

def manage_addCounter(self, id, title, REQUEST=None):
    ob = Counter(id, title)
    self._setObject(id, ob)
    return self.manage_main(self, REQUEST)


Add a Counter call 'counter' to a folder, then call:

<dtml-var "counter.Count('chickens')">

Subject: [Zope] New LocalFS Release
Message-ID: <03f001bf8f8f$4dcdee20$eb0217ac@dev.prognet.com>

Version 0.1.6 of LocalFS is out. I'm calling this one the Ides of March
release. :)

New in v0.1.6:

 - Fixed a bug with filtering in directory browse view.

 - Fixed bogus text/html content-type on non-HTML files.

 - Use a more aggressive search to determine whether files are 
   binary or text. This causes directory browsing to take a bit 
   longer but hopefully prevents file corruption problems.

 - Added a Properties tab which allows specifying custom properties.

 - Improved the formatting of directory browse view again with tables.

 - Convert .xml files to XMLDocument objects if the XMLDocument 
   product is installed.

 - Convert .stx files to StructuredDocument objects if the 
   StructuredDocument product is installed.


In 0.1.7 I'm adding fully-customizable mapping of file extensions to
content-types, Zope object classes, and icons in the directory browse view.
Hopefully that should be out pretty soon as well.

<dtml-if "_.string.find(ua,'MSIE') != -1">
 <dtml-comment>

  <dtml-call "REQUEST.set('iMSIE4',_.None)">
 </dtml-if>

  <dtml-call "REQUEST.set('bMSIE4',1)">

  <dtml-call "REQUEST.set('minorVer',ua[iMSIE4+8])">
  <dtml-if bMSIE4>
   <dtml-if "minorVer == 'p' or minorVer == 'b'">
    <dtml-call "REQUEST.set('bMSIE4_beta',1)">
   </dtml-if>
   <dtml-if "minorVer == '1'">
    <dtml-call "REQUEST.set('bMSIE4_01',1)">
   </dtml-if>
  </dtml-if>
 </dtml-if>
 <dtml-if "_.string.find(ua,'MSIE 5') != -1">
  <dtml-call "REQUEST.set('bMSIE5',1)">
 </dtml-if>
<dtml-else>
 <dtml-comment>
  Let's assume netscape
 </dtml-comment>
 <dtml-call "REQUEST.set('bNetscape',1)">
 <dtml-if "ua[8] >= '4'">
  <dtml-call "REQUEST.set('bNetscape_4',1)">
 <dtml-elif "ua[8] >= '3'">

 <dtml-else>
  <dtml-call "REQUEST.set('bNetscape_2',1)">
 </dtml-if>
</dtml-if>


Include this in your standard_html_header and then use the variables in your
pages as normal,so:

<dtml-if bNetscape_4>
  do netscape specific stuff
<dtml-elif bMSIE4_01>
  do IE specific stuff
</dtml-if>

Hello Olivier,

Thank you for your help. The call to the method seems ok, but the code
of the method is displayed instead of been executed. May be is it a
code for external method ? Other things to do instead copying the code
to the DTML method code window in the Zope interface ?

Anyway, could someone please post an exemple of an DTML method
accepting parameters - that is the code to put in the proper windows
in the Zope interface - or a pointer to a document explaining how to
proceed ?

Thanks in advance,
Greetings,
Eric

I don't know.  Further, I'm not sure if the fix is in the 2.1 branch. 
Possibly not, so you'll have to wait until 2.2 which has no release data
set and will probably go through a thorough beta period.

Not really.  Check out the zope site under Resources and read the
instructions on how to check out code from the CVS.  You could probably
get away with replacing your ZServer/medusa directory with the CVS
version, but don't be suprised if that doesn't work.  In fact, if you
aren't confident about that or don't know how to use cvs or don't know
python, I don't recommend you do that at all.

Subject: [Zope] Subclassing ZObjectManager in ZClasses
Message-ID: <4.2.0.58.20000316233055.0163ae70@192.168.0.2>

[Repost - previous message was truncated.]


Hello,


I've been playing with ZClasses and I ran into an issue with ZObjectManager.

Summary: (when creating a folderish ZClass and cascading base classes) if 
ZObjectManager isn't subclassed at 1st level, objects can be added to the 
folderish ZClass instances but they don't show in the manage_main object list.

[Zope 2.1.4 on Win32, pure ZClasses, no Python around]

More details:

1) I first tried this simple setup. It worked fine:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyTestClass

MyTestClass is folderish and works as expected.


2) This setup worked fine too:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyBaseClass
     |_MyTestClass1
     |_MyTestClass2

I can create a custom base class and use it in several ZClasses. They are 
folderish and work as expected.


3) Then I tried this setup:

ZClass_for_CatalogAware
ZClass_for_Renderable
   |
   |_MyBaseClass
   |_ZObjectManager
      |_MyTestClass

Here I first created MyBaseClass, then I subclassed it together with 
ZObjectManager when creating MyTestClass.

MyTestClass looked OK; I created a Content view linked to manage_main; I 
allowed adding standard object types such as Folder and File.

However, when I add objects in an instance of MyTestClass they do not show 
in the object list (Content view). I *think* they are actually added 
because I cannot add an additional one with the same ID: I get an "ID 
already in use" error.

When testing further I got the same results when CatalogAware and 
Renderable were not around. Same results too when subclassing Folder instead.

It's not that bad, but I can't create a standard base class, then use it to 
create a folderish variant.

Does anyone understand why?


Cheers.

Alexandre

Your pattern is ^/Zope/(.*).  The ^ means match the beginning of the
'script path'.  So, this pattern will match:

http://www.test.net/Zope/

Keep in mind this will NOT match http://www.test.net/Zope (without a
terminating /).  If you want to match:

http://www.test.net/

The use the pattern ^/(.*)

You many need to play with the initial /s a bit.  Various versions of
mod_rewrite have done this different ways, some versions match ^ up to
the first /, and some don't.

Do note the rewrite documentation at 
http://www.apache.org/docs/mod/mod_rewrite.html

``The great thing about mod_rewrite is it gives you all the
configurability and flexibility of Sendmail. The downside to mod_rewrite
is that it gives you all the configurability and flexibility of
Sendmail.''

Message-ID: <20000317004314.A1830@owl.rhein-zeitung.de>

Hi,

I am currently developing a new product for my company using Zope. No I am
running into a problem. I like to use the building user management and user
auth features, but I also need add to some new properties to a user record.
Nothing big just a few properties, that a relevant for some user specific
configuration parameters.

Can I add new properties to an User object, or do I have to create a new
UserFolder and new User object using ZClasses? The later wouldn't be very
satisfying. Or can I just create my own type of user and add it to any user
folder? Especially the buildin user folder of Zope?

Bye, Oliver Andrich

If you're using the 'start' script, background it:

Has anyone else seen this type of message.  We've been assuming they are
simply people hitting the stop button on the browser thus terminating

The Z SQL Methods User's Guide

This shows you everything you need to know to do things the Zope way. It assumes
you have a basic understanding of HTML forms and the SQL language.

I have gone a little bit down the road toward a design for this:

  http://www.zope.org/Members/tseaver/CosNaming

I also have some hackish code on my local box which exercises a tiny portion of
the design.  The code is too ugly to release, but I do hope to be working on it
over the next few weeks.  There are a couple of other folks on the list
interested in CORBA as well -- I'll CC them in case they have gotten further off
the dime than I have, and would therefore be able to bump your comfort factor up
a bit higher.  Perhaps we should set up another list for this topic?

There is a special piece of syntactic sugar for one-based numbering::

  <dtml-in "_.range(x)">
    <option><dtml-var sequence-number></option><br>
  </dtml-in>

(See $ZOPE_HOME/lib/python/DocumentTemplate/DT_InSV.py for more grubby details).

Subject: [Zope] External Methods and REQUEST
Message-ID: <38D1A522.E70421A6@picknowl.com.au>

Greetings,

I've started having a serious fiddle with External Methods, and have
run across a couple of brain issues:

1)  Most examples I've seen (well, both :-) pass REQUEST as a parameter
in addition to self (for example, def frobnicate(self, REQUEST)).  Yet
I've noticed that I can pull REQUEST out of self's namespace, and they
appear identical.  Is there a reason for passing in REQUEST explicitly?

2)  (And if this is related to point #1, then you may beat me around the
head with a Nerf bat).  I defined an external method called frobnicate
as follows:

def frobnicate(self):
    "One of many test functions"
    return self.REQUEST.form

and install it.  If I call it with http://localhost/zope/frobnicate?foo=bar
it returns a dictionary of {'foo' : 'bar'}, as it should.  If I call
it without any arguments as http://localhost/zope/frobnicate the
browser hangs and eventually times out with "The document contained no
data".  I'm specifically interested in form data here, which is why I
haven't used the REQUEST['thingo'] idiom, so I suspect I must be
accessing REQUEST incorrectly.  Any clues would be most welcome (if
only someone could write a ZenOfZope product; I'd download it into my
brain in an instant! :-)

  Daryl Tester

Overview

I am trying to put an XML structure into a Zope product that mirrors the=
 hierarchy.

The dtd for the XML is roughly of the form
<!ELEMENT nodes (node)*>
<!ELEMENT node (node|leaf)*>
<!ELEMENT leaf (object)*>
<!ELEMENT object EMPTY> 

The 4 elements share several attributes and each has some unique=
 attributes. So the intent is to group the common attributes in a couple of=
 property pages and create an property page for each individual element.

The desired ZClass representation is as follows:
container (object manager)
    base () {to contain common property pages}
    nodes (object manager, base)
        node (object manager, base)
            leaf (object manager, base)
                 object()

I build the hierarchy, set permissions as follows and do the factory edit=
 button trick
container - add_nodes
nodes - add_node
node - add_node, add_twigs
twigs - add_objects

I instantiate a container, 
add a nodes object to the container, 
add a node to th nodes.

At this point I can only add twigs though I think I should be able to add=
 nodes. I thought I would look at the SubOjbects list however the only=
 object that appears in the Subobjects list is nodes.

Am I missing something here? I have tried countless permutations with and=
 without the base class, deriving base from object manager etc... I think=
 one of my prior iterations actually worked but without the base class=
 concept though I seem unable to reproduce it now...

Does anyone have any ideas?

Thanks 
Bob

I am not sure what is going on but wouldn't it be generally safer if your
java class converts the encrypted cookie in some ASCII text format first?
I think that will solve your Zope problem too.

In general the process is:

- create a database adapter
- create a zsql method to do the insert
- create an html form to submit the data
- create a dtml method to call the zsql method as the form's submit action

Here's a pretty good how-to that describes the entire process in detail.

I find these pages to be an essential reference for zsql:

Hi Jeff.

Can you post the traceback. If this is the error I think it is then it may be
related to what you set as your SMTP server when you created the WorldPilot
object. One thing I found that works reliably is to specify   localhost  for
the SMTP and IMAP servers. 

BTW which IMAP server are you running? and what is your SMTP server?

Good Luck!

Being explicit.  Also, your method might not (depending on how you use
it) be being called from ZPublisher (in which case REQUEST is not
passed, it must be acquired), then again, your method might not be in an
acquisition context either, in which case you must pass it.  In 99% of
the cases however, you can do either.

Well, hanging is probably not the best way for Zope to handle this
situation, why it hangs I couldn't tell you (perhaps you should post
that to the collector).  However, form data usualy comes from a POST,
and here your doing a GET, passing a query string.

You can still get form data that way, the form attribute of REQUEST is
when you want to make sure you're definatly getting a value from a form
and not some other namespace.

I went ahead and wrote a Java helper class to convert from base 8 to base
10.  This has resolved the problem.  For those interested:

private static String convert(String uid)
	{
		
		StringBuffer sb = new StringBuffer();
		StringTokenizer octalString = new StringTokenizer(uid, "\\",
false);
		Integer convert = new Integer(1);

		while(octalString.hasMoreTokens())
		{
	
sb.append((char)convert.parseInt(octalString.nextToken(), 8));

		}	
		return(sb.toString());
	}

I am still curious as to why Zope converts the data into base 8.

Thanks for your response.

I keep forgetting that Zope is a collection of products :-(.  One day,
I do intend to spend more quality time with the source and how the
components interact.

Oddly, it only appears to do that when I call the external method
directly.  If I place <dtml-var "frobnicate(REQUEST)"> (modified to
pass in REQUEST explicitly) into a Method or Document and request
that without parameters, it comes up immediately and correctly.
Odd.

Will do.

Ahh, differing semantics.  I'm used to Python's cgi.py (and Perl's
cgi.pm, from memory) treating POSTs and GETs with query strings
the same.  The only way of telling the difference was by looking
at the REQUEST_METHOD (if you cared enough, that is).

This was my concern - REQUEST's namespace seems a little crowded, and I
was worried about clashing identifiers.

Hold the phone!  I've just constructed a document that basically does
<dtml-var REQUEST>, and invoked it with a query string, and the
parameters DO show up in REQUEST.form.  Are you pulling the wool over
my eyes, Michel?  :-)

Regards,
  Daryl Tester

PS - The recent "Virtual folders / URL" thread solution you proposed
was _very_ enlightening, but yet reading about direct traversal in
the ZSQL manual didn't provide anywhere near the same lightbulb factor.
Could Digital Creations consider adding that in as an example?

Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF372@ap3expr3applge.appl.ge.com>

All,

Have been trying to add File Attachment functionality to the ZDiscussions
Product.  Thus far, I have modded the ZDiscussions.py file, specifically the
ZDItem class's __init__ method, to accept one extra parameter called file.
The corresponding DTML-Method (postForm) within the ZDiscussion object has
been modded to include a FILE input field.

To facilitate the file handling, I am using the Squishfile.py module.  All
is working well, and via a new def attachment(self) method that was added to
the ZDiscussion.py module, I am able to return the file to the browser.

Herein lies the problem.  How can I reference the file via an HREF?  With
the following DTML:

<dtml-if attachment> 
	<b>Hello there</B>
	<tr><th bgcolor="#d0d0f0" align=left>Attachment:</th><td>
	<dtml-in attachment>		
		<A HREF="./<dtml-var file_name url_quote>">  
		<IMG SRC="<dtml-var SCRIPT_NAME >/<dtml-var icon >"
HEIGHT=16  
		  WIDTH=16 BORDER="0" ALT="Click to download
attachment"></A>    
		<A HREF="./<dtml-var file_name url_quote>">  
		<dtml-var file_name></A>   
		<dtml-var file_kbytes>KB (<dtml-var file_bytes> bytes)<BR>  
	</dtml-in attachment></td>
</dtml-if>

This of course references the file object as
absolute_url/ZDItem_id/file_name.  This same reference url is used in the
Squishdot product when displaying a link the user may click on to download
the file.  However, in my implementation it is not referencing the file.

The only way to reference the file is to use <dtml-var attachment>, which
means that the file will be streamed to the user as soon as they click on
the message thread, obviously not the way I would like to handle the
situation.

Do I need to include the file object as a property of the message?  I
thought by including the file object during the creation (__init__) method
of ZDItem this would be handled.

Any/all assistance would be greatly appreciated.  Also, if I am crazy for
doing this please let me know.  Perhaps a new ZDiscussion already exists
that supports attachments?

Thanks again,
-Brian

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,

Michael Bernstein.

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,


[RH]Michael,

What you seem to be descibing is some sort of an internal Zope 'link base'
as they exist for may hypertext systems (but zopish). This would be very
useful.
I do have some doubts about your desciption, however:

- would the generic relationships (meta-type<->meta-type) you describe be
the best way to go and whether they would turn out to be very useful. You
also do not mention one-to-one relationships; I'm sure this is not on
purpose, but this could be implemented quite simply by a specific python
product.

- I also wonder whether much of what you describe cannot also be achieved in
other ways, mainly through using the Catalog (as you indicated yourself). If
I may speculate a bit more on this point: what you want may be a specialized
folder index method that uses a mix of its own objectValues and Catalog
obtained objectvalues for its contents. If you wanted to use symlink type
relations, this may be done by using properties (this is more or less
generic) or by using the values of a 'link base' type of object (see above).
THis last would be very specific: pointing to specific objects.

- The idea of relationship aware is nice, but the drawback is that it can
only be true for derived ZClasses, and not all zope objects are Zclasses.

- In ZDP list many of these subjects have been in question for some time
now. You may want to have a look at the list archives of last month for many
of the discussions and of course the implementation of ZDP Tools by Maik
Roeder (available somewhere from his member page:
http://www.zope.org/Members/roeder)

Hi,

Wasn't it generally agreed that storing a counter in a ZODB was a bad idea 'cos of the high number
of refreshes, and hence the number of transactions stored in DB?

Basically, because of the undo/rollback capability of ZODB, the data.fs grows rapidly if you use it
to do counter-type things.

Or an I wrong?

I am using Zope for an large  project at the moment. For static content, 
such as images, I use apache to server them up (and will probably move
to something faster such as thttpd or kernel mode http server) and then just store
a URL reference to the actual data. This leaves zope to do presenatation, which it
does really  well and let a more suitable server handle the static content.
Any way, I'm not saying that zope couldn't handle this however depending on
 your exact use this may be an option for you.

Cheers,

Benno

You can help yourself by consulting the archives of this mailing
list:

The solution is to patch MySQLmodule.c to make it compliant with
mysql.h of newer versions of MySQL.

You can find my (unofficial) patch in the archives of the mailing

DTML-LET is meant for renaming expressions, like a macro

      <dtml-let name="bob"
                relation="uncle">
        <dtml-var name> is your <dtml-var relation>
      </dtml-let>

what actually gets evaluated is <dtml-var "bob"> is your <dtml-var "uncle">,
which is nice.


the other part <dtml-let x=5 y=7>

is rewritten to <dtml-var 5><dtml-var 7>

which is not nice at all as there is no variables called 5 and 7.

OTOH 

      <dtml-let x="5" y="7">
        <dtml-var x><dtml-var y>
      </dtml-let>

should run fine as then x and y are expressions and not variables 
so 
<dtml-var x><dtml-var y> is <dtml-var "5"><dtml-var "7"> which runs fine.

Subject: [Zope] security question
Message-ID: <001401bf900d$0e049860$1464a8c0@sabine>

hello:

for my zope, the root directory is protected so that anonymous users have no
permissions.  in addition to root, two other users are defined and given the
role 'internal'.  one of the users has a username/password.  the other
allows access based upon IP range.  this works as intended.

i now want to give anonymous users permission to access
/subfolder/index_html.  this dtml method accesses a database and uses
LocalFS.

my first attempt to realize this was to assign the appropriate permissions
to Anonymous for index_html.  when this failed, i went to the /subfolder
security and modified permissions there that seemed relevant.  i tried many
combinations until finally giving up and granting all available permissions
to Anonymous at the /subfolder and /subfolder/index_html levels.  so now,
all permissions are checked for 'acquire' and for 'Anonymous'.

even this does not work!  users attempting to access
http://myzope/subfolder/index_html are greeted with an authentication
dialog.

so, despite the fact that security seems to be a pretty simple concept i
seem to be missing something fundamental.

any insight would be appreciated.

thanks,
bac

Security is never a simple concept, especially in system as complex as Zope.

Some decent documentation would help ;-)

Stupid bug :-)
here is the patch against
lib/python/Products/jcNTUserFolder/NTUserFolder.py:

164a165
>         userobjects = filter(None, userobjects)


if you don't have patch.exe (which is likely to be the case, as you run Zope
on Windows...), the above patch means that you have to add the line
userobjects = filter(None, userobjects) at line 165 of the file so the code:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        return userobjects

is turned into:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        userobjects = filter(None, userobjects)
        return userobjects

You could also download the latest jcNTUserFolder-0.0.4 at
http://www.zope.org/Members/jephte/jcNTUserFolder

Remember: Zope must run as a service or the user have "act as part of the
operating system" for jcNTUserFolder to work!

[I'm posting this again because, suprisingly, there was no response]


I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute)?

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

I would add to this that Relationship objects, or rather the unnamed
sub-objects which actually hold the data for individual pairings, should
have properties in their own right.  A relationship (especially many-to-many
type) can have information associated with it which properly belongs to
neither of the related objects, such as 'advance amount' for an Author
relationship.

It isn't clear to me that Relationships is really the right way to do this,
but if someone wanted to code it I'm sure people would try it out.

I'm guessing that Steffen is using the "default" start script, which passes the
"-D" parameter to Zope -- it is therefore running in "debug mode", and writing
error messages to the console.  Backgrounding it will work, sort of, but will
leave Zope expecting to write to the controlling tty -- if it goes away (i.e.,
Steffen logs out), then Zope will die hard when trying to write to it.

A better fix is to edit the start script and remove the "-D" from the command
line.  Without the "-D", Zope will daemonize itself, and the backgrounding won't
be needed.

Message-ID: <4.2.0.58.20000317180935.00c97e80@195.60.12.162>

I'm trying to build up some variables from more than one form which are to 
be inserted into an SQL table. THe problem is that as soon as I call the 
second form the existing FORM variables in the REQUEST are lost. I've tried 
saving them in a SESSION variable using SQL Session (I can save them OK) 
but then of course I have to get them back into something which an SQL 
Method can understand. I'm stuck at this point.

Is there any way to pass the SESSION variable into an SQL Method ??

Or, if not, How do I get the values back from SESSION so that I can call an 
SQL Method ?

Many thanks in advance

No, it is not supposed to be in the list. Zope is not SSI, nor does it try
to be SSI compatable. Zope does have analogous variables, though. For
example, when I navigate to http://my.server.com/jeff/dumpRequest, I get:

  URL0 = http://my.server.com/jeff/dumpRequest
  URL1 = http://my.server.com/jeff
  URL2 = http://my.server.com

  BASE0 = http://my.server.com
  BASE1 = http://my.server.com
  BASE2 = http://my.server.com/jeff
  BASE3 = http://my.server.com/jeff/dumpRequest

  PATH_INFO = /jeff/dumpRequest
  PATH_TRANSLATED = /jeff/dumpRequest

Since I haven't done much with SSI in the past, I don't know which one is
similiar to REQUEST_URI. If I had to guess, I would say PATH_INFO is the
one you are looking for.

Try this:

<A
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80&dtml-PATH_INFO;;weblint">Link
Text</A>

or,

<A href="http://validator.w3.org/check?uri=&dtml-URL0;;weblint">Link
Text</A>

Obviously, the second is preferred, since it is both more clear and
requires less maintenance (the URL is not hardcoded, so if your server
changes from dnrdb.cbi.tamucc.edu to newserver.cbi.tamucc.edu, the code
would not require change.)

Hope this helps.

Zope is, it's default storage, FileStorage, is not.

Yes.

Well, that question can't really be answered.  First off, there is a
global python interpreter lock.  I don't really want to get into the
details here, but basicly only one thread of execution can be in the
interpreter at once.  This is a pretty major limitation in Python's most
popular implementation, CPython (which is what Zope is based on).

The interpreter will 'give up the lock' every N bytecodes or so, there
is some mechanism for you to control this.  Check the python site for
more details.

Your idea is not bad, as long as you use a Storage that is multi-process
safe like ZEO.  I'm not sure if having as many Zope instances as Apache
instances is necessarily a good idea, since Zope instances can become
huge, many times bigger than their Apache counterparts.  Given Apache's
nature to do lots of forking and pre-forking (yes, this can be
controlled) this might lead to immense memory requirements.

Besides the AUTHORIZED_USER field in the http header what else does zope use to identify
an http packet from a browser ?.  I am just wondering can I not masquerade as a user by setting 
the http header using httplib or some such utility ?. I have not seen any session ids in the REQUEST
variable which is supposed to contain all the variables in the browser request

Values like this that you are looking for come from the front end web
server.  Most web servers pass a number of these variables into the
environment of a program that they are executing (in this case, Zope). 
The specification of what variables gets passed and how is called Common
Gateway Interface (CGI).

REQUEST_URI is not part of the CGI/1.1 (the most recent) spec.  I
suspect you are used to programming in some sort of SSI environment
where REQUEST_URI exists as a convienience for programmers.  I do
believe I recall REQUEST_URI being a variable in Apache.  This
convienience does not exist for Zope because it is not a standard CGI
variable and Apache does not pass it to Zope or any other CGI program. 
There is, in fact, probably some other standard variable that does the
exact same thing as REQUEST_URI.

The list of standard variable can be found at:

Subject: [Zope] Odd AttributeError (__call__)
Message-ID: <38D294FE.357B2DA4@harlan.frohwitter.com>

I have three instances of Zope running on three different machines (all
dual PPro).  On the first two machines, a simple <a
href="otherfolder">Click here to move to the other folder</a> works just
fine to hyperlink to the index_html in the "otherfolder" folder. 
However, on the third machine (ironically the one that I want to deploy
to) the same hyperlink encounters the following error:


           
           Zope Error

           Zope has encountered an error while publishing this resource. 

           Error Type: AttributeError
           Error Value: __call__



In all three instances, the security is set up the same way on all
documents, images, and folders accessed.  Incidentally, the deploy
server and one of the working ones are running Zope 2.1.4.  The other
working one is running 2.1.3.  Does anyone have an idea what my problem
is?

Thanks in advance,

Ron

AUTHENTICATED_USER is an object created after a client authenticates, it
is not an http header nor is it derived from the Authentication header. 
The Authentication header contains a user id and base64 encoded password
that is used to authenticate the client.

I assume by 'packet' you mean request.  HTTP is stream based.

No.  You can authenticate yourself with such a client, but you must
still have a valid password.  You cannot just insert any old user id
into the Authentication header and expect Zope to believe you.  That
wouldn't exactly be very good security.

Message-ID: <613145F79272D211914B0020AFF6401914DE7D@gandalf.digicool.com>

Hi all,

Zope 2.1.5 has been released - you can download it from
the usual place on Zope.org:

http://www.zope.org/Products/Zope/2.1.5/


This release fixes two fairly important security issues 
that have recently come to our attention:

  o It was possible for a Zope user with a fair amount of Zope 
    zen and permission to create DTML documents and Folders
    to circumvent the security machinery within DTML in certain 
    situations, possibly giving the user the ability to use 
    resources that he wouldn't otherwise be able to access via 
    DTML.

  o It also came to our attention that the DTML code in 
    ZSQLMethod objects was not subject to the same security
    constraints as the DTML code in DTMLMethods and DTML 
    Documents.

The 2.1.5 release fixes both of these issues and we highly 
recommend that you upgrade, especially if you use Zope for 
sites that allow untrusted users to create Folders and DTML 
Documents or DTML Methods.

The release also includes a number of recent bug fixes, 
including the problem in TimeStamp objects that caused 
the bobobase_modification_time() of Zope objects to 
appear to be a day behind. Note that this release contains
two binary changes, so those running Zope from the source 
release will need to rebuild the Zope extensions after 
applying the update. The fixes are also available in CVS 
and binaries will need to be rebuilt after the update for 
those of you using CVS.

Note that with the 2.1.5 release we will also be releasing
"diff" updates as .tgz files that will let you easily 
upgrade an existing 2.1.x site. These updates are available 
for those currently using the 2.1.x source release or the
2.1.x binary releases for either solaris or linux (diff 
releases are not available for win32 for now).

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

As far as authorization goes, I've noticed that I get prompted for a
user-name/password only once during a session.  After you've been validated, it
appears zope does not prompt you again for that browser session.

The reason I'm concerned is that if I have to do maintenance on someone else's
web browser, how do I ensure that after I leave a person cannot use the back
button or history list to gain manager access to the site?  Do I have to exit
the browser when I'm done?

Daniel,

THis is a limitation of HTTP basic authentication and is not a
Zope-specific problem.

Either quit the browser before you leave or write a short dtml method:

<dtml-raise Unauthorized>
Logout
</dtml-raise>

and call it before you leave.  Note that you need to call it, then click
"OK", or you will still be logged in.

Actually Zope does prompt your client on every single request (that
requires authorization), it must, because HTTP is stateless.  Zope also
validates every single request.

This is a 'feature' of the HTTP Basic Authentication spec that says
browsers can cache auth information.  It is however often a lack that
browsers do not let you manually clear this cache.

Yes.  Or force the client to discard it's cached auth info with a
<dtml-raise Unauthorized></dtml-raise>.

Yes, you can nest dtml-in's and you pass the parameters to the SQL
method by explicitly invoking it as an expression, not just as a
name.  (It happens that I asked a very similar question of this list
recently, which is why I now know the answers.)  My example, stripped
down a bit, looks like

<dtml-var standard_html_header>
<dtml-in search_author size=50 start=query_start>
  ...
        <tr>
          <td class="center"><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
          <td><dtml-in expr="return_authors(seq=seq)">
                  <dtml-var name>;
              </dtml-in></td>
        </tr>
 ...
</dtml-in>

I hope this is enough to get you started.  Contact me directly if you
would like more explanation.

Yes. Assuming that you're using basic HTTP authentication, restarting the
browser will clear everything out.

The key to figuring this behavior out is understanding how ZPublisher maps
a URL:

 * Split the URI path into a sequence of names

 * From the root, traverse each named object in order (allowing
   it to intercept the traversal, if it wants).  Traversal requires at
   least minimal permissions on the traversed-through object.

 * During traversal, allow the acquisition machinery to operate

 * If the last item traversed to is callable, call it;  otherwise, render
   it.

This works somewhat like permissions on a Unix directory:  you have to have the
executable bit set in order to traverse the directory, and the read bit set in
order to list it.

Hope this helps!

 Thanks.  I would think then this password is succeptible to the same pitfalls
as  sending clear text passwords over  the network which can be stolen. In
which case making users to use https is a good idea ?

Yeah this is probably the best idea. Zope sits

Message-ID: <Pine.LNX.4.10.10003172246500.10594-100000@yoni.northernwastes.org>

So...

I'm sure the answer to this question is painfully obvious, but I've
pounded on the docs and I can't find it for the life of me.

I have created a subclass as per the instuctions in the Zope Developers
Guide.  I am doing this specificly to avoid my inner class polluting the
global product list.  (There will ulimately be a large number of these
inner classes if I can figure this out.)

So far, so good.  Using the dtml-var tag I can display any property of any
instance of my newly created subclass.  But I also need to build a table
that iterates though all instances of this subclass and displays several
of it's properties.

I suspect this involves the use of the dtml-in tag, but I can't for the
life of me figure out what the syntax should look like.  The discussion of
dtml-in tag seems to imply a list of objects in a folder, and what I have
is a list of subobjects in an object.

Hints anyone?  How-To?  FAQ?


TIA,


Geoffrey L. Wright

When Zen borders on Kamikaze.....

DTML Document --> product method --> DTML method

I've been banging my head against this for 4 days in a row now. I want 
to call a DTML method, via a product method, from a DTML document, but
I don't succeed in setting the client namespace for the DTML method to 
the original DTML Document's namespace.

I'd appreciate any help!

I have a DTML document. It has a valid aq_parent. From this DTML document, 
I'm calling a product method, passing the DTML documents's aq_parent as
an argument:

<dtml-var "NFGnavCore.aqqy(aq_parent)">

This method has access to the aq_parent object all right, tested
OK. Next, the DTML method is called from the product python method and
the original aq_parent object is given as the new acquisition context:

	def aqqy(self, context=None):
		""" some test method"""
		retval= "Hi! I'm the aqqy method, called with context.id <b>%s</b>" % context.id
		return retval + self.aqqy_helper(client=context)

The DTML method 'aqqy_helper' is called all right, but has no access
to the context object passed in. Any attempt to access objects that
should be in the acquired namespace, for example:

		 My aq_parent id= <dtml-var "aq_parent.id">

results in an error message:

          You are not authorized to access aq_parent. 

Which, if I'm not mistaken, is caused by the validate routine called 
from OFS/DTMLMethod.py as documented in 'oldvalidate()':

        if inst is parent:
            raise 'Unauthorized', (
                'You are not authorized to access <em>%s</em>.' % name)

So what am I doing wrong, and what is the right way to call DTML
methods from product methods?

Well, this gives you the ability to create, for example, 'Car' and
'Bicycle' objects, and designate them both as meta type 'vehicle', then
create an 'Owner' relationship between 'vehicle's and 'Person's. A
trivial example, to be sure.

I suppose the relationship objects could be 'instrumented' to allow
other types of filtering criteria. Whatever the criteria though, the
possible objects need to be presented through a 'relationships' form
within the ZClass instance.

You're right, one-to-one relationships should be implemented as well,
but as you noted, this proposal is not as critical to implementing
one-to-one relationships as it is for many-to-many.

That's pretty close. My proposal actually has two levels of indirection:
first the relationship objects that are relevant to the ZClass are
obtained from a ZCatalog like object (the relationship folder in the
control panel), and then those relationship objects (themselves
ZCatalog-like) are queried to obtain the objects that the ZClass
instance is associated with. Then you should be able to access these
objects' properties and contents as if they were contained within the
current object's relationship:

<dtml-in Author>
<dtml-var name>
</dtml-in>

By doing it this way, you can add relationship types between you classes
as your application grows in complexity without having to re-instantiate
all your objects. All you would have to change would be the add/edit
methods in the ZClass, and whatever viewing methods that you want to
expose the new information (other than the relationships tab in the
management intrface).

Neither approach would give me the ability to refer to linked to objects
as if they were sub-objects. This is critical for the simplicity of the
DTML to access the associated objects' contents and properties. In
short, I want a pseudo sub-object that acts as a proxy for the real
object, not a symlink I can follow or resolve to access. The end result
is much the same, but the semantics are radically simpler with my
proposal. Note: associated objects should NOT appear within the
'Contents' tab.

First, relationship_aware is optional; all it's absence means is that
the object is not aware of it's outgoing relationships. Other
relationship_aware objects could refer to it with no problem. Second,
if, for example,  you want a relationship_aware Folder, just subclass
Folder and relationship_aware in a new ZCLass.

Zope doesn't know how to call or execute php code.  To do this, you need
to have Zope make an 'external' http call back out to Apache, which will
execute the php code, return it to Zope, which returns it to your
client.

Here is a good how-to on it:

Hmm. This update has broken all my zsqlmethods I've tested so far.  I've
reverting to 2.1.4.

Eg when testing from the management interface:

File D:\zope2\lib\python\Shared\DC\ZRDB\DA.py, line 459, in __call__
    (Object: sqlShowComment)
TypeError: too many arguments; expected 4, got 5

SQLSESSION has also died with this version release.

I couldn't find 2.1.4 on zope.org, but had a copy of 2.1.3, and that has
fixed all my zsqlmethods now.  Win32.

Hi everyone,

I'm using Amos's RSSChannel prodcut along with XMLDocument, but it seems
that upgrading to 2.1.5 has broken it. Can anyone else verify this?

Can you describe how it is broken?  Is there a traceback?  Are both
RSSChannel and XMLDocument broken?

Notice that line where it refers to RSSChannel.py. It's pointing to the
RSSChannel.py file in my previous (2.1.4) version of Zope. Odd.

However, it might have something to do with the fact that when I installed
2.1.5 I didn't untar a fresh copy of RSSChannel, but copied it to the new
directory instead. I did that because I'd made some changes to
RSSChannel.py and another file and didn't want to redo them. I did a 'cp
-a' if memory serves.

I was under the impression that you could copy the directories in
lib/python/Products/ over to a new Zope. Obviously it didn't work in this
case.

I think integer division was covered last week on this
mailing list.  Change 1/24 to 1.0/24 (the upshot is 1/24 is
evaluating to 0).

Fabrice,

I ran into similar errors.  Here's the response from Jo Meder that helped me
get MySQLDA compiled:

I suppose line 1125 of mySQLmodule.c is something like:

	tf = & (mysql_fetch_field_direct(self->res,j));

If this is the case, try applying the following patch to your
MySQLmodule.c (this is strictly "works for me"):

Subject: [Zope] Looking up object instances in a folder
Message-ID: <38D4C514.ED1D3EB5@funcom.com>

I have some instances of my own ZClass in a folder, and I can iterate
over them using:

<dtml-in "somefolder.subfolder.objectValues()">
  <dtml-var title>
</dtml>

The instances are stored using auto generated ids (simple numbers).

In addition to being able to iterate over the instances in the folder, I
also need to access an instance directly by using its id which is passed
in the REQUEST object, but so far I have been unsuccessful. What I am
trying to do is something like:

<dtml-in "somefolder.subfolder.getInstance(REQUEST.id)">
  <dtml-var title>
</dtml-in>

but I have not been able to get access to just the one instance (but
iterating works fine as mentioned before). Could somebody with a clue
give me a hint?

Thanks in advance,

   The ZMySQLDA is used (and will be used) by so many people that this
information should be packed into a HOW-TO and published along with the
very DA.

Subject: [Zope] Find object in a directory question
Message-ID: <20000319141420.A2559@mimar.demon.nl>

Hi,

I've created a ZClass 'CLink', which contains a URL, title and such things.
In my dtml-pages, I can do <dtml-var slashdot>, and the slashdot-clink
object will insert the <a href=...></a> stuff for me. I've got this 
working using the Renderable class. 

I've planned to put all CLink objects in the /links folder so I can
automatically create 'bookmarks' out of the links I reference to. I also
want to be able to categorize the links into subfolders, so I want to have
a links.sports.ski.resorts directory with ski resorts, and a
links.news.nerdish folder for nerd-related news. 
I can use <dtml-var links.news.nerdish.slashdot> to refer to the slashdot
object that way. 

However, I want to easily change my categories, without changing all
<dtml-var ...> that reference object in the categories. So I figured, I'd
make it <dtml-var links.find('slashdot')>. This should one day be the same as
<dtml-var links.news.slashdot> and the next day the same as
<dtml-var links.news.nerdish.slashdot>. With my external method (which only
looks in the current folder so far), I can't get this to work. 

Any ideas? Would the same be easier or simpler using a ZCatalog? 
Refering to a link should not be too much typing. 

As an extra question: is it possible to refer to an object in multiple
places, like softlinks (or hardlinks) in unix? Suppose I have a folder with
'My Frequent internet-visits', and 'News', they could both contain the same
CLink. Is that possible in zope?

Well, hope I made anysense..
Thanks,
    Chris Niekel

test linux installations later.
   I have problems upgrading to 2.1.5 - initially Zope came up well, but
when I tried to install 3rd-party modules (including SiteAccess) - I could
not login. I didn't traced the problem to SiteAccess or other product yet...

Hi,

Any recommendations for a good Python book? I found 'Learning Python 
- Help for Programmers', 'Python Essential Reference', 'Programming 
Python' to name a few.

Any suggestions?

Thanks!

Jonathan

Hello!

   Five minutes experiment - and the problem is narrowed down to
SiteAccess. Clean and fresh install of Zope 2.1.5, than some 3rd-party
modules - Zope came up well. install SiteAccess - and I cannot login to
Zope. Authentication failed all the time. Seems SiteAccess became
incompatible with latest Zope. Go back to 2.1.3, waiting for new Zopes
and/or new SiteAccess' :)

Hi,

may be some people might remeber my question concerning the user folder
question. Well, I haven't got any answer yet. But I found a source a knowledge
that would give me all the information. Basically I don't need much more then
the register DTML method of zope.org. Is the DTML source for the user
registration and user updates available for download somewhere? When I hit the
view "DTML Source" link I get a "Not Found" error. Everything else on Zope.org
can be inspected this way, but why not these pages? This can't be such a
security problem at all. Or am I just to dumb to discover the trick.

Thanks for any hint.

Best regards,

   These pages probably written in Python, hence there is no view_source
for them.

Subject: [Zope] Property Sheet access from Python Products
Message-ID: <200003191153560734.0E5EF386@iqtinc.com>

I am creating a product in Python and I want to use property sheets. I am able to add sheets and add properties to those sheets. However how I have to access the property sheets differently than if I was accessing property sheets on a ZClass programmatically. I suspect that I am perhaps not using the right mixin classes.

For instance, I have a property sheet 'Private' with an attribute 'prop1'
If I create this in a ZClass, I can use 
<dtml-var prop1> to access my attribute.
in my class I have to do the following
<dtml-var "propertysheets.get('Private').getProperty('prop1')"><p>

likewise in Python code I must access the attribute using 
self.propertysheets.get('Private').getProperty('prop1')
where in a ZClass I could do 
propertysheets.Private.prop1

My class declaration is as follows mixins:
class base(ObjectManager,PropertyManager, 
    Acquisition.Implicit,
    Persistence.Persistent,
    RoleManager):

Am I missing a mixin somewhere? Or do I have to access the attributes differently from a Python Class?

Thanks 
Bob

Could you give us some more detail?

First of all, and this was probably just a typo on your part, but the two
products will appear in the "Available Objects selection list", not in an
"External Methods" list.

If they don't appear there (after restarting Zope), go to the Control Panel
and click on Product Management at the bottom of the page. If the installs
of Squishdot and TinyTables are busted you'll see them listed as such on
this Product Management page. Click on each broken item and send what it
presents you with to this list. Someone will be able to help with it at that
point. What I've just described is the procedure for debugging a failed
Squishdot install per it's installation instructions.

And you do see a folder for each of these products in your
zope/lib/python/products dir, right?

Hello all,

I think I have Zope running. I can get to the localhost:8080/manage page
and go into the Control Panel and External Methods.  I've tried to
install TinyTable and Squishdot by untarring them in /var/zope with
subdirectories preserved. No go -- they don't seem to show up in
External Methods as they say they should by the Squishdot Install guide.
Can anyone help?

Ahh, thank you. The Squishdot documentation is quite non-specific and says
you'll find it in Available Options.  The first Available Options I found was
under External. I see them now and have created a Squishdot site selecting the
demo.  Not sure how to get to the first page of the demo which I've put at
localhost.  Can you tell I'm new? -- IV

Python Essential Reference before it went to print and it is also an

I saw the same problem under 2.1.2.  What was even odder, I deleted my
equivalent of NewTestVersion, and recreated it.  After entering the
version, my browser still said 'working in TestVersion'.  Restarting
the browser fixed that, so it must have been some sort of caching

Message-ID: <003601bf91e9$0c1d5680$265eb5cf@kevin>

I've built an application with ZOPE and would like to create a Java
interface to it (probably using jpython/wxWindows)

Here's how it should work:

When changes are made on the ZOPE site by a client, a notification is sent
from ZOPE to the Java interface and displayed in real-time. The idea here is
not to have a continually refreshing Java window, but a window which updates
only when it receives a message from the site to do so.

What I don't know is how to send the data from ZOPE to the Java client.  Can
anyone point me to any existing ZOPE Products/Projects/How-To's which are
similar to what I've described, or perhaps point me in the right direction?

This is because Zope has challenged for a username/password, and KFM doesn't
handle that nicely.

Either put http://user:password@localhost:8080/manage (iirc - there is a HOWTO
about this) or use a more sophisticated browser, like Netscape (but beware the
memory leaks when editing textareas. ):

David,

In order to use the management screens, you need to use a browser that
supports HTTP basic authentication.  To my knowledge, KFM does not
support this.  Use Netscape or Mozilla.

Hmmm.  Tried that, but still no luck.  Zope give me a
NameError, and tells me method is trying to reference a
nonexistent variable (fullname).  Here's the current
draft of my code:

<table>
  <tr>
    <th>Name</th>
    <th>Description</th>
  </tr>
  <dtml-with bwlib_abilities>
    <dtml-in "fullname('AbilityClass')">
      <tr>
        <td><dtml-var fullname></td>
        <td><dtml-var description></td>
      </tr>
    </dtml-in>
  </dtml-with>
</table>

Where bwlib_abilities is the name my container class,
AbilityClass is the subclass in question, fullname is
the sorting criterea and a poperty of AbilityClass, and
description is also a property of that subclass.

I know I'm hanging on something silly here, but I can't
for the life of myself figure out what it might be.

Also (as a more general sort of question):

Is this way of organizing data (ie, a bunch 'o
subclasses in a container class) a reasonable way to
deal with lists (50 to 100 items) of quasi-dynamic
objects?  I'm from more of a more traditional database
background, and am used to putting this sort of info in
a table.  But in the case of this particular app, ZODB
seems idea since it provides several less technical
users of the app a ready-made interface to these objects
and I don't really need access to this data outside of
this single app.  But there seems like an almost
daunting amount of flexibility in the way I might
organize this data -- objects in folders, subobjects in
container objects, zcatalogs, etc.

Thanks,

That behavior is expected. As far as I remeber, KFM (in the 1.x versions) 
does not support HTTP authentication. 
Furthermore, 
http://localhost:8080/manage?__ac_user=superuser&__ac_password=PASSWORD did 
not work for me either.

I don't know how KDE 2.0' new konquerer will handle it. But as much as they 
worked on this application, it will work there. Can anyone confirm that?

Regards,
Stephan

sha is an optional python module.  Presumably it wasn't included
in Modules/Setup when you compiled your python, or wasn't included in
the binary set if you got a binary distrabution.  (It should
be a dynamically loaded module).

The module is used if you request sha encryption on the password.
If you choose some other encryption type the sha routines won't
get called.  So as a quick fix you could remove the sha from
the import line.  But you probably really want to recompile python
to make sure that all modules Zope uses are included.  Hopefully
there's a list somewhere, though I can't recally seeing one...I just
enabled all the modules I could <grin>.

Message-ID: <Pine.BSI.3.96.1000319220658.3933H-100000@twirl.bitdance.com>

There was a recent mention of using Lynx to access the management
interface of Zope.  I'd like to use w3m.  It produces a more pleasing
page given all those little spacer images Zope uses.  Also, it
automatically launches vi for me when I hit return on the edit
screen's text input area, which is *way* cool <grin>.

However, it doesn't seem to be handling the management interface
correctly.  If I descend into a management link, I get the 'view'
panel for the link instead of the manage_main screen.  Worse,
I tried to 'rename' an index_html method, and it renamed the
index_html in the *parent* folder!  This is most weird.  Anyone
know what Zope could be emitting that w3m is not handling correctly?
I'd guess redirects, but I'm surprised I end up in the view screen
in that case...

I'm currently running w3m beta-991203.  Anyone know if whatever-it-is
is fixed in a later version, assuming there is one?

This is w3m's fault, it does not send the Authentication header to
frames in a frameset, just to the frameset.  Zope calculates
'manage_workspace' based on various factors, including whether or not
you are authorized to access the managment view.  Since you are
effectivly 'anonymous' in the frame it shows you the anonymous view. 
Uncheck 'View' for anonymous and you will probably get a 401
Unauthorized.

I don't think it's Zope's fault.  In this case, w3m is probably ignoring
or not understanding the <base> tag.

You are either not using the right python, or you are using an old
python.  Python 1.5.2, including the python that comes with Zope,  comes
standard with the sha module.

It's now a standard module as of 1.5.2.  I presume matt is using an old
python or turned off sha.

i got the setup running on rh6.1, running userdb (cookie auth) for
authentication, run start as root.  i've chmod -R nobody.nobody * in Zope.  i
copied my previous Data.fs to replace the Data.fs that comes with
Zope-2.1.5-src.  will this be the cause?  i've been upgrading this way since
2.1.0
i did run with -D, but saw no error.

I knew it was all w3m's fault, since it all works in other browsers <grin>.

Thanks for letting me know what the likely problems are.  Whether or
not I'll have time to do anything with the information remains to be
seen.  I wonder, though...I'm starting from the manage_main URL,
not the manage URL, so the page I'm starting from doesn't have
a frameset as far as I can see.  Descending into a folder works,
but descending into, say, a DTML_method gets me the view.  Well,
I'll have to just ignore the whole thing for now.  w3m is a nice
browser, I hope they get these bugs worked out soon.

I do still find w3m useful, though.  Since it's U command to go
to a new URL does accept relative specifications, it's pretty
easy to use that to descend into the 'manage_main' view of
the items I'm interested in.

I can confirm this, SiteAccess broke my 2.1.5 installation.  Oleg, if
you want 2.1.4 I can email it to you.

Zopistas and MikeP,

I'm trying to use etcUserFolder, and I want it to actually authenticate
off of /etc/shadow. saying /etc/shadow as the Password File doesn't
work, presumably because Zope is running as nobody.  Is there any way I
can let just etcUserFolder run as shadow?

On a similar note, am I doing something terribly stupid/compromising
here?

You can just use File objects to store the flash content, and refer to the 
objects from HTML the same way you would from a static HTML site.

I wrote a special Python object for it, inheriting from File, just so it 
would take care of its own HTML tag, just like the Image object does. 
This because the site in question contained quite a lot of different Flash 
objects, and the widths and heights changed sometimes during the course of 
the design. The designers just had to upload their flash content into these  objects, which they very quickly got the hang of.

However, for the one Shockwave game in the site, I just had the Shickwave developer upload to a File object, and the HTML for it was handcoded into the reffering HTML page.

No, that is the best way. Note that you don't have to give that user a password, and that for users from the specified set of IP addresses the authentication will be transparent.

when I was cataloging my zope site and was editing i did get a conflict
'competing' writes, which reminded me: how many times does ZOPE try to write
to the ZODB and then 'fails' and roll's back - is it 3? assuming this size
is configurable where would I go and change this?  when i was cataloging i
got this:

'\000\000\000\000\000\000\350\217' <- this happens right before the
competing writes. could someone explain what this \xxx\yyy\zzz is?

and how do I redirect ZServer's console to a file?  I'm in DOS right now
(havent done this in awhile) - and tried to "C:\Program

that didnt work..  In linux I've tried redirectings stderr and stdout to a

I believe that is python's octal representation of an internal object
index.  The 'could not load state' means the ZODB tried to load
the object from disk storage and could not complete the operation.

I'm getting those on my own database and haven't yet had the time
to track down where they are coming from.  I fear some sort of
database corruption, but so far the system has continued to function
despite these errors.

And I can't get it to work at all.  etcUserFolder.py says to put a file
in a directory called etcUsers in the root zope folder.  OK, I made a
folder zope/etcUsers/, and copied my /etc/shadow to there.  Then I
edited it to just have a few names:passwords.  then I chowned nobody. 
This wasn't working.  I copied it to the directory of the product-
lib/python/Products/etcUserFolder.
No juice.  while from crypt import crypt worked on the command line, I
still copied cryptmodule.so to my zope directory.  No dice.  So I copied
it to etc's directory.  No juice.

etcUserFolder still tells me there are no users whatsoever. what am I
doing wrong?

Yeh, and now that ZSQLMethods don't work neither does GUF with MySQL - e.g.,
the following code fails:

  <dtml-in "sqlGetUserRoles(username=username)">
  <dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'].rolename)">
  </dtml-in>
  <dtml-return ret>

With the error message:

  "You are not authorised to access 'rolename'"

The method has a Proxy role with appropriate access to the MySQL method.  It
just doesn't seem able to access the results variable!?

   Thanks! But I have it, and I didn't remove 2.1.3 directories while

I'm getting the same error on Zope 2.1.5. My zclass A which inherits object
manager. Inside it I have zclass B. When I try to create B object inside A
folder Zope gives me an Attribute Error: _getOb inside
B.createInObjectManager ()
It seems then Zope does not see class A's parent object manager. But, I have
exported A objects containing B object from 2.1.4 to 2.1.5 and that works.

There are no problems on 2.1.4. Classes are first defined on 2.1.4 an then
exported to 2.1.5.

Zope is built from source on RH 6.0, python 1.5.2

Hi,

  I've tried to write one generic SQL method and
passing argument to my SQL method using dtml-let but I
got KeyError. I've tried it with dtml-with also but
same thing. 

In my page I use:

<dtml-let curpage=total>
  <dtml-call hitinsert>
</dtml-let>

and MySQL method is:

update zp_stat 
set <dtml-var curpage>  = <dtml-var curpage> + 1

What I want to do, is passing mySQL argument and 
using one method. Ex:

<dtml-let curpage=astro>
	<dtml-call hitinsert>
</dtml-let>

total and astro are INT in my SQL table.

I dont know if dtml-let is a right way?

Any suggestion to do this?

Thank's

You can't, unless Zope runs as root (which would be a very bad thing).
This is by design.

The best you can do is:
    1) Setup Zope to run as its own user (eg. user 'zope') instead of
       user 'nobody'
    2) Add a crontab job to copy the /etc/shadow file to where Zope
       can see it, changing ownership to user zope and removing group
       and other permissions.

If you run Zope as the nobody user, then the encrypted passwords will
need to be visible to this user, as well as any other processes that
run as user nobody which is not a good thing.

Message-ID: <4.2.0.58.20000320110253.00a07c50@192.168.0.2>

Hello,


I upgraded to Zope 2.1.5 (Win 32) Saturday and carried out changes in the 
database (eg. created new ZClasses, added ZClass instances, etc.)

I had a nasty system crash (Win 95) around midnight Saturday. When I 
reopened Zope I realised the database was back to its 16:22 status:
- All new objects had vanished.
- The last transaction logged in the Undo list is dated about 16:22.
- The very Data.fs in the filesystem is stamped 16:22 if you can believe it.

I checked the Z2.log and it shows these missing changes. So I didn't dreamt 
doing them.

I suppose these changes are lost?


Cheers.

This makes the shadow password suite worthless.
Assuming readonly access to /etc/shadow it's better to use a simple 
wrapper program that can do the access. This program should be carefully 
designed to not allow arbitrary input to compromise security.

One example is checkpassword (not for non-root programs) which is located 
at http://cr.yp.to/checkpwd.html
It's designed primarily to get a simple interface to various 
authentication schemes, but my be used as an example.

method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Hi! 

I thought I'd forward this to the list in case it helps anyone else:

If you want to use FTP with SiteAccess then you'll need to add the following to SiteRoot.py, after
line 124 (at the end of the SiteRoot class), and at a similar place in AccessRule.py:

    def get_size(self):
        '''Make FTP happy'''
        return 0

If anyone knows WHY this makes it work, please let us all know! :-)

cheers,

Chris

Read the documentation at www.zope.org. I think the best is to start with 
the feature tour and then "Zope Content Manager's Guide".

Is this really what you want to do?  Under this scheme, user 1 views the
site, clicks on the maxamize box, and gets the rerendered page.  Now
user 2 visits the site, and sees the maximized box.  He doesn't want
that one, so he minimizes the box.  Now user 1 clicks to maximize some
other box, and suddenly his previously maximized box is minimized.

Or am I missing something about your design?

In any case, changing properties in this way to store state is going to
cause your ZODB to grow quickly as each property state change is stored
as a new, undoable, transaction.

It seems to me you want to use either some sort of Session product to
retain the state, or do what I suspect the tree product does and
put the state you need to set/save into the URL using argument
passing ("?xxx=yyy") or by using forms to submit the change requests
and storing the state in 'hidden' fields in the frorm.

Your need a list of the AbilityClass instances in 'bwlib_abilities',
which you can sort by fullname. Assuming 'AbilityClass' is the meta-type
of your subclass, try something like the following: 

<dtml-with bwlib_abilities>
     <dtml-in "objectValues('AbilityClass')" sort=fullname>
       <tr>
         <td><dtml-var fullname></td>
         <td><dtml-var description></td>
      </tr>
     </dtml-in>
</dtml-with>

Subject: [Zope] mimetools -- an example, I hope this helps
Message-ID: <H0001bac0796f0b3@MHS>

I had to play around to get mime stuff to work right.  I needed to email
messages to about 1500 people.  Every person reaceived a couple of documents
that were the same, and each person received one document that was unique for
that individual.  I also through in a timer loop to provide a one minute delay
between each email message.  (Our mail server could not handle the load.)  I am
enclosing the code that worked for me.  Of course ymmv :)


pull_contacts : this is an sql method which pulls user information out of an
Access database.  Most of the variables listed come out of this database.

dtml-log : I used the logger product to create some logs so that I could see
that my mail messages went out.  I don't think this worked the way I wanted it
to work.

mime tag :  I added some custom code to the mime stuff because the mime stuff
does not add the mime version 1.0 header.  This may not cause problems for
everyone else, but it does cause problems for HP OpenMail and Lotus Notes.  I
do not know if anyone has fixed this in the standard zope code, but it was not
working when I did this mailout.

"_[QUESTION].data" :  this was what I had to do to pull in the unique object
for each individual.  (I imported all of my documents into the zodb.)

that makes sense.

ok, this i don't get.  i'd have thought that since i opened
what i thought was my own instance of a Zope DB, using my own
FileStorage pointing to a file in /tmp:

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/foo.fs' ) )
	connection = db.open()
	root = connection.root()

that this would have nothing to do with the DB that Zope
was using for its internals.  all of the code examples i've
seen for ZODB are from python programs, and all include code like this.
if this *is* using Zope's internal DB instance, then that would imply 
that you can't use ZODB outside of Zope when Zope is running.
what am i missing?

> (why you are getting the

it appears that was unrelated.  i actually got my example to
work since posting.  the "unable to access" thing only happens
when i get an exception due to bugs in my code.

cool.  that's good to know.

indeed.  that's part of why i wanted to use a completely separate
database.  the other part is so i can use the same routines outside
of Zope, perhaps at the same time.

i'll try that.  thanks for your help.

thanks, i'll give that a try.  i don't really need a counter, at all.
it was just a minimal example to try and figure out ZODB.

That's very odd. I tried reproducing this and couldn't.

What do you mean by parent?  Presumably, A subclasses ObjectManager.
Right?

That's because export/import doesn't use createInObjectManager.
 
I suggest one of the following:

  - Try a very simple example that you can deacribe completely
    so you can explain it to me in complete detail and I can try to reporiduce
    it.

  - If your database isn't too big (or if you can reproduce this
    with a small database) send me the database. I'll look at it and see if I
    can see what's going on.

I'm not seeing this. What are you trying to add the ZClass to?
Zope 2.1.5 has a fix to ZClasses that makes it work correctly
with ObjectManagers, including ObjectManagers that don't use 
instance attributes to hold sub-objects.  All ObjectManagers should
implement a method, _getOb, that is used to get an object from the object
manager. If you are adding your instance to an object that is *not*
an object manager, then the above error would be expected.

Problem actually solved (by digging arount in how-tos). Some remarks:

Yes, I save the state of the boxes with their properties. Where else
should an object save its state? I mean, "state" IS a property of  the object.
In terms of object orientation, this seems to me to be a much more logical
design than to save session stuff in some non-zope external database or file.

O.k., my ZODB might grow, but is it really that much of a problem (I mean,
a problem that can not be solved by just packing the DB once in a while)? Any
experience with that out there?

The problem with concurrent users switching each other's boxes from one state
to the other only occurs if they use the same objects. What I use in my
implementation is seperate box objects in different user folders. Those objects
only contain stuff that is customized. All "heavy lifting" is done by methods
in the aqcuisition path, so that there is no real duplication of code even
though the complete box structure is duplicated. In a later stage, those objects
(currently just empty folders with a view properties ...) will become instances
of a class.

The cool thing about this is that the portal becomes extremely customizable.
You can add boxes only you can see, use different rendering methods,
style sheets, whatever can be put into a folderish object.

My idea is actually working quite well now. I'll try to make it a ZClass and
put it on the web. But first I want to do some testing.

As soon as I find the time for it, I'll put my ideas into a how-to.

Please disregard this. I didn't perform the test correctly.
I now can reproduce this. Stay tuned.

Message-ID: <38D64B95.99E1F5FA@sistelnet.es>

Hello everyone:

I have posted the second part (Use Cases) of the zope memepool project at
http://zope.sistelnet.es/memez

The final goal of this project is to have a completely functional
memepool-like application, product or whatever, built completely from
scratch, using Zope. The project tries to use a completle Object Oriented
approach to development, and (since I am no Zope guru) feeds from user
comments and recommendations.

Please have a look.

Sorry this update took so long, but this past month has been busy as heck.

Best regards.

Yes, what I didn't know about your design was that the objects in
question were specific to the user.  In that case, and if it is not
expected that the user will want to change his settings with every
session but instead this is a customization feature, then what you
have described sounds like an ideal application of Zope and its
object machinery.

I think it all depends on how frequent the updates are and how many
users you have.  If your site gets to be high enough traffic
and users make frequent enough changes for it to be a problem, you
could always switch to an undo-less backing store for the ZODB and
therefore not have to change your implementation to continue to
scale. Others with direct experience with portal-like sites may have
more useful input.

Are you, by the way, aware of the Portal Toolkit project?  I haven't
investigated it yet, but if you aren't following it it sounds like
something you'd be interested in.  I'm sure they are thinking about
scalability issues there.

I want to compare them has dates and not strings with the built-in cmp()

OK, so it's not my favourite editor but I thought I'd

Can anyone tell me what I should set EDITOR_CMD to?

'C:\WINNT\system32\notepad.exe' and 'C:\WINNT\system32\notepad.exe %s'
don't do the job. (What's the %s for anyway?)

The %s will be replaced by the filename. This so Notpad knows what file to 
edit.

You will have to double the bacvslahes for this to work, because in Python 
(as in many programming languages), the backslash has special meaning:

  'C:\\WINNT\\system32\\notepad.exe %s'
 
or, you could place an 'r' in front of the string (r stands for raw):

  r'C:\WINNT\system32\notepad.exe %s'

ZopeEDIT will open Notepad for you. When done, you save and close notepad. ZopeEDIT will ask you wether or not you want to save the file to Zope. Click 'Yes', and your changes are now on your Zope server.

Subject: [Zope] dtml-let and MySQL
In-Reply-To: <20000320100802.14614.qmail@web4001.mail.yahoo.com>
Message-ID: <4.2.0.58.20000320162316.00ca5100@195.60.12.162>

As I understand it any variables you set in <dtml-let> </dtml_let> blocks 
are local to that block of code. There's no way to 'pass' them to an SQL 
Method. SQL Methods only use values which have been set within the REQUEST 
variable. The REQUEST variable is where Form variables are held - but Form 
variables only exist until the next Form is called. You can however 
explicitly force values into REQUEST using the syntax

<dtml-call expr="REQUEST.set('yourvariable','yourvalue')">

and these would then be available to an SQL Method.

A tip which I found very useful when working with the REQUEST variable and 
forms is to put the following line into your code
<dtml-var REQUEST>.

This displays all the current values within the REQUEST variable.

There's also a useful How-To on Namespaces which gives more background on 
this area (search for Namespace in www.zope.org).

However IMHO its an area of Zope that needs a lot more documentation and 
tutorials because I don't think it's very intuitive.

I also think it would be nice to have a version of SQL method which allowed 
you to pass the values you want into it - it's beyond me at the moment though.

Good luck

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985DC@pces.cadlab.it>

[Absolute beginner's question...]

I'm thinking to use Zope for an Internet site I have to develop for an
internal client. They will just receive a PC Box from me and will know
nothing about the technology in it.

I wonder if I can safely allow them to drop HTML documents inside Zope. This
would allow to publish their own simple HTML documents without worring about
DTML and the like (I do not think they are interested in developing their
own DTML-enabled sites...).

Is it Zope able to handle plain HTML+CSS+JavaScript documents, without
having to use any DTML file?

Can the user just drop a HTML document in a server directory and have this
document published on the intranet? How can I determine the directory they
can use?

Thanks.

        1. play with the imap settings (probably need to change the
           LS* variable in IMAPHACK.py, can't recall it's exact name)
        2. make sure you are running 1.0.4 (a fairly recent version).

Sure.  Although with a little work you can have it automatically get your
intranet's headers and footers, for example.  But just plunking it in works
just fine.

Give them a user that only has permission to access a certain folder.  Then
set up ftp for them and they'll never know it's Zope.

Not exactly, but close enough.  A DTML Document could certainly
contain just HTML code and no DTML, and Zope would happily return
it and the client would render it just as if (say) Apache had
returned it.  I presume you could use the ftp server built in to
Zserver to upload the documents to whatever folders you had given
them permission on.  But keep in mind that all the Zope data is
stored in the ZODB (a single file in the unix filesystem) not as
seperate files in that filesystem, so any update transactions need
to go through Zserver somehow or another in order to update the content.

You might want to consider teaching them the (pretty easy) management
interface, though, as they could use that to upload files directly
from their PC desktops using just their web browser.  Who knows,
they might even decide they want to start taking advantage of Zope's
content management features, and actually start learning DTML <grin>.

Zopists,

Are there any other quoting methods besides html_quote and url_quote?  I
am looking for something that turns periods and minus signs to an
alternative as well.  I guess I could roll my own external method, but
I'd rather not if there are more to choose from.

Doh**2. That now works very nicely. Thanks. One last request:

Any way of suppressing the reflection of the password in the

Message-ID: <Pine.OSF.4.02.10003201131530.4100-100000@batman.tamucc.edu>

Currently, I have a customized standard html header, and would like to be
able to use the same header for all files, but have different titles for
each...I have tried using this in my header:

<title><dtml-let var="'TITLE'"></dtml-let></title>

and then using this in the individual file:

<dtml-let var="'TITLE'" 
value="'My title'"">
</dtml-let>

I only use the "'....'"...becuase otherwise, I get syntax
errors.....however, when I look at the source code on the page, it reads
<title></title>...so apparently this is not working.  Any suggestions?

Thanks,

This is the second report of this bug but I cannot reproduce this, can

You can't.  As security policy, we do not write code that lets Zope open
files outside of the Zope directory.  You can, of course, do this in
your own code, but we do not recommend it.  My first version of
etcUserFolder actually was able to open files anywhere (hence the name)
but I was enlightened by Jim that this is a possible secuirty hazzard.

There error occours because there are pickles in your database that
cannot be loaded.  The 'persistent' information for an object in the
database is a 'pickle', or a serialized representation of the object. 
In order for the object be loaded into memory the pickle needs to be
unwound into an object in memory.

However, this serialized representation does *not* contain any active
code, it's just the state of the object.  In order for the object to
truely 'come to life' the pickle must be matched up with the python code
that all objects have in one way or another.

This error occours when the pickle can be read, but no coresponding
python code could be matched up with the object to bring it to life, or,
an error occoured while object was being unpickled.  Unfortunatly, there
aren't any better iagnostic tools to find why these pickles cannot be
unloaded, and for the most part they are now orphaned objects, you
cannot delete them or manage them or remove them from your database.

I can envision some kind of tool like fsck or scandisk that goes through
your database (probably offline) and lets you examine/purge/fix these
kinds of dead objects.  Ty Sarna has come up with an introspectio ntool
called the Tranalyser that would probably be a good place to start.

from DateTime import DateTime

Now you can instantiate DateTime objects like so:

DateTime(string)

and compare them easily:

if date1 < date2:
  print 'foo'

Hi,

I just wanted to let you know that this has been fixed in the zope 2.1.4-3
package; never, never, never release a package without having it installed
yourself once, I know ;-)

Thanks for the report,

Message-ID: <Pine.LNX.4.10.10003201247220.564-100000@lawlearn.wuacc.edu>

I'm trying to create several screens to allow my technician to keep a log
of problem reports.

I chose to create a search form.  The data will display in the usual table
form and the user will select the item wanted for display in an update
form with the values shown as default field values.

In the table view, I created a link to my next form in the following way:

<a
href="http://localhost:8080/School/Admin/Computer/displayitem?id=<dtml-var
id>&Submit=Submit&Query">

The problem is that no data gets stuffed into the values="" attributes of
the form which leads me to believe that either I'm not using the
<dtml-sqlvar> tags correctly or I'm not calling the data selected from the
database (mysql) for use in the new form correctly.

I read the how-to on inserting sql data, but I want to create a form that
will update existing records.

Any help will be appreciated,
Joe

Thanks.  One problem that arises when I do this, is that in my
webpage, when I do  "view source" I have ...


stuff
<title></title>           ---> From the standard_html_header file
stuff

<title>mytitle</title>    ---> From the file itself

I guess I am wanting to know how to tell the header to place the correct
title in its own <title></title> portion, and not to add a second
<title></title> line.

Thanks,
Jessica

Subject: [Zope] ExtensionClass
Message-ID: <FRQFOV$I2ZLh74u5vUUBGyDxD3ExLIi5oGV5zoaH@uol.com.ar>

Hi!

I have an ExtensionClass(es) question and, being the 
latest releases of them distributed with Zope, I 
decided to ask it here.

Situation:

1) Class A subclasses 2+ extension classes E = 
{E1,...,En} and perhaps another non extension classes C 
= {C1,...,Cm}. That is, class A(B1,...,Bk): ...., where 
B1,...,Bk are each in E or in C.
2) a is an instance of A (a = A())
3) a.foo(bar) is invoked
4) getattr is invoked in the first extension class in 
the inherited classes list (i.e. the first Bi belonging 
to E)

Question:

What happens then?
I guess that calling Py_FindMethod (inside getattr 
implementation) will trigger a search in instance and 
base classes' dictionaries, but what about the other 
extension base classes and what about the searching 
order?
I can't find any doc on these, so I'm needing your help.

Thank you, Carlos.

(Snip.)

This is due to a fix in Acquisition to a bug that obscured a bug
in the handling of inner ZClasses. Sigh.

We'll be putting ot a release to fix this. In the mean time, if you wish
you can edit lib/python/App/Factory.py and change the line:

    _setObject=Acquisition.Acquired

to:

    _setObject=_getOb=Acquisition.Acquired

You are exactly right!  I took out the title lines in the file, and just
kept the title line in the header, and gave my file a title...and voila!
Thanks!

Yes.

Actually, there is a buglet in XMLDocument that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

In 2.1.5, when you add an XML document, you get a
WrongDocumentException.  This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py.

There may be other problems, however, I'm not very familiar 
with XMLDocument and wouldn't be a good person to find them.

Perhaps you could apply this patch and see if you can find 
anything else wrong.  If you do, please provide me and Amos 
with some sample data and instructions for reproducing the problem.

It did work.  The filename that appears in the traceback is the name
of the .py file when it was compiled to produce a .pyc file.
Since you copied the pyc file, the old name was retained.

Please see my other note for information on a fix to this problem.

It looks like you are trying to use an anchor tag to submit a form. 
This will not work as it is not proper HTML.  You need to use an <input
type=submit...> or some other valid way of submiting the form.

Hi,

sofar I solved the creation process of user accounts. This was quite easy
after I read the code for this. But now I have problems adding new roles via a
specialized interface. I setup tghe REQUEST object correctly, then I call
manage_defined_roles and I get various errors. Is their any method at all to
create Roles besides the management interface of Zope or via External Methods?
Setting local roles is easy, but I can get the role added to the system at
all. Any help appreciated. Thanks a lot.

After reading the how-to that Kevin Dangoor and making some changes from
the management interface, I am able to edit values connected to my Zope
objects. While this is a start, it really isn't ideal. As Nick Henderson
suggested, it would be better if there was a way to do this from standard
DTHML, so that the editing form looks like a filled-in entry form? Does
anyone have any suggestions? Also, a number of the fields in my entries
are coming from "select" lists or checkboxes. This is being done to
control the vocabulary so everyone enters the same term for the same item
(eg. It would be a problem for my application if person #1 calls it "Time"
and person #2 calls it "Time Magazine." Does anyone know of a way to take
the existing values of an entry and pull it into a select list and tell
the list to keep them "selected," or have an idea of a direction to go
in order to attempt this?

There's actually three parts to every error, the error type and
description, and the traceback.  Could you also send the error
description (it's above the traceback) so that I can look at the code
and they to see  what is raising the TypeError (which is the error
type).

What kind of errors?

You should be able to call a method that adds roles just like the
managment interface does.  Have you checked out
lib/python/AccessControl/access.dtml?  At the bottom is a second form
that lets you add roles.

Michel,

I'm trying to use a link on the Report Form to call another form that
displays the single database record with each field filling in the new 
form.  If the user is the proper authenticated user, an update button will
be available, anonymous will only get a listing of the record.

Granted, I'm not doing it the right way. Perhaps my question is how do you
select a value, in this case the record number, and use that value as a
key to pass the entire record to the form for display.  My calling DTML
Method is listed below.

So the question is how can I call up my new form with my selection
appearing as data.

Thanks,
Joe

Message-ID: <4.2.0.58.20000320194209.01654a20@192.168.0.2>

Hello,


I got a similar error with Zope 2.1.5 on Win32 Saturday. Here's how:

- I created a ZClass, TestClassA (it subclassed ObjectManager).
- In TestClassA, I created another ZClass, TestClassB (it also subclassed 
ObjectManager).

So I got ControlPanel / Products / AProduct / TestClassA / TestClassB.

Then :
- I created a TestClassA instance somewhere.
- In this instance, I tried to create a TestClassB instance.

I got:
Error Type: AttributeError
Error Value: _getOb

Somehow this was related to RESPONSE. This error didn't occur when for 
testing I added ", RESPONSE" to the line

   <dtml-with "TestClassB.createInObjectManager(REQUEST['id'], REQUEST)">

in the "TestClassB_add" constructor method.


Cheers.

Alexandre

I'd really like to see a global method that replicates the property sheet
editor but is callable from code rather than the management interface
and can thus be "wrapped"...

There is some sample code somewhere that shows how to mostly do
this in DTML.  I looked at it, but wound up just creating my own
specific editing form anyway, because I couldn't get it to run
out of the box and didn't have time (or at that point the knowledge)
to debug it.

Here's a snippet of code from my custom edit form that does this for
a multiple select property I have.  Hopefully this will help you roll
your own.  'regions' is a lines property defined on another propertysheet
(named 'constants' <wry grin>).  I haven't yet figured out how
to call this variable so I can use it in the addForm.)  I basically
copied this out of that sample code I mentioned above.

  <tr>
    <th><label id=in_regions>In Regions</label></th>
    <td>
      <select name="in_regions:list" multiple size="7">
        <dtml-in regions>
          <option <dtml-if
            "_['sequence-item'] in in_regions">SELECTED</dtml-if
          >> <dtml-var sequence-item></option>
        </dtml-in>
      </select>
    </td>
  </tr>

Actually, i need to access to sequences at the same time. That's not

The '%s' gets replaced by a temporary file name, it definitly needs to
be there. I know nothing about notepad.exe, but it sounds like notepad
can't accept filename arguments on the command line. I can't verify this
however. I know people are using ZopeEDIT in Win?? so it must be
something with notepad.

Hi Oliver - would you expand a little bit on how you "solved the creation
process of user accounts?"

Thank you.

Brian,

It appears to be a good fix.  I'll run with it and let you know how it goes.  I suppose that I should  cc the list as well.

Hi Curtis -

We are going to be releasing a fixed update today - in 
the meantime, if you could try something out to verify 
that it fixes your problem as well, that would be great.

I've attached a file ZRDB.tgz. If you copy that to your
lib/python/Shared/DC/ZRDB directory and unpack it, then 
restart Zope you should be working again. If you have a 
minute to try this can you let me know how it goes? 

Thanks!

Suppose that Bi belongs to E (following the previous 
names) and is not, for example, Persistent, and that Bj 
is Persistent (where j > i).
The problem of the getattr (I mean in Persistent) 
invoked only when the attribute being accessed doesn't 
belong to the instance dictionary or class dictionary 
is still here, isn't it?

Subject: [Zope] my zope has got no pid!
Message-ID: <000a01bf92a4$f172fd00$1cf108c3@SteffenLemke>

Hello there,

something's strange with my zope. I am running zope as my personal zope-user (at least I have started it this way) but I don't get any pid if I say "ps -a". And I cannot stop the server because the script tells me kill: xxxx - no such pid? What's wrong with it?? Is there any additional flag I have to set or unset in the standard-scripts? 

Thank you for your help,
Steffen

Ok this problem is due to the bug in 2.1.5 that also breaks ZSQL
Methods, it is unlrelated to ODBC.  We will be releasing a 2.1.6 that
fixes the problems in 2.1.5 including this one.

try 'ps aux' (on linux at least).  Any other platform, who knows.

I don't know.

No, but certainly your Zope is running with a PID, it must be.  Go to
the control panel, you should absolutly get the right pid there.

Here is what I did to get it going...

EDITOR_CMD = ' "notepad" %s' 

# I put a space in there just to make it easy to see for the email but by
quoting notepad the command line gets interpreted properly.

Message-ID: <613145F79272D211914B0020AFF6401914DE8B@gandalf.digicool.com>

Hi all,

Zope 2.1.6 has been released - you can download it from
Zope.org:

http://www.zope.org/Products/Zope/2.1.6/


This release fixes a few issues with Friday's 2.1.5 security
update release:

  o Some bits from the currently development branch got into
    the 2.1.x release branch, causing problems for folks using 
    certain database adapters - this has been fixed.

  o A fix to Acquisition that happened in 2.1.5 caused a problem
    with ZClasses, since some of the code in Factory.py previously
    worked around the problem and now no longer needed to. This has
    been fixed in 2.1.6.

Users of the SiteAccess product should note that the security 
changes in 2.1.5 necessarily require a change to the SiteAccess
product - as he noted in a previous email to the zope list, Evan 
will be releasing an updated SiteAccess shortly.

Also, the XMLDocument product has a buglet that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

Currently, when you add an XML document, you will get a
WrongDocumentException. This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py. A new 
rev of XMLDocument containing this fix will be available soon.

Note that we have also posted "diff" updates as .tgz files 
that will let you easily upgrade an existing 2.1.x site. 
These updates are available for those currently using the 
2.1.x source release or the 2.1.x binary releases for either 
solaris or linux.

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

In an NT cmd.exe shell:

  ...2>C:\temp\zope.err >C:\temp\zope.log

or:

  ...2>&1 >C:\temp\zope.log

should both work.  On Win95/98, I think you're sunk -- the COMMAND.COM shell is
too brain-dead.  You might try 4DOS or another replacement shell.

"Broken pipe" says that the peer process/thread on the other end of a pipe died
without shutting down the pipe cleanly.  You should be concerned, because these
are your "Zope" threads that are dying -- eventually, you will have none left to
service requests.

This problem is a symptom of something inside Zope which is killing off threads,
most likely an unhandled exception somewhere.  Try turning on the
STUPID_DEBUGGER_LOG and see if you get more enlightening log output.

Hi,

well I use the following code snippet in my factory method of the product I am
developing.

<dtml-with "manage_clone(Home, REQUEST['new_id'], REQUEST)">
        <dtml-call "manage_changeProperties(
                        company_name=REQUEST['new_company_name'],
                        title='OS Job Tracking System für ' + REQUEST['new_company_name']
                    )">
        <dtml-call "acl_users.manage_users(submit='Add Role', REQUEST=REQUEST)">
        <dtml-call "manage_defined_roles(submit='Add Role', REQUEST=REQUEST)">
    </dtml-with>

I set the role element of my REQUEST object to a string, which is the name of
the new role. When I look a manage_defined_roles in
lib/python/AccessControl/Roles.py it searches for a submit element in the
REQUEST object that has a certain value. Otherwise it calls manage_access. 

Well, I set submit to the required value, so that _addRole is called. Then I
get the error

    Error Type: AttributeError
    Error Value: aq_acquire

And when I call it without setting the parameters at all

    Error Type: KeyError
    Error Value: SCRIPT_NAME

When I call it with REQUEST=REQUEST I get the first error again.

Any idea what is wrong with my call? I am not using any external method or so
from product, but I develop the product in Zope and use only DTML scripting,
cause this is sufficient for my task.

I am running Zope 2.1.4 as a standalon zserver. May be this helps too.

Any hint would be really fine.

Best regards,

    Oliver Andrich

Hi,

I just discovered something strange. At least I think that it is strange. I
can assign users Roles that don't exist at all in the system. In my last Email
I tried to create a Role in a system wide context. Well, know I removed the
role add code and just added the user with a fantasy role. Now the management
screen can't handle the user anymore cause the role doesn't exist. But when I
do a acl_users.getUser('admin').getRoles() I get the fantasy role I
    specified. Ok, this is not the solution, but should the manage_user code
    check if the role that is specified exists at all?

Bye, Oliver

start.bat is all you need.  It will leave a dos-box open, but that's fine.  It
will show you some (occasionally) useful output from Zope.

Once you have run it, take your handy web browser (NutScrape, or Internet

Steffen

This happens when you rename the Zope directory after installation.

The stop script has a hardcoded directory in it.

If you edit the stop script and change the old directory name to the new one
all works as expected.

Vladimir,

I just had this same thing happen, and bypassing the factory worked.
I changed the calling method from calling "maClass_factory to
myClass_addForm, and the add method worked fine.  That seems very buggy
to me.

The traceback was posted onthe zope-dev list this morning.

Here it is anyway:

<dtml-with "WorkDayClass.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-call "propertysheets.WorkDay_properties.manage_changeProperties(
             work_date=REQUEST['date'],

 <dtml-call reindex_object>
<dtml-with>

Now I get:

Error Type: AttributeError
            Error Value: _getOb

Subject: [Zope] Sybase: How generate id keys? (surrogate keys)
Message-ID: <20000320232355.87383.qmail@hotmail.com>

Hi,

How do people generate id keys (surrogate primary keys)
in Sybase+Zope? There are some recommended ways of doing it
in Sybase with stored procedures but I can't run stored
procedures in Sybase.

I am looking at heavy-traffic strategies. So I need something
slightly better than a simple increment table for the keys.

Any recommendations? Thanks in advance.

D'oh!  The environment variable which Zope checks for is STUPID_LOG_FILE:

 * If it is set to a blank string, Zope writes the verbose logging
   to stderr;

 * If it is a non-blank string, Zope opens it as a file and writes the
   verbose logging there;

 * Otherwise, Zope suppresses the verbose logging.

Ayup, there have been several threads reporting such restarts lately -- have you
been following them? (some were on the zope-dev list, I think).

Just to add my two cents:  I've seen these as well, usually connected to
someone disconnecting from downloading a page mid-way, usually also
connected to zope going into a really tight 'select (0,1), select (0,1,2),
select (0,1,2,3), select(0,1,2,3,4), etc loop - until it runs out of fd's
it's allowed to open, crashes, and needs restarting.  Oh, and only when
running with FastCGI.

My response so far has been to whack a while : ; do ... done loop around
the kickoff command in ./start, and run the whole lot under screen -dmS.
STUPID_LOG_FILE didn't produce anything that was immediately useful to me
:(

I've just upgraded to 2.1.6, and so far I haven't seen the problem, which
may or may not be a good sign ;)

Hello all,

I have the following code fragment in a method called
CategoryCustomizationForm contained in the folder /News:

<dtml-if preferences_saved>
  <hr>
  <b> Your preferences have been saved </b>
  <hr>
  <dtml-call "manage_changeProperties(preferences_saved=0)">
</dtml-if>

where "preferences_saved" is a property of the folder /News.

In the folder /News, the security view verfies that the permission of
"Manage properties" is allowed only by those in the "Manager" role. In
order to allow all authenticated users to use
the "manage_changeProperties" method in "CategoryCustomizationForm", I
assigned the proxy role of "Manager" to "CategoryCustomizationForm".
However, zope still only allows users in the role of Manager to access
"manage_changeProperties" in my form. In other words, the proxy role
assigned to the method "CategoryCustomizationForm" failed to override
the permissions of its containing folder /News. As a temporary fix, I
gave the "Authenticated" role permission to "Manage properties" in
/News. This works with regards to allowing all authenticated users to
access "manage_changeProperties" in my form. However, in the long run, I
don't want all authenticated users having manager type access to all
properties of /News. I have this failure of proxy roles in other areas
of development too, such as dtml creation of folders via manage_clone.
Is there something I'm missing about how to use proxy roles? Thanks for
your time.

Unfortunately the IDENTITY column is not a good option.

According to our local Sybase expert, The IDENTITY columns
are just too buggy to use, even after the newer releases of
Sybase. They cause too many troubles, that is why we are
looking at alternatives. In older versions of Sybase, the
problems were so severe that they would cause the database
server to crash. Some drawbacks that were mentioned:
(some are fixed, but these are not the only problems...)

(1) When database server crashes, apparently the IDENTITY
    column jumps to the next block of values, so the table
    index space become sparsely populated, and you may hit
    the roll-over situation earlier than expected.

(2) When using BCP utility to download and upload tables,
    there are some problems with the IDENTITY columns, too.

(3) It is hard to access the values of the IDENTITY column
    when you are in multiple SQL statements.

Anyway, there seem to be too many problems, so the IDENTITY
column approach has been discarded. :(

regards,

Hung Jung

I've released LocalFS v0.1.7. It hasn't been tested extensively so I've left the
bits for v0.1.6 up on the site. I'm just too excited to wait. :)

The url is: http://www.zope.org/Members/jfarr/Products/LocalFS

Enhancements in v0.1.7:

- Added the ability to customize mappings between file extension, content-type,
and Zope object class.
- Added the ability to customize content-type to icon mappings.
- LocalFS objects now work with the <dtml-tree> tag, so they can be traversed
using the navigation menu.

(plus a few bug fixes)

If you try it out please let me know what you think or if you find any problems.

Thanks,
-jfarr

Subject: [Zope] ZClasses and clone/delete methods
Message-ID: <14550.61379.392791.186258@antares.int.plain.co.nz>

I need to know whether I can set up clone and delete methods in a
Zclass that automatically get invoked any time someone deletes or
copies an instance of that class from the management interface (via
cut and paste or whatever). 

What I'm doing is creating a simple link class that just stores the
key to a RDBMS row that contains all the details of the link
(description, URL, clickthrus etc). The trouble is that when a link is 
deleted from Zope, it needs to touch the db record or that record will 
become orphaned - ideally the db record needs to keep a reference
count of the number of link objects out their, and they need to
increment or decrement that count as they get copied and deleted.

So can this be done with a ZClass (if not, why not :-)) and if it
can't, how can I do this with a Python Product (given that I've never
written one!).

TIA,
John.

Message-ID: <38D6F845.A010DBE2@suprize.com>

Hi,

    I have Zope 2.1.5 and Oracle 8.0.5 running on the same Linux box.
ZOracleDA was installed successfully and bridged Zope and Oracle.
I can call my stored procedure by creating Z SQL Method like:

    begin
    procName(arg1, arg2,...);
    end;

But I cannot get return arguments (OUT args) no matter how the Z SQL
Method is set. I have tried the interfaces mentioned in DCOracle
documents, but failed. The only work-around I've found is creating 
extenal methods and import DCOracle via python. Is there any way
to get the OUT arguments from Z SQL Method? Thanks a lot!

I've read
http://www.zope.org/Members/Zen/howto/FormVariableTypes
and a few other HOW-TO's and still haven't figured out
how to make use of the :record type in form variables.

My form looks like:
<form method="post" action="processForm">
<input type=text name=choice.1:record>
<input type=text name=choice.3:record>
<input type=text name=choice.10:record>
<input type=submit>
</form>

Now processForm need to tell which and how many choice.x:record are entered.
This works:
	<dtml-var "REQUEST['choice']">
that's as far as I can go. I want to do:
	<dtml-in "REQUEST['choice'].keys()">
		<dtml-var sequence-item>:<dtml-var sequence-value>
	</dtml>
but it doesn't know what "keys()" is.

Question: how do I get the keys and values for this "choice" record in
processForm?

Thanx,

iI'm going to have to disappoint you.

- I never published the object, it was simple and not that general. Also, I cannot release it now, because it was written while working for my previous employer.

- The site for which I used it was for a big Dutch youth event, and now that it has taken place the site has been taken down again.

Record objects do not implement a mapping interface.  Form elements are
turned into attributes of your 'choice' object, so your objects has
instance attributes named 1, 3, and 10.  You will need to use
_.getattr() to access these attributes since numbers are not very good
attribute names.

It might be a good idea to look into a new ZPublisher type called
:dictionary (or :mapping) that works much like :record, it would be
fairly trivial to implement, want to take a stab at it?

Subject: [Zope] ZODB Couldn't load state - help please
Message-ID: <38D73050.8A2546B8@knoll-is.de>

Hello Zopers,

I just joined these mailing lists. I have a boring problem I can't
understand. I wrote this little program:

import Persistence
import ZODB
import ZODB.Transaction
import ZODB.FileStorage

class dbclass(Persistence.Persistent):
	def __init__(self):
		self.thedata = 'testdata'

def getdata( request=None ):
	name = 'somename'
	db = ZODB.DB(ZODB.FileStorage.FileStorage('myfile.fs'))
	connection = db.open()
	root = connection.root()
	if not root.has_key( name ):
		print "initialising"
		root[name] = dbclass()
		get_transaction().commit()
	r = root[name].thedata
	connection.close()
	return r


This program works very well if it is started directly using the python
interpreter. But if I call it from Zope using 'Try it' in the management
console it works only one time. The second call of the function results
in:

Zope Error

          Zope has encountered an error while publishing this resource. 

          Error Type: AttributeError

Subject: [Zope] discussion/forum product/zclass
Message-ID: <00032116404602.04048@tokey.kedai.com.my>

hi all,
i've been looking at confera and zdiscussion as a possible forum solution. 
however, i'm also looking at other perl/php products.

my Q:
-anybody on the list have deployed confera/zdiscussion on  a large site?
-what will a lot of traffic do to Data.fs?  will i have to pack often?
-i'm looking at modifying zdiscussion to store to an RDBMS.  anybody done that
already?  if so, mind sharing how you did it?
-i'm not a python programmer.  and i would like to implement filtering for
certain words/malicious html tags.  i see an external method here.  any other
solution?  dtml maybe? :)

i thank all for your help, pointers, docs.

I had the same experience a few days ago with a 2.1.4 installation running
under Win98. I have a couple of different Zope instances running on Linux and
Windows, but that was the first data loss. It seemed to me as if the session
had been running in "demo" mode so that changes would not be really persistent.
As in Alexandre's case, I first thought I was dreaming because there was no
hint of my data except for the log files.

I suggest some further investigation into that. If Zope really lost things that
easily, I'd consider not using ZODB for production sites ...

BTW: In my case it also was a Windows system crash that caused the data loss.

This sounds like Win98 is using a write-cache that didn't get flushed to disk
because of the crah. IIRC, Zope forces write cache flushes, but it could well
be that Win98, being a client-patform, ignores that for performance reasons.

Then again, who'd use Win98 for production sites?

Try %1, instead.  %1, %2 etc stand for a commands first, second 
... positional parameter in the MSDOS/Windows/Windows NT

*Sigh* Did anyone read my reply to the original message?? A backslash has
special meaning in python! And positional parameters have nothing to do with
python either!

In python (as in many programming languages based on C) \n means newline. Just
fire up a python interpreter:

  >> repr('C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\012otepad.exe %s'

\012 is the octal representation for newline. Note that, as \W and \s are
meaningless, they are interpreted as if you used a double backslash.

The solution immediatly becomes clear:

  >> repr('C:\\WINNT\\system32\\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'
  >> repr(r'C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'

ZopeEDIT uses the string to build up a command to feed to the system. It uses
the default python % operator to replace the %s (which is a C-sprintf-like
string formatting code) with the filename of the temporary file it creates.

Please, next time, use the python debugger or something to see what goes
wrong. Paul has long since gotten ZopeEDIT to work, BTW.

Subject: [Zope] Weird ZSQL Method thing...
Message-ID: <38D760E4.F25D1D00@nipltd.com>

Hi,

This is weird, I've got a solution but I don't know why I need to use it...

I have a DTML Document that uses two ZSQL Methods, something like:
<dtml-in item>
  ...the item ZSQL method returns cid...
 <dtml-var cid>
 <dtml-in case>
    ...the case ZSQL method takes cid as a required parameter
 </dtml-in>
</dtml-in>

Now, using this returns an error: Bad Request: [cid] 
which I've grown accustomed to seeing when a requried parameter is missing.
However, if I dtml-comment out the second dtml-in, it works fine and the correct cid is displayed by
the dtml-var.

The only way I can get it to work is to make the second dtml-in look like:
 <dtml-in case(cid=cid)>

I really don't understand why I need to do this and why the 'case' ZSQL method doesn't just pick up
cid from the current namespace...

Any ideas?

Chris

Um, more or less (apart from the quotes). The ZSQL Methods use namespace
different from than normal DTML documents/methods (though I don't
exactly know how). Therefore you have to call them explicitly with an
argument.

It would work too. The dtml-in variables are not available to sub-methods,

If this is true, it's really counterintuitive and should be changed if at all possible.

If it's specific to ZSQL methods or in otherwise confusing situations, then there's even more reason
to change it...

Anyone got any comments/suggestions?

Subject: [Zope] FSSession and external methods...
Message-ID: <v04220807b4fd1bb332c0@[128.240.198.13]>

Hi all,
Anyone got any experience with FSSession and external methods 
(actually a PythonMethod).

I want to get the data out of an FSSession object using this construct-type

<argument>self</argument>

FS = self.FSSession
out = ""
for k,v in FS.items():
     out = out + "K:%s, V:%s<br>" % (k,v)
return out

and get this;

<!--
  Error type:  AttributeError
  Error value: _v_data
  -->

Looking at FSSession.py, _v_data is there as part of the FSSession class;
     def items(self): return self._v_data.items()
but it's not getting through to the method.

Anyone got a fixe for this? I need to do some heavy processing with 
the contents of the FSSession object so I can't *really* use DTML.

TIA
tone.

have you given roles to the user???
to protect the folder, I suppose you have created a role 'ROLE', and said
that anyone but those with the role 'ROLE' are able to view the folder.
however, if the users in the NT User Folder are not given roles, there are
two case:

when you create a NT user folder, you have to choose whether default
behavior when a user is not given roles is to acquire user settings from
higher user folders or not.

- if default behavior is to acquire settings, due to the very nature of user
folders, NT User Folders says the user *does not* exists if no roles are
defined, to allow higher user folders to handle the user. this is the
default for a nt user folder created in a sub folder

- if default behavior is not to acquire settings, NT User Folder always says
'yes' when the user is asked, but if no roles are defined, the user is
assumed to have to anonymous role. this is the default for a nt user folder
created at the top level

if roles are created for a user, it always exists, what ever the default
behavior is.

back to your problem: if you choose not to acquire user roles, all users for
which you didn't give roles are *anonymous*, so they have no rights on your
protected folder.

good

nope but be careful about the above point

This is not true.

Method A:

<dtml-with "_(bob='uncle')">
  <dtml-var B>
</dtml-with>

Method B:

<dtml-var bob>

_will_ print 'uncle'.

It is specific to ZSQL Methods, they create their own fresh namespace. 
There may be a good reason, I can't think of one.

ZSQL Methods create their own namespace (I don't know why).  You must
explicitly pass them arguments.  You can, of course, pass then entire
namespace:

<dtml-in "case(ns=_)">
  ...
</dtml-in>


and in your SQL Method:

<dtml-with ns>
 ...
</dtml-with>

This is, like all of my advice, completely untested and off the top of
my head, but it should fly.

We have deployed a heavily modified Squishdot site that handles around
30-40K requests a day.

Depends. Trafic by itself does not increase the size of Data.fs.

Now but we will have to. After 3000-4000 postings Squishdot is very slow
and I suppose zdiscussions too.

An external method will be appropriate. Forget DTL for such task.

IMHO, this isn't true. I have several ZSQL methods which have named parameters. 
It appears that they can get these parameters from REQUEST and possibly (I can't remember and
haven't got time to check :( ) things like dtml-let and dtml-with without having to explicitly pass
them which is why I was so surprised that dtml-in didn't work as expected.

Can anyone who knows say why this is the case and exactly what the critera are for something being
'visible' to a ZSQL method's parameter list?

HSCH,

Chris

You need to call FSSession before you can use it, as in DTML otherwise the
data will not be loaded into _v_data. I have just tried the following and
it works:


FS=self.FSSession
FS()
out=""
for k,v in FS.items():
   out = out + "K:%s, V:%s<br>" % (k,v)
return out

Martijn, you're right. Nobody would use Win98 on production systems. But quite a
few people use it on their notebooks or home PCs for development, I guess. At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Well, I don't think that is the optimum solution, especially for big sites. 
Even though that is the Zope way of doing things, I hate the idea that I 
clutter my ZODB with files. I would suggest you add a property called 
attachments to your Class which points to various URLs and then serve the 
files via Apache. You may want to use PCGI to do this.
We just switched to PCGI and now we serve Images and Documents from another 
port via Apache (we can also use SSL now). That helps to keep the I/O 
stream to the ZODB file moderate. Remember, ZODB is just big one file (even 
though Zope does a lot of caching). You could also check into LocalFS, 
which is nice in some cases (even though we were unsuccessful to upload 
files, using it.)

Stephan

Subject: [Zope] Modifying Standard Error Pages
Message-ID: <Pine.LNX.3.96.1000321140832.11696D-100000@marvin.nipltd.com>

I'm currently trying to modify Zope's standard error pages in order to
have errors (such as 404 not founds or DTML errors) e-mailed to the 
webmaster as they occur.

At first, I thought this would be as simple as modifying the
standard_error_message document found in the root of the Zope
installation, but it appears that changes to the file do not get displayed
(even after forced refreshes) and thus it doesn't seem to be in use.

A search on zope.org lead me to find the real error message embedded in
<zopedir>/lib/python/OFS/Application.py - I've modified this and it
appears to work, but doesn't support HTTP related errors such as 404s.

After a bit of a search, I've tracked down HTTP-related error reports to
<zopedir>/lib/python/ZPublisher/HTTPResponse.py but, while this can be
modified, it doesn't support DTML as the HTML error message is returned
without apparently being parsed by Zope. As a result, I can't have
dtml-sendmail send an error message report.

Okay, I could modify HTTPResponse.py to send a mail using something like
Python's smtplib, but before I do that, have I overlooked the obvious and
is there really a much cleaner, easier way to modify the error pages
without delving into the sources?

Thanks in advance!

Neither. Add orphan=0 to the tag, and you'll feel sane again.

if ommitted, orphan is set to 3. This means that if the last batch is smaller
than 3 items, that batch is added to the one but last batch. See it as a
'minimal batch size' parameter.

When you call a method 'by name' (<dtml-var methodName>) then the DTML
machinery will magically try and line up any arguments to that method
with any names in the namespace.  It will do this for any kind of method
that accepts arguments, DTML Methods, SQL Method, ext methods,
PythonMethods, and methods written in python of the object this()
etc...  _However_ if that method is a SQL Method then as soon as you
enter the method any reference to <dtml-var name> in the SQL method will
NOT find the name in the previous DTML namespace.  If you want a name in
the DTML namespace to match an argument, that's a different matter all
together, and it will work, if you want to <dtml-var name> in a SQL
Method and 'name' is in the namespace of a calling DTML method, then it
won't work.

Have a look at:

  http://www.zope.org/standard_error_message/view_source

and you'll see how the Zope.org site handles 404 Not Found.

In the current CVS they do.  Tanming, if you're using a source code
distribution of Zope you can change the definition of class 'record' in
ZPublisher/HTTPRequest.py to the following:

class record:
    def __getattr__(self, key, default=None):
        if key in ('get', 'keys', 'items', 'values', 'copy', 'has_key'):
            return getattr(self.__dict__, key)
        raise AttributeError, key

    def __getitem__(self, key):
        return self.__dict__[key]

    def __str__(self):
        L1 = self.__dict__.items()
        L1.sort()
        return join(map(lambda item: "%s: %s" %item, L1), ", ")

    __repr__ = __str__

Cheers,

Evan @ digicool & 4-am

Are these batches of records the 'last' batch in the ZSQL query?
If so, it's the 'orphan' parameter kicking in, which *I believe* is set to 3.

If you have 19 records returned with a batch of 4, you get
1-4, 5-8,9-12,13-16,17-19 - no problem there

If you have 9 records returned with a batch of 4, you *would get*
1-4, 5-8, 9 (on it's own).

The 'orphan' parameter would make the last batch return 5-9 (ie 5 records).

It's described in greater detail in the ZSQL users guide...

As many of you have noted the FastCGI site has been down since last week.
Sorry about the hassle, there were significant hardware problems.

The site is now in the process of being moved.  Until the domain
transfer is complete you can reach the new site here: http://209.212.66.147.

The mailing lists, fastcgi-announce and fastcgi-developers, have been moved
as well along with the existing list membership.

Posting to the list won't work until the domain transfer is complete:
mailto:fastcgi-developers@fastcgi.com.

The domain transfer should be complete in the next couple of days.  I'll
send another email when its complete.

Please let me know if you have any questions or problems.

Neither.  The in tag by default does not like orphans (result batches
smaller than 'size').  Set 'orphan=0' and sleep in peace that your
sanity is intact (and that the in tag is bug free).

Here's something that worked for me, it's got extraneous imports and 
stuff ('cos it's the front end of something bigger), but it does 
work. I add nnn_ to the beginning of file names so I can have more 
than one file called 'test.doc' in the directory, and I've not 
finished the URL stuff yet, but it certainly uploads normal files to 
LocalFS (probably because it bypasses the LocalFS machinery all 
together ? :) .

add_details is a ZSQL method that adds info about the upload into a database.

Martijn,

I think the problem is that any changes made to standard_error_message don't appear to have any
effect. I've tried just simply changing the text, add ' - wibble' after 'Zope Error' and the old
error message is still displayed, even after restarting Zope...

What's going on?

Is there some method such like with SiteAccess that you have to 'set' a DTML method as the standard
error message or is something else causing the old error message to be displayed?

HYCH,

Chris

I have no idea. I don't use SiteAccess, so I don't know what influence it has
on this issue. I can change standard_error_message just fine here. Try and
understand what the default code does first, then try and make a few
educated-guess changes to that code.

Does anything show up in the undo log? After a change, does the edit window
have a message 'Content changed [Date]' just below the tabs?

You've seen this before?  Great you're the first person who actually
gives me hope I'm not insane.  We have been running 7 sites from a
single zope install replicated across 3 servers.  Two of the servers
experience frequent Zope restarts (as often as every hour).  The third
server running an older version of Redhat (6.0 I believe) and
glibc-2.0.7-29, and hardly ever restarts.  

We are running Redhat 6.1, glibc from rpm glibc-2.1.1.6, python from rpm
python-1.5.2-7 and Apache/1.3.9 mod_fastcgi/2.2.3 and Apache/1.3.11
mod_fastcgi/2.2.3.

We have even gone as far as to modify FCGIServer.py to produce "debug"
output  to determine which requests go unanswered at the point of
restart; hoping this would lead to some suspect DTML or ExternalMethod
code.  No luck.

We're waiting a bit to upgrade to see how it shakes out w/ SiteAccess
etc.

We've also recently bumped cache *WAY* up, 450,000 items, w/ 5 minute
target max between accesses.  Which has resulted in 200M of memory for
the process.  This appears to have lowered the number of restarts, but
not eliminated them.

In your experience with this problem have you noticed /manage and or
traffic volume to have any impact on the frequency of restarts?  We've
been looking everywhere to determine what may be going wrong, and have
experienced the most restarts when traffic and /manage volumes are up. 
We unfortunatly have our most /manage volume within the same timespan as
our heaviest traffic.

Hopefully we can find a solution to this.  Thanks for the feedback.  Let
me know if you make any headway.

Hello,

I still can't figure out why my DTML document gives me the following
Zope error :

    Zope Error

    Zope has encountered an error while publishing this resource. 

    Error Type: AttributeError
    Error Value: __call__


when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?


Thanks in advance,
Greeting,
Eric

This is what happens when an exception is raised while rendering
standard_error_message (obtained through acquisition).

ZPublisher renders the default standard_error_message, rather than let
a problem go unreported.

Hi,

As I found out - you can not index numbers and therefore not search 
for dates using the zCatalog.

But I was wondering 'bout workarounds. I thougt maybe if I could 
change the bobo_modification_date to one of my own. That I could 
search for. But that seems like a pretty crappy workaround...

Ideas.... anyone ???

Has anyone modified the Zope index method to also index numbers ??

I think that's probably wrong. The thread-safety-ness of MySQLdb is that
two threads can share the module. You can't safely share connections, but
this is more of a MySQL limitation than a MySQLdb limitation. Of course,
you can share connections if you wrap a mutex around it so that only one
thread uses it at a time, but it is far better to have multiple
connections: Each connection is a seperate MySQL thread on the server
side.

The old MySQLmodule was probably thread-safe, but not thread-friendly: If
you ran a blocking operation (like a query), it would block all the
threads (i.e. it did not give up the Python interpreter lock during
blocking calls). This apparently causes really bad performance with Zope.

I may be deficient on Zope zen, but it seems like you would definitely
want to have several connection objects around, perhaps one for each ZSQL
Method, so that these can all work in parallel. From a security
perspective (i.e. you aren't just paranoid, you know they are out to get
you), this may make sense, as you can set up seperate users in MySQL with
very specific privileges, so each connection object can only do one thing
and can't be hijacked for something else.

Yup, just discovered this myself. :-) I put a buggy dtml expression in the
document and Zope displays a default message rather than the custom one
I've generated - removing the buggy stuff brings the custom version.

Thanks to Martin for pointing me to the 404 handling on zope.org, I've
solved the initial problem I was having with getting changes recognised in
the standard_error_message in Zope's root, and now have it mailing a basic
error report to the webmaster.

There are a few issues Chris noticed when he was doing some stuff, but I'm
going to take a look at these further before posting more on the subject.


Cheers,

John

Have you looked at the Zope.org error message and played with that? You should
be able to do a RESPONSE.redirect I think.

Martijn,

Yeah I look and even copied the code and fixed it to work on my server but
doing a redirect doesn't seem to work.  At best I get a blank page with no
redirect taking place.

Oh well, I'll keep on experimenting.

See ya

You may want to look at Pavlos Christoforous' FSSession or Anthony
Baxter's SQLSession products to make this happen.  Look on zope.org.

Not a problem. Use ZSQL Sessions and an update SQL statement have it fed in
from a Zope form. Do a little error checking and Bob's Your Uncle.

I don't think this is true. Catalog does not index numbers in TextIndexes,
but I think a FieldIndex would work fine. I'm pretty sure I've done it (with
dates, even), but not 100% sure.

Just make sure you use a FieldIndex, and I think you'll be fine.

Hi,

    Take a look at the FSSession and SQLSession products. They allow you to
store data on the server for each user, and I think it would be pretty easy
to implement a shopping cart that way.

Hi,

  I went thru mailing list but I did not find a
response to my problem.

I've written simple form with one text field and one
file type:

<form action="/content/result" method="post"   
ENCTYPE="multipart/form-data">
<input name="c_title" width=30 value=""> 
<input type="file" name="c_body:file" width=30>
<input type="SUBMIT" name="SUBMIT" value="Submit">
</form>


result method is:
....
<dtml-call "manage_upload(REQUEST['c_body'].read())">
<dtml-var REQUEST>
....

When I press Submit button I get

Error Type: NameError
Error Value: manage_upload

Any suggestion?

b) How can I simply affiche (if I find a PB) the
upload content in browser?

c) How can insert uploaded content in MySql. I Have to
use:

VALUES
(
'<dtml-var c_title>',
'<dtml-call
"manage_upload(REQUEST['c_body'].read())">'
)

It works? it seems bizarre?

Thank's

The REQUEST object is defined in ../lib/python/ZPublisher/BaseRequest.py. I
don't see a delete there, but by studying that code, I'm sure you could
easily implement one.

Subject: [Zope] newbie CGI question
Message-ID: <Pine.OSF.4.02.10003211327080.9449-100000@batman.tamucc.edu>

I currently have a site that uses numerous perl cgi scripts....I have
successfully managed to transfer all the static pages to Zope...however,
what about CGI scripts?  Does Zope support them?  Can I use the Zserver
with these scripts or should I use the other server (with Apache)?

Also, from the Zope experts out there, I need your opinion.  I am
considering using Zope for my existing web site (it's fairly large)
...however, I would still like to continue to use perl/cgi, (have a
lot of time invested in my already existing scripts), and not use much
Python (no flames please...haha).  I like the graphical capabilities of
Zope, and the ability to assign roles to  certain users...but I don't know
if this is worth switching, especially if I am going to continue to use
perl/cgi (if that's even possible)...any suggestions out there?

Thanks in Advance,
Jessica

It seems to me that all this would require is passing the "_" namespace in place
of the REQUEST when calling the ZSQLMethod -- am I missing something?  Values
found in the REQUEST would still be found, but would be overridden by any
intermediate namespaces (e.g., from dtml-in, dtml-with, or dtml-let).

[RH] REQUEST is a python dictionary, but probably one that DC has altered
for security (or other sound reasons). I once used REQUEST.clear(), which
flushes the whole REQUEST  (this was necessary because I wanted to do a
batch operation on a fileobject of 500K , but didn't want to pass it around
several times). This worked, I believe (but I never tested this through).

Martijn, you're right. Nobody would use Win98 on production systems. But
quite a
few people use it on their notebooks or home PCs for development, I guess.
At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS
in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and
restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Joachim.

[RH]Hm, I have been developing for quite some time on an feeblish win95
machine at home, which repeatedly crashed, but I have never ever lost
committed transactions. Strange.

Message-ID: <003501bf9376$b97ec460$0100a8c0@pinol1.sfba.home.com>

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in
general?

    Zope has encountered an error while publishing this resource.

    Error Type: AttributeError

when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?

[RH]Can you send us more detailed information:
the exact dtml for the local and the subobject method and the traceback of
the error (you can get it by viewing the source of the error page)

The REQUEST object stores form data in its .form member, which is a Python
dictionary.  You will need to find a way to execute the statement, "del
REQUEST.form[ 'variableToErase' ]", or the equivalent expression, "delattr(
REQUEST.form, 'variableToErase' )", neither of which can be done from DTML or
from PythonMethods (ergo, must be done in an ExternalMethod or done from a
Python product).

Subject: [Zope] Installation Directory Problems in a W2K install
Message-ID: <PKEBIHPBEGMAPMNHFPCFGEGNCKAA.jlv@volition.org>

Hi.

I installed Zope 2.1.6 on a W2K machine and have one problem installing
additional components.

I have tried to install TinyTable, Squishdot, Photo, ZPhoto-Album, and
others but NONE of them get noticed by Zope when re-starting the service.

A clue, I believe, is in this error message when trying to "import"
ZPhotoAlbum.zexp:

---
Zope Error
Zope has encountered an error while publishing this resource.

Error Type: Bad Request
Error Value: File does not exist:
C:\PROGRA~1\ZOPE-S~1\import\ZPhotoAlbum.zexp
---

Shouldn't that directory be:

C:\PROGRA~1\ZOPE-S~1\inst\import\ZPhotoAlbum.zexp

???

None of the lib installations that would be in ..\inst\lib get noticed upon
restart, which leads me to think that somewhere in the installation it
doesn't have the "installation" setting correct.

Thanks.

Jason

I always thought the inst directory was used by Zopeat install time and only
then.

Any products should go into <zopedir>/lib/python/Products

Any zexp files hould be in <zopedir>/import

You shouldn't need to put anything in the inst directory.

I'm pretty convinced it's related to glibc version - the fact that a strace
of the process shows it repeatedly opening/selecting over more and more
fd's just before the process goes away suggests some sort of funky error
handling to me - maybe one of the socket handling routines had a change in
what error it produces between glibc versions?  Anyway, I haven't had time
to sit down and properly dig.

2.1.6 suffers the same problem.

I can reproduce it instantly with a large enough page - stop the request
mid-way, the closing of the socket to the client while Zope is serving the
page up seems to be what causes it to go into it's loop, then die.

Mondo apologies to the zope crew for not putting this in the collector - I
had hoped to find the actual problem (and maybe a solution) first, but ran
out of time :(

Sometimes you do, sometimes you don't. I know that sometimes I can acquire ZSQL
method parameters from the request. Sometimes I have to provide them explicitly.
I haven't been able to figure out what the rules are, either. If anyone out

Ok,  I finally did it.  I got my boss to slip a nice little application
server in the budget.  So here I am trying to spec out a nice Zope server.  
 
What should my priorities be when building this beast,  I think we'll be
able to spend about $10 Grand on this beast.  We will be running a secure
site using Apache and OpenSSL,  and we are targeting about 100 continuous
concurrent users.  I have already set SOME priorities, because uptime is a
big issue so the server will have redundant power supplies and hardware RAID
5.  
 
Beyond that,  what do you suggest.  Is memory more important than processor
speed?  Is it important to go with a Multi-processor server or will Zope/
Linux take advantage of a multi processor setup?  
 
 
Dream a little server for me :)

You will have to use Apache + mod_perl + mod_rewrite + Zope.
This way, you send the CGI requests to the cgi-bin, and the
rest requests to Zope. The details could be somewhat involved. :(

(see the following quote in
http://www.apache.org/docs/mod/mod_rewrite.html

`` Despite the tons of examples and docs, mod_rewrite is
voodoo. Damned cool voodoo, but still voodoo. ''
-- Brian Moore
bem@news.cmc.net
)

But it is definitely worth it. And I would guess many people
out there actually use this configuration.

I guess it is possible for someone to write some Zope product
for Perl (a la mod_perl), but it would be major engineering to
be fully compatible with Perl. If you don't mind re-launching
the Perl interpreter every single time (I know, it's primitive),
it's easy to execute the perl command from a Zope external method.

For now, the best bet is probably Apache + mod_perl + mod_rewrite +
Zope.

Hung Jung Lu ,
Along these same lines, I have a C++ CGI App that I would like to call from
zope.  It requires a couple of parameters.  The app can either return HTML
or I can have it save the output to a text file.  Ultimately, the text will
need to be displayed to the user from Zope.
Q1.  How does one call a C++ CGI program from Zope?
Q2.  How do you supply the C++ CGI program with "command line" parameters
from Zope when making the call?

Thanks,

Eric.

The intent of ZOPE is to replace writing CGI scripts. Zope itself often
runs as a large persistent CGI script. It has several advantages over
traditional CGI scripts detail on zope.org.

The general answer is that you'll need to put the CGI scripts in a
non-ZOPE location to use them.

I suggest deprecating your CGI scripts in favor of ZOPE classes.

Oh boy... 10 Grand?

IBM Netfinity 5500 M20

- Dual 700 MHz
- 5 x 9.1 GB RAID 5
- 2 GB RAM
- Dual NIC Cards
- RH 6.1 

Should be about 10 Grand. That thing is ROCK SOLID. It could eat 100
Concurrent users without a napkin. Can handle up to 4 GB RAM, 120+ GB of
Drive and 4 Processors. Almost everything is hot swappable (power, fan, PCI)
only time you would have to bring it down would be to so you could take it
home.

The other way to go would be to get 2 x Netfinity 5000 (Dual 700 MHz, 1 GB
RAM, 3 x 9.1 GB RAID 5). Load balance them and you are golden.

Enjoy...

Subject: [Zope] Zope hosting
Message-ID: <20000322010840.A1674@rosa.sferacarta.com>

Hallo! I'm thinking about using zope to develop some sites.

May you please advise me about a Zope hoster?
I've looked at those listed on zope.org, but some of them offer
just 20MB or have most of the site written in german.
One of them I can't even reach, others don't mention zope on
their pages, or are a bit on the pricey side.

I need a flexible, expandable solution. I may need 40MB and two
domains for a start, and more in the future. I have to install
my products and use pgsql or mysql.

Shell access is welcome, too..

Do you have some suggestion?
Which ISPs do you think are best?

 - OR -

Do you think I'd better install zope as a normal user, on one of
those cheap ISPs that give me 500MB ?


Thank you very very much.

Message-ID: <38D80AF9.3FE3909F@netspace.com.mx>

Hello,
I recently started to work with php (+ Apache), and now I found Zope. At
the first sight, Zope seems to be faster than php, but I don't know if
it's my php application that is not so complex than Zopes objects. So I
would like to ask, is there a benchmarks or articles or any sources that
discuss about performance and developing PHP versus Zope? Also, i am
cuirious, was Zope developed to replace PHP in the future? And what if
PHP comes up with an interface like Zope, so what would be better? Many
questions, isn't it ....

Any comments are welcome.

Thanks.
Nikolai

Field indexes can index any kind of picklable object value, including
DateTime objects.  This is how searching by date is done on the Zope
site.

Use Apache.

Keep the cgi scripts in Apache, migrate to Zope at your leisure.

Zope, more correctly Python will not take advantage
of a dual processor. 
I probably seriously consider buying a ZEO solution
from DC. 
I don't know, but a ZEO solution might solve the 
problem with 100 continuous concurrent users
writing to the ZODB?

Subject: [Zope] Alternating Cols or Colors
Message-ID: <38D813D2.BAB5E068@messagemedia.com>

Does anyone know an elegant way (or a way at all) to alternate what
color rows in a table are or to alternate which column a cell is on?

A less-than-elegant solution would be to somehow assign a variable 1,
check and see if it's on 1, show one color, set it to 2, show the second
color, etc... But I'm not sure what I'm doing wrong with dtml-let to do
that:

<dtml-let c="1"></dtml-let>
  ..

?

Yes it will, it just won't scale exactly two fold.  In almost all Python
wrapped C calls, the C code releases the interpeter lock as often as
possible, this allways happens, for example, when doing I/O or when
calling  database library routines.  Two processors will give you a
noticable benefit.  Four or more will probably not.

Further, Zope will not be the only process running, so a dual gives you
the usual benefits, like doing a compile on one thing without killing
your website.

ZODB FileStorage was not designed to be write intensive, the goal is to
provide a mid-write high-read solution, this solution satisfies 99.9% of
all web site needs.  You would be surprised how much money you have to
pay to Oracle to get, for example, their high write-write distributed
database solutions (its in the six figures).

ZEO is a distributed storage, but in the end it depends on a mechanism
that actual writes the data somewhere.  In the stock case, this is a
FileStorage.  If you want high-write intensity, consider a
BerkeleyStorage (which works fine as the backend for ZEO) or offload
alot of your high-write intensive data to a relational database.

The unique id problem come up again and again.

The automatically generated unique id will benefit web author with

sql row id
object id

and may be some others

With a view that zope will be run over the network with distributed storage
across the net, I would like to suggest we implement a unique id server
which can be a zope server serving on another port and serialize all request
and return the globally unique id.

Does this work?

I also suggest zope can be configured to automatically get the object id
from this service and have globally unique object ids.

As far as multiprocessing goes,  if I were to run a MySQL database on the
same server (serving primarily to Zope) then the multiprocessor config would
be a very big performance boost wouldn't it?

What about Memory?   Again with MySQL.  I suppose I should have mentioned it
right of.  Our main goal is to serve up pages from a database that will be
about 500MB-1GB in size.  There will be very little information which will
be cachable,  almost all of the queries are unique.

Does there have to be any meaning to the keys?

IOW, would a random, unique id work for you?

If so, you can take a look at:

http://www.zope.org/Members/Bill/Documentation/AutoGenID

For ways of doing it. You would insert the generated id into the SQL
table instead of the id field of a zope object.

If you are doing this inside a <dtml-in> tag, you can use the sequence-id-odd
and sequence-id-even vars, thus:

<dtml-in someSequence>
  <dtml-if sequence-id-odd>
    <tr bgcolor="blue">
  <dtml-else>
    <tr bgcolor="red">
  </dtml-if>
  <td> some stuff here</td>
  </tr>

Legacy.  python expressions were added after sequence-item.

Use the namespace object as a mapping:

<dtml-call "foo(var=_['sequence-item'])">

I asked much the same question whilst replying to a very similar question
recently.  the -'s in the names is from times predating Python expressions
(afaik).

to access that var, use the _ namespace:

<dtml-call "foo(var=_['sequence-item'])">

Sure, I do it all the time. The following way is the fastest I came up with:

- Create a style sheet that looks like that:

// even rows
td.listrow1 {
       color:        blue;
}

// odd rows
td.listrow0 {
       color:        white;
}

Then write a DTML method/document (for example displaying objects in a folder):

<table>

<dtml-in "objectValues()">
   <tr>
       <td class="listrow&dtml-sequence-even;">
           <dtml-var title_or_id>
       </td>
    </tr>
</dtml-in>

</table>

sequence-even returns a boolean  set true (1) when we have an even row.

This is untested code, but should work.

Stephan

First, you didn't provide a traceback.  Please allways send a traceback
with an error report otherwise we can't really help you.

Second, I can't reproduce the problem you describe.  I uploaded a file
into Zope, and randomly click a dozen or so checkboxes a dozen times,
and no error ever occur when I click 'Change'.

How, _exactly_ do you get this to happen?

 Our project has a requirement to have all artifacts under source
 control (in this case ClearCase). What is more, our defect
 tracking system is intergrated into our source control system
 such that work done on defects can be traced to versions in the
 source control system. The key requirment is tracability.  Any
 work done can be traced back to when, where, how and why and
 vice versa.

 The problem is Zope. To have meaningful tracability in zope
 means have some system whereby a representation of the zodb
 exists in source control and any changes by users are
 automatically reflected in the source control. The ability for
 the source control versions to be imported back into Zope would
 be a plus.

 Any ideas?

 When building a Product using ZClasses, I often want to create
 a "root" ZClass, which the manager will create in a normal
 folder, and which will then expose the Product's other ZClasses
 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel
    +- FooProduct
       + FooItem_add_permission
       +-FooRoot
         +- FooItem
         +- FooItem_add

       + FooRoot_add
       + FooRoot_addForm
       + FooRoot_Factory
       + FooRoot_add_permission

  Reviewed by:  Tres Seaver tseaver@palladion.com

 Hmmm, I don't seem to be doing so well on picking topics.  Here
 is what I had in mind:

  * This site is an instance of the 
    "ZGotW product":http://www.zope.org/Members/tseaver/ZGotW,
    which has a "main" factory, ZGotWRoot_factory, in its root
    folder.

  * This factory does *not* create an instance of a "folderish"
    ZClass, but rather, creates a normal Folder and populates
    it from a set of default DTML objects, along with a ZCatalog.

  * Individual issues of ZGotW are created within this folder
    as instances of the ZClass, ZGotWIssue, using the code in
    those "cloned" DTML objects.

 My rationale for adopting this approach, rather than creating
 a "folderish" ZClass, was to allow each instance of the "root"
 to be independently customized;  the "common" behavior of a
 ZGotW site is included in a set of utility methods, which can
 be tweaked to enforce different policies, or change the
 look-and-feel of a particular site.

 The downside to this choice is duplication of code:  should I
 find a bug in the original, default code, I have to then fix it
 in each instance as well as the Product.

 Comments, anyone?

Ethan,

Welcome to WorldPilot! (Note: I am not connected with the developers just a
user.)

In order to see other users names in any of the PIM areas those things must be
shared from the sharing page associated with the content type. In the Notes
section it works as follows and I assume similar for the other sections though
I haven't had time to work it through all the paces. If you have browse access
you can see public postings, if you have read access you can see public and
confidential postings. When in Notes any of the users who have shared
information that you can see will become visible. Example:
Tester1 enters 3 notes: 1 private, 1 public, 1 Confidential.
Tester2 has browseable; read access to Tester1's Notes. 
Tester3 has browseable access to Tester1's Notes. 

Both will see Tester1 as an option in the user selection under notes. Tester2
will see 2 notes and Tester3 only 1.

HTH,
Jack

Here is my take on it:

- Never have something high-volume-write to ZODB.
- Use RDBs and LocalFS or other ports to write to the File System.
- If you really need to large data in Zope format look at plugable brains, 
the idea is great.
- I noticed PCGI and Apache increases your performance, especially when you 
serve up big files.
   Setup: Apache using virtual hosts HTTP & HTTPS running Zope PCGI, for 
Images and for large files.
             My Images are served using port 81 and Documents using port 
82. That worked very well so far. We still have to test it live.
- I have two servers running: One for the DB and one for the rest: Mail, 
HTTP/HTTPS, Zope, SSH ...
- Even though not much is going on, the Web server has a constant use of 
400 MB RAM (so I would suggest 512 MB RAM)
- The DB server should be your real performance working horse. Buy a 
computer that will reflect your DB load...get a lot of memory though (1-2 GB).
- Put in both servers a dedicated NIC only for the DB info transfer.

I think that will  get you going pretty well. For the Web server Processor 
power maybe more important than for the DB server. That completely depends 
on how much you team likes SQL (meaning, how much logic is done using SQL).

Stephan

Subject: [Zope] PHP vs Zope
In-Reply-To: <38D80AF9.3FE3909F@netspace.com.mx>
Message-ID: <l03130300b4fe04b0d651@[206.221.224.184]>

In a technological sense, comparing PHP and Zope is a little bit silly,
since they are so very different.  In a practical sense, comparing them
is extremely reasonable, since there are a wide variety of web development
tasks which can be approached with either PHP or Zope.

Performance comparisons are the toughest.  PHP is no slouch -- it is used
for some very high traffic sites, including freshmeat.net and lots of
others.

Zope, on the other hand, offers some features which will cause it to
outperform stock PHP in many cases.  PHP is a scripting language for
website development.  In contrast, Zope is described as an application
server.  As such, Zope includes features like pooling of database
connections and caching of database query results.  These are not
as easy to do in technologies like PHP, and they can make a huge
difference in the performance of database-driven sites.  We
implemented www.CodeCatalog.com twice -- once in Zope, and once in
PHP.  The Zope version ended up much, much faster.  Your mileage
may vary.

I'm pretty sure it's possible to get good performance from PHP and
Zope, if your situation is appropriate and you're willing to work at
it.

I am equally sure that it's pretty easy to get lousy performance from
either PHP or Zope, if your situation is especially inappropriate, and
you're willing to live entirely off the low hanging fruit.

There are lots of other comparisons which could be made, and have been
made.  These comparisons tend to degenerate into flamewars pretty quickly,
although I see no reason for this to happen.  Objective comparisons
of two technologies like this are useful.  I happen to like both, although
Zope certainly gets an increasing share of my attention.

Zope's three-tiered architecture and web-based authoring tends to make
the tool more approachable by people who may be less technical, and
more annoying to hardcore programmers who find they have a new paradigm
to learn.  The gap between the experiences of these two groups of
people tends to narrow very quickly as people start to grasp the soul
of what Zope is all about.  People who are learning Zope tend to
periodically burst out of their office with a desperate need to
tell someone about the latest core principle of Zope which they finally
came to understand.  The more you have these "light bulb" experiences,
the cooler Zope is.

PHP isn't like that.  It's an excellent tool, but it's really just
a scripting language.  It isn't everything that Zope is, and it
doesn't try to be.

Compare PHP to Python

Compare Zope to Midgard.

BTW, the safest way to do those comparisons is *probably* to do them
somewhere other than on this mailing list.  :-)

Subject: [Zope] Zope : Load_site features request
Message-ID: <000501bf93cd$87f93c20$770da8c0@bbs>

Load_site is a greate product.

I am using it to upload a brunch of files to zope now, I found I have an
idea :

In order to make the uploaded zope more alive, I would like the load_site to
make everyfile in the original archive an folder in zope, with index.html
representing the structure of the original html file. And all the contents
goes to obj1, obj2, .... reside on the same folder. For example,

Index_html :

<dtml-var standard_header>
<body><p><dtml-var object1></p><table><tr><td><dtml-var
object2></tr></td></table>
</body>
<dtml-var standard_footer>

This would make the resulting zope site more close to the zen of Zope.

I am not very good in python but please give me some hints to made this
modification. Will you make the change?

Rgs,

Kent Sin

Message-ID: <38D87A4A.FFBE3FF4@fr.bosch.de>

Hi Zopistas

while trying to make gtk's (very useful) Boring Product (slightly
more) interesting, I came across the following (for me) strange
behaviour.

manage_ methods seem to always have "REQUEST=None" as their last
parameter. If I remove the "=None" from manage_edit then I notice no
difference, so the actual parameter is presumably being passed.
However if remove the complete formal parameter (and the reference to
REQUEST in the body of the method) 

def manage_edit(self, title): 
        """does this really need a doc string?"""
        self.title = title
#	if REQUEST is not None:
#	    return MessageDialog(
#		title = 'Edited',
#		message = "Properties for %s changed." % self.id,
#		action = './manage_main',
#		)


then everything still works ! Why is python not complaining about a
parameter mismatch ?

I promise to publish a Howto on making Boring more Interesting when
this madness is  over.

Thanks in advance

Thanks. That is the current work-around that I am using...
(Key derived from a time-stamp with millisecond precision.)
There is one observation and two problems:

(1) ZopeTime is not as good as the getdate() function
    from Sybase, if you are running multiple Zope
    webservers (for load-balancing.) That is, it's
    better to rely on one unique source of timer.

(2) There is a slight chance of two processes getting
    the same key, if they happen to occur within one
    millisecond of each other. The probability is small,
    but unfortunately I have to address even this minuscule
    probability. :(

(3) If the server's time is re-adjusted for any reason,
    it's possible that some keys are regenerated.

I agree that the millisecond-precision key is really good
for non-critical applications. But because of the nature of
our project, we need to address even the slightest chance
of error. :(

I think I will adapt the Sybase's recommended stored procedure
to Zope, by using DTML and ZSQL methods. It's kind of nasty
for something as simple as a surrogate key generation, but it
seems more secure.

thanks again,

Hung Jung

hmm, i must admit that I still can't get it to work with simple 
numbers. I have a field with the number "20002" but it doesn't matter 
wether i use text or field index it still don't work. Am I forgetting 
something ?? And yes - I reindex the cataloge before searching.


But I will look into the date thing right now!!!

Because Zope passes in those parameters that the method asks for. If you take
away the REQUEST parameter, Zope simply doesn't pass it in.

The manage_ methods use REQUEST=None to make sure you can use the methods in
situations there is no REQUEST to pass in. You can call manage_edit with a new
title, and have it still work, from a DTML Method without having to pass in
the REQUEST object, as you won't need the MessageDialog anyway.

Hi.

I am wondering if I can do a search/replace in the ZODB
for e.g. every DTML Document (just like search, but with a replace-with field)?
Is there anything planned or under development?
This would be rather useful to easily use Acquisition
with content imported from HTML files.
Someone could replace a menubar (which appears in all files the same)
just with the <dtml-var ...> call and create a DTML method
which holds this content.

CYa,

I think this is my point exactly ;-)

It all seems really inconsistent and I was wondering if anyone could say exactly what the 'rules'
were and why?

Interesting topic!

How does Zope compare with Midgard?
Which one is more flexible (that is: which one can be used in a wider set of
cases)?
Which one is easier to learn for the webmaster?
Which one is better fit to develop and maintain a complex web site (let's
say: 10,000 documents and 50,000 pictures, updated weekly)?
Which one is better for web sites that uses database and/or a "fragmented
document" architecure (XML/SGML documents that are disassembled and
re-assembled on demand)?
Which one can better integrate other technologies (web-mail interfaces and
so on)?
Which one is easier to use for a remote customer, enabled to develop and
maintain his pages on the server?
Which one is better for "workgroup" intranet servers?
Which one is safer (more anti-hacker)?
Which features does Zope have that Midgard does not have?

Thanks.

PS What does "Midgard" mean (I'm italian...)?

stephan, 

i agree on apache increasing your performance when serving static
files (for instance images), but wouldn't url rewriting and the proxy
pass module of apache be an even better solution? i just switched from
PCGI to the Rewrite/Proxypass combo because of the additional overhead
of PCGI. 

(see http://www.zope.org/Members/anser/apache_zserver/ for the kind of

Mmmhh, I have to have a look. Okay, I just read the the little tutorial. 
Does it really speed things up?
I guess SSL should not be hard using this solution. I will be thinking

Anyone else?

Subject: [Zope] Upload files in Zope and store elsewhere
Message-ID: <38D8B1FC.CCDA0827@funcom.com>

After some helpful advice, I have been successful in uploading files
(images) to Zope. Now I am trying to stuff the uploaded images in a
MySQL database, but am not able to access the image data.

If I try to stuff the image data "raw" into the database by declaring a
image:string parameter to the ZSQL Method and  <dtml-sqlvar image> in
the ZSQL code I get a string like "<ZPublisher.HTTPRequest.FileUpload
instance at 87956214>".

Another approach I have tried was <dtml-var image fmt=sql-quote>, but
this complains about the image being an instance and not a string.

Another approach has been to access the actual "raw" image data using
image.data in various combinations, but I have not gotten this to work
anywhere (contrary to what it seems other people have managed to do),
see this 

http://www.egroups.com/group/zope/26227.html?

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

I'd also love to be able to store files uploaded through a Zope form into a MySQL database so if
anyone else has done this successfully, particularly for medium size files (5-6 MB) please can you
let the list know!

cheers,

Chris

Hm, I _think_ I recall (but I can't test this right now) that the ZSQL
method will only accept values that are given explicitly in its
arguments and in that case it will also acquire them. That would make
sense from a security point of view.
Or perhaps it was a bit more complicated - I have to investigate this

some testing with apache benchmark:

the setup is an apache 1.3.12 sitting on port 1988.

/tstfolder/bmeth is a very simple dtml method ("i am bmeth in
/tstfolder" <dtml-call "REQUEST.set('testvar', 'hm...')">
&dtml-testvar;). 

i do 1000 requests at 50 concurrent users, keepalive-connection via
apache benchmark:

first the result of doing a proxypass to zserver on port 8080:

   --------------------


conclusion: with proxy pass i get around 30% more requests per second
and around 25% less connection time (and im not able to use keep-alive
as it seems).

please note that this is only a quick check and not scientific in any
way, and naturally the benefits will diminish when more complicated
pages are going to be served.

if there are any other test results please let me know...

Hello Marius,

TI am a Newbie to Zope and this is the first time I post a Answer to the
mailing list. But I had the same problem and I hope I can help you.

After a lot of test I find out the following method to upload images to
MySQL and after that retrieve it in the web pages.

Write the folliwing ZSQL method:

       Arguments: N_
                  Titulo
                  Subtitulo
                  Texto
                  Foto

      insert into Novedad
        (N_, Titulo, Subtitulo, Texto, Foto)
      values (
        <dtml-sqlvar N_ type=string>,
        <dtml-sqlvar Titulo type=string>,
        <dtml-sqlvar Subtitulo type=string>,
        <dtml-sqlvar Texto type=string>,
        <dtml-sqlvar
"_.string.replace(REQUEST['Foto'].read(),'\010','\\010')" type=string>
      )

Note that I replace the octal char 010 by the string "\\010".
If you don´t escaape this char MySQL change it for the char 008. I don't
know why.
To upload the image I have the following DTML Method:

<form action="novedades" method="post" ENCTYPE="multipart/form-data">
  <input type="hidden" name="accion" value="insertar_novedad">
  Nş producto: <select name="N_">
    <dtml-in listar_N__producto>
      <option value="<dtml-var N_>"><dtml-var N_></option>
    </dtml-in>
  </select><p>
  Título: <textarea rows="2" cols="20" name="Titulo"></textarea><p>
  Subtítulo: <textarea rows="2" cols="20" name="Subtitulo"></textarea><p>
  Texto: <textarea rows="8" cols="40" name="Texto"></textarea><p>
  Foto: <input type="file" name="Foto"><p>
  <input type="submit" name="submit">
</form>

Note the the line "Foto: <input type=....".
And to retrieve the image I have this DTML Method:

Method name: image

    <dtml-in obtener_foto>
    <dtml-call "RESPONSE.setHeader('Content-Type', 'image/gif')">
    <dtml-call "RESPONSE.setHeader('Content-Length', _.len(Foto))">
    <dtml-var "_.string.replace(Foto,'\\010','\010')">
    </dtml-in>

Note that you must put the 5 lines in the same line (without newlines).

ZSQL Method name "obtener_foto":

      Arguments: N_

      select Foto
      from Novedad
      where
      <dtml-sqltest N_ type=string>

To insert the image in an dtml method:

<img src="image?N_=AC-M56E">

Hope this can help you.

Excellent, just what I was looking for. 

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

and this to anyone who wants to answer: ;-)

   Anyone know why? This is a little disturbing...

Subject: [Zope] Q: <dtml-in sort=twofields>
Message-ID: <E12XlPG-0002fb-00@home.delysid.org>

Hi.

I am constructing a search interface for a catalog.
The objects I index have three relevant properties:
title (textual title)
id (the id, sortable)
book_title (the name of the book where the chapter is included)

I want to have atabular result like this:

Book 1     Chapter 1.1
           Chapter 2.1
Book 2     Chapter 1.1
           Chapter 4.2


To acomplish this I currently do something like:

<dtml-in Catalog sort=id>
  <tr>
   <td><dtml-if first-book_title><dtml-var book_title></dtml-if></td>
   <td><dtml-var title></td>
  </tr>
</dtml-in>

But, to have the list look nice, I'd need to specify
two fields for sorting, book_title should be the primary
field sorted by, and id should be the field all identical
book_title entries should be sorted on.

Is there a way to do this with dtml-in?

CYa,
    Mario <mlang@delysid.org>

btw. does anybody know of other benchmarking software? (i once tried
to grab httperf but the ftp site holding the source is down...)

So ProxyPass is 20 % faster. Cool. I will try that.

Subject: [Zope] Names containing colons?
Message-ID: <200003221420.IAA08813@beluga.mojam.com>

In my web page input forms I've been using field names like "radius:int" so
Zope will coerce variables to the proper type.  This works fine on the
server.  Unfortunately, if I have a JavaScript function on my web page to do
form input validation, how do I reference that object?  Is there some
alternate naming scheme that will allow Zope to do the type cast and allow
references from JavaScript?  Should I just forego the :int stuff altogether
and do the coercion explicitly?

Thx,

In your JavaScript functions, reference the variable as such:

forms[0].elements["radius:int"]

(Replace the "0" with an actual name if you've named your form . . .)

If a "folderish" ZClass had some way to expose its customizable parts, so
that you could go to an instance and say "instantiate a local copy of method

Excellent, just what I was looking for.

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

It's BLOB

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

< 1MB

and this to anyone who wants to answer: ;-)

   Anyone know why? This is a little disturbing...

From Python (either an ExternalMethod or a product)::

  import sys, os, string

  def ExecCGI( cmdLine ):
      """
      Run an external command and return its standard output as a string.
      """
      f = os.popen( cmdLine ) # note that Win32 has a non-standard popen()
      lines = f.readlines()
      status = f.close()
      if status:
         raise "CGI returned error: %d" % status[1]
      return string.join( lines )

To call it from DTML, passing the current values of 'foo' and 'bar'::

   <dtml-let cmdLine="'/path/to/my/cgi %s %s' % ( foo, bar )">
     <dtml-var "ExecCGI( cmdLine )">

Does this fix the FTP problem for Access Rules as well as Site Roots?

I could only get the patch we tried to solve the FTP problem for Site Roots...

I am happily using CodeIt.  They offer several options above "basic" Zope
hosting:

  * Install your own products (this is their "professional" option).

  * Add disk space cheaply (they quoted me $0.50/month for each added 10 Mb).

  * Add domains, mapping them to separate Zope folders, for $10/mo each.

> Shell access is welcome, too..

They don't offer shell access -- I FTP products, export files, etc., into a
"home directory" with a slightly oddball layout.

Zope wants to be a long-running process, with significant CPU and RAM
requirements;  most ISPs don't appreciate you running such a beast, so ask
first.

Subject: [Zope] Zope Weekly News
Message-ID: <Pine.BSF.4.21.0003221005110.8916-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday before Noon.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * Two new Zope revisions were released this week.  2.1.5 filled in
    security holes which affected sites which allow untrusted users to
    create DTML documents.  Ironically, a bug-fix which was included
    in 2.1.5 broke code which depended on the bug.  This was fixed in
    the second release, 2.1.6.

    http://www.zope.org/Products/Zope/2.1.5/Zope_215_release
    http://www.zope.org/Products/Zope/2.1.6/Zope_216_release

  * Thanks to Eduardo Fernandez Corrales, the Zope Weekly News is now
    available in Spanish!  He is publishing translations at Zope
    Hispano, a portal for Spanish-speaking Zope developers and users.

    http://zope.sistelnet.es

  * Healtheon | WebMD is hiring in Atlanta, GA

    Healtheon | WebMD is looking for Software Engineers with
    experience in Python and/or Zope to work in our Global News Center
    located in Midtown Atlanta, GA. You must be willing to relocate.

    http://www.zope.org/Members/kbirch-webmd/hiring-notice


New Products

  * The Portal Toolkit has been packaged into a snapshot release for
    use by those who do not have access to CVS.  The PTK is targeted
    at community-oriented portals, but is also appropriate for any
    site which wants to give members a personalised view of content.
    The snapshot release is 0.7.1.

    http://www.zope.org/Products/PTK


Updates

  * Software Product: load_site.py with additional features, by Itamar
    Shtull-Trauring

    Itamar has updated his powered-up 'load_site.py' again.  The
    present release is 1.3.1.  This update adds a GUI, built with
    wxPython.  'load_site' is a utility for dumping content from a
    file system into the ZODB.

    http://www.zope.org/Members/itamar/load_site

  * Software Product: ZopeEDIT, by "jimbag"

    The latest release of this product, 0.0.5, adds limited RPC
    support which is used to create and delete folders.  ZopeEDIT is a
    tool which enables any text editor to edit content on a live Zope
    server.  It does not need to run on the same machine as the Zope
    server.

    http://www.zope.org/Members/jimbag/ZopeEDIT/

  * Software Product: LocalFS, by Jonothan Farr

    Version 0.1.6, the Ides of March release, fixes several bugs, is
    more robust about determining file types, and creates XMLDocuments
    and StructuredDocuments automatically, where appropriate.  LocalFS
    is a product which allows Zope to serve files out of a local
    filesystem.

    http://lists.zope.org/pipermail/zope-announce/2000-March/000130.html

  * Software Product: SiteAccess, by Evan Simpson

    Evan has release version 1.0.1 of SiteAccess.  This version fixes
    a bug which interfered with FTP access to Zope.  The SiteAccess
    product allows Zope to serve different content depending on the
    hostname the site was accessed by.

    http://www.zope.org/Members/4am/SiteAccess

Zope.org items

  * How-To: VersionFTPServer, by "htrd"

    This How-To describes modifications to Zope which allow you to
    work within a Version through FTP.  Versions allow you to stage
    changes to a Zope site by effectively forking the database.
    Changes that you make in a Version are not publicly visible until
    you ask them to be.

    http://www.zope.org/Members/htrd/howto/VersionFTPServer

  * How-To: How To: Use GenericUserFolder with an SQL database Version
    1.1, by "hippy"

    This How-To shows how to customise GenericUserFolder(GUF) to use
    an SQL database as its repository for usernames, passwords, roles
    and anything else you want to store about a user.  The update adds
    information from Dennis Baker to help get things going with MySQL.

Midgard is a PHP and MYSQL integration.  Midgard uses MySQL the way Zope
uses ZODB, as well as relying on MySQL for the things that Zope can use
other databases for.  I would assume that Midgard is a logical step for
those coders that are used to making database-driven dynamic web pages
with scripting languages, and is probably intimidating to those that
don't come from that background.

On a brief overview, Midgard seems to want to exert more control over
your approach to content.

[snip questions I can't answer]

> Which features does Zope have that Midgard does not have?

Well... Zope is object oriented, transactional, can interface with a
variety of databases, uses and is written almost entirely in python. 
The web-management seems more robust, but I could be out to lunch.

> PS What does "Midgard" mean (I'm italian...)?

Midgard (should be Midgaard or Midgĺrd) is the Norse word for the
material plane, as opposed to Asgĺrd (the realm of the gods).

but be careful, since this is a security hole.  the executed command line

Hi,

The company I work for is getting into Zope hosting.
We're based in the UK and are pretty open minded since we've started doing a fair bit of work in
Zope ourselves.

If you or anyone else is interested in European Zope Hosting with a flexible, open-minded ISP (of
course, I would say that ;-) then contact 
Simon Coles (simon@nipltd.com) or myself.

Hope this helps,

Chris

I messed around with this a little bit before giving up, though I'd like it to
work....

The problem (as I see it), is that 1) you have to get to the data and 2) you
have to format the data properly so that the database stores it properly.  What
I've gleaned is that the binary data will contain characters that confuse
whatever DA you're using (I use the ODBC adapter).  This means you'll probably
have to replace these 'confusing' characters with their 'safe' counterparts.
For the person who got it to work, it was the 0x08 character.  I believe other
DB's will choke elsewhere.  I never could figure out which characters needed
replacing and with what, so I wrote an external method to save the file and just
wrote the filename/location/upload info into the database.

This wasn't as nice as I wanted (I had security concerns putting anyone's files
on the hard drive), but it will probably work (I get sidetracked once I got the
file saved and haven't finished that project).

Let me know if you get it solved (I'm using ODBC to a cheap acess database).

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

Marius Kjeldahl

I use Rackspace.com which is certainly not as cheap as other hosting
providers but for under $200 you can get a fully dedicated 350 MHz, 64MB
RAM, 8 GB HD and RH 6.1. So, in the end you pay about 2 to 3 times what
another hosting provider has but it is your machine. You can install
whatever you please, configure it to your hearts content and never have to
worry about what someone else will say. Zope loves its own machine.

I have found their support to be great and they do a 24 hr turn around for
new accounts.

Worth every penny (twice the penny if it is for your company).

I think the best analogy is to think of ZSQLMethods, ExternalMethods, and
PythonMethods like "normal" functions in C:  they receive information via
arguments, and acquisition is always done via one of the explicitly-passed
arguments.  DTMLMethods/Documents are in some ways more like C macros:  they
grab information from the surrounding DTML context, without having to be told
what they can "see".

The analogy breaks down at the "call site":  Zope looks at the explicit
parameter lists and tries hard to match arguments to any parameters which are
not explicitly passed by the caller:  normally, it does this by looking them up
in the REQUEST object, *not* in the current DTML namespace.  Therefore, whenever
calling a non-DTML method (External/Python/ZSQL/...):

  * poke all interesting values into the REQUEST object before calling::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-call "REQUEST.update( { 'bar' : 42, 'baz' : 3.1415926 } )">
     <dtml-var foo>

    This version has the advantage of avoiding the "expression" syntax
    of DTML, but does require polluting the REQUEST namespace (may be
    an actual advantage if multiple methods use the same values).

  * pass the values explicitly, using positional arguments::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( 42, 3.1415926 )">

    This version looks most "natural" to a programmer, but is fragile WRT
    changes in the parameter list (changing the order of parameters on the
    method silently breaks this call).

  * pass the values explicitly, using keyword arguments for clarity::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( bar=42, baz=3.1415926 )">

    This version, which I prefer for any method taking more than one argument,
    says explicitly what it is doing, and therefore eases maintenance.

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985FA@pces.cadlab.it>

Python is quite slanted toward this kind of applications:
1) very clear sintax (many webmasters are not particularly fond of C and
Perl, like me...)
2) strong support for string management and a very good regular expressions
module
3) wide choice of modules for interfacing with web servers, mail servers,
database, etc...
4) ready-to-use modules for HMTL, Mail messages and XML manipulation
5) tons of good documentation, examples and a very active community
6) hard-rock core system and reliable modules
7) indipendence from the platform (Python runs almost everywhere. I'm
re-compiling it for my Z80-based microwave oven...;-)

Despite this, I think that the real reason why they decided to use python
was the terror to commit a mortal sin (like touching a Perl interpreter) and
the desire to live immersed in the light of the true Faith. 

I would have done the same...

This is great, some light at the end of a very dark tunnel.  One
question here:

How where you able to get strace to work?  I've been trying and it
either would lock Zope up or just return instantly.

Yes, we noticed that to.

Is this only when accessing via FastCGI or does happen when using
ZServer as well?

Thanks for the info.  If we find anything out I'll let you know.

My advice here is not based on work with Zope, but on years of painful RDBMS
experience:  I do *not* recommend storing large BLOBs in any existing RDBMS --
they aren't built for them, and generally make your life miserable when you
try.  Most of the reasons you would choose to use an RDBMS (performance,
replication, stability, searchability, etc.) don't apply when it comes to large
BLOBs;  you are still much better off storing the "BLOB" in a filesystem
somewhere, and then storing a path/URL to it in the RDBMS.

With Zope, BLOBs present another issue:  because they aren't standardized, each
RDBMS has a proprietary API for BLOBS;  the Zope database adapter therefore has
to have custom code for each RDBMS, making the BLOB code one of the likeliest
sources of weird, hard-to-reproduce bugs I can think of.

In short, *don't go there*.  Really, I'm serious.

Tres.

P.S.  If you *have* to go there, use the Python base64 module to encode
      binary data.

No such decision was ever made. When Paul Everitt and Rob Page founded Digital
Creations (a history I know only from Paul's and Rob's telling me, I could
well be out for lunch on this), Paul was getting quite heavily into Python
already. He convinced Rob that it might be a good language to base their
development on.

They then hired Jim Fulton, then already a very active Python contributor (he
hosted, if IIRC, the 3rd and/or 4th python conference or something). Under his
technical guidance software was developed that only in November/December 1998
came together to form Zope.

Many parts of what is now Zope, like Bobo (predecessor of the ZODB), DTML
Templates, Extension Classes and Acquisition where already Open Source, and
heavily used by the python community. When Zope came to be, all those parts
were mixed with things like Acquaduct (now database adapters and ZSQL
Methods), and Principia (now the web management interface and many of the
stock Zope objects like File and Folder), that were commercially sold by
Digital Creations.

So, python made Zope and its power possible. If you now decide that you want
to go and build Zope in a different language, you will first have to try and
build all those parts from which Zope came to be. And this will be pretty
hard, if not impossible. Pythons clarity, OO orientation, extensibility and
last but not least Jim's technical excellence with python will be greatly
missing.

I think it had to more with Jim Fulton's "zealos object-orientedness" than
that -  Zope is a system for publishing python objects on the Web.

I suggest that you negotiate with service provided over the terms of the
service agreements. You might find that they are more flexible than their
web pages indicate. Or you may influence them to change the standard service
agreements. I use CodeIt Computing and am happy with their service.

The implementation I sketched out a version of the Prototype pattern, I think. 
Exposing the customizable bits is more like a TemplateMethod:  this would play
nicely with Acquisition, perhaps::

  <!-- Inside the index_html method of a "folderish" ZClass -->
  <dtml-if custom_foo>
    <dtml-var custom_foo>
  <dtml-else>
    <dtml-var default_foo>
  </dtml-if>

The trick then becomes giving the manager enough information to know how to
implement 'custom_foo'.  My current hack solves this by cloning the default bit
as a starting point -- perhaps the factory could clone 'default_foo' as
'sample_custom_foo', or something?

Based on previous e-mails here, I have read that Zope does not support
server-side includes.  Is there a way to get around this in reference to
an img src, as in the following:

<img src="myprogram?-action=gif&amp;yadda yadda yadda>


Basically what I have here is a page that includes other documents (maps,
graphs, etc.) via server-side-includes.  If there isn't any way around
this, then I may have to forgo Zope for now...too much of my system
depends on this sort of thing.

The example for finding items to catalog doesn't work for me.  When I enter
getNodeName()=='entry' in the 'expr' field I get the following error:
 Error Type: NameError

Message-ID: <B059671903C6D211A0D500C0F0301C792B2714@kubrick.mop.no>

Adding a SiteRoot object to some folder upward from a ZDConfera topic
("Confera Topic" object) will break the topic.

It seems that when adding a message, instead of inserting a valid
message object, ZDConfera ends up adding a corrupt object. At one point
ZDConfera, when I tried adding a follow-up, duplicated the parent
message instead of adding the reply, resulting in a circular reference
that only a database restore would fix.

This is Zope 2.1.4, SiteAccess 1.0.1, ZDiscussions 0.2.0, on Slackware
Linux 2.2.

Here's the traceback.

I would like to know why the following happens, and what I can do to fix
it:

I have a ZCatalog instance in my root folder called Catalog. I have some
CatalogAware ZClasses that get added to it automatically.

The problem is, when I query Catalog for results, it only shows the
elements that were present the last time I clicked the "Update" button in
ZCatalog. The new elements are present in the catalog, but they don't show
up in the query until I manually update the catalog.

Here's the query code:


<dtml-in "Catalog(meta_type='Track', track_hasfile='on',
track_active='')">
  <li>
  <a href="<dtml-var "Catalog.getpath(data_record_id_)">/approve">
  <dtml-var "Catalog.getpath(data_record_id_)"></a>
</dtml-in>

Any help appreciated. Please CC me if you answer.

Here's the scenario that I'm dealing with (all of this works w/o Zope,
i.e. static content):

  - user starts at www.mydomain.edu (http)
  - user goes to www.mydomain.edu/internal which is secure (https) and
    requires a password for entry
  - all pages under www.mydomain.edu/internal are secure (https)

I'm having trouble getting this to work with out Zope-ified site, however.
What I would like is to have Apache handle all password authentication, and
I would like it to happen over ssl.  Is this possible at all?

Any help would be appreciated.

Thanks in advance,

Just a few thoughts.

Simple workaround: make the id field unique. it would seem to me that
you could then use a try/except clause that tried to insert the data
into sybase, and redreate an id if it failed due to the id already
existing.

Additional options:
 o add a randomly selected letter (or two) to the numerical id. Now the
odds that any two servers, or a change in time, will obtain the same key
are extremely slim.
 o Randomize the order of numbers in the 'timestamp'

Combine these with the unique restriction above, and you should have a
_very_ scaleable, an relatively easy to implement, solution.

Subject: [Zope] Casting to a list
Message-ID: <38D91168.F163496@messagemedia.com>

Another question (soon I'll start answering more on this list :) - I
have a set of checkboxes with the same name that I iterate through
using dtml-in. However, when only one checkbox is checked, dtml-in
complains that a string cannot be used as input, it expects a
sequence. My initial thought was to do this:

<dtml-if "type(var) == type('')">
  ... (do not iterate)
<dtml-else>
  <dtml-in var>
    ...
  </dtml-in>
</dtml-if>

How can I either cast a string to a list w/o messing up an existing
list, or gain access to Python functions such as type() from a
dtml-if statement?

Zope in a sense replaces server-side includes with <dtml-var>.

What you need to do is upload the images to Zope in whatever folder
is appropriate. To do this, select "Image" from the create item menu
found at the bottom of your Zope "Contents" screen. Select the images
you would like to upload, and submit.

The images will then be in your object hierarchy.

You can reference them using either
  (1) Manual <img src="...">
  (2) Using dtml-var (the Zope way of doing things)

Say, for example, you uploaded an image called foo_jpg (Zope does not
allow dots in object names). You could reference it from any object in
the same folder as the image or nested folders using dtml-var

	<dtml-var foo_jpg>

Zope will automatically insert the height and width attributes and so
forth. To remove the border, you would use...

	<dtml-var "foo.jpg.tags(border=0)">

(I think)...

There are some interesting HOWTO's on this topic at zope.org.

I quess Zope is more "object-oriented" as it is based on an OO language.

OTOH, said OO language itself has been implemented in OO and non-OO 
languages (java and C) ;)

Probably the less flexible one ;) I don't know which.

There is currently a 2 Gig native (Zope internal) database size limit. 
This won't apply when you use external database or sore files in file system.

Bot are wll supported on Zope. Dunno about Midgard.

Zope has integrated a lot, so does PHP - you probably find most popular 
"other technologies" supported/supportable on both.

Probably Zope (this is a Zope list)

The one you know better :-p

I guess they are about the same. The one that will be used more will 
eventually be safer due to more eyballing.

Both can be configured to be insecure ;)

Howdy everybody.  Last night at the Bay Area Linux Users Group meeting I
announced that we are going to make ZEO Open Source and thus a
first-class feature of the Zope platform.  For more information:

  http://www.zope.org/Products/ZEO/

Some quick notes:

  o A first release for a very small, qualified group of testers will
happen mid-April

  o General release some weeks after that

ZEO (Zope Enterprise Option) turns Zope into a *distributed*
transactional object system, allowing people to add processors,
machines, and networks to scale their web applications.

Ok,  I've butchered the original message because it was too long to read.
It looks like Proxy Pass is the best way to go.  Can you use Proxy Pass with
SSL?  ZServer alone is not a choice because SSL is a requirement.

You know after reading this thread I was pretty surprised that we didn't
have simply execcgi ability in Zope, considering how trivial it is.

I'll look into something like this possibly being a feature.

It sounds like this is probably coming from an SQL database? If it is
modify the query you're using to sort on the DBML-side. If your
query looked like:

	select * from books

You would modify it. Having mutliple levels of order by varies from
DBMS to DBMS, but it'll look something like this:

	select * from books order by book_name, id

Or something to that effect.

Sorting using the DBMS is more desirable as well because the DBMS
is likely to sort it more quickly, with all its indicies and so
forth.

If you tell me which DBMS you're using, I probably know exactly
what you should do to your query.

Ihis didn't work, then?  Looks better than what I came up with, which, for the
list vs. string situation goes like:

<dtml-try>
  <dtml-in string_or_list_var>
   list stuff...
  </dtml-in>
<dtml-except>
  non-list stuff...
</dtml-try>

If you have a string with multiple values to split, use the _.string.split()
function, as...

<dtml-in "_.string.split(str [,separator])">

This will probably choke on lists, though.  Combine the two for a wholesome,
good-start-to-your day breakfast code. :-)

This is less of a Zope issue and more of a DBMS issue (which is why I
can answer it)...

There are two ways to get global unique ID's:
  - Have a unique ID server
  - Find a way two servers can come up with ID's unique to each other
    without talking to each other. This is a lot of fun, and is done
    by using the network card's ID number, which is statistically
    unique. Basically, if you use the computer's network card ID, you
    can generate statistically unique ID's (this, incidentally, is the
    MS SQL Server way[*])

[*] I in now way indorse MS SQL Server. Please do not flame me for
mentioning it; I know it's a peice of crap. :)

The former is more elegant, but the latter is sometimes more practical
for distributed systems. At any rate, there is no simple solution to
this problem (many companies have had major research into this area
with little results). Your best bet is to keep this out of Zope and
just set up a unique ID server.

Have your databases (Sybase?) establish foreign links to the unique ID
server. Then, write triggers that grab ID's when rows are insert. Say
you had two tables, on two servers, that need to have unique ID's.
You would omit their ID fields upon doing an insertion, making them
NULL. You would write a trigger on insertion for these tables that
would detect the NULL id field, grab the unique ID from the unique ID
server, and insert the row with the unique ID.

In very large environments with lots of data importing, this can be
a large strain on the network and the unique ID server. If this is
the case, be sure to have good bandwidth between the servers. And
as always, bigger servers means more performance. :)

The simple answer is: you don't need to cast. :)

Zope provides a solution: your specify in your multiple-select
a name like varname:list, and Zope will automatically cast it
into a list. That is, append the ':list' to your variable names.

Thank you for your input..I think I need to explain myself a little
better, however.  I have no trouble with a static image...the trouble I am
having is with images created on the fly.


For example, I have a cgi program (which I would like to continue residing
in my linux structure.....static pages I would like to be in
my Zope structure).  This program will generate a graph based
on the time units, and whatever particular data sets I pass as parameters
to the program.  So, the image can't be stored on  Zope, since the image
may be different each time it is brought up...for example, I have the
ability to pass the word "today" as a parameter...this means that
everyday, the graph generated will be different.  Is there a way for
Zope to respond to a cgi program that's being called as "img src" value?


Thanks,
Jessica

My understanding from a recent discussion was that it happens on all platforms 
with 32-bit ints regardless of weather they support large files or not.

does ZDB use longs internally and just some small part strangles it to 32-bit,
or is it something more widespread ?

Message-ID: <B059671903C6D211A0D500C0F0301C792B271A@kubrick.mop.no>

I use identity columns with Sybase -- the only problem I've experienced
is a tendency to occasionally "burn" ID values, resulting in gaps.

If you're not worried about non-sequentiality, identity columns are
generally not a problem. Do you anticipate crashes? I have run Sybase
for about a year, and never experienced a single crash -- meanwhile,
Zope has crashed and/or been restarted many, many times.

Aside for identity columns, here's an alternative scheme I used some
time ago with an  Access database (where, aside from DAO/ADO, you simply
cannot obtain the previously inserted "autoincrement" value, causing
problems for web-based forms): Create a table such as this

	create table Ids
	(
	  Id int
	    not null
	    primary key nonclustered
	)

Then create either a stored procedure (don't like 'em) or a Zope DTML
Method that will (a) get the lowest available ID, and (b) if the table
is getting empty (count < delta), then replenish the table with new,
unique values, starting at the ID you just obtained. (If the table is
empty when you start out, assume this is the first time the method is
run, and simply start with a seed of, say, 1.)

Because of transaction logic, IDs will never be "burned", and the only
gaps you will experience will come from IDs that disappear when their
parent records are deleted.

Hope this helps.

Hi there,

I'm trying to connect to an Oracle 7.3 database through Zope using a 'Z
ODBC Database Connection'.
It's giving me an error saying:
'Invalid connection string: gsmInfo'

I set up a DSN throught the Control Panel as follows:

Data Source Name: gsmInfo
SQL* Net Connect String: 2:
UserId: testowner

This is using the 'Oracle73 Ver 2.5' Driver.

I also used the '32-bit ODBC TEST' that comes with Oracle and this
connected to the database no problem after entering in a password.

Has anyone got any clues or suggestions to the problem.

Thanks in advance,

Michael Gannon.

Subject: [Zope] img src (newbie)
References: <Pine.OSF.4.02.10003221254190.24303-100000@batman.tamucc.edu>
Message-ID: <38D929CF.42FD9EBB@messagemedia.com>

So, you have a CGI script that dynamically creates an image as its
output. You'll either need to re-implement this using Python and make
a ZOPE product, wrap it using a Zope product (which seems the least
elegant), or just keep it out of Zope (probably the desirable). I
assume you're running apache and using Zope.cgi, so your Zope path
is

	http://yourhostname/Zope

Now, your CGI scripts are under:

	http://yourhostname/cgi-bin

You'll just want to reference the images just like you would in
normal HTML. Zope will not mess with an img tag, so if it points
to a working CGI script, you're ok.

Does that answer your question?

Subject: [Zope] Role weirdness
Message-ID: <m3em92zrw9.fsf@wacko.pdx.net>

I have a site containing some content users need to register to see.
The way I set this up was:

/premium/acl_users[GUF]
Using GUF to authenticate and assign users a role of
contentSubscriber.

At one point in time, I created a user defined role at the root level
of my Zope called contentSubscriber.

I then changed the security on /premium to require contentSubscriber
role to view or access content information.

Now, I can't seem to find any mention of a contentSubscriber role
anywhere in my Zope management screens OTHER than by looking at a user
through /premium/acl_users/userList.

None of the Find/Advanced... screens mention my contentSubscriber role
either.

The odd thing is that my access control scheme appears to work.  Other
than my random hourly crashes.

That doesn't look like a valid connection string. Usually, the connect
string is something like:

        user/password@sid

At least using the normal Oracle interface. SID, which I assume would
map to ODBC would be the datasource name defined in your tnsnames.ora
file.

You might try testowner/password@gsmInfo

Or consult your ODBC docs on proper connect strings.

Sure.  I'm using mod_ssl and apache 1.3.12:
My conf is like this:

<VirtualHost 216.17.170.666:80>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
</VirtualHost>
<VirtualHost 216.17.170.666:443>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
   ServerName imeme.net
   ServerAdmin mindlace@imeme.net
   ErrorLog /path/to/apache/logs/error_log
   TransferLog /path/to/apache/logs/access_log
   SSLEngine on
   SSLCertificateFile /path/to/apache/conf/ssl.crt/server.crt
   SSLCertificateKeyFile /path/to/apache/conf/ssl.key/server.key
</VirtualHost>

I have zope actually running standalone on port 6666.  Then I use
SiteAccess.
The access rule should look like this for you:

look for internal, then munge the result to be 0 if not found:
<dtml-if "1+(_.string.find(PATH_INFO, 'internal'))">
  <dtml-call "REQUEST.set('SiteRootBASE','https://www.mydomain.edu')">
<dtml-else>
  <dtml-call "REQUEST.set('SiteRootBASE','http://www.mydomain.edu')">
</dtml-if>

then you want to put a SiteRoot object in your root folder, leaving
everything as per default.

As long as your first links to /internal are written as https:// the
austhentification should be over ssl. The access rule makes sure any
dynamically generated URLs under /internal are written as https://

Subject: [Zope] Roles, Local Roles, and so on
Message-ID: <20000322213020.A16021@owl.rhein-zeitung.de>

Hi,

I have a question concerning the Role and Local Role system. Well, am I right
with the observation, that Local Roles are only locally assigned global roles?
For example I have an user "oandrich" which is globally just a member of Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to get
really local roles?

Bye, Oliver

emphatically yes- see my message to Erick Mechler re: httpd.conf help.
There are some complications with virtualhosting, because zope only sees
whatever it's listening to, so you have to have a different
<virtualhost> directive for every virtual host as opposed to just
letting zope handle virtualhosting.

phew.

I use a wrapper sql method called UserSettings.

Any calls to data are wrapped in a call to UserSettings eg.

<dtml-in UserSettings>
...
</dtml-in>

UserSettings SQL is : "select * from online where username=<dtml-sqlvar "_.str(AUTHENTICATED_USER)" type=string>"

The online table has columns for data (user name , etc) as text and memos  and permissions (is_super, edit_media...) as logicals
(True/False)

I use the returned information to decide whether an item is displayed or how it is displayed.

No, its a dtml-in for a ZCatalog.
Can I pre-sort the catalog for one MetaData field, and sort the dtml-in
for the other one?

Or are their any easy ways to modify the dtml-in tag to handle multiple sort fields?

Note that the version I posted has several rough edges:

 * It doesn't propagate the CGI environment to the child process.  We
   could fix this on Unixen by doing a fork() and some execve() magic,
   but then we lose the convenience of popen();  CreateProces() on Win32
   requires special handling, too.

 * It doesn't propagate the input stream some CGI's may expect to find.
   "Temp files and fork() and dup(), oh my!"

 * Win32 versions to use the win32.popen(), instead of os.popen().

 * The error handling is ugly.

 * It double-buffers results (which could get ugly if the CGI does
   weird stuff, or returns a really huge result).

In short, its a pretty ugly bandaid, recommended only for easing the CGI
withdrawal jitters. :)  Doing the Right Thing (TM) involves reimplementing a big
chunk of a web server, which is probably why Zope Didn't Go There already. 
mod_rewrite looks pretty sane by comparison.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A09A@express.sematech.org>

I have a dtml-method page that displays a table of values and allows the viewer
to delete on of them (using an sql method on the next page).  All works as
expected, but I noticed an odd thing:  when I used the back button on the
browser the table of values was not updated, but showed the old values.  This is
bad, because people will think their delete did not work.

How do I force a page update?  I checked the IE5 options to make sure it was
checking the date stamp on every visit, so I don't think it's a cache issue,
though I don't know enough about browsing to say it isn't.  Shouldn't forms be
re-submitted on the back button?

I'm sort of confused how this is all handled....

Environemt propagation after a fork wouldn't be too hard, and I was
kindof assuming punting on Win32.

There wouldn't need to be much, just catching errors from the Zope side
code, anything the CGI raises is it's own problem.

I strongly suspect that this is a symptom of a known (to me) incompatibility
between SiteAccess and ZCatalog.  If ZDConfera uses a ZCatalog to track
topics, it will not be able to retrieve them correctly.  I have a patch to
ZCatalog to fix this, but it hasn't been tested by anyone but me.  It just
replaces the resolve_url method of ZCatalog with one that doesn't reenter
ZPublisher.  If you're willing to test it, I'd be happy to send it.

Subject: [Zope] How do I get the owner of a document?
Message-ID: <20000322224211.A16366@owl.rhein-zeitung.de>

Hi,

may be I am just to dumb or something like that, but Zope has to now who is
the owner of a certain document. This is for sure, but how can I get the owner
of a document from DTML or an external method? I read through the sources and
maybe I am just to dumb or so to find it, but I can't find any manage_* call,
that tells me how to do this?

I have to write a small DTML method, that finds all documents, that are
located in a givben hierachie which are owned by a certain user.

Bye and many thanks,

    OLiver

P.S.: Don't frustrated that I ask these things again and again, but now I have
to deal with things in Zope, that I haven't dealt with before. ;-))))

Please send me the patch. The problem does not seem to have anything to
do with URLs, but rather the objects indexed by the topic -- but I could
be wrong here.

Is there a way to modify ZDConfera/ZDiscussions to fix the problem,
without patching ZPublisher? I wouldn't want to break something else in
the process.

I think maybe the issue got clouded by the phrase, "server-side includes".
What you are asking for is not a server-side include:  you want to generate a
tag in Zope, something like:

  <img src="build_graph?units=hours&series_a=hit_count&series_b=load_factor">

This isn't SSI because the browser makes a separate request for the image,
after/while loading the page containing the tag;  SSI is massaged by the server
before the browser ever sees the text.

That said, it *is* feasible to build a parameterized image link, using exactly
this kind of syntax.  There are a couple of contributed products which do
on-the-fly image generation:

  * "gdchart":http://www.zope.org/Members/teyc/ZGDChart 
 
      "draws charts using data from your ZSQLMethod"

  * "TTImage":http://www.zope.org/Members/RainDog/TTImage

      Converts text strings into a GIF/PNG/JPEG images using
      TrueType fonts.

I may have even missed one -- check out the "Zope
Products":http://www.zope.org/Products page.

Without patching ZCatalog, you mean? Hmm.  Possibly.  If ZD* were patched to
use a subclass of ZCatalog which overrode resolve_url, that would work.
Here's the replacement resolve_url for ZCatalog:

    def resolve_url(self, path, REQUEST):
        """
        Attempt to resolve a url into an object in the Zope
        namespace. The url may be absolute (site-relative) or a catalog path
        style url. If no object is found, None is returned.
        No exceptions are raised.
        """
        pparts = filter(None, string.split(path, '/'))
        try:
            obj = getattr(self.aq_parent, pparts.pop(0))
            while pparts:
                obj = obj[pparts.pop(0)]
            return obj
        except:
            return

Yes, most browsers do this.  It's simply a result of their caching.

The only way i know of involves catching hits to the back button involving
JavaScript.  Not pretty, IMHO, nor terribly portable.

Message-ID: <B059671903C6D211A0D500C0F0301C792B2722@kubrick.mop.no>

If the object inherits from CatalogAware, you get a bonus method called
owner(), which you can call like so:

	<p>The owner of this document is <dtml-var owner>.</p>

If not, you can use the get_local_roles() method. You need to iterate it
-- best with an External Method. Like so:

	def GetOwner(self):
	  for Role in self.get_local_roles():
	    if 'Owner' in Role[1]:
	      return Role[0]
	  return 'Zope'

Add this External Method at top-level. Then, thanks to Acquisiton, you
can access the value in any document thus:

	<p>The owner of this document is <dtml-var GetOwner>.</p>

Hope this helps.

Yikes, just noticed this one sat in my outbox unqueued :

Going back a month, just have to say thank you Chris.

It does work - I was getting the earlier error messages due
to being a bit ambitious and trying to display all of the 
images.

Just for the record, to get it to work :

1. Create a ZSQL method <ZSQL_SelectPicture> to extract the binary data 
   field ('picture') of one (1) image. That's the important part - one 
   single image.  Don't try to select several records for further logic
   processing.

2. Create a DTML method that returns nothing more than the 
   BLOB data from the ZSQL method, with the correct content type.
   Eg. 
  <dtml-call "RESPONSE.setHeader('content-type', 'image/jpeg')"><dtml-in
ZSQL_SelectPicture><dtml-var picture></dtml-in>

Accessing the DTML method directly will return the image.

This is stunning news.

Still absorbing this, but I think this will have ...interesting... ramifications for Zope in the marketplace.

From the Fact Sheet
"In summary, the ZEO architecture provides the power, flexibility and intelligence needed for the most demanding web applications."

and to think I wasn't going to check my email tonight.

thanks Paul!

Subject: [Zope] Use of Zope for data entry intensive app re-write
References: <38D950FC.F6B7CE47@voyager.net>
Message-ID: <38D96220.DCCD37EE@digicool.com>

I would imagine so... DC has written apps that handle intensive data
entry.. Zope gives you stuff like a security framework, a relational
database interface, a built-in object database, a document templating
language, undo, remote procedure calls from other machines, more.   

But the number of "screens" your application owns isn't really enough
information on which to provide a meaningful judgment.  Does your
application require delegation of authority?  Multiple security levels? 
A management interface?  Personalization?    Would it benefit you to be
able to run the app on multiple platforms without source code change? 
Does XML-RPC buy you anything?  Does FTP access to the ZODB buy you
anything?

Additionally, in the end a decision should generally take in to account
to how comfortable and familiar you are with a product.  If you're new
to Zope, Python, and OO, and you're under the gun to get this project
done and meanwhile you have 7 years of Perl experience, you may want to
seriously consider using Perl.  On the other hand, if you're curious
about Zope, Python, and OO, and you want to get some experience and
you're not tied to anything else in particular, Zope starts to look
really attractive.

Arghh... I should have been more clear, hopefully
someone else already has told you in the meantime,
but if not, the colons should be in the HTML FORM
fields, not inside the target DTML method.

That is, if you have check boxes or multiple select
form-input-elements, you would use something like:

<input type=checkbox name="mychoices:list" value="myvalue1">
...
<select name="mychoices:list" multiple>
<option>
...

Inside DTML, you would just use the name "mychoices" without
the colon. Something like:

  <dtml-in mychoices>
   <dtml-call "qryCAssign(user_id=_['sequence-item'],
                          client_id=client_id)">
  </dtml-in>

If qryCAssign() is a DTML method instead of an
external method, generally you would need to
prepend (_.None, _,... ) to the argument list.
That is, qryCAssign(_.None, _, user_id=.......)

Stable and functional.  It is being tested on several projects.

No.  These are very deep issues, especially the replication part.  If
this is important to you, I suggest using a replicated filesystem to
store the final FileStorage file, like Coda or Intermetzo.

While it would be a great idea for there to be failover and replication,
the issues are complex and without more wide spread use we really don't
want to start engineering a solution (one of the reasons we are open
sourcing it...)

IE will show a cached page, regardless of the settings, when hitting the back button.
If you were to type in the URL, it might actually get the page, but you can never be
too sure with IE.  Its cache is terribly misbehaved.  Try making the page uncacheable
with a Cache-Control: no-cache header.  To verify if this is the problem, hit
ctl-reload in IE (shift-reload in netscape) to force a reload of the page.

This should work (untested):

Some sort of transaction log would be nice. Not only could you track this

on my part.

Paul teased greatly last week with his announcement about a BIG
announcement he was going to make at BALUG. I was going to be out for the
day and not able to keep up with the mail but before I left I checked mail
hoping there would be news as to what it was. Alas no such fortune.

I get back and WOW! This is absolutely tremendous news.
Major, major thanks to all at DC, especially those that pulled the trigger.

I agree that this does set Zope apart from the others. It also set DC apart
from the others in their willingness to do a very good thing.

May DC be greatly blessed and prosper mightily because of the gracious
giving and contributions to the best open source web platform out there.
Once again mucho gracias.

This should be fairly easy to do by creating an external method that calls your
program, then calling the external method using dtml.

Just to nitpick, that isn't true. Zope object ids can contain periods, but it
makes it a pain to refer to those objects in Python expressions. -jfarr

Just for the record, I dont' use FastCGI and have seen Zope
die under the same circumstances; ie. by disconnecting the 
browser mid-download of a (usually long) page. Fortunately, 
that 'client' has been me via the administration screens, 
but it does seem like a rather trivial DoS. 
But it seems that this only happens with certain types of
pages - I'm not sure which.

Unfortunately, I can't remember if this was when we were using 
PCGI or Proxy-Pass, but it was definitely one of the two.

Hearing that others are now experiencing the same gives me
hope: this could explain the crashes that we've been plagued
with for months (though I fear any solution will come too late
to prevent our switch to an alternative platform).
 
chas

ps. Weird thing : the most stable Zope installation I have
    is on NT. It never, ever crashes, despite being the 
    development machine (I wouldn't say that load is causing
    my production server to die b/c it happens under low load
    too).

It seems that a lot of sites (including mine) have problems with Zope's
stability but somehow not many people reported the problems, and I am not
sure whether DC was/is aware of them. Our most useful Zope component right
now is a script that checks our Zope server every 5 minutes and restarts
it if it is down. I have spend many hours debuging but I failed to find
anything sustantial. I am under the impression (but nothing more solid)
that one problem might involve the interaction of the select call and
signal handling or the python wrap around the select call. No proofs
though. Unfortunately like you I failed to convince people in my group to
use Zope for more ambitious projects because of the stability problem.

It may also be due to people using the ZopeMonitor on Unix, which
restarts Zope if it dies.

Even better, it is a part of Zope! :)
From z2.py:
========================================

  -Z path
    Unix only! This option is ignored on windows.
    If this option is specified, a separate managemnt process will
    be created that restarts Zope after a shutdown (or crash).
    The path must point to a pid file that the process will record its
    process id in. The path may be relative, in which case it will be
    relative to the Zope location.
    To prevent use of a separate management process, provide an
    empty string: -Z ''
===========================================

Basically, add the option, along with the requisite options, and there
you go.

the problem is not in your query-code, i guess ..

IIRC, the catalog-aware zclasses are indexed automagically
when created, but not properties you set after creation. So
when you search for track_hasfile='on' , Zcatalog doesn't
have that property indexed:

You'll have to add :
<dtml-call reindex_object> in your Zclass Constructor method
( if you change properties there)

like this :

<dtml-with "Zclass_name.createInObjectManager(REQUEST['id'], REQUEST)">
       <dtml-call "propertysheets.Propertyshhet_name.manage_editProperties(REQUEST)">
       <dtml-call reindex_object>
</dtml-with>

-
Another possibility could be that you haven't added
track_hasfile to your indexes in Zcatalog.
If it is just a on/off-flag (which it looks like from here)
, add it as a field-index..


For better information, check out the excellent Zcatalog /
catalogAware HowTos on zope.org..

try

                relation='uncle'>

When you use the double quotation mark, it processes the content between
the double quotes as python code to be executed.  Since there is no
python code called bob, it fails.  Putting single quotes treats the
value as a string.

Hi there,

Thanks all for your help.
I got it working by keeping my old configuration in the ODBC Control
Panel settings and using 
'gsmInfo testowner PASSWORD' as the connect string in Zope.

Cheers,

Hi,

A simple question, but getting a bit irritating...

How can I change the roles assigned to a user without knowing their password?

The form to do this has password fields which come up blank, and you can't submit the form without
filling them in.

I don't want to know what the user's password is anyway, I just want to change the assigned roles...
;-)

HSCH,

Subject: [Zope] Using a database connection from an external method
Message-ID: <38D9F99C.726D6D4C@funcom.com>

I'm still figuring out how to integrate stuff in and out of Zope, and
thanks to all the people who gave me the friendly advice that I should
stay away from storing blobs in databases (I kind of knew that already,
but guess I was to busy worrying about marshalling things in and out of
Zope).

Anyway, what I am trying to do now is create an external method that
will receive the REQUEST object with some fields AND the uploaded file.
This external method will insert a record into an SQL table and return a
unique ID which I will use for the filename for storing the image in the
local filesystem (I am not worried about LOTS of images in a single
directory - that can be solved by a more intelligent filesystem
[ReiserFS?] or by some clever directory indexing).

Assuming I am able to pull this off, it should be quite easy to pull the
image back in again using the LocalFS product or my own external method.

I guess the external method will be run in the same process and thread
as the Zope process itself, so I would really like to get hold of the
database connection from my database connection instance in Zope. 

From searching the lists, I have learned:

* How to get the ZODB instance using self._p_jar; but this is not what I
need. I need to get the database object for my MySQL database, not ZODB
* How to call ZSQL methods from external methods by simply doing
self.someZSQLmethod

The last method would probably work, but since adding something to my
database table really consists of a database insert, then getting the
unique ID returned and using this for stuffing an image into the local
filesystem, I would prefer to keep this all in the same External method.

So the question then is:

How can I obtain the database connection to the external database (the
"Z MySQL Database Connection" in my case)? And I do not mean the
connection to ZODB.

Thanks,

Marius Kjeldahl

You can specify ":list" in your checkbox code to typecast the input.

Here is a quick test. The list should display OK when one checkbox is checked.

<FORM method="post">
<INPUT type="checkbox" name="myList:list" value="First">First<BR>
<INPUT type="checkbox" name="myList:list" value="Second">Second<BR>

<dtml-if btOK>
  <dtml-if myList>

   </SELECT>
  </dtml-if>

This creates a user from python - nice, but doesn't solve my problem. I want
to be able to assign a property sheet of some sort to each user I create, so
I can store his/her local preferences on my site.

Does anybody have a clue on how to accomplish this?

Thanks for the suggestion, though.

Message-ID: <38DA05CD.7F089CCC@nipltd.com>

Hi,

I was thinking about putting my 'Changing Roles' problem into the collector as either a bug or a
feature request so I went and had a look.

It's REALLY hard to try and find out whether anyone else has done this before.
Not only is there not any real categorization of bugs/featrues within Zope (everything seems to be
'General') but neither the search or advanced search is documented.

Most irritating though was that it doesn't look like you can read problems unless they're been
solved, so although there were a couple of bug titles which looked like they could be what I was
talking about, they were all ***This item is under review*** so I couldn't check.

By all means flame me if I'm being stupid, but otherwise coudl someone help me out?

cheers,

Chris

Actually dots are allowed in object names. You can create a picture called 
"myPic.jpg" and insert it with <dtml-var myPic.jpg>.

However because of their special meaning in Python they make it more 
difficult to access objects in Python expressions from DTML.

Example, to access the picture title, you'd need to use :

<dtml-var "_['myPic.jpg'].title">

or (simpler but longer)

<dtml-with myPic.jpg>
    <dtml-var title>
</dtml-with>

Subject: [Zope] Roles, Local Roles, and so on


Hi,

I have a question concerning the Role and Local Role system. Well, am I
right
with the observation, that Local Roles are only locally assigned global
roles?
For example I have an user "oandrich" which is globally just a member of
Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available
below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders
of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online
admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is
no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to
get
really local roles?

Bye, Oliver


[RH]Oliver,

the current role system lets you assign roles from a certain object (you can
add them under the security tab).

You could also devise a method or a product that (manually) registers the
roles a user is entitled to (or already has, depending on the situation),
but that could get you turning in circles easily.

Rik

Would it work for you to create a folder for each user with id same as the
username?
You get a propertysheet with the folder for free. You could also make good use
of acquisition to display pages based on preferences.

The easiest option is simply to wait a bit til the PTK version is working. 
Or even help out yourself with this part of the code.  Otherwise, you can,
for example, create an SQL table (in gadfly) with the username as an unique
index and properties as other columns.

Okay, I've put this into the collector now (hence my complaints about the collector ;-)

I've got a proposal:

How about leaving the form as is, but if the password fields are blank, then don't change the user's
password?

I might have a look at coding this later today.

If I do, how do I get it into the CVS or back to DC in some other way that it'll make it into the
next Zope point release?

cheers,

I am not in a position to go into a testing program in mid-april,
however I think there are probably many of us who wouldn't or don't
currently qualify who would simply like observer status on a mailing
list or something. That way we can at least begin the learning process.
It also puts more eyes on the problem.

Your question addresses a fundamental lack in Zope.  Zope was developed
internally in a closed source fasion for years to address the needs of
paying customers.  These customers typically did not design applications
themselves, we did all of that.  Therefore, much of Zope's API is fairly
oriented toward specific directions and there are big gaping holes.

Don't let that discourage, you, there are big gaping holes in all
software.  We are working on a project right now to come up with a solid
undertanding of interfaces in Zope.  While this may seem like a simple
task, it is not, but we are working on it and we are making progress. 
Here, you have come upon a hole, there is a method that lets you do a
number of things in one call but there are no decomposed methods that
let you do finer grained tasks.  This kind of situation is common, not
just in Zope, but in lots of software where extensability is very
important.

Unfortunatly, this is a gnarly problem.  For example, if we decompose
manage_users() into a number of smaller methods, it would make sense for
us to re-implement manage_users() to use those methods.  But this
involves not only writing a bunch of new methods but also taking solid
proven code and discarding it for new code, based on even _newer_ code. 
This problem becomes almost nauseatingly dificult when you consider that
we could turn this process to all objects in Zope, Folders,
ObjectManagers, ZCatalogs... And while it may seem clear there should be
so and so methods to decompose to, we need to make sure we think hard
about issues like, should they be callable via XML-RPC?  Will this new
method reveal a security exploit?  etc...

I don't want to take the wind out of your sails, perhaps you could
suggest some improvments, all the code is there.  For now we are taking
small steps, document what is there, propose a framework for sensible
extension, and then fill in some of the gaps, and tear down some of the
cruft.  I will make a note of your question for when we get to security.

I totally agree, don't worry... no wind taken out of any sails ;-)

After all, Zope is free and there are plenty of (very) expensive alternatives that will have just
the same sort of problems.

Hope I can help at some stage :-)

Aye carumba, I haven't even been following this thread, not the most
useful subject line!

Ok, it looks like there are two issues:

1) some sort of FCGI issue which I do not have the capacity to reproduce

2) the same stability issue I am currently looking into.

The problem with 2) is that no one can reproduce it reliably (this may
not be true after I look at something someone sent me today, I'll keep
everyone updated) including myself.  I have pounded a half dozen
sandboxes with ab for hours and gotten nowhere.  No crashes.  Not a
single burp.

I'm, of course still looking into this, but I need more data from the
folks out there.

First of all, if you suspect that your Zope is dying and restarting
alot, run it in debug mode like this (unix only, sorry):

bash$ strace -f -e trace=none -signal=all python z2.py -D

See 'man strace' for the gory details.

obviously tune the parameters to z2.py to suite your needs.

What we are looking for here are SIGSEGV.  You'll probably see a lot of
SIGUSR1s, these are normal.

If you can get a SIGSEGV to happen reliably, _please_ let me know.

You'll have to roll your own form, and have it call manage_users on the user
object with the variable 'remote_user_mode__=1'.  For example::

 
<URL:http://server:8080/acl_users/manage_users?name=fred&submit=Edit&remote_user_mode__=1>

suppreses the password display (but it is still there in hidden input field!)

You aren't being stupid at all.  Here is the low-down on the Collector:

 * New items in the collector are immediately marked "under review" 

 * "Under review" issues can't be viewed until they get marked "in work"
   or some such, allowing submission of security-sensitive bugs without
   publicizing them to "black hats."

 * Most issues sit in the "under review" state far longer than the minimum
   time to triage out the security bugs; this is a lamentable corrollary to
   DC's short-handedness.

Fixing this problem would require adding to the Collector a new state,
"submitted", which then becomes the "show no details to black hats" state, and
sending off nightly emails of "submitted" bugs to the sucker^H^H^H^H^Hteam
member responsible for the Collector.  Moving the bug to "under review" should
then make it visible to outsiders in all its glory.

Hello everybody!

Please join me in welcoming Matt Burleigh to the Digital Creations
team!!

Matt joins us as our first (and sorely needed!) system administrator.

From Matt's man page:
"""
I call beautiful and historic Fredericksburg, Virginia my /home.
Fishing, hunting, and reading civil war history are my hobbies.  Don't
tell anyone but I've taken many tech support calls from a boat and even
lost a cell phone in the lake once.

In 1983 I got a 1200 baud modem for my 64k IBM PC and it was down hill
from there. Sometimes I feel like I spent all of my life in front of a
computer. I started the first BBS in the Fredericksburg area and a quite
successful one. Eventually becoming Central Virginia mail hub for
FidoNET and sucking Usenet newsgroup feeds off of a satellite dish then
divvying it up for the local area SysOps. Those Usenet feeds were from
this thing called the Internet, which took me by suprise in 1994. At the
time I was running a small computer sales and service shop in the area.

Once I realized that BBS's and RIP Script (a graphical language for
BBS's that was going revolutionize the online world, ha!) wasn't going
to make it, we switched our dial-up modems to direct connections to
ISPs.

In 1996 a friend of mine introduced me to Slackware Linux. This crude
operating system really intrigued me and I found it to be an exciting
new challenge. A couple months later I began selling used machines with
IP masquerading and firewall setups. Soon after that, I convinced a
customer of mine to switch from the ever failing Windows NT v3.51 to
Linux. The system ran for over 6 months with not one problem or required
reboot. I was hooked and swore never to install Windows NT again.
"""

You could try:
<dtml-call "RESPONSE.expireCookie('main_counter'">

which might work.

Hello all:

Not sure if this has been asked before, probably yes, but haven't been

Does any of you has been able to print from a Zope application to a
printer attached to the same machine where Zope is running, in my case
it's a Red Hat Linux 6.1 box.

I need to print from Zope with a specific printing format (like
invoices, receipts, etc).  This will be done on always the same Intranet
and printing will be controlled from the Linux spooling system.

If you can copy your comments to me by email besides the mail list, it'd
be great.

,Any help is appreciated, thanks in advance.

I am not usre what you need to do. The cookie name is SassionUID. If you
need to delete something from the FSSession data use FSSession.delete
like:

<dtml-call "FSSession.delete('main_counter')">

you can expire the cookie by ... reading Chris followup email (just

Message-ID: <Pine.LNX.3.96.1000323155356.11696K-100000@marvin.nipltd.com>

My saga with the standard_error_message continues ;-)

I'm trapping 404 errors for missing pages, checking the intended URL
against a list of URLs which have moved to new locations and returning a
link to the new location as part of the error page.

What would be useful would be to automatically redirect to a new URL if
it occurs, but this is proving a problem. I've been using
RESPONSE.redirect() as this has proved useful on other pages, but on
standard_error_message this doesn't appear to have any effect - even when
the entire contents of the error page is stripped out and replaced by just
the call to redirect().

Is it possible for standard_error_message to handle redirects (in which
case, what else do I need to do?) or is there another way to go about
this?


Thanks in advance.

John

Subject: [Zope] records form variable type
Message-ID: <wksnxh8xai.fsf@email.aston.ac.uk>

I have been using the records form variable type, but believe there
may be a problem with it. With most browsers all appears OK, however some
browsers (e.g. Mozilla) may return form elements out of order. What
this means is that when trying to use the records type their is no
guarantee that the different elements of a single record will be sent
consecutively and therefore the records objects will not be correctly
constructed by Zope.

I would like to know if this is the fault of browser or if this is an
issue which excludes the general use of the records type. If the
latter what alternatives would be recommended - I would prefer not to
have to create unique form element names as it would add a fair amount
of complication. 


What guarantees can be safely assumed about data arriving from a form
- for example if you try using the list type is the order in which the
components of the list guaranteed to be the same as the order in which
the respective form elements occur in the document?

Subject: [Zope] timing error in ZODB lock?
Message-ID: <38DA468F.898A2FFB@sage.att.com>

i'm getting some funny behavior using a (separate from Zope's)
ZODB from External Methods.  after much thrashing, i've got my
application working.  however, every so often, when i click 
on a submit button that invokes an External Method, i get:

   Could not lock the database file. There must be another process
   that has opened the file. 

the odd thing is that if i click the browser "back" button, then
hit my button again, it works.  occasionally i need do this
back/resubmit thing more than once, but usually once suffices.

smells like a race condition to me.
has anyone else seen this, or have an idea how i can avoid it?

http://www.reportlab.com/ may be what you need.  It's in Python, so it
should be easy to hook up to Zope, and it outputs PDF which can then be sent
to lpr for printing.  Since RH uses Ghostscript as a print driver the
generated docs should print fine.

I would favor making it like the HowTo list; where you can organize by
title, date, author, and reverse them. The code should be a basic

Just wondering if anyone has thought about personalization
services based on Zope ? 

The most obvious/traditional approach seems to be :
1. Acquire user information (via forms/surveys/transaction-histories etc)
   and store in RDB. 
2. When the user comes to the site (and either logs in or is identified 
   by IP or cookie), query the RDB for customized content or appropriate
   products. 

OK, no magic there. But it's not very scalable in terms of :
a) Load. We can keep shoving Zope servers on the front end
   but the RDB is going to get hammered if this has to occur
   for each and every request. 
b) Development. A more object-oriented approach would be nicer.
   eg. Personalities with behaviours and properties. 
   Could a pool of persistent personalities be left floating 
   around ? (No, this is not an early April's fool) 

A while back (1997) I saw Broadvision and didn't really appreciate
what they were doing. It seems that they've really improved a lot
since then but I can't get my hands on their software (not for free
anyway). So, I'm wondering if anybody has experience with it and 
can enlighten a heathen on key features we might wish to, er, 
'appropriate' in Zope systems ?  Or is it, like Vignette and Netscape
ECXpert, nothing special and you're basically paying for the 'knowhow' ? 

Thank you,

Message-ID: <002b01bf94e6$968a7af0$f2381bd8@LIPS>

hello:

i'm using Zope 2.1.6 and LocalFS 0.1.7.  when i try to view an image via a
LocalFS object i get an exception in OFS.Image.py at line 187:

last_mod =int(self._p_mtime)

the error occurs the *first* time i try to access a specific image with a
recently launched browser.  accessing other images or subsequent hits to the
troublesome image in the same browser do not cause the problem.  subsequent
hits in the same launch of zope from a fresh browser on another machine
causes the exception.

having modified Image.py to catch the exception and dump some information i
see that self._p_mtime is None.  i've looked around but cannot determine
where _p_mtime is defined or how it is supposed to be set.

i see this method in Image was re-written after Zope 2.1.4.

similarly, accessing a .wav file via LocalFS causes the following message:

2000-03-23T16:27:13 ERROR(200) ZServer uncaptured python exception, closing

the wav file is delivered to the browser correctly.

as a quick fix to the Image problem, i catch the exception, set last_mod =
0, and continue.  this does not seem to have any ill effects.

Subject: [Zope] ZWiki comments
Message-ID: <38DA502B.B20E8928@texoma.net>

For a previous message I posted to the list I was prompted to place a
comment in the associated ZWiki.

I went to the ZWiki to comment and played with the "Sandbox" before
posting to learn a few things. From the things I learned here are a
couple of comments I wanted to throw out. I know some of these run
counter to the thoughts of the Wiki community but they are concerns
nevertheless.

The nature of Wiki is very unsecured. This is for better or worse. I
know the ZWiki on the Zope site does require logging in before editing
which helps but does not eliminate the potential of malicious or
accidental editing.

Anyone logged in can do any kind of editing they wish on a page. They
can erase all text. They can insert, delete or otherwise modify comments
or content made by other people. These things can be positive or
negative depending on the goal or intent of the page.

I think editing a page is more applicable to stable open content than it
is to a forum oriented page.

Examples.

If Zope's documentation was managed by ZWiki in a secure manner then a
community member could make corrections of typo's or legacy information
like references to Principia, etc. The submit button could either be a
"Submit for review" or if really trusted "Change". I know this
duplicates somewhat what CVS does. Once again depends on goals.

If the page is forum oriented, i.e.: an on going conversation like a
bulletin board and such then it is more appropriate to "Add comment"
than to "Change page". This would present the user with a cleaner
interface and a clearer idea of what they are doing. They would not be
presented with the entire contents of a page so they could merely append
a comment on the end.


If the ZWiki on the Zope site starts getting busy we run into other
problems. The problems especially affect a forum oriented type page.
Just to learn I opened up the "Sandbox" in a new page, I then open the
"Sandbox" again in a new page. I edited the first and submitted and then
edited the second and submitted. The first was successful. The second
fortunately got an error message. I say fortunately because it did not
overwrite the previous submission.

In a busy forum or BBoard multiple people getting errors would be a bad
thing. If in a forum oriented page an "Add comment" button was available
then the conflicts and errors would be avoided. This would also enable
ZODB's transaction mechanism better with each comment being an object
associated with the page.

This would also be more secure in that people would adding their value
and not altering other peoples.

On Philip Greenspun's site  http://www.photo.net  the BBoard's are
somewhat integrated with email. You can subscribe to a bboard and
receive email for the added comments. This is a nice feature. Their
implementation is quite inelegant and could be improved. Zope/ZWiki
could shine here. This allows user to choose how they want to view the
messages, either through the web or via email.

Just a few thoughts to throw out to the community.

Actuatly, there may be one other quicker method to do this.  You can somehow
(i haven't tried this) compile php into a stand alown executable.  Then you
could then have an external method do a shell call running the php script.
Another interesting thing you could do would be to make a zope product that
stored php3 code, and then called out to php to parse it.  This might not be
a bad way to allow clients to have their own maintainable php3 scripts up
on the web without giving them ftp or shell access.  hmm..

I was thinking of a general simple caching product for Zope, to use in
conjuction with FSSession for high load sites. A simple implementation is
to use an in memory python dictionary to hold marshalled or cPickled data.
Since the access times are fast we could use the asyncore classes that
come with python to achieve really high rates. The cache contents can be
served from a socket or a named pipe. A more difficult but more efficient
way is to use shared memory for IPC. As I don't expect two clients to
connect simultaneously with the same user id, write conflicts will be few
(I suppose writes will be few too).

In our environment I have found FSSession to be very fast, probably
because the OS caches files. If someone complains about FSSession's speed
I will code the caching product.

On Zope, I created a new ZClass, EBook which is Subclassing, CatalogAware,

I created an instance of EBook which id is 'aid' in a Folder called 'new_test'.
It works fine in Zope except I cannot use my writeData method of my EBook
class because of the following error:

I work with Linux and all users have the right to write in /home/oscar/data'.
I even tried to run the method from the interpreter, just changin
f.write(self.data) to f.write('arbitrary string') and it works fine.

**Can you tell me where am I wrong?**

I also tried to use the debugger to understand where I am wrong.

Or even better, a generalized version - so you could serve perl and php and
python cgi  scripts transparently from zope.  That's be pretty cool actually
- migrating our old sites from php to Zope would be trivial.  

Of course, it'd be much slower than having PHP3 compiled in to Apache.

Subject: [Zope] ZEO app architecture options
Message-ID: <38DA5AD1.EE6A264B@texoma.net>

Hello,

In light of ZEO becoming open source, I'm still extremely excited, I
want to revisit some questions I threw out in a previous thread about
Zope's scalability.

Can I architect a website like this using different Zope Storage Servers
for the various directories or 'would be' tables in an RDBMS? Yes, I
understand the impact of the OS filesystem concerning ZODB size.

Say for example I have a large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5+gb directory which is reasonably
stable updated monthly.
ZAuto/manufacturers isn't as large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.


Also, when comments are made about Zope's ZODB or ZSS not being
appropriate for heavy write apps, does this refer to apps doing
"updates" on objects or doing "inserts" or both using SQL terminology?

Would structuring an app like above help in write situations?

I am trying to determine the desirability or necessity of an RDBMS for
my idea. I like keeping it in Zope if reasonable and ZEO can definitely
help. If need be I'll go to an RDBMS for certain data.

Thanks for any help or clues.

As much as I appreciate the desire to get at ZEO early, we have to
balance that with our limited resources internally.  We're taking a
conservative approach to getting it out the door, rather than just
dumping code and telling people they're on their own.

Hopefully everyone can appreciate this.  Unfortunately we're taking a
lot of flak, for instance, for not releasing Tracker.  I wish we had
unlimited resources, but that's just not the case.  As everyone in the
Zope community will probably agree, we need to do a better job and not a
bigger job.

This isn't necessarily true.  Zope caches objects, and the scenario you
describe is well suited to the caching strategy.  (That is, a user is
probably going to come back again within a minute of their previous
request.)

Compare this to an RDBMS strategy where state is always being retrieved
on each request.

The PTK membership model allows arbitrary extension of methods and
attributes.

Sorry, I forgot that I hadn't uploaded the text of the FAQ.  My network
connection was horrible yesterday (I'm in a hotel in the Bay Area right

You'll need to write some software in Python that will interface with
Zope for printing to your local Linux printer. In general, this isn't
something one would normally go about doing.

Now I just get "You don't have permission to access /Zope/home on this server." no login prompts start screens or anything.

Is there anyway of debugging the interaction between Zope and Apache rewrite?

Why not use something like SWIG (I don't know much about it, just a general
idea on what it does), to link the interpreter to python, and then make a
Zope extension like <dtml-perl xxx> to call it? Then you could probably get
the perl/PHP scripts into the ZODB, and therefore get cached, making it even
faster..

i think you need to set permissions to execute cgis within that
section, ie. put

Options ExecCGI

into your <VirtualHost></VirtualHost> section

Subject: [Zope] Troubles with SQL queries
Message-ID: <Pine.LNX.4.10.10003231313390.10023-100000@odeon.net>

Heya folks,

I've got an SQL query that looks like the following:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.date, gigs.start_time

This works fine.  The '/'s indicate that a single line continues, in the
ZSQL method the 'and gigs.date >= etc." part is on one line.

I'd link to be able to change the values the query is ordered by based on
the link used to access it.  Something like the following:

http://foo.bar.com/Zope/query?first=date&second=start_time

Towards that end I made the above look like:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.<dtml-sqlvar first type=string>, /
    gigs.<dtml-sqlvar second type=string>

When I test the ZSQL method it shows the SQL used as:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "2000/03/23"
  order by gigs.'date', gigs.'start_time'

Note the 'date' and 'start_time'...  Because of the 's the query does not
work.  

Is there a way to not have the <dtml-sqlvar> tag return the 's to MySQL,
or is there another way I should be trying to do this?

Thanks for the help,

Jeff Robertson

Subject: [Zope] How do I pass parms past a redirect?
Message-ID: <38DA80A9.411DFC15@sage.att.com>

i'm building an app that requires me to connect to another
server in the company to do employee authentication.
one connects to that site, passing a return URL.
it verifies the employee, sets a cookie, and redirects
to the URL you gave it.

so, in a document i want to protect, say, ChangePerson.dtml,
i've got something like:

<dtml-if "REQUEST.cookies.has_key( 'attESSec' )">

	...regular actions for the page...

	<dtml-call "RESPONSE.expireCookie( 'attESSec' )">
<dtml-else>
	Missing attESSec cookie!
	<dtml-call "RESPONSE.redirect(
'http://othersite/cgi-bin/authenticate?retURL=http://mysite:8080/ChangePerson&sysName=foo'
)">
</dtml-if>

note that the URL i redirect to expects two parameters,
retURL says where to return, and
sysName is an application name given when
i registered to use their services.

so far, so good.  the problem is, my document expects to be
called with some parameters passed, like:

	<a href=ChangePerson?hrid=1234567&name=garry>Change</a>

now, i can't encode these parameters in the retURL
i pass the other site, as i get a "malformed syntax" error.

so, my question is, how do i make this information available
to my script on the return?  do i set a variable in the container?
set a cookie?  or is there some better way?

to broaden a bit, how does one pass information around in general?
so far, i see several methods, for calling:

External Method: piece of cake.  real live arglists, like god intended.
DMTL Doc from form: form variables, mixing hidden vars in for other
stuff.
HTML links: cgi-style syntax, leads to ugly URLs.

is this the right way to do things, or am i missing something?

Subject: [Zope] xmlrpc authentication woes
Message-ID: <38DA8147.3E2F3325@boi.hp.com>

First, let me say I have patched my xmlrpclib.py to support
authentication; that isn't the problem.

Overview:
I have a folder, 'Administration', which requires manager login to
access. In this folder is a subfolder called 'MachineTracker'. In this
folder is a collection of ZSQl Methods, DTML Methods, and DTML
Documents. What I want to do is to connect to the server via XML-RPC,
and make use of the ZSQL Method for inserting data into the database.

Problem:
When attempting this from python in XML-RPC, I get a 401 Unauthorized
error. I can access the folder, and other methods, such as index_html()
and objectIds() with no authentication issues. 

Any ideas?

(please cc me here, this isn't my subscribed address)
TIA, Bill

 You can use one of the Session products (SQLSession or FSSession) to
store arbitrary per session info (even Zope objects) on the server. It is
probably the cleanest solution.

Use the handy dandy Python range operator (generates a list of ascending

<dtml-in "_.range(noOfTimes)">
  <input type="text" name="...

A simple question, how can I determine the Owner
of a ZClass instance (or any Zope object for that matter)?

My users create instances of a Seminar ZClass.  I did not
create a SubmittedBy property (which I would fill from
AUTHENTICATED_USER.getUserName()) thinking that I could
easily extract this from the Owner role.  I just can't
see how to do it.

I have run into this problem before.  Floating about on the ZOPE site is a
patch for the MIMETools, which addes a few *_expr attributes, so you can replace

name="_['file.filename']"

with:

name_expr="_['file.filename]"

I have just written my own tag product (may or may not be allowed to release..
we'll see :)  I understand now why this is so.  It seems that, so far as the
product is concerned, there is no real way to tell the difference between a
string and an expression.

If I am mistaken, I would dearly LOVE someone to point me in the right
direction.  I currently distinguish vars and strings by if they have 's around
them, and expressions are attrib_expr.

But I digress.... the patch is your friend.. It is on the ZOPE site (sorry I
can't be more specific, but a quick search will find it.)  I have used it
myself, and know it works.

Message-ID: <000f01bf9521$065bc480$2aac8ec6@hikari.anu.edu.au>

I have a container ZClass Person.  Person has a (string) property
CurrentPosition which gives the id of a ZClass instance contained
in Person.  Example:

   DarranEdmundson (Person)
       bsc_degree (Degree)
       phd_degree (Degree)
       fellow     (Academic)
       fujitsu    (employment)
       vizlab     (employment)

where DarranEdmundson.CurrentPosition = "vizlab"


I am having problems accessing the CurrentPosition object
in a pythonMethod.

list = []
for person in self.objectValues('Person'):
     position = _.getitem(person.CurrentPosition)
     list.append(person.LastName, position.anyProperty))


I can do it in DTML via

<dtml-in "objectValues('Person')">
<dtml-with "_.getitem(CurrentPosition)">
   <dtml-var LastName> <dtml-var anyProperty>
</dtml-with>
</dtml-in>

I think the question really comes down to: how does one
achieve <dtml-with name> in a pythonMethod?

Darran.

Subject: [Zope] how to get the fields returned SQL method
Message-ID: <86ln39meyg.fsf@marcelle.revolink.com>

Hello,

I'm trying to get a list of fields returned by a dynamic SQL query.
I've found a howto telling me to write something like :
	<dtml-in SQL.names>
	<dtml-var sequence-item>
	</dtml-in>
But it doesn't work : I get the error "Attribute Error : names".
I've tried with .items, .keys and .fields too.

I'd like to do the same for an LDAP query.


Any idea ? I think it's very useful and that an easy way exists but I
can't find it.


Thanks,

EB.

OK, so I read the Advanced Catalog Search HowTo, and I am left with
a couple of questions.  I'm concerned here with "or"ing the searches
on two fields.  The first question is, once I do the OR is the
result (which may be close to a thousand records) cached?  Otherwise
I don't think this is going to work.  Even if it is cached, I'm
thinking it may not work.  Is there any way to do an OR without
loading both result sets into memory?

The other question is, when I do the OR, how do I reduce the
composed list to just unique records?  The HowTo seems to just
do a sequence join, which would leave me with duplicated records
for those items that matched on both search columns.

Well, since the SQL will return a list, firsly you would have to index it...
also, .keys et al are Python stuff, so...(untested)

<dtml-in "SQL[0].keys()">

might be more what you're looking for.  Or...

<dtml-in SQL>
  <dtml-in "keys()">
    <dtml-var sequence-item>
  </dtml-in>
</dtml-in>


should iterate through the keys of each line of the returned table.

ZEO is transparent to the application, it is a _singular storage_
meaning that all the issues of multiple databases still apply, re, they
are not yet supported.

What this needs is the ZDBF (Zope DataBase Framework).  This is a layer
that sits above ZODB.  Currently, ZODB takes care of all these issues
(or punts on them) when really a higher level abstraction should handle
multiple database issues (including any future extensions to the
Relational/Object model).  Obviously, this is a big task.  See paul's
email about resources. ;)

First, keep in mind that to a certain degree, all databases are
sensitive to the high-write issue.  ZODB is more sensitive because it's
conflict resolution is optimisitic.  FileStorage is also sensitive
because of the  inherent behavior of filesystems, and ZEO is sensitive
because for every object written, an invalidation message must be sent
to all other ZEOs so that they are given the chance to invalidate the
object in their cache.  This also increases chances of collisions
because the Time To Write a record is extended for varous reasons
(network delay, invalidation delay, etc...).
 
> Would structuring an app like above help in write situations?

Not without ZDBF.  Multiple database support would allow you to use
different, less write sensitive storages like a RelationalStorage or a
BerkeleyStorage.

Do some benchmarks, ZODB is very fast if you are a little more clever
about how you change your objects.  If you need more write intensiveness
go relational.

One doesn't.  Instead one uses local variables, as you did with 'person'.
Your solution is almost complete, actually, and should work if you replace
'_.getitem(person.CurrentPosition)' with one of the following (I'm not sure
which, you'll need to experiment):

person[person.CurrentPosition]
getattr(person, person.CurrentPosition)
person.aq_acquire(person.CurrentPostion)

Sorry I can't be more specific.  In general, though, any place you would use
dtml-with in DTML, you set up a local variable in PythonMethods.

Cheers,

Evan @ 4-am & digicool

Message-ID: <200003240350.AA11082@rsphy9.anu.edu.au>

I recently took the site I have been developing online
and have been beta testing with several users.  I
have a problem which is preventing a user from
viewing his home page; any attempt I make to isolate
the problem hangs Zope, stops anyone accessing
my site, and requires a forced unix kill.

The user's page is:
   http://rsphysse.anu.edu.au/optics/people/jdl124

Users are implemented as a Person ZClass.  One
of their contained objects is a PublicationFolder
ZClass, itself a container class for Journal ZClass
instances.  So above:

optics (folder)
   people (folder)
      jdl124 (Person)
         publications (PublicationFolder)
             article1 (Journal)
             article2 (Journal)
                .
                .
             article69 (Journal)


jdl124's home page is dying when it tries to iterate
over the results from a search of the ZCatalog publicationCatalog.

The problem isn't in the publicationCatalog however, the following DTML snippet locks up my Zope completely:

<dtml-with jdl124>
<dtml-with publications>
<dtml-in "objectValues()">
    <dtml-var id><br>
</dtml-in>
</dtml-with>
</dtml-with>

I can deal with this during solo testing but my users' budding confidence in the system I have created
has been mildly rocked by this situation.  Needless to say, jdl124 is none too impressed.  Any help
you can offer is most appreciated.

Cheers,
Darran.

This is a bit odd.  I have some image objects that display fine in
IE 4, but in Netscape 4 I get a Zope error

Invalid Date-Time String
Tuesday, 29-Feb-00 17:53:59

The traceback ends with DateTime.py, line 848, in _parse.

Is this a Y2K-leap error, or is something else going on here?  I've
checked two of these images and in both cases the date it is
complaining about is on the 29th.

And why only Netscape 4 and not IE?

I think you want this, which (it claims) generates PDF documents within
zope.

http://yyy.zope.org/Members/gaaros/ZpdfDocument

Then you just print it however your clients are already printing.

--------------11C1869DF092DB44C388B170
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

Assuming you are just going to be using linux this shouldn't be _too_ hard.

You probably would want to firstly use the http client module in python
(not sure exactly what it is sorry). Which could download a html page which
is generated by Zope.

The with the html page you can make a system call to "html2ps temphtmlfile temppsfile;  lpr temppsfile -Pprinter". Python has the ability to simply call 
external program (i think it is os.system( ) ). Of course you could find/write
your own html->ps and printing code but when you already have html2ps and lpr
I wouldn't really bother.

Now if you wrap all that up into an external method which is called when the 
print button is pressed it should be quite acceptable.

Is this the type of thing you want or am I off in another planet?

Why not generate a PDF file on the local file system and then print it

just my 2 cents...

I think a translator should implemented using a flag in dtml-var:

syntax: <dtml-var VARIABLE translate> and <dtml-var VARIABLE 
translate="de"> for example.
Short form: &dtml.translate-VARIABLE;

By default it chooses the root folder's (or even Zope's?) language setting, 
but the programmer can also choose the language. This syntax is very 
similar to the "missing" flag. This way you do not a separate phrasebook 
and word translator. All that is in the background....

Then there is a generic translate product which handles all the translation 
stuff and administrates the languages. One can easily drop languages into 
the product, by installing simply the dictionary for this language into 
some standard location and specifying some admin info.
I think that would be the cleanest way to implement ZIP.

What do you guys think? Comments?

Stephan

I tried sticking <dtml-var get_local_roles> in a dtml document and got a blank list back even though
I know I've got some local roles.

Also, where did you find out about this? I haven't found it documented anywhere...

<dtml-var "AUTHENTICATED_USER.getRoles()"> is also not too useful since it only returns roles where
the user object is defined, ie no local roles...

What am I doing wrong?

References: <86ln39meyg.fsf@marcelle.revolink.com>

Okay, a lot depends on what your query is returning.

If 'names' is not the name of a column, then ignore the rest of this message ;-)

If it is, then try the following:
<dtml-in SQL>
 <dtml-var names><BR>
</dtml-in>

- If 'SQL' returns a single row and 'names' is a single-valued column, then it should display the
value of names.
- If 'SQL' returns multiple rows and 'names' is a single-valued column, then it should display the
value of names for each row returned on a seperate line.
- If names is a multi-valued column then you should get something like
  [...,...,...]
  for each row returned.

cheers,

Chris 


If names is a single-valued column then the following should work

I experienced this as well also on Netscape (but I didn't try with IE)

Did you create the images on Feb 29th? I think I did and made the problem go away by re-uploading
the images.

This is a bit of a worry though, anyone got any ideas what's going on?

Hi Chris

I wrote Amos for exactly the same thing and here is his answer:

...
This is a Zope error. I was working with a development version of Zope
which didn't have the error. The error is fixed in CVS and should ship
in the next release of Zope. To fix the error add this line near the top
of your lib/python/Products/ZCatalog/ZCatalog.py file.

from DocumentTemplate.DT_Util import Eval, expr_globals

Hmm, are you sure you're not trying to include python methods rather than DTML documents or DTML
methods?

Try:
<dtml-var "id()"> if there's not another reason why this isn't working...

Provided that ID contains a string representation of the id of the
document you want, this should do it:

<dtml-var "_[id]">

I hope I understood what you wanted to do, this may very well be
solving the wrong problem.

Hmm. That's not what happens for me. I get something like:

[('admin', ['Owner'])]

How do you know you've got some local roles? Also, is this a DTML document or
DTML method, because methods seem to acquire the roles from their container.

> Also, where did you find out about this? I haven't found it documented
anywhere...

It's all in AccessControl/Role.py.

IMO the documentation is just a good place to figure out where to start reading
the code. ;)

Is there any simple way to do this kind of things in

Subject: [Zope] error with ptk
Message-ID: <028801bf9584$2e178be0$722624d5@amazigh1>

I began to download and to install PTK's last version recently. I installed
the product by following procedure described in the file " Read Me ", and I
so obtained three new elements in the section products. But when I try to
create a new element "Portal", Zope sends back me an error. I search so the
details of the installed products and I notice that in the part " DemoPortal
" certain elements are broken:

It is a question of:
 . " DemoPortal / Portal "
 . " DemoPortal / PortalWizard "
 . " DemoPortal / Wizard "

In fact they are all the DemoPortal's ZClass which are lacking. Can it
involve a conflict with another product? Is it necessary to settle PTK on
Zope's clean version?

I work with:
Zope version: Zope 2.1.2 (binary release, python 1.5.2 , win32-x86) on Win
NT4 / sp4, as well as with Zope 2.1.4 on Linux Mandrake 7.0. (on whom I did
not test PTK because it is my working environment, and I do not wish to
pollute it).

Thank you for advices. I intervene only rarely. What is well , it is that
major subjects and basic questions were approached in depth, repeatedly,
what allows to avoid resting the same questions. By getting back this
information, the people of the ZDP make a formidable job. That has the taste
of object oriented thinking...

PS: In reality, the best way to learn Zope (IMHO) is to start with the guides
and then read the mailing list religiously.

The guides are at:

good luck, it is worth the effort ;-)

It doesn't work too. I can't understand why.
More general, I'd like to extract all the variables available in a
namespace (and if I can do it, I'll can get the list of the fields).

Hi,

I'd like to add, modify and delete entry in an LDAP directory. I've
quickly read ZLDAPConnection's source and I guess that fonctions
"_addEntry", "_deleteEntry" and "_modifyEntry" can do what I'm looking
for, but I can't imagine how ! :)
I've tried a LDAPlink.addEntry('dn','values') in a dtml-call. Apparently
it work, but there nothing new in the directory :(
Have you any ideas ?


Thanks,

Same suggestion. How it works (one possible way of doing it):

Using a standard Linux installation, create a document with your data in a
Python method and safe it as a local (temporary) file (e.g. using the PDF tools
that exist for Python, e.g. "PIDDLE"). Then just do the following in your Python
code:

import os
os.system('lpr /path/filename')

This works under Windows, too. Just replace the system call by something
appropriate like "copy path\filename lp1".

It should also be possible to redirect the stdout data stream directly to the
printing device. 

I have also found some more sophisticated solutions:

- using the classes wxPrinter and wxPrintout from the wxPython package
- for Windows: using the Printer API directly with
   import win32ui
   import win32com
   ... (gets complicated)

Hi,

Sorry, there are no book of Zope, yet. Many (I think) are comming.
You can also have a look at ZDP : zdp.zope.org

Hi All!

Now and then there are strange things going on with my Zope 2.1.4/Linux
Intel installation.
Ok, here is what happens:

http://www.myhost.de:8080

raises a Zope Error (Attribute Error, getUserObject)

http://www.myhost.de:8080/manage

requests authentication and I give as UID/pwd as the superuser's pwd.
Again, strange Error-Messages.

I repeat (non-deterministic number of times) this and suddenly: everything
is ok.

What can this be??

Regards, Ingo.

Eddie,

I seems from your traceback that the user you are using to
_run_ your Zope process does not have permission to read 
some (or all) of the Zope files from the filesystem:

> IOError: [Errno 13] Permission denied: 
> '/usr/local/bin/Zope-2.1.6-linux2-x86/lib/python/App/manage.dtml'

You need to make sure that either you run Zope as the same 
user you used to install it, or change the filesystem permissions 
so that the user you are using has read access to all of the 
Zope files (and write access to the /var directory and any files
in the /var directory).

Hope this helps!

Authentication is not your problem, the user your Zope is running as
does not have permission to read it's own files.  Keep in mind that if
you run Zope as root, Zope will automatically demote itself to the user
'nobody', this is a standard practice of many servers as running a
server as root can be a security hazard.  If you want to run Zope this
way, then make sure that 'nobody' can at least read everything, and can
write to the /var directory.  

Otherwise, run Zope as a user that can read its files.

So do I.  Several people have reported this bug, but I cannot reproduce
it.  No one has been able to reproduce it or tell me how to reproduce
it, therefore, I cannot fix it.  The only thing I can tell you is that
it has to do with ZClasses that catalog themselves and that it happens
rarely and that updating your catalog allways fixes it.  I suspect it
has to do with poorly engineered ZClasses.

The method that contains this code.  You are probably experiencing some

Message-ID: <00032409234800.00783@modemcable215.47-200-24.mtl.mc.videotron.net>

HI,

How to get information about a ZClass property sheet from outdside the ZClass?

The goal is to create a "myzclass_addForm" that generate automatically the
input fields for the ZClass propertysheets.

In tried this:
/Control_Panel/Products/MyProduct
	myzclass
	myzclass_addForm
	myzclass_addPermission
	myzclass_factory

I just modified "myzclass_addForm" to add:

<dtml-in "ebook.propertysheets.common.mypropertysheet.propertyMap()">

...stuff to generate the input for each property.... 

</dtml-in>

It worked fine when I called "myclass_addForm" by clicking on the "View" tab of
the myzclass_addForm management screen. However if I try to add a MyZClass
instance from anywhere in my Zope hierarchy, I get the following message:
"Authorization failed. Retry?" and if I cancel:

"Unauthorized

       You are not authorized to access common."

I tried to change permissions and proxy of my myzclass_addFrom but it doesn't
work.

Can someone be sweet enough to tell me where I could find docs on how to access
the propertysheets elements.

Thanks

Hopefully it will be up on /. today. Hope the Zope.org servers are ready.

There is also a Zope Discussion Board at DevShed (based on UBB) which is
pretty quiet now. It might be a place to get people learning about Zope who

Hi,

if you want to hide them based on permissions, this is easy. Set the "Access
content property" to the correct value and it works. This is the way I do it
for my application, where I have browseable admin area and a public area. If
    an admin logs in, he sees the admin area too.

If this is not the case, then do a 

<dtml-tree>
    <dtml-if "id=='x'">
        display as you like it
    </dtml-if>
</dtml-tree>

Bye, Oliver

I didn't create the images, but I would not surprised if they were
created then as there was a big push to get things uploaded before
the 1st.

I can have them reupload the images to work around the problem, but I
agree that it would be much better to know what the bug is.

I've implemented a variant of Michel's suggestion. Let me explain what I
am trying to do. I'm trying to implement the
SelfServeFAQ:www.lcg.org/ssfaq (SSF),written in php3, within my Zope
website. To give a consistent look to my site, I also want to wrap the
SSF with standard_html_header, etc. So when a visitor goes to
www.mysite.com/FAQ they are really being served
/SSF/directory/index.php3 wrapped with my Zope code.

The problems come when a user clicks on www.mysite.com/FAQ/add.php3 or
some such similar link in the HTML produced by index.php3. I tried using
mod_rewrite in Apache, but found that Zope used
www.mysite.com/FAQ/add.php3 as the base for all the links in the
wrapping code. The only way I found to avoid this was to use the "[R]"
flag in the Apache RewriteRule. 

But I want SSF to be transparent to the user so instead I used
SiteAccess to rewrite /FAQ/add.php3 to /FAQ and pass /FAQ/index_html the
script name "add.php3". index_html then uses lstaffor's How-To tip( use
"Client.call( www.mysite.com/SSF/directory/add.php3)[ 1 ]" ) to embed
the PHP script call in my Zope page. In addition, I wrote additional
code in my accessRule to pass images in the PHP directory tree via Zope.

There is one inconveniences with this approach: I had to hack SSF to
remove the <html> tags and some others returned by Client.call (it
worked otherwise but, hey, I want my HTML code to be clean). But all in
all, the resources of Zope (the code and the community around it)
allowed me to solve the problem with very little modification of the SSF
PHP directory tree contents.

If there is wider interest on this I could write a How-To on it.

Michel, I take back the assertion in my private email.

I've just determined that this glitch in my
CatalogAware Journal ZClass (using a custom catalog
as per http://www.zope.org/Members/AlexR/CatalogAware)
arises whenever a user edits an instance of this class.  

Users are using the standard Zope management interface 
but I have substituted the standard Properties View 
with an "Edit Journal" View.  This is a copy of the 
Journal_AddForm method (with default values culled from 
the now existing instance).

As per #4 in the above How-To, on submission this calls 
the following DTML method which puts my publicationCatalog 
in a strange state (requiring the update):

<html><body>

<dtml-call "propertysheets.Properties.manage_changeProperties(REQUEST)">
<dtml-call reindex_object>
<p>Changes saved.</p>

</body></html>

I desperately need to sort this out before users start
making changes.  I certainly can't do an update of
the catalog on every edit of an existing Journal
instance.

Any help is much appreciated.

Cheers,
Darran.

Hello,

I intend to get from fatbrain the e-matter edition of the Learning Python

The problem is that they mention that e-matter works only on windows
platforms, and I want to know if it is possible to print the book so that
I can use it while working my computer, which does not run windows.

Thanks in advance.

What would constitute a poorly engineered ZClass?  I've seen this
problem with a ZClass that is descended from just CatalogAware,
has a few properties, and for which I've rewritten the Add and Edit
methods to call reindex_object.  I'm not sure how I could engineer
this simple class better, but I don't really understand why I have
to rewrite the Add and Edit methods to call reindex_object,
so it could well be that there are improvements that could be made.

In my case, I did not even do an update catalog.  After adding
a few additional objects, the error message went away on its
own.  (I didn't do a catalog update, because if I do that the
meta data for the id field gets completely screwed up, so I stay
well away from catalog update).

I am running under SiteAccess, and I have a sneaking suspicion my
problems orignate there.  I'll be moving the database to a
dedicated server soon and will remove SiteAccess.  If I see the
error again at that point I'll let you know.

Imagine I have a python extension, with zope id pyFetch

I want to call this in a manner similar to:

  <!--#let call_method="'pyFetch'"-->
    <!--#in sql-method-returns-href-->
      <!--#var "_[call_method]( href )"-->
    <!--#/in-->
  <!--#/let-->

But I get an error:

  Error Type: TypeError

So it seems to evaluate and call the extension without adding the
parameters.  I guess I need something like lambda in python.

Can anyone help me please?

Subject: [Zope] Newbie question: using backing files.
Message-ID: <013c01bf95b2$9320f070$afe9612f@entrust.com>

I have a situation where there are some HTML files which I do not control
that I would like to open up to access through my Zope server.  I don't want
to import these HTML files as Zope objects because these files will
frequently be edited and updated in place and I want any changes made to
these HTML sources to be immediately reflected in Zope as they occur.  I
also don't want to just use a URL to access them because a) the end-users
shouldn't be aware that they're exiting Zope scope for these items and b) no
URL could possibly point to these files since they're actually stored in a
revision control system through a "view" (in essence, a virtual local
directory tree).

So what this basically boils down to is this: I'd like to take a URL like
this...

    http://my.intranet.site/Documentation/ComponentSpecs/MyComponent.html

...and have the logic behind it conform roughly to the following pseudocode:

    1. Switch to "/viewdir/source/component/MyComponent/doc".
    2. Open the file "ComponentSpec.html".
    3. Serve up the contents of that file to the user.

The user should see no visible signs that the data comes from outside of the
Zope environment.

I've already investigated using an external method to accomplish some of
this.  For example I served up an outside file in almost exactly the way I
wanted to accomplish this using code like the following:

    def testMethod():
        s = ""
        f = open("/viewdir/[...]/ComponentSpec.html", "r")
        for l in f.readlines():
            s = s + l[:-1]
        return s

Indeed this does EXACTLY what I want.  (In any production version of
this--this was only a quick'n'dirty hack--I'd be doing some significant
caching and version checking.  But the example gets the drift across.)  The
only problem is that I can't figure out how to translate a URL like the one
I provided above into a method call like testMethod("MyComponent").  (The
documentation on these things is a bit... spare.)

So does anybody out there have any suggestions?  I'm not afraid to get my
hands dirty with Python (it being my scripting language of choice for the
past 4+ years) and I'm not afraid to learn Stupid DTML Tricks.  I just don't
know enough Zope yet to even be dangerous.

Subject: Re: [Zope] Printing from Zope.....Report writer building


I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

I haven't bought the eMatter edition of Learning Python =), but I did by the
Eff-bot's guide.  I was able to print it fine, although personally I prefer
nicely bound books to large amounts of single-sided A4/letter pages with too
much whitespace around the borders.

Also, know that some folks have had problems with eMatter's distribution
schemes, especially those with non-US installations of Windows, from what I
gather.  Luckily, I hear that fatbrain's technical support helps folks get
past these issues.

On the positive side, I do like the ability to search PDF files.

the 'address' mentioned there is the port (one of the ports) zope is
listening on. this means either you already have some process (zope?)
listening there or your os thinks that there is some process on this
port. 

in the former case look if there's one of your zope processes still
there (e.g. 'ps auxw | grep python' to list your python processes (on
linux)) or if there's some other process using it ('socklist' will
tell you if its in use); in the latter wait a little, the os will
usually grok this eventually.

We have very erratic crashes, the only commonality we can find is
volume.  When requests are low the system is awesome, but once load
starts increasing we see frequent restarts, once an hour at least.  This
could be due to people experience slower response times and breaking the
connection to attempt a reload.  From what someother people have been
saying a 'broken pipe' error in zope_msg.log may cause all the threads
to die off.  The problem here is I generated 30-40 'broken pipe' errors
and could not crash Zope.

When you run ab against it are you hitting a wide variety of objects or
the same page over and over.  I've had Zope perform great accessing the
same page repeatedly but show some strain once you vary it's diet a bit
especially when cached SQL results are involved.

What server method are you using on the sandboxes.  We use a combination
of ZServer and FastCGI connections for our traffic, with all /manage
going through FastCGI and the actual public traffic using a mix of
FastCGI & ZServer.

I can't get this to work.  When I try it all the messages come on the
screen like they should, each service that is up etc, but the darn thing
will not answer requests.  As soon as I run the exact same command w/o
strace it works.  I've also tried to attach strace directly to the
already running processes, and no luck.

As soon as I'm able to collect more info I'll forward it to you.  Is
there anywhere else I should be posting this information?

Please send any new info to all of us. I could not get strace to work
either but what is puzzling, I will get the problem even on a no load
site.

Hi,

As I didn't receive any answer from my previous message, I guess it wasn't very
clear.

How can I get a list of property.ids, property.types of a ZClass propertysheet
from outside the product containing my ZClass.

I tried a lot of things but i hit a wall.

Thanks

This should be easy, if you can get Zope read access to the files...

Use Jonothan Farr's Local File System Product.

I don't know what you mean by "python extension" -- is this an ExternalMethod? 
A PythonMethod (it doesn't look like one)?  A method of a class defined in a
Python product (I don't see an instance anywhere)?  I'll assume an
ExternalMethod, because it looks most like your stuff.

Assuming you have a folder, which contains/acquires an ExternalMethod,
'pyFetch', defined as taking two parameters, as above (I'm assuming from your
description that you have the EM with a different ID than its underlying
function -- that works, but for clarity I would generally avoid that).  This
folder contains/acquires some method, 'list_hrefs', which returns a list of
objects which have an attribute, href.

In a DTML method contained/acquired by that folder::

  # I'm using a PythonMethod which returns a list of dicts,
  #  so I am using the 'mapping' argument to get its key/values to
  #  look like attributes.

  <ul>
  <dtml-in list_hrefs mapping> 
    <li><dtml-var "this().pyFetch( href )"></li>
  </dtml-in>
  </ul>

That works for me -- I get an unordered list of the results of calling pyFetch()
on each href "attribute".

Message-ID: <01b401bf95da$0c434e90$29a8efd0@atinucleus.com>

I use an external python function to return the SQL result set.

here it is: ( I reference it as an external method called getRes in Zope)
---------------------------------------
def doPySQL(self, zQry) :
    tvar1 = 'res=self.'+zQry
    exec tvar1
    return res._schema.items()
----------------------------------------

This function returns a set of key/value pairs that are the column_name/column number

Here is the dtml document I used for testing: (UserSettings returns info for a user)

-------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=getRes('Your_Query_Name_Here()'))">
<dtml-var "_.len(t1)"> Columns<br>
<dtml-var "_.str(t1)" html_quote><br><br>
<dtml-in t1>
<dtml-var "_.str(_['sequence-key'])"> = <dtml-var "_.str(_['sequence-item'])"><br>
</dtml-in>
<br><br>
</dtml-with>
</body></html>
______________________________

This code will give you a listing of column names and values
sorted by column name for every record returned by the SQL Query:

--------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=Your_Query_Name_Here(),t2=getRes('Your_Query_Name_Here()'))">
<hr>
<dtml-in t1>
  <dtml-in t2 sort=sequence-item>
    <dtml-var "_['sequence-key']"> = <dtml-var "_.getitem(_['sequence-key'])" html_quote><br>

Look at how Zope's management interface does it
($ZOPE_HOME/lib/python/OFS/properties.dtml).

to Garden Gnomes, is there some way that I could index every site listed in

You allready have a service that is running on a port Zope wants.

Zope wants 8080 (for web) 8021 (for FTP) and 8099 (for the monitor).

It's just a suspicion, and as I noted in my previous mail I cant tell
you constitutes a poorly engineered ZClass because I can't reproduce the
bug.  By 'poorly engineered' I mean both the possibility that the bug is
manifest of the user createing the ZClass, _or_ that the ZClass
implementation is broken.  I did not mean to point fingers.

Can you reproduce it deterministicly?

Because when you change an object, you must inform the catalog that the
object has change so it can update its indexes.

This is because one of your new objects filled in the missing hole, it
may have made the problem go away, but it didn't fix it.

This has never happened to me, can you reproduce this deterministicly

What I need to fix this is a way to reproduce it.  If you can do this,
then I need your help.  I would like to see your product, but first I
have to make sure that I *can* debug this using your product.  Your
produce needs to be self contained (not dependent on subclassing python
code I don't have) and must not use any relational database stuff as I
cannot reproduce your database environment.  In other words, if you can
drop your product into a clean Zope out of the box and reproduce this
problem, then you _are_ then man.

i had the ned for this too at the start of my current project.  I
actually have the fortune of having a smart printer.  If I shoot a pdf
via lpr, it just prints it.  It's an HP 4050.  

lpr -P HP4050_raw myfile.pdf works fine.  So I was just writing an
external method to slap that document to my printer.  But I stopped
thinking  about this because we decided online delivery of all documents
was okay and other things took priority.  

If you wanted to print more than just plain text, I guess the mime type
would have to have a "printer" application sort of, or filter just like
they have "viewers".

Has 'weighted' banners.
If you have 2 banners, each with the nromal weight of 1, each will
appear roughly 50% . If you assign a wieght of 2 to one of them, it will
appear roughly 67% of the time.

Our users were having problems accessing our site today. On examining the login

and everything was back to normal again.
Any ideas why these variable values were the same across multiple browser

Yes.  It lives in the zope extensions directory though - blame lack of sleep.

Problem: In real life, I don't know that I'm calling pyFetch, it could be 
pyDontFetch or pyGoToSleep etc (the "#let call_method" is in another DTML 
method and there are a few alternatives).  All I know is that it shares 
the same signature.  Works fine if you call it directly.

Is there a better method than the equivalent of

  <!--#if "call_method=='pyFetch'"-->
    <!--#var pyFetch( href )-->
  <!--#elif "call_method=='pyDontFetch'"-->
    <!--#var pyDontFetch( href )-->
  ...


Thanks

index_html is a 'DTML Document' and other documents are actually 'DTML

Message-ID: <38DC4561.AB3F9A72@imeme.net>

Zopistas,

how do I pull this off?

<dtml-in "objectValues(['Folder'])">
  <dtml-with sequence-item only>
   <dtml-unless noshow>
    do something
   </dtml-unless>
  </dtml-with>
</dtml-in>

I've tried messing around with the _ variable, with little luck.

This is part of a menu, and the thing is, even if I don't want to show
the folder in the menu, I don't want the menu to disappear when I'm in
the folder.

thanks,

Ethan Fremen

Hi everyone,

I'm hoping that someone on the list has some experience with NetWare's NDS.
The school district where I work is a NetWare shop with the exception of
the Web server which is running Linux. A couple of my students and I do the
Web stuff on the side.

Starting in the fall, I'd like to begin using the PTK and authenticating
users against our NDS directory. I'm wondering if anyone can tell me whether
Novell's recent release of their eDirectory product for Linux will affect
how we approach this. Are the existing LDAP Zope products sufficient?

Looking for some NDS Zen,
Tim

Some good news at last ...

When I set DEBUG in asyncore.py to 1 so I could view the lists going into
select, ZServer stabilised and hasn't crashed since. Smells like a race
condition and somehow the extra time it takes to print the list contents
stabilises things.

Still I cannot understand how the child process causes the supevising
(zdaemon) process to die too.

If your printer is setup is fine you can write the zope output to a file and
print it  using an external method 
If you can name your printale docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
pos = find(self.__name__, ".prt")
if pos >= 0:
redt = PrintJob(r)
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better
bet

This might be a seperate problem than The Mysterious Segment Violation. 
Can race conditions cause SEG faults? , I guess they can like any other
piece of code.  but I would expect a race condition to just spin the
process.  Can someone who I've spoken with about their SIGSEV problem
reproduce Pavlos' cure?

This makes me think it's a different problem also.  I get the feeling
you should be able to reproduce this problem on a fresh checkout on your
platform since it's so low level.  Can you check that?

The reason depends on how it didn't work.  Did it give you an error and

Interbase has gone open source, and the 6.0 beta version ( Windows,

www.interbase.com.

Looking at the contributed downloads, they have a Perl DBD driver, an
AOLServer database driver for Linux, and a port of the ArsDigita
Community System.

Pity there is no Zope support except from ODBC in Win32 - and that is
extremely unstable in my experience.

Hello Darran,


I created a new CatalogAware ZClass in Zope 2.1.6 with a custom Catalog 
name based on the information in the Howto.

It works fine so far. I didn't have any similar error when I updated the 
ZClass properties a couple of times.

If you can trap this elusive ZODB error please let me know. I'll update the 
howto if it's related.


Cheers.

Hello,
I have created a Zclass to publish FDF data for Adobe forms that can be used to
fill forms from zope (i.e create forms over the web). How can i get it added to
the contributed list ?. Is there a reveiw process to undergo ?

Hi, I'm hoping to get some feedback to a question I've had about whether
making ZClasses Catalog Aware is a good idea or not. Below is a my question
I asked and a few ideas from a response I received, can anyone
validate/invalidate any of these statements?

kh

Question:
------------------
Is it good practice to simply make ZClasses Catalog Aware by default, or is
this something that should only be done when necessary?

Response
----------------

 - Object cutting and pasting does not work properly for CatalogAware
 ZClasses. Is this a problem for you? Note you can still copy, paste and
 then delete the original object.

 - CatalogAware ZClasses look slightly more "fragile". I've seen posting
 about (fairly elusive) errors in Catalogs with such ZClasses. Note I never
 experienced them firsthand.

 - You could first create a base ZClass, then subclass it when creating your
 actual ZClasses. This base ZClass could include common stuff such as
 CatalogAwareness. Then if you change your mind you just need to modify the
 base ZClass. There is a way to change the base classes for a ZClass, though
 it's a hack.

Get a user name at the Zope site. Publish your product there. Someone at DC 
will approve it, and it will be on the official list.

Pretty easy. :)

How do you do that? That is my problem. Sometimes I forget a base class 
other times I have too many. Can someone write a How-to?

Subject: [Zope] Some basic questions concerning ZClasses
Message-ID: <00032518334200.08192@promotor>

I've just started to work with ZClasses. They are really cool. But I am running
into some problems:

I added a folder to my ZClass. Let's say the folder contains images. Using the
images from the folder in my ZClass methods works fine. But like all other
ZClass "internals" (methods etc.) the folder (correctly speaking: its
instance; or is there no seperate instance of the folder???) is invisible to the
management interface.

Is it possible to make a folder visible in the management interface so that
a user can enter additional images? Same with dtml methods/documents ...


Is it true that the methods of a ZClass don't open a new property namespace for
each instance? If I change the property of a method in one instance it seems to
be globally changed.

How can this be solved?


Thanks in advance

Joachim.

Message-ID: <Pine.SUN.3.96.1000325132704.16062A-100000@grendel.csc.smith.edu>

Hi all--- 

I'm trying to modify my copy of the SimpleURL product, and I need some
help. SimpleURL defines a property Sections within URLDirectory, where
each line is a section within a URL list. I've added another property to
my URLDirectory--- SectionDescriptions. I want to generate a list like
this:

SectionName1 (link)
  SectionDescription1
SectionName2 (link)
  SectionDescription2

I have the following code in the index_html of a URLDirectory instance:

<dtml-in Sections>
	<dtml-let  section=sequence-item>
          <A HREF="section_list?ts=<dtml-var 
"_['sequence-index']">"><dtml-var
section></A> <br>
	</dtml-let>
</dtml-in>


Now I know there has to be a way to modify that so that I can display the 
sequence-indexth element of the SectionDescriptions sequence. What am I
missing here?


And a design question: my URLDirectory is already fairly large; I may want
to create folders within it for each section. How would I adjust the
method above so that it looks to subfolder properties to display the same
information?

While I still have the training wheels on, I've been trying to be careful 
to understand the difference between DTML Methods and DTML Documents. I 
thought I was doing OK until I noticed this about the management interface 
(when looking at a folder):

There is a tab for Properties but none for Methods
The tab for Contents contains Methods as well as Objects

So either I don't really understand DTML Methods vs Documents, or the 
management interface should, to be consistent, also have a Methods tab 
instead of lumping methods under Contents. I'm not complaining, just trying 
to figure out the tricks so I can take the training wheels off.

Hi,

after I settled my problems with the Zope authentification system and

How can I allow a certain role to add local roles to an object? Which

solved the problem with a Manager proxy role, but I like to live without proxy

I have kind of a stupid question about sockets.  When starting zope (using

Note that what you're describing isn't really part of ZEO, it's really
more in the realm of what is already in Zope.  Thus, if you're eager to
add such a feature, you already have what you need.  Start tinkering
with the transaction machinery and see how you can extend it.

You asked one of the most tricky questions for beginners. If you look in 
the mailing list archives you will find the answer, but here my attempt:

I think of DTML Methods as functions that work on the folder they are in. 
Think about it this way: A folder is a class, then all DTML Methods are 
methods of the class Folder. They contain no properties other than id and 
title.
DTML Documents are on the other hand classes as well. So a DTML Document in 
Folder is like a subclass of the class Folder. Since DTML Document is a 
class, it can contain properties, while DTML Method does not.

Also, if you say: <dtml-var title> the DTML Method will return the title of 
the folder, whereby DTML Document will return its own title. That makes 
perfectly sense knowing the above definition.

How do I use them? Whenever DTML is called directly from the browser (like 
a link, or typed in  URL) I use DTML Documents. Whenever a document or 
other object calls DTML from inside I use DTML Methods.

I hope I did not confuse you. Don't take it as a major drawback to not 
completely understand the differences. It took me well over a month.

Regards,
Stephan

you can write the zope output to a file and
print it  using an external method 
not the cleanest way but works :
If you can name your printable docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
----snip snip --------
pos = find(self.__name__, ".prt")
if pos >= 0:
 PrintJob(r)
--snip snip----------
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better.
Another idea that I have tried :
inherit from DTMLDocument and create a new object type that will send itself to
the printer at the end of processing
 embed latex with dtml  and send the results to the printer using pdflatex.
There are some cool tex macros called context written by hans hagen that 
  can be used to create rich documents

How did you save the version? Did you click on the first button you see when
you bring up the Versin object in the management interface, or did you
actively go to the Save/Discard tab, where you can enter a message and then
save or discard the change?

To make a Folder show up in the ZClass instance, you should create it from
the ZClass_add method. For example, if your ZClass is called Foo, in the
method Foo_add, you could put a line:

<dtml-call "manage_addFolder('MyFolder')">

Then, every instance will have a folder called MyFolder in it.

Same thing applies for DTML methods/documents. Check out KM|Net News if you
want to see one way to provide default documents that the user can change.
KMNN also provides a way for the user to revert to the default.

Your properties should be stored on ZClass propertysheets. Then the
properties can vary from instance to instance.

Message-ID: <0003251501490F.21205@scorpio.redspice.com>

ok  so
I am trying to export a folder using import/export
I give an export id and click on export and I get an exception
however if i give an import file name and click on  export  I get a
filename.zexp  in the var dir. Isn't this rather confusing.  Do import and
export have their own
zopish meanings ?
I am seeing really weird stuff in 2.1.4  cant wait to upgrade to 2.1.6

Now that a beta version of Pike has been released (see

given any thought to a Pike compatible interface to Zope?  It's a cool
way to interact with a content-management system.

I hope you have got your answer ,  any way my 2 cents
ssi pales in comparision to
dtml. dtml makes template programming a breeze.  You will have to learn the
syntax and ssi statements have their equivalents in dtml and more. But zope is
best for dynamic stuff.   For static pages  I would stick with the http server.
For your problem I see coding some dtml to replace the ssi and refer to the
external cgi just as usual for creating the image dynamically.

I was just looking at that earlier today. I was thinking that it might be
fun to make some Pike-compatible stuff. Also, it might be interesting if we
can set up a preferences system on top of LoginManager that is compatible
with the UserLand spec.

Mmmm... interoperability.

I looked briefly at the XML-RPC spec this morning. It certainly seems
plausible to create Pike compatible interfaces for specific products. Zope
and Frontier work pretty differently, but from a content-writer's
perspective there does not need to be a difference.

The people who maintain the _other_ Pike (http://pike.idonex.com/) will
be happy about this -- not.

Why can't people do a little name research before they hijack somebody
else's name for their project? This new Pike will only hurt the original
Pike's reputation, possibly even forcing the latter into changing its
name.

Pike is the C-like, interpreted OSS scripting language that powers
Roxen, a web/app server that competes directly with Zope, as well as
this Manila/Frontier thing.

I'm sorry, the corrected text above is what works. What never works is
<dtml-with sequence-item only>.  The error I get with <dtml-with
sequence-item only> or <dtml-with _[sequence-item] only> are:

Do you see what I was trying to do?  I wanted to see if just the
sequence-item had the boolean attribute "noshow"

Ethan,

Try something like (tested, but not in this situation, i.e. I use it a lot
and it works YMMV):

<dtml-with "PARENTS[-1].net" only>
  <dtml-in "objectValues(['Folder'])">
    <dtml-in aq_explicit only>
      <dtml-unless noshow>
        do something
      </dtml-unless>
    </dtml-in>
  </dtml-in>
</dtml-with>

| Note that what you're describing isn't really part of ZEO, it's really
| more in the realm of what is already in Zope.  Thus, if you're eager to
| add such a feature, you already have what you need.  Start tinkering
| with the transaction machinery and see how you can extend it.

Except at the ZEO level, the conflicts must have been resolved.
I only want to replicate the state of play at the ZSS end.

Otherwise I could alter ZEO to take a list of ZSSs and do a 'broadcast' and
have them all do the same work (hoping like crazy that all transactions
arrived at all servers in the same order). Then I would have n copies of the 
primary ZSS. Failover from this point is almost trivial. 

The other option is to get the ZSS to forward transactions in the order
IT gets them and send them to a list of servers it knows about. This is
slightly cleaner, since all of the Zope machines don't need to know
about all of the ZSSs.

The other major problem is, that if I do this work, I will be unable to 
contribute it back to the project for some time (if ever). I don't really
have the facilities at home to be able to do ZEO type work, my current
employers (where I have more available resources) like OSS, but, tend to 
treat it as a code repository, rather than a symbiotic relationship.

netstat -a should tell you what ports are being listened to.  try 
./start -m '9898'
and if it works, well, then you've probably got something listening to
the monitor port.

Note that while http can be virtualized (listen on selective IP's),
monitor and ftp cannot, so you have to pick your ports accordingly.

Try this (untested), assuming the name of the method you want to call is stored
somehow in the variable 'methodName'::

  <dtml-let methodToCall="_[ methodName ]">
    <dtml-in list_hrefs mapping>
      <dtml-var "methodToCall( this(), href )">
    </dtml-in>

Brad Clements has done a bunch of work on melding Python with NetWare -- he was
to present a paper on it at the last Python conference, but couldn't get there
due to weather.  His paper was part of the procedings, anyway, and may be online
somewhere under www.python.org.  His e-mail address is bkc@murkworks.com.

I think I even remember reading that he had Zope up and running as an NLM.

Subject: [Zope] Returning sequences of values with External Methods
Message-ID: <38DC6718.5080501@messagemedia.com>

Currently, I am making a lot of external methods, and I would like to 
use one like this:

<dtml-in methodname>
  <dtml-var foo> <dtml-var bar>
</dtml-in>

So basicly, I want to return a list of named values (a dist of 
dictionaries)? Are there any pittfalls you guys can see in doing this? 
suggestions?

Should I make it a Product?

Subject: [Zope] Project proposal: The Gestalt System (using Zope)
Message-ID: <38DDD362.22728102@bigpond.com>

The Gestalt System project aims to develop a free, Open Source,
object-oriented software framework which makes use of other free, Open
Source software tools for the purposes of managing, analysing, and
reporting on quantitative data in a manner which is suited to modern,
networked computing environments in which processor, memory, and storage
resources are abundant but time is scarce and requirements are forever
changing. 

The Gestalt System may be of particular interest to Zope users because
we propose to use Zope to provide some important aspects of the
project's
infrastructure.

Full details of the project proposal can be found in the Gestalt System
Manifesto which is available at http://gestalt-system.sourceforge.net

I was very confused about this  - the only Pike *I* knew of, is the core language of the Roxen webserver (www.roxen.com), which has been going for some time. As the Roxen team are about to shift version 2 of their server it seems like some lawyers are going to get some bunce here :(

Subject: [Zope] Accessing ZSQL connection from external method
Message-ID: <v04220801b503b1dd8153@[134.76.23.194]>

Howdy!

I'm making heavy use of MySQLdb in my external methods. Now I just 
realized that ZSQL-connections are kept open permanently and it would 
save a lot of time if I wouldn't have to open a connection each time 
my external method is invoked but use the already existing 
ZSQL-connection instead.
My question: How can I access a ZSQL-connection (ZMySQLDA) from an 
external method?

--Ragnar

P.S.: I benchmarked MySQLdb and found that opening a connection took 
1.2ms on my systen whereas a very short request for authentication 
took only 1.1ms. So beeing able to use an existing connection would 
result in about 100% performance gain (at least at first glance).

Subject: [Zope] anonymous Products?
Message-ID: <38DE0A95.CF7CA9A7@imeme.net>

Zopistas,

I need to have a dtml-method that does manage_clone,
manage_changeProperties, and manage_users.

It has to let an anonymous user do this:  I have to set up accounts for
people automagically.

I cannot seem- either with a product or just a straight method- to give
it the permission it needs to be called anonymously.

If anyone could give me a hint as to how to achieve this, that would be
great.

I looked at http://yyy.zope.org/Register/register.html , but I cannot
seem to get the dtml code for the actual new-user-maker.

Answer: make sure REQUEST has confirm and roles:list properties (the
latter isn't absolutely necessary, but you'd just have to set it later
anyway.)

Subject: [Zope] Performance Testing / Expections
Message-ID: <20000326232738.A30471@bob.sesgroup.net>

Ok,

I know it has been asked a couple of times before on the list, but
there hasn't really been any absolute conclusions on the type of
performance to expect from zope and/or how to tweak it for the best
kind of performance.

Over the last two days I have been doing some testing and would like 
to hear on opinions if these results are similar to other peoples.

Firstly the machine specs are:

PIII 450Mhz
128Mb 
IDE Harddrive

Running Debian Potato

Zope is running through Apache with PCGI.

All tests were run using ab.

First I tested apache to see how fast it was as a benchmark.

1000 requests, 25 Concurrent.

/usr/sbin/ab -c 25 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

Results:

384 requests per seconds (rps). Avg wait: 54ms. Max Wait. 83ms. Throughput: 20MB/s

1000 requests, 1 at a time.

 /usr/sbin/ab -c 1 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

425 rps AvgWait: 2ms MaxWait: 3ms Throughput: 21MB/s

The I tested the same document servered statically through zope. (From zope's root)

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/testemc"

42 rps Avg Wait: 514ms MaxWait: 743ms Throughput: 2MB/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/testemc"

45 rps AvgWait: 21ms MaxWait: 29ms Throughput 2.3MB/s

Next on line was a moderately dynamic page. Dtml only, no DB or Ext. Methods.

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/sesgroup?cu
rrentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/siteinfo/index_html?"

4.97 rps AvWait: 4.4s MaxWait: 5.6s Throughput 21kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/
ecom2/sesgroup?currentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/
siteinfo/index_html?"

5.09 rps AvWait: 195ms MaxWait: 198ms Throughput 22kb/s

Then finally testing a page with the same amount of DTML complexity but
some external methods which call a database using pygresql

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps  Avwait 16s  MaxWait 20s Throughput 19.51 kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps Avwait 768s MacWait 789 Throughput 19.55 kb/s

In summary serving straight of apache is very fast, and doesn't suffer if 
multiple people access the site at once.

Static Zope (which you wouldn't really do anyway) was acceptable speed and
didn't really suffer too badly if there were multiple accesses.

Dynamic Zope was fair in speed, but proably still fast enough, at least for
my site anyway. It started to suffer in a bad way with multiple accesses, 
up to 5 sec response time.

Highly dynamic Zope was very bad in rps and hopeless more multiple access.

Now I have only been in this game I a while so I don't know how critical 
the multiple access thing is going to be. I am expecting at most 1000 
visitors each day (say a 10 hour period). So 100 visitor each hour shouldn't
cuase me any problems at the moment.

I guess how I would like to know if anyone out there knows how to improve 
this performance at all. Can I throw memory and processors at it and make
it go away? Obviously there are some things in the highly dynamic bit
which I will need to speed up, however how can I make just normal
dtml execute faster? The prospect of ZEO has certainly helped in this
area but surely I must be able to sqeeze some more performance out of this
machine.

Thanks in advance.

1. Generate Expires headers for your pages, and maybe handle
If-Modified-Since headers too (see OFS.Image.File for an example of the
latter.)  This lets the browser cache results of yor pages, which won't up
your requests-per-second but will reduce the number of requests you have to
handle.

2. Cache results of dynamic pages and then serve that up instead.  This can
speed things up by a factor of 5 for pages that are only a little dynamic.


I'll follow this up in a short while with an example of generating Expires
headers in DTML.

The following dtml code will tell the browser that the page expires one hour
in the future:

<dtml-call "RESPONSE.setHeader('Expires', _.DateTime(_.DateTime().timeTime()

Wild idea: Do you ever get errors when you try to compile a big, big
program, specifically the Linux kernel?  It seems as if a large number
of seemingly perfectly functioning PCs have memory errors that only
show up under specific, not well known access patterns.  Compiling a
big program is a process that can exhibit these error prone
patterns[1][2].  Perhaps Zope under load causes the same access
patterns?

[1] This is not an urban legend.  I have seen it.
[2] Search for gcc and signal-11 or sigsegv.  There are a couple of
    web pages out there about this.

I get them constantly when recompiling Mozilla, which is a daily task almost.
And bad_slab_magic, and random segv's.

I'll be running a good memory stress test soon, to see if I can pinpoint the
offending Mem. bank.

You can embed SSI within Zope. I'm currently writing a How-To on it.
Depending on how complex your inclusion is, you may be able to get away
with using Apache rewrite rules. If you want to embed the SSIs within
your Zope pages, you can resort to using SiteAccess and a call to
Client.call. Take a look at the thread "How to serve PHP within Zope"
for a more detailed explanation of what I mean. I should have the How-To
finished soon. If you are in a rush, I can send you a draft.

Well, that is food for thought today. If anyone has some really good
analysis of this (since this is my first time using AB) that would be
great.

netstat -a shows only ssh, http, smtp, sunrpc, and syslog sockets open.  
Nothing too wierd.  Like I said, using other socket numbers (e.g. 9898)
doesn't seem to fix it.

I can offer you an NDS user folder if you're running Zope on Windows or 
NetWare itself. For Linux, I suggest using LDAP

Message-ID: <Pine.LNX.4.10.10003261217150.15096-100000@odeon.net>

	Greetings,

	I've got a form that has three fields.  One for year, one for day,
	and one for month.  The selection parts of the form are similar to
	the following:

   <select name="date_mm">
    <option value="01">January          
    <option value="02">February     
    <option value="03">March
    <option value="04">April     
    <option value="05">May     
    <option value="06">June     
    <option value="07">July     
    <option value="08">August     
    <option value="09">September     
    <option value="10">October   
    <option value="11">November     
    <option value="12">December    
   </select>


	What I'm trying to do is pull the 'date_mm' (along with the other
	two fields, 'date_yy' and 'date_dd') into the namespace area so I
	can do something like:

  <input type="hidden" name="event.date" value= \
    "<dtml-var var_yy>-<dtml-var var-mm>-<dtml-var var-dd>">

	I would expect that I can use something like:

  <dtml-call "REQUEST.set('var_mm', 'date_mm')">

	However, that doesn't work like I'd hoped.

	Any help would be greatly appreciated,

	Jeff

Subject: [Zope] dtml-tree question
Message-ID: <20000326221801.A17865@owl.rhein-zeitung.de>

Hi, 

I have a problem with dtml-tree. But I think that is just a problem I have,
cause I don't completely understand the dtml-tree thing.

I have the following dtml code snippet

<dtml-tree skip_unauthorized=1 branches_expr="objectValues('Folder')" sort="order">
    <dtml-if "'index_html' in objectIds()">
        <a href="<dtml-var tree-item-url>" target="contentframe"><dtml-var title_or_id></a>
    <dtml-else>
        <dtml-var title_or_id>
    </dtml-if>
</dtml-tree>

Well, I traverse my folder structure to build a nice dtml-tree from it. So far
the insertion of links, the if-clause of the dtml-if statement, works really,
really fine. But I also want people to be able to click on the elements that
are part of the tree, so that they don't need to click on the plus signs but
can also click on the text next to the plus sign. This is the else-clause in
the dtml-if statement. But everything I tried didn't work. 

Is is solveable? And how? Or do I have to build my own tree using a recursive
call of a dtml-in loop?

Bye, Oliver Andrich

P.S.: For all of you who have seen my questions about users, roles, and so on.
I like to tell you, that I am writing a HOWTO on this, so that people don't
have to dig into the information and bother people with questions, as I did.

Looks to me like you're close...

<dtml-call "REQUEST.set('var_mm', date_mm)">

Note that there are no quotes around date_mm. Assuming that this DTML is in
something POSTed to by your form, date_mm will be available in the
namespace, and you can use it like a normal variable.

Your question is not quiet clear, but I will make some assumptions and then 
try to answer it:

I assume you want to do that all in the same file, without sending a form. 
In this case what you want to do is not possible, because you ask the 
server to know something which does not exist yet.

A form is created in the moment the user submits it. So here is how you do it:

FILE: someForm

...
<form action="someAction">
   <select name="date_dd">
      <option value="01">01
      <option value="02">02
      ...
   </select>
   <select name="date_mm">

So you combine your date AFTER the form is transmitted. I cannot think 
about a case, where you need it differently. If you have one, you should 
revise your design, since weird syntax is mostly due to bad design.

Ben,

Hi...

This topic is probably better suited for the main Zope mailing list so I
moved my reply to it there.

Err... we'd all love to see better docs written for this process.  Maybe
you can write them once you get it done.  :-)  No, Zope does not
necessarily need to be installed from source, but I think the MySQLdb
stuff needs python include libraries.

Can you give more specific questions about your problem?

Some hints anyway:

 - the MySQL development libaries need to be installed on the machine.
 - python 1.5.2 libraries should be installed on the machine

Yeah I am currently thinking of the best way todo this. I guess I now reach
another point. Does anyone know how to make External Methods persitent, or
would I have to store cached information on the filesystem. Does ZCache work
for External Methods, are there any plans todo this? I don't mind writing
code for ZCache todo this if the current framework easily allows this.

Thanks,

Benno

 I usually  create python classes instead of plain external methods and
instantiate them  as zclasses. This way I can cache information with inthe
python class as class members. If there are hooks in the zope framework to do
somthing similar (ie make use of zcache etc) please post

Not convinced that's it tho.

Side-note:  I've patched ZServer/medusa/asynchat.py line 255 - the 'first'
method - to check if self.list actually has anything on it before
returning:

        def first (self):
                if self.list:
                        return self.list[0]
                else:
                        return None

Since I did that, I haven't been able to reproduce the crash.  I doubt
that's the problem as such - I'm still leaning toward a race condition
somewhere - but the fact that it hasn't crashed since then is curious...

Oh, and strace'ing and adding debug and so forth seems to cause the problem
to display subtly different behaviour - which makes me unhappy...

Hi there,

<dtml-var str> ofcourse I get 12345678.
How can I display only part of it ? Say the first 4 chars

In python I know this can be done with something like
str[:4], str[4:6] and str[6:].
Any help ? (Hope I didn't sound too newbish !).

Subject: [Zope] Passing data to/from Python
Message-ID: <NCBBJGNEKLKGLMECHMLGIEFOENAA.wexler@ccr.jussieu.fr>

Dear Zopistas,

I am in the process of learning about Zope, and trying to
determine whether to make the switch from pure Python CGI
scripts. If someone could answer the following questions (and I
apologize, as it will probably seem naive), it would really help.

Let's suppose I have a page where the user queries a data base,
for instance a telephone directory. The telephone directory is in
an Excel file. At present, I have a CGI script that opens an
ODBC.Windows connection, executes an SQL query, and outputs the
results (names, phone numbers) as an HTML table using "print".

What is the best way to do this in Zope? Here are the points that
I don't get:

1. It seems that the only way to establish a DB connection is
through Gadfly. There are warnings everywhere that Gadfly is
inefficient. Therefore, I want to use ODBC (ODBC.Windows), like I
did before. How?

2. I might eventually need to do complex calculations on the
retrieved data, so I would prefer using Python code in an
external method, rather than a DTML method. In order to get Zope
to accept the line "import ODBC.Windows", I had to copy the ODBC
and DateTime directories from my regular Python installation
(PYTHON/lib) to ZOPE/bin/lib. But then, when I try running the
script, I get one of the following problems:

   a. If I go through authentification, the script runs, but I
   cannot establish the connection to the database.

   b. If I type in the URL of my search page directly, without
   authentification, I get a Zope error: "initialization of
   module mxODBC failed
   (exceptions.AttributeError:mxDateTimeAPI)".

Is my ODBC.Windows installation wrong, or do I have a more
fundamental problem?

3. What if my Python function in my external method wants to
return information to my DTML method? For instance, how do I
return a Python list, and what do I do in my DTML method to
process it (e.g., output a line for every member of the list)?

4. The way I call my Python function now is through the <form
method="POST" action="search"> tag, where "search" is the
external method ID. The form has a field called "name", and my
Python function has an argument also called "name", and so it
recuperates the string that was entered in the "name" field. Can
I pass the "name" as an argument to a DTML method?

If these questions have answers, I would really appreciate them.
Otherwise, if I'm completely off-base (for instance, if I'm
thinking in Python terms and not in Zope terms), please point me
in the right direction!

Thanks in advance.

Nonono.... ZOPE uses the Gadfly db to store "zope objects".  It can also
connect to other DBs, and access them via SQL methods.  There are a number of
DB interfaces, including an ODBC interface.

afaik, you can simply return a list.  As for iterating through the list, you
would use <dtml-in myMethod> stuff goes here </dtml-in>

All fields passed in a POST are available via the REQUEST.form map.  Also, so
long as they don't match the name of other objects in the namespace, you can
access then directly.  So, your 'name' field will be accessible:

<dtml-var name>  <-- assuming you don't have any other objects called "name"
<dtml-var "REQUEST['name']">    or
<dtml-var "REQUEST.form['name']">

Gadfly is just one of  the db's you can use. The aquaduct product family gives
you many options
 look at http://www.zope.org/Products/DA/ZODBCDA for the ODBC
adapter.  This is defenitely the easier way

You can do quite a bit with dtml unless of course you prefer python  and
sometimes it is easier to do stuff in python,  dtml is not a replacement by
any means

return a list and process it using  <dtml-in > which behaves  very similar to a
database cursor 
>  Can

Absolutely with the dtml  programming you can do the same things and more 
All the form variables show up in the REQUEST object and become part of the
namespace in your script,you can use them like any other variable in the
script

There's an ODBC database adapter for Windows machines.  It does not work
under UNIX.  The Sybase DA works against MS SQL Server 6.5 and below
from UNIX.

Look under "Downloads" on Zope.org.

Also read the ZSQL User Guide.

Hmm.  I've never seen ODBC.Windows.  We've punted on supporting ODBC
under UNIX, and we're now supposed to be contracting out to some other
folks to provide it for us.  Not sure when this will happen.  You can
try to write your own ODBC DA for UNIX/Linux.  There is a HowTo on
writing a DA someplace out there that Chris Petrilli wrote.

external method named "pyfunction":

def pyfunction(self):
   return ['1','2','3']

a dtml method that uses pyfunction:

<dtml-in pyfunction>
   <dtml-var sequence-item><br>
</dtml-in>

Should output:
1
2
3

If you use an external method to handle the form input, you should be
able
to get at its attributes by looking in REQUEST ala:

def myformhandler(self, REQUEST):
    a = REQUEST['a']
    b = REQUEST['b']

where 'a' and 'b' are form field names.  This can also be done by:

def myformhandler(self):
    a = self.REQUEST['a']
    b = self.REQUEST['b']

Hey Mark,

This is your lucky day... Zope does this without even blinking... I 
would say (and without starting a flame war) that Zope's ability to 
easily connect to databases is one its best features. To the 
questions...

1) Gadfly is the example. You connect to anything that there is a 
ZSQL connection product for (Oracle, Sybase?, PostGreSQL, MySQL, 
Gadfly)

2) You get back the data and can do anything you want with it. You 
can parse it, calculate it (although you might want to look into 
doing some of it in SQL) or just spit it out. Authentication has 
nothing to do with what you do with the data.

3) It is easy in DTML, just do a <dtml-in> to go over the list.

4) Yup. You build a form and send that form to a DTML method that 
processes the form. If you are super slick you have it in the same 
DTML method.

Don't worry about thinking in Python terms. I came from Python.. 
thought Zope was going to be easy, found out it hard than studied up 
a bit and now respect it. There are a LOT of things you can do in 
Zope, most of them "like" things you do in Python, just stated a bit 
different. The DTML reference guide is your buddy. You read that and 
come back here when you are truly stuck.

Now go Zope...

:)

Ok.. my mistake.. sorry.... thanks for correcting me.  I was under the
impression ZOPE stored data in a db, using gadfly as the default, and it was
refered to as ZODB for convenience.

Thanks for clearning that up for me.

Subject: [Zope] Problems with adding ZClass instances
Message-ID: <14558.57262.760790.737744@antares.int.plain.co.nz>

I'm have problems with a ZClass I'm working on that uses Folder as
it's base class and is supposed to install a set of default methods
when it's created. The trouble is that it won't when the webDirectory
is created, but it will when I invoke the same method from a tab afterwards.

Here's the body of webDirectory_add:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-if createDefaultMethods>
   <dtml-in "default_methods.objectIds()">
   <dtml-try>
      <dtml-call "manage_delObjects(ids=[_['sequence-item']])">
      <dtml-except>
      </dtml-try>
     <dtml-call "manage_clone(
            _.getattr(default_methods, _['sequence-item']), 
            _['sequence-item'], REQUEST)">
  </dtml-in>
  </dtml-if>
</dtml-with>

I'm assuming that the code within the <dtml-with ...> is effectively
opperating in the context of the newly created object, but when the
first manage_clone() is executed, it bombs out in _getCopy,
tripping over on this line:

ob=container._p_jar.importFile(f)

...because whatever container is, it's not a folderish object. 

So what do I need to do to switch to the new webDirectory object at
creation time, so adding methods is automatic?

Thanks,
John.

 Actually the limit is 4 GIG. however ext2 FS on Linux has a 2 gig limitation 
you can use a patch that will take it to 4 GIG, its available on the ext2 home

First of all, someone needs to let you know that data should never be 
stored in an Excel file. Anyway, what you would do is use the Zope ODBC 
database adapter. The Gadfly one is the only one installed by default, 
but others are availible at zope.org

You really should be storing that in a relational database though. 
Speaking for years of database experience, Excel is never a good place 
to keep things.

This isn't really a Zope issue. It's a bug in your script or the serveor

Ask those in the ODBC.Windows mailing list; this is not a Zope issue.

You might consider though, not using so many external methods and 
whether writing packages - they are more powerful and can be more 
powerful. External Methods are usually for quick one-timers.

I beleive you can do just that - return it as a list, and use it like 
this inside DTML

<dtml-in externalmethodid>

Hang in there. Learning to do this kind of thing in ZOPE is hard - I 
know because I'm trying to do it myself.

<dtml-var "search(name=name)"> should do the job, if I understand your 
question right. (Works like in Python.)

And remember: If you want performance, use any OS other than Windoze. Two 
good free DBs are PostGres (currently in 7.0 beta 3, yeah!) and MySQL. If 
you go to the RedHat site and sign up, they will send you Oracle 8i for 
free (or do they not do that anymore). I think Sybase has a similar 
promotion program. For all these DBs you have Zope DB Adapters.

Zope is cool, the docs are a big issue (I know), but a lot of people work 
very hard to change that. If you have suggestions of how to improve them, 
mail: Zope Documentation Project <zdp@zope.org>. Thanks.

Stephan

sorting is ascendingly by default (taken that you put a sort in the
dtml-tag, like 
<dtml-in sort=id>)

turning the sort to descending is done by putting in 'reverse', like so
<dtml-in sort=id reverse>

It is always ascending unless you specify "reverse" as an attribute with no 
argument in DTML-IN

<dtml-in "objectValues()" reverse sort="id">
   ...
</dtml-in>

Message-ID: <000601bf97c5$3590d960$0200a8c0@digitalview.com.hk>

Hi

I've got a load of files (PDFs, TIFs) that needs to be accessible from
within a Zope application. I need to be able to link to them so people can
download them. What is the best way to go about it?

If I add them into Zope (ie [Add new item]>[File]>[Browse]... etc is there
an easier way of doing it? I've got hundreds of files to add and I don't
want to do it using the HTML interface.

If I have the files in directory outside of Zope how do I reference them?
Bearing in mind I only need to link to them for download, no need for the
information in the files to be accessible by Zope.

thanks

By searching of the documents using ZCatalog, in query I list words with

with "OR" there is a word that is not in the index, ZCatalog finds nothing,
for example, "web or pop or mailvvv", but the documents with "web" and
"pop" exist. On www.zope.org the same effect. Is it possible to correct
this situation?

Subject: [Zope] zope search problems w/squishdot with latin1, locale fi_FI
Message-ID: <200003270923.MAA02125@katto.kaapeli.fi>

I'm using Zope 2.1.4 on Linux with environment LC_ALL set to fi_FI and
Zope started with -L fi_FI, and ZCatalog indexing & searching seems to
work fine.  (well, there's a problem with some documents having &auml;
etc. spelled out, but if ä is used everything works OK.)

BUT, ZDConfera & Squishdot don't work right.  For some reason, at some
phase of the indexing characters like ö (&ouml;, octal 366) in words
are converted to their octal codes.  This can be seen by looking at
the raw Data.fs file.  The result is that when I have a word like

kökköviesti

in the ZDConfera or Squishdot article, it can be found by search as

366viesti

It is converted in the db storing/indexing phase to something like
k\366kk\366viesti, which is then broken into words k, 366kk, 366viesti
which are stored into the textindex.

Any ideas on how to fix this?  I've looked at Splitter.c,
TextIndex.py, ZDiscussions.py and Squishdot.py, but I can't find
anything which would convert characters to their octal codes.

Aha! I have it!

Your external methods are given a pointer to self as the first
arguement.  You can use this to access any methods in the current
folder (self is the current folder)  So just call:

self.MyZSQLMethod(arg1, arg2)

where arg1 and arg2 are would be the arguments for the ZSQL Method.

Yes I am using postgres, however I am _not_ using the postgres adapter. 
I am using External Methods and python to do all data access since the data
requires formatting after it comes out of the database which is much
more easily done in python cf. dtml.

   Then you loose all the data caching done by the ZSQL methods.

Alas! It doesn't work.  It appears to fall down on the line:
  <dtml-let methodToCall="_[ methodName ]">

Traceback:
  File C:\PROGRA~1\Zope\lib\python\DocumentTemplate\DT_Let.py,

It seems evaluating this doesn't just give the string contents of the
dictionary item, it evaluates the actual external method call.

I think I'll have to give up at this point and take the cludgy option
(unless anyone can think up another way).

Thanks for your help.

Yeah I know, which is a shame, however the postgres db adapter is only a
development version and as I said we need to manipulate the data in python
before it comes out of the db. I plan on putting in my own caching routines
here, however this will still only get me up to at most 8 request per second,
which is proably reasonable for my application.

Cheers,

Hello,
i'm testing Zope 2.1.6 with Windows NT 2000. Everything is running fine
but... it's
slow updating the internal database. Each time you press the "Change"
button the wait is 30 seconds! On the same machine with Windows98SE and
Linux there is no wait.
All the other operations are working without any problems of speed.

Is there anyone else who tried Zope with Nt2000?

Thanks,

Message-ID: <38DFE1F7.290CCF16@hal.varese.it>

Hello,
i'm a fan of statistics, i want to know how many hits my sites have
received, from which country, how long, etc. etc.
I run several programs to analyze the logs from Apache and Zope but, i
don't know how to split the log files of Zope for different sites.
In my situation i have some web based only on Apache, as virtual hosts
where i can specify which log file to use for that single entry; some
are on Zope, virtual hosts done using SiteAccess and ProxyPass. Mine
problem is that i want one single different file for every virtual host
i have on Zope.
Is there a solution?
I also have problems with kill -hup, it doesn't work with python, so to
take the daily log
i have to stop Zope, take out the log and then start it again. Ok, it's
not a big problem, but that single minute of pause it's not making me
happy!

Thanks,
    Bruno

I'm running my dev-server (2.1.4) off my
win2k-box..(P2-400Mhz - win2k professional)
Usually, updating is close to instant, but occasionally i
experience 20-30 second hangs when updating.. Never thought
of it as a problem, though , as the machine is not a dedicated server
and i run a lot of stuff of it simultaneously (browsers,
photoshop,etc..)

This I cannot understand, what's new ;-)
I've mocked it up in the attached .zexp if anyone wants to try it out themselves.

I have a site with a subfolder. This is private and so has 'view' permission only to a 'user' role
and the usual 'manager' role.

I have a file, index_html in the mockup, in this subfolder, which includes an image called 'black'
from the root of the site. The root folder has 'view' granted to the anonymous user.

I added my users with the 'user' role, user1 in the mockup - password 'user1', to the subfolder's
acl_users . However, when I went to view the subfolder and logged in as user1, the page loaded fine,
except for the 'black' image. I was asked to authenticate again but the only way I could get past
this was to use user2, password 'user2', who has manage access to the whole site. 

This is really confusing as 'black' comes from the root of the site, which is viewable by even the
anonymous user, and viewing the black image on its own in another browser session, even using the
URL from the HTML generated for the subfolder index_html, worked fine and no authentication was
requested.

Obviously giving these users manager access to the whole site was unacceptable. I managed to solve
the problem, see user3 - password 'user3' in the mockup, by creating the user in the root acl_users
folder and giving them no roles. Then, giving them 'user' as a local role in subfolder.

I've tried this with Zope 2.1.4 and 2.1.6 on Linux and NT4, Netscape 3.04, Netscape 4.7 and Explorer
5.1 all with the same result.

Anyone know what's going on?

Chris

I had the same question, and found the answer in the code of the SQLSession
product.. I haven't tried coding it myself yet, but its does exactly what
you (and myself) are trying to do...

I have used <dtml-try> but it does not work.

Anyone have another way to handle this error?

If you want to use pythonish expressions in a dtml-var tag, just quote
them.

e.g., <dtml-var expr="myStr[:4]">  will get you the first four
characters of string myStr.  The 'expr=' part is optional.

Message-ID: <002d01bf97f7$73216d30$0980b1c3@net22.net>

Hi there,

I'm trying hard to make my Oracle8i  (Oracle 8.1.5.0.1)  for Linux  on
Redhat 6.0 with Python 1.52 plus python-devel installed from rpms and Zope
2.1.6 talk to each other...


As I understand so far, I first have to

Right?

I tried the new Oracle8i  setup-file provided on www.zope.org, I also tried
both Setup-Files provided with DCOracle, but everytime the same.

By the way, I suppose that there is no problem with the Oracle
client-library setup, because I am already connecting to the Oracle8i with
PHP.
I've never had problems with Python installed from rpms? Did anybody else
have?

some additional data points on those crashes:

in my test setup (CVS checkout using ZOracleDA) i found the following
ways to avoid crashing:

- using Pavlos' cure (setting DEBUG=1 in asyncore.py)

- manually closing the oracle database connection or deleting it (which
renders the membership components of my site useless since all that info
is in oracle)

- calling the offending page directly in a python interpreter by talking
to ZPublisher and circumventing ZServer

my suspicion is some weird interaction between the database adapter and
ZServer.

How can this be fixed?  

I can probably figure out how to make sure libpq (postgresql API
library) is reentrant (it might be already).  What has to happen to
the DA to make this work?

And if this was done, could you configure the DA to open, say 5
backend processes and use them in turn?

Thanks for your input.However I'm not sure that i really understand it. I
guessed that in that method the key element is popertyMap. So I tried:
<dtml-var propertyMap> in my zclass_addForm.

When i tried to add a myzclass instance anywhere in the ZODB hierearchy i get:
({'id': 'title', 'type': 'string'},)
Not exactly what i wanted. I wanted to get the ids and types of the
propertysheets properties.

Here is the purpose. I found that the default method of adding ZClass instance
is boring. The form asks you to type the id, then you can add your instance and
after that go to the propertysheets/myproperty/manage method to fill the
propertysheets properties.

I think that most of the times it's better to fill these properties when you
create the instance. So i began to modify each time, the addForm to include
the propertysheets properties in its form. It worked fine but each time i
create new ZClass i have to modify manually the addForm. So i tried to create a
generic addForm that could work with any kind of ZClass no matter what are the
propertysheets properties.

That's why i wanted to get the ids end types of the propertysheets properties of
a ZClass from outside the ZClass.

I can do that by creating an instance, taking the needed information from that
instance to generate automatically the addForm, creating a new instance with
the addForm then deleting the instance from where i got the required
information about the propertysheets. It works fine but it's not very elegant
and may a source of potentiel problems. Here is a "addForm" code that works:

<form action="ebook_add" method="post" enctype="multipart/form-data">

<table> 

<tr>

    <td><input type=text width=25 name=id></td>

Another possible solution would be to create a new instance with temporary id

Yellow,

I don't know about all you but I'm trying to use MySQLdb  0.1.2 on NT4 +
SP6a + Zope 2.1.4
The Installation Instructions aren't to precise on using it on win32
platforms and Zope doesn't show me the MySQLdb on the product list. Is there
some special steps to install it on NT?
I've seen the instructions page on zope.org and I know about having to aplly
the patch and compiling the .py on unix systems.. but what about win32?

anyone?

To use the propertysheet before you have an instance, you need to get the
Product into the namespace stack, something like this (untested, but I do stuff
like this elsewhere)::

  <dtml-with "manage_addProduct[ 'MyZClassProduct' ]">
   <dtml-in "MyZClass.propertysheets.info.propertyMap()">
    ....
   </dtml-in>
  </dtml-with>

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Hi,

I've Zope 2.1.4 running on NT4.0, using ZServer.
I would like to set up IE5.0's "Web Folder" feature
for Zope, with Zope's authentication. I could set
up a web folder, but it doesn't do authentication,
so I can't've any PUT rights...

Any thoughts?

Thanks

You should be running Zope with -D option and no -Z option, ie not as a
deamon. Then you will be able to see the connections that come in and out.
Seems though that there are two (or more) problems.

I don't think I'm following you - what do you mean 
by "it doesn't do authentication"? After setting up 
a Web Folder pointed to a folder in your Zope 
installation, what happens if you try to drag a file 
from your desktop to the Web Folder?

Has anybody seen this before? I seriously doubt my maxusers setting is
the problem -- this usually indicates an infinate openfile loop. Anyway,
the short of it is that Zope isn't starting. I'm using FreeBSD 3.4 and
Python 1.5.2.

Oops!

Sorry, folks. Stupid IE problem. I don't know
what happened, but went to MS site, downloaded
5.01 and did a complete re-install, and it is
working fine, now.

Another thing - would it be possible
to've https for ZServer webDAV? I'm trying
to push Zope's use in my organization, and
right now, am toying with the idea below
(because FTP is ruled out by our security
guy).
  - Run Zope as a webDav server
  - IE5.0 as client
  - People who want to post content to the HTTPD
    server (which is IIS3), just drag and drop
    from their PC to the Web Folder.
Issues as of now:
  - How to get the content to NT folders rather than ZODB?
      localFS does not permit uploads... May be I'll try ZMirror.

I work for a non-profit organization and right now we are
not in a position to adopt IIS5 or NT2000. Nor do people
want to go for Apache + Linux. And I could'nt find out
any other affordable webDAV server for NT.

Zope has got lof of people excited in my workplace and
that is also one reason I want to push for Zope.

Message-ID: <00032712571600.01015@modemcable215.47-200-24.mtl.mc.videotron.net>

In the Z Class tutorial (page8) I read:

"Property Sheets also allow more indirect access to properties via the
propertysheets attribute. ... we could access the 'title' property via
propertysheets.stuff.title attribute in addition to simply the title attribute.
The sort of access is handy in the case where two different propety sheets
define properties with the same name."

Sounds great, so I tried to use to it to create a sort of "international" class:

myClass:
    propertysheets
        english
            name
            description
            .....


but if i try:
myClass:
    propertysheets
        french
            name
            .....

i get the following werror message:
Invalid property id, first_name. It is in use.

So it seems that contrary to what suggests the Z Class tutorial it is not
possible to have two properties with the same name in the same ZClass even if
they are in different propertysheets at least when using the management tabs to
add a new property.

Is it a mistake in the tutorial or is there another means to add a property
with a same name in another propertysheet without getting an error?

I was just about to implement a similar method, and it occurred to me that I
would have to give a proxy role to the method so that it could add a user.
Have you tried that?

I do something very similar in the ZGotW product's root factory::

 <dtml-in "defaults.objectIds( 'DTML Method' )">
  <dtml-let si=sequence-item>
   <dtml-with newRoot>
     <dtml-call "manage_addDTMLMethod( si, '', defaults[ si ] )"> 
   </dtml-with>
  </dtml-let>
 </dtml-in>

The key here may be the inner '<dtml-with newRoot>', which is forcing the
newly-created root folder to the top of the namespace stack, so that
'manage_addDTMLMethod()' is being invoked on it, rather than on the
sequence-item.

Hope this helps!

Subject: [Zope] date property format
Message-ID: <20000327195040.3288.qmail@hotmail.com>

Hello you all!

I have a timestamp, for instance, 2000/03/27 19:57:53.9808 GMT.

Lets say I have a document property, type date, where I want to
store this timestamp.

I found that the use of A or B is different:

A)

	<dtml-call "REQUEST.set('Prop1', ZopeTime())">
	<dtml-call "manage_changeProperties(REQUEST)">

B)
	<dtml-call "REQUEST.set('Prop1', ZopeTime())">
	<form action=manage_changeProperties>
	<input type="text:date" name="mydate" value=<dtml-var Prop1>
	<input type=submit>
	</form>


The difference arise when formating for presentation:

A)
	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 18:57

B)

	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 19:57

Note: the 1 hour difference.

	I guess the difference is in the "Prop1:date" that forces
zope to create the correct object with all the information needed to,
for instance, recognize the GMT change since March 26.

	I found that using another kind of presentation format will
bypass this problem, i.e, instead of fmt="c style", I use functions like 
dd(), mm(), timeminutes().

	Is there a way to make the code A tell zope to create a
correct date object(property)?

My best regards,
Júlio Silva

Subject: [Zope] Creating Python class instances via DTML
Message-ID: <38DFC3D2.92037BD3@www.ifopen.com>

Greetings,

	I have created a Python class (Lead) and added it as a product and
am able to create and edit instances via the managment interface.
However,
I have run into a wall when trying to do so via DTML. Taking the path
used
in the "Adding ZClass Instances Programmatically" HOWTO, I've tried
things
like:

	<dtml-with "manage_addproduct(['Lead'])">
	<dtml-call "manage_addLeadForm">
	</dtml-with>

where "manage_addLeadForm = HTMLFile('leadAdd', globals())" appears
within
".../Products/Lead/Lead.py" and "leadAdd.dtml" contains the form used
to populate the object fields. I continually get "NameError's" on
"manage_addLeadForm" so I'm guessing that I'm have namespace issues.
Can anyone point me in the right direction?

				Thanks, Bill

Sounds like you want to roll the results into a ZRDB Results object,
like an sql query results object.

from Shared.DC.ZRDB.Results import Results

I'd suggest that you take a look at Shared.DC.ZRDB as well as Ty
Sarna's TinyTable Product which does this in a more simplistic
manner.

One of my product has a LocalFS descendent class, where I can upload
files. Well I simply use a Zope file object for uploading, then I save
the content of the file object into a NT folder. If it helps you I can
send this code for you.

Is there a way to do this using Zope-zserver, and not Zope-pcgi?
When I started this, I was just using the Zserver....but now that I need
to include calls to cgi programs for the sake of a couple images, I am
thinking I will needs Zope-pcgi..

If this is the case, I will need to uninstall the Zope-Zserver (if I try
to have both, there is a conflict) and install Zope-pcgi.  Does this mean 
I will have to import all the files, directories, etc. back into Zope, and
then reconfigure all of the files (replace all SSI lines with
dtml lines, etc)?


Thanks,

Made no difference here either.

In desperation, I moved the server behind an apache using fastcgi. Same
problem persists...random crashes with aaiiieee 11 and 256 in the debug
log, often with core dumps.

May be time to move away from the Lintel box (stock redhat 6.1, 2.16 src
install, pII350, 256mB ram) - I don't see this on a sun box I'm also
running.

Does this happen with binary installs ? Is it just redhat 6.1 (we didn't
see this on 5.2!)? One problem is that the zmonitor usually works - the
server restarts itself and users may only notice a long delay. I see it
because I'm watching the logs anxiously.

True, I still get the restart problem. What the DEBUG=1 solved was the
mysterious exits without core dumps or debug notices under very little 
load (I cannot still grok why it would kill the monitor process too).
Under high load we still get crashes but at least now when it dies the
monitor process will usually restart Zope.

We are also running behind FastCGI but as you have experienced too, we
still get the crashes, at least every 5-10 hours sometimes more
frequently. (And we have no DB connections or any weird code.)

About to give up ...

MySQLdb is the python client (driver) for MySQL.  ZMySQLDA is the Zope
Database Adaptor which interfaces with MySQLdb to access the MySQL database.
As far as getting it to run on NT,  good luck.  

Under Debian the whole process looked like this:
  apt-get install ZMySQLDA

I let some poor Debian developer worry about how to configure the two and
make it all work.

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Well, I just moved my zope to a Solaris box rebuilt with gcc.  I'm now
able to CONSISTENTLY get this thing to crash.

What i do is point a couple of wgets at the box to recursively snarf
up pages.  This doesn't seem to cause any  problems (yet)

Then with my browser, I try and load up some pages.  Usually, within
four or five attempts at loading pages, BAMM zope starts eating up CPU
cycles and within two minutes zope crashes...

And this is what the debugger tells me:

Program received signal SIGSEGV, Segmentation fault.

Yes, at one point, in desparation, my method had all the rights I could
grant it :)  It turned out that you have to give the rights to the
object you're cloning, too.

Hm - what we need is someone running on Solaris who can get
crashes, who also has access to purify. We're moving from
linux to Solaris at the moment, and I'll be getting hold of
purify to try and track down this damn problem.

Jon 

I did a search on the web and found out a few complains about programs
compiled with gcc seg faulting. One posting mentioned a faulty
implementaion of the pow() call, of course I have *no clue* how or why it
causes problems in Zope.

One more thing.
Can you try disabling multithreading by giving the option -t 1 to z2.py?

Good to be able to reproduce the problem. I suppose I can call it progress
...

Subject: [Zope] multipart content type
Message-ID: <38DFFDC2.AF2335FA@adroitnet.com.au>

Hi,

I need to get zope to server multiplart content.  The problem I have is
that Zope always puts its own header with a content-type,
content-length, etc on each RESPONSE.   Is there any way to stop zope
doing this?   This is a problem because the RESPONSE specifically needs
to look something like this:

        Content-type: multipart/mixed

--Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: application-compressed/zip

      {contents of .ZIP file, character for character}

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: text/html

      <html>
      <head>...</head>
      <body>...</body>
      </html>

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!--

I can set the content-type that zope returns by using
RESPONSE.setHeader, but i cannot control what else is put in the header,
and the order of the header attributes.  This causes a problem with
multipart messages because the boundary string needs to directly follow
the content-type: multipart/mixed, and the first message part
content-type needs to directly follow that.

Any suggestions?

Hmm... if you just want to check that everything is there, try
(untested):

<dtml-if "_.len(REQUEST.form) > X">
  render page
<dtml-else>
  go back and fix it
</dtml-if>

where x is the number of variables in your form.

Yes you can but it is more involved than the management interface. Can you
log in into the management screen of a different folder? Then you can undo
from there.

Yes and no :-) Your product's add method creates a folder object, then 
switches to it and adds the default methods with each appropriate add
method. What I was trying to do was add a ZClass based product with
the createInObjectManager method, then use manage_clone to copy my
default objects across. 

It turns out I was doing this from the right place (inside the
dtml-with that is used to create the object), but manage_clone is
broken - it let you copy objects into a thing you've just created
inside the same method at all. I'm pretty sure this is a bug - I'd be
interested to know if anyone has actually got this working at all.

In the process of testing this out, I discovered another piece of
unexpected behaviour - you can do this:

<dtml-with "manage_addFolder( rootID, rootTitle )">
</dtml-with>

...and you can then switch to using that object straight away, but if
you do this:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
</dtml-with>

...the object you've just created doesn't appear to exist as far as
the rest of your dtml method is concerned. 

So I've got something working, using the various object add methods,
but I need to make sure I have one for each type of object in my
default set, and I have a feeling that I'll need to recurse into
folders to add those and their contents. 

Thank,
John.

Just curious, but I am using a rewrite rule from apache (same things happens if
append the folder to the URL using site access) and the controls for the calendar
keep appending the root folder of the site. For instance, jobs.domain.com
correctly displays items from the /jobs folder in zope, but the calendar controls
keep appending jobs as I navigate the calendar like after a few times I get
jobs.domain.com/jobs/jobs/jobs/jobs/jobs/myCal.

Is there anyway around this?

Arg! I don't seem to be able to add anything other than DTML methods
and properties inside a Zclass creation. So it looks like I'm back to
doing it all by had. What a time saver...

Graham

please correct me if I'm mistaken - having read the How-To it seems that it
only allows you to get at the *contents* of the files. All I need is a
pointer, a reference, to the file so someone can download it.

Anyway I tried it with the following:

<dtml-var standard_html_header>
<h2><dtml-var title_or_id></h2>
<a href="<dtml-var "support['brochures']['brochure.pdf']">">Test Doc</a>
<dtml-var standard_html_footer>

When I view this in the browser I get a 'Save to file' dialog, I duly saved
the file (it was an HTML file) and on viewing the saved file I can see that
it does indeed
contain the contents of brochure.pdf(!), which is not what I want.

To re-phrase my original question - how do I construct a URL in Zope such
that it can refer to a file on the local filesystem?

thanks

The traceback is in error_tb -- try <dtml-var error_tb>

Other variables that are defined for error messages are:

  error_message (may be null)

Take a look at /standard_error_message for their usage.

Subject: [Zope] Serving external files
Message-ID: <38E068A5.11CCAA4D@rrsg.ee.uct.ac.za>

Hi,
I have some questions about serving external files:

I want to be able to serve a file that is external to Zope's Object
database. This file would probably be a binary file. So far, I have an
external method that reads the data from the file, and sets the header
of the RESPONSE object passed to it. The external method looks something
like:
    def readFile(self, REQUEST, RESPONSE):
        ...
        data = f.read()   # where f is the binary file, and has been
opened
       RESPONSE.setHeader("Content-Type", "application/data")
        return data

The zope id of the external method is "getFile".

I have a dtml method that calls this external method, using
<dtml-var "getFile(REQUEST, RESPONSE)">
The id of this dtml method is "download".
Say I have a dtm document with something like
<a href="download">SomeFile.dat</a>

This works, and the file is downloaded correctly. I want to know firstly
whether there is a better way of achieving this.
Secondly, when the user clicks on the SomeFile.dat hyperlink, and the
browser's "save as" dialog pops up, the browser uses the id of the dtml
method "download" as the filename in the dialog. Obviously I would
rather this dialog shows the name of the file that will be downloaded.
How can I change this? I can't rename the dtml method suitable for each
different filname that might be downloaded, so where else can I alter
this behaviour?

Thanks
Allen

Take three. I've solved the problem for all cases by having the ZClass 
add method redirect to a method that copies the default methods into
the new ZClass instance, then redirects back to the management screen.

Might have to write a howto for this one.

<dtml-var ***> with an image object writes out a full <img
src=***>-tag..
Your html-will look like this :
background"<img src="myimage">"

write it out as straight html :
background=myimage"

the error you're getting is probably because of the faulty
qouting in the dtml-var-tag..

Message-ID: <v04205507b5061c302dc9@[130.227.115.56]>

Hi,

I have a simple question - how do I use the fmod function in the math 
module with dtml ?

I've tried something like this(and a lot of variants):

<dtml-if expr="_.math.fmod(x,y) == 0">
	do something
</dtml-if>



What is it for:

I have some words returned from a search which I want to be displayed 
like this:

word_a	word_b	word_c
word_d	word_e	word_f
word_g	word_h	word_i

Thanks in advance.

And with good reason, you have overlapping angle brackets, your expression should read

<body background="<dtml-var "myimage">"

or

<body background="<dtml-var myimage>">

but this won't achieve what you want. What you really want is:

<body background="&dtml.url-myimage;"> 

See http://www.zope.org/Members/AlexR/EntitySyntax for more details.

Try looking at the LocalFS product available on the Zope.org site.

It makes folders on the physical drive look like part of the ZODB.

You need to recompile your kernel with an higher value for MAXUSER parameter
(x2 or x4 the current value).

MAXUSER parameter helps the kernel handle the load of the machine(max file
numbers, buffers, etc...). Python&Zope opens loads of files on the
filesystem, so the default value for MAXUSER is not enough.

Hope that helps.

Hi

The following snippet (tested) works as expected, printing the values in
three columns.

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('WordList', ['word_a', 'word_b', 'word_c', 'word_d',
'word_e', 'word_f', 'word_g'])">

<dtml-in WordList>
  <dtml-unless sequence-start>
    <dtml-if "_.math.fmod(_['sequence-index'], 3) == 0">
      <br>
    </dtml-if>
  </dtml-unless>
  <dtml-var sequence-item>
</dtml-in>
<dtml-var standard_html_footer>

Yes. Use the LocalFS product, it's taken care of a lot of the things 
that you're battling with (I've done the same thing and am in the 
process of moving to LocalFS).

Again, LocalFS will do this for you (my main reason for switching!).

Subject: [Zope] Is Zope suitable?
Message-ID: <000001bf989a$f08d97a0$1e01a8c0@tingeling>

Hello!

I have some questions about Zope and I thought I ask them before
spending alot of time reading the documentation.


Can I install zope on a apache system WITHOUT being root? My ISP is
running apache on a Solaris 5.6 system.

I want to create a system that lets any user create his own User Data
Record. The user data record will contain data about the user, e.g.
Name, email address, etc. This record should only be editable by the
user (and admin) with somekind of login. This user data must then be
searchable! Listings on all or some of the data should be able to
present in different sorting orders, e.g. Lastname, country, etc.

Is Zope suited for this kind of system?
Maybe someone already has created a system like this?

   You can, but would your ISP allow you to run Long Running Process? Zope
is LRP, you know, and many ISPs are very afarid of it.
   In any case you'd nned a support from ISP to setup a way their WWW
server will use to talk to your Zope installation - pcgi-wrapper,
mod_pcgi2, ProxyPass...

We made something like this with zclasses and regular user
folders recently, using a zclass to hold the
info, and dynamically creating users with localroles in
their own zclass-instance, allowing them to edit their own
information..

Not the best way if you expect a lot of writes to your
server,i guess,  but nice enough for small sites..

Thanks -
I have downloaded LocalFS, but haven't tried anything substantial with it,
my reason being that I needed to upload these external files as well.
A user must be able to upload a file, which will be saved to the local file
system, and made available for download from the local file system. The
actual path to the file will be stored in a relational database (along with
a whole lot of other info). If I were to use the LocalFS product for this,
is it possible to add a LocalFS object dynamically (through some dtml method
that gets called when a user uploads a file)? Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.

Any comments appreciated!
thanks
Allen

Thanks, this works perfectly. I don't know why my code doesn't work 
because I have tried the same thing as you have. But I must have

Yes, but just set up a LocalFS object from the management interface 
and don't worry about it. If you're worried about files cluttering up 
the filestore, use a cron job to wipe them out.

Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.


It uses python filesystem methods, so I reckon the number of files in 
a LocalFS object (ie the directory) is os limited.

I sent an email to the list on the 21st March where I had some 
(rudimentary) dtml and python code that uploads to a LocalFS object 
(ie the directory that the LocalFS object is pointing to). Check it 
out, the subject line is [Zope] Re: [Zope-dev] RE: ZDiscussions

Message-ID: <REhvNZAilI44Ew7q@compkarori.com>

I couldn't see this covered in the Zsql user's guide.

select myfield from foo

works as expected.

As the current ODBC driver I am using has a bug which truncates varchar
fields, it was suggested I cast it to char while retrieving the field.

But

select cast(my_varchar_field as char(140)) from foo

gives an error with the following traceback...

I just found a HOWTO by jpenny: Accessing a ZSQL method from an 
external method. It helps a bit but actually I don't want to use a 
ZSQL method I just want to take advantage of a persistant connection. 
Wait, I got an idea ...

[20 min. later]
Hooray! Try this: I have an open ZMySQL Database called 
'my_connection'. Now I can query the db from my external method with:

self.my_connection._v_database_connection.query('select * from whatever')

[another 20 min. later]
I benchmarked it agains opening a connection and cursor and then 
execute() and fetchall(). Using the Zope connection took about 60% of 
the time the other method took.

I wonder if there are any disadvantages???

Synchronicity!  I've just read the same document today and found the python
code for database connections (in ./lib/python/Shared/DC/ZRDB/Connection.py,
if anyone is interested :-), and am about to try passing my own queries in.

> I wonder if there are any disadvantages???

The only one I could immediately think of was "what if the database
connection hasn't been opened".  I can see the method for
manage_open_connection() (and _v_connected/connected() for the status
of the connection), but don't feel 100% comfortable calling Zope
internals just yet.  Any caveats for just semi-blindly calling
.manage_open_connection() if .connected() returns false?

Subject: [Zope] Problems with ZCatalog-indexing
Message-ID: <Pine.GSO.3.96.1000328140758.20415A-100000@nausikaa>

Hello all,

I've got some problems with indexing in ZCatalog.

First of all it doesn't seem possible to index words containing any
non-ascii characters (most important german umlauts). On zope.org the
only info on charactersets I found was, that there are some supported
ones, but I couldn't find out which these are.

How is it possible to have a correct indexed catalog on a german site ?

The second problem is related with the first one, but not restricted to
german characters.
Words where a hyphen appears, e.g. names like 'Hans-Dietrich', aren't
indexed at all, in the example 'Hans-Dietrich'
cannot be found on the site, but 'Hans' or 'Dietrich' cannot be found,
either.

If I cannot fix these Problems, the ZCatalog is unusable in the site, as
there are a lot of important keywords using umlauts or containig hyphens.

Thanks for your help,

Tobias Kiesling

You should use a recursive mathod.

Write one method recursiveMethod:

def recursiveMethod(obj):
     result = []
     if obj.parent != None:
          result = recursiveMethod(obj)
     if obj.meta_type=='KBItem':
          result.append(obj.Title)
     return result

Then call this method like:

def GetParentNames(self):
     recursiveMethod(self)


This code is untested, but should work.

Stephan

I'm glad you found a workaround.  Just offhand, did you try to just call that
additional method, before redirecting to it?  I have seen a couple of cases
where I refactored code like that into a new method and then things got simpler.

We're phasing out hosting in favor of DASH (Dedicated Application Server

Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT for
some reason, there's an HP box available. For more details, see:

Hi,

I'm in the process of cleaning up our production Zope server and I've found a folder which has one
file in it. I don't know who created either of them and I'm wondering if they're redundant.

I'd like to find out who created the both the folder and the file and, if possible, when it was last
created. How do I go about doing this?

Cheers for any help,

Subject: [Zope] Newbie question - product embedding
Message-ID: <38E0C7B5.38276033@advis.cz>

Hello,

I am just evaluating the Zope system, and it looks good. I am trying to
build an example Intranet site, using Squishdot.
I need a poll embedded in one of the Squishboxes.

I tried both PMPPoll product and Poll product, but cannot get it to
render into the page.

I have a DTML method calling the poll object like this


... some simple HTML ...
<br>
<dtml-var name="my_sample_poll">
<br>
.. some more simple HTML ...

The simple HTML indeed appears in the box, but instead of the poll form,
which I expect to be rendered, I get the following in the page source :

<br>
<Survey instance at 8635589>
<br>

Am I missing something obvious? Should I call the object from within my
DTML method some other way? Thanks for your help.

Hi,

Yes, this gives me parents, but it doesn't work for my problem :

The external method is used for storing the information into a ZCatalog.
Now, when the Catalog is updated, I get the wrong parents, I get the
parents of the catalog and not of the object itself. :-(

Somebody another idea?

Tom.

I tend to agree with Tres here. MySQL can certainly handle BLOBS, but
here's something you might not realize: All MySQL queries are literals.
Let that sink in for a moment. What does this mean? Suppose you are
using MySQLdb (not a ZSQLDA, we'll get to that). You need to do
something like this:

c = db.cursor()
c.execute("INSERT INTO BlobCity (Pix) VALUES (%s)", pix)

Looks simple, doesn't it? Well, here's what happens behind the scenes.
First MySQLdb has to turn pix into a MySQL literal value. Fortunately, if
you have, say, a JPEG class, you can write a function (not method) which
converts it into a MySQL literal. Suppose your class has a __str__ method
which returns the raw data as a Python string (maybe it IS a string
internally). Then you can do:

def JPEG2Literal(j): return "'%s'" % MySQLdb.escape_string(str(j))

(Although this is actually the default converter, used for strings; if you
have a __str__ method, you can just pass it to MySQLdb and it should do
the right thing.)

MySQLdb.escape string does all of necssary escaping of special characters,
namely backslash, NUL, and single-quote. But to do this, it has to
allocate a temporary buffer that's twice the size of the original string
to handle the pathological cases. Then quotes have to be added. Then this
all has to be inserted back into the original query. In the case of a 5 MB
BLOB, these steps work out to be:

1) str(j): 5MB
2) escape_string(#1): intermediate 10MB, return new 5MB+ string
3) "'%s'" % #2: return new 5MB+ string, but del #2
4) querystring % (#3): return new 5MB+ string, but del #3

So you're making and destroying a lot of big strings, which takes a
considerable amount of time. And we're only using one column and one row.
(I should probably make a new C function that combines #2 and #3 for
efficiency.) Most of what MySQLdb does is string crunching. For that
matter, MySQL returns all values to the C API as strings (including
numbers).

And now the Zope ZMySQLDA case: Z DA's always build literal queries
anyway, so this makes MySQL no worse off than any other database. (Most
database APIs, like ODBC, seem to use positional placeholders in the query
and pass the rows/columns as a data structure, which makes for much less
parsing on the server side, and is much easier to construct on the client
side.)

Compare this to writing into the filesystem. Well, no comparison, really.
open, write, done. So long as you can keep things organized, you're ok.

I'm guessing I could do it with MySQL...  what does everyone think?  
Is there a Zope plugin that already does this.  
Does someone have some code laying around you could send me?

MySQLdb is not a Zope Product; it's a Python module. ZMySQLDA is the Zope
Product. It needs to be patched to work with MySQLdb, however. I have no
idea how you would do this on Windows. Only the Python code (no C code)
needs to be patched. Stay tuned...

Message-ID: <3.0.6.32.20000328181014.0092e0c0@poirot>

Ok, now I found the error. The error must be in the while loop, where we
say 'iterate until the obj = None'. However 'None' is never reached... (I
guess). 
The following code works, but I this isn't at all a good solution. 

Can someone tell me how I can safely test that the current object is the
first object in the object database. In other laguages you can test this
with 'nil'. How can I test this within Zope? Please, tell me!

def GetParentNames(self):
  result=[]
  obj=self
  while obj.title != 'Zope':
    obj=obj.aq_parent
    if obj.meta_type=='KBItem':
      result.append(obj.Title)    
  return result

Thanks in advance,

Tom.

You must your locale environment variable correctly.  See 'man locale'
on linux, for example.  Also, you can pass z2.py the -L argument to
explicitly set a locale.  This will allow you to index german
characters.

Hyphens are hard coded in the text index to split words.  This is
because the text splitter is not very flexible and is very english
centric.

To fix this, you must either 1) create your own splitter, 2) update to
the latest CVS and create your own vocabulary and provide a new
splitter.  

The CVS version of Catalog is much more language neutral, and there are
now two kids of vocabulary object, English and Globbing-English.  Soon
someone I'm in contact with will be providing a Japanese vocabulary.  If
you have the patience, you should developer a German vocabulary to
address these issue.

Sometime between when your catalog was generated and when you tried to
re index the content you updated your CVS sandbox.  When you did this,
you got the new catalog code that doesn't work with old catalogs.

This non-backwards compatability has since been fixed.  If you update
your CVS to the most recent version this error should go away.

Let me know if it doesn't.

I think this would be a useful addition to the Zope core...I find
myself doing the same thing and I've been thinking about developing
the generic add form but haven't had time to even start it.

This works for me:

<dtml-with right_poll>
  <dtml-var index_html>
</dtml-with>

Of course you'll have to modify the poll's index_html document to
remove all of the full page stuff because you only want a table cell
for rightbox items.

Hi!

First of all I've to say that I'm a realy beginner in Zope.
I recently updated from 2.1.3 to 2.1.6 and noticed following problems:


In 2.1.3
<dtml-with "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
  <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
  </dtml-in>
</dtml-with>
 works great

In 2.1.6 it produces an Error message that
title, empf_sem, diplompruefungsfach is not known by the system
(I already Posted that)

Now I found out that
<dtml-call "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
 <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"_.getitem(REQUEST['fach'],1).propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
 </dtml-in>

works fine in 2.1.6. (getSubjectInfo is a SQL Method)

Has someone a hint for me?

Helmut.

Subject: [Zope] RE: ZCatalog Indexing
Message-ID: <38E0EC1E.7DBC7011@hiretechs.com>

Tobias,

The Catalgo uses a stripper to make the indexes smaller. It doesn't
index =-+*&)(^%$#@. etc... or numbers.  Some words too like 'Bill'. From
what I've been told there is a version of the Catalog on it's way which
will allow you to put keywords or charaters in a special place that will
include them.  I couldn't wait for that, and I love Zope, so I came up
with a major kludge.  catalog_quote() and catalog_unquote().  They are
from an External Method which I wrote catalog_quote.py.  Here it is:


from string import strip, split, join, uppercase, lowercase, find
bad_characters=(('.'),
                ('+'),
                ('-'),
                (';'),
                (':'),
                ('&'),
                ('*'),
                ('%'),
                ('#'),
                ('@'),
                ('$'),
                ('0'),
                ('1'),
                ('2'),
                ('3'),
                ('4'),
                ('5'),
                ('6'),
                ('7'),
                ('8'),
                ('9'))

def catalog_quote(self, ascii):
    text = str(ascii)
    for re in bad_characters:
        if find(text, re) >= 0: text=join(split(text,re),ordinalize(re))
    return text

def ordinalize(letter):
    number = ord(letter)
    number_string = str(number)
    myletters = lowercase[-5:] + uppercase[-10:]
    converted = ''
    for character in number_string:
        converted = converted + myletters[int(character)]
    return converted  + 'g'

def catalog_unquote(self, ascii):
    text = str(ascii)
    for un in bad_characters:
        if find(text, ordinalize(un)) >= 0:
text=join(split(text,ordinalize(un)),un)
    return text


I just use it to turn anything that might contain the charaters in
bad_charaters into catalogable stuff.

Then when you search, you must catalog_quote() your search strings, and
you'll get 100% accurate results.  Hope this helps.


All my best,

Message-ID: <3.0.5.32.20000329041128.009adc20@mail.skinnyhippo.com>

I had a ZClass (InnerClass) which was defined within
another ZClass (OuterClass) as follows :

/Control_Panel/Products/MyProduct/OuterClass/InnerClass

And a great many instances were defined with both
the OuterClass and the InnerClass. However, in order
to catalog the InnerClass (it is not CatalogAware 
and I do not want it to be), I need to move it to

/Control_Panel/Products/MyProduct/InnerClass

in order for 'InnerClass' to appear in the select
list ('Find objects of type') under the 'Find items
to ZCatalog' tab of the ZCatalog.

So far, so good. I moved the class and now can 
catalog it. However, now the icon is broken on all
of the instances of the 'InnerClass' ZClass. I 
have tried adding a new icon under the 'basic'
tab of the ZClass definition, but that doesn't
help either. I know it's just a petty icon and
it doesn't affect functionality but I'd really
like to clean this up so any clues/help appreciated.

Thank you very much,

chas

Hi all,

This code results in a error:

<dtml-let MyVar="_.string.replace(Mytext,'"','&quot;')">

I know its because of the quote in '"' because that cause in
same way an error when the "dtml parser" is parsing the code.

I've tryed to use '\"' and even _.chr(34) instead of " but the former gives 
me the same error and the latter dont give a error but also
dont do the string replace I want to do.

Any help?
Thanx,
Julio

This one goes especialy to ho write zope.

I have found that the dtml-in has a problem when you specify a batch-size that is less than the double of the length of the input list.
Ex.:
a list of 6 itens:
when size is 3, dtml-in returns 3 itens, correct. (3*2 <= 6) = true
when size is 4, dtml-in returns 6 itens, error. (4*2 <= 6) = false

Is this a bug?

Adding an "orphan=0" tag inside the dtml-in should do it:

  <dtml-in foo orphan=0>
    . . . bar . . .
  </dtml-in>

A more general question for the list, though:  Shouldn't the default
orphan value be zero?  It seems to me that if someone explicitly says
"I want three items," it should be more of a special case that they'd
somehow want more . . .

Opps. It works, but my sugestion of using _.chr(34) also works.
I was looking at the wrong results when testing _.chr().

Tried that - I in-lined it on the list for brevity's sake. The problem
is definitely with manage_clone not wanting to be used on a thing
inside the transaction that creates that thing.

Message-ID: <71D21CF19DE2D011AD43006097BD8C019D5C7B@SJMR-MSG-01>

Sometimes when I reference other dtml documents I get the dtml code returned
as text,  rather that outputting HTML like it should.  For example,  the
code I have below will print out the standard header properly and then
display the raw html where the Eligibility.MemberInfo document should be.
What am I doing wrong?

<dtml-var standard_html_header>
<dtml-in SQL_ViewMember>
 <dtml-var "Eligibility.MemberInfo">
</dtml-in>
<dtml-var standard_html_footer>

Hi there,
This must be simple, but I haven't found it in the docs.
Can I get ZopeTime to give me the date, say, 20 days ago ?
Or a month ago ?
Something like (yes I know this won't work) 
<dtml-var expr="ZopeTime - 20")

One thing you need to keep in mind is that dtml-in has an orphan
attribute that determines the minimum amount of items to print out.  If
orphan is set to 3 (default) and you have a list of 6 items, and you set
size=4, the dtml-in tag will realize that 2 is too little to have on one
page and so it displays all 6.

If you don't want this, set orphan=0 in the dtml-in.

Subject: [Zope] BASE tag on File objects
Message-ID: <m38zz23a9e.fsf@wacko.pdx.net>

I've got a number of static HTML files on my site that Zope keeps
putting BASE tags into.  IMHO, it is inadvertantly appending a slash
onto the end of the HREF.  For example a file called default.htm in
the classified directory ends up with a base tag of:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm/">

I would think this should be:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm">

So I have modified: OFS.Image.File.index_html to strip the trailing
slash by adding:
        # clean up the base if neccessary
        if( RESPONSE.base[-1:] == '/' ):
            RESPONSE.base = RESPONSE.base[:-1]

What think you?

-Jon

This should work:

<dtml-in SQL_ViewMember>
  <dtml-with Eligibility>
    <dtml-var MemberInfo>
  </dtml-with>
</dtml-in>

There could be a way with zserver but I don't know it. My advice is to
use PCGI for performance and salability anyway, though. ZServer is
quicker to setup, but in a production environment, apache is still
higher performance.

Although, having CGI scripts are never good for performance. ;) PCGI
is fine though.

You can generally have both pcgi and zserver installed without a
conflict; there's just no point to it. There very well could be a way
to "wrap" CGI scripts in zserver, but it would still be better done
in a true apache environment, where it belongs. To be 100% ZOPE you
would re-implement everything in Zope/Python/DTML though. I've seen
a lot of company areas where zope stuff points to CGI stuff and visa
versa, so your situation seems to frequently be solved that way.

You only need Zope-pcgi if the cgi calls need to come off of the
same IP as the rest of your zope.  If your Zope site is, say,
www.mysite.com, then you could put your image cgi stuff into an
Apahce responding to the an IP under the name of, say, images.mysite.com.
This would be your maximum performance route: direct calls to
Zserver for the Zope stuff, and direct calls to Apache for the cgi
images.

You only need the separate IP, by the way, if both need to be listening
on port 80 (say because people from behind a firewall need to access
your site).  If you can deal with either one listening on another
port, then Zope at least can deal with that (I imagine Apache can too,
but I've never tried it.)

> If this is the case, I will need to uninstall the Zope-Zserver (if I try
> to have both, there is a conflict) and install Zope-pcgi.  Does this mean 

What have you run into that makes you think there is a conflict?
When you run Zope using pcgi, you are still running Zserver.  It's
just listening to pcgi calls instead of port 80 (or whatever) calls.
It is certainly possible to run Zserver such that it will respond
both to direct calls and to pcgi calls.  This is the way it is set
up by default, at least under Unix if you compile Zope using
w_pcgi: Zserver listens on port 8080 for http traffic, and also
communicates with Apache using pcgi.

Reinstalling to add pcgi support is like upgrading to a new version
of Zope: copy your var directory (actually just Data.fs should be
enough) to a safe place, do the install, and then copy your saved
var overtop of the new one built by the install.  You'll also need
to reinstall any Products that you downloaded and installed.

Hi,

I am looking for a translation engine (similar to Babelfish) that can 
be fully integrated with Zope. The only option I found so far is 
GPLTrans, which is based on PHP. Before I start porting it to Zope: 
is there anyone else out there already working on a similar project?

Anyone interested in helping out with such a project? Have a look at

   http://babelfish.altavista.com/
   http://gpltrans.sourceforge.net/

to see what I am talking about. Results to be released under the GPL.

Thnx,
Jonathan

Hi,
How do I import a module - I've been reading the DTML guide, and I would
like to use some of the functions described in the string module, but
how do use them - do I have to import the module (if so, how), or what
else. What I want to use is the following:
<dtml-if expr="lower(somestring)=='supplier'">

</dtml-if>
where lower is defined in the string module. I've also tried
string.lower(...) but that didn't seem to work.

thanks

I don't think you'd need any Zope products or additional code for a basic
implementation of what you want to do.

Just create the folder structure you want to have in Zope. Then you can add all
your documents with the management interface. To create the directory view, you
only need an index_html DTML Document that lists the folder structure (either
using the tree-tag or some dtml-in construction). 

For higher performance, you can use the ZCatalog to index the folder structure
and use code similar to the one on Zope.org to list the topic pages (e.g. all
the news on the Zope.org news page and all the products in the download area
are collected from the site using the ZCatalog.

I wouldn' use MySQL for that particular task because it fits the ZODB (Zope
object Database) perfectly (many reads, few writes).

You could also look into some of the products on the download page. I recall
that there might be some "out-of-the-box" directory solutions.

I'm finding myself again trying to figure out how things work in Zope, just
to find out at the end that it is MUCH simpler that I thought  -- but totally
undocumented! Or maybe I just haven't looked for it enough ...

Isn't there somewhere a list of all method calls I can use from DTML (like
manage_addXYZ)? It can't all be just trial and error or "read the code". -- Yes
it can, but I don't want to be that pessimistic ;-)

O.k., my current problem is that I have a folder with icons and images in a
ZClass that should be copied to all new instances of the class.

There seems to be a "manage_clone" call for that (just read about it in a
posting), but how does it work and where do I find any documentation on it?

As all those methods are in the namespace, isn't there at least a trick to get
a list of all names to print out? That would be a first start.

I mean, I had to figure out every single call like manage_addDTMLDocument or
manage_changeProperties by trial and error. That makes Zope so much less
efficient that it could be ...

The string module is already available, just not as you'd expect ;)

Try something like:

<dtml-if expr="_.string.lower(somestring)=='supplier'">

</dtml-if>

You could also try <dtml-var "Eligibility.MemberInfo()"> although this might to use the namespace

from the zqr: 

manage_clone(ob, id, [REQUEST])
           Clone an object, creating a new object with the given id.

have you tried :

<dtml-var "Eligibility.MemberInfo(_.None,_)">

- just might do what you want..

Don't ask me about the specifics of what  (_.None,_) does,
though.

Subject: [Zope] passing arguments from dtml methods to SQL methods
Message-ID: <38E1D121.D5689279@rrsg.ee.uct.ac.za>

Hi,
Thanks for previous help on the namespace variable '_', much
appreciated!

I have another problem though, how does one pass parameters between DTML
methods, and from dtml methods to ZSQL methods?

I have a DTML method "getSearchResults" that gets called when a form is
posted using
<FORM... action="getSearchResults">
<INPUT NAME="fname"
</FORM>
The method gets called and magically the form fields like fname
described in the above form are accessible from the dtml method, so I
can do <dtml-var fname> and there's the input from the user. (I still
don't fully understand how that bit of black magic works...)

Ok, then I have a ZSQL method with fname as an argument, and again, when
my dtml method calls the zsql method, that variable fname can be
accessed using <dtml-var fname> in the SQL query. While maybe I don't
completely understand what's happening, I can still use it. The problem
now is, my ZSQL method needs to have an argument "tablename" that it can
use so that a different table can be selected, however, this tablename
is not under the user's direct control. It gets set according to some
choices that the user makes along the way. I would hence need to
"declare" it in the dtml method "getSearchResults", initialise it, and
pass it to the ZSQL method so that the ZSQL method can use it. I tried
doing the following: (suppose the ZMYSQL method's id is "searchMySQL").
in the dtml method:
    <dtml-if expr="whatever">
       <dtml-var name="getSearchResults(fname=fname,
tablename='suppname')">
    </dtml-if>
So that didn't work, but maybe it describes what I'm trying to do - that
is, fname exists and is initialised from the user's form input, but
I want to create the variable tablename, and pass it to another method
(or just create in the namespace space so that it's accessible to other
methods).

Sorry to be so long-winded, trying my best to describe things with my
very limited knowledge of zope/python.

Many thanks
Allen

Hm, is it - if it's undefined? 

what about (taking the function from one of your previouw posts) (only
lightly tested):

def recursiveMethod(self, obj, result):
    try:
     if obj.aq_parent:
           result.append(obj.title)
           recursiveMethod(self, obj.aq_parent, result)
    except AttributeError:
        pass
    return result

This is less elegant than testing for the attribute aq_parent, but
either hasattr is not allowed for External Methods, or ac_parent is not
an attribute.

Note, however, that if an object has no title it may also throw in an
AttributeError, thus aborting your method in too early. You could try
and catch this exception separately, but perhaps it shouldn't happen
anyway.

One small addition: I threw out the test for KBItem (because my Zope has
no such items), you can put them back in at line 4. Sorry for posting

Try using a COUNT in your SQL select formula. 

e.g.

Select count(colname) from tablename where colname='myvalue';

If it returns a 0 then that value doesn't exist.
If it returns anything then that is the number of times the value exists.

How about

<dtml-in "sqlFindItem(item=itemid)">
  <dtml-if sequence-start>
     do insert
  </dtml-if sequence-start>
<dtml-else>
     do update

Is it possible for zope to separate control from data automatically?

To make the best use of Zope, it will be necessary to separate the data and
control.

with XML, DOM will assign id for each node and thus  all of them can be
refered by that id.

Is it possible for zope to perform this? Will a modify of  load_site able to
do this semi-automatically? (run load_site over an existing zope tree?)

Message-ID: <Pine.LNX.4.10.10003291331390.19425-100000@oeh.tu-graz.ac.at>

if you want to pass variables to a dtml method you have the option to
set it in the REQUEST object eg.

  <dtml-call "REQUEST.set('varname', 'somestringval')">

or put it in the namespace eg.

  <dtml-let varname="'somestringval'">

then call your method as per normal eg. <dtml-var yourmethod> which
then will find the vars you set before.

or you call your method with keyword args like

  <dtml-var "yourmethod(_.None, _, varname='somestringval')">


note the difference between 

  <dtml-var "method"> which is <dtml-var expr="method">

and 

  <dtml-var method> which is <dtml-var name="method">


see the "Document Template Markup Language Reference",
http://www.zope.org/Documentation/Guides/DTML and the zope howto's.

Salutations,

I've been staring at this one for a while, but I can't quite seem to
pull it off.

I'd like to render a document based on the contents of a variable.
For example (simplified):

<dtml-call "REQUEST.set('foo', 'index_html')">
<dtml-var foo>

should (would? could?  I'd like!) render index_html.  Double
quotes don't cut it (both print the string 'index_html') :-(

- Because PrincipiaSearchSource (which is probably what you
are using for your full text search) is a property(method?) of DTML document and
method, but not of your new product..

try making a pythonmethod or external method (pythonmethod
is simpler) inside your
Zclass containing something like :

   return string.join((self.yourAttribute1, self.yourAttribute2, self.yourAttribute3), '; ')


where yourAttributeX are the attributes of your Zclass..add
as many you like...

name it PrincipiaSearchSource if that's what you're using
for the full text search.. (might be 'raw' too...)

Hi,
Thanks again for the help with the let and with tags...

I am making slow progress, but now can't seem to display my results from
a ZSQL method. How are the results returned? If they are in some
RESPONSE object, how would I read the items out?
So far, I have an SQL query which I'm fairly sure is working, and whcih
when tested gives the results I expect, but when I use it in the
following bit of DTML, nothing is rendered at all:

<dtml-call "REQUEST.set('cmatch', 'sup_name')">
<dtml-var searchMySQL>

The <dtml-var searchMySQL> line returns nothing, even though I know that
there are results for that method.

Apologies if I'm missing something I should be picking up from searching
the archives, but at the moment our connection is bogged down with lunch
time traffic, so I can't even get to the zope site.
thanks
Allen

No biggy..

<dtml-in searchMySql start=query_start>

<dtml-var variable_name>

</dtml-in>

That should get  you started but you should read the ZSQL Guide as it 
has lots of options that you can include (size, orphan, start 
sequence, end sequence, etc)

Really is worth the read.

Bear in mind you may have two pythons running on your machine.. the 'normal'
python that appears when you type 'python' at the command line, as well as
the python that zope installs. It may be that PIL is only in the path of the
former and not the latter.

In my case, 'foo' must be a string, and is actually passed in via
a POST (I need it to maintain state in a "wizard" style form).

Subject: [Zope] ZRDB
Message-ID: <38E22874.727DD231@wildenhain.de>

Hi,

browsing thru Shared.DC.ZRDB.Results i found this construct:

-------- line 117 ------------
		if not name:
			raise ValueError, 'Empty column name, %s' % name

------------------------------

This looks a bit silly, because if name is empty, %s will be replaced
with
nothing...
Furthermore, would it not be better to provide a generic name for the
empty column? Sure, it is difficult to provide such a name who does not
collide with others in namespace, but it would be very helpful, if the
underlying database-adaptor does not provide full names under certain
circumstances, such as ODBC with CenturaSQLBase always returns
empty column names to Zope with the count() Operator. Even if used "as"
to rename.
How about something like:
		if not name:
			name='column%d' % i

or such?
Next there is always some hassle with those 'table.column' columns
returning from databases who do not support column renaming.

Would it be a way to rename them automatically to something like
table_column? Yes, I know there could be a column already beeing 
called so. But if one knows she can use table.table_column in such
circumstances.
May be as alias?

I'm coming in late on this thread, so ignore me if this 
has already been covered... :)

It sounds like what you want is something like the following:

# docname is the variable passed in via the POST whose
# value is the name of the document to render. We use
# _.getattr(this(), docname) to retrieve the needed 
# document from the current object. Note that we use
# the "let" tag instead of REQUEST.set, which is 
# increasingly considered evil :)

<dtml-let theDoc="_.getattr(this(), docname)">
  <dtml-var theDoc>
</dtml-let>

Subject: [Zope] Problem with SQL+Special chars...
Message-ID: <B507F9A6.5E85%owrede@khm.de>

I am having a problem with HTML entities.

I am using Zope to enter and output text into a MySQL Database.

When I output the text, it is rendered through my own External Method:

   <dtml-var "myMthod(myText)">

I tired to write a little subrouting which is supposed to translate special
chars in the database into HTML during output.

Unfortuneatly the texts are entered on both MacOS and Windows browsers. This
unfortunatly makes it difficult: There is no unique ASCII code in the
database -- in other words: the same special char may be represented in the
database with to character values.

First I looked if the <dtml-sqlvar ...> had anything to offer, but that does
not seem to be the case.

How can I store text in ISO-Latin into the database regardless the Text is
entered via a Mac-Browser or a Windows-Browser?

Message-ID: <38E22FB4.7C8FFF18@nipltd.com>

Can you do colour in structured text?

The reason I ask is that I've just found out how great ZWiki Webs are but I'm wondering if there's a
shorter way of changing text colour than:
<FONT COLOR="#xxxxxx"> </FONT>

I'm looking to use a Wiki so a group of people can edit a web of documents and I was hoping that
each person could use a different colour. Having to do the colour by hand defeats the simplicity of
a Wiki :(

Any ideas?

Subject: [Zope] Mac2ISO conversion?
Message-ID: <B507FECC.5E86%owrede@khm.de>

I need to enter text data into a MySQL database via HTML forms.

Text entered on a Macintosh client is not ISO-Latin as it seems. When
getting that text out of the database, the special characters are broken in
the HTML page but not in the textarea.

Text entered via a Windows browser are not broken in the Mac browsers HTML
page - but in the textarea.

So I guess I should care for getting ISO-Latin text from the Mac clients
into the database!

From other areas I know this requires a mac-to-iso translation (in both
directions (because the text must be editable on Macs).


But how can I do this in Zope?

I know how to figure out, if it's a Mac-Client -- do I have to create an
External method fr this?

Hi,

I'm doing a back link to go on a page (yes, I know browsers have back buttons, but some people don't
like to use them ;-) which is easy enough:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>

except that if there is no referer, you get a key error. So I thought I'd try the following:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>">Back</A>

But I still get a key error. I thought the 'missing' attribute was supposed to catch that?

   Not quite. You are tripping a key error here so that won't work. Try:

<dtml-if "REQUEST.has_key('HTTP_REFERER')">
   <dtml-var "REQUEST['HTTP_REFERER']">
</dtml-if>

It still exists, in a very domant stage.  The next Zope release will
probably break it right out.  There's not much you can do with ZTables

Subject: [Zope] building/exporting site and server question
Message-ID: <4.2.2.20000329111442.00a63b10@mail.bowmansystems.com>

I am relatively new to Zope, and I am working on a personal project at home 
on my Win98 box. I am just now getting the "zen" of Zope as everyone refers 
to it, and am building a true functional application.

So now that I am getting comfortable with Zope, here is my question. I am 
wondering if I can build my site/application on my Win98 box at home, 
export it out and then import it into another Zope installation running on 
another operating system (either BSDI or Linux). I am thinking I will have 
to buy my own server so that I can let Zope run as the server itself -- our 
servers up here all run Apache and I doubt our systems administrator up 
here would want to take the time and effort required to get that running 
properly (plus those are production servers, not really for employee 
projects!).

Is it possible and/or recommended to build a site/application on one 
installation and import it into another? Or should I just go ahead and by a 
box, put Linux on it, and proceed to build it on that platform? My concern 
is spending a lot of time building out the site on my home box and then 
finding a show-stopping hitch in the migration to another 
platform/installation.

Anyone who has had any experience with migrating Zope applications to other 
platforms/installation please reply so that I can make an informed decision 
as to how to proceed.

And also is there any reason to use Apache instead of letting Zope run as 
the server itself -- this will be on my own server so I doubt there will be 
much else on the box then my personal project and my home site (two virtual 
domains).

Thanks in advance.

This counts only for something like <dtml-var ought_to_be_missing
missing>
In your case you are inside Python when calling with " ".
So "missing" cannot catch this exception.
(Actually this simple <dtml-var .. > does much magic :)
So in your case you should do:

<dtml-if "REQUEST.environ.has_key('HTTP_REFERER')">
	<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>
</dtml-if>

This has the advantage of no blind link if there is no HTTP_REFERER set.

The reasons I came across were if you wanted to use SSL or have a site that
is half Zope, half Apache. Otherwise for simplicity sake ZServer by itself
is a great option. It is certainly the fastest and easiest to set up.

I decided to swith the roles, as I have ZServer running on Port 80 and
Apache on 8080 to sever up statistics, documentation docs and other very
static and non-production things that would be difficult to get into Zope.

As for the W98 migration, I would say develop it on the box you are going to
use it on. In the long run all the experience you get on the development
will not transfer to another OS. Linux is a great way go.

Btw. this works:

<dtml-with REQUEST>
  <dtml-with environ>
    <dtml-var HTTP_REFERER missing>
  </dtml-with>
</dtml-with>

or 

<dtml-with "REQUEST.environ">
    <dtml-var HTTP_REFERER missing>
</dtml-with>

if you want :-)

If you are experimenting with WIN 2000 try creating a NETWORK MAPPING
(WEBDAV) to a ZOPE FOLDER.

1. Click on Network
2. Click on Add a Network Place
3. Enter the url to a ZOPE Folder
4. Done

You now should have a folder view in Windows that Maps to a Zope Folder.
Enabling all sorts of great things:

1. Editing and Saving back to the folder with Security
2. Drag and Drop assets into the folder with Security

Great work on the Implementation of WEBDAV!!! Thanks DC!!!

That's very good news! Unfortunately I haven't been able to 
install win2K yet to see how it worked - I know about one 
further tweak that a little microsoft birdie told me I could
use to enable editing of "unprocessed" source (i.e. double 
click on a DTML method from a web folder and have it open 
unrendered in your chosen text editor or something). It 
shouldn't be hard to add, I just need to get the time and find
a box that I care little enough about to put w2K on it... :)

They do not offer "normal" PHP as an option -- you could ask them if they would
quote it as a "custom" add-on.  With enough work, it might be possible to call
PHP through a Zope product;  I don't know enough about what support PHP requires
from the OS and environment to know if this is feasible.

Of course, I also can't think of any reason to use PHP, but that is another
issue altogether. :)

The render-method collects items from a catalog and calls these objects'
"render" method.
Unfortunately this raises an Unauthorised Error, whenever I do not use the
super-user account.
(Zope has encountered an error while publishing this resource. 

Unauthorized

You are not authorized to access render.

Ok, so I gave the calling Method the proxy-role of the Manager. No change.
The strange thing about it is, and that is what puzzles me, that it works
for another class (which does only slightly different things).

So, what now, hu?

Regards, Ingo.

Do you mean site usage statistics (page views, etc.)?

If so, how do you measure Zope's stats if it is running as a separate
server and logging separately?

ZServer runs at Port 80 and logs all of its activity to Z2.log. I have
Apache running on port 8080 and it is logging to its own access log. I run
Analog (and Webalizer) on the Z2.log (cron) and write it to the Apache HTML
directory. That way I can browse all the Zope stats I want while not having
to import the static HTML into Zope. This also works great for documentation
and other things that come as static HTML.

The site, though, is pure Zserver.

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the zope-announce mailing list and
    the Zope.org site.

    The ZWN is changing days!  The next ZWN will be published on
    Tuesday.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * ZEO will go Open Source

    ZEO, the commercial Zope scalability option from Digital
    Creations, will go Open Source. After a trial period in mid-April,
    it will be available to everyone by mid-May.

    ZEO (Zope Enterprise Option) turns Zope into a distributed
    transactional object system, allowing people to add processors,
    machines, and networks to scale their web applications.

    More information can be found on the ZEO Product page.

    http://www.zope.org/Products/ZEO/

  * Oracle 8i Setup file, by Chris Petrilli

    Chris has released his Oracle setup file.  This file is used to
    create the Oracle library.  It has been tested internally for a
    couple of weeks.  See Chris's announcement for a caveat.

    http://www.zope.org/Members/petrilli/Oracle8i

  * Zope LATEX Math, by Bruno Vernier

    On his site, Bruno describes how to use LaTeX notation to render
    mathematical expressions directly from Zope.

    http://ess.vancouver.bc.ca/zope/math

  * Users Group - Ohio

    James Orbin <jorbin33@hotmail.com> would like to set up (or would
    like to participate in) a Zope users group for Ohio.  If you are
    interested, please write James, or see:

New Products

  * Software Product: L10NFolder, by "fog"

    The author writes, "This is a subclass of the standard folder with
    some added bonuses. The L10NFolder support localized properties
    and search paths."

    http://www.zope.org/Members/fog/l10nfolder


Updates

  * Software Product: XML Document, by Amos Latteier

    XML Document has been updated to work with Zope 2.1.6.  The latest
    release is 1.0a6.

    http://www.zope.org/Products/XMLDocument

  * Software Product: Zope MySQL Database Adapter, by "mordred"

    "mordred" has released an update to the MySQL Database Adapter, by
    Michel Pelletier (Portland). This release is 1.1.4, and fixes one
    bug:

      - Fixed a bug that caused Zope to fail on selecting aggregate
      functions such as 'select max(number) from table'

  * Software Product: ZWiki, by "simon"

    ZWiki is a Wiki web for Zope.  Zope and Wiki are a good
    combination.  Wiki assumes that, in general, users are
    trustworthy.  Zope, with it's security and transaction history,
    makes it easy to trust users.

    ZWiki is a sort of anarchic collaborative authoring system.  This
    version, 0.5, streamlines the default pages and UI, and disables
    the experimental catalog support. This release is intended to be
    immediately usable out of the box.

Zope.org items

  * How-To: Changing Base Classes for a ZClass, by "AlexR"

    When you create a ZClass, you are given an opportunity to chose
    which classes it will inherit from.  Since ZClasses are often used
    for rapid prototyping, you will not always select the correct
    classes the first time.  It is quite a lot of work to create a new
    set of classes with the correct bases and to move all the contents
    into them from the old classes.  Armed with this How-To, you will
    be able to change the base classes of a ZClass in-place!

    http://www.zope.org/Members/AlexR/ChangingBaseClasses

  * How-To: Serve PHP/Perl within Zope, by "Mamey"

    "As you migrate your site to Zope, you may want to embed a
    previously created PHP or Perl directory tree within Zope. Or
    perhaps you found a nifty web application that is coded in
    PHP/Perl and want to serve it within your Zope site."  This is a
    bit more advanced than simply rewriting certain URLs to be served
    by a different server.  This How-To will actually allow you to
    embed the external content in dynamic Zope pages.

Thanks so much everyone for all the help...actually, I ended up still
being able to use Zserver (without pcgi)...I left  the cgi programs on my
separate non-Zope site...and then for the image source, I just used a link
to the site, with all the corresponding parameters to generate the
picture...like so:

<img src="http://www.mynonzopesite.com/cgiprogram?parameters">

This worked! So, I was able to keep the regular Zserver, and still do
calls (at least for an image generation) to a cgi program residing on a
completely different site...looks like I will stick with Zope now, since I
am able to do this. :-)

> What have you run into that makes you think there is a conflict?

When I would do "rpm -Uvh Zope-pcgi-2.1.4-1.i386.rpm"

I would get the following message:

"error: failed dependencies:
        Zope-zserver conflicts with Zope-pcgi-2.1.4-1
        Zope-pcgi conflicts with Zope-zserver-2.1.2-3"   

But I no longer need pcgi, so I guess this isn't a problem for me anymore.

Thanks Again,
Jessica

Nope ...

I installed Zope-2.1.4-linux2-x86 and worldpilot-release-1.0.4.tar from
the zope-topdir. It installs correctly in ~/lib/python/Products/WorldPilot,
but when restarting the server, there is no "WorldPilot" or something
similar in "Available Objects" ...

I did:

umask 000
mkdir /var/spool/worldpilot
mkdir /var/spool/worldpilot/storage
mkdir /var/spool/worldpilot/storage/user
mkdir /var/spool/worldpilot/sessions
mkdir /var/spool/worldpilot/user
chmod -R 700 /var/spool/worldpilot

I set "DOMAIN.py" to domain="math.uni-bonn.de"

I converted those ^M (meaning

not show up in the available objects	;-(

Still, those DOS-format may be part of the problem?!?!

Confused ...

User-defined role authenticationAdam,

Something before I answer your question.

Please don't send HTML formatted mail to mailing lists.

Not all members use clients capable of reading it correctly, it makes it v
difficult to decipher when using elm for example.

OK that said onto the question.

You need to create users that have that role and then set permissions
appropriately for the location in question.

For example try turning view permissions off for the location. then try
browsing to it.

I have defined a role, editor, in my Zope system. It is not clear to me how
to prompt a user who is not a manager to authenticate so that Zope will
recognize the user as something other than anonymous. Any pointers?

Help very desperate....


We have a Zope site running: 
	Zope version: Zope 2.0.1 (source release, python 1.5.1, linux2)
		(also happens on a seperate box running Zope 2.1.6) 
     	Python version: 1.5.2 (#6, Sep 22 1999, 10:32:58) [GCC 2.8.1] 
     	System Platform: sunos5, Ultra-2  

It seems that if a user hits a page that either does an intense database
query or iterates over a large number of items, all other users are
prevented from accessing any page....! This problem may to be related to
the dtml-in but we are not sure.

For example suppose user A hits the following page (before user B hits
his page):
<!--#var standard_html_header-->
<dtml-in "_.range(999)">
	<dtml-var "_['sequence-item']">
	<dtml-in "_.range(999)">
		<dtml-var "_['sequence-item']">
	</dtml-in>
</dtml-in>
<!--#var standard_html_footer-->

And User B tries to access this page:
<html><head>
</head>
<body>
This is test
</body>
</html>

User B is prevented from accessing his page until User A's page returns.

Please help ASAP

I'm not sure I understand this. Perhaps you could rephrase the question.

We're phasing out hosting in favor of DASH (Dedicated Application Server
Hosting). This is not a price quote: For about $200/mo, you can get a
Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT

The RaQ3 is a Intel-like setup (AMD K6-2, I think). Earlier models used an
embedded MIPS CPU. I have no personal experience with either, but we use a
fair number of them (and some older RaQ models). Zope ought to run just
fine on it, but I've never tried.

I'm doing some Zope development on a VA 500 (dual P-II-350), and we have
two of them for mailservers. No complaints. They come with Red Hat. Using
my own RPMs for now.

Of course, the *other* one needs to allow one to write to the own

Message-ID: <Pine.LNX.4.10.10003291624590.20418-100000@kenny.comstar.net>

Environment: Red Hat Linux/Intel, Zope 2.1.6, GenericUserFolder 1.1.0

Problem: I have a GenericUserFolder in a folder in the root folder. When I
log in to the initial Zope management screen, with a user with both
Manager and Owner roles (andy), I get this as debugging output:

2000-03-29T21:23:04 PROBLEM(100) GUF gudid is   

Even though I am not going into the folder with the GUF. Probably this is
due to just accessing contents information. Note that it says "gudid" and
not "gufid", which is what's in the code, which is a bit odd. It's also
printing some squirrely 8-bit character that doesn't paste in.

The folder with the GUF (XXX) has acquisition turned off for all
permissions, and all permissions enabled on Manager. The GUF itself has
normal security. In addtion to this, the user is assigned the local roles
of Manager and Owner in both XXX and XXX/acl_users. It doesn't seem to
matter whether these local roles are assigned or not.

If, as my user with Manager and Owner roles, I try to get into XXX, this
happens in the debug log:

------

The first three messages seem okay to me. The problem is that it is only
validating my user for the Anonymous role, and from then it seems to be
working as it should: It pops up a login document. The login stuff and
authentication seems to work properly. But it is not getting the correct
Roles from the top-level acl_users. The superuser works as you would
expect, until you look at the debugging info.

The difference here is on the first try (with andy), it crawls up twice
and fails each time, but with the superuser, it again crawls up twice
(gets just the Anonymous role at first), but on the second crawl,
validates the correct roles (note that manager appears twice).

Tracebacks dont look useful, just raising the LoginRequired exception, and
the only reason I have a traceback is because of debug mode.

Is this a bug (whose bug is it, anyway?) or a feature?

(BTW, that's a Python XXX, not a porno XXX. So don't flood the box looking
for pix of hot naked teen action. You won't even find any hot Python
action yet.)

Subject: [Zope] Zope in Jpython
Message-ID: <000501bf99d0$f37f0b60$770da8c0@bbs>

Zope is greate, all reviews say so. Most of the reviews complain the
documentation.

I believe all come to known zope have experience the same difficults and all
those remains can feel the power of zope.

Not only the documentation is matter. Under the greate architecture, zope is
inconsistance, non-intutive, and mistiness.

To be fast to market is not enough, it must also easy to maintain, endure
greate and fast change to make zope success.

To make good use of zope, one should paid more attentation on content
instead of control. Making separation of control and content as deep as
possible. Write re-usable, structural components.

I believe the following is very important :

1. re-introduce unified naming convention. encourage developers to change
over this
2. move un-necessary codes from the zope kernel to user space: <base> <lang>
...
3. support of unicode
4. make zope content easy to co-operative with current technonlgy especially
search engines. zope oodb is greate, but it prevent other apps to access the
data, so it is difficult to contruct a local search facility.
5. support cvs style versioning
6. multiple output format
7. new scripting language, encourage separation of content and control, may
be more xsl and xpointer style.

Converting zope to Jpython have the following benefits:

1. Unicode support
2. draw other java components : for example, several  xml tools being
develop in Apache.org is very useful.

If a complete re-write is not economic, at least DC should consider how to
separate the content and control in zope, make the syntax easy to learn and
use.

Ok, I've got the z sql method & odbc working correctly, and from a screen i
can input a date ( as text string) and product which then returns a nice
 and fast! ) graph of dates on the x axis versus avg values on the y. Now
from the documentation you can only get back 2 variables to use in the graph
but i need to plot about 5 Y values. So i thought about multiple graphs but
can't get that to work either.
    My solution was to create 5 radio buttons asking for what type of plot
they want, then based on the button selected fire off the appropriate
<action>. I'm new to Zope so i can't seem to get the Conditional statement
to work right on the <submit>. Anyone with any experience in any of this
please send suggestions. Thanks.

I have a sprinkling of Pystones for everything from the original Qube to a
P3-700:
http://weblogs.userland.com/qube/stories/storyReader$289

If you're doing any Zope work, you might consider as a minimum a RaQ3. Even
then I would think twice. There's a massive performance boost with the
P3-600 and P3-700.

I don't have any results for a RaQ3, but based on the CPU, it's not at all
an ideal Zope environment.

If you want a fast, cheap, Zope box look at the G3-450s. Even an iMac. Or a
Celeron. But not the Cobalt lineup.

Hi All,

Ive created a Product on my site that clones a file, then changes its
properties and
places the new file into whatever folder Im accessing that Product from.
It was working fine until I moved a bunch of folders. Basically, In the root
folder I
had a folder called website, then within that, folders called topstories,
sports,
weather etc. I copied the topstories, sports, weather folders to the root
directory and
then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to
access
manage_changeProperties". I am listed as a Manager of the site though, and
seem to have
full permission to do anything. I have discussed this with the superuser and
we can't figure
out why this happening.

Hello:

I'm not getting dtml-let. I use it to create a variable that I can access, correct?

Say I want to initialize a counter, and change it from 0 1 each iteration of a loop.

This will print out rows of a table with alternating background colors:


<dtml-let x=0>
</dtml-let>

<dtml-in "getElementsByTagName('book')" >

<dtml-if x==0>
	<tr bgcolor="DDEEAC">
<dtml-else>
	<tr>
</dtml-if>


write out some html

</tr>

<dtml-if x==0>
	<dtml-let x=1>
	</dtml-let>
<dtml-else>
	<dtml-let x=0>
	</dtml-let>
</dtml-if>

</dtml-in>
</table>
</dtml-with>



The let and if syntax is not good, and I can't read anywhere on how you would accomplish this type of
construct.

Few.

> Bad idea? 

Many.

Java is not an open platform.  Zope depends very much on the current
CPython implementation. Java has 'stability' issues, depending on what
vendor/platform/day of the week it is.  No in-house Java expertise.  Add
to this the list of debatable reasons why doing anything at all in Java
is a bad idea.  The bottom line is probably that we don't trust Java
like we trust C and Python.  If Java sticks around for as long as either
C or Python, then maybe I'll trust it a little, but never more than that
as long as it is a closed platform.

>It seems like a natural way to increase the performance of Zope while

Increase?  I think that's highly debatable.  We could put just as much
effort into increasing the performance of the CPython JVM or rewriting
components of Zope in C and probably get a much higher performance
return than depending on any one of a number of wildly different Java
implementations to give us that.

Consistent, everywhere?  This would require incredible re-writing and
probably break alot.  We'd rather come up with some newer, cleaner
interfaces and deprecate the old ones.  You're in luck, because now you
can propose new interfaces and corrections for existing ones, complete
with your prefered unified naming convention at the Interfaces Wiki:

I'm not sure what you mean by user space.  Zope is pretty well
segmented, we do need to clean up the application itself a bit.

> 3. support of unicode

Ah, as soon as python does, we do.  Also, soon there will be a Japanese
Vocabulary to support Japanese searching of text, and after that we are
going to try Chinese.  In Zope 2.2, using these examples, you can create
a Vocabulary object for the language of your preference.

This is kind of vague, nothing in ZODB is specific to the way Zope
stores its objects, currently Zope uses a FileStorage but there is
nothing preventing you from creating an XMLStorage or a
FileSystemStorage or a ReiserFSStorage or what have you.  Doing what you
want here can be done right now, it just has do _be_ done.

> 5. support cvs style versioning

Same as 4, all of the hooks and technology is there to support this, it
just needs to be done.

Can you define this better?

Well, there is some experimental stuff going on, but probably not
anything like xsl or xpointer, more like dealing with templates applied
to textual content that has structure.  Also some people are working on
introducing some more xml based tools in Zope.  Keep in mind also that
all the hooks are there, you just have to come up with an
implementation.  There is nothing in Zope that says you can't look at
the entire thing as XML or whatever, in fact, this can all hapen right
now.

This is one of the few genuine benefits, and soon it will be supported
in CPython so it's not a very pressing issue.

You can still use those components with Zope; why would you want them
all to be in the same language?  If those components have well defined
interfaces that Zope can work with why does it matter what language they
are written in?  I don't see this as a benefit.

Yes, we are working on these issues right now.

<dtml-let> tags only set that variable within the <dtml-let>context</dtml-let>
tags. 

The task you wish to do would much easily done using the variables set by
dtml-in. Eg <dtml-var sequence-index> will print out the 'count' if you like
for the list.

<dtml-if sequence-start> </dtml-if> (from memory?) will evaluate if it is
the first iteration of the loop.

<dtml-if sequence-even> and <dtml-if sequence-odd> will evaluate odd and
even iterations of the loop, which is what it apears you want todo.

Check out the zope quick reference document for documentation on
this

To concur with Michel --  JPython is a wonderful java prototyping
environment.  I know that people use it to do real work, as well...

But, I'm really not sure that it gains you much, given Java's high
footprint on anything that is non-Windows/non-Solaris.  

Also, JPython loses some of the nicer features of python (such as
multiple inheritance; at least the more recent functional versions
did, last I looked, 6 months ago).  This might be problematic,
depending on the guts of Zope.

If you really want Java, I suggest sticking with Servlets.  Or fork
the source code... 

But Digital Creations, please don't reimplement Zope in JPython...

best,

Let me warn you, you are allready thinking too procedurally.  Remeber
DTML is a _template_ language.

Let defines a new scope for variables, the scope being defined by the
let block.  Each time you use the let tag, you are creating and then
immediatly destroying the scope of your variable.  If you want to use
'x' in your DTML code, that code must be contained in the let block that
defines x.

What you are doing is easily done using the 'sequence-even' attribute.

<dtml-in "getElementsByTagName('book')" >
  <dtml-if sequence-even>
    Print stuff for even rows
  <dtml-else>
    Print stuff for odd rows.
  </dtml-if>
</dtml-in>

Message-ID: <38E2BA94.FF282F9B@suprize.com>

Hi,

    Since zope was introduced, I've created a handful of objects in
the nice application server and make great progress on several projects.
Thanks to DC and supports from people in this forum.

    Lately, these handful of objects keep growing and, from time to
time, I need to use find an object ID based on my vague memory. The
"find" tab in the zope interface grabbed my attention. But it seems
only accept full ID name to be put in the search field. Is there a way
to let "find" search by pattern or wild card characters? I've tried
*<pattern>%, %<pattern>%, or just <pattern> but with no luck. Please
advise and sorry for my bad memory for which only part of the names 
can be kept for a short while.

However neither of the above works, the latter gives a traceback error,

The above is used inside a DTML Method which is called by passing parameters
to it from a DTML Document. qry_name is one of the parameters being passed.

Any help appreciated.

etcUserFolder is an older piece of unsupported software that may have
compatability problems with newer versions of Zope.  I don't know if
anyone out there maintains it actively.  Without similar reports I would
tend to believe that this is because etcUserFolder has not be changed to
reflect recent changes in the API.

You can do some string matching with the 'expr' field, this lets you
type in a python expression that is evaluated against each object, for
example "id[3:] == 'bob'" would match all objects beginning with 'bob'. 
There is no regular expression facility.

This probably won't be expanded on because to a point the find tool just
doesn't scale.  If you want advanced wildcard searching of textual
content, use a Catalog.

I think it's a thread problem but not anything linux related, or at
least I'd need to see proof of that.

Wait another day, and try -t 2.  See what happens.

I wonder if the fact that manage_changeProperties was a latecomer to
security makes it different in other ways.

Subject: [Zope] Problems using DateTime in dtml and python. Help...
Message-ID: <38E2F888.51937800@ne.mediaone.net>

I have been building an interface for call reports from a MySQL database
on linux slackware 7 using
recent source distributions of Zope ,MySql and python. Besides a messy
bout with the ZMySQLDA
source, which is now not an issue,  I've  done OK. The problems:

1:

  I can call the DateTime() function from dtml like this-
    <dtml-var "_.DateTime(a_later_time) - _.DateTime(an_earlier_time)">
and I get what I need - a duration of time- but in days.  Is there a
method to change this to
minutes and seconds or do I just do my own math ... result * 24 * 60
etc... Whenever I try to
use the  DateTime  objects, eg fmt=DayOfWeek etc, I get invalid
attribute errors.

2:

I would rather do this work in an External Method, but when I try to use
DateTime() in a method
I get a Name Error when I try to update the Eternal Method in Zope.

So I went  to the python command line.
>>> from DateTime import *
Traceback (innermost last):
 File "<stdin>", line 1, in ?
ImportError:No module named DateTime

Obviously, I have some work to do, but what ? Recompile Python or Zope ?

How do I get DateTime to be recognized as a module?
I noted that the contents of  the Setup file in
/Zope/lib/python/DateTime are commented out-
 # install DateTime.py
 # install DateTimeZone.py
I uncommented them for kicks and reinstalled Zope with the same results.

It seems to me I'm missing something OBVIOUS.
And help greatly appreciated...

A GUF object has just been instantiated. The squirrely character needs

Its a bug. I'm putting together a patch release as we speak, and I hope
to have this fixed (next on my list). I was hoping that the 2.1.6 release 
would make all this crawling-up-the-tree business unnecessary but the 
change proposed doesn't seem to have been implemented.
(see http://lists.zope.org/pipermail/zope-dev/2000-January/002940.html )
I vaguely remember that the LoginManager for the PTK was going to make
use of this, but I havn't had time to pay attention for the last month or
so :-(

The Anonymous role being returned the first time is a recursion check
kicking in - during the authentication stage, we need to access your
methods in the GUF, which kicks in the authentication system again...

My bug.

I need to get the ZCatalog to update it self when I do new postings.
I have tried this

<dtml-call "Catalog.manage_catalogFoundItems(REQUEST, RESPONSE, _, _,
obj_metatypes="MyClass")">

But I'm not sure about the REQUEST and RESPONSE...

Subject: [Zope] problem with dtml-if
Message-ID: <v04205500b508b9940b8b@[130.227.115.56]>

hi,

I have this code in a dtml method called "test":

<HTML><body bgcolor=#ffffff>

<form action="test" method="get">

<SELECT NAME="day">
	<dtml-in 
"(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26 
,27,28,29,30,31)">
		<OPTION VALUE="<dtml-var sequence-item>"<dtml-if 
"_['sequence-item'] == day"> SELECTED</dtml-if>>
			<dtml-var sequence-item>
		</OPTION>
	</dtml-in>
</SELECT>

<input type="SUBMIT" name="SUBMIT" value="go">
</FORM>
</BODY></HTML>

It should "remember" the day selected and choose that as the default 
when making the select box. But for some reason the sentence:
<dtml-if "_['sequence-item'] == day"> SELECTED</dtml-if>

Doesn't work. I have also tried ... == _[day] ... == 'day'
...and a lot of other stuff but with no positive result.

I start the page with zope:8080/test?day=1

Regards

What can I do to logout with standard basic authentification?

[exec. summary -- concurrent requests becoming serialised; suggestions]

Hi,

I ran your test script on our zope server, and managed to view many other
pages while zope was parsing the page...

It looks like you might not have enough available threads (or maybe database
connections?). 

It's strange that only one request at a time is processed -- are you perhaps
using Zope in single-threaded mode (using pcgi_publisher; see
doc/WEBSERVER.txt for details)? You can set the number of threads Zope uses
by changing NUMBER_OF_THREADS in Zope.cgi; the default is 4. Note that
increasing this number will also increase Zope's memory footprint, as each
thread gets its own copy of the persistent object space.

It may also be that your machine is simply choking on that test script -- it
takes a while for zope to parse and render it. Despite python switching
between threads every n bytecodes, such a script (rendering one million
items) is going to put quite a load on the machine!

On your database queries you may be using a database adaptor that doesn't
give up the global python interpreter lock during transactions. This
prevents other threads from executing. What database and database adaptor
version are you using? See http://www.zope.org/Members/petrilli/DARoadmap
for details. There is a brief description of why the interpreter lock exists
in the python FAQ, section 4.88 (http://www.python.org/doc/FAQ.html#4.88).

Although unlikely with only one user, it's also possible that you could be
running out of database connections. By default, a maximum of seven
connections can be opened to any database you add. This limit can be set by
adjusting pool_size in zope_dir/lib/pyhthon/ZODB/DB.py (later versions of
Zope allow you to tweak these things in a custom_zodb.py file; try searching
the mailing list for details). Note that increasing pool_size will again
increase Zope's memory footprint, as query results are cached on a
per-connection basis.

hth,

Hope this is not too stupid a question:

How do I test a version without saving changes?

When I use the view option from within the management interface I only get
to see the 'live' (ie public) version and not the version that I'm working

Hi,

With basic authentication, the user's browser caches the username and
password, and sends them along with each request. All you can do to
invalidate the cached values is raise an "Unauthorized" exception.

<dtml-raise type="Unauthorized">
 You have been logged out. Please log in again.
</dtml-raise>

This sends an HTTP 500 Unauthorized back to your browser, which should
display the basic auth. login box again.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.12.html for
details.

Try:

_['something'] means I want the value with the literal key of 
something.

_[reftosomething] means I want the value with the key which is the 
value of reftosomething, if that makes sense.

The problem with this is that the browser will not clear its cache of this
valid username/password unless the user clicks 'OK' on the login dialog box
that pops up.  If the user clicks 'Cancel' then the browser assumes that
the user doesn't want to change the username/password, and keeps the
existing one in cache, hence, a reload of the page will be successfull.

Does anyone know of any tricks to get around this?

Hi Jonathan,

You might want to check with the ZIP - Zope Internationalisation
Project. There was some talk about a word by word translation service
lately. You might find interested partners there! You can find the
ZIP-Maillist home at <http://www.eevolute.com/mailman/listinfo/zip>

Really? What would you put on the Macs? Linux, OS X or MacOS?

What makes the Celeron superior to the Cobalt-setup in your opinion?
I thought the Cobalts where rahter high-speed (full) pentiums and
that the Celeron is not well suited for server use??

In my browser (Netscape) this works if you're following a link after
aborting this process.
Another (not very nice) method is using java-script closing the windows.
Recently found no better hints.

Thanks for pointing that out. 

As I understand it, this is a limitation of the HTTP Basic Auth. spec. RFC
2617 deals with this, and says that a client may preemptively send the Auth.
header with requests without receipt of another challenge (section 2). The
browser sends this information for every request in the zope realm (if it
didn't, you'd get the login box on every page). The server also sends an
authentication required header for every page that is protected, so this
behaviour in fact is quite logical.

The only way around it is to use a different authentication mechanism, like
Generic User Folder, et al.

Oh, yeah, and I meant 401 Unauthorised... what a week...

So, ZTables is going to die silently? I don't know much about it, but
considering the number of times I use TinyTable I would say that
ZTables is a needed datastucture for handling larger amounts of data.

Of course I understand and encourageDC to sell it as a commercial
extension, but I have problems understanding why they don't release it
to
the public if they lost interest. Anyone from DC?

Hello!

My current ISP has no interest in supporting Zope and will not install some
kind of 'Long Running Process', so I can't install it myself...

Can someone recommend an ISP that supports Zope?

I found Armored Internet, but it seems like they only support Zope for
Business Services (and they also charge $37.50/month for it). So if someone
knows an another ISP, preferable cheaper, PLEASE let me know!

Hi,

I have learning Zope for 6 months and have been
following the mailling list. I come across the
following news :  

Python 3000 will not be backwards compatible. 

Question :
How will it affects Zope ?

Sorry to be picky here but, quoting from Table 15 on page 21 of the DTML Guide:
missing - Provide a value to be used if the ariable(sic) is missing, rather than raising a KeyError.

This is what I ended up doing :-)

Is it just me or does it seem silly that:
<dtml-var HTTP_REFERER missing='/'>
works as expected but
<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>
doesn't, even though they're logically the same thing?

The KeyError should be caught when evaluating the expression as well as the name in dtml-var :(

I might chuck this in the collector at some stage...

That's because 'day' in the request is a string which you compare to an
integer.
Try:

<dtml-if "_['sequence-item'] == _.int(day)"> and your code should work
fine.

BTW you can shorten you <dtml-in> statement with the range tag:

<dtml-in "_.range(31)"> will give you the same output.

Zope won't run on MacOS. It would have to be either Linux or OSX or BSD.

It runs Python faster than a PIII of the same speed. I'm assuming that's
because the cache, while half the size of a standard PIII, runs at full CPU
speed. That it supports only a 66MHz bus and memory may cause it to not
perform as well under load. I don't know. I  don't have the resources to
test that sort of thing properly.

There's more to a building a server than its Pystone rating, but it's a
start when you start looking at putting together a box.

Subject: [Zope] variable SQL insert method
Message-ID: <38E3368A.98950BF0@rrsg.ee.uct.ac.za>

Hi,
I have a database with 3 tables. I would like to create a ZSQL method
for inserting data into the tables. I started by creating a separate
method for each table, but that seems a bit of a waste. Ideally I would
like to have one method, "addEntry". The template would look something
like:

<dtml-if "tname=='supplier'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar sup_name
type=string>  etc...);
<dtml-elif "tname='manufacturer'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar man_name
type=string> etc...);

</dtml-if>

The problem is that I have to specify the arguments in the argument
list, and the arguments are different for each if clause in the above
code. Is there a way around this?

thanks
Allen

if get_returner_id(xxx) returns an empty list, then it _should_ return
nothing.

as the <dtml-in will be executed 0 times.

(untested, and will need finishing off)

Put ALL the arguments in the ZQSL method's arguments section, but give them all defaults (eg put
myvar_name='' in the arguments section)

Now, to make sure the right ones have been supplied, you need to put in an extra level of dtml-if in
each branch of your current dtml-if, something like:
<dtml-if "tname=='supplier'">
 <dtml-if "_.has_key('var1') and _.has_key('var2')">
  ... your insert here...
 <else>
  ... do something to warn of the error, such as a dtml-raise
 </dtml-if>
<dtml-elif ...>
...

Hi,
I just ./stop and ./start'ed two Zope servers that were taking up 
rather a lot of memory;

   PID USERNAME THR PRI NICE  SIZE   RES STATE   TIME    CPU COMMAND
   841 nnle      12  33    0  395M  318M sleep 177:24  0.00% python
   834 nnle       9  23    0  531M   14M sleep 101:20  0.00% python

Is there any way of telling what objects are taking up this memory - 
could it be a memory leak in Zope at all? I'm using src-2.1.3 on 
Solaris because I still use the /REQUEST hint to see what my 
variables are.

cheers,

Now - LinuxPPC (my Mac at home that gets 900 pystones is usable for 
me to do dev work on).
Later - choose from OS-X or LinuxPPC
You can't (easily) use MacOS because Zope has some unix-centric parts 
that don't translate well to the Mac.

>What makes the Celeron superior to the Cobalt-setup in your opinion?

The Pystone scores are higher
Celeron-400a
Pystone(1.1) time for 10000 passes = 1.78
This machine benchmarks at 5588.87 pystones/second
vs
Qube2
Pystone(1.1) time for 10000 passes = 8.81
This machine benchmarks at 1135.07 pystones/second

Sorry, not qualified to answer that bit. All I do know is that we 
have a 700MHz PIII here that gets 10,500 Pystones against our 
Enterprise 450 with ... 2700. As the maintenance on the Sun kit is 
roughly the same price as the PIII, you could say I'm not overly 
impressed with the Sun...

Hello,

I've just discovered Zope, and would like to get more information about it
as it
seems quite interesting . But I'm not sure I could use it for the web
project I'm
working on.

First, I'd need to stock XML files in an object database like the one
provided with
Zope. What kind of requesting language may I use ?
XQL ? Xpath ? XML-QC ? OQL ? XOQL ?

Second question, is there a java API integrated in Zope ? If not, is it
possible to
interface Zope with others java products as Resine, servlet engines, EJB
server...?

Thanks in advance

Bruno Faure

Subject: [Zope] dtml-return'ing the result of a SQL select (does not work)
Message-ID: <38E35092.A8838265@knoll-is.de>

Hi,

I just tried to implement something as described in the How-To
	How To: Use GenericUserFolder with an SQL database
It does not work. The problem boils down to the fact that I can't
dtml-return the result of a SQL query.

I wrote the Z SQL Method 'qryTest':
	select * from mytable

This method can be executed without problems. It displays all rows in
the table.

And I wrote a DTML Method 'returnData':
	<dtml-return qryTest>

When calling the method I get
	Resource not found

Traceback (innermost last):
  File D:\Programme\uZope\lib\python\ZPublisher\Publish.py, line 214, in

Watch out, this might be confusing, since Subscribe is a permission
referencing in the other direction (eventually actually needs to be
placed somewhere seperately). You have to set that checkbox in the 
account, that is supposed to access that data in it's default view,
or in that account session you must use the "Go-control" to switch to
the shared account.

Does the method return the full text if you call it
directly?

like:

http://your.zopeserver.dk/yourZclass_instance/PrincipiaSearchSource

you should get the raw contents of the instance..

If you don't , somethings wrong with the method or its
placement..
i think product/product_entry/methods is the right place..

If you get the raw text returned, the fault is with your
Zcatalog.. Have you updated it after adding the pythonmethod
??
- Checking the status-view of your zcatalog can often help to see
if it has updated correctly..

Subject: [Zope] ZSQL arguments
Message-ID: <E12afEQ-0004UC-00@marvin.nipltd.com>

Hi,

ZSQL methods can have two types of string argument, string and 
required, where required is a non-empty string and a string is (one 
assumes) a potentially empty string.

Although does not say in the ZSQL users guide, it would be nice if 
strings were also not required to exist as arguments, which to my 
mind is the logical progression of allowing an empty string.

The reason I want to do this is that I am writing sql methods which 
build queries based on the existence of certain arguments.  
Obviously I can code the logic to test for empty strings, but it 
would be neater and simpler to be able to simply have

<dtml-if myarg>
...

The other reason this would be a neater solution is that it would 
avoid the need to set up lots of empty arguments in the dtml which 
calls the sql method.

Comments?

Cheers,
Stephen

Sorry, Tom,

I was blabbering last time about hasattr. The right solution is of course:

def recursiveMethod(self, obj, result):
     if hasattr(obj, aq_parent):
            result.append(obj.title)
            recursiveMethod(self, obj.aq_parent, result)
     return result


which you will have to call like this (assuming you external method in Zope
is called recursiveMethod):

<dtml-var "recursiveMethod(<obj>, [])">

Working with a keyword argument didn't work for me. I'm sure someone can
explain you why (but I don't have time for sorting that out right now)

Zope returns a key error on "set". The same appends for 'append' method, as if,

I eventually found the answer by creating an external method :

def SetValue (self, dictionnary, key, value):
    """Ajoute une valeur ŕ un dictionnaire"""
    dictionnary[key] = value


Which you can call with <dtml-call SetValue (REQUEST.form, 'tata', 'titi')>. It
works !...

*Increase* performance by rewriting in Java?  You've been reading
Sun's press releases again and, worse still, actually believing them;
don't make that mistake! :) 

I can think of any number of improvements that could be made to Zope,
but a translation into another language, with no clear idea of what
actual problem would be solved by the translation, isn't one of them.

	Also, take a look at: www.step-thermodynamics.com

	Their primary business is selling specialized cooling systems
	for processors, which they bond to the processor.  As a result
	they only sell their cooling system with a processor.

	They provide a lifetime guarantee on what they sell, and they
	also guarantee that a processor will run at a specific MHz
	(which in the case of a Celeron 333a processor is 500 MHz if
	I remember correctly).  That particular configuration uses a
	100 MHz front side bus speed.

	A friend of mine has got a couple of dual processor boxes with
	Abit BP6 motherboards (socket Celeron motherboards) with two
	Celerons each running at 500 MHz.

	For any task that requires fast cache, but not a lot it, they
	are great systems.

Ok.. so I opened up a can of worms.

Thanks to everyone for setting me straight. I do think, though, that
performance and benchmarking should be an issues on the tips of DC tongues.
I have been doing a lot of benchmarking (and will publish results soon)
trying to figure just where the bottlenecks are (DTML, references, SQL,
size, caching). The good and bad news is that there seems to be no
difference in many of the different tests. I can get a MAX of 40 requests
per second, and that, is that.

The reason I asked about JPython and performance was because I get a lot of
developers telling me that Servlets are much faster. Now, that being said I
am about to set up a website with servlets and pound on it till it bleeds to
see if it is true.

One of the comparisons that would be nice on Zope.org would be the servlets
vrs Zope. (JServ, Enhydra, etc).

Thanks,
J

Hi,

I ran into trouble when trying use PIL (python imaging lib) in zope
product. 
The problem is that zope's App.ImageFile is used by PIL's internals
instead of PILs ImageFile and of course this doesn't work.

Any ideas how to fix this problem?

Sure. You just need to 'packagize' PIL. 

Place the PIL directory somewhere in your
Zope's python's path. Add an __init__.py
to the PIL directory.

Inside the __init__.py place the following:
# Add any additional PIL modules that you want imported.
# This is one, long import statement that my email clien will
# wrap.
import Image, ImageFile, ImageEnhance, ImageDraw,  _imaging, GifImagePlugin, 
JpegImagePlugin, PngImagePlugin, BmpImagePlugin

Message-ID: <38E37C81.365E6845@knoll-is.de>

Hi,

I just found something in DT_Var.py which I mean is a bug.
The function thousands_commas uses a hard coded ',' to as thousands
delimiter. I think it would be best to use locale.format instead for
this purpose.

Is there anybody how can incorporate this change into Zope?!

One more related question: How can I print the current currency symbol
in Zope? I could not access the locale namespace in a dtml method.

Thank you.

I can think of one: I wrote my first program in php in some minutes, while
my first zope silliness took me days.

 - BUT -

now I'm in this mailing list so I can flood you with questions.


Please keep in mind that I'm a total newbie, at the moment I know
little more than Nicholas Petreley about Zope. I'm fluent with python
and slow but steady with html.

My first site is for an antique trader (my father): four languages,
lots of photos with descriptions, some search methods, some registered
users, a private addressbook.

There will be an "uploader" interface for my brother, a public and
a "frequent customers" interface. I don't think the Photo product
is stable enough for use, so I'll try and write something by myself.

If I use a "pure" zope provider, do I need to keep the photos on
the ZODB?

Is it possible to write to the file system via an external python
method, so that I can:

 * receive a photo with netscape
 * give it an unique filename
 * write it to the file
 * update the info (filename, descriptions) on a SQL table

 and then

 * reference (from DTML) or delete (from python) the photo by the
   filename stored on the SQL table

 ?



The trouble with Zope is not that it isn't documented, but the
documentation at first makes me fell stupid. I don't know why.

It is like loving a girl you didn't have the chance to talk to.
It makes me feel stupid.

Maybe the fact that I need a 21" to look at my source, and I have to
look at the source of the page returned by the browser to see the
stack trace with my error (when there is a stack trace), has something
to do with the stress I am having during my learning sessions.

Will zopezilla (or mozzope)? enhance my Zope Experience?



Thank you for reading this far.

Subject: [Zope] namespaces and uploading files etc
Message-ID: <38E37FB9.25E18857@rrsg.ee.uct.ac.za>

Hi,
I've written an external method that will write some data to a specified
location in the server's file system. I would like a user to be able to
upload a binary file, and for the external method to then write that
file to the local file system. I understand that when a user uploads
something using an <INPUT TYPE="file" NAME="uFile"> that the file is
encapsulated in a FileUpload object. That data would be accessible in my
external method using REQUEST.uFile.read().
However, suppose my external method is defined as :
def writeFile(self, file, rootdir, filename):
    ...write data using f.write(file.read())
    return filename

I would like the argument "file" above to be a reference to
REQUEST.uFile. Also, the "filename" that is returned would be the actual
filename used (it may have been altered due to filename clashes or
whatever).
I tried using the following dtml to call this method:
<dtml-let filename="writeFileLocally(_.None, _, _.uFile,
  '/usr/local/ZopeExternalFiles/Components', _.uFile.filename)">
<dtml-var filename>
</dtml-let>
However zope complains...
I'm obviously still fumbling with zope's namespaces.

Thanks
Allen

Comparisons of this type are always quite difficult to pull off. I know that
the applications I've created are rather Zope-specific. I designed them for
Zope and they take advantage of Zope's features. It would be really
difficult to try to do a reasonable comparison, because Zope has features
the other systems don't. Sure, I could make a servlet that acts kind of like
an app of mine, but how would I simulate retrieval of data from the ZODB and
acquisition and the like?

I'm sure that I'm paying a performance price for things like the ZODB and
acquisition... but I think that price is offset by the productivity
improvements that I get as a result.

Convert the DateTime objects to seconds before subtracting::

  <dtml-let early="_.DateTime(an_earlier_time)"
            late="_.DateTime(a_later_time)"
    <dtml-var "_.float( late ) - _.float( early )">
  </dtml-let>

You can use '_.int(..)' or '_.long(..)', to, truncating to whole seconds.

Put an __init__.py in the PIL file that says:

import Image, ImageDraw 

and have it import whatever you need from pIL.

Then you can just do 
	import PIL
in Zope.


The Poll Product has some instructions on this.

I have a zope ISP (hurrah.com) and am trying to determine how fast/reliable
they are.  Is there a way to compare Zope ISPs for speed and reliability.  I
would imagine speed is the easiest to test and reliability is subjective and
based on historical knowledge.  I am just having trouble telling if my test
version of Squishdot (and my test site in general) is really supposed to be
as slow as it is.  I am used to working with a large ISP (Verio) with no
Zope.

Any ideas on how to compare or test would be greatly appreciated.

Isn't it 32kb for Postgres?

Unfortunately, the photos are up to 350kb.

Ok, ten smaller objects could do :-)))

Subject: [Zope] Date Zone Problem
Message-ID: <20000330165619.76957.qmail@hotmail.com>

Hello,

Last March 26th Portugal changed to GMT+1.

ZopeTime() returns, for instance, "2000/03/30 16:00:00.000 GMT+0".

16 hours is correct but I think it should give a GMT+1 at the end of
the date?

I found this because I'm having this problem:

I have a object with a property date that when created first time
with the factory add method uses the manage_changeProperties with
the date value added to request with,
<dtml-var "REQUEST('date',ZopeTime())">.

The object is cataloged. Then I make a search to get the objects and
sort them by date. When I render this objects dates If I format the output 
using fmt="%C %Style" the date presented is "2000/03/30 15:00:00.000 GMT+0", 
one hour less!!

Since this is not right cause the real hour is 16 I work around the
problem and discovered that the TimeHours() function returns the correct 16 
hours. That resolved my output problem.

But then again a problem emerge. I have a form to update my objects 
properties, in this case, the date property. This form when rendered
writes a <input type=text:date name=mydate>. When submited a strange
thing happen. If I output the date of this updated object with the
fmt="%C %Style" format the hour will now be correct, i.e, 16.

I though then that the "text:date" type in the html was important for this 
happening.

But the problem now is that when sorting my objects this one will be sorted 
using 16 as the hour but other objects that I did not updated, i.e, dont 
passing them trough the "text:date" form, will be giving 15
for the sort.

Questions:

Is this a internationalization of zope related problem?
Does the GMT+0 instead of GMT+1 is a zope/python bug?
Am I missing something about the international date zone system?

Best Regards,
Julio

I did a private extension to DT_Var.py which incorporates 
the modifier "german-money", which returns 
1&nbsp;234,5 for 1234.5 
Just because I needed it.

I did not mention it to the group since I want a much cleaner and more
general approach for supporting multiple languages.
I dont think we could handle this with locale, since the actual page
could be in a different language.

I've since moved back to 2.1.4 and it works fine there. Will be setting

Can you tell me what products? I know that if you are using

then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to

No, Zope can't, especially Python can't, because it trys to evaluate
something like sequence - item.foo.

So try

<dtml-with sequence-item>
 <dtml-call "foo">
</dtml-with

or:

<dtml-call "_.['sequence-item'].foo">

I've had exactly the same problem. I put 2.1.6 and it breaks (user
authenication), I put back in 2.1.4 and it works fine. I'm also just
using straigt Zope. Just so you know it's not isolated.

Too much effort to fix it.  We don't have the time, we are working on
too many projects as it is, even discussing ZTables takes more time than
we have.

Releasing it to the public would still take time, someone would need to
maintain it, but to maintain it they'd first have to understand it, it's
complex; as complex as the catalog.  If we threw it out to the community
I suspect it would die there also.

Besides, TinyTables could be updated to support more efficient data
structures like the BTrees that ZTables and ZCatalog use.  ZCatalog + a
more efficient TinyTables is probably 99% of ZTables.

If one makes heavy use of TinyTables but needs more functionality (but no
RDBMS) I suggest he/she takes a look at Metakit. (www.equi4.com). This
amazing software deserves more attention than it gets and has already a
very nice interface to python. Returned rows behave more or less like
Zope Record objects. You can do sophisticated stuff like joins
selects etc but it can also be used in a manner similar to TinyTable. It
is transactional and *very* fast/efficient. Currently in not multithreaded
so one needs to serialize requests. I think the author, Jean-Claude
Wippler mentioned that he is working in a thread safe python version (the
TCL one is out).

A Zope interface would have beed nice ...

yes, only in pythonish these are called attributes.

Hm, I tested it. It works for me. Can you tell me where it doesn't work and
in what way? Does it fail. Is there a traceback? Remember it will still bail
out (with an AttributeError) if the object has no attribute title!

That is because there is no high level framework with servlets.  There
is no standard authentication framework, acquisition framework, standard
object/relational model, template language, through the web managment
system, object publishing over multiple protocols... servlets don't come
with an HTTP, FTP, PCGI and a FastCGI server.  All of this you get with
Zope out of the box.

It may very well be.  With the subsequent open sourcing of ZEO however,
you could scale your Zope application invisibly to a hundred machines,
how far can  you scale that Servlet without making any changes to it at
all (or not paying money)?  Requests per second is only one tiny factor
of scale, and when you scale beyond a handful of machines it becomes
less and less important.

That's because Zope can't write it (that's what the 'w' means).  The
user you are running Zope as (if you are root, Zope turns itself into
nobody) does not have permission to write to your var/ directory.
 
> Q1.  Why is Zope looking for Z2.pid if I installed it WITH PCGI?

The Z2.pid file contains the process id of Zope, it allways writes it
and has nothing to do with PCGI.

> Q2.  If Zope still needs Z2.pid with PCGI, how do I get the file there?

Zope will put it there if it can write to the var/ directory.

Though I haven't seen any clear statement to confirm this, I believe this
is a very large part of DC's decision to release ZEO. By enabling Zope
clusters ZEO addresses pragmatically several limitations inherent in the
curent state of Zope / Python. As a side effect, redundancy brings with it
answers to concerns regarding reliablility, of hardware, if not Zope
itself, in a mission critical setting.

While some may see throwing hardware at performance / reliability needs, as
inelegant at best, to others with hopes of rolling Zope out for the long
term, this seems like a perfectly reasonable solution. Python and Zope will
continue to improve, and all Zope users will benefit. For now, leveraging
commodity priced hardware is actually about as elegant as it gets.

So, DC has heard and answered, and Zope is the better for it!

The FileStorage format is portable across platforms.  The objects in
that filestorage are portable across Zope, _as long as_ your target Zope
has the same products installed as your source Zope.

Hm. In the example

<dtml-in list>
  <dtml-var foo>
</dtml-in>

the iteration will change the namespace to that of each sequence-item
automatically. So the foo asked for will always be the foo of the current
sequence-item. Things like
<with sequence-item> or "_['sequence-item']..." are not necessary.

If you iteration is by a number of IDs, as your question suggests, though,
the example is not enough. When you iterate over a list of IDs, the
sequence-item will be an ID (that is a string) and foo will have no meaning
(it will throw an AttributeError).
There are two way of remediating this:

preferrably use objectValues(), like so

<dtml-in objectValues>
   <dtml-var foo>
</dtml-in>

If you _have_ to use a list of ids, things get more complicated

<dtml-in Ids>
  <dtml-var "_.getitem(_['sequence-item'].foo)">
</dtml-in>

(sorry about that)

All code is untested, but it should work.

OK, this is probably a stupid question, but how do I fix it?  I tried:
changing the /Zopedir/var/ folder and file settings to user=ewalstad,
group=users and had no luck running ./start.  I also tried copying one of
the other .pid files and renaming it z2.pid; that didn't work, either.

Any advice is appreciated.

Replying only to the last sentence:  Add a DTMLMethod in the root of your Zope
(call it maybe "debug_request"), with the following body:

  <dtml-var standard_html_header>
  <dtml-var REQUEST>
  <dtml-var standard_html_footer>

This works fine on 2.1.4+ -- they only suppress the "direct traversal" of
REQUEST.

Hello all. I'm just starting my first Zope site, and I'd like to create
a feedback form for the site. I have very little "useful" experience
with DTML, especially for logic. Once I create the form, how do I write
a DTML script to process the input (like linking entries to variables,
testing valid answers, raising errors, etc.) ANY help whatsoever would
be greatly appreciated, and all the useful stuff I learn I'd like to
make a how-to from. Real world solutions like this in Zope are few as
far as documentation go....

thanks in advance,

Eron

Access to a version is based on a cookie set in your browser.  So
when you go into the version object and click on work in version,
the cookie gets set.  If you then access your site from that same
browser session, you *should* see the version.  This, at least, is
how it works for me <grin>.  You should see the version on the view
tab, too, though, so I think you must have some problem with your
browser sending the cookie.

Hello everybody!

Please join me in welcoming Shane Hathaway to the Digital Creations
team!!

From Shane's man page:
"""
I come from a small but growing town called Magna, Utah. I
always considered it an underrated city in the Salt Lake
Valley.  I enjoyed my friends and neighbors there and some
of them keep in touch even now.

I have been programming since I was eight years old.  I
enjoyed the Commodore 64 so much that television I still use
is actually a Commodore monitor.  I had to learn to program
early because my parents refused to buy any software--if I
wanted software, they said, I'd have to write it myself. So
I did!

I enjoy singing.  I have sung in many choirs over the years
including the Cyprus High madrigals.  I have sung enough
solos for various functions that it's now easier for me to
sing a solo than to give a speech in public.

If you ever want to butter me up for something, give me a
genuine Brazilian feijoada.  Include every part of the pig
but avoid the hairy stuff.  Having spent two years there, I
hold Brazil close to my heart.

Not long ago I wrote Web Academics
(http://www.webacademics.com), software for delivering
courses over the web.  It was designed to handle specific
needs requested by educators as well as the needs I was
aware of as a student.  I am working on porting the
education-related components of Web Academics to Zope.

Zope and Digital Creations are very interesting to me
because the product is built on solid foundations and the
company is built on a solid philosophy.  I am excited to
begin working with the team.

Subject: [Zope] Mysterious Netscape Upload failure
Message-ID: <38E3CED8.E4A2561D@palladion.com>

After banging my head on it for a couple of days, I just resolved a really ugly
problem for any Zopista who uses Netscape:  any form which contains a file
upload button was timing out, failing to send data to Zope (e.g., I couldn't
create DTMLMethods!).

The underlying cause of this was Netscape's poor tempfile hygeine:  their file
upload control handler was creating tempfiles, which it then never bothered to
clean up.  Eventually, it exhausted the tempfile namespace, at which point it
looped pointlessly trying to create a tempfile with an unused name.

I tried several reinstalls, tweaked preferences, all to no avail.  The solution
was to scrub the temp dir of all the ns*.tmp files -- everything is hunky-dory,
now.

Looking-for-the-voodoo-doll'ly,

Tres.

Additionally, I would suggest removing the "Acquire Permissions Settings" from the 
"View" permission, and making the "View" permission only available to managers.

This is easy to do, assuming you called the DTMLMethod above "debug_request" and
created it in your Zope Site Root, then you could:

1. Navigate to http://mysite.com:8080/debug_request/manage_access
2. Scroll to the bottom of that long page.
3. Uncheck "Acquire Permissions Settings" next to the "View" Permission/
4. The "Manager" box should already be check, verify this.
5. Click the "Change" button near the bottom of the permission list.

Forgive me if I over-explain.

Message-ID: <200003302208.PAA10382@ifopen.com>

I've got a simple python class that has a data member that holds a list of 
strings (among other things).  I can laod values into this list fine.  
And can query the object and the list is populated.  However, after  I 
restart Zope,  the list for the class instance is empty.  The other data 
values in my class retain their values just fine.

I've got other classes that hold similar lists for which this doesn't occur.

I'm banging my head against a wall - any ideas?

Lets see here ...

KnowledgeKit
LocalFS (installed, not currently in use)
SybaseDAv2
PSQLInput
Cookie Cutter (likewise not in use)
TinyTable (see above)
A small,simple 'nes article' product
Calendar
Standard Zope stuff

That's it.

It is it's own server, so no need for SiteAccess.

In a word, yes. :-)

Here's how I do it on my site. This line tells me when a particular object
(a file object as it turns out) was last updated:

<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=Day>,
<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=pCommon>

The output looks like (for example):
Tuesday, Mar. 7, 2000 11:35am

The extra '_' business in my dtml-var tag is necessary because my file
object has a '.' in its name. I believe that

<dtml-var "spamobject.bobobase_modification_time()" fmt=Day>

should do it if you don't have a '.'

HTH,
Tim

I think you'll find the How-To on creating a mail form very helpful. You'll
find it at http://www.zope.org/Documentation/How-To/Mailform

Good luck.

Thanks, this is what I was looking for. I was adding object names on the the end of it, rather than

I followed the instructions in PIL.  I created a directory called =

I removed the zope/bin/python file, and changed the start file to use =

You're probably mutating the list without informing the instance that you've
changed it.  If you do:

thing.stufflist[4] = 'newstring'

or

thing.stufflist.append('newstring')

...then 'thing' has no way of knowing that 'stufflist' has changed, unless
you replace 'stufflist':

# This can be confusing, since it doesn't look like it does anything
thing.stufflist = thing.stufflist

... or tell 'thing' explicitly:

# This is the official interface to mark an object changed
thing._p_changed = 1

Your changes will also get saved if you happened to change any other
attributes of 'thing' in the same transaction, but as you've discovered this
is unreliable at best.  Explicit is better.

Cheers,

After a minute or two, the directory listing shows up.  Clicking to edit a file

Just on this subject :

a) You may find the Perl mandarin text-splitter at www.mandarintools.com
   very useful. I rewrote it in Python once but my Perl sucks so you may 
   wish to do this yourself. Otherwise, e-mail me for copy ... it's so 
   short I'm sure you'd rather not trust mine though.

b) What algorithm do you use in your searching of text ? Is it just a
   simple frequency tally ?

You will need to use an external python method.

I am currently writing one that will take any sql query and a file name as its parameters and put the results of the query into the
file as  comma or tab delimited records with or without the the field names in the first record.

Will post info here when I have it completed

Subject: [Zope] How do I download the results of a large Query


I would like to set up a link to some SQL query results in comma delimited
ascii that will download the data rather than display it.  I am having two
problems.  First the data is coming up in the browser and I want them to
download it without having to right click and select download.  Second,
before the SQL is completed the browser times out.

I think if I solve the first problem,  the second will be Ok,  Any ideas?

Subject: [Zope] ODBC and MS SQLServer Problems
Message-ID: <20000330163600.A3429@24.64.237.96.ab.wave.home.com>

I am trying to get Zope to play nice with MS SQL Server.  They are both installed on the same Compaq Proliant server.  I can create my database, make it accessible through ODBC and then add a ODBC Connection in Zope by picking my ODBC connection from the list.  I can then use the connection just fine for SELECTs and UPDATEs for a little while (30 mins to an hour). However, eventually I get the following error:

Error Type: sql.error
Error Value: ('S0002', 208, "[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'users'.")

where 'users' is a table name.  Up until this point, it was accessing 'users' just fine, and I can still run queries on it from the SQL Query Analyzer app so I know the table is there.  My only option at this time seems to be to delete the whole database and create it again and recreate the tables.  This isn't acceptable if this system is to actually be used.

Can anyone who has gotten SQL Server and Zope working post explicit instructions.  Or better yet, let me know what is causing the above error.

Thanks.

Not a lot if Zope continues to use Python 1.[5, 6, 7].

<opinion type="personal">

People are making a bigger deal out of this than it needs to be.
I admire Guido for taking a stance and fixing the problems he
perceives in his language;  I've had to support "backwards
compatability" issues in a commercial interpretive language
before, and "It Sucks(TM)".

Here he is being honest, stating that there will be change, but
not knowing the extent, and people are carrying on like it will
be the end of Python as we know it (or to use an Australian term,
"carrying on like pork chops").  When Python 3000 comes out, it
will not render all the Python versions before it automagically
obsolete; people will still be free to use whatever version they
most feel comfortable with (heck, I came across a site the other
day still running 1.3, and quite happy with it - it runs their
_current_ applications fine).  If there is a large enough groundswell,
there is nothing stopping other people from maintaining the "1.7"
version, but I personally can't see that happening (unless Guido
goes mad and puts braces in to denote blocks :-).

It's an Open Source language - you actually have options.

One thing that is kinda amusing (to me, at least) - the fuss I'm seeing
about this is, in a way, a testament to just _how_ _good_ a job Guido's
done as Benevolent Dictator. I've been using python since v 0.9.mumble,
and there's been _very_ _very_ few times where I've had to go back and
change working code because of a python upgrade.

And that's not just the python scripts, I'm also talking about C
extensions. 

Thinking back to a previous place of work where we had perl software of
around 10-12K lines of code, it seemed like every bloody minor rev of
perl5 would break something in it.

P3K has been talked about for a long long time as the "chance to fix
stuff" (ok, it used to be known as Python 2.0, but...).  I, for one, 
am looking forward to it. (particularly if the types/classes split 
goes away).

Here's a silly thing that's always niggled me : 

How do you get Zope to render the DTML that is 
stored in properties of a ZClass ? 

eg. Consider you have a ZClass with a string 
    property called 'my_property'

    In an instance of this ZClass, you set the 
    value of 'my_property' to "Hello <dtml-var x>"
    where x might be a string, integer, image etc

    Now, if a DTML method were to call <dtml-var my_property>,
    it would display "Hello <dtml-var x>"
    How can we get the DTML to be executed too, so that it
    displays "Hello [value of x]". Is there any easy method
    other than splitting this up into different fields ? 

Apologies if this is such a trivial thing. It's
escaped me for ages.

Heh, I just ran into this same problem a few days ago.  For some reason
PIL doesn't install a __init__.py (or at least the RPM of it didn't). 
Check /usr/lib/python1.5/site-packages/PIL for a __init__.py.  If it
isn't there, then make one with this content:

import Image, ImageFile, ImageEnhance, ImageDraw, _imaging,
GifImagePlugin, JpegImagePlugin, PngImagePlugin, BmpImagePlugin

if you are starting zope as root, the following (from the Zope root
folder) should work:

chown nobody access
chown -R nobody var

then you can start.  If you're starting zope as some other user, then
replace "nobody" with other user.  All the files in var need to be owned
by nobody or the starting user.  Copying Z2.pid won't work, because zope
sets it afresh each time it runs.

No, unfortunately, it's not possible.  You can use the Sybase database
adapter to talk to SQL Server 6.5 from Linux.  SQL Server 7 evidently
has a different wire protocol which prevents it from working against the
Sybase DA.  There is no ODBC support for Linux in Zope, and though there
have been rumblings about getting such a thing going one way or another,
nothing concrete has happened.

Not entirely true. You won't be able to use some SQL Server 7 features if
you use the Sybase adaptor, but the standard stuff should work fine.

Once freetds is thread safe, it should also be useful.

It is very possible to get ODBC connectivity using the OpenLink UDBC Multi-Tier
drivers and ZODBCDA. You will have to do some minor hacking, and if you want 
access to any fields longer than 128 bytes, some larger hacking :-)
(There is I think a major bug in SQLGetString in sql.c too that causes
Zope to crash -- I think I have fixed it... at least w.r.t. the UDBC drivers,
sz should be SDWORD [for OpenLink drivers anyway]).

The UDBC drivers are thread-safe (so they say).

I have a FreeBSD box quite happily talking to MS-SQL-7, I implemented this
for a client, so I can tell you how to do it, but, not what I did to get it to
work.The joys of contract programming.

I seem get restarts often when going into the management screen on one
of my servers.
All is dandy until I go to the management screen, then I wait a couple
seconds while it restarts.

Sounds like you are really after the LoginManager, which according to
reports is usable for non-PTK, but not for PTK.

It comes with the PTK, but is a seperate product in development.

Thanks for the answer, I'll have a look. But I would like the basic
structures to be compatible with the PTK, as I might want to employ that
later on. Any comments?

where qry_name is the *name* of the ZSQL-Method that I want to use. Thus if

Message-ID: <00033114332105.02681@tokey.kedai.com.my>

hi all,
i'm thinking of hacking zdiscussion to use rdb as the backend instead of zodb. 
but before i start anything, i'd like input from you learned zopistas.

me:- i'm not a REAL programmer.  just a hobbyist.  some of my concerns
-will a level  2 da be sufficient for high write site?  i'm thinking of using
postgres
-if i were to retain  what zdiscssion has, willl it suffice to have just one
table?  i would like to tie this to AUTHENTICATED_USER.  so i want to use user
db as the authenticating agent.  is it advisable to just put the forum table in
the user db database?  
-how would you guys do the tree from sql?
-what other improvement can be included?  what pitfalls to avoid?
-anybody done this(zdiscussion/confera with sql backend) yet?

this is just a start.  i'm not sure whether i'll succeed.  but i'll die trying
:)

thanks.

Yes, that's because the split does something else. 
Don't know if you want to pursue this further, but if so, let's try and
track it down

How do you call it from dtml?
Have you tried it from outside the ZClass (in a test situation)?

If there is a traceback, it will show in the same way as normally, I
believe.

Hi,
OK, part of my zope pages are inserted from another site (like frames,

What must make my product is taking these external pages, treating the
HTML code and print it with some new features.
When the user clicks a link of this inserted page, I want to intercept
the request, treat the URL to go and searsh the HTML code to insert it
in my page.
Is it possible to do it???
How???

Thank you for your attention.

Is there any possibility to get some debbugging information to know

Is there any possibility to see from within python if the smbvalid

Is there any way to calculate a roles effective rights on a object in Zope?
I currently have the situation that I can access two DTML documents

Trying to track the problem down, but I dont get it right.

What about this acquire permission settings checkbox?
Is there any special behavior when I added a local role in a

Can this affect acquisition of permissions of e.g. the anonymous role?

Ah, so I understand that it's not called with arguments. So you need
another external method.
Change you external method to look like this

def recursiveMethod(obj, result):
     if hasattr(obj, 'aq_parent'):
          result.append(obj.title)
          recursiveMethod(obj.aq_parent, result)
     return result


def ParentList(self):
    obj=self
    return recursiveMethod(obj, [])

Then make you external method refer to ParentList
This works without arguments from a testfolder. It should work from a
ZClass as well, but I did not test that.

Facile !... (façon de parler...) Deux solutions ŕ deux problčmes différents :

1- Pour rediriger une page vers une autre, utiliser la syntaxe suivante :
<dtml-call "REQUEST.redirect (<url>)">
Dans ce cas, on n'a pas accčs au contenu html de la page.

2 - Pour avoir accčs au contenu HTML d'une page extérieure au site, il faut
utiliser la méthode externe suivante (trouvée dans un HowTo du site Zope, que
je sois pardonné pour l'emprunt sans mention de l'auteur....) :
import httplib

def GetURL(site, filename):
 from httplib import HTTP
 http = HTTP(site)
 http.putrequest('GET', filename)
 http.putheader('Accept', 'text/html')  # we can handle text/html
 http.putheader('Accept', 'text/plain')  # we can handle text/plain
 http.endheaders()
 httpcode, httpmsg, headers = http.getreply()  # get response headers
 if httpcode != 200:
  raise "Could not get document"  # HTTP error
 doc = http.getfile()
 data = doc.read()  # read file
 doc.close()
 return data

Ensuite, aprčs avoir inséré l'External Method dans la hierarchie de Zope, pour
récupérer le texte html d'une URL distante, utiliser la syntaxe suivante :
<dtml-let mapage="GetURL ('www.toto.com', '/index.html')">

    //    Traitements...

</dtml-let>


3- Pour accéder au contenu d'une page interne au site, utiliser une référence
du style :
<dtml-let mapage="_['page_a_traiter']">

</dtml-let>


Et voilŕ !...

This becomes very funny, it doesn't work. It still returns nothing.
Although I found a way to get this working, I would really like to know the
cause why it doesn't work. I'll try something different right away.

Hi Rik,

Forget my previous message, I got it working now with hasattr. I made a

Message-ID: <000901bf9afc$bc8da9e0$0200a8c0@digitalview.com.hk>

I'm trying to assign the string:

1=1

to the variable criteria using this construct:

<dtml-let criteria='1=1'>

but I can't because Zope complains:

invalid parameter: "=1'", for tag <dtml-let criteria='1=1'>, on line 5 of
Create_List

Some playing around reveals that it doesn't like spaces and the equals sign
(=) in the string.

Am I correct in thinking that something delimited by single quotes (eg.
'this is a string') is a string? If so why can't I (or how can I) include
spaces and the equal sign inside the string.


thanks

Hi

Try <dtml-let criteria="'1=1'">

The bit inside the double quotes is evaluated as a python expression, and
thus returns the string you want.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.10.html

Unlike other tags, the dtml-let tag is quote-sensitive, requiring that
attribute values are quoted. So in the above code, you're trying to
evaluate the expression "1=1", which isn't valid Python code (you're
trying to assign a value to a value). What you want is:

	<dtml-let criteria="'1=1'">

the roles given to the user in the sub-folder *replace* the roles
defined in higher folders, due to the way user folders work. the user in
the subfolder must have the same role as in higher folders (so he can
traverse the higher folders), plus any new roles in the subfolder.

jcNTUserFolder was developped because htrd's NT User Folder has not this
functionality, which I needed also.

Thanks.

After scouring through all the docs that I can lay my hands on I finally
found an implicit reference to the above usage of dtml-let in "HowTo:
Advanced DTML techniques".

<dtml-gripe>
One of the main stumbling blocks in getting to grips
with Zope is the incoherent documentation. The information
one needs is scattered about in countless docs so a lot of
the time will be spent searching those docs. This isn't helped
by the fact that the guides and how-to's themselves contain many
errors in the examples.
</dtml-gripe>

But many thanks to the kind people on this list who have responded swiftly
to my questions.

<dtml-let criteria=="'1=1'"> should work.

In dtml-let, you write one pair of quotes to specify that your're writing a
python expression. Inside quotes you're writing python.

Examples of valid python expressions:
   'this is a string'
   23
   methodname

You can wrap up any of the above inside a pair of double quotes and then use it
in <dtml-let>

DTML-LET sintax:<dtml-let variable="exp"> </dtml-let>

So use:
<dtml-let criteria="'1=1'">
not
<dtml-let criteria='1=1'>

Or te best way ( I've  found it yesterday) :

<dtml-let valueVar="'var has value: %s'  % (var)">


All the best!

Thanks for the tip with the Zope Quick Reference! It helps a lot.
In my specific case however, I still have a problem. It may be caused by
permission settings, but I don' really think so.

I have a folder "sample_images" in the ZClass "foo".

I in the "foo_add" method I try:

<dtml-call "manage_clone(sample_images,'my_images')">

in the "with"-section. Things like "manage_addFolder" work there.

The result is:
"The object sample_images does not support this operation. "

Suggestions?

Thanks! Joachim.

Take a look and let me know if this is what you were looking to build.

I will add that I too am not a "real" programmer and while I have 
been using Zope for months I am still just ramping up.

Windows 2000 professional is the equivalent of NT Workstation.
on Windows 2000 server, there is two way of managing the domain: the old
way (with pdc/bdc,etc.), and the new way, with active directory. in
native mode, pdc/bdc support is disabled and my code rely on it. you may
not be concerned by this 'problem' because nt 2000 pro (aka workstation)
can't manage a domain.

bizarre, it should work. are you sure that Benutzers can *view* sub
folders? where did you create the administrator role? in the top level
folder or in the sub folders?
by the way, where do your users authenticate from? from the nt 2k pro
box (that is, the users are created *on* this box)? from a different
domain (and the domain controller is another machine)? until I can write
a better doc, also read in the zope archives the messages from 'Ava' and
'minf7'

I'm not at the office right now, so I can't do further tests. but I
should be able to reply on monday, at least.

by the way, if you want to force all users to log in, you may consider
using zope with iis, and let iis do the authentication. this may not be
possible with nt 2k *pro* (it doesn't work with nt workstation because
IIS requires nt server).

You should try, instead :
<dtml-let criteria="'1=1'">

A string is an expression, and expressions must be enclosed in double-quotes...

If you really want all content served out of mysite, you might want to
look into the SiteAccess product.

If you want just http://localhost:8080/mysite, try BASE1.

BASEn starts from the root and adds an object (from the current
aquisition path) according to n- BASE0 = root, BASE5 = root + 5 objects. 
BASE == BASE0

URLn counts the other way, starting with the current aquisition path and
removing an object according to n- URL0 = current path, URL1 current
path - 1 object. 
URL == URL0

The Zope Quick Reference has this information.

Message-ID: <38E4A089.9533A493@rrsg.ee.uct.ac.za>

Hi,
Say I want to call a dtml method that requires some extra variable, one
way is to set that variable in the REQUEST using REQUEST.set('name',
'value'), and one is able to call the dtml method.
Somebody suggested using the DTML-let tag to do the same thing, but I
haven't been able to get it to work:

<dtml-let variable="some expresion">
 <dtml-var dtmlmethodname>
</dtml-let>

when dtmlmethodname tries to access "variable" with <dtml-var variable>,
zope complains that variable does not exist. Is there a way of using the
let tag to accomplish this, or is there a different way?
Is using the REQUEST object the normal way of "passing" variables to
other methods ?
thanks
Allen

Perhaps something very stupid I'm doing, but I've a strange result here.


I've a ZClass which has the properties 'Title', 'Issue', 'Comment'.
This ZClass automatically reindexes itself in catalog.

Now, when I change the contents of Issue, Comment and then search the
catalog for the specific ZClasses, I get all the created ZClass instances.

However, when I change the contents of the Title and I again search the
catalog for these ZClasses, I get all but the changed instance back!
However, looking inside the catalog, the ZClass is still there!

I forgot even to mention one thing!

Only when Title is empty it is returned by the catalog! Otherwise it's
excluded from the catalog result list.

Tom.

---

Perhaps something very stupid I'm doing, but I've a strange result here.


I've a ZClass which has the properties 'Title', 'Issue', 'Comment'.
This ZClass automatically reindexes itself in catalog.

Now, when I change the contents of Issue, Comment and then search the
catalog for the specific ZClasses, I get all the created ZClass instances.

However, when I change the contents of the Title and I again search the
catalog for these ZClasses, I get all but the changed instance back!
However, looking inside the catalog, the ZClass is still there!

Is this a naming conflict? Or is it something else?

The editonly properties howto involved some python code were too complex for

If I just use the manage method, it will re-direct me to the manage screen

Subject: [Zope] Variable as record type or dictionary
Message-ID: <NBBBINPMKCEPBDEGNIEOCEBIDBAA.jcoruna@umd.es>

Hi Zopists!

I need to copy a record from into a <dtml-in> tag to use it later.

Suppose:

"Client" is a select ZSQL method (select * from Client where <dtml-sqltest
client_num type=string>).
----
<dtml-in "Client(client_num='2345')">
  copy the retrieved record in a variable
</dtml-in>
----
"OrderLine" is a insert ZSQL method:

insert into OrderLine
  (order_num,client_num,client_name,client_address,...,product_num,...)
values
  (<dtml-sqlvar order_num type=string>,
   insert the column "client_num" from the previous retrieved Client record,
   insert the column "client_name" from the previous retrieved Client
record,
   insert the column "client_address" from the previous retrieved Client
record,
   ...,
   <dtml-sqlvar product_num type=string>,
   ...)
----
Registering the order lines...
<dtml-call "OrderLine(order_num='OR4567',product_num='PENCIL-0067')">
<dtml-call "OrderLine(order_num='OR4568',product_num='PEN-BLUE-8')">
<dtml-call "OrderLine(order_num='OR4569',product_num='PENCIL-0045')">
<dtml-call "OrderLine(order_num='OR4570',product_num='PENCIL-0023')">
<dtml-call "OrderLine(order_num='OR4571',product_num='PEN-BLCK-1')">
<dtml-call "OrderLine(order_num='OR4572',product_num='PEN-031')">

----

Take in mind that I can't put the ZSQL method "Client" inside the ZSQL
method "OrderLine" because the Client method needs about 10 seconds to
execute and if every "OrderLine" method needs his time plus 10 seconds (from
the "Client" method) this can take over one minute for the above example
order. This is not viable! Awaiting 15 seconds to place the order is
acceptable but over one minute isn't.

The solution is to execute the "Client" method only one time. Any ideas how
can I copy the Client record?

Subject: [Zope] DST Zone Date, help needed!
Message-ID: <20000331145302.10067.qmail@hotmail.com>

Hello all,

I'm having a hard time with dates since portugal entered DST last March 26.

If I use:

<dtml-var "REQUEST.set('mydate','2000/03/31 15:00:00.000 GMT')">
manage_changeProperties(REQUEST)

I can get from "mydate" the utc hour (14:00) with the
fmt="a-la-C %H:%M" and the current GMT DST of Portugal(15:00) with
Zope's TimeMinutes().

If I use:

<form action="manage_changeProperties">
<input type="text:date" value="2000/03/31 15:00:00.000 GMT" name=mydate>
<input type=submit>
</form>

the fmt format and zope's zopetime() give me the same hour that
is the GMT-DST (15:00), i.e, somehow the "text:date" conversion is
ignoring the Portuguese GMT-DST and assume, in this example, 15:00 as
the UTC.

Since nobody is answering I'm going into the source to find where is this 
conversion. I'll get back with a solution... I hope :-)

Thanx,
Julio

Hi All.

and I have set the permissions exactly alike. Rendering the one class is
ok for non-super-users, but rendering the other one gives this:

It worked fine and give no special problem.

I have tried to update to the version 2.1.2 (RPMs) using Apache + pcgi.
Every time I try to use the zsql methods, zoe dies.

I have tried the latest version 2.1.6 (tgz). In this case I receive

Any suggestion ?

Can you not achieve the same thing with a single user folder in the

That's how I use NTUserFolder.

If you are fiddling with the setup of your pages you should do this

I briefly looked at the list's archive but did not find the actual answer.

2- Is there a way to purge the ZODB object history (ie. not the cache but the

The short answer is yes.

But your performance varies depending on how deep you want
to get into the subject. The most simple way to run Perl
CGI is:

(1) Use a Python external method to handle all CGI request.
    Let's call it "cgi_bin".

(2) Your CGI URL requests would be something like:
    http://www.mysite.com/cgi_bin?cgi=mycgi.pl&arg1=var2&arg2=var2

(3) Inside your external method, you check the values of
    REQUEST.cgi, REQUEST.arg1, REQUEST.arg2 and use Python
    pipe commands to launch the Perl interpreters and capture
    the output. (On Windows, use functions from the win32pipe
    module in Python's Win32 extensions.)

There was some discussion on all this about a week ago. Please
read the thread "newbie CGI question":

http://www.egroups.com/group/zope/showthread.html?start=26666

If you don't like the look of the URL, you can still use
Zope's SiteAccess product to tweak and interprete a URL like
htpp://www.mysite.com/cgi-bin/mycgi.pl?arg1=var1&arg2=var2

But in order to achieve decent response time, you will have to use
Apache + mod_rewrite + mod_perl + Zope. Which is more involved.

Hi again,

after read the mail I thought it could be misunderstood.

What DateTime returns wrong is the "GMT" part of, for instance,
"2000/03/31 18:08:58.3851 GMT".

It should return, "2000/03/31 18:08:58.3851 GMT+1".

Note: the hour is correct, but the gmt part no, should be added "+1".

Onderwerp: [Zope] Only allowing authenticated users to view document


I have a dtml-document which I wish to be viewed only by (certain)
authenticated
users.  I tried un-checking all the security permissions and the acquire
permissions boxes, but I can still access the method.
[cb] I guess you have the permission to view the rendered document as
manager
 Putting a
<dtml-var AUTHENTICATED_USER> in the form shows nothing when I test it (and
not
anonymous as I thought it would).

AUTHENTICATED_USER is an object , the html source of  your rendered document
will show its id
try: "AUTHENTICATED_USER.getUserName()" (with quotes) in your dtml-var tag,
which is a string representing the name of the authenticated user (or
'anonymous').

cb

El castellano tambien funciona aqui. ;) Podrias dar mas
detalles del mensaje de error? Asegurate de que el
duenno de las carpetas sea "nobody", para que no haya
problemas durante el proceso de makefile.

Could you provide the error message itself? Make sure that
the owner of folders are "nobody". (Usually I am lazy
and change myself to superuser, and then change everything
recursively into nobody.nobody for owner.group)

The owner:group of all folders is nobody.

The system is: 

	RedHat 6.1
	ZOPE 2.1.6
	Python 1.5 

i don't know what more tell you about the error.

We too have seen more frequent restarts centered around /manage
activity.  I have one user that I can tell when he starts working in the
morning by the first Zope restart of the day.  We have not been able to
get a consistent repeat of the behavior though.

We have three servers running with one taking most /manage activity and
that machine is the one that restarts the most.

>i don't know what more tell you about the error.

In case you have not realized, what you have provided is NOT
an error message. I don't know why you call it an error message.
That is why I asked you to provide the error message. :)
If you have an error message, please provide it. If not,
please don't call something an error message when it is NOT.

Por Dios, si no hay error, para que me asustas? :)

Please read the README.txt file and follow the steps there.

(1) First check your environmental variable is properly
    pointed. Do

    echo $SYBASE

    if it does not show the directory of installation of your
    Sybase database, you are in bad shape. You need to set this
    environment variable, preferable from the moment you reboot
    the machine, but if not, from your Zope's "start" file.

          SYBASE=/mnt/sybase1192
          export SYBASE

(2) Follow the instructions in README.txt

    cp Setup.linux Setup
    make -f Makefile.pre.in boot
    make
    cp sy_occ.so ..

Then it'll work.

(Me parece que tu problema no es Sybase adapter, tu
problema puede ser Unix/Linux. Parece que no eres
familiar con Unix/Linux.)

All,

Has anyone used Andrew Kuchling's Oedipus package (parses and displays
ODP data from dmoz.org) with Zope ?
In the Oedipus 0.0.7 distribution there is a .gz file with what looks
like a Zope product distribution.
But unpacking it in the usual place for zope products doesn't make it
visible in my Zope Products folder.
I am using Linux RH 6.1, Zope v 2.1.6, Oedipus v 0.07.
Any known problems ?  Do I need to have XMLDocument imported before
Oedipus will import ?

Help !

Hi,

How do I store an object in RAM during Zope's up-time?

I don't want to store it as a persistent object.
And I don't want it to disappear after a http transaction
(so REQUEST variable is no good.)

I would like to be able to create this object given
a particular http transaction, and afterward I may
want to modify it. This is a bit like session management
data, but it's a piece of data that is shared by all
sessions...

regards,

Hung Jung

None other than to check the Zope-ptk archives for info, I haven't used
it yet myself.

As far as I know there is not currently any such mechanism.  I wonder
if the PTK people have thought about this?  I haven't gotten around
to signing on to the PTK list yet, but I really need to.

Go to database management on the control panel, and compress your
database.  This will delete old transactions up to whatever point
you tell it, thus shrinking the database.  It won't have any affect
on rendering speed, though; from what I understand ZODB is designed
to keep read performance high regardless of the number of transactions
recorded in the database.

I read you could define a ZClass instance's method as a field-index of a
ZCatalog; but it's not working for me.

The DTML method dept_code is simply:

  <dtml-return "_.string.split(jobcode,'-')[0]">

When I call the method directly it returns a single character, the first
character of the jobcode.

The method dept_code is defined as a field-index of the ZCatalog JobsCat.
But when I access JobsCat thus:

 <dtml-in "JobsCat(meta_type='Job Opening', sort_on='dept_code')">
   <li>
   <a href="<dtml-var "JobsCat.getpath(data_record_id_)">">
            (<dtml-var dept_code>) <dtml-var jobcode>: <dtml-var title></a>
 </dtml-in>

the items are not sorted, and dept_code is null.

Can anyone see what I'm doing wrong?

Hi Tino

A lot of my pages are served by sqlsession, and sometimes I have to do
maintenance on the sql tables, and take down the database server.

Hmm, here is what I have, in DTML Method aaabbbccc::

 <dtml-var standard_html_header>

 <p> Calling asdf with variable 'foo' = 'bar', using the let tag: </p>

 <dtml-let foo="'bar'">
   <dtml-var asdf>
 </dtml-let>

 <dtml-var standard_html_footer>

And in DTML Method asdf::

  <p> <dtml-var foo></p>

When I view aaabbbccc, I see::

 Calling asdf with variable 'foo' = 'bar', using the let tag: 

 bar

which is exactly what I expected.

Can you see any differences between your code and mine?

Subject: [Zope] REQUEST weirdness . . .
Message-ID: <38E534D6.133329E4@globalcrossing.com>

'ello.

Bear with me on this one; I'm having worlds of problems coming up
with any kind of coherent way of expressing the problem. :)

I have a form which contains the following:

<input type=text name="street.address1:record">
<input type=text name="street.address2:record">
<input type=text name="street.city:record">
<input type=text name="street.state:record">
<input type=text name="street.zip:record">

To parse this data, I would ordinarily just use a dtml-with:

<dtml-with street>
  <dtml-var address1>, etc, etc, etc
</dtml-with>

No problem.  This, however, is where things get interesting.
I'm passing the data from this form to a "confirmation"
page.  The data from the first form will be simply put into a bunch
of "hidden" fields, where the user will be prompted to REALLY do what
they were doing, or cancel back to the original form.

Now, I don't want to have to re-code the confirmation page every
time I add a new value to the main form, or remove an input for
whatever reason.  What I figured I would do is the following:

<dtml-in "REQUEST.form.keys()">
  <input type=hidden
         name="<dtml-var sequence-item>"
         value="<dtml-var "REQUEST.form[_['sequence-item']]">">
</dtml-in>

This works fine for all the values in the form which aren't using
the ":record" tag, but obviously for my address, I'll 
need to iterate through it.  ie:

<dtml-in "REQUEST.form['street'].keys()">
  <input type=hidden
         name="street.<dtml-var sequence-item>:record"
         value="<dtml-var "REQUEST.form['street'][_['sequence-item']]">">
</dtml-in>

( In the original code, "street" wasn't hardcoded, and I just wrapped
  that statement around a dtml-try, where the except clause was my
  original dtml-in. )

This code doesn't work.  Upon closer inspection, the following line
was the culprit:

  <dtml-in "REQUEST.form['street'].keys()">

Upon even closer inspection, *none* of the dictionary functions would
work.  Not even <dtml-var "REQUEST.form['street']['address1']">

Then I decided it was time to just see exactly what was in the object.
<dtml-var "REQUEST.form['street']"> yielded the following results
(I had just entered sequential numbers for all five inputs):

address1: 1, address2: 2, city: 3, state: 4, zip: 5

Here's the output of <dtml-var "REQUEST.form">:

{'street': address1: 1, address2: 2, city: 3, state: 4, zip: 5, 'submit':
'submit'}

The original <dtml-with> code still works, as does
<dtml-var "street.address1">.  I've also tried using getitem:

<dtml-var "_.getitem('street')['address1']">

I'm quite confused.  It would appear that "street" really *isn't*
a dictionary at all, yet somehow the <dtml-xxx> tags still work.  What's
going on here?  I'm quite befuddled.

Thanks a lot in advance for any help, and apologies again for the
convoluted message.

Message-ID: <Z4C$7kAIdS54EwQ+@compkarori.com>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Hi,

I previously posted that I was having problems with Zope and Interbase
losing the ODBC connection ( on Win32 ).  This would happen whenever I
entered the web management interface, and at other times when I could
not identify a cause.  I then had to shut Zope down and restart it.
Zope would not allow the ODBC connection to be made otherwise.

I was using the much older Visigenic driver because the Intersolv driver
truncated varchar fields (a known bug).

However, recently I joined the Interbase mailing list, and one of the
Interbase staffers suggested I retry the Intersolv driver and recast the
varchar field as char to work round the truncation

viz. select cast(myvarchar as char(n)) as myvarchar from foo;

I am pleased to report that this works well, and over the last few days
I have not observed a single disconnection.

Furthermore, I have noticed that the very first use of the OBDC
connection after Zope started always gave an error.  This problem has
also now disappeared.

For interest, my experimental server is using a PII 300 overclocked to
450, 128Mb ram, NT4 server, and an IDE hard drive served on an ADSL
connection.  There are about 20,000 items in the ecommerce database.  I
am also using Interbase to do Zope session management.

You can reach the server by using the url below ( a PHP script on my
static server redirects to the ADSL box).

I'll post an update if the situation changes.

In addition, Interbase Corp has expressed an interest in supporting Zope
by helping/writing native drivers for Linux and other platforms which
are supported by the new Open Source Interbase 6.0

I know that in the CVS now, record objects support the Python mapping
interface (which is what you're trying to do) but before that, and I
think this is the case for the 2.1.x branch, this wasn't supported, and
you needed to access the object by attribute only.  This makes what you
want to do in DTML pretty impossible (but not impossible from python).

I guess you can try waiting for the next main trunk release, or you can
modify your record objects to support a mapping interface just like the
CVS does.  It's a very simple class in the
lib/python/ZPublisher/HTTPRequest.py module.  This is probably the
simplest solution to your problem.

Nope.  In your case it's an object with _instance attributes_ that
contain your values.

Hi there,

For some reason Zope would suddenly hang and it's thread would consume 99.9% of CPU usage.  The first time this happened the problem magically disappeared after a complete reinstall. Here's what happened while casually throwing bannerexchange code into the default DTML document.

standard_html_footer

   </tr>
  </table>
  <dtml-var bannerexchange>
  </body>
 </html>

bannerexchange

 <h2><dtml-var title_or_id></h2>
 <p>
 <!-- bannerexchange code -->

I'm on Zope 2.1.6, do future version prevent me from making accidental infinite loops like this?

Message-ID: <38BC6ED7.94F2BCBC@aHIT.de>

Hi,

I created a POIDocumentClass (ZClass based on DTML Document; meta type
PIO Document) .
Than I created an instance of this POIDocumentClass id 'MyDoc' title 'My
Document'.

Now when I try to find all POIDocumentClass instances in a Folder I do
the following:

<dtml-with aq_parent>
<!--#in "objectItems(['POI Document','DTML Document'])"-->
  <!--#if
"AUTHENTICATED_USER.has_permission('View',_.getitem('id',1))"-->
      <a href="<!--#var "absolute_url()"-->"><!--#var title--></a><BR>
   <!--#/if-->
<!--#/in-->
</dtml-with> 

I get back the right title 'My Document' but absolute_url() returns
http://myserver:8080/foo/%3cstring%3e instead of
http://myserver:8080/foo/MyDoc

When I create a DTML Document instance within the same Folder
absolute_url() works fine.
I suspect there is something wrong with my POIDocumentClass :-(
Can anybody please explain this behaviour ?

I created a ZClass based upon DTMLDocument.I wanted to have

So I decided NOT to derive my class from ObjectManager.
 
Now when I create an instance of my new class within a Folder 
the instance has no id !

I think this is not a feature ;-)

Okay.  Perhaps someone else on the list can answer this one then: I
have a standard Debian install of Zope.  ZServer works fine.  Apache
works fine.  Zope shows up fine in apache.  Except... I can't log in. 
At all.  With any username.  What do I have to do to get Apache to
recognize Zope's authentication?

Don't forget that you can also download Zope and try it out easily. I'm
running it on Win32 for some development tasks, and it did not take much
effort at all to install it and run it locally. So, if you want to continue
playing you can always do that.

In terms of popularity and being supported for a long time, I do believe
that DC has been quite successful in their consulting business, so they'll
be around. And, Zope itself is open source, so there will always be avenues
available for using it.

IMHO, you'll be quite happy wiht what you can do when you migrate those apps
to Zope. In the meantime, though, you can continue using them by setting up
Apache with rewrite rules that allow you to access those CGIs still. Without
knowing anything about your app, it's difficult to state how you would
"interface" with them. There are avenues for doing so. A pretty
straightforward one might be XML-RPC. (Your perl CGIs could access Zope data
via XML-RPC.)

I think Zope is pretty stable (and I think most regular users of it would
agree). It's not generally more likely to die than your system itself. If
you do "low-level" development on a different machine, your database should
be OK. Plus, all you need to do is back up your Data.fs file. If something
got really messed up, you just drop in the back up file.

I think the answer to "what if Zope goes down" is really the same kind of
thing as "what if the server goes down?" or "what if the drive crashes?"

If you really want, there is a Zope product that will mirror your site in
HTML (and others have used wget to mirror the site in HTML). But, I think
it's better to just maintain a solid Zope, because your site quickly goes
from being a static HTML thing to being a dynamically produced, interactive
thing which can't be reasonably represented by HTML.

People on this list have done benchmarks using ab and other tools. I think
the general consensus was that with a moderate machine and a moderately
dynamic app you can do a million hits+ per day. Through more machine at it,
or go for ZEO (which lets you mirror the object database on multiple
machines) and you can handle lots and lots of traffic.

Our site (Byproducts.com) has been running on Zope since last May. I've had
very little downtime and I don't think I would blame any of it on Zope.

Still much to learn.

I'm trying to write code to display a tree where different
kinds of node require different display action.  Each node has a
property (possibly acquired) "kind".  For nodes which reach
the innermost <dtml-else> in the code below I want the dtml
content rendered.  How can I do this?  If i refer in
some way to PARENTS[0] then id goes up with it.

Please, please, please, what expression will work here
to get the content of "id" rendered?

Code follows
------------
<dtml-tree expr="lists" branches=objectValues sort=order>

        <dtml-if "meta_type=='Folder'">
            <dtml-var title_or_id>
        <dtml-else>
            <dtml-if "kind=='discussion'">          
                    <A HREF="<dtml-var listURL>">

Just to follow up to myself so you know: I have seen snippets about
RewriteRules all over the place for using Apache with Zope...

I have tried everything i've found, and nothing has worked so far. 
(The RewriteRules appear to do nothing at all...)

Lot's not there. The only ones that show are those that use Zope built-in
ZServer. If your Zope is hidden behind a different web server and that
webserver's ID string hasn't been changed to mention Zope, then your site
doesn't show. Anyway none of my sites show up on the Netcraft list.

This is from the "Other Uses" page, right?  In that example, it is an error
to access the folder, since it is only meant to act as a placeholder for a
session value.  The IndexError occurs when the code tries to access the last
element in the remaining path, but there *is* no remaining path!

Access Rules execute before any authentication takes place, so
AUTHENTICATED_USER doesn't exist yet.  This also prevents them from
accessing any other Zope objects unless you give the Rule a Proxy role.

It looks like you need GenericUserFolder or UserDB.

Message-ID: <010401bf831d$2f850440$6e00a8c0@redindustries.com>

(short time reader, first time poster)

So I've set up my zope installation to test it out for use as the intranet
server and content management system for my company. One of the features
that I intend to use heavily is the FTP access, the main users of the system
will be designers and their clients, so I want to set up an interface that
works with existing tools <DTML-rah-rah yeah>.

However everytime I connect with ftp (used Dreamweaver's FTP client as well
as EMACS) I get an "PROBLEM(100) ZServer unhandled connect event" error from
Zope. I've just upgraded to 2.1.4 which solved the crashing problem for the
most part.

My question is what is an "unhandled connect event", can I make a connect
event be handled? Is there a howto, a document or a previous thread on this
subject?

Help, I want to be a fanatic!

Right.

Yes.  One thread will win, and one thread will loose.  The winner will
get the new id.  The looser will try again.  The looser will find out
when it tries again the the id it wants is taken, and will report that
to the user.  The user picks another id.

No, but a programatic resolution protocol is planned for future releases
of ZODB.

The chances of colision are very small unless you have an incredibly
write intensive application (which is not ideal for ZODB filestorage. 
In that case, you should store your information in a RDBMS).  This the
"optimism" in optimistic.

WU IMAP on a RH 6.x box is *bizarre*.,

Ok, I kicked this off before dinner, having added some debugging output to
imaplib.py.  When I came back, there was a TON of it dumped across the console
at which I was running Zope, but no mail.  Basically, it had walked down through
all the .gnome/* directories, sucking up bitmaps, retular files, subdirectories,
everything (ICK!).

Maybe we need to add a property to the WorldPilot object which lets you
configure the folder passed to the initial list() call (e.g., to be something
like "~/Mail").  This parameter would default to the empty string, so that the
Cyrus clients would continue to operate as before.  I'll see if I can't come up
with some kind of patch.

My sarcasm meter is in the shop after an accidental exposure to
comp.lang.perl.misc (ugly story, don't ask), so I'm not sure how big a brick of
salt to apply.  WU IMAP is a nice stick for clobbering those who think Zope's
documentation stinks;  there is absolutely *nothing* in the package to give the
hapluse admin any clue how to configure the damn thing.

I spent about 4 hours this weekend prowling the net looking to resolve this
issue.

Hi Tres,
This was written up last week and after a little digging on egroups (I thought I
had saved that message) I finally found it. Jo Meder provided the following
information

<quote>
Chances are, that the request to "LIST *" in directory "" that 
imaplib issues cause your imapd to begin scanning your whole home 
directory which can be a lot of data, as we all know.

I worked around this problem by creating /etc/c-client.cf with the
following contents (the first line is required by imapd, otherwise
the file is not accepted):

--------------------------------------cut here -------------------
I accept the risk for IMAP toolkit 4.1.
set black-box-directory /var/spool/imap_folderlinks/
--------------------------------------cut here -------------------

I then created /var/spool/imap_folderlinks and symlinked the
directory in which my mailbox folders reside to 
/var/spool/imap_folderlinks/jo

Repeat for all users on the system and set permissions appropriately.



        Jo.
</quote>

Also some information on this can be found in the file imaprc.txt that should
be in /usr/doc/ or where ever RH dumps it. (I'm running this on SuSE myself.) I
have tried this fix but I probably will.

Subject: [Zope] RE: Different Login Screens for Management and User?
Message-ID: <38BCA9A0.C5CEA34@cs.rutgers.edu>

I was working on the same kind of problem (see my earlier post today),
and I think
I found some solution, thanks to the many hints here and in the zope-ptk
list. It's
actually quite simple.

The trick is to play with exceptions. In your standard_html_header,
include something
like (replace 'Member' with the role you want):
<dtml-unless "AUTHENTICATED_USER.has_role('Member')">
   <dtml-raise type="Please Login!">
                <p>Please login before entering!<p>
   </dtml-raise>
</dtml-unless>

When the error is raised, the standard_error_message is called, so from
there,
you can do some more tests and go to the appropriate login page. I have
not
fully tested this yet, but I think it should work. I think if you put
type=Unauthorized in the dtml-raise tag, you should get the usual HTML
login instead of the error.

Anyone has a better (more elegant/original/creative) solution?

I get this exact same problem trying to add completely normal File Objects
to my Zope site.
I can create the object empty if I don't include an upload, but the instant 
I try and upload anything it dies with the above error.
It happens _constantly_ for me, not just time to time.

Thank you. This 'patch' did in fact work although the problem was in fact more
subtle than originally described - the 'unhandled' type error only
arose if I used joins in the select part of the statement.

Message-ID: <20000301011319.A10204@devware.com>

So, if I am grokking the whole zope thang properly here, then
theoretically, when I imbed objects within my zope documents, I
shouldn't hardcode in specific urls to them.  Instead, I should treat
them almost as if they are always in the current directory, even if
they are a couple of folders up.  This way, if I want to override some
behavior in the future, I just copy the object down into the current
folder and edit it.  I notice however, that if I do this, it plays
hell with browser caching because the browser winds up pulling things
from different places all the time even if it's actually winding up
pulling the same document down.  How do other people deal with this?

Hi Lucas,

I am the original author of zGold, and I'd like to explain where it came
from and what happened to it subsequently.

zGold was originally written as an exercise of learning and also as an
example site for a conference/exhibition here in the UK.

At creation time there was no intention of releasing it to the public at
large.  It was however made available purely as a 'teaching aid'.

Subsequently it was proved that there was a serious security hole in it that
allowed users to see the clear-text passwords/usernames of other users.

Also since this was created in my 'spare time', I have had no further time
to allocate to it and it has sort of died of neglect.

That being said, I still have the original tarball hanging around and anyone
who wants it can mail me and I'll get it sent out.

caveat:
zGold is not supported in anyway and is not 'production' ready.  Use it at
your own risk.  I will not be liable/responsible for any/all problems it may
cause.

Thanks for listening.

I want to import a static HTML web site (about 10 directories,

But I couln't find any documentation about it.

Ok, I found load_site.py
 ./load_site.py [options] url file .....    

 But:
 	Which 'url' should I pass here?
 	Does 'file' mean that I only can import one file an not a 
		whole directory tree?
 
Where can I find more information?

Thank you
Veikko

Howdy all.  Please note that "More" under "Zope News" has the old style
display.

Question: do you think we should have a knob available for members that
lets them toggle the home page between old style and new style?

Message-ID: <200003011127.VAA65638@mail.theinternet.com.au>

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

Hmm .. this sounds really weird. 

In my case I observed the following.

Structure:

/
  +Intermobil
    +daten (up-/download section with form for upload, dtml-methods,
external methods etc)
       +category1
       +category2
       +... (sub- and subsubfolders for storing the files)

testfile is a Winzip/Zip file (1.129 KB), uploading it gives the error.

I created a test folder somewhere else and pasted the content of the
daten folder (without category subfolders), tried to upload my zip file
there .. and -voila- it worked.

Then I changed the upload method in my test folder by inserting a
<dtml-with "Intermobil.daten"> in order to redirect the upload into a
category subfolder of the original daten folder .. and -surprisingly for
me- the upload of the test file worked, too.

I deleted the file, went back to daten, tried again and got the same
error as before.

So here I'm really confused, cause I don't know where to look and what
exactly could have caused this problem.

Thanks for bringing up this to the list again,
Thomas

Howdy all.  Please note that "More" under "Zope News" has the old style
display.

Question: do you think we should have a knob available for members that
lets them toggle the home page between old style and new style?

Message-ID: <38BD079B.3F5D35D5@imeme.net>

Zopistas,

I'm setting up zope on a linux box with support for large files.
(>2gb).  I need to make sure that the ZODB will continue to work
properly past this point.  Is the filesystem stuff the ZODB does handled
by python or ZODB?

If the answer is ZODB, where can I look for fs calls to make sure
they're 64 bit?

Thanks,

   It is an URL to a Zope folder. If, for example, you've installed Zope on
http://my.server/path/to/Zope/, and you want to upload your site into
http://my.server/path/to/Zope/virtual/site (the folder /virtual/site should
be created before using load_site.py), the URL will be just
http://my.server/path/to/Zope/virtual/site

   The file can be a file, or a directory, or a list of files and
directories...

Use the absolute_url() method on the objects. 

That way, your generated HTML will contain absolute URLs to the objects,
that are the same across different Folders in your site even when the
object is acquired from elsewhere. Overriding as you described will
still work the same, the URLs will reflect the change accordingly.

Syntax variations (as always from the top of my head, not tested, YMMV):

  <dtml-var "object.absolute_url()">
  <dtml-var object url>
  &dtml.url-object;

The last notation is especially useful in HTML tag attributes, as it
won't break WYSIWYG HTML editors:

  <a href="&dtml.url-object;">Go to object</a>

Brian,

I think it's a permissions thing with tinytable. There's a permission called
something like 'access tinytable contents' which you need to give to the
anonymous user in the squishdot folder.

Well, that's how I cracked it, anyway...

cheers,

Chris

Hello there,

we got a site up and running (its actually a shop solution based on
zope).
Platform is NT, zope version is 2.1.4.

Most of the time, the site is running very fast. But some times it
hangs.
It does not use much processor-time at this moment (arount 14%) but
it does not process any requests for some seconds.
Its very annoying. Does anyone know how to avoid such behavior?

thanks. I've imported the data now. 

with
python ./load_site.py -D  -u superuser:pwd http://host:8080/ directory

There are 2 problems now:

1) HTML character references are only imported within quotes.
The line 
	<a href="#Einf&uuml;hrung">Einf&uuml;hrung</a>
is imported as
	<A href="#Einf&uuml;hrung">Einfhrung</A>

and 
Transportmittel unerl&auml;&szlig;lich.
is imported as
Transportmittel unerllich.	


2) file names are used as the DTML document Id e.g. index.html
It seems to me, that index_html is the default DTML document within a
Zope directory.
Can or should I change it to index.html? And where?


Thanks
Veikko

What is required to get ODBC under UNIX functioning using e.g. the iODBC 
drivers?

Is it just a matter of pulling down the winODBC driver and making it work,
or is there some devil magic required (i.e. do I have to commit weeks, 
rather than days to it). 

I do have a black robe, plenty of chickens, and a goat.

What optimization do you have NT set for?

File Serving, Network processes, or local use?

By default NT optimization is set for file serving. This means that if some one is making heavy use of the file serving cpabilities
of the machine it gives less time to network processes like zope.

   Looks like a bug in HTML parsing. There is no simple solution for this.
When I got some free time (and it shouldn't be in the nearest future) I'll
add additional processing into the parser in load_site.py.

   You don't need to. Just create DTML Methtod index_html and put
<dtml-var index.html> in it. That's all.

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.

The how-to list is a bit daunting; also I get the feeling that
there's a level of jargon necessary just to figure out what 
documentation to read.  I don't have that, so I haven't found
what I'm looking for.

Is there anything like what I'm looking for?

But, on the other hand, there is not much file-serving at all from this
machine.
I only use it to transfer log-file or such.
All other communication is over Zope only.

It appears to me it could be some dead-lock situation inside Zope or
medusa.

Subject: [Zope] Best way to run Zope for hosting apps by multiple developers?
Message-ID: <000901bf8398$f3019ca0$24886883@uoguelph.ca>

Hi,

The University of Guelph is looking at making Zope hosting available
to our departments and organisations. Because we want to be able to
use MS Access databases, we propose to run Zope on NT (so that we can
use Z ODBC). In essence, we're looking at using Zope within an ISP
hosting model, where we will provide the infrastructure and our
clients will do their own development.

I'm trying understand how to design a Zope system to achieve two
things: 1, make it less likely that a poorly written app will
compromise the service for other developers, and 2, establish a test
environment where applications can be debugged, and then moved to a
production server.

I have two questions:

1.
I've read the FAQ for ISP's, and I've seen references in the
documentation to ways of configuring a system so that Zope so that
each client gets their own instance of Zope. This would presumably
help to insulate one Zope app from another. However, I can't find any
details about how that's done... can anyone point me to more info?

2.
Given developers with administrative control of their own folders on
two Zope servers (test and production), how can I make it possible for
them to take a test application (consisting of a set of Zope objects,
let's say within one Zope folder object), and move it to a production
Zope server. I can do this by exporting from one Zope server and
importing into another, but this involves giving the developers access
to the file system (they must place their exported object in the
"import" directory on the target Zope server), and all developers will
be dropping their objects in the same place. It's not elegant, and I
can foresee various management problems and security risks arising
from it. Are there other ways to migrate a Zope application from one
Zope server to another?

Thanks in advance for any pointers,

Nick Dobbing.

Hi:

I've been using DTML successfully to generate around 20+ reports outside
of zope itself.  The result come back from the DB as a pdf document.  The
solution has worked well.

It looks like there might possibly be a bug in the dtml totalling process,
however, when dealing with larger numbers.  The results on one report are
accurate for a 20 row table with smaller totals (say, e.g., 51518), but
the larger totals are incorrect (e.g., it reports a number say in the
300,000 range rather than 1,378,835).  The DTML for that column (the TOTAL
column) is: 

<!--#var total-TOTAL fmt="%15d"-->

Has anyone else seen this? The version of DTML I'm using is from the last
quarter or so of last year.  Any ideas?

All - Have a problem which I am certain many of you have already
encountered.

With most web servers, you can create specific web server instances that
listen to virtual network interfaces on the server (virtual IP addresses).
For example, I can have multiple httpd instances, with httpd1 listening to
192.168.1.101 and httpd2 listening to 192.168.1.102 on a box where the
physical IP address is 192.168.1.100.  This is configurable within the web
server.

I want to be able to have Zope listen to a specific network interface, i.e.
- a virtual IP address that has been created on the server.  This will allow
me to have multiple Zope sites running on the same machine.  How can this be
accomplished?  Any/all suggestions are greatly appreciated.

Thanks,
-Brian

You could run Zopes behind an Apache server and connect via ProxyPass or 
FastCGI. This would even allow virtual servers on one IP address.

I will be roasted -- I thought I'd followed these directions already, and still
had it hang.  When I went back to try again, I discovered that the symlinks were
screwy (how imapd found my home directory at all is a good question).  When I
clean them up, it works!

Hmmm, /usr/doc/imap-4.5 has only a README file, which doesn't mention the
/etc/c-client.cfg file at all (it talks about building the package, and setting
up the /etc/services and /etc/inetd.conf files to make IMAP work).  Thanks very
much for reposting those directions!

Message-ID: <200003011733.SAA13630@rztsun.rz.tu-harburg.de>

Am I the only one whose bobo_modification_time started today with
/2000/2/29 instead of /2000/03/01?

I create a new method Time_now:

<dtml-var ZopeTime><br>
<dtml-var bobobase_modification_time-->

and the Output is:

2000/03/01 18:30:21.091 GMT+1
2000/02/29 18:30:5.198 GMT+1 

Same appears in my Undo Log (February, 29th started again today) and so
on.

TIA,
Thomas

IMHO this is not necessary:

just use versions for your developpment work, then commit your version 
when it's done.

If you want to stick with Basic HTTP Authentication, the key is to persuade
Apache to pass that info through.  On my setup, this involves adding the
following to the "RewriteRule" line:

 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

Also, the "RewriteCond %{HTTP:Authorization} ^(.*)" line has to be repeated
before *each* rule to which you want it to apply.

Hi everyone,

I've grepped through the source and consulted the ZQR, but I still haven't
figured out how to use bobobase_modification_time. I've got a directory
with a file object, and I'd like index_html to display when that file
object was last modified. I've tried all manner of syntax combinations,
but I can't get it to refer to the modification time of a given object and
not just the modification time of index_html. Suggestions?

-Tim

Subject: [Zope] Dealing with Dictionaries
Message-ID: <4.2.2.20000301125741.00b6b100@saladin.aisys.com>

I have a DTML method from which I want to answer a dictionary.  It looks 
something like this:

<dtml-return "{'foo':'bar', 'biff':'boom'}">

I want to be able to use this information in two different ways.  First, I 
want to be able to get a list of keys from the dictionary.  Second, I want 
to be able to get a list of values.  I could easily do this in Python, but 
I'm sure there must be a simple way to do this in DTML.  I tried something 
like:

<dtml-return "_['dictionaryVariableName'].keys()">

but that didn't work.  I did notice that if I just used 
"_['dictionaryVariableName']" I actually got the keys.

Basically I'm trying to create a system by which a user can enter a full 
string and an abbreviation for the string.  I want to be able to produce a 
list of the full strings, and I want to be able to produce a list of the 
abbreviations.

Any help would be appreciated.

Thanks.

The ZODB uses a "pluggable" Storage-derived object to do the actual reads/writes
(this is where Ty Sarna's BSDDB Storage gets plugged in).  The "standard"
Storage is the FileStorage, defined in
$ZOPE_HOME/lib/python/ZODB/FileStorage.py.

   Frank, I agree, however I probably should have been more specific.  I
would like to be able to do this using ZServer rather than using Apache or
in my case Netscape Enterprise Server.  Do you know if ZServer supports
this?

Use the source. :)

From z2.py:

  -a ipaddress
    The IP address to listen on.  If this is an empty string
    (e.g. -a ''), then all addresses on the machine are used. The
    default is %(IP_ADDRESS)s.

so in your start script, add: -a xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is the IP address you want to hook to.

Cheers

Bill

1: What is your timezone setting. It could be that dates are displayed in a
different timezone.

2: If you do your test from a DTML Method, you'll be shown the modification
date of the container it is called on. For an explanation, see:

I think I found the problem, at least for my purposes. :)  I'm not sure
if this has already been corrected in the latest versions of DTML or not
but it might be worth a check.

DT_InSV.py line 239 was:
  s=item*item

Instead, I'm now using:
  if type(item)==type(1): s=item*long(item)
  else: s=item*item

Looks like this information is needed to calculate some of the other
statistics and when the item is a large integer it will cause an
exception.  The exception is then caught and results in that item
be omitted from some calculations, such as the total.

Hi Eric:

I'm not sure how much of what I've done would apply to your situation.
Basically, the powers that be wanted some complex reports for an Access
application hooked up to SQL Server.  Access reports were not anywhere
near flexible enough to produce the output they wanted.  Consequently,
I ended up building a reporting interface onto the rather low-level python
pdf module and then hooked it up to the DB.  That way I was able to
do most of the complex stuff in python, use DTML templates whenever
possible, and output the results in pdf.  When the user clicks on a report
in access, the application shells out without them knowing it and the
next thing they know a pdf pops out in Acrobat.

I gave some thought making it available to whoever might find it useful
but haven't had much time to make it more friendly.  In particular, I
might take the pdf wrapper, which allows for high level pdf
formatting (for switching font sizes, styles, page numbering, headings,
etc), and somehow hook it up to zope.  Sometime after I started,  someone
did come up with a pdf document hook for zope, but it didn't offer the
formatting options I needed and my reports weren't going through zope.  It
might be worth a look, however, for your purposes.

If you can get away with it, avoid PDF documents altogether and just use
DTML to web enable your reports through zope.  I ended up using pdf
because the users didn't want to web enable this stuff, wanted more
precision then browser formatting allowed, and I thought it would be kind
of neat to try....

Subject: [Zope] Advanced DTML Question
Message-ID: <4.2.2.20000301155145.00b6c400@saladin.aisys.com>

I'm trying to write a DTMLMethod which will write out a list of data items 
found from a catalog, sorted in alphabetical order.  This is 
easy.  Basically I do something like this:

<dtml-in "Catalog(meta_type='foo')" sort=someAttribute>
     <dtml-with "Catalog.getobject(data_record_id_)">
         <dtml-var objvar1><dtml-var objvar2> ...
     </dtml-with>
</dtml-in>

I've got this working, no problem.  Now, since the list of these items 
might be somewhat long, I want to build a simple index at the top of the 
page and use page anchors to get to key points on the page. Basically I'm 
going to display the alphabet and when the user clicks on a letter, the 
page should scroll somewhere in the vicinity of an item which starts with 
that letter.  To that end, what I would like to do is have some code inside 
of my dtml-in loop which gets the first letter from the current entry, 
checks to see if an anchor for that letter has been written, if not, a new 
anchor tag is inserted into the stream.  My problem is I don't really know 
how to code this up.  It seems like maybe that at least some of this should 
be done at the Python level but I'm not quite sure how to split up the 
functionality.

Has anybody done anything similar who would be willing to give me some 
advice as to the best way to go about solving this problem?

Thanks.

Quick, possibly misleading idea:  if you can give your Catalog entries a
brain class with a function "anchorGroup" which returns the first letter of
the entry, then you can use <dtml-if sequence-first-anchorGroup><a
name="&dtml-anchorGroup;"></a></dtml-if>

That should have worked.  You should be able to manipulate your dictionary
just as you would expect.  What happened when you tried it? What do you get
from <dtml-var expr="_['dictionaryVariableName']">?

"Brain Class?"  Could you explain that a bit?  It so happens that the 
objects I'm getting out of my catalog are instances of a ZClass that I 
created.  That ZClass inherits from a basically empty Python base 
class.  Is this what you mean by a "brain class"?  If so, are you saying 
that I should just define a method in my Python code which does the 
"anchorGroup" thing?

Even if this isn't what you meant, I think I like the idea that you are 
proposing.  I just need to make sure that I actually understand what you 
are suggesting.

Thanks.

Thanks for the info on your PDF implementation.

Here's my situation:
I currently have a Java applet that collects data from my users.  The applet
runs some calculations and sends the results to me via email.  I copy &
paste the data into a Win32 VC++ app I wrote that converts the data into
"Forms Data Format" (FDF) using Adobe's SDK for generating FDF files.  I am
using Adobe's fdf DLL right now, but I'm excited about the idea of moving
this to Zope - No more Applet for my clients to download!!!

I have ZERO Python experience.

I use PDF / FDF because I am filling PDF files that are created by a
governmental agency; these are 'State Standard' forms, so I want to stick
with them instead of generating dynamic forms using Zope.

Question:  Are you using a Python code supplied by adobe for generating your
FDF file?  If so, I would be VERY interested in any Python code you'd be
willing to share that ties Zope to the Adobe code.

Thanks for your response.

PS, I'm replying to you and CC'ing zope@zope.org.  Is this an acceptable way
to keep the mailing list folks in the loop?
PSS, what's your name?

Eric.

No problem. 

BTW: I just discovered this neat function called string.replace(). =)

This is almost certainly faster:

    string.replace(data, '\r\n', '\n') 

I swear, not a day goes by that I don't learn something new about Python.

Subject: [Zope] How to check memory usage in Python
Message-ID: <20000301225439.43329.qmail@hotmail.com>

Hi,

This is more a Python question. How can one
check the RAM memory usage of a Python program
from within itself? Is there such a function?
(Is it platform independent? I mean, does
such a function exist for most platforms?)

If such a function does not exist in Python,
how can one do it from Unix (or Windows) shell
calls?

thanks,

Hung Jung

Message-ID: <Pine.BSF.4.21.0003011851120.5888-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * XML.com has published another Zope article by Amos Latteier,
    titled "Advanced XML Applications in Zope"

    http://www.xml.com/pub/2000/02/23/zope/index.html


New Products

  * Software Product: PMPSurvey, by "sleeper"

    This is another survey product.  It supports single and multiple
    answer questions.  It may easily be embedded within other web
    pages, and reportedly sports a nice management interface.

    http://www.zope.org/Members/sleeper/PMPSurvey


Updates

  * Software Product: FSSession, by "gaaros"

    This product can be used to maintain arbitrary per-visitor data
    (session data) without burdening your ZODB with excessive
    transactions.  It does this by storing the sessions on your
    filesystem.

    This update, 0.2.3, uses cPickle, which makes it faster and more
    flexible.  There are additional new features.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: BannerFolder, by "lalo"

    This product randomly displays one of it's contained ads or DTML
    Methods.  There are provisions for tracking click-thrus and for
    limiting the number of times an ad will display.

    The current version is 0.4.

    http://www.zope.org/Members/lalo/BannerFolder

  * Software Product: ZRadius, by "Zen"

    This is a Radius authenticator.  It can be used on it's own, or in
    Zope as a GenericUserFolder plug-in.  This is a bug-fix release,
    bringing the version to 1.1.

    http://www.zope.org/Members/Zen/ZRadius


Zope.org items

  * Zope Documentation Plan, by Amos Latteier

    Amos Latteier is soliciting feedback on his Zope Documentation
    Plan.  It describes the initiatives to improve the documentation
    situation which are underway at DC, their goals, and the
    assumptions they are based on.  If you would like to offer
    feedback, Amos is available at <amos@digicool.com>.

    http://www.zope.org/Members/Amos/Documentation/Plan

  * Tip: Using PythonMethods on FreeBSD, by "als"

    This tip points out that a module required by PythonMethods (new)
    is not enabled by default by FreeBSD's python port.  It describes
    the solution.

    http://www.zope.org/Members/als/tips/PythonMethod_FBSD

  * All Product Releases, by Martijn Pieters

    This page is designed to be used with wget, Go!Zilla, or some
    other web-sucking tool.  It contains links to every Product
    Release on the Zope site.

    http://www.zope.org/Members/mj/AllProds

  * How-To: Wizards Made Easy, by "jspisak"

    This document explains a few techniques which make it easy to
    create simple multiple-page forms, like Windows' Wizards.

JC,

It was intended as a self registration sandbox environment for a Birds of a
feather group at a conference.

It basically allows users to self-register and then creates an area for them
to experiment with Zope.

Most people seem to be interested in the self-registration bit tho. (which
is quite strange as this is only a few lines of a python external method,
whereas most of the code is taken up with mundane stuff).

Is it at all possible to have this list set reply to?

since problems discussed and solved here are logged for others to search,
surely it would be best if, by default, replies to these messages came to the
list?  I know it's just a little thing, but it still bugs me.

I know that on other lists to which I subscribe this is done.

Anyone else have an opinion on this?

be great to have a seperate archive of ZWN as a more concise form of

    You've no doubt noticed that over the last couple of months, the
actual list content in the ZWN has dwindled to nil, excpet for
zope-announce.  :-/  I'll change that first paragraph of the ZWN next
week.

That depends on what you want the 'dynamic' content to be, and where you
want to get it from.

Perhaps the webmaster at zope.org could add a how-to search interface to
the how-to listing page? You know, one that searches only how-tos (or
how-tos and tips). Sometimes using the current search box yields lots of
not-so-useful links. :(

Don't forget that you can click on the cplum headers on the How-TO index
page to sort by that header, and a second click will reverse sort.

For example, to sort by date, click "Date".

can we really run apache without running zserver?  i've been running apache as

then maybe i'm doing something wrong.

My email window dies suddenly, before I could write what I intedned ...
looks like it sent itself waaay too early. Sorry.

Anyway, have you tried the batch processing instructions at
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.5.html
They should give you some insight as to how to get the first letter. You
may then be able to set a temp variable, called CurrentAnchor, for
example, that contains the last letter that was used to set an anchor.
Testing agaimst the CurrentAnchor, you should be able to set (if not the
same), or continue (if the same).

Unfortunately, ZCatalog apparently doesn't do reg-ex searches yet.
Otherwise, I'd say create your links a alink to a page that looked for
thins that started with that letter.

Alternatively, you could look at the howto, and give a range of letter,
say a-e, f-j, etc. and just use the batch processing capabilities in
DTML. :)


Just some ideas.

This may be well hashed for most here but I'm curious about this. I've
noticed that most true mailing lists operate like this zope list, whereas
the lists I subscribe to via services like eGroups perform more like Curtis
would like it. I'm with Curtis on this, it seems much simpler to just send
the reply to the list... if I hit "reply to all" the person I'm responding
to and the others that have particpated in the thread get at least two
copies... one direct and one via the list. I'd have thought that the
multi-copy thing would quite bothersome for most overloaded list-partakers.
Plus the fact that at least some of the time messages must unintentionally
never make it to the list. I can sure live with it the way it is... but can
you give me an idea why "the standard makers" thought the way they did/do?

Thanks

I think so.  A "brain" in obscure Zope parlance is a class used to enhance a
raw tabular record, such as a ZSQLMethod or ZCatalog returns.

Hmm.  Somehow you aren't getting a dictionary, then.  It's hard to tell from
just what you've posted where it's going astray.  Are you dtml-return-ing a
literal dict as in your initial posting?  How is dictionaryVariableName set?

You need to hack the z2.py file.  Go down near the bottom (look for the
string '# HTTP Server') and you will see that the HTTP server is fired
up on the IP_ADDRESS interface.  This variable is defined on line 252
and the default is an empty string '' which means, 'all interfaces'.

You can hack the code here to do anything you want, define a bunch of
interface variables, etc...

Yes, this needs to be done better, but short of comming up with a conf
file like apache and dealing with all that, it's probably no so
realistic.  z2.py is currently config'ed with command line options,
which gets out of control after a while.

Erm... since when is the reply to field of an e-mail header NOT standard?
Why is it a bad idea?  It means the default action of replying to a message on
this list is to contribute to the list.

I'm not saying you are wrong.  I just would prefer a clear explanation instead
of an outright "that is wrong."

Well, one aspect of it is summed up in two words:

	Mail Loops.

Mail loops involving mailing lists get real nastym real fast. While it
is true that most MTAs have capabilities to detect them, it is also true
few are very effective, and even fewer admins even try to enable them.

As far as the two copies aspect, I hit reply-to-all, and delete the
individual from the recipient list. Some mailers do it properly and have
group, and individual response options.
A third aspect is end-user filtering adn reporting. On lists where the
headers are munged, often the client reader doesn't display attributions
correct, or sort correctly.

I believe i mentioned that everything in my email was from my questionable
understanding of ZOPE.  However, since nobody else has said "erm.. no, that's
not correct" i'm led to believe my assumtptions were correct. (o8

Personally, I've only used ZOPE directly with ZServer, or via an Apache server
with proxying (i don't count my as yet abortive attemts with apache and fastCGI
:)

From a review of my original assumptions (and actually looking further) i may
have been totally incorrect, believing the Zope.cgi might be a program you
could simply drop into your CGI directory, and presto.

But from closer examination, and some testing, I don't belive this is true.

You still need ZServer, I think this person meant that ZServer wasn't
actually listening on any outside ports, just the local domain socket to
Apache.

FYI, Zope used to be able to run without ZServer, but it was single
threaded.  You can still do that now (I imagine) but if you want
concurency you need ZServer.

Subject: [Zope] how much resource?
Message-ID: <0003021244090L.00679@tokey.kedai.com.my>

hi all,
i'm happy to say that our site (www.emedia.com.my) has been running steadily
since feb.  and we got our first 1M hits per day yesterday, and zope didn't
screeched to a halt.

now i'm wondering how much resource <dtml-if> ..<dtml-call>, <dtml-in> affect
the sending out of data to users.  will a lot of if and ins bog down the
server?  i wanted to do two different page for the same contents i.e. pages
with tables, and without tables.  i intend to do as what zope.org does for
printable page where we set a variable in the url or maybe set a cookie.  to do
that, i need to have an if statement in all files looking for that particular
variable and render the apropriate header file.   will this affect response
time? i've looked at chameleon skin but could not grasp the way it works.

if anyone got better ideas, better solution, shoot it here.  thanks

Zopistas,

I notice that there are two "performance" options with Zope, proxying

The digest version is that adding a reply-to field clobbers legitimate 
reply-to headers, that many mail readers will have difficulty replying 
to the sender's address without resorting to cut and paste, and that
it renders the 'reply to all' function on most mailers useless. 

Further more, on 'reply-to' style lists it's quite common to see
replies to messages that were intended to be send to the sender end up 
on the list - to the annoyance of the list readers, and often the
embarrassment of the person replying.

This is the downside to CC style lists. One day it will piss me off
enough to write a patch for Mailman so that it won't send a message to 
a list member if they are already in the To: or CC: fields.

Better than the other way around. See above.

The Reply-To field is intended to be a way for you to indicate the
email address that you can be contacted with when the one your sending 
from doesn't necessarily receive email - ie, you're migrating between
accounts, or posting to a publicly accessible list from an account
that isn't receiving email from that list. Whatever. The point is that 
we want to keep people's reply-to fields where possible.

Yes.  Measureable in milliseconds.  It's really not that much to worry
about just doing one conditional evaluation.  What you really want to
avoid are long loops.

A reply-to field itself is not against standards, the requested _use_ 
of the reply-to field is. Slight difference ;)

[The applicable standard is RFC822.]
(of course, technically speaking, the modified subject line in this very
post is in violation of the standard, but since it doesn't tend to cause
nasty mail loops, it largely goes unnoticed :) )

Right. Now what happens when Joe User takes a trip, and sets his 'I am
on vacation.' autoresponder on? That response is sent to everyone. That
response generates another email to him ... continue ad nauseum. Or
consider the target email being no-longer-valid. You get a mailer-daemon
response telling everyone on the list about it; which includes the
target thus generating an error which....

Granted,  when all parts of the peices of the puzzle are coded properly,
that may be reduced in frequency and/or intensity, but unfortunately,
many, many manchines are not set up properly, and software isn't coded
correctly.

See my other response. On top of those, I would add the issues with mail
<-> news gateways and loops that can/do occur as a result of improper
header munging.

what Bill said about this issue having been turned over endlessly is true,

OK... here is something I was talking with my workmates about.  So, i send a
message to the list from somewhere other than my list registered account.  If i
was migrating accounts, or whatever, i would change my details with the list
server.  Mailing Lists should only be sending to registered addresses, surely?

so, the list server doesn't care where the message came from (or maybe it
does), and has a FIXED LIST (as far as it's concerned) of people to forward the
messages to.  Why does it care what is in the reply-to field?


on another point that is showing in this list... Reply-To-All buttons...

having reply-to set cirvumvents ALL the problems with duplicate messages, etc.
I have the option of a) Reply-To-All, and risk doubling to someone,
OR
hitting Reply, and getting the mailing list server to send it on to everyone
appropriate.

Be warned that this is a religious topic, and that the technical

the arguments from the other side.  The following URLs contains 
reasonable arguments on both sides:

Note that there are also some good pro-reply-to arguments under the

A small note: Given a message with a CC list list _and_ a Reply-To
set, a group reply on Many (even most?) MUAs will send the reply to
the Reply-To and ignore the CC list (IIRC the RFC is ambiguous in
this matter).  In this manner if an individual is using Reply-To
correctly (to hide the fact that they can't receive mail at their
From: address), they are also cutting the other recipients out of
the loop for replies.

Dangerous.

Conversely, if a list does do reply-to munging, this doesn't happen,
but the "proper" address for the original post is usually lost.

This is off-topic however.

Martijn, it is not problem of timezone setting. If yes I had to see the

29.2. date. I think that it is a bug in bobobase_modification_time. The
system time is OK, only problems with bobobase_modification_time.

A very meek greeting..


Ok... i have now seen the error of my ways.   I fully admit i was not aware
there were so many problems to what seemed like such a simple convenience.  I'm
sure i can live with trying to remember to set the To address.

Please,  _I_ require no further conviction in this matter.  The information has
been provided as i asked (thanks to all who did), and I have been made suitably
aware of why this (and many other) list avoids using the reply-to field, for
the simple matter of 'avoiding problems'.

Hey.. by the way... has anyone else noticed the prolific nature of vagueness in
RFCs?

Its the old game:

  Only what is stated is defined.  

  Some things are stated to be "implementation dependent".

  Everything else is undefined and might involve green hairy
  martians coming out of someone's nose.  Or not.  Or both.

RFCs are a little better (or worse, YMMV) than standards documents
(which aren't really written in english per se), as they often
concentrate more on "intent" than definition.

If you're running Debian/GNU Linux, you need the python-dev package,
but then why not install the zope packages?

Message-ID: <Pine.LNX.4.21.0003020306150.8576-100000@zaibach.twistedmatrix.com>

just to elaborate on a few common points that have been brought up on this
list, and covered here: 

> http://www.metasystema.org/reply-to-useful.mhtml

1) "It's against the standard":

Quoting directly from that article:

The first thing to consider is that RFC 822, the document which defines
the standards and usages for email, specifically mentions this usage in
section 4.4.3:

 A somewhat different use may be of some help to "text message
 teleconferencing" groups equipped with automatic distribution
 services:  include the address of that service in the "Reply-
 To" field of all messages submitted to the teleconference;
 then participants can "reply"  to conference submissions to
 guarantee the correct distribution of any submission of their
 own.

It's not "against" the standard.  It may be a quirk of the
standard.  Detractors, please familiarize yourselves before FUDding.

2) "It causes mail loops."

Can someone please direct me to a record of this actually happening?  
It's certainly not common, and I run all of my lists with munging on.  It
doesn't cause problems there.  Several other lists (yes, some of them are
even "real" lists) that I subscribe to use munging and have never seen a
mailloop.

3) "Autoresponders are upset by it."

If you're going to use an autoresponder, configure it responsably!  Better
yet, don't use one at all.  They are annoying.  Mail loops generated here
would happen anyway.

4) "It removes useful information."

If you're using the 'reply-to' header rather than your 'from' header to
encode the address you want responses sent to, I know this is within the
standard, but you're wasting my bandwidth and my time.  I don't need to
know both what machine you sent from and what machine you want me to reply
to.  Just put your own address in the 'from' header.  (This is what most
people do anyway.  I don't know anyone that works otherwise.)

5) "It removes freedom"

This is a crock.  Anyone with a reasonably written mailer can respond to
messages how they please: reply-to munging makes it easier to reply *only
to the list* which is almost always the required functionality.  If you
really can't live without the original reply-to header, maybe you should
consider posting a message to the list asking the person's private email
that you want to get in touch with: you should really be requesting to
take on-topic discussions off the list in the first place anyway.

Speaking of wasting my money / time, if you're going to be a detractor of
reply-to munging, PLEASE be thoughtful enough, at least, to remove the
inevitable list of 18 or 20 recipients that cruft up to threads over time.  
This 'conscientious' behavior, as described by Chip Rosenthal, has gotten
me CC:ed on some messages 2 or 3 times on unmunged mailinglists.  I find
this annoying, but less so than getting flamed for sending out 8 replies
to a single mailing-list message.  And I like to conserve bandwidth.

This is much-repeated stuff, but I hate to think that there's this image
that technically sophistocated people all hate munging and think it's
evil.  Chip's opinion is, as the author of the essay referenced above has
told me, treated as gospel, and there are definitely two views on this
topic.  I strongly adhere to one, obviously. :-)

(Please, no flames, no personal email about this.  I'm not going to be
convinced of anything, this is just a message to make sure that 'newbies'
to list administration don't think that there is one answer to this
question.  It's not really for those of you who seriously consider munging
bad, and I certainly don't hope to get the policy on this list changed by
it; that would only spark more discussion of this, and one extra email
once in a while isn't so bad compared to thousands upon thousands of
messages in this thread... ^_^)

Hi,

Can you please tell us what is the configuration of your machine.  I am
very interested.  We had our servers crawl to halt when we used Zope but
we had other things running at the same time.  So I will appretiate it if
you can give us the configuration.  Are you using a database? Is it on the
same machine or by itself, and if so what are the configuration of the
supporitng servers.

1M pages/day is a great number, I think that if a farm configuration is
used you can create an extremely dynamic and scalable site.

TIA
Adonis

I've walked through the beginning tutorials on managing zope.

I was hoping there would be something similar to show a newbie
such as myself how to use Zope's ODB to define some objects and
create dynamic content pages based on them.


[RH] Um, without plugging my own document, you may want to check out my
'Changing Contexts in Zope'; reading your post it may be what you want. It
is not (meant as) a howto, but a bit more general. It should go into in the
ZBook of ZDP (watch this list for announcements about ZDP rsn). In the
meantime it is available from my member page:

In addition to the valid uses posted otherwise ...

Real life example:
 At work, I am within a corporate firewall. On my unixen, my email
address is local to the machine, ie. bill@somehostname.bigcorp.com. If
you reply to that, you will be wasting your time and badwidth, since you
_can't_ access it from outside the firewall. Thus, I (in this example)
add a reply-to that has a _useable_ email address, ie. one avaiable to
you, form outside the firewall. I personally know of several hundred
people who do this, and several thousand who _should_ be. And before you
say it, no, not every mailer lets you set the 'from' header.


The point? Now you know someone who uses it. ;^)

How can this be on topic, you ask? Read on. :)

I've notice a certain increase in the amount of 'sending mass email with
zope' messages lately, and not many solutions.

Since I don't zope on windows, one method I have used when wanting to
avoid the sendmail tag (I _was_ having problems with the friggin thing
not working), was to shell out and call mail (or mailx, depending on
your *nix) to send each message. Problem was, when doing that, the
'from' address was 'nobody@foo.bar.com'. Since I wanted replies, I had
to add the reply-to to get a response that was useful.

(Hey, I din't say it was a strong effort to bring it back on topic for
the list :)
Perhaps those wanting to send out mass emails *cough*spam*cough* with
zope, and not finding answers from within Zope and the sendlmail tag
(yeah, I still look at that puppy with suspicion and a sneer :) may see
this as an option

hi, we have a PIII 500 M, dual processor running rh6.1 with 712M RAM.  there's
only zope there, and mysql to cater for banner ads.  i'm using phpAds for now
until we got a commercial ad server or until there exist a mature banner ad
products for zope. (i'mm eyeing banner ad with interest tho..)  everything is
in one server, although we're looking at adding another server for redundency. 
don't know yet how to go about this.  anybody got any pointers?  maybe
failoverd? (http://ps-ax.com/failoverd/ ) or eddie?(www.eddieware.org)

the 1M number is hits, not pages.  we have max 600k pages/day last  feb.  this
is our second month so, hopefully zope lives up to its standard.. or i'll need
to find another job *grin*

I only noticed it today (2000/03/02): the undo logs show
2000/03/01, and so do ZWiki times. This appears to be a bug in
bobobase_modification_time.

<dtml-var "_.DateTime()"> does show the right time, and the 'Content
changed' notification Zope gives does too. The bug happens on both
Windows NT and Linux.

Thankyou.
However,to help my understanding how does this work?

Hope you don't mind - I've mailed my other, unanswered

Message-ID: <38BE5FB6.9EFCCE4C@open.ac.uk>

In the depths of a tree tag I want to pick up a
property of the "current" object without acquisition
if the property isn't present.

This code seems to work when used not in a tree tag
but when its in a tree tag it still finds the property
from higher up in the acquisition space.

What gives? How can I do this?

The version below doesn't fall over if the property
isn't present on that object, it just finds it by acq.

To fully round out this little performance study (small study of 
course) could you tell us what capacity the machine is at as far as 
you know, what Zope version you are running and with what 
configuration (Zserver alone, w/ Apache etc)?

These kinds of things are really helpful in determining Zope's 
ability to scale and in winning out the hearts of iCEO's.

Thanks,

Martijn, it is not problem of timezone setting. If yes I had to see the
difference in past also. And it was OK. The problem started with
29.2. date. I think that it is a bug in bobobase_modification_time. The
system time is OK, only problems with bobobase_modification_time.

The best test is creating a DTML _Document_ (not a Method!), with the
contents:

  Modified: <dtml-var bobobase_modification_time><BR>
  Current time: <dtml-var ZopeTime><BR>

Subject: [Zope] Problems installing Zope
Message-ID: <38BE54C2.B71E007E@rdel.co.uk>

Having just successfully installed and setup Zope and Squishdot
on an 486 Linux box (Debian packages made it dead easy), I
thought I'd move over to a SUN box as it is quicker and I want to
run a discussion group for the intranet here.

[SunOS 5.5.1 Generic sun4m sparc SUNW,SPARCstation-10]

After installing the latest python (and then re-compiling with
threads, doh) I unpacked Zope-2.1.4-src and ran wo_pcgi.py.
Everything seemed to go fine, so I simply fired it up using
./start. After a couple of seconds Zope (okay, Python) falls over
reporting that the ExtensionClass module couldn't be found at the
import in ZODB/__init__.py.

Actually, after investigation, none of the modules would load
from an import even though they all have .so files present in the
lib/python dir. Now, I don't know a thing about Python so I don't
know where to look to sort this out... Any ideas?

Is it something to do with shared libraries being handled wrongly
on SunOS 5?

Only other thing I can think of is search paths. I install
outside of /usr, but I can't imagine that would be a problem. Do
I need to set a PYTHONPATH or something?

Help...

I've put this into the collector, the bug is a bit weird for those, who
use bobobase_modification_time quite heavy, like me :)

aah .. the 'content changed' is a bit irritating, but it's only the
notice 'content changed' and a <dtml-var DateTime> in the next line.

Okay, my code was unclear in the example (though with a new created
method the modification time of the container should have changed too:),
but I'm quite sure, it's a bug.

Or, as someone else pointed out, you could use the -a parameter to z2.py.

Just run z2.py --usage for all command line options.

Uuuhhhmmm.. <g>

I just tested this myself. Here's my output:

   Modified: 2000/03/01 13:06:16.05 GMT+1
   Current time: 2000/03/02 13:06:17.86 GMT+1

Heh. One day off. And so is the Undo log.

My apologies for my unduly applied sceptisism. I'll go and hide now, and
investigate.

   I have Zope installed and running on Sun Sparc Solaris 2.5.1. Zope is in
/usr/local/Zope. There are 17 .so libraries in lib/python. Zope is running
fine: http://sun.med.ru/~zphd/
   The only thing - I am running under Apache with PCGI, no ZServer.
Nothing special for dynamic linking...

Or use CVS load_site which has a -I feature that for every index.html

Apologies for the late reply - flu :(

Yes. I create a DBH in an EM and fire away. All I get from the Zope 
system is a request of the form http://supercascade?root_id=240551 
and I start to do my queries. They are nested in the EM to 9 levels 
deep (but normally the first 4 levels are enough to get all the nodes 
of the tree with the relevant root_id). Getting the list of nodes is 
quite fast, about 0.8 seconds. Then I have to render them. I've got 
that down by a factor of ten (since this thread has started in actual 
fact!)

I've also found out just how fast a cached ZSQL method can be - one 
DMTL method that used query took 3.2 seconds on the first render, and 
0.06 seconds on subsequent renders. Obviously some more work needs to 
be done in this area and I'm looking into that.

I'm also told that our MySQL server itself does some caching ... 
looking into that.

Ah, I hadn't thought of that...my query isn't recursive however.

MySQL (MySQLmodule-1.4), DocumentTemplate and from 
Acquisition,Implicit in the main.

thanks for the thoughts Martijn,

Dunno if this is related or not, but I got some really weird errors yesterday
when trying to view some images I had created in Zope on the 29th.

All I was trying to do was view them using the image's view tab and I got a Zope
error. Something about an invalid datetime stamp I think but try simulating it
yourself if you want the exact answer...
They also appeared as broken images when I included them on pages using
<dtml-var image>

so, Zope doesn't like leap years? ;-)

A little while back I uploaded a patch to the ODBC Database Adaptor

Indeed it did, but unfortunately it broke a host of other things.

Anyone who downloaded the patch the first time around may be

I have a page that has the same SQL Method called a few times....

Do some more stuff

<dtml-in sqlMethod query=start_query>
Do some more stuff

Does anyone know the inner working well enough to tell me whether or 
not Zope actually makes two separate calls to the database or whether 
it makes one caches it and uses the results twice?

If you know and would like to expand on how Zope deals with caching 
SQL data that would be great I am trying to optimize my Zope 
installation and don't want to tax the database.

Hi,

Can anyone tell me what are the predefined error types
for the <dtml-raise type=...> tag, and how to use them?
The DTML manual talks about "Unauthorized", and
"Redirect", but doesn't give any details. I haven't found
how to use "Redirect" so far.

Thanks,

Stefan.

Dunno about raise, but if you want to do a redirect, try (untested,YMMV,etc)

<dtml-call "RESPONSE.redirect(url)">

Function TimeStamp_yad(int y) in
zope-2.1.4-src\lib\python\zodb\TimeStamp.c
expects a 1900 based year (i.e. 0 = 1900, 2000=100, etc.), 
for positive agruments, when computing (y+300)/400.

TimeStamp_abst(int y, int mo, int d, int m, int s)
seems to expect a 0 based year, on the other hand.

l = y%4==0 && (y%100 != 0 || y%400==0)

But it gets called with a 1900 based year in line 290 in 
function TimeStamp_timeTime(

Phil,
    nope.  Doesn't find the property called rubbish.

Baffled.
Perhaps its an architecure-related bug -

Here's what I've got.  First, I have a DTMLMethod named creditCardsAccepted 
which is defined as follows:

<dtml-return "
{
'Visa':'V',
'Mastercard':'MC',
'American Express':'AE',
'Diners Club':'DC',
'Discover':'DS',
'Carte Blanche:'CB',
'Japanese Credit Bureau':'JCB',
'Transmedia':'T'
}">

I then have a method called creditCardSelections which is defined as follows:

<dtml-return "creditCardsAccepted.keys()">

(I also tried <dtml-return "_['creditCardsAccepted'].keys()">)

When I try to "view" my creditCardSelections, I get the attribute error on 
'keys'.

Just tried that, same results (keys error).

(BTW, there was a typo in my message describing the dictionary I was 
returning.  The typo existed only in the e-mail, not in the actual code)

Subject: [Zope] Subclassing User
Message-ID: <200003021337.OAA05522@OSKAR.ingo.net>

Hi!

Can anybody tell me anything about subclassing a UserObject?
I have had some neat errors (including seg-faults and indefinite loops by just subclassing a ZClass from User Object)
When I tried to insantiate a Subclass of UserObject Zope quit.
(I did not change anything to the default constructors and expected something like "missing argument", but not an indefinite loop :)

I am using Zope 2.1.4 on Linux/x86 (2.2.13)

Thanks.

Regards, Ingo.

Followup,

I just realized that I had two definitions of "creditCardsAccepted".  One 
was defined inside my ZClass, and one was defined in the folder containing 
the ZClass.  The one in the container was just answering a list.  When I 
changed that one to answer a dictionary things worked.  I then simply 
deleted the DTMLMethod in the containing folder and now I get a name 
error.  Now I'm really confused.  After deleting the higher level method, I 
now have the creditCardsAccepted and the creditCardSelections both in the 
same folder.  It seems, however, that the creditCardSelections cannot see 
the sibling method.

I'm clearly overlooking something.

Andy,

Do all of the objects have a property 'rubbish'?

Try something like:

<dtml-with aq_explicit only>
  <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
</dtml-with>

This should check that the rubbish property exists and change what gets
rendered depending on that.

J,

In the advanced tab on the edit page of a SQL Method there is a entry box
for caching information.

You could start by looking there.

Phil,

> Do all of the objects have a property 'rubbish'?

No, only some of them.  The problem goes away if
I make sure that every object has some value for
this property but that's not a good solution.  The
code you suggest (the dtml-if ...) is exactly what I intended
but on my system (Linux slackware 7 + zope  2.1.4) it finds
higher level rubbish properties.  Actually its not really
called rubbish, that's just what I was using to check
it worked before using it.

It simply doesn't work - if it works for you lets find
out what's different.  Are you on a windows platform?
What Zope version?

Just to restate the problem for new readers:-

The problem is to use "dtml-with X only" inside a tree rendering
so as to be able to test whether the current object
has some specific property.  The code works outside trees but
used in a tree it still seems to find properties by
acquisition.

> 
> <dtml-with aq_explicit only>
>   <dtml-if rubbish><dtml-var rubbish><dtml-else>No Rubbish</dtml-if>
> </dtml-with>


This code finds "rubbish" at higher acquisition levels.  I know it
shouldn't but it does.  Anyone throw any light on it?

Andy,

Hmm, I'm confused.

I use this 'trick' all the time, here's a bit of code from a method of mine:

<dtml-with aq_explicit only>
    <dtml-if url>
      <a href="<dtml-var url>" title="<dtml-if status><dtml-var
status></dtml-if>" target=main><dtml-var ident></a>
    <dtml-else>
      <dtml-var ident>
    </dtml-if>
</dtml-with>

Which works beautifully.

Hmmm

confusion reigns!??!

Phil

Subject: [Zope] urgent! help! strange blockings
Message-ID: <38BE960E.32E0F12E@wildenhain.de>

Hello,

I cannot get ride of those strange blockings of zope.
This happens from time to time and leads some times to
minutes without action from Zope.
I increased threads pool and decreased it, I use a much
bigger object cache (memory is not an issue on the machine)
and I pured the database (with help of an extra machine)
Zope stucks with about 18% processor use and does almost
nothing at the moment.

Any posibility for an dead-lock?

Help is very appreciated!

Configuration: Zope 2.1.4, ZODBC, Database-Size: 66MB (after purify)
Some sessions with unsafed work, 50 threads for pool, NT 4.0 (ok, this
sux, 
but we have to use ODBC with strange Databases)

I posted a message about this this morning. In effect, yes you can 
use caching and it is veery fast (one second and subsequent renders). 
For your document, I think you'll find it will speed up by a factor 
of how many times the ZSQL method is called...

ps it's the 'Advanced' tag. Put something in the 'cache results for n 
seconds' box

I've tried to do something like you suggested, but it doesn't seem to 
work.  I'm probably not doing things quite correctly.  I've added a 
"getAnchorCharacter" method to my ZClass which correctly answers the 
character I want to use as an anchor.  I've tested this and know that it 
works.  I tried using "<dtml-if sequence-first-getAnchorCharacter> ...", 
but got no result.  Could you explain a bit more about how something like 
"sequence-first-xxx" works?  I haven't found any information on this form 
of a dtml-in variable.  Perhaps I'm just misunderstanding your solution.

In thinking about this solution, it seems that if I'm inside of a dtml-in 
iterating over entries in a Catalog, the objects known to the "dtml-in" 
aren't instances of my ZClass, but instances of some catalogging wrapper 
for my ZClass.  Therefore, it would seem that my getAnchorCharacter method 
wouldn't be accessible from within the dtml-in, but only from within a 
dtml-with which sets the object to be the object referenced by the catalog 
entry.

Can you clarify all this?

Thanks.

No light, no solution, only a bad workaround:

<dtml-let temp_rubbish=rubbish>
  <dtml-tree ...> # your tree code
  ...
    <dtml-if "rubbish <> temp_rubbish">
      <dtml-var rubbish>
    </dtml-if>
 ...
 </dtml-tree>
</dtml-let>

Check the Grouping Variables subsection of
http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.8.html

I did give you the wrong syntax; it's <dtml-if first-getAnchorCharacter>,
with no "sequence-".

I misunderstood you.  The catalog wrapper is the "brain" which needs to have
the getAnchorCharacter method.  But... Suppose you add getAnchorCharacter as
a catalogued meta_type in your Catalog?  I think that would work.

Subject: [Zope] ZOPE!  I HATE YOU!
Message-ID: <20000302105256.A23108@devware.com>

It used to be that I was so open minded when it came to web
technologies.  I used to say "Oh yeah, pick whatever you want, we can
do it in that."  I used to say "No problem!  We can use your scripting
technology!  It's just as good as any other."  And I would, and they
would, and we did.  And we'd all stand around and say "Yeah
man... that's cool."

And then Zope entered my life.  And NOW I simply can't think of
virtually any project that Zope wouldn't do a better job of serving
than those *other* technologies.  It's very frustrating when every
time you see a project you think "Oh, Zope would make that SO much
easier!"  Especially any time someone mentions the word "Database" and
"Web" in close proximity.  The truly frustrating part is staying
focused on the problem-space when you have such a fun technology to
play with.

Now in some ways I'll admit, this is an exaggeration.  Obviously,
there ARE lots of cases when Zope isn't appropriate, but I just wanted
to shout out a big thanks for developing such an awesome system that
makes developing apps so easy to do.  Now if I could just get my mind
off of it's possibilities long enough to evaluate those OTHER
technologies objectively, then I'd be in good shape. ;D

Message-ID: <200003021716.MAA27689@amarok.cnri.reston.va.us>

I've made a new release of Oedipus, a Python package for presenting
data from the Open Directory Project.  
 
http://www.mems-exchange.org/software/python/oedipus/   

In v0.06, The improvements to the ODP code itself are pretty minor.
The major milestone is that, after some diligent sleuthing,
Jean-Claude Wippler tracked down an obscure bug in MetaKit that I was
tripping over.  A patch for MetaKit 2.0 is included in Oedipus 0.06,
so for the first time you can actually handle a complete ODP dump.
You'd better have 400Mb of disk space for the resulting data file,
though, plus 500Mb for the source XML files, plus 4-5 hours of
processing time (at least on a 550MHz Linux box).

The exported ZClass product still doesn't seem to work, though; if you
untar it in a new Zope installation, no Product is added when you
start up Zope.  Anyone else notice this problem?

Me too, I think. I haven't investigated this more deeply yet
but I noticed that all new News items created since March 1 in
the PTK portal I've been playing with get their
dates set back to 29 Feb the moment they are modified
(by being approved, for example).

and tried ./start again but the script seems to lock up after displaying the

apologies, ignore my pervious posting, try instead:

Subject: [Zope] [Newbie]  SQL database support on NT
Message-ID: <NDBBLMHEELDKLGHEEMJPIEMMCBAA.bac@ivc.com>

Hello All:

I'm just beginning to play with zope and really like what I see.  No Zen yet
but it's coming.

The project I'm working on must use NT as the server, much to my
displeasure.  I need to select a SQL database for the project and need to
find one that will work and play well with zope.  Searching through the
Guides and How-to's has left me a big puzzled.

Looking at the "Database Adapter Roadmap", it looks like there isn't a
direct adapter for SQLServer.  is this correct?  Will the Oracle adapter
work on NT?

If not, is my only choice to use the ODBC adapter?  Or the ZJetAdapter for
MS-Access (which I don't think would be sufficient for my needs)?

Any suggestions for database selection on NT will be appreciated.

Thanks,

Brad

It looks like you are indeed running the query multiple times. Unless you
are changing the data at some point internal to the process, which would
require your to "refresh" the results in order to have current data, you
could try:

<dtml-in sqlMethod query=start_query>
Do some stuff
Do some more stuff
Do even more stuff
</dtml-in>

Youd be "recycling" the result set, and sparing the DB backend.

I'll give that a try.  If I wanted to add a method to the catalog wrapper, 
is there a non-invasive way to do this or would I have to modify some 
standard Zope code to work differently?

We have been running an in house (approxiamately 100 users) contact management and order process site on NT 4.0 for several months
now using Visual FoxPro as the back end database (on a different NT machine) via ODBC and have had few problems. The zope machine is
a dell P3-400 w/256megs of ram. The db machine is a generic P2-200 with 512megs of ram. They are connected through a 100mbits
intelligent switch. However both machines now have dual port 100 mbits cards and we are in the processs of using the extra port on
each card to direct connect the 2 machine.

Our application is db intensive (every sql method involves at least 1 wrapper call to determine the AUTHENTICATED_USER's access
level) Unless there is network congestion and can display an order form (2 frames each the result of 5 to 10 sql methods) in about 2
to 3 seconds. (Response is 3 to 6 times faster via browser and ZOPE than throught the VFP apps that were originallly written to 2
this. )

VFP makes a very fast backend because if you are using only indexed columns and/or expressions the it can determine the record or
records entirely from the indexes meaning it never pulls data out of  the data file till it knows exactly which records to get.
Single record lookups - even with complex queries - are almost instantaneous.

LoginManager now has this capability. The loginForm is passed
"needroles", the list of roles one would have to have one of to perform
the action that prompted the login. Thus you could do:

 <dtml-if "'Member' in needroles">
  ... member login form ...
 <dtml-else>
  ... manager login form ...
 </dtml-if>

(note that 'Manager' is likely allowed to do both member and manager
things, and thus checking "'Manager' in needroles" would be true in
either case and not do what you want)

Hey guys. 

I'm currently in a minor bidding war with the Oracle group here over
whether we re-implement some intranet programs in Zope or in Oracle
WebDB. I've got them on just about everything, except calling stored
procedures. 
Now, I know that ZOracleDA supports Stored Procedures. So I'm guessing
that something like the following would work, but I'll be buggered if I
can figure out how. 

ZOracleDA Connection : oracle_da
External Method : find_target(search_string)
Oracle Package : Program1
Oracle Procedure : Proc1

def find_target(self, search_string):
  c=self.oracle_da.cursor()
  s=self.oracle_da.procedures.Program1.Proc1(search_string,c)
  return c.fetchall()

Am I missing something? I can't even get -- 
>>> import DCOracle
>>> dbh=DCOracle.Connect('user/pass@DB1')
>>> c=dbh.cursor()
>>> sth=dbh.procedures.pgm1_api.find_target('spam',c)

Subject: [Zope] SQLSession and Performance issues
Message-ID: <38BEDC9C.734F4754@exceptionalminds.com>

Hi all,

I have a form on which I am having some interesting performance issues,
I think, but am not sure that it is my extensive use of SQLSession
variables throughout the form.

I have a single page data entry form where almost every field  gets
stored in the SESSION. This form can take from 9 to 15 seconds to
display. When all my other forms take 1 to 3 seconds this is a
significant slowdown.

I am curious as to what methods may be used to reduce calls to
SESSION['varname'], or if I am even barking up the right tree.

Thanks.

In the 'utilities' directory of Zope there is a tool called

ok.  by "a ZODB" do you mean that the call in my external method
is trying to reopen the ZODB zope is using?  i'd assumed i was 
crating another one, with a separate FileStorage.

ok, then how does code in my external method get at that?
that is, how do i create an object and stuff it in the DB?
all the code examples i've seen follow the pattern in GetPeople().

> AFAIK, you simply need to create an instance of your object and set it as

how do i do this?

i get the feeling i'm just missing something, perhaps thinking like
a python programmer rather than a zope guru.  i feel like there's 
some big obvious point that has escaped me, and i'm waiting for the
big "AHA!".

so, one more try.  given the following external method:

import ZODB, ZODB.FileStorage


def GetPeople( self ):
	"Return list of people in DB"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( 'TestDB.fs' ) )
	connection = db.open()
	root = connection.root()
	people = []
	for key in root.keys():
		people.append( root[ key ] )
	return people

if __name__ == '__main__':
	for person in GetPeople( None ):
		print person.name, 'is', person.age, 'years old'


referenced from a DTML Method:

<dtml-in "GetPeople()">
	<dtml-var name> is <dtml-var age> years old.<br>
</dtml-in>

when i restart zope and view the method, it works once, but shows
no persons.  the second time, it fails with the traceback.

what do i change to make it work?

thank you for your patience.

I have not followed the thread but reading this particular posting, seems
to me that you cannot do what you want to do (at least in a
straightforward way). Importing ZODB declares all kind of global
variables/methods, an important one being get_transaction() which returns
the current transaction. So if you do a get-transaction() in your external
method which transaction should it return? And how would the two
transaction managers interact? Couldn't you just register your root object
with the current ZODB (the one Zope is running), by just setting it as an
attribute to the root object?

Again I have not followed the thread so I may be way off topic.

Thanks for investigating this - because TimeStamp objects are 
used in the object database, I don't want to make any changes 
to this yet until I can talk to Jim and verify that the fix 
won't have any impact on ZODB code (mon. morning probably).

Last I checked, setting an SESSIOn variable immediately did an update
on the RDBM which would explain the slowdown. I do not know what the
current situation is but I remember Anthony mentioning he was thinking of
changing it. You might trying playing with the source code and store all
changes to SESSION in a volatile attribute and call the SQL method at the
end of the transaction only (at least this is how I do it in FSSession).

Your only choice is the ODBC adapter if you want tyo use SQL-server.
We're running Zope on a NT server with SQL-server as database.
It works very well.

Thanks... but I think I really need to raise an error:
I want to invoke the redirect in the standard_html_header,
so if I use <dtml-call "RESPONSE.redirect(url)">, only
the header will be redirected (I think...).

Another, slightly related question: On my zope, whenever 
there is an error, the whole Traceback is printed on
the error page, and this doesn't seem to be part of the
standard_error_message. Does anyone know how to hide it,
or to put it in a html comment, like www.zope.org does?

Thanks,

Stefan.

If a FieldIndex is treated as atomic, it shouldn't go trough
the Splitter, right?

I found out that an hyphen in a field indexed as FieldIndex
breaks the index (this field is just not indexed, it seems). A
space works. Weird.

I was working with my ZClasses today and was confronted with something 
which seems strange.  I was editing a method defined in my ZClass when I 
tried to click on the "propertysheets" link displayed at the top of the 
edit screen:

DTMLMethod at  / ControlPanel / Products / <product> / <zclass> / 
propertysheets / methods / <method name>

When I clicked on the link, a basic authorization dialog was displayed.  I 
was already logged in as the superuser.  Why am I getting an authorization 
dialog?

Mostly just curious.

Thanks.

I guess it depends on what database you are using. If your
database is a remote server hooked up through TCP/IP port,
too many calls to SESSION could be bad. Also, if the session
data is large, during the transimission many packets have to
be send.

I don't have an answer... maybe you could describe first
what database you are using (Gadfly on the same machine?
remote database?), do you do many retrievals and updates?

------------------------

In the code SQLSession.py, there is a 'caching' variable.
SQLSession seems to cache variables that are already
retrieved or are recently updated. Try to set 'caching'
to 1 and see if that helps.

------------------------

As Pavlos Christoforou said, another strategy is to
have a single session data variable (a dictionary,
for instance), and then retrieve it, say, in your
standard_html_header and store it in your standard_html_footer
(or their equivalents.) This way you only need to access
the database twice per request.

------------------------

Please post back... I am also very interested. You
can also time performance by calling time.time()
in Python or <dtml-var ZopeTime> in DTML. I am
curious in the source of the problem... It would be
nice to find out whether the time is spent in each
database query or in TCP/IP packet splitting/joining/waiting.

regards,

Hung Jung

PostgreSQL running on the same box as ZServer.

Thanks for this input. I will go and take a look at it. I did not know
it was there.

Now this in an interesting idea, but all my attempts to computationally
build a dictionary within Zope have gone to naught. I would love any
advice on this as I believe it could very well be the key to this
problem.

This will redirect the whole page, as it gives a client-side redirect.

it only does this if you're logged in, otherwise it puts it in a comment
(or displays your standard_error_message)

This ist a typical Y2K bug, located in the module TimpeStamp.c, 
as I suspected earlier.
 
Since nobody followed my hint from earlier this day so far, I took 
the opportunity to dig a little deeper, learning how to build and

Given how little documentation there is, I don't claim having 
understood anything about, but noticing that the function

static double TimeStamp_abst(int y, int mo, int d, int m, int s)

gets called with y=100 (not 2000), 

changing the leap yar calculation

 l = y%4==0 && (y%100 != 0 || y%400==0);

to

 l = y%4==0 && (y%100 != 0 || (y+1900)%400==0);

in that function fixed the problem on my system.

erm.. one question... are you running Squid?  Or anything else on port 8080?

try "telnet 192.168.1.100 8080" and see what it says.


p.s.  if you want ZOPE to start on bootup, i put this in my /etc/rc.d/rc.local
file (I'm running RH6.2.. your rc.local may be elsewhere, or a different name):

/usr/local/Zope-2.1.3-src/start &

I actually run ZOPE as user 'zope', so i use:

su -l zope --command=/usr/local/Zope-2.1.3-src/start &

This is the detail I did not notice, previously. I thought you were trying
to store objects in your Zope ZODB; I didn't notice that the filename you
were passing to FileStorage was not Data.fs.

Sorry.

I don't understand why the problem is manifesting as it is, but I got your
code to work by modifying your code as follows:

- for key in root.keys():
-         people.append(root[key])
+ connection.close()
- return people

Opening a connection without closing it is a Bad Idea. I just can't figure
out what this has to do with the lock file on the database. I figured when
I closed the connection it was deleting the lock, but this is not so. So,
I remain confused. ;-)

Hope this helps!

That's why I didn't suggest a fix in my first analysis. I don't know 
anything about the internals of the Zope object data base (hey, I 
learned about Zope only about two months ago, so what do you 
expect?). So I don't even know whether it's just a problem of 
displaying the wrong date, or whether wrong time stamps are 
written to the data base. In the latter case, most people would 
prefer to have that bug fix yesterday. Inconsistent dates in a data 
base are a serious problem, and it's getting worse as longer it lasts.

okey dokey.  the setup is not that big.  we're just starting out and are just
feeling our way here.  what we have:

a PIII 500 M compaq 5500 ,smartscsi with RH 6.1, zope 2.1.3. i tried running
zserver with fast cgi but it choked with high load.  so, in the end, it's
apache with pcgi.  so far, it handles all the traffic beautifully.

what we want, however - reliability, availability of our site, so that's where
we need to look now.  caching is also another matter.  currently we enabled
apache expire module, but  not quite sure whether that would have any effect on
pages served by zope.

yes, and are you going to use sql in the future?  or just stay with zodb?  i
would think going with sql is better in the sense that most of us have that 2G
fs limit, and putting data in sql would help separate data from zodb.

Hmm. ZClass products aren't automagically imported; when exported, turn into
zexp files, either on the client machine somewhere or in the server's
$ZOPE_HOME/var directory.  To install them on another server, on must:

  * copy the *.zexp file into the new server's $ZOPE_HOME/import directory

  * import the *.zexp file into the "Control Panel | Products" folder.

You don't have to restart the new server, either, unlike "normal" Python
products.

Unless somebody borrowed Guido's time machine and retrofitted Butch Landigan's
ZPack proposal, that is?

Tres.

Greetings.

To start imapd should be set to run vie inetd. In the /usr/doc/packages/pop
directory look at the BUILD file. This has the information for setting up
inetd.conf to work with the imapd. In short you need to edit a few lines of the
inetd that comes with SuSE. Mostly you will need to uncomment the imap lines
they should look like this:

imap2   stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/imapd
pop3    stream  tcp     nowait  root    /usr/sbin/tcpd  /usr/sbin/ipop3d

This will allow you to use the imap server or the pop server if you want to.

You may also want to check your configuration with a regular IMAP compatible
mail client like Netscape Messinger. FWIW I'm running WorldPilot on my test
server that is SuSE 6.2 (upgraded from 6.0) and works well.

Good Luck!
Jack

I checked my /etc/services file and it isn't showing anything connected to
port 8080.  Is there somewhere else I need to check?

//
// try "telnet 192.168.1.100 8080" and see what it says.
It says: "telnet: Unable to connect to remote host: Connection refused"

Then I added the "/usr/local/Zope-2.1.3-src/start &" line to my
/etc/rc.d/rc.local file, rebooted, did a "ps -ax" to see what processes were
running, saw that "z2.py -D" (in there 2 times).

So, I tried to telnet in agian and this time it said "Connected to
192.168.1.100"

Next I tried to connect to "http://192.168.1.100:8080/manage" with my
browser...

IT WORKED!!!!

Thanks a million Curtis!  I guess I just needed to add the line to my

Hi,

What is the difference between <dtml-call "...."> and <dtml-call ...>.  For
instance, if I have this directory structure:

|
+-base
    +-subfolder

from base,

<dtml-call subfolder.manage_addFolder(...)> doesn't add any folders, while
<dtml-call "subfolder.manage_addFolder(...)"> behaves as expected. It took
about an hour of experimenting before getting this right. Could someone
explain what is the difference here?

Thanks.

I would like to understand the source of your problem, too.

However, I think there is a misunderstanding here. In TM.py,
_registered is a class data attribute, which is typically
a trick for "initializing" Python instance data attribute.
That is, unless you explicitly do something like

  TM._register = 1

the class variable would never change. That is, TM._register
is always None. Always always. So there should not be any
problem in thread interference.

If x is an instance of TM (or an instance that has TM as
an interface, in the case of multiple inheritance), if you
look at the dictionary of x, i.e: x.__dict__ , you will see
that initially x does not have an attribute _register in
its own dictionary. However, x._register is a valid reference,
because it borrows from the class attribute. The statement:

  print x._register

would print out 'None'. As soon as you assign a value to

  x._register = 1

you create an attribute in the dictionary of x. That is, a
new item is added into x.__dict__ , which is totatally
independent of TM._register. So TM._register remains as None.

I'd like to take a look into it, too. But first I'll have
to learn what the flags _v_registered and _register mean. :(
I don't even understand what is a "transaction" in the sense
used by the transaction manager.

If I understand correctly, the definition of "transaction"
that you would like to use is one single HTTP transaction,
which lasts from the beginning of a foreign HTTP client
request till the end of Zope sending out the reply.

The question is: is this the same definition of "transaction"
as used by the transaction manager? Why would anything be
stored in ZODB?!? The HTTP "transaction" should not have
anything to do with ZODB database "transaction". The
"versions" that are stored in ZODB, are they FSSESSION
objects?

I'd like to look into all this. :)

regards,

Hung Jung

Calling tags with and without quotes follows mostly the same convention
throughout Zope. A tag without quotes, such as:

  <dtml-var myMethod>

is equivalent to:

  <dtml-var name=myMethod>

This says, "Include the variable with the name myMethod." The alternate
form is:

  <dtml-var "myMethod()">

which is equivalent to:

<dtml-var expr="myMethod()">

This says, "Include the result of the Python expression in quotes,
myMethod()."

In your specific case, dtml-call without quotes is equivalent to
using the name form, and thus does nothing. There is no attribute or
method called subfolder.manage_addFolder(...). Note that Zope would be
looking for this, literally, and would not interpret the period as an
application of a method to an instance.

Using the dtml-call tag with quotes is equivalent to the expr form, and
will thus interpret the period appropriately.

To convince yourself that this is the case, try including a DTML Method
using the expr form without parenthesis:

  <dtml-var expr="myMethod">

puts this in the response:

  <function myMethod at 8071cf8>

If you view this in a browser, you will not see it because your browser
will try and interpret it as a <function ...> tag, which, of course, does
not exist.

Hope this helps.

From my tests I am pretty sure the right dates are stored. It is just the
timeTime() representation of those dates that is wrong.

However, as you pointed out, the methods that provide the representation are
a bit confused over what format the year portion should be in when called.
This,and the fact its something so deeply part of the ZODB makes a fix
something that Jim can do.. =)

Again, greetings...

So I kept looking at what I had, and some things just did NOT look right.

So I fiddled.  I wrangled.  I bashed it with various bits of office equipment. 
And I got it to work!

here is a cutdown of what i used:

    <dtml-in "somQueryHere" size=5 start=qs>
      <dtml-if sequence-start>
        <dtml-if previous-sequence>
          <tr><td colspan="2"><a href="past_orders?qs=<dtml-var previous-sequence-start-index>">
              Previous <dtml-var previous-sequence-size> orders.</a></td>     
          </tr>
        </dtml-if>
       </dtml-if>
      <tr><td>STUFF</td>
          <td>FROM</td>
          <td>ITERATED</td>
          <td>QUERY</td>
          <td>HERE</td>
      </tr>
      <dtml-if sequence-end>
        <dtml-if next-sequence>
          <tr><td colspan="5"><a href="past_orders?qs=<dtml-var next-sequence-start-index>">
              Next <dtml-var next-sequence-size> orders.</a></td>
          </tr>
        </dtml-if>
      </dtml-if>
    </dtml-in>

it's much simpler than the example in the DTML book (IMHO), and it would be
faster in making only ONE call to whatever query it is you're using, not 3.

I'm not sure who is in charge of the DTML reference manual, but if i get a
moment i will be forwarding this code snippet on to them.

Message-ID: <007701bf84f3$98a60640$770da8c0@bbs>

I think it worth to encourage zopelist to move more things to the
client-side by modify a Zope fresh installation.

I found out there are many things hard-coded in
python or dtml in zope's source.

There are some things which can be do better in the client side. For
example, there were many dynamic folder tree writen in javascript which can
be more responsible than the zope tree tag (which the change of the tree
state require the help from server).

I would like to urge zopelists to explorer the client side authoring which
could actually give zope a dramatically change.

1. Remove those hard-coded parameters from the source and placed them in the
folder tree as attributes which can be modified or overwrited by manage
interface and acquisition.

2. Define the basic css (which zope.org have one) as default elements with
the fress zope install.

3. Make the current Zope tag comply with xml standards : they should end
with /> or accept an end tag.

4. Collect open-source javascript codes and convert them into zope products
(like tree).

To build a dict in DTML, try something like this:

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('mydict',{})">

<dtml-call "mydict.update({'e':7})">

<dtml-with mydict mapping>
[<dtml-var e>]
</dtml-with>

<dtml-var standard_html_footer>

Plain python assignment won't work, as a "=" in python is a statement, 
and statements are not supported, only function calls.

to remove a key, use <dtml-call "del(mydict['e'])">

That could be good idea.

What would it add ? But a CSS-method or similar would be a nice addition.

Or even a general TEXT-method, with Content-type: as an attribute, so I don't 
need to write <dtml-call "RESPONSE.setheader('Content-type'. .... for all 
non-html methods

Why ? As has been revealed in several discussions before, it would be very 
limiting for DTML to force compliance to XML (dtml tags inside html tags, etc)

Making it only superficially similar would just confuse people.

If you could integrate it nicely with other parts of zope it would be a
welcome 
addition. But I doubt it would be easy, but if you can come up with a nice 
implementation, I'm sure it would be accepted in contrib.

IMHO this would be a very bad idea, because not all browsers are able to
use javascript. 

for example the tree tag works perfectly with lynx. This is really very
nice, because often we can't do many things with text only browsers, but
the tree tag is very powerful and lynx can use it: it's cool.

IIRC the recommended way was to use

<dtml-var REQUEST>

or perhaps

<pre><dtml-var REQUEST></pre>


It was further recommended to make a method called DEBUG in your root 
folder containing the above and set permissions so that only managers 
could use it.

You may want to check out the Zope-Mozilla initiative (and the related
Model/View discussion), which does something like this. It's on
http://www.zope.org/Resources/Mozilla. As this is Open Source,
contributions are more than welcome.

Another tree difficulty:

I have a tree widget in a page.
When branches are expanded or collapsed the
view you get in the browser moves.

Now I know this is somewhat unavoidable but
can anyone think of a way to limit the effect
for example some way of making the text above
the newly-expanded bit stay still and just
re-rendering that below instead of shifting
everything around?

I am using Interbase 5.6 with ODBC.  It sucks. 2-3 x a week the ODBC
connection gets lost, and the Zope ODBC adapter refuses to reconnect.  

It usually happens after I enter the management screens as well.

I have to shut Zserver down, and restart it.   I think the problem must
be the ODBC driver supplied by Interbase Corp.

I'll probably shift it over to MS Sqlserver as people don't seem to
report problems there.

[ preventing acquisition within a tree-tag ]

After going through the archives my third (and hopefully better tested)
trial with this :-)

In your Extensions directory create an external python method with this
code:

def prev_acqu(self, prop):
    if self.__dict__.has_key(prop):
       return getattr(self,prop)
    else:
       return ''

add it with the id prev_acqu (or anything else you like better) to a
folder in the acquisition path.

In your tree code do:

   <dtml-var "prev_acqu('rubbish')">

If you choose a different id, of course you have to take it here, too. 

Apologies again for jumping into this thread without exactly verifying
my code examples yesterday,

Forget it, its a mad idea.  I was dreaming up some
mad-brained scheme using targets (so eg each
expansion could ensure that the very top of the
page was visible in the browser) but its crazy.
I need a weekend.

That is not "locked up" -- that is the normal "blocked waiting for requests"

Because the FTP server code is in Python, the chances of this 
being a real classic "buffer overflow" (of the sort that can 
start to overwrite unintended memory) is slim (I expect that 
the worst you could do is send something so long that it consumes
all available memory and causes Python to raise a MemoryError).

We should look into the handling of those commands though. I don't
manage the FTP code so I don't have enough deep Zen to know what 
the "correct" behavior is, but it seems that if it's giving a 
false positive then something is probably not being handled 
totally correctly. Can you make an post in the Collector about 
this so that it doesn't get lost in the flow of the list?

Thanks!

You might also look at TimeStamp_yad() (line 117 of the same file in 2.1.4)::

  static double
  TimeStamp_yad(int y)
  {
    double d, s;
  
    d=(y-1)*365;
    if (y > 0) 
      {
          s=1.0;
          y=y-1;
      }
    else
      {
        s=-1.0;
        y = -y;
      }
    return d+s*(y/4-y/100+(y+300)/400);
  }

I _think_ the last line should be::

    return d+s*((y/4)-(y/100)+(y/400));

"every fourth year, except century years, except every fourth century".  Perhaps
the original was "working" to compensate the base 1900 vs. base 0?

Weirdness...

I've almost got mod_pcgi2 setup to serve my entire site fronted by Apache
but I've run into one final snag.

When I access the home page of the site I notice that the BASE HREF
returned by Zope is saying its http://XXX/index.html/

Apparently Apache is appending the Index name for the folder?

I tried Options -Indexes but this didn't solve it.

Anyone have a valid configuration for this situation that I can take a
look at?

Thanks,

It's also worth mentioning that when you do this to call DTML Methods and
External Methods some things automatically get passed in. When you use the
expression form, these things are not passed in. The most important thing is
that the namespace is passed along to DTML Methods and this() and REQUEST
are passed along to external methods. I haven't looked at the python source
to know exactly what is passed in these cases, but you generally will get
what you want if you do this for DTML Methods:

<dtml-var "myMethod(_.None, _)">

and this for external/python methods:
<dtml-var "myMethod(this(), REQUEST)">

   This has nothing with mod_pcgi2 or Apache - it is Zope who adds BASE.
May be you can eliminate it with SiteAccess. It seems you are trying to do
virtual hosting with Apache, and Zope is not capable yet of virtual
hosting, but SiteAccess is one method to helps.

Subject: [Zope] Trouble with dtml-in
Message-ID: <38BFDB65.3AFA8796@lunateks.com>

I'm having trouble with using dtml-in in batch mode.

A syntax like this:

<dtml-in objectlist size=1 start=qs>
  <dtml-var sequence-item>
</dtml-in>

Works properly when qs=1 or qs=0 (treated as 1). Anything more than 1
causes it to ignore the "size=1" setting and loop through all the
elements in the list. The "next" and "previous" parameters exhibit this
problem too.

I can't understand what I'm doing wrong. I'm using the exact code as in
the DTML reference (except for the size of 1).

I upgraded from Zope-2.1.1 to 2.1.4 to see if this problem had been
fixed, but no luck yet.

The only way I can find to get around this is to remove the size=1
parameter and use a <dtml-if "_['sequence-index']-1==qs"> to make the
batch work.

A colleague insightfully commented that while Dynamo has a high bullshit
factor, this is the reason it sells.

Take a look at this screen shot:

http://www.atg.com/news/images/screen-shots/systemconsole.gif

Dynamo is an expensive, closed product with a promotional web site that
smells like a million-dollar penthouse office space, replete with glass
walls and postmodern sculptures. It smells a bit funky, and the people
are possibly evil, but the product is of high quality, and it sells. And
because it sells, many people use it, and because so many people use it,
skilled developers exist in large numbers. Unfortunately, I can't say
the same of Zope.

Speaking of which, SNMP support for Zope would have been nice. Then we
could import the numbers needed to build monitors like the one featured
in the screen shot.

Sorry; I wrote sloppily and shouldn't have said "exported".  This is
the .tgz file produced when you make a distribution of a ZClass-based
product.  For that, you do need to restart Zope -- but the new Product
never shows up.  I haven't yet dug into Zope to see if this feature is
broken, or if something else is going on.

Subject: [Zope] Finding matches between two lists
Message-ID: <3.0.6.32.20000303091400.009538f0@pop.dnvr.uswest.net>

Hey all!

	This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

	---------

	The layout:

	Most of my code is in a Python Product, but there is still a bunch of dtml
used.

	I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

	Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

	---------

	The DTML attempt:

	I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

	<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">
                   <A href="<dtml-var site_url>/<dtml-var id>"><dtml-var
sequence-item></a>, 
                 <dtml-else><dtml-var sequence-item>, 
                 </dtml-if>
              </dtml-in>
            </dtml-if>
          </dtml-in>
        </dtml-with>
    </dtml-if eventnames>


	---------

	The Python attempt:

	So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

    def list_dj_list(self, namelist):
        """ should return a list of names & IDs from a list of names
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rnames = []
        for i in range(len(namelist)):
            rnamelist = rlist
            rname = filter(lambda x,p=self,s=namelist[i] : p.data[x].name
== s, rnamelist)
            if len(rnames) == 0:
                rnames.append('None')
            elif len(rnames) == 1:
                rnames.append(rname)
            else:
                rnames.append('multiples')

        return rnames

	---------

	The question:

	How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

	Thanks for any help!

If I understand you properly, then I think you'll find the Squishdot product
perfect for experimenting with a "real" zope site. Squishdot is a product
that emulates the functionality of Slashdot. You can read about Squishdot
and download it at

http://www.zope.org/Members/butchland/Squishdot

Make sure you install the TinyTable product too for the full tour.

As a post-installation test tool, it would be great to have a sample DTML

Does anybody have such a small collection of DTML pages to donate to the

Funny, I had never heard of Dynamo before you mentioned it here. 
Fortunately, I can't say the same of Zope ;)   I think you underestimate
the actual numbers of people and sites that use Zope.  I also think that
you are creating FUD so that you can get a feature you want to see 
implemented by the folks at DC.  Truly bad taste.

Please no.  There is NO reason to pollute Zope with something as insecure
as SNMP.

Subject: [Zope] 'helper' classes in External Methods
Message-ID: <v04220803b4e59f28a438@[128.240.198.13]>

Can someone give me a pointer to what these helper classes actually 
do? Can I use them to setup lists and dictionaries that will be used 
over the lifetime of the Zope server?

This is an example from an external method that Pavlos posted a while back.

class MCQ:
         ''' helper class for MCQ system'''
         def __init__(self, score):
                 ''' constructor'''
                 self.score = 0
                 self.total_score = 0

What I would like to do is load up a template_lookups dictionary with 
quite a few entries;

for template_id in self.Actors.RENDER.objectIds():
         renderer = eval("self.Actors.RENDER.%s" % template_id)
         template_lookups[template_id] = renderer

Thing is, I need access to the ZODB in one of my methods later in the 
module and so the above code doesn't work (too many 'selfs'!).

Anyone got any ideas?

Well, I am doing Virtual Hosting via Apache, but I'm only running one site
per instance of Zope.

Isn't this possible with pure mod_pcgi2?

Note that the servers listed as runinng Zope on Netcraft, are those that run
straight ZServer. Those sites that run Zope behind Apache, IIS, Zeus, or any
other webserver, will be listed under those webservers. So, a small
percentage of the number of Apache sites on the web, runs Zope.

From my personal expirience, I find that a lot more people run Zope behind
Apache, instead of pure ZServer. So, the number of Zope sites is a
significant factor higher than the 300 listed by Netcraft.

For an example, go to:

  http://www.netcraft.com/whats/?host=www.zope.org

You'll see that it is listed as running Apache (which it is).

Message-ID: <38BFF7BB.8EA2DA2B@vt.edu>

Hi, ed.

I think I am a bit dense today, so could not quite understand completely
what you are doing, but

If you want to find matches between lists, there is a cool thing in
Python that can possibly help you.  

Let's say I have two lists, list1 and list2, and I want to know what in
list1 is in list2, which is I think what you are going for.

list1 = ['n', 'b', 'r']
list2 = ['f', 'd', 'b']

def intersect(lista, listb):

    tmp = []
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp.append(anitem) #if there, append to the temp list
    return tmp                 #return the temp list

print intersect(list1, list2)  #should be ['b']

If I want no dupes, (if 'b' is in list1 twice, it will be returned
twice) I probably would use a dictionary instead of a list and return
the keys, e.g, 

def intersectnodupes(lista, listb):
    tmp = {}
    for anitem in lista:       #iterate through lista
        if (anitem in listb):  #check to see if the item is in listb. 
This is the cool thing.
            tmp[anitem] = 1    #if there, throw it into the doct
    tmp1 = tmp.keys()          #get the keys (arbitrary order, alas!)
    tmp1.sort()                #the keys are in arbitrary order no
longer
    return tmp1                #return the unduplicated list

In DTML, you can use the 'if athing in alist' thing too:

<dtml-call "REQUEST.set('list1', ['n', 'b', 'r'])"> <!-- or use your own
lists -->
<dtml-call "REQUEST.set('list2', ['f', 'd', 'b'])">

<dtml-in list1>
<dtml-if "_['sequence-item'] in list2">
<dtml-var sequence-item> <!-- do something with the things in list1 that
are in list2 --> 
</dtml-if>
</dtml-in>

Message-ID: <3.0.6.32.20000303184315.0093e620@poirot>

Hi,

I'm once again trying to get further in my test products.

* I've created a catalogAware ZClass, called KBItem
* KBItem contains an external method with id manage_afterAdd

Now, I can add KBItem instances in Zope without problems, BUT!

when having a ZCatalog inside a folder with the id Catalog and then try to
create a KBItem instance, I get following error (where testje is the id of
the KBItem I try to create) :

Zope has encountered an error while publishing this resource. 

           Error Type: ValueError
           Error Value: Uncatalog of absent id 'TEST_Folder/testje'

Help! I don't know what I'm doing wrong or what is happening!
What does it mean and what can I do?

Thanks in advance,

Tom.

if you have 2 queries one of which returns tuples containing events and usernames,

Subject: [Zope] Finding matches between two lists


Hey all!

This question went by last month without a reply, so I am going to try it
again.  I've also gotten a bit closer to the answer on my own.

---------

The layout:

Most of my code is in a Python Product, but there is still a bunch of dtml
used.

I have a class called "person" with a string variable called "name",  and
a class called "event" with a list variable called "eventnames".

Now when a addEventForm is filled out, then the viewEventPage is called, I
want all the people listed in "eventnames" to have a link to thier home
page if they exist.

---------

The DTML attempt:

I could never get this to work correctly.  Becuase it is looking through
two lists, the code causes the "eventnames" to be dispayed once for each
person listed.

<dtml-if eventnames><BR><BR><STRONG>Featuring people :</STRONG>     
        <dtml-with "PARENTS[0]">
          <dtml-in personValues>
            <dtml-if "meta_type == 'SRPersonPost'">
              <dtml-in eventnames>
                 <dtml-if "_['sequence-item'] == name">

The Python attempt:

So I tried to change my strategy, and build a method to find the matches,
and return the list with the ids (if the person is listed) or a 'None' if
they are not listed.  I haven't been able to figure out what is going wrong
with this.

    def list_dj_list(self, namelist):
        """ should return a list of names & IDs from a list of names
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rnames = []
        for i in range(len(namelist)):
            rnamelist = rlist
            rname = filter(lambda x,p=self,s=namelist[i] : p.data[x].name
== s, rnamelist)
            if len(rnames) == 0:
                rnames.append('None')
            elif len(rnames) == 1:
                rnames.append(rname)
            else:
                rnames.append('multiples')

        return rnames

---------

The question:

How can this be achieved?  I don't have a preferance over dtml or python,
but it seems like a python method is the proper way to do it.

Thanks for any help!

Hi Tom,

This might be because the CatalogAware class uses the manage_afterAdd hook
itself (CatalogAwareness.py).

In _your_ manage_afterAdd(self, item, container), try this (untested):

def manage_afterAdd(self, item, container):
      # do whatever want to
      CatalogAware.manage_afterAdd(self, item, container)

Hope this works.

Great idea!

However, no I get this error :

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: CatalogAware

Do I've to place somewhere an import of the CatalogAwareness library?
I'm afraid my knowledge of Python is to low to solve this correctly. Any
ideas?

Tom.

Hi,

I installed Zope 2.1.4 on my RedHat 6.1. I wanted to change the password given
by the installer. I tried : 
python zpasswd.py -p=mynewpassword access

Everything seems ok. I have new file called access which looks like the older
one except for the 'password' part.

1 - Do I need to restart zope in order to have the new password be effective.

2 - Even if I restart zope, i cannot use my new password. However if i replace
the new file called access by the old one, i can acces to the zope management
screen.

What have I done wrong?

Message-ID: <3BA3A8B61E4ED211ABB900A0C9615FE639C822@sev-mail.gtri.gatech.edu>

Okay, I'm new to Zope (3 days), but I was having such success with some
simple things that I thought that I could handle something tricky - I've
been working at it for a day now.

What I would like to do is present two selections (Division and Team) that
are populated from an ODBC connection.  I can do the population fine,
normally; but the trick is that I'd like to have the Team selection
dependent upon the Division selection (on the same web page).  I realized
that I couldn't do this on a simge form (or can I?), so I've assigned the
two selections to two forms.  I'm putting the two forms on the same page for
aesthetic (stubborness?) reasons.  Here's the code for the first form:

<form action="index_html" method="get"> Division:
  <select name="division" width=30 value="">
    <dtml-in sqlShowDivisions size=50 start=query_start>
      <option> <dtml-var age_group>
    </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>


This part works fine.  When I submit the form, the same page is regenerated
(with the 'division' parameter passed in).
One of my many failed attempts with the second form (which is also in
'index_html') is as follows:

<form action="TeamSchedule" method="get">
  <dtml-var division missing="Undefined"> Team:
  <select name="team" width=30 value="">
     <dtml-in sqlTeamsInDivision size=50 start=query_start>
        <option><dtml-var name>
     </dtml-in>
  </select>
  <input type="SUBMIT" value="SUBMIT">
</form>

my sqlTeamsInDivision has 'division' as its only parameter.

When the user first enters the document, he gets an KeyError on 'division'.
I understand why this is so (the division parameter doesn't exist yet), but
I can't seem to work around it .

I tried changing the sql parameter to divisionname and changing the
<dtml-in> tag to:

<dtml-in expr="sqlTeamsInDivision(divisionname='<dtml-var division
missing>')" size=50 start=query_start>

and the error goes away, but the returned list is just blanks.  How should I
be handling this?

Also, when this form is submitted, it calls TeamSchedule with the 'team'
parameter, but I need to also pass the 'division' parameter.  How do I do
this?

Thanks in advance.

Subject: [Zope] Installation trouble on Solaris 2.6
Message-ID: <NDBBLONFDKEIFDBOFGJMCENCCCAA.ztf@one.com>

Hi all,

I'm trying to install Zope from source on a Solaris 2.6 system,
and I'm running into problems.

When I try "./start", I get the following error:

$ ./start
$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

PyImport_ImportModule: referenced symbol not found

I am new to Python, so it's less than obvious to me what is going
on here.  It looks like the ExtensionClass module is failing to
import, but I have no idea how to go about fixing this.

[Yes, I know about the precompiled Solaris 2.6 binary.  However,
I eventually will need to get this running on a Solaris 2.5.1 system.
Also, as far as I can tell, the binary release is not set up for
Apache integration, which is something I also need to do.]


Thanks in advance,

I think it is not a good idea to define classes in external methods. It is
better to define them somewhere in Shared (see the directory DC under
lib/python/Shared for example) and import them in your external method. 

import Shared.Tony.helper

 They can be very handy especially since python is way more elegant and
easy for complex logic in relation to DTML.

Not sure. need some more info. Did you try to use getattr to get to
object?


tmp=self.Actors.RENDER
renderer=getattr(tmp,template_id)

What kind of object is template_id?

People did report this bug elsewhere on the list. Apparently we're waiting
until monday when Jim Fulton can take a look at this. They're pretty sure
it's just a display problem and not something wrong with the object database,
but they want to make sure and check with Jim.

If you are sure that you can get along without the BASE HREF in a virtually
hosted (or other) Zope page, there is a way to fool the ZPublisher so it
doesn't include the obnoxious tag.  Just put

	<base dummy=dummy>

near the top of your method.  This turns out to be enough to fool the fairly
droidal scanning code into thinking that no additional BASE tag is needed.
Since it's an unknown attribute it should be a total no-op in browsers.  Of
course they could write a smarter parser in a future release so caveat
Zopor, but it works for now.  I wish they hadn't relied on that tag to begin
with.

Okay, never mind.  I figured it out.  I needed to use:

 expr="REQUEST.has_key('division')

to determine if the 'division' has been defined.

Also, the passing of multiple variables was obvious - just define a hidden
input field.

Thanks, anyway.

Message-ID: <007c01bf8553$1d6fa8e0$7b5addc7@laptop>

KM|Net News is a Zope through-the-web Product that allows you to post
news-style articles on your site. 1.1 is easier to install (because it
creates its own Catalog and does not have any external methods) and now
incorporates linking to external sites for more weblog-style publishing.
(KMNN is still different from Squishdot in that there are no discussions
attached to the articles and has different features for placement of the
articles within the article listings). You can see KMNN 1.1 in action at
http://www.byproducts.com

KMNN 1.1 also includes a new "contrib" method for trusted people to
contribute articles without review.

*** KMNN 1.1 requires PythonMethods. ***

You can get KMNN here:
http://www.zope.org/Members/tazzzzz/kmnn

If you're upgrading from an earlier KMNN, you may want to use the "Restore
Defaults" tab to "Rebuild Catalog" and restore "incoming.html". The new
incoming.html adds the fields for external articles.

This will probably be the last major revision of KMNN before the PTK.

Subject: [Zope] Logging users in Zope 2.x (second try)
Message-ID: <38C036C6.2300C61C@tm.ee>

How should I configure logging to get usernames into Z2.log

I first hoped to get it from Apache's access_log, but it saves 
username only when doing user authentication itself.

Then I thought that Zope at least would log it and migrated the 
site to Zope 2.1.3 to get logging support. 

Unfortunately it does still not log usernames and I have not 
found the place where I could turn it on.

Also the format is buggy:

Apache access_log:

193.40.215.135 - - [11/Feb/2000:08:29:55 +0200] "GET / HTTP/1.1" 200 2673

Zope Z2.log

127.0.0.1- - [11/Feb/2000:19:04:46 +0300] "GET /misc_/OFSP/dtmlmethod.gif" 200
1000

the bug being the missing space after the IP address.

what I was hoping for would have looked like:

127.0.0.1 - superuser [11/Feb/2000:19:04:46 +0300] "GET /manage" 200 1000

It looks like your dynamic linker cannot find your python libraries. 
There is an environment variable that you must set so that the linker
can find any libraries needed by shared library modules like
ExtensionClass.so.  I believe the env variable beings with LD_.  Do an
'env' (in bash at least) and look for something like that.  I never
remeber it cuz in Linux you just edit a file.

The binary will work fine with PCGI (Apache integration).  Whether it
runs on 2.5.x I don't know.

Hi Tres, Hi Jack,

Thanks for the infos/repost.
Is there no way to control UW IMAP to look for a specific folder in each
user's home dir for the INBOX root? Something like the way
http://host/~username/ mapping works in apache?

If not, then I'll add this instruction to the upcoming FAQ for
worldpilot, since this is the no.1 question up to now. (Jeeze, looks
like I'll have to install UW IMAP myself afterall, too.)

Cheers,
Ryan

In Amos Latteier's "creating XML Applications With Zope" at
http://www.xml.com/pub/1999/12/zope/index.html


There is an example that uses a Zcatalog.

He says to enter this into the expr field of the "Find Items to Zcatalog":

getNodeName()=='entry'


and click find.

When I do this with my own version, or even his version 
Zope gets this error:

Zope has encountered an error while publishing this resource. 

           Error Type: NameError
           Error Value: Eval


it has to do with that entry in expr.

Is that a typo?

Sorry, coming in late here. The Env variable you need is LD_LIBRARY_PATH. Mine
is set to
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib:/usr/local/lib/mys
ql

(I know this 'cos I did a new Zope install the other day on an account that
only had 
LD_LIBRARY_PATH=/usr/local/lib/:/usr/lib:/usr/local/ssl/lib
I started the Zope server under that account and found a broken MySQL product,
with an error message saying it couldn't load libmysqlclient.so.6. I had cold
chills going down my back for a looong few minutes....shudder)

Subject: [Zope] Assorted Zope problems
Message-ID: <20000303164457.A1221@velocity>

Hello-

I've been trying to get our existing Zope server (previously with ZServer
handling http) under Apache.  Here are some problems I ran into:

1. My biggest problem was that Zope uses the SCRIPT_NAME environment
   variable to construct it's notion of the base URI.  Unfortunately,
   SCRIPT_NAME gives the actual script name, not the URI.  So if you
   do a ScriptAlias, or any rewriting inside Apache, this isn't necessarily
   valid.

   An adequate solution seems to be to change
   PYTHONHOME/lib/python/ZPublisher/HTTPRequest.py line 211, to use
   DOCUMENT_URI instead of SCRIPT_NAME.

2. I couldn't get Apache with FastCGI and Zope working reliably.  On about
   1% of requests, garbage would be returned, resulting in random broken
   images or pages full of gibberish.  This is with the Oct 06 snapshot of
   FastCGI, compiled into Apache-1.3.12.

Anyone else seen anything like this?

Ed

Just curious, what does the result of a LIST with "~/Mail" look like on
UW IMAP?
What is the top node labeled as? 
I guess I could add a parameter to control the behaviour of the LIST
call.

"1%?  You were _lucky_!" (in my best Yorkshire accent).  I was getting
a much higher rate of errors (admittedly, I was only using the management
screen at the time as I was just starting out with Zope), but I ended up
switching to mod_pcgi2 to cure these problems.  The problem has been
mentioned before on the mailing list, but I'm not sure if a solution has
been found.

Platform is (for data point purposes): RedHat 6.1, Apache 1.3.9, Zope
2.1.4 and fastcgi Oct06 snapshot.

I want to write an object that can be traversed by ZPublisher.  The
goal is so I can write URLs like thingyForwarder/45/display, to get an
object corresponding to thingy #45, and call its display() method.

What's the Zope Zen way of doing this?  Implement an __of__ method for
acquisition?  Implement a __bobo_traverse__ method?  Make
thingyForwarder a Folderish object and implement all the folder
methods?

Subject: [Zope] Client-side Zope
Message-ID: <002501bf856e$7aee5640$770da8c0@bbs>

Continue to moving more job to the client, There will be more for Zope to
perform:

1. There will be necessary to generate various section-specific temporary
objects for CSS, DTD and Scripting files, framed or embeded html.

2. There will be necessary to support java or javascript access of zope in
the client.

In the first requirement, I would like to suggest an machenism to create an
section specific temporary object (which zope create the unique name and
substitute it) which dtml is able to write to it. The new object can be just
a new dtml-document. As in the following

<dtml-object dtdobject>
<dtml-object scriptobject>
<dtml-object cssobject>
<script lang="javascript" src="<dtml-var scriptobject>">
....

<dtml-write target=scriptobject>
function <dtml-var uniquevalidfunctionname>(){
   ....
}
</dtml-write>

I don't known about the solution of the second request.

In the long run, zope might encourage separate of control and data. The
current opening all tags in one dtml-method and closing them in another is
very dangerous if the control get complicated. I would like to suggest DC
consider a xslt like syntax which can also be used in server side xml to
html conversion if the client do not support it.

If zope is going seriously to the international market and xml, then unicode
is important in the core level.

I think __bobo_traverse__ will do what you want. You can look at the local file
system code in LocalFS.py as an example.

Nope, a bug.  The fix is in CVS but failed to make it into the 2.1.4
branch.

Put this line just after the license in
lib/python/Products/ZCatalog/ZCatalog.py

from DocumentTemplate.DT_Util import Eval, expr_globals

and it will work.

Take yer pick.

ZPublisher will try the following methods to traverse an object, in this
order:

__bobo_traverse__(request, name)

  Request is, suprise, the REQUEST object, and 'name' is the path
element ZPublisher is trying to traverse to.

getattr

  ZPublisher will try and get the subobject by 'name' with getattr.  If
this fails with an Attribute error then...

getitem

  ZPublisher will try to get the subobject by 'name' with getitem.  If
this fails, you get a 404.

One subtlety to be aware of is that __getitem__ seems to be called *after*
acquisition is given a crack for reasons that elude me. Since I've never been
able to get an explanation of how to use __getattr__ without blowing up the
acquisition machinery, this makes __bobo_traverse__ the only foolproof way that
I know of for hooking traversal. Someone please correct me if I am wrong.

The reason you have not heard of Dynamo is that Dynamo isn't being
hyped; Zope is.

There are other, non-Zope solutions out there, some of them quite solid.
I like to keep an open mind, and so should you. There are, indeed, quite
a number of people who have heard of Dynamo but never heard of Zope.

While my statistical data is entirely non-existent, I'll wager that
Dynamo-awareness exceeds Zope-awareness by a factor of at least two. ;-)
This isn't necessarily something to get upset about, and anyway I
believe, and hope, that the difference is shrinking.

Just a bit of background since you're accusing me of FUD.

Dynamo drives many of the web's most popular sites, and is in direct
competition with Zope, sharing the application server space with
contenders such as SilverStream, Sybase, Vignette, Jade, and many
others. Along with Vignette, Dynamo is one of the most successfully and
widely employed app servers solutions in existence. Whether this is a
good or a bad thing I'll leave for you to decide; I don't like Dynamo,
but I acknowledge its technical edge on Zope (and other solutions) in
several areas, such as clustering, reporting, personalization services,
e-commerce services, stability, and raw speed.

As an artifact of Dynamo's platform of choice -- Java -- there is
indirectly a "virtually limitless" expertise on Dynamo. If you know your
Java and your Enterprise JavaBeans, you already know Dynamo, and
stepping into your Dynamo shoes will be easy. Compare that to stepping
into Zope's multiple zens: acquisition, DTML, objects, Python. Note that
I'm not arguing against Zope here, which has a self-inflicted and
justified learning curve. However, managers will not necessarily respect
this difference in philosophy: The cost of training a person in the arts
of Zope will be measured against the cost of hiring an already-trained
Java wizzkid, and -- at least right now, today -- Zope will lose.

This situation has nothing to do with open vs. closed, either. Just like
Zope we're talking about proprietary (as opposed to standarized -- DTML
may be open, but it's still proprietary) technology. The fact that Java
is more widely established, and evolving faster, than Python is
unfortunate and outright infuriating, but right now that's how the cards
are dealt.

Dynamo also costs a lot of money. For small businesses, it costs too
much. A heavy-duty support contract with Digital Creations also costs a
lot of money, but you have a choice. On top of that, Dynamo is
open-ended but not open -- there is no source distribution.

My point? Zope already has a foothold in the small-time web site segment
of the market. However, big people wield big swords, and Zope, despite
its many powerful features, is not big enough for truly big things.

This is a two-part problem. The first part is that Zope's bullshit
factor is too low; it's not flashy enough to convince a senior manager
that Zope has enough clout for their business. It's a purely aesthetical
apprecation of Zope's poor-man, open-source philosophy, and the fact
that Zope does not offer a comprehensive monitoring system with a ticker
bar providing useless but impressive information does not fare well with
those who like to be bullshitted. We tech people know better, we know a
shiny surface tells us nothing about the engine underneath, but we tech
people are not holding the crucial component -- those big brown bags of
money.

Now, the second part of the problem is that underneath Zope's lacklustre
but entirely deceptive surface lies a powerful engine with scalability
problems. So far the only way to scale properly with Zope is a
combination of a load-balancing clustering system (eg., TurboLinux'
TurboCluster Server, which I can personally vouch for -- brilliant stuff
-- or Linux Virtual Server) with Digital Creations' ZEO, of which I've
only read about. There are Zope sites out there that are suffering
scalability problems (I won't mention specifics, other than that the
project I'm involved in is one of them). The problem is real, and
intrinsically related to Python. I wish I fix Python rather than sit
still and bitch about it; I periodically express my dissatisfaction with
Python's lack of performance, and I have certain ideas as to how to
improve it, but a research project like this would take time, of which I
can currently allot none. So instead I just bitch. ;-)

Finally, as for DTML being proprietary, Zope desperately needs native
support for XSL/XSLT as an alternative transformation language. I think
it was Michel who spoke vaguely of this being considered incorporated
into a future version of Zope. (At one point I planned doing an XSL
product, but I have not yet had a project to fund it with. So I'm not
just bitching here.) We also need better in-line scripting capabilities
than currently offered with External Methods and PythonMethods. This to
fight the creeping and ever-expanding notion that Java (replacing
Smalltalk) is the chosen, possibly even pre-destined, language for app
servers and middleware. Try to find an OODBMS, RDBMS, or application
server nowadays that does not use, or plan to use, Java as its
fundamental extension mechanism. I can think of a few, but they're few.
If you want to talk about FUD, you've got it right there.

Anyway, just my two cents.

Then please offer us an alternative, open, standarized interface to
monitoring data. The fact that SNMP in itself is insecure has little, if
anything, to do with whether Zope should be "polluted" with such
support.

An alternate route might be to have Zope export necessary variables
through a well-defined XML DTD, and then provide the necessary tools to
convert this XML output to SNMP, although supporting SNMP traps this way
would be difficult.

Perhaps supporting Performance Co-Pilot
(http://oss.sgi.com/projects/pcp/) would suit you better. Unfortunately,
PCP is probably not -- at least not now -- portable to Windows NT. In
fact, I'm not sure whether PCP will exist outside IRIX and Linux for
some time yet.

As far as pollution goes, assuming Zope exports the appropriate data --
in whatever form -- then support for performance/monitoring/management
APIs such as SNMP, PCP, WBEM, and to a lesser extent PDH, aren't
difficult to isolate into add-on products.

Thanks, Tony and Michel.  Unfortunately, LD_LIBRARY_PATH doesn't
seem to solve it, which is really puzzling.

The gory details are:

My base Zope installation is /usr/local/zope/Zope-2.1.4-src.  So,
ExtensionClass.so is in /usr/local/zope/Zope-2.1.4-src/lib/python.
My LD_LIBRARY_PATH is
/usr/local/zope/Zope-2.1.4-src/lib/python:/usr/local/lib:/usr/openwin/lib,
which ought to pick up ExtensionClass.so.

Anything else which would cause the import to fail?  I tried setting
PYTHONPATH too, in desperation, but it doesn't seem to make any difference.


Thanks,

Zach Frey


P.S.: I did try the binary distribution on Solaris 2.5.1, and can
report that it doesn't work.  Zope fails to start up with an unresolved
symbol error, so it really does require 2.6+.

If you consider separate code and data. If you think about putting
XMLDocument in real use.  This is one of the possibility:

using an xmleditor, the user can save the xmldocument to zope server as zope
automatically make all parts of the document reusable as zope object (is it
all what zope about? making a document into many small parts as each of them
be re-usable object?) This is process by zope automatically, the author do
not required to do extra works. The author can edit the document or part of
it and view the final result if the xml-editor support this.

To make this better, the author can embed dtml code in the xml document,
which make the document be active and live. You may have a system
automatically updated. Isnt it what zope designed to be?

The document inside zope can have multiple view as we can have dtml-methods
to transfer them into different view: html, xml+xsl+css, pdf, doc, etc...

If dtml syntax is not xml-complience, all of these will not happen.

A deeper change is to make dtml syntax more xsl like. I.e., make it block
oriented. So, the author is forced to code in good manner, instead of the
opening and closing tags were spearated into many places which I think is
very bad for maintenance.

I believe the problem is with ZServer/FCGIServer.py.  If you pull the latest
version from CVS (1.7), the problem should go away.  I had this problem a
LOT when I first started using it, but after getting the latest
FCGIServer.py (1.5.4.1 at the time), the problem went away completely.

Actually, what I am working on is abstracting that out. :)

What I _want_ to do, is to allow you to customize how you store the
dynamic data (like hits, clicks, remaing hits/click, etc.); whether it
be in an RDMS, Zope, File, whatever. I think I've got a pretty good
handle on it ... on paper (yes, I still do much of my code-writing on

I was thinking of an XML-RPC cronscript, though that wouldn't work on
windows boxes(?). Perhaps the recent Scheduler product will mature
enough, soon enough.

Subject: [Zope] PostgreSQL money weird problem
Message-ID: <38C06A0A.1DD2F6BF@uol.com.br>

Hi,

I'm with a weird problem with a report from a SQL database. I have a
field of type 'money', and every time I use it in a SELECT query, it
returns 0.00, doesn't matter the actual value of the field (in the
example bellow - the 'test' of the query -, the field Valor is of type
'money'):

 Id | Idcliente | Data       | Valor
  1 | 11        | 03-03-2000 | 0.0
  2 | 11        | 03-03-2000 | 0.0
  3 | 11        | 03-03-2000 | 0.0

SQL used:

select *
from compras
where idcliente=11

Running the same query on the interactive client, gives the value of
money:

credito=> select * from compras where idcliente=11;
id|idcliente|      data|valor   
--+---------+----------+--------
 1|       11|03-03-2000|R$50,00

 3|       11|03-03-2000|R$15,00 
(3 rows)

I'm using Zope 2.1.2, ZPyGreSQLDA, and PostgreSQL 6.4.2, running in a
Conectiva Linux 4.0 (kernel version is 2.2.5).

The definition of the class compras is:

Hi Ryan,

I thought I'd jump in on this since it gives me a good reason to learn a little
more about how IMAP works. ;-)

I logged in via telnet to my test system and determined (with some help
from the IMAP4 RFC) that the command being executed is 

LIST "" *

Since the UW IMAP server logs the user into their system account I can only
assume that this drops them into their home directory. If I execute the
requested command it will return nothing unless a Mail directory exists in the
users subdirectory. (I have one user setup this way from earlier tests and one
without the directory.) 

Executing the command LIST Mail * returns the same as LIST ~/Mail * for the
user with a Mail directory. 

I will attempt to do some checking on the functionality of the .imaprc file that
is sort of documented and see if this can be used to work past the problem.

Subject: [Zope] FYI: large files & linux.
Message-ID: <38C0AF01.C9887838@imeme.net>

Zopistas,

I was trying to get large file support on linux.  I succeeded, but only
partially.  Steps:

1. Download and install a kernel greater than 2.3.27. 
   It has the large file patch built in.

2. Reformat ext2 partition with 4k blocks:  
   mke2fs /dev/hdaX --block-size 4096
   the maximum filesize for ext2 depends 
   on the blocksize: with 4k blocks, it's 1TB.

3. Use Glibc 2.1.13-5 from debian potato.  
   unknown whether 2.1.12 from the gnu site is sufficient.

4. compile python 1.5.2 like so:
   CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" OPT="-O2 $CFLAGS"
\
 ./configure --with-threads

5. Now you can make files up to 4096 MB in size.  Why no bigger?
   I have no idea.  For me, at least, it means 1/2 as many zopes.

Optional step:

Wait.  In a few short months Linux should handle large files natively.

Ok, so you can't use the Zope distn that has a precompiled Python bundled (it
seems).

Try setting LD_LIBRARY_PATH as above and recompiling your Python source
distribution.

I know I had a real pain getting Zope-src distns running under Solaris (and
then found that our big expensive Sun Iron was half the speed - in pystones -
of my iMac! ...grrr) - but it can be done. 

HTH?

I would prefer this scheme too. You are breaking up a document into constituent
'blocks' in a different way than it is done presently.
I suspect you may get not only this but more in the future. There have been
similar thoughts going on in people's minds:

You'll have to call your DTML Method in a special way. When caling a DTML
object with <dtml-var name=DTMLMethodOrObject> this is automatically taken
care of. but when using it in the above way, you have to do this by hand:

  <dtml-in "creditCardSelections(_, _.None, *other arguments*)">

You now pass in the namespace as well, so your DTML knows how to access
other Zope Objects. This _will_ change in the future, BTW, this will be
automated for various reasons. You then won't have to think about all this
anymore.

Have alook at the following How-To, and espcecially the list referrenced at
the bottom of it:

  http://www.zope.org/Members/Pam/DTMLScripting

They will introduce you to the more advanced ideas of DTML scripting.

I've just moved from qlcomm.com to the current location. Your DNS server
must still be using the cached entry. Should be fine in a little while.
You can mail me at jace@radiolink.net until then (the address I used to

Here is what I use:


<dtml-var standard_html_header>

<dtml-with aq_parent>

<dtml-in "objectItems(['DTML Method'])" previous size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var previous-sequence-start-number>">
(Previous <dtml-var previous-sequence-size> results)</a>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" size=1 start=page>
     Document id: <dtml-var id>
</dtml-in>

<dtml-in "objectItems(['DTML Method'])" next size=1 start=page>
<a href="<dtml-var document_id><dtml-var sequence-query
>page=<dtml-var next-sequence-start-number>">
(Next  results)
</a>
</dtml-in>

</dtml-with>

<dtml-var standard_html_footer>

-----------
This doesn't work. When page=1, it's fine. When page >=1, dtml-in loops
all the way from "page" to the end of the list. I don't know why it's
doing that. The "dtml-in next" loop also does the same thing.

To explain the setup: I have a ZClass called "Article" based on
ObjectManager and set to accept only DTML Methods and Images. The above
code is in a DTML Method called "index_html" placed in the ArticleClass
(not when being implemented). I had the same annoying problem when
working with the results from an SQL query instead of objectItems. My
workaround then was to leave out the "size" parameter and instead use
dtml-if to compare sequence-index with page. It's ugly but usable when
there are only 4 or 5 pages.

I filed this in as a bug about an hour ago. Hope it gets resolved
quickly.

I've never used the DC Shared folder before. I've had a look in there as you
suggest and found some interesting things there. Time to read the docs on this

Definitely. I'm now using the XXX PythonMethods that Evan Simpson contributed

Sorry, I should be more specific. The above code is in a method - def
supercascade(self, tag_id): which is called from Zope with a query_string,
tag_id=231441.

That code works, but I need to load up the renderers everytime supercascade is
called. I'm looking at the helper classes to see if I can't load up the
template_lookups array once. Having said that, supercascade isn't called
anywhere near the number of times that make_html (the method that generates
the HTML for display) is, so it's possible that I'm flogging a dead horse
here.

> tmp=self.Actors.RENDER
> renderer=getattr(tmp,template_id)
> 
> What kind of object is template_id?

It's a DTML document of the form (this example has id = lecture_info);
---
<hr>
<p class="<dtml-var class>"><dtml-var content null="&nbsp;"></p>
---

make_html then has a snippet in it so;
try:
    template_str = template_lookups[theclass]
    template = DocumentTemplate.HTML(template_str)
    theresult = template(self, content=content, src=src, thetag=thetag,
level=level, the
class=theclass, header=header)
    return "<!-- theclass [%s] thetag [%s]  -->" % (theclass, thetag)  +
theresult
except:
    pass

which will then render the HTML appropriately. The *really* neat thing is when
you have more complex DTML in the template that has ZSQL calls etc. 

It works well, but I want to speed it up a bit - it can take up to 6 seconds
to render a 100k document, and if I've understood my Zope architecture
correctly, thats one thread used up (and I'm only using the default thread
count - I think it's six) until the request has finished. I'm sure that
previous messages on the list have implied that it's not worth changing the
number of threads to something like 32-64, but I'm not sure.

That's my main problem, people are hitting the site and generating lots of
requests that are in the >1 second range. With our Apache servers, we just
spawn ludicrous numbers of httpd processes and don't worry about it. Zope is a
different kettle of fish and I need to think differently about it.

Many thanks for your help Pavlos, I feel things are a quite a bit clearer now.

Of course.  Some people suspected a "user error" at first, though. 
:-)

Anyway, I wasn't reporting a bug anymore,  I found the probable 
cause in the TimeStamp module, in the meantime, and reported 
that findings, and a way to fix it, here.

Lets hope for the best. :-)

PS: people have asked my for the modified TimeStamp module in 
(TimeStamp.pyd on my NT system) in private mail, but I'd prefer to 
have them wait for an "official" fix.  Poking around in the object data 
base source isn't something to take lightly.

   How many items are there in objectItems? May be you need orphan=0?

I was very comfortable in my cozy PHP/MySQL world, until I saw Worldpilot.
I HAD to finally break down and
install Zope so I could have this.  Needless to say, my python/Zope skills
are a little lacking at this point.  I could
use some help.

Everything is installed and working great, except for a couple small
problems with Worldpilot.  I'll detail the most
significant first, and see how we do.

When I try to send mail, I get a Zope error with the following traceback:

The problem is obviously (to me anyway) that the call to publish in the def

getting one

I'm not sure I understand why, as this is a bit beyond my current
comprehension of python at the moment.
A gentle push in the right direction would be appreciated.

I have a DTML Dccument, stx_about that looks something like:

I will have to concur that Philip's book is a very good read. In
addition to his book he has great suggestions for your library of other
books. There are many of his ideas I think are wonderful, however I do
have some philosophical disagreements on others.

Some of his views of computers and programming are somewhat cynical even
if based somewhat on fact.

His version of scalability of which he focuses on a lot is basically
throw lots of money at it.
Start off with a highly scalable, multi-threaded, high quality webserver
with an embedded scripting interpreter. In his case AOLserver with Tcl.
He openly hates Tcl, but doesn't work towards using the language he
likes where he works. Further more he thinks doing so is folly. (my
interpretation) He states relational dbms are the only way to store
data. Other technologies aren't as mature or capable. And on relational
dbs only Oracle is sufficient. With others you are taking unnecessary
risk.

So to scale with Philip you develop with AOLserver/Tcl/ACS, buy big,
expensive hardware, buy big expensive database. ie: throw lots of money.
Since he prefers everything to be in a single machine you can only scale
up processors so much before the $$$ start escalating. Price an 8
processor anything versus a Linux cluster of 8 machines.

This is not enabling for the little guy. Yes I know of the ACS port to
PostgreSQL. I think that's great. However it is going to be a step
behind ArsDigita/ACS because it does require porting to become
PostgreSQL able.

He has disparaging remarks about app servers, many of which are true.
However, I do not necessarily believe that learning Zope/webserver is
more difficult than learning AOLserver/ACS. And when you've got Zope
you've got Python instead of Tcl. For some of us, we like that. :)

As a prodigal son here, I embraced Bobo/Zope early, became concerned
about scalability, wandered the websphere, and have come back home. I
have looked at Java/Servlets/Enhydra, AOLserver/ACS, etc. I decided to
follow my heart. I like Python and Zope. I like the Python and Zope
communities. This is where I want to make a difference and contribute.

Zope can enable the idea person, the little guy with a twinkle in his
eye and a big dream to pursue.

Sure it may not "currently" scale as easily as AOLserver/ACS for big,
busy sites. However, I think it is being worked on. I think that there
are options within Zope, Digital Creations. To a very large extent
Philip solves scalability with $$$dollars.

With Zope you can still throw $$$dollars at Oracle. You can also throw
some at Sybase, or whateverBase you desire. If that gains you
scalability or the ability to sleep at night it's available. With
ArsDigita/ACS the only supported option is Oracle.

If I believed throwing $$$dollars to solve scalability was required. I
would much rather throw $$$dollars at Digital Creations. Instead of a
$20,000 to $500,000 on up license of Oracle which is per machine, per
website, and potentially expires. Instead of requiring buying big, big
hardware for $$$dollars. Throw the money towards Digital Creations or
other Zope or Python developers to solve the issues which hold
Zope/Python back. In the end you will have helped build a bigger, better
open source software solution.

As a little guy with ideas and dreams, this is my view. By the time a
website grows enough to run into scalability and performance problems
with Zope it could potentially be making enough $$$dollars to contribute
to solutions. Try that with AOLserver/ACS/Oracle, start with $$$dollars
and then hope for the best.

My other thoughts wandered into employment. When I master either Zope or
AOLserver/ACS, would I rather work for ArsDigita (yes, they pay well) or
Digital Creations, if an opportunity presented itself in the future. As
I know both are growing companies. I like Digital Creations. :) 

On a side note, on the AOLserver mail list there is effort to embed
Python and get Zope running on AOLserver. I think it would be great to
see Zope/Python being multi-thread, multi-processor able on a high
performance open source, multi-threaded webserver. It would be awesome
to have an embedded Python interpreter in AOLserver without a global
threadlock that worked with AOLserver's multi-threaded API running Zope.

On another side. A website I just learned about does a performance index
of many sites and gives a average amount of time to load pages. This
could put into perspective Zopes performance from the real world, from
your own website.

you need to put HTML comments at the beginning and end of your DTML
methods. These will be passed unchanged to the final page, and any
problems pointed out by your validator will be pinpointed.

The problem is a bit deeper than that. Even if a validator could be
convinced to ignore DTML, you would still have the problem of trying to
analyze an incomplete HTML document.

Message-ID: <000c01bf85fa$bfd07090$0201a8c0@iridium>

Hi,

This question may be very naive but is there any way to use Zope as a
mailing list manager?

The sort of thing I want to do is :

1. Check a mailbox for messages.
2. Grab any that are related to my Zope WebApplication
3. Process each message "request" depending on its content.
4. Send one or more email replies to one or more recipients (easy with what
is already in Zope).

This might allow me to create a simple list manager for instance or allow a
virtual mailbox for all my WebApp members.

I have not followed the discussions you're referring to, so this may be
old news to you, but one simple way to provide XML compliance without
screwing up the HTML is to require that the HTML -- or whatever you're
rendering -- must be properly UTF-8 encoded. This is probably the least
painful way of attaining XML compliance. 

Unfortunately, it *will* be painful unless you're also using an
XML-compliant editor. The low-level DTML source will end up looking a
bit like this:

  &lt;html&gt;
  &lt;head&gt;&lt;title&gt;<var name="title_or_id"/>&lt;/title&gt;
  &lt;/head&gt;
  [...]
  &lt;/html&gt;

The editor takes care of the en-/decoding of character entities.

An obvious alternative is to use XHTML and XML namespaces, which would
currently -- because clients aren't usually XHTML-aware -- incur
additional XHTML-to-HTML processing on the server side.

Just on a personal note: I _like_ the curtesy reply to my personal account.
I redirect mailinglists to their own folder. On a list like Zope, that is
very busy, I would very easily miss replies to my messages.

With a good filter (like I use), I get a personal reply into my In box, not

Subject: [Zope] setting a DTML method's namespace from a product method
Message-ID: <874sameir7.fsf@wiz.wiz>

I'm having some troubles with manipulating the namespace of DTML
methods that are called from methods of product instances.

Some questions:

- How do I provide a DTML method with a full acquisition namespace, as 
if it were called in DTML, when I call it from a product class method?

- Does a REQUEST.set(somevar, somevalue) operation add a variable to
the namespace, or does it re-initialize a new request? I can hardly
imagine the latter.

- Does the local scope of a class method in a product somehow
propagate itself to external DTML methods that are called from that
class method?

Context of my problem:

My product has the following class:

class NFGnav(
	OFS.SimpleItem.Item, 
	Persistent,
	Acquisition.Implicit,
	AccessControl.Role.RoleManager
	): 

which ultimately calls a DTML method:

	  return self.NFGnav_ActiveMapItem(REQUEST)

I can set arguments for the DTML method, no problem:
	  REQUEST.set('NFGnav_ItemTitle', object.title_or_id())
before calling the DTML method works just fine.

However, the DTML method seems to lose it's acquisition context in the 
process. That is, if I define an 'myimage' instance somewhere higher up in
the site hierarchy, I get KeyErrors if I try to call
	<dtml-var myimage>
from the DTML method.

Funny thing is, if I request the URL of the product instance with the
'myimage' appended, this seems to have no problem:
		  /mysite/somefolder/ProductInstance/myimage
returns the image, whereas
		/mysite/somefolder/ProductInstance/someMethod/myimage
gives a KeyError. So the aquisition context seems to be intact at the
product class level, but not at the product class method level. 

I took care to provide (PARENTS, REQUEST) parameters for every class
method invocation, by the way.

I'd appreciate any suggestions in tackling this problem. Is this
question more suited for the zope list or for the zope-dev list, by
the way?

Even simpler than buying new hardware, switch to a system like NetBSD or
FreeBSD that has supported large files for years and years :-)

I'm not sure if you considered this, but note that LD_LIBRARY_PATH needs
to point to *Python's* libraries, not Zopes.  It's not python that can't
find ExtensionClass.so, it's ExtensionClass.so that can't find the
standard Python library module.

Your message sort of implies that you were ensuring that
ExtensionClass.so was in the library path, but the problem (I think) is
that the Python libs are not in your path.

I could be wrong and this could be an entirely unrelated issue.  Can you
run python normally?  Import stuff like cPickle?

Welcome back, Jimmie. I enjoyed reading your analysis and agree with
the thrust of it.

One thing you express, and which seems to have ossified into the current
received wisdom, is that scalability will be improved  when some
mythical deep pockets consulting client pays to get it improved ; then
everyone else will benefit. The problem is with the leap of faith it
requires from the client.

I currently have several clients who are very interested in Zope.
Their web sites already receive megahits. They are willing to pay money
for consulting, but certainly won't bank their businesses on the chance
that a magic key to scalability is found. As a consequence, the
greatest commitment they will make is to install Zope on a Linux server
on a VPN and "see how it goes" in a toy setting.

Therefore, I can testify that right now, today, Zope is being hurt by
the lack of a story on scalability.

If economics or policy dictates that Zope requires an "Angel" to
bankroll scalability research, we all have to be prepared for a
scenario in which that Angel never appears. Personally, I don't like
taking such a passive approach.

Two clear impediments to Zope's wide acceptance have been frequently
discussed on this list -- documentation and performance.

The documentation "story" has travelled on an arc which might be
expressed like this:

* Zope is Open Source. The community should document.
* The community can't take on the deeper Zen issues
* Volunteers from the community are time constrained
* DC hires a technical writer
* The ZDP is formed
* ZDP suffers from the lack of time available to its volunteers
* DC commits Amos to attack the general documentation problem and to
evangelize documentation

Documentation currently seems headed on a good track. What have we
learned from this trajectory? We've all learned that the Zope experiment
is different from other Open Source projects. It *needs* the cooperation
of *both* the Zope community and Zope's authors "shooting at the same
basket" to solve this.

I believe scalability requires a similar coordinated attack and that it
can't wait to be bankrolled.

ZEO, although a bit of a black box to us at the moment, sounds, on
paper, like a logical and credible attack on one aspect of scalability
-- the "throw hardware at it" approach.

No doubt there are other hidden opportunities. What kinds of hidden
opportunities? Who knows; they're hidden. ;>) But can we bring them out
of hiding?

Some of them are simple applications of available compute science, yet
I don't see these codified or set down anywhere. Perhaps we should have
a single HOW-TO repository for techniques and metrics people have
discovered, or just happen to know, in the performance arena. This
would be a FAQ along the lines of "I want to build my Zope site for
best performance. What things should I do? What things should I avoid?"
God knows this question comes up often enough.

Then there's the design and makeup of the Zope software itself. Its
original design requirement probably didn't put scalability at the top
of the stack. Here, there are probably other areas where the user
community can't know enough about inner workings and overall design to
contribute effectively -- but which require attention and a commitment
from the folks at DC. I'll mention a couple of things that pop into my
head. These are simply conjectural -- dialog starters. I'll be happy to
be shown that I'm dead wrong about any of these conjectures.

Zope began as a brilliant notion, of Jim Fulton's devising. It began as
a fews lines of code and has evolved to include better than two
megabytes of code. DC has evolved from a company with one employee to a
company with maybe a dozen engineers contributing to the code
base and is looking to hire twenty more engineers.

Among this team of top notch talent, who takes ultimate responsibility
for evangelizing and improving performance? Who leads the effort at
code review, with an eye to marshalling refactoring efforts?

What would be an example? OK, Devil's Advocate: Here's one area of
concern I have, perhaps unfounded. Digital Creations utilizes Use Cases
as a tool for design, in the Ivor Jacobson tradition. Use Cases have
many proponents and some detractors. One detractor is Bertrand Meyer,
author of the classic _Object-Oriented Software Construction_. His beef
with the use of Use Cases is that it poses a fundamental risk: it
encourages a functional approach, based on processes (actions). He sees
this as the reverse of O-O decomposition, which focuses on data
abstraction. He believes it carries a risk of reverting, under the
heading of object-oriented development, to the traditional forms of
functional design, by considering what the system does, rather than
what it does it to. He believes that, due to this risk, Use Cases
should be confined to use as a validation tool, not a design tool, to
avoid closing interfaces prematurely.

So let's say that Use Cases is a useful tool, but one that has a subtle
built-in gotcha. What are the dangers? Naturally, one is negative
impact on code maintainability/reusability.

Another may arise due to the need to balance two competing technical
concerns: the desire to encapsulate abstractions, and the need to make
certain abstractions visible to other modules. With regard to the
dynamics of subprogram calls, the placement of declarations within
modules can greatly affect the locality of reference and thus the
paging behavior of a virtual memory system. Poor locality happens when
subprogram calls occur across segments and lead to cache misses and
page thrashing, which can ultimately slow down the whole system.

Is Zope prey to this? I don't have a clue. Does anyone? Like I say, I'd
be happy to be shown that this concern is unfounded. But this is the
sort of creeping problem which can enter into a growing code base like
Zope's, as it is worked on by numerous people, each devoted on one
module or interface. Combatting such problems probably requires having
someone (someone blessed with both Jim Fulton's dedication to O-O
principles and an unbending zealotry for absolute performance)
committed to periodically flying above the code at a sufficient
distance to see such patterns and making bombing runs against the
target problems. As busy as everyone at DC is, I'm not certain that
anyone is doing that at the moment.

Thanks for the replies!

I did get it to work.  Here is what i did:





I created a new python method inside my primary class:

    def is_local_name(self, name):
        """ returns true with ID if name is a local user
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].validated, rlist)
        rlist = filter(lambda x,p=self : p.data[x].meta_type ==
'SRPersonPost', rlist)
        rlist = filter(lambda x,p=self : p.data[x].name, rlist)
        rlist = filter(lambda x,p=self,s=thisdjname : p.data[x].name == s,
rlist)
        return rlist






then called it using this dtml:

<dtml-if namelist>
  <dtml-in namelist>
   <dtml-let thisname=sequence-item>
    <dtml-if "is_local_name(_['sequence-item'])">
     <dtml-in "is_local_name(_['sequence-item'])">

I checked the WU IMAP mailing list, and found the following:

  http://www.washington.edu/imap/listarch/msg06947.html

In short, Mark Crispin (the author of WU IMAP) strongly recommends avoiding the
"*" wildcard altogether, using rather "%".  In this case, the '\NoSelect' flag
indicates (I think) that the item is a directory, and could be drilled into; 
or  perhaps the '\NoInferiors' says "this is a leaf -- don't descend" (my
ignorance of the IMAP protocol is showing).

I guess the idea here is to avoid using LIST once, but to do it "on demand" as
the user drills down the tree.  Mark also recommends using "LSUB" to pick up
"subscribed" mail folders.

Hope this helps!

Tres.

StructuredText expects list elements to be separate "paragraphs", where the
paragraph separator is an empty line.  Also, the indentation determines whether
the line before the list elements is treated as a header or as a paragraph.
Try::

 This is my document.
 
 - bullet1

 - Bullet2

which makes the preceding line a paragraph, or::

 Header Goes Here!
 
   - bullet1

   - Bullet2

Message-ID: <38C22166.EFC36537@aHIT.de>

Many thanks to Michael the author of TTImage
for pubishing your Product at zope.org.
You did a great job !

In order to create TTImage instances within DTML-Documents I made
some changes on TTImageClass_add because I got errors due to
empty BasicProps and DestinationURL.
Would be nice if you could include it in your next release.

I´m new with Python and especially with PIL so at the moment it´s 
not so easy for me to fix some further problems with the background
color.
When I set the backgroung color to 0xffffff the background color of the 
result is 0xfcfcfc ... seems to be an color palette problem ...   

Also I was wondering if it is possible to set the background to
transparent ?

I look forward to hearing your thoughts on my changes :-)

Andreas Heckel

Hi Matt!

I ran into this same problem. I finally traced it to a problem in the IMAP and
SMTP server options set in the setup screen. It seems to work best when these
are explicitly set to localhost and localhost. I'm not sure why but that's how
I got it to stop giving me that particular error. Unfortunately it will require
removing the current WorldPilot object and replacing it with a new one since
those parameters are not visible on the parameter tab of the object.

Good Luck!

Thanks, however I think they only work on date objects.

There is a DateTime() function to create date objects mentioned in the
DTML guide, but it doesn't seem to be documented.

Nevertheless, I would be interested in why atoi does not work for me.

Okay, it's simple enough - 

<dtml-call "REQUEST.set('mydate',_.DateTime('2000/12/31'))">

creates the date object I need to then reformat it.

Thanks,

It was never my intention to imply that throwing $$$dollars at DC was
required to improve scalability. What I said was based on perception of
such requirement. I'll admit "currently" Zope does not scale as well or
as elegantly as I would like. A statement I was making was that "if" I
(or anyone) "believed" that scalability == $$$dollars, I would rather
give to DC than Oracle. I believe Larry is doing all right on his own.
:)

I find Oracle pricing obscene. For the kind of $dollars it would take to
license Oracle I would rather see what DC could do with the additional
employees on beefing up Zope/ZODBs concurrency/scalabilities. There is a
thread on the WebDB forum about a group of people talking about putting
together a co-op to buy an Oracle license based on Oracles "unit"
pricing scheme for a moderately powered single processor Intel machine
it was going to run about $20,000. You would have to renegotiate if your
site got busy and you added a processor. Yuck!

I believe Zope's scalability issues will be solved over time regardless
of external $dollars. I believe more $dollars could speed up the
process, however it will still take some time. Currently ZEO is an
option but I don't know how well understood it is by the community.

Scalability Now can still be a sticky wicket.

Future things on Zope's side:
1. Moore's law.
2. Advances in Python and it's performance.
   a. Python becomes fully multi-threaded, multi-processorable.
   b. Stackless Python gets adopted and performance improves.
   c. Viper 
3. Advances in Zope, it's architecture and performance.
   a. Sam Rushing works miracles on Medusa/Zserver using Stackless
Python and Continuations.
   b. Zope does process pooling with each process on a different
processor. ZEO?
   c. ZODB does multiple data.fs's based on user design based on url
path directories
        allowing different Zope processes on different processors to
handle their respective dir.

It would be nice if some C/Python programming guru/genius would solve
Python's global threadlock issues where Python would scale on
multiprocessor machines. This would potentially render scalability a
moot point. The geniuses at AOLserver rewrote the threading of the
built-in Tcl interpreter so that it would be multi-threaded and work
properly with their nice multi-threaded webserver. Tcl's standard
threading I don't think (I could be wrong) is as nice as Python's.

If I had Oracle kind of money to throw around I would like to see
Python's thread issue resolved where Python becomes fully
multi-processorable. That would transparently scale Zope and benefit
other Python user's as well. It would enable Python/Zope to embed well
and play nice in multi-threaded webservers like AOLserver and others.
IIRC Apache 2.0 will be multi-threaded. If Python scaled on
multi-processors even a little guy could put together a dual-celery
machine a serve a nice site.

I agree wholeheartedly with you that there should be a concerted
coordinated effort between DC and the community to improve scalability
by allowing people to throw hardware at it. That was the primary issue
causing me to wander the websphere looking at options. I've learned some
things in the search, but I always looked back at Zope, even tho' my
wife liked Enhydra's logo, she thinks the otter is cute. Zope's current
logo is much nicer than the Purple and Gold. :)

If ZEO currently scales well, then DC needs some testimonials on their
website.

There definitely needs to be some documentation best ways to...
As you said, there is a consistent recurring thread of is ZServer alone
or ZServer behind Apache better.
Should I use a RDBMS or ZODB.
...

Some of us have no legacy issues. From scratch what's the best way to
design...

I agree the solving of Performance/Scalability and Documentation issues
would definitely help convert lookers into believers.

I am currently working my way through the docs and plan on helping
there.

While I was wandering, in my heart Zope was the project I wanted to see
succeed. I decided to put my mind where my heart was.  Possibly someday
some of my money too. :)

Some of your other concerns I can't address. However, one of the nice
things about Zope is that it is written in Python. Python imminently
supports playing and algorithm improvement. :)

Oops, spoke too soon.  Spent the last few hours trying to suss this out
without any progress :-(

I have a variable called START returned by a sqlquery

<dtml-call "REQUEST.set('startdate',START)">
start is <dtml-var startdate>

and that's okay

<dtml-call "REQUEST.set('month',_.DateTime(startdate).aMonth">

That, and variations of the same, dies with

Error Type: TypeError
Error Value: __div__ nor __rdiv__ defined for these operands

Why is that these simple little things are so difficult in Zope?

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

FreeBSD on intel architecture doesn't have the large file limit of Linux.

Not exactly true.  The *BSD's, like most of the rest of the world,
implement the basic POSIX file APIs which use a signed 32bit long
for file offsets in the base ABIs.  Ergo. if you are using the
equivalent of C's fseek(...SEEK_SET) (from beginning of file), you
are explicitly limited in the maximum size files you can process.

There are multiple hacked ways to work around this, one of which is
to allow offsets from SEEK_CUR to page-flip out into longer files
(just never use a SEEK_SET), or to implement another, parallel ABI
which takes a 63/64bit offset value.  Neither of which however helps 
the poor application which merely expected standards compliant
behaviour from its host and therefore didn't play by the local
"special rules",

Not completely correct.

man lseek... it doesn't work on file streams (fopen ), it works on 
file descriptors like poll and select,  and, it works on very very large files.

lseek is a POSIX interface, and has been a part of linux since at least 1995.
Indeed the BSD and Linux manpages are basically identical including this as 
a bug:

No, a Redirect is a client side thing. The response will tell your browser

You have to start up your Zope install in non-debug mode. By default, it is
started with the -D flag (see you start script). Remove that flag, and all
your tracebacks will be demoted to HTML comments.

Yup. Take a look at REQUEST.environ['HTTP_USER_AGENT'], which is also
accessible as:

  REQUEST.HTTP_USER_AGENT
  REQUEST['HTTP_USER_AGENT']

and in DTML also as

  HTTP_USER_AGENT

On Zope 2.1.4 (Win 32):
- I get "1900/02/28" when entering "2/28/00".
- I get "2000/02/28" when entering  "2/28/2000".

No errors. (I tested this on the Properties tab of a DTML Document).

The issue you report seems to be corrected in the last Zope subversion.


Cheers.

- To get the modify time for a file, use this code in a DTML document or 
method:

<dtml-with yourFileName>
   <dtml-var bobobase_modification_time>

or
<dtml-var "yourFileName.bobobase_modification_time()">

   How do I use bobobase_modification_time on a file object ? 
                      
   To get the modify time for a file, use this code in a DTML
   document or method : 

   <dtml-with yourFileName>                                          
   <dtml-var bobobase_modification_time>

   or 

   <dtml-var "yourFileName.bobobase_modification_time()">

   If your filename includes a dot, use instead: 

   <dtml-with "_['yourFileName.gif']">
     <dtml-var bobobase_modification_time>
   </dtml-with>

   or

Message-ID: <14530.26613.662250.268116@loki.1012internet.at>

I want to do the following tasks

A user enters a list of products. Such a list is equivalent to
an order. Then i want the user to enter some things for each
product. I don't want to implement DTML pages for each
combination of products and i want to present one entry
screen for each order.

I tried the following approach:
I created a Folder named 'Products'. In this folder i
created subfolders named after the prducts code number,
e.g. `4007', `4008'., ....

In each of these folders i defined a DTML Method `New' which
hholds the DTML code to create an input form fr this product. My
plan is also to create methods named 'Display', 'Edit', .... so
i can render the objects in different ways.

In anotehr page i want to do something like:

<dtml-in products>
   <dtml-var "URL1 + '/Products/' + _['sequence-item'] + '/New'">
</dtml-in>


but this doesn't work. Nothing is displayed. I also tries
<dtml-var expr="...."> and <dtml-call "..."> (the last one
was pure desperation).


So what's the correct method for implementig such a system?

[many good points cut away]

| I don't like Dynamo, but I acknowledge its technical edge on Zope
| (and other solutions) in several areas, such as clustering,
| reporting, personalization services, e-commerce services, stability,
| and raw speed.

Not that I have very much to base a comparison on, but I regard Zope
as both stable and fairly speedy.  I think I can guess in what regards
an alternative could be faster, but I'd really appreciate to learn
where Zope lacks in stability.  Can you provide any references?

I don't quite grok what "the situation" is referring to, but I think
you're wrong here, or at least mistaken regarding the meaning of
"proprietary".  Proprietary, according to Merriam-Webster, means this:

[cut from Merriam-Webster]
Function: adjective
Etymology: Late Latin proprietarius, from Latin proprietas property --
           more at PROPERTY
Date: 1589

    <a proprietary process>
3 : privately owned and managed and run as a profit-making
    organization  <a proprietary clinic> 
[/]

| factor is too low; 
[...]
| We tech people know better, we know a shiny surface tells us nothing
| about the engine underneath, but we tech people are not holding the
| crucial component -- those big brown bags of money.

I'm not sure if I agree it's a problem, then, that Zope lacks in the
big-department. :-)

| [under Zope's surface] lies a powerful engine with scalability
| problems.

What part of Zope's engine are you referring to here?  Do you mean
Python in general, are some specific part?  Like ZODB?

| So far the only way to scale properly with Zope is a combination of
| a load-balancing clustering system (eg., TurboLinux' TurboCluster
| Server, which I can personally vouch for -- brilliant stuff -- or
| Linux Virtual Server) with Digital Creations' ZEO, of which I've
| only read about.

I actually thought of ZEO as a very nice way to scale Zope.

| There are Zope sites out there that are suffering scalability
| problems (I won't mention specifics, other than that the project I'm

It would be very much appreciated if you could share some specifics.

[...]

I second that.

[...]

| -- in whatever form -- then support for
| performance/monitoring/management APIs such as SNMP, PCP, WBEM, and
| to a lesser extent PDH, aren't difficult to isolate into add-on

You are right about that, and I think that's a better way to provide
such support, rather then building specific support for any of them
into Zope.

2. what's wrong if there is no table-update after

Ty, I considered this, and looked into Net/Free/OpenBSD, but I was under
the impression that using Zope on any of them was a bit 'o the pain in
the ass.  Plus, I couldn't find any info on other possible hardware
related issues, like using >32GB IDE drives, which even my BIOS refuses
to talk to.

(if someone could give me the slightest hint as to *why* things would
crap out at 4GB, I'd be greatful.)

A more zopish would be: define your 'New', 'Display' and 'Edit' methods
in the Products folder and use properties in the subfolders for the
different rendering. For example:

give each subfolder a property 'Description', and a property 'Price', in
your Display method put something like:

Description: <dtml-var Description><br>
Costs: <dtml-var Price>

So, with an url http://yourhost/Products/4007/Display

Display is rendered in the context of the object '4007' and its
properties will be used.

This is a bit unclear. Where do you call it (note that Zope doesn't know
'pages', it only knows objects, which define what's going on) and where
does the 'products' come from? I assume you want something like this:

<dtml-in "objectValues(['Folder'])"> 
   <dtml-var absolute_url>/New <dtml-var title_or_id><br>
</dtml-in>

objectValues(['Folder']) gives a list of all (sub)folders of the current
object. Note, that if you put this into a DTML Document, the list will
be empty, because a DTML Document is an object by itself, which has no
folders associated with. You'll need in an DTML Document a <dtml-with
"PARENTS[0]">, this will include the namespace of the folder object,
where the DTML Document is called from.

For each found item <dtml-var absolute_url> displays the absolute url

Generally, this sounds like a typical ZClass task. Have a look into the
ZClass tutorial and into the example products (there is one called the
boring product on Zope.org) for more informations.

Is START being returned as a string, or as a DateTime from your query? If
it's being returned as a string, you need:

  <dtml-call "REQUEST.set('startdate', _.DateTime(START))">

aMonth() is a method, not an attribute. You need to _call_ it, i.e.:

  <dtml-call "REQUEST.set('month', _.DateTime(startdate).aMonth())">

or, if startdate is already a DateTime:

  <dtml-call "REQUEST.set('month', startdate.aMonth())">

Another way of doing this, however, is something like the following:

  <dtml-call "REQUEST.set('mydate', _.DateTime('2000/12/31'))">
  <dtml-var mydate fmt=dd>-<dtml-var mydate fmt=aMonth>-<dtml-var mydate
fmt=year>

Voila.

The above does not seem too difficult to me. You made a few simple
mistakes, that's all.

I forgot that you can also use C-style formatting, which reads much better
in this case:

  <dtml-var mydate fmt="%d-%b-%Y">

Try (untested):

  <dtml-in expr="Products.objectValues()">
    <dtml-var expr="_['sequence-item'].New(_.None, _)">
  </dtml-in>

I would investigate ZClasses. It seems to me like you could end up with a
"Product" ZClass (though I might call it something else to avoid confusion
with Zope Products), which contains your New, Edit, and Display methods.

Depending on how much each Product differs, you might have a
WidgetProduct, ThingamabobProduct, DoohickeyProduct, etc. Or, maybe you
can just get away with Product. I'd have to know more specifics to get
into detail.

I'm a relative beginner to Zope, so I'm not sure what I'm talking
about <grin>, but it seems to me from my limited experience that
you can't call out an object using a URL in a dtml-var.  Instead
you need an object reference.  So try something along these
lines (this is untested because I'm in the middle of my own
debugging mess):

<dtml-in products>
  <dtml-var "Products.get_item(_['sequence-item'],0).New"
</dtml-in>

I'm sure the above is not right from a Zope standpoint, and
the Python is probably wrong too, but maybe it will send you in
in the right direction.  What I'm aming for with that psuedo code
is to get the property of Products whose name is in sequence-item,
without rendering it (that's the ',0' bit), and to pick up
*its* 'New' property and render that.  Maybe a real Zope expert
can correct my code.

Or more likely, as others have suggested, using a ZClass is the
right direction anyway, which would avoid the whole syntax issue
<grin>.

It works as written

Subject: [Zope] More search engine woes
Message-ID: <E12RiXK-0007iL-00@ethereal>

I'm not sure if this is a PTK-specific issue, but I'm starting to
believe that it isn't. So I thought I'd post here with my problem and
see if someone could possibly point me in the right direction. I also
unsubscribed from the list recently, so please CC me with any replies.

I'm using Zope on a student organization website which I am
developing. Ideally I'd like for this to be an extremely popular
community-driven site, so a working search engine would be a
necessity. Additionally, I'd like to exclude unapproved items from
searches so that only moderated content is placed in the queue of news
items and ad banners which are being indexed. I'm also writing
site-specific documentation which is intended to guide members through
the process of creating news items, ad banners, etc., and I'd very
much like to have this content indexed as well.

Today I noticed that my search engine failed to produce any
results. Searching for the letter 'e' didn't even reveal anything,
which is unusual since E is the most common letter in the English
language AFAIK. So I tried digging into the ZCatalog documentation,
and poking around in the interface has confused me.

I created a help folder, and added an advertising document which
briefly explains how to create news items and such. Yet, I can't seem
to get this item to appear in the ZCatalog. In fact, the only item
which does appear is /Members/nolan, my PTK account page. Clicking on
the "find" tab and checking the "all items" checkbox seems to imply
that all items of every type on my site will be cataloged, but doing
this always results in only one page being listed in the catalog. Is
there some reason why the contents of help/ aren't being listed?

Thanks a bunch. If I can provide any additional information then I
will be glad to do so.

Ran into this one myself - the solution is to remove the DocumentRoot
directive, then just use the SetHandler and similar tags in the body
of the config file, though you can put them in a location container if 
you like.

Subject: [Zope] Setting attribute from DTML method in ZClass
Message-ID: <20000305223451.A15162@mimar.demon.nl>

Hi,

I've created a ZClass with a method 'force_update'. When a user is viewing
an object, there is a formbutton which they can press and force_update is
then called. So far it works. What I want my force_update to do, is that
it should set the needs_check (type boolean) in the object to true.
With <dtml-if needs_check> I print different things depending on whether
the object needs a check. From the Property sheet I can change the
settings. 

So, how do I put something like this().needs_check = 1 in a dtml-method?

Greetings,
    Chris Niekel

Message-ID: <010301bf86f3$d507db20$c3f28ec6@hikari.anu.edu.au>

I have a ZClass (Shot) which is nested beneath
a container ZClass (Storyboard).  I.e., an
instance of Storyboard might be:

Scene1 (Storyboard)
 - shot1 (Shot)
 - shot2 (Shot)
 - shot3 (Shot) ...

For reasons that I cannot discern, copying and pasting 
instances of Shot does not work.  I can copy them, but 
pasting creates a broken object:

  "This object is broken because the unknown product that 
   created it is no longer installed or is installed 
   incorrectly."

I suspect the copy has in fact worked because the title
in brackets is that of the source object.  This is an 
isolated problem on my site.  All other nested Zclasses 
work fine but I cannot pin down the difference.  This is 
Zope 2.1.4.

Has anyone else encountered this problem?

Darran.

Subject: [Zope] Simple Z Search Question - lost something while renaming
Message-ID: <000601bf86f4$06c5c5f0$0100a8c0@pinol1.sfba.home.com>

I'm trying to determine what might have failed in a Z Search generated set
of objects.

I used the Z Search wizard to create the search interface and tabular
report. They ran fine. I then renamed the data source (odbc) and both the Z
Search generated objects. I made sure that the input form reflected the new
report name. Now the input form will come up but when attempting to search I
get a "Object Doesn't Exist" type error.

I've also recreated the tabular report and it's input form with the Z Search
interface, and of course they work. I think the problem is with the report
as the original input form will sucessfully populate the recreated report.
What's interesting is that a compare of the text in the original vs the new
Z Search created report object show that they contain identical text.

I've also used Z Search to creat a similar "record" format pair of objects
that seem to endure any number of renamings, which is puzzling too.

I think that there are some variables hidden away, properties, whatever,
that I can't get to. This is probably pretty transparent to everyone, but
it's a bit of a stumper for me. In general this is a useful experiment as
it's obviously very important to know what effect name changes will have.
The docs state something to the effect that it's not too wise to change
names, but I've also seen that some name changes are propagated. So it would
be great to know what the pattern is. Maybe it's as simple as "rename at
your own risk".

hi all,

i installed fastcgi on my server and added -appconntimeout 0 (as suggested by
ppetru).  tried both unix and tcp socket.  however, i can't get 100%
availability.  there still exist connection failed (connection refused) errors
and incomplete headers 0 errors.

my config
rhl 6.1, pIII 500M, 776M RAM, oct6 fastcgi snapshot, FCGIServer.py from cvs ver
1.7, zope 2.1.3

i glanced at FCGIServer.py.  there were references of max connection (10) and
max request(50).  will this have any bearing on the connection refused error?

do i need to d/l other files instead of only FCGIServer.py?
i am also considering mod_pcgi2.  can anybody with fastcgi and mod_pcgi2
experience enlighten me?

This how-to will give you all the details:
http://www.zope.org/Members/lstaffor/zProperties

The short of it is that you need to call manage_changeProperties for the
propertysheet in question (which is actually what you need to do in Python
as well).

<dtml-call
"propertysheets.YourPropSheet.manage_changeProperties({'needs_check' : 1})">

It is very stable, indeed, so I take that back. ;-)

There are cases where I have been forced to kill Zope processes that
have falled into some sort of coma, but I've written these off as
growing pains in an evolving product. ;-) To date, Zope's stability
problems seem to have been mostly related to fragile database drivers.

I was really thinking of something else, and should have used another
phrase -- something like "high availability". Again, I have only read
the marketing material on ZEO, the product that supposedly provides such
features (load balancing, replication). Assuming ZEO works, strike that
from my list.

What I've observed is that I'm running Zope on Linux and accessing it from
a browser on a Windows box. I can create empty File objects and file
objects containing _text_ files without a problem, but as soon as I try and
include or upload an _.exe_ file it barfs with the commit_sub error.
I'm wondering whether there's something occuring inside the .exe file
that's playing up with the storage mechanism, maybe some kind of terminator
or something...

(I tried uploading files from Solaris and uploaded text files from there
fine, so I was thinking it was a windows problem, but upon trying them text
files worked under windows as well. It definitely seems to be an exe
problem instead.)

I mean proprietary as being controlled by a private party -- owned, in a
very liberal sense -- as opposed to being standarized. XML is not
proprietary. DTML and Java are.

I'm not as knowledge about IP laws as I would like to be, so I can't
really defend my use of this word or whether DTML is an intellectual
property of Digital Creations. Perhaps somebody else more suited to the
task could clarify.

If the suits in managements (assuming you work in such a place) tell you
to go learn Dynamo because that's what they want to use, wouldn't you
say it's a problem?

I definitely believe that Python is Zope's largest problem right now.
It's also, from a technical point of view, one of it's biggest assets --
Zope is becoming the killer application of Python, and might eventually
become the driving force to evolve Python, which is, I believe,
suffering from draught into the contributor department. Skilled
developers aren't flocking to Python to make it faster. Not right now,
anyway.

My hope is that Zope will change this, because Python has possibly one
of the slowest interpreters on earth. Python zealots -- and there is
such a beast -- will tell you that Python's performance is less of a
matter because what you sacrifice in speed you gain in power, ie.
computational expressiveness through a high-level, dynamic language.

For an example of a good, Python-like, dynamic language that is also
very fast, take a look at Dylan. In current implementations, Dylan is
not interpreted but rather compiled to native code, but in theory there
is nothing stopping anyone from writing a highly efficient Dylan
interpreter. Dylan's magic comes from its use of type hints, a system
which I had recognized as likely pivotal to improving Python's
interpreter long before I knew of Dylan. In Dylan, specifying a
variable's type is optional. When omitted, the Dylan compiler will
usually be able to infer the type from what you do with the variable
(ie., it sees you're assigning an integer to it; hence it can assume
that, for at least a stretch of execution, the variable remains an
integer). When you explicitly declare a variable's type, Dylan applies
the necessary code optimizations (such as using tight integer maths or
string copying) as well as static type checking. In Python, variables
can hold virtually anything, and this incurs a huge amount of checks.

Just imagine -- while Zope is running, thousands and thousands of the
same little checks are performed continuously, over and over again,
amounting to no uncertain overhead.

Python's biggest overhead comes from its dynamism -- the dynamic typing,
as explained, combined the object allocation system: most things is an
object, so a lot of objects are constantly spawned and torn down, often
in rapid succession because the compiler/interpreter can make few hard
analyses of when stuff is needed. Python also has a high function-call
overhead.

I agree.

No. Ask around, do some research. Ask Digital Creations -- they probably
know of a few, although I'm guessing that they might feel it would hurt
their reputation to tell. Many companies using Zope might not want to
tell you because it would hurt their position, especially if they're
public companies.

Here's one specific case that I'm personally struggling with. I have a
page that returns a large number of dynamic database results in a
relatively simple table. The results are first munged by a small Python
script. This stuff is slow. Internally, as far as I can determine
(through shallow study of the database code), Zope allocates a row
object for every row you access -- even if the row has been returned
earlier on. Zope has a 1-row cache for cases when you repeatedly ask for
the same row in succession. Zope also has a row cache that is useful for
static result sets. Yet, for dynamic result sets, the processing
overhead is huge. The overhead isn't so higher than any other overhead
in other areas in Zope, but it's especially painful here, because it
affects the generation time of a single page, whereas other kinds of
overhead are more evenly distributed across multiple pages and multiple
users.

Exactly. However, the necessary counters must be built into Zope at some
point, and exposed through a common (XML? Python/XML-RPC?) API. Then we
could attach publishers for SNMP, HTML, XML, whatever.

Which reminds me. Does Zope have a mechanism for extending the
Control_Panel namespace other than through the Product sub-folder? I'm
too lazy to check, and I don't remember if this was ever discussed.

I need record level locking in a database, and I need it quickly, without having

recommend.  Does Postgres allow record level locking?  I am on a linux platform,
and refuse to use any MS products, so don't go there.  Additionally, I need to
be able to easily export database content as both SQL statements and in some
sort of delimited text file format.  I can do the latter with Zope, of course,
but it is fairly slow and expensive.  MySQL does all of that nicely, but doesn't
have record level locking.  Please respond to me as well as the list.

Subject: [Zope] Zope Documentation Project (ZDP) Announcement
Message-ID: <38C31F68.123691B3@berg.net>

Dear Zopistas,


The Zope Documentation Project is pleased to announce the availability of
the new zdp.zope.org website, which aims to give the Zope community
an additional place for sharing knowledge, and for working together
on providing good Zope documentation. The new ZDP homepage already contains
many useful resources for the Zope community, which for the most part
complement the already existing types of documentation available on zope.org. 

We sincerely hope that Digital Creations will play an active role in
the Zope Documentation Project and help merging the existing Zope documentation
with the documentation provided via ZDP. To see what Digital Creation's Plans
for Zope Documentation are, have a look at:
http://www.zope.org/Members/Amos/Documentation/Plan

When we built the new ZDP site, great emphasis was placed on providing
ways to easily get aware of what is new on the site and to quickly get
an overview of what pieces of documentation need Maintainers, Writers,
Commenters and Reviewers. Thereby contributors are directed to the
documents and projects that need help. Everyone can contribute according
to their interest and level of experience.

We invite you to join the ZDP and to help building up a great
knowledge base on Zope. This also includes helping to customize and 
extend the ZDP-Tools, which is the software with which the ZDP site
was built and on which it runs. The ZDP-Tools are being developed 
on-site, and are completely written in DTML to allow for rapid 
through-the-web programming. Questions on the ZDP tools can either 
be directed to the ZDP mailing list or to me, as I am the ZDP-Tools
maintainer (Maik Röder, roeder@berg.net).

The most important sub-projects of the Zope Documentation Project are:

1. ZBook

   In this project, we are collaboratively writing a book about Zope.
   There are already many chapters, most of which are still drafts.
   We need feedback on these drafts, so maybe you can give some 
   comments directly on the drafts, or discuss them on the ZDP mailing
   list or directly with the author. The ZBook project is maintained 
   by Tom Deprez (tom.deprez@uz.kuleuven.ac.be). 

2. ZFAQ

   This project tries to answer the frequently asked questions on Zope.
   The project is in need of additional contributors, so if you
   have a  question on Zope, or an answer to share, then you are
   welcome to add it to the ZFAQ. If you want to help moving the old
   Zope FAQ  to the new one, then just contact Kamon Ayeva
   (kamon.ayeva@bureauveritas.com), the maintainer of the ZFAQ project.

3. ZSnippets

   Snippets are short pieces of DTML or Python code which come with a
   description of their purpose and how they work. This project is
   maintained by Rik Hoekstra (rik.hoekstra@inghist.nl), who will get
   an automatic email notification when you add a Snippet, so you are
   invited to help flooding his inbox ;-)

To become a ZDP member, write an email to the ZDP mailing list (zdp@zope.org),
and we will create an account for you. For the time being, this will give
you Manager rights on zdp.zope.org. Once we use a tool like the forthcoming
PTK Login Manager for automatically adding new members, we will have to
give more restricted access rights.

Thanks go out to Digital Creations for sponsoring the ZDP server at Codeit
Computing (http://www.codeit.com), a Zope Hosting Provider which is
kindly giving the ZDP project commercial support for an Advanced Zope
Hosting Server !

The ZDP site has not been tested under heavy load, so just in case 
you should experience down times, please report to the ZDP mailing list
at zdp@zope.org, and come back later. If you should not be able to 
reach this site under the name zdp.zope.org, try using the IP address
209.185.210.24 in the meantime.


So, you are invited to visit us at:

http://zdp.zope.org


Best Regards,

Maik Röder

Subject: [Zope] AS400, DB2 and Zope
Message-ID: <20000306032022.4041.qmail@www.eventera.com>

I am putting together a proposal for a steel, cooper and plastics
manufacturer based out of Germany, but with a large IT shop in 
Detroit. They are looking at Uniface Web Application Server, from 
Compuware, to do their web work. Although they approached me for 
my Uniface expertise, they seem open minded toward Zope. This is
their first experience building an application on the internet. 

Thier data is stored in a DB2 database on an AS400. While I have
used DB2, that has only been on MVS (don't the call it OS/390 now?,
am I dating myself?), and I was never the DBA. They seem to be
open minded about the operating system for deploying the web
application server, but I suspect that they will want to use
Solaris. I gues I am nervous because I don't know what I need
to know, and I don't have a AS400 laying around to play with.

Is ODBC an option for talking to DB2 on an AS400 from a Solaris 
box running Zope? How about from a linux box running Zope? Has
anyone heard the news on the OCI-based driver that DC promised
"real soon now" at the IPC8? Does anyone have that working?

I am going to pitch Zope and this project proposal on March 17.
There is a lot of money on the line, I appreciate any assitance and
my memory is long. If appropriate, please resond to me in private.

Greetings,


Look, I don't want to start any holy wars, just to get a head count, more or

Until now, I've been using Netscape, whilst desperately searching for some
replacement that didn't haemorhage memory.  I think I've even managed to narrow
down which part of NS is losing the memory (it's the edit box, which is why it
seems to happen quicker when working with ZOPE).

However, in my searches I've yet to find ANYTHING under Linux that comes close
to the functionality of NS.

As I said... I don't want advocacy here, simply name and version, and perhaps
a quick rundown of the reason(s) you chose it over others.

I am on windows and use IE 5.  However, when NS 6 (mozilla) comes out I am

Yep. In fact it goes quite a bit further:

It uses a BSD license so it's even more libre/lucre free than MySQL.

Er... do you mean ' I need to be able to easily export database

Or transactions, or constraits beyond NOT NULL and UNIQUE, or triggers 
or rules, or arrays or a dozen other things you'll wonder how you ever 
did without when you where using MySQL :-)

I'm running pretty much the same thing except for Zope 2.1.4.  I haven't had
any of the problems you describe.  I don't know if FastCGI changed from
2.1.3 or not, and I've only been using tcp socket.  I know this doesn't
really help solve your problem, but it does indicate that your setup
"should" work.

Subject: [Zope] beginner's question: references
Message-ID: <38C34B36.596AF966@primenet.com>

This is such a stupid question, but I can't seem to figure it out from
the docs.  How do I make an object in Zope reference another object?  I
don't mean containing like a folder, I mean one object referencing
another in a different part of the hierarchy.  For example, if I make a
class to represent movies, and another to represent theaters and I want
the movies to reference the theaters they're playing at and vice versa. 
How does Zope handle this?

Please try to frame an answer in the context of ZClasses, since that's
what I'm using.  (Or tell me if ZClasses can't do this yet.)

Thanks,
Perrin

Hi,

Problem:
    I have two web servers on one machine.  The first uses the standard
    port (80) the second (Zserver) uses port 8080.  How can I point
    to a page on the first server from the second?

Given:
    hostname:  monica.usc.edu

I've tried:  href="//monica.usc.edu:80/...

Results:
    * The page delivered to the browser has the site name including
      the ":80" stripped off.
    * Any foreign site name is NOT stripped off.

Well, you see... here's my problem.  I am using NS 4.7 on Linux.  And it chews
up memory like it's going out of style.  If I don't keep an eye on it, I wind
up in a swap-frenzy, and having to wait up to 5 minutes for response to any
keystroke (always the "KILL THE DAMN APP" keystroke :)

As for IE, i've had no 'back' problems with it when i do work from home (that

Help,

perhaps somebody from DC can help me swiftly?

Is it possible to use your own manage_afterAdd method in a ZClass which is
a descendant of CatalogAware Class? If so, how can you get this done?

Does there exist something like 'inherited manage_afterAdd', like in other
Object languages (eg Delphi?) : eg:

def manage_afterAdd ....
  <blablabla my stuff blabla>
  inherited (and does now performs the method from the parent class)


this doesn't seem to work :

def manage_afterAdd ...
  <my stuff>
  catalogAware.manage_afterAdd ... 

Help! Thanks in advance!

Tom.

Subject: [Zope] A zope fear...
Message-ID: <20000306033837.A12534@devware.com>

Several times I have heard folks mention a fear of "not being able to
get my files OUT of zope once they are in there." And usually the
answer is "Well just back up your Data.fs file and don't worry about
it."  I think perhaps this answer doesn't actually address the root
concern.  I think the root concern is one that I am actually coming up
against right now in debates about using Zope for a project.  That is,
if I stick with scripting languages or other traditional languages, if
I need to, I can always fall back on text processing tools to make
large global changes to my projects.  How can I do this with zope?
Many of us programmers are taught to learn to manipulate text like
magic.  Zope seems to take that power away from us.

So, the real heart of my question here is: I just spent 3 months
building a web site using Zope.  Suddenly, we decide to change our
database schema, and I now have to go through and change all 400 of my
SQL methods in zope.  How can I automate this process?  How can I do
this just like a good-ole multi file search and replace?

Answers that don't count are: Use the find mechanism built into
zope. - It's not powerful enough for this.

Another: Your design shouldn't have relied on something that would
change. - Well, it happens, now how do I fix it?

A secondary question here is, what about "software configuration
management" and zope?  What if I need to return to an exact version of
my web site for testing a certain bug that's now cropped up at a
customer site.  What's the easiest way to automate keeping old
versions around without having to roll back my current changes.  That
is, without using the built in versioning?  (Sorry, CVS *is* more
powerful in some cases)

Message-ID: <Pine.GS4.4.21.0003051530570.6405-100000@jeeves.stud.ntnu.no>

Zopistas,

I have a small problem here regarding uploading of files. We're setting up
a site where people can upload their MP3 files. We've tested everything on
our site, and everything seemed to work fine - until people started
uploading with modems.

They get timeouts, server not found etc. after around 5 minutes of
uploading. First we thought that it might be because of our proxy setup
with apache or - less likely - the external python method that handles
the file, but when I dug out my old 14.4Kbps modem and tried uploading
a 4MB file directly into Zope at port 9090, I got the same errors.

Is there any kind of timeout settings in the ZServer I can tweak?
Or is there something else going on?

Please help! This is very frustrating, as 90% of our users are modem
users...

Thanks in advance,


Alexander Limi
http://mp3.no


For reference, our setup is as follows:

We run an apache server which forwards all requests to mp3.no:80 to
login.mp3.no:9090. In other words, we use apache as a proxy for the
ZServer. When we try to upload a file from our own computers (10Mbit
network connection), all is fine and dandy. But when modem users try, or
if we try with extraordinarily large files, we get the following error:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST
/artists/testartist/testtrack/add_mp3.
Reason: Error sending from remote server.
Apache/1.3.9 Server at mp3.no port 80

Well I am not a Zopeguru by far, so the only idea I have is that in the
worst case you can always use ftp to such the stuff out of zope, then edit
it, then push it back into zope with ftp.

Well this is really something ftp should work for; making backups. ;)

NS (4.72) goes up to I guess 40 MB or so in worst case here. Just restart
it every day and it should be fine. Also, RAM is cheap (ok not as cheap as
it used to be a year ago, but anyway), so make sure you have 128 MB of ram
or more in your machine.

Mozilla is way cool, but it's still alpha so use at your own risk. I found
it is almost, but not quite, ready for real use.

Hello, 

we have some strange problems with the "SiteAccess"-Product. We are
building up three web-applications on one Zope-Server and three different
domains. Everything works fine with the "Site-Access" but if you have more
than 5 requests at one of the sites the speed gets very slow and you have
to wait about 3-5 and more seconds to get back a simple dtml-document.

We made some tests with the __no_before_traverse__ in the url and found
that there isn't that speed-problem if we access the documents direct
without use of the virtual-hosting.

Has anybody the same problem or an idea how to solve this ?

on win2k i used to use InternetExplorer 5 , but it is
incredibly annoying when the backspace-key is also the hotkey for
'back'; i guess you can see what problems might arise
from this when you accidentally unselect the textfieds when
deleting text, and press backspace a couple of times and end
up 3 pages back in history..

I have found Opera 3.6 to be by far the best browser for
zope-management. It is quick, lightweight, and usable with
full keyboard-access, but it costs money, and allegedly the
linux-version stinks (haven't tested it myself)

Hi Petr,

I found the solution to your problem:

Zope here behaves different, depending on if it's running in normal or in
debug mode ("z2.py -D"). The deb package start up Zope in normal operation
mode, while the binary release's start script starts up Zope in debug mode.

When used in debug mode, Zope appearently doesn't cache extensions,
therefore you don't need to tell it that the module has changed. In normal
operation though, it seems to cache them, so that you have to "edit" the
method to tell Zope something has changed.

As I said, I guess it's a performace question and therefore an intended
feature. At least it's no bug in the deb ;-)

Actually, that isn't quite the point.  He isn't actually arguing 
for AOLserver's superiority over every other system, and somewhere
(but I can't find exactly where) he suggests instead:

     Your development technology doesn't matter.

I wish more managers knew this.  You can build interesting
applications in Zope.  You can build them using Java servlets, or CGI,
or WebObjects.  No tool is going to magically solve all your problems,
and solving them will require familiarity with your tools, hard work
and careful effort, no matter what you use.

We had a manager here who was quite enamored of Java, and early on we
wrote some stuff in Java servlets.  He viewed our Zope work as just
stopgaps on the way to Java code that would carry us into the
long-term, but every time I asked "What problem would be solved by
rewriting all our Python code into Java?", there was no clear answer.
Unfortunately, far too many people in business computing follow
a similar management-by-white-paper-and-press-release style.

Similarly, Greenspun argues that you shouldn't re-invent databases; it
would require a tremendous amount of work to add to your home-grown
system all the features that existing databases have -- fancy query
optimization; storage across several devices; on-line backups;
federated operation; etc...  So use an existing system; Greenspun's
preference is Oracle, but he doesn't argue it like a law of nature.

No, you're not wrong; I did have this problem.
Adding /usr/local/lib/python1.5/lib-dynload to LD_LIBRARY_PATH makes
everything behave much more sanely.  :^)  I wasn't able to import
standard python modules (like socket) before, now I can.

And yes, this was a problem with my basic python installation, but
since I'm only using Python to run Zope, I hadn't noticed.

Unfortunately, this doesn't make things better.  :^(  When I run the 'start'
script, I still get the same error:

$ Traceback (innermost last):
  File "/opt2/local/zope/Zope-2.1.4-src/z2.py", line 436, in ?

PyImport_ImportModule: referenced symbol not found


Here's the part I don't understand.  I started stepping through z2.py (isn't
open
source wonderful?!), and trying the import commands one by one in a normal
Python interpreter.  They all succeed, including the one on line 436 which
resolves
to "import Zope".  Yet it doesn't work from within the 'start' script.

Oh well.  I just verified that I can set up Apache+FastCGI+Zope on my
Solaris2.6
box just fine with the binary distribution.  Am I correct that I should be
able
to set up FastCGI using a TCP socket that isn't localhost, and therefore be
able
to run Apache on our 2.5.1 box and Zope on a 2.6 box?  This would let me get
started
using Zope while I figure out how to install from source at a little more
leisure.


Thanks for all your help,

Not a stupid question, and not simple, either.  There are two ways to do it,
and choosing one over the other can be difficult.

1. Store the absoulte_url() of the referenced object, and run this through a
dereferencing method whenever you want to grab it.

Advantages:  If you really want a reference to a *location*, as opposed
to a specific object, this is the way to go.  That is, if you might delete
or
move the object, replace it with another one with the same name, and
expect the reference to refer to the new object, do this.

Disadvantages:  If you expect the reference to follow the object around
if it's renamed, don't do this.  It has to climb up the path to the object
instead of just grabbing it directly

2.  Store the object as an attribute of the referencing object.  This has to
be done (I think) from an External Method, since you *aren't* setting a
property.  You do something like "self.fooref = self.path.to.other.aq_base"
which DTML doesn't allow.

Advantages & Disadvantages: The inverse of #1

Architectures like Oracle with Vignette running atop it are very

Yes, it's a shame, because this model introduces yet another way where
you have to partition your "cloud".  It shouldn't matter what processor
or network gets added to your website "cloud".  Just keep throwing
capacity into the cloud.

Existing scalability architectures have such a schism along the
three-tier boundaries that it takes wizards to implement and operate
them.  Making them, obviously, brittle and prone to problems.

It will certainly take some time.  But obvious things can be solved as a
higher priority.  Since scalability means different things to different
people, though, there isn't One Answer.

I don't feel that advances in Python are absolutely required.  Apache
doesn't have a threaded model (before v2), and if Zope could dish out
requests like Apache 1.x, everybody would be awfully happy. :^)

This begs the question: how fast is fast enough?  These stupid PCWeek
tests, that give MTS a higher performance score than WebObjects because
it claims to do 4,000 requests/sec vs. 2,000 requests/sec, are just
ridiculous.  At 150 requests/sec, you're talking about the top one
percent of websites on the Web.

The other worry is that these super-freaky Python advances will require
cooperation from the app developers to keep the train on the tracks.

Again, I'm not so sure this is the big answer.  I don't think there's a
lot of evidence that Medusa/ZServer is the primary bottleneck.

Yep, this is ultimately an attractive architecture.  Particularly when
you pour all three tiers (presentation, logic, data) into it, you get a
single facility for scaling and distributing all three.

Right, though I'd encourage you to instead speak in terms of the goal,
rather than the solution.  Is the goal here to solve the 2Gb problem on
Linux/x86, to "limit corruption", or is it to do resource accounting on
a per user basis?  As Jim has pointed out, if your goal is the latter,
you won't get there -- user data can still appear in global things like
catalogs.

Jim's counterproposal, which he claims is easier than doing accounting
across separate Data.fs files, is to finish putting accounting hooks
into the object database.  Whenever a user exceeded their capacity (no
matter where the object), an exception would be raised.  This would
probably require that people be able to do their own packing.

I gotta admit, I'm awfully intrigued by this.  It is the kind of thing
that is _seriously_ compelling vs. other architectures, where you have
to keep on-disk quotas for presentation and logic, and in-RDBMS quotas
for data.

Still, the point is, make sure you speak in terms of goals first.

Doubt it.  There's still so much more, such as data scalability (vs. raw
performance).  As for the latter, we at DC _still_ need to make raw
performance go up.

Personally, I think a very smart caching system (where subtemplates are
pre-rendered in ZServer and know when the objects they depend on have
changed) is a huge win for a significant portion of high-load
situations.

Right.  Does this, though, limit them on the platforms you run on
because of assumptions in the threading model?

Right.  But again, this begs the question: what is a "nice site"?  What
if the goal of a "nice site" could be met w/out the disruption of
rearchitecting Python?

Is a "nice site" 100K hits/day?  A million hits/day?  Ten million
hits/day?

This steps into the next part of the problem.  To date, few in the Zope
community has been willing to publish any numbers for highly-traffic'd
sites, despite pleas even from our board chairman.  Perhaps that means
there aren't really any sites where Zope's limit has been reached?
Probably not.  But why are people so reticent to go on the record with
their hit logs?

But it _does_ mean that, until folks are willing to come forward and
provide numbers and test conditions, that we'll be working without a
map.

Subject: [Zope] Python equivalent of dtml-with?
Message-ID: <4.2.2.20000306100755.00b7bc90@saladin.aisys.com>

I'm writing an external method in Python which is going to be used to 
create new instances of a ZClass that I've written.  In my normal DTML for 
object creation, I would do something like this:

<dtml-with "ZClass.createInObjectManager(REQUEST['id'], REQUEST)">
    <dtml-call 
"propertysheets.instanceProperties.manage_editProperties(REQUEST)">
    <dtml-call unindex_object>
    <dtml-call "manage_editCataloger('MyCatalog', REQUEST)">
    <dtml-call index_object>
</dtml-with>

I've got an external method written which is able to create a new object by 
calling the ZClass.createInObjectManager method.  However, I'm not sure how 
to code up the code contained in the dtml-with block using Python.  I 
suspect that I could get things to work for the example above with 
something like this:

(self is the product containing my ZClass definition)

newobj = self.ZClass.createInObjectManager(REQUEST['id'], REQUEST)
newobj.propertysheets.instanceProperties.manage_editProperties(REQUEST)
newobj.unindex_object()
newobj.manage_editCataloger('MyCatalog', REQUEST)
newobj.index_object()

However, I'm interested in knowing how do code up stuff in Python which 
would take into account acquisition.

Thanks.

(AFAIK, the ObjectManager (base for folder) uses this mechanism too.)

Was just wondering, why the 'aq_base' part is required ? What could go wrong if
I just had self.path.to.other ?

Subject: [Zope] Refactoring Question
Message-ID: <4.2.2.20000306104328.00b75dc0@saladin.aisys.com>

I have a DTML method that I would like to refactor but I'm unsure of the 
results I'll get.  In one of my products, I have a ZClass_add method which 
has code which does something like this:

<dtml-with "ZClass.createInObjectManager(...)">
     <do something>
     <do something else>
     <dtml-call unindex_object>
     <dtml-call "method_editCataloger(...)">
     <dtml-call index_object>
</dtml-with>

What I would like to do is yank all the content out of the <dtml-with> 
block and put it in its own method.  I'm thinking that I would like the 
method to live in my product folder, but I'm open to suggestions.  The end 
result would be something like:

<dtml-with "ZClass.createInObjectManager(...)">
<dtml-call initObject>
</dtml-with>

and the initObject method would be contain

<do something>
<do something else>
<dtml-call unindex_object>
<dtml-call "manage_editCataloger(...)">
<dtml-call index_object>

My first question is, if I create an initObject method in my product 
folder, if I call it from within my dtml-with, will it execute exactly the 
same way as if it were included inline or would it somehow lose the fact 
that it was executing in the context of the "with" object?  I'm thinking 
that the "with" information is put on the namespace and the namespace will 
be available with my initObject method is executed, but I want to confirm 
that my thinking is correct.  Alternatively, should I define my initObject 
as a method of the ZClass itself rather than defining it in the Product folder?

Thanks.

There is a "deprecated" way of doing it, but the thread got off track
without a real answer (the "right" way). The "deprecated"  (the

ZScheduler. It works like this:

In __init__.py module:

# use the old method to set the icon for the ZSchedule object

In class definition.

Subject: [Zope] Authentication - login/logout
Message-ID: <38C3DBD4.A31D2482@ep.newtimes.com>

Does anyone know how to logout a Zope user?
Basically I need to be able to force an authenticated user back to the
'Anonymous' user
programmatically. (when someone presses a logout button, etc.)

Also, how can I change the message text in the login popup window?
Currently it says something like, "Enter username for Zope at
foo.bar.com:"
I would like to be able to modify this depending on where someone is
logging in.

I'm trying this on SunOS 5.5.1, and am getting more less the same
results. See my other article [Problems Installing Zope]...

I have tried adding both the python dynload directory, and even
the Zope/lib/python directory to LD_LIBRARY_PATH, both of which
are no help.

The error I get is a little different:

File "/new1/misc/Zope-2.1.3-src/lib/python/ZODB/__init__.py",
line 85, in ?
  import sys, ExtensionClass, TimeStamp, cPersistence,
Persistence
ImportError: No module named ExtensionClass.

As mention somewhere in this thread, this all stems from line 436
in z2.py :)

Any ideas?

   Strange. Just a check: you wrote '-appConnTimeout 0', aren't you ?
mod_fastcgi is case sensitive (or at least it seems so at the first glance at
the source).

   No, they are only used to report to the webserver. As stated there,
mod_fastcgi doesn't even ask for them.

This is true, he doesn't necessarily argue for the superiority of
AOLserver vs. the world, and that is not what I said either. However, he
strongly advocates for AOLserver, which is fine it is good work. But he
and others who follow have also advocated against extending AOLserver
for tools other than Tcl/ACS. He says, after all, what for?

This is true, but it isn't wrong to want to do your job with a tool you
enjoy. In the event that there are multiple qualifying ways of doing a
job within reasonable means of quality, I think a tool you like and
enjoy would potentially help and enable productivity. There is not
necessarily any magically programming language or tool. However, some
are better than others. Programming well, requires effort and work.

Because something requires effort, even tremendous effort doesn't mean
it isn't worth it. Because something may duplicate features of another
product doesn't mean it isn't worth it. Linux did all of this.
Tremendous work and effort to somewhat duplicate available software. At
some point the efforts which could be perceived as a duplication of
existing software may at some point supplant and exceed the currently
available existing systems. Subsequent versions of many existing
software packages can also fall into this same description of tremendous
effort, to duplicate the features of existing software. But this is
generally for a reason. Some times to improve certain things,
performance, add features, interoperability, portability, etc. I'm sure
Oracle has done this. I'm sure Philip has.

In his forum and other writings Philip has openly argued against most
any potential competing database to Oracle. In his argument he believe
the price of Oracle isn't/shouldn't be a problem. However, to many
people it is. Even though his webserver of choice is db agnostic, his
software ACS isn't. It is very much hardwired to Oracle. Talk to the
people involved in the ACS port to PostgreSQL.

Any advancement of technology will come at a price of tremendous effort
and duplication of current capabilities and features. Sometime it's
worth it, sometimes not.

Philip is right on many of his points. How much has software really
advanced from the capabilities in Lisp from so many years ago? Very
debatable.

As I said his book is a very good read, great material. I like many of
the business ideas and practices of ArsDigita. I have populated my
library with many of his book suggestions.

I have absolutely nothing against Philip, ArsDigita, AOLserver, ACS,
Tcl, etc. AOLserver/ACS is a great tool and toolset. However, in the
discussion of comparing AOLserver/ACS (really ACS) to Zope it basically
boils down not as much to features but to design/architecture of each
tool and scalability. Some people will prefer the ACS way over the very
OO way of Zope, some the opposite. If you are agnostic on such, then
scalability may become an issue. AOLserver/ACS and Zope scale
differently. Philip has a distinct view scalability. Farms, clusters,
no. Single machine, multi-processor, yes. Database == Oracle (his other
uses were also big $$$dollars). Hence scalability == $$$dollars.

AOLserver/ACS currently scales better than Zope. Zope may not currently
be the best choice, or a choice, for Amazon, Ebay, etc. But I think it
can someday. Because Zope is reasonably db agnostic (it does like
transactions), it may be a better solution for many people than ACS
since it is tightly linked to Oracle. If your money and data is
somewhere else you would have to port. In their forum I made comments
that it would be great if ACS were decoupled from it's specific database
dependency. The db connectivity could be abstracted and an appropriate
database api could be created. This would enable other database users to
use ACS. No interest from ArsDigita. Instead there are various peoples
rewriting ACS for their db of choice. As far as I know all hardwired. :(

There is definitely room for both to be successful, and others like
Enhydra. Then there would quality choices for users of various
backgrounds and personal preferences.

There is most definitely a give and take among the choices out there for
languages, webservers, app servers, etc. As for me, when surveying the
landscape from my world view and perspective, the other options
primarily potentially beat Zope "currently" in scalability/performance.
But for me Zope won other areas. I like Zope, I like ZODB. If I don't
have to use an RDBMS, I won't. However, I do hope for ZODB to improve to
the robustness and scalability of the RDBMSes. For some uses it is.

As I read the paper today and see 1 ghz Athlon machines becoming
available, Zope horizons are looking better. Go Moore go. :)

Subject: [Zope] Comparing "unsized objects" and strings
Message-ID: <38C3ED35.C507DF33@newopenness.de>

Hello all,

I have a little problem. I know where it is, but not how to solve it :-)

I have a DTML document:
---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- aid comes from the result of the externalMeth -->
</dtml-in>
---snap

Okay, no problem so far. But when I want to compare the value to a
parameter I have given to the document via a <FORM>:

---snip
<dtml-in "externalMeth(p)">
<dtml-var aid> <!-- Okay, works fine of course -->
<dtml-if "aid == param">
Hi there!
</dtml-if>
---snap

The expression evaluates always to false. I have traced the problem back
with an external method ("<dtml-if "equals(aid, param)">"). When trying
the "len" function on both variables, "param" is not a problem (it's a
string from the the <FORM>), but "aid" complains that it was an "unsized
object".

How do I compare them?

Thanks in advance
  Christian

hmm .. untested:

<dtml-if "_.str(aid)==param">

_.str(aid) should return a string presentation of aid.

Woohoo! Absolutely. :)
However, if a multi-threaded/multiprocessor capable Python were
available to embed into AOLserver then it seems to me that the improved
performance would be transparent.

This is true if the requests are evenly amortized throughout the 24 hour
period. Unfortunately they aren't. For me fast enough means that your
machine is not maxed out (or croaking) when handling peak loads. Your
visitors handle the speed/latency well. It is all very relative.

I agree. I was just hypothesizing. I would generally prefer to keep with

True and maybe not. However as Zope pushes into heavier trafficked
environments who knows. But we'll take whatever speed gains we can. :)

What I like about this is the capability of distributing your work load

Actually not necessarily either. I don't want data corruption, so if
that's an issue it will need to be addressed. Say for example I have a
very large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5gb directory which is reasonably stable
updated monthly.
ZAuto/manufacturers isn't so large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.

My example above doesn't fit into this situation, at least as far as I
can tell. There are no user quotas or explicit restrictions.

I have somewhat lumped raw performance and scalability together. In many
ways they are hard to separate. I agree a smart caching system would be
nice and a tremendous boon to performance. In Philip's writings, he
believes that performance is best when the entire db resides in memory.
Sometimes that is not possible. However, if you cache the most often
accessed parts you reap tremendously.

I don't know, I am not a threading expert. However, with AOLserver, I
believe that stayed with the POSIX model. So if Python was such it seems
it wouldn't be a problem in most cases.

Yes, this is a very subjective area. My original problem with Zope's
scalability and what would scare me with a site is the inability to
throw hardware at it. ZEO didn't exist then. The question exists though
is if a Zope based website was getting 1 millions hits a day and gets
Slashdotted or some other such phenomena and in a few weeks or months
grows to 5 or 10 million, what are their options within Zope? Where will
the bottlenecks come from? Can they throw hardware at it? What if
tomorrow my "Slamazon" bookstore went online and was an instant success?

It does, but the "string" is still an unsized object. 'Scuse me, I
thought Python is not strong-typed?

I'd have thought someone would have answered you by now. Have a look at the
Zope Quick Reference:

  http://www.zope.org/Members/ZQR/

Also, looking over the doc/CHANGES.txt file can give you lots of clues about
new features that may not yet have been documented.

If I am understanding you correctly, you should have a look at Loren
Stafford's ZScheduler. Download it from Zope.org, and look at the code for
the ZEvents. They are catalog aware, and override manage_afterAdd, then call
the superclass method.

Hi,

What versions of Zope (probably 2.1.4) and what versions of MySQL work together?   I have tried unsuccessfully to get MySQL to work with the the MySQLDA using the latest stuff.

     Keywords:  Management Interface 

 Submitted by:  Dylan Jay djay@innocent.com
-------------------------------------------------------------------
 When I create a ZClass with my own management methods they 
 will by default use standard_html_header etc. This doesn't look 
 like the standard management interface. I think we should have 
 a standard way of making all management interfaces look the 
 same.  In fact this should be able to be changed for any subset
 of management interfaces so you could for instance change the
 way the standard zope interfaces look.

Dang!  Another "lead zepplin" topic!

Perhaps everyon was holding off because they expect that the
management interface is merely a short-term, necessary evil, to
be replaced RSN by:

 * The "Zope Studio":http://www.zope.org/Resources/Mozilla/index_html
   project, which uses Mozilla's way cool XUL technology to build
   "Zope-aware" chrome in the browser?

or:

  * The upcoming Model-View-Controller
    "re-archictecture":http://www.zope.org/Resources/Mozilla/ZWiki/ModelViewController 
    project, which works to divorce the HTML presentation (the 
    "view") from the underlying Python objects (the "model");
    this is enabling technology for ZopeStudio, the 
    "ZIE":http://www.zope.org/Members/johanc/ZIE/ZIE-demo cognate
    for InternetExplod^Hrer, a wxPython and XML-RPC client like
    the one Amos Latteier
    "demonstrated":http://www.zope.org/Members/Amos/XML-RPC 

or:

  * The "Portal Toolkit":http://www.zope.org/Products/PTK, which
    replaces much of the current management interface with new
    "wizard"-based configuration tools.

I'll close by thanking Dylan Jay for suggesting the topic, and
for his thoughts on potential solutions.

Keep those cards and letters coming!

     Keywords:  ZClasses 

 Submitted by:  Tres Seaver tseaver@palladion.com
-------------------------------------------------------------------
 When building a Product using ZClasses, I often want to create
 a "root" ZClass, which the manager will create in a normal
 folder, and which will then expose the Product's other ZClasses
 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel
    +- FooProduct
       + FooItem_add_permission
       +-FooRoot
         +- FooItem
         +- FooItem_add

       + FooRoot_addForm
       + FooRoot_Factory

Hi everyone,

I'm asking this question again because I still haven't been able to work
it out for myself. I'd like to have a button or link on a page that, when
pressed, presents the user (the Manager actually) with a dialog to upload
a new version of a file object that's in that directory. I presume that
the manage_upload method would do the trick, but I can't figure out how to
use it.

The file object I want to update is called 'Bookmark.htm'. I'm trying to
make it easy for our school librarian to distribute our standard bookmarks
to all of the machines in the building.

ZCache caches method results.  It's kinda broken and not very extendible. 
I'm writing GenericCache as a replacement, but it'll only be finished when I
have enough time.

Subject: [Zope] Listening on specific interfaces
Message-ID: <7502CAC76F59D211B0090000F8662FA305F43EE7@ap3expr3applge.appl.ge.com>

All - After bringing up a logical interface (hme0:4) on physical interface
hme0, Zope will not work if I try to use a value of 80 for the HTTP port.
Netscape Enterprise Server is running on this same box and is already bound
to the physical interface hme0 listening to port 80.  My guess is that Zope
is not really binding to the virtual interface, but is trying to bind to the
physical interface and thus it is conflicting with NES.  The error follows:

$ ./start -a 3.130.232.27 -w 80 -f 8021 -m 8099
Traceback (innermost last):
  File "/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/z2.py", line 493, in ?
    logger_object=lg)
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/http_server
.py", line 552, in __init__
    self.bind ((ip, port))
  File
"/opt/devnet-zope/Zope-2.1.4-solaris-2.6-sparc/ZServer/medusa/asyncore.py
", line 205, in bind
    return self.socket.bind (addr)
socket.error: (13, 'Permission denied')

3.130.232.27 = hme0:4

If I specify an HTTP port that is not currently bound to the physical
interface (hme0), such as 1234, Zope starts up properly.

How can I force Zope to bind to logical address 3.130.232.27:80 so that it
no longer conflicts with NES?  Is this even possible?  I have a few Zope
apps. that I would like to bind to different logical interfaces on port 80
so that I can use different hostnames.  Additionally, I do not want the
user(s) to specify a port in the URI.

Thanks,
-Brian

I have Oracle 8i for Linux. When I tried to compiled the ZOPE DCOracle
interface, I got errors about the missing library 'netv2' which it seems
is supposed to be part of Oracle. Does anyone know why I might not have
this library or how I can get my hands on it?

LoginManager is a thing that aims to replace user folders.  It accepts
plugin User Sources (which know about users) and Login Methods (plugins
for different methods of logging in -- things like Basic Auth, Cookie
Auth, etc).

You can get it from the ZopePTK CVS. (It's useable without PTK, though
-- there's nothing PTK-specific about it. It's just that it's
particularly useful for PTK)

LoginManager currently comes with a default User Source called Generic
User Source (GUS), that is a GUF-like roll-your-own system.  It uses
GUF-compatible methods (userExists, userRoles, etc), so converting any
GUF-using site to a LM site should be pretty easy.  We plan to write
another User Source that is a simple ZODB-based plugin that parallels the
current plain User Folder.  Other existing User Folders (etcUserFolder,
etc) could/should be converted to user sources. 

One advantage is that you can have more than one user source, so if you
need to have employee logins from your corporate LDAP directory and
customer logins from your Oracle database, you can do that. The
implementations of each can be completely separate and reuseable.

Another advantage is that there is no longer the "n times m" problem of
login methods.  If someone writes a PostGresSQLUserFolder that does SSL
client certificates, there's no easy way for you to use that SSL client
certificate capability with etcUserFolder.  But with LoginManager, if
someone writes a SSL client certificate Login Method and someone else
makes an etcUserSource, they automagically work together.

There are some other cool features too, and more coming.

By the way, for those of you who were at IPC8 and were confused by the
RIPP Patterns talk (which is everyone who attended, I think ;->),
LoginManager is so far a good example of at least the RI part of it.

LoginManager is the Implementor for users (it's just called acl_users
instead of I_User :->). User Sources are really Racks. 

The "things from different authors automatically work together" nature
of LoginManager is exatly what RIPP is for. Now that we have an example,
maybe we can try to explain it better and get other people using it for
other things :-)

Despite your following (very good) points, this is not true.  It leads
to conclusions like "Perl is just as readable as Python", "Let's just
use C, it can be made as portable as Java", "We should use Lisp for
this 3D first-person shooter, we just need a better algorythm than
previous C implementations."

A better way to phrase this is:

	Your development technology is only one piece in a larger
	puzzle.

I've recently switched a rather large project from Java to Python --
throwing out nearly 2 years of work in the process -- and I have
noticed an immediate increase in development speed.  Changing
development technologies was a GREAT idea; but only because it was
considered within the framework of the developers we had, the skills
they had, and the relative advantages of both frameworks.

The project had a high dependence on lists and hashes.  Changing to
python increased performance (all these data-types are native in C, in
python; profiling our code shows that it spends most of its time
inside java.util.Hashtable), scalability (Java has lots of hard limits;
a max of a few thousand interned strings, 32M of RAM per process unless
you start diddling command-line arguments, and GC gets unbelievably
slow if you do that), reliability (the JVM on Linux is buggy; python is
pretty robust if you're not using any crazy native modules ^_^), and
last but not least, we get the source to our tools so we can improve
them ourselves.

Certainly, nothing is a magic bullet or a panacea that will make all
your development problems go away, and I doubt that anyone reading this
list believes that.

Coincidentally, if you are, and you do, I have a GREAT WAY to MAKE
MONEY FAST with NO INVESTMENT!!! It is NOT MLM!! ;-)

This is a great point.  Considering the technology within a coherent
whole is EXTREMELY important, and the view of some managers that
something is just going to be a panacea that resolves everything is
depressing.  It's not limited to development technologies though -- it's
"employee empowerment", it's "diversity training", "thinking out of the
box"... bad management transcends the boundaries of space and time =)

In my experience (I admittedly haven't read this particular article)
Greenspun's advocacy of Oracle and WebDB is near-rabid and biased
toward extremely high-end applications for people with lots and lots of
money.

What you're referring to as "re-invent"ing, by the way, is referred to
by some as 'innovation'.  However, I will agree that the time to do
that is not necessarily when a large project is nearing a deadline...

Finally, I think Zope is a great tool, and for some applications (making
a Slashdot clone, for example) it DOES have the kind of killer advantage
that can make it worthwhile to switch lots of work in another system to.
 It all depends on what's appropriate though -- if, for example, your
site needs to have access to AdaBase, I don't know if Zope is the best
way to go.

I have actually seen projects for which CGIs written in C++ were
unquestionably the best choice.  Examples like that are rare, but they
do exist.

Hi,

I'm running Zope 2.1.14 on Redhat Linux 6.1. I would like it to start 
automatically when the computer boots. I'm looking for a workable rc script for

I tried the script found on the How-to: Installing and Upgrading Zope 2.X.

You didn't say what problems, if any, you are having, so I'm just going to
take a shot in the dark.

By choosing a DTML Document, clicking on the Upload tab, and viewing the
source, I believe you need something like:

<FORM action="manage_upload" method="POST" enctype="multipart/form-data">
<INPUT type="file" name="file" size="25" value=""><BR>
<INPUT type="submit" value="Change">
</FORM>

Make sure you don't leave out the enctype attribute or things will be
unhappy.

Let me know what, specifically, doesn't work if you continue to have
problems. I'll do my best to help.

Out of curiosity, are you running (lauching) Zope as root? The lower ports
(below 1024?) are privelaged on UNIX, and require root permission to bind.
Higher ports, such as 1234, are not; anyone has access to port 1234.

We have a Solaris 2.6 box here running Zope 2.1.4. We launch ZServer with
the -a parameter specifying our interface, and it works like a charm. I
suspect this is not interface related.

Look at the management form that you see when you create a File object, and
do what it does, only in the context of your user interface.

Thanks Jeff...that was the problem...all of my Zope instances until now have
been started by uid zope.  Rather stupid mistake, but a learning experience
nonetheless.

Thanks again,         -Brian

Anywhere inside the "main" folder, you should be able to write <dtml-var
expr="sub.message">.  Outside of "main", you would have to write <dtml-var
expr="main.sub.message"> or possibly <dtml-var
expr="f1.f2.main.sub.message"> if "main" is in "f2" is in "f1".

If I'm understanding the problem correctly, try:

Wade, the best you can do with basic authentication is to do something
like:

<dtml-raise Unauthorized>
 You are logged out.
</dtml-raise>


However, if the clicks cancel on the login box that pops up (there's no
way to prevent it from popping up), he or she will still be logged in.

Use cookie-based authentication if this is a constraint.

You can use the environment variable Z_REALM to change "Zope" to
something else in the login box text.

This looks right.

Acquisition is built into Zope objects; the only time you should ever have
to "take [it] into account" is if you are trying to acquire an object with a
non-identifier Id, or whose Id is stored in a variable.  In these cases
"anobj.aq_acquire('foo.html')" and "anobj.aq_acquire(fooname)" should do.

Yesterday I had to restart NS no fewer than 5 times, to prevent the
'swap-to-death' situation.  I have 96M in my machine, and i've been careful to
eliminate all extraneous tasks to reduce memory usage.

Yes, memory is cheap, but to get this box to 96M (from the original 32) took
quite some wrangling, since it seems ordering more RAM here can have at least
an 8 day lead time, amongst other things.

As a programmer myself (ZOPE is like a holiday :) I know that memory leaks can
be easy to code, and tiresome to track.  But in an application as large as
Netscape, I would hope for slightly tighter quality controls, and a little more
coding discipline.  There are some fairly simple guidelines you can follow to
write "zero resource loss" programs.

Yes, I looked into Mozilla yesterday.  However, I discovered it will ONLY work

don't have ANY other apps using it.

Greetings,

I have used MySQL 3.22 (Stable) and 3.23 (Development) with Zope 2.0.1 through
2.1.4.

I am currently using them with the ZMySQLDA version 1.1.3, along with MySQLdb
version 0.2.3.  There is a very good howto on installing these.  I have
recollections of compile problems on my first attempt, but it turned out I was
tryring to compile something that was obivated by MySQLdb.  So, follow the
instructions carefully.

Subject: [Zope] Frequent Zope Restarts and GUF authentication
Message-ID: <m3k8jf4svq.fsf@wacko.pdx.net>

I have a server that is being run in production mode without the
-D flag.  The server processes die after about two hours.  I haven't
seen the actual crash yet nor have any users complained about error
messages.  I know the server is restarting because the Control_Panel
tells me so.

Well, the real problem here is that since my site is protected with
GenericUserFolder in cookie mode, GUF's cache gets wiped when the
server bounces.  This forces my users to log in again.  

Two questions, 
  Any guesses as to what's causing the mysterious restarts?

  Any idea on how to resolve the GUF problem?

Zopists,

Has anyone else noticed that the endmail tag will sometimes not send a

In this context 'cache' is the in-memory cache of Persistent objects
(most objects in Zope are persistent, for example, just about everything
you can add or manage in Zope is persisent).

Obviously, it's not very good performance to read and write all objects
to and from the database everytime you use them.  Therefore, there is a
cache to speed this up.

The 'target' is the number of objects in the cache.  Note that this is
not a very hard limit, ie, if you set it to 10, it will let you load 10
tiny objects or 10 huge ones.  Or 10 of mixed size.  Experimenting this
this value and watching how much memory Zope consumes is a good exercise
in performance tuning.  Note that there is NO magic value here, you have
to play with it.  Keep in mind that the default is very conservative,
you can definatly start playing with it in the up direction (unless your
running on a 386 with 16MB of RAM...).

I am also trying to get MySQL running with Zope 2.1.4.  I'm trying to follow
the HOWTO by "alanpog."
I got to the part about Expand and Install MySQLDB but I am stuck.  In the
installation README, it says to read Setup.in to verify the paths.  I have
no idea what those paths or for and I don't have them on my Linux system.

Does anyone know what these paths are for and how I can determine what I
should set them to?

I have MySQL 3.22.32, I'm trying to install MySQLdb 0.1.2 and ZMySQLDA 1.1.3
per the alanpog HOWTO

Curtis, what is the really good HOWTO you mentioned?  The one I found is
very brief and isn't helping me much.  Also, where did you get MySQLdb
version 0.2.3?  The latest I saw was 0.1.2.

David, did you manage to get past the Install MySQLdb step?

Thanks,

Eric.

Hi,

Something that seems maybe very trivial, but I did'nt find the solution.

I have a very simple class ItemId (metatype ItemClass) which is only a
subclass of Image and has no property sheet.

When I try to create a new instance I get the following message : 

Error Type: TypeError
Error Value: argument file was ommitted

Here is my addMethod:

.......
<dtml-with "ItemId.createInObjectManager(REQUEST['id'], REQUEST)">
<dtml-call manage_upload(REQUEST['myimage'])

</dtml-with>
......

Where 'myimage' is the name of a field of type file in my input_addForm.
I works fine when I use manage_upload with an Image but not when it is a ZClass
subclassing an Image. Where am I wrong?

Thanks.

Thanks, that sounds like what I'm after.  I don't quite understand why
this is not setting a property.  Can you point me to some documentation
that might help explain the difference?

I guess putting in a little Python is no big deal, but it does break my
ultimate goal of letting non-technical people create new classes of
content.  Is there any plan to add inter-object relationships to ZClasses?

what about the options in fastcgi?  processes in FastCgiServer defaults to 1. 
-maxProcesses defaults to (50)  >-maxClassProcesses defaults to (10)

will increasing these numbers help stop connection refused error?

fastcgi is a like a black box to me, full of mystery, even after reading the
docs.

I hope you got your setup working, Jeff.  Your rewrite rules look
good to me.  But I want to take this opportunity to make a (tested)
alternate suggestion for the rewrite rule.  The above rewrite rule
has the unfortunate feature that URLs like ".../Zopestuff/etc"
match the rewrite rule and get turned into the (not found) path
.../cgi-bin/Zope.cgistuff/etc.  This isn't a problem normally, but
you can perhaps imagine having Zope under a directory with a given
name but wanting another URL with that same name as a prefix
substring to also work (.../news and .../newsimages perhaps?).
I've come up with what I think is a better regexp for use in this
kind of rewrite rule, mostly to avoid the surprise factor of later
having a Zopestuff type URL mysteriously fail to work on me someday:

.../Zope(/.*)?$

which is mapped to

.../cgi-bin/Zope.cgi/$1

The ?$ means that the /<stuff> all the way to the end of the URL is
zero or one time.  So Zope by itself matches, and Zope followed
by a / matches, and Zope followed by /stuff matches, but Zopestuff
does not.

FWIW

If MySQL does everything you need, it is probably the better choice.
GenericUserFolder is more complicated to setup (so it appears better
supported as their are more questions), and exists to support sites
with more unusual requirements.

an acl_users folder only authenticates the sub-tree it is defined in.
If you want AUTHENTICATED_USER available in /home, then move your
acl_users folder into that folder. Your users will not be required
to login if they access stuff that is available to the Anonymous role,
but if they have logged in, AUTHENTICATED_USER will be set.

The problem line is <dtml-if "e">. What I was intending to do is
perform the code if the search result actually returned something, but
this doesn't seem to be happening. What I'd like to do is:

<dtml-if "len(e) > 0)">

But, len() doesn't seem to be defined in whichever namespace the code
is being run in. I tried:

<dtml-call "global len">

before the dtml-if, but this errored out as well. Am I completely
misunderstanding the problem which I'm having?

Thanks.

Good luck. :(

 Browsers and servers are neither required to, nor are (to my knowledge)
respecting any sequence of form fields. Basically, IME, if you need the
data going in somewhere to be in the same order ( a program that expects
certain values in certain a order, for example), have whatever processes
the returned data order it for you.

I've just been testing, to see when the most leaking occurrs.  It's definately
whenever I type in the edit box.  At one point I hit enter, and it grew by over
300K.  As I type, I can watch the size grow.  It's really that fast.

As I type, I am downloading the NS RPMs from RH6.2, which seems to be a few

Much appreciate the effort.

Someone even suggested it might be my Motif lib.  KDE, afaik, catches all the
Motif calls and replaces them with its own widgets.  A workmate running Gnome
checked the same situation, and the memory leaks in just the same way.

scratch another theory.

To use len, try:

  <dtml-if expr="_.len(e) > 0">

It is part of the _ namespace.

You may also be able to achieve the same result (depending on the types of

  <dtml-if e>

Ok, it appears that len() isn't what I want. I was under the
impression that searchResults() returned an object which functioned as a
list, but this wasn't right, apparently. Or maybe it was, *shrug*. :)
Here's my current code, which I've modified a bit for testing
purposes:

<dtml-var standard_html_header>

<dtml-call "setCalendar('valign','top')">

  <dtml-var dprop>

This code generates links as it should. What I'm trying to do though
is, if an object of the Event class exists with an event_date which
equals the current rendered date, I'd like to link directly to it. I can
successfully search for the date using the PTK's search form, so I'm
fairly sure that my issues with the catalog are resolved.

So, what exactly is being returned by searchResults, and how can I
determine whether my search yielded anything, so that I can display a
link to the item?

Not if you do not name them explicitly. The REQUEST.form.items() is a
python dictionary. Keys of a dictionary have no fixed order. You could
sort them if you wanted to, but that would be a computer order, not the
original order in which they appeared.

I had a system where it failed (also silently) every first time after reboot.

I just moved to an external method that used /usr/sbin/sendmail as I did 
not have enough time to start debugging. Telnet to port 25 had just a very 
long (>30 sec) startup time, probably some DNS problem. 

AFAIK Zope does not (for some unknown reasons to me) use pythons SMTPlib 
but has rolled their own smtp interface.

It has also been reported to fail with MS Exchange server, which someone 
fixed for himself by swithing to smtplib. IIRC the patches were also posted 
to zope or zope-dev list.

IMHO the right solution for Zope would be swithing to smtplib, and if there 
are faults then fix them there (and maybe include fixed smtplib with Zope 
until fixes are included in mail python distro). There is no need to invent 
to similar but slightly and differently broken wheels, at least in Open 
Source Software there aint.

Message-ID: <4.2.0.58.20000307085505.00c2ee80@195.60.12.162>

Dear Zopers,

I read Chris McDonough's How To on Gaining Zope Enlightenment by Grokking 
Object Orientation. It raised a few questions in my RDBMS-oriented head. So 
I mailed Chris with these questions but Chris explained he just couldn't 
answer them right now and asked me to post them to the list. They seem very 
basic, very fundamental questions to me.

So here is my email to Chris - If I get any answers here I would like to 
include my questions and your answers in a How-To to help those who come 
after me !

Thanks for any help !

Here's the original email

---------------------------------------------------------------------------- 
----------------------------------------------------------

Chris,
I enjoyed your How-To on Gaining Enlightenment very much. I've been using 
Zope for a couple of months now and I've made some progress - my first 
project has been to use it to give access to established databases over an 
Intranet. Like you I think its wonderful, but like you I keep getting 
stuck. Never mind, with the help of the mailing lists and long hours 
reading books on Python etc I've made progress.
BUT ... (there's always a but isn't there) - no matter how much I read and 
play around with OO - I still don't 'get it'. My background is many years 
working with relational databases on Unix - (and there are thousands like me).
I just don't get the bit about storing data as objects. Could we discuss 
this a bit more and perhaps publish my questions and your answers on 
Zope.org ?? This may help me and the thousands like me.
OK, you create your class of Spam, which has attributes of cansize and 
texture and it has methods that display these attributes. No doubt you 
could add other attributes, such as selling price and develop a method to 
increase the price by a percentage. OK so far ?
Now we create an object (which is an instance of the class Spam) - which we 
call myfirstcan. We can define the attributes for that object when we 
create it or later and we can use the methods defined in the Spam class to 
do so. OK so far ?

What I don't get is how you store and retrieve the objects you create. 
Let's go to a more realworld example - how would you implement a stock 
system using objects ? Let's take the simple table Stock which has three 
columns
Product_code Description Price
and we could enter rows of data into it, for example -
ABC Spluggifier 20.00
CDE Super-spluggifier 25.00

Now if I was writing a conventional database system I would maintain the 
above by defining a program which perhaps prompted the user for the 
required columns (Product, Description,Price) and then I would store the 
users input in a row in a table. Perhaps another program (the price change 
program) would use a stored procedure to allow price change. OK ?
Now in OO terms I see that I could create a class of Stock with attributes 
Product, Description and Price. I could create a method to allow price 
changes. Very neat.
Then I can create an object( i.e a particular stock item) by saying 
something like
product_1 = Stock(product_code="ABC", Description="Spluggifier", Price-"20.00")
Now I can create another object by saying
product_2 = etc
but that is not the way you would do it surely. You would be effectively 
'hard-coding' each product in your system.
Surely you would have a program which did something like
WHILE the user is entering data
PROMPT user for data
VALIDATE data
WRITE data to database
END WHILE
How do you do that in OO terms ?
How then do you search and retrieve an object with a particular value of 
product_code ?
How do you write a program which updates the price of all stock items where 
the product_code begins with AB by 2%.?
Thanks for reading this far. Hope you can stop my head spinning !

Regards

Richard

I'm still having difficulty with this.

I want to add a date to a character string ( dated user comments ) to
store into a sqltable.

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">

The docs say that this returns a date string ( as opposed to a date
object? )

<dtml-call "REQUEST.set('mystring', 'date: '+CurrentDate)">

produces this error

Error Type: TypeError
Error Value: illegal argument type for built-in operation

And if I try this

<dtml-call "REQUEST.set('mystring', 'date: '+_.str(CurrentDate))">

mystring is then 'date:'

I have not obviously researched this in detail (perhaps you may want to)
but I do not believe that the any of the various web rfcs define that
either the client or server should send/expect any form elements in any
explict order, and that if any order is mentioned at all it is probably
'implementation defined'.  The introduction of various CGI interface
libraries for various languages probably munges this even further.  I
would not rely on any consistent order at all coming from any system.

We wrote the sendmail tag before smtplib was written.  At the time there
was no existing standard smtp client library in python.

a sequence of record objects that describe cataloged objects that match
your search query.  The are NOT the actual objects themselves, just
'descriptions' that can be used to refer to the objects (with 'getpath'
as you discovered, or 'getobject').

In your case, 

<dtml-if e> 
    There are results.
<dtml-else> 
    There are not results. 
</dtml-in>

I don't undertand what you mean, you code apears to do this.

BTW, it is much easier for other people (or at least me) to assist you
if they can read your code.  For python programmers, this means
indenting it sensibly.

You can do this, but you must be sure you understand that your object
now references the other object without the Zope framework's
'knowledge'.  This is not a bad thing and happens all the time, but you
should be familiar with what this does to things like garbage
collection, persistent object deactivation, and circular references.

I don't know what you were trying to do before, so I can't answer this.

You mean references?  We've thought about this problem a little and Jim
and I discussed this over Chinese buffet once, I obviously had less of a
clue than him, but I belive the result of our discussion is that there
should be some sort of standard for one Zope object to refer to
another.  The simplest way we could think of is simply storing the
path.  Such as:

attribute = "../../relative/path/to/other/object"

or perhaps:

attribute = '/absolute/path/to/object'

Then when you want the object you ask Zope to resolve that path for
you.  Currently you can use REQUEST.resolve_url(attribute) to do that
for you.

If you're not working on python you can simply set a string property as
the path.

This is how ZCatalog does it (actually ZCatalog uses a slightly dumber
version of this concept, don't ask).  HOWEVER, the lack of any kind of
standard or support for such references in the framework has bitten
ZCatalog (and webdav) in the past, and the decisions we made will
probably come back to haunt us real soon now.  You have been warned.

Hi,
Stephen Pitts <smpitts@midsouth.rr.com> posted a patch that may help you.
This patch replaces the socket-base code with smtplib calls.
The original MailHost didn't work with our Exchange 5.5 server, but after I
have applied the patch it works fine.

Subject: [Zope] copying image object?
Message-ID: <200003071209.AA19294@rsphy9.anu.edu.au>

Hi Zopistas,

A likely FAQ but it's late, I've been Zoping for 15 hours, ZQR 
is temporarily unreachable from Canberra, I can't see straight
and I'll admit it - I'd like to wake up to the answer ...

I simply need to copy an image object (image1) from my
globals folder to within an instance of a containerish 
ZClass.  I toyed with manage_addImage() but couldn't
find a method to get the raw data out of image1. 

Cheers,
Darran.

Subject: [Zope] Tricky usage of string to integer conversion
Message-ID: <000001bf8839$b997a5e0$0b00a8c0@nassau.islands.net>

I am trying to do the following:

<dtml-let x:int="REQUEST.get('prod_config')"
          item="_[REQUEST.get('prod_id')]"
          price="item.price_list[x]">
    <INPUT type="hidden" name="chargetotal" value="<dtml-var price>">
</dtml-let>

The prod_config variable is a number (returned as a string) from a SELECT
list.  The prod_id variable is the id of an object in the same folder as
this method that has a price_list attribute.  price_list is a list of
strings representing prices.

This results in a "Name Error" where Zope cannot find "x".  If I change line
3 to this:

          price="item.price_list['x']">

it fixes the Name Error, but then I get a "Sequence Index must be an
integer" error on price_list['x'].  I would have thought the use of "x:int"
in my <dtml-let> would take care of this issue.  Seems I can't win!

Does anyone know the correct way to do this lookup?

Brian Holdsworth

"dtml-let" doesn't understand type annotations, so you are setting a
variable called 'x:int', which isn't what you want.  You need to do the
integer conversion in Python, like so:

<dtml-let x="_.int(REQUEST.get('prod_config')" ...>

See the DTML reference guide at zope.org for more useful methods of "_".

I think it must be converted by the atoi method of the string module:

so either:

<dtml-let x="_.string.atoi(REQUEST.get('prod_config'))" 
          [rest of your code]
or:

<dtml-let x="REQUEST.get('prod_config')"
           item="_[REQUEST.get('prod_id')]"
           price="item.price_list[_.string.atoi(x)]">

This is the same problem as last time. You must CALL the Date method, not
just reference it. The above line should read:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date()">

Note the use of parens on Date().

Try it for yourself by putting the following in a DTML Method:

  <dtml-var expr="ZopeTime().Date">

You get:
  
  <method DateTime.Date of DateTime instance at 568eb0>

if you do a View | Source in your browser.

It does, if you CALL it.

Here is some code that works:

  <dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
  <dtml-call "REQUEST.set('mystring', 'date: ' + CurrentDate)">
  <dtml-var mystring>

Again, you've never set CurrentDate correctly. View the source of the page
that comes back and you will see the problem.

Hope this helps.

It supports it to no greater or less extent than Linux does.  The
standard library defaults to using an int or a long for *seek calls.
The difference is semantic only, as they're both 32 bits on both
systems anyway.  Even if you assume unsigned (fseek is signed), that's
still 4gb, max.

However, on my Linux/Alpha system, a long is 64 bits.  This
effectively removes the problem.

I submit, therefore, that you are not seeing a Linux problem, but an
x86 problem :-)

Why?  This is overkill for what zope is.  Zope is not, in essence, a
web server.  If you want to do strange things like that, use Apache
:-)

Completely inaccurate.  Proprietary software (Please, use the Jargon
file next time you look something up in the dictionary, geez) is
software which is not licensed under a Free Software license.  This
includes Java *as implemented by Sun* but NOT DTML or Free
implementations of XML.

Well, the issue is not really "the language".  The issue is whatever
software implements it.  Anybody can implement DTML, or Java, or XML,
or whatever, and license it however they want.  The question is,
whether this implementation is Free Software, and indeed, it is.

Interesting point.  I myself prefer Perl to Python for a number of

Untrue. Apache's load/stats and Zope's load/stats are different sides of
different coins.

You're implying that Zope has no statistics to export, and that if you
couple Zope with Apache (which you might not want to) then the numbers
that Apache can export would apply to Zope -- and this is clearly wrong.

Thank you for completely sidetracking me and instead choosing a flame
angle for petty word games.

My point specifically was that the mass of mainstream appreciation of
Zope versus a product like Dynamo was specificially _not_ related to
openness. IBM does not open its money floodgates to invest in Linux
merely because Linux is an open technology -- Linux was not the first,
nor the last, not arguably the finest open technology in the history of
IT. It and others do so, and give momentum to Linux, because of money,
pure and simple.

Let me relate a short anecdote for you, about the incident which
triggered this thread. See, my colleagues are currently involved in a
large project for a large company. They are buying Solaris 8 to run
Dynamo. I've made a very strong case for Linux and Zope.

There is, today, only a marginal difference between these two setups,
and that difference is in price: The Linux/Zope combo is significantly
cheaper than the Solaris/Dynamo combo. This has zero bearing upon their
choice, and indeed on most ordinary computer investments for any
company: The cost of buying a computer and licensing the software is
"nothing" compared the maintenance costs and the insurance a big company
needs that their investment is safe. In other words, heavy support plans
and brand names.

And guess what? Despite the fact that both Linux vendors and Digital
Creations offer such support plans, my advice to my colleague and this
company falls dead on the ground.

Zope doesn't have the flashy packaging and sexiness of a product line
Dynamo -- which, actually, I strongly urge you (and everybody else in
this forum) to experience yourself, before you snap back at my again --
and this affects management decisions. Dynamo is exceedingly sexy, and
it boasts the kind of bullshit magic that have management and tech
people alike drooling.

So is it "their problem"? In the end, I don't think so. I think they're
going to be quite happy with Dynamo.

As one of my colleagues pointed out, the problem starts with the name.
(Somebody out there is hyping what they call Linux' next-generating GUI.
And it's called... GNOME. What's wrong with this picture?) I don't care
myself, but I recognize the problem.

I don't claim to be an OO master or a ZOPE master, but I'll give this
a shot anyway and share some recent revelations I have had about OO in
general.

First off, the examples that people always use to demonstrate OO
concepts wind up being more distracting than they are worth.  For
instance modeling a can of spam in OO.  That would be a logical thing
to do, if you were writing a control program for a can of spam.  But
NOT if you were writing a database app!  This, I think is one of the
most confusing parts for database programmers coming to OO.

Second, so if you don't model your can of spam, then what DO you
model?  Well, you model *your data* and if your data is a database,
then that's what you model!  Soo, you create an object of type
"Products_Table" which contains methods to operate on the entire
table.  Then you create objects of types "Products" which contain
methods to operate on the objects.  But since your products can be
many different kinds, you don't "hard code" what kind of product they
are, you just make a generic object that contains generic functions.
If you wind up needing to do something special for a particular
product, *then* you create a subclass of product for that kind of
product that you can use for that.  Ie:  "Delicate_Product" might be a
subclass of "Product" that might have a special some special methods
for dealing with products of that type.  Something like "find" should
be a method of the table that returns an instance of your product.

So, your loop becomes something like this (pseudo code that looks like
c++?):

while(sData = Input.Read())
{
	MyProduct = new Product(sData); // object init's itself
	if(MyProduct.Validate())
	{
		MyProduct.Write(Table);
	}
	delete MyProduct;
}

Is there a way to upload more than one file or image at once?  It seems very
cumbersome.

thank you!

Hmm.. are you sure you are starting Zope as a priviliged user, like root?
Zope can only bind to port 80 if started as a priviliged user (it will not
run as a priviliged user, rather, it will, by default, switch to 'nobody').

The permission denied error is clear pointer in this direction.

Lynx does frames just fine. It lists them as hyperlinks. Just select the
second one, and you'll be amazed how much you can do with Lynx and Zope =)

This is because:

1/ MailHost doesn't integrate into the transaction mechanism all that well
(patches accepted =))

2/ Email is inherintly an unreliabale form of data transport.

Hi. How's Jim getting on with this? Apologies if I missed something

Hi everybody,

although this may have been discussed several times:

I added a multiple property to a class, but when I call the instance's
property sheet from the management interface, I get an Type Error,
whenever I did not chose anything from the selection box. That is of
course ok, because there is no property defined within the instance if I
did not select anything. (getProperty(id) fails on None)
How do I create an "empty selection"?

Thanks for your help

BTW: <dtml-call "REQUEST.set('x','[]')"> did not work.

He has checked in the fix - if you are tracking CVS you need to 
update lib/python/ZODB/TimeStamp.c and rebuild it. For those not
using CVS, I've attached a copy of the updated file to this email 
(but you'll still have to rebuild the extension for the change to 
take effect).

It is definitively not a good idea to rely on browser detection
for you pages. Especially if you dont already know how to do it.
Try to make your HTML-code not so special to let it work for all
browsers (you cant know how to handle the specific of all the
browsers available).
But, if you really cant live without it (please overthing it more
than twice!)
REQUEST['HTTP_USER_AGENT'] is your friend, together with various
string-operations.
Please note: you cant be sure if this field is set and tells you the
truth about the partcular user-agent.

Subject: [Zope] Syntax for getting property sheet
Message-ID: <m31z5mmy4y.fsf@wacko.pdx.net>

If I have a ZClass with a property sheet called 'Info', how can I get
access to the sheet when I DON'T have an instance of that ZClass to
work with.

Specifically, I want an ADD form for my ZClass that has an ID field
and a dynamically generated section containing all the properties from
'Info' all on ONE from.  I can't seem to figure out how to dynamically
generate the property section without an instance to work with.

Actually the guys at Spam inc. IT do model Spam cans (how about the lot 
numbers in case of botulism or something?) I believe the reference to 
Spam
was just an example though ;-)

More likely I would write a Class called "Table" that knows about 
accessing all 
relational database tables not just "Products" (see Data Adapters in 
Zope)

Would you have a different table for this?  This is a debatable topic -
if you don't have different attributes for your subclass then, it is 
argued,
you don't really need that subclass. Special methods for this can be 
done
as you propose or just tested for in one class.  The reason this is 
important
here (in this discussion) has to do with oo-relational mismatch or 
impedance.
When you are bringing back your objects from the database you are going 
to have
to know which object to "instantiate" (this term is used losely here). 
This means 
special handling for your queries. Or you can pay the pain by having 
two tables which
makes your queries for all objects harder. As you can see it isn't 
necessarily simple.

There are several ways actually --

This would translate to a "Stock" object with three attributes
as you have stated below -

Yes this is still olde kinderhook.

For me this method would be an instance method, each instance would 
have it called upon itself.

Actually you are correct. There will be an input program. You won't see 
much
difference between OO and your conventional database way (if you will 
allow me
to assign that term here). The reason is we haven't actually done 
anything
too significant yet.

Using my assumptions and examples from above I would have the Stock 
class
ask my table class to build a SQL query to do this

As above have the Stock Class have the table class find all "rows" which
meet this criteria then for each instance send updatePriceBy(2)
where the 2 is an argument and since it is positive the instance of 
stock
will add 2% to its own price

Here comes more spin though I'm afraid (sorry :-P)

Up til now I've left out alot of the mechanics.
The Table Object knows how to form SQL queries which gets you subsets
of your objects (not just rows of data) It in effect provides the code:

   product_1 = Stock(product_code="ABC",Description="Spluggifier", 
Price-"20.00")

only instead of product_1 it would be 'next_row' or 'this_row' 
(depending
on how you like to think of database cursors). Also somewhere there is 
a mapping between
the Table and the Class it represents. This allows the Table to become 
a Class,
the row to become an instance, and the columns to be attributes. These 
mappings
would be plugged into the above code also (i.e. product_code becomes 
attributes[1])

This mapping solution is a common pattern - IDL to Corba, DTD to XML in 
generic terms.
Here we start to see OO work. I defined my class and map it to 
different things
such as Corba or XML - now I can ship the object flattened as a string 
(or some other
form) and a reciever can inflate it back. This would be the user input 
form. This flattening has a special name in ZODB (as far as I can tell) 
it's "pickling"

Hope this doesn't add more head spin. There is much more to this story, 
we haven't
even talked about, such as foreign keys and how to map them to Objects. 
 

As far as modeling the data, I don't model a database, just the data, 
but it also
depends on if you are supporting a previously existing database or 
starting new.  I have done both and it is a black art. You have to 
support management, other departments etc without tipping the boat 
over, so you generally follow the flow. But for the most part you want 
to analyze the problem domain from an object point of view from the 
start. This gives you important insights to other parts of the problem 
such business processes and object interactions you didn't know about. 
OO is not just an elaborate ERD (Entity Relationship Diagram) But it is 
the most common place to start. This is just one way to do it, not 
necessarily the "Right" way, (if there is such a thing)

Hope this Helps

Other people answered your conversion question, I just wanted to point
out that the ':int' notation is meant for use in qualifying HTTP POSTED
data, like that coming from a form.  For example:

<form>
  <input name="bob:int">
</form>

This will cause ZPublisher to try and turn the value of this element
into an integer.  This is the only place the ':int' notation makes any
sense.  In your example, you have confused this notation with that of
the let tag.

Subject: [Zope] Property Sheet Question
Message-ID: <4.2.2.20000307143411.00b56800@saladin.aisys.com>

I'm defining a property sheet for a new ZClass object.  I want to define a 
property which is collection of items (in my current case it's strings, but 
conceptually it could be something else).  When a new instance is created 
(or edited), I want the user to be able to specify 0 or more items.  Is 
there a property type which supports this?  What, for example, are "lists" 
and "tokens" and how do you make use of them?  In the particular case that 
I'm working on, I want a user to be able to enter one or more e-mail 
addresses and one or more urls.  At some point I will want to iterate over 
the e-mail addresses, or iterate over the urls when I construct a view for 
this object.

Any tips or insights on this subject would be appreciated.

Thanks.

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Message-ID: <38C55EE7.36417628@digicool.com>

There is no standard rythem for manipulating the class without an
instance.  At least not that I know of.  It can be done, however,
because it can be done from the managment interface.  Anything that you
can do with clicks in a browser you can do with DTML, it's just in this
case your problem is necessarily complex because we never, ever,
considered your use case when we engineered ZClasses.  This is one of
the reasons why software can be dificult to use, because the engineers
did not KNOW in advance how you wanted to use it.

But you want to do this so I suggest you look at how the managment
interface traverses through the Control Panel and Products to manipulate
ZClasses. Using URL introspection, you should be able to deduce how to
do this.  I would help you but I honestly don't know how it would be
done myself.

I use IE5 on Win98 and NS4.7 on an old LinuxPPC box. No problems here with
Netscape running away though, I leave it running days at a time.

Netscape on NT/98 frequently runs into authentication problems with our Zope
install (using mod_proxy and ZServer) and sits there flickering the status
bar forever, whereas IE5 doesn't do that, it pops up the password dialog
when confused. IE does occasionally crash in the management screens (never
any other time), and I can't figure out why.

Subject: [Zope] manage_exportObject
Message-ID: <38C56A34.F9D9453B@globalcrossing.com>

Now I am desperate, this is the fourth posting and still only one reply.
Any thoughts no
matter how far fetched would be overwhelmingly appreciated.

Does anyone know how to export an object (Folder or such) from outside
of the Folder that contains the item to be exported without hard coding
the path. In other words I would like to be able to have a user
interface which would allow a person, with an export role, to be able to
enter a
list of fully qualified Items to be exported.

Consider:

FolderA
        FolderB
                ItemToExport

I can export ItemToExport from FolderA by calling:

<dtml-with "FolderA.FolderB">
        <dtml-call "manage_exportObject(id='ItemToExport')">
</dtml-with>




but I don't want the FolderA.FolderB to be hard coded. I would like it
to be a var that I pass into the method. Something like:

<dtml-with FullPath>

what should the syntax be. 

Thanks,

OK, but see you're trying to make Linux something it is not.  Linux is
not about marketing.  It is not about world domination.  We
specifically do not care about this :-)  Now, digicool is a company,
and they probably DO care about this.  Making Zope Free Software is a
great way for them -- and us -- to benefit.  So your comments should
be addressed at them if you want them to make the sale.  Not me, a
Linux hacker.

But see again, Free Software is not about marketing.  The name is
irrelevant to us.  Free Software is about what's *right* and what
*works*.  We leave the marketing to those that want to do it (such as
digital creations, or whomever else).  So again, write to digital
creations' marketing dept. :-)

have you figured out a way to move through the ZODB for a certain type of
object?  and then manipulate it in the way you need?  I'm having this same
concern from a project right now -- they are scared to put content in ZOPE
because if we move to another content manager- we may not be able to get the
data out (please point me to info). 

your secondary question is just as valid:  versioning lingo in zope is not
versioning as in source versioning but a 'temporary lock' on files.  things
look differently in/outside of versions.  thats versioning now.  how about
retaining 'versions' of a website (I think vignette does this) - so I can
call (if I had diskspace and *WANTED* to) my website and say, "what did the
frontpage look like last month?, last week?, two days ago?" <- anyone worked
with this, because this is what is typically referred to as 'versioning' (I
believe).

Thirded. I discussed starting somekind of Zope-XML SIG with Amos Latteier
and generally he's favorable to this, but how do we start? We need a mailing

Thanks.

What had me confused is that

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date())">
<dtml-var Currentdate>

and

<dtml-call "REQUEST.set('CurrentDate', ZopeTime().Date)">
<dtml-var Currentdate>

both display the same date string whereas I guess the latter should
display an error.  It only reports an error when I try to do something
else with the variable.

Hm, skilled developers do hack on Python! There's the Python people at
CRNI, there's Christian Tismer in Germany doing Stackless Python (which
offers interesting arcane features and a mild performance improvements),
there's the whole JPython group, there's John Skaller with his Vyper
project (a Python interpreter/compiler in Ocaml, one of the reasons
is more speed). Then there's the Python Types-SIG, which I urge you to
look at if you haven't already.

It is _less_ of a problem, but most Pythoneers are indeed interested in
speeding of the language. I haven't heard of zealots who want to hold
back speedups, as long as it doesn't do away with the power.

It'll be pretty difficult to make a beast like Zope exploit type-hints, though,
I think. By the way, the Types-SIG is working on type extensions to Python,
partially for performance (OPT), partially for better error checking (ERR)
and partially for better documentation (DOC). See:

http://www.python.org/sigs/types-sig/

And also see the new compiler SIG:

Type inference is not a simple thing to add to the language, though..

That's of course true. I heard Christian Tismer talk about making a 
register machine interpreter for Python, which could potentially speed
things up quite a bit. I shall ask him about this idea again sometime. :)

All true. Anyway, the only thing you're wrong about is that Pythoneers aren't
interested in improving performance. They are, but I grant you they're not
performance nuts like users of C or C++. :)

Ask Linus Torvalds. :) Anyway, Linux is what people do with it. Not what
people say about it.

I care about making Zope more popular, as there will be more Zope users,
more Zope hackers, and better free Zope support. More cool Zope goodies.
More Zope related jobs. I care about Zope marketing.

Even if you only care about Free software, you care about marketing it,
as you care about what's 'right', and therefore you want people to use
the right stuff; Free software. Right? :)

Alexander Staubo obviously was interested in Zope marketing. Why tell him
'we' don't do that, while some of us are definitely interested?
Free software is about people doing what they want. Let us do want they
want and don't speak for me. :) Thanks.

This is just a guess (I'm a Zope newbie too) but I believe

<dtml-return "['John\'s', 'Mary\'s']">

Will work.

In the second case, I guess <dtml-var CurrentDate> is recognizing that
CurrentDate is a reference to a function and calling it.

I understand, now, how that had you confused. Anyway, glad it's working!

These are what you want. In the case of tokens, it will separate each word
into a list element. A "lines" property separates each line into a list
element.

Tokens: 'foo bar baz' = ['foo', 'bar', 'baz']
Lines:
foo bar
bar
baz

Becomes: ['foo bar', 'bar', 'baz']

This should work fine using standard <dtml-in>s, since tokens and lines are
sequences.

The kernel internals of Linux use a 32 bit off_t, hence discussion of
large file support in the next kernel release.

I'm not seeing an x86 problem at all:

lukasiewicz$ uname -sp
NetBSD i386
lukasiewicz$ ls -l huge
-rw-r--r--  1 tsarna  users  17592186044415 Mar  7 12:41 huge

Granted, that's a sparse file (I can't afford that much disk space :^),
but it demonstrates that file offsets are not a problem.  As mentioned,
NetBSD's off_t has been a 64 bit type for about 6 years now, even on
i386 (and evey other platform).  In fact, off_t was made 64 bit in 1994,
and NetBSD/alpha didn't exist until 1995, so it was done before there
were any native 64 bit platforms supported.  :-)

However, it turns out that for Zope use, at least with FileStorage,
there is a problem, which turns out to be even an x86 issue but a silly
ANSI C spec issue.  Unfortunaly Python large file support is broken on
(32-bit CPU) NetBSD as a result -- I had to make that sparse file with a
little C program.  Now, you could have a more than 4G BerkeleyStorage
Zope system, since the file handling isn't done at the Python level in
that case, but FileStorage won't work until I can work around the Python
problem (or until NetBSD 1.5, which will fix it in a different way). 

But at least it's the kind of thing that could be hacked around in an
application by one guy in a day, rather than taking drastic kernel
and libc changes :-)

Packing does not modify your existing database file until it completely
succeeds.  During the pack, packed data is written to a temporary file
and your main file is just read from.

FYI, you are searching for the union of two search terms, 'ZODB' and
'troubleshooting' which is why you got more for the second query than
for the first.  To explicitly get an intersection, say 'ZODB AND
troubleshooting'.

That bring you back a much smaller number (0).

One place to start might be to join the Python XML SIG. It has a high
S/N and most of the discussion is probably relevant to the Zope XML
effort.

It would provide the benefit of knowing what's currently available from
AMK, Four Thought, etc., which might be reusable for Zope.

Four Thought's 4DOM, 4XSLT, 4XPath are getting pretty mature, with 4ODS
and 4XLink in the wings.

Additionally, if you haven't the bandwidth (I certainly don't) to
follow the xml-dev newsgroup, the XML SIG gives you a filtered view of
all the mighty standards power struggles going on as we speak in the XML
world, so you can have some perspective on the right time to jump on the
Schema train and so forth.

Thanks.
We will eventually be looking into optimisations for the list command,
to
reduce the depth of braches traversed. If any UW IMAP users can confirm
which flags represent what in that context, that would be helpful. Then
we
could avoid listing them.

Yes, I did get the following response from Drew:

--- snip ---

The easiest way to make changes to all of your SQL methods would be to
export your entire Data.fs into XML format -- then use your magic       
text editing software tools.

With respect to version control and configuration management, I have
used the same XML export format and checked this into CVS. Of course,         
I feel that XML is human readable... YMMV.

--- snip ---

I agree with this basically, and I can see this as a partial
solution.  Basically, if you were using this in production, you would
want to schedule a script to automatically pull out the XML export
from your site say, once a day, and check it into CVS.  Depending on
your needs and your ambition, you could probably go so far as to go
into particular folders and pull out peices of the site individually
and check those in seperately, that way you could look at "Show me all
objects that have changed since April 10th" or whatever via CVS.  This
would also allow you to rollback to a previous version (ala Software
Configuration Management type stuff) by checking out all peices to a
system from CVS and then importing them back into Zope.  Kinda a
hassle compared to how CVS automates other development environments,
but then, other development environments aren't quite web RADs
either.  At least you CAN export and import the data as XML.  A
similar situation arises with tools like Delphi etc where your forms
are binary files and you can't make global changes to them except via
point and drool^H^H^H^H^Hclick.

Note: I refer to scripting exporting.  At this time, there's no tool I
know of to do this.  You would need to do this yourself.  SO... if
there's anyone out there who is a wiz with the ZODB that could MAKE a
tool to pull this stuff out.  I'd appreciate it.  If it was me, I'd
just script something to pull it through the web interface, but a
non-web oriented, just run on the ZODB tool would be better.

Message-ID: <200003080133.UAA14797@saltmine.radix.net>

Ok, I've gotten pretty far with Zope this time.  But (of course), I've
got a bunch of questions.  Starting with...

1)  What is the algorithm for determining which method to call?  The
    DTML documentation says

  "attributes, including inherited and
   acquired attributes, of the client passed 
   in the call to the document template are searched"

   But in what order?   There can be an index_html in the class, in a parent
   class, or somewhere up the acquisition tree.  Which takes precedence?
   Does the product that a ZClass have anything to do with the search?
   What about Z-Super-Classes?  Inquiring minds want to know.

1a) Why can't I have a method in a ZClass, but then override it in
   the instance?  I.E. (Gaak, it has been a while since I've had to
   even think about C++) virtual methods?  (Or have I got that wrong).

2) It seems that the examples require the user to generate forms by
   hand, which seems unnecessary.  For example, (after a protracted
   struggle with the underlying python code) I wrote a method that would
   create an html table for any query, ripping the column names and data
   out of the result object.

   2.1) Shouldn't this be a standard part of Zope?
   2.2) If so, do you want this code?
   2.2) Likewise for property edit forms.  I did find some DTML that
        would do this, but shouldn't this be standard.

3) Anyone want to help me whip snmpy into shape and create soem
   nice Zope classes for accessing SNMP variables and tables in routers
   and such?  

Enough for now...

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time.  I get the following log

I would have to research this to give a precise answer. Basically, it all
depends on the current contents of the namespace stack. Generally, this
will search REQUEST first. Next, we look to the object containing the
method being rendered. Then, the object containing that object, etc.
Whenever a ZClass is queried for an attribute and doesn't have it, it
looks to its parent(s).

I made this mistake when first working with ZClasses, too. If you think
about it a little, you'll realize that, virtual or not, you cannot
customize an OBJECT in C++, only a CLASS. i.e.:

---
class A
{
public:
  int x;

public:
  A() { x = 0; }
};

class B : public A
{
public:
  int y;

public:
  B() { y = 0; }
};

A* objectA = new A();
B* objectB = new B();

objectA->x = 1; // Valid
objectB->y = 2; // Valid
objectA->y = 2; // Invalid, because class A has no such attribute.
objectB->z = 3; // Invalid, because class B has no such attribute.
---

If you want to customize an object (instance), you have to extend its
class, first.

In Python, this is not (really) true. Any old object is a dictionary, so
yuo can add attributes to it on the fly. Thus, the question, how can we do
this with ZClasses?

I wrote a base class that overloads ObjectManager's _checkId method to
allow instances of a ZClass to be customized. It looks like this:

---
from OFS.ObjectManager import bad_id

class Overridable:
    def _checkId(self, id, allow_dup = 0):
        if not id:
            raise 'Bad Request', 'No id was specified'

        if bad_id(id) != -1:
            raise 'Bad Request', (
                'The id %s contains characters illegal in URLs' % id)

        if id[0] == '_':
            raise 'Bad Request', (
                'The id %s is invalid - it begins with an underscore' %
id)

        if not allow_dup:
            if hasattr(self, 'aq_base'):
                self = self.aq_base
            if self.__dict__.has_key(id):
                raise 'Bad Request', (
                    'The id %s is invalid - it is already in use' % id)
---

This is not foolproof (it allows you to override TOO much, i.e. you can
create a method with the same name as a property), but it shows the idea.
I just subclass my ZClasses from this class, and I can customize each
instance individually.

Thanks a lot Ty for the detailed reply. Mostly for clarifying a few of
the stuff you were talking about at IPC. Seems to me that at least some of
the major components of Zope should be designed in this manner, but on the
other hand it is only after one codes a few specific situations that the
general pattern emerges.

Subject: [Zope] index_html for root
Message-ID: <001201bf88c0$8ad24e40$770da8c0@bbs>

The attached file is intended to replace the current architecture of header
body footer of current zope default index_html.

Together there will be some attributes which can be used to modify its
behaviors :

wap - when defined, set the content-type in RESPONSE accordingly according
to Ducan's WAP howto. and sent out the <wml></wml> tag.

xml - when defined, set the content-type to xml/plaintext and the xml header

frame - when defined, prevent sent out the body tag

Only one of the above can be set. I still got problem with acquisition: if
one of these is set in a higher lever, then all lowerlevel see it. Are there
any easy way to set them off?

doctype - when defined, should contain the correct doctype string: currently
the following doctype is available:

    html4.0
    htmlstrict4.0
    htmltransistional4.0
    htmlstrict4.01
    htmltransitional4.01
    htmlframe4.0
    htmlframe4.01
    xml1.0
    xhtml1.0

The following is defined inside the index_html:

dtml-head - the content of the <head></head> section
dtml-headers - the content of contructs before the main body: This should
not left any tag open.
dtml-footers - the closing contents of the main body. There should not
assume any opening tags.

index_htm - the main content. a frameset statement if frame is defined. If
the main content contains a table, then the main table is defined here, the
parts in the table can then be dtml-var. A index1 index2   .... or indexr1c1
index r1c2 .... naming convention is suggested.

I strongly suggest convert the current zope sites to adapt to this style
through much works shall be needed.

Further work would be in the dtm-head: Recently I will suggest to adapt the
W3C core styles : http://www.w3.org/StyleSheets/Core/Overview

All suggestion and comments are welcome.

Message-ID: <NDBBLBELNHAPHBBCOIFDGEHLCBAA.ewalstad@energywright.com>

Hi David and the rest of the group,

Can you believe I am still battling this MySQLDA installation!?  ARGH!

I hope you can help me out here:

According to the HOWTO by alanpog, I've
1. Downloaded MySQLDA 1.1.3
2. Expanded it into my top level Zope Directory (/usr/local/Zope) Note that
I did not do any installation here, just expanded it into this directory.
3. Downloaded MySQLdb v0.1.2
4. Expanded MySQLdb into /usr/local/Zope/lib/python/Products
4a. Modified the Setup.in file so that the one uncommented line is:
    _mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt
    As you mentioned, these point to where my MySQL libraries are.
4b. According to the README file, ran 'python build.py'
This is where I am stuck.  The build.py script crunches along then bombs
with the following error:

Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I checked and this file is in my /usr/local/lib/mysql directory.  It is a
link to libmysqlclient.so.6.0.0.  Both files are there; owner=root,
group=root.

I'm hoping this is a simple fix ;^)

Any idea's would be greatly appreciated!

Eric.

>Is there a HOW-TO or other documentation that shows how to set up a login

>advance for any help/pointers provided.

I don't know if there is a how-to but the way I do this is very
simple. I have a simple form with only a submit button with name login
(it appears on a sidebar of the web site).  When it is clicked it
posts to the current URL.

<dtml-if isRegistered>
You are 
<dtml-in "AUTHENTICATED_USER.getRoles()">
<dtml-var sequence-item> 
</dtml-in>
<b><dtml-var "AUTHENTICATED_USER.getUserName()"></b>
<dtml-else>
<FORM ACTION="<dtml-var baseURL>" METHOD="POST">
<INPUT NAME="logon" TYPE="SUBMIT" VALUE="Logon">
</form>
</dtml-if>

In the start of every page I call a method to check for 'login' in the
REQUEST variable. If it exists I calls or references an empty method
which anonymous users have no rights to but which authenticated users
do have access to (with ID login in this example.

<dtml-if "REQUEST.has_key('logon')"><dtml-var logon></dtml-if>
<dtml-call "REQUEST.set('isRegistered',AUTHENTICATED_USER.has_role(['Staff','Student','Manager']))">

Zope will therefore invoke the authentication mechanism which means
the browser will ask for a login a password as usual. From there on
the user will have been authenticated and you can check their name and
what role(s) they have in the current context. 

As you can see once with the code given here the user has logged in
instead of a login button they will see a message giving their
username and global role(s).

Hope this helps.

I am making a new head zope index_html file, I think it is now about time to
make use of the HTTP_ACCEPT_LANGUAGE which is sent by the browser to
indicate the perferred language.

The variable is a string like:

lang1, lang2;q=p1,lang3;q=p2....

while lang1, lang2, lang3 is the perferenced languages.

I have think of the following ways to make such brenches in zope:

1. by setting the lang variable in the REQUEST
2. by transfer to the brench of lang/
3. brench calls of index_lang

What will be the perferred way to make such a brench? I want to hear from
all.

In building the brench code : I have come up with the code:

<dtml-in "_.string.split(HTTP_ACCEPT_LANGUAGE, ',')">
   .....do thing according to sequence-item
</dtml-in>

but on the second argument, the sequence-item may contain ;q=0.5 which need
to be trancated. How can I trancated that in dtml?

It's quite nice being able to edit the site using Lynx,
but you cannot create new objects as the 'Add' option
box uses Javascript. Because it's listed as DISABLED,
Lynx won't let you pick a type before clicking on Add.

move to the new style <dtml- from <--# tags.

I'm also waiting for someone to write the "dtml-method beautifier".  :)

I played around with nedit's syntax-hiliting so it recognizes dtml as
opposed to regular html.  Not perfect, but better than nothing.  Plus I
improved the python mode a bit.  If any one wants it email me.

Nope.  There may be some standard python library module that I don't
know about, however.  Otherwise, you will have to write your own.

The first two follow standard python rules, first instance attributes,
then shared instance (class) attributes, then any base class
attributes.  THEN acquisition.

No.

Same rules.  First the instance of the ZClass attributes, then shared
instance (ZClass) attributes, then any base (Z)Class attributes.  THEN
Acquisition.

I think your confused but I'm not sure.  If your ZClass is a container
(subclasses ObjectManager) then instances of that class can contain
sub-objects (attributes) with names that are managable by the Zope
managment interface.  The managment interface will NOT however let you
create a sub-object in that container that conflicts with the name of an
existing attribute *including shared instance attributes like methods of
YOUR ZClass*.  Methods of a ZClass may look like sub-objects in a
container instance, but that are not, they are shared attributes of a
class, and all instances of that class will share those attributes. 
Now, this is a limitation/feature of the managment interface, it is not
a limitation of python.  If you want to assign an attribute to an
instance in python that has the same name as a shared instance
attribute, then that instance attribute will override the shared
instance attribute.

Ok.  You're talking about SQL Methods?

If you're talking about SQL Methods or other objects that implement the
Zope Search Inteface then it is allready a standard part of Zope.

You should look at what is there first and tell us how to improve it.

The managment interface obviously builds the property view dynamicly, so
something like this is in Zope.  Whether or not it is useful to others
is unknown to me.

Right, this is certainly a good place to go to as well. But Zope has its
own rather different requirements, and I think we need a seperate place
to discuss adapting all these technologies so they'll work with Zope -- 
the people in the Python XML-SIG might not care about Zope.

Also, the Zope XML list should also be the place where people ask *questions*
on using Zope with XML; this way we learn more about what people want and
what problems they may be having. And that way we can improve Zope's 
XML support. The Python XML-SIG wouldn't be the right place for that.

Okay, I was considering joining that SIG anyway, but I don't think it's
enough for developing Zope's XML support.

I would say that I specifically do care about this. As a freelance 
developer I want there to be good recognition of Zope in the market place. 
It is all about recognition. I was extolling the virtues of Zope to the IT 
Director at a client and he said 'So why haven't I heard of Zope ?'. My 
answer, that it was all very new and on the verge of success probably did 
not convince him. (Of course it is all very new and it is on the verge of 
success ).

If I say Linux, Perl or C then management are usually quite happy. These 
are recognised names - but nobody owns them. SO it is possible for free 
software to be successful in the sense that they are as well recognised as 
commercial products (which have huge budgets behind them).

Some management (perhaps most) will prefer to buy a "fully supported" 
product from a major player. We don't need to take on that kind of 
marketing head on. Rather we can present Zope and Python as tools to do a 
job, not strategic decisions to be made by management. However it is 
reasonable for management to ask "Will Zope be around in three years" - 
"can we de-Zope if we have to" - "Who owns Zope" "Who uses Zope". Managers 
are not likely to take a "risk" on a product. At the moment they usually 
feel happy that Linux, C and Perl are going to be around in three years time.

If Zope is to succeed it will be because of its capabilities as a product - 
because it installs out of the box in six minutes, while the Microsoft 
equivalent takes 5 hours. Because 60 minutes after downloading it you can 
be running a web page which interrogates your legacy databases (which is 
what happened to me).

We know about the documentation issue, which is hopefully being sorted.

I feel there is also an issue with the product itself. Zope seems to work 
on two levels - you have a very high-level part - I'm thinking of the 
security model, the SQL methods and the Z Search interface, the drop-in 
products like SquishDot etc. These set Zope apart from other technologies 
which people might use (PHP/ASP etc).

You also have a low-level  part (External methods etc). Because Zope has 
the high level part it encourages the thought that there is not much 
'programming' needed to develop a Zope site. But sooner or later you are 
going to hit a wall - for example questions you see asked on this list such 
as "how do I assign a value to a variable". Well the answer is ...

<dtml-call expr="REQUEST.set('abc_search', strip_abc(abc_text))">

... a string of gobbledygook. (So what does the dtml-let tag do is the 
obvious question that springs to mind.)

It is great that Zope has the low level stuff but I feel that work needs to 
be done

1) To analyse actual usage of Zope to see what features are being used and 
which areas of usage cause concern/difficulty
2) To Implement high level dtml tags to implement them.

I've stuck my neck out here - feel free to chop it off.

How do I call the stored procedures written in Oracle from
"Add a SQL Method" interface, especially when there are OUT parameters
returned from stored procedures? I have read the DCOracle mini how-to
but there seems to be a missing step ahead.

Assume the scenario:

Oracle Procedure: myProc(para1 IN  VARCHAR2,

What should I put in the "Arguments" box and "Query template" box? 
And how do I retrieve the returned arguments in the following dtml
document/methods? Thanks a lot!

Yes, I care too. And for the exact same reasons. The more popular Zope becomes,

Yes. Alexander has brought up a very (IMO) relevant issue. It is in the
interest of the entire community to make Zope well known and I feel marketing
should not be left just for DC to take care of.

I see a number of articles/sites about 'app servers' which don't mention Zope
but mention others (including some mickey mouse servers I've never heard of).
Eg: http://serverwatch.internet.com/appservers.html
Why? Maybe Zope isn't talked about at all outside some circles?

Altavista shows about 1058 pages linking to zope.org (compare php.net:12,000 ;
apache.org:60,000). Why?

If nobody does anything, this will take time to change. If we want this to
change faster, all of us have to actively market Zope. This involves talking
about in appropriate newsgrousps, putting up zope webpages,
making Zope easier to learn and use, adding flashy features etc.
All this can make a whole lot of difference.

Still it would be sensible to do it by splitting the database file (say at
1M boundaries rather than supporting some obscure non-standard system calls 
that only few platforms support. Probably also one-day hack by someone 
who knows where to start digging.

At least this is how it was solved for PostgreSQL .

Subject: [Zope] getting object reference from an id string?
Message-ID: <001001bf88f9$4b84eca0$a1ac8ec6@hikari.anu.edu.au>

Say one has an object reference and knows the
string id of a child node.  From this info, we
want an object reference to the named child.

I'd like someone to prove me wrong that there
is not a one-liner to accomplish this seemingly
trivial task.  I've had to resort to (off the
top of my head) code like:

<dtml-in "objectValues(['child meta-type'])">
   <dtml-with sequence-item>
      <dtml-if "id == desired_id">
          <dtml-call "REQUEST.set('desired_ref',_['sequence-item'])">
      </dtml-if>
   </dtml-with>
</dtml-in>

I'm really looking for a solution that doesn't
require looping.  Since Zope enforces unique id's
at a given level, the name should be sufficient
to resolve the child object.

Darran.

just use 'reverse'

   If you remember, it wasn't done in a day. There was a long period of
bugs, esp. bugs in VACUUM.
   I wouldn't buy your idea of easy splitting Data.fs. Exactly like with
the VACUUM, packing Data.fs would be complex task if the data will be

The claim of "a days hacking" was meant as an ironic counterclaim to it being 
a day's job on *BSD

I would suggest it by implementing a file-like HugeSplitFile class and 
using that to hide all the splitting from all other layers. 

If we could implement it in python then it would be perhaps a 1-hour job, 
leaving the rest of the day for fixing up the parts of zope interfacing 
with it ;)

It would probably consist mostly of adding long() to some initialisation 
functions.

   This is a record object. You should use:

On the other hand, if you tell the user up front that HTML tags are not
allowed, you can simply html_quote the text.  That will prevent any tags
from rendering, and prevent normal uses of '<>&' characters from breaking
anything.

Subject: [Zope] Performance and Concurrency
Message-ID: <200003081355.IAA06034@saltmine.radix.net>

I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute).

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

to take the html and turn it into plaintext.
Pop it into an external method something like the following, and it should
do the trick:

---html2msg.py

from popen2 import popen2
def html2msg(htmlstring):
  try:

    (r, w) = popen2('/usr/local/bin/w3m -dump -S -cols 70 -T "text/html"')
 
    w.write(htmlstring)
    w.close()
  
    s = r.read()
    r.close()

    return s
    
  except:
  
    return 'Error converting article to plaintext.'

It's an ugly hack, and you lose things like <br> and <p>, so you may want to
replace \n with <br> afterwards. It does, however, do a brilliant job
layout-wise: tables and lists remain fairly well formatted, for example.

Sorry, I wasn't clear.  What I was looking for was a method to get,
for example, an html table out of what an ZSQL method returns.  I
had to look at the code under lib/python/Shared/DC/ZRDB to figure
out that calling a ZSQL Method returns a Results object, and then
look at the results object to see that it has methods like names(),
data_dictionary() and tuples().  Then I could write a loop like...

    <dtml-with "Your-query-method(parameter=value, parameter=value)">
    <table border=1>
      <tr>
        <dtml-in "names()">
          <th><dtml-var sequence-item capitalize spacify></th>
        </dtml-in>
      </tr>
      <dtml-in "tuples()">
      <tr>
        <dtml-in sequence-item>
    	<td><dtml-var sequence-item></td>
        </dtml-in>
      </tr>
      </dtml-in>
    </table>
    </dtml-with>

My point, I guess, is to suggest that this should be a built-in method
in a ZSQL query.   Unfortunately this would also hard-code the
appearance of the table unless it had lots of options.

I'm probably missing something.

I did find code that kind of did this in the manage_test method in the
ZRDB/DA.py file, but when called returns manage_tabs, and also access
some non-dtml-accessible functions like result._serachable_result_columns().

I'm sure I'm missing something, but this doesn't seem accessible from DTML.

Once again, there is code to render property table forms, but it is 
buried inside lib/python/OFS/properties.dtml.  Once again, it seems
as if a standard method to generate a form for editing properties
would simplify creating applications by eliminating the need to
type in, by hand, the required forms.

I've seen a couple of pieces of code, both in the mailing list and
on zope.org to do this.  

The overall goal is to make it easier for beginners to whip up an
application without having to know too much about html forms and
formatting.  Plus to make the system easier to maintain by not having
redundant information (i.e. in the property sheet or query, and also
in the DTML that renders it).

Thanks for your time...

I forgot to try that (I tried using alternative quote characters and that

In my ongoing efforts to gain a bit of recognition for the capacity of
Zope, Python,  and all things Open Source, it looks to me as if Marketing
Matters, regardless of my wishes. Even if, to me, the validity of Zope /
Python is "obvious", it is not so clear to others, and especially others
who make decisions about tool selection. 

At some point, if Zope / Python is to find a place in the larger world,
these folks must be convinced. There may be a more palatable word, call it
"education", "concsiousness raising", or some other more trendy phrase.
Still, you can get the gist from the words, "selling", "marketing", or even
"hype".

Check out some of the articles by the folks at Bynari Associates (any
search engine will get you there). You can see the need for marketing of
Linux and Open Source tools in their daily business. In fact, the articles
themselves are a form of marketing, gaining name recognition for Bynari
(see, it works!) in the Open Source community, while sharing the benefit of
their "real world" experiences of implementing "Linux" for paying clients. 

In short, the line between the coder and the customer relationship doesn't
look quite so distinct from here.

Later,
Jerry S.

Message-ID: <3.0.1.32.20000308102356.0068b264@bizux.net>

I am new to Zope but I am very appreciative of the How-To's and Guides that
have been produced by those that are more experienced than I in the use of
Zope. 

I am currently working on intranet for the company I work for, and am
having problems creating an instance of a ZClass, that I created, (DCTask,
which is actually the product, DCTaskClass is the ZClass)through the a
public interface (form that requires the entry of information that will be
added to the instance in the form of properties, such as the description of
the task and which department it is created for).

The form that is used to submit a creation action resides in a created
folder (http://diis/tasks/generator) and therefore does not reside in the
folder where the DCTaskClass_add method resides. I think that my main
problem, though I could be wrong, is that I haven't found a way to access
the _add method from the /task/generator folder through the use of the
<FORM ACTION="...">. I believe that once I have can access that file
through the form action and have the ability to send all of the relivant
information I will be able to create instances through the use of the
public interface (ie. the form)

Any help will most appreciated.

Best regards,

If you have a programmer and a web designer around it's possible to 
seperate the two tasks quite well, though, in my experience. Likewise a
situation with a programmer and a content manager, which is the situation
I'm in right now.

Still, both the web designer and the content manager want to know more
about Zope, and this does throw them off into the deep end (Python,
DTML, object oriented programming, etc).

I won't chop it off; you're right. Though I would say a simpler DTML
is only half of the story; the other half of the story is already there --
people _can_ use drop-in components. It's just that we need more and
better drop-in components (with possibly a nicer interface, ala Zope PTK
and/or Zope Mozilla).

Still, a simple variety of DTML would be nice. Currently you can
successfully use a subset of DTML, which almost has no arcaneness but
is still very powerful. PythonMethods will help even more there. Still,
DTML allows too much, so it's too easy to move into the arcane domain. Also
some of its powerful features have the side effect that some of the simple
features look too complex.

So perhaps we should create a seperate language, based on the subset,
with simplified syntax, which _doesn't_ allow fancy stuff. The fancy
stuff would be in DTML-methods or PythonMethods of some kind. Perhaps 
even the HTML would be in seperate methods. Perhaps some XML-ish Zope
glue language, like this:

<zopeglue>
<var object="header"/>

<assign name="age" object="get_age"/>
<var object="show_age_intro" arguments="age"/>

<var object="layout.table_header"/>
<in object="get_above_age" arguments="age">
<var object="myrecord" arguments="in_item"/>
</in>
<var object="layout.table_footer"/>

<assign name="age" object="getage">
<var object="footer"/>
</zopeglue>

And then some IDE that allows you to easily create all objects you
refer to here. Perhaps something wiki-like; any object name that you refer
to in the glue that can't be found will be presented in a list after you
edit the glue, and you can create objects for it then.

Ideas, ideas, now for some time. :)

Martijn

I would recommend taking a look at how the management interface does things.
(Just do a View Source in the Zope management frame that has the pull down
menu listing the different things you can add).

In KM|Net News, I made the incoming article form post to a DTML method
(AddArticle) that basically follows the steps in the "Adding ZClass
Instances Programmatically" how to.

http://www.zope.org/Members/tazzzzz/addZClasses

I haven't tested this, but posting your form to:

"manage_addProduct/YourProductName/YourZClass_add"

may do the trick, assuming your form is being called from the Folder where
you want the new instance created. Otherwise, you should do something like:

"/FolderForNewInstance/manage_addProduct/YourProductName/YourZClass_add"

The new scheduled DTMLMethod product, ZScheduler, can do that. Just schedule
the method for "now". Only works with DTMLMethod's but they can call any
other kind of method. The product is in alpha stages right now, so I
wouldn't use it for a production environment just yet, but I would
appreciate knowing whether it's useful for your application.

Friends of Zope,

My  Z2.log file entries which are in the  /var/Z2.log are inconsistent with the actual system time. 
The Z2.log file shows
123.123.123.123 [08/Mar/2000:16:49:40-0700]

The actual system time is  8:49 pacific time.
NT 4.0 show   (GMT-0800 UTC)  Pacific time (US and Canada);Tijuana
It and is set to automatically adjust for daylight saving time.  

I have a NT 4.0 windoze  workstation machine that is running Zope latest version 2.1.4. and of course python 1.5.2.
  
Is there a script file that needs adjusting to make the file log correctly?  I know that -700 is UTC is Mountain Standard Time.  Do Zope programmers like the warm southern climate better than the cold  climates?  In short can this "default" be changed.

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

Subject: [Zope] Setting title in an external method
Message-ID: <20000308121007.A561@cnri.reston.va.us>

Hi all --

A common idiom around here is to use an external method to process a
form and, if an error that the user can't fix occurs -- eg. you can't
view such-and-such an object because it doesn't exist, or you don't have
privileges -- use "return" to show them the contents of a DTML method
that explains the problem.

Here's a simple example:

    def my_xm (self, REQUEST=None, RESPONSE=None):
        # ... churn away, processing the form ...
        return self.my_dtml (self, REQUEST, RESPONSE)

Here's the source for the "my_dtml" DTML method:

    <dtml-var standard_html_header>
    title: <b><dtml-var title></b><br>
    document_title: <b><dtml-var document_title></b>
    <p>
    This is the <dtml-var document_id> Document 
    in the <dtml-var title_and_id> Folder.
    </p>
    <dtml-var standard_html_footer>

Both "my_xm" and "my_dtml" are in the root directory of an almost-fresh
Zope 2.1.4 installation.

The problem is that the "title" when I call "my_xm" (ie. the "Title:"
HTTP header and "<TITLE>" HTML tag) is just "Zope", which I presume is
the title *of the folder* containing the external method.  Yuck.  I want
the form result to have a title of its own, eg. "Error Viewing
Blah-blah".

What's the best way to do this?  Possibilities that occur to me:

  * redirect to the error-reporting DTML Method instead (but I like
    to keep the number of redirects to a minimum)
  * use a DTML Document instead of a Method (not sure if this will
    work, and sometimes I really do want it to be a method -- eg.
    it might be called from within a larger Document in some context)
  * set some magical attribute of 'self' or 'RESPONSE' in the external
    method; I tried "RESPONSE.setHeader ('Title', 'My Title')", but
    that didn't work

Any other ideas?  Thanks --

        Greg

This is the code that I have for adding the adding ID of the instance of
the class (it provides a random ID or at least generates on)

<dtml-call "REQUEST.set('id',_.random.random()*10000)">
<dtml-call "REQUEST.set('id',_.str(_.int(id)))">

I copied (and modifyed slightly) this from the How-To: AutoGenerate Random

Try htmllib.

The following bit of python will strip all formatting from some HTML. It 
replaces all anchors with footnote style references and images with 
their alt text. If you want something a bit fancier you could add 
methods to the MyParser class to pass through particular tags (see 
the commented out methods as an example). It shouldn't be too hard 
to wrap something like this up in an external method (as presented it 
is a complete runnable program that retrieves a URL and displays 
the text).

--------- File strip.py --------------
# Strip all HTML formatting.
import sys,formatter,StringIO,htmllib,string
from urllib import urlretrieve,urlcleanup

class MyParser(htmllib.HTMLParser):
    def __init__(self):
        self.bodytext = StringIO.StringIO()
        writer = formatter.DumbWriter(self.bodytext)
        htmllib.HTMLParser.__init__(self,
            formatter.AbstractFormatter(writer))

    def gettext(self):
        return self.bodytext.getvalue()

# Uncomment these to pass through bold tags.
#    def start_b(self, attrs):
#       self.formatter.add_flowing_data('<b>')
#
#    def end_b(self):
#        self.formatter.add_flowing_data('</b>')

def GetPage(url):
    try:
        fn, h = urlretrieve(url)
        text = open(fn, "r").read()
    finally:
        urlcleanup()
    return text

if __name__=='__main__':
    data = GetPage(sys.argv[1])
    p = MyParser()
    p.feed(data)
    p.close()
    text = string.replace(p.gettext(), '\xa0', ' ')
    print text
    anchors = p.anchorlist
    for i in range(len(anchors)):
        print "[%d]: %s" % (i+1, anchors[i])
--------- end of strip.py --------------

Subject: [Zope] Object Manager and Folder
Message-ID: <E12SkGf-00074X-00@home.delysid.org>

Hi.

I am quite new to Zope and currently try to create a BookClass ZClass Product.
I came across several issues where you probably can give me some useful tips:

1. What is the difference between inheriting rom Object Manager and/or Folder.

2. My product will include Cover Images of the books. (a small and a large one).
Whats the best way to implement this? I thought about creating emtpy images (smallcover and largecover),
but I dont know how to ask the Objects if they contain something.
Or should I just add the Images in my BookClass Instance programmatically?

3. Wasn't their any web-client product for Zope so that I could retrieve content from the web directory and import it in Objects (like a Image) without having
to upload it manually?

And the last one:
Is their any special reason why FTP access doesnt work in the /Control_Panel/Products folder?
All methods are empty their. I work with Emacs and ange-ftp is quite
a good method to access content of Zope Objects.

Besides, if I change the content of a Object through the web interface,
Zope seems to convert < > and " chars into &lt; &gt; &quot;
I understand why, but is this really necessary. It seems as if nearly all
textmode browsers (as lynx and emacs/w3) dont care about converting the entities back tto their corresponding characters.

Thanks in advance,
               Mario <mlang@delysid.org>

If you can figure out improvements on how to configure UW IMAP for
interoperation with WorldPilot that would be great. We're currently
lacking 
a UW IMAP server with a reasonable amount of data on it for looking into
the
issues.
I'm putting in a parameter to control the LIST call, I think that should 
reduce the load for the large part of the users, but we're open for any
further
adaptions.

Ryan

I am hoping to add some performance benchmarks, quotes, etc... In other

Message-ID: <OFA5CFA31F.A45A80B0-ON8525689C.006234C6@ssga.ssb.com>

I just installed Zope (on NT) and would like to have reasonable
backup/recovery options.  One way to do this is to just make a copy of the
data.fs file in the var directory, but I'm concerned that this file may not
be in a consistent state when it gets copied somewhere.  Should I worry
about this?

I'm thinking it would be better to eliminate this file in favor of an
Oracle or Sybase database (I have access to both).  Can I do this?  If it
is possible, would I want to do it?  If I should want to do it, how do I do
it?  I've spent a few hours searching the documentation, but this has only
convinced me that it may be possible -- I've been unable to find a
definitive answer.

Ok that seems to work because I am getting other errors and I think this
task is a little advance for a zope infant like myself. Now, this line is
causing me problems (this happened after I called entered the hidden field):

<dtml-call "REQUEST.set('id',_.str(_.int(id)))">

The error it gave me was:

Error Type: ValueError
Error Value: invalid literal for int(): generator

It seems to be refering to the "(.int(id)))" of the above code.

Dave & Chris,
Thanks for replying.
I'm running Caldera OpenLinux 2.3.  I chose it because I heard that it had
one of the smoothest installations.  I am only a few months into Linux; I'm
transitioning over from the Dark Side (Microsoft).  Heehee.

Here's my best guess at what's going wrong with the MySQLDA/db installation.
I think it is related to access rights or locations to the
libmysqlclient.so.6 file.  When I run build.py, I can see the script
accessing the MySQL library folder (in my case: /usr/local/lib/mysql)  This
is the path the MySQL 'make install' script displayed when it was done
installing MySQL.  I checked, and the library files are there.  Anyway, I
can see the build.py script working some of its magic within this folder, so
I feel confident that the paths in the Setup.in file are correct.  However,
it is crashing when it tries to "from _mysql inport *".  I am not (yet) a
Python programmer, so I don't understand the implications of this import.
I'll reprint the error message I received for anyone else that reads this:
Traceback (innermost last):
  File "build.py", line 14, in ?
    import MySQLdb
  File "MySQLdb.py", line 19, in ?
    from _mysql inport *
ImportError: libmysqlclient.so.6: cannot open shared object file: no such
file or directory"

I like your idea of making a link to the MySQL library file
(libmysqlclient.so.6).  I know this is a stupid question, but if I run:
ln  /usr/local/include/mysql libmysqlclient.so.6
what will the link be called, and where will it be located?  How will this
help the build.py script?

Thanks again for your input!


Chris,
This seems to be pretty common which makes me feel, well, not alone...

Thanks for the note and I'll keep you updated on my progress.

I reinstalled linux (probably didn't need to but I did)  I used an older

# ln  /usr/local/include/mysql libmysqlclient.so.6
and see if it can now find the libraries/files it needs.

Are you sure that the Setup.in path is correct?  I looked at both these
files build.py and MySQLdb.py they both refer to libraries and their
respective location.  Anyway good luck and if you get an answer, please let

I probably going to change over to mandrake linux for security reasons.

I've never used Caldera's distribution, but if it's anything like Red Hat,
the following should work:

1) Open /etc/ld.so.conf with your favorite text editor and append the
directory in which libmysqlclient is located.
2) Run 'ldconfig'

This will update the list of directories that the linker searches.

Let me know how it goes.

improved and there's certainly room for more. Perhaps there should be a 
coordinated 'wish list' on zope.org so that developers can pick up on 
needed products, or collaborate  on enhancements of existing products ?

Agreed <dml-var object> is a pretty good start for most people.

><var object="layout.table_footer"/>

><var object="footer"/>
></zopeglue>

Well that's a bit further than I was proposing. Perhaps I would settle for 
dtml which accessed the REQUEST object more simply. However your syntax 
looks good.

What "non-standard" syscalls? I'm talking about calls like lseek().

Yes, spawn a new thread.

WARNING this can cause havoc if not done properly.  For example, if you
want your seperate thread to be able to read and write data to the
database, you MUST open a seperate connection to the DB.  If your thread
goes away, you MUST close that connection.  There are a couple how-tos
on the site that explain database connections.

Yes, that makes sense. When it looks up "id" in the namespace, it first
comes across the id of your method. You're specifically wanting the "id"
from the REQUEST variable. So, the line should be:

<dtml-call "REQUEST.set('id',_.str(_.int(REQUEST['id'])))">

Nope. The Data.fs file is simply appended to when things change, and it is
quite safe to just copy the file over.

It *can* be done, but you would need to write your own ZODB Storage
mechanism for it. Right now, there are a few Storages available. FileStorage
is the most common (the one that works with Data.fs). There is also
CompressedStorage and BerkeleyStorage. No one has written a storage for an
RDBMS yet, but it should be possible.

Would you want to do it? Probably not. The FileSystem storage is pretty
solid. About the only thing you'll get from the RDBMS storage is that you
wouldn't have a file that keeps growing with every transaction and needs to
be packed from time to time.

Hi Chris (Carlson),
Thanks for the reply!

1.  I added the following line to my /etc/ld.so.conf file:
    /usr/local/lib/mysql
2.  I ran 'ldconfig'
3.  I re-ran build.py.  Here is the new error message. (notice that the last
line changed from before):
Traceback (innermost last):
   File "build.py", line 14, in ?
     import MySQLdb
   File "MySQLdb.py", line 19, in ?
     from _mysql inport *
 ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

Note that the file '_mysqlmodule.so' is in the
'/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' directory

4.  I tried adding '/usr/local/Zope/lib/python/Products/MySQLdb-0.1.2' to my
/etc/ld.so.conf file, re-running ldconfig, then re-running build.py, but I
got the same error.

It seems like we are getting a little closer!  Any more guidance would sure
be appreciated!

Thanks again,

Eric.

Subject: [Zope] Zope authentication problem
Message-ID: <v04220807b4ec46d1b515@[192.168.0.16]>

I apologize in advance for this note. I know this topic has come up 
several times in the archives, and I swear I've read every post, 
every how-to, and every other bit of documentation I can find. I 
can't get past the management screen authentication for Zope with 
Apache.

Here's my environment:

OS:		RedHat Linux 6.1

Zope: 		version 2.1.4, installed from Jeff Rush's RPMs (thanks, Jeff)

Zope PCGI:	version 2.1.4, also from Jeff Rush's RPMs (thanks again, Jeff)

Apache:		version 1.3.9, installed from the Red Hat RPMs (both base
		and devel RPMs are installed)

Python:		version 1.5.2, from the Red Hat RPMs


I'm configured as follows:

Zope install directory:		/var/zope

Zope.cgi:			copied to /home/httpd/cgi-bin/Zope
				(not a symlink, and renamed 'Zope')

access file:			/var/zope/access, contains:
				admin:cleartextpassword

httpd.conf contains:

RewriteEngine on
RewriteCond %{HTTP:Authorization}  ^(.*)
RewriteRule ^/static/(.*)   /home/httpd/html/$1 [l]
RewriteRule ^/Zope(.*) /home/httpd/cgi-bin/Zope$1 
[e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l]

(that last line is all one long line, and I'm pretty sure I've sorted 
out the ls and the 1s properly)



Zope is launched with the following command:

cd $INSTANCE_HOME  (/var/zope)
/usr/bin/env python z2.py               \
         -z      /usr/share/zope         \
         -u      zope                    \
         -Z      /var/run/zwatchdog.pid  \
         -p      /home/httpd/cgi-bin/Zope \
         -w      ''                      \
         -f      8021                    \
         -m      ''                      \
         -l      /var/log/zope           \
         2>&1 >> /var/log/zope           \
         &

I can access all my other (non-Zope) CGI programs normally. I can 
access my static html with URLs of the form:

	http://server.ucop.edu/static/some_silly_url.html

So, I'm pretty sure that both CGI and the rewrite modules are 
installed, configured, and working properly. I can run Zope and see 
the QuickStart materials, so I'm pretty sure that the basic Zope 
installation is correct. But I can't get authenticated to Zope. 
There's nothing in the logs for httpd or Zope that looks interesting 
to me:

httpd - access_log:

207.212.67.31 - - [08/Mar/2000:10:14:18 -0800] "GET 
/cgi-bin/Zope/manage HTTP/1.0" 401 1388

Zope log (syslog messages file):

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- - 
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782

/var/log/zope is empty.


I've tried about a zillion other things, including installing the 
Zope binaries instead of the RPMs, and installing and building the 
Zope source. In every case I end up with the same result. Zope 
doesn't accept the authentication. One oddity I noticed is that if I 
access Zope through:

	http://server.ucop.edu/Zope

it immediately requests authentication. It doesn't even show me the 
opening screen or allow me to browse the QuickStart. If I dodge 
around the RewriteRule by going directly to:

	http://server.ucop.edu/cgi-bin/Zope

then it doesn't ask for authentication until I try to hit the 
management screen.

I should probably add that I tried using the built-in Zserver Python 
package and it worked fine. I haven't tried Zap. I would prefer to 
use Apache because I want to serve a mixture of legacy HTML and Zope 
content. I would prefer to use my own Apache instead of Zap because 
in general I'm not comfortable with using a package that I can't 
maintain at the current release level. Zap Apache trails plain Apache 
releases, at least by a little bit. I've tried a whole raft of 
variations on the rewrite rules in Apache. I'm stuck.

Anybody out there been through this already?

We need a couple more data points before we can blame Zope for this or

Try just REQUEST.set('title', 'Foo')

Folder inherits from all kinds of other things, including
ObjectManager.  Basicly, if you want your object to be a container then
subclass ObjectManager.  If you want to look and walk and quack exactly
like a Folder, use Folder.

They have a getSize() method that returns the length of the Image (Files
have this too).

Sure.

Yes, any automatable HTTP client will do.  You might want to look into
ZClient, or xmlrpclib, or httplib.

Yes, because we haven't implemented it.

Yes it is, I'd like to see this too.  I don't think it would be too
complex for someone to do, certainly FTP support is fairly trivial.  For
this you would need to mine the source.

I don't understand.  Editing a DTML Method through the web should not
munge it in this way.

Create an new kind of Storage module that stuffs database records into
table rows, instead of a file.  We've hypothisized on this, and it is
very possible (the 'fs' in Data.fs means 'FileStorage', which is the
kind of storage used by default on Zope.  Other storages include
DemoStorage, BerkeleyStorage etc.  There is no saying you couldn't have
a RelationalStorage).  Butdo you REALLY want this?  Consider:

1) Relational databases do not store previous revisions of record
information.  You will have no Undo capability.  I guess with some
extremely fancy SQL or if you engineered the Storage to do some kind of
mapping, you could emulate the storage of previous revisions.

2) One of the benefits of RDBMS is that they can be used by outside
applications.  The data Zope stores however will be record objects,
basicly python pickles, information which is useless to other apps.

However, it's really not a bad idea, except for the no Undo part.

Yer gonna kick yourself if this is it, but I believe that you must have
a RewriteCond before each rule that you want the conditon to apply to,
so in this case your authorization information is poked into the
environment for your static content, but not Zope.

Duplicate the second line after the third and see if it works.

Subject: [Zope] Referencing a Zope Instance through a Hyperlink
Message-ID: <3.0.1.32.20000308144541.0068c798@bizux.net>

I have a group of ZClass (DCTasks) stored in a folder
'/tasks/generator/taskstorage'

The index_html of '/tasks' is the interface to view the instances and
certains properties that are saved on those instances. One of the
properties is 'task_title' and is displayed as a hyperlink to view the rest
of the properties of the instance.

This is my problem, when I check the source of the page (/tasks/index_html)
and I take a look at the hyperlinks for viewing the properties of the
instance, it gives a URL like so:

http://diis/tasks/generator/taskstorage/<string>

<string> should actually be replaced with the 'id' of the instance. This is
so by the DTML code for index_html:

<a href="<dtml-var URL1>/generator/taskstorage/<dtml-var id>">
  <dtml-var task_title>            
</a>

I have no idea why a string is taking the place of <dtml-var id> in
referance to the instance.

Any ideas would be helpful.

Best regards, 

MJ Stahl

Well, basically what you are doing here is moving the point of
potential corruption from zope to the relational database.  This may
or may not give you any comfort.  For me, it makes me more nervous
since I don't have the source code to those particular databases, and
thus couldn't fix things if the worst does happen.

World domination has nothing to do with it. If Zope were the only tool
out there (or if it were enjoying the same kind of monopoly iron grip on
the market), that'd not be a Good Thing.

At the moment, Zope is still very much a "guerilla" product. It follows
that you might have to use guerilla tactics to lure it into your
company. Like Linux was just 1-2 years ago.

Arguably, free software (or Free Software) is about freedom, not
necessarily about what's right or what works.

RMS, arguably the grand old man, top banana, and icon of the Free
Software movement -- which is not the same as Open Source -- openly
admits he'd rather have bad, free software than good, non-free software.
The Open Source movement takes the pragmatic view that bad, free
software isn't an improvement at all, and that the software industry has
little use for RMS' moralisms. The Open Source guys just wants "software
that doesn't suck".

Perhaps Free Software people don't care about marketing. But then making
good impressions or having good hygiene has never been top priorities
for geeks. ;-)  For some people, outward perceptions do count. I flinch
every time somebody sets up Microsoft Exchange Server, or buys some
pricey piece of non-compliant Internet software, or seriously argue the
significance of ASP.

The people who make such decisions are often, sadly, uneducated about
what's good and about "software that doesn't suck". *Other* people
suffer because of such misfires.

Here's a different perspective you might not have taken into account in
your salutations to the spirit of Free Software. If Linux *hadn't* been
picked up by huge corporations and stock markets, if Linux *hadn't* been
rampantly commercialized, would we have seen the surge of wonderful
developments and innovations for the OS that we're seeing now? Methinks
not.

As much as I abhor commercialism and the new Linux hype, Linux' implicit
"world domination" plan is doing good things for the OS. Linux is not
the ultimate OS and hopefully won't be the last stop on the way to
utopia, but I rather look forward to the point where it's usable as a
desktop OS and I can forever throw out the software I know for a fact
sucks.

Marketing, in the case of Open Source/Free Software, is mostly a tool to
educate ignorant brass. *We*, as you point out, don't need the stuff.

Subject: [Zope] Puzzling DTML method results
Message-ID: <4.2.2.20000308154134.00b99280@saladin.aisys.com>

I'm encoutering a puzzling result with some DTMLMethods that I've 
written.  I have some code which is used to display a list of information 
derived from a catalog.  The information presented varies, based on which 
"category" of information the user desires.  The DTMLMethod which generates 
most of this information looks like this:

<dtml-in "InternetLinkCatalog(meta_type='Internet Link Info', 
categories=_['categoryName'])" sort=name>
    <dtml-with "InternetLinkCatalog.getobject(data_record_id_)">
        < ... display object stuff here ... >
    </dtml-with>
</dtml-in>

For testing purposes, I created another DTMLMethod in the same folder named 
'categoryName' and initially all it contained was one line:

Accounting

When I displayed the contents of my folder (which utilizes the list 
generation method),  I received a list of all objects which belonged to the 
category of Accounting.  I'm now trying to extend my code to use an actual 
category name specified by a user (or from a url clicked on by the 
user).  I changed my 'categoryName' code to look like this:

<dtml-with REQUEST only>
<dtml-if category>
    <dtml-var category>
<dtml-else>
Accounting
</dtml-if>
</dtml-with>

If I view this method, the result is 'Accounting', which is just what I 
would expect.  However, when I attempt to view my generated list in the 
same manner as before, I get no results.  I'm confused.  When the 
categoryName simply has the value 'Accounting' in it, I see results.  If I 
change the method to include some processing (but still answer the same 
thing), I get no results.  I'm sure that I'm just doing something stupid a, 
but it's getting late in the day and I'm not seeing what the problem might 
be.  Can someone help explain why I'm getting two different results for 
what should be the same?

Thanks.

I bet your ZClass inherits from either DTML Method or DTML Document, and
then the following article applies:

Is this comparison available?

Or going to be available?

kb

>>> From: Patrick Phalen <zope@teleo.net>:

Yesterday, I was asked, by a client, to put together a side-by-side
comparison of Zope and Vignette for presentation to their IT managers.
I did a lot of searching on the Web, but found only the one article from
this list last October, which was written by someone with no experience
with either of the two!

Frequently, people have asked for this sort of data on this list, but
I've never seen a coherent answer. It's a FAQ.

Digital Creations might be able to help here, since they have direct
experience with clients who have started with Vignette and switched to
Zope. It would probably be "impolitic" for DC to author a public
article taking Vignette to task, but certainly they could help an
independent author with facts. If that article could then be published
in DevShed or Web Development, or another visible place, it would give
us all something to point to. Search engines would index it. The word
would spread.

Vignette is often characterized as the "industrial strength" CMS, so it
would seem a good target for a comparison, especially due to its high
cost.

I can't see the problem either, but I suggest changing your method to
this:

<dtml-if category>
  <dtml-return category>
<dtml-else>
  <dtml-return "'Accounting'">
</dtml-if>

The <dtml-with> is unecessary.  Note the single quotes inside the double
quotes.

This might fix it, might not, not sure.  But here you are explicitly
returning a string, not a formatted document.

Subject: [Zope] creator/owner attribute of an object? Mime-type of a file object?
Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AC@VRTMAIL>

I'm attempting to create a directory list (well, the final version will be
more complex, but this is where I'm stuck).  I'm looking for some way to get
the creator ID for all of the (file) objects in a folder.  I'm also
interested in getting the mimetype, but this is less critical.  Here's what
I have so far:

<dtml-in "PARENTS[0].objectValues( ['File'])">
url <dtml-var URL1>/<dtml-var id>
title <dtml-var title>
id <dtml-var id>
size <dtml-var size>
ddate <dtml-var bobobase_modification_time fmt="%m/%d/%Y">
owner 
mimetype <dtml-call "getContentType()">
</dtml-in>
<dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')">

Unfortunately, getContentType always seems to return null strings, and I
cannot find any attribute which shows the owner/creator attribute of the
object. If the creator is not available, the last editor would be fine.

Pointers appreciated,
Mike

Message-ID: <F32B7D6249C5D31187DB00C00D00F78C076EF8@weebo-2.osip.com>

Hello,

I've been trying to decipher the Zope member log in screens.  It appears
pretty straight forward.  There is the login.html screen which is basically
just a form for entering Name and Password and then passing this information
to logged_in.html.  I'll ignore the cookie for now.

logged_in.html then checks <!--#if "AUTHENTICATED_USER.getUserName() !=
'Anonymous User'"--> and reports success or failure.

However, as usual, there's got to be something I'm missing.  If I simply
build those two pages, the AUTHENTICATED_USER.getUserName()  check on the
logged_in.html page always return 'Anonymous User'.

When and how do I get the form to actually 'chat' with Zope and make me a
valid authenticated user?

Thanks in advance for any help provided.

	-mark

PS.

For those who are still having a problem with DCOracle and Oracle8i, that's
working great for me now.  If I can help, feel free to send me email.  I'm
running all this on RH Linux 6.1

I've been watching this debate since the begining and felt I'd put in one
observation on the above quotation. I actually think one of the comments in
this vain (maybe by ESR) was the goal for "software that sucks less" than
the whats out there. I don't think you can create software that doesn't suck
in some person opinion.

That said what I've learned is if I have to have software that isn't quite
where I want it to be I prefer the ability to adapt it myself. One argument
against open-source software projects is that they often come from amorphous
groups on the Internet. (Zope is an exception.) As a result there is no one
to "hang if it fails". What people don't factor into the equation is if I
have to pay $X for licenses from a vendor (with or without a support
contract) how many hours of contractor time will that buy me to install,
customize, administor, and maintain a freely available open-source product?

For those fighting this battle inside corporations I recommend
http://www.cluetrain.com as a place to visit.

That did the trick.  I hadn't thought about putting primes around a value

People are indeed working on Python, but not to the extent of more
popular projects like Linux or even, I believe, Perl.

Compiler/language projects have, historically, not thrived in the
collaborative world of open source software -- for very specific reasons
inherent in the concept itself of languages and compilers. Still, I'm
very impressed with the evolution of next-gen GCC (formerly EGCS).

I consider Skaller's Vyper project a fringe project with limited
applicability, because Ocaml itself is a fringe project -- it's
certainly not what you might call a mainstream, popular language.
There's something icky about an OcamlPython. However, I'd love for it to
succeed. (Unfortunately, Skaller is already out on a limb, implementing
all sorts of stuff he deems interesting -- so true CPython compliance
isn't necessarily on his agenda, and fragmenting Python like this is,
imho, not a good thing.)

Anyway, while I have not been monitoring the Python type/interface SIG,
it seems to be moving quite slowly.

I'm not saying they're holding back, but rather they're dismissing speed
and scalability as being a problem. I firmly believe that speed is
Python's number of problem today, and it's keeping Python from being
used in more applications.

Python has plenty of problems, but they're tiny by comparison and imho
they're mostly artifacts of Python's currently somewhat anemic syntax
(eg., only two kinds of loops, no "switch", no protected members, no
constants, no syntax for declaring mutability).

Imho Python's second big problem is what you might call, in lack of a
better term (I'm not wearing my compiler-writer hat right now, sorry),
contractual semantics -- anything from static typing (pass a string to a
function that takes an int and you get either a compilation error or an
exception) to interfaces (the ability to enforce semantic compatibility)
to design-by-contract constructs.

I disagree, but there's only one way to find out -- implement it (or
simulate it very carefully).

Not potentially. Definitely. I thought about this yesterday, and I got
to thinking that it would probably be pretty simple to create a dynamic
native-code generator that translated bits of bytecode on-the-fly, with
the necessary stubs implemented in a small helper-assembler written in
C. Something like:

  def Halibut():
    ...

  import codegen
  c = codegen.Translate(Halibut)
  c()  # Call native-code function Halibut

and then with whole modules:

  import pickle, codegen
  pickle = codegen.Translate(pickle)

Internally, Translate() would disassemble the bytecode, generating
native assembly language code and pass it to the helper C module, which
would store it in an executable buffer and fix up the necessary
references to the Py* API symbols.

Just a thought.

It would be an interim solution for certain CPU-intensive modules, in
anticipation of such built-in functionality in CPython itself. Possibly.

Well, I guess they're too busy arguing about whether Python should allow
assignments as expressions so you could do "while line = f.readline():".

Thanks,
The problem is fixed. The box with the ftp server had PARANOID host 
deny settings. This caused user's with incorrect reverse IP lookup
nameserver settings to be disconnected.
Sorry :-( 
You should all be able to download now (but maybe get in touch with
your domain administrator/ISP and get your DNS entries corrected, if
you previously had trouble ;-)

Cheers,

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * A Documentation Survey has been posted.  This survey will help
    Digital Creations decide where to focus our efforts by allowing
    you to tell us what you think about Zope documentation.

    http://www.zope.org/Members/Amos/Documentation/DocSurvey

  * "efm" has made a set of RPM distributions of Zope 2.1.4.

    ftp://www.tummy.com/pub/tummy/RPMS/

  * Maik Röder has posted an announcement regarding the Zope
    Documentation Project (ZDP).  Among other things, the ZDP has a
    new site.  It's a fantastic resource, and definitely worth
    checking out.

    http://www.zope.org/Members/roeder/zdp

  
New Products

  * Software Product: NFG Navigation Product, submitted by "gyst"

    Another product which provides navigation widgets such as trees
    and maps.

    http://www.zope.org/Members/gyst/NFGnav

  * Software Product: ZopeEDIT, submitted by "jimbag"

    This product allows you to edit DTML object from your Zope
    database in your favorite text editor.  Maybe.  Written in Python,
    so it just might work on your machine.  This is _not_ a Zope
    add-on, it runs on it's own.

    http://www.zope.org/Members/jimbag/ZopeEDIT


Updates

  * Software Product: mod_pcgi2, submitted by "phd"

    The update to 1.0.2 adds new documentation.  This is module allows
    Apache to communicate with long-running PCGI servers, such as Zope.

    http://www.zope.org/Members/phd/mod_pcgi2

  * Software Product: load_site.py with additional features, submitted
    by "Itamar"

    This is an enhancement to the load_site.py utility that comes with
    Zope.  It can be used to fill a Zope database with content from a
    filesystem.  This release, version 1.2, fixes all known bugs, has
    new features from the newest version of the original load_site.py,
    and runs in 'standalone' mode, loading into a remote Zope server.

    http://www.zope.org/Members/itamar/load_site/load_site1.2

  * Software Product: FSSession, submitted by "gaaros"

    FSSession allows you to store persistent, per-visitor information
    on your filesystem.  This update, to 0.3.0, fixes a number of bugs
    and properly supports Zope transactions.

    http://www.zope.org/Members/gaaros/FSSession

  * Software Product: KM|Net News, submitted by Kevin Dangoor

    KM|New News is a weblog (news site) product, not unlike (but not
    identical to) Squishdot.  This update is version 1.1.

Zope.org items

  * How-To: Managing http/https URL Links, submitted by "rbickers"

    This How-To describes a clever method to generate links to objects
    which require different protocols (http or https).  This allows
    you to use encryption only where needed, without using exclusively
    absolute links.

    http://www.zope.org/Members/rbickers/http_https_ulinks

  * How-To: How to view all inherited and acquired attributes and
    methods of an object, submitted by "dmost"

    This How-To is essentially an educational (or debugging) tool.

Hi Matt, Hi Jack,

What were your IMAP/SMTP settings prior to setting them to localhost?
Were they empty or pointing to a specific host name?

Cheers,
Ryan

In my case, they were, for IMAP, my local machine name, and for SMTP, my
ISP's (Roadrunner's) SMTP server.
IMAP has always worked great.  SMTP has been the problem.  I have not tried
Jack's solution, as I can't use localhost
for SMTP.

Thanks for any help,
Matt

I am getting a strange error when I try to access the Properties tab of
one of my objects called "News":

ErrorType: InError
ErrorValue: Strings are not allowed as input to the in tag.

The traceback is as follows:

Traceback (innermost last):

    (Object: getProperty(id))
InError: (see above)

What does an error in the input to an "in" tag have to do with accessing
the properties tab?

I could be wrong, but I suspect that this has something to do with an
assignment I made to a lines property that belongs to the "News" object.

Something to the effect of a string being assigned to a lines property?
(I make this assumption because I have had this error come up before
with lines properties. In this previous case, I just flushed out the
contents of the lines property in question using
"manage_changeProperties". This fixed the error, although even then I
never understood what the error in input to an "in" tag had to do with
the lines property value being erroneous.) As I no longer need this
property, I would gladly eliminate it. However, Zope won't even let me
in to the Properties tab. It just displays the "InError" when I attempt
to go to Properties of the News object. I can't really remember the
exact wording of the lines property id so I can't delete it via
"manage_delProperties" or flush out the contents of the property using
"manage_changeProperties".


Any insights as to what is going on and how to resolve this situation?
Please excuse the verbosity of this posting.

Message-ID: <CC59868A0A76D311B1F50090277B321C1F31AD@VRTMAIL>

I know, bad form responding to one's-own post, but I did figure it out and
thought other newbies might find it useful...  The first (trivial) problem
was that I had a typo (dtml-call instead of dtml-var) which prevented the
content-type from displaying.

"type" "<dtml-var "getContentType()">"

The creator/owner attribute can be got at by going through the
get_local_roles method then searching for a value that has "Owner" in it,
and copying the corresponding key.  I'm sure my dtml is atrocious, but hey,
I just learned it this afternoon :) .

"owner" "<dtml-in expr="get_local_roles()"><dtml-let
temp=sequence-item><dtml-if expr="temp and 'Owner' in temp"><dtml-var
sequence-key></dtml-if></dtml-let></dtml-in>"

Enjoy all,
Mike

Having a slow machine, not having to restart the server when testing is
important for me (it is a 20 second start up for me).
Is there a script around to let me do this... ?

Here is what I have done so far (using bits of snippet from the source):

log into the monitor, and do this:

import Zope
app = Zope.app
c=app()
OFS.Application.initialize(c)
c._p_jar.close()
del c

The net result is all items in the the "Add New Item" combobox double up,
and I am not even sure if this does the trick...

Good idea. Zope needs some more languages anyway.
Apache for example has mod_negotiation for this.

please not: the q argument is not meaningless.

I think a better way would be to implement a true negotiation mechanism.
That is, if the request comes, zope has to look for languages available
and rates them according to the language preferences coming from the UA.
Then it sends out the highest rated document, that might be the first
of the items in accept-language.
So each document (could be a folder?) schould have an attribute to
identify
its language capabilities. 

A simple branch would imply you have all documents in all requrired
languages.
I in doupt you can make this happen.

Easy with a second string.split(_.['sequence-item'],";")[0]

Subject: [Zope] Documentation survey
Message-ID: <14534.58177.603725.668441@antares.int.plain.co.nz>

As the tiny little text box on the survey page isn't up to long
dissertations, I'll post my comments here:

The guides need better examples and blank spots filled in, in
general. The DTML guide, in particular, needs a canonical explanation 
of the quoting rules and shortcuts so new DTML hackers understand why
you can get away with this:

<dtml-let foo=bar> ... </dtml-let>

But still need to do this:

<dtml-let foo="'constant'"> ... </dtml-let>

There is still a lot of docs using the old, ugly HTML comment style
tags, too, which is confusing, and there are a lot of examples of
using '_' and REQUEST to kludge up a temporary namespace when
<dtml-let> is the accepted means to kludge up a namespace[1].

The HOWTOs and Tips are potentially the basis of an excellent Zope
cookbook, but they require more stewardship from DC:

- They need more structure. Catagorizations like
'Authenication/Authorization', 'Using RDBMSs' and 'DTML tricks' would
save a lot of search time and provide hints towards missing
documentation. 

- The need to be vetted. There are a lot of docs with incorrect
examples and obsolete information that need to be tidied up. 

John

[1] Who the hell came up with a scoped assignment tag?! Why not
implement a <dtml-set> tag that isn't a container and that assigned to
a temporary namespace that persists for the duration of a DTML objects 
rendering. It can have a special attribute that you use to commit
changes made to an object in the temporary space back to it's
persistent name space, and you'd have a decent assignment tag.

It is the name of a method that will be called when the File is accessed.
You can use it for checking a session cookie, or anything you need from the
REQUEST.

If you then want to deny access to the resource, because your precondition
hasn't been met, the method can raise an exception.

I dont know if this is possible, but one feature of any tree-transformation
language that might be usefull to me would be the lazy construction of
nodes, or the creation of a virtual tree that is in fact a live view of the
source tree. XSL seems to be designed as a batch-processing language, which
seems at variance to the principles behind zope.

fmt="..." accepts any printf style formatting string.  Grab your handy C

No, sorry.  Python has a 'reload()' built-in, maybe that could be

Message-ID: <4.2.2.20000308192207.00e638e0@127.0.0.1>

I'm new with Zope.

One thing I'm looking for how to do is the effect that one document might 
virtually be stored in multiple folders.

For example, if I keep a hierarchy of folders that is an archive of 
articles, maybe stored chronologically in a folder for each month or 
something like that. But then I also want those same articles to appear in 
other folder hierarchies, categorizing and organizing them in various ways. 
And I don't just want to put duplicates of the document in there. I'd like 
that if somebody updates the original, the virtual documents in the other 
folders update too.

Is there some obvious DHTML statement or trick I don't know about yet? Or a 
Product that does something useful about this? Essentially I'm looking for 
an equivalent to symbolic or hard links to files in a Unix file system.

Subject: [Zope] what defines the absolute_url() prefix?
Message-ID: <38C72738.F8CB3EB8@picknowl.com.au>

G'day,

I'm having a blast using (technically: playing with :-) Zope 2.1.4 on
a RedHat 6.1 box, and mod_pcgi2 (1.0.1).  For my first efforts, I've
built a set of DTML methods which emulates www.python.org's style of
website, with an index_html method that "includes" Banner, Sidebar,
Body etc methods, which can be over-ridden in lower-down folders. 
All funky stuff, works well.

In the Sidebar, I have links to folders within the site using
absolute_url() (because of issues with BASE HREF giving me multiple
folder syndrome).  I can access the folder with the URL
http://localhost/cws/Help (and the logfile shows "GET /cws/Help"), but
the absolute_url() method on cws.Help is actually returning
"http://localhost/cws/cws/Help" (which is also accessible - kinda odd,
but not what I want).

I kinda suspect I've screwed the mod_pcgi2 config, mainly because its
the area I'm the most confused about :-)  I have the following config
in Apache:

<Location /zope>
    SetHandler pcgi-handler
    PCGI_ROOT /
    PCGI_SetEnv SiteRootPATH /
</Location>

<Location /cws>
    SetHandler pcgi-handler
    PCGI_ROOT /cws
    PCGI_SetEnv SiteRootPATH /cws
</Location>

(Oh, and I've just added a <dtml-var REQUEST> to the Help page, and
it's returning URL http://localhost/cws/cws/Help/index_html for
accesses to http://localhost/cws/Help, so it's awfully consistent
in its behaviour.

How does zope determine what the prefix is, and better yet, how do I
fix it to mesh with reality?


Regards,
  Daryl Tester

Flemming,

What you have described is exactly what Acquisition does.  Say you put a
document 'DocumentFoo' in your root level folder.  You could access that
document a number of ways:

/DocumentFoo

/AFolder/DocumentFoo

/AFolder/AnotherFolder/DocumentFoo

this happens for you automatically right now.  Try it youself, create
some folders, put a document somewhere 'above' them (like in the root
folder) and it will work.

Subject: [Zope] fast cgi
Message-ID: <003b01bf8988$d50e3960$0402a8c0@toil>

Exactly how do you get zope to work under apache with fastcgi?

I found 2 documents on the zope site dealing with this issue and they both have
command options "-pass-header Authorization" like
FastCgiExternalServer /home/httpd/html/z -host localhost:8999 -pass-header
Authorization

This produces an error as an invalid option, and looking at the documentation for
the FastCgiExternalServer directive it is not an option. The version of fastcgi
is 2.2.2 which is the same version they say to use in the documentation.

Does anyone besides Digital Creations know how to make this work? I have tried
this a bazillion ways from apache rpm's and binaries, but can't get it to work.
Someone must know how to do it.

Thanks

If you look around at Zope.org, you'll see that most content physically
resides in Member folders. But the same content can also be found through
the Documentation, Products and Reosurces pages.

We use the ZCatalog for this. You can build up pages with searches, thus
allowing multiple views into your content.

We are currently developing a thing called 'Topics', they exploit this
feature in an automated way. You specify a search on them, and they will
thus model a view into your indexed content. This way you can generate pages
with your articles by month, or by topic.

I think he typoed 0.2.3 instead of 0.1.2. 0.1.3 is out as of today (or
yesterday), but shouldn't offer any improvement in conjunction with Zope,
so you don't need to rush out and get it.

The main hurdle that people installing MySQLDA with MySQLdb seem to have
is, they want to try to compile the stuff in the src directory that
ZMySQLDA provides. This is MySQLmodule, which is the old interface. Just
rm -r src. There is a patch that comes with MySQLdb that needs to be
applied to ZMySQLDA. Once you've done these two things and installed
MySQLdb on your PYTHONPATH, you just need to restart Zope, and make a
ZMySQLDA Connection object (or whatever it's called).

I don't think a new syntax should be brought about. There are too many things
to learn already, it will only add to the confusion.

I do agree that dtml is complex and something needs to be done about it.
Probably a subset of the current dtml itself - with minimal additions which
make somethings easy - would be good.

Also (if this is seriously being considered) I would favour for a somewhat
different paradigm:

Instead of:
> <var object="layout.table_header"/>
> <in object="get_above_age" arguments="age">
> <var object="myrecord" arguments="in_item"/>
> </in>
> <var object="layout.table_footer"/>

We could have:
<dtml-var object="layout.table">
<param name="datasource" value="get_above_age">
<param name="columns" value="Name,Age">
</dtml-var>

The advantage here is that:
   o   One logical presentation element (a table) is one element in dtml code.

   o   One-to-one relation is possible between the code and any GUI entity
        being used to design (think ZStudio). This means the layout.table can
        be one icon that is dropped into a design view and it's parameters
        specifed through some fancy widget. 
        Also when the code is stored and reloaded, it would still be
        possible to display the same GUI entity in the design view and it's
        parameters would be editable.

Discussions on the above have taken place on the ptk and zope-moz lists.

That is a very peculiar error. Py_InitModule3 is a symbol from Python
itself, so if that's missing, I don't know what's wrong. Well, I can guess
a little, and my guess is, while you have Python installed, you don't have
the development libraries. With RedHat, this is python-devel, but may be
something else with Caldera. Actually, Py_InitModule3 is a macro in
Python.h, so if it's looking for that, then Python.h is probably not being
found, which could mean that the -I flag in Setup (or Setup.in) is not
right for your environment. But you would have all kinds of build errors,
I would think.

Try this:

find /usr/include -name Python.h -print

If nothing comes up, then the development stuff isn't installed, or it's
installed somewhere else.

I'm getting better but stil learning.

I want to collapse/expand a tree at will so that
I can come in from particular hyperlinks to a known
tree state.  I know there are two variables I can set
but I don't know how to do this from code.

For example how could I have a hyperlink whose HREF
is a page containing a tree in such a way that when
you get there the tree gets collapsed while another
link to the same page doesn't collapse it.  Can
someone show me some code that dows this please.

Subject: [Zope] Zope Question : Virtual folders / URL's
Message-ID: <009301bf89a9$afced7b0$0201a8c0@iridium>

Have been reading the docs but still not clear on a few things.

I have my site mapped out in my mind. It has URL's like :

mysite.com/          (main page)
mysite.com/rss     (rss content for mysite)
mysite.com/<username>  (main <username> page)
mysite.com/<username>/rss (rss news content feed for <username> page)

Where I come from data belongs in a database. I'm happy for all my HTML to
be in the ZopeDB but not any application data (users definitions, news items
etc etc).

So, looking at my URLs I see that there are a mixture of static and virtual
folders.

mysite.com/index_html is obviously static though it contains dynamic
content. Doing this with Zope is easy and obvious.

mysite.com/Fred/ is a dynamic page. Fred only exists as a username in a
users table and related information in other tables. It's not obvious to me
how I go about serving this page because I can't create a static page for
every username (nor do I want to).

Clearly mysite.com/Fred/rss will use almost identical processing to the
mysite.com/rss page, just different parameters so re-using my "rss"
generating code is important to me too.

I'm know these virtual folders can be served up by Zope. Can someone tell me
what I am missing?

Last I heard about this, the status was "Not available".
http://lists.zope.org/pipermail/zope-ptk/2000-February/000323.html

But soon (hopefully!), I'll be releasing iTrack - an Issue Tracker Zope
Product. I haven't really used the ptk tracker so I can't give a comparison.

Well, it's a "feature" I can live with (otherwise it wouldn't be working
at all :-).

Tried that too, no joy (with all possible combinations of PCGI_ROOT and
PCGI_SetEnv, as I don't exactly understand its affect on Zope itself).

The dump from the REQUEST Session state shows (for both settings of
PCGI_SetEnv, plus some judicious editing):

URL:		http://localhost/cws/cws/Help/index_html
URL0:		http://localhost/cws/cws/Help/index_html
SERVER_URL:	http://localhost
REQUEST_URI:	/cws/Help
PATH_INFO:	/cws/Help

SiteRootPATH: changes (from /cws to /), so that's something.  :-)
From an environmental point of view, things appear OK (but what
would I know, I've only be using Zope for just over a week).  I'm
not sure how absolute_url() is constructing the full URL, but I guess
it would be from those above components (there doesn't appear to be
anything that defines the absolute hierarchy that I can find).

On a whim, I tried http://localhost/cws/manage, and the urls on that
page suffer the same problem too (eg, in the left hand frame there are
links of the form "http://localhost/cws/cws/Help/manage_workspace").
At least it's not just my DTML methods. :-)

Subject: [Zope] Indexing dtml/html files
Message-ID: <v04205508b4ed3dfc6467@[130.227.115.35]>

Hi,

Is it possible to use catalog to index ordinary html pages intelligent ?

If I have a html(dtml) file like:

<HTML>
<p id=title>
Are you Intelligent ?
</p>
<p id=author>
A. Einstein
</p>
</HTML>

I would like to index the title and the author id's, for which I could search.

Is it possible ??

   Well, let's me clarify a bit. PCGI_ROOT is the folder (or other object)
in Zope which will serve your requests. In your situation it is folder
"cws" in root folder.

   PCGI_SetEnv is *only an example* of how to set per-request environment
variable. Whatever variable you'll use and what value to set - it is up to
your configuration. In my example it is variable SiteRootPATH.

   This variable only works with SiteAccess. I use SiteAccess pretty
happily, and it solves all my virtual hosting needs, including rewriting of
BASE, absolute_url, etc.

   Without SiteAccess you'll get exactly what you get - additional path
components.

expand_all and collapse_all are all very well but I think Andy is after the same
thing that I gave up on. 

How can you expand or collapse a tree to a specific point, ie:

- make a particular subtree expanded 

- make sure a particular node in the tree in visible

The Zope DTML guide mentions the tree-s, tree-e and tree-c variables but it
doesn't explain how to use them. I haven't found any help anywhere on this.

Any ideas?

That's true, but that shouldn't hold us back indefinitely; some things are
can only be improved after a while if they're redesigned from scratch, 
otherwise the back-compatibility issues become too complicated. I don't know
if DTML is at this state though, and any new language proposal should be 
something to consider for the (very) long term.

But you lose some flexibility in defining table headers and footers;
you have to be careful your simple language becomes too rigid, making
too many assumptions.

Hm, what you're proposing is some higher level object (a product) that
does tables (in this case). That would in fact be rather neat.. Our simple
glue language could become extremely simple if we have sufficient higher
level components, and if it's easy enough to code up your own components.

I'm doing something like that for web forms in my ZFormulator product.

Okay, this kind of discussion probably belongs on another list, I agree. :)

I guess you could do it in XML-documents, that are
inherently more machine-readable than html..
Otherwise, storing title and author in properties would
do the trick for zcatalog..Not exactly what you ask for, but
as close as i can get with my skills..
I guess you could write a pythonmethod to extract title
and author from the html and store them in properties so
that they could be easily indexed..

Usin tree-s/c/e is going to be a bit problematic.

In my understanding those vars are built from the context of the node in the
tree, so if you add/remove anything to/from the tree then the tree-s/c/e
will change.

There doesn't seem to be anyway of going to a particular point in a tree
with any certainty.

I did this on one site for example, it's a prospectus for a college, the
tree is built from calls to a sql database.  Adding or removing records from
this database totally changed the tree-s/c/e vars that each node is
associated with.

I hope I'm wrong about that but I have a horrible feeling that I'm right.

Please someone prove me wrong.

actually I do have xml documents also but it is for an automatic 
system where the upload is done via webdav or ftp. So I need a way to 
upload Zope xmldocuments from a client.

I am not a Python programmer and would rather find a solution without 
doing some coding. But I have found the urls to find and update the 
index from the client. But now I need to upload xml documents to Zope 
AS xml documents. Is there an easy way to this ?

I don't know enough about Perl to judge this, but to me, there's
plenty of activity out there. Of course there could always be more,
but lots is happening.. We have _three_ independent implementations of
Python, for instance (Python, JPython and Vyper, and then there are
projects like Python2C).

Sure, it's not easy to do. I would debate that compiler/languages have
not thrived in the open source world, though. There seem to be
quite a few successful open source languages around.

[assessment of Vyper with which I agree]

That's the nature of discussion lists, almost. There are some prototype
implementations of type-checking systems for Python, though (I think
two or three independent ones, in fact).

Hm, but in my experience Python has been shown to be plenty fast enough
for the majority of applications. You're probably right though, and I
agree completely that a faster Python would be very nice.

I suggest you go discuss these things on comp.lang.python. :)

I don't miss switch. Functions are first class objects, and dictionaries
can be used instead of switch when necessary. Also, good object oriented
design tends to kill switch statements anyway.

I think the two loops are fine, though it would be nice to have the
current constructs to know about iterators. I believe Guido is
taking that into consideration. Also there's the list-comprehension
proposal which may help here. 

I don't think you'll see protected members any time soon.

I'm not sure what you mean with syntax for declaring mutability, though
it sounds interesting.

The types-sig is reaching consensus about optional static typing and
Guido does want to include that into the language in the future (beginnings
in 1.7, full implementation in Python 3000 aka Python 2). Interfaces are
being considered too, and Jim Fulton in fact has an interfaces proposal
out there (that may get used in Zope's code base).

I think using a unit testing framework can substitute for design by 
constract constructs myself.

Okay.

[snip code generator extension idea]

Something like that would definitely be neat. The hard part would be
in the translation process, of course. The other part is in the
interfacing with regular Python; do you allow your translated function
to refer to other Python objects? If you do, you're opening a can of
worms. If you don't, then it starts to look like the 'Swallow' subset
of Python I proposed once; a strict subset of Python with added full type
annotations, which is translatable into C or native machine code.

If you're starting such a project I want to hear more about it!

Not to mention indentation! Anyway, the people who keep bringing these

PCWeek did a shoot-out of various CMS packages about six months ago. 
They created a "scoresheet" that might be useful.  Unfortunately,
Vignette stood by their policy of not allowing their software to
reviewed, so it includes several other CMS packages.

Message-ID: <4.2.0.58.20000309114320.01881df0@192.168.0.2>

Hello Darran,


building on Rik's previous answer, how about this:

   <dtml-call "REQUEST.set('myObjRef', _[desired_id])">

It tested OK with an Image object called "image" and located in the site root:

# Storing the image name in a variable
<dtml-call "REQUEST.set('desired_id','image')">

# Creating an object reference based on the variable
<dtml-call "REQUEST.set('myObjRef', _[desired_id])">

# Displaying the object title and size
<dtml-var "myObjRef.title">
<dtml-var "myObjRef.getSize()">

# Rendering the object if it's renderable. An image is.
<dtml-var myObjRef>

If it's not renderable, you'll end up with something like "<Folder instance 
at 01368880>" in the HTML page source code.

Does it work for you? If yes, you may want to add a FAQ Question and it's 
Answer on zdp.zope.org (hint, hint :-).


Cheers.

The answer in my case is both.
My test box is called "geezer" so initially it was set to "geezer". This
designation works with other IMAP tools (ishmail, Netscape). When this didn't
work I tried the FQDN: geezer.lab.jacku.com (My exposed FQDN is different due
to masking by the cable modem company.) This provided a similar error. Reading
the doc files I decided to leave the fields blank. This also generated an
error. (I don't remember at this point if it was the same exact error.) After
that failed I entered local host for both options and it worked. This became
the "last test" since its result was positive.

Hope this helps.

Hi Folks,

I sometimes et the strange and quite inconvenient problem that the
treeview of the manage interface gets spacing of a few cm's between the
(+) sign and the folders on any folder below the 2nd level. The result is
that the tree is quite wide. Does anybody else have this problem?

It seems to be happening if more than one or two branches are expanded,
but I haven't pinned the exact problem down yet. I use 2.1.4,
debian-packaged zope. Is this a known bug, can I help in some way in
tracking it down?

If there is a 'multiple select' on the property sheet with no value
initialized, you can get this error.  This seems to be a long-running
bug with multiple selects.  At the moment, it is important that the list
(or lines property) has values before creating the multiple select, and
then you must establish a value for any new multiple-select by selecting
one or more of the items in the multiple select as soon as you create
it.  I think the bug is in the collector, but I cannot be sure.

HI,

In the python interpreter I have done the following things:
>>>import sys, ZODB, ZODB.FileStorage
>>>db = ZODB.DB(ZODB.FileStorage('/usr/local/zope/zope214/Data.fs'))
>>>root=db.open().root()

Where 'Data.fs' is my Zope DB with a lot of stuff. Then I did the following
things:
>>>root.__dict__
>>>{}			#result of the previous "command"
>>>dir(root)
>>>[]			#result of the previous "command"
>>>vars(root)
>>>{'container' : {}}	#result of the previous "command"

I expected to find the stuff I have in my Zope DB. I double checked to look if
I didn't made a typo on the longname of my Data.fs file, but all seems ok. I
also saw that the modification time of Data.fs.lock and Data.fs.tmp were set to
the time I run db=ZODB.DB(....... so I guess I chose the right Data.fs file.

Can someone tell me where am I wrong?

Thanks

Hi,

When I have a form with a <textarea> field set to submit to an sql
method, ['it gets stored','like this']. How do I get around this? Do I
have to do some special formatting before submitting to the SQL method,
or is there something I must do in the SQL method declaration itself?
I'm using <dtml-sqlvar fieldname type=string> because this was the best
I could find in the documentation. Is there a type=lines? If there is,
someone please put it in the ZQR.

Another: I want a text holding ZClass for storing text pages. Deriving
from DTML Document or Method seems the obvious choice but I have an
issue with that: the content must be rendered thus:

<dtml-var standard_html_header>
<dtml-var raw newline_to_br>
<dtml-var standard_html_footer>

I suppose I have to override rendering for my ZClass and insert this
code. How do I do this?

Hmmm....

Very interesting, I agree that installing Zope on Win* was very easy. The
problem I have is how to Sync stuff between my local Zope at home (no net
connection) and the 'real' Zope at work.

I currently do an export to a ZIP disk, and then an import back into the other
Zope from the disk. This makes a lot of things possible but only in very limited
circumstances:

You have to move *all* of Zope, or objects don't re-import back into the correct
place. Also, if an object changes on the 'real' Zope changes while I'm at home
and I import when I get back, the changes are lost as my import overwrites
whatever is there...not pretty.

Also, I can't do this trick with things like Squishdot postings, which is a
shame...

What would be nice is something like Lotus Notes replication when you import a
.zexp file; you get a replication conflict if both objects have changed, which
you can then sort out.

I'm not looking for the full-blown ZEO distributed object store, just a way to
periodically sync a set of selected objects (slightly more complex in the
squishdot case...) by exporting from one and re-importing (non-destructively)
into another.

Any ideas?

Hi,

  Is there any way in Zope to validate information
(news, new document) by third party before real
publishing.

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  How can I do this kind of things with Zope? Is it
possible?

  Any suggestion? links? help?

Message-ID: <4.2.2.20000309104029.00be1b50@saladin.aisys.com>

I know that there have been several threads on this list concerning the way 
to pass arguments to a DTMLMethod.  I've done what I think is correct, yet 
my result is less than pleasing.

Here's what I have and what I'm doing.  Hopefully someone will identify 
what I'm doing wrong.

In my web sites root folder (aka /Foo), I have a DTMLMethod named 
"siteRoot".  It simply answers "Foo".

In a subfolder of Foo, I have a method named "linkFor".  The code for this 
method looks like this:

/<dtml-var siteRoot>/SomePage?option=<dtml-var optionValue>

In the same folder that contains the "linkFor" method, I have another 
method which wants to use the result of the "linkFor" method.  In this 
method there is a line which looks like this:

<a href="<dtml-var "linkFor(_, _.None, optionValue='some value')">">Some 
Text</a>

When this code gets executed, I get a "KeyError" on "siteRoot".  For some 
reason, when my linkFor method executes, it can't see the siteRoot method, 
even though the method exists in the parent folder.  What am I doing 
wrong?  Why can't linkFor see siteRoot?

Thanks.

Message-ID: <NDBBLENPLCPAHKODFHNGMEHKCNAA.morton@dennisinter.com>

I have never seen the Python interpreter crash in any way, nor have I heard
of it doing so. I havent seen this, but my partner tells me he as seen the
Perl interpreter crash. I have seen the Java JVM crash many many times. Some
of my Python code has been running 24/7 for the last 18 months.

I would say that, as languages or interpreters, Python and Perl are equally
and extremely stable. As tools for developing software, Python's object
oriented foundation is conducive to the building of more stable _systems_
that Perl. This could be because of the language itself, or because of the
programmers it attracts.

Most of the Perl programmers I have met are, frankly, obscuritan mess-heads.
The concept of structured programming is somewhat anathema to the Perl
programmer. I looked over the shoulder of one Perl programmer we had hired,
who was having trouble with a database import problem for several weeks.
This Perl programmer had written 6 pages of perl code without actually using
_any_ indentation. The program was full of nested loops and she was having a
difficult time debugging her code. Without knowing any Perl, I cleaned up
the indentation, fixed a few glaring problems, and handed it back to her.
She had the problem solved at the end of the day.

It comes down to this: It is hard to write a program in Python that another
Python programmer (or the same programer several months later) wont
understand. It is easy to write a program in Perl that another Perl
programmer wont understand.

As for the outside consultant. Ask them what makes them feel that Python is
less stable than Perl, and what exactly that means.

   There are mnay ways you can do it. Publish it in some hidden location
and later move it into public area. Use Versions. Develop your own
mechanism for publishing...

  Is there any way in Zope to validate information

  For example some people are alowed to put a document
in the folder but these documents must be validate by
some one else for real publishing.

  Any suggestion? links? help?


[RH] There are several ways to accomplish this:
You could put the document in an 'incoming' folder and make a reviewer move
it to the publishing location (this also allows for letting the reviewer add
keywords/categories etc).

If the uploaded document goes directly to the documentation where it is
published, you could give it a property called 'approved'; reviewer invokes
dtml method which sets the approved property to 1. The document is not shown
unless the ' approved' == 1.
[untested simplistic dtml]

<dtml-unless "approved==0">
   <dtml-var <document>>
</dtml-unless>

I believe the Squishdot product
(http://www.zope.org/Members/butchland/Squishdot) allows for something like
this.

A third (more sophisticated) possibility is to combine the two approaches by
using the Catalog, more or less like the Zope site does:
contributions by members are submitted for approval to the Zope site
administrators, who then add them to the site's catalog. Then they are
available in pages that use the catalog for their contents (like the howto
pages, the products pages etc). In your case reviewers could also add
keywords/categories etc to the document before it is cataloged and the
catalog may index these. I do not think the Zope site approach is available
for the public, but it shouldn't be too difficult to implement it.

A related product is ZDP tools (http://www.zope.org/Members/roeder), which
does not exactly do this but may be a source of inspiration for workflow
management. Another workflow system in Zope is Xen (I do not have the URL
handy right now), but this may be overkill for your needs.

Hey James,

Just in my experience I have never had a problem with the stability of
either Python or Zope. I have set them both up on multiple servers (RH 6.0,
6.1) and been pounding away at them for months now. Python 1.5.2 has been
out of awhile (a year?) and Zope releases are certainly stable. In fact,
having been using Python for web CGI scripting for 4 years now I have never
had a problem with the stability of it as a language (run it on NT, Mac,
Linux and Solaris boxes). I usually just build it and let it leave it, never
needing to look back till I am ready to update it.

2 folders are next to each other, one is called test1 the other test2. They
are within the same Home folder, but one is not within the other. Can an
index_html document in test1 grab a dtml-var from test2? How is this done?
In html i would simply write ../test2/dtml-var. This does not work in Zope.

Message-ID: <v04220803b4ed7c0e4906@[192.168.0.16]>

I can confirm and reproduce this problem, and on a totally different 
architecture - Red Hat Linux system with Zope 2.1.4. Here's a snippet 
from my /var/log/messages file:

Mar  8 10:14:18 akpi ZServer[24689]: 127.0.0.1- -
[08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782


Notice that the timestamp from the syslog facility is the correct 
local time, March 8 10:14:18, which is Pacific Standard Time. On the 
very same line, the timestamp passed to the syslog from Z2 is in GMT, 
08/Mar/2000:18:14:18 -0700. My guess is that Zope isn't picking up 
the $TZ environment variable. What I don't get is why it's showing 
GMT as 18:14:18 -0700. That would imply a local time of 11:14:18. I 
think it should be 18:14:18 -0800 right now, and -0700 during 
daylight savings time. Two, two, two bugs in one!

I think you are safe in classifying this statement as FUD.  I've been
using Python (outside of Zope) for five years.  I even had a non-trivial
accounting system that my business depended on running in Python.
A bad design decision on my part led to some real problems with memory
size and CPU use of the resulting program, but Python never crashed
no matter how much data I tried to shoehorn into my badly designed
system.  Python is rock solid.

So does KM|Netnews (available on the products page on zope.org).
If it doesn't meet your publishing needs, you might want to look
at its code to see an example of a way to do it.  (I haven't looked

I have a simple two field table in MySQL, "whowhat", that pulls a user id

"what" classes)

I , being somewhat new to python & Zope, am having the darndest time trying
to do a simple external method to do a count of how many times the class
"so-and-so" is in the table. (That way, I know how many people have
signed-up, and how close I am to the class max.)  I have tried different
searches.  I have an SQL Method that does:

select * from whowhat

And I also have one that does:

...
select * from whatwhat where classcode = <dtml-sqlvar class_name type=nb>

I've been trying to create an External Method, but I just can't seem to get
it to work. (yes, in the Extentions directory)

I need to try to stay away from doing a "select count(classcode)..." in an
SQL Method if I can.

Any help to this tormented soul would be greatly appreciated.

<dtml-var "parents[1].test2.index_html">

would get index_html from ../test2 in a dtml document in ../test1

<dtml-var "parents[0].test2.index_html">

would get index_html from ../test2 in a dtml method in ../test1

There are other postings on why there is a difference between documents and
methods if you care...

Subject: [Zope] Having slight problems with <dtml-calendar>
Message-ID: <3.0.1.32.20000309114825.00698938@bizux.net>

Problem:
  Currently I have no problem view the HTML tables of the calendar or
adding properities. Where my problem lies is displaying those properties in
the tables of the calendar.

Currently the variables for the date, whether the object has a property,
and the value of that property are registed just like the <dtml-calendar>
How-to.

<dtml-let d="date.Date()"
          hasdate="hasProperty(d)"
          dprop="getProperty(d)">

The 'd="date.Date()"' does what it is supposed to. (make d equal to
something like 2000/01/17). I checked the hasdate variable and found that
it was equal to a 0 (1 if true, 0 if false, of course).

The properties are kept on the folder, where the calendar method is. I
added a property via the method for doing such and went back and checked
the folder to see if it had a property on it. Yes it did... in this format.

Tree Structure:    /diis
                     /calendar (contains the properties)
                       index_html (displays the calendar)
                       /updatecalendar
                         index_html (used for editing the properties)
2000/01/17 This is the 17th day of January.

Yet, hasdate was equally 0 (false) therefore the 'dprop' value could not be
set.

I guess my question is this:
  If the folder containing the calendar method has properties on it which
are   to be read into the tables of the calendar, does this mean that
'hasProperty(d)' is not being read off the folder and is looking at some
other object for the value?  

If that is not the question can someone please point something out to me
that I am doing wrong...

All help is extremly appreciated.

Best regards, 

Mark J. Stahl

The testamonials continue...

I wrote a perl app a few years ago for a customer, about 10,000 lines.
It produces a book in postscript from a database of info. They run it
once a week. It crashed at random. After 6 months, I couldn't read my
own code, comments or not. I ended up rewriting in Python and it has run
without a hitch for about 2 years AND I can still read and understand
the code. I hesitate to write a thing in perl anymore, and if I am
forced to, won't support it. I've had Zope and numerous other programs
in Python running without one crash EVER! Believe it!

It really depends on how bad your intentions are. Could you use
subclassing? Or do you want to add methods dynamically after instance
creation?

I am not sure what you mean by dtml-var but I assume you want to access
some attribute in test2. You can make test2 attributes accessible in test1
by:

<dtml-with test2>
tarari tarara
</dtml-with>

Message-ID: <20000309110821.A2683@devware.com>

I have seen a couple of people mention zope lockups on here before and
I haven't seen any myself until just recently.  (I have zope on about
5-6 machines and this is the first time I've seen this happen)
Anyway, how can I diagnose this problem?  So far I have only seen it
happen twice, but it was twice in the last 24 hours, and I'm getting
ready to roll out this app to some users.  I'm concerned!  Anyone have
any suggestions?

Symptoms are basically that it just stops responding.  The web browser
seems to connect, but it never completes the connection.  Right now I
have it running in debug mode to see if I can catch whatever it is
with some console logging.  This is on an NT Server running NT 4.0

I believe you have to supply the (_.None, _)
parameter for the index_html method to work.

You are ALMOST ALWAYS better off using the
<dtml-with ...> tag, something like

<dtml-with test2>
  <dtml-var a_something_inside_test2>
</dtml-with>

Or in the more general case of many layers

<dtml-with "FolderA.SubFolderB.SubSubFolderC.test2">
  <dtml-var methodA>
</dtml-with>

This pushes test2 onto the namespace stack. So
your methodA can still access objects inside
the SubSubFolderC.

------------------------------------------------

Use the dotted notation, e.g:

<dtml-var "F1.SF2.methodA(_.None, _)">

only if you don't need any objects from the
subfolder F1.SF2 during the call. Most of the
times, this is not what you want.

In this case subclassing won't work and I'm not needing to do this

Subject: [Zope] Finding crash information
Message-ID: <m37lfcawfm.fsf@wacko.pdx.net>

I'm having a serious problem with my Zope server running in
production.

Platform: RedHat Linux 6 (2.2.12-20 kernel)
          Python 1.5.2
          Zope 2.1.4
          starting with: python z2.py
                         as root/nobody on port 80 straight ZServer


Under load (not too heavy, but busy) the Zope process SILENTLY stops.
I get no traceback info anywhere that I can see.  Nothing to
stdout/stderr, nothing in Z2.log.

If I start as: python z2.py -Z '' to prevent the fork and detach I
still get no message when the crash occurs.  

I can't run this in DEBUG mode because I'm using GUF cookie mode to
authenticate and the login screen ends up showing an exception error
(by design?)

If anyone can tell me how to run in DEBUG mode but make GUF still hide
the exception error that would be a big help.

If anyone can help me keep this server from crashing every forty-five
minutes I'll buy 'em a beer next time they're in Portland.

-Jon

BTW, the site is very non-exotic.  GenericUserFolder with a lot of
static content and one ZCatalog w/CatalogAware ZClass.

Let's say in Zope you have SQLMethod whowhat and SQLMethod whatwhat.  In
your external method you should simply be able to do:

def countWhoWhat(self):
  return len(self.whowhat())

def countWhatWhat(self, class):
  return len(self.whatwhat(class=class))

These should return the result count for each SQLMethod.

Now, I now I can do this using JavaScript on client side, by doing something

MyFunc()

form.submit();

}

So is it possible to do this without JavaScript ?

I never had any problems, but then again, I'm not sure I've ever done this with
index_html, or in quite the way you describe.

Done it lots with calls to SQL methods and other DTML methods, but I don't think
they reference other objects themselves...

Hi all,

I have built a trivial ZClass : CD (from CDProduct, from the guides).

I try to add a DTML Method "render_short".
This method would render the CD Instance on one short line.

My ZClass has simple attributes (artist : string, title : string,
description : text)

I would like to be able to write this simple "render_short" DTML method like
:


Artist : <dtml-var artist>
Title : <dtml-var title>
Descr : <dtml-var description fmt="structured-text" newline_to_br>

But when I insert a <dtml_var myCDInstance> in my index_html, I got a
exception :

Error Type: KeyError
Error Value: artist

There is no typo in my code...
How can I access to my ZClass instance attribute from inside its methods ?


Please help me :)

Olivier

Is this a pure Python question? (Zope External methods
are VERY different from Python methods, that's why I need
to ask.)

If you are talking about pure Python, sure, you can add
class members (data or method) at any time.

-----------------------------
File A.py:

class Chicken:
    def __init__(self, size):
        self.size = size
--------------------------------
File B.py:

import A

def getSize(self):
    return self.size

A.Chicken.getSize = getSize

b = A.Chicken(123)
print b.getSize() # prints 123
--------------------------------

If you are using Zope, you must store your
classes where they can be accessed by
Python. Usually /lib/python/Shared/Local
is a good place, make sure to add the
__init__.py file inside the folder. You
then refer to the class as Shared.Local.Chicken.

What a coincidence.
 I have exactly the same problem. One site with GUF and a CatalogAware
ZClass which silently stops after some time. No errors.

The problem with GUF and DEBUG mode relates to lost filedescriptors.
Someone posted an explanation (maybe a patch too). You might be able to
locate it by doing a search on the list.

Please let me know if you find something out.

I agree. The guides need to be complete, error free, and chock full of
examples.

Hmm. I wasn't aware of the old style syntax, that should definitely be
updated. I also agree that we need to review guides and update examples
to use the latest and simplest techniques. This is especially true for
DTML.

I agree. We do have categories for How-Tos but they are not currently
sorted on Zope.org by category. Probably the categories could be
improved, too.

Again I agree. How-Tos should also provide some feedback system to allow
readers to comment on How-To and point out problems.

Thanks for your excellent ideas!

I'm a little pzzled about :

"objects don't re-import back into the correct place"

I haven't had any trouble exporting / Importing enitre branches. Of course,
I delete the branch to be overwritten first, or at least move, or rename
it. Is that how you're doing this?

XML export may come into play here, since the XML version is parsable. I'm
not aware of any existing Zope tool for dunning a comparison process.

One point that I think is still evolving is a clear set of guidelines
regarding what data is held in Zope, and what should be in other formats,
such as Gadfly. As long as we diligently keep DTML doing templating, and
avoid mixing tabular data and static content in with ZODB objects, it
should be fairly straightforward to do Zope Exports of the Zope Framework,
and file copies, or native exports of data in other "backends".

Mailman has no "global" username/password directory -- every email
address in every list has a password associated with it, that's all.
Known design flaw, and Barry Warsaw (the Mailman maintainer) has
threatened to fix it.

I think this *might* fix the problem you guys are having.  Although we
aren't using GUF or CatalogAware objects, we discovered this on a system
that was under pretty heavy load.

Hello,

I search for a way to implement an URL-Traverse like the SQL-Product. I
need some key/value-pairs for a method and won't use an URL-get like
.../my_method?key=value. Instead a .../my_method/key/value or

Has someone a small code-snipet or something like that which explains the

Hello WorldPilot Users,

There's a new WorldPilot 1.0.3 maintenance release available,
that addresses some of the interoperability issues.
Check out
http://www.worldpilot.org
or
ftp://demo.worldpilot.com/pub/worldpilot/worldpilot-release-1.0.3.tar 


Calendar Problems:
For everybody who had Timezone troubles with the WorldPilot
Calendar, this release should hopefully work for you now.

Please send us your positive or negative feedback to
mailto:feedback@worldpilot.org
so that we know if it now works around the globe :-)


UW IMAP users:
And for all the (UW-) IMAP users there is now a IMAPHACK.py 
file located in the WorldPilot Product directory. Here you
can set the Base IMAP directory (e.g. Mail or INBOX) and
you can choose to only list subscribed folders (but you'll currently
need to subscribe them with a seperate client).

Thanks for all the tips and suggestions! I hope WorldPilot will 
soon operate with most of the remaining other IMAP servers, too.
We're still working on some of those other tracebacks that got
sent in.

Cheers,
Ryan

That's OK. Please do the experiment yourself, it
only takes 3 minutes or less to verify it. You
don't need to trust my words. Trust the result
you see with your own eyes. :)

A good many people in the list have said this
repeatedly: try it first, before posting. I think
it's a little bit too much to ask everyone to
do that every time, but this is a responsible
mailing list and not some flame-loaded newsgroup.
So, when it takes only a few minutes to confirm
something simple, why not try it first?

regards,

Hung Jung

Message-ID: <20000309142919.D183689@isc.upenn.edu>

hi: I'm trying to use the BasicAuth example in the "XML-RPC How To"

http://www.zope.org/Members/Amos/XML-RPC


I keep getting the Zope error when creaing the External Method:

Zope has encountered an error while publishing this resource. 

            Error Type: SyntaxError
            Error Value: invalid syntax

--------

I've just cut and pasted this from the webpage, only removed extra padding spaces, and spliced the one big
line back together:
 h.putheader("AUTHORIZATION", "Basic %s" % string.replace(encodestring("%s:%s" % (self.username,
self.password)),"\012", ""))



The code defines a class and a def:


---------------
class BasicAuthTransport(xmlrpclib.Transport):
    def __init__(self, username=xxxx, password=xxxx):
        self.username=username
        self.password=password

    def request(self, host, handler, request_body):
        # issue XML-RPC request

----------------
In the Add External method page, where you enter in the Function name I've tried:

request
BasicAuthTransport
BasicAuthTransport.request
request.BasicAuthTransport

Which is the right one? it want's the Function 'request', right?

So, the syntax error must be something in the script.

Any help would be appreciated.

You *can* actually get Python to crash if you're intentionally mean to
it.  All the ways I know of involve tricking it into blowing the C
stack, like:

	class C:
	    pass

	C.__init__ = C; C()

Not that you could expect that construct to do anything useful anyway;
you wouldn't ever see code like that in an application.

You have to go out of your way doing really bizarre stuff get it to crash.
It's very stable otherwise.  :-)

First of all, what you want can be done, but it is not that easy.  There
are a couple problems with your design goal, some Zope's, some yours. 
Luckily, the alternative is *very* easy ('very' being a relative term
here, basicly it means you don't have to re-engineer Zope).

You probably know this, but when Zope is tooling down through objects is
traverses them according to various rules.  First, it does something
special (we'll get to that), then it tries to find the next object in
line by just seeing if the next object is a subobject of the current
(getattr).  If that fails it tries to get the next objects as a sub-item
of the current (getitem).  If that fails, then it gives you a 404
telling you it couldn't find the next element in the URL you provided
(you being the client).

The special thing it does is it calls __bobo_traverse__.  This is a
special method.  So you override the root level folder's
__bobo_traverse__ to see if your 'virtual folder' is a user and then
proceed from there.  This is the problem: 1) You can't override the root
level folder, because it's not a folder, really, it's the entire Zope
application and 2) we override it allready so we beat you to it.

Further, although simple, I think you will come to hate having all of
your users in your root folder namespace.  Generally, you want to keep
this namespace as unclutered as possible for many reasons.  One good
reason is that everything in the root folder is acquireable by
everything else, so it's 'prime real estate' in Zope.  Another is what
if one of your users wants to be named index_html?  Or rss?  Your
__bobo_traverse__ method will either have to know all the special names
you want priority on and do the users second, or whatever.  Complex. 
Prone to error.

What you really want is this:

mysite.com/Users/Fred/rss

So you need a special object, in this case instanciated with the id
'Users', that takes the next argument in line as a key into a database,
and doesn't break acquisition paths along the way and lets you do this
fancy URL manipulation.  This special object can have a much simpler
__bobo_traverse__ method, because it's not also trying to deal with
other objects in the same namespace, the 'Users' namespace is dedicated
solely to serving these virtual path elements.  This special object
should also be very generic, not database specific, and should be
programmable directly with various SQL code to execute the query you
want.

This special object allready exists and does everthing you want to do,
it's called a ZSQL Method.  ZSQL Methods can accept arguments in the
URL, and maintain acquisition so you can apply results to 'higher'
objects.  In fact, you can even chain ZSQL methods together to do
multiple database look ups.  Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.

Nifty eh?

Exactly, absolute_url tools up through the various aq_inner wrappers to

Hi Andy,

In my MySQLdb directory, the Setup.in file contains the following:

_mysql
_mysqlmodule.c -L/usr/local/lib/mysql -I/usr/local/include/mysql -lmysqlclie
nt

Note that this does NOT point to the location of the Python.h file, as you
suggested it should (below)

I've just finished recompiling and installing Python, Python-devel, MySQL,
MySQL-devel; after each step, I tried to run the build.py script and each
time I get the following error:

 Traceback (innermost last):
    File "build.py", line 14, in ?
      import MySQLdb
    File "MySQLdb.py", line 19, in ?
      from _mysql inport *
  ImportError: ./_mysqlmodule.so: undefined symbol: Py_InitModule3

I even tried installing just MySQLDA and that failed, too.

<EXTREME FRUSTRATION>All I want is to be able to connect to a MySQL DB from
Zope.</EXTREME FRUSTRATION>

Any assistance is greatly appreciated!

Eric.

<guess>

You must still use medusa (ZServer, in this case) even if you want to
use PCGI (which is what Zap uses).  ZServer listens to many protocols,
like HTTP, FTP, and PCGI.  If you don't use medusa, PCGI will try to
fire up Zope the OLD way, and it will probably work but it's not the
right way.  The problem is, now your process environment has the wrong
LD_LIBRARY_PATH (and a whole slew of other problems related to running
Zope the old way, like no concurrency) and cannot find your Oracle
dynamic libraries.

Run ZServer first.  Then Zap.  Then it should work.

Yes, the Catalog can be used programatically from DTML and Python.  You
will have to implement your own parser (look at the standard htmllib in
python) that feeds the parsed attributes into the Catalog.

Does it do it out of the box?  No.

I'm sure this is simpler than I'm making it out to be, but here goes...

I'm looking at using SquishDot as a 'home page' for our Intranet, but can't
seem to make its index_html show up as the default document.  What I'd like
is for a user to be able to point his or her browser at
"http://www.mysite.com" and get SquishDot, outisde of setting up a redirect.
What's the easiest way to do this?

I looked at this once and my mind got lost in a sea of table tags.  If
you pin it down conclusivly as a bug, we'll fix it.  But it never
happens on Exploder, and I haven't seen it on Mozilla yet, so I'm

Yeah, and blue people are dumber than green people and orange people are

The perfect counter argument is.  "Prove it."  If this person asks *you*
to prove it, show them the Lawrence Livermore National Labs, the
mems-exchange (all multi-million $+ scientific establishments), Jon
Udell articles, etc etc.  There is a mountain of evidence on your side

Message-ID: <NDBBKGBPJMFODAAFNMKEOEANCAAA.mduvall_22030@yahoo.com>

I think my Zope is working with IIS, but some of the icons in the Management
screen can't be found.

For example, the Control Panel icon is fine:
http://localhost/scripts/zope.pcgi/p_/ControlPanel_icon is indeed there.
This looks like an object reference, right?

The Folder Icon:
http://localhost/scripts/zope.pcgi/misc_/OFSP/Folder_icon.gif , however, is
not. The same is true for the User Folder and DTML Method gifs (and a few
others). In the Zope install, the gifs are in the
root\lib\python\Products\OFSP\images folder.

I'd welcome any suggestions. It's a minor problem, but it's a bit of an
eyesore. Thank you!

Regards,
Mitch Duvall
mduvall@webversant.com

P.S. There was a thread about Zope / IIS last month. I was in a similar
situation in which all I could see when I got to step 6 in Brian Hooper's
how-to was the "Welcome to Zope" page. The change that got me into the
Management screen and logged on was to use the default 401.5 error message
for IIS' "Default Web Site". My thanks to all who've helped out.

Not without javascript, clicking on a lick causes a GET.  Clicking on a
form button causes a POST.  I could be wrong, but I'm pretty certain
that's the convention.

Subject: [Zope] ZClass, Base Classes and logic (QUEST)
Message-ID: <00030915401200.06239@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

Most of the time when someone complains about DTML syntax or the learning curve
and so on, the answer is we should code our logic in python if we know this
language. That's what I am trying to do because I love Python.

However, many times I don't know how to import my logic in Zope. 

example:

I wrote a very simple module MyTest.py:
##################################
class SuperClass:
	def __init__(self):
		self.a='This is a in SuperClass'

class MyClass(SuperClass):
	def __init__(self):
		SuperClass.__init__(self)
		self.b='This is b in Myclass'
##################################
In the python interpreter I do the following things:
>>>import MyTest
>>>import MyTest.MyClass
>>>t=MyTest.MyClass.MyClass()
>>>t.a
'This is a in SuperClass'
>>>t.b
'This is b in Myclass'

That's what I expected. Now I intall the package in zope.  I make a ZClass which
only Base class in MyClass. Its metatype is MyClassClass, so it appears on the
popup menu near the Add button.

But when I try to add an instance I get the following message:

Error Type: TypeError
          Error Value: unbound method must be called with class instance 1st
          argument

I guess that the problem is the line
	SuperClass.__init__(self)

==>however I don't understand why it works fine with the python interpreter and
why not in Zope.

Others behaviors of Zope:
suppose i add the following line in the MyClass __init__ function:
self.d='I am d'

No problem when I run it with the interpreter:
	>>>t.d
	'I am d'

In zope:
	<dtml-var "MyClassInstance.d"> 
renders:
	Error Type: AttributeError
          	Error Value: d

I get the right value of d only with the new instances of MyClass. On the other
hand if MyClass has a property sheet, all the instances are updated if change
the property sheet.

==>So again, why these differences in the behavior of ZClass instances depending
of which part we modify (the python Base Class or the Zope ZClass)?

I really love Zope but I prefer code in python. However I hit often the wall
when I try to put the pieces together. I think that speaking about
documentation : clear API docs would be, for me the most important.
What behavior could I expect from the differents parts of Zope. 

Example of docs I find useful with other 'languages':
Python Library Reference
Java API documentation

What's the traceback embedded in the HTML source of the error page?

It will point you directly to where the syntax error is.

Nope -- that doesn't do it.  It does raise a lot more questions,
though.  :-(

Recap: I'm working in a near-fresh Zope 2.1.4 installation.
Everything's in the root folder.  Two objects of interest:

  my_dtml_meth -
    a DTML method that shows the document title, ID, etc.  (because I'm
    curious); the title for this object is "Test DTML Method"

  my_xm -
    an external method that does nothing except attempt to set the
    document title and call my_dtml_meth; the title for this object is
    "External Method: Call DTML Method"

The code has changed a bit since my last post, so here we go again.
Here's my_dtml_meth (the DTML Method):

  <dtml-var standard_html_header>
  id:             <b><dtml-var id></b><br>
  title:          <b><dtml-var title></b><br>
  document_title: <b><dtml-var document_title></b><br>
  document_id:    <b><dtml-var document_id></b><br>
  title_or_id:    <b><dtml-var title_or_id></b><br>
  title_and_id:   <b><dtml-var title_and_id></b><br>
  <dtml-var standard_html_footer>

And here's my_xm (the external method that calls my_dtml_meth):

  def my_xm (self, REQUEST=None, RESPONSE=None):
      RESPONSE.setHeader ('Title', "Title from External Method (try 1)")
      REQUEST.set ('title', "Title from External Method (try 2)")
      return self.my_dtml_meth (self, REQUEST, RESPONSE)

Note that I'm trying two attempts to set the title; my original guess
based on reading the HTTPResponse code, and Michel's suggestion.

Here's what happens when I call these things.  First, my_dtml_meth, as
rendered in Netscape:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Ie. it's possible to get the object's title using "document_title" --
but the standard_html_header uses "title", so my browser's window
advertises this document as "Zope".  Ugh.  Guess I could fix
standard_html_header, but why does it work this way?

Now I call my_xm, hoping against hope that it will override the title of
my_dtml_meth; here's what I get:

  id: 
  title: Zope
  document_title: Test DTML Method
  document_id: my_dtml_meth
  title_or_id: Zope
  title_and_id: Zope ()

Hmmm... identical.  Ie. neither attempt to set the title in my_xm had
any affect whatsoever.  In fact, I just used a command-line HTTP client
to diff the headers and body, and they compare byte-for-byte.

So: no dice.  Better ideas, anyone?

(I think I've learned enough to solve my problem, though: use
document_title rather than title in standard_html_header, and make sure
the DTML method in question has a meaningful title.  But I'm still
curious why things work the way they do.)

Ha, ha!  Silly me...

Internally, my server is known as 'www.waco.ct' and I set up SiteAccess so
that every request containing 'waco' and 'ct' is redirected to the SquishDot
folder.  Of course, this means that I instantly can't get back to the root
folder for any reason.  To fix it, I shut down Zope, removed the SiteAccess
product manually, restarted, and got rid of the offending code.

I offer this as a warning to others interested in SiteAccess--the product
works great, but think a little before you set things up, lest you fall into
the same trap I did.

Thanks. That was the problem. I persevered in my mistake because I saw
'Data.fs' in my zope folder (probably created by my own mistake).

I try to understand the ZODB because i want to process some data in my ZODB
with python. Do you it is the right way to do it?

My main achievement with Zope is part of the MEMS Exchange mentioned by
Michel:

   http://www.mems-exchange.org/z/process/builder/

This is a tool for people to specify the process sequence to fabricate a
MEMS device (= micro-electro-mechanical system, aka micromachine or
microsystem).  They're typically fabricated using the same techniques as
IC fab, but in much more varied ways -- hence the need for people to
specify custom fabrication sequences.  For non-specialists, most of this
tool is meaningless, but it's an interesting demo of how much user
interface you can get away with on the web using something like Zope.

For the record, before we started playing with Zope, I was convinced
that complex user interfaces on the web were all-but-impossible.  Thanks
to Zope, I now believe that complex user interfaces on the web are
merely very difficult.  

We have found no bugs in Python developing this system; we certainly
have our share of gripes with Zope, but I think we've only seen two bugs
that really affected the reliability of our web site.  The first bug was
when Zope 2.1 came out, and we made the mistake of going straight from a
single-threaded, PCGI, Zope 2.0 installation to multi-threaded, FastCGI,
Zope 2.1; things got really flaky.  I think we're now running
single-threaded, PCGI, Zope 2.1.4 and things are peachy.  We really need
to step gingerly back into multi-threaded/FastCGI territory to see how
it behaves.  The other bug was a nasty ref-counting problem deep in the
bowels of mxODBC, so can't really be blamed on Zope.

I've named the python script ba.py.


Is using 'request' proper for the 'Function name?'

If it's the same error we were seeing, then it isn't that Zope crashes,
it hangs, becomes non-responsive.  It's not spinning, it's just sitting
there not answering.  The reason why (in our case) is because of an
uncaptured exception in the medusa code.  Whenever medusa encounters an
uncaptured exception in a thread, it closes it down.  Well, it was
encountering an uncaptured exception in the main listening thread, so it
shut it down... now Zope isn't listening anymore... so it just sits
there.

If you want debug output without using debug mode, add this code to your
start script (reverse the slashes for Win32, of course):

STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE

Debug information will get stored in event.log.

Ok, my syntax error was that I was replacing the username and password with strings and not putting them in

That's fixed.

But I'm still having an error now.

True enough, though I'd have liked to see more, and I'd have liked to
contribute more, too, which is to say, I'd like to contribute at *all*
-- no time for that at the moment, however. Ironically, I'm too busy
using it to improve it.

I find it ironic that JPython is even *slower* than CPython. Curious --
is anybody using it for anything worthwhile?

I'm not disputing the success of these languages. Perl, Python, PHP,
Pike -- they're all quite successful at what they aim to be (*). But
people tend to use languages rather than contributing to their
development. You can't just evolve a language indiscriminantly, which is
why we have Guido and Larry, the benevolent dictators. You can't just
go, "oh, and I added iterated loops today". Every damn little feature
requires at least some kind of ratification process. Languages are much
more susceptible to breaking.

(*) Except possibly Pike. I'm ashamed to say it, but I find myself oddly
attracted to this language, if mostly because of its speed and
interesting resemblance to C. Pike is a good example of "how to make a
powerful language/interpreter system that's also very fast". Pike has
had a type system from the outset, which is a definite edge over Python.

Where?

The type system SIG has a funny intro: "Recently, the types SIG has come
under attack for inactivity, and in response Paul Prescod has offered to
guide the SIG towards accomplishing a single specific goal: to develop
an optional static typing system for Python. The December 1999 archives
of the SIG show the discussion that lead to this decision."

Reading this stuff now. It's interesting. I hope they get it right.
Maybe I'll chip in.

What's interesting about Dylan is that, because it relies on static
information such as type hints and class/method relationships to be
efficient, the developers of Functional Developer (formely Harlequin
Dylan) are facing a design problem related to how they compile programs.
They've actually put all of the various libraries into shared DLLs.
Unfortunately, this means they lose the benefits of the optimizations
that can be made through the use of static compiler information. When
you load up the [latest beta of the] Developer IDE and compile a
program, it consumes a whopping 45MB of RAM. And it's damn slow. The
absence of such optimizations is one reason for this hogging tendency.
So they're planning on providing a "whole program delivery" option
whereby all libraries would be statically linked.

I have several apps where I would rather use Python, but where speed is
so significant that I would either end up writing a lot of the code in
C++ for speed (which is painful due to the lack of integration between
the two languages -- Python classes can't inherit from stuff in the C++
extension, for example).

I also have a database-centric Zope app that causing me headache. The
ZODB is *way* too immature to replace a database right now -- fine for
the kind of stuff that runs on zope.org, not for us. ream

Pardon me for sending off another email in mid-stride. Damn cat :-)

Let me finish the last sentence first: I also have a database-centric
Zope app that causing me headache. The ZODB is *way* too immature to
replace a database right now -- fine for the kind of stuff that runs on
zope.org, not for us. We're actually looking at alternative app servers
and solutions (such as hardwired C++ CGI code) right now. It's a shame,
and I'm fighting it, but we might end up with something like Dynamo.

I don't necessarily say they're _my_ problems, but some people think
they are, and that counts. I don't miss "switch" myself, although I do
miss a kind of enumerated type.

I remember sitting down with Python for the first time create a simple
CGI type thing, and found that I could just do

  def DoSomething(): ...
  def DoSomethingElse(): ...

  DoSomething(eval('Do' + Args['cmd']))

and then call up the CGI using a query string such as
/cgi-bin/foo.py?cmd=Something. Wonderful, and better than any kind of
RTTI.

The list comprehension syntax is cute, but not, I think, so clever.
Perhaps it'll prove to be a nice feature, even a successful one, but
personally I doubt, even with the knowledge in the back of my head of
how this stuff works, that I would instinctively grasp for a
list-comprehension expression as naturally as I grab for, say, a "while"
loop. My head is just not wired that way, and I think the syntax looks
positively alien for Python -- it's not "pythonic".
 
> I don't think you'll see protected members any time soon.

I think Zope's source code is one huge, glowing argument in favour of
having protected members.

I don't particularly take to the idea of a having
mutability/immulatibility property burned into the type itself.

Tuples are immutable, dicts and lists are mutable. Why? Because Guido
says so. Jon Udell, I think it was, has argued that tuples are currently
a redundant element in the language. Why have two kinds of lists? It
just confuses people.

A syntax for declaring the mutability of types would be helpful in
clearing out this mess. For example, you should be able to declare a
dict to be immutable when passed to a certain function call -- ie.,
forcing a copy. Python has no "out" parameter, only "in" parameters that
are mutable depending on the type of the object passed. The syntax I'm
alluding to would effectively give you both "out" and "const"
parameters.

I haven't thought it through. I just think it was potential. Why
shouldn't the translated function refer to other objects? The function
would essentially just constitute native calls to the Py* APIs -- in
effect, a translated function would summarize the runtime calls made by
the interpreter during normal execution. Therefore, non-translated
Python code could just as easily refer to translated code (within a
"translated module", which would be a special object), because the
translator module would construct the necessary proxy object to forward
external calls to the inner code. Or something. ;-)

I'll let you know. ;-)

Thanks Mike,

You are right, root/Users/<usernames> makes more sense than
root/<usernames>.

I looked at what you said, went away and read ZSQL Methods user guide
(again).

Now I'm back.....

>>
 Lets say you had two ZSQL Methods in the
root folder named 'Users' and 'Flavor'.  You can now do:

mysite.com/Users/Fred/Flavor/Cherry/rss

Users traverses 'Fred' as an argument, then *acquires* Flavor, which
applies Cherry as a argument, then acquires rss.
<<

So my Zope folder layout looks like this :

root
   index_html (default)
   Users (SQL method)
   Flavor (SQL method)

I assume I would also need a DTML Document called "rss" because the SQL
methods can't actually deliver any content to the client browser?

So, if you would be so kind, lead me through how Zope works on this call :

mysite.com/Users/Fred/Flavor/Cherry/rss

Zope starts to traverse the call from left-to-right?

finds "Users", its a SQL method which takes an argument, aha! the argument
is "Fred",

[Does Zope now run the Users SQL with that argument?]

ok, what's left : "Flavor", okay, I have a "Flavor" SQL method here and that
takes an argument too, "Cherry" is that argument.

Finally, Zope finds "rss", if this is a DTMLDocument or something "servable"
it runs it and returns it to the client?

If "rss" wasn't there it grabs the index_html page and serves that?

=======

Thanks for your help.

Like many others I suspect, I see Zope through a cloud. Sometimes I see the
outlines of it and it glimmers! But I just can't grasp a picture of the
whole.

Ah yes, I didn't realize it was in an external method.  External methods
mask the exact error information.

Just import ba.py into a python interpreter *without* Zope and it will
tell you where the error is.

I have a page that sometimes gets displayed in a frame

display differently (with a header) when its  not
in a frame.  Is there a way I can do this?

I don't suppose the name of the target frame
gets passed to the browser does it?

Presumably the only way to do this would be
to do it in client-side code and fecth the header
if appropriate and filter it to make it what is
needed.  Or is it?

Calling a method with () is a python convention.  HTTP has no convention
of calling anything, we just use the convention that the query string
(everthing after the ? in a URL) is a list of name=value pairs seperated
by &.  This is per the CGI specification.

I'm getting a weird invalid character error on my ZSQL Method using
ZOracle... If anyone could help, I would appreciate it:

I have a method with the following params:

    id username password firstname lastname title deskphone cellphone
pagerphone emailaddr soffice_id sprdarea_id

And the following query text:

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values
      (<dtml-var id>,
       '<dtml-var username>',
       '<dtml-var password>',
       '<dtml-var firstname>',
       '<dtml-var lastname>',
       '<dtml-var title>',
       '<dtml-var deskphone>',

       '<dtml-var emailaddr>',
       <dtml-var soffice_id>,
       <dtml-var sprdarea_id>);

When I test it with example feild values, it renders the following
error:

    Error, oci.error: (911, 'ORA-00911: invalid character\012')

With this SQL Used (which if you try in SQL*Plus, is perfectly valid):

    insert into suser
      (id, username, password, firstname, lastname,
       title, deskphone, cellphone, pagerphone,
       emailaddr, soffice_id, sprdarea_id)
    values

Any words of wisdom?

For the sake of this discussion, yes.

They return query results, which are a sequence of record objects.

Yes.

If you tell it to, check out the 'Advanced' tab on ZSQL Methods. 
(First, don't forget to specify one argument to the method or else you
won't see what I'm talking about).
 
> ok, what's left : "Flavor", okay, I have a "Flavor" SQL method here and that

First it finds Flavor, then it traversed into Flavor, then Flavor find
the next element as its argument (once again, if you tell it to).  So
essentially the answer is yes.

Yes.

If rss wasn't there and it was in your URL then you would get a 404
NotFoundError.  If 'Cherry' is your last argument then yes, it would
acquire the first 'index_html' object that it found, which in this case
is the one in the root folder.

Greetings,


In my experience, to count the size of an array in ZOPE does not require an
external method, simply "_.len(sqlQuery())".  I use this myself in a few places.

I won't try to guess your reasons for not getting sql to count, but surely it
would be by far the simplest way?

Thank you Michel,

After trying your suggestion I came upon this problem:

A white screen with "No Items were specified!" at the address:

   ../BOStorage/manage_delObjects?id=20000428164227

(BOStorage is where the objects are stored and I verified the id#
20000428164227)

Thanks.

Can they do that? How? Something funny in the license agreement?

Subject: [Zope] Use only part of a list sequence? or External Method to Insert ZSQL?
Message-ID: <019301bf8a24$162d8180$5e577e86@jmu.edu>

To all Zopists,

<background>
I have a form that has several dynamically generated options from a MySQL
database.  I have each option using a hard-coded array like
name="mylist[0]", name="mylist[1]", etc..., and keep the value blank unless
selection is made.  Everything is working fine.  In the next page, I will
insert the Authenticated_user as the userid, and another field into a table
in the MySQL database.  When I get to the next page, I have:
...
<dtml-in mylist>
    <dtml-if "_['sequence-item'] != ''">
      <dtml-if "countuser(`AUTHENTICATED_USER`) < 6">  ##countuser counts
user in table
                 will be inserted into tabel here...
      </dtml-if>
    </dtml-if>
</dtml-in>
...
People are only allowed to have 5 entries in the table.
</background>

Here are my questions:
1.  Should I use an External Method that accesses a ZSQL Method to insert
the fields into the table?
(please give me an example of this, it sounds interesting...)

2.  Is there a way to only use the first 5 listings of the sequence?  Maybe
save into another list, then go directly to a ZSQL method insert?

3.  Should I just quit and go home?
:o)

Any help would be greatly appreciated.

   No, it takes a string. Try:

<dtml-call "RESPONSE.redirect('/target?myvariable=xyz')">

I would like to redirect a user based upon a variable.

<dtml-call "RESPONSE.redirect(/target?myvariable=xyz)">

raises a syntax error.  Does the redirect command only take literals?

redirect takes string.  The correct syntax would be:

<dtml-call "RESPONSE.redirect('/target?myvariable=%s' % xyz)">

Remember, once inside quotes ("") you're writing Python code.

Thanks again Mike.

So my final (I think, for now) question is this :

The whole point of Zope is to get a result back so the URL :

mysite.com/Users/Fred/Flavor/Cherry/rss

is (the way we have discussed it) really a way of saying : "I want an "rss"
document containing information related to User=Fred, Flavor=Cherry.

So in order to get my content out I just have to do some things with
<dtml-with Users> and <dtml-with Flavor> in my "rss" document? (because
these SQLMethods will already have been set up & run as part of the URL
traversal and are ready to give me data?)

I appreciate your patience,

- Ian Sparks.

That would be the last semi-colon ";". Remove it and use in the ZSQL method.
Additionally, instead of <dtml-var  ...>, you might want to consider using
<dtml-sqlvar >, which will assist you in properly SQLising the data.

Subject: [Zope] No resposne to valid HTTP requests.
Message-ID: <00031011262501.26896@localhost.localdomain>

Greetings,


So, I got into work this morning, ready for another day of zoping, only to find
my server not quite responding properly.  When i went to the manage screen, the
tree frame didn't fill, but the right-hand frame was fine.

Hmm, thought I.  Oh well... i can work without it.  So, I clicked on the folder
for todays work and..... 

nothing....


no response at all, not ever a timeout!

Talk to the network admin, we both kick about... and it seems that the ZOPE
server will respond correctly to invalid GET requests, but just freeze on valid
requests.

Further testing shows that it's ONLY when i try to use the management screens. 
The only change in my system recently has been upgrading from NS4.7 to NS4.72.

It's RedHat 6.1, and Zope 2.1.4.

Any idea?

Yeah, that would be very helpful.

As a Zope Newbie, who's developed lots of database stuff in PHP and Perl, I 
am unclear on whether I'm "supposed to" try to make everything an object in 
ZODB.

Say I'm making a repository of documents, like articles or e-mail messages, 
and I expect to end up with 100s of thousands of those, should I 
confidently work on making them all Zope objects, or should I stick with 
mySQL records and/or files in the file system, like I normally would?

As a follow up... i checked another site of mine, and it is now showing

The whole server seems to have locked up.

You don't even have to work that hard, consider what happens:

Let's say that your Users method queries a table that contains two
columns, name and title.  Primary key is 'name'.

Your second method queries a table that contains two columns, flavor and
size.  Primary key is 'flavor'.

Users method is called with 'Fred' as argument, this returns a single
record object.

ZPublisher then tries to find 'Flavor' on that record object, it doesn't
have such an attribute, but it CAN acquire it, so it does.  It discovers
that it is a SQL method and calls that method, *in the context of the
first record object* (keep that in mind...).

The second method is called with 'Cherry' as a argument.  It returns a
single record object.  Now, ZPublisher tries to find 'rss' in that
record object and fails, but it DOES acquire it, *in the context of the
second record object which was found in the context of the first*.

Now you are in the rss method, but you are also in the context of the
second and first result objects, in that order.  So in your method, just
say:

Hi my name is <dtml-var name>.     I'm acquired from the first result
object.
My title is <dtml-var title>.      I'm acquired from the first result
object.
The flavor was <dtml-var flavor>.  I'm acquired from the second result
object.
The size was <dtml-var size>.      I'm acquired from the second result
object.

Note that if a subsequent record object has a column name identical to
that of a preceding record object, the subsequent one is acquired
first.  This means that subsequent results can 'refine' previous ones.

Note that this concept of accessing one object in the context of another
is what is called Acquisition and all Zope objects support it, not just
ZSQL Methods.

--------------------------------------------------

(1) It should work. I have tested it. Nothing
    special is required for the __init__.py file.

(2) Make sure that you have an __init__.py file
    inside your lib/python/Shared/Local folder.
    This file can be empty. Or you can provide
    some __doc__ and __version__ string like
    Digicool people do. But it really can be
    an empty file.

(3) Inside that folder, create a file Chicken.py,
    which contains the following three lines:

    class Chicken:
        def __init__(self, size):
           self.size = size

(4) This python file will not compile automatically.
    It will only be compiled when it is imported
    by some other Zope modules.

(5) To test what you want: create an external method.
    In the folder Extensions inside your Zope root
    (if you don't have an Extensions folder, you
    have to create one first), create a file Test.py
    containing the following lines:

    import Shared.Local.Chicken

    def getSize(self):
        return self.size

    def test(self):
        Shared.Local.Chicken.Chicken.getSize = getSize
        a = Shared.Local.Chicken.Chicken(123)
        return a.getSize()

(6) Go to Zope management screen. Restart Zope.
    (Or shut it down and restart it manually.)

(7) Create an external method with 'Id' = test,
    'Function name' = test, Python module file = Test
    and click on the 'Edit' button, then click on the
    'OK' button. If you don't know what an external
    method is, you've got bigger problems than I
    thought. :)

(8) Hit the 'Try It' tab.

Done! now you can use the external method inside
your other DTML documents/methods. For instance,
you can have a mytest_dtml method with the following
lines:

<dtml-var standard_html_header>
<dtml-var "test()">
<dtml-var standard_html_footer>

and it will print the number 123 when you view it.

I shouldn't have treated you like a 3-year old.
But I guess making instructions as clearly as
possible eliminates unnecessary confusions. :)
We've all been newbies once.

This really isn't enough information for us to do anything except
console you.  Can you do some more investigation?  Try shutting down
your Zope and going to the lib/python directory and then doing this:

bash$ python
Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [GCC 2.7.2.3] on linux2
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import ZPublisher, Zope
>>> ZPublisher.Zope('')

Does that return your top level ('yoursite.org/') content?

Are you using some non-standard modules like SiteAccess?

Yes, I am using SiteAccess.  However, this site has been working fine for some
weeks now.  The site works until you go to the management screens.

Also, an older site of mine (running on Zope 2.1.2) has also shown the same
problem, which started last night.

Two seperate sites showing the same problems at the same time?  Coincidence? 
Not likely.

No you are doing it the right way and it should work fine.

Is there an error and a traceback?

Ha! This must be the most innocent message in a long time. :)

BookS on Zope? Good titleS? Get THEM? Oh boy, oh boy.

There is ZERO book on Zope. But DC people neither confirms
nor denies book deals, this is what I last heard.

All what I need to know in Zope I learned it from the
net, just like everyone else. :) The myriads of loose docs
plus the mailing list does the job. Poorly, but it does
the job.

A good Python book is a must, though, when you want
to get into more advanced features of Zope. O'Reilly's
"Learning Python" by Mark Lutz and David Ascher is
a good bet, well... maybe the only bet. :)

No error or traceback.  It takes me to the "manage_test" page and I can put
the number in manually, and it works.  The crazy thing is, I can force-feed
it the manage_test, like:

<a href="/queries/SearchResultPage/manage_test?theid=<dtml-var
the_id>">link</a>

and the test comes up ok. I don't have a clue on this one...

There are no books on Zope yet.  Mike released a plan some time ago about a
book that he was working on w/ O'Reily.  Maybe he'll give us some new info
:)

I suggest "Learning Python" to get more acquainted with python and then
using the mailing lists and stuff on Zope.org for now.

Later, Nick

Mike,

The problem was on my end.  I was referencing the method instead of the
report page.  Ok, I admit, oops on my part.  Sorry for the trouble. Been
here at work to long.....

I think it's time to go home....it can wait 'till 'morrow....

Thanks for helping my step-back and think alittle.

I don't know what it is, but something had to happen, unless there is
some mysterious kill-your-Zope-on-Mar-8 virus going around.  The one
upgrade to Netscape is unlikely.  But *something* had to happen to both
boxes.  They may be related, they may very well be coincidences, but
neither of them manifested themselves by themselves, that is even more
unlikely.

Greetings Thomas and welcome to the Zope list.

One place you may want to start is WorldPilot (http://www.worldpilot.org).
WorldPilot is a will handle some of your needs. Its a web based PIM with
e-mail, scheduling, address book, and to-do list functions.

What type of document administration are you looking to do? I have some
Notes/Domino experience and if that is your reference point I may be able to
help you find answers based on Notes style solutions.

Thanks a lot for this info...  Well, in that case, I have to be content

No nothing. Really weird. I have actually tried on a Zope instance that
was accessed only by one person and still it will silently stop after some
time. Nothing related to heavy load ...


Could be related to GUF as I was getting some exceptions from GUF but they
were uncorrelated in time.

Thanks a lot Nick

I haven't tried out your suggestions yet but I *hope* they point to the
problem. You write nevertheless that in your case Zope hangs, whereas in
my case the process just dies silently and doesn't even trigger the
manager to restart it. I will try my own supervisor on it and see how it
behaves.

I don't think you need to really get out of your way to crash python. For
someone discovering __getattr__ for the first time and wanting to do some
simple delegation ...

class A:
    def __init__(self):
        self.a=[]
    def __getattr__(self,key):
        if hasattr(self.a,key):
            return getattr(self.a,key)
        else:
            return getattr(self,key)

Wrong but not really bizzare IMO

The story so far...


Well, the second site which appeared to be showing the same problems... isn't. 
It is now working fine.  So, I'm left with just the first site, which is
currently the more important site.

I can traverse normally, until i try to enter a management view.  Then, the
frames arrive, and, upon first attempt, /manage will work, except for the left
frame.  After that, no manage screens work at all.

I do have SiteAccess, but even with __no_before_traverse__, the same problem
occurs.  I can go back to regular pages, and all is fine.

Have a better one,

Please do not try to match the start tag and end tag again and again in
zope.

Please come to see the http://zope.org/Members/kentsin

and get the root.zexp for evaluation.

This is a set of method/attributes which will publish the folder's index_htm
document

The methods will generate the doctype, stylesheet, javascript, rdf for the
document.

It can be configure by setting certain attributes.

Hope this will get into the zope mainstream.

Rgs,

Your problem definitely seems to be coming from
SiteAccess. Evan should be able to help you out.

What you may want to do first is to disable
SiteAccess first. Something like:

http://www.whatever.com/__no_before_traverse__/path/to/rule/manage_main'

Then go to the management screen and UNDO that very last thing
that causes SiteAccess to get into infinite loop. If Zope is
not problem, do you have Apache re-write rules somewhere
modifying your URLs?

The first time I used SiteAccess was also my last time.
It was so freaking scary to have a hang-up situation where
you cannot do anything except cry in desperation. :)
Several people have reported problems with SiteAccess.
It's not that I don't think SiteAccess is great: its
concept is great, just that I don't ever want to get
into this kind of scary situation again. :) I am waiting
another few months before I get more reliable version
of SiteAccess or its equivalent in Zope. And no, thanks,
I won't be a guinea pig to reproduce the bug. :)

Subject: [Zope] Zope + Coda = Client Side Zope?
Message-ID: <00030922411300.00635@viking>

Some of the dsicussions in the Client Side Zope thread got me to thinking about
an article I read in Linux Journal sometime ago on the Coda file system. As
luck would have I can't seem to find that issue. Most of the information
contained in that article (now over a year old) can be found in updated form at
http://www.coda.cs.cmu.edu/ . 

For those who've not heard of coda its a distributed filesystem that supports a
variety of the features, including disconnected operation and replication among
multiple servers, that were mentioned in the previous thread. 

I will admit to knowing only the very surface information about coda and throw
this to the list for anyone who has actually used it. Also do any of the DC
folks think that a data store centered around a coda type fs would be doable?
I've been intrigued by coda since I first read the article this may be the
reason to explore further.

Any other thoughts on this?

(I read your post and understand you have this working now)

Just wanted to mention there is another 'shorthand' way:

<a href="/queries/SearchResultPage?theid=&dtml-the_id;">link</a>

A little more compact than the one with <>s.

Server is still up, but I'm wondering if these channels reopen or if
they all close if that's what stops the server?

I can see how this exception is getting left unhandled in the medusa
code, so I'm going to try and catch it and startup the server again.

Greetings...


After trying constructing an entirely NEW zope install, and winding up with not
being able to import the backup of my site, I decided to reboot.

Strangely, everything is working again.

Oh well... at least i've learned some more about the innards of Zope.

Absolutly, but in this case you can just use FileStorage, since coda is
a filesystem.

I attended the Coda session at last year's Linux Expo.  There, the
professor in charge of the project gave a very clear explanation of coda
and how it works.

Useful results with Zope should be immediate, Simply store your Data.fs
file on a filesystem that is replicated by Coda.

There is a more interesting application however, and that is
implementing the actual coda protocols themsleves into a sort of
ReplicatedStorage (I'm not positive if that is the best way to slice the
pie, but it's an idea).  Another idea is to roll a similar or identical
protocol into ZEO, so that not only are Storage Clients and Storage
Server are distributed in a parent/child relationship, but also that
Storage Servers can be distributed in a peer relationship that replicate
each other to provide failover and replication.

Interesting stuff in any case.  I'd really like to hear about someone
who has a success story with Code and Zope using just it's filesystem
capabilities.

Subject: [Zope] WorldPilot Acquisition?
Message-ID: <CC59868A0A76D311B1F50090277B321C1F31BA@VRTMAIL>

I've been mucking around trying to get Acquisition to work with WorldPilot
objects (I want to define methods/documents that can query WorldPilot's
"normal" objects (Events, Address Cards, Notes, Todos, etceteras), and the
collections of the same.  So far no luck (I don't really understand
everything going on under the covers of either Zope _or_ WorldPilot, so I'm
not likely applying pressure at the right points).  I've been adding
Acquisition.Implicit to the hierarchies of just about every object with no
luck so far.

Does anyone have ideas on how to go forward?  Could I alter the "normal"
objects in some way to make them accessible at a higher-level (for example,
if I could get at the objects in a flat collection, I could run my queries
against them, using their types to sort into virtual collections).

I suppose, in a pinch, I could just read the local files and construct a
query against them, but that seems... well, too incredibly hacky.
Incidentally, why does WP use all these custom storage mechanisms?  The
actual objects don't seem too complex, and the interface doesn't _seem_ like
it would require the support.

Ideas appreciated,
Mike

Um, no. Since the code that defines 'layout.table' is also available and
editable, (just like any other object).
So you can not only code the specific header you want into the object, but also
create a parameter which can be used like so:

 <dtml-var object="layout.table">
   <param name="datasource" value="get_above_age">
   <param name="columns" value="Name,Age">
   <param name="table_tagattrs" value=" border=0 bgcolor=green">
 </dtml-var>

I learnt you're doing something similar (from Rik). I have to look at it.

What I'm suggesting is that instead of having to create a product every time
you want a higher level object, we could have a framework so that you could
just create an object that does it. The goal would be to make it easy for
everyone to code their own component objects (or templates, or patterns,
or whatever)

Another thing I would like is that people start looking at 'documents'
differently. Instead of 'my_element_header' and 'my_element_footer', people
think of 'my_element' which takes one or more parameters. (Please don't flame
me, it's Paul who started all this :-)

I guess not. The problem I  have fits the description, but I don't use GUF.
I have the impression though it has to do with busy interactions with a
Gadfly database. Platform: Windows NT, Zope 2.0.1.

Message-ID: <38C8CAC9.C45A5056@nipltd.com>

Just an idea, but if you want to see if it's a bug, or 'non-standard' html
problem in Zope, try copying the 'view source' html of the tree into an html
document and editing it in Dreamweaver.

Dreamweaver seems very good at finding html problems, and you can run tests to
see if any browsers aren't going to like it.

Hope this helps...

Subject: [Zope] trees, hypernews and frames
Message-ID: <38C8C8E0.AB71B295@open.ac.uk>

Sorry, this is involved and takes a lot of words to explain.

I'm building a zope site which also serves HyperNews
discussions.  Apache and Zserver are working well together.

What I have is a tree widget iterating over a folder,
some of whose elements are treated as hyperlinks to hypernews
discussions.  Base articles for discussions are in the
contents of the zope items so .... when  you click
on an element in the tree it follows a link to hypernews
and the hypernews fetches the contents of the "same
item" you just clicked on.  This is a roundabout
way but the only way I know to keep my hypernews headers
and stuff in zope It does all work well but....

My first implementation had a two column table with
the tree on the left and the particular discussion on the
right.  This worked well logically but wasn't too visually
appealing because as you expanded/collapsed tree branches
everything moved around on the page.  So I re-organised
it to use frames - a header frame, then two columns
(tree in one, discussion in the other) and a footer
and this works very well.

My problem is now this - except for the top one
the frames on the page do not include 
what in the former implementation was the header (i.e.
the fancy bit at the top that gives context and doesn't move).
Now its possible and common to access the hypernews discussions
without coming in through the zope home page with the tree
widget.  It is common to do so because when hypernews sends
email it puts a hyperlink to the item in the email which
does just that.  When this hyperlink is followed the page is
fetched from zope but of course the fancy header isn't there.
Since its no longer displayed inside the frameset the
header needs to be displayed as well but isn't.

That's the crunch.  How to get the fancy header served
when its displayed outside the frameset but not served
when its inside.  If it were all in zope then this could
be done by passing a variable value so the page could
know how it was called but hypernews does not pass on
anything like this when it fetches content from other
servers.

Anyone think of a way round this?

Please copy replies to
a.k.heath@open.ac.uk
as I take the digest.

The Guides on http://www.zope.org are available for download and can be printed
out, they feel almost like books if you spiral-bind them ;-)

Seriously, though, they are a bit out of date but certainly a very useful for a
beginner. the order I'd recommend:

Zope Content Managers Guide
Zope DTML Guide (more of a reference really...)
ZSQL Guide (if you want stuff out of a DB)
ZClass Guide (this is probably the worst of the guides and I personally didn't
find it very helpful...)

All available from http://www.zope.org/Documentation/Guides

You can easily turn off ZServer's http server but still leave the other
servers.  Or you can turn them all off except for PCGI.  See the usage
documentation in the z2.py file in the Zope top level folder.

Subject: [Zope] Searching in textfiles
Message-ID: <20000310114307.95496.qmail@hotmail.com>

Hi all!

I'm quite new at this whole Zope thing, so I'm probably overlooking 
something quite trivial.
Here's the deal:
I've uploaded some text files into a folder called "Taglines" there are some 
30 files in all. Now for the problem: How do I search the contents of the 
files?
I made a ZCatalog and I know I have to make an index on "something" but I 
can't find what that something is.
Can this be done? And if so: How?

greetings,
Bart Holthuijsen.

Subject: [Zope] REQUEST vraible methods
Message-ID: <38C8E437.3B1D9AC9@nipltd.com>

Hi,

I'm trying to write a SiteAccess Rule to do some simple virtual hosting helping.
Basically, I'd like to have access from http://www.mydomain.com (which is
virtually hosted...) and from http://zope-host.nipltd.com/mydomain (the actual
Zope host) and have all the management views, absolute_url()'s, etc working
properly.

If you just drop a SiteRoot in /mydomain then everything works fine through
http://www.mydomain.com but http://zope-host.nipltd.com/mydomain/manage just
jumps to http://zope-host.nipltd.com/manage. So I'd like to write my own Access
Rule to do this.

Now, the documentation for SiteAccess mentions a few methods of the REQUEST
object that I can't find documentation for. I was wondering where I could find
complete documentation for the REQUEST object, or how I can find out what its
data and method attributes are?

cheers,

Chris

   You don't need AccessRule for this - just path correct SiteRootBASE and
SiteRootPATH environment variables to SiteRoot. Define it differently on
every server, that's all.

Hmmm,

Not sure I get you, and I'm not sure my explanation was clear... ;-)

I'm only dealing with one server, which hosts several sites.
Each site is in its own directory off Zope's root.
eg: http://zope-host.nipltd.com/mydomain

Each of these sites has its own domain name, which is virtually hosted using
Apache as a front end into Zope. 
eg: www.mydomain.com --> http://zope-host.nipltd.com/mydomain

Now, we typically maintain the sites with:
http://zope-host.nipltd.com/manage
and navigate through the links from there.

However, site owners may maintain the site with, for example:
http://www.mydomain.com/manage.

Also, currently, wherever there's an absolute_url() or the like, such as in the
management screens or in Squishdot sites, links are generated as follows when
accessing through www.mydomain.com:
eg: http://www.mydomain.com/mydomain/manage

If you follow these links, they work through the magic of aquisition but,
through following several such links, you can end up with rediculous URLS.
eg: http://www.mydomain.com/mydomain/mydomain/mydomain/mydomain/manage

I think SiteAccess's Site Root's are designed to sort this out. You drop a Site
Root with a path of / into the /mydomain folder.
Unfortunately, this site root also affects access through
http://zope-host.nipltd.com/manage and so if you try and follow the link to
http://zope-host.nipltd.com/mydomain/manage_workspace you in effect get
redirected to http://zope-host.nipltd.com/manage_workspace 'cos the Site Root
strips out the /mydomain.

Also, if you go to http://zope-host.nipltd.com/mydomain/, all the links are
broken for the same reason.

Which is why I want to use an Access Rule instead and make it a little cleverer.

Which is why I'm trying to find out what methods/variables there are in the
REQUEST object, which doesn't appear to be documented very well ;-)

cheers,

Chris

Actually that's not _completely_ true.  The Quick Python book has a
chapter written by Brian Lloyd and Amos Latteier on what used to be
Bobo.  It's still a useful intro into the idea of object publishing with
Zope.

   Do not pass any SiteRoot* variables in this domain and pass both in
www.mydomain.com.

   SiteRootBASE => http://www.mydomain.com
   SiteRootPATH => /

That should do all tricks you want.

Richard,

The equality check on AUTHENTICATED_USER will always fail because your
comparing an object with a string.

You need soemthiong more like :

<dtml-if expr="AUTHENTICATED_USER.getUserName()=='zope'">

One tiny datapoint.

I set up a small Engineering Change Request system w/ zope and
PostgreSQL 6 months ago.  It has been running flawlessly [1] ever since.
Machine uptimes are in the mid-2 digits (i.e. about every 2 months we
have to rearrange things in the lab).  Note this is a very low load
application.

As for perl/python stability, you could go back and see how often
new releases come out and use that as an argument.

Okay, I think I'm starting to understand more, btu I'm still not quite there yet
;-)

When you say 'pass any siteroot variables' what do you mean?

Do you mean pass them from Apache?
Do you mean set them as properties somewhere?
or something else....

Well there goes this weekend. ;-) I've grabbed the Postscript copies of some of
the coda documentation and I think I'll attempt to set something up this
weekend if I have a chance. My "lab" setup includes a Linux server, a Linux
workstation, and a Windows 95 workstation, so I'll be able to check so measure
of "cross-platform-ness".

The idea of a ReplicatedStorage mechanism is what I was (mis)firing at with the
original question on feasability.  As I have stated before on this list some of
my background is Lotus Domino/Notes and this could bring Zope close to some
functionality of a Notes Client/Domino Server interaction. (I won't bore the
list with details if anybody wants some I'll be glad to do it outside the
bandwidth of the list, unless a lot people want it :-)

It looks fine, so far and i downloaded it.
I'm not sure if i understand the Workgroup-sharing correctly - can
different users participate at the same Address-book or Calendar?
I mean does it support a shared calendar for several people?

If yes, this Product is my way to go and Zope and WorldPilot will get another

I'm not entirely sure here - the client wants something that would be

to use LINUX and Zope. As i can tell, Notes/Domino may be exactly what

   Exactly this. How do you access Zope from Apache? Proxy, FastCGI or
PCGI? They all have different methods to pass vars (and I afraid proxy
doesn't have such way).

   Properties will be used for all domains, that why I said set path
property empty in SiteRoot.

You can set any terms you like in your use license. Whether they are
enforcable in a civil court is a separate question. For example, all
through the '80s Oracle Corp. had a restriction from including Oracle
product in any product comparison, such as benchmarking. 

Sometime in the early '90s Oracle Corp. lifted that restriction. It may
have something to do with the fact that Oracle was finally running fast
enough to look good next to Informix, et. al. 

Microsoft picked up on this mode and had similar restrictions inserted into
SQL Server licenses. I didn't know about that part of Microsoft's license
until I heard Larry Ellison talking on a radio interview, blasting Uncle
Bill for this dispicable practise!

Okay, we use proxy :( . Also, the URLs are rewritten by Apache so that all the
relative links don't go to http://zope-host.nipltd.com/mydomain/*whatever* as
opposed to http://www.mydomain.com/*whatever*

What I was thinking is to write a Site Access rule as follows:

If the host name is zope-host.nipltd.com:
	do nothing
else
	<dtml-call "REQUEST.setURL(path='/')">

Maybe storing zope-host.nipltd.com in a property of the root level folder too.
My only problem is finding out what the host name is.

Will REQUEST.environ.HTTP_HOST be set by the time an Access Rule is called?

Richard,

The equality check on AUTHENTICATED_USER will always fail because your
comparing an object with a string.

You need soemthiong more like :

<dtml-if expr="AUTHENTICATED_USER.getUserName()=='zope'">

Subject: [Zope] how to tell if displayed in a frame
References: <38C82A33.B333748A@open.ac.uk>
Message-ID: <38C9047B.53DAD777@vt.edu>

It can be done in server-side code, if you know when you put the
document in a frame or not.
Something like the following might help:

In the document in question, do some code like:

<dtml-if in_frame>
...display definitely in frame
<dtml-elif not_in_frame>
...display definitely not in frame
<dtml-else>
...default display, which may be the same as one of the above
</dtml-if>
You will probably want to factor out the duplicated content into
subsidiary methods.

Now, if you want the default view, call it as <dtml-var mydoc>

If you want it in its frame view, call it as <dtml-var "mydoc(_.None, _,
in_frame=1)">
You might want to make a dtml method called e.g. myframedoc with the
above code so you can call it as a url.
<frame src="myframedoc" title="blah">

Another way is to call the document in HTTP:get format in the frameset.  
like: <frame src="mydoc?in_frame=1">

Thanks for solving the immediate problem Phil - another UK Zopista - 
there's a few of you out there ! I think I've had help from all of you in 
turn :-)

However I think this reveals a basic problem with the syntax which is 
causing me grief and presumably there are others like me out there.

I would expect an object to behave consistently wherever it was used - so 
if it renders/returns/evaluates to 'zope' inside a dtml-var I would expect 
it equally to render/return/evaluate to 'zope' inside a dtml-if.

If it doesn't then surely we have an inconsistent syntax. How do we know 
how any object is going to behave inside a dtml tag ?

Any comments ?

Why do you want to do this? Have you thought of why it is there?

Create a folder 'Foo' with an index_html method in that Folder, and a 'bar'
method. The index_html document contains a relative link to bar
(href="bar"). Next, go to the URL:

  http://your.server.name/Foo

Note the lack of a trailing space. If you now follow the relative 'bar'
link, you'll neatly end up in http://your.server.name/Foo/bar.

However, had you removed the BASE tag, your browser would have attempted to
load http://your.server.name/bar instead. This is because the relative URL
is offset against the last slash in the URL. The BASE tag however, tells
your browser that the actual URL of the document it is showing, contains an
additional slash.

So, unless you have a really good reason, you don't want to remove that
slash. And if you do, you have to make absolutely sure that the visitor will
never end up on a URL of which the browser needs to be notified is different
from the actual URL.

Richard,

As someone earlier today on the list said, "if it's in quotes it's python"
(or something similar).

Basically Python rules apply when using any expressions in zope dtml-var and
other tags.

Well, that's how I think of it.

Message-ID: <013601bf8aa5$e2733060$0a00000a@smartway>

Hi all !

I try to learn Zope...

I have a very simple ZClass myClass.
This Class has few properties (let's say title:string, description:text).

I would like this class to have 2 methods that can render its instances
simply.

Let's say DTML Methods :
render1
render2

I've made thoose two methods in my Class :
ex :
render1 :
Title : <dtml-var title><BR>
Description : <dtml-var description fmt="structured-text" newline_to_br>

and render2 :

<B>Title</B> : <dtml-var title><BR>
<B>Description</B> : <dtml-var description fmt="structured-text"
newline_to_br>

(the examples are stupid !)

But when I call the methods from the index_html of my content folder like :

<dtml-var "myClass1.render1">
or
<dtml-var "myClass1.render1()">
or
<dtml-call "myClass1.render1(myClass1)">
or
<dtml-call "myClass1.render1(_.None)">

None of theese shows me the infos :(((((
Sometimes, i have AttributeError, sometimes Authorisation PB :(


Please help !

I still think it's an inconsistent syntax.  It should be possible (by
overriding __coerce__, I think?  I haven't had time to look this up yet)
to make the == operator do something different.  AUTHENTICATED_USER is
often used as a string (at least what I've seen of it ...)

Also, "if it's in quotes it's in python", why do I need to do _.str()?  
why does dir() not work?  It seems like some pretty horribly munged sort
of python...

Message-ID: <NDBBLENPLCPAHKODFHNGAEMHCNAA.morton@dennisinter.com>

A number of people have expressed a desire to have XSL support in Zope. The
projects I am working on also seem to be needing the application of XSL, and
whilst we can (and will) use some external XSL processor, it would seem that
a 'cleaner' solution would be to have XSL support directly in Zope.

I originally came to want to use Zope because I needed a tool that allowed
the manipulation of a persistant tree of objects; my prototype was done in
XML, but it needed persistance, an interface, and a programming language,
hence the use of Zope. Even having only XPath support would be an extremely
usefull way for packaging up simple 'queries' on the Zope database.

Ive been looking around at the Python XSL implementations and the
FourThought 4suite is looking pretty damned good, especially considering
their goal of eventual ODMG 2.0 support. Zope desparately needs some
standards compliance, even if only for the buzzwords.

The question on my mind is: how much do other people want XSL in Zope?

Im willing and able to put some $$$ up for a bounty on this. Is anyone else?

I guess Id also like to heard what DC has to say about this; whether they
are willing to have an external group contribute/merge a key technology into
their codebase, and if they have any preferences about who this group might
be.



---------------------------------------------------------------

Heres what Uche Ogbuji of FourThought has to say about Zope
http://www.pythonjournal.com/volume1/issue2/col-intranetpython/

The Zope Dope
Digital Creations, fresh from a capital infusion, has given Pythoneers their
first complete native Web application platform in Zope.  the "Z Object
Publishing Environment".  Zope is similar in scope to Cold Fusion or
SilverStream, but open-source and python-powered.

Zope accumulates many bits and pieces of a successful Intranet site.  It
incorporates a database management system with object extensions (which,
unfortunately, doesn't yet support the Object Database Management Group's
specifications) as well as facilities for developing template Web sites, an
application framework, a CGI mechanism for handling HTTP requests for
objects, an HTTP and FTP server, and a comprehensive application framework
to tie it all together.  Z Templates are developed using a proprietary
XML-based language, the Document Template Markup Language (DTML).  ZTML does
make some departures from the XML community in such areas as style-sheets,
but it is hoped that Digital Creations or other contributors to Zope will
work to close that gap.

Zope is a synthesis of Digital Creations' many earlier products, such as
Bobo, Principia and PCGI.  Bobo has been especially popular among Python/Web
programmers, and Zope looks poised to retain the tradition.  If Zope can
move a bit closer towards object database and XML-processing standards, it
is likely to be quite popular outside the Python community as well.

Subject: [Zope] External Method to view ZSQL Record
Message-ID: <00c901bf8ab6$b38ce6e0$5e577e86@jmu.edu>

To all Zopists,

I would like to use an External Method to access a record field from a ZSQL
method by referencing another field in the record.  If I set the External
Method up such as:

def viewfield(self,reference_field,search_value,field_value):

where:
reference_field = So that I can tell it the field I want to reference
search_value = The value of the reference_field to query
field_value = The value of the returned field, that I was looking for

Do I use a "return" or a "result" or something else?  I still don't have a
handle on python yet, so I'm not sure what to put on the second line of the
method.

Thanks for all the help so far, and thanks for the help on this, in advance.

Message-ID: <NDBBLBELNHAPHBBCOIFDGELDCBAA.ewalstad@energywright.com>

Hello all,

I have tried everything that I can think of (& a lot of what some of you
could think of) to get MySQLdb to compile and install.  I have had no luck.

So, I am now trying to install MySQLDA (a step back) and am still having no
luck.  I'm hoping that the MySQLDA problem is related to the MySQLdb problem
and that one of you will be able to point me in the right direction.

Here's what happens when I try to install MySQLDA:

First, the 'make -f Makefile.pre.in boot' script seems to work fine, but
I'll include the output anyway, just in case.

As far as I know, I don't thing it's possible in Zope. I'm very interesed in a
way to do that, so I thought about a possible solution:
- make an empty class in python, e.g. MySuperClass;
- when creating your ZClass, make MySuperClass one of its Base Class;
- if you want to modify your ZClass Base classes, just add super classes to
MySuperClass and create/modify and __init__ method in it:

class MySuperClass(NewBaseClass01, NewBaseClasse02...):
	def __init__(self, parmeters...):
		NewClass01.__init__(parameters01)
		NewClass02.__init__(parameters01)
		...
It sounded a good idea to me and worked fine in python. However I got:
******************
Error Type: TypeError
Error Value: unbound method must be called with class instance 1st
argument
******************

Not very useful but who knows. Let me know if you figured out a solution.

Hello,

I am trying to display a sequence of numbers with next to each of them the

buffer to add at each cycle the value of the new number. But I can't figure 
out how to create a variable.

Can somebody tell me how to declare such variable?

I've always noticed the same thing, over a period of months. I'd also like
to know what it signifies. Is the list stored in the ZODB, and is this
therefore indicative of the kind of performance than can be expected with 6k
records? Or a relational table? It's not very impressive, makes the member
list something to avoid, and it's undoubtedly fixable...

Even if it gets "fixed" right away, it'd still be useful to know what the
problem was.

Subject: [Zope] Trees with DTML Methods?
Message-ID: <38C9562C.8B33C8E3@pacsg.css.mot.com>

http://www.zope.org/Members/anthony/tree-coding-tricks
"How-To: Some Neat Tricks with dtml-tree"
seems to imply that I can use trees on things other than ZODB objects.

But I've been banging my head against the wall on this for some time,
and I can't figure it out.

Here's what I've got:

An index_html document:
<dtml-var standard_html_header>
<dtml-call "REQUEST.set('eid', '1000')">
<dtml-tree id=eid branches_expr="GetEmployees(eid=eid)">
  <dtml-var eid>
</dtml-tree>
<dtml-var standard_html_footer>


A DTML Method called GetEmployees that returns test data:
<dtml-if "eid == '1000'">
  <dtml-return "[1001, 1010]">
</dtml-if>
<dtml-if "eid == '1001'">
  <dtml-return "[1002, 1003]">
</dtml-if>
<dtml-if "eid == '1010'">
  <dtml-return "[1011, 1012]">
</dtml-if>
<dtml-return "[]">


What I get is an infinitely expanding tree of two pairs of 1000's:

- 1000
    + 1000
    - 1000
        + 1000
        - 1000
            + 1000
            + 1000
+ 1000

What I don't understand is how the stuff from branches_expr is supposed
to change things around.  And, not coincidentally, that seems to be the
problem with this code....

Thanks for any help.

Uuupps, Thanks. I knew I'd forget to remove it.
I already got used to reading time in epoch UTC ;-)
worldpilot.1.0.4 fixes it.
I included WPsmtplib.py and WPimaplib.py and use them now instead of the
originals to avoid dependency problems in these modules

I took a look at the imap code. it basically complains that
the SELECTed folder is not read writable.
As far as I can remember the problem may be that UW IMAP locks your
folders when they get selected.
Possibly you're accessing that folder with a different client
concurrently?

Let me know if that's the problem, since I have heard about this problem
a few times, and I thought it was a locking issue on UW IMAP.

If not we'll have to look into it.

Ryan

You are using a version of MySQL that is too new, I think.  I haven't seen this
one in a while, but I think I recognize the error messahes.  Try dropping back
to 3.22.25 (3.22.26 might work, but I know that .25 works and >.27 does not).
Send me a private email if you need a copy of the rpms.  I am sure I have thenm
somewhere

It is not inconsistent because all things behave consistently within
quotes and consistently without quotes.  You just have to know the rules
of each case.  Granted, it's not pretty, but it's consistent.

It's never used as a string because it is not a string.  You can't use
the word 'string' unless you are talking about python expressions.  DTML
does not have types, you must rely on python's expression machinery to
get down to thinking about the types of objects.

This is for security reasons.  We've overridden many of the built-in
functions like str and dir with our own so that DTML programmers cannot
do mean and nasty things, intentionally or unintentionally, from DTML.

It doesn't use the Catalog.  It's a plain Zope folder.  This means that
the folder object, including it's dictionary of childer, is loaded into
memory every time it is accessed.  This is the inefficient part. 
Folders were never meant to contain this many objects.  This is not
neccesarrily a lack, Linux directories are not that efficient either. 
Try putting 6000 files in one ext2 directory and then type 'ls'.  Pack a
lunch.

What is needed is a Folder object based on a more efficient storage
mechanism, like BTree.

I'm all for this.

And here comes the but.

But, 4Suite is not suitable (i.e. doesn't compile) for Win32 at the moment
(that's from the horses mouth, well Uche at least).

There was talk of win32 binaries but they seem to never have materialised.

I sopke to Uche today, and supposedly there are people who have had it
compile under win32. Im tracking them down at the moment. 4Suite may not be
suitable at the moment, but not because there arent win32 binaries.

I suppose line 1125 of mySQLmodule.c is something like:

Yes!  But I think that the concurrency might be happening from
Zope/WorldPilot?  I.e. that it is submitting another command prior to
the first results?  I ran (the patched) imaplib.py by itself (it has a
"sample session") which gave "reasonable" results...

Or, it might be an instance of the way recent UW imap daemons deal
with the maildir issue, copying files to the local user account from
the mail spool...  (see documentation, which I'm not yet sure that I
understand; but then again, I'm a research biostatistician, not a
sysadmin/www-master...).

I replicated it using UW imap locally on the linux (debian) box.

Maybe I'll try firing up Cyrus -- does anyone know if it "drops in" in
the same way that UW Imap does?  (i.e. install and go...).  Debian's
got it, so maybe I can do that...

Now I'm confused. You have to restart the Zope server after untarring the
package. Does WorldPilot show up on the Product Management page? If not maybe
it was unpacked into the wrong place. Did you set up the directories that are
listed in the INSTALL.txt. One change that can be made to the instructions is
the permission settings on the created directories. You can set them to 755 and
user to the user that runs Zope and group to its primary group. For example I
run zope with user jack.users so my directories look like this:

drwxr-xr-x   2 jack     users        1024 Feb 17 21:33 sessions
drwxr-xr-x   3 jack     users        1024 Feb  1 23:04 storage
drwxr-xr-x   2 jack     users        1024 Feb  1 23:04 user

The first time installed WorldPilot I think I had a permission error and ended
up with a broken product in the Product Management section.

Hope this helps.
Jack

Hi Patrick -

What happens if one manually deletes a file that is part of a transaction
involving many objects/files? How would transaction boundaries be enforced
on a filesystem? I am interested in hearing your thoughts on the issue
since it seems you have already done some work on it.

The following test was done with the WorldPilot Note facility and I suspect
would be similar in the calendar. I have three test users on the system
tester1, tester2, and tester3. I logged in as tester 1 and created 3 notes: 1
private, 1 public, and 1 confidential. I then added tester2 in the sharing page
with browse and read access. Tester3 only got browse access. Tester1 sees all
three notes, tester 2 the public and confidential, and tester3 the public. If
you have resources that need scheduling you should be able to set up userids
for the resource and let it have a calendar that is open to appropriate people
to read and/or edit. There may be a easier way to do this and maybe Ryan will
let us know if/when he sees this. :-)

I've not had a chance to work much with Exchange Server but if memory serves it
doesn't do much more than a standard IMAP server in the sense of
mailboxes and shared folders. It provides support for calendaring and address
books (with client support for LDAP, another of the things on my list of things
to learn.) So beyond that it depends on what they want to do. 

Good Luck!

Yep, although this would greatly improve my assertion that unix dirs,
like zope folders, are not efficient enough to handle 6000 objects, it
would not effect my assertion that zope folders need a more efficient
storage mechanism.

I know this is probably what you meant Patrick, I just wanted to be
explicit.

In this light, I have experimented with a BTree folder.  I posted the
code to zope-dev eariler this week.  Anyone get a change to see it? 
Anyone interested in actually improving it?

I have done nothing on this, unless you count daydreaming. ;>) At one
point, I had idly asked if anyone thought this might work, expecting
that some knowledgeable soul would immediately shoot the idea down.
Surprisingly, both Jim Fulton and Hans Reiser seemed to see that it was
in the realm of possibility, but not easy.

Of course, you have identified the hard part. Back in December, Jim
Fulton had the following reaction (below). Afterward, someone else at DC
told me that when Jim says it "getting transactional semantics right
might be a tad tricky" he means your head will explode. :)

Still ... since Linus Thorvalds has refused to add the complexity of
journalling to the Linux buffer cache, the people hacking on reiserfs
and other journalling filesystems, have been forced to implement their
own mechanisms for keeping track of dirty data. So one wonders if these
might be adaptable in some fashion, much as they are used to support
high availability network filesystems like Intermezzo, which exploits an
existing filesystem as a cache and wraps around it.

So, in answer to your question, I have no idea. ;)

===========

[Jim Fulton]
Would you imagine using the reiserfs as a ZODB storage?
If one was going to use a file system as an object store, 
then the reiserfs would be attractive due to it's effective
support for small files. Is this what you had in mind?

The ZODB has a well-defined "storage interface" that should
make implementation of a reiserfs- (or just an fs-) 
based storage reasonably straightforward, although getting
transactional sematics right might be a tad tricky.

Jim

One possible approach here is to have your proxy add a magic path element to
the path, sending http://www.mydomain.com/PATH to
http://zope-host.nipltd.com/PROXIED/mydomain/PATH.

Then have an Access Rule which says:

If "REQUEST.path and REQUEST.path[-1]=='PROXIED'" then "REQUEST.path.pop()"
and "REQUEST.setURL(path='/')".  There doesn't have to be a real object
called PROXIED, it's just a flag to be recognized and discarded by the
Access Rule.

Subject: [Zope] Zope under low Disk Conditions
Message-ID: <200003110340.NAA88677@mail.theinternet.com.au>

I've just had a few frustrating hours trying to work out what was going on
with Zope.

It stopped allowing the addition of DTML-Methods. The connection would just
hang waiting for the Method to be created (also happened with DTML-Documents).

Turns out that /tmp was out of space temporarily. -- the disk that Zope
was running on had plenty of space.

It'd be nice if it would return low disk space errors rather than go off
into never-never land.

When in doubt, read the fine manual.  The _actual_ syntax you are using is::

  <dtml-var name="AUTHENTICATED_USER">

which can be abbreviated (and is, by almost every Zopista) as:

  <dtml-var AUTHENTICATED_USER>

The "name" form of the var tag is the "preferred" one, for the types of
applications DTML is really designed for: simple scripting of objects built
in Python.  It does several "automagic" things with the name:

  - If it is callable, calls it, passing the current object, the
    current namespace, and the REQUEST;  it then replaces the object
    with the result of the call.

  - If it has a string coercion (__str__) method, calls that and
    replaces the object with the result.

This behavior is the Right Thing (TM) for simple scripting;  but it _isn't_
Pythonic (the automagic stuff smells more Perlish, really).

The "in quotes" version is really::

  <dtml-var expr="AUTHENTICATED_USER">

but can also be spelt (and mostly is)::

  <dtml-var "AUTHENTICATED_USER">

The "expr" form of the var tag evaluates the Python expression (in this case,
to the object AUTHENTICATED_USER).  For fairly obvious security reasons, the
evaluation takes place inside a restricted namespace, without the usual
builtins;  the "safe" builtins are made available as members of the
"_" namespace.

The simplest disambiguation possible is to cease using the shortcut forms, and
always spell what you really want:

  <dtml-var name="AUTHENTICATED_USER">  <!-- DWIM: give me text!!! -->

or

  <dtml-var expr="AUTHENTICATED_USER.getUserName()"> <!-- DWIS,NWYTIM -->

Hope this helps!

I now just take my log files and run it thru a script to correct the

I got a quoted version of the object if I made

It does not evaluate the tags and quoted all < with &lt; and so they all

What rules determine when it will be quoted?

Also, I got the same result if I have

I can work around with

<dtml-with folder>
<dtml-var obj>

But how can I workaround "this"?

Actually, the Members roster is a bit more efficient. It uses caching to
store the results. This was added only recently, before the roster was
offline for a while because it was taking too much resources.

What happens is this:

If the cache has expired, or is empty, we do go through all 6000 Member
folders, and check wether or not they are listed. From listed Folders (just
over a 1000 now), we store the id and title in a list. This list is sorted
on id. Next we store the total number of Members found.

Then, we loop over the 6000 Member objects, and check wether or not they
have been active in the past two weeks. The number of active accounts is
also stored.

Together with a timestamp, this info is then stored as a volatile dictionary
attribute, and returned.

A next call to Members will return this cached information. Timeout of the
cache currently is 60 minutes. So, the batched pages and the searches use
this cached information.

There are a few reasons why it still may be slow:

1/ The cache has expired or is empty: we have to fill it again.

2/ The cache is per-thread. It isn't persistent, and therefor not shared
between threads. Your request could hit on thread first, your next request a
different thread, and then have to wait for the cache to fill twice.

3/ The volatile attributes don't hang around as long as I expect them to.
Maybe the object cache is a bit too aggressive, I haven't figured this out
yet. I haven't been able to get the cache to stay around for more than 20
minutes, but it is hard to verify and debug with 7 threads. I am not sure
about this one, because in the course of some extra testing I got to see
cache older than 20 minutes again.

4/ The dictionary containing the cache may be coming from swapped memory.
Currently, the Zope.org process grows quite large. This may have to do with
the up to 42000 Folder objects loaded into memory at any time. The Members
Folder holds references to 6000 Member Folders, and there can be up to 7 of
them (7 threads). This is an area where a BTree based folder would _really_
help.

5/ Plain network lag. Check other pages on Zope.org.

6/ CPU is hogged. The rendering of the ZQR is very expensive. If it runs,
the whole of Zope.org suffers. I am seriously considering disabeling it.
People really onlly need the pre-rendered version. I was testing just now,
had to wait way too long, and noticed someone was looking at both the normal
ZQR (rendering from XML), and the print preview version. The Members roster
came from cache.

I CCed David Kankiewicz on this, so he knows =)

1000 is still too many to be efficient in a regular folder.  You're
right that a BTree is probably the way to go here.  I didn't know about
the caching efforts, it seems like you went through some hoops to come
up with a better solution.

I think that we should seriously look into or have someone in the
community look into my BTree folder efforts to come up with a better
solution.  Depending on when I wake up tommorow, I'll see if I can fix
the various bugs in BTreeObjectManager and make an alpha release.

The only big question I can think of is, should BTreeObjectManager
replace ObjectManager?  Obviously not at first, but we should maybe look
into replacing OM with a more efficient form.  Looking strictly at
performance, I don't see any reason why this should be the case.  In all
cases, a BOM should be faster than an OM.  BOM are not any less
efficient in resource consumption either, and they are written in C, not
python.  Zope's BTree implementation is also very well tested, and
written by Jim, 'nuff said. ;)

Works for me. Especially if it results in a more up-to-date version in
pre-rendered style. Pre-rendered is about 6 months old, IIRC.

I imagine Zope is like anything else (basically) you would run in a
chrooted environment. Give it the things it needs, and it should be
fine.

You may want to have alook at the Zope Product code for Zope Studio. I added
methods to the Application class, exactly what you want (watch it, long URL,
you may have to reconstruct):


http://cvs.zope.org/cgi-bin/cvsweb.cgi/ZopeMozilla/ZopeStudio/ZopeProduct/Zo
peStudio/ZopeStudioRDF.py?rev=1.2&content-type=text/x-cvsweb-markup

The important bits are 'import OFS.Application', and to assignments to class
members in OFS.Application.Application:

  OFS.Application.Application.zsTreeRoot = zsTreeRoot
  OFS.Application.Application.zsContainerRDF = zsContainerRDF

Note that the 1000 items is a sorted list of (id, title) tuples, _not_
Folder object references.

Once the cache is filled, we only have to display the precooked numbers,
take one _.len() of the listed members list for display, and have dtml-in do
it's magic on the afore-mentioned list.

The problem lies mostly in the fact that we have to access each and every
Member Folder to check if it is listed. Even if we use a BTree, we'd have to
load every Folder into memory. The same for the User objects in acl_user.

This is a side effect of using Extension Classes. From ExtensionClass.stx:

  Overriding methods inherited from Python base classes

    A problem occurs when trying to overide methods inherited from
    Python base classes.  Consider the following example::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            Spam.__init__(self,name)
            self.favorite_color=favorite_color

    This implementation will fail when an 'ECSpam' object is
    instantiated.  The problem is that 'ECSpam.__init__' calls
    'Spam.__init__', and 'Spam.__init__' can only be called with a
    Python instance (an object of type '"instance"') as the first
    argument.  The first argument passed to 'Spam.__init__' will be an
    'ECSpam' instance (an object of type 'ECSPam').

    To overcome this problem, extension classes provide a class method
    'inheritedAttribute' that can be used to obtain an inherited
    attribute that is suitable for calling with an extension class
    instance.  Using the 'inheritedAttribute' method, the above
    example can be rewritten as::

      from ExtensionClass import Base

      class Spam:

        def __init__(self, name):
            self.name=name

      class ECSpam(Base, Spam):

        def __init__(self, name, favorite_color):
            ECSpam.inheritedAttribute('__init__')(self,name)
            self.favorite_color=favorite_color

    This isn't as pretty but does provide the desired result.

--
Another way, and I used this, is by bypassing the method binding, by
accessing the unbound method. The above example could also be:

        def __init__(self, name, favorite_color):
            ECSpam.__init__.im_func(self, name)
            self.favorite_color=favorite_color

The propertysheet variables become class variables, which are persisted as
well. So when you retrieve an instance, the persisted class that described
the behaviour of that instance is taken from the ZODB, and the new persisted
class has the .d attribute there.

In your python class however, .d is a instance variable, it gets set when a
new instance is created and __init__ is called. And exisiting instances
don't get __init__ called again, after all they were initialized already.
They only get their current state restored, and that state never included
the d attribute. Only on new instances, where __init__ is called, does d get
set.

You could get around this by making d a class variable, by adding d='I am d'
to you class definition. Alternatively, you could use the __setstate__
method, it is called when the instance is retrieved from the ZODB. It
revives the state of the object, and you'll have to remember to call
Persitant.__setstate__ as well:

    def __setstate__(self, state):
        Persistent.__setstate__(self, state)
        if not hasattr(self, 'd'):
            self.d = 'I am d'

'this' is an object reference, and it is being stringified. So the source is
returned, HTML quoted.

What do you want to achieve? Calling itself? ot very wise, as it would cause
an infinite loop..

If you want the source, do <dtml-var PricipiaSearchSource> and give the
Document a Proxy Role of Manager.

Well, here's a STUPID_LOG_FILE and a DEBUG.LOG during a crash.  I've
annotated the DEBUG LOG` as to when I think the crash occurred.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

I guess thats not the point here. Sure you can use POST for forms as
well
as GET. You can even "construct" A form-like URL for GET using
?var=value&var2=value
but you cannot send something inside forms without javascript over a
href-tag.

There is a really good Howto on the zope.org website that explains in detail how to
call a ZSqlMethod from an external method, and how to parse out the results
afterwards.  Follow those instructions and you shouldn't have any problems.  Your
email spells Extensions as 'Extentions', so make sure that this is not your problem
(probably just a typo, I know, but I thought I would check).

This might be a better idea. I'd use an external file, however.

User will alway read from file, is fast (shared locking). A cache update

This doesn't solve this. It's not the surfing of all those folders, it's the
accessing of the Members Folder itself. It's that folder that holds the
references of 6000+ sub Folders.

It is necessary when you want to call a DTML Method or Document from a
Python expression and you want that DTML Method or Document to be able
to look things up as an attribute of a 'client' or in your current
namespace (or any namespace you provide).  You can omit it when you are
using a DTML Method or Document _by name_ in DTML.  Note that:

<dtml-var IManager>

is the same as:

<dtml-var name="IManager">

and:

<dtml-var "IManager()">

is the same as:

<dtml-var expr="IManager()">

So most people use the first and third shorthand forms to use an object
by name and to execute a python expression respectivly.  When the DTML
Engine sees that you are using an object by name, it tries to do clever
things, like detect if it is a DTML object and to call the method and
pass the namespace 'magically'.

When the DTML engine sees that you are using an expression, it assumes
you know what you are doing and does no magic for you.  Therefore, you
must explicitly pass in the namespace.

> I'm also very unclear
> as to just what the 'client' is, especially since most of the examples
> I've seen involve passing in None for the client.

The 'client' is an object that you want to use as a namespace.  For
example, if DTML Method 'IManager' wants to find the name 'img' you can
pass a client object, and the method will try and do a getattr(client,
name) (in this case, name being 'img').  If you pass a namespace, then
it will try and do a namespace[name].  If neither of these succeed, it
will look for the name in the optional list of keyword arguments you can
provide.  If that fails, it raises a NameError.

The reason why it is None in most cases is because you want your method
to look things up using the Zope DTML Namespace (affectionately known as
'_').  In some special case however, you may want to explicitly provide
some other object.

This is single handedly the #1 obfusication in Zope and the most
frequently asked question.  We, of course, did not obfusicate this on
purpose.  When DTML was first concieved it worked by name only, so the
behind the scenes magic was acceptable and intuitive.  Later, we added
python expressions, and the ugliness of calling DTML Methods and
Documents became aparent.

Message-ID: <Pine.BSI.3.96.1000311155818.539I-100000@twirl.bitdance.com>

I've got a simple CatalogAware ZClass.  (CatalogAware is the only
class I added to its inheritance list.)  Everything seems fine,
but if I access an instance of the ZClass through the Catalog by doing, say,
getobject(data_record_id_), and then inspect the 'id' property of
the returned object, instead of getting the id of the object I get
the id of the folder in which the Catalog lives.  When I create
class instances, the 'id' in the meta-data is correct.  If tell
the catalog to update itself (or tell an item listed in the catalog
to update itself through the catalog management screen), then
suddenly the metadata id is also the id of the folder enclosing
the Catalog.

Is this a bug, or am I doing something stupid?  The object appears
under its id in all of the management screens, including the 'indexed
items' tab of the Catalog.

Hi DTML Gurus,

I am a newbie with DTML and i am trying to do the following with this script

1) using the subdirectory RegisteredUsers, check if a ZClass object of type
Player exists in the RegisteredUsers directory with an id that matches that
in the Request ( a form from the client ). This currently doesnt work for
some reason and i get the else case even if the object does exist.
2) In the else case i am then trying to create a new object of type Player
 a ZClass object defined in the GameSite product ).  I am creating the
object correctly in the correct place but the next bit of setting the
properties of  the player object does not work, and the object properties
are blank.

HELP !!

I have checked all the documentation for zclasses, dtml faq etc.  Can any
one help?

Is  there an easier/better way of achieving what i am trying to do, or am i
barking up the wrong tree ?


<dtml-with RegisteredUsers>

<dtml-if REQUEST['new_user_name']>

User currently exists

<dtml-else>

New user

  <dtml-with "manage_addProduct['GameSite']">

I think I heard somewhere that it's now equal in speed to CPython, but 
I'm not sure. People use it to script Java components and such. It seems
to be reasonably popular for things like that in Java-land.

[snip explanation why open-source like collaboration is harder for languages]

It's hard for language *design*, yes, but it's less hard when you're doing
language implementation (for instance a faster one), and it's easier still
when you're writing libraries and such. And it does happen for language
design as well -- the Python static type design is currently being fleshed
out (in bursts) by the types-SIG (though of course Guido does final
approval about what goes into Python proper).

Hm, I'm not entirely sure how to find it other than digging through the
types-SIG mailing list. Try something mid-january.

You'll find some of my silly messages too. :) The types SIG came quite
a long way after Guido proposed closing it down for inactivity. It's a bit
more quiet now, I believe.

There are various tools out there for Python which do offer this kind of
functionality, though, I think? Check at the vaults of parnassus sometime:

Why not use a relational database? Is it too immature that way?

I think I see what you are trying to do here, but I don't think
DTML works that way.  The array reference is a python expression,
so you have to go to an expr.  But if you just enclose the above
in quotes you'll be testing whether or not REQUEST has a non-null
new_user_name variable.

One way to do what you want would be (tested):

<dtml-with RegisteredUsers>
  <dtml-if "new_user_name in objectIds(['Player'])">
  User currently exists
[...]

REQUEST is on the name space stack, so new_user_name will be found
without having to refer to REQUEST explicitly.  'objectIds' returns
a list of object ids, and the argument gives a list of meta_types
of the Ids to return.  So this call results in a list of just the
Player ids.  The python 'in' operator checks to see that the
left hand string is a member of the list of strings on the
right hand side.

Note: you'll run into some interesting issues with your planned
setup of the number of players gets large (say that large is several
hundred) due to practical limits on the capacity of Zope Folders.

Well, you may want to take a look at GUF and perhaps the (RealSoonNow) the
Portal Toolkit, but they may both be overkill for your application.
It depends on just what functionality you are trying to put into
your Player objects.

I forget which How-To I got this out of (maybe the CatalogAware
How-To?), but I think the call to update the property list function
name is (copied from some of my own code):

propertysheets.<your-sheet-name>.manage_changeProperties

Since your cut and paste dropped some stuff there, though, that may
be what you have, in which case I don't know why your properties
aren't getting updated.  Though you might try adding the _.None,_
arguments to the beginning of the call.

I'll repeat my question; why not use a relational database? Do you
need an object database? How is the ZODB too immature?

I'm having some trouble with it too, but perhaps that's just not being
familiar with the concept yet. But at least it looks less horrid than
some map()s and such.

Why so? I myself think Zope's source is an argument for explicit interfaces. :)

Well, tuples can be used as dictionary keys, lists cannot.

Forcing a *copy*, implicitly? But Python works with reference semantics
only? It's be nice to have a way to declare stuff immutable, I think,
but I'm not sure how often one would need to use it. There's something
to say for knowing something's a tuple, instead of having a list and
having to know whether it's immutable or not. Though perhaps that's
not a big problem in practice.

But that might result in a lot of incomprehensible code. I'm not sure if 
I'm in favor of having 'out' parameters anyway. constness as defined in
C++ is also tricky, as it infects code; everything that touches it
needs to be const-correct. Python tends to be less strict in this area.

[optimized statically typed modules calling classic python modules, why
is this tricky?]

Yes, it is doable but tricky in combination with static typing. See
the types-SIG for more info; I believe Guido has some messages on that.

Strange problem here - likely not related to Zope directly.  When our
content guys edit the DTML through the Zope management interface in IE 5.x,
the pages are properly displayed in IE 5.x (and assume 4.x).  However, in
Netscape, some pages do not display properly.  After running the DTML though
a code validator, the results indicate that the H/DTML is correctly
formatted for IE/Netscape 3.x and above.  We're aware of the normal
differences in table formatting, for example, between the different
browsers.

However, viewing the pages in Netscape 4.x, the source has all the "<" and
">" replaced with question marks.  This has been tested in Windows 98/NT 4.x
and Linux RH 6.1.

Now, I'm open to suggestions.  I am tempted to think this is a result of
some encoding issue, or perhaps  IE 5.x's handling of extended characters
but I'm at a loss.

This is likely some silly setting that we've overlooked but I thought I'd
check here first.


Thanks in advance,

I've seen that behavior under Linux Netscape when viewing some sites.

Having worked with C++ for a long time, and later with Java,
I can tell you just how much I hated the whole thing about
data "encapsulation."

The whole mumbo-jumbo stuff about data hiding has one and one
single purpose: divide the programmers into engine programmers
and app programmers, so the engine programmers and exercise
full control over app programmers. It has more to do with
MONEY and corporate POWER CONTROL than with technology.
The private/protected keywords are an enterprise feature...
designed for big companies.

And generations of students are taught into this stupid
c**p about "data encapsulation." Funny thing is, many actually
buy the idea, get burnt for a few years and refuse to
acknowledge they are being burnt ("if it is mentioned in
textbooks, there must be a reason... it must be good for me..."),
and only then to realize much later... hmmm.... maybe
"data encapsulation" should be done by convention and not by
syntax.

Yes, another thing that I consider to be stupid in C++ is the
overuse of const, or its use at all. Again, generations of
programmers are taught into this thing about usage of const,
and buying into it without questionning.

Python uses references for object parameters in function calls.
It can also return tuples. That's enough. Really.

Keep Python simple. The role of Python is CP4E (Computer
Programming For Everyone.) In Java or C++, you have to type
all the extra stuff about public/ private/ protected/ void/
abstract/ static/ synchronize/ final/ const/... before you can
do something. I know many people that live in that world and
refuse to simplify their lives... well, then again, I also
know people that lives in the Perl world and insist that Perl
is a very readable language. :)

So to keep all start tags and end tags in the same object.

I can do that for a folder by making the method call index_html and call the

But I want to publish anyobject by adding this method to it:

abc/publish

will warp abc with the apropriate html codes which traditionally in zope is
done by header, var, footer. which might result in the opening tags in
header and end tags left in footer.

Subject: [Zope] Redirection problems
Message-ID: <20000311202916.B8706@magellan.midsouth.rr.com>

Right now, visitors to my site at http://www.centralchurchyouth.org go
through the following redirection:
http://www.centralchurchyouth.org (running IIS)
	to
http://www.centralchurchyouth.org:8100/ (running Zope)
	to
http://www.centralchurchyouth.org:8100/Home/ (the real home page)

This works in Netscape but doesn't work in IE. The user gets all the way
to the third page but it doesn't render. Upon further analysis, all of
the absolute_url calls (like "<dtml-var "stylesheet.absolute_url()">"
produce http://www.centralchurchyouth.org/xxx instead of
http;//www.centralchurchyouth.org:8100/xxx, so the page has a broken
logo, etc.

I think it has to go with the HTTP session between IE and
http://www.centralchurchyouth.org:8100/, but I'm not sure what. Using
wget also returns a correct page.
Surely someone has come across this issue.

[snip]

Having worked with C++, Python, and Object Pascal for a long time, I
tend to agree, with a few modifications:

- encapsulation helps keeping the code self-documenting -- nobody can
accidentally access hidden members;

- it aids documentation tools in that visibility rules can be seen as
metadata -- "source navigator"-type object browsers can categorize
members (methods and data) into their various protectedness; and

- most significantly, hiding data and replacing direct access with
clearly defined accessor methods lets you control access (such as
synchronizing access from multiple threads) and also provide behaviour
-- often data is calculated on demand rather than stored, and often
related objects must be notified when data is changed.

Python doesn't have accessor methods, but uses __setattr__ and
__getattr__() instead, which is less intuitive -- a code browser cannot
easily infer the access interface from the class definition alone -- and
certainly slower -- but also more flexible. 

I'm a big believer in pure-code interfaces, keeping data hidden and
restricting all reads and writes to accessor methods; languages such as
Dylan and Object Pascal fortunately have accessor-method support built
into the language, so referencing an attribute foo.name would actually
be resolved by the compiler into a call to foo.GetName(). Python doesn't
really need this, since its attributes are all dictionary-stored.

Btw, as for private data members that are very specific to an
implementation of a class, Ada95 solves this quite elegantly through
packages, which are similar to C++ namespaces. I don't remember if Ada
has language-assisted accessor method support.

Const is overrated but often useful. Given C++'s absolutely antique
object paradigm -- heap-based objects that aren't garbage-collected,
meaning you end up dabbling with pointers *a lot*, or use confusing
reference-counting smart-pointer template classes that go all over the
place -- I like pass-by-reference better.

I'm absolutely annoyed with C++. This is one reason:

  class Foo;

  class Bar
  {
    Foo F;
  };

  class Foo
  {
    Bar B;
  }

This, of course, won't compile -- the class Foo is undefined at the time
Bar is declared. This means that a class A cannot contain a member of
another class B if B already contains a member of class A, unless one of
them stores the member as a pointer reference. This certainly screws up
any reference-counting smart-pointer scheme, or at least makes it bloody
hard to keep simple.

Readability and verbosity are not the same things. Java is at least an
improvement on C++'s readability, but it is occasionally perhaps too
verbose. But not compared to, say, Dylan, which has keywords like
"required-init-keyword"; in spite of this, it's a great language once
you get used to it.

I rather like Borland's Object Pascal myself. It's suitably verbose to
be readable, strict enough to catch most trivial errors in the
compilation phase, statically-typed enough to perform really well, and
just plain likeable. It doesn't have operator overloading, parameterized
classes, multiple inheritance, or synchronized members, although it does
have interfaces, static, abstract, const, and member visibility
constructs. Here's the above snippet in OP:

  type
    Foo = class;

    Bar =
      class
        B: Bar;
      end;

    Foo = 
      class
        F: Bar;
      end;

(And this compiles.)

Indeed, but do I need to remind you that we're still at version 1.52?
:-)

And as for your argument that OSS boosts language implementation, true
in theory, but sitting down with a compiler and changing it, or building
a compiler from scratch, is a daunting and time-consuming task. I have,
certainly, thought about building a native-code compiler for Python. But
no time right now.

Your comments are well received. I hope I can put my own comments to
shame in the future by committing some of my resources to the Python
effort. As for the types-SIG, I've read through Guido's latest proposal,
and found it so-so; I have some comments about the syntax -- which IMHO
is heading in the right direction, but I feel it's still quite
unpolished, like the new "decl" keyword and the very odd, un-Pythonic
"->" operator. Other than that, it looks a lot like I had in mind
myself.

Interestingly enough, I'm discussing this with Jon Udell on his Byte
newsgroups (go news.cmpnet.com). I'll quote something I wrote in this
discussion, slightly edited for clarity:

<quote>
I can't easily tell Zope that objects of type A refers to objects of 
type B (mutual relationships), and that objects of type B should not 
be deletable as long as an object of type A is referring to it 
(referential integrity). The only kind of relationship Zope knows 
about is containment, a parent-child relationship. There is simply no 
other way for an object to refer to another object.

Consider the case of news articles. Let's say articles should be able 
to hold multiple sections of text, as well as images. Assuming we use 
Z Classes and not Products, two solutions come to mind: Either (a) let 
an article be a descendant of Zope's folder or object manager 
classes, and thus contain any such sub-data as objects -- a design 
which currently is the most useful, but which has its shortcomings -- 
or (b) let sub-data exist as objects elsewhere in the ODB, and have 
string attributes on the article object that refer to their names, 
eg. an attribute "Illustrations" of type "lines" containing image IDs 
such as "mayor.jpg", "airplane.jpg" etc. This is obviously ugly -- 
for example, these image objects could be moved or removed and the 
article object would never know. As for dividing article texts into 
multiple sections (page 1, page 2 etc., with appropriate headings), 
this is obviously pretty simple with scheme (a), but in the case of 
(b), the text could exist in one large attribute, and some sort of 
page tagging system might be enforced -- or we could go all the way 
and do XML. So far, with these solutions, we'll survive. Cracks begin 
to show when we start thinking about organizing authors, 
publications, and document flow.

Zope doesn't provide a framework to solve this things. Equally worse 
is that the ZODB hierarchy is so easily polluted with things that 
don't belong there. You end up putting a lot of objects in the root 
folder because they're needed globally -- and anyone who has used 
Zope will tell you that a folder becomes unwieldy and disorganized 
when it grows past 20+ objects. (Case in point: Personally, several of 
my Zope sites have a root-level Utils folder containing oft-used 
External Methods, because they tend to pollute the whole namespace.)
Zope needs a multiple-root, "multihomed" hierarchy. Z Classes must
be able to exist anywhere, not just in the one Products hierarchy.

No, although that's a clever trick. Hey, do it again! :-)

What you cite above may mirror the effect of an enumerated type, but it
doesn't contain any meta-information about the type itself: That is,
FOO, BAR, BAZ are integers. They will fit into any integer expression
and can be passed to any function taking integer arguments. The function
won't balk if you pass a value from another "enumeration". Another
problem with the above is that there is no way to ask Python to
enumerate the values or names in the sequence, because its values are
part of the top-level namespace -- I don't like that kind of namespace
pollution.

Instead, perhaps, this:

  class Enum:
    def __init__(self, Value):
      self.Value = Value
    def __int__(self):
      return self.Value

  class DeadParrot(Enum):
    FOO, BAR, BAZ = range(3)

  def PetShop(P):
    if int(P) == DeadParrot.FOO:
      print 'It''s resting.'

  D = DeadParrot(DeadParrot.FOO)
  PetShop(D)

...But hardly elegant.

And that makes sense to you? I don't know the historical significance of
tuples in Python -- I know the mathematical meaning, but Python tuples
aren't quite it -- but it smells a lot like an interface that has been
fit to the size of the implementation. A lot like, coincidentally, a
procrustean bed. (Coincidentally because the term has popped up a lot
lately; see the Byte thread.)

I think the idea that mutability as a behaviour is distributed among

(No, it would not -- it would effectively give you both "out" and
*pass-by-value* parameters.)

The alternative is returning dictionaries or tuples, is it not? Maybe
I'm not thinking in a Pythonic vein. Maybe

	A, B, C = GetABC()

is more immediately grokkable than

	GetABC(A, B, C)   # assuming these are "out" parameters

Well. Sure it is. Damn, I think you're right. ;-)

Subject: [Zope] Calling a Z SQL Method directly
Message-ID: <6rwvn824kh.fsf@franz.stat.wisc.edu>

I am a little confused about how to call a Z SQL Method directly from
within a DTML document or a DTML Method.

The application is web-based access to a bibliographic database.  I
have one Z SQL Method that looks up publications by author names, or
by words in the title, or by keywords.  I set up a search interface to
that method.  I am now trying to modify the DTML Method for generating
a report from such a query.  I have read the Z SQL Method User's Guide
but apparently I haven't understood it completely.

To make things definite I will describe a simple case.  Suppose I look
up one author's name.  The Z SQL Method is called search_author.  The
columns it returns include the "id" for each reference listing, the
"type", the "year", and the "title".  I have also created a Z SQL
Method called return_authors that takes a single argument "id" and
returns the names of the authors, one per row, in the correct order
for the publication.  Another Z SQL Method, return_journal, also takes
an "id" number and returns the title of the journal, the volume and
number, the beginning page and the final page of the article.

While I am processing the results of search_author in the DTML method,
I would like to be able to call return_authors and return_journal
directly.  It is not clear to me how I do this.  I had hoped that I
could use a dtml-in tag to call these methods while I was within
another dtml-in but either I am misinterpreting the effect of dtml-in
or I haven't got the sequence right.  What I was trying looked like

<dtml-in search_author size=50 start=query_start>
 ...
        <tr>
          <td><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
	  <td><dtml-in return_authors start=query_start>
                  <dtml-var name>;
              </dtml-in></td>
              <dtml-in return_journal_info start=query_start>
                  <td><dtml-var title></td>
                  <td><dtml-var vol null=""></td>
                  <td><dtml-var bpg null="">-
                      <dtml-var epg null=""></td>
              </dtml-in>
        </tr>
 ...
</dtml-in>

I was hoping that the <dtml-var id> from within the <dtml-in> loop
would be propagated to a call to return_authors or to return_journal.

I understand that I can use a URL to call the Z SQL Method but I am
hoping I can do it "inline", as it were.

I would appreciate any suggestions.

Douglas,

ZSQL methods can be passed arguments.. e.g.

<dtml-in expr="return_authors(id='123')">
...
</dtml-in>

In the case that the 'id' value you want to pass in comes from REQUEST
or another namespace, you can use it:

<dtml-in expr="return_authors(id=id)">
...
</dtml-in>

The _.render() method will do what you want:

  <html><head>....</head>
  <body><table><tr>...

  <dtml-var "_.render(this())">
  </tr>
  </table>
 ....

you need a folder called "import" in the same directory as your zope
installation.  Then go into zope, click "Import/Export" tab at the top,
and enter 'filename.zexp' in the "Import file name" field.

then click "Import".

That should be it!

I'll take a stab at this:

Quantity of data doesn't tip the scales towards Zope or SQL.

If you have small units of data that change frequently, SQL, using a
non-transactional storage like BerkleyStorage, or packing frequently are
all reasonable approaches.

If you have a number of large (multimegabyte) files, the filesystem is
probably the best place for them, with something like LocalFS.  Also
nice because you can have a "real" ftp server serving the files, but
still use zope to reference them.

If your data expresses several many->many relations, a relational
database may be the solution, but don't underestimate the power of
Zcatalog. for data expressing one->many relationships, ZODB rocks.

In your example, I would use the ZODB because emails are always
hierarchical, and use Zcatalog to let people slice & dice it. The
articles would depend on what views you need to put on them and what
metadata you want.

You can also do some super neat stuff with ZODB+SQL, as the very
illuminating 
Zope Question : Virtual folders / URL's thread is illustrating.

I've done some really neat things (like securing the management screens)
with SiteAccess that I couldn't dream of doing any other way.  I've
never seen SiteAccess perform in any unadvertised fashion.

Anything that lets me have less than hundreds of zopes is a good

Let's say I have a TinyTable populated with some data.  I have a DTML
method that displays it all pretty like.  What I do *not* want is
someone seeing the TinyTable itself, so I give "access contents
information" to anonymous, but deny "view".

AFAIK.

This might be possible. I'm checking the IMAP code. Possibly we'll need
to use EXAMINE on some spots instead of SELECT.
Maybe there's a race situation which would explain why it works for some
and for some not.

If heavy copy operations are involved then that would support the race
situation.
We use debian, too, so we'll try to replicate the behaviour here, too.

Cyrus is better scalable and has cached indexes. furthermore mails are
stored in individual files instead of in mailbox files.

Use the DateTime Object, in python:

Py$ from DateTime import DateTime
Py$ DateTime() > DateTime('Jan 1, 1999')
1
Py$

in DTML:

<dtml-if "_.DateTime() > _.DateTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Calling the DateTime object with no arguments means 'now'.  It accepts a
number of different date formats.  I just made this one up and it
happily accepted it.

In DTML, _.DateTime is synonymous with the global value ZopeTime.  So
the Second example is equivalent to:

<dtml-if "ZopeTime() > ZopeTime('Jan 1, 1999')">
  True.
</dtml-else>
  You should never see this unless the universe reversed itself.
</dtml-if>

Hi,

we started a new service for our online newspaper, that is served by a Zope
server. (http://rz-anzeigen.de) We currently experience the problem, that the
machine serves really well and also during the high traffic times. But
sometime in the early morning the Zope process crashes. Now I like to know if
it is possible to get some more specific out from the Zope server when it
crashes. Can I activate some kind of logging to monitor this, or something
else that helps me to deal with this? Or is my only option to start the Server
    form the shell and see what traceback I get?

Bye, Oliver

I have this

    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltecimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

IIRC the logic that puts in BASE tags ignores the port number.

It was a simple change (removing an if section) somewhere to fix it.

I did it in old bobo-based app so it may have changed by now.

Jo,
Thanks for your C expertise.  The changes you mentioned were all that was
needed to get the MySQLmodule to compile and the MySQLDA to work.  I now see
the ZMySQL Database Connection in my list of available items in Zope!!! (big
smile).

I will eventually want to get Andy Dustman's MySQLdb connection to work,
because it is multi-threaded.  But for now I will stick with what works,
learn how to tie Zope to MySQL and THEN go for the upgrade to MySQLdb.

Anyway, thanks again for taking the time to solve my problem.

Eric.

Subject: [Zope] Problem with Images
Message-ID: <LOBBJLLPAJLLCKOOOAGFOEADCCAA.gelhaar@compuserve.com>

I've got a problem with the image class. I use Zope 2.1.4 (downloaded from
http://yyy.zope.org/) with Windows 98 second edition.
Let me give an example:
1. I create an image object head_1 and upload an image "cat". Everything is
fine.
2. I upload an other image "dog". Almost nothing happens. The image is not
there. But something has changed: The size properties. What ever I do, I do
not get the right picture, I will see always "cat" but always in different
sizes, the size from the last uploaded picture.
But that's not all.
3. I delete the image object head_1
4. Create a new one, let's say head_2 and give it an image "dog". I see dog.
5. But now, when I rename the image object from head_2 to head_1 I will get
again the old picture "cat".
This scenario is always the same, regardless what I do:
* shutdown the database in between
* clearing the undo buffer
* new installation
* hide the python installation dir
* delete the database

I played around with the lib/python/OFS/Image.py. But I experienced enough
with Zope thus I know Python. What ist wrong with me or the Image class.

Help

I've been asking this list the very same question for quite a while.  There
are a few debug How-Tos that may help, but it's all very dependent on you're
configuration as to how much extra work will be necessary.  Can you give me
more details of your configuration?  What are you using for connection, are you
going through Apache, if so using what service (PCGI,FCGI,HTTP_Proxy)?  

We have several sites up and running with Zope and have found that when there
is /manage activity occuring during a time of moderate traffic we have frequent
Zope restarts, it can't stay up more than 5-20 minutes.  To date I've found no
reliable method of tracking what is causing these, though I've created a bunch
of monitoring and debuging tools to try.  These tools are not written up yet,
but I'd be happy to send out an explaination if you would like.

It is also very easy to create code that will crash or loop the Zope server,
these are easer to find since usually as soon as the object is called Zope
reacts adversly, crashes, slows, etc.  The problem using logs for this is log
entries are usually written post completion.

Good luck.

This is almost certainly because your browser has cached the image.
Try clearing your browser cache.  Or better yet (because sometimes
clearing the cache on some browsers doesn't seem to completely
clear it), try loading the thing from a browser that hasn't
looked at that image before, and you will probably see the correct
image.  At least, that's how it worked for me when I ran into this.

Do you know about STUPID_LOG_FILE?  Put that variable in your
environment when you start Zope, and Zope will write some stuff
to the specified file.  This info may or may not show something
when Zope crashes, but it is worth a try.

How about 
<dtml-in sqlQuery>
<dtml-var sequence-lenght>
</dtml-in>

? 
There also some more statistics over the columns. Please refer to 
the manual for more.

Subject: [Zope] How do you Restrict ZServer socket connections
Message-ID: <14540.5250.770668.306712@erdos.totient.co.uk>

Hi 

I've followed anser's How To on "Apache and ZServer (NOt CGI)"
and now I have Zope served thru Apache via module ModProxy and the
SiteAccess Zope Product.

Fine, But Now I want to make Zserver only accept connections from
a set of known IP address (ie that where my apache server runs)

Any ideas how you do this? I can see there are options to say
which ports it listens on but no mention of restricting the
IP addresses it allows to connect.

Thanks

Jon

Ive been having a similar problem. The problem lies not with Zope, but with
your browser and its cache. As long as you are trying to retrieve the image
from the same URL, your browser will grab the cached image rther than the
one from Zope. I havent delved into this, but I think adding some content
expiry info to the 'view' tab might be necessary. Either that or change your
browser settings.

You can connect to the database from the mysql command line utility?

ZServer does not do this interally, however there is a very secure and
popular program called tcpwrappers that does.  Your system probably
allready comes with tcpwrappers.

How to configure it to work with ZServer I don't know, but it shouldn't
be hard.  Consult the tcpwrappers docs.

If you are using Linux, this job is best done with
the firewall itself (like ipchains.) Otherwise it
is not very secure.

That being said, inside Zope itself, you can put in your
index_html (or equivalent)

<dtml-if "REQUEST.REMOTE_ADDR != '127.0.0.1'">
  <dtml-return "''">
</dtml-if>

Of course, you can return a nasty message, or redirect
the request to some other web addresses by using
<dtml-var "RESPONSE.redirect(...)"> :) If you are using
SiteAccess, you can put a hook at the root folder to
bounce off anyone that you don't like.

The REQUEST variable holds other environment variables
that might be of your interest. You can either use

<dtml-var REQUEST>

to print out the variable content, or simply append
/REQUEST to your URLs when you are browsing a Zope
site:

http://your.site.name/yourfolder/yourpage/REQUEST

Subject: [Zope] Generic User Folder Gotcha
Message-ID: <20000313105937.B4444@bob.sesgroup.net>

Just thought I'd let people know about a small gotcha in the GUF.

If you do not have a user folder in the root directory and then create
a GUF in a subfolder using cookie-based permissions it will lock you
out of that folder.

GUF works fine in this situation if you use basic authentication just
not with cookie based. The problem is that in cookie based authentication
method it never checks whether you are the super user or not. It works fine
if you have a user folder in the root becuase it then goes and checks it.

I tried some code to get around it but didn't really have time to fix it
esp when it is trivial bug/feature? to get around.

Anyway just though this might save some people some time along the way.

Oh and thanks to Zen GUF is a fantastic product !

Cheers,

Benno

Take a look at the dtml-try tag in the dtml documentation.

Message-ID: <B059671903C6D211A0D500C0F0301C792B2697@kubrick.mop.no>

Like so, for example:

	<dtml-var "MyDate.toZone('GMT')" fmt="ISO">

Date-time math is very simple with Zope's DateTime objects. DateTime
supports fractional, C-type clock values -- 1.0 is one day, 0.5 is half
a day, 1 / 24.0 ~= 0.0416 is one hour. So,

	<dtml-var "(ZopeTime() + 1).toZone('GMT+5')" fmt="ISO">

gives you the time tomorrow, adjusted to GMT+5. You can use named time
zones such as "US/Eastern".

Helmut,

I doubt it.  It's probably a username/password/databasename issue.

My suggestion would be to set up mysql to accept a null login (no
username, no password), create a database in there called "test" and
connect with the connection string "test@localhost"

I don't think this is a bug in WU or a concurrency issue, I think it's a
funky design decision in imaplib.py

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import imaplib
>>> server = imaplib.IMAP4('X.X.X.X')
>>> server.login('michel', '******')
('OK', ['LOGIN completed.'])
>>> server.select('Public Folders/Mailing Lists/Zope Folder')
Traceback (innermost last):
  File "<pyshell#8>", line 1, in ?
    server.select('Public Folders/Mailing Lists/Zope Folder')
  File "C:\Program Files\Python\Lib\imaplib.py", line 468, in select
    raise self.readonly('%s is not writable' % mailbox)
readonly: Public Folders/Mailing Lists/Zope Folder is not writable
>>> 

server in this case is a Exchange box.  There is nothing in section
6.3.1 of rfc2060 that says this should fail.  The imaplib authors
however seem to have felt otherwise, which is why there is an optional
second argument to IMAP4.select():

def select(self, mailbox='INBOX', readonly=None):

Passing a true value to the readonly argument will allow you to select
the mailbox, as shown:

>>> server.select('Public Folders/Mailing Lists/Zope Folder', 1)
('OK', ['964'])
>>>

Try the DebugLog, this is an as yet undocumented feature of Zope:

http://www.zope.org/Members/mcdonc/HowTos/DEBUG-LOG

This will show various state transitions of requests.  This helps
pinpoint, for example, if your problem is a ZServer or an application
issue.

Subject: [Zope] Python or C Library error?
Message-ID: <NDBBLBELNHAPHBBCOIFDKEMGCBAA.ewalstad@energywright.com>

Well, I thought I had it working...

I am trying to get MySQL to work with Zope.  I installed ZMySQLDA and was
able to make a connection to a database.  I was even able to make an SQL
method that added records to the table.  However, when I added a method to
lookup a record in the table, I get the following error when I "Add and
Test" it from Zope:

Error, exceptions.ImportError:
/usr/lib/python1.5/site-packages/_mysqlmodule.so: undefined symbol:
Py_InitModule3

This is the same error I got when I tried to install MySQLdb.  That's why I
tried to install  MySQLDA instead.

However, I can't tell if this error stems from C or from Python.  I don't
know much about Python (the book I ordered isn't here yet), but it looks
like the error is starting there.

If anyone has run into this error before, or has a clue as to how to fix it,
please let me know.

OR, if you have a working Zope/MySQL combo and wouldn't mind sending me a
copy of your '_mysqlmodule.so' binary, maybe that would do it?

Thanks,

Eric.

This is kind of a distressing message Tony, we'd very much like to see

Yeah ;) But whats with comparing wether we are between hour xx and hour
yy 
every day? Or even between 0:00 and 1:15 every day...
This comes up with very strange hassle with DateTime() and strings and
int() 
and so on...

Or is there a better way?

I've never used MySQLDA without MySQLdb.

I would try to follow the steps in the howto that deals with installing
mysql (including the steps for installing MySQLdb) in order to get the
thing working.

It sounds like you couldn't compile MySQLdb because you didn't have the
right libraries for MySQL.

I saw that, too, but wasn't sure if it behaves the same, because a few
lines further up if that parameter is true then it uses EXAMINE instead
of SELECT. I haven't made it yet back to the RFC's to check in detail
what the exact difference is between the two. If EXAMINE is OK for 
write operations as well, then that would be fine. But it sounds like
it's intended for following read only operations only. I'll check it
out...

Cheers,
Ryan

DateTime works at one one-thousandth of a second resolution.  Hours and
minutes are no problem.

No hassle that I can see, no more so than any other kind of object that
would do this.

There's mxDateTime, which I believe works similarly to DateTime.  I
don't think one is any 'better' than the other.

Subject: [Zope] RFC: Flaws in Structured text
Message-ID: <B059671903C6D211A0D500C0F0301C792B2699@kubrick.mop.no>

I would like to outline a few problems, based on
observations of real-world usage, with Structured text.
Comments are appreciated.

As much as I like the format, the current syntax is either
too loose, or the transformation logic too dumb, resulting
in text that does not come out quite as expected. There are
workarounds for all such problems, but authors and editors
aren't aware of them, and continually make the same mistakes
over and over again.

Here are a few gotchas:

- Lines starting with the text number-dot (eg., "1.") are
considered to be bullets.

  Problem: In other languages, and sometimes in English,
  this is a valid non-bullet introduction. In Scandinavian
  languages (Norwegian is the language of my country), for
  instance, "1." is an oft-used way of spelling "1nd" or
  "first" ("2." for "2nd" or "second", and so forth). My
  experience is that this occurs frequently.

  Solution: Avoid transforming such paragraphs into bullets
  when they occur adjacently to valid non-bullet sentences,
  and only apply the transformation when the number is
  higher than the preceding paragraph. Validate the number
  itself -- today you can write
  
    43423. Something
    
    24324. Something else
    
  and it's still transformed into 
  
    <ol><li><p>Something</p><li><p>Something else</p></ol>

- Lines starting with dash-space (eg., "- The") are also
interpreted as bullets.

  Problem: As with number bullets, this clashes with non-
  English conventions. At least in Scandinavian languages,
  quotes are often given using a preceding dash. Here's an
  actual example, translated to English for clarity:

    - Pooh, said Rabbit kindly, you haven't any brain. - I know, said
Pooh humbly. 

  Solution: Make this feature optional.
  
- Em dash sequence ("--") usage clashes with definition
lists.

  Problem: People, including me, frequently use an ASCII
  form ("--") of the em dash ("-"), in the absence of this
  character in the 7-bit ASCII character set. (Actually,
  what *I* want is an en dash, which ISO provides.) This
  transforms into a HTML <dl></dl> list, even when the dash
  occurs late in the paragraph.
  
  Solution: Only transform paragraph to definition list if
  the dash sequence follows the first, dot-terminated
  sentence, like so:
  
    This is a definition term. -- and this is the definition
    itself.
  
  Not sure whether this is ideal. It would likely break old
  stx documents. Perhaps a "force literal" control character
  can be introduced, like the "\" token used in Python, Perl,
  C, etc.
  
  Note to self: There ought to be a way to transform such
  poor-man's dashes into en/em dashes, and quotation marks
  to "smart" quotation marks.

- Link transformation into HTML anchors tags is poor, or at
least too rigidly parsed.

  Problem: Some examples of links that do not work:
  
    The document (found "here":http://www.zope.org).
    
    <dtml-var "'This is a \x022link\x022:http://www.zope.org/'" 
      fmt="structured-text">, 
   
  I'd love to give cite other annoying cases I've come
  across, but I don't remember them. ;-)
   
  Solution: Tolerate parantheses, and accept that URLs that
  are terminated with end-of-line. Provide better syntax for
  specifying URLs, such as this:
  
    A product called Zope (http://www.zope.org) can be found
    on the _Zope site_ (http://www.zope.org).
    
  which would be transformed into:
  
    A product called <a href="http://www.zope.org">Zope</a>
    can be found on the <a href="http://www.zope.org">Zope
    site</a>.
  
- Structured text code should not wrap transformed text in
paragraph tags (<p></p>), or should at least make this
wrapping optional.

  Problem: I often display stx in places where a new
  paragraph creates unnecessary vertical padding that
  violates page design -- for this purpose I have been
  forced to write a simple External Method that removes the
  offending paragraph tags. IMHO, this ought to be
  unnecessary.

  Solution: Provide necessary option.
  
- Structured text code not available to DTML.

  Problem: The code is only available to External Methods
  and products. DTML can only get at stx through dtml-var's
  fmt attribute.
  
  Solution: It would be swell to have an _.stx() or
  StructuredText() construct.

Define "top-level namespace"?  This is one of my favorite things about
Python.  You get the behavior you want below *for free*, because modules
are done the Right Way (tm).

'-- spam.py ---
| FOO, BAR, BAZ = range(3)
| 
| class Spam:
| 	def __init__(self,foovar):
| 		self.var=foovar
`--
'-- eggs.py --
| import spam
| can=spam.Spam(spam.FOO)
`--

Alternatively, if eggs.py uses spam.py heavily, and is closely integrated
with it:

'-- eggs2.py --
| from spam import *
| can=Spam(FOO)
`--

I use both styles -- and you can choose!  Clean namespaces, or terse
syntax -- voluntary namespace pollution.  You can even be selective (and
this can really be fun) with expressions like:

'-- eggs3.py
| import spam
| FOO=spam.FOO
| Spam=spam.Spam
`--

if you're heavily using FOO, but not BAR or BAZ in eggs ...

For some strange reason, although they have come under lots of fire,
tuples make perfect sense to me.  They don't seem to confuse new
programmers much, either, since I've been introducing lots of people to
python...

For example; lists used as dictionary keys, if mutable, would have all
sorts of confusing effects.  Class instances, being explicitly references,
don't have this problem; but if you pass a list in as a dictionary key,
change the list... what should happen?

class A: pass
x=[]
q=[]
# you may want to think of that as
# q=copy(x)
# instead
y={}
z=()
a=A()
b=A()
y[a]='a'
y[b]='b'
y[z]='z'
# broken, but to prove the point
y[x]='x'
print y[q]

The same thing goes for strings... I dunno.  Type-defined mutability makes
a lot of sense to me.

Doesn't that just *look* nice?  This is certainly how I'd write this
happening in pseudocode, and I was overjoyed to find that python did it
automatically.

> is more immediately grokkable than
> 
> 	GetABC(A, B, C)   # assuming these are "out" parameters

This style is BAD BAD BAD.  I don't like having my variables manipulated
by functions, if they're mutable... but it would be even WORSE to have the
symbols actually changed!  Nonsense like this contributes to some of the
least readable code I've ever seen in C and C++ ... ugh.  I *wish* you
could return tuples in C++ =)

(The worst part about this is that SOMEtimes, calling a function would
create new variables for you, or reassign them, and sometimes it
wouldn't... ugh.  I don't like it.)

> Well. Sure it is. Damn, I think you're right. ;-)

Glad you see it that way =)

(Tuple unpacking is also brilliant, by the way, for constructs like
	for key,val in dict.items()
)

Subject: [Zope] efficient internal redirect
Message-ID: <38CCA329.9A3754CC@open.ac.uk>

I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

Not exactly. I suggest you read it again. What you and Martijn propose
gives _no_ type safety at run-time. That's just like using constants,
except they're wrapped in a module namespace.

And they do pollute the top-level -- that is, the module-global --
namespace. Let me know when you find out how to enumerate the values in
an enumerated type, and how to convert an enumerated value back to its
name -- and then I might think you're up to something.

Similarly to C++, Python classes behave like namespaces, so you can
avoid pollution by wrapping the values in a class:

	class Foo:
	  FOO, BAR, BAZ = range(3)

and so you can enumerate the values as attributes.

True. However, personally I prefer lexical scoping -- which I hear is
under consideration for Python 3000 -- to the weird three-level
namespace that Python provides. Having to import "global" variables
because the compiler optimizes assignments is way uncool.

I'm not contesting that dictionary keys should be immutable, but rather
that lists and tuples are nearly the same things (*nearly*, but not
quite) with the crucial difference that lists are mutable. Why? There's
no real design here. The only scientific answer to that question is
"Because."

Take a look at my Redirector product, which does this very thing -- it
lets you create Redirector folders which, when rendered, simply redirect
to somewhere else.

It uses regexps to let you apply patterns, such as saying that "/Parrot"
should redirect to "/PetShop" but than "/Parrot/Fish" should redirect to
"/Aquarium". It allows 1:1 redirects as well as many:1 redirects.

Dylan Jay has derived an improved version that supports simpler group
replacements using replace(). Both versions are on zope.org.

I agree with your points, but what is more important for me,
is that the rendered HTML is syntatically correct

* this is an item

* another item

* a third item

currently renders as :

<ul>
<li><p>this is an item</p>
<li><p>another item</p>
<li><p>a third item</p>
</ul>

which is not very slick.. I'd prefer a forward-compatible
list-rendering format, complying with HTML4.0 and XHTML,
looking like this :

<ul>
<li>this is an item</li>
<li>another item</li>
<li>a third item</li>
</ul>

Anybody who has tried to make Netscape4.x understand CSS
without properly closing tags will understand my point..

Thankyou for replying

Whilst this is I'm sure a useful mechanism redirecting
whole folders is overkill for what I need to do.  I have
many links into a tree and wish to have a very simple format
for the external links and an internal mapping mechanism
which maps each link to its real URL.  My question remains.
What's the most run-time-efficient (not development-time-efficient)
way of doing it?  I think you gave me the quickest development
route which is not quite what I was asking.

I agree with theese purposes on Structured Text...

I would like to be able to write simple tables with Structured Text.
Something like :

| FirstName | LastName | Age |
| Olivier | Deckmyn | 25 |
| Guido | Van Rossum | 32 |
| Linus | Torvald | 29 |

That will build a simple table :
<table>
  <tr>
    <td>FirstName</td><td>LastName</td><td>Age</td>
  </tr>
  <tr>
    <td>Olivier </td><td>Deckmyn</td><td>25</td>
  </tr>
  <tr>
    <td>Guido</td><td>Van Rossum</td><td>32</td>
  </tr>
  <tr>
    <td>Linus </td><td>Torvald </td><td>29</td>
  </tr>
</table>

Customization could be done with CSS...

Why can't they be the one and the same? Redirector is fast -- I suspect
the difference in speed between Redirector and something else would be
negigible.

Remember that a Redirector folder is in itself just an index (of
regexps -- it's not hard to wire the lookup so that, if the term is not
a regexp, then it will use a dictionary, which is a lot faster). It does
not need to contain anything, and you need only one Redirector folder to
accomplish what you ask for. Let's say you have three areas that others
link to: Downloads, Registration, and News. First, create a Redirector
folder called, say, /Targets. Then edit the folder's redirection
mappings to look like so:

	From                   To
	Downloads              /Downloads
	Registration           /Snark
      News                   /News

Notice that the Registration name maps to /Snark -- this to illustrate
the mappings have nothing to do with the *names*. Now, having done this,
you can access your mappings like so:

	http://www.myserver.com/Targets/Downloads

which will redirect to

	http://www.myserver.com/Downloads

Isn't this what you want?

Shouldn't that rather be

<ul>
<li><p>this is an item</p></li>
<li><p>another item</p></li>
<li><p>a third item</p></li>
</ul>

After all, we *are* talking about paragraphs here. I happen to like --

Subject: [Zope] getting port number into URL - was where port num gone
Message-ID: <38CCBEF7.BF8534E5@open.ac.uk>

I'm sorry to ask this again but there must be a way of
getting a port number into a url without being explicit
about the address.  There has to be because absolute_url()
does it inside a tree.  I just don't know what I can use
and the expression syntax to do so.

I have this

root
    ltscimages
        someimage
    somefolder
        somedtlmdoc

and I'm running both apache and zope.  Some pages
get served zope-->apache and some direct from zope.
ZServer is running on 8080.

Within somedtmldoc I want an image from ltscimages.
This code

<dtml-var "ltscimages.someimage">

produces a reference
to the image but without the port number.

In the ouput html I want

http://host:8080/ltscimages/someimage

but I get

http://host/ltscimages/someimage

I can work around this by serving the image via
the zope-->apache method but that's crummy - I want
only to use apache when I have to because of the
efficiency effect.  Putting the port in explicity
is also crummy because its less transportable.

How can I either 1. always get the port num in
or  2. get the port in if its not
the default 80.

Elswhere in the same code absolute_url() does this correctly
for code inside a tree.  Would there be a way to use this here?

Sorry for so many newbie q's.  I promise I'll give back when I can.

Andy

.. not necessarily.. the <p>s imply a paragraph of text,
which is not necessarily what is contained in the <li>..

i agree that in most cases the visual result is better with
the <p>, but this should really be taken care of with css.
As far as possible, presentation and content should be
separated...

the <p>s would be ok with me, if we just got the <li>s to
close correctly, but i don't think they should be there if the
reason is purely aesthetic..

Imho closing the <li>s is all we need -- adding padding with CSS works
with the latest browsers, but we still have non-CSS browsers. As much as
I prefer pure, CSS-enriched HTML, it doesn't work all that well in "real
life". Not yet, anyway.

I confess, what you have is a very good idea.  The reason I'm hesitating
is because there won't be two or three areas and its wrong to call
them areas.  They will be single documents and a little bit further down
the
road there may be hundreds of them needed and not in any homogenous
flat structure but at different places in a tree.  Also,
I really do need every last inch of speed out of this part.

Hardwiring your code to use a dictionary looks like a good idea for
the present.

Some questions:

1. does your product redirect back to the client or within zope?

2. assuming it were hardwired as you suggest what would be the runtime
cost over just having folder methods in zope do the redirection?

3. I haven't touched python for 2 years now (though I did use it a lot
then) - I'm very rusty.  Could you supply a patch to hardwire in a
dictionary
instead of the regex code?  Assuming 2. is satis this *could* be a good
answer.

4. still looking for an answer to my orginal q - what's the most
efficient way?

One of myw own - words in single quotes 'like this' should NOT be turned
into code examples.  Most people do not write code examples in their texts.

Or add the whole special_formats dictionary available in PythonMethods to _.

In general, strucutred text needs a complete rewrite to make it extendable
and customizable.  Using the current structure you end up commenting stuff
out and rewriting sections of the code, which is not a very good way of
working.  But I doubt DC have the time for that.

Why not derive a specialized version of my product ("Redirector Method")
that descends from not Folder, but SimpleItem? If each such method
represents only a single "mapping", you get what you ask for.

Of course, if you have plugged your Zope into Apache, then it would be
more efficient to use mod_rewrite anyway.

> Some questions:
>
> 1. does your product redirect back to the client or within zope?

Yes. It forces an HTTP redirect. I don't if Zope is re-entrant; that is,
whether you can emulate symbolic links by passing the request, modified,
back into Zope.

> 2. assuming it were hardwired as you suggest what would be the runtime
> cost over just having folder methods in zope do the redirection?

Not sure if the word "hardwired" is correct here. After all, what I just
described to you in the previous email was not about changing the
product itself -- that's hardwiring -- but changing the parameters to
the product's *folder instance* -- that's Zope. ;-)

What I suggested about using a dict for non-regexp mappings does not
involve any hardwiring, either -- I meant patching the product to
support dicts *in addition* to the existing regexps. Basically in the
folder's management interface you'd simply specify whether a mapping
used a regexp or not.

Runtime cost: You would have to time it. Marginal, unless you're
expecting a gazillion hits.

Let me think about it. I'm pretty busy -- perhaps Dylan is up to the
task, he did the previous patch.

mod_rewrite.

You know, I have a similar problem... I have 6 aliased IP addresses. 
I'm running 3 zopes, at the moment.  All of them have been told what IP
address to use.  The first can listen to 8099 and 8021 no problem, but
the rest of them complain.

if I do -f '' and -m '' everything is fine, but they're all listening to
8080, so what's the gig?

netstat shows localhost:8099 and *:8021, and the same for the other
server that I set to 9023 and 9023 respectively.

Does Zserver listen indiscriminately on ftp and monitor?

But still people do change compilers! People have added garbage collecting
to the Python interpreter, list comprehensions, and there's the whole huge
stackless effort. I'm sure there are more examples in the past, for Python.
Without open source, this wouldn't have happened.

I've thought about it too, and no time either. Maybe we should get

That's indeed a shortcoming in Zope as it stands, but that's not an

That's true, but please note that C's enum is used successfully and

I agree it might be nice to have a more elegant way to deal with
enumerated types. Perhaps as a result of static type checking extensions?

Well, it makes sense to disallow mutable dictionary keys. You asked why
have two kinds of lists, I tried to give the answer. Lists and tuples have
been moving towards each other in recent Python versions, though; I believe
originally only tuples supported unpacking. If there was somekind of
mutability system in place that could replace tuples.

It's cute though, as immutable objects behave like pass by value objects
do (except those darn tuples again, if they contain something mutable like
a list or an instance). I think that's a neat idea.

Python has a syntax for that:

You have misunderstood what I'm asking completely (probably my fault).
I am using apache and zope, some pages served via the zope-->apache
route, some
directly from Zserver (faster than going via apache) and some just with
apache. Some addresses are already being rewritten by apache - that's
not
a problem.  The mechanism I am seeking to use is just something like

<dtml-var destinationPage>.

Since this doesn't go back to the client between it has to be faster
than going back to the client and doing another request for these
particular
pages (which are in this database anyway).

Please can people reply to my original post without recommending
the redirector product.  I've reproduced the post below in the hope
someone can answer it for me.  Please don't reply telling me how
marvellous the redirector is - yes its a good idea but its not
what I'm looking for here - I'm just looking for some help to
know what's the fastest method and how to code it.

Original post
-------------
I have some pages within zope which are linked
to externally (from non-zope pages).  I want
to have some sort of internal index so that I can
move the zope pages around completely within zope
(move a page and change its index) without breaking
or having to change the external in-pointing links.

This mechanism will come into play for nearly every
page in my system so I'm looking
for the most efficient code to do this.

My thinking about possibilities for the index :-

methods in a folder
properties of a folder
properties of a dtml-doc
some other sort of data structure

For the redirection its obviously more efficient to
do it something like dtml-var rather than redirect
back to the client but (as my other posts show) I'm
often really struggling to get my object references
right (only partial understanding - looking forward to
better documentation) I'd appreciate some help here
too.

What's the most efficient way?

Andy

[snip]
> You have misunderstood what I'm asking completely (probably my fault).

If I were you, I'd definitely go over that original post of yours again
and consider how it can be rephrased -- because from what you say, this
is how I see your problem:

1) Pages within Zope
2) External sites or pages that link to these pages
3) You'd like the underlying pages to be separate from the URLs to which
these external pages refer, so that you can move the actual data around.
4) You want this to perform really well.

From this specification, it sounds like, aside from the marginal
performance loss incurred, you should be able to make do by using plain
old HTTP redirection. Did I get any part wrong?

You could use a kind of hub method like so:

<dtml-let Mappings="{
  'Downloads': PARENTS[-1].Downloads,
  'Foo': PARENTS[-1].Bar,
  'Snarf': PARENTS[-1].Smurf.Snark
}">
  <dtml-var "Mappings[REQUEST.Where]">
</dtml-let>

Assuming the method is called /Hub, then you can invoke it like so:

	http://www.andysserver.com/Hub?Where=Snarf

and it will display, in this case, the object "Snarf" in the root-level
"Smurf" container. While this works (you can also use a TinyTable
instead of a dictionary), this has a few gotchas, such as causing
trouble with proxy roles. No HTTP redirects, but not as elegant.

Oh, and did I mention how absolutely marvellous the Redirector product
is? ;-)

Subject: [Zope] manage_delObjects problem
Message-ID: <3.0.1.32.20000313085541.0068c54c@bizux.net>

Can anyone give me any insight as to why the below URL doesn't work.

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?id=8185

After the URL is visited the manage screen comes up and tells me "No Items
were specified!" 

So I am a little confused as to why there is no item specified, when I am
sending the 'id' number with the URL, and will the activation of this
hyperlink take me to the manage screen or just delete the object and leave
the user at the page where the hyperlink was requested from.

Best regards, 

-M.

Yes.
Plain old inclusion (like #include in C) would work faster
because it doesn't go back to the client in the same sense
as HTTP redirection.

There is some way of doing this in dtml, I know because
I had something working at one point but I can't remember
what it is.  I do remember it only worked if the objects
that were redirected to (equivalent of included) were methods
not documents.


<dtml-var "whatever.whateverelse.object> gets the right object
but it doesn't get rendered.

This will imply some parameter to define whether you want headers or not
as not everybody uses them. Unless we can come up with some clever (but
visually pleasing in ASCII) format. 

Alexander also mentioned he does not like the <p> elements inside <li>
elements but IMO are required in cases where there are more than one
paragraphs in an <li> element. Unless we default single paragraphs in <li>
elements to non <p>, but then we break consistency.

I suppose a complete rewrite of stx is in order using a more modular
interface. For example I was thinking of one class per structure element
with the appropriate input method to receive the stx text, and a number of
output methods to produce a variety of formats, html,pdf,rtf etc. This is
the approach I followed in the Table patch but it is also slower. The
original stx was designed with performance in mind.

One suggestion I have (and it would be relatively easy to implement) is to
cache the rendered document in a volatile attribute attached to the
DTMLmethod/Document that contains it, together with a simple checksum of
the input text. Then we would be free from the performance constrain at
least to some extent.

Hi,

I have the following access rule:

<dtml-if "_.has_key('virtual_host') and REQUEST.environ['HTTP_HOST']==virtual_host">
 <dtml-call "REQUEST.setURL(path='/')">

The idea being that if a folder represents a virtual host (see the thread 'REQUEST vraible methods'
on this list for background...) you can just give that folder a virtual_host property which the
above rule checks for, and if it matches that in the header, if sets the base path to '/'.

However, if I try and access any folder with this rule in it, I get challenged for authentication
and get 'Authorization failed' no matter what username and password I use, including the root ones!

What is going on?

Would using re (so it can take advantage of multithreading) make up for a
more complicated rendering engine?

This wouldn't work in all cases - consider <dtml-var ZopeTime>, where the
output changes every time it's called.  If an object contains only
strucutred text then you store the rendered text too, and update it every
time the input text changes - the PTK has an object that does this.

manage_delObjects expects 'ids' - which is a list - as parameter. So,
try

http://diis/inventory/outofstock/OOSStorage/manage_delObjects?ids=8185

or:

No, the user will be directed to the management screen. To prevent this,
you can either create a dtml method or you put something like:

<dtml-if delobject>
  <dtml-call "manage_delObjects(delobject)">
</dtml-if>

into the calling page and change the link to:

Hmm I hear the new re module of python1.6 is fast .. so a migration to re

If a block of structured text contains dynamic content then you are right,
caching won't work, but in many cases structured text documents contain
only static text. It does not harm to cache unless you have many stx docs
and little memory. I haven't checked PTK yet but in Zpdf Document the
rendered output is cached in a volatile attribute together with a fast
checksum on the input text. Works quite well and ZODB takes care of
garbage collection during object deactivation.

Hi,

I am new to Zope, and having some trouble.  I imported my directory
structure into zope, but zope doesn't recognize server side includes...for
example, 

<!--#set var="TITLE" value="Some title here"-->

I get the error: Unexpected tag, for tag ......

Is there a way to get zope to recognize server side includes?

Thanks,
Jessica

Referring to server side includes, I probably should have put that this
line was an error as well: 

<!--#include virtual="/include/header.html" -->

Subject: [Zope] mange_changeProperities external method
Message-ID: <3.0.1.32.20000313105947.0068de3c@bizux.net>

I have an a form in which the user can edit an instance of a ZClass and
resubmit the data. This data is to be used instead of the data that is
currently listed within the properties of said object.

After submitting the change I get this error:

Error Type: AttributeError
Error Value: 'string' object has no attribute '_properties'

The code that it is referring to is:

def editTaskProperty(self,REQUEST,RESPONSE):
  taskobject = self.taskstorage.REQUEST['task_id']

  for p in taskobject._properties:
    taskobject._setPropValue(p['task_title'], REQUEST['title'])

Can anyone give me any insight as to how the proper method of changing the
properties listed on an instance without the user catching any wind of the
management interface?

Best regards, 

Mark

You can do it in a DTML Method (very similar in an external method too)
like:

<dtml-call 
"MyZclassInstance.propertysheets.Mypropertysheet.manage_changeProperties(REQUEST)">

The reason I was using the external method was to avoid the user from

This should work, is 'The Right Thing'.

If you are using a DTML Method, then it will be a method *of the
folder* containing the method. DTML method's dont add a namespace of
their own, so <dtml-var title_or_id> is supposed to give you the
folder's title.

No.

I mean that setting a production flag on the zope server and let all error
messages goes silent.

It will be very difficult and troublesome to keep track of all errors. Just
because some one have make a rename on one of my object, or the object is
being modify and thus not available.

Also, are there anyway to remove all the manage things from a production
site?

Are you killing the server between restarts, or closing it politely
with the management interface? The polite shutdown writes an index
file that speeds up the restart.

My development database has 30k objects, and restarts in under 3
seconds.

The call Pavlos gave does not visibly expose the user to the
management interface.  It does assume that the variables to be
changed were supplied in a form that caused this method to be
called, but that can be your own tailored form.  Or if you get
the values some other way, you should be able to pass them as
args to the call.

there are a few of howtos in Zope which use structure text were broken. I
dont remember all of them, but the one with date and sql is (I still can not
read it).

BTW, I  think structure text should be not be used in current way.  I think
a good use of structure text is to use it convert from/to. Instead of
publish.

A greate tool but in bad use.

But what would that look like?  The task requested by the user can't
be completed, so they need to get *some* sort of error message.  Or is
it that you are running with -D and so getting the python tracebacks
in the error web pages and you want to eliminate those?  In that
case, just remove the -D from your start script.

No, but anonymous users can't (by default) access the management
screens.  If your visitors have userids, just don't give them
permission to access the management interface, and they'll never
see it.

If it's a DTML Method, you could do <dtml-var
"whatever.whateverelse.object(_.None, _)">

There is also a _.render method that I've never had occasion to use.

Also, if you want to make things a bit more generic and work somewhat like
the Redirector, you could also do a
<dtml-var "REQUEST.resolve_url(the_new_complete_url)(_.None, _)">

All untested, but will hopefully help you along...

Hi,

I have the following python Class in MyTest module:

import DocumentTemplate

class Test:
	index_html = DocumentTemplate.HTMLFile('test_form.dtml')
	
	def __init__(self):
		... 

	...

	def mymethod(self):
		return 'Hello'

In my DoTest.py module i have:
import MyTest
t=MyTest.Test()


If I run:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t

i get the correct output (a html file with http header).

but if I try:

python /usr/local/zope/lib/python/ZPublisher/Test.py DoTest t/mythod

i get the following error message:
***************************
Status: 404 Not Found

...

  <H2>Zope Error</H2>
  <P>Zope has encountered an error while publishing this resource.

<!--

I really don't know what is my mistake. I'm pretty sure that mymethod is a
method of the Test class. I can also access to the variable index_html of the
Test class, so why am I unable to access Test instance methods this way?

Actually, I also tried the example in the Zen HowTo: The (old) Product API
Tutorial. Is there now another way to call a python class instance method
with the debugger?

If I do the <image src=imagename explicitly I have to fill

Thanks for this. Only just got round to trying it. For dummies
like me does "re-build" means do "python wo_pcgi.py" again
from the root of your Zope install (under Linux)? (Having,
of course, replaced the lib/python/ZODB/TimeStamp.c file.)

I hope so because I just did it and it seems to have solved
the problem in as much as new News Items in my PTK-generated
pages no longer all have dates of 29 Feb. (I guess there may
be more finely honed ways of just causing a selective
re-build ....)


I note, however, that those News Items that were created with wrong 
dates, still have wrong dates (at least as displayed on 
the Web pages). Perhaps this is a problem that is just
local to the PTK?

Yeah, I knew that, but I love the fact that everything in python is really
just assignment, so I do it explicitly a lot.  I got carried away... :-)

Your method does not have a doc string.  ZPublisher will not call a
method unless it has a doc string.

The FTP handler does not accept a hostname argument in it's
constructor.  This is probably an artifact of the medusa code. 
Shouldn't be a hard fix.

The monitor server is hardwired to localhost.  I believe this was a
security decision.  You can hack z2.py any way you like to remedy it.

Nope.  Zope does not speak SSI.  It speaks a very similarly looking
language called DTML.  DTMLs 'old' syntax _looks_ like SSI, but it is
not.  It is syntactically different in many cases, and does not support
neccesarily same kinds of tags.

I sugest you read the Document Template Markup Language Users Guide on
the zope site.  It's in the Documentation section.

Subject: [Zope] condional client-side code
Message-ID: <38CD3812.64591827@open.ac.uk>

Ideas please - how to do this.

I'm using zope in frames and need some output to be
condionally there depending on what the window name
is.  The idea is  for client-side code to decide 
whether or not its displaying in a frame and output
a header if needed.

The only way I know to do this is with javascript

"if (window.name=="whatever")" etc.
on the client side.  What makes is messy
is having to hand-process the stuff that's on the
"then" part to put it in document.write() calls.

This is quite messy because there's quotes and all sorts in
it.  It would be nice to write

    document.write("<dtml-var whatever>")

but because of messy chars and returns and so in
in the "whatever" document it doesn't work.  Also,
its really desirable to be able to have "whatever"
in just one place and use it in different ways in
different documents.

My current thinking is - "is there some way I could
process the contents on "whatever" on the fly so that
it would work with document.write?

Any other ways to do what I want?

I believe error code 11 is a segfault, pointing toward a memory
problem.  I just finished dealing with a situation where zserver
was restarting, and increasing the available memory for the
process circumvented the problem.  This may well not be your
problem, but it may be worth looking at.

Is Zope supposed to handle out-of-memory problems gracefully?

For images, you can use:

<dtml-var "imagename.tag(border='0')">

I'm not sure what a "general method" would apply to, but I'd hazard
to guess that any object that produces a tag when rendered should
probably have a similar tag method...

Does Zope leave a core file?  Try 'find -name core -print' from the top
level directory.

Subject: [Zope] Enhydra anyone?
Message-ID: <20000313201057.94590.qmail@hotmail.com>

Hi,

Is there any comparison between Enhydra (Java-based open-source
application server) and Zope (Python-base open-source application
server)?

I guess Zope and Enhydra are colliding head-on. :) Can anyone
give a little bit more background to Enhydra?

Zope site used to have a page about comparisons (like with
PHP), now I cannot find that page.

Having worked with Java (and previously with C++), I must say
that I don't have a positive opinion about Java. I know Enhydra
has this "open source" thingy and even tries its best at painting
"worldwide developer hall of fame" stuff, but it seems kind of
corny. I just don't think you can do open source well enough
with a language like Java which was designed by the corportate
and for the corporate.

It's not that Zope is excellent, it's not. But Python's CP4E
(computer programming for everyone) approach eventually will
make it longer lasting than anything else, (especially after
Python 2 comes out) and I just don't see how Java can
survive in the long run. As for Zope, I guess in the long
run it will need a major re-work, otherwise it will lost
the competitive edge.

Message-ID: <001b01bf8d2b$aaf24ee0$0201a8c0@iridium>

Here is my quick intro to Enydra and why I think it is interesting.

Enhydra (http://enhydra.org)
======

Licence : OpenSource.
Technologies : Java Servlets, XML DOM.

Java-based Enhydra has possibly the most interesting take. It uses
JavaServlets to provide content. You give it your HTML file, marked up with
some extra attribute tags :

<HEAD>
</HEAD>
<BODY>
  <P ID=Fred></P>  <!-- a Param tag with ID -->
  <P ID=Jim></P>     <!-- another -->
</BODY>

It then turns this HTML into a Java class with all the tagged elements given
getter/setter methods in the class. It compiles the class.

So now if I want to do something with the HTML fragment above I just create
an instance of MyClass and do things like :

  GetElementJim.SetText('My content for Para1');
  GetElementFred.SetText('My content for Para2');

In essence the Class models a XML DOM tree for the HTML put in so you can
now apply DOM methods to it to manipulate the model.

This neat because :

1. It's in compiled (well, as far as Java compiles) code so is quick.
2. DOMs  kick out "compressed" XML content, all redundant spaces CR/LF pairs
are removed.

Enyhdra also pools DB connections to improve performance.

Message-ID: <38cd5575.3a09.0@jps.net>

Hi Dave,

Unfortunately, I don't have an answer yet.  I am still trying to get the damn
thing to work.  I had ZMySQLDA working until I tried to run a query.  Then I
got the same error that I got when using MySQLdb.

Right now I am in the process of wiping everythin out (short of Linux itself)
and will try a re-install.  I hate doing this because I still don't understand
the source of the problem!

Anyway, I'll keep you updated...

Seems like this discussion should be moved to c.l.p., but ...

I don't understand your objection here. Tuples are immutable "by
design," or "by definition" if you prefer.

What alternative approach would you suggest?

We certainly benefit from having a mutable sequence type designed to
contain arbitrary objects.

We benefit from having a high level mapping type designed into the
language. You agree that dictionary keys must be immutable and you
appear to agree that sequences make useful keys, as well.

Under the covers, we also benefit from Python's design choice that
assignments create object references and the design choice that
dictionaries hash object references, not the objects themselves (which
therefore requires immutable keys).

So what's wrong with Guido setting things up this way and then saying,
"hmmm, this is pretty cool, we just need an immutable sequence type for
use in dictionary keys."

It's a little like the Old Testament Creation mythology. God creates the
heavens and the earth and he sees that it is good. But he decides he
needs to populate it. He finds that one human type isn't enough -- it
gets lonely. So it turns out that in His world, he needs two essentially
similar types, but with a key difference.

So Guido took a rib from the list and made the tuple.  ;)

For my own information, could you tell me how big big is?  I'm running a
database of 60K objects, and when there is a lot of activity on the 
database, the process grows to about 150M.  At around 180M, it
locked up and I had to restart Zope.  I think my server ran out of
available virtual memory.  (I'm moving the database to a dedicated
server Real Soon Now).

I use the attached script to batch-upload directories of jpegs as Photo

I found the source to String.__call__ (in DocumentTemplate/DT_String.py) very
enlightening. This is the same __call__ method that DTMLMethod and DTMLDocument
inherit.


    def __call__(self,client=None,mapping={},**kw):
        '''\
        Generate a document from a document template.

        The document will be generated by inserting values into the
        format string specified when the document template was
        created.  Values are inserted using standard python named
        string formats.

        The optional argument 'client' is used to specify a object
        containing values to be looked up.  Values will be looked up
        using getattr, so inheritence of values is supported.  Note
        that names beginning with '_' will not be looked up from the
        client.

        The optional argument, 'mapping' is used to specify a mapping
        object containing values to be inserted.

        Values to be inserted may also be specified using keyword
        arguments.

        Values will be inserted from one of several sources.  The
        sources, in the order in which they are consulted, are:

          o  Keyword arguments,

          o  The 'client' argument,

          o  The 'mapping' argument,

          o  The keyword arguments provided when the object was
             created, and

          o  The 'mapping' argument provided when the template was
             created.

        '''

You can see that __call__ with no arguments uses defaults of None and {} for
client and mapping, so essentially the template has nowhere to look up
attributes. This is why you must pass these explicitly. Apparently you can also
pass a mapping and keywords to the constructor but I don't think this is
possible from the management interface.

More ZZen is to be found in DocumentTemplate/DT_Util.py. This module contains
the expression evaluation machinery, as well as the code to the special
namespace variable, '_'.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A069@express.sematech.org>

I've put the following in a SQL method, but can't figure out where the count
ends up...

<dtml-in "_.string.split(tool_id)">

tool_id is a string (like 'EXP01 EXP02 EXP03').  For my normal DB activities I
use count-attribute name for the count total, but I can't seem to find out where
the count is stored in this example...  I tried getting the key with
sequence-key, which returned 1, but count-1 returns 0.

I've solved this already with
<dtml-if expr="_.len(_.string.split(tool_id)) > 1">

but this bothers me....  I know theres a better way!

Hmm, a simple test script seems to indicate that sending a child process
a signal 11 does not cause it to dump core.  Of course, it also does not
seem to cause it to return a status code of 11 either.  This might not
be a SIGSEGV, it might just be a coincidence that the return code of the
(crashed) child is 11.  (FYI, there are two processing going on here, a
'watcher' parent and a child, the parent prints the 'Aieee!' when the
child dies.

Does anyone out there know what a python program returning 11 means?

I think both NS and IE default to check for modified content 'only once per

I know that Zope has the capabality to keep up some sort of version
managament system for zope documents.  I have two questions concerning
this.  One, where might I find some more info concerning this.  And two,
what if I want to use my fav editor - say vi or pico...but that's another
war I don't want to start ;)...instead of the window that zope provides.
IF the file already exists in zope, and then I go and make changes in a
separate editor, and upload the file, since I am uploading the file, will
zope keep track of this as just another version of the same file?  Thanks.

I don't know where the docs are, but I just started using versions
so I can answer this.

In your top level folder, go to the 'add' box and select 'version'
from the items to add.  This will create an object in that folder.
click on the object, and you'll get some management tabs.  You can
'join the version', and you can save or discard changes.  Once you
have joined the version any changes you make will not be visible
to anyone who has not also joined the version.  (Making changes
to an object will lock out any other updates to that object from anyone
not in the version).  When you are satisified that your changes
are working, you 'save' the version, which makes them visible to
the rest of the world. 

Each change you make to an object is committed to the zodb in a 
transaction, by the way, so even without versions you can
go back and "undo" a change you have made using the undo management
tab.  I'm not quite sure about the rules that determine when
a transaction is burried deeply enough in the undo stack that you
have to undo things above it to get to it, but it is still a
very handy feature.

Someone is developing a ZopeEdit program that helps with this.  I haven't
looked at it yet.

Yes, the upload should appear in the undo stack.

Message-ID: <00031317565600.03374@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi,

I'm trying to make my own pyhton classes and use them with zope, so I tried to
subclass the class Persistent. However, no matter what I try I get always an
error like:
***
Bobo-Exception-Value:
(<class exceptions.ImportError at 80a9d98>, 
'cannot import name Persistent')
***

I have read "The (old) Product API Tutorial", "Create a Boring Product in
Python" and "ZODB" HowTos but I didn't find the exact way to do it. Even
reading the Persistence module doesn't enlighten me too much: it's just the
license and a string.

So I would appreciate if someone could give a clue about how to subclass
Persistent and to which module it belong?

Oscar

If you're trying to import your product into the interpreter, you have to load
the Zope framework first. The Zope initialization is where the Persistent module
is populated.

From $zopedir/lib/python:

import Zope
import Products.MyProduct
etc...

Access Rules are triggered before authentication can be performed, so their
permissions are nil.  If you want them to access anything other than REQUEST
(as you do) you must give them a Proxy role.

A lot of this is actually a question of terminology.  It is true that
Zope keeps previous revisions of objects around.  This is how you can
'undo' them.  However, this is somewhat unrelated to a Zope 'Version'. 
In the case of multiple revisions of an object, we call them revisions,
not versions.

A 'Version' is an object that you can join or leave.  When you join it,
you are given a 'private view' of your entire managment session.  Any
changes you make will not be shown on the 'public view'.  You can leave
a version and rejoin it.  You can commit a version or discard it.  That
pretty much sums it up.

You do not need to use Versions to get the benefit of previous revisions
and undo, Zope does this for you out of the box.

Your question about editors is related to all this.  You can
edit/add/delete object through HTTP using the managment interface, you
can also use HTTP POST and GET methods directly, WebDAV, or XML-RPC. 
All of these methods are based on HTTP (some editors work directly with
HTTP, or use a protocol transported over HTTP like WebDAV).  You can
also use FTP.  Any changes you make with any of these protocols will
cause a new revision of an object to be written, meaning that they can
all be 'undone'.

FTP however does not work with Zope 'Versions'.  You cannot use FTP to
upload information in a Version that you have joined because FTP has no
join/leave/commit/discard semantics.

Message-ID: <38CD82B7.66FDB982@exceptionalminds.com>

Hi,

I've been playing with WorldPilot on my little notebook PC running
RH6.1, and have noticed that when I access my WorldPilot folder, my
processor spikes and stays spiked until I kill my ZServer and restart.

My machine is just only a 233 w/64Mb RAM, but I have never seen Zope
behave this way with any other products. Running a top shows that my
python/ZServer processes are consuming far  more than their fair share
of cycles.

Has anyone else noticed this?

Thanks.

zopistas,

how would I write a dtml_method to render a objects history (undoable
transactions/revisions)?  any insight is much appreciated.  how about being
able to export the objects history (revisions) via XML and then I could pack
and then reimport it into ZODB (or is this complete madness? ) - this way I
can still pack and keep revisions around of specific objects... 

i.e. I would like to keep all objects revisions but need to PACK the DB
(because its overwhelming large) -- what is the way, masters de zope?

many thanks,

Message-ID: <38CD88EC.36D70F86@ep.newtimes.com>

After looking at both Zope and Enhydra I concluded for my purposes that
they really fit into two very different realms.  Both tools
(applications, application interfaces, whatever you want to call them)
fit the bill for developing web applications.  Both tools provide for
HTML/XML markup to easily integrate with web designers. 

Enhydra deviates from here to be more consultant/development driven with
its class file delivery/deployment method.  Where as Zope continues, it
provides an interactive management model, where the web designer can
update an application and extent it without having to have development
support, there is no compile phase that needs to be done before
deployment.

I believe it depends on what your perspective; If you're more
development centric, Enhydra works great.  If you have to interface
developers and designers on a an ongoing basis and want to deligate more
control to designers Zope is the winner.

Well thats my 2 cents.

Message-ID: <m3ya7ms7uo.fsf@wacko.pdx.net>

I've been reading through code trying to figure out what is going on
here, where this message might be coming from.  My current train of
thought is that the 11 exit code being seen is in z2.py is a result of
sys.ZServerExitCode getting set somewhere and z2.py exiting with that
code.

So I've been trying to find where code sets sys.ZServerExitCode and
what I've found is in ZServer.HTTPResponse.ChannelPipe.close.  In this
routine, the value of self._shutdown is assigned to r which then gets
assigned to sys.ZServerExitCode.  

It looks like self._shutdown only gets assigned when
ZServer.HTTPResponse.ChannelPipe.finish gets called and a response
header contains an bobo-exception-type of exceptions.SystemExit.

So I'm guessing now that somewhere this exception is getting set but I
can't seem to figure out why.

Am I completely off base here?

Subject: [Zope] Problems with dtml-in batch variables.
Message-ID: <00031412082101.01516@localhost.localdomain>

Greetings,

I am using the ever-so-handy next-sequence-* and previous-sequence-* variables
for a batched list.  This all seems to work fine, allowing users to look
through bite-sized portions of the list.

However, there seems to be a problem.  Whatever calculates these values appears
to assume that the numbers are sequential, which, in my case, they are not.

So, whilst i get the correct number of items each time, they overlap when they
shouldn't, and the next/previous limits are reported incorrectly.

The dtml-in tag in question is :

    <dtml-in "sqlQueryHere()" size=4 start=qs orphan=0>

Any comments?

Chris,

Are you saying that realmedia and netperceptions do their stuff
using Zope?  I've scanned their pages and can't find evidence
of that.  Or are you saying to go with a non-zope approach?
Seems like the non-zope way might be more expensive, for
a small site.

Hi,

Could anyone point me to any code snippets, which allows a user to add a
file attachment to a sendmail form.

I tryed the code in the user documentation, and the attachment is a .dat
file which contains the path name to the attached file?!?

I don't *think* there is canned solution to this in Zope, though
I haven't looked at any of the banner products yet.  But in
principle it is simple enough: the page that is responding to
the search query has access to all the search variables, so it
can decide which banner to include based on those keywords.  For
a simple banner list, dtml-if logic would be sufficient.  But
you probably really want it integrated with a complete banner
product.

In about two months I'm going to have to implement this for a
client.  I'm expecting to add it to one of the banner products
if they don't support it already by then <grin>.

I'm not sure what Chris meant, but it seems like you could do what Marc
wants pretty simply using ZCatalog. Just set up a catalog that indexes the
ads by keyword or title that matches the desired search. Then, when
presenting the search results, pick an appropriate ad from the Catalog...

No.  We just don't have a banner ad product that does targeting.

RealMedia does a very good job of targeting.  It's not (terribly) cheap,
but it does have lots of features.

NetPerceptions can help if you spend lots of time and $.  It's not a
banner ad system in itself, but a collaborative filtering engine that
you can produce recommendations with.  This can help in ad targeting. 
It's incredibly expensive.

And yes, I would say to go with a non-Zope approach right now unless
you're willing to put in the time to write an ad targeting and delivery
system yourself.  We'd love to see such a beast, but done properly its a
fairly complex and time-consuming undertaking.  We've chosen to
recommend off the shelf systems for a couple customers rather than
building our own so far.

Is there anyone else who has been having Zope crashes where SQL in related.  We

Subject: [Zope] User Role, Authentication, HTTP
Message-ID: <20000314035606.71539.qmail@hotmail.com>

Hi,

I have the following situation:

(1) I'd like to use Zope's security model, so I can prevent
    unauthorized users from accessing contents in subfolders.

(2) I want to keep user name and password in a database,
    not in acl_users folder. (Basically, I would like
    ZODB to be read-only. So I can't add users into acl_users,
    I have to add users into my own database.)

(3) I don't want to use the pop-up dialog box to enter the
    user name and password. I want to do it through HTTP
    form interface.

So, what can I do?

Is there a way in Python to tap into ZODB Authentication?
I mean, I could create a generic user for the purpose of
ZODB user authentication, and then activate the ZODB generic
user from the HTML authentication. Or is there a way to
add a role to the current AUTHENTICATED_USER, dynamically?
This problem seems common enough that people have probably
addressed it before.

Where can I find more information on manipulating Zope's
AUTHENTICATED_USER?

regards,

Hung Jung

Message-ID: <3.0.6.32.20000313212413.008ef100@pop.dnvr.uswest.net>

I have a few questions as to how to map zope objcts in python, and I'm
looking for help with this particular example.



I am trying to create a python method that will take one argument, a string
variable.  It will then find the people that match and return a list with
each of the person's data.



I have found two methods that come close to doing what I am after.  The
first one returns all of the people data, including all the variables, and
the second one filters out the people I don't want, but only returns the
ids.  I've tried switching aroung the map(None,self.ids) to
map(None,self.data) and I get typerrors from lambda.  

I don't fully understand how this is working or what the data looks like to
the interpreter, but I know I'm close

Can anyone help?



I've got ! these both work ! :

--------

    def peopleValues(self):
        """ return list of people's data  """
        return map(lambda x, p=self: x.__of__(p), self.data.map(self.ids))


    def remote_personlist(self, thisdjname):
        """ returns true with ids to remote people that match
        """
        rlist = map(None,self.ids)
        rlist = filter(lambda x,p=self : p.data[x].meta_type == 'This Kind
of Person', rlist)
        rlist = filter(lambda x,p=self,s=thispersonname :
p.data[x].clientpersonname == s, rlist)
        return rlist

You're absolutely correct.  It doesn't appear to be in the documentation.  The
closest I could find was an offhand reference to 'sequence-length' in the ZQR. 
I just assumed that since 'previous-sequence-size' and 'next-sequence-size'
existed, sequence-size would also.

Did it, in fact, work?

Hmm... have you looked at the Generic User Folder Product?

I think it would solve your purpose. There is also a howto for

I don't think zope should crash if this happens -- but is there any time
when you'd be retrieving data that it wouldn't crash (insert name of your
favorite web browser here, it doesn't matter which one)?

Subject: [Zope] DTMLTemplate product 0.2.0 released
Message-ID: <200003140538.AAA03457@ml.media.mit.edu>

I've just released my first development version of DTMLTemplates.

You can find the distribution at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate

DTML Templates are documents that allow blocks of text to be named and
made available to other documents. The basic building block of
templates is the DTML "block" tag, which can also be used with other
DTML document types. Templates export their blocks. Another new tag,
the "suppress" tag, allows block definition without rendering.

Here are several nice features of blocks and templates that I believe
will greatly benefit the Zope community (several of these items have
come up recently in Zope email discussions):

	* defines libraries of methods in one file,

	* allows structured text formatting in a DTML document,

	* allows pieces of multiple documents to be combined,

	* allows complex web designs created with HTML editors 
          to be used as templates,

	* provides template elements that encourage proper
	  nesting of markup tags.

In short, I think that Templates offer great promise for the Zope
and Zope developers.

This release is a very early one, though.  A construct as fundamental
as this one may need both syntactic and structural tweaks to function
in the most useful way, and only with discussion can we figure that
way out.  Please don't count on this product being stable for at least
a couple of releases.  

I appreciate your interest and feedback.

This is a Zope crash, not a browser.  Zope dies with a NT exception.

I am currently adding this to my BannerClass foundation. I expect to
have this out in the next month or so. As to how well it will work, that
is up in the air at the moment.

<dtml-alert type=semi-vaporware>
"ZBanner System" (or whatever the final name will be) currently is
capable of hit/click tracking, verification of banner validity based
upon time (after, until, or during a date range), a set variable by
management, hitcount, and clickcount (I think that's all of them). It
also has preference capability (ad weighting).

It also supports ad style and type (where style is button, vertical
banner, and horizontal banner; and type is 'integrated', 'remote',
'local').  In the near future it will be able to call ads based upon
keywords passed to it.

So, why is this not yet fully available you ask? The feature I haven't
mentioned yet. Database independance. Basically, I want to get it set up
to where you can store your banners in the ZODB, and RDBMS, localfs,
whatever. So far, I have a good foundation, but need to pin down the API
better. WHen it comes out, I want to include an example implementation
or two. As soon as my test ZServer works properly again, I'll be able to
progress faster.

Wow, wow wow. :) Thank you very much. I'll try it out!
Seems exactly what I want.

It's funny, I have seen quite a few postings mentioning
about GUF and Generic User Folder before, (never understood
what it was, though,) and I even mentioned in my own message
that I wanted to create a "Generic User." But somehow I just
never made the connection. :)

Subject: [Zope] XXX-PythonMethods caveats?
Message-ID: <v04220800b4f3a7c28944@[128.240.198.13]>

Hi all,
I'm using Evan Simpsons' XXX-PythonMethods with great results (after 
a few false starts due to my ignorance!). However, in Guarded.py we 
have the following;

# BEWARE OF THE LEOPARD!

# Set 'do_XXX' true to allow creation of XXXPythonMethods
# and ADD A MASSIVE GAPING SECURITY HOLE to Zope.
# DON'T DO THIS unless you use secure connections for ALL OF
# YOUR ADMINISTRATION or are RECKLESS and/or FEARLESS.
# Even if you DON'T create ANY XXXPythonMethods, just turning this
# on will PUT YOU AT RISK BIGTIME!

Of course, I then set
do_XXX=1   :)

I only ever run my Zope servers under a non-priviledged account.

Can anyone explain what sort of leopards I should look out for, as I 
can see that I'd want to use XXX-PythonMethods for a lot more things.

Tone
ps the icon for the XXX-PythonMethod object is way cool! :)

Subject: [Zope] httpd.conf HELP! please
Message-ID: <Pine.LNX.4.10.10003140058240.20645-100000@hal.rescomp.berkeley.edu>

Good evening. We are a student group here at University of California,
Berkeley, and for the past couple of months we have been trying
(unsuccessfully) to get Zope to work with Apache properly. (We are
Residential Computing, a group which provides connectivity and support to
the residence halls at the UC Berkeley.)

The situation is as follows:

Right now, apache has been configured to pass all requests to zope.cgi
except for our personal pages (/about/staff), which a rewrite rule is
directing to a static file system location.

Our problem lies in an internal section of our site. We call it
/internal/.

What we are having problems with is getting Apache to authenticate the
user BEFORE it redirects to /internal/ in Zope. The other snag: everything
under /internal/ is under SSL. One area where we are not certain is if the
require user authentication specs should be in LOCATION tags or DIRECTORY
tags.

In addition to advice, if you have a similar set-up we would really
appreciate a snap-shot of your httpd.conf.

I have included snippits of out httpd.conf file below.

Thanks for your help,
Sachin

I'm seeing that on a box running BSDI.  I haven't looked closely
enough to see what time it is logging, but it certainly doesn't
*claim* to be GMT (it's giving -4 for the offset, which is wrong
and does not relate in any way to either the real GMT offset (-5)

I would like to open discussion on Version access over FTP. Few weeks
ago I have posted some suggestion on this to Jim Fulton, but no
reaction. I know he is very busy and so maybe here I get any
response. Below, plaese see copy of what I have posted to Jim.

Hi Jim,
I have a problem with versions with FTP. I already read your comment in
mail-list and also made little of traffic on the Zope and Zope-dev
mail-lists. After this, maybe I have a suggestion how to solve the
versioning also over FTP and not only HTTP. This problem arised for me,
when I tried to work with versions edditing my DTML code in Emacs.
        I suggest to be version object a container object. The access to
the version over FTP could be determined in URL. (The ID of version
object, to which I want to make changes, must be a part of
URL. Additioanaly, commands for join/leave, commit .. should be also in
URL, just after the ID version.) This mechanism could allow to work with
versions also over FTP. The classical version management over web
interface in collaboratin with cookies will not be changed, the
mechanism to work with versions also over FTP will be an addition. In
addition, in this way, the other people could see the version
('functionality of version') also over HTTP if they know the version ID
and put it in the URL.
        What do you think about this? If there is any other possibility
to solve my problem, could you inform me? 

Thanks in advance,



Could anybody response to this, please.

Evan,

Cheers, gave an anonymous proxy role, worked a treat :-)

I did notice while playing around with this that moving or copying DTML methods that have been set
as site access rules did have some bizarre effects I wasn't expecting. I think when I copied one, it
stopped working, or something like that...as well as some other such wierdities, is this to be
expected?

Chris

PS: What do you, or anyone else for that matter, think of the rule as a solution to the problem in
my earlier post? I don't *think* I need any magic folders or anything else, but I'd like to get a
second (third, fourth and possibly fifth ;-) opinion before I put it into production...

<dtml-if "_.has_key('virtual_host') and REQUEST.environ['HTTP_HOST']==virtual_host">
 <dtml-call "REQUEST.setURL(path='/')">

   I'd more interested in fixing fast reload problem. There were some
reports in the list, that after installing SiteAccess Zope sometimes hangs
for a few seconds when you press Reload (in browser) a few times. I can
confirm this behaviour, but I've never realized the problem is in
SiteAccess - I never ran Zope without SiteAccess :)

Hello,


there used to be a way to change the base classes for a ZClass. It's 
documented here:

<http://lists.zope.org/pipermail/zope-dev/1999-August/001288.html>

I haven't used it recently. It worked for me several time in Zope 2.1.1.

Make sure you backup your database before trying it.

Salut Olivier,


Did you solve your issue below? If not, please reexplain what you are 
trying to achieve.

If you want to render one of your ZClass with <dtml-var myClass> you may 
need to subclass "Renderable BaseClass" (available on the Zope site).

Or I am barking up the wrong tree?

It would appear that a Site Root and a Site Access Rule containing the following are NOT the same:
<dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

as my site access rule didn't work :( (it left the URL, BASEx and absolute_url() unchanged)

The only way I could solve it was to do the following:

Site Access Rule:
<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

And then put an empty SiteRoot object in the folder of each virtually hosted site.

Why did I need to do this? (more out of curiosity than anything else...)
Also why do the SiteRoot objects have to be in the folder of the virtually hosted site? why can't I
just have one in the root folder which gets picked up through aquisition (they're all blank anyway
;-)

And, most importantly of all, why does adding a site access rule prevent FTP access to Zope?

Subject: [Zope] SiteAccess breaks FTP!
Message-ID: <38CE382B.E4088A9E@nipltd.com>

Hi,

I'm trying to sort out the relative URLs of some virtually hosted Zope sites.
In a nutshell, there some sites visible to the outside world as www.site1.com, www.site2.com, etc
These are in /site1, /site2, etc folders off Zope's root.
The redirection is done using Apache's Proxy method, but I need to sort out BASE, URL, and
absolute_url() type things, which I'm doing using the following Site Access Rule:

<dtml-in virtual_hosts>
<dtml-if "REQUEST.environ['HTTP_HOST']==_['sequence-item']">
 <dtml-call "REQUEST.set('SiteRootPATH','/')">
</dtml-if>
</dtml-in>

and blank SiteRoot objects in /site1, /site2, etc.

The only problem is that since I did this, I get the following whenever I try to FTP into Zope
(which used to work fine and which we use quite heavily for content editing with Dreamweaver):

 550 Could not list directory.

Why do I get this? How do I stop it happening? (preferably without stopping using SiteAccess...)

If anyone has any experience with this, I'd appreciate the help...

Chris

Mourning...

I've been trying to compile DCOracle for 8i under Linux and
I'm _really_ not cut out for messing about with C libraries.
I know Anthony Baxter has done it, but I have a strange feeling
he's probably not near a computer right now.

Has anyone else got this working?
If so could you send me your Setup file? (Better yet would be
to get it added to the ones already in the DCOracle package.)

Thanks for your time,

Chris,


I had exactly the same problem as you.

I eventually found it was a bad idea to use the precompiled python version
shipped with the binary package. In fact when I do :

$ python
>>> import _mysql

it works. However, when I do :

$ $ZOPEHOME/bin/python
>>> import _mysql

It doesn't.


So, I think the best thing to do is to bypass the binary python shipped with
the tarball. I'm dowloading the source version to check if it is ok.

I can't get this to work at all:
<dtml-if "sequence-size > 1">
zope complains about not being able to find 'sequence'.  I had solved this issue
before with a let tag <dtml-let size=sequence-size>, but it seems very wasteful
and adds a lot of syntax overhead to the code.  How can I access the sequence
variable in an expression?

Actually, I'm checking to see if I've got multiple elements.  If I do, then I
use IN () in my DB query, else I put in =.  When I split the string, I don't
know if I have multiple items.

Access Rules are designated by name within their container; If you rename
them, copy them, or move them, the new/renamed method will not be a Rule
unless you designate it as one.

Looks good! This is similar to the solution that Digital Creations came up
with, and is better, I think, than my SiteRoot behavior.

> It would appear that a Site Root and a Site Access Rule containing the

> <dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)">

Was this Rule living in the subfolder where the SiteRoot would have been?

Location determines the point at which the SiteRoot affects the URLs.  If
they did their internal 'setURL' in the root, all that would allow is
replacing the initial '/' with the path of your choice, when what you want
is to replace '/foo' (or whatever) with '/'.  A variant of the SiteRoot
scheme in which you could say "replace /foo with /" in the root would
require either rewriting the URLn/BASEn and absolute_url code to include the
replacement, or a hook after traversal completes which allowed the
replacement to be done before rendering the final object.  Either would
work.

> And, most importantly of all, why does adding a site access rule prevent
FTP access to Zope?

This is news to me! Prevents how?  What are the symptoms, and does it matter
what the Rule does?

So you've confirmed this behavior, and it goes away if you remove
SiteAccess?  Does it matter whether you're using an Access Rule or SiteRoot,
or is having the package installed enough to cause the problem?

[Sorry, I pressed the wrong key with my last message ; so here it is :]
Thanx Alex !

I've been fighting a little with the URL, but I got it  :)

For thoose who would have difficulties (like I've had!) here is the source
(should be zc.py) :

#!/dev/null
#
# (c) 1999 M.T.G. Handelsges.m.b.H.
#
# This module is only an experimental Extension module to play around with
ZClass internals.
#

import string

def fetchzclass(REQUEST,prefix=""):
    rg=REQUEST.get
    PARENTS=rg("PARENTS")
    product=rg(prefix+"product")
    zclass=rg(prefix+"zclass")
    app=PARENTS[-1]
    prod=getattr(app.Control_Panel.Products,product)
    zc=getattr(prod,zclass)
    return zc

def strbases(zc):
    r=[]
    for i in zc._zbases:
 r.append(str(i))
    return string.join(r,"\n")

def show(self,REQUEST):
    "This shows the bases of zclass in product."
    zc=fetchzclass(REQUEST)
    return strbases(zc)

def copybases(self,REQUEST):
    "this copies the bases from class srczclass in srcproduct to dstzclass
in dstproduct."
    src_class=fetchzclass(REQUEST,"src")
    dst_class=fetchzclass(REQUEST,"dst")
    dst_class._setBasesHoldOnToYourButts(src_class._zbases[1:])
    rg=REQUEST.get
    get_transaction().note("Copied baseclasses from %s[%s] to %s[%s]." %
      (rg("srcproduct"),rg("srczclass"),rg("dstproduct"),rg("dstzclass")))
    return strbases(dst_class)

Here is the doc (still from Andreas Kostyrka andreas@mtg.co.at):

Well, install the attached zc.py in your Externals directory. Add
external methods zc_copybases and zc_show (mapped to zc.py/copybases
and zc.py/show) somewhere in your ZOPE. For demonstration I assume
it's in your root folder, and your zope server is called
http://myzope/.

Well, then use your browser to visit the following URLs (this does
more or less exactly what the above python magic does):

http://myzope/zc_show?zclass=YourZClass&product=YourProduct
http://myzope/zc_show?zclass=TempZClass&product=YourProduct

   This shows you the baseclasses of the two Z classes.

http://myzope/zc_copybases?
srczclass=TempZClass&srcproduct=YourProduct&
dstzclass=YourZClass&dstproduct=YourProduct

   (This should be a one line URL.)
   This does the voodoo magic above. And completly without shutting down
your ZOPE, and
   it does even comment the transaction nicely. (Interesting question if it
is undoable.)

And yes, the attached file is twice unsupported ;)
1.) The voodoo is not supported by Digital Creations, so it may change
    at any time.
2.) The external module is not supported by MTG, as its voodoo coefficient
    is to high.

but...this is not exactly what I want :

I have two (or more) rendering methods ...
Sometimes I call one or another, depending on the page I want to render it
in...

I wanted to write :
<dtml-var myClass.render_1>
or <dtml-var "myClass.render_1()">


but never works :(
The only thing I've found to be working is :
<dtml-with myClass>
  <dtml-var render_1>
</dtml-with>

pas glop...

So, it's okay to copy a Site Access Rule DTML method to another folder and then set as a Site Access
rule in that folder? I could have sworn when I tried it, the original stopped working too...
...but I was probbably wrong...

Nope... I was hoping just to have one Site Root Access rule that got aquired for each site. Is that
not possible? :S

Evan,

I don't think it matters what the rule does, it's just enough to have one set. It does, however,
matter where it is. I had to remove the site rule in the root folder so people could get on with
their work, but I left one in one of the virtually hosted sites.

FTP access now works fine except in the folder with the Access Rule in it. That said, that folder is
a Squishdot site and so I don't think it was accessible from FTP anyway...

Hope this information helps :-)

Hello,

I am new to Zope, so this might be a FAQ, but my seraches of the Zope

I am using a Z Class with Property Sheets to define the fields for each of

Since python interprets "sequence-size" to be sequence minus size, you need
to do a namespace lookup to get at the value.

<dtml-if "_['sequence-size'] > 1">

will do the trick.

Corel is more of a desktop version, so I'd say not, while Debian has a Zope
package so it's very easy to install and upgrade.  But I personally use
Redhat (and will install Debian 2.2 when it's released.  And OpenBSD when I
get my CD...).  Truth is that it doesn't matter.  Especially if all you're
running is Zope.  If you're running Oracle or some other commercial software
you'd want a commercial distrib such RedHat or SuSE.

Not really.  Just use whatever you're comfortable with.

Nice to know the trick, though.  Now I just need to find where the sequence-size
is stored as....

This is almost a religous subject but here's my two cents

it depends on your experience and what you want to do.

i've run Zope on Suse6.3, redhat6.1 and mandrake7.0
the differences between redhat and mandrake for a server are pretty
minimal, basically the pentium tuning in mandrakes rpms which are
meaningless in the context of installing zope and python. so for the
purpose of this discussion i'll call them both redhat. 

for automating startup of zope:
i personally found suse6.3 rc scripts to be alot easier to figure out
they have skeleton in /etc/rc.d/ which you copy alter and symlink into
the /etc/rc.d/"runlevel" directories you want to start and stop zope in.

try man init.d (in Suse)

for playing around with experimental stuff:
i would def. have to say go with redhat. if you want to play with stuff
like ZopeStudio(interface into Mozilla). Suse6.3 comes with a lot of
stuff in RPMs on CDs but requires a bit more experience to get stuff
installed from source and most sites don't offer suse RPMs which
generally aren't compatible with redhat RPMs. Suse itself doesn't offer
updates on most of its RPMs unless they're bugfixes for major programs.

 
for locking the box down:
i would go with Suse6.3. a good sys admin could lock either down. it
really depends on your experience from a sysadmin level. suse6.3 has a
pretty nice hardening script that passes SAINT with flying colors.
Bastille Linux is basically a redhat hardening script but i haven't
played with it at all and it tends to lag slightly behind the latest
version of redhat. 

for a minimal install:
i would go with Redhat.

my choice: Suse, but thats my personal bias cause i think its a better
distro. 

as for the other distros: the only other one i would consider seriously
is Debian, cause it has a very nice package management system through
which keeping your system updated is easy.

in summary: i really don't think it makes a difference, just go with
what you know.

This is untested but it should do the trick:)

<dtml-if "_.int(sequence-size) > 1">

as to why this doesn't work 

> <dtml-if "_['sequence-size'] > 1">
>Error, exceptions.KeyError: sequence-size 

i'm on shaky ground but here i think that your trying to lookup
sequence-size in the namespace variable but the batch process variables
aren't really defined in the global namespace.

This gives a key error as well.  To summarize what I'm trying to do:

<dtml-in "_.string.split(string_with_1_or_more_words)">
  <dtml-if "we_have_>_1_items">
   we have <dtml-var what_is_this_var?> items
  <dtml-else>
   we have only 1 item
  </dtml-if>

I can do the > 1 check with <dtml-if "_.len(_.string.split(string)) > 1">, but
it seems I should be able to get to a count-nnn var inside.  Since I'm not using
a SQL statement, I don't know what the variable is named.  sequence-size give a
name error wherever I use it (from the test screen of a SQL query).  <dtml-var
sequence-key> returns the fist digit of the word.

So, the question is, in the statement:

Howdy sports fans.  If the San Francisco traffic doesn't double cross
me, I'll be speaking at the Bay Area Linux User's Group meeting next
Tue, Mar 21.  The complication arises because I'm speaking down in San
Jose at SDWest from 5PM-6PM, then have to hurry back to hopefully make
the BALUG meeting.

Unfortunately I don't have a URL handy for time, location, etc., but
I'll try and post it when I'm back in the office.

The subject of the talk is, well, Zope, plus a Big Announcement.

I can't comment too much on your problem, your report, although
detailed, still did not show everything, for example, how is it failing?
Does Zope show public pages but never lets you authenticate?

One thing I noticed is that you want Apache to authenticate, then you
try and pass the Auth headers into Zope.  You can't have it both ways,
either Apache authenticates you (and you are quite crippled in this
sense, using the front end web server to do authentication is not
desireable at all, and limits what Zope can do to a great extend) or
Zope authenticates you.  Perhaps I am not completly understanding what
you want to do, but I think you might be tackling too many problems at
once and your conf file apears to be very complex.

First, take out all the Apache auth and SSL and all the other Rewrites
and complexity and just get Zope to work with Apache.  _Then_ add
something else, and get it to work, and so on.  Further, you may want to
consult the Apache docs and inspect the environment that Apache sets up
for PCGI along each step of this process; Apache, for instance, may not
set up all of the CGI 1.1 environment variables in a way that makes Zope
happy when you use SSL.  Or maybe Apache ixnays the Auth header after it
does Auth.  I couldn't tell you either way.

This could very well be a memory error.  It would be interesting to know
if the underlying libraries could handle a dataset this large, in this
case it would not be Zope but the libraries (I can think of no reason
why python couldn't handle a 40MB object, but I can immagine a poorly
written python extension not doing this right, the old ct_sybase module
is a perfect example).  You didn't specify what database you are using.

There is only one reason why I can think of, clicking on the Shutdown
button. 

A quick grep shows sys.exit being called in a few places however, most
specificly in xmllib and pyexpat.  None of these calls set a value of 11
though.

Are you using any XML?  XML-RPC calls?

> Am I completely off base here?

Perhaps, it's a good avenue to look down however.  What I suspect is
that something is happening (like a SIGSEGV) that is causing the OS to
send a signal to the process whose default action is to kill the
process, setting the error code to 11 for some as-yet mysterious reason
(11 has *got* to be the clue however, I refuse to believe that it is
arbitrary, note also that SIGSEGV is signal 11, coincidence?).  A good
exercise may be to run Zope in gdb and wait, when one of these events
happens use gdb to inspect what's going on.  I'm no gdb expert however,
but I was under the idea that it could tell you when signals arrive (or
perhaps stop the process on the arival of a signal...)

I wrote a test script that forked a parent and child just like Zope. 
When I sent the child a SIGSEGV it returned an error code of 332.  Maybe
my experiment is flawed.  

Have you enough time to look that deeply?

To be more specific, it blocks all other requests through that and other
level 2 DAs.  Non SQL related calls and level 3 DA calls will not get
blocked.

Yeah that kinda puts a damper on the whole site... but that's just
because every access is now an SQL related call.

This is not what ZODB sub-transactions do.  Even if you were using a
relational database that has a notion of sub-transactions (Oracle has
'nested transactions' for example) that would not stop the blocking (of
course if you were using Oracle you would be using a level 3 DA...).
ZODB sub-transactions allow changed objects to get flushed to a temp
filestorage so that you can accumulate more object changes then can fit
in virtual memory.  There is no mapping of sub-transaction semantics to
any of the DAs.  In fact, if I remember correctly using ZODB
sub-transactions with SQL methods is Not A Good Thing.  I don't remember
the exact details.

Solutions?  Execute a shorter query or upgrade to a concurrent DA.

Subject: [Zope] More Z SQL head bashing...
Message-ID: <38CE754B.3F7DA16E@nipltd.com>

Hi,

Well, further to my earlier SQL post, here's the code I'm trying to encapsulate, but it doesn't work
;-)
The problem is one of getting a unique, integer, id from MySQL to use as a primary key for an
INSERT. And no, an AUTO_INCREMENT column won't help here 'cos I need to know what the number is
before I do the insert (it generates a reference number, which is used as the primary key, and needs
to be given back to the person doing the submission...)

Anyway, here's the Z SQL Method Code which goes into a MySQL DB connection:

SELECT COUNT(*) as exist FROM sequences WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
<dtml-if "exist==0">
 INSERT INTO sequences SET sequence=<dtml-sqlvar name type=string>, n=0
</dtml-if>
<dtml-var sql_delimiter>
UPDATE sequences SET n=LAST_INSERT_ID(n+1) WHERE sequence=<dtml-sqlvar name type=string>
<dtml-var sql_delimiter>
SELECT LAST_INSERT_ID() as number

When I try to test the method, I get a NameError for exists, which I presume is coming from the
dtml-if. Any idea what I'm doing wrong or other ways of solving this problem?

cheers,

Chris

I had a similar problem I just puzzled through, though I'm pretty new and don't
know the right ways yet :-)

What I did was create another DSQl query (sql_newID) that queried for the new ID
(select max(ID+1) as newID from table) and another sql_exist( select count
*....)  then I used this result, but it had to be within a <dtml-in > tag...

<dtml-in sql_exist>
  <dtml-if "exist > 0">
    <dtml-in sql_newID>
     insert into table (ID, name) values (<dtml-var newID>, <dtml-sqlvar
name...>
    </dtml-in>
  </dtml-if>
</dtml-in>

This worked because I knew the sql_newID and sql_exist will only return a single
value, so the loop only iterates once.  I've never seen the  <dtml-var
sqldelimiter>, though, so I don't know what it does....

Maybe this will help.....

I'm pretty sure now that async_loop is not exiting in my child process
so I'm guessing it is some other type of abort.  I'll try the gdb
avenue.  I'm pretty handy with that, but I've never done much
debugging python or threaded apps so....

I also grepped around the code and looked over every 11, sys.exit and
SystemExit I could find.  This is a real pain.

It's from the ZSQL guide, it lets you put more than one SQL statement in a ZSQL method. 
What I don't understand is why the 'exist' variable stops existing... (maybe I should have called it
something else... ;-)

Time of day can certainly be done. Shouldn't be that difficult to test
by IP, domain and browser, thoigu I admit I hadn't thought of them.


Basically, when called, a banner tests's it's validity agfainst a set of
rules, and those banners that pass are put into a list. that list is
built using weight, and the weights could be modified at runtime based
upon things such as keywords or other tests.

I have a bunch of really bad Python code sitting around here that tries
to do same.  I can't even remember how it does it.

It's got no docs and isn't even a working Zope product.  I doubt it will
help much.  But I can send it to you if you'd like.

That should work fine.  The only weird detail here is that the *icon* of the
method probably won't update correctly unless/until you make it not a Rule
before copying/renaming/moving it.  That's because the icon change is a
kludge.

Access Rules are *NEVER* acquired.  If they were, you'd have to think about
what they might do in every single contained folder.

Subject: [Zope] getting object given path
Message-ID: <Pine.BSI.3.96.1000314132519.17585J-100000@twirl.bitdance.com>

I know I've seen reference to a function to get an object reference
given a URL path, but I can't seem to find it.  It doesn't help
that I've been up for more than 24 hours trying to get this code to
work.

I'm just trying to update a series of objects programatically.
I have a form working that submits the data for a Catalog
query to select the correct objects.  The dtml-in statement
is working fine as evidenced by just printing the meta_data
Id.  However...

If I do a <dtml-with getobject(data_record_id)>, the 'id' variable
has the value of the id of the folder above the one the Catalog is
in.  Doing a <dtml-var> on the getobject call shows me a
'folder instandce'.  None of the cataloged items are folders,
they are ZClass instances.  Earlier I ran through the whole catalog
using the dtml-with construct and a reindex_object call, and the
reindexing worked fine.  But now if I try to call 
propertysheets.info.manageChangeProperties() I get told that 'info'
does not exist, even though that is definately the name of the
propertysheet.

I'm desperate to get this working for the client.  getpath returns
the correct value, so I think if I can turn that path into an
object I can access the property sheets and get them updated.  But I
also want to know what is going wrong with my Catalog and/or
the getobject method thereof.  I'm not sure where to start looking....

I'm running under Site Access, and I'm guessing that is the source
of my problem, somehow.

Thanks for the reference to the DTML Guide...it has helped a lot.  I have
come across something that I couldn't seem to find an answer to.  I have
the following line in my original code that I uploaded from an

replace the echo statements here...

href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80/

I found this snippet of code for an echo and set, but my attempts at
modifying it to work for this have failed.

Hi,

I am starting to look into GUF, but the documentation is
not very well done: it's a bit cryptic and disorganized,
and makes too much assumptions on what the user knows.

Where can I find more help/examples regarding GUF?

The How-To in http://www.zope.org/Members/hippy/GUF_SQL_crypt
is not too good, either. Arrghh... give me some more
hints and I'll prepare another How-To, OK? :)

and it seems that there are quite a few disasters. Horrible
disasters. Sorry, but GUF seems a bit too inmature.

So, let me come back to the original question again, beside
straight GUF, is there any other way of tapping into Zope's
security model and using a generic user?

Hi Olivier,


This sounds like a namespace issue.

When using the Python quoted syntax I think you need to enclose the namespace:

Could you try this:

<dtml-var "myClass.render_1(_.None, _)">


Here are explainations straight from my Zope snippets:

Note you could also pass additional variables:

Subject: [Zope] What if you can use Zope on development server only?
Message-ID: <20000314203306.46566.qmail@hotmail.com>

     Has anyone used Zope in a scenario where you don't have control of the 
production server?  In other words, I'm in a non-profit organization that 
rents space from a web host.  That web host doesn't have Zope installed and 
has no plans to install it.  I *might* be able to put Zope on my own 
personal Linux server, which would really make that machine like a 
development server.  Does anyone have any experience utilizing Zope in a 
scenario where the development and production servers are separate and the 
production server doesn't have Zope on it?

     I'd like to use Zope because our web site has reached the point where I 
really can't manage it myself (Ok, it reached that point over a year ago, 
but I'm finally frustrated enough to do something about it :).  I'd really 
like to be able to give other people in my organization, especially many who 
aren't ultra web savvy tech-heads, the ability to author content so I'm no 
longer a bottleneck to the site expanding regularly.  Zope looks like the 
best open source option to do this with.  I also considered Cocoon 
(http://xml.apache.org/cocoon/), but I know and love Python and Zope looks 
like it's both more mature and more well-established for this type of 
application.

     I also want to add that I *am* considering changing our web hosting 
provider, but due to other organizational changes in the non-profit it will 
have to wait at least six months (it's lower on my priority list than 
finding a replacement for our office manager, for example :).  I guess I'm 
just curious if there's a way to use Zope in my current scenario, without 
having to change to a web hosting company that already has Zope installed.

     thanks for any help anyone can provide,
     Anthony

But fs/select.c(sys_select) (in the linux kernel) DOES return
ERESTARTNOHAND of do_select returns a negative value.  This is, of
course, not documented in the select man page...  come to think of it,
it looks like the linux kernel returns ERESTARTNOHAND instead of EINTER
because (quoting the source comments) "ERESTARTSYS [instead of EINTER]
breaks at lest the xview clock binary, so I'm trying ERESTARTNOHAND
which restart only when you want to" [block comments are mine].

Fishy.

Well, after more poking around and experimenting, I'm able to make an
strace look like what my crashing server does by following these
steps...

start Zope (z2.py)
wait till everybody starts
attach an strace to child z2
wait till strace output shows I'm in select
send child z2 a SEGV

strace output matches what I see in production
event.log matches what I see in production

Now that I've figured this out, I managed to get ulimit set up so that
I will get a core file the next time this happens.

Let's hang on till I see the core.

I'm also going to play with getting gdb to work nicely.  I'm not sure
why this is failing yet.

I originally tried running Zope at pair.com, where I didn't have root access
to the box. I *did* have the ability to run CGIs and telnet in, however. You
can get Zope running in such a scenario. And, if they're running Apache with
mod_rewrite, you can even make Zope serve up your site's root.

    One note though: many ISPs don't want you to run a long-lived process.
If that's their policy, then you'll run into trouble that way.

    As far as running separate development and production servers, I believe
you can get something going. I think someone made a Product that will mirror
your Zope database in separate files. You'll lose all of Zope's cool dynamic
ability, but you'll at least be able to take advantage of the content
management.

Subject: [Zope] Getting the path of an Object
Message-ID: <38CEB515.DB36129E@globalcrossing.com>

Hey all, hope this one is relatively easy...

Background:
1. I have a zope site with folders, subfolders (possible several levels
of subfolders) and objects in them.
2. I built a simple interface to allow a user (with the correct
permissions) to see the tree. 
3. In the UI, each item (folder, subfolder, object etc) has a check box.
Kinda like the Zope UI


The question:
A user checks an object (folder, subfolder, object etc), how do I get
the path to the object that is checked.

i.e.

FolderA
	SubFolderB
		SubFolderC
			index_html

Suppose the user checked index_html in subFolderC. 
How do I get the path (which would be
FolderA/SubFolderB/SubFolderC/index_html)

The test code I am using looks like this (it's in a DTML Method):

<dtml-var standard_html_header>
<FORM ACTION="WhichFilesToExport" METHOD="POST">
<dtml-tree branches=objectValues>
  <INPUT TYPE="CHECKBOX" NAME="ids:list" VALUE="<dtml-var PATH_INFO>" >
        <IMG SRC="<dtml-var SCRIPT_NAME>/<dtml-var icon>">
       <dtml-var id>
</dtml-tree>
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Submit" >
<dtml-var standard_html_footer>

Using PATH_INFO obviously wont work since it returns the PATH_INFO of
this method and not the PATH_INFO of the checked item.


Any thoughts????????????

Thanks,
DR

R. David,

I think you want 
<dtml-in "Catalog(mystuff=mystuff)">
<dtml-with "resolve_url(getpath(data_record_id_),REQUEST)">
<dtml-call "propertysheets.MyProperties.manage_changeProperties(
           blah=foo
           blahblah=bar
           )">
</dtml-with>
</dtml-in>

This will change the properties to whatever you want for the instances
found in the above Catalog search (mystuff=mystuff).

All my best,

     Kevin, thanks for the information!  I do have CGI and telnet ability 
with this host, but I'm surprised that's sufficient to run Zope with.  I 
thought Zope would require a tighter integration with the web server (e.g., 
a mod_zope or something that needs to be compiled in so that Zope can catch 
special Zope-intended requests), and that I'd need root to install it.

     Do I have a misunderstanding of how Zope relates to the web server?  Is 
simple CGI access really enough to install and run Zope?  I was basing my 
understanding on the architecture documentation at 
http://www.zope.org/ZopeArchitecture and 
http://classic.zope.org:8080/Information/Components.

>     One note though: many ISPs don't want you to run a long-lived process.

     Hmm... interesting.  I'll have to look into that; thanks for the heads 
up.

     Yep... that's the tradeoff I figured I would have to accept.  I was 
even thinking I'd have to possibly write my own mirroring script, but wanted 
to see if there was a better way first.  Do you remember anything else about 
that product which might help me do a web search for it better (e.g., it 
definitely used the word "mirror", used the word synchronize a lot, etc.).

     thanks,
     Anthony

Well, I can't give it python, that would defeat the purpose of the 
chrooted webspace.

It seems to me that Zope maynot lend itself to being frozen.

Has anyone out there frozen Zope and managed it to continue to work?

If you use PCGI, Zope will work in a standard CGI environment. PCGI
(Persistent CGI) keeps Zope itself around in memory so that it does not need
to be loaded with each hit. However, you do pay the "fork tax", because the
small PCGI program needs to run. I don't know a lot about fastcgi, but you
may even be able to do that without root and eliminate the fork tax.

OK.. Two points.

Firstly, my appology.  I mistakenly believed sequence-size existed, since it's
previous- and next- counterparts do.  However, sequence-length aparently does.
(there is a reference to it in the ZQR, and it's also in the source code.)


Secondly, your problem stems from the fact that sequence-length is not a valid
variable name in Python.  you must use

<dtml-if "_['sequence-size'] > 1">

Annoying, yes... but that's the way somebody chose to go.  I don't know why,
but it's there.  In fact, if anyone could give me a good reason why it is this
way, I would be most appreciative.

Message-ID: <20000315001632.8621.qmail@hotmail.com>

OK, I know some of you are out there watching. :)

Here is what I found out you can do to use Zope's folder
security features using your own user info database, your
own login interface, and without using GUF (Generic User
Folder). It's kind of simple, so don't expect too much. :)
Hey, but at least it does not lock you up and send you
into a panic attack. :)

(1) Have your own login interface, and use some session
    management product or cookies to keep track of whether
    the user has been authenticated by you.

(2) Create additional user-defined roles at the root of
    your Zope project. (Click on the 'Security' tab of
    the root folder, and scroll to the bottom.) E.g:
    'teacher', 'student', 'parent', etc.

(3) Create an acl_users folder at the root of your Zope
    project. Inside the acl_users folder, add new generic
    users. E.g: 'GenericTeacher', 'GenericStudent',
    'GenericParent'. Assign non-trivial passwords to them,
    of course.

(4) In your standard_html_header or equivalent, you then
    check against your cookies or session data. If the
    user is a teacher, then call:

    <dtml-call "REQUEST.set('AUTHENTICATED_USER',
                acl_users.getUser('GenericTeacher'))">

Voila! Now you can use Zope's security settings to prevent
people from accessing given folders.

Message-ID: <DBEPIFAAMMDGMCBPNKJCIELOCIAA.dell7000@thot.net>

I don't know if this is do-able, but here goes.  I'd like to do something
like the following:

<dtml-var main_header>
<dtml-var "external site">
<dtml-var main_footer>

I know, this defeats the purpose of Zope to some degree, but in this case
I'd like to include an external site instead of employing frames.  Let's
say, for example, that I'd like to showcase a resource located on another
namespace.

I've tried:

<dtml-var "REQUEST.resolve_url(my_external_url)(_.None, _)">

but I get a namespace error for obvious reasons.  I realize that the
header's <body> tags would conflict with the external resources' and hence,
I'm not banking on anything.  I also looked at Redirector and found it to be
great for redirection within the same namespace, but I'm unsure on its
ability to redirect to external resources (or namespaces).

My dilemma is that I am using Zope to design a site and require Zope's
numerous features, but I need to include a CGI-rendered page within Zope
header and footers without using frames.  Ultimately, I intend to re-write
the CGI as a Zope object, but at present I'm at a loss.

Thanks in advance,

Mike

Subject: [Zope] WorldPilot IMAP folder filenames
Message-ID: <E12V23Q-0005Py-00@under.eng.cp.net>

I don't know if there are any standards here, but I'm moving a TWIG
installation to WorldPilotand am running into some IMAP folder
naming problems.

We have TWIG configured to look in ~<user>/imap/xyz for an IMAP
folder called "xyz".  This (per memory) is consistent with how I
recall other IMAP clients working outside of our use of "imap"
instead of the cannonical "Mail" (historical reasons).  Now, I can
edit WorldPilot's MailListRoot to be "imap", but the problem then is
that WorldPilot then looks for folders in ~<user>/imap.xyz (ie the
file "imap.xyz" versus the file "xyz" in the "imap" directory).

I'd thought the defacto standard was to use a directory and then
files underneath that.  No?  Is there a reason for WorldPilot taking
this tack?  It makes the migration less elegant (we can't let people
switch back and forth)..

why do I need a concept of a sub-transaction. Is there just something that I
can call that will commit all changes up until a certain point and then
begin the new transaction? I realize this will break the transaction model
to some extent but if the method is long and each iteration is indepedent
this seems a reasonable thing to do.

To do the work using a shorter query would mean breaking the method up into
chunks and then having to call it multiple times which is pretty ugly.

Tell me how to get a concurrent DA on NT without breaking the bank and I'll
do it.
So far I have:

- MS SQL server - Apparently sybaseDA will work but havn't been able to
compile it on NT. You need certain files from sybase I believe.

- SQLAnywhere - same problem as above.

- Oracle - too expensive.

- MySQL - No transactions.

- PostgresSQL - Got the NT binaries but can't get it working. Also can't
compile the postgresDA.

- ODBC - Not level 3.

As far as I can tell the above represents all the options I have open to me.

It's not immature, just unforgiving :-) GUF lets get down to the bare
bones of an authentication system. Unfortunately this tends to mean you 
have to build it all up from scratch. 

Sometime RSN I'll finish a the one I'm working on that uses postgresql
and I'll bundle that up as a package for people to use, or use as an
example. Not for a few weeks yet, though.

Look in the download section of www.zope.org for one. The first
question, though - what do you intend to authenticate out of? A
database? LDAP?

Think of it this way: under normal circumstances if someone hostile got full
access to your Zope management interface, through a bug or password sniffing
perhaps, your Data.fs would be toast.  That's what backups are for, of
course.  Put XXXPythonMethods in the picture and your entire Zope
installation, any filesystem areas writable by the Zope-process user, and
any services accessible to that user are subject to abuse.  Some of this can
also be handled by backups, but subtle subversion over a period long enough
to render backups worthless is a much greater possibility.

You might end up as a CPU server for arbitrary Python programs.  You might
not.  LOOK OUT, IT'S BEHIND Y..<glurk>

They had to have *something* positive going for them :-)

Message-ID: <000e01bf8e30$2c24b200$0100a8c0@pinol1.sfba.home.com>

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in
general?

Maybe you should make it into a HOWTO. It is really useful.

G'Day.

I need sending mail with multiple file attachement...
But really cool product MIMETools is not ready fully.

Quotation from MIMETools Readme:
"Currently, the MIMETools product's only function is to provide the
<!--#mime--> DTML tag."

When expected implementing of <!--#boundary--> tag?

Thanks,

Perhaps not, but in my experience, Bete ZOPE products are much more stable than

In the site I am currently developing I send of e-mails with attaches.  From a
quick grep of the MIMETools files, you can see the boundary tag already exists.

Here is a quick example:

<dtml-sendmail smtphost="192.168.1.211" mailto="curtis@umd.com.au"
mailfrom="zope@umd.com.au" subject="Attach">
<dtml-mime type=text/plain encode=7bit>
Here is some text.
<dtml-boundary type=text/plain disposition=attachment encode=7bit
name="file.txt">
This is in the attached file.
</dtml-mime>
</dtml-sendmail>

Hello Zopistas out there!

I just stumbled about the threadsafety of different SQL-DAs. I'm 
coming from mod_perl + MySQL so it seemed a natural choice for me to 
also run Zope with MySQL in the background. I'm doing research (= low 
budget) in clinical psychology and have people fill in all kinds of 
questionnaires regularly which I have to store somewhere later. 
Looking at some past messages it seems to me that free and speedy 
MySQL is awfully bottlenecked by MySQLdb and financially-out-of-range 
Oracle rules. But how big is the difference? Does anybody know?

It also came to my mind that I might be missing an important feature 
of Zope: ZODB. For some reason (lack of marketing?) I just didn't 
realize that there is a database behind Zope that I could use to 
store my stuff. Last night I read some documentation but I have some 
questions left open:

Can I access ZODB via TCP/IP socket to retrieve data for statistical 
calculations?

What about performance?

REQUEST.resolve_url().  URL should be unurl-quoted.

getobject actually uses REQUEST.resolve_url and getpath, IIRC, so this may
not help.  But give it a try.

Hi Alex...
thx again !

so, half glop...

Strictly using what you gave me didn't work :(

But, after seeking a little, the following works :

<dtml-var "myClass.render_1(myClass,_)">

But I really don't like it ! Why doesn't Zope give "self" itself ? As normal
python methods do ?

Thanx all !

Normally I'd say try,

href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST['REQUEST_URI']">;weblint"
(the new Zope syntax is <dtml-XXX, but you can use <!--#var XXX--> if you want.

But that doesn't work as REQUEST_URI gives a KeyError.
This is weird because other REQUEST variables seem to work. Any deep 
voodoo Zopistas know why?

<dtml-in "REQUEST.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

Hint:
To see all the REQUEST variables tack on /REQUEST to any URL you have 
(only works with Zope < 2.1.4) or put this in a dtml document
<dtml-var REQUEST>

To just get the environment variables;
<dtml-in "REQUEST.environ.items()">
<dtml-var sequence-key> : <dtml-var sequence-item> <br>
</dtml-in>

So your code should work if you do this;
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 
/<dtml-var "REQUEST.environ['REQUEST_URI']">;weblint"

(If this seems long winded, it's because I'm writing this as I figure 
it out! :)

Hint: Remember that anything inside "..." is a Python expression and 
Python, *not* Zope syntax applies.

That should work fine.

<sigh>
Ok, I probably shouldn't use them then.
</sigh>

But (you knew there was going to be a but :). They are *so* useful.
E.g. I've got a XXXMethod that imports the following;
import os, sys, string, mimetypes, stat
import DocumentTemplate
from Acquisition import Implicit
from OFS.Image import File
from OFS.content_types import guess_content_type

setting do_XXX=0 gives me;

<!--
  Error type:  ImportError
  Error value: __import__ not found
  -->

Which is fair enough as the docs on the Zope site say import is 
controlled. Can you please be a bit more explicit and let me know 
*what* I can import? The Python code is a bit over my head...

<compromise>
Would you say that you could use a XXX PythonMethod to debug code 
that is going to become an External Method?
</compromise>

Thanks for the help Evan, it's much appreciated.

You might be able to do something with urllib.urlretrieve (in an 
external method) and feed that back into Zope

*vaguely tested*
def doit(self, your_url):
	import urllib
	fn, h = urllib.urlretrieve(your_url)
	if h:
		fp = open(fn, "rb")
		data = fp.read()
	return data

You'll get junk like <HTML> and </HTML> in it, but it's a start...

I could be talking out of a hole in the top of my head here, but here goes:

If you get Andy Dustmans' MySQLdb Module 
(http://www.zope.org/Members/adustman/MySQLdb). It's designed to be 
thread-safe. I've always taken that to mean that if a Zope request 
does a ZSQL query that uses this module, then if another ZSQL query 
comes along (in a different Zope thread) then it is *not* blocked 
until the first query is finished, but runs alongside the first query.

If I'm wrong on this I would *really* appreciate a correction here.

The Digital Creations people aren't overly keen on MySQL because it 
doesn't support transactions, which the Zope system uses extensively 
(I only use it for 'Undo'). For the sort of queries I have (many many 
SELECTs, few INSERTs, that isn't a major problem to me).

I'd reckon so. Look into XML-RPC as an example. Of course you can 
just construct URLs that obtain the data you need (eg have a folder 
with lots of properties of the form prop_n and get the values as 
http://server/path/to/folder/prop_125) and perhaps use something like 
urllib (Python library) to do some machinations at the client end).


>What about performance?

People seem to reckon ZODB is fast enough. I think it's Python 
limited (but again, I could be wrong here). That's possibly where the 
pystone benchmark comes in; check these out;

180MHz 603e (Linux) = 850 (my home Zope system)
300MHz UltraSparc (Solaris) = 2800 (our production machine! :(
266MHz G3 (MacOS) = 4600
500MHz PIII (SUSE Linux) = 5400
700MHz PIII (Win32) = 10150!! (this is really annoying, this box cost 
1100 quid - the same as the yearly maintenance on our Sun iron :(

I have no idea why those last two numbers are so disparate for the 
want of 200MHz. We'll be putting Linux onto the 700MHz box to see 
what happens there...

I struggled a little with this and I now have it working (in development 
anyway) using an SQL database (PostgreSQL) to hold details of users. It 
seems to me that if you need to store a 'profile' on your registered users 
then this is the way to go. You need to read the README that comes with the 
distribution and also read the SQL How-to you've listed below. This do not 
really explain how to use it once it is set up so I added a 'Tip' at
http://www.zope.org/Members/Lunus/lunus_01

I'm still learning but I haven't found any reason _not_ to use GUF yet.

if you mean  and <dtml-if "(OUTPUT == 'PROENG') and 'MATRIX'">

then it is equivalent to <dtml-if "OUTPUT='PROENG'">

if OTOH you mean  and <dtml-if "OUTPUT == ('PROENG' and 'MATRIX')">

it is same as <dtml-if "OUTPUT=='MATRIX'">


which one did you mean ?

If you are not planning of storing thousands of forms and have them
accessed by many users/per second then ZODB is really a good solution and
it is *easy* too use. For example (in the simplest case) you can design a
ZClass that contains all the required fields and a form for the clients to
fill. A method can instantiate the ZClass in a folder and add the
parameters provided by the customer and thats about it in terms of simple
storage. You can have a method that returns the data in some convenient
format as a text file which you can then input into your favorite stat
package. Or you can get fancier and build an xmlrpc method in your stat
package if it supports xmlrpc (ie if your stat package is a set of perl
programs) and get the data directly into your package, or get even fancier
and incorporate your statistical analysis routines inside your Zope
product, but I am getting carried away here :-) (and yes it is doable, it
has been done and if you decide to take this route I have some PCA
routines in python you might want)

zopistas,

during load testing i often see zope / zserver restart or exiting

i'm doing my load testing with apache benchmark, concurrency level
around 10.

"some_simple_oracle_select" being a simple zsql method.

the system is zope 2.1.4 on a suse linux 6.1 

we're going into production soon and we will have to support medium

Subject: [Zope] more on DTML Templates
Message-ID: <200003151443.JAA14787@ml.media.mit.edu>

Here is an update on DTML Templates, and a more in depth explanation
of how they work.

** Update ** 

I've updated the DTMLTemplate product to allow commenting out block
definitions and importing blocks using keyword arguments to the
blocks() method.  The new version is 0.3.0

Find DTMLTemplate at:

http://www.zope.org/Members/halazar/Products/DTMLTemplate


** More Information **

Yesterday, Jonothan Farr (jfarr@real.com) asked about the differences
between Templates and the var tag.  Here's a short summary.


The Template product consists of the "dtml-block" tag and the 
"DTML Template" document type.  In a normal document, the dtml-block
described below::

   <dtml-block myblock>
     Block contents      
   </dtml-block>                   
                                 
works exactly like the following dtml::
                              
   <dtml-if myblock>
     <dtml-var myblock>
   <dtml-else>
     Block contents
   </dtml-if>

In addition, blocks can be used to insert structured text directly into
a DTML document (see the documentation for details)::

   <dtml-block mytext fmt="structured-text">
    * this is

    * structured text!
   </dtml-block>



DTML Templates use blocks in an additional way: to define DTML Methods
that other objects can use.  If the Template 'templ' contains the
following lines::

   <dtml-block myblock>
    Block contents
   </dtml-block>

   <dtml-block anotherblock>
    Another Block
   </dtml-block>
   Other, extraneous text.


then 'templ' will have two block methods that other documents can
access in this way::

   <dtml-var "templ.myblock">              ->  "Block contents"
   <dtml-var "templ.anotherblock">         ->  "Another Block"
   
Any document can also import all of the blocks of a Template into a
local namespace::

   <dtml-with "templ.blocks()">
    <dtml-var myblock>
    <dtml-var anotherblock>
   </dtml-with>

You can also refine blocks using Templates::

   <dtml-block myblock>
    <dtml-var "templ.myblock">
    with more stuff added
   </dtml-block>

   <dtml-var templ>

yields::

   Block contents
   with more stuff added
   Another block


** How is this stuff useful? **

I created Templates because I couldn't design complex and attractive
web pages for Zope using Dreamweaver.  I was always pulling out little
chunks of HTML and putting them into individual methods.  These chunks
weren't valid HTML documents, so I couldn't edit them individually.
With Templates, I create one document with all the HTML code I need,
and block out regions of the HTML using dtml-block.  I upload the
templates (once!) to Zope, and instantly I've changed the definitions
of all the template's block methods.  If I need to make further
changes, I can do it quickly in Dreamweaver.

Templates really makes coherent web design with Zope workable.

Hope this extra explanation helps.

Don't let me discourage you too much.  If you can isolate your Zope, you're
pretty safe.  That means a private or development installation only.  If you
are the only person allowed to touch the management interface, and you
really bite the bullet and do all of your administration through SSL, you
*might* be safe in production.

Right now, they are controlled into oblivion; I have vague plans to allow
some sort of safe import, but no clear idea what would truly be safe other
than trivial "you can use import as another way to spell x = self.foo"
stuff.

That should work well.  XXXPythonMethods and External Methods have very
similar semantics.

I wouldn't recommend it; Changes in the implementation of the authentication
machinery will break this, probably in the next release.  Even if that
weren't true, this trick would be discouraged.  This sort of thing is
*really* best done at the Python level, in a Product.

Subject: [Zope] questions about zope, netscape web server and certificates
Message-ID: <H0001bac07822848@MHS>

Hello all!

I have been posting questions every couple of months concerning digital
certificates and different types of authorization capabilities.  I think I have
finally convinced some people to look at using zope here at work.

Does anyone have any tips or hints for using Zope with Netscape web server on
HP-UX 10.2?  I don't have any way to test this before I get started, and I need
to have my ducks in a row before I start telling someone else how to make Zope
work (I don't have access to the machine that will host Zope).

I have used Zope on WinNT to display data from an Access database, and I have
played around with Zope on Linux (I did not have time to recreate my Access
database on Linux).

One of the things that I am trying to accomplish besides just trying to get
people to use Zope for more general stuff:

1. I need to allow users to login to Zope to approve requests for items (I am
looking at using LoginManager, Wizards and ZopePTK)
2. I need to use digital certificates for authentication (Verisign has a module
for Netscape web server which allows for certificate lookups to verify that the
certifcate is valid and issued by us)
3. I need to pass through the user information from Netscape so that I can keep
track of the user who is approving a request.
4. requests and approvals/denials will probably be stored in a rdbms, but some
information may need to be stored in zodb for searches

Message-ID: <00031510231600.01040@modemcable215.47-200-24.mtl.mc.videotron.net>

Hi everybody,

I'm struggling with some concepts in Zope. The last one is the
DocumentTemplate.HTMLFIle behavior. I was trying to run the Zen 'The (old)
Product API Tutorial' examples when I came accross with this line of code that
looked strange for me (maybe I don't know python enough):

index_html = DocumentTemplate.HTMLFile('poll2.dtml')
...
p = Poll("What's for breakfast?", ['spam', 'eggs', 'toast'])
print p.index_html(p)
------------------^^^

It worked fine and rendered my form.
But what looked strange to me was to give p as an argument. So I tried
p.index_html: it gave me the dtml file (with &lt; for < and so on).

So fine depending on whether or not you provide an argument the rendering is
different. I tried to read the sources to understand better that behavior.

I read somethings about passing mapping object or keywords arguments. But the
question is:
As p.index_html is a DocumentTemplate.HTMLFile instance why can we
provide it with arguments like if it were a method or if we were instantiating a
class?

Hooray! My First Product.

http://www.zope.org/Members/shalabh/iTrack/

iTrack is an Issue Tracking System. It allows a team of people to keep track of
various issues about a project (or anything else under the Sun worth tracking
issues about, for that matter).

Currently this is in development stage (Version 0.2.0) but usable, as long as
you follow the instructions.

Basic Idea:
 o  Issues
 o  FollowUps
 o  Properties of an Issue
     - Title
     - Description
     - Type   (WorkItem, CodeIssue)
     - AssignedTo   (multiple selection of users)
     - Status    (open, closed)
     - (some others not listed)
 o  Types and States configurable through web

For more information:

Hi.

Is there a proposed way how to realize symbolic links in Zope.
I mean, how to place one instance of an object into more than one folder?

This is quite important to information organisation IMHO.

Hooray! My First Product.

http://www.zope.org/Members/shalabh/iTrack/

iTrack is an Issue Tracking System. It allows a team of people to keep track of
various issues about a project (or anything else under the Sun worth traking
issues about, for that matter).

Currently this is in development stage (Version 0.2.0) but usable, as long as
you follow the instructions.

Basic Idea:
 o  Issues
 o  FollowUps
 o  Properties of an Issue
     - Title
     - Description
     - Type   (WorkItem, CodeIssue)
     - AssignedTo   (multiple selection of users)
     - Status    (open, closed)
     - (some others not listed)
 o  Types and States configurable through web

For more information:
http://www.zope.org/Members/shalabh/iTrack/Readme

If you use this, I'd be glad to know.

Enjoy!
Shalabh

Message-ID: <m3k8j4xj0e.fsf@wacko.pdx.net>

With my Zope server crashing about 6 times a day, how can I get the
durned thing to generate a core file?

I have this in my start script:

#! /bin/bash
reldir=`dirname $0`
PYTHONHOME=`cd $reldir; pwd`
export PYTHONHOME
STUPID_LOG_FILE=$PYTHONHOME/var/event.log
export STUPID_LOG_FILE
ulimit -c unlimited
ulimit -a
/usr/bin/python \
     $PYTHONHOME/z2.py \
     "$@"

Which produces this on startup:
core file size (blocks)  unlimited
data seg size (kbytes)   unlimited
file size (blocks)       unlimited
max memory size (kbytes) unlimited
stack size (kbytes)      8192
cpu time (seconds)       unlimited
max user processes       2048
pipe size (512 bytes)    8
open files               1024
virtual memory (kbytes)  2105343

But when I crash with an Aiieeeee error 11, I get no core file.

Box is Redhat 6.1 2.2.12-20.  

I'm able to generate core files from some trashy c code just fine.

Subject: [Zope] newbie - create and call methods ?
Message-ID: <38CFC78F.30634CD9@inpg.fr>

Hello all,

I've been looking in the available zope documentation, listening to
this list, looking in the archive of this list (BTW : are you planning
to add a keyword search ?)... That is to say that I'm used to
searching for the info about open source OS and applications, but I
have to admit I'am almost discouraged using Zope as the doc is really
scarse compared with what is usually found. 

So, sorry, I post my newbie questions :

I would like to create a method to generate a link (href) with a
leading image and text formatting, and so on. I'd like the method to
have two arguments : the name of the link and the URL.

How do I create a method with arguments ?
How do I call a methods with arguments ?
Do I mistake attributes (for docs but not for methods) and arguments ?

If you have pointers to documents I haven't found that...


Thanks in advance,
Greetings,
Eric


PS: Here is what I tryed:
--- DTML method "meth_link"
<h2>
  <dtml-var img_puce_paragraph>
  <a href= "<dtml-var link_url>">
  <dtml-var link_name>
  </a>
</h2>

--- in an other method
<dtml-var name="meth_link" link_name="foo" link_url="la_url">

--- Zope error
Invalid attribute name, "link_name", for tag <dtml-var
name="meth_link" link_name="foo" link_url="la_url">, on line 6 of
txt_user_content

Subject: [Zope] acl_users and differing behaviour with Netscape/IE
Message-ID: <JLEIIKFACBHJPOBKDLODGEEBCAAA.alexander@limi.net>

Hi.

In our development, we stumbled over some behaviour that caused us quite a
headache for a while. We managed to find a less than elegant solution, but
it works for now.

The case is this:

We have the following structure (greatly simplified :)

 rootfolder
  |
  |-images
  |
  |-artists
  |  |
  |  |-acl_users
  |  |
  |  |-Artist1
  |  |-Artist2
  |  |-...etc


As you can see, we have separated the "acl_users"-folder belonging to each
of our artists into the "artists"-hierarchy. All images we use are located
in "images", under the root folder.

The problem appeared when we used DTML similar to the following inside the
artists-folder:

<dtml-with images>
  <dtml-var picture>
</dtml-with>

In IE, this would work just fine, Zope got the "picture" object from the
"images" folder and displayed it - no problem. But with Netscape and
Mozilla, we got authentication problems. It seemed as though Netscape
insists on sending the authentication request no matter what, and is
actually denied access to material that can be read by anybody (ie: the
objects in our "images" folder).

As far as we can see, this is a result of us having an extra "acl_users"
folder in the "artists" folder. Thus the logged in artist is not a user in
the root hierarchy, but only from "artists" and further into the tree.

We've solved this problem temporarily by putting duplicates of the images in
the "artists" folder.

My questions are thus:

1. Should we move the "acl_users" folder to our root folder? If possible, we
would prefer separating the artist users into their own folder, to avoid
clutter. But they should be able to access the rest of the site, like any
anonymous user.

2. Is this a problem with the way Zope authenticates users? Shouldn't users
that don't authenticate correctly at least have access to the content
readable by anonymous users? Or have I done something terribly wrong? :)

You see, we plan on having a "listeners" folder too, where we are going to
store individual listeners' preferences (what artists they want to be
notified of, what music categories they prefer, etc) - and I assume we will
run into the same problems here - users being authenticated only in the
"listeners" folder and below. They should be able to browse the normal web,
however, and add artists to their notify-list. Does this acl_users have to
be in the root user folder too?

Please CC me, as I don't have access to the list at the moment.

Regards,


Alexander Limi.

In the beginning, there was DTML.  DTML did not have expressions as was
designed to look very much like HTML, so names like sequence-item were
chosen.  Later on, expressions were added.  Names like 'sequence-item'
were obviously not going to do, because in a python expression it looks
like a subtraction.  So, the DTML namespace was given the name _, and
given a mapping interface which allowed you to look up names in the
namespace.  Thus was born _['sequence-item'].  _ is a mapping like any
other.

It's really not that bad, just kinda ugly.

I'm running WorldPilot 1.0.4 on Zope 2.14 with the stock IMAP server

RedHat). Everything works fine but I can't create or use new folders.
WorldPilot properly displays the mail in my "Inbox" which is located at
"/var/spool/mail/sbaird" on the server. I can create new mail foldersrs
from within Worldpilot, but I can't access them from WorldPilot (I can
from other IMAP clients). The mail folders created are placed in
"/home/sbaird/" as "INBOX.personal" etc. I suspect this is just a
directory mapping issue but after reading everything I can I can't
figure it out. Any help would be appreciated.

The Python DB API spec 2.0 talks about different levels of thread 
safety. MySQLdb has threadsafety level 1 (= threads my share the 
module but not connections), the ORACLE db has threadsafety level 3 
(= threads may share the module, connections and cursors). I wonder 
what that means in % performance gain in high traffic situations. I 
have no idea where the different levels of threadsafety kick in. Any 
experienced users?

I was rather thinking of connecting directly to ZODB (in a kind of 
server mode) via TCP/IP - not via Zope. But I guess that's an 
aberrant thought that would rather be applicable to connecting to 
ZEO. Still I feel like I'm only beginning to understand but in about 
two weeks the new production site must be ready running zope ;)

Actually I'm not planning anything except to be prepared. I'm only 
starting and have no idea what I will end up with. So of course I am 
looking for a scalable solution. From what I've learned from the list 
scalability seems to be a weak spot of Zope (while e.g. the latest 
Enhydra includes a failover solution). I have no idea how much ZEO 
costs. (People from DC could you help here? I couldn't find a price 
on the website.)

I tried to understand ZClasses and read the documentation a couple of 
times but it didn't help a lot. So now I'm using Python classes which 
is very easy (maybe only because it's better documented). Can you 
e.g. simply add a dictionary or a list of dictionaries to a ZClass 
and access each element individually?

Would be nice if I could get back to you some time later to talk 
about the PCA. :)

Subject: [Zope] Need help with site structure
Message-ID: <NDBBKGBPJMFODAAFNMKEGECMCAAA.mduvall_22030@yahoo.com>

I'm setting up a Zope site, and would like to know if the approach described
below makes sense. I imagine this is a no-brainer for the more experienced,
but I'd appreciate some feedback so I don't go too far afield. Thank you!

In a nutshell, the site will give customers the ability to run reports
against application data that we're hosting for them. There will also be an
area for developers to log on and tweak parameters of the hosted app.

User Management
---------------
To keep the user accounts organized, I'd like each customer organization
(say, ABC Corporation) to have a folder that contains an acl_users folder.
I'd merely prefer to look at a few users at a time instead of seeing them
all together.

When a users logs on, I'd like that user to have a role of custUser,
custAdmin, or custDeveloper. I'd define these roles at the root. I'd also
like the user to acquire (if that's the term) properties of the customer
account, such as customer ID, so customer ID would be a property of the
customer folder(?).

So folder-wise there'd be;
root/customers (containing...)
root/customers/abc_corp
              /...
root/customers/xyz_corp (each with an acl_users folder)

Site Content
------------
This side of the site seems straightforward. The user's role will determine
what's visible/accessible, and the user's acquired customer ID will
determine which application data can be included in reports.

root/mysite (will contain content sub-folders, such as...)
root/mysite/eggs
           /spam
           /reports
           /developers (custDeveloper role required for access)
           (more content sub-folders)

So the question is...
---------------------
My main question is the user authorization / acquisition piece. How do I run
username and password through the contents of the root/customers folder?

If the folder layout described above makes sense, is this authorization
piece a job for a ZSQL Method, for GUF, or for both? Last week's "virtual
folders / url's" thread provided interesting info ZSQL Methods.

Also, any comments about holes or vulnerabilities in this approach are
welcome.

Thank you.

Mitch Duvall

Message-ID: <38CFD0D8.B5391DC8@funcom.com>

I've seen numerous postings about this, but so far I have been
unsuccessful in successfully subclassing the Image with my own ZClass
(called VProduct for this case). Here's what I have managed to do:

* Create my new VProduct ZClass with Image as a base class
* Add a couple of new simple (string) properties to VProduct
* Modify the VProduct_add and VProduct_addForm methods so that my new
properties gets asked for and filled in (and using the system clock to
generate  unique id's)

This seem to work great, and I can move about in the Zope filesystem and
add instances of my VProduct class as I want to.

I have not been able to successfully integrate the file upload feature.
What I have done is:

* Add an input file <input type=file name=file> in the addForm method
* Putting a file name in this field and pressing submit button

From here I am not quite sure what to do with the image, but from
browsing earlier postings about this, it seems to have something to do
with calling manage_upload one way or the other.

In the VProduct_add method, I have the following special code:

<dtml-call "REQUEST.set('ts', ZopeTime ())">
<dtml-call "REQUEST.set('id', _.str(_.int('ts')))">

The above code generates a unique id for my VProduct instances, and this
works fine.

Inside the automatically generated:

<dtml-with "VProduct.createInObjectManager(REQUEST['id'], REQUEST)">

further down in the VProduct_add method I have the following stuff:

  <dtml-call "propertysheets.Basic.mange_editProperties (REQUEST)">

that code should take care of modifying the properties of my VProduct
instance (and assumes I guess that the input field names match the
property names). This seams to work great.

Right before the "propertysheets..." line I have tried adding the
following:

  <dtml-call "manage_upload(REQUEST['file'])"> 

It does not generate an error. But it does not seem to manage the upload
part either, since my VProduct instance gets the content_type
"text/plain" (instead of image/jpeg which is the right type for the jpeg
file I try to upload). And when I try to "view" the VProduct instance, I
get a simple <img src="91231912" alt="sometext"> tag which displays like
a missing image in a web browser (no wonder since the content_type is
wrong). I have tried manually setting the content_type to "image/jpeg",
but the image still does not display correctly. My guess is that the
image never got uploaded.

Any ideas on how to handle the upload properly? I've done some 30
searches through the list archive, without any clear answers to how the
image uploads are handled (or should be handled). I've looked carefully
through the howto's but have not found anything.

Any help would be appreciated.

What I know is that you have to use Named Parameters in method

ex:
myFunction(url, image):
    return '<A HREF=%s><IMG SRC=%s></A>' % (url, image)

and the dtml call looks like :

<dtml-var "myFunction(url='http://www.zope.org', image='logo.gif')">

I am not sure of all...But I think it is the "spirit"...

Good luck !

You don't.  But that's what you were asking so that's what I was
answering.

I don't think the problem is that a transaction needs to be commited,
the problem is that the DA is engineered to block until it completes the
task at hand.  Even if you did call get_transaction().commit() from
python or an external method or whatever, I don't think it would unblock
your call.  You can try it, of course.

I don't know if we have immediate plans to bring the ODBC DA up to level
3.  Probably not any time soon unless it is a customer requirement.

Another option is to threadsafe the ODBC DA yourself.

I know, I know. :) But how otherwise do I get you people
to come out from hiding without posting a hack like that? :)

GUF has problems and we have to face it. If a product takes
a few days to install, if a product locks newbies up and send
them into panic attack, it has problems. Please just look
up past postings in the mailing list... headers like "Bad...
very bad" and "GenericUserFolder has locked me out" are
just heartbreaking. :)

If I have time I'll find something better, or make something
better. :)

Evan:

(1) When the the next version of Zope coming out?
    It fixes a tiny bug that I reported. :)
    Will it have a native feature like SiteAccess that
    you have mentioned before?

(2) Could you describe briefly how the traverse machinery
    works in Zope? I'd like to take a look into it. Which
    Python files are involved?

regards!

The boundary tag is implemented in the MIMETools product.  Because it is
only meaningful in the context of the mime tag, I did not explicitly
list it in the readme.

I'm not certain if the MySQL DA is level 3 (threaded) or not.  I am
certain that MySQL does not support transactions and Zope does.  What
this means is, if you call some SQL and later on an error occours, Zope
will "roll back the transaction" and discard any changes you made in
Zope.  If Zope is used with Oracle, Sybase, ODBC, Postgress or any other
database that supports transactions, then those databases will
synchronize transaction commits and rollbacks with Zope.  This means
that your data is allways consistent across databases, which is a good
thing.

This may not effect you.  Your database may be entirely read only, in
which case it's not a problem at all.  Just keep in mind that you are
missing an important piece.

Keep in mind that this is not an _relational_ database.  It's an object
database.

Yep.  You can access the ZODB through HTTP, FTP, XML-RPC and WebDAV. 
That's really what Zope is, it's a network aware application on top of
an object database.

The question is really too vague to get a specific answer.

Well, it's syntactically correct.  Whether or not it does what you want
it to do we can't tell because you didn't say what you want to do.

The expression "'PROENG' and 'MATRIX'"  will _allways_ return 'MATRIX'. 
So 'OK' will only be rendered if OUTPUT == 'MATRIX'.  In fact, this:

<dtml-if "OUTPUT == 'MATRIX'">
  OK
<dtml-if>

does exactly the same things as your code.

There apears to be a segment violation somewhere in Zope which was

Subject: [Zope] Zope and enterprise data access
Message-ID: <4.2.2.20000315131747.00ba5600@saladin.aisys.com>

The company I work for is starting to get more requests for web sites which 
need to have access to enterprise data.  We have several Java people on 
staff and most of these projects are currently being done (or planned to be 
done) using JSP/Servlets and Enterprise Java Beans.  The problem that I 
have with this solution is that there is very little in the way of content 
management available in this environment, without rolling your own.  What I 
would really like to be able to do is build the client interface using 
Zope, so I can easily blend static content, dynamic content and content 
management, with access to enterprise data.  I know that Enterprise Java 
Beans are accessible via CORBA, so theoretically it should be possible to 
access this data through Zope/Python.

My basic question is this, is there anything available (free or otherwise) 
which would make it fairly easy for Zope to interact with something like 
Enterprise Java Beans?  Are other people trying to use Zope in an 
environment where access to enterprise data is important?  If so, are there 
other solutions to this problem?  What I would really like to be able to do 
is use Zope in combination with a DBMS to build smaller systems, but when 
the need arises, I would like to be able to scale things up to allow for 
distributed data object access.

Any thoughts, suggestions or comments on this subject?

Thanks.

Hmm.. unfortunatly there is no good way to do this from DTML except to
use manage_FTPget().  Yuk.  This lack will be fixed in the near future
when we re-do alot of the Zope interfaces.  Currently we are in the
middle of documenting all of the existing interfaces which obviously
must come first.

I *think* you want REQUEST['file'].read().  manage_upload wants a string

You can create your own kind of splitter and replace Zope's (note that
Zope's splitter is written in C, and is found in
lib/python/SearchIndex/Splitter.c) you can write yours in C or Python.

I have not touched the authentication machinery yet so I must rely on
other Zopistas efforts. There is a LoginManager which is part of the PTK.
Seems to be well thought out, and it seems to provide a very general and
broad solution to the authentication problem, but I have no idea whether
or how it works.

Another useful add on is for GUF to ship  a complete example of its usage
based on standard Zope objects (Folders etc). Maybe as an exported
folder that the user can optionally import.

I would solve this in the submit action by doing a select for the data before
doing an insert.

Example:

(form_html)

<form action="submit_html" method=post>
....
</form>

(submit_html)

<dtml-in select_data>
<dtml-if sequence-start>
<dtml-var error_message>
</dtml-if>
<dtml-else>
<dtml-call insert_data>
</dtml-in>

Dan,

It's gotta be a connection string or username/password problem as
defined in your interfaces file.  Are you sure the port number of the
remote server is correct in the interfaces file?  You can use isql from
the box that Zope is on to connect to the remote Sybase server?

First off let me say that I have searched the Zope archives.  I finally

Dan,

You need to install the Sybase client libraries on your Zope machine to
use the SybaseDA.

For more info, please contact the Zope mailing list at

I guess I'm confused.  I can't get to the actual jpeg image?  Here's what I'm
trying to do.  I want to create a form to upload data.  This data can be off any
type.  The data is stored in an ODBC database table along with it's mime type.
So, on the upload action form, I need to 1)  get the mime type and 2) get the
actual data.  Another part of the site mails off these items as attachments.
I've heard that the mime type should be uploaded along with the data, I just
don't know how to get to it.

You have a few (untested) choices:

1) Put the following in a DTML Document or Method:

     <dtml-call expr="REQUEST.set('first_sequence', [1, 2, 3])">
     First:<br>
     <dtml-in first_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

     <dtml-let second_sequence="[1, 2, 3]">
       Second:<br>
       <dtml-in second_sequence>
         <dtml-var sequence-index>: <dtml-var sequence-item>
       </dtml-in>
     </dtml-let>

2) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Tokens". Give it the value "1 2 3". Put this as the document
   source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

3) Create a DTML Document. Add a "my_sequence" property to the document of
   type "Lines". Give it the value:

     1
     2
     3

   and put the following as the document source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

4) We could make a Python base class
   (lib/python/Products/MyClassBase/MyClassBase.py):

     class MyClassBase:
       def __init__(self):
         self.my_sequence = [1, 2, 3]

   and create a file (lib/python/Products/MyBase/__init__.py):

     from MyClassBase import MyClassBase

     def initialize(context):
       context.registerBaseClass(MyClassBase, 'MyClassBase')

   Now restart your Zope, go to the Control Panel, and Add a new product
   called "MyClass". Inside this product, create a ZClass called
   "MyClass". When creating the ZClass, select MyClassBase as a base
   class. In this ZClass, on the Methods tab, create a DTML Method
   (say, index_html) with the following source:

     <dtml-in my_sequence>
       <dtml-var sequence-index>: <dtml-var sequence-item>
     </dtml-in>

   Then, go to your root, drop an instance of MyClass with an id of
   "MyInstance". Now, navigate to http://your.server.com/MyInstance.
   Voila.

I probably missed two or three other ways to to it. But, I hope one of
these is what you're looking for.

Not directly from DTML.  You need to use a method on the Image object. 
manage_FTPget().

This is different from the first question that you asked.  In this case,
when your form uploads the file contents, ZPublisher will marshal that
into a StringIO object (which acts just like a python file object).  In
this case you can just do:

<dtml-var "REQUEST['name_of_form_element_that_is_the_file'].read()">

and get the 'contents' of the file.

In this case, your taking about a Zope 'Image' object, _not_ a standard
file object like you get when you upload data.  For this you need
manage_FTPget().

Has anyone noticed their dtml code mysteriously reverting to a previous

In other words suppose you have a dtml document called DocA. It
contains:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Several days later you change
DocA to:

<!--#var standard_html_header-->
<h1><!--#var id--></h1>
<!--#var standard_html_footer-->

You test this doc and it displays fine. Later that day or several days
later, after a manual shutdown and restart, DocA has reverted to:

<!--#var standard_html_header-->
<h1><!--#var document_title--></h1>
<!--#var standard_html_footer-->

Ok, I guess this is where I get confused. When is the REQUEST['file']
instance
a string and when is it not? If I try to replace the manage_upload call
with
your suggestion, I get a message saying:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which indicates that REQUEST['file'] is a string at this stage (and
probably
the filename or similar). From the input form I guess "file" is a string
(at
least that is what it looks like in the input form - the filename) at
least
until I press the submit button. When it actually changes from the
filename
to a file I do not know.

Any other suggestions on how to get hold of that file?

Thanks,

Marius Kjeldahl

Your form element should be:

<input type=file name="file_name:file">

The ':file' is necessary to marshal the file into a file object.  I was
going on the assumption that you had done that otherwise as you've
discovered it will turn it into a string, which you may or may not want.

MySQL takes a lot of criticism because it is (a) non-free, (b)
non-transactional. Non-fre I won't get into.

Non-transactional means that it doesn't support transactions. :) So what
are transactions? Say you own a bank and Joe transfers $50 from his
checking account to his savings account. The program removes $50 from
this checking account, but the disk is out of space and an error occurs
putting it into a savings account. Is Joe out $50? Not if it was a
"transaction" where all-or-none of a sequence of events happens. If at
any point an error occurs in the transaction, everything is rolled back
($50 is back in his checking account and the error is reported). MySQL's
lack of transactions rule it out IF you need transactions.

Another limitation of MySQL is that it doesn't support very large
databases. This usually isn't an issue.

Another solution is PostgreSQL, which is a free relational database
system (see http://www.postgresql.org). Postgres is very powerful and is
probably the most powerful free db by far! There are some drawbacks:
 * Last I heard, the PYTHON INTERFACE (not PG itself) for postgresql is
not threads compliant. You will have to kludge something with locks to
use it(?)... any ideas on this one, anyone?
 * You cannot remove or modify a column on your database. You can rename
the column and let it hang, or recreate the table. For changing schemes,
this can be a real pain.
 * Text beyond 16K must be stored in a large object - this is a pain.

It has some advantages:
 * Transactions
 * Super docs
 * Great reliability
 * Most of ANSI SQL Compliance
 * Stored procedures
 * Some real nice datatypes for everything from money to geometry

Alas, there is Oracle8i. It has some drawbacks:
 * Installation is a bitch! You usually have to edit kernel header
files, recompile, set mount points, apply patches, arg!!
 * Complexity; Oracle VERY complex even after you get it up and running
 * The Oracle/ZOPE interface does not have a Setup file for 8i. You'll
have to write one to compile it. (Or, email me for the one I got a hold
of)
 * Fewer column types than postgres

And the advantages:
 * Transactions, great reliability, and great SQL support
 * Java support
 * Plenty of docs. My favorite Oracle stuff is at photo.net (the web
page of some MIT guy)
 * Good interfacing with Zope, thread safe

In general, if you're willing to spend the overhead of a killer learning
curve, use Oracle8i.

Ok, I have changed my form element to what you suggested. These are the
results I am getting with various <dtml-call> tags in the VProduct_add
method (called after filling in VProduct_addForm):

* <dtml-call "REQUEST['file'].read ()">

Error Type: TypeError
Error Value: argument file was ommitted

I guess this is because no field in the form is named 'file'. So I try:

* <dtml-call "REQUEST['file_name'].read ()">

..and I get the same error. I even tried to name="file:file" in the form
element, and using REQUEST['file'].read () in the call, but then I get:

Error Type: AttributeError
Error Value: 'string' object has no attribute 'read'

which I guess means that it now has the 'file' variable, but it is still
a string.

Any other pointers, or references to where I can read more about the
file stuff?

Thanks in advance,

Marius Kjeldahl

REQUEST['file'].read ()
                    ^
            Notice this space?

That space isn't supposed to be there.  You're supposed to be calling a
function with no arguments, the () has to be right next to the "read". 
The way you have it right now, it's looking for an attribute called read
instead of a function.

Actually you can get the image data as <dtml-var "my_image.data"> where
"my_image" is the name of your image object.

The following DTML will return the actual image to a browser (tested):

<dtml-call "REQUEST.set('Content-Type', my_image.content_type)"><dtml-var
"my_image.data">

It is crucial that the DTML method contain no extra whitespace, though, as this
will be interpreted as part of the image data.

Message-ID: <Pine.BSF.4.21.0003151720200.1009-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively (but I'm willing to share).


Announcements

  * The latest versions of the Zope Content Managers Guide, Z SQL
    Method User's Guide and DTML Reference Guides is available in
    postscript(ps) format.  With luck, the technical problems of the
    previous versions have been fixed.

    http://www.zope.org/Members/Pam/PSversion

  * Check out the new Zope Documentation Projects page that lists
    current Zope documentation projects and their status.

    http://www.zope.org/Documentation/Projects/Projects

  * Martijn Faassen <faassen@vet.uu.nl> has established a Zope-XML
    mailing list.  The intent is to discuss Zope's XML infrastructure.

    http://www.egroups.com/group/zope-xml/info.html


New Products

  * Software Product: iTrack Issue Tracker Product, by "shalabh"

    iTrack allows a team of people to keep track of various issues
    about a project. Currently this is in development stage (Version
    0.2.0) but usable, as long as you follow the instructions.

    http://www.zope.org/Members/shalabh/iTrack/

  * Software Product: ZGDChart Product, by "teyc"

    ZGDChart uses gdchart to draw charts.  This product comes with
    Windows binaries and source for non-Windows platforms.  This
    initial development release is 0.3.

    http://www.zope.org/Members/teyc/ZGDChart

  * Software Product: DTMLTemplate, by "halazar"

    DTML Templates are documents that allow blocks of text to be named
    and made available to other documents. The basic building block of
    templates is the DTML block tag, which can also be used with other
    DTML document types. Templates export their blocks. Another new
    tag, the suppress tag, allows block definition without rendering.

    http://www.zope.org/Members/halazar/Products/DTMLTemplate


Updates

  * Software Product: jcNTUserFolder, by Jephte CLAIN

    This product authenticates Zope users against an NT domain
    controller.  All users are encouraged to upgrade to this version,
    0.0.3.  Unfortunately, the upgrade is incompatible.  You will lose
    any role settings.

    http://www.zope.org/Members/jephte/jcNTUserFolder


Zope.org items

  * How-To: The Debugger Is Your Friend, by Michel Pelletier

    This HowTo is an invaluable resource for those days where if I get
    one more mysterious traceback, just one more and I swear I'll
    crack.  It explains how to step through Zope code line-by-line
    with the python debugger.

    http://www.zope.org/Members/michel/HowTos/TheDebuggerIsYourFriend

  * How-To: How to test your products without (re)starting Zope, by "teyc"

    This HowTo describes testing Zope products within a python
    interpreter without starting the Zope server.  This rather speeds
    up the code-test-curse-code cycle, because it allows you to
    quickly reload your Product with each change.

Message-ID: <B4F57760.14F5%Jatwood@bwanazulia.com>

I have some data returned by a SQL Method that I want to randomly pick from.
Since I cannot get the SQL Statement to return random data sets I was going
to use the "_.whrandom.choice" to go over the SQL list and create a new list
of the randomized choices.


This will go over the SQL Content
<dtml-in sqlMethod size=10 start=query_start>
</dtml-in>

But how do I create a list? (in Python I would just say list = () and a
list.append()

TIA,

Hi..

I just uploaded many files with load_site (thanks Itamar!), but
I ran out of disk space while doing this.
Seems as the last transaction corrupted the Database seriously.
When I try to delete the folder where the errors are I get:
Error Type: CorruptedDataError
Error Value:

The same with packing database.

And when invoking Undo, i get something like:
long int too long to convert

Any ideas what I could do to repair my database and deelete the corrupted
folders and start over again?

Thanks in advance,
    Mario

Havn't been able to so far. It seems you have to have a reasonably complete

That is a possible option. Does anyone know what the issues with this are?
From memory I think the non-thread-safeness of the odbc drivers themselves
was not the only problem. I suspect the python odbc interface might have
been not thread safe also. Can anyone confirm this?

Dan,

Please cc the Zope list while we're talking about this.

What is the -H option to isql?

Can you import the sybase module from python as per the build
instructions?

What user are you running Zope as?  Does that user have permissions to
the sybase client directory?

Hi

i've spent the day trying to make this work so i thought i'd see if
brighter minds could illuminate the darkness of my night.

I'm trying to setup an email archiving system in Zope. I've got the
email retrieval setup in an separate python script and a couple of
ZClasses setup in Zope to archive/catalog the emails. My problem is
getting the parsed email info(to, from, body, etc) from the external
script into my Zclasses. i've tried xml-rpc but i keep getting server
errors. i connect to the server and try

zope.project.archive.addEmail(id)

but i keep getting a 500 Internal server error message. addEmail is just
a wrapper around the constructor which expects only one parameter the id
of the email Zclass object to create( just something to debug before i
pass in all the params). So what gives? i can call the method from the
web with

http://localhost/project/archive/addEmail?id=xx

but how do you call a dtml method with args from xml-rpc. fyi i'm using
amos's patched xmlrpclib for authentication (i fixed the import errors)

i've trying to reimplement this in an external methods but i would
really like to know how to do it with xml-rpc. btw 

Thanks

Kapil

The Login Manager looks good because, unlike GUF and UserDb, it allowed
me to use the admin/supervisor password to authenticate straight away 
and so didn't lock me out of the directory.
I actually gave up on GUF because I _couldn't_ get it to let me in in
the first place to set up my db methods. The password that is supposed
to be built in didn't work at all, neither did the supervisor one.

To me this is the biggest problem with the other existing systems, that
they lock you out of your site and there is little you can do about it.
(In UserDb I had to comment out parts of the security code to get it
to let me in and set it up properly. After it was set up it worked fine
and I could put the code back.)

All authentication stuff from a database is going to require the
person to customise their own sql we can't make custom authentication
methods any easier than that, but in the simplest case this should
be _all_ they have to do. The supervisor password should _always_ work
in any authentication method from the beginning and it should be made
clear that people are going to have to authenticate using that particular
password until they have the rest of their site set up.

Anyway, the LoginManager looks very clean. It already doesn't have a
lot of the old problems and I like the abstraction. Now I just have to
finish getting DCOracle working (annoying truncated .so files...).

Yeah that was probably me, not to slam MySQL, it's fast, it's free, and
it's stable.  It's lack of transactions however means that you have to
be aware of and live with the possibilty of inconsistent states of data
between MySQL and Zope.

For read only operations, or low-write, or if an external application
handles inserting your data and Zope only reads it, this is not really a
problem.  Also, it's only really manifest if you change the database and
then change something in Zope and an error occours.  If you can isolate
your SQL calls as much as possible, then this shouldn't be a problem.

I posted a work around for that on this mailing list a couple of days ago.
And yes whilst it is frustrating it is no where near as hard as writing 
an authentication product from scratch (which from experience is difficult).

Last time I used it came with a very simple example already. All you need
to do is add in your logic and you're away. The SQL Howto on the website is
very informative (cheers to whoever wrote that).

Sorry I think that the GUF is also very clean and quite easy to work with.

I think GUF is great as it is. Thanks a lot to Zen for contributing it.

I would have to recommend postgresql. I've got a prototype ecommerce site 
running with Zope at the front, some python in the middle and postgresql
at the backend. Currently it is a prototype so we only have about 20,000
items in there at the moment however it seems to work very well. (Once I 
brushed up on some of my SQL).

Check it out at http://www.postgresql.org

I see a couple of issues with this:

1)  This may not scale well; if select_data becomes large you may
be spending a while in the dtml-in loop.

2)  There could still be a race condition here, between the check for
data and the insertion (especially coupled with the above point - the
probability would increase proportionally with the load of the machine
and the size of the table). I say "could" here (guardedly :-), because
I don't know how Zope's transaction semantics are implemented, and how
they affect the DA that you're using (does anyone have any pointers to
documents?  I've just started reading "How to Write a DA", and this
mentions the distributed commit protocol).

I'm not sure if a solution to the original problem is to surround
the insert with a <dtml-try> tag;  I'm going to try this myself
sometime today (if I get some spare time :-).

My experience with SyBase is that the adapter development is
kind of slow, and only Linux platform is supported. And
currently it has some glitches with some data types (decimal
with 10 or more digits), it does not support stored procedures,
and the implementation in Zope 2.1.4 crashes when you have
date fields ending between 59 and 60 seconds (e.g: 59.23 sec).
Also, when there is database problem, the adapter very often
just hangs and lock the database out, requiring a Zope reboot.

So, SyBase in Zope is not really in great shape. I don't know
about other databases, maybe other database adapters have
problems, too. SyBase adapter is workable for me (after I
patched the problem areas), just not that great in its current
shape. It has transaction, though, which you definitely want.
The thing is, SyBase itself seems fairly solid, it's just the
Zope adapter that is still not perfect.

Hung Jung

Subject: [Zope] DateTime exceptions
Message-ID: <00031611243805.02516@localhost.localdomain>

Greetings,

A workmate of mine has had this problem also, and now it's happened to me.

I cannot catch exceptions from the DateTime object!

My code:

<dtml-try>
    <dtml-call "REQUEST.set('delDate','%s/%s/%s' % (delYear, delMon, delDay) )">
<dtml-except>
    <dtml-call "REQUEST.set('delDate',0)">
    <font bgcolor="red">You have entered an invalid date.</font>
    <dtml-call "REQUEST.set('Error',1)">
</dtml-try>

Now, from my understanding, this should catch ALL exceptions.  So why, when i
give invalid values (like -1) does ZOPE give me an error page?

Is this some deficiency in the way the DateTime object handles exceptions?  Or
is there some funamental zen i'm not groking?

I would write the select_data query to only select a single record, i.e. the one
I'm worried about duplicating.

Heh. I certainly wouldn't want to do it from scratch myself...
I just tracked down your work around again and now remember why it didn't
help me. I actually have a UserDb in my root directory and that's what I'm
trying to get rid of (Since I'm moving to Oracle anyway I thought I'd
change to a supported product since UserDb has been giving me a few obscure
problems at times.) So since it doesn't support the admin user either your
suggestion doesn't help. I will, however, try making a normal user folder
in a subdirectory and then try to set GUF up in a subdirectory of that...

Grin. Seeing I never managed to get into GUF's management interface in the
first place I can't really comment on how clean it is.

IIRC, all you need is the libraires, a seperate download. I have a
couple machines that only have the libraries, and work just fine. Of
course, they are on various unixen, YYMV on NT.

Firstly, I'm not a member of this mailing list, although I have an archive
of over 2000 messages from it.  Could anyone replying to my message please
reply to tim_haines@hotmail.com as well as the list?  Thanks.


I've been developing a site using nt4, Access, and the odbc plugin.  Things
work great - most of the time.

I've noticed that occaisionally I get any error message that mentions
tpc_begin.  When I do a refresh, the problem is gone, and the site works
fine again.  I've also noticed that this normally occurs the first time a
database query is executed after a reboot.

Does anyone know why this would happen, or have any insights at all?  I look
forward to hearing from you.

Tim.

One thing I should point out firstly is that the LoginManager inside
the PTK isn't finished yet and the developers don't suggest actually
using it just yet.

While I said it looks great (and it does) and it accepts the admin
password it does _not_ yet have the api in place to let you authenticate
from SQL. So you probably want to wait a bit still.

But after saying that if you still want to look at how they are going
you need to actually install the Portal Tool Kit first.
Have a look at it's install instructions at:

Can you provide more specific detials? I am running two seperate systems

Hello.

Many thanks to all for your answers on my recent question about MIMETools.
Really, tag <!--#boundary --> is implemented now, and works, but...
I need sending mail with multiple file attachement...
Combination of several tags <!--#boundary --> working...
When I tryed insert tag <!--#boundary --> into tag <!--#in -->,
Zope said: "Unexpected tag, for tag <!--#boundary ..."
Because <!--#boundary --> is only meaningful in the context of the 
<!--#mime --> tag.
We have loss of this context? Below example of my stupid code.

[ --- begin code snippet ---]

<!--#mime type=text/plain encode=7bit -->
just example text...

<!-- #in "files_to_mail" -->
<!--#boundary type=application/octet-stream disposition=attachment 
encode=base64-->
<!--#var sequence-item -->
<!-- #/in -->

<!--#/mime -->

[ --- end code snippet ---]

Any ideas?

Dima.

Are you just afeter a single random item from a ZSQL query? 
If so:

<dtml-with "_.whrandom.choice(_['getcategories'])">
	<dtml-var category>
</dtml-with>

Works for me. In this case, 'getcategories' is a ZSQL method that
returns a list of categories, consisting of:
"select category from linkCategories"

Message-ID: <38D077D6.CC74ABB3@suprize.com>

Hi,

    Zope seems to evaluate expressions in an unconventional way.
Say I have three properties, a=3, b=5, c=7 set in a Folder. In
a DTML Document I tried to say <dtml-var "a/b*c"> and got result
0. The expression was evaluated as a/(b*c) and rounded off. Is
not the expression supposed to be evaluated as (a/b)*3? The
result is not correct still if we put it this way:
<dtml-var "(a/b)*3">. I still got 0 as the result. Did I miss
anything fundamentally or is this a, bug?

Hi Zopistas,

I now that the failure is because the object in the namespace is "PARENTS". So what is the name of the root folder?

Hi,

    Suppose the following folder/Obj structure:

		Zope Root
		    - test
                        showImage     (DTML Document)
		        - image
			    testImage (image object)
		    - test2
                        testProgram   (DTML Document)

    showImage contains one line of code:
       <A HREF="test"><dtml-var "image.testImage"></A> 
    that shows the testImage properly alone. But if I put
    <dtml-var "test.showImage"> in testProgram (in test2),
    I got all "<" as "&lt;" and the ugly code like the
    following was returned intead of the image with link.

&lt;A HREF=&quot;test.html&quot;&gt;&lt;dtml-var
&quot;testImg&quot;&gt;&lt;/A&gt;

    I have tried the following but none works out:
	- Use DTML Method instead of DTML Document to hold
	  showImage
	- Use "/" instead of "." to point to objects
	- Use single quote or no quote instead of double quotes

    Please advise the proper way to resolve this annoying issue.
    Thanks a lot!

Most of the unfinshed pieces have to do with giving users
propertysheets. That makes it not quite useful for PTK yet.

I'd say for non-PTK use it's in pretty good shape.  Would I recommend
using it currently? Well, for a production sight, I think maybe it's a
bit too new.  It could stand more testing and security review.  But, if
you're developing a site that you don't need to go live tomorrow, I
say sure, go for it. It's quite useable for non-PTK applications.

Sure it does! Got a SQL-based GUF? You should be able to take your GUF
userExists/userRoles/userAuthenticate/etc methods and plop them
unchanged into a LoginManager Generic User Source (GUS), and have it
Just Work. 

You're probably thinking of the comment that it's not ready to do
SQL-based PTKs. This is because the propertysheet support that PTK needs
isn't there for SQL. But, that's a feature that no other SQL-based
userfolder has anyway -- it's a new thing, and at the moment only PTK
needs it.

Sadly, the way DTML tags work right now, this isn't possible.  Since
'boundary' is part of the 'mime' tag, like 'else' is part of 'if', you can't
put it inside another tag.  The only workaround I can think of is pretty
nasty; look at the source for MIMETag and use the MimeWriter class directly.
It's not that bad, unless you don't know Python...

Urk.  First, we can pick this apart in at least two ways:

<dtml-with "PARENTS[-1]">

or

<dtml-let rootObject="PARENTS[-1]">

In either case, the part in quotes takes the last element of PARENTS, giving
you the root folder.  In the first case, we use this directly in a
"dtml-with", and can refer to properties and contents of the root folder
inside it.  In the second case, we give the root folder the local name
'rootObject' which we can then use to access it.

Evan @ digicool & 4-am

You've run into a misfeature of Python.  Since 'a' and 'b' are integers,
'a/b' is performed as an integer division.

Thus 'a/b*c' == '(3/5)*7' == '(0)*7' == '0'.  If you want floating point
division, you need to make 'a' or 'b' a float, either directly or by writing
'_.float(a)/b*c'.

Cheers,

Subject: [Zope] Version bug?
Message-ID: <38D10EEF.156ABF9E@globalcrossing.com>

Greetings!

I think I may have found a bug in the way Zope handles versions.
To recreate:

1) Set up a version, say, "TestVersion."
2) Rename the version to something else, say, "NewTestVersion."
3) This breaks the following:
   * When you enter the version, the "you are working in" line displays
     "TestVersion"
   * The "Version Management" Control Panel link shows TestVersion as
     well (this breaks the link, too)
   * Any file modified by the version shows up as TestVersion, too.

This happens on:
  Zope version: Zope 2.1.4 (binary release, python 1.5.2, linux2-x86)

Is this a bug?

Hi Zopistas,
	Thank you for the answers. My problem arose because I was passing a DTML Method a list of strings: [ 'PARENTS[-1]', 'FolderA', ...]. And while I could do:
	<dtml-with "_( folderObject=_.getitem('FolderA'))">
I could not do the same with 'PARENTS[-1]'. The simple solution suggested by your answers is to just pass the objects themselves (duh!): [ PARENTS[-1], FolderA, ...].
	But out of curiosity I'm still wondering if there is a way to refer to the root folder by name so one could write
	_.getitem( 'rootFolderName' )

Subject: [Zope] How do I set properties from DTML? (Repost)
Message-ID: <00031617290300.13146@promotor>

I'm reposting due to mail problems ...

I'm working on a thing I'll probably call "ZBox"; it's a "widget
method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Sure, you just need to trace my previous postings. :)

SyBase adapter has two specific problems that I have ran
into. They are both 100% reproduceable and both have been
reported to the Collector. One of them is now fixed for
Zope 2.1.5 (the _validTime thing.) The other one still sits
still waiting for Digicool to fix it. If I say the development
of the adapter has been slow, it's because it's been slow. If
I alone have been able to find (and fix) two problems
and one limitation, somehow I don't think they are the
only problems and limitation. :)

Some of the bugs are later found independently by other
people, too. (See below.)

Many people also say that they have zero problems with
Microsoft Windows. I guess they just have been lucky. Ha ha.
But just because one person is lucky, it doesn't mean the
rest of the world is equally lucky. :) Let me teach you
how to para-phrase your question:

"Can you provide more specific details? I am running two
separate system with Sybase, and I would like to know more
about these problems."

Very nice. The following are three articles in chronological order.

Subject: [Zope] XML-RPC Woes
References: <38D0221B.794D6C3A@wm.edu>
Message-ID: <38D129D3.B15C9835@wm.edu>

After getting a few private emails with questions about what i was doing
i thought i'd share what i'd learned and some code.

First an apology, i read through my original email and realized that i
was a bit to vague to really get any help, mainly because i don't
understand what i'm passing through xml-rpc to dtml methods that are
expecting Zope stuff (client, mapping, kw).

Second, what i'm doing. I'm creating an email archive in zope. i wrote
up some python code that retrieves/parses email from a pop3 server and
then inserts via xml-rpc into a zclass so that it can be archived and
cataloged. I got the whole thing working last night by passing the
parsed info in a dict via xml-rpc to an external method which
took care of adding the Zclasses in Zope, basically following the
example from this howto http://www.zope.org/Members/teyc/howxmlrpc

Third, How to do XML-RPC with Amos's patched xmlrpclib.py for
Authentication:
    1. Assuming you already have the original xmlrpc implementation from
pythonware.com installed, copy Amos's xmlrpclib.py over it (WARNING this
will basically delete the original).

    2. Fix the subclassing error. Find 
	class BasicAuthTransport(xmlrpclib.Transport):
	and change it to
 	class BasicAuthTransport(Transport):

    3. Fix the import error. after the comments there are some imports
add:
	from base64 import encodestring



<dtml-with Standard_Code_Disclaimer>
all code is provided on as is basis for the purpose of an example. use
at your own risk.

Fourth. External Method Code:

	def import_mail(self, props):
		id = props['id']
	mailobj=
#netscape mangles this line
self.manage_addProduct['YourProduct'].YourZClass.createInObjectManager(id,
self.REQUEST)

	mailobj.propertysheets.YourPropertySheet.manage_changeProperties(props)
	return "Zope is Cool"


this is one of those times you just look at zope and sigh. so much power
if you know how to use it. i actually got the basis of this code from
the Zope CD that they passed out at the python conference(8). this
method is part of the archive folder called below.

Fifth. The XML-RPC call: from the python script without error checking

        self.zope = xmlrpclib.Server(YourZopeServer,
                            xmlrpclib.BasicAuthTransport(userid, passwd)

        Props = {
            'Id':Whrandom.Randint(0,1000000),
            'To':Prop_list[0],
            'From':Prop_list[1],
            'Subject':Prop_list[2],
            'Date':Prop_list[3],
            'Body':Prop_list[4]
            }
        Print Self.Zope.Test_project.Archive.import_mail(Props) 


</dtml-with>


I hope this helps. if anyone has any examples of passing args to dtml
methods via xml-rpc i'd love to see them. 

Cheers,

Kapil

No, its integer :)
3/5 is 0, anything multiplicated with 0 will be 0.
so 3/5*7 is 0 no matter where you set brackets :)
Integer does not round, it only cuts off everything after the "."

Eventually you want: a=3.0, b=5.0 and c=7.0
(even only one variable beeing "float" wuld be sufficient)

so far so good. But how to I add items to the dictionary?

Okay, I *think* I am beginning to grok zclasses, but I have a couple
of questions:

What is the scope/namespace of a ZClass' methods?  In my tests, I
cannot access other methods of the same ZClass.  I *can* access
methods in parent folders of my ZClass, but not the current folder.
Ie: Create ZClass called zcTest.  Create two methods in this ZClass,
called index_html and test.  Neither can see the other.

Secondly, when I try to access anything off of instances of my zclass
except for property sheets, I get access denied.  Where do I set up
the permissions to allow my methods to be viewable?

Subject: [Zope] ZODB question, again
Message-ID: <38D13016.6F9160EC@sage.att.com>

ok, persistent fool that i am, i'm still trying to figure out
how to use ZODB in an External Method to do some simple (ha!)
database stuff.

so i built a very simple app, to implement a counter.
each time you invoke the "Count" method, you get a number
back, and it increments.

running the script (see below) by hand, it works fine.
referencing it from Zope, using this dtml fragment:

	<dtml-var "Count( 'chickens' )">

or just pointing my browser at:
http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=chickens

to reference an External Method called Count, which 
refers to the Count function in this script, i get:

   Error Type: AttributeError
   Error Value: Counter

if i then click the reload button, i get:

   Could not lock the database file. There must be another
   process that has opened the file. 

and i'm locked out until i restart zope.
can someone please help?  this is getting really
discouraging.  a simple explanation of where i'm 
going wrong would be greatly appreciated.  a small
working example of a working app would be terrific.

thanks


--------------------------------------------------------------
script follows:

import ZODB, ZODB.FileStorage
import Persistence

class Counter(Persistence.Persistent):
	"""A Persistent Counter"""
	def __init__( self, name ):
		self.name = name
		self.value = 0

def Count( name ):
	"Get counter value, then increment, creating if necessary"

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/CountDB.fs' ) )
	connection = db.open()
	root = connection.root()

	if not root.has_key( name ):
		counter = Counter( name )
		root[ name ] = counter
	else:	counter = root[ name ]

	counter.value = counter.value + 1
	
	get_transaction().commit()
	connection.close()
	return counter.value

if __name__ == '__main__':

I'm able to get Zope to dump a core file if run in debug mode ('-D').  I
haven't proved this, but I suspect that when a fork()ed child dies it
does not dump a core file.  Since debug mode does not cause Zope to fork
off Zope as a child from the parent watchdog, a core file is produced. 
None of this is mentioned on the fork() man page, or the clone() man
page, or whatever.  I probably need a good UNIX programming reference to
verify it.

Give it a try, fire up Zope in debug mode and run your load scripts
against it to reproduce your segfault.

Message-ID: <4.2.2.20000316001051.00a9f710@postoffice.pacbell.net>

I am having trouble with userDB cookie authentication in IE 5 through the 
@Home network. Apparently @Home uses a proxy server for all of their 
traffic. When accessing the docLogin page for authentication the user 
receives a "Cannot Display This Page" error from IE 5. Turning off 
cookie-based authentication seems to solve the problem. This problem does 
not occur in Netscape under the same conditions and does not occur in IE 5 
when used outside of the @Home proxy.  Does anyone know of specific 
problems with IE 5 and proxy servers? Is there any solution outside of 
using standard authentication?

Try this

<dtml-var "_.float(a)/_.float(b)*_.float(c)">

You calculation is using integers and there is no automatic conversion being
done.

You need to explicitly tell zope that you want float calculations.

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:


ERROR(200) ZServer uncaptured python exception, closing channel
<zhttp_server listening :8080 at 81f5b90>

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

You cannot open the object database twice.  In this case, Zope opens it
first, and then you open it second (why you are getting the
AttributeError I don't know, a traceback there would help).

Basically what you are doing is sort-of a no-no unless you know what you
are doing.  First, a database cannot be opened twice, even from the same
process.  Second, you do not need to open the database again, because it
is already open and accessible to you from your external method:

def anExtMeth(self):
  connection = self._p_jar

All persistent objects (in this case, 'self' being the container of the
external method, probably a Folder) have an _p_jar attribute which is
their connection to the database.  Always use that instead of opening
your own.

Also, you need to be very careful with what you are doing.  You are
inserting objects right into the root level of the object database, this
is not really a good idea.  For example, let's say you fix your code to
not open the database again and you get it working.  Then (don't!) try
this URL:

http://kestrel.sage.att.com:8080/Garry/ZODB/Count?name=Application

Doh!  Guess what?  You just trampled your entire Zope, hosed the entire
enchilada, because Zope also lives in that top level namespace, and its
name is 'Application'.

Pick your own name (like GarryHodgsonApplication) and assign your
counter objects as sub-attributes of that.

Subject: [Zope] Zope Cookie Handling
Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF373@ap3expr3applge.appl.ge.com>

All,

Here is another interesting issue that I have encountered while trying to
process cookies in Zope.

On a different app. server I have a Java class which generates an encrypted
cookie when a user logs into the site.  When the user navigates over to my
Zope site, I wish to check the value of the UID.  I do this by retrieving
the cookie within the following snippet of DTML:

<dtml-if "REQUEST.cookies.has_key('UID')">
		<dtml-call "REQUEST.set('cookie',
REQUEST.cookies.values())">
		<dtml-var "validateCookie(REQUEST, REQUEST['REMOTE_ADDR'])">
</dtml-if>	

This DTML calls a DTML method (validateCookie) which in turn is calling the
following External Python Method:

import xmlrpclib, base64

def validateUID(self, REQUEST, ipaddr):
        cookie = REQUEST.get('cookie')
        servlet =
xmlrpclib.Server("http://salesnet-dev.appl.ge.com/geaservlet/X
mlRpcTest")
        cookie = repr(cookie)
        cookie = cookie[2:]
        cookie = cookie[:-2]
        return servlet.validateCookie.check(cookie, ipaddr) 

This XML-RPC call attempts to invoke the Java decrypt method.  Herein lies
the problem:

Upon investigation of the value contained in the UID cookie, Zope returned
the following:
\316\313\321\310\316\315\314\311\321\312\316\317\317\223\310\321\315\317\313
\316\317'

If I print out each character created during the Java encrypt method, the
following values are returned:

\206\203\209\200\etc.etc.

A colleague of mine pointed out that Zope was returning the values in Octal
rather than decimal.

Is this behavior by design?  Is there another mechanism I can use to
retrieve the raw cookie value before Zope places it in a dictionary?  Rather
than code a string parsing routine in Java, are there any suggestions as to
how to convert each character back to decimal, or obtain the string prior to
being converted into octal?

Once again, I appreciate the assistance/responses.  Everyone on this group
has been wonderful to interact with.

-Brian

This apears to be fixed in the CVS.  The reason is dispatcher.accept may
return None if the accept() sys call returns EWOULDBLOCK.

Assignment cannot be done in DTML, it is a security risk.  DTML was not
designed to be a general purpose programming language; it's meant to be
a reporting language.  Use python (either external methods or
PythonMethods) if you want to do this.

Subject: [Zope] Problem with ZODBCDA
Message-ID: <38B478360010B51B@smtp.visto.com> (added by administrator@visto.com)

I just installed ZODBCDA on a new Windows install of Zope 2.1.4 using ZServer running as an NT service.  After editing db.py to fix the THUNK typo (I've submitted that to the collector) it sees the System ODBC DSNs that exist, and it lets me pick one.  But when I try to open the connection, it tells me I have an invalid connect string.  The weird thing is that I turned on Windows ODBC tracing, and NOTHING is being logged from the Zope connection.  So I don't think it is actually passing anything to ODBC.  If I do the same thing from some other ODBC client, the connect string works and the session gets logged by the ODBS tracer.

There was a very similar problem in the list archives several months ago, and it seemed that running the service as a user, instead of the system, fixed the problem.  Didn't work for me.

Any suggestions on how to track this down further, or better yet to fix it, would be appreciated.

Message-ID: <38B478360010BA29@smtp.visto.com> (added by administrator@visto.com)

Within the last half-hour I posted that ZODBCDA connections were not working correctly on my machine, with Zope running as an NT service.

I rebooted the computer and now the connection gets made. (I hadn't rebooted since I changed the user the service was supposed to be running as.)  So with the Zope service running as me, rather than as the system, it seems fine.
And now my problem is exactly the same as the one in the archives last year.  This doesn't seem too serious, but if anyone knows why it cares who Zope is running as, I'd still like to know.

Thanks,

Fortunately MySQL has transactions high up on the todo list (but it's

Zope doesn't do anything above and beyond what python does.

Python rounds integers, quite simply:

Python 1.5.2 (#0, Apr 13 1999, 10:51:12) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> 1/2
0
>>> 3/5*7
0
>>> (3/5)*7
0
>>> 3/(5*7)
0
>>> 

integers as input gives an integer as output.  Obviously there are two
schools of thought on this.  If you want a floating point number, use
'float()' (or in DTML, _.float())

>>> float(1)/float(2)
0.5
>>>

<dtml-with "PARENTS[-1]">
	<dtml-var rootProperty>
</dtml-with>

should do the trick - although you have access to rootProperty in any case
because of acquisition:

<dtml-var rootProperty>

Uups, sorry

<dtml-var "test.showImage(_.None, _)">
           ^^^^^^^^^^^^^^ 

but i think you have to call also

<A HREF="test"><dtml-var "image.testImage()"></A>

How can I access this database through ZOPE.

When I try to make the MySQLDA extension a lot of errors come out of it
:

Can you help me ?


Does DigitalCreation have a solution on connecting to MySQL on a Linux
Platform (thanks to ODBC or something else).

Thanks in advance.

You have to convert it from integer to float. Try:

<dtml-var "(_.float(a)/b)*c"> 

Though you're rigth, you need the parenthesis for the correct
evaluation.

Hello there

I' ve got some difficulties with the very final step of ZOPE-Installation:
I made the start-script as root (-> python wo_pcgi.py) and got all the neccessary scripts. Then I chown and chgrp all files to my ZOPE-user and tried to start up the server. Unfortunately the script has got some endless-loop or so and I have to break (Ctrl-C) in order to get my prompt and logout. I do have access to the server via WWW but only until I break the script. 

Do you know some hint?
Thank you very much!

The root folder can indeed be accessed by PARENTS[-1].

<dtml-with "PARENTS[-1]">

is all you need.

Keep in mind also that if the property of the root folder you're trying to
get at has a unique name, you can get to it via acquisition. (If the
property is called "foo", <dtml-var foo> would look up the property and find
it, all the way at the root.)

After running a couple of Zope sites during development for about a month
(Zope 2.1.4 installed from source, ZServer on port 8080, ZMySQLDA,
PythonMethods, RedHat 6.1), we've seen the server report the following error
while running in debug mode (-D) a couple of times:

Is there someone who is familiar with the innards of ZServer who can give me
some idea of what is causing these? Thanks.

Your properties look like integers, and I believe that is your problem. Try
this:

<dtml-var "_.float(a)/b*c">

By converting a to a float and then doing the rest of the expression, python
should consider the whole expression to be floating point.

Subject: [Zope] BIG ZODB - Scalability
Message-ID: <E12Vac2-0001CF-00@home.delysid.org>

Hi.

I just got the job to find out how we (the technical university Graz)
could build up a large image-database for different users..
Zope came to my mind because of its oject oriented structure.
And because I'd really like to do Zope work at work :).

I now have to find out how Zope can be used with really large
databases.
(100000 to 1mio objects theoretically in the future).

Can anyone provide me with URLs or information on:
The relational Database Storage Manager (couldnt find any references)
  (is this intented for large databases?)
Or splitting the Zope hirarchy into multiple ZODB FileStorage Manager
instances. SO that I could e.g. save on subfolder of the root folder
in on data.fs and the next subfolder in another data.fs

I am thinking of the filesize limit of some operating systems.
2GB isnt really much.

I think that a FileStorage would be better for our content (images),
because performance issues (never saved 20GB in an relational database before :) )

Any help is appreciated,

There are three errors here :-)

First, Python atribution doesn't return the value like C. The
value of "myObject = 1" is None.

Second, as you said, 'PARENTS[-1]' is not an object. Using
_.getitem Zope will look for an object with this name, which
doesn't exist.

Third, there is absolutely no reason for the _.getitem.

What you want can be acomplished with:

<dtml-with "PARENTS[-1]">
   ...
</dtml-with>

or

<dtml-let rootObject="PARENTS[-1]">
   ...
</dtml-let>

depending on what it is you want. :-)


Also note that if you're using SiteAccess' virtual hosting,
PARENTS[-1] will (IIRC) not give you the root folder, but the
virtual root.

testProgram should *call* the showImage method, otherwise you just insert a
string representation of it.

<dtml-var "test.showImage(_.None, _)">

Thanks, I've never accessed the CVS. How soon might the fix show up in a
release? (Or is there a simple change I can make to one of the .py files
until that happens?)

I would implement this whole thing as a Python product and avoid mucking around
directly with the persistence machinery altogether. This would allow you to add
a Counter object anywhere in the Zope tree.

import OFS, Persistence

class Counter(OFS.SimpleItem.Item, Persistence.Persistent):

    def __init__(self, id, title):
        self.id = id
        self.title = title
        self.counters = {}

    def Count(self, name):
        if not self.counters.has_key(name):
            self.counters[name] = 0
        v = self.counters[name] + 1
        self.counters[name] = v
        return v

manage_addCounterForm=HTMLFile('methodAdd', globals())

def manage_addCounter(self, id, title, REQUEST=None):
    ob = Counter(id, title)
    self._setObject(id, ob)
    return self.manage_main(self, REQUEST)


Add a Counter call 'counter' to a folder, then call:

<dtml-var "counter.Count('chickens')">

Subject: [Zope] New LocalFS Release
Message-ID: <03f001bf8f8f$4dcdee20$eb0217ac@dev.prognet.com>

Version 0.1.6 of LocalFS is out. I'm calling this one the Ides of March
release. :)

New in v0.1.6:

 - Fixed a bug with filtering in directory browse view.

 - Fixed bogus text/html content-type on non-HTML files.

 - Use a more aggressive search to determine whether files are 
   binary or text. This causes directory browsing to take a bit 
   longer but hopefully prevents file corruption problems.

 - Added a Properties tab which allows specifying custom properties.

 - Improved the formatting of directory browse view again with tables.

 - Convert .xml files to XMLDocument objects if the XMLDocument 
   product is installed.

 - Convert .stx files to StructuredDocument objects if the 
   StructuredDocument product is installed.


In 0.1.7 I'm adding fully-customizable mapping of file extensions to
content-types, Zope object classes, and icons in the directory browse view.
Hopefully that should be out pretty soon as well.

<dtml-if "_.string.find(ua,'MSIE') != -1">
 <dtml-comment>

  <dtml-call "REQUEST.set('iMSIE4',_.None)">
 </dtml-if>

  <dtml-call "REQUEST.set('bMSIE4',1)">

  <dtml-call "REQUEST.set('minorVer',ua[iMSIE4+8])">
  <dtml-if bMSIE4>
   <dtml-if "minorVer == 'p' or minorVer == 'b'">
    <dtml-call "REQUEST.set('bMSIE4_beta',1)">
   </dtml-if>
   <dtml-if "minorVer == '1'">
    <dtml-call "REQUEST.set('bMSIE4_01',1)">
   </dtml-if>
  </dtml-if>
 </dtml-if>
 <dtml-if "_.string.find(ua,'MSIE 5') != -1">
  <dtml-call "REQUEST.set('bMSIE5',1)">
 </dtml-if>
<dtml-else>
 <dtml-comment>
  Let's assume netscape
 </dtml-comment>
 <dtml-call "REQUEST.set('bNetscape',1)">
 <dtml-if "ua[8] >= '4'">
  <dtml-call "REQUEST.set('bNetscape_4',1)">
 <dtml-elif "ua[8] >= '3'">

 <dtml-else>
  <dtml-call "REQUEST.set('bNetscape_2',1)">
 </dtml-if>
</dtml-if>


Include this in your standard_html_header and then use the variables in your
pages as normal,so:

<dtml-if bNetscape_4>
  do netscape specific stuff
<dtml-elif bMSIE4_01>
  do IE specific stuff
</dtml-if>

Hello Olivier,

Thank you for your help. The call to the method seems ok, but the code
of the method is displayed instead of been executed. May be is it a
code for external method ? Other things to do instead copying the code
to the DTML method code window in the Zope interface ?

Anyway, could someone please post an exemple of an DTML method
accepting parameters - that is the code to put in the proper windows
in the Zope interface - or a pointer to a document explaining how to
proceed ?

Thanks in advance,
Greetings,
Eric

I don't know.  Further, I'm not sure if the fix is in the 2.1 branch. 
Possibly not, so you'll have to wait until 2.2 which has no release data
set and will probably go through a thorough beta period.

Not really.  Check out the zope site under Resources and read the
instructions on how to check out code from the CVS.  You could probably
get away with replacing your ZServer/medusa directory with the CVS
version, but don't be suprised if that doesn't work.  In fact, if you
aren't confident about that or don't know how to use cvs or don't know
python, I don't recommend you do that at all.

Subject: [Zope] Subclassing ZObjectManager in ZClasses
Message-ID: <4.2.0.58.20000316233055.0163ae70@192.168.0.2>

[Repost - previous message was truncated.]


Hello,


I've been playing with ZClasses and I ran into an issue with ZObjectManager.

Summary: (when creating a folderish ZClass and cascading base classes) if 
ZObjectManager isn't subclassed at 1st level, objects can be added to the 
folderish ZClass instances but they don't show in the manage_main object list.

[Zope 2.1.4 on Win32, pure ZClasses, no Python around]

More details:

1) I first tried this simple setup. It worked fine:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyTestClass

MyTestClass is folderish and works as expected.


2) This setup worked fine too:

ZClass_for_CatalogAware
ZClass_for_Renderable
ZObjectManager
   |
   |_MyBaseClass
     |_MyTestClass1
     |_MyTestClass2

I can create a custom base class and use it in several ZClasses. They are 
folderish and work as expected.


3) Then I tried this setup:

ZClass_for_CatalogAware
ZClass_for_Renderable
   |
   |_MyBaseClass
   |_ZObjectManager
      |_MyTestClass

Here I first created MyBaseClass, then I subclassed it together with 
ZObjectManager when creating MyTestClass.

MyTestClass looked OK; I created a Content view linked to manage_main; I 
allowed adding standard object types such as Folder and File.

However, when I add objects in an instance of MyTestClass they do not show 
in the object list (Content view). I *think* they are actually added 
because I cannot add an additional one with the same ID: I get an "ID 
already in use" error.

When testing further I got the same results when CatalogAware and 
Renderable were not around. Same results too when subclassing Folder instead.

It's not that bad, but I can't create a standard base class, then use it to 
create a folderish variant.

Does anyone understand why?


Cheers.

Alexandre

Your pattern is ^/Zope/(.*).  The ^ means match the beginning of the
'script path'.  So, this pattern will match:

http://www.test.net/Zope/

Keep in mind this will NOT match http://www.test.net/Zope (without a
terminating /).  If you want to match:

http://www.test.net/

The use the pattern ^/(.*)

You many need to play with the initial /s a bit.  Various versions of
mod_rewrite have done this different ways, some versions match ^ up to
the first /, and some don't.

Do note the rewrite documentation at 
http://www.apache.org/docs/mod/mod_rewrite.html

``The great thing about mod_rewrite is it gives you all the
configurability and flexibility of Sendmail. The downside to mod_rewrite
is that it gives you all the configurability and flexibility of
Sendmail.''

Message-ID: <20000317004314.A1830@owl.rhein-zeitung.de>

Hi,

I am currently developing a new product for my company using Zope. No I am
running into a problem. I like to use the building user management and user
auth features, but I also need add to some new properties to a user record.
Nothing big just a few properties, that a relevant for some user specific
configuration parameters.

Can I add new properties to an User object, or do I have to create a new
UserFolder and new User object using ZClasses? The later wouldn't be very
satisfying. Or can I just create my own type of user and add it to any user
folder? Especially the buildin user folder of Zope?

Bye, Oliver Andrich

If you're using the 'start' script, background it:

Has anyone else seen this type of message.  We've been assuming they are
simply people hitting the stop button on the browser thus terminating

The Z SQL Methods User's Guide

This shows you everything you need to know to do things the Zope way. It assumes
you have a basic understanding of HTML forms and the SQL language.

I have gone a little bit down the road toward a design for this:

  http://www.zope.org/Members/tseaver/CosNaming

I also have some hackish code on my local box which exercises a tiny portion of
the design.  The code is too ugly to release, but I do hope to be working on it
over the next few weeks.  There are a couple of other folks on the list
interested in CORBA as well -- I'll CC them in case they have gotten further off
the dime than I have, and would therefore be able to bump your comfort factor up
a bit higher.  Perhaps we should set up another list for this topic?

There is a special piece of syntactic sugar for one-based numbering::

  <dtml-in "_.range(x)">
    <option><dtml-var sequence-number></option><br>
  </dtml-in>

(See $ZOPE_HOME/lib/python/DocumentTemplate/DT_InSV.py for more grubby details).

Subject: [Zope] External Methods and REQUEST
Message-ID: <38D1A522.E70421A6@picknowl.com.au>

Greetings,

I've started having a serious fiddle with External Methods, and have
run across a couple of brain issues:

1)  Most examples I've seen (well, both :-) pass REQUEST as a parameter
in addition to self (for example, def frobnicate(self, REQUEST)).  Yet
I've noticed that I can pull REQUEST out of self's namespace, and they
appear identical.  Is there a reason for passing in REQUEST explicitly?

2)  (And if this is related to point #1, then you may beat me around the
head with a Nerf bat).  I defined an external method called frobnicate
as follows:

def frobnicate(self):
    "One of many test functions"
    return self.REQUEST.form

and install it.  If I call it with http://localhost/zope/frobnicate?foo=bar
it returns a dictionary of {'foo' : 'bar'}, as it should.  If I call
it without any arguments as http://localhost/zope/frobnicate the
browser hangs and eventually times out with "The document contained no
data".  I'm specifically interested in form data here, which is why I
haven't used the REQUEST['thingo'] idiom, so I suspect I must be
accessing REQUEST incorrectly.  Any clues would be most welcome (if
only someone could write a ZenOfZope product; I'd download it into my
brain in an instant! :-)

  Daryl Tester

Overview

I am trying to put an XML structure into a Zope product that mirrors the=
 hierarchy.

The dtd for the XML is roughly of the form
<!ELEMENT nodes (node)*>
<!ELEMENT node (node|leaf)*>
<!ELEMENT leaf (object)*>
<!ELEMENT object EMPTY> 

The 4 elements share several attributes and each has some unique=
 attributes. So the intent is to group the common attributes in a couple of=
 property pages and create an property page for each individual element.

The desired ZClass representation is as follows:
container (object manager)
    base () {to contain common property pages}
    nodes (object manager, base)
        node (object manager, base)
            leaf (object manager, base)
                 object()

I build the hierarchy, set permissions as follows and do the factory edit=
 button trick
container - add_nodes
nodes - add_node
node - add_node, add_twigs
twigs - add_objects

I instantiate a container, 
add a nodes object to the container, 
add a node to th nodes.

At this point I can only add twigs though I think I should be able to add=
 nodes. I thought I would look at the SubOjbects list however the only=
 object that appears in the Subobjects list is nodes.

Am I missing something here? I have tried countless permutations with and=
 without the base class, deriving base from object manager etc... I think=
 one of my prior iterations actually worked but without the base class=
 concept though I seem unable to reproduce it now...

Does anyone have any ideas?

Thanks 
Bob

I am not sure what is going on but wouldn't it be generally safer if your
java class converts the encrypted cookie in some ASCII text format first?
I think that will solve your Zope problem too.

In general the process is:

- create a database adapter
- create a zsql method to do the insert
- create an html form to submit the data
- create a dtml method to call the zsql method as the form's submit action

Here's a pretty good how-to that describes the entire process in detail.

I find these pages to be an essential reference for zsql:

Hi Jeff.

Can you post the traceback. If this is the error I think it is then it may be
related to what you set as your SMTP server when you created the WorldPilot
object. One thing I found that works reliably is to specify   localhost  for
the SMTP and IMAP servers. 

BTW which IMAP server are you running? and what is your SMTP server?

Good Luck!

Being explicit.  Also, your method might not (depending on how you use
it) be being called from ZPublisher (in which case REQUEST is not
passed, it must be acquired), then again, your method might not be in an
acquisition context either, in which case you must pass it.  In 99% of
the cases however, you can do either.

Well, hanging is probably not the best way for Zope to handle this
situation, why it hangs I couldn't tell you (perhaps you should post
that to the collector).  However, form data usualy comes from a POST,
and here your doing a GET, passing a query string.

You can still get form data that way, the form attribute of REQUEST is
when you want to make sure you're definatly getting a value from a form
and not some other namespace.

I went ahead and wrote a Java helper class to convert from base 8 to base
10.  This has resolved the problem.  For those interested:

private static String convert(String uid)
	{
		
		StringBuffer sb = new StringBuffer();
		StringTokenizer octalString = new StringTokenizer(uid, "\\",
false);
		Integer convert = new Integer(1);

		while(octalString.hasMoreTokens())
		{
	
sb.append((char)convert.parseInt(octalString.nextToken(), 8));

		}	
		return(sb.toString());
	}

I am still curious as to why Zope converts the data into base 8.

Thanks for your response.

I keep forgetting that Zope is a collection of products :-(.  One day,
I do intend to spend more quality time with the source and how the
components interact.

Oddly, it only appears to do that when I call the external method
directly.  If I place <dtml-var "frobnicate(REQUEST)"> (modified to
pass in REQUEST explicitly) into a Method or Document and request
that without parameters, it comes up immediately and correctly.
Odd.

Will do.

Ahh, differing semantics.  I'm used to Python's cgi.py (and Perl's
cgi.pm, from memory) treating POSTs and GETs with query strings
the same.  The only way of telling the difference was by looking
at the REQUEST_METHOD (if you cared enough, that is).

This was my concern - REQUEST's namespace seems a little crowded, and I
was worried about clashing identifiers.

Hold the phone!  I've just constructed a document that basically does
<dtml-var REQUEST>, and invoked it with a query string, and the
parameters DO show up in REQUEST.form.  Are you pulling the wool over
my eyes, Michel?  :-)

Regards,
  Daryl Tester

PS - The recent "Virtual folders / URL" thread solution you proposed
was _very_ enlightening, but yet reading about direct traversal in
the ZSQL manual didn't provide anywhere near the same lightbulb factor.
Could Digital Creations consider adding that in as an example?

Message-ID: <7502CAC76F59D211B0090000F8662FA3072CF372@ap3expr3applge.appl.ge.com>

All,

Have been trying to add File Attachment functionality to the ZDiscussions
Product.  Thus far, I have modded the ZDiscussions.py file, specifically the
ZDItem class's __init__ method, to accept one extra parameter called file.
The corresponding DTML-Method (postForm) within the ZDiscussion object has
been modded to include a FILE input field.

To facilitate the file handling, I am using the Squishfile.py module.  All
is working well, and via a new def attachment(self) method that was added to
the ZDiscussion.py module, I am able to return the file to the browser.

Herein lies the problem.  How can I reference the file via an HREF?  With
the following DTML:

<dtml-if attachment> 
	<b>Hello there</B>
	<tr><th bgcolor="#d0d0f0" align=left>Attachment:</th><td>
	<dtml-in attachment>		
		<A HREF="./<dtml-var file_name url_quote>">  
		<IMG SRC="<dtml-var SCRIPT_NAME >/<dtml-var icon >"
HEIGHT=16  
		  WIDTH=16 BORDER="0" ALT="Click to download
attachment"></A>    
		<A HREF="./<dtml-var file_name url_quote>">  
		<dtml-var file_name></A>   
		<dtml-var file_kbytes>KB (<dtml-var file_bytes> bytes)<BR>  
	</dtml-in attachment></td>
</dtml-if>

This of course references the file object as
absolute_url/ZDItem_id/file_name.  This same reference url is used in the
Squishdot product when displaying a link the user may click on to download
the file.  However, in my implementation it is not referencing the file.

The only way to reference the file is to use <dtml-var attachment>, which
means that the file will be streamed to the user as soon as they click on
the message thread, obviously not the way I would like to handle the
situation.

Do I need to include the file object as a property of the message?  I
thought by including the file object during the creation (__init__) method
of ZDItem this would be handled.

Any/all assistance would be greatly appreciated.  Also, if I am crazy for
doing this please let me know.  Perhaps a new ZDiscussion already exists
that supports attachments?

Thanks again,
-Brian

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,

Michael Bernstein.

I've been asking for this sort of capability for about a year now (I
even offered to cough up real money to get it in) and got nowhere.

Tha last time I brought this up was in November
(http://lists.zope.org/pipermail/zope/1999-November/013362.html), but
I've refined what i think needs to be done a bit, bear with me because
it's still a little fuzzy (I'm aware that the following proposal has
some serious handwaving in it):

Zope needs a new folder in the control panel (call it 'Relationships')
that contains 'Relationship' objects.

'Relationship' objects come in two flavors: one-to-many, and
many-to-many. you define what meta types are allowed on either side of
the relationship in it. All relationships are bi-directional.


ZClasses that subclass 'relationship_aware' get a new tab labeled
'Relationships', which is automatically populated with any
'Relationship' objects that it finds. appropriate 'edit' methods should
be automatically generated.

in the ZClass instance, Relationships should behave much the same as
property sheets, except that you can traverse them to get at the
properties of the objects on the other side. The trick is, the
information about the relationship between two objects is not maintained
in either of them, but in the 'Relationship' object instead.

Example:

Two Zclasses are built, called 'Book' and 'Person'. Both subclass
'relationship_aware'. an 'Author' Relationship object (many-to-many) is
added to the 'Relationships' control panel folder. The 'Author'
Relationship allows object of meta type 'book' on one side of the
relationship, and objects of meta type 'Person' on the other.

Now you go back to the 'Book' and 'Person' ZClasses, and under the
'Relationship' tab you generate add/edit methods for the 'Author'
Relationship that the ZClasses can now discover.

As you may have noticed, both the 'Relationships' Folder and the
'Relationship' objects it contains bear some resemblance to ZCatalog.

Because we defined the 'Author' relationship to be many-to-many, 'Book's
can now have multiple  'Person's associated with them and 'Person's can
have multiple 'Book's.

Ideally you would now be able to do this after having set the neccessary
associations within the ZClass instances:

from within a 'Book' index_html method:

Written by:
<dtml-in Author>
<dtml-var name>
</dtml-in>


And from within a 'Person' index_html method:

<dtml-if Author>
<dtml-var name> has written:
<dtml-in Author>
<dtml-var title>
</dtml-in>
</dtml-if>

We can elaborate on this model to allow 'Person' objects to also be
associated with a 'Book' through an 'Editor' relationship, allow
'Person' objects to be associated with each other through an
'in_rolodex' relationship, etc.

This approach has various advantages, not the least of which is that
because neither object is responsible for maintaining the relationship
information, you don't have to worry too much about what happens when
one of the objects is deleted.

Another is that if one object sets the association up, the object on the
other side of the relationship is immediately aware of it as well (as
long as it too is relationship_aware). My favorite advantage is the
simplicity of the DTML that results from the named relationship being
traversable.

Let me know what you think,


[RH]Michael,

What you seem to be descibing is some sort of an internal Zope 'link base'
as they exist for may hypertext systems (but zopish). This would be very
useful.
I do have some doubts about your desciption, however:

- would the generic relationships (meta-type<->meta-type) you describe be
the best way to go and whether they would turn out to be very useful. You
also do not mention one-to-one relationships; I'm sure this is not on
purpose, but this could be implemented quite simply by a specific python
product.

- I also wonder whether much of what you describe cannot also be achieved in
other ways, mainly through using the Catalog (as you indicated yourself). If
I may speculate a bit more on this point: what you want may be a specialized
folder index method that uses a mix of its own objectValues and Catalog
obtained objectvalues for its contents. If you wanted to use symlink type
relations, this may be done by using properties (this is more or less
generic) or by using the values of a 'link base' type of object (see above).
THis last would be very specific: pointing to specific objects.

- The idea of relationship aware is nice, but the drawback is that it can
only be true for derived ZClasses, and not all zope objects are Zclasses.

- In ZDP list many of these subjects have been in question for some time
now. You may want to have a look at the list archives of last month for many
of the discussions and of course the implementation of ZDP Tools by Maik
Roeder (available somewhere from his member page:
http://www.zope.org/Members/roeder)

Hi,

Wasn't it generally agreed that storing a counter in a ZODB was a bad idea 'cos of the high number
of refreshes, and hence the number of transactions stored in DB?

Basically, because of the undo/rollback capability of ZODB, the data.fs grows rapidly if you use it
to do counter-type things.

Or an I wrong?

I am using Zope for an large  project at the moment. For static content, 
such as images, I use apache to server them up (and will probably move
to something faster such as thttpd or kernel mode http server) and then just store
a URL reference to the actual data. This leaves zope to do presenatation, which it
does really  well and let a more suitable server handle the static content.
Any way, I'm not saying that zope couldn't handle this however depending on
 your exact use this may be an option for you.

Cheers,

Benno

You can help yourself by consulting the archives of this mailing
list:

The solution is to patch MySQLmodule.c to make it compliant with
mysql.h of newer versions of MySQL.

You can find my (unofficial) patch in the archives of the mailing

DTML-LET is meant for renaming expressions, like a macro

      <dtml-let name="bob"
                relation="uncle">
        <dtml-var name> is your <dtml-var relation>
      </dtml-let>

what actually gets evaluated is <dtml-var "bob"> is your <dtml-var "uncle">,
which is nice.


the other part <dtml-let x=5 y=7>

is rewritten to <dtml-var 5><dtml-var 7>

which is not nice at all as there is no variables called 5 and 7.

OTOH 

      <dtml-let x="5" y="7">
        <dtml-var x><dtml-var y>
      </dtml-let>

should run fine as then x and y are expressions and not variables 
so 
<dtml-var x><dtml-var y> is <dtml-var "5"><dtml-var "7"> which runs fine.

Subject: [Zope] security question
Message-ID: <001401bf900d$0e049860$1464a8c0@sabine>

hello:

for my zope, the root directory is protected so that anonymous users have no
permissions.  in addition to root, two other users are defined and given the
role 'internal'.  one of the users has a username/password.  the other
allows access based upon IP range.  this works as intended.

i now want to give anonymous users permission to access
/subfolder/index_html.  this dtml method accesses a database and uses
LocalFS.

my first attempt to realize this was to assign the appropriate permissions
to Anonymous for index_html.  when this failed, i went to the /subfolder
security and modified permissions there that seemed relevant.  i tried many
combinations until finally giving up and granting all available permissions
to Anonymous at the /subfolder and /subfolder/index_html levels.  so now,
all permissions are checked for 'acquire' and for 'Anonymous'.

even this does not work!  users attempting to access
http://myzope/subfolder/index_html are greeted with an authentication
dialog.

so, despite the fact that security seems to be a pretty simple concept i
seem to be missing something fundamental.

any insight would be appreciated.

thanks,
bac

Security is never a simple concept, especially in system as complex as Zope.

Some decent documentation would help ;-)

Stupid bug :-)
here is the patch against
lib/python/Products/jcNTUserFolder/NTUserFolder.py:

164a165
>         userobjects = filter(None, userobjects)


if you don't have patch.exe (which is likely to be the case, as you run Zope
on Windows...), the above patch means that you have to add the line
userobjects = filter(None, userobjects) at line 165 of the file so the code:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        return userobjects

is turned into:

    def getUsers(self):
        """ Return a list of *local* user objects
        Only users whose settings are not to be acquired are returned
        XXX should I include the defined ntdomain users ?
        """
        userobjects = []
        resume = 1
        while resume:
            users, junk, resume = win32net.NetUserEnum(None, 0, ...
            userobjects.extend(map(lambda user, self=self: self ...
        userobjects = filter(None, userobjects)
        return userobjects

You could also download the latest jcNTUserFolder-0.0.4 at
http://www.zope.org/Members/jephte/jcNTUserFolder

Remember: Zope must run as a service or the user have "act as part of the
operating system" for jcNTUserFolder to work!

[I'm posting this again because, suprisingly, there was no response]


I was reading the thread about Zope vs AOLServer and performance
and threading and all that.  

I've done some work with other interpreters embedded in the apache
child processes (tcl, mod-perl) so I started wondering if this would
work for zope.  Somewhere I think there is a Python interpreter
embedded a'la mod-perl.  If not, I'm pretty sure it can be done
without too much grief, using mod-perl and mod-dtcl as starting
points or examples.

It seems to me this would allow utilization of multiple processors,
esp for apps with a database backend, since the work would be split up
over n frontend apache server processes and n backend database
processes (at least for oracle an PostgreSQL)[1].  All without
worrying about threading...

But...

What happens when multiple processes attempt to access the zame ZODB
Data.fs file?  Is it multi-process safe?  Thread safe?  How big are
the sections protected by the mutexes? (or more importantly how long
do they take to execute)?

Thanks,

-- cary

[1] m apache talking to n database backend process, m > n, might be
    even nicer in some cases.  Gotta write that PostgreSQL backend
    multiplexor someday.

I would add to this that Relationship objects, or rather the unnamed
sub-objects which actually hold the data for individual pairings, should
have properties in their own right.  A relationship (especially many-to-many
type) can have information associated with it which properly belongs to
neither of the related objects, such as 'advance amount' for an Author
relationship.

It isn't clear to me that Relationships is really the right way to do this,
but if someone wanted to code it I'm sure people would try it out.

I'm guessing that Steffen is using the "default" start script, which passes the
"-D" parameter to Zope -- it is therefore running in "debug mode", and writing
error messages to the console.  Backgrounding it will work, sort of, but will
leave Zope expecting to write to the controlling tty -- if it goes away (i.e.,
Steffen logs out), then Zope will die hard when trying to write to it.

A better fix is to edit the start script and remove the "-D" from the command
line.  Without the "-D", Zope will daemonize itself, and the backgrounding won't
be needed.

Message-ID: <4.2.0.58.20000317180935.00c97e80@195.60.12.162>

I'm trying to build up some variables from more than one form which are to 
be inserted into an SQL table. THe problem is that as soon as I call the 
second form the existing FORM variables in the REQUEST are lost. I've tried 
saving them in a SESSION variable using SQL Session (I can save them OK) 
but then of course I have to get them back into something which an SQL 
Method can understand. I'm stuck at this point.

Is there any way to pass the SESSION variable into an SQL Method ??

Or, if not, How do I get the values back from SESSION so that I can call an 
SQL Method ?

Many thanks in advance

No, it is not supposed to be in the list. Zope is not SSI, nor does it try
to be SSI compatable. Zope does have analogous variables, though. For
example, when I navigate to http://my.server.com/jeff/dumpRequest, I get:

  URL0 = http://my.server.com/jeff/dumpRequest
  URL1 = http://my.server.com/jeff
  URL2 = http://my.server.com

  BASE0 = http://my.server.com
  BASE1 = http://my.server.com
  BASE2 = http://my.server.com/jeff
  BASE3 = http://my.server.com/jeff/dumpRequest

  PATH_INFO = /jeff/dumpRequest
  PATH_TRANSLATED = /jeff/dumpRequest

Since I haven't done much with SSI in the past, I don't know which one is
similiar to REQUEST_URI. If I had to guess, I would say PATH_INFO is the
one you are looking for.

Try this:

<A
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80&dtml-PATH_INFO;;weblint">Link
Text</A>

or,

<A href="http://validator.w3.org/check?uri=&dtml-URL0;;weblint">Link
Text</A>

Obviously, the second is preferred, since it is both more clear and
requires less maintenance (the URL is not hardcoded, so if your server
changes from dnrdb.cbi.tamucc.edu to newserver.cbi.tamucc.edu, the code
would not require change.)

Hope this helps.

Zope is, it's default storage, FileStorage, is not.

Yes.

Well, that question can't really be answered.  First off, there is a
global python interpreter lock.  I don't really want to get into the
details here, but basicly only one thread of execution can be in the
interpreter at once.  This is a pretty major limitation in Python's most
popular implementation, CPython (which is what Zope is based on).

The interpreter will 'give up the lock' every N bytecodes or so, there
is some mechanism for you to control this.  Check the python site for
more details.

Your idea is not bad, as long as you use a Storage that is multi-process
safe like ZEO.  I'm not sure if having as many Zope instances as Apache
instances is necessarily a good idea, since Zope instances can become
huge, many times bigger than their Apache counterparts.  Given Apache's
nature to do lots of forking and pre-forking (yes, this can be
controlled) this might lead to immense memory requirements.

Besides the AUTHORIZED_USER field in the http header what else does zope use to identify
an http packet from a browser ?.  I am just wondering can I not masquerade as a user by setting 
the http header using httplib or some such utility ?. I have not seen any session ids in the REQUEST
variable which is supposed to contain all the variables in the browser request

Values like this that you are looking for come from the front end web
server.  Most web servers pass a number of these variables into the
environment of a program that they are executing (in this case, Zope). 
The specification of what variables gets passed and how is called Common
Gateway Interface (CGI).

REQUEST_URI is not part of the CGI/1.1 (the most recent) spec.  I
suspect you are used to programming in some sort of SSI environment
where REQUEST_URI exists as a convienience for programmers.  I do
believe I recall REQUEST_URI being a variable in Apache.  This
convienience does not exist for Zope because it is not a standard CGI
variable and Apache does not pass it to Zope or any other CGI program. 
There is, in fact, probably some other standard variable that does the
exact same thing as REQUEST_URI.

The list of standard variable can be found at:

Subject: [Zope] Odd AttributeError (__call__)
Message-ID: <38D294FE.357B2DA4@harlan.frohwitter.com>

I have three instances of Zope running on three different machines (all
dual PPro).  On the first two machines, a simple <a
href="otherfolder">Click here to move to the other folder</a> works just
fine to hyperlink to the index_html in the "otherfolder" folder. 
However, on the third machine (ironically the one that I want to deploy
to) the same hyperlink encounters the following error:


           
           Zope Error

           Zope has encountered an error while publishing this resource. 

           Error Type: AttributeError
           Error Value: __call__



In all three instances, the security is set up the same way on all
documents, images, and folders accessed.  Incidentally, the deploy
server and one of the working ones are running Zope 2.1.4.  The other
working one is running 2.1.3.  Does anyone have an idea what my problem
is?

Thanks in advance,

Ron

AUTHENTICATED_USER is an object created after a client authenticates, it
is not an http header nor is it derived from the Authentication header. 
The Authentication header contains a user id and base64 encoded password
that is used to authenticate the client.

I assume by 'packet' you mean request.  HTTP is stream based.

No.  You can authenticate yourself with such a client, but you must
still have a valid password.  You cannot just insert any old user id
into the Authentication header and expect Zope to believe you.  That
wouldn't exactly be very good security.

Message-ID: <613145F79272D211914B0020AFF6401914DE7D@gandalf.digicool.com>

Hi all,

Zope 2.1.5 has been released - you can download it from
the usual place on Zope.org:

http://www.zope.org/Products/Zope/2.1.5/


This release fixes two fairly important security issues 
that have recently come to our attention:

  o It was possible for a Zope user with a fair amount of Zope 
    zen and permission to create DTML documents and Folders
    to circumvent the security machinery within DTML in certain 
    situations, possibly giving the user the ability to use 
    resources that he wouldn't otherwise be able to access via 
    DTML.

  o It also came to our attention that the DTML code in 
    ZSQLMethod objects was not subject to the same security
    constraints as the DTML code in DTMLMethods and DTML 
    Documents.

The 2.1.5 release fixes both of these issues and we highly 
recommend that you upgrade, especially if you use Zope for 
sites that allow untrusted users to create Folders and DTML 
Documents or DTML Methods.

The release also includes a number of recent bug fixes, 
including the problem in TimeStamp objects that caused 
the bobobase_modification_time() of Zope objects to 
appear to be a day behind. Note that this release contains
two binary changes, so those running Zope from the source 
release will need to rebuild the Zope extensions after 
applying the update. The fixes are also available in CVS 
and binaries will need to be rebuilt after the update for 
those of you using CVS.

Note that with the 2.1.5 release we will also be releasing
"diff" updates as .tgz files that will let you easily 
upgrade an existing 2.1.x site. These updates are available 
for those currently using the 2.1.x source release or the
2.1.x binary releases for either solaris or linux (diff 
releases are not available for win32 for now).

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

As far as authorization goes, I've noticed that I get prompted for a
user-name/password only once during a session.  After you've been validated, it
appears zope does not prompt you again for that browser session.

The reason I'm concerned is that if I have to do maintenance on someone else's
web browser, how do I ensure that after I leave a person cannot use the back
button or history list to gain manager access to the site?  Do I have to exit
the browser when I'm done?

Daniel,

THis is a limitation of HTTP basic authentication and is not a
Zope-specific problem.

Either quit the browser before you leave or write a short dtml method:

<dtml-raise Unauthorized>
Logout
</dtml-raise>

and call it before you leave.  Note that you need to call it, then click
"OK", or you will still be logged in.

Actually Zope does prompt your client on every single request (that
requires authorization), it must, because HTTP is stateless.  Zope also
validates every single request.

This is a 'feature' of the HTTP Basic Authentication spec that says
browsers can cache auth information.  It is however often a lack that
browsers do not let you manually clear this cache.

Yes.  Or force the client to discard it's cached auth info with a
<dtml-raise Unauthorized></dtml-raise>.

Yes, you can nest dtml-in's and you pass the parameters to the SQL
method by explicitly invoking it as an expression, not just as a
name.  (It happens that I asked a very similar question of this list
recently, which is why I now know the answers.)  My example, stripped
down a bit, looks like

<dtml-var standard_html_header>
<dtml-in search_author size=50 start=query_start>
  ...
        <tr>
          <td class="center"><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
          <td><dtml-in expr="return_authors(seq=seq)">
                  <dtml-var name>;
              </dtml-in></td>
        </tr>
 ...
</dtml-in>

I hope this is enough to get you started.  Contact me directly if you
would like more explanation.

Yes. Assuming that you're using basic HTTP authentication, restarting the
browser will clear everything out.

The key to figuring this behavior out is understanding how ZPublisher maps
a URL:

 * Split the URI path into a sequence of names

 * From the root, traverse each named object in order (allowing
   it to intercept the traversal, if it wants).  Traversal requires at
   least minimal permissions on the traversed-through object.

 * During traversal, allow the acquisition machinery to operate

 * If the last item traversed to is callable, call it;  otherwise, render
   it.

This works somewhat like permissions on a Unix directory:  you have to have the
executable bit set in order to traverse the directory, and the read bit set in
order to list it.

Hope this helps!

 Thanks.  I would think then this password is succeptible to the same pitfalls
as  sending clear text passwords over  the network which can be stolen. In
which case making users to use https is a good idea ?

Yeah this is probably the best idea. Zope sits

Message-ID: <Pine.LNX.4.10.10003172246500.10594-100000@yoni.northernwastes.org>

So...

I'm sure the answer to this question is painfully obvious, but I've
pounded on the docs and I can't find it for the life of me.

I have created a subclass as per the instuctions in the Zope Developers
Guide.  I am doing this specificly to avoid my inner class polluting the
global product list.  (There will ulimately be a large number of these
inner classes if I can figure this out.)

So far, so good.  Using the dtml-var tag I can display any property of any
instance of my newly created subclass.  But I also need to build a table
that iterates though all instances of this subclass and displays several
of it's properties.

I suspect this involves the use of the dtml-in tag, but I can't for the
life of me figure out what the syntax should look like.  The discussion of
dtml-in tag seems to imply a list of objects in a folder, and what I have
is a list of subobjects in an object.

Hints anyone?  How-To?  FAQ?


TIA,


Geoffrey L. Wright

When Zen borders on Kamikaze.....

DTML Document --> product method --> DTML method

I've been banging my head against this for 4 days in a row now. I want 
to call a DTML method, via a product method, from a DTML document, but
I don't succeed in setting the client namespace for the DTML method to 
the original DTML Document's namespace.

I'd appreciate any help!

I have a DTML document. It has a valid aq_parent. From this DTML document, 
I'm calling a product method, passing the DTML documents's aq_parent as
an argument:

<dtml-var "NFGnavCore.aqqy(aq_parent)">

This method has access to the aq_parent object all right, tested
OK. Next, the DTML method is called from the product python method and
the original aq_parent object is given as the new acquisition context:

	def aqqy(self, context=None):
		""" some test method"""
		retval= "Hi! I'm the aqqy method, called with context.id <b>%s</b>" % context.id
		return retval + self.aqqy_helper(client=context)

The DTML method 'aqqy_helper' is called all right, but has no access
to the context object passed in. Any attempt to access objects that
should be in the acquired namespace, for example:

		 My aq_parent id= <dtml-var "aq_parent.id">

results in an error message:

          You are not authorized to access aq_parent. 

Which, if I'm not mistaken, is caused by the validate routine called 
from OFS/DTMLMethod.py as documented in 'oldvalidate()':

        if inst is parent:
            raise 'Unauthorized', (
                'You are not authorized to access <em>%s</em>.' % name)

So what am I doing wrong, and what is the right way to call DTML
methods from product methods?

Well, this gives you the ability to create, for example, 'Car' and
'Bicycle' objects, and designate them both as meta type 'vehicle', then
create an 'Owner' relationship between 'vehicle's and 'Person's. A
trivial example, to be sure.

I suppose the relationship objects could be 'instrumented' to allow
other types of filtering criteria. Whatever the criteria though, the
possible objects need to be presented through a 'relationships' form
within the ZClass instance.

You're right, one-to-one relationships should be implemented as well,
but as you noted, this proposal is not as critical to implementing
one-to-one relationships as it is for many-to-many.

That's pretty close. My proposal actually has two levels of indirection:
first the relationship objects that are relevant to the ZClass are
obtained from a ZCatalog like object (the relationship folder in the
control panel), and then those relationship objects (themselves
ZCatalog-like) are queried to obtain the objects that the ZClass
instance is associated with. Then you should be able to access these
objects' properties and contents as if they were contained within the
current object's relationship:

<dtml-in Author>
<dtml-var name>
</dtml-in>

By doing it this way, you can add relationship types between you classes
as your application grows in complexity without having to re-instantiate
all your objects. All you would have to change would be the add/edit
methods in the ZClass, and whatever viewing methods that you want to
expose the new information (other than the relationships tab in the
management intrface).

Neither approach would give me the ability to refer to linked to objects
as if they were sub-objects. This is critical for the simplicity of the
DTML to access the associated objects' contents and properties. In
short, I want a pseudo sub-object that acts as a proxy for the real
object, not a symlink I can follow or resolve to access. The end result
is much the same, but the semantics are radically simpler with my
proposal. Note: associated objects should NOT appear within the
'Contents' tab.

First, relationship_aware is optional; all it's absence means is that
the object is not aware of it's outgoing relationships. Other
relationship_aware objects could refer to it with no problem. Second,
if, for example,  you want a relationship_aware Folder, just subclass
Folder and relationship_aware in a new ZCLass.

Zope doesn't know how to call or execute php code.  To do this, you need
to have Zope make an 'external' http call back out to Apache, which will
execute the php code, return it to Zope, which returns it to your
client.

Here is a good how-to on it:

Hmm. This update has broken all my zsqlmethods I've tested so far.  I've
reverting to 2.1.4.

Eg when testing from the management interface:

File D:\zope2\lib\python\Shared\DC\ZRDB\DA.py, line 459, in __call__
    (Object: sqlShowComment)
TypeError: too many arguments; expected 4, got 5

SQLSESSION has also died with this version release.

I couldn't find 2.1.4 on zope.org, but had a copy of 2.1.3, and that has
fixed all my zsqlmethods now.  Win32.

Hi everyone,

I'm using Amos's RSSChannel prodcut along with XMLDocument, but it seems
that upgrading to 2.1.5 has broken it. Can anyone else verify this?

Can you describe how it is broken?  Is there a traceback?  Are both
RSSChannel and XMLDocument broken?

Notice that line where it refers to RSSChannel.py. It's pointing to the
RSSChannel.py file in my previous (2.1.4) version of Zope. Odd.

However, it might have something to do with the fact that when I installed
2.1.5 I didn't untar a fresh copy of RSSChannel, but copied it to the new
directory instead. I did that because I'd made some changes to
RSSChannel.py and another file and didn't want to redo them. I did a 'cp
-a' if memory serves.

I was under the impression that you could copy the directories in
lib/python/Products/ over to a new Zope. Obviously it didn't work in this
case.

I think integer division was covered last week on this
mailing list.  Change 1/24 to 1.0/24 (the upshot is 1/24 is
evaluating to 0).

Fabrice,

I ran into similar errors.  Here's the response from Jo Meder that helped me
get MySQLDA compiled:

I suppose line 1125 of mySQLmodule.c is something like:

	tf = & (mysql_fetch_field_direct(self->res,j));

If this is the case, try applying the following patch to your
MySQLmodule.c (this is strictly "works for me"):

Subject: [Zope] Looking up object instances in a folder
Message-ID: <38D4C514.ED1D3EB5@funcom.com>

I have some instances of my own ZClass in a folder, and I can iterate
over them using:

<dtml-in "somefolder.subfolder.objectValues()">
  <dtml-var title>
</dtml>

The instances are stored using auto generated ids (simple numbers).

In addition to being able to iterate over the instances in the folder, I
also need to access an instance directly by using its id which is passed
in the REQUEST object, but so far I have been unsuccessful. What I am
trying to do is something like:

<dtml-in "somefolder.subfolder.getInstance(REQUEST.id)">
  <dtml-var title>
</dtml-in>

but I have not been able to get access to just the one instance (but
iterating works fine as mentioned before). Could somebody with a clue
give me a hint?

Thanks in advance,

   The ZMySQLDA is used (and will be used) by so many people that this
information should be packed into a HOW-TO and published along with the
very DA.

Subject: [Zope] Find object in a directory question
Message-ID: <20000319141420.A2559@mimar.demon.nl>

Hi,

I've created a ZClass 'CLink', which contains a URL, title and such things.
In my dtml-pages, I can do <dtml-var slashdot>, and the slashdot-clink
object will insert the <a href=...></a> stuff for me. I've got this 
working using the Renderable class. 

I've planned to put all CLink objects in the /links folder so I can
automatically create 'bookmarks' out of the links I reference to. I also
want to be able to categorize the links into subfolders, so I want to have
a links.sports.ski.resorts directory with ski resorts, and a
links.news.nerdish folder for nerd-related news. 
I can use <dtml-var links.news.nerdish.slashdot> to refer to the slashdot
object that way. 

However, I want to easily change my categories, without changing all
<dtml-var ...> that reference object in the categories. So I figured, I'd
make it <dtml-var links.find('slashdot')>. This should one day be the same as
<dtml-var links.news.slashdot> and the next day the same as
<dtml-var links.news.nerdish.slashdot>. With my external method (which only
looks in the current folder so far), I can't get this to work. 

Any ideas? Would the same be easier or simpler using a ZCatalog? 
Refering to a link should not be too much typing. 

As an extra question: is it possible to refer to an object in multiple
places, like softlinks (or hardlinks) in unix? Suppose I have a folder with
'My Frequent internet-visits', and 'News', they could both contain the same
CLink. Is that possible in zope?

Well, hope I made anysense..
Thanks,
    Chris Niekel

test linux installations later.
   I have problems upgrading to 2.1.5 - initially Zope came up well, but
when I tried to install 3rd-party modules (including SiteAccess) - I could
not login. I didn't traced the problem to SiteAccess or other product yet...

Hi,

Any recommendations for a good Python book? I found 'Learning Python 
- Help for Programmers', 'Python Essential Reference', 'Programming 
Python' to name a few.

Any suggestions?

Thanks!

Jonathan

Hello!

   Five minutes experiment - and the problem is narrowed down to
SiteAccess. Clean and fresh install of Zope 2.1.5, than some 3rd-party
modules - Zope came up well. install SiteAccess - and I cannot login to
Zope. Authentication failed all the time. Seems SiteAccess became
incompatible with latest Zope. Go back to 2.1.3, waiting for new Zopes
and/or new SiteAccess' :)

Hi,

may be some people might remeber my question concerning the user folder
question. Well, I haven't got any answer yet. But I found a source a knowledge
that would give me all the information. Basically I don't need much more then
the register DTML method of zope.org. Is the DTML source for the user
registration and user updates available for download somewhere? When I hit the
view "DTML Source" link I get a "Not Found" error. Everything else on Zope.org
can be inspected this way, but why not these pages? This can't be such a
security problem at all. Or am I just to dumb to discover the trick.

Thanks for any hint.

Best regards,

   These pages probably written in Python, hence there is no view_source
for them.

Subject: [Zope] Property Sheet access from Python Products
Message-ID: <200003191153560734.0E5EF386@iqtinc.com>

I am creating a product in Python and I want to use property sheets. I am able to add sheets and add properties to those sheets. However how I have to access the property sheets differently than if I was accessing property sheets on a ZClass programmatically. I suspect that I am perhaps not using the right mixin classes.

For instance, I have a property sheet 'Private' with an attribute 'prop1'
If I create this in a ZClass, I can use 
<dtml-var prop1> to access my attribute.
in my class I have to do the following
<dtml-var "propertysheets.get('Private').getProperty('prop1')"><p>

likewise in Python code I must access the attribute using 
self.propertysheets.get('Private').getProperty('prop1')
where in a ZClass I could do 
propertysheets.Private.prop1

My class declaration is as follows mixins:
class base(ObjectManager,PropertyManager, 
    Acquisition.Implicit,
    Persistence.Persistent,
    RoleManager):

Am I missing a mixin somewhere? Or do I have to access the attributes differently from a Python Class?

Thanks 
Bob

Could you give us some more detail?

First of all, and this was probably just a typo on your part, but the two
products will appear in the "Available Objects selection list", not in an
"External Methods" list.

If they don't appear there (after restarting Zope), go to the Control Panel
and click on Product Management at the bottom of the page. If the installs
of Squishdot and TinyTables are busted you'll see them listed as such on
this Product Management page. Click on each broken item and send what it
presents you with to this list. Someone will be able to help with it at that
point. What I've just described is the procedure for debugging a failed
Squishdot install per it's installation instructions.

And you do see a folder for each of these products in your
zope/lib/python/products dir, right?

Hello all,

I think I have Zope running. I can get to the localhost:8080/manage page
and go into the Control Panel and External Methods.  I've tried to
install TinyTable and Squishdot by untarring them in /var/zope with
subdirectories preserved. No go -- they don't seem to show up in
External Methods as they say they should by the Squishdot Install guide.
Can anyone help?

Ahh, thank you. The Squishdot documentation is quite non-specific and says
you'll find it in Available Options.  The first Available Options I found was
under External. I see them now and have created a Squishdot site selecting the
demo.  Not sure how to get to the first page of the demo which I've put at
localhost.  Can you tell I'm new? -- IV

Python Essential Reference before it went to print and it is also an

I saw the same problem under 2.1.2.  What was even odder, I deleted my
equivalent of NewTestVersion, and recreated it.  After entering the
version, my browser still said 'working in TestVersion'.  Restarting
the browser fixed that, so it must have been some sort of caching

Message-ID: <003601bf91e9$0c1d5680$265eb5cf@kevin>

I've built an application with ZOPE and would like to create a Java
interface to it (probably using jpython/wxWindows)

Here's how it should work:

When changes are made on the ZOPE site by a client, a notification is sent
from ZOPE to the Java interface and displayed in real-time. The idea here is
not to have a continually refreshing Java window, but a window which updates
only when it receives a message from the site to do so.

What I don't know is how to send the data from ZOPE to the Java client.  Can
anyone point me to any existing ZOPE Products/Projects/How-To's which are
similar to what I've described, or perhaps point me in the right direction?

This is because Zope has challenged for a username/password, and KFM doesn't
handle that nicely.

Either put http://user:password@localhost:8080/manage (iirc - there is a HOWTO
about this) or use a more sophisticated browser, like Netscape (but beware the
memory leaks when editing textareas. ):

David,

In order to use the management screens, you need to use a browser that
supports HTTP basic authentication.  To my knowledge, KFM does not
support this.  Use Netscape or Mozilla.

Hmmm.  Tried that, but still no luck.  Zope give me a
NameError, and tells me method is trying to reference a
nonexistent variable (fullname).  Here's the current
draft of my code:

<table>
  <tr>
    <th>Name</th>
    <th>Description</th>
  </tr>
  <dtml-with bwlib_abilities>
    <dtml-in "fullname('AbilityClass')">
      <tr>
        <td><dtml-var fullname></td>
        <td><dtml-var description></td>
      </tr>
    </dtml-in>
  </dtml-with>
</table>

Where bwlib_abilities is the name my container class,
AbilityClass is the subclass in question, fullname is
the sorting criterea and a poperty of AbilityClass, and
description is also a property of that subclass.

I know I'm hanging on something silly here, but I can't
for the life of myself figure out what it might be.

Also (as a more general sort of question):

Is this way of organizing data (ie, a bunch 'o
subclasses in a container class) a reasonable way to
deal with lists (50 to 100 items) of quasi-dynamic
objects?  I'm from more of a more traditional database
background, and am used to putting this sort of info in
a table.  But in the case of this particular app, ZODB
seems idea since it provides several less technical
users of the app a ready-made interface to these objects
and I don't really need access to this data outside of
this single app.  But there seems like an almost
daunting amount of flexibility in the way I might
organize this data -- objects in folders, subobjects in
container objects, zcatalogs, etc.

Thanks,

That behavior is expected. As far as I remeber, KFM (in the 1.x versions) 
does not support HTTP authentication. 
Furthermore, 
http://localhost:8080/manage?__ac_user=superuser&__ac_password=PASSWORD did 
not work for me either.

I don't know how KDE 2.0' new konquerer will handle it. But as much as they 
worked on this application, it will work there. Can anyone confirm that?

Regards,
Stephan

sha is an optional python module.  Presumably it wasn't included
in Modules/Setup when you compiled your python, or wasn't included in
the binary set if you got a binary distrabution.  (It should
be a dynamically loaded module).

The module is used if you request sha encryption on the password.
If you choose some other encryption type the sha routines won't
get called.  So as a quick fix you could remove the sha from
the import line.  But you probably really want to recompile python
to make sure that all modules Zope uses are included.  Hopefully
there's a list somewhere, though I can't recally seeing one...I just
enabled all the modules I could <grin>.

Message-ID: <Pine.BSI.3.96.1000319220658.3933H-100000@twirl.bitdance.com>

There was a recent mention of using Lynx to access the management
interface of Zope.  I'd like to use w3m.  It produces a more pleasing
page given all those little spacer images Zope uses.  Also, it
automatically launches vi for me when I hit return on the edit
screen's text input area, which is *way* cool <grin>.

However, it doesn't seem to be handling the management interface
correctly.  If I descend into a management link, I get the 'view'
panel for the link instead of the manage_main screen.  Worse,
I tried to 'rename' an index_html method, and it renamed the
index_html in the *parent* folder!  This is most weird.  Anyone
know what Zope could be emitting that w3m is not handling correctly?
I'd guess redirects, but I'm surprised I end up in the view screen
in that case...

I'm currently running w3m beta-991203.  Anyone know if whatever-it-is
is fixed in a later version, assuming there is one?

This is w3m's fault, it does not send the Authentication header to
frames in a frameset, just to the frameset.  Zope calculates
'manage_workspace' based on various factors, including whether or not
you are authorized to access the managment view.  Since you are
effectivly 'anonymous' in the frame it shows you the anonymous view. 
Uncheck 'View' for anonymous and you will probably get a 401
Unauthorized.

I don't think it's Zope's fault.  In this case, w3m is probably ignoring
or not understanding the <base> tag.

You are either not using the right python, or you are using an old
python.  Python 1.5.2, including the python that comes with Zope,  comes
standard with the sha module.

It's now a standard module as of 1.5.2.  I presume matt is using an old
python or turned off sha.

i got the setup running on rh6.1, running userdb (cookie auth) for
authentication, run start as root.  i've chmod -R nobody.nobody * in Zope.  i
copied my previous Data.fs to replace the Data.fs that comes with
Zope-2.1.5-src.  will this be the cause?  i've been upgrading this way since
2.1.0
i did run with -D, but saw no error.

I knew it was all w3m's fault, since it all works in other browsers <grin>.

Thanks for letting me know what the likely problems are.  Whether or
not I'll have time to do anything with the information remains to be
seen.  I wonder, though...I'm starting from the manage_main URL,
not the manage URL, so the page I'm starting from doesn't have
a frameset as far as I can see.  Descending into a folder works,
but descending into, say, a DTML_method gets me the view.  Well,
I'll have to just ignore the whole thing for now.  w3m is a nice
browser, I hope they get these bugs worked out soon.

I do still find w3m useful, though.  Since it's U command to go
to a new URL does accept relative specifications, it's pretty
easy to use that to descend into the 'manage_main' view of
the items I'm interested in.

I can confirm this, SiteAccess broke my 2.1.5 installation.  Oleg, if
you want 2.1.4 I can email it to you.

Zopistas and MikeP,

I'm trying to use etcUserFolder, and I want it to actually authenticate
off of /etc/shadow. saying /etc/shadow as the Password File doesn't
work, presumably because Zope is running as nobody.  Is there any way I
can let just etcUserFolder run as shadow?

On a similar note, am I doing something terribly stupid/compromising
here?

You can just use File objects to store the flash content, and refer to the 
objects from HTML the same way you would from a static HTML site.

I wrote a special Python object for it, inheriting from File, just so it 
would take care of its own HTML tag, just like the Image object does. 
This because the site in question contained quite a lot of different Flash 
objects, and the widths and heights changed sometimes during the course of 
the design. The designers just had to upload their flash content into these  objects, which they very quickly got the hang of.

However, for the one Shockwave game in the site, I just had the Shickwave developer upload to a File object, and the HTML for it was handcoded into the reffering HTML page.

No, that is the best way. Note that you don't have to give that user a password, and that for users from the specified set of IP addresses the authentication will be transparent.

when I was cataloging my zope site and was editing i did get a conflict
'competing' writes, which reminded me: how many times does ZOPE try to write
to the ZODB and then 'fails' and roll's back - is it 3? assuming this size
is configurable where would I go and change this?  when i was cataloging i
got this:

'\000\000\000\000\000\000\350\217' <- this happens right before the
competing writes. could someone explain what this \xxx\yyy\zzz is?

and how do I redirect ZServer's console to a file?  I'm in DOS right now
(havent done this in awhile) - and tried to "C:\Program

that didnt work..  In linux I've tried redirectings stderr and stdout to a

I believe that is python's octal representation of an internal object
index.  The 'could not load state' means the ZODB tried to load
the object from disk storage and could not complete the operation.

I'm getting those on my own database and haven't yet had the time
to track down where they are coming from.  I fear some sort of
database corruption, but so far the system has continued to function
despite these errors.

And I can't get it to work at all.  etcUserFolder.py says to put a file
in a directory called etcUsers in the root zope folder.  OK, I made a
folder zope/etcUsers/, and copied my /etc/shadow to there.  Then I
edited it to just have a few names:passwords.  then I chowned nobody. 
This wasn't working.  I copied it to the directory of the product-
lib/python/Products/etcUserFolder.
No juice.  while from crypt import crypt worked on the command line, I
still copied cryptmodule.so to my zope directory.  No dice.  So I copied
it to etc's directory.  No juice.

etcUserFolder still tells me there are no users whatsoever. what am I
doing wrong?

Yeh, and now that ZSQLMethods don't work neither does GUF with MySQL - e.g.,
the following code fails:

  <dtml-in "sqlGetUserRoles(username=username)">
  <dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'].rolename)">
  </dtml-in>
  <dtml-return ret>

With the error message:

  "You are not authorised to access 'rolename'"

The method has a Proxy role with appropriate access to the MySQL method.  It
just doesn't seem able to access the results variable!?

   Thanks! But I have it, and I didn't remove 2.1.3 directories while

I'm getting the same error on Zope 2.1.5. My zclass A which inherits object
manager. Inside it I have zclass B. When I try to create B object inside A
folder Zope gives me an Attribute Error: _getOb inside
B.createInObjectManager ()
It seems then Zope does not see class A's parent object manager. But, I have
exported A objects containing B object from 2.1.4 to 2.1.5 and that works.

There are no problems on 2.1.4. Classes are first defined on 2.1.4 an then
exported to 2.1.5.

Zope is built from source on RH 6.0, python 1.5.2

Hi,

  I've tried to write one generic SQL method and
passing argument to my SQL method using dtml-let but I
got KeyError. I've tried it with dtml-with also but
same thing. 

In my page I use:

<dtml-let curpage=total>
  <dtml-call hitinsert>
</dtml-let>

and MySQL method is:

update zp_stat 
set <dtml-var curpage>  = <dtml-var curpage> + 1

What I want to do, is passing mySQL argument and 
using one method. Ex:

<dtml-let curpage=astro>
	<dtml-call hitinsert>
</dtml-let>

total and astro are INT in my SQL table.

I dont know if dtml-let is a right way?

Any suggestion to do this?

Thank's

You can't, unless Zope runs as root (which would be a very bad thing).
This is by design.

The best you can do is:
    1) Setup Zope to run as its own user (eg. user 'zope') instead of
       user 'nobody'
    2) Add a crontab job to copy the /etc/shadow file to where Zope
       can see it, changing ownership to user zope and removing group
       and other permissions.

If you run Zope as the nobody user, then the encrypted passwords will
need to be visible to this user, as well as any other processes that
run as user nobody which is not a good thing.

Message-ID: <4.2.0.58.20000320110253.00a07c50@192.168.0.2>

Hello,


I upgraded to Zope 2.1.5 (Win 32) Saturday and carried out changes in the 
database (eg. created new ZClasses, added ZClass instances, etc.)

I had a nasty system crash (Win 95) around midnight Saturday. When I 
reopened Zope I realised the database was back to its 16:22 status:
- All new objects had vanished.
- The last transaction logged in the Undo list is dated about 16:22.
- The very Data.fs in the filesystem is stamped 16:22 if you can believe it.

I checked the Z2.log and it shows these missing changes. So I didn't dreamt 
doing them.

I suppose these changes are lost?


Cheers.

This makes the shadow password suite worthless.
Assuming readonly access to /etc/shadow it's better to use a simple 
wrapper program that can do the access. This program should be carefully 
designed to not allow arbitrary input to compromise security.

One example is checkpassword (not for non-root programs) which is located 
at http://cr.yp.to/checkpwd.html
It's designed primarily to get a simple interface to various 
authentication schemes, but my be used as an example.

method" that creates HTML-table based boxes on the screen that can be maximized
and minimized, like the ones on some of the big web portals.

My first simple try with just using Folders, two methods, and properties,
worked quite well.

I created a method that looks up whether the box is minimized or
maximized and renders it respectively. The box itself is a (currently empty)
folder that has a property "max" that can be "show" or "hide" (could also be
boolean, but I'm thinking of other states like "just show headlines").

The content would then be rendered by other methods that are called in a
"content" method by the "box" method. Using those boxes on the site
curently looks like this (for a folder "news_box" containing the content):

<dtml-with news_box>
   <dtml-var box>
</dtml-with> 

The problem I could not solve with my very limited Zope knowledge is how to
"switch" the boxes from minimized to maximized et vice versa.

In other words, I'd need a DTML expression that I can put into a method that is
called by a hyperlink on the "minimize/maximize" button to switch the
property state and then returns the site again.

The two problems are:

How can I set a property in DTML (REQUEST.set won't work as far as I can see
it)? Namespaces could be quite tricky with that.

Where should one put the method to update the property status? The tricky thing
is that after the update the site from where the request came has to be
re-rendered!

I know I could switch to cookies or SQL-based stuff. But that wouldn't make the
solution flexible for use with Zope objects.

Am I on the right path? If the whole thing doesn't work out that way I could
try using my own tree tag version that renders a box instead of the "+"/"-"
stuff). Doesn't sound that easy.

Thanks a lot for suggestions!

Hi! 

I thought I'd forward this to the list in case it helps anyone else:

If you want to use FTP with SiteAccess then you'll need to add the following to SiteRoot.py, after
line 124 (at the end of the SiteRoot class), and at a similar place in AccessRule.py:

    def get_size(self):
        '''Make FTP happy'''
        return 0

If anyone knows WHY this makes it work, please let us all know! :-)

cheers,

Chris

Read the documentation at www.zope.org. I think the best is to start with 
the feature tour and then "Zope Content Manager's Guide".

Is this really what you want to do?  Under this scheme, user 1 views the
site, clicks on the maxamize box, and gets the rerendered page.  Now
user 2 visits the site, and sees the maximized box.  He doesn't want
that one, so he minimizes the box.  Now user 1 clicks to maximize some
other box, and suddenly his previously maximized box is minimized.

Or am I missing something about your design?

In any case, changing properties in this way to store state is going to
cause your ZODB to grow quickly as each property state change is stored
as a new, undoable, transaction.

It seems to me you want to use either some sort of Session product to
retain the state, or do what I suspect the tree product does and
put the state you need to set/save into the URL using argument
passing ("?xxx=yyy") or by using forms to submit the change requests
and storing the state in 'hidden' fields in the frorm.

Your need a list of the AbilityClass instances in 'bwlib_abilities',
which you can sort by fullname. Assuming 'AbilityClass' is the meta-type
of your subclass, try something like the following: 

<dtml-with bwlib_abilities>
     <dtml-in "objectValues('AbilityClass')" sort=fullname>
       <tr>
         <td><dtml-var fullname></td>
         <td><dtml-var description></td>
      </tr>
     </dtml-in>
</dtml-with>

Subject: [Zope] mimetools -- an example, I hope this helps
Message-ID: <H0001bac0796f0b3@MHS>

I had to play around to get mime stuff to work right.  I needed to email
messages to about 1500 people.  Every person reaceived a couple of documents
that were the same, and each person received one document that was unique for
that individual.  I also through in a timer loop to provide a one minute delay
between each email message.  (Our mail server could not handle the load.)  I am
enclosing the code that worked for me.  Of course ymmv :)


pull_contacts : this is an sql method which pulls user information out of an
Access database.  Most of the variables listed come out of this database.

dtml-log : I used the logger product to create some logs so that I could see
that my mail messages went out.  I don't think this worked the way I wanted it
to work.

mime tag :  I added some custom code to the mime stuff because the mime stuff
does not add the mime version 1.0 header.  This may not cause problems for
everyone else, but it does cause problems for HP OpenMail and Lotus Notes.  I
do not know if anyone has fixed this in the standard zope code, but it was not
working when I did this mailout.

"_[QUESTION].data" :  this was what I had to do to pull in the unique object
for each individual.  (I imported all of my documents into the zodb.)

that makes sense.

ok, this i don't get.  i'd have thought that since i opened
what i thought was my own instance of a Zope DB, using my own
FileStorage pointing to a file in /tmp:

	db = ZODB.DB( ZODB.FileStorage.FileStorage( '/tmp/foo.fs' ) )
	connection = db.open()
	root = connection.root()

that this would have nothing to do with the DB that Zope
was using for its internals.  all of the code examples i've
seen for ZODB are from python programs, and all include code like this.
if this *is* using Zope's internal DB instance, then that would imply 
that you can't use ZODB outside of Zope when Zope is running.
what am i missing?

> (why you are getting the

it appears that was unrelated.  i actually got my example to
work since posting.  the "unable to access" thing only happens
when i get an exception due to bugs in my code.

cool.  that's good to know.

indeed.  that's part of why i wanted to use a completely separate
database.  the other part is so i can use the same routines outside
of Zope, perhaps at the same time.

i'll try that.  thanks for your help.

thanks, i'll give that a try.  i don't really need a counter, at all.
it was just a minimal example to try and figure out ZODB.

That's very odd. I tried reproducing this and couldn't.

What do you mean by parent?  Presumably, A subclasses ObjectManager.
Right?

That's because export/import doesn't use createInObjectManager.
 
I suggest one of the following:

  - Try a very simple example that you can deacribe completely
    so you can explain it to me in complete detail and I can try to reporiduce
    it.

  - If your database isn't too big (or if you can reproduce this
    with a small database) send me the database. I'll look at it and see if I
    can see what's going on.

I'm not seeing this. What are you trying to add the ZClass to?
Zope 2.1.5 has a fix to ZClasses that makes it work correctly
with ObjectManagers, including ObjectManagers that don't use 
instance attributes to hold sub-objects.  All ObjectManagers should
implement a method, _getOb, that is used to get an object from the object
manager. If you are adding your instance to an object that is *not*
an object manager, then the above error would be expected.

Problem actually solved (by digging arount in how-tos). Some remarks:

Yes, I save the state of the boxes with their properties. Where else
should an object save its state? I mean, "state" IS a property of  the object.
In terms of object orientation, this seems to me to be a much more logical
design than to save session stuff in some non-zope external database or file.

O.k., my ZODB might grow, but is it really that much of a problem (I mean,
a problem that can not be solved by just packing the DB once in a while)? Any
experience with that out there?

The problem with concurrent users switching each other's boxes from one state
to the other only occurs if they use the same objects. What I use in my
implementation is seperate box objects in different user folders. Those objects
only contain stuff that is customized. All "heavy lifting" is done by methods
in the aqcuisition path, so that there is no real duplication of code even
though the complete box structure is duplicated. In a later stage, those objects
(currently just empty folders with a view properties ...) will become instances
of a class.

The cool thing about this is that the portal becomes extremely customizable.
You can add boxes only you can see, use different rendering methods,
style sheets, whatever can be put into a folderish object.

My idea is actually working quite well now. I'll try to make it a ZClass and
put it on the web. But first I want to do some testing.

As soon as I find the time for it, I'll put my ideas into a how-to.

Please disregard this. I didn't perform the test correctly.
I now can reproduce this. Stay tuned.

Message-ID: <38D64B95.99E1F5FA@sistelnet.es>

Hello everyone:

I have posted the second part (Use Cases) of the zope memepool project at
http://zope.sistelnet.es/memez

The final goal of this project is to have a completely functional
memepool-like application, product or whatever, built completely from
scratch, using Zope. The project tries to use a completle Object Oriented
approach to development, and (since I am no Zope guru) feeds from user
comments and recommendations.

Please have a look.

Sorry this update took so long, but this past month has been busy as heck.

Best regards.

Yes, what I didn't know about your design was that the objects in
question were specific to the user.  In that case, and if it is not
expected that the user will want to change his settings with every
session but instead this is a customization feature, then what you
have described sounds like an ideal application of Zope and its
object machinery.

I think it all depends on how frequent the updates are and how many
users you have.  If your site gets to be high enough traffic
and users make frequent enough changes for it to be a problem, you
could always switch to an undo-less backing store for the ZODB and
therefore not have to change your implementation to continue to
scale. Others with direct experience with portal-like sites may have
more useful input.

Are you, by the way, aware of the Portal Toolkit project?  I haven't
investigated it yet, but if you aren't following it it sounds like
something you'd be interested in.  I'm sure they are thinking about
scalability issues there.

I want to compare them has dates and not strings with the built-in cmp()

OK, so it's not my favourite editor but I thought I'd

Can anyone tell me what I should set EDITOR_CMD to?

'C:\WINNT\system32\notepad.exe' and 'C:\WINNT\system32\notepad.exe %s'
don't do the job. (What's the %s for anyway?)

The %s will be replaced by the filename. This so Notpad knows what file to 
edit.

You will have to double the bacvslahes for this to work, because in Python 
(as in many programming languages), the backslash has special meaning:

  'C:\\WINNT\\system32\\notepad.exe %s'
 
or, you could place an 'r' in front of the string (r stands for raw):

  r'C:\WINNT\system32\notepad.exe %s'

ZopeEDIT will open Notepad for you. When done, you save and close notepad. ZopeEDIT will ask you wether or not you want to save the file to Zope. Click 'Yes', and your changes are now on your Zope server.

Subject: [Zope] dtml-let and MySQL
In-Reply-To: <20000320100802.14614.qmail@web4001.mail.yahoo.com>
Message-ID: <4.2.0.58.20000320162316.00ca5100@195.60.12.162>

As I understand it any variables you set in <dtml-let> </dtml_let> blocks 
are local to that block of code. There's no way to 'pass' them to an SQL 
Method. SQL Methods only use values which have been set within the REQUEST 
variable. The REQUEST variable is where Form variables are held - but Form 
variables only exist until the next Form is called. You can however 
explicitly force values into REQUEST using the syntax

<dtml-call expr="REQUEST.set('yourvariable','yourvalue')">

and these would then be available to an SQL Method.

A tip which I found very useful when working with the REQUEST variable and 
forms is to put the following line into your code
<dtml-var REQUEST>.

This displays all the current values within the REQUEST variable.

There's also a useful How-To on Namespaces which gives more background on 
this area (search for Namespace in www.zope.org).

However IMHO its an area of Zope that needs a lot more documentation and 
tutorials because I don't think it's very intuitive.

I also think it would be nice to have a version of SQL method which allowed 
you to pass the values you want into it - it's beyond me at the moment though.

Good luck

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985DC@pces.cadlab.it>

[Absolute beginner's question...]

I'm thinking to use Zope for an Internet site I have to develop for an
internal client. They will just receive a PC Box from me and will know
nothing about the technology in it.

I wonder if I can safely allow them to drop HTML documents inside Zope. This
would allow to publish their own simple HTML documents without worring about
DTML and the like (I do not think they are interested in developing their
own DTML-enabled sites...).

Is it Zope able to handle plain HTML+CSS+JavaScript documents, without
having to use any DTML file?

Can the user just drop a HTML document in a server directory and have this
document published on the intranet? How can I determine the directory they
can use?

Thanks.

        1. play with the imap settings (probably need to change the
           LS* variable in IMAPHACK.py, can't recall it's exact name)
        2. make sure you are running 1.0.4 (a fairly recent version).

Sure.  Although with a little work you can have it automatically get your
intranet's headers and footers, for example.  But just plunking it in works
just fine.

Give them a user that only has permission to access a certain folder.  Then
set up ftp for them and they'll never know it's Zope.

Not exactly, but close enough.  A DTML Document could certainly
contain just HTML code and no DTML, and Zope would happily return
it and the client would render it just as if (say) Apache had
returned it.  I presume you could use the ftp server built in to
Zserver to upload the documents to whatever folders you had given
them permission on.  But keep in mind that all the Zope data is
stored in the ZODB (a single file in the unix filesystem) not as
seperate files in that filesystem, so any update transactions need
to go through Zserver somehow or another in order to update the content.

You might want to consider teaching them the (pretty easy) management
interface, though, as they could use that to upload files directly
from their PC desktops using just their web browser.  Who knows,
they might even decide they want to start taking advantage of Zope's
content management features, and actually start learning DTML <grin>.

Zopists,

Are there any other quoting methods besides html_quote and url_quote?  I
am looking for something that turns periods and minus signs to an
alternative as well.  I guess I could roll my own external method, but
I'd rather not if there are more to choose from.

Doh**2. That now works very nicely. Thanks. One last request:

Any way of suppressing the reflection of the password in the

Message-ID: <Pine.OSF.4.02.10003201131530.4100-100000@batman.tamucc.edu>

Currently, I have a customized standard html header, and would like to be
able to use the same header for all files, but have different titles for
each...I have tried using this in my header:

<title><dtml-let var="'TITLE'"></dtml-let></title>

and then using this in the individual file:

<dtml-let var="'TITLE'" 
value="'My title'"">
</dtml-let>

I only use the "'....'"...becuase otherwise, I get syntax
errors.....however, when I look at the source code on the page, it reads
<title></title>...so apparently this is not working.  Any suggestions?

Thanks,

This is the second report of this bug but I cannot reproduce this, can

You can't.  As security policy, we do not write code that lets Zope open
files outside of the Zope directory.  You can, of course, do this in
your own code, but we do not recommend it.  My first version of
etcUserFolder actually was able to open files anywhere (hence the name)
but I was enlightened by Jim that this is a possible secuirty hazzard.

There error occours because there are pickles in your database that
cannot be loaded.  The 'persistent' information for an object in the
database is a 'pickle', or a serialized representation of the object. 
In order for the object be loaded into memory the pickle needs to be
unwound into an object in memory.

However, this serialized representation does *not* contain any active
code, it's just the state of the object.  In order for the object to
truely 'come to life' the pickle must be matched up with the python code
that all objects have in one way or another.

This error occours when the pickle can be read, but no coresponding
python code could be matched up with the object to bring it to life, or,
an error occoured while object was being unpickled.  Unfortunatly, there
aren't any better iagnostic tools to find why these pickles cannot be
unloaded, and for the most part they are now orphaned objects, you
cannot delete them or manage them or remove them from your database.

I can envision some kind of tool like fsck or scandisk that goes through
your database (probably offline) and lets you examine/purge/fix these
kinds of dead objects.  Ty Sarna has come up with an introspectio ntool
called the Tranalyser that would probably be a good place to start.

from DateTime import DateTime

Now you can instantiate DateTime objects like so:

DateTime(string)

and compare them easily:

if date1 < date2:
  print 'foo'

Hi,

I just wanted to let you know that this has been fixed in the zope 2.1.4-3
package; never, never, never release a package without having it installed
yourself once, I know ;-)

Thanks for the report,

Message-ID: <Pine.LNX.4.10.10003201247220.564-100000@lawlearn.wuacc.edu>

I'm trying to create several screens to allow my technician to keep a log
of problem reports.

I chose to create a search form.  The data will display in the usual table
form and the user will select the item wanted for display in an update
form with the values shown as default field values.

In the table view, I created a link to my next form in the following way:

<a
href="http://localhost:8080/School/Admin/Computer/displayitem?id=<dtml-var
id>&Submit=Submit&Query">

The problem is that no data gets stuffed into the values="" attributes of
the form which leads me to believe that either I'm not using the
<dtml-sqlvar> tags correctly or I'm not calling the data selected from the
database (mysql) for use in the new form correctly.

I read the how-to on inserting sql data, but I want to create a form that
will update existing records.

Any help will be appreciated,
Joe

Thanks.  One problem that arises when I do this, is that in my
webpage, when I do  "view source" I have ...


stuff
<title></title>           ---> From the standard_html_header file
stuff

<title>mytitle</title>    ---> From the file itself

I guess I am wanting to know how to tell the header to place the correct
title in its own <title></title> portion, and not to add a second
<title></title> line.

Thanks,
Jessica

Subject: [Zope] ExtensionClass
Message-ID: <FRQFOV$I2ZLh74u5vUUBGyDxD3ExLIi5oGV5zoaH@uol.com.ar>

Hi!

I have an ExtensionClass(es) question and, being the 
latest releases of them distributed with Zope, I 
decided to ask it here.

Situation:

1) Class A subclasses 2+ extension classes E = 
{E1,...,En} and perhaps another non extension classes C 
= {C1,...,Cm}. That is, class A(B1,...,Bk): ...., where 
B1,...,Bk are each in E or in C.
2) a is an instance of A (a = A())
3) a.foo(bar) is invoked
4) getattr is invoked in the first extension class in 
the inherited classes list (i.e. the first Bi belonging 
to E)

Question:

What happens then?
I guess that calling Py_FindMethod (inside getattr 
implementation) will trigger a search in instance and 
base classes' dictionaries, but what about the other 
extension base classes and what about the searching 
order?
I can't find any doc on these, so I'm needing your help.

Thank you, Carlos.

(Snip.)

This is due to a fix in Acquisition to a bug that obscured a bug
in the handling of inner ZClasses. Sigh.

We'll be putting ot a release to fix this. In the mean time, if you wish
you can edit lib/python/App/Factory.py and change the line:

    _setObject=Acquisition.Acquired

to:

    _setObject=_getOb=Acquisition.Acquired

You are exactly right!  I took out the title lines in the file, and just
kept the title line in the header, and gave my file a title...and voila!
Thanks!

Yes.

Actually, there is a buglet in XMLDocument that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

In 2.1.5, when you add an XML document, you get a
WrongDocumentException.  This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py.

There may be other problems, however, I'm not very familiar 
with XMLDocument and wouldn't be a good person to find them.

Perhaps you could apply this patch and see if you can find 
anything else wrong.  If you do, please provide me and Amos 
with some sample data and instructions for reproducing the problem.

It did work.  The filename that appears in the traceback is the name
of the .py file when it was compiled to produce a .pyc file.
Since you copied the pyc file, the old name was retained.

Please see my other note for information on a fix to this problem.

It looks like you are trying to use an anchor tag to submit a form. 
This will not work as it is not proper HTML.  You need to use an <input
type=submit...> or some other valid way of submiting the form.

Hi,

sofar I solved the creation process of user accounts. This was quite easy
after I read the code for this. But now I have problems adding new roles via a
specialized interface. I setup tghe REQUEST object correctly, then I call
manage_defined_roles and I get various errors. Is their any method at all to
create Roles besides the management interface of Zope or via External Methods?
Setting local roles is easy, but I can get the role added to the system at
all. Any help appreciated. Thanks a lot.

After reading the how-to that Kevin Dangoor and making some changes from
the management interface, I am able to edit values connected to my Zope
objects. While this is a start, it really isn't ideal. As Nick Henderson
suggested, it would be better if there was a way to do this from standard
DTHML, so that the editing form looks like a filled-in entry form? Does
anyone have any suggestions? Also, a number of the fields in my entries
are coming from "select" lists or checkboxes. This is being done to
control the vocabulary so everyone enters the same term for the same item
(eg. It would be a problem for my application if person #1 calls it "Time"
and person #2 calls it "Time Magazine." Does anyone know of a way to take
the existing values of an entry and pull it into a select list and tell
the list to keep them "selected," or have an idea of a direction to go
in order to attempt this?

There's actually three parts to every error, the error type and
description, and the traceback.  Could you also send the error
description (it's above the traceback) so that I can look at the code
and they to see  what is raising the TypeError (which is the error
type).

What kind of errors?

You should be able to call a method that adds roles just like the
managment interface does.  Have you checked out
lib/python/AccessControl/access.dtml?  At the bottom is a second form
that lets you add roles.

Michel,

I'm trying to use a link on the Report Form to call another form that
displays the single database record with each field filling in the new 
form.  If the user is the proper authenticated user, an update button will
be available, anonymous will only get a listing of the record.

Granted, I'm not doing it the right way. Perhaps my question is how do you
select a value, in this case the record number, and use that value as a
key to pass the entire record to the form for display.  My calling DTML
Method is listed below.

So the question is how can I call up my new form with my selection
appearing as data.

Thanks,
Joe

Message-ID: <4.2.0.58.20000320194209.01654a20@192.168.0.2>

Hello,


I got a similar error with Zope 2.1.5 on Win32 Saturday. Here's how:

- I created a ZClass, TestClassA (it subclassed ObjectManager).
- In TestClassA, I created another ZClass, TestClassB (it also subclassed 
ObjectManager).

So I got ControlPanel / Products / AProduct / TestClassA / TestClassB.

Then :
- I created a TestClassA instance somewhere.
- In this instance, I tried to create a TestClassB instance.

I got:
Error Type: AttributeError
Error Value: _getOb

Somehow this was related to RESPONSE. This error didn't occur when for 
testing I added ", RESPONSE" to the line

   <dtml-with "TestClassB.createInObjectManager(REQUEST['id'], REQUEST)">

in the "TestClassB_add" constructor method.


Cheers.

Alexandre

I'd really like to see a global method that replicates the property sheet
editor but is callable from code rather than the management interface
and can thus be "wrapped"...

There is some sample code somewhere that shows how to mostly do
this in DTML.  I looked at it, but wound up just creating my own
specific editing form anyway, because I couldn't get it to run
out of the box and didn't have time (or at that point the knowledge)
to debug it.

Here's a snippet of code from my custom edit form that does this for
a multiple select property I have.  Hopefully this will help you roll
your own.  'regions' is a lines property defined on another propertysheet
(named 'constants' <wry grin>).  I haven't yet figured out how
to call this variable so I can use it in the addForm.)  I basically
copied this out of that sample code I mentioned above.

  <tr>
    <th><label id=in_regions>In Regions</label></th>
    <td>
      <select name="in_regions:list" multiple size="7">
        <dtml-in regions>
          <option <dtml-if
            "_['sequence-item'] in in_regions">SELECTED</dtml-if
          >> <dtml-var sequence-item></option>
        </dtml-in>
      </select>
    </td>
  </tr>

Actually, i need to access to sequences at the same time. That's not

The '%s' gets replaced by a temporary file name, it definitly needs to
be there. I know nothing about notepad.exe, but it sounds like notepad
can't accept filename arguments on the command line. I can't verify this
however. I know people are using ZopeEDIT in Win?? so it must be
something with notepad.

Hi Oliver - would you expand a little bit on how you "solved the creation
process of user accounts?"

Thank you.

Brian,

It appears to be a good fix.  I'll run with it and let you know how it goes.  I suppose that I should  cc the list as well.

Hi Curtis -

We are going to be releasing a fixed update today - in 
the meantime, if you could try something out to verify 
that it fixes your problem as well, that would be great.

I've attached a file ZRDB.tgz. If you copy that to your
lib/python/Shared/DC/ZRDB directory and unpack it, then 
restart Zope you should be working again. If you have a 
minute to try this can you let me know how it goes? 

Thanks!

Suppose that Bi belongs to E (following the previous 
names) and is not, for example, Persistent, and that Bj 
is Persistent (where j > i).
The problem of the getattr (I mean in Persistent) 
invoked only when the attribute being accessed doesn't 
belong to the instance dictionary or class dictionary 
is still here, isn't it?

Subject: [Zope] my zope has got no pid!
Message-ID: <000a01bf92a4$f172fd00$1cf108c3@SteffenLemke>

Hello there,

something's strange with my zope. I am running zope as my personal zope-user (at least I have started it this way) but I don't get any pid if I say "ps -a". And I cannot stop the server because the script tells me kill: xxxx - no such pid? What's wrong with it?? Is there any additional flag I have to set or unset in the standard-scripts? 

Thank you for your help,
Steffen

Ok this problem is due to the bug in 2.1.5 that also breaks ZSQL
Methods, it is unlrelated to ODBC.  We will be releasing a 2.1.6 that
fixes the problems in 2.1.5 including this one.

try 'ps aux' (on linux at least).  Any other platform, who knows.

I don't know.

No, but certainly your Zope is running with a PID, it must be.  Go to
the control panel, you should absolutly get the right pid there.

Here is what I did to get it going...

EDITOR_CMD = ' "notepad" %s' 

# I put a space in there just to make it easy to see for the email but by
quoting notepad the command line gets interpreted properly.

Message-ID: <613145F79272D211914B0020AFF6401914DE8B@gandalf.digicool.com>

Hi all,

Zope 2.1.6 has been released - you can download it from
Zope.org:

http://www.zope.org/Products/Zope/2.1.6/


This release fixes a few issues with Friday's 2.1.5 security
update release:

  o Some bits from the currently development branch got into
    the 2.1.x release branch, causing problems for folks using 
    certain database adapters - this has been fixed.

  o A fix to Acquisition that happened in 2.1.5 caused a problem
    with ZClasses, since some of the code in Factory.py previously
    worked around the problem and now no longer needed to. This has
    been fixed in 2.1.6.

Users of the SiteAccess product should note that the security 
changes in 2.1.5 necessarily require a change to the SiteAccess
product - as he noted in a previous email to the zope list, Evan 
will be releasing an updated SiteAccess shortly.

Also, the XMLDocument product has a buglet that was made effective
by a fix to a bug in Acquisition.  Prior to 2.1.5, there were cases
where acquisition-wrapped objects sometimes didn't have their full
acquisition context.  This was fixed in 2.1.5.  Unfortunately, 
some applications may depend on the old incomplete wrapping. :(

Currently, when you add an XML document, you will get a
WrongDocumentException. This can be fixed by changing:

        if document and ownerDocument and document != ownerDocument:

to:

        if (document and ownerDocument and
            getattr(document,      'aq_base', document) is not
            getattr(ownerDocument, 'aq_base', ownerDocument)
            ):

in the appendChild method in class Node in file Node.py. A new 
rev of XMLDocument containing this fix will be available soon.

Note that we have also posted "diff" updates as .tgz files 
that will let you easily upgrade an existing 2.1.x site. 
These updates are available for those currently using the 
2.1.x source release or the 2.1.x binary releases for either 
solaris or linux.

To apply a differential update to your site:

  o download the appropriate .tgz file from zope.org
  o shutdown your Zope process
  o copy the .tgz to your Zope directory and extract it
  o run w_pcgi or wo_pcgi *if you are not using a binary release*
  o restart your process

In an NT cmd.exe shell:

  ...2>C:\temp\zope.err >C:\temp\zope.log

or:

  ...2>&1 >C:\temp\zope.log

should both work.  On Win95/98, I think you're sunk -- the COMMAND.COM shell is
too brain-dead.  You might try 4DOS or another replacement shell.

"Broken pipe" says that the peer process/thread on the other end of a pipe died
without shutting down the pipe cleanly.  You should be concerned, because these
are your "Zope" threads that are dying -- eventually, you will have none left to
service requests.

This problem is a symptom of something inside Zope which is killing off threads,
most likely an unhandled exception somewhere.  Try turning on the
STUPID_DEBUGGER_LOG and see if you get more enlightening log output.

Hi,

well I use the following code snippet in my factory method of the product I am
developing.

<dtml-with "manage_clone(Home, REQUEST['new_id'], REQUEST)">
        <dtml-call "manage_changeProperties(
                        company_name=REQUEST['new_company_name'],
                        title='OS Job Tracking System für ' + REQUEST['new_company_name']
                    )">
        <dtml-call "acl_users.manage_users(submit='Add Role', REQUEST=REQUEST)">
        <dtml-call "manage_defined_roles(submit='Add Role', REQUEST=REQUEST)">
    </dtml-with>

I set the role element of my REQUEST object to a string, which is the name of
the new role. When I look a manage_defined_roles in
lib/python/AccessControl/Roles.py it searches for a submit element in the
REQUEST object that has a certain value. Otherwise it calls manage_access. 

Well, I set submit to the required value, so that _addRole is called. Then I
get the error

    Error Type: AttributeError
    Error Value: aq_acquire

And when I call it without setting the parameters at all

    Error Type: KeyError
    Error Value: SCRIPT_NAME

When I call it with REQUEST=REQUEST I get the first error again.

Any idea what is wrong with my call? I am not using any external method or so
from product, but I develop the product in Zope and use only DTML scripting,
cause this is sufficient for my task.

I am running Zope 2.1.4 as a standalon zserver. May be this helps too.

Any hint would be really fine.

Best regards,

    Oliver Andrich

Hi,

I just discovered something strange. At least I think that it is strange. I
can assign users Roles that don't exist at all in the system. In my last Email
I tried to create a Role in a system wide context. Well, know I removed the
role add code and just added the user with a fantasy role. Now the management
screen can't handle the user anymore cause the role doesn't exist. But when I
do a acl_users.getUser('admin').getRoles() I get the fantasy role I
    specified. Ok, this is not the solution, but should the manage_user code
    check if the role that is specified exists at all?

Bye, Oliver

start.bat is all you need.  It will leave a dos-box open, but that's fine.  It
will show you some (occasionally) useful output from Zope.

Once you have run it, take your handy web browser (NutScrape, or Internet

Steffen

This happens when you rename the Zope directory after installation.

The stop script has a hardcoded directory in it.

If you edit the stop script and change the old directory name to the new one
all works as expected.

Vladimir,

I just had this same thing happen, and bypassing the factory worked.
I changed the calling method from calling "maClass_factory to
myClass_addForm, and the add method worked fine.  That seems very buggy
to me.

The traceback was posted onthe zope-dev list this morning.

Here it is anyway:

<dtml-with "WorkDayClass.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-call "propertysheets.WorkDay_properties.manage_changeProperties(
             work_date=REQUEST['date'],

 <dtml-call reindex_object>
<dtml-with>

Now I get:

Error Type: AttributeError
            Error Value: _getOb

Subject: [Zope] Sybase: How generate id keys? (surrogate keys)
Message-ID: <20000320232355.87383.qmail@hotmail.com>

Hi,

How do people generate id keys (surrogate primary keys)
in Sybase+Zope? There are some recommended ways of doing it
in Sybase with stored procedures but I can't run stored
procedures in Sybase.

I am looking at heavy-traffic strategies. So I need something
slightly better than a simple increment table for the keys.

Any recommendations? Thanks in advance.

D'oh!  The environment variable which Zope checks for is STUPID_LOG_FILE:

 * If it is set to a blank string, Zope writes the verbose logging
   to stderr;

 * If it is a non-blank string, Zope opens it as a file and writes the
   verbose logging there;

 * Otherwise, Zope suppresses the verbose logging.

Ayup, there have been several threads reporting such restarts lately -- have you
been following them? (some were on the zope-dev list, I think).

Just to add my two cents:  I've seen these as well, usually connected to
someone disconnecting from downloading a page mid-way, usually also
connected to zope going into a really tight 'select (0,1), select (0,1,2),
select (0,1,2,3), select(0,1,2,3,4), etc loop - until it runs out of fd's
it's allowed to open, crashes, and needs restarting.  Oh, and only when
running with FastCGI.

My response so far has been to whack a while : ; do ... done loop around
the kickoff command in ./start, and run the whole lot under screen -dmS.
STUPID_LOG_FILE didn't produce anything that was immediately useful to me
:(

I've just upgraded to 2.1.6, and so far I haven't seen the problem, which
may or may not be a good sign ;)

Hello all,

I have the following code fragment in a method called
CategoryCustomizationForm contained in the folder /News:

<dtml-if preferences_saved>
  <hr>
  <b> Your preferences have been saved </b>
  <hr>
  <dtml-call "manage_changeProperties(preferences_saved=0)">
</dtml-if>

where "preferences_saved" is a property of the folder /News.

In the folder /News, the security view verfies that the permission of
"Manage properties" is allowed only by those in the "Manager" role. In
order to allow all authenticated users to use
the "manage_changeProperties" method in "CategoryCustomizationForm", I
assigned the proxy role of "Manager" to "CategoryCustomizationForm".
However, zope still only allows users in the role of Manager to access
"manage_changeProperties" in my form. In other words, the proxy role
assigned to the method "CategoryCustomizationForm" failed to override
the permissions of its containing folder /News. As a temporary fix, I
gave the "Authenticated" role permission to "Manage properties" in
/News. This works with regards to allowing all authenticated users to
access "manage_changeProperties" in my form. However, in the long run, I
don't want all authenticated users having manager type access to all
properties of /News. I have this failure of proxy roles in other areas
of development too, such as dtml creation of folders via manage_clone.
Is there something I'm missing about how to use proxy roles? Thanks for
your time.

Unfortunately the IDENTITY column is not a good option.

According to our local Sybase expert, The IDENTITY columns
are just too buggy to use, even after the newer releases of
Sybase. They cause too many troubles, that is why we are
looking at alternatives. In older versions of Sybase, the
problems were so severe that they would cause the database
server to crash. Some drawbacks that were mentioned:
(some are fixed, but these are not the only problems...)

(1) When database server crashes, apparently the IDENTITY
    column jumps to the next block of values, so the table
    index space become sparsely populated, and you may hit
    the roll-over situation earlier than expected.

(2) When using BCP utility to download and upload tables,
    there are some problems with the IDENTITY columns, too.

(3) It is hard to access the values of the IDENTITY column
    when you are in multiple SQL statements.

Anyway, there seem to be too many problems, so the IDENTITY
column approach has been discarded. :(

regards,

Hung Jung

I've released LocalFS v0.1.7. It hasn't been tested extensively so I've left the
bits for v0.1.6 up on the site. I'm just too excited to wait. :)

The url is: http://www.zope.org/Members/jfarr/Products/LocalFS

Enhancements in v0.1.7:

- Added the ability to customize mappings between file extension, content-type,
and Zope object class.
- Added the ability to customize content-type to icon mappings.
- LocalFS objects now work with the <dtml-tree> tag, so they can be traversed
using the navigation menu.

(plus a few bug fixes)

If you try it out please let me know what you think or if you find any problems.

Thanks,
-jfarr

Subject: [Zope] ZClasses and clone/delete methods
Message-ID: <14550.61379.392791.186258@antares.int.plain.co.nz>

I need to know whether I can set up clone and delete methods in a
Zclass that automatically get invoked any time someone deletes or
copies an instance of that class from the management interface (via
cut and paste or whatever). 

What I'm doing is creating a simple link class that just stores the
key to a RDBMS row that contains all the details of the link
(description, URL, clickthrus etc). The trouble is that when a link is 
deleted from Zope, it needs to touch the db record or that record will 
become orphaned - ideally the db record needs to keep a reference
count of the number of link objects out their, and they need to
increment or decrement that count as they get copied and deleted.

So can this be done with a ZClass (if not, why not :-)) and if it
can't, how can I do this with a Python Product (given that I've never
written one!).

TIA,
John.

Message-ID: <38D6F845.A010DBE2@suprize.com>

Hi,

    I have Zope 2.1.5 and Oracle 8.0.5 running on the same Linux box.
ZOracleDA was installed successfully and bridged Zope and Oracle.
I can call my stored procedure by creating Z SQL Method like:

    begin
    procName(arg1, arg2,...);
    end;

But I cannot get return arguments (OUT args) no matter how the Z SQL
Method is set. I have tried the interfaces mentioned in DCOracle
documents, but failed. The only work-around I've found is creating 
extenal methods and import DCOracle via python. Is there any way
to get the OUT arguments from Z SQL Method? Thanks a lot!

I've read
http://www.zope.org/Members/Zen/howto/FormVariableTypes
and a few other HOW-TO's and still haven't figured out
how to make use of the :record type in form variables.

My form looks like:
<form method="post" action="processForm">
<input type=text name=choice.1:record>
<input type=text name=choice.3:record>
<input type=text name=choice.10:record>
<input type=submit>
</form>

Now processForm need to tell which and how many choice.x:record are entered.
This works:
	<dtml-var "REQUEST['choice']">
that's as far as I can go. I want to do:
	<dtml-in "REQUEST['choice'].keys()">
		<dtml-var sequence-item>:<dtml-var sequence-value>
	</dtml>
but it doesn't know what "keys()" is.

Question: how do I get the keys and values for this "choice" record in
processForm?

Thanx,

iI'm going to have to disappoint you.

- I never published the object, it was simple and not that general. Also, I cannot release it now, because it was written while working for my previous employer.

- The site for which I used it was for a big Dutch youth event, and now that it has taken place the site has been taken down again.

Record objects do not implement a mapping interface.  Form elements are
turned into attributes of your 'choice' object, so your objects has
instance attributes named 1, 3, and 10.  You will need to use
_.getattr() to access these attributes since numbers are not very good
attribute names.

It might be a good idea to look into a new ZPublisher type called
:dictionary (or :mapping) that works much like :record, it would be
fairly trivial to implement, want to take a stab at it?

Subject: [Zope] ZODB Couldn't load state - help please
Message-ID: <38D73050.8A2546B8@knoll-is.de>

Hello Zopers,

I just joined these mailing lists. I have a boring problem I can't
understand. I wrote this little program:

import Persistence
import ZODB
import ZODB.Transaction
import ZODB.FileStorage

class dbclass(Persistence.Persistent):
	def __init__(self):
		self.thedata = 'testdata'

def getdata( request=None ):
	name = 'somename'
	db = ZODB.DB(ZODB.FileStorage.FileStorage('myfile.fs'))
	connection = db.open()
	root = connection.root()
	if not root.has_key( name ):
		print "initialising"
		root[name] = dbclass()
		get_transaction().commit()
	r = root[name].thedata
	connection.close()
	return r


This program works very well if it is started directly using the python
interpreter. But if I call it from Zope using 'Try it' in the management
console it works only one time. The second call of the function results
in:

Zope Error

          Zope has encountered an error while publishing this resource. 

          Error Type: AttributeError

Subject: [Zope] discussion/forum product/zclass
Message-ID: <00032116404602.04048@tokey.kedai.com.my>

hi all,
i've been looking at confera and zdiscussion as a possible forum solution. 
however, i'm also looking at other perl/php products.

my Q:
-anybody on the list have deployed confera/zdiscussion on  a large site?
-what will a lot of traffic do to Data.fs?  will i have to pack often?
-i'm looking at modifying zdiscussion to store to an RDBMS.  anybody done that
already?  if so, mind sharing how you did it?
-i'm not a python programmer.  and i would like to implement filtering for
certain words/malicious html tags.  i see an external method here.  any other
solution?  dtml maybe? :)

i thank all for your help, pointers, docs.

I had the same experience a few days ago with a 2.1.4 installation running
under Win98. I have a couple of different Zope instances running on Linux and
Windows, but that was the first data loss. It seemed to me as if the session
had been running in "demo" mode so that changes would not be really persistent.
As in Alexandre's case, I first thought I was dreaming because there was no
hint of my data except for the log files.

I suggest some further investigation into that. If Zope really lost things that
easily, I'd consider not using ZODB for production sites ...

BTW: In my case it also was a Windows system crash that caused the data loss.

This sounds like Win98 is using a write-cache that didn't get flushed to disk
because of the crah. IIRC, Zope forces write cache flushes, but it could well
be that Win98, being a client-patform, ignores that for performance reasons.

Then again, who'd use Win98 for production sites?

Try %1, instead.  %1, %2 etc stand for a commands first, second 
... positional parameter in the MSDOS/Windows/Windows NT

*Sigh* Did anyone read my reply to the original message?? A backslash has
special meaning in python! And positional parameters have nothing to do with
python either!

In python (as in many programming languages based on C) \n means newline. Just
fire up a python interpreter:

  >> repr('C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\012otepad.exe %s'

\012 is the octal representation for newline. Note that, as \W and \s are
meaningless, they are interpreted as if you used a double backslash.

The solution immediatly becomes clear:

  >> repr('C:\\WINNT\\system32\\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'
  >> repr(r'C:\WINNT\system32\notepad.exe %s')
  'C:\\WINNT\\system32\\notepad.exe %s'

ZopeEDIT uses the string to build up a command to feed to the system. It uses
the default python % operator to replace the %s (which is a C-sprintf-like
string formatting code) with the filename of the temporary file it creates.

Please, next time, use the python debugger or something to see what goes
wrong. Paul has long since gotten ZopeEDIT to work, BTW.

Subject: [Zope] Weird ZSQL Method thing...
Message-ID: <38D760E4.F25D1D00@nipltd.com>

Hi,

This is weird, I've got a solution but I don't know why I need to use it...

I have a DTML Document that uses two ZSQL Methods, something like:
<dtml-in item>
  ...the item ZSQL method returns cid...
 <dtml-var cid>
 <dtml-in case>
    ...the case ZSQL method takes cid as a required parameter
 </dtml-in>
</dtml-in>

Now, using this returns an error: Bad Request: [cid] 
which I've grown accustomed to seeing when a requried parameter is missing.
However, if I dtml-comment out the second dtml-in, it works fine and the correct cid is displayed by
the dtml-var.

The only way I can get it to work is to make the second dtml-in look like:
 <dtml-in case(cid=cid)>

I really don't understand why I need to do this and why the 'case' ZSQL method doesn't just pick up
cid from the current namespace...

Any ideas?

Chris

Um, more or less (apart from the quotes). The ZSQL Methods use namespace
different from than normal DTML documents/methods (though I don't
exactly know how). Therefore you have to call them explicitly with an
argument.

It would work too. The dtml-in variables are not available to sub-methods,

If this is true, it's really counterintuitive and should be changed if at all possible.

If it's specific to ZSQL methods or in otherwise confusing situations, then there's even more reason
to change it...

Anyone got any comments/suggestions?

Subject: [Zope] FSSession and external methods...
Message-ID: <v04220807b4fd1bb332c0@[128.240.198.13]>

Hi all,
Anyone got any experience with FSSession and external methods 
(actually a PythonMethod).

I want to get the data out of an FSSession object using this construct-type

<argument>self</argument>

FS = self.FSSession
out = ""
for k,v in FS.items():
     out = out + "K:%s, V:%s<br>" % (k,v)
return out

and get this;

<!--
  Error type:  AttributeError
  Error value: _v_data
  -->

Looking at FSSession.py, _v_data is there as part of the FSSession class;
     def items(self): return self._v_data.items()
but it's not getting through to the method.

Anyone got a fixe for this? I need to do some heavy processing with 
the contents of the FSSession object so I can't *really* use DTML.

TIA
tone.

have you given roles to the user???
to protect the folder, I suppose you have created a role 'ROLE', and said
that anyone but those with the role 'ROLE' are able to view the folder.
however, if the users in the NT User Folder are not given roles, there are
two case:

when you create a NT user folder, you have to choose whether default
behavior when a user is not given roles is to acquire user settings from
higher user folders or not.

- if default behavior is to acquire settings, due to the very nature of user
folders, NT User Folders says the user *does not* exists if no roles are
defined, to allow higher user folders to handle the user. this is the
default for a nt user folder created in a sub folder

- if default behavior is not to acquire settings, NT User Folder always says
'yes' when the user is asked, but if no roles are defined, the user is
assumed to have to anonymous role. this is the default for a nt user folder
created at the top level

if roles are created for a user, it always exists, what ever the default
behavior is.

back to your problem: if you choose not to acquire user roles, all users for
which you didn't give roles are *anonymous*, so they have no rights on your
protected folder.

good

nope but be careful about the above point

This is not true.

Method A:

<dtml-with "_(bob='uncle')">
  <dtml-var B>
</dtml-with>

Method B:

<dtml-var bob>

_will_ print 'uncle'.

It is specific to ZSQL Methods, they create their own fresh namespace. 
There may be a good reason, I can't think of one.

ZSQL Methods create their own namespace (I don't know why).  You must
explicitly pass them arguments.  You can, of course, pass then entire
namespace:

<dtml-in "case(ns=_)">
  ...
</dtml-in>


and in your SQL Method:

<dtml-with ns>
 ...
</dtml-with>

This is, like all of my advice, completely untested and off the top of
my head, but it should fly.

We have deployed a heavily modified Squishdot site that handles around
30-40K requests a day.

Depends. Trafic by itself does not increase the size of Data.fs.

Now but we will have to. After 3000-4000 postings Squishdot is very slow
and I suppose zdiscussions too.

An external method will be appropriate. Forget DTL for such task.

IMHO, this isn't true. I have several ZSQL methods which have named parameters. 
It appears that they can get these parameters from REQUEST and possibly (I can't remember and
haven't got time to check :( ) things like dtml-let and dtml-with without having to explicitly pass
them which is why I was so surprised that dtml-in didn't work as expected.

Can anyone who knows say why this is the case and exactly what the critera are for something being
'visible' to a ZSQL method's parameter list?

HSCH,

Chris

You need to call FSSession before you can use it, as in DTML otherwise the
data will not be loaded into _v_data. I have just tried the following and
it works:


FS=self.FSSession
FS()
out=""
for k,v in FS.items():
   out = out + "K:%s, V:%s<br>" % (k,v)
return out

Martijn, you're right. Nobody would use Win98 on production systems. But quite a
few people use it on their notebooks or home PCs for development, I guess. At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Well, I don't think that is the optimum solution, especially for big sites. 
Even though that is the Zope way of doing things, I hate the idea that I 
clutter my ZODB with files. I would suggest you add a property called 
attachments to your Class which points to various URLs and then serve the 
files via Apache. You may want to use PCGI to do this.
We just switched to PCGI and now we serve Images and Documents from another 
port via Apache (we can also use SSL now). That helps to keep the I/O 
stream to the ZODB file moderate. Remember, ZODB is just big one file (even 
though Zope does a lot of caching). You could also check into LocalFS, 
which is nice in some cases (even though we were unsuccessful to upload 
files, using it.)

Stephan

Subject: [Zope] Modifying Standard Error Pages
Message-ID: <Pine.LNX.3.96.1000321140832.11696D-100000@marvin.nipltd.com>

I'm currently trying to modify Zope's standard error pages in order to
have errors (such as 404 not founds or DTML errors) e-mailed to the 
webmaster as they occur.

At first, I thought this would be as simple as modifying the
standard_error_message document found in the root of the Zope
installation, but it appears that changes to the file do not get displayed
(even after forced refreshes) and thus it doesn't seem to be in use.

A search on zope.org lead me to find the real error message embedded in
<zopedir>/lib/python/OFS/Application.py - I've modified this and it
appears to work, but doesn't support HTTP related errors such as 404s.

After a bit of a search, I've tracked down HTTP-related error reports to
<zopedir>/lib/python/ZPublisher/HTTPResponse.py but, while this can be
modified, it doesn't support DTML as the HTML error message is returned
without apparently being parsed by Zope. As a result, I can't have
dtml-sendmail send an error message report.

Okay, I could modify HTTPResponse.py to send a mail using something like
Python's smtplib, but before I do that, have I overlooked the obvious and
is there really a much cleaner, easier way to modify the error pages
without delving into the sources?

Thanks in advance!

Neither. Add orphan=0 to the tag, and you'll feel sane again.

if ommitted, orphan is set to 3. This means that if the last batch is smaller
than 3 items, that batch is added to the one but last batch. See it as a
'minimal batch size' parameter.

When you call a method 'by name' (<dtml-var methodName>) then the DTML
machinery will magically try and line up any arguments to that method
with any names in the namespace.  It will do this for any kind of method
that accepts arguments, DTML Methods, SQL Method, ext methods,
PythonMethods, and methods written in python of the object this()
etc...  _However_ if that method is a SQL Method then as soon as you
enter the method any reference to <dtml-var name> in the SQL method will
NOT find the name in the previous DTML namespace.  If you want a name in
the DTML namespace to match an argument, that's a different matter all
together, and it will work, if you want to <dtml-var name> in a SQL
Method and 'name' is in the namespace of a calling DTML method, then it
won't work.

Have a look at:

  http://www.zope.org/standard_error_message/view_source

and you'll see how the Zope.org site handles 404 Not Found.

In the current CVS they do.  Tanming, if you're using a source code
distribution of Zope you can change the definition of class 'record' in
ZPublisher/HTTPRequest.py to the following:

class record:
    def __getattr__(self, key, default=None):
        if key in ('get', 'keys', 'items', 'values', 'copy', 'has_key'):
            return getattr(self.__dict__, key)
        raise AttributeError, key

    def __getitem__(self, key):
        return self.__dict__[key]

    def __str__(self):
        L1 = self.__dict__.items()
        L1.sort()
        return join(map(lambda item: "%s: %s" %item, L1), ", ")

    __repr__ = __str__

Cheers,

Evan @ digicool & 4-am

Are these batches of records the 'last' batch in the ZSQL query?
If so, it's the 'orphan' parameter kicking in, which *I believe* is set to 3.

If you have 19 records returned with a batch of 4, you get
1-4, 5-8,9-12,13-16,17-19 - no problem there

If you have 9 records returned with a batch of 4, you *would get*
1-4, 5-8, 9 (on it's own).

The 'orphan' parameter would make the last batch return 5-9 (ie 5 records).

It's described in greater detail in the ZSQL users guide...

As many of you have noted the FastCGI site has been down since last week.
Sorry about the hassle, there were significant hardware problems.

The site is now in the process of being moved.  Until the domain
transfer is complete you can reach the new site here: http://209.212.66.147.

The mailing lists, fastcgi-announce and fastcgi-developers, have been moved
as well along with the existing list membership.

Posting to the list won't work until the domain transfer is complete:
mailto:fastcgi-developers@fastcgi.com.

The domain transfer should be complete in the next couple of days.  I'll
send another email when its complete.

Please let me know if you have any questions or problems.

Neither.  The in tag by default does not like orphans (result batches
smaller than 'size').  Set 'orphan=0' and sleep in peace that your
sanity is intact (and that the in tag is bug free).

Here's something that worked for me, it's got extraneous imports and 
stuff ('cos it's the front end of something bigger), but it does 
work. I add nnn_ to the beginning of file names so I can have more 
than one file called 'test.doc' in the directory, and I've not 
finished the URL stuff yet, but it certainly uploads normal files to 
LocalFS (probably because it bypasses the LocalFS machinery all 
together ? :) .

add_details is a ZSQL method that adds info about the upload into a database.

Martijn,

I think the problem is that any changes made to standard_error_message don't appear to have any
effect. I've tried just simply changing the text, add ' - wibble' after 'Zope Error' and the old
error message is still displayed, even after restarting Zope...

What's going on?

Is there some method such like with SiteAccess that you have to 'set' a DTML method as the standard
error message or is something else causing the old error message to be displayed?

HYCH,

Chris

I have no idea. I don't use SiteAccess, so I don't know what influence it has
on this issue. I can change standard_error_message just fine here. Try and
understand what the default code does first, then try and make a few
educated-guess changes to that code.

Does anything show up in the undo log? After a change, does the edit window
have a message 'Content changed [Date]' just below the tabs?

You've seen this before?  Great you're the first person who actually
gives me hope I'm not insane.  We have been running 7 sites from a
single zope install replicated across 3 servers.  Two of the servers
experience frequent Zope restarts (as often as every hour).  The third
server running an older version of Redhat (6.0 I believe) and
glibc-2.0.7-29, and hardly ever restarts.  

We are running Redhat 6.1, glibc from rpm glibc-2.1.1.6, python from rpm
python-1.5.2-7 and Apache/1.3.9 mod_fastcgi/2.2.3 and Apache/1.3.11
mod_fastcgi/2.2.3.

We have even gone as far as to modify FCGIServer.py to produce "debug"
output  to determine which requests go unanswered at the point of
restart; hoping this would lead to some suspect DTML or ExternalMethod
code.  No luck.

We're waiting a bit to upgrade to see how it shakes out w/ SiteAccess
etc.

We've also recently bumped cache *WAY* up, 450,000 items, w/ 5 minute
target max between accesses.  Which has resulted in 200M of memory for
the process.  This appears to have lowered the number of restarts, but
not eliminated them.

In your experience with this problem have you noticed /manage and or
traffic volume to have any impact on the frequency of restarts?  We've
been looking everywhere to determine what may be going wrong, and have
experienced the most restarts when traffic and /manage volumes are up. 
We unfortunatly have our most /manage volume within the same timespan as
our heaviest traffic.

Hopefully we can find a solution to this.  Thanks for the feedback.  Let
me know if you make any headway.

Hello,

I still can't figure out why my DTML document gives me the following
Zope error :

    Zope Error

    Zope has encountered an error while publishing this resource. 

    Error Type: AttributeError
    Error Value: __call__


when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?


Thanks in advance,
Greeting,
Eric

This is what happens when an exception is raised while rendering
standard_error_message (obtained through acquisition).

ZPublisher renders the default standard_error_message, rather than let
a problem go unreported.

Hi,

As I found out - you can not index numbers and therefore not search 
for dates using the zCatalog.

But I was wondering 'bout workarounds. I thougt maybe if I could 
change the bobo_modification_date to one of my own. That I could 
search for. But that seems like a pretty crappy workaround...

Ideas.... anyone ???

Has anyone modified the Zope index method to also index numbers ??

I think that's probably wrong. The thread-safety-ness of MySQLdb is that
two threads can share the module. You can't safely share connections, but
this is more of a MySQL limitation than a MySQLdb limitation. Of course,
you can share connections if you wrap a mutex around it so that only one
thread uses it at a time, but it is far better to have multiple
connections: Each connection is a seperate MySQL thread on the server
side.

The old MySQLmodule was probably thread-safe, but not thread-friendly: If
you ran a blocking operation (like a query), it would block all the
threads (i.e. it did not give up the Python interpreter lock during
blocking calls). This apparently causes really bad performance with Zope.

I may be deficient on Zope zen, but it seems like you would definitely
want to have several connection objects around, perhaps one for each ZSQL
Method, so that these can all work in parallel. From a security
perspective (i.e. you aren't just paranoid, you know they are out to get
you), this may make sense, as you can set up seperate users in MySQL with
very specific privileges, so each connection object can only do one thing
and can't be hijacked for something else.

Yup, just discovered this myself. :-) I put a buggy dtml expression in the
document and Zope displays a default message rather than the custom one
I've generated - removing the buggy stuff brings the custom version.

Thanks to Martin for pointing me to the 404 handling on zope.org, I've
solved the initial problem I was having with getting changes recognised in
the standard_error_message in Zope's root, and now have it mailing a basic
error report to the webmaster.

There are a few issues Chris noticed when he was doing some stuff, but I'm
going to take a look at these further before posting more on the subject.


Cheers,

John

Have you looked at the Zope.org error message and played with that? You should
be able to do a RESPONSE.redirect I think.

Martijn,

Yeah I look and even copied the code and fixed it to work on my server but
doing a redirect doesn't seem to work.  At best I get a blank page with no
redirect taking place.

Oh well, I'll keep on experimenting.

See ya

You may want to look at Pavlos Christoforous' FSSession or Anthony
Baxter's SQLSession products to make this happen.  Look on zope.org.

Not a problem. Use ZSQL Sessions and an update SQL statement have it fed in
from a Zope form. Do a little error checking and Bob's Your Uncle.

I don't think this is true. Catalog does not index numbers in TextIndexes,
but I think a FieldIndex would work fine. I'm pretty sure I've done it (with
dates, even), but not 100% sure.

Just make sure you use a FieldIndex, and I think you'll be fine.

Hi,

    Take a look at the FSSession and SQLSession products. They allow you to
store data on the server for each user, and I think it would be pretty easy
to implement a shopping cart that way.

Hi,

  I went thru mailing list but I did not find a
response to my problem.

I've written simple form with one text field and one
file type:

<form action="/content/result" method="post"   
ENCTYPE="multipart/form-data">
<input name="c_title" width=30 value=""> 
<input type="file" name="c_body:file" width=30>
<input type="SUBMIT" name="SUBMIT" value="Submit">
</form>


result method is:
....
<dtml-call "manage_upload(REQUEST['c_body'].read())">
<dtml-var REQUEST>
....

When I press Submit button I get

Error Type: NameError
Error Value: manage_upload

Any suggestion?

b) How can I simply affiche (if I find a PB) the
upload content in browser?

c) How can insert uploaded content in MySql. I Have to
use:

VALUES
(
'<dtml-var c_title>',
'<dtml-call
"manage_upload(REQUEST['c_body'].read())">'
)

It works? it seems bizarre?

Thank's

The REQUEST object is defined in ../lib/python/ZPublisher/BaseRequest.py. I
don't see a delete there, but by studying that code, I'm sure you could
easily implement one.

Subject: [Zope] newbie CGI question
Message-ID: <Pine.OSF.4.02.10003211327080.9449-100000@batman.tamucc.edu>

I currently have a site that uses numerous perl cgi scripts....I have
successfully managed to transfer all the static pages to Zope...however,
what about CGI scripts?  Does Zope support them?  Can I use the Zserver
with these scripts or should I use the other server (with Apache)?

Also, from the Zope experts out there, I need your opinion.  I am
considering using Zope for my existing web site (it's fairly large)
...however, I would still like to continue to use perl/cgi, (have a
lot of time invested in my already existing scripts), and not use much
Python (no flames please...haha).  I like the graphical capabilities of
Zope, and the ability to assign roles to  certain users...but I don't know
if this is worth switching, especially if I am going to continue to use
perl/cgi (if that's even possible)...any suggestions out there?

Thanks in Advance,
Jessica

It seems to me that all this would require is passing the "_" namespace in place
of the REQUEST when calling the ZSQLMethod -- am I missing something?  Values
found in the REQUEST would still be found, but would be overridden by any
intermediate namespaces (e.g., from dtml-in, dtml-with, or dtml-let).

[RH] REQUEST is a python dictionary, but probably one that DC has altered
for security (or other sound reasons). I once used REQUEST.clear(), which
flushes the whole REQUEST  (this was necessary because I wanted to do a
batch operation on a fileobject of 500K , but didn't want to pass it around
several times). This worked, I believe (but I never tested this through).

Martijn, you're right. Nobody would use Win98 on production systems. But
quite a
few people use it on their notebooks or home PCs for development, I guess.
At
least that is what I do.

If your assumption that a Windows cache problem is the reason for the data
loss, is right, that would mean that Win98 must be holding the whole DATA.FS
in
memory/virtual memory without saving for hours!

In that case it might be a good idea to warn everybody to shutdown and
restart
Zope under Windows 9x after major changes.

BTW: So far, I've never lost data when I just "killed" the Zope process. So
Windows seems to save data at least in that case ...

Joachim.

[RH]Hm, I have been developing for quite some time on an feeblish win95
machine at home, which repeatedly crashed, but I have never ever lost
committed transactions. Strange.

Message-ID: <003501bf9376$b97ec460$0100a8c0@pinol1.sfba.home.com>

I've used Z Search Interface to create a set of forms and reports. I renamed
some of the objects, including the data source. I've corrected all of the
values that are visible via the Zope management interface so that the new
names are reflected. All of the queries run by independantly if tested.

But none of the reports (search results) operate if they are run via the Z
Search interface pages (they did before the renaming ops). The error
returned is:

Zope Error
Zope has encountered an error while publishing this resource.
Resource not found
Additionally, there is one Z Search Interface "form" that will not open at
all, even if *all* of it's text is stripped out. At that point, to the
"naked eye", there is no content to the method at all. I was expecting to
find some hidden properties associated with the objects that I could tweak
and fix these errors but no luck.

What is hidden from me that I cannot access? Or is this evidence of some
corruption in the ZODB? And are these "oddities" (as they appear to me now)
peculiar to the Z Search Interface or is this common behavior with Zope in
general?

    Zope has encountered an error while publishing this resource.

    Error Type: AttributeError

when I ask Zope to view it as the document is in a sub-folder, but
viewable without problem when the document is in the root folder.


Any rational explanation ?
A link to the revelant paragraph in the documentation ?

[RH]Can you send us more detailed information:
the exact dtml for the local and the subobject method and the traceback of
the error (you can get it by viewing the source of the error page)

The REQUEST object stores form data in its .form member, which is a Python
dictionary.  You will need to find a way to execute the statement, "del
REQUEST.form[ 'variableToErase' ]", or the equivalent expression, "delattr(
REQUEST.form, 'variableToErase' )", neither of which can be done from DTML or
from PythonMethods (ergo, must be done in an ExternalMethod or done from a
Python product).

Subject: [Zope] Installation Directory Problems in a W2K install
Message-ID: <PKEBIHPBEGMAPMNHFPCFGEGNCKAA.jlv@volition.org>

Hi.

I installed Zope 2.1.6 on a W2K machine and have one problem installing
additional components.

I have tried to install TinyTable, Squishdot, Photo, ZPhoto-Album, and
others but NONE of them get noticed by Zope when re-starting the service.

A clue, I believe, is in this error message when trying to "import"
ZPhotoAlbum.zexp:

---
Zope Error
Zope has encountered an error while publishing this resource.

Error Type: Bad Request
Error Value: File does not exist:
C:\PROGRA~1\ZOPE-S~1\import\ZPhotoAlbum.zexp
---

Shouldn't that directory be:

C:\PROGRA~1\ZOPE-S~1\inst\import\ZPhotoAlbum.zexp

???

None of the lib installations that would be in ..\inst\lib get noticed upon
restart, which leads me to think that somewhere in the installation it
doesn't have the "installation" setting correct.

Thanks.

Jason

I always thought the inst directory was used by Zopeat install time and only
then.

Any products should go into <zopedir>/lib/python/Products

Any zexp files hould be in <zopedir>/import

You shouldn't need to put anything in the inst directory.

I'm pretty convinced it's related to glibc version - the fact that a strace
of the process shows it repeatedly opening/selecting over more and more
fd's just before the process goes away suggests some sort of funky error
handling to me - maybe one of the socket handling routines had a change in
what error it produces between glibc versions?  Anyway, I haven't had time
to sit down and properly dig.

2.1.6 suffers the same problem.

I can reproduce it instantly with a large enough page - stop the request
mid-way, the closing of the socket to the client while Zope is serving the
page up seems to be what causes it to go into it's loop, then die.

Mondo apologies to the zope crew for not putting this in the collector - I
had hoped to find the actual problem (and maybe a solution) first, but ran
out of time :(

Sometimes you do, sometimes you don't. I know that sometimes I can acquire ZSQL
method parameters from the request. Sometimes I have to provide them explicitly.
I haven't been able to figure out what the rules are, either. If anyone out

Ok,  I finally did it.  I got my boss to slip a nice little application
server in the budget.  So here I am trying to spec out a nice Zope server.  
 
What should my priorities be when building this beast,  I think we'll be
able to spend about $10 Grand on this beast.  We will be running a secure
site using Apache and OpenSSL,  and we are targeting about 100 continuous
concurrent users.  I have already set SOME priorities, because uptime is a
big issue so the server will have redundant power supplies and hardware RAID
5.  
 
Beyond that,  what do you suggest.  Is memory more important than processor
speed?  Is it important to go with a Multi-processor server or will Zope/
Linux take advantage of a multi processor setup?  
 
 
Dream a little server for me :)

You will have to use Apache + mod_perl + mod_rewrite + Zope.
This way, you send the CGI requests to the cgi-bin, and the
rest requests to Zope. The details could be somewhat involved. :(

(see the following quote in
http://www.apache.org/docs/mod/mod_rewrite.html

`` Despite the tons of examples and docs, mod_rewrite is
voodoo. Damned cool voodoo, but still voodoo. ''
-- Brian Moore
bem@news.cmc.net
)

But it is definitely worth it. And I would guess many people
out there actually use this configuration.

I guess it is possible for someone to write some Zope product
for Perl (a la mod_perl), but it would be major engineering to
be fully compatible with Perl. If you don't mind re-launching
the Perl interpreter every single time (I know, it's primitive),
it's easy to execute the perl command from a Zope external method.

For now, the best bet is probably Apache + mod_perl + mod_rewrite +
Zope.

Hung Jung Lu ,
Along these same lines, I have a C++ CGI App that I would like to call from
zope.  It requires a couple of parameters.  The app can either return HTML
or I can have it save the output to a text file.  Ultimately, the text will
need to be displayed to the user from Zope.
Q1.  How does one call a C++ CGI program from Zope?
Q2.  How do you supply the C++ CGI program with "command line" parameters
from Zope when making the call?

Thanks,

Eric.

The intent of ZOPE is to replace writing CGI scripts. Zope itself often
runs as a large persistent CGI script. It has several advantages over
traditional CGI scripts detail on zope.org.

The general answer is that you'll need to put the CGI scripts in a
non-ZOPE location to use them.

I suggest deprecating your CGI scripts in favor of ZOPE classes.

Oh boy... 10 Grand?

IBM Netfinity 5500 M20

- Dual 700 MHz
- 5 x 9.1 GB RAID 5
- 2 GB RAM
- Dual NIC Cards
- RH 6.1 

Should be about 10 Grand. That thing is ROCK SOLID. It could eat 100
Concurrent users without a napkin. Can handle up to 4 GB RAM, 120+ GB of
Drive and 4 Processors. Almost everything is hot swappable (power, fan, PCI)
only time you would have to bring it down would be to so you could take it
home.

The other way to go would be to get 2 x Netfinity 5000 (Dual 700 MHz, 1 GB
RAM, 3 x 9.1 GB RAID 5). Load balance them and you are golden.

Enjoy...

Subject: [Zope] Zope hosting
Message-ID: <20000322010840.A1674@rosa.sferacarta.com>

Hallo! I'm thinking about using zope to develop some sites.

May you please advise me about a Zope hoster?
I've looked at those listed on zope.org, but some of them offer
just 20MB or have most of the site written in german.
One of them I can't even reach, others don't mention zope on
their pages, or are a bit on the pricey side.

I need a flexible, expandable solution. I may need 40MB and two
domains for a start, and more in the future. I have to install
my products and use pgsql or mysql.

Shell access is welcome, too..

Do you have some suggestion?
Which ISPs do you think are best?

 - OR -

Do you think I'd better install zope as a normal user, on one of
those cheap ISPs that give me 500MB ?


Thank you very very much.

Message-ID: <38D80AF9.3FE3909F@netspace.com.mx>

Hello,
I recently started to work with php (+ Apache), and now I found Zope. At
the first sight, Zope seems to be faster than php, but I don't know if
it's my php application that is not so complex than Zopes objects. So I
would like to ask, is there a benchmarks or articles or any sources that
discuss about performance and developing PHP versus Zope? Also, i am
cuirious, was Zope developed to replace PHP in the future? And what if
PHP comes up with an interface like Zope, so what would be better? Many
questions, isn't it ....

Any comments are welcome.

Thanks.
Nikolai

Field indexes can index any kind of picklable object value, including
DateTime objects.  This is how searching by date is done on the Zope
site.

Use Apache.

Keep the cgi scripts in Apache, migrate to Zope at your leisure.

Zope, more correctly Python will not take advantage
of a dual processor. 
I probably seriously consider buying a ZEO solution
from DC. 
I don't know, but a ZEO solution might solve the 
problem with 100 continuous concurrent users
writing to the ZODB?

Subject: [Zope] Alternating Cols or Colors
Message-ID: <38D813D2.BAB5E068@messagemedia.com>

Does anyone know an elegant way (or a way at all) to alternate what
color rows in a table are or to alternate which column a cell is on?

A less-than-elegant solution would be to somehow assign a variable 1,
check and see if it's on 1, show one color, set it to 2, show the second
color, etc... But I'm not sure what I'm doing wrong with dtml-let to do
that:

<dtml-let c="1"></dtml-let>
  ..

?

Yes it will, it just won't scale exactly two fold.  In almost all Python
wrapped C calls, the C code releases the interpeter lock as often as
possible, this allways happens, for example, when doing I/O or when
calling  database library routines.  Two processors will give you a
noticable benefit.  Four or more will probably not.

Further, Zope will not be the only process running, so a dual gives you
the usual benefits, like doing a compile on one thing without killing
your website.

ZODB FileStorage was not designed to be write intensive, the goal is to
provide a mid-write high-read solution, this solution satisfies 99.9% of
all web site needs.  You would be surprised how much money you have to
pay to Oracle to get, for example, their high write-write distributed
database solutions (its in the six figures).

ZEO is a distributed storage, but in the end it depends on a mechanism
that actual writes the data somewhere.  In the stock case, this is a
FileStorage.  If you want high-write intensity, consider a
BerkeleyStorage (which works fine as the backend for ZEO) or offload
alot of your high-write intensive data to a relational database.

The unique id problem come up again and again.

The automatically generated unique id will benefit web author with

sql row id
object id

and may be some others

With a view that zope will be run over the network with distributed storage
across the net, I would like to suggest we implement a unique id server
which can be a zope server serving on another port and serialize all request
and return the globally unique id.

Does this work?

I also suggest zope can be configured to automatically get the object id
from this service and have globally unique object ids.

As far as multiprocessing goes,  if I were to run a MySQL database on the
same server (serving primarily to Zope) then the multiprocessor config would
be a very big performance boost wouldn't it?

What about Memory?   Again with MySQL.  I suppose I should have mentioned it
right of.  Our main goal is to serve up pages from a database that will be
about 500MB-1GB in size.  There will be very little information which will
be cachable,  almost all of the queries are unique.

Does there have to be any meaning to the keys?

IOW, would a random, unique id work for you?

If so, you can take a look at:

http://www.zope.org/Members/Bill/Documentation/AutoGenID

For ways of doing it. You would insert the generated id into the SQL
table instead of the id field of a zope object.

If you are doing this inside a <dtml-in> tag, you can use the sequence-id-odd
and sequence-id-even vars, thus:

<dtml-in someSequence>
  <dtml-if sequence-id-odd>
    <tr bgcolor="blue">
  <dtml-else>
    <tr bgcolor="red">
  </dtml-if>
  <td> some stuff here</td>
  </tr>

Legacy.  python expressions were added after sequence-item.

Use the namespace object as a mapping:

<dtml-call "foo(var=_['sequence-item'])">

I asked much the same question whilst replying to a very similar question
recently.  the -'s in the names is from times predating Python expressions
(afaik).

to access that var, use the _ namespace:

<dtml-call "foo(var=_['sequence-item'])">

Sure, I do it all the time. The following way is the fastest I came up with:

- Create a style sheet that looks like that:

// even rows
td.listrow1 {
       color:        blue;
}

// odd rows
td.listrow0 {
       color:        white;
}

Then write a DTML method/document (for example displaying objects in a folder):

<table>

<dtml-in "objectValues()">
   <tr>
       <td class="listrow&dtml-sequence-even;">
           <dtml-var title_or_id>
       </td>
    </tr>
</dtml-in>

</table>

sequence-even returns a boolean  set true (1) when we have an even row.

This is untested code, but should work.

Stephan

First, you didn't provide a traceback.  Please allways send a traceback
with an error report otherwise we can't really help you.

Second, I can't reproduce the problem you describe.  I uploaded a file
into Zope, and randomly click a dozen or so checkboxes a dozen times,
and no error ever occur when I click 'Change'.

How, _exactly_ do you get this to happen?

 Our project has a requirement to have all artifacts under source
 control (in this case ClearCase). What is more, our defect
 tracking system is intergrated into our source control system
 such that work done on defects can be traced to versions in the
 source control system. The key requirment is tracability.  Any
 work done can be traced back to when, where, how and why and
 vice versa.

 The problem is Zope. To have meaningful tracability in zope
 means have some system whereby a representation of the zodb
 exists in source control and any changes by users are
 automatically reflected in the source control. The ability for
 the source control versions to be imported back into Zope would
 be a plus.

 Any ideas?

 When building a Product using ZClasses, I often want to create
 a "root" ZClass, which the manager will create in a normal
 folder, and which will then expose the Product's other ZClasses
 in its Add list.  The DTML methods for the root are thus defined
 within this root ZClass.

 The Product ends up looking like::

   Control Panel
    +- FooProduct
       + FooItem_add_permission
       +-FooRoot
         +- FooItem
         +- FooItem_add

       + FooRoot_add
       + FooRoot_addForm
       + FooRoot_Factory
       + FooRoot_add_permission

  Reviewed by:  Tres Seaver tseaver@palladion.com

 Hmmm, I don't seem to be doing so well on picking topics.  Here
 is what I had in mind:

  * This site is an instance of the 
    "ZGotW product":http://www.zope.org/Members/tseaver/ZGotW,
    which has a "main" factory, ZGotWRoot_factory, in its root
    folder.

  * This factory does *not* create an instance of a "folderish"
    ZClass, but rather, creates a normal Folder and populates
    it from a set of default DTML objects, along with a ZCatalog.

  * Individual issues of ZGotW are created within this folder
    as instances of the ZClass, ZGotWIssue, using the code in
    those "cloned" DTML objects.

 My rationale for adopting this approach, rather than creating
 a "folderish" ZClass, was to allow each instance of the "root"
 to be independently customized;  the "common" behavior of a
 ZGotW site is included in a set of utility methods, which can
 be tweaked to enforce different policies, or change the
 look-and-feel of a particular site.

 The downside to this choice is duplication of code:  should I
 find a bug in the original, default code, I have to then fix it
 in each instance as well as the Product.

 Comments, anyone?

Ethan,

Welcome to WorldPilot! (Note: I am not connected with the developers just a
user.)

In order to see other users names in any of the PIM areas those things must be
shared from the sharing page associated with the content type. In the Notes
section it works as follows and I assume similar for the other sections though
I haven't had time to work it through all the paces. If you have browse access
you can see public postings, if you have read access you can see public and
confidential postings. When in Notes any of the users who have shared
information that you can see will become visible. Example:
Tester1 enters 3 notes: 1 private, 1 public, 1 Confidential.
Tester2 has browseable; read access to Tester1's Notes. 
Tester3 has browseable access to Tester1's Notes. 

Both will see Tester1 as an option in the user selection under notes. Tester2
will see 2 notes and Tester3 only 1.

HTH,
Jack

Here is my take on it:

- Never have something high-volume-write to ZODB.
- Use RDBs and LocalFS or other ports to write to the File System.
- If you really need to large data in Zope format look at plugable brains, 
the idea is great.
- I noticed PCGI and Apache increases your performance, especially when you 
serve up big files.
   Setup: Apache using virtual hosts HTTP & HTTPS running Zope PCGI, for 
Images and for large files.
             My Images are served using port 81 and Documents using port 
82. That worked very well so far. We still have to test it live.
- I have two servers running: One for the DB and one for the rest: Mail, 
HTTP/HTTPS, Zope, SSH ...
- Even though not much is going on, the Web server has a constant use of 
400 MB RAM (so I would suggest 512 MB RAM)
- The DB server should be your real performance working horse. Buy a 
computer that will reflect your DB load...get a lot of memory though (1-2 GB).
- Put in both servers a dedicated NIC only for the DB info transfer.

I think that will  get you going pretty well. For the Web server Processor 
power maybe more important than for the DB server. That completely depends 
on how much you team likes SQL (meaning, how much logic is done using SQL).

Stephan

Subject: [Zope] PHP vs Zope
In-Reply-To: <38D80AF9.3FE3909F@netspace.com.mx>
Message-ID: <l03130300b4fe04b0d651@[206.221.224.184]>

In a technological sense, comparing PHP and Zope is a little bit silly,
since they are so very different.  In a practical sense, comparing them
is extremely reasonable, since there are a wide variety of web development
tasks which can be approached with either PHP or Zope.

Performance comparisons are the toughest.  PHP is no slouch -- it is used
for some very high traffic sites, including freshmeat.net and lots of
others.

Zope, on the other hand, offers some features which will cause it to
outperform stock PHP in many cases.  PHP is a scripting language for
website development.  In contrast, Zope is described as an application
server.  As such, Zope includes features like pooling of database
connections and caching of database query results.  These are not
as easy to do in technologies like PHP, and they can make a huge
difference in the performance of database-driven sites.  We
implemented www.CodeCatalog.com twice -- once in Zope, and once in
PHP.  The Zope version ended up much, much faster.  Your mileage
may vary.

I'm pretty sure it's possible to get good performance from PHP and
Zope, if your situation is appropriate and you're willing to work at
it.

I am equally sure that it's pretty easy to get lousy performance from
either PHP or Zope, if your situation is especially inappropriate, and
you're willing to live entirely off the low hanging fruit.

There are lots of other comparisons which could be made, and have been
made.  These comparisons tend to degenerate into flamewars pretty quickly,
although I see no reason for this to happen.  Objective comparisons
of two technologies like this are useful.  I happen to like both, although
Zope certainly gets an increasing share of my attention.

Zope's three-tiered architecture and web-based authoring tends to make
the tool more approachable by people who may be less technical, and
more annoying to hardcore programmers who find they have a new paradigm
to learn.  The gap between the experiences of these two groups of
people tends to narrow very quickly as people start to grasp the soul
of what Zope is all about.  People who are learning Zope tend to
periodically burst out of their office with a desperate need to
tell someone about the latest core principle of Zope which they finally
came to understand.  The more you have these "light bulb" experiences,
the cooler Zope is.

PHP isn't like that.  It's an excellent tool, but it's really just
a scripting language.  It isn't everything that Zope is, and it
doesn't try to be.

Compare PHP to Python

Compare Zope to Midgard.

BTW, the safest way to do those comparisons is *probably* to do them
somewhere other than on this mailing list.  :-)

Subject: [Zope] Zope : Load_site features request
Message-ID: <000501bf93cd$87f93c20$770da8c0@bbs>

Load_site is a greate product.

I am using it to upload a brunch of files to zope now, I found I have an
idea :

In order to make the uploaded zope more alive, I would like the load_site to
make everyfile in the original archive an folder in zope, with index.html
representing the structure of the original html file. And all the contents
goes to obj1, obj2, .... reside on the same folder. For example,

Index_html :

<dtml-var standard_header>
<body><p><dtml-var object1></p><table><tr><td><dtml-var
object2></tr></td></table>
</body>
<dtml-var standard_footer>

This would make the resulting zope site more close to the zen of Zope.

I am not very good in python but please give me some hints to made this
modification. Will you make the change?

Rgs,

Kent Sin

Message-ID: <38D87A4A.FFBE3FF4@fr.bosch.de>

Hi Zopistas

while trying to make gtk's (very useful) Boring Product (slightly
more) interesting, I came across the following (for me) strange
behaviour.

manage_ methods seem to always have "REQUEST=None" as their last
parameter. If I remove the "=None" from manage_edit then I notice no
difference, so the actual parameter is presumably being passed.
However if remove the complete formal parameter (and the reference to
REQUEST in the body of the method) 

def manage_edit(self, title): 
        """does this really need a doc string?"""
        self.title = title
#	if REQUEST is not None:
#	    return MessageDialog(
#		title = 'Edited',
#		message = "Properties for %s changed." % self.id,
#		action = './manage_main',
#		)


then everything still works ! Why is python not complaining about a
parameter mismatch ?

I promise to publish a Howto on making Boring more Interesting when
this madness is  over.

Thanks in advance

Thanks. That is the current work-around that I am using...
(Key derived from a time-stamp with millisecond precision.)
There is one observation and two problems:

(1) ZopeTime is not as good as the getdate() function
    from Sybase, if you are running multiple Zope
    webservers (for load-balancing.) That is, it's
    better to rely on one unique source of timer.

(2) There is a slight chance of two processes getting
    the same key, if they happen to occur within one
    millisecond of each other. The probability is small,
    but unfortunately I have to address even this minuscule
    probability. :(

(3) If the server's time is re-adjusted for any reason,
    it's possible that some keys are regenerated.

I agree that the millisecond-precision key is really good
for non-critical applications. But because of the nature of
our project, we need to address even the slightest chance
of error. :(

I think I will adapt the Sybase's recommended stored procedure
to Zope, by using DTML and ZSQL methods. It's kind of nasty
for something as simple as a surrogate key generation, but it
seems more secure.

thanks again,

Hung Jung

hmm, i must admit that I still can't get it to work with simple 
numbers. I have a field with the number "20002" but it doesn't matter 
wether i use text or field index it still don't work. Am I forgetting 
something ?? And yes - I reindex the cataloge before searching.


But I will look into the date thing right now!!!

Because Zope passes in those parameters that the method asks for. If you take
away the REQUEST parameter, Zope simply doesn't pass it in.

The manage_ methods use REQUEST=None to make sure you can use the methods in
situations there is no REQUEST to pass in. You can call manage_edit with a new
title, and have it still work, from a DTML Method without having to pass in
the REQUEST object, as you won't need the MessageDialog anyway.

Hi.

I am wondering if I can do a search/replace in the ZODB
for e.g. every DTML Document (just like search, but with a replace-with field)?
Is there anything planned or under development?
This would be rather useful to easily use Acquisition
with content imported from HTML files.
Someone could replace a menubar (which appears in all files the same)
just with the <dtml-var ...> call and create a DTML method
which holds this content.

CYa,

I think this is my point exactly ;-)

It all seems really inconsistent and I was wondering if anyone could say exactly what the 'rules'
were and why?

Interesting topic!

How does Zope compare with Midgard?
Which one is more flexible (that is: which one can be used in a wider set of
cases)?
Which one is easier to learn for the webmaster?
Which one is better fit to develop and maintain a complex web site (let's
say: 10,000 documents and 50,000 pictures, updated weekly)?
Which one is better for web sites that uses database and/or a "fragmented
document" architecure (XML/SGML documents that are disassembled and
re-assembled on demand)?
Which one can better integrate other technologies (web-mail interfaces and
so on)?
Which one is easier to use for a remote customer, enabled to develop and
maintain his pages on the server?
Which one is better for "workgroup" intranet servers?
Which one is safer (more anti-hacker)?
Which features does Zope have that Midgard does not have?

Thanks.

PS What does "Midgard" mean (I'm italian...)?

stephan, 

i agree on apache increasing your performance when serving static
files (for instance images), but wouldn't url rewriting and the proxy
pass module of apache be an even better solution? i just switched from
PCGI to the Rewrite/Proxypass combo because of the additional overhead
of PCGI. 

(see http://www.zope.org/Members/anser/apache_zserver/ for the kind of

Mmmhh, I have to have a look. Okay, I just read the the little tutorial. 
Does it really speed things up?
I guess SSL should not be hard using this solution. I will be thinking

Anyone else?

Subject: [Zope] Upload files in Zope and store elsewhere
Message-ID: <38D8B1FC.CCDA0827@funcom.com>

After some helpful advice, I have been successful in uploading files
(images) to Zope. Now I am trying to stuff the uploaded images in a
MySQL database, but am not able to access the image data.

If I try to stuff the image data "raw" into the database by declaring a
image:string parameter to the ZSQL Method and  <dtml-sqlvar image> in
the ZSQL code I get a string like "<ZPublisher.HTTPRequest.FileUpload
instance at 87956214>".

Another approach I have tried was <dtml-var image fmt=sql-quote>, but
this complains about the image being an instance and not a string.

Another approach has been to access the actual "raw" image data using
image.data in various combinations, but I have not gotten this to work
anywhere (contrary to what it seems other people have managed to do),
see this 

http://www.egroups.com/group/zope/26227.html?

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

I'd also love to be able to store files uploaded through a Zope form into a MySQL database so if
anyone else has done this successfully, particularly for medium size files (5-6 MB) please can you
let the list know!

cheers,

Chris

Hm, I _think_ I recall (but I can't test this right now) that the ZSQL
method will only accept values that are given explicitly in its
arguments and in that case it will also acquire them. That would make
sense from a security point of view.
Or perhaps it was a bit more complicated - I have to investigate this

some testing with apache benchmark:

the setup is an apache 1.3.12 sitting on port 1988.

/tstfolder/bmeth is a very simple dtml method ("i am bmeth in
/tstfolder" <dtml-call "REQUEST.set('testvar', 'hm...')">
&dtml-testvar;). 

i do 1000 requests at 50 concurrent users, keepalive-connection via
apache benchmark:

first the result of doing a proxypass to zserver on port 8080:

   --------------------


conclusion: with proxy pass i get around 30% more requests per second
and around 25% less connection time (and im not able to use keep-alive
as it seems).

please note that this is only a quick check and not scientific in any
way, and naturally the benefits will diminish when more complicated
pages are going to be served.

if there are any other test results please let me know...

Hello Marius,

TI am a Newbie to Zope and this is the first time I post a Answer to the
mailing list. But I had the same problem and I hope I can help you.

After a lot of test I find out the following method to upload images to
MySQL and after that retrieve it in the web pages.

Write the folliwing ZSQL method:

       Arguments: N_
                  Titulo
                  Subtitulo
                  Texto
                  Foto

      insert into Novedad
        (N_, Titulo, Subtitulo, Texto, Foto)
      values (
        <dtml-sqlvar N_ type=string>,
        <dtml-sqlvar Titulo type=string>,
        <dtml-sqlvar Subtitulo type=string>,
        <dtml-sqlvar Texto type=string>,
        <dtml-sqlvar
"_.string.replace(REQUEST['Foto'].read(),'\010','\\010')" type=string>
      )

Note that I replace the octal char 010 by the string "\\010".
If you don´t escaape this char MySQL change it for the char 008. I don't
know why.
To upload the image I have the following DTML Method:

<form action="novedades" method="post" ENCTYPE="multipart/form-data">
  <input type="hidden" name="accion" value="insertar_novedad">
  Nş producto: <select name="N_">
    <dtml-in listar_N__producto>
      <option value="<dtml-var N_>"><dtml-var N_></option>
    </dtml-in>
  </select><p>
  Título: <textarea rows="2" cols="20" name="Titulo"></textarea><p>
  Subtítulo: <textarea rows="2" cols="20" name="Subtitulo"></textarea><p>
  Texto: <textarea rows="8" cols="40" name="Texto"></textarea><p>
  Foto: <input type="file" name="Foto"><p>
  <input type="submit" name="submit">
</form>

Note the the line "Foto: <input type=....".
And to retrieve the image I have this DTML Method:

Method name: image

    <dtml-in obtener_foto>
    <dtml-call "RESPONSE.setHeader('Content-Type', 'image/gif')">
    <dtml-call "RESPONSE.setHeader('Content-Length', _.len(Foto))">
    <dtml-var "_.string.replace(Foto,'\\010','\010')">
    </dtml-in>

Note that you must put the 5 lines in the same line (without newlines).

ZSQL Method name "obtener_foto":

      Arguments: N_

      select Foto
      from Novedad
      where
      <dtml-sqltest N_ type=string>

To insert the image in an dtml method:

<img src="image?N_=AC-M56E">

Hope this can help you.

Excellent, just what I was looking for. 

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

and this to anyone who wants to answer: ;-)

   Anyone know why? This is a little disturbing...

Subject: [Zope] Q: <dtml-in sort=twofields>
Message-ID: <E12XlPG-0002fb-00@home.delysid.org>

Hi.

I am constructing a search interface for a catalog.
The objects I index have three relevant properties:
title (textual title)
id (the id, sortable)
book_title (the name of the book where the chapter is included)

I want to have atabular result like this:

Book 1     Chapter 1.1
           Chapter 2.1
Book 2     Chapter 1.1
           Chapter 4.2


To acomplish this I currently do something like:

<dtml-in Catalog sort=id>
  <tr>
   <td><dtml-if first-book_title><dtml-var book_title></dtml-if></td>
   <td><dtml-var title></td>
  </tr>
</dtml-in>

But, to have the list look nice, I'd need to specify
two fields for sorting, book_title should be the primary
field sorted by, and id should be the field all identical
book_title entries should be sorted on.

Is there a way to do this with dtml-in?

CYa,
    Mario <mlang@delysid.org>

btw. does anybody know of other benchmarking software? (i once tried
to grab httperf but the ftp site holding the source is down...)

So ProxyPass is 20 % faster. Cool. I will try that.

Subject: [Zope] Names containing colons?
Message-ID: <200003221420.IAA08813@beluga.mojam.com>

In my web page input forms I've been using field names like "radius:int" so
Zope will coerce variables to the proper type.  This works fine on the
server.  Unfortunately, if I have a JavaScript function on my web page to do
form input validation, how do I reference that object?  Is there some
alternate naming scheme that will allow Zope to do the type cast and allow
references from JavaScript?  Should I just forego the :int stuff altogether
and do the coercion explicitly?

Thx,

In your JavaScript functions, reference the variable as such:

forms[0].elements["radius:int"]

(Replace the "0" with an actual name if you've named your form . . .)

If a "folderish" ZClass had some way to expose its customizable parts, so
that you could go to an instance and say "instantiate a local copy of method

Excellent, just what I was looking for.

I have a few more questions before I try it out:

1. What is the type of the Foto column in MySQL?
   Is it BLOB, TEXT or something else like VARCHAR BINARY?

It's BLOB

2. What size are the files you are storing?
   Small    (< 1MB)
   Medium   (1-5MB)
   or Large (> 5MB)

< 1MB

and this to anyone who wants to answer: ;-)

   Anyone know why? This is a little disturbing...

From Python (either an ExternalMethod or a product)::

  import sys, os, string

  def ExecCGI( cmdLine ):
      """
      Run an external command and return its standard output as a string.
      """
      f = os.popen( cmdLine ) # note that Win32 has a non-standard popen()
      lines = f.readlines()
      status = f.close()
      if status:
         raise "CGI returned error: %d" % status[1]
      return string.join( lines )

To call it from DTML, passing the current values of 'foo' and 'bar'::

   <dtml-let cmdLine="'/path/to/my/cgi %s %s' % ( foo, bar )">
     <dtml-var "ExecCGI( cmdLine )">

Does this fix the FTP problem for Access Rules as well as Site Roots?

I could only get the patch we tried to solve the FTP problem for Site Roots...

I am happily using CodeIt.  They offer several options above "basic" Zope
hosting:

  * Install your own products (this is their "professional" option).

  * Add disk space cheaply (they quoted me $0.50/month for each added 10 Mb).

  * Add domains, mapping them to separate Zope folders, for $10/mo each.

> Shell access is welcome, too..

They don't offer shell access -- I FTP products, export files, etc., into a
"home directory" with a slightly oddball layout.

Zope wants to be a long-running process, with significant CPU and RAM
requirements;  most ISPs don't appreciate you running such a beast, so ask
first.

Subject: [Zope] Zope Weekly News
Message-ID: <Pine.BSF.4.21.0003221005110.8916-100000@geekbox.metamike.net>

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday before Noon.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * Two new Zope revisions were released this week.  2.1.5 filled in
    security holes which affected sites which allow untrusted users to
    create DTML documents.  Ironically, a bug-fix which was included
    in 2.1.5 broke code which depended on the bug.  This was fixed in
    the second release, 2.1.6.

    http://www.zope.org/Products/Zope/2.1.5/Zope_215_release
    http://www.zope.org/Products/Zope/2.1.6/Zope_216_release

  * Thanks to Eduardo Fernandez Corrales, the Zope Weekly News is now
    available in Spanish!  He is publishing translations at Zope
    Hispano, a portal for Spanish-speaking Zope developers and users.

    http://zope.sistelnet.es

  * Healtheon | WebMD is hiring in Atlanta, GA

    Healtheon | WebMD is looking for Software Engineers with
    experience in Python and/or Zope to work in our Global News Center
    located in Midtown Atlanta, GA. You must be willing to relocate.

    http://www.zope.org/Members/kbirch-webmd/hiring-notice


New Products

  * The Portal Toolkit has been packaged into a snapshot release for
    use by those who do not have access to CVS.  The PTK is targeted
    at community-oriented portals, but is also appropriate for any
    site which wants to give members a personalised view of content.
    The snapshot release is 0.7.1.

    http://www.zope.org/Products/PTK


Updates

  * Software Product: load_site.py with additional features, by Itamar
    Shtull-Trauring

    Itamar has updated his powered-up 'load_site.py' again.  The
    present release is 1.3.1.  This update adds a GUI, built with
    wxPython.  'load_site' is a utility for dumping content from a
    file system into the ZODB.

    http://www.zope.org/Members/itamar/load_site

  * Software Product: ZopeEDIT, by "jimbag"

    The latest release of this product, 0.0.5, adds limited RPC
    support which is used to create and delete folders.  ZopeEDIT is a
    tool which enables any text editor to edit content on a live Zope
    server.  It does not need to run on the same machine as the Zope
    server.

    http://www.zope.org/Members/jimbag/ZopeEDIT/

  * Software Product: LocalFS, by Jonothan Farr

    Version 0.1.6, the Ides of March release, fixes several bugs, is
    more robust about determining file types, and creates XMLDocuments
    and StructuredDocuments automatically, where appropriate.  LocalFS
    is a product which allows Zope to serve files out of a local
    filesystem.

    http://lists.zope.org/pipermail/zope-announce/2000-March/000130.html

  * Software Product: SiteAccess, by Evan Simpson

    Evan has release version 1.0.1 of SiteAccess.  This version fixes
    a bug which interfered with FTP access to Zope.  The SiteAccess
    product allows Zope to serve different content depending on the
    hostname the site was accessed by.

    http://www.zope.org/Members/4am/SiteAccess

Zope.org items

  * How-To: VersionFTPServer, by "htrd"

    This How-To describes modifications to Zope which allow you to
    work within a Version through FTP.  Versions allow you to stage
    changes to a Zope site by effectively forking the database.
    Changes that you make in a Version are not publicly visible until
    you ask them to be.

    http://www.zope.org/Members/htrd/howto/VersionFTPServer

  * How-To: How To: Use GenericUserFolder with an SQL database Version
    1.1, by "hippy"

    This How-To shows how to customise GenericUserFolder(GUF) to use
    an SQL database as its repository for usernames, passwords, roles
    and anything else you want to store about a user.  The update adds
    information from Dennis Baker to help get things going with MySQL.

Midgard is a PHP and MYSQL integration.  Midgard uses MySQL the way Zope
uses ZODB, as well as relying on MySQL for the things that Zope can use
other databases for.  I would assume that Midgard is a logical step for
those coders that are used to making database-driven dynamic web pages
with scripting languages, and is probably intimidating to those that
don't come from that background.

On a brief overview, Midgard seems to want to exert more control over
your approach to content.

[snip questions I can't answer]

> Which features does Zope have that Midgard does not have?

Well... Zope is object oriented, transactional, can interface with a
variety of databases, uses and is written almost entirely in python. 
The web-management seems more robust, but I could be out to lunch.

> PS What does "Midgard" mean (I'm italian...)?

Midgard (should be Midgaard or Midgĺrd) is the Norse word for the
material plane, as opposed to Asgĺrd (the realm of the gods).

but be careful, since this is a security hole.  the executed command line

Hi,

The company I work for is getting into Zope hosting.
We're based in the UK and are pretty open minded since we've started doing a fair bit of work in
Zope ourselves.

If you or anyone else is interested in European Zope Hosting with a flexible, open-minded ISP (of
course, I would say that ;-) then contact 
Simon Coles (simon@nipltd.com) or myself.

Hope this helps,

Chris

I messed around with this a little bit before giving up, though I'd like it to
work....

The problem (as I see it), is that 1) you have to get to the data and 2) you
have to format the data properly so that the database stores it properly.  What
I've gleaned is that the binary data will contain characters that confuse
whatever DA you're using (I use the ODBC adapter).  This means you'll probably
have to replace these 'confusing' characters with their 'safe' counterparts.
For the person who got it to work, it was the 0x08 character.  I believe other
DB's will choke elsewhere.  I never could figure out which characters needed
replacing and with what, so I wrote an external method to save the file and just
wrote the filename/location/upload info into the database.

This wasn't as nice as I wanted (I had security concerns putting anyone's files
on the hard drive), but it will probably work (I get sidetracked once I got the
file saved and haven't finished that project).

Let me know if you get it solved (I'm using ODBC to a cheap acess database).

posting.

Looking through Image.py I see quote a few methods for accessing the
image as a "web" object through the use of URL. Internally, Image.py
uses the data attribute extensively, but I have not been able to access
this from within DTML (and I guess this has to do with data not being
listed in either the properties or permission sections of Image.py).

My final try will probably be to resort to using an External method to
get access to the "full" Image.py object (including data), but I was
hoping to avoid this.

Has anybody done this (uploading in Zope and storing the data outside of
Zope) successfully? If so, please give me a hint..

Thanks,

Marius Kjeldahl

I use Rackspace.com which is certainly not as cheap as other hosting
providers but for under $200 you can get a fully dedicated 350 MHz, 64MB
RAM, 8 GB HD and RH 6.1. So, in the end you pay about 2 to 3 times what
another hosting provider has but it is your machine. You can install
whatever you please, configure it to your hearts content and never have to
worry about what someone else will say. Zope loves its own machine.

I have found their support to be great and they do a 24 hr turn around for
new accounts.

Worth every penny (twice the penny if it is for your company).

I think the best analogy is to think of ZSQLMethods, ExternalMethods, and
PythonMethods like "normal" functions in C:  they receive information via
arguments, and acquisition is always done via one of the explicitly-passed
arguments.  DTMLMethods/Documents are in some ways more like C macros:  they
grab information from the surrounding DTML context, without having to be told
what they can "see".

The analogy breaks down at the "call site":  Zope looks at the explicit
parameter lists and tries hard to match arguments to any parameters which are
not explicitly passed by the caller:  normally, it does this by looking them up
in the REQUEST object, *not* in the current DTML namespace.  Therefore, whenever
calling a non-DTML method (External/Python/ZSQL/...):

  * poke all interesting values into the REQUEST object before calling::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-call "REQUEST.update( { 'bar' : 42, 'baz' : 3.1415926 } )">
     <dtml-var foo>

    This version has the advantage of avoiding the "expression" syntax
    of DTML, but does require polluting the REQUEST namespace (may be
    an actual advantage if multiple methods use the same values).

  * pass the values explicitly, using positional arguments::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( 42, 3.1415926 )">

    This version looks most "natural" to a programmer, but is fragile WRT
    changes in the parameter list (changing the order of parameters on the
    method silently breaks this call).

  * pass the values explicitly, using keyword arguments for clarity::

     <dtml-comment> calling 'foo( bar, baz )' </dtml-comment>
     <dtml-var "foo( bar=42, baz=3.1415926 )">

    This version, which I prefer for any method taking more than one argument,
    says explicitly what it is doing, and therefore eases maintenance.

Message-ID: <6D8A17398E28D3119F860090274DD7DB4985FA@pces.cadlab.it>

Python is quite slanted toward this kind of applications:
1) very clear sintax (many webmasters are not particularly fond of C and
Perl, like me...)
2) strong support for string management and a very good regular expressions
module
3) wide choice of modules for interfacing with web servers, mail servers,
database, etc...
4) ready-to-use modules for HMTL, Mail messages and XML manipulation
5) tons of good documentation, examples and a very active community
6) hard-rock core system and reliable modules
7) indipendence from the platform (Python runs almost everywhere. I'm
re-compiling it for my Z80-based microwave oven...;-)

Despite this, I think that the real reason why they decided to use python
was the terror to commit a mortal sin (like touching a Perl interpreter) and
the desire to live immersed in the light of the true Faith. 

I would have done the same...

This is great, some light at the end of a very dark tunnel.  One
question here:

How where you able to get strace to work?  I've been trying and it
either would lock Zope up or just return instantly.

Yes, we noticed that to.

Is this only when accessing via FastCGI or does happen when using
ZServer as well?

Thanks for the info.  If we find anything out I'll let you know.

My advice here is not based on work with Zope, but on years of painful RDBMS
experience:  I do *not* recommend storing large BLOBs in any existing RDBMS --
they aren't built for them, and generally make your life miserable when you
try.  Most of the reasons you would choose to use an RDBMS (performance,
replication, stability, searchability, etc.) don't apply when it comes to large
BLOBs;  you are still much better off storing the "BLOB" in a filesystem
somewhere, and then storing a path/URL to it in the RDBMS.

With Zope, BLOBs present another issue:  because they aren't standardized, each
RDBMS has a proprietary API for BLOBS;  the Zope database adapter therefore has
to have custom code for each RDBMS, making the BLOB code one of the likeliest
sources of weird, hard-to-reproduce bugs I can think of.

In short, *don't go there*.  Really, I'm serious.

Tres.

P.S.  If you *have* to go there, use the Python base64 module to encode
      binary data.

No such decision was ever made. When Paul Everitt and Rob Page founded Digital
Creations (a history I know only from Paul's and Rob's telling me, I could
well be out for lunch on this), Paul was getting quite heavily into Python
already. He convinced Rob that it might be a good language to base their
development on.

They then hired Jim Fulton, then already a very active Python contributor (he
hosted, if IIRC, the 3rd and/or 4th python conference or something). Under his
technical guidance software was developed that only in November/December 1998
came together to form Zope.

Many parts of what is now Zope, like Bobo (predecessor of the ZODB), DTML
Templates, Extension Classes and Acquisition where already Open Source, and
heavily used by the python community. When Zope came to be, all those parts
were mixed with things like Acquaduct (now database adapters and ZSQL
Methods), and Principia (now the web management interface and many of the
stock Zope objects like File and Folder), that were commercially sold by
Digital Creations.

So, python made Zope and its power possible. If you now decide that you want
to go and build Zope in a different language, you will first have to try and
build all those parts from which Zope came to be. And this will be pretty
hard, if not impossible. Pythons clarity, OO orientation, extensibility and
last but not least Jim's technical excellence with python will be greatly
missing.

I think it had to more with Jim Fulton's "zealos object-orientedness" than
that -  Zope is a system for publishing python objects on the Web.

I suggest that you negotiate with service provided over the terms of the
service agreements. You might find that they are more flexible than their
web pages indicate. Or you may influence them to change the standard service
agreements. I use CodeIt Computing and am happy with their service.

The implementation I sketched out a version of the Prototype pattern, I think. 
Exposing the customizable bits is more like a TemplateMethod:  this would play
nicely with Acquisition, perhaps::

  <!-- Inside the index_html method of a "folderish" ZClass -->
  <dtml-if custom_foo>
    <dtml-var custom_foo>
  <dtml-else>
    <dtml-var default_foo>
  </dtml-if>

The trick then becomes giving the manager enough information to know how to
implement 'custom_foo'.  My current hack solves this by cloning the default bit
as a starting point -- perhaps the factory could clone 'default_foo' as
'sample_custom_foo', or something?

Based on previous e-mails here, I have read that Zope does not support
server-side includes.  Is there a way to get around this in reference to
an img src, as in the following:

<img src="myprogram?-action=gif&amp;yadda yadda yadda>


Basically what I have here is a page that includes other documents (maps,
graphs, etc.) via server-side-includes.  If there isn't any way around
this, then I may have to forgo Zope for now...too much of my system
depends on this sort of thing.

The example for finding items to catalog doesn't work for me.  When I enter
getNodeName()=='entry' in the 'expr' field I get the following error:
 Error Type: NameError

Message-ID: <B059671903C6D211A0D500C0F0301C792B2714@kubrick.mop.no>

Adding a SiteRoot object to some folder upward from a ZDConfera topic
("Confera Topic" object) will break the topic.

It seems that when adding a message, instead of inserting a valid
message object, ZDConfera ends up adding a corrupt object. At one point
ZDConfera, when I tried adding a follow-up, duplicated the parent
message instead of adding the reply, resulting in a circular reference
that only a database restore would fix.

This is Zope 2.1.4, SiteAccess 1.0.1, ZDiscussions 0.2.0, on Slackware
Linux 2.2.

Here's the traceback.

I would like to know why the following happens, and what I can do to fix
it:

I have a ZCatalog instance in my root folder called Catalog. I have some
CatalogAware ZClasses that get added to it automatically.

The problem is, when I query Catalog for results, it only shows the
elements that were present the last time I clicked the "Update" button in
ZCatalog. The new elements are present in the catalog, but they don't show
up in the query until I manually update the catalog.

Here's the query code:


<dtml-in "Catalog(meta_type='Track', track_hasfile='on',
track_active='')">
  <li>
  <a href="<dtml-var "Catalog.getpath(data_record_id_)">/approve">
  <dtml-var "Catalog.getpath(data_record_id_)"></a>
</dtml-in>

Any help appreciated. Please CC me if you answer.

Here's the scenario that I'm dealing with (all of this works w/o Zope,
i.e. static content):

  - user starts at www.mydomain.edu (http)
  - user goes to www.mydomain.edu/internal which is secure (https) and
    requires a password for entry
  - all pages under www.mydomain.edu/internal are secure (https)

I'm having trouble getting this to work with out Zope-ified site, however.
What I would like is to have Apache handle all password authentication, and
I would like it to happen over ssl.  Is this possible at all?

Any help would be appreciated.

Thanks in advance,

Just a few thoughts.

Simple workaround: make the id field unique. it would seem to me that
you could then use a try/except clause that tried to insert the data
into sybase, and redreate an id if it failed due to the id already
existing.

Additional options:
 o add a randomly selected letter (or two) to the numerical id. Now the
odds that any two servers, or a change in time, will obtain the same key
are extremely slim.
 o Randomize the order of numbers in the 'timestamp'

Combine these with the unique restriction above, and you should have a
_very_ scaleable, an relatively easy to implement, solution.

Subject: [Zope] Casting to a list
Message-ID: <38D91168.F163496@messagemedia.com>

Another question (soon I'll start answering more on this list :) - I
have a set of checkboxes with the same name that I iterate through
using dtml-in. However, when only one checkbox is checked, dtml-in
complains that a string cannot be used as input, it expects a
sequence. My initial thought was to do this:

<dtml-if "type(var) == type('')">
  ... (do not iterate)
<dtml-else>
  <dtml-in var>
    ...
  </dtml-in>
</dtml-if>

How can I either cast a string to a list w/o messing up an existing
list, or gain access to Python functions such as type() from a
dtml-if statement?

Zope in a sense replaces server-side includes with <dtml-var>.

What you need to do is upload the images to Zope in whatever folder
is appropriate. To do this, select "Image" from the create item menu
found at the bottom of your Zope "Contents" screen. Select the images
you would like to upload, and submit.

The images will then be in your object hierarchy.

You can reference them using either
  (1) Manual <img src="...">
  (2) Using dtml-var (the Zope way of doing things)

Say, for example, you uploaded an image called foo_jpg (Zope does not
allow dots in object names). You could reference it from any object in
the same folder as the image or nested folders using dtml-var

	<dtml-var foo_jpg>

Zope will automatically insert the height and width attributes and so
forth. To remove the border, you would use...

	<dtml-var "foo.jpg.tags(border=0)">

(I think)...

There are some interesting HOWTO's on this topic at zope.org.

I quess Zope is more "object-oriented" as it is based on an OO language.

OTOH, said OO language itself has been implemented in OO and non-OO 
languages (java and C) ;)

Probably the less flexible one ;) I don't know which.

There is currently a 2 Gig native (Zope internal) database size limit. 
This won't apply when you use external database or sore files in file system.

Bot are wll supported on Zope. Dunno about Midgard.

Zope has integrated a lot, so does PHP - you probably find most popular 
"other technologies" supported/supportable on both.

Probably Zope (this is a Zope list)

The one you know better :-p

I guess they are about the same. The one that will be used more will 
eventually be safer due to more eyballing.

Both can be configured to be insecure ;)

Howdy everybody.  Last night at the Bay Area Linux Users Group meeting I
announced that we are going to make ZEO Open Source and thus a
first-class feature of the Zope platform.  For more information:

  http://www.zope.org/Products/ZEO/

Some quick notes:

  o A first release for a very small, qualified group of testers will
happen mid-April

  o General release some weeks after that

ZEO (Zope Enterprise Option) turns Zope into a *distributed*
transactional object system, allowing people to add processors,
machines, and networks to scale their web applications.

Ok,  I've butchered the original message because it was too long to read.
It looks like Proxy Pass is the best way to go.  Can you use Proxy Pass with
SSL?  ZServer alone is not a choice because SSL is a requirement.

You know after reading this thread I was pretty surprised that we didn't
have simply execcgi ability in Zope, considering how trivial it is.

I'll look into something like this possibly being a feature.

It sounds like this is probably coming from an SQL database? If it is
modify the query you're using to sort on the DBML-side. If your
query looked like:

	select * from books

You would modify it. Having mutliple levels of order by varies from
DBMS to DBMS, but it'll look something like this:

	select * from books order by book_name, id

Or something to that effect.

Sorting using the DBMS is more desirable as well because the DBMS
is likely to sort it more quickly, with all its indicies and so
forth.

If you tell me which DBMS you're using, I probably know exactly
what you should do to your query.

Ihis didn't work, then?  Looks better than what I came up with, which, for the
list vs. string situation goes like:

<dtml-try>
  <dtml-in string_or_list_var>
   list stuff...
  </dtml-in>
<dtml-except>
  non-list stuff...
</dtml-try>

If you have a string with multiple values to split, use the _.string.split()
function, as...

<dtml-in "_.string.split(str [,separator])">

This will probably choke on lists, though.  Combine the two for a wholesome,
good-start-to-your day breakfast code. :-)

This is less of a Zope issue and more of a DBMS issue (which is why I
can answer it)...

There are two ways to get global unique ID's:
  - Have a unique ID server
  - Find a way two servers can come up with ID's unique to each other
    without talking to each other. This is a lot of fun, and is done
    by using the network card's ID number, which is statistically
    unique. Basically, if you use the computer's network card ID, you
    can generate statistically unique ID's (this, incidentally, is the
    MS SQL Server way[*])

[*] I in now way indorse MS SQL Server. Please do not flame me for
mentioning it; I know it's a peice of crap. :)

The former is more elegant, but the latter is sometimes more practical
for distributed systems. At any rate, there is no simple solution to
this problem (many companies have had major research into this area
with little results). Your best bet is to keep this out of Zope and
just set up a unique ID server.

Have your databases (Sybase?) establish foreign links to the unique ID
server. Then, write triggers that grab ID's when rows are insert. Say
you had two tables, on two servers, that need to have unique ID's.
You would omit their ID fields upon doing an insertion, making them
NULL. You would write a trigger on insertion for these tables that
would detect the NULL id field, grab the unique ID from the unique ID
server, and insert the row with the unique ID.

In very large environments with lots of data importing, this can be
a large strain on the network and the unique ID server. If this is
the case, be sure to have good bandwidth between the servers. And
as always, bigger servers means more performance. :)

The simple answer is: you don't need to cast. :)

Zope provides a solution: your specify in your multiple-select
a name like varname:list, and Zope will automatically cast it
into a list. That is, append the ':list' to your variable names.

Thank you for your input..I think I need to explain myself a little
better, however.  I have no trouble with a static image...the trouble I am
having is with images created on the fly.


For example, I have a cgi program (which I would like to continue residing
in my linux structure.....static pages I would like to be in
my Zope structure).  This program will generate a graph based
on the time units, and whatever particular data sets I pass as parameters
to the program.  So, the image can't be stored on  Zope, since the image
may be different each time it is brought up...for example, I have the
ability to pass the word "today" as a parameter...this means that
everyday, the graph generated will be different.  Is there a way for
Zope to respond to a cgi program that's being called as "img src" value?


Thanks,
Jessica

My understanding from a recent discussion was that it happens on all platforms 
with 32-bit ints regardless of weather they support large files or not.

does ZDB use longs internally and just some small part strangles it to 32-bit,
or is it something more widespread ?

Message-ID: <B059671903C6D211A0D500C0F0301C792B271A@kubrick.mop.no>

I use identity columns with Sybase -- the only problem I've experienced
is a tendency to occasionally "burn" ID values, resulting in gaps.

If you're not worried about non-sequentiality, identity columns are
generally not a problem. Do you anticipate crashes? I have run Sybase
for about a year, and never experienced a single crash -- meanwhile,
Zope has crashed and/or been restarted many, many times.

Aside for identity columns, here's an alternative scheme I used some
time ago with an  Access database (where, aside from DAO/ADO, you simply
cannot obtain the previously inserted "autoincrement" value, causing
problems for web-based forms): Create a table such as this

	create table Ids
	(
	  Id int
	    not null
	    primary key nonclustered
	)

Then create either a stored procedure (don't like 'em) or a Zope DTML
Method that will (a) get the lowest available ID, and (b) if the table
is getting empty (count < delta), then replenish the table with new,
unique values, starting at the ID you just obtained. (If the table is
empty when you start out, assume this is the first time the method is
run, and simply start with a seed of, say, 1.)

Because of transaction logic, IDs will never be "burned", and the only
gaps you will experience will come from IDs that disappear when their
parent records are deleted.

Hope this helps.

Hi there,

I'm trying to connect to an Oracle 7.3 database through Zope using a 'Z
ODBC Database Connection'.
It's giving me an error saying:
'Invalid connection string: gsmInfo'

I set up a DSN throught the Control Panel as follows:

Data Source Name: gsmInfo
SQL* Net Connect String: 2:
UserId: testowner

This is using the 'Oracle73 Ver 2.5' Driver.

I also used the '32-bit ODBC TEST' that comes with Oracle and this
connected to the database no problem after entering in a password.

Has anyone got any clues or suggestions to the problem.

Thanks in advance,

Michael Gannon.

Subject: [Zope] img src (newbie)
References: <Pine.OSF.4.02.10003221254190.24303-100000@batman.tamucc.edu>
Message-ID: <38D929CF.42FD9EBB@messagemedia.com>

So, you have a CGI script that dynamically creates an image as its
output. You'll either need to re-implement this using Python and make
a ZOPE product, wrap it using a Zope product (which seems the least
elegant), or just keep it out of Zope (probably the desirable). I
assume you're running apache and using Zope.cgi, so your Zope path
is

	http://yourhostname/Zope

Now, your CGI scripts are under:

	http://yourhostname/cgi-bin

You'll just want to reference the images just like you would in
normal HTML. Zope will not mess with an img tag, so if it points
to a working CGI script, you're ok.

Does that answer your question?

Subject: [Zope] Role weirdness
Message-ID: <m3em92zrw9.fsf@wacko.pdx.net>

I have a site containing some content users need to register to see.
The way I set this up was:

/premium/acl_users[GUF]
Using GUF to authenticate and assign users a role of
contentSubscriber.

At one point in time, I created a user defined role at the root level
of my Zope called contentSubscriber.

I then changed the security on /premium to require contentSubscriber
role to view or access content information.

Now, I can't seem to find any mention of a contentSubscriber role
anywhere in my Zope management screens OTHER than by looking at a user
through /premium/acl_users/userList.

None of the Find/Advanced... screens mention my contentSubscriber role
either.

The odd thing is that my access control scheme appears to work.  Other
than my random hourly crashes.

That doesn't look like a valid connection string. Usually, the connect
string is something like:

        user/password@sid

At least using the normal Oracle interface. SID, which I assume would
map to ODBC would be the datasource name defined in your tnsnames.ora
file.

You might try testowner/password@gsmInfo

Or consult your ODBC docs on proper connect strings.

Sure.  I'm using mod_ssl and apache 1.3.12:
My conf is like this:

<VirtualHost 216.17.170.666:80>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
</VirtualHost>
<VirtualHost 216.17.170.666:443>
   ProxyPass / http://imeme.net:6666/
   ProxyPassReverse / http://imeme.net:6666/
   ServerName imeme.net
   ServerAdmin mindlace@imeme.net
   ErrorLog /path/to/apache/logs/error_log
   TransferLog /path/to/apache/logs/access_log
   SSLEngine on
   SSLCertificateFile /path/to/apache/conf/ssl.crt/server.crt
   SSLCertificateKeyFile /path/to/apache/conf/ssl.key/server.key
</VirtualHost>

I have zope actually running standalone on port 6666.  Then I use
SiteAccess.
The access rule should look like this for you:

look for internal, then munge the result to be 0 if not found:
<dtml-if "1+(_.string.find(PATH_INFO, 'internal'))">
  <dtml-call "REQUEST.set('SiteRootBASE','https://www.mydomain.edu')">
<dtml-else>
  <dtml-call "REQUEST.set('SiteRootBASE','http://www.mydomain.edu')">
</dtml-if>

then you want to put a SiteRoot object in your root folder, leaving
everything as per default.

As long as your first links to /internal are written as https:// the
austhentification should be over ssl. The access rule makes sure any
dynamically generated URLs under /internal are written as https://

Subject: [Zope] Roles, Local Roles, and so on
Message-ID: <20000322213020.A16021@owl.rhein-zeitung.de>

Hi,

I have a question concerning the Role and Local Role system. Well, am I right
with the observation, that Local Roles are only locally assigned global roles?
For example I have an user "oandrich" which is globally just a member of Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to get
really local roles?

Bye, Oliver

emphatically yes- see my message to Erick Mechler re: httpd.conf help.
There are some complications with virtualhosting, because zope only sees
whatever it's listening to, so you have to have a different
<virtualhost> directive for every virtual host as opposed to just
letting zope handle virtualhosting.

phew.

I use a wrapper sql method called UserSettings.

Any calls to data are wrapped in a call to UserSettings eg.

<dtml-in UserSettings>
...
</dtml-in>

UserSettings SQL is : "select * from online where username=<dtml-sqlvar "_.str(AUTHENTICATED_USER)" type=string>"

The online table has columns for data (user name , etc) as text and memos  and permissions (is_super, edit_media...) as logicals
(True/False)

I use the returned information to decide whether an item is displayed or how it is displayed.

No, its a dtml-in for a ZCatalog.
Can I pre-sort the catalog for one MetaData field, and sort the dtml-in
for the other one?

Or are their any easy ways to modify the dtml-in tag to handle multiple sort fields?

Note that the version I posted has several rough edges:

 * It doesn't propagate the CGI environment to the child process.  We
   could fix this on Unixen by doing a fork() and some execve() magic,
   but then we lose the convenience of popen();  CreateProces() on Win32
   requires special handling, too.

 * It doesn't propagate the input stream some CGI's may expect to find.
   "Temp files and fork() and dup(), oh my!"

 * Win32 versions to use the win32.popen(), instead of os.popen().

 * The error handling is ugly.

 * It double-buffers results (which could get ugly if the CGI does
   weird stuff, or returns a really huge result).

In short, its a pretty ugly bandaid, recommended only for easing the CGI
withdrawal jitters. :)  Doing the Right Thing (TM) involves reimplementing a big
chunk of a web server, which is probably why Zope Didn't Go There already. 
mod_rewrite looks pretty sane by comparison.

Message-ID: <1BCCE632C91CD211982D0001FA7EAE6C02E6A09A@express.sematech.org>

I have a dtml-method page that displays a table of values and allows the viewer
to delete on of them (using an sql method on the next page).  All works as
expected, but I noticed an odd thing:  when I used the back button on the
browser the table of values was not updated, but showed the old values.  This is
bad, because people will think their delete did not work.

How do I force a page update?  I checked the IE5 options to make sure it was
checking the date stamp on every visit, so I don't think it's a cache issue,
though I don't know enough about browsing to say it isn't.  Shouldn't forms be
re-submitted on the back button?

I'm sort of confused how this is all handled....

Environemt propagation after a fork wouldn't be too hard, and I was
kindof assuming punting on Win32.

There wouldn't need to be much, just catching errors from the Zope side
code, anything the CGI raises is it's own problem.

I strongly suspect that this is a symptom of a known (to me) incompatibility
between SiteAccess and ZCatalog.  If ZDConfera uses a ZCatalog to track
topics, it will not be able to retrieve them correctly.  I have a patch to
ZCatalog to fix this, but it hasn't been tested by anyone but me.  It just
replaces the resolve_url method of ZCatalog with one that doesn't reenter
ZPublisher.  If you're willing to test it, I'd be happy to send it.

Subject: [Zope] How do I get the owner of a document?
Message-ID: <20000322224211.A16366@owl.rhein-zeitung.de>

Hi,

may be I am just to dumb or something like that, but Zope has to now who is
the owner of a certain document. This is for sure, but how can I get the owner
of a document from DTML or an external method? I read through the sources and
maybe I am just to dumb or so to find it, but I can't find any manage_* call,
that tells me how to do this?

I have to write a small DTML method, that finds all documents, that are
located in a givben hierachie which are owned by a certain user.

Bye and many thanks,

    OLiver

P.S.: Don't frustrated that I ask these things again and again, but now I have
to deal with things in Zope, that I haven't dealt with before. ;-))))

Please send me the patch. The problem does not seem to have anything to
do with URLs, but rather the objects indexed by the topic -- but I could
be wrong here.

Is there a way to modify ZDConfera/ZDiscussions to fix the problem,
without patching ZPublisher? I wouldn't want to break something else in
the process.

I think maybe the issue got clouded by the phrase, "server-side includes".
What you are asking for is not a server-side include:  you want to generate a
tag in Zope, something like:

  <img src="build_graph?units=hours&series_a=hit_count&series_b=load_factor">

This isn't SSI because the browser makes a separate request for the image,
after/while loading the page containing the tag;  SSI is massaged by the server
before the browser ever sees the text.

That said, it *is* feasible to build a parameterized image link, using exactly
this kind of syntax.  There are a couple of contributed products which do
on-the-fly image generation:

  * "gdchart":http://www.zope.org/Members/teyc/ZGDChart 
 
      "draws charts using data from your ZSQLMethod"

  * "TTImage":http://www.zope.org/Members/RainDog/TTImage

      Converts text strings into a GIF/PNG/JPEG images using
      TrueType fonts.

I may have even missed one -- check out the "Zope
Products":http://www.zope.org/Products page.

Without patching ZCatalog, you mean? Hmm.  Possibly.  If ZD* were patched to
use a subclass of ZCatalog which overrode resolve_url, that would work.
Here's the replacement resolve_url for ZCatalog:

    def resolve_url(self, path, REQUEST):
        """
        Attempt to resolve a url into an object in the Zope
        namespace. The url may be absolute (site-relative) or a catalog path
        style url. If no object is found, None is returned.
        No exceptions are raised.
        """
        pparts = filter(None, string.split(path, '/'))
        try:
            obj = getattr(self.aq_parent, pparts.pop(0))
            while pparts:
                obj = obj[pparts.pop(0)]
            return obj
        except:
            return

Yes, most browsers do this.  It's simply a result of their caching.

The only way i know of involves catching hits to the back button involving
JavaScript.  Not pretty, IMHO, nor terribly portable.

Message-ID: <B059671903C6D211A0D500C0F0301C792B2722@kubrick.mop.no>

If the object inherits from CatalogAware, you get a bonus method called
owner(), which you can call like so:

	<p>The owner of this document is <dtml-var owner>.</p>

If not, you can use the get_local_roles() method. You need to iterate it
-- best with an External Method. Like so:

	def GetOwner(self):
	  for Role in self.get_local_roles():
	    if 'Owner' in Role[1]:
	      return Role[0]
	  return 'Zope'

Add this External Method at top-level. Then, thanks to Acquisiton, you
can access the value in any document thus:

	<p>The owner of this document is <dtml-var GetOwner>.</p>

Hope this helps.

Yikes, just noticed this one sat in my outbox unqueued :

Going back a month, just have to say thank you Chris.

It does work - I was getting the earlier error messages due
to being a bit ambitious and trying to display all of the 
images.

Just for the record, to get it to work :

1. Create a ZSQL method <ZSQL_SelectPicture> to extract the binary data 
   field ('picture') of one (1) image. That's the important part - one 
   single image.  Don't try to select several records for further logic
   processing.

2. Create a DTML method that returns nothing more than the 
   BLOB data from the ZSQL method, with the correct content type.
   Eg. 
  <dtml-call "RESPONSE.setHeader('content-type', 'image/jpeg')"><dtml-in
ZSQL_SelectPicture><dtml-var picture></dtml-in>

Accessing the DTML method directly will return the image.

This is stunning news.

Still absorbing this, but I think this will have ...interesting... ramifications for Zope in the marketplace.

From the Fact Sheet
"In summary, the ZEO architecture provides the power, flexibility and intelligence needed for the most demanding web applications."

and to think I wasn't going to check my email tonight.

thanks Paul!

Subject: [Zope] Use of Zope for data entry intensive app re-write
References: <38D950FC.F6B7CE47@voyager.net>
Message-ID: <38D96220.DCCD37EE@digicool.com>

I would imagine so... DC has written apps that handle intensive data
entry.. Zope gives you stuff like a security framework, a relational
database interface, a built-in object database, a document templating
language, undo, remote procedure calls from other machines, more.   

But the number of "screens" your application owns isn't really enough
information on which to provide a meaningful judgment.  Does your
application require delegation of authority?  Multiple security levels? 
A management interface?  Personalization?    Would it benefit you to be
able to run the app on multiple platforms without source code change? 
Does XML-RPC buy you anything?  Does FTP access to the ZODB buy you
anything?

Additionally, in the end a decision should generally take in to account
to how comfortable and familiar you are with a product.  If you're new
to Zope, Python, and OO, and you're under the gun to get this project
done and meanwhile you have 7 years of Perl experience, you may want to
seriously consider using Perl.  On the other hand, if you're curious
about Zope, Python, and OO, and you want to get some experience and
you're not tied to anything else in particular, Zope starts to look
really attractive.

Arghh... I should have been more clear, hopefully
someone else already has told you in the meantime,
but if not, the colons should be in the HTML FORM
fields, not inside the target DTML method.

That is, if you have check boxes or multiple select
form-input-elements, you would use something like:

<input type=checkbox name="mychoices:list" value="myvalue1">
...
<select name="mychoices:list" multiple>
<option>
...

Inside DTML, you would just use the name "mychoices" without
the colon. Something like:

  <dtml-in mychoices>
   <dtml-call "qryCAssign(user_id=_['sequence-item'],
                          client_id=client_id)">
  </dtml-in>

If qryCAssign() is a DTML method instead of an
external method, generally you would need to
prepend (_.None, _,... ) to the argument list.
That is, qryCAssign(_.None, _, user_id=.......)

Stable and functional.  It is being tested on several projects.

No.  These are very deep issues, especially the replication part.  If
this is important to you, I suggest using a replicated filesystem to
store the final FileStorage file, like Coda or Intermetzo.

While it would be a great idea for there to be failover and replication,
the issues are complex and without more wide spread use we really don't
want to start engineering a solution (one of the reasons we are open
sourcing it...)

IE will show a cached page, regardless of the settings, when hitting the back button.
If you were to type in the URL, it might actually get the page, but you can never be
too sure with IE.  Its cache is terribly misbehaved.  Try making the page uncacheable
with a Cache-Control: no-cache header.  To verify if this is the problem, hit
ctl-reload in IE (shift-reload in netscape) to force a reload of the page.

This should work (untested):

Some sort of transaction log would be nice. Not only could you track this

on my part.

Paul teased greatly last week with his announcement about a BIG
announcement he was going to make at BALUG. I was going to be out for the
day and not able to keep up with the mail but before I left I checked mail
hoping there would be news as to what it was. Alas no such fortune.

I get back and WOW! This is absolutely tremendous news.
Major, major thanks to all at DC, especially those that pulled the trigger.

I agree that this does set Zope apart from the others. It also set DC apart
from the others in their willingness to do a very good thing.

May DC be greatly blessed and prosper mightily because of the gracious
giving and contributions to the best open source web platform out there.
Once again mucho gracias.

This should be fairly easy to do by creating an external method that calls your
program, then calling the external method using dtml.

Just to nitpick, that isn't true. Zope object ids can contain periods, but it
makes it a pain to refer to those objects in Python expressions. -jfarr

Just for the record, I dont' use FastCGI and have seen Zope
die under the same circumstances; ie. by disconnecting the 
browser mid-download of a (usually long) page. Fortunately, 
that 'client' has been me via the administration screens, 
but it does seem like a rather trivial DoS. 
But it seems that this only happens with certain types of
pages - I'm not sure which.

Unfortunately, I can't remember if this was when we were using 
PCGI or Proxy-Pass, but it was definitely one of the two.

Hearing that others are now experiencing the same gives me
hope: this could explain the crashes that we've been plagued
with for months (though I fear any solution will come too late
to prevent our switch to an alternative platform).
 
chas

ps. Weird thing : the most stable Zope installation I have
    is on NT. It never, ever crashes, despite being the 
    development machine (I wouldn't say that load is causing
    my production server to die b/c it happens under low load
    too).

It seems that a lot of sites (including mine) have problems with Zope's
stability but somehow not many people reported the problems, and I am not
sure whether DC was/is aware of them. Our most useful Zope component right
now is a script that checks our Zope server every 5 minutes and restarts
it if it is down. I have spend many hours debuging but I failed to find
anything sustantial. I am under the impression (but nothing more solid)
that one problem might involve the interaction of the select call and
signal handling or the python wrap around the select call. No proofs
though. Unfortunately like you I failed to convince people in my group to
use Zope for more ambitious projects because of the stability problem.

It may also be due to people using the ZopeMonitor on Unix, which
restarts Zope if it dies.

Even better, it is a part of Zope! :)
From z2.py:
========================================

  -Z path
    Unix only! This option is ignored on windows.
    If this option is specified, a separate managemnt process will
    be created that restarts Zope after a shutdown (or crash).
    The path must point to a pid file that the process will record its
    process id in. The path may be relative, in which case it will be
    relative to the Zope location.
    To prevent use of a separate management process, provide an
    empty string: -Z ''
===========================================

Basically, add the option, along with the requisite options, and there
you go.

the problem is not in your query-code, i guess ..

IIRC, the catalog-aware zclasses are indexed automagically
when created, but not properties you set after creation. So
when you search for track_hasfile='on' , Zcatalog doesn't
have that property indexed:

You'll have to add :
<dtml-call reindex_object> in your Zclass Constructor method
( if you change properties there)

like this :

<dtml-with "Zclass_name.createInObjectManager(REQUEST['id'], REQUEST)">
       <dtml-call "propertysheets.Propertyshhet_name.manage_editProperties(REQUEST)">
       <dtml-call reindex_object>
</dtml-with>

-
Another possibility could be that you haven't added
track_hasfile to your indexes in Zcatalog.
If it is just a on/off-flag (which it looks like from here)
, add it as a field-index..


For better information, check out the excellent Zcatalog /
catalogAware HowTos on zope.org..

try

                relation='uncle'>

When you use the double quotation mark, it processes the content between
the double quotes as python code to be executed.  Since there is no
python code called bob, it fails.  Putting single quotes treats the
value as a string.

Hi there,

Thanks all for your help.
I got it working by keeping my old configuration in the ODBC Control
Panel settings and using 
'gsmInfo testowner PASSWORD' as the connect string in Zope.

Cheers,

Hi,

A simple question, but getting a bit irritating...

How can I change the roles assigned to a user without knowing their password?

The form to do this has password fields which come up blank, and you can't submit the form without
filling them in.

I don't want to know what the user's password is anyway, I just want to change the assigned roles...
;-)

HSCH,

Subject: [Zope] Using a database connection from an external method
Message-ID: <38D9F99C.726D6D4C@funcom.com>

I'm still figuring out how to integrate stuff in and out of Zope, and
thanks to all the people who gave me the friendly advice that I should
stay away from storing blobs in databases (I kind of knew that already,
but guess I was to busy worrying about marshalling things in and out of
Zope).

Anyway, what I am trying to do now is create an external method that
will receive the REQUEST object with some fields AND the uploaded file.
This external method will insert a record into an SQL table and return a
unique ID which I will use for the filename for storing the image in the
local filesystem (I am not worried about LOTS of images in a single
directory - that can be solved by a more intelligent filesystem
[ReiserFS?] or by some clever directory indexing).

Assuming I am able to pull this off, it should be quite easy to pull the
image back in again using the LocalFS product or my own external method.

I guess the external method will be run in the same process and thread
as the Zope process itself, so I would really like to get hold of the
database connection from my database connection instance in Zope. 

From searching the lists, I have learned:

* How to get the ZODB instance using self._p_jar; but this is not what I
need. I need to get the database object for my MySQL database, not ZODB
* How to call ZSQL methods from external methods by simply doing
self.someZSQLmethod

The last method would probably work, but since adding something to my
database table really consists of a database insert, then getting the
unique ID returned and using this for stuffing an image into the local
filesystem, I would prefer to keep this all in the same External method.

So the question then is:

How can I obtain the database connection to the external database (the
"Z MySQL Database Connection" in my case)? And I do not mean the
connection to ZODB.

Thanks,

Marius Kjeldahl

You can specify ":list" in your checkbox code to typecast the input.

Here is a quick test. The list should display OK when one checkbox is checked.

<FORM method="post">
<INPUT type="checkbox" name="myList:list" value="First">First<BR>
<INPUT type="checkbox" name="myList:list" value="Second">Second<BR>

<dtml-if btOK>
  <dtml-if myList>

   </SELECT>
  </dtml-if>

This creates a user from python - nice, but doesn't solve my problem. I want
to be able to assign a property sheet of some sort to each user I create, so
I can store his/her local preferences on my site.

Does anybody have a clue on how to accomplish this?

Thanks for the suggestion, though.

Message-ID: <38DA05CD.7F089CCC@nipltd.com>

Hi,

I was thinking about putting my 'Changing Roles' problem into the collector as either a bug or a
feature request so I went and had a look.

It's REALLY hard to try and find out whether anyone else has done this before.
Not only is there not any real categorization of bugs/featrues within Zope (everything seems to be
'General') but neither the search or advanced search is documented.

Most irritating though was that it doesn't look like you can read problems unless they're been
solved, so although there were a couple of bug titles which looked like they could be what I was
talking about, they were all ***This item is under review*** so I couldn't check.

By all means flame me if I'm being stupid, but otherwise coudl someone help me out?

cheers,

Chris

Actually dots are allowed in object names. You can create a picture called 
"myPic.jpg" and insert it with <dtml-var myPic.jpg>.

However because of their special meaning in Python they make it more 
difficult to access objects in Python expressions from DTML.

Example, to access the picture title, you'd need to use :

<dtml-var "_['myPic.jpg'].title">

or (simpler but longer)

<dtml-with myPic.jpg>
    <dtml-var title>
</dtml-with>

Subject: [Zope] Roles, Local Roles, and so on


Hi,

I have a question concerning the Role and Local Role system. Well, am I
right
with the observation, that Local Roles are only locally assigned global
roles?
For example I have an user "oandrich" which is globally just a member of
Role
"user" but in /test/users/andrich for example I can assign him a "Manager"
role?

Isn't it possible to get really local roles? What I like to have are roles
that needn't be defined in a global context and which are only available
below
a certain directory and are local to this part of the directory tree.

Some background why I need this. I am developing a problem tracking system,
that is used in my company, but we also of companies that are subproviders
of
us. I like to do the following.

In

    /rz-online

I install the tracking system for us.

In

    /ewr-online

I install the tracking system for one subprovider.

Well, when I have to define global roles I see the roles the ewr-online
admin
defines in my possible list of Roles. And he sees mine. Ok, for me this is
no
problem, but the ewr-online people are a little bit nuts and so this will
certainly confuse them.

Ok, I can do something like adding global roles named like this

    JTS_<id of the folder>_<desired name>

This is easy and fine to do in Zope, but it is ugly. So, is it possible to
get
really local roles?

Bye, Oliver


[RH]Oliver,

the current role system lets you assign roles from a certain object (you can
add them under the security tab).

You could also devise a method or a product that (manually) registers the
roles a user is entitled to (or already has, depending on the situation),
but that could get you turning in circles easily.

Rik

Would it work for you to create a folder for each user with id same as the
username?
You get a propertysheet with the folder for free. You could also make good use
of acquisition to display pages based on preferences.

The easiest option is simply to wait a bit til the PTK version is working. 
Or even help out yourself with this part of the code.  Otherwise, you can,
for example, create an SQL table (in gadfly) with the username as an unique
index and properties as other columns.

Okay, I've put this into the collector now (hence my complaints about the collector ;-)

I've got a proposal:

How about leaving the form as is, but if the password fields are blank, then don't change the user's
password?

I might have a look at coding this later today.

If I do, how do I get it into the CVS or back to DC in some other way that it'll make it into the
next Zope point release?

cheers,

I am not in a position to go into a testing program in mid-april,
however I think there are probably many of us who wouldn't or don't
currently qualify who would simply like observer status on a mailing
list or something. That way we can at least begin the learning process.
It also puts more eyes on the problem.

Your question addresses a fundamental lack in Zope.  Zope was developed
internally in a closed source fasion for years to address the needs of
paying customers.  These customers typically did not design applications
themselves, we did all of that.  Therefore, much of Zope's API is fairly
oriented toward specific directions and there are big gaping holes.

Don't let that discourage, you, there are big gaping holes in all
software.  We are working on a project right now to come up with a solid
undertanding of interfaces in Zope.  While this may seem like a simple
task, it is not, but we are working on it and we are making progress. 
Here, you have come upon a hole, there is a method that lets you do a
number of things in one call but there are no decomposed methods that
let you do finer grained tasks.  This kind of situation is common, not
just in Zope, but in lots of software where extensability is very
important.

Unfortunatly, this is a gnarly problem.  For example, if we decompose
manage_users() into a number of smaller methods, it would make sense for
us to re-implement manage_users() to use those methods.  But this
involves not only writing a bunch of new methods but also taking solid
proven code and discarding it for new code, based on even _newer_ code. 
This problem becomes almost nauseatingly dificult when you consider that
we could turn this process to all objects in Zope, Folders,
ObjectManagers, ZCatalogs... And while it may seem clear there should be
so and so methods to decompose to, we need to make sure we think hard
about issues like, should they be callable via XML-RPC?  Will this new
method reveal a security exploit?  etc...

I don't want to take the wind out of your sails, perhaps you could
suggest some improvments, all the code is there.  For now we are taking
small steps, document what is there, propose a framework for sensible
extension, and then fill in some of the gaps, and tear down some of the
cruft.  I will make a note of your question for when we get to security.

I totally agree, don't worry... no wind taken out of any sails ;-)

After all, Zope is free and there are plenty of (very) expensive alternatives that will have just
the same sort of problems.

Hope I can help at some stage :-)

Aye carumba, I haven't even been following this thread, not the most
useful subject line!

Ok, it looks like there are two issues:

1) some sort of FCGI issue which I do not have the capacity to reproduce

2) the same stability issue I am currently looking into.

The problem with 2) is that no one can reproduce it reliably (this may
not be true after I look at something someone sent me today, I'll keep
everyone updated) including myself.  I have pounded a half dozen
sandboxes with ab for hours and gotten nowhere.  No crashes.  Not a
single burp.

I'm, of course still looking into this, but I need more data from the
folks out there.

First of all, if you suspect that your Zope is dying and restarting
alot, run it in debug mode like this (unix only, sorry):

bash$ strace -f -e trace=none -signal=all python z2.py -D

See 'man strace' for the gory details.

obviously tune the parameters to z2.py to suite your needs.

What we are looking for here are SIGSEGV.  You'll probably see a lot of
SIGUSR1s, these are normal.

If you can get a SIGSEGV to happen reliably, _please_ let me know.

You'll have to roll your own form, and have it call manage_users on the user
object with the variable 'remote_user_mode__=1'.  For example::

 
<URL:http://server:8080/acl_users/manage_users?name=fred&submit=Edit&remote_user_mode__=1>

suppreses the password display (but it is still there in hidden input field!)

You aren't being stupid at all.  Here is the low-down on the Collector:

 * New items in the collector are immediately marked "under review" 

 * "Under review" issues can't be viewed until they get marked "in work"
   or some such, allowing submission of security-sensitive bugs without
   publicizing them to "black hats."

 * Most issues sit in the "under review" state far longer than the minimum
   time to triage out the security bugs; this is a lamentable corrollary to
   DC's short-handedness.

Fixing this problem would require adding to the Collector a new state,
"submitted", which then becomes the "show no details to black hats" state, and
sending off nightly emails of "submitted" bugs to the sucker^H^H^H^H^Hteam
member responsible for the Collector.  Moving the bug to "under review" should
then make it visible to outsiders in all its glory.

Hello everybody!

Please join me in welcoming Matt Burleigh to the Digital Creations
team!!

Matt joins us as our first (and sorely needed!) system administrator.

From Matt's man page:
"""
I call beautiful and historic Fredericksburg, Virginia my /home.
Fishing, hunting, and reading civil war history are my hobbies.  Don't
tell anyone but I've taken many tech support calls from a boat and even
lost a cell phone in the lake once.

In 1983 I got a 1200 baud modem for my 64k IBM PC and it was down hill
from there. Sometimes I feel like I spent all of my life in front of a
computer. I started the first BBS in the Fredericksburg area and a quite
successful one. Eventually becoming Central Virginia mail hub for
FidoNET and sucking Usenet newsgroup feeds off of a satellite dish then
divvying it up for the local area SysOps. Those Usenet feeds were from
this thing called the Internet, which took me by suprise in 1994. At the
time I was running a small computer sales and service shop in the area.

Once I realized that BBS's and RIP Script (a graphical language for
BBS's that was going revolutionize the online world, ha!) wasn't going
to make it, we switched our dial-up modems to direct connections to
ISPs.

In 1996 a friend of mine introduced me to Slackware Linux. This crude
operating system really intrigued me and I found it to be an exciting
new challenge. A couple months later I began selling used machines with
IP masquerading and firewall setups. Soon after that, I convinced a
customer of mine to switch from the ever failing Windows NT v3.51 to
Linux. The system ran for over 6 months with not one problem or required
reboot. I was hooked and swore never to install Windows NT again.
"""

You could try:
<dtml-call "RESPONSE.expireCookie('main_counter'">

which might work.

Hello all:

Not sure if this has been asked before, probably yes, but haven't been

Does any of you has been able to print from a Zope application to a
printer attached to the same machine where Zope is running, in my case
it's a Red Hat Linux 6.1 box.

I need to print from Zope with a specific printing format (like
invoices, receipts, etc).  This will be done on always the same Intranet
and printing will be controlled from the Linux spooling system.

If you can copy your comments to me by email besides the mail list, it'd
be great.

,Any help is appreciated, thanks in advance.

I am not usre what you need to do. The cookie name is SassionUID. If you
need to delete something from the FSSession data use FSSession.delete
like:

<dtml-call "FSSession.delete('main_counter')">

you can expire the cookie by ... reading Chris followup email (just

Message-ID: <Pine.LNX.3.96.1000323155356.11696K-100000@marvin.nipltd.com>

My saga with the standard_error_message continues ;-)

I'm trapping 404 errors for missing pages, checking the intended URL
against a list of URLs which have moved to new locations and returning a
link to the new location as part of the error page.

What would be useful would be to automatically redirect to a new URL if
it occurs, but this is proving a problem. I've been using
RESPONSE.redirect() as this has proved useful on other pages, but on
standard_error_message this doesn't appear to have any effect - even when
the entire contents of the error page is stripped out and replaced by just
the call to redirect().

Is it possible for standard_error_message to handle redirects (in which
case, what else do I need to do?) or is there another way to go about
this?


Thanks in advance.

John

Subject: [Zope] records form variable type
Message-ID: <wksnxh8xai.fsf@email.aston.ac.uk>

I have been using the records form variable type, but believe there
may be a problem with it. With most browsers all appears OK, however some
browsers (e.g. Mozilla) may return form elements out of order. What
this means is that when trying to use the records type their is no
guarantee that the different elements of a single record will be sent
consecutively and therefore the records objects will not be correctly
constructed by Zope.

I would like to know if this is the fault of browser or if this is an
issue which excludes the general use of the records type. If the
latter what alternatives would be recommended - I would prefer not to
have to create unique form element names as it would add a fair amount
of complication. 


What guarantees can be safely assumed about data arriving from a form
- for example if you try using the list type is the order in which the
components of the list guaranteed to be the same as the order in which
the respective form elements occur in the document?

Subject: [Zope] timing error in ZODB lock?
Message-ID: <38DA468F.898A2FFB@sage.att.com>

i'm getting some funny behavior using a (separate from Zope's)
ZODB from External Methods.  after much thrashing, i've got my
application working.  however, every so often, when i click 
on a submit button that invokes an External Method, i get:

   Could not lock the database file. There must be another process
   that has opened the file. 

the odd thing is that if i click the browser "back" button, then
hit my button again, it works.  occasionally i need do this
back/resubmit thing more than once, but usually once suffices.

smells like a race condition to me.
has anyone else seen this, or have an idea how i can avoid it?

http://www.reportlab.com/ may be what you need.  It's in Python, so it
should be easy to hook up to Zope, and it outputs PDF which can then be sent
to lpr for printing.  Since RH uses Ghostscript as a print driver the
generated docs should print fine.

I would favor making it like the HowTo list; where you can organize by
title, date, author, and reverse them. The code should be a basic

Just wondering if anyone has thought about personalization
services based on Zope ? 

The most obvious/traditional approach seems to be :
1. Acquire user information (via forms/surveys/transaction-histories etc)
   and store in RDB. 
2. When the user comes to the site (and either logs in or is identified 
   by IP or cookie), query the RDB for customized content or appropriate
   products. 

OK, no magic there. But it's not very scalable in terms of :
a) Load. We can keep shoving Zope servers on the front end
   but the RDB is going to get hammered if this has to occur
   for each and every request. 
b) Development. A more object-oriented approach would be nicer.
   eg. Personalities with behaviours and properties. 
   Could a pool of persistent personalities be left floating 
   around ? (No, this is not an early April's fool) 

A while back (1997) I saw Broadvision and didn't really appreciate
what they were doing. It seems that they've really improved a lot
since then but I can't get my hands on their software (not for free
anyway). So, I'm wondering if anybody has experience with it and 
can enlighten a heathen on key features we might wish to, er, 
'appropriate' in Zope systems ?  Or is it, like Vignette and Netscape
ECXpert, nothing special and you're basically paying for the 'knowhow' ? 

Thank you,

Message-ID: <002b01bf94e6$968a7af0$f2381bd8@LIPS>

hello:

i'm using Zope 2.1.6 and LocalFS 0.1.7.  when i try to view an image via a
LocalFS object i get an exception in OFS.Image.py at line 187:

last_mod =int(self._p_mtime)

the error occurs the *first* time i try to access a specific image with a
recently launched browser.  accessing other images or subsequent hits to the
troublesome image in the same browser do not cause the problem.  subsequent
hits in the same launch of zope from a fresh browser on another machine
causes the exception.

having modified Image.py to catch the exception and dump some information i
see that self._p_mtime is None.  i've looked around but cannot determine
where _p_mtime is defined or how it is supposed to be set.

i see this method in Image was re-written after Zope 2.1.4.

similarly, accessing a .wav file via LocalFS causes the following message:

2000-03-23T16:27:13 ERROR(200) ZServer uncaptured python exception, closing

the wav file is delivered to the browser correctly.

as a quick fix to the Image problem, i catch the exception, set last_mod =
0, and continue.  this does not seem to have any ill effects.

Subject: [Zope] ZWiki comments
Message-ID: <38DA502B.B20E8928@texoma.net>

For a previous message I posted to the list I was prompted to place a
comment in the associated ZWiki.

I went to the ZWiki to comment and played with the "Sandbox" before
posting to learn a few things. From the things I learned here are a
couple of comments I wanted to throw out. I know some of these run
counter to the thoughts of the Wiki community but they are concerns
nevertheless.

The nature of Wiki is very unsecured. This is for better or worse. I
know the ZWiki on the Zope site does require logging in before editing
which helps but does not eliminate the potential of malicious or
accidental editing.

Anyone logged in can do any kind of editing they wish on a page. They
can erase all text. They can insert, delete or otherwise modify comments
or content made by other people. These things can be positive or
negative depending on the goal or intent of the page.

I think editing a page is more applicable to stable open content than it
is to a forum oriented page.

Examples.

If Zope's documentation was managed by ZWiki in a secure manner then a
community member could make corrections of typo's or legacy information
like references to Principia, etc. The submit button could either be a
"Submit for review" or if really trusted "Change". I know this
duplicates somewhat what CVS does. Once again depends on goals.

If the page is forum oriented, i.e.: an on going conversation like a
bulletin board and such then it is more appropriate to "Add comment"
than to "Change page". This would present the user with a cleaner
interface and a clearer idea of what they are doing. They would not be
presented with the entire contents of a page so they could merely append
a comment on the end.


If the ZWiki on the Zope site starts getting busy we run into other
problems. The problems especially affect a forum oriented type page.
Just to learn I opened up the "Sandbox" in a new page, I then open the
"Sandbox" again in a new page. I edited the first and submitted and then
edited the second and submitted. The first was successful. The second
fortunately got an error message. I say fortunately because it did not
overwrite the previous submission.

In a busy forum or BBoard multiple people getting errors would be a bad
thing. If in a forum oriented page an "Add comment" button was available
then the conflicts and errors would be avoided. This would also enable
ZODB's transaction mechanism better with each comment being an object
associated with the page.

This would also be more secure in that people would adding their value
and not altering other peoples.

On Philip Greenspun's site  http://www.photo.net  the BBoard's are
somewhat integrated with email. You can subscribe to a bboard and
receive email for the added comments. This is a nice feature. Their
implementation is quite inelegant and could be improved. Zope/ZWiki
could shine here. This allows user to choose how they want to view the
messages, either through the web or via email.

Just a few thoughts to throw out to the community.

Actuatly, there may be one other quicker method to do this.  You can somehow
(i haven't tried this) compile php into a stand alown executable.  Then you
could then have an external method do a shell call running the php script.
Another interesting thing you could do would be to make a zope product that
stored php3 code, and then called out to php to parse it.  This might not be
a bad way to allow clients to have their own maintainable php3 scripts up
on the web without giving them ftp or shell access.  hmm..

I was thinking of a general simple caching product for Zope, to use in
conjuction with FSSession for high load sites. A simple implementation is
to use an in memory python dictionary to hold marshalled or cPickled data.
Since the access times are fast we could use the asyncore classes that
come with python to achieve really high rates. The cache contents can be
served from a socket or a named pipe. A more difficult but more efficient
way is to use shared memory for IPC. As I don't expect two clients to
connect simultaneously with the same user id, write conflicts will be few
(I suppose writes will be few too).

In our environment I have found FSSession to be very fast, probably
because the OS caches files. If someone complains about FSSession's speed
I will code the caching product.

On Zope, I created a new ZClass, EBook which is Subclassing, CatalogAware,

I created an instance of EBook which id is 'aid' in a Folder called 'new_test'.
It works fine in Zope except I cannot use my writeData method of my EBook
class because of the following error:

I work with Linux and all users have the right to write in /home/oscar/data'.
I even tried to run the method from the interpreter, just changin
f.write(self.data) to f.write('arbitrary string') and it works fine.

**Can you tell me where am I wrong?**

I also tried to use the debugger to understand where I am wrong.

Or even better, a generalized version - so you could serve perl and php and
python cgi  scripts transparently from zope.  That's be pretty cool actually
- migrating our old sites from php to Zope would be trivial.  

Of course, it'd be much slower than having PHP3 compiled in to Apache.

Subject: [Zope] ZEO app architecture options
Message-ID: <38DA5AD1.EE6A264B@texoma.net>

Hello,

In light of ZEO becoming open source, I'm still extremely excited, I
want to revisit some questions I threw out in a previous thread about
Zope's scalability.

Can I architect a website like this using different Zope Storage Servers
for the various directories or 'would be' tables in an RDBMS? Yes, I
understand the impact of the OS filesystem concerning ZODB size.

Say for example I have a large database. Like this:

ZAuto
ZAuto/parts/
ZAuto/manufacturers/
ZAuto/distributors/
ZAuto/distributors/...(orders, address, preferences, etc.)
ZAuto/resellers/...(orders, address, preferences, etc.)
...

Let's say that ZAuto/parts is a 5+gb directory which is reasonably
stable updated monthly.
ZAuto/manufacturers isn't as large but is also stable with periodic
updates.
ZAuto/distributors and ZAuto/resellers are much more dynamic with
changes and additions.

ZAuto/parts could be optimized for search performance. It only needs to
be backed up periodically when bulk changes are made. It will relatively
almost never need packed. It could sit on it's own drive, own machine,
etc.

It would be nice to be able to partition the database into
stable/volatile files. Since the stable partition is also the largest,
it seems this would also help performance of the more dynamic section.


Also, when comments are made about Zope's ZODB or ZSS not being
appropriate for heavy write apps, does this refer to apps doing
"updates" on objects or doing "inserts" or both using SQL terminology?

Would structuring an app like above help in write situations?

I am trying to determine the desirability or necessity of an RDBMS for
my idea. I like keeping it in Zope if reasonable and ZEO can definitely
help. If need be I'll go to an RDBMS for certain data.

Thanks for any help or clues.

As much as I appreciate the desire to get at ZEO early, we have to
balance that with our limited resources internally.  We're taking a
conservative approach to getting it out the door, rather than just
dumping code and telling people they're on their own.

Hopefully everyone can appreciate this.  Unfortunately we're taking a
lot of flak, for instance, for not releasing Tracker.  I wish we had
unlimited resources, but that's just not the case.  As everyone in the
Zope community will probably agree, we need to do a better job and not a
bigger job.

This isn't necessarily true.  Zope caches objects, and the scenario you
describe is well suited to the caching strategy.  (That is, a user is
probably going to come back again within a minute of their previous
request.)

Compare this to an RDBMS strategy where state is always being retrieved
on each request.

The PTK membership model allows arbitrary extension of methods and
attributes.

Sorry, I forgot that I hadn't uploaded the text of the FAQ.  My network
connection was horrible yesterday (I'm in a hotel in the Bay Area right

You'll need to write some software in Python that will interface with
Zope for printing to your local Linux printer. In general, this isn't
something one would normally go about doing.

Now I just get "You don't have permission to access /Zope/home on this server." no login prompts start screens or anything.

Is there anyway of debugging the interaction between Zope and Apache rewrite?

Why not use something like SWIG (I don't know much about it, just a general
idea on what it does), to link the interpreter to python, and then make a
Zope extension like <dtml-perl xxx> to call it? Then you could probably get
the perl/PHP scripts into the ZODB, and therefore get cached, making it even
faster..

i think you need to set permissions to execute cgis within that
section, ie. put

Options ExecCGI

into your <VirtualHost></VirtualHost> section

Subject: [Zope] Troubles with SQL queries
Message-ID: <Pine.LNX.4.10.10003231313390.10023-100000@odeon.net>

Heya folks,

I've got an SQL query that looks like the following:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.date, gigs.start_time

This works fine.  The '/'s indicate that a single line continues, in the
ZSQL method the 'and gigs.date >= etc." part is on one line.

I'd link to be able to change the values the query is ordered by based on
the link used to access it.  Something like the following:

http://foo.bar.com/Zope/query?first=date&second=start_time

Towards that end I made the above look like:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "<dtml-call "REQUEST.set /
    ('CurrentDate',ZopeTime().Date())">  /
    <dtml-var "REQUEST.CurrentDate">"
  order by gigs.<dtml-sqlvar first type=string>, /
    gigs.<dtml-sqlvar second type=string>

When I test the ZSQL method it shows the SQL used as:

select artists.hidden_URL,gigs.*
  from artists,gigs
  where artists.name=gigs.name
  and gigs.date >= "2000/03/23"
  order by gigs.'date', gigs.'start_time'

Note the 'date' and 'start_time'...  Because of the 's the query does not
work.  

Is there a way to not have the <dtml-sqlvar> tag return the 's to MySQL,
or is there another way I should be trying to do this?

Thanks for the help,

Jeff Robertson

Subject: [Zope] How do I pass parms past a redirect?
Message-ID: <38DA80A9.411DFC15@sage.att.com>

i'm building an app that requires me to connect to another
server in the company to do employee authentication.
one connects to that site, passing a return URL.
it verifies the employee, sets a cookie, and redirects
to the URL you gave it.

so, in a document i want to protect, say, ChangePerson.dtml,
i've got something like:

<dtml-if "REQUEST.cookies.has_key( 'attESSec' )">

	...regular actions for the page...

	<dtml-call "RESPONSE.expireCookie( 'attESSec' )">
<dtml-else>
	Missing attESSec cookie!
	<dtml-call "RESPONSE.redirect(
'http://othersite/cgi-bin/authenticate?retURL=http://mysite:8080/ChangePerson&sysName=foo'
)">
</dtml-if>

note that the URL i redirect to expects two parameters,
retURL says where to return, and
sysName is an application name given when
i registered to use their services.

so far, so good.  the problem is, my document expects to be
called with some parameters passed, like:

	<a href=ChangePerson?hrid=1234567&name=garry>Change</a>

now, i can't encode these parameters in the retURL
i pass the other site, as i get a "malformed syntax" error.

so, my question is, how do i make this information available
to my script on the return?  do i set a variable in the container?
set a cookie?  or is there some better way?

to broaden a bit, how does one pass information around in general?
so far, i see several methods, for calling:

External Method: piece of cake.  real live arglists, like god intended.
DMTL Doc from form: form variables, mixing hidden vars in for other
stuff.
HTML links: cgi-style syntax, leads to ugly URLs.

is this the right way to do things, or am i missing something?

Subject: [Zope] xmlrpc authentication woes
Message-ID: <38DA8147.3E2F3325@boi.hp.com>

First, let me say I have patched my xmlrpclib.py to support
authentication; that isn't the problem.

Overview:
I have a folder, 'Administration', which requires manager login to
access. In this folder is a subfolder called 'MachineTracker'. In this
folder is a collection of ZSQl Methods, DTML Methods, and DTML
Documents. What I want to do is to connect to the server via XML-RPC,
and make use of the ZSQL Method for inserting data into the database.

Problem:
When attempting this from python in XML-RPC, I get a 401 Unauthorized
error. I can access the folder, and other methods, such as index_html()
and objectIds() with no authentication issues. 

Any ideas?

(please cc me here, this isn't my subscribed address)
TIA, Bill

 You can use one of the Session products (SQLSession or FSSession) to
store arbitrary per session info (even Zope objects) on the server. It is
probably the cleanest solution.

Use the handy dandy Python range operator (generates a list of ascending

<dtml-in "_.range(noOfTimes)">
  <input type="text" name="...

A simple question, how can I determine the Owner
of a ZClass instance (or any Zope object for that matter)?

My users create instances of a Seminar ZClass.  I did not
create a SubmittedBy property (which I would fill from
AUTHENTICATED_USER.getUserName()) thinking that I could
easily extract this from the Owner role.  I just can't
see how to do it.

I have run into this problem before.  Floating about on the ZOPE site is a
patch for the MIMETools, which addes a few *_expr attributes, so you can replace

name="_['file.filename']"

with:

name_expr="_['file.filename]"

I have just written my own tag product (may or may not be allowed to release..
we'll see :)  I understand now why this is so.  It seems that, so far as the
product is concerned, there is no real way to tell the difference between a
string and an expression.

If I am mistaken, I would dearly LOVE someone to point me in the right
direction.  I currently distinguish vars and strings by if they have 's around
them, and expressions are attrib_expr.

But I digress.... the patch is your friend.. It is on the ZOPE site (sorry I
can't be more specific, but a quick search will find it.)  I have used it
myself, and know it works.

Message-ID: <000f01bf9521$065bc480$2aac8ec6@hikari.anu.edu.au>

I have a container ZClass Person.  Person has a (string) property
CurrentPosition which gives the id of a ZClass instance contained
in Person.  Example:

   DarranEdmundson (Person)
       bsc_degree (Degree)
       phd_degree (Degree)
       fellow     (Academic)
       fujitsu    (employment)
       vizlab     (employment)

where DarranEdmundson.CurrentPosition = "vizlab"


I am having problems accessing the CurrentPosition object
in a pythonMethod.

list = []
for person in self.objectValues('Person'):
     position = _.getitem(person.CurrentPosition)
     list.append(person.LastName, position.anyProperty))


I can do it in DTML via

<dtml-in "objectValues('Person')">
<dtml-with "_.getitem(CurrentPosition)">
   <dtml-var LastName> <dtml-var anyProperty>
</dtml-with>
</dtml-in>

I think the question really comes down to: how does one
achieve <dtml-with name> in a pythonMethod?

Darran.

Subject: [Zope] how to get the fields returned SQL method
Message-ID: <86ln39meyg.fsf@marcelle.revolink.com>

Hello,

I'm trying to get a list of fields returned by a dynamic SQL query.
I've found a howto telling me to write something like :
	<dtml-in SQL.names>
	<dtml-var sequence-item>
	</dtml-in>
But it doesn't work : I get the error "Attribute Error : names".
I've tried with .items, .keys and .fields too.

I'd like to do the same for an LDAP query.


Any idea ? I think it's very useful and that an easy way exists but I
can't find it.


Thanks,

EB.

OK, so I read the Advanced Catalog Search HowTo, and I am left with
a couple of questions.  I'm concerned here with "or"ing the searches
on two fields.  The first question is, once I do the OR is the
result (which may be close to a thousand records) cached?  Otherwise
I don't think this is going to work.  Even if it is cached, I'm
thinking it may not work.  Is there any way to do an OR without
loading both result sets into memory?

The other question is, when I do the OR, how do I reduce the
composed list to just unique records?  The HowTo seems to just
do a sequence join, which would leave me with duplicated records
for those items that matched on both search columns.

Well, since the SQL will return a list, firsly you would have to index it...
also, .keys et al are Python stuff, so...(untested)

<dtml-in "SQL[0].keys()">

might be more what you're looking for.  Or...

<dtml-in SQL>
  <dtml-in "keys()">
    <dtml-var sequence-item>
  </dtml-in>
</dtml-in>


should iterate through the keys of each line of the returned table.

ZEO is transparent to the application, it is a _singular storage_
meaning that all the issues of multiple databases still apply, re, they
are not yet supported.

What this needs is the ZDBF (Zope DataBase Framework).  This is a layer
that sits above ZODB.  Currently, ZODB takes care of all these issues
(or punts on them) when really a higher level abstraction should handle
multiple database issues (including any future extensions to the
Relational/Object model).  Obviously, this is a big task.  See paul's
email about resources. ;)

First, keep in mind that to a certain degree, all databases are
sensitive to the high-write issue.  ZODB is more sensitive because it's
conflict resolution is optimisitic.  FileStorage is also sensitive
because of the  inherent behavior of filesystems, and ZEO is sensitive
because for every object written, an invalidation message must be sent
to all other ZEOs so that they are given the chance to invalidate the
object in their cache.  This also increases chances of collisions
because the Time To Write a record is extended for varous reasons
(network delay, invalidation delay, etc...).
 
> Would structuring an app like above help in write situations?

Not without ZDBF.  Multiple database support would allow you to use
different, less write sensitive storages like a RelationalStorage or a
BerkeleyStorage.

Do some benchmarks, ZODB is very fast if you are a little more clever
about how you change your objects.  If you need more write intensiveness
go relational.

One doesn't.  Instead one uses local variables, as you did with 'person'.
Your solution is almost complete, actually, and should work if you replace
'_.getitem(person.CurrentPosition)' with one of the following (I'm not sure
which, you'll need to experiment):

person[person.CurrentPosition]
getattr(person, person.CurrentPosition)
person.aq_acquire(person.CurrentPostion)

Sorry I can't be more specific.  In general, though, any place you would use
dtml-with in DTML, you set up a local variable in PythonMethods.

Cheers,

Evan @ 4-am & digicool

Message-ID: <200003240350.AA11082@rsphy9.anu.edu.au>

I recently took the site I have been developing online
and have been beta testing with several users.  I
have a problem which is preventing a user from
viewing his home page; any attempt I make to isolate
the problem hangs Zope, stops anyone accessing
my site, and requires a forced unix kill.

The user's page is:
   http://rsphysse.anu.edu.au/optics/people/jdl124

Users are implemented as a Person ZClass.  One
of their contained objects is a PublicationFolder
ZClass, itself a container class for Journal ZClass
instances.  So above:

optics (folder)
   people (folder)
      jdl124 (Person)
         publications (PublicationFolder)
             article1 (Journal)
             article2 (Journal)
                .
                .
             article69 (Journal)


jdl124's home page is dying when it tries to iterate
over the results from a search of the ZCatalog publicationCatalog.

The problem isn't in the publicationCatalog however, the following DTML snippet locks up my Zope completely:

<dtml-with jdl124>
<dtml-with publications>
<dtml-in "objectValues()">
    <dtml-var id><br>
</dtml-in>
</dtml-with>
</dtml-with>

I can deal with this during solo testing but my users' budding confidence in the system I have created
has been mildly rocked by this situation.  Needless to say, jdl124 is none too impressed.  Any help
you can offer is most appreciated.

Cheers,
Darran.

This is a bit odd.  I have some image objects that display fine in
IE 4, but in Netscape 4 I get a Zope error

Invalid Date-Time String
Tuesday, 29-Feb-00 17:53:59

The traceback ends with DateTime.py, line 848, in _parse.

Is this a Y2K-leap error, or is something else going on here?  I've
checked two of these images and in both cases the date it is
complaining about is on the 29th.

And why only Netscape 4 and not IE?

I think you want this, which (it claims) generates PDF documents within
zope.

http://yyy.zope.org/Members/gaaros/ZpdfDocument

Then you just print it however your clients are already printing.

--------------11C1869DF092DB44C388B170
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

Assuming you are just going to be using linux this shouldn't be _too_ hard.

You probably would want to firstly use the http client module in python
(not sure exactly what it is sorry). Which could download a html page which
is generated by Zope.

The with the html page you can make a system call to "html2ps temphtmlfile temppsfile;  lpr temppsfile -Pprinter". Python has the ability to simply call 
external program (i think it is os.system( ) ). Of course you could find/write
your own html->ps and printing code but when you already have html2ps and lpr
I wouldn't really bother.

Now if you wrap all that up into an external method which is called when the 
print button is pressed it should be quite acceptable.

Is this the type of thing you want or am I off in another planet?

Why not generate a PDF file on the local file system and then print it

just my 2 cents...

I think a translator should implemented using a flag in dtml-var:

syntax: <dtml-var VARIABLE translate> and <dtml-var VARIABLE 
translate="de"> for example.
Short form: &dtml.translate-VARIABLE;

By default it chooses the root folder's (or even Zope's?) language setting, 
but the programmer can also choose the language. This syntax is very 
similar to the "missing" flag. This way you do not a separate phrasebook 
and word translator. All that is in the background....

Then there is a generic translate product which handles all the translation 
stuff and administrates the languages. One can easily drop languages into 
the product, by installing simply the dictionary for this language into 
some standard location and specifying some admin info.
I think that would be the cleanest way to implement ZIP.

What do you guys think? Comments?

Stephan

I tried sticking <dtml-var get_local_roles> in a dtml document and got a blank list back even though
I know I've got some local roles.

Also, where did you find out about this? I haven't found it documented anywhere...

<dtml-var "AUTHENTICATED_USER.getRoles()"> is also not too useful since it only returns roles where
the user object is defined, ie no local roles...

What am I doing wrong?

References: <86ln39meyg.fsf@marcelle.revolink.com>

Okay, a lot depends on what your query is returning.

If 'names' is not the name of a column, then ignore the rest of this message ;-)

If it is, then try the following:
<dtml-in SQL>
 <dtml-var names><BR>
</dtml-in>

- If 'SQL' returns a single row and 'names' is a single-valued column, then it should display the
value of names.
- If 'SQL' returns multiple rows and 'names' is a single-valued column, then it should display the
value of names for each row returned on a seperate line.
- If names is a multi-valued column then you should get something like
  [...,...,...]
  for each row returned.

cheers,

Chris 


If names is a single-valued column then the following should work

I experienced this as well also on Netscape (but I didn't try with IE)

Did you create the images on Feb 29th? I think I did and made the problem go away by re-uploading
the images.

This is a bit of a worry though, anyone got any ideas what's going on?

Hi Chris

I wrote Amos for exactly the same thing and here is his answer:

...
This is a Zope error. I was working with a development version of Zope
which didn't have the error. The error is fixed in CVS and should ship
in the next release of Zope. To fix the error add this line near the top
of your lib/python/Products/ZCatalog/ZCatalog.py file.

from DocumentTemplate.DT_Util import Eval, expr_globals

Hmm, are you sure you're not trying to include python methods rather than DTML documents or DTML
methods?

Try:
<dtml-var "id()"> if there's not another reason why this isn't working...

Provided that ID contains a string representation of the id of the
document you want, this should do it:

<dtml-var "_[id]">

I hope I understood what you wanted to do, this may very well be
solving the wrong problem.

Hmm. That's not what happens for me. I get something like:

[('admin', ['Owner'])]

How do you know you've got some local roles? Also, is this a DTML document or
DTML method, because methods seem to acquire the roles from their container.

> Also, where did you find out about this? I haven't found it documented
anywhere...

It's all in AccessControl/Role.py.

IMO the documentation is just a good place to figure out where to start reading
the code. ;)

Is there any simple way to do this kind of things in

Subject: [Zope] error with ptk
Message-ID: <028801bf9584$2e178be0$722624d5@amazigh1>

I began to download and to install PTK's last version recently. I installed
the product by following procedure described in the file " Read Me ", and I
so obtained three new elements in the section products. But when I try to
create a new element "Portal", Zope sends back me an error. I search so the
details of the installed products and I notice that in the part " DemoPortal
" certain elements are broken:

It is a question of:
 . " DemoPortal / Portal "
 . " DemoPortal / PortalWizard "
 . " DemoPortal / Wizard "

In fact they are all the DemoPortal's ZClass which are lacking. Can it
involve a conflict with another product? Is it necessary to settle PTK on
Zope's clean version?

I work with:
Zope version: Zope 2.1.2 (binary release, python 1.5.2 , win32-x86) on Win
NT4 / sp4, as well as with Zope 2.1.4 on Linux Mandrake 7.0. (on whom I did
not test PTK because it is my working environment, and I do not wish to
pollute it).

Thank you for advices. I intervene only rarely. What is well , it is that
major subjects and basic questions were approached in depth, repeatedly,
what allows to avoid resting the same questions. By getting back this
information, the people of the ZDP make a formidable job. That has the taste
of object oriented thinking...

PS: In reality, the best way to learn Zope (IMHO) is to start with the guides
and then read the mailing list religiously.

The guides are at:

good luck, it is worth the effort ;-)

It doesn't work too. I can't understand why.
More general, I'd like to extract all the variables available in a
namespace (and if I can do it, I'll can get the list of the fields).

Hi,

I'd like to add, modify and delete entry in an LDAP directory. I've
quickly read ZLDAPConnection's source and I guess that fonctions
"_addEntry", "_deleteEntry" and "_modifyEntry" can do what I'm looking
for, but I can't imagine how ! :)
I've tried a LDAPlink.addEntry('dn','values') in a dtml-call. Apparently
it work, but there nothing new in the directory :(
Have you any ideas ?


Thanks,

Same suggestion. How it works (one possible way of doing it):

Using a standard Linux installation, create a document with your data in a
Python method and safe it as a local (temporary) file (e.g. using the PDF tools
that exist for Python, e.g. "PIDDLE"). Then just do the following in your Python
code:

import os
os.system('lpr /path/filename')

This works under Windows, too. Just replace the system call by something
appropriate like "copy path\filename lp1".

It should also be possible to redirect the stdout data stream directly to the
printing device. 

I have also found some more sophisticated solutions:

- using the classes wxPrinter and wxPrintout from the wxPython package
- for Windows: using the Printer API directly with
   import win32ui
   import win32com
   ... (gets complicated)

Hi,

Sorry, there are no book of Zope, yet. Many (I think) are comming.
You can also have a look at ZDP : zdp.zope.org

Hi All!

Now and then there are strange things going on with my Zope 2.1.4/Linux
Intel installation.
Ok, here is what happens:

http://www.myhost.de:8080

raises a Zope Error (Attribute Error, getUserObject)

http://www.myhost.de:8080/manage

requests authentication and I give as UID/pwd as the superuser's pwd.
Again, strange Error-Messages.

I repeat (non-deterministic number of times) this and suddenly: everything
is ok.

What can this be??

Regards, Ingo.

Eddie,

I seems from your traceback that the user you are using to
_run_ your Zope process does not have permission to read 
some (or all) of the Zope files from the filesystem:

> IOError: [Errno 13] Permission denied: 
> '/usr/local/bin/Zope-2.1.6-linux2-x86/lib/python/App/manage.dtml'

You need to make sure that either you run Zope as the same 
user you used to install it, or change the filesystem permissions 
so that the user you are using has read access to all of the 
Zope files (and write access to the /var directory and any files
in the /var directory).

Hope this helps!

Authentication is not your problem, the user your Zope is running as
does not have permission to read it's own files.  Keep in mind that if
you run Zope as root, Zope will automatically demote itself to the user
'nobody', this is a standard practice of many servers as running a
server as root can be a security hazard.  If you want to run Zope this
way, then make sure that 'nobody' can at least read everything, and can
write to the /var directory.  

Otherwise, run Zope as a user that can read its files.

So do I.  Several people have reported this bug, but I cannot reproduce
it.  No one has been able to reproduce it or tell me how to reproduce
it, therefore, I cannot fix it.  The only thing I can tell you is that
it has to do with ZClasses that catalog themselves and that it happens
rarely and that updating your catalog allways fixes it.  I suspect it
has to do with poorly engineered ZClasses.

The method that contains this code.  You are probably experiencing some

Message-ID: <00032409234800.00783@modemcable215.47-200-24.mtl.mc.videotron.net>

HI,

How to get information about a ZClass property sheet from outdside the ZClass?

The goal is to create a "myzclass_addForm" that generate automatically the
input fields for the ZClass propertysheets.

In tried this:
/Control_Panel/Products/MyProduct
	myzclass
	myzclass_addForm
	myzclass_addPermission
	myzclass_factory

I just modified "myzclass_addForm" to add:

<dtml-in "ebook.propertysheets.common.mypropertysheet.propertyMap()">

...stuff to generate the input for each property.... 

</dtml-in>

It worked fine when I called "myclass_addForm" by clicking on the "View" tab of
the myzclass_addForm management screen. However if I try to add a MyZClass
instance from anywhere in my Zope hierarchy, I get the following message:
"Authorization failed. Retry?" and if I cancel:

"Unauthorized

       You are not authorized to access common."

I tried to change permissions and proxy of my myzclass_addFrom but it doesn't
work.

Can someone be sweet enough to tell me where I could find docs on how to access
the propertysheets elements.

Thanks

Hopefully it will be up on /. today. Hope the Zope.org servers are ready.

There is also a Zope Discussion Board at DevShed (based on UBB) which is
pretty quiet now. It might be a place to get people learning about Zope who

Hi,

if you want to hide them based on permissions, this is easy. Set the "Access
content property" to the correct value and it works. This is the way I do it
for my application, where I have browseable admin area and a public area. If
    an admin logs in, he sees the admin area too.

If this is not the case, then do a 

<dtml-tree>
    <dtml-if "id=='x'">
        display as you like it
    </dtml-if>
</dtml-tree>

Bye, Oliver

I didn't create the images, but I would not surprised if they were
created then as there was a big push to get things uploaded before
the 1st.

I can have them reupload the images to work around the problem, but I
agree that it would be much better to know what the bug is.

I've implemented a variant of Michel's suggestion. Let me explain what I
am trying to do. I'm trying to implement the
SelfServeFAQ:www.lcg.org/ssfaq (SSF),written in php3, within my Zope
website. To give a consistent look to my site, I also want to wrap the
SSF with standard_html_header, etc. So when a visitor goes to
www.mysite.com/FAQ they are really being served
/SSF/directory/index.php3 wrapped with my Zope code.

The problems come when a user clicks on www.mysite.com/FAQ/add.php3 or
some such similar link in the HTML produced by index.php3. I tried using
mod_rewrite in Apache, but found that Zope used
www.mysite.com/FAQ/add.php3 as the base for all the links in the
wrapping code. The only way I found to avoid this was to use the "[R]"
flag in the Apache RewriteRule. 

But I want SSF to be transparent to the user so instead I used
SiteAccess to rewrite /FAQ/add.php3 to /FAQ and pass /FAQ/index_html the
script name "add.php3". index_html then uses lstaffor's How-To tip( use
"Client.call( www.mysite.com/SSF/directory/add.php3)[ 1 ]" ) to embed
the PHP script call in my Zope page. In addition, I wrote additional
code in my accessRule to pass images in the PHP directory tree via Zope.

There is one inconveniences with this approach: I had to hack SSF to
remove the <html> tags and some others returned by Client.call (it
worked otherwise but, hey, I want my HTML code to be clean). But all in
all, the resources of Zope (the code and the community around it)
allowed me to solve the problem with very little modification of the SSF
PHP directory tree contents.

If there is wider interest on this I could write a How-To on it.

Michel, I take back the assertion in my private email.

I've just determined that this glitch in my
CatalogAware Journal ZClass (using a custom catalog
as per http://www.zope.org/Members/AlexR/CatalogAware)
arises whenever a user edits an instance of this class.  

Users are using the standard Zope management interface 
but I have substituted the standard Properties View 
with an "Edit Journal" View.  This is a copy of the 
Journal_AddForm method (with default values culled from 
the now existing instance).

As per #4 in the above How-To, on submission this calls 
the following DTML method which puts my publicationCatalog 
in a strange state (requiring the update):

<html><body>

<dtml-call "propertysheets.Properties.manage_changeProperties(REQUEST)">
<dtml-call reindex_object>
<p>Changes saved.</p>

</body></html>

I desperately need to sort this out before users start
making changes.  I certainly can't do an update of
the catalog on every edit of an existing Journal
instance.

Any help is much appreciated.

Cheers,
Darran.

Hello,

I intend to get from fatbrain the e-matter edition of the Learning Python

The problem is that they mention that e-matter works only on windows
platforms, and I want to know if it is possible to print the book so that
I can use it while working my computer, which does not run windows.

Thanks in advance.

What would constitute a poorly engineered ZClass?  I've seen this
problem with a ZClass that is descended from just CatalogAware,
has a few properties, and for which I've rewritten the Add and Edit
methods to call reindex_object.  I'm not sure how I could engineer
this simple class better, but I don't really understand why I have
to rewrite the Add and Edit methods to call reindex_object,
so it could well be that there are improvements that could be made.

In my case, I did not even do an update catalog.  After adding
a few additional objects, the error message went away on its
own.  (I didn't do a catalog update, because if I do that the
meta data for the id field gets completely screwed up, so I stay
well away from catalog update).

I am running under SiteAccess, and I have a sneaking suspicion my
problems orignate there.  I'll be moving the database to a
dedicated server soon and will remove SiteAccess.  If I see the
error again at that point I'll let you know.

Imagine I have a python extension, with zope id pyFetch

I want to call this in a manner similar to:

  <!--#let call_method="'pyFetch'"-->
    <!--#in sql-method-returns-href-->
      <!--#var "_[call_method]( href )"-->
    <!--#/in-->
  <!--#/let-->

But I get an error:

  Error Type: TypeError

So it seems to evaluate and call the extension without adding the
parameters.  I guess I need something like lambda in python.

Can anyone help me please?

Subject: [Zope] Newbie question: using backing files.
Message-ID: <013c01bf95b2$9320f070$afe9612f@entrust.com>

I have a situation where there are some HTML files which I do not control
that I would like to open up to access through my Zope server.  I don't want
to import these HTML files as Zope objects because these files will
frequently be edited and updated in place and I want any changes made to
these HTML sources to be immediately reflected in Zope as they occur.  I
also don't want to just use a URL to access them because a) the end-users
shouldn't be aware that they're exiting Zope scope for these items and b) no
URL could possibly point to these files since they're actually stored in a
revision control system through a "view" (in essence, a virtual local
directory tree).

So what this basically boils down to is this: I'd like to take a URL like
this...

    http://my.intranet.site/Documentation/ComponentSpecs/MyComponent.html

...and have the logic behind it conform roughly to the following pseudocode:

    1. Switch to "/viewdir/source/component/MyComponent/doc".
    2. Open the file "ComponentSpec.html".
    3. Serve up the contents of that file to the user.

The user should see no visible signs that the data comes from outside of the
Zope environment.

I've already investigated using an external method to accomplish some of
this.  For example I served up an outside file in almost exactly the way I
wanted to accomplish this using code like the following:

    def testMethod():
        s = ""
        f = open("/viewdir/[...]/ComponentSpec.html", "r")
        for l in f.readlines():
            s = s + l[:-1]
        return s

Indeed this does EXACTLY what I want.  (In any production version of
this--this was only a quick'n'dirty hack--I'd be doing some significant
caching and version checking.  But the example gets the drift across.)  The
only problem is that I can't figure out how to translate a URL like the one
I provided above into a method call like testMethod("MyComponent").  (The
documentation on these things is a bit... spare.)

So does anybody out there have any suggestions?  I'm not afraid to get my
hands dirty with Python (it being my scripting language of choice for the
past 4+ years) and I'm not afraid to learn Stupid DTML Tricks.  I just don't
know enough Zope yet to even be dangerous.

Subject: Re: [Zope] Printing from Zope.....Report writer building


I got some replies about PDF document creation tools, both, products for Zope
or, Python made software.

All of those products actually create the PDF document and later on it has to
be "viewed" on the client PC with the Acrobat reader (or similar tool) and
printed from there. This is NOT operational since, the server is the one that
has to send the print request to the Linux spooler after the user pressed a
"print" button on his/her browser. The "to be printed" document HAS to be
mandatory printed (by law requirements) after user has filled in data,
checked for errors and hit "print" on the web form (not the browser's print
button).

Seems like a python code has to be written and kind of "intercepts" the
rendered web page with entered data (or just the plain data itself, with no
html tags)  and then sends it to the operating system print spooler.

It is coming to my mind to kind of build a "report writer" system for Zope
applications, after all this...Any comments? helping volunteers?

Thanks for all replies and help so far.

I haven't bought the eMatter edition of Learning Python =), but I did by the
Eff-bot's guide.  I was able to print it fine, although personally I prefer
nicely bound books to large amounts of single-sided A4/letter pages with too
much whitespace around the borders.

Also, know that some folks have had problems with eMatter's distribution
schemes, especially those with non-US installations of Windows, from what I
gather.  Luckily, I hear that fatbrain's technical support helps folks get
past these issues.

On the positive side, I do like the ability to search PDF files.

the 'address' mentioned there is the port (one of the ports) zope is
listening on. this means either you already have some process (zope?)
listening there or your os thinks that there is some process on this
port. 

in the former case look if there's one of your zope processes still
there (e.g. 'ps auxw | grep python' to list your python processes (on
linux)) or if there's some other process using it ('socklist' will
tell you if its in use); in the latter wait a little, the os will
usually grok this eventually.

We have very erratic crashes, the only commonality we can find is
volume.  When requests are low the system is awesome, but once load
starts increasing we see frequent restarts, once an hour at least.  This
could be due to people experience slower response times and breaking the
connection to attempt a reload.  From what someother people have been
saying a 'broken pipe' error in zope_msg.log may cause all the threads
to die off.  The problem here is I generated 30-40 'broken pipe' errors
and could not crash Zope.

When you run ab against it are you hitting a wide variety of objects or
the same page over and over.  I've had Zope perform great accessing the
same page repeatedly but show some strain once you vary it's diet a bit
especially when cached SQL results are involved.

What server method are you using on the sandboxes.  We use a combination
of ZServer and FastCGI connections for our traffic, with all /manage
going through FastCGI and the actual public traffic using a mix of
FastCGI & ZServer.

I can't get this to work.  When I try it all the messages come on the
screen like they should, each service that is up etc, but the darn thing
will not answer requests.  As soon as I run the exact same command w/o
strace it works.  I've also tried to attach strace directly to the
already running processes, and no luck.

As soon as I'm able to collect more info I'll forward it to you.  Is
there anywhere else I should be posting this information?

Please send any new info to all of us. I could not get strace to work
either but what is puzzling, I will get the problem even on a no load
site.

Hi,

As I didn't receive any answer from my previous message, I guess it wasn't very
clear.

How can I get a list of property.ids, property.types of a ZClass propertysheet
from outside the product containing my ZClass.

I tried a lot of things but i hit a wall.

Thanks

This should be easy, if you can get Zope read access to the files...

Use Jonothan Farr's Local File System Product.

I don't know what you mean by "python extension" -- is this an ExternalMethod? 
A PythonMethod (it doesn't look like one)?  A method of a class defined in a
Python product (I don't see an instance anywhere)?  I'll assume an
ExternalMethod, because it looks most like your stuff.

Assuming you have a folder, which contains/acquires an ExternalMethod,
'pyFetch', defined as taking two parameters, as above (I'm assuming from your
description that you have the EM with a different ID than its underlying
function -- that works, but for clarity I would generally avoid that).  This
folder contains/acquires some method, 'list_hrefs', which returns a list of
objects which have an attribute, href.

In a DTML method contained/acquired by that folder::

  # I'm using a PythonMethod which returns a list of dicts,
  #  so I am using the 'mapping' argument to get its key/values to
  #  look like attributes.

  <ul>
  <dtml-in list_hrefs mapping> 
    <li><dtml-var "this().pyFetch( href )"></li>
  </dtml-in>
  </ul>

That works for me -- I get an unordered list of the results of calling pyFetch()
on each href "attribute".

Message-ID: <01b401bf95da$0c434e90$29a8efd0@atinucleus.com>

I use an external python function to return the SQL result set.

here it is: ( I reference it as an external method called getRes in Zope)
---------------------------------------
def doPySQL(self, zQry) :
    tvar1 = 'res=self.'+zQry
    exec tvar1
    return res._schema.items()
----------------------------------------

This function returns a set of key/value pairs that are the column_name/column number

Here is the dtml document I used for testing: (UserSettings returns info for a user)

-------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=getRes('Your_Query_Name_Here()'))">
<dtml-var "_.len(t1)"> Columns<br>
<dtml-var "_.str(t1)" html_quote><br><br>
<dtml-in t1>
<dtml-var "_.str(_['sequence-key'])"> = <dtml-var "_.str(_['sequence-item'])"><br>
</dtml-in>
<br><br>
</dtml-with>
</body></html>
______________________________

This code will give you a listing of column names and values
sorted by column name for every record returned by the SQL Query:

--------------------------

<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=Your_Query_Name_Here(),t2=getRes('Your_Query_Name_Here()'))">
<hr>
<dtml-in t1>
  <dtml-in t2 sort=sequence-item>
    <dtml-var "_['sequence-key']"> = <dtml-var "_.getitem(_['sequence-key'])" html_quote><br>

Look at how Zope's management interface does it
($ZOPE_HOME/lib/python/OFS/properties.dtml).

to Garden Gnomes, is there some way that I could index every site listed in

You allready have a service that is running on a port Zope wants.

Zope wants 8080 (for web) 8021 (for FTP) and 8099 (for the monitor).

It's just a suspicion, and as I noted in my previous mail I cant tell
you constitutes a poorly engineered ZClass because I can't reproduce the
bug.  By 'poorly engineered' I mean both the possibility that the bug is
manifest of the user createing the ZClass, _or_ that the ZClass
implementation is broken.  I did not mean to point fingers.

Can you reproduce it deterministicly?

Because when you change an object, you must inform the catalog that the
object has change so it can update its indexes.

This is because one of your new objects filled in the missing hole, it
may have made the problem go away, but it didn't fix it.

This has never happened to me, can you reproduce this deterministicly

What I need to fix this is a way to reproduce it.  If you can do this,
then I need your help.  I would like to see your product, but first I
have to make sure that I *can* debug this using your product.  Your
produce needs to be self contained (not dependent on subclassing python
code I don't have) and must not use any relational database stuff as I
cannot reproduce your database environment.  In other words, if you can
drop your product into a clean Zope out of the box and reproduce this
problem, then you _are_ then man.

i had the ned for this too at the start of my current project.  I
actually have the fortune of having a smart printer.  If I shoot a pdf
via lpr, it just prints it.  It's an HP 4050.  

lpr -P HP4050_raw myfile.pdf works fine.  So I was just writing an
external method to slap that document to my printer.  But I stopped
thinking  about this because we decided online delivery of all documents
was okay and other things took priority.  

If you wanted to print more than just plain text, I guess the mime type
would have to have a "printer" application sort of, or filter just like
they have "viewers".

Has 'weighted' banners.
If you have 2 banners, each with the nromal weight of 1, each will
appear roughly 50% . If you assign a wieght of 2 to one of them, it will
appear roughly 67% of the time.

Our users were having problems accessing our site today. On examining the login

and everything was back to normal again.
Any ideas why these variable values were the same across multiple browser

Yes.  It lives in the zope extensions directory though - blame lack of sleep.

Problem: In real life, I don't know that I'm calling pyFetch, it could be 
pyDontFetch or pyGoToSleep etc (the "#let call_method" is in another DTML 
method and there are a few alternatives).  All I know is that it shares 
the same signature.  Works fine if you call it directly.

Is there a better method than the equivalent of

  <!--#if "call_method=='pyFetch'"-->
    <!--#var pyFetch( href )-->
  <!--#elif "call_method=='pyDontFetch'"-->
    <!--#var pyDontFetch( href )-->
  ...


Thanks

index_html is a 'DTML Document' and other documents are actually 'DTML

Message-ID: <38DC4561.AB3F9A72@imeme.net>

Zopistas,

how do I pull this off?

<dtml-in "objectValues(['Folder'])">
  <dtml-with sequence-item only>
   <dtml-unless noshow>
    do something
   </dtml-unless>
  </dtml-with>
</dtml-in>

I've tried messing around with the _ variable, with little luck.

This is part of a menu, and the thing is, even if I don't want to show
the folder in the menu, I don't want the menu to disappear when I'm in
the folder.

thanks,

Ethan Fremen

Hi everyone,

I'm hoping that someone on the list has some experience with NetWare's NDS.
The school district where I work is a NetWare shop with the exception of
the Web server which is running Linux. A couple of my students and I do the
Web stuff on the side.

Starting in the fall, I'd like to begin using the PTK and authenticating
users against our NDS directory. I'm wondering if anyone can tell me whether
Novell's recent release of their eDirectory product for Linux will affect
how we approach this. Are the existing LDAP Zope products sufficient?

Looking for some NDS Zen,
Tim

Some good news at last ...

When I set DEBUG in asyncore.py to 1 so I could view the lists going into
select, ZServer stabilised and hasn't crashed since. Smells like a race
condition and somehow the extra time it takes to print the list contents
stabilises things.

Still I cannot understand how the child process causes the supevising
(zdaemon) process to die too.

If your printer is setup is fine you can write the zope output to a file and
print it  using an external method 
If you can name your printale docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
pos = find(self.__name__, ".prt")
if pos >= 0:
redt = PrintJob(r)
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better
bet

This might be a seperate problem than The Mysterious Segment Violation. 
Can race conditions cause SEG faults? , I guess they can like any other
piece of code.  but I would expect a race condition to just spin the
process.  Can someone who I've spoken with about their SIGSEV problem
reproduce Pavlos' cure?

This makes me think it's a different problem also.  I get the feeling
you should be able to reproduce this problem on a fresh checkout on your
platform since it's so low level.  Can you check that?

The reason depends on how it didn't work.  Did it give you an error and

Interbase has gone open source, and the 6.0 beta version ( Windows,

www.interbase.com.

Looking at the contributed downloads, they have a Perl DBD driver, an
AOLServer database driver for Linux, and a port of the ArsDigita
Community System.

Pity there is no Zope support except from ODBC in Win32 - and that is
extremely unstable in my experience.

Hello Darran,


I created a new CatalogAware ZClass in Zope 2.1.6 with a custom Catalog 
name based on the information in the Howto.

It works fine so far. I didn't have any similar error when I updated the 
ZClass properties a couple of times.

If you can trap this elusive ZODB error please let me know. I'll update the 
howto if it's related.


Cheers.

Hello,
I have created a Zclass to publish FDF data for Adobe forms that can be used to
fill forms from zope (i.e create forms over the web). How can i get it added to
the contributed list ?. Is there a reveiw process to undergo ?

Hi, I'm hoping to get some feedback to a question I've had about whether
making ZClasses Catalog Aware is a good idea or not. Below is a my question
I asked and a few ideas from a response I received, can anyone
validate/invalidate any of these statements?

kh

Question:
------------------
Is it good practice to simply make ZClasses Catalog Aware by default, or is
this something that should only be done when necessary?

Response
----------------

 - Object cutting and pasting does not work properly for CatalogAware
 ZClasses. Is this a problem for you? Note you can still copy, paste and
 then delete the original object.

 - CatalogAware ZClasses look slightly more "fragile". I've seen posting
 about (fairly elusive) errors in Catalogs with such ZClasses. Note I never
 experienced them firsthand.

 - You could first create a base ZClass, then subclass it when creating your
 actual ZClasses. This base ZClass could include common stuff such as
 CatalogAwareness. Then if you change your mind you just need to modify the
 base ZClass. There is a way to change the base classes for a ZClass, though
 it's a hack.

Get a user name at the Zope site. Publish your product there. Someone at DC 
will approve it, and it will be on the official list.

Pretty easy. :)

How do you do that? That is my problem. Sometimes I forget a base class 
other times I have too many. Can someone write a How-to?

Subject: [Zope] Some basic questions concerning ZClasses
Message-ID: <00032518334200.08192@promotor>

I've just started to work with ZClasses. They are really cool. But I am running
into some problems:

I added a folder to my ZClass. Let's say the folder contains images. Using the
images from the folder in my ZClass methods works fine. But like all other
ZClass "internals" (methods etc.) the folder (correctly speaking: its
instance; or is there no seperate instance of the folder???) is invisible to the
management interface.

Is it possible to make a folder visible in the management interface so that
a user can enter additional images? Same with dtml methods/documents ...


Is it true that the methods of a ZClass don't open a new property namespace for
each instance? If I change the property of a method in one instance it seems to
be globally changed.

How can this be solved?


Thanks in advance

Joachim.

Message-ID: <Pine.SUN.3.96.1000325132704.16062A-100000@grendel.csc.smith.edu>

Hi all--- 

I'm trying to modify my copy of the SimpleURL product, and I need some
help. SimpleURL defines a property Sections within URLDirectory, where
each line is a section within a URL list. I've added another property to
my URLDirectory--- SectionDescriptions. I want to generate a list like
this:

SectionName1 (link)
  SectionDescription1
SectionName2 (link)
  SectionDescription2

I have the following code in the index_html of a URLDirectory instance:

<dtml-in Sections>
	<dtml-let  section=sequence-item>
          <A HREF="section_list?ts=<dtml-var 
"_['sequence-index']">"><dtml-var
section></A> <br>
	</dtml-let>
</dtml-in>


Now I know there has to be a way to modify that so that I can display the 
sequence-indexth element of the SectionDescriptions sequence. What am I
missing here?


And a design question: my URLDirectory is already fairly large; I may want
to create folders within it for each section. How would I adjust the
method above so that it looks to subfolder properties to display the same
information?

While I still have the training wheels on, I've been trying to be careful 
to understand the difference between DTML Methods and DTML Documents. I 
thought I was doing OK until I noticed this about the management interface 
(when looking at a folder):

There is a tab for Properties but none for Methods
The tab for Contents contains Methods as well as Objects

So either I don't really understand DTML Methods vs Documents, or the 
management interface should, to be consistent, also have a Methods tab 
instead of lumping methods under Contents. I'm not complaining, just trying 
to figure out the tricks so I can take the training wheels off.

Hi,

after I settled my problems with the Zope authentification system and

How can I allow a certain role to add local roles to an object? Which

solved the problem with a Manager proxy role, but I like to live without proxy

I have kind of a stupid question about sockets.  When starting zope (using

Note that what you're describing isn't really part of ZEO, it's really
more in the realm of what is already in Zope.  Thus, if you're eager to
add such a feature, you already have what you need.  Start tinkering
with the transaction machinery and see how you can extend it.

You asked one of the most tricky questions for beginners. If you look in 
the mailing list archives you will find the answer, but here my attempt:

I think of DTML Methods as functions that work on the folder they are in. 
Think about it this way: A folder is a class, then all DTML Methods are 
methods of the class Folder. They contain no properties other than id and 
title.
DTML Documents are on the other hand classes as well. So a DTML Document in 
Folder is like a subclass of the class Folder. Since DTML Document is a 
class, it can contain properties, while DTML Method does not.

Also, if you say: <dtml-var title> the DTML Method will return the title of 
the folder, whereby DTML Document will return its own title. That makes 
perfectly sense knowing the above definition.

How do I use them? Whenever DTML is called directly from the browser (like 
a link, or typed in  URL) I use DTML Documents. Whenever a document or 
other object calls DTML from inside I use DTML Methods.

I hope I did not confuse you. Don't take it as a major drawback to not 
completely understand the differences. It took me well over a month.

Regards,
Stephan

you can write the zope output to a file and
print it  using an external method 
not the cleanest way but works :
If you can name your printable docs with .prt
modify the  DTMLDocument.py  __call__ method
r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw)
----snip snip --------
pos = find(self.__name__, ".prt")
if pos >= 0:
 PrintJob(r)
--snip snip----------
Where PrintJOb is a python method that will write to a file and lpr it. If you
want the html  printed after rendering then using the pdf generator is a better.
Another idea that I have tried :
inherit from DTMLDocument and create a new object type that will send itself to
the printer at the end of processing
 embed latex with dtml  and send the results to the printer using pdflatex.
There are some cool tex macros called context written by hans hagen that 
  can be used to create rich documents

How did you save the version? Did you click on the first button you see when
you bring up the Versin object in the management interface, or did you
actively go to the Save/Discard tab, where you can enter a message and then
save or discard the change?

To make a Folder show up in the ZClass instance, you should create it from
the ZClass_add method. For example, if your ZClass is called Foo, in the
method Foo_add, you could put a line:

<dtml-call "manage_addFolder('MyFolder')">

Then, every instance will have a folder called MyFolder in it.

Same thing applies for DTML methods/documents. Check out KM|Net News if you
want to see one way to provide default documents that the user can change.
KMNN also provides a way for the user to revert to the default.

Your properties should be stored on ZClass propertysheets. Then the
properties can vary from instance to instance.

Message-ID: <0003251501490F.21205@scorpio.redspice.com>

ok  so
I am trying to export a folder using import/export
I give an export id and click on export and I get an exception
however if i give an import file name and click on  export  I get a
filename.zexp  in the var dir. Isn't this rather confusing.  Do import and
export have their own
zopish meanings ?
I am seeing really weird stuff in 2.1.4  cant wait to upgrade to 2.1.6

Now that a beta version of Pike has been released (see

given any thought to a Pike compatible interface to Zope?  It's a cool
way to interact with a content-management system.

I hope you have got your answer ,  any way my 2 cents
ssi pales in comparision to
dtml. dtml makes template programming a breeze.  You will have to learn the
syntax and ssi statements have their equivalents in dtml and more. But zope is
best for dynamic stuff.   For static pages  I would stick with the http server.
For your problem I see coding some dtml to replace the ssi and refer to the
external cgi just as usual for creating the image dynamically.

I was just looking at that earlier today. I was thinking that it might be
fun to make some Pike-compatible stuff. Also, it might be interesting if we
can set up a preferences system on top of LoginManager that is compatible
with the UserLand spec.

Mmmm... interoperability.

I looked briefly at the XML-RPC spec this morning. It certainly seems
plausible to create Pike compatible interfaces for specific products. Zope
and Frontier work pretty differently, but from a content-writer's
perspective there does not need to be a difference.

The people who maintain the _other_ Pike (http://pike.idonex.com/) will
be happy about this -- not.

Why can't people do a little name research before they hijack somebody
else's name for their project? This new Pike will only hurt the original
Pike's reputation, possibly even forcing the latter into changing its
name.

Pike is the C-like, interpreted OSS scripting language that powers
Roxen, a web/app server that competes directly with Zope, as well as
this Manila/Frontier thing.

I'm sorry, the corrected text above is what works. What never works is
<dtml-with sequence-item only>.  The error I get with <dtml-with
sequence-item only> or <dtml-with _[sequence-item] only> are:

Do you see what I was trying to do?  I wanted to see if just the
sequence-item had the boolean attribute "noshow"

Ethan,

Try something like (tested, but not in this situation, i.e. I use it a lot
and it works YMMV):

<dtml-with "PARENTS[-1].net" only>
  <dtml-in "objectValues(['Folder'])">
    <dtml-in aq_explicit only>
      <dtml-unless noshow>
        do something
      </dtml-unless>
    </dtml-in>
  </dtml-in>
</dtml-with>

| Note that what you're describing isn't really part of ZEO, it's really
| more in the realm of what is already in Zope.  Thus, if you're eager to
| add such a feature, you already have what you need.  Start tinkering
| with the transaction machinery and see how you can extend it.

Except at the ZEO level, the conflicts must have been resolved.
I only want to replicate the state of play at the ZSS end.

Otherwise I could alter ZEO to take a list of ZSSs and do a 'broadcast' and
have them all do the same work (hoping like crazy that all transactions
arrived at all servers in the same order). Then I would have n copies of the 
primary ZSS. Failover from this point is almost trivial. 

The other option is to get the ZSS to forward transactions in the order
IT gets them and send them to a list of servers it knows about. This is
slightly cleaner, since all of the Zope machines don't need to know
about all of the ZSSs.

The other major problem is, that if I do this work, I will be unable to 
contribute it back to the project for some time (if ever). I don't really
have the facilities at home to be able to do ZEO type work, my current
employers (where I have more available resources) like OSS, but, tend to 
treat it as a code repository, rather than a symbiotic relationship.

netstat -a should tell you what ports are being listened to.  try 
./start -m '9898'
and if it works, well, then you've probably got something listening to
the monitor port.

Note that while http can be virtualized (listen on selective IP's),
monitor and ftp cannot, so you have to pick your ports accordingly.

Try this (untested), assuming the name of the method you want to call is stored
somehow in the variable 'methodName'::

  <dtml-let methodToCall="_[ methodName ]">
    <dtml-in list_hrefs mapping>
      <dtml-var "methodToCall( this(), href )">
    </dtml-in>

Brad Clements has done a bunch of work on melding Python with NetWare -- he was
to present a paper on it at the last Python conference, but couldn't get there
due to weather.  His paper was part of the procedings, anyway, and may be online
somewhere under www.python.org.  His e-mail address is bkc@murkworks.com.

I think I even remember reading that he had Zope up and running as an NLM.

Subject: [Zope] Returning sequences of values with External Methods
Message-ID: <38DC6718.5080501@messagemedia.com>

Currently, I am making a lot of external methods, and I would like to 
use one like this:

<dtml-in methodname>
  <dtml-var foo> <dtml-var bar>
</dtml-in>

So basicly, I want to return a list of named values (a dist of 
dictionaries)? Are there any pittfalls you guys can see in doing this? 
suggestions?

Should I make it a Product?

Subject: [Zope] Project proposal: The Gestalt System (using Zope)
Message-ID: <38DDD362.22728102@bigpond.com>

The Gestalt System project aims to develop a free, Open Source,
object-oriented software framework which makes use of other free, Open
Source software tools for the purposes of managing, analysing, and
reporting on quantitative data in a manner which is suited to modern,
networked computing environments in which processor, memory, and storage
resources are abundant but time is scarce and requirements are forever
changing. 

The Gestalt System may be of particular interest to Zope users because
we propose to use Zope to provide some important aspects of the
project's
infrastructure.

Full details of the project proposal can be found in the Gestalt System
Manifesto which is available at http://gestalt-system.sourceforge.net

I was very confused about this  - the only Pike *I* knew of, is the core language of the Roxen webserver (www.roxen.com), which has been going for some time. As the Roxen team are about to shift version 2 of their server it seems like some lawyers are going to get some bunce here :(

Subject: [Zope] Accessing ZSQL connection from external method
Message-ID: <v04220801b503b1dd8153@[134.76.23.194]>

Howdy!

I'm making heavy use of MySQLdb in my external methods. Now I just 
realized that ZSQL-connections are kept open permanently and it would 
save a lot of time if I wouldn't have to open a connection each time 
my external method is invoked but use the already existing 
ZSQL-connection instead.
My question: How can I access a ZSQL-connection (ZMySQLDA) from an 
external method?

--Ragnar

P.S.: I benchmarked MySQLdb and found that opening a connection took 
1.2ms on my systen whereas a very short request for authentication 
took only 1.1ms. So beeing able to use an existing connection would 
result in about 100% performance gain (at least at first glance).

Subject: [Zope] anonymous Products?
Message-ID: <38DE0A95.CF7CA9A7@imeme.net>

Zopistas,

I need to have a dtml-method that does manage_clone,
manage_changeProperties, and manage_users.

It has to let an anonymous user do this:  I have to set up accounts for
people automagically.

I cannot seem- either with a product or just a straight method- to give
it the permission it needs to be called anonymously.

If anyone could give me a hint as to how to achieve this, that would be
great.

I looked at http://yyy.zope.org/Register/register.html , but I cannot
seem to get the dtml code for the actual new-user-maker.

Answer: make sure REQUEST has confirm and roles:list properties (the
latter isn't absolutely necessary, but you'd just have to set it later
anyway.)

Subject: [Zope] Performance Testing / Expections
Message-ID: <20000326232738.A30471@bob.sesgroup.net>

Ok,

I know it has been asked a couple of times before on the list, but
there hasn't really been any absolute conclusions on the type of
performance to expect from zope and/or how to tweak it for the best
kind of performance.

Over the last two days I have been doing some testing and would like 
to hear on opinions if these results are similar to other peoples.

Firstly the machine specs are:

PIII 450Mhz
128Mb 
IDE Harddrive

Running Debian Potato

Zope is running through Apache with PCGI.

All tests were run using ab.

First I tested apache to see how fast it was as a benchmark.

1000 requests, 25 Concurrent.

/usr/sbin/ab -c 25 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

Results:

384 requests per seconds (rps). Avg wait: 54ms. Max Wait. 83ms. Throughput: 20MB/s

1000 requests, 1 at a time.

 /usr/sbin/ab -c 1 -n 1000 "http://www.eminecorp.com.au/docs/testemc.html"

425 rps AvgWait: 2ms MaxWait: 3ms Throughput: 21MB/s

The I tested the same document servered statically through zope. (From zope's root)

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/testemc"

42 rps Avg Wait: 514ms MaxWait: 743ms Throughput: 2MB/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/testemc"

45 rps AvgWait: 21ms MaxWait: 29ms Throughput 2.3MB/s

Next on line was a moderately dynamic page. Dtml only, no DB or Ext. Methods.

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/sesgroup?cu
rrentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/siteinfo/index_html?"

4.97 rps AvWait: 4.4s MaxWait: 5.6s Throughput 21kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/
ecom2/sesgroup?currentid=0&cur_page=http%3a//www.eminecorp.com.au/eminecorp/ecom2/
siteinfo/index_html?"

5.09 rps AvWait: 195ms MaxWait: 198ms Throughput 22kb/s

Then finally testing a page with the same amount of DTML complexity but
some external methods which call a database using pygresql

/usr/sbin/ab -c 25 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps  Avwait 16s  MaxWait 20s Throughput 19.51 kb/s

/usr/sbin/ab -c 1 -n 100 "http://www.eminecorp.com.au/eminecorp/ecom2/products/?s
tartitem=1&currentid=22"

1.3rps Avwait 768s MacWait 789 Throughput 19.55 kb/s

In summary serving straight of apache is very fast, and doesn't suffer if 
multiple people access the site at once.

Static Zope (which you wouldn't really do anyway) was acceptable speed and
didn't really suffer too badly if there were multiple accesses.

Dynamic Zope was fair in speed, but proably still fast enough, at least for
my site anyway. It started to suffer in a bad way with multiple accesses, 
up to 5 sec response time.

Highly dynamic Zope was very bad in rps and hopeless more multiple access.

Now I have only been in this game I a while so I don't know how critical 
the multiple access thing is going to be. I am expecting at most 1000 
visitors each day (say a 10 hour period). So 100 visitor each hour shouldn't
cuase me any problems at the moment.

I guess how I would like to know if anyone out there knows how to improve 
this performance at all. Can I throw memory and processors at it and make
it go away? Obviously there are some things in the highly dynamic bit
which I will need to speed up, however how can I make just normal
dtml execute faster? The prospect of ZEO has certainly helped in this
area but surely I must be able to sqeeze some more performance out of this
machine.

Thanks in advance.

1. Generate Expires headers for your pages, and maybe handle
If-Modified-Since headers too (see OFS.Image.File for an example of the
latter.)  This lets the browser cache results of yor pages, which won't up
your requests-per-second but will reduce the number of requests you have to
handle.

2. Cache results of dynamic pages and then serve that up instead.  This can
speed things up by a factor of 5 for pages that are only a little dynamic.


I'll follow this up in a short while with an example of generating Expires
headers in DTML.

The following dtml code will tell the browser that the page expires one hour
in the future:

<dtml-call "RESPONSE.setHeader('Expires', _.DateTime(_.DateTime().timeTime()

Wild idea: Do you ever get errors when you try to compile a big, big
program, specifically the Linux kernel?  It seems as if a large number
of seemingly perfectly functioning PCs have memory errors that only
show up under specific, not well known access patterns.  Compiling a
big program is a process that can exhibit these error prone
patterns[1][2].  Perhaps Zope under load causes the same access
patterns?

[1] This is not an urban legend.  I have seen it.
[2] Search for gcc and signal-11 or sigsegv.  There are a couple of
    web pages out there about this.

I get them constantly when recompiling Mozilla, which is a daily task almost.
And bad_slab_magic, and random segv's.

I'll be running a good memory stress test soon, to see if I can pinpoint the
offending Mem. bank.

You can embed SSI within Zope. I'm currently writing a How-To on it.
Depending on how complex your inclusion is, you may be able to get away
with using Apache rewrite rules. If you want to embed the SSIs within
your Zope pages, you can resort to using SiteAccess and a call to
Client.call. Take a look at the thread "How to serve PHP within Zope"
for a more detailed explanation of what I mean. I should have the How-To
finished soon. If you are in a rush, I can send you a draft.

Well, that is food for thought today. If anyone has some really good
analysis of this (since this is my first time using AB) that would be
great.

netstat -a shows only ssh, http, smtp, sunrpc, and syslog sockets open.  
Nothing too wierd.  Like I said, using other socket numbers (e.g. 9898)
doesn't seem to fix it.

I can offer you an NDS user folder if you're running Zope on Windows or 
NetWare itself. For Linux, I suggest using LDAP

Message-ID: <Pine.LNX.4.10.10003261217150.15096-100000@odeon.net>

	Greetings,

	I've got a form that has three fields.  One for year, one for day,
	and one for month.  The selection parts of the form are similar to
	the following:

   <select name="date_mm">
    <option value="01">January          
    <option value="02">February     
    <option value="03">March
    <option value="04">April     
    <option value="05">May     
    <option value="06">June     
    <option value="07">July     
    <option value="08">August     
    <option value="09">September     
    <option value="10">October   
    <option value="11">November     
    <option value="12">December    
   </select>


	What I'm trying to do is pull the 'date_mm' (along with the other
	two fields, 'date_yy' and 'date_dd') into the namespace area so I
	can do something like:

  <input type="hidden" name="event.date" value= \
    "<dtml-var var_yy>-<dtml-var var-mm>-<dtml-var var-dd>">

	I would expect that I can use something like:

  <dtml-call "REQUEST.set('var_mm', 'date_mm')">

	However, that doesn't work like I'd hoped.

	Any help would be greatly appreciated,

	Jeff

Subject: [Zope] dtml-tree question
Message-ID: <20000326221801.A17865@owl.rhein-zeitung.de>

Hi, 

I have a problem with dtml-tree. But I think that is just a problem I have,
cause I don't completely understand the dtml-tree thing.

I have the following dtml code snippet

<dtml-tree skip_unauthorized=1 branches_expr="objectValues('Folder')" sort="order">
    <dtml-if "'index_html' in objectIds()">
        <a href="<dtml-var tree-item-url>" target="contentframe"><dtml-var title_or_id></a>
    <dtml-else>
        <dtml-var title_or_id>
    </dtml-if>
</dtml-tree>

Well, I traverse my folder structure to build a nice dtml-tree from it. So far
the insertion of links, the if-clause of the dtml-if statement, works really,
really fine. But I also want people to be able to click on the elements that
are part of the tree, so that they don't need to click on the plus signs but
can also click on the text next to the plus sign. This is the else-clause in
the dtml-if statement. But everything I tried didn't work. 

Is is solveable? And how? Or do I have to build my own tree using a recursive
call of a dtml-in loop?

Bye, Oliver Andrich

P.S.: For all of you who have seen my questions about users, roles, and so on.
I like to tell you, that I am writing a HOWTO on this, so that people don't
have to dig into the information and bother people with questions, as I did.

Looks to me like you're close...

<dtml-call "REQUEST.set('var_mm', date_mm)">

Note that there are no quotes around date_mm. Assuming that this DTML is in
something POSTed to by your form, date_mm will be available in the
namespace, and you can use it like a normal variable.

Your question is not quiet clear, but I will make some assumptions and then 
try to answer it:

I assume you want to do that all in the same file, without sending a form. 
In this case what you want to do is not possible, because you ask the 
server to know something which does not exist yet.

A form is created in the moment the user submits it. So here is how you do it:

FILE: someForm

...
<form action="someAction">
   <select name="date_dd">
      <option value="01">01
      <option value="02">02
      ...
   </select>
   <select name="date_mm">

So you combine your date AFTER the form is transmitted. I cannot think 
about a case, where you need it differently. If you have one, you should 
revise your design, since weird syntax is mostly due to bad design.

Ben,

Hi...

This topic is probably better suited for the main Zope mailing list so I
moved my reply to it there.

Err... we'd all love to see better docs written for this process.  Maybe
you can write them once you get it done.  :-)  No, Zope does not
necessarily need to be installed from source, but I think the MySQLdb
stuff needs python include libraries.

Can you give more specific questions about your problem?

Some hints anyway:

 - the MySQL development libaries need to be installed on the machine.
 - python 1.5.2 libraries should be installed on the machine

Yeah I am currently thinking of the best way todo this. I guess I now reach
another point. Does anyone know how to make External Methods persitent, or
would I have to store cached information on the filesystem. Does ZCache work
for External Methods, are there any plans todo this? I don't mind writing
code for ZCache todo this if the current framework easily allows this.

Thanks,

Benno

 I usually  create python classes instead of plain external methods and
instantiate them  as zclasses. This way I can cache information with inthe
python class as class members. If there are hooks in the zope framework to do
somthing similar (ie make use of zcache etc) please post

Not convinced that's it tho.

Side-note:  I've patched ZServer/medusa/asynchat.py line 255 - the 'first'
method - to check if self.list actually has anything on it before
returning:

        def first (self):
                if self.list:
                        return self.list[0]
                else:
                        return None

Since I did that, I haven't been able to reproduce the crash.  I doubt
that's the problem as such - I'm still leaning toward a race condition
somewhere - but the fact that it hasn't crashed since then is curious...

Oh, and strace'ing and adding debug and so forth seems to cause the problem
to display subtly different behaviour - which makes me unhappy...

Hi there,

<dtml-var str> ofcourse I get 12345678.
How can I display only part of it ? Say the first 4 chars

In python I know this can be done with something like
str[:4], str[4:6] and str[6:].
Any help ? (Hope I didn't sound too newbish !).

Subject: [Zope] Passing data to/from Python
Message-ID: <NCBBJGNEKLKGLMECHMLGIEFOENAA.wexler@ccr.jussieu.fr>

Dear Zopistas,

I am in the process of learning about Zope, and trying to
determine whether to make the switch from pure Python CGI
scripts. If someone could answer the following questions (and I
apologize, as it will probably seem naive), it would really help.

Let's suppose I have a page where the user queries a data base,
for instance a telephone directory. The telephone directory is in
an Excel file. At present, I have a CGI script that opens an
ODBC.Windows connection, executes an SQL query, and outputs the
results (names, phone numbers) as an HTML table using "print".

What is the best way to do this in Zope? Here are the points that
I don't get:

1. It seems that the only way to establish a DB connection is
through Gadfly. There are warnings everywhere that Gadfly is
inefficient. Therefore, I want to use ODBC (ODBC.Windows), like I
did before. How?

2. I might eventually need to do complex calculations on the
retrieved data, so I would prefer using Python code in an
external method, rather than a DTML method. In order to get Zope
to accept the line "import ODBC.Windows", I had to copy the ODBC
and DateTime directories from my regular Python installation
(PYTHON/lib) to ZOPE/bin/lib. But then, when I try running the
script, I get one of the following problems:

   a. If I go through authentification, the script runs, but I
   cannot establish the connection to the database.

   b. If I type in the URL of my search page directly, without
   authentification, I get a Zope error: "initialization of
   module mxODBC failed
   (exceptions.AttributeError:mxDateTimeAPI)".

Is my ODBC.Windows installation wrong, or do I have a more
fundamental problem?

3. What if my Python function in my external method wants to
return information to my DTML method? For instance, how do I
return a Python list, and what do I do in my DTML method to
process it (e.g., output a line for every member of the list)?

4. The way I call my Python function now is through the <form
method="POST" action="search"> tag, where "search" is the
external method ID. The form has a field called "name", and my
Python function has an argument also called "name", and so it
recuperates the string that was entered in the "name" field. Can
I pass the "name" as an argument to a DTML method?

If these questions have answers, I would really appreciate them.
Otherwise, if I'm completely off-base (for instance, if I'm
thinking in Python terms and not in Zope terms), please point me
in the right direction!

Thanks in advance.

Nonono.... ZOPE uses the Gadfly db to store "zope objects".  It can also
connect to other DBs, and access them via SQL methods.  There are a number of
DB interfaces, including an ODBC interface.

afaik, you can simply return a list.  As for iterating through the list, you
would use <dtml-in myMethod> stuff goes here </dtml-in>

All fields passed in a POST are available via the REQUEST.form map.  Also, so
long as they don't match the name of other objects in the namespace, you can
access then directly.  So, your 'name' field will be accessible:

<dtml-var name>  <-- assuming you don't have any other objects called "name"
<dtml-var "REQUEST['name']">    or
<dtml-var "REQUEST.form['name']">

Gadfly is just one of  the db's you can use. The aquaduct product family gives
you many options
 look at http://www.zope.org/Products/DA/ZODBCDA for the ODBC
adapter.  This is defenitely the easier way

You can do quite a bit with dtml unless of course you prefer python  and
sometimes it is easier to do stuff in python,  dtml is not a replacement by
any means

return a list and process it using  <dtml-in > which behaves  very similar to a
database cursor 
>  Can

Absolutely with the dtml  programming you can do the same things and more 
All the form variables show up in the REQUEST object and become part of the
namespace in your script,you can use them like any other variable in the
script

There's an ODBC database adapter for Windows machines.  It does not work
under UNIX.  The Sybase DA works against MS SQL Server 6.5 and below
from UNIX.

Look under "Downloads" on Zope.org.

Also read the ZSQL User Guide.

Hmm.  I've never seen ODBC.Windows.  We've punted on supporting ODBC
under UNIX, and we're now supposed to be contracting out to some other
folks to provide it for us.  Not sure when this will happen.  You can
try to write your own ODBC DA for UNIX/Linux.  There is a HowTo on
writing a DA someplace out there that Chris Petrilli wrote.

external method named "pyfunction":

def pyfunction(self):
   return ['1','2','3']

a dtml method that uses pyfunction:

<dtml-in pyfunction>
   <dtml-var sequence-item><br>
</dtml-in>

Should output:
1
2
3

If you use an external method to handle the form input, you should be
able
to get at its attributes by looking in REQUEST ala:

def myformhandler(self, REQUEST):
    a = REQUEST['a']
    b = REQUEST['b']

where 'a' and 'b' are form field names.  This can also be done by:

def myformhandler(self):
    a = self.REQUEST['a']
    b = self.REQUEST['b']

Hey Mark,

This is your lucky day... Zope does this without even blinking... I 
would say (and without starting a flame war) that Zope's ability to 
easily connect to databases is one its best features. To the 
questions...

1) Gadfly is the example. You connect to anything that there is a 
ZSQL connection product for (Oracle, Sybase?, PostGreSQL, MySQL, 
Gadfly)

2) You get back the data and can do anything you want with it. You 
can parse it, calculate it (although you might want to look into 
doing some of it in SQL) or just spit it out. Authentication has 
nothing to do with what you do with the data.

3) It is easy in DTML, just do a <dtml-in> to go over the list.

4) Yup. You build a form and send that form to a DTML method that 
processes the form. If you are super slick you have it in the same 
DTML method.

Don't worry about thinking in Python terms. I came from Python.. 
thought Zope was going to be easy, found out it hard than studied up 
a bit and now respect it. There are a LOT of things you can do in 
Zope, most of them "like" things you do in Python, just stated a bit 
different. The DTML reference guide is your buddy. You read that and 
come back here when you are truly stuck.

Now go Zope...

:)

Ok.. my mistake.. sorry.... thanks for correcting me.  I was under the
impression ZOPE stored data in a db, using gadfly as the default, and it was
refered to as ZODB for convenience.

Thanks for clearning that up for me.

Subject: [Zope] Problems with adding ZClass instances
Message-ID: <14558.57262.760790.737744@antares.int.plain.co.nz>

I'm have problems with a ZClass I'm working on that uses Folder as
it's base class and is supposed to install a set of default methods
when it's created. The trouble is that it won't when the webDirectory
is created, but it will when I invoke the same method from a tab afterwards.

Here's the body of webDirectory_add:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-if createDefaultMethods>
   <dtml-in "default_methods.objectIds()">
   <dtml-try>
      <dtml-call "manage_delObjects(ids=[_['sequence-item']])">
      <dtml-except>
      </dtml-try>
     <dtml-call "manage_clone(
            _.getattr(default_methods, _['sequence-item']), 
            _['sequence-item'], REQUEST)">
  </dtml-in>
  </dtml-if>
</dtml-with>

I'm assuming that the code within the <dtml-with ...> is effectively
opperating in the context of the newly created object, but when the
first manage_clone() is executed, it bombs out in _getCopy,
tripping over on this line:

ob=container._p_jar.importFile(f)

...because whatever container is, it's not a folderish object. 

So what do I need to do to switch to the new webDirectory object at
creation time, so adding methods is automatic?

Thanks,
John.

 Actually the limit is 4 GIG. however ext2 FS on Linux has a 2 gig limitation 
you can use a patch that will take it to 4 GIG, its available on the ext2 home

First of all, someone needs to let you know that data should never be 
stored in an Excel file. Anyway, what you would do is use the Zope ODBC 
database adapter. The Gadfly one is the only one installed by default, 
but others are availible at zope.org

You really should be storing that in a relational database though. 
Speaking for years of database experience, Excel is never a good place 
to keep things.

This isn't really a Zope issue. It's a bug in your script or the serveor

Ask those in the ODBC.Windows mailing list; this is not a Zope issue.

You might consider though, not using so many external methods and 
whether writing packages - they are more powerful and can be more 
powerful. External Methods are usually for quick one-timers.

I beleive you can do just that - return it as a list, and use it like 
this inside DTML

<dtml-in externalmethodid>

Hang in there. Learning to do this kind of thing in ZOPE is hard - I 
know because I'm trying to do it myself.

<dtml-var "search(name=name)"> should do the job, if I understand your 
question right. (Works like in Python.)

And remember: If you want performance, use any OS other than Windoze. Two 
good free DBs are PostGres (currently in 7.0 beta 3, yeah!) and MySQL. If 
you go to the RedHat site and sign up, they will send you Oracle 8i for 
free (or do they not do that anymore). I think Sybase has a similar 
promotion program. For all these DBs you have Zope DB Adapters.

Zope is cool, the docs are a big issue (I know), but a lot of people work 
very hard to change that. If you have suggestions of how to improve them, 
mail: Zope Documentation Project <zdp@zope.org>. Thanks.

Stephan

sorting is ascendingly by default (taken that you put a sort in the
dtml-tag, like 
<dtml-in sort=id>)

turning the sort to descending is done by putting in 'reverse', like so
<dtml-in sort=id reverse>

It is always ascending unless you specify "reverse" as an attribute with no 
argument in DTML-IN

<dtml-in "objectValues()" reverse sort="id">
   ...
</dtml-in>

Message-ID: <000601bf97c5$3590d960$0200a8c0@digitalview.com.hk>

Hi

I've got a load of files (PDFs, TIFs) that needs to be accessible from
within a Zope application. I need to be able to link to them so people can
download them. What is the best way to go about it?

If I add them into Zope (ie [Add new item]>[File]>[Browse]... etc is there
an easier way of doing it? I've got hundreds of files to add and I don't
want to do it using the HTML interface.

If I have the files in directory outside of Zope how do I reference them?
Bearing in mind I only need to link to them for download, no need for the
information in the files to be accessible by Zope.

thanks

By searching of the documents using ZCatalog, in query I list words with

with "OR" there is a word that is not in the index, ZCatalog finds nothing,
for example, "web or pop or mailvvv", but the documents with "web" and
"pop" exist. On www.zope.org the same effect. Is it possible to correct
this situation?

Subject: [Zope] zope search problems w/squishdot with latin1, locale fi_FI
Message-ID: <200003270923.MAA02125@katto.kaapeli.fi>

I'm using Zope 2.1.4 on Linux with environment LC_ALL set to fi_FI and
Zope started with -L fi_FI, and ZCatalog indexing & searching seems to
work fine.  (well, there's a problem with some documents having &auml;
etc. spelled out, but if ä is used everything works OK.)

BUT, ZDConfera & Squishdot don't work right.  For some reason, at some
phase of the indexing characters like ö (&ouml;, octal 366) in words
are converted to their octal codes.  This can be seen by looking at
the raw Data.fs file.  The result is that when I have a word like

kökköviesti

in the ZDConfera or Squishdot article, it can be found by search as

366viesti

It is converted in the db storing/indexing phase to something like
k\366kk\366viesti, which is then broken into words k, 366kk, 366viesti
which are stored into the textindex.

Any ideas on how to fix this?  I've looked at Splitter.c,
TextIndex.py, ZDiscussions.py and Squishdot.py, but I can't find
anything which would convert characters to their octal codes.

Aha! I have it!

Your external methods are given a pointer to self as the first
arguement.  You can use this to access any methods in the current
folder (self is the current folder)  So just call:

self.MyZSQLMethod(arg1, arg2)

where arg1 and arg2 are would be the arguments for the ZSQL Method.

Yes I am using postgres, however I am _not_ using the postgres adapter. 
I am using External Methods and python to do all data access since the data
requires formatting after it comes out of the database which is much
more easily done in python cf. dtml.

   Then you loose all the data caching done by the ZSQL methods.

Alas! It doesn't work.  It appears to fall down on the line:
  <dtml-let methodToCall="_[ methodName ]">

Traceback:
  File C:\PROGRA~1\Zope\lib\python\DocumentTemplate\DT_Let.py,

It seems evaluating this doesn't just give the string contents of the
dictionary item, it evaluates the actual external method call.

I think I'll have to give up at this point and take the cludgy option
(unless anyone can think up another way).

Thanks for your help.

Yeah I know, which is a shame, however the postgres db adapter is only a
development version and as I said we need to manipulate the data in python
before it comes out of the db. I plan on putting in my own caching routines
here, however this will still only get me up to at most 8 request per second,
which is proably reasonable for my application.

Cheers,

Hello,
i'm testing Zope 2.1.6 with Windows NT 2000. Everything is running fine
but... it's
slow updating the internal database. Each time you press the "Change"
button the wait is 30 seconds! On the same machine with Windows98SE and
Linux there is no wait.
All the other operations are working without any problems of speed.

Is there anyone else who tried Zope with Nt2000?

Thanks,

Message-ID: <38DFE1F7.290CCF16@hal.varese.it>

Hello,
i'm a fan of statistics, i want to know how many hits my sites have
received, from which country, how long, etc. etc.
I run several programs to analyze the logs from Apache and Zope but, i
don't know how to split the log files of Zope for different sites.
In my situation i have some web based only on Apache, as virtual hosts
where i can specify which log file to use for that single entry; some
are on Zope, virtual hosts done using SiteAccess and ProxyPass. Mine
problem is that i want one single different file for every virtual host
i have on Zope.
Is there a solution?
I also have problems with kill -hup, it doesn't work with python, so to
take the daily log
i have to stop Zope, take out the log and then start it again. Ok, it's
not a big problem, but that single minute of pause it's not making me
happy!

Thanks,
    Bruno

I'm running my dev-server (2.1.4) off my
win2k-box..(P2-400Mhz - win2k professional)
Usually, updating is close to instant, but occasionally i
experience 20-30 second hangs when updating.. Never thought
of it as a problem, though , as the machine is not a dedicated server
and i run a lot of stuff of it simultaneously (browsers,
photoshop,etc..)

This I cannot understand, what's new ;-)
I've mocked it up in the attached .zexp if anyone wants to try it out themselves.

I have a site with a subfolder. This is private and so has 'view' permission only to a 'user' role
and the usual 'manager' role.

I have a file, index_html in the mockup, in this subfolder, which includes an image called 'black'
from the root of the site. The root folder has 'view' granted to the anonymous user.

I added my users with the 'user' role, user1 in the mockup - password 'user1', to the subfolder's
acl_users . However, when I went to view the subfolder and logged in as user1, the page loaded fine,
except for the 'black' image. I was asked to authenticate again but the only way I could get past
this was to use user2, password 'user2', who has manage access to the whole site. 

This is really confusing as 'black' comes from the root of the site, which is viewable by even the
anonymous user, and viewing the black image on its own in another browser session, even using the
URL from the HTML generated for the subfolder index_html, worked fine and no authentication was
requested.

Obviously giving these users manager access to the whole site was unacceptable. I managed to solve
the problem, see user3 - password 'user3' in the mockup, by creating the user in the root acl_users
folder and giving them no roles. Then, giving them 'user' as a local role in subfolder.

I've tried this with Zope 2.1.4 and 2.1.6 on Linux and NT4, Netscape 3.04, Netscape 4.7 and Explorer
5.1 all with the same result.

Anyone know what's going on?

Chris

I had the same question, and found the answer in the code of the SQLSession
product.. I haven't tried coding it myself yet, but its does exactly what
you (and myself) are trying to do...

I have used <dtml-try> but it does not work.

Anyone have another way to handle this error?

If you want to use pythonish expressions in a dtml-var tag, just quote
them.

e.g., <dtml-var expr="myStr[:4]">  will get you the first four
characters of string myStr.  The 'expr=' part is optional.

Message-ID: <002d01bf97f7$73216d30$0980b1c3@net22.net>

Hi there,

I'm trying hard to make my Oracle8i  (Oracle 8.1.5.0.1)  for Linux  on
Redhat 6.0 with Python 1.52 plus python-devel installed from rpms and Zope
2.1.6 talk to each other...


As I understand so far, I first have to

Right?

I tried the new Oracle8i  setup-file provided on www.zope.org, I also tried
both Setup-Files provided with DCOracle, but everytime the same.

By the way, I suppose that there is no problem with the Oracle
client-library setup, because I am already connecting to the Oracle8i with
PHP.
I've never had problems with Python installed from rpms? Did anybody else
have?

some additional data points on those crashes:

in my test setup (CVS checkout using ZOracleDA) i found the following
ways to avoid crashing:

- using Pavlos' cure (setting DEBUG=1 in asyncore.py)

- manually closing the oracle database connection or deleting it (which
renders the membership components of my site useless since all that info
is in oracle)

- calling the offending page directly in a python interpreter by talking
to ZPublisher and circumventing ZServer

my suspicion is some weird interaction between the database adapter and
ZServer.

How can this be fixed?  

I can probably figure out how to make sure libpq (postgresql API
library) is reentrant (it might be already).  What has to happen to
the DA to make this work?

And if this was done, could you configure the DA to open, say 5
backend processes and use them in turn?

Thanks for your input.However I'm not sure that i really understand it. I
guessed that in that method the key element is popertyMap. So I tried:
<dtml-var propertyMap> in my zclass_addForm.

When i tried to add a myzclass instance anywhere in the ZODB hierearchy i get:
({'id': 'title', 'type': 'string'},)
Not exactly what i wanted. I wanted to get the ids and types of the
propertysheets properties.

Here is the purpose. I found that the default method of adding ZClass instance
is boring. The form asks you to type the id, then you can add your instance and
after that go to the propertysheets/myproperty/manage method to fill the
propertysheets properties.

I think that most of the times it's better to fill these properties when you
create the instance. So i began to modify each time, the addForm to include
the propertysheets properties in its form. It worked fine but each time i
create new ZClass i have to modify manually the addForm. So i tried to create a
generic addForm that could work with any kind of ZClass no matter what are the
propertysheets properties.

That's why i wanted to get the ids end types of the propertysheets properties of
a ZClass from outside the ZClass.

I can do that by creating an instance, taking the needed information from that
instance to generate automatically the addForm, creating a new instance with
the addForm then deleting the instance from where i got the required
information about the propertysheets. It works fine but it's not very elegant
and may a source of potentiel problems. Here is a "addForm" code that works:

<form action="ebook_add" method="post" enctype="multipart/form-data">

<table> 

<tr>

    <td><input type=text width=25 name=id></td>

Another possible solution would be to create a new instance with temporary id

Yellow,

I don't know about all you but I'm trying to use MySQLdb  0.1.2 on NT4 +
SP6a + Zope 2.1.4
The Installation Instructions aren't to precise on using it on win32
platforms and Zope doesn't show me the MySQLdb on the product list. Is there
some special steps to install it on NT?
I've seen the instructions page on zope.org and I know about having to aplly
the patch and compiling the .py on unix systems.. but what about win32?

anyone?

To use the propertysheet before you have an instance, you need to get the
Product into the namespace stack, something like this (untested, but I do stuff
like this elsewhere)::

  <dtml-with "manage_addProduct[ 'MyZClassProduct' ]">
   <dtml-in "MyZClass.propertysheets.info.propertyMap()">
    ....
   </dtml-in>
  </dtml-with>

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Hi,

I've Zope 2.1.4 running on NT4.0, using ZServer.
I would like to set up IE5.0's "Web Folder" feature
for Zope, with Zope's authentication. I could set
up a web folder, but it doesn't do authentication,
so I can't've any PUT rights...

Any thoughts?

Thanks

You should be running Zope with -D option and no -Z option, ie not as a
deamon. Then you will be able to see the connections that come in and out.
Seems though that there are two (or more) problems.

I don't think I'm following you - what do you mean 
by "it doesn't do authentication"? After setting up 
a Web Folder pointed to a folder in your Zope 
installation, what happens if you try to drag a file 
from your desktop to the Web Folder?

Has anybody seen this before? I seriously doubt my maxusers setting is
the problem -- this usually indicates an infinate openfile loop. Anyway,
the short of it is that Zope isn't starting. I'm using FreeBSD 3.4 and
Python 1.5.2.

Oops!

Sorry, folks. Stupid IE problem. I don't know
what happened, but went to MS site, downloaded
5.01 and did a complete re-install, and it is
working fine, now.

Another thing - would it be possible
to've https for ZServer webDAV? I'm trying
to push Zope's use in my organization, and
right now, am toying with the idea below
(because FTP is ruled out by our security
guy).
  - Run Zope as a webDav server
  - IE5.0 as client
  - People who want to post content to the HTTPD
    server (which is IIS3), just drag and drop
    from their PC to the Web Folder.
Issues as of now:
  - How to get the content to NT folders rather than ZODB?
      localFS does not permit uploads... May be I'll try ZMirror.

I work for a non-profit organization and right now we are
not in a position to adopt IIS5 or NT2000. Nor do people
want to go for Apache + Linux. And I could'nt find out
any other affordable webDAV server for NT.

Zope has got lof of people excited in my workplace and
that is also one reason I want to push for Zope.

Message-ID: <00032712571600.01015@modemcable215.47-200-24.mtl.mc.videotron.net>

In the Z Class tutorial (page8) I read:

"Property Sheets also allow more indirect access to properties via the
propertysheets attribute. ... we could access the 'title' property via
propertysheets.stuff.title attribute in addition to simply the title attribute.
The sort of access is handy in the case where two different propety sheets
define properties with the same name."

Sounds great, so I tried to use to it to create a sort of "international" class:

myClass:
    propertysheets
        english
            name
            description
            .....


but if i try:
myClass:
    propertysheets
        french
            name
            .....

i get the following werror message:
Invalid property id, first_name. It is in use.

So it seems that contrary to what suggests the Z Class tutorial it is not
possible to have two properties with the same name in the same ZClass even if
they are in different propertysheets at least when using the management tabs to
add a new property.

Is it a mistake in the tutorial or is there another means to add a property
with a same name in another propertysheet without getting an error?

I was just about to implement a similar method, and it occurred to me that I
would have to give a proxy role to the method so that it could add a user.
Have you tried that?

I do something very similar in the ZGotW product's root factory::

 <dtml-in "defaults.objectIds( 'DTML Method' )">
  <dtml-let si=sequence-item>
   <dtml-with newRoot>
     <dtml-call "manage_addDTMLMethod( si, '', defaults[ si ] )"> 
   </dtml-with>
  </dtml-let>
 </dtml-in>

The key here may be the inner '<dtml-with newRoot>', which is forcing the
newly-created root folder to the top of the namespace stack, so that
'manage_addDTMLMethod()' is being invoked on it, rather than on the
sequence-item.

Hope this helps!

Subject: [Zope] date property format
Message-ID: <20000327195040.3288.qmail@hotmail.com>

Hello you all!

I have a timestamp, for instance, 2000/03/27 19:57:53.9808 GMT.

Lets say I have a document property, type date, where I want to
store this timestamp.

I found that the use of A or B is different:

A)

	<dtml-call "REQUEST.set('Prop1', ZopeTime())">
	<dtml-call "manage_changeProperties(REQUEST)">

B)
	<dtml-call "REQUEST.set('Prop1', ZopeTime())">
	<form action=manage_changeProperties>
	<input type="text:date" name="mydate" value=<dtml-var Prop1>
	<input type=submit>
	</form>


The difference arise when formating for presentation:

A)
	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 18:57

B)

	Code   :  <dtml-var Prop1 fmt="%Y/%m/%d %H:%M">
	Output :  2000/03/27 19:57

Note: the 1 hour difference.

	I guess the difference is in the "Prop1:date" that forces
zope to create the correct object with all the information needed to,
for instance, recognize the GMT change since March 26.

	I found that using another kind of presentation format will
bypass this problem, i.e, instead of fmt="c style", I use functions like 
dd(), mm(), timeminutes().

	Is there a way to make the code A tell zope to create a
correct date object(property)?

My best regards,
Júlio Silva

Subject: [Zope] Creating Python class instances via DTML
Message-ID: <38DFC3D2.92037BD3@www.ifopen.com>

Greetings,

	I have created a Python class (Lead) and added it as a product and
am able to create and edit instances via the managment interface.
However,
I have run into a wall when trying to do so via DTML. Taking the path
used
in the "Adding ZClass Instances Programmatically" HOWTO, I've tried
things
like:

	<dtml-with "manage_addproduct(['Lead'])">
	<dtml-call "manage_addLeadForm">
	</dtml-with>

where "manage_addLeadForm = HTMLFile('leadAdd', globals())" appears
within
".../Products/Lead/Lead.py" and "leadAdd.dtml" contains the form used
to populate the object fields. I continually get "NameError's" on
"manage_addLeadForm" so I'm guessing that I'm have namespace issues.
Can anyone point me in the right direction?

				Thanks, Bill

Sounds like you want to roll the results into a ZRDB Results object,
like an sql query results object.

from Shared.DC.ZRDB.Results import Results

I'd suggest that you take a look at Shared.DC.ZRDB as well as Ty
Sarna's TinyTable Product which does this in a more simplistic
manner.

One of my product has a LocalFS descendent class, where I can upload
files. Well I simply use a Zope file object for uploading, then I save
the content of the file object into a NT folder. If it helps you I can
send this code for you.

Is there a way to do this using Zope-zserver, and not Zope-pcgi?
When I started this, I was just using the Zserver....but now that I need
to include calls to cgi programs for the sake of a couple images, I am
thinking I will needs Zope-pcgi..

If this is the case, I will need to uninstall the Zope-Zserver (if I try
to have both, there is a conflict) and install Zope-pcgi.  Does this mean 
I will have to import all the files, directories, etc. back into Zope, and
then reconfigure all of the files (replace all SSI lines with
dtml lines, etc)?


Thanks,

Made no difference here either.

In desperation, I moved the server behind an apache using fastcgi. Same
problem persists...random crashes with aaiiieee 11 and 256 in the debug
log, often with core dumps.

May be time to move away from the Lintel box (stock redhat 6.1, 2.16 src
install, pII350, 256mB ram) - I don't see this on a sun box I'm also
running.

Does this happen with binary installs ? Is it just redhat 6.1 (we didn't
see this on 5.2!)? One problem is that the zmonitor usually works - the
server restarts itself and users may only notice a long delay. I see it
because I'm watching the logs anxiously.

True, I still get the restart problem. What the DEBUG=1 solved was the
mysterious exits without core dumps or debug notices under very little 
load (I cannot still grok why it would kill the monitor process too).
Under high load we still get crashes but at least now when it dies the
monitor process will usually restart Zope.

We are also running behind FastCGI but as you have experienced too, we
still get the crashes, at least every 5-10 hours sometimes more
frequently. (And we have no DB connections or any weird code.)

About to give up ...

MySQLdb is the python client (driver) for MySQL.  ZMySQLDA is the Zope
Database Adaptor which interfaces with MySQLdb to access the MySQL database.
As far as getting it to run on NT,  good luck.  

Under Debian the whole process looked like this:
  apt-get install ZMySQLDA

I let some poor Debian developer worry about how to configure the two and
make it all work.

My understanding is that the MySQLdb is a patch/better driver to the 
ZmySQLDA and you need both products installed to use and you access 
the MySQLdb through the ZmySQLDA product.

Well, I just moved my zope to a Solaris box rebuilt with gcc.  I'm now
able to CONSISTENTLY get this thing to crash.

What i do is point a couple of wgets at the box to recursively snarf
up pages.  This doesn't seem to cause any  problems (yet)

Then with my browser, I try and load up some pages.  Usually, within
four or five attempts at loading pages, BAMM zope starts eating up CPU
cycles and within two minutes zope crashes...

And this is what the debugger tells me:

Program received signal SIGSEGV, Segmentation fault.

Yes, at one point, in desparation, my method had all the rights I could
grant it :)  It turned out that you have to give the rights to the
object you're cloning, too.

Hm - what we need is someone running on Solaris who can get
crashes, who also has access to purify. We're moving from
linux to Solaris at the moment, and I'll be getting hold of
purify to try and track down this damn problem.

Jon 

I did a search on the web and found out a few complains about programs
compiled with gcc seg faulting. One posting mentioned a faulty
implementaion of the pow() call, of course I have *no clue* how or why it
causes problems in Zope.

One more thing.
Can you try disabling multithreading by giving the option -t 1 to z2.py?

Good to be able to reproduce the problem. I suppose I can call it progress
...

Subject: [Zope] multipart content type
Message-ID: <38DFFDC2.AF2335FA@adroitnet.com.au>

Hi,

I need to get zope to server multiplart content.  The problem I have is
that Zope always puts its own header with a content-type,
content-length, etc on each RESPONSE.   Is there any way to stop zope
doing this?   This is a problem because the RESPONSE specifically needs
to look something like this:

        Content-type: multipart/mixed

--Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: application-compressed/zip

      {contents of .ZIP file, character for character}

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!

      Content-type: text/html

      <html>
      <head>...</head>
      <body>...</body>
      </html>

Here-is-my-really-really-unique-boundary-text-that-doesn't-appear-anywhere-else!--

I can set the content-type that zope returns by using
RESPONSE.setHeader, but i cannot control what else is put in the header,
and the order of the header attributes.  This causes a problem with
multipart messages because the boundary string needs to directly follow
the content-type: multipart/mixed, and the first message part
content-type needs to directly follow that.

Any suggestions?

Hmm... if you just want to check that everything is there, try
(untested):

<dtml-if "_.len(REQUEST.form) > X">
  render page
<dtml-else>
  go back and fix it
</dtml-if>

where x is the number of variables in your form.

Yes you can but it is more involved than the management interface. Can you
log in into the management screen of a different folder? Then you can undo
from there.

Yes and no :-) Your product's add method creates a folder object, then 
switches to it and adds the default methods with each appropriate add
method. What I was trying to do was add a ZClass based product with
the createInObjectManager method, then use manage_clone to copy my
default objects across. 

It turns out I was doing this from the right place (inside the
dtml-with that is used to create the object), but manage_clone is
broken - it let you copy objects into a thing you've just created
inside the same method at all. I'm pretty sure this is a bug - I'd be
interested to know if anyone has actually got this working at all.

In the process of testing this out, I discovered another piece of
unexpected behaviour - you can do this:

<dtml-with "manage_addFolder( rootID, rootTitle )">
</dtml-with>

...and you can then switch to using that object straight away, but if
you do this:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
</dtml-with>

...the object you've just created doesn't appear to exist as far as
the rest of your dtml method is concerned. 

So I've got something working, using the various object add methods,
but I need to make sure I have one for each type of object in my
default set, and I have a feeling that I'll need to recurse into
folders to add those and their contents. 

Thank,
John.

Just curious, but I am using a rewrite rule from apache (same things happens if
append the folder to the URL using site access) and the controls for the calendar
keep appending the root folder of the site. For instance, jobs.domain.com
correctly displays items from the /jobs folder in zope, but the calendar controls
keep appending jobs as I navigate the calendar like after a few times I get
jobs.domain.com/jobs/jobs/jobs/jobs/jobs/myCal.

Is there anyway around this?

Arg! I don't seem to be able to add anything other than DTML methods
and properties inside a Zclass creation. So it looks like I'm back to
doing it all by had. What a time saver...

Graham

please correct me if I'm mistaken - having read the How-To it seems that it
only allows you to get at the *contents* of the files. All I need is a
pointer, a reference, to the file so someone can download it.

Anyway I tried it with the following:

<dtml-var standard_html_header>
<h2><dtml-var title_or_id></h2>
<a href="<dtml-var "support['brochures']['brochure.pdf']">">Test Doc</a>
<dtml-var standard_html_footer>

When I view this in the browser I get a 'Save to file' dialog, I duly saved
the file (it was an HTML file) and on viewing the saved file I can see that
it does indeed
contain the contents of brochure.pdf(!), which is not what I want.

To re-phrase my original question - how do I construct a URL in Zope such
that it can refer to a file on the local filesystem?

thanks

The traceback is in error_tb -- try <dtml-var error_tb>

Other variables that are defined for error messages are:

  error_message (may be null)

Take a look at /standard_error_message for their usage.

Subject: [Zope] Serving external files
Message-ID: <38E068A5.11CCAA4D@rrsg.ee.uct.ac.za>

Hi,
I have some questions about serving external files:

I want to be able to serve a file that is external to Zope's Object
database. This file would probably be a binary file. So far, I have an
external method that reads the data from the file, and sets the header
of the RESPONSE object passed to it. The external method looks something
like:
    def readFile(self, REQUEST, RESPONSE):
        ...
        data = f.read()   # where f is the binary file, and has been
opened
       RESPONSE.setHeader("Content-Type", "application/data")
        return data

The zope id of the external method is "getFile".

I have a dtml method that calls this external method, using
<dtml-var "getFile(REQUEST, RESPONSE)">
The id of this dtml method is "download".
Say I have a dtm document with something like
<a href="download">SomeFile.dat</a>

This works, and the file is downloaded correctly. I want to know firstly
whether there is a better way of achieving this.
Secondly, when the user clicks on the SomeFile.dat hyperlink, and the
browser's "save as" dialog pops up, the browser uses the id of the dtml
method "download" as the filename in the dialog. Obviously I would
rather this dialog shows the name of the file that will be downloaded.
How can I change this? I can't rename the dtml method suitable for each
different filname that might be downloaded, so where else can I alter
this behaviour?

Thanks
Allen

Take three. I've solved the problem for all cases by having the ZClass 
add method redirect to a method that copies the default methods into
the new ZClass instance, then redirects back to the management screen.

Might have to write a howto for this one.

<dtml-var ***> with an image object writes out a full <img
src=***>-tag..
Your html-will look like this :
background"<img src="myimage">"

write it out as straight html :
background=myimage"

the error you're getting is probably because of the faulty
qouting in the dtml-var-tag..

Message-ID: <v04205507b5061c302dc9@[130.227.115.56]>

Hi,

I have a simple question - how do I use the fmod function in the math 
module with dtml ?

I've tried something like this(and a lot of variants):

<dtml-if expr="_.math.fmod(x,y) == 0">
	do something
</dtml-if>



What is it for:

I have some words returned from a search which I want to be displayed 
like this:

word_a	word_b	word_c
word_d	word_e	word_f
word_g	word_h	word_i

Thanks in advance.

And with good reason, you have overlapping angle brackets, your expression should read

<body background="<dtml-var "myimage">"

or

<body background="<dtml-var myimage>">

but this won't achieve what you want. What you really want is:

<body background="&dtml.url-myimage;"> 

See http://www.zope.org/Members/AlexR/EntitySyntax for more details.

Try looking at the LocalFS product available on the Zope.org site.

It makes folders on the physical drive look like part of the ZODB.

You need to recompile your kernel with an higher value for MAXUSER parameter
(x2 or x4 the current value).

MAXUSER parameter helps the kernel handle the load of the machine(max file
numbers, buffers, etc...). Python&Zope opens loads of files on the
filesystem, so the default value for MAXUSER is not enough.

Hope that helps.

Hi

The following snippet (tested) works as expected, printing the values in
three columns.

<dtml-var standard_html_header>
<dtml-call "REQUEST.set('WordList', ['word_a', 'word_b', 'word_c', 'word_d',
'word_e', 'word_f', 'word_g'])">

<dtml-in WordList>
  <dtml-unless sequence-start>
    <dtml-if "_.math.fmod(_['sequence-index'], 3) == 0">
      <br>
    </dtml-if>
  </dtml-unless>
  <dtml-var sequence-item>
</dtml-in>
<dtml-var standard_html_footer>

Yes. Use the LocalFS product, it's taken care of a lot of the things 
that you're battling with (I've done the same thing and am in the 
process of moving to LocalFS).

Again, LocalFS will do this for you (my main reason for switching!).

Subject: [Zope] Is Zope suitable?
Message-ID: <000001bf989a$f08d97a0$1e01a8c0@tingeling>

Hello!

I have some questions about Zope and I thought I ask them before
spending alot of time reading the documentation.


Can I install zope on a apache system WITHOUT being root? My ISP is
running apache on a Solaris 5.6 system.

I want to create a system that lets any user create his own User Data
Record. The user data record will contain data about the user, e.g.
Name, email address, etc. This record should only be editable by the
user (and admin) with somekind of login. This user data must then be
searchable! Listings on all or some of the data should be able to
present in different sorting orders, e.g. Lastname, country, etc.

Is Zope suited for this kind of system?
Maybe someone already has created a system like this?

   You can, but would your ISP allow you to run Long Running Process? Zope
is LRP, you know, and many ISPs are very afarid of it.
   In any case you'd nned a support from ISP to setup a way their WWW
server will use to talk to your Zope installation - pcgi-wrapper,
mod_pcgi2, ProxyPass...

We made something like this with zclasses and regular user
folders recently, using a zclass to hold the
info, and dynamically creating users with localroles in
their own zclass-instance, allowing them to edit their own
information..

Not the best way if you expect a lot of writes to your
server,i guess,  but nice enough for small sites..

Thanks -
I have downloaded LocalFS, but haven't tried anything substantial with it,
my reason being that I needed to upload these external files as well.
A user must be able to upload a file, which will be saved to the local file
system, and made available for download from the local file system. The
actual path to the file will be stored in a relational database (along with
a whole lot of other info). If I were to use the LocalFS product for this,
is it possible to add a LocalFS object dynamically (through some dtml method
that gets called when a user uploads a file)? Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.

Any comments appreciated!
thanks
Allen

Thanks, this works perfectly. I don't know why my code doesn't work 
because I have tried the same thing as you have. But I must have

Yes, but just set up a LocalFS object from the management interface 
and don't worry about it. If you're worried about files cluttering up 
the filestore, use a cron job to wipe them out.

Or (better?), is it possible
to set up a LocalFS object dynamically only when a user wants to download a
particular file (once finished the LocalFS object is deleted). I ask since,
in my case there might be many files that are uploaded, and I'm not sure
what limits there are on the number of LocalFS objects that can be
maintained.


It uses python filesystem methods, so I reckon the number of files in 
a LocalFS object (ie the directory) is os limited.

I sent an email to the list on the 21st March where I had some 
(rudimentary) dtml and python code that uploads to a LocalFS object 
(ie the directory that the LocalFS object is pointing to). Check it 
out, the subject line is [Zope] Re: [Zope-dev] RE: ZDiscussions

Message-ID: <REhvNZAilI44Ew7q@compkarori.com>

I couldn't see this covered in the Zsql user's guide.

select myfield from foo

works as expected.

As the current ODBC driver I am using has a bug which truncates varchar
fields, it was suggested I cast it to char while retrieving the field.

But

select cast(my_varchar_field as char(140)) from foo

gives an error with the following traceback...

I just found a HOWTO by jpenny: Accessing a ZSQL method from an 
external method. It helps a bit but actually I don't want to use a 
ZSQL method I just want to take advantage of a persistant connection. 
Wait, I got an idea ...

[20 min. later]
Hooray! Try this: I have an open ZMySQL Database called 
'my_connection'. Now I can query the db from my external method with:

self.my_connection._v_database_connection.query('select * from whatever')

[another 20 min. later]
I benchmarked it agains opening a connection and cursor and then 
execute() and fetchall(). Using the Zope connection took about 60% of 
the time the other method took.

I wonder if there are any disadvantages???

Synchronicity!  I've just read the same document today and found the python
code for database connections (in ./lib/python/Shared/DC/ZRDB/Connection.py,
if anyone is interested :-), and am about to try passing my own queries in.

> I wonder if there are any disadvantages???

The only one I could immediately think of was "what if the database
connection hasn't been opened".  I can see the method for
manage_open_connection() (and _v_connected/connected() for the status
of the connection), but don't feel 100% comfortable calling Zope
internals just yet.  Any caveats for just semi-blindly calling
.manage_open_connection() if .connected() returns false?

Subject: [Zope] Problems with ZCatalog-indexing
Message-ID: <Pine.GSO.3.96.1000328140758.20415A-100000@nausikaa>

Hello all,

I've got some problems with indexing in ZCatalog.

First of all it doesn't seem possible to index words containing any
non-ascii characters (most important german umlauts). On zope.org the
only info on charactersets I found was, that there are some supported
ones, but I couldn't find out which these are.

How is it possible to have a correct indexed catalog on a german site ?

The second problem is related with the first one, but not restricted to
german characters.
Words where a hyphen appears, e.g. names like 'Hans-Dietrich', aren't
indexed at all, in the example 'Hans-Dietrich'
cannot be found on the site, but 'Hans' or 'Dietrich' cannot be found,
either.

If I cannot fix these Problems, the ZCatalog is unusable in the site, as
there are a lot of important keywords using umlauts or containig hyphens.

Thanks for your help,

Tobias Kiesling

You should use a recursive mathod.

Write one method recursiveMethod:

def recursiveMethod(obj):
     result = []
     if obj.parent != None:
          result = recursiveMethod(obj)
     if obj.meta_type=='KBItem':
          result.append(obj.Title)
     return result

Then call this method like:

def GetParentNames(self):
     recursiveMethod(self)


This code is untested, but should work.

Stephan

I'm glad you found a workaround.  Just offhand, did you try to just call that
additional method, before redirecting to it?  I have seen a couple of cases
where I refactored code like that into a new method and then things got simpler.

We're phasing out hosting in favor of DASH (Dedicated Application Server

Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT for
some reason, there's an HP box available. For more details, see:

Hi,

I'm in the process of cleaning up our production Zope server and I've found a folder which has one
file in it. I don't know who created either of them and I'm wondering if they're redundant.

I'd like to find out who created the both the folder and the file and, if possible, when it was last
created. How do I go about doing this?

Cheers for any help,

Subject: [Zope] Newbie question - product embedding
Message-ID: <38E0C7B5.38276033@advis.cz>

Hello,

I am just evaluating the Zope system, and it looks good. I am trying to
build an example Intranet site, using Squishdot.
I need a poll embedded in one of the Squishboxes.

I tried both PMPPoll product and Poll product, but cannot get it to
render into the page.

I have a DTML method calling the poll object like this


... some simple HTML ...
<br>
<dtml-var name="my_sample_poll">
<br>
.. some more simple HTML ...

The simple HTML indeed appears in the box, but instead of the poll form,
which I expect to be rendered, I get the following in the page source :

<br>
<Survey instance at 8635589>
<br>

Am I missing something obvious? Should I call the object from within my
DTML method some other way? Thanks for your help.

Hi,

Yes, this gives me parents, but it doesn't work for my problem :

The external method is used for storing the information into a ZCatalog.
Now, when the Catalog is updated, I get the wrong parents, I get the
parents of the catalog and not of the object itself. :-(

Somebody another idea?

Tom.

I tend to agree with Tres here. MySQL can certainly handle BLOBS, but
here's something you might not realize: All MySQL queries are literals.
Let that sink in for a moment. What does this mean? Suppose you are
using MySQLdb (not a ZSQLDA, we'll get to that). You need to do
something like this:

c = db.cursor()
c.execute("INSERT INTO BlobCity (Pix) VALUES (%s)", pix)

Looks simple, doesn't it? Well, here's what happens behind the scenes.
First MySQLdb has to turn pix into a MySQL literal value. Fortunately, if
you have, say, a JPEG class, you can write a function (not method) which
converts it into a MySQL literal. Suppose your class has a __str__ method
which returns the raw data as a Python string (maybe it IS a string
internally). Then you can do:

def JPEG2Literal(j): return "'%s'" % MySQLdb.escape_string(str(j))

(Although this is actually the default converter, used for strings; if you
have a __str__ method, you can just pass it to MySQLdb and it should do
the right thing.)

MySQLdb.escape string does all of necssary escaping of special characters,
namely backslash, NUL, and single-quote. But to do this, it has to
allocate a temporary buffer that's twice the size of the original string
to handle the pathological cases. Then quotes have to be added. Then this
all has to be inserted back into the original query. In the case of a 5 MB
BLOB, these steps work out to be:

1) str(j): 5MB
2) escape_string(#1): intermediate 10MB, return new 5MB+ string
3) "'%s'" % #2: return new 5MB+ string, but del #2
4) querystring % (#3): return new 5MB+ string, but del #3

So you're making and destroying a lot of big strings, which takes a
considerable amount of time. And we're only using one column and one row.
(I should probably make a new C function that combines #2 and #3 for
efficiency.) Most of what MySQLdb does is string crunching. For that
matter, MySQL returns all values to the C API as strings (including
numbers).

And now the Zope ZMySQLDA case: Z DA's always build literal queries
anyway, so this makes MySQL no worse off than any other database. (Most
database APIs, like ODBC, seem to use positional placeholders in the query
and pass the rows/columns as a data structure, which makes for much less
parsing on the server side, and is much easier to construct on the client
side.)

Compare this to writing into the filesystem. Well, no comparison, really.
open, write, done. So long as you can keep things organized, you're ok.

I'm guessing I could do it with MySQL...  what does everyone think?  
Is there a Zope plugin that already does this.  
Does someone have some code laying around you could send me?

MySQLdb is not a Zope Product; it's a Python module. ZMySQLDA is the Zope
Product. It needs to be patched to work with MySQLdb, however. I have no
idea how you would do this on Windows. Only the Python code (no C code)
needs to be patched. Stay tuned...

Message-ID: <3.0.6.32.20000328181014.0092e0c0@poirot>

Ok, now I found the error. The error must be in the while loop, where we
say 'iterate until the obj = None'. However 'None' is never reached... (I
guess). 
The following code works, but I this isn't at all a good solution. 

Can someone tell me how I can safely test that the current object is the
first object in the object database. In other laguages you can test this
with 'nil'. How can I test this within Zope? Please, tell me!

def GetParentNames(self):
  result=[]
  obj=self
  while obj.title != 'Zope':
    obj=obj.aq_parent
    if obj.meta_type=='KBItem':
      result.append(obj.Title)    
  return result

Thanks in advance,

Tom.

You must your locale environment variable correctly.  See 'man locale'
on linux, for example.  Also, you can pass z2.py the -L argument to
explicitly set a locale.  This will allow you to index german
characters.

Hyphens are hard coded in the text index to split words.  This is
because the text splitter is not very flexible and is very english
centric.

To fix this, you must either 1) create your own splitter, 2) update to
the latest CVS and create your own vocabulary and provide a new
splitter.  

The CVS version of Catalog is much more language neutral, and there are
now two kids of vocabulary object, English and Globbing-English.  Soon
someone I'm in contact with will be providing a Japanese vocabulary.  If
you have the patience, you should developer a German vocabulary to
address these issue.

Sometime between when your catalog was generated and when you tried to
re index the content you updated your CVS sandbox.  When you did this,
you got the new catalog code that doesn't work with old catalogs.

This non-backwards compatability has since been fixed.  If you update
your CVS to the most recent version this error should go away.

Let me know if it doesn't.

I think this would be a useful addition to the Zope core...I find
myself doing the same thing and I've been thinking about developing
the generic add form but haven't had time to even start it.

This works for me:

<dtml-with right_poll>
  <dtml-var index_html>
</dtml-with>

Of course you'll have to modify the poll's index_html document to
remove all of the full page stuff because you only want a table cell
for rightbox items.

Hi!

First of all I've to say that I'm a realy beginner in Zope.
I recently updated from 2.1.3 to 2.1.6 and noticed following problems:


In 2.1.3
<dtml-with "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
  <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
  </dtml-in>
</dtml-with>
 works great

In 2.1.6 it produces an Error message that
title, empf_sem, diplompruefungsfach is not known by the system
(I already Posted that)

Now I found out that
<dtml-call "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)">
 <dtml-in "getSubjectInfo(fach=REQUEST['fach'])">
    <dtml-call
"_.getitem(REQUEST['fach'],1).propertysheets.Basic.manage_changeProperties(title=fachbez,
empf_sem=empf_sem,diplompruefungsfach=diplfach)">
 </dtml-in>

works fine in 2.1.6. (getSubjectInfo is a SQL Method)

Has someone a hint for me?

Helmut.

Subject: [Zope] RE: ZCatalog Indexing
Message-ID: <38E0EC1E.7DBC7011@hiretechs.com>

Tobias,

The Catalgo uses a stripper to make the indexes smaller. It doesn't
index =-+*&)(^%$#@. etc... or numbers.  Some words too like 'Bill'. From
what I've been told there is a version of the Catalog on it's way which
will allow you to put keywords or charaters in a special place that will
include them.  I couldn't wait for that, and I love Zope, so I came up
with a major kludge.  catalog_quote() and catalog_unquote().  They are
from an External Method which I wrote catalog_quote.py.  Here it is:


from string import strip, split, join, uppercase, lowercase, find
bad_characters=(('.'),
                ('+'),
                ('-'),
                (';'),
                (':'),
                ('&'),
                ('*'),
                ('%'),
                ('#'),
                ('@'),
                ('$'),
                ('0'),
                ('1'),
                ('2'),
                ('3'),
                ('4'),
                ('5'),
                ('6'),
                ('7'),
                ('8'),
                ('9'))

def catalog_quote(self, ascii):
    text = str(ascii)
    for re in bad_characters:
        if find(text, re) >= 0: text=join(split(text,re),ordinalize(re))
    return text

def ordinalize(letter):
    number = ord(letter)
    number_string = str(number)
    myletters = lowercase[-5:] + uppercase[-10:]
    converted = ''
    for character in number_string:
        converted = converted + myletters[int(character)]
    return converted  + 'g'

def catalog_unquote(self, ascii):
    text = str(ascii)
    for un in bad_characters:
        if find(text, ordinalize(un)) >= 0:
text=join(split(text,ordinalize(un)),un)
    return text


I just use it to turn anything that might contain the charaters in
bad_charaters into catalogable stuff.

Then when you search, you must catalog_quote() your search strings, and
you'll get 100% accurate results.  Hope this helps.


All my best,

Message-ID: <3.0.5.32.20000329041128.009adc20@mail.skinnyhippo.com>

I had a ZClass (InnerClass) which was defined within
another ZClass (OuterClass) as follows :

/Control_Panel/Products/MyProduct/OuterClass/InnerClass

And a great many instances were defined with both
the OuterClass and the InnerClass. However, in order
to catalog the InnerClass (it is not CatalogAware 
and I do not want it to be), I need to move it to

/Control_Panel/Products/MyProduct/InnerClass

in order for 'InnerClass' to appear in the select
list ('Find objects of type') under the 'Find items
to ZCatalog' tab of the ZCatalog.

So far, so good. I moved the class and now can 
catalog it. However, now the icon is broken on all
of the instances of the 'InnerClass' ZClass. I 
have tried adding a new icon under the 'basic'
tab of the ZClass definition, but that doesn't
help either. I know it's just a petty icon and
it doesn't affect functionality but I'd really
like to clean this up so any clues/help appreciated.

Thank you very much,

chas

Hi all,

This code results in a error:

<dtml-let MyVar="_.string.replace(Mytext,'"','&quot;')">

I know its because of the quote in '"' because that cause in
same way an error when the "dtml parser" is parsing the code.

I've tryed to use '\"' and even _.chr(34) instead of " but the former gives 
me the same error and the latter dont give a error but also
dont do the string replace I want to do.

Any help?
Thanx,
Julio

This one goes especialy to ho write zope.

I have found that the dtml-in has a problem when you specify a batch-size that is less than the double of the length of the input list.
Ex.:
a list of 6 itens:
when size is 3, dtml-in returns 3 itens, correct. (3*2 <= 6) = true
when size is 4, dtml-in returns 6 itens, error. (4*2 <= 6) = false

Is this a bug?

Adding an "orphan=0" tag inside the dtml-in should do it:

  <dtml-in foo orphan=0>
    . . . bar . . .
  </dtml-in>

A more general question for the list, though:  Shouldn't the default
orphan value be zero?  It seems to me that if someone explicitly says
"I want three items," it should be more of a special case that they'd
somehow want more . . .

Opps. It works, but my sugestion of using _.chr(34) also works.
I was looking at the wrong results when testing _.chr().

Tried that - I in-lined it on the list for brevity's sake. The problem
is definitely with manage_clone not wanting to be used on a thing
inside the transaction that creates that thing.

Message-ID: <71D21CF19DE2D011AD43006097BD8C019D5C7B@SJMR-MSG-01>

Sometimes when I reference other dtml documents I get the dtml code returned
as text,  rather that outputting HTML like it should.  For example,  the
code I have below will print out the standard header properly and then
display the raw html where the Eligibility.MemberInfo document should be.
What am I doing wrong?

<dtml-var standard_html_header>
<dtml-in SQL_ViewMember>
 <dtml-var "Eligibility.MemberInfo">
</dtml-in>
<dtml-var standard_html_footer>

Hi there,
This must be simple, but I haven't found it in the docs.
Can I get ZopeTime to give me the date, say, 20 days ago ?
Or a month ago ?
Something like (yes I know this won't work) 
<dtml-var expr="ZopeTime - 20")

One thing you need to keep in mind is that dtml-in has an orphan
attribute that determines the minimum amount of items to print out.  If
orphan is set to 3 (default) and you have a list of 6 items, and you set
size=4, the dtml-in tag will realize that 2 is too little to have on one
page and so it displays all 6.

If you don't want this, set orphan=0 in the dtml-in.

Subject: [Zope] BASE tag on File objects
Message-ID: <m38zz23a9e.fsf@wacko.pdx.net>

I've got a number of static HTML files on my site that Zope keeps
putting BASE tags into.  IMHO, it is inadvertantly appending a slash
onto the end of the HREF.  For example a file called default.htm in
the classified directory ends up with a base tag of:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm/">

I would think this should be:
  <base
href="http://www.nationalmortgagenews.com/classified/default.htm">

So I have modified: OFS.Image.File.index_html to strip the trailing
slash by adding:
        # clean up the base if neccessary
        if( RESPONSE.base[-1:] == '/' ):
            RESPONSE.base = RESPONSE.base[:-1]

What think you?

-Jon

This should work:

<dtml-in SQL_ViewMember>
  <dtml-with Eligibility>
    <dtml-var MemberInfo>
  </dtml-with>
</dtml-in>

There could be a way with zserver but I don't know it. My advice is to
use PCGI for performance and salability anyway, though. ZServer is
quicker to setup, but in a production environment, apache is still
higher performance.

Although, having CGI scripts are never good for performance. ;) PCGI
is fine though.

You can generally have both pcgi and zserver installed without a
conflict; there's just no point to it. There very well could be a way
to "wrap" CGI scripts in zserver, but it would still be better done
in a true apache environment, where it belongs. To be 100% ZOPE you
would re-implement everything in Zope/Python/DTML though. I've seen
a lot of company areas where zope stuff points to CGI stuff and visa
versa, so your situation seems to frequently be solved that way.

You only need Zope-pcgi if the cgi calls need to come off of the
same IP as the rest of your zope.  If your Zope site is, say,
www.mysite.com, then you could put your image cgi stuff into an
Apahce responding to the an IP under the name of, say, images.mysite.com.
This would be your maximum performance route: direct calls to
Zserver for the Zope stuff, and direct calls to Apache for the cgi
images.

You only need the separate IP, by the way, if both need to be listening
on port 80 (say because people from behind a firewall need to access
your site).  If you can deal with either one listening on another
port, then Zope at least can deal with that (I imagine Apache can too,
but I've never tried it.)

> If this is the case, I will need to uninstall the Zope-Zserver (if I try
> to have both, there is a conflict) and install Zope-pcgi.  Does this mean 

What have you run into that makes you think there is a conflict?
When you run Zope using pcgi, you are still running Zserver.  It's
just listening to pcgi calls instead of port 80 (or whatever) calls.
It is certainly possible to run Zserver such that it will respond
both to direct calls and to pcgi calls.  This is the way it is set
up by default, at least under Unix if you compile Zope using
w_pcgi: Zserver listens on port 8080 for http traffic, and also
communicates with Apache using pcgi.

Reinstalling to add pcgi support is like upgrading to a new version
of Zope: copy your var directory (actually just Data.fs should be
enough) to a safe place, do the install, and then copy your saved
var overtop of the new one built by the install.  You'll also need
to reinstall any Products that you downloaded and installed.

Hi,

I am looking for a translation engine (similar to Babelfish) that can 
be fully integrated with Zope. The only option I found so far is 
GPLTrans, which is based on PHP. Before I start porting it to Zope: 
is there anyone else out there already working on a similar project?

Anyone interested in helping out with such a project? Have a look at

   http://babelfish.altavista.com/
   http://gpltrans.sourceforge.net/

to see what I am talking about. Results to be released under the GPL.

Thnx,
Jonathan

Hi,
How do I import a module - I've been reading the DTML guide, and I would
like to use some of the functions described in the string module, but
how do use them - do I have to import the module (if so, how), or what
else. What I want to use is the following:
<dtml-if expr="lower(somestring)=='supplier'">

</dtml-if>
where lower is defined in the string module. I've also tried
string.lower(...) but that didn't seem to work.

thanks

I don't think you'd need any Zope products or additional code for a basic
implementation of what you want to do.

Just create the folder structure you want to have in Zope. Then you can add all
your documents with the management interface. To create the directory view, you
only need an index_html DTML Document that lists the folder structure (either
using the tree-tag or some dtml-in construction). 

For higher performance, you can use the ZCatalog to index the folder structure
and use code similar to the one on Zope.org to list the topic pages (e.g. all
the news on the Zope.org news page and all the products in the download area
are collected from the site using the ZCatalog.

I wouldn' use MySQL for that particular task because it fits the ZODB (Zope
object Database) perfectly (many reads, few writes).

You could also look into some of the products on the download page. I recall
that there might be some "out-of-the-box" directory solutions.

I'm finding myself again trying to figure out how things work in Zope, just
to find out at the end that it is MUCH simpler that I thought  -- but totally
undocumented! Or maybe I just haven't looked for it enough ...

Isn't there somewhere a list of all method calls I can use from DTML (like
manage_addXYZ)? It can't all be just trial and error or "read the code". -- Yes
it can, but I don't want to be that pessimistic ;-)

O.k., my current problem is that I have a folder with icons and images in a
ZClass that should be copied to all new instances of the class.

There seems to be a "manage_clone" call for that (just read about it in a
posting), but how does it work and where do I find any documentation on it?

As all those methods are in the namespace, isn't there at least a trick to get
a list of all names to print out? That would be a first start.

I mean, I had to figure out every single call like manage_addDTMLDocument or
manage_changeProperties by trial and error. That makes Zope so much less
efficient that it could be ...

The string module is already available, just not as you'd expect ;)

Try something like:

<dtml-if expr="_.string.lower(somestring)=='supplier'">

</dtml-if>

You could also try <dtml-var "Eligibility.MemberInfo()"> although this might to use the namespace

from the zqr: 

manage_clone(ob, id, [REQUEST])
           Clone an object, creating a new object with the given id.

have you tried :

<dtml-var "Eligibility.MemberInfo(_.None,_)">

- just might do what you want..

Don't ask me about the specifics of what  (_.None,_) does,
though.

Subject: [Zope] passing arguments from dtml methods to SQL methods
Message-ID: <38E1D121.D5689279@rrsg.ee.uct.ac.za>

Hi,
Thanks for previous help on the namespace variable '_', much
appreciated!

I have another problem though, how does one pass parameters between DTML
methods, and from dtml methods to ZSQL methods?

I have a DTML method "getSearchResults" that gets called when a form is
posted using
<FORM... action="getSearchResults">
<INPUT NAME="fname"
</FORM>
The method gets called and magically the form fields like fname
described in the above form are accessible from the dtml method, so I
can do <dtml-var fname> and there's the input from the user. (I still
don't fully understand how that bit of black magic works...)

Ok, then I have a ZSQL method with fname as an argument, and again, when
my dtml method calls the zsql method, that variable fname can be
accessed using <dtml-var fname> in the SQL query. While maybe I don't
completely understand what's happening, I can still use it. The problem
now is, my ZSQL method needs to have an argument "tablename" that it can
use so that a different table can be selected, however, this tablename
is not under the user's direct control. It gets set according to some
choices that the user makes along the way. I would hence need to
"declare" it in the dtml method "getSearchResults", initialise it, and
pass it to the ZSQL method so that the ZSQL method can use it. I tried
doing the following: (suppose the ZMYSQL method's id is "searchMySQL").
in the dtml method:
    <dtml-if expr="whatever">
       <dtml-var name="getSearchResults(fname=fname,
tablename='suppname')">
    </dtml-if>
So that didn't work, but maybe it describes what I'm trying to do - that
is, fname exists and is initialised from the user's form input, but
I want to create the variable tablename, and pass it to another method
(or just create in the namespace space so that it's accessible to other
methods).

Sorry to be so long-winded, trying my best to describe things with my
very limited knowledge of zope/python.

Many thanks
Allen

Hm, is it - if it's undefined? 

what about (taking the function from one of your previouw posts) (only
lightly tested):

def recursiveMethod(self, obj, result):
    try:
     if obj.aq_parent:
           result.append(obj.title)
           recursiveMethod(self, obj.aq_parent, result)
    except AttributeError:
        pass
    return result

This is less elegant than testing for the attribute aq_parent, but
either hasattr is not allowed for External Methods, or ac_parent is not
an attribute.

Note, however, that if an object has no title it may also throw in an
AttributeError, thus aborting your method in too early. You could try
and catch this exception separately, but perhaps it shouldn't happen
anyway.

One small addition: I threw out the test for KBItem (because my Zope has
no such items), you can put them back in at line 4. Sorry for posting

Try using a COUNT in your SQL select formula. 

e.g.

Select count(colname) from tablename where colname='myvalue';

If it returns a 0 then that value doesn't exist.
If it returns anything then that is the number of times the value exists.

How about

<dtml-in "sqlFindItem(item=itemid)">
  <dtml-if sequence-start>
     do insert
  </dtml-if sequence-start>
<dtml-else>
     do update

Is it possible for zope to separate control from data automatically?

To make the best use of Zope, it will be necessary to separate the data and
control.

with XML, DOM will assign id for each node and thus  all of them can be
refered by that id.

Is it possible for zope to perform this? Will a modify of  load_site able to
do this semi-automatically? (run load_site over an existing zope tree?)

Message-ID: <Pine.LNX.4.10.10003291331390.19425-100000@oeh.tu-graz.ac.at>

if you want to pass variables to a dtml method you have the option to
set it in the REQUEST object eg.

  <dtml-call "REQUEST.set('varname', 'somestringval')">

or put it in the namespace eg.

  <dtml-let varname="'somestringval'">

then call your method as per normal eg. <dtml-var yourmethod> which
then will find the vars you set before.

or you call your method with keyword args like

  <dtml-var "yourmethod(_.None, _, varname='somestringval')">


note the difference between 

  <dtml-var "method"> which is <dtml-var expr="method">

and 

  <dtml-var method> which is <dtml-var name="method">


see the "Document Template Markup Language Reference",
http://www.zope.org/Documentation/Guides/DTML and the zope howto's.

Salutations,

I've been staring at this one for a while, but I can't quite seem to
pull it off.

I'd like to render a document based on the contents of a variable.
For example (simplified):

<dtml-call "REQUEST.set('foo', 'index_html')">
<dtml-var foo>

should (would? could?  I'd like!) render index_html.  Double
quotes don't cut it (both print the string 'index_html') :-(

- Because PrincipiaSearchSource (which is probably what you
are using for your full text search) is a property(method?) of DTML document and
method, but not of your new product..

try making a pythonmethod or external method (pythonmethod
is simpler) inside your
Zclass containing something like :

   return string.join((self.yourAttribute1, self.yourAttribute2, self.yourAttribute3), '; ')


where yourAttributeX are the attributes of your Zclass..add
as many you like...

name it PrincipiaSearchSource if that's what you're using
for the full text search.. (might be 'raw' too...)

Hi,
Thanks again for the help with the let and with tags...

I am making slow progress, but now can't seem to display my results from
a ZSQL method. How are the results returned? If they are in some
RESPONSE object, how would I read the items out?
So far, I have an SQL query which I'm fairly sure is working, and whcih
when tested gives the results I expect, but when I use it in the
following bit of DTML, nothing is rendered at all:

<dtml-call "REQUEST.set('cmatch', 'sup_name')">
<dtml-var searchMySQL>

The <dtml-var searchMySQL> line returns nothing, even though I know that
there are results for that method.

Apologies if I'm missing something I should be picking up from searching
the archives, but at the moment our connection is bogged down with lunch
time traffic, so I can't even get to the zope site.
thanks
Allen

No biggy..

<dtml-in searchMySql start=query_start>

<dtml-var variable_name>

</dtml-in>

That should get  you started but you should read the ZSQL Guide as it 
has lots of options that you can include (size, orphan, start 
sequence, end sequence, etc)

Really is worth the read.

Bear in mind you may have two pythons running on your machine.. the 'normal'
python that appears when you type 'python' at the command line, as well as
the python that zope installs. It may be that PIL is only in the path of the
former and not the latter.

In my case, 'foo' must be a string, and is actually passed in via
a POST (I need it to maintain state in a "wizard" style form).

Subject: [Zope] ZRDB
Message-ID: <38E22874.727DD231@wildenhain.de>

Hi,

browsing thru Shared.DC.ZRDB.Results i found this construct:

-------- line 117 ------------
		if not name:
			raise ValueError, 'Empty column name, %s' % name

------------------------------

This looks a bit silly, because if name is empty, %s will be replaced
with
nothing...
Furthermore, would it not be better to provide a generic name for the
empty column? Sure, it is difficult to provide such a name who does not
collide with others in namespace, but it would be very helpful, if the
underlying database-adaptor does not provide full names under certain
circumstances, such as ODBC with CenturaSQLBase always returns
empty column names to Zope with the count() Operator. Even if used "as"
to rename.
How about something like:
		if not name:
			name='column%d' % i

or such?
Next there is always some hassle with those 'table.column' columns
returning from databases who do not support column renaming.

Would it be a way to rename them automatically to something like
table_column? Yes, I know there could be a column already beeing 
called so. But if one knows she can use table.table_column in such
circumstances.
May be as alias?

I'm coming in late on this thread, so ignore me if this 
has already been covered... :)

It sounds like what you want is something like the following:

# docname is the variable passed in via the POST whose
# value is the name of the document to render. We use
# _.getattr(this(), docname) to retrieve the needed 
# document from the current object. Note that we use
# the "let" tag instead of REQUEST.set, which is 
# increasingly considered evil :)

<dtml-let theDoc="_.getattr(this(), docname)">
  <dtml-var theDoc>
</dtml-let>

Subject: [Zope] Problem with SQL+Special chars...
Message-ID: <B507F9A6.5E85%owrede@khm.de>

I am having a problem with HTML entities.

I am using Zope to enter and output text into a MySQL Database.

When I output the text, it is rendered through my own External Method:

   <dtml-var "myMthod(myText)">

I tired to write a little subrouting which is supposed to translate special
chars in the database into HTML during output.

Unfortuneatly the texts are entered on both MacOS and Windows browsers. This
unfortunatly makes it difficult: There is no unique ASCII code in the
database -- in other words: the same special char may be represented in the
database with to character values.

First I looked if the <dtml-sqlvar ...> had anything to offer, but that does
not seem to be the case.

How can I store text in ISO-Latin into the database regardless the Text is
entered via a Mac-Browser or a Windows-Browser?

Message-ID: <38E22FB4.7C8FFF18@nipltd.com>

Can you do colour in structured text?

The reason I ask is that I've just found out how great ZWiki Webs are but I'm wondering if there's a
shorter way of changing text colour than:
<FONT COLOR="#xxxxxx"> </FONT>

I'm looking to use a Wiki so a group of people can edit a web of documents and I was hoping that
each person could use a different colour. Having to do the colour by hand defeats the simplicity of
a Wiki :(

Any ideas?

Subject: [Zope] Mac2ISO conversion?
Message-ID: <B507FECC.5E86%owrede@khm.de>

I need to enter text data into a MySQL database via HTML forms.

Text entered on a Macintosh client is not ISO-Latin as it seems. When
getting that text out of the database, the special characters are broken in
the HTML page but not in the textarea.

Text entered via a Windows browser are not broken in the Mac browsers HTML
page - but in the textarea.

So I guess I should care for getting ISO-Latin text from the Mac clients
into the database!

From other areas I know this requires a mac-to-iso translation (in both
directions (because the text must be editable on Macs).


But how can I do this in Zope?

I know how to figure out, if it's a Mac-Client -- do I have to create an
External method fr this?

Hi,

I'm doing a back link to go on a page (yes, I know browsers have back buttons, but some people don't
like to use them ;-) which is easy enough:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>

except that if there is no referer, you get a key error. So I thought I'd try the following:

<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>">Back</A>

But I still get a key error. I thought the 'missing' attribute was supposed to catch that?

   Not quite. You are tripping a key error here so that won't work. Try:

<dtml-if "REQUEST.has_key('HTTP_REFERER')">
   <dtml-var "REQUEST['HTTP_REFERER']">
</dtml-if>

It still exists, in a very domant stage.  The next Zope release will
probably break it right out.  There's not much you can do with ZTables

Subject: [Zope] building/exporting site and server question
Message-ID: <4.2.2.20000329111442.00a63b10@mail.bowmansystems.com>

I am relatively new to Zope, and I am working on a personal project at home 
on my Win98 box. I am just now getting the "zen" of Zope as everyone refers 
to it, and am building a true functional application.

So now that I am getting comfortable with Zope, here is my question. I am 
wondering if I can build my site/application on my Win98 box at home, 
export it out and then import it into another Zope installation running on 
another operating system (either BSDI or Linux). I am thinking I will have 
to buy my own server so that I can let Zope run as the server itself -- our 
servers up here all run Apache and I doubt our systems administrator up 
here would want to take the time and effort required to get that running 
properly (plus those are production servers, not really for employee 
projects!).

Is it possible and/or recommended to build a site/application on one 
installation and import it into another? Or should I just go ahead and by a 
box, put Linux on it, and proceed to build it on that platform? My concern 
is spending a lot of time building out the site on my home box and then 
finding a show-stopping hitch in the migration to another 
platform/installation.

Anyone who has had any experience with migrating Zope applications to other 
platforms/installation please reply so that I can make an informed decision 
as to how to proceed.

And also is there any reason to use Apache instead of letting Zope run as 
the server itself -- this will be on my own server so I doubt there will be 
much else on the box then my personal project and my home site (two virtual 
domains).

Thanks in advance.

This counts only for something like <dtml-var ought_to_be_missing
missing>
In your case you are inside Python when calling with " ".
So "missing" cannot catch this exception.
(Actually this simple <dtml-var .. > does much magic :)
So in your case you should do:

<dtml-if "REQUEST.environ.has_key('HTTP_REFERER')">
	<A href="<dtml-var "REQUEST.environ['HTTP_REFERER']">">Back</A>
</dtml-if>

This has the advantage of no blind link if there is no HTTP_REFERER set.

The reasons I came across were if you wanted to use SSL or have a site that
is half Zope, half Apache. Otherwise for simplicity sake ZServer by itself
is a great option. It is certainly the fastest and easiest to set up.

I decided to swith the roles, as I have ZServer running on Port 80 and
Apache on 8080 to sever up statistics, documentation docs and other very
static and non-production things that would be difficult to get into Zope.

As for the W98 migration, I would say develop it on the box you are going to
use it on. In the long run all the experience you get on the development
will not transfer to another OS. Linux is a great way go.

Btw. this works:

<dtml-with REQUEST>
  <dtml-with environ>
    <dtml-var HTTP_REFERER missing>
  </dtml-with>
</dtml-with>

or 

<dtml-with "REQUEST.environ">
    <dtml-var HTTP_REFERER missing>
</dtml-with>

if you want :-)

If you are experimenting with WIN 2000 try creating a NETWORK MAPPING
(WEBDAV) to a ZOPE FOLDER.

1. Click on Network
2. Click on Add a Network Place
3. Enter the url to a ZOPE Folder
4. Done

You now should have a folder view in Windows that Maps to a Zope Folder.
Enabling all sorts of great things:

1. Editing and Saving back to the folder with Security
2. Drag and Drop assets into the folder with Security

Great work on the Implementation of WEBDAV!!! Thanks DC!!!

That's very good news! Unfortunately I haven't been able to 
install win2K yet to see how it worked - I know about one 
further tweak that a little microsoft birdie told me I could
use to enable editing of "unprocessed" source (i.e. double 
click on a DTML method from a web folder and have it open 
unrendered in your chosen text editor or something). It 
shouldn't be hard to add, I just need to get the time and find
a box that I care little enough about to put w2K on it... :)

They do not offer "normal" PHP as an option -- you could ask them if they would
quote it as a "custom" add-on.  With enough work, it might be possible to call
PHP through a Zope product;  I don't know enough about what support PHP requires
from the OS and environment to know if this is feasible.

Of course, I also can't think of any reason to use PHP, but that is another
issue altogether. :)

The render-method collects items from a catalog and calls these objects'
"render" method.
Unfortunately this raises an Unauthorised Error, whenever I do not use the
super-user account.
(Zope has encountered an error while publishing this resource. 

Unauthorized

You are not authorized to access render.

Ok, so I gave the calling Method the proxy-role of the Manager. No change.
The strange thing about it is, and that is what puzzles me, that it works
for another class (which does only slightly different things).

So, what now, hu?

Regards, Ingo.

Do you mean site usage statistics (page views, etc.)?

If so, how do you measure Zope's stats if it is running as a separate
server and logging separately?

ZServer runs at Port 80 and logs all of its activity to Z2.log. I have
Apache running on port 8080 and it is logging to its own access log. I run
Analog (and Webalizer) on the Z2.log (cron) and write it to the Apache HTML
directory. That way I can browse all the Zope stats I want while not having
to import the static HTML into Zope. This also works great for documentation
and other things that come as static HTML.

The site, though, is pure Zserver.

G'day,

    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the zope-announce mailing list and
    the Zope.org site.

    The ZWN is changing days!  The next ZWN will be published on
    Tuesday.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.


Announcements

  * ZEO will go Open Source

    ZEO, the commercial Zope scalability option from Digital
    Creations, will go Open Source. After a trial period in mid-April,
    it will be available to everyone by mid-May.

    ZEO (Zope Enterprise Option) turns Zope into a distributed
    transactional object system, allowing people to add processors,
    machines, and networks to scale their web applications.

    More information can be found on the ZEO Product page.

    http://www.zope.org/Products/ZEO/

  * Oracle 8i Setup file, by Chris Petrilli

    Chris has released his Oracle setup file.  This file is used to
    create the Oracle library.  It has been tested internally for a
    couple of weeks.  See Chris's announcement for a caveat.

    http://www.zope.org/Members/petrilli/Oracle8i

  * Zope LATEX Math, by Bruno Vernier

    On his site, Bruno describes how to use LaTeX notation to render
    mathematical expressions directly from Zope.

    http://ess.vancouver.bc.ca/zope/math

  * Users Group - Ohio

    James Orbin <jorbin33@hotmail.com> would like to set up (or would
    like to participate in) a Zope users group for Ohio.  If you are
    interested, please write James, or see:

New Products

  * Software Product: L10NFolder, by "fog"

    The author writes, "This is a subclass of the standard folder with
    some added bonuses. The L10NFolder support localized properties
    and search paths."

    http://www.zope.org/Members/fog/l10nfolder


Updates

  * Software Product: XML Document, by Amos Latteier

    XML Document has been updated to work with Zope 2.1.6.  The latest
    release is 1.0a6.

    http://www.zope.org/Products/XMLDocument

  * Software Product: Zope MySQL Database Adapter, by "mordred"

    "mordred" has released an update to the MySQL Database Adapter, by
    Michel Pelletier (Portland). This release is 1.1.4, and fixes one
    bug:

      - Fixed a bug that caused Zope to fail on selecting aggregate
      functions such as 'select max(number) from table'

  * Software Product: ZWiki, by "simon"

    ZWiki is a Wiki web for Zope.  Zope and Wiki are a good
    combination.  Wiki assumes that, in general, users are
    trustworthy.  Zope, with it's security and transaction history,
    makes it easy to trust users.

    ZWiki is a sort of anarchic collaborative authoring system.  This
    version, 0.5, streamlines the default pages and UI, and disables
    the experimental catalog support. This release is intended to be
    immediately usable out of the box.

Zope.org items

  * How-To: Changing Base Classes for a ZClass, by "AlexR"

    When you create a ZClass, you are given an opportunity to chose
    which classes it will inherit from.  Since ZClasses are often used
    for rapid prototyping, you will not always select the correct
    classes the first time.  It is quite a lot of work to create a new
    set of classes with the correct bases and to move all the contents
    into them from the old classes.  Armed with this How-To, you will
    be able to change the base classes of a ZClass in-place!

    http://www.zope.org/Members/AlexR/ChangingBaseClasses

  * How-To: Serve PHP/Perl within Zope, by "Mamey"

    "As you migrate your site to Zope, you may want to embed a
    previously created PHP or Perl directory tree within Zope. Or
    perhaps you found a nifty web application that is coded in
    PHP/Perl and want to serve it within your Zope site."  This is a
    bit more advanced than simply rewriting certain URLs to be served
    by a different server.  This How-To will actually allow you to
    embed the external content in dynamic Zope pages.

Thanks so much everyone for all the help...actually, I ended up still
being able to use Zserver (without pcgi)...I left  the cgi programs on my
separate non-Zope site...and then for the image source, I just used a link
to the site, with all the corresponding parameters to generate the
picture...like so:

<img src="http://www.mynonzopesite.com/cgiprogram?parameters">

This worked! So, I was able to keep the regular Zserver, and still do
calls (at least for an image generation) to a cgi program residing on a
completely different site...looks like I will stick with Zope now, since I
am able to do this. :-)

> What have you run into that makes you think there is a conflict?

When I would do "rpm -Uvh Zope-pcgi-2.1.4-1.i386.rpm"

I would get the following message:

"error: failed dependencies:
        Zope-zserver conflicts with Zope-pcgi-2.1.4-1
        Zope-pcgi conflicts with Zope-zserver-2.1.2-3"   

But I no longer need pcgi, so I guess this isn't a problem for me anymore.

Thanks Again,
Jessica

Nope ...

I installed Zope-2.1.4-linux2-x86 and worldpilot-release-1.0.4.tar from
the zope-topdir. It installs correctly in ~/lib/python/Products/WorldPilot,
but when restarting the server, there is no "WorldPilot" or something
similar in "Available Objects" ...

I did:

umask 000
mkdir /var/spool/worldpilot
mkdir /var/spool/worldpilot/storage
mkdir /var/spool/worldpilot/storage/user
mkdir /var/spool/worldpilot/sessions
mkdir /var/spool/worldpilot/user
chmod -R 700 /var/spool/worldpilot

I set "DOMAIN.py" to domain="math.uni-bonn.de"

I converted those ^M (meaning

not show up in the available objects	;-(

Still, those DOS-format may be part of the problem?!?!

Confused ...

User-defined role authenticationAdam,

Something before I answer your question.

Please don't send HTML formatted mail to mailing lists.

Not all members use clients capable of reading it correctly, it makes it v
difficult to decipher when using elm for example.

OK that said onto the question.

You need to create users that have that role and then set permissions
appropriately for the location in question.

For example try turning view permissions off for the location. then try
browsing to it.

I have defined a role, editor, in my Zope system. It is not clear to me how
to prompt a user who is not a manager to authenticate so that Zope will
recognize the user as something other than anonymous. Any pointers?

Help very desperate....


We have a Zope site running: 
	Zope version: Zope 2.0.1 (source release, python 1.5.1, linux2)
		(also happens on a seperate box running Zope 2.1.6) 
     	Python version: 1.5.2 (#6, Sep 22 1999, 10:32:58) [GCC 2.8.1] 
     	System Platform: sunos5, Ultra-2  

It seems that if a user hits a page that either does an intense database
query or iterates over a large number of items, all other users are
prevented from accessing any page....! This problem may to be related to
the dtml-in but we are not sure.

For example suppose user A hits the following page (before user B hits
his page):
<!--#var standard_html_header-->
<dtml-in "_.range(999)">
	<dtml-var "_['sequence-item']">
	<dtml-in "_.range(999)">
		<dtml-var "_['sequence-item']">
	</dtml-in>
</dtml-in>
<!--#var standard_html_footer-->

And User B tries to access this page:
<html><head>
</head>
<body>
This is test
</body>
</html>

User B is prevented from accessing his page until User A's page returns.

Please help ASAP

I'm not sure I understand this. Perhaps you could rephrase the question.

We're phasing out hosting in favor of DASH (Dedicated Application Server
Hosting). This is not a price quote: For about $200/mo, you can get a
Cobalt RaQ3 that's all yours, hosted in our colo facility. Other
Linux/UNIX platforms supported are VA Research and Sun. If you want NT

The RaQ3 is a Intel-like setup (AMD K6-2, I think). Earlier models used an
embedded MIPS CPU. I have no personal experience with either, but we use a
fair number of them (and some older RaQ models). Zope ought to run just
fine on it, but I've never tried.

I'm doing some Zope development on a VA 500 (dual P-II-350), and we have
two of them for mailservers. No complaints. They come with Red Hat. Using
my own RPMs for now.

Of course, the *other* one needs to allow one to write to the own

Message-ID: <Pine.LNX.4.10.10003291624590.20418-100000@kenny.comstar.net>

Environment: Red Hat Linux/Intel, Zope 2.1.6, GenericUserFolder 1.1.0

Problem: I have a GenericUserFolder in a folder in the root folder. When I
log in to the initial Zope management screen, with a user with both
Manager and Owner roles (andy), I get this as debugging output:

2000-03-29T21:23:04 PROBLEM(100) GUF gudid is   

Even though I am not going into the folder with the GUF. Probably this is
due to just accessing contents information. Note that it says "gudid" and
not "gufid", which is what's in the code, which is a bit odd. It's also
printing some squirrely 8-bit character that doesn't paste in.

The folder with the GUF (XXX) has acquisition turned off for all
permissions, and all permissions enabled on Manager. The GUF itself has
normal security. In addtion to this, the user is assigned the local roles
of Manager and Owner in both XXX and XXX/acl_users. It doesn't seem to
matter whether these local roles are assigned or not.

If, as my user with Manager and Owner roles, I try to get into XXX, this
happens in the debug log:

------

The first three messages seem okay to me. The problem is that it is only
validating my user for the Anonymous role, and from then it seems to be
working as it should: It pops up a login document. The login stuff and
authentication seems to work properly. But it is not getting the correct
Roles from the top-level acl_users. The superuser works as you would
expect, until you look at the debugging info.

The difference here is on the first try (with andy), it crawls up twice
and fails each time, but with the superuser, it again crawls up twice
(gets just the Anonymous role at first), but on the second crawl,
validates the correct roles (note that manager appears twice).

Tracebacks dont look useful, just raising the LoginRequired exception, and
the only reason I have a traceback is because of debug mode.

Is this a bug (whose bug is it, anyway?) or a feature?

(BTW, that's a Python XXX, not a porno XXX. So don't flood the box looking
for pix of hot naked teen action. You won't even find any hot Python
action yet.)

Subject: [Zope] Zope in Jpython
Message-ID: <000501bf99d0$f37f0b60$770da8c0@bbs>

Zope is greate, all reviews say so. Most of the reviews complain the
documentation.

I believe all come to known zope have experience the same difficults and all
those remains can feel the power of zope.

Not only the documentation is matter. Under the greate architecture, zope is
inconsistance, non-intutive, and mistiness.

To be fast to market is not enough, it must also easy to maintain, endure
greate and fast change to make zope success.

To make good use of zope, one should paid more attentation on content
instead of control. Making separation of control and content as deep as
possible. Write re-usable, structural components.

I believe the following is very important :

1. re-introduce unified naming convention. encourage developers to change
over this
2. move un-necessary codes from the zope kernel to user space: <base> <lang>
...
3. support of unicode
4. make zope content easy to co-operative with current technonlgy especially
search engines. zope oodb is greate, but it prevent other apps to access the
data, so it is difficult to contruct a local search facility.
5. support cvs style versioning
6. multiple output format
7. new scripting language, encourage separation of content and control, may
be more xsl and xpointer style.

Converting zope to Jpython have the following benefits:

1. Unicode support
2. draw other java components : for example, several  xml tools being
develop in Apache.org is very useful.

If a complete re-write is not economic, at least DC should consider how to
separate the content and control in zope, make the syntax easy to learn and
use.

Ok, I've got the z sql method & odbc working correctly, and from a screen i
can input a date ( as text string) and product which then returns a nice
 and fast! ) graph of dates on the x axis versus avg values on the y. Now
from the documentation you can only get back 2 variables to use in the graph
but i need to plot about 5 Y values. So i thought about multiple graphs but
can't get that to work either.
    My solution was to create 5 radio buttons asking for what type of plot
they want, then based on the button selected fire off the appropriate
<action>. I'm new to Zope so i can't seem to get the Conditional statement
to work right on the <submit>. Anyone with any experience in any of this
please send suggestions. Thanks.

I have a sprinkling of Pystones for everything from the original Qube to a
P3-700:
http://weblogs.userland.com/qube/stories/storyReader$289

If you're doing any Zope work, you might consider as a minimum a RaQ3. Even
then I would think twice. There's a massive performance boost with the
P3-600 and P3-700.

I don't have any results for a RaQ3, but based on the CPU, it's not at all
an ideal Zope environment.

If you want a fast, cheap, Zope box look at the G3-450s. Even an iMac. Or a
Celeron. But not the Cobalt lineup.

Hi All,

Ive created a Product on my site that clones a file, then changes its
properties and
places the new file into whatever folder Im accessing that Product from.
It was working fine until I moved a bunch of folders. Basically, In the root
folder I
had a folder called website, then within that, folders called topstories,
sports,
weather etc. I copied the topstories, sports, weather folders to the root
directory and
then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to
access
manage_changeProperties". I am listed as a Manager of the site though, and
seem to have
full permission to do anything. I have discussed this with the superuser and
we can't figure
out why this happening.

Hello:

I'm not getting dtml-let. I use it to create a variable that I can access, correct?

Say I want to initialize a counter, and change it from 0 1 each iteration of a loop.

This will print out rows of a table with alternating background colors:


<dtml-let x=0>
</dtml-let>

<dtml-in "getElementsByTagName('book')" >

<dtml-if x==0>
	<tr bgcolor="DDEEAC">
<dtml-else>
	<tr>
</dtml-if>


write out some html

</tr>

<dtml-if x==0>
	<dtml-let x=1>
	</dtml-let>
<dtml-else>
	<dtml-let x=0>
	</dtml-let>
</dtml-if>

</dtml-in>
</table>
</dtml-with>



The let and if syntax is not good, and I can't read anywhere on how you would accomplish this type of
construct.

Few.

> Bad idea? 

Many.

Java is not an open platform.  Zope depends very much on the current
CPython implementation. Java has 'stability' issues, depending on what
vendor/platform/day of the week it is.  No in-house Java expertise.  Add
to this the list of debatable reasons why doing anything at all in Java
is a bad idea.  The bottom line is probably that we don't trust Java
like we trust C and Python.  If Java sticks around for as long as either
C or Python, then maybe I'll trust it a little, but never more than that
as long as it is a closed platform.

>It seems like a natural way to increase the performance of Zope while

Increase?  I think that's highly debatable.  We could put just as much
effort into increasing the performance of the CPython JVM or rewriting
components of Zope in C and probably get a much higher performance
return than depending on any one of a number of wildly different Java
implementations to give us that.

Consistent, everywhere?  This would require incredible re-writing and
probably break alot.  We'd rather come up with some newer, cleaner
interfaces and deprecate the old ones.  You're in luck, because now you
can propose new interfaces and corrections for existing ones, complete
with your prefered unified naming convention at the Interfaces Wiki:

I'm not sure what you mean by user space.  Zope is pretty well
segmented, we do need to clean up the application itself a bit.

> 3. support of unicode

Ah, as soon as python does, we do.  Also, soon there will be a Japanese
Vocabulary to support Japanese searching of text, and after that we are
going to try Chinese.  In Zope 2.2, using these examples, you can create
a Vocabulary object for the language of your preference.

This is kind of vague, nothing in ZODB is specific to the way Zope
stores its objects, currently Zope uses a FileStorage but there is
nothing preventing you from creating an XMLStorage or a
FileSystemStorage or a ReiserFSStorage or what have you.  Doing what you
want here can be done right now, it just has do _be_ done.

> 5. support cvs style versioning

Same as 4, all of the hooks and technology is there to support this, it
just needs to be done.

Can you define this better?

Well, there is some experimental stuff going on, but probably not
anything like xsl or xpointer, more like dealing with templates applied
to textual content that has structure.  Also some people are working on
introducing some more xml based tools in Zope.  Keep in mind also that
all the hooks are there, you just have to come up with an
implementation.  There is nothing in Zope that says you can't look at
the entire thing as XML or whatever, in fact, this can all hapen right
now.

This is one of the few genuine benefits, and soon it will be supported
in CPython so it's not a very pressing issue.

You can still use those components with Zope; why would you want them
all to be in the same language?  If those components have well defined
interfaces that Zope can work with why does it matter what language they
are written in?  I don't see this as a benefit.

Yes, we are working on these issues right now.

<dtml-let> tags only set that variable within the <dtml-let>context</dtml-let>
tags. 

The task you wish to do would much easily done using the variables set by
dtml-in. Eg <dtml-var sequence-index> will print out the 'count' if you like
for the list.

<dtml-if sequence-start> </dtml-if> (from memory?) will evaluate if it is
the first iteration of the loop.

<dtml-if sequence-even> and <dtml-if sequence-odd> will evaluate odd and
even iterations of the loop, which is what it apears you want todo.

Check out the zope quick reference document for documentation on
this

To concur with Michel --  JPython is a wonderful java prototyping
environment.  I know that people use it to do real work, as well...

But, I'm really not sure that it gains you much, given Java's high
footprint on anything that is non-Windows/non-Solaris.  

Also, JPython loses some of the nicer features of python (such as
multiple inheritance; at least the more recent functional versions
did, last I looked, 6 months ago).  This might be problematic,
depending on the guts of Zope.

If you really want Java, I suggest sticking with Servlets.  Or fork
the source code... 

But Digital Creations, please don't reimplement Zope in JPython...

best,

Let me warn you, you are allready thinking too procedurally.  Remeber
DTML is a _template_ language.

Let defines a new scope for variables, the scope being defined by the
let block.  Each time you use the let tag, you are creating and then
immediatly destroying the scope of your variable.  If you want to use
'x' in your DTML code, that code must be contained in the let block that
defines x.

What you are doing is easily done using the 'sequence-even' attribute.

<dtml-in "getElementsByTagName('book')" >
  <dtml-if sequence-even>
    Print stuff for even rows
  <dtml-else>
    Print stuff for odd rows.
  </dtml-if>
</dtml-in>

Message-ID: <38E2BA94.FF282F9B@suprize.com>

Hi,

    Since zope was introduced, I've created a handful of objects in
the nice application server and make great progress on several projects.
Thanks to DC and supports from people in this forum.

    Lately, these handful of objects keep growing and, from time to
time, I need to use find an object ID based on my vague memory. The
"find" tab in the zope interface grabbed my attention. But it seems
only accept full ID name to be put in the search field. Is there a way
to let "find" search by pattern or wild card characters? I've tried
*<pattern>%, %<pattern>%, or just <pattern> but with no luck. Please
advise and sorry for my bad memory for which only part of the names 
can be kept for a short while.

However neither of the above works, the latter gives a traceback error,

The above is used inside a DTML Method which is called by passing parameters
to it from a DTML Document. qry_name is one of the parameters being passed.

Any help appreciated.

etcUserFolder is an older piece of unsupported software that may have
compatability problems with newer versions of Zope.  I don't know if
anyone out there maintains it actively.  Without similar reports I would
tend to believe that this is because etcUserFolder has not be changed to
reflect recent changes in the API.

You can do some string matching with the 'expr' field, this lets you
type in a python expression that is evaluated against each object, for
example "id[3:] == 'bob'" would match all objects beginning with 'bob'. 
There is no regular expression facility.

This probably won't be expanded on because to a point the find tool just
doesn't scale.  If you want advanced wildcard searching of textual
content, use a Catalog.

I think it's a thread problem but not anything linux related, or at
least I'd need to see proof of that.

Wait another day, and try -t 2.  See what happens.

I wonder if the fact that manage_changeProperties was a latecomer to
security makes it different in other ways.

Subject: [Zope] Problems using DateTime in dtml and python. Help...
Message-ID: <38E2F888.51937800@ne.mediaone.net>

I have been building an interface for call reports from a MySQL database
on linux slackware 7 using
recent source distributions of Zope ,MySql and python. Besides a messy
bout with the ZMySQLDA
source, which is now not an issue,  I've  done OK. The problems:

1:

  I can call the DateTime() function from dtml like this-
    <dtml-var "_.DateTime(a_later_time) - _.DateTime(an_earlier_time)">
and I get what I need - a duration of time- but in days.  Is there a
method to change this to
minutes and seconds or do I just do my own math ... result * 24 * 60
etc... Whenever I try to
use the  DateTime  objects, eg fmt=DayOfWeek etc, I get invalid
attribute errors.

2:

I would rather do this work in an External Method, but when I try to use
DateTime() in a method
I get a Name Error when I try to update the Eternal Method in Zope.

So I went  to the python command line.
>>> from DateTime import *
Traceback (innermost last):
 File "<stdin>", line 1, in ?
ImportError:No module named DateTime

Obviously, I have some work to do, but what ? Recompile Python or Zope ?

How do I get DateTime to be recognized as a module?
I noted that the contents of  the Setup file in
/Zope/lib/python/DateTime are commented out-
 # install DateTime.py
 # install DateTimeZone.py
I uncommented them for kicks and reinstalled Zope with the same results.

It seems to me I'm missing something OBVIOUS.
And help greatly appreciated...

A GUF object has just been instantiated. The squirrely character needs

Its a bug. I'm putting together a patch release as we speak, and I hope
to have this fixed (next on my list). I was hoping that the 2.1.6 release 
would make all this crawling-up-the-tree business unnecessary but the 
change proposed doesn't seem to have been implemented.
(see http://lists.zope.org/pipermail/zope-dev/2000-January/002940.html )
I vaguely remember that the LoginManager for the PTK was going to make
use of this, but I havn't had time to pay attention for the last month or
so :-(

The Anonymous role being returned the first time is a recursion check
kicking in - during the authentication stage, we need to access your
methods in the GUF, which kicks in the authentication system again...

My bug.

I need to get the ZCatalog to update it self when I do new postings.
I have tried this

<dtml-call "Catalog.manage_catalogFoundItems(REQUEST, RESPONSE, _, _,
obj_metatypes="MyClass")">

But I'm not sure about the REQUEST and RESPONSE...

Subject: [Zope] problem with dtml-if
Message-ID: <v04205500b508b9940b8b@[130.227.115.56]>

hi,

I have this code in a dtml method called "test":

<HTML><body bgcolor=#ffffff>

<form action="test" method="get">

<SELECT NAME="day">
	<dtml-in 
"(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26 
,27,28,29,30,31)">
		<OPTION VALUE="<dtml-var sequence-item>"<dtml-if 
"_['sequence-item'] == day"> SELECTED</dtml-if>>
			<dtml-var sequence-item>
		</OPTION>
	</dtml-in>
</SELECT>

<input type="SUBMIT" name="SUBMIT" value="go">
</FORM>
</BODY></HTML>

It should "remember" the day selected and choose that as the default 
when making the select box. But for some reason the sentence:
<dtml-if "_['sequence-item'] == day"> SELECTED</dtml-if>

Doesn't work. I have also tried ... == _[day] ... == 'day'
...and a lot of other stuff but with no positive result.

I start the page with zope:8080/test?day=1

Regards

What can I do to logout with standard basic authentification?

[exec. summary -- concurrent requests becoming serialised; suggestions]

Hi,

I ran your test script on our zope server, and managed to view many other
pages while zope was parsing the page...

It looks like you might not have enough available threads (or maybe database
connections?). 

It's strange that only one request at a time is processed -- are you perhaps
using Zope in single-threaded mode (using pcgi_publisher; see
doc/WEBSERVER.txt for details)? You can set the number of threads Zope uses
by changing NUMBER_OF_THREADS in Zope.cgi; the default is 4. Note that
increasing this number will also increase Zope's memory footprint, as each
thread gets its own copy of the persistent object space.

It may also be that your machine is simply choking on that test script -- it
takes a while for zope to parse and render it. Despite python switching
between threads every n bytecodes, such a script (rendering one million
items) is going to put quite a load on the machine!

On your database queries you may be using a database adaptor that doesn't
give up the global python interpreter lock during transactions. This
prevents other threads from executing. What database and database adaptor
version are you using? See http://www.zope.org/Members/petrilli/DARoadmap
for details. There is a brief description of why the interpreter lock exists
in the python FAQ, section 4.88 (http://www.python.org/doc/FAQ.html#4.88).

Although unlikely with only one user, it's also possible that you could be
running out of database connections. By default, a maximum of seven
connections can be opened to any database you add. This limit can be set by
adjusting pool_size in zope_dir/lib/pyhthon/ZODB/DB.py (later versions of
Zope allow you to tweak these things in a custom_zodb.py file; try searching
the mailing list for details). Note that increasing pool_size will again
increase Zope's memory footprint, as query results are cached on a
per-connection basis.

hth,

Hope this is not too stupid a question:

How do I test a version without saving changes?

When I use the view option from within the management interface I only get
to see the 'live' (ie public) version and not the version that I'm working

Hi,

With basic authentication, the user's browser caches the username and
password, and sends them along with each request. All you can do to
invalidate the cached values is raise an "Unauthorized" exception.

<dtml-raise type="Unauthorized">
 You have been logged out. Please log in again.
</dtml-raise>

This sends an HTTP 500 Unauthorized back to your browser, which should
display the basic auth. login box again.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.12.html for
details.

Try:

_['something'] means I want the value with the literal key of 
something.

_[reftosomething] means I want the value with the key which is the 
value of reftosomething, if that makes sense.

The problem with this is that the browser will not clear its cache of this
valid username/password unless the user clicks 'OK' on the login dialog box
that pops up.  If the user clicks 'Cancel' then the browser assumes that
the user doesn't want to change the username/password, and keeps the
existing one in cache, hence, a reload of the page will be successfull.

Does anyone know of any tricks to get around this?

Hi Jonathan,

You might want to check with the ZIP - Zope Internationalisation
Project. There was some talk about a word by word translation service
lately. You might find interested partners there! You can find the
ZIP-Maillist home at <http://www.eevolute.com/mailman/listinfo/zip>

Really? What would you put on the Macs? Linux, OS X or MacOS?

What makes the Celeron superior to the Cobalt-setup in your opinion?
I thought the Cobalts where rahter high-speed (full) pentiums and
that the Celeron is not well suited for server use??

In my browser (Netscape) this works if you're following a link after
aborting this process.
Another (not very nice) method is using java-script closing the windows.
Recently found no better hints.

Thanks for pointing that out. 

As I understand it, this is a limitation of the HTTP Basic Auth. spec. RFC
2617 deals with this, and says that a client may preemptively send the Auth.
header with requests without receipt of another challenge (section 2). The
browser sends this information for every request in the zope realm (if it
didn't, you'd get the login box on every page). The server also sends an
authentication required header for every page that is protected, so this
behaviour in fact is quite logical.

The only way around it is to use a different authentication mechanism, like
Generic User Folder, et al.

Oh, yeah, and I meant 401 Unauthorised... what a week...

So, ZTables is going to die silently? I don't know much about it, but
considering the number of times I use TinyTable I would say that
ZTables is a needed datastucture for handling larger amounts of data.

Of course I understand and encourageDC to sell it as a commercial
extension, but I have problems understanding why they don't release it
to
the public if they lost interest. Anyone from DC?

Hello!

My current ISP has no interest in supporting Zope and will not install some
kind of 'Long Running Process', so I can't install it myself...

Can someone recommend an ISP that supports Zope?

I found Armored Internet, but it seems like they only support Zope for
Business Services (and they also charge $37.50/month for it). So if someone
knows an another ISP, preferable cheaper, PLEASE let me know!

Hi,

I have learning Zope for 6 months and have been
following the mailling list. I come across the
following news :  

Python 3000 will not be backwards compatible. 

Question :
How will it affects Zope ?

Sorry to be picky here but, quoting from Table 15 on page 21 of the DTML Guide:
missing - Provide a value to be used if the ariable(sic) is missing, rather than raising a KeyError.

This is what I ended up doing :-)

Is it just me or does it seem silly that:
<dtml-var HTTP_REFERER missing='/'>
works as expected but
<dtml-var "REQUEST.environ['HTTP_REFERER']" missing='/'>
doesn't, even though they're logically the same thing?

The KeyError should be caught when evaluating the expression as well as the name in dtml-var :(

I might chuck this in the collector at some stage...

That's because 'day' in the request is a string which you compare to an
integer.
Try:

<dtml-if "_['sequence-item'] == _.int(day)"> and your code should work
fine.

BTW you can shorten you <dtml-in> statement with the range tag:

<dtml-in "_.range(31)"> will give you the same output.

Zope won't run on MacOS. It would have to be either Linux or OSX or BSD.

It runs Python faster than a PIII of the same speed. I'm assuming that's
because the cache, while half the size of a standard PIII, runs at full CPU
speed. That it supports only a 66MHz bus and memory may cause it to not
perform as well under load. I don't know. I  don't have the resources to
test that sort of thing properly.

There's more to a building a server than its Pystone rating, but it's a
start when you start looking at putting together a box.

Subject: [Zope] variable SQL insert method
Message-ID: <38E3368A.98950BF0@rrsg.ee.uct.ac.za>

Hi,
I have a database with 3 tables. I would like to create a ZSQL method
for inserting data into the tables. I started by creating a separate
method for each table, but that seems a bit of a waste. Ideally I would
like to have one method, "addEntry". The template would look something
like:

<dtml-if "tname=='supplier'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar sup_name
type=string>  etc...);
<dtml-elif "tname='manufacturer'">
INSERT INTO <dtml-var tname> VALUES (NULL, <dtml-sqlvar man_name
type=string> etc...);

</dtml-if>

The problem is that I have to specify the arguments in the argument
list, and the arguments are different for each if clause in the above
code. Is there a way around this?

thanks
Allen

if get_returner_id(xxx) returns an empty list, then it _should_ return
nothing.

as the <dtml-in will be executed 0 times.

(untested, and will need finishing off)

Put ALL the arguments in the ZQSL method's arguments section, but give them all defaults (eg put
myvar_name='' in the arguments section)

Now, to make sure the right ones have been supplied, you need to put in an extra level of dtml-if in
each branch of your current dtml-if, something like:
<dtml-if "tname=='supplier'">
 <dtml-if "_.has_key('var1') and _.has_key('var2')">
  ... your insert here...
 <else>
  ... do something to warn of the error, such as a dtml-raise
 </dtml-if>
<dtml-elif ...>
...

Hi,
I just ./stop and ./start'ed two Zope servers that were taking up 
rather a lot of memory;

   PID USERNAME THR PRI NICE  SIZE   RES STATE   TIME    CPU COMMAND
   841 nnle      12  33    0  395M  318M sleep 177:24  0.00% python
   834 nnle       9  23    0  531M   14M sleep 101:20  0.00% python

Is there any way of telling what objects are taking up this memory - 
could it be a memory leak in Zope at all? I'm using src-2.1.3 on 
Solaris because I still use the /REQUEST hint to see what my 
variables are.

cheers,

Now - LinuxPPC (my Mac at home that gets 900 pystones is usable for 
me to do dev work on).
Later - choose from OS-X or LinuxPPC
You can't (easily) use MacOS because Zope has some unix-centric parts 
that don't translate well to the Mac.

>What makes the Celeron superior to the Cobalt-setup in your opinion?

The Pystone scores are higher
Celeron-400a
Pystone(1.1) time for 10000 passes = 1.78
This machine benchmarks at 5588.87 pystones/second
vs
Qube2
Pystone(1.1) time for 10000 passes = 8.81
This machine benchmarks at 1135.07 pystones/second

Sorry, not qualified to answer that bit. All I do know is that we 
have a 700MHz PIII here that gets 10,500 Pystones against our 
Enterprise 450 with ... 2700. As the maintenance on the Sun kit is 
roughly the same price as the PIII, you could say I'm not overly 
impressed with the Sun...

Hello,

I've just discovered Zope, and would like to get more information about it
as it
seems quite interesting . But I'm not sure I could use it for the web
project I'm
working on.

First, I'd need to stock XML files in an object database like the one
provided with
Zope. What kind of requesting language may I use ?
XQL ? Xpath ? XML-QC ? OQL ? XOQL ?

Second question, is there a java API integrated in Zope ? If not, is it
possible to
interface Zope with others java products as Resine, servlet engines, EJB
server...?

Thanks in advance

Bruno Faure

Subject: [Zope] dtml-return'ing the result of a SQL select (does not work)
Message-ID: <38E35092.A8838265@knoll-is.de>

Hi,

I just tried to implement something as described in the How-To
	How To: Use GenericUserFolder with an SQL database
It does not work. The problem boils down to the fact that I can't
dtml-return the result of a SQL query.

I wrote the Z SQL Method 'qryTest':
	select * from mytable

This method can be executed without problems. It displays all rows in
the table.

And I wrote a DTML Method 'returnData':
	<dtml-return qryTest>

When calling the method I get
	Resource not found

Traceback (innermost last):
  File D:\Programme\uZope\lib\python\ZPublisher\Publish.py, line 214, in

Watch out, this might be confusing, since Subscribe is a permission
referencing in the other direction (eventually actually needs to be
placed somewhere seperately). You have to set that checkbox in the 
account, that is supposed to access that data in it's default view,
or in that account session you must use the "Go-control" to switch to
the shared account.

Does the method return the full text if you call it
directly?

like:

http://your.zopeserver.dk/yourZclass_instance/PrincipiaSearchSource

you should get the raw contents of the instance..

If you don't , somethings wrong with the method or its
placement..
i think product/product_entry/methods is the right place..

If you get the raw text returned, the fault is with your
Zcatalog.. Have you updated it after adding the pythonmethod
??
- Checking the status-view of your zcatalog can often help to see
if it has updated correctly..

Subject: [Zope] ZSQL arguments
Message-ID: <E12afEQ-0004UC-00@marvin.nipltd.com>

Hi,

ZSQL methods can have two types of string argument, string and 
required, where required is a non-empty string and a string is (one 
assumes) a potentially empty string.

Although does not say in the ZSQL users guide, it would be nice if 
strings were also not required to exist as arguments, which to my 
mind is the logical progression of allowing an empty string.

The reason I want to do this is that I am writing sql methods which 
build queries based on the existence of certain arguments.  
Obviously I can code the logic to test for empty strings, but it 
would be neater and simpler to be able to simply have

<dtml-if myarg>
...

The other reason this would be a neater solution is that it would 
avoid the need to set up lots of empty arguments in the dtml which 
calls the sql method.

Comments?

Cheers,
Stephen

Sorry, Tom,

I was blabbering last time about hasattr. The right solution is of course:

def recursiveMethod(self, obj, result):
     if hasattr(obj, aq_parent):
            result.append(obj.title)
            recursiveMethod(self, obj.aq_parent, result)
     return result


which you will have to call like this (assuming you external method in Zope
is called recursiveMethod):

<dtml-var "recursiveMethod(<obj>, [])">

Working with a keyword argument didn't work for me. I'm sure someone can
explain you why (but I don't have time for sorting that out right now)

Zope returns a key error on "set". The same appends for 'append' method, as if,

I eventually found the answer by creating an external method :

def SetValue (self, dictionnary, key, value):
    """Ajoute une valeur ŕ un dictionnaire"""
    dictionnary[key] = value


Which you can call with <dtml-call SetValue (REQUEST.form, 'tata', 'titi')>. It
works !...

*Increase* performance by rewriting in Java?  You've been reading
Sun's press releases again and, worse still, actually believing them;
don't make that mistake! :) 

I can think of any number of improvements that could be made to Zope,
but a translation into another language, with no clear idea of what
actual problem would be solved by the translation, isn't one of them.

	Also, take a look at: www.step-thermodynamics.com

	Their primary business is selling specialized cooling systems
	for processors, which they bond to the processor.  As a result
	they only sell their cooling system with a processor.

	They provide a lifetime guarantee on what they sell, and they
	also guarantee that a processor will run at a specific MHz
	(which in the case of a Celeron 333a processor is 500 MHz if
	I remember correctly).  That particular configuration uses a
	100 MHz front side bus speed.

	A friend of mine has got a couple of dual processor boxes with
	Abit BP6 motherboards (socket Celeron motherboards) with two
	Celerons each running at 500 MHz.

	For any task that requires fast cache, but not a lot it, they
	are great systems.

Ok.. so I opened up a can of worms.

Thanks to everyone for setting me straight. I do think, though, that
performance and benchmarking should be an issues on the tips of DC tongues.
I have been doing a lot of benchmarking (and will publish results soon)
trying to figure just where the bottlenecks are (DTML, references, SQL,
size, caching). The good and bad news is that there seems to be no
difference in many of the different tests. I can get a MAX of 40 requests
per second, and that, is that.

The reason I asked about JPython and performance was because I get a lot of
developers telling me that Servlets are much faster. Now, that being said I
am about to set up a website with servlets and pound on it till it bleeds to
see if it is true.

One of the comparisons that would be nice on Zope.org would be the servlets
vrs Zope. (JServ, Enhydra, etc).

Thanks,
J

Hi,

I ran into trouble when trying use PIL (python imaging lib) in zope
product. 
The problem is that zope's App.ImageFile is used by PIL's internals
instead of PILs ImageFile and of course this doesn't work.

Any ideas how to fix this problem?

Sure. You just need to 'packagize' PIL. 

Place the PIL directory somewhere in your
Zope's python's path. Add an __init__.py
to the PIL directory.

Inside the __init__.py place the following:
# Add any additional PIL modules that you want imported.
# This is one, long import statement that my email clien will
# wrap.
import Image, ImageFile, ImageEnhance, ImageDraw,  _imaging, GifImagePlugin, 
JpegImagePlugin, PngImagePlugin, BmpImagePlugin

Message-ID: <38E37C81.365E6845@knoll-is.de>

Hi,

I just found something in DT_Var.py which I mean is a bug.
The function thousands_commas uses a hard coded ',' to as thousands
delimiter. I think it would be best to use locale.format instead for
this purpose.

Is there anybody how can incorporate this change into Zope?!

One more related question: How can I print the current currency symbol
in Zope? I could not access the locale namespace in a dtml method.

Thank you.

I can think of one: I wrote my first program in php in some minutes, while
my first zope silliness took me days.

 - BUT -

now I'm in this mailing list so I can flood you with questions.


Please keep in mind that I'm a total newbie, at the moment I know
little more than Nicholas Petreley about Zope. I'm fluent with python
and slow but steady with html.

My first site is for an antique trader (my father): four languages,
lots of photos with descriptions, some search methods, some registered
users, a private addressbook.

There will be an "uploader" interface for my brother, a public and
a "frequent customers" interface. I don't think the Photo product
is stable enough for use, so I'll try and write something by myself.

If I use a "pure" zope provider, do I need to keep the photos on
the ZODB?

Is it possible to write to the file system via an external python
method, so that I can:

 * receive a photo with netscape
 * give it an unique filename
 * write it to the file
 * update the info (filename, descriptions) on a SQL table

 and then

 * reference (from DTML) or delete (from python) the photo by the
   filename stored on the SQL table

 ?



The trouble with Zope is not that it isn't documented, but the
documentation at first makes me fell stupid. I don't know why.

It is like loving a girl you didn't have the chance to talk to.
It makes me feel stupid.

Maybe the fact that I need a 21" to look at my source, and I have to
look at the source of the page returned by the browser to see the
stack trace with my error (when there is a stack trace), has something
to do with the stress I am having during my learning sessions.

Will zopezilla (or mozzope)? enhance my Zope Experience?



Thank you for reading this far.

Subject: [Zope] namespaces and uploading files etc
Message-ID: <38E37FB9.25E18857@rrsg.ee.uct.ac.za>

Hi,
I've written an external method that will write some data to a specified
location in the server's file system. I would like a user to be able to
upload a binary file, and for the external method to then write that
file to the local file system. I understand that when a user uploads
something using an <INPUT TYPE="file" NAME="uFile"> that the file is
encapsulated in a FileUpload object. That data would be accessible in my
external method using REQUEST.uFile.read().
However, suppose my external method is defined as :
def writeFile(self, file, rootdir, filename):
    ...write data using f.write(file.read())
    return filename

I would like the argument "file" above to be a reference to
REQUEST.uFile. Also, the "filename" that is returned would be the actual
filename used (it may have been altered due to filename clashes or
whatever).
I tried using the following dtml to call this method:
<dtml-let filename="writeFileLocally(_.None, _, _.uFile,
  '/usr/local/ZopeExternalFiles/Components', _.uFile.filename)">
<dtml-var filename>
</dtml-let>
However zope complains...
I'm obviously still fumbling with zope's namespaces.

Thanks
Allen

Comparisons of this type are always quite difficult to pull off. I know that
the applications I've created are rather Zope-specific. I designed them for
Zope and they take advantage of Zope's features. It would be really
difficult to try to do a reasonable comparison, because Zope has features
the other systems don't. Sure, I could make a servlet that acts kind of like
an app of mine, but how would I simulate retrieval of data from the ZODB and
acquisition and the like?

I'm sure that I'm paying a performance price for things like the ZODB and
acquisition... but I think that price is offset by the productivity
improvements that I get as a result.

Convert the DateTime objects to seconds before subtracting::

  <dtml-let early="_.DateTime(an_earlier_time)"
            late="_.DateTime(a_later_time)"
    <dtml-var "_.float( late ) - _.float( early )">
  </dtml-let>

You can use '_.int(..)' or '_.long(..)', to, truncating to whole seconds.

Put an __init__.py in the PIL file that says:

import Image, ImageDraw 

and have it import whatever you need from pIL.

Then you can just do 
	import PIL
in Zope.


The Poll Product has some instructions on this.

I have a zope ISP (hurrah.com) and am trying to determine how fast/reliable
they are.  Is there a way to compare Zope ISPs for speed and reliability.  I
would imagine speed is the easiest to test and reliability is subjective and
based on historical knowledge.  I am just having trouble telling if my test
version of Squishdot (and my test site in general) is really supposed to be
as slow as it is.  I am used to working with a large ISP (Verio) with no
Zope.

Any ideas on how to compare or test would be greatly appreciated.

Isn't it 32kb for Postgres?

Unfortunately, the photos are up to 350kb.

Ok, ten smaller objects could do :-)))

Subject: [Zope] Date Zone Problem
Message-ID: <20000330165619.76957.qmail@hotmail.com>

Hello,

Last March 26th Portugal changed to GMT+1.

ZopeTime() returns, for instance, "2000/03/30 16:00:00.000 GMT+0".

16 hours is correct but I think it should give a GMT+1 at the end of
the date?

I found this because I'm having this problem:

I have a object with a property date that when created first time
with the factory add method uses the manage_changeProperties with
the date value added to request with,
<dtml-var "REQUEST('date',ZopeTime())">.

The object is cataloged. Then I make a search to get the objects and
sort them by date. When I render this objects dates If I format the output 
using fmt="%C %Style" the date presented is "2000/03/30 15:00:00.000 GMT+0", 
one hour less!!

Since this is not right cause the real hour is 16 I work around the
problem and discovered that the TimeHours() function returns the correct 16 
hours. That resolved my output problem.

But then again a problem emerge. I have a form to update my objects 
properties, in this case, the date property. This form when rendered
writes a <input type=text:date name=mydate>. When submited a strange
thing happen. If I output the date of this updated object with the
fmt="%C %Style" format the hour will now be correct, i.e, 16.

I though then that the "text:date" type in the html was important for this 
happening.

But the problem now is that when sorting my objects this one will be sorted 
using 16 as the hour but other objects that I did not updated, i.e, dont 
passing them trough the "text:date" form, will be giving 15
for the sort.

Questions:

Is this a internationalization of zope related problem?
Does the GMT+0 instead of GMT+1 is a zope/python bug?
Am I missing something about the international date zone system?

Best Regards,
Julio

I did a private extension to DT_Var.py which incorporates 
the modifier "german-money", which returns 
1&nbsp;234,5 for 1234.5 
Just because I needed it.

I did not mention it to the group since I want a much cleaner and more
general approach for supporting multiple languages.
I dont think we could handle this with locale, since the actual page
could be in a different language.

I've since moved back to 2.1.4 and it works fine there. Will be setting

Can you tell me what products? I know that if you are using

then deleted the website folder. Now when I go into the sports folder, for
instance and try to
use the Product I made, I get a message saying "you are not authorized to

No, Zope can't, especially Python can't, because it trys to evaluate
something like sequence - item.foo.

So try

<dtml-with sequence-item>
 <dtml-call "foo">
</dtml-with

or:

<dtml-call "_.['sequence-item'].foo">

I've had exactly the same problem. I put 2.1.6 and it breaks (user
authenication), I put back in 2.1.4 and it works fine. I'm also just
using straigt Zope. Just so you know it's not isolated.

Too much effort to fix it.  We don't have the time, we are working on
too many projects as it is, even discussing ZTables takes more time than
we have.

Releasing it to the public would still take time, someone would need to
maintain it, but to maintain it they'd first have to understand it, it's
complex; as complex as the catalog.  If we threw it out to the community
I suspect it would die there also.

Besides, TinyTables could be updated to support more efficient data
structures like the BTrees that ZTables and ZCatalog use.  ZCatalog + a
more efficient TinyTables is probably 99% of ZTables.

If one makes heavy use of TinyTables but needs more functionality (but no
RDBMS) I suggest he/she takes a look at Metakit. (www.equi4.com). This
amazing software deserves more attention than it gets and has already a
very nice interface to python. Returned rows behave more or less like
Zope Record objects. You can do sophisticated stuff like joins
selects etc but it can also be used in a manner similar to TinyTable. It
is transactional and *very* fast/efficient. Currently in not multithreaded
so one needs to serialize requests. I think the author, Jean-Claude
Wippler mentioned that he is working in a thread safe python version (the
TCL one is out).

A Zope interface would have beed nice ...

yes, only in pythonish these are called attributes.

Hm, I tested it. It works for me. Can you tell me where it doesn't work and
in what way? Does it fail. Is there a traceback? Remember it will still bail
out (with an AttributeError) if the object has no attribute title!

That is because there is no high level framework with servlets.  There
is no standard authentication framework, acquisition framework, standard
object/relational model, template language, through the web managment
system, object publishing over multiple protocols... servlets don't come
with an HTTP, FTP, PCGI and a FastCGI server.  All of this you get with
Zope out of the box.

It may very well be.  With the subsequent open sourcing of ZEO however,
you could scale your Zope application invisibly to a hundred machines,
how far can  you scale that Servlet without making any changes to it at
all (or not paying money)?  Requests per second is only one tiny factor
of scale, and when you scale beyond a handful of machines it becomes
less and less important.

That's because Zope can't write it (that's what the 'w' means).  The
user you are running Zope as (if you are root, Zope turns itself into
nobody) does not have permission to write to your var/ directory.
 
> Q1.  Why is Zope looking for Z2.pid if I installed it WITH PCGI?

The Z2.pid file contains the process id of Zope, it allways writes it
and has nothing to do with PCGI.

> Q2.  If Zope still needs Z2.pid with PCGI, how do I get the file there?

Zope will put it there if it can write to the var/ directory.

Though I haven't seen any clear statement to confirm this, I believe this
is a very large part of DC's decision to release ZEO. By enabling Zope
clusters ZEO addresses pragmatically several limitations inherent in the
curent state of Zope / Python. As a side effect, redundancy brings with it
answers to concerns regarding reliablility, of hardware, if not Zope
itself, in a mission critical setting.

While some may see throwing hardware at performance / reliability needs, as
inelegant at best, to others with hopes of rolling Zope out for the long
term, this seems like a perfectly reasonable solution. Python and Zope will
continue to improve, and all Zope users will benefit. For now, leveraging
commodity priced hardware is actually about as elegant as it gets.

So, DC has heard and answered, and Zope is the better for it!

The FileStorage format is portable across platforms.  The objects in
that filestorage are portable across Zope, _as long as_ your target Zope
has the same products installed as your source Zope.

Hm. In the example

<dtml-in list>
  <dtml-var foo>
</dtml-in>

the iteration will change the namespace to that of each sequence-item
automatically. So the foo asked for will always be the foo of the current
sequence-item. Things like
<with sequence-item> or "_['sequence-item']..." are not necessary.

If you iteration is by a number of IDs, as your question suggests, though,
the example is not enough. When you iterate over a list of IDs, the
sequence-item will be an ID (that is a string) and foo will have no meaning
(it will throw an AttributeError).
There are two way of remediating this:

preferrably use objectValues(), like so

<dtml-in objectValues>
   <dtml-var foo>
</dtml-in>

If you _have_ to use a list of ids, things get more complicated

<dtml-in Ids>
  <dtml-var "_.getitem(_['sequence-item'].foo)">
</dtml-in>

(sorry about that)

All code is untested, but it should work.

OK, this is probably a stupid question, but how do I fix it?  I tried:
changing the /Zopedir/var/ folder and file settings to user=ewalstad,
group=users and had no luck running ./start.  I also tried copying one of
the other .pid files and renaming it z2.pid; that didn't work, either.

Any advice is appreciated.

Replying only to the last sentence:  Add a DTMLMethod in the root of your Zope
(call it maybe "debug_request"), with the following body:

  <dtml-var standard_html_header>
  <dtml-var REQUEST>
  <dtml-var standard_html_footer>

This works fine on 2.1.4+ -- they only suppress the "direct traversal" of
REQUEST.

Hello all. I'm just starting my first Zope site, and I'd like to create
a feedback form for the site. I have very little "useful" experience
with DTML, especially for logic. Once I create the form, how do I write
a DTML script to process the input (like linking entries to variables,
testing valid answers, raising errors, etc.) ANY help whatsoever would
be greatly appreciated, and all the useful stuff I learn I'd like to
make a how-to from. Real world solutions like this in Zope are few as
far as documentation go....

thanks in advance,

Eron

Access to a version is based on a cookie set in your browser.  So
when you go into the version object and click on work in version,
the cookie gets set.  If you then access your site from that same
browser session, you *should* see the version.  This, at least, is
how it works for me <grin>.  You should see the version on the view
tab, too, though, so I think you must have some problem with your
browser sending the cookie.

Hello everybody!

Please join me in welcoming Shane Hathaway to the Digital Creations
team!!

From Shane's man page:
"""
I come from a small but growing town called Magna, Utah. I
always considered it an underrated city in the Salt Lake
Valley.  I enjoyed my friends and neighbors there and some
of them keep in touch even now.

I have been programming since I was eight years old.  I
enjoyed the Commodore 64 so much that television I still use
is actually a Commodore monitor.  I had to learn to program
early because my parents refused to buy any software--if I
wanted software, they said, I'd have to write it myself. So
I did!

I enjoy singing.  I have sung in many choirs over the years
including the Cyprus High madrigals.  I have sung enough
solos for various functions that it's now easier for me to
sing a solo than to give a speech in public.

If you ever want to butter me up for something, give me a
genuine Brazilian feijoada.  Include every part of the pig
but avoid the hairy stuff.  Having spent two years there, I
hold Brazil close to my heart.

Not long ago I wrote Web Academics
(http://www.webacademics.com), software for delivering
courses over the web.  It was designed to handle specific
needs requested by educators as well as the needs I was
aware of as a student.  I am working on porting the
education-related components of Web Academics to Zope.

Zope and Digital Creations are very interesting to me
because the product is built on solid foundations and the
company is built on a solid philosophy.  I am excited to
begin working with the team.

Subject: [Zope] Mysterious Netscape Upload failure
Message-ID: <38E3CED8.E4A2561D@palladion.com>

After banging my head on it for a couple of days, I just resolved a really ugly
problem for any Zopista who uses Netscape:  any form which contains a file
upload button was timing out, failing to send data to Zope (e.g., I couldn't
create DTMLMethods!).

The underlying cause of this was Netscape's poor tempfile hygeine:  their file
upload control handler was creating tempfiles, which it then never bothered to
clean up.  Eventually, it exhausted the tempfile namespace, at which point it
looped pointlessly trying to create a tempfile with an unused name.

I tried several reinstalls, tweaked preferences, all to no avail.  The solution
was to scrub the temp dir of all the ns*.tmp files -- everything is hunky-dory,
now.

Looking-for-the-voodoo-doll'ly,

Tres.

Additionally, I would suggest removing the "Acquire Permissions Settings" from the 
"View" permission, and making the "View" permission only available to managers.

This is easy to do, assuming you called the DTMLMethod above "debug_request" and
created it in your Zope Site Root, then you could:

1. Navigate to http://mysite.com:8080/debug_request/manage_access
2. Scroll to the bottom of that long page.
3. Uncheck "Acquire Permissions Settings" next to the "View" Permission/
4. The "Manager" box should already be check, verify this.
5. Click the "Change" button near the bottom of the permission list.

Forgive me if I over-explain.

Message-ID: <200003302208.PAA10382@ifopen.com>

I've got a simple python class that has a data member that holds a list of 
strings (among other things).  I can laod values into this list fine.  
And can query the object and the list is populated.  However, after  I 
restart Zope,  the list for the class instance is empty.  The other data 
values in my class retain their values just fine.

I've got other classes that hold similar lists for which this doesn't occur.

I'm banging my head against a wall - any ideas?

Lets see here ...

KnowledgeKit
LocalFS (installed, not currently in use)
SybaseDAv2
PSQLInput
Cookie Cutter (likewise not in use)
TinyTable (see above)
A small,simple 'nes article' product
Calendar
Standard Zope stuff

That's it.

It is it's own server, so no need for SiteAccess.

In a word, yes. :-)

Here's how I do it on my site. This line tells me when a particular object
(a file object as it turns out) was last updated:

<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=Day>,
<dtml-var "_['Bookmark.htm'].bobobase_modification_time()" fmt=pCommon>

The output looks like (for example):
Tuesday, Mar. 7, 2000 11:35am

The extra '_' business in my dtml-var tag is necessary because my file
object has a '.' in its name. I believe that

<dtml-var "spamobject.bobobase_modification_time()" fmt=Day>

should do it if you don't have a '.'

HTH,
Tim

I think you'll find the How-To on creating a mail form very helpful. You'll
find it at http://www.zope.org/Documentation/How-To/Mailform

Good luck.

Thanks, this is what I was looking for. I was adding object names on the the end of it, rather than

I followed the instructions in PIL.  I created a directory called =

I removed the zope/bin/python file, and changed the start file to use =

You're probably mutating the list without informing the instance that you've
changed it.  If you do:

thing.stufflist[4] = 'newstring'

or

thing.stufflist.append('newstring')

...then 'thing' has no way of knowing that 'stufflist' has changed, unless
you replace 'stufflist':

# This can be confusing, since it doesn't look like it does anything
thing.stufflist = thing.stufflist

... or tell 'thing' explicitly:

# This is the official interface to mark an object changed
thing._p_changed = 1

Your changes will also get saved if you happened to change any other
attributes of 'thing' in the same transaction, but as you've discovered this
is unreliable at best.  Explicit is better.

Cheers,

After a minute or two, the directory listing shows up.  Clicking to edit a file

Just on this subject :

a) You may find the Perl mandarin text-splitter at www.mandarintools.com
   very useful. I rewrote it in Python once but my Perl sucks so you may 
   wish to do this yourself. Otherwise, e-mail me for copy ... it's so 
   short I'm sure you'd rather not trust mine though.

b) What algorithm do you use in your searching of text ? Is it just a
   simple frequency tally ?

You will need to use an external python method.

I am currently writing one that will take any sql query and a file name as its parameters and put the results of the query into the
file as  comma or tab delimited records with or without the the field names in the first record.

Will post info here when I have it completed

Subject: [Zope] How do I download the results of a large Query


I would like to set up a link to some SQL query results in comma delimited
ascii that will download the data rather than display it.  I am having two
problems.  First the data is coming up in the browser and I want them to
download it without having to right click and select download.  Second,
before the SQL is completed the browser times out.

I think if I solve the first problem,  the second will be Ok,  Any ideas?

Subject: [Zope] ODBC and MS SQLServer Problems
Message-ID: <20000330163600.A3429@24.64.237.96.ab.wave.home.com>

I am trying to get Zope to play nice with MS SQL Server.  They are both installed on the same Compaq Proliant server.  I can create my database, make it accessible through ODBC and then add a ODBC Connection in Zope by picking my ODBC connection from the list.  I can then use the connection just fine for SELECTs and UPDATEs for a little while (30 mins to an hour). However, eventually I get the following error:

Error Type: sql.error
Error Value: ('S0002', 208, "[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'users'.")

where 'users' is a table name.  Up until this point, it was accessing 'users' just fine, and I can still run queries on it from the SQL Query Analyzer app so I know the table is there.  My only option at this time seems to be to delete the whole database and create it again and recreate the tables.  This isn't acceptable if this system is to actually be used.

Can anyone who has gotten SQL Server and Zope working post explicit instructions.  Or better yet, let me know what is causing the above error.

Thanks.

Not a lot if Zope continues to use Python 1.[5, 6, 7].

<opinion type="personal">

People are making a bigger deal out of this than it needs to be.
I admire Guido for taking a stance and fixing the problems he
perceives in his language;  I've had to support "backwards
compatability" issues in a commercial interpretive language
before, and "It Sucks(TM)".

Here he is being honest, stating that there will be change, but
not knowing the extent, and people are carrying on like it will
be the end of Python as we know it (or to use an Australian term,
"carrying on like pork chops").  When Python 3000 comes out, it
will not render all the Python versions before it automagically
obsolete; people will still be free to use whatever version they
most feel comfortable with (heck, I came across a site the other
day still running 1.3, and quite happy with it - it runs their
_current_ applications fine).  If there is a large enough groundswell,
there is nothing stopping other people from maintaining the "1.7"
version, but I personally can't see that happening (unless Guido
goes mad and puts braces in to denote blocks :-).

It's an Open Source language - you actually have options.

One thing that is kinda amusing (to me, at least) - the fuss I'm seeing
about this is, in a way, a testament to just _how_ _good_ a job Guido's
done as Benevolent Dictator. I've been using python since v 0.9.mumble,
and there's been _very_ _very_ few times where I've had to go back and
change working code because of a python upgrade.

And that's not just the python scripts, I'm also talking about C
extensions. 

Thinking back to a previous place of work where we had perl software of
around 10-12K lines of code, it seemed like every bloody minor rev of
perl5 would break something in it.

P3K has been talked about for a long long time as the "chance to fix
stuff" (ok, it used to be known as Python 2.0, but...).  I, for one, 
am looking forward to it. (particularly if the types/classes split 
goes away).

Here's a silly thing that's always niggled me : 

How do you get Zope to render the DTML that is 
stored in properties of a ZClass ? 

eg. Consider you have a ZClass with a string 
    property called 'my_property'

    In an instance of this ZClass, you set the 
    value of 'my_property' to "Hello <dtml-var x>"
    where x might be a string, integer, image etc

    Now, if a DTML method were to call <dtml-var my_property>,
    it would display "Hello <dtml-var x>"
    How can we get the DTML to be executed too, so that it
    displays "Hello [value of x]". Is there any easy method
    other than splitting this up into different fields ? 

Apologies if this is such a trivial thing. It's
escaped me for ages.

Heh, I just ran into this same problem a few days ago.  For some reason
PIL doesn't install a __init__.py (or at least the RPM of it didn't). 
Check /usr/lib/python1.5/site-packages/PIL for a __init__.py.  If it
isn't there, then make one with this content:

import Image, ImageFile, ImageEnhance, ImageDraw, _imaging,
GifImagePlugin, JpegImagePlugin, PngImagePlugin, BmpImagePlugin

if you are starting zope as root, the following (from the Zope root
folder) should work:

chown nobody access
chown -R nobody var

then you can start.  If you're starting zope as some other user, then
replace "nobody" with other user.  All the files in var need to be owned
by nobody or the starting user.  Copying Z2.pid won't work, because zope
sets it afresh each time it runs.

No, unfortunately, it's not possible.  You can use the Sybase database
adapter to talk to SQL Server 6.5 from Linux.  SQL Server 7 evidently
has a different wire protocol which prevents it from working against the
Sybase DA.  There is no ODBC support for Linux in Zope, and though there
have been rumblings about getting such a thing going one way or another,
nothing concrete has happened.

Not entirely true. You won't be able to use some SQL Server 7 features if
you use the Sybase adaptor, but the standard stuff should work fine.

Once freetds is thread safe, it should also be useful.

It is very possible to get ODBC connectivity using the OpenLink UDBC Multi-Tier
drivers and ZODBCDA. You will have to do some minor hacking, and if you want 
access to any fields longer than 128 bytes, some larger hacking :-)
(There is I think a major bug in SQLGetString in sql.c too that causes
Zope to crash -- I think I have fixed it... at least w.r.t. the UDBC drivers,
sz should be SDWORD [for OpenLink drivers anyway]).

The UDBC drivers are thread-safe (so they say).

I have a FreeBSD box quite happily talking to MS-SQL-7, I implemented this
for a client, so I can tell you how to do it, but, not what I did to get it to
work.The joys of contract programming.

I seem get restarts often when going into the management screen on one
of my servers.
All is dandy until I go to the management screen, then I wait a couple
seconds while it restarts.

Sounds like you are really after the LoginManager, which according to
reports is usable for non-PTK, but not for PTK.

It comes with the PTK, but is a seperate product in development.

Thanks for the answer, I'll have a look. But I would like the basic
structures to be compatible with the PTK, as I might want to employ that
later on. Any comments?

where qry_name is the *name* of the ZSQL-Method that I want to use. Thus if

Message-ID: <00033114332105.02681@tokey.kedai.com.my>

hi all,
i'm thinking of hacking zdiscussion to use rdb as the backend instead of zodb. 
but before i start anything, i'd like input from you learned zopistas.

me:- i'm not a REAL programmer.  just a hobbyist.  some of my concerns
-will a level  2 da be sufficient for high write site?  i'm thinking of using
postgres
-if i were to retain  what zdiscssion has, willl it suffice to have just one
table?  i would like to tie this to AUTHENTICATED_USER.  so i want to use user
db as the authenticating agent.  is it advisable to just put the forum table in
the user db database?  
-how would you guys do the tree from sql?
-what other improvement can be included?  what pitfalls to avoid?
-anybody done this(zdiscussion/confera with sql backend) yet?

this is just a start.  i'm not sure whether i'll succeed.  but i'll die trying
:)

thanks.

Yes, that's because the split does something else. 
Don't know if you want to pursue this further, but if so, let's try and
track it down

How do you call it from dtml?
Have you tried it from outside the ZClass (in a test situation)?

If there is a traceback, it will show in the same way as normally, I
believe.

Hi,
OK, part of my zope pages are inserted from another site (like frames,

What must make my product is taking these external pages, treating the
HTML code and print it with some new features.
When the user clicks a link of this inserted page, I want to intercept
the request, treat the URL to go and searsh the HTML code to insert it
in my page.
Is it possible to do it???
How???

Thank you for your attention.

Is there any possibility to get some debbugging information to know

Is there any possibility to see from within python if the smbvalid

Is there any way to calculate a roles effective rights on a object in Zope?
I currently have the situation that I can access two DTML documents

Trying to track the problem down, but I dont get it right.

What about this acquire permission settings checkbox?
Is there any special behavior when I added a local role in a

Can this affect acquisition of permissions of e.g. the anonymous role?

Ah, so I understand that it's not called with arguments. So you need
another external method.
Change you external method to look like this

def recursiveMethod(obj, result):
     if hasattr(obj, 'aq_parent'):
          result.append(obj.title)
          recursiveMethod(obj.aq_parent, result)
     return result


def ParentList(self):
    obj=self
    return recursiveMethod(obj, [])

Then make you external method refer to ParentList
This works without arguments from a testfolder. It should work from a
ZClass as well, but I did not test that.

Facile !... (façon de parler...) Deux solutions ŕ deux problčmes différents :

1- Pour rediriger une page vers une autre, utiliser la syntaxe suivante :
<dtml-call "REQUEST.redirect (<url>)">
Dans ce cas, on n'a pas accčs au contenu html de la page.

2 - Pour avoir accčs au contenu HTML d'une page extérieure au site, il faut
utiliser la méthode externe suivante (trouvée dans un HowTo du site Zope, que
je sois pardonné pour l'emprunt sans mention de l'auteur....) :
import httplib

def GetURL(site, filename):
 from httplib import HTTP
 http = HTTP(site)
 http.putrequest('GET', filename)
 http.putheader('Accept', 'text/html')  # we can handle text/html
 http.putheader('Accept', 'text/plain')  # we can handle text/plain
 http.endheaders()
 httpcode, httpmsg, headers = http.getreply()  # get response headers
 if httpcode != 200:
  raise "Could not get document"  # HTTP error
 doc = http.getfile()
 data = doc.read()  # read file
 doc.close()
 return data

Ensuite, aprčs avoir inséré l'External Method dans la hierarchie de Zope, pour
récupérer le texte html d'une URL distante, utiliser la syntaxe suivante :
<dtml-let mapage="GetURL ('www.toto.com', '/index.html')">

    //    Traitements...

</dtml-let>


3- Pour accéder au contenu d'une page interne au site, utiliser une référence
du style :
<dtml-let mapage="_['page_a_traiter']">

</dtml-let>


Et voilŕ !...

This becomes very funny, it doesn't work. It still returns nothing.
Although I found a way to get this working, I would really like to know the
cause why it doesn't work. I'll try something different right away.

Hi Rik,

Forget my previous message, I got it working now with hasattr. I made a

Message-ID: <000901bf9afc$bc8da9e0$0200a8c0@digitalview.com.hk>

I'm trying to assign the string:

1=1

to the variable criteria using this construct:

<dtml-let criteria='1=1'>

but I can't because Zope complains:

invalid parameter: "=1'", for tag <dtml-let criteria='1=1'>, on line 5 of
Create_List

Some playing around reveals that it doesn't like spaces and the equals sign
(=) in the string.

Am I correct in thinking that something delimited by single quotes (eg.
'this is a string') is a string? If so why can't I (or how can I) include
spaces and the equal sign inside the string.


thanks

Hi

Try <dtml-let criteria="'1=1'">

The bit inside the double quotes is evaluated as a python expression, and
thus returns the string you want.

See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.10.html

Unlike other tags, the dtml-let tag is quote-sensitive, requiring that
attribute values are quoted. So in the above code, you're trying to
evaluate the expression "1=1", which isn't valid Python code (you're
trying to assign a value to a value). What you want is:

	<dtml-let criteria="'1=1'">

the roles given to the user in the sub-folder *replace* the roles
defined in higher folders, due to the way user folders work. the user in
the subfolder must have the same role as in higher folders (so he can
traverse the higher folders), plus any new roles in the subfolder.

jcNTUserFolder was developped because htrd's NT User Folder has not this
functionality, which I needed also.

Thanks.

After scouring through all the docs that I can lay my hands on I finally
found an implicit reference to the above usage of dtml-let in "HowTo:
Advanced DTML techniques".

<dtml-gripe>
One of the main stumbling blocks in getting to grips
with Zope is the incoherent documentation. The information
one needs is scattered about in countless docs so a lot of
the time will be spent searching those docs. This isn't helped
by the fact that the guides and how-to's themselves contain many
errors in the examples.
</dtml-gripe>

But many thanks to the kind people on this list who have responded swiftly
to my questions.

<dtml-let criteria=="'1=1'"> should work.

In dtml-let, you write one pair of quotes to specify that your're writing a
python expression. Inside quotes you're writing python.

Examples of valid python expressions:
   'this is a string'
   23
   methodname

You can wrap up any of the above inside a pair of double quotes and then use it
in <dtml-let>

DTML-LET sintax:<dtml-let variable="exp"> </dtml-let>

So use:
<dtml-let criteria="'1=1'">
not
<dtml-let criteria='1=1'>

Or te best way ( I've  found it yesterday) :

<dtml-let valueVar="'var has value: %s'  % (var)">


All the best!

Thanks for the tip with the Zope Quick Reference! It helps a lot.
In my specific case however, I still have a problem. It may be caused by
permission settings, but I don' really think so.

I have a folder "sample_images" in the ZClass "foo".

I in the "foo_add" method I try:

<dtml-call "manage_clone(sample_images,'my_images')">

in the "with"-section. Things like "manage_addFolder" work there.

The result is:
"The object sample_images does not support this operation. "

Suggestions?

Thanks! Joachim.

Take a look and let me know if this is what you were looking to build.

I will add that I too am not a "real" programmer and while I have 
been using Zope for months I am still just ramping up.

Windows 2000 professional is the equivalent of NT Workstation.
on Windows 2000 server, there is two way of managing the domain: the old
way (with pdc/bdc,etc.), and the new way, with active directory. in
native mode, pdc/bdc support is disabled and my code rely on it. you may
not be concerned by this 'problem' because nt 2000 pro (aka workstation)
can't manage a domain.

bizarre, it should work. are you sure that Benutzers can *view* sub
folders? where did you create the administrator role? in the top level
folder or in the sub folders?
by the way, where do your users authenticate from? from the nt 2k pro
box (that is, the users are created *on* this box)? from a different
domain (and the domain controller is another machine)? until I can write
a better doc, also read in the zope archives the messages from 'Ava' and
'minf7'

I'm not at the office right now, so I can't do further tests. but I
should be able to reply on monday, at least.

by the way, if you want to force all users to log in, you may consider
using zope with iis, and let iis do the authentication. this may not be
possible with nt 2k *pro* (it doesn't work with nt workstation because
IIS requires nt server).

You should try, instead :
<dtml-let criteria="'1=1'">

A string is an expression, and expressions must be enclosed in double-quotes...

If you really want all content served out of mysite, you might want to
look into the SiteAccess product.

If you want just http://localhost:8080/mysite, try BASE1.

BASEn starts from the root and adds an object (from the current
aquisition path) according to n- BASE0 = root, BASE5 = root + 5 objects. 
BASE == BASE0

URLn counts the other way, starting with the current aquisition path and
removing an object according to n- URL0 = current path, URL1 current
path - 1 object. 
URL == URL0

The Zope Quick Reference has this information.

Message-ID: <38E4A089.9533A493@rrsg.ee.uct.ac.za>

Hi,
Say I want to call a dtml method that requires some extra variable, one
way is to set that variable in the REQUEST using REQUEST.set('name',
'value'), and one is able to call the dtml method.
Somebody suggested using the DTML-let tag to do the same thing, but I
haven't been able to get it to work:

<dtml-let variable="some expresion">
 <dtml-var dtmlmethodname>
</dtml-let>

when dtmlmethodname tries to access "variable" with <dtml-var variable>,
zope complains that variable does not exist. Is there a way of using the
let tag to accomplish this, or is there a different way?
Is using the REQUEST object the normal way of "passing" variables to
other methods ?
thanks
Allen

Perhaps something very stupid I'm doing, but I've a strange result here.


I've a ZClass which has the properties 'Title', 'Issue', 'Comment'.
This ZClass automatically reindexes itself in catalog.

Now, when I change the contents of Issue, Comment and then search the
catalog for the specific ZClasses, I get all the created ZClass instances.

However, when I change the contents of the Title and I again search the
catalog for these ZClasses, I get all but the changed instance back!
However, looking inside the catalog, the ZClass is still there!

I forgot even to mention one thing!

Only when Title is empty it is returned by the catalog! Otherwise it's
excluded from the catalog result list.

Tom.

---

Perhaps something very stupid I'm doing, but I've a strange result here.


I've a ZClass which has the properties 'Title', 'Issue', 'Comment'.
This ZClass automatically reindexes itself in catalog.

Now, when I change the contents of Issue, Comment and then search the
catalog for the specific ZClasses, I get all the created ZClass instances.

However, when I change the contents of the Title and I again search the
catalog for these ZClasses, I get all but the changed instance back!
However, looking inside the catalog, the ZClass is still there!

Is this a naming conflict? Or is it something else?

The editonly properties howto involved some python code were too complex for

If I just use the manage method, it will re-direct me to the manage screen

Subject: [Zope] Variable as record type or dictionary
Message-ID: <NBBBINPMKCEPBDEGNIEOCEBIDBAA.jcoruna@umd.es>

Hi Zopists!

I need to copy a record from into a <dtml-in> tag to use it later.

Suppose:

"Client" is a select ZSQL method (select * from Client where <dtml-sqltest
client_num type=string>).
----
<dtml-in "Client(client_num='2345')">
  copy the retrieved record in a variable
</dtml-in>
----
"OrderLine" is a insert ZSQL method:

insert into OrderLine
  (order_num,client_num,client_name,client_address,...,product_num,...)
values
  (<dtml-sqlvar order_num type=string>,
   insert the column "client_num" from the previous retrieved Client record,
   insert the column "client_name" from the previous retrieved Client
record,
   insert the column "client_address" from the previous retrieved Client
record,
   ...,
   <dtml-sqlvar product_num type=string>,
   ...)
----
Registering the order lines...
<dtml-call "OrderLine(order_num='OR4567',product_num='PENCIL-0067')">
<dtml-call "OrderLine(order_num='OR4568',product_num='PEN-BLUE-8')">
<dtml-call "OrderLine(order_num='OR4569',product_num='PENCIL-0045')">
<dtml-call "OrderLine(order_num='OR4570',product_num='PENCIL-0023')">
<dtml-call "OrderLine(order_num='OR4571',product_num='PEN-BLCK-1')">
<dtml-call "OrderLine(order_num='OR4572',product_num='PEN-031')">

----

Take in mind that I can't put the ZSQL method "Client" inside the ZSQL
method "OrderLine" because the Client method needs about 10 seconds to
execute and if every "OrderLine" method needs his time plus 10 seconds (from
the "Client" method) this can take over one minute for the above example
order. This is not viable! Awaiting 15 seconds to place the order is
acceptable but over one minute isn't.

The solution is to execute the "Client" method only one time. Any ideas how
can I copy the Client record?

Subject: [Zope] DST Zone Date, help needed!
Message-ID: <20000331145302.10067.qmail@hotmail.com>

Hello all,

I'm having a hard time with dates since portugal entered DST last March 26.

If I use:

<dtml-var "REQUEST.set('mydate','2000/03/31 15:00:00.000 GMT')">
manage_changeProperties(REQUEST)

I can get from "mydate" the utc hour (14:00) with the
fmt="a-la-C %H:%M" and the current GMT DST of Portugal(15:00) with
Zope's TimeMinutes().

If I use:

<form action="manage_changeProperties">
<input type="text:date" value="2000/03/31 15:00:00.000 GMT" name=mydate>
<input type=submit>
</form>

the fmt format and zope's zopetime() give me the same hour that
is the GMT-DST (15:00), i.e, somehow the "text:date" conversion is
ignoring the Portuguese GMT-DST and assume, in this example, 15:00 as
the UTC.

Since nobody is answering I'm going into the source to find where is this 
conversion. I'll get back with a solution... I hope :-)

Thanx,
Julio

Hi All.

and I have set the permissions exactly alike. Rendering the one class is
ok for non-super-users, but rendering the other one gives this:

It worked fine and give no special problem.

I have tried to update to the version 2.1.2 (RPMs) using Apache + pcgi.
Every time I try to use the zsql methods, zoe dies.

I have tried the latest version 2.1.6 (tgz). In this case I receive

Any suggestion ?

Can you not achieve the same thing with a single user folder in the

That's how I use NTUserFolder.

If you are fiddling with the setup of your pages you should do this

I briefly looked at the list's archive but did not find the actual answer.

2- Is there a way to purge the ZODB object history (ie. not the cache but the

The short answer is yes.

But your performance varies depending on how deep you want
to get into the subject. The most simple way to run Perl
CGI is:

(1) Use a Python external method to handle all CGI request.
    Let's call it "cgi_bin".

(2) Your CGI URL requests would be something like:
    http://www.mysite.com/cgi_bin?cgi=mycgi.pl&arg1=var2&arg2=var2

(3) Inside your external method, you check the values of
    REQUEST.cgi, REQUEST.arg1, REQUEST.arg2 and use Python
    pipe commands to launch the Perl interpreters and capture
    the output. (On Windows, use functions from the win32pipe
    module in Python's Win32 extensions.)

There was some discussion on all this about a week ago. Please
read the thread "newbie CGI question":

http://www.egroups.com/group/zope/showthread.html?start=26666

If you don't like the look of the URL, you can still use
Zope's SiteAccess product to tweak and interprete a URL like
htpp://www.mysite.com/cgi-bin/mycgi.pl?arg1=var1&arg2=var2

But in order to achieve decent response time, you will have to use
Apache + mod_rewrite + mod_perl + Zope. Which is more involved.

Hi again,

after read the mail I thought it could be misunderstood.

What DateTime returns wrong is the "GMT" part of, for instance,
"2000/03/31 18:08:58.3851 GMT".

It should return, "2000/03/31 18:08:58.3851 GMT+1".

Note: the hour is correct, but the gmt part no, should be added "+1".

Onderwerp: [Zope] Only allowing authenticated users to view document


I have a dtml-document which I wish to be viewed only by (certain)
authenticated
users.  I tried un-checking all the security permissions and the acquire
permissions boxes, but I can still access the method.
[cb] I guess you have the permission to view the rendered document as
manager
 Putting a
<dtml-var AUTHENTICATED_USER> in the form shows nothing when I test it (and
not
anonymous as I thought it would).

AUTHENTICATED_USER is an object , the html source of  your rendered document
will show its id
try: "AUTHENTICATED_USER.getUserName()" (with quotes) in your dtml-var tag,
which is a string representing the name of the authenticated user (or
'anonymous').

cb

El castellano tambien funciona aqui. ;) Podrias dar mas
detalles del mensaje de error? Asegurate de que el
duenno de las carpetas sea "nobody", para que no haya
problemas durante el proceso de makefile.

Could you provide the error message itself? Make sure that
the owner of folders are "nobody". (Usually I am lazy
and change myself to superuser, and then change everything
recursively into nobody.nobody for owner.group)

The owner:group of all folders is nobody.

The system is: 

	RedHat 6.1
	ZOPE 2.1.6
	Python 1.5 

i don't know what more tell you about the error.

We too have seen more frequent restarts centered around /manage
activity.  I have one user that I can tell when he starts working in the
morning by the first Zope restart of the day.  We have not been able to
get a consistent repeat of the behavior though.

We have three servers running with one taking most /manage activity and
that machine is the one that restarts the most.

>i don't know what more tell you about the error.

In case you have not realized, what you have provided is NOT
an error message. I don't know why you call it an error message.
That is why I asked you to provide the error message. :)
If you have an error message, please provide it. If not,
please don't call something an error message when it is NOT.

Por Dios, si no hay error, para que me asustas? :)

Please read the README.txt file and follow the steps there.

(1) First check your environmental variable is properly
    pointed. Do

    echo $SYBASE

    if it does not show the directory of installation of your
    Sybase database, you are in bad shape. You need to set this
    environment variable, preferable from the moment you reboot
    the machine, but if not, from your Zope's "start" file.

          SYBASE=/mnt/sybase1192
          export SYBASE

(2) Follow the instructions in README.txt

    cp Setup.linux Setup
    make -f Makefile.pre.in boot
    make
    cp sy_occ.so ..

Then it'll work.

(Me parece que tu problema no es Sybase adapter, tu
problema puede ser Unix/Linux. Parece que no eres
familiar con Unix/Linux.)

All,

Has anyone used Andrew Kuchling's Oedipus package (parses and displays
ODP data from dmoz.org) with Zope ?
In the Oedipus 0.0.7 distribution there is a .gz file with what looks
like a Zope product distribution.
But unpacking it in the usual place for zope products doesn't make it
visible in my Zope Products folder.
I am using Linux RH 6.1, Zope v 2.1.6, Oedipus v 0.07.
Any known problems ?  Do I need to have XMLDocument imported before
Oedipus will import ?

Help !

Hi,

How do I store an object in RAM during Zope's up-time?

I don't want to store it as a persistent object.
And I don't want it to disappear after a http transaction
(so REQUEST variable is no good.)

I would like to be able to create this object given
a particular http transaction, and afterward I may
want to modify it. This is a bit like session management
data, but it's a piece of data that is shared by all
sessions...

regards,

Hung Jung

None other than to check the Zope-ptk archives for info, I haven't used
it yet myself.

As far as I know there is not currently any such mechanism.  I wonder
if the PTK people have thought about this?  I haven't gotten around
to signing on to the PTK list yet, but I really need to.

Go to database management on the control panel, and compress your
database.  This will delete old transactions up to whatever point
you tell it, thus shrinking the database.  It won't have any affect
on rendering speed, though; from what I understand ZODB is designed
to keep read performance high regardless of the number of transactions
recorded in the database.

I read you could define a ZClass instance's method as a field-index of a
ZCatalog; but it's not working for me.

The DTML method dept_code is simply:

  <dtml-return "_.string.split(jobcode,'-')[0]">

When I call the method directly it returns a single character, the first
character of the jobcode.

The method dept_code is defined as a field-index of the ZCatalog JobsCat.
But when I access JobsCat thus:

 <dtml-in "JobsCat(meta_type='Job Opening', sort_on='dept_code')">
   <li>
   <a href="<dtml-var "JobsCat.getpath(data_record_id_)">">
            (<dtml-var dept_code>) <dtml-var jobcode>: <dtml-var title></a>
 </dtml-in>

the items are not sorted, and dept_code is null.

Can anyone see what I'm doing wrong?

Hi Tino

A lot of my pages are served by sqlsession, and sometimes I have to do
maintenance on the sql tables, and take down the database server.

Hmm, here is what I have, in DTML Method aaabbbccc::

 <dtml-var standard_html_header>

 <p> Calling asdf with variable 'foo' = 'bar', using the let tag: </p>

 <dtml-let foo="'bar'">
   <dtml-var asdf>
 </dtml-let>

 <dtml-var standard_html_footer>

And in DTML Method asdf::

  <p> <dtml-var foo></p>

When I view aaabbbccc, I see::

 Calling asdf with variable 'foo' = 'bar', using the let tag: 

 bar

which is exactly what I expected.

Can you see any differences between your code and mine?

Subject: [Zope] REQUEST weirdness . . .
Message-ID: <38E534D6.133329E4@globalcrossing.com>

'ello.

Bear with me on this one; I'm having worlds of problems coming up
with any kind of coherent way of expressing the problem. :)

I have a form which contains the following:

<input type=text name="street.address1:record">
<input type=text name="street.address2:record">
<input type=text name="street.city:record">
<input type=text name="street.state:record">
<input type=text name="street.zip:record">

To parse this data, I would ordinarily just use a dtml-with:

<dtml-with street>
  <dtml-var address1>, etc, etc, etc
</dtml-with>

No problem.  This, however, is where things get interesting.
I'm passing the data from this form to a "confirmation"
page.  The data from the first form will be simply put into a bunch
of "hidden" fields, where the user will be prompted to REALLY do what
they were doing, or cancel back to the original form.

Now, I don't want to have to re-code the confirmation page every
time I add a new value to the main form, or remove an input for
whatever reason.  What I figured I would do is the following:

<dtml-in "REQUEST.form.keys()">
  <input type=hidden
         name="<dtml-var sequence-item>"
         value="<dtml-var "REQUEST.form[_['sequence-item']]">">
</dtml-in>

This works fine for all the values in the form which aren't using
the ":record" tag, but obviously for my address, I'll 
need to iterate through it.  ie:

<dtml-in "REQUEST.form['street'].keys()">
  <input type=hidden
         name="street.<dtml-var sequence-item>:record"
         value="<dtml-var "REQUEST.form['street'][_['sequence-item']]">">
</dtml-in>

( In the original code, "street" wasn't hardcoded, and I just wrapped
  that statement around a dtml-try, where the except clause was my
  original dtml-in. )

This code doesn't work.  Upon closer inspection, the following line
was the culprit:

  <dtml-in "REQUEST.form['street'].keys()">

Upon even closer inspection, *none* of the dictionary functions would
work.  Not even <dtml-var "REQUEST.form['street']['address1']">

Then I decided it was time to just see exactly what was in the object.
<dtml-var "REQUEST.form['street']"> yielded the following results
(I had just entered sequential numbers for all five inputs):

address1: 1, address2: 2, city: 3, state: 4, zip: 5

Here's the output of <dtml-var "REQUEST.form">:

{'street': address1: 1, address2: 2, city: 3, state: 4, zip: 5, 'submit':
'submit'}

The original <dtml-with> code still works, as does
<dtml-var "street.address1">.  I've also tried using getitem:

<dtml-var "_.getitem('street')['address1']">

I'm quite confused.  It would appear that "street" really *isn't*
a dictionary at all, yet somehow the <dtml-xxx> tags still work.  What's
going on here?  I'm quite befuddled.

Thanks a lot in advance for any help, and apologies again for the
convoluted message.

Message-ID: <Z4C$7kAIdS54EwQ+@compkarori.com>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Hi,

I previously posted that I was having problems with Zope and Interbase
losing the ODBC connection ( on Win32 ).  This would happen whenever I
entered the web management interface, and at other times when I could
not identify a cause.  I then had to shut Zope down and restart it.
Zope would not allow the ODBC connection to be made otherwise.

I was using the much older Visigenic driver because the Intersolv driver
truncated varchar fields (a known bug).

However, recently I joined the Interbase mailing list, and one of the
Interbase staffers suggested I retry the Intersolv driver and recast the
varchar field as char to work round the truncation

viz. select cast(myvarchar as char(n)) as myvarchar from foo;

I am pleased to report that this works well, and over the last few days
I have not observed a single disconnection.

Furthermore, I have noticed that the very first use of the OBDC
connection after Zope started always gave an error.  This problem has
also now disappeared.

For interest, my experimental server is using a PII 300 overclocked to
450, 128Mb ram, NT4 server, and an IDE hard drive served on an ADSL
connection.  There are about 20,000 items in the ecommerce database.  I
am also using Interbase to do Zope session management.

You can reach the server by using the url below ( a PHP script on my
static server redirects to the ADSL box).

I'll post an update if the situation changes.

In addition, Interbase Corp has expressed an interest in supporting Zope
by helping/writing native drivers for Linux and other platforms which
are supported by the new Open Source Interbase 6.0

I know that in the CVS now, record objects support the Python mapping
interface (which is what you're trying to do) but before that, and I
think this is the case for the 2.1.x branch, this wasn't supported, and
you needed to access the object by attribute only.  This makes what you
want to do in DTML pretty impossible (but not impossible from python).

I guess you can try waiting for the next main trunk release, or you can
modify your record objects to support a mapping interface just like the
CVS does.  It's a very simple class in the
lib/python/ZPublisher/HTTPRequest.py module.  This is probably the
simplest solution to your problem.

Nope.  In your case it's an object with _instance attributes_ that
contain your values.

Hi there,

For some reason Zope would suddenly hang and it's thread would consume 99.9% of CPU usage.  The first time this happened the problem magically disappeared after a complete reinstall. Here's what happened while casually throwing bannerexchange code into the default DTML document.

standard_html_footer
    </td>
   </tr>
  </table>
  <dtml-var bannerexchange>
  </body>
 </html>

bannerexchange
 <dtml-var standard_html_header>
 <h2><dtml-var title_or_id></h2>
 <p>
 <!-- bannerexchange code -->
 </p>
 <dtml-var standard_html_footer>    <---- Oops!


I'm on Zope 2.1.6, do future version prevent me from making accidental infinite loops like this?

BTW: I get exponentially more done with Zope every day.  Thanks for Zope.
